Minor variation of phillfri's answer which was already a variation of Geoff's answer: I added the ability to handle completely empty tables that contain no data for the Array Code.

Sub AddDataRow(tableName As String, NewData As Variant)
    Dim sheet As Worksheet
    Dim table As ListObject
    Dim col As Integer
    Dim lastRow As Range

    Set sheet = Range(tableName).Parent
    Set table = sheet.ListObjects.Item(tableName)

    'First check if the last row is empty; if not, add a row
    If table.ListRows.Count > 0 Then
        Set lastRow = table.ListRows(table.ListRows.Count).Range
        If Application.CountBlank(lastRow) < lastRow.Columns.Count Then
            table.ListRows.Add
        End If
    End If

    'Iterate through the last row and populate it with the entries from values()
    If table.ListRows.Count = 0 Then 'If table is totally empty, set lastRow as first entry
        table.ListRows.Add Position:=1
        Set lastRow = table.ListRows(1).Range
    Else
        Set lastRow = table.ListRows(table.ListRows.Count).Range
    End If
    For col = 1 To lastRow.Columns.Count
        If col <= UBound(NewData) + 1 Then lastRow.Cells(1, col) = NewData(col - 1)
    Next col
End Sub

The answer by waqas716 is good. I created a workaround for a specific case demanding less code and maintenance.

I found a specific work around by having a static method fetch a view from the activity I suspect to be in the foreground. You can iterate through all activities and check if you wish or get the activity name from martin's answer

ActivityManager am = (ActivityManager)context.getSystemService(Context.ACTIVITY_SERVICE);
ComponentName cn = am.getRunningTasks(1).get(0).topActivity; 

I then check if the view is not null and get the context via getContext().

View v = SuspectedActivity.get_view();

if(v != null)
{
    // an example for using this context for something not 
    // permissible in global application context. 
    v.getContext().startActivity(new Intent("rubberduck.com.activities.SomeOtherActivity"));
}

First of all, from __future__ import print_function needs to be the first line of code in your script (aside from some exceptions mentioned below). Second of all, as other answers have said, you have to use print as a function now. That's the whole point of from __future__ import print_function; to bring the print function from Python 3 into Python 2.6+.

from __future__ import print_function

import sys, os, time

for x in range(0,10):
    print(x, sep=' ', end='')  # No need for sep here, but okay :)
    time.sleep(1)

__future__ statements need to be near the top of the file because they change fundamental things about the language, and so the compiler needs to know about them from the beginning. From the documentation:

A future statement is recognized and treated specially at compile time: Changes to the semantics of core constructs are often implemented by generating different code. It may even be the case that a new feature introduces new incompatible syntax (such as a new reserved word), in which case the compiler may need to parse the module differently. Such decisions cannot be pushed off until runtime.

The documentation also mentions that the only things that can precede a __future__ statement are the module docstring, comments, blank lines, and other future statements.

When setup a job in new windows you have two fields "program/script" and "Start in(Optional)". Put program name in first and program location in second. If you will not do that and your program start not in directory with exe, it will not find files that are located in it.

$scope.removeItem = function() {
    $scope.items.splice($scope.toRemove, 1);
    $scope.toRemove = null;
};

this works for me!

Whenever an array is created, its size is specified. So length can be considered as a construction attribute. For String, it essentially a char array. Length is a property of the char array. There is no need to put length as a field, because not everything needs this field. http://www.programcreek.com/2013/11/start-from-length-length-in-java/

read -r -p "Are you sure? [Y/n]" response
  response=${response,,} # tolower
  if [[ $response =~ ^(yes|y| ) ]] || [[ -z $response ]]; then
      your-action-here
  fi

The code you wrote will always return true because state cannot be both 10 and 15 for the statement to be false. if ((state != 10) && (state != 15).... AND is what you need not OR.

Use $.inArray instead. This returns the index of the element in the array.

JSFIDDLE DEMO

var statesArray = [10, 15, 19]; // list out all

var index = $.inArray(state, statesArray);

if(index == -1) {
    console.log("Not there in array");
    return true;

} else {
    console.log("Found it");
    return false;
}

That is SQL Server syntax for converting a date to a string. In MySQL you can use the DATE function to extract the date from a datetime:

SELECT *
FROM players
WHERE DATE(us_reg_date) BETWEEN '2000-07-05' AND '2011-11-10'

But if you want to take advantage of an index on the column us_reg_date you might want to try this instead:

SELECT *
FROM players
WHERE us_reg_date >= '2000-07-05'
  AND us_reg_date < '2011-11-10' + interval 1 day

orphanRemoval has nothing to do with ON DELETE CASCADE.

orphanRemoval is an entirely ORM-specific thing. It marks "child" entity to be removed when it's no longer referenced from the "parent" entity, e.g. when you remove the child entity from the corresponding collection of the parent entity.

ON DELETE CASCADE is a database-specific thing, it deletes the "child" row in the database when the "parent" row is deleted.

Just select the code and

• on Windows do Ctrl + Alt + L

• on Linux do Ctrl + Windows Key + Alt + L

• on Mac do CMD + Option + L

you can just append them on your formdata, add your files and datas in it.you can read this..

https://developer.mozilla.org/en-US/docs/Web/API/FormData/append

for better understanding. you can separately retrieve them $_FILES for your files and $_POST for your data.

To create a user with sudo privileges is to put the user into /etc/sudoers, or make the user a member of a group specified in /etc/sudoers. And to make it password-less is to additionally specify NOPASSWD in /etc/sudoers.

Example of /etc/sudoers:

## Allow root to run any commands anywhere
root    ALL=(ALL)       ALL

## Allows people in group wheel to run all commands
%wheel  ALL=(ALL)       ALL

## Same thing without a password
%wheel  ALL=(ALL)       NOPASSWD: ALL

And instead of fiddling with /etc/sudoers file, we can create a new file in /etc/sudoers.d/ directory since this directory is included by /etc/sudoers by default, which avoids the possibility of breaking existing sudoers file, and also eliminates the dependency on the content inside of /etc/sudoers.

To achieve above in Ansible, refer to the following:

- name: sudo without password for wheel group
  copy:
    content: '%wheel ALL=(ALL:ALL) NOPASSWD:ALL'
    dest: /etc/sudoers.d/wheel_nopasswd
    mode: 0440

You may replace %wheel with other group names like %sudoers or other user names like deployer.

This is what apps like quicken, ms money etc use.

Just another good looking table. I added "table-hover" class because it gives a nice hovering effect.

   <h3>NATO Phonetic Alphabet</h3>    
   <table class="table table-striped table-bordered table-condensed table-hover">
   <thead>
    <tr> 
        <th>Letter</th>
        <th>Phonetic Letter</th>

    </tr>
    </thead>
  <tr>
    <th>A</th>
    <th>Alpha</th>

  </tr>
  <tr>
    <td>B</td>
    <td>Bravo</td>

  </tr>
  <tr>
    <td>C</td>
    <td>Charlie</td>

  </tr>

Actually what you're asking for exists - however it's done as add-on modules. Check out this question on Better CSS in .NET for examples.

Check out Larsenal's answer on using LESS to get an idea of what these add-ons do.

First you should understand how localStorage works. you are doing wrong way to set/get values in local storage. Please read this for more information : How to Use Local Storage with JavaScript

If you want to remove unwanted space in UITableview you can use below two methods

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section{
    return 0.1;
}
- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section
{
    return 0.1;
}

Your usage is correct. I bet that your external program, flow.exe, needs to be executed in its directory, because it accesses some external files stored there.

So you might try:

import sys, string, os, arcgisscripting
os.chdir('c:\\documents and settings\\flow_model')
os.system('"C:\\Documents and Settings\\flow_model\\flow.exe"')

(Beware of the double quotes inside the single quotes...)

import pandas as pd
df = pd.read_csv('/PathToFile.txt', sep = ',')

This will import your .txt or .csv file into a DataFrame.

In Python-style regex, \d matches any individual digit. If you're seeing something that doesn't seem to do that, please provide the full regex you're using, as opposed to just describing that one particular symbol.

>>> import re
>>> re.match(r'\d', '3')
<_sre.SRE_Match object at 0x02155B80>
>>> re.match(r'\d', '2')
<_sre.SRE_Match object at 0x02155BB8>
>>> re.match(r'\d', '1')
<_sre.SRE_Match object at 0x02155B80>

Jquery.ajax does not encode POST data for you automatically the way that it does for GET data. Jquery expects your data to be pre-formated to append to the request body to be sent directly across the wire.

A solution is to use the jQuery.param function to build a query string that most scripts that process POST requests expect.

$.ajax({
    url: 'superman',
    type: 'POST',
    data: jQuery.param({ field1: "hello", field2 : "hello2"}) ,
    contentType: 'application/x-www-form-urlencoded; charset=UTF-8',
    success: function (response) {
        alert(response.status);
    },
    error: function () {
        alert("error");
    }
}); 

In this case the param method formats the data to:

field1=hello&field2=hello2

The Jquery.ajax documentation says that there is a flag called processData that controls whether this encoding is done automatically or not. The documentation says that it defaults to true, but that is not the behavior I observe when POST is used.

This worked on Sublime 3:

To browse html files with default app by Alt+L hotkey:

Add this line to Preferences -> Key Bindings - User opening file:

{ "keys": ["alt+l"], "command": "open_in_browser"}

To browse or open with external app like chrome:

Add this line to Tools -> Build System -> New Build System... opening file, and save with name "OpenWithChrome.sublime-build"

"shell_cmd": "C:\\PROGRA~1\\Google\\Chrome\\APPLIC~1\\chrome.exe $file"

Then you can browse/open the file by selecting Tools -> Build System -> OpenWithChrome and pressing F7 or Ctrl+B key.

Function ExtSql(ByVal sql As String) As Boolean

        cmd = New SqlCommand
        cmd.Connection = cnn

        cmd.CommandText = sql

I looked the above answers and found out that they are not good for my project because of licensing problems with GPL.

And I found out this: PyID3Lib, while that particular python binding release date is old, it uses the ID3Lib, which itself is up to date.

Notable to mention is that both are LGPL, and are good to go.

$(document).ready(function() {
    $('#example').dataTable( {
    "aLengthMenu": [[25, 50, 75, -1], [25, 50, 75, "All"]],
    "pageLength": 25
    } );
} );

aLengthMenu : This parameter allows you to readily specify the entries in the length drop down menu that DataTables shows when pagination is enabled. It can be either a 1D array of options which will be used for both the displayed option and the value, or a 2D array which will use the array in the first position as the value, and the array in the second position as the displayed options (useful for language strings such as 'All').

Update

Since DataTables v1.10, the options you are looking for are pageLength and lengthMenu

You was near:

this["instance_" + a] = function () {...};

{...};

GUID stands for Global Unique Identifier

In Brief: (the clue is in the name)

In Detail: GUIDs are designed to be unique; they are calculated using a random method based on the computers clock and computer itself, if you are creating many GUIDs at the same millisecond on the same machine it is possible they may match but for almost all normal operations they should be considered unique.

There looks to be an issue when the time of the phone/emulator is different to the one of the server (where react-native packager is running). In my case there was a 1 minute difference between the time of the phone and the computer. After synchronizing them (didn't do anything fancy, the phone was set on manual time, and I just set it to use the network(sim) provided time), everything worked fine. This github issue helped me find the problem.

Since some of you might have arrived at the question looking to specifically removing only undefined, you can use:

• a combination of Lodash methods

  _.omitBy(object, _.isUndefined)
  

• the rundef package, which removes only undefined properties

  rundef(object)
  

If you need to recursively remove undefined properties, the rundef package also has a recursive option.

rundef(object, false, true);

See the documentation for more details.

The function itself looks fine to me. The problem could be that you aren't allocating enough space for your string to pad that many characters onto it. You could avoid this problem in the future by passing a size_of_string argument to the function and make sure you don't pad the string when the length is about to be greater than the size.

for(int i = 0; i < getArray.size(); i++){
      Object object = getArray.get(i);
      // now do something with the Object
}

You need to check for the type:

The values can be any of these types: Boolean, JSONArray, JSONObject, Number, String, or the JSONObject.NULL object. [Source]

In your case, the elements will be of type JSONObject, so you need to cast to JSONObject and call JSONObject.names() to retrieve the individual keys.

Use CURRENT_TIMESTAMP (or GETDATE() on archaic versions of SQL Server).

The best method is what Mark Byers explains:

s = s.substring(0, s.length() - 1)

For example, if we want to replace \ to space " " with ReplaceAll, it doesn't work fine

String.replaceAll("\\", "");

or

String.replaceAll("\\$", "");   //if it is a path

None of the above solutions worked for me, in a YAML file within a Jekyll project. After trying many options, I realized that an HTML injection with <br> might do as well, since in the end everything is rendered to HTML:

name: | In a village of La Mancha <br> whose name I don't <br> want to remember.

At least it works for me. No idea on the problems associated to this approach.

You have an incompatibility between the version of ASM required by Hibernate (asm-1.5.3.jar) and the one required by Spring. But, actually, I wonder why you have asm-2.2.3.jar on your classpath (ASM is bundled in spring.jar and spring-core.jar to avoid such problems AFAIK). See HHH-2222.

This will prefix your files in their directory.

The ${f%/*} is the path till the last slash / -> the directory

The ${f##*/} is the text without anything before last slash / -> filename without the path

So that's how it goes:

for f in $(find /directory/ -type f); do 
  mv -v $f ${f%/*}/$(date +%Y%m%d)_Prefix_${f##*/}
done

IE 9 : If you want that the user takes a look at image before he posts it to the server : The user should ADD the website to "trusted Website list".

I think the differences can be put as the following:

• Cohesion represents the degree to which a part of a code base forms a logically single, atomic unit.
• Coupling represents the degree to which a single unit is independent from others.
• It’s impossible to archive full decoupling without damaging cohesion, and vice versa.

In this blog post I write about it in more detail.

This might work...

from p in db.products
    select new
    {
        Owner = (p.price > 0 ?
            from q in db.Users select q.Name :
            from r in db.ExternalUsers select r.Name)
    }

According to nginx documentation it supports custom values or even the exclusion:

Syntax: server_tokens on | off | build | string;

but sadly only with a commercial subscription:

Additionally, as part of our commercial subscription, starting from version 1.9.13 the signature on error pages and the “Server” response header field value can be set explicitly using the string with variables. An empty string disables the emission of the “Server” field.

For moving and overwriting files, it doesn't look like there is the -R option (when in doubt check your options by typing [your_cmd] --help. Also, this answer depends on how you want to move your file. Move all files, files & directories, replace files at destination, etc.

When you type in mv --help it returns the description of all options.

For mv, the syntax is mv [option] [file_source] [file_destination]

To move simple files: mv image.jpg folder/image.jpg

To move as folder into destination mv folder home/folder

To move all files in source to destination mv folder/* home/folder/

Use -v if you want to see what is being done: mv -v

Use -i to prompt before overwriting: mv -i

Use -u to update files in destination. It will only move source files newer than the file in the destination, and when it doesn't exist yet: mv -u

Tie options together like mv -viu, etc.

I used the answer given by Chase (answered May 11 '11 at 14:21), but I added a bit of code to apply that solution to my particular problem.

I had a frame of rates (user, download) and a frame of totals (user, download) to be merged by user, and I wanted to include every rate, even if there were no corresponding total. However, there could be no missing totals, in which case the selection of rows for replacement of NA by zero would fail.

The first line of code does the merge. The next two lines change the column names in the merged frame. The if statement replaces NA by zero, but only if there are rows with NA.

# merge rates and totals, replacing absent totals by zero
graphdata <- merge(rates, totals, by=c("user"),all.x=T)
colnames(graphdata)[colnames(graphdata)=="download.x"] = "download.rate"
colnames(graphdata)[colnames(graphdata)=="download.y"] = "download.total"
if(any(is.na(graphdata$download.total))) {
    graphdata[is.na(graphdata$download.total),]$download.total <- 0
}

Try Case

SELECT   stock.name,
      CASE 
         WHEN stock.quantity <20 THEN 'Buy urgent'
         ELSE 'There is enough'
      END
FROM stock

The preferred way is to always use the literal syntax with square brackets; its behaviour is predictable for any number of items, unlike Array's. What's more, Array is not a keyword, and although it is not a realistic situation, someone could easily overwrite it:

function Array() { return []; }

alert(Array(1, 2, 3)); // An empty alert box

However, the larger issue is that of consistency. Someone refactoring code could come across this function:

function fetchValue(n) {
    var arr = new Array(1, 2, 3);

    return arr[n];
}

As it turns out, only fetchValue(0) is ever needed, so the programmer drops the other elements and breaks the code, because it now returns undefined:

var arr = new Array(1);

If your class is non-activity class, and creating an instance of it from the activiy, you can pass an instance of context via constructor of the later as follows:

class YourNonActivityClass{

// variable to hold context
private Context context;

//save the context recievied via constructor in a local variable

public YourNonActivityClass(Context context){
    this.context=context;
}

}

You can create instance of this class from the activity as follows:

new YourNonActivityClass(this);

Help from @phil-frost was very helpful, was exactly what I was looking for.

I have made few tweaks after that so I'm would like to share it here:

def csv_as_dict(file, ref_header, delimiter=None):

    import csv
    if not delimiter:
        delimiter = ';'
    reader = csv.DictReader(open(file), delimiter=delimiter)
    result = {}
    for row in reader:
        print(row)
        key = row.pop(ref_header)
        if key in result:
            # implement your duplicate row handling here
            pass
        result[key] = row
    return result

You can call it:

myvar = csv_as_dict(csv_file, 'ref_column')

Where ref_colum will be your main key for each row.

The amount of hacks you would need to go through to completely hide the fact your site is built by Meteor.js is absolutely ridiculous. You would have to strip essentially all core functionality and just serve straight up html, completely defeating the purpose of using the framework anyway.

That being said, I suggest looking at buildwith.com

You enter a url, and it reveals a ton of information about a site. If you only need to "fool" engines like this, there may be simple solutions.

I fixed this by checking Delete all existing files prior to publish in Visual Studio:

I set the content-type in the MarshallingView in the ContentNegotiatingViewResolver bean. It works easily, clean and smoothly:

<property name="defaultViews">
  <list>
    <bean class="org.springframework.web.servlet.view.xml.MarshallingView">
      <constructor-arg>
        <bean class="org.springframework.oxm.xstream.XStreamMarshaller" />     
      </constructor-arg>
      <property name="contentType" value="application/xml;charset=UTF-8" />
    </bean>
  </list>
</property>

In you app config file change the url to localhost/example/public

Then when you want to link to something

<a href="{{ url('page') }}">Some Text</a>

without blade

<a href="<?php echo url('page') ?>">Some Text</a>

Like this add position:fixed; and bottom:0; below the selector #footer:

demo

CSS

#footer {
    background-color: #F3F3F3;
    padding-top: 10px;
    padding-bottom: 0px;
    position:fixed;
    bottom:0;
    width:100%;
}

It is just called the eyedropper tool. There is no shortcut key for it that I'm aware of. The only way you can use it now is by clicking on the color picker box in styles sidebar and then clicking on the page as you have already been doing.

Native way to get the mimetype:

For PHP < 5.3 use mime_content_type()
For PHP >= 5.3 use finfo_open() or mime_content_type()

Alternatives to get the MimeType are exif_imagetype and getimagesize, but these rely on having the appropriate libs installed. In addition, they will likely just return image mimetypes, instead of the whole list given in magic.mime.

While mime_content_type is available from PHP 4.3 and is part of the FileInfo extension (which is enabled by default since PHP 5.3, except for Windows platforms, where it must be enabled manually, for details see here).

If you don't want to bother about what is available on your system, just wrap all four functions into a proxy method that delegates the function call to whatever is available, e.g.

function getMimeType($filename)
{
    $mimetype = false;
    if(function_exists('finfo_open')) {
        // open with FileInfo
    } elseif(function_exists('getimagesize')) {
        // open with GD
    } elseif(function_exists('exif_imagetype')) {
       // open with EXIF
    } elseif(function_exists('mime_content_type')) {
       $mimetype = mime_content_type($filename);
    }
    return $mimetype;
}

First()

When you know that result contain more than 1 element expected and you should only the first element of sequence.

FirstOrDefault()

FirstOrDefault() is just like First() except that, if no element match the specified condition than it returns default value of underlying type of generic collection. It does not throw InvalidOperationException if no element found. But collection of element or a sequence is null than it throws an exception.

It's a matter of preference, but I prefer to see scripts that consistently use the slash - this way all "units" of work (creating a PL/SQL object, running a PL/SQL anonymous block, and executing a DML statement) can be picked out more easily by eye.

Also, if you eventually move to something like Ant for deployment it will simplify the definition of targets to have a consistent statement delimiter.

strip only strips characters from the very front and back of the string.

To delete a list of characters, you could use the string's translate method:

import string
name = "Barack (of Washington)"
table = string.maketrans( '', '', )
print name.translate(table,"(){}<>")
# Barack of Washington

For debug/release flags, see the CMAKE_BUILD_TYPE variable (you pass it as cmake -DCMAKE_BUILD_TYPE=value). It takes values like Release, Debug, etc.

https://gitlab.kitware.com/cmake/community/wikis/doc/cmake/Useful-Variables#compilers-and-tools

cmake uses the extension to choose the compiler, so just name your files .c.

You can override this with various settings:

For example:

set_source_files_properties(yourfile.c LANGUAGE CXX) 

Would compile .c files with g++. The link above also shows how to select a specific compiler for C/C++.

Answer : I found this and wants to share it with you.

Sub Copier4()
   Dim x As Integer

   For x = 1 To ActiveWorkbook.Sheets.Count
      'Loop through each of the sheets in the workbook
      'by using x as the sheet index number.
      ActiveWorkbook.Sheets(x).Copy _
         After:=ActiveWorkbook.Sheets(ActiveWorkbook.Sheets.Count)
         'Puts all copies after the last existing sheet.
   Next
End Sub

But the question, can we use it with following code to rename the sheets, if yes, how can we do so?

Sub CreateSheetsFromAList()
Dim MyCell As Range, MyRange As Range
Set MyRange = Sheets("Summary").Range("A10")
Set MyRange = Range(MyRange, MyRange.End(xlDown))
For Each MyCell In MyRange
Sheets.Add After:=Sheets(Sheets.Count) 'creates a new worksheet
Sheets(Sheets.Count).Name = MyCell.Value ' renames the new worksheet
Next MyCell
End Sub

This is the quickest way to solve the problem but it's not recommended because its applicable only for your local system.

This is more of an IDE feature than a language feature. Netbeans allows you to define your own folding definitions using the following definition:

// <editor-fold defaultstate="collapsed" desc="user-description">
  ...any code...
// </editor-fold>

As noted in the article, this may be supported by other editors too, but there are no guarantees.

This can be done using:

plt.figure(figsize=(15,8))
sns.kdeplot(data,shade=True)

As long as people still stuck in this issue and we are in 2020 already. I get a pure CSS solution by giving the drop down menu a flex display

this snippet works great with datatable-scroll-wrap class

.datatable-scroll-wrap .dropdown.dropup.open .dropdown-menu {
    display: flex;
}
.datatable-scroll-wrap .dropdown.dropup.open .dropdown-menu li a {
    display: flex;
}

The only good way I found was to use Javascript to move a tooltip <div> around. Obviously this only works if you have SVG inside an HTML document - not standalone. And it requires Javascript.

function showTooltip(evt, text) {_x000D_
  let tooltip = document.getElementById("tooltip");_x000D_
  tooltip.innerHTML = text;_x000D_
  tooltip.style.display = "block";_x000D_
  tooltip.style.left = evt.pageX + 10 + 'px';_x000D_
  tooltip.style.top = evt.pageY + 10 + 'px';_x000D_
}_x000D_
_x000D_
function hideTooltip() {_x000D_
  var tooltip = document.getElementById("tooltip");_x000D_
  tooltip.style.display = "none";_x000D_
}

#tooltip {_x000D_
  background: cornsilk;_x000D_
  border: 1px solid black;_x000D_
  border-radius: 5px;_x000D_
  padding: 5px;_x000D_
}

<div id="tooltip" display="none" style="position: absolute; display: none;"></div>_x000D_
_x000D_
<svg>_x000D_
  <rect width="100" height="50" style="fill: blue;" onmousemove="showTooltip(evt, 'This is blue');" onmouseout="hideTooltip();" >_x000D_
  </rect>_x000D_
</svg>

For those who uses an opener, you can achieve the same thing based on Enno Gröper's great answer:

import urllib2, ssl

ctx = ssl.create_default_context()
ctx.check_hostname = False
ctx.verify_mode = ssl.CERT_NONE

opener = urllib2.build_opener(urllib2.HTTPSHandler(context=ctx), your_first_handler, your_second_handler[...])
opener.addheaders = [('Referer', 'http://example.org/blah.html')]

content = opener.open("https://localhost/").read()

And then use it as before.

According to build_opener and HTTPSHandler, a HTTPSHandler is added if ssl module exists, here we just specify our own instead of the default one.

Add following to your web.config under appSettings:

<add key="LogPath" value="C:\\logpath" />

It should create log file in the folder LogPath with request and response XML.

In old school JavaScript, you could do this:

document.body.innerHTML = '<p id="foo">Some HTML</p>' + document.body.innerHTML;

In response to your comment:

[...] I was interested in declaring the source of a new element's attributes and events, not the innerHTML of an element.

You need to inject the new HTML into the DOM, though; that's why innerHTML is used in the old school JavaScript example. The innerHTML of the BODY element is prepended with the new HTML. We're not really touching the existing HTML inside the BODY.

I'll rewrite the abovementioned example to clarify this:

var newElement = '<p id="foo">This is some dynamically added HTML. Yay!</p>';
var bodyElement = document.body;
bodyElement.innerHTML = newElement + bodyElement.innerHTML;
// note that += cannot be used here; this would result in 'NaN'

Using a JavaScript framework would make this code much less verbose and improve readability. For example, jQuery allows you to do the following:

$('body').prepend('<p id="foo">Some HTML</p>');

Try this one, and then import the package:

import org.openqa.selenium.Keys;

driver.findElement(By.xpath("//*[@id='username']")).sendKeys("username");

driver.findElement(By.xpath("//*[@id='username']")).sendKeys(Keys.TAB);

driver.findElement(By.xpath("//*[@id='Password']")).sendKeys("password");

What C has over a good macro assembler is the language C. Type checking. Loop constructs. Automatic stack management. (Nearly) automatic variable management. Dynamic memory techniques in assembler are a massive pain in the butt. Doing a linked list properly is just down right scary compared to C or better yet list foo.insert(). And debugging - well, there's no contest on what is easier to debug. HLLs win hands down there.

I've coded nearly half my career in assembler which makes it very easy for me to think in assmebler. it helps me to see what the C compiler is doing which again helps me write code that the C compiler can efficiently handle. A well thought out routine written in C can be written to output exactly what you want in assembler with a little work - and it's portable! I've already had to rewrite a few older asm routines back to C for cross platform reasons and it's no fun.

No, I'll stick with C and deal with the occasional slight slowdown in performance against the productivity time I gain with HLL.

It would help if you provided the error you are seeing. Look at http://docs.oracle.com/javase/7/docs/api/java/lang/Math.html and you will see that max only returns the max between two numbers, so likely you code is not even compiling.

Solve all your compilation errors first.

Then your homework will consist of finding the max of three numbers by comparing the first two together, and comparing that max result with the third value. You should have enough to find your answer now.

char ch = 't';
char chArray[2];
sprintf(chArray, "%c", ch);
char chOutput[10]="tes";
strcat(chOutput, chArray);
cout<<chOutput;

OUTPUT:

test

ping (ICMP protocol) and ssh are two different protocols.

1. It could be that ssh service is not running or not installed

2. firewall restriction (local to server like iptables or even sshd config lock down ) or (external firewall that protects incomming traffic to network hosting 111.111.111.111)

First check is to see if ssh port is up

nc -v -w 1 111.111.111.111 -z 22

if it succeeds then ssh should communicate if not then it will never work until restriction is lifted or ssh is started

Using figure environment and .set_clim()

Could be easier and safer this alternative if you have multiple plots:

import matplotlib as m
import matplotlib.pyplot as plt
import numpy as np

cdict = {
  'red'  :  ( (0.0, 0.25, .25), (0.02, .59, .59), (1., 1., 1.)),
  'green':  ( (0.0, 0.0, 0.0), (0.02, .45, .45), (1., .97, .97)),
  'blue' :  ( (0.0, 1.0, 1.0), (0.02, .75, .75), (1., 0.45, 0.45))
}

cm = m.colors.LinearSegmentedColormap('my_colormap', cdict, 1024)

x = np.arange(0, 10, .1)
y = np.arange(0, 10, .1)
X, Y = np.meshgrid(x,y)

data = 2*( np.sin(X) + np.sin(3*Y) )
data1 = np.clip(data,0,6)
data2 = np.clip(data,-6,0)
vmin = np.min(np.array([data,data1,data2]))
vmax = np.max(np.array([data,data1,data2]))

fig = plt.figure()
ax = fig.add_subplot(131)
mesh = ax.pcolormesh(data, cmap = cm)
mesh.set_clim(vmin,vmax)
ax1 = fig.add_subplot(132)
mesh1 = ax1.pcolormesh(data1, cmap = cm)
mesh1.set_clim(vmin,vmax)
ax2 = fig.add_subplot(133)
mesh2 = ax2.pcolormesh(data2, cmap = cm)
mesh2.set_clim(vmin,vmax)
# Visualizing colorbar part -start
fig.colorbar(mesh,ax=ax)
fig.colorbar(mesh1,ax=ax1)
fig.colorbar(mesh2,ax=ax2)
fig.tight_layout()
# Visualizing colorbar part -end

plt.show()

A single colorbar

The best alternative is then to use a single color bar for the entire plot. There are different ways to do that, this tutorial is very useful for understanding the best option. I prefer this solution that you can simply copy and paste instead of the previous visualizing colorbar part of the code.

fig.subplots_adjust(bottom=0.1, top=0.9, left=0.1, right=0.8,
                    wspace=0.4, hspace=0.1)
cb_ax = fig.add_axes([0.83, 0.1, 0.02, 0.8])
cbar = fig.colorbar(mesh, cax=cb_ax)

P.S.

I would suggest using pcolormesh instead of pcolor because it is faster (more infos here ).

I was solving same problem recently. I was designing a write cmdlet for my Subtitle module. I had six different user stories:

• Subtitle only
• Subtitle and path (original file name is used)
• Subtitle and new file name (original path is used)
• Subtitle and name suffix is used (original path and modified name is used).
• Subtile, new path and new file name is is used.
• Subtitle, new path and suffix is used.

I end up in the big frustration because I though that 4 parameters will be enough. Like most of the times, the frustration was pointless because it was my fault. I didn't know enough about parameter sets.

After some research in documentation, I realized where is the problem. With knowledge how the parameter sets should be used, I developed a general and simple approach how to solve this problem. A pencil and a sheet of paper is required but a spreadsheet editor is better:

1. Write down all intended ways how the cmdlet should be used => user stories.
2. Keep adding parameters with meaningful names and mark the use of the parameters until you have a unique collection set => no repetitive combination of parameters.
3. Implement parameter sets into your code.
4. Prepare tests for all possible user stories.
5. Run tests (big surprise, right?). IDEs doesn't checks parameter sets collision, tests could save lots of trouble later one.

Example:

The practical example could be seen over here.

BTW: The parameter uniqueness within parameter sets is the reason why the ParameterSetName property doesn't support [String[]]. It doesn't really make any sense.

Check if you're really using EnvDTE reference. If not, remove it and recompile.

The simplest way to do this is:

git tag v1.0.0 f4ba1fc
git push origin --tags

with f4ba1fc being the beginning of the hash of the commit you want to tag and v1.0.0 being the version you want to tag.

prop.table is a nice friendly way of obtaining proportions of tables.

m <- matrix(1:4,2)

 m
     [,1] [,2]
[1,]    1    3
[2,]    2    4

Leaving margin blank gives you proportions of the whole table

 prop.table(m, margin=NULL)
     [,1] [,2]
[1,]  0.1  0.3
[2,]  0.2  0.4

Giving it 1 gives you row proportions

 prop.table(m, 1)
      [,1]      [,2]
[1,] 0.2500000 0.7500000
[2,] 0.3333333 0.6666667

And 2 is column proportions

 prop.table(m, 2)
          [,1]      [,2]
[1,] 0.3333333 0.4285714
[2,] 0.6666667 0.5714286

You can do it with the HTMLWorker class (deprecated) like this:

import com.itextpdf.text.html.simpleparser.HTMLWorker;
//...
try {
    String k = "<html><body> This is my Project </body></html>";
    OutputStream file = new FileOutputStream(new File("C:\\Test.pdf"));
    Document document = new Document();
    PdfWriter.getInstance(document, file);
    document.open();
    HTMLWorker htmlWorker = new HTMLWorker(document);
    htmlWorker.parse(new StringReader(k));
    document.close();
    file.close();
} catch (Exception e) {
    e.printStackTrace();
}

or using the XMLWorker, (download from this jar) using this code:

import com.itextpdf.tool.xml.XMLWorkerHelper;
//...
try {
    String k = "<html><body> This is my Project </body></html>";
    OutputStream file = new FileOutputStream(new File("C:\\Test.pdf"));
    Document document = new Document();
    PdfWriter writer = PdfWriter.getInstance(document, file);
    document.open();
    InputStream is = new ByteArrayInputStream(k.getBytes());
    XMLWorkerHelper.getInstance().parseXHtml(writer, document, is);
    document.close();
    file.close();
} catch (Exception e) {
    e.printStackTrace();
}

In your controller, you are using an http scheme, but I think you should be using a ws scheme, as you are using websockets. Try to use ws://localhost:3000 in your connect function.

What about something like this:

for /f %%f in ('curl -s -l -u user:pass ftp://ftp.myftpsite.com/') do curl -O -u user:pass ftp://ftp.myftpsite.com/%%f

If you are using the bash exit code status $? as variable, it's better to do this:

if [ $? -eq 4 -o $? -eq 8 ] ; then  
   echo "..."
fi

Because if you do:

if [ $? -eq 4 ] || [ $? -eq 8 ] ; then  

The left part of the OR alters the $? variable, so the right part of the OR doesn't have the original $? value.

    @Override

Alternatively, you can create a getter method for text.

You can now do Strings.STRING_ONE.toString();

This should do what you need

Try to save result of Select statement in separate variable and then use that for delete query.

please set dataType config property in your ajax call and give it another try!

another point is you are using ajax call setup configuration properties as string and it is wrong as reference site

$.ajax({

    url : 'http://voicebunny.comeze.com/index.php',
    type : 'GET',
    data : {
        'numberOfWords' : 10
    },
    dataType:'json',
    success : function(data) {              
        alert('Data: '+data);
    },
    error : function(request,error)
    {
        alert("Request: "+JSON.stringify(request));
    }
});

I hope be helpful!

Here is the simplest explanation

Alan Turing created a machine that can take a program, run that program, and show some result. But then he had to create different machines for different programs. So he created "Universal Turing Machine" that can take ANY program and run it.

Programming languages are similar to those machines (although virtual). They take programs and run them. Now, a programing language is called "Turing complete", if it can run any program (irrespective of the language) that a Turing machine can run given enough time and memory.

For example: Let's say there is a program that takes 10 numbers and adds them. A Turing machine can easily run this program. But now imagine that for some reason your programming language can't perform the same addition. This would make it "Turing incomplete" (so to speak). On the other hand, if it can run any program that the universal Turing machine can run, then it's Turing complete.

Most modern programming languages (e.g. Java, JavaScript, Perl, etc.) are all Turing complete because they each implement all the features required to run programs like addition, multiplication, if-else condition, return statements, ways to store/retrieve/erase data and so on.

Update: You can learn more on my blog post: "JavaScript Is Turing Complete" — Explained

It is not enough to change distributionUrl in gradle-wrapper.properties, you also need to change gradle version in your project structure.

1. Go to gradle-wrapper.properties and change:

distributionUrl=https://services.gradle.org/distributions/gradle-6.8-all.zip

2. Go to Android studio -> file -> project structure

Change gradle verison to 6.8 or whatever verison you selected that is compatible with your jdk.

This could also happens if you put a @PreAuthorize or @PostAuthorize in a Bean in creation. I would recommend to move such annotations to methods of interest.

My solution to the problem is the following. You can find the function http_digest_parse , $realm and $users in the second example of this page: http://php.net/manual/en/features.http-auth.php.

session_start();

function LogOut() {
  session_destroy();
  session_unset($_SESSION['session_id']);
  session_unset($_SESSION['logged']);

  header("Location: /", TRUE, 301);   
}

function Login(){

  global $realm;

  if (empty($_SESSION['session_id'])) {
    session_regenerate_id();
    $_SESSION['session_id'] = session_id();
  }

  if (!IsAuthenticated()) {  
    header('HTTP/1.1 401 Unauthorized');
    header('WWW-Authenticate: Digest realm="'.$realm.
   '",qop="auth",nonce="'.$_SESSION['session_id'].'",opaque="'.md5($realm).'"');
    $_SESSION['logged'] = False;
    die('Access denied.');
  }
  $_SESSION['logged'] = True;  
}

function IsAuthenticated(){
  global $realm;
  global $users;


  if  (empty($_SERVER['PHP_AUTH_DIGEST']))
      return False;

  // check PHP_AUTH_DIGEST
  if (!($data = http_digest_parse($_SERVER['PHP_AUTH_DIGEST'])) ||
     !isset($users[$data['username']]))
     return False;// invalid username


  $A1 = md5($data['username'] . ':' . $realm . ':' . $users[$data['username']]);
  $A2 = md5($_SERVER['REQUEST_METHOD'].':'.$data['uri']);

  // Give session id instead of data['nonce']
  $valid_response =   md5($A1.':'.$_SESSION['session_id'].':'.$data['nc'].':'.$data['cnonce'].':'.$data['qop'].':'.$A2);

  if ($data['response'] != $valid_response)
    return False;

  return True;
}

su - root

Goto /etc/ssh/sshd_config

vi sshd_config

Authentication:

PermitRootLogin yes

To enable empty passwords, change to yes (NOT RECOMMENDED)

PermitEmptyPasswords no

Change to no to disable tunnelled clear text passwords

PasswordAuthentication yes

:x!

Then restart ssh service

root@cloudera2:/etc/ssh# service ssh restart
ssh stop/waiting
ssh start/running, process 10978

Now goto sudoers files (/etc/sudoers).

User privilege specification

root  ALL=(ALL)NOPASSWD:ALL
yourinstanceuser  ALL=(ALL)NOPASSWD:ALL    / This is the user by which you are launching instance.

Just use 0.0.0.0/0.

host    all             all             0.0.0.0/0            md5

Make sure the listen_addresses in postgresql.conf (or ALTER SYSTEM SET) allows incoming connections on all available IP interfaces.

listen_addresses = '*'

After the changes you have to reload the configuration. One way to do this is execute this SELECT as a superuser.

SELECT pg_reload_conf();

Note: to change listen_addresses, a reload is not enough, and you have to restart the server.

The "scalability issues" for Hashtable are present in exactly the same way in Collections.synchronizedMap(Map) - they use very simple synchronization, which means that only one thread can access the map at the same time.

This is not much of an issue when you have simple inserts and lookups (unless you do it extremely intensively), but becomes a big problem when you need to iterate over the entire Map, which can take a long time for a large Map - while one thread does that, all others have to wait if they want to insert or lookup anything.

The ConcurrentHashMap uses very sophisticated techniques to reduce the need for synchronization and allow parallel read access by multiple threads without synchronization and, more importantly, provides an Iterator that requires no synchronization and even allows the Map to be modified during interation (though it makes no guarantees whether or not elements that were inserted during iteration will be returned).

On a related note: the java compiler uses int to represent boolean since JVM has a limited support for the boolean type.See Section 3.3.4 The boolean type.

In JVM, the integer zero represents false, and any non-zero integer represents true (Source : Inside Java Virtual Machine by Bill Venners)

This worked for me:

$('#fileInput').val('');

Not plumbing, but I have these in my .gitconfig:

lsum = log -n 1 --pretty=format:'%s'
lmsg = log -n 1 --pretty=format:'%s%n%n%b'

That's "last summary" and "last message". You can provide a commit to get the summary or message of that commit. (I'm using 1.7.0.5 so don't have %B.)

actually you should only put in-line elements inside the p, so in your case ol is better outside

Probably, not the cleanest solution, but it is definitely simpler than removing one-by-one:

document.getElementById("DropList").innerHTML = "";

Just in case anyone is interested, heres a complete Java module gradle file that correctly generates and references the built artefacts within an Android multi module application

buildscript {
    repositories {
        maven {
            url "https://plugins.gradle.org/m2/"
        }
    }
    dependencies {
        classpath "net.ltgt.gradle:gradle-apt-plugin:0.15"
    }
}

apply plugin: "net.ltgt.apt"
apply plugin: "java-library"
apply plugin: "idea"

idea {
    module {
        sourceDirs += file("$buildDir/generated/source/apt/main")
        testSourceDirs += file("$buildDir/generated/source/apt/test")
    }
}

dependencies {

    // Dagger 2 and Compiler
    compile "com.google.dagger:dagger:2.15"
    apt "com.google.dagger:dagger-compiler:2.15"
    compile "com.google.guava:guava:24.1-jre"

}

sourceCompatibility = "1.8"
targetCompatibility = "1.8"

so I also had the same problem. This is probably happening because your computer has an older version of ruby. So you need to first update your ruby. Mine worked for ruby 2.6.3 version.I got this solution from sStackOverflow,

You need to first open terminal and put this code

curl -L https://get.rvm.io | bash -s stable

Then put this command

rvm install ruby-2.6

This would install the ruby for you if it hasn' t been installed.After this just update the ruby to the new version

rvm use ruby-2.6.3

After this just make ruby 2.6.3 your default

rvm --default use 2.6.3

This would possibly fix your issue. You can now put the command

sudo gem install cocoapods

And the command

pod setup

I hope this was useful

You must check this: Docblock Comment standards

http://pear.php.net/manual/en/standards.sample.php

The following works for me:

?rel=0&fs=0&showinfo=0

probably this sample could help:

  WebView lWebView = (WebView)findViewById(R.id.webView);
  File lFile = new File(Environment.getExternalStorageDirectory() + "<FOLDER_PATH_TO_FILE>/<FILE_NAME>");
  lWebView.loadUrl("file:///" + lFile.getAbsolutePath());

Your problem is comparable to the creation of a file object and opening the file. In fact there are a lot of classes where you have to perform two steps before you can actually use the object: create + Initialize (often called something similar to Open).

The advantage of this is that the constructor can be lightweight. If desired, you can change some properties before actually initializing the object. When all properties are set, the Initialize/Open function is called to prepare the object to be used. This Initialize function can be async.

The disadvantage is that you have to trust the user of your class that he will call Initialize() before he uses any other function of your class. In fact if you want to make your class full proof (fool proof?) you have to check in every function that the Initialize() has been called.

The pattern to make this easier is to declare the constructor private and make a public static function that will construct the object and call Initialize() before returning the constructed object. This way you'll know that everyone who has access to the object has used the Initialize function.

The example shows a class that mimics your desired async constructor

public MyClass
{
    public static async Task<MyClass> CreateAsync(...)
    {
        MyClass x = new MyClass();
        await x.InitializeAsync(...)
        return x;
    }

    // make sure no one but the Create function can call the constructor:
    private MyClass(){}

    private async Task InitializeAsync(...)
    {
        // do the async things you wanted to do in your async constructor
    }

    public async Task<int> OtherFunctionAsync(int a, int b)
    {
        return await ... // return something useful
    }

Usage will be as follows:

public async Task<int> SomethingAsync()
{
    // Create and initialize a MyClass object
    MyClass myObject = await MyClass.CreateAsync(...);

    // use the created object:
    return await myObject.OtherFunctionAsync(4, 7);
}

For me, only these steps could help me setting the root password on version 8.0.19:

mysql
SELECT user,authentication_string FROM mysql.user;
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'your_pass_here';
FLUSH PRIVILEGES;
SELECT user,authentication_string FROM mysql.user;

If you can see changes for the root user, then it works. Source: https://www.digitalocean.com/community/questions/can-t-set-root-password-mysql-server

In Swift you would do it like this:

    label.lineBreakMode = NSLineBreakMode.ByWordWrapping
    label.numberOfLines = 0

(Note that the way the lineBreakMode constant works is different to in ObjC)

public class RemoveExtraSpacesEfficient {

    public static void main(String[] args) {

        String s = "my    name is    mr    space ";

        char[] charArray = s.toCharArray();

        char prev = s.charAt(0);

        for (int i = 0; i < charArray.length; i++) {
            char cur = charArray[i];
            if (cur == ' ' && prev == ' ') {

            } else {
                System.out.print(cur);
            }
            prev = cur;
        }
    }
}

The above solution is the algorithm with the complexity of O(n) without using any java function.

I have benchmarked these various technics under Python 3.7.0 (IPython).

TLDR

• fastest (when the split symbol c is known): pre-compiled regex.
• fastest (otherwise): s.partition(c)[0].
• safe (i.e., when c may not be in s): partition, split.
• unsafe: index, regex.

Code

import string, random, re

SYMBOLS = string.ascii_uppercase + string.digits
SIZE = 100

def create_test_set(string_length):
    for _ in range(SIZE):
        random_string = ''.join(random.choices(SYMBOLS, k=string_length))
        yield (random.choice(random_string), random_string)

for string_length in (2**4, 2**8, 2**16, 2**32):
    print("\nString length:", string_length)
    print("  regex (compiled):", end=" ")
    test_set_for_regex = ((re.compile("(.*?)" + c).match, s) for (c, s) in test_set)
    %timeit [re_match(s).group() for (re_match, s) in test_set_for_regex]
    test_set = list(create_test_set(16))
    print("  partition:       ", end=" ")
    %timeit [s.partition(c)[0] for (c, s) in test_set]
    print("  index:           ", end=" ")
    %timeit [s[:s.index(c)] for (c, s) in test_set]
    print("  split (limited): ", end=" ")
    %timeit [s.split(c, 1)[0] for (c, s) in test_set]
    print("  split:           ", end=" ")
    %timeit [s.split(c)[0] for (c, s) in test_set]
    print("  regex:           ", end=" ")
    %timeit [re.match("(.*?)" + c, s).group() for (c, s) in test_set]

What is it?

WAI-ARIA stands for “Web Accessibility Initiative – Accessible Rich Internet Applications”. It is a set of attributes to help enhance the semantics of a web site or web application to help assistive technologies, such as screen readers for the blind, make sense of certain things that are not native to HTML. The information exposed can range from something as simple as telling a screen reader that activating a link or button just showed or hid more items, to widgets as complex as whole menu systems or hierarchical tree views.

This is achieved by applying roles and state attributes to HTML 4.01 or later markup that has no bearing on layout or browser functionality, but provides additional information for assistive technologies.

One corner stone of WAI-ARIA is the role attribute. It tells the browser to tell the assistive technology that the HTML element used is not actually what the element name suggests, but something else. While it originally is only a div element, this div element may be the container to a list of auto-complete items, in which case a role of “listbox” would be appropriate to use. Likewise, another div that is a child of that container div, and which contains a single option item, should then get a role of “option”. Two divs, but through the roles, totally different meaning. The roles are modeled after commonly used desktop application counterparts.

An exception to this are document landmark roles, which don’t change the actual meaning of the element in question, but provide information about this particular place in a document.

The second corner stone are WAI-ARIA states and properties. They define the state of certain native or WAI-ARIA elements such as if something is collapsed or expanded, a form element is required, something has a popup menu attached to it or the like. These are often dynamic and change their values throughout the lifecycle of a web application, and are usually manipulated via JavaScript.

What is it not?

WAI-ARIA is not intended to influence browser behavior. Unlike a real button element, for example, a div which you pour the role of “button” onto does not give you keyboard focusability, an automatic click handler when Space or Enter are being pressed on it, and other properties that are indiginous to a button. The browser itself does not know that a div with role of “button” is a button, only its accessibility API portion does.

As a consequence, this means that you absolutely have to implement keyboard navigation, focusability and other behavioural patterns known from desktop applications yourself. You can find some Advanced ARIA techniques Here.

When should I not use it?

Yes, that’s correct, this section comes first! Because the first rule of using WAI-ARIA is: Don’t use it unless you absolutely have to! The less WAI-ARIA you have, and the more you can count on using native HTML widgets, the better! There are some more rules to follow, you can check them out here.

Give them all a name that is the same

For example

<input type="button" value="a" name="btn" onclick="a" />
<input type="button" value="b" name="btn" onclick="b" />

Then in your php use:

$val = $_POST['btn']

Edit, as BalusC said; If you're not going to use onclick for doing any javascript (for example, sending the form) then get rid of it and use type="submit"

If you're on Windows, they are installed with the platform SDK (or Visual Studio). However the header files are only compatible with OpenGL 1.1. You need to create function pointers for new functionality it later versions. Can you please clarify what version of OpenGL you're trying to use.

Go to the traffic section inside graphs. Here you can find how many unique visitors you have. Other than this there is no other way to know who exactly viewed your account.

No, only use semicolons when they're required.

Yes.

KVO requires dynamic dispatch, so you simply need to add the dynamic modifier to a method, property, subscript, or initializer:

dynamic var foo = 0

The dynamic modifier ensures that references to the declaration will be dynamically dispatched and accessed through objc_msgSend.

Use the border-spacing property on the table element to set the spacing between cells.

Make sure border-collapse is set to separate (or there will be a single border between each cell instead of a separate border around each one that can have spacing between them).

Use a white space to match all descendants of an element:

div.dropdown * {
    color: red;
}

x y matches every element y that is inside x, however deeply nested it may be - children, grandchildren and so on.

The asterisk * matches any element.

What I did was download the JDK from here, start a windows command prompt (windows+r CMD) and set the environment variable JAVA_HOME to c:\Program Files\Java\jdk-14 with:

set JAVA_HOME="c:\Program Files\Java\jdk-14"

Then run what I wanted to run. It failed afterwards, but on a different issue.

classname.getResourceAsStream() loads a file via the classloader of classname. If the class came from a jar file, that is where the resource will be loaded from.

FileInputStream is used to read a file from the filesystem.

This is really easy using jQuery.

For instance:

$(".left").mouseover(function(){$(".left1").show()});
$(".left").mouseout(function(){$(".left1").hide()});

I've update your fiddle: http://jsfiddle.net/TqDe9/2/

To remove spaces from left/right, use LTRIM/RTRIM. What you had

UPDATE *tablename*
   SET *columnname* = LTRIM(RTRIM(*columnname*));

would have worked on ALL the rows. To minimize updates if you don't need to update, the update code is unchanged, but the LIKE expression in the WHERE clause would have been

UPDATE [tablename]
   SET [columnname] = LTRIM(RTRIM([columnname]))
 WHERE 32 in (ASCII([columname]), ASCII(REVERSE([columname])));

Note: 32 is the ascii code for the space character.

SELECT t.ID, 
       t.NAME, 
       (SELECT t1.SOMECOLUMN 
        FROM   TABLEB t1 
        WHERE  t1.F_ID = T.TABLEA.ID) 
FROM   TABLEA t; 

This will work for selecting from different table using sub query.

Alternatively, you can use requests.Session and observe cookies before and after a request:

>>> import requests
>>> session = requests.Session()
>>> print(session.cookies.get_dict())
{}
>>> response = session.get('http://google.com')
>>> print(session.cookies.get_dict())
{'PREF': 'ID=5514c728c9215a9a:FF=0:TM=1406958091:LM=1406958091:S=KfAG0U9jYhrB0XNf', 'NID': '67=TVMYiq2wLMNvJi5SiaONeIQVNqxSc2RAwVrCnuYgTQYAHIZAGESHHPL0xsyM9EMpluLDQgaj3db_V37NjvshV-eoQdA8u43M8UwHMqZdL-S2gjho8j0-Fe1XuH5wYr9v'}

Please go to this quick example I've created jsFiddle. Hopefull it's easy to understand. You can use a wrapper div with the width of the site to center align. The reason you must put width is that so browser knows you are not going for a liquid layout.

To check if a Variant is Null, you need to do it like:

Isnull(myvar) = True

or

Not Isnull(myvar)

I had the same issue today. The file I was trying to load into my code was open for editing in Excel. After closing Excel, the code began to work!

I consider you can set the main content to viewport height, so if the content exceeds, the height of the main content will define the position of the footer

* {
  margin: 0;
  padding: 0;
  width: 100%;
}

body {
  display: flex;
  flex-direction: column;
}

header {
  height: 50px;
  background: red;
}

main {
  background: blue;
  /* This is the most important part*/
  height: 100vh; 
  
}
footer{
  background: black;
  height: 50px;
  bottom: 0;
}

<header></header>
<main></main>
<footer></footer>

If you want to due this in component.ts

HTML:

<button class="class1 class2" (click)="clicked($event)">Click me</button>

Component:

clicked(event) {
  event.target.classList.add('class3'); // To ADD
  event.target.classList.remove('class1'); // To Remove
  event.target.classList.contains('class2'); // To check
  event.target.classList.toggle('class4'); // To toggle
}

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

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

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

Both are not interchangable.

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

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

Sample request:

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

name=sam&age=35

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

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

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

Sample request:

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

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

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

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

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

sample response:

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

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

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

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

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

Sample request:

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

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

Above request is expecting XML from the server.

Regarding your question,

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

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

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

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

whereas

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

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

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

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

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

Now this answer is for those lost souls that got here with this problem because they force-unmounted the drive but their hard drive is NTFS Formatted. Assuming you have ntfs-3g installed (sudo apt-get install ntfs-3g).

sudo ntfs-3g /dev/hdd /mnt/mount_point -o force

Where hdd is the hard drive in question and the "/mnt/mount_point" directory exists.

NOTES: This fixed the issue on an Ubuntu 18.04 machine using NTFS drives that had their journal files reset through sudo ntfsfix /dev/hdd and unmounted by force using sudo umount -l /mnt/mount_point

Leaving my answer here in case this fix can aid anyone!

Floating Point Exception happens because of an unexpected infinity or NaN. You can track that using gdb, which allows you to see what is going on inside your C program while it runs. For more details: https://www.cs.swarthmore.edu/~newhall/unixhelp/howto_gdb.php

In a nutshell, these commands might be useful...

gcc -g myprog.c

gdb a.out

gdb core a.out

ddd a.out

Try this:

SELECT RawXML.value('(/GrobXmlFile//Grob//ReportHeader//OrganizationReportReferenceIdentifier/node())[1]','varchar(50)') AS ReportIdentifierNumber,
       RawXML.value('(/GrobXmlFile//Grob//ReportHeader//OrganizationNumber/node())[1]','int') AS OrginazationNumber
FROM Batches

IF your data won't overflow 4000 characters AND you're on SQL Server 2000 or compatibility level of 8 or SQL Server 2000:

UPDATE [CMS_DB_test].[dbo].[cms_HtmlText] 
SET Content = CAST(REPLACE(CAST(Content as NVarchar(4000)),'ABC','DEF') AS NText)
WHERE Content LIKE '%ABC%' 

For SQL Server 2005+:

UPDATE [CMS_DB_test].[dbo].[cms_HtmlText] 
SET Content = CAST(REPLACE(CAST(Content as NVarchar(MAX)),'ABC','DEF') AS NText)
WHERE Content LIKE '%ABC%' 

Below code is used to selected the first item and highlight the selected first item in the menu.

onNavigationItemSelected(mNavigationView.getMenu().getItem(0).setChecked(true));

Notice that if the file's parent folder doesn't exist you'll get the same error:

IOError: [Errno 2] No such file or directory:

Below is another solution which handles this case:
(*) I used sys.stdout and print instead of f.write just to show another use case

# Make sure the file's folder exist - Create folder if doesn't exist
folder_path = 'path/to/'+folder_name+'/'
if not os.path.exists(folder_path):
     os.makedirs(folder_path)

print_to_log_file(folder_path, "Some File" ,"Some Content")

Where the internal print_to_log_file just take care of the file level:

# If you're not familiar with sys.stdout - just ignore it below (just a use case example)
def print_to_log_file(folder_path ,file_name ,content_to_write):

   #1) Save a reference to the original standard output       
    original_stdout = sys.stdout   
    
    #2) Choose the mode
    write_append_mode = 'a' #Append mode
    file_path = folder_path + file_name
    if (if not os.path.exists(file_path) ):
       write_append_mode = 'w' # Write mode
     
    #3) Perform action on file
    with open(file_path, write_append_mode) as f:
        sys.stdout = f  # Change the standard output to the file we created.
        print(file_path, content_to_write)
        sys.stdout = original_stdout  # Reset the standard output to its original value

Consider the following states:

'w'  --> Write to existing file
'w+' --> Write to file, Create it if doesn't exist
'a'  --> Append to file
'a+' --> Append to file, Create it if doesn't exist

In your case I would use a different approach and just use 'a' and 'a+'.

Exclude all from subfolders works like this (version 2019)

include

./db

exclude

./db/*

If you want to ask based on condition:

var ask = true
window.onbeforeunload = function (e) {
    if(!ask) return null
    e = e || window.event;
    //old browsers
    if (e) {e.returnValue = 'Sure?';}
    //safari, chrome(chrome ignores text)
    return 'Sure?';
};

I rename in code

echo off

setlocal EnableDelayedExpansion

for %%a in (*.txt) do (
    REM echo %%a
    set x=%%a
    set mes=!x:~17,3!

    if !mes!==JAN (
        set mes=01
    )

    if !mes!==ENE (
        set mes=01
    )

    if !mes!==FEB (
        set mes=02
    )

    if !mes!==MAR (
        set mes=03
    )

    if !mes!==APR (
        set mes=04
    )

    if !mes!==MAY (
        set mes=05
    )

    if !mes!==JUN (
        set mes=06
    )

    if !mes!==JUL (
        set mes=07
    )

    if !mes!==AUG (
        set mes=08
    )

    if !mes!==SEP (
        set mes=09
    )

    if !mes!==OCT (
        set mes=10
    )

    if !mes!==NOV (
        set mes=11
    )

    if !mes!==DEC (
        set mes=12
    )

    ren %%a !x:~20,4!!mes!!x:~15,2!.txt 

    echo !x:~20,4!!mes!!x:~15,2!.txt 

)

While technically valid, all these jumps obscure control flow -- especially the continue statement.

I would use such a trick as a last resort, not first one.

How about

while (something = get_something())
{
    switch (something)
    {
    case A:
    case B:
        do_something();
    }        
}

It's shorter and perform its stuff in a more clear way.

Here's an elegant array formula (which I found here http://www.excel-easy.com/examples/count-unique-values.html) that does the trick nicely:

Type

=SUM(1/COUNTIF(List,List))

and confirm with CTRL-SHIFT-ENTER

a.mean() takes an axis argument:

In [1]: import numpy as np

In [2]: a = np.array([[40, 10], [50, 11]])

In [3]: a.mean(axis=1)     # to take the mean of each row
Out[3]: array([ 25. ,  30.5])

In [4]: a.mean(axis=0)     # to take the mean of each col
Out[4]: array([ 45. ,  10.5])

Or, as a standalone function:

In [5]: np.mean(a, axis=1)
Out[5]: array([ 25. ,  30.5])

The reason your slicing wasn't working is because this is the syntax for slicing:

In [6]: a[:,0].mean() # first column
Out[6]: 45.0

In [7]: a[:,1].mean() # second column
Out[7]: 10.5

I had a similar issue not long time ago and this was how I solved it

.rotated-half-circle {_x000D_
  /* Create the circle */_x000D_
  width: 40px;_x000D_
  height: 40px;_x000D_
  border: 10px solid black;_x000D_
  border-radius: 50%;_x000D_
  /* Halve the circle */_x000D_
  border-bottom-color: transparent;_x000D_
  border-left-color: transparent;_x000D_
  /* Rotate the circle */_x000D_
  transform: rotate(-45deg);_x000D_
}

<div class="rotated-half-circle"></div>

$("#myId").val() should work if myid is the select element id!

This would set the selected item: $("#myId").val('VALUE');

The second time you're referring to div2, you're not using the # id selector.

There's no element named div2.

there is also git stash - which "stashes" your local changes and can be reapplied at a later time or dropped if is no longer required

Select user id from list of user id:

SELECT * FROM my_table WHERE user_id IN (1,3,5,7,9,4);

If you can already see the SQL being printed, that means you have the code below in your hibernate.cfg.xml:

<property name="show_sql">true</property>

To print the bind parameters as well, add the following to your log4j.properties file:

log4j.logger.net.sf.hibernate.type=debug

If you are using python 2.7 or later, the easiest way to do this is to use the subprocess.check_output() command. Here is an example:

output = subprocess.check_output('ls')

To also redirect stderr you can use the following:

output = subprocess.check_output('ls', stderr=subprocess.STDOUT)

In the case that you want to pass parameters to the command, you can either use a list or use invoke a shell and use a single string.

output = subprocess.check_output(['ls', '-a'])
output = subprocess.check_output('ls -a', shell=True)

Lombok does not support that also indicated by making any @Value annotated class final (as you know by using @NonFinal).

The only workaround I found is to declare all members final yourself and use the @Data annotation instead. Those subclasses need to be annotated by @EqualsAndHashCode and need an explicit all args constructor as Lombok doesn't know how to create one using the all args one of the super class:

@Data
public class A {
    private final int x;
    private final int y;
}

@Data
@EqualsAndHashCode(callSuper = true)
public class B extends A {
    private final int z;

    public B(int x, int y, int z) {
        super(x, y);
        this.z = z;
    }
}

Especially the constructors of the subclasses make the solution a little untidy for superclasses with many members, sorry.

Couldn't you just call the following replaceing the {zipcode} with the zip code or city and state http://maps.googleapis.com/maps/api/geocode/json?address={zipcode}

Google Geocoding

Here is a link with a How To Geocode using JavaScript: Geocode walk-thru. If you need the specific lat/lng numbers call geometry.location.lat() or geometry.location.lng() (API for google.maps.LatLng class)

EXAMPLE to get lat/lng:

    var lat = '';
    var lng = '';
    var address = {zipcode} or {city and state};
    geocoder.geocode( { 'address': address}, function(results, status) {
      if (status == google.maps.GeocoderStatus.OK) {
         lat = results[0].geometry.location.lat();
         lng = results[0].geometry.location.lng();
        });
      } else {
        alert("Geocode was not successful for the following reason: " + status);
      }
    });
    alert('Latitude: ' + lat + ' Logitude: ' + lng);

A key compatibility issue is support for persistent connections. I recently worked on a server that "supported" HTTP/1.1, yet failed to close the connection when a client sent an HTTP/1.0 request. When writing a server that supports HTTP/1.1, be sure it also works well with HTTP/1.0-only clients.

System.out.println("Element "+i+list.get(0));}

Should be

System.out.println("Element "+i+list.get(i));}

To use the JSF tags, you give the dataList value attribute a reference to your list of elements, and the var attribute is a local name for each element of that list in turn. Inside the dataList, you use properties of the object (getters) to output the information about that individual object:

<t:dataList id="myDataList" value="#{houseControlList}" var="element" rows="3" >
...
<t:outputText id="houseId" value="#{element.houseId}"/>
...
</t:dataList>

It's Simple.You can use

select (sysdate+2) as new_date from dual;

This will add two days from current date.

to answer the first part of your question:

run

% mysqladmin -p -u <user-name> variables

and check the 'socket' variable

Answering my own question for documentation. I'm sure there are other ways to accomplish this, but this works and this code is tested.

<html>
<head>
<script language="Javascript" src="javascript/jquery-1.2.6.min.js"></script>
<script type="text/JavaScript">

$(function() {
    $(".update").bind("click",      // bind the click event to a div
        function() {
            var selectOption = $('.selDiv').children('.opts') ;
            var _this = $(this).next().children(".opts") ;

            $(selectOption).find("option[index='0']").attr("selected","selected");
//          $(selectOption).find("option[value='DEFAULT']").attr("selected","selected");
//          $(selectOption).find("option[text='Default']").attr("selected","selected");


//          $(_this).find("option[value='DEFAULT']").attr("selected","selected");
//          $(_this).find("option[text='Default']").attr("selected","selected");
//          $(_this).find("option[index='0']").attr("selected","selected");

    }); // END Bind
}); // End eventlistener

</script>
</head>
<body>
<div class="update" style="height:50px; color:blue; cursor:pointer;">Update</div>
<div class="selDiv">
        <select class="opts">
            <option selected value="DEFAULT">Default</option>
            <option value="SEL1">Selection 1</option>
            <option value="SEL2">Selection 2</option>
        </select>
    </div>
</body>

Both means "every item in a set of two things". The two things being "left" and "right"

You can fetch from a remote repo, see the differences and then pull or merge.

This is an example for a remote repo called origin and a branch called master tracking the remote branch origin/master:

git checkout master                                                  
git fetch                                        
git diff origin/master
git pull --rebase origin master

And has precedence over Or, so, even if a <=> a1 Or a2

Where a And b 

is not the same as

Where a1 Or a2 And b,

because that would be Executed as

Where a1 Or (a2 And b)

and what you want, to make them the same, is the following (using parentheses to override rules of precedence):

 Where (a1 Or a2) And b

Here's an example to illustrate:

Declare @x tinyInt = 1
Declare @y tinyInt = 0
Declare @z tinyInt = 0

Select Case When @x=1 OR @y=1 And @z=1 Then 'T' Else 'F' End -- outputs T
Select Case When (@x=1 OR @y=1) And @z=1 Then 'T' Else 'F' End -- outputs F

For those who like to consult references (in alphabetic order):

• Microsoft Transact-SQL operator precedence
• Oracle MySQL 9 operator precedence
• Oracle 10g condition precedence
• PostgreSQL operator Precedence
• SQL as understood by SQLite

Also the complexity of concatenations of String is O(N2), while for StringBuffer it is O(N).

So there might be performance problem where we use concatenations in loops as a lot of new objects are created each time.

Try this:

^[1-9]\d*$

...and some padding to exceed 30 character SO answer limit :-).

Here is Demo

Swift 4:

It depends by the encoding rules followed by your server.

Apple offer this class method, but it don't report wich kind of RCF protocol it follows.

var escapedString = originalString.addingPercentEncoding(withAllowedCharacters: .urlHostAllowed)!

Following this useful tool you should guarantee the encoding of these chars for your parameters:

• $ (Dollar Sign) becomes %24
• & (Ampersand) becomes %26
• + (Plus) becomes %2B
• , (Comma) becomes %2C
• : (Colon) becomes %3A
• ; (Semi-Colon) becomes %3B
• = (Equals) becomes %3D
• ? (Question Mark) becomes %3F
• @ (Commercial A / At) becomes %40

In other words, speaking about URL encoding, you should following the RFC 1738 protocol.

And Swift don't cover the encoding of the + char for example, but it works well with these three @ : ? chars.

So, to correctly encoding each your parameter , the .urlHostAllowed option is not enough, you should add also the special chars as for example:

encodedParameter = parameter.replacingOccurrences(of: "+", with: "%2B")

Hope this helps someone who become crazy to search these informations.

str(x)

It's all you need to remember for 99% of cases.

As of my knowledge it is impossible to alter/modify a table type.You can create the type with a different name and then drop the old type and modify it to the new name

Credits to jkrajes

As per msdn, it is like 'The user-defined table type definition cannot be modified after it is created'.

From the standard

7.5.2 Element identifiers: the id and class attributes

Attribute definitions

id = name [CS]
This attribute assigns a name to an element. This name must be unique in a document.

class = cdata-list [CS]
This attribute assigns a class name or set of class names to an element. Any number of elements may be assigned the same class name or names. Multiple class names must be separated by white space characters.

Yes, just put a space between them.

Of course, there are many things you can do with CSS inheritance. Here is an article for further reading.

Another alternative, even though the OP did not ask for it:

There exist usb-to-serial adapters. Depending on the type of adapter, you may also need a nullmodem cable, too.

They are extremely easy to use under linux, work under windows, too, if you have got working drivers installed.

That way you can work directly with the sensors, and you do not have to try and emulate data. That way you are maybe even save from building an anemic system. (Due to your emulated data inputs not covering all cases, leading you to a brittle system.)

Its often better to work with the real stuff.

datatable.rows().iterator('row', function ( context, index ) {
    var data = this.row(index).data();
    var row = $(this.row(index).node());
    data[0] = 'new data';
    datatable.row(row).data(data).draw();
});

If you want to find a specific user's home directory, I don't believe you can do it directly.

When I've needed to do this before from Java I had to write some JNI native code that wrapped the UNIX getpwXXX() family of calls.

All of these are returning equals. They arent actually doing a comparison, which is useful for sort. This will behave more like a comparator:

private static final Comparator stringFallbackComparator = new Comparator() {
    public int compare(Object o1, Object o2) {
        if (!(o1 instanceof Comparable))
            o1 = o1.toString();
        if (!(o2 instanceof Comparable))
            o2 = o2.toString();
        return ((Comparable)o1).compareTo(o2);
    }
};

public int compare(Map m1, Map m2) {
    TreeSet s1 = new TreeSet(stringFallbackComparator); s1.addAll(m1.keySet());
    TreeSet s2 = new TreeSet(stringFallbackComparator); s2.addAll(m2.keySet());
    Iterator i1 = s1.iterator();
    Iterator i2 = s2.iterator();
    int i;
    while (i1.hasNext() && i2.hasNext())
    {
        Object k1 = i1.next();
        Object k2 = i2.next();
        if (0!=(i=stringFallbackComparator.compare(k1, k2)))
            return i;
        if (0!=(i=stringFallbackComparator.compare(m1.get(k1), m2.get(k2))))
            return i;
    }
    if (i1.hasNext())
        return 1;
    if (i2.hasNext())
        return -1;
    return 0;
}

Another good approach not mentioned in other posts is to use PropertyOverrideConfigurer in case you just want to override properties of some beans.

For example if you want to override the datasource for testing (i.e. use an in-memory database) in another xml config, you just need to use <context:property-override ..."/> in new config and a .properties file containing key-values taking the format beanName.property=newvalue overriding the main props.

application-mainConfig.xml:

What about this:

function($arg = NULL) {

    if ($arg != NULL) {
        etc.
        etc.
    }
}

The listed return type of the method is Task<string>. You're trying to return a string. They are not the same, nor is there an implicit conversion from string to Task<string>, hence the error.

You're likely confusing this with an async method in which the return value is automatically wrapped in a Task by the compiler. Currently that method is not an async method. You almost certainly meant to do this:

private async Task<string> methodAsync() 
{
    await Task.Delay(10000);
    return "Hello";
}

There are two key changes. First, the method is marked as async, which means the return type is wrapped in a Task, making the method compile. Next, we don't want to do a blocking wait. As a general rule, when using the await model always avoid blocking waits when you can. Task.Delay is a task that will be completed after the specified number of milliseconds. By await-ing that task we are effectively performing a non-blocking wait for that time (in actuality the remainder of the method is a continuation of that task).

If you prefer a 4.0 way of doing it, without using await , you can do this:

private Task<string> methodAsync() 
{
    return Task.Delay(10000)
        .ContinueWith(t => "Hello");
}

The first version will compile down to something that is more or less like this, but it will have some extra boilerplate code in their for supporting error handling and other functionality of await we aren't leveraging here.

If your Thread.Sleep(10000) is really meant to just be a placeholder for some long running method, as opposed to just a way of waiting for a while, then you'll need to ensure that the work is done in another thread, instead of the current context. The easiest way of doing that is through Task.Run:

private Task<string> methodAsync() 
{
    return Task.Run(()=>
        {
            SomeLongRunningMethod();
            return "Hello";
        });
}

Or more likely:

private Task<string> methodAsync() 
{
    return Task.Run(()=>
        {
            return SomeLongRunningMethodThatReturnsAString();
        });
}

You can also use:

Get-WmiObject -Class "Win32_computersystem" | Select *

This will show the same result as Format-List * used in the other answers here.

For me, This error was because i had a prepare segue step that wasn't applicable to the segue that was being done.

long story:

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {

        let gosetup = segue.destination as! Update
        gosetup.wherefrom = updatestring

    }

This was being done to all segue when it was only for one. So i create a boolean and placed the gosetup inside it.

This is the complete way to omit unneeded redirects, too ;)

These rules are intended to be used in .htaccess files, as a RewriteRule in a *:80 VirtualHost entry needs no Conditions.

RewriteEngine on
RewriteCond %{HTTPS} off [OR] 
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule ^/(.*) https://%{HTTP_HOST}/$1 [NC,R=301,L]

Eplanations:

RewriteEngine on

==> enable the engine at all

RewriteCond %{HTTPS} off [OR]

==> match on non-https connections, or (not setting [OR] would cause an implicit AND !)

RewriteCond %{HTTP:X-Forwarded-Proto} !https

==> match on forwarded connections (proxy, loadbalancer, etc.) without https

RewriteRule ^/(.*) https://%{HTTP_HOST}/$1 [NC,R=301,L]

==> if one of both Conditions match, do the rewrite of the whole URL, sending a 301 to have this 'learned' by the client (some do, some don't) and the L for the last rule.

You are mixing the 1.5.6 version of the jcl bridge with the 1.6.0 version of the slf4j-api; this won't work because of a few changes in 1.6.0. Use the same versions for both, i.e. 1.6.1 (the latest). I use the jcl-over-slf4j bridge all the time and it works fine.

Simply put, abstraction is all about making necessary information for interaction with the object visible, while encapsulation enables a developer to implement the desired level of abstraction.

You can use MultiIndex.droplevel:

>>> cols = pd.MultiIndex.from_tuples([("a", "b"), ("a", "c")])
>>> df = pd.DataFrame([[1,2], [3,4]], columns=cols)
>>> df
   a   
   b  c
0  1  2
1  3  4

[2 rows x 2 columns]
>>> df.columns = df.columns.droplevel()
>>> df
   b  c
0  1  2
1  3  4

[2 rows x 2 columns]

Just put the labels in a div inside the TD and put the height and overflow.. like below.

  <td><div style="height:40px; overflow:hidden">Text</div></td>
  <td><div style="height:40px; overflow:hidden">Here</div></td>
</tr>
</table>

Is WebSockets over TCP a fast enough protocol to stream a video of, say, 30fps?

Yes.. it is, take a look at this project. Websockets can easily handle HD videostreaming.. However, you should go for Adaptive Streaming. I explain here how you could implement it.

Currently we're working on a webbased instant messaging application with chat, filesharing and video/webcam support. With some bits and tricks we got streaming media through websockets (used HTML5 Media Capture to get the stream from our webcams).

You need to build a stream API and a Media Stream Transceiver to control the related media processing and transport.

Reset the file in a correct state, commit, and push again.

If you're sure nobody else has fetched your changes yet, you can use --amend when committing, to modify your previous commit (i.e. rewrite history), and then push. I think you'll have to use the -f option when pushing, to force the push, though.

Depending upon your environment, you may want to add scripting to have .bashrc load automatically when you open an SSH session. I recently did a migration to a server running Ubuntu, and there, .profile, not .bashrc or .bash_profile is loaded by default. To run any scripts in .bashrc, I had to run source ~/.bashrc every time a session was opened, which doesn't help when running remote deploys.

To have your .bashrc load automatically when opening a session, try adding this to .profile:

if [ -n "$BASH_VERSION" ]; then
    # include .bashrc if it exists
    if [ -f "$HOME/.bashrc" ]; then
        . "$HOME/.bashrc"
    fi
fi

Reopen your session, and it should load any paths/scripts you have in .bashrc.

Using a for loop, how do I access the loop index, from 1 to 5 in this case?

Use enumerate to get the index with the element as you iterate:

for index, item in enumerate(items):
    print(index, item)

And note that Python's indexes start at zero, so you would get 0 to 4 with the above. If you want the count, 1 to 5, do this:

for count, item in enumerate(items, start=1):
    print(count, item)

Unidiomatic control flow

What you are asking for is the Pythonic equivalent of the following, which is the algorithm most programmers of lower-level languages would use:

index = 0            # Python's indexing starts at zero
for item in items:   # Python's for loops are a "for each" loop 
    print(index, item)
    index += 1

Or in languages that do not have a for-each loop:

index = 0
while index < len(items):
    print(index, items[index])
    index += 1

or sometimes more commonly (but unidiomatically) found in Python:

for index in range(len(items)):
    print(index, items[index])

Use the Enumerate Function

Python's enumerate function reduces the visual clutter by hiding the accounting for the indexes, and encapsulating the iterable into another iterable (an enumerate object) that yields a two-item tuple of the index and the item that the original iterable would provide. That looks like this:

for index, item in enumerate(items, start=0):   # default is zero
    print(index, item)

This code sample is fairly well the canonical example of the difference between code that is idiomatic of Python and code that is not. Idiomatic code is sophisticated (but not complicated) Python, written in the way that it was intended to be used. Idiomatic code is expected by the designers of the language, which means that usually this code is not just more readable, but also more efficient.

Getting a count

Even if you don't need indexes as you go, but you need a count of the iterations (sometimes desirable) you can start with 1 and the final number will be your count.

for count, item in enumerate(items, start=1):   # default is zero
    print(item)

print('there were {0} items printed'.format(count))

The count seems to be more what you intend to ask for (as opposed to index) when you said you wanted from 1 to 5.

Breaking it down - a step by step explanation

To break these examples down, say we have a list of items that we want to iterate over with an index:

items = ['a', 'b', 'c', 'd', 'e']

Now we pass this iterable to enumerate, creating an enumerate object:

enumerate_object = enumerate(items) # the enumerate object

We can pull the first item out of this iterable that we would get in a loop with the next function:

iteration = next(enumerate_object) # first iteration from enumerate
print(iteration)

And we see we get a tuple of 0, the first index, and 'a', the first item:

(0, 'a')

we can use what is referred to as "sequence unpacking" to extract the elements from this two-tuple:

index, item = iteration
#   0,  'a' = (0, 'a') # essentially this.

and when we inspect index, we find it refers to the first index, 0, and item refers to the first item, 'a'.

>>> print(index)
0
>>> print(item)
a

Conclusion

• Python indexes start at zero
• To get these indexes from an iterable as you iterate over it, use the enumerate function
• Using enumerate in the idiomatic way (along with tuple unpacking) creates code that is more readable and maintainable:

So do this:

for index, item in enumerate(items, start=0):   # Python indexes start at zero
    print(index, item)

I'm answering only the part of the question about zbar installation.

I spent nearly half an hour a few hours to make it work on Windows + Python 2.7 64-bit, so here are additional notes to the accepted answer:

• Download https://github.com/NaturalHistoryMuseum/ZBarWin64/releases/download/v0.10/zbar-0.10-cp27-none-win_amd64.whl

• Install it with pip install zbar-0.10-cp27-none-win_amd64.whl

• If Python reports an ImportError: DLL load failed: The specified module could not be found. when doing import zbar, then you will just need to install the Visual C++ Redistributable Packages for VS 2013 (I spent a lot of time here, trying to recompile unsuccessfully...)

• Required too: libzbar64-0.dll must be in a folder which is in the PATH. In my case I copied it to "C:\Python27\libzbar64-0.dll" (which is in the PATH). If it still does not work, add this:

  import os
  os.environ['PATH'] += ';C:\\Python27' 
  import zbar
  

PS: Making it work with Python 3.x is even more difficult: Compile zbar for Python 3.x.

PS2: I just tested pyzbar with pip install pyzbar and it's MUCH easier, it works out-of-the-box (the only thing is you need to have VC Redist 2013 files installed). It is also recommended to use this library in this pyimagesearch.com article.

You will need to check both parts of the path (directory and filename) and create each if it does not exist.

Use File.Exists and Directory.Exists to find out whether they exist. Directory.CreateDirectory will create the whole path for you, so you only ever need to call that once if the directory does not exist, then simply create the file.

This issue could be because of wrong entity framework reference or sometimes the Class name not matching the entity name in database. Make sure the Table name matches with class name.

Make your array a variable and use implode.

$array = array('lastname', 'email', 'phone');
$comma_separated = implode(",", $array);

echo $comma_separated; // lastname,email,phone

To convert the Keys to a List of their own:

listNumber = dicNumber.Select(kvp => kvp.Key).ToList();

Or you can shorten it up and not even bother using select:

listNumber = dicNumber.Keys.ToList();

I know this is an old question, but is the first google result for "sort observablecollection" so thought it worth to leave my two cent.

The way

The way I would go is to build a List<> starting from the ObservableCollection<>, sort it (through its Sort() method, more on msdn) and when the List<> has been sorted, reorder the ObservableCollection<> with the Move() method.

The code

public static void Sort<T>(this ObservableCollection<T> collection, Comparison<T> comparison)
{
    var sortableList = new List<T>(collection);
    sortableList.Sort(comparison);

    for (int i = 0; i < sortableList.Count; i++)
    {
        collection.Move(collection.IndexOf(sortableList[i]), i);
    }
}

The test

public void TestObservableCollectionSortExtension()
{
    var observableCollection = new ObservableCollection<int>();
    var maxValue = 10;

    // Populate the list in reverse mode [maxValue, maxValue-1, ..., 1, 0]
    for (int i = maxValue; i >= 0; i--)
    {
        observableCollection.Add(i);
    }

    // Assert the collection is in reverse mode
    for (int i = maxValue; i >= 0; i--)
    {
        Assert.AreEqual(i, observableCollection[maxValue - i]);
    }

    // Sort the observable collection
    observableCollection.Sort((a, b) => { return a.CompareTo(b); });

    // Assert elements have been sorted
    for (int i = 0; i < maxValue; i++)
    {
        Assert.AreEqual(i, observableCollection[i]);
    }
}

Notes

This is just a proof of concept, showing how to sort an ObservableCollection<> without breaking the bindings on items.The sort algorithm has room for improvements and validations (like index checking as pointed out here).

Necromancing.
It looks you have just as good a schema to work with as me... Here is how to do it correctly:

In this example, the table name is dbo.T_SYS_Language_Forms, and the column name is LANG_UID

-- First, chech if the table exists...
IF 0 < (
    SELECT COUNT(*) FROM INFORMATION_SCHEMA.TABLES 
    WHERE TABLE_TYPE = 'BASE TABLE'
    AND TABLE_SCHEMA = 'dbo'
    AND TABLE_NAME = 'T_SYS_Language_Forms'
)
BEGIN
    -- Check for NULL values in the primary-key column
    IF 0 = (SELECT COUNT(*) FROM T_SYS_Language_Forms WHERE LANG_UID IS NULL)
    BEGIN
        ALTER TABLE T_SYS_Language_Forms ALTER COLUMN LANG_UID uniqueidentifier NOT NULL 

        -- No, don't drop, FK references might already exist...
        -- Drop PK if exists 
        -- ALTER TABLE T_SYS_Language_Forms DROP CONSTRAINT pk_constraint_name 
        --DECLARE @pkDropCommand nvarchar(1000) 
        --SET @pkDropCommand = N'ALTER TABLE T_SYS_Language_Forms DROP CONSTRAINT ' + QUOTENAME((SELECT CONSTRAINT_NAME FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS 
        --WHERE CONSTRAINT_TYPE = 'PRIMARY KEY' 
        --AND TABLE_SCHEMA = 'dbo' 
        --AND TABLE_NAME = 'T_SYS_Language_Forms' 
        ----AND CONSTRAINT_NAME = 'PK_T_SYS_Language_Forms' 
        --))
        ---- PRINT @pkDropCommand 
        --EXECUTE(@pkDropCommand) 

        -- Instead do
        -- EXEC sp_rename 'dbo.T_SYS_Language_Forms.PK_T_SYS_Language_Forms1234565', 'PK_T_SYS_Language_Forms';


        -- Check if they keys are unique (it is very possible they might not be) 
        IF 1 >= (SELECT TOP 1 COUNT(*) AS cnt FROM T_SYS_Language_Forms GROUP BY LANG_UID ORDER BY cnt DESC)
        BEGIN

            -- If no Primary key for this table
            IF 0 =  
            (
                SELECT COUNT(*) FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS 
                WHERE CONSTRAINT_TYPE = 'PRIMARY KEY' 
                AND TABLE_SCHEMA = 'dbo' 
                AND TABLE_NAME = 'T_SYS_Language_Forms' 
                -- AND CONSTRAINT_NAME = 'PK_T_SYS_Language_Forms' 
            )
                ALTER TABLE T_SYS_Language_Forms ADD CONSTRAINT PK_T_SYS_Language_Forms PRIMARY KEY CLUSTERED (LANG_UID ASC)
            ;

            -- Adding foreign key
            IF 0 = (SELECT COUNT(*) FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS WHERE CONSTRAINT_NAME = 'FK_T_ZO_SYS_Language_Forms_T_SYS_Language_Forms') 
                ALTER TABLE T_ZO_SYS_Language_Forms WITH NOCHECK ADD CONSTRAINT FK_T_ZO_SYS_Language_Forms_T_SYS_Language_Forms FOREIGN KEY(ZOLANG_LANG_UID) REFERENCES T_SYS_Language_Forms(LANG_UID); 
        END -- End uniqueness check
        ELSE
            PRINT 'FSCK, this column has duplicate keys, and can thus not be changed to primary key...' 
    END -- End NULL check
    ELSE
        PRINT 'FSCK, need to figure out how to update NULL value(s)...' 
END
