If you want to efficiently display big number of images I recommend using IPyPlot package

import ipyplot

ipyplot.plot_images(images_array, max_images=20, img_width=150)

There are some other useful functions in that package where you can display images in interactive tabs (separate tab for each label/class) which is very helpful for all the ML classification tasks.

Leveraging David Dehghan's answer above, the following works in Python 2.7.13:

from PyPDF2 import PdfFileWriter, PdfFileReader, PdfFileMerger

import StringIO

from reportlab.pdfgen import canvas
from reportlab.lib.pagesizes import letter

packet = StringIO.StringIO()
# create a new PDF with Reportlab
can = canvas.Canvas(packet, pagesize=letter)
can.drawString(290, 720, "Hello world")
can.save()

#move to the beginning of the StringIO buffer
packet.seek(0)
new_pdf = PdfFileReader(packet)
# read your existing PDF
existing_pdf = PdfFileReader("original.pdf")
output = PdfFileWriter()
# add the "watermark" (which is the new pdf) on the existing page
page = existing_pdf.getPage(0)
page.mergePage(new_pdf.getPage(0))
output.addPage(page)
# finally, write "output" to a real file
outputStream = open("destination.pdf", "wb")
output.write(outputStream)
outputStream.close()

I agree with most people that using ordinal is probably a bad idea. I usually solve this problem by giving the enum a private constructor that can take for example a DB value then create a static fromDbValue function similar to the one in Jan's answer.

public enum ReportTypeEnum {
    R1(1),
    R2(2),
    R3(3),
    R4(4),
    R5(5),
    R6(6),
    R7(7),
    R8(8);

    private static Logger log = LoggerFactory.getLogger(ReportEnumType.class);  
    private static Map<Integer, ReportTypeEnum> lookup;
    private Integer dbValue;

    private ReportTypeEnum(Integer dbValue) {
        this.dbValue = dbValue;
    }


    static {
        try {
            ReportTypeEnum[] vals = ReportTypeEnum.values();
            lookup = new HashMap<Integer, ReportTypeEnum>(vals.length);

            for (ReportTypeEnum  rpt: vals)
                lookup.put(rpt.getDbValue(), rpt);
         }
         catch (Exception e) {
             // Careful, if any exception is thrown out of a static block, the class
             // won't be initialized
             log.error("Unexpected exception initializing " + ReportTypeEnum.class, e);
         }
    }

    public static ReportTypeEnum fromDbValue(Integer dbValue) {
        return lookup.get(dbValue);
    }

    public Integer getDbValue() {
        return this.dbValue;
    }

}

Now you can change the order without changing the lookup and vice versa.

When TypeScript thinks that property "x" does not exist on "y", then you can always cast "y" into "any", which will allow you to call anything (like "x") on "y".

Theory

(<any>y).x;

Real World Example

I was getting the error "TS2339: Property 'name' does not exist on type 'Function'" for this code:

let name: string = this.constructor.name;

So I fixed it with:

let name: string = (<any>this).constructor.name;

Simply add the disabled class to the button instead of the disabled attribute to make it visibly disabled instead.

<button class="btn disabled" rel="tooltip" data-title="Dieser Link führt zu Google">button disabled</button>

Note: this button only appears to be disabled, but it still triggers events, and you just have to be mindful of that.

I recommend using python-dateutil. Its parser has been able to parse every date format I've thrown at it so far.

>>> from dateutil import parser
>>> parser.parse("Tue Jun 22 07:46:22 EST 2010")
datetime.datetime(2010, 6, 22, 7, 46, 22, tzinfo=tzlocal())
>>> parser.parse("Fri, 11 Nov 2011 03:18:09 -0400")
datetime.datetime(2011, 11, 11, 3, 18, 9, tzinfo=tzoffset(None, -14400))
>>> parser.parse("Sun")
datetime.datetime(2011, 12, 18, 0, 0)
>>> parser.parse("10-11-08")
datetime.datetime(2008, 10, 11, 0, 0)

and so on. No dealing with strptime() format nonsense... just throw a date at it and it Does The Right Thing.

Update: Oops. I missed in your original question that you mentioned that you used dateutil, sorry about that. But I hope this answer is still useful to other people who stumble across this question when they have date parsing questions and see the utility of that module.

Is this the expected behavior?

the json_encode() only works with UTF-8 encoded data.

maybe you can get an answer to convert it here: cyrillic-characters-in-phps-json-encode

Tested code, initially creates a single archive file, then splits it:

 gzip -c file.orig > file.gz
 CHUNKSIZE=1073741824
 PARTCNT=$[$(stat -c%s file.gz) / $CHUNKSIZE]

 # the remainder is taken care of, for example for
 # 1 GiB + 1 bytes PARTCNT is 1 and seq 0 $PARTCNT covers
 # all of file
 for n in `seq 0 $PARTCNT`
 do
       dd if=file.gz of=part.$n bs=$CHUNKSIZE skip=$n count=1
 done

This variant omits creating a single archive file and goes straight to creating parts:

gzip -c file.orig |
    ( CHUNKSIZE=1073741824;
        i=0;
        while true; do
            i=$[i+1];
            head -c "$CHUNKSIZE" > "part.$i";
            [ "$CHUNKSIZE" -eq $(stat -c%s "part.$i") ] || break;
        done; )

In this variant, if the archive's file size is divisible by $CHUNKSIZE, then the last partial file will have file size 0 bytes.

I had the same issue and realized that removing the parentheses worked. Sometimes having someone else read your code can be useful if you have been the only one working on it for some time.

E.g.

  cmd.CommandType = CommandType.Text(); 

Replace: cmd.CommandType = CommandType.Text;

The answer by @hybrid is quite informative, except it doesn't explain the purpose as mentioned by @ashitaka "What if you use the Mobile First approach? So, we have the mobile CSS first and then use min-width to target larger sites. We shouldn't use the only keyword in that context, right? "

Want to add in here that the purpose is simply to prevent non supporting browsers to use that Other device style as if it starts from "screen" without it will take it for a screen whereas if it starts from "only" style will be ignored.

Answering to ashitaka consider this example

<link rel="stylesheet" type="text/css" 
  href="android.css" media="only screen and (max-width: 480px)" />
<link rel="stylesheet" type="text/css" 
  href="desktop.css" media="screen and (min-width: 481px)" />

If we don't use "only" it will still work as desktop-style will also be used striking android styles but with unnecessary overhead. In this case, IF a browser is non-supporting it will fallback to the second Style-sheet ignoring the first.

Since you didn't refer to self in the bar method body, PyCharm is asking if you might have wanted to make bar static. In other programming languages, like Java, there are obvious reasons for declaring a static method. In Python, the only real benefit to a static method (AFIK) is being able to call it without an instance of the class. However, if that's your only reason, you're probably better off going with a top-level function - as note here.

In short, I'm not one hundred percent sure why it's there. I'm guessing they'll probably remove it in an upcoming release.

You can't do it using environment variables directly. You need to use the set of "non standard" options that are passed to the java command. Run: java -X for details. The options you're looking for are -Xmx and -Xms (this is "initial" heap size, so probably what you're looking for.)

Some products like Ant or Tomcat might come with a batch script that looks for the JAVA_OPTS environment variable, but it's not part of the Java runtime. If you are using one of those products, you may be able to set the variable like:

set JAVA_OPTS="-Xms128m -Xmx256m"  

You can also take this approach with your own command line like:

set JAVA_OPTS="-Xms128m -Xmx256m"  
java ${JAVA_OPTS} MyClass

This does it for folder names:

def printFolderName(init_indent, rootFolder):
    fname = rootFolder.split(os.sep)[-1]
    root_levels = rootFolder.count(os.sep)
    # os.walk treats dirs breadth-first, but files depth-first (go figure)
    for root, dirs, files in os.walk(rootFolder):
        # print the directories below the root
        levels = root.count(os.sep) - root_levels
        indent = ' '*(levels*2)
        print init_indent + indent + root.split(os.sep)[-1]

As long as your file has consistent formatting (i.e. line-breaks), this is easy with just basic file IO and string operations:

with open('my_file.txt', 'rU') as in_file:
    data = in_file.read().split('\n')

That will store your data file as a list of items, one per line. To then put it into a file, you would do the opposite:

with open('new_file.txt', 'w') as out_file:
    out_file.write('\n'.join(data)) # This will create a string with all of the items in data separated by new-line characters

Hopefully that fits what you're looking for.

I got this error while installing awscli on Windows 10 in anaconda (python 3.7). While troubleshooting, I went to the answer https://stackoverflow.com/a/49991357/6862405 and then to https://stackoverflow.com/a/54582701/6862405. Finally found that I need to install the libraries PyOpenSSL, cryptography, enum34, idna and ipaddress. After installing these (using simply pip install command), I was able to install awscli.

Note that the Perldebugger can also be invoked from the scripts shebang line, which is how I mostly use the -x flag you refer to, to debug shell scripts.

#! /usr/bin/perl -d

I have made a Windows command line tool that do just that.

You can download it here: http://commandline.dk/csv2ddl.htm

Usage:

C:\Temp>csv2ddl.exe mysql test.csv test.sql

Or

C:\Temp>csv2ddl.exe mysql advanced doublequote comma test.csv test.sql

You'll want to check your docs for your version of gcc & ld:

However for me (OS X gcc 4.0.1) I find these for ld

-dead_strip

Remove functions and data that are unreachable by the entry point or exported symbols.

-dead_strip_dylibs

Remove dylibs that are unreachable by the entry point or exported symbols. That is, suppresses the generation of load command commands for dylibs which supplied no symbols during the link. This option should not be used when linking against a dylib which is required at runtime for some indirect reason such as the dylib has an important initializer.

And this helpful option

-why_live symbol_name

Logs a chain of references to symbol_name. Only applicable with -dead_strip. It can help debug why something that you think should be dead strip removed is not removed.

There's also a note in the gcc/g++ man that certain kinds of dead code elimination are only performed if optimization is enabled when compiling.

While these options/conditions may not hold for your compiler, I suggest you look for something similar in your docs.

$time = strtotime(date('2016-02-03 12:00:00'));
        echo date("H:i:s",strtotime("-30 minutes", $time));

It's just one of those language design choices. On some level they are justified. They make it so you need to go pretty far out of your way to try and call the method, and if you really need it that badly, you must have a pretty good reason!

Debugging hooks and testing come to mind as possible applications, used responsibly of course.

If your table is only 2 columns across, you can easily reach the second td with the adjacent sibling selector, which IE8 does support along with :first-child:

.editor td:first-child
{
    width: 150px; 
}

.editor td:first-child + td input,
.editor td:first-child + td textarea
{
    width: 500px;
    padding: 3px 5px 5px 5px;
    border: 1px solid #CCC; 
}

Otherwise, you'll have to use a JS selector library like jQuery, or manually add a class to the last td, as suggested by James Allardice.

Or, using your EOF markers, you need to quote the initial marker so expansion won't be done:

#-----v---v------
cat <<'EOF' >> brightup.sh
#!/bin/bash
curr=`cat /sys/class/backlight/intel_backlight/actual_brightness`
if [ $curr -lt 4477 ]; then
   curr=$((curr+406));
   echo $curr  > /sys/class/backlight/intel_backlight/brightness;
fi
EOF

IHTH

Ok, finally found the solution.

Probably due to lack of experience with ReactJS and web development...

    var Task = React.createClass({
    render: function() {
      var percentage = this.props.children + '%';
      ....
        <div className="ui-progressbar-value ui-widget-header ui-corner-left" style={{width : percentage}}/>
      ...

I created the percentage variable outside in the render function.

If you want to use a phenomenical (with a formula in it) blank cell to make an arithmetic/mathematical operation, all you have to do is use this formula:

=N(C1)

assuming C1 is a "blank" cell

Swift 3

This worked for me (referring to set tabBarItems image colors):

UITabBar.appearance().tintColor = ThemeColor.Blue

if let items = tabBarController.tabBar.items {
        let tabBarImages = getTabBarImages() // tabBarImages: [UIImage]
        for i in 0..<items.count {
            let tabBarItem = items[i]
            let tabBarImage = tabBarImages[i]
            tabBarItem.image = tabBarImage.withRenderingMode(.alwaysOriginal)
            tabBarItem.selectedImage = tabBarImage
        }
    }

I have noticed that if you set image with rendering mode = .alwaysOriginal, the UITabBar.tintColor doesn't have any effect.

I am assuming that current_article_url is http://0.0.0.0:4567/link_to_title

<td class="first"> <?php echo $proxy ?> </td> is inside a literal string that you are echoing. End the string, or concatenate it correctly:

<td class="first">' . $proxy . '</td>

You are simply reducing the values from a number. So substracting 6 from 3 (date) will return -3 only.

You need to individually add/remove unit of time in date object

var date = new Date();
date.setDate( date.getDate() - 6 );
date.setFullYear( date.getFullYear() - 1 );
$("#searchDateFrom").val((date.getMonth() ) + '/' + (date.getDate()) + '/' + (date.getFullYear()));

To create a new empty column and fill it with the same value (here 100) for every row (in Toad for Oracle):

ALTER TABLE my_table ADD new_column INT;
UPDATE my_table SET new_column = 100;

You could use the substr function please check following example,

$string1 = "tarunmodi";
$first4 = substr($string1, 4);
echo $first4;

Output: nmodi

I have this to simply rename all files in subfolders of folder

import os

def replace(fpath, old_str, new_str):
    for path, subdirs, files in os.walk(fpath):
        for name in files:
            if(old_str.lower() in name.lower()):
                os.rename(os.path.join(path,name), os.path.join(path,
                                            name.lower().replace(old_str,new_str)))

I am replacing all occurences of old_str with any case by new_str.

You need to put the last() indexing on the nodelist result, rather than as part of the selection criteria. Try:

(//element[@name='D'])[last()]

The problem is that Properties implements Map<Object, Object>, whereas the HashMap constructor expects a Map<? extends String, ? extends String>.

This answer explains this (quite counter-intuitive) decision. In short: before Java 5, Properties implemented Map (as there were no generics back then). This meant that you could put any Object in a Properties object. This is still in the documenation:

Because Properties inherits from Hashtable, the put and putAll methods can be applied to a Properties object. Their use is strongly discouraged as they allow the caller to insert entries whose keys or values are not Strings. The setProperty method should be used instead.

To maintain compatibility with this, the designers had no other choice but to make it inherit Map<Object, Object> in Java 5. It's an unfortunate result of the strive for full backwards compatibility which makes new code unnecessarily convoluted.

If you only ever use string properties in your Properties object, you should be able to get away with an unchecked cast in your constructor:

Map<String, String> map = new HashMap<String, String>( (Map<String, String>) properties);

or without any copies:

Map<String, String> map = (Map<String, String>) properties;

If you want to see data updates you could use this technique with required permissions:

SELECT OBJECT_NAME(OBJECT_ID) AS DatabaseName, last_user_update,*
FROM sys.dm_db_index_usage_stats
WHERE database_id = DB_ID( 'DATABASE')
AND OBJECT_ID=OBJECT_ID('TABLE')

Concept explained

Are you trying do a cross-domain AJAX call? Meaning, your service is not hosted in your same web application path? Your web-service must support method injection in order to do JSONP.

Your code seems fine and it should work if your web services and your web application hosted in the same domain.

When you do a $.ajax with dataType: 'jsonp' meaning that jQuery is actually adding a new parameter to the query URL.

For instance, if your URL is http://10.211.2.219:8080/SampleWebService/sample.do then jQuery will add ?callback={some_random_dynamically_generated_method}.

This method is more kind of a proxy actually attached in window object. This is nothing specific but does look something like this:

window.some_random_dynamically_generated_method = function(actualJsonpData) {
    //here actually has reference to the success function mentioned with $.ajax
    //so it just calls the success method like this: 
    successCallback(actualJsonData);
}

Summary

Your client code seems just fine. However, you have to modify your server-code to wrap your JSON data with a function name that passed with query string. i.e.

If you have reqested with query string

?callback=my_callback_method

then, your server must response data wrapped like this:

my_callback_method({your json serialized data});

You must build an executable file before you can run it. So if you don't “BUILD” your file, then it will not be able to link and load that object file, and hence it does not have the required binary numbers to execute.

So basically right click on the Project -> Build Project -> Run As Local C/C++ Application should do the trick

Update:

MongoServer.Create is obsolete now (thanks to @aknuds1). Instead this use following code:

var _server = new MongoClient(connectionString).GetServer();

It's easy. You should first take database name from connection string and then get database by name. Complete example:

var connectionString = "mongodb://localhost:27020/mydb";

//take database name from connection string
var _databaseName = MongoUrl.Create(connectionString).DatabaseName;
var _server = MongoServer.Create(connectionString);

//and then get database by database name:
_server.GetDatabase(_databaseName);

Important: If your database and auth database are different, you can add a authSource= query parameter to specify a different auth database. (thank you to @chrisdrobison)

From docs:

NOTE If you are using the database segment as the initial database to use, but the username and password specified are defined in a different database, you can use the authSource option to specify the database in which the credential is defined. For example, mongodb://user:pass@hostname/db1?authSource=userDb would authenticate the credential against the userDb database instead of db1.

You can try this in round_tv.xml in drawable folder:

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

    <stroke android:color="#22ff55" android:width="3dip"/>

    <corners
        android:bottomLeftRadius="30dp"
        android:bottomRightRadius="30dp"
        android:topLeftRadius="30dp"
        android:topRightRadius="30dp" />

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

</shape>

Apply that drawable in your textviews as:

<TextView
    android:id="@+id/tv"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/round_tv"
    android:gravity="center_vertical|center_horizontal"
    android:text="ddd"
    android:textColor="#000"
    android:textSize="20sp" />

Output:

Hope this helps.

Edit: If your text is too long, Oval shape is more preferred.

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

    <stroke android:color="#55ff55" android:width="3dip"/>

    <corners
        android:bottomLeftRadius="30dp"
        android:bottomRightRadius="30dp"
        android:topLeftRadius="30dp"
        android:topRightRadius="30dp" />

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

</shape>

Output:

If you still need it a proper circle, then I guess you will need to set its height dynamically after setting text in it, new height should be as much as its new width so as to make a proper circle.

UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];

Happy coding !!!

i had a same issue because of my Nvidea Graphics card Driver Problem.

If your System has Dedicated Graphics card then Check for the latest Driver and Install it.

Other wise simply Choose Emulated Performance as Software in Emulator Configurations

After Updating the driver the issue is resolved :)

I have some hacky answers that are likely to be terrible... but I have very little experience at this point.

a way:

class myClass():
    myInstances = []
    def __init__(self, myStr01, myStr02):
        self.myStr01 = myStr01
        self.myStr02 = myStr02
        self.__class__.myInstances.append(self)

myObj01 = myClass("Foo", "Bar")
myObj02 = myClass("FooBar",  "Baz")

for thisObj in myClass.myInstances:
    print(thisObj.myStr01)
    print(thisObj.myStr02)

A hack way to get this done:

import sys
class myClass():
    def __init__(self, myStr01, myStr02):
        self.myStr01 = myStr01
        self.myStr02 = myStr02

myObj01 = myClass("Foo", "Bar")
myObj02 = myClass("FooBar",  "Baz")

myInstances = []
myLocals = str(locals()).split("'")
thisStep = 0
for thisLocalsLine in myLocals:
    thisStep += 1
    if "myClass object at" in thisLocalsLine:
        print(thisLocalsLine)
        print(myLocals[(thisStep - 2)])
        #myInstances.append(myLocals[(thisStep - 2)])
        print(myInstances)
        myInstances.append(getattr(sys.modules[__name__], myLocals[(thisStep - 2)]))

for thisObj in myInstances:
    print(thisObj.myStr01)
    print(thisObj.myStr02)

Another more 'clever' hack:

import sys
class myClass():
    def __init__(self, myStr01, myStr02):
        self.myStr01 = myStr01
        self.myStr02 = myStr02

myInstances = []
myClasses = {
    "myObj01": ["Foo", "Bar"],
    "myObj02": ["FooBar",  "Baz"]
    }

for thisClass in myClasses.keys():
    exec("%s = myClass('%s', '%s')" % (thisClass, myClasses[thisClass][0], myClasses[thisClass][1]))
    myInstances.append(getattr(sys.modules[__name__], thisClass))

for thisObj in myInstances:
    print(thisObj.myStr01)
    print(thisObj.myStr02)

Bracket notation can use variables, so it is useful in two instances where dot notation will not work:

1) When the property names are dynamically determined (when the exact names are not known until runtime).

2) When using a for..in loop to go through all the properties of an object.

source: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Working_with_Objects

A frequent source of these bugs is when you have a method that accepts a reference or pointer to an object but leaves ownership unclear. Style and commenting conventions can make this less likely.

Let the case where the function takes ownership of the object be the special case. In all situations where this happens, be sure to write a comment next to the function in the header file indicating this. You should strive to make sure that in most cases the module or class which allocates an object is also responsible for deallocating it.

Using const can help a lot in some cases. If a function will not modify an object, and does not store a reference to it that persists after it returns, accept a const reference. From reading the caller's code it will be obvious that your function has not accepted ownership of the object. You could have had the same function accept a non-const pointer, and the caller may or may not have assumed that the callee accepted ownership, but with a const reference there's no question.

Do not use non-const references in argument lists. It is very unclear when reading the caller code that the callee may have kept a reference to the parameter.

I disagree with the comments recommending reference counted pointers. This usually works fine, but when you have a bug and it doesn't work, especially if your destructor does something non-trivial, such as in a multithreaded program. Definitely try to adjust your design to not need reference counting if it's not too hard.

Just Paste This Code In Starting to The Top of Page.

<?php
header("Content-Type: text/html; charset=ISO-8859-1");
?>

@STEVER's answer is satisfactory. However, I thought it may be useful to post a slightly different approach. I use a method called isValue which returns true for all values except null, undefined, NaN, and Infinity. Lumping in NaN with null and undefined is the real benefit of the function for me. Lumping Infinity in with null and undefined is more debatable, but frankly not that interesting for my code because I practically never use Infinity.

The following code is inspired by Y.Lang.isValue. Here is the source for Y.Lang.isValue.

/**
 * A convenience method for detecting a legitimate non-null value.
 * Returns false for null/undefined/NaN/Infinity, true for other values,
 * including 0/false/''
 * @method isValue
 * @static
 * @param o The item to test.
 * @return {boolean} true if it is not null/undefined/NaN || false.
 */
angular.isValue = function(val) {
  return !(val === null || !angular.isDefined(val) || (angular.isNumber(val) && !isFinite(val)));
};

Or as part of a factory

.factory('lang', function () {
  return {
    /**
     * A convenience method for detecting a legitimate non-null value.
     * Returns false for null/undefined/NaN/Infinity, true for other values,
     * including 0/false/''
     * @method isValue
     * @static
     * @param o The item to test.
     * @return {boolean} true if it is not null/undefined/NaN || false.
     */
    isValue: function(val) {
      return !(val === null || !angular.isDefined(val) || (angular.isNumber(val) && !isFinite(val)));
  };
})

if you use mvvm and your itemssource is located in your vm. just call INotifyPropertyChanged for your collection property when you want to refresh.

OnPropertyChanged("YourCollectionProperty");

This should help. Its CSS3 :first-child where you should say that the first tr of the table you would like to style. http://reference.sitepoint.com/css/pseudoclass-firstchild

As Obama says "Yes We Can". Here is the link to it. developers.google.com/#jquery

You need to use

Google

ajax.googleapis.com/ajax/libs/jqueryui/[VERSION NO]/jquery-ui.min.js
ajax.googleapis.com/ajax/libs/jqueryui/[VERSION NO]/themes/[THEME NAME]/jquery-ui.min.css

jQuery CDN

Find theme names here http://jqueryui.com/themeroller/ in gallery subtab

.

But i would not recommend you hosting from cdn for the following reasons

1. Although your chance of hit rate is good in case of Google CDN compared to others but it's still abysmally low.(any cdn not just google).
2. Loading via cdn you will have 3 requests one for jQuery.js, one for jQueryUI.js and one for your code. You might as will compress it on your local and load it as one single resource.

For one comparable

# Throws ValueError if nothing is found
some_list = ['foo', 'bar', 'baz'].index('baz')
# some_list == 2

Custom predicate

some_list = [item1, item2, item3]

# Throws StopIteration if nothing is found
# *unless* you provide a second parameter to `next`
index_of_value_you_like = next(
    i for i, item in enumerate(some_list)
    if item.matches_your_criteria())

Finding index of all items by predicate

index_of_staff_members = [
    i for i, user in enumerate(users)
    if user.is_staff()]

I don't think reinstalling SQL Server is going to fix this, it's just going to kill some time.

1. Confirm that your user account has read privileges to the folder in question.
2. Use a tool like Process Monitor to see what user is actually trying to access the file.

3. My guess is that it is not Michael-PC\Michael that is trying to access the file, but rather the SQL Server service account. If this is the case, then you have at least three options (but probably others):

   a. Set the SQL Server service to run as you.
   b. Grant the SQL Server service account explicit access to that folder.
   c. Put the files somewhere more logical where SQL Server has access, or can be made to have access (e.g. C:\bulk\).

I suggest these things assuming that this is a contained, local workstation. There are definitely more serious security concerns around local filesystem access from SQL Server when we're talking about a production machine, of course this can still be largely mitigated by using c. above - and only giving the service account access to the folders you want it to be able to touch.

For others with the same problem on iOS with CocoaPods:

I tried all of the solutions above, without luck. I have some packages with native dependencies in my project, and some of those needed pod modules being installed. The problem was that React was specified in my Podfile, but the React pod didn't automatically get upgraded by using react-native-git-upgrade.

The fix is to upgrade all installed pods, by running cd ios && pod install.

<div class="scrollingDiv">foo</div>

If one really wanted to they could make there own version of scanf() like so:

    import java.util.ArrayList;
    import java.util.Scanner;

public class Testies {

public static void main(String[] args) {
    ArrayList<Integer> nums = new ArrayList<Integer>();
    ArrayList<String> strings = new ArrayList<String>();

    // get input
    System.out.println("Give me input:");
    scanf(strings, nums);

    System.out.println("Ints gathered:");
    // print numbers scanned in
    for(Integer num : nums){
        System.out.print(num + " ");
    }
    System.out.println("\nStrings gathered:");
    // print strings scanned in
    for(String str : strings){
        System.out.print(str + " ");
    }

    System.out.println("\nData:");
    for(int i=0; i<strings.size(); i++){
        System.out.println(nums.get(i) + " " + strings.get(i));
    }
}

// get line from system
public static void scanf(ArrayList<String> strings, ArrayList<Integer> nums){
    Scanner getLine = new Scanner(System.in);
    Scanner input = new Scanner(getLine.nextLine());

    while(input.hasNext()){
        // get integers
        if(input.hasNextInt()){
            nums.add(input.nextInt());
        }
        // get strings
        else if(input.hasNext()){
            strings.add(input.next());
        }
    }
}

// pass it a string for input
public static void scanf(String in, ArrayList<String> strings, ArrayList<Integer> nums){
    Scanner input = (new Scanner(in));

    while(input.hasNext()){
        // get integers
        if(input.hasNextInt()){
            nums.add(input.nextInt());
        }
        // get strings
        else if(input.hasNext()){
            strings.add(input.next());
        }
    }
}


}

Obviously my methods only check for Strings and Integers, if you want different data types to be processed add the appropriate arraylists and checks for them. Also, hasNext() should probably be at the bottom of the if-else if sequence since hasNext() will return true for all of the data in the string.

Output:

Give me input: apples 8 9 pears oranges 5 Ints gathered: 8 9 5 Strings gathered: apples pears oranges Data: 8 apples 9 pears 5 oranges

Probably not the best example; but, the point is that Scanner implements the Iterator class. Making it easy to iterate through the scanners input using the hasNext<datatypehere>() methods; and then storing the input.

Try the following:

JS file

this.options = { 
        languages: [{language: 'English', lg:'en'}, {language:'German', lg:'de'}]
};
console.log(signinDetails.language);

You can also use isa() to check if a variable is of a particular type. If you want to be even more specific, you can use ischar(), isfloat(), iscell(), etc.

You can do something like this:

Using search will return a SRE_match object, if it matches your search string.

>>> import re
>>> m = re.search(u'ba[r|z|d]', 'bar')
>>> m
<_sre.SRE_Match object at 0x02027288>
>>> m.group()
'bar'
>>> n = re.search(u'ba[r|z|d]', 'bas')
>>> n.group()

If not, it will return None

Traceback (most recent call last):
  File "<pyshell#17>", line 1, in <module>
    n.group()
AttributeError: 'NoneType' object has no attribute 'group'

And just to print it to demonstrate again:

>>> print n
None

Change

vote = input('Enter the name of the player you wish to vote for')

to

vote = int(input('Enter the name of the player you wish to vote for'))

You are getting the input from the console as a string, so you must cast that input string to an int object in order to do numerical operations.

as mentioned above: its not possible to call a css pseudo-class / -element inline. what i now did, is: give your element a unique identifier, f.ex. an id or a unique class. and write a fitting <style> element

<style>#id29:before { content: "*";}</style>
<article id="id29">
  <!-- something -->
</article>

fugly, but what inline css isnt..?

If you have more than one join you could use comma separated USING statements:

DELETE 
FROM 
      AAA AS a 
USING 
      BBB AS b,
      CCC AS c
WHERE 
      a.id = b.id 
  AND a.id = c.id
  AND a.uid = 12345 
  AND c.gid = 's434sd4'

Reference

Another way is to use function expr with where clause

import org.apache.spark.sql.functions.expr

df2 = df1.where(expr("col1 = 'value1' and col2 = 'value2'"))

It works the same.

For future Googlers, If you get an error similar below after you trigger click for a polygon

"Uncaught TypeError: Cannot read property 'vertex' of undefined"

then try the code below

google.maps.event.trigger(polygon, "click", {});

Serial sends data 8 bits at a time, that translates to 1 byte and 1 byte means 1 character.

You need to implement your own method that can read characters into a buffer until some sentinel is reached. The convention is to send a message like 12431\n indicating one line.

So what you need to do is to implement a buffer that will store X number of characters and as soon as you reach that \n, perform your operation on the line and proceed to read the next line into the buffer.

Note you will have to take care of buffer overflow cases i.e. when a line is received that is longer than your buffer etc...

EDIT

import serial

ser = serial.Serial(
    port='COM5',\

print("connected to: " + ser.portstr)

#this will store the line

            line = []
            break

In 1985, individuals from companies throughout the computer industry joined together to develop the POSIX (Portable Operating System Interface for Computer Environments) standard, which is based largely on the UNIX System V Interface Definition (SVID) and other earlier standardization efforts. These efforts were spurred by the U.S. government, which needed a standard computing environment to minimize its training and procurement costs. Released in 1988, POSIX is a group of IEEE standards that define the API, shell, and utility interfaces for an operating system. Although aimed at UNIX-like systems, the standards can apply to any compatible operating system. Now that these stan- dards have gained acceptance, software developers are able to develop applications that run on all conforming versions of UNIX, Linux, and other operating systems.

For array of integer type, we need to change it to string type first and than use join function to get clean output without brackets.

    arr = [1, 2, 3, 4, 5]    
    print(', '.join(map(str, arr)))

OUTPUT - 1, 2, 3, 4, 5

For array of string type, we need to use join function directly to get clean output without brackets.

    arr = ["Ram", "Mohan", "Shyam", "Dilip", "Sohan"]
    print(', '.join(arr)

OUTPUT - Ram, Mohan, Shyam, Dilip, Sohan

With Intellij Toggle Skip Test Mode can be used from Maven Projects tab:

Try using Ctrl-click on the multiple places you want the cursors. Ctrl-D is for multiple incremental finds.

The easiest way is to use history.go(-1);

Try this:

<a href="#" onclick="history.go(-1)">Go Back</a>

Instead of wading through the description of all the options, you can jump to 3.4.3 Short Options Cross Reference under the info tar command.

x means --extract. v means --verbose. f means --file. z means --gzip. You can combine one-letter arguments together, and f takes an argument, the filename. There is something you have to watch out for:

Short options' letters may be clumped together, but you are not required to do this (as compared to old options; see below). When short options are clumped as a set, use one (single) dash for them all, e.g., ''tar' -cvf'. Only the last option in such a set is allowed to have an argument(1).

---

This old way of writing 'tar' options can surprise even experienced users. For example, the two commands:

 tar cfz archive.tar.gz file
 tar -cfz archive.tar.gz file

are quite different. The first example uses 'archive.tar.gz' as the value for option 'f' and recognizes the option 'z'. The second example, however, uses 'z' as the value for option 'f' -- probably not what was intended.

How to change the UINavigationController back button name?

set title text to string with one blank space as below

title = " "

Don't have enough reputation to add comments :)

Try the following:

T[] r1 = new T[size1];
T[] r2 = new T[size2];

List<T> targetList = new List<T>(r1);
targetList.Concat(r2);
T[] targetArray = targetList.ToArray();

SendKeys is straight, but you may dislike it (e.g. it opens the Immediate window if it was closed, and moves the focus).

The WinAPI + VBE way is really elaborate, but you may wish not to grant VBA access to VBE (might even be your company group policy not to).

Instead of clearing you can flush its content (or part of it...) away with blanks:

Debug.Print String(65535, vbCr)

Unfortunately, this only works if the caret position is at the end of the Immediate window (string is inserted, not appended). If you only post content via Debug.Print and don't use the window interactively, this will do the job. If you actively use the window and occasionally navigate to within the content, this does not help a lot.

Well, my solution uses residue technique. We can place the values under sorting in the upper 2 bytes and the indices of the elements - in the lower 2 bytes:

int myints[] = {32,71,12,45,26,80,53,33};

for (int i = 0; i < 8; i++)
   myints[i] = myints[i]*(1 << 16) + i;

Then sort the array myints as usual:

std::vector<int> myvector(myints, myints+8);
sort(myvector.begin(), myvector.begin()+8, std::less<int>());

After that you can access the elements' indices via residuum. The following code prints the indices of the values sorted in the ascending order:

for (std::vector<int>::iterator it = myvector.begin(); it != myvector.end(); ++it)
   std::cout << ' ' << (*it)%(1 << 16);

Of course, this technique works only for the relatively small values in the original array myints (i.e. those which can fit into upper 2 bytes of int). But it has additional benefit of distinguishing identical values of myints: their indices will be printed in the right order.

Use the new CSS viewport units vw and vh (viewport width / viewport height)

Also, browser support is pretty good too: IE9+, FF, Chrome, Safari- caniuse

use ONLY

function init() { 
    about = document.getElementById("about");
    about.style.color = 'blue';
}

.innerHTML() sets or gets the HTML syntax describing the element's descendants., All you need is an object here.

Demo

I have found out when running a PS1 file for a Mapped drive to Dropbox that I'm always getting this error. When opening up properties for the PS1 there is no "Unblock".

The only thing that work for me is

powershell.exe -executionpolicy bypass -file .\Script.ps1

If you have GNU awk this is the solution you want:

$ awk '{print $1}' FPAT='"[^"]+"' file
"A B"
"C"
"D"

$('#form').keydown(function(e){
    if (e.keyCode === 13) { // If Enter key pressed
        $(this).trigger('submit');
    }
});

Although answers here are sufficient, I really think W3Schools example on this issue is very straightforward (it cleared up the confusion (for me) right away).

Use the :hover selector to change the style of a button when you move the mouse over it.

Tip: Use the transition-duration property to determine the speed of the "hover" effect:

Example

.button {
    -webkit-transition-duration: 0.4s; /* Safari & Chrome */
    transition-duration: 0.4s;
}

.button:hover {
    background-color: #4CAF50; /* Green */
    color: white;
}

In summary, for transitions where you want the "enter" and "exit" animations to be the same, you need to employ transitions on the main selector .button rather than the hover selector .button:hover. For transitions where you want the "enter" and "exit" animations to be different, you will need specify different main selector and hover selector transitions.

Yes, you can merge them using HTML. When I create tables in .md files from Github, I always like to use HTML code instead of markdown.

Github Flavored Markdown supports basic HTML in .md file. So this would be the answer:

Markdown mixed with HTML:

| Tables        | Are           | Cool  |
| ------------- |:-------------:| -----:|
| col 3 is      | right-aligned | $1600 |
| col 2 is      | centered      |   $12 |
| zebra stripes | are neat      |    $1 |
| <ul><li>item1</li><li>item2</li></ul>| See the list | from the first column|

Or pure HTML:

<table>
  <tbody>
    <tr>
      <th>Tables</th>
      <th align="center">Are</th>
      <th align="right">Cool</th>
    </tr>
    <tr>
      <td>col 3 is</td>
      <td align="center">right-aligned</td>
      <td align="right">$1600</td>
    </tr>
    <tr>
      <td>col 2 is</td>
      <td align="center">centered</td>
      <td align="right">$12</td>
    </tr>
    <tr>
      <td>zebra stripes</td>
      <td align="center">are neat</td>
      <td align="right">$1</td>
    </tr>
    <tr>
      <td>
        <ul>
          <li>item1</li>
          <li>item2</li>
        </ul>
      </td>
      <td align="center">See the list</td>
      <td align="right">from the first column</td>
    </tr>
  </tbody>

This is how it looks on Github:

You can use Boolean / boolean. Simplicity is the way to go. If you do not need specific api (Collections, Streams, etc.) and you are not foreseeing that you will need them - use primitive version of it (boolean).

1. With primitives you guarantee that you will not pass null values.
   You will not fall in traps like this. The code below throws NullPointerException (from: Booleans, conditional operators and autoboxing):

   public static void main(String[] args) throws Exception { Boolean b = true ? returnsNull() : false; // NPE on this line. System.out.println(b); } public static Boolean returnsNull() { return null; }

2. Use Boolean when you need an object, eg:

   • Stream of Booleans,
   • Optional
   • Collections of Booleans

To download file on flask call. File name is Examples.pdf When I am hitting 127.0.0.1:5000/download it should get download.

Example:

from flask import Flask
from flask import send_file
app = Flask(__name__)

@app.route('/download')
def downloadFile ():
    #For windows you need to use drive name [ex: F:/Example.pdf]
    path = "/Examples.pdf"
    return send_file(path, as_attachment=True)

if __name__ == '__main__':
    app.run(port=5000,debug=True) 

You put your template in the wrong place. From the Flask docs:

Flask will look for templates in the templates folder. So if your application is a module, this folder is next to that module, if it’s a package it’s actually inside your package: See the docs for more information: http://flask.pocoo.org/docs/quickstart/#rendering-templates

Without wanting to give you the answer here is the logic.

You have 2 possible values in each digit. you have 9 of them.

like in base 10 where you have 10 different values by digit say you have 2 of them (which makes from 0 to 99) : 0 to 99 makes 100 numbers. if you do the calcul you have an exponential function

base^numberOfDigits:
10^2 = 100 ;
2^9 = 512

1. With Mongoose (and Node), this worked:

   • User.find({ email: /^[email protected]$/i })

   • User.find({ email: new RegExp(`^${emailVariable}$`, 'i') })

2. In MongoDB, this worked:

   • db.users.find({ email: { $regex: /^[email protected]$/i }})

Both lines are case-insensitive. The email in the DB could be [email protected] and both lines will still find the object in the DB.

Likewise, we could use /^[email protected]$/i and it would still find email: [email protected] in the DB.

 DATE_ADD(FROM_DATE_HERE, INTERVAL INTERVAL_TIME_HERE DAY) 

will give the Date after adjusting the INTERVAL

eg.

DATE_ADD(NOW(), INTERVAL -1 DAY) for deducting 1 DAY from current Day
DATE_ADD(NOW(), INTERVAL 2 DAY)  for adding 2 Days

You can use like

UPDATE classes WHERE date=(DATE_ADD(date, INTERVAL 1 DAY)) WHERE id=161

//C# class

public class DashBoardViewModel 
{
    public int Id { get; set;} 
    public decimal TotalSales { get; set;} 
    public string Url { get; set;} 
     public string MyDate{ get; set;} 
}

//JavaScript file
//Create dashboard.js file
$(document).ready(function () {

    // See the html on the View below
    $('.dashboardUrl').on('click', function(){
        var url = $(this).attr("href"); 
    });

    $("#inpDateCompleted").change(function () {   

        // Construct your view model to send to the controller
        // Pass viewModel to ajax function 

        // Date
        var myDate = $('.myDate').val();

        // IF YOU USE @Html.EditorFor(), the myDate is as below
        var myDate = $('#MyDate').val();
        var viewModel = { Id : 1, TotalSales: 50, Url: url, MyDate: myDate };


        $.ajax({
            type: 'GET',
            dataType: 'json',
            cache: false,
            url: '/Dashboard/IndexPartial',
            data: viewModel ,
            success: function (data, textStatus, jqXHR) {
                //Do Stuff 
                $("#DailyInvoiceItems").html(data.Id);
            },
            error: function (jqXHR, textStatus, errorThrown) {
                //Do Stuff or Nothing
            }
        });

    });
});

//ASP.NET 5 MVC 6 Controller
public class DashboardController {

    [HttpGet]
    public IActionResult IndexPartial(DashBoardViewModel viewModel )
    {
        // Do stuff with my model
        var model = new DashBoardViewModel {  Id = 23 /* Some more results here*/ };
        return Json(model);
    }
}

// MVC View 
// Include jQuerylibrary

// If you want to capture your URL dynamically

    <a class="dashboardUrl" href ="@Url.Action("IndexPartial","Dashboard")"> LinkText </a>
</div>
<div>
    <input class="myDate" type="text"/>
//OR
   @Html.EditorFor(model => model.MyDate) 
</div>

Try converting your procedure in to an Inline Function which returns a table as follows:

CREATE FUNCTION MyProc()
RETURNS TABLE AS
RETURN (SELECT * FROM MyTable)

And then you can call it as

SELECT * FROM MyProc()

You also have the option of passing parameters to the function as follows:

CREATE FUNCTION FuncName (@para1 para1_type, @para2 para2_type , ... ) 

And call it

SELECT * FROM FuncName ( @para1 , @para2 )

Yet another reason happened in my case, because of using async/await, resulting in the same error message:

System.InvalidOperationException: 'Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.'

Just a quick overview of what happened (and how I resolved it), hopefully this will help others in the future:

Finding the cause

This all happened in an ASP.NET Core 3.1 web project with Dapper and SQL Server, but I do think it is independent of that very kind of project.

First, I have a central function to get me SQL connections:

internal async Task<DbConnection> GetConnection()
{
    var r = new SqlConnection(GetConnectionString());
    await r.OpenAsync().ConfigureAwait(false);
    return r;
}

I'm using this function in dozens of methods like e.g. this one:

public async Task<List<EmployeeDbModel>> GetAll()
{
    await using var conn = await GetConnection();
    var sql = @"SELECT * FROM Employee";

    var result = await conn.QueryAsync<EmployeeDbModel>(sql);
    return result.ToList();
}

As you can see, I'm using the new using statement without the curly braces ({, }), so disposal of the connection is done at the end of the function.

Still, I got the error about no more connections in the pool being available.

I started debugging my application and let it halt upon the exception happening. When it halted, I first did a look at the Call Stack window, but this only showed some location inside System.Data.SqlClient, and was no real help to me:

Next, I took a look at the Tasks window, which was of a much better help:

There were literally thousands of calls to my own GetConnection method in an "Awaiting" or "Scheduled" state.

When double-clicking such a line in the Tasks window, it showed me the related location in my code via the Call Stack window.

This helped my to find out the real reason of this behaviour. It was in the below code (just for completeness):

[Route(nameof(LoadEmployees))]
public async Task<IActionResult> LoadEmployees(
    DataSourceLoadOptions loadOption)
{
    var data = await CentralDbRepository.EmployeeRepository.GetAll();

    var list =
        data.Select(async d =>
            {
                var values = await CentralDbRepository.EmployeeRepository.GetAllValuesForEmployee(d);
                return await d.ConvertToListItemViewModel(
                    values,
                    Config,
                    CentralDbRepository);
            })
            .ToListAsync();
    return Json(DataSourceLoader.Load(await list, loadOption));
}

In the above controller action, I first did a call to EmployeeRepository.GetAll() to get a list of models from the database table "Employee".

Then, for each of the returned models (i.e. for each row of the result set), I did again do a database call to EmployeeRepository.GetAllValuesForEmployee(d).

While this is very bad in terms of performance anyway, in an async context it behaves in a way, that it is eating up connection pool connections without releasing them appropriately.

Solution

I resolved it by removing the SQL query in the inner loop of the outer SQL query.

This should be done by either completely omitting it, or if required, move it to one/multilpe JOINs in the outer SQL query to get all data from the database in one single SQL query.

tl;dr / lessons learned

Don't do lots of SQL queries in a short amount of time, especially when using async/await.

!!! KIVY !!!

I was amazed seeing that no one mentioned Kivy!!!

I have once done a project using Tkinter, although they do advocate that it has improved a lot, it still gives me a feel of windows 98, so I switched to Kivy.

I have been following a tutorial series if it helps...

Just to give an idea of how kivy looks, see this (The project I am working on):

And I have been working on it for barely a week now ! The benefits for Kivy you ask? Check this

The reason why I chose this is, its look and that it can be used in mobile as well.

you can call the button_click event by passing..

private void SubGraphButton_Click(object sender, RoutedEventArgs args)
{
}

private void ChildNode_Click(object sender, RoutedEventArgs args)
{
   SubGraphButton_Click(sender, args);
}

Also without passing..

private void SubGraphButton_Click(object sender, EventArgs args)
{
}

private void Some_Method() //this method is called
{
   SubGraphButton_Click(new object(), new EventArgs());
}

From APUE, Section 5.14 :

char    good_template[] = "/tmp/dirXXXXXX"; /* right way */
char    *bad_template = "/tmp/dirXXXXXX";   /* wrong way*/

... For the first template, the name is allocated on the stack, because we use an array variable. For the second name, however, we use a pointer. In this case, only the memory for the pointer itself resides on the stack; the compiler arranges for the string to be stored in the read-only segment of the executable. When the mkstemp function tries to modify the string, a segmentation fault occurs.

The quoted text matches @Ciro Santilli 's explanation.

<?php
function current_url()
{
    $url      = "http://" . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
    $validURL = str_replace("&", "&amp", $url);
    return $validURL;
}
//echo "page URL is : ".current_url();

$offer_url = current_url();

?>

Based on the answers by Ben Carp and Wallace Sidhrée:

This is what I use to copy my entire build folder to my wamp public folder.

package.json

{
  "name": "[your project name]",
  "homepage": "http://localhost/[your project name]/",
  "version": "0.0.1",
  [...]
  "scripts": {
    "build": "react-scripts build",
    "postbuild": "@powershell -NoProfile -ExecutionPolicy Unrestricted -Command ./post_build.ps1",
    [...]
  },
}

post_build.ps1

Copy-Item "./build/*" -Destination "C:/wamp64/www/[your project name]" -Recurse -force

The homepage line is only needed if you are deploying to a subfolder on your server (See This answer from another question).

             }
        })(jQuery);

        $(document).ready(function(){

          var url = document.URL, idx = url.indexOf("#") ;
          var hash = idx != -1 ? url.substring(idx+1) : "";

          $(window).load(function(){
             // Remove the # from the hash, as different browsers may or may not include it
             var anchor_to_scroll_to = location.hash.replace('#','');
             if ( anchor_to_scroll_to != '' ) {
                 anchor_to_scroll_to = '#' + anchor_to_scroll_to ;
                 $(anchor_to_scroll_to).goTo();
             }
            });
        });
    /* STOP --- scroll till anchror */

This problem can be easily solved by installing the following Individual components:

You should use Joda Time library because Java Util Date returns wrong values sometimes.

Joda vs Java Util Date

For example days between yesterday (dd-mm-yyyy, 12-07-2016) and first day of year in 1957 (dd-mm-yyyy, 01-01-1957):

public class Main {

public static void main(String[] args) {
    SimpleDateFormat format = new SimpleDateFormat("dd-MM-yyyy");

    Date date = null;
    try {
        date = format.parse("12-07-2016");
    } catch (ParseException e) {
        e.printStackTrace();
    }

    //Try with Joda - prints 21742
    System.out.println("This is correct: " + getDaysBetweenDatesWithJodaFromYear1957(date));
    //Try with Java util - prints 21741
    System.out.println("This is not correct: " + getDaysBetweenDatesWithJavaUtilFromYear1957(date));    
}


private static int getDaysBetweenDatesWithJodaFromYear1957(Date date) {
    DateTime jodaDateTime = new DateTime(date);
    DateTimeFormatter formatter = DateTimeFormat.forPattern("dd-MM-yyyy");
    DateTime y1957 = formatter.parseDateTime("01-01-1957");

    return Days.daysBetween(y1957 , jodaDateTime).getDays();
}

private static long getDaysBetweenDatesWithJavaUtilFromYear1957(Date date) {
    SimpleDateFormat format = new SimpleDateFormat("dd-MM-yyyy");

    Date y1957 = null;
    try {
        y1957 = format.parse("01-01-1957");
    } catch (ParseException e) {
        e.printStackTrace();
    }

    return TimeUnit.DAYS.convert(date.getTime() - y1957.getTime(), TimeUnit.MILLISECONDS);
}

So I really advice you to use Joda Time library.

/** length should be less than 4 (for int) **/
public long byteToInt(byte[] bytes, int length) {
        int val = 0;
        if(length>4) throw new RuntimeException("Too big to fit in int");
        for (int i = 0; i < length; i++) {
            val=val<<8;
            val=val|(bytes[i] & 0xFF);
        }
        return val;
    }

In my case, I added:

Content-Type: application/x-www-form-urlencoded

solved my problem completely.

This error might occur when you return an object instead of a string in your __unicode__ method. For example:

class Author(models.Model):
    . . . 
    name = models.CharField(...)


class Book(models.Model):
    . . .
    author = models.ForeignKey(Author, ...)
    . . .
    def __unicode__(self):
        return self.author  # <<<<<<<< this causes problems

To avoid this error you can cast the author instance to unicode:

class Book(models.Model):
    . . . 
    def __unicode__(self):
        return unicode(self.author)  # <<<<<<<< this is OK

You can use delegate_to to run commands on your Ansible host (admin host), from where you are running your Ansible play. For example:

Delete a file if it already exists on Ansible host:

 - name: Remove file if already exists
   file:
    path: /tmp/logfile.log
    state: absent
    mode: "u+rw,g-wx,o-rwx"
   delegate_to: 127.0.0.1

Create a new file on Ansible host :

 - name: Create log file
   file:
    path: /tmp/logfile.log
    state: touch
    mode: "u+rw,g-wx,o-rwx"
   delegate_to: 127.0.0.1

How about

# pattern is by finding a set of numbers in the start and capturing them
as.numeric(gsub("([0-9]+).*$", "\\1", years))

or

# pattern is to just remove _years_old
as.numeric(gsub(" years old", "", years))

or

# split by space, get the element in first index
as.numeric(sapply(strsplit(years, " "), "[[", 1))

To convert any object or object list into JSON, we have to use the function JsonConvert.SerializeObject.

The below code demonstrates the use of JSON in an ASP.NET environment:

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using Newtonsoft.Json;
using System.Collections.Generic;

namespace JSONFromCS
{
    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e1)
        {
            List<Employee> eList = new List<Employee>();
            Employee e = new Employee();
            e.Name = "Minal";
            e.Age = 24;

            eList.Add(e);

            e = new Employee();
            e.Name = "Santosh";
            e.Age = 24;

            eList.Add(e);

            string ans = JsonConvert.SerializeObject(eList, Formatting.Indented);

            string script = "var employeeList = {\"Employee\": " + ans+"};";
            script += "for(i = 0;i<employeeList.Employee.length;i++)";
            script += "{";
            script += "alert ('Name : ='+employeeList.Employee[i].Name+' 
            Age : = '+employeeList.Employee[i].Age);";
            script += "}";

            ClientScriptManager cs = Page.ClientScript;
            cs.RegisterStartupScript(Page.GetType(), "JSON", script, true);
        }
    }
    public class Employee
    {
        public string Name;
        public int Age;
    }
}  

After running this program, you will get two alerts

In the above example, we have created a list of Employee object and passed it to function "JsonConvert.SerializeObject". This function (JSON library) will convert the object list into JSON format. The actual format of JSON can be viewed in the below code snippet:

{ "Maths" : [ {"Name"     : "Minal",        // First element
                             "Marks"     : 84,
                             "age"       : 23 },
                             {
                             "Name"      : "Santosh",    // Second element
                             "Marks"     : 91,
                             "age"       : 24 }
                           ],                       
              "Science" :  [ 
                             {
                             "Name"      : "Sahoo",     // First Element
                             "Marks"     : 74,
                             "age"       : 27 }, 
                             {                           
                             "Name"      : "Santosh",    // Second Element
                             "Marks"     : 78,
                             "age"       : 41 }
                           ] 
            } 

Syntax:

• {} - acts as 'containers'

• [] - holds arrays

• : - Names and values are separated by a colon

• , - Array elements are separated by commas

This code is meant for intermediate programmers, who want to use C# 2.0 to create JSON and use in ASPX pages.

You can create JSON from JavaScript end, but what would you do to convert the list of object into equivalent JSON string from C#. That's why I have written this article.

In C# 3.5, there is an inbuilt class used to create JSON named JavaScriptSerializer.

The following code demonstrates how to use that class to convert into JSON in C#3.5.

JavaScriptSerializer serializer = new JavaScriptSerializer()
return serializer.Serialize(YOURLIST);   

So, try to create a List of arrays with Questions and then serialize this list into JSON

You can do this very easy, look my Supervisor recipe:

    dest: "/etc/supervisor/conf.d/{{ item.job }}.conf"
    owner: root
    group: root
    force: yes
    mode: 0644
  with_items:
    - { job: bender, arguments: "-m 64", instances: 3 }
    - { job: mailer, arguments: "-m 1024", instances: 2 }
  notify: Ensure Supervisor is restarted

job.conf.j2:

It uses c#, and unityscript(javascript), which is supported by the source code in c++, and c++ plugin support(source code, and plugins require pro).

The unity3d script reference is really easy to understand/use if needed, probably the easiest out of engines like cryengine, udk, etc.

Hope this helps.

I think you can use thread like demon-thread for reading your input and your output reader will already be in while loop in main thread so you can read and write at same time.You can modify your program like this:

Thread T=new Thread(new Runnable() {

    @Override
    public void run() {
        while(true)
        {
            String input = scan.nextLine();
            input += "\n";
            try {
                writer.write(input);
                writer.flush();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

        }

    }
} );
T.start();

and you can reader will be same as above i.e.

while ((line = reader.readLine ()) != null) {
    System.out.println ("Stdout: " + line);
}

make your writer as final otherwise it wont be able to accessible by inner class.

You can create a temp table variable and insert the data into it, then insert the data into your actual table by selecting it from the temp table.

 declare @TableVar table 
 (
    firstCol varchar(50) NOT NULL,
    secondCol varchar(50) NOT NULL
 )

BULK INSERT @TableVar FROM 'PathToCSVFile' WITH (FIELDTERMINATOR = ',', ROWTERMINATOR = '\n')
GO

INSERT INTO dbo.ExistingTable
(
    firstCol,
    secondCol
)
SELECT firstCol,
       secondCol
FROM @TableVar

GO

I like smas's answer that uses replaceAll with a regular expression. If you are going to be doing the same replacement many times, it makes sense to pre-compile the regular expression once:

import java.util.regex.Pattern;

public class Test { 

    private static final Pattern fooPattern = Pattern.compile("(?i)foo");

    private static removeFoo(s){
        if (s != null) s = fooPattern.matcher(s).replaceAll("");
        return s;
    }

    public static void main(String[] args) {
        System.out.println(removeFoo("FOOBar"));
    }
}

Go to Project | Properties and then Assembly Information and then Assembly Version and put an * in the last or the second-to-last box (you can't auto-increment the Major or Minor components).

Simply override the min-height set in .navbar like so:

.navbar{
  min-height:20px; //* or whatever height you require
}

Altering an elements height to something smaller than the min-height won't make a difference...

AssertionError is an Unchecked Exception which rises explicitly by programmer or by API Developer to indicate that assert statement fails.

assert(x>10);

Output:

AssertionError

If x is not greater than 10 then you will get runtime exception saying AssertionError.

As others have said, Stopwatch is a good class to use here. You can wrap it in a helpful method:

public static TimeSpan Time(Action action)
{
    Stopwatch stopwatch = Stopwatch.StartNew();
    action();
    stopwatch.Stop();
    return stopwatch.Elapsed;
}

(Note the use of Stopwatch.StartNew(). I prefer this to creating a Stopwatch and then calling Start() in terms of simplicity.) Obviously this incurs the hit of invoking a delegate, but in the vast majority of cases that won't be relevant. You'd then write:

TimeSpan time = StopwatchUtil.Time(() =>
{
    // Do some work
});

You could even make an ITimer interface for this, with implementations of StopwatchTimer, CpuTimer etc where available.

If you want to open another application and it is not installed you can send it to the Google App Store to download

1. First create the openOtherApp method for example

   public static boolean openOtherApp(Context context, String packageName) {
       PackageManager manager = context.getPackageManager();
        try {
           Intent intent = manager.getLaunchIntentForPackage(packageName);
           if (intent == null) {
               //the app is not installed
               try {
                   intent = new Intent(Intent.ACTION_VIEW);
                   intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                   intent.setData(Uri.parse("market://details?id=" + packageName));
                   context.startActivity(intent);
               } catch (ActivityNotFoundException e) {
                   //throw new ActivityNotFoundException();
                   return false;
               }
   
            }
            intent.addCategory(Intent.CATEGORY_LAUNCHER);
            context.startActivity(intent);
            return true;
       } catch (ActivityNotFoundException e) {
           return false;
       }
   
   }

openOtherApp(getApplicationContext(), "com.packageappname");

Not a direct answer but it could help.

I run most of my dockerized services tied to own static ips using the next approach:

1. I create ip aliases for all services on docker host
2. Then I run each service redirecting ports from this ip into container so each service have own static ip which could be used by external users and other containers.

Sample:

docker run --name dns --restart=always -d -p 172.16.177.20:53:53/udp dns
docker run --name registry --restart=always -d -p 172.16.177.12:80:5000 registry
docker run --name cache --restart=always -d -p 172.16.177.13:80:3142 -v /data/cache:/var/cache/apt-cacher-ng cache
docker run --name mirror --restart=always -d -p 172.16.177.19:80:80 -v /data/mirror:/usr/share/nginx/html:ro mirror
...

Using seeds.rb file or FactoryBot is great, but these are respectively great for fixed data structures and testing.

The seedbank gem might give you more control and modularity to your seeds. It inserts rake tasks and you can also define dependencies between your seeds. Your rake task list will have these additions (e.g.):

rake db:seed                    # Load the seed data from db/seeds.rb, db/seeds/*.seeds.rb and db/seeds/ENVIRONMENT/*.seeds.rb. ENVIRONMENT is the current environment in Rails.env.
rake db:seed:bar                # Load the seed data from db/seeds/bar.seeds.rb
rake db:seed:common             # Load the seed data from db/seeds.rb and db/seeds/*.seeds.rb.
rake db:seed:development        # Load the seed data from db/seeds.rb, db/seeds/*.seeds.rb and db/seeds/development/*.seeds.rb.
rake db:seed:development:users  # Load the seed data from db/seeds/development/users.seeds.rb
rake db:seed:foo                # Load the seed data from db/seeds/foo.seeds.rb
rake db:seed:original           # Load the seed data from db/seeds.rb

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

I have been working with our DBA to copy an audit table with 240M rows to another database.

Using a simple select/insert created a huge tempdb file.

Using a the Import/Export wizard worked but copied 8M rows in 10min

Creating a custom SSIS package and adjusting settings copied 30M rows in 10Min

The SSIS package turned out to be the fastest and most efficent for our purposes

set -x is fine, but if you do something like:

set -x;
command;
set +x;

it would result in printing

+ command
+ set +x;

You can use a subshell to prevent that such as:

(set -x; command)

which would just print the command.

Try using xpath. You can use it to parse elements out of an xml tree.

The title attribute works on most HTML tags and is widely supported by modern browsers.

A lot of the answers above (and on duplicates of this question) rely on installed.packages which is bad form. From the documentation:

This can be slow when thousands of packages are installed, so do not use this to find out if a named package is installed (use system.file or find.package) nor to find out if a package is usable (call require and check the return value) nor to find details of a small number of packages (use packageDescription). It needs to read several files per installed package, which will be slow on Windows and on some network-mounted file systems.

So, a better approach is to attempt to load the package using require and and install if loading fails (require will return FALSE if it isn't found). I prefer this implementation:

using<-function(...) {
    libs<-unlist(list(...))
    req<-unlist(lapply(libs,require,character.only=TRUE))
    need<-libs[req==FALSE]
    if(length(need)>0){ 
        install.packages(need)
        lapply(need,require,character.only=TRUE)
    }
}

which can be used like this:

using("RCurl","ggplot2","jsonlite","magrittr")

This way it loads all the packages, then goes back and installs all the missing packages (which if you want, is a handy place to insert a prompt to ask if the user wants to install packages). Instead of calling install.packages separately for each package it passes the whole vector of uninstalled packages just once.

Here's the same function but with a windows dialog that asks if the user wants to install the missing packages

using<-function(...) {
    libs<-unlist(list(...))
    req<-unlist(lapply(libs,require,character.only=TRUE))
    need<-libs[req==FALSE]
    n<-length(need)
    if(n>0){
        libsmsg<-if(n>2) paste(paste(need[1:(n-1)],collapse=", "),",",sep="") else need[1]
        print(libsmsg)
        if(n>1){
            libsmsg<-paste(libsmsg," and ", need[n],sep="")
        }
        libsmsg<-paste("The following packages could not be found: ",libsmsg,"\n\r\n\rInstall missing packages?",collapse="")
        if(winDialog(type = c("yesno"), libsmsg)=="YES"){       
            install.packages(need)
            lapply(need,require,character.only=TRUE)
        }
    }
}

The following solution works well when you want to move the text closer to the bullet and even if you have multiple lines of text.

margin-right allows you to move the text closer to the bullet

text-indent ensures that multiple lines of text still line up correctly

li:before {_x000D_
  content: "";_x000D_
  margin-right: -5px; /* Adjust this to move text closer to the bullet */_x000D_
}_x000D_
_x000D_
li {_x000D_
  text-indent: 5px; /* Aligns second line of text */_x000D_
}

<ul>_x000D_
  <li> Item 1 ... </li>_x000D_
  <li> Item 2 ... this item has tons and tons of text that causes a second line! Notice how even the second line is lined up with the first!</li>_x000D_
  <li> Item 3 ... </li>_x000D_
</ul>

A very direct way is to just use read.table on your character vector:

> read.table(text = text, sep = ".", colClasses = "character")
   V1 V2  V3  V4
1   F US CLE V13
2   F US CA6 U13
3   F US CA6 U13
4   F US CA6 U13
5   F US CA6 U13
6   F US CA6 U13
7   F US CA6 U13
8   F US CA6 U13
9   F US  DL U13
10  F US  DL U13
11  F US  DL U13
12  F US  DL Z13
13  F US  DL Z13

colClasses needs to be specified, otherwise F gets converted to FALSE (which is something I need to fix in "splitstackshape", otherwise I would have recommended that :) )

Update (> a year later)...

Alternatively, you can use my cSplit function, like this:

cSplit(as.data.table(text), "text", ".")
#     text_1 text_2 text_3 text_4
#  1:      F     US    CLE    V13
#  2:      F     US    CA6    U13
#  3:      F     US    CA6    U13
#  4:      F     US    CA6    U13
#  5:      F     US    CA6    U13
#  6:      F     US    CA6    U13
#  7:      F     US    CA6    U13
#  8:      F     US    CA6    U13
#  9:      F     US     DL    U13
# 10:      F     US     DL    U13
# 11:      F     US     DL    U13
# 12:      F     US     DL    Z13
# 13:      F     US     DL    Z13

Or, separate from "tidyr", like this:

library(dplyr)
library(tidyr)

as.data.frame(text) %>% separate(text, into = paste("V", 1:4, sep = "_"))
#    V_1 V_2 V_3 V_4
# 1    F  US CLE V13
# 2    F  US CA6 U13
# 3    F  US CA6 U13
# 4    F  US CA6 U13
# 5    F  US CA6 U13
# 6    F  US CA6 U13
# 7    F  US CA6 U13
# 8    F  US CA6 U13
# 9    F  US  DL U13
# 10   F  US  DL U13
# 11   F  US  DL U13
# 12   F  US  DL Z13
# 13   F  US  DL Z13

try this:

SELECT ReportId, Email = 
    STUFF((SELECT ', ' + Email
           FROM your_table b

          FOR XML PATH('')), 1, 2, '')

SQL fiddle demo

import java.io.BufferedReader;
import java.io.InputStreamReader;

public class Main {

    public static void main(String[] args) throws Exception {
        ProcessBuilder pb = new ProcessBuilder("script.bat");
        pb.redirectErrorStream(true);
        Process p = pb.start();
        BufferedReader logReader = new BufferedReader(new InputStreamReader(p.getInputStream()));
        String logLine = null;
        while ( (logLine = logReader.readLine()) != null) {
           System.out.println("Script output: " + logLine);
        }
    }
}

By using this line: pb.redirectErrorStream(true); we can combine InputStream and ErrorStream

TL;DR: This is the equivalent to find -type f to go over all files in all folders below and including the current one:

for currentpath, folders, files in os.walk('.'):
    for file in files:
        print(os.path.join(currentpath, file))

As already mentioned in other answers, os.walk() is the answer, but it could be explained better. It's quite simple! Let's walk through this tree:

docs/
+-- doc1.odt
pics/
todo.txt

With this code:

for currentpath, folders, files in os.walk('.'):
    print(currentpath)

The currentpath is the current folder it is looking at. This will output:

.
./docs
./pics

So it loops three times, because there are three folders: the current one, docs, and pics. In every loop, it fills the variables folders and files with all folders and files. Let's show them:

for currentpath, folders, files in os.walk('.'):
    print(currentpath, folders, files)

This shows us:

# currentpath  folders           files
.              ['pics', 'docs']  ['todo.txt']
./pics         []                []
./docs         []                ['doc1.odt']

So in the first line, we see that we are in folder ., that it contains two folders namely pics and docs, and that there is one file, namely todo.txt. You don't have to do anything to recurse into those folders, because as you see, it recurses automatically and just gives you the files in any subfolders. And any subfolders of that (though we don't have those in the example).

If you just want to loop through all files, the equivalent of find -type f, you can do this:

for currentpath, folders, files in os.walk('.'):
    for file in files:
        print(os.path.join(currentpath, file))

This outputs:

./todo.txt
./docs/doc1.odt

    }

}

You could additionally save it to file based on your needs or parse it using XML or HTML libraries.

The next approach work to me with Visual Studio 2013 Update 4 1- From Solution Explorer right click on References then select add references 2- Assemblies > Framework > System.Data.OracleClient > OK and after that you free to add using System.Data.OracleClient in your application and deal with database like you do with Sql Server database except changing the prefix from Sql to Oracle as in SqlCommand become OracleCommand for example to link to Oracle XE

OracleConnection oraConnection = new OracleConnection(@"Data Source=XE; User ID=system; Password=*myPass*");
public void Open()
{
if (oraConnection.State != ConnectionState.Open)
{
oraConnection.Open();
}
}
public void Close()
{
if (oraConnection.State == ConnectionState.Open)
{
oraConnection.Close();
}}

and to execute some command like INSERT, UPDATE, or DELETE using stored procedure we can use the following method

public void ExecuteCMD(string storedProcedure, OracleParameter[] param)
{
OracleCommand oraCmd = new OracleCommand();
oraCmd,CommandType = CommandType.StoredProcedure;
oraCmd.CommandText = storedProcedure;
oraCmd.Connection = oraConnection;

if(param!=null)
{
oraCmd.Parameters.AddRange(param);
}
try
{
oraCmd.ExecuteNoneQuery();
}
catch (Exception)
{
MessageBox.Show("Sorry We've got Unknown Error","Connection Error",MessageBoxButtons.OK,MessageBoxIcon.Error);
}
}

The simple solution that worked for me as below, wrap the table with a div and change the line-height, this line-height is taken as a ratio.

<div class="col-md-6" style="line-height: 0.5">_x000D_
                                <table class="table table-striped" >_x000D_
                                    <thead>_x000D_
                                    <tr>_x000D_
                                        <th>Parameter</th>_x000D_
                                        <th>Recorded Value</th>_x000D_
                                        <th>Individual Score</th>_x000D_
                                    </tr>_x000D_
                                    </thead>_x000D_
                                    <tbody>_x000D_
                                    <tr>_x000D_
                                        <td>Respiratory Rate</td>_x000D_
                                        <td>Doe</td>_x000D_
                                        <td>[email protected]</td>_x000D_
                                    </tr>_x000D_
                                    <tr>_x000D_
                                        <td>Respiratory Effort</td>_x000D_
                                        <td>Moe</td>_x000D_

                                    </tr>_x000D_
                                    <tr>_x000D_
                                        <td>Oxygon Saturation</td>_x000D_

                                        <td>[email protected]</td>_x000D_
                                    </tr>_x000D_
                                    </tbody>_x000D_
                                </table>_x000D_
                            </div>

Try changing the value as it fits for you.

According to Collections Framework Overview you have two balanced tree implementations:

• TreeSet

On Android 6 with ADB version 1.0.32, you have to put / behind the folder you want to copy. E.g adb pull "/sdcard/".

Install jupyter. Open terminal. Go to folder where you file is (in terminal ie.cd path/to/folder). Run jupyter notebook. And voila: you have something like this:

Notice that to open a notebook in the folder, you can either click on it in the browser or go to address:

http://localhost:8888/notebooks/name_of_your_file.ipynb

I've found a very nice and concise solution, especially useful when you cannot modify enum classes as it was in my case. Then you should provide a custom ObjectMapper with a certain feature enabled. Those features are available since Jackson 1.6.

public class CustomObjectMapper extends ObjectMapper {
    @PostConstruct
    public void customConfiguration() {
        // Uses Enum.toString() for serialization of an Enum
        this.enable(WRITE_ENUMS_USING_TO_STRING);
        // Uses Enum.toString() for deserialization of an Enum
        this.enable(READ_ENUMS_USING_TO_STRING);
    }
}

There are more enum-related features available, see here:

https://github.com/FasterXML/jackson-databind/wiki/Serialization-features https://github.com/FasterXML/jackson-databind/wiki/Deserialization-Features

Make outer <div> to position: relative and inner <div> to position: absolute. It should work for you.

Are you using php 5.4 on your local? the render line is using the new way of initializing arrays. Try replacing ["title" => "Welcome "] with array("title" => "Welcome ")

As the html5 way (my previous answer) is not available in all browsers, heres another slightly hack way.

This solution requires you are serving the intended file from same domain, OR has CORS permission.

1. First download the content of the file via XMLHttpRequest(Ajax).
2. Then make a data URI by base64 encoding the content of the file and set media-type to application/octet-stream. Result should look like

data:application/octet-stream;base64,SGVsbG8sIFdvcmxkIQ%3D%3D

Now set location.href = data. This will cause the browser to download the file. Unfortunately you can't set file name or extension this way. Fiddling with the media-type could yield something.

See details: https://developer.mozilla.org/en-US/docs/Web/HTTP/data_URIs

You can use sys.master_files.

Contains a row per file of a database as stored in the master database. This is a single, system-wide view.

The biggest use of partial classes is to make life easier for code generators / designers. Partial classes allow the generator to simply emit the code they need to emit and they do not have to deal with user edits to the file. Users are likewise free to annotate the class with new members by having a second partial class. This provides a very clean framework for separation of concerns.

A better way to look at it is to see how designers functioned before partial classes. The WinForms designer would spit out all of the code inside of a region with strongly worded comments about not modifying the code. It had to insert all sorts of heuristics to find the generated code for later processing. Now it can simply open the designer.cs file and have a high degree of confidence that it contains only code relevant to the designer.

You need

.abc,.ab {
    display: none;
}

#f:hover ~ .ab {
    display: block;
}

#s:hover ~ .abc {
    display: block;
}

#s:hover ~ .a,
#f:hover ~ .a{
    display: none;
}

Updated demo at http://jsfiddle.net/gaby/n5fzB/2/

The problem in your original CSS was that the , in css selectors starts a completely new selector. it is not combined.. so #f:hover ~ .abc,.a means #f:hover ~ .abc and .a. You set that to display:none so it was always set to be hidden for all .a elements.

head:

Name

head - output the first part of files

Synopsis

head [OPTION]... [FILE]...

Description

Print the first 10 lines of each FILE to standard output. With more than one FILE, precede each with a header giving the file name. With no FILE, or when FILE is -, read standard input.

Mandatory arguments to long options are mandatory for short options too.
-c, --bytes=[-]N print the first N bytes of each file; with the leading '-', print all but the last N bytes of each file

string replace() function perfectly solves this problem:

string.replace(s, old, new[, maxreplace])

Return a copy of string s with all occurrences of substring old replaced by new. If the optional argument maxreplace is given, the first maxreplace occurrences are replaced.

>>> u'longlongTESTstringTEST'.replace('TEST', '?', 1)
u'longlong?stringTEST'

            finalJsonArray.put(jsonObject);
            String username2 = jsonObject.getString("userName");
            if (username2.equals(username)) {
                has = true;
            }
            System.out.println("user name  are :" + username2);
            JSONObject jsonObject2 = jsonObject.getJSONObject("languages");
            String eng = jsonObject2.getString("Eng");

            String ger = jsonObject2.getString("Ger");
            jsonObject2.put("Eng", "ChangeEnglishValueCheckForLongValue");
            System.out.println(" Eng : " + eng + "  Fin " + fin + "  ger : " + ger);
        }
        System.out.println("Final JSON Array \n" + json);
        jsonArray.put(setNewUserPreference());
        return json;
    }

Put ALTER COLUMN statement inside a bracket, it should work.

ALTER TABLE tblcommodityOHLC alter ( column  
CC_CommodityContractID NUMERIC(18,0), 
CM_CommodityID NUMERIC(18,0) )

When you writing scripts performance does not matter (in most cases).
If you care about performance 'Python vs Bash' is a false question.

Python:
+ easier to write
+ easier to maintain
+ easier code reuse (try to find universal error-proof way to include files with common code in sh, I dare you)
+ you can do OOP with it too!
+ easier arguments parsing. well, not easier, exactly. it still will be too wordy to my taste, but python have argparse facility built in.
- ugly ugly 'subprocess'. try to chain commands and not to cry a river how ugly your code will become. especially if you care about exit codes.

Bash:
+ ubiquity, as was said earlier, indeed.
+ simple commands chaining. that's how you glue together different commands in a simple way. Also Bash (not sh) have some improvements, like pipefail, so chaining is really short and expressive.
+ do not require 3rd-party programs to be installed. can be executed right away.
- god, it's full of gotchas. IFS, CDPATH.. thousands of them.

If one writing a script bigger than 100 LOC: choose Python
If one need path manipulation in script: choose Python(3)
If one need somewhat like alias but slightly complicated: choose Bash/sh

Anyway, one should try both sides to get the idea what are they capable of.

Maybe answer can be extended with packaging and IDE support points, but I'm not familiar with this sides.

As always you have to choose from turd sandwich and giant douche. And remember, just a few years ago Perl was new hope. Where it is now.

Follow up answer to help anyone doing this with the VS docker integration. I needed to change to port 8080 to run using the "flexible" environment in google appengine.

You'll need the following in your Dockerfile:

ENV ASPNETCORE_URLS=http://+:8080
EXPOSE 8080

and you'll need to modify the port in docker-compose.yml as well:

    ports:
      - "8080"

You can just substract two date objects.

var d1 = new Date(); //"now"
var d2 = new Date("2011/02/01")  // some date
var diff = Math.abs(d1-d2);  // difference in milliseconds

You can either do

SELECT name
FROM table2
WHERE name NOT IN
    (SELECT name 
     FROM table1)

or

SELECT name 
FROM table2 
WHERE NOT EXISTS 
    (SELECT * 
     FROM table1 
     WHERE table1.name = table2.name)

Just adding an example that worked fine for me:

$sqldb = [string]($sqldir) + '\bin\MySQLInstanceConfig.exe'
$myarg = '-i ConnectionUsage=DSS Port=3311 ServiceName=MySQL RootPassword= ' + $rootpw
Start-Process $sqldb -ArgumentList $myarg

Programmatically, with spring boot 2.1.5:

import org.springframework.boot.web.server.WebServerFactoryCustomizer;
import org.springframework.boot.web.servlet.server.ConfigurableServletWebServerFactory;
import org.springframework.stereotype.Component;

@Component
public class CustomizationBean implements WebServerFactoryCustomizer<ConfigurableServletWebServerFactory> {

    @Override
    public void customize(ConfigurableServletWebServerFactory server) {
        server.setPort(9000);
    }

}

You are setting the ScaleType to ScaleType.FIT_XY. According to the javadocs, this will stretch the image to fit the whole area, changing the aspect ratio if necessary. That would explain the behavior you are seeing.

To get the behavior you want... FIT_CENTER, FIT_START, or FIT_END are close, but if the image is narrower than it is tall, it will not start to fill the width. You could look at how those are implemented though, and you should probably be able to figure out how to adjust it for your purpose.

    idx = np.arange( 0, 18, 1 )

I prefer to use WebClient, it seems to handle SSL transparently:

I had a similar problem. It turned out, I was including an old header file of the same name from an old folder. I deleted the old file changed the #include directive to point to my new file and all was good.

Add another varChar(255) column (with default as empty string not null) to hold the overflow when 255 chars are not enough, and change this PK to use both columns. This does not sound like a well designed database schema however, and I would recommend getting a data modeler to look at what you have with a view towards refactoring it for more Normalization.

To stop executing java code just use this command:

    System.exit(1);

After this command java stops immediately!

for example:

    int i = 5;
    if (i == 5) {
       System.out.println("All is fine...java programm executes without problem");
    } else {
       System.out.println("ERROR occured :::: java programm has stopped!!!");
       System.exit(1);
    }

As mentioned in other answers, all of the following will work for the standard string-based syntax.

WAITFOR DELAY '02:00' --Two hours
WAITFOR DELAY '00:02' --Two minutes
WAITFOR DELAY '00:00:02' --Two seconds
WAITFOR DELAY '00:00:00.200' --Two tenths of a seconds

There is also an alternative method of passing it a DATETIME value. You might think I'm confusing this with WAITFOR TIME, but it also works for WAITFOR DELAY.

Considerations for passing DATETIME:

• It must be passed as a variable, so it isn't a nice one-liner anymore.
• The delay is measured as the time since the Epoch ('1900-01-01').
• For situations that require a variable amount of delay, it is much easier to manipulate a DATETIME than to properly format a VARCHAR.

How to wait for 2 seconds:

--Example 1
DECLARE @Delay1 DATETIME
SELECT @Delay1 = '1900-01-01 00:00:02.000'
WAITFOR DELAY @Delay1

--Example 2
DECLARE @Delay2 DATETIME
SELECT @Delay2 = dateadd(SECOND, 2, convert(DATETIME, 0))
WAITFOR DELAY @Delay2

A note on waiting for TIME vs DELAY:

Have you ever noticed that if you accidentally pass WAITFOR TIME a date that already passed, even by just a second, it will never return? Check it out:

--Example 3
DECLARE @Time1 DATETIME
SELECT @Time1 = getdate()
WAITFOR DELAY '00:00:01'
WAITFOR TIME @Time1 --WILL HANG FOREVER

Unfortunately, WAITFOR DELAY will do the same thing if you pass it a negative DATETIME value (yes, that's a thing).

--Example 4
DECLARE @Delay3 DATETIME
SELECT @Delay3 = dateadd(SECOND, -1, convert(DATETIME, 0))
WAITFOR DELAY @Delay3 --WILL HANG FOREVER

However, I would still recommend using WAITFOR DELAY over a static time because you can always confirm your delay is positive and it will stay that way for however long it takes your code to reach the WAITFOR statement.

You don't need --header "Content-Length: $LENGTH".

curl --request POST --data-binary "@template_entry.xml" $URL

Note that GET request does not support content body widely.

Also remember that POST request have 2 different coding schema. This is first form:

  $ nc -l -p 6666 &
  $ curl  --request POST --data-binary "@README" http://localhost:6666

POST / HTTP/1.1
User-Agent: curl/7.21.0 (x86_64-pc-linux-gnu) libcurl/7.21.0 OpenSSL/0.9.8o zlib/1.2.3.4 libidn/1.15 libssh2/1.2.6

.. contents::

You probably request this:

-F/--form name=content
           (HTTP) This lets curl emulate a filled-in form in
              which a user has pressed the submit button. This
              causes curl to POST data using the Content- Type
              multipart/form-data according to RFC2388. This
              enables uploading of binary files etc. To force the
              'content' part to be a file, prefix the file name
              with an @ sign. To just get the content part from a
              file, prefix the file name with the symbol <. The
              difference between @ and < is then that @ makes a
              file get attached in the post as a file upload,
              while the < makes a text field and just get the
              contents for that text field from a file.

Try this

$('body').on('change', '#multiid', function() {
    // your stuff
})

please check .on() selector

C is a very low-level language, so it permits you to create almost any legal object (.o) file that you can conceive of. You should think of C as basically dressed-up assembly language.

In particular, C does not require functions to be declared before they are used. If you call a function without declaring it, the use of the function becomes it's (implicit) declaration. In a simple test I just ran, this is only a warning in the case of built-in library functions like printf (at least in GCC), but for random functions, it will compile just fine.

Of course, when you try to link, and it can't find foo, then you will get an error.

In the case of library functions like printf, some compilers contain built-in declarations for them so they can do some basic type checking, so when the implicit declaration (from the use) doesn't match the built-in declaration, you'll get a warning.

If you're using jQueryUI - there is an onDrag event. If you're not, then attach your listener to mouseup(), not click().

Use jQuery....I know you say you're trying to teach someone javascript, but teach him a cleaner technique... for instance, I could:

<select id="navigation">
    <option value="unit_01.htm">Unit 1</option>
    <option value="#5.2">Bookmark 2</option>
</select>

And with a little jQuery, you could do:

$("#navigation").change(function()
{
    document.location.href = $(this).val();
});

Unobtrusive, and with clean separation of logic and UI.

The modulo operator % in C and C++ is defined for two integers, however, there is an fmod() function available for usage with doubles.

There's a set_ticks() function for axis objects.

you can create addHeaderView and use

adapter.addHeaderView(View).

This code build the addHeaderView for more then one header. the headers should have:

android:layout_height="wrap_content"

public class MyAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
    private static final int TYPE_ITEM = -1;
    public class MyViewSHolder extends RecyclerView.ViewHolder {
        public MyViewSHolder (View view) {
            super(view);
        }
        // put you code. for example:
        View mView;
        ...
    }

    public class ViewHeader extends RecyclerView.ViewHolder {
        public ViewHeader(View view) {
            super(view);
        }
    }

    private List<View> mHeaderViews = new ArrayList<>();
    public void addHeaderView(View headerView) {
        mHeaderViews.add(headerView);
    }

    @Override
    public int getItemCount() {
       return ... + mHeaderViews.size();
    }

    @Override
    public int getItemViewType(int position) {
        if (mHeaderViews.size() > position) {
            return position;
        }

        return TYPE_ITEM;
    }
    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        if (viewType != TYPE_ITEM) {
            //inflate your layout and pass it to view holder
            return new ViewHeader(mHeaderViews.get(viewType));
        }
        ...
    }
    @Override
    public void onBindViewHolder(RecyclerView.ViewHolder holder, int basePosition1) {
        if (holder instanceof ViewHeader) {
            return;
        }
        int basePosition = basePosition1 -  mHeaderViews.size();
        ...
    }
}

Pop off the first and last digits and compare them until you run out. There may be a digit left, or not, but either way, if all the popped off digits match, it is a palindrome.

InvariantCulture

Uses a "standard" set of character orderings (a,b,c, ... etc.). This is in contrast to some specific locales, which may sort characters in different orders ('a-with-acute' may be before or after 'a', depending on the locale, and so on).

Ordinal

On the other hand, looks purely at the values of the raw byte(s) that represent the character.

There's a great sample at http://msdn.microsoft.com/en-us/library/e6883c06.aspx that shows the results of the various StringComparison values. All the way at the end, it shows (excerpted):

StringComparison.InvariantCulture:
LATIN SMALL LETTER I (U+0069) is less than LATIN SMALL LETTER DOTLESS I (U+0131)
LATIN SMALL LETTER I (U+0069) is less than LATIN CAPITAL LETTER I (U+0049)
LATIN SMALL LETTER DOTLESS I (U+0131) is greater than LATIN CAPITAL LETTER I (U+0049)

StringComparison.Ordinal:
LATIN SMALL LETTER I (U+0069) is less than LATIN SMALL LETTER DOTLESS I (U+0131)
LATIN SMALL LETTER I (U+0069) is greater than LATIN CAPITAL LETTER I (U+0049)
LATIN SMALL LETTER DOTLESS I (U+0131) is greater than LATIN CAPITAL LETTER I (U+0049)

You can see that where InvariantCulture yields (U+0069, U+0049, U+00131), Ordinal yields (U+0049, U+0069, U+00131).

For me, I have fixed the problem using android:layout_centerVertical="true" in a parent RelativeLayout:

<RelativeLayout ... >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:layout_centerVertical="true">

</RelativeLayout>

try with screen -d -r or screen -D -RR

This is what worked for me: instead of

<script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs"></script>

try

<script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs/dist/tf.min.js"> </script>

After that change I am not seeing the error anymore.

you can print it as string:

printf("%s\n", foo);

According to the jQuery docs, calling toggle() without parameters will toggle visibility.

$('#play-pause').click(function(){
   $('#video-over').toggle();
});

Using GHC 7.0.3, gcc 4.4.6, Linux 2.6.29 on an x86_64 Core2 Duo (2.5GHz) machine, compiling using ghc -O2 -fllvm -fforce-recomp for Haskell and gcc -O3 -lm for C.

• Your C routine runs in 8.4 seconds (faster than your run probably because of -O3)
• The Haskell solution runs in 36 seconds (due to the -O2 flag)
• Your factorCount' code isn't explicitly typed and defaulting to Integer (thanks to Daniel for correcting my misdiagnosis here!). Giving an explicit type signature (which is standard practice anyway) using Int and the time changes to 11.1 seconds
• in factorCount' you have needlessly called fromIntegral. A fix results in no change though (the compiler is smart, lucky for you).
• You used mod where rem is faster and sufficient. This changes the time to 8.5 seconds.
• factorCount' is constantly applying two extra arguments that never change (number, sqrt). A worker/wrapper transformation gives us:

 $ time ./so
 842161320  

 real    0m7.954s  
 user    0m7.944s  
 sys     0m0.004s  

That's right, 7.95 seconds. Consistently half a second faster than the C solution. Without the -fllvm flag I'm still getting 8.182 seconds, so the NCG backend is doing well in this case too.

Conclusion: Haskell is awesome.

Resulting Code

factorCount number = factorCount' number isquare 1 0 - (fromEnum $ square == fromIntegral isquare)
    where square = sqrt $ fromIntegral number
          isquare = floor square

factorCount' :: Int -> Int -> Int -> Int -> Int
factorCount' number sqrt candidate0 count0 = go candidate0 count0
  where
  go candidate count
    | candidate > sqrt = count
    | number `rem` candidate == 0 = go (candidate + 1) (count + 2)
    | otherwise = go (candidate + 1) count

nextTriangle index triangle
    | factorCount triangle > 1000 = triangle
    | otherwise = nextTriangle (index + 1) (triangle + index + 1)

main = print $ nextTriangle 1 1

EDIT: So now that we've explored that, lets address the questions

Question 1: Do erlang, python and haskell lose speed due to using arbitrary length integers or don't they as long as the values are less than MAXINT?

In Haskell, using Integer is slower than Int but how much slower depends on the computations performed. Luckily (for 64 bit machines) Int is sufficient. For portability sake you should probably rewrite my code to use Int64 or Word64 (C isn't the only language with a long).

Question 2: Why is haskell so slow? Is there a compiler flag that turns off the brakes or is it my implementation? (The latter is quite probable as haskell is a book with seven seals to me.)

Question 3: Can you offer me some hints how to optimize these implementations without changing the way I determine the factors? Optimization in any way: nicer, faster, more "native" to the language.

That was what I answered above. The answer was

• 0) Use optimization via -O2
• 1) Use fast (notably: unbox-able) types when possible
• 2) rem not mod (a frequently forgotten optimization) and
• 3) worker/wrapper transformation (perhaps the most common optimization).

Question 4: Do my functional implementations permit LCO and hence avoid adding unnecessary frames onto the call stack?

Yes, that wasn't the issue. Good work and glad you considered this.

For those wanting to have the more common undo/redo functionality, someone has written undo-tree.el. It provides the look and feel of non-Emacs undo, but provides access to the entire 'tree' of undo history.

I like Emacs' built-in undo system, but find this package to be very intuitive.

Here's the commentary from the file itself:

Emacs has a powerful undo system. Unlike the standard undo/redo system in most software, it allows you to recover any past state of a buffer (whereas the standard undo/redo system can lose past states as soon as you redo). However, this power comes at a price: many people find Emacs' undo system confusing and difficult to use, spawning a number of packages that replace it with the less powerful but more intuitive undo/redo system.

Both the loss of data with standard undo/redo, and the confusion of Emacs' undo, stem from trying to treat undo history as a linear sequence of changes. It's not. The `undo-tree-mode' provided by this package replaces Emacs' undo system with a system that treats undo history as what it is: a branching tree of changes. This simple idea allows the more intuitive behaviour of the standard undo/redo system to be combined with the power of never losing any history. An added side bonus is that undo history can in some cases be stored more efficiently, allowing more changes to accumulate before Emacs starts discarding history.

To be clear there are 4 types of caches you can clear depending upon your case.

php artisan cache:clear

You can run the above statement in your console when you wish to clear the application cache. What it does is that this statement clears all caches inside storage\framework\cache.

php artisan route:cache

This clears your route cache. So if you have added a new route or have changed a route controller or action you can use this one to reload the same.

php artisan config:cache 

This will clear the caching of the env file and reload it

php artisan view:clear 

This will clear the compiled view files of your application.

For Shared Hosting

Most of the shared hosting providers don't provide SSH access to the systems. In such a case you will need to create a route and call the following line as below:

Route::get('/clear-cache', function() {
    Artisan::call('cache:clear');
    return "All cache cleared";
});

Try $("input[type='text']").attr('disabled', true);

I wrote a blog post that explains how to access an unpublished port of a container In different ways depending on the needs:

• by committing a new image and running a new container,
• by using socat to avoid restarting the container.

The post also goes through a brief introduction of both how port mapping works, the difference between exposing and publishing a port, and what is socat.

Here’s the link: https://lmcaraig.com/accessing-an-unpublished-port-of-a-running-docker-container

There is the Math.pow(double a, double b) method. Note that it returns a double, you will have to cast it to an int like (int)Math.pow(double a, double b).

For 1.6.x, it can be done using the git_remote_branch tool:

grb track foo upstream

That will cause Git to make foo track upstream/foo.

One method would be to store the result of an inner merge form both dfs, then we can simply select the rows when one column's values are not in this common:

In [119]:

common = df1.merge(df2,on=['col1','col2'])
print(common)
df1[(~df1.col1.isin(common.col1))&(~df1.col2.isin(common.col2))]
   col1  col2
0     1    10
1     2    11
2     3    12
Out[119]:
   col1  col2
3     4    13
4     5    14

EDIT

Another method as you've found is to use isin which will produce NaN rows which you can drop:

In [138]:

df1[~df1.isin(df2)].dropna()
Out[138]:
   col1  col2
3     4    13
4     5    14

However if df2 does not start rows in the same manner then this won't work:

df2 = pd.DataFrame(data = {'col1' : [2, 3,4], 'col2' : [11, 12,13]})

will produce the entire df:

In [140]:

df1[~df1.isin(df2)].dropna()
Out[140]:
   col1  col2
0     1    10
1     2    11
2     3    12
3     4    13
4     5    14

I used the below connection string on the Advanced tab of MySQL Migration Tool Kit to connect to SQL Server 2008 instance:

jdbc:jtds:sqlserver://"sql_server_ip_address":1433/<db_name>;Instance=<sqlserver_instanceName>;user=sa;password=PASSWORD;namedPipe=true;charset=utf-8;domain= 

Usually the parameter has "systemName\instanceName". But in the above, do not add "systemName\" (use only InstanceName).

To check what the instanceName should be, go to services.msc and check the DisplayName of the MSSQL instance. It shows similar to MSSQL$instanceName.

Hope this help in MSSQL connectivity from mysql migration toolKit.

After searching a lot I find out that it is possible to create a new folder from the web interface, but it would require you to have at least one file within the folder when creating it.

When using the normal way of creating new files through the web interface, you can type in the folder into the file name to create the file within that new directory.

For example, if I would like to create the file filename.md in a series of sub-folders, I can do this (taken from the GitHub blog):

var str = "This-is-a-news-item-";
while (str.contains("-")) {
  str = str.replace("-", ' ');
}
alert(str);

I found that one use of str.replace() would only replace the first hyphen, so I looped thru while the input string still contained any hyphens, and replaced them all.

Instead of ((t[1])/length) * t[1] += string, you should use string += ((t[1])/length) * t[1]. (The other syntax issue - int is not iterable - will be your exercise to figure out.)

Placing your list view in a Flexible widget may also help,

Streams Java 8

Along with forEach method that accepts a lambda expression we have also got stream APIs, in Java 8.

Iterate over entries (Using forEach and Streams):

sample.forEach((k,v) -> System.out.println(k + "=" + v)); 
sample.entrySet().stream().forEachOrdered((entry) -> {
            Object currentKey = entry.getKey();
            Object currentValue = entry.getValue();
            System.out.println(currentKey + "=" + currentValue);
        });
sample.entrySet().parallelStream().forEach((entry) -> {
            Object currentKey = entry.getKey();
            Object currentValue = entry.getValue();
            System.out.println(currentKey + "=" + currentValue);
        });

The advantage with streams is they can be parallelized easily and can be useful when we have multiple CPUs at disposal. We simply need to use parallelStream() in place of stream() above. With parallel streams it makes more sense to use forEach as forEachOrdered would make no difference in performance. If we want to iterate over keys we can use sample.keySet() and for values sample.values().

Why forEachOrdered and not forEach with streams ?

Streams also provide forEach method but the behaviour of forEach is explicitly nondeterministic where as the forEachOrdered performs an action for each element of this stream, in the encounter order of the stream if the stream has a defined encounter order. So forEach does not guarantee that the order would be kept. Also check this for more.

I found deleting the contents of node_modules and performing npm install again worked for me.

A jQuery solution

HTML

<select id="foo">
  <option value="1">1</option>
  <option value="2">2</option>
  <option value="3">3</option>
</select>

Javascript

// remove child "option" element with a "value" attribute equal to "2"
$("#foo > option[value='2']").remove();

// remove all child "option" elements
$("#foo > option").remove();

References:

Attribute Equals Selector [name=value]

Selects elements that have the specified attribute with a value exactly equal to a certain value.

Child Selector (“parent > child”)

Selects all direct child elements specified by "child" of elements specified by "parent"

.remove()

Similar to .empty(), the .remove() method takes elements out of the DOM. We use .remove() when we want to remove the element itself, as well as everything inside it. In addition to the elements themselves, all bound events and jQuery data associated with the elements are removed.

Subclassing UITextField is the way to go. Open a playground and add the following code:

class MyTextField : UITextField {
    var leftTextMargin : CGFloat = 0.0

    override func textRectForBounds(bounds: CGRect) -> CGRect {
        var newBounds = bounds
        newBounds.origin.x += leftTextMargin
        return newBounds
    }

    override func editingRectForBounds(bounds: CGRect) -> CGRect {
        var newBounds = bounds
        newBounds.origin.x += leftTextMargin
        return newBounds
    }
}

let tf = MyTextField(frame: CGRect(x: 0, y: 0, width: 100, height: 44))
tf.text = "HELLO"
tf.leftTextMargin = 25
tf.setNeedsLayout()
tf.layoutIfNeeded()
