Here the problem was my Avast AV. As soon I disabled it, the problem was gone.
But, I really would like to understand the cause of this behavior.
Laravel >= 5.3 method lists() is deprecated use pluck()
$items = Items::pluck('name', 'id');
{!! Form::select('items', $items, null, ['class' => 'some_css_class']) !!}
This will give you a select box with same select options as id numbers in DB
for example if you have this in your DB table:
id name
1 item1
2 item2
3 item3
4 item4
in select box it will be like this
<select>
<option value="1">item1</option>
<option value="2">item2</option>
<option value="3">item3</option>
<option value="4">item4</option>
</select>
I found out that pluck now returns a collection, and you need to add ->toArray() at the end of pluck...so like this: pluck('name', 'id')->toArray();
The sample config you provided is actually valid YAML. In fact, YAML meets all of your demands, is implemented in a large number of languages, and is extremely human friendly. I would highly recommend you use it. The PyYAML project provides a nice python module, that implements YAML.
To use the yaml module is extremely simple:
import yaml
config = yaml.safe_load(open("path/to/config.yml"))
My solution was to create a pipelined function. The advantages are that the query can be a single line:
select * from table(yourfunction(param1, param2));
To define the function you would need to do something like the following:
-- Declare the record columns
TYPE your_record IS RECORD(
my_col1 VARCHAR2(50),
my_col2 varchar2(4000)
);
TYPE your_results IS TABLE OF your_record;
-- Declare the function
function yourfunction(a_Param1 varchar2, a_Param2 varchar2)
return your_results pipelined is
rt your_results;
begin
-- Your query to load the table type
select s.col1,s.col2
bulk collect into rt
from your_table s
where lower(s.col1) like lower('%'||a_Param1||'%');
-- Stuff the results into the pipeline..
if rt.count > 0 then
for i in rt.FIRST .. rt.LAST loop
pipe row (rt(i));
end loop;
end if;
-- Add more results as you please....
return;
end find;
And as mentioned above, all you would do to view your results is:
select * from table(yourfunction(param1, param2)) t order by t.my_col1;
Jasypt can do it for you easy and simple
does R stop no matter the N value you use? try to use small values and see if it's the mvrnorm function that is the issue or you could simply loop it on subsets. Insert the gc()
function in the loop to free some RAM continuously
My favorite method uses cv2.copyMakeBorder with no border, like so.
copy = cv2.copyMakeBorder(original,0,0,0,0,cv2.BORDER_REPLICATE)
I did a time test here, using each method 100000 times in a loop. The results surprised me. (The results still surprise me after editing them in response to valid criticism in the comments.)
Here's the script:
import timeit
bad_chars = '(){}<>'
setup = """import re
import string
s = 'Barack (of Washington)'
bad_chars = '(){}<>'
rgx = re.compile('[%s]' % bad_chars)"""
timer = timeit.Timer('o = "".join(c for c in s if c not in bad_chars)', setup=setup)
print "List comprehension: ", timer.timeit(100000)
timer = timeit.Timer("o= rgx.sub('', s)", setup=setup)
print "Regular expression: ", timer.timeit(100000)
timer = timeit.Timer('for c in bad_chars: s = s.replace(c, "")', setup=setup)
print "Replace in loop: ", timer.timeit(100000)
timer = timeit.Timer('s.translate(string.maketrans("", "", ), bad_chars)', setup=setup)
print "string.translate: ", timer.timeit(100000)
Here are the results:
List comprehension: 0.631745100021
Regular expression: 0.155561923981
Replace in loop: 0.235936164856
string.translate: 0.0965719223022
Results on other runs follow a similar pattern. If speed is not the primary concern, however, I still think string.translate
is not the most readable; the other three are more obvious, though slower to varying degrees.
In case you are working with a column with string values, you can use THE VERY USEFUL function series.str.isnumeric() like:
a = pd.Series(['hi','hola','2.31','288','312','1312', '0,21', '0.23'])
What i do is to copy that column to new column, and do a str.replace('.','') and str.replace(',','') then i select the numeric values. and:
a = a.str.replace('.','')
a = a.str.replace(',','')
a.str.isnumeric()
Out[15]: 0 False 1 False 2 True 3 True 4 True 5 True 6 True 7 True dtype: bool

Be aware that the Path
is case sensitive. I tried setx PATH
and it didn't work. In my case it was setx Path
. Make sure your CMD run as Administrator.
setx Path "%PATH%;C:\Program Files\nodejs"
Now just restart your command prompt (or restart the PC) and the node
command should be available.
The Module pattern was originally defined as a way to provide both private and public encapsulation for classes in conventional software engineering.
When working with the Module pattern, we may find it useful to define a simple template that we use for getting started with it. Here's one that covers name-spacing, public and private variables.
In JavaScript, the Module pattern is used to further emulate the concept of classes in such a way that we're able to include both public/private methods and variables inside a single object, thus shielding particular parts from the global scope. What this results in is a reduction in the likelihood of our function names conflicting with other functions defined in additional scripts on the page.
var myNamespace = (function () {
var myPrivateVar, myPrivateMethod;
// A private counter variable
myPrivateVar = 0;
// A private function which logs any arguments
myPrivateMethod = function( foo ) {
console.log( foo );
};
return {
// A public variable
myPublicVar: "foo",
// A public function utilizing privates
myPublicFunction: function( bar ) {
// Increment our private counter
myPrivateVar++;
// Call our private method using bar
myPrivateMethod( bar );
}
};
})();
Advantages
why is the Module pattern a good choice? For starters, it's a lot cleaner for developers coming from an object-oriented background than the idea of true encapsulation, at least from a JavaScript perspective.
Secondly, it supports private data - so, in the Module pattern, public parts of our code are able to touch the private parts, however the outside world is unable to touch the class's private parts.
Disadvantages
The disadvantages of the Module pattern are that as we access both public and private members differently, when we wish to change visibility, we actually have to make changes to each place the member was used.
We also can't access private members in methods that are added to the object at a later point. That said, in many cases the Module pattern is still quite useful and when used correctly, certainly has the potential to improve the structure of our application.
The Revealing Module Pattern
Now that we're a little more familiar with the module pattern, let’s take a look at a slightly improved version - Christian Heilmann’s Revealing Module pattern.
The Revealing Module pattern came about as Heilmann was frustrated with the fact that he had to repeat the name of the main object when we wanted to call one public method from another or access public variables.He also disliked the Module pattern’s requirement for having to switch to object literal notation for the things he wished to make public.
The result of his efforts was an updated pattern where we would simply define all of our functions and variables in the private scope and return an anonymous object with pointers to the private functionality we wished to reveal as public.
An example of how to use the Revealing Module pattern can be found below
var myRevealingModule = (function () {
var privateVar = "Ben Cherry",
publicVar = "Hey there!";
function privateFunction() {
console.log( "Name:" + privateVar );
}
function publicSetName( strName ) {
privateVar = strName;
}
function publicGetName() {
privateFunction();
}
// Reveal public pointers to
// private functions and properties
return {
setName: publicSetName,
greeting: publicVar,
getName: publicGetName
};
})();
myRevealingModule.setName( "Paul Kinlan" );
Advantages
This pattern allows the syntax of our scripts to be more consistent. It also makes it more clear at the end of the module which of our functions and variables may be accessed publicly which eases readability.
Disadvantages
A disadvantage of this pattern is that if a private function refers to a public function, that public function can't be overridden if a patch is necessary. This is because the private function will continue to refer to the private implementation and the pattern doesn't apply to public members, only to functions.
Public object members which refer to private variables are also subject to the no-patch rule notes above.
This will work.
def check(arr):
if np.all(arr == 0):
return True
return False
There is a builtin function all
:
all (x > limit for x in my_list)
Being limit the value greater than which all numbers must be.
Use substring and concatenate:
if(str.length() > 50)
strOut = str.substring(0,7) + "...";
I am not really sure about your question (the meaning of "empty table" etc, or how mappedBy
and JoinColumn
were not working).
I think you were trying to do a bi-directional relationships.
First, you need to decide which side "owns" the relationship. Hibernate is going to setup the relationship base on that side. For example, assume I make the Post
side own the relationship (I am simplifying your example, just to keep things in point), the mapping will look like:
(Wish the syntax is correct. I am writing them just by memory. However the idea should be fine)
public class User{
@OneToMany(fetch=FetchType.LAZY, cascade = CascadeType.ALL, mappedBy="user")
private List<Post> posts;
}
public class Post {
@ManyToOne(fetch=FetchType.LAZY)
@JoinColumn(name="user_id")
private User user;
}
By doing so, the table for Post
will have a column user_id
which store the relationship. Hibernate is getting the relationship by the user
in Post
(Instead of posts
in User
. You will notice the difference if you have Post
's user
but missing User
's posts
).
You have mentioned mappedBy
and JoinColumn
is not working. However, I believe this is in fact the correct way. Please tell if this approach is not working for you, and give us a bit more info on the problem. I believe the problem is due to something else.
Edit:
Just a bit extra information on the use of mappedBy
as it is usually confusing at first. In mappedBy
, we put the "property name" in the opposite side of the bidirectional relationship, not table column name.
I think the following is the best solution:
css:
.edit-button {
background-image: url(edit.png);
background-size: 100%;
background-repeat:no-repeat;
width: 24px;
height: 24px;
}
html:
<input class="edit-button" type="image" src="transparent.png" />
iOS 10 update
The ban on autoplay has been lifted as of iOS 10 - but with some restrictions (e.g. A can be autoplayed if there is no audio track).
To see a full list of these restrictions, see the official docs: https://webkit.org/blog/6784/new-video-policies-for-ios/
iOS 9 and before
As of iOS 6.1, it is no longer possible to auto-play videos on the iPad.
My assumption as to why they've disabled the auto-play feature?
Well, as many device owners have data usage/bandwidth limits on their devices, I think Apple felt that the user themselves should decide when they initiate bandwidth usage.
After a bit of research I found the following extract in the Apple documentation in regard to auto-play on iOS devices to confirm my assumption:
"Apple has made the decision to disable the automatic playing of video on iOS devices, through both script and attribute implementations.
In Safari, on iOS (for all devices, including iPad), where the user may be on a cellular network and be charged per data unit, preload and auto-play are disabled. No data is loaded until the user initiates it." - Apple documentation.
Here is a separate warning featured on the Safari HTML5 Reference page about why embedded media cannot be played in Safari on iOS:
Warning: To prevent unsolicited downloads over cellular networks at the user’s expense, embedded media cannot be played automatically in Safari on iOS—the user always initiates playback. A controller is automatically supplied on iPhone or iPod touch once playback in initiated, but for iPad you must either set the controls attribute or provide a controller using JavaScript.
What this means (in terms of code) is that Javascript's play()
and load()
methods are inactive until the user initiates playback, unless the play()
or load()
method is triggered by user action (e.g. a click event).
Basically, a user-initiated play button works, but
an onLoad="play()"
event does not.
For example, this would play the movie:
<input type="button" value="Play" onclick="document.myMovie.play()">
Whereas the following would do nothing on iOS:
<body onload="document.myMovie.play()">
In all of the cases above, the variable is correctly set, but not correctly read! The right way is to use double quotes when referencing:
echo "$var"
This gives the expected value in all the examples given. Always quote variable references!
Why?
When a variable is unquoted, it will:
Undergo field splitting where the value is split into multiple words on whitespace (by default):
Before: /* Foobar is free software */
After: /*
, Foobar
, is
, free
, software
, */
Each of these words will undergo pathname expansion, where patterns are expanded into matching files:
Before: /*
After: /bin
, /boot
, /dev
, /etc
, /home
, ...
Finally, all the arguments are passed to echo, which writes them out separated by single spaces, giving
/bin /boot /dev /etc /home Foobar is free software Desktop/ Downloads/
instead of the variable's value.
When the variable is quoted it will:
This is why you should always quote all variable references, unless you specifically require word splitting and pathname expansion. Tools like shellcheck are there to help, and will warn about missing quotes in all the cases above.
No. Regular expressions in Python are handled by the re
module.
article = re.sub(r'(?is)</html>.+', '</html>', article)
In general:
text_after = re.sub(regex_search_term, regex_replacement, text_before)
The simplest modification (to the code in your question) is this:
Range("A" & Rows.Count).End(xlUp).Select
Selection.EntireRow.Delete
Which can be simplified to:
Range("A" & Rows.Count).End(xlUp).EntireRow.Delete
If you revise your regular expression like this:
drupal-6.14/(?=sites(?!/all|/default)).*
^^
...then it will match all inputs that contain drupal-6.14/
followed by sites
followed by anything other than /all
or /default
. For example:
drupal-6.14/sites/foo
drupal-6.14/sites/bar
drupal-6.14/sitesfoo42
drupal-6.14/sitesall
Changing ?=
to ?!
to match your original regex simply negates those matches:
drupal-6.14/(?!sites(?!/all|/default)).*
^^
So, this simply means that drupal-6.14/
now cannot be followed by sites
followed by anything other than /all
or /default
. So now, these inputs will satisfy the regex:
drupal-6.14/sites/all
drupal-6.14/sites/default
drupal-6.14/sites/all42
But, what may not be obvious from some of the other answers (and possibly your question) is that your regex will also permit other inputs where drupal-6.14/
is followed by anything other than sites
as well. For example:
drupal-6.14/foo
drupal-6.14/xsites
Conclusion: So, your regex basically says to include all subdirectories of drupal-6.14
except those subdirectories of sites
whose name begins with anything other than all
or default
.
After a lot of search and tests i found the solution : if you are in windows :
1 - first you must found the PG databases directory execute the command as sql command in pgAdmin query tools
$ show data_directory;
result :
------------------------ - D:/PG_DATA/data - ------------------------
2 - go to the bin directory of postgres in my case it's located "c:/programms/postgresSql/bin"
and open a command prompt (CMD) and execute this command :
pg_ctl -D "D:\PSG_SQL\data" restart
This should do it.
I came here looking for making an input that's actually multiple lines. Turns out I didn't want an input, I wanted a textarea. You can set height or line-height as other answers specify, but it'll still just be one line of a textbox. If you want actual multiple lines, use a textarea instead. The following is an example of a 3-row textarea with a width of 500px (should be a good part of the page, not necessary to set this and will have to change it based on your requirements).
<textarea name="roleExplanation" style="width: 500px" rows="3">This role is for facility managers and holds the highest permissions in the application.</textarea>
Try this regex:
^(\+?\d{1,4}[\s-])?(?!0+\s+,?$)\d{10}\s*,?$
Explanation of the regex using Perl's YAPE is as below:
NODE EXPLANATION
----------------------------------------------------------------------
(?-imsx: group, but do not capture (case-sensitive)
(with ^ and $ matching normally) (with . not
matching \n) (matching whitespace and #
normally):
----------------------------------------------------------------------
^ the beginning of the string
----------------------------------------------------------------------
( group and capture to \1 (optional
(matching the most amount possible)):
----------------------------------------------------------------------
\+? '+' (optional (matching the most amount
possible))
----------------------------------------------------------------------
\d{1,4} digits (0-9) (between 1 and 4 times
(matching the most amount possible))
----------------------------------------------------------------------
[\s-] any character of: whitespace (\n, \r,
\t, \f, and " "), '-'
----------------------------------------------------------------------
)? end of \1 (NOTE: because you are using a
quantifier on this capture, only the LAST
repetition of the captured pattern will be
stored in \1)
----------------------------------------------------------------------
(?! look ahead to see if there is not:
----------------------------------------------------------------------
0+ '0' (1 or more times (matching the most

Here's a function I wrote for another answer: Javascript Image Url Verify. I don't know if it's exactly what you need, but it uses the various techniques that you would use which include handlers for onload
, onerror
, onabort
and a general timeout.
Because image loading is asynchronous, you call this function with your image and then it calls your callback sometime later with the result.
Actually it's way easier to use ToolBucket plugin for Notepad++ to multiline replace.
To activate it just go to N++ menu:
Plugins > Plugin Manager > Show Plugin Manager > Check ToolBucket > Install.
Restart N++ and press ALT + SHIFT + F to multiline edit.
In AndroidManifest.xml
, set android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
in application
tag.
Individual activities can override the default by setting their own theme attributes.
It seems if your key is saved in a variable. data.key = value
won't work.
You should use data[key] = value
Example:
data = {key1:'v1', key2:'v2'};
var mykey = 'key1';
data.mykey = 'newv1';
data[mykey] = 'newV2';
console.log(data);
Result:
{
"key1": "newV2",
"key2": "v2",
"mykey": "newv1"
}
Another option using labs
and setting colour to NULL
.
ggplot(df, aes(x, y, colour = g)) +
geom_line(stat = "identity") +
theme(legend.position = "bottom") +
labs(colour = NULL)
I published the vue-unique-id Vue plugin for this on npm.
None of the other solutions address the requirement of having more than one form element in your component. Here's my take on a plugin that builds on previously given answers:
Vue.use((Vue) => {
// Assign a unique id to each component
let uuid = 0;
Vue.mixin({
beforeCreate: function() {
this.uuid = uuid.toString();
uuid += 1;
},
});
// Generate a component-scoped id
Vue.prototype.$id = function(id) {
return "uid-" + this.uuid + "-" + id;
};
});
This doesn't rely on the internal _uid
property which is reserved for internal use.
Use it like this in your component:
<label :for="$id('field1')">Field 1</label>
<input :id="$id('field1')" type="text" />
<label :for="$id('field2')">Field 2</label>
<input :id="$id('field2')" type="text" />
To produce something like this:
<label for="uid-42-field1">Field 1</label>
<input id="uid-42-field1" type="text" />
<label for="uid-42-field2">Field 2</label>
<input id="uid-42-field2" type="text" />
In Linq-to-SQL if you try to get the first element on a query with no results you will get sequence contains no elements
error. I can assure you that the mentioned error is not equal to object reference not set to an instance of an object
.
in conclusion no, it won't return null since null can't say sequence contains no elements
it will always say object reference not set to an instance of an object
;)
You would use the read.csv
function; for example:
dat = read.csv("spam.csv", header = TRUE)
You can also reference this tutorial for more details.
Note: make sure the .csv
file to read is in your working directory (using getwd()
) or specify the right path to file. If you want, you can set the current directory using setwd
.
If the function return Nothing, you can try this below
if (ddlCustomerNumber.Items.FindByText(
GetCustomerNumberCookie().ToString()) != Nothing)
{
...
}
>>> r = re.compile("([a-zA-Z]+)([0-9]+)")
>>> m = r.match("foobar12345")
>>> m.group(1)
'foobar'
>>> m.group(2)
'12345'
So, if you have a list of strings with that format:
import re
r = re.compile("([a-zA-Z]+)([0-9]+)")
strings = ['foofo21', 'bar432', 'foobar12345']
print [r.match(string).groups() for string in strings]
Output:
[('foofo', '21'), ('bar', '432'), ('foobar', '12345')]
This is a security update. If an attacker can modify some file in the web server (the JS one, for example), he can make every loaded pages to download another script (for example to keylog your password or steal your SessionID and send it to his own server).
To avoid it, the browser check the Same-origin policy
Your problem is that the browser is trying to load something with your script (with an Ajax request) that is on another domain (or subdomain). To avoid it (if it is on your own website) you can:
For better browser compatibility you can rely on a regular expression. This will work in all web browsers released in the last 20 years:
String.prototype.equalsci = function(s) {
var regexp = RegExp("^"+this.replace(/[.\\+*?\[\^\]$(){}=!<>|:-]/g, "\\$&")+"$", "i");
return regexp.test(s);
}
"PERSON@Ü.EXAMPLE.COM".equalsci("person@ü.example.com")// returns true
This is different from the other answers found here because it takes into account that not all users are using modern web browsers.
Note: If you need to support unusual cases like the Turkish language you will need to use localeCompare because i and I are not the same letter in Turkish.
"I".localeCompare("i", undefined, { sensitivity:"accent"})===0// returns true
"I".localeCompare("i", "tr", { sensitivity:"accent"})===0// returns false
Yet another weird case that gave me this error. I had erroneously referenced my foreign keys to the id primary key. This was caused by incorrect alter table commands. I found this out by querying the INFORMATION_SCHEMA table (See this stackoverflow answer)
The table was so confused it could not be fixed by any ALTER TABLE commands. I finally dropped the table and reconstructed it. This got rid of the integrityError.
You are single quoting your SQL statement which is making the variables text instead of variables.
$sql = "SELECT *
FROM $usertable
WHERE PartNumber = $partid";
If you're looking for a ruby based solution for this problem, I recommend using the Google Calculator method a solution similar to the following: http://j.mp/QIC564
require 'faraday'
require 'faraday_middleware'
require 'json'
# Debug:
# require "pry"
country_code_src = "USD"
country_code_dst = "INR"
connection = Faraday.get("http://www.google.com/ig/calculator?hl=en&q=1#{country_code_src}=?#{country_code_dst}")
currency_comparison_hash = eval connection.body #Google's output is not JSON, it's a hash
dst_currency_value, *dst_currency_text = *currency_comparison_hash[:rhs].split(' ')
dst_currency_value = dst_currency_value.to_f
dst_currency_text = dst_currency_text.join(' ')
puts "#{country_code_dst} -> #{dst_currency_value} (#{dst_currency_text} to 1 #{country_code_src})"
use ctrl
+ shift
+ f
on windows
Wrap them in {}
:
${"file" . $i} = file($filelist[$i]);
Using ${}
is a way to create dynamic variables, simple example:
${'a' . 'b'} = 'hello there';
echo $ab; // hello there
You can check an example in Plunker over here plunker example filters
filter() {
let storeId = 1;
this.bookFilteredList = this.bookList
.filter((book: Book) => book.storeId === storeId);
this.bookList = this.bookFilteredList;
}
Another way
@Html.TextAreaFor(model => model.Comments[0].Comment)
And in your css do this
textarea
{
font-family: inherit;
width: 650px;
height: 65px;
}
That DataType dealie allows carriage returns in the data, not everybody likes those.
Angular provides a number of built-in directives for manipulating CSS styling conditionally/dynamically:
The normal "Angular way" involves tying a model/scope property to a UI element that will accept user input/manipulation (i.e., use ng-model), and then associating that model property to one of the built-in directives mentioned above.
When the user changes the UI, Angular will automatically update the associated elements on the page.
ng-class accepts an "expression" that must evaluate to one of the following:
Assuming your items are displayed using ng-repeat over some array model, and that when the checkbox for an item is checked you want to apply the pending-delete
class:
<div ng-repeat="item in items" ng-class="{'pending-delete': item.checked}">
... HTML to display the item ...
<input type="checkbox" ng-model="item.checked">
</div>
Above, we used ng-class expression type #3 - a map/object of class names to boolean values.
ng-style accepts an "expression" that must evaluate to:
For a contrived example, suppose the user can type in a color name into a texbox for the background color (a jQuery color picker would be much nicer):
<div class="main-body" ng-style="{color: myColor}">
...
<input type="text" ng-model="myColor" placeholder="enter a color name">
The fiddle also contains an example of ng-show and ng-hide. If a checkbox is checked, in addition to the background-color turning pink, some text is shown. If 'red' is entered in the textbox, a div becomes hidden.
Each of the three conditions is evaluated independently[1]:
id != 1 // false
id != 2 // true
id != 3 // true
Then it evaluates false || true || true
, which is true (a || b
is true if either a
or b
is true). I think you want
id != 1 && id != 2 && id != 3
which is only true if the ID is not 1 AND it's not 2 AND it's not 3.
[1]: This is not strictly true, look up short-circuit evaluation. In reality, only the first two clauses are evaluated because that is all that is necessary to determine the truth value of the expression.
Just use the array of options, to see, which option is currently selected.
$options = array( 'one', 'two', 'three' );
$output = '';
for( $i=0; $i<count($options); $i++ ) {
$output .= '<option '
. ( $_GET['sel'] == $options[$i] ? 'selected="selected"' : '' ) . '>'
. $options[$i]
. '</option>';
}
Sidenote: I would define a value to be some kind of id for each element, else you may run into problems, when two options have the same string representation.
You can use CSS to do it for example
<style>
html{
width:100%;
height:100%;
}
body{
width:100%;
height:100%;
background-color:#DDD;
}
</style>
While LINQ-to-SQL will generate an OFFSET
clause (possibly emulated using ROW_NUMBER() OVER()
as others have mentioned), there is an entirely different, much faster way to perform paging in SQL. This is often called the "seek method" as described in this blog post here.
SELECT TOP 10 first_name, last_name, score
FROM players
WHERE (score < @previousScore)
OR (score = @previousScore AND player_id < @previousPlayerId)
ORDER BY score DESC, player_id DESC
The @previousScore
and @previousPlayerId
values are the respective values of the last record from the previous page. This allows you to fetch the "next" page. If the ORDER BY
direction is ASC
, simply use >
instead.
With the above method, you cannot immediately jump to page 4 without having first fetched the previous 40 records. But often, you do not want to jump that far anyway. Instead, you get a much faster query that might be able to fetch data in constant time, depending on your indexing. Plus, your pages remain "stable", no matter if the underlying data changes (e.g. on page 1, while you're on page 4).
This is the best way to implement paging when lazy loading more data in web applications, for instance.
Note, the "seek method" is also called keyset paging.
You can use below function for relative path as absolute path is not a good idea to add in script
Import
import sys, os
Use code as below :
ROOT_DIR = os.path.dirname(os.path.abspath(__file__))
screenshotpath = os.path.join(os.path.sep, ROOT_DIR,'Screenshots'+ os.sep)
driver.get_screenshot_as_file(screenshotpath+"testPngFunction.png")
make sure you create the folder where the .py file is present.
os.path.join
also prevent you to run your script in cross-platform like: UNIX and windows. It will generate path separator as per OS at runtime. os.sep
is similar like File.separtor
in java
Just append :after
to your #alertlist li:hover
selector the same way you do with your #alertlist li.selected
selector:
#alertlist li.selected:after, #alertlist li:hover:after
{
position:absolute;
top: 0;
right:-10px;
bottom:0;
border-top: 10px solid transparent;
border-bottom: 10px solid transparent;
border-left: 10px solid #303030;
content: "";
}
This will give a list of selected
List<ListItem> items = checkboxlist.Items.Cast<ListItem>().Where(n => n.Selected).ToList();
This will give a list of the selected boxes' values (change Value for Text if that is wanted):
var values = checkboxlist.Items.Cast<ListItem>().Where(n => n.Selected).Select(n => n.Value ).ToList()
CAUTION: commit any work you wish to retain first.
You may reset your workspace (and recover the deleted files)
git checkout ./*
If your input was structured as XML, you could use the importXML
function. (More info here at quirksmode).
If it isn't XML, and there isn't an equivalent function for importing plain text, then you could open it in a hidden iframe and then read the contents from there.
BadImageFormatException
, in my experience, is almost always to do with x86 versus x64 compiled assemblies. It sounds like your C++ assembly is compiled for x86 and you are running on an x64 process. Is that correct?
Instead of using AnyCPU/Mixed
as the platform. Try to manually set it to x86
and see if it will run after that.
Hope this helps.

Andrew's answer is good.
And just to help you out a bit more, here's how you use multiple formatting in one string
"Hello %s, my name is %s" % ('john', 'mike') # Hello john, my name is mike".
If you are using ints instead of string, use %d instead of %s.
"My name is %s and i'm %d" % ('john', 12) #My name is john and i'm 12
I can confirm that mp4 just will not work in the video tag. No matter how much you try to mess with the type tag and the codec and the mime types from the server.
Crazy, because for the same exact video, on the same test page, the old embed tag for an mp4 works just fine in firefox. I spent all yesterday messing with this. Firefox is like IE all of a sudden, hours and hours of time, not billable. Yay.
Speaking of IE, it fails FAR MORE gracefully on this. When it can't match up the format it falls to the content between the tags, so it is possible to just put video around object around embed and everything works great. Firefox, nope, despite failing, it puts up the poster image (greyed out so that isn't even useful as a fallback) with an error message smack in the middle. So now the options are put in browser recognition code (meaning we've gained nothing on embedding videos in the last ten years) or ditch html5.
I ran into the need to allow decimal values, so I used not Value like '%[^0-9.]%'
If you're working on the CLI and only have one flask app/process running (or rather, you just want want to kill any flask process running on your system), you can kill it with:
kill $(pgrep -f flask)
//
is unconditionally "flooring division", e.g:
>>> 4.0//1.5
2.0
As you see, even though both operands are float
s, //
still floors -- so you always know securely what it's going to do.
Single /
may or may not floor depending on Python release, future imports, and even flags on which Python's run, e.g.:
$ python2.6 -Qold -c 'print 2/3'
0
$ python2.6 -Qnew -c 'print 2/3'
0.666666666667
As you see, single /
may floor, or it may return a float, based on completely non-local issues, up to and including the value of the -Q
flag...;-).
So, if and when you know you want flooring, always use //
, which guarantees it. If and when you know you don't want flooring, slap a float()
around other operand and use /
. Any other combination, and you're at the mercy of version, imports, and flags!-)
My case was a little different. After restarting my system, I had not whitelisted my IP address on Mongo while doing local development.
Select Network Access > Add IP Address > Add your current IP Address
You select data like this:
$db = new PDO("...");
$statement = $db->prepare("select id from some_table where name = :name");
$statement->execute(array(':name' => "Jimbo"));
$row = $statement->fetch(); // Use fetchAll() if you want all results, or just iterate over the statement, since it implements Iterator
You insert in the same way:
$statement = $db->prepare("insert into some_other_table (some_id) values (:some_id)");
$statement->execute(array(':some_id' => $row['id']));
I recommend that you configure PDO to throw exceptions upon error. You would then get a PDOException
if any of the queries fail - No need to check explicitly. To turn on exceptions, call this just after you've created the $db
object:
$db = new PDO("...");
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

I'm wondering if this code would create an effective generic array?
public T [] createArray(int desiredSize){
ArrayList<T> builder = new ArrayList<T>();
for(int x=0;x<desiredSize;x++){
builder.add(null);
}
return builder.toArray(zeroArray());
}
//zeroArray should, in theory, create a zero-sized array of T
//when it is not given any parameters.
private T [] zeroArray(T... i){
return i;
}
Edit: Perhaps an alternate way of creating such an array, if the size you required was known and small, would be to simply feed the required number of "null"s into the zeroArray command?
Though obviously this isn't as versatile as using the createArray code.

There are several ways to do this:
You can use the InStr
build-in function to test if a String contains a substring. InStr
will either return the index of the first match, or 0. So you can test if a String begins with a substring by doing the following:
If InStr(1, "Hello World", "Hello W") = 1 Then
MsgBox "Yep, this string begins with Hello W!"
End If
If InStr
returns 1
, then the String ("Hello World"), begins with the substring ("Hello W").
You can also use the like
comparison operator along with some basic pattern matching:
If "Hello World" Like "Hello W*" Then
MsgBox "Yep, this string begins with Hello W!"
End If
In this, we use an asterisk (*) to test if the String begins with our substring.
In my case I did something like this, based on Luis's answer:
...State object...
userInfo = {
name: '...',
...
}
...Reducer's code...
case CHANGED_INFO:
return {
...state,
userInfo: {
...state.userInfo,
// I'm sending the arguments like this: changeInfo({ id: e.target.id, value: e.target.value }) and use them as below in reducer!
[action.data.id]: action.data.value,
},
};
You can perform your housekeeping in a separate script which can be cronned to run daily. Something like this:
find /path/to/logs -type f -mtime +7 -exec rm -f {} \;
There are a couple of variants of a rename command, in your case, it may be as simple as
rename ABC XYZ *.dat
You may have a version which takes a Perl regex;
rename 's/ABC/XYZ/' *.dat
Once you have started tomcat simply run the following command at a terminal prompt:
ps -ef | grep tomcat
This will show the process details and indicate which JVM (by folder location) is running tomcat.
Perhaps you're asking about keeping such things going...
Of course you'll invoke a full table scan for the queries and if the table containing the scores that need to be tallied (aggregations) is large you might want a better performing solution, you can create a secondary table and use rules, such as on insert
- you might look into it.
Not all RDBMS engines have rules, though!
Another different way to achieve the renaming or change the mappings for an index is to reindex using logstash. Here is a sample of the logstash 2.1 configuration:
input {
elasticsearch {
hosts => ["es01.example.com", "es02.example.com"]
index => "old-index-name"
size => 500
scroll => "5m"
}
}
filter {
mutate {
remove_field => [ "@version" ]
}
date {
"match" => [ "custom_timestamp", "MM/dd/YYYY HH:mm:ss" ]
target => "@timestamp"
}
}
output {
elasticsearch {
hosts => ["es01.example.com", "es02.example.com" ]
manage_template => false
index => "new-index-name"
}
}
There is an important detail:
set PATH="C:\linutils;C:\wingit\bin;%PATH%"
does not work, while
set PATH=C:\linutils;C:\wingit\bin;%PATH%
works. The difference is the quotes!
UPD also see the comment by venimus
It's the correct way to access linked DB:
EXEC [ServerName].[DatabaseName].dbo.sp_HelpText 'storedProcName'
But make sure to mention dbo
as it owns the sp_helptext
.
Function overloading or method overloading is the ability to create multiple functions of the same name with different implementations (Wikipedia)
This feature is not possible in JS - the last defined function is taken in case of multiple declarations:
function foo(a1, a2) { return `${a1}, ${a2}` }
function foo(a1) { return `${a1}` } // replaces above `foo` declaration
foo(42, "foo") // "42"
Overloads are a compile-time construct with no impact on the JS runtime:
function foo(s: string): string // overload #1 of foo
function foo(s: string, n: number): number // overload #2 of foo
function foo(s: string, n?: number): string | number {/* ... */} // foo implementation
A duplicate implementation error is triggered, if you use above code (safer than JS). TS chooses the first fitting overload in top-down order, so overloads are sorted from most specific to most broad.
Overloaded class method types can be used in a similar way to function overloading:
class LayerFactory {
createFeatureLayer(a1: string, a2: number): string
createFeatureLayer(a1: number, a2: boolean, a3: string): number
createFeatureLayer(a1: string | number, a2: number | boolean, a3?: string)
: number | string { /*... your implementation*/ }
}
const fact = new LayerFactory()
fact.createFeatureLayer("foo", 42) // string
fact.createFeatureLayer(3, true, "bar") // number
The vastly different overloads are possible, as the function implementation is compatible to all overload signatures - enforced by the compiler.
More infos:
I think that you need to look at this -- it should have everything you want.
EDIT: If you don't want to look at the link -- this pretty much sums up what you'd like.
MediaPlayer mp = MediaPlayer.create(context, R.raw.sound_file_1); mp.start();
But I still recommend reading the information at the link.
I don't think other answers explained the key part: why "COUNT(*)" returns more than one result?
I just encountered the same issue today, and what I found out is that if you have another class extending the target mapped class (here "CustomerData"), Hibernate will do this magic.
Hope this will save some time for other unfortunate guys.
Use your own HTTPS-to-HTTP reverse proxy.
If your use case is about a few, rarely changing URLs to embed into the iframe
, you can simply set up a reverse proxy for this on your own server and configure it so that one https
URL on your server maps to one http
URL on the proxied server. Since a reverse proxy is fully serverside, the browser cannot discover that it is "only" talking to a proxy of the real website, and thus will not complain as the connection to the proxy uses SSL properly.
If for example you use Apache2 as your webserver, then see these instructions to create a reverse proxy.
Here is what worked for me. I am using looped-back node module with Electron Js and faced this issue. After trying many things following worked for me.
In your package.json file in the scripts add following lines:
...
"scripts": {
"start": "electron .",
"rebuild": "electron-rebuild"
},
...
And then run following command npm run rebuild
RemoteEndPoint is a property, its type is System.Net.EndPoint which inherits from System.Net.IPEndPoint.
If you take a look at IPEndPoint's members, you'll see that there's an Address
property.
You can do by using reflection:
public void AddFruit<T>()where T: BaseFruit
{
ConstructorInfo constructor = typeof(T).GetConstructor(new Type[] { typeof(int) });
if (constructor == null)
{
throw new InvalidOperationException("Type " + typeof(T).Name + " does not contain an appropriate constructor");
}
BaseFruit fruit = constructor.Invoke(new object[] { (int)150 }) as BaseFruit;
fruit.Enlist(fruitManager);
}
EDIT: Added constructor == null check.
EDIT: A faster variant using a cache:
public void AddFruit<T>()where T: BaseFruit
{
var constructor = FruitCompany<T>.constructor;
if (constructor == null)
{
throw new InvalidOperationException("Type " + typeof(T).Name + " does not contain an appropriate constructor");
}
var fruit = constructor.Invoke(new object[] { (int)150 }) as BaseFruit;
fruit.Enlist(fruitManager);
}
private static class FruitCompany<T>
{
public static readonly ConstructorInfo constructor = typeof(T).GetConstructor(new Type[] { typeof(int) });
}
Change $_POST to $_FILES and make sure your enctype is "multipart/form-data"
Is your input field actually in a form?
<form method="POST" action="update.php">
<input type="hidden" name="filename" value="test" />
</form>
cat filename | grep -v "pattern" > filename.1
mv filename.1 filename
You could also use the following methods but be aware of their internal implementation and/or return values.
1A isNaN(+'13761123123123'); // returns true
1B isNaN(+'13761123123ABC'); // returns false
2A ~~'1.23'; // returns 1
2B ~~'1.2A'; // returns 0
For 1A & 1B the string is first type coerced using the +
operator before being passed to the isNaN()
function. This works because a number types that include non-numeric values return NaN
. There are considerations with the isNaN()'s
implementation details which is documented here. One consideration is if a boolean value is passed as isNaN(+false|true)
are coerced to their numeric equivalents and thus false
is returned but one might expect the function to return true
since the boolean value isn't numeric in the sense of what we are testing.
For 2A & 2B it's worth noting that finding the complement of the number requires the given value in question to be within the range the values of a signed 32 bit integer which can be referenced in the spec.
My personal preference, although it could be argued to be less readable since they include the unary operator, is 1A & 1B because of the speed and conciseness.
Expanding on brettdj's answer, in order to parse disjoint embedded digits into separate numbers:
Sub TestNumList()
Dim NumList As Variant 'Array
NumList = GetNums("34d1fgd43g1 dg5d999gdg2076")
Dim i As Integer
For i = LBound(NumList) To UBound(NumList)
MsgBox i + 1 & ": " & NumList(i)
Next i
End Sub
Function GetNums(ByVal strIn As String) As Variant 'Array of numeric strings
Dim RegExpObj As Object
Dim NumStr As String
Set RegExpObj = CreateObject("vbscript.regexp")
With RegExpObj
.Global = True
.Pattern = "[^\d]+"
NumStr = .Replace(strIn, " ")
End With
GetNums = Split(Trim(NumStr), " ")
End Function
In python 3 urllib2 was merged into urllib. See also another Stack Overflow question and the urllib PEP 3108.

Easiest way to set permissions to 777 is to connect to Your server through FTP Application like FileZilla, right click on folder, module_installation, and click Change Permissions - then write 777 or check all permissions.
You can also use JS if needed
var winHeight = window.innerHeight ||
document.documentElement.clientHeight ||
document.body.clientHeight;
var pageHeight = $('body').height();
if (pageHeight < winHeight) {
$('.main-content,').css('min-height',winHeight)
}
1 You can use string.Replace
method
var sample = "testtesttesttest#replace#testtesttest";
var result = sample.Replace("#replace#", yourValue);
2 You can also use string.Format
var result = string.Format("your right part {0} Your left Part", yourValue);
3 You can use Regex class
On Android 4.4.4, it seems the only way I could stop an alpha fading animation on a View was calling View.animate().cancel()
(i.e., calling .cancel()
on the View's ViewPropertyAnimator
).
Here's the code I'm using for compatibility before and after ICS:
public void stopAnimation(View v) {
v.clearAnimation();
if (canCancelAnimation()) {
v.animate().cancel();
}
}
... with the method:
/**
* Returns true if the API level supports canceling existing animations via the
* ViewPropertyAnimator, and false if it does not
* @return true if the API level supports canceling existing animations via the
* ViewPropertyAnimator, and false if it does not
*/
public static boolean canCancelAnimation() {
return Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH;
}
Here's the animation that I'm stopping:
v.setAlpha(0f);
v.setVisibility(View.VISIBLE);
// Animate the content view to 100% opacity, and clear any animation listener set on the view.
v.animate()
.alpha(1f)
.setDuration(animationDuration)
.setListener(null);
Two solutions: You have to instal the required buildToolVersion or set it as described above.
Notice that if you are trying to set the buildToolsVersion "23.0.3"
using Android Studio 3.0 or more it won't work until you remove all builversion you have keeping just one last version you use.
I read this somewhere else and this works for me.
Hope this helps.
Java is a server side language, whereas javascript is a client side language. Both cannot communicate. If you have setup some server side script using Java you could use AJAX on the client in order to send an asynchronous request to it and thus invoke any possible Java functions. For example if you use jQuery as js framework you may take a look at the $.ajax()
method. Or if you wanted to do it using plain javascript, here's a tutorial.
The scalar formatter supports collecting the exponents. The docs are as follows:
class matplotlib.ticker.ScalarFormatter(useOffset=True, useMathText=False, useLocale=None) Bases: matplotlib.ticker.Formatter
Tick location is a plain old number. If useOffset==True and the data range is much smaller than the data average, then an offset will be determined such that the tick labels are meaningful. Scientific notation is used for data < 10^-n or data >= 10^m, where n and m are the power limits set using set_powerlimits((n,m)). The defaults for these are controlled by the axes.formatter.limits rc parameter.
your technique would be:
from matplotlib.ticker import ScalarFormatter
xfmt = ScalarFormatter()
xfmt.set_powerlimits((-3,3)) # Or whatever your limits are . . .
{{ Make your plot }}
gca().xaxis.set_major_formatter(xfmt)
To get the exponent displayed in the format x10^5
, instantiate the ScalarFormatter with useMathText=True
.
You could also use:
xfmt.set_useOffset(10000)
To get a result like this:
No, it's not possible. Not without the export
keyword, which for all intents and purposes doesn't really exist.
The best you can do is put your function implementations in a ".tcc" or ".tpp" file, and #include the .tcc file at the end of your .hpp file. However this is merely cosmetic; it's still the same as implementing everything in header files. This is simply the price you pay for using templates.
That's called onload. DOM ready was actually created for the exact reason that onload waited on images. ( Answer taken from Matchu on a simmilar question a while ago. )
window.onload = function () { alert("It's loaded!") }
onload waits for all resources that are part of the document.

A string in different languages including C sharp and PHP is also considered an array of characters.
Knowing that in theory array operations should be faster than string ones you could do,
$foo = "bar";
$lastChar = strlen($foo) -1;
echo $foo[$lastChar];
$firstChar = 0;
echo $foo[$firstChar];
However, standard array functions like
count();
will not work on a string.
You can use the function connect_ex. It doesn't throw an exception. Instead of that, returns a C style integer value (referred to as errno in C):
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
result = s.connect_ex((host, port))
s.close()
if result:
print "problem with socket!"
else:
print "everything it's ok!"
You can use JPQL as well as JPA Criteria API for any kind of DTO projection(Mapping only selected columns to a DTO class) . Look at below code snippets showing how to selectively select various columns instead of selecting all columns . These example also show how to select various columns from joining multiple columns . I hope this helps .
JPQL code :
String dtoProjection = "new com.katariasoft.technologies.jpaHibernate.college.data.dto.InstructorDto"
+ "(i.id, i.name, i.fatherName, i.address, id.proofNo, "
+ " v.vehicleNumber, v.vechicleType, s.name, s.fatherName, "
+ " si.name, sv.vehicleNumber , svd.name) ";
List<InstructorDto> instructors = queryExecutor.fetchListForJpqlQuery(
"select " + dtoProjection + " from Instructor i " + " join i.idProof id " + " join i.vehicles v "
+ " join i.students s " + " join s.instructors si " + " join s.vehicles sv "
+ " join sv.documents svd " + " where i.id > :id and svd.name in (:names) "
+ " order by i.id , id.proofNo , v.vehicleNumber , si.name , sv.vehicleNumber , svd.name ",
CollectionUtils.mapOf("id", 2, "names", Arrays.asList("1", "2")), InstructorDto.class);
if (Objects.nonNull(instructors))
instructors.forEach(i -> i.setName("Latest Update"));
DataPrinters.listDataPrinter.accept(instructors);
JPA Criteria API code :
@Test
public void fetchFullDataWithCriteria() {
CriteriaBuilder cb = criteriaUtils.criteriaBuilder();
CriteriaQuery<InstructorDto> cq = cb.createQuery(InstructorDto.class);

I feel compelled to provide a counterpoint to Ashwini Chaudhary's answer. Despite appearances, the two-argument form of the round
function does not round a Python float to a given number of decimal places, and it's often not the solution you want, even when you think it is. Let me explain...
The ability to round a (Python) float to some number of decimal places is something that's frequently requested, but turns out to be rarely what's actually needed. The beguilingly simple answer round(x, number_of_places)
is something of an attractive nuisance: it looks as though it does what you want, but thanks to the fact that Python floats are stored internally in binary, it's doing something rather subtler. Consider the following example:
>>> round(52.15, 1)
52.1
With a naive understanding of what round
does, this looks wrong: surely it should be rounding up to 52.2
rather than down to 52.1
? To understand why such behaviours can't be relied upon, you need to appreciate that while this looks like a simple decimal-to-decimal operation, it's far from simple.
So here's what's really happening in the example above. (deep breath) We're displaying a decimal representation of the nearest binary floating-point number to the nearest n
-digits-after-the-point decimal number to a binary floating-point approximation of a numeric literal written in decimal. So to get from the original numeric literal to the displayed output, the underlying machinery has made four separate conversions between binary and decimal formats, two in each direction. Breaking it down (and with the usual disclaimers about assuming IEEE 754 binary64 format, round-ties-to-even rounding, and IEEE 754 rules):
First the numeric literal 52.15
gets parsed and converted to a Python float. The actual number stored is 7339460017730355 * 2**-47
, or 52.14999999999999857891452847979962825775146484375
.
Internally as the first step of the round
operation, Python computes the closest 1-digit-after-the-point decimal string to the stored number. Since that stored number is a touch under the original value of 52.15
, we end up rounding down and getting a string 52.1
. This explains why we're getting 52.1
as the final output instead of 52.2
.
Then in the second step of the round
operation, Python turns that string back into a float, getting the closest binary floating-point number to 52.1
, which is now 7332423143312589 * 2**-47
, or 52.10000000000000142108547152020037174224853515625
.
Finally, as part of Python's read-eval-print loop (REPL), the floating-point value is displayed (in decimal). That involves converting the binary value back to a decimal string, getting 52.1
as the final output.
In Python 2.7 and later, we have the pleasant situation that the two conversions in step 3 and 4 cancel each other out. That's due to Python's choice of repr
implementation, which produces the shortest decimal value guaranteed to round correctly to the actual float. One consequence of that choice is that if you start with any (not too large, not too small) decimal literal with 15 or fewer significant digits then the corresponding float will be displayed showing those exact same digits:
>>> x = 15.34509809234
>>> x
15.34509809234
Unfortunately, this furthers the illusion that Python is storing values in decimal. Not so in Python 2.6, though! Here's the original example executed in Python 2.6:
>>> round(52.15, 1)
52.200000000000003
Not only do we round in the opposite direction, getting 52.2
instead of 52.1
, but the displayed value doesn't even print as 52.2
! This behaviour has caused numerous reports to the Python bug tracker along the lines of "round is broken!". But it's not round
that's broken, it's user expectations. (Okay, okay, round
is a little bit broken in Python 2.6, in that it doesn't use correct rounding.)
Short version: if you're using two-argument round, and you're expecting predictable behaviour from a binary approximation to a decimal round of a binary approximation to a decimal halfway case, you're asking for trouble.
So enough with the "two-argument round is bad" argument. What should you be using instead? There are a few possibilities, depending on what you're trying to do.
If you're rounding for display purposes, then you don't want a float result at all; you want a string. In that case the answer is to use string formatting:
>>> format(66.66666666666, '.4f')
'66.6667'
>>> format(1.29578293, '.6f')
'1.295783'
Even then, one has to be aware of the internal binary representation in order not to be surprised by the behaviour of apparent decimal halfway cases.
>>> format(52.15, '.1f')
'52.1'
If you're operating in a context where it matters which direction decimal halfway cases are rounded (for example, in some financial contexts), you might want to represent your numbers using the Decimal
type. Doing a decimal round on the Decimal
type makes a lot more sense than on a binary type (equally, rounding to a fixed number of binary places makes perfect sense on a binary type). Moreover, the decimal
module gives you better control of the rounding mode. In Python 3, round
does the job directly. In Python 2, you need the quantize
method.
>>> Decimal('66.66666666666').quantize(Decimal('1e-4'))
Decimal('66.6667')
>>> Decimal('1.29578293').quantize(Decimal('1e-6'))
Decimal('1.295783')
In rare cases, the two-argument version of round
really is what you want: perhaps you're binning floats into bins of size 0.01
, and you don't particularly care which way border cases go. However, these cases are rare, and it's difficult to justify the existence of the two-argument version of the round
builtin based on those cases alone.
Adding overflow:auto

Have the same Setup as OP. One controller with many actions... less "messy" :-)
In my case i forgot the "[HttpGet]" when adding a new action.

As everybody says, bash doesn't have a proper language-supported try/catch syntax. You can launch bash with the -e
argument or use set -e
inside the script to abort the entire bash process if any command has a non-zero exit code. (You can also set +e
to temporarily allow failing commands.)
So, one technique to simulate a try/catch block is to launch a sub-process to do the work with -e
enabled. Then in the main process, check the return code of the sub-process.
Bash supports heredoc strings, so you don't have to write two separate files to handle this. In the below example, the TRY heredoc will run in a separate bash instance, with -e
enabled, so the sub-process will crash if any command returns a non-zero exit code. Then, back in the main process, we can check the return code to handle a catch block.
#!/bin/bash
set +e
bash -e <<TRY
echo hello
cd /does/not/exist
echo world
TRY
if [ $? -ne 0 ]; then
echo caught exception
fi
It's not a proper language-supported try/catch block, but it may scratch a similar itch for you.

Putting that in your .profile will dynamically take care of your $JAVA_HOME
export JAVA_HOME=$(/usr/libexec/java_home)
Close your shell afterwards, open a new one and test with
echo $JAVA_HOME
It should display something like
/Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Home
If not, remove any other assignments of JAVA_HOME in your startup scripts. Remember, that these startup scripts start with a .
so they are hidden and won't be included when using *
wildcard, e.g. if you want to grep all files of your home directory, you need to:
grep -s JAVA_HOME ~/.* --exclude=.bash_history
The query you want to show as an example is:
SELECT * FROM temp WHERE mydate > '2009-06-29 16:00:44';
04:00:00 is 4AM, so all the results you're displaying come after that, which is correct.
If you want to show everything after 4PM, you need to use the correct (24hr) notation in your query.
To make things a bit clearer, try this:
SELECT mydate, DATE_FORMAT(mydate, '%r') FROM temp;
That will show you the date, and its 12hr time.
Python 3.5+ introduces %-interpolation (printf
-style formatting) for bytes:
>>> b'%d\r\n' % 3
b'3\r\n'
See PEP 0461 -- Adding % formatting to bytes and bytearray.
On earlier versions, you could use str
and .encode('ascii')
the result:
>>> s = '%d\r\n' % 3
>>> s.encode('ascii')
b'3\r\n'
Note: It is different from what int.to_bytes
produces:
>>> n = 3
>>> n.to_bytes((n.bit_length() + 7) // 8, 'big') or b'\0'
b'\x03'
>>> b'3' == b'\x33' != '\x03'

Yes, you can use filter if you know at which position in the tuple the desired column resides. If the case is that the id is the first element of the tuple then you can filter the list like so:
filter(lambda t: t[0]==10, mylist)
This will return the list of corresponding tuples. If you want the age, just pick the element you want. Instead of filter you could also use list comprehension and pick the element in the first go. You could even unpack it right away (if there is only one result):
[age] = [t[1] for t in mylist if t[0]==10]
But I would strongly recommend to use dictionaries or named tuples for this purpose.

Short Answer
Your i
will be converted to an unsigned integer by adding UINT_MAX + 1
, then the addition will be carried out with the unsigned values, resulting in a large result
(depending on the values of u
and i
).
Long Answer
According to the C99 Standard:
6.3.1.8 Usual arithmetic conversions
- If both operands have the same type, then no further conversion is needed.
- Otherwise, if both operands have signed integer types or both have unsigned integer types, the operand with the type of lesser integer conversion rank is converted to the type of the operand with greater rank.
- Otherwise, if the operand that has unsigned integer type has rank greater or equal to the rank of the type of the other operand, then the operand with signed integer type is converted to the type of the operand with unsigned integer type.
- Otherwise, if the type of the operand with signed integer type can represent all of the values of the type of the operand with unsigned integer type, then the operand with unsigned integer type is converted to the type of the operand with signed integer type.
- Otherwise, both operands are converted to the unsigned integer type corresponding to the type of the operand with signed integer type.
In your case, we have one unsigned int (u
) and signed int (i
). Referring to (3) above, since both operands have the same rank, your i
will need to be converted to an unsigned integer.
6.3.1.3 Signed and unsigned integers
- When a value with integer type is converted to another integer type other than _Bool, if the value can be represented by the new type, it is unchanged.
- Otherwise, if the new type is unsigned, the value is converted by repeatedly adding or subtracting one more than the maximum value that can be represented in the new type until the value is in the range of the new type.
- Otherwise, the new type is signed and the value cannot be represented in it; either the result is implementation-defined or an implementation-defined signal is raised.
Now we need to refer to (2) above. Your i
will be converted to an unsigned value by adding UINT_MAX + 1
. So the result will depend on how UINT_MAX
is defined on your implementation. It will be large, but it will not overflow, because:
6.2.5 (9)
A computation involving unsigned operands can never overflow, because a result that cannot be represented by the resulting unsigned integer type is reduced modulo the number that is one greater than the largest value that can be represented by the resulting type.
Bonus: Arithmetic Conversion Semi-WTF
#include <stdio.h>
int main(void)
{
unsigned int plus_one = 1;
int minus_one = -1;
if(plus_one < minus_one)
printf("1 < -1");
else
printf("boring");
return 0;
}
You can use this link to try this online: https://repl.it/repls/QuickWhimsicalBytes
Bonus: Arithmetic Conversion Side Effect
Arithmetic conversion rules can be used to get the value of UINT_MAX
by initializing an unsigned value to -1
, ie:
unsigned int umax = -1; // umax set to UINT_MAX
This is guaranteed to be portable regardless of the signed number representation of the system because of the conversion rules described above. See this SO question for more information: Is it safe to use -1 to set all bits to true?

I came here and followed above answer. But mismatch in the Order of data type caused an error. The below description from another answer will come handy.
Are the results above the same as the sequence of columns in your table? because oracle is strict in column orders. this example below produces an error:
create table test1_1790 (
col_a varchar2(30),
col_b number,
col_c date);
create table test2_1790 (
col_a varchar2(30),
col_c date,
col_b number);
select * from test1_1790
union all
select * from test2_1790;
ORA-01790: expression must have same datatype as corresponding expression
As you see the root cause of the error is in the mismatching column ordering that is implied by the use of * as column list specifier. This type of errors can be easily avoided by entering the column list explicitly:
select col_a, col_b, col_c from test1_1790 union all select col_a, col_b, col_c from test2_1790; A more frequent scenario for this error is when you inadvertently swap (or shift) two or more columns in the SELECT list:
select col_a, col_b, col_c from test1_1790
union all
select col_a, col_c, col_b from test2_1790;
OR if the above does not solve your problem, how about creating an ALIAS in the columns like this: (the query is not the same as yours but the point here is how to add alias in the column.)
SELECT id_table_a,
desc_table_a,
table_b.id_user as iUserID,
table_c.field as iField
UNION
SELECT id_table_a,
desc_table_a,
table_c.id_user as iUserID,
table_c.field as iField
To get an actual working example going that returns what one would expect:
var startdate = "20.03.2014";
var new_date = moment(startdate, "DD.MM.YYYY");
var thing = new_date.add(5, 'days').format('DD/MM/YYYY');
window.console.log(thing)
I think this would perfectly work :
([1-9][0-9]*(\.[0-9]*[1-9])?|0\.[0-9]*[1-9])
Valid:
1
1.2
1.02
0.1
0.02
Not valid :
0
01
01.2
1.10
For the things that you are suggesting you can just change the levels using the levels
:
levels(iris$Species)[3] <- 'new'
assuming that string1 is your whole operation
use mdas
double result;
string recurAndCheck(string operation){
if(operation.indexOf("/")){
String leftSide = recurAndCheck(operation.split("/")[0]);
string rightSide = recurAndCheck(operation.split("/")[1]);
result = Double.parseDouble(leftSide)/Double.parseDouble(rightSide);
} else if (..continue w/ *...) {
//same as above but change / with *
} else if (..continue w/ -) {
//change as above but change with -
} else if (..continuew with +) {
//change with add
} else {
return;
}
}
Alternatively to a redirect, if it is calling your own code, you could use this:
actionContext.Result = new RedirectToRouteResult(
new RouteValueDictionary(new { controller = "Home", action = "Error" })
);
actionContext.Result.ExecuteResult(actionContext.Controller.ControllerContext);
It is not a pure redirect but gives a similar result without unnecessary overhead.
I think that this will do the trick:
table{
table-layout: fixed;
width: 300px;
}
Install nvm using the following commands in the same order.nvm stands for node version manager.
sudo apt-get update
sudo apt-get install build-essential checkinstall libssl-dev
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.32.1/install.sh | bash
In case the above command does not work add -k after -o- .It should be as below:
curl -o- -k https://raw.githubusercontent.com/creationix/nvm/v0.32.1/install.sh | bash
Then nvm ls-remote
to see the available versions.
In case you get N/A in return,run the following.
export NVM_NODEJS_ORG_MIRROR=http://nodejs.org/dist
alternatively you can run the following commands too
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion
Then nvm install #.#.#
replacing # by version(say nvm 8.9.4)
finally nvm use #.#.#
You have to put the path to the file. For example:
require_once('../web/a.php');
You cannot get the file to require it from internet (with http protocol) it's restricted. The files must be on the same server. With Possibility to see each others (rights)
Dir-1 -
> Folder-1 -> a.php
Dir-2 -
> Folder-2 -> b.php
To include a.php inside b.php => require_once('../../Dir-1/Folder-1/a.php');
To include b.php inside a.php => require_once('../../Dir-2/Folder-2/b.php');
You will need to prevent default form behaviour on submit. After that you will need to submit form programmatically in case of Ok button is selected.
Here is how it could look like:
document.querySelector('#from1').addEventListener('submit', function(e) {
var form = this;
e.preventDefault(); // <--- prevent form from submitting
swal({
title: "Are you sure?",
text: "You will not be able to recover this imaginary file!",
icon: "warning",
buttons: [
'No, cancel it!',
'Yes, I am sure!'
],
dangerMode: true,
}).then(function(isConfirm) {
if (isConfirm) {
swal({
title: 'Shortlisted!',
text: 'Candidates are successfully shortlisted!',
icon: 'success'
}).then(function() {
form.submit(); // <--- submit form programmatically
});
} else {
swal("Cancelled", "Your imaginary file is safe :)", "error");
}
})
});

Thanx @krd, I am using your error catch process, but had to update the print and except statements. I am using Python 2.7.6 on Linux Mint 17.2.
Also, it was unclear where the output string was coming from. My update:
import subprocess
# Output returned in error handler
try:
print("Ping stdout output on success:\n" +
subprocess.check_output(["ping", "-c", "2", "-w", "2", "1.1.1.1"]))
except subprocess.CalledProcessError as e:
print("Ping stdout output on error:\n" + e.output)
# Output returned normally
try:
print("Ping stdout output on success:\n" +
subprocess.check_output(["ping", "-c", "2", "-w", "2", "8.8.8.8"]))
except subprocess.CalledProcessError as e:
print("Ping stdout output on error:\n" + e.output)
I see an output like this:

You can't specify inline styles for pseudo-elements.
This is because pseudo-elements, like pseudo-classes (see my answer to this other question), are defined in CSS using selectors as abstractions of the document tree that can't be expressed in HTML. An inline style
attribute, on the other hand, is specified within HTML for a particular element.
Since inline styles can only occur in HTML, they will only apply to the HTML element that they're defined on, and not to any pseudo-elements it generates.
As an aside, the main difference between pseudo-elements and pseudo-classes in this aspect is that properties that are inherited by default will be inherited by :before
and :after
from the generating element, whereas pseudo-class styles just don't apply at all. In your case, for example, if you place text-align: justify
in an inline style attribute for a td
element, it will be inherited by td:after
. The caveat is that you can't declare td:after
with the inline style attribute; you must do it in the stylesheet.
1 is most readable not compatible with all compilers.
No ISO C compiler has a built in type called bool
. ISO C99 compilers have a type _Bool
, and a header which typedef's bool
. So compatability is simply a case of providing your own header if the compiler is not C99 compliant (VC++ for example).
Of course a simpler approach is to compile your C code as C++.
Add keyword static
to class declaration:
// this is a non-generic static class
public static class LinqHelper
{
}
Use a secure URL for your initial connection, i.e. instead of "http://" use "https://". If the WebSocket transport is chosen, then Socket.IO should automatically use "wss://" (SSL) for the WebSocket connection too.
Update:
You can also try creating the connection using the 'secure' option:
var socket = io.connect('https://localhost', {secure: true});
Use this
openssl ciphers -v | awk '{print $2}' | sort | uniq
Just in case if the problem is still there,
You can refer to ansible inventory through ‘hostvars’
, ‘group_names’
, and ‘groups’
ansible variables.
Example:
To be able to get ip addresses of all servers within group "mygroup", use the below construction:
- debug: msg="{{ hostvars[item]['ansible_eth0']['ipv4']['address'] }}"
with_items:
- "{{ groups['mygroup'] }}"
Sorry for joining too late to the party. Here's an easy solution.
#building up your initial table
idnat <- c(1,1,1,2) #1 is french, 2 is foreign
idbp <- c(1,2,3,4) #1 is mainland, 2 is colony, 3 is overseas, 4 is foreign
t <- cbind(idnat, idbp)
#the last column will be a vector of row length = row length of your matrix
idnat2 <- vector()
#.. and we will populate that vector with a cursor
for(i in 1:length(idnat))
#*check that we selected the cursor to for the length of one of the vectors*
{
if (t[i,1] == 2) #*this says: if idnat = foreign, then it's foreign*
{
idnat2[i] <- 3 #3 is foreign
}
else if (t[i,2] == 1) #*this says: if not foreign and idbp = mainland then it's mainland*
{
idnat2[i] <- 2 # 2 is mainland
}
else #*this says: anything else will be classified as colony or overseas*
{
idnat2[i] <- 1 # 1 is colony or overseas
}
}
cbind(t,idnat2)
This did the trick for me:
var express = require('express'),
app = express();
app.use('/', express.static(__dirname + '/'));
app.listen(8080);
If the link should only change the location if the function run is successful, then do onclick="return runMyFunction();"
and in the function you would return true or false.
If you just want to run the function, and then let the anchor tag do its job, simply remove the return false
statement.
As a side note, you should probably use an event handler instead, as inline JS isn't a very optimal way of doing things.
Bootstrap uses the variable:
$font-size-base: 1rem; // Assumes the browser default, typically 16px
I don't recommend mucking with this, but you can. Best practice is to override the browser default base font size with:
html {
font-size: 14px;
}
Bootstrap will then take that value and use it via rems to set values for all kinds of things.
See http://angular-ui.github.io/bootstrap/#/collapse
function CollapseDemoCtrl($scope) {
$scope.isCollapsed = false;
}
<div ng-controller="CollapseDemoCtrl">
<button class="btn" ng-click="isCollapsed = !isCollapsed">Toggle collapse</button>
<hr>
<div collapse="isCollapsed">
<div class="well well-large">Some content</div>

Doesn't too much matter. Whatever makes you happy will work. There aren't a lot of silly rules because Python projects can be simple.
/scripts
or /bin
for that kind of command-line interface stuff/tests
for your tests/lib
for your C-language libraries/doc
for most documentation/apidoc
for the Epydoc-generated API docs.And the top-level directory can contain README's, Config's and whatnot.
The hard choice is whether or not to use a /src
tree. Python doesn't have a distinction between /src
, /lib
, and /bin
like Java or C has.
Since a top-level /src
directory is seen by some as meaningless, your top-level directory can be the top-level architecture of your application.
/foo
/bar
/baz
I recommend putting all of this under the "name-of-my-product" directory. So, if you're writing an application named quux
, the directory that contains all this stuff is named /quux
.
Another project's PYTHONPATH
, then, can include /path/to/quux/foo
to reuse the QUUX.foo
module.
In my case, since I use Komodo Edit, my IDE cuft is a single .KPF file. I actually put that in the top-level /quux
directory, and omit adding it to SVN.
String is immutable, which means that when you create a string you can never change it. Rather it will create a new string to store the new value, and this can be inefficient if you need to change the value of a string variable a lot.
StringBuilder can be used to simulate a mutable string, so it is good for when you need to change a string a lot.
You could try doing
document.getElementById(id).innerHTML = ajax_response
Use:
SELECT *
FROM `table`
WHERE INSTR(`column`, '{$needle}') > 0
Reference:
Create "libs" folder in app directory copy your jar file in libs folder right click on your jar file in Android Studio and Add As library... Then open build.gradle and add this:
dependencies {
implementation files('libs/your jar file.jar')
}
In case you have smaller data set, a way to achieve it by GUI is:
Reference: http://www.youtube.com/watch?v=tnhJa_zYNVY
In case you use jQuery you need to wait for $(window).load
, because the embedded SVG document might not be yet loaded at $(document).ready
$(window).load(function () {
//alert("Document loaded, including graphics and embedded documents (like SVG)");
var a = document.getElementById("alphasvg");
//get the inner DOM of alpha.svg
var svgDoc = a.contentDocument;
//get the inner element by id
var delta = svgDoc.getElementById("delta");
delta.addEventListener("mousedown", function(){ alert('hello world!')}, false);
});
The problem that global variables create for the programmer is that it expands the inter-component coupling surface between the various components that are using the global variables. What this means is that as the number of components using a global variable increases, the complexity of the interactions can also increase. This increased coupling usually makes defects easier to inject into the system when making changes and also makes defects harder to diagnose and correct. This increase coupling can also reduce the number of available options when making changes and it can increase the effort required for changes as often one must trace through the various modules that are also using the global variable in order to determine the consequences of changes.
The purpose of encapsulation, which is basically the opposite of using global variables, is to decrease coupling in order to make understanding and changing the source easier and safer and more easily tested. It is much easier to use unit testing when global variables are not used.
For example if you have a simple global integer variable that is being used as an enumerated indicator that various components use as a state machine and you then make a change by adding a new state for a new component, you must then trace through all the other components to ensure that the change will not affect them. An example of a possible problem would be if a switch
statement to test the value of the enumeration global variable with case
statements for each of the current values is being used in various places and it so happens that some of the switch
statements do not have a default
case to handle an unexpected value for the global all of a sudden you have undefined behavior so far as the application is concerned.
On the other hand the use of a shared data area might be used to contain a set of global parameters which are referenced throughout the application. This approach is often used with embedded applications with small memory footprints.
When using global variables in these sort of applications typically the responsibility for writing to the data area is allocated to a single component and all other components see the area as const
and read from it, never writing to it. Taking this approach limits the problems that can develop.
A few problems from global variables which need to be worked around
When the source for a global variable such as a struct is modified, everything using it must be recompiled so that everything using the variable knows its true size and memory template.
If more than one component can modify the global variable you can run into problems with inconsistent data being in the global variable. With a multi-threading application, you will probably need to add some kind of locking or critical region to provide a way so that only one thread at a time can modify the global variable and when a thread is modifying the variable, all changes are complete and committed before other threads can query the variable or modify it.
Debugging a multi-threaded application that uses a global variable can be more difficult. You can run into race conditions that can create defects that are difficult to replicate. With several components communicating through a global variable, especially in a multi-threaded application, being able to know what component is changing the variable when and how it is changing the variable can be very difficult to understand.
Name clash can be a problem with using of global variables. A local variable that has the same name as a global variable can hide the global variable. You also run into the naming convention issue when using the C programming language. A work around is to divide the system up into sub-systems with the global variables for a particular sub-system all beginning with the same first three letters (see this on resolving name space collisions in objective C). C++ provides namespaces and with C you can work around this by creating a globally visible struct whose members are various data items and pointers to data and functions which are provided in a file as static hence with file visibility only so that they can only be referenced through the globally visible struct.
In some cases the original application intent is changed so that global variables that provided the state for a single thread is modified to allow several duplicate threads to run. An example would be a simple application designed for a single user using global variables for state and then a request comes down from management to add a REST interface to allow remote applications to act as virtual users. So now you run into having to duplicate the global variables and their state information so that the single user as well as each of the virtual users from remote applications have their own, unique set of global variables.
Using C++ namespace
and the struct
Technique for C
For the C++ programming language the namespace
directive is a huge help in reducing the chances of a name clash. namespace
along with class
and the various access keywords (private
, protected
, and public
) provide most of the tools you need to encapsulate variables. However the C programming language doesn't provide this directive. This stackoverflow posting, Namespaces in C , provides some techniques for C.
A useful technique is to have a single memory resident data area that is defined as a struct
which has global visibility and within this struct
are pointers to the various global variables and functions that are being exposed. The actual definitions of the global variables are given file scope using the static
keyword. If you then use the const
keyword to indicate which are read only, the compiler can help you to enforce read only access.
Using the struct
technique can also encapsulate the global so that it becomes a kind of package or component that happens to be a global. By having a component of this kind it becomes easier to manage changes that affect the global and the functionality using the global.
However while namespace
or the struct
technique can help manage name clashes, the underlying problems of inter-component coupling which the use of globals introduces especially in a modern multi-threaded application, still exist.
Yes. See the relevant page on the R wiki. Short answer: read.xls
from the gdata
package works most of the time (although you need to have Perl installed on your system -- usually already true on MacOS and Linux, but takes an extra step on Windows, i.e. see http://strawberryperl.com/). There are various caveats, and alternatives, listed on the R wiki page.
The only reason I see not to do this directly is that you may want to examine the spreadsheet to see if it has glitches (weird headers, multiple worksheets [you can only read one at a time, although you can obviously loop over them all], included plots, etc.). But for a well-formed, rectangular spreadsheet with plain numbers and character data (i.e., not comma-formatted numbers, dates, formulas with divide-by-zero errors, missing values, etc. etc. ..) I generally have no problem with this process.

Not sure if it's worth anything, but I had a similar problem where I was getting a "java.sql.SQLException: No suitable driver found" error. I found this thread while researching a solution.
The way I ended up solving my problem was to forgo using java.sql.DriverManager to get a connection and instead built up an instance of org.hsqldb.jdbc.jdbcDataSource and used that.
The root cause of my problem (I believe) had to do with the classloader hierarchy and the fact that the JRE was running Java 5. Even though I could successfully load the jdbcDriver class, the classloader behind java.sql.DriverManager was higher up, to the point that it couldn't see the hsqldb.jar I needed.
Anyway, just putting this note here in case someone else stumbles by with a similar problem.
Stringifying a null
value in ActionScript will give the string "NULL"
. My suspicion is that someone has decided that it is, therefore, a good idea to decode the string "NULL"
as null
, causing the breakage you see here -- probably because they were passing in null
objects and getting strings in the database, when they didn't want that (so be sure to check for that kind of bug, too).
I faced this issue when I was tring to link a locally created repo with a blank repo on github.
Initially I was trying git remote set-url
but I had to do git remote add
instead.
git remote add origin https://github.com/VijayNew/NewExample.git
Yes that is valid syntax but it may well not do what you want.
Execution will continue after your RAISERROR
except if you add a RETURN
. So you will need to add a block with BEGIN ... END
to hold the two statements.
Also I'm not sure why you plumped for severity 15. That usually indicates a syntax error.
Finally I'd simplify the conditions using IN
CREATE PROCEDURE [dbo].[AddApplicationUser] (@TenantId BIGINT,
@UserType TINYINT,
@UserName NVARCHAR(100),
@Password NVARCHAR(100))
AS
BEGIN
IF ( @TenantId IS NULL
AND @UserType IN ( 0, 1 ) )
BEGIN
RAISERROR('The value for @TenantID should not be null',15,1);
RETURN;
END
END
If you have a JS array of JSON objects:
var s=['{"Select":"11","PhotoCount":"12"}','{"Select":"21","PhotoCount":"22"}'];
and you want an array of objects:
// JavaScript array of JavaScript objects
var objs = s.map(JSON.parse);
// ...or for older browsers
var objs=[];
for (var i=s.length;i--;) objs[i]=JSON.parse(s[i]);
// ...or for maximum speed:
var objs = JSON.parse('['+s.join(',')+']');
See the speed tests for browser comparisons.
If you have a single JSON string representing an array of objects:
var s='[{"Select":"11","PhotoCount":"12"},{"Select":"21","PhotoCount":"22"}]';
and you want an array of objects:
// JavaScript array of JavaScript objects
var objs = JSON.parse(s);
If you have an array of objects:
// A JavaScript array of JavaScript objects
var s = [{"Select":"11", "PhotoCount":"12"},{"Select":"21", "PhotoCount":"22"}];
…and you want JSON representation for it, then:
// JSON string representing an array of objects
var json = JSON.stringify(s);
…or if you want a JavaScript array of JSON strings, then:
// JavaScript array of strings (that are each a JSON object)
var jsons = s.map(JSON.stringify);

I was having trouble accessing wcf service hosted locally in IIS. Running aspnet_regiis.exe -i wasn't working.
However, I fortunately came across the following:
which informs that servicemodelreg also needs to be run:
Run Visual Studio 2008 Command Prompt as “Administrator”. Navigate to C:\Windows\Microsoft.NET\Framework\v3.0\Windows Communication Foundation. Run this command servicemodelreg –i.
Use IS NULL
or IS NOT NULL
in WHERE-clause instead of ISNULL() method:
SELECT myField1
FROM myTable1
WHERE myField1 IS NOT NULL
There are 3 ways to do so :
1) Simply do SET DEFINE OFF; and then execute the insert stmt.
2) Simply by concatenating reserved word within single quotes and concatenating it. E.g. Select 'Java_22 ' || '& '|| ':' || ' Oracle_14' from dual --(:) is an optional.
3) By using CHR function along with concatenation. E.g. Select 'Java_22 ' || chr(38)||' Oracle_14' from dual
Hope this help !!!
You can pass the data to catboost classifier without encoding. Catboost handles categorical variables itself by performing one-hot and target expanding mean encoding.
This kind of leads to the question when you should use a set and when you should use a list. Usually, the advice goes:
A fourth case that appears often is that you need neither. In this case you see some programmers go with lists and some with sets. Personally I find it very harmful to see set as a list without ordering - because it is really a whole other beast. Unless you need stuff like set uniqueness or set equality, always favor lists.
It depends on the nature of your application. And, since you did not describe it in great detail, it is an impossible question to answer. I find Backbone to be the easiest, but I work in Angular all day. Performance is more up to the coder than the framework, in my opinion.
Are you doing heavy DOM manipulation? I would use jQuery and Backbone.
Very data driven app? Angular with its nice data binding.
Game programming? None - direct to canvas; maybe a game engine.
A common cause for Cannot read property 'fnSetData' of undefined
is the mismatched number of columns, like in this erroneous code:
<thead> <!-- thead required -->
<tr> <!-- tr required -->
<th>Rep</th> <!-- td instead of th will also work -->
<th>Titel</th>
<!-- th missing here -->
</tr>
</thead>
<tbody>
<tr>
<td>Rep</td>
<td>Titel</td>
<td>Missing corresponding th</td>
</tr>
</tbody>
While the following code with one <th>
per <td>
(number of columns must match) works:
<thead>
<tr>
<th>Rep</th> <!-- 1st column -->
<th>Titel</th> <!-- 2nd column -->
<th>Added th</th> <!-- 3rd column; th added here -->
</tr>
</thead>
<tbody>
<tr>
<td>Rep</td> <!-- 1st column -->
<td>Titel</td> <!-- 2nd column -->
<td>th now present</td> <!-- 3rd column -->
</tr>
</tbody>
The error also appears when using a well-formed thead with a colspan but without a second row.
For a table with 7 colums, the following does not work and we see "Cannot read property 'mData' of undefined" in the javascript console:
<thead>
<tr>
<th>Rep</th>
<th>Titel</th>
<th colspan="5">Download</th>
</tr>
</thead>
While this works:
<thead>
<tr>
<th rowspan="2">Rep</th>
<th rowspan="2">Titel</th>
<th colspan="5">Download</th>
</tr>
<tr>
<th>pdf</th>
<th>nwc</th>
<th>nwctxt</th>
<th>mid</th>
<th>xml</th>
</tr>
</thead>
IntelliJ IDEA seems to have reorganized the configurations panel. Now one should go to Editor -> Color Scheme and click on the gears icon to import the theme they want from external .jar
files.
Look here: http://en.cppreference.com/w/cpp/algorithm/sort.
It says:
template< class RandomIt, class Compare >
void sort( RandomIt first, RandomIt last, Compare comp );
bool cmp(const Type1 &a, const Type2 &b);
Also, here's an example of how you can use std::sort
using a custom C++14 polymorphic lambda:
std::sort(std::begin(container), std::end(container),
[] (const auto& lhs, const auto& rhs) {
return lhs.first < rhs.first;
});
Add this to your ajax call:
contentType: "application/json; charset=utf-8",
dataType: "json"
Chances are you need to install .NET 4 (Which will also create a new AppPool for you)
First make sure you have IIS installed then perform the following steps:
cmd
and press ENTERcd C:\Windows\Microsoft.NET\Framework\v4.0.30319\
and press ENTER.aspnet_regiis.exe -ir
and press ENTER again.
-i
instead of -ir
. This will change their AppPools for you and steps 5-on shouldn't be necessary.(You can repeat steps 7-on for every site you want to apply .NET 4 on as well).
Additional References:
-ir
or -i
does (or the difference between them) or what other options are available. (I typically use -ir
to prevent any older sites currently running from breaking on a framework change but that's up to you.)Have been edited in 2020-06-15

There are predefined macros that are used by most compilers, you can find the list here. GCC compiler predefined macros can be found here. Here is an example for gcc:
#if defined(WIN32) || defined(_WIN32) || defined(__WIN32__) || defined(__NT__)
//define something for Windows (32-bit and 64-bit, this part is common)
#ifdef _WIN64
//define something for Windows (64-bit only)
#else
//define something for Windows (32-bit only)
#endif
#elif __APPLE__
#include <TargetConditionals.h>
#if TARGET_IPHONE_SIMULATOR
// iOS Simulator
#elif TARGET_OS_IPHONE
// iOS device
#elif TARGET_OS_MAC
// Other kinds of Mac OS
#else
# error "Unknown Apple platform"
#endif
#elif __linux__
// linux
#elif __unix__ // all unices not caught above
// Unix
#elif defined(_POSIX_VERSION)
// POSIX
#else
# error "Unknown compiler"
#endif
The defined macros depend on the compiler that you are going to use.
The _WIN64
#ifdef
can be nested into the _WIN32
#ifdef
because _WIN32
is even defined when targeting the Windows x64 version. This prevents code duplication if some header includes are common to both
(also WIN32
without underscore allows IDE to highlight the right partition of code).
It is better to process HTML as a template than to build nodes via JavaScript (HTML is not XML after all.) You can keep your IFRAME's HTML syntax clean by using a template and then appending the template's contents into another DIV.
<div id="placeholder"></div>
<script id="iframeTemplate" type="text/html">
<iframe src="...">
<!-- replace this line with alternate content -->
</iframe>
</script>
<script type="text/javascript">
var element,
html,
template;
element = document.getElementById("placeholder");
template = document.getElementById("iframeTemplate");
html = template.innerHTML;
element.innerHTML = html;
</script>
As DimtryB mentioned, by default the keystore is under the user directory. But if you are trying to update the cacerts
file, so that the JVM can pick the keys, then you will have to update the cacerts
file under jre/lib/security
. You can also view the keys by executing the command keytool -list -keystore cacerts
to see if your certificate is added.
Just had to tackle this so thought I would leave my answer. jQuery not required I used to update the element as I already had the object cached.
I first wrote a php function to return the required dates/times to my HTML template
/**
* Gets the current location time based on timezone
* @return string
*/
function get_the_local_time($timezone) {
//$timezone ='Europe/London';
$date = new DateTime('now', new DateTimeZone($timezone));
return array(
'local-machine-time' => $date->format('Y-m-d\TH:i:s+0000'),
'local-time' => $date->format('h:i a')
);
}
This is then used in my HTML template to display an initial time, and render the date format required by javascript in a data attribute.
<span class="box--location__time" data-time="<?php echo $time['local-machine-time']; ?>">
<?php echo $time['local-time']; ?>
</span>
I then used the getUTCHours on my date object to return the time irrespective of the users timezone
The getUTCHours() method returns the hour (from 0 to 23) of the specified date and time, according to universal time.
var initClocks = function() {
var $clocks = $('.box--location__time');
function formatTime(hours, minutes) {
if (hours === 0) {
hours = 12;
}
if (hours < 10) {
hours = "0" + hours;
}
if (minutes < 10) {
minutes = "0" + minutes;
}
return {
hours: hours,
minutes: minutes
}
}
function displayTime(time, $clockDiv) {
var currentTime = new Date(time);
var hours = currentTime.getUTCHours();
var minutes = currentTime.getUTCMinutes();
var seconds = currentTime.getUTCSeconds();
var initSeconds = seconds;
var displayTime = formatTime(hours, minutes);
$clockDiv.html(displayTime.hours + ":" + displayTime.minutes + ":" + seconds);
setInterval(function() {
if (initSeconds > 60) {
initSeconds = 1;
} else {
initSeconds++;
}
currentTime.setSeconds(initSeconds);
hours = currentTime.getUTCHours();
minutes = currentTime.getUTCMinutes();
seconds = currentTime.getUTCSeconds();
displayTime = formatTime(hours, minutes);
$clockDiv.html(displayTime.hours + ":" + displayTime.minutes + ":" + seconds);
}, 1000);
}
$clocks.each(function() {
displayTime($(this).data('time'), $(this));
});
};
I then use the setSeconds method to update the date object based on the amount of seconds past since page load (simple interval function), and update the HTML
You can simply do it like this with an object literal:
function makeGamePlayer(name,totalScore,gamesPlayed) {
return {
name: name,
totalscore: totalScore,
gamesPlayed: gamesPlayed
};
}
So I was looking at all the answers.. didn't like most.. took some from a few.. made this:
const resolveRoutes = (stack) => {
return stack.map(function (layer) {
if (layer.route && layer.route.path.isString()) {
let methods = Object.keys(layer.route.methods);
if (methods.length > 20)
methods = ["ALL"];
return {methods: methods, path: layer.route.path};
}
if (layer.name === 'router') // router middleware
return resolveRoutes(layer.handle.stack);
}).filter(route => route);
};
const routes = resolveRoutes(express._router.stack);
const printRoute = (route) => {
if (Array.isArray(route))
return route.forEach(route => printRoute(route));
console.log(JSON.stringify(route.methods) + " " + route.path);
};
printRoute(routes);
not the prettiest.. but nested, and does the trick
also note the 20 there... I just assume there will not be a normal route with 20 methods.. so I deduce it is all..
This might help:
from datetime import date, timedelta

Your welcome page is set as That Servlet . So all css , images path should be given relative to that servlet DIR . which is a bad idea ! why do you need the servlet as a home page ? set .jsp as index page and redirect to any page from there ?
are you trying to populate any fields from db is that why you are using servlet ?
"Curly Braces" are used in Python to define a dictionary. A dictionary is a data structure that maps one value to another - kind of like how an English dictionary maps a word to its definition.
Python:
dict = {
"a" : "Apple",
"b" : "Banana",
}
They are also used to format strings, instead of the old C style using %, like:
ds = ['a', 'b', 'c', 'd']
x = ['has_{} 1'.format(d) for d in ds]
print x
['has_a 1', 'has_b 1', 'has_c 1', 'has_d 1']
They are not used to denote code blocks as they are in many "C-like" languages.
C:
if (condition) {
// do this
}
If you prefer to know which files the workaround is related to here's what I found. Simple change the .classpath file to
<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="src" path="src"/>
<classpathentry kind="src" path="gen"/>
<classpathentry exported="true" kind="con" path="com.android.ide.eclipse.adt.ANDROID_FRAMEWORK"/>
<classpathentry exported="true" kind="con" path="com.android.ide.eclipse.adt.LIBRARIES"/>
<classpathentry exported="true" kind="con" path="com.android.ide.eclipse.adt.DEPENDENCIES"/>
<classpathentry kind="output" path="bin/classes"/>
</classpath>
Replace the .classpath file in all library projects and in main android project. The .classpath file is in the root folder of the eclipse project. Of cause don't forget to add your own classpath entries, should you have any (so compare with your current version of .classpath).
I believe this is the same result as going through the eclipse menus as componavt-user explained above (Eclipse / Configure Build Path / Order and Export).
The easisest way to get a posted json string, for example, is to read the contents of 'php://input' and then decode it. For example i had a simple Zend route:
'save-json' => array(
'type' => 'Zend\Mvc\Router\Http\Segment',
'options' => array(
'route' => '/save-json/',
'defaults' => array(
'controller' => 'CDB\Controller\Index',
'action' => 'save-json',
),
),
),
and i wanted to post data to it using Angular's $http.post. The post was fine but the retrive method in Zend
$this->params()->fromPost('paramname');
didn't get anything in this case. So my solution was, after trying all kinds of methods like $_POST and the other methods stated above, to read from 'php://':
$content = file_get_contents('php://input');
print_r(json_decode($content));
I got my json array in the end. Hope this helps.
It's entirely likely that a large portion of the developer base comes from a Java background where using ==
to compare strings is wrong and doesn't work.
In C# there's no (practical) difference (for strings) as long as they are typed as string.
If they are typed as object
or T
then see other answers here that talk about generic methods or operator overloading as there you definitely want to use the Equals method.
You've got a couple of issues here.
Firstly, you're defining your code within an anonymous function. This construct:
(function() {
...
)();
does two things. It defines an anonymous function and calls it. There are scope reasons to do this but I'm not sure it's what you actually want.
You're passing in a code block to setTimeout()
. The problem is that update()
is not within scope when executed like that. It however if you pass in a function pointer instead so this works:
(function() {
$(document).ready(function() {update();});
function update() {
$("#board").append(".");
setTimeout(update, 1000); }
}
)();
because the function pointer update
is within scope of that block.
But like I said, there is no need for the anonymous function so you can rewrite it like this:
$(document).ready(function() {update();});
function update() {
$("#board").append(".");
setTimeout(update, 1000); }
}
or
$(document).ready(function() {update();});
function update() {
$("#board").append(".");
setTimeout('update()', 1000); }
}
and both of these work. The second works because the update()
within the code block is within scope now.
I also prefer the $(function() { ... }
shortened block form and rather than calling setTimeout()
within update()
you can just use setInterval()
instead:
$(function() {
setInterval(update, 1000);
});
function update() {
$("#board").append(".");
}
Hope that clears that up.
Try
df.loc[df.my_channel > 20000, 'my_channel'] = 0
Note: Since v0.20.0, ix
has been deprecated in favour of loc
/ iloc
.
Try this all four way to take input with space :)
#include<iostream>
#include<stdio.h>
using namespace std;
void dinput(char *a)
{
for(int i=0;; i++)
{
cin >> noskipws >> a[i];
if(a[i]=='\n')
{
a[i]='\0';
break;
}
}
}
void input(char *a)
{
//cout<<"\nInput string: ";
for(int i=0;; i++)
{
*(a+i*sizeof(char))=getchar();
if(*(a+i*sizeof(char))=='\n')
{
*(a+i*sizeof(char))='\0';
break;
}
}
}
int main()
{
char a[20];
cout<<"\n1st method\n";
input(a);
cout<<a;
cout<<"\n2nd method\n";
cin.get(a,10);
cout<<a;
cout<<"\n3rd method\n";
cin.sync();
cin.getline(a,sizeof(a));
cout<<a;
cout<<"\n4th method\n";
dinput(a);
cout<<a;
return 0;
}
The error "Directory 'blah/.svn' containing working copy admin area is missing" occurred when I attempted to add the directory to the repository, but did not have enough filesystem privileges to do so. The directory was not already in the repository, but it was claiming to be under version control after the failed add.
Checking out a copy of the parent directory to another location, and replacing the .svn folder in the parent dir of the working copy allowed me to add and commit the new directory successfully (after fixing the file permissions, of course).
