If you're only running the commands in one shot then you can just use subprocess.check_output convenience function:

def subprocess_cmd(command):
    output = subprocess.check_output(command, shell=True)
    print output

I was having a similar issue. I simply added the following to my code:

closeInfoWindow = function() {
    infoWindow.close();
};

google.maps.event.addListener(map, 'click', closeInfoWindow);

The full js code is (the code above is about 15 lines from the bottom):

jQuery(window).load(function() {
if (jQuery("#map_canvas").length > 0){
    googlemap();
}
});

function googlemap() {

jQuery('#map_canvas').css({'height': '400px'});

// Create the map 
// No need to specify zoom and center as we fit the map further down.
var map = new google.maps.Map(document.getElementById("map_canvas"), {
  mapTypeId: google.maps.MapTypeId.ROADMAP,
  streetViewControl: false
});

// Create the shared infowindow with two DIV placeholders
// One for a text string, the other for the StreetView panorama.
var content = document.createElement("div");
var title = document.createElement("div");
var boxText = document.createElement("div");

var myOptions = {
         content: boxText
        ,disableAutoPan: false
        ,maxWidth: 0
        ,pixelOffset: new google.maps.Size(-117,-200)
        ,zIndex: null
        ,boxStyle: { 
          background: "url('"+siteRoot+"images/house-icon-flat.png') no-repeat"
          ,opacity: 1
          ,width: "236px"
          ,height: "300px"
         }
        ,closeBoxMargin: "10px 0px 2px 2px"
        ,closeBoxURL: "http://kdev.langley.com/wp-content/themes/langley/images/close.gif"
        ,infoBoxClearance: new google.maps.Size(1, 1)
        ,isHidden: false
        ,pane: "floatPane"
        ,enableEventPropagation: false
};


var infoWindow = new InfoBox(myOptions);
var MarkerImage = siteRoot+'images/house-web-marker.png';

// Create the markers
for (index in markers) addMarker(markers[index]);
function addMarker(data) {
    var marker = new google.maps.Marker({
        position: new google.maps.LatLng(data.lat, data.lng),
        map: map,
        title: data.title,
        content: data.html,
        icon: MarkerImage
    });
    google.maps.event.addListener(marker, "click", function() {
        infoWindow.open(map, this);         
        title.innerHTML = marker.getTitle();
        infoWindow.setContent(marker.content);
        infoWindow.open(map, marker);
        jQuery(".innerinfo").parent().css({'overflow':'hidden', 'margin-right':'10px'});            
    });
}

// Zoom and center the map to fit the markers
// This logic could be conbined with the marker creation.
// Just keeping it separate for code clarity.
var bounds = new google.maps.LatLngBounds();
for (index in markers) {
    var data = markers[index];
    bounds.extend(new google.maps.LatLng(data.lat, data.lng));
}
map.fitBounds(bounds);
var origcent = new google.maps.LatLng(map.getCenter());
// Handle the DOM ready event to create the StreetView panorama
// as it can only be created once the DIV inside the infowindow is loaded in the DOM.

closeInfoWindow = function() {
        infoWindow.close();
    };

google.maps.event.addListener(map, 'click', closeInfoWindow);

google.maps.event.addListener(infoWindow, 'closeclick', function()
{
    centermap();
});

function centermap()
{
    map.setCenter(map.fitBounds(bounds));
}
}

jQuery(window).resize(function() {
googlemap();
});

Construct your method to accept it-

public <T> void printClassNameAndCreateList(Class<T> className){
    //example access 1
    System.out.print(className.getName());

    //example access 2
    ArrayList<T> list = new ArrayList<T>();
    //note that if you create a list this way, you will have to cast input
    list.add((T)nameOfObject);
}

Call the method-

printClassNameAndCreateList(SomeClass.class);

You can also restrict the type of class, for example, this is one of the methods from a library I made-

protected Class postExceptionActivityIn;

protected <T extends PostExceptionActivity>  void  setPostExceptionActivityIn(Class <T> postExceptionActivityIn) {
    this.postExceptionActivityIn = postExceptionActivityIn;
}

For more information, search Reflection and Generics.

I've several plugins (including Unicode Character Highlighter), but the only one which found the character that was hiding from me today was Highlighter.

You can test to see if it's working by pasting in the text from the readme.

For reference, the character causing me trouble was ?.

For a sanity check, tap your right arrow key over a range of text containing an invisible character, and you'll need to right-arrow twice to move past the character.

I'm also using the following custom regex string (which I don't fully grok):

{
    // there's an extra range in use [^\\x00-\\x7F]
    // also, don't highlight spaces at the end of the line (my settings take care of that)
    "highlighter_regex": "(\t+ +)|( +\t+)|[^\\x00-\\x7F]|[\u2026\u2018\u2019\u201c\u201d\u2013\u2014]"
}

According to Wikipedia:

A segmentation fault occurs when a program attempts to access a memory location that it is not allowed to access, or attempts to access a memory location in a way that is not allowed (for example, attempting to write to a read-only location, or to overwrite part of the operating system).

One major point about Yield keyword is Lazy Execution. Now what I mean by Lazy Execution is to execute when needed. A better way to put it is by giving an example

Example: Not using Yield i.e. No Lazy Execution.

public static IEnumerable<int> CreateCollectionWithList()
{
    var list =  new List<int>();
    list.Add(10);
    list.Add(0);
    list.Add(1);
    list.Add(2);
    list.Add(20);

    return list;
}

Example: using Yield i.e. Lazy Execution.

public static IEnumerable<int> CreateCollectionWithYield()
{
    yield return 10;
    for (int i = 0; i < 3; i++) 
    {
        yield return i;
    }

    yield return 20;
}

Now when I call both methods.

var listItems = CreateCollectionWithList();
var yieldedItems = CreateCollectionWithYield();

you will notice listItems will have a 5 items inside it (hover your mouse on listItems while debugging). Whereas yieldItems will just have a reference to the method and not the items. That means it has not executed the process of getting items inside the method. A very efficient a way of getting data only when needed. Actual implementation of yield can seen in ORM like Entity Framework and NHibernate etc.

i have made a github repository to show what i think is a good (or best practices) startup project structure...

• Clean War project without WEB-INF/lib because dependencies are in EAR/lib folder.
• Clean Ear project.
• Minimal deployment descriptors for Java EE7
• No Local EJB Interface because @LocalBean is sufficient.

In a very simple words any value which has a definite size can be treated as a value type.

If the database engine for tables differ you will get this error so change them to InnoDB

ALTER TABLE my_table ENGINE = InnoDB;

You don't appear to understand what still reachable means.

Anything still reachable is not a leak. You don't need to do anything about it.

You can use these classes

input-lg

input

and

input-sm

for input fields and replace input with btn for buttons.

Check this documentation http://getbootstrap.com/getting-started/#migration

This will change only height of the element, to reduce the width you have to use grid system classes like col-xs-* col-md-* col-lg-*.

Example col-md-3. See doc here http://getbootstrap.com/css/#grid

I use following in one of my common header in the project that covers all bases:

#define _USE_MATH_DEFINES
#include <cmath>

#ifndef M_PI
#define M_PI (3.14159265358979323846)
#endif

#ifndef M_PIl
#define M_PIl (3.14159265358979323846264338327950288)
#endif

On a side note, all of below compilers define M_PI and M_PIl constants if you include <cmath>. There is no need to add `#define _USE_MATH_DEFINES which is only required for VC++.

x86 GCC 4.4+
ARM GCC 4.5+
x86 Clang 3.0+

double supports Infinity

double inf = Double.POSITIVE_INFINITY;
System.out.println(inf + 5);
System.out.println(inf - inf); // same as Double.NaN
System.out.println(inf * -1); // same as Double.NEGATIVE_INFINITY

prints

Infinity
NaN
-Infinity

note: Infinity - Infinity is Not A Number.

You can add any php file in under your active themes folder like (/wp-content/themes/your_active_theme/) and then you can go to add new page from wp-admin and select this page template from page template options.

<?php
/*
 Template Name: Your Template Name
 */
?>

And there is one other way like you can include your file in functions.php and create shortcode from that and then you can put that shortcode in your page like this.

// CODE in functions.php 

function abc(){
 include_once('your_file_name.php');
}
add_shortcode('abc' , 'abc');

And then you can use this shortcode in wp-admin side page like this [abc].

I made a helper interface for this using the holder pattern.

public interface StyleHolder<V extends View> {
    void applyStyle(V view);
}

Now for every style you want to use pragmatically just implement the interface, for example:

public class ButtonStyleHolder implements StyleHolder<Button> {

    private final Drawable background;
    private final ColorStateList textColor;
    private final int textSize;

    public ButtonStyleHolder(Context context) {
        TypedArray ta = context.obtainStyledAttributes(R.style.button, R.styleable.ButtonStyleHolder);

        Resources resources = context.getResources();

        background = ta.getDrawable(ta.getIndex(R.styleable.ButtonStyleHolder_android_background));

        textColor = ta.getColorStateList(ta.getIndex(R.styleable.ButtonStyleHolder_android_textColor));

        textSize = ta.getDimensionPixelSize(
                ta.getIndex(R.styleable.ButtonStyleHolder_android_textSize),
                resources.getDimensionPixelSize(R.dimen.standard_text_size)
        );

        // Don't forget to recycle!
        ta.recycle();
    }

    @Override
    public void applyStyle(Button btn) {
        btn.setBackground(background);
        btn.setTextColor(textColor);
        btn.setTextSize(TypedValue.COMPLEX_UNIT_PX, textSize);
    }
}

Declare a stylable in your attrs.xml, the styleable for this example is:

<declare-styleable name="ButtonStyleHolder">
    <attr name="android:background" />
    <attr name="android:textSize" />
    <attr name="android:textColor" />
</declare-styleable>

Here is the style declared in styles.xml:

<style name="button">
    <item name="android:background">@drawable/button</item>
    <item name="android:textColor">@color/light_text_color</item>
    <item name="android:textSize">@dimen/standard_text_size</item>
</style>

And finally the implementation of the style holder:

Button btn = new Button(context);    
StyleHolder<Button> styleHolder = new ButtonStyleHolder(context);
styleHolder.applyStyle(btn);

I found this very helpful as it can be easily reused and keeps the code clean and verbose, i would recommend using this only as a local variable so we can allow the garbage collector to do its job once we're done with setting all the styles.

1. Object* o; o = new Object();

2. Object* o = new Object();

Both these statement creates the object in the heap memory since you are creating the object using "new".

To be able to make the object creation happen in the stack, you need to follow this:

Object o;
Object *p = &o;

Suppose

$row=mysql_fetch_row($rc)
and if you want to check if row[8] is null then do
$field=$row[8];
   if($field)
echo "";
else
 echo ""; 

Try this....

$(window).resize(function() {
    $("#dialog").dialog("option", "position", "center");
});

Correlated Subquery is a sub-query that uses values from the outer query. In this case the inner query has to be executed for every row of outer query.

See example here http://en.wikipedia.org/wiki/Correlated_subquery

Simple subquery doesn't use values from the outer query and is being calculated only once:

SELECT id, first_name 
FROM student_details 
WHERE id IN (SELECT student_id
FROM student_subjects 
WHERE subject= 'Science'); 

CoRelated Subquery Example -

Query To Find all employees whose salary is above average for their department

 SELECT employee_number, name
       FROM employees emp
       WHERE salary > (
         SELECT AVG(salary)
           FROM employees
           WHERE department = emp.department);

I win the award for dumbest cause of the "No such module" error. In my case I build the included framework by hand, and copy it into my project directory. My framework search paths were set correctly, and the framework was added to the project correctly.

When I archived the framework I was building, I used "Show in Finder" to take me to the release folder in derived data. But I didn't noticed that the folder contains only an alias to the framework, not the framework itself. The original framework remained in my derived data directory, so later when I cleared derived data the framework was deleted, but my project didn't know that.

Re-archiving the framework, following the alias to the actual framework, and copying that to my project directory worked.

In Ruby, the Windows version anyways, I just checked and __FILE__ does not contain the full path to the file. Instead it contains the path to the file relative to where it's being executed from.

In PHP __FILE__ is the full path (which in my opinion is preferable). This is why, in order to make your paths portable in Ruby, you really need to use this:

File.expand_path(File.dirname(__FILE__) + "relative/path/to/file")

I should note that in Ruby 1.9.1 __FILE__ contains the full path to the file, the above description was for when I used Ruby 1.8.7.

In order to be compatible with both Ruby 1.8.7 and 1.9.1 (not sure about 1.9) you should require files by using the construct I showed above.

For Those Running on Older Hardware:

You may get this same error due to having an older CPU using tensorflow-gpu 1.6.

If your cpu was made before 2011, then your max tensorflow-gpu version is 1.5.

Tensorflow 1.6 requires AVX instructions on your cpu. Verified here: Tensorflow Github docs

AVX enabled CPUs: Wiki AVX CPUs

What I did in my conda environment for tensorflow:

pip install --ignore-installed --upgrade tensorflow-gpu==1.5

You can use the button :

1 - make the text empty

2 - set the background for it

+3 - you can use the selector to more useful and nice button

About the imagebutton you can set the image source and the background the same picture and it must be (*.png) when you do it you can make any design for the button

and for more beauty button use the selector //just Google it ;)

As mentioned by Seeker, the problem could have been that you setup the click() function too soon. From your code snippet, we cannot know where you placed the script and whether it gets run at the right time.

An important point is to run such scripts after the document is ready. This is done by placing the click() initialization within that other function as in:

jQuery(document).ready(function()
  {
    jQuery("body").click(function()
      {
        // ... your click code here ...
      });
  });

This is usually the best method, especially if you include your JavaScript code in your <head> tag. If you include it at the very bottom of the page, then the ready() function is less important, but it may still be useful.

Swap using Bitwise

let a = 10;
let b = 20;
a ^= b;
y ^= a;
a ^= b;

Single line Swap "using Array"

[a, b] = [b, a]

Replace Null Values as Empty: ISNULL('Value','')

Replace Null Values as 0: ISNULL('Value',0)

Here's example with simple object exporting.

var MyScreen = {

    /* ... */

    width : function (percent){

        return window.innerWidth / 100 * percent

    }

    height : function (percent){

        return window.innerHeight / 100 * percent

    }


};

export default MyScreen

In main file (Use when you don't want and don't need to create new instance) and it is not global you will import this only when it needed :

import MyScreen from "./module/screen";
console.log( MyScreen.width(100) );

var query = source.GroupBy(x => new { x.Column1, x.Column2 });

DateTime.remove({}, callback) The empty object will match all of them.

They can be differentiated with where they are coming from or which developers they're targeting mainly.

Groovy is a bit like scripting version of Java. Long time Java programmers feel at home when building agile applications backed by big architectures. Groovy on Grails is, as the name suggests similar to the Rails framework. For people who don't want to bother with Java's verbosity all the time.

Scala is an object oriented and functional programming language and Ruby or Python programmers may feel more closer to this one. It employs quite a lot of common good ideas found in these programming languages.

Clojure is a dialect of the Lisp programming language so Lisp, Scheme or Haskell developers may feel at home while developing with this language.

matcher.find() does not find all matches, only the next match.

Solution for Java 9+

long matches = matcher.results().count();

Solution for Java 8 and older

You'll have to do the following. (Starting from Java 9, there is a nicer solution)

int count = 0;
while (matcher.find())
    count++;

Btw, matcher.groupCount() is something completely different.

Complete example:

import java.util.regex.*;

class Test {
    public static void main(String[] args) {
        String hello = "HelloxxxHelloxxxHello";
        Pattern pattern = Pattern.compile("Hello");
        Matcher matcher = pattern.matcher(hello);

        int count = 0;
        while (matcher.find())
            count++;

        System.out.println(count);    // prints 3
    }
}

Handling overlapping matches

When counting matches of aa in aaaa the above snippet will give you 2.

aaaa
aa
  aa

To get 3 matches, i.e. this behavior:

aaaa
aa
 aa
  aa

You have to search for a match at index <start of last match> + 1 as follows:

String hello = "aaaa";
Pattern pattern = Pattern.compile("aa");
Matcher matcher = pattern.matcher(hello);

int count = 0;
int i = 0;
while (matcher.find(i)) {
    count++;
    i = matcher.start() + 1;
}

System.out.println(count);    // prints 3

Load testing = putting a specified amount of load on the server for certain amount of time. 100 simultaneous users for 10 minutes. Ensure stability of software. Stress testing = increasing the amount of load steadily until the software crashes. 10 simultaneous users increasing every 2 minutes until the server crashes.

To make a comparison to weight lifting: You "max" your weight to see what you can do for 1 rep (stress testing) and then on regular workouts you do 85% of your max value for 3 sets of 10 reps (load testing)

You also need to include the Log4J JAR file in the classpath.

Note that slf4j-log4j12-1.6.4.jar is only an adapter to make it possible to use Log4J via the SLF4J API. It does not contain the actual implementation of Log4J.

I Resolved it by cloning my project directly into Eclipse from GIT,

Initially I was cloning it at specific location on file system then importing it as existing project into Eclipse.

You can also use ls with grep or egrep and put it in your profile as an alias:

ls -l | egrep -v '^d'
ls -l | grep -v '^d'

Anwer is here How to dynamically add a style for text-align using jQuery

This works for me on the device (not simulator). Make sure you add the systemconfiguration framework.

#import <SystemConfiguration/CaptiveNetwork.h>

+ (NSString *)currentWifiSSID {
    // Does not work on the simulator.
    NSString *ssid = nil;
    NSArray *ifs = (__bridge_transfer id)CNCopySupportedInterfaces();
    for (NSString *ifnam in ifs) {
        NSDictionary *info = (__bridge_transfer id)CNCopyCurrentNetworkInfo((__bridge CFStringRef)ifnam);
        if (info[@"SSID"]) {
            ssid = info[@"SSID"];
        }
    }
    return ssid;
}

I wasn't able to fix the problem OpenCV either, but a video4linux (V4L2) workaround does work with OpenCV when using Linux. At least, it does on my Raspberry Pi with Rasbian and my cheap webcam. This is not as solid, light and portable as you'd like it to be, but for some situations it might be very useful nevertheless.

Make sure you have the v4l2-ctl application installed, e.g. from the Debian v4l-utils package. Than run (before running the python application, or from within) the command:

v4l2-ctl -d /dev/video1 -c exposure_auto=1 -c exposure_auto_priority=0 -c exposure_absolute=10

It overwrites your camera shutter time to manual settings and changes the shutter time (in ms?) with the last parameter to (in this example) 10. The lower this value, the darker the image.

I realize this question was asked and answered a long time ago, but the answers don't give what I feel is the simplest solution. It's almost always a good idea to avoid loops whenever possible, and matplotlib's plot is capable of plotting multiple lines with one command. If x and y are arrays, then plot draws one line for every column.

In your case, you can do the following:

x=np.array([-1 ,0.5 ,1,-0.5])
xx = np.vstack([x[[0,2]],x[[1,3]]])
y=np.array([ 0.5,  1, -0.5, -1])
yy = np.vstack([y[[0,2]],y[[1,3]]])
plt.plot(xx,yy, '-o')

Have a long list of x's and y's, and want to connect adjacent pairs?

xx = np.vstack([x[0::2],x[1::2]])
yy = np.vstack([y[0::2],y[1::2]])

Want a specified (different) color for the dots and the lines?

plt.plot(xx,yy, '-ok', mfc='C1', mec='C1')

You can do so by creating an array of dtype=object. If you try to assign a long string to a normal numpy array, it truncates the string:

>>> a = numpy.array(['apples', 'foobar', 'cowboy'])
>>> a[2] = 'bananas'
>>> a
array(['apples', 'foobar', 'banana'], 
      dtype='|S6')

But when you use dtype=object, you get an array of python object references. So you can have all the behaviors of python strings:

>>> a = numpy.array(['apples', 'foobar', 'cowboy'], dtype=object)
>>> a
array([apples, foobar, cowboy], dtype=object)
>>> a[2] = 'bananas'
>>> a
array([apples, foobar, bananas], dtype=object)

Indeed, because it's an array of objects, you can assign any kind of python object to the array:

>>> a[2] = {1:2, 3:4}
>>> a
array([apples, foobar, {1: 2, 3: 4}], dtype=object)

However, this undoes a lot of the benefits of using numpy, which is so fast because it works on large contiguous blocks of raw memory. Working with python objects adds a lot of overhead. A simple example:

>>> a = numpy.array(['abba' for _ in range(10000)])
>>> b = numpy.array(['abba' for _ in range(10000)], dtype=object)
>>> %timeit a.copy()
100000 loops, best of 3: 2.51 us per loop
>>> %timeit b.copy()
10000 loops, best of 3: 48.4 us per loop

I don't think converting to a tuple is the right answer. You need go and look at where you are calling the function and make sure that c is a list of list of strings, or whatever you designed this function to work with

For example you might get this error if you passed [c] to the function instead of c

I would suggest you go for bulk insert as suggested in this article : Bulk Insertion of Data Using C# DataTable and SQL server OpenXML function

require(gdata)
keep(object_1,...,object_n,sure=TRUE)
ls()

John's answer is 99% correct. I found that (at least in my configuration), you have to open the Build settings inspector for the PROJECT. The build settings for the target do not contain "Code Signing Entitlements". Perhaps this doesn't make a difference if you have only one target in your project. But if you have multiple targets, you need to go to the project build settings. In any case, after doing what John said, my ad-hoc distribution build worked perfectly.

Delivering email can be like black magic sometimes. The reverse DNS is really important.

I have found it to be very helpful to carefully track NDRs. I direct all of my NDRs to a single address and I have a windows service parsing them out (Google ListNanny). I put as much information from the NDR as I can into a database, and then I run reports on it to see if I have suddenly started getting blocked by a certain domain. Also, you should avoid sending emails to addresses that were previously marked as NDR, because that's generally a good indication of spam.

If you need to send out a bunch of customer service emails at once, it's best to put a delay in between each one, because if you send too many nearly identical emails to one domain at a time, you are sure to wind up on their blacklist.

Some domains are just impossible to deliver to sometimes. Comcast.net is the worst.

Make sure your IPs aren't listed on sites like http://www.mxtoolbox.com/blacklists.aspx.

I think if you want to use extension methods you need to use the GroupJoin

var query =
    people.GroupJoin(pets,
                     person => person,
                     pet => pet.Owner,
                     (person, petCollection) =>
                        new { OwnerName = person.Name,
                              Pet = PetCollection.Select( p => p.Name )
                                                 .DefaultIfEmpty() }
                    ).ToList();

You may have to play around with the selection expression. I'm not sure it would give you want you want in the case where you have a 1-to-many relationship.

I think it's a little easier with the LINQ Query syntax

var query = (from person in context.People
             join pet in context.Pets on person equals pet.Owner
             into tempPets
             from pets in tempPets.DefaultIfEmpty()
             select new { OwnerName = person.Name, Pet = pets.Name })
            .ToList();

A well-explained answer is already given by @mkobit, but I will add a big picture of the range key and hash key.

In a simple words range + hash key = composite primary key CoreComponents of Dynamodb

A primary key is consists of a hash key and an optional range key. Hash key is used to select the DynamoDB partition. Partitions are parts of the table data. Range keys are used to sort the items in the partition, if they exist.

So both have a different purpose and together help to do complex query. In the above example hashkey1 can have multiple n-range. Another example of range and hashkey is game, userA(hashkey) can play Ngame(range)

The Music table described in Tables, Items, and Attributes is an example of a table with a composite primary key (Artist and SongTitle). You can access any item in the Music table directly, if you provide the Artist and SongTitle values for that item.

A composite primary key gives you additional flexibility when querying data. For example, if you provide only the value for Artist, DynamoDB retrieves all of the songs by that artist. To retrieve only a subset of songs by a particular artist, you can provide a value for Artist along with a range of values for SongTitle.

One way to get this error is trying to add a usercontrol to a form while the project is set to compile as x64. Visual Studio throws the unhelpful: "Failed to load toolbox item . It will be removed from the toolbox."

Workaround is to design with "Any CPU" and compile to x64 as necessary.

The current HTML5 draft also allows ommitting the href attribute completely.

If the a element has no href attribute, then the element represents a placeholder for where a link might otherwise have been placed, if it had been relevant.

To answer your question: Yes it's valid.

The best way to accomplish this is by simply adding "href" to the link button like below.

<asp:LinkButton runat="server" id="SomeLinkButton" href="url" CssClass="btn btn-primary btn-sm">Button Text</asp:LinkButton>

Using javascript, or doing this programmatically in the page_load, will work as well but is not the best way to go about doing this.

You will get this result:

<a id="MainContent_ctl00_SomeLinkButton" class="btn btn-primary btn-sm" href="url" href="javascript:__doPostBack(&#39;ctl00$MainContent$ctl00$lSomeLinkButton&#39;,&#39;&#39;)">Button Text</a>

You can also get the same results by using using a regular <a href="" class=""></a>.

Essentially the same as Mike Ramirez's answer, but simpler and closer in stylistics to django standard get_absolute_url method:

from django.urls import reverse

def get_admin_url(self):
    return reverse('admin:%s_%s_change' % (self._meta.app_label, self._meta.model_name),
                   args=[self.id])

I've noticed that if you set the theme in the AndroidManifest, it seems to get rid of that short time where you can see the action bar. So, try adding this to your manifest:

<android:theme="@android:style/Theme.NoTitleBar">

Just add it to your application tag to apply it app-wide.

You can (should) use CROSS JOIN. Following query will be equivalent to yours:

SELECT 
   table1.columnA
 , table2.columnA
FROM table1 
CROSS JOIN table2
WHERE table1.columnA = 'Some value'

or you can even use INNER JOIN with some always true conditon:

FROM table1 
INNER JOIN table2 ON 1=1

You needed to iconv your source.

That said, the T_EX-based compiler invoked by latex doesn't really support variable-length encodings; it needs big libraries that tell it that certain bytes go together. Xelatex is Unicode-aware and works much better.

Many ways this can be achieved.

Simple approach should be taking Substring of an input string.

var result = input.Substring(input.Length - 3);

Another approach using Regular Expression to extract last 3 characters.

var result = Regex.Match(input,@"(.{3})\s*$");

Working Demo

"my, tags are, in here".split(/[ ,]+/)

the result is :

["my", "tags", "are", "in", "here"]

The button can be Disabled in Swift 4 by the code

@IBAction func yourButtonMethodname(sender: UIButon) {
 yourButton.isEnabled = false 
}

Although a bit late in posting an answer, here is an alternative approach without using margins.

<style>
    #divMain { width: 500px; }
    #div1 { width: 100px; float: left; background-color: #fcc; }
    #div2 { overflow:hidden; background-color: #cfc; }
    #div3 { width: 100px; float: right; background-color: #ccf; }
</style>

<div id="divMain">
    <div id="div1">
        div 1
    </div>
    <div id="div3">
        div 3
    </div>
    <div id="div2">
        div 2<br />bit taller
    </div>
</div>

This method works like magic, but here is an explanation :)\

Fiddle with a similar sample here.

To clarify there is no such thing as a mutable string in C# (or .NET in general). Other langues support mutable strings (string which can change) but the .NET framework does not.

So the correct answer to your question is ALL string are immutable in C#.

string has a specific meaning. "string" lowercase keyword is merely a shortcut for an object instantiated from System.String class. All objects created from string class are ALWAYS immutable.

If you want a mutable representation of text then you need to use another class like StringBuilder. StringBuilder allows you to iteratively build a collection of 'words' and then convert that to a string (once again immutable).

Add to your settings.py:

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'handlers': {
        'file': {
            'level': 'DEBUG',
            'class': 'logging.FileHandler',
            'filename': 'debug.log',
        },
    },
    'loggers': {
        'django': {
            'handlers': ['file'],
            'level': 'DEBUG',
            'propagate': True,
        },
    },
}

And it will create a file called debug.log in the root of your. https://docs.djangoproject.com/en/1.10/topics/logging/

An array is a structure with a certain size. You can use dynamic arrays in vba that you can shrink or grow using ReDim but you can't remove elements in the middle. It's not clear from your sample how your array functionally works or how you determine the index position (eachHdr) but you basically have 3 options

(A) Write a custom 'delete' function for your array like (untested)

Public Sub DeleteElementAt(Byval index As Integer, Byref prLst as Variant)
       Dim i As Integer

        ' Move all element back one position
        For i = index + 1 To UBound(prLst)
            prLst(i - 1) = prLst(i)
        Next

        ' Shrink the array by one, removing the last one
        ReDim Preserve prLst(Len(prLst) - 1)
End Sub

(B) Simply set a 'dummy' value as the value instead of actually deleting the element

If prLst(eachHdr) = "0" Then        
   prLst(eachHdr) = "n/a"
End If

(C) Stop using an array and change it into a VBA.Collection. A collection is a (unique)key/value pair structure where you can freely add or delete elements from

Dim prLst As New Collection

It is possible and you don't need to code it on your own.

Just set the ringer volume to zero and vibration to none if incomingNumber equals an empty string. Thats it ...

Its just done for you with the application Nostalk from Android Market. Just give it a try ...

First of all, link_to is a html tag helper, its second argument is the url, followed by html_options. What you would like is to pass account_id as a url parameter to the path. If you have set up named routes correctly in routes.rb, you can use path helpers.

link_to "+ Service", new_my_service_path(:account_id => acct.id)

I think the best practice is to pass model values as a param nested within :

link_to "+ Service", new_my_service_path(:my_service => { :account_id => acct.id })

# my_services_controller.rb
def new
  @my_service = MyService.new(params[:my_service])
end

And you need to control that account_id is allowed for 'mass assignment'. In rails 3 you can use powerful controls to filter valid params within the controller where it belongs. I highly recommend.

http://apidock.com/rails/ActiveModel/MassAssignmentSecurity/ClassMethods

Also note that if account_id is not freely set by the user (e.g., a user can only submit a service for the own single account_id, then it is better practice not to send it via the request, but set it within the controller by adding something like:

@my_service.account_id = current_user.account_id 

You can surely combine the two if you only allow users to create service on their own account, but allow admin to create anyone's by using roles in attr_accessible.

hope this helps

You need to read the file in chunks of suitable size:

def md5_for_file(f, block_size=2**20):
    md5 = hashlib.md5()
    while True:
        data = f.read(block_size)
        if not data:
            break
        md5.update(data)
    return md5.digest()

NOTE: Make sure you open your file with the 'rb' to the open - otherwise you will get the wrong result.

So to do the whole lot in one method - use something like:

def generate_file_md5(rootdir, filename, blocksize=2**20):
    m = hashlib.md5()
    with open( os.path.join(rootdir, filename) , "rb" ) as f:
        while True:
            buf = f.read(blocksize)
            if not buf:
                break
            m.update( buf )
    return m.hexdigest()

The update above was based on the comments provided by Frerich Raabe - and I tested this and found it to be correct on my Python 2.7.2 windows installation

I cross-checked the results using the 'jacksum' tool.

jacksum -a md5 <filename>

http://www.jonelo.de/java/jacksum/

Use vars()

class Foo(object):
    def __init__(self):
        self.a = 1
        self.b = 2

vars(Foo()) #==> {'a': 1, 'b': 2}
vars(Foo()).keys() #==> ['a', 'b']

You should use profiles.

<profiles>
    <profile>
        <id>otherOutputDir</id>
        <build>
            <directory>yourDirectory</directory>
        </build>
    </profile>
</profiles>

And start maven with your profile

mvn compile -PotherOutputDir

If you really want to define your directory from the command line you could do something like this (NOT recommended at all) :

<properties>
    <buildDirectory>${project.basedir}/target</buildDirectory>
</properties>

<build>
    <directory>${buildDirectory}</directory>
</build>

And compile like this :

mvn compile -DbuildDirectory=test

That's because you can't change the target directory by using -Dproject.build.directory

In Python 3.4+:

import html

html.unescape(your_string)

Yes. std::exception is the base exception class in the C++ standard library. You may want to avoid using strings as exception classes because they themselves can throw an exception during use. If that happens, then where will you be?

boost has an excellent document on good style for exceptions and error handling. It's worth a read.

I'm assume you cannot get css working for your button using anchor tag. So you need to override the css styles which are being overwritten by other elements using !important property.

HTML

<a href="#" class="selected_btn" data-role="button">Button name</a>

CSS

.selected_btn
{
    border:1px solid red;
    text-decoration:none;
    font-family:helvetica;
    color:red !important;            
    background:url('http://www.lessardstephens.com/layout/images/slideshow_big.png') repeat-x;
}

Here is the demo

$('.launchConfirm').on('click', function (e) {
    $('#confirm')
        .modal({ backdrop: 'static', keyboard: false })
        .one('click', '#delete', function (e) {
            //delete function
        });
});

FIDDLE

For your button:

<button class='btn btn-danger btn-xs launchConfirm' type="button" name="remove_levels"><span class="fa fa-times"></span> delete</button></td>

None of the above worked for me. This is what worked for me on Enzyme ^3.1.1:

input.instance().props.onChange(({ target: { value: '19:00' } }));

Here is the rest of the code for context:

const fakeHandleChangeValues = jest.fn();
  const fakeErrors = {
    errors: [{
      timePeriod: opHoursData[0].timePeriod,
      values: [{
        errorIndex: 2,
        errorTime: '19:00',
      }],
    }],
    state: true,
  };
const wrapper = mount(<AccessibleUI
    handleChangeValues={fakeHandleChangeValues}
    opHoursData={opHoursData}
    translations={translationsForRendering}
  />);
const input = wrapper.find('#input-2').at(0);
input.instance().props.onChange(({ target: { value: '19:00' } }));
expect(wrapper.state().error).toEqual(fakeErrors);

yes, there is:

object[] x = new object[2];

x[0] = new { firstName = "john", lastName = "walter" };
x[1] = new { brand = "BMW" };

you were practically there, just the declaration of the anonymous types was a little off.

There's also solution for Node JS app. CORS Anywhere is a NodeJS proxy which adds CORS headers to the proxied request.

The url to proxy is literally taken from the path, validated and proxied. The protocol part of the proxied URI is optional, and defaults to "http". If port 443 is specified, the protocol defaults to "https".

This package does not put any restrictions on the http methods or headers, except for cookies. Requesting user credentials is disallowed. The app can be configured to require a header for proxying a request, for example to avoid a direct visit from the browser. https://robwu.nl/cors-anywhere.html

The simple answer for this one is that you have an undeclared (null) variable. In this case it is $md5. From the comment you put this needed to be declared elsewhere in your code

$md5 = new-object -TypeName System.Security.Cryptography.MD5CryptoServiceProvider

The error was because you are trying to execute a method that does not exist.

PowerShell by default allows this to happen as defined its StrictMode

When Set-StrictMode is off, uninitialized variables (Version 1) are assumed to have a value of 0 (zero) or $Null, depending on type. References to non-existent properties return $Null, and the results of function syntax that is not valid vary with the error. Unnamed variables are not permitted.

The code below was tested on iPhone, iPad (iOS13), Safari (Catalina). It was able to autoplay the YouTube video on all devices. Make sure the video is muted and the playsinline parameter is on. Those are the magic parameters that make it work.

Your UITableViewDelegate should implement tableView:heightForRowAtIndexPath:

Objective-C

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return [indexPath row] * 20;
}

Swift 5

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return indexPath.row * 20
}

You will probably want to use NSString's sizeWithFont:constrainedToSize:lineBreakMode: method to calculate your row height rather than just performing some silly math on the indexPath :)

I'd do (added caching):

var bbx = $("#blackbox");
 bbx.css('background-color') === 'rgb(255, 192, 203)' ? bbx.css('background','black') : bbx.css('background','pink')

wroking fiddle (new AGAIN): http://jsfiddle.net/6nar4/37/

I had to change the first operator as css() returns the rgb value of the color

I want to add one Hello, World! example that explains the basics of slices for the very beginners. It helped me a lot.

Let's have a list with six values ['P', 'Y', 'T', 'H', 'O', 'N']:

+---+---+---+---+---+---+
| P | Y | T | H | O | N |
+---+---+---+---+---+---+
  0   1   2   3   4   5

Now the simplest slices of that list are its sublists. The notation is [<index>:<index>] and the key is to read it like this:

[ start cutting before this index : end cutting before this index ]

Now if you make a slice [2:5] of the list above, this will happen:

        |           |
+---+---|---+---+---|---+
| P | Y | T | H | O | N |
+---+---|---+---+---|---+
  0   1 | 2   3   4 | 5

You made a cut before the element with index 2 and another cut before the element with index 5. So the result will be a slice between those two cuts, a list ['T', 'H', 'O'].

By the Spring guys, used for Grails reloading but works with Java too:

I think, from my own experience on problems with more advanced data structures, that the most important thing you can do here, is to get a good knowledge on the general concept of tress as data structures. If you understand the basic mechanism behind the concept it will be quite easy to implement the solution that fits your problem. There are a lot of good sources out there describing the concept. What "saved" me years ago on this particular problem was section 2.3 in "The Art of Computer Programming".

It won't be caught by the second catch block. Each Exception is caught only when inside a try block. You can nest tries though (not that it's a good idea generally):

try {
    doSomething();
} catch (IOException) {
   try {
       doSomething();
   } catch (IOException e) {
       throw new ApplicationException("Failed twice at doSomething" +
       e.toString());
   }          
} catch (Exception e) {
}

Just use NVM(Node Version Manager) - https://github.com/creationix/nvm

It has become the standard for managing Node.js.

When you need a new version:

nvm install NEW_VER
nvm use XXX

If something goes wrong you can always go back with

nvm use OLD_VER

WinMount provides an easiest way to mount VMDK as a virtual disk. You can read or write to the vmdk file without loading the virtual system. Here shows you how to do: http://www.winmount.com/mount_vmdk.html

There are two approaches which are not mentioned above, but both of which solve the problem in a way which complies with PEP 8 and allow you to make better use of your space. They are:

msg = (
    'This message is so long, that it requires '
    'more than {x} lines.{sep}'
    'and you may want to add more.').format(
        x=x, sep=2*'\n')
print(msg)

Notice how the parentheses are used to allow us not to add plus signs between pure strings, and spread the result over multiple lines without the need for explicit line continuation '\' (ugly and cluttered). The advantages are same with what is described below, the difference is that you can do it anywhere. Compared to the previous alternative, it is visually better when inspecting code, because it outlines the start and end of msg clearly (compare with msg += one every line, which needs one additional thinking step to deduce that those lines add to the same string - and what if you make a typo, forgetting a + on one random line ?).

Regarding this approach, many times we have to build a string using iterations and checks within the iteration body, so adding its pieces within the function call, as shown later, is not an option.

A close alternative is:

msg = 'This message is so long, that it requires '
msg += 'many lines to write, one reason for that\n'
msg += 'is that it contains numbers, like this '
msg += 'one: ' + str(x) +', which take up more space\n'
msg += 'to insert. Note how newlines are also included '
msg += 'and can be better presented in the code itself.'
print(msg)

Though the first is preferable.

The other approach is like the previous ones, though it starts the message on the line below the print. The reason for this is to gain space on the left, otherwise the print( itself "pushes" you to the right. This consumption of indentation is the inherited by the rest of the lines comprising the message, because according to PEP 8 they must align with the opening parenthesis of print above them. So if your message was already long, this way it's forced to be spread over even more lines.

Contrast:

raise TypeError('aaaaaaaaaaaaaaaa' +
                'aaaaaaaaaaaaaaaa' +
                'aaaaaaaaaaaaaaaa')

with this (suggested here):

raise TypeError(
    'aaaaaaaaaaaaaaaaaaaaaaaa' +
    'aaaaaaaaaaaaaaaaaaaaaaaa')

The line spread was reduced. Of course this last approach does no apply so much to print, because it is a short call. But it does apply to exceptions.

A variation you can have is:

raise TypeError((
    'aaaaaaaaaaaaaaaaaaaaaaaa'
    'aaaaaaaaaaaaaaaaaaaaaaaa'
    'aaaaa {x} aaaaa').format(x=x))

Notice how you don't need to have plus signs between pure strings. Also, the indentation guides the reader's eyes, no stray parentheses hanging below to the left. The replacements are very readable. In particular, such an approach makes writing code that generates code or mathematical formulas a very pleasant task.

What about Regex.Replace solution?

myStr = Regex.Replace(myStr, "\s", "")

I believe best practice these days is H/5 * * * *, which means every 5 minutes with a hashing factor to avoid all jobs starting at EXACTLY the same time.

For Loopback3 all the examples given did not work for me, or as fast as using REST API anyway. But it helped me to figure out the exact answer I needed.

{"where":{"arrayAttribute":{ "all" :[String]}}}

Actually maybe you should choose the function update is better.
Here's the document of function update http://api.highcharts.com/highcharts#Series.update

You can just type code like below:

chart.series[0].update({data: [1,2,3,4,5]})

These code will merge the origin option, and update the changed data.

Just to add another option to the mix, there are several useful constants within the string module. While more useful in other cases, they can be used here.

>>> from string import digits
>>> ''.join(c for c in "abc123def456" if c in digits)
'123456'

There are several constants in the module, including:

• ascii_letters (abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ)
• hexdigits (0123456789abcdefABCDEF)

If you are using these constants heavily, it can be worthwhile to covert them to a frozenset. That enables O(1) lookups, rather than O(n), where n is the length of the constant for the original strings.

>>> digits = frozenset(digits)
>>> ''.join(c for c in "abc123def456" if c in digits)
'123456'

If you are missing just one import (the class name has red underline), click and hover the mouse over it, and a blue suggested import statement will appear. If you hit, Alt + Enter at this point, the import will be included in the file and the red underline should disappear.

To produce patch for several commits, you should use format-patch git command, e.g.

git format-patch -k --stdout R1..R2

This will export your commits into patch file in mailbox format.

To generate patch for the last commit, run:

git format-patch -k --stdout HEAD^

Then in another repository apply the patch by am git command, e.g.

git am -3 -k file.patch

See: man git-format-patch and git-am.

I would use the SplFileObject class...

$file = new SplFileObject("filename");
if (!$file->eof()) {
     $file->seek($lineNumber);
     $contents = $file->current(); // $contents would hold the data from line x
}

If you want the jar task to behave normally and also have an additional fatJar task, use the following:

task fatJar(type: Jar) {
    classifier = 'all'
    from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
    with jar
}

The important part is with jar. Without it, the classes of this project are not included.

Try This:

func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
    return UITableViewAutomaticDimension
}

EDIT

func tableView(tableView: UITableView, estimatedHeightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
    return UITableViewAutomaticDimension
}

Swift 4

func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
    return UITableViewAutomaticDimension
}

Swift 4.2

func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
    return UITableView.automaticDimension
}

Define above Both Methods.
It solves the problem.

PS: Top and bottom constraints is required for this to work.

Here is example

These all seem like very complicated answers for a very simple function:

public bool IsWindows7 
{ 
    get 
    { 
        return (Environment.OSVersion.Version.Major == 6 &
            Environment.OSVersion.Version.Minor == 1); 
    } 
}

Well this is the MSDN page that deals with IntPtr.

The first line reads:

A platform-specific type that is used to represent a pointer or a handle.

As to what a pointer or handle is the page goes on to state:

The IntPtr type can be used by languages that support pointers, and as a common means of referring to data between languages that do and do not support pointers.

IntPtr objects can also be used to hold handles. For example, instances of IntPtr are used extensively in the System.IO.FileStream class to hold file handles.

A pointer is a reference to an area of memory that holds some data you are interested in.

A handle can be an identifier for an object and is passed between methods/classes when both sides need to access that object.

FWIW, node.js comes with a shell, try typing in:

node-repl

once you've installed node.js to see it in action. It's pretty standard to install rlwrap to get it to work nicely.

There are two ways to add references using VBA. .AddFromGuid(Guid, Major, Minor) and .AddFromFile(Filename). Which one is best depends on what you are trying to add a reference to. I almost always use .AddFromFile because the things I am referencing are other Excel VBA Projects and they aren't in the Windows Registry.

The example code you are showing will add a reference to the workbook the code is in. I generally don't see any point in doing that because 90% of the time, before you can add the reference, the code has already failed to compile because the reference is missing. (And if it didn't fail-to-compile, you are probably using late binding and you don't need to add a reference.)

If you are having problems getting the code to run, there are two possible issues.

1. In order to easily use the VBE's object model, you need to add a reference to Microsoft Visual Basic for Application Extensibility. (VBIDE)
2. In order to run Excel VBA code that changes anything in a VBProject, you need to Trust access to the VBA Project Object Model. (In Excel 2010, it is located in the Trust Center - Macro Settings.)

Aside from that, if you can be a little more clear on what your question is or what you are trying to do that isn't working, I could give a more specific answer.

As others have answered, scatter() or plot() will generate the plot you want. I suggest two refinements to answers that are already here:

1. Use numpy to create the x-coordinate list and y-coordinate list. Working with large data sets is faster in numpy than using the iteration in Python suggested in other answers.

2. Use pyplot to apply the logarithmic scale rather than operating directly on the data, unless you actually want to have the logs.

   import matplotlib.pyplot as plt
   import numpy as np
   
   data = [(2, 10), (3, 100), (4, 1000), (5, 100000)]
   data_in_array = np.array(data)
   '''
   That looks like array([[     2,     10],
                          [     3,    100],
                          [     4,   1000],
                          [     5, 100000]])
   '''
   
   transposed = data_in_array.T
   '''
   That looks like array([[     2,      3,      4,      5],
                          [    10,    100,   1000, 100000]])
   '''    
   
   x, y = transposed 
   
   # Here is the OO method
   # You could also the state-based methods of pyplot
   fig, ax = plt.subplots(1,1) # gets a handle for the AxesSubplot object
   ax.plot(x, y, 'ro')
   ax.plot(x, y, 'b-')
   ax.set_yscale('log')
   fig.show()
   

I've also used ax.set_xlim(1, 6) and ax.set_ylim(.1, 1e6) to make it pretty.

I've used the object-oriented interface to matplotlib. Because it offers greater flexibility and explicit clarity by using names of the objects created, the OO interface is preferred over the interactive state-based interface.

The latest JDBC MSSQL connectivity driver can be found on JDBC 4.0

The class file should be in the classpath. If you are using eclipse you can easily do the same by doing the following -->

Right Click Project Name --> Properties --> Java Build Path --> Libraries --> Add External Jars

Also as already been pointed out by @Cheeso the correct way to access is jdbc:sqlserver://server:port;DatabaseName=dbname

Meanwhile please find a sample class for accessing MSSQL DB (2008 in my case).

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

public class ConnectMSSQLServer
{
   public void dbConnect(String db_connect_string,
            String db_userid,
            String db_password)
   {
      try {
         Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
         Connection conn = DriverManager.getConnection(db_connect_string,
                  db_userid, db_password);
         System.out.println("connected");
         Statement statement = conn.createStatement();
         String queryString = "select * from SampleTable";
         ResultSet rs = statement.executeQuery(queryString);
         while (rs.next()) {
            System.out.println(rs.getString(1));
         }
         conn.close();
      } catch (Exception e) {
         e.printStackTrace();
      }
   }

   public static void main(String[] args)
   {
      ConnectMSSQLServer connServer = new ConnectMSSQLServer();
      connServer.dbConnect("jdbc:sqlserver://xx.xx.xx.xxxx:1433;databaseName=MyDBName", "DB_USER","DB_PASSWORD");
   }
}

Hope this helps.

Here is an illustration of your first import cycle problem.

                  project/controllers/account
                     ^                    \    
                    /                      \
                   /                        \ 
                  /                         \/
         project/components/mux <--- project/controllers/base

As you can see with my bad ASCII chart is that you are creating an import cycle when project/components/mux imports project/controllers/account. Since Go does not support circular dependencies you get the import cycle not allowed error during compile time.

Use the sepia filter along with hue-rotate, brightness, and saturation to create any color we want.

.colorize-pink {
  filter: brightness(0.5) sepia(1) hue-rotate(-70deg) saturate(5);
}

For simple cases, I would also suggest looking at XmlOutput a fluent interface for building Xml.

XmlOutput is great for simple Xml creation with readable and maintainable code, while generating valid Xml. The orginal post has some great examples.

What this means is that you are trying to print out/output a value which is at least partially uninitialized. Can you narrow it down so that you know exactly what value that is? After that, trace through your code to see where it is being initialized. Chances are, you will see that it is not being fully initialized.

If you need more help, posting the relevant sections of source code might allow someone to offer more guidance.

EDIT

I see you've found the problem. Note that valgrind watches for Conditional jump or move based on unitialized variables. What that means is that it will only give out a warning if the execution of the program is altered due to the uninitialized value (ie. the program takes a different branch in an if statement, for example). Since the actual arithmetic did not involve a conditional jump or move, valgrind did not warn you of that. Instead, it propagated the "uninitialized" status to the result of the statement that used it.

It may seem counterintuitive that it does not warn you immediately, but as mark4o pointed out, it does this because uninitialized values get used in C all the time (examples: padding in structures, the realloc() call, etc.) so those warnings would not be very useful due to the false positive frequency.

This will return TRUE for #VALUE! errors (ERROR.TYPE = 3) and FALSE for anything else.

=IF(ISERROR(A1),ERROR.TYPE(A1)=3)

You can define style rules which only apply to specific elements inside your div with id divContainer like this:

#divContainer input { ... }
#divContainer input[type="radio"] { ... }
#divContainer input[type="text"] { ... }
/* etc */

per your advice, i am using handle and runnables to switch/change the content of the TextView using a "timer". for some reason, when running, the app always skips the second step ("Step Two: fry egg"), and only show the last (third) step ("Step three: serve egg").

TextView t; 
private String sText;

private Handler mHandler = new Handler();

private Runnable mWaitRunnable = new Runnable() {
    public void run() {
        t.setText(sText);
    }
};

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.main);

    mMonster = BitmapFactory.decodeResource(getResources(),
            R.drawable.monster1);

    t=new TextView(this); 
    t=(TextView)findViewById(R.id.TextView01); 

    sText = "Step One: unpack egg";
    t.setText(sText);

    sText = "Step Two: fry egg";        
    mHandler.postDelayed(mWaitRunnable, 3000);

    sText = "Step three: serve egg";
    mHandler.postDelayed(mWaitRunnable, 4000);      
    ...
}

Here is the solution step-by-step:

1. Open up httpd-ssl.conf in path2xampp\apache\conf\extra
2. Look for the line Listen 443
3. Change port number to anything you want. I use 4430. ex. Listen 4430.
4. Replace every 443 string in that file with 4430.
5. Save the file.

mysql> DROP INDEX email ON fuinfo;

where email is the unique key (rather than the column name). You find the name of the unique key by

mysql> SHOW CREATE TABLE fuinfo;

here you see the name of the unique key, which could be email_2, for example. So...

mysql> DROP INDEX email_2 ON fuinfo;

mysql> DESCRIBE fuinfo;

This should show that the index is removed

ChDir "" was the solution for me. I use vba from WORD to launch a python3 script.

Instead of doing file_put_contents(***WebSiteURL***...) you need to use the server path to /cache/lang/file.php (e.g. /home/content/site/folders/filename.php).

You cannot open a file over HTTP and expect it to be written. Instead you need to open it using the local path.

Inspired from some of the answers above that work with base python packages I compared the performance of a few (using Python 3.7.3):

Method 1: ast

import ast
list(map(str.strip, ast.literal_eval(u'[ "A","B","C" , " D"]')))
# ['A', 'B', 'C', 'D']

import timeit
timeit.timeit(stmt="list(map(str.strip, ast.literal_eval(u'[ \"A\",\"B\",\"C\" , \" D\"]')))", setup='import ast', number=100000)
# 1.292875313000195

Method 2: json

import json
list(map(str.strip, json.loads(u'[ "A","B","C" , " D"]')))
# ['A', 'B', 'C', 'D']

import timeit
timeit.timeit(stmt="list(map(str.strip, json.loads(u'[ \"A\",\"B\",\"C\" , \" D\"]')))", setup='import json', number=100000)
# 0.27833264000014424

Method 3: no import

list(map(str.strip, u'[ "A","B","C" , " D"]'.strip('][').replace('"', '').split(',')))
# ['A', 'B', 'C', 'D']

import timeit
timeit.timeit(stmt="list(map(str.strip, u'[ \"A\",\"B\",\"C\" , \" D\"]'.strip('][').replace('\"', '').split(',')))", number=100000)
# 0.12935059100027502

I was disappointed to see what I considered the method with the worst readability was the method with the best performance... there are tradeoffs to consider when going with the most readable option... for the type of workloads I use python for I usually value readability over a slightly more performant option, but as usual it depends.

delete cache using:

    php artisan config:clear
    php artisan config:cache

You are using .index() which will only find the first occurrence of your value in the list. So if you have a value 1.0 at index 2, and at index 9, then .index(1.0) will always return 2, no matter how many times 1.0 occurs in the list.

Use enumerate() to add indices to your loop instead:

def find(lst, a, b):
    result = []
    for i, x in enumerate(lst):
        if x<a or x>b:
            result.append(i)
    return result

You can collapse this into a list comprehension:

def find(lst, a, b):
    return [i for i, x in enumerate(lst) if x<a or x>b]

For French Locale (France) ONLY, be careful because / appears in the date :

echo %DATE%
08/09/2013

For our problem of log file, here is my proposal for French Locale ONLY:

SETLOCAL
set LOGFILE_DATE=%DATE:~6,4%.%DATE:~3,2%.%DATE:~0,2%
set LOGFILE_TIME=%TIME:~0,2%.%TIME:~3,2%
set LOGFILE=log-%LOGFILE_DATE%-%LOGFILE_TIME%.txt
rem log-2014.05.19-22.18.txt
command > %LOGFILE%

You may use the command todos filename to convert to DOS endings, and fromdos filename to convert to UNIX line endings. To install the package on Ubuntu, type sudo apt-get install tofrodos.

Few things to fix here:

1. No parenthesis in class declaration
2. Make the "correct" property as public
3. And then do the selection

Your code will look something like this

List<Answer> answers = new List<Answer>();
/* test
answers.Add(new Answer() { correct = false });
answers.Add(new Answer() { correct = true });
answers.Add(new Answer() { correct = false });
*/
Answer answer = answers.Single(a => a.correct == true);

and the class

class Answer
{
   public bool correct;
}

Wells are dropped from Bootstrap with the version 4.

You can use Cards instead of Wells.

Here is a quick example for how to use new Cards feature:

<div class="card card-inverse" style="background-color: #333; border-color: #333;">
  <div class="card-block">
    <h3 class="card-title">Card Title</h3>
    <p class="card-text">This text will be written on a grey background inside a Card.</p>
    <a href="#" class="btn btn-primary">This is a Button</a>
  </div>
</div>

There is simple command.

mysql -h {hostip} -P {port} -u {username} -p {database}

Example

mysql -h 192.16.16.2 -P 45012 -u rockbook -p rockbookdb

I prefer to make it without delegates and segues. It can be done with custom init or by setting optional values.

1. Custom init

class ViewControllerA: UIViewController {
  func openViewControllerB() {
    let viewController = ViewControllerB(string: "Blabla", completionClosure: { success in
      print(success)
    })
    navigationController?.pushViewController(animated: true)
  }
}

class ViewControllerB: UIViewController {
  private let completionClosure: ((Bool) -> Void)
  init(string: String, completionClosure: ((Bool) -> Void)) {
    self.completionClosure = completionClosure
    super.init(nibName: nil, bundle: nil)
    title = string
  }

  func finishWork() {
    completionClosure()
  }
}

2. Optional vars

class ViewControllerA: UIViewController {
  func openViewControllerB() {
    let viewController = ViewControllerB()
    viewController.string = "Blabla"
    viewController.completionClosure = { success in
      print(success)
    }
    navigationController?.pushViewController(animated: true)
  }
}

class ViewControllerB: UIViewController {
  var string: String? {
    didSet {
      title = string
    }
  }
  var completionClosure: ((Bool) -> Void)?

  func finishWork() {
    completionClosure?()
  }
}

Cshtml files are the ones used by Razor and as stated as answer for this question, their main advantage is that they can be rendered inside unit tests. The various answers to this other topic will bring a lot of other interesting points.

To summarize and explain visually how it works. Code construction is as follows:

par(mar = c(3,2,2,1))
barplot(...all parameters...)
title("Title text", adj = 0.5, line = 0)

explanation:

par(mar = c(low, left, top, right)) - margins of the graph area.

title("text" - title text
      adj  = from left (0) to right (1) with anything in between: 0.1, 0.2, etc...
      line = positive values move title text up, negative - down)

On Windows this should work (note the forwardslash and that the whole path is not quoted and that spaces are allowed)

USE yourdb;

SOURCE D:/My Folder with spaces/Folder/filetoimport.sql;

Even though it's correct to use git rm [FILE], alternatively, you could do git add -u.

According to the git-add documentation:

-u --update

Update the index just where it already has an entry matching [FILE]. This removes as well as modifies index entries to match the working tree, but adds no new files.

If no [FILE] is given when -u option is used, all tracked files in the entire working tree are updated (old versions of Git used to limit the update to the current directory and its subdirectories).

Upon which the index will be refreshed and files will be properly staged.

After placing the jar file in desired location, you need to add the jar file by right click on

Project --> properties --> Java Build Path --> Libraries --> Add Jar.

You might want to look into a Python package manager like pip. If you don't want to use a Python package manager, you should be able to download M2Crypto and build/compile/install over the old installation.

Join string1 with string2 and use KMP algorithm to check whether string2 is present in newly formed string. Because time complexity of KMP is lesser than substr.

Using Float.parseFloat()?

class Test {
    public static void main(String[] args) {
        String s = "3.14";
        float f = Float.parseFloat(s);
        System.out.println(f);
    }
}

Reason and solution-

Everything happens for a reason :)

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-clean-plugin:3.1.0:clean (default-clean) on project

• The reason of this problem is that the target folder is already in use. That means any jar or any war or any application is using that target folder

Solution- 1) Check the war and jar (also check jar if any running in background), terminate it.

2) if u have opened command prompt (cmd), and are using that path to execute the jar, close it or change the path in cmd. This was the reason in my case. Do check this.

Once u do this , u would be able to delete the contents of the target folder and and can also perform maven clean and maven install.

For me this code worked in JavaScript like a charm!

<%= session.getAttribute("variableName")%>

hope it helps...

I was facing the same issue, the funny thing was I had two projects opened on simultaneously, I have changed the wrong app.modules.ts files.

First, check that.

After that change add the following code to the app.module.ts file

import { HttpClientModule } from '@angular/common/http';

After that add the following to the imports array in the app.module.ts file

  imports: [
    HttpClientModule,....
  ],

Now you should be ok!

Take care to provide only 1 setter and getter for any attribute. The best way to approach is to write down the definition of all the attributes then use eclipse generate setter and getter utility rather than doing it manually. The option comes on right click-> source -> Generate Getter and Setter.

Lets say you want to unstage changes upto n commits,

Where commit hashes are as follows:

• h1
• h2 ...
• hn
• hn+1

Then run the following command:
git reset hn

Now the HEAD will be at hn+1. Changes from h1 to hn will be unstaged.

My contribution:

function serializeToJson(serializer){
    var _string = '{';
    for(var ix in serializer)
    {
        var row = serializer[ix];
        _string += '"' + row.name + '":"' + row.value + '",';
    }
    var end =_string.length - 1;
    _string = _string.substr(0, end);
    _string += '}';
    console.log('_string: ', _string);
    return JSON.parse(_string);
}

var params = $('#frmPreguntas input').serializeArray();
params = serializeToJson(params);

Don't forget buckets are region specific. That might be an issue.

Also try using the S3 console to navigate to the actual object, and then click on Copy Path, you will get something like:

s3://<bucket-name>/<path>/object.txt

As long as whatever you are passing it to parses that properly I find that is the safest thing to do.

When I had to solve this problem, I created a hard-coded data dictionary to map between numbers and their associated words. For example, the following might represent a few entries in the dictionary:

{1, "one"}
{2, "two"}
{30, "thirty"}

You really only need to worry about mapping numbers in the 10^0 (1,2,3, etc.) and 10^1 (10,20,30) positions because once you get to 100, you simply have to know when to use words like hundred, thousand, million, etc. in combination with your map. For example, when you have a number like 3,240,123, you get: three million two hundred forty thousand one hundred twenty three.

After you build your map, you need to work through each digit in your number and figure out the appropriate nomenclature to go with it.

Also removing the submodule and then running git submodule init and git submodule update will obviously do the trick, but may not always be appropriate or possible.

Try using a format file since your data file only has 4 columns. Otherwise, try OPENROWSET or use a staging table.

myTestFormatFiles.Fmt may look like:

9.0
4
1       SQLINT        0       3       ","      1     StudentNo      ""
2       SQLCHAR       0       100     ","      2     FirstName      SQL_Latin1_General_CP1_CI_AS
3       SQLCHAR       0       100     ","      3     LastName       SQL_Latin1_General_CP1_CI_AS
4       SQLINT        0       4       "\r\n"   4     Year           "

This tutorial on skipping a column with BULK INSERT may also help.

Your statement then would look like:

USE xta9354
GO
BULK INSERT xta9354.dbo.Students
    FROM 'd:\userdata\xta9_Students.txt' 
    WITH (FORMATFILE = 'C:\myTestFormatFiles.Fmt')

# import msvcrt
import getch

def getPass():
    passwor = ''
    while True:
        x = getch.getch()
        # x = msvcrt.getch().decode("utf-8")
        if x == '\r' or x == '\n':
            break
        print('*', end='', flush=True)
        passwor +=x
    return passwor

print("\nout=", getPass())

msvcrt us only for windows, but getch from PyPI should work for both (I only tested with linux). You can also comment/uncomment the two lines to make it work for windows.

Follow these steps, respectively for rename column migration file.

1- Is there Doctrine/dbal library in your project. If you don't have run the command first

composer require doctrine/dbal

2- create update migration file for update old migration file. Warning (need to have the same name)

php artisan make:migration update_oldFileName_table

for example my old migration file name: create_users_table update file name should : update_users_table

3- update_oldNameFile_table.php

Schema::table('users', function (Blueprint $table) {
$table->renameColumn('from', 'to');
});

'from' my old column name and 'to' my new column name

4- Finally run the migrate command

php artisan migrate

The u prefix means that those strings are unicode rather than 8-bit strings. The best way to not show the u prefix is to switch to Python 3, where strings are unicode by default. If that's not an option, the str constructor will convert from unicode to 8-bit, so simply loop recursively over the result and convert unicode to str. However, it is probably best just to leave the strings as unicode.

set -e stops the execution of a script if a command or pipeline has an error - which is the opposite of the default shell behaviour, which is to ignore errors in scripts. Type help set in a terminal to see the documentation for this built-in command.

What's wrong with Object.assign(target, source) ?

Arrays are still type object in Javascript, so using assign should still reassign any matching keys parsed by the operator as long as matching keys are found, right?

Just spent a good few days trying to get this to work on High Sierra 10.13.1. The gdb 8.1 version from homebrew would not work no matter what I tried. Ended up installing gdb 8.0.1 via macports and this miraculously worked (after jumping through all of the other necessary hoops related to codesigning etc).

One additional issue is that in Eclipse you will get extraneous single quotes around all of your program arguments which can be worked around by providing the arguments inside .gdbinit instead.

Just one extra option, if you want to revert the default behaviour for all textareas in the application, you could add the following to your CSS:

textarea:not([resize="true"]) {
  resize: none !important;
}

And do the following to enable where you want resizing:

<textarea resize="true"></textarea>

Have in mind this solution might not work in all browsers you may want to support. You can check the list of support for resize here: http://caniuse.com/#feat=css-resize

The simplest solution is :

    listView.setTranscriptMode(ListView.TRANSCRIPT_MODE_ALWAYS_SCROLL);
    listView.setStackFromBottom(true);

Kindly use offset-md-4 instead of col-md-offset-4 in bootstrap 4. It's little changes adopted in bootstrap 4.

Beside all the other important aspects already mentioned here, Collections API (e.g. Map interface) is being modified all the time to conform to the "latest and greatest" additions to Java spec.

For example, compare Java 5 Map iterating:

for (Elem elem : map.keys()) {
  elem.doSth();
}

versus the old Hashtable approach:

for (Enumeration en = htable.keys(); en.hasMoreElements(); ) {
  Elem elem = (Elem) en.nextElement();
  elem.doSth();
}

In Java 1.8 we are also promised to be able to construct and access HashMaps like in good old scripting languages:

Map<String,Integer> map = { "orange" : 12, "apples" : 15 };
map["apples"];

Update: No, they won't land in 1.8... :(

Are Project Coin's collection enhancements going to be in JDK8?

Update to angular 4.X.X, there is a new way to mark an option selected:

<select [compareWith]="byId" [(ngModel)]="selectedItem">
  <option *ngFor="let item of items" [ngValue]="item">{{item.name}}
  </option>
</select>

byId(item1: ItemModel, item2: ItemModel) {
  return item1.id === item2.id;
}

As already pointed out by @snishalaka, you can increase the number of inotify watchers.

However, I think the default number is high enough and is only reached when processes are not cleaned up properly. Hence, I simply restarted my computer as proposed on a related github issue and the error message was gone.

The answer is that #1 is technically correct based on the real meaning of the Mega prefix, however (and in life there is always a however) the math for that doesn't come out so nice in base 2, which is how computers count, so #2 is what people really use.

Looping helps:

for row in matrix:
    print ' '.join(row)

or use nested str.join() calls:

print '\n'.join([' '.join(row) for row in matrix])

Demo:

>>> matrix = [['A', 'B', 'C', 'D', 'E'], ['A', 'B', 'C', 'D', 'E'], ['A', 'B', 'C', 'D', 'E'], ['A', 'B', 'C', 'D', 'E'], ['A', 'B', 'C', 'D', 'E']]
>>> for row in matrix:
...     print ' '.join(row)
... 
A B C D E
A B C D E
A B C D E
A B C D E
A B C D E
>>> print '\n'.join([' '.join(row) for row in matrix])
A B C D E
A B C D E
A B C D E
A B C D E
A B C D E

If you wanted to show the rows and columns transposed, transpose the matrix by using the zip() function; if you pass each row as a separate argument to the function, zip() recombines these value by value as tuples of columns instead. The *args syntax lets you apply a whole sequence of rows as separate arguments:

>>> for cols in zip(*matrix):  # transposed
...     print ' '.join(cols)
... 
A A A A A
B B B B B
C C C C C
D D D D D
E E E E E

If you want to be relax for installing libraries for python.

You should using pip, that is python installer package.

To install pip:

1. Download ez_setup.py and then run:

   python ez_setup.py
   

2. Then download get-pip.py and run:

   python get-pip.py
   

3. upgrade installed setuptools by pip:

   pip install setuptools --upgrade
   

   If you got this error:

   Wheel installs require setuptools >= 0.8 for dist-info support.
   pip's wheel support requires setuptools >= 0.8 for dist-info support.
   

   Add --no-use-wheel to above cmd:

   pip install setuptools --no-use-wheel --upgrade
   

Now, you can install libraries for python, just by:

pip install library_name

For example:

pip install requests

Note that to install some library may they need to compile, so you need to have compiler.

On windows there is a site for Unofficial Windows Binaries for Python Extension Packages that have huge python packages and complied python packages for windows.

For example to install pip using this site, just download and install setuptools and pip installer from that.

For a list of recent table changes use this:

SELECT UPDATE_TIME, TABLE_SCHEMA, TABLE_NAME
FROM information_schema.tables
ORDER BY UPDATE_TIME DESC, TABLE_SCHEMA, TABLE_NAME

You can also use DateTime.Now.ToString("yyyy-MM-dd") for the date, and DateTime.Now.ToString("hh:mm:ss") for the time.

I suggest

l = re.compile("(?<!^)\s+(?=[A-Z])(?!.\s)").split(s)

Check this demo.

I don't recommend storing passwords in a script, but this is a way to what you indicate:

use 5.010;
my %user_table = ( tom => '123!', frank => '321!' );

say ( $user_table{ $name } eq $password ? 'You have gained access.'
    :                                     'Access denied!'
    );

Any time you want to enforce an association like this, it's a good idea to think of a table, and the most common form of table in Perl is the hash.

It can be done.

From the designer: Select your DataGridView Open the Properties Navigate to ColumnHeaderDefaultCellStype Hit the button to edit the style.

You can also do it programmatically:

dataGridView1.ColumnHeadersDefaultCellStyle.BackColor = Color.Purple;

Hope that helps!

According to the doc, the default implementation of hashCode will return some integer that differ for every object

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation
technique is not required by the JavaTM programming language.)

However some time you want the hash code to be the same for different object that have the same meaning. For example

Student s1 = new Student("John", 18);
Student s2 = new Student("John", 18);
s1.hashCode() != s2.hashCode(); // With the default implementation of hashCode

This kind of problem will be occur if you use a hash data structure in the collection framework such as HashTable, HashSet. Especially with collection such as HashSet you will end up having duplicate element and violate the Set contract.

This error usually occurs if you have not included the xmlns:mm properly, it occurs usually in the first line of code.

for me it was..

xmlns:mm="http://millennialmedia.com/android/schema"

that i missed in first line of the code

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:mm="http://millennialmedia.com/android/schema"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:layout_marginTop="50dp"
android:layout_marginBottom="50dp"
android:background="@android:color/transparent" >

From the Google Font Directory examples:

@font-face {
  font-family: 'Tangerine';
  font-style: normal;
  font-weight: normal;
  src: local('Tangerine'), url('http://example.com/tangerine.ttf') format('truetype');
}
body {
  font-family: 'Tangerine', serif;
  font-size: 48px;
}

This works cross browser with .ttf, I believe it may work with .otf. (Wikipedia says .otf is mostly backwards compatible with .ttf) If not, you can convert the .otf to .ttf

When passing a struct to another function, it would usually be better to do as Donnell suggested above and pass it by reference instead.

A very good reason for this is that it makes things easier if you want to make changes that will be reflected when you return to the function that created the instance of it.

Here is an example of the simplest way to do this:

#include <stdio.h>

typedef struct student {
    int age;
} student;

void addStudent(student *s) {
    /* Here we can use the arrow operator (->) to dereference 
       the pointer and access any of it's members: */
    s->age = 10;
}

int main(void) {

    student aStudent = {0};     /* create an instance of the student struct */
    addStudent(&aStudent);      /* pass a pointer to the instance */

    printf("%d", aStudent.age);

    return 0;
}

In this example, the argument for the addStudent() function is a pointer to an instance of a student struct - student *s. In main(), we create an instance of the student struct and then pass a reference to it to our addStudent() function using the reference operator (&).

In the addStudent() function we can make use of the arrow operator (->) to dereference the pointer, and access any of it's members (functionally equivalent to: (*s).age).

Any changes that we make in the addStudent() function will be reflected when we return to main(), because the pointer gave us a reference to where in the memory the instance of the student struct is being stored. This is illustrated by the printf(), which will output "10" in this example.

Had you not passed a reference, you would actually be working with a copy of the struct you passed in to the function, meaning that any changes would not be reflected when you return to main - unless you implemented a way of passing the new version of the struct back to main or something along those lines!

Although pointers may seem off-putting at first, once you get your head around how they work and why they are so handy they become second nature, and you wonder how you ever coped without them!

I was also facing the same problem and I spent more than a week to fix it. Restarting my machine seemed to have fixed it, but only temporarily.

There was a solution to increase the maximum number of ephemeral ports by editing the registry file. That seemed to have fixed the problem but that also, only temporarily.

For sometime, I kept thinking if I was trying to access a driver which is no longer available, so I have tried to call:

driver.quit()

And then recreate the browser instance, which only gave me: SessionNotFoundException.

I now realized that I had used BOTH System.setProperty as well as ffCapability.setCapability to set the path of the binary.

I then tried with only System.setProperty => No luck there.

Only ffCapability.setCapability => Voila!!! So far it has been working fine. Hopefully it will work great when I try to re-run my scripts tomorrow and the day after and the day after... :)

Bottomline: Use only this

ffCapability.setCapability("binary", "C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe"); //for windows`

Hope it helps!

A simple solution (assuming you're using a decent IDE) is to just type 'int' everywhere and then get it to set the type for you.

I actually just added a class called 'var' so I don't have to type something different.

The code is still too verbose, but at least you don't have to type it!

If you're in Rails, .blank? should be the method you are looking for:

a = nil
b = []
c = ""

a.blank? #=> true
b.blank? #=> true
c.blank? #=> true

d = "1"
e = ["1"]

d.blank? #=> false
e.blank? #=> false

So the answer would be:

variable = id if variable.blank?

#!/bin/sh or #!/bin/bash has to be first line of the script because if you don't use it on the first line then the system will treat all the commands in that script as different commands. If the first line is #!/bin/sh then it will consider all commands as a one script and it will show the that this file is running in ps command and not the commands inside the file.

./echo.sh

ps -ef |grep echo
trainee   3036  2717  0 16:24 pts/0    00:00:00 /bin/sh ./echo.sh
root      3042  2912  0 16:24 pts/1    00:00:00 grep --color=auto echo

To get fancier tables like

---------------------------------------------------

Try this, works!

Excel.Worksheet sheet = xlWorkSheet;
Excel.Series series1 = seriesCollection.NewSeries();
Excel.Range rng = (Excel.Range)xlWorkSheet.Range[xlWorkSheet.Cells[3, 13], xlWorkSheet.Cells[pp, 13]].Cells;
series1.Values = rng;

You should remove the & (ampersand) symbol, so that line 4 will look like this:

$conn = ADONewConnection($config['db_type']);

This is because ADONewConnection already returns an object by reference. As per documentation, assigning the result of a reference to object by reference results in an E_DEPRECATED message as of PHP 5.3.0

Well, if you have a ResultSet of type ResultSet.TYPE_FORWARD_ONLY you want to keep it that way (and not to switch to a ResultSet.TYPE_SCROLL_INSENSITIVE or ResultSet.TYPE_SCROLL_INSENSITIVE in order to be able to use .last()).

I suggest a very nice and efficient hack, where you add a first bogus/phony row at the top containing the number of rows.

Example

Let's say your query is the following

select MYBOOL,MYINT,MYCHAR,MYSMALLINT,MYVARCHAR
from MYTABLE
where ...blahblah...

and your output looks like

true    65537 "Hey" -32768 "The quick brown fox"
false  123456 "Sup"    300 "The lazy dog"
false -123123 "Yo"       0 "Go ahead and jump"
false       3 "EVH"    456 "Might as well jump"
...
[1000 total rows]

Simply refactor your code to something like this:

Statement s=myConnection.createStatement(ResultSet.TYPE_FORWARD_ONLY,
                                         ResultSet.CONCUR_READ_ONLY);
String from_where="FROM myTable WHERE ...blahblah... ";
//h4x
ResultSet rs=s.executeQuery("select count(*)as RECORDCOUNT,"
                           +       "cast(null as boolean)as MYBOOL,"
                           +       "cast(null as int)as MYINT,"
                           +       "cast(null as char(1))as MYCHAR,"
                           +       "cast(null as smallint)as MYSMALLINT,"
                           +       "cast(null as varchar(1))as MYVARCHAR "
                           +from_where
                           +"UNION ALL "//the "ALL" part prevents internal re-sorting to prevent duplicates (and we do not want that)
                           +"select cast(null as int)as RECORDCOUNT,"
                           +       "MYBOOL,MYINT,MYCHAR,MYSMALLINT,MYVARCHAR "
                           +from_where);

Your query output will now be something like

1000 null     null null    null null
null true    65537 "Hey" -32768 "The quick brown fox"
null false  123456 "Sup"    300 "The lazy dog"
null false -123123 "Yo"       0 "Go ahead and jump"
null false       3 "EVH"    456 "Might as well jump"
...
[1001 total rows]

So you just have to

if(rs.next())
    System.out.println("Recordcount: "+rs.getInt("RECORDCOUNT"));//hack: first record contains the record count
while(rs.next())
    //do your stuff

just you pass this things in your select query. using CASE

CASE WHEN  gender=0 then 'Female' WHEN  gender=1 then 'Male' END as Genderdisp

I managed to make it work with the following code:

event.preventDefault();
timeout(function () {
    $inputToFocus.focus();
}, 500);

I'm using AngularJS so I have created a directive which solved my problem:

Directive:

angular.module('directivesModule').directive('focusOnClear', [
    '$timeout',
    function (timeout) {
        return {
            restrict: 'A',
            link: function (scope, element, attrs) {
                var id = attrs.focusOnClear;
                var $inputSearchElement = $(element).parent().find('#' + id);
                element.on('click', function (event) {
                    event.preventDefault();
                    timeout(function () {
                        $inputSearchElement.focus();
                    }, 500);
                });
            }
        };
    }
]);

How to use the directive:

<div>
    <input type="search" id="search">
    <i class="icon-clear" ng-click="clearSearchTerm()" focus-on-clear="search"></i>
</div>

It looks like you are using jQuery, so I don't know if the directive is any help.

For MAC 10.8+:

sudo ln -s /Applications/Sublime\ Text.app/Contents/SharedSupport/bin/subl /usr/local/bin/subl

worked.

I wrote an npm module to solve this problem. It's available here:

object-types: a module for finding what literal types underly objects

Install

  npm install --save object-types

Usage

const objectTypes = require('object-types');

objectTypes({});
//=> 'object'

objectTypes([]);
//=> 'array'

objectTypes(new Object(true));
//=> 'boolean'

Take a look, it should solve your exact problem. Let me know if you have any questions! https://github.com/dawsonbotsford/object-types

I think your code is trying to "divide by zero" or "divide by NaN". If you are aware of that and don't want it to bother you, then you can try:

import numpy as np
np.seterr(divide='ignore', invalid='ignore')

For more details see:

• http://docs.scipy.org/doc/numpy/reference/generated/numpy.seterr.html

You can get a view for a particular position on a recyclerview using the following

int position = 2;
RecyclerView.ViewHolder viewHolder = recyclerview.findViewHolderForItemId(position);
View view = viewHolder.itemView;
ImageView imageView = (ImageView)view.findViewById(R.id.imageView);

I don't know of any way to do this with grep, but it is possible to use awk to achieve the same result:

awk '/blah/ {getline;print}' < logfile

?php

/* Database config */

$db_host        = 'localhost';
$db_user        = '~';
$db_pass        = '~';
$db_database    = 'banners'; 

/* End config */


$mysqli = new mysqli($db_host, $db_user, $db_pass, $db_database);
/* check connection */
if (mysqli_connect_errno()) {
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}

?>

In Ionic 2 there's a easier way to do that. See the Ionic Docs.

It is more or less like the following:

<ion-grid>
  <ion-row>
    <ion-col>
      1 of 3
    </ion-col>
    <ion-col>
      2 of 3
    </ion-col>
    <ion-col>
      3 of 3
    </ion-col>
  </ion-row>
</ion-grid>

I'm positive it would require SMTP authentication credentials as well.

HTTP_HOST is the target host sent by the client. It can be manipulated freely by the user. It's no problem to send a request to your site asking for a HTTP_HOST value of www.stackoverflow.com.

SERVER_NAME comes from the server's VirtualHost definition and is therefore considered more reliable. It can, however, also be manipulated from outside under certain conditions related to how your web server is set up: See this This SO question that deals with the security aspects of both variations.

You shouldn't rely on either to be safe. That said, what to use really depends on what you want to do. If you want to determine which domain your script is running on, you can safely use HTTP_HOST as long as invalid values coming from a malicious user can't break anything.

if you are trying to add a general note to the overall object (query or table etc..)

Access 2016 go to navigation pane, highlight object, right click, select object / table properties, add a note in the description window i.e. inventory "table last last updated 05/31/17"

There are a lot of ways to accomplish this, and this is but one of them.

$("table").find("tbody td").eq(0).children().first()

I had this problem. I think that it was caused by the socket getting opened and no data arriving within a short time after the open. I was reading from a serial to ethernet box called a Devicemaster. I changed the Devicemaster port setting from "connect always" to "connect on data" and the problem disappeared. I have great respect for Hans Passant but I do not agree that this is an error code that you can easily solve by scrutinizing code.

The exclude option needs to include the = sign and " are not required.

--exclude=/home/user/public_html/tmp

Thought I'd write exactly what I did (Windows 10, 64-bit):

From the download page https://curl.haxx.se/download.html choose the download wizard https://curl.haxx.se/dlwiz/

Choose curl executable.

Choose Win64.

Choose generic.

Choose any.

Choose x86_64.

Choose the first recommended option. For me this was:

curl version: 7.53.1 - SSL enabled SSH enabled. Provided by: Viktor Szakáts. This package is type curl executable You will get a pre-built 'curl' binary from this link (or in some cases, by using the information that is provided at the page this link takes you). You may or may not get 'libcurl' installed as a shared library/DLL. The file is packaged using 7zip. 7zip is a file archiving format.

Click download.

You should have the file curl-7.53.1-win64-mingw.7z in your downloads folder.

Install 7-Zip if you don't have it.

Right-click, 7-Zip, Extract Here. Copy and paste the extracted file somewhere like Z:\Tools\

If you look in the bin folder you'll see curl.exe. If you double-click it a window will quickly flash up and vanish. To run it you need to use the Command Prompt. Navigate to the bin folder and type curl followed by your parameters to make a request. You must use double-quotes. Single quotes won't work with curl on Windows.

Now you'll want to add curl to a user's Path variable so you don't have to navigate to the right folder to run the program. Go to This PC, Computer, System Properties, Advanced system settings, authenticate as an administrator (you're not running as admin, right? Right?) Environment Variables, System variables, look at the list and select Path, then Edit, then New, then, e.g.

Z:\Tools\curl-7.53.1-win64-mingw\bin

You can add a trailing backslash if you like, I don't think it matters. Click move up until it's at the top of the list, then you can see it easily from the previous screen. Click OK, OK, OK, then crack open a Command Prompt and you can run curl by typing curl from any folder, as any user. Don't forget your double-quotes.

This is the answer I wish I'd had.

Through Configuration, you can do this:

Model1
{
    int fk_one,
    int fk_two
}

Model2
{
    int pk_one,
    int pk_two,
}

then in the context config

public class MyContext : DbContext
{
    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        modelBuilder.Entity<Model1>()
            .HasRequired(e => e.Model2)
            .WithMany(e => e.Model1s)
            .HasForeignKey(e => new { e.fk_one, e.fk_two })
            .WillCascadeOnDelete(false);
    }
}
