Not that simple:
python -c "import os; os.putenv('MY_DATA','1233')"
$ echo $MY_DATA # <- empty
But:
python -c "import os; os.putenv('MY_DATA','123'); os.system('bash')"
$ echo $MY_DATA #<- 123
Interfaces allow statically typed languages to support polymorphism. An Object Oriented purist would insist that a language should provide inheritance, encapsulation, modularity and polymorphism in order to be a fully-featured Object Oriented language. In dynamically-typed - or duck typed - languages (like Smalltalk,) polymorphism is trivial; however, in statically typed languages (like Java or C#,) polymorphism is far from trivial (in fact, on the surface it seems to be at odds with the notion of strong typing.)
Let me demonstrate:
In a dynamically-typed (or duck typed) language (like Smalltalk), all variables are references to objects (nothing less and nothing more.) So, in Smalltalk, I can do this:
|anAnimal|
anAnimal := Pig new.
anAnimal makeNoise.
anAnimal := Cow new.
anAnimal makeNoise.
That code:
makeNoise
to the pig.The same Java code would look something like this (making the assumption that Duck and Cow are subclasses of Animal:
Animal anAnimal = new Pig();
duck.makeNoise();
anAnimal = new Cow();
cow.makeNoise();
That's all well and good, until we introduce class Vegetable. Vegetables have some of the same behavior as Animal, but not all. For example, both Animal and Vegetable might be able to grow, but clearly vegetables don't make noise and animals cannot be harvested.
In Smalltalk, we can write this:
|aFarmObject|
aFarmObject := Cow new.
aFarmObject grow.
aFarmObject makeNoise.
aFarmObject := Corn new.
aFarmObject grow.
aFarmObject harvest.
This works perfectly well in Smalltalk because it is duck-typed (if it walks like a duck, and quacks like a duck - it is a duck.) In this case, when a message is sent to an object, a lookup is performed on the receiver's method list, and if a matching method is found, it is called. If not, some kind of NoSuchMethodError exception is thrown - but it's all done at runtime.
But in Java, a statically typed language, what type can we assign to our variable? Corn needs to inherit from Vegetable, to support grow, but cannot inherit from Animal, because it does not make noise. Cow needs to inherit from Animal to support makeNoise, but cannot inherit from Vegetable because it should not implement harvest. It looks like we need multiple inheritance - the ability to inherit from more than one class. But that turns out to be a pretty difficult language feature because of all the edge cases that pop up (what happens when more than one parallel superclass implement the same method?, etc.)
Along come interfaces...
If we make Animal and Vegetable classes, with each implementing Growable, we can declare that our Cow is Animal and our Corn is Vegetable. We can also declare that both Animal and Vegetable are Growable. That lets us write this to grow everything:
List<Growable> list = new ArrayList<Growable>();
list.add(new Cow());
list.add(new Corn());
list.add(new Pig());
for(Growable g : list) {
g.grow();
}
And it lets us do this, to make animal noises:
List<Animal> list = new ArrayList<Animal>();
list.add(new Cow());
list.add(new Pig());
for(Animal a : list) {
a.makeNoise();
}
The advantage to the duck-typed language is that you get really nice polymorphism: all a class has to do to provide behavior is provide the method. As long as everyone plays nice, and only sends messages that match defined methods, all is good. The downside is that the kind of error below isn't caught until runtime:
|aFarmObject|
aFarmObject := Corn new.
aFarmObject makeNoise. // No compiler error - not checked until runtime.
Statically-typed languages provide much better "programming by contract," because they will catch the two kinds of error below at compile-time:
// Compiler error: Corn cannot be cast to Animal.
Animal farmObject = new Corn();
farmObject makeNoise();
--
// Compiler error: Animal doesn't have the harvest message.
Animal farmObject = new Cow();
farmObject.harvest();
So....to summarize:
Interface implementation allows you to specify what kinds of things objects can do (interaction) and Class inheritance lets you specify how things should be done (implementation).
Interfaces give us many of the benefits of "true" polymorphism, without sacrificing compiler type checking.
As the accepted answer requires you to add a Frame Layout, here how you can do it with material design.
Add this if you haven't already
implementation 'com.google.android.material:material:1.0.0'
Now change to Cardview to MaterialCardView
<com.google.android.material.card.MaterialCardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="16dp"
app:cardCornerRadius="8dp"
app:cardElevation="2dp"
app:strokeWidth="1dp"
app:strokeColor="@color/black">
Now you need to change the activity theme to Theme.Material. If you are using Theme.Appcompact I will suggest you to move to Theme.Material for future projects for having better material design in you app.
<style name="AppTheme" parent="Theme.MaterialComponents.DayNight">
I got the same error with vlc component when i changed the framework from 4.5 to 4. but it worked for me when I changed the platform from Any CPU to x86.
you can use the below code to bring focus to a div, in this example the page scrolls to the <div id="navigation">
$('html, body').animate({ scrollTop: $('#navigation').offset().top }, 'slow');
It's perfectly normal in Javascript (and many languages) to have functions inside functions.
Take the time to learn the language, don't use it on the basis that it's similar to what you already know. I'd suggest watching Douglas Crockford's series of YUI presentations on Javascript, with special focus on Act III: Function the Ultimate (link to video download, slides, and transcript)
You can use eclipse to generate a runnable Jar : Export/Runable Jar file
This one is noteworthy as well
<div ng-repeat="post in posts" ng-if="post.type=='article'">
<h1>{{post.title}}</h1>
</div>
Undoubtedly, for your purposes (which I assume is just a programming exercise), the best thing is to check your results against any of the listings of the digits of pi on the web.
And how do we know that those values are correct? Well, I could say that there are computer-science-y ways to prove that an implementation of an algorithm is correct.
More pragmatically, if different people use different algorithms, and they all agree to (pick a number) a thousand (million, whatever) decimal places, that should give you a warm fuzzy feeling that they got it right.
Historically, William Shanks published pi to 707 decimal places in 1873. Poor guy, he made a mistake starting at the 528th decimal place.
Very interestingly, in 1995 an algorithm was published that had the property that would directly calculate the nth digit (base 16) of pi without having to calculate all the previous digits!
Finally, I hope your initial algorithm wasn't pi/4 = 1 - 1/3 + 1/5 - 1/7 + ...
That may be the simplest to program, but it's also one of the slowest ways to do so. Check out the pi article on Wikipedia for faster approaches.
Ok. I found the solution here tessnet2 fails to load the Ans given by Adam
Apparently i was using wrong version of tessdata. I was following the the source page instruction intuitively and that caused the problem.
it says
Quick Tessnet2 usage
Download binary here, add a reference of the assembly Tessnet2.dll to your .NET project.
Download language data definition file here and put it in tessdata directory. Tessdata directory and your exe must be in the same directory.
After you download the binary, when you follow the link to download the language file, there are many language files. but none of them are right version. you need to select all version and go to next page for correct version (tesseract-2.00.eng)! They should either update download binary link to version 3 or put the the version 2 language file on the first page. Or at least bold mention the fact that this version issue is a big deal!
Anyway I found it. Thanks everyone.
Looks like this is unimplemented, as of the time of this writing:

For libsass (C/C++ implementation), import works for *.css
the same way as for *.scss
files - just omit the extension:
@import "path/to/file";
This will import path/to/file.css
.

Cellspacing is all around the cell and cannot be changed (i.e. if it's set to one, there will be 1 pixel of space on all sides). Padding can be specified discreetly (e.g. padding-top
, padding-bottom
, padding-left
, and padding-right;
or padding: [top] [right] [bottom] [left];
).
I implemented some code to do it manually:
using System.Security.Principal;
public bool IsUserAdministrator()
{
bool isAdmin;
try
{
WindowsIdentity user = WindowsIdentity.GetCurrent();
WindowsPrincipal principal = new WindowsPrincipal(user);
isAdmin = principal.IsInRole(WindowsBuiltInRole.Administrator);
}
catch (UnauthorizedAccessException ex)
{
isAdmin = false;
}
catch (Exception ex)
{
isAdmin = false;
}
return isAdmin;
}
This code is ill-formed:
int&const icr=i;
Reference: C++17 [dcl.ref]/1:
Cv-qualified references are ill-formed except when the cv-qualifiers are introduced through the use of a typedef-name or decltype-specifier, in which case the cv-qualifiers are ignored.
This rule has been present in all standardized versions of C++. Because the code is ill-formed:
The compiler should reject the program; and if it doesn't, the executable's behaviour is completely undefined.
NB: Not sure how none of the other answers mentioned this yet... nobody's got access to a compiler?

Every object has a toString() method in Java.
You should try and avoid jQuery in ReactJS. But if you really want to use it, you'd put it in componentDidMount() lifecycle function of the component.
e.g.
class App extends React.Component {
componentDidMount() {
// Jquery here $(...)...
}
// ...
}
Ideally, you'd want to create a reusable Accordion component. For this you could use Jquery, or just use plain javascript + CSS.
class Accordion extends React.Component {
constructor() {
super();
this._handleClick = this._handleClick.bind(this);
}
componentDidMount() {
this._handleClick();
}
_handleClick() {
const acc = this._acc.children;
for (let i = 0; i < acc.length; i++) {
let a = acc[i];
a.onclick = () => a.classList.toggle("active");
}
}
render() {
return (
<div
ref={a => this._acc = a}
onClick={this._handleClick}>
{this.props.children}
</div>
)
}
}
Then you can use it in any component like so:
class App extends React.Component {
render() {
return (
<div>
<Accordion>
<div className="accor">
<div className="head">Head 1</div>
<div className="body"></div>
</div>
</Accordion>
</div>
);
}
}

In the action you can call:
this.Request.PhysicalPath
that returns the physical path in reference to the current controller. If you only need the root path call:
this.Request.PhysicalApplicationPath
here is how to fix it:

Variables->New: Variable name: _JAVA_OPTIONS
Variable value: -Xmx512M
Variable name: Path
Variable value: %PATH%;C:\Program Files\Java\jre6\bin;F:\JDK\bin;
Change this to your appropriate path.
Use Str()
Function. It takes three arguments(the number, the number total characters to display, and the number of decimal places to display
Select Str(12345.6789, 12, 3)
displays: ' 12345.679' ( 3 spaces, 5 digits 12345, a decimal point, and three decimal digits (679). - it rounds if it has to truncate, (unless the integer part is too large for the total size, in which case asterisks are displayed instead.)
for a Total of 12 characters, with 3 to the right of decimal point.
Reading app/config/mailphp
Supported : "smtp", "mail", "sendmail"
Depending on your mail utilities installed on your machine, fill in the value of the driver key. I would do
'driver' => 'sendmail',
Is required that you have a form?
If not, then you could use this:
<div>
<input type="hidden" value="ServletParameter" />
<input type="button" id="callJavaScriptServlet" onclick="callJavaScriptServlet()" />
</div>
with the following JavaScript:
function callJavaScriptServlet() {
this.form.action = "MyServlet";
this.form.submit();
}

I found a much simpler alternative way to generating soap message. Given a Person Object:
import com.fasterxml.jackson.annotation.JsonInclude;
@JsonInclude(JsonInclude.Include.NON_NULL)
public class Person {
private String name;
private int age;
private String address; //setter and getters below
}
Below is a simple Soap Message Generator:
import com.fasterxml.jackson.databind.DeserializationFeature;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import com.fasterxml.jackson.datatype.jsr310.JavaTimeModule;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang3.StringUtils;
import com.fasterxml.jackson.dataformat.xml.XmlMapper;
@Slf4j
public class SoapGenerator {
protected static final ObjectMapper XML_MAPPER = new XmlMapper()
.enable(DeserializationFeature.READ_UNKNOWN_ENUM_VALUES_AS_NULL)
.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false)
.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false)
.registerModule(new JavaTimeModule());
private static final String SOAP_BODY_OPEN = "<soap:Body>";
private static final String SOAP_BODY_CLOSE = "</soap:Body>";
private static final String SOAP_ENVELOPE_OPEN = "<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">";
private static final String SOAP_ENVELOPE_CLOSE = "</soap:Envelope>";
public static String soapWrap(String xml) {
return SOAP_ENVELOPE_OPEN + SOAP_BODY_OPEN + xml + SOAP_BODY_CLOSE + SOAP_ENVELOPE_CLOSE;
}
public static String soapUnwrap(String xml) {
return StringUtils.substringBetween(xml, SOAP_BODY_OPEN, SOAP_BODY_CLOSE);
}
}
You can use by:
public static void main(String[] args) throws Exception{
Person p = new Person();
p.setName("Test");
p.setAge(12);
String xml = SoapGenerator.soapWrap(XML_MAPPER.writeValueAsString(p));
log.info("Generated String");
log.info(xml);
}
Create a custom Router
with its own browserHistory
:
import React from 'react';
import { Router } from 'react-router-dom';
import { createBrowserHistory } from 'history';
export const history = createBrowserHistory();
const ExtBrowserRouter = ({children}) => (
<Router history={history} >
{ children }
</Router>
);
export default ExtBrowserRouter
Next, on your Root where you define your Router
, use the following:
import React from 'react';
import { /*BrowserRouter,*/ Route, Switch, Redirect } from 'react-router-dom';
//Use 'ExtBrowserRouter' instead of 'BrowserRouter'
import ExtBrowserRouter from './ExtBrowserRouter';
...
export default class Root extends React.Component {
render() {
return (
<Provider store={store}>
<ExtBrowserRouter>
<Switch>
...
<Route path="/login" component={Login} />
...
</Switch>
</ExtBrowserRouter>
</Provider>
)
}
}
Finally, import history
where you need it and use it:
import { history } from '../routers/ExtBrowserRouter';
...
export function logout(){
clearTokens();
history.push('/login'); //WORKS AS EXPECTED!
return Promise.reject('Refresh token has expired');
}
Escape your HTML tags ...

There are two different contexts in Android. One for your application (Let's call it the BIG one) and one for each view (let's call it the activity context).
A linearLayout is a view, so you have to call the activity context. To call it from an activity, simply call "this". So easy isn't it?
When you use
this.getApplicationContext();
You call the BIG context, the one that describes your application and cannot manage your view.
A big problem with Android is that a context cannot call your activity. That's a big deal to avoid this when someone begins with the Android development. You have to find a better way to code your class (or replace "Context context" by "Activity activity" and cast it to "Context" when needed).
Regards.
Just to update my answer. The easiest way to get your Activity context
is to define a static
instance in your Activity
. For example
public class DummyActivity extends Activity
{
public static DummyActivity instance = null;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
// Do some operations here
}
@Override
public void onResume()
{
super.onResume();
instance = this;
}
@Override
public void onPause()
{
super.onPause();
instance = null;
}
}
And then, in your Task
, Dialog
, View
, you could use that kind of code to get your Activity context
:
if (DummyActivity.instance != null)
{
// Do your operations with DummyActivity.instance
}
I had the same problem, and I resolve doing this npm update
. But I receive the message about permission, so I run:
sudo chwon -R myuser /home/myUserFolder/.config
This set permissions for my user run npm comands like administrator. Then I run this again:
npm update
and this:
npm install gulp-sass
Then my problem with this was solved.
Same issue with mine.
New to Flutter. I'm using VS build-in terminal to do flutter run
, to run the app in iPhone. It gives me error Error when reading 'lib/student_model.dart': No such file...
, which is an old code version in my code. I have changed it to lib/model/student_model.dart
.
And I search this line 'lib/student_model.dart'in the project, it appears file
kernel_snapshot.d` containing it. So, it build the project with old code version.
For me, Flutter clean
is not working. Restart VS fix the issue, not sure the problem is due to Flutter or VS?
And I'm wondering if there is some command to just build flutter project without run?
using jQuery:
$(function() {
function unifyHeights() {
var maxHeight = 0;
$('#container').children('#navigation, #content').each(function() {
var height = $(this).outerHeight();
// alert(height);
if ( height > maxHeight ) {
maxHeight = height;
}
});
$('#navigation, #content').css('height', maxHeight);
}
unifyHeights();
});
You need to do two things:
ie
one.start();
one.join();
If you don't start()
it, nothing will happen - creating a Thread doesn't execute it.
If you don't join)
it, your main thread may finish and exit and the whole program exit before the other thread has been scheduled to execute. It's indeterminate whether it runs or not if you don't join it. The new thread may usually run, but may sometimes not run. Better to be certain.
left:auto;
This will default the left
back to the browser default.
So if you have your Markup/CSS as:
<div class="myClass"></div>
.myClass
{
position:absolute;
left:0;
}
When setting RTL, you could change to:
<div class="myClass rtl"></div>
.myClass
{
position:absolute;
left:0;
}
.myClass.rtl
{
left:auto;
right:0;
}
If you don't want to install extra packages, ctypes
can get the job done as well.
import ctypes

kernel32.GlobalUnlock.argtypes = [ctypes.c_void_p]
user32 = ctypes.windll.user32
user32.GetClipboardData.restype = ctypes.c_void_p
def get_clipboard_text():
user32.OpenClipboard(0)
try:
if user32.IsClipboardFormatAvailable(CF_TEXT):
data = user32.GetClipboardData(CF_TEXT)
data_locked = kernel32.GlobalLock(data)
text = ctypes.c_char_p(data_locked)
value = text.value
kernel32.GlobalUnlock(data_locked)

finally:
user32.CloseClipboard()
print(get_clipboard_text())
public class LmsEmpWfhUtils {

This prevents the default parameter-less constructor from being used elsewhere in your code.

I feel some PNG files are corrupted and were not parsed. Sometimes the images have an extension but are not real PNG.
You can check if the images in your project are real PNGs with the below command :
find . -type f -name "*.png" | xargs -L 1 -I{} file -I {} | grep -v 'image/png; charset=binary$'
After getting the list use this site to convert them to PNG. Then check your build again.

This is a standard interview question:
Is memory allocated at runtime using calloc()
, malloc()
and friends. It is sometimes also referred to as 'heap' memory, although it has nothing to do with the heap data-structure ref.
int * a = malloc(sizeof(int));
Heap memory is persistent until free()
is called. In other words, you control the lifetime of the variable.
This is what is commonly known as 'stack' memory, and is allocated when you enter a new scope (usually when a new function is pushed on the call stack). Once you move out of the scope, the values of automatic memory addresses are undefined, and it is an error to access them.
int a = 43;
Note that scope does not necessarily mean function. Scopes can nest within a function, and the variable will be in-scope only within the block in which it was declared. Note also that where this memory is allocated is not specified. (On a sane system it will be on the stack, or registers for optimisation)
Is allocated at compile time*, and the lifetime of a variable in static memory is the lifetime of the program.
In C, static memory can be allocated using the static
keyword. The scope is the compilation unit only.
Things get more interesting when the extern
keyword is considered. When an extern
variable is defined the compiler allocates memory for it. When an extern
variable is declared, the compiler requires that the variable be defined elsewhere. Failure to declare/define extern
variables will cause linking problems, while failure to declare/define static
variables will cause compilation problems.
in file scope, the static keyword is optional (outside of a function):
int a = 32;
But not in function scope (inside of a function):
static int a = 32;
Technically, extern
and static
are two separate classes of variables in C.
extern int a; /* Declaration */
int a; /* Definition */
It's somewhat confusing to say that static memory is allocated at compile time, especially if we start considering that the compilation machine and the host machine might not be the same or might not even be on the same architecture.
It may be better to think that the allocation of static memory is handled by the compiler rather than allocated at compile time.
For example the compiler may create a large data
section in the compiled binary and when the program is loaded in memory, the address within the data
segment of the program will be used as the location of the allocated memory. This has the marked disadvantage of making the compiled binary very large if uses a lot of static memory. It's possible to write a multi-gigabytes binary generated from less than half a dozen lines of code. Another option is for the compiler to inject initialisation code that will allocate memory in some other way before the program is executed. This code will vary according to the target platform and OS. In practice, modern compilers use heuristics to decide which of these options to use. You can try this out yourself by writing a small C program that allocates a large static array of either 10k, 1m, 10m, 100m, 1G or 10G items. For many compilers, the binary size will keep growing linearly with the size of the array, and past a certain point, it will shrink again as the compiler uses another allocation strategy.
The last memory class are 'register' variables. As expected, register variables should be allocated on a CPU's register, but the decision is actually left to the compiler. You may not turn a register variable into a reference by using address-of.
register int meaning = 42;
printf("%p\n",&meaning); /* this is wrong and will fail at compile time. */
Most modern compilers are smarter than you at picking which variables should be put in registers :)
The field nbytes will give you the size in bytes of all the elements of the array in a numpy.array
:
size_in_bytes = my_numpy_array.nbytes
Notice that this does not measures "non-element attributes of the array object" so the actual size in bytes can be a few bytes larger than this.
To read a binary file to a bytes
object:
from pathlib import Path
data = Path('/path/to/file').read_bytes() # Python 3.5+
To create an int
from bytes 0-3 of the data:
i = int.from_bytes(data[:4], byteorder='little', signed=False)
To unpack multiple int
s from the data:
import struct
ints = struct.unpack('iiii', data[:16])
Using the @Override
annotation acts as a compile-time safeguard against a common programming mistake. It will throw a compilation error if you have the annotation on a method you're not actually overriding the superclass method.
The most common case where this is useful is when you are changing a method in the base class to have a different parameter list. A method in a subclass that used to override the superclass method will no longer do so due the changed method signature. This can sometimes cause strange and unexpected behavior, especially when dealing with complex inheritance structures. The @Override
annotation safeguards against this.
Have you thought about not using a factory at all, and instead making nice use of the type system? I can think of two different approaches which do this sort of thing:
Option 1:
struct linear {
linear(float x, float y) : x_(x), y_(y){}
float x_;
float y_;
};
struct polar {
polar(float angle, float magnitude) : angle_(angle), magnitude_(magnitude) {}
float angle_;
float magnitude_;
};
struct Vec2 {
explicit Vec2(const linear &l) { /* ... */ }
explicit Vec2(const polar &p) { /* ... */ }
};
Which lets you write things like:
Vec2 v(linear(1.0, 2.0));
Option 2:
you can use "tags" like the STL does with iterators and such. For example:
struct linear_coord_tag linear_coord {}; // declare type and a global
struct polar_coord_tag polar_coord {};
struct Vec2 {
Vec2(float x, float y, const linear_coord_tag &) { /* ... */ }
Vec2(float angle, float magnitude, const polar_coord_tag &) { /* ... */ }
};
This second approach lets you write code which looks like this:
Vec2 v(1.0, 2.0, linear_coord);
which is also nice and expressive while allowing you to have unique prototypes for each constructor.
Since Version 0.7.7 there is a new way to create an aggregated report:
You create a separate 'report' project which collects all the necessary reports (Any goal in the aggregator project is executed before its modules therefore it can't be used).
aggregator pom
|- parent pom
|- module a
|- module b
|- report module
The root pom looks like this (don't forget to add the new report module under modules):
<build>
<plugins>
<plugin>
<groupId>org.jacoco</groupId>

A full exmple can be found here.
If you try to decrypt PKCS5-padded data with the wrong key, and then unpad it (which is done by the Cipher class automatically), you most likely will get the BadPaddingException (with probably of slightly less than 255/256, around 99.61%), because the padding has a special structure which is validated during unpad and very few keys would produce a valid padding.
So, if you get this exception, catch it and treat it as "wrong key".
This also can happen when you provide a wrong password, which then is used to get the key from a keystore, or which is converted into a key using a key generation function.
Of course, bad padding can also happen if your data is corrupted in transport.
That said, there are some security remarks about your scheme:
For password-based encryption, you should use a SecretKeyFactory and PBEKeySpec instead of using a SecureRandom with KeyGenerator. The reason is that the SecureRandom could be a different algorithm on each Java implementation, giving you a different key. The SecretKeyFactory does the key derivation in a defined manner (and a manner which is deemed secure, if you select the right algorithm).
Don't use ECB-mode. It encrypts each block independently, which means that identical plain text blocks also give always identical ciphertext blocks.
Preferably use a secure mode of operation, like CBC (Cipher block chaining) or CTR (Counter). Alternatively, use a mode which also includes authentication, like GCM (Galois-Counter mode) or CCM (Counter with CBC-MAC), see next point.
You normally don't want only confidentiality, but also authentication, which makes sure the message is not tampered with. (This also prevents chosen-ciphertext attacks on your cipher, i.e. helps for confidentiality.) So, add a MAC (message authentication code) to your message, or use a cipher mode which includes authentication (see previous point).
DES has an effective key size of only 56 bits. This key space is quite small, it can be brute-forced in some hours by a dedicated attacker. If you generate your key by a password, this will get even faster. Also, DES has a block size of only 64 bits, which adds some more weaknesses in chaining modes. Use a modern algorithm like AES instead, which has a block size of 128 bits, and a key size of 128 bits (for the standard variant).
I have also encountered this error for a Web API (.Net Core 3.0) action that was binding to a string
instead to an object
or a JObject
. The JSON was correct, but the binder tried to get a string from the JSON structure and failed.
So, instead of:
[HttpPost("[action]")]
public object Search([FromBody] string data)
I had to use the more specific:
[HttpPost("[action]")]
public object Search([FromBody] JObject data)
Here is my approach:
>>> import os
>>> print os.path.basename(
os.path.dirname('/folderA/folderB/folderC/folderD/test.py'))
folderD
>>> print os.path.basename(
os.path.dirname('/folderA/folderB/folderC/folderD/'))
folderD
>>> print os.path.basename(
os.path.dirname('/folderA/folderB/folderC/folderD'))
folderC
Your categorization is not correct:
php, asp and ColdFusion are mostly used for websites, that is correct, but .net is definetly much more than asp you can build desktop applications, too (Paint.NET). I don't know about ColdFusion, but PHP can also be used to write desktop applications.
On the other hand C,C++ are not really often used for web programming, But it can be used for web programming (cgit). Java is definetly a language to develop web applications (spring and much more).
Python is a scripting language like PHP, Perl, Ruby and so much more. It can be used for web programming (django, Zope, Google App Engine, and much more). But it also can be used for desktop applications (Blender 3D, or even for games pygame).
Python can also be translated into binary code like java.
The ISO is probably pre-pidded. You'll need to delete the key from the setup files. It should then ask you for a key during installation.
I found this example and incorporated it into a function:
public static int solution1(int A, int B)
{
// Check if A and B are in [0...999,999,999]
if ( (A >= 0 && A <= 999999999) && (B >= 0 && B <= 999999999))
{
if (A == 0 && B == 0)
{
return 0;
}
// Make sure A < B
if (A < B)
{
// Convert A and B to strings
string a = A.ToString();
string b = B.ToString();
int index = 0;
// See if A is a substring of B
if (b.Contains(a))
{
// Find index where A is
if (b.IndexOf(a) != -1)
{
while ((index = b.IndexOf(a, index)) != -1)
{
Console.WriteLine(A + " found at position " + index);
index++;
}
Console.ReadLine();
return b.IndexOf(a);
}
else
return -1;
}
else
{
Console.WriteLine(A + " is not in " + B + ".");
Console.ReadLine();
return -1;
}
}
else
{
Console.WriteLine(A + " must be less than " + B + ".");
// Console.ReadLine();
return -1;
}
}
else
{
Console.WriteLine("A or B is out of range.");
//Console.ReadLine();
return -1;
}
}
static void Main(string[] args)
{
int A = 53, B = 1953786;
int C = 78, D = 195378678;
int E = 57, F = 153786;
solution1(A, B);
solution1(C, D);
solution1(E, F);
Console.WriteLine();
}
Returns:
53 found at position 2
78 found at position 4
78 found at position 7
57 is not in 153786
IN completion to above answers, you can also customize your fallbacks for each async call you do, so that each call to the generic ASYNC method will populate different data, depending on the onTaskDone stuff you put there.
Main.FragmentCallback FC= new Main.FragmentCallback(){
@Override
public void onTaskDone(String results) {
localText.setText(results); //example TextView
}
};
new API_CALL(this.getApplicationContext(), "GET",FC).execute("&Books=" + Main.Books + "&args=" + profile_id);
Remind: I used interface on the main activity thats where "Main" comes, like this:
public interface FragmentCallback {
public void onTaskDone(String results);
}
My API post execute looks like this:
@Override
protected void onPostExecute(String results) {
Log.i("TASK Result", results);
mFragmentCallback.onTaskDone(results);
}
The API constructor looks like this:
class API_CALL extends AsyncTask<String,Void,String> {
private Main.FragmentCallback mFragmentCallback;
private Context act;
private String method;
public API_CALL(Context ctx, String api_method,Main.FragmentCallback fragmentCallback) {
act=ctx;
method=api_method;
mFragmentCallback = fragmentCallback;
}
melt()
from the reshape2 package gets you close ...
library(reshape2)
(res <- melt(as.data.frame(mat), id="time"))
# time variable value
# 1 0.0 C_0 0.1
# 2 0.5 C_0 0.2
# 3 1.0 C_0 0.3
# 4 0.0 C_1 0.3
# 5 0.5 C_1 0.4
# 6 1.0 C_1 0.5
... although you may want to post-process its results to get your preferred column names and ordering.
setNames(res[c("variable", "time", "value")], c("name", "time", "val"))
# name time val
# 1 C_0 0.0 0.1
# 2 C_0 0.5 0.2
# 3 C_0 1.0 0.3
# 4 C_1 0.0 0.3
# 5 C_1 0.5 0.4
# 6 C_1 1.0 0.5
An answer to a slightly different question: You can use vh
units to pad elements to the center of the viewport:
.centerme {
margin-top: 50vh;
background: red;
}
<div class="centerme">middle</div>
For an out-of-the-box working example, this is what I ended up using based on the previous answers.
using System.Reflection;
using System.Runtime.InteropServices;
label1.Text = "GUID: " + ((GuidAttribute)Attribute.GetCustomAttribute(Assembly.GetExecutingAssembly(), typeof(GuidAttribute), false)).Value.ToUpper();
Alternatively, this way allows you to use it from a static class:
/// <summary>
/// public GUID property for use in static class </summary>
/// <returns>
/// Returns the application GUID or "" if unable to get it. </returns>
static public string AssemblyGuid
{
get
{
object[] attributes = Assembly.GetEntryAssembly().GetCustomAttributes(typeof(GuidAttribute), false);
if (attributes.Length == 0) { return String.Empty; }
return ((System.Runtime.InteropServices.GuidAttribute)attributes[0]).Value.ToUpper();
}
}
Pattern p = Pattern.compile("(([A-Z].*[0-9])");
Matcher m = p.matcher("TEST 123");
boolean b = m.find();
System.out.println(b);
You can use this:
SELECT CONVERT(VARCHAR(5), GETDATE(),8)
Output:
08:24
The most valuable thing it does is give you another string identical to the first, without requiring you to allocate memory (location and size) yourself. But, as noted, you still need to free it (but which doesn't require a quantity calculation, either.)
If you use Wordpress you can just use the wordpress build in function with the video id provided wp_get_attachment_metadata($videoID):
wp_get_attachment_metadata($videoID);
helped me a lot. thats why i'm posting it, although its just for wordpress users.
Append the sheet name to the formula which makes the reference absolute. For example, if the cell reference is =T7 make it =Sheet1!T7. Paste-link would have done the same thing except only when pasting to another sheet. Paste-link does not work as expected if you are pasting in to the same sheet.
If you want distinct values from only two fields, plus return other fields with them, then the other fields must have some kind of aggregation on them (sum, min, max, etc.), and the two columns you want distinct must appear in the group by clause. Otherwise, it's just as Decker says.
The way is correct, but can be improved a bit with the extended set-syntax.
set "var=xyz"
Sets the var to the content until the last quotation mark, this ensures that no "hidden" spaces are appended.
Your code would look like
set "var1=A"
set "var2=B"
set "AB=hi"
set "newvar=%var1%%var2%"
echo %newvar% is the concat of var1 and var2
echo !%newvar%! is the indirect content of newvar

Git is supposed to understand what files already exist on the server, unless you somehow made a huge difference to your tree and the new changes need to be sent.
To create a new branch with a copy of your current state
git checkout -b new_branch #< create a new local branch with a copy of your code
git push origin new_branch #< pushes to the server
Can you please describe the steps you did to understand what might have made your repository need to send that much to the server.
You are inside a namespace
so you should use \Exception
to specify the global namespace:
try {
$this->buildXMLHeader();
} catch (\Exception $e) {
return $e->getMessage();
}
In your code you've used catch (Exception $e)
so Exception
is being searched in/as:
App\Services\PayUService\Exception
Since there is no Exception
class inside App\Services\PayUService
so it's not being triggered. Alternatively, you can use a use
statement at the top of your class like use Exception;
and then you can use catch (Exception $e)
.
A better and modern approach is to use ES6 Fetch API to check if an image exists or not:
fetch('https://via.placeholder.com/150', { method: 'HEAD' })
.then(res => {
if (res.ok) {
console.log('Image exists.');
} else {
console.log('Image does not exist.');
}
}).catch(err => console.log('Error:', err));
Make sure you are either making the same-origin requests or CORS is enabled on the server.
Probably because you had something like this?
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
Uri fileUri = CommonUtilities.getTBCameraOutputMediaFileUri();
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
startActivityForResult(takePictureIntent, 2);
However you must not put the extra output into the intent, because then the data goes into the URI instead of the data variable. For that reason, you have to take the two lines in the middle out, so that you have
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(takePictureIntent, 2);
That´s what caused the problem for me, hope that helped.
Your primary question has been answered above. I just wanted to point out that the regex you're using has a bug. It will also succeed on foo-domain.com

- Building HibernateI had the same problem, but setting windowSoftInputMode
did not help, and I did not want to change the upper view to have isScrollContainer="false"

My solution was to define the top location of the navigation tools instead of the bottom. I'm using Titanium, so I'm not sure exactly how this would translate to android. Defining the top location of the navigation tools view prevented the soft keyboard from pushing it up, and instead covered the nav controls like I wanted.
for numerical solution, you can use fsolve:
http://docs.scipy.org/doc/scipy/reference/generated/scipy.optimize.fsolve.html#scipy.optimize.fsolve
from scipy.optimize import fsolve
import math
def equations(p):
x, y = p
return (x+y**2-4, math.exp(x) + x*y - 3)
x, y = fsolve(equations, (1, 1))
print equations((x, y))
This will remove empty lines or lines with only whitespace characters (tabs/spaces).

This is pretty easy using the JavaScript selenium-webdriver
client:
First, make sure you have a WebDriver server running. For example, download ChromeDriver, then run chromedriver --port=9515
.
Second, create the driver like this:
var driver = new webdriver.Builder()
.withCapabilities(webdriver.Capabilities.chrome())
.usingServer('http://localhost:9515') // <- this
.build();
Here's a complete example:
var webdriver = require('selenium-webdriver');
var driver = new webdriver.Builder()
.withCapabilities(webdriver.Capabilities.chrome())
.usingServer('http://localhost:9515')
.build();
driver.get('http://www.google.com');
driver.findElement(webdriver.By.name('q')).sendKeys('webdriver');
driver.findElement(webdriver.By.name('btnG')).click();
driver.getTitle().then(function(title) {
console.log(title);
});
driver.quit();

You need to export the User.name
field so that the json
package can see it. Rename the name
field to Name
.
package main
import (
"fmt"

)
type User struct {
Name string
}
func main() {
user := &User{Name: "Frank"}
b, err := json.Marshal(user)
if err != nil {
fmt.Println(err)
return
}
fmt.Println(string(b))
}
Output:
{"Name":"Frank"}

Here's just an outline of the idea:
In a BST, the left subtree of node T
contains only elements smaller than the value stored in T
. If k
is smaller than the number of elements in the left subtree, the k
th smallest element must belong to the left subtree. Otherwise, if k
is larger, then the k
th smallest element is in the right subtree.
We can augment the BST to have each node in it store the number of elements in its left subtree (assume that the left subtree of a given node includes that node). With this piece of information, it is simple to traverse the tree by repeatedly asking for the number of elements in the left subtree, to decide whether to do recurse into the left or right subtree.
Now, suppose we are at node T:
T
.k
th smallest. So, we reduce the problem to finding the k - num_elements(left subtree of T)
smallest element of the right subtree. k
th smallest is somewhere in the left subtree, so we reduce the problem to finding the k
th smallest element in the left subtree.Complexity analysis:
This takes O(depth of node)
time, which is O(log n)
in the worst case on a balanced BST, or O(log n)
on average for a random BST.
A BST requires O(n)
storage, and it takes another O(n)
to store the information about the number of elements. All BST operations take O(depth of node)
time, and it takes O(depth of node)
extra time to maintain the "number of elements" information for insertion, deletion or rotation of nodes. Therefore, storing information about the number of elements in the left subtree keeps the space and time complexity of a BST.

A task is something you want done.
A thread is one of the many possible workers which performs that task.
In .NET 4.0 terms, a Task represents an asynchronous operation. Thread(s) are used to complete that operation by breaking the work up into chunks and assigning to separate threads.

There is a whole Section in the docs called 16.3.3.4 Mapping the request body with the @RequestBody annotation. And one called 16.3.3.5 Mapping the response body with the @ResponseBody annotation. I suggest you consult those sections. Also relevant: @RequestBody
javadocs, @ResponseBody
javadocs
Usage examples would be something like this:
Using a JavaScript-library like JQuery, you would post a JSON-Object like this:
{ "firstName" : "Elmer", "lastName" : "Fudd" }
Your controller method would look like this:
// controller
@ResponseBody @RequestMapping("/description")
public Description getDescription(@RequestBody UserStats stats){
return new Description(stats.getFirstName() + " " + stats.getLastname() + " hates wacky wabbits");
}
// domain / value objects
public class UserStats{
private String firstName;
private String lastName;
// + getters, setters
}
public class Description{
private String description;
// + getters, setters, constructor
}
Now if you have Jackson on your classpath (and have an <mvc:annotation-driven>
setup), Spring would convert the incoming JSON to a UserStats object from the post body (because you added the @RequestBody
annotation) and it would serialize the returned object to JSON (because you added the @ResponseBody
annotation). So the Browser / Client would see this JSON result:
{ "description" : "Elmer Fudd hates wacky wabbits" }
See this previous answer of mine for a complete working example: https://stackoverflow.com/a/5908632/342852
Note: RequestBody / ResponseBody is of course not limited to JSON, both can handle multiple formats, including plain text and XML, but JSON is probably the most used format.
Ever since Spring 4.x, you usually won't use @ResponseBody
on method level, but rather @RestController
on class level, with the same effect.
Here is a quote from the official Spring MVC documentation:
@RestController
is a composed annotation that is itself meta-annotated with@Controller
and@ResponseBody
to indicate a controller whose every method inherits the type-level@ResponseBody
annotation and, therefore, writes directly to the response body versus view resolution and rendering with an HTML template.
Looks like problem of configuration for maven compiler in your pom file. Default version java source and target is 1.5, even used JDK has higher version.

Saudate, I ran across this looking for a different problem. You most definitely can use the Sql Server Import wizard to import data into a new table. Of course, you do not wish to leave that table in the database, so my suggesting is that you import into a new table, then script the data in query manager to insert into the existing table. You can add a line to drop the temp table created by the import wizard as the last step upon successful completion of the script.
I believe your original issue is in fact related to Sql Server 64 bit and is due to your having a 32 bit Excel and these drivers don't play well together. I did run into a very similar issue when first using 64 bit excel.

You get all the features you want for graphics manipulation, but there's also vector graphics and even support for real printers. And all of that in one uniform API, QPainter
.
To use Qt you need a Python binding for it: PySide or PyQt4.
They both support Python 3.
Here is a simple example that loads a JPG image, draws an antialiased circle of radius 10 at coordinates (20, 20) with the color of the pixel that was at those coordinates and saves the modified image as a PNG file:
from PySide.QtCore import *
from PySide.QtGui import *
app = QCoreApplication([])
img = QImage('input.jpg')
g = QPainter(img)
g.setRenderHint(QPainter.Antialiasing)
g.setBrush(QColor(img.pixel(20, 20)))
g.drawEllipse(QPoint(20, 20), 10, 10)
g.end()
img.save('output.png')
But please note that this solution is quite 'heavyweight', because Qt is a large framework for making GUI applications.
write() only takes a single string argument, so you could do this:
outf.write(str(num))
or
outf.write('{}'.format(num)) # more "modern"
outf.write('%d' % num) # deprecated mostly
Also note that write
will not append a newline to your output so if you need it you'll have to supply it yourself.
Aside:
Using string formatting would give you more control over your output, so for instance you could write (both of these are equivalent):
num = 7
outf.write('{:03d}\n'.format(num))
num = 12
outf.write('%03d\n' % num)
to get three spaces, with leading zeros for your integer value followed by a newline:
007
012
format() will be around for a long while, so it's worth learning/knowing.
BLOB
primarily intended to hold non-traditional data, such as images,videos,voice or mixed media. CLOB
intended to retain character-based data.
@chepner make a good point that logger
is dedicated to logging messages.
I do need to mention that @Thomas Haratyk simply inquired why I didn't simply use echo
.
At the time, I didn't know about echo, as I'm learning shell-scripting
, but he was right.
My simple solution is now this:
#!/bin/bash
echo "This logs to where I want, but using echo" > /var/log/mycustomlog
The example above will overwrite the file after the >
So, I can append to that file with this:
#!/bin/bash
echo "I will just append to my custom log file" >> /var/log/customlog
Thanks guys!
/var/log/
, but I'm sure there are other good ideas out there. And since I didn't create a daemon, /var/log/
probably isn't the best place for my custom log file. (just saying)Just wanted to point out that Haris's Answer might not work if some other background process is using the database, in my case it was delayed jobs, I did:
script/delayed_job stop
And only then I was able to drop/reset the database.
I was struggling with the same problem and found one solution. I guess it can help you. when you run python manage.py runserver, it will take 127.0.0.1 as default ip address and 8000. 127.0.0.0 is the same as localhost which can be accessed locally. to access it from cross origin you need to run it on your system ip or 0.0.0.0. 0.0.0.0 can be accessed from any origin in the network. for port number, you need to set inbound and outbound policy of your system if you want to use your own port number not the default one.
To do this you need to run server with command python manage.py runserver 0.0.0.0:<your port>
as mentioned above
or, set a default ip and port in your python environment. For this see my answer on django change default runserver port

From time to time I present MR concepts to people. I find processing tasks familiar to people and then map them to the MR paradigm.
Usually I take two things:
Group By / Aggregations. Here the advantage of the shuffling stage is clear. An explanation that shuffling is also distributed sort + an explanation of distributed sort algorithm also helps.
Join of two tables. People working with DB are familiar with the concept and its scalability problem. Show how it can be done in MR.
You're not far; you need to do something like this:
[WebMethod]
public static string GetProducts()
{
// instantiate a serializer
JavaScriptSerializer TheSerializer = new JavaScriptSerializer();
//optional: you can create your own custom converter
TheSerializer.RegisterConverters(new JavaScriptConverter[] {new MyCustomJson()});
var products = context.GetProducts().ToList();
var TheJson = TheSerializer.Serialize(products);
return TheJson;
}
You can reduce this code further but I left it like that for clarity. In fact, you could even write this:
return context.GetProducts().ToList();
and this would return a json string. I prefer to be more explicit because I use custom converters. There's also Json.net but the framework's JavaScriptSerializer
works just fine out of the box.
import string
asking = "".join(l for l in asking if l not in string.punctuation)
filter with string.punctuation
.
For one who is using macOS, the new version just can be installed by homebrew. so for resting, this command line must be using:
brew services restart jenkins-lts
With H, S,and L in [0,1] range:
ConvertHslToRgb: function (iHsl)
{
var min, sv, sextant, fract, vsf;
var v = (iHsl.l <= 0.5) ? (iHsl.l * (1 + iHsl.s)) : (iHsl.l + iHsl.s - iHsl.l * iHsl.s);
if (v === 0)
return { Red: 0, Green: 0, Blue: 0 };
min = 2 * iHsl.l - v;
sv = (v - min) / v;
var h = (6 * iHsl.h) % 6;
sextant = Math.floor(h);
fract = h - sextant;
vsf = v * sv * fract;
switch (sextant)
{
case 0: return { r: v, g: min + vsf, b: min };
case 1: return { r: v - vsf, g: v, b: min };
case 2: return { r: min, g: v, b: min + vsf };
case 3: return { r: min, g: v - vsf, b: v };
case 4: return { r: min + vsf, g: min, b: v };
case 5: return { r: v, g: min, b: v - vsf };
}
}
Recently I had the same problem when using htmlTable() (‘htmlTable’ package) and I found a simpler solution: convert the data frame to a matrix with as.matrix():
htmlTable(as.matrix(df))
And be sure that the rownames are just indices. as.matrix() conservs the same columnames. That's it.
Following the comment of @DMR, I did't notice that htmlTable()
has the parameter rnames = FALSE
for cases like this. So a better answer would be:
htmlTable(df, rnames = FALSE)
This is by far is the best way, it requires no extra plugins.

I love Stack Overflow:
I realized that some time being too specific is not enough that is because we may have different Xcode version, I have 2 xcode version on the same Mac Pro myself. So here I would like to provide a general instruction that i hope it will work for all Xcode version:
My 2 versions are xcode 3.2.6 and 4.0. You need to find (even google for the settings) your xcode BUILD SETTINGS and its CODE SIGNING under CODE SIGNING you have CODE SIGN IDENTITY this provide you a list of IDENTIFIERS (if you do not have IDENTIFIERS go here to get one and registration is required https://developer.apple.com/ios/manage/overview/index.action - follow this instruction of Apple "Get your application on an iOS with the Development Provisioning Assistant") If you have a list of identifiers just select a valid one and run your Xcode again. It will work!
3.2.6 specific: On your scode window - click on Project -> Project settings -> Build (tab) -> there is a scroll down because the list is long MAKING SURE you scroll down to find your CODE SIGNING section
4.0 specific: On your xcode window - click on your project file left most colum -> then next colum click on your target app -> find CODE SIGNING and assign an IDENTIFIER. It should work for you.
Done!
There is no overload for DateTime values, but you can get the long value Ticks
that is what the values contain, compare them and then create a new DateTime value from the result:
new DateTime(Math.Min(Date1.Ticks, Date2.Ticks))
(Note that the DateTime structure also contains a Kind
property, that is not retained in the new value. This is normally not a problem; if you compare DateTime values of different kinds the comparison doesn't make sense anyway.)
In the case of swift 2.0 on iOS 9
Place the following in the app delegate, under didFinishLaunchingWithOptions:
let view: UIView = UIView.init(frame: CGRectMake(0, 0, UIScreen.mainScreen().bounds.size.width, 20))
view.backgroundColor = UIColor.blackColor() //The colour you want to set
view.alpha = 0.1 //This and the line above is set like this just if you want
the status bar a darker shade of
the colour you already have behind it.
self.window!.rootViewController!.view.addSubview(view)
With Android Studio 0.6.1+ (and possibly earlier) you can easily develop standard Java (non-Android) apps.
This method has been tested on 0.8.2:
Start by creating a vanilla Android Phone app, using File > New Project. Then add a Java Library module to hold your Java Application code. (Choose 'Java Library' even if you're building an application). You'll find you can build and run Java apps with main()
methods, Swing apps etc.
You'll want to delete the auto-generated Android "app" module, which you're not using. Go to File -> Project Structure, and delete it (select the "app" module in the box on the left, and click the 'minus' icon above the box). Now when you reopen File -> Project Structure -> Project, you'll see options for selecting the project SDK and language level, plus a bunch of other options that were previously hidden. You can go ahead and delete the "app" module from the disk.
In 0.6.1 you could avoid creating the android module in the first place:
Go to File > New Project. Fill in your application name. On the "form factors" selection page, where you state your minimum Android SDK, deselect the Mobile checkbox, and proceed with creating your project.
Once the project is created, go to File -> Project Structure -> Project, and set your JDK as the "Project SDK". Add a Java Library module to hold your application code as above.
I also had this problem. If you also have Visual Studio installed with the Python extension, the system will want to use Studio's version of Python. Set the Environment Path to the version in Studio's Shared folder. For me, that was:
C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python36_64\
After that, run
python -m pip install pylint
from a command prompt with Administrator rights.
The error is:
Can not deserialize instance of java.lang.String out of START_ARRAY token at [Source: line: 1, column: 1095] (through reference chain: JsonGen["platforms"])
In JSON, platforms
look like this:
"platforms": [
{
"platform": "iphone"
},
{
"platform": "ipad"
},
{
"platform": "android_phone"
},
{
"platform": "android_tablet"
}
]
So try change your pojo to something like this:
private List platforms;
public List getPlatforms(){
return this.platforms;
}
public void setPlatforms(List platforms){
this.platforms = platforms;
}
EDIT: you will need change mobile_networks
too. Will look like this:
private List mobile_networks;
public List getMobile_networks() {
return mobile_networks;
}
public void setMobile_networks(List mobile_networks) {
this.mobile_networks = mobile_networks;
}
You start looking near that code that you know ran, and you stop looking when you reach the code you know didn't run.
What you're looking for is probably some place where your program calls a function through a function pointer, but that pointer is null.
It's also possible you have stack corruption. You might have overwritten a function's return address with zero, and the exception occurs at the end of the function. Check for possible buffer overflows, and if you are calling any DLL functions, make sure you used the right calling convention and parameter count.
This isn't an ordinary case of using a null pointer, like an unassigned object reference or PChar. In those cases, you'll have a non-zero "at address x" value. Since the instruction occurred at address zero, you know the CPU's instruction pointer was not pointing at any valid instruction. That's why the debugger can't show you which line of code caused the problem — there is no line of code. You need to find it by finding the code that lead up to the place where the CPU jumped to the invalid address.
The call stack might still be intact, which should at least get you pretty close to your goal. If you have stack corruption, though, you might not be able to trust the call stack.
the difference of the numbers put in system.exit() is explained in other answers. but the REAL DIFFERENCE is that System.exit() is a code that gets returned to the invoking process. If the program is being invoked by the Operating system then the return code will tell the OS that if system.exit() returned 0 than everything was ok but if not something went wrong, then there could be some handlers for that in the parent process
You can also give weight separately like this ,
LayoutParams lp1 = new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT);
lp1.weight=1;
If you are using the ThreeTen backport for Android and can't use the newer Date.from(Instant instant)
(which requires minimum of API 26) you can use:
ZonedDateTime zdt = ZonedDateTime.now();
Date date = new Date(zdt.toInstant().toEpochMilli());
or:
Date date = DateTimeUtils.toDate(zdt.toInstant());
Please also read the advice in Basil Bourque's answer
Run this code, it will fetch data from file and display in console
function fileread(filename)
{
var contents= fs.readFileSync(filename);
return contents;
}
var fs =require("fs"); // file system
var data= fileread("abc.txt");
//module.exports.say =say;
//data.say();
console.log(data.toString());
Every distribution has a default shell. Bash is the default on the majority of the systems. If you happen to work on a system that has a different default shell, then the scripts might not work as intended if they are written specific for Bash.
Bash has evolved over the years taking code from ksh
and sh
.
Adding #!/bin/bash
as the first line of your script, tells the OS to invoke the specified shell
to execute the commands that follow in the script.
#!
is often referred to as a "hash-bang", "she-bang" or "sha-bang".
As mentioned here, markdown do not support right aligned text or blocks. But the HTML result does it, via Cascading Style Sheets (CSS).
On my Jekyll Blog is use a syntax which works in markdown as well. To "terminate" a block use two spaces at the end or two times new line.
Of course you can also add a css-class with {: .right }
instead of {: style="text-align: right" }
.
Text to right
{: style="text-align: right" }
This text is on the right
Text as block
{: style="text-align: justify" }
This text is a block
First of all i say that you should google this as it is defined in detail in many places
Local
These variables only exist inside the specific function that creates them. They are unknown to other functions and to the main program. As such, they are normally implemented using a stack. Local variables cease to exist once the function that created them is completed. They are recreated each time a function is executed or called.
Global
These variables can be accessed (ie known) by any function comprising the program. They are implemented by associating memory locations with variable names. They do not get recreated if the function is recalled.
/* Demonstrating Global variables */
#include <stdio.h>
int add_numbers( void ); /* ANSI function prototype */
/* These are global variables and can be accessed by functions from this point on */
int value1, value2, value3;
int add_numbers( void )
{
auto int result;
result = value1 + value2 + value3;
return result;
}
main()
{
auto int result;
value1 = 10;
value2 = 20;
value3 = 30;
result = add_numbers();
printf("The sum of %d + %d + %d is %d\n",
value1, value2, value3, final_result);
}
Sample Program Output
The sum of 10 + 20 + 30 is 60
The scope of global variables can be restricted by carefully placing the declaration. They are visible from the declaration until the end of the current source file.
#include <stdio.h>
void no_access( void ); /* ANSI function prototype */
void all_access( void );
static int n2; /* n2 is known from this point onwards */
void no_access( void )
{
n1 = 10; /* illegal, n1 not yet known */
n2 = 5; /* valid */
}
static int n1; /* n1 is known from this point onwards */
void all_access( void )
{
n1 = 10; /* valid */
n2 = 3; /* valid */
}
Static:
Static object is an object that persists from the time it's constructed until the end of the program. So, stack and heap objects are excluded. But global objects, objects at namespace scope, objects declared static inside classes/functions, and objects declared at file scope are included in static objects. Static objects are destroyed when the program stops running.
I suggest you to see this tutorial list
AUTO:
C, C++
(Called automatic variables.)
All variables declared within a block of code are automatic by default, but this can be made explicit with the auto keyword.[note 1] An uninitialized automatic variable has an undefined value until it is assigned a valid value of its type.[1]
Using the storage class register instead of auto is a hint to the compiler to cache the variable in a processor register. Other than not allowing the referencing operator (&) to be used on the variable or any of its subcomponents, the compiler is free to ignore the hint.
In C++, the constructor of automatic variables is called when the execution reaches the place of declaration. The destructor is called when it reaches the end of the given program block (program blocks are surrounded by curly brackets). This feature is often used to manage resource allocation and deallocation, like opening and then automatically closing files or freeing up memory.SEE WIKIPEDIA

{
MessageboxNew msg = new MessageboxNew
{
TitleBar = {Text = title},
Textbar = {Text = text}

dex2jar helps to decompile your apk but not 100%. You will have some problems with .smali files. Dex2jar cannot convert it to java. I know one application that can decompile your apk source files and no problems with .smali files. Here is a link http://www.hensence.com/en/smali2java/
For me, the mysql server was not running. So, i started the mysql server through
mysql.server start
then
mysql_secure_installation
to secure the server and now I can visit the MySQL server through
mysql -u root -p
or
sudo mysql -u root -p
depending on your installation.
There is a button Download ZIP
. If you want to do a sparse checkout there are many solutions on the site. For example here.
One thing you can do is get rid of all those onclick attributes and do it the right way with bootstrap. You don't need to open them manually; you can specify the trigger and even subscribe to events before the modal opens so that you can do your operations and populate data in it.
I am just going to show as a static example which you can accommodate in your real world.
On each of your <tr>
's add a data attribute for id
(i.e. data-id
) with the corresponding id value and specify a data-target
, which is a selector you specify, so that when clicked, bootstrap will select that element as modal dialog and show it. And then you need to add another attribute data-toggle=modal
to make this a trigger for modal.
<tr data-toggle="modal" data-id="1" data-target="#orderModal">
<td>1</td>
<td>24234234</td>
<td>A</td>
</tr>
<tr data-toggle="modal" data-id="2" data-target="#orderModal">
<td>2</td>
<td>24234234</td>
<td>A</td>
</tr>
<tr data-toggle="modal" data-id="3" data-target="#orderModal">
<td>3</td>
<td>24234234</td>
<td>A</td>
</tr>
And now in the javascript just set up the modal just once and event listen to its events so you can do your work.
$(function(){
$('#orderModal').modal({
keyboard: true,
backdrop: "static",
show:false,
}).on('show', function(){ //subscribe to show method
var getIdFromRow = $(event.target).closest('tr').data('id'); //get the id from tr
//make your ajax call populate items or what even you need
$(this).find('#orderDetails').html($('<b> Order Id selected: ' + getIdFromRow + '</b>'))
});
});
Do not use inline click attributes any more. Use event bindings instead with vanilla js or using jquery.
Alternative ways here:
Ranking by stars or forks is not working. Each promoted or created by a famous company repository is popular at the beginning. Also it is possible to have a number of them which are in trend right now (publications, marketing, events). It doesn't mean that those repositories are useful/popular.
The gitmostwanted.com project (repo at github) analyses GH Archive data in order to highlight the most interesting repositories and exclude others. Just compare the results with mentioned resources.
Actually, there are many issues with different environments, python versions, so on. You might also need to install python dev files, so to 'brute-force' the installation I would run all of these:
sudo apt-get install python-dev python3-dev
sudo apt-get install libmysqlclient-dev
pip install MySQL-python
pip install pymysql
pip install mysqlclient
You should be good to go with the accepted answer. And can remove the unnecessary packages if that's important to you.
A generic, pure Java solution..
For Windows and MacOS, the following can be inferred (most of the time)...
public static boolean isJDK() {
String path = System.getProperty("sun.boot.library.path");
if(path != null && path.contains("jdk")) {
return true;
}
return false;
}
However... on Linux this isn't as reliable... For example...
openjdk
the pathSo a more fail-safe approach is to check for the existence of the javac
executable.
public static boolean isJDK() {
String path = System.getProperty("sun.boot.library.path");
if(path != null) {
String javacPath = "";
if(path.endsWith(File.separator + "bin")) {
javacPath = path;
} else {
int libIndex = path.lastIndexOf(File.separator + "lib");
if(libIndex > 0) {
javacPath = path.substring(0, libIndex) + File.separator + "bin";
}
}
if(!javacPath.isEmpty()) {
return new File(javacPath, "javac").exists() || new File(javacPath, "javac.exe").exists();
}
}
return false;
}
Warning: This will still fail for JRE + JDK combos which report the JRE's sun.boot.library.path
identically between the JRE and the JDK. For example, Fedora's JDK will fail (or pass depending on how you look at it) when the above code is run. See unit tests below for more info...
Unit tests:
# Unix
java -XshowSettings:properties -version 2>&1|grep "sun.boot.library.path"
# Windows
java -XshowSettings:properties -version 2>&1|find "sun.boot.library.path"

Via native JS, to add one day you may do following:
let date = new Date(); // today
date.setDate(date.getDate() + 1) // tomorrow
Another option is to use moment
library:
const date = moment().add(14, "days").toDate()
Below are two different browser APIs that can transform Numbers into structured Strings. Keep in mind that not all users' machines have a locale that uses commas in numbers. To enforce commas to the output, any "western" locale may be used, such as en-US
var number = 1234567890; // Example number to be converted
?? Mind that javascript has a maximum integer value of 9007199254740991
// default behaviour on a machine with a local that uses commas for numbers
number.toLocaleString(); // "1,234,567,890"
// With custom settings, forcing a "US" locale to guarantee commas in output
var number2 = 1234.56789; // floating point example
number2.toLocaleString('en-US', {maximumFractionDigits:2}) // "1,234.57"
var nf = new Intl.NumberFormat();
nf.format(number); // "1,234,567,890"
From what I checked (Firefox at least) they are both more or less same regarding performance.
Live demo: https://codepen.io/vsync/pen/MWjdbgL?editors=1000
Ex: In web.xml file the tag
<context-param>
<param-name>chatpropertyfile</param-name>
<!-- Name of the chat properties file. It contains the name and description of rooms.-->
<param-value>chat.properties</param-value>
</context-param>
And chat.properties you can declare your properties like this
For Ex :
Jsp = Discussion about JSP can be made here.
Java = Talk about java and related technologies like J2EE.
ASP = Discuss about Active Server Pages related technologies like VBScript and JScript etc.
Web_Designing = Any discussion related to HTML, JavaScript, DHTML etc.
StartUp = Startup chat room. Chatter is added to this after he logs in.
Java documentation is helpful to know the root cause of a particular IOException.
Just have a look at the direct known sub-interfaces of IOException
from the documentation page:
ChangedCharSetException, CharacterCodingException, CharConversionException, ClosedChannelException, EOFException, FileLockInterruptionException, FileNotFoundException, FilerException, FileSystemException, HttpRetryException, IIOException, InterruptedByTimeoutException, InterruptedIOException, InvalidPropertiesFormatException, JMXProviderException, JMXServerErrorException, MalformedURLException, ObjectStreamException, ProtocolException, RemoteException, SaslException, SocketException, SSLException, SyncFailedException, UnknownHostException, UnknownServiceException, UnsupportedDataTypeException, UnsupportedEncodingException, UserPrincipalNotFoundException, UTFDataFormatException, ZipException
Most of these exceptions are self-explanatory.
A few IOExceptions
with root causes:
EOFException: Signals that an end of file or end of stream has been reached unexpectedly during input. This exception is mainly used by data input streams to signal the end of the stream.
SocketException: Thrown to indicate that there is an error creating or accessing a Socket.
RemoteException: A RemoteException is the common superclass for a number of communication-related exceptions that may occur during the execution of a remote method call. Each method of a remote interface, an interface that extends java.rmi.Remote, must list RemoteException in its throws clause.
UnknownHostException: Thrown to indicate that the IP address of a host could not be determined (you may not be connected to Internet).
MalformedURLException: Thrown to indicate that a malformed URL has occurred. Either no legal protocol could be found in a specification string or the string could not be parsed.
In my case:
Project properties ? Project Facets. Make sure "Dynamic Web Module" is checked. Finally, I enter the version number "2.3" instead of "3.0". After that, the Apache Tomcat 5.5 runtime is listed in the "Runtimes" tab.
You can always add the "!" into your float-options. This way, latex tries really hard to place the figure where you want it (I mostly use [h!tb]), stretching the normal rules of type-setting.
I have found another solution:
Use the float-package. This way you can place the figures where you want them to be.
generally, I make by simple way, whatever, I create a restAPI endpoint for example "localhost/api/method/:lastIdObtained/:countDateToReturn" with theses parameters, you can do it a simple request. in the service, eg. .net
jsonData function(lastIdObtained,countDatetoReturn){
'... write your code as you wish..'
and into select query make a filter
select top countDatetoreturn tt.id,tt.desc
from tbANyThing tt
where id > lastIdObtained
order by id
}
In Ionic, when I scroll from bottom to top, I pass the zero value, when I get the answer, I set the value of the last id obtained, and when I slide from top to bottom, I pass the last registration id I got
String[] split = data.split("\\|",-1);
This is not the actual requirement in all the time. The Drawback of above is show below:
Scenerio 1:
When all data are present:
String data = "5|6|7||8|9|10|";
String[] split = data.split("\\|");
String[] splt = data.split("\\|",-1);
System.out.println(split.length); //output: 7
System.out.println(splt.length); //output: 8
When data is missing:
Scenerio 2: Data Missing
String data = "5|6|7||8|||";
String[] split = data.split("\\|");
String[] splt = data.split("\\|",-1);
System.out.println(split.length); //output: 5
System.out.println(splt.length); //output: 8
Real requirement is length should be 7 although there is data missing. Because there are cases such as when I need to insert in database or something else. We can achieve this by using below approach.
String data = "5|6|7||8|||";
String[] split = data.split("\\|");
String[] splt = data.replaceAll("\\|$","").split("\\|",-1);
System.out.println(split.length); //output: 5
System.out.println(splt.length); //output:7
What I've done here is, I'm removing "|" pipe at the end and then splitting the String. If you have "," as a seperator then you need to add ",$" inside replaceAll.
1) goto html view
2) type iframe and find your required frame and count the value and switch to it using
oASelFW.driver.switchTo().frame(2);
if it is first frame then use oASelFW.driver.switchTo().frame(0);
if it is second frame then use oASelFW.driver.switchTo().frame(1);
respectively
I tried following command and it works fine
conda install -c conda-forge opencv
once you hit the command it will ask for yes or no
If you select yes it will proceed and install all the required packages
Most of these answers use sp_executesql as the solution to this problem. I have found that there are some limitations when using sp_executesql, which I will not go into, but I wanted to offer an alternative using EXEC(). I am using SQL Server 2008 and I know that some of the objects I am using in this script are not available in earlier versions of SQL Server so be wary.
DECLARE @CountResults TABLE (CountReturned INT)
DECLARE
@SqlStatement VARCHAR(8000) = 'SELECT COUNT(*) FROM table'
, @Count INT
INSERT @CountResults
EXEC(@SqlStatement)
SET @Count = (SELECT CountReturned FROM @CountResults)
SELECT @Count
This solved my problem : Sample alter table statement to change the ownership.
ALTER TABLE databasechangelog OWNER TO arwin_ash;
ALTER TABLE databasechangeloglock OWNER TO arwin_ash;
I had this issue on arch linux as well. The issue was pacman installed the package in a different location than MySQL was expecting. I was able to fix the issue with this:
sudo mysql_install_db --user=mysql --basedir=/usr/ --ldata=/var/lib/mysql/
Hope this helps someone!
The commercial solution, SpreadsheetGear for .NET will do it.
You can see live ASP.NET (C# and VB) samples here and download an evaluation version here.

First of all, you should make an HTML form containing a file input element. You also need to set the form's enctype attribute to multipart/form-data:
<form method="post" enctype="multipart/form-data" action="/upload">
<input type="file" name="file">
<input type="submit" value="Submit">
</form>
Assuming the form is defined in index.html stored in a directory named public relative to where your script is located, you can serve it this way:
const http = require("http");
const path = require("path");
const fs = require("fs");
const express = require("express");
const app = express();
const httpServer = http.createServer(app);
const PORT = process.env.PORT || 3000;
httpServer.listen(PORT, () => {
console.log(`Server is listening on port ${PORT}`);
});
// put the HTML file containing your form in a directory named "public" (relative to where this script is located)
app.get("/", express.static(path.join(__dirname, "./public")));
Once that's done, users will be able to upload files to your server via that form. But to reassemble the uploaded file in your application, you'll need to parse the request body (as multipart form data).
In Express 3.x you could use express.bodyParser
middleware to handle multipart forms but as of Express 4.x, there's no body parser bundled with the framework. Luckily, you can choose from one of the many available multipart/form-data parsers out there. Here, I'll be using multer:
You need to define a route to handle form posts:
const multer = require("multer");
const handleError = (err, res) => {
res
.status(500)
.contentType("text/plain")
.end("Oops! Something went wrong!");
};
const upload = multer({
dest: "/path/to/temporary/directory/to/store/uploaded/files"
// you might also want to set some limits: https://github.com/expressjs/multer#limits
});
app.post(
"/upload",
upload.single("file" /* name attribute of <file> element in your form */),
(req, res) => {
const tempPath = req.file.path;
const targetPath = path.join(__dirname, "./uploads/image.png");
if (path.extname(req.file.originalname).toLowerCase() === ".png") {
fs.rename(tempPath, targetPath, err => {
if (err) return handleError(err, res);
res
.status(200)
.contentType("text/plain")
.end("File uploaded!");
});
} else {
fs.unlink(tempPath, err => {
if (err) return handleError(err, res);
res
.status(403)
.contentType("text/plain")
.end("Only .png files are allowed!");
});
}
}
);
In the example above, .png files posted to /upload will be saved to uploaded directory relative to where the script is located.
In order to show the uploaded image, assuming you already have an HTML page containing an img element:
<img src="/image.png" />
you can define another route in your express app and use res.sendFile
to serve the stored image:
app.get("/image.png", (req, res) => {
res.sendFile(path.join(__dirname, "./uploads/image.png"));
});

use DateTime.ParseExact
string strDate = "24/01/2013";
DateTime date = DateTime.ParseExact(strDate, "dd/MM/YYYY", null)
null
will use the current culture, which is somewhat dangerous. Try to supply a specific culture
DateTime date = DateTime.ParseExact(strDate, "dd/MM/YYYY", CultureInfo.InvariantCulture)
For Example, in your HTML:
<body>
<svg viewBox="" width="" height="">
<path id="struct1" fill="#xxxxxx" d="M203.3,71.6c-.........."></path>
</svg>
</body>
Use jQuery:
$("#struct1").css("fill","<desired colour>");
It's additional information, and isn't an answer.
In C++11 you can write:
for (auto& it : s) {
cout << it << endl;
}
instead of
for (auto it = s.begin(); it != s.end(); it++) { cout << *it << endl; }
It has the same meaning.
Update: See the @Alnitak's comment also.
The biggest benefit is that the code is more succinct. The VS editor will also have the IntelliSense support that some of the other view engines don't have.
Declarative HTML Helpers also look pretty cool as doing HTML helpers within C# code reminds me of custom controls in ASP.NET. I think they took a page from partials but with the inline code.
So some definite benefits over the asp.net view engine.
With contrast to a view engine like spark though:
Spark is still more succinct, you can keep the if's and loops within a html tag itself. The markup still just feels more natural to me.
You can code partials exactly how you would do a declarative helper, you'd just pass along the variables to the partial and you have the same thing. This has been around with spark for quite awhile.
If you treat the content as text, not HTML, then DOM operations should cause the data to be properly encoded. Here's how you'd do it in jQuery:
$('#container').text(xmlString);
Here's how you'd do it with standard DOM methods:
document.getElementById('container')
.appendChild(document.createTextNode(xmlString));
If you're placing the XML inside of HTML through server-side scripting, there are bound to be encoding functions to allow you to do that (if you add what your server-side technology is, we can give you specific examples of how you'd do it).
$_GET
contains the keys / values that are passed to your script in the URL.
If you have the following URL :
http://www.example.com/test.php?a=10&b=plop
Then $_GET
will contain :
array
'a' => string '10' (length=2)
'b' => string 'plop' (length=4)
Of course, as $_GET
is not read-only, you could also set some values from your PHP code, if needed :
$_GET['my_value'] = 'test';
But this doesn't seem like good practice, as $_GET
is supposed to contain data from the URL requested by the client.
Working with Intellij, because I don't know how to set keyboard shortcut to mvn spring-boot:run -Dspring.profiles.active=dev
, I have to do this:

<groupId>org.springframework.boot</groupId>

-Dspring.profiles.active=dev
</jvmArguments>

If you are in android studio 3.1, Verify if file->Project Structure -> Source compatibility is empty. it should not have 1.8 set.
then press ok, the project will sync and error will disappear.
It's the correct way to access linked DB:
EXEC [ServerName].[DatabaseName].dbo.sp_HelpText 'storedProcName'
But make sure to mention dbo
as it owns the sp_helptext
.
Thanks a lot it worked , please note I did a typo in php as it should be mysqli_query( $con2, $sql )
Query for just a single known column:
session.query(MyTable.col1).count()
Keep in mind that the copy constructor limits the class type to that of the copy constructor. Consider the example:
// Need to clone person, which is type Person
Person clone = new Person(person);
This doesn't work if person
could be a subclass of Person
(or if Person
is an interface). This is the whole point of clone, is that it can can clone the proper type dynamically at runtime (assuming clone is properly implemented).
Person clone = (Person)person.clone();
or
Person clone = (Person)SomeCloneUtil.clone(person); // See Bozho's answer
Now person
can be any type of Person
assuming that clone
is properly implemented.
Just to point out that there is an approach using functions from the tidyverse
, which I find more readable than gsub
:
a %>% stringr::str_remove(pattern = ".*_")
5 years later-version:
Today, there are JS libraries for you, if you don't want to get into the nitty gritty of the different methods described on this page.
On of these is https://github.com/hubspot/offline. It checks for the connectivity of a pre-defined URI, by default your favicon. It automatically detects when the user's connectivity has been reestablished and provides neat events like up
and down
, which you can bind to in order to update your UI.

Set cn = CreateObject("ADODB.Connection")
strConnection = "Provider=Microsoft.ACE.OLEDB.12.0;" & _
"Data Source=C:\Documents and Settings\XXXXXX\My Documents\my_access_table.accdb"
strSql = "SELECT Count(*) FROM mytable;"
cn.Open strConnection
Set rs = cn.Execute(strSql)
MsgBox rs.Fields(0) & " rows in MyTable"
rs.Close
Set rs = Nothing

If you're working with Visual Studio then follow these steps to access the IIS-Express over IP-Adress:
ipconfig
in Windows Command LineGoTo
$(SolutionDir)\.vs\config\applicationHost.config
Find
<site name="WebApplication3" id="2">
<application path="/" applicationPool="Clr4IntegratedAppPool">
<virtualDirectory path="/" physicalPath="C:\Users\user.name\Source\Repos\protoype-one\WebApplication3" />
</application>
<bindings>
<binding protocol="http" bindingInformation="*:62549:localhost" />
</bindings>
</site>
Add:
<binding protocol="http" bindingInformation="*:62549:192.168.178.108"/>
with your IP-Adress
I tried the below solution and it work fine for me.

Tried below phone format:
Unfortunately, modules aren't supported by many browsers right now.
This feature is only just beginning to be implemented in browsers natively at this time. It is implemented in many transpilers, such as TypeScript and Babel, and bundlers such as Rollup and Webpack.

Here is a summary.
escape() will not encode @ * _ + - . /
Do not use it.
encodeURI() will not encode A-Z a-z 0-9 ; , / ? : @ & = + $ - _ . ! ~ * ' ( ) #
Use it when your input is a complete URL like 'https://searchexample.com/search?q=wiki'
const queryStr = encodeURIComponent(someString)
The difflib library is useful for this, and comes in the standard library. I like the unified diff format.
http://docs.python.org/2/library/difflib.html#difflib.unified_diff
import difflib
import sys
with open('/tmp/hosts0', 'r') as hosts0:
with open('/tmp/hosts1', 'r') as hosts1:
diff = difflib.unified_diff(
hosts0.readlines(),
hosts1.readlines(),
fromfile='hosts0',
tofile='hosts1',
)
for line in diff:
sys.stdout.write(line)
Outputs:
--- hosts0
+++ hosts1
@@ -1,5 +1,4 @@
one
two
-dogs
three
And here is a dodgy version that ignores certain lines. There might be edge cases that don't work, and there are surely better ways to do this, but maybe it will be good enough for your purposes.
import difflib
import sys
with open('/tmp/hosts0', 'r') as hosts0:
with open('/tmp/hosts1', 'r') as hosts1:
diff = difflib.unified_diff(
hosts0.readlines(),
hosts1.readlines(),
fromfile='hosts0',
tofile='hosts1',
n=0,
)
for line in diff:
for prefix in ('---', '+++', '@@'):
if line.startswith(prefix):
break
else:
sys.stdout.write(line[1:])
How about the SQuirreL SQL Client? As mentioned in another SO question, this programs has the capability to generate a simple ER diagram.
After some googling, I found the advice to do the following, and it worked:
SQL> startup mount
ORACLE Instance started
SQL> recover database
Media recovery complete
SQL> alter database open;
Database altered
I (using PostgrSQL on PGadmin4) queried for results that are after or on 21st Nov 2017 at noon, like this (considering the display format of hours on my database):
select * from Table1 where FIELD >='2017-11-21 12:00:00'
This can also be done through the SSMS GUI. The nice thing about this method is it warns you if there are any relationships on that column and can also automatically delete those as well.
As I stated before, if there are any relationships that would also need to be deleted, it will ask you at this point if you would like to delete those as well. You will likely need to do so to delete the column.
If the original Service .InstallLog and .InstallState files are still in the folder, you can try reinstalling the executable to replace the files, then use InstallUtil /u, then uninstall the program. It's a bit convoluted, but worked in a particular instance for me.
I decided not to touch headers and make a redirect on the server side instead and it woks like a charm.
The example below is for the current version of Angular (currently 9) and probably any other framework using webpacks DevServer. But I think the same principle will work on other backends.
So I use the following configuration in the file proxy.conf.json:
{
"/api": {
"target": "http://localhost:3000",
"pathRewrite": {"^/api" : ""},
"secure": false
}
}
In case of Angular I serve with that configuration:
$ ng serve -o --proxy-config=proxy.conf.json
I prefer to use the proxy in the serve command, but you may also put this configuration to angular.json like this:
"architect": {
"serve": {
"builder": "@angular-devkit/build-angular:dev-server",
"options": {
"browserTarget": "your-application-name:build",
"proxyConfig": "src/proxy.conf.json"
},

I took @Dmitriusan's answer and made it into an alias:
alias docker-run-prev-container='prev_container_id="$(docker ps -aq | head -n1)" && docker commit "$prev_container_id" "prev_container/$prev_container_id" && docker run -it --entrypoint=bash "prev_container/$prev_container_id"'
Add this into your ~/.bashrc
aliases file, and you'll have a nifty new docker-run-prev-container
alias which'll drop you into a shell in the previous container.

As of jQuery 1.5, there is a headers
hash you can pass in as follows:
$.ajax({
url: "/test",
headers: {"X-Test-Header": "test-value"}
});
From http://api.jquery.com/jQuery.ajax:
headers (added 1.5): A map of additional header key/value pairs to send along with the request. This setting is set before the beforeSend function is called; therefore, any values in the headers setting can be overwritten from within the beforeSend function.
Kill the process that is listening to the port in question. I believe netstat shows you process ids.
This is also another good Home Screen script that support iphone/ipad, Mobile Safari, Android, Blackberry touch smartphones and Playbook .
https://github.com/h5bp/mobile-boilerplate/wiki/Mobile-Bookmark-Bubble
You can also do this in the Visual Studio debugger without modifying the code.
Of course, this doesn't help if you're running the code on a different machine, but it can be quite handy to be able to spit out a stack trace automatically without affecting release code or without even needing to restart the program.
The third argument is the XMLHttpRequest object, so you can do whatever you want.
$.ajax({
url : 'http://example.com',
type : 'post',
data : 'a=b'
}).done(function(data, statusText, xhr){
var status = xhr.status; //200
var head = xhr.getAllResponseHeaders(); //Detail header info
});
I generally use:
killall ruby
OR
pkill -9 ruby
which will kill all ruby related processes that are running like rails server
, rails console
, etc.
You can process any number of threads; there is no limit. I ran the following code while watching a movie and using NetBeans, and it worked properly/without halting the machine. I think you can keep even more threads than this program does.
class A extends Thread {
public void run() {
System.out.println("**************started***************");
for(double i = 0.0; i < 500000000000000000.0; i++) {
System.gc();
System.out.println(Thread.currentThread().getName());
}
System.out.println("************************finished********************************");
}
}
public class Manager {
public static void main(String[] args) {
for(double j = 0.0; j < 50000000000.0; j++) {
A a = new A();
a.start();
}
}
}
Use the throw statement.
JavaScript doesn't care what the exception type is (as Java does). JavaScript just notices, there's an exception and when you catch it, you can "look" what the exception "says".
If you have different exception types you have to throw, I'd suggest to use variables which contain the string/object of the exception i.e. message. Where you need it use "throw myException" and in the catch, compare the caught exception to myException.
use an unsigned long long (i.e. a 64 bit unit) to represent the system time:
typedef unsigned long long u64;
u64 u64useconds;
struct timeval tv;
gettimeofday(&tv,NULL);
u64useconds = (1000000*tv.tv_sec) + tv.tv_usec;
As per select2 documentation: Click Here
If you wants to disable select2 then use this approach:
$(".js-example-disabled").prop("disabled", true);
If you wants to enable a disabled select2 box use this approach:
$(".js-example-disabled").prop("disabled", false);
You can use cut with a delimiter like this:
with space delim:
cut -d " " -f1-100,1000-1005 infile.csv > outfile.csv
with tab delim:
cut -d$'\t' -f1-100,1000-1005 infile.csv > outfile.csv
I gave you the version of cut in which you can extract a list of intervals...
Hope it helps!
Liquibase was getting this error for me. I resolved this after I debugged and watched liquibase try to load the libraries and found that it was erroring on the manifest files for commons-codec-1.6.jar. Essentially, there is either a corrupt zip file somewhere in your path or there is a incompatible version being used. When I did an explore on Maven repository for this library, I found there were newer versions and added the newer version to the pom.xml. I was able to proceed at this point.
Groovy has operator overloading, and runs in the JVM. If you don't mind the performance hit (which gets smaller everyday). It's automatic based on method names. e.g., '+' calls the 'plus(argument)' method.
Strongly recommend this article.

You can get the selected row using the DataGridView.SelectedRows
Collection. If your DataGridView allows only one selected, have a look at my sample.
DataGridView.SelectedRows Gets the collection of rows selected by the user.
if (dataGridView1.SelectedRows.Count != 0)
{
DataGridViewRow row = this.dataGridView1.SelectedRows[0];
row.Cells["ColumnName"].Value
}
You need to make a second groupby object that groups by the states, and then use the div

tells pandas to broadcast/join the dataframes base on the values in the state
level of the index.
As noted by Mattias Nordqvist in the comments below, you can also select the radio button option "Run whether user is logged on or not". When saving the task, you will be prompted once for the user password. bambams noted that this wouldn't grant System permissions to the process, and also seems to hide the command window.
It's not an obvious solution, but to make a Scheduled Task run in the background, change the User running the task to "SYSTEM", and nothing will appear on your screen.
Easy Method is: Just copy the file cmd.exe from c:/windows/system32/ and paste it to C:\xampp\php\ and run it, when the cmd opens type " php -v " without quotes and hit enter... you will get your php version.. thank you
There are multiple ways to do this.
Events - already explained well.
ui router - explained above.

<superhero speed> Flash is here! </superhero>

app.directive('superhero', function(){

$scope.abilities.push("strength");
}
this.addSpeed = function(){

},
link: function(scope, element, attrs){
element.addClass('button');
element.on('mouseenter', function(){

It's the Return or Enter key on keyboard.
