This question has been asked many times on this site and the definitive answer is: NO, you can't connect an Android phone to an iPhone over Bluetooth, and YES Apple has restrictions that prevent this.

Some possible alternatives:

1. Bonjour over WiFi, as you mentioned. However, I couldn't find a comprehensive tutorial for it.
2. Some internet based sync service, like Dropbox, Google Drive, Amazon S3. These usually have libraries for several platforms.
3. Direct TCP/IP communication over sockets. (How to write a small (socket) server in iOS)
4. Bluetooth Low Energy will be possible once the issues on the Android side are solved (Communicating between iOS and Android with Bluetooth LE)

Coolest alternative: use the Bump API. It has iOS and Android support and really easy to integrate. For small payloads this can be the most convenient solution.

Details on why you can't connect an arbitrary device to the iPhone. iOS allows only some bluetooth profiles to be used without the Made For iPhone (MFi) certification (HPF, A2DP, MAP...). The Serial Port Profile that you would require to implement the communication is bound to MFi membership. Membership to this program provides you to the MFi authentication module that has to be added to your hardware and takes care of authenticating the device towards the iPhone. Android phones don't have this module, so even though the physical connection may be possible to build up, the authentication step will fail. iPhone to iPhone communication is possible as both ends are able to authenticate themselves.

As another variation on Totem's known type solution, you can use reflection to create a generic type resolver to avoid the need to use known type attributes.

This uses a technique similar to Juval Lowy's GenericResolver for WCF.

As long as your base class is abstract or an interface, the known types will be automatically determined rather than having to be decorated with known type attributes.

In my own case I opted to use a $type property to designate type in my json object rather than try to determine it from the properties, though you could borrow from other solutions here to use property based determination.

 public class JsonKnownTypeConverter : JsonConverter
{
    public IEnumerable<Type> KnownTypes { get; set; }

    public JsonKnownTypeConverter() : this(ReflectTypes())
    {

    }
    public JsonKnownTypeConverter(IEnumerable<Type> knownTypes)
    {
        KnownTypes = knownTypes;
    }

    protected object Create(Type objectType, JObject jObject)
    {
        if (jObject["$type"] != null)
        {
            string typeName = jObject["$type"].ToString();
            return Activator.CreateInstance(KnownTypes.First(x => typeName == x.Name));
        }
        else
        {
            return Activator.CreateInstance(objectType);
        }
        throw new InvalidOperationException("No supported type");
    }

    public override bool CanConvert(Type objectType)
    {
        if (KnownTypes == null)
            return false;

        return (objectType.IsInterface || objectType.IsAbstract) && KnownTypes.Any(objectType.IsAssignableFrom);
    }

    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
    {
        // Load JObject from stream
        JObject jObject = JObject.Load(reader);

        // Create target object based on JObject
        var target = Create(objectType, jObject);
        // Populate the object properties
        serializer.Populate(jObject.CreateReader(), target);
        return target;
    }

    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
    {
        throw new NotImplementedException();
    }

    //Static helpers
    static Assembly CallingAssembly = Assembly.GetCallingAssembly();

    static Type[] ReflectTypes()
    {
        List<Type> types = new List<Type>();
        var referencedAssemblies = Assembly.GetExecutingAssembly().GetReferencedAssemblies();
        foreach (var assemblyName in referencedAssemblies)
        {
            Assembly assembly = Assembly.Load(assemblyName);
            Type[] typesInReferencedAssembly = GetTypes(assembly);
            types.AddRange(typesInReferencedAssembly);
        }

        return types.ToArray();
    }

    static Type[] GetTypes(Assembly assembly, bool publicOnly = true)
    {
        Type[] allTypes = assembly.GetTypes();

        List<Type> types = new List<Type>();

        foreach (Type type in allTypes)
        {
            if (type.IsEnum == false &&
               type.IsInterface == false &&
               type.IsGenericTypeDefinition == false)
            {
                if (publicOnly == true && type.IsPublic == false)
                {
                    if (type.IsNested == false)
                    {
                        continue;
                    }
                    if (type.IsNestedPrivate == true)
                    {
                        continue;
                    }
                }
                types.Add(type);
            }
        }
        return types.ToArray();
    }

It can then be installed as a formatter

GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.Converters.Add(new JsonKnownTypeConverter());

jQuery will do the job. You can use either jQuery.ajax function, which is general one for performing ajax calls, or its wrappers: jQuery.get, jQuery.post for getting/posting data. Its very easy to use, for example, check out this tutorial, which shows how to use jQuery with PHP.

Recently I learned of the following syntax:

DELETE (SELECT *
        FROM productfilters pf
        INNER JOIN product pr
            ON pf.productid = pr.id
        WHERE pf.id >= 200
            AND pr.NAME = 'MARK')

I think it looks much cleaner then other proposed code.

One of the main reason for this error is due to permission not granted to all users. so remove this error, follow the following steps :
1) Go to the C:/Programme Files/Apache Software Foundation/Tomcat 7.0
2) Right click on the Tomcat 7.0 folder and click on properties.
3) go to Security Tab.
4) Select the User and click on Edit... button
5) Grant all the permission to the user and click on apply and ok.
Refresh the system and now try. I hope it will work

In my case, the command that best suited me was:

jupyter nbconvert --execute --clear-output <notebook>.ipynb

Why? This command does not create extra files (just like a .py file) and the output of the cells is overwritten everytime the notebook is executed.

If you run:

jupyter nbconvert --help

--clear-output Clear output of current file and save in place, overwriting the existing notebook.

Using standard java libs, I suggest looking at the HttpUrlConnection class http://java.sun.com/javase/6/docs/api/java/net/HttpURLConnection.html

It can handle most of what curl can do with setting up the connection. What you do with the stream is up to you.

Without XML Schema (XSD file) an XML file is a relatively free set of elements and attributes. The XSD file defines which elements and attributes are permitted and in which order.

In general XML is a metalanguage. XSD files define specific languages within that metalanguage. For example, if your XSD file contains the definition of XHTML 1.0, then your XML file is required to fit XHTML 1.0 rather than some other format.

For the MySQL fans out there, I like the IFNULL() function. Other answers here suggest similar functionality with the ISNULL() function in some implementations. In my situation, I have a column of descriptions which is NOT NULL, and a column of serial numbers which may be NULL This is how I combined them into one column:

SELECT CONCAT(description,IFNULL(' SN: ', serial_number),'')) FROM my_table;

My results suggest that the results of concatenating a string with NULL results in a NULL. I have been getting the alternative value in those cases.

I've just created an android library, that allows you to easily modify the button color and the ripple color

https://github.com/xgc1986/RippleButton

<com.xgc1986.ripplebutton.widget.RippleButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/btn"
    android:text="Android button modified in layout"
    android:textColor="@android:color/white"
    app:buttonColor="@android:color/black"
    app:rippleColor="@android:color/white"/>

You don't need to create an style for every button you want wit a different color, allowing you to customize the colors randomly

This may seem slightly off topic but this was the post I came across when wondering what happens when you read a column as a dateTime in c#. The post reflects the information I would have liked to be able to find about this mechanism. If you worry about utc and timezones then read on

I did a little more research as I'm always very wary of DateTime as a class because of its automatic assumptions about what timezone you are using and because it is way too easy to confuse local times and utc times.

What I'm trying to avoid here is DateTime going 'oh look the computer I'm being run on is in timezone x, therefore this time must also be in timezone x, when I get asked for my values I'll reply as if I'm in that timezone'

I was trying to read a datetime2 column.

The date time you will get back from sql server will end up being of Kind.Unspecified this seems to mean it gets treated like UTC, which is what I wanted.

When reading a date column you also have to read it as a DateTime even though it has no time and is even more prone to screwing up by timezones (as it is on midnight).

I'd certainly consider this to be safer way of reading the DateTime as I suspect it can probably be modified by either settings in sql server or static settings in your c#:

var time = reader.GetDateTime(1);
var utcTime = new DateTime(time.Ticks, DateTimeKind.Utc);

From there you can get the components (Day, Month, Year) etc and format how you like.

If what you have is actually a date + a time then Utc might not be what you want there - since you are mucking around on the client you may need to convert it to a local time first (depending on what the meaning of the time is). However that opens up a whole can of worms.. If you need to do that I'd recommend using a library like noda time. There is TimeZoneInfo in the standard library but after briefly investigating it, it doesn't seem to have a proper set of timezones. You can see the list provided by TimeZoneInfo by using the method TimeZoneInfo.GetSystemTimeZones();

I also discovered sql server management studio doesn't convert times to local time before displaying them. Which is a relief!

var baseTags = document.getElementsByTagName("base");
var basePath = baseTags.length ? 
    baseTags[ 0 ].href.substr( location.origin.length, 999 ) : 
    "";

As this is the top post if you google for MySQL high CPU usage or load, I'll add an additional answer:

On the 1st of July 2012, a leap second was added to the current UTC-time to compensate for the slowing rotation of the earth due to the tides. When running ntp (or ntpd) this second was added to your computer's/server's clock. MySQLd does not seem to like this extra second on some OS'es, and yields a high CPU load. The quick fix is (as root):

$ /etc/init.d/ntpd stop
$ date -s "`date`"
$ /etc/init.d/ntpd start

• db:migrate runs (single) migrations that have not run yet.

• db:create creates the database

• db:drop deletes the database

• db:schema:load creates tables and columns within the existing database following schema.rb. This will delete existing data.

• db:setup does db:create, db:schema:load, db:seed

• db:reset does db:drop, db:setup

• db:migrate:reset does db:drop, db:create, db:migrate

Typically, you would use db:migrate after having made changes to the schema via new migration files (this makes sense only if there is already data in the database). db:schema:load is used when you setup a new instance of your app.

I hope that helps.

UPDATE for rails 3.2.12:

I just checked the source and the dependencies are like this now:

• db:create creates the database for the current env

• db:create:all creates the databases for all envs

• db:drop drops the database for the current env

• db:drop:all drops the databases for all envs

• db:migrate runs migrations for the current env that have not run yet

• db:migrate:up runs one specific migration

• db:migrate:down rolls back one specific migration

• db:migrate:status shows current migration status

• db:rollback rolls back the last migration

• db:forward advances the current schema version to the next one

• db:seed (only) runs the db/seed.rb file

• db:schema:load loads the schema into the current env's database

• db:schema:dump dumps the current env's schema (and seems to create the db as well)

• db:setup runs db:schema:load, db:seed

• db:reset runs db:drop db:setup

• db:migrate:redo runs (db:migrate:down db:migrate:up) or (db:rollback db:migrate) depending on the specified migration

• db:migrate:reset runs db:drop db:create db:migrate

For further information please have a look at https://github.com/rails/rails/blob/v3.2.12/activerecord/lib/active_record/railties/databases.rake (for Rails 3.2.x) and https://github.com/rails/rails/blob/v4.0.5/activerecord/lib/active_record/railties/databases.rake (for Rails 4.0.x)

Replace

values = ",".join(value_list)

with

values = ','.join([str(i) for i in value_list])

OR

values = ','.join(str(value_list)[1:-1])

You can find where the my.cnf file has been provided by the specific package, e.g.

brew list mysql # or: mariadb

In addition to verify if that file is read, you can run:

sudo fs_usage | grep my.cnf

which will show you filesystem activity in real-time related to that file.

This has been really helpful. Here is my implementation for any given table:

def sql_replace(self, tableobject, dictargs):

    #missing check of table object is valid
    primarykeys = [key.name for key in inspect(tableobject).primary_key]

    filterargs = []
    for primkeys in primarykeys:
        if dictargs[primkeys] is not None:
            filterargs.append(getattr(db.RT_eqmtvsdata, primkeys) == dictargs[primkeys])
        else:
            return

    query = select([db.RT_eqmtvsdata]).where(and_(*filterargs))

    if self.r_ExecuteAndErrorChk2(query)[primarykeys[0]] is not None:
        # update
        filter = and_(*filterargs)
        query = tableobject.__table__.update().values(dictargs).where(filter)
        return self.w_ExecuteAndErrorChk2(query)

    else:
        query = tableobject.__table__.insert().values(dictargs)
        return self.w_ExecuteAndErrorChk2(query)

# example usage
inrow = {'eqmtvs_id': eqmtvsid, 'datetime': dtime, 'param_id': paramid}

self.sql_replace(tableobject=db.RT_eqmtvsdata, dictargs=inrow)

Tagging of the image isn't supported inside the Dockerfile. This needs to be done in your build command. As a workaround, you can do the build with a docker-compose.yml that identifies the target image name and then run a docker-compose build. A sample docker-compose.yml would look like

version: '2'

services:
  man:
    build: .
    image: dude/man:v2

That said, there's a push against doing the build with compose since that doesn't work with swarm mode deploys. So you're back to running the command as you've given in your question:

docker build -t dude/man:v2 .

Personally, I tend to build with a small shell script in my folder (build.sh) which passes any args and includes the name of the image there to save typing. And for production, the build is handled by a ci/cd server that has the image name inside the pipeline script.

Had the same error: java.lang.RuntimeException: Unable to instantiate activity (classnotfound) FIRST try to change the build platform (2.3.3 -> 2.2 -> 2.3.3) worked for me.

Try ZZ to save and close. Here is a bit more info on using vim with Git

You can try: .order_by(ClientTotal.id.desc())

session = Session()
auth_client_name = 'client3' 
result_by_auth_client = session.query(ClientTotal).filter(ClientTotal.client ==
auth_client_name).order_by(ClientTotal.id.desc()).all()

for rbac in result_by_auth_client:
    print(rbac.id) 
session.close()

Add the UTC offset to the local time then convert it to the desired format with the toLocaleDateString() method of the Date object:

// Using the current date/time
let now_local = new Date();
let now_utc = new Date();

// Adding the UTC offset to create the UTC date/time
now_utc.setMinutes(now_utc.getMinutes() + now_utc.getTimezoneOffset())

// Specify the format you want
let date_format = {};
date_format.year = 'numeric';
date_format.month = 'numeric';
date_format.day = '2-digit';
date_format.hour = 'numeric';
date_format.minute = 'numeric';
date_format.second = 'numeric';

// Printing the date/time in UTC then local format
console.log('Date in UTC: ', now_utc.toLocaleDateString('us-EN', date_format));
console.log('Date in LOC: ', now_local.toLocaleDateString('us-EN', date_format));

I'm creating a date object defaulting to the local time. I'm adding the UTC off-set to it. I'm creating a date-formatting object. I'm displaying the UTC date/time in the desired format:

You can work around this by creating a separate VIEW for any subquery you want to use and then join to that in the VIEW you're creating. Here's an example: http://blog.gruffdavies.com/2015/01/25/a-neat-mysql-hack-to-create-a-view-with-subquery-in-the-from-clause/

This is quite handy as you'll very likely want to reuse it anyway and helps you keep your SQL DRY.

Use following meta tag in your html header file, This works for me.

Can you use default android Crop functionality?

Here is my code

private void performCrop(Uri picUri) {
    try {
        Intent cropIntent = new Intent("com.android.camera.action.CROP");
        // indicate image type and Uri
        cropIntent.setDataAndType(picUri, "image/*");
        // set crop properties here
        cropIntent.putExtra("crop", true);
        // indicate aspect of desired crop
        cropIntent.putExtra("aspectX", 1);
        cropIntent.putExtra("aspectY", 1);
        // indicate output X and Y
        cropIntent.putExtra("outputX", 128);
        cropIntent.putExtra("outputY", 128);
        // retrieve data on return
        cropIntent.putExtra("return-data", true);
        // start the activity - we handle returning in onActivityResult
        startActivityForResult(cropIntent, PIC_CROP);
    }
    // respond to users whose devices do not support the crop action
    catch (ActivityNotFoundException anfe) {
        // display an error message
        String errorMessage = "Whoops - your device doesn't support the crop action!";
        Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT);
        toast.show();
    }
}

declare:

final int PIC_CROP = 1;

at top.

In onActivity result method, writ following code:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == PIC_CROP) {
        if (data != null) {
            // get the returned data
            Bundle extras = data.getExtras();
            // get the cropped bitmap
            Bitmap selectedBitmap = extras.getParcelable("data");

            imgView.setImageBitmap(selectedBitmap);
        }
    }
}

It is pretty easy for me to implement and also shows darken areas.

A lot of these answers are simplistic, and if someone is beginning WPF, they may not know all of the "ins-and-outs", as it is more complicated than just telling someone "Use .ShowDialog()!". But that is the method (not .Show()) that you want to use in order to block use of the underlying window and to keep the code from continuing until the modal window is closed.

First, you need 2 WPF windows. (One will be calling the other.)

From the first window, let's say that was called MainWindow.xaml, in its code-behind will be:

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }
}

Then add your button to your XAML:

<Button Name="btnOpenModal" Click="btnOpenModal_Click" Content="Open Modal" />

And right-click the Click routine, select "Go to definition". It will create it for you in MainWindow.xaml.cs:

private void btnOpenModal_Click(object sender, RoutedEventArgs e)
{
}

Within that function, you have to specify the other page using its page class. Say you named that other page "ModalWindow", so that becomes its page class and is how you would instantiate (call) it:

private void btnOpenModal_Click(object sender, RoutedEventArgs e)
{
    ModalWindow modalWindow = new ModalWindow();
    modalWindow.ShowDialog();
}

Say you have a value you need set on your modal dialog. Create a textbox and a button in the ModalWindow XAML:

<StackPanel Orientation="Horizontal">
    <TextBox Name="txtSomeBox" />
    <Button Name="btnSaveData" Click="btnSaveData_Click" Content="Save" /> 
</StackPanel>

Then create an event handler (another Click event) again and use it to save the textbox value to a public static variable on ModalWindow and call this.Close().

public partial class ModalWindow : Window
{
    public static string myValue = String.Empty;        
    public ModalWindow()
    {
        InitializeComponent();
    }

    private void btnSaveData_Click(object sender, RoutedEventArgs e)
    {
        myValue = txtSomeBox.Text;
        this.Close();
    }
}

Then, after your .ShowDialog() statement, you can grab that value and use it:

private void btnOpenModal_Click(object sender, RoutedEventArgs e)
{
    ModalWindow modalWindow = new ModalWindow();
    modalWindow.ShowDialog();

    string valueFromModalTextBox = ModalWindow.myValue;
}

You may run:

git log <SHA1>..HEAD --ancestry-path --merges

From comment of last commit in the output you may find original branch name

Example:

       c---e---g--- feature
      /         \
-a---b---d---f---h---j--- master

git log e..master --ancestry-path --merges

    Merge branch 'feature' into master

Both of the previous 2 answers have at least O(n) time complexity and the string conversion has O(n) space complexity too. Here's a solution for constant time and space:

num // 10 ** (int(math.log(num, 10)) - 1)

Function:

import math

def first_n_digits(num, n):
    return num // 10 ** (int(math.log(num, 10)) - n + 1)

Output:

>>> first_n_digits(123456, 1)
1
>>> first_n_digits(123456, 2)
12
>>> first_n_digits(123456, 3)
123
>>> first_n_digits(123456, 4)
1234
>>> first_n_digits(123456, 5)
12345
>>> first_n_digits(123456, 6)
123456

You will need to add some checks if it's possible that your input number has less digits than you want.

From the Java EE documentation:

public abstract boolean unique

(Optional) Whether the property is a unique key. This is a shortcut for the UniqueConstraint annotation at the table level and is useful for when the unique key constraint is only a single field. This constraint applies in addition to any constraint entailed by primary key mapping and to constraints specified at the table level.

See doc

Since the problem is the non-trivial destructor so if the destructor is removed from the std::string, it's possible to define a constexpr instance of that type. Like this

struct constexpr_str {
    char const* str;
    std::size_t size;

    // can only construct from a char[] literal
    template <std::size_t N>
    constexpr constexpr_str(char const (&s)[N])
        : str(s)
        , size(N - 1) // not count the trailing nul
    {}
};

int main()
{
    constexpr constexpr_str s("constString");

    // its .size is a constexpr
    std::array<int, s.size> a;
    return 0;
}

Not the best method, use an array instead. This is just an alternative method.

http://www.w3schools.com/jsref/jsref_getday.asp

var date = new Date();
var day = date.getDay();

You should really use google before you post here.

Since other people posted the array method I'll show you an alternative way using a switch statement.

switch(day) {
    case 0:
        day = "Sunday";
        break;
    case 1:
        day = "Monday";
        break;

    ... rest of cases

    default:
        // do something
        break;
}

The above works, however, the array is the better alternative. You may also use if() statements however a switch statement would be much cleaner then several if's.

As eaon21 and monkey said, source map files basically turn minified code into its unminified version for debugging.

You can find the .map files here. Just add them into the same directory as the minified js files and it'll stop complaining. The reason they get fetched is the

/*
//@ sourceMappingURL=angular.min.js.map
*/

at the end of angular.min.js. If you don't want to add the .map files you can remove those lines and it'll stop the fetch attempt, but if you plan on debugging it's always good to keep the source maps linked.

I wanted to share one more important finding.

use of <%= variable => would result in cross-site scripting vulnerability. So its more safe to use <%- variable -> instead.

We had to replace <%= with <%- to prevent cross-site scripting attacks. Not sure, whether this will it have any impact on the performance

Just kill all node process and start npm server and run application:

Step1: run command killall -9 node

For windows users, run: taskkill /im node.exe

Run taskkill /f /im node.exe if the process still persists.

Step2: run command npm start --reset-cache

Step3: run command react-native run-ios OR react-native run-android

This is now possible for Files, select the file then select Actions > Rename in the GUI.

To rename a folder, you instead have to create a new folder, and select the contents of the old one and copy/paste it across (Under "Actions" again)

Callbacks are most easily described in terms of the telephone system. A function call is analogous to calling someone on a telephone, asking her a question, getting an answer, and hanging up; adding a callback changes the analogy so that after asking her a question, you also give her your name and number so she can call you back with the answer. -- Paul Jakubik , "Callback Implementations in C++"

Type echo $JAVA_HOME in your terminal to be sure your JAVA_HOME is set.

You can also type java -version to know what version of java you are actually using.

By the way, reading your description it seems your actually writing

export JAVA_HOME=/usr/lib/jvm/java-1.6.0-openjdk

in the file conf/hadoop-env.sh, you should write it in your terminal or in ~/.bashrc or ~/.profile then type source < path to modified file >.

If you don't need the gap to be exactly 2 lines high, you can add an empty view like this:

    <View
        android:layout_width="fill_parent"
        android:layout_height="30dp">
    </View>

ROWS UNBOUNDED PRECEDING is no Teradata-specific syntax, it's Standard SQL. Together with the ORDER BY it defines the window on which the result is calculated.

Logically a Windowed Aggregate Function is newly calculated for each row within the PARTITION based on all ROWS between a starting row and an ending row.

Starting and ending rows might be fixed or relative to the current row based on the following keywords:

• CURRENT ROW, the current row
• UNBOUNDED PRECEDING, all rows before the current row -> fixed
• UNBOUNDED FOLLOWING, all rows after the current row -> fixed
• x PRECEDING, x rows before the current row -> relative
• y FOLLOWING, y rows after the current row -> relative

Possible kinds of calculation include:

• Both starting and ending row are fixed, the window consists of all rows of a partition, e.g. a Group Sum, i.e. aggregate plus detail rows
• One end is fixed, the other relative to current row, the number of rows increases or decreases, e.g. a Running Total, Remaining Sum
• Starting and ending row are relative to current row, the number of rows within a window is fixed, e.g. a Moving Average over n rows

So SUM(x) OVER (ORDER BY col ROWS UNBOUNDED PRECEDING) results in a Cumulative Sum or Running Total

11 -> 11
 2 -> 11 +  2                = 13
 3 -> 13 +  3 (or 11+2+3)    = 16
44 -> 16 + 44 (or 11+2+3+44) = 60

I'm able to get the Class of the generic type this way:

class MyList<T> {
  Class<T> clazz = (Class<T>) DAOUtil.getTypeArguments(MyList.class, this.getClass()).get(0);
}

You need two functions from this file: http://code.google.com/p/hibernate-generic-dao/source/browse/trunk/dao/src/main/java/com/googlecode/genericdao/dao/DAOUtil.java

For more explanation: http://www.artima.com/weblogs/viewpost.jsp?thread=208860

I recommend, you change your loop algorithm:

• Add the comma not AFTER the item, but BEFORE
• Use a boolean variable, that starts with false, do suppress the first comma
• Set this boolean variable to true after testing it

You can use java.security.MessageDigest with SHA as your algorithm choice.

For reference,

Try available example here

<div *ngIf="currentStatus !== ('status1' || 'status2' || 'status3' || 'status4')">

I had to use strcpy_s and it worked.

#include "stdafx.h"
#include<iostream>
#include<string>

using namespace std;

struct student
{
    char name[30];
    int age;
};

int main()
{

    struct student s1;
    char myname[30] = "John";
    strcpy_s (s1.name, strlen(myname) + 1 ,myname );
    s1.age = 21;

    cout << " Name: " << s1.name << " age: " << s1.age << endl;
    return 0;
}

In my case it was a big modular project and the 'red X' was showing only in the parent project. I went to the parent project

Properties -> Built Path

a removed the JRE Library there, just that, no JRE Library on the parent project anymore.

This problem appear if two software use same port
generally Android studio use the port 5037
try to close the port by cmd according to your operating system
then reboot your Android studio or your Eclipse

info frame to show the stack frame info

To read the memory at given addresses you should take a look at x

x/x $esp for hex x/d $esp for signed x/u $esp for unsigned etc. x uses the format syntax, you could also take a look at the current instruction via x/i $eip etc.

Here a reusable and more generic approach for Java 8+ that does not require external libraries:

public interface IUnreliable<T extends Exception>
{
    void tryRun ( ) throws T;
}

public static <T extends Exception> void retry (int retryCount, IUnreliable<T> runnable) throws T {
    for (int retries = 0;; retries++) {
        try {
            runnable.tryRun();
            return;
        } catch (Exception e) {
            if (retries < retryCount) {
                continue;
            } else {
                throw e;
            }
        }
    }
}

Usage:

@Test
public void demo() throws IOException {
    retry(3, () -> {
        new File("/tmp/test.txt").createNewFile();
    });
}

Change the .env file as follow

MAIL_DRIVER=smtp
MAIL_HOST=smtp.googlemail.com
MAIL_PORT=587
[email protected]
MAIL_PASSWORD=password
MAIL_ENCRYPTION=tls

And the go to the gmail security section ->Allow Less secure app access

Then run

php artisan config:clear

You can't, since dict is unordered. you can use .popitem() to get an arbitrary item, but that will remove it from the dict.

declare @n int = 7,
    @m int = 3;

select 
    case 
        when @n = 1 then
            'SOMETEXT'
    else
        case 
            when @m = 1 then
                'SOMEOTHERTEXT'
            when @m = 2 then
                'SOMEOTHERTEXTGOESHERE'
        end
    end as col1
-- n=1 => returns SOMETEXT regardless of @m
-- n=2 and m=1 => returns SOMEOTHERTEXT
-- n=2 and m=2 => returns SOMEOTHERTEXTGOESHERE
-- n=2 and m>2 => returns null (no else defined for inner case)

I could not find a single good answer that helped me get rid of this issue.

Let's say the name of branch, you accidentally committed changes to, is master. Following four simple steps proved like a world to me:

1. Go to Branches
2. Choose or create any branch other than master
3. Delete local/workspace version of master
4. Switch to master from remotes/origin

I've recently started doing something like this:

public class Main {
    @FunctionalInterface
    public interface NotDotNetDelegate {
        int doSomething(int a, int b);
    }

    public static void main(String[] args) {
        // in java 8 (lambdas):
        System.out.println(functionThatTakesDelegate((a, b) -> {return a*b;} , 10, 20));

    }

    public static int functionThatTakesDelegate(NotDotNetDelegate del, int a, int b) {
        // ...
        return del.doSomething(a, b);
    }
}

Solution 1:

display:table-cell (not widely supported)

Solution 2:

tables

(I hate hacks.)

First off you can't have just a number for your id unless you are using the HTML5 DOCTYPE. Secondly, you need to either remove the # in each id or replace it with this:

$container.cycle(id.replace('#','')); 

This is yet another bash & python hybrid answer. I posted this answer because I wanted to process more complex JSON output, but, reducing the complexity of my bash application. I want to crack open the following JSON object from http://www.arcgis.com/sharing/rest/info?f=json in bash:

{
  "owningSystemUrl": "http://www.arcgis.com",
  "authInfo": {
    "tokenServicesUrl": "https://www.arcgis.com/sharing/rest/generateToken",
    "isTokenBasedSecurity": true
  }
}

In the following example, I created my own implementation of jq and unquote leveraging python. You'll note that once we import the python object from json to a python dictionary we can use python syntax to navigate the dictionary. To navigate the above, the syntax is:

• data
• data[ "authInfo" ]
• data[ "authInfo" ][ "tokenServicesUrl" ]

By using magic in bash, we omit data and only supply the python text to the right of data, i.e.

• jq
• jq '[ "authInfo" ]'
• jq '[ "authInfo" ][ "tokenServicesUrl" ]'

Note, with no parameters, jq acts as a JSON prettifier. With parameters, we can use python syntax to extract anything we want from the dictionary including navigating subdictionaries and array elements.

Here are the bash python hybrid functions:

#!/bin/bash -xe

jq_py() {
  cat <<EOF
import json, sys
data = json.load( sys.stdin )
print( json.dumps( data$1, indent = 4 ) )
EOF
}

jq() {
  python -c "$( jq_py "$1" )"
}

unquote_py() {
  cat <<EOF
import json,sys
print( json.load( sys.stdin ) )
EOF
}

unquote() {
  python -c "$( unquote_py )"
}

Here's a sample usage of the bash python functions:

curl http://www.arcgis.com/sharing/rest/info?f=json | tee arcgis.json
# {"owningSystemUrl":"https://www.arcgis.com","authInfo":{"tokenServicesUrl":"https://www.arcgis.com/sharing/rest/generateToken","isTokenBasedSecurity":true}}

cat arcgis.json | jq
# {
#     "owningSystemUrl": "https://www.arcgis.com",
#     "authInfo": {
#         "tokenServicesUrl": "https://www.arcgis.com/sharing/rest/generateToken",
#         "isTokenBasedSecurity": true
#     }
# }

cat arcgis.json | jq '[ "authInfo" ]'
# {
#     "tokenServicesUrl": "https://www.arcgis.com/sharing/rest/generateToken",
#     "isTokenBasedSecurity": true
# }

cat arcgis.json | jq '[ "authInfo" ][ "tokenServicesUrl" ]'
# "https://www.arcgis.com/sharing/rest/generateToken"

cat arcgis.json | jq '[ "authInfo" ][ "tokenServicesUrl" ]' | unquote
# https://www.arcgis.com/sharing/rest/generateToken

First you need to separate your class from the further extensions ex you cannot extend AddAddressComponent.defaultProps within the class instead move it outside.

I will also recommend you to read about the Constructor and React's lifecycle: see Component Specs and Lifecycle

Here is what you want:

import PropTypes from 'prop-types';

class AddAddressComponent extends React.Component {
  render() {
    let { provinceList, cityList } = this.props;
    if(cityList === undefined || provinceList === undefined){
      console.log('undefined props');
    }
  }
}

AddAddressComponent.contextTypes = {
  router: PropTypes.object.isRequired
};

AddAddressComponent.defaultProps = {
  cityList: [],
  provinceList: [],
};

AddAddressComponent.propTypes = {
  userInfo: PropTypes.object,
  cityList: PropTypes.array.isRequired,
  provinceList: PropTypes.array.isRequired,
}

export default AddAddressComponent;

JVM head dump is a snapshot of a JVM heap memory in a given time. So its simply a heap representation of JVM. That is the state of the objects.

JVM thread dump is a snapshot of a JVM threads at a given time. So thats what were threads doing at any given time. This is the state of threads. This helps understanding such as locked threads, hanged threads and running threads.

Head dump has more information of java class level information than a thread dump. For example Head dump is good to analyse JVM heap memory issues and OutOfMemoryError errors. JVM head dump is generated automatically when there is something like OutOfMemoryError has taken place. Heap dump can be created manually by killing the process using kill -3 . Generating a heap dump is a intensive computing task, which will probably hang your jvm. so itsn't a methond to use offetenly. Heap can be analysed using tools such as eclipse memory analyser.

Core dump is a os level memory usage of objects. It has more informaiton than a head dump. core dump is not created when we kill a process purposely.

Perhaps it is late for the party. But there is an alternative solution for this is to use ApiMultipartFormFormatter plugin.

This plugin helps you to receive the multipart/formdata content as ASP.NET Core does.

In the github page, demo is already provided.

You could use sp_executesql instead of exec. That allows you to specify an output parameter.

declare @out_var varchar(max);
execute sp_executesql 
    N'select @out_var = ''hello world''', 
    N'@out_var varchar(max) OUTPUT', 
    @out_var = @out_var output;
select @out_var;

This prints "hello world".

Do you mean like this?

var hello1 = document.getElementById('hello1');
hello1.id = btoa(hello1.id);

To further the example, say you wanted to get all elements with the class 'abc'. We can use querySelectorAll() to accomplish this:

HTML

<div class="abc"></div>
<div class="abc"></div>

JS

var abcElements = document.querySelectorAll('.abc');

// Set their ids
for (var i = 0; i < abcElements.length; i++)
    abcElements[i].id = 'abc-' + i;

This will assign the ID 'abc-<index number>' to each element. So it would come out like this:

<div class="abc" id="abc-0"></div>
<div class="abc" id="abc-1"></div>

To create an element and assign an id we can use document.createElement() and then appendChild().

var div = document.createElement('div');
div.id = 'hello1';

var body = document.querySelector('body');
body.appendChild(div);

Update

You can set the id on your element like this if your script is in your HTML file.

<input id="{{str(product["avt"]["fto"])}}" >
<span>New price :</span>
<span class="assign-me">

<script type="text/javascript">
    var s = document.getElementsByClassName('assign-me')[0];
    s.id = btoa({{str(produit["avt"]["fto"])}});
</script>

Your requirements still aren't 100% clear though.

If the forked repo is protected so you can't push directly into it, and your goal is to make changes to their foo, then you need to get their branch foo into your repo like so:

git remote add protected_repo https://github.com/theirusername/their_repo.git
git fetch protected_repo 
git checkout --no-track protected_repo/foo

Now you have a local copy of foo with no upstream associated to it. You can commit changes to it (or not) and then push your foo to your own remote repo.

git push --set-upstream origin foo

Now foo is in your repo on GitHub and your local foo is tracking it. If they continue to make changes to foo you can fetch theirs and merge into your foo.

git checkout foo 
git fetch protected_repo
git merge protected_repo/foo

Gestures are those subtle motions to trigger interactions between the touch screen and the user. It lasts for the time between the first touch on the screen to the point when the last finger leaves the surface.

Android provides us with a class called GestureDetector using which we can detect common gestures like tapping down and up, swiping vertically and horizontally (fling), long and short press, double taps, etc. and attach listeners to them.

Make our Activity class implement GestureDetector.OnDoubleTapListener (for double tap gesture detection) and GestureDetector.OnGestureListener interfaces and implement all the abstract methods.For more info. you may visit https://developer.android.com/training/gestures/detector.html . Courtesy

Matt Johnsons answer is much better than this one was.

This seems to be the clearest and simplest example to me, this just appends property or replaces existing.

function replaceProperties(copyTo, copyFrom)  {
  for (var property in copyFrom) 
    copyTo[property] =  copyFrom[property]
  return copyTo
}

Save your files as ~/.config/fish/functions/{some_function_name}.fish and they should get autoloaded when you start fish.

Swift 5 Use button.setTitle()

1. If using storyboards, make a IBOutlet reference.

@IBOutlet weak var button: UIButton!

2. Call setTitle on the button followed by the text and the state.

button.setTitle("Button text here", forState: .normal)

$('a').click(function(){
 $('#content-container').html('My content here :-)');
});

this should work

$.validator.addMethod("endDate", function(value, element) {_x000D_
            var startDate = $('#date_open').val();_x000D_
            return Date.parse(startDate) <= Date.parse(value) || value == "";_x000D_
        }, "* End date must be after start date");

To prevent quirks mode, define a 'doctype' like :

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">

To make IE render the page in IE9 document mode :

<meta http-equiv="x-ua-compatible" content="IE=9">

Please note that "IE=edge" will make IE render the page with the most recent document mode, rather than IE9 document mode.

Better:

if cells(i,1)="" then 
nextEmpty=i: 
exit for

Another simple way would be add some log statement to the bar.someMethod() and then ascertain you can see the said message when your test executed, see examples here: How to do a JUnit assert on a message in a logger

That is especially handy when your Bar.someMethod() is private.

Sometimes your build folder simply needs cleaning - it certainly worked for me. Thanks to loafer-project for the solution.

The not straightforward way of doing it would be granting select on each table of the database:

postgres=# grant select on db_name.table_name to read_only_user;

You could automate that by generating your grant statements from the database metadata.

Docstrings (and documentation in general). Python 3 introduces (optional) function annotations, as described in PEP 3107 (but don't leave out docstrings)

This is inspired by Holstebroe's answer, plus comments here: Getting an Image object from a byte array

Bitmap newBitmap;
using (MemoryStream memoryStream = new MemoryStream(byteArrayIn))
    using (Image newImage = Image.FromStream(memoryStream))
        newBitmap = new Bitmap(newImage);
return newBitmap;

To me, it seems as if your actual intention is to put different words on different lines. But let me answer your first question:

JLabel lab=new JLabel("text");
lab.setHorizontalAlignment(SwingConstants.LEFT);     

And if you have an image:

JLabel lab=new Jlabel("text");
lab.setIcon(new ImageIcon("path//img.png"));
lab.setHorizontalTextPosition(SwingConstants.LEFT);

But, I believe you want to make the label such that there are only 2 words on 1 line.

In that case try this:

String urText="<html>You can<br>use basic HTML<br>in Swing<br> components," 
   +"Hope<br> I helped!";
JLabel lac=new JLabel(urText);
lac.setAlignmentX(Component.RIGHT_ALIGNMENT);

font-family:'Open Sans' , sans-serif;

For light: font-weight : 100; Or font-weight : lighter;

For normal: font-weight : 500; Or font-weight : normal;

For bold: font-weight : 700; Or font-weight : bold;

For more bolder: font-weight : 900; Or font-weight : bolder;

none of that needed.... just go to:

I'm new to Python, but found a way to convert

2017-05-27T07:20:18.000-04:00 to

2017-05-27T07:20:18 without downloading new utilities.

from datetime import datetime, timedelta

time_zone1 = int("2017-05-27T07:20:18.000-04:00"[-6:][:3])
>>returns -04

item_date = datetime.strptime("2017-05-27T07:20:18.000-04:00".replace(".000", "")[:-6], "%Y-%m-%dT%H:%M:%S") + timedelta(hours=-time_zone1)

I'm sure there are better ways to do this without slicing up the string so much, but this got the job done.

While looping through your string one character at a time is a viable method, there's no need. VBA has built-in functions for this kind of thing:

Public Function ProcessString(input_string As String) As String
    ProcessString=Replace(input_string,"*","")
End Function

With JavaScript it is very difficult if not impossible(?). I would suggest using some sort of code-behind language such as PHP, C#, or Java. If you were to use PHP, you could, in the page your button posts to, do something like this:

<?php
header('Content-type: application/pdf');
header('Content-disposition: attachment; filename=filename.pdf');
readfile("http://manuals.info.apple.com/en/iphone_user_guide.pdf");
?>

This also seems to work for JS (from http://www.phpbuilder.com/board/showthread.php?t=10149735):

<body>
<script>
function downloadme(x){
myTempWindow = window.open(x,'','left=10000,screenX=10000');
myTempWindow.document.execCommand('SaveAs','null','download.pdf');
myTempWindow.close();
}
</script>

My team moved away from Bower and migrated to npm because:

• Programmatic usage was painful
• Bower's interface kept changing
• Some features, like the url shorthand, are entirely broken
• Using both Bower and npm in the same project is painful
• Keeping bower.json version field in sync with git tags is painful
• Source control != package management
• CommonJS support is not straightforward

For more details, see "Why my team uses npm instead of bower".

SVG has properties width and height. They return an object SVGAnimatedLength with two properties: animVal and baseVal. This interface is used for animation, where baseVal is the value before animation. From what I can see, this method returns consistent values in both Chrome and Firefox, so I think it can also be used to get calculated size of SVG.

I faced a similar problem but in my case I was trying to install Visual C++ Redistributable for Visual Studio 2015 Update 1 on Windows Server 2012 R2. However the root cause should be the same.

In short, you need to install the prerequisites of KB2999226.

In more details, the installation log I got stated that the installation for Windows Update KB2999226 failed. According to the Microsoft website here:

Prerequisites To install this update, you must have April 2014 update rollup for Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2 (2919355) installed in Windows 8.1 or Windows Server 2012 R2. Or, install Service Pack 1 for Windows 7 or Windows Server 2008 R2. Or, install Service Pack 2 for Windows Vista and for Windows Server 2008.

After I have installed April 2014 on my Windows Server 2012 R2, I am able to install the Visual C++ Redistributable correctly.

Try this

$('#testID').addClass('nameOfClass');

or

$('#testID').removeClass('nameOfClass');

No, this is, as you say "rubbish code". If it works as should, it is because browsers try to "read the writer's mind" - in other words, they have algorithms to try to make sense of "rubbish code", guess at the probable intent and internally change it into something that actually makes sense.

In other words, your code only works by accident, and probably not in all browsers.

Is this what you're trying to do?

<a href="#" onClick="alert('Hello World!')"><img title="The Link" /></a>

I had a similar issue, and for me the issue was due to some missing semicolons in the controller. The minification of the app was probably causing the code to execute incorrectly (most likely the resulting code was causing state mutations, which causes the view to render, and then the controller executes the code again, and so on recursively).

You're doing things in the wrong order.

You need to first add all JComponents to the JFrame, and only then call pack() and then setVisible(true) on the JFrame

If you later added JComponents that could change the GUI's size you will need to call pack() again, and then repaint() on the JFrame after doing so.

I realize I'm a bit late to this party, but here's my two cents.

We're all clear that Enum inheritance is not supported by the framework. Some very interesting workarounds have been suggested in this thread, but none of them felt quite like what I was looking for, so I had a go at it myself.

Introducing: ObjectEnum

You can check the code and documentation here: https://github.com/dimi3tron/ObjectEnum.

And the package here: https://www.nuget.org/packages/ObjectEnum

Or just install it: Install-Package ObjectEnum

In short, ObjectEnum<TEnum> acts as a wrapper for any enum. By overriding the GetDefinedValues() in subclasses, one can specify which enum values are valid for this specific class.

A number of operator overloads have been added to make an ObjectEnum<TEnum> instance behave as if it were an instance of the underlying enum, keeping in mind the defined value restrictions. This means you can easily compare the instance to an int or enum value, and thus use it in a switch case or any other conditional.

I'd like to refer to the github repo mentioned above for examples and further info.

I hope you find this useful. Feel free to comment or open an issue on github for further thoughts or comments.

Here are a few short examples of what you can do with ObjectEnum<TEnum>:

var sunday = new WorkDay(DayOfWeek.Sunday); //throws exception
var monday = new WorkDay(DayOfWeek.Monday); //works fine
var label = $"{monday} is day {(int)monday}." //produces: "Monday is day 1."
var mondayIsAlwaysMonday = monday == DayOfWeek.Monday; //true, sorry...

var friday = new WorkDay(DayOfWeek.Friday);

switch((DayOfWeek)friday){
    case DayOfWeek.Monday:
        //do something monday related
        break;
        /*...*/
    case DayOfWeek.Friday:
        //do something friday related
        break;
}

Write someMethod() in this way:

public void someMethod() {

    SomeClass.AnotherClass.MyEnum enumExample = SomeClass.AnotherClass.MyEnum.VALUE_A;

    switch (enumExample) {
    case VALUE_A:
        break;
    }

}

In switch statement you must use the constant name only.

I had the same problem when I upgraded jquery UI to 1.8.1 without upgrading the corresponding theme. Only is needed to upgrade the theme too and "auto" works again.

json.dumps() is used to decode JSON data

• json.loads take a string as input and returns a dictionary as output.
• json.dumps take a dictionary as input and returns a string as output.

import json

# initialize different data
str_data = 'normal string'
int_data = 1
float_data = 1.50
list_data = [str_data, int_data, float_data]
nested_list = [int_data, float_data, list_data]
dictionary = {
    'int': int_data,
    'str': str_data,
    'float': float_data,
    'list': list_data,
    'nested list': nested_list
}

# convert them to JSON data and then print it
print('String :', json.dumps(str_data))
print('Integer :', json.dumps(int_data))
print('Float :', json.dumps(float_data))
print('List :', json.dumps(list_data))
print('Nested List :', json.dumps(nested_list, indent=4))
print('Dictionary :', json.dumps(dictionary, indent=4))  # the json data will be indented

output:

String : "normal string"
Integer : 1
Float : 1.5
List : ["normal string", 1, 1.5]
Nested List : [
    1,
    1.5,
    [
        "normal string",
        1,
        1.5
    ]
]
Dictionary : {
    "int": 1,
    "str": "normal string",
    "float": 1.5,
    "list": [
        "normal string",
        1,
        1.5
    ],
    "nested list": [
        1,
        1.5,
        [
            "normal string",
            1,
            1.5
        ]
    ]
}

Use the below. It takes the local datetime and converts it to UTC using the timezone. You do not need to create it function.

ZonedDateTime nowUTC = ZonedDateTime.now(ZoneOffset.UTC);
System.out.println(nowUTC.toString());

If you need to obtain the LocalDateTime part of the ZonedDateTime then you can use the following.

nowUTC.toLocalDateTime();

Here is a static method i use in my application to insert UTC time in mysql since i cannot add a default value UTC_TIMESTAMP to a datetime column.

public static LocalDateTime getLocalDateTimeInUTC(){
    ZonedDateTime nowUTC = ZonedDateTime.now(ZoneOffset.UTC);

    return nowUTC.toLocalDateTime();
}

Quick answer for single line span

Make the child (in this case a span) the same line-height as the parent <div>'s height

<div class="parent">
  <span class="child">Yes mom, I did my homework lol</span>
</div>

You should then add the CSS rules

.parent { height: 20px; }
.child { line-height: 20px; vertical-align: middle; }

Or you can target it with a child selector

.parent { height: 20px; }
.parent > span { line-height: 20px; vertical-align: middle; }

Background on my own use of this

I ran into this similar issue where I needed to vertically center items in a mobile menu. I made the div and spans inside the same line height. Note that this is for a meteor project and therefore not using inline css ;)

HTML

<div class="international">        
  <span class="intlFlag">
    {{flag}}        
  </span>

  <span class="intlCurrent">
    {{country}}
  </span>

  <span class="intlButton">
    <i class="fa fa-globe"></i>
  </span> 
</div>

CSS (option for multiple spans in a div)

.international {
  height: 42px;
}

.international > span {
  line-height: 42px;
}

In this case if I just had one span I could have added the CSS rule directly to that span.

CSS (option for one specific span)

.intlFlag { line-height: 42px; }

Here is how it displayed for me

See C# switch statement limitations - why?

Basically Switches cannot have evaluated statements in the case statement. They must be statically evaluated.

Without any example data, it really is difficult to know exactly what you are wanting. For instance, I can't at all divine what your object set (or is it sets) looks like.

That said, does the following help at all?

set1 <- data.frame(x = 4:6, y = 6:4, z = c(1, 3, 5))

plot(1:10, type="n")
XX <- "set1"
with(eval(as.symbol(XX)), symbols(x, y, circles = z, add=TRUE))

EDIT:

Now that I see your real task, here is a one-liner that'll do everything you want without requiring any for() loops:

with(dat, symbols(sq, cu, circles = num,
                  bg = c("red", "blue")[(num>5) + 1]))

The one bit of code that may feel odd is the bit specifying the background color. Try out these two lines to see how it works:

c(TRUE, FALSE) + 1
# [1] 2 1
c("red", "blue")[c(F, F, T, T) + 1]
# [1] "red"  "red"  "blue" "blue"

It should be saved. It should be like this :

     db. my_collection.find({}).forEach(function(theCollection) {
         theCollection.moop = parseInt(theCollection.moop);
        db.my_collection.save(theCollection);
     });

I think the problem you're having is that in some earlier commit, you've accidentally added .DS_Store files to the repository. Of course, once a file is tracked in your repository, it will continue to be tracked even if it matches an entry in an applicable .gitignore file.

You have to manually remove the .DS_Store files that were added to your repository. You can use

git rm --cached .DS_Store

Once removed, git should ignore it. You should only need the following line in your root .gitignore file: .DS_Store. Don't forget the period!

git rm --cached .DS_Store

removes only .DS_Store from the current directory. You can use

find . -name .DS_Store -print0 | xargs -0 git rm --ignore-unmatch

to remove all .DS_Stores from the repository.

Felt tip: Since you probably never want to include .DS_Store files, make a global rule. First, make a global .gitignore file somewhere, e.g.

echo .DS_Store >> ~/.gitignore_global

Now tell git to use it for all repositories:

git config --global core.excludesfile ~/.gitignore_global

This page helped me answer your question.

I recommend using http://jsbeautifier.org/ - if you paste your code snippet into it and press beautify, the error is immediately visible.

You can do (pre-Java 8):

List<Enum> enumValues = Arrays.asList(Enum.values());

or

List<Enum> enumValues = new ArrayList<Enum>(EnumSet.allOf(Enum.class));

Using Java 8 features, you can map each constant to its name:

List<String> enumNames = Stream.of(Enum.values())
                               .map(Enum::name)
                               .collect(Collectors.toList());

Do this if you absolutely need to use the -Format option:

$dateStr = Get-Date $date -Format "yyyMMdd"

However

$dateStr = $date.toString('yyyMMdd')

is probably more efficient.. :)

For enum type, I think this is a suitable way, and the difference between class is how to calculate hash value.

template <typename T>
struct EnumTypeHash {
  std::size_t operator()(const T& type) const {
    return static_cast<std::size_t>(type);
  }
};

enum MyEnum {};
class MyValue {};

std::unordered_map<MyEnum, MyValue, EnumTypeHash<MyEnum>> map_;

It will create a table and copy all the data from old table to new table

SELECT * INTO event_log_temp FROM event_log

And you can clear the old table data.

DELETE FROM event_log

For those who care about performance take out the System.out and limit the loop to 1 byte. Using double (test 1/2) and using String (3/4) the elapsed times in milliseconds is given below with Windows 7 Professional 64 bit and JDK-1.7.0_21. Bytecodes (also given below for test1 and test2) are not the same. I was too lazy to test with mutable & relatively complex objects.

double

Test1 took: 2710 msecs

Test2 took: 2790 msecs

String (just replace double with string in the tests)

Test3 took: 1200 msecs

Test4 took: 3000 msecs

UPDATED ANSWER

It's really not easy to compare performance with all the JVM optimizations. However, it is somewhat possible. Better test and detailed results in Google Caliper

1. Some details on blog:Should you declare a variable inside a loop or before the loop?
2. GitHub repository: https://github.com/gunduru/jvdt
3. Test Results for double case and 100M loop (and yes all JVM details): https://microbenchmarks.appspot.com/runs/b1cef8d1-0e2c-4120-be61-a99faff625b4

• DeclaredBefore 1,759.209 ns
• DeclaredInside 2,242.308 ns

Partial Test Code for double Declaration

This is not identical to the code above. If you just code a dummy loop JVM skips it, so at least you need to assign and return something. This is also recommended in Caliper documentation.

@Param int size; // Set automatically by framework, provided in the Main
/**
* Variable is declared inside the loop.
*
* @param reps
* @return
*/
public double timeDeclaredInside(int reps) {
    /* Dummy variable needed to workaround smart JVM */
    double dummy = 0;

    /* Test loop */
    for (double i = 0; i <= size; i++) {

        /* Declaration and assignment */
        double test = i;

        /* Dummy assignment to fake JVM */
        if(i == size) {
            dummy = test;
        }
    }
    return dummy;
}

/**
* Variable is declared before the loop.
*
* @param reps
* @return
*/
public double timeDeclaredBefore(int reps) {

    /* Dummy variable needed to workaround smart JVM */
    double dummy = 0;

    /* Actual test variable */
    double test = 0;

    /* Test loop */
    for (double i = 0; i <= size; i++) {

        /* Assignment */
        test = i;

        /* Not actually needed here, but we need consistent performance results */
        if(i == size) {
            dummy = test;
        }
    }
    return dummy;
}

Summary: declaredBefore indicates better performance -really tiny- and it's against the smallest scope principle. JVM should actually do this for you

Another situation which issues the same problem, map.entrySet().iterator().next()

If there is no element in the Map object, then the above code will return NoSuchElementException. Make sure to call hasNext() first.

You need to have the apk installed and running in front on your phone for this solution:

Windows CMD line:

adb shell dumpsys window windows | findstr <any unique string from your pkg Name>

Linux Terminal:

    WindowStateAnimator{3e160d22 com.android.calculator2/com.android.calculator2.Calculator}:

      mSurface=Surface(name=com.android.calculator2/com.android.calculator2.Calculator)

  mCurrentFocus=Window{39ced4b1 u0 com.android.calculator2/com.android.calculator2.Calculator}

  mFocusedApp=AppWindowToken{29a4bed4 token=Token{2f850b1a ActivityRecord{eefe5c5 u0 com.android.calculator2/.Calculator t322}}}

Main part is, First Line:

Window #7 Window{39ced4b1 u0 com.android.calculator2/com.android.calculator2.Calculator}:

First part of the output is package name:

com.android.calculator2

Second Part of output (which is after /) can be two things, in our case its:

com.android.calculator2.Calculator

1. <PKg name>.<activity name> = <com.android.calculator2>.<Calculator>

   so .Calculator is our activity

2. If second part is entirely different from Package name and doesn't seem to contain pkg name which was before / in out output, then entire second part can be used as main activity.

As per @Quasimondo's comment, which seems to have been largely missed, the below seems to have the best performance as shown here: https://jsperf.com/finding-maximum-element-in-an-array. Note that while for the array in the question, performance may not have a significant effect, for large arrays performance becomes more important, and again as noted using Math.max() doesn't even work if the array length is more than 65535. See also this answer.

function largestNum(arr) {
    var d = data;
    var m = d[d.length - 1];
    for (var i = d.length - 1; --i > -1;) {
      if (d[i] > m) m = d[i];
    }
    return m;
}

An option for delegates in C++ that is not otherwise mentioned here is to do it C style using a function ptr and a context argument. This is probably the same pattern that many asking this question are trying to avoid. But, the pattern is portable, efficient, and is usable in embedded and kernel code.

class SomeClass
{
    in someMember;
    int SomeFunc( int);

    static void EventFunc( void* this__, int a, int b, int c)
    {
        SomeClass* this_ = static_cast< SomeClass*>( this__);

        this_->SomeFunc( a );
        this_->someMember = b + c;
    }
};

void ScheduleEvent( void (*delegateFunc)( void*, int, int, int), void* delegateContext);

    ...
    SomeClass* someObject = new SomeObject();
    ...
    ScheduleEvent( SomeClass::EventFunc, someObject);
    ...

I read through all these, but wanted something a bit more elegant. Just to remove a certain number of characters from the end of a string:

string.Concat("hello".Reverse().Skip(3).Reverse());

output:

"he"

Don't use sed, use cut:

grep .... | cut -c 1-N

If you MUST use sed:

grep ... | sed -e 's/^\(.\{12\}\).*/\1/'

You can use itoa function to convert the integer to a string.

You can use strcat function to append characters in a string at the end of another string.

If you want to convert a integer to a character, just do the following -

int a = 65;
char c = (char) a;

Note that since characters are smaller in size than integer, this casting may cause a loss of data. It's better to declare the character variable as unsigned in this case (though you may still lose data).

To do a light reading about type conversion, go here.

If you are still having trouble, comment on this answer.

Edit

Go here for a more suitable example of joining characters.

Also some more useful link is given below -

1. http://www.cplusplus.com/reference/clibrary/cstring/strncat/
2. http://www.cplusplus.com/reference/clibrary/cstring/strcat/

Second Edit

char msg[200];
int msgLength;
char rankString[200];

........... // Your message has arrived
msgLength = strlen(msg);
itoa(rank, rankString, 10); // I have assumed rank is the integer variable containing the rank id

strncat( msg, rankString, (200 - msgLength) );  // msg now contains previous msg + id

// You may loose some portion of id if message length + id string length is greater than 200

Third Edit

Go to this link. Here you will find an implementation of itoa. Use that instead.

Polish-> English (VS on MAC) answer: When I started a project and was forced to download Visual Studio, went to their page and saw that Microsoft logo I knew there would be problems... And here it is. It occurred difficult to change the language of VS on Mac. My OS is purely English and only because of the fact I downloaded it using a browser with Polish set as a default language I got the wrong version. I had to reinstall the version to the newest and then Visual Studio Community -> Preferences(in the environment section) -> Visual Style-> User Interface Language.

It translates to polish: Visual Studio Community -> Preferencje -> Styl Wizualny w sekcji Srodowisko -> Jezyk interfejsu uzytkownika -> English.

If you don't see such an option then, as I was, you are forced to upgrade this crappy VS to the newest version.

Yes, I believe you are creating thousands of objects. If you're looking for an easy way to delete a bunch of them at once, use canvas tags described here. This lets you perform the same operation (such as deletion) on a large number of objects.

With str(x). However, every data type can define its own string conversion, so this might not be what you want.

Had peno's version optimised a bit. The increase in performance is perceptible.

private boolean unpackZip(String path, String zipname)
{       
     InputStream is;
     ZipInputStream zis;
     try 
     {
         String filename;
         is = new FileInputStream(path + zipname);
         zis = new ZipInputStream(new BufferedInputStream(is));          
         ZipEntry ze;
         byte[] buffer = new byte[1024];
         int count;

         while ((ze = zis.getNextEntry()) != null) 
         {
             filename = ze.getName();

             // Need to create directories if not exists, or
             // it will generate an Exception...
             if (ze.isDirectory()) {
                File fmd = new File(path + filename);
                fmd.mkdirs();
                continue;
             }

             FileOutputStream fout = new FileOutputStream(path + filename);

             while ((count = zis.read(buffer)) != -1) 
             {
                 fout.write(buffer, 0, count);             
             }

             fout.close();               
             zis.closeEntry();
         }

         zis.close();
     } 
     catch(IOException e)
     {
         e.printStackTrace();
         return false;
     }

    return true;
}

I believe your question is to change only width of view dynamically, whereas above methods will change layout properties completely to new one, so I suggest to getLayoutParams() from view first, then set width on layoutParams, and finally set layoutParams to the view, so following below steps to do the same.

View view = findViewById(R.id.nutrition_bar_filled);
LayoutParams layoutParams = view.getLayoutParams();
layoutParams.width = newWidth;
view.setLayoutParams(layoutParams);

Here's a simple example of how to load JSON data into an Angular model.

I have a JSON 'GET' web service which returns a list of Customer details, from an online copy of Microsoft's Northwind SQL Server database.

http://www.iNorthwind.com/Service1.svc/getAllCustomers

It returns some JSON data which looks like this:

{ 
    "GetAllCustomersResult" : 
        [
            {
              "CompanyName": "Alfreds Futterkiste",
              "CustomerID": "ALFKI"
            },
            {
              "CompanyName": "Ana Trujillo Emparedados y helados",
              "CustomerID": "ANATR"
            },
            {
              "CompanyName": "Antonio Moreno Taquería",
              "CustomerID": "ANTON"
            }
        ]
    }

..and I want to populate a drop down list with this data, to look like this...

I want the text of each item to come from the "CompanyName" field, and the ID to come from the "CustomerID" fields.

How would I do it ?

My Angular controller would look like this:

function MikesAngularController($scope, $http) {

    $scope.listOfCustomers = null;

    $http.get('http://www.iNorthwind.com/Service1.svc/getAllCustomers')
         .success(function (data) {
             $scope.listOfCustomers = data.GetAllCustomersResult;
         })
         .error(function (data, status, headers, config) {
             //  Do some error handling here
         });
}

... which fills a "listOfCustomers" variable with this set of JSON data.

Then, in my HTML page, I'd use this:

<div ng-controller='MikesAngularController'>
    <span>Please select a customer:</span>
    <select ng-model="selectedCustomer" ng-options="customer.CustomerID as customer.CompanyName for customer in listOfCustomers" style="width:350px;"></select>
</div>

And that's it. We can now see a list of our JSON data on a web page, ready to be used.

The key to this is in the "ng-options" tag:

customer.CustomerID as customer.CompanyName for customer in listOfCustomers

It's a strange syntax to get your head around !

When the user selects an item in this list, the "$scope.selectedCustomer" variable will be set to the ID (the CustomerID field) of that Customer record.

The full script for this example can be found here:

You can use a rewrite rule that uses ^$ to represent the root and rewrite that to your /store directory, like this:

RewriteEngine On
RewriteRule ^$ /store [L]

Very good question. The Java Language specification confirms your suggestion.

For example, the following code is correct:

short x = 3;
x += 4.6;

and results in x having the value 7 because it is equivalent to:

short x = 3;
x = (short)(x + 4.6);

use test
go
alter proc restore_mdf_ldf_main (@database varchar(100), @mdf varchar(100),@ldf varchar(100),@filename varchar(200))
as
begin 
begin try
RESTORE DATABASE @database FROM DISK = @FileName
with norecovery,
MOVE @mdf TO 'D:\sql samples\sample.mdf',
MOVE @ldf TO 'D:\sql samples\sample.ldf'
end try
begin catch
SELECT ERROR_MESSAGE() AS ErrorMessage;
print 'Restoring of the database ' + @database + ' failed';
end catch
end

exec restore_mdf_ldf_main product,product,product_log,'c:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\Backup\product.bak'

sed

• '/^[[:space:]]*$/d'
• '/^\s*$/d'
• '/^$/d'
• -n '/^\s*$/!p'

grep

• .
• -v '^$'
• -v '^\s*$'
• -v '^[[:space:]]*$'

awk

• /./
• 'NF'
• 'length'
• '/^[ \t]*$/ {next;} {print}'
• '!/^[ \t]*$/'

Just one more example how the character could be flipped. Add vendor prefixes if you need ones but for now all modern browsers support unprefixed transform property. The only exception is Opera if Opera Mini mode is enabled (~3% world users).

Here's the relevant section in the docs.

P.S. This, in fact, fully matches the answer in the referenced question.

You can't, but you can use BETWEEN

SELECT job FROM mytable WHERE id BETWEEN 10 AND 15

Note that BETWEEN is inclusive, and will include items with both id 10 and 15.

If you do not want inclusion, you'll have to fall back to using the > and < operators.

SELECT job FROM mytable WHERE id > 10 AND id < 15

The problem is your plugin. To solve this is to only enter this address:

chrome://flags/#enable-NPAPI

Click activate NPAPI, and finally restart at the bottom of the page.

You might want to use the reversed function in python. Before we jump in to the code we must remember that the range function always returns a list (or a tuple I don't know) so range(5) will return [0, 1, 2, 3, 4]. The reversed function reverses a list or a tuple so reversed(range(5)) will be [4, 3, 2, 1, 0] so your solution might be:

for i in reversed(range(100)):
    print(i)

If it is good enough to print to stderr, you can use the following streams originally intended for debugging:

#include<QDebug>

//qInfo is qt5.5+ only.
qInfo() << "C++ Style Info Message";
qInfo( "C Style Info Message" );

qDebug() << "C++ Style Debug Message";
qDebug( "C Style Debug Message" );

qWarning() << "C++ Style Warning Message";
qWarning( "C Style Warning Message" );

qCritical() << "C++ Style Critical Error Message";
qCritical( "C Style Critical Error Message" );

// qFatal does not have a C++ style method.
qFatal( "C Style Fatal Error Message" );

Though as pointed out in the comments, bear in mind qDebug messages are removed if QT_NO_DEBUG_OUTPUT is defined

If you need stdout you could try something like this (as Kyle Strand has pointed out):

QTextStream& qStdOut()
{
    static QTextStream ts( stdout );
    return ts;
}

You could then call as follows:

qStdOut() << "std out!";

Use the following code:

string  strtest ="PRASHANT";
strtest.First().ToString().ToUpper() + strtest.Remove(0, 1).ToLower();

See https://developer.mozilla.org/en/DOM/document.cookie for more documentation:

 setItem: function (sKey, sValue, vEnd, sPath, sDomain, bSecure) {  
     if (!sKey || /^(?:expires|max\-age|path|domain|secure)$/.test(sKey)) { return; }  
     var sExpires = "";  
     if (vEnd) {  
       switch (typeof vEnd) {  
         case "number": sExpires = "; max-age=" + vEnd; break;  
         case "string": sExpires = "; expires=" + vEnd; break;  
         case "object": if (vEnd.hasOwnProperty("toGMTString")) { sExpires = "; expires=" + vEnd.toGMTString(); } break;  
       }  
     }  
     document.cookie = escape(sKey) + "=" + escape(sValue) + sExpires + (sDomain ? "; domain=" + sDomain : "") + (sPath ? "; path=" + sPath : "") + (bSecure ? "; secure" : "");  
   }

Do

setTimeout(
    function() {
        this.setState({ position: 1 });
    }
    .bind(this),
    3000
);

Otherwise, you are passing the result of setState to setTimeout.

You can also use ES6 arrow functions to avoid the use of this keyword:

setTimeout(
  () => this.setState({ position: 1 }), 
  3000
);

Regarding the internal structure of a Python long, check sys.int_info (or sys.long_info for Python 2.7).

>>> import sys
>>> sys.int_info
sys.int_info(bits_per_digit=30, sizeof_digit=4)

Python either stores 30 bits into 4 bytes (most 64-bit systems) or 15 bits into 2 bytes (most 32-bit systems). Comparing the actual memory usage with calculated values, I get

>>> import math, sys
>>> a=0
>>> sys.getsizeof(a)
24
>>> a=2**100
>>> sys.getsizeof(a)
40
>>> a=2**1000
>>> sys.getsizeof(a)
160
>>> 24+4*math.ceil(100/30)
40
>>> 24+4*math.ceil(1000/30)
160

There are 24 bytes of overhead for 0 since no bits are stored. The memory requirements for larger values matches the calculated values.

If your numbers are so large that you are concerned about the 6.25% unused bits, you should probably look at the gmpy2 library. The internal representation uses all available bits and computations are significantly faster for large values (say, greater than 100 digits).

Are you looking for the binary conversion?

double result = Double.longBitsToDouble(15552451L);

This will give you the double with the same bit pattern as the long literal.

Binary or hexadecimal literals will come in handy, here. Here are some examples.

double nan = Double.longBitsToDouble(0xfff0000000000001L);
double positiveInfinity = Double.longBitsToDouble(0x7ff0000000000000L);
double positiveInfinity = Double.longBitsToDouble(0xfff0000000000000L);

(See Double.longBitsToDouble(long))

You also can get the long back with

long bits = Double.doubleToRawLongBits(Double.NaN);

(See Double.doubleToRawLongBits(double))

This might work out for you depending on which language you are using:

(?<=Object Name:).*

It's a positive lookbehind assertion. More information could be found here.

It won't work with JavaScript though. In your comment I read that you're using it for logstash. If you are using GROK parsing for logstash then it would work. You can verify it yourself here:

Asynchronous programming is slightly more complicated because the consequence of making a request is encapsulated in a function instead of following the request statement. But the realtime behavior that the user experiences can be significantly better because they will not see a sluggish server or sluggish network cause the browser to act as though it had crashed. Synchronous programming is disrespectful and should not be employed in applications which are used by people.

Douglas Crockford (YUI Blog)

Alright, buckle your seats, because it's going to be a bumpy ride. More and more people ask about loading scripts dynamically via javascript, it seems to be a hot topic.

The main reasons why this became so popular are:

• client-side modularity
• easier dependency management
• error handling
• performance advantages

About modularity: it is obvious that managing client-side dependencies should be handled right on the client-side. If a certain object, module or library is needed we just ask for it and load it dynamically.

Error handling: if a resource fails we still get the chance to block only the parts that depend on the affected script, or maybe even give it another try with some delay.

Performance has become a competitive edge between websites, it is now a search ranking factor. What dynamic scripts can do is mimic asynchronous behavior as opposed to the default blocking way of how browsers handle scripts. Scripts block other resources, scripts block further parsing of the HTML document, scripts block the UI. Now with dynamic script tags and its cross-browser alternatives you can do real asynchronous requests, and execute dependent code only when they are available. Your scripts will load in-parallel even with other resources and the rendering will be flawless.

The reason why some people stick to synchronous scripting is because they are used to it. They think it is the default way, it is the easier way, and some may even think it is the only way.

But the only thing we should care about when this needs to be decided concerning an applications's design is the end-user experience. And in this area asynchronous cannot be beaten. The user gets immediate responses (or say promises), and a promise is always better than nothing. A blank screen scares people. Developers shouldn't be lazy to enhance perceived performance.

And finally some words about the dirty side. What you should do in order to get it working across browsers:

1. learn to think asynchronously
2. organize your code to be modular
3. organize your code to handle errors and edge cases well
4. enhance progressively
5. always take care of the right amount of feedback

There is no Javascript API to send ping frames or receive pong frames. This is either supported by your browser, or not. There is also no API to enable, configure or detect whether the browser supports and is using ping/pong frames. There was discussion about creating a Javascript ping/pong API for this. There is a possibility that pings may be configurable/detectable in the future, but it is unlikely that Javascript will be able to directly send and receive ping/pong frames.

However, if you control both the client and server code, then you can easily add ping/pong support at a higher level. You will need some sort of message type header/metadata in your message if you don't have that already, but that's pretty simple. Unless you are planning on sending pings hundreds of times per second or have thousands of simultaneous clients, the overhead is going to be pretty minimal to do it yourself.

There are several possibilities.

• firewall, iptables configuration
• apache listen address / port

More information is needed about your configuration. What distro are you using? Can you connect via 127.0.0.1?

If the issue is with the firewall/iptables, you can add the following lines to /etc/sysconfig/iptables:

-A INPUT -p tcp -m tcp --dport 80 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 443 -j ACCEPT

(Second line is only needed for https)

Make sure this is above any lines that would globally restrict access, like the following:

-A INPUT -j REJECT --reject-with icmp-host-prohibited

Tested on CentOS 6.3

And finally

service iptables restart

Using regular expressions is costly in terms of performance. Trying to parse string as a long value is inefficient and unreliable, and may be not what you need.

What I suggest is to simply check if each character is a digit, what can be efficiently done using Java 8 lambda expressions:

boolean isNumeric = someString.chars().allMatch(x -> Character.isDigit(x));

Usefull fallback here: https://developer.mozilla.org/en-US/docs/Web/Events/MozOrientation

function orientationhandler(evt){


  // For FF3.6+
  if (!evt.gamma && !evt.beta) {
    evt.gamma = -(evt.x * (180 / Math.PI));
    evt.beta = -(evt.y * (180 / Math.PI));
  }

  // use evt.gamma, evt.beta, and evt.alpha 
  // according to dev.w3.org/geo/api/spec-source-orientation


}

window.addEventListener('deviceorientation',  orientationhandler, false);
window.addEventListener('MozOrientation',     orientationhandler, false);

May I add something. If you are using currency you should use Scale(2), and you should probably figure out a round method.

drop returns a new array so that is why it choked in the og post; I had a similar requirement to rename some column headers and deleted some rows due to an ill formed csv file converted to Dataframe, so after reading this post I used:

newList = pd.DataFrame(newList)
newList.columns = ['Area', 'Price']
print(newList)
# newList = newList.drop(0)
# newList = newList.drop(len(newList))
newList = newList[1:-1]
print(newList)

and it worked great, as you can see with the two commented out lines above I tried the drop.() method and it work but not as kool and readable as using [n:-n], hope that helps someone, thanks.

There is no single magic function to force a frame to a minimum or fixed size. However, you can certainly force the size of a frame by giving the frame a width and height. You then have to do potentially two more things: when you put this window in a container you need to make sure the geometry manager doesn't shrink or expand the window. Two, if the frame is a container for other widget, turn grid or pack propagation off so that the frame doesn't shrink or expand to fit its own contents.

Note, however, that this won't prevent you from resizing a window to be smaller than an internal frame. In that case the frame will just be clipped.

import Tkinter as tk

root = tk.Tk()
frame1 = tk.Frame(root, width=100, height=100, background="bisque")
frame2 = tk.Frame(root, width=50, height = 50, background="#b22222")

frame1.pack(fill=None, expand=False)

You can use your own code. You don't need to use the looping structure, if you don't want to use the looping structure as you said above. Only you have to focus to remove space or trim the String of the list.

If you are using java8 you can simply trim the String using the single line of the code:

myList = myList.stream().map(String :: trim).collect(Collectors.toList());

The importance of the above line is, in the future, you can use a List or set as well. Now you can use your own code:

if(myList.contains("A")){
    //true
}else{
    // false
}

maytham-???i???, you can use this code to simulate input of file:

System.setIn(new FileInputStream("FILE_NAME"));

Or send file name as parameter and then put it into FileInputStream:

System.setIn(new FileInputStream(args[0]));

Another issue you may run into with self signed test certs is this:

java.io.IOException: HTTPS hostname wrong: should be ...

This error occurs when you are trying to access a HTTPS url. You might have already installed the server certificate to your JRE's keystore. But this error means that the name of the server certificate does not match with the actual domain name of the server that is mentioned in the URL. This normally happens when you are using a non CA issued certificate.

This example shows how to write a HttpsURLConnection DefaultHostnameVerifier that ignore the certificates server name:

Search for   or only nbsp - did you try this?

You can just use .animate() the scrollTop property, like this:

$("html, body").animate({ scrollTop: "300px" });

DT[order(-x)] works as expected. I have data.table version 1.9.4. Maybe this was fixed in a recent version.
Also, I suggest the setorder(DT, -x) syntax in keeping with the set* commands like setnames, setkey

You can convert ZonedDateTime to an instant, which you can use directly with Date.

Date.from(java.time.ZonedDateTime.now().toInstant());

Here you have an example working on py2.6 and py3.2:

from scipy.stats import norm
import matplotlib.mlab as mlab
import matplotlib.pyplot as plt

# read data from a text file. One number per line
arch = "test/Log(2)_ACRatio.txt"
datos = []
for item in open(arch,'r'):
    item = item.strip()
    if item != '':
        try:
            datos.append(float(item))
        except ValueError:
            pass

# best fit of data
(mu, sigma) = norm.fit(datos)

# the histogram of the data
n, bins, patches = plt.hist(datos, 60, normed=1, facecolor='green', alpha=0.75)

# add a 'best fit' line
y = mlab.normpdf( bins, mu, sigma)
l = plt.plot(bins, y, 'r--', linewidth=2)

#plot
plt.xlabel('Smarts')
plt.ylabel('Probability')
plt.title(r'$\mathrm{Histogram\ of\ IQ:}\ \mu=%.3f,\ \sigma=%.3f$' %(mu, sigma))
plt.grid(True)

plt.show()

There are a few ways. One of the simplest is to create a my-paths.pth file (as described here). This is just a file with the extension .pth that you put into your system site-packages directory. On each line of the file you put one directory name, so you can put a line in there with /path/to/the/ and it will add that directory to the path.

You could also use the PYTHONPATH environment variable, which is like the system PATH variable but contains directories that will be added to sys.path. See the documentation.

Note that no matter what you do, sys.path contains directories not files. You can't "add a file to sys.path". You always add its directory and then you can import the file.

Depends on what you mean by better. This works if your goal is removal of redundancy.

s='foo'
string='%s bar baz %s bar baz %s bar baz' % (3*(s,))

We can completely avoid using the slow Math.pow() and Math.log() methods without sacrificing simplicity since the factor between the units (for example, B, KB, MB, etc.) is 1024 which is 2^10. The Long class has a handy numberOfLeadingZeros() method which we can use to tell which unit the size value falls in.

Key point: Size units have a distance of 10 bits (1024 = 2^10) meaning the position of the highest one bit–or in other words the number of leading zeros–differ by 10 (Bytes = KB*1024, KB = MB*1024, etc.).

Correlation between number of leading zeros and size unit:

# of leading 0's   Size unit
-------------------------------
>53                B (Bytes)
>43                KB
>33                MB
>23                GB
>13                TB
>3                 PB
<=2                EB

The final code:

public static String formatSize(long v) {
    if (v < 1024) return v + " B";
    int z = (63 - Long.numberOfLeadingZeros(v)) / 10;
    return String.format("%.1f %sB", (double)v / (1L << (z*10)), " KMGTPE".charAt(z));
}

Its a simple xml design. It looks like iOS switch, check this below image

You need to create custom_thumb.xml and custom_track.xml

This is my switch,I need a very big switch so added layout_width/layout_height parameter

 <androidx.appcompat.widget.SwitchCompat
        android:id="@+id/swOnOff"
        android:layout_width="@dimen/_200sdp"
        android:layout_marginStart="@dimen/_50sdp"
        android:layout_marginEnd="@dimen/_50sdp"
        android:layout_marginTop="@dimen/_30sdp"
        android:layout_gravity="center"
        app:showText="true"
        android:textSize="@dimen/_20ssp"
        android:fontFamily="@font/opensans_bold"
        app:track="@drawable/custom_track"
        android:thumb="@drawable/custom_thumb"
        android:layout_height="@dimen/_120sdp"/>

Now create custom_thumb.xml

<?xml version="1.0" encoding="utf-8"?>
<selector
    xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="false">

            <stroke android:width="1dp"

                android:color="#34c759"/>
        </shape>
    </item>
</selector>

Now create custom_track.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="false">
        <shape android:shape="rectangle">

The solution above not working for the latest version on PostgreSQL. I found this way to convert epoch time being stored in number and int column type is on PostgreSQL 13:

SELECT TIMESTAMP 'epoch' + (<table>.field::int) * INTERVAL '1 second' as started_on from <table>;

For more detail explanation, you can see here https://www.yodiw.com/convert-epoch-time-to-timestamp-in-postgresql/#more-214

In similar situations, I've done well by putting something like the following into /etc/rc.local:

cd /path/to/my/script
./my_script.py &
cd -
echo `date +%Y-%b-%d_%H:%M:%S` > /tmp/ran_rc_local  # check that rc.local ran

This has worked on multiple versions of Fedora and on Ubuntu 14.04 LTS, for both python and perl scripts.

netcat (nc.exe) is the right tool. I have a feeling that any tool that does what you want it to do will have exactly the same problem with your antivirus software. Just flag this program as "OK" in your antivirus software (how you do this will depend on what type of antivirus software you use).

Of course you will also need to configure your sysadmin to accept that you're not trying to do anything illegal...

I also implement it via css background property. It works healty in any width value.

.navbar-brand{
    float:left;
    height:50px;
    padding:15px 15px;
    font-size:18px;
    line-height:20px;
    background-image: url("../images/logo.png");
    background-repeat: no-repeat;
    background-position: left center
}

I had a similar problem. It turned out that I had an alias defined for python like so:

alias python=/usr/bin/python3

Apparently virtualenv does not check or update your aliases.

So the solution for me was to remove the alias:

unalias python

Now when I run python, I get the one from the virtual environment. Problem solved.

FYI, this is using Angularfire so it may vary a bit for a different service or other use but should solve the same isse $http has. I had this same issue only solution that fit for me the best was to combine all services/factories into a single promise on the scope. On each route/view that needed these services/etc to be loaded I put any functions that require loaded data inside the controller function i.e. myfunct() and the main app.js on run after auth i put

myservice.$loaded().then(function() {$rootScope.myservice = myservice;});

and in the view I just did

ng-if="myservice" ng-init="somevar=myfunct()"

in the first/parent view element/wrapper so the controller can run everything inside

myfunct()

without worrying about async promises/order/queue issues. I hope that helps someone with the same issues I had.

Your header file Hash.h declares "what class hash should look like", but not its implementation, which is (presumably) in some other source file we'll call Hash.cpp. By including the header in your main file, the compiler is informed of the description of class Hash when compiling the file, but not how class Hash actually works. When the linker tries to create the entire program, it then complains that the implementation (toHash::insert(int, char)) cannot be found.

The solution is to link all the files together when creating the actual program binary. When using the g++ frontend, you can do this by specifying all the source files together on the command line. For example:

g++ -o main Hash.cpp main.cpp

will create the main program called "main".

for me following worked, just ran these command one by one

git pull -r origin master

git push -f origin your_branch

Try this

var Regex='/^[^a-zA-Z]*$/';

 if(Regex.test(word))
 {
 //...
 }

I think it will be working for you.

Your and should be a && in the where clause.

where epl.DepartAirportAfter >  sd.UTCDepartureTime 
and epl.ArriveAirportBy > sd.UTCArrivalTime

should be

where epl.DepartAirportAfter >  sd.UTCDepartureTime 
&& epl.ArriveAirportBy > sd.UTCArrivalTime

function sample() {
    alert("This is sample function");
}

$(function() {
    $("#button").click(function() {
        setTimeout(sample, 2000);
    });

});

jsFiddle.

If you want to encapsulate sample() there, wrap the whole thing in a self invoking function (function() { ... })().

Jezus, all this programming for just an index restart... Perhaps I'm an idiot, but for pre-oracle 12 (which has a restart feature), what is wrong with a simpel:

drop sequence blah;
create sequence blah 

?

Try

myString = 'abcabc'
myString.find('a')

This will give you the index!!!

By now, cloud bitbucket (I'm not sure which version) allows to revert a commit from the file system as follows (I do not see how to revert from the Bitbucket interface in the Chrome browser).

-backup your entire directory to secure the changes you inadvertently committed

-select checked out directory

-right mouse button: tortoise git menu

-repo-browser (the menu option 'revert' only undoes the uncommited changes)

-press the HEAD button

-select the uppermost line (the last commit)

-right mouse button: revert change by this commit

-after it undid the changes on the file system, press commit

-this updates GIT with a message 'Revert (your previous message). This reverts commit so-and-so'

-select 'commit and push'.

You need to set oracle to listen on all ip addresses (by default, it listens only to localhost connections.)

Step 1 - Edit listener.ora

This file is located in:

• Windows: %ORACLE_HOME%\network\admin\listener.ora.
• Linux: $ORACLE_HOME/network/admin/listener.ora

Replace localhost with 0.0.0.0

# ...

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 0.0.0.0)(PORT = 1521))
    )
  )

# ...

Step 2 - Restart Oracle services

• Windows: WinKey + r

  services.msc
  

• Linux (CentOs):

  sudo systemctl restart oracle-xe
  

On toolbar -> Help Menu -> Show log in explorer.

It opens log folder, where you can find all logs

If you're on OSX you can also find it your keychain. Your developer and distribution certificates have your Team ID in them.

Applications -> Utilities -> Keychain Access.

Under the 'login' Keychain, go into the 'Certificates' category.

Scroll to find your development or distribution certificate. They will read:

iPhone Distribution: Team Name (certificate id)

or

iPhone Developer: Team Name (certificate id)

Simply double-click on the item, and the

"Organizational Unit"

is the "Team ID"

Note that this is the only way to find your

"Personal team" ID

You can not find the "Personal team" ID on the Apple web interface.

For example, if you are automating a build from say Unity, during development you'll want it to appear in Xcode as your "Personal team" - this is the only way to get that value.

With a Microsoft compiler[1], static variables that are not int-like can also be defined in a header file, but outside of the class declaration, using the Microsoft specific __declspec(selectany).

class A
{
    static B b;
}

__declspec(selectany) A::b;

Note that I'm not saying this is good, I just say it can be done.

[1] These days, more compilers than MSC support __declspec(selectany) - at least gcc and clang. Maybe even more.

You could do an SQLDump of the database (and its data) then search that file.

Make sure you follow the language definition for JSON. In your second example, the section:

"labs":[{
    ""
}]

Is invalid since an object must be composed of zero or more key-value pairs "a" : "b", where "b" may be any valid value. Some parsers may automatically interpret { "" } to be { "" : null }, but this is not a clearly defined case.

Also, you are using a nested array of objects [{}] quite a bit. I would only do this if:

1. There is no good "identifier" string for each object in the array.
2. There is some clear reason for having an array over a key-value for that entry.

Windows imposes a memory limit per process, you can see what it is for each version here

See:

User-mode virtual address space for each 64-bit process; With IMAGE_FILE_LARGE_ADDRESS_AWARE set (default): x64: 8 TB Intel IPF: 7 TB 2 GB with IMAGE_FILE_LARGE_ADDRESS_AWARE cleared

I created an angularjs directive using @Russ's and @Alex's answers

Could be interesting in 2014 and beyond :P

html

<div ng-app="croppy">
  <cropped-image src="http://placehold.it/200x200" width="100" height="100"></cropped-image>
</div>

js

angular.module('croppy', [])
  .directive('croppedImage', function () {
      return {
          restrict: "E",
          replace: true,
          template: "<div class='center-cropped'></div>",
          link: function(scope, element, attrs) {
              var width = attrs.width;
              var height = attrs.height;
              element.css('width', width + "px");
              element.css('height', height + "px");
              element.css('backgroundPosition', 'center center');
              element.css('backgroundRepeat', 'no-repeat');
              element.css('backgroundImage', "url('" + attrs.src + "')");
          }
      }
  });

On Android API Level 28, I simply ensure that I set up my LinearLayoutManager and RecyclerView.Adapter in my Fragment#onCreateView method, and everything Just Worked™?. I didn't need to do any onSaveInstanceState or onRestoreInstanceState work.

Eugen Pechanec's answer explains why this works.

The deduplication (to select the max T1) and the aggregation need to be done as distinct steps. I've used a CTE since I think this makes it clearer:

;WITH sumCTE
AS
(
    SELECT  Rel.t2ID, SUM(Price) price
    FROM    @t1         AS T1
    JOIN    @relation   AS Rel 
    ON      Rel.t1ID=T1.ID
    GROUP 
    BY      Rel.t2ID
)
,maxCTE
AS
(
    SELECT  Rel.t2ID, Rel.t1ID, 
            ROW_NUMBER()OVER(Partition By Rel.t2ID Order By Price DESC)As PriceList
    FROM    @t1         AS T1
    JOIN    @relation   AS Rel 
    ON      Rel.t1ID=T1.ID
)
SELECT T2.ID AS T2ID
,T2.Name as T2Name
,T2.Orders
,T1.ID AS T1ID
,T1.Name As T1Name
,sumT1.Price
FROM    @t2 AS T2
JOIN    sumCTE AS sumT1
ON      sumT1.t2ID = t2.ID
JOIN    maxCTE AS maxT1
ON      maxT1.t2ID = t2.ID
JOIN    @t1 AS T1
ON      T1.ID = maxT1.t1ID
WHERE   maxT1.PriceList = 1

Make sure that the actual .vim file is in ~/.vim/plugin/

Consider using a higher dimensional datastructure (a Panel), rather than storing an array in your column:

In [11]: p = pd.Panel({'df': df, 'csc': csc})

In [12]: p.df
Out[12]: 
   0  1  2
0  1  2  3
1  4  5  6
2  7  8  9

In [13]: p.csc
Out[13]: 
   0  1  2
0  0  1  0
1  0  0  1
2  1  0  0

Look at cross-sections etc, etc, etc.

In [14]: p.xs(0)
Out[14]: 
   csc  df
0    0   1
1    1   2
2    0   3

See the docs for more on Panels.

To add a project within a solution, just open the Team Explorer window and go to Changes. Then, under Untracked Files, click on View options and select Switch to Tree View (unless it is already in tree view), right click on the project root folder, and select Add.

So I get you are using Eclipse with the M2E plugin. Try to update your Maven configuration : In the Project Explorer, right-click on the project, Maven -> Update project.

If the problem still remains, try to clean your project: right-click on your pom.xml, Run as -> Maven build (the second one). Enter "clean package" in the Goals fields. Check the Skip Tests box. Click on the Run button.

Edit: For your new problem, you need to add Spring MVC to your pom.xml. Add something like the following:

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-webmvc</artifactId>
    <version>4.0.0.RELEASE</version>
</dependency>

Maybe you have to change the version to match the version of your Spring framework. Take a look here:

http://mvnrepository.com/artifact/org.springframework/spring-webmvc

There's one more issue you might need to address if you are using the Windows 2008 Server with IIS7. The server might report the following error:

Microsoft Office Excel cannot access the file 'c:\temp\test.xls'. There are several possible reasons:

• The file name or path does not exist.
• The file is being used by another program.
• The workbook you are trying to save has the same name as a currently open workbook.

The solution is posted here (look for the text posted by user Ogawa): http://social.msdn.microsoft.com/Forums/en-US/innovateonoffice/thread/b81a3c4e-62db-488b-af06-44421818ef91?prof=required

On a Windows platform,

1. Find your my.ini configuration file.
2. In my.ini go to the [mysqld] section.
3. Add explicit_defaults_for_timestamp=true without quotes and save the change.
4. Start mysqld

This worked for me (windows 7 Ultimate 32bit)
