I verified permissions but all was good (mongod:mongod). As I'm working on a large project and from a similar issue in our dev environment where we had a script consuming all available disk space, I could see in the error messages that mongod needs at least 3.7Gb free disk space to run..
I checked my own disk space only to see that less than 2Gb was remaining. After moving / erasing some data I can successfully start mongod again.
Hope this helps ;-)
I have mongo version 3.2.1 and had to delete the lock file from /data/db/
and after this, ran mongod
and it started successfully.
>rm /data/db/mongod.lock
>mongod
You should create a startup.bat
if you're using Windows, much more convenient:
C:\mongodb\mongodb-win32-x86_64-eiditon\bin\mongod.exe --dbpath C:\mongodb\data
And just dbclick startup.bat and mongodb will run using C:\mongodb\data
as its data folder.
There are two issues:
To get the coordinates you don't need the Internet. GPS is satellite-based. But to derive street/city information from the coordinates, you'd need either to implement the map and the corresponding algorithms yourself on the device (a lot of work!) or to rely on proven services, e.g. by Google, in which case you'd need an Internet connection.
As of recently, Google allows for caching the maps, which would at least allow you to show your current position on the map even without a data connection, provided, you had cached the map in advance, when you could access the Internet.
Use XMLHttpRequest
var xhr = new XMLHttpRequest();
xhr.open("POST", '/server', true);
//Send the proper header information along with the request
xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
xhr.onreadystatechange = function() { // Call a function when the state changes.
if (this.readyState === XMLHttpRequest.DONE && this.status === 200) {
// Request finished. Do processing here.
}
}
xhr.send("foo=bar&lorem=ipsum");
// xhr.send(new Int8Array());
// xhr.send(document);
You can use just:
"{0:b}".format(n)
In my opinion this is the easiest way!
Follow the below steps,
The solution for this is that remove this following dependency:
implementation 'com.android.support:design:26.1.0'
put general dependencies as:
dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
//noinspection GradleCompatible
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support:support-compat:26.1.0'

So here we go:
If You use LINQ with EF looking for some exact elements contained in the list like this:
await context.MyObject1.Include("MyObject2").Where(t => IdList.Contains(t.MyObjectId)).ToListAsync();
everything is going fine until IdList contains more than one Id.
The “timeout” problem comes out if the list contains just one Id. To resolve the issue use if condition to check number of ids in IdList.
Example:
if (IdList.Count == 1)
{
result = await entities. MyObject1.Include("MyObject2").Where(t => IdList.FirstOrDefault()==t. MyObjectId).ToListAsync();
}
else
{
result = await entities. MyObject1.Include("MyObject2").Where(t => IdList.Contains(t. MyObjectId)).ToListAsync();
}

I know this is old, but I ran into the same issue. I'm on a Mac/Ubuntu and switch back and forth. What I have found is that just sending a simple interrupt signal to the main R process does exactly what you're looking for. I've ran scripts that went on for as long as 24 hours and the signal interrupt works very well. You should be able to run kill in terminal:
$ kill -2 pid
You can find the pid by running
$ps aux | grep exec/R
Not sure about Windows since I'm not ever on there, but I can't imagine there's not an option to do this as well in Command Prompt/Task Manager
Hope this helps!
The Bootstrap team seems to have removed it. See here: https://github.com/twbs/bootstrap/issues/8922 . @Skelly's answer involves custom css which I didn't want to do so I used the grid system and nav-pills. It worked fine and looked great. The code looks like so:
<div class="row">
<!-- Navigation Buttons -->
<div class="col-md-3">
<ul class="nav nav-pills nav-stacked" id="myTabs">
<li class="active"><a href="#home" data-toggle="pill">Home</a></li>
<li><a href="#profile" data-toggle="pill">Profile</a></li>
<li><a href="#messages" data-toggle="pill">Messages</a></li>
</ul>
</div>
<!-- Content -->
<div class="col-md-9">
<div class="tab-content">
<div class="tab-pane active" id="home">Home</div>
<div class="tab-pane" id="profile">Profile</div>
<div class="tab-pane" id="messages">Messages</div>
</div>
</div>
</div>
You can see this in action here: http://bootply.com/81948
[Update]
@SeanK gives the option of not having to enable the nav-pills through Javascript and instead using data-toggle="pill"
. Check it out here: http://bootply.com/96067. Thanks Sean.
You could use PhantomJS, which is a headless webkit (the rendering engine in safari and (up until recently) chrome) driver. You can learn how to do screen capture of pages here. Hope that helps!
if you're not familiar with Fiddler - please do. It's a great debugging tool for HTTP. You also have the option to limit the bandwidth.
The issue may happen while fetching dependencies from a remote repository. In my case, the repository did not need any authentication and it has been resolved by removing the servers section in the settings.xml file:
<servers>
<server>
<id>SomeRepo</id>
<username>SomeUN</username>
<password>SomePW</password>
</server>
</servers>
ps: I guess your target is mvn clean install instead of maven install clean
The comparator should be only for the key, not for the whole entry. It sorts the entries based on the keys.
You should change it to something as follows
SortedMap<String, Double> myMap =
new TreeMap<String, Double>(new Comparator<String>()
{
public int compare(String o1, String o2)
{
return o1.compareTo(o2);
}
});
Update
You can do something as follows (create a list of entries in the map and sort the list base on value, but note this not going to sort the map itself) -
List<Map.Entry<String, Double>> entryList = new ArrayList<Map.Entry<String, Double>>(myMap.entrySet());
Collections.sort(entryList, new Comparator<Map.Entry<String, Double>>() {
@Override
public int compare(Entry<String, Double> o1, Entry<String, Double> o2) {
return o1.getValue().compareTo(o2.getValue());
}
});
Note: all of the other answers here will fail if the two vectors have either the same direction (ex, (1, 0, 0)
, (1, 0, 0)
) or opposite directions (ex, (-1, 0, 0)
, (1, 0, 0)
).
Here is a function which will correctly handle these cases:
import numpy as np
def unit_vector(vector):
""" Returns the unit vector of the vector. """
return vector / np.linalg.norm(vector)
def angle_between(v1, v2):
""" Returns the angle in radians between vectors 'v1' and 'v2'::
>>> angle_between((1, 0, 0), (0, 1, 0))
1.5707963267948966
>>> angle_between((1, 0, 0), (1, 0, 0))
0.0
>>> angle_between((1, 0, 0), (-1, 0, 0))
3.141592653589793
"""
v1_u = unit_vector(v1)
v2_u = unit_vector(v2)
return np.arccos(np.clip(np.dot(v1_u, v2_u), -1.0, 1.0))
So many answers to such a seemingly simple question. Just to shake things up a little bit here is my solution to this problem.
Creating a Mutex can be troublesome because the JIT-er only sees you using it for a small portion of your code and wants to mark it as ready for garbage collection. It pretty much wants to out-smart you thinking you are not going to be using that Mutex for that long. In reality you want to hang onto this Mutex for as long as your application is running. The best way to tell the garbage collector to leave you Mutex alone is to tell it to keep it alive though out the different generations of garage collection. Example:
var m = new Mutex(...);
...
GC.KeepAlive(m);
I lifted the idea from this page: http://www.ai.uga.edu/~mc/SingleInstance.html
There is no need to add any extra div wrapper as others suggest.
The simplest way is to wrap your input element inside a related label tag and set input style to display:block
.
Bonus point earned: now you don't need to set the labels for
attribute. Because every label target the nested input.
<form name="message" method="post">
<section>
<label class="left">
Name
<input id="name" type="text" name="name">
</label>
<label class="right">
Email
<input id="email" type="text" name="email">
</label>
</section>
</form>
Simply call test2
from test1
like:
EXEC test2 @newId, @prod, @desc;
Make sure to get @id
using SCOPE_IDENTITY(), which gets the last identity value inserted into an identity column in the same scope:
SELECT @newId = SCOPE_IDENTITY()
The binary in 'convert to binary' can refer to three main things. The positional number system, the binary representation in memory or 32bit bitstrings. (for 64bit bitstrings see Patrick Roberts' answer)
1. Number System
(123456).toString(2)
will convert numbers to the base 2 positional numeral system. In this system negative numbers are written with minus signs just like in decimal.
2. Internal Representation
The internal representation of numbers is 64 bit floating point and some limitations are discussed in this answer. There is no easy way to create a bit-string representation of this in javascript nor access specific bits.
3. Masks & Bitwise Operators
MDN has a good overview of how bitwise operators work. Importantly:
Bitwise operators treat their operands as a sequence of 32 bits (zeros and ones)
Before operations are applied the 64 bit floating points numbers are cast to 32 bit signed integers. After they are converted back.
Here is the MDN example code for converting numbers into 32-bit strings.
function createBinaryString (nMask) {
// nMask must be between -2147483648 and 2147483647
for (var nFlag = 0, nShifted = nMask, sMask = ""; nFlag < 32;
nFlag++, sMask += String(nShifted >>> 31), nShifted <<= 1);
return sMask;
}
createBinaryString(0) //-> "00000000000000000000000000000000"
createBinaryString(123) //-> "00000000000000000000000001111011"
createBinaryString(-1) //-> "11111111111111111111111111111111"
createBinaryString(-1123456) //-> "11111111111011101101101110000000"
createBinaryString(0x7fffffff) //-> "01111111111111111111111111111111"
Let's say I have code in the directory ~/local_dir/myNewApp
, and I want to put it under 'https://svn.host/existing_path/myNewApp' (while being able to ignore some binaries, vendor libraries, etc.).
svn mkdir https://svn.host/existing_path/myNewApp
cd ~/local_dir
svn co https://svn.host/existing_path/myNewApp
. If your folder has a different name locally than in the repository, you must specify it as an additional argument.svn st
will now show all your files as ?
, which means that they are not currently under revision controlsvn add

The solution I found that caused me the least headaches:
git checkout <b1>
git checkout -b dummy
git merge <b2>
git checkout <b1>
git checkout dummy <path to file>
After doing that the file in path to file
in b2
is what it would be after a full merge with b1
.
To view the months of the current year, and only the months, use this format - it only takes the months of that year. It can also be restricted so that a certain number of months is displayed.
<input class="form-control" id="txtDateMMyyyy" autocomplete="off" required readonly/>
<script>
('#txtDateMMyyyy').datetimepicker({
format: "mm/yyyy",
startView: "year",
minView: "year"
}).datetimepicker("setDate", new Date());
</script>
The previous answers are now deprecated, you need to use ContextCompat.getColor
to retrieve the color properly:
root.setBackgroundColor(ContextCompat.getColor(getActivity(), R.color.white));
Some loaders (linkers) provide switches for turning dynamic loading on and off. If GCC is running on such a system (Solaris - and possibly others), then you can use the relevant option.
If you know which libraries you want to link statically, you can simply specify the static library file in the link line - by full path.
if you don't want to use MultipartFile.transferTo(). You can write file like this
val dir = File(filePackagePath)
if (!dir.exists()) dir.mkdirs()
val file = File("$filePackagePath${multipartFile.originalFilename}").apply {
createNewFile()
}
FileOutputStream(file).use {
it.write(multipartFile.bytes)
}
I had a similar problem with 'org.codehaus.mojo'-'jaxws-maven-plugin': could not resolve dependencies. Fortunately, I was able to do a Project > Clean in Eclipse, which resolved the issue.
Although this isn't going to be a problem for the person who asked the question, because they ran the program that was to produce the core file in a script with the ulimit command, I'd like to document that the ulimit command is specific to the shell in which you run it (like environment variables). I spent way too much time running ulimit and sysctl and stuff in one shell, and the command that I wanted to dump core in the other shell, and wondering why the core file was not produced.
I will be adding it to my bashrc. The sysctl works for all processes once it is issued, but the ulimit only works for the shell in which it is issued (maybe also the descendents too) - but not for other shells that happen to be running.

Update 2018:
This is an old question. Instead of still using this old non standard serialization format I would recommend to modify the server code to return better format for date. Either an ISO string containing time zone information, or only the milliseconds. If you use only the milliseconds for transport it should be UTC
on server and client.
2018-07-31T11:56:48Z
- ISO string can be parsed using new Date("2018-07-31T11:56:48Z")
and obtained from a Date
object
using dateObject.toISOString()
1533038208000
- milliseconds since midnight January 1, 1970, UTC - can be parsed using new Date(1533038208000) and obtained from a Date
object
using dateObject.getTime()
Sometimes you actually want to return a DataTable
than a DataView
. So a DataView
was not good in my case and I guess few others would want that too. Here is what I used to do
myDataTable.select("myquery").CopyToDataTable()
This will filter myDataTable
which is a DataTable and return a new DataTable
Hope someone will find that is useful
It's much simpler to run the task on the thread pool, rather than trying to trick the scheduler to run it synchronously. That way you can be sure that it won't deadlock. Performance is affected because of the context switch.
Task<MyResult> DoSomethingAsync() { ... }
// Starts the asynchronous task on a thread-pool thread.
// Returns a proxy to the original task.
Task<MyResult> task = Task.Run(() => DoSomethingAsync());
// Will block until the task is completed...
MyResult result = task.Result;
You seem to just have begun using mysql.
Simple answer: for now use
mysql -u root -p password
Password is usually root by default. You may use other usernames if you have created other user using create user in mysql. For details use "help, help manage accounts, help create users" etc. If you dont want your password to be shown in open just press return key after "-p" and you will be prompted for password next. Hope this resolves the issue.

If you don't know wether you have enough next elements in your container or not, you need to check against the end of your container between each increment. Neither ++ nor std::advance will do it for you.
if( ++iter == collection.end())
... // stop
if( ++iter == collection.end())
... // stop
You may even roll your own bound-secure advance function.
If you are sure that you will not go past the end, then std::advance( iter, 2 ) is the best solution.
t = (1, 2, 3)

You can't solve it. Simply answer1.sum()==0
, and you can't perform a division by zero.
This happens because answer1
is the exponential of 2 very large, negative numbers, so that the result is rounded to zero.
nan
is returned in this case because of the division by zero.
Now to solve your problem you could:
scipy/numpy
function that does exactly what you want! Check out @Warren Weckesser answer.Here I explain how to do some math manipulation that helps on this problem. We have that for the numerator:
exp(-x)+exp(-y) = exp(log(exp(-x)+exp(-y)))
= exp(log(exp(-x)*[1+exp(-y+x)]))
= exp(log(exp(-x) + log(1+exp(-y+x)))
= exp(-x + log(1+exp(-y+x)))
where above x=3* 1089
and y=3* 1093
. Now, the argument of this exponential is
-x + log(1+exp(-y+x)) = -x + 6.1441934777474324e-06
For the denominator you could proceed similarly but obtain that log(1+exp(-z+k))
is already rounded to 0
, so that the argument of the exponential function at the denominator is simply rounded to -z=-3000
. You then have that your result is
exp(-x + log(1+exp(-y+x)))/exp(-z) = exp(-x+z+log(1+exp(-y+x))
= exp(-266.99999385580668)
which is already extremely close to the result that you would get if you were to keep only the 2 leading terms (i.e. the first number 1089
in the numerator and the first number 1000
at the denominator):
exp(3*(1089-1000))=exp(-267)
For the sake of it, let's see how close we are from the solution of Wolfram alpha (link):
Log[(exp[-3*1089]+exp[-3*1093])/([exp[-3*1000]+exp[-3*4443])] -> -266.999993855806522267194565420933791813296828742310997510523
The difference between this number and the exponent above is +1.7053025658242404e-13
, so the approximation we made at the denominator was fine.
The final result is
'exp(-266.99999385580668) = 1.1050349147204485e-116
From wolfram alpha is (link)
1.105034914720621496.. × 10^-116 # Wolfram alpha.
and again, it is safe to use numpy here too.
Quick answer:
A child scope normally prototypically inherits from its parent scope, but not always. One exception to this rule is a directive with scope: { ... }
-- this creates an "isolate" scope that does not prototypically inherit. This construct is often used when creating a "reusable component" directive.
As for the nuances, scope inheritance is normally straightfoward... until you need 2-way data binding (i.e., form elements, ng-model) in the child scope. Ng-repeat, ng-switch, and ng-include can trip you up if you try to bind to a primitive (e.g., number, string, boolean) in the parent scope from inside the child scope. It doesn't work the way most people expect it should work. The child scope gets its own property that hides/shadows the parent property of the same name. Your workarounds are
New AngularJS developers often do not realize that ng-repeat
, ng-switch
, ng-view
, ng-include
and ng-if
all create new child scopes, so the problem often shows up when these directives are involved. (See this example for a quick illustration of the problem.)
This issue with primitives can be easily avoided by following the "best practice" of always have a '.' in your ng-models – watch 3 minutes worth. Misko demonstrates the primitive binding issue with ng-switch
.
Having a '.' in your models will ensure that prototypal inheritance is in play. So, use
<input type="text" ng-model="someObj.prop1">
<!--rather than
<input type="text" ng-model="prop1">`
-->
Also placed on the AngularJS wiki: https://github.com/angular/angular.js/wiki/Understanding-Scopes
It is important to first have a solid understanding of prototypal inheritance, especially if you are coming from a server-side background and you are more familiar with class-ical inheritance. So let's review that first.
Suppose parentScope has properties aString, aNumber, anArray, anObject, and aFunction. If childScope prototypically inherits from parentScope, we have:
(Note that to save space, I show the anArray
object as a single blue object with its three values, rather than an single blue object with three separate gray literals.)
If we try to access a property defined on the parentScope from the child scope, JavaScript will first look in the child scope, not find the property, then look in the inherited scope, and find the property. (If it didn't find the property in the parentScope, it would continue up the prototype chain... all the way up to the root scope). So, these are all true:
childScope.aString === 'parent string'
childScope.anArray[1] === 20
childScope.anObject.property1 === 'parent prop1'
childScope.aFunction() === 'parent output'
Suppose we then do this:
childScope.aString = 'child string'
The prototype chain is not consulted, and a new aString property is added to the childScope. This new property hides/shadows the parentScope property with the same name. This will become very important when we discuss ng-repeat and ng-include below.
Suppose we then do this:
childScope.anArray[1] = '22'
childScope.anObject.property1 = 'child prop1'
The prototype chain is consulted because the objects (anArray and anObject) are not found in the childScope. The objects are found in the parentScope, and the property values are updated on the original objects. No new properties are added to the childScope; no new objects are created. (Note that in JavaScript arrays and functions are also objects.)
Suppose we then do this:
childScope.anArray = [100, 555]
childScope.anObject = { name: 'Mark', country: 'USA' }
The prototype chain is not consulted, and child scope gets two new object properties that hide/shadow the parentScope object properties with the same names.
Takeaways:
One last scenario:
delete childScope.anArray
childScope.anArray[1] === 22 // true
We deleted the childScope property first, then when we try to access the property again, the prototype chain is consulted.
The contenders:
scope: true
, directive with transclude: true
.scope: { ... }
. This creates an "isolate" scope instead.Note, by default, directives do not create new scope -- i.e., the default is scope: false
.
Suppose we have in our controller:
$scope.myPrimitive = 50;
$scope.myObject = {aNumber: 11};
And in our HTML:
<script type="text/ng-template" id="/tpl1.html">
<input ng-model="myPrimitive">
</script>
<div ng-include src="'/tpl1.html'"></div>
<script type="text/ng-template" id="/tpl2.html">
<input ng-model="myObject.aNumber">
</script>
<div ng-include src="'/tpl2.html'"></div>
Each ng-include generates a new child scope, which prototypically inherits from the parent scope.
Typing (say, "77") into the first input textbox causes the child scope to get a new myPrimitive
scope property that hides/shadows the parent scope property of the same name. This is probably not what you want/expect.
Typing (say, "99") into the second input textbox does not result in a new child property. Because tpl2.html binds the model to an object property, prototypal inheritance kicks in when the ngModel looks for object myObject -- it finds it in the parent scope.
We can rewrite the first template to use $parent, if we don't want to change our model from a primitive to an object:
<input ng-model="$parent.myPrimitive">
Typing (say, "22") into this input textbox does not result in a new child property. The model is now bound to a property of the parent scope (because $parent is a child scope property that references the parent scope).
For all scopes (prototypal or not), Angular always tracks a parent-child relationship (i.e., a hierarchy), via scope properties $parent, $$childHead and $$childTail. I normally don't show these scope properties in the diagrams.
For scenarios where form elements are not involved, another solution is to define a function on the parent scope to modify the primitive. Then ensure the child always calls this function, which will be available to the child scope due to prototypal inheritance. E.g.,
// in the parent scope
$scope.setMyPrimitive = function(value) {
$scope.myPrimitive = value;
}
Here is a sample fiddle that uses this "parent function" approach. (The fiddle was written as part of this answer: https://stackoverflow.com/a/14104318/215945.)
See also https://stackoverflow.com/a/13782671/215945 and https://github.com/angular/angular.js/issues/1267.
ng-switch scope inheritance works just like ng-include. So if you need 2-way data binding to a primitive in the parent scope, use $parent, or change the model to be an object and then bind to a property of that object. This will avoid child scope hiding/shadowing of parent scope properties.
See also AngularJS, bind scope of a switch-case?
Ng-repeat works a little differently. Suppose we have in our controller:
$scope.myArrayOfPrimitives = [ 11, 22 ];
$scope.myArrayOfObjects = [{num: 101}, {num: 202}]
And in our HTML:
<ul><li ng-repeat="num in myArrayOfPrimitives">
<input ng-model="num">
</li>
<ul>
<ul><li ng-repeat="obj in myArrayOfObjects">
<input ng-model="obj.num">
</li>
<ul>
For each item/iteration, ng-repeat creates a new scope, which prototypically inherits from the parent scope, but it also assigns the item's value to a new property on the new child scope. (The name of the new property is the loop variable's name.) Here's what the Angular source code for ng-repeat actually is:
childScope = scope.$new(); // child scope prototypically inherits from parent scope
...
childScope[valueIdent] = value; // creates a new childScope property
If item is a primitive (as in myArrayOfPrimitives), essentially a copy of the value is assigned to the new child scope property. Changing the child scope property's value (i.e., using ng-model, hence child scope num
) does not change the array the parent scope references. So in the first ng-repeat above, each child scope gets a num
property that is independent of the myArrayOfPrimitives array:
This ng-repeat will not work (like you want/expect it to). Typing into the textboxes changes the values in the gray boxes, which are only visible in the child scopes. What we want is for the inputs to affect the myArrayOfPrimitives array, not a child scope primitive property. To accomplish this, we need to change the model to be an array of objects.
So, if item is an object, a reference to the original object (not a copy) is assigned to the new child scope property. Changing the child scope property's value (i.e., using ng-model, hence obj.num
) does change the object the parent scope references. So in the second ng-repeat above, we have:
(I colored one line gray just so that it is clear where it is going.)
This works as expected. Typing into the textboxes changes the values in the gray boxes, which are visible to both the child and parent scopes.
See also Difficulty with ng-model, ng-repeat, and inputs and https://stackoverflow.com/a/13782671/215945
Nesting controllers using ng-controller results in normal prototypal inheritance, just like ng-include and ng-switch, so the same techniques apply. However, "it is considered bad form for two controllers to share information via $scope inheritance" -- http://onehungrymind.com/angularjs-sticky-notes-pt-1-architecture/ A service should be used to share data between controllers instead.
(If you really want to share data via controllers scope inheritance, there is nothing you need to do. The child scope will have access to all of the parent scope properties. See also Controller load order differs when loading or navigating)
scope: false
) - the directive does not create a new scope, so there is no inheritance here. This is easy, but also dangerous because, e.g., a directive might think it is creating a new property on the scope, when in fact it is clobbering an existing property. This is not a good choice for writing directives that are intended as reusable components.scope: true
- the directive creates a new child scope that prototypically inherits from the parent scope. If more than one directive (on the same DOM element) requests a new scope, only one new child scope is created. Since we have "normal" prototypal inheritance, this is like ng-include and ng-switch, so be wary of 2-way data binding to parent scope primitives, and child scope hiding/shadowing of parent scope properties.scope: { ... }
- the directive creates a new isolate/isolated scope. It does not prototypically inherit. This is usually your best choice when creating reusable components, since the directive cannot accidentally read or modify the parent scope. However, such directives often need access to a few parent scope properties. The object hash is used to set up two-way binding (using '=') or one-way binding (using '@') between the parent scope and the isolate scope. There is also '&' to bind to parent scope expressions. So, these all create local scope properties that are derived from the parent scope.
Note that attributes are used to help set up the binding -- you can't just reference parent scope property names in the object hash, you have to use an attribute. E.g., this won't work if you want to bind to parent property parentProp
in the isolated scope: <div my-directive>
and scope: { localProp: '@parentProp' }
. An attribute must be used to specify each parent property that the directive wants to bind to: <div my-directive the-Parent-Prop=parentProp>
and scope: { localProp: '@theParentProp' }
.
__proto__
references Object.
Isolate scope's $parent references the parent scope, so although it is isolated and doesn't inherit prototypically from the parent scope, it is still a child scope.
<my-directive interpolated="{{parentProp1}}" twowayBinding="parentProp2">
and
scope: { interpolatedProp: '@interpolated', twowayBindingProp: '=twowayBinding' }
scope.someIsolateProp = "I'm isolated"
transclude: true
- the directive creates a new "transcluded" child scope, which prototypically inherits from the parent scope. The transcluded and the isolated scope (if any) are siblings -- the $parent property of each scope references the same parent scope. When a transcluded and an isolate scope both exist, isolate scope property $$nextSibling will reference the transcluded scope. I'm not aware of any nuances with the transcluded scope.
transclude: true
This fiddle has a showScope()
function that can be used to examine an isolate and transcluded scope. See the instructions in the comments in the fiddle.
There are four types of scopes:
scope: true
scope: {...}
. This one is not prototypal, but '=', '@', and '&' provide a mechanism to access parent scope properties, via attributes.transclude: true
. This one is also normal prototypal scope inheritance, but it is also a sibling of any isolate scope.For all scopes (prototypal or not), Angular always tracks a parent-child relationship (i.e., a hierarchy), via properties $parent and $$childHead and $$childTail.

I got this error while connecting to Amazon RDS. I checked the server status 50% of CPU usage while it was a development server and no one is using it.
It was working before, and nothing in the connection configuration has changed. Rebooting the server fixed the issue for me.
Like you I also faced many problems implementing OCR in Android, but after much Googling I found the solution, and it surely is the best example of OCR.
Let me explain using step-by-step guidance.
First, download the source code from https://github.com/rmtheis/tess-two.
Import all three projects. After importing you will get an error.
To solve the error you have to create a res
folder in the tess-two project
First, just create res folder in tess-two by tess-two->RightClick->new Folder->Name it "res"
After doing this in all three project the error should be gone.
Now download the source code from https://github.com/rmtheis/android-ocr, here you will get best example.
Now you just need to import it into your workspace, but first you have to download android-ndk from this site:
http://developer.android.com/tools/sdk/ndk/index.html i have windows 7 - 32 bit PC so I have download http://dl.google.com/android/ndk/android-ndk-r9-windows-x86.zip this file
Now extract it suppose I have extract it into E:\Software\android-ndk-r9 so I will set this path on Environment Variable
Right Click on MyComputer->Property->Advance-System-Settings->Advance->Environment Variable-> find PATH on second below Box and set like path like below picture
done it
Now open cmd and go to on D:\Android Workspace\tess-two like below
If you have successfully set up environment variable of NDK then just type ndk-build just like above picture than enter you will not get any kind of error and all file will be compiled successfully:
Now download other source code also from https://github.com/rmtheis/tess-two , and extract and import it and give it name OCRTest, like in my PC which is in D:\Android Workspace\OCRTest
Import test-two in this and run OCRTest and run it; you will get the best example of OCR.
You can also use below code
$request->request->set(key, value).
Fits better for me.
For me the scrollTop way did not work, but I found other:
element.style.display = 'none';
setTimeout(function() { element.style.display = 'block' }, 100);
Did not check the minimum time for reliable css rendering though, 100ms might be overkill.
If you want to know the number of visitors (as is titled in the question) and not the number of pageviews, then you'll need to create a custom report.
Google Analytics has changed the terminology they use within the reports. Now, visits is named "sessions" and unique visitors is named "users."
User - A unique person who has visited your website. Users may visit your website multiple times, and they will only be counted once.
Session - The number of different times that a visitor came to your site.
Pageviews - The total number of pages that a user has accessed.
Try C# string interpolation introduced in C# 6:
var id = 100;
var hexid = $"0x{id:X}";
hexid value:
"0x64"
del
statement does not delete an instance, it merely deletes a name.When you do del i
, you are deleting just the name i - but the instance is still bound to some other name, so it won't be Garbage-Collected.
If you want to release memory, your dataframes has to be Garbage-Collected, i.e. delete all references to them.
If you created your dateframes dynamically to list, then removing that list will trigger Garbage Collection.
>>> lst = [pd.DataFrame(), pd.DataFrame(), pd.DataFrame()]
>>> del lst # memory is released
>>> a, b, c = pd.DataFrame(), pd.DataFrame(), pd.DataFrame()
>>> lst = [a, b, c]
>>> del a, b, c # dfs still in list
>>> del lst # memory release now
If you are using Anaconda, all you have to do is activate your virtual environment and then install geckodriver using the following command:
conda install -c conda-forge geckodriver
Validate your email address format. [email protected]
public boolean emailValidator(String email)
{
Pattern pattern;
Matcher matcher;
final String EMAIL_PATTERN = "^[_A-Za-z0-9-]+(\\.[_A-Za-z0-9-]+)*@[A-Za-z0-9]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$";
pattern = Pattern.compile(EMAIL_PATTERN);
matcher = pattern.matcher(email);
return matcher.matches();
}
you can do:
adb pull /storage/emulated/0/Android/data//
You may be victim of a garbage collection problem.
When your application requires memory and it's getting low on what it's configured to use the garbage collector will run often which consume a lot of CPU cycles. If it can't collect anything your memory will stay low so it will be run again and again. When you redeploy your application the memory is cleared and the garbage collection won't happen more than required so the CPU utilization stays low until it's full again.
You should check that there is no possible memory leak in your application and that it's well configured for memory (check the -Xmx
parameter, see What does Java option -Xmx stand for?)
Also, what are you using as web framework? JSF relies a lot on sessions and consumes a lot of memory, consider being stateless at most!
In my index.php I'm loading maybe foobarfunc() like this:
foobar::foobarfunc(); // Wrong, it is not static method
but can also be
$foobar = new foobar; // correct
$foobar->foobarfunc();
You can not invoke method this way because it is not static method.
foobar::foobarfunc();
You should instead use:
foobar->foobarfunc();
If however you have created a static method something like:
static $foo; // your top variable set as static
public static function foo() {
return self::$foo;
}
then you can use this:
foobar::foobarfunc();
If you're wanting this as a script, the following Bash script should do what you want (plus tell you when the file already exists):
#!/bin/bash
if [ -e $1 ]; then
echo "File $1 already exists!"
else
echo >> $1
fi
If you don't want the "already exists" message, you can use:
#!/bin/bash
if [ ! -e $1 ]; then
echo >> $1
fi
Edit about using:
Save whichever version with a name you like, let's say "create_file" (quotes mine, you don't want them in the file name). Then, to make the file executatble, at a command prompt do:
chmod u+x create_file
Put the file in a directory in your path, then use it with:
create_file NAME_OF_NEW_FILE
The $1 is a special shell variable which takes the first argument on the command line after the program name; i.e. $1 will pick up NAME_OF_NEW_FILE in the above usage example.
Boost is a good suggestion. But if you would like to roll your own, it's not so hard.
Basically you just need a way to build up a graph of objects and then output them to some structured storage format (JSON, XML, YAML, whatever). Building up the graph is as simple as utilizing a marking recursive decent object algorithm and then outputting all the marked objects.
I wrote an article describing a rudimentary (but still powerful) serialization system. You may find it interesting: Using SQLite as an On-disk File Format, Part 2.
You can easily do this
const shopId = new URLSearchParams(window.location.search).get('shop_id');
console.log(shopId);
You could try using Path.IsPathRooted() in combination with Path.GetInvalidFileNameChars() to make sure the path is half-way okay.
UPDATE dummy SET myfield=1 WHERE id>1;
I dissent from both the answers. Don't create a reference at all, but use late binding:
Dim objExcelApp As Object
Dim wb As Object
Sub Initialize()
Set objExcelApp = CreateObject("Excel.Application")
End Sub
Sub ProcessDataWorkbook()
Set wb = objExcelApp.Workbooks.Open("path to my workbook")
Dim ws As Object
Set ws = wb.Sheets(1)
ws.Cells(1, 1).Value = "Hello"
ws.Cells(1, 2).Value = "World"
'Close the workbook
wb.Close
Set wb = Nothing
End Sub
You will note that the only difference in the code above is that the variables are all declared as objects and you instantiate the Excel instance with CreateObject().
This code will run no matter what version of Excel is installed, while using a reference can easily cause your code to break if there's a different version of Excel installed, or if it's installed in a different location.
Also, the error handling could be added to the code above so that if the initial instantiation of the Excel instance fails (say, because Excel is not installed or not properly registered), your code can continue. With a reference set, your whole Access application will fail if Excel is not installed.
For this problem, I have finally put a new <i>
tag to refresh the select instead. Don't try to trigger an event if the selected option is the same that the one already selected.
If user click on the "refresh" button, I trigger the onchange event of my select with :
const refreshEquipeEl = document.getElementById("refreshEquipe1");
function onClickRefreshEquipe(event){
let event2 = new Event('change');
equipesSelectEl.dispatchEvent(event2);
}
refreshEquipeEl.onclick = onClickRefreshEquipe;
This way, I don't need to try select the same option in my select.
This worked for me: :)
<button (click)="updatePendingApprovals(''+pendingApproval.personId, ''+pendingApproval.personId)">Approve</button>
updatePendingApprovals(planId: string, participantId: string) : void {
alert('PlanId:' + planId + ' ParticipantId:' + participantId);
}
I used deleteDir() as follows:
post {
always {
deleteDir() /* clean up our workspace */
}
}
However, I then had to also run a Success or Failure AFTER always but you cannot order the post conditions. The current order is always, changed, aborted, failure, success and then unstable.
However, there is a very useful post condition, cleanup which always runs last, see https://jenkins.io/doc/book/pipeline/syntax/
So in the end my post was as follows :
post {
always {
}
success{
}
failure {
}
cleanup{
deleteDir()
}
}
Hopefully this may be helpful for some corner cases
This alternative example stores the local time as Integer to save the 20 bytes. The work is done in the field default, Update-trigger, and View. strftime must use '%s' (single-quotes) because "%s" (double-quotes) threw a 'Not Constant' error on me.
Create Table Demo (
idDemo Integer Not Null Primary Key AutoIncrement
,DemoValue Text Not Null Unique
,DatTimIns Integer(4) Not Null Default (strftime('%s', DateTime('Now', 'localtime'))) -- get Now/UTC, convert to local, convert to string/Unix Time, store as Integer(4)
,DatTimUpd Integer(4) Null
);
Create Trigger trgDemoUpd After Update On Demo Begin
Update Demo Set
DatTimUpd = strftime('%s', DateTime('Now', 'localtime')) -- same as DatTimIns
Where idDemo = new.idDemo;
End;
Create View If Not Exists vewDemo As Select -- convert Unix-Times to DateTimes so not every single query needs to do so
idDemo
,DemoValue
,DateTime(DatTimIns, 'unixepoch') As DatTimIns -- convert Integer(4) (treating it as Unix-Time)
,DateTime(DatTimUpd, 'unixepoch') As DatTimUpd -- to YYYY-MM-DD HH:MM:SS
From Demo;
Insert Into Demo (DemoValue) Values ('One'); -- activate the field Default
-- WAIT a few seconds --
Insert Into Demo (DemoValue) Values ('Two'); -- same thing but with

Once you have the source trees, e.g.
diff -ENwbur repos1/ repos2/
Even better
diff -ENwbur repos1/ repos2/ | kompare -o -
and have a crack at it in a good gui tool :)
This will Helpfull.Easy to implement,100% tested.
for(int i=1;i<linecount;i++)

int presentage = (i * 100) / linecount;
LabelPresentage.Text = presentage.ToString() + " %"; //show precentage in lable
Application.DoEvents(); keep form active in every loop

Swift will not allow you to initialise super class with out initialising the properties, reverse of Obj C. So you have to initialise all properties before calling "super.init".
Please go to http://blog.scottlogic.com/2014/11/20/swift-initialisation.html. It gives a nice explanation to your problem.
Use SELECT COUNT(*) FROM t WHERE a = current_a AND c = 'const' ) as d
.
This worked for me.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button btnSendSMS = (Button) findViewById(R.id.btnSendSMS);
btnSendSMS.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
sendSMS("5556", "Hi You got a message!");
/*here i can send message to emulator 5556. In Real device
*you can change number*/
}
});
}
//Sends an SMS message to another device
private void sendSMS(String phoneNumber, String message) {
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(phoneNumber, null, message, null, null);
}
You can add this line in AndroidManifest.xml

This may be helpful for you.
One good solution is to run only desired services like this:
docker-compose up --build $(<services.txt)
and services.txt file look like this:
services1 services2, etc
of course if dependancy (depends_on), need to run related services together.
--build is optional, just for example.
I entirely agree that goto
is poor poor coding, but no one has actually answered the question. There is in fact a goto module for Python (though it was released as an April fool joke and is not recommended to be used, it does work).
Copy your XML schema here & get the JSON schema code to the online tools which are available to generate JSON schema from XML schema.
You can avoid the loop and cut etc by using:
awk -F ':' '{system("ping " $1);}' config.txt
However it would be better if you post a snippet of your config.txt
In basic terms synchronous requests wait for the response to be received from the request before it allows any code processing to continue. At first this may seem like a good thing to do, but it absolutely is not.
As mentioned, while the request is in process the browser will halt execution of all script and also rendering of the UI as the JS engine of the majority of browsers is (effectively) single-threaded. This means that to your users the browser will appear unresponsive and they may even see OS-level warnings that the program is not responding and to ask them if its process should be ended. It's for this reason that synchronous JS has been deprecated and you see warnings about its use in the devtools console.
The alternative of asynchronous requests is by far the better practice and should always be used where possible. This means that you need to know how to use callbacks and/or promises in order to handle the responses to your async requests when they complete, and also how to structure your JS to work with this pattern. There are many resources already available covering this, this, for example, so I won't go into it here.
There are very few occasions where a synchronous request is necessary. In fact the only one I can think of is when making a request within the beforeunload
event handler, and even then it's not guaranteed to work.
In summary. you should look to learn and employ the async pattern in all requests. Synchronous requests are now an anti-pattern which cause more issues than they generally solve.
Try IDLE, and use Alt + X to find indentation.
If you want to see the contents of RDD then yes collect is one option, but it fetches all the data to driver so there can be a problem
<rdd.name>.take(<num of elements you want to fetch>)
Better if you want to see just a sample
Running foreach and trying to print, I dont recommend this because if you are running this on cluster then the print logs would be local to the executor and it would print for the data accessible to that executor. print statement is not changing the state hence it is not logically wrong. To get all the logs you will have to do something like
**Pseudocode**
collect
foreach print
But this may result in job failure as collecting all the data on driver may crash it. I would suggest using take command or if u want to analyze it then use sample collect on driver or write to file and then analyze it.
I ran into this error when I tried generating migrations for a single app which had existing malformed migrations due to a git merge. e.g.
manage.py makemigrations myapp
When I deleted it's migrations and then ran:
manage.py makemigrations
the error did not occur and the migrations generated successfully.
This does what you want, I think:
git log --all --pretty=format: --name-only --diff-filter=D | sort -u
... which I've just taken more-or-less directly from this other answer.
You can just add the overflow:auto option:
#second
{

height:100%;
overflow: auto;
background-color:#9ACD32;
}
You should use the OO interface to matplotlib, rather than the state machine interface. Almost all of the plt.*
function are thin wrappers that basically do gca().*
.
plt.subplot
returns an axes
object. Once you have a reference to the axes object you can plot directly to it, change its limits, etc.
import matplotlib.pyplot as plt
ax1 = plt.subplot(131)
ax1.scatter([1, 2], [3, 4])
ax1.set_xlim([0, 5])
ax1.set_ylim([0, 5])
ax2 = plt.subplot(132)
ax2.scatter([1, 2],[3, 4])
ax2.set_xlim([0, 5])
ax2.set_ylim([0, 5])
and so on for as many axes as you want.
or better, wrap it all up in a loop:
import matplotlib.pyplot as plt
DATA_x = ([1, 2],
[2, 3],
[3, 4])
DATA_y = DATA_x[::-1]
XLIMS = [[0, 10]] * 3
YLIMS = [[0, 10]] * 3
for j, (x, y, xlim, ylim) in enumerate(zip(DATA_x, DATA_y, XLIMS, YLIMS)):
ax = plt.subplot(1, 3, j + 1)
ax.scatter(x, y)
ax.set_xlim(xlim)
ax.set_ylim(ylim)
I'd set up your HTML like so:
<img src="../images/bottle.jpg" alt="bottle" class="thumbnails" id="bottle" />
Then use the following code:
<script>
var images = document.getElementsByTagName("img");
for(var i = 0; i < images.length; i++) {
var image = images[i];
image.onclick = function(event) {
window.location.href = this.id + '.html';
};
}
</script>
That assigns an onclick
event handler to every image on the page (this may not be what you want, you can limit it further if necessary) that changes the current page to the value of the images id
attribute plus the .html
extension. It's essentially the pure Javascript implementation of @JanPöschko's jQuery answer.
Session state is saved on the server, ViewState is saved in the page.
Session state is usually cleared after a period of inactivity from the user (no request happened containing the session id in the request cookies).
The view state is posted on subsequent post back in a hidden field.
I did not have rights to create functions but had text like
["blahblah012345679"]
And needed to extract the numbers out of the middle
Note this assumes the numbers are grouped together and not at the start and end of the string.
select substring(column_name,patindex('%[0-9]%', column_name),patindex('%[0-9][^0-9]%', column_name)-patindex('%[0-9]%', column_name)+1)
from table name
I prefer something more explicit:
component.html
<input #saveUserNameCheckBox
id="saveUserNameCheckBox"
type="checkbox"
[checked]="saveUsername"
(change)="onSaveUsernameChanged(saveUserNameCheckBox.checked)" />
component.ts
public saveUsername:boolean;
public onSaveUsernameChanged(value:boolean){
this.saveUsername = value;
}
When looking up your external IP address on a NATed host, quite a few answers suggest using HTTP based methods like ifconfig.me
eg:
$ curl ifconfig.me/ip
Over the years I have seen many of these sites come and go, I find this DNS based method more robust:
$ dig +short myip.opendns.com @resolver1.opendns.com
I have this handy alias in my ~/.bashrc
:
alias wip='dig +short myip.opendns.com @resolver1.opendns.com'
Use this. Beware of i's larger than 9, as these will require a char array with more than 2 elements to avoid a buffer overrun.
char c[2];
int i=1;
sprintf(c, "%d", i);
Acoording to RFC 2046 (Multipurpose Internet Mail Extensions):
The recommended action for an implementation that receives an
"application/octet-stream" entity is to simply offer to put the data in a file
So I'd go for that one.
If you want to change navbar title (not navbar back button title!) this code will be work.
self.navigationController.topViewController.title = @"info";
This should do it, let me know if you have trouble with it:
Sub foo()
Dim x As Workbook
Dim y As Workbook
'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")
'Now, copy what you want from x:
x.Sheets("name of copying sheet").Range("A1").Copy
'Now, paste to y worksheet:
y.Sheets("sheetname").Range("A1").PasteSpecial
'Close x:
x.Close
End Sub
Alternatively, you could just:
Sub foo2()
Dim x As Workbook
Dim y As Workbook
'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")
'Now, transfer values from x to y:
y.Sheets("sheetname").Range("A1").Value = x.Sheets("name of copying sheet").Range("A1")
'Close x:
x.Close
End Sub
To extend this to the entire sheet:
With x.Sheets("name of copying sheet").UsedRange
'Now, paste to y worksheet:
y.Sheets("sheet name").Range("A1").Resize( _
.Rows.Count, .Columns.Count) = .Value
End With
And yet another way, store the value as a variable and write the variable to the destination:
Sub foo3()
Dim x As Workbook
Dim y As Workbook
Dim vals as Variant
'## Open both workbooks first:

The last method above is usually the fastest for most applications, but do note that for very large datasets (100k rows) it's observed that the Clipboard actually outperforms the array dump:
Copy/PasteSpecial vs Range.Value = Range.Value
That said, there are other considerations than just speed, and it may be the case that the performance hit on a large dataset is worth the tradeoff, to avoid interacting with the Clipboard.
Now You can access the InputField's state which is the child of FormEditor .
Basically whenever there is a change in the state of the input field(child) we are getting the value from the event object and then passing this value to the Parent where in the state in the Parent is set.
On button click we are just printing the state of the Input fields.
The key point here is that we are using the props to get the Input Field's id/value and also to call the functions which are set as attributes on the Input Field while we generate the reusable child Input fields.
class InputField extends React.Component{
handleChange = (event)=> {
const val = event.target.value;
this.props.onChange(this.props.id , val);
}
render() {
return(
<div>
<input type="text" onChange={this.handleChange} value={this.props.value}/>
<br/><br/>
</div>
);
}
}
class FormEditorParent extends React.Component {
state = {};
handleFieldChange = (inputFieldId , inputFieldValue) => {
this.setState({[inputFieldId]:inputFieldValue});
}
//on Button click simply get the state of the input field
handleClick = ()=>{
console.log(JSON.stringify(this.state));
}
render() {
const fields = this.props.fields.map(field => (
<InputField
key={field}
id={field}
onChange={this.handleFieldChange}
value={this.state[field]}
/>
));
return (
<div>
<div>
<button onClick={this.handleClick}>Click Me</button>
</div>
<div>
{fields}
</div>
</div>
);
}
}
const App = () => {
const fields = ["field1", "field2", "anotherField"];
return <FormEditorParent fields={fields} />;
};
ReactDOM.render(<App/>, mountNode);
If you need a PEM file without any password you can use this solution.
Just copy and paste the private key and the certificate to the same file and save as .pem.
The file will look like:
-----BEGIN PRIVATE KEY-----
............................
............................
-----END PRIVATE KEY-----
-----BEGIN CERTIFICATE-----
...........................
...........................
-----END CERTIFICATE-----
That's the only way I found to upload certificates to Cisco devices for HTTPS.
After inspecting closely, looks like both of you are using closure.
In your friends case, i
is accessed inside anonymous function 1 and i2
is accessed in anonymous function 2 where the console.log
is present.
In your case you are accessing i2
inside anonymous function where console.log
is present. Add a debugger;
statement before console.log
and in chrome developer tools under "Scope variables" it will tell under what scope the variable is.
Media types do not allow you to detect touch capabilities as part of the standard:
http://www.w3.org/TR/css3-mediaqueries/
So, there is no way to do it consistently via CSS or media queries, you will have to resort to JavaScript.
No need to use Modernizr, you can just use plain JavaScript:
<script type="text/javascript">
var is_touch_device = 'ontouchstart' in document.documentElement;
if(is_touch_device) alert("touch is enabled!");
</script>
Explaining how you can use cut
:
cat yourxmlfile | cut -d'"' -f2
It will 'cut' all the lines in the file based on " delimiter, and will take the 2nd field , which is what you wanted.
The Excel number for a modern date is most easily calculated as the number of days since 12/30/1899 on the Gregorian calendar.
Excel treats the mythical date 01/00/1900 (i.e., 12/31/1899) as corresponding to 0, and incorrectly treats year 1900 as a leap year. So for dates before 03/01/1900, the Excel number is effectively the number of days after 12/31/1899.
However, Excel will not format any number below 0 (-1 gives you ##########) and so this only matters for "01/00/1900" to 02/28/1900, making it easier to just use the 12/30/1899 date as a base.
A complete function in DB2 SQL that accounts for the leap year 1900 error:
SELECT
DAYS(INPUT_DATE)
- DAYS(DATE('1899-12-30'))
- CASE
WHEN INPUT_DATE < DATE('1900-03-01')
THEN 1
ELSE 0
END
I have had this problem and I consider we are missing a well explained way of doing this programmatically without losing the already set filters.
Setting the length in XML:
As the accepted answer states correctly, if you want to define a fixed length to an EditText which you won't change further in the future just define in your EditText XML:
android:maxLength="10"
Setting the length programmatically
To set the length programmatically you'll need to set it through an InputFilter
. But if you create a new InputFilter and set it to the EditText
you will lose all the other already defined filters (e.g. maxLines, inputType, etc) which you might have added either through XML or programatically.
So this is WRONG:
editText.setFilters(new InputFilter[] {new InputFilter.LengthFilter(maxLength)});
To avoid losing previously added filters you need to get those filters, add the new one (maxLength in this case), and set the filters back to the EditText
as follow:
Java
InputFilter[] editFilters = editText.getFilters();
InputFilter[] newFilters = new InputFilter[editFilters.length + 1];
System.arraycopy(editFilters, 0, newFilters, 0, editFilters.length);
newFilters[editFilters.length] = new InputFilter.LengthFilter(maxLength);
editText.setFilters(newFilters);
Kotlin however made it easier for everyone, you also need to add the filter to the already existing ones but you can achieve that with a simple:
editText.filters += InputFilter.LengthFilter(maxLength)
My two cents to the previous answers: if
git push --force <remote> <the-hash>:<the remote branch>
still doesn't work, you might want to edit <your-remote-repo>.git/config
file's receive section:
[receive]
#denyNonFastforwards = true
denyNonFastforwards = false
XML Schemas describe hierarchial data models and may not map well to a relational data model. Mapping XSD's to database tables is very similar mapping objects to database tables, in fact you could use a framework like Castor that does both, it allows you to take a XML schema and generate classes, database tables, and data access code. I suppose there are now many tools that do the same thing, but there will be a learning curve and the default mappings will most like not be what you want, so you have to spend time customizing whatever tool you use.
XSLT might be the fastest way to generate exactly the code that you want. If it is a small schema hardcoding it might be faster than evaluating and learing a bunch of new technologies.
It means the path you input caused an error. In your LD_PRELOAD

Groovy accepts nearly all Java syntax, so there is a spectrum of choices, as illustrated below:
// Java syntax
Map<String,List> map1 = new HashMap<>();
List list1 = new ArrayList();
list1.add("hello");
map1.put("abc", list1);
assert map1.get("abc") == list1;
// slightly less Java-esque
def map2 = new HashMap<String,List>()
def list2 = new ArrayList()
list2.add("hello")
map2.put("abc", list2)
assert map2.get("abc") == list2
// typical Groovy
def map3 = [:]
def list3 = []
list3 << "hello"
map3.'abc'= list3
assert map3.'abc' == list3
It is simple , remove the code that you have used and use the below code :
const url = 'mongodb://localhost:27017';
var dbConn = mongodb.MongoClient.connect(url, {useUnifiedTopology: true});
I think all the above do not answer this question due to following reasons,
but none has told the exact reason behind it & as I believe these kind of questions can be best answered by java community itself as it will have only one & specific answer but let me try my best to answer this as following,
As we know sorting is an expensive operation and there is a basic difference between List & Set/Map that List can have duplicates but Set/Map can not. This is the core reason why we have got a default implementation for Set/Map in form of TreeSet/TreeMap. Internally this is a Red Black Tree with every operation (insert/delete/search) having the complexity of O(log N) where due to duplicates List could not fit in this data storage structure.
Now the question arises we could also choose a default sorting method for List also like MergeSort which is used by Collections.sort(list)
method with the complexity of O(N log N). Community did not do this deliberately since we do have multiple choices for sorting algorithms for non distinct elements like QuickSort, ShellSort, RadixSort...etc. In future there can be more. Also sometimes same sorting algorithm performs differently depending on the data to be sorted. Therefore they wanted to keep this option open and left this on us to choose. This was not the case with Set/Map since O(log N) is the best sorting complexity.
I think there are a few things to understand when working with API Gateway integration with Lambda.
There used to be only Lambda Integration which requires mapping templates. I suppose this is why still seeing many examples using it.
As of September 2017, you no longer have to configure mappings to access the request body.
Lambda Proxy Integration, If you enable it, API Gateway will map every request to JSON and pass it to Lambda as the event object. In the Lambda function you’ll be able to retrieve query string parameters, headers, stage variables, path parameters, request context, and the body from it.
Without enabling Lambda Proxy Integration, you’ll have to create a mapping template in the Integration Request section of API Gateway and decide how to map the HTTP request to JSON yourself. And you’d likely have to create an Integration Response mapping if you were to pass information back to the client.
Before Lambda Proxy Integration was added, users were forced to map requests and responses manually, which was a source of consternation, especially with more complex mappings.
Words need to navigate the thinking. To get the terminologies straight.
Lambda Proxy Integration = Pass through
Simply pass the HTTP request through to lambda.
Lambda Integration = Template transformation
Go through a transformation process using the Apache Velocity template and you need to write the template by yourself.
Using Lambda Proxy Integration, the body in the event of lambda is a string escaped with backslash, not a JSON.
"body": "{\"foo\":\"bar\"}"
If tested in a JSON formatter.
Parse error on line 1:
{\"foo\":\"bar\"}
-^
Expecting 'STRING', '}', got 'undefined'
The document below is about response but it should apply to request.
The body field, if you are returning JSON, must be converted to a string or it will cause further problems with the response. You can use JSON.stringify to handle this in Node.js functions; other runtimes will require different solutions, but the concept is the same.
For JavaScript to access it as a JSON object, need to convert it back into JSON object with json.parse in JapaScript, json.dumps in Python.
Strings are useful for transporting but you’ll want to be able to convert them back to a JSON object on the client and/or the server side.
The AWS documentation shows what to do.
if (event.body !== null && event.body !== undefined) {
let body = JSON.parse(event.body)
if (body.time)
time = body.time;
}
...
var response = {
statusCode: responseCode,
headers: {
"x-custom-header" : "my custom header value"
},
body: JSON.stringify(responseBody)
};
console.log("response: " + JSON.stringify(response))
callback(null, response);
The difference is that concatenate will flatten the resulting list, whereas append will keep the levels intact:
So for example with:
myList = [ ]
listA = [1,2,3]
listB = ["a","b","c"]
Using append, you end up with a list of lists:
>> myList.append(listA)
>> myList.append(listB)
>> myList
[[1,2,3],['a',b','c']]
Using concatenate instead, you end up with a flat list:
>> myList += listA + listB
>> myList
[1,2,3,"a","b","c"]

Notice that we haven't even gotten to any code yet, this is just to get to the first actual bit of code. This actually happens (in almost, but not exactly the same way) for several functions, each of which, in the end only have 4 possible variations (which are also mostly copy/paste with slight variations and #ifdefs of their own).
The
(condition) ? /* value to return if condition is true */
: /* value to return if condition is false */ ;
syntax is not a "shorthand if" operator (the ?
is called the conditional operator) because you cannot execute code in the same manner as if you did:
if (condition) {
/* condition is true, do something like echo */
}
else {
/* condition is false, do something else */
}
In your example, you are executing the echo
statement when the $address
is not empty. You can't do this the same way with the conditional operator. What you can do however, is echo
the result of the conditional operator:
echo empty($address['street2']) ? "Street2 is empty!" : $address['street2'];
and this will display "Street is empty!" if it is empty, otherwise it will display the street2 address.
echo $fspec | tr "/" "\n"|tail -1
You can also use openssl
to accomplish the same thing:
$ openssl pkcs12 -nokeys -info \
-in </path/to/file.pfx> \
-passin pass:<pfx's password>

On Windows, line.separator is a CR/LF combination (reference here).
The Java String.split()
method takes a regular expression. So I think there's some confusion here.
You could do something like this in a loop based on the number of text fields they enter.
$('<input/>').attr({type:'text',name:'text'+i}).appendTo('#myform');
But for better performance I'd create all the html first and inject it into the DOM only once.
var count = 20;
var html = [];
while(count--) {
html.push("<input type='text' name='name", count, "'>");
}
$('#myform').append(html.join(''));
Edit this example uses jQuery to append the html, but you could easily modify it to use innerHTML as well.
You can find the instructions here. Basically you just add
[global]
http-proxy-host = ip.add.re.ss
http-proxy-port = 3128
http-proxy-compression = no
to your ~/.subversion/servers
file.
The problem is that [...]
in python has two distinct meanings
expr [ index ]
means accessing an element of a list[ expr1, expr2, expr3 ]
means building a list of three elements from three expressionsIn your code you forgot the comma between the expressions for the items in the outer list:
[ [a, b, c] [d, e, f] [g, h, i] ]
therefore Python interpreted the start of second element as an index to be applied to the first and this is what the error message is saying.
The correct syntax for what you're looking for is
[ [a, b, c], [d, e, f], [g, h, i] ]
new String(byteArray, 0, bytesRead);
does not modify the array. You need to use System.arrayCopy
to trim the array to the actual data size. Otherwise you are processing all 102400 bytes most of which are zeros.
Like @itsneo said, I personally find ? + [ and ] the most convenient ones on a mac. But I can understand if you come from Linux side of things. Then you can use ? + alt + ? or ?.
I would strongly recommend that you bundle the DateJS library with your plugin and document the fact that you've done it. Nothing is more frustrating than having to hunt down dependencies.
That said, for legal reasons, you may not always be able to bundle everything. It also never hurts to be cautious and check for the existence of the plugin using Eran Galperin's answer.
While it's ok to use inline styles, your purposes may better be served by including an external CSS file on the page. This way you could define a class of image (i.e. 'Thumbnail', 'Photo', 'Large', etc) and assign it a constant size. This will help when you end up with images requiring the same placement across multiple pages.
Like this:
In your header: <link type="text/css" rel="stylesheet" href="css/style.css" /> Your HTML: <img class="thumbnail" src="images/academia_vs_business.png" alt="" /> In css/style.css: img.thumbnail { width: 75px; height: 75px; }
If you'd like to use inline styles though, it's probably best to set the width and height using the style attribute for the sake of readability.
// apparently this is broken. Whoops for me!
java.util.Collections.fill(list,new Integer(0));
// this is better
Integer[] data = new Integer[60];
Arrays.fill(data,new Integer(0));
List<Integer> list = Arrays.asList(data);
Adding a twist to Alphii answer, actually the for loop would be second best and about 6 times slower than map
from functools import reduce
import datetime
def time_it(func, numbers, *args):
start_t = datetime.datetime.now()
for i in range(numbers):
func(args[0])
print (datetime.datetime.now()-start_t)
def square_sum1(numbers):
return reduce(lambda sum, next: sum+next**2, numbers, 0)
def square_sum2(numbers):
a = 0
for i in numbers:
a += i**2
return a
def square_sum3(numbers):
a = 0
map(lambda x: a+x**2, numbers)
return a
def square_sum4(numbers):
a = 0
return [a+i**2 for i in numbers]
time_it(square_sum1, 100000, [1, 2, 5, 3, 1, 2, 5, 3])
time_it(square_sum2, 100000, [1, 2, 5, 3, 1, 2, 5, 3])
time_it(square_sum3, 100000, [1, 2, 5, 3, 1, 2, 5, 3])
time_it(square_sum4, 100000, [1, 2, 5, 3, 1, 2, 5, 3])
Main changes have been to eliminate the slow sum
calls, as well as the probably unnecessary int()
in the last case. Putting the for loop and map in the same terms makes it quite fact, actually. Remember that lambdas are functional concepts and theoretically shouldn't have side effects, but, well, they can have side effects like adding to a
.
Results in this case with Python 3.6.1, Ubuntu 14.04, Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz
0:00:00.257703 #Reduce
0:00:00.184898 #For loop

You can use result.className = 'red';
, but you can also use result.classList.add('red');
. The .classList.add(str)
way is usually easier if you need to add a class in general, and don't want to check if the class is already in the list of classes.
Here's a function to pretty up your json: pretty_json
Full version:
<? echo date('F Y'); ?>
Short version:
<? echo date('M Y'); ?>
Here is a good reference for the different date options.
update
To show the previous month we would have to introduce the mktime() function and make use of the optional timestamp
parameter for the date() function. Like this:
echo date('F Y', mktime(0, 0, 0, date('m')-1, 1, date('Y')));
This will also work (it's typically used to get the last day of the previous month):
echo date('F Y', mktime(0, 0, 0, date('m'), 0, date('Y')));
Hope that helps.
You can also produce array by using file:
$array = file('/path/to/text.txt');
Of course you can write "something" a bit better to keep maintenance:
#include <iostream>
#include <cstdlib>
using namespace std;
class Something
{
public:
Something(int x, int y, int z) : a(x), b(y), c(z) { }
int a;
int b;
int c;
friend ostream& operator<<(ostream&, const Something&);
void print() const { printf("%i, %i, %i\n", a, b, c); }
};
ostream& operator<<(ostream& o, const Something& s)
{
o << s.a << ", " << s.b << ", " << s.c;
return o;
}
int main(void)
{
Something s(3, 2, 1);
// Output with printf
s.print(); // Simple as well, isn't it?
// Output with cout
cout << s << endl;
return 0;
}
And a bit extended test of cout vs. printf, added a test of 'double', if anyone wants to do more testing (Visual Studio 2008, release version of the executable):
#include <stdio.h>
#include <iostream>
#include <ctime>

I found some articles to be of major use:
This link is an experience someone else had: http://goneale.com/2009/05/24/cant-install-microsoft-sql-server-2008-management-studio-express/
This link has the exact steps involved to install everything properly: http://www.codefrenzy.net/2011/06/03/how-to-install-sql-server-2008-management-studio/
This link confirms the previous link: https://superuser.com/questions/88244/installing-sql-server-management-studio-when-vs2010-beta-2-is-already-installed
My Instructions
I am not sure if my instructions will be 100% accurate, but in my instance, because I installed VS2010 on a fresh copy of Windows 7, the VS2010 installer installs SQL Server 2008 Express for you, so from this point I just need the Management Studio.
What I gathered from these explanations is to do the following:
Download the SQL Server Management Studio install from http://www.microsoft.com/download/en/details.aspx?id=22973
Run the setup, when you get to the point where it asks you to "Perform a new installation of SQL Server 2008" or "Add features to an existing instance of SQL Server 2008", this part is the CONFUSING PART (HEY MICROSOFT TAKE NOTES, DON'T DO THIS KIND OF STUFF).
As much as you want to select "Add features to an existing instance of SQL Server 2008" DON'T!!!!
You need to select "Perform a new installation of SQL Server 2008". It doesn't sound right I know - it is very confusing and counter intuitive, but this seems to be the way to install management studio. :(
Press next until you see the features selection portion. Heeeeeyyyy look at that, it has a check box for Management Studio. It should be selected already, if not then select it of course and press next.
Press Next next next next next next... basically just install it at this point.
Enjoy, it has installed.

Yes there is a difference between the functions but the way you are using them in this case will result in the same outcome.
path.join
returns a normalized path by merging two paths together. It can return an absolute path, but it doesn't necessarily always do so.
For instance:
path.join('app/libs/oauth', '/../ssl')
resolves to app/libs/ssl
path.resolve
, on the other hand, will resolve to an absolute path.
For instance, when you run:
path.resolve('bar', '/foo');
The path returned will be /foo
since that is the first absolute path that can be constructed.
However, if you run:
path.resolve('/bar/bae', '/foo', 'test');
The path returned will be /foo/test
again because that is the first absolute path that can be formed from right to left.
If you don't provide a path that specifies the root directory then the paths given to the resolve
function are appended to the current working directory. So if your working directory was /home/mark/project/
:
path.resolve('test', 'directory', '../back');
resolves to
/home/mark/project/test/back
Using __dirname
is the absolute path to the directory containing the source file. When you use path.resolve
or path.join
they will return the same result if you give the same path following __dirname
. In such cases it's really just a matter of preference.
In cell A1, enter the time.
In cell B2, enter =A1+1/24
What I've done to solve the same problem is to have a feature detection (I use something like this code), seeing if onTouchMove is defined, and if so I add the css class "touchMode" to the body, else i add "desktopMode".
Then every time some style effect only applies to a touch device, or only to a desktop the css rule is prepended with the appropriate class:
.desktopMode .someClass:hover{ color: red }
.touchMode .mainDiv { width: 100%; margin: 0; /*etc.*/ }
Edit: This strategy of course adds a few extra characters to your css, so If you're concerned about css size, you could search for the touchMode and desktopMode definitons and put them into different files, so you can serve optimized css for each device type; or you could change the class names to something much shorter before going to prod.
I'm putting this in a new answer because no linebreaks / codeblocks in comments. I assume you want those nans to turn into a blank string? I couldn't find a nice way to do this, only do the ugly method:
s = pd.Series([1001.,1002.,None])
a = s.loc[s.isnull()].fillna('')
b = s.loc[s.notnull()].astype(int).astype(str)
result = pd.concat([a,b])
You can take update / pull on git branch you can use below command
git pull origin <branch-name>
The above command will take an update/pull from giving branch name
If you want to take pull from another branch, you need to go to that branch.
git checkout master
Than
git pull origin development
Hope that will work for you
If someone views on my answer, you maybe in this condition:
1. Trying to get a map screenshot in canvas using openlayers (version >= 3)
2. And viewed the example of exporting map
3. Using ol.source.XYZ to render map layer
Bingo!
Using ol.source.XYZ.crossOrigin = 'Anonymous' to solve your confuse. Or like following code:
var baseLayer = new ol.layer.Tile({
name: 'basic',
source: new ol.source.XYZ({
url: options.baseMap.basic,
crossOrigin: "Anonymous"
})
});
Your code "for /f "tokens=* delims=" %%x in (a.txt) do echo %%x" will work on most Windows Operating Systems unless you have modified commands.
So you could instead "cd" into the directory to read from before executing the "for /f" command to follow out the string. For instance if the file "a.txt" is located at C:\documents and settings\%USERNAME%\desktop\a.txt then you'd use the following.
cd "C:\documents and settings\%USERNAME%\desktop"
for /f "tokens=* delims=" %%x in (a.txt) do echo %%x
echo.
echo.
echo.
pause >nul
exit
But since this doesn't work on your computer for x reason there is an easier and more efficient way of doing this. Using the "type" command.
@echo off
color a
cls
cd "C:\documents and settings\%USERNAME%\desktop"
type a.txt
echo.
echo.
pause >nul
exit
Or if you'd like them to select the file from which to write in the batch you could do the following.
@echo off
:A
color a
cls
echo Choose the file that you want to read.
echo.
echo.
tree
echo.
echo.
echo.
set file=
set /p file=File:
cls
echo Reading from %file%
echo.
type %file%
echo.
echo.
echo.
set re=
set /p re=Y/N?:
if %re%==Y goto :A
if %re%==y goto :A
exit
I assume you don't want leading/trailing space. This means you have to split the regex into "first character", "stuff in the middle" and "last character":
^[a-zA-Z0-9_][a-zA-Z0-9_ ]*[a-zA-Z0-9_]$
or if you use a perl-like syntax:
^\w[\w ]*\w$
Also: If you intentionally worded your regex that it also allows empty Strings, you have to make the entire thing optional:
^(\w[\w ]*\w)?$
If you want to only allow single space chars, it looks a bit different:
^((\w+ )*\w+)?$
This matches 0..n words followed by a single space, plus one word without space. And makes the entire thing optional to allow empty strings.

Plotly's R API might be useful for you. The graph below is here.
library(plotly)
#add username and key
p <- plotly(username="Username", key="API_KEY")
#generate data
x0 = rnorm(500)
x1 = rnorm(500)+1
#arrange your graph
data0 = list(x=x0,
name = "Carrots",
type='histogramx',
opacity = 0.8)
data1 = list(x=x1,
name = "Cukes",
type='histogramx',
opacity = 0.8)
#specify type as 'overlay'
layout <- list(barmode='overlay',
plot_bgcolor = 'rgba(249,249,251,.85)')
#format response, and use 'browseURL' to open graph tab in your browser.
response = p$plotly(data0, data1, kwargs=list(layout=layout))
url = response$url
filename = response$filename
browseURL(response$url)
Full disclosure: I'm on the team.
You don't need to pass the quotes enclosing the custom headers to curl. Also, your variables in the middle of the data
argument should be quoted.
First, write a function that generates the post data of your script. This saves you from all sort of headaches concerning shell quoting and makes it easier to read an maintain the script than feeding the post data on curl's invocation line as in your attempt:
generate_post_data()
{
cat <<EOF
{
"account": {
"email": "$email",
"screenName": "$screenName",
"type": "$theType",
"passwordSettings": {
"password": "$password",
"passwordConfirm": "$password"
}
},
"firstName": "$firstName",
"lastName": "$lastName",
"middleName": "$middleName",
"locale": "$locale",
"registrationSiteId": "$registrationSiteId",
"receiveEmail": "$receiveEmail",
"dateOfBirth": "$dob",
"mobileNumber": "$mobileNumber",
"gender": "$gender",
"fuelActivationDate": "$fuelActivationDate",
"postalCode": "$postalCode",
"country": "$country",
"city": "$city",
"state": "$state",
"bio": "$bio",
"jpFirstNameKana": "$jpFirstNameKana",
"jpLastNameKana": "$jpLastNameKana",
"height": "$height",
"weight": "$weight",
"distanceUnit": "MILES",
"weightUnit": "POUNDS",
"heightUnit": "FT/INCHES"
}
EOF
}
It is then easy to use that function in the invocation of curl:
curl -i \
-H "Accept: application/json" \
-H "Content-Type:application/json" \
-X POST --data "$(generate_post_data)" "https://xxx:[email protected]/xxxxx/xxxx/xxxx"
This said, here are a few clarifications about shell quoting rules:
The double quotes in the -H
arguments (as in -H "foo bar"
) tell bash to keep what's inside as a single argument (even if it contains spaces).
The single quotes in the --data
argument (as in --data 'foo bar'
) do the same, except they pass all text verbatim (including double quote characters and the dollar sign).
To insert a variable in the middle of a single quoted text, you have to end the single quote, then concatenate with the double quoted variable, and re-open the single quote to continue the text: 'foo bar'"$variable"'more foo'
.
Use this:
style="height: 150px; max-height: 300px; overflow: auto;"
fixe a height, it will be the default height and then a scroll bar come to access to the entire height
Here is another way, by rotating element
with the scrollbar
for 180deg,
wrapping it's content
into another element, and rotating
that wrapper
for -180deg
.
Check the snippet below
div {_x000D_
display: inline-block;_x000D_
width: 100px;_x000D_
height: 100px;_x000D_

This should accomplish what you want to do. I just tested it on a sheet of mine; let me know if this doesn't work. LTrim is if you only have leading spaces; the Trim function can be used as well as it takes care of leading and trailing spaces. Replace the range of cells in the area I have as "A1:C50" and also make sure to change "Sheet1" to the name of the sheet you're working on.
Dim cell As Range, areaToTrim As Range
Set areaToTrim = Sheet1.Range("A1:C50")
For Each cell In areaToTrim
cell.Value = LTrim(cell.Value)
Next cell
If you're using SASS you could also use this mixin:
@mixin headings {
h1, h2, h3,
h4, h5, h6 {
@content;
}
}
Use it like so:
@include headings {
font: 32px/42px trajan-pro-1, trajan-pro-2;
}
Edit: My personal favourite way of doing this by optionally extending a placeholder selector on each of the heading elements.
h1, h2, h3,
h4, h5, h6 {
@extend %headings !optional;
}
Then I can target all headings like I would target any single class, for example:
.element > %headings {
color: red;
}
Starting from Python 3.1, you can use importlib :
import importlib
foobar = importlib.import_module("foo-bar")
According with the HTTP/1.1 standard, the shared IP hosted site can be accessed by a GET request with the IP as URL and a header of the host.
Here there are two examples(wget and curl):
$ wget --header 'Host:somerandomservice.com' http://67.225.235.59
$ curl --header 'Host:somerandomservice.com' http://67.225.235.59

Your dot is matching all characters. Escape it (and the other special characters), like this:
preg_replace('/[^a-zA-Z0-9_ %\[\]\.\(\)%&-]/s', '', $String);
Google's support answer on serving ads over SSL and the grammar in the RFC itself would seem to indicate that you can space delimit the URLs. Not sure how well-supported this is in different browsers.
For all that struggle with theoretical file paths and examples like I did, here a real world example: Microsoft offers their docs and examples on git hub, unfortunately they do gather all their example files for a large amount of topics in this repository:
https://github.com/microsoftarchive/msdn-code-gallery-community-s-z
I only was interested in the Microsoft Dynamics js files in the path
msdn-code-gallery-community-s-z/Sdk.Soap.js/
so I did the following
create a
msdn-code-gallery-community-s-zSdkSoapjs\.git\info\sparse-checkout
file in my repositories folder on the disk
git sparse-checkout init
in that directory using cmd on windows
The file contents of
msdn-code-gallery-community-s-zSdkSoapjs\.git\info\sparse-checkout
is
Sdk.Soap.js/*
finally do a
git pull origin master
First convert it to std::wstring:
std::wstring widestr = std::wstring(str.begin(), str.end());
Then get the C string:
const wchar_t* widecstr = widestr.c_str();
This only works for ASCII strings, but it will not work if the underlying string is UTF-8 encoded. Using a conversion routine like MultiByteToWideChar() ensures that this scenario is handled properly.
To retrieve tasks from backend, use this
from amqplib import client_0_8 as amqp
conn = amqp.Connection(host="localhost:5672 ", userid="guest",
password="guest", virtual_host="/", insist=False)
chan = conn.channel()
name, jobs, consumers = chan.queue_declare(queue="queue_name", passive=True)
You don't have any error in either of your queries. My guess is the following:
Perhaps you should check NLS_DATE_FORMAT
and use the date string conforming the format.
Or you can use to_date
function within the INSERT
statement, like the following:
insert into visit
values(123456,
to_date('19-JUN-13', 'dd-mon-yy'),
to_date('13-AUG-13 12:56 A.M.', 'dd-mon-yyyy hh:mi A.M.'));
Additionally, Oracle DATE
stores date and time information together.
Why don't you build a DataTable
first then assign it to the DataGridView
as DataSource
:
DataTable table4DataSource=new DataTable();
table4DataSource.Columns.Add("col00");
table4DataSource.Columns.Add("col01");
table4DataSource.Columns.Add("col02");
...
(add your rows, manually, in a circle or via a DataReader
from a database table)
(assign the datasource)
dtGrdViewGrid.DataSource = table4DataSource;
and then use:
(dtGrdViewGrid.DataSource as DataTable).DefaultView.RowFilter = "col00 = '" + textBoxSearch.Text+ "'";
dtGrdViewGrid.Refresh();
You can even put this piece of code within your textbox_textchange
event and your filtered values will be showing as you write.
From jquery prospective - it's just adding load
/onload
event to window and document.
Check this out:
I would suggest doing this in a more functional style :P
function CreateMessageboard(BoardMessages) {
var htmlMessageboardString = BoardMessages
.map(function(BoardMessage) {
return MessageToHTMLString(BoardMessage);
})
.join('');
}
Try this
By using Interceptor you can catch error. Below is code:
@Injectable()
export class ResponseInterceptor implements HttpInterceptor {
intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
//Get Auth Token from Service which we want to pass thr service call
const authToken: any = `Bearer ${sessionStorage.getItem('jwtToken')}`
// Clone the service request and alter original headers with auth token.
const authReq = req.clone({
headers: req.headers.set('Content-Type', 'application/json').set('Authorization', authToken)
});
const authReq = req.clone({ setHeaders: { 'Authorization': authToken, 'Content-Type': 'application/json'} });
// Send cloned request with header to the next handler.
return next.handle(authReq).do((event: HttpEvent<any>) => {
if (event instanceof HttpResponse) {
console.log("Service Response thr Interceptor");
}
}, (err: any) => {
if (err instanceof HttpErrorResponse) {
console.log("err.status", err);
if (err.status === 401 || err.status === 403) {
location.href = '/login';
console.log("Unauthorized Request - In case of Auth Token Expired");
}
}
});
}
}

There is an interesting "pure-swift" Open Source library:
CryptoSwift: https://github.com/krzyzanowskim/CryptoSwift
It supports: AES-128, AES-192, AES-256, ChaCha20
Example with AES decrypt (got from project README.md file):
import CryptoSwift
let setup = (key: keyData, iv: ivData)
let decryptedAES = AES(setup).decrypt(encryptedData)
I've spoken to Tab Atkins (author of the flexbox spec) about this, and this is what we came up with:
HTML:
<div class="content">
<div class="box">
<div class="column">Column 1</div>
<div class="column">Column 2</div>
<div class="column">Column 3</div>
</div>
</div>
CSS:
.content {
flex: 1;
display: flex;
overflow: auto;
}
.box {
display: flex;
min-height: min-content; /* needs vendor prefixes */
}
Here are the pens:
The reason this works is because align-items: stretch
doesn't shrink its items if they have an intrinsic height, which is accomplished here by min-content
.
If you using latest Owl Carousel 2 version. You can replace the Navigation text by fontawesome icon. Code is below.
$('.your-class').owlCarousel({
loop: true,
items: 1, // Select Item Number
autoplay:true,
dots: false,
nav: true,
navText: ["<i class='fa fa-long-arrow-left'></i>","<i class='fa fa-long-arrow-right'></i>"],
});
I know this is old question, but future references. In Android Studio with Gradle:
buildTypes {
release {
debuggable true
runProguard true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
The line debuggable true
was the trick for me.
Update:
Since gradle 1.0 it's minifyEnabled
instead of runProguard
. Look at here
What I have done is implement List having a internal instance with all the methods delegated.
public class ContactList implements List<Contact>, Serializable {
private static final long serialVersionUID = -1862666454644475565L;
private final List<Contact> list;
public ContactList() {
super();
this.list = new ArrayList<Contact>();
}
public ContactList(List<Contact> list) {
super();
//copy and order list
List<Contact>aux= new ArrayList(list);
Collections.sort(aux);
this.list = aux;
}
public void clear() {
list.clear();
}
public boolean contains(Object object) {
return list.contains(object);
}
After, I have implemented a new method "putOrdered" which insert in the proper position if the element doesn't exist or replace just in case it exist.
public void putOrdered(Contact contact) {
int index=Collections.binarySearch(this.list,contact);
if(index<0){
index= -(index+1);
list.add(index, contact);
}else{
list.set(index, contact);
}
}
If you want to allow repeated elements just implement addOrdered instead (or both).
public void addOrdered(Contact contact) {
int index=Collections.binarySearch(this.list,contact);
if(index<0){
index= -(index+1);
}
list.add(index, contact);
}
If you want to avoid inserts you can also throw and unsupported operation exception on "add" and "set" methods.
public boolean add(Contact object) {
throw new UnsupportedOperationException("Use putOrdered instead");
}
... and also You have to be careful with ListIterator methods because they could modify your internal list. In this case you can return a copy of the internal list or again throw an exception.
public ListIterator<Contact> listIterator() {
return (new ArrayList<Contact>(list)).listIterator();
}
Yet another possibility is the splitIndices
function from package parallel
:
library(parallel)
splitIndices(20, 3)
Gives:

[1] 8 9 10 11 12 13
[[3]]
[1] 14 15 16 17 18 19 20
Rabin-Miller is a standard probabilistic primality test. (you run it K times and the input number is either definitely composite, or it is probably prime with probability of error 4-K. (a few hundred iterations and it's almost certainly telling you the truth)
There is a non-probabilistic (deterministic) variant of Rabin Miller.
The Great Internet Mersenne Prime Search (GIMPS) which has found the world's record for largest proven prime (274,207,281 - 1 as of June 2017), uses several algorithms, but these are primes in special forms. However the GIMPS page above does include some general deterministic primality tests. They appear to indicate that which algorithm is "fastest" depends upon the size of the number to be tested. If your number fits in 64 bits then you probably shouldn't use a method intended to work on primes of several million digits.
I followed these instructions but then found that the menu hover color was wrong.
I am using the Spacegray theme in Sublime 3 beta 3074. So to accomplish the sidebar font color change and also hover color change, on OSX, I created a new file ~/Library/"Application Support"/"Sublime Text 3"/Packages/User/Spacegray.sublime-theme
then added this code to it:
[
{
"class": "sidebar_label",
"color": [192,197,203],
"font.bold": false,
"font.size": 15
},
{
"class": "sidebar_label",
"parents": [{"class": "tree_row","attributes": ["hover"]}],
"color": [255,255,255]
},
]
It is possible to tweak many other settings for your theme if you can see the original default:

I extracted this file from the sublime package zip file by installing the PackageResourceViewer following MattDMo's instructions (https://stackoverflow.com/users/1426065/mattdmo) here:

Function LogWrite
{

Then replace your Write-host

Please think really hard about if you do need to kill the application: why not let the OS figure out where and when to free the resources?
Otherwise, if you're absolutely really sure, use
finish();
As a reaction to @dave appleton's comment: First thing read the big question/answer combo @gabriel posted: Is quitting an application frowned upon?
Now assuming we have that, the question here still has an answer, being that the code you need if you are doing anything with quitting is finish()
. Obviously you can have more than one activity etc etc, but that's not the point. Lets run by some of the use-cases
So in the end, ofcourse, finish()
doesn't kill everthing, but it is still the tool you need I think. If there is a usecase for "kill all activities", I haven't found it yet.

use Date function directly. Hope it works
Contanis occur if using the method of the present letter, and store the corresponding number using the IndexOf method, see example below.
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim myString As String = "abcdef"
Dim numberString As String = String.Empty
If myString.Contains("d") Then
numberString = myString.IndexOf("d")
End If
End Sub
Another sample with TextBox
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim myString As String = "abcdef"
Dim numberString As String = String.Empty
If myString.Contains(me.TextBox1.Text) Then
numberString = myString.IndexOf(Me.TextBox1.Text)
End If
End Sub

You could let your DataAdapter
do the work. DataAdapter.Fill(DataTable)
will append your new rows to any existing rows in DataTable
.
For this format (supposed datepart has the format dd-mm-yyyy) in plain javascript:
var dt = '01-01-1970 00:03:44'.split(/\-|\s/)_x000D_
dat = new Date(dt.slice(0,3).reverse().join('/')+' '+dt[3]);
_x000D_
All strings meant for humans should use u"".
I found that the following mindset helps a lot when dealing with Python strings: All Python manifest strings should use the u""
syntax. The ""
syntax is for byte arrays, only.
Before the bashing begins, let me explain. Most Python programs start out with using ""
for strings. But then they need to support documentation off the Internet, so they start using "".decode
and all of a sudden they are getting exceptions everywhere about decoding this and that - all because of the use of ""
for strings. In this case, Unicode does act like a virus and will wreak havoc.
But, if you follow my rule, you won't have this infection (because you will already be infected).
I don't know what your exact problem is, but if you're receiving XML and want to return JSON (or something) you could also look at JAX-B. This is a standard for marshalling/unmarshalling Java POJO's to XML and/or Json. There are multiple libraries that implement JAX-B, for example Apache's CXF.
I have implemented a small class with the help of which you can handle long clicks on TextView itself and Taps on the links in the TextView.

If what you are looking to do is recover after failure, you could just build up a file that has what you've done so far.
if [[ -f $tmpf ]] ; then
rm -f $tmpf
fi
cat $srcf |
while read line ; do
# process line
echo "$line" >> $tmpf
done
They might be just a \r
or a \n
. I just checked and the text visualizer in VS 2010 displays both as newlines as well as \r\n
.
This string
string test = "blah\r\nblah\rblah\nblah";
Shows up as
blah
blah
blah
blah
in the text visualizer.
So you could try
string modifiedString = originalString
.Replace(Environment.NewLine, "<br />")
.Replace("\r", "<br />")
.Replace("\n", "<br />");
Try the 'requests' module, it's much simpler.

Without a bit of information about what files are in your repository (pure source code, images, executables, ...), it's a bit hard to answer the question :)
Beside this, I'll consider that you're willing to default to LF as line endings in your working directory because you're willing to make sure that text files have LF line endings in your .git repository wether you work on Windows or Linux. Indeed better safe than sorry....
However, there's a better alternative: Benefit from LF line endings in your Linux workdir, CRLF line endings in your Windows workdir AND LF line endings in your repository.
As you're partially working on Linux and Windows, make sure core.eol
is set to native
and core.autocrlf
is set to true
.
Then, replace the content of your .gitattributes
file with the following
* text=auto
This will let Git handle the automagic line endings conversion for you, on commits and checkouts. Binary files won't be altered, files detected as being text files will see the line endings converted on the fly.
However, as you know the content of your repository, you may give Git a hand and help him detect text files from binary files.
Provided you work on a C based image processing project, replace the content of your .gitattributes
file with the following
* text=auto
*.txt text
*.c text
*.h text
*.jpg binary
This will make sure files which extension is c, h, or txt will be stored with LF line endings in your repo and will have native line endings in the working directory. Jpeg files won't be touched. All of the others will be benefit from the same automagic filtering as seen above.
In order to get a get a deeper understanding of the inner details of all this, I'd suggest you to dive into this very good post "Mind the end of your line" from Tim Clem, a Githubber.
As a real world example, you can also peek at this commit where those changes to a .gitattributes
file are demonstrated.
UPDATE to the answer considering the following comment
I actually don't want CRLF in my Windows directories, because my Linux environment is actually a VirtualBox sharing the Windows directory
Makes sense. Thanks for the clarification. In this specific context, the .gitattributes
file by itself won't be enough.
Run the following commands against your repository
$ git config core.eol lf
$ git config core.autocrlf input
As your repository is shared between your Linux and Windows environment, this will update the local config file for both environment. core.eol
will make sure text files bear LF line endings on checkouts. core.autocrlf
will ensure potential CRLF in text files (resulting from a copy/paste operation for instance) will be converted to LF in your repository.
Optionally, you can help Git distinguish what is a text file by creating a .gitattributes
file containing something similar to the following:
# Autodetect text files
* text=auto
# ...Unless the name matches the following
# overriding patterns
# Definitively text files
*.txt text
*.c text
*.h text
# Ensure those won't be messed up with
*.jpg binary
*.data binary
If you decided to create a .gitattributes
file, commit it.
Lastly, ensure git status
mentions "nothing to commit (working directory clean)", then perform the following operation
$ git checkout-index --force --all
This will recreate your files in your working directory, taking into account your config changes and the .gitattributes
file and replacing any potential overlooked CRLF in your text files.
Once this is done, every text file in your working directory WILL bear LF line endings and git status
should still consider the workdir as clean.
You can straight use a DB to do it as an alternative. I use a DB function to do it that I call chk_lgn.
Check login checks to see if they are logged in or not and, in doing so, it sets the date time stamp of the check as last active in the user's db row/column.
I also do the time check there. This works for me for the moment as I use this function for every page.
P.S. No one I had seen had suggested a pure DB solution.
It means, the Class reference type can hold any Class object which represents any type. If JVM loads a type, a class object representing that type will be present in JVM. we can get the metadata regarding the type from that class object which is used very much in reflection package.
Suppose you have a a class named "myPackage.MyClass". Assuming that is in classpath, the following statements are equivalent.
Class<?> myClassObject = MyClass.class; //compile time check
Class<?> myClassObject = Class.forname("myPackage.MyClass"); //only runtime check
This works in a similar fashion if the Class<?> reference is in method argument as well.
Please note that the class "Class" does not have a public constructor. So you cannot instantiate "Class" instances with "new" operator.
use an enum type to indicate your ViewModel's State
public enum ViewModeType
{
Default,
Busy
//etc.
}
then in your ViewModels Base class use a property
public ViewModeType ViewMode
{
get { return this.viewMode; }
set
{
if (this.viewMode != value)
{
this.viewMode = value;
//You should notify property changed here
}
}
}
and in view trigger the ViewMode and if it is busy show busyindicator:
<Trigger Property="ViewMode" Value="Busy">
<!-- Show BusyIndicator -->
</Trigger>
Recently I found very easy and interesting function to print legend outside of the plot area where you want.
Make the outer margin at the right side of the plot.
par(xpd=T, mar=par()$mar+c(0,0,0,5))
Create a plot
plot(1:3, rnorm(3), pch = 1, lty = 1, type = "o", ylim=c(-2,2))
lines(1:3, rnorm(3), pch = 2, lty = 2, type="o")
Add legend and just use locator(1) function as like below. Then you have to just click where you want after load following script.
legend(locator(1),c("group A", "group B"), pch = c(1,2), lty = c(1,2))
Try it
You can also do this in phpMyAdmin without writing SQL.
Note: You'll see that phpMyAdmin is issuing the same SQL that is mentioned in the other answers.
Install distribute, which comes with egg_info

Use split
and map
function:
var str = "123, 124, 234,252";
var arr = str.split(",");
arr = arr.map(function (val) { return +val + 1; });
Notice +val
- string is casted to a number.
Or shorter:
var str = "123, 124, 234,252";
var arr = str.split(",").map(function (val) { return +val + 1; });
Today I'd advise against using +
operator to cast variable to a number. Instead I'd go with a more explicit but also more readable Number
call:
var str = "123, 124, 234,252";_x000D_
var arr = str.split(",").map(function (val) {_x000D_
return Number(val) + 1;_x000D_
});_x000D_
console.log(arr);
_x000D_
ECMAScript 2015 introduced arrow function so it could be used instead to make the code more concise:
var str = "123, 124, 234,252";_x000D_
var arr = str.split(",").map(val => Number(val) + 1);_x000D_
console.log(arr);
_x000D_
To change DatePicker
colors (calendar mode) at application level define below properties.
<style name="MyAppTheme" parent="Theme.AppCompat.Light">
<item name="colorAccent">#ff6d00</item>
<item name="colorControlActivated">#33691e</item>
<item name="android:selectableItemBackgroundBorderless">@color/colorPrimaryDark</item>
<item name="colorControlHighlight">#d50000</item>
</style>
See http://www.zoftino.com/android-datepicker-example for other DatePicker
custom styles
One of the Related posts gave me the (simple) answer.
Apparently the auto
value on the grid-template-rows
property does exactly what I was looking for.
.grid {
display:grid;
grid-template-columns: 1fr 1.5fr 1fr;
grid-template-rows: auto auto 1fr 1fr 1fr auto auto;
grid-gap:10px;
height: calc(100vh - 10px);
}
Instead a format such as yours, use ISO 8601 standard formats for exchanging date-time values as text.
The java.time classes use the standard ISO 8601 formats by default when parsing/generating strings.
Specify a proper time zone name in the format of continent/region
, such as America/Montreal
, Africa/Casablanca
, or Pacific/Auckland
. Never use the 3-4 letter abbreviation such as EST
or IST
as they are not true time zones, not standardized, and not even unique(!).
Your IST
could mean Iceland Standard Time, India Standard Time, Ireland Standard Time, or others. The java.time classes are left to merely guessing, as there is no logical solution to this ambiguity.
The modern approach uses the java.time classes.
Define a formatting pattern to match your input strings.
String input = "Sat Jun 01 12:53:10 IST 2013";
DateTimeFormatter f = DateTimeFormatter.ofPattern( "EEE MMM dd HH:mm:ss z uuuu" , Locale.US );
ZonedDateTime zdt = ZonedDateTime.parse( input , f );
zdt.toString(): 2013-06-01T12:53:10Z[Atlantic/Reykjavik]
If your input was not intended for Iceland, you should pre-parse the string to adjust to a proper time zone name. For example, if you are certain the input was intended for India, change IST
to Asia/Kolkata
.
String input = "Sat Jun 01 12:53:10 IST 2013".replace( "IST" , "Asia/Kolkata" );
DateTimeFormatter f = DateTimeFormatter.ofPattern( "EEE MMM dd HH:mm:ss z uuuu" , Locale.US );
ZonedDateTime zdt = ZonedDateTime.parse( input , f );
zdt.toString(): 2013-06-01T12:53:10+05:30[Asia/Kolkata]
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date
, Calendar
, & SimpleDateFormat
.
The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.
You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.*
classes.
Where to obtain the java.time classes?
The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval
, YearWeek
, YearQuarter
, and more.
Here goes.. Cheers!

Steven Levithan once wrote about how to implement a Faster JavaScript Trim. It’s definitely worth a look.
I use this one:
select max(table_catalog) as x from information_schema.tables
to check connection and ability to run queries (with 1 row as result) for postgreSQL, MySQL and MSSQL.
You can use a FileOutputStream for this.
FileOutputStream fos = null;
try {
fos = new FileOutputStream(new File("myFile"));
ByteArrayOutputStream baos = new ByteArrayOutputStream();
// Put data in your baos
baos.writeTo(fos);
} catch(IOException ioe) {
// Handle exception here
ioe.printStackTrace();
} finally {
fos.close();
}
typeof document.location; // 'object'
typeof document.location.href; // 'string'
The href
property is a string, while document.location
itself is an object.
In C# 8.0 and above, you can use the range operator ..
as in
var s = "header-THE_TARGET_STRING.7z";
var from = s.IndexOf("-") + "-".Length;
var to = s.IndexOf(".7z");
var versionString = s[from..to]; // THE_TARGET_STRING
See documentation for details.
I would put this as a comment, but I don't have the rep for it. What Josh Crozier answered is correct, but for IE .cur and .ani are the only supported formats for this. So you should probably have a fallback just in case:
.test {
cursor:url("http://www.javascriptkit.com/dhtmltutors/cursor-hand.gif"), url(foo.cur), auto;
}
