You can read value by
searchTxt.value
function searchURL() {
let txt = searchTxt.value;
console.log(txt);
// window.location = "http://www.myurl.com/search/" + txt; ...
}
document.querySelector('.search').addEventListener("click", ()=>searchURL());
_x000D_
<input name="searchTxt" type="text" maxlength="512" id="searchTxt" class="searchField"/>
<button class="search">Search</button>
_x000D_
UPDATE
I see many downvotes but any comments - however (for future readers) actually this solution works
I faced this problem and when i started searching the important point i found is, the value u are looking up i.e M3 column should be present in the first column of the table u want to search https://support.office.com/en-us/article/VLOOKUP-function-0bbc8083-26fe-4963-8ab8-93a18ad188a1 check in lookup_value
Use "whereis" command.
$ whereis tomcat8
tomcat8: /usr/sbin/tomcat8 /etc/tomcat8 /usr/libexec/tomcat8 /usr/share/tomcat8
I think when you install python it puts export path statements into your ~/.bash_profile file. So if you do not intend to use Python 2 anymore you can just remove that statement from there. Alias as stated above is also a great way to do it.
Here is how to remove the reference from ~/.bash_profile - vim ./.bash_profile - remove the reference (AKA something like: export PATH="/Users/bla/anaconda:$PATH") - save and exit - source ./.bash_profile to save the changes
var compare = array1.length > array2.length ? array1 : array2;
var compareWith = array1.length > array2.length ? array2 : array1;
var uniqueValues = compareWith.filter(function(value){
if(compare.indexOf(vakye) == -1)
return true;
});
This will both check which one is the larger one among the arrays and then will do the comparison.
The first method is the proper approach and will do what you need. However, with the inner joins, you will only select rows from Table1
if both phone numbers exist in Table2
. You may want to do a LEFT JOIN
so that all rows from Table1
are selected. If the phone numbers don't match, then the SomeOtherField
s would be null. If you want to make sure you have at least one matching phone number you could then do WHERE t2.PhoneNumber IS NOT NULL OR t3.PhoneNumber IS NOT NULL
The second method could have a problem: what happens if Table2
has both PhoneNumber1
and PhoneNumber2
? Which row will be selected? Depending on your data, foreign keys, etc. this may or may not be a problem.
first ensure that your table storage engine type should be innoDB (you can set it using Table operations Tab)
if you are using new phpmyadmin then use new "Relation view" tab to make foreign key relation
if you are using old version of phpmyadmin then the "relation view" button will show on the bottom of the table columns

---Supplement:---
basically you can send multiple parameters this way:

console.log(response.Phone);
console.log(response.Email);
}
},
error: function (response) {
alert("error!");
}
});
This answer is all about authorization and it is a complement of my previous answer about authentication
Why another answer? I attempted to expand my previous answer by adding details on how to support JSR-250 annotations. However the original answer became the way too long and exceeded the maximum length of 30,000 characters. So I moved the whole authorization details to this answer, keeping the other answer focused on performing authentication and issuing tokens.
@Secured
annotationBesides authentication flow shown in the other answer, role-based authorization can be supported in the REST endpoints.
Create an enumeration and define the roles according to your needs:
public enum Role {
ROLE_1,
ROLE_2,
ROLE_3
}
Change the @Secured
name binding annotation created before to support roles:
@NameBinding
@Retention(RUNTIME)
@Target({TYPE, METHOD})
public @interface Secured {
Role[] value() default {};
}
And then annotate the resource classes and methods with @Secured
to perform the authorization. The method annotations will override the class annotations:
@Path("/example")
@Secured({Role.ROLE_1})
public class ExampleResource {
@GET
@Path("{id}")
@Produces(MediaType.APPLICATION_JSON)
public Response myMethod(@PathParam("id") Long id) {
// This method is not annotated with @Secured
// But it's declared within a class annotated with @Secured({Role.ROLE_1})
// So it only can be executed by the users who have the ROLE_1 role
...
}
@DELETE
@Path("{id}")
@Produces(MediaType.APPLICATION_JSON)
@Secured({Role.ROLE_1, Role.ROLE_2})
public Response myOtherMethod(@PathParam("id") Long id) {
// This method is annotated with @Secured({Role.ROLE_1, Role.ROLE_2})
// The method annotation overrides the class annotation
// So it only can be executed by the users who have the ROLE_1 or ROLE_2 roles
...
}
}
Create a filter with the AUTHORIZATION
priority, which is executed after the AUTHENTICATION
priority filter defined previously.
The ResourceInfo
can be used to get the resource Method
and resource Class
that will handle the request and then extract the @Secured
annotations from them:
@Secured
@Provider
@Priority(Priorities.AUTHORIZATION)
public class AuthorizationFilter implements ContainerRequestFilter {
@Context
private ResourceInfo resourceInfo;
@Override
public void filter(ContainerRequestContext requestContext) throws IOException {
// Get the resource class which matches with the requested URL
// Extract the roles declared by it
Class<?> resourceClass = resourceInfo.getResourceClass();
List<Role> classRoles = extractRoles(resourceClass);
// Get the resource method which matches with the requested URL
// Extract the roles declared by it
Method resourceMethod = resourceInfo.getResourceMethod();
List<Role> methodRoles = extractRoles(resourceMethod);
try {
// Check if the user is allowed to execute the method
// The method annotations override the class annotations
if (methodRoles.isEmpty()) {
checkPermissions(classRoles);
} else {
checkPermissions(methodRoles);
}
} catch (Exception e) {
requestContext.abortWith(
Response.status(Response.Status.FORBIDDEN).build());
}
}
// Extract the roles from the annotated element
private List<Role> extractRoles(AnnotatedElement annotatedElement) {
if (annotatedElement == null) {
return new ArrayList<Role>();
} else {
Secured secured = annotatedElement.getAnnotation(Secured.class);
if (secured == null) {
return new ArrayList<Role>();
} else {
Role[] allowedRoles = secured.value();
return Arrays.asList(allowedRoles);
}
}
}
private void checkPermissions(List<Role> allowedRoles) throws Exception {
// Check if the user contains one of the allowed roles
// Throw an Exception if the user has not permission to execute the method
}
}
If the user has no permission to execute the operation, the request is aborted with a 403
(Forbidden).
To know the user who is performing the request, see my previous answer. You can get it from the SecurityContext
(which should be already set in the ContainerRequestContext
) or inject it using CDI, depending on the approach you go for.
If a @Secured
annotation has no roles declared, you can assume all authenticated users can access that endpoint, disregarding the roles the users have.
Alternatively to defining the roles in the @Secured
annotation as shown above, you could consider JSR-250 annotations such as @RolesAllowed
, @PermitAll
and @DenyAll
.
JAX-RS doesn't support such annotations out-of-the-box, but it could be achieved with a filter. Here are a few considerations to keep in mind if you want to support all of them:
@DenyAll
on the method takes precedence over @RolesAllowed
and @PermitAll
on the class.@RolesAllowed
on the method takes precedence over @PermitAll
on the class.@PermitAll
on the method takes precedence over @RolesAllowed
on the class.@DenyAll
can't be attached to classes.@RolesAllowed
on the class takes precedence over @PermitAll
on the class.So an authorization filter that checks JSR-250 annotations could be like:
@Provider
@Priority(Priorities.AUTHORIZATION)
public class AuthorizationFilter implements ContainerRequestFilter {
@Context
private ResourceInfo resourceInfo;
@Override
public void filter(ContainerRequestContext requestContext) throws IOException {
Method method = resourceInfo.getResourceMethod();
// @DenyAll on the method takes precedence over @RolesAllowed and @PermitAll
if (method.isAnnotationPresent(DenyAll.class)) {
refuseRequest();
}
// @RolesAllowed on the method takes precedence over @PermitAll
RolesAllowed rolesAllowed = method.getAnnotation(RolesAllowed.class);
if (rolesAllowed != null) {
performAuthorization(rolesAllowed.value(), requestContext);
return;
}
// @PermitAll on the method takes precedence over @RolesAllowed on the class
if (method.isAnnotationPresent(PermitAll.class)) {
// Do nothing
return;
}
// @DenyAll can't be attached to classes
// @RolesAllowed on the class takes precedence over @PermitAll on the class
rolesAllowed =
resourceInfo.getResourceClass().getAnnotation(RolesAllowed.class);
if (rolesAllowed != null) {
performAuthorization(rolesAllowed.value(), requestContext);
}
// @PermitAll on the class
if (resourceInfo.getResourceClass().isAnnotationPresent(PermitAll.class)) {
// Do nothing
return;
}
// Authentication is required for non-annotated methods
if (!isAuthenticated(requestContext)) {
refuseRequest();
}
}
/**
* Perform authorization based on roles.
*
* @param rolesAllowed
* @param requestContext
*/
private void performAuthorization(String[] rolesAllowed,
ContainerRequestContext requestContext) {
if (rolesAllowed.length > 0 && !isAuthenticated(requestContext)) {
refuseRequest();
}
for (final String role : rolesAllowed) {
if (requestContext.getSecurityContext().isUserInRole(role)) {
return;
}
}
refuseRequest();
}
/**
* Check if the user is authenticated.
*
* @param requestContext
* @return
*/
private boolean isAuthenticated(final ContainerRequestContext requestContext) {
// Return true if the user is authenticated or false otherwise
// An implementation could be like:
// return requestContext.getSecurityContext().getUserPrincipal() != null;
}
/**
* Refuse the request.
*/
private void refuseRequest() {
throw new AccessDeniedException(
"You don't have permissions to perform this action.");
}
}
Note: The above implementation is based on the Jersey RolesAllowedDynamicFeature
. If you use Jersey, you don't need to write your own filter, just use the existing implementation.
This is not intended to be actually used in real life, just an interesting exercise. See Why is using the JavaScript eval function a bad idea? for details.
This is the closest you can get without resorting to vendor-specific extensions:
myArray = [1,2,3];
eval(set('a,b,c = myArray'));
Helper function:
function set(code) {
var vars=code.split('=')[0].trim().split(',');
var array=code.split('=')[1].trim();
return 'var '+vars.map(function(x,i){return x+'='+array+'['+i+']'}).join(',');
}
Proof that it works in arbitrary scope:
(function(){
myArray = [4,5,6];
eval(set('x,y,z = myArray'));
console.log(y); // prints 5
})()
eval
is not supported in Safari.
just a moment ago, i came across with the same issue. and i resolve it in the following manner.
Response.Redirect("../index.aspx?Name="+this.textName.Text+"&LastName="+this.textlName.Text);
with reference to the this
for me the shortest way is to type ./gradlew signingReport
in the terminal command line.
P.s : if you are in Windows use .\gradlew signingReport
instead.
Adding to @adardesign
's answer, if you want to reset all files that have been added to assume-unchanged
list to no-assume-unchanged
in one go, you can do the following:
git ls-files -v | grep '^h' | sed 's/^..//' | sed 's/\ /\\ /g' | xargs -I FILE git update-index --no-assume-unchanged FILE || true
This will just strip out the two characters output from grep i.e. "h "
, then escape any spaces that may be present in file names, and finally || true
will prevent the command to terminate prematurely in case some files in the loop has errors.
You can add a form onsubmit handler, something like:
<form onsubmit="return validate();">
</form>
<script>function validate() {
// check if input is bigger than 3
var value = document.getElementById('titleeee').value;
if (value.length < 3) {
return false; // keep form from submitting
}
// else form is good let it submit, of course you will
// probably want to alert the user WHAT went wrong.
return true;
}</script>
This is a FAQ:
4.1 Is it possible to locally disable a particular message?
Yes, this feature has been added in Pylint 0.11. This may be done by adding
# pylint: disable=some-message,another-one
at the desired block level or at the end of the desired line of code.4.2 Is there a way to disable a message for a particular module only?
Yes, you can disable or enable (globally disabled) messages at the module level by adding the corresponding option in a comment at the top of the file:
# pylint: disable=wildcard-import, method-hidden # pylint: enable=too-many-lines
You can disable messages by:
E1101
, E1102
, etc.no-member
, undefined-variable
, etc.pylint --list-groups
.C
, R
, W
, etc.all
.See the documentation (or run pylint --list-msgs
in the terminal) for the full list of Pylint's messages. The documentation also provide a nice example of how to use this feature.
Now you can use just window.scrollTo({ top: 0, behavior: 'smooth' })
to get the page scrolled with a smooth effect.
const btn = document.getElementById('elem');_x000D_
_x000D_
btn.addEventListener('click', () => window.scrollTo({_x000D_
top: 400,_x000D_

}
_x000D_
<div id='x'>_x000D_
<button id='elem'>Click to scroll</button>_x000D_
</div>
_x000D_
You can do something like this:
var btn = document.getElementById('x');_x000D_
_x000D_
btn.addEventListener("click", function() {_x000D_
var i = 10;_x000D_
var int = setInterval(function() {_x000D_
window.scrollTo(0, i);_x000D_
i += 10;_x000D_
if (i >= 200) clearInterval(int);_x000D_

From the MDN documentation:
[The margin property] applies to all elements except elements with table display types other than table-caption, table and inline-table
In other words, the margin
property is not applicable to display:table-cell
elements.
Consider using the border-spacing
property instead.
Note it should be applied to a parent element with a display:table
layout and border-collapse:separate
.
For example:
HTML
<div class="table">
<div class="row">
<div class="cell">123</div>
<div class="cell">456</div>
<div class="cell">879</div>
</div>
</div>
CSS
.table {display:table;border-collapse:separate;border-spacing:5px;}
.row {display:table-row;}
.cell {display:table-cell;padding:5px;border:1px solid black;}
Different margin horizontally and vertically
As mentioned by Diego QuirĂ³s, the border-spacing
property also accepts two values to set a different margin for the horizontal and vertical axes.
For example
.table {/*...*/border-spacing:3px 5px;} /* 3px horizontally, 5px vertically */
Just adding why and when to use Invoke().
Both Invoke() and BeginInvoke() marshal the code you specify to the dispatcher thread.
But unlike BeginInvoke(), Invoke() stalls your thread until the dispatcher executes your code. You might want to use Invoke() if you need to pause an asynchronous operation until the user has supplied some sort of feedback.
For example, you could call Invoke() to run a snippet of code that shows an OK/Cancel dialog box. After the user clicks a button and your marshaled code completes, the invoke() method will return, and you can act upon the user's response.

Your question is unclear. If you're asking how you can do this in a simpler way, you should take a look at the ECMAScript 5th edition method .bind(), which is a member of Function.prototype. Using it, you can do something like this:
function tryMe (param1, param2) {
alert (param1 + " and " + param2);
}
function callbackTester (callback) {
callback();
}
callbackTester(tryMe.bind(null, "hello", "goodbye"));
You can also use the following code, which adds the method if it isn't available in the current browser:
// From Prototype.js
if (!Function.prototype.bind) { // check if native implementation available
Function.prototype.bind = function(){
var fn = this, args = Array.prototype.slice.call(arguments),
object = args.shift();
return function(){
return fn.apply(object,
args.concat(Array.prototype.slice.call(arguments)));
};
};
}
There are quite a few projects that have settled on the Generic Graphics Toolkit for this. The GMTL in there is nice - it's quite small, very functional, and been used widely enough to be very reliable. OpenSG, VRJuggler, and other projects have all switched to using this instead of their own hand-rolled vertor/matrix math.
I've found it quite nice - it does everything via templates, so it's very flexible, and very fast.
Edit:
After the comments discussion, and edits, I thought I'd throw out some more information about the benefits and downsides to specific implementations, and why you might choose one over the other, given your situation.
GMTL -
Benefits: Simple API, specifically designed for graphics engines. Includes many primitive types geared towards rendering (such as planes, AABB, quatenrions with multiple interpolation, etc) that aren't in any other packages. Very low memory overhead, quite fast, easy to use.
Downsides: API is very focused specifically on rendering and graphics. Doesn't include general purpose (NxM) matrices, matrix decomposition and solving, etc, since these are outside the realm of traditional graphics/geometry applications.
Eigen -
Benefits: Clean API, fairly easy to use. Includes a Geometry module with quaternions and geometric transforms. Low memory overhead. Full, highly performant solving of large NxN matrices and other general purpose mathematical routines.
Downsides: May be a bit larger scope than you are wanting (?). Fewer geometric/rendering specific routines when compared to GMTL (ie: Euler angle definitions, etc).
IMSL -
Benefits: Very complete numeric library. Very, very fast (supposedly the fastest solver). By far the largest, most complete mathematical API. Commercially supported, mature, and stable.
Downsides: Cost - not inexpensive. Very few geometric/rendering specific methods, so you'll need to roll your own on top of their linear algebra classes.
NT2 -
Benefits: Provides syntax that is more familiar if you're used to MATLAB. Provides full decomposition and solving for large matrices, etc.
Downsides: Mathematical, not rendering focused. Probably not as performant as Eigen.
LAPACK -
Benefits: Very stable, proven algorithms. Been around for a long time. Complete matrix solving, etc. Many options for obscure mathematics.
Downsides: Not as highly performant in some cases. Ported from Fortran, with odd API for usage.
Personally, for me, it comes down to a single question - how are you planning to use this. If you're focus is just on rendering and graphics, I like Generic Graphics Toolkit, since it performs well, and supports many useful rendering operations out of the box without having to implement your own. If you need general purpose matrix solving (ie: SVD or LU decomposition of large matrices), I'd go with Eigen, since it handles that, provides some geometric operations, and is very performant with large matrix solutions. You may need to write more of your own graphics/geometric operations (on top of their matrices/vectors), but that's not horrible.
If you only need to only to disable updating updated_at just add this method to your model.
public function setUpdatedAtAttribute($value)
{
// to Disable updated_at
}
This will override the parent setUpdatedAtAttribute() method. created_at will work as usual. Same way you can write a method to disable updating created_at only.
You can execute commands in parallel with start
like this:
start "" ping myserver
start "" nslookup myserver
start "" morecommands
They will each start in their own command prompt and allow you to run multiple commands at the same time from one batch file.
Hope this helps!

To read a particular date from range EJ_PAYDATES_2021 (index is next to the last "1")
=INDEX(PayDates.xlsx!EJ_PAYDATES_2021,1,1) // Jan
=INDEX(PayDates.xlsx!EJ_PAYDATES_2021,2,1) // Feb
=INDEX(PayDates.xlsx!EJ_PAYDATES_2021,3,1) // Mar
This allows reading a particular element of a range [0] etc from another spreadsheet file. Target file need not be open. Range in the above example is named EJ_PAYDATES_2021, with one element for each month contained within that range.

Go to src folder of the project and copy all the code from it to some temporary location and build the project. And now copy the actual code from temporary location to project src. And run the build again. Problem will be resolved.
Note: This is specific to eclipse.
Both SAX and DOM are used to parse the XML document. Both has advantages and disadvantages and can be used in our programming depending on the situation
SAX:
Parses node by node
Does not store the XML in memory
We cant insert or delete a node
Top to bottom traversing
DOM
Stores the entire XML document into memory before processing
Occupies more memory
We can insert or delete nodes
Traverse in any direction.
If we need to find a node and does not need to insert or delete we can go with SAX itself otherwise DOM provided we have more memory.
Once you define a class (MyDTOClass) indicating what you expect to receive it should be as simple as...
public ActionResult Post([FromBody]MyDTOClass inputData){
... do something with input data ...
}

I found this solution via PowerShell :
dir | rename-item -NewName {$_.name -replace "replaceME","MyNewTxt"}
This will rename parts of all the files in the current folder.

Here I am giving you a proper example of one callback method . so suppose we have a method like method login() :
public void login() {
loginService = new LoginService();
loginService.login(loginProvider, new LoginListener() {
@Override
public void onLoginSuccess() {
loginService.getresult(true);
}
@Override
public void onLoginFaliure() {
loginService.getresult(false);
}
});
System.out.print("@@##### get called");
}
I also put all the helper class here to make the example more clear: loginService class
public class LoginService implements Login.getresult{
public void login(LoginProvider loginProvider,LoginListener callback){
String username = loginProvider.getUsername();
String pwd = loginProvider.getPassword();
if(username != null && pwd != null){
callback.onLoginSuccess();
}else{
callback.onLoginFaliure();
}
}
@Override
public void getresult(boolean value) {
System.out.print("login success"+value);
}}
and we have listener LoginListener as :
interface LoginListener {
void onLoginSuccess();
void onLoginFaliure();
}
now I just wanted to test the method login() of class Login
@Test
public void loginTest() throws Exception {
LoginService service = mock(LoginService.class);
LoginProvider provider = mock(LoginProvider.class);
whenNew(LoginProvider.class).withNoArguments().thenReturn(provider);
whenNew(LoginService.class).withNoArguments().thenReturn(service);
when(provider.getPassword()).thenReturn("pwd");
when(provider.getUsername()).thenReturn("username");
login.getLoginDetail("username","password");
verify(provider).setPassword("password");
verify(provider).setUsername("username");
verify(service).login(eq(provider),captor.capture());
LoginListener listener = captor.getValue();
listener.onLoginSuccess();
verify(service).getresult(true);
also dont forget to add annotation above the test class as
@RunWith(PowerMockRunner.class)
@PrepareForTest(Login.class)
A base R solution is to combine the output of aggregate()
with a merge()
step. I find the formula interface to aggregate()
a little more useful than the standard interface, partly because the names on the output are nicer, so I'll use that:
The aggregate()
step is
maxs <- aggregate(Score ~ Group, data = dat, FUN = max)
and the merge()
step is simply
merge(maxs, dat)
This gives us the desired output:
R> maxs <- aggregate(Score ~ Group, data = dat, FUN = max)
R> merge(maxs, dat)
Group Score Info
1 1 3 c
2 2 4 d
You could, of course, stick this into a one-liner (the intermediary step was more for exposition):
merge(aggregate(Score ~ Group, data = dat, FUN = max), dat)
The main reason I used the formula interface is that it returns a data frame with the correct names
for the merge step; these are the names of the columns from the original data set dat
. We need to have the output of aggregate()
have the correct names so that merge()
knows which columns in the original and aggregated data frames match.
The standard interface gives odd names, whichever way you call it:
R> aggregate(dat$Score, list(dat$Group), max)
Group.1 x
1 1 3
2 2 4
R> with(dat, aggregate(Score, list(Group), max))
Group.1 x
1 1 3
2 2 4
We can use merge()
on those outputs, but we need to do more work telling R which columns match up.
As described by Crist Clark.
CLOSE_WAIT means that the local end of the connection has received a FIN from the other end, but the OS is waiting for the program at the local end to actually close its connection.
The problem is your program running on the local machine is not closing the socket. It is not a TCP tuning issue. A connection can (and quite correctly) stay in CLOSE_WAIT forever while the program holds the connection open.
Once the local program closes the socket, the OS can send the FIN to the remote end which transitions you to LAST_ACK while you wait for the ACK of the FIN. Once that is received, the connection is finished and drops from the connection table (if your end is in CLOSE_WAIT you do not end up in the TIME_WAIT state).
I've used it to send intraday trades between different fund management systems. If you want to learn more about what a great technology messaging is, I can thoroughly recommend the book "Enterprise Integration Patterns". There are some JMS examples for things like request/reply and publish/subscribe.
Messaging is an excellent tool for integration.
Use round()
$float_val = 4.5;
echo round($float_val);
You can also set param for precision and rounding mode, for more info
Update (According to your updated question):
$float_val = 1.0000124668092E+14;
printf('%.0f', $float_val / 1E+14); //Output Rounds Of To 1000012466809201
No, this is not possible. However, one could do something like this:
List<Integer> temp = new ArrayList<Integer>();
temp.add(Integer.valueOf(0));
temp.add(Integer.valueOf(2));
temp.add(Integer.valueOf(3));
temp.add(Integer.valueOf(4));
List<Integer> immutable = Collections.unmodifiableList(temp);
This requires using wrappers, and is a List, not an array, but is the closest you will get.
For Writing Excel
For Reading Excel
A new C++ Excel extension for PHP, though you'll need to build it yourself, and the docs are pretty sparse when it comes to trying to find out what functionality (I can't even find out from the site what formats it supports, or whether it reads or writes or both.... I'm guessing both) it offers is phpexcellib from SIMITGROUP.
All claim to be faster than PHPExcel from codeplex or from github, but (with the exception of COM, PUNO Ilia's wrapper around libXl and spout) they don't offer both reading and writing, or both xls and xlsx; may no longer be supported; and (while I haven't tested Ilia's extension) only COM and PUNO offers the same degree of control over the created workbook.
<div ng-repeat="file in files" ng-class="!$last ? 'class-for-last' : 'other'">
{{file.name}}
</div>
That works for me! Good luck!
As for the people who are still visiting this page, you are only allowed to close a tab that is opened by a script OR by using the anchor tag of HTML with target _blank. Both those can be closed using the
<script>
window.close();
</script>
You can use bootstrap flex class name like that:
<div class="d-flex justify-content-center">
// the elements you want to center
</div>
That will work even with number of elements inside.
scale(..)
works a bit differently. You can use bufferedImage.getScaledInstance(..)
Just use a compiler (or provide it with the arguments it needs) such that it compiles for a more recent version of the C standard, C99 or C11. E.g for the GCC family of compilers that would be -std=c99
.
It's also possible to specify the ForeignKey()
attribute on the navigation property:
[ForeignKey("HomeTeamID")]
public virtual Team HomeTeam { get; set; }
[ForeignKey("GuestTeamID")]
public virtual Team GuestTeam { get; set; }
That way you don't need to add any code to the OnModelCreate
method
If the message is "n commits behind master."
You need to rebase your dev branch with master. You got the above message because after checking out dev branch from master, the master branch got new commit and has moved ahead. You need to get those new commits to your dev branch.
Steps:
git checkout master
git pull #this will update your local master
git checkout yourDevBranch
git rebase master
From the psql

First, choose your database
\c database_name
Then, this shows all tables in the current schema:

The system tables live in the pg_catalog
database.

As @weichsel stated, CGFloat is just a typedef for either float
or double
. You can see for yourself by Command-double-clicking on "CGFloat" in Xcode — it will jump to the CGBase.h header where the typedef is defined. The same approach is used for NSInteger and NSUInteger as well.
These types were introduced to make it easier to write code that works on both 32-bit and 64-bit without modification. However, if all you need is float
precision within your own code, you can still use float
if you like — it will reduce your memory footprint somewhat. Same goes for integer values.
I suggest you invest the modest time required to make your app 64-bit clean and try running it as such, since most Macs now have 64-bit CPUs and Snow Leopard is fully 64-bit, including the kernel and user applications. Apple's 64-bit Transition Guide for Cocoa is a useful resource.
import matplotlib.pyplot as plt

If you use this, you won’t get that error, and it is the simplest way to do that.
I know it's late and was answered, but I'd like to share the neat stuff I made. I created an ng-validate directive that hooks the onsubmit of the form, then it issues prevent-default if the $eval is false:
app.directive('ngValidate', function() {
return function(scope, element, attrs) {
if (!element.is('form'))
throw new Error("ng-validate must be set on a form elment!");
element.bind("submit", function(event) {
if (!scope.$eval(attrs.ngValidate, {'$event': event}))
event.preventDefault();
if (!scope.$$phase)
scope.$digest();
});
};
});
In your html:
<form name="offering" method="post" action="offer" ng-validate="<boolean expression">
Here a another solution with "rename" command:
find -name 'access.log.*.gz' | sort -Vr | rename 's/(\d+)/$1+1/ge'

Include the HTML
Including HTML is done by using a w3-include-html attribute:
Example
<div w3-include-html="content.html"></div>
Add the JavaScript
HTML includes are done by JavaScript.
<script>
function includeHTML() {
var z, i, elmnt, file, xhttp;
/*loop through a collection of all HTML elements:*/
z = document.getElementsByTagName("*");
for (i = 0; i < z.length; i++) {
elmnt = z[i];
/*search for elements with a certain atrribute:*/
file = elmnt.getAttribute("w3-include-html");
if (file) {
/*make an HTTP request using the attribute value as the file name:*/
xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4) {
if (this.status == 200) {elmnt.innerHTML = this.responseText;}
if (this.status == 404) {elmnt.innerHTML = "Page not found.";}
/*remove the attribute, and call this function once more:*/
elmnt.removeAttribute("w3-include-html");
includeHTML();
}
}
xhttp.open("GET", file, true);
xhttp.send();
/*exit the function:*/
return;
}
}
}
</script>
Call includeHTML() at the bottom of the page:
Example
<!DOCTYPE html>
<html>
<script>
function includeHTML() {
var z, i, elmnt, file, xhttp;
/*loop through a collection of all HTML elements:*/
z = document.getElementsByTagName("*");
for (i = 0; i < z.length; i++) {
elmnt = z[i];
/*search for elements with a certain atrribute:*/
file = elmnt.getAttribute("w3-include-html");
if (file) {
/*make an HTTP request using the attribute value as the file name:*/
xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4) {
if (this.status == 200) {elmnt.innerHTML = this.responseText;}
if (this.status == 404) {elmnt.innerHTML = "Page not found.";}
/*remove the attribute, and call this function once more:*/
elmnt.removeAttribute("w3-include-html");
includeHTML();
}
}
xhttp.open("GET", file, true);
xhttp.send();
/*exit the function:*/
return;
}
}
};
</script>

$str='This is a Text \n and so on Text text.';

Using .split()
. (Second version uses .slice()
and .join()
on the Array.)
var result = name.split('name')[1];
var result = name.split('name').slice( 1 ).join(''); // May be a little safer
Using .replace()
.
var result = name.replace('name','');
Using .slice()
on a String.
var result = name.slice( 4 );
You almost had it, just need to escape special regex chars:
regex = /http\:\/\/www\.youtube\.com\/watch\?v=([\w-]{11})/;
url = 'http://www.youtube.com/watch?v=Ahg6qcgoay4';
id = url.match(regex)[1]; // id = 'Ahg6qcgoay4'
Edit: Fix for regex by soupagain.
(1) Use str.isalpha() when you print the string.
(2) Please check below program for your reference:-
str = "this"; # No space & digit in this string
print str.isalpha() # it gives return True
str = "this is 2";
print str.isalpha() # it gives return False
Note:- I checked above example in Ubuntu.
You need to use the doubleValue()
method to get the double value from a BigDecimal object.
BigDecimal bd; // the value you get
double d = bd.doubleValue(); // The double you want
h.inject({}) { |m, (k,v)| m[k.sub(/^_/,'')] = v; m }
Easy, as long as your filenames don't include newlines:
find . -maxdepth 1
If you're piping this into another command, you should probably prefer to separate your filenames by null bytes, rather than newlines, since null bytes cannot occur in a filename (but newlines may):
find . -maxdepth 1 -print0
Printing that on a terminal will probably display as one line, because null bytes are not normally printed. Some programs may need a specific option to handle null-delimited input, such as sort
's -z
. Your own script similarly would need to account for this.
to fix this, I had to change permissions for whole directory to 755 (777 did not work for me), and changed file owners for whole directory
chmod -R 755 public_html
chown -R nobody:nobody public_html
nobody is user that runs php in my computer.
If you wanna actually just create remote branch without having the local one, you can do it like this:
git push origin HEAD:refs/heads/foo
It pushes whatever is your HEAD to branch foo that did not exist on the remote.
There is an option in WinSCP that does exactly what you are looking for:
Here is the actual code for what's described above as the "the safest 'correct' method"...
function reduce_query($uri = '') {
$kill_params = array('gclid');
$uri_array = parse_url($uri);
if (isset($uri_array['query'])) {
// Do the chopping.
$params = array();
foreach (explode('&', $uri_array['query']) as $param) {
$item = explode('=', $param);
if (!in_array($item[0], $kill_params)) {
$params[$item[0]] = isset($item[1]) ? $item[1] : '';
}
}
// Sort the parameter array to maximize cache hits.
ksort($params);
// Build new URL (no hosts, domains, or fragments involved).
$new_uri = '';
if ($uri_array['path']) {
$new_uri = $uri_array['path'];
}
if (count($params) > 0) {
// Wish there was a more elegant option.
$new_uri .= '?' . urldecode(http_build_query($params));
}
return $new_uri;
}
return $uri;
}
$_SERVER['REQUEST_URI'] = reduce_query($_SERVER['REQUEST_URI']);
However, since this will likely exist prior to the bootstrap of your application, you should probably put it into an anonymous function. Like this...
call_user_func(function($uri) {
$kill_params = array('gclid');
$uri_array = parse_url($uri);
if (isset($uri_array['query'])) {
// Do the chopping.
$params = array();
foreach (explode('&', $uri_array['query']) as $param) {
$item = explode('=', $param);
if (!in_array($item[0], $kill_params)) {
$params[$item[0]] = isset($item[1]) ? $item[1] : '';
}
}
// Sort the parameter array to maximize cache hits.
ksort($params);
// Build new URL (no hosts, domains, or fragments involved).
$new_uri = '';
if ($uri_array['path']) {
$new_uri = $uri_array['path'];
}
if (count($params) > 0) {
// Wish there was a more elegant option.
$new_uri .= '?' . urldecode(http_build_query($params));
}
// Update server variable.
$_SERVER['REQUEST_URI'] = $new_uri;
}
}, $_SERVER['REQUEST_URI']);
NOTE: Updated with urldecode()
to avoid double encoding via http_build_query()
function.
NOTE: Updated with ksort()
to allow params with no value without an error.
If the problem is with the index as the staging area for commits (i.e. .git/index
), you can simply remove the index (make a backup copy if you want), and then restore index to version in the last commit:
On OSX/Linux:
rm -f .git/index
git reset
On Windows:
del .git\index
git reset
(The reset
command above is the same as git reset --mixed HEAD
)
You can alternatively use lower level plumbing git read-tree
instead of git reset
.
If the problem is with index for packfile, you can recover it using git index-pack
.
I had this issue when I was trying to reinstall Android Studio through its wizard. I already had a "tools" folder though.
In my case, while the "tools" directory already existed, it will deliver the "sdk tools directory is missing" error for its subfolders also. Somehow my sdk folder only had a libs subdirectory.
When I pasted in sdk/ant, sdk/apps, sdk/proguard, sdk/qemu, sdk/support, and sdk/templates the wizard was finally happy with this configuration and went to download some more files.
On Mac OS X Yosemite just install:
Java SE Development Kit 8
and
Java Version 8 Update 25
It's all, work for me too! like gehev said , so simple !
Under the covers there will be some form of URL loading request. You can't load images or any other content via this method from a local file system.
Your image needs to be loaded via a web server, so accessed via a proper http URL.
The PictureBox.Load(string url) method "sets the ImageLocation to the specified URL and displays the image indicated."
FWIW, here is my approach = a simple one that works for me:
<div id="outerDivWrapper">
<div id="outerDiv">
<div id="scrollableContent">
blah blah blah
</div>
</div>
</div>
html, body {
height: 100%;
margin: 0em;
}
#outerDivWrapper, #outerDiv {
height: 100%;
margin: 0em;
}
#scrollableContent {
height: 100%;
margin: 0em;
overflow-y: auto;
}
I got the same error but when using tensorboard:
Fatal error in launcher: Unable to create process using '"'
I found out that the problem was caused by existing two copies of tensotboard.exe in two different directories and both directories were added to the path:
C:\Program Files\Python36\Scripts
and
C:\Users\...\AppData\Local\Programs\Python\Python36\Scripts
I removed the first one from the path and it fixed the problem.
there is the simple reason behind it that is because object is not required to call static method , if It were non-static method, java virtual machine creates object first then call main() method that will lead to the problem of extra memory allocation.
The .browser call has been removed in jquery 1.9 have a look at http://jquery.com/upgrade-guide/1.9/ for more details.
Many things have been changed in last 6 years on multi-threading front.
Instead of using join()
and lock API, you can use
1.ExecutorService invokeAll()
API
Executes the given tasks, returning a list of Futures holding their status and results when all complete.
A synchronization aid that allows one or more threads to wait until a set of operations being performed in other threads completes.
A
CountDownLatch
is initialized with a given count. The await methods block until the current count reaches zero due to invocations of thecountDown()
method, after which all waiting threads are released and any subsequent invocations of await return immediately. This is a one-shot phenomenon -- the count cannot be reset. If you need a version that resets the count, consider using a CyclicBarrier.
3.ForkJoinPool or newWorkStealingPool()
in Executors is other way
4.Iterate through all Future
tasks from submit on ExecutorService
and check the status with blocking call get()
on Future
object
Have a look at related SE questions:
How to wait for a thread that spawns it's own thread?
Executors: How to synchronously wait until all tasks have finished if tasks are created recursively?
Check and make sure that you do not have another values folder that references theme.styled and does not use AppCompat theme
ie values-v11
folder
This behavior is related to Zone that is set - Internet/Intranet/etc and corresponding Security Level
You can change this by setting less secure Security Level (not recommended) or by customizing Display Mixed Content property
You can do that by following steps:
var arr = [
{
"id": "1",
"msg": "hi",
"tid": "2013-05-05 23:35",
"fromWho": "[email protected]"
}, {
"id": "2",
"msg": "there",
"tid": "2013-05-05 23:45",
"fromWho": "[email protected]"
}
];
forEach method for easy implementation.
arr.forEach(function(item){
console.log('ID: ' + item.id);
console.log('MSG: ' + item.msg);
console.log('TID: ' + item.tid);
console.log('FROMWHO: ' + item.fromWho);
});
I had this same error in python 3.2.

what about something like this:
if(count($types_of_values)>0){
$uid = 1;
$x = 0;
$sql = "";
$values = array();
foreach($types_of_values as $k=>$v){
$sql .= "(:id_$k,:kind_of_val_$k), ";
$values[":id_$k"] = $uid;
$values[":kind_of_val_$k"] = $v;
}
$sql = substr($sql,0,-2);
$query = "INSERT INTO table (id,value_type) VALUES $sql";
$res = $this->db->prepare($query);
$res->execute($values);
}
The idea behind this is to cycle through your array values, adding "id numbers" to each loop for your prepared statement placeholders while at the same time, you add the values to your array for the binding parameters. If you don't like using the "key" index from the array, you could add $i=0, and $i++ inside the loop. Either works in this example, even if you have associative arrays with named keys, it would still work providing the keys were unique. With a little work it would be fine for nested arrays too..
**Note that substr strips the $sql variables last space and comma, if you don't have a space you'd need to change this to -1 rather than -2.
Why don't you examine System.getProperty("os.arch")
value in your code?
Here is a polyglot program for BASH and Windows CMD that runs a series of commands and quits out if any of them fail:

command 2 || goto :error
command 3 || goto :error
:; exit 0
exit /b 0

I have used this type of thing in the past for a multiple platform continuous integration script.
$('.submit').filter(':checked').each(function() {
//This is same as 'continue'
if(something){
return true;
}
//This is same as 'break'
if(something){

});
You need to print a new line after each row... System.out.print("\n")
, or use println
, etc. As it stands you are just printing nothing - System.out.print("")
, replace print
with println
or ""
with "\n"
.
This is how to pass the struct
by reference. This means that your function can access the struct
outside of the function and modify its values. You do this by passing a pointer to the structure to the function.
#include <stdio.h>
/* card structure definition */
struct card
{
int face; // define pointer face
}; // end structure card
typedef struct card Card ;
/* prototype */
void passByReference(Card *c) ;
int main(void)
{
Card c ;
c.face = 1 ;
Card *cptr = &c ; // pointer to Card c
printf("The value of c before function passing = %d\n", c.face);
printf("The value of cptr before function = %d\n",cptr->face);
passByReference(cptr);
printf("The value of c after function passing = %d\n", c.face);
return 0 ; // successfully ran program
}
void passByReference(Card *c)
{
c->face = 4;
}
This is how you pass the struct
by value so that your function receives a copy of the struct
and cannot access the exterior structure to modify it. By exterior I mean outside the function.
#include <stdio.h>
/* global card structure definition */
struct card
{
int face ; // define pointer face
};// end structure card
typedef struct card Card ;
/* function prototypes */
void passByValue(Card c);
int main(void)
{
Card c ;
c.face = 1;
printf("c.face before passByValue() = %d\n", c.face);
passByValue(c);
printf("c.face after passByValue() = %d\n",c.face);
printf("As you can see the value of c did not change\n");
printf("\nand the Card c inside the function has been destroyed"
"\n(no longer in memory)");
}
void passByValue(Card c)
{
c.face = 5;
}

System.out.println(integers1.length); //it has length 10 but it is empty. It is not null array
for (Integer integer : integers1) {
System.out.println(integer); //prints all 0s

//But if I manually add 0 to any index, now even though array has all 0s elements
//still it is not empty
// integers1[2] = 0;
for (Integer integer : integers1) {
System.out.println(integer); //Still it prints all 0s but it is not empty
//but that manually added 0 is different
}
//Even we manually add 0, still we need to treat it as null. This is semantic logic.
Integer[] integers2 = new Integer[20];
integers2 = null; //array is nullified
// integers2[3] = null; //If I had int[] -- because it is priitive -- then I can't write this line.
if (integers2 == null) {

Whenever you use NULL you are really dealing with a Three-Valued logic.
Your first query returns results as the WHERE clause evaluates to:
3 = 1 or 3 = 2 or 3 = 3 or 3 = null
which is:
FALSE or FALSE or TRUE or UNKNOWN
which evaluates to
TRUE
The second one:
3 <> 1 and 3 <> 2 and 3 <> null
which evaluates to:
TRUE and TRUE and UNKNOWN
which evaluates to:
UNKNOWN
The UNKNOWN is not the same as FALSE you can easily test it by calling:
select 'true' where 3 <> null
select 'true' where not (3 <> null)
Both queries will give you no results
If the UNKNOWN was the same as FALSE then assuming that the first query would give you FALSE the second would have to evaluate to TRUE as it would have been the same as NOT(FALSE).
That is not the case.
There is a very good article on this subject on SqlServerCentral.
The whole issue of NULLs and Three-Valued Logic can be a bit confusing at first but it is essential to understand in order to write correct queries in TSQL
Another article I would recommend is SQL Aggregate Functions and NULL.
There are several possible answers here. You want to return something that might exist. Here are some options, ranging from my least preferred to most preferred:
Return by reference, and signal can-not-find by exception.
Attr& getAttribute(const string& attribute_name) const
{
//search collection
//if found at i
return attributes[i];
//if not found
throw no_such_attribute_error;
}
It's likely that not finding attributes is a normal part of execution, and hence not very exceptional. The handling for this would be noisy. A null value cannot be returned because it's undefined behaviour to have null references.
Return by pointer
Attr* getAttribute(const string& attribute_name) const
{
//search collection
//if found at i
return &attributes[i];
//if not found
return nullptr;
}
It's easy to forget to check whether a result from getAttribute would be a non-NULL pointer, and is an easy source of bugs.
Use Boost.Optional
boost::optional<Attr&> getAttribute(const string& attribute_name) const
{
//search collection
//if found at i
return attributes[i];
//if not found
return boost::optional<Attr&>();
}
A boost::optional signifies exactly what is going on here, and has easy methods for inspecting whether such an attribute was found.
Side note: std::optional was recently voted into C++17, so this will be a "standard" thing in the near future.
I did some research on this by using different methods to assign values to a nullable int. Here is what happened when I did various things. Should clarify what's going on.
Keep in mind: Nullable<something>
or the shorthand something?
is a struct for which the compiler seems to be doing a lot of work to let us use with null as if it were a class.
As you'll see below, SomeNullable == null
and SomeNullable.HasValue
will always return an expected true or false. Although not demonstrated below, SomeNullable == 3
is valid too (assuming SomeNullable is an int?
).
While SomeNullable.Value
gets us a runtime error if we assigned null
to SomeNullable
. This is in fact the only case where nullables could cause us a problem, thanks to a combination of overloaded operators, overloaded object.Equals(obj)
method, and compiler optimization and monkey business.
Here is a description of some code I ran, and what output it produced in labels:
int? val = null;
lbl_Val.Text = val.ToString(); //Produced an empty string.
lbl_ValVal.Text = val.Value.ToString(); //Produced a runtime error. ("Nullable object must have a value.")
lbl_ValEqNull.Text = (val == null).ToString(); //Produced "True" (without the quotes)
lbl_ValNEqNull.Text = (val != null).ToString(); //Produced "False"
lbl_ValHasVal.Text = val.HasValue.ToString(); //Produced "False"
lbl_NValHasVal.Text = (!(val.HasValue)).ToString(); //Produced "True"
lbl_ValValEqNull.Text = (val.Value == null).ToString(); //Produced a runtime error. ("Nullable object must have a value.")
lbl_ValValNEqNull.Text = (val.Value != null).ToString(); //Produced a runtime error. ("Nullable object must have a value.")
Ok, lets try the next initialization method:
int? val = new int?();
lbl_Val.Text = val.ToString(); //Produced an empty string.
lbl_ValVal.Text = val.Value.ToString(); //Produced a runtime error. ("Nullable object must have a value.")
lbl_ValEqNull.Text = (val == null).ToString(); //Produced "True" (without the quotes)
lbl_ValNEqNull.Text = (val != null).ToString(); //Produced "False"
lbl_ValHasVal.Text = val.HasValue.ToString(); //Produced "False"
lbl_NValHasVal.Text = (!(val.HasValue)).ToString(); //Produced "True"
lbl_ValValEqNull.Text = (val.Value == null).ToString(); //Produced a runtime error. ("Nullable object must have a value.")
lbl_ValValNEqNull.Text = (val.Value != null).ToString(); //Produced a runtime error. ("Nullable object must have a value.")
All the same as before. Keep in mind that initializing with int? val = new int?(null);
, with null passed to the constructor, would have produced a COMPILE time error, since the nullable object's VALUE is NOT nullable. It is only the wrapper object itself that can equal null.
Likewise, we would get a compile time error from:
int? val = new int?();
val.Value = null;
not to mention that val.Value
is a read-only property anyway, meaning we can't even use something like:
val.Value = 3;
but again, polymorphous overloaded implicit conversion operators let us do:
val = 3;
No need to worry about polysomthing whatchamacallits though, so long as it works right? :)
Here's the working version of the code in question (requires at least version Matplotlib 1.1.0 from 2011-11-14):
import numpy as np
import matplotlib.pyplot as plt
plt.axis([0, 10, 0, 1])
for i in range(10):
y = np.random.random()
plt.scatter(i, y)
plt.pause(0.05)
plt.show()
Note some of the changes:
plt.pause(0.05)
to both draw the new data and it runs the GUI's event loop (allowing for mouse interaction).In my case none of previous solutions was good. Instead of using socket, you can use TCP host
+ port
number in Rails config file. So in database.yml
file just add two lines like here:
...
adapter: postgresql
encoding: unicode
pool: 5
host: localhost
port: 5432
This solved my problem :)
Before I used this fix:
sudo mkdir /var/run/postgresql
sudo ln -s /tmp/.s.PGSQL.5432 /var/run/postgresql/.s.PGSQL.5432
But after each reboot /tmp/.s.PGSQL.5432
was deleted and I had to repeat these commands. Solution works, but it is horrible, so better just modify Rails database config file :)
In handlebar version 3.0 onwards,
{{#each users as |user userId|}}
Id: {{userId}} Name: {{user.name}}
{{/each}}
In this particular example, user will have the same value as the current context and userId will have the index value for the iteration. Refer - http://handlebarsjs.com/block_helpers.html in block helpers section
The best way to solve this is to use Vanilla JS, but if you are already using jQuery, there´s a very easy solution:
<script type="text/javascript">
function doOnClick() {
$('#linkid').click();
}
</script>
<a id="linkid" href="/testlocation" onclick="alert(this.href);">Testlink</a>
Tested in IE8-10, Chrome, Firefox.
You could use a function like this:
var toObject = function(array) {
var o = {};
for (var property in array) {
if (String(property >>> 0) == property && property >>> 0 != 0xffffffff) {
o[i] = array[i];
}
}
return o;
};
This one should handle sparse arrays more efficiently.

And press button Commit changes is the last step.
I prefer feature before layers, but I guess it depends on you project. Consider your forces:
Example:
com/company/module
+ feature1/
- MainClass // The entry point for exploring
+ api/ // Public interface, used by other features
+ domain/
- AggregateRoot
+ api/ // Internal API, complements the public, used by web
+ impl/
+ persistence/
+ web/ // presentation layer
+ services/ // Rest or other remote API
+ support/
+ feature2/
+ support/ // Any support or utils used by more than on feature
+ io
+ config
+ persistence
+ web
This is just an example. It is quite formal. For example it defines 2 interfaces for feature1. Normally that is not required, but could be a good idea if used differently by different people. You may let the internal API extend the public.
I do not like the 'impl' or 'support' names, but they help separate the less important stuff from the important (domain and API). When it comes to naming I like to be as concrete as possible. If you have a package called 'utils' with 20 classes, move StringUtils
to support/string, HttpUtil
to support/http and so on.
I got the answer:(It's simple )
Take a ArrayList then cast it and find the size of the arraylist. Here it is :
ArrayList count = new ArrayList();
count=(ArrayList) maptabcolname.get("k1"); //here "k1" is Key
System.out.println("number of elements="+count.size());
It will show the size. (Give suggestion). It's working.
This can be achieved as follows:
this.itemArr = this.itemArr.filter( h => h.id !== ID);
Your original example works just fine for me:
<html>
<head>
</head>
<body>
<script>
var widthRange = new Array();
widthRange[46] = { sel:46, min:0, max:52 };
widthRange[66] = { sel:66, min:52, max:70 };
widthRange[90] = { sel:90, min:70, max:94 };
var i = 1;
for (var key in widthRange)
{
document.write("Key #" + i + " = " + key + "; min/max = " + widthRange[key].min + "/" + widthRange[key].max + "<br />");
i++;
}
</script>
</html>
Results in the browser (Firefox 3.6.2 on Windows XP):
Key #1 = 46; min/max = 0/52
Key #2 = 66; min/max = 52/70
Key #3 = 90; min/max = 70/94
The given solutions should be modified to check source.hasOwnProperty(property)
in the for..in
loops before assigning - otherwise, you end up copying the properties of the whole prototype chain, which is rarely desired...
When finding user table, in case if want the table owner name also, you can use the following:
select su.name + '.' + so.name
from sysobjects so,
sysusers su
where so.type = 'U' and
so.uid = su.uid
order by su.name,
so.name
Let's illustrate what's happening here:
Python 3.1.2 (r312:79147, Sep 27 2010, 09:45:41)
[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> class Foo:
... def __init__(self, x=[]):
... x.append(1)
...
>>> Foo.__init__.__defaults__
([],)
>>> f = Foo()
>>> Foo.__init__.__defaults__
([1],)
>>> f2 = Foo()
>>> Foo.__init__.__defaults__
([1, 1],)
You can see that the default arguments are stored in a tuple which is an attribute of the function in question. This actually has nothing to do with the class in question and goes for any function. In python 2, the attribute will be func.func_defaults
.
As other posters have pointed out, you probably want to use None
as a sentinel value and give each instance it's own list.
I just came up with a tricky way to get almost the same functionality. Instead of protecting the sheet the normal way, use an event handler to undo anything the user tries to do.
Add the following to the worksheet's module:
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Locked = True Then
Application.EnableEvents = False
Application.Undo
Application.EnableEvents = True
End If
End Sub
If the user does anything to change a cell that's locked, the action will get immediately undone. The temporary disabling of events is to keep the undoing itself from triggering this event, resulting in an infinite loop.
Sorting and filtering do not trigger the Change event, so those functions remain enabled.
Note that this solution prevents changing or clearing cell contents, but does not prevent changing formats. A determined user could get around it by simply setting the cells to be unlocked.
My favorite way is called do the sleep to 50. here i
variable need to be used inside echo statements.
for i in $(seq 1 50); do
echo -ne "$i%\033[0K\r"
sleep 50
done
echo "ended"

I have a project that uses generators a lot and needed this to be automatic, so I copied the index_name
function from the rails source to override it. I added this in config/initializers/generated_index_name.rb
:
# make indexes shorter for postgres
require "active_record/connection_adapters/abstract/schema_statements"
module ActiveRecord
module ConnectionAdapters # :nodoc:
module SchemaStatements
def index_name(table_name, options) #:nodoc:
if Hash === options
if options[:column]
"ix_#{table_name}_on_#{Array(options[:column]) * '__'}".slice(0,63)
elsif options[:name]
options[:name]
else
raise ArgumentError, "You must specify the index name"
end
else
index_name(table_name, index_name_options(options))
end
end
end
end
end
It creates indexes like ix_assignments_on_case_id__project_id
and just truncates it to 63 characters if it's still too long. That's still going to be non-unique if the table name is very long, but you can add complications like shortening the table name separately from the column names or actually checking for uniqueness.
Note, this is from a Rails 5.2 project; if you decide to do this, copy the source from your version.
<input type="text" id="inputName" placeholder="Enter name" required oninvalid="this.setCustomValidity('Your Message')" oninput="this.setCustomValidity('') />

As offer_date
is an number, and is of lower accuracy than your real dates, this may work...
- Convert your real date to a string of format YYYYMM
- Conver that value to an INT
- Compare the result you your offer_date
SELECT
*
FROM
offers
WHERE
offer_date = (SELECT CAST(to_char(create_date, 'YYYYMM') AS INT) FROM customers where id = '12345678')
AND offer_rate > 0
Also, by doing all the manipulation on the create_date
you only do the processing on one value.
Additionally, had you manipulated the offer_date
you would not be able to utilise any index on that field, and so force SCANs instead of SEEKs.
The following module allows you to group Django models and still work with a QuerySet in the result: https://github.com/kako-nawao/django-group-by
For example:
from django_group_by import GroupByMixin
class BookQuerySet(QuerySet, GroupByMixin):
pass
class Book(Model):
title = TextField(...)
author = ForeignKey(User, ...)
shop = ForeignKey(Shop, ...)
price = DecimalField(...)
class GroupedBookListView(PaginationMixin, ListView):
template_name = 'book/books.html'
model = Book
paginate_by = 100
def get_queryset(self):
return Book.objects.group_by('title', 'author').annotate(
shop_count=Count('shop'), price_avg=Avg('price')).order_by(
'name', 'author').distinct()
def get_context_data(self, **kwargs):
return super().get_context_data(total_count=self.get_queryset().count(), **kwargs)
'book/books.html'
<ul>
{% for book in object_list %}
<li>
<h2>{{ book.title }}</td>
<p>{{ book.author.last_name }}, {{ book.author.first_name }}</p>
<p>{{ book.shop_count }}</p>
<p>{{ book.price_avg }}</p>
</li>
{% endfor %}
</ul>
The difference to the annotate
/aggregate
basic Django queries is the use of the attributes of a related field, e.g. book.author.last_name
.
If you need the PKs of the instances that have been grouped together, add the following annotation:
.annotate(pks=ArrayAgg('id'))
NOTE: ArrayAgg
is a Postgres specific function, available from Django 1.9 onwards: https://docs.djangoproject.com/en/1.10/ref/contrib/postgres/aggregates/#arrayagg
A good combination of String extensions:
public static byte[] GetBytes(this string str)
{
byte[] bytes = new byte[str.Length * sizeof(char)];
System.Buffer.BlockCopy(str.ToCharArray(), 0, bytes, 0, bytes.Length);
return bytes;
}
public static Stream ToStream(this string str)
{
Stream StringStream = new MemoryStream();
StringStream.Read(str.GetBytes(), 0, str.Length);
return StringStream;
}
If you used any plugin for seo then Check 1st your seo plugin settings.Then find out Noindex setting if Enable Media for Noindex then disable it.
You first need to add values to your select
options and for easy targetting give the select
itself an id
.
Let's make option b
the default:
<select id="mySelect">
<option>a</option>
<option selected="selected">b</option>
<option>c</option>
</select>
Now you can change the default selected value with JavaScript like this:
<script>
var temp = "a";
var mySelect = document.getElementById('mySelect');
for(var i, j = 0; i = mySelect.options[j]; j++) {
if(i.value == temp) {
mySelect.selectedIndex = j;
break;
}
}
</script>

The Python 3 range()
object doesn't produce numbers immediately; it is a smart sequence object that produces numbers on demand. All it contains is your start, stop and step values, then as you iterate over the object the next integer is calculated each iteration.
The object also implements the object.__contains__
hook, and calculates if your number is part of its range. Calculating is a (near) constant time operation *. There is never a need to scan through all possible integers in the range.
From the range()
object documentation:
The advantage of the
range
type over a regularlist
ortuple
is that a range object will always take the same (small) amount of memory, no matter the size of the range it represents (as it only stores thestart
,stop
andstep
values, calculating individual items and subranges as needed).
So at a minimum, your range()
object would do:
class my_range:
def __init__(self, start, stop=None, step=1, /):
if stop is None:
start, stop = 0, start
self.start, self.stop, self.step = start, stop, step
if step < 0:
lo, hi, step = stop, start, -step
else:
lo, hi = start, stop
self.length = 0 if lo > hi else ((hi - lo - 1) // step) + 1
def __iter__(self):
current = self.start
if self.step < 0:
while current > self.stop:
yield current
current += self.step
else:
while current < self.stop:
yield current
current += self.step
def __len__(self):
return self.length
def __getitem__(self, i):
if i < 0:
i += self.length
if 0 <= i < self.length:
return self.start + i * self.step
raise IndexError('my_range object index out of range')
def __contains__(self, num):
if self.step < 0:
if not (self.stop < num <= self.start):
return False
else:
if not (self.start <= num < self.stop):
return False
return (num - self.start) % self.step == 0
This is still missing several things that a real range()
supports (such as the .index()
or .count()
methods, hashing, equality testing, or slicing), but should give you an idea.
I also simplified the __contains__
implementation to only focus on integer tests; if you give a real range()
object a non-integer value (including subclasses of int
), a slow scan is initiated to see if there is a match, just as if you use a containment test against a list of all the contained values. This was done to continue to support other numeric types that just happen to support equality testing with integers but are not expected to support integer arithmetic as well. See the original Python issue that implemented the containment test.
* Near constant time because Python integers are unbounded and so math operations also grow in time as N grows, making this a O(log N) operation. Since it’s all executed in optimised C code and Python stores integer values in 30-bit chunks, you’d run out of memory before you saw any performance impact due to the size of the integers involved here.
expr(1)

expr substr <string> <start-index> <length>

You can do what you are wanting but it isn't quite as nice as Notepad++ but it may work for small solutions decently enough.
In sublime if you hold ctrl, or mac equiv., and select the word/characters you want on a single line with the mouse and still holding ctrl go to another line and select the word/characters you want on that line it will be additive and you will build your selection. I mainly use notepadd++ as my extractor and data cleanup and sublime for actual development.
The other way is if your columns are in perfect alignment you can simply middle click on windows or option + click on mac and this enables you to select text in a square like fashion, Columns, inside the lines of text.
You want to pass the function object hi
to your loop()
function, not the result of a call to hi()
(which is None
since hi()
doesn't return anything).
So try this:
>>> loop(hi, 5)
hi
hi
hi
hi
hi
Perhaps this will help you understand better:
>>> print hi()
hi
None
>>> print hi
<function hi at 0x0000000002422648>

Use MS Access. I have a file of 2,673,404 records. It will not open in notepad++ and excel will not load more than 1,048,576 records. It is tab delimited since I exported the data from a mysql database and I need it in csv format. So I imported it into Access. Change the file extension to .txt so MS Access will take you through the import wizard.
MS Access will link to your file so for the database to stay intact keep the csv file

I spent most of last week at a university library studying debugging of concurrent code. The central problem is concurrent code is non-deterministic. Typically, academic debugging has fallen into one of three camps here:
Now, as above commentators have noticed, you can design your concurrent system into a more deterministic state. However, if you don't do that properly, you're just back to designing a sequential system again.
My suggestion would be to focus on having a very strict design protocol about what gets threaded and what doesn't get threaded. If you constrain your interface so that there is minimal dependancies between elements, it is much easier.
Good luck, and keep working on the problem.

You can't create arrays with a generic component type.
Create an array of an explicit type, like Object[]
, instead. You can then cast this to PCB[]
if you want, but I don't recommend it in most cases.
PCB[] res = (PCB[]) new Object[list.size()]; /* Not type-safe. */
If you want type safety, use a collection like java.util.List<PCB>
instead of an array.
By the way, if list
is already a java.util.List
, you should use one of its toArray()
methods, instead of duplicating them in your code. This doesn't get your around the type-safety problem though.

two things one is that a /D after the CD may prove to be useful in making sure the directory is changed but it's not really necessary, second, if you are going to pass this from user to user you have to add, instead of your name, the code %username%, this makes the code usable on any computer, as long as they have your setup.exe file in the same location as you do on your computer. of course making sure of that is more difficult. also...
start \\filer\repo\lab\"software"\"myapp"\setup.exe
the start code here, can be set up like that, but the correct syntax is
start "\\filter\repo\lab\software\myapp\" setup.exe
This will run: setup.exe, located in: \filter\repo\lab...etc.\
For MVC5, in case you are building an application from scratch. You need to add a web.config file to the Views folder and paste the following code in it.
<?xml version="1.0"?>
<configuration>
<configSections>
<sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">

Pure Windows cmd/bat solution:
svn cleanup .
svn revert -R .
For /f "tokens=1,2" %%A in ('svn status --no-ignore') Do (
If [%%A]==[?] ( Call :UniDelete %%B
) Else If [%%A]==[I] Call :UniDelete %%B
)
svn update .
goto :eof
:UniDelete delete file/dir
IF EXIST "%1\*" (
RD /S /Q "%1"
) Else (
If EXIST "%1" DEL /S /F /Q "%1"
)
goto :eof
I also had the same problem, but gladelly I fixed this by changing the type like from type="submit"
to type="button"
and it worked.
Instantiate a new ArrayList:
List<String> myList = new ArrayList<String>();
Iterate over your data structure (with a for loop, for instance, more details on your code would help.) and for each element (yourElement):
myList.add(yourElement);
Consider having multiple matlab sessions. Keep the main session window (the pretty one with all the colours, file manager, command history, workspace, editor etc.) for running stuff that you know will terminate.
Stuff that you are experimenting with, say you are messing with ode suite and you get lots of warnings: matrix singular, because you altered some parameter and didn't predict what would happen, run in a separate session:
dos('matlab -automation -r &')
You can kill that without having to restart the whole of Matlab.
Edit the configuration and then in the box: Script path, select your .py file!
The shortest solution for the year 2020 (for those happy people who don't need to support IE)
Tested in Chrome, Firefox, Safari.
function onBeforeUnload(e) {
if (thereAreUnsavedChanges()) {
e.preventDefault();
e.returnValue = '';
return;
}
delete e['returnValue'];
}
window.addEventListener('beforeunload', onBeforeUnload);
Actually no one modern browser (Chrome, Firefox, Safari) displays the "return value" as a question to user. Instead they show their own confirmation text (it depends on browser). But we still need to return some (even empty) string to trigger that confirmation on Chrome.
Just to add my results, also using Matplotlib.
.eps made all my text bold and removed transparency. .svg gave me high-resolution pictures that actually looked like my graph.
import matplotlib.pyplot as plt
fig, ax = plt.subplots()
# Do the plot code
fig.savefig('myimage.svg', format='svg', dpi=1200)
I used 1200 dpi because a lot of scientific journals require images in 1200 / 600 / 300 dpi, depending on what the image is of. Convert to desired dpi and format in GIMP or Inkscape.
Obviously the dpi doesn't matter since .svg are vector graphics and have "infinite resolution".
As mentioned in comments, this is a scoping issue. Specifically, $con
is not in scope within your getPosts
function.
You should pass your connection object in as a dependency, eg
function getPosts(mysqli $con) {
// etc
I would also highly recommend halting execution if your connection fails or if errors occur. Something like this should suffice
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT); // throw exceptions
$con=mysqli_connect("localhost","xxxx","xxxx","xxxxx");
getPosts($con);
The blocksize is usually selected to maximize the "occupancy". Search on CUDA Occupancy for more information. In particular, see the CUDA Occupancy Calculator spreadsheet.
typeof document.location; // 'object'
typeof document.location.href; // 'string'
The href
property is a string, while document.location
itself is an object.
This Method to get Google Username:
public String getUsername() {
AccountManager manager = AccountManager.get(this);
Account[] accounts = manager.getAccountsByType("com.google");
List<String> possibleEmails = new LinkedList<String>();
for (Account account : accounts) {
// TODO: Check possibleEmail against an email regex or treat
// account.name as an email address only for certain account.type
// values.
possibleEmails.add(account.name);
}
if (!possibleEmails.isEmpty() && possibleEmails.get(0) != null) {
String email = possibleEmails.get(0);
String[] parts = email.split("@");
if (parts.length > 0 && parts[0] != null)
return parts[0];
else
return null;
} else
return null;
}
simple this method call ....
And Get Google User in Gmail id::
accounts = AccountManager.get(this).getAccounts();
Log.e("", "Size: " + accounts.length);
for (Account account : accounts) {
String possibleEmail = account.name;
String type = account.type;
if (type.equals("com.google")) {
strGmail = possibleEmail;
Log.e("", "Emails: " + strGmail);
break;
}
}
After add permission in manifest;
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
You should probably re-write the script to return a value rather than output it. Instead of:
a=$( script.sh ) # Now a is a string, either "success" or "Failed"
case "$a" in
success) echo script succeeded;;
Failed) echo script failed;;
esac
you would be able to do:
if script.sh > /dev/null; then
echo script succeeded
else
echo script failed
fi
It is much simpler for other programs to work with you script if they do not have to parse the output. This is a simple change to make. Just exit 0
instead of printing success
, and exit 1
instead of printing Failed
. Of course, you can also print those values as well as exiting with a reasonable return value, so that wrapper scripts have flexibility in how they work with the script.
I've implemented it like this:
Public Function LastRowWithData(ByVal strCol As String, ByVal intRow As Integer) As Long
Range(strCol & intRow).Select
LastRowWithData= ActiveSheet.Cells(ActiveSheet.Rows.Count, strCol).End(xlUp).Row
End Function
You can make it even simplier, if you want to avoid extra structures.
service:
mappings:
key1: value1
key2: value2
@Configuration
@EnableConfigurationProperties
public class ServiceConfigurationProperties {
@Bean
@ConfigurationProperties(prefix = "service.mappings")
public Map<String, String> serviceMappings() {
return new HashMap<>();
}
}
And then use it as usual, for example with a constructor:
public class Foo {
private final Map<String, String> serviceMappings;
public Foo(Map<String, String> serviceMappings) {
this.serviceMappings = serviceMappings;
}
}

You can use unirest, It provides easy method to post request. `
import unirest
def callback(response):
print "code:"+ str(response.code)
print "******************"
print "headers:"+ str(response.headers)
print "******************"
print "body:"+ str(response.body)
print "******************"
print "raw_body:"+ str(response.raw_body)
# consume async post request
def consumePOSTRequestASync():
params = {'test1':'param1','test2':'param2'}
# we need to pass a dummy variable which is open method
# actually unirest does not provide variable to shift between
# application-x-www-form-urlencoded and
# multipart/form-data
params['dummy'] = open('dummy.txt', 'r')
url = 'http://httpbin.org/post'
headers = {"Accept": "application/json"}
# call get service with headers and params
unirest.post(url, headers = headers,params = params, callback = callback)
# post async request multipart/form-data

Take a look at "using WCF Services with PHP". It explains the basics of what you need.
As a theory summary:
WCF or Windows Communication Foundation is a technology that allow to define services abstracted from the way - the underlying communication method - they'll be invoked.
The idea is that you define a contract about what the service does and what the service offers and also define another contract about which communication method is used to actually consume the service, be it TCP, HTTP or SOAP.
You have the first part of the article here, explaining how to create a very basic WCF Service.
More resources:
Aslo take a look to NuSOAP. If you now NuSphere this is a toolkit to let you connect from PHP to an WCF service.
In kotlin: Object class implements Serializable:
class MyClass: Serializable {
//members
}
At the point where the object sending:
val fragment = UserDetailFragment()
val bundle = Bundle()
bundle.putSerializable("key", myObject)
fragment.arguments = bundle
At the fragment, where we want to get our object:
val bundle: Bundle? = arguments
bundle?.let {
val myObject = it.getSerializable("key") as MyClass
myObject.memberName?.let { it1 -> showShortToast(it1) }
}
The statement from Microsoft regarding the end of Internet Explorer 11 support mentions that it will continue to receive security updates, compatibility fixes, and technical support until its end of life. The wording of this statement leads me to believe that Microsoft has no plans to continue adding features to Internet Explorer 11, and instead will be focusing on Edge.
If you require ES6 features in Internet Explorer 11, check out a transpiler such as Babel.
You can use recyclerView.getChildAt()
to get each visible child, and setting some tag convertview.setTag(index)
on these view in adapter code will help you to relate it with adapter data.
what you need is:
[\-\+]?[0-9]*(\.[0-9]+)?
I escaped the "+" and "-" sign and also grouped the decimal with its following digits since something like "1." is not a valid number.
The changes will allow you to match integers and floats. for example:
0
+1
-2.0
2.23442
All your elements should have a unique IDs, so there should not be more than one element with #myid
An "id" is a unique identifier. Each time this attribute is used in a document it must have a different value. If you are using this attribute as a hook for style sheets it may be more appropriate to use classes (which group elements) than id (which are used to identify exactly one element).
Neverthless, try this:
$("span[id=myid]").remove();
To tint an image, you can use CSS3 background
to stack images and a linear-gradient
. In the example below, I use a linear-gradient
with no actual gradient. The browser treats gradients as images (I think it actually generates a bitmap and overlays it) and thus, is actually stacking multiple images.
background: linear-gradient(0deg, rgba(2,173,231,0.5), rgba(2,173,231,0.5)), url(images/mba-grid-5px-bg.png) repeat;
Will yield a graph-paper with light blue tint, if you had the png. Note that the stacking order might work in reverse to your mental model, with the first item being on top.
Excellent documentation by Mozilla, here:
https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Using_multiple_backgrounds
Tool for building the gradients:

In Java 8:
LinkedHashMap<Integer, String> sortedMap =
map.entrySet().stream().
sorted(Entry.comparingByValue()).
collect(Collectors.toMap(Entry::getKey, Entry::getValue,
(e1, e2) -> e1, LinkedHashMap::new));
There are 2 ways:
ScrollView.setScrollbarFadingEnabled(false);
android:fadeScrollbars="false"
Simple as that!
I saw this thread when I was trying to split a file in files with 100 000 lines. A better solution than sed for that is:
split -l 100000 database.sql database-
It will give files like:
database-aaa
database-aab
database-aac
...
Everywhere inside the query string, the wildcard should be ?
instead of '?'
. That should solve the problem.
EDIT :
To add to that, you need to change date '?'
to to_date(?, 'yyyy-mm-dd')
. Please try that and let me know.
The default key binding for this is Ctrl+Shift+Space.
The underlying Visual Studio command is Edit.ParameterInfo
.
If the standard keybinding doesn't work for you (possible in some profiles) then you can change it via the keyboard options page
I was heard that, one of the reasons is , the project is too large, so increasing the post buffer could solve the problem. so open the editSystemWideGitConfig, and add the following statements under [http] , postBuffer = 524288000. maybe work.
From the API 21 on it's very easy to change the color of the stars with this three lines of code:
android:progressTint="@android:color/holo_red_dark"
android:progressBackgroundTint="@android:color/holo_red_dark"
android:secondaryProgressTint="@android:color/holo_red_dark"
Doing it like this, you'll change:
Assuming you want to change the url to another within the same domain, you can use this:
history.pushState('data', '', 'http://www.yourcurrentdomain.com/new/path');
You can use Strings replace method with a regular expression.
"Hello World ".replace(/ /g, "");
The replace() method returns a new string with some or all matches of a pattern replaced by a replacement. The pattern can be a string or a RegExp
/ / - Regular expression matching spaces
g - Global flag; find all matches rather than stopping after the first match
const str = "H e l l o World! ".replace(/ /g, "");_x000D_
document.getElementById("greeting").innerText = str;
_x000D_
<p id="greeting"><p>
_x000D_
This is just an informational message. Your issue might be a missmatch between the versions of chromedriver and selenium-server-standalone.
Try with the latest selenium version 3.0, it is working for me.
Please not that for selenium 3.0 you need to specify the driver first and after the selenium server.
With the new selenium, which is 3.0 you should use:
java -Dwebdriver.chrome.driver=path_to_chrome_driver -jar selenium-server-standalone-3.0.0-beta2.jar If you are using selenium version below 3.0 you need to reverse the order of selenium with the driver, like:
java -Dwebdriver.chrome.driver=path_to_chrome_driver -jar selenium_server.jar
When you are starting the selenium server, open a console in the directory with chromedriver and selenium server and execute the above command.
Corresponding to INSERT (Transact-SQL) (SQL Server 2005) you can't omit INSERT INTO dbo.Blah
and have to specify it every time or use another syntax/approach,
If there is no such mechanism, what is a pattern/convention for such problems?
The term 'cleanup' might be more appropriate, but will use 'destructor' to match OP
Suppose you write some javascript entirely with 'function's and 'var's.
Then you can use the pattern of writing all the function
s code within the framework of a try
/catch
/finally
lattice. Within finally
perform the destruction code.
Instead of the C++ style of writing object classes with unspecified lifetimes, and then specifying the lifetime by arbitrary scopes and the implicit call to ~()
at scope end (~()
is destructor in C++), in this javascript pattern the object is the function, the scope is exactly the function scope, and the destructor is the finally
block.
If you are now thinking this pattern is inherently flawed because try
/catch
/finally
doesn't encompass asynchronous execution which is essential to javascript, then you are correct. Fortunately, since 2018 the asynchronous programming helper object Promise
has had a prototype function finally
added to the already existing resolve
and catch
prototype functions. That means that that asynchronous scopes requiring destructors can be written with a Promise
object, using finally
as the destructor. Furthermore you can use try
/catch
/finally
in an async function
calling Promise
s with or without await
, but must be aware that Promise
s called without await will be execute asynchronously outside the scope and so handle the desctructor code in a final then
.
In the following code PromiseA
and PromiseB
are some legacy API level promises which don't have finally
function arguments specified. PromiseC
DOES have a finally argument defined.
async function afunc(a,b){
try {
function resolveB(r){ ... }
function catchB(e){ ... }
function cleanupB(){ ... }
function resolveC(r){ ... }
function catchC(e){ ... }
function cleanupC(){ ... }
...
// PromiseA preced by await sp will finish before finally block.
// If no rush then safe to handle PromiseA cleanup in finally block
var x = await PromiseA(a);
// PromiseB,PromiseC not preceded by await - will execute asynchronously
// so might finish after finally block so we must provide
// explicit cleanup (if necessary)
PromiseB(b).then(resolveB,catchB).then(cleanupB,cleanupB);
PromiseC(c).then(resolveC,catchC,cleanupC);
}
catch(e) { ... }
finally { /* scope destructor/cleanup code here */ }
}
I am not advocating that every object in javascript be written as a function. Instead, consider the case where you have a scope identified which really 'wants' a destructor to be called at its end of life. Formulate that scope as a function object, using the pattern's finally
block (or finally
function in the case of an asynchronous scope) as the destructor. It is quite like likely that formulating that functional object obviated the need for a non-function class which would otherwise have been written - no extra code was required, aligning scope and class might even be cleaner.
Note: As others have written, we should not confuse destructors and garbage collection. As it happens C++ destructors are often or mainly concerned with manual garbage collection, but not exclusively so. Javascript has no need for manual garbage collection, but asynchronous scope end-of-life is often a place for (de)registering event listeners, etc..
If you have the suhosin extension enabled, it can prevent scripts from setting the memory limit beyond what it started with or some defined cap.
http://www.hardened-php.net/suhosin/configuration.html#suhosin.memory_limit
static means it belongs to the class not an instance, this means that there is only one copy of that variable/method shared between all instances of a particular Class.
public class MyClass {
public static int myVariable = 0;
}
//Now in some other code creating two instances of MyClass
//and altering the variable will affect all instances
MyClass instance1 = new MyClass();
MyClass instance2 = new MyClass();
MyClass.myVariable = 5; //This change is reflected in both instances
final is entirely unrelated, it is a way of defining a once only initialization. You can either initialize when defining the variable or within the constructor, nowhere else.
note A note on final methods and final classes, this is a way of explicitly stating that the method or class can not be overridden / extended respectively.
Extra Reading So on the topic of static, we were talking about the other uses it may have, it is sometimes used in static blocks. When using static variables it is sometimes necessary to set these variables up before using the class, but unfortunately you do not get a constructor. This is where the static keyword comes in.
public class MyClass {
public static List<String> cars = new ArrayList<String>();
static {
cars.add("Ferrari");
cars.add("Scoda");
}
}
public class TestClass {
public static void main(String args[]) {
System.out.println(MyClass.cars.get(0)); //This will print Ferrari
}
}
You must not get this confused with instance initializer blocks which are called before the constructor per instance.
Just a quick chime in here to hopefully help others... Especially with the newer version (since this is 2 years old)...
Instead of having some static fields defined in JS, you can also use the data-rule-*
attributes. You can use built-in rules as well as custom rules.
See http://jqueryvalidation.org/documentation/#link-list-of-built-in-validation-methods for built-in rules.
Example:
<p><label>Email: <input type="text" name="email" id="email" data-rule-email="true" required></label></p>
<p><label>Confirm Email: <input type="text" name="email" id="email_confirm" data-rule-email="true" data-rule-equalTo="#email" required></label></p>
Note the data-rule-*
attributes.

This is the actual cause of the problem:
Caused by: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure
You have a database communication link problem. Make sure that your application have network access to your database (and the firewall isn't blocking ports to your database).
Update: This process is so common, that the git team made it much simpler with a new tool, git subtree
. See here: Detach (move) subdirectory into separate Git repository
You want to clone your repository and then use git filter-branch
to mark everything but the subdirectory you want in your new repo to be garbage-collected.
To clone your local repository:
git clone /XYZ /ABC
(Note: the repository will be cloned using hard-links, but that is not a problem since the hard-linked files will not be modified in themselves - new ones will be created.)
Now, let us preserve the interesting branches which we want to rewrite as well, and then remove the origin to avoid pushing there and to make sure that old commits will not be referenced by the origin:
cd /ABC
for i in branch1 br2 br3; do git branch -t $i origin/$i; done
git remote rm origin
or for all remote branches:
cd /ABC
for i in $(git branch -r | sed "s/.*origin\///"); do git branch -t $i origin/$i; done
git remote rm origin
Now you might want to also remove tags which have no relation with the subproject; you can also do that later, but you might need to prune your repo again. I did not do so and got a WARNING: Ref 'refs/tags/v0.1' is unchanged
for all tags (since they were all unrelated to the subproject); additionally, after removing such tags more space will be reclaimed. Apparently git filter-branch
should be able to rewrite other tags, but I could not verify this. If you want to remove all tags, use git tag -l | xargs git tag -d
.
Then use filter-branch and reset to exclude the other files, so they can be pruned. Let's also add --tag-name-filter cat --prune-empty
to remove empty commits and to rewrite tags (note that this will have to strip their signature):
git filter-branch --tag-name-filter cat --prune-empty --subdirectory-filter ABC -- --all
or alternatively, to only rewrite the HEAD branch and ignore tags and other branches:
git filter-branch --tag-name-filter cat --prune-empty --subdirectory-filter ABC HEAD
Then delete the backup reflogs so the space can be truly reclaimed (although now the operation is destructive)
git reset --hard
git for-each-ref --format="%(refname)" refs/original/ | xargs -n 1 git update-ref -d
git reflog expire --expire=now --all
git gc --aggressive --prune=now
and now you have a local git repository of the ABC sub-directory with all its history preserved.
Note: For most uses, git filter-branch
should indeed have the added parameter -- --all
. Yes that's really --space-- all
. This needs to be the last parameters for the command. As Matli discovered, this keeps the project branches and tags included in the new repo.
Edit: various suggestions from comments below were incorporated to make sure, for instance, that the repository is actually shrunk (which was not always the case before).
Update 2013 - This was written around Node v0.2 and v0.4; There are much better utilites now around logging. I highly recommend Winston
Update Late 2013 - We still use winston, but now with a logger library to wrap the functionality around logging of custom objects and formatting. Here is a sample of our logger.js https://gist.github.com/rtgibbons/7354879
Should be as simple as this.
var access = fs.createWriteStream(dir + '/node.access.log', { flags: 'a' })
, error = fs.createWriteStream(dir + '/node.error.log', { flags: 'a' });
// redirect stdout / stderr
proc.stdout.pipe(access);
proc.stderr.pipe(error);
When the user wishes to exit all open activities, they should press a button which loads the first Activity that runs when your app starts, in my case "LoginActivity".
Intent intent = new Intent(getApplicationContext(), LoginActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra("EXIT", true);
startActivity(intent);
The above code clears all the activities except for LoginActivity. LoginActivity is the first activity that is brought up when the user runs the program. Then put this code inside the LoginActivity's onCreate, to signal when it should self destruct when the 'Exit' message is passed.
if (getIntent().getBooleanExtra("EXIT", false)) {
finish();
}
The answer you get to this question from the Android platform is: "Don't make an exit button. Finish activities the user no longer wants, and the Activity manager will clean them up as it sees fit."
I had the same problem. Try recompiling using -fPIC
flag.
Unfortunately DEBUG
is overloaded heavily. For instance, it's recommended to always generate and save a pdb file for RELEASE builds. Which means one of the -Zx
flags, and -DEBUG
linker option. While _DEBUG
relates to special debug versions of runtime library such as calls to malloc
and free
. Then NDEBUG
will disable assertions.
If you have the files written under .gitignore, remove the files and run git pull again. That helped me out.
under my .git/hooks folder, some sample files were missing. like commit-msg,post-commit.sample,post-update.sample...adding these files resolved my change id missing issue.
Thx guys, I finally found the solution, a really basic one.. In my controller I have
$scope.mySplit = function(string, nb) {
var array = string.split(',');
return array[nb];
}
and in my view
{{mySplit(string,0)}}
ignorecase
to false
in git configAs the original post is about "Changing capitalization of filenames in Git":
If you are trying to change capitalisation of a filename in your project, you do not need to force rename it from Git. IMO, I would rather change the capitalisation from my IDE/editor and make sure that I configure Git properly to pick up the renaming.
By default, a Git template is set to ignore case (Git case insensitive). To verify you have the default template, use --get
to retrieve the value for a specified key. Use --local
and --global
to indicate to Git whether to pick up a configuration key-value from your local Git repository configuration or global one. As an example, if you want to lookup your global key core.ignorecase
:
git config --global --get core.ignorecase
If this returns true
, make sure to set it as:
git config --global core.ignorecase false
(Make sure you have proper permissions to change global.) And there you have it; now your Git installation would not ignore capitalisations and treat them as changes.
As a suggestion, if you are working on multi-language projects and you feel not all projects should be treated as case-sensitive by Git, just update the local core.ignorecase
file.
