This is working for me
Podfile:
platform :ios, '9.0'
use_frameworks!
target '<Your Target Name>' do
pod 'SwiftGifOrigin', '~> 1.7.0'
end
Usage:
// An animated UIImage
let jeremyGif = UIImage.gif(name: "jeremy")
// A UIImageView with async loading
let imageView = UIImageView()
imageView.loadGif(name: "jeremy")
// A UIImageView with async loading from asset catalog(from iOS9)
let imageView = UIImageView()
imageView.loadGif(asset: "jeremy")

This code give an animation like pushing viewController in uinavigation controller...
CATransition *animation = [CATransition animation];
animation.type = kCATransitionPush;
animation.subtype = kCATransitionFromRight;
animation.duration = 0.3;
[_viewAccountName.layer addAnimation:animation forKey:nil];
_viewAccountName.hidden = true;
Used this for pop animation...
CATransition *animation = [CATransition animation];
animation.type = kCATransitionPush;
animation.subtype = kCATransitionFromLeft;
animation.duration = 0.3;
[_viewAccountName.layer addAnimation:animation forKey:nil];
_viewAccountName.hidden = false;
None of the above solved it for me, but this helped: The UIView
animation sets the property immediately, then animates it. It stops the animation when the presentation layer matches the model (the set property).
I solved my issue, which was "I want to animate from where you look like you appear" ('you' meaning the view). If you want THAT, then:
CALayer * pLayer = theView.layer.presentationLayer;
set the position to the presentation layer
I use a few options including UIViewAnimationOptionOverrideInheritedDuration
But because Apple's documentation is vague, I don't know if it really overrides the other animations when used, or just resets timers.
[UIView animateWithDuration:blah...
options: UIViewAnimationOptionBeginFromCurrentState ...
animations: ^ {
theView.center = CGPointMake( pLayer.position.x + YOUR_ANIMATION_OFFSET, pLayer.position.y + ANOTHER_ANIMATION_OFFSET);
//this only works for translating, but you get the idea if you wanna flip and scale it.
} completion: ^(BOOL complete) {}];
And that should be a decent solution for now.
When you log in to your developer account, you can find a link at the bottom of the download section for Xcode that says "Looking for an older version of Xcode?". In there you can find download links to older versions of Xcode and other developer tools
In the HTML which you have shared:
<div id="a">This is some
<div id="b">text</div>
</div>
The text This is some
is within a text node. To depict the text node in a structured way:
<div id="a">
This is some
<div id="b">text</div>
</div>
To extract and print the text This is some
from the text node using Selenium's python client you have 2 ways as follows:
Using splitlines()
: You can identify the parent element i.e. <div id="a">
, extract the innerHTML
and then use splitlines()
as follows:
using xpath:
print(driver.find_element_by_xpath("//div[@id='a']").get_attribute("innerHTML").splitlines()[0])
using xpath:
print(driver.find_element_by_css_selector("div#a").get_attribute("innerHTML").splitlines()[0])
Using execute_script()
: You can also use the execute_script()
method which can synchronously execute JavaScript in the current window/frame as follows:
using xpath and firstChild:
parent_element = driver.find_element_by_xpath("//div[@id='a']")
print(driver.execute_script('return arguments[0].firstChild.textContent;', parent_element).strip())
using xpath and childNodes[n]:
parent_element = driver.find_element_by_xpath("//div[@id='a']")
print(driver.execute_script('return arguments[0].childNodes[1].textContent;', parent_element).strip())
It would be difficult to say if there's any issue with your code without checking it out, however this happens to me quite a lot in (Version 6.0 (6A216f)). I usually have to reset the simulator's Content and Settings and/or restart xCode to get it working again. Try those and see if that solves the problem.
Be careful. For this you need @GET (not @PUT).
Use the TRUNCATE TABLE
command.
You can do it using the same page on the action attribute: action='<yourpage>'
public static void main(String[] args) {
System.out.println(lastDigit(2347));
}
public static int lastDigit(int number)
{
//your code goes here.
int last = number % 10;
return last;
}

This question is old but as it comes up high on search results I will point out that scipy
has two functions for computing the binomial coefficients:
scipy.special.binom()
import scipy.special
# the two give the same results
scipy.special.binom(10, 5)
# 252.0
scipy.special.comb(10, 5)
# 252.0
scipy.special.binom(300, 150)
# 9.375970277281882e+88
scipy.special.comb(300, 150)
# 9.375970277281882e+88
# ...but with `exact == True`
scipy.special.comb(10, 5, exact=True)
# 252
scipy.special.comb(300, 150, exact=True)
# 393759702772827452793193754439064084879232655700081358920472352712975170021839591675861424
Note that scipy.special.comb(exact=True)
uses Python integers, and therefore it can handle arbitrarily large results!
Speed-wise, the three versions give somewhat different results:
num = 300
%timeit [[scipy.special.binom(n, k) for k in range(n + 1)] for n in range(num)]
# 52.9 ms ± 107 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)
%timeit [[scipy.special.comb(n, k) for k in range(n + 1)] for n in range(num)]
# 183 ms ± 814 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)each)
%timeit [[scipy.special.comb(n, k, exact=True) for k in range(n + 1)] for n in range(num)]
# 180 ms ± 649 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)
(and for n = 300
, the binomial coefficients are too large to be represented correctly using float64
numbers, as shown above).
How about this?
for item in mylist:
if item in checklist:
pass
else:
# do something
print item
You need to close the connection before you can use the output parameters. Something like this
con.Close();
MessageBox.Show(cmd.Parameters["@code"].Value.ToString());
In jQuery 1.2 and newer you no longer have to position the element absolutely; you can use normal relative positioning and use += or -= to add to or subtract from properties, e.g.
$("#startAnimation").click(function(){
$(".toBeAnimated").animate({
marginLeft: "+=250px",
}, 1000 );
});
And to echo the guy who answered first's advice: Javascript is not performant. Don't overuse animations, or expect things than run nice and fast on your high performance PC on Chrome to look good on a bog-standard PC running IE. Test it, and make sure it degrades well!
On a Mac: Quit Chrome, then run the following command in a terminal window:
open -a "Google Chrome" --args --auto-open-devtools-for-tabs
For any OS
This helped me so I'll put it here, just in case.
Once you are done with adding the rsa keys for both the accounts, add a config file in your .ssh
directory for both the accounts (.ssh/config
)
# First account
Host github.com-<FIRST_ACCOUNT_USERNAME_HERE>
HostName github.com
User git
IdentityFile ~/.ssh/id_rsa_user1
# Second account
Host github.com-<SECOND_ACCOUNT_USERNAME_HERE>
HostName github.com
User git
IdentityFile ~/.ssh/id_rsa_user2
Make sure you use the correct usernames and RSA files. Next, you can open the terminal/git bash on the repository root and check which account you would be pushing from
git config user.email
Suppose this returns the first user email and you want to push from the second user. Change the local user.name
and user.email
:
git config user.name "SECOND_USER"
git config user.email "[email protected]"
(This won't change the global config and you can have the first user set up as the global user). Once done, you can confirm with git config user.email
and it should return the email of the second user. You're all set to push to GitHub with the second user. The rest is all the same old git add
, git commit
and git push
.
To push from the first user, change the local user.name
again and follow the same steps.
Hope it helps :)
If the above steps are still not working for you, check to see if you have uploaded the RSA keys within GitHub portal. Refer to GitHub documentation:
Then, clear your ssh cached keys Reference
ssh-add -D
Then add you 2 ssh keys
ssh-add ~/.ssh/id_rsa_user1
ssh-add ~/.ssh/id_rsa_user2
Then type in your terminal:
ssh -T [email protected]<SECOND_ACCOUNT_USERNAME_HERE>
You should see the following output:
Hi <SECOND_USERNAME>! You've successfully authenticated, but GitHub does not provide shell access.
Then, assign the correct remote to your local repository. Make sure you put the same username as the one you gave in your .ssh/config
file next to Host
. In the following case [email protected]<SECOND_ACCOUNT_USERNAME_HERE>
.
git remote rm origin
git remote add origin [email protected]<SECOND_ACCOUNT_USERNAME_HERE>:/your_username/your_repository.git
<sup>
and <sub>
tags work and are your only good solution for arbitrary text. Other solutions include:
Unicode
If the superscript (or subscript) you need is of a mathematical nature, Unicode may well have you covered.
I've compiled a list of all the Unicode super and subscript characters I could identify in this gist. Some of the more common/useful ones are:
°
SUPERSCRIPT ZERO (U+2070)¹
SUPERSCRIPT ONE (U+00B9)²
SUPERSCRIPT TWO (U+00B2)³
SUPERSCRIPT THREE (U+00B3)n
SUPERSCRIPT LATIN SMALL LETTER N (U+207F)People also often reach for <sup>
and <sub>
tags in an attempt to render specific symbols like these:
™
TRADE MARK SIGN (U+2122)®
REGISTERED SIGN (U+00AE)?
SERVICE MARK (U+2120)Assuming your editor supports Unicode, you can copy and paste the characters above directly into your document.
Alternatively, you could use the hex values above in an HTML character escape. Eg, ²
instead of ²
. This works with GitHub (and should work anywhere else your Markdown is rendered to HTML) but is less readable when presented as raw text/Markdown.
Images
If your requirements are especially unusual, you can always just inline an image. The GitHub supported syntax is:
![Alt text goes here, if you'd like](path/to/image.png)
You can use a full path (eg. starting with https://
or http://
) but it's often easier to use a relative path, which will load the image from the repo, relative to the Markdown document.
If you happen to know LaTeX (or want to learn it) you could do just about any text manipulation imaginable and render it to an image. Sites like Quicklatex make this quite easy.
I think that biases are almost always helpful. In effect, a bias value allows you to shift the activation function to the left or right, which may be critical for successful learning.
It might help to look at a simple example. Consider this 1-input, 1-output network that has no bias:
The output of the network is computed by multiplying the input (x) by the weight (w0) and passing the result through some kind of activation function (e.g. a sigmoid function.)
Here is the function that this network computes, for various values of w0:
Changing the weight w0 essentially changes the "steepness" of the sigmoid. That's useful, but what if you wanted the network to output 0 when x is 2? Just changing the steepness of the sigmoid won't really work -- you want to be able to shift the entire curve to the right.
That's exactly what the bias allows you to do. If we add a bias to that network, like so:
...then the output of the network becomes sig(w0*x + w1*1.0). Here is what the output of the network looks like for various values of w1:
Having a weight of -5 for w1 shifts the curve to the right, which allows us to have a network that outputs 0 when x is 2.
Here is a screenshot of me fixing this. I've encountered it many times, and it's always due to this config-related jazz:
Event Log
(bottom right)Configure
of the Android Framework detected notificationIf you do this and your icon still isn't lit up, then you probably need to set up the emulator still. I would recommend investigating the SDK Manager
if so.
It's because there can only be one definition of A::a
that all the translation units use.
If you performed static int a = 3;
in a class in a header included in all a translation units then you'd get multiple definitions. Therefore, non out-of-line definition of a static is forcibly made a compiler error.
Using static inline
or static const
remedies this. static inline
only concretises the symbol if it is used in the translation unit and ensures the linker only selects and leaves one copy if it's defined in multiple translation units due to it being in a comdat group. const
at file scope makes the compiler never emit a symbol because it's always substituted immediately in the code unless extern
is used, which is not permitted in a class.
One thing to note is static inline int b;
is treated as a definition whereas static const int b
or static const A b;
are still treated as a declaration and must be defined out-of-line if you don't define it inside the class. Interestingly static constexpr A b;
is treated as a definition, whereas static constexpr int b;
is an error and must have an initialiser (this is because they now become definitions and like any const/constexpr definition at file scope, they require an initialiser which an int doesn't have but a class type does because it has an implicit = A()
when it is a definition -- clang allows this but gcc requires you to explicitly initialise or it is an error. This is not a problem with inline instead). static const A b = A();
is not allowed and must be constexpr
or inline
in order to permit an initialiser for a static object with class type i.e to make a static member of class type more than a declaration. So yes in certain situations A a;
is not the same as explicitly initialising A a = A();
(the former can be a declaration but if only a declaration is allowed for that type then the latter is an error. The latter can only be used on a definition. constexpr
makes it a definition). If you use constexpr
and specify a default constructor then the constructor will need to be constexpr
#include<iostream>
struct A
{
int b =2;
mutable int c = 3; //if this member is included in the class then const A will have a full .data symbol emitted for it on -O0 and so will B because it contains A.
static const int a = 3;
};
struct B {
A b;
static constexpr A c; //needs to be constexpr or inline and doesn't emit a symbol for A a mutable member on any optimisation level
};
const A a;
const B b;
int main()
{
std::cout << a.b << b.b.b;
return 0;
}
A static member is an outright file scope declaration extern int A::a;
(which can only be made in the class and out of line definitions must refer to a static member in a class and must be definitions and cannot contain extern) whereas a non-static member is part of the complete type definition of a class and have the same rules as file scope declarations without extern
. They are implicitly definitions. So int i[]; int i[5];
is a redefinition whereas static int i[]; int A::i[5];
isn't but unlike 2 externs, the compiler will still detect a duplicate member if you do static int i[]; static int i[5];
in the class.
You can use matching groups:
p = re.compile('name (.*) is valid')
e.g.
>>> import re
>>> p = re.compile('name (.*) is valid')
>>> s = """
... someline abc
... someother line
... name my_user_name is valid
... some more lines"""
>>> p.findall(s)
['my_user_name']
Here I use re.findall
rather than re.search
to get all instances of my_user_name
. Using re.search
, you'd need to get the data from the group on the match object:
>>> p.search(s) #gives a match object or None if no match is found
<_sre.SRE_Match object at 0xf5c60>
>>> p.search(s).group() #entire string that matched
'name my_user_name is valid'
>>> p.search(s).group(1) #first group that match in the string that matched
'my_user_name'
As mentioned in the comments, you might want to make your regex non-greedy:
p = re.compile('name (.*?) is valid')
to only pick up the stuff between 'name '
and the next ' is valid'
(rather than allowing your regex to pick up other ' is valid'
in your group.
This works in Oracle:
insert into pager (PAG_ID,PAG_PARENT,PAG_NAME,PAG_ACTIVE)
select 8000,0,'Multi 8000',1 from dual
union all select 8001,0,'Multi 8001',1 from dual
The thing to remember here is to use the from dual
statement.
You can use strptime(3)
to parse the time, and then mktime(3)
to convert it to a time_t
:
const char *time_details = "16:35:12";
struct tm tm;
strptime(time_details, "%H:%M:%S", &tm);
time_t t = mktime(&tm); // t is now your desired time_t
To diagnose it, follow this answer.
But to fix it, knowing you are the only one changing it, do:
1 - backup your project (I did only the files on git, ./src folder)
2 - git pull
3 - restore you backup over the many "messed" files (with merge indicators)
I tried git pull -s recursive -X ours
but didnt work the way I wanted, it could be an option tho, but backup first!!!
Make sure the differences/changes (at git gui) are none. This is my case, there is nothing to merge at all, but github keeps saying I should merge...
As I always say nothing is impossible:
string value = "super exemple of string key : text I want to keep - end of my string";
Regex regex = new Regex(@"(key \: (.*?) _ )");
Match match = regex.Match(value);
if (match.Success)
{
Messagebox.Show(match.Value);
}
Remeber that should add reference of System.Text.RegularExpressions
Hope That I Helped.
you first would need to convert string into datetime tuple, and then convert that datetime tuple to string, it would go like this:
lastconnection = datetime.strptime("21/12/2008", "%d/%m/%Y").strftime('%Y-%m-%d')
in visual studio you can also do like that to pass simply or avoiding from comandline argument
static void Main(string[] args)
{
if (args == null)
{
Console.WriteLine("args is null"); // Check for null array
}
else
{
args=new string[2];
args[0] = "welcome in";
args[1] = "www.overflow.com";
Console.Write("args length is ");
Console.WriteLine(args.Length); // Write array length
for (int i = 0; i < args.Length; i++) // Loop through array
{
string argument = args[i];
Console.Write("args index ");
Console.Write(i); // Write index
Console.Write(" is [");
Console.Write(argument); // Write string
Console.WriteLine("]");
}
}
You can do something like this to show blank space:
=IF(AND((E2-D2)>0)=TRUE,E2-D2," ")
Inside if
before first comma is condition then result and return value if true
and last in value as blank if condition is false
Sometimes, a textual representation might also help; with this query on the system catalog views, you can get a list of all FK relationships and how the link two tables (and what columns they operate on).
SELECT
fk.name 'FK Name',
tp.name 'Parent table',
cp.name, cp.column_id,
tr.name 'Refrenced table',
cr.name, cr.column_id
FROM
sys.foreign_keys fk
INNER JOIN
sys.tables tp ON fk.parent_object_id = tp.object_id
INNER JOIN
sys.tables tr ON fk.referenced_object_id = tr.object_id
INNER JOIN
sys.foreign_key_columns fkc ON fkc.constraint_object_id = fk.object_id
INNER JOIN
sys.columns cp ON fkc.parent_column_id = cp.column_id AND fkc.parent_object_id = cp.object_id
INNER JOIN
sys.columns cr ON fkc.referenced_column_id = cr.column_id AND fkc.referenced_object_id = cr.object_id
ORDER BY
tp.name, cp.column_id
Dump this into Excel, and you can slice and dice - based on the parent table, the referenced table or anything else.
I find visual guides helpful - but sometimes, textual documentation is just as good (or even better) - just my 2 cents.....
The socket has been closed by the client (browser).
A bug in your code:
byte[] outputByte=new byte[4096];
while(in.read(outputByte,0,4096)!=-1){
output.write(outputByte,0,4096);
}
The last packet read, then write may have a length < 4096, so I suggest:
byte[] outputByte=new byte[4096];
int len;
while(( len = in.read(outputByte, 0, 4096 )) > 0 ) {
output.write( outputByte, 0, len );
}
It's not your question, but it's my answer... ;-)
Since for me, some elements are created on page load, and some are dynamically added by the user; I used this to make sure everything stayed DRY.
On submit, find everything with class x, remove class x, add rule x.
$('#form').on('submit', function(e) {
$('.alphanumeric_dash').each(function() {
var $this = $(this);
$this.removeClass('alphanumeric_dash');
$(this).rules('add', {
alphanumeric_dash: true
});
});
});
Try this:
Custom formula is
=countif(A:A,A1)>1
(or change A
to your chosen column)A1:A100
).Anything written in the A1:A100 cells will be checked, and if there is a duplicate (occurs more than once) then it'll be coloured.
For locales using comma (,
) as a decimal separator, the argument separator is most likely a semi-colon (;
). That is, try: =countif(A:A;A1)>1
, instead.
For multiple columns, use countifs
.

Complementing the above answers and also "Parroting" from the Windows Dev Center documentation,
The Winsock2.h header file internally includes core elements from the Windows.h header file, so there is not usually an #include line for the Windows.h header file in Winsock applications. If an #include line is needed for the Windows.h header file, this should be preceded with the #define WIN32_LEAN_AND_MEAN macro. For historical reasons, the Windows.h header defaults to including the Winsock.h header file for Windows Sockets 1.1. The declarations in the Winsock.h header file will conflict with the declarations in the Winsock2.h header file required by Windows Sockets 2.0. The WIN32_LEAN_AND_MEAN macro prevents the Winsock.h from being included by the Windows.h header ..

You want to be using the iframe's srcdoc
attribute for that (MDN documentation).
var html_string = "<html><body><h1>My epic iframe</p></body></html>";
document.querySelector('iframe').srcdoc = html_string;
The nice thing about using this method over for example Red's method listed on this page, is that iframe contents added with srcdoc
are seen as the same-origin. That way can continue to manipulate and access the iframe with JavaScript if you wish.
Replace the line in htpasswd file:
go to: http://www.htaccesstools.com/htpasswd-generator-windows/
(if the link is expired, search another generator from google.com)
Enter your username and password. The site will generate encrypted line. Copy that line and replace it with the previous line in the file "repo/htpasswd".
You might also need to 'clear' the 'Authentication data' from tortoisSVN -> settings -> saved data
I have never considered it to be a bad practice to throw an exception in the constructor. When the class is designed, you have a certain idea in mind of what the structure for that class should be. If someone else has a different idea and tries to execute that idea, then you should error accordingly, giving the user feedback on what the error is. In your case, you might consider something like
if (age < 0) throw new NegativeAgeException("The person you attempted " +
"to construct must be given a positive age.");
where NegativeAgeException
is an exception class that you constructed yourself, possibly extending another exception like IndexOutOfBoundsException
or something similar.
Assertions don't exactly seem to be the way to go, either, since you're not trying to discover bugs in your code. I would say terminating with an exception is absolutely the right thing to do here.
Numbers in JS use a .
(full stop / period) character to indicate the decimal point not a ,
(comma).
if u want to use them as an array u already knew, else u can use every one of them as a different parameter ... try this :
parameter1,parameter2,parameter3,parameter4,parameter5 = ex.split(",")
I did it with transparent *.cur 1px to 1px, but it looks like small dot. :( I think it's the best cross-browser thing that I can do. CSS2.1 has no value 'none' for 'cursor' property - it was added in CSS3. Thats why it's workable not everywhere.

so I have a solution that isn't perfect but it worked for me. Use the polygon example from Google, and use the pinpoint on Google Maps to get lat & long locations.
I used what I call "ocular copy & paste" where you look at the screen and then write in the numbers you want ;-)
<style>
#map {
height: 500px;
}
</style>
<script>
// This example creates a simple polygon representing the host city of the
// Greatest Outdoor Show On Earth.
function initMap() {
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 9,
center: {lat: 51.039, lng: -114.204},
mapTypeId: 'terrain'
});
// Define the LatLng coordinates for the polygon's path.
var triangleCoords = [
{lat: 51.183, lng: -114.234},
{lat: 51.154, lng: -114.235},
{lat: 51.156, lng: -114.261},
{lat: 51.104, lng: -114.259},
{lat: 51.106, lng: -114.261},
{lat: 51.102, lng: -114.272},

This gets you the outline for Calgary. I've attached an image here.
Basically you are doing it the right way. However, you should use an instance of the DataContext
for querying (it's not obvious that DataContext
is an instance or the type name from your query):
var result = (from a in new DataContext().Persons
where a.Age > 18
select new Person { Name = a.Name, Age = a.Age }).ToList();
Apparently, the Person
class is your LINQ to SQL generated entity class. You should create your own class if you only want some of the columns:
class PersonInformation {
public string Name {get;set;}
public int Age {get;set;}
}
var result = (from a in new DataContext().Persons
where a.Age > 18
select new PersonInformation { Name = a.Name, Age = a.Age }).ToList();
You can freely swap var
with List<PersonInformation>
here without affecting anything (as this is what the compiler does).
Otherwise, if you are working locally with the query, I suggest considering an anonymous type:
var result = (from a in new DataContext().Persons
where a.Age > 18
select new { a.Name, a.Age }).ToList();
Note that in all of these cases, the result
is statically typed (it's type is known at compile time). The latter type is a List
of a compiler generated anonymous class similar to the PersonInformation
class I wrote above. As of C# 3.0, there's no dynamic typing in the language.
If you really want to return a List<Person>
(which might or might not be the best thing to do), you can do this:
var result = from a in new DataContext().Persons
where a.Age > 18
select new { a.Name, a.Age };
List<Person> list = result.AsEnumerable()
.Select(o => new Person {
Name = o.Name,
Age = o.Age
}).ToList();
You can merge the above statements too, but I separated them for clarity.
Update: This answer may be incorrect or out of date. Please see comments for details.
I switched from @Inject
to @EJB
because @EJB
allows circular injection whereas @Inject
pukes on it.
Details: I needed @PostConstruct
to call an @Asynchronous
method but it would do so synchronously. The only way to make the asynchronous call was to have the original call a method of another bean and have it call back the method of the original bean. To do this each bean needed a reference to the other -- thus circular. @Inject
failed for this task whereas @EJB
worked.
It is typically considered good practice to default to the lowest visibility required as this promotes data encapsulation and good interface design. When considering member variable and method visibility think about the role the member plays in the interaction with other objects.
If you "code to an interface rather than implementation" then it's usually pretty straightforward to make visibility decisions. In general, variables should be private or protected unless you have a good reason to expose them. Use public accessors (getters/setters) instead to limit and regulate access to a class's internals.
To use a car as an analogy, things like speed, gear, and direction would be private instance variables. You don't want the driver to directly manipulate things like air/fuel ratio. Instead, you expose a limited number of actions as public methods. The interface to a car might include methods such as accelerate()
, deccelerate()
/brake()
, setGear()
, turnLeft()
, turnRight()
, etc.
The driver doesn't know nor should he care how these actions are implemented by the car's internals, and exposing that functionality could be dangerous to the driver and others on the road. Hence the good practice of designing a public interface and encapsulating the data behind that interface.
This approach also allows you to alter and improve the implementation of the public methods in your class without breaking the interface's contract with client code. For example, you could improve the accelerate()
method to be more fuel efficient, yet the usage of that method would remain the same; client code would require no changes but still reap the benefits of your efficiency improvement.
Edit: Since it seems you are still in the midst of learning object oriented concepts (which are much more difficult to master than any language's syntax), I highly recommend picking up a copy of PHP Objects, Patterns, and Practice by Matt Zandstra. This is the book that first taught me how to use OOP effectively, rather than just teaching me the syntax. I had learned the syntax years beforehand, but that was useless without understanding the "why" of OOP.

I suggest you search the blogs of Jason Massie (http://statisticsio.com/) and Brent Ozar (http://www.brentozar.com/) for related info. They have some post about real-life scenario that deals with indexes.
None of these answers worked for me. I'm now using:
document.addEventListener('dragleave', function(e){
var top = e.pageY;
var right = document.body.clientWidth - e.pageX;
var bottom = document.body.clientHeight - e.pageY;
var left = e.pageX;
if(top < 10 || right < 20 || bottom < 10 || left < 10){
console.log('Mouse has moved out of window');
}
});
I'm using this for a drag and drop file uploading widget. It's not absolutely accurate, being triggered when the mouse gets to a certain distance from the edge of the window.
Use of "and" in conditional. I often use this when importing in Jupyter Notebook:
def find_local_py_scripts():
import os # does not cost if already imported
for entry in os.scandir('.'):
# find files ending with .py
if entry.is_file() and entry.name.endswith(".py") :
print("- ", entry.name)
find_local_py_scripts()
- googlenet_custom_layers.py
- GoogLeNet_Inception_v1.py
==EDIT==
I checked your question again and have concluded this can't be done.
ProductName is not unique, It must either be part of the Group By
or excluded from your results.
For example how would SQL present these results to you if you Group By
only ProductID?
ProductID | ProductName | OrderQuantity
---------------------------------------
1234 | abc | 1
1234 | def | 1
1234 | ghi | 1
1234 | jkl | 1
This generates a random number between 0-9
SELECT ABS(CHECKSUM(NEWID()) % 10)
1 through 6
SELECT ABS(CHECKSUM(NEWID()) % 6) + 1
3 through 6
SELECT ABS(CHECKSUM(NEWID()) % 4) + 3
Dynamic (Based on Eilert Hjelmeseths Comment, updated to fix bug( + to -))
SELECT ABS(CHECKSUM(NEWID()) % (@max - @min - 1)) + @min
Updated based on comments:
NEWID
generates random string (for each row in return)CHECKSUM
takes value of string and creates number%
) divides by that number and returns the remainder (meaning max value is one less than the number you use)ABS
changes negative results to positiveIf you're using Python 3, just execute python3 get-pip.py
. It is just a simple command.
Use jQuery DataTables plug-in, it supports fixed header and columns. This example adds fixed column support to the html table "example":

margin
to align images:Since we wanted the image
to be left-aligned
, we added:
img {
margin-right: auto;
}
Similarly for image
to be right-aligned
, we can add margin-right: auto;
. The snippet shows a demo for both types of alignment.
Good Luck...

Here is a more structured/flexible approach: (Swift 3)
struct StopWatch {
var totalSeconds: Int
var years: Int {
return totalSeconds / 31536000
}
var days: Int {
return (totalSeconds % 31536000) / 86400
}
var hours: Int {
return (totalSeconds % 86400) / 3600
}
var minutes: Int {
return (totalSeconds % 3600) / 60
}
var seconds: Int {
return totalSeconds % 60
}
//simplified to what OP wanted
var hoursMinutesAndSeconds: (hours: Int, minutes: Int, seconds: Int) {
return (hours, minutes, seconds)
}
}
let watch = StopWatch(totalSeconds: 27005 + 31536000 + 86400)
print(watch.years) // Prints 1
print(watch.days) // Prints 1
print(watch.hours) // Prints 7
print(watch.minutes) // Prints 30
print(watch.seconds) // Prints 5
print(watch.hoursMinutesAndSeconds) // Prints (7, 30, 5)
Having an approach like this allows the adding of convenience parsing like this:
extension StopWatch {
var simpleTimeString: String {
let hoursText = timeText(from: hours)
let minutesText = timeText(from: minutes)
let secondsText = timeText(from: seconds)
return "\(hoursText):\(minutesText):\(secondsText)"
}
private func timeText(from number: Int) -> String {
return number < 10 ? "0\(number)" : "\(number)"
}
}
print(watch.simpleTimeString) // Prints 07:30:05
It should be noted that purely Integer based approaches don't take leap day/seconds into account. If the use case is dealing with real dates/times Date and Calendar should be used.
This was the most simple way to do it imo and it worked for me.
.table-hover tbody tr:hover td {
background: aqua;
}
Not sure why you would want to change the heading color to the same hover color as the rows but if you do then you can use the above solutions. If you just want t
There is another reason for using "like" even if the performance is slower: Character values are implicitly converted to integer when compared, so:
declare @transid varchar(15)
if @transid != 0
will give you a "The conversion of the varchar value '123456789012345' overflowed an int column" error.
You can do it programatically:
import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
import android.view.WindowManager;
public class ActivityName extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// remove title
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main);
}
}
Or you can do it via your AndroidManifest.xml
file:
<activity android:name=".ActivityName"
android:label="@string/app_name"
android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen">
</activity>
Edit: I added some lines so that you can show it in fullscreen, as it seems that's what you want.
@RequestMapping(value = "/uploadImageJson", method = RequestMethod.POST)

I tried the previous answer and doesn't seem to be working the $("body").height() does not necessarily represent the whole html height.
I have corrected the solution as follows:
// Check if body height is higher than window height :)
if ($(document).height() > $(window).height()) {
alert("Vertical Scrollbar! D:");
}
// Check if body width is higher than window width :)
if ($(document).width() > $(window).width()) {
alert("Horizontal Scrollbar! D:<");
}
At the time of writing, there was a bug in chrome which required an xmlns

There is no problem in deleting this. It's not only the WebStorm IDE creating this file, but also PhpStorm and all other of JetBrains' IDEs.
It is safe to delete it but if your project is from GitLab or GitHub then you will see a warning.
These are the options currently documented in the tests: ctrl, shift, enter and escape. These are some valid examples of key bindings:

keydown.control.esc
You can track this here while no official docs exist, but they should be out soon.
First we grab the command output, then wrap it and select one of its properties. There is only one and its "Name" which is what we want. So we select the groups property with ".name" then output it.

I got the same problem while running unit tests. I found this workaround solution:
The following workaround allows to get rid of this message:
File workaround = new File(".");
System.getProperties().put("hadoop.home.dir", workaround.getAbsolutePath());
new File("./bin").mkdirs();
new File("./bin/winutils.exe").createNewFile();
You actually do not want to get the path to your main class. According to your example you want to get the current working directory, i.e. directory where your program started. In this case you can just say new File(".").getAbsolutePath()

Shared Preferences are the key/value pairs that we can store. They are internal type of storage which means we do not have to create an external database to store it. To see it go to, 1) Go to View in the menu bar. Select Tool Windows. 2) Click on Device File Explorer. 3) Device File Explorer opens up in the right hand side. 4) Find the data folder and click on it. 5) In the data folder, you can select another data folder. 6) Try to search for your package name in this data folder. Ex: com.example.com 7) Then Click on shared_prefs and open the .xml file.
Hope this helps!
I also ran into this problem and probably found the solution that may help. The key is launching the AVD in the emulator first then run your App.
Following are the steps:
When you generate a JAXB model from an XML Schema, global elements that correspond to named complex types will have that metadata captured as an @XmlElementDecl
annotation on a create method in the ObjectFactory
class. Since you are creating the JAXBContext
on just the DocumentType
class this metadata isn't being processed. If you generated your JAXB model from an XML Schema then you should create the JAXBContext
on the generated package name or ObjectFactory
class to ensure all the necessary metadata is processed.
Example solution:
JAXBContext jaxbContext = JAXBContext.newInstance(my.generatedschema.dir.ObjectFactory.class);
DocumentType documentType = ((JAXBElement<DocumentType>) jaxbContext.createUnmarshaller().unmarshal(inputStream)).getValue();
$files = glob($_SERVER["DOCUMENT_ROOT"]."/myFolder/*");

You missed single quote sign:
SELECT *
FROM TABLENAME
WHERE DateTime >= '12/04/2011 12:00:00 AM' AND DateTime <= '25/05/2011 3:53:04 AM'
Also, it is recommended to use ISO8601 format YYYY-MM-DDThh:mm:ss.nnn[ Z ], as this one will not depend on your server's local culture.
SELECT *
FROM TABLENAME
WHERE
DateTime >= '2011-04-12T00:00:00.000' AND
DateTime <= '2011-05-25T03:53:04.000'
Height is supported to auto.
Width is not!
To do some sort of auto get the size of the div you are showing and then set the window with.
In the C# code..
TheDiv.Style["width"] = "200px";
private void setWindowSize(int width, int height)
{
string widthScript = "$('.dialogDiv').dialog('option', 'width', " + width +");";
string heightScript = "$('.dialogDiv').dialog('option', 'height', " + height + ");";
ScriptManager.RegisterStartupScript(this.Page, this.GetType(),
"scriptDOWINDOWSIZE",
"<script type='text/javascript'>"
+ widthScript
+ heightScript +
"</script>", false);
}
What worked for me is ,,,

Expand the left tree, right-click your WebSite>Properties
Click on Directory Security, then in "Anonymous access and authentication control" click on Edit
Enable Anonymous access>browse> enter the credentials of the admin (like Administrator) (check names),> Click OK
Apply the settings and it should work fine.
Use find:
find . -name \*.txt -print
On systems that use GNU find, like most GNU/Linux distributions, you can leave out the -print.
You can use lodash sortBy (https://lodash.com/docs/4.17.4#sortBy).
Your code could be like:
const myArray = [
{
"id":25,
"name":"Anakin Skywalker",
"createdAt":"2017-04-12T12:48:55.000Z",
"updatedAt":"2017-04-12T12:48:55.000Z"
},
{
"id":1,
"name":"Luke Skywalker",
"createdAt":"2017-04-12T11:25:03.000Z",
"updatedAt":"2017-04-12T11:25:03.000Z"
}
]
const myOrderedArray = _.sortBy(myArray, o => o.name)
Use the SC

this method also encounter a deprecate warning:
org.junit.Assert.assertEquals(float expected,float actual) //deprecated
It is because currently junit prefer a third parameter rather than just two float variables input.
The third parameter is delta:
public static void assertEquals(double expected,double actual,double delta) //replacement
this is mostly used to deal with inaccurate Floating point calculations
for more information, please refer this problem: Meaning of epsilon argument of assertEquals for double values
Somehow, where you are using Sentry, you're not using its Facade, but the class itself. When you call a class through a Facade you're not really using statics, it's just looks like you are.
Do you have this:
use Cartalyst\Sentry\Sentry;
In your code?
Ok, but if this line is working for you:
$user = $this->sentry->register(array( 'username' => e($data['username']), 'email' => e($data['email']), 'password' => e($data['password']) ));
So you already have it instantiated and you can surely do:
$adminGroup = $this->sentry->findGroupById(5);
The Dr. Memory (http://drmemory.org) tool comes with a system call tracing tool called drstrace that lists all system calls made by a target application along with their arguments: http://drmemory.org/strace_for_windows.html
For programmatically enforcing system call policies, you could use the same underlying engines as drstrace: the DynamoRIO tool platform (http://dynamorio.org) and the DrSyscall system call monitoring library (http://drmemory.org/docs/page_drsyscall.html). These use dynamic binary translation technology, which does incur some overhead (20%-30% in steady state, but much higher when running new code such as launching a big desktop app), which may or may not be suitable for your purposes.
This worked perfectly fine for me. Add the annotation @JsonIgnore on the child class where you mention the reference to the parent class.
@ManyToOne
@JoinColumn(name = "ID", nullable = false, updatable = false)
@JsonIgnore

Well, I understand that
- Node's goal is to provide an easy way to build scalable network programs.
- Node is similar in design to and influenced by systems like Ruby's Event Machine or Python's Twisted.
- Evented I/O for V8 javascript.
For me that means that you were correct in all three assumptions. The library sure looks promising!
I have used paramiko a bunch (nice) and pxssh (also nice). I would recommend either. They work a little differently but have a relatively large overlap in usage.
In the logging world there are Facades (like Apache Commons Logging, slf4j or even the Log4j 2.0 API) and implementations (Log4j 1 + 2, java.util.logging, TinyLog, Logback).
Basically you should replace your selfmade wrapper with slf4j IF and only IF you are not happy with it for some reason. While Apache Commons Logging is not really providing a modern API, slf4j and the new Log4j 2 facade is providing that. Given that quite a bunch of apps use slf4j as a wrapper it might make sense to use that.
slf4j gives a number of nice API sugar, like this example from slf4j docs:
logger.debug("Temperature set to {}. Old temperature was {}.", t, oldT);
It's variable substitution. This is also supported by Log4j 2.
However you need to be aware that slf4j is developed by QOS who also maintain logback. Log4j 2.0 is baked in the Apache Software Foundation. In the past three years a vibrant and active community has grown there again. If you appreciate Open Source as it is done by the Apache Software Foundation with all its guarantees you might reconsider using slf4j in favor to use Log4j 2 directly.
Please note:
In the past log4j 1 was not actively maintained while Logback was. But today things are different. Log4j 2 is actively maintained and releases on almost regular schedule. It also includes lot of modern features and -imho- makes a couple of things better than Logback. This is sometimes just a matter of taste and you should draw your own conclusions.
I wrote a quick overview on the new Features of Log4j 2.0: http://www.grobmeier.de/the-new-log4j-2-0-05122012.html
When reading you will see that Log4j 2 was inspired by Logback but also by other logging frameworks. But the code base is different; it shares almost nothing with Log4j 1 and zero with Logback. This lead to some improvements like in example Log4j 2 operates with bytestreams instead of Strings under the hood. Also it doesn't loose events while reconfiguring.
Log4j 2 can log with higher speed than other frameworks I know: http://www.grobmeier.de/log4j-2-performance-close-to-insane-20072013.html
And still the user community seems to be much bigger than Logbacks: http://www.grobmeier.de/apache-log4j-is-the-leading-logging-framework-06082013.html
That all said the best idea is you choose the logging frameworks which just fits best to what you want to achieve. I would not switch a full framework if I would disable logging in production environment and just perform basic logging in my app. However if you do a bit more with logging just look at the features which are provided by the frameworks and their developers. While you get commercial support for Logback through QOS (i heard) there is currently no commercial support for Log4j 2. On the other hand if you need to do audit logging and need high performance provided by the async appenders it makes a lot of sense to check log4j 2.
Please note despite all comfort they provide, facades always eat a little performance. It's maybe not affecting you at all, but if you are on low resources you may need to save everything you can have.
Without knowing you requirements better it is almost impossible to give a recommendation. Just: don't switch just because a lot of people switch. Switch only because you see value of it. And the argumentation that log4j is dead doesn't count anymore. It's alive, and it's hot.
DISCLAIMER: I am currently VP, Apache Logging Services and involved in log4j as well.
From the docs
Bitcode will allow apple to optimise the app without you having to submit another build. But, you can only enable this feature if all frameworks and apps in the app bundle have this feature enabled. Having it helps, but not having it should not have any negative impact.
For iOS apps, bitcode is the default, but optional. If you provide bitcode, all apps and frameworks in the app bundle need to include bitcode. For watchOS apps, bitcode is required.
The App Store and operating system optimize the installation of iOS and watchOS apps by tailoring app delivery to the capabilities of the user’s particular device, with minimal footprint. This optimization, called app thinning, lets you create apps that use the most device features, occupy minimum disk space, and accommodate future updates that can be applied by Apple. Faster downloads and more space for other apps and content provides a better user experience.
There should not be any performance impacts.
I received the same error with RENAME USER
and GRANTS aren't covered by the currently accepted solution:
The most reliable way seems to be to run SHOW GRANTS
for the old user, find/replace what you want to change regarding the user's name and/or host and run them and then finally DROP USER
the old user. Not forgetting to run FLUSH PRIVILEGES
(best to run this after adding the new users' grants, test the new user, then drop the old user and flush again for good measure).

For those times when you need to use jquery to set !important properties, here is a plugin I build that will allow you to do so.
$.fn.important = function(key, value) {
var q = Object.assign({}, this.style)
q[key] = `${value} !important`;
$(this).css("cssText", Object.entries(q).filter(x => x[1]).map(([k, v]) => (`${k}: ${v}`)).join(';'));
};
$('div').important('color', 'red');
If you are ok with discarding nonconvertible characters, you can use -c
flag
iconv -c -t utf8 filename.csv > filename.utf8.csv
and then copy them to your table
If you click on child element of button, its better to use currentTarget to detect buttons attributes, in CH its sometimes problem to use e.target.
For the MVC4 app I am working on, I put a script element in _Layout.cshtml and created a global variable for the path required, like so:
<body>
<script>
var templatesPath = "@Url.Content("~/Templates/")";
</script>
<div class="page">
<div id="header">
<span id="title">
</span>
</div>
<div id="main">
@RenderBody()
</div>
<div id="footer">
<span></span>
</div>
</div>
Try out Following:
DataRow rows = DataTable.Select("[Name]<>'n/a'")
For Null check in This:
DataRow rows = DataTable.Select("[Name] <> 'n/a' OR [Name] is NULL" )
Your HTTP client disconnected.
This could have a couple of reasons:
You can fairly easily emulate the behavior:
URL url = new URL("http://example.com/path/to/the/file");
int numberOfBytesToRead = 200;
byte[] buffer = new byte[numberOfBytesToRead];
int numberOfBytesRead = url.openStream().read(buffer);
It works with just this:
.slideContainer {
white-space: nowrap;
}
.slide {
display: inline-block;
width: 600px;
white-space: normal;
}
I did originally have float : left;
and that prevented it from working correctly.
Thanks for posting this solution.
If you add:
jquery.form.min.js
You can simply do this:
<script>
$('#myform').ajaxForm(function(response) {
alert(response);
});
// this will register the AJAX for <form id="myform" action="some_url">
// and when you submit the form using <button type="submit"> or $('myform').submit(), then it will send your request and alert response
</script>
You could use simple $('FORM').serialize() as suggested in post above, but that will not work for FILE INPUTS... ajaxForm() will.
You are reinventing the wheel.
If you need persistence and other enterprise features use JMS (I'd suggest ActiveMq).
If you need fast in-memory queues use one of the impementations of java's Queue.
If you need to support java 1.4 or earlier, use Doug Lea's excellent concurrent package.
This is what I did. Works well.
First add the OkHttp to the gradle build file of the app module:
compile 'com.squareup.picasso:picasso:2.5.2'
compile 'com.squareup.okhttp3:okhttp:3.10.0'
compile 'com.jakewharton.picasso:picasso2-okhttp3-downloader:1.1.0'
Then make a class extending Application
import android.app.Application;
import com.jakewharton.picasso.OkHttp3Downloader;
import com.squareup.picasso.Picasso;
public class Global extends Application {
@Override
public void onCreate() {
super.onCreate();
Picasso.Builder builder = new Picasso.Builder(this);
builder.downloader(new OkHttp3Downloader(this,Integer.MAX_VALUE));
Picasso built = builder.build();
built.setIndicatorsEnabled(true);
built.setLoggingEnabled(true);
Picasso.setSingletonInstance(built);
}
}
add it to the Manifest file as follows :
<application
android:name=".Global"
.. >
</application>
Now use Picasso as you normally would. No changes.
EDIT:
if you want to use cached images only. Call the library like this. I've noticed that if we don't add the networkPolicy, images won't show up in an fully offline start even if they are cached. The code below solves the problem.
Picasso.with(this)
.load(url)
.networkPolicy(NetworkPolicy.OFFLINE)
.into(imageView);
EDIT #2
the problem with the above code is that if you clear cache, Picasso will keep looking for it offline in cache and fail, the following code example looks at the local cache, if not found offline, it goes online and replenishes the cache.
Picasso.with(getActivity())
.load(imageUrl)
.networkPolicy(NetworkPolicy.OFFLINE)
.into(imageView, new Callback() {
@Override
public void onSuccess() {
}
@Override
public void onError() {
//Try again online if cache failed
Picasso.with(getActivity())
.load(posts.get(position).getImageUrl())
.error(R.drawable.header)
.into(imageView, new Callback() {
@Override
public void onSuccess() {
}
@Override
public void onError() {
Log.v("Picasso","Could not fetch image");
}
});
}
});
Replace with
imageWidth = 1 * Convert.ToInt32(Label1.Text);
when you pass an object within curly braces as an argument to a function with one parameter , you're assigning this object to a variable which is the parameter in this case
You can use jQuery to make it easy and clear

var text = $(this).val();
var maxlength = $(this).attr("max");
if(text.length >= maxlength) {
return false;

This worked well for me:
mysqldump <DBNAME> --fields-terminated-by ',' \
--fields-enclosed-by '"' --fields-escaped-by '\' \
--no-create-info --tab /var/lib/mysql-files/
Or if you want to only dump a specific table:
mysqldump <DBNAME> <TABLENAME> --fields-terminated-by ',' \
--fields-enclosed-by '"' --fields-escaped-by '\' \
--no-create-info --tab /var/lib/mysql-files/
I'm dumping to /var/lib/mysql-files/
to avoid this error:
mysqldump: Got error: 1290: The MySQL server is running with the --secure-file-priv option so it cannot execute this statement when executing 'SELECT INTO OUTFILE'
This has the advantage of working on many flavors of unix ...and you can modify it trivially to work on any o/s. All of the solutions above give me compiler errors depending on the phase of the moon. The moment there's a good POSIX way to do it... don't use this (at the time this was written, that wasn't the case).
// ifconfig | perl -ne 'print "$1\n" if /inet addr:([\d.]+)/'
#include <stdlib.h>
int main() {
setenv("LANG","C",1);
FILE * fp = popen("ifconfig", "r");
if (fp) {
char *p=NULL, *e; size_t n;
while ((getline(&p, &n, fp) > 0) && p) {
if (p = strstr(p, "inet ")) {
p+=5;
if (p = strchr(p, ':')) {
++p;
if (e = strchr(p, ' ')) {
*e='\0';
printf("%s\n", p);
}
}
}
}
}
pclose(fp);
return 0;
}
DSO here means Dynamic Shared Object; since the error message says it's missing from the command line, I guess you have to add it to the command line.
That is, try adding -lpthread
to your command line.
I highly recommend you use the tobytes
function of the Image
object. After some timing checks this is much more efficient.
def jpg_image_to_array(image_path):
"""
Loads JPEG image into 3D Numpy array of shape
(width, height, channels)
"""
with Image.open(image_path) as image:
im_arr = np.fromstring(image.tobytes(), dtype=np.uint8)
im_arr = im_arr.reshape((image.size[1], image.size[0], 3))
return im_arr
The timings I ran on my laptop show
In [76]: %timeit np.fromstring(im.tobytes(), dtype=np.uint8)
1000 loops, best of 3: 230 µs per loop
In [77]: %timeit np.array(im.getdata(), dtype=np.uint8)
10 loops, best of 3: 114 ms per loop
```
Using an opacity setting of 99% (through the DXTransform filters) actually forces Internet Explorer to turn off ClearType, at least in Version 7. Source
Have you checked your folder structure? It seems to me like Express can't find your root directory, which should be a a folder named "site" right under your default directory. Here is how it should look like, according to the tutorial:
node_modules/
.bin/
express/
mongoose/
path/
site/
css/
img/
js/
index.html
package.json
For example on my machine, I started getting the same error as you when I renamed my "site" folder as something else. So I would suggest you check that you have the index.html page inside a "site" folder that sits on the same path as your server.js file.
Hope that helps!
You mean remote debug JBoss from Eclipse ?
From Configuring Eclipse for Remote Debugging:
Set the JAVA_OPTS variable as follows:
set JAVA_OPTS= -Xdebug -Xnoagent
-Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n %JAVA_OPTS%
or:
JAVA_OPTS="-Xdebug -Xnoagent
-Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n $JAVA_OPTS"
In the Debug frame, select the Remote Java Application node.
In the Connection Properties, specify localhost
as the Host and specify the Port as the port that was specified in the run batch script of the JBoss server, 8787
.
The selected answer is only for Safari. At the moment it's not possible to do real remote debugging in Chrome on iOS, but as with most mobile browsers you can use WeInRe for some simple debugging. It's a bit work to set up, but lets you inspect the DOM, see styling, change DOM and play with the console.
To setup:
npm install -g weinre
weinre --boundHost -all-
The bookmarklet is a bit more of an hassle to install. It's easiest if you have bookmark-sync turned on for both desktop and mobile Chrome. Copy the bookmarklet url from the local weinre server (same as above). Unfortunately it doesn't work because it's not url-encoded properly. So open the JavaScript console and type in:
copy(encodeURI('')); // paste bookmarklet inside quotes
You should now have the url-encoded bookmarklet in your clipboard. Paste it into a new bookmark under Mobile Bookmarks. Call it weinre or something simple to type. It should be synced to your mobile pretty fast, so load the page you want to inspect. Then type in the bookmark name in the url-bar, and you should see the bookmarklet as an auto-complete-suggestion. Click it to run bookmarklet code :)
adb kill-server
and adb start-server
only control the adb
daemon on the PC side. You need to restart adbd
daemon on the device itself after reverting the service.adb.root
property change done by adb root
:
~$ adb shell id
uid=2000(shell) gid=2000(shell)
~$ adb root
restarting adbd as root
~$ adb shell id
uid=0(root) gid=0(root)
~$ adb shell 'setprop service.adb.root 0; setprop ctl.restart adbd'
~$ adb shell id
uid=2000(shell) gid=2000(shell)
They are equivalent, from the standard (emphasis mine) (7.1.3.2):
A typedef-name can also be introduced by an alias-declaration. The identifier following the using keyword becomes a typedef-name and the optional attribute-specifier-seq following the identifier appertains to that typedef-name. It has the same semantics as if it were introduced by the typedef specifier. In particular, it does not define a new type and it shall not appear in the type-id.
Try this, works like charm, gives the date you have selected. onsubmit form try to get this value:-
var date = $("#scheduleDate").datepicker({ dateFormat: 'dd,MM,yyyy' }).val();
Just try the code below:
As I see you have inserted 'r+' or this command open the file in read mode so you are not able to write into it, so you have to open file in write mode 'w' if you want to overwrite the file contents and write new data, otherwise you can append data to file by using 'a'
I hope this will help ;)
f = open('testfile.txt', 'w')# just put 'w' if you want to write to the file
x = f.readlines() #this command will read file lines
y = int(x)+1
print y
z = str(y) #making data as string to avoid buffer error
f.write(z)
f.close()
a solution is using map
and filter
functions
python 2
d={"a":1,"b":2,"c":3}
l=("a","b","d")
map(d.__delitem__, filter(d.__contains__,l))
print(d)
python 3
d={"a":1,"b":2,"c":3}
l=("a","b","d")
list(map(d.__delitem__, filter(d.__contains__,l)))
print(d)
you get:
{'c': 3}
For at DataFrame one can simply type
head(data, num=10L)
to get the first 10 for example.
For a data.frame one can simply type
head(data, 10)
to get the first 10.
You can use Command prompt for VS 2010 and then select the path that your boost located. Use "bootstrap.bat", you can successfully install it.
Try this ,
<img src= "@Url.Content(Model.ImagePath)" alt="Sample Image" style="height:50px;width:100px;"/>
(or)
<img src="~/Content/img/@Url.Content(model =>model.ImagePath)" style="height:50px;width:100px;"/>
It's as simple as iterating the array and looking for the regexp
function searchStringInArray (str, strArray) {
for (var j=0; j<strArray.length; j++) {
if (strArray[j].match(str)) return j;
}
return -1;
}
Edit - make str
as an argument to function.
mysqldb
is a module for Python that doesn't come pre-installed or with Django. You can download mysqldb

I wrote a super simple delay function for an application I developed in Qt.
I would advise you to use this code rather than the sleep function as it won't let your GUI freeze.
Here is the code:
void delay()
{
QTime dieTime= QTime::currentTime().addSecs(1);
while (QTime::currentTime() < dieTime)
QCoreApplication::processEvents(QEventLoop::AllEvents, 100);
}
To delay an event by n seconds - use addSecs(n)
.
It is not possible to dynamically change the value of a file field, otherwise you could set it to "c:\yourfile" and steal files very easily.
However there are many solutions to a multi-upload system. I'm guessing that you're wanting to have a multi-select open dialog.
Perhaps have a look at http://www.plupload.com/ - it's a very flexible solution to multiple file uploads, and supports drop zones e.t.c.
If you press CTRL + I it will just format tabs/whitespaces in code and pressing CTRL + SHIFT + F format all code that is format tabs/whitespaces and also divide code lines in a way that it is visible without horizontal scroll.
Just had this problem where one person running Chrome (on a Mac) suddenly stopped loading the CSS file. CMD + R did NOT work at all. I don't like the suggestions above that force a permanent reload on the production system.
What worked was changing the name of the CSS file in the HTML file (and renaming the CSS file of course). This forced Chrome to go get the latest CSS file.
For anyone who came here looking for how to get the true accordion effect and only allow one row to be expanded at a time, you can add an event handler for show.bs.collapse like so:
$('.collapse').on('show.bs.collapse', function () {
$('.collapse.in').collapse('hide');
});
I modified this example to do so here: http://jsfiddle.net/QLfMU/116/
Use GET method if you want to retrieve the resources from URL. You could always see the last page if you hit the back button of your browser, and it could be bookmarked, so it is not as secure as POST method.
Use POST method if you want to 'submit' something to the URL. For example you want to create a google account and you may need to fill in all the detailed information, then you hit 'submit' button (POST method is called here), once you submit successfully, and try to hit back button of your browser, you will get error or a new blank form, instead of last page with filled form.
Use the dec argument to set ","

I'm facing same problem and so far I found:
new Uri(Request.Url,Request.ApplicationPath)
or
Request.Url.GetLeftPart(UriPartial.Authority)+Request.ApplicationPath
I have an easier solution (that I used myself recently, for a host of lazy reasons). Add this method to the class you are working in:
public static void DumbDebug(string message)
{
File.WriteAllText(@"C:\AdHocConsole\" + message + ".txt", "this is really dumb. I wish Microsoft had more obvious solutions to its solutions problems.");
}
Then...open up the directory AdHocConsole, and order by created time. Make sure when you add your 'print statements'. They are distinct though, else there will be juggling.

You should add AVD Emulator. Go to this location:

start AVD Manager and in the second tab(Device Definitions) click on the button "createAVD".
The easiest way that I found for adding a column to a DataFrame was to use the "add" function. Here's a snippet of code, also with the output to a CSV file. Note that including the "columns" argument allows you to set the name of the column (which happens to be the same as the name of the np.array that I used as the source of the data).
# now to create a PANDAS data frame
df = pd.DataFrame(data = FF_maxRSSBasal, columns=['FF_maxRSSBasal'])
# from here on, we use the trick of creating a new dataframe and then "add"ing it
df2 = pd.DataFrame(data = FF_maxRSSPrism, columns=['FF_maxRSSPrism'])
df = df.add( df2, fill_value=0 )
df2 = pd.DataFrame(data = FF_maxRSSPyramidal, columns=['FF_maxRSSPyramidal'])
df = df.add( df2, fill_value=0 )
df2 = pd.DataFrame(data = deltaFF_strainE22, columns=['deltaFF_strainE22'])
df = df.add( df2, fill_value=0 )
df2 = pd.DataFrame(data = scaled, columns=['scaled'])
df = df.add( df2, fill_value=0 )
df2 = pd.DataFrame(data = deltaFF_orientation, columns=['deltaFF_orientation'])
df = df.add( df2, fill_value=0 )
#print(df)
df.to_csv('FF_data_frame.csv')
Scaling horizontally ===> Thousands of minions will do the work together for you.

It's like lazy instantiation. If the variable is already defined it will take that value instead of creating the value again.
I got this exception while coping a object(variable) Matrix Array into Excel sheet. The solution to this is, Matrix array Index(i,j) must start from (0,0) whereas Excel sheet should start with Matrix Array index (i,j) from (1,1) .

}
Node left = node.getLeft();

The best code is no code at all:
The fundamental nature of coding is that our task, as programmers, is to recognize that every decision we make is a trade-off. […] Start with brevity. Increase the other dimensions as required by testing.
Consequently, less code is better code: Prefer ""
to string.Empty
or String.Empty
. Those two are six times longer with no added benefit — certainly no added clarity, as they express the exact same information.
When script execution is halted (e.g., on a breakpoint) you can simply view all globals in the right pane of the Developer Tools window:
Reason to that is with the new update, they changed the URL for the Android Developer Tools update site to require HTTPS. If you are updating ADT, make sure you use HTTPS in the URL for the Android Developer Tools update site.
It depends how easy you find the following, which uses simple String methods (in this case slice()
).
var str = "Hello World";_x000D_
str = str.slice(0, 3) + str.slice(4);_x000D_
console.log(str)
_x000D_
You can also use something like
<c:if test="${ testObject.testPropert == "testValue" }">...</c:if>
set the first element to NULL. printing the char array will give you nothing back.
sprintf(mystring, "%05d", myInt);
Here, "05" says "use 5 digits with leading zeros".
It's possible to toggle a class on hover strictly within a component's template, however, it's not a practical solution for obvious reasons. For prototyping on the other hand, I find it useful to not have to define data properties or event handlers within the script.

Your script is using too much memory. This can often happen in PHP if you have a loop that has run out of control and you are creating objects or adding to arrays on each pass of the loop.
Check for infinite loops.
If that isn't the problem, try and help out PHP by destroying objects that you are finished with by setting them to null. eg. $OldVar = null;
Check the code where the error actually happens as well. Would you expect that line to be allocating a massive amount of memory? If not, try and figure out what has gone wrong...
it's in <algorithm>
and called std::find
.
You could use this library: https://pypi.python.org/pypi/django-widget-tweaks
It allows you to do the following:
{% load widget_tweaks %}
<!-- add 2 extra css classes to field element -->
{{ form.title|add_class:"css_class_1 css_class_2" }}
You can also use the jquery prop() method for this.
$(function(){
$('yourselector').prop('target', '_blank');
});
if you want to give color code directly then use
textView.setTextColor(Color.parseColor("#ffffff"));
or if you want to give color code from colors folder then use
textView.setTextColor(R.color.white);
You can pass string parameters to JavaScript functions like below code:
I passed three parameters where the third one is a string parameter.
var btn ="<input type='button' onclick='RoomIsReadyFunc(" + ID + "," + RefId + ",\"" + YourString + "\");' value='Room is Ready' />";
// Your JavaScript function
function RoomIsReadyFunc(ID, RefId, YourString)
{
alert(ID);
alert(RefId);
alert(YourString);
}
You can skip the Performance counter check in the setup altogether:
setup.exe /ACTION=install /SKIPRULES=PerfMonCounterNotCorruptedCheck
I had the same problem exactly, and I can't remember how I fond this solution but simply adding DISTINCTROW
solved the problem.
In your code it will look like this:
UPDATE DISTINCTROW [GS] INNER JOIN [Views] ON <- the only change is here
([Views].Hostname = [GS].Hostname)
AND ([GS].APPID = [Views].APPID)
...
I'm not sure why this works, but for me, it did exactly what I needed.
Iterate over the list and compare the current closest number with abs(currentNumber - myNumber)
:
def takeClosest(myList, myNumber):
closest = myList[0]
for i in range(1, len(myList)):
if abs(i - myNumber) < closest:
closest = i
return closest
Time#localtime
will give you the time in the current time zone of the machine running the code:
> moment = Time.now.utc
=> 2011-03-14 15:15:58 UTC
> moment.localtime
=> 2011-03-14 08:15:58 -0700
Update: If you want to conver to specific time zones rather than your own timezone, you're on the right track. However, instead of worrying about EST vs EDT, just pass in the general Eastern Time zone -- it will know based on the day whether it is EDT or EST:
> Time.now.utc.in_time_zone("Eastern Time (US & Canada)")
=> Mon, 14 Mar 2011 11:21:05 EDT -04:00
> (Time.now.utc + 10.months).in_time_zone("Eastern Time (US & Canada)")
=> Sat, 14 Jan 2012 10:21:18 EST -05:00
You should initialize yours recordings. You are passing to adapter null
ArrayList<String> recordings = null; //You are passing this null
First you need to get rid of all newline characters in all your text nodes. Then you can use an identity transform to output your DOM tree. Look at the javadoc for TransformerFactory#newTransformer()
.
You can disable all security by editing /etc/my.cnf:

Again, even though this is an old question, it is very relevant! And I have found a simple way to normalise certain columns without the need of any packages:
normFunc <- function(x){(x-mean(x, na.rm = T))/sd(x, na.rm = T)}
For example
x<-rnorm(10,14,2)
y<-rnorm(10,7,3)
z<-rnorm(10,18,5)
df<-data.frame(x,y,z)
df[2:3] <- apply(df[2:3], 2, normFunc)
You will see that the y and z columns have been normalised. No packages needed :-)
Short one: No, it's not. You will have to work with images instead.
Simple way :
int a[]={6,2,5,1};
System.out.println(Arrays.toString(a));
int temp;
for(int i=0;i<a.length-1;i++){
for(int j=0;j<a.length-1;j++){
if(a[j] > a[j+1]){ // use < for Descending order
temp = a[j+1];
a[j+1] = a[j];
a[j]=temp;
}
}
}
System.out.println(Arrays.toString(a));
Output:
[6, 2, 5, 1]
[1, 2, 5, 6]
You should not start a container just to see the image contents. For instance, you might want to look for malicious content, not run it. Use "create" instead of "run";
docker create --name="tmp_$$" image:tag
docker export tmp_$$ | tar t
docker rm tmp_$$
In Sublime Text 3....Try changing the above code to this, note the addition of "start".....
"variants" : [
{ "name": "Run",
"cmd" : ["start", "${file_base_name}.exe"]
}
The other answers detail the reason for the error. A possible cause (to check) may be your class has a variable and method with the same name, which you then call. Python accesses the variable as a callable - with ()
.
e.g. Class A defines self.a
and self.a()
:
>>> class A:
... def __init__(self, val):
... self.a = val
... def a(self):
... return self.a
...
>>> my_a = A(12)
>>> val = my_a.a()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'int' object is not callable
>>>
The PHP way of doing this is simple:
$out = strlen($in) > 50 ? substr($in,0,50)."..." : $in;
But you can achieve a much nicer effect with this CSS:
.ellipsis {
overflow: hidden;
white-space: nowrap;
text-overflow: ellipsis;
}
Now, assuming the element has a fixed width, the browser will automatically break off and add the ...
for you.
Just run php --ini
and look for Loaded Configuration File
in output for the location of php.ini
used by your CLI
If you are on osx and using an emulator, you can view your console.log

I think you need to include the regex OR operator:
String[]tokens = pdfName.split("-|\\.");
What you have will match:
[DASH followed by DOT together] -.
not
[DASH or DOT any of them] -
or .

I hope this will help. I am using this formula for my Phase game.
The whole code if somebody need it.

You can try to host the analytics.js locally and update it's contents with a caching script or manually.
The js file is updated only few times a year and if you don't need any new tracking features update it manually.

Approach i used some years ago -
We need a jsp file , a servlet java file and a filter java file.
Give access of jsp file to user. User type url of jsp file .
Case 1 -
Using Printwriter , it will render the response to user .
Meanwhile, Servlet will create a key file .
When servlet try to execute the xxxx.js file within it , Filter
will activate and will detect key file exist and hence delete key
file .
Thus one cycle is over.
In short ,key file will created by server and will be immediatly deleted by filter .
This will happen upon every hit .
Case 2 -
Instead of File creation , one may use setting value in session variable .
why is it that even managed languages provide a finally-block despite resources being deallocated automatically by the garbage collector anyway?
Actually, languages based on Garbage collectors need "finally" more. A garbage collector does not destroy your objects in a timely manner, so it can not be relied upon to clean up non-memory related issues correctly.
In terms of dynamically-allocated data, many would argue that you should be using smart-pointers.
However...
RAII moves the responsibility of exception safety from the user of the object to the designer
Sadly this is its own downfall. Old C programming habits die hard. When you're using a library written in C or a very C style, RAII won't have been used. Short of re-writing the entire API front-end, that's just what you have to work with. Then the lack of "finally" really bites.
The class Date/Timestamp
represents a specific instant in time, with millisecond precision, since January 1, 1970, 00:00:00 GMT. So this time difference (from epoch to current time) will be same in all computers across the world with irrespective of Timezone.
Date/Timestamp
doesn't know about the given time is on which timezone.
If we want the time based on timezone we should go for the Calendar or SimpleDateFormat classes in java.
If you try to print a Date/Timestamp object using toString()
, it will convert and print the time with the default timezone of your machine.
So we can say (Date/Timestamp).getTime() object will always have UTC (time in milliseconds)
To conclude Date.getTime()
will give UTC time, but toString()
is on locale specific timezone, not UTC.
The below code gives you a date (time in milliseconds) with specified timezones. The only problem here is you have to give date in string format.
DateFormat dateFormat = new SimpleDateFormat("yyyyMMdd HH:mm:ss");
dateFormatLocal.setTimeZone(timeZone);
java.util.Date parsedDate = dateFormatLocal.parse(date);
Use dateFormat.format
for taking input Date (which is always UTC), timezone and return date as String.
If you print the parsedDate
object, the time will be in default timezone.
But you can store the UTC time in DB like below.
Calendar calGMT = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
Timestamp tsSchedStartTime = new Timestamp (parsedDate.getTime());
if (tsSchedStartTime != null) {
stmt.setTimestamp(11, tsSchedStartTime, calGMT );
} else {
stmt.setNull(11, java.sql.Types.DATE);
}
<input style="font-size:25px;" type="text"/>
The above code changes the font size to 25 pixels.
If you want to keep it simple go ahead and try this out.
$page_number = mysqli_escape_string($con, $_GET['page']);
$count_per_page = 20;
$next_offset = $page_number * $count_per_page;
$cat =mysqli_query($con, "SELECT * FROM categories LIMIT $count_per_page OFFSET $next_offset");
while ($row = mysqli_fetch_array($cat))
$count = $row[0];
The rest is up to you. If you have result comming from two tables i suggest you try a different approach.
For Android, and using Apache's Commons IO Library for IOUtils
:
// connection is a HttpURLConnection
InputStream inputStream = connection.getInputStream()
ByteArrayOutputStream baos = new ByteArrayOutputStream();
IOUtils.copy(inputStream, baos);
JSONObject jsonObject = new JSONObject(baos.toString()); // JSONObject is part of Android library
If you really need to do this, use reverse proxy.
For example, with nginx as reverse proxy
server {
listen api.mydomain.com:80;
server_name api.mydomain.com;
location / {
proxy_pass http://127.0.0.1:8000;
}
}
var d = new Date();
var n = d.getFullYear();
Yes, n will give you the 4 digit year, but you can always use substring or something similar to split up the year, thus giving you only two digits:
var final = n.toString().substring(2);
This will give you the last two digits of the year (2013 will become 13, etc...)
If there's a better way, hopefully someone posts it! This is the only way I can think of. Let us know if it works!
TL;DR: Use the utility method Iterables.size(Iterable)
of the great Guava library.
Of your two code snippets, you should use the first one, because the second one will remove all elements from values
, so it is empty afterwards. Changing a data structure for a simple query like its size is very unexpected.
For performance, this depends on your data structure. If it is for example in fact an ArrayList
, removing elements from the beginning (what your second method is doing) is very slow (calculating the size becomes O(n*n) instead of O(n) as it should be).
In general, if there is the chance that values
is actually a Collection
and not only an Iterable
, check this and call size()
in case:
if (values instanceof Collection<?>) {
return ((Collection<?>)values).size();
}
// use Iterator here...
The call to size()
will usually be much faster than counting the number of elements, and this trick is exactly what Iterables.size(Iterable)
of Guava does for you.
When I added the proxy info to the %JAVA_OPTS%, I got an error "-Dhttp.proxyHost=yourserver was unexpected at this time". I put the proxy info in %SBT_OPTS% and it worked.
when we call ASCII as 7 bit code, the left most bit is used as sign bit so with 7 bits we can write up to 127. that means from -126 to 127 because Max imam value of ASCII is 0 to 255. this can be only satisfied with the argument of 7 bit if last bit is considered as sign bit
This should work
Integer i= Integer.parseInt(text.substring(text.length() - 7));
I would like to augment to Stephen C's answer, my case was on the first dot. So since we have DHCP to allocate IP addresses in the company, DHCP changed my machine's address without of course asking neither me nor Oracle. So out of the blue oracle refused to do anything and gave the minus one dreaded exception. So if you want to workaround this once and for ever, and since TCP.INVITED_NODES of SQLNET.ora file does not accept wildcards as stated here, you can add you machine's hostname instead of the IP address.
if(jRadioButton1.isSelected()){
jTextField1.setText("Welcome");
}
else if(jRadioButton2.isSelected()){
jTextField1.setText("Hello");
}
You can try
ping -n XXX 127.0.0.1 >nul
where XXX is the number of seconds to wait, plus one.
The code below will work just fine in all browsers:
<button onClick="location.href = 'http://www.google.com'">Go to Google</button>
To complete @cpu-100 answer,
in case you don't want to enable/use web interface, you can create a new credentials using command line like below and use it in your code to connect to RabbitMQ.
$ rabbitmqctl add_user YOUR_USERNAME YOUR_PASSWORD
$ rabbitmqctl set_user_tags YOUR_USERNAME administrator
$ rabbitmqctl set_permissions -p / YOUR_USERNAME ".*" ".*" ".*"
This way you can Create NSArray, NSMutableArray.
NSArray keys =[NSArray arrayWithObjects:@"key1",@"key2",@"key3",nil];
NSArray objects =[NSArray arrayWithObjects:@"value1",@"value2",@"value3",nil];
Although the existing answers are valid approaches , they are antiquated . HttpClient is a modern interface for working with RESTful web services . Check the examples section of the page in the link , it has a very straightforward use case for an asynchronous HTTP GET .
using (var client = new System.Net.Http.HttpClient())
{
return await client.GetStringAsync("https://reqres.in/api/users/3"); //uri
}
Here is the formula
create a new rule in conditional formating based on a formula. Use the following formula and apply it to $A:$A
=NOT(ISERROR(MATCH(A1,$B$1:$B$1000,0)))
here is the example sheet to download if you encounter problems
UPDATE
here is @pnuts's suggestion which works perfect as well:
=MATCH(A1,B:B,0)>0
