To handle runtime permission google has provided a library project. You can check this from here https://github.com/googlesamples/easypermissions

EasyPermissions is installed by adding the following dependency to your build.gradle file:

dependencies {
compile 'pub.devrel:easypermissions:0.3.0'
}

To begin using EasyPermissions, have your Activity (or Fragment) override the onRequestPermissionsResult method:

public class MainActivity extends AppCompatActivity implements EasyPermissions.PermissionCallbacks {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);

    // Forward results to EasyPermissions
    EasyPermissions.onRequestPermissionsResult(requestCode, permissions, grantResults, this);
}

@Override
public void onPermissionsGranted(int requestCode, List<String> list) {
    // Some permissions have been granted
    // ...
}

@Override
public void onPermissionsDenied(int requestCode, List<String> list) {
    // Some permissions have been denied
    // ...
}
}

Here you will get a working example how this library works https://github.com/milon87/EasyPermission

your have to comment that line in ~/.bashrc:

#export PATH=/home/jolth/miniconda3/bin:$PATH

and run:

source ~/.bashrc

Change $_POST to $_FILES and make sure your enctype is "multipart/form-data"

Is your input field actually in a form?

<form method="POST" action="update.php">
    <input type="hidden" name="filename" value="test" />
</form>

Use this one

public static final MediaType APPLICATION_JSON_UTF8 = new MediaType(MediaType.APPLICATION_JSON.getType(), MediaType.APPLICATION_JSON.getSubtype(), Charset.forName("utf8"));

@Test
public void testInsertObject() throws Exception { 
    String url = BASE_URL + "/object";
    ObjectBean anObject = new ObjectBean();
    anObject.setObjectId("33");
    anObject.setUserId("4268321");
    //... more
    ObjectMapper mapper = new ObjectMapper();
    mapper.configure(SerializationFeature.WRAP_ROOT_VALUE, false);
    ObjectWriter ow = mapper.writer().withDefaultPrettyPrinter();
    String requestJson=ow.writeValueAsString(anObject );

    mockMvc.perform(post(url).contentType(APPLICATION_JSON_UTF8)
        .content(requestJson))
        .andExpect(status().isOk());
}

As described in the comments, this works because the object is converted to json and passed as the request body. Additionally, the contentType is defined as Json (APPLICATION_JSON_UTF8).

BOOST_PP_STRINGIZE seems a excellent solution for C++, but not for regular C.

Here is my solution for GNU CPP:

/* Some test definition here */
#define DEFINED_BUT_NO_VALUE
#define DEFINED_INT 3
#define DEFINED_STR "ABC"

/* definition to expand macro then apply to pragma message */
#define VALUE_TO_STRING(x) #x
#define VALUE(x) VALUE_TO_STRING(x)
#define VAR_NAME_VALUE(var) #var "="  VALUE(var)

/* Some example here */
#pragma message(VAR_NAME_VALUE(NOT_DEFINED))
#pragma message(VAR_NAME_VALUE(DEFINED_BUT_NO_VALUE))
#pragma message(VAR_NAME_VALUE(DEFINED_INT))
#pragma message(VAR_NAME_VALUE(DEFINED_STR))

Above definitions result in:

test.c:10:9: note: #pragma message: NOT_DEFINED=NOT_DEFINED
test.c:11:9: note: #pragma message: DEFINED_BUT_NO_VALUE=
test.c:12:9: note: #pragma message: DEFINED_INT=3
test.c:13:9: note: #pragma message: DEFINED_STR="ABC"

For "defined as interger", "defined as string", and "defined but no value" variables , they work just fine. Only for "not defined" variable, they displayed exactly the same as original variable name. You have to used to it -- or maybe someone can provide a better solution.

you are thinking too much... Take a look at this [i think this is what you wanted - if not let me know]

You can't.

In order to "use" the struct, i.e. to be able to declare objects of that type and to access its internals you need the full definition of the struct. So, it you want to do any of that (and you do, judging by your error messages), you have to place the full definition of the struct type into the header file.

I had to select from the information schema to get details of my tables and columns; in case it helps anyone:

SELECT * FROM information_schema.tables
WHERE table_schema = 'myschema'; 

SELECT * FROM information_schema.columns
WHERE table_schema = 'myschema' AND table_name = 'mytable'; 

Try

numbers = range(10, 16)
indices = (1, 1, 2, 1, 5)

result = [numbers[i] for i in indices]

To find all valid address list this is the code I have used

public static IEnumerable<string> GetAddresses()
{
      var host = Dns.GetHostEntry(Dns.GetHostName());
      return (from ip in host.AddressList where ip.AddressFamily == AddressFamily.lo select ip.ToString()).ToList();
}

You need to enclose your class in { and }. A few extra pointers: According to the Java coding conventions, you should

• Put your { on the same line as the method declaration:
• Name your classes using CamelCase (with initial capital letter)
• Name your methods using camelCase (with small initial letter)

Here's how I would write it:

public class ModMyMod extends BaseMod {

    public String version() {
         return "1.2_02";
    }

    public void addRecipes(CraftingManager recipes) {
       recipes.addRecipe(new ItemStack(Item.diamond), new Object[] {
          "#", Character.valueOf('#'), Block.dirt
       });
    }
}

We chose a combination of Mongo/Dynamo for a healthcare product. Basically mongo allows better searching, but the hosted Dynamo is great because its HIPAA compliant without any extra work. So we host the mongo portion with no personal data on a standard setup and allow amazon to deal with the HIPAA portion in terms of infrastructure. We can query certain items from mongo which bring up documents with pointers (ID's) of the relatable Dynamo document.

The main reason we chose to do this using mongo instead of hosting the entire application on dynamo was for 2 reasons. First, we needed to preform location based searches which mongo is great at and at the time, Dynamo was not, but they do have an option now.

Secondly was that some documents were unstructured and we did not know ahead of time what the data would be, so for example lets say user a inputs a document in the "form" collection like this: {"username": "user1", "email": "[email protected]"}. And another user puts this in the same collection {"phone": "813-555-3333", "location": [28.1234,-83.2342]}. With mongo we can search any of these dynamic and unknown fields at any time, with Dynamo, you could do this but would have to make a index every time a new field was added that you wanted searchable. So if you have never had a phone field in your Dynamo document before and then all of the sudden, some one adds it, its completely unsearchable.

Now this brings up another point in which you have mentioned. Sometimes choosing the right solution for the job does not always mean choosing the best product for the job. For example you may have a client who needs and will use the system you created for 10+ years. Going with a SaaS/IaaS solution that is good enough to get the job done may be a better option as you can rely on amazon to have up-kept and maintained their systems over the long haul.

Had this problem recently with converting nasty WMV into Final Cut Pro X for editing. Flow player can do it but it leaves a water mark, so I fiddled a bit with ffmpeg till I got something going.

First install ffmpeg - I used brew install ffmpeg Obviously you need brew installed first, google that bit.

Next I wrote a simple command line script with the following content - you can substitute the $1 for an input / output file or just create a shell script file... vi convert.sh Paste.

echo "Pass one" ffmpeg -y -i "$1" -c:v libx264 -preset medium -b:v 1555k -pass 1 -c:a libfaac -b:a 256k -f mp4 /dev/null && echo "Pass two" ffmpeg -i "$1" -c:v libx264 -preset medium -b:v 1555k -pass 2 -c:a libfaac -b:a 256k "$1.mp4"

Then to convert your video... sh convert.sh myvideofile.wmv If all went well you should see a new file called myvideofile.wmv.mp4.

Hope that works for you.

You can either

fig, ax = plt.subplots()  #create figure and axes
candlestick(ax, quotes, ...)

or

candlestick(plt.gca(), quotes) #get the axis when calling the function

The first gives you more flexibility. The second is much easier if candlestick is the only thing you want to plot

Easy one! "\t"

Edit: In fact, here's something official: Escape Sequences

From the link above:

Several of these types can be modified using the keywords signed, unsigned, short, and long. When one of these type modifiers is used by itself, a data type of int is assumed

This means that you can assume the author is using ints.

You can specify the version of Python for the driver by setting the appropriate environment variables in the ./conf/spark-env.sh file. If it doesn't already exist, you can use the spark-env.sh.template file provided which also includes lots of other variables.

Here is a simple example of a spark-env.sh file to set the relevant Python environment variables:

#!/usr/bin/env bash

# This file is sourced when running various Spark programs.
export PYSPARK_PYTHON=/usr/bin/python3       
export PYSPARK_DRIVER_PYTHON=/usr/bin/ipython

In this case it sets the version of Python used by the workers/executors to Python3 and the driver version of Python to iPython for a nicer shell to work in.

If you don't already have a spark-env.sh file, and don't need to set any other variables, this one should do what you want, assuming that paths to the relevant python binaries are correct (verify with which). I had a similar problem and this fixed it.

In mechanical terms a COMMIT makes a transaction. That is, a transaction is all the activity (one or more DML statements) which occurs between two COMMIT statements (or ROLLBACK).

In Oracle a DDL statement is a transaction in its own right simply because an implicit COMMIT is issued before the statement is executed and again afterwards. TRUNCATE is a DDL command so it doesn't need an explicit commit because calling it executes an implicit commit.

From a system design perspective a transaction is a business unit of work. It might consist of a single DML statement or several of them. It doesn't matter: only full transactions require COMMIT. It literally does not make sense to issue a COMMIT unless or until we have completed a whole business unit of work.

This is a key concept. COMMITs don't just release locks. In Oracle they also release latches, such as the Interested Transaction List. This has an impact because of Oracle's read consistency model. Exceptions such as ORA-01555: SNAPSHOT TOO OLD or ORA-01002: FETCH OUT OF SEQUENCE occur because of inappropriate commits. Consequently, it is crucial for our transactions to hang onto locks for as long as they need them.

Another ViewGroup:

A fragment is a ViewGroup which can be shown in an Activity. But it needs a Container. The container can be any Layout (FragmeLayout, LinearLayout, etc. It does not matter).

Step 1:

Define Activity Layout:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:layout_width="match_parent"
   android:layout_height="match_parent">
   <FrameLayout
       android:id="@+id/fragmentHolder"
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
    />
</RelativeLayout>

Step 2:

Define Fragment Layout:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical">
    <EditText
       android:id="@+id/user"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"/>
    <EditText
       android:id="@+id/password"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:inputType="textPassword"/>
    <Button
       android:id="@+id/login"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:text="Login"/>
</LinearLayout>

Step 3:

Create Fragment class

public class LoginFragment extends Fragment {


    private Button login;
    private EditText username, password;

    public static LoginFragment getInstance(String username){
       Bundle bundle = new Bundle();
       bundle.putInt("USERNAME", username);
       LoginFragment fragment = new LoginFragment();
       fragment.setArguments(bundle);
       return fragment;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup parent, Bundle savedInstanceState){
       View view = inflater.inflate(R.layout.login_fragment, parent, false);
       login = view.findViewById(R.id.login);
       username = view.findViewById(R.id.user);
       password = view.findViewById(R.id.password);
       String name = getArguments().getInt("USERNAME");
       username.setText(username);
       return view;
    }

}

Step 4:

Add fragment in Activity

public class ActivityB extends AppCompatActivity{

   private Fragment currentFragment;

   @Override
   protected void onCreate(Bundle savedInstanceState) {

       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_main);

       currentFragment = LoginFragment.getInstance("Rohit");
       getSupportFragmentManager()
                .beginTransaction()
                .add(R.id.fragmentHolder, currentFragment, "LOGIN_TAG")
                .commit();
   }

}

This is code is very basic. If you want to learn more advanced topics in Fragment then you can check out these resources:

Might sound stupid, But Params doesn't allow multidimensional array. Whereas you can pass a multidimensional array to a function.

Looks like Facebook disabled passing parameters to the sharer.

We have changed the behavior of the sharer plugin to be consistent with other plugins and features on our platform.

The sharer will no longer accept custom parameters and facebook will pull the information that is being displayed in the preview the same way that it would appear on facebook as a post from the url OG meta tags.

Here's the URL to the post: https://developers.facebook.com/x/bugs/357750474364812/

Extracting data from PDF is bound to be fraught with problems. Are the documents created through some kind of automatic process? If so, you might consider converting the PDFs to uncompressed PostScript (try pdf2ps) and seeing if the PostScript contains some sort of regular pattern which you can exploit.

Pyjnius.

Docs: http://pyjnius.readthedocs.org/en/latest/

Github: https://github.com/kivy/pyjnius

From the github page:

A Python module to access Java classes as Python classes using JNI.

PyJNIus is a "Work In Progress".

Quick overview

>>> from jnius import autoclass
>>> autoclass('java.lang.System').out.println('Hello world') Hello world

>>> Stack = autoclass('java.util.Stack')
>>> stack = Stack()
>>> stack.push('hello')
>>> stack.push('world')
>>> print stack.pop() world
>>> print stack.pop() hello

You can get this error if docker doesn't shut down cleanly. The following answer is for the docker snap package.

Run snap logs docker and look for the following:

Error starting daemon: pid file found, ensure docker is not running or delete /var/snap/docker/179/run/docker.pid

Deleting that file and restarting docker worked for me.

rm /var/snap/docker/<your-version-number>/run/docker.pid
snap stop docker
snap start docker

Make sure to replace ????<your-version-number>? with the appropriate version number.

I think this is cleaner:

import inspect
print inspect.stack()[0][1]

and gets the same information as:

print inspect.getfile(inspect.currentframe())

Where [0] is the current frame in the stack (top of stack) and [1] is for the file name, increase to go backwards in the stack i.e.

print inspect.stack()[1][1]

would be the file name of the script that called the current frame. Also, using [-1] will get you to the bottom of the stack, the original calling script.

*(myString.end() - 1) maybe? That's not exactly elegant either.

A python-esque myString.at(-1) would be asking too much of an already-bloated class.

To convert a string into a date, the easiest way AFAIK is the dateutil module:

import dateutil.parser
datetime_object = dateutil.parser.parse("2013-05-07")

It can also handle time zones:

print(dateutil.parser.parse("2013-05-07"))
>>> datetime.datetime(2013, 5, 7, 1, 12, 12, tzinfo=tzutc())

If you have a datetime object, say:

import pytz
import datetime
now = datetime.datetime.now(pytz.UTC)

and you want chop off the time part, then I think it is easier to construct a new object instead of "substracting the time part". It is shorter and more bullet proof:

date_part datetime.datetime(now.year, now.month, now.day, tzinfo=now.tzinfo)

It also keeps the time zone information, it is easier to read and understand than a timedelta substraction, and you also have the option to give a different time zone in the same step (which makes sense, since you will have zero time part anyway).

I do not have experience with version 7 of JBoss but with 5 I often had issues when redeploying apps which went away when I cleaned the work and tmp folder. I wrote a script for that which was executed everytime the server shut down. Maybe executing it before startup is better considering abnormal shutdowns (which weren't uncommon with Jboss 5 :))

bellow are cause above “org.xml.sax.SAXParseException: Content is not allowed in prolog” exception.

1. First check the file path of schema.xsd and file.xml.
2. The encoding in your XML and XSD (or DTD) should be same.
   XML file header: <?xml version='1.0' encoding='utf-8'?>
   XSD file header: <?xml version='1.0' encoding='utf-8'?>
3. if anything comes before the XML document type declaration.i.e: hello<?xml version='1.0' encoding='utf-16'?>

You can say:

sed -n '/ / p' filename    #there is a space between '//'

Use replace method of string like the following way:

String x="\"abcd";
String z=x.replace("\"", "");
System.out.println(z);

Output:

abcd

A simple safe way would be to use an alias. Place this into ~/.bashrc file: if you have gedit editor use

gedit ~/.bashrc

to go into the bashrc file and then at the top of the bashrc file make the following change.

alias python=python3

After adding the above in the file. run the below command

source ~/.bash_aliases or source ~/.bashrc

example:

$ python --version

Python 2.7.6

$ python3 --version

Python 3.4.3

$ alias python=python3

$ python --version

Python 3.4.3

Try http://support.microsoft.com/kb/207438 which will work for 2007 if you follow v12.0 in the registry.

You could either do:

x = raw_input("enter your name")
print "your name is %s " % x

or:

x = str(input("enter your name"))
print "your name is %s" % x

In my and possibly @BIOHAZARD case it was nginx proxy timeout. In default it's 60 sec without activity in socket

I changed it to 24h in nginx and it resolved problem

proxy_read_timeout 86400s;
proxy_send_timeout 86400s;

Something like this should do:

function cleanLocalStorage() {
    for(key in localStorage) {
        delete localStorage[key];
    }
}

Be careful about using this, though, as the user may have other data stored in localStorage and would probably be pretty ticked if you deleted that. I'd recommend either a) not storing the user's data in localStorage or b) storing the user's account stuff in a single variable, and then clearing that instead of deleting all the keys in localStorage.

Edit: As Lyn pointed out, you'll be good with localStorage.clear(). My previous points still stand, however.

In terms of networking and security, the Backend is by far the most (should be) secure node.

The middle-end portion, usually being a web server, will be somewhat in the wild and cut off in many respects from a company's network. The middle-end node is usually placed in the DMZ and segmented from the network with firewall settings. Most of the server-side code parsing of web pages is handled on the middle-end web server.

Getting to the backend means going through the middle-end, which has a carefully crafted set of rules allowing/disallowing access to the vital nummies which are stored on the database (backend) server.

As of 2020 and Jackson 2.10.1 there's no need for any special code, it's just a matter of telling Jackson what you want:

ObjectMapper objectMapper = new ObjectMapper();

// Register module that knows how to serialize java.time objects
// Provided by jackson-datatype-jsr310
objectMapper.registerModule(new JavaTimeModule());

// Ask Jackson to serialize dates as String (ISO-8601 by default)
objectMapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);

This has already been mentioned in this answer, I'm adding a unit test verifying the functionality:

import com.fasterxml.jackson.annotation.JsonFormat;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import com.fasterxml.jackson.datatype.jsr310.JavaTimeModule;
import lombok.Data;
import org.junit.jupiter.api.Test;

import java.time.LocalDate;

import static org.junit.jupiter.api.Assertions.assertEquals;

public class LocalDateSerializationTest {

    @Data
    static class TestBean {
        // Accept default ISO-8601 format
        LocalDate birthDate;
        // Use custom format
        @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "dd/MM/yyyy")
        LocalDate birthDateWithCustomFormat;
    }

    @Test
    void serializeDeserializeTest() throws JsonProcessingException {
        ObjectMapper objectMapper = new ObjectMapper();

        // Register module that knows how to serialize java.time objects
        objectMapper.registerModule(new JavaTimeModule());

        // Ask Jackson to serialize dates as String (ISO-8601 by default)
        objectMapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);

        // The JSON string after serialization
        String json = "{\"birthDate\":\"2000-01-02\",\"birthDateWithCustomFormat\":\"03/02/2001\"}";

        // The object after deserialization
        TestBean object = new TestBean();
        object.setBirthDate(LocalDate.of(2000, 1, 2));
        object.setBirthDateWithCustomFormat(LocalDate.of(2001, 2, 3));

        // Assert serialization
        assertEquals(json, objectMapper.writeValueAsString(object));

        // Assert deserialization
        assertEquals(object, objectMapper.readValue(json, TestBean.class));
    }
}

TestBean uses Lombok to generate the boilerplate for the bean.

From jQuery's website

Shorthand CSS properties (e.g. margin, background, border) are not supported. For example, if you want to retrieve the rendered margin, use: $(elem).css('marginTop') and $(elem).css('marginRight'), and so on.

You've shadowed the builtin set by accidentally using it as a variable name, here is a simple way to replicate your error

>>> set=set()
>>> set=set()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'set' object is not callable

The first line rebinds set to an instance of set. The second line is trying to call the instance which of course fails.

Here is a less confusing version using different names for each variable. Using a fresh interpreter

>>> a=set()
>>> b=a()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'set' object is not callable

Hopefully it is obvious that calling a is an error

Following is correct way:

xmlhttp.open("GET","getuser.php?fname="+abc ,true);

How to set redis password ?

step 2.enter command : sudo nano /etc/redis/redis.conf

step 3.find # requirepass foobared word and remove # and change foobared to YOUR PASSWORD

ex. requirepass root

This is the strict aliasing rule, found in section 3.10 of the C++03 standard (other answers provide good explanation, but none provided the rule itself):

If a program attempts to access the stored value of an object through an lvalue of other than one of the following types the behavior is undefined:

• the dynamic type of the object,
• a cv-qualified version of the dynamic type of the object,
• a type that is the signed or unsigned type corresponding to the dynamic type of the object,
• a type that is the signed or unsigned type corresponding to a cv-qualified version of the dynamic type of the object,
• an aggregate or union type that includes one of the aforementioned types among its members (including, recursively, a member of a subaggregate or contained union),
• a type that is a (possibly cv-qualified) base class type of the dynamic type of the object,
• a char or unsigned char type.

C++11 and C++14 wording (changes emphasized):

If a program attempts to access the stored value of an object through a glvalue of other than one of the following types the behavior is undefined:

• the dynamic type of the object,
• a cv-qualified version of the dynamic type of the object,
• a type similar (as defined in 4.4) to the dynamic type of the object,
• a type that is the signed or unsigned type corresponding to the dynamic type of the object,
• a type that is the signed or unsigned type corresponding to a cv-qualified version of the dynamic type of the object,
• an aggregate or union type that includes one of the aforementioned types among its elements or non-static data members (including, recursively, an element or non-static data member of a subaggregate or contained union),
• a type that is a (possibly cv-qualified) base class type of the dynamic type of the object,
• a char or unsigned char type.

Two changes were small: glvalue instead of lvalue, and clarification of the aggregate/union case.

The third change makes a stronger guarantee (relaxes the strong aliasing rule): The new concept of similar types that are now safe to alias.

Also the C wording (C99; ISO/IEC 9899:1999 6.5/7; the exact same wording is used in ISO/IEC 9899:2011 §6.5 ¶7):

An object shall have its stored value accessed only by an lvalue expression that has one of the following types ^{73) or 88)}:

• a type compatible with the effective type of the object,
• a quali?ed version of a type compatible with the effective type of the object,
• a type that is the signed or unsigned type corresponding to the effective type of the object,
• a type that is the signed or unsigned type corresponding to a quali?ed version of the effective type of the object,
• an aggregate or union type that includes one of the aforementioned types among its members (including, recursively, a member of a subaggregate or contained union), or
• a character type.

^{73) or 88)} The intent of this list is to specify those circumstances in which an object may or may not be aliased.

I have this problem when using STS. After edited something, I see that, some workspaces when create a project will happen this problem, and others will not. So I just create a new project in workspaces will not happen.

Just follows these steps:

1. Go to Control Panel ? Program and Feature.
2. Click on Turn Window Features on and off. A window opens.
3. Uncheck Hyper-V and Windows Hypervisor Platform options and restart your system.

Now, you can Start HAXM installation without any error.

I keep coming across this problem, so have written a script to download the self signed certificate from the server and install it to ~/.gitcerts, then update git-config to point to these certificates. It is stored in global config, so you only need to run it once per remote.

https://github.com/iwonbigbro/tools/blob/master/bin/git-remote-install-cert.sh

You can use the Bean Comparator to sort on any property in your custom class.

While createting the bat file, you can easly avoid the space. If you want to mentioned "program files "folder in batch file.

Do following steps:

1. Type c: then press enter

2. cd program files

3. cd "choose your own folder name"

then continue as you wish.

This way you can create batch file and you can mention program files folder.

JSTL 1.2 variation leveraged from BalusC answer

<c:set var="baseURL" value="${pageContext.request.requestURL.substring(0, pageContext.request.requestURL.length() - pageContext.request.requestURI.length())}${pageContext.request.contextPath}/" />

<head>
  <base href="${baseURL}" />

If you just want to see the current working directory

import os
print(os.getcwd())

If you want to change the current working directory

os.chdir(path)

path is a string containing the required path to be moved. e.g.

path = "C:\\Users\\xyz\\Desktop\\move here"

Centos 7 with PHP7.2:

sudo yum --enablerepo=remi-php72 install php-pecl-zip

Using JOIN makes the code easier to read, since it's self-explanatory.

There's no difference in speed(I have just tested it) and the execution plan is the same.

A simple tip: A simple space (or invisible special char) in your script, right before the very first <?php tag, can cause this ! Especially when you are working in a team and somebody is using a "weak" IDE or has messed around in the files with strange text editors.

I have seen these things ;)

Sublime Text -> Preferences -> Setting:

Write your style in right screen:

I haven't done time test with this but it was fun to try. Basically convert two columns to one column of tuples. Now convert that to a dataframe, do 'value_counts()' which finds the unique elements and counts them. Fiddle with zip again and put the columns in order you want. You can probably make the steps more elegant but working with tuples seems more natural to me for this problem

b = pd.DataFrame({'A':['yes','yes','yes','yes','no','no','yes','yes','yes','no'],'B':['yes','no','no','no','yes','yes','no','yes','yes','no']})

b['count'] = pd.Series(zip(*[b.A,b.B]))
df = pd.DataFrame(b['count'].value_counts().reset_index())
df['A'], df['B'] = zip(*df['index'])
df = df.drop(columns='index')[['A','B','count']]

Here is one possible solution to solve the problem without a library :

public static boolean delete(File file) {

    File[] flist = null;

    if(file == null){
        return false;
    }

    if (file.isFile()) {
        return file.delete();
    }

    if (!file.isDirectory()) {
        return false;
    }

    flist = file.listFiles();
    if (flist != null && flist.length > 0) {
        for (File f : flist) {
            if (!delete(f)) {
                return false;
            }
        }
    }

    return file.delete();
}

I recently wrote a gem to simplify this process and to neaten up your views, etc etc.

Another option would be to use the File Explorer in DDMS (Eclipse SDK), you can see the whole file system there and download/upload files to the desired place. That way you don't have to mount and deal with images. Just remember to set your device as USB debuggable (from Developer Tools)

For Unescape You can simply use this functions:

System.Text.RegularExpressions.Regex.Unescape(string)

System.Uri.UnescapeDataString(string)

I suggest using this method (It works better with UTF-8):

UnescapeDataString(string)

Also if you are looking for current file name along with the query string, you will just need following

basename($_SERVER['REQUEST_URI'])

It would provide you info like following example

file.php?arg1=val&arg2=val

And if you also want full path of file as well starting from root, e.g. /folder/folder2/file.php?arg1=val&arg2=val then just remove basename() function and just use fillowing

$_SERVER['REQUEST_URI']

I think you don't have to use sub query in this scenario.You can directly left outer join the DEPRMNT table .

While using Left Outer Join ,don't use columns in the RHS table of the join in the where condition, you ll get wrong output

Unfortunately I found solutions presented by @dualed have various flaws.

1. Using substr($sapi_type, 0, 3) == 'cgi' is not enogh to detect fast CGI. When using PHP-FPM FastCGI Process Manager, php_sapi_name() returns fpm not cgi

2. Fasctcgi and php-fpm expose another bug mentioned by @Josh - using header('X-PHP-Response-Code: 404', true, 404); does work properly under PHP-FPM (FastCGI)

3. header("HTTP/1.1 404 Not Found"); may fail when the protocol is not HTTP/1.1 (i.e. 'HTTP/1.0'). Current protocol must be detected using $_SERVER['SERVER_PROTOCOL'] (available since PHP 4.1.0

4. There are at least 2 cases when calling http_response_code() result in unexpected behaviour:

   • When PHP encounter an HTTP response code it does not understand, PHP will replace the code with one it knows from the same group. For example "521 Web server is down" is replaced by "500 Internal Server Error". Many other uncommon response codes from other groups 2xx, 3xx, 4xx are handled this way.
   • On a server with php-fpm and nginx http_response_code() function MAY change the code as expected but not the message. This may result in a strange "404 OK" header for example. This problem is also mentioned on PHP website by a user comment http://www.php.net/manual/en/function.http-response-code.php#112423

For your reference here there is the full list of HTTP response status codes (this list includes codes from IETF internet standards as well as other IETF RFCs. Many of them are NOT currently supported by PHP http_response_code function): http://en.wikipedia.org/wiki/List_of_HTTP_status_codes

You can easily test this bug by calling:

http_response_code(521);

The server will send "500 Internal Server Error" HTTP response code resulting in unexpected errors if you have for example a custom client application calling your server and expecting some additional HTTP codes.

My solution (for all PHP versions since 4.1.0):

$httpStatusCode = 521;
$httpStatusMsg  = 'Web server is down';
$phpSapiName    = substr(php_sapi_name(), 0, 3);
if ($phpSapiName == 'cgi' || $phpSapiName == 'fpm') {
    header('Status: '.$httpStatusCode.' '.$httpStatusMsg);
} else {
    $protocol = isset($_SERVER['SERVER_PROTOCOL']) ? $_SERVER['SERVER_PROTOCOL'] : 'HTTP/1.0';
    header($protocol.' '.$httpStatusCode.' '.$httpStatusMsg);
}

Conclusion

http_response_code() implementation does not support all HTTP response codes and may overwrite the specified HTTP response code with another one from the same group.

The new http_response_code() function does not solve all the problems involved but make things worst introducing new bugs.

The "compatibility" solution offered by @dualed does not work as expected, at least under PHP-FPM.

The other solutions offered by @dualed also have various bugs. Fast CGI detection does not handle PHP-FPM. Current protocol must be detected.

Any tests and comments are appreciated.

document.location.reload() stores the position, see in the docs.

Add additional true parameter to force reload, but without restoring the position.

document.location.reload(true)

MDN docs:

The forcedReload flag changes how some browsers handle the user's scroll position. Usually reload() restores the scroll position afterward, but forced mode can scroll back to the top of the page, as if window.scrollY === 0.

Try this command:

find / -name file.look

SELECT * FROM people WHERE email NOT LIKE '%_@__%.__%'

Anything more complex will likely return false negatives and run slower.

Validating e-mail addresses in code is virtually impossible.

There's certainly a performance difference when running a compiled script. If you run normal .py scripts, the machine compiles it every time it is run and this takes time. On modern machines this is hardly noticeable but as the script grows it may become more of an issue.

Png files can handle transparency. So you could use this question Save plot to image file instead of displaying it using Matplotlib so as to save you graph as a png file.

And if you want to turn all white pixel transparent, there's this other question : Using PIL to make all white pixels transparent?

If you want to turn an entire area to transparent, then there's this question: And then use the PIL library like in this question Python PIL: how to make area transparent in PNG? so as to make your graph transparent.

for i in ...:
    for j in ...:
        for k in ...:
            if something:
                # continue loop i

In a general case, when you have multiple levels of looping and break does not work for you (because you want to continue one of the upper loops, not the one right above the current one), you can do one of the following

Refactor the loops you want to escape from into a function

def inner():
    for j in ...:
        for k in ...:
            if something:
                return


for i in ...:
    inner()

The disadvantage is that you may need to pass to that new function some variables, which were previously in scope. You can either just pass them as parameters, make them instance variables on an object (create a new object just for this function, if it makes sense), or global variables, singletons, whatever (ehm, ehm).

Or you can define inner as a nested function and let it just capture what it needs (may be slower?)

for i in ...:
    def inner():
        for j in ...:
            for k in ...:
                if something:
                    return
    inner()

Use exceptions

Philosophically, this is what exceptions are for, breaking the program flow through the structured programming building blocks (if, for, while) when necessary.

The advantage is that you don't have to break the single piece of code into multiple parts. This is good if it is some kind of computation that you are designing while writing it in Python. Introducing abstractions at this early point may slow you down.

Bad thing with this approach is that interpreter/compiler authors usually assume that exceptions are exceptional and optimize for them accordingly.

class ContinueI(Exception):
    pass


continue_i = ContinueI()

for i in ...:
    try:
        for j in ...:
            for k in ...:
                if something:
                    raise continue_i
    except ContinueI:
        continue

Create a special exception class for this, so that you don't risk accidentally silencing some other exception.

Something else entirely

I am sure there are still other solutions.

Building from Ben's plugin this version handles select and you can pass an option to allowSubmit. ie. $("#form").enterAsTab({ 'allowSubmit': true}); This will allow enter to submit the form if the submit button is handling the event.

(function( $ ){
    $.fn.enterAsTab = function( options ) {  
    var settings = $.extend( {
       'allowSubmit': false
    }, options);
    this.find('input, select').live("keypress", {localSettings: settings}, function(event) {
        if (settings.allowSubmit) {
        var type = $(this).attr("type");
        if (type == "submit") {
            return true;
        } 
    }
    if (event.keyCode == 13 ) {
        var inputs =   $(this).parents("form").eq(0).find(":input:visible:not(disabled):not([readonly])");
        var idx = inputs.index(this);
        if (idx == inputs.length - 1) {
           idx = -1;
       } else {
           inputs[idx + 1].focus(); // handles submit buttons
      }
        try {
            inputs[idx + 1].select();
            }
        catch(err) {
            // handle objects not offering select
            }
        return false;
    }
});
  return this;
};
})( jQuery );

Here's a C# example I just cooked up, loosely based on the answer using CSS selectors, hopefully of use to others for seeing how to setup a ReadOnlyCollection of table rows and iterate over it in MS land at least. I'm looking through a collection of table rows to find a row with an OriginatorsRef (just a string) and a TD with an image that contains a title attribute with Overdue by in it:

    public ReadOnlyCollection<IWebElement> GetTableRows()
    {
        this.iwebElement = GetElement();
        return this.iwebElement.FindElements(By.CssSelector("tbody tr"));
    }

And within my main code:

        ...
        ReadOnlyCollection<IWebElement> TableRows;
        TableRows = f.Grid_Fault.GetTableRows();

        foreach (IWebElement row in TableRows)
        {
            if (row.Text.Contains(CustomTestContext.Current.OriginatorsRef) &&
              row.FindElements(By.CssSelector("td img[title*='Overdue by']")).Count > 0)
                return true;
        }

I would say in some cases it's ok to do nothing. Probably not something you should be doing by default, but in case there should be no way for the interrupt to happen, I'm not sure what else to do (probably logging error, but that does not affect program flow).

One case would be in case you have a task (blocking) queue. In case you have a daemon Thread handling these tasks and you do not interrupt the Thread by yourself (to my knowledge the jvm does not interrupt daemon threads on jvm shutdown), I see no way for the interrupt to happen, and therefore it could be just ignored. (I do know that a daemon thread may be killed by the jvm at any time and therefore are unsuitable in some cases).

EDIT: Another case might be guarded blocks, at least based on Oracle's tutorial at: http://docs.oracle.com/javase/tutorial/essential/concurrency/guardmeth.html

Netbeans needs to be able to index the maven repository. Allow it to do that and try again. It was giving me the same error and after it indexed the repository it ran like a charm

You can use sum to sum the elements of a list, however if your list is coming from raw_input, you probably want to convert the items to int or float first:

l = raw_input().split(' ')
sum(map(int, l))

You need to get the time when the application starts, and compare that to the time when the application ends.

Wen the app starts:

Calendar calendar = Calendar.getInstance();

// Get start time (this needs to be a global variable).
Date startDate = calendar.getTime();

When the application ends

Calendar calendar = Calendar.getInstance();

// Get start time (this needs to be a global variable).
Date endDate = calendar.getTime();

To get the difference (in millseconds), do this:

long sumDate = endDate.getTime() - startDate.getTime();

There is a std::swap in <algorithm>

If you are using alphine with docker, do this:

Setting the User Agent in PhantomJS

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
...
caps = DesiredCapabilities.PHANTOMJS
caps["phantomjs.page.settings.userAgent"] = "whatever you want"
driver = webdriver.PhantomJS(desired_capabilities=caps)

The only minor issue is that, unlike for Firefox and Chrome, this does not return your custom setting:

driver.execute_script("return navigator.userAgent")

So, if anyone figures out how to do that in PhantomJS, please edit my answer or add a comment below! Cheers.

From the term "automatic login" I suppose security (password protection) is not of key importance here.

The guidelines for solution could be to use a JavaScript bookmark (idea borrowed form a nice game published on M&M's DK site).

The idea is to create a javascript file and store it locally. It should do the login data entering depending on current site address. Just an example using jQuery:

// dont forget to include jQuery code
// preferably with .noConflict() in order not to break the site scripts
if (window.location.indexOf("mail.google.com") > -1) {
    // Lets login to Gmail
    jQuery("#Email").val("[email protected]");
    jQuery("#Passwd").val("superSecretPassowrd");
    jQuery("#gaia_loginform").submit();
}

Now save this as say login.js

Then create a bookmark (in any browser) with this (as an) url:

javascript:document.write("<script type='text/javascript' src='file:///path/to/login.js'></script>");

Now when you go to Gmail and click this bookmark you will get automatically logged in by your script.

Multiply the code blocks in your script, to add more sites in the similar manner. You could even combine it with window.open(...) functionality to open more sites, but that may get the script inclusion more complicated.

Note: This only illustrates an idea and needs lots of further work, it's not a complete solution.

Primary keys always need to be unique, foreign keys need to allow non-unique values if the table is a one-to-many relationship. It is perfectly fine to use a foreign key as the primary key if the table is connected by a one-to-one relationship, not a one-to-many relationship. If you want the same user record to have the possibility of having more than 1 related profile record, go with a separate primary key, otherwise stick with what you have.

If I'm not very much mistaken, you can use System.Network.whatever to check.

However, this will always incur a race condition.

The canonical way of checking is try to listen on that port. If you get an error that port wasn't open.

I think this is part of why bind() and listen() are two separate system calls.

String p1 = "example";
String p2 = "example";
String p3 = "example".intern();
String p4 = p2.intern();
String p5 = new String(p3);
String p6 = new String("example");
String p7 = p6.intern();

if (p1 == p2)
    System.out.println("p1 and p2 are the same");
if (p1 == p3)
    System.out.println("p1 and p3 are the same");
if (p1 == p4)
    System.out.println("p1 and p4 are the same");
if (p1 == p5)
    System.out.println("p1 and p5 are the same");
if (p1 == p6)
    System.out.println("p1 and p6 are the same");
if (p1 == p6.intern())
    System.out.println("p1 and p6 are the same when intern is used");
if (p1 == p7)
    System.out.println("p1 and p7 are the same");

When two strings are created independently, intern() allows you to compare them and also it helps you in creating a reference in the string pool if the reference didn't exist before.

When you use String s = new String(hi), java creates a new instance of the string, but when you use String s = "hi", java checks if there is an instance of word "hi" in the code or not and if it exists, it just returns the reference.

Since comparing strings is based on reference, intern() helps in you creating a reference and allows you to compare the contents of the strings.

When you use intern() in the code, it clears of the space used by the string referring to the same object and just returns the reference of the already existing same object in memory.

But in case of p5 when you are using:

String p5 = new String(p3);

Only contents of p3 are copied and p5 is created newly. So it is not interned.

So the output will be:

p1 and p2 are the same
p1 and p3 are the same
p1 and p4 are the same
p1 and p6 are the same when intern is used
p1 and p7 are the same

For #2 args will be only a formal parameter with dict value, but not a keyword type parameter.

If you want to pass a keyword type parameter into a keyword argument You need to specific ** before your dictionary, which means **args

It is not working. The PHP session will expire anyway after 1440 seconds.

Change in PHP.ini this too:

session.gc_maxlifetime = 3600

http://www.phpmyadmin.net/documentation/Documentation.html#config

Also, from PHP.ini:

If you are using the subdirectory option for storing session files

; (see session.save_path above), then garbage collection does not

; happen automatically. You will need to do your own garbage

; collection through a shell script, cron entry, or some other method.

; For example, the following script would is the equivalent of

; setting session.gc_maxlifetime to 1440 (1440 seconds = 24 minutes):

; cd /path/to/sessions; find -cmin +24 | xargs rm

Firstly run this query

SHOW VARIABLES LIKE '%char%';

You have character_set_server='latin1'

for eg if CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci replace it to CHARSET=latin1 and remove the collate

You are good to go

Thanks Ravi and other users .... Nevertheless I have got the solution

SELECT @phoneNumber=
CASE 
  WHEN  ISNULL(rdg2.nPhoneNumber  ,'0') in ('0','-',NULL)
THEN ISNULL(rdg2.nMobileNumber, '0') 
  WHEN ISNULL(rdg2.nMobileNumber, '0')  in ('0','-',NULL)
THEN '0'
  ELSE ISNULL(rdg2.nPhoneNumber  ,'0')
END 
FROM tblReservation_Details_Guest  rdg2 
WHERE nReservationID=@nReservationID

Just need to put '0' instead of 0

There are several issues:

1. elif option == 2: and the subsequent elif-else should be aligned with the second if option == 1, not with the for.

2. The for x in range(x, 1, 1): is missing a body.

3. Since "option 1 (count)" requires a second input, you need to call input() for the second time. However, for sanity's sake I urge you to store the result in a second variable rather than repurposing option.

4. The comparison in the first line of your code is probably meant to be an assignment.

You'll discover more issues once you're able to run your code (you'll need a couple more input() calls, one of the range() calls will need attention etc).

Lastly, please don't use the same variable as the loop variable and as part of the initial/terminal condition, as in:

            for x in range(1, x, 1):
                print x

It may work, but it is very confusing to read. Give the loop variable a different name:

            for i in range(1, x, 1):
                print i

Also, be careful so your href location isn't faulty. Study case:

My index page was in a temporary sub-folder named LAYOUTS. To reach the favicon.png from inside the IMAGES folder, which was a sibling of the LAYOUTS folder, I had to put a path in my href like this

href="../images/favicon-32x32.png"

Double periods are necessary for folder navigation "upwards", then the forward slash + images string gets you into the images folder (performing a tree branch "jump") and finally you get to reference your file by writing favicon-32x32.png.

This explanation is useful for those that start out from scratch and it would have been useful to have seen it a couple of times since I would forget that I had certain *.php files outside the LAYOUTS folder which needed different tree hrefs on my links, from the HEAD section of each page.

Reference the path to your favicon image accordingly.

for the sake of completeness, many solutions using sed or awk only translate a special set of characters and are hence quite large by code size and also dont translate other special characters that should be encoded.

a safe way to urlencode would be to just encode every single byte - even those that would've been allowed.

echo -ne 'some random\nbytes' | xxd -plain | tr -d '\n' | sed 's/\(..\)/%\1/g'

xxd is taking care here that the input is handled as bytes and not characters.

edit:

xxd comes with the vim-common package in Debian and I was just on a system where it was not installed and I didnt want to install it. The altornative is to use hexdump from the bsdmainutils package in Debian. According to the following graph, bsdmainutils and vim-common should have an about equal likelihood to be installed:

http://qa.debian.org/popcon-png.php?packages=vim-common%2Cbsdmainutils&show_installed=1&want_legend=1&want_ticks=1

but nevertheless here a version which uses hexdump instead of xxd and allows to avoid the tr call:

echo -ne 'some random\nbytes' | hexdump -v -e '/1 "%02x"' | sed 's/\(..\)/%\1/g'

This works for me across all mobile devices in both portrait and landscape modes.

assuming you have npm installed and bower installed globally

1. navigate to your project
2. bower init (this will generate the bower.json file in your directory)
3. (then keep clicking yes)...

4. to set the path where bootstrap will be installed:
   manually create a .bowerrc file next to the bower.json file and add the following to it:

   { "directory" : "public/components" }

5. bower install bootstrap --save

Note: to install other components:

 bower search {component-name-here}

I think the Wikipedia-article on Deprecation answers this one pretty well:

In the process of authoring computer software, its standards or documentation, deprecation is a status applied to software features to indicate that they should be avoided, typically because they have been superseded. Although deprecated features remain in the software, their use may raise warning messages recommending alternative practices, and deprecation may indicate that the feature will be removed in the future. Features are deprecated—rather than immediately removed—in order to provide backward compatibility, and give programmers who have used the feature time to bring their code into compliance with the new standard.

You could try this:

IWebElement dropDownListBox = driver.findElement(By.Id("selection"));
SelectElement clickThis = new SelectElement(dropDownListBox);
clickThis.SelectByText("Germany");

Maybe it is too late, but I am answering for future searches. TO perform spelling mistake correction, you first need to make sure the word is not absurd or from slang like, caaaar, amazzzing etc. with repeated alphabets. So, we first need to get rid of these alphabets. As we know in English language words usually have a maximum of 2 repeated alphabets, e.g., hello., so we remove the extra repetitions from the words first and then check them for spelling. For removing the extra alphabets, you can use Regular Expression module in Python.

Once this is done use Pyspellchecker library from Python for correcting spellings.

For implementation visit this link: https://rustyonrampage.github.io/text-mining/2017/11/28/spelling-correction-with-python-and-nltk.html

As rightly said in above answers, by calling flush() we force hibernate to execute the SQL commands on Database. But do understand that changes are not "committed" yet. So after doing flush and before doing commit, if you access DB directly (say from SQL prompt) and check the modified rows, you will NOT see the changes.

This is same as opening 2 SQL command sessions. And changes done in 1 session are not visible to others until committed.

you can find more information in spring context schema file. following is in spring-context-4.3.xsd

<conxtext:annotation-config />

Activates various annotations to be detected in bean classes: Spring's @Required and
@Autowired, as well as JSR 250's @PostConstruct, @PreDestroy and @Resource (if available),
JAX-WS's @WebServiceRef (if available), EJB 3's @EJB (if available), and JPA's
@PersistenceContext and @PersistenceUnit (if available). Alternatively, you may
choose to activate the individual BeanPostProcessors for those annotations.

Note: This tag does not activate processing of Spring's @Transactional or EJB 3's
@TransactionAttribute annotation. Consider the use of the <tx:annotation-driven>
tag for that purpose.

<context:component-scan>

Scans the classpath for annotated components that will be auto-registered as
Spring beans. By default, the Spring-provided @Component, @Repository, @Service, @Controller, @RestController, @ControllerAdvice, and @Configuration stereotypes    will be detected.

Note: This tag implies the effects of the 'annotation-config' tag, activating @Required,
@Autowired, @PostConstruct, @PreDestroy, @Resource, @PersistenceContext and @PersistenceUnit
annotations in the component classes, which is usually desired for autodetected components
(without external configuration). Turn off the 'annotation-config' attribute to deactivate
this default behavior, for example in order to use custom BeanPostProcessor definitions
for handling those annotations.

Note: You may use placeholders in package paths, but only resolved against system
properties (analogous to resource paths). A component scan results in new bean definitions
being registered; Spring's PropertySourcesPlaceholderConfigurer will apply to those bean
definitions just like to regular bean definitions, but it won't apply to the component
scan settings themselves.

These will print all lines from the last found line "TERMINATE" till end of file:

LINE_NUMBER=`grep -o -n TERMINATE $OSCAM_LOG|tail -n 1|sed "s/:/ \\'/g"|awk -F" " '{print $1}'`
tail -n +$LINE_NUMBER $YOUR_FILE_NAME

You can also do this.

//find the index of the CompanyName column
int columnIndex = thisReader.GetOrdinal("CompanyName"); 
//Get the value of the column. Will throw if the value is null.
string companyName = thisReader.GetString(columnIndex);

If a certificate expires in the middle of project debugging, you must do a manual uninstall:

Please execute adb uninstall <package_name> in a shell.

I assume that you can use the Oracle SQL Developer, which you can download from here.

You can define the date format which you want to work with:

ALTER SESSION SET nls_date_format='yyyy-mm-dd';

With this, now you can perform a query like this:

SELECT * FROM emp_company WHERE JDate = '2014-02-25'

If you want to be more specific you can define the date format like this:

ALTER SESSION SET nls_date_format='yyyy-mm-dd hh24:mi:ss';

try this, it work for me

Using plain java:

    String s = "1234567890";
    List<String> list = new Scanner(s).findAll("...").map(MatchResult::group).collect(Collectors.toList());
    System.out.printf("%s%n", list);

Produces the output:

[123, 456, 789]

Note that this discards leftover characters (0 in this case).

Another nice thing about @HostBinding is that you can combine it with @Input if your binding relies directly on an input, eg:

@HostBinding('class.fixed-thing')
@Input()
fixed: boolean;

Try using ports higher than 3000.

You need to install a so-called Instance of MSSQL server on your computer. That is, installing all the needed files and services and database files. By default, there should be no MSSQL Server installed on your machine, assuming that you use a desktop Windows (7,8,10...).

You can start off with Microsoft SQL Server Express, which is a 10GB-limited, free version of MSSQL. It also lacks some other features (Server Agents, AFAIR), but it's good for some experiments.

Download it from the Microsoft Website and go through the installer process by choosing New SQL Server stand-alone installation .. after running the installer.

Click through the steps. For your scenario (it sounds like you mainly want to test some stuff), the default options should suffice.

Just give attention to the step Instance Configuration. There you will set the name of your MSSQL Server Instance. Call it something unique/descriptive like MY_TEST_INSTANCE or the like. Also, choose wisely the Instance root directory. In it, the database files will be placed, so it should be on a drive that has enough space.

Click further through the wizard, and when it's finished, your MSSQL instance will be up and running. It will also run at every boot if you have chosen the default settings for the services.

As soon as it's running in the background, you can connect to it with Management Studio by connecting to .\MY_TEST_INSTANCE, given that that's the name you chose for the instance.

Use this function. Don't forget to save the WhatsApp Number on your mobile before sending trigger the function.

private void openWhatsApp() {
        Uri uri = Uri.parse("smsto:"+ "12345");
        Intent i = new Intent(Intent.ACTION_SENDTO,uri);
        i.setPackage("com.whatsapp");
        startActivity(i);
    }

use:

/^[ A-Za-z0-9_@./#&+-]*$/

You can also use the character class \w to replace A-Za-z0-9_

You can find a few examples here:

// Fill the DataSet.
DataSet ds = new DataSet();
ds.Locale = CultureInfo.InvariantCulture;
FillDataSet(ds);

DataTable contacts = ds.Tables["Contact"];
DataTable orders = ds.Tables["SalesOrderHeader"];

var query =
    contacts.AsEnumerable().Join(orders.AsEnumerable(),
    order => order.Field<Int32>("ContactID"),
    contact => contact.Field<Int32>("ContactID"),
    (contact, order) => new
    {
        ContactID = contact.Field<Int32>("ContactID"),
        SalesOrderID = order.Field<Int32>("SalesOrderID"),
        FirstName = contact.Field<string>("FirstName"),
        Lastname = contact.Field<string>("Lastname"),
        TotalDue = order.Field<decimal>("TotalDue")
    });


foreach (var contact_order in query)
{
    Console.WriteLine("ContactID: {0} "
                    + "SalesOrderID: {1} "
                    + "FirstName: {2} "
                    + "Lastname: {3} "
                    + "TotalDue: {4}",
        contact_order.ContactID,
        contact_order.SalesOrderID,
        contact_order.FirstName,
        contact_order.Lastname,
        contact_order.TotalDue);
}

Or just google for 'linq join method syntax'.

I always use this:

function validEmail($email){
    // First, we check that there's one @ symbol, and that the lengths are right
    if (!preg_match("/^[^@]{1,64}@[^@]{1,255}$/", $email)) {
        // Email invalid because wrong number of characters in one section, or wrong number of @ symbols.
        return false;
    }
    // Split it into sections to make life easier
    $email_array = explode("@", $email);
    $local_array = explode(".", $email_array[0]);
    for ($i = 0; $i < sizeof($local_array); $i++) {
        if (!preg_match("/^(([A-Za-z0-9!#$%&'*+\/=?^_`{|}~-][A-Za-z0-9!#$%&'*+\/=?^_`{|}~\.-]{0,63})|(\"[^(\\|\")]{0,62}\"))$/", $local_array[$i])) {
            return false;
        }
    }
    if (!preg_match("/^\[?[0-9\.]+\]?$/", $email_array[1])) { // Check if domain is IP. If not, it should be valid domain name
        $domain_array = explode(".", $email_array[1]);
        if (sizeof($domain_array) < 2) {
            return false; // Not enough parts to domain
        }
        for ($i = 0; $i < sizeof($domain_array); $i++) {
            if (!preg_match("/^(([A-Za-z0-9][A-Za-z0-9-]{0,61}[A-Za-z0-9])|([A-Za-z0-9]+))$/", $domain_array[$i])) {
                return false;
            }
        }
    }

    return true;
}

This is my solution:

1. Copy&paste $ANDROID_SDK/extras/android/support/v7/appcompat to your project ROOT

2. Open "Project Structure" on Intellij, click "Modules" on "Project Settings", then click "appcompat"->"android', make sure "Library Module" checkbox is checked.

3. click "YOUR-PROJECT_NAME" under "appcompat", remove "android-support-v4" and "android-support-v7-compat"; ensure the checkbox before "appcompat" is checked. And, click "ok" to close "Project Structure" dialogue.

4. back to the mainwindow, click "appcompat"->"libs" on the top-left project area. Right-click on "android-support-v4", select menuitem "Add as library", change "Add to Module" to "Your-project". Same with "android-support-v7-compat".

After doing above, intellij should be able to correctly find the android-support-XXXX modules.

Good Luck!

This answer by Jaap :

<div class="image"></div>?

and in CSS :

div.image {
   content:url(http://placehold.it/350x150);
}?

you can try it on this link : http://jsfiddle.net/XAh2d/

this is a link about css content http://css-tricks.com/css-content/

This has been tested on Chrome, firefox and Safari. (I'm on a mac, so if someone has the result on IE, tell me to add it)

Try this: overflow: auto;

It worked for my problem..

Use this if you want to see all the used and listening ports on a Windows server:

netstat -an |find /i "listening"

See all open, listening, established ports:

netstat -a

In my case, I have a file to import.
So I simply added SET sql_mode = ''; at the beginning of the file and it works!

Must check whether incoming access to port 3306 is block or not by the firewall.

$(window).load is an event that fires when the DOM and all the content (everything) on the page is fully loaded like CSS, images and frames. One best example is if we want to get the actual image size or to get the details of anything we use it.

$(document).ready() indicates that code in it need to be executed once the DOM got loaded and ready to be manipulated by script. It won't wait for the images to load for executing the jQuery script.

<script type = "text/javascript">
    //$(window).load was deprecated in 1.8, and removed in jquery 3.0
    // $(window).load(function() {
    //     alert("$(window).load fired");
    // });

    $(document).ready(function() {
        alert("$(document).ready fired");
    });
</script>

$(window).load fired after the $(document).ready().

$(document).ready(function(){

}) 
//and 
$(function(){

}); 
//and
jQuery(document).ready(function(){

});

Above 3 are same, $ is the alias name of jQuery, you may face conflict if any other JavaScript Frameworks uses the same dollar symbol $. If u face conflict jQuery team provide a solution no-conflict read more.

$(window).load was deprecated in 1.8, and removed in jquery 3.0

git pull and git rebase are not interchangeable, but they are closely connected.

git pull fetches the latest changes of the current branch from a remote and applies those changes to your local copy of the branch. Generally this is done by merging, i.e. the local changes are merged into the remote changes. So git pull is similar to git fetch & git merge.

Rebasing is an alternative to merging. Instead of creating a new commit that combines the two branches, it moves the commits of one of the branches on top of the other.

You can pull using rebase instead of merge (git pull --rebase). The local changes you made will be rebased on top of the remote changes, instead of being merged with the remote changes.

Atlassian has some excellent documentation on merging vs. rebasing.

You can also select your default terminal by pressing F1 in VS Code and typing/selecting Terminal: Select Default Shell.

As I was searching for Scala version, all I could find was McDowell's JNA code above. I include my Scala port here, as there currently isn't anywhere more appropriate.

import com.sun.jna.platform.win32._
object jna {
    def getHome: java.io.File = {
        if (!com.sun.jna.Platform.isWindows()) {
            new java.io.File(System.getProperty("user.home"))
        }
        else {
            val pszPath: Array[Char] = new Array[Char](WinDef.MAX_PATH)
            new java.io.File(Shell32.INSTANCE.SHGetSpecialFolderPath(null, pszPath, ShlObj.CSIDL_MYDOCUMENTS, false) match {
                case true => new String(pszPath.takeWhile(c => c != '\0'))
                case _    => System.getProperty("user.home")
            })
        }
    }
}

As with the Java version, you will need to add Java Native Access, including both jar files, to your referenced libraries.

It's nice to see that JNA now makes this much easier than when the original code was posted.

Yes you can do it using the JsonConvert.DeserializeObject. To do that, just simple do:

dynamic jsonResponse = JsonConvert.DeserializeObject(json);
Console.WriteLine(jsonResponse["message"]);

controlName.CssClass="CSS Class Name";

working example follows below

txtBank.CssClass = "csError";

Thread th = new Thread(function1);
th.Start();
th.Abort();

void function1(){
//code here
}

It would be more helpful if you posed a more complete working (or in this case non-working) example.

I tried the following:

import numpy as np
import matplotlib.pyplot as plt

x = np.random.randn(1000)

fig = plt.figure()
ax = fig.add_subplot(111)
n, bins, rectangles = ax.hist(x, 50, density=True)
fig.canvas.draw()
plt.show()

This will indeed produce a bar-chart histogram with a y-axis that goes from [0,1].

Further, as per the hist documentation (i.e. ax.hist? from ipython), I think the sum is fine too:

*normed*:
If *True*, the first element of the return tuple will
be the counts normalized to form a probability density, i.e.,
``n/(len(x)*dbin)``.  In a probability density, the integral of
the histogram should be 1; you can verify that with a
trapezoidal integration of the probability density function::

    pdf, bins, patches = ax.hist(...)
    print np.sum(pdf * np.diff(bins))

Giving this a try after the commands above:

np.sum(n * np.diff(bins))

I get a return value of 1.0 as expected. Remember that normed=True doesn't mean that the sum of the value at each bar will be unity, but rather than the integral over the bars is unity. In my case np.sum(n) returned approx 7.2767.

Regex provides much more flexibility.

    //document.location.href = "http://aaa.bbb.ccc.com/asdf/asdf/sadf.aspx?blah
    //1.
     var r = new RegExp(/http:\/\/[^/]+/);
     var match = r.exec(document.location.href) //gives http://aaa.bbb.ccc.com

    //2. 
     var r = new RegExp(/http:\/\/[^/]+\/[^/]+/);
     var match = r.exec(document.location.href) //gives http://aaa.bbb.ccc.com/asdf

I have a similar problem, and I remove the RuntimeFrameworkVersion, and the problem was fixed.

Try to remove 1.1.1 or

I wrote a tiny little function which does this. It only escapes ", &, < and > (but usually that's all you need anyway). It is slightly more elegant then the earlier proposed solutions in that it only uses one .replace() to do all the conversion. (EDIT 2: Reduced code complexity making the function even smaller and neater, if you're curious about the original code see end of this answer.)

function escapeHtml(text) {
    'use strict';
    return text.replace(/[\"&<>]/g, function (a) {
        return { '"': '&quot;', '&': '&amp;', '<': '&lt;', '>': '&gt;' }[a];
    });
}

This is plain Javascript, no jQuery used.

Escaping / and ' too

Edit in response to mklement's comment.

The above function can easily be expanded to include any character. To specify more characters to escape, simply insert them both in the character class in the regular expression (i.e. inside the /[...]/g) and as an entry in the chr object. (EDIT 2: Shortened this function too, in the same way.)

function escapeHtml(text) {
    'use strict';
    return text.replace(/[\"&'\/<>]/g, function (a) {
        return {
            '"': '&quot;', '&': '&amp;', "'": '&#39;',
            '/': '&#47;',  '<': '&lt;',  '>': '&gt;'
        }[a];
    });
}

Note the above use of ' for apostrophe (the symbolic entity ' might have been used instead – it is defined in XML, but was originally not included in the HTML spec and might therefore not be supported by all browsers. See: Wikipedia article on HTML character encodings). I also recall reading somewhere that using decimal entities is more widely supported than using hexadecimal, but I can't seem to find the source for that now though. (And there cannot be many browsers out there which does not support the hexadecimal entities.)

Note: Adding / and ' to the list of escaped characters isn't all that useful, since they do not have any special meaning in HTML and do not need to be escaped.

Original escapeHtml Function

EDIT 2: The original function used a variable (chr) to store the object needed for the .replace() callback. This variable also needed an extra anonymous function to scope it, making the function (needlessly) a little bit bigger and more complex.

var escapeHtml = (function () {
    'use strict';
    var chr = { '"': '&quot;', '&': '&amp;', '<': '&lt;', '>': '&gt;' };
    return function (text) {
        return text.replace(/[\"&<>]/g, function (a) { return chr[a]; });
    };
}());

I haven't tested which of the two versions are faster. If you do, feel free to add info and links about it here.

add this to you CSS:

html, body
{
    height: 100%;
}

working Fiddle

when you say to wrap to be 100%, 100% of what? of its parent (body), so his parent has to have some height.

and the same goes for body, his parent his html. html parent his the viewport.. so, by setting them both to 100%, wrap can also have a percentage height.

also: the elements have some default padding/margin, that causes them to span a little more then the height you applied to them. (causing a scroll bar) you can use

*
{
    padding: 0;
    margin: 0;
}

to disable that.

Look at That Fiddle

I work on normalize.css.

The main differences are:

1. Normalize.css preserves useful defaults rather than "unstyling" everything. For example, elements like sup or sub "just work" after including normalize.css (and are actually made more robust) whereas they are visually indistinguishable from normal text after including reset.css. So, normalize.css does not impose a visual starting point (homogeny) upon you. This may not be to everyone's taste. The best thing to do is experiment with both and see which gels with your preferences.

2. Normalize.css corrects some common bugs that are out of scope for reset.css. It has a wider scope than reset.css, and also provides bug fixes for common problems like: display settings for HTML5 elements, the lack of font inheritance by form elements, correcting font-size rendering for pre, SVG overflow in IE9, and the button styling bug in iOS.

3. Normalize.css doesn't clutter your dev tools. A common irritation when using reset.css is the large inheritance chain that is displayed in browser CSS debugging tools. This is not such an issue with normalize.css because of the targeted stylings.

4. Normalize.css is more modular. The project is broken down into relatively independent sections, making it easy for you to potentially remove sections (like the form normalizations) if you know they will never be needed by your website.

5. Normalize.css has better documentation. The normalize.css code is documented inline as well as more comprehensively in the GitHub Wiki. This means you can find out what each line of code is doing, why it was included, what the differences are between browsers, and more easily run your own tests. The project aims to help educate people on how browsers render elements by default, and make it easier for them to be involved in submitting improvements.

I've written in greater detail about this in an article about normalize.css

This class automatically polls the counter every 1 seconds and is also thread safe:

public class ProcessorUsage
{
    const float sampleFrequencyMillis = 1000;

    protected object syncLock = new object();
    protected PerformanceCounter counter;
    protected float lastSample;
    protected DateTime lastSampleTime;

    /// <summary>
    /// 
    /// </summary>
    public ProcessorUsage()
    {
        this.counter = new PerformanceCounter("Processor", "% Processor Time", "_Total", true);
    }

    /// <summary>
    /// 
    /// </summary>
    /// <returns></returns>
    public float GetCurrentValue()
    {
        if ((DateTime.UtcNow - lastSampleTime).TotalMilliseconds > sampleFrequencyMillis)
        {
            lock (syncLock)
            {
                if ((DateTime.UtcNow - lastSampleTime).TotalMilliseconds > sampleFrequencyMillis)
                {
                    lastSample = counter.NextValue();
                    lastSampleTime = DateTime.UtcNow;
                }
            }
        }

        return lastSample;
    }
}

I believe this error can also be thrown if your project is targeting a framework version that is not installed on the server you are deploying to.

First, you should place an UIButton and then either you can add a background image for this button, or you need to place an UIImageView over the button.

Or:

You can add the tap gesture to a UIImageView so that get the click action when tap on the UIImageView.

Output the images in a lossless format such as PNG:

ffmpeg.exe -i 10fps.h264 -r 10 -f image2 10fps.h264_%03d.png

Edit/Update: Not quite sure why I originally gave a strange filename example (with a possibly made-up extension).

I have since found that -vsync 0 is simpler than -r 10 because it avoids needing to know the frame rate.

This is something like what I currently use:

mkdir stills
ffmpeg -i my-film.mp4 -vsync 0 -f image2 stills/my-film-%06d.png

To extract only the key frames (which are likely to be of higher quality post-edit):

ffmpeg -skip_frame nokey -i my-film.mp4 -vsync 0 -f image2 stills/my-film-%06d.png

Then use another program (where you can more precisely specify quality, subsampling and DCT method – e.g. GIMP) to convert the PNGs you want to JPEG.

It is possible to obtain slightly sharper images in JPEG format this way than is possible with -qmin 1 -q:v 1 and outputting as JPEG directly from ffmpeg.

For Mac OS Mojave (10.14) Open terminal

$ sudo mkdir /usr/local/mysql-5.7.24-macos10.14-x86_64/etc
$ cd /usr/local/mysql-5.7.24-macos10.14-x86_64/etc
$ sudo nano my.cnf

Paste following:

[mysqld]
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION

Shortkeys to Save & Exit nano: Ctrl+x and y and Enter

Note: You might need to update mysql-5.7.24-macos10.14-x86_64 in these commands, just check the correct folder name you got within /usr/local/

Hope it will help someone!

In Ansible 2.x, you can use the block for group of tasks:

- block:
    - name: checkout repo
      git:
        repo: https://github.com/some/repo.git
        version: master
        dest: "{{ dst }}"
    - name: change perms
      file:
      dest: "{{ dst }}"
      state: directory
      mode: 0755
      owner: some_user
  become: yes
  become_user: some user

It can happen when server does not respond due to 100% CPU or Memory utilization.

I got this error when I was trying to access sonarqube API and the server was not responding due to full memory utilization

you can use function bellow in order to generate your UUID

create or replace FUNCTION RANDOM_GUID
    RETURN VARCHAR2 IS

    RNG    NUMBER;
    N      BINARY_INTEGER;
    CCS    VARCHAR2 (128);
    XSTR   VARCHAR2 (4000) := NULL;
  BEGIN
    CCS := '0123456789' || 'ABCDEF';
    RNG := 15;

    FOR I IN 1 .. 32 LOOP
      N := TRUNC (RNG * DBMS_RANDOM.VALUE) + 1;
      XSTR := XSTR || SUBSTR (CCS, N, 1);
    END LOOP;

    RETURN SUBSTR(XSTR, 1, 4) || '-' ||
        SUBSTR(XSTR, 5, 4)        || '-' ||
        SUBSTR(XSTR, 9, 4)        || '-' ||
        SUBSTR(XSTR, 13,4)        || '-' ||
        SUBSTR(XSTR, 17,4)        || '-' ||

        SUBSTR(XSTR, 24,4)        || '-' ||
        SUBSTR(XSTR, 28,4);
END RANDOM_GUID;

Example of GUID genedrated by the function above:
8EA4-196D-BC48-9793-8AE8-5500-03DC-9D04

You can cast it to

(<any>$('.selector') ).function();

Ex: date picker initialize using jquery

(<any>$('.datepicker') ).datepicker();

In owl carousel 2 you can use font-awesome icons or any custom images in navText option like this:

$(".category-wrapper").owlCarousel({
     items: 4,
     loop: true,
     margin: 30,
     nav: true,
     smartSpeed: 900,
     navText: ["<i class='fa fa-chevron-left'></i>","<i class='fa fa-chevron-right'></i>"]
});

As per different sources, I think the minimum length in E-164 format depends on country to country. For eg:

• For Israel: The minimum phone number length (excluding the country code) is 8 digits. - Official Source (Country Code 972)

• For Sweden : The minimum number length (excluding the country code) is 7 digits. - Official Source? (country code 46)

• For Solomon Islands its 5 for fixed line phones. - Source (country code 677)

... and so on. So including country code, the minimum length is 9 digits for Sweden and 11 for Israel and 8 for Solomon Islands.

Edit (Clean Solution): Actually, Instead of validating an international phone number by having different checks like length etc, you can use the Google's libphonenumber library. It can validate a phone number in E164 format directly. It will take into account everything and you don't even need to give the country if the number is in valid E164 format. Its pretty good! Taking an example:

String phoneNumberE164Format = "+14167129018"
PhoneNumberUtil phoneUtil = PhoneNumberUtil.getInstance();
try {
    PhoneNumber phoneNumberProto = phoneUtil.parse(phoneNumberE164Format, null);
    boolean isValid = phoneUtil.isValidNumber(phoneNumberProto); // returns true if valid
    if (isValid) {
        // Actions to perform if the number is valid
    } else {
        // Do necessary actions if its not valid 
    }
} catch (NumberParseException e) {
    System.err.println("NumberParseException was thrown: " + e.toString());
}

If you know the country for which you are validating the numbers, you don;t even need the E164 format and can specify the country in .parse function instead of passing null.

In Chart.js version 2.0, it is possible to set labels for axes:

options = {
  scales: {
    yAxes: [{
      scaleLabel: {
        display: true,
        labelString: 'probability'
      }
    }]
  }     
}

See Labelling documentation for more details.

In Windows 7, the MySQL database is stored at

C:\ProgramData\MySQL\MySQL Server 5.6\data

Note: this is a hidden folder. And my example is for MySQL Server version 5.6; change the folder name based on your version if different.

It comes in handy to know this location because sometimes the MySQL Workbench fails to drop schemas (or import databases). This is mostly due to the presence of files in the db folders that for some reason could not be removed in an earlier process by the Workbench. Remove the files using Windows Explorer and try again (dropping, importing), your problem should be solved.

Hope this helps :)

You need to set the Identity seed to that value:

CREATE TABLE orders
(
 id int IDENTITY(9586,1)
)

To alter an existing table:

ALTER TABLE orders ALTER COLUMN Id INT IDENTITY (9586, 1);

More info on CREATE TABLE (Transact-SQL) IDENTITY (Property)

++i is a pre-increment; i++ is post-increment.
The downside of post-increment is that it generates an extra value; it returns a copy of the old value while modifying i. Thus, you should avoid it when possible.

PNG has 2 advantages: it has smaller size and it's more widely used and supported (except in case favicons). As mentioned before ICO, can have multiple size icons, which is useful for desktop applications, but not too much for websites. I would recommend you to put a favicon.ico in the root of your application. An if you have access to the Head of your website pages use the tag to point to a png file. So older browser will show the favicon.ico and newer ones the png.

To create Png and Icon files I would recommend The Gimp.

This will do the trick:

If you can find the DB files... "cp DBFiles backup/"

Almost for sure not advisable in most cases, but it's simple as all getup.

On PyCharm Community or Professional Edition 2019.1+ :

1. From the menu bar click Run -> Edit Configurations
2. Add your arguments in the Parameters textbox (for example file2.txt file3.txt, or --myFlag myArg --anotherFlag mySecondArg)
3. Click Apply
4. Click OK

Make sure you click on Add python.exe to path during install, and select:

The best way is to build your script in a way it cannot create any errors! When there is something that can create a Notice or an Error there is something wrong with your script and the checking of variables and environment!

If you want to hide them anyway: error_reporting(0);

A view is a better approach but since hql typically returns a List or Set... you can do list_1.addAll(list_2). Totally sucks compared to a union but should work.

I believe it must work but any ways I'm not able to identify. Other approach can be,

<textarea (keyup)="emitWordCount(myModel)" [(ngModel)]="myModel"></textarea>


export class TextEditorComponent {
   @Output() countUpdate = new EventEmitter<number>();

   emitWordCount(model) {
       this.countUpdate.emit(
         (model.match(/\S+/g) || []).length);
       }
}

You can use sp_lock (and sp_lock2), but in SQL Server 2005 onwards this is being deprecated in favour of querying sys.dm_tran_locks:

select  
    object_name(p.object_id) as TableName, 
    resource_type, resource_description
from
    sys.dm_tran_locks l
    join sys.partitions p on l.resource_associated_entity_id = p.hobt_id

Excel 2010 - if you're looking to reorder the series on a pivot chart:

• go to your underlying pivot table
• right-click on one of the Column Labels for the series you're looking to adjust (Note: you need to click on one of the series headings (i.e. 'Saturday' or 'Sunday' in the example shown below) not the 'Column Labels' text itself)
• in the pop-up menu, hover over 'Move' and then select an option from the resulting sub-menu to reposition the series variable.
• your pivot chart will update itself accordingly

A keystore needs a keystore file. The KeyStore class needs a FileInputStream. But if you supply null (instead of FileInputStream instance) an empty keystore will be loaded. Once you create a keystore, you can verify its integrity using keytool.

Following code creates an empty keystore with empty password

  KeyStore ks2 = KeyStore.getInstance("jks");
  ks2.load(null,"".toCharArray());
  FileOutputStream out = new FileOutputStream("C:\\mykeytore.keystore");
  ks2.store(out, "".toCharArray());

Once you have the keystore, importing certificate is very easy. Checkout this link for the sample code.

I'm surprised no one had mentioned a simple function that takes a string and a list.

function in_list(needle, hay)
{
    var i, len;

    for (i = 0, len = hay.length; i < len; i++)
    {
        if (hay[i] == needle) { return true; }
    }

    return false;
}

var alist = ["test"];

console.log(in_list("test", alist));

A primitive quick fix that works.

If you only use OpenFileDialog, you can capture the FileName, SafeFileName, then subtract to get folder path:

exampleFileName = ofd.SafeFileName;
exampleFileNameFull = ofd.FileName;
exampleFileNameFolder = ofd.FileNameFull.Replace(ofd.FileName, "");

The d3.js visualization examples I've been replicating on my local machine.. which import .JSON data.. all work fine on Mozilla Firefox browser; and on Chrome I get the cross-origins restrictions error. It's a weird thing how there's no issue with importing a local javascript file, but try loading a JSON and the browser gets nervous. There should at least be some setting to let the user over-ride it, the way pop-ups are blocked but I get to see an indication and a choice to unblock them.. no reason to be so Orwellian about the matter. Users shouldn't be treated as too naive to know what's best for them.

So I suggest using Firefox browser if you're working locally. And I hope people don't freak out over this and start bombing Mozilla to enforce cross-origin restrictions for local files.

I have been using Inno Setup for an installer. I'm using 64-bit Windows 7 only. I'm finding that registry entries are being written to

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall

I haven't yet figured out how to get this list to be reported by WMI (although the program is listed as installed in Programs and Features). If I figure it out, I'll try to remember to report back here.

UPDATE:

Entries for 32-bit programs installed on a 64-bit machine go in that registry location. There's more written here:

http://mdb-blog.blogspot.com/2010/09/c-check-if-programapplication-is.html

See my comment that describes 32-bit vs 64-bit behavior in that same post here:

http://mdb-blog.blogspot.com/2010/09/c-check-if-programapplication-is.html?showComment=1300402090679#c861009270784046894

Unfortunately, there doesn't seem to be a way to get WMI to list all programs from the add/remove programs list (aka Programs and Features in Windows 7, not sure about Vista). My current code has dropped WMI in favor of using the registry. The code itself to interrogate the registry is even easier than using WMI. Sample code is in the above link.

private List<String[]> addresses = new ArrayList<String[]>();

this will work defenitely...

If you are using Angular UI Router, you can listen for the $viewContentLoadedevent.

"$viewContentLoaded - fired once the view is loaded, after the DOM is rendered. The '$scope' of the view emits the event." - Link

$scope.$on('$viewContentLoaded', 
function(event){ ... });

Use the command dir to list all the directories and files in a directory; ls is a unix command.

Next to being in the wrong directory I just tripped about another variant:

I had a File.open(my_file).each {|line| puts line} exploding but there was something by that name in the directory I was working in (ls in the command line showed the name). I checked with a File.exists?(my_file) which strangely returned false. Explanation: my_file was a symlink which target didn't exist anymore! Since File.exists? will follow a symlink it will say false though the link is still there.

Sounds like the "...and I jump line by line..." part is wrong. Do you StepOver or StepIn and are you sure you don't accidentally miss the relevant call?

That said, debugging frameworks can be tedious for exactly this reason. To alleviate the problem, you can enable the "Enable frameworks debugging support" experiment. Happy debugging! :)

If you're dealing with one or more classes which you can't change from the inside, there are generic and simple ways to do this that also don't depend on a diff-specific library:

Easiest, unsafe-for-very-complex-objects method

pickle.dumps(a) == pickle.dumps(b)

pickle is a very common serialization lib for Python objects, and will thus be able to serialize pretty much anything, really. In the above snippet I'm comparing the str from serialized a with the one from b. Unlike the next method, this one has the advantage of also type checking custom classes.

The biggest hassle: due to specific ordering and [de/en]coding methods, pickle may not yield the same result for equal objects, specially when dealing with more complex ones (e.g. lists of nested custom-class instances) like you'll frequently find in some third-party libs. For those cases, I'd recommend a different approach:

Thorough, safe-for-any-object method

You could write a recursive reflection that'll give you serializable objects, and then compare results

from collections.abc import Iterable

BASE_TYPES = [str, int, float, bool, type(None)]


def base_typed(obj):
    """Recursive reflection method to convert any object property into a comparable form.
    """
    T = type(obj)
    from_numpy = T.__module__ == 'numpy'

    if T in BASE_TYPES or callable(obj) or (from_numpy and not isinstance(T, Iterable)):
        return obj

    if isinstance(obj, Iterable):
        base_items = [base_typed(item) for item in obj]
        return base_items if from_numpy else T(base_items)

    d = obj if T is dict else obj.__dict__

    return {k: base_typed(v) for k, v in d.items()}


def deep_equals(*args):
    return all(base_typed(args[0]) == base_typed(other) for other in args[1:])

Now it doesn't matter what your objects are, deep equality is assured to work

>>> from sklearn.ensemble import RandomForestClassifier
>>>
>>> a = RandomForestClassifier(max_depth=2, random_state=42)
>>> b = RandomForestClassifier(max_depth=2, random_state=42)
>>> 
>>> deep_equals(a, b)
True

The number of comparables doesn't matter as well

>>> c = RandomForestClassifier(max_depth=2, random_state=1000)
>>> deep_equals(a, b, c)
False

My use case for this was checking deep equality among a diverse set of already trained Machine Learning models inside BDD tests. The models belonged to a diverse set of third-party libs. Certainly implementing __eq__ like other answers here suggest wasn't an option for me.

Covering all the bases

You may be in a scenario where one or more of the custom classes being compared do not have a __dict__ implementation. That's not common by any means, but it is the case of a subtype within sklearn's Random Forest classifier: <type 'sklearn.tree._tree.Tree'>. Treat these situations in a case by case basis - e.g. specifically, I decided to replace the content of the afflicted type with the content of a method that gives me representative information on the instance (in this case, the __getstate__ method). For such, the second-to-last row in base_typed became

d = obj if T is dict else obj.__dict__ if '__dict__' in dir(obj) else obj.__getstate__()

Edit: for the sake of organization, I replaced the hideous oneliner above with return dict_from(obj). Here, dict_from is a really generic reflection made to accommodate more obscure libs (I'm looking at you, Doc2Vec)

def isproperty(prop, obj):
    return not callable(getattr(obj, prop)) and not prop.startswith('_')


def dict_from(obj):
    """Converts dict-like objects into dicts
    """
    if isinstance(obj, dict):
        # Dict and subtypes are directly converted
        d = dict(obj)

    elif '__dict__' in dir(obj):
        # Use standard dict representation when available
        d = obj.__dict__

    elif str(type(obj)) == 'sklearn.tree._tree.Tree':
        # Replaces sklearn trees with their state metadata
        d = obj.__getstate__()

    else:
        # Extract non-callable, non-private attributes with reflection
        kv = [(p, getattr(obj, p)) for p in dir(obj) if isproperty(p, obj)]
        d = {k: v for k, v in kv}

    return {k: base_typed(v) for k, v in d.items()}

Do mind none of the above methods yield True for objects with the same key-value pairs in differing order, as in

>>> a = {'foo':[], 'bar':{}}
>>> b = {'bar':{}, 'foo':[]}
>>> pickle.dumps(a) == pickle.dumps(b)
False

But if you want that you could use Python's built-in sorted method beforehand anyway.

Please check if you have already close the database connection or not. In my case i was getting the error because the connection was close in upper line.

Use initial default values for all parameters like below

public string GetFindBooks(string author="", string title="", string isbn="", string  somethingelse="", DateTime? date= null) 
{
    // ...
}

Instead of doing all these, one can simply use ".Result" to get the result from a particular task.

eg: List list = GetListAsync().Result;

Which as per the definition => Gets the result value of this Task < TResult >

Ultimately, .keystore and .jks are just file extensions: it's up to you to name your files sensibly. Some application use a keystore file stored in $HOME/.keystore: it's usually implied that it's a JKS file, since JKS is the default keystore type in the Sun/Oracle Java security provider. Not everyone uses the .jks extension for JKS files, because it's implied as the default. I'd recommend using the extension, just to remember which type to specify (if you need).

In Java, the word keystore can have either of the following meanings, depending on the context:

• the API: http://docs.oracle.com/javase/6/docs/api/java/security/KeyStore.html
• a file (or other mechanism) that can be used to back this API
• a keystore as opposed to a truststore, as described here: https://stackoverflow.com/a/6341566/372643

When talking about the file and storage, this is not really a storage facility for key/value pairs (there are plenty or other formats for this). Rather, it's a container to store cryptographic keys and certificates (I believe some of them can also store passwords). Generally, these files are encrypted and password-protected so as not to let this data available to unauthorized parties.

Java uses its KeyStore class and related API to make use of a keystore (whether it's file based or not). JKS is a Java-specific file format, but the API can also be used with other file types, typically PKCS#12. When you want to load a keystore, you must specify its keystore type. The conventional extensions would be:

• .jks for type "JKS",
• .p12 or .pfx for type "PKCS12" (the specification name is PKCS#12, but the # is not used in the Java keystore type name).

In addition, BouncyCastle also provides its implementations, in particular BKS (typically using the .bks extension), which is frequently used for Android applications.

HTML:

<div id="something">... content ...</div>

CSS:

#something {
    position: absolute;
    height: 200px;
    width: 400px;
    margin: -100px 0 0 -200px;
    top: 50%;
    left: 50%;
}

You can use parameter from reCaptcha. By default it uses normal value on data-size, You just have to use compact to fit this on small devices or some-kind small width layouts.

example:

<div class="g-recaptcha" data-size="compact"></div>

You can use the default traceroute command for this purpose, then there will be nothing to install.

traceroute -T -p 9100 <IP address/hostname>

The -T argument is required so that the TCP protocol is used instead of UDP.

In the rare case when traceroute isn't available, you can also use ncat.

nc -Czvw 5 <IP address/hostname> 9100

All those settings are necessary to choose which tags you are interested in, but in order to display these tags in a list, you also need to select the right Eclipse perspective. I finally discovered that the "Markers" tab containing the "Task" list is only available under the "Java EE" perspective... Hope this helps! :-)

In case you prefer to use jQuery to set the image from Base64:

$("#img").attr('src', 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==');

Download and install LINQPad, it works for SQL Server, MySQL, SQLite and also SDF (SQL CE 4.0).

Steps for open SDF Files:

1. Click Add Connection

2. Select Build data context automatically and Default (LINQ to SQL), then Next.

3. Under Provider choose SQL CE 4.0.

4. Under Database with Attach database file selected, choose Browse to select your .sdf file.

5. Click OK.

You forgot to put z as an bind variable.

The following EXECUTE command runs a PL/SQL statement that references a stored procedure:

SQL> EXECUTE -
> :Z := EMP_SALE.HIRE('JACK','MANAGER','JONES',2990,'SALES')

Note that the value returned by the stored procedure is being return into :Z

There is another simple solution found there: http://www.r-bloggers.com/converting-a-string-to-a-variable-name-on-the-fly-and-vice-versa-in-r/

To convert a string to a variable:

x <- 42
eval(parse(text = "x"))
[1] 42

And the opposite:

x <- 42
deparse(substitute(x))
[1] "x"

The fastest way, to get a hash string for password store purposes, is a following code:

    internal static string GetStringSha256Hash(string text)
    {
        if (String.IsNullOrEmpty(text))
            return String.Empty;

        using (var sha = new System.Security.Cryptography.SHA256Managed())
        {
            byte[] textData = System.Text.Encoding.UTF8.GetBytes(text);
            byte[] hash = sha.ComputeHash(textData);
            return BitConverter.ToString(hash).Replace("-", String.Empty);
        }
    }

Remarks:

• if the method is invoked often, the creation of sha variable should be refactored into a class field;
• output is presented as encoded hex string;

You need to make your regular expression non-greedy, because by default, "(.*)" will match all of "file path/level1/level2" xxx some="xxx".

Instead you can make your dot-star non-greedy, which will make it match as few characters as possible:

/location="(.*?)"/

Adding a ? on a quantifier (?, * or +) makes it non-greedy.
