Programs & Examples On #Ticker

$ pip install pickle5

import pickle5 as pickle

pb = pickle.PickleBuffer(b"foo")
data = pickle.dumps(pb, protocol=5)
assert pickle.loads(data) == b"foo"

This package backports all features and APIs added in the pickle module in Python 3.8.3, including the PEP 574 additions. It should work with Python 3.5, 3.6 and 3.7.

Basic usage is similar to the pickle module, except that the module to be imported is pickle5:

Simple plot,

you can use:

df.plot(x='Date',y='adj_close')

Or you can set the index to be Date beforehand, then it's easy to plot the column you want:

df.set_index('Date', inplace=True)
df['adj_close'].plot()

If you want a chart with one series by ticker on it

You need to groupby before:

df.set_index('Date', inplace=True)
df.groupby('ticker')['adj_close'].plot(legend=True)

If you want a chart with individual subplots:

grouped = df.groupby('ticker')

ncols=2
nrows = int(np.ceil(grouped.ngroups/ncols))

fig, axes = plt.subplots(nrows=nrows, ncols=ncols, figsize=(12,4), sharey=True)

for (key, ax) in zip(grouped.groups.keys(), axes.flatten()):
    grouped.get_group(key).plot(ax=ax)

ax.legend()
plt.show()

Steps:

1. Under General ? Signing
2. Uncheck: Automatically manage signing
3. Select Import Provisioning

For those who are looking for the quick one-liner:

plt.gca().set_yticklabels(['{:.0f}%'.format(x*100) for x in plt.gca().get_yticks()]) 

Or if you are using Latex as the axis text formatter, you have to add one backslash '\'

plt.gca().set_yticklabels(['{:.0f}\%'.format(x*100) for x in plt.gca().get_yticks()]) 

A workaround is to transpose the DataFrame and iterate over the rows.

for column_name, column in df.transpose().iterrows():
    print column_name

You can try to make your own drawable for the hamburger icon like this.

<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="24dp"
    android:height="24dp"
    android:viewportHeight="24.0"
    android:viewportWidth="24.0">
    <path
        android:fillColor="#ffffff"
        android:pathData="M3,18h18v-2L3,16v2zM3,13h18v-2L3,11v2zM3,6v2h18L21,6L3,6z" />
</vector>

Then in your fragment/activity,

getSupportActionBar().setHomeAsUpIndicator(R.drawable.as_above);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);

A few comments:

• The Nyquist frequency is half the sampling rate.
• You are working with regularly sampled data, so you want a digital filter, not an analog filter. This means you should not use analog=True in the call to butter, and you should use scipy.signal.freqz (not freqs) to generate the frequency response.
• One goal of those short utility functions is to allow you to leave all your frequencies expressed in Hz. You shouldn't have to convert to rad/sec. As long as you express your frequencies with consistent units, the scaling in the utility functions takes care of the normalization for you.

Here's my modified version of your script, followed by the plot that it generates.

import numpy as np
from scipy.signal import butter, lfilter, freqz
import matplotlib.pyplot as plt


def butter_lowpass(cutoff, fs, order=5):
    nyq = 0.5 * fs
    normal_cutoff = cutoff / nyq
    b, a = butter(order, normal_cutoff, btype='low', analog=False)
    return b, a

def butter_lowpass_filter(data, cutoff, fs, order=5):
    b, a = butter_lowpass(cutoff, fs, order=order)
    y = lfilter(b, a, data)
    return y


# Filter requirements.
order = 6
fs = 30.0       # sample rate, Hz
cutoff = 3.667  # desired cutoff frequency of the filter, Hz

# Get the filter coefficients so we can check its frequency response.
b, a = butter_lowpass(cutoff, fs, order)

# Plot the frequency response.
w, h = freqz(b, a, worN=8000)
plt.subplot(2, 1, 1)
plt.plot(0.5*fs*w/np.pi, np.abs(h), 'b')
plt.plot(cutoff, 0.5*np.sqrt(2), 'ko')
plt.axvline(cutoff, color='k')
plt.xlim(0, 0.5*fs)
plt.title("Lowpass Filter Frequency Response")
plt.xlabel('Frequency [Hz]')
plt.grid()


# Demonstrate the use of the filter.
# First make some data to be filtered.
T = 5.0         # seconds
n = int(T * fs) # total number of samples
t = np.linspace(0, T, n, endpoint=False)
# "Noisy" data.  We want to recover the 1.2 Hz signal from this.
data = np.sin(1.2*2*np.pi*t) + 1.5*np.cos(9*2*np.pi*t) + 0.5*np.sin(12.0*2*np.pi*t)

# Filter the data, and plot both the original and filtered signals.
y = butter_lowpass_filter(data, cutoff, fs, order)

plt.subplot(2, 1, 2)
plt.plot(t, data, 'b-', label='data')
plt.plot(t, y, 'g-', linewidth=2, label='filtered data')
plt.xlabel('Time [sec]')
plt.grid()
plt.legend()

plt.subplots_adjust(hspace=0.35)
plt.show()

A subtle alternative to MaxNoe's answer where you aren't explicitly setting the ticks but instead setting the cadence.

import matplotlib.pyplot as plt
from matplotlib.ticker import (AutoMinorLocator, MultipleLocator)

fig, ax = plt.subplots(figsize=(10, 8))

# Set axis ranges; by default this will put major ticks every 25.
ax.set_xlim(0, 200)
ax.set_ylim(0, 200)

# Change major ticks to show every 20.
ax.xaxis.set_major_locator(MultipleLocator(20))
ax.yaxis.set_major_locator(MultipleLocator(20))

# Change minor ticks to show every 5. (20/4 = 5)
ax.xaxis.set_minor_locator(AutoMinorLocator(4))
ax.yaxis.set_minor_locator(AutoMinorLocator(4))

# Turn grid on for both major and minor ticks and style minor slightly
# differently.
ax.grid(which='major', color='#CCCCCC', linestyle='--')
ax.grid(which='minor', color='#CCCCCC', linestyle=':')

You need a ResourceLink in your META-INF/context.xml file to make the global resource available to the web application.

 <ResourceLink name="jdbc/mydb"
             global="jdbc/mydb"
              type="javax.sql.DataSource" />

There is a way to catch the error directly in the except clause with ConnectionResetError, better to isolate the right error. This example also catches the timeout.

from urllib.request import urlopen 
from socket import timeout

url = "http://......"
try: 
    string = urlopen(url, timeout=5).read()
except ConnectionResetError:
    print("==> ConnectionResetError")
    pass
except timeout: 
    print("==> Timeout")
    pass

From the oracle documentation, the below query explains it better

INSERT INTO tbl_temp2 (fld_id)
SELECT tbl_temp1.fld_order_id
FROM tbl_temp1 WHERE tbl_temp1.fld_order_id > 100;

You can read this link

Your query would be as follows

//just the concept    
    INSERT INTO quotedb
    (COLUMN_NAMES) //seperated by comma
    SELECT COLUMN_NAMES FROM tickerdb,quotedb WHERE quotedb.ticker = tickerdb.ticker

Note: Make sure the columns in insert and select are in right position as per your requirement

Hope this helps!

Try to execute the procedure like this,

var c refcursor;
execute pkg_name.get_user('14232', '15', 'TDWL', 'SA', 1, :c);
print c;

This is what I came up to when trying to copy-paste excel ranges with it's sizes and cell groups. It might be a little too specific for my problem but...:

As from the answer from BrianC use the YQL console. But after selecting the "Show Community Tables" go to the bottom of the tables list and expand yahoo where you find plenty of yahoo.finance tables:

Stock Quotes:

• yahoo.finance.quotes
• yahoo.finance.historicaldata

Fundamental analysis:

• yahoo.finance.keystats
• yahoo.finance.balancesheet

|= reads the same way as +=.

notification.defaults |= Notification.DEFAULT_SOUND;

is the same as

notification.defaults = notification.defaults | Notification.DEFAULT_SOUND;

where | is the bit-wise OR operator.

All operators are referenced here.

A bit-wise operator is used because, as is frequent, those constants enable an int to carry flags.

If you look at those constants, you'll see that they're in powers of two :

public static final int DEFAULT_SOUND = 1;
public static final int DEFAULT_VIBRATE = 2; // is the same than 1<<1 or 10 in binary
public static final int DEFAULT_LIGHTS = 4; // is the same than 1<<2 or 100 in binary

So you can use bit-wise OR to add flags

int myFlags = DEFAULT_SOUND | DEFAULT_VIBRATE; // same as 001 | 010, producing 011

so

myFlags |= DEFAULT_LIGHTS;

simply means we add a flag.

And symmetrically, we test a flag is set using & :

boolean hasVibrate = (DEFAULT_VIBRATE & myFlags) != 0;

This topic is well covered but I still would like to propose another approach in a slightly different philosophy.

It is a bit more complex to set-up but it allow (in my opinion) a bit more flexibility. For example, one can play with the respective ratios of each subplots / colorbar:

import matplotlib.pyplot as plt
import numpy as np
from matplotlib.gridspec import GridSpec

# Define number of rows and columns you want in your figure
nrow = 2
ncol = 3

# Make a new figure
fig = plt.figure(constrained_layout=True)

# Design your figure properties
widths = [3,4,5,1]
gs = GridSpec(nrow, ncol + 1, figure=fig, width_ratios=widths)

# Fill your figure with desired plots
axes = []
for i in range(nrow):
    for j in range(ncol):
        axes.append(fig.add_subplot(gs[i, j]))
        im = axes[-1].pcolormesh(np.random.random((10,10)))

# Shared colorbar    
axes.append(fig.add_subplot(gs[:, ncol]))
fig.colorbar(im, cax=axes[-1])

plt.show()

See below code. I am using that and it is opening my HomeActivity.

    NotificationManager notificationManager = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);
    Notification notification = new Notification(icon, message, when);

    Intent notificationIntent = new Intent(context, HomeActivity.class);

    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
            | Intent.FLAG_ACTIVITY_SINGLE_TOP);

    PendingIntent intent = PendingIntent.getActivity(context, 0,
            notificationIntent, 0);

    notification.setLatestEventInfo(context, title, message, intent);
    notification.flags |= Notification.FLAG_AUTO_CANCEL;
    notificationManager.notify(0, notification);

import vs. include

The primary purpose of an import is to import a namespace. A more common use of the XSD import statement is to import a namespace which appears in another file. You might be gathering the namespace information from the file, but don't forget that it's the namespace that you're importing, not the file (don't confuse an import statement with an include statement).

Another area of confusion is how to specify the location or path of the included .xsd file: An XSD import statement has an optional attribute named schemaLocation but it is not necessary if the namespace of the import statement is at the same location (in the same file) as the import statement itself.

When you do chose to use an external .xsd file for your WSDL, the schemaLocation attribute becomes necessary. Be very sure that the namespace you use in the import statement is the same as the targetNamespace of the schema you are importing. That is, all 3 occurrences must be identical:

WSDL:

xs:import namespace="urn:listing3" schemaLocation="listing3.xsd"/>

XSD:

<xsd:schema targetNamespace="urn:listing3"
            xmlns:xsd="http://www.w3.org/2001/XMLSchema"> 

Another approach to letting know the WSDL about the XSD is through Maven's pom.xml:

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>xmlbeans-maven-plugin</artifactId>
  <executions>
    <execution>
      <id>generate-sources-xmlbeans</id>
      <phase>generate-sources</phase>
      <goals>
    <goal>xmlbeans</goal>
      </goals>
    </execution>
  </executions>
  <version>2.3.3</version>
  <inherited>true</inherited>
  <configuration>
    <schemaDirectory>${basedir}/src/main/xsd</schemaDirectory>
  </configuration>
</plugin>

You can read more on this in this great IBM article. It has typos such as xsd:import instead of xs:import but otherwise it's fine.

Separate with commas:

http://localhost:8080/MovieDB/GetJson?name=Actor1,Actor2,Actor3&startDate=20120101&endDate=20120505

or:

http://localhost:8080/MovieDB/GetJson?name=Actor1&name=Actor2&name=Actor3&startDate=20120101&endDate=20120505

or:

http://localhost:8080/MovieDB/GetJson?name[0]=Actor1&name[1]=Actor2&name[2]=Actor3&startDate=20120101&endDate=20120505

Either way, your method signature needs to be:

@RequestMapping(value = "/GetJson", method = RequestMethod.GET) 
public void getJson(@RequestParam("name") String[] ticker, @RequestParam("startDate") String startDate, @RequestParam("endDate") String endDate) {
   //code to get results from db for those params.
 }

Why write custom jQuery code for Marquee... just use a plugin for jQuery - marquee() and use it like in the example below:

First include :

<script type='text/javascript' src='//cdn.jsdelivr.net/jquery.marquee/1.3.1/jquery.marquee.min.js'></script>

and then:

//proporcional speed counter (for responsive/fluid use)
var widths = $('.marquee').width()
var duration = widths * 7;

$('.marquee').marquee({
    //speed in milliseconds of the marquee
    duration: duration, // for responsive/fluid use
    //duration: 8000, // for fixed container
    //gap in pixels between the tickers
    gap: $('.marquee').width(),
    //time in milliseconds before the marquee will start animating
    delayBeforeStart: 0,
    //'left' or 'right'
    direction: 'left',
    //true or false - should the marquee be duplicated to show an effect of continues flow
    duplicated: true
});

If you can make it simpler and better I dare you all people :). Don't make your life more difficult than it should be. More about this plugin and its functionalities at: http://aamirafridi.com/jquery/jquery-marquee-plugin

Check this: How to maximize a plt.show() window using Python

The command is different depending on which backend you use. I find that this is the best way to make sure the saved pictures have the same scaling as what I view on my screen.

Since I use Canopy with the QT backend:

pylab.get_current_fig_manager().window.showMaximized()

I then call savefig() as required with an increased DPI per silvado's answer.

In Windows Vista and later the HTTP WCF service stuff would cause the exception you mentioned because a restricted account does not have right for that. That is the reason why it worked when you ran it as administrator.

Every sensible developer must use a RESTRICTED account rather than as an Administrator, yet many people go the wrong way and that is precisely why there are so many applications out there that DEMAND admin permissions when they are not really required. Working the lazy way results in lazy solutions. I hope you still work in a restricted account (my congratulations).

There is a tool out there (from 2008 or so) called NamespaceManagerTool if I remember correctly that is supposed to grant the restricted user permissions on these service URLs that you define for WCF. I haven't used that though...

Prior to PHP 7, the session_start() function did not directly accept any configuration options. Now you can do it this way

<?php
// This sends a persistent cookie that lasts a day.
session_start([
    'cookie_lifetime' => 86400,
]);
?>

Reference: https://php.net/manual/en/function.session-start.php#example-5976

i wouldn't do it this way

I'd use name arrays in the form elements

so i'd get the layout

$_POST['field'][0]['name'] = 'value';
$_POST['field'][0]['price'] = 'value';
$_POST['field'][1]['name'] = 'value';
$_POST['field'][1]['price'] = 'value';

then you could do an array slice to get the amount you need

There is a nice C# wrapper for the Yahoo.Finance API at http://code.google.com/p/yahoo-finance-managed/ that will get you there. Unfortunately there is no direct way to download the ticker list but the following creates the list by iterating through the alphabetical groups:

        AlphabeticIDIndexDownload dl1 = new AlphabeticIDIndexDownload();
        dl1.Settings.TopIndex = null;
        Response<AlphabeticIDIndexResult> resp1 = dl1.Download();

        writeStream.WriteLine("Id|Isin|Name|Exchange|Type|Industry");

        foreach (var alphabeticalIndex in resp1.Result.Items)
        {
            AlphabeticalTopIndex topIndex = (AlphabeticalTopIndex) alphabeticalIndex;
            dl1.Settings.TopIndex = topIndex;
            Response<AlphabeticIDIndexResult> resp2 = dl1.Download();

            foreach (var index in resp2.Result.Items)
            {
                IDSearchDownload dl2 = new IDSearchDownload();
                Response<IDSearchResult> resp3 = dl2.Download(index);


                int i = 0;
                foreach (var item in resp3.Result.Items)
                {
                    writeStream.WriteLine(item.ID + "|" + item.ISIN + "|" + item.Name + "|" + item.Exchange + "|" + item.Type + "|" + item.Industry);
                }

            }
        }

It gave me a list of about 75,000 securities in about 4 mins.

startService(new Intent(this, MyService.class));

Just writing this line was not sufficient for me. Service still did not work. Everything had worked only after registering service at manifest

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >

    ...

    <service
        android:name=".MyService"
        android:label="My Service" >
    </service>
</application>

Seems to me you could've saved some memory by declaring your activity with "implements Handler.Callback"

This worked for me. Each month on X axis

str_month_list = ['January','February','March','April','May','June','July','August','September','October','November','December']
ax.set_xticks(range(0,12))
ax.set_xticklabels(str_month_list)

As said in previous answers the 'normal' way is to add it to a JScrollPane, but sometimes you don't want it to scroll (don't ask me when:)). Then you can add the TableHeader yourself. Like this:

JPanel tablePanel = new JPanel(new BorderLayout());
JTable table = new JTable();
tablePanel.add(table, BorderLayout.CENTER);
tablePanel.add(table.getTableHeader(), BorderLayout.NORTH);

After doing some search i got solution from android developer guide

PendingIntent contentIntent ;
Intent intent = new Intent(this,TestActivity.class);
intent.putExtra("extra","Test");
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);

stackBuilder.addParentStack(ArticleDetailedActivity.class);

contentIntent = stackBuilder.getPendingIntent(0,PendingIntent.FLAG_UPDATE_CURRENT);

To Get Intent extra value in Test Activity class you need to write following code :

 Intent intent = getIntent();
 String extra = intent.getStringExtra("extra") ;

If you had a table that already had a existing constraints based on lets say: name and lastname and you wanted to add one more unique constraint, you had to drop the entire constrain by:

ALTER TABLE your_table DROP CONSTRAINT constraint_name;

Make sure tha the new constraint you wanted to add is unique/ not null ( if its Microsoft Sql, it can contain only one null value) across all data on that table, and then you could re-create it.

ALTER TABLE table_name
ADD CONSTRAINT constraint_name UNIQUE (column1, column2, ... column_n);

This solution seems easy to follow:

public static bool isValidURL(string url) {
    WebRequest webRequest = WebRequest.Create(url);
    WebResponse webResponse;
    try
    {
        webResponse = webRequest.GetResponse();
    }
    catch //If exception thrown then couldn't get response from address
    {
        return false ;
    }
    return true ;
}

Google Finance has an API - you probably have to apply for a developers key, but at least you'd save yourself the hassle of screen-scraping: http://code.google.com/apis/finance/reference.html

Let me help in updating the answers here since new users will find it useful. I believe the aim is to delete the database itself and recreate it using EF Code First approach. 1.Open your project in Visual Studio using the ".sln" extention. 2.Select Server Explorer( it is oftentimes on the left) 3.Select SQL Server Object Explorer. 4.The database you want to delete would be listed under any of the localDB. Right-Click it and select delete.

Here's the XPath approach but with a minimum of XPath jargon.

Regular selection based on element attribute values (for comparison):

// for matching <element class="foo bar baz">...</element> by 'bar'
var things = document.querySelectorAll('[class*="bar"]');
for (var i = 0; i < things.length; i++) {
    things[i].style.outline = '1px solid red';
}

XPath selection based on text within element.

// for matching <element>foo bar baz</element> by 'bar'
var things = document.evaluate('//*[contains(text(),"bar")]',document,null,XPathResult.ORDERED_NODE_SNAPSHOT_TYPE,null);
for (var i = 0; i < things.snapshotLength; i++) {
    things.snapshotItem(i).style.outline = '1px solid red';
}

And here's with case-insensitivity since text is more volatile:

// for matching <element>foo bar baz</element> by 'bar' case-insensitively
var things = document.evaluate('//*[contains(translate(text(),"ABCDEFGHIJKLMNOPQRSTUVWXYZ","abcdefghijklmnopqrstuvwxyz"),"bar")]',document,null,XPathResult.ORDERED_NODE_SNAPSHOT_TYPE,null);
for (var i = 0; i < things.snapshotLength; i++) {
    things.snapshotItem(i).style.outline = '1px solid red';
}

It is not absolutely necessary since it can be done with IFs but it's more readable and also less expensive in run time.

I use it in order to skip an iteration in a loop if the data does not meet some requirements:

# List of times at which git commits were done.
# Formatted in hour, minutes in tuples.
# Note the last one has some fantasy.
commit_times = [(8,20), (9,30), (11, 45), (15, 50), (17, 45), (27, 132)]

for time in commit_times:
    hour = time[0]
    minutes = time[1]

    # If the hour is not between 0 and 24
    # and the minutes not between 0 and 59 then we know something is wrong.
    # Then we don't want to use this value,
    # we skip directly to the next iteration in the loop.
    if not (0 <= hour <= 24 and 0 <= minutes <= 59):
        continue

    # From here you know the time format in the tuples is reliable.
    # Apply some logic based on time.
    print("Someone commited at {h}:{m}".format(h=hour, m=minutes))

Output:

Someone commited at 8:20
Someone commited at 9:30
Someone commited at 11:45
Someone commited at 15:50
Someone commited at 17:45

As you can see, the wrong value did not make it after the continue statement.

User order by with that field, and then do distinct.

ProductOrder.objects.order_by('category').values_list('category', flat=True).distinct()

This is for a string array:

string.Join(delimiter, array);

This is for a List<string>:

string.Join(delimiter, list.ToArray());

And this is for a list of custom objects:

string.Join(delimiter, list.Select(i => i.Boo).ToArray());

Get List of function_schema and function_name...

SELECT
    n.nspname AS function_schema,
    p.proname AS function_name
FROM
    pg_proc p
    LEFT JOIN pg_namespace n ON p.pronamespace = n.oid
WHERE
    n.nspname NOT IN ('pg_catalog', 'information_schema')
ORDER BY
    function_schema,
    function_name;

The overhead of creating the new processes is minimal, especially when it's just 4 of them. I doubt this is a performance hot spot of your application. Keep it simple, optimize where you have to and where profiling results point to.

You've probably miss-typed something above that bit of code or created your own class called IPAddress. If you're using the .net one, that function should be available.

Have you tried using System.Net.IPAddress just in case?

System.Net.IPAddress ipaddress = System.Net.IPAddress.Parse("127.0.0.1");  //127.0.0.1 as an example

The docs on Microsoft's site have a complete example which works fine on my machine.

Place your script inside the body tag

<body>
  // Rest of html
  <script>
  function hideButton() {
    $(".loading").hide();
  }
function showButton() {
  $(".loading").show();
}
</script> 
< /body>

If you check this JSFIDDLE and click on javascript, you will see the load Type body is selected

You could use a nested Any() for this check which is available on any Enumerable:

bool hasMatch = myStrings.Any(x => parameters.Any(y => y.source == x));

Faster performing on larger collections would be to project parameters to source and then use Intersect which internally uses a HashSet<T> so instead of O(n^2) for the first approach (the equivalent of two nested loops) you can do the check in O(n) :

bool hasMatch = parameters.Select(x => x.source)
                          .Intersect(myStrings)
                          .Any(); 

Also as a side comment you should capitalize your class names and property names to conform with the C# style guidelines.

Divide a division in two columns is very easy, just specify the width of your column better if you put this (like width:50%) and set the float:left for left column and float:right for right column.

How about this?

>>> tuple_list = [("pineapple", 5), ("cherry", 7), ("kumquat", 3), ("plum", 11)]
>>> [x for x, y in enumerate(tuple_list) if y[1] == 7]
[1]
>>> [x for x, y in enumerate(tuple_list) if y[0] == 'kumquat']
[2]

As pointed out in the comments, this would get all matches. To just get the first one, you can do:

>>> [y[0] for y in tuple_list].index('kumquat')
2

There is a good discussion in the comments as to the speed difference between all the solutions posted. I may be a little biased but I would personally stick to a one-liner as the speed we're talking about is pretty insignificant versus creating functions and importing modules for this problem, but if you are planning on doing this to a very large amount of elements you might want to look at the other answers provided, as they are faster than what I provided.

Android Studio can now show this. Go to Build > Analyze APK... and select your apk. Then you can see the content of the AndroidManifset file.

<input type="text" input-disabled="editableInput" />
<button ng-click="editableInput = !editableInput">enable/disable</button>

app.controller("myController", function(){
  $scope.editableInput = false;
});

app.directive("inputDisabled", function(){
  return function(scope, element, attrs){
    scope.$watch(attrs.inputDisabled, function(val){
      if(val)
        element.removeAttr("disabled");
      else
        element.attr("disabled", "disabled");
    });
  }
});

With ES6:

function test(a, b = 3) {
   console.log(a, ' ', b);
}

test(1);      // Output: 1 3
test(1, 2);   // Output: 1 2

In simple cases, the compiler converts calls to printf() to calls to puts().

For example, the following code will be compiled to the assembly code I show next.

#include <stdio.h>
main() {
    printf("Hello world!");
    return 0;
}

push rbp
mov rbp,rsp
mov edi,str.Helloworld!
call dword imp.puts
mov eax,0x0
pop rbp
ret

In this example, I used GCC version 4.7.2 and compiled the source with gcc -o hello hello.c.

Bash 4+ tested - This is the correct way to search for size 0:

find /path/to/dir -size 0 -type f -name "*.xml"

Search for multiple file extensions of size 0:

find /path/to/dir -size 0 -type f \( -iname \*.css -o -iname \*.js \)

Note: If you removed the \( ... \) the results would be all of the files that meet this requirement hence ignoring the size 0.

This should work as well.

#include <ctype.h>
#include <string.h>

template<typename T = unsigned int>
T Hex2Int(const char* const Hexstr, bool* Overflow)
{
    if (!Hexstr)
        return false;
    if (Overflow)
        *Overflow = false;

    auto between = [](char val, char c1, char c2) { return val >= c1 && val <= c2; };
    size_t len = strlen(Hexstr);
    T result = 0;

    for (size_t i = 0, offset = sizeof(T) << 3; i < len && (int)offset > 0; i++)
    {
        if (between(Hexstr[i], '0', '9'))
            result = result << 4 ^ Hexstr[i] - '0';
        else if (between(tolower(Hexstr[i]), 'a', 'f'))
            result = result << 4 ^ tolower(Hexstr[i]) - ('a' - 10); // Remove the decimal part;
        offset -= 4;
    }
    if (((len + ((len % 2) != 0)) << 2) > (sizeof(T) << 3) && Overflow)
        *Overflow = true;
    return result;
}

The 'Overflow' parameter is optional, so you can leave it NULL.

Example:

auto result = Hex2Int("C0ffee", NULL);
auto result2 = Hex2Int<long>("DeadC0ffe", NULL);

Definitely not both. Other than that I'd have to say it's a personal preference. I'd use css if I had many images the same size to reduce code.

.my_images img {width: 20px; height:20px}

In the long term CSS may win out due to HTML attribute deprecation and more likely due to the growth of vector image formats like SVG where it can actually make sense to scale images using non-pixel based units like % or em.

Only two simple steps.

1. import { Dimensions } from 'react-native' at top of your file.
2. const { height } = Dimensions.get('window');

now the window screen height is stored in the height variable.

You can use this snippet :-D

using System;
using System.Reflection;

public static class EnumUtils
{
    public static T GetDefaultValue<T>()
        where T : struct, Enum
    {
        return (T)GetDefaultValue(typeof(T));
    }

    public static object GetDefaultValue(Type enumType)
    {
        var attribute = enumType.GetCustomAttribute<DefaultValueAttribute>(inherit: false);
        if (attribute != null)
            return attribute.Value;

        var innerType = enumType.GetEnumUnderlyingType();
        var zero = Activator.CreateInstance(innerType);
        if (enumType.IsEnumDefined(zero))
            return zero;

        var values = enumType.GetEnumValues();
        return values.GetValue(0);
    }
}

Example:

using System;

public enum Enum1
{
    Foo,
    Bar,
    Baz,
    Quux
}
public enum Enum2
{
    Foo  = 1,
    Bar  = 2,
    Baz  = 3,
    Quux = 0
}
public enum Enum3
{
    Foo  = 1,
    Bar  = 2,
    Baz  = 3,
    Quux = 4
}
[DefaultValue(Enum4.Bar)]
public enum Enum4
{
    Foo  = 1,
    Bar  = 2,
    Baz  = 3,
    Quux = 4
}

public static class Program 
{
    public static void Main() 
    {
        var defaultValue1 = EnumUtils.GetDefaultValue<Enum1>();
        Console.WriteLine(defaultValue1); // Foo

        var defaultValue2 = EnumUtils.GetDefaultValue<Enum2>();
        Console.WriteLine(defaultValue2); // Quux

        var defaultValue3 = EnumUtils.GetDefaultValue<Enum3>();
        Console.WriteLine(defaultValue3); // Foo

        var defaultValue4 = EnumUtils.GetDefaultValue<Enum4>();
        Console.WriteLine(defaultValue4); // Bar
    }
}

A simple DIY way would be to make the grid yourself:

import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(111)

ax.plot([1,2,3], [2,3,4], 'ro')

for xmaj in ax.xaxis.get_majorticklocs():
  ax.axvline(x=xmaj, ls='-')
for xmin in ax.xaxis.get_minorticklocs():
  ax.axvline(x=xmin, ls='--')

for ymaj in ax.yaxis.get_majorticklocs():
  ax.axhline(y=ymaj, ls='-')
for ymin in ax.yaxis.get_minorticklocs():
  ax.axhline(y=ymin, ls='--')
plt.show()

First of all, always use re.compile() before performing any RegEx operation in a loop because it works faster than normal operation.

so for your problem first compile the pattern and then perform action on it.

import re
DATA = "Hey, you - what are you doing here!?"
reg_tok = re.compile("[\w']+")
print reg_tok.findall(DATA)

The fix was at the accepted answer. Yet if someone wants to know why it worked and why the implementation in the SO question didn't work,

First, functions are first class objects in JavaScript. That means they are treated like any other variable. Function can be passed as an argument to other functions, can be returned by another function and can be assigned as a value to a variable. Read more here.

So we use that variable to invoke the function by adding parentheses () at the end.

One thing, If you have a function that returns a funtion and you just need to call that returned function, you can just have double paranthesis when you call the outer function ()().

I use this script in mongodb console for string to float conversions...

db.documents.find({ 'fwtweaeeba' : {$exists : true}}).forEach( function(obj) { 
        obj.fwtweaeeba = parseFloat( obj.fwtweaeeba ); 
        db.documents.save(obj); } );    

db.documents.find({ 'versions.0.content.fwtweaeeba' : {$exists : true}}).forEach( function(obj) { 
        obj.versions[0].content.fwtweaeeba = parseFloat( obj.versions[0].content.fwtweaeeba ); 
        db.documents.save(obj); } );

db.documents.find({ 'versions.1.content.fwtweaeeba' : {$exists : true}}).forEach( function(obj) { 
        obj.versions[1].content.fwtweaeeba = parseFloat( obj.versions[1].content.fwtweaeeba );  
        db.documents.save(obj); } );

db.documents.find({ 'versions.2.content.fwtweaeeba' : {$exists : true}}).forEach( function(obj) { 
        obj.versions[2].content.fwtweaeeba = parseFloat( obj.versions[2].content.fwtweaeeba );  
        db.documents.save(obj); } );

And this one in php)))

foreach($db->documents->find(array("type" => "chair")) as $document){
    $db->documents->update(
        array('_id' => $document[_id]),
        array(
            '$set' => array(
                'versions.0.content.axdducvoxb' => (float)$document['versions'][0]['content']['axdducvoxb'],
                'versions.1.content.axdducvoxb' => (float)$document['versions'][1]['content']['axdducvoxb'],
                'versions.2.content.axdducvoxb' => (float)$document['versions'][2]['content']['axdducvoxb'],
                'axdducvoxb' => (float)$document['axdducvoxb']
            )
        ),
        array('$multi' => true)
    );


}

If you are into optimization, and assuming the input is always one of the four characters, the function below might be worth a try as a replacement for the map:

char map(const char in)
{ return ((in & 2) ? '\x8a' - in : '\x95' - in); }

It works based on the fact that you are dealing with two symmetric pairs. The conditional works to tell apart the A/T pair from the G/C one ('G' and 'C' happen to have the second-least-significant bit in common). The remaining arithmetics performs the symmetric mapping. It's based on the fact that a = (a + b) - b is true for any a,b.

The normal layout for a maven multi module project is:

parent
+-- pom.xml
+-- module
    +-- pom.xml

Check that you use this layout.

Additionally:

1. the relativePath looks strange. Instead of '..'

   <relativePath>..</relativePath>
   

   try '../' instead:

   <relativePath>../</relativePath>
   

   You can also remove relativePath if you use the standard layout. This is what I always do, and on the command line I can build as well the parent (and all modules) or only a single module.

2. The module path may be wrong. In the parent you define the module as:

   <module>junitcategorizer.cutdetection</module>
   

   You must specify the name of the folder of the child module, not an artifact identifier. If junitcategorizer.cutdetection is not the name of the folder than change it accordingly.

Hope that helps..

EDIT have a look at the other post, I answered there.

That approach will be good if the date-time in question is in UTC, or represents local time in an area that has never observed daylight saving time. The DateTime difference routines do not take into account Daylight Saving Time, and consequently will regard midnight June 1 as being a multiple of 24 hours after midnight January 1. I'm unaware of anything in Windows that reports historical daylight-saving rules for the current locale, so I don't think there's any good way to correctly handle any time prior to the most recent daylight-saving rule change.

xcopy  "C:\Documents and Settings\user\Desktop\?????????" "D:\Backup" /s /e /y /i

Probably the problem is the space.Try with quotes.

As far as I can tell, both syntaxes are equivalent. The first is SQL standard, the second is MySQL's extension.

So they should be exactly equivalent performance wise.

http://dev.mysql.com/doc/refman/5.6/en/insert.html says:

INSERT inserts new rows into an existing table. The INSERT ... VALUES and INSERT ... SET forms of the statement insert rows based on explicitly specified values. The INSERT ... SELECT form inserts rows selected from another table or tables.

Swift 3+

    if #available(iOS 10.0, *) {
        UNUserNotificationCenter.current().getNotificationSettings(completionHandler: { (settings: UNNotificationSettings) in
            // settings.authorizationStatus == .authorized
        })
    } else {
        return UIApplication.shared.currentUserNotificationSettings?.types.contains(UIUserNotificationType.alert) ?? false
    }

RxSwift Observable Version for iOS10+:

import UserNotifications
extension UNUserNotificationCenter {
    static var isAuthorized: Observable<Bool> {
        return Observable.create { observer in
            DispatchQueue.main.async {
                current().getNotificationSettings(completionHandler: { (settings: UNNotificationSettings) in
                    if settings.authorizationStatus == .authorized {
                        observer.onNext(true)
                        observer.onCompleted()
                    } else {
                        current().requestAuthorization(options: [.badge, .alert, .sound]) { (granted, error) in
                            observer.onNext(granted)
                            observer.onCompleted()
                        }
                    }
                })
            }
            return Disposables.create()
        }
    }
}

You need to give the user table an alias the second time you join to it

e.g.

SELECT article . * , section.title, category.title, user.name, u2.name 
FROM article 
INNER JOIN section ON article.section_id = section.id 
INNER JOIN category ON article.category_id = category.id 
INNER JOIN user ON article.author_id = user.id 
LEFT JOIN user u2 ON article.modified_by = u2.id 
WHERE article.id = '1'

This works if you just want the count of unique values in e.g. the following range

=counta(unique(B4:B21))

Unfortunately, most of the articles on state machines are written for C++ or other languages that have direct support for polymorphism as it's nice to model the states in an FSM implementation as classes that derive from an abstract state class.

However, it's pretty easy to implement state machines in C using either switch statements to dispatch events to states (for simple FSMs, they pretty much code right up) or using tables to map events to state transitions.

There are a couple of simple, but decent articles on a basic framework for state machines in C here:

• http://www.gedan.net/2008/09/08/finite-state-machine-matrix-style-c-implementation/
• http://www.gedan.net/2009/03/18/finite-state-machine-matrix-style-c-implementation-function-pointers-addon/

Edit: Site "under maintenance", web archive links:

• http://web.archive.org/web/20160517005245/http://www.gedan.net/2008/09/08/finite-state-machine-matrix-style-c-implementation
• http://web.archive.org/web/20160808120758/http://www.gedan.net/2009/03/18/finite-state-machine-matrix-style-c-implementation-function-pointers-addon/

switch statement-based state machines often use a set of macros to 'hide' the mechanics of the switch statement (or use a set of if/then/else statements instead of a switch) and make what amounts to a "FSM language" for describing the state machine in C source. I personally prefer the table-based approach, but these certainly have merit, are widely used, and can be effective especially for simpler FSMs.

One such framework is outlined by Steve Rabin in "Game Programming Gems" Chapter 3.0 (Designing a General Robust AI Engine).

A similar set of macros is discussed here:

• https://contrarymotion.net/2008/02/12/some-code-snippets-for-a-simple-c-state-machine/

If you're also interested in C++ state machine implementations there's a lot more that can be found. I'll post pointers if you're interested.

I was getting this issue intermittently, I had followed the instructions here and very similar ones elsewhere. All was configured correctly.

This page: http://sysadminwebsite.wordpress.com/2012/05/29/9/ helped me find the problem.

Basically I had duplicate CID's for the MSDTC across both servers. HKEY_CLASSES_ROOT\CID

See: http://msdn.microsoft.com/en-us/library/aa561924.aspx section Ensure that MSDTC is assigned a unique CID value

I am working with virtual servers and our server team likes to use the same image for every server. It's a simple fix and we didn't need a restart. But the DTC service did need setting to Automatic startup and did need to be started after the re-install.

Rather than trying to address the resource as a File just ask the ClassLoader to return an InputStream for the resource instead via getResourceAsStream:

InputStream in = getClass().getResourceAsStream("/file.txt"); 
BufferedReader reader = new BufferedReader(new InputStreamReader(in));

As long as the file.txt resource is available on the classpath then this approach will work the same way regardless of whether the file.txt resource is in a classes/ directory or inside a jar.

The URI is not hierarchical occurs because the URI for a resource within a jar file is going to look something like this: file:/example.jar!/file.txt. You cannot read the entries within a jar (a zip file) like it was a plain old File.

This is explained well by the answers to:

• How do I read a resource file from a Java jar file?
• Java Jar file: use resource errors: URI is not hierarchical

static void Main(string[] args)
{
    string str = "";
    string reverse = "";
    Console.WriteLine("Enter the value to reverse");
    str = Console.ReadLine();
    int length = 0;
    length = str.Length - 1;
    while(length >= 0)
    {
        reverse = reverse + str[length];
        length--;
    }
    Console.Write("Reverse string is {0}", reverse);
    Console.ReadKey();
}

There is no need to write lots of code. Even it can be done just by one line of code. See here

Below is the one line code that returns the filename only and removes extension name:

<?php
 echo pathinfo('logo.png')['filename'];
?>

It will print

logo

Source: Remove extension and return only file name in PHP

It would seem that is.nan doesn't actually have a method for data frames, unlike is.na. So, let's fix that!

is.nan.data.frame <- function(x)
do.call(cbind, lapply(x, is.nan))

data123[is.nan(data123)] <- 0

This question comes up for a number of searches related to hex color so I will add a summary here.

Color from int

Hex colors take the form RRGGBB or AARRGGBB (alpha, red, green, blue). In my experience, when using an int directly, you need to use the full AARRGGBB form. If you only have the RRGGBB form then just prefix it with FF to make the alpha (transparency) fully opaque. Here is how you would set it in code. Using 0x at the beginning means it is hexadecimal and not base 10.

int myColor = 0xFF3F51B5;
myView.setBackgroundColor(myColor);

Color from String

As others have noted, you can use Color.parseColor like so

int myColor = Color.parseColor("#3F51B5");
myView.setBackgroundColor(myColor);

Note that the String must start with a #. Both RRGGBB and AARRGGBB formats are supported.

Color from XML

You should actually be getting your colors from XML whenever possible. This is the recommended option because it makes it much easier to make color changes to your app. If you set a lot of hex colors throughout your code then it is a big pain to try to change them later.

Android material design has color palates with the hex values already configured.

• Material Design color styling
• Material Design color palette generator

These theme colors are used throughout your app and look like this:

colors.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <color name="primary">#3F51B5</color>
  <color name="primary_dark">#303F9F</color>
  <color name="primary_light">#C5CAE9</color>
  <color name="accent">#FF4081</color>
  <color name="primary_text">#212121</color>
  <color name="secondary_text">#757575</color>
  <color name="icons">#FFFFFF</color>
  <color name="divider">#BDBDBD</color>
</resources>

If you need additional colors, a good practice to follow is to define your color in two steps in xml. First name the the hex value color and then name a component of your app that should get a certain color. This makes it easy to adjust the colors later. Again, this is in colors.xml.

<color name="orange">#fff3632b</color>
<color name="my_view_background_color">@color/orange</color>

Then when you want to set the color in code, do the following:

int myColor = ContextCompat.getColor(context, R.color.my_view_background_color);    
myView.setBackgroundColor(myColor);

Android Predefined colors

The Color class comes with a number of predefined color constants. You can use it like this.

int myColor = Color.BLUE;
myView.setBackgroundColor(myColor);

Other colors are

• Color.BLACK
• Color.BLUE
• Color.CYAN
• Color.DKGRAY
• Color.GRAY
• Color.GREEN
• Color.LTGRAY
• Color.MAGENTA
• Color.RED
• Color.TRANSPARENT
• Color.WHITE
• Color.YELLOW

Notes

• A quick way to find hex colors is to open the color chooser dialog in Gimp (or some other photo editing software).
• Standard opacity levels in Material Design

If you import the module (.py) file you are creating now from another python script it will not execute the code within

if __name__ == '__main__':
    ...

If you run the script directly from the console, it will be executed.

Python does not use or require a main() function. Any code that is not protected by that guard will be executed upon execution or importing of the module.

This is expanded upon a little more at python.berkely.edu

In case of enum both are correct and right!!

I just wanted to add and give some more context on why we have these levels of test, what they really mean with examples

Mike Cohn in his book “Succeeding with Agile” came up with the “Testing Pyramid” as a way to approach automated tests in projects. There are various interpretations of this model. The model explains what kind of automated tests need to be created, how fast they can give feedback on the application under test and who writes these tests. There are basically 3 levels of automated testing needed for any project and they are as follows.

Unit Tests- These test the smallest component of your software application. This could literally be one function in a code which computes a value based on some inputs. This function is part of several other functions of the hardware/software codebase that makes up the application.

For example - Let’s take a web based calculator application. The smallest components of this application that needs to be unit tested could be a function that performs addition, another that performs subtraction and so on. All these small functions put together makes up the calculator application.

Historically developer writes these tests as they are usually written in the same programming language as the software application. Unit testing frameworks such as JUnit and NUnit (for java), MSTest (for C# and .NET) and Jasmine/Mocha (for JavaScript) are used for this purpose.

The biggest advantage of unit tests are, they run really fast underneath the UI and we can get quick feedback about the application. This should comprise more than 50% of your automated tests.

API/Integration Tests- These test various components of the software system together. The components could include testing databases, API’s (Application Programming Interface), 3rd party tools and services along with the application.

For example - In our calculator example above, the web application may use a database to store values, use API’s to do some server side validations and it may use a 3rd party tool/service to publish results to the cloud to make it available across different platforms.

Historically a developer or technical QA would write these tests using various tools such as Postman, SoapUI, JMeter and other tools like Testim.

These run much faster than UI tests as they still run underneath the hood but may consume a little more time than unit tests as it has to check the communication between various independent components of the system and ensure they have seamless integration. This should comprise more that 30% of the automated tests.

UI Tests- Finally, we have tests that validate the UI of the application. These tests are usually written to test end to end flows through the application.

For example - In the calculator application, an end to end flow could be, opening up the browser-> Entering the calculator application url -> Logging in with username/password -> Opening up the calculator application -> Performing some operations on the calculator -> verifying those results from the UI -> Logging out of the application. This could be one end to end flow that would be a good candidate for UI automation.

Historically, technical QA’s or manual testers write UI tests. They use open source frameworks like Selenium or UI testing platforms like Testim to author, execute and maintain the tests. These tests give more visual feedback as you can see how the tests are running, the difference between the expected and actual results through screenshots, logs, test reports.

The biggest limitation of UI tests is, they are relatively slow compared to Unit and API level tests. So, it should comprise only 10-20% of the overall automated tests.

The next two types of tests can vary based on your project but the idea is-

Smoke Tests

This can be a combination of the above 3 levels of testing. The idea is to run it during every code check in and ensure the critical functionalities of the system are still working as expected; after the new code changes are merged. They typically need to run with 5 - 10 mins to get faster feedback on failures

Regression Tests

They usually are run once a day at least and cover various functionalities of the system. They ensure the application is still working as expected. They are more details than the smoke tests and cover more scenarios of the application including the non-critical ones.

This is very simple If you have already set a remote origin url then you use set-url command to change that, otherwise simply use add command

1. git remote -v Check if any remote already exists
2. If Yes then use git remote set-url origin [email protected]:User/UserRepo.git to change the origin
3. If No then use git remote add origin [email protected]:User/UserRepo.git to set new origin for your repo.
4. and finally use git push -u origin master to push your code to remote and add upstream (tracking) reference to your remote branch.

NOTE: If you use -u flag, its for upstream, it enables you to use simply git pull instead of git pull origin <branch-name> in upcoming operations.

Happy Coding ;)

From "Find duplicate rows with PostgreSQL" here's smart solution:

select * from (
  SELECT id,
  ROW_NUMBER() OVER(PARTITION BY column1, column2 ORDER BY id asc) AS Row
  FROM tbl
) dups
where 
dups.Row > 1

Java always uses at least 32 bit values for calculations. This is due to the 32-bit architecture which was common 1995 when java was introduced. The register size in the CPU was 32 bit and the arithmetic logic unit accepted 2 numbers of the length of a cpu register. So the cpus were optimized for such values.

This is the reason why all datatypes which support arithmetic opperations and have less than 32-bits are converted to int (32 bit) as soon as you use them for calculations.

So to sum up it mainly was due to performance issues and is kept nowadays for compatibility.

Here is a regex that I used in Ant to obtain a proxy host IP or hostname out of ANT_OPTS. This was used to obtain the proxy IP so that I could run an Ant "isreachable" test before configuring a proxy for a forked JVM.

^.*-Dhttp\.proxyHost=(\w{1,}\.\w{1,}\.\w{1,}\.*\w{0,})\s.*$

Target build x64 Target Server Hosting IIS 64 Bit

Right Click appPool hosting running the website/web application and set the enable 32 bit application = false.

Thank it worked...

edit setting.xml

and replace proxy with this

Its working 100%

<proxy>      
  <active>true</active>
  <protocol>http</protocol>
  <username>your username</username>
  <password>password</password>    
  <host>proxy.host.net</host>
  <port>80</port>  

Add the parameter yourself.

$.get(url,{ "_": $.now() }, function(rdata){
  console.log(rdata);
});

As of jQuery 3.0, you can now do this:

$.get({
  url: url, 
  cache: false
}).then(function(rdata){
  console.log(rdata);
});

If you want connect to user@'%' from localhost use mysql -h192.168.0.1 -uuser -p.

If you have "git" or "Cygwin" on your Windows Machine, then go to the folder where your file is present and execute the command:

file *

This will give you the encoding details of all the files in that folder.

Here is what worked for me.

Install the userspace USB programming library development files

sudo apt-get install libusb-1.0-0-dev
sudo updatedb && locate libusb.h

The path should appear as (or similar)

/usr/include/libusb-1.0/libusb.h

Include the header to your C code

#include <libusb-1.0/libusb.h>

Compile your C file

gcc -o example example.c -lusb-1.0

Just thought I would help somebody with this.

Typically, you can just paste this in console.

$("body").css({"overflow":"visible"});

Or, the javascript only version:

document.body.style.overflow = "visible";

Here is the most simple way.

import tkinter as tk

root = tk.Tk()

root.geometry('200x200')
root.resizable(width=0, height=0)

root.mainloop()

I don't think there is anything to specify. It's pretty straight forward.

iOS 10 update

The ban on autoplay has been lifted as of iOS 10 - but with some restrictions (e.g. A can be autoplayed if there is no audio track).

To see a full list of these restrictions, see the official docs: https://webkit.org/blog/6784/new-video-policies-for-ios/

iOS 9 and before

As of iOS 6.1, it is no longer possible to auto-play videos on the iPad.

My assumption as to why they've disabled the auto-play feature?

Well, as many device owners have data usage/bandwidth limits on their devices, I think Apple felt that the user themselves should decide when they initiate bandwidth usage.

After a bit of research I found the following extract in the Apple documentation in regard to auto-play on iOS devices to confirm my assumption:

"Apple has made the decision to disable the automatic playing of video on iOS devices, through both script and attribute implementations.

In Safari, on iOS (for all devices, including iPad), where the user may be on a cellular network and be charged per data unit, preload and auto-play are disabled. No data is loaded until the user initiates it." - Apple documentation.

Here is a separate warning featured on the Safari HTML5 Reference page about why embedded media cannot be played in Safari on iOS:

Warning: To prevent unsolicited downloads over cellular networks at the user’s expense, embedded media cannot be played automatically in Safari on iOS—the user always initiates playback. A controller is automatically supplied on iPhone or iPod touch once playback in initiated, but for iPad you must either set the controls attribute or provide a controller using JavaScript.

What this means (in terms of code) is that Javascript's play() and load() methods are inactive until the user initiates playback, unless the play() or load() method is triggered by user action (e.g. a click event).

Basically, a user-initiated play button works, but an onLoad="play()" event does not.

For example, this would play the movie:

<input type="button" value="Play" onclick="document.myMovie.play()">

Whereas the following would do nothing on iOS:

<body onload="document.myMovie.play()">

Summary:

1. addEventListener can add multiple events, whereas with onclick this cannot be done.
2. onclick can be added as an HTML attribute, whereas an addEventListener can only be added within <script> elements.
3. addEventListener can take a third argument which can stop the event propagation.

Both can be used to handle events. However, addEventListener should be the preferred choice since it can do everything onclick does and more. Don't use inline onclick as HTML attributes as this mixes up the javascript and the HTML which is a bad practice. It makes the code less maintainable.

Another way is to use a website thumbnail/link preview service LinkPeek (even happens to show a screenshot of StackOverflow as a demo right now), URL2PNG, Browshot, Websnapr, or an alternative.

The best place to find answers to general (and somewhat easy questions) such as this is to read up on PHP docs. Specifically in your case you can read more on objects. You can store stdObject and instantiated objects within an array. In fact, there is a process known as 'hydration' which populates the member variables of an object with values from a database row, then the object is stored in an array (possibly with other objects) and returned to the calling code for access.

-- Edit --

class Car
{
    public $color;
    public $type;
}

$myCar = new Car();
$myCar->color = 'red';
$myCar->type = 'sedan';

$yourCar = new Car();
$yourCar->color = 'blue';
$yourCar->type = 'suv';

$cars = array($myCar, $yourCar);

foreach ($cars as $car) {
    echo 'This car is a ' . $car->color . ' ' . $car->type . "\n";
}

Here is some relevant code:

// Create a trust manager that does not validate certificate chains
TrustManager[] trustAllCerts = new TrustManager[]{
    new X509TrustManager() {
        public java.security.cert.X509Certificate[] getAcceptedIssuers() {
            return null;
        }
        public void checkClientTrusted(
            java.security.cert.X509Certificate[] certs, String authType) {
        }
        public void checkServerTrusted(
            java.security.cert.X509Certificate[] certs, String authType) {
        }
    }
};

// Install the all-trusting trust manager
try {
    SSLContext sc = SSLContext.getInstance("SSL");
    sc.init(null, trustAllCerts, new java.security.SecureRandom());
    HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
} catch (Exception e) {
}

// Now you can access an https URL without having the certificate in the truststore
try {
    URL url = new URL("https://hostname/index.html");
} catch (MalformedURLException e) {
}

This will completely disable SSL checking—just don't learn exception handling from such code!

To do what you want, you would have to implement a check in your TrustManager that prompts the user.

Why none of you use this?

 ''.join(filter(str.isalnum, s)) 

Too slow?

When you install postgresql no password is set for user postgres, you have to explicitly set it on Unix by using the command:

sudo passwd postgres

It will ask your sudo password and then promt you for new postgres user password. Source

Kotlin Style way to do this more simple (example):

    isVisible = false

Complete example:

    if (some_data_array.details == null){
                holder.view.some_data_array.isVisible = false}

I've hacked up the following idiom:

echo "Generating from IDL..."
idlj -fclient -td java/src echo.idl
if [ $? -ne 0 ]; then { echo "Failed, aborting." ; exit 1; } fi

echo "Compiling classes..."
javac *java
if [ $? -ne 0 ]; then { echo "Failed, aborting." ; exit 1; } fi

echo "Done."

Precede each command with an informative echo, and follow each command with that same
if [ $? -ne 0 ];... line. (Of course, you can edit that error message if you want to.)

The accepted answer works great if you just want to use a different context in your partial. However, it doesn't let you reference any of the parent context. To pass in multiple arguments, you need to write your own helper. Here's a working helper for Handlebars 2.0.0 (the other answer works for versions <2.0.0):

Handlebars.registerHelper('renderPartial', function(partialName, options) {
    if (!partialName) {
        console.error('No partial name given.');
        return '';
    }
    var partial = Handlebars.partials[partialName];
    if (!partial) {
        console.error('Couldnt find the compiled partial: ' + partialName);
        return '';
    }
    return new Handlebars.SafeString( partial(options.hash) );
});

Then in your template, you can do something like:

{{renderPartial 'myPartialName' foo=this bar=../bar}}

And in your partial, you'll be able to access those values as context like:

<div id={{bar.id}}>{{foo}}</div>

Basic Idea of using Fragments (F) is to create reusable self sustaining UI components in android applications. These Fragments are contained in activities and there are common(best) way of creating communication path ways from A -> F and F-A, It is a must to Communicate between F-F through a Activity because then only the Fragments become decoupled and self sustaining.

So passing data from A -> F is going to be the same as explained by ??s???? K. In addition to that answer, After creation of the Fragments inside an Activity, we can also pass data to the fragments calling methods in Fragments.

For example:

    ArticleFragment articleFrag = (ArticleFragment)
                    getSupportFragmentManager().findFragmentById(R.id.article_fragment);
    articleFrag.updateArticleView(position);

Casting null values is required for following construct where a method is overloaded and if null is passed to these overloaded methods then the compiler does not know how to clear up the ambiguity hence we need to typecast null in these cases:

class A {
  public void foo(Long l) {
    // do something with l
  }
  public void foo(String s) {
    // do something with s      
  }
}
new A().foo((String)null);
new A().foo((Long)null);

Otherwise you couldn't call the method you need.

If you want be sure you need to check both

SomeProperty == null || SomeProperty == Guid.Empty

Because it can be null 'Nullable' and it can be an empty GUID something like this {00000000-0000-0000-0000-000000000000}

You can use querySelectorAll:

    document.querySelectorAll('span[property=name]');

I know it's to late to answer this question. But if you are working with collection of type IList<> and you don't care about an order of the returned collection, then this method is working faster. I've used Mark Byers answer and made a little changes. So now method TakeLast is:

public static IEnumerable<T> TakeLast<T>(IList<T> source, int takeCount)
{
    if (source == null) { throw new ArgumentNullException("source"); }
    if (takeCount < 0) { throw new ArgumentOutOfRangeException("takeCount", "must not be negative"); }
    if (takeCount == 0) { yield break; }

    if (source.Count > takeCount)
    {
        for (int z = source.Count - 1; takeCount > 0; z--)
        {
            takeCount--;
            yield return source[z];
        }
    }
    else
    {
        for(int i = 0; i < source.Count; i++)
        {
            yield return source[i];
        }
    }
}

For test I have used Mark Byers method and kbrimington's andswer. This is test:

IList<int> test = new List<int>();
for(int i = 0; i<1000000; i++)
{
    test.Add(i);
}

Stopwatch stopwatch = new Stopwatch();
stopwatch.Start();

IList<int> result = TakeLast(test, 10).ToList();

stopwatch.Stop();

Stopwatch stopwatch1 = new Stopwatch();
stopwatch1.Start();

IList<int> result1 = TakeLast2(test, 10).ToList();

stopwatch1.Stop();

Stopwatch stopwatch2 = new Stopwatch();
stopwatch2.Start();

IList<int> result2 = test.Skip(Math.Max(0, test.Count - 10)).Take(10).ToList();

stopwatch2.Stop();

And here are results for taking 10 elements:

and for taking 1000001 elements results are:

One way to do it is like that:

var acceptable = {"undefined": 1, "boolean": 1, "object": 1};

if(!val && acceptable[typeof val]){
  // ...
}

I think it minimizes the number of operations given your restrictions making the check fast.

To Change Button title:

[mybtn setTitle:@"My Button" forState:UIControlStateNormal];
[mybtn setTitleColor:[UIColor blueColor] forState:UIControlStateNormal];

For Disable:

[mybtn setEnabled:NO];

For me the dialogue appears more than one if I click the dpFlightDate edit text more than one time same for the timmer dialog . how can I avoid this dialog to appear only once and if the user click's 2nd time the dialog must not appear again ie if dialog is on the screen ?

          // perform click event on edit text
            dpFlightDate.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    // calender class's instance and get current date , month and year from calender
                    final Calendar c = Calendar.getInstance();
                    int mYear = c.get(Calendar.YEAR); // current year
                    int mMonth = c.get(Calendar.MONTH); // current month
                    int mDay = c.get(Calendar.DAY_OF_MONTH); // current day
                    // date picker dialog
                    datePickerDialog = new DatePickerDialog(frmFlightDetails.this,
                            new DatePickerDialog.OnDateSetListener() {
                                @Override
                                public void onDateSet(DatePicker view, int year,
                                                      int monthOfYear, int dayOfMonth) {
                                    // set day of month , month and year value in the edit text
                                    dpFlightDate.setText(dayOfMonth + "/"
                                            + (monthOfYear + 1) + "/" + year);

                                }
                            }, mYear, mMonth, mDay);
                    datePickerDialog.show();
                }
            });
            tpFlightTime.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    // Use the current time as the default values for the picker
                    final Calendar c = Calendar.getInstance();
                    int hour = c.get(Calendar.HOUR_OF_DAY);
                    int minute = c.get(Calendar.MINUTE);
                    // Create a new instance of TimePickerDialog
                    timePickerDialog = new TimePickerDialog(frmFlightDetails.this, new TimePickerDialog.OnTimeSetListener() {
                        @Override
                        public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {
                            tpFlightTime.setText( selectedHour + ":" + selectedMinute);
                        }
                    }, hour, minute, true);//Yes 24 hour time
                    timePickerDialog.setTitle("Select Time");
                    timePickerDialog.show();
                }
            });

In my case

1. I have changed the port in postgresql.conf file
2. and restart postgresql services in

Run => service.msc => Restart

3. now retry

If you are producing the entire output yourself, you can use sprintf(), e.g.

> sprintf("%.10f",0.25)
[1] "0.2500000000"

specifies that you want to format a floating point number with ten decimal points (in %.10f the f is for float and the .10 specifies ten decimal points).

I don't know of any way of forcing R's higher level functions to print an exact number of digits.

Displaying 100 digits does not make sense if you are printing R's usual numbers, since the best accuracy you can get using 64-bit doubles is around 16 decimal digits (look at .Machine$double.eps on your system). The remaining digits will just be junk.

Best practise is to create an object (always use a . in ng-model)

In your controller:

var myObj: {
     ngModelValue: null
};

and in your template:

<select 
    ng-model="myObj.ngModelValue" 
    ng-options="o.id as o.name for o in options">
</select>

Now you can just watch

myObj.ngModelValue

or you can use the ng-change directive like so:

<select 
    ng-model="myObj.ngModelValue" 
    ng-options="o.id as o.name for o in options"
    ng-change="myChangeCallback()">

The egghead.io video "The Dot" has a really good overview, as does this very popular stack overflow question: What are the nuances of scope prototypal / prototypical inheritance in AngularJS?

I know this is very old question but I had the same requirement and just discovered that after c#6 you can use static in using for classes to import.

I hope this helps someone....

using static yourNameSpace.YourClass;

I solved this exception by changing the target sdk version from 19 onwards kitkat version AndroidManifest.xml.

<uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="19" />

the best code for UX and UI is

white-space: nowrap;
text-overflow: ellipsis;
overflow: hidden;
display: inherit;

SDK developers prefer to define their own types using typedef. This allows changing underlying types only in one place, without changing all client code. It is important to follow this convention. DWORD is unlikely to be changed, but types like DWORD_PTR are different on different platforms, like Win32 and x64. So, if some function has DWORD parameter, use DWORD and not unsigned int, and your code will be compiled in all future windows headers versions.

to update your branch from the master:

  git checkout master
  git pull
  git checkout your_branch
  git merge master

In my case, I also had to set workbench.editor.showTabs property to true (in addition to workbench.editor.enablePreview)

I'm not sure how it got changed to false. Maybe, I've accidentally set it to false using some shortcut.

Type.GetType("namespace.qualified.TypeName") only works when the type is found in either mscorlib.dll or the currently executing assembly.

If neither of those things are true, you'll need an assembly-qualified name:

Type.GetType("namespace.qualified.TypeName, Assembly.Name")

Yes. Please see the man page of bash ( the first thing you go to ) under Special Parameters

Special Parameters

The shell treats several parameters specially. These parameters may only be referenced; assignment to them is not allowed.

* Expands to the positional parameters, starting from one. When the expansion occurs within double quotes, it expands to a single word with the value of each parameter separated by the first character of the IFS special variable. That is, "$*" is equivalent to "$1c$2c...", where c is the first character of the value of the IFS variable. If IFS is unset, the parameters are separated by spaces. If IFS is null, the parameters are joined without intervening separators.

@ Expands to the positional parameters, starting from one. When the expansion occurs within double quotes, each parameter expands to a separate word. That is, "$@" is equivalent to "$1" "$2" ... If the double-quoted expansion occurs within a word, the expansion of the first parameter is joined with the beginning part of the original word, and the expansion of the last parameter is joined with the last part of the original word. When there are no positional parameters, "$@" and $@ expand to nothing (i.e., they are removed).

HTML

<input type="text" name="fieldName" id="fieldSelectorId">

This field only takes at max 10 digits number and do n't accept zero as the first digit.

JQuery

jQuery(document).ready(function () {
      jQuery("#fieldSelectorId").keypress(function (e) {
         var length = jQuery(this).val().length;
       if(length > 9) {
            return false;
       } else if(e.which != 8 && e.which != 0 && (e.which < 48 || e.which > 57)) {
            return false;
       } else if((length == 0) && (e.which == 48)) {
            return false;
       }
      });
    });

You can add a div to the td, then style that. It should work as you expected.

<td><div>AAAAAAAAAAAAAAAAAAA</div></td>

Then the css.

td div { width: 50px; overflow: hidden; }

You need to have a byte[] in your DB.

My byte[] is in my Person object:

public class Person
{
    public byte[] Image { get; set; }
}

You need to convert your byte[] in a String. So, I have in my controller :

String img = Convert.ToBase64String(person.Image);

Next, in my .cshtml file, my Model is a ViewModel. This is what I have in :

 public String Image { get; set; }

I use it like this in my .cshtml file:

<img src="@String.Format("data:image/jpg;base64,{0}", Model.Image)" />

"data:image/image file extension;base64,{0}, your image String"

I wish it will help someone !

i am not sure but, I think you can use @ResponseEntity and @ResponseBody and send 2 different one is Success and second is error message like :

@RequestMapping(value ="/book2", produces =MediaType.APPLICATION_JSON_VALUE )
@ResponseBody
Book bookInfo2() {
    Book book = new Book();
    book.setBookName("Ramcharitmanas");
    book.setWriter("TulasiDas");
    return book;
}

@RequestMapping(value ="/book3", produces =MediaType.APPLICATION_JSON_VALUE )
public ResponseEntity<Book> bookInfo3() {
    Book book = new Book();
    book.setBookName("Ramayan");
    book.setWriter("Valmiki");
    return ResponseEntity.accepted().body(book);
}

As explained in the other answers, yes you can use abstract classes in Python using the abc module. Below I give an actual example using abstract @classmethod, @property and @abstractmethod (using Python 3.6+). For me it is usually easier to start off with examples I can easily copy&paste; I hope this answer is also useful for others.

Let's first create a base class called Base:

from abc import ABC, abstractmethod

class Base(ABC):

    @classmethod
    @abstractmethod
    def from_dict(cls, d):
        pass
    
    @property
    @abstractmethod
    def prop1(self):
        pass

    @property
    @abstractmethod
    def prop2(self):
        pass

    @prop2.setter
    @abstractmethod
    def prop2(self, val):
        pass

    @abstractmethod
    def do_stuff(self):
        pass

Our Base class will always have a from_dict classmethod, a property prop1 (which is read-only) and a property prop2 (which can also be set) as well as a function called do_stuff. Whatever class is now built based on Base will have to implement all of these four methods/properties. Please note that for a method to be abstract, two decorators are required - classmethod and abstract property.

Now we could create a class A like this:

class A(Base):
    def __init__(self, name, val1, val2):
        self.name = name
        self.__val1 = val1
        self._val2 = val2

    @classmethod
    def from_dict(cls, d):
        name = d['name']
        val1 = d['val1']
        val2 = d['val2']

        return cls(name, val1, val2)

    @property
    def prop1(self):
        return self.__val1

    @property
    def prop2(self):
        return self._val2

    @prop2.setter
    def prop2(self, value):
        self._val2 = value

    def do_stuff(self):
        print('juhu!')

    def i_am_not_abstract(self):
        print('I can be customized')

All required methods/properties are implemented and we can - of course - also add additional functions that are not part of Base (here: i_am_not_abstract).

Now we can do:

a1 = A('dummy', 10, 'stuff')
a2 = A.from_dict({'name': 'from_d', 'val1': 20, 'val2': 'stuff'})

a1.prop1
# prints 10

a1.prop2
# prints 'stuff'

As desired, we cannot set prop1:

a.prop1 = 100

will return

AttributeError: can't set attribute

Also our from_dict method works fine:

a2.prop1
# prints 20

If we now defined a second class B like this:

class B(Base):
    def __init__(self, name):
        self.name = name

    @property
    def prop1(self):
        return self.name

and tried to instantiate an object like this:

b = B('iwillfail')

we will get an error

TypeError: Can't instantiate abstract class B with abstract methods do_stuff, from_dict, prop2

listing all the things defined in Base which we did not implement in B.

Respectfully to all those saying you can't insert a parameter in the middle of an alias I just tested it and found that it did work.

alias mycommand = "python3 "$1" script.py --folderoutput RESULTS/"

when I then ran mycommand foobar it worked exactly as if I had typed the command out longhand.

Let's think a little different, You can use static parameters:

class global {
    static $foo = "bar";
}

And you can use and modify it every where you like, like:

function func() {
    echo global::$foo;
}

SELECT * FROM NOTES ORDER BY UPPER(title)              

this really worked form for I am making a table using thymeleaf and inside the table there is two buttons in one form...thanks man even this thread is old it still helps me alot!

Use the Index property in your DGV's SelectedRows collection:

int index = yourDGV.SelectedRows[0].Index;

This worked for me. In case someone is looking for a VB.NET version.

@imports System

Is there an easy way to view all methods which contain this comment? Some sort of menu option?

Yes, choose one of the following:

1. Go to Window ? Show View ? Tasks (Not TaskList). The new view will show up where the "Console" and "Problems" tabs are by default.

2. As mentioned elsewhere, you can see them next to the scroll bar as little blue rectangles if you have the source file in question open.

3. If you just want the // TODO Auto-generated method stub messages (rather than all // TODO messages) you should use the search function (Ctrl-F for ones in this file Search ? Java Search ? Search string for the ability to specify this workspace, that file, this project, etc.)

You must use log4j.configuration property like this:

java -Dlog4j.configuration=file:/path/to/log4j.properties myApp

If the file is under the class-path (inside ./src/main/resources/ folder), you can omit the file:// protocol:

java -Dlog4j.configuration=path/to/log4j.properties myApp

Just in case anyone's searching for the reverse of this problem (as I sure did) here's what works for me:

def get_bytes(size, suffix):
    size = int(float(size))
    suffix = suffix.lower()

    if suffix == 'kb' or suffix == 'kib':
        return size << 10
    elif suffix == 'mb' or suffix == 'mib':
        return size << 20
    elif suffix == 'gb' or suffix == 'gib':
        return size << 30

    return False

What about this?

std::sort(numbers.begin(), numbers.end());
std::reverse(numbers.begin(), numbers.end());

The best thing is to actually use the kernel makefile to install the module:

Here is are snippets to add to your Makefile

around the top add:

PWD=$(shell pwd)
VER=$(shell uname -r)
KERNEL_BUILD=/lib/modules/$(VER)/build
# Later if you want to package the module binary you can provide an INSTALL_ROOT
# INSTALL_ROOT=/tmp/install-root

around the end add:

install:
        $(MAKE) -C $(KERNEL_BUILD) M=$(PWD) \
           INSTALL_MOD_PATH=$(INSTALL_ROOT) modules_install

and then you can issue

    sudo make install

this will put it either in /lib/modules/$(uname -r)/extra/

or /lib/modules/$(uname -r)/misc/

and run depmod appropriately

I read many threads but it is not the shortest way.

Please use command:

>copy /b NUL empty_file.txt

I get this error when I change the the storyboard file name "Main.storyboard" TO: "XXX.storyboard"

The solution for me was:

• Product->Clean
• CHANGE: Supporting Files -> info.plist -> Main storyboard file base name -> Main TO: XXX

Good Luck

<form method='post' id='userform' action='thisform.php'> <tr>
    <td>Trouble Type</td>
    <td>
    <input type='checkbox' name='checkboxvar[]' value='Option One'>1<br>
    <input type='checkbox' name='checkboxvar[]' value='Option Two'>2<br>
    <input type='checkbox' name='checkboxvar[]' value='Option Three'>3
    </td> </tr> </table> <input type='submit' class='buttons'> </form>

<?php 
if (isset($_POST['checkboxvar'])) 
{
    print_r($_POST['checkboxvar']); 
}
?>

You pass the form name as an array and then you can access all checked boxes using the var itself which would then be an array.

To echo checked options into your email you would then do this:

echo implode(',', $_POST['checkboxvar']); // change the comma to whatever separator you want

Please keep in mind you should always sanitize your input as needed.

For the record, official docs on this exist: http://php.net/manual/en/faq.html.php#faq.html.arrays

To discover any constraints used, use the code below:

-- Set the long data type for display purposes to 500000.

SET LONG 500000

-- Define a session scope variable.

VARIABLE output CLOB

-- Query the table definition through the <code>DBMS_METADATA</code> package.

SELECT dbms_metadata.get_ddl('TABLE','[Table Described]') INTO :output FROM dual;

This essentially shows a create statement for how the referenced table is made. By knowing how the table is created, you can see all of the table constraints.

Answer taken from Michael McLaughlin's blog: http://michaelmclaughlin.info/db1/lesson-5-querying-data/lab-5-querying-data/ From his Database Design I class.

Option 1 - run useEffect when value changes

const Component = (props) => {

  useEffect(() => {
    console.log("val1 has changed");
  }, [val1]);

  return <div>...</div>;
};

Demo

Option 2 - useHasChanged hook

Comparing a current value to a previous value is a common pattern, and justifies a custom hook of it's own that hides implementation details.

const Component = (props) => {
  const hasVal1Changed = useHasChanged(val1)

  useEffect(() => {
    if (hasVal1Changed ) {
      console.log("val1 has changed");
    }
  });

  return <div>...</div>;
};

const useHasChanged= (val: any) => {
    const prevVal = usePrevious(val)
    return prevVal !== val
}

const usePrevious = (value) => {
    const ref = useRef();
    useEffect(() => {
      ref.current = value;
    });
    return ref.current;
}

Demo

Here's another approach that adds a method to the Date object

usage: var d = (new Date()).parseISO8601("1971-12-15");

    /**
     * Parses the ISO 8601 formated date into a date object, ISO 8601 is YYYY-MM-DD
     * 
     * @param {String} date the date as a string eg 1971-12-15
     * @returns {Date} Date object representing the date of the supplied string
     */
    Date.prototype.parseISO8601 = function(date){
        var matches = date.match(/^\s*(\d{4})-(\d{2})-(\d{2})\s*$/);

        if(matches){
            this.setFullYear(parseInt(matches[1]));    
            this.setMonth(parseInt(matches[2]) - 1);    
            this.setDate(parseInt(matches[3]));    
        }

        return this;
    };

If you are using jQuery 1.7:

alert($(this).prop("class"));

or:

alert($(event.target).prop("class"));

It is not (with current browsers) possible to make an input field read-only through CSS alone.

Though, as you have already mentioned, you can apply the attribute readonly='readonly'.

If your main criteria is to not alter the markup in the source, there are ways to get this in, unobtrusively, with javascript.

With jQuery, this is easy:

 $('input').attr('readonly', true);

Or even with plain Javascript:

document.getElementById('someId').setAttribute('readonly', 'readonly');

MSDN says

ALTER TABLE mytable ALTER COLUMN mycolumn newtype

Beware of the limitations of the ALTER COLUMN clause listed in the article

Check the Gradle home path after the update to version 1.5. It should be ../gradle-2.8.

There's a handy ntile function in package dplyr. It's flexible in the sense that you can very easily define the number of *tiles or "bins" you want to create.

Load the package (install first if you haven't) and add the quartile column:

library(dplyr)
temp$quartile <- ntile(temp$value, 4)  

Or, if you want to use dplyr syntax:

temp <- temp %>% mutate(quartile = ntile(value, 4))

Result in both cases is:

temp
#   name       value quartile
#1     a -0.56047565        1
#2     b -0.23017749        2
#3     c  1.55870831        4
#4     d  0.07050839        2
#5     e  0.12928774        3
#6     f  1.71506499        4
#7     g  0.46091621        3
#8     h -1.26506123        1
#9     i -0.68685285        1
#10    j -0.44566197        2
#11    k  1.22408180        4
#12    l  0.35981383        3

data:

Note that you don't need to create the "quartile" column in advance and use set.seed to make the randomization reproducible:

set.seed(123)
temp <- data.frame(name=letters[1:12], value=rnorm(12))

I struggled with the same problem where I was trying to execute an update query like the same as you did-

@Modifying
@Transactional
@Query(value = "UPDATE SAMPLE_TABLE st SET st.status=:flag WHERE se.referenceNo in :ids")
public int updateStatus(@Param("flag")String flag, @Param("ids")List<String> references);

This will work if you have put @EnableTransactionManagement annotation on the main class. Spring 3.1 introduces the @EnableTransactionManagement annotation to be used in on @Configuration classes and enable transactional support.

I'd do it like this:

sudo chown -R $USER:www-data laravel-project/ 

find laravel-project/ -type f -exec chmod 664 {} \;

find laravel-project/ -type d -exec chmod 775 {} \;

then finally, you need to give webserver permission to modify the storage and bootstrap/cache directories:

sudo chgrp -R www-data storage bootstrap/cache
sudo chmod -R ug+rwx storage bootstrap/cache

Now of the other answers solved it for me. Turns out that renaming a column and an index in the same query caused the error.

Not working:

-- rename column and rename index
ALTER TABLE `client_types`
    CHANGE `template_path` `path` VARCHAR( 255 ) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL,
    DROP INDEX client_types_template_path_unique,
    ADD UNIQUE INDEX `client_types_path_unique` (`path` ASC);

Works (2 statements):

-- rename column
ALTER TABLE `client_types`
    CHANGE `template_path` `path` VARCHAR( 255 ) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL;
-- rename index
ALTER TABLE `client_types`
    DROP INDEX client_types_template_path_unique,
    ADD UNIQUE INDEX `client_types_path_unique` (`path` ASC);

This was on MariaDB 10.0.20. There were no errors with the same query on MySQL 5.5.48.

You should mention whether you want it to smoothly scroll or simply jump to an element. Jumping is easy & can be done just with HTML or Javascript. The simplest is to use anchor's. The limitation is that every element you want to scroll to has to have an id. A side effect is that #theID will be appended to the URL

<a href="#scroll">Go to Title</a>
<div>
  <h1 id="scroll">Title</h1>
</div>

You can add CSS effects to the target when the link is clicked with the CSS :target selector.

With some basic JS you can do more, namely the method scrollIntoView(). Your elements don't need an id, though it is still easier, e.g.

function onLinkClick() {
  document.getElementsByTagName('h2')[3].scrollIntoView();
  // will scroll to 4th h3 element
}

Finally, if you need smooth scrolling, you should have a look at JS Smooth Scroll or this snippet for jQuery. (NB: there are probably many more).

Check that you (git process actually) have access to file .git/info/refs and this file isn't locked by another process.

SetRetainInstance(true) allows the fragment sort of survive. Its members will be retained during configuration change like rotation. But it still may be killed when the activity is killed in the background. If the containing activity in the background is killed by the system, it's instanceState should be saved by the system you handled onSaveInstanceState properly. In another word the onSaveInstanceState will always be called. Though onCreateView won't be called if SetRetainInstance is true and fragment/activity is not killed yet, it still will be called if it's killed and being tried to be brought back.

Here are some analysis of the android activity/fragment hope it helps. http://ideaventure.blogspot.com.au/2014/01/android-activityfragment-life-cycle.html

new[,2] is a factor, not a numeric vector. Transform it first

new$MY_NEW_COLUMN <-as.numeric(as.character(new[,2])) * 5

Use this:

List<Class1> myList;
ObservableCollection<Class1> myOC = new ObservableCollection<Class1>(myList);

I realize this is an old question, but I use a much simpler way. Typically I just grab the list that I need, either by query or copying an existing list or whatever, then remove the duplicates. We will assume for this answer that your list is already in column C, row 4, as per the original question. This method works for whatever size list you have and you can select header yes or no.

Dim rng as range
Range("C4").Select
Set rng = Range(Selection, Selection.End(xlDown))
rng.RemoveDuplicates Columns:=1, Header:=xlYes

It appears you have illegal characters in your source. I cannot figure out what character \240 should be but apparently it is around the start of line 10

In the code you posted, the issue does not exist: Live On Coliru

I tried some of these answers, but they didnt work for me (sorry guys); after some more net searching I found this.

With a little modification to his code I now have this function that will return the point of intersection or if no intersection is found it will return -1,-1.

    Public Function intercetion(ByVal ax As Integer, ByVal ay As Integer, ByVal bx As Integer, ByVal by As Integer, ByVal cx As Integer, ByVal cy As Integer, ByVal dx As Integer, ByVal dy As Integer) As Point
    '//  Determines the intersection point of the line segment defined by points A and B
    '//  with the line segment defined by points C and D.
    '//
    '//  Returns YES if the intersection point was found, and stores that point in X,Y.
    '//  Returns NO if there is no determinable intersection point, in which case X,Y will
    '//  be unmodified.

    Dim distAB, theCos, theSin, newX, ABpos As Double

    '//  Fail if either line segment is zero-length.

I solved it using the LOCAL option in the command:

LOAD DATA LOCAL INFILE "text.txt" INTO TABLE mytable;

You can find more info here.

If LOCAL is specified, the file is read by the client program on the client host and sent to the server. The file can be given as a full path name to specify its exact location. If given as a relative path name, the name is interpreted relative to the directory in which the client program was started.

my problem was not including the ../ before the image name

background-image: url("../image.png");

Thanks Jim Lewis for his great answer and I would like to illustrate this solution by my function in Swift:

func getRandomLocation(forLocation location: CLLocation, withOffsetKM offset: Double) -> CLLocation {
        let latDistance = (Double(arc4random()) / Double(UInt32.max)) * offset * 2.0 - offset
        let longDistanceMax = sqrt(offset * offset - latDistance * latDistance)
        let longDistance = (Double(arc4random()) / Double(UInt32.max)) * longDistanceMax * 2.0 - longDistanceMax

        let lat: CLLocationDegrees = location.coordinate.latitude + latDistance / 110.574
        let lng: CLLocationDegrees = location.coordinate.longitude + longDistance / (111.320 * cos(lat / .pi / 180))
        return CLLocation(latitude: lat, longitude: lng)
    }

In this function to convert distance I use following formulas:

latDistance / 110.574
longDistance / (111.320 * cos(lat / .pi / 180))

In Python 3.4 you can use the pathlib module:

>>> from pathlib import Path
>>> p = Path('C:\Program Files\Internet Explorer\iexplore.exe')
>>> p.name
'iexplore.exe'
>>> p.suffix
'.exe'
>>> p.root
'\\'
>>> p.parts
('C:\\', 'Program Files', 'Internet Explorer', 'iexplore.exe')
>>> p.relative_to('C:\Program Files')
WindowsPath('Internet Explorer/iexplore.exe')
>>> p.exists()
True

This snippet works fine, for sending the Bearer Token using Jersey Client.

    WebTarget webTarget = client.target("endpoint");

    Invocation.Builder invocationBuilder =  webTarget.request(MediaType.APPLICATION_JSON);
    invocationBuilder.header("Authorization", "Bearer "+"Api Key");

    Response response = invocationBuilder.get();

    String responseData = response.readEntity(String.class);

    System.out.println(response.getStatus());
    System.out.println("responseData "+responseData);

I have passed through that error today and did everything described above but didn't work for me. So I decided to view the core problem and logged onto the MySQL root folder in Windows 7 and did this solution:

1. Go to folder:

   C:\AppServ\MySQL
   

2. Right click and Run as Administrator these files:

   mysql_servicefix.bat
   
   mysql_serviceinstall.bat
   
   mysql_servicestart.bat
   

Then close the entire explorer window and reopen it or clear cache then login to phpMyAdmin again.

Do you understand the concept of casting? Casting is the process of type conversion, which is in Java very common because its a statically typed language. Some examples:

Cast the String "1" to an int -> no problem

Cast the String "abc" to an int -> raises a ClassCastException

Or think of a class diagram with Animal.class, Dog.class and Cat.class

Animal a = new Dog();
Dog d = (Dog) a; // No problem, the type animal can be casted to a dog, because its a dog.
Cat c = (Dog) a; // Raises class cast exception; you can't cast a dog to a cat.

I had a similar task to do, but it contained some aspects that were not sufficiently covered by the other answers here:

• I wanted to convert all (in my case: two, or in general: more than one) branches of my repo.
• I had non-ASCII and (being a Windows user) non-UTF8-encoded characters (for the curious: German umlaute) in my commit messages and file names.

I did not try fast-export and hg-fast-export, since they require that you have Python and some Mercurial Python modules on your machine, which I didn't have.

I did try hg-init with TortoiseHG, and this answer gave me a good start. But it looked like it only converts the current branch, not all at once (*). So I read the hg-init docs and this blog post and added

[git]  
branch_bookmark_suffix=_bookmark

to my mercurial.ini, and did

hg bookmarks -r default master  
hg bookmarks -r my_branch my_branch_bookmark  
hg gexport

(Repeat the 2nd line for every branch you want to convert, and repeat it again if you should happen to do another commit before executing the 3rd line). This creates a folder git within .hg, which turns out to be a bare Git repo with all the exported branches. I could clone this repo and had a working copy as desired.

Or almost...

Running

git status

on my working copy showed all files with non-ASCII characters in their names as untracked files. So I continued researching and followed this advice:

git rm -rf --cached \*  
git add --all
git commit 

And finally the repo was ready to be pushed up to Bitbucket :-)

I also tried the Github importer as mentioned in this answer. I used Bitbucket as the source system, and Github did quite a good job, i.e. it converted all branches automatically. However, it showed '?'-characters for all non-ASCII characters in my commit messages (Web-UI and locally) and filenames (Web-UI only), and while I could fix the filenames as described above, I had no idea what to do with the commit messages, and so I'd prefer the hg-init approach. Without the encoding issue the Github importer would have been a perfect and fast solution (as long as you have a paid Github account or can tolerate that your repo is public for as long as it takes to pull it from Github to your local machine).

(*) So it looked like before I discovered that I have to bookmark all the branches I want to export. If you do and push to a bare (!) repo, like the linked answer says, you get all the branches.

Here's a (very inefficient) way to get all (i.e. even overlapping) matches:

>>> string = "test test test test"
>>> [i for i in range(len(string)) if string.startswith('test', i)]
[0, 5, 10, 15]

With LINQ, you could use the SkipWhile / TakeWhile methods, like this:

var importantLines = 
    File.ReadLines(pathToTextFile)
    .SkipWhile(line => !line.Contains("CustomerEN"))
    .TakeWhile(line => !line.Contains("CustomerCh"));

In my opinion this is great solution:

interface PersonRepository extends Repository<Person, UUID> {

    <T> Collection<T> findByLastname(String lastname, Class<T> type);
}

and using it like so

void someMethod(PersonRepository people) {

  Collection<Person> aggregates =
    people.findByLastname("Matthews", Person.class);

  Collection<NamesOnly> aggregates =
    people.findByLastname("Matthews", NamesOnly.class);
}

== Equality operator evaluates the arguments after converting them to numbers. So string zero "0" is converted to Number data type and boolean false is converted to Number 0. So

"0" == false // true

Same applies to `

false == "0" //true

=== Strict equality check evaluates the arguments with the original data type

"0" === false // false, because "0" is a string and false is boolean

Same applies to

false === "0" // false

In

if("0") console.log("ha");

The String "0" is not comparing with any arguments, and string is a true value until or unless it is compared with any arguments. It is exactly like

if(true) console.log("ha");

But

if (0) console.log("ha"); // empty console line, because 0 is false

`

Maybe a simpler solution is to set an overlay in front of your map using FrameLayout or RelativeLayout and treating them as regular buttons in your activity. You should declare your layers in back to front order, e.g., map before buttons. I modified your layout, simplified it a little bit. Try the following layout and see if it works for you:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MapActivity" >

    <fragment xmlns:map="http://schemas.android.com/apk/res-auto"
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:scrollbars="vertical"  
        class="com.google.android.gms.maps.SupportMapFragment"/>

    <RadioGroup 
        android:id="@+id/radio_group_list_selector"
        android:layout_width="match_parent"
        android:layout_height="48dp"
        android:orientation="horizontal" 
        android:background="#80000000"
        android:padding="4dp" >

        <RadioButton
            android:id="@+id/radioPopular"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:text="@string/Popular"
            android:gravity="center_horizontal|center_vertical"
            android:layout_weight="1"
            android:background="@drawable/shape_radiobutton"
            android:textColor="@color/textcolor_radiobutton" />
        <View
            android:id="@+id/VerticalLine"
            android:layout_width="1dip"
            android:layout_height="match_parent"
            android:background="#aaa" />

        <RadioButton
            android:id="@+id/radioAZ"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:gravity="center_horizontal|center_vertical"
            android:text="@string/AZ"
            android:layout_weight="1"
            android:background="@drawable/shape_radiobutton2"
            android:textColor="@color/textcolor_radiobutton" />

        <View
            android:id="@+id/VerticalLine"
            android:layout_width="1dip"
            android:layout_height="match_parent"
            android:background="#aaa" />

        <RadioButton
            android:id="@+id/radioCategory"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:gravity="center_horizontal|center_vertical"
            android:text="@string/Category"
            android:layout_weight="1"
            android:background="@drawable/shape_radiobutton2"
            android:textColor="@color/textcolor_radiobutton" />
        <View
            android:id="@+id/VerticalLine"
            android:layout_width="1dip"
            android:layout_height="match_parent"
            android:background="#aaa" />

        <RadioButton
            android:id="@+id/radioNearBy"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:gravity="center_horizontal|center_vertical"
            android:text="@string/NearBy"
            android:layout_weight="1"
            android:background="@drawable/shape_radiobutton3"
            android:textColor="@color/textcolor_radiobutton" />
    </RadioGroup>
</FrameLayout>

In order to achieve what you want, you need to use jQuery Ajax as below:

$('#myForm').submit(function(e){
    e.preventDefault();
    $.ajax({
        url: '/Car/Edit/17/',
        type: 'post',
        data:$('#myForm').serialize(),
        success:function(){
            // Whatever you want to do after the form is successfully submitted
        }
    });
});

Also try this one:

function SubForm(e){
    e.preventDefault();
    var url = $(this).closest('form').attr('action'),
    data = $(this).closest('form').serialize();
    $.ajax({
        url: url,
        type: 'post',
        data: data,
        success: function(){
           // Whatever you want to do after the form is successfully submitted
       }
   });
}

Final solution

This worked flawlessly. I call this function from Html.ActionLink(...)

function SubForm (){
    $.ajax({
        url: '/Person/Edit/@Model.Id/',
        type: 'post',
        data: $('#myForm').serialize(),
        success: function(){
            alert("worked");
        }
    });
}

1. Set a breakpoint as usual
2. Right click on the breakpoint and select Condition
3. You'll see a dialog that says "Breakpoint Condition"
4. Put a condition in the field e.g. "i==5"

The breakpoint will only get hit when i is 5.

sumr is implemented in terms of foldRight:

 final def sumr(implicit A: Monoid[A]): A = F.foldRight(self, A.zero)(A.append) 

foldRight is not always tail recursive, so you can overflow the stack if the collection is too long. See Why foldRight and reduceRight are NOT tail recursive? for some more discussion of when this is or isn't true.

Assuming that ID is an identity column:

INSERT INTO TheTable(HospitalID, Email, Description)
SELECT 32, Email, Description FROM TheTable
WHERE HospitalID <> 32

Try to avoid loops with SQL. Try to think in terms of sets instead.

Maybe this quick, dirty solution will work?

public class A {
    static int UNIQUE_ID = 0;
    int uid = ++UNIQUE_ID;

    public int hashCode() {
        return uid;
    }
}

This also gives the number of instance of a class being initialized.

I've created a variant of https://stackoverflow.com/a/17845473/189411

where you can set min and max text size in relation of min and max size of box that you want "check" size. In addition you can check size of dom element different than box where you want apply text size.

You resize text between 19px and 25px on #size-2 element, based on 500px and 960px width of #size-2 element

resizeTextInRange(500,960,19,25,'#size-2');

You resize text between 13px and 20px on #size-1 element, based on 500px and 960px width of body element

resizeTextInRange(500,960,13,20,'#size-1','body');

complete code are there https://github.com/kiuz/sandbox-html-js-css/tree/gh-pages/text-resize-in-range-of-text-and-screen/src

function inRange (x,min,max) {
    return Math.min(Math.max(x, min), max);
}

function resizeTextInRange(minW,maxW,textMinS,textMaxS, elementApply, elementCheck=0) {

    if(elementCheck==0){elementCheck=elementApply;}

    var ww = $(elementCheck).width();
    var difW = maxW-minW;
    var difT = textMaxS- textMinS;
    var rapW = (ww-minW);
    var out=(difT/100)*(rapW/(difW/100))+textMinS;
    var normalizedOut = inRange(out, textMinS, textMaxS);
    $(elementApply).css('font-size',normalizedOut+'px');

    console.log(normalizedOut);

}

$(function () {
    resizeTextInRange(500,960,19,25,'#size-2');
    resizeTextInRange(500,960,13,20,'#size-1','body');
    $(window).resize(function () {
        resizeTextInRange(500,960,19,25,'#size-2');
        resizeTextInRange(500,960,13,20,'#size-1','body');
    });
});

This is how i solve this issue.
The answer of Jonathan Amend on this post helped me a lot.
The example below is simplified.

For more details, the above source code is able to download a file using a JQuery Ajax request (GET, POST, PUT etc). It, also, helps to upload parameters as JSON and to change the content type to application/json (my default).

The html source:

<form method="POST">
    <input type="text" name="startDate"/>
    <input type="text" name="endDate"/>
    <input type="text" name="startDate"/>
    <select name="reportTimeDetail">
        <option value="1">1</option>
    </select>
    <button type="submit"> Submit</button>
</form>  

A simple form with two input text, one select and a button element.

The javascript page source:

<script type="text/javascript" src="JQuery 1.11.0 link"></script>
<script type="text/javascript">
    // File Download on form submition.
    $(document).on("ready", function(){
        $("form button").on("click", function (event) {
            event.stopPropagation(); // Do not propagate the event.

            // Create an object that will manage to download the file.
            new AjaxDownloadFile({
                url: "url that returns a file",
                data: JSON.stringify($("form").serializeObject())
            });

            return false; // Do not submit the form.
        });
    });
</script>  

A simple event on button click. It creates an AjaxDownloadFile object. The AjaxDownloadFile class source is below.

The AjaxDownloadFile class source:

var AjaxDownloadFile = function (configurationSettings) {
    // Standard settings.
    this.settings = {
        // JQuery AJAX default attributes.
        url: "",

        },
        data: {},
        // Custom events.
        onSuccessStart: function (response, status, xhr, self) {
        },
        onSuccessFinish: function (response, status, xhr, self, filename) {
        },
        onErrorOccured: function (response, status, xhr, self) {
        }
    };
    this.download = function () {
        var self = this;

            success: function (response, status, xhr) {
                // Start custom event.
                self.settings.onSuccessStart(response, status, xhr, self);

                // Check if a filename is existing on the response headers.

                    if (matches != null && matches[1])
                        filename = matches[1].replace(/[""]/g, "");
                }

                var type = xhr.getResponseHeader("Content-Type");
                var blob = new Blob([response], {type: type});

                    window.navigator.msSaveBlob(blob, filename);
                } else {
                    var URL = window.URL || window.webkitURL;
                    var downloadUrl = URL.createObjectURL(blob);

                    if (filename) {

I made a quick re-usable function in ES6 using Moment.js.

const getDaysDiff = (start_date, end_date, date_format = 'YYYY-MM-DD') => {_x000D_
  const getDateAsArray = (date) => {_x000D_
    return moment(date.split(/\D+/), date_format);_x000D_
  }_x000D_
  return getDateAsArray(end_date).diff(getDateAsArray(start_date), 'days') + 1;_x000D_
}_x000D_
_x000D_
console.log(getDaysDiff('2019-10-01', '2019-10-30'));_x000D_
console.log(getDaysDiff('2019/10/01', '2019/10/30'));_x000D_

Try or:

WHERE id = 3 or id = 4

Or the equivalent in:

WHERE id in (3,4)

It can be done like this:

import numpy as np

# create a random matrix:
A = np.random.normal(size=(5,2))

# add a column of zeros to it:
print(np.hstack((A,np.zeros((A.shape[0],1)))))

In general, if A is an m*n matrix, and you need to add a column, you have to create an n*1 matrix of zeros, then use "hstack" to add the matrix of zeros to the right of the matrix A.

Don't fret too much if your initial API is fully RESTful or not (specially when you are just in the alpha stages). Get the back-end plumbing to work first. You can always do some sort of URL transformation/re-writing to map things out, refining iteratively until you get something stable enough for widespread testing ("beta").

You can define URIs whose parameters are encoded by position and convention on the URIs themselves, prefixed by a path you know you'll always map to something. I don't know PHP, but I would assume that such a facility exists (as it exists in other languages with web frameworks):

.ie. Do a "user" type of search with param[i]=value[i] for i=1..4 on store #1 (with value1,value2,value3,... as a shorthand for URI query parameters):

1) GET /store1/search/user/value1,value2,value3,value4

or

2) GET /store1/search/user,value1,value2,value3,value4

or as follows (though I would not recommend it, more on that later)

3) GET /search/store1,user,value1,value2,value3,value4

With option 1, you map all URIs prefixed with /store1/search/user to the search handler (or whichever the PHP designation) defaulting to do searches for resources under store1 (equivalent to /search?location=store1&type=user.

By convention documented and enforced by the API, parameters values 1 through 4 are separated by commas and presented in that order.

Option 2 adds the search type (in this case user) as positional parameter #1. Either option is just a cosmetic choice.

Option 3 is also possible, but I don't think I would like it. I think the ability of search within certain resources should be presented in the URI itself preceding the search itself (as if indicating clearly in the URI that the search is specific within the resource.)

The advantage of this over passing parameters on the URI is that the search is part of the URI (thus treating a search as a resource, a resource whose contents can - and will - change over time.) The disadvantage is that parameter order is mandatory.

Once you do something like this, you can use GET, and it would be a read-only resource (since you can't POST or PUT to it - it gets updated when it's GET'ed). It would also be a resource that only comes to exist when it is invoked.

One could also add more semantics to it by caching the results for a period of time or with a DELETE causing the cache to be deleted. This, however, might run counter to what people typically use DELETE for (and because people typically control caching with caching headers.)

How you go about it would be a design decision, but this would be the way I'd go about. It is not perfect, and I'm sure there will be cases where doing this is not the best thing to do (specially for very complex search criteria).

Why don't you use cURL ?

$yourkey="your api key";
$url="https://prod.api.pvp.net/api/lol/euw/v1.1/game/by-summoner/20986461/recent?api_key=$yourkey";
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);

$auth = curl_exec($curl);
if($auth)
{
$json = json_decode($auth); 
print_r($json);
}
}

To Fix The "Missing "server" JVM at C:\Program Files\Java\jre7\bin\server\jvm­­.dll, please install or use the JRE or JDK that contains these missing components.

Follow these steps:

Go to oracle.com and install Java JRE7 (Check if Java 6 is not installed already)

After that, go to C:/Program files/java/jre7/bin

Here, create an folder called Server

Now go into the C:/Program files/java/jre7/bin/client folder

Copy all the data in this folder into the new C:/Program files/java/jre7/bin/Server folder

a is an array local to the function.Once the function returns it does not exist anymore and hence you should not return the address of a local variable.
In other words the lifetime of a is within the scope({,}) of the function and if you return a pointer to it what you have is a pointer pointing to some memory which is not valid. Such variables are also called automatic variabels because their lifetime is automatically managed you do not need to manage it explicitly.

Since you need to extend the variable to persist beyond the scope of the function you You need to allocate a array on heap and return a pointer to it.

char *a = malloc(1000); 

This way the array a resides in memory untill you call a free() on the same address.
Do not forget to do so or you end up with a memory leak.

Reset the sequence:

SELECT setval('sequence_name', 0);

Updating current records:

UPDATE foo SET id = DEFAULT;

Please make sure two things:

1- Use @Bean annotation with the method.

@Bean
public RestTemplate restTemplate(RestTemplateBuilder builder){
    return builder.build();
}

2- Scope of this method should be public not private.

Complete Example -

@Service
public class MakeHttpsCallImpl implements MakeHttpsCall {

@Autowired
private RestTemplate restTemplate;

@Override
public String makeHttpsCall() {
    return restTemplate.getForObject("https://localhost:8085/onewayssl/v1/test",String.class);
}

@Bean
public RestTemplate restTemplate(RestTemplateBuilder builder){
    return builder.build();
}
}

I just needed some random images for testing, so this is how I did it.

I have the simplest solution in the world. Just open Safari in the simulator, go to Google images (or your own web or Dropbox URL), view an image, hold down the mouse button for 2 seconds, and you'll see "Save Image" - it will save right into the Photos library. Rinse and repeat.

Here's an example using @ars accepted answer and the BeautifulSoup4, requests, and wget modules to handle the downloads.

import requests
import wget
import os

from bs4 import BeautifulSoup, SoupStrainer

url = 'https://archive.ics.uci.edu/ml/machine-learning-databases/eeg-mld/eeg_full/'
file_type = '.tar.gz'

response = requests.get(url)

for link in BeautifulSoup(response.content, 'html.parser', parse_only=SoupStrainer('a')):
    if link.has_attr('href'):
        if file_type in link['href']:
            full_path = url + link['href']
            wget.download(full_path)

great answer from @David, here is for Python 3 without the generic try-except:

def send_email(user, password, recipient, subject, body):

    gmail_user = user
    gmail_pwd = password
    FROM = user
    TO = recipient if type(recipient) is list else [recipient]
    SUBJECT = subject
    TEXT = body

    # Prepare actual message
    message = """From: %s\nTo: %s\nSubject: %s\n\n%s
    """ % (FROM, ", ".join(TO), SUBJECT, TEXT)

    server = smtplib.SMTP("smtp.gmail.com", 587)
    server.ehlo()
    server.starttls()
    server.login(gmail_user, gmail_pwd)
    server.sendmail(FROM, TO, message)
    server.close()

As @CRice said you can use the below method to get a list of dependent assembly with publicKeyToken

public static int DependencyInfo(string args) 
{
    Console.WriteLine(Assembly.LoadFile(args).FullName);
    Console.WriteLine(Assembly.LoadFile(args).GetCustomAttributes(typeof(System.Runtime.Versioning.TargetFrameworkAttribute), false).SingleOrDefault());
    try {
        var assemblies = Assembly.LoadFile(args).GetReferencedAssemblies(); 

        if (assemblies.GetLength(0) > 0)
        {
            foreach (var assembly in assemblies)
            {
                Console.WriteLine(" - " + assembly.FullName + ", ProcessorArchitecture=" + assembly.ProcessorArchitecture);             
            }
            return 0;
        }
    }
    catch(Exception e) {
        Console.WriteLine("An exception occurred: {0}", e.Message);
        return 1;
    } 
    finally{}

    return 1;
}

i generally use it as a LinqPad script you can call it as

DependencyInfo("@c:\MyAssembly.dll"); from the code

Here is a very simple answer to this(only one line).

You can do that after you added the 'n' column into your df as follows.

import pandas as pd
df = pd.DataFrame({'l':['a','b','c','d'], 'v':[1,2,1,2]})
df['n'] = 0

df
    l   v   n
0   a   1   0
1   b   2   0
2   c   1   0
3   d   2   0

# here you can add the below code and it should work.
df = df[list('nlv')]
df

    n   l   v
0   0   a   1
1   0   b   2
2   0   c   1
3   0   d   2



However, if you have words in your columns names instead of letters. It should include two brackets around your column names. 

import pandas as pd
df = pd.DataFrame({'Upper':['a','b','c','d'], 'Lower':[1,2,1,2]})
df['Net'] = 0
df['Mid'] = 2
df['Zsore'] = 2

df

    Upper   Lower   Net Mid Zsore
0   a       1       0   2   2
1   b       2       0   2   2
2   c       1       0   2   2
3   d       2       0   2   2

# here you can add below line and it should work 
df = df[list(('Mid','Upper', 'Lower', 'Net','Zsore'))]
df

   Mid  Upper   Lower   Net Zsore
0   2   a       1       0   2
1   2   b       2       0   2
2   2   c       1       0   2
3   2   d       2       0   2

On the following option:

WebElement option = select.getFirstSelectedOption();
option.getText();

If from the method getText() you get a blank, you can get the string from the value of the option using the method getAttribute:

WebElement option = select.getFirstSelectedOption();
option.getAttribute("value");

From http://en.wikipedia.org/wiki/Base64

The term Base64 refers to a specific MIME content transfer encoding. It is also used as a generic term for any similar encoding scheme that encodes binary data by treating it numerically and translating it into a base 64 representation. The particular choice of base is due to the history of character set encoding: one can choose a set of 64 characters that is both part of the subset common to most encodings, and also printable. This combination leaves the data unlikely to be modified in transit through systems, such as email, which were traditionally not 8-bit clean.

Base64 can be used in a variety of contexts:

• Evolution and Thunderbird use Base64 to obfuscate e-mail passwords[1]
• Base64 can be used to transmit and store text that might otherwise cause delimiter collision

• Base64 is often used as a quick but insecure shortcut to obscure secrets without incurring the overhead of cryptographic key management

• Spammers use Base64 to evade basic anti-spamming tools, which often do not decode Base64 and therefore cannot detect keywords in encoded messages.

• Base64 is used to encode character strings in LDIF files
• Base64 is sometimes used to embed binary data in an XML file, using a syntax similar to ...... e.g. Firefox's bookmarks.html.
• Base64 is also used when communicating with government Fiscal Signature printing devices (usually, over serial or parallel ports) to minimize the delay when transferring receipt characters for signing.
• Base64 is used to encode binary files such as images within scripts, to avoid depending on external files.
• Can be used to embed raw image data into a CSS property such as background-image.

If you encountered this error while making an ad hoc deployment, this is now fixed in the XCode 7.3.1 release (May 3th, 2016) : https://itunes.apple.com/us/app/xcode/id497799835?ls=1&mt=12

Changelog 7.3.1 :

• Git updated to version 2.7.4 to improve security
• Fixed an issue where turning off a capability in the Xcode editor could leave the entitlement enabled in the app bundle
• Fixed an issue that could prevent the export of an ad-hoc build from an archive
• Fixed a crash when importing localizations

Here is the detailed explanation of why "Random.nextInt(n) is both more efficient and less biased than Math.random() * n" from the Sun forums post that Gili linked to:

Math.random() uses Random.nextDouble() internally.

Random.nextDouble() uses Random.next() twice to generate a double that has approximately uniformly distributed bits in its mantissa, so it is uniformly distributed in the range 0 to 1-(2^-53).

Random.nextInt(n) uses Random.next() less than twice on average- it uses it once, and if the value obtained is above the highest multiple of n below MAX_INT it tries again, otherwise is returns the value modulo n (this prevents the values above the highest multiple of n below MAX_INT skewing the distribution), so returning a value which is uniformly distributed in the range 0 to n-1.

Prior to scaling by 6, the output of Math.random() is one of 2^53 possible values drawn from a uniform distribution.

Scaling by 6 doesn't alter the number of possible values, and casting to an int then forces these values into one of six 'buckets' (0, 1, 2, 3, 4, 5), each bucket corresponding to ranges encompassing either 1501199875790165 or 1501199875790166 of the possible values (as 6 is not a disvisor of 2^53). This means that for a sufficient number of dice rolls (or a die with a sufficiently large number of sides), the die will show itself to be biased towards the larger buckets.

You will be waiting a very long time rolling dice for this effect to show up.

Math.random() also requires about twice the processing and is subject to synchronization.

Found an elegant solution using decorators, which addresses the following problem: what if you are writing a module with several functions, each of them with several debugging messages, and you want to disable logging in all functions but the one you are currently focusing on?

You can do it using decorators:

import logging, sys
logger = logging.getLogger()
logging.basicConfig(stream=sys.stderr, level=logging.DEBUG)


def disable_debug_messages(func):
    def wrapper(*args, **kwargs):
        prev_state = logger.disabled
        logger.disabled = True
        result = func(*args, **kwargs)
        logger.disabled = prev_state
        return result
    return wrapper

Then, you can do:

@disable_debug_messages
def function_already_debugged():
    ...
    logger.debug("This message won't be showed because of the decorator")
    ...

def function_being_focused():
    ...
    logger.debug("This message will be showed")
    ...

Even if you call function_already_debugged from within function_being_focused, debug messages from function_already_debugged won't be showed. This ensures you will see only the debug messages from the function you are focusing on.

Hope it helps!

The public modifier should be omitted in Java interfaces (in my opinion).

Since it does not add any extra information, it just draws attention away from the important stuff.

Most style-guides will recommend that you leave it out, but of course, the most important thing is to be consistent across your codebase, and especially for each interface. The following example could easily confuse someone, who is not 100% fluent in Java:

public interface Foo{
  public void MakeFoo();
  void PerformBar();
}

Would you be happy to make "my file.xls" active if it didn't affect the screen? Turning off screen updating is the way to achieve this, it also has performance improvements (significant if you are doing looping while switching around worksheets / workbooks).

The command to do this is:

    Application.ScreenUpdating = False

Don't forget to turn it back to True when your macros is finished.

Try this in MySQL.

right(field,((CHAR_LENGTH(field))-(InStr(field,','))))

To lessen the impact on code readabilty, I'd suggest:

v = 1d* s/t;

The problem here is that in Python the % operator returns the modulus and in Java it returns the remainder. These functions give the same values for positive arguments, but the modulus always returns positive results for negative input, whereas the remainder may give negative results. There's some more information about it in this question.

You can find the positive value by doing this:

int i = (((-1 % 2) + 2) % 2)

or this:

int i = -1 % 2;
if (i<0) i += 2;

(obviously -1 or 2 can be whatever you want the numerator or denominator to be)

You can use

<%
Response.Write("Version: " + System.Environment.Version.ToString());
%>

That will get the currently running version. You can check the registry for all installed versions at:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP

Doing this with POSIX is tricky:

• POSIX Sed does not support \r or \15. Even if it did, the in place option -i is not POSIX

• POSIX Awk does support \r and \15, however the -i inplace option is not POSIX

• d2u and dos2unix are not POSIX utilities, but ex is

• POSIX ex does not support \r, \15, \n or \12

To remove carriage returns:

awk 'BEGIN{RS="^$";ORS="";getline;gsub("\r","");print>ARGV[1]}' file

To add carriage returns:

awk 'BEGIN{RS="^$";ORS="";getline;gsub("\n","\r&");print>ARGV[1]}' file

If you want to use SelectedValue then your combobox must be databound.

To set up the combobox:

ComboBox1.DataSource = GetMailItems()
ComboBox1.DisplayMember = "Name"
ComboBox1.ValueMember = "ID"

To get the data:

Function GetMailItems() As List(Of MailItem)

    Dim mailItems = New List(Of MailItem)

    Command = New MySqlCommand("SELECT * FROM `maillist` WHERE l_id = '" & id & "'", connection)
    Command.CommandTimeout = 30
    Reader = Command.ExecuteReader()

    If Reader.HasRows = True Then
        While Reader.Read()
            mailItems.Add(New MailItem(Reader("ID"), Reader("name")))
        End While
    End If

    Return mailItems

End Function

Public Class MailItem

    Public Sub New(ByVal id As Integer, ByVal name As String)
        mID = id
        mName = name
    End Sub

    Private mID As Integer
    Public Property ID() As Integer
        Get
            Return mID
        End Get
        Set(ByVal value As Integer)
            mID = value
        End Set
    End Property

    Private mName As String
    Public Property Name() As String
        Get
            Return mName
        End Get
        Set(ByVal value As String)
            mName = value
        End Set
    End Property

End Class

If you're not completely attached to using "from" and "to" as your option names, it's fairly easy to implement this using getopts:

while getopts f:t: opts; do
   case ${opts} in
      f) FROM_VAL=${OPTARG} ;;
      t) TO_VAL=${OPTARG} ;;
   esac
done

getopts is a program that processes command line arguments and conveniently parses them for you.

f:t: specifies that you're expecting 2 parameters that contain values (indicated by the colon). Something like f:t:v says that -v will only be interpreted as a flag.

opts is where the current parameter is stored. The case statement is where you will process this.

${OPTARG} contains the value following the parameter. ${FROM_VAL} for example will get the value /home/kristoffer/test.png if you ran your script like:

ocrscript.sh -f /home/kristoffer/test.png -t /home/kristoffer/test.txt

As the others are suggesting, if this is your first time writing bash scripts you should really read up on some basics. This was just a quick tutorial on how getopts works.

You have 2 options, and I am not sure if I am a fan of either of them, but that is my opinion. You may feel differently:

Option 1: Force the function to run.

A function in a cell does not run unless it references a cell that has changed. Changing a sheet name does not trigger any functions in the spreadsheet. But we can force the function to run by passing a range to it and whenever an item in that range changes, the function will trigger.

You can use the below script to create a custom function which will retrieve the name:

function mySheetName() {
  var key = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet().getName();
  return key;
}

and in the cell place the following:

=mySheetName(A1:Z)

Now if any value in a cell in that passed range changes the script will run. This takes a second to run the script and sets a message in the cell each time any value is changed so this could become annoying very quickly. As already mentioned, it also requires a change in the range to cause it to trigger, so not really helpful on a fairly static file.

Option 2: Use the OnChange Event

While the run time feels better than the above option, and this does not depend on a value changing in the spreadsheet's cells, I do not like this because it forces where the name goes. You could use a Utilities sheet to define this location in various sheets if you wish. Below is the basic idea and may get you started if you like this option.

The OnChange event is triggered when the sheet name is changed. You can make the code below more sophisticated to check for errors, check the sheet ID to only work on a given sheet, etc. The basic code, however, is:

function setSheetName(e) {
  var key = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet().getName();
  SpreadsheetApp.getActiveSpreadsheet().getActiveSheet().getRange('K1').setValue(key);
}

Once you have saved the code, in the script editor set the Current Project's On Change Trigger to this function. It will write the sheet name to cell K1 on any change event. To set the trigger, select Current project's triggers under the Edit menu.

There is a mistake in your insert statement chage it to below and try : String sql = "insert into table_name values ('" + Col1 +"','" + Col2 + "','" + Col3 + "')";

If you are using Java 6, you can use the following oneliner to read an integer from console:

int n = Integer.parseInt(System.console().readLine());

background-image: url("/your-dir/your_image.jpg");
min-height: 100%;
background-repeat: no-repeat;
background-attachment: fixed;
background-position: center;
background-size: cover;}

1) Requires .NET framework 4 updated to at least 4.0.2. If you have 4.0.2, then you should have

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319\SKUs\.NETFramework,Version=v4.0.2

If you have installed latest VS 2012 chances are that you already have 4.0.2. Just verify first.

2) Next you need to have an instance of LocalDb. By default you have an instance whose name is a single v character followed by the LocalDB release version number in the format xx.x. For example, v11.0 represents SQL Server 2012. Automatic instances are public by default. You can also have named instances which are private. Named instances provide isolation from other instances and can improve performance by reducing resource contention with other database users. You can check the status of instances using the SqlLocalDb.exe utility (run it from command line).

3) Next your connection string should look like:

"Server=(localdb)\\v11.0;Integrated Security=true;"

or

"Data Source=(localdb)\\test;Integrated Security=true;"

from your code. They both are the same. Notice the two \\ required because \v and \t means special characters. Also note that what appears after (localdb)\\ is the name of your LocalDb instance. v11.0 is the default public instance, test is something I have created manually which is private.

1. If you have a database (.mdf file) already:

   "Server=(localdb)\\Test;Integrated Security=true;AttachDbFileName= myDbFile;"
   

2. If you don't have a Sql Server database:

   "Server=(localdb)\\v11.0;Integrated Security=true;"
   

And you can create your own database programmatically:

a) to save it in the default location with default setting:

var query = "CREATE DATABASE myDbName;";

b) To save it in a specific location with your own custom settings:

// your db name
string dbName = "myDbName";

// path to your db files:
// ensure that the directory exists and you have read write permission.
string[] files = { Path.Combine(Application.StartupPath, dbName + ".mdf"), 
                   Path.Combine(Application.StartupPath, dbName + ".ldf") };

// db creation query:
// note that the data file and log file have different logical names
var query = "CREATE DATABASE " + dbName +
    " ON PRIMARY" +
    " (NAME = " + dbName + "_data," +
    " FILENAME = '" + files[0] + "'," +
    " SIZE = 3MB," +
    " MAXSIZE = 10MB," +
    " FILEGROWTH = 10%)" +

    " LOG ON" +
    " (NAME = " + dbName + "_log," +
    " FILENAME = '" + files[1] + "'," +
    " SIZE = 1MB," +
    " MAXSIZE = 5MB," +
    " FILEGROWTH = 10%)" +
    ";";

And execute!

A sample table can be loaded into the database with something like:

 @"CREATE TABLE supportContacts 
    (
        id int identity primary key, 
        type varchar(20), 
        details varchar(30)
    );
   INSERT INTO supportContacts
   (type, details)
   VALUES
   ('Email', '[email protected]'),
   ('Twitter', '@sqlfiddle');";

Note that SqlLocalDb.exe utility doesnt give you access to databases, you separately need sqlcmd utility which is sad..

EDIT: moved position of semicolon otherwise error would occur if code was copy/pasted

1) WebClient is a managed type, so you don't need a finalizer. The finalizer is needed in the case your users don't Dispose() of your NoGateway class and the native type (which is not collected by the GC) needs to be cleaned up after. In this case, if the user doesn't call Dispose(), the contained WebClient will be disposed by the GC right after the NoGateway does.

2) Indirectly yes, but you shouldn't have to worry about it. Your code is correct as stands and you cannot prevent your users from forgetting to Dispose() very easily.

You can change the value of tuple using copy by reference

>>> tuple1=[20,30,40]

>>> tuple2=tuple1

>>> tuple2
    [20, 30, 40]

>>> tuple2[1]=10

>>> print(tuple2)
    [20, 10, 40]

>>> print(tuple1)
    [20, 10, 40]

1. Using EntrySet() and for each loop

      for(Map.Entry<String, String> entry: hashMap.entrySet()) {
        System.out.println("Key Of map = "+ entry.getKey() + 
                         " , value of map = " + entry.getValue() );
    }
   

2. Using keyset() and for each loop

            for(String key : hashMap.keySet()) {
               System.out.println("Key Of map = "+ key + " , 
                         value of map = " + hashMap.get(key) );
              }
   

3. Using EntrySet() and java Iterator

         for(String key : hashMap.keySet()) {
           System.out.println("Key Of map = "+ key + " , 
                         value of map = " + hashMap.get(key) );
           }
   

4. Using keyset() and java Iterator

        Iterator<String> keysIterator = keySet.iterator();
       while (keysIterator.hasNext()) {
           String key = keysIterator.next();
           System.out.println("Key Of map = "+ key + " , value of map = " + hashMap.get(key) );
      }

Set a breakpoint on malloc_error_break() by opening the Breakpoint Navigator (View->Navigators->Show Breakpoint Navigator or ?8), clicking the plus button in the lower left corner, and selecting "Add Symbolic Breakpoint". In the popup that comes up, enter malloc_error_break in the Symbol field, then click Done.

EDIT: openfrog added a screenshot and indicated that he's already tried these steps without success after I posted my answer. With that edit, I'm not sure what to say. I haven't seen that fail to work myself, and indeed I always keep a breakpoint on malloc_error_break set.

You can try this:-

Process p = Runtime.getRuntime().exec(command);

Depending on your needs, a simple divide-and-conquer strategy can be used. It won't converge as fast as some other methods but it may be a lot easier for a novice to understand. In addition, since it's an O(log n) algorithm (halving the search space each iteration), the worst case for a 32-bit float will be 32 iterations.

Let's say you want the square root of 62.104. You pick a value halfway between 0 and that, and square it. If the square is higher than your number, you need to concentrate on numbers less than the midpoint. If it's too low, concentrate on those higher.

With real math, you could keep dividing the search space in two forever (if it doesn't have a rational square root). In reality, computers will eventually run out of precision and you'll have your approximation. The following C program illustrates the point:

#include <stdio.h>
#include <stdlib.h>

int main (int argc, char *argv[]) {
    float val, low, high, mid, oldmid, midsqr;
    int step = 0;

    // Get argument, force to non-negative.

    if (argc < 2) {
        printf ("Usage: sqrt <number>\n");
        return 1;
    }
    val = fabs (atof (argv[1]));

    // Set initial bounds and print heading.

    low = 0;
    high = mid = val;
    oldmid = -1;

    printf ("%4s  %10s  %10s  %10s  %10s  %10s    %s\n",
        "Step", "Number", "Low", "High", "Mid", "Square", "Result");

    // Keep going until accurate enough.

    while (fabs(oldmid - mid) >= 0.00001) {
        oldmid = mid;

        // Get midpoint and see if we need lower or higher.

        mid = (high + low) / 2;
        midsqr = mid * mid;
        printf ("%4d  %10.4f  %10.4f  %10.4f  %10.4f  %10.4f  ",
            ++step, val, low, high, mid, midsqr);
        if (mid * mid > val) {
            high = mid;
            printf ("- too high\n");
        } else {
            low = mid;
            printf ("- too low\n");
        }
    }

    // Desired accuracy reached, print it.

    printf ("sqrt(%.4f) = %.4f\n", val, mid);
    return 0;
}

There is a comprehensive doc for google calendar and other calendar services: https://github.com/InteractionDesignFoundation/add-event-to-calendar-docs/blob/master/services/google.md

An example of working link: https://calendar.google.com/calendar/render?action=TEMPLATE&text=Bithday&dates=20201231T193000Z/20201231T223000Z&details=With%20clowns%20and%20stuff&location=North%20Pole

Whenever I have to do something like this I just become root:

# sudo -s
# ls -hal /root/ > /root/test.out
# exit

It's probably not the best way, but it works.

By converting it to a datetime, you can get localized formats:

new DateTime(timeSpan.Ticks).ToString("HH:mm");

I can see it's an old question, if you want to put other HTML inside could use the radiobutton with GroupName propery same in all radiobuttons and in the Text property set something like an image or the html you need.

   <asp:RadioButton GroupName="group1" runat="server" ID="paypalrb" Text="<img src='https://www.paypalobjects.com/webstatic/mktg/logo/bdg_secured_by_pp_2line.png' border='0' alt='Secured by PayPal' style='width: 103px; height: 61px; padding:10px;'>" />

If I first install BLAS, LAPACK and GCC Fortran as system packages (I'm using Arch Linux), I can get SciPy installed with:

pip install scipy
