Array#splice()
is the way to go, unless you really want to avoid mutating the array. Given 2 arrays arr1
and arr2
, here's how you would insert the contents of arr2
into arr1
after the first element:
const arr1 = ['a', 'd', 'e'];_x000D_
const arr2 = ['b', 'c'];_x000D_
_x000D_
arr1.splice(1, 0, ...arr2); // arr1 now contains ['a', 'b', 'c', 'd', 'e']_x000D_
_x000D_
console.log(arr1)
_x000D_
If you are concerned about mutating the array (for example, if using Immutable.js), you can instead use slice()
, not to be confused with splice()
with a 'p'
.
const arr3 = [...arr1.slice(0, 1), ...arr2, ...arr1.slice(1)];
Making it invisible with visibility still makes it use up space. Rather try set the display to none to make it invisible, and then set the display to block to make it visible.
Firstly, I don't think spaces for an id is valid.
So i'd change the id to not include spaces.
<label year="2010" month="6" id="currentMonth"> June 2010</label>
then the jquery code is simple (keep in mind, its better to fetch the jquery object once and use over and over agian)
var label = $('#currentMonth');
var month = label.attr('month');
var year = label.attr('year');
var text = label.text();
Using System Preferences:
Step 1: Click the Apple icon (at the top left of the screen) and select System Preferences.
Step 2: Click Network.
Step 3: Select your network connection and then click Advanced.
Step 4: Select the TCP/IP tab and find your gateway IP address listed next to Router.
I prefer going the long route. These are the checks I follow to avoid using a try-except clause -
Here, DATA
is the suspect variable -
DATA is not None and isinstance(DATA, pd.DataFrame) and not DATA.empty
In Addition to @Yifei answer. If you have special character like @, &, $
You have to go with percent-encode | encode the special characters. E.g. instead of this:
http://foo:B@[email protected]:80
you write this:
http://foo:B%[email protected]:80
So @
gets replaced with %40
.
Just /
refers to the root of your website from the public html folder. DOCUMENT_ROOT
refers to the local path to the folder on the server that contains your website.
For example, I have EasyPHP setup on a machine...
$_SERVER["DOCUMENT_ROOT"]
gives me file:///C:/Program%20Files%20(x86)/EasyPHP-5.3.9/www
but any file I link to with just /
will be relative to my www
folder.
If you want to give the absolute path to a file on your server (from the server's root) you can use DOCUMENT_ROOT
. if you want to give the absolute path to a file from your website's root, use just /
.
just install ojdbc-full, That contains the 12.1.0.1 release.
For this case you can also sort using LINQ:
week = week.OrderBy(w => DateTime.Parse(w.date)).ToList();
It depends on what you want to do and what type of data/information you are displaying. In general, tables are reserved for displaying tabular data.
An alternate for your situation would be to use css. A simple option would be to float your image and give it a margin:
<p>
<img style="float: left; margin: 5px;" ... />
Text goes here...
</p>
This would cause the text to wrap around the image. If you don't want the text to wrap around the image, put the text in a separate container:
<div>
<img style="float: left; margin: ...;" ... />
<p style="float: right;">Text goes here...</p>
</div>
Note that it may be necessary to assign a width to the paragraph tag to display the way you'd like. Also note, for elements that appear below floated elements, you may need to add the style "clear: left;" (or clear: right, or clear: both).
In my opinion many of the answers here seem a little bit hacky (e.g. $apply() or $timeout), since messing around with $apply() can lead to unwanted errors.
Usually, when the $location doesn't work it means that something was not implemented the angular way.
In this particular question, the problem seems to be in the non-angular AJAX part. I had a similiar problem, where the redirection using $location should take place after a promise resolved. I would like to illustrate the problem on this example.
The old code:
taskService.createTask(data).then(function(code){
$location.path("task/" + code);
}, function(error){});
Note: taskService.createTask returns a promise.
$q - the angular way to use promises:
let dataPromises = [taskService.createTask(data)];
$q.all(dataPromises).then(function(response) {
let code = response[0];
$location.path("task/" + code);
},
function(error){});
Using $q to resolve the promise solved the redirection problem.
More on the $q service: https://docs.angularjs.org/api/ng/service/$q
The solution is isblank(cell)=false
Just use in your if (key=="smk")
if (key=="smk") { window.open('http://www.smkproduction.eu5.org','_blank'); }
Good question.
True regular languages can not decide arbitrarily deeply nested well-formed parenthesis. If your alphabet contains '('
and ')'
the goal is to decide if a string of these has well-formed matching parenthesis. Since this is a necessary requirement for regular expressions the answer is no.
However, if you loosen the requirement and add recursion you can probably do it. The reason is that the recursion can act as a stack letting you "count" the current nesting depth by pushing onto this stack.
Russ Cox wrote "Regular Expression Matching Can Be Simple And Fast" which is a wonderful treatise on regex engine implementation.
In WSDL definition, bindings contain operations, here comes style for each operation.
Document : In WSDL file, it specifies types details either having inline Or imports XSD document, which describes the structure(i.e. schema) of the complex data types being exchanged by those service methods which makes loosely coupled. Document style is default.
In WSDL types element looks as follows:
<types>
<xsd:schema>
<xsd:import schemaLocation="http://localhost:9999/ws/hello?xsd=1" namespace="http://ws.peter.com/"/>
</xsd:schema>
</types>
The schema is importing from external reference.
RPC :In WSDL file, it does not creates types schema, within message elements it defines name and type attributes which makes tightly coupled.
<types/>
<message name="getHelloWorldAsString">
<part name="arg0" type="xsd:string"/>
</message>
<message name="getHelloWorldAsStringResponse">
<part name="return" type="xsd:string"/>
</message>
RPC : No types in WSDL
Document: Types section would be available in WSDL
Try nslookup google.com to determine if there's a DNS issue. 192.168.1.254 is your local network address and it looks like your system is using it as a DNS server. Is this your gateway/modem router as well? What happens when you try ping google.com. Can you browse to it on a Internet web browser?
Try this:
HTML
<select
ng-model="selectedOption"
ng-options="option.name for option in options">
</select>
Javascript
function Ctrl($scope) {
$scope.options = [
{
name: 'Something Cool',
value: 'something-cool-value'
},
{
name: 'Something Else',
value: 'something-else-value'
}
];
$scope.selectedOption = $scope.options[0];
}
Plunker here.
If you really want to set the value that will be bound to the model, then change the ng-options
attribute to
ng-options="option.value as option.name for option in options"
and the Javascript to
...
$scope.selectedOption = $scope.options[0].value;
Another Plunker here considering the above.
I don't think you should use the synchronous approach, asynchronously writing data to a file is better also stringify the output
if it's an object
.
Note: If output
is a string, then specify the encoding and remember the flag
options as well.:
const fs = require('fs');
const content = JSON.stringify(output);
fs.writeFile('/tmp/phraseFreqs.json', content, 'utf8', function (err) {
if (err) {
return console.log(err);
}
console.log("The file was saved!");
});
Added Synchronous method of writing data to a file, but please consider your use case. Asynchronous vs synchronous execution, what does it really mean?
const fs = require('fs');
const content = JSON.stringify(output);
fs.writeFileSync('/tmp/phraseFreqs.json', content);
getUserRootFolder() {
return process.env.HOME || process.env.HOMEPATH || process.env.USERPROFILE;
}
I've also found that if you had display:none, then programmatically changed it to be visible, you might also have to set
$tr.css({display:'table-row'});
rather than display:inline or display:block otherwise the cell might only show as taking up 1 cell, no matter how large you have the colspan set to.
I suggest
l = re.compile("(?<!^)\s+(?=[A-Z])(?!.\s)").split(s)
Check this demo.
I think I know why people would want this. "Run stuff if all conditions are true, otherwise run other stuff". And the conditions are too complicated to put into one if
.
Just use a lambda!
if (new Func<bool>(() =>
{
if (something1)
{
if (something2)
{
return true;
}
}
return false;
})())
{
//do stuff
}

and you may like to add:
// to remote the spacing between the image and button's borders
button.setMargin(new Insets(0, 0, 0, 0));
// to add a different background
button.setBackground( ... );
// to remove the border
button.setBorder(null);
Related answer, but if you want to run clean up a user inputting values into a form, here's what you can do:
const numFormatter = new Intl.NumberFormat('en-US', {
style: "decimal",
maximumFractionDigits: 2
})
// Good Inputs
parseFloat(numFormatter.format('1234').replace(/,/g,"")) // 1234
parseFloat(numFormatter.format('123').replace(/,/g,"")) // 123
// 3rd decimal place rounds to nearest
parseFloat(numFormatter.format('1234.233').replace(/,/g,"")); // 1234.23
parseFloat(numFormatter.format('1234.239').replace(/,/g,"")); // 1234.24
// Bad Inputs
parseFloat(numFormatter.format('1234.233a').replace(/,/g,"")); // NaN
parseFloat(numFormatter.format('$1234.23').replace(/,/g,"")); // NaN
// Edge Cases
parseFloat(numFormatter.format(true).replace(/,/g,"")) // 1
parseFloat(numFormatter.format(false).replace(/,/g,"")) // 0
parseFloat(numFormatter.format(NaN).replace(/,/g,"")) // NaN
Use the international date local via format
. This cleans up any bad inputs, if there is one it returns a string of NaN
you can check for. There's no way currently of removing commas as part of the locale (as of 10/12/19), so you can use a regex command to remove commas using replace
.
ParseFloat
converts the this type definition from string to number
If you use React, this is what your calculate function could look like:
updateCalculationInput = (e) => {
let value;
value = numFormatter.format(e.target.value); // 123,456.78 - 3rd decimal rounds to nearest number as expected
if(value === 'NaN') return; // locale returns string of NaN if fail
value = value.replace(/,/g, ""); // remove commas
value = parseFloat(value); // now parse to float should always be clean input
// Do the actual math and setState calls here
}
you can use AlertDialog
as ProgressDialog
refer below code for the ProgressDialog
. This function you need to call whenever you show a progress dialog.
Code:
public void setProgressDialog() {
int llPadding = 30;
LinearLayout ll = new LinearLayout(this);
ll.setOrientation(LinearLayout.HORIZONTAL);
ll.setPadding(llPadding, llPadding, llPadding, llPadding);
ll.setGravity(Gravity.CENTER);
LinearLayout.LayoutParams llParam = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
llParam.gravity = Gravity.CENTER;
ll.setLayoutParams(llParam);
ProgressBar progressBar = new ProgressBar(this);
progressBar.setIndeterminate(true);
progressBar.setPadding(0, 0, llPadding, 0);
progressBar.setLayoutParams(llParam);
llParam = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
llParam.gravity = Gravity.CENTER;
TextView tvText = new TextView(this);
tvText.setText("Loading ...");
tvText.setTextColor(Color.parseColor("#000000"));
tvText.setTextSize(20);
tvText.setLayoutParams(llParam);
ll.addView(progressBar);
ll.addView(tvText);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setCancelable(true);
builder.setView(ll);
AlertDialog dialog = builder.create();
dialog.show();
Window window = dialog.getWindow();
if (window != null) {
WindowManager.LayoutParams layoutParams = new WindowManager.LayoutParams();
layoutParams.copyFrom(dialog.getWindow().getAttributes());
layoutParams.width = LinearLayout.LayoutParams.WRAP_CONTENT;
layoutParams.height = LinearLayout.LayoutParams.WRAP_CONTENT;
dialog.getWindow().setAttributes(layoutParams);
}
}

Depends on how the switch in particular language works, however in most languages when no case is matched, the execution falls through the switch statement without warning. Imagine you expected some set of values and handled them in switch, however you get another value in the input. Nothing happens and you don't know nothing happened. If you caught the case in default, you would know there was something wrong.
If you want to split/cut the array on an index i,
arr = arr.drop(i)
> arr = [1,2,3,4,5]
=> [1, 2, 3, 4, 5]
> arr.drop(2)
=> [3, 4, 5]
I've created a way to do this with a better interface.

In Java, a long is a signed 64 bits number, which means you can store numbers between -9,223,372,036,854,775,808 and 9,223,372,036,854,775,807 (inclusive).
A int, on the other hand, is signed 32 bits number, which means you can store number between -2,147,483,648 and 2,147,483,647 (inclusive).
So if your long is outside of the values permitted for an int, you will not get a valuable conversion.

I agree with Ajeesh, but there are simpler ways to do this...
if ($maker == "2") { }
or
if ($maker == 2) { }
Why am I not returning a "Toyota" value? Because the "Toyota" choice in the Selection Box would have already returned "2", which, would indicate that the selected Manufacturer in the Selection Box would be Toyota.
How would the user know if the value is equal to the Toyota selection in the Selection Box? In between my example code's brackets, you would put $maker = "Toyota"
then echo $maker
, or create a new string, like so: $maketwo = "Toyota"
then you can echo $makertwo
(I much prefer creating a new string, rather than overwriting $maker
's original value.)
If the user selects "Nissan", will the example code take care of that as well..? Yes, and no. While "Toyota" would return value "2", "Nissan" would instead return value "3". The current set value that the example code is looking for is "2", which means that if the user selects "Nissan", which represents value "3", then presses "Search", the example code would not be executed. You can easily change the code to check for value "3", or value "1", which represents "--Any--".
What if the user clicks "Search" while the Selection Box is set to "Select Manufacturer"? How can I prevent them from doing so? To prevent them from proceeding any further, change the set value of the example code to "0", and in between the brackets, you may place your code, then after that, add return;
, which terminates all execution of any further code within the function / statement.
Due to security restrictions at my current place of work I was unable to set enviroment variables on my Windows based PC.
My workaround was to copy the mvn.bat file from %M2% into C:\WINNT and add the following to the top of the batch file:
@REM Needed as unable to set env variables on my desktop PC.
set MAVEN_OPTS=-Xms256m -Xmx1024m
set M2_HOME=C:\apache-maven-3.0.4
set M2=%M2_HOME%\bin
set JAVA_HOME=C:\Program Files\Java\jdk1.5.0_15
set PATH=%JAVA_HOME%\bin;%M2%;%PATH%
Not the nicest solution but it works. If anybody has any other way or work-around where the standard env vars are not able to be set into the system I'd welcome their response.

I would suggest looking at how browsers handle forms by default. For example take a look at the form element <select multiple>
and how it handles multiple values from this example at w3schools.
<form action="/action_page.php">
<select name="cars" multiple>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="opel">Opel</option>
<option value="audi">Audi</option>
</select>
<input type="submit">
</form>
For PHP use:
<select name="cars[]" multiple>
Live example from above at w3schools.com
From above if you click "saab, opel" and click submit, it will generate a result of cars=saab&cars=opel. Then depending on the back-end server, the parameter cars should come across as an array that you can further process.
Hope this helps anyone looking for a more 'standard' way of handling this issue.
This is a common problem . when we start the ftp connection only the external ip opens the port for pasv connection. but the ip behind the NAT doesn't open the connection so passive connection fails with PASV command
we need to specify that while opening the connection so open connection with
ftp -p {host}
FileNotFound in this case means you got a 404 from your server - could it be that the server does not like "POST" requests?
your code will look something like this ...
<!doctype html>
<html lang="en">
<head>
<style>
#button1{
width: 300px;
height: 40px;
}
#button2{
width: 300px;
height: 40px;
}
display:inline-block;
</style>
<meta charset="utf-8">
<meta name="Homepage" content="Starting page for the survey website ">
<title> Survey HomePage</title>
</head>
<body>
<center>
<img src="kingstonunilogo.jpg" alt="uni logo" style="width:180px;height:160px">
<button type="button home-button" id="button1" >Home</button>
<button type="button contact-button" id="button2">Contact Us</button>
</center>
</body>
</html>
It is important to highlight that the Property (MaximumErrorCount) that needs to be changed must be set as more than 0 (which is the default) in the Package level and not in the specific control that is showing the error (I tried this and it does not work!)
Be sure that in the Properties Window, the Pull down menu is set to "Package", then look for the property MaximumErrorCount to change it.
Try this one
.responsive-container{
display:table;
}
.img-container{
display:table-cell;
vertical-align: middle;
}
The problem has been explained previously so I will only reiterate: width doesn't take into account border and padding. One possible answer to this not discussed but which I have found helped me out a bunch is to wrap your inputs. Here's the code, and I'll explain how this helps in a second:
<table>
<tr>
<td><div style="overflow:hidden"><input style="width:100%" type="text" name="name" value="hello world" /></div></td>
</tr>
</table>
The DIV wrapping the INPUT has no padding nor does it have a border. This is the solution. A DIV will expand to its container's size, but it will also respect border and padding. Now, the INPUT will have no issue expanding to the size of its container since it is border-less and pad-less. Also note that the DIV has its overflow set to hidden. It seems that by default items can fall outside of their container with the default overflow of visible. This just ensures that the input stays inside its container and doesn't attempt to poke through.
I've tested this in Chrome and in Fire Fox. Both seem to respect this solution well.
UPDATE: Since I just got a random downvote, I would like to say that a better way to deal with overflow is with the CSS3 box-sizing attribute as described by pricco:
.myinput {
-moz-box-sizing: border-box;
-webkit-box-sizing: border-box;
-ms-box-sizing: border-box;
-o-box-sizing: border-box;
box-sizing: border-box;
}
This seems to be pretty well supported by the major browsers and isn't "hacky" like the overflow trick. There are, however, some minor issues on current browsers with this approach (see http://caniuse.com/#search=box-sizing Known Issues).
There are three simple ways:
By separator:
s.split("separator") | s.split('/') | s.split(char::is_numeric)
By whitespace:
s.split_whitespace()
By newlines:
s.lines()
By regex: (using regex
crate)
Regex::new(r"\s").unwrap().split("one two three")
The result of each kind is an iterator:
let text = "foo\r\nbar\n\nbaz\n";
let mut lines = text.lines();
assert_eq!(Some("foo"), lines.next());
assert_eq!(Some("bar"), lines.next());
assert_eq!(Some(""), lines.next());
assert_eq!(Some("baz"), lines.next());
assert_eq!(None, lines.next());
You can make use of the Support Library's NestedScrollView
and it's NestedScrollView.OnScrollChangeListener
interface.
https://developer.android.com/reference/android/support/v4/widget/NestedScrollView.html
Alternatively if your app is targeting API 23 or above, you can make use of the following method on the ScrollView
:
View.setOnScrollChangeListener(OnScrollChangeListener listener)
Then follow the example that @Fustigador described in his answer. Note however that as @Will described, you should consider adding a small buffer in case the user or system isn't able to reach the complete bottom of the list for any reason.
Also worth noting is that the scroll change listener will sometimes be called with negative values or values greater than the view height. Presumably these values represent the 'momentum' of the scroll action. However unless handled appropriately (floor / abs) they can cause problems detecting the scroll direction when the view is scrolled to the top or bottom of the range.
This post will go through the following topics:
merge
, join
, concat
There are a few options, some simpler than others depending on the use case.
DataFrame.merge
withleft_index
andright_index
(orleft_on
andright_on
using names indexes)
- supports inner/left/right/full
- can only join two at a time
- supports column-column, index-column, index-index joins
DataFrame.join
(join on index)
- supports inner/left (default)/right/full
- can join multiple DataFrames at a time
- supports index-index joins
pd.concat
(joins on index)
- supports inner/full (default)
- can join multiple DataFrames at a time
- supports index-index joins
Setup & Basics
import pandas as pd
import numpy as np
np.random.seed([3, 14])
left = pd.DataFrame(data={'value': np.random.randn(4)},
index=['A', 'B', 'C', 'D'])
right = pd.DataFrame(data={'value': np.random.randn(4)},
index=['B', 'D', 'E', 'F'])
left.index.name = right.index.name = 'idxkey'
left
value
idxkey
A -0.602923
B -0.402655
C 0.302329
D -0.524349
right
value
idxkey
B 0.543843
D 0.013135
E -0.326498
F 1.385076
Typically, an inner join on index would look like this:
left.merge(right, left_index=True, right_index=True)
value_x value_y
idxkey
B -0.402655 0.543843
D -0.524349 0.013135
Other joins follow similar syntax.
Notable Alternatives
DataFrame.join
defaults to joins on the index. DataFrame.join
does a LEFT OUTER JOIN by default, so how='inner'
is necessary here.
left.join(right, how='inner', lsuffix='_x', rsuffix='_y')
value_x value_y
idxkey
B -0.402655 0.543843
D -0.524349 0.013135
Note that I needed to specify the lsuffix
and rsuffix
arguments since join
would otherwise error out:
left.join(right)
ValueError: columns overlap but no suffix specified: Index(['value'], dtype='object')
Since the column names are the same. This would not be a problem if they were differently named.
left.rename(columns={'value':'leftvalue'}).join(right, how='inner')
leftvalue value
idxkey
B -0.402655 0.543843
D -0.524349 0.013135
pd.concat
joins on the index and can join two or more DataFrames at once. It does a full outer join by default, so how='inner'
is required here..
pd.concat([left, right], axis=1, sort=False, join='inner')
value value
idxkey
B -0.402655 0.543843
D -0.524349 0.013135
For more information on concat
, see this post.
To perform an inner join using index of left, column of right, you will use DataFrame.merge
a combination of left_index=True
and right_on=...
.
right2 = right.reset_index().rename({'idxkey' : 'colkey'}, axis=1)
right2
colkey value
0 B 0.543843
1 D 0.013135
2 E -0.326498
3 F 1.385076
left.merge(right2, left_index=True, right_on='colkey')
value_x colkey value_y
0 -0.402655 B 0.543843
1 -0.524349 D 0.013135
Other joins follow a similar structure. Note that only merge
can perform index to column joins. You can join on multiple columns, provided the number of index levels on the left equals the number of columns on the right.
join
and concat
are not capable of mixed merges. You will need to set the index as a pre-step using DataFrame.set_index
.
If your index is named, then from pandas >= 0.23, DataFrame.merge
allows you to specify the index name to on
(or left_on
and right_on
as necessary).
left.merge(right, on='idxkey')
value_x value_y
idxkey
B -0.402655 0.543843
D -0.524349 0.013135
For the previous example of merging with the index of left, column of right, you can use left_on
with the index name of left:
left.merge(right2, left_on='idxkey', right_on='colkey')
value_x colkey value_y
0 -0.402655 B 0.543843
1 -0.524349 D 0.013135

I drop a lot of same-sized same-dp screens, ignore height/width swap and include some sorting results.
$('#configreset').click(function(){
$('#configform')[0].reset();
});
Put it in JS fiddle. Worked as intended.
So, none of the aforementioned issues are at fault here. Maybe you're having a conflicting ID issue? Is the click actually executing?
Edit: (because I'm a sad sack without proper commenting ability) It's not an issue directly with your code. It works fine when you take it out of the context of the page that you're currently using, so, instead of it being something with the particular jQuery/javascript & attributed form data, it has to be something else. I'd start bisecting the code around it out and try to find where it's going on. I mean, just to 'make sure', i suppose you could...
console.log($('#configform')[0]);
in the click function and make sure it's targeting the right form...
and if it is, it has to be something that's not listed here.
edit part 2: One thing you could try (if it's not targeting it correctly) is use "input:reset" instead of what you are using... also, i'd suggest because it's not the target that's incorrectly working to find out what the actual click is targeting. Just open up firebug/developer tools, whathave you, toss in
console.log($('#configreset'))
and see what pops up. and then we can go from there.
Maybe this is not the answer you needed, but I encountered similar problem, so I decided to put it here.
I needed to convert 500 xml files to UTF8 via Notepad++. Why Notepad++? When I used the option "Encode in UTF8" (many other converters use the same logic) it messed up all special characters, so I had to use "Convert to UTF8" explicitly.
Here some simple steps to convert multiple files via Notepad++ without messing up with special characters (for ex. diacritical marks).
convertToUTF8.py
import os
import sys
from Npp import notepad # import it first!
filePathSrc="C:\\Users\\" # Path to the folder with files to convert
for root, dirs, files in os.walk(filePathSrc):
for fn in files:
if fn[-4:] == '.xml': # Specify type of the files
notepad.open(root + "\\" + fn)
notepad.runMenuCommand("Encoding", "Convert to UTF-8")
# notepad.save()
# if you try to save/replace the file, an annoying confirmation window would popup.
notepad.saveAs("{}{}".format(fn[:-4], '_utf8.xml'))
notepad.close()
After all, run the script
You could use OrderedDict (requires Python 2.7) or higher.
Also, note that OrderedDict({'a': 1, 'b':2, 'c':3})
won't work since the dict
you create with {...}
has already forgotten the order of the elements. Instead, you want to use OrderedDict([('a', 1), ('b', 2), ('c', 3)])
.
As mentioned in the documentation, for versions lower than Python 2.7, you can use this recipe.
In the W3 wiki page about structuring HTML5, it says:
<section>
: Used to either group different articles into different purposes or subjects, or to define the different sections of a single article.
And then displays an image that I cleaned up:
It also describes how to use the <article>
tag (from same W3 link above):
<article>
is related to<section>
, but is distinctly different. Whereas<section>
is for grouping distinct sections of content or functionality,<article>
is for containing related individual standalone pieces of content, such as individual blog posts, videos, images or news items. Think of it this way - if you have a number of items of content, each of which would be suitable for reading on their own, and would make sense to syndicate as separate items in an RSS feed, then<article>
is suitable for marking them up.In our example,
<section id="main">
contains blog entries. Each blog entry would be suitable for syndicating as an item in an RSS feed, and would make sense when read on its own, out of context, therefore<article>
is perfect for them:
<section id="main">
<article>
<!-- first blog post -->
</article>
<article>
<!-- second blog post -->
</article>
<article>
<!-- third blog post -->
</article>
</section>
Simple huh? Be aware though that you can also nest sections inside articles, where it makes sense to do so. For example, if each one of these blog posts has a consistent structure of distinct sections, then you could put sections inside your articles as well. It could look something like this:
<article>
<section id="introduction">
</section>
<section id="content">
</section>
<section id="summary">
</section>
</article>
First you have to call the function as they told you or the founction will display nothing in the output, after that save the file and copy the path of the file by right click to the folder of the file and click on"copy file" then go to terminal and write: - cd "the path of the file" - python "name of the file for example (main.py)" after that it will display the output of your code.
If the data is populated from the database, you might consider not using an <input>
tag to display it. Nevertheless, you can disable it right in the tag:
<input type='text' value='${magic.database.value}' disabled>
If you need to disable it with Javascript later, you can set the "disabled" attribute:
document.getElementById('theInput').disabled = true;
The reason I suggest not showing the value as an <input>
is that, in my experience, it causes layout issues. If the text is long, then in an <input>
the user will need to try and scroll the text, which is not something normal people would guess to do. If you just drop it into a <span>
or something, you have more styling flexibility.

I think you're mixed up between PATH and PYTHONPATH. All you have to do to run a 'script' is have it's parental directory appended to your PATH variable. You can test this by running
which myscript.py
Also, if myscripy.py
depends on custom modules, their parental directories must also be added to the PYTHONPATH variable. Unfortunately, because the designers of python were clearly on drugs, testing your imports in the repl with the following will not guarantee that your PYTHONPATH is set properly for use in a script. This part of python programming is magic and can't be answered appropriately on stackoverflow.

I'm going to provide a functional (immutable) way of doing it.
The standard and easy way of doing it is to use slicing:
index_to_remove = 3
data = [*range(5)]
new_data = data[:index_to_remove] + data[index_to_remove + 1:]
print(f"data: {data}, new_data: {new_data}")
Output:
data: [0, 1, 2, 3, 4], new_data: [0, 1, 2, 4]
Use list comprehension:
data = [*range(5)]
new_data = [v for i, v in enumerate(data) if i != index_to_remove]
print(f"data: {data}, new_data: {new_data}")
Output:
data: [0, 1, 2, 3, 4], new_data: [0, 1, 2, 4]
Use filter function:
index_to_remove = 3
data = [*range(5)]
new_data = [*filter(lambda i: i != index_to_remove, data)]
Output:
data: [0, 1, 2, 3, 4], new_data: [0, 1, 2, 4]
Using masking. Masking is provided by itertools.compress function in the standard library:
from itertools import compress
index_to_remove = 3
data = [*range(5)]
mask = [1] * len(data)
mask[index_to_remove] = 0
new_data = [*compress(data, mask)]
print(f"data: {data}, mask: {mask}, new_data: {new_data}")
Output:
data: [0, 1, 2, 3, 4], mask: [1, 1, 1, 0, 1], new_data: [0, 1, 2, 4]
Use itertools.filterfalse function from Python standard library
from itertools import filterfalse
index_to_remove = 3
data = [*range(5)]
new_data = [*filterfalse(lambda i: i == index_to_remove, data)]
print(f"data: {data}, new_data: {new_data}")
Output:
data: [0, 1, 2, 3, 4], new_data: [0, 1, 2, 4]
you could try this, works on ubuntu and mac
sudo chown -R $(whoami) /usr/local/lib/node_modules
Integer.parseInt(hex,16);
System.out.print(Integer.toBinaryString(hex));
Parse hex(String) to integer with base 16 then convert it to Binary String using toBinaryString(int) method
example
int num = (Integer.parseInt("A2B", 16));
System.out.print(Integer.toBinaryString(num));
Will Print
101000101011
Max Hex vakue Handled by int is FFFFFFF
i.e. if FFFFFFF0 is passed ti will give error
The solution I have found is to use $parse.
"Converts Angular expression into a function."
If anyone has a better one please add a new answer to the question!
Here is the example:
var the_string = 'life.meaning';
// Get the model
var model = $parse(the_string);
// Assigns a value to it
model.assign($scope, 42);
// Apply it to the scope
// $scope.$apply(); <- According to comments, this is no longer needed
console.log($scope.life.meaning); // logs 42
You can't use a variable in an IN
clause - you need to use dynamic SQL, or use a function (TSQL or CLR) to convert the list of values into a table.
Dynamic SQL example:
DECLARE @ExcludedList VARCHAR(MAX)
SET @ExcludedList = 3 + ',' + 4 + ',' + '22'
DECLARE @SQL NVARCHAR(4000)
SET @SQL = 'SELECT * FROM A WHERE Id NOT IN (@ExcludedList) '
BEGIN
EXEC sp_executesql @SQL '@ExcludedList VARCHAR(MAX)' @ExcludedList
END
The addNode
function needs to be able to change head
. As it's written now simply changes the local variable head
(a parameter).
Changing the code to
void addNode(struct Node *& head, int n){
...
}
would solve this problem because now the head
parameter is passed by reference and the called function can mutate it.
Try
it's basically raising the swap memory
sudo /bin/dd if=/dev/zero of=/var/swap.1 bs=1M count=1024 && sudo /sbin/mkswap /var/swap.1 && sudo /sbin/swapon /var/swap.1
Does the column allow null?
Seems to work. Just tested with phpMyAdmin, the column is of type int that allows nulls:
INSERT INTO `database`.`table` (`column`) VALUES (NULL);
I have a windows 7 and installing the ClickOnce Tools was not enough.
The signtool.exe
appeared after also installing the sdk:
I think your port is probably open, but you don't have anything that listens on it.
The Apple Mac OS X operating system has SSH installed by default but the SSH daemon is not enabled. This means you can’t login remotely or do remote copies until you enable it.
To enable it, go to ‘System Preferences’. Under ‘Internet & Networking’ there is a ‘Sharing’ icon. Run that. In the list that appears, check the ‘Remote Login’ option. In OS X Yosemite and up, there is no longer an 'Internet & Networking' menu; it was moved to Accounts. The Sharing menu now has its own icon on the main System Preferences menu. (thx @AstroCB)
This starts the SSH daemon immediately and you can remotely login using your username. The ‘Sharing’ window shows at the bottom the name and IP address to use. You can also find this out using ‘whoami’ and ‘ifconfig’ from the Terminal application.
These instructions are copied from Enable SSH in Mac OS X, but I wanted to make sure they won't go away and to provide quick access.
With the data.table package you could use the set()
function and loop over the columns and replace the NA
s or whatever you like with an aggregate or value of your choice (here: mean):
require(data.table)
# data
dt = copy(iris[ ,-5])
setDT(dt)
dt[1:4, Sepal.Length := NA] # introduce NAs
# replace NAs with mean (or whatever function you like)
for (j in seq_along(names(dt))) {
set(dt,
i = which(is.na(dt[[j]])),
j = j,
value = mean(dt[[j]], na.rm = TRUE))
}
I can't find a scenario that cannot be solved using node-fibers. The example you provided using node-fibers behaves as expected. The key is to run all the relevant code inside a fiber, so you don't have to start a new fiber in random positions.
Lets see an example: Say you use some framework, which is the entry point of your application (you cannot modify this framework). This framework loads nodejs modules as plugins, and calls some methods on the plugins. Lets say this framework only accepts synchronous functions, and does not use fibers by itself.
There is a library that you want to use in one of your plugins, but this library is async, and you don't want to modify it either.
The main thread cannot be yielded when no fiber is running, but you still can create plugins using fibers! Just create a wrapper entry that starts the whole framework inside a fiber, so you can yield the execution from the plugins.
Downside: If the framework uses setTimeout
or Promise
s internally, then it will escape the fiber context. This can be worked around by mocking setTimeout
, Promise.then
, and all event handlers.
So this is how you can yield a fiber until a Promise
is resolved. This code takes an async (Promise returning) function and resumes the fiber when the promise is resolved:
framework-entry.js
console.log(require("./my-plugin").run());
async-lib.js
exports.getValueAsync = () => {
return new Promise(resolve => {
setTimeout(() => {
resolve("Async Value");
}, 100);
});
};
my-plugin.js
const Fiber = require("fibers");
function fiberWaitFor(promiseOrValue) {
var fiber = Fiber.current, error, value;
Promise.resolve(promiseOrValue).then(v => {
error = false;
value = v;
fiber.run();
}, e => {
error = true;
value = e;
fiber.run();
});
Fiber.yield();
if (error) {
throw value;
} else {
return value;
}
}
const asyncLib = require("./async-lib");
exports.run = () => {
return fiberWaitFor(asyncLib.getValueAsync());
};
my-entry.js
require("fibers")(() => {
require("./framework-entry");
}).run();
When you run node framework-entry.js
it will throw an error: Error: yield() called with no fiber running
. If you run node my-entry.js
it works as expected.
Ajedi32's answer is what I was looking for but for some commits I ran into this error:
error: cannot apply binary patch to 'path/to/directory' without full index line
May be because some files of the directory are binary files. Adding '--binary' option to the git diff command fixed it:
git diff --binary --cached commit -- path/to/directory | git apply -R --index
You need to delegate event to the document level
$(document).on('submit','form.remember',function(){
// code
});
$('form.remember').on('submit'
work same as $('form.remember').submit(
but when you use $(document).on('submit','form.remember'
then it will also work for the DOM added later.
There is a very simple and easy solution to your question:

}

You don't. The whole reason for using the SecureString object is to avoid creating a string object (which is loaded into memory and kept there in plaintext until garbage collection). However, you can add characters to a SecureString by appending them.
var s = new SecureString();
s.AppendChar('d');
s.AppendChar('u');
s.AppendChar('m');
s.AppendChar('b');
s.AppendChar('p');
s.AppendChar('a');
s.AppendChar('s');
s.AppendChar('s');
s.AppendChar('w');
s.AppendChar('d');
There are many questions about REST auth patterns here on SO. These are the most relevant for your question:
Basically you need to choose between using API keys (least secure as the key may be discovered by an unauthorized user), an app key and token combo (medium), or a full OAuth implementation (most secure).
If you really want them to have ALL rights:
use YourDatabase
go
exec sp_addrolemember 'db_owner', 'UserName'
go
You might want to look into this C# function to escape the string:
http://www.aspcode.net/C-encode-a-string-for-JSON-JavaScript.aspx
public static string Enquote(string s)
{
if (s == null || s.Length == 0)
{
return "\"\"";
}
char c;
int i;
int len = s.Length;
StringBuilder sb = new StringBuilder(len + 4);
string t;
sb.Append('"');
for (i = 0; i < len; i += 1)
{
c = s[i];
if ((c == '\\') || (c == '"') || (c == '>'))
{
sb.Append('\\');
sb.Append(c);
}
else if (c == '\b')
sb.Append("\\b");
else if (c == '\t')
sb.Append("\\t");
else if (c == '\n')
sb.Append("\\n");
else if (c == '\f')
sb.Append("\\f");
else if (c == '\r')
sb.Append("\\r");
else
{
if (c < ' ')
{
//t = "000" + Integer.toHexString(c);
string t = new string(c,1);
t = "000" + int.Parse(tmp,System.Globalization.NumberStyles.HexNumber);
sb.Append("\\u" + t.Substring(t.Length - 4));
}
else
{
sb.Append(c);
}
}
}
sb.Append('"');
return sb.ToString();
}
also very comprehensive...

$.getJSON
is an asynchronous request, meaning the code will continue to run even though the request is not yet done. You should trigger the second request when the first one is done, one of the choices you seen already in ComFreek's answer.
Alternatively you could use jQuery's $.when/.then(), similar to this:
var input = "netuetamundis"; var sID; $(document).ready(function () { $.when($.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/" + input + "?api_key=API_KEY_HERE", function () { obj = name; sID = obj.id; console.log(sID); })).then(function () { $.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.2/stats/by-summoner/" + sID + "/summary?api_key=API_KEY_HERE", function (stats) { console.log(stats); }); }); });
This would be more open for future modification and separates out the responsibility for the first call to know about the second call.
The first call can simply complete and do it's own thing not having to be aware of any other logic you may want to add, leaving the coupling of the logic separated.
The following can be used to remove only multi blank lines (reduce them to a single blank line) and leaving single blank lines intact:

Built-in Helpers
#if
You can use the if helper to conditionally render a block. If its argument returns false, undefined, null, "", 0, or [], Handlebars will not render the block.
template
<div class="entry">
{{#if author}}
<h1>{{firstName}} {{lastName}}</h1>
{{else}}
<h1>Unknown Author</h1>
{{/if}}
</div>
When you pass the following input to the above template
{
author: true,
firstName: "Yehuda",
lastName: "Katz"
}
You can do this using generic SQL with group by
:
SELECT C.Content_ID, C.Content_Title, MAX(M.Media_Id)
FROM tbl_Contents C LEFT JOIN
tbl_Media M
ON M.Content_Id = C.Content_Id
GROUP BY C.Content_ID, C.Content_Title
ORDER BY MAX(C.Content_DatePublished) ASC;
Or with a correlated subquery:
SELECT C.Content_ID, C.Contt_Title,
(SELECT M.Media_Id
FROM tbl_Media M
WHERE M.Content_Id = C.Content_Id
ORDER BY M.MEDIA_ID DESC
LIMIT 1
) as Media_Id
FROM tbl_Contents C
ORDER BY C.Content_DatePublished ASC;
Of course, the syntax for limit 1
varies between databases. Could be top
. Or rownum = 1
. Or fetch first 1 rows
. Or something like that.
Another way to understand the relationship between these concepts is to interpret a ROLE as a container of Authorities.
Authorities are fine-grained permissions targeting a specific action coupled sometimes with specific data scope or context. For instance, Read, Write, Manage, can represent various levels of permissions to a given scope of information.
Also, authorities are enforced deep in the processing flow of a request while ROLE are filtered by request filter way before reaching the Controller. Best practices prescribe implementing the authorities enforcement past the Controller in the business layer.
On the other hand, ROLES are coarse grained representation of an set of permissions. A ROLE_READER would only have Read or View authority while a ROLE_EDITOR would have both Read and Write. Roles are mainly used for a first screening at the outskirt of the request processing such as http. ... .antMatcher(...).hasRole(ROLE_MANAGER)
The Authorities being enforced deep in the request's process flow allows a finer grained application of the permission. For instance, a user may have Read Write permission to first level a resource but only Read to a sub-resource. Having a ROLE_READER would restrain his right to edit the first level resource as he needs the Write permission to edit this resource but a @PreAuthorize interceptor could block his tentative to edit the sub-resource.

I think its possible provided if it is a serial data in broadcasting method. but you will not be able to transfer any voice/audio data to the other slave device. As per Bluetooth 4.0, the protocol does not support this. However there is a improvement going on to broadcast the audio/voice data.

You are trying to execute the number in the ENDTIME
as a command. You should also see an error like 1370306857: command not found
. Instead use the arithmetic expansion:
echo "It takes $(($ENDTIME - $STARTTIME)) seconds to complete this task..."
You could also save the commands in a separate script, commands.sh
, and use time command:
time commands.sh
An other solution rm(list=ls(pattern="temp"))
, remove all objects matching the pattern.
You can also try WANem which is an open source Wide Area Network emulator. You can download the image (ISO, Knoppix live CD) or VMWare virtual appliances.
npm install node-sass
will do the job in most of the cases, as it will add missing sass npm dependency module doesn't exist or it will overwrite previous crashed version.
For Mac Users use sudo
in front of above commands.
On Windows machines npm rebuild node-sass --force
may not work for some users because it's essentially saying, "please force npm to rebuild the sass node module for me". It will not work because that module doesn't exist.
Whenever you did npm install
to the initial installation, the sass module did not get installed, which is why this problem occurs.

(df.groupby(['col5', 'col2']).size()
.sort_values(ascending=False)
.reset_index(name='count')
.drop_duplicates(subset='col2'))
col5 col2 count
0 3 A 3
1 1 D 3
2 5 B 2
6 3 C 1
Explanation
The result of the groupby size
method is a Series with col5
and col2
in the index. From here, you can use another groupby method to find the maximum value of each value in col2
but it is not necessary to do. You can simply sort all the values descendingly and then keep only the rows with the first occurrence of col2
with the drop_duplicates
method.

Suppose you have a thread running which accepts client connections. This thread can handle 10 clients simultaneously. Then each new client sets the semaphore until it reaches 10. When the Semaphore has 10 flags, then your thread won't accept new connections
Mutex are usually used for guarding stuff. Suppose your 10 clients can access multiple parts of the system. Then you can protect a part of the system with a mutex so when 1 client is connected to that sub-system, no one else should have access. You can use a Semaphore for this purpose too. A mutex is a "Mutual Exclusion Semaphore".
For Gulp users, gulp-ng-constant is also useful combined with gulp-concat, event-stream and yargs.
var concat = require('gulp-concat'),
es = require('event-stream'),
gulp = require('gulp'),
ngConstant = require('gulp-ng-constant'),
argv = require('yargs').argv;
var enviroment = argv.env || 'development';
gulp.task('config', function () {
var config = gulp.src('config/' + enviroment + '.json')
.pipe(ngConstant({name: 'app.config'}));
var scripts = gulp.src('js/*');
return es.merge(config, scripts)
.pipe(concat('app.js'))
.pipe(gulp.dest('app/dist'))
.on('error', function() { });
});
In my config folder I have these files:
ls -l config
total 8
-rw-r--r--+ 1 .. ci.json
-rw-r--r--+ 1 .. development.json
-rw-r--r--+ 1 .. production.json
Then you can run gulp config --env development
and that will create something like this:
angular.module("app.config", [])
.constant("foo", "bar")
.constant("ngConstant", true);
I also have this spec:
beforeEach(module('app'));
it('loads the config', inject(function(config) {
expect(config).toBeTruthy();
}));
For the case where the TextView
is inside a TableLayout
, the solution is to set android:shrinkColumns="1"
on the TableLayout
. (Replace 1
with the column number the TextView you want to wrap is in. (0-indexed))
AFAICT, no other attributes are needed on the TextView
.
For other cases, see the other answers here.
FWIW, I had initially gotten it to sort of work with
<TextView
android:id="@+id/inventory_text"
android:layout_width="fill_parent"
android:layout_weight="1"
android:width="0dp"
but that resulted in some extra empty space at the bottom of the Dialog it was all in.
You can use Dynamic Function Name and parameters like this.
1) Define function Separate and call it
let functionName = "testFunction";
let param = {"param1":1 , "param2":2};
var func = new Function(
"return " + functionName
)();
func(param);
function testFunction(params){
alert(params.param1);
}
2) Define function code dynamic
let functionName = "testFunction(params)";
let param = {"param1":"1" , "param2":"2"};
let functionBody = "{ alert(params.param1)}";
var func = new Function(
"return function " + functionName + functionBody
)();
func(param);
var count=0;
document.getElementById("play").onclick = function(){
if(count%2 =="1"){
document.getElementById("video").pause();
document.getElementById("play").innerHTML ="Pause";
}else {
document.getElementById("video").play();
document.getElementById("play").innerHTML ="Play";
}
++count;
Based on the error message, your problem seems to be related to interpolation (typically your expression {{}}
), not to a cross-domain issue. Basically ng-src="{{object.src}}"
sucks.
ng-src
was designed with img
tag in mind IMO. It might not be appropriate for <source>
. See http://docs.angularjs.org/api/ng.directive:ngSrc
If you declare <source src="somesite.com/myvideo.mp4"; type="video/mp4"/>
, it will be working, right? (note that I remove ng-src
in favor of src
) If not it must be fixed first.
Then ensure that {{object.src}}
returns the expected value (outside of <video>
):
<span>{{object.src}}</span>
<video>...</video>
If it returns the expected value, the following statement should be working:
<source src="{{object.src}}"; type="video/mp4"/> //src instead of ng-src
While there are two excellent answers telling you how to do it, I feel that another answer is missing: In most cases you shouldn't do it at all.
Arrays are cumbersome, in most cases you are better off using the Collection API.
With Collections, you can add and remove elements and there are specialized Collections for different functionality (index-based lookup, sorting, uniqueness, FIFO-access, concurrency etc.).
While it's of course good and important to know about Arrays and their usage, in most cases using Collections makes APIs a lot more manageable (which is why new libraries like Google Guava hardly use Arrays at all).
So, for your scenario, I'd prefer a List of Lists, and I'd create it using Guava:
List<List<String>> listOfLists = Lists.newArrayList();
listOfLists.add(Lists.newArrayList("abc","def","ghi"));
listOfLists.add(Lists.newArrayList("jkl","mno","pqr"));
The .row
is meant to be used inside a container
. Since the container
has padding to adjust the negative margin in the .row
, grid columns used inside the .row
can then adjust to the full width of the container. See the Bootstrap docs: http://getbootstrap.com/css/#grid
Here's an example to illustrate: http://bootply.com/131054
So, a better solution may for you to place your .row
inside a .container
or .container-fluid
Very simple option in case you have many individual columns to delete in a data table and you want to avoid typing in all column names #careadviced
dt <- dt[, -c(1,4,6,17,83,104)]
This will remove columns based on column number instead.
It's obviously not as efficient because it bypasses data.table advantages but if you're working with less than say 500,000 rows it works fine
HTTP is called as a stateless protocol
because each request is executed independently, without any knowledge of the requests that were executed before it, which means once the transaction ends the connection between the browser and the server is also lost.
What makes the protocol stateless
is that in its original design, HTTP is a relatively simple file transfer protocol
:
There was no relationship maintained between one connection and another, even from the same client. This simplifies the contract between client and server, and in many cases minimizes the amount of data that needs to be transferred.
If you aren't totally sure what you mean by "uncommit" and don't know if you want to use git reset
, please see "Revert to a previous Git commit".
If you're trying to understand git reset
better, please see "Can you explain what "git reset" does in plain English?".
If you know you want to use git reset
, it still depends what you mean by "uncommit". If all you want to do is undo the act of committing, leaving everything else intact, use:
git reset --soft HEAD^
If you want to undo the act of committing and everything you'd staged, but leave the work tree (your files intact):
git reset HEAD^
And if you actually want to completely undo it, throwing away all uncommitted changes, resetting everything to the previous commit (as the original question asked):
git reset --hard HEAD^
The original question also asked it's HEAD^
not HEAD
. HEAD
refers to the current commit - generally, the tip of the currently checked-out branch. The ^
is a notation which can be attached to any commit specifier, and means "the commit before". So, HEAD^
is the commit before the current one, just as master^
is the commit before the tip of the master branch.
Here's the portion of the git-rev-parse documentation describing all of the ways to specify commits (^
is just a basic one among many).
This worked for me:
for n in tf.get_default_graph().as_graph_def().node:
print('\n',n)
While several answers are similar, I still had an issue - the user would click the button several times, playing the audio over itself (either it was clicked by accident or they were just 'playing'....)
An easy fix:
var music = new Audio();
function playMusic(file) {
music.pause();
music = new Audio(file);
music.play();
}
Setting up the audio on load allowed 'music' to be paused every time the function is called - effectively stopping the 'noise' even if they user clicks the button several times (and there is also no need to turn off the button, though for user experience it may be something you want to do).
Small tweak to Luke's answer,
function reloadJs(src) {
src = $('script[src$="' + src + '"]').attr("src");
$('script[src$="' + src + '"]').remove();
$('<script/>').attr('src', src).appendTo('head');
}
and call it like,
reloadJs("myFile.js");
This will not have any path related issues.
Here is the cleanest way to do this:
<p ng-show="{{foo === undefined}}">Show this if $scope.foo === undefined</p>
No need to create a helper function in the controller!
Well, now you know there is a problem, the next step is to figure out what exactly the error is, what happens when you compile and run this?:
#include <stdio.h>
#include <stdlib.h>
int main(void)
{
FILE *file;
file = fopen("TestFile1.txt", "r");
if (file == NULL) {
perror("Error");
} else {
fclose(file);
}
}
If you put return statement in if
, while
or for
statement then it may or may not return value. If it will not go inside these statement then also that method should return some value ( that could be null). To ensure that, compiler will force you to write this return statement which is after if
, while
or for
.
But if you write if
/ else
block and each one of them is having return in it then compiler knows that either if
or else
will get execute and method will return a value. So this time compiler will not force you.
if(condition)
{
return;
}
else
{
return;
}
You can also try this in plain javascript
"1234".slice(0,-1)
the negative second parameter is an offset from the last character, so you can use -2 to remove last 2 characters etc
Not so pretty but works with default settings and for the first line as well:
String query = "" +
"SELECT FOO, BAR, BAZ" +
" FROM ABC " +
" WHERE BAR > 4 ";
You can give a function expression a name that is actually private and is only visible from inside of the function ifself:
var factorial = function myself (n) {
if (n <= 1) {
return 1;
}
return n * myself(n-1);
}
typeof myself === 'undefined'
Here myself
is visible only inside of the function itself.
You can use this private name to call the function recursively.
See 13. Function Definition
of the ECMAScript 5 spec:
The Identifier in a FunctionExpression can be referenced from inside the FunctionExpression's FunctionBody to allow the function to call itself recursively. However, unlike in a FunctionDeclaration, the Identifier in a FunctionExpression cannot be referenced from and does not affect the scope enclosing the FunctionExpression.
Please note that Internet Explorer up to version 8 doesn't behave correctly as the name is actually visible in the enclosing variable environment, and it references a duplicate of the actual function (see patrick dw's comment below).
Alternatively you could use arguments.callee
to refer to the current function:
var factorial = function (n) {
if (n <= 1) {
return 1;
}
return n * arguments.callee(n-1);
}
The 5th edition of ECMAScript forbids use of arguments.callee() in strict mode, however:
(From MDN): In normal code arguments.callee refers to the enclosing function. This use case is weak: simply name the enclosing function! Moreover, arguments.callee substantially hinders optimizations like inlining functions, because it must be made possible to provide a reference to the un-inlined function if arguments.callee is accessed. arguments.callee for strict mode functions is a non-deletable property which throws when set or retrieved.
How do I properly compare strings?
char input[40];
char check[40];
strcpy(input, "Hello"); // input assigned somehow
strcpy(check, "Hello"); // check assigned somehow
// insufficient
while (check != input)
// good
while (strcmp(check, input) != 0)
// or
while (strcmp(check, input))
Let us dig deeper to see why check != input
is not sufficient.
In C, string is a standard library specification.
A string is a contiguous sequence of characters terminated by and including the first null character.
C11 §7.1.1 1
input
above is not a string. input
is array 40 of char.
The contents of input
can become a string.
In most cases, when an array is used in an expression, it is converted to the address of its 1st element.
The below converts check
and input
to their respective addresses of the first element, then those addresses are compared.
check != input // Compare addresses, not the contents of what addresses reference
To compare strings, we need to use those addresses and then look at the data they point to.
strcmp()
does the job. §7.23.4.2
int strcmp(const char *s1, const char *s2);
The
strcmp
function compares the string pointed to bys1
to the string pointed to bys2
.The
strcmp
function returns an integer greater than, equal to, or less than zero, accordingly as the string pointed to bys1
is greater than, equal to, or less than the string pointed to bys2
.
Not only can code find if the strings are of the same data, but which one is greater/less when they differ.
The below is true when the string differ.
strcmp(check, input) != 0
For insight, see Creating my own strcmp()
function
Sairam With the samples given above, I have tried & came out with the script which I wanted. The position parameters mentioned in other example gave different results. I wanted to create one Batch file to take the Oracle data backup (export data) on daily basis, preserving distinct DMP files with date & time as part of file name. Here is the script which worked well:
cls
set dt=%date:~0,2%%date:~3,2%%date:~6,4%-%time:~0,2%%time:~3,2%
set fn=backup-%dt%.DMP
echo %fn%
pause A
exp user/password file=D:\DATA_DMP\%fn%
Now with react-router v15.1
and onwards we can useHistory
hook, This is super simple and clear way. Here is a simple example from the source blog.
import { useHistory } from "react-router-dom";
function BackButton({ children }) {
let history = useHistory()
return (
<button type="button" onClick={() => history.goBack()}>
{children}
</button>
)
}
You can use this within any functional component and custom hooks. And yes this will not work with class components same as any other hook.

I've today made quite a few changes to my rails schema. I realised I needed an additional two models in a hierarchy and some others to be deleted. There were many little changes required to the models and controllers.
I added the two new models and created them, using:
rake db:migrate
Then I edited the schema.rb file. I manually removed the old models that were no longer required, changed the foreign key field as required and just reordered it a bit to make it clearer to me. I deleted all the migrations, and then re-ran the build via:
rake db:reset
It worked perfectly. All the data has to be reloaded, of course. Rails realised the migrations had been deleted and reset the high-water mark:
-- assume_migrated_upto_version(20121026094813, ["/Users/sean/rails/f4/db/migrate"])
Another way of doing it with AudioInputStream
:
import java.io.File;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;
import javax.sound.sampled.Line;
import javax.sound.sampled.LineEvent;
import javax.sound.sampled.LineListener;
import javax.swing.JDialog;
import javax.swing.JFileChooser;
public class CoreJavaSound extends Object implements LineListener {
File soundFile;
JDialog playingDialog;
Clip clip;
public static void main(String[] args) throws Exception {
CoreJavaSound s = new CoreJavaSound();
}
public CoreJavaSound() throws Exception {
JFileChooser chooser = new JFileChooser();
chooser.showOpenDialog(null);
soundFile = chooser.getSelectedFile();
System.out.println("Playing " + soundFile.getName());
Line.Info linfo = new Line.Info(Clip.class);
Line line = AudioSystem.getLine(linfo);
clip = (Clip) line;
clip.addLineListener(this);
AudioInputStream ais = AudioSystem.getAudioInputStream(soundFile);
clip.open(ais);
clip.start();
}
public void update(LineEvent le) {
LineEvent.Type type = le.getType();
if (type == LineEvent.Type.OPEN) {
System.out.println("OPEN");
} else if (type == LineEvent.Type.CLOSE) {
System.out.println("CLOSE");
System.exit(0);
} else if (type == LineEvent.Type.START) {
System.out.println("START");
playingDialog.setVisible(true);
} else if (type == LineEvent.Type.STOP) {
System.out.println("STOP");
playingDialog.setVisible(false);
clip.close();
}
}
}
Use the "has attribute" selector:
$('p[MyTag]')
Or to select one where that attribute has a specific value:
$('p[MyTag="Sara"]')
There are other selectors for "attribute value starts with", "attribute value contains", etc.
Actually, there is a way. You just need to copy DeviceSupport folder for iOS 7.1 from Older Xcode to the new one. It's located in:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/7.1
If you don't have the 7.1 files anymore, you can download a previous version of XCode on https://developer.apple.com/download/more/, extract it, and then copy these files to following path
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/
Iterating over a dictionary object itself actually gives you an iterator over its keys. Python is trying to unpack keys, which you get from m.type + m.purity
into (m, k)
.
My crystal ball says m.type
and m.purity
are both strings, so your keys are also strings. Strings are iterable, so they can be unpacked; but iterating over the string gives you an iterator over its characters. So whenever m.type + m.purity
is more than two characters long, you have too many values to unpack. (And whenever it's shorter, you have too few values to unpack.)
To fix this, you can iterate explicitly over the items
of the dict, which are the (key, value) pairs that you seem to be expecting. But if you only want the values, then just use the values.
(In 2.x, itervalues
, iterkeys
, and iteritems
are typically a better idea; the non-iter
versions create a new list object containing the values/keys/items. For large dictionaries and trivial tasks within the iteration, this can be a lot slower than the iter
versions which just set up an iterator.)
If I have one thing that I love to share with respect to CSS, it's MY FAVE WAY OF CENTERING THINGS ALONG BOTH AXES!!!
Advantages of this method:
I always do this by using 2 classes: One to specify the parent element, whose content will be centered (.centered-wrapper
), and the 2nd one to specify which child of the parent is centered (.centered-content
). This 2nd class is useful in the case where the parent has multiple children, but only 1 needs to be centered).
In this case, body
will be the .centered-wrapper
, and an inner div
will be .centered-content
.
<html>
<head>...</head>
<body class="centered-wrapper">
<div class="centered-content">...</div>
</body>
</html>
The idea for centering will now be to make .centered-content
an inline-block
. This will easily facilitate horizontal centering, through text-align: center;
, and also allows for vertical centering as you shall see.
.centered-wrapper {
position: relative;
text-align: center;
}
.centered-wrapper:before {
content: "";
position: relative;
display: inline-block;
width: 0; height: 100%;
vertical-align: middle;
}
.centered-content {
display: inline-block;
vertical-align: middle;
}
This gives you 2 really reusable classes for centering any child inside of any parent! Just add the .centered-wrapper
and .centered-content
classes.
So, what's up with that :before
element? It facilitates vertical-align: middle;
and is necessary because vertical alignment isn't relative to the height of the parent - vertical alignment is relative to the height of the tallest sibling!!!. Therefore, by ensuring that there is a sibling whose height is the parent's height (100% height, 0 width to make it invisible), we know that vertical alignment will be with respect to the parent's height.
One last thing: You need to ensure that your html
and body
tags are the size of the window so that centering to them is the same as centering to the browser!
html, body {
width: 100%;
height: 100%;
padding: 0;
margin: 0;
}
The problem was that the working copy was checked out via svn+ssh (thanks, Thomas). Instead of setting up ssh keys as was suggested, I just checked out a new working copy using svn://domain.com/path/to/repo rather than svn+ssh://domain.com/path/to/repo. Because this working copy is on the same machine as the repository itself, I'm not really missing out on anything, and I can now use the --password and --username options gratuitously. Seems obvious now that I think about it.

When deciding whether to make a class static or non-static you need to look at what information you are trying to represent. This entails a more 'bottom-up' style of programming where you focus on the data you are representing first. Is the class you are writing a real-world object like a rock, or a chair? These things are physical and have physical attributes such as color, weight which tells you that you may want to instantiate multiple objects with different properties. I may want a black chair AND a red chair at the same time. If you ever need two configurations at the same time then you instantly know you will want to instantiate it as an object so each object can be unique and exist at the same time.
On the other end, static functions tend to lend more to actions which do not belong to a real-world object or an object that you can easily represent. Remember that C#'s predecessors are C++ and C where you can just define global functions that do not exist in a class. This lends more to 'top-down' programming. Static methods can be used for these cases where it doesn't make sense that an 'object' performs the task. By forcing you to use classes this just makes it easier to group related functionality which helps you create more maintainable code.
Most classes can be represented by either static or non-static, but when you are in doubt just go back to your OOP roots and try to think about what you are representing. Is this an object that is performing an action (a car that can speed up, slow down, turn) or something more abstract (like displaying output).
Get in touch with your inner OOP and you can never go wrong!
MVC 4 @Html.CheckBoxFor generally people want to action on check and uncheck of mvc checkbox.
<div class="editor-field"> @Html.CheckBoxFor(model => model.IsAll, new { id = "cbAllEmp" }) </div>
you can define id for the controls you want to change and in javascript do the folowing
<script type="text/javascript">
$(function () {
$("#cbAllEmp").click("", function () {
if ($("#cbAllEmp").prop("checked") == true) {
$("#txtEmpId").hide();
$("#lblEmpId").hide();
}
else {
$("#txtEmpId").show();
$("#txtEmpId").val("");
$("#lblEmpId").show();
}
});
});
you can also change the property like
$("#txtEmpId").prop("disabled", true);
$("#txtEmpId").prop("readonly", true);
Now that you have provided your HTML sample, we're able to see that your XPath is slightly wrong. While it's valid XPath, it's logically wrong.
You've got:
//*[contains(@id, 'ctl00_btnAircraftMapCell')]//*[contains(@title, 'Select Seat')]
Which translates into:
Get me all the elements that have an ID
that contains ctl00_btnAircraftMapCell
. Out of these elements, get any child elements that have a title
that contains Select Seat
.
What you actually want is:
//a[contains(@id, 'ctl00_btnAircraftMapCell') and contains(@title, 'Select Seat')]
Which translates into:
Get me all the anchor elements that have both: an id
that contains ctl00_btnAircraftMapCell
and a title
that contains Select Seat
.

Thanks guys, I used a combination of both your answers @Christian and @Jonathan for my specific need.
"http://" + Request.ServerVariables["SERVER_NAME"] + Request.RawUrl.ToString()
I don't need to worry about secure http, needed the servername variable and the RawUrl handles the path from the domain name and includes the querystring if present.
I also faced a similar issue. The reason was that I had the changes done in the .aspx page but not the designer page and hence I got the mentioned error. When the reference was created in the designer page I was able to build the solution.
Try This
ImagePath = "http://localhost/profilepics/abc.png";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(ImagePath);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream receiveStream = response.GetResponseStream();
Set the anchor property of the control to hook to all sides of the parent - top, bottom, left, and right.
You'll want to listen for escape's keyCode
(27) from the React SyntheticKeyBoardEvent
onKeyDown
:
const EscapeListen = React.createClass({
handleKeyDown: function(e) {
if (e.keyCode === 27) {
console.log('You pressed the escape key!')
}
},
render: function() {
return (
<input type='text'
onKeyDown={this.handleKeyDown} />
)
}
})
Brad Colthurst's CodePen posted in the question's comments is helpful for finding key codes for other keys.
Firstly, I believe that trying to do several things at once is a bad practice in general and I suggest you think over what you are trying to achieve.

in the latest version of android studio, you can just do:
./gradlew assembleRelease
or aR
for short. This will produce an unsigned release apk. Building a signed apk can be done similarly or you can use Build -> Generate Signed Apk in Android Studio.
Here is my build.gradle for reference:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.5.+'
}
}
apply plugin: 'android'
dependencies {
compile fileTree(dir: 'libs', include: '*.jar')
}
android {
compileSdkVersion 17
buildToolsVersion "17.0.0"
sourceSets {
main {
manifest.srcFile 'AndroidManifest.xml'
java.srcDirs = ['src']
resources.srcDirs = ['src']
aidl.srcDirs = ['src']
renderscript.srcDirs = ['src']
res.srcDirs = ['res']
assets.srcDirs = ['assets']
}
// Move the tests to tests/java, tests/res, etc...
instrumentTest.setRoot('tests')
// Move the build types to build-types/<type>
// For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
// This moves them out of them default location under src/<type>/... which would
// conflict with src/ being used by the main source set.
// Adding new build types or product flavors should be accompanied
// by a similar customization.
debug.setRoot('build-types/debug')
release.setRoot('build-types/release')
}
buildTypes {
release {
}
}
My answer is a bit different because I've tried these methods but they didn't work. My code uses an extra class that checks for a Boolean flag in a public static class as the database values are read or where I prefer it just before an object is added to a List object or something as such. See the change in the code below. I added the ThreadWatcher.StopThread property. for this explation I'm nog going to reinstate the current thread because it's not your issue but that's as easy as setting the property to false before accessing the next thread...
private void combobox2_TextChanged(object sender, EventArgs e)
{
//Stop the thread here with this
ThreadWatcher.StopThread = true;//the rest of this thread will run normally after the database function has stopped.
if (cmbDataSourceExtractor.IsBusy)
cmbDataSourceExtractor.CancelAsync();
while(cmbDataSourceExtractor.IsBusy)
Application.DoEvents();
var filledComboboxValues = new FilledComboboxValues{ V1 = combobox1.Text,
V2 = combobox2.Text};
cmbDataSourceExtractor.RunWorkerAsync(filledComboboxValues );
}
all fine
private void cmbDataSourceExtractor_DoWork(object sender, DoWorkEventArgs e)
{
if (this.cmbDataSourceExtractor.CancellationPending)
{
e.Cancel = true;
return;
}
// do stuff...
}
Now add the following class
public static class ThreadWatcher
{
public static bool StopThread { get; set; }
}
and in your class where you read the database
List<SomeObject>list = new List<SomeObject>();
...
if (!reader.IsDbNull(0))
something = reader.getString(0);
someobject = new someobject(something);
if (ThreadWatcher.StopThread == true)
break;
list.Add(something);
...
don't forget to use a finally block to properly close your database connection etc. Hope this helps! Please mark me up if you find it helpful.
The my.cnf file you should edit is the /etc/mysql/my.cnf file. Just:
sudo nano /etc/mysql/my.cnf
Then add:
[mysqld]
local-infile
[mysql]
local-infile
The headers [mysqld] and [mysql] are already given, just locate them in the file and add local-infile underneath each of them.
It works for me on MySQL 5.5 on Ubuntu 12.04 LTS.
I have got same error for Android-28. In SDK manager - SDK Platform it shows me that Android API 28 is partially installed and no further updates available. so that I updated ANDROID-SDK-BUILD-TOOLS from SDK Tools and after restarting project. It will work. This might be helpful for other who faces same issue as I faced.
It can also be used as below:
from datetime import datetime
start_date = datetime(2016,3,1)
end_date = datetime(2016,3,10)
Although I generally agree that the named arguments approach is useful and flexible (unless you care about the order, in which case arguments is easiest), I do have concerns about the cost of the mbeasley approach (using defaults and extends). This is an extreme amount of cost to take for pulling default values. First, the defaults are defined inside the function, so they are repopulated on every call. Second, you can easily read out the named values and set the defaults at the same time using ||. There is no need to create and merge yet another new object to get this information.
function load(context) {
var parameter1 = context.parameter1 || defaultValue1,
parameter2 = context.parameter2 || defaultValue2;
// do stuff
}
This is roughly the same amount of code (maybe slightly more), but should be a fraction of the runtime cost.
$dbc
is returning false. Your query has an error in it:
SELECT users.*, profile.* --You do not join with profile anywhere.
FROM users
INNER JOIN contact_info
ON contact_info.user_id = users.user_id
WHERE users.user_id=3");
The fix for this in general has been described by Raveren.
public static String[] textSort(String[] words) {
for (int i = 0; i < words.length; i++) {
for (int j = i + 1; j < words.length; j++) {
if (words[i].compareTo(words[j]) > 0) {
String temp = words[i];
words[i] = words[j];
words[j] = temp;
}
}
}
return words;
}
If you don't want to alter the CSS file, this is what works for me. In HTML, add style with color:
<i class="fa fa-cog" style="color:#fff;"></i>
The current windows 10 (Version 1803 (OS Build 17134.1)) has SSH built in. With that, just enable SSH from the Control Panel, Terminal & SNMP, be sure you are using an account in the Administrator's group, and you're all set.
Launch Powershell or CMD, enter ssh yourAccountName@diskstation
The first time it will cache off your certificate.
Further detailed explanations can be found on the synology docs page:
For those talking about doing this in C++ which doesn't necessarily support the C99 extensions, then I heartily recommend boost::format. This makes the size_t type size question moot:
std::cout << boost::format("Sizeof(Var) is %d\n") % sizeof(Var);
Since you don't need size specifiers in boost::format, you can just worry about how you want to display the value.
You can't use it in the way you describe. The point about generic types, is that although you may not know them at "coding time", the compiler needs to be able to resolve them at compile time. Why? Because under the hood, the compiler will go away and create a new type (sometimes called a closed generic type) for each different usage of the "open" generic type.
In other words, after compilation,
DoesEntityExist<int>
is a different type to
DoesEntityExist<string>
This is how the compiler is able to enfore compile-time type safety.
For the scenario you describe, you should pass the type as an argument that can be examined at run time.
The other option, as mentioned in other answers, is that of using reflection to create the closed type from the open type, although this is probably recommended in anything other than extreme niche scenarios I'd say.

.
input . valueAsNumber [ = value ]
Returns a number representing the form control's value, if applicable; otherwise, returns null.
Can be set, to change the value.
Throws an INVALID_STATE_ERR exception if the control is neither date- or time-based nor numeric.
It is a unary "+" operator which yields a numeric expression. It would be the same as d*1
, I believe.
std::map
takes up to four template type arguments, the third one being a comparator. E.g.:
struct cmpByStringLength {
bool operator()(const std::string& a, const std::string& b) const {
return a.length() < b.length();
}
};
// ...
std::map<std::string, std::string, cmpByStringLength> myMap;
Alternatively you could also pass a comparator to map
s constructor.
Note however that when comparing by length you can only have one string of each length in the map as a key.
When creating a custom rating bar that displays a solid gradient line running on a SeekBar-like track, rather than stars, I also encountered a problem related to the vertical centering of the background (track drawable). This is the flawed drawable code I used originally (which generated the problem), as suggested by Android developer and other StackOverflow entries:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="@android:id/background"
android:drawable="@drawable/seekbar_track"/>
<item android:id="@android:id/secondaryProgress">
<scale
android:drawable="@drawable/seekbar_progress2"
android:scaleWidth="100%" />
</item>
<item android:id="@android:id/progress" >
<clip android:clipOrientation="horizontal" android:gravity="left" >
<shape>
<gradient
android:startColor="@color/ratingbar_bg_start"
android:centerColor="@color/ratingbar_bg_center"
android:centerX="0.5"
android:endColor="@color/ratingbar_bg_end"
android:angle="0"
/>
</shape>
</clip>
</item>
</layer-list>
The problem here is the first item, which relates to the background of the custom RatingBar. Many entries will tell you to set the layout_minHeight feature to some large value to avoid a vertical spatial disconnect between the thumb and its track. This was not the solution for me - when viewed on a tablet, the background was still drawing to its smaller phone-based size - so the track was consistently positioned well above the center of the RatingBar track. The solution is to remove this entry in the RatingBar drawable, so it now looks like this:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@android:id/secondaryProgress">
<scale
android:drawable="@drawable/seekbar_progress2"
android:scaleWidth="100%" />
</item>
<item android:id="@android:id/progress" >
<clip android:clipOrientation="horizontal" android:gravity="left" >
<shape>
<gradient
android:startColor="@color/ratingbar_bg_start"
android:centerColor="@color/ratingbar_bg_center"
android:centerX="0.5"
android:endColor="@color/ratingbar_bg_end"
android:angle="0"
/>
</shape>
</clip>
</item>
</layer-list>
Then, in the style definition of the custom RatingBar, set the layout_background to the the track drawable. Mine looks like this:
<style name="styleRatingBar" parent="@android:style/Widget.RatingBar">
<item name="android:indeterminateOnly">false</item>
<item name="android:background">@drawable/seekbar_track</item>
<item name="android:progressDrawable">@drawable/abratingbar</item>
<item name="android:thumb">@drawable/abseekbar_thumb</item>
<item name="android:minHeight">@dimen/base_29dp</item>
<item name="android:maxHeight">@dimen/base_29dp</item>
<item name="android:layout_marginLeft">@dimen/base_10dp</item>
<item name="android:layout_marginRight">@dimen/base_10dp</item>
<item name="android:layout_marginTop">@dimen/base_10dp</item>
<item name="android:layout_marginBottom">@dimen/base_10dp</item>
<item name="android:scaleType">fitXY</item>
</style>
(Previously, the background setting here was undefined.).
This is the entry in my layout, which uses both the style and the drawables:
<RatingBar
android:id="@+id/ratingbar_vote"
style="@style/styleRatingBar"
android:hint="@string/ratingbar_vote"
android:contentDescription="@string/ratingbar_vote"
android:numStars="5"
android:rating="5"
android:stepSize="1"
android:layout_width="match_parent"
android:layout_height="@dimen/base_29dp"
android:layout_marginLeft="@dimen/base_120dp"
android:layout_gravity="bottom|right" />
So, to summarize, do not set the background (track) feature in your custom RatingBar drawable, set it in the layout_background feature of your custom RatingBar style. This ensures the track is always vertically centered in a horizontal RatingBar. (Remember, in this custom RatingBar, instead of using stars or other isolated images as the rating, I'm using a gradient line that "grows" or "shrinks" horizontally to display the rating - this rating line uses a SeekBar-like thumb running on a SeekBar-like "track".)
With the -cp
argument you provide the classpath i.e. path(s) to additional classes or libraries that your program may require when being compiled or run. With -jar
you specify the executable JAR file that you want to run.
You can't specify them both. If you try to run java -cp folder/myexternallibrary.jar -jar myprogram.jar
then it won't really work. The classpath for that JAR should be specified in its Manifest, not as a -cp
argument.
You can find more about this here and here.
PS: -cp
and -classpath
are synonyms.
I found lots of people meet this problem because the Multi-version Python, on my own vps (cent os 7 x64), I solved it in this way:
Find the file "_sqlite3.so"
find / -name _sqlite3.so
out: /usr/lib64/python2.7/lib-dynload/_sqlite3.so
Find the dir of python Standard library you want to use,
for me /usr/local/lib/python3.6/lib-dynload
Copy the file:
cp /usr/lib64/python2.7/lib-dynload/_sqlite3.so /usr/local/lib/python3.6/lib-dynload
Finally, everything will be ok.
You are reinventing the wheel. Normal PowerShell scripts have parameters starting with -
, like script.ps1 -server http://devserver
Then you handle them in param
section in the beginning of the file.
You can also assign default values to your params, read them from console if not available or stop script execution:
param (
[string]$server = "http://defaultserver",
[Parameter(Mandatory=$true)][string]$username,
[string]$password = $( Read-Host "Input password, please" )
)
Inside the script you can simply
write-output $server
since all parameters become variables available in script scope.
In this example, the $server
gets a default value if the script is called without it, script stops if you omit the -username
parameter and asks for terminal input if -password
is omitted.
Update: You might also want to pass a "flag" (a boolean true/false parameter) to a PowerShell script. For instance, your script may accept a "force" where the script runs in a more careful mode when force is not used.
The keyword for that is [switch]
parameter type:
param (
[string]$server = "http://defaultserver",
[string]$password = $( Read-Host "Input password, please" ),
[switch]$force = $false
)
Inside the script then you would work with it like this:
if ($force) {
//deletes a file or does something "bad"
}
Now, when calling the script you'd set the switch/flag parameter like this:
.\yourscript.ps1 -server "http://otherserver" -force
If you explicitly want to state that the flag is not set, there is a special syntax for that
.\yourscript.ps1 -server "http://otherserver" -force:$false
Links to relevant Microsoft documentation (for PowerShell 5.0; tho versions 3.0 and 4.0 are also available at the links):
I know this is an old question, but gracchus's solution doesn't work if file names contain spaces. VonC's solution to file names with spaces is to not remove them utilizing --ignore-unmatch
, then remove them manually, but this will not work well if there are a lot.
Here is a solution that utilizes bash arrays to capture all files.
# Build bash array of the file names
while read -r file; do
rmlist+=( "$file" )
done < <(git ls-files -i --exclude-standard)
git rm –-cached "${rmlist[@]}"
git commit -m 'ignore update'
Not mentioned as of yet:
The unsort
util. Syntax (somewhat playlist oriented):
unsort [-hvrpncmMsz0l] [--help] [--version] [--random] [--heuristic]
[--identity] [--filenames[=profile]] [--separator sep] [--concatenate]
[--merge] [--merge-random] [--seed integer] [--zero-terminated] [--null]
[--linefeed] [file ...]
msort
can shuffle by line, but it's usually overkill:
seq 10 | msort -jq -b -l -n 1 -c r
Not to hammer on this or anything but for ES5-compliant browsers why not just:
function isDOM(e) {
return (/HTML(?:.*)Element/).test(Object.prototype.toString.call(e).slice(8, -1));
}
Won't work on TextNodes and not sure about Shadow DOM or DocumentFragments etc. but will work on almost all HTML tag elements.
Here's a more comprehensive solution to the disconnect selection, and the cancellation of some of the hot keys (such as Ctrl+a and Ctrl+c. Test: Cmd+a and Cmd+c)
(function($){
$.fn.ctrlCmd = function(key) {
var allowDefault = true;
if (!$.isArray(key)) {
key = [key];
}
return this.keydown(function(e) {
for (var i = 0, l = key.length; i < l; i++) {
if(e.keyCode === key[i].toUpperCase().charCodeAt(0) && e.metaKey) {
allowDefault = false;
}
};
return allowDefault;
});
};
$.fn.disableSelection = function() {
this.ctrlCmd(['a', 'c']);
return this.attr('unselectable', 'on')
.css({'-moz-user-select':'-moz-none',
'-moz-user-select':'none',
'-o-user-select':'none',
'-khtml-user-select':'none',
'-webkit-user-select':'none',
'-ms-user-select':'none',
'user-select':'none'})
.bind('selectstart', false);
};
})(jQuery);
and call example:
$(':not(input,select,textarea)').disableSelection();
This could be also not enough for old versions of FireFox (I can't tell which). If all this does not work, add the following:
.on('mousedown', false)
Because the statement defining obj
hasn't finished, key1
doesn't exist yet. Consider this solution:
var obj = { key1: "it" };
obj.key2 = obj.key1 + ' ' + 'works!';
// obj.key2 is now 'it works!'
Maybe you need unique temporary file?
import tempfile
f = tempfile.NamedTemporaryFile(mode='w+b', delete=False)
print f.name
f.close()
f is opened file. delete=False
means do not delete file after closing.
If you need control over the name of the file, there are optional prefix=...
and suffix=...
arguments that take strings. See https://docs.python.org/3/library/tempfile.html.
As other people have answered, .cshtml
(or .vbhtml
if that's your flavor) provides a handler-mapping to load the MVC engine. The .aspx
extension simply loads the aspnet_isapi.dll that performs the compile and serves up web forms. The difference in the handler mapping is simply a method of allowing the two to co-exist on the same server allowing both MVC applications and WebForms applications to live under a common root.
This allows http://www.mydomain.com/MyMVCApplication to be valid and served with MVC rules along with http://www.mydomain.com/MyWebFormsApplication to be valid as a standard web form.
Edit:
As for the difference in the technologies, the MVC (Razor) templating framework is intended to return .Net pages to a more RESTful "web-based" platform of templated views separating the code logic between the model (business/data objects), the view (what the user sees) and the controllers (the connection between the two). The WebForms model (aspx) was an attempt by Microsoft to use complex javascript embedding to simulate a more stateful application similar to a WinForms application complete with events and a page lifecycle that would be capable of retaining its own state from page to page.
The choice to use one or the other is always going to be a contentious one because there are arguments for and against both systems. I for one like the simplicity in the MVC architecture (though routing is anything but simple) and the ease of the Razor syntax. I feel the WebForms architecture is just too heavy to be an effective web platform. That being said, there are a lot of instances where the WebForms framework provides a very succinct and usable model with a rich event structure that is well defined. It all boils down to the needs of the application and the preferences of those building it.

Move your code inside the closure and use $ instead of jQuery

unique_ptr
is a smart pointer which owns an object exclusively.
shared_ptr
is a smart pointer for shared ownership. It is both copyable
and movable
. Multiple smart pointer instances can own the same resource. As soon as the last smart pointer owning the resource goes out of scope, the resource will be freed.
You can use the Sum
function, but you'll have to convert the strings to integers, like so:
int total = monValues.Sum(x => Convert.ToInt32(x));
I use @gnarf's method, though I fall back on document.writeln
ing a <script>
tag for IE<7 as I couldn't get DOM creation to work reliably in IE6 (and TBH didn't care enough to put much effort into it). The core of my code is:
if (horus.script.broken) {
document.writeln('<script type="text/javascript" src="'+script+'"></script>');
horus.script.loaded(script);
} else {
var s=document.createElement('script');
s.type='text/javascript';
s.src=script;
s.async=true;
if (horus.brokenDOM){
s.onreadystatechange=
function () {
if (this.readyState=='loaded' || this.readyState=='complete'){
horus.script.loaded(script);
}
}
}else{
s.onload=function () { horus.script.loaded(script) };
}
document.head.appendChild(s);
}
where horus.script.loaded()
notes that the javascript file is loaded, and calls any pending uncalled routines (saved by autoloader code).
Much like leonardocsouza, I had the same problem. To clarify a bit, this is what my folder structure looked like when I ran node server.js
node_modules/
app/
index.html
server.js
After printing out the __dirname
path, I realized that the __dirname
path was where my server was running (app/
).
So, the answer to your question is this:
If your server.js
file is in the same folder as the files you are trying to render, then
app.use( express.static( path.join( application_root, 'site') ) );
should actually be
app.use(express.static(application_root));
The only time you would want to use the original syntax that you had would be if you had a folder tree like so:
app/
index.html
node_modules
server.js
where index.html
is in the app/
directory, whereas server.js
is in the root directory (i.e. the same level as the app/
directory).
Side note: Intead of calling the path
utility, you can use the syntax application_root + 'site'
to join a path.
Overall, your code could look like:
// Module dependencies.
var application_root = __dirname,
express = require( 'express' ), //Web framework
mongoose = require( 'mongoose' ); //MongoDB integration
//Create server
var app = express();
// Configure server
app.configure( function() {
//Don't change anything here...
//Where to serve static content
app.use( express.static( application_root ) );
//Nothing changes here either...
});
//Start server --- No changes made here
var port = 5000;
app.listen( port, function() {
console.log( 'Express server listening on port %d in %s mode', port, app.settings.env );
});
You need to use the __getitem__
method.
class MyClass:
def __getitem__(self, key):
return key * 2
myobj = MyClass()
myobj[3] #Output: 6
And if you're going to be setting values you'll need to implement the __setitem__
method too, otherwise this will happen:
>>> myobj[5] = 1
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: MyClass instance has no attribute '__setitem__'
Not necessarily the best practice, but my environment was a local network with several machines which needed access to the selenium.
When running the chromedriver, you can pass through a param like so :
chromedriver --whitelisted-ips=""
This will basically whitelist all IP's, not always an ideal solution of course and be careful with it for production enviornments, but you should be presented with a verbose warning :
Starting ChromeDriver 2.16.333244 (15fb740a49ab3660b8f8d496cfab2e4d37c7e6ca) on port 9515 All remote connections are allowed. Use a whitelist instead!
A work-around at best, but it works.
If you still face problems, try the following:
sudo ufw enable
sudo apt-get install openssh-server
This might work too.
Also you can try opensource WebRTC Media Server Kurento
Which can play RTSP video stream and send it to WebRTC or transcode to RTMP or saving on server.
We are useing it on Production for the following cases:
- WebRTC to Webrtc (many to many) - WebRTC to RTMP - RTSP to WebRTC
Since R is already installed, you should be able to upgrade it with this method. First of all, you may want to have the packages you installed in the previous version in the new one,so it is convenient to check this post. Then, follow the instructions from here
Open the sources.list
file:
sudo nano /etc/apt/sources.list
Add a line with the source from where the packages will be retrieved. For example:
deb https://cloud.r-project.org/bin/linux/ubuntu/ version/
Replace https://cloud.r-project.org
with whatever mirror you would like to use, and replace
version/
with whatever version of Ubuntu you are using (eg, trusty/
, xenial/
, and so on). If you're getting a "Malformed line error", check to see if you have a space between /ubuntu/
and version/
.
Fetch the secure APT key:
gpg --keyserver keyserver.ubuntu.com --recv-key E298A3A825C0D65DFD57CBB651716619E084DAB9
or
gpg --hkp://keyserver keyserver.ubuntu.com:80 --recv-key E298A3A825C0D65DFD57CBB651716619E084DAB9
Add it to keyring:
gpg -a --export E084DAB9 | sudo apt-key add -
Update your sources and upgrade your installation:
sudo apt-get update && sudo apt-get upgrade
Install the new version
sudo apt-get install r-base-dev
Recover your old packages following the solution that best suits to you (see this). For instance, to recover all the packages (not only those from CRAN) the idea is:
-- copy the packages from R-oldversion/library
to R-newversion/library
, (do not overwrite a package if it already exists in the new version!).
-- Run the R command update.packages(checkBuilt=TRUE, ask=FALSE)
.
Quoting http://php.net/manual/en/intro.mssql.php:
The MSSQL extension is not available anymore on Windows with PHP 5.3 or later. SQLSRV, an alternative driver for MS SQL is available from Microsoft: » http://msdn.microsoft.com/en-us/sqlserver/ff657782.aspx.
Once you downloaded that, follow the instructions at this page:
In a nutshell:

The PHP Manual for the SQLSRV extension is located at http://php.net/manual/en/sqlsrv.installation.php and offers the following for Installation:
The SQLSRV extension is enabled by adding appropriate DLL file to your PHP extension directory and the corresponding entry to the php.ini file. The SQLSRV download comes with several driver files. Which driver file you use will depend on 3 factors: the PHP version you are using, whether you are using thread-safe or non-thread-safe PHP, and whether your PHP installation was compiled with the VC6 or VC9 compiler. For example, if you are running PHP 5.3, you are using non-thread-safe PHP, and your PHP installation was compiled with the VC9 compiler, you should use the php_sqlsrv_53_nts_vc9.dll file. (You should use a non-thread-safe version compiled with the VC9 compiler if you are using IIS as your web server). If you are running PHP 5.2, you are using thread-safe PHP, and your PHP installation was compiled with the VC6 compiler, you should use the php_sqlsrv_52_ts_vc6.dll file.
The drivers can also be used with PDO.

Why don't you use the MySQL built in password hasher:
http://dev.mysql.com/doc/refman/5.1/en/password-hashing.html
mysql> SELECT PASSWORD('mypass');
+-------------------------------------------+
| PASSWORD('mypass') |
+-------------------------------------------+
| *6C8989366EAF75BB670AD8EA7A7FC1176A95CEF4 |
+-------------------------------------------+
for comparison you could something like this:
select id from PassworTable where Userid='<userid>' and Password=PASSWORD('<password>')
and if it returns a value then the user is correct.
(I would assume that folks using containers know what they're doing, but here's my two cents)
Let's say you setup your project using cookiecutter-django and enabled the docker container support, be sure to update the pip requirements file with djangorestframework==<x.yy.z>
(or whichever python dependency you're trying to install) and re-build the docker images (local and production).
Since the other posts say everything (and I stumbled upon this post while looking for the following).
Here is a way how to execute a python script from another python script:
Python 2:
execfile("somefile.py", global_vars, local_vars)
Python 3:
with open("somefile.py") as f:
code = compile(f.read(), "somefile.py", 'exec')
exec(code, global_vars, local_vars)
and you can supply args by providing some other sys.argv
