Can do some thing like a tuple in dynamic language (Python)

public class Tuple {
private Object[] multiReturns;

private Tuple(Object... multiReturns) {
    this.multiReturns = multiReturns;
}

public static Tuple _t(Object... multiReturns){
    return new Tuple(multiReturns);
}

public <T> T at(int index, Class<T> someClass) {
    return someClass.cast(multiReturns[index]);
}
}

and use like this

public Tuple returnMultiValues(){
   return Tuple._t(new ArrayList(),new HashMap())
}


Tuple t = returnMultiValues();
ArrayList list = t.at(0,ArrayList.class);

The best way to handle the LazyInitializationException is to use the JOIN FETCH directive:

Query query = session.createQuery("""
    select m
    from Model m
    join fetch m.modelType
    where modelGroup.id = :modelGroupId
    """
);

Anyway, DO NOT use the following Anti-Patterns as suggested by some of the answers:

• Open Session in View
• hibernate.enable_lazy_load_no_trans

Sometimes, a DTO projection is a better choice than fetching entities, and this way, you won't get any LazyInitializationException.

Another idea is using letter-spacing

li, a { display: inline-block; }_x000D_
a {_x000D_
  font-size: 14px;_x000D_
  padding-left: 10px;_x000D_
  padding-right: 10px;_x000D_
  letter-spacing: 0.235px_x000D_
}_x000D_
_x000D_
a:hover, a:focus {_x000D_
  font-weight: bold;_x000D_
  letter-spacing: 0_x000D_
}

<ul>_x000D_
  <li><a href="#">item 1</a></li>_x000D_
  <li><a href="#">item 2</a></li>_x000D_
  <li><a href="#">item 3</a></li>_x000D_
</ul>

Based on solution You've already found How to apply CSS to iframe?:

var cssLink = document.createElement("link") 
cssLink.href = "file://path/to/style.css"; 
cssLink .rel = "stylesheet"; 
cssLink .type = "text/css"; 
frames['iframe'].document.body.appendChild(cssLink);

or more jqueryish (from Append a stylesheet to an iframe with jQuery):

var $head = $("iframe").contents().find("head");                
$head.append($("<link/>", 
    { rel: "stylesheet", href: "file://path/to/style.css", type: "text/css" }));

It's one of the assignment operators. It takes the value of x, adds 0.1 to it, and then stores the result of (x + 0.1) back into x.

So:

double x = 1.3;
x += 0.1;    // sets 'x' to 1.4

It's functionally identical to, but shorter than:

double x = 1.3;
x = x + 0.1;

NOTE: When doing floating-point math, things don't always work the way you think they will.

According to the documentation:

import React, { useState, useEffect } from 'react'
// Similar to componentDidMount and componentDidUpdate:

useEffect(() => {


});

see React documentation

It depends on what you want to do.

Case # 1: Save the model to use it yourself for inference: You save the model, you restore it, and then you change the model to evaluation mode. This is done because you usually have BatchNorm and Dropout layers that by default are in train mode on construction:

torch.save(model.state_dict(), filepath)

#Later to restore:
model.load_state_dict(torch.load(filepath))
model.eval()

Case # 2: Save model to resume training later: If you need to keep training the model that you are about to save, you need to save more than just the model. You also need to save the state of the optimizer, epochs, score, etc. You would do it like this:

state = {
    'epoch': epoch,
    'state_dict': model.state_dict(),
    'optimizer': optimizer.state_dict(),
    ...
}
torch.save(state, filepath)

To resume training you would do things like: state = torch.load(filepath), and then, to restore the state of each individual object, something like this:

model.load_state_dict(state['state_dict'])
optimizer.load_state_dict(state['optimizer'])

Since you are resuming training, DO NOT call model.eval() once you restore the states when loading.

Case # 3: Model to be used by someone else with no access to your code: In Tensorflow you can create a .pb file that defines both the architecture and the weights of the model. This is very handy, specially when using Tensorflow serve. The equivalent way to do this in Pytorch would be:

torch.save(model, filepath)

# Then later:
model = torch.load(filepath)

This way is still not bullet proof and since pytorch is still undergoing a lot of changes, I wouldn't recommend it.

The best way is to use mpack!

mpack -s "Subject" -d "./body.txt" "././image.png" mailadress

mpack - subject - body - attachment - mailadress

It looks like you're running this on Windows (given your H://log.txt file path).

Try using \r\n instead of just \n.

Honestly, \n is fine; you're probably viewing the log file in notepad or something else that doesn't render non-Windows newlines. Try opening it in a different viewer/editor (e.g. Wordpad).

Take a loot at the Wikipedia article on random numbers as it talks about using sampling techniques. You can find the equation for your normal distribution by plugging into this one

(equation via Wikipedia)

As for the second issue, go into Options under the circle Office icon, go to formulas, and change calculations to "Manual". That will maintain your sheet and not recalculate the formulas each time.

Python is upset because you are attempting to assign a value to something that can't be assigned a value.

((t[1])/length) * t[1] += string

When you use an assignment operator, you assign the value of what is on the right to the variable or element on the left. In your case, there is no variable or element on the left, but instead an interpreted value: you are trying to assign a value to something that isn't a "container".

Based on what you've written, you're just misunderstanding how this operator works. Just switch your operands, like so.

string += str(((t[1])/length) * t[1])

Note that I've wrapped the assigned value in str in order to convert it into a str so that it is compatible with the string variable it is being assigned to. (Numbers and strings can't be added together.)

If someone is having problem with finding CURL in the list in setup.exe (Cygwin package manager) then trying downloading 64bit version of this setup. Worked for me.

There is no documented LEFT() function in Oracle. Find the full set here.

Probably what you have is a user-defined function. You can check that easily enough by querying the data dictionary:

select * from all_objects
where object_name = 'LEFT'

But there is the question of why the stored procedure works and the query doesn't. One possible solution is that the stored procedure is owned by another schema, which also owns the LEFT() function. They have granted rights on the procedure but not its dependencies. This works because stored procedures run with DEFINER privileges by default, so you run the stored procedure as if you were its owner.

If this is so then the data dictionary query I listed above won't help you: it will only return rows for objects you have rights on. In which case you will need to run the query as the stored procedure's owner or connect as a user with the rights to query DBA_OBJECTS instead.

This Works for me. I have to use specially date format like this 'YY-MM-dd hh:mm' or 'YYYY-MM-dd hh:mm'

$('#datetimepicker1').datetimepicker({
            format: 'YYYY-MM-dd hh:mm',
            defaultDate: new Date()
        });

You can simply center the image and text in the parent tag by setting

div {
     text-align: center;
}

vertical center the img and span

img {
     vertical-align:middle;
}
span {
     vertical-align:middle;
}

You can just add second set below, and one thing to mention is that h4 has block display attribute, so you might want to set

h4 {
    display: inline-block
}

to set the h4 "inline".

The full example is shown here.

<div id="photo" style="text-align: center">_x000D_
  <img style="vertical-align:middle" src="https://via.placeholder.com/22x22" alt="">_x000D_
  <span style="vertical-align:middle">Take a photo</span>_x000D_
</div>

Using the AWS 'user data' and 'meta data' APIs its possible to write a script which wraps puppet to start a puppet run with a custom cert name.

First start an aws instance with custom user data: 'role:webserver'

#!/bin/bash

# Find the name from the user data passed in on instance creation
USER=$(curl -s "http://169.254.169.254/latest/user-data")
IFS=':' read -ra UDATA <<< "$USER"

# Find the instance ID from the meta data api
ID=$(curl -s "http://169.254.169.254/latest/meta-data/instance-id")
CERTNAME=${UDATA[1]}.$ID.aws

echo "Running Puppet for certname: " $CERTNAME
puppet agent -t --certname=$CERTNAME 

This calls puppet with a certname like 'webserver.i-hfg453.aws' you can then create a node manifest called 'webserver' and puppets 'fuzzy node matching' will mean it is used to provision all webservers.

This example assumes you build on a base image with puppet installed etc.

Benefits:

1) You don't have to pass round your credentials

2) You can be as granular as you like with the role configs.

You've mentioned that they each have their own machines, but if they need to log onto a co-workers machine, and then use the file, saving it through "C:\Users\Public\Desktop\" will make it available to different usernames.

Public Sub SaveToDesktop()
    ThisWorkbook.SaveAs Filename:="C:\Users\Public\Desktop\" & ThisWorkbook.Name & "_copy", _ 
    FileFormat:=xlOpenXMLWorkbookMacroEnabled
End Sub

I'm not sure whether this would be a requirement, but may help!

In case you want to initialize a fixed array of pre-initialized equal (non-null or other than default) elements, use this:

var array = Enumerable.Repeat(string.Empty, 37).ToArray();

Where can I get pre-built JavaFX libraries for OpenJDK (Windows)

On Linux its not really a problem, but on Windows its not that easy, especially if you want to distribute the JRE.

You can actually use OpenJFX with OpenJDK 8 on windows, you just have to assemble it yourself:

Download the OpenJDK from here: https://github.com/AdoptOpenJDK/openjdk8-releases/releases/tag/jdk8u172-b11

Download OpenJFX from here: https://github.com/SkyLandTW/OpenJFX-binary-windows/releases/tag/v8u172-b11

copy all the files from the OpenFX zip on top of the JDK, voila, you have an OpenJDK with JavaFX.

Update:

Fortunately from Azul there is now a OpenJDK+OpenJFX build which can be downloaded at their community page: https://www.azul.com/downloads/zulu-community/?&version=java-8-lts&os=windows&package=jdk-fx

Before you start reinventing the wheel with one of these answers, check out the Material Card widget. It also allows you to define a global style via the app theme directly:

you can do these line on your mysql query browser or something

SET old_passwords = 0;
UPDATE mysql.user SET Password = PASSWORD('testpass') WHERE User = 'testuser' limit 1;
SELECT LENGTH(Password) FROM mysql.user WHERE User = 'testuser';
FLUSH PRIVILEGES;

note:your username and password

after that it should able to work. I just solved mine too

I use to use the Do, Loop a lot but I have started using a Sub or a Function that I could exit out of instead. It just seemed cleaner to me. If any variables you need are not global you will need to pass them to the Sub also.

For i=1 to N
 DoWork i
Next

Sub DoWork(i)
    [Code]
    If Condition1 Then
      Exit Sub
    End If

    [MoreCode]
    If Condition2 Then
      Exit Sub
    End If

[UPDATE]

The original question, and the answer below applied specifically to the IE11 preview releases.

The final release version of IE11 does in fact provide the ability to switch browser modes from the Emulation tab in the dev tools:

Having said that, the advice I've given here (and elsewhere) to avoid using compatibility modes for testing is still valid: If you want to test your site for compatibility with older IE versions, you should always do your testing in a real copy of those IE version.

However, this does mean that the registry hack described in @EugeneXa's answer to bring back the old dev tools is no longer necessary, since the new dev tools do now have the feature he was missing.

The IE devs have deliberately deprecated the ability to switch browser mode.

There are not many reasons why people would be switching modes in the dev tools, but one of the main reasons is because they want to test their site in old IE versions. Unfortunately, the various compatibility modes that IE supplies have never really been fully compatible with old versions of IE, and testing using compat mode is simply not a good enough substitute for testing in real copies of IE8, IE9, etc.

The IE devs have recognised this and are deliberately making it harder for devs to make this mistake.

The best practice is to use real copies of each IE version to test your site instead.

The various compatiblity modes are still available inside IE11, but can only be accessed if a site explicitly states that it wants to run in compat mode. You would do this by including an X-UA-Compatible header on your page.

And the Document Mode drop-box is still available, but will only ever offer the options of "Edge" (that is, the best mode available to the current IE version, so IE11 mode in IE11) or the mode that the page is running in.

So if you go to a page that is loaded in compat mode, you will have the option to switch between the specific compat mode that the page was loaded in or IE11 "Edge" mode.

And if you go to a page that loads in IE11 mode, then you will only be offered the 'edge' mode and nothing else.

This means that it does still allow you to test how a compat mode page reacts to being updated to work in Edge mode, which is about the only really legitimate use-case for the document mode drop-box anyway.

The IE11 Document Mode drop box has an i icon next to it which takes you to the modern.ie website. The point of this is to encourage you to download the VMs that MS are supplying for us to test our sites using real copies of each version of IE. This will give you a much more accurate testing experience, and is strongly enouraged as a much better practice than testing by switching the mode in dev tools.

Hope that explains things a bit for you.

you can also use

.detail_container h1:nth-of-type(1)

By changing the number 1 by any other number you can select any other h1 item.

Newer versions of OpenSSL say BEGIN PRIVATE KEY because they contain the private key + an OID that identifies the key type (this is known as PKCS8 format). To get the old style key (known as either PKCS1 or traditional OpenSSL format) you can do this:

openssl rsa -in server.key -out server_new.key

Alternately, if you have a PKCS1 key and want PKCS8:

openssl pkcs8 -topk8 -nocrypt -in privkey.pem

Optionals and default parameters are two different things.

An Optional is a variable that can be nil, that's it.

Default parameters use a default value when you omit that parameter, this default value is specified like this: func test(param: Int = 0)

If you specify a parameter that is an optional, you have to provide it, even if the value you want to pass is nil. If your function looks like this func test(param: Int?), you can't call it like this test(). Even though the parameter is optional, it doesn't have a default value.

You can also combine the two and have a parameter that takes an optional where nil is the default value, like this: func test(param: Int? = nil).

Robocopy can be downloaded here for systems where it is not installed already. (I.e. Windows Server 2003.)

http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=17657 (no reboot required for installation)

Remember to set your path to the robocopy exe. You do this by right clicking "my computer"> properties>advanced>"Environment Variables", then find the path system variable and add this to the end: ";C:\Program Files\Windows Resource Kits\Tools" or wherever you installed it. Make sure to leave the path variable strings that are already there and just append the addtional path.

once the path is set, you can run the command that belisarius suggests. It works great.

Have you tried to avoid the +=? instead use var = var + ... it worked for me.

#include <iostream.h> // for string

string myName = "";
int _age = 30;
myName = myName + "Vincent" + "Thorpe" + 30 + " " + 2019;

The XP Support Tools (which can be installed from your XP CD) come with a program called setx.exe:

C:\Program Files\Support Tools>setx /?

SETX: This program is used to set values in the environment
of the machine or currently logged on user using one of three modes.

1) Command Line Mode: setx variable value [-m]
   Optional Switches:
    -m  Set value in the Machine environment. Default is User.

...
For more information and example use: SETX -i

I think Windows 7 actually comes with setx as part of a standard install.

ALTER TABLE is standard SQL. But it's not completely implemented in many database systems.

I'd download PuTTY and run a telnet session on port 80 to the webserver you want

HEAD /resource HTTP/1.1
Host: www.example.com

You could alternatively download Perl and try LWP's HEAD command. Or write your own script.

Other solutions didn't work in one of my projects and I've ending up checking overflow css property

function haveScrollbar() {
    var style = window.getComputedStyle(document.body);
    return style["overflow-y"] != "hidden";
}

but it will only work if scrollbar appear disappear by changing the prop it will not work if the content is equal or smaller than the window.

If the variant is empty then an error will be thrown. The bullet-proof code is the following:

Public Function GetLength(a As Variant) As Integer
   If IsEmpty(a) Then
      GetLength = 0
   Else
      GetLength = UBound(a) - LBound(a) + 1
   End If
End Function

Heres a another take on this problem, using recursion and without using mutable variables. Also, im not using setInterval so theres no cleanup that has to be done.

Having this HTML

<section id="testimonials">
    <h2>My testimonial spinner</h2>
    <div class="testimonial">
      <p>First content</p>
    </div>
    <div class="testimonial">
      <p>Second content</p>
    </div>
    <div class="testimonial">
       <p>Third content</p>
    </div>
</section>

Using ES2016

Here you call the function recursively and update the arguments.

  const testimonials = $('#testimonials')
      .children()
      .filter('div.testimonial');

  const showTestimonial = index => {

    testimonials.hide();
    $(testimonials[index]).fadeIn();

    return index === testimonials.length
      ? showTestimonial(0)
      : setTimeout(() => { showTestimonial(index + 1); }, 10000);
   }

showTestimonial(0); // id of the first element you want to show.

Use a parameter array with the params modifier:

public static int AddUp(params int[] values)
{
    int sum = 0;
    foreach (int value in values)
    {
        sum += value;
    }
    return sum;
}

If you want to make sure there's at least one value (rather than a possibly empty array) then specify that separately:

public static int AddUp(int firstValue, params int[] values)

(Set sum to firstValue to start with in the implementation.)

Note that you should also check the array reference for nullity in the normal way. Within the method, the parameter is a perfectly ordinary array. The parameter array modifier only makes a difference when you call the method. Basically the compiler turns:

int x = AddUp(4, 5, 6);

into something like:

int[] tmp = new int[] { 4, 5, 6 };
int x = AddUp(tmp);

You can call it with a perfectly normal array though - so the latter syntax is valid in source code as well.

MaxLengthAttribute means Max. length of array or string data allowed

StringLengthAttribute means Min. and max. length of characters that are allowed in a data field

In Ubuntu 16.04 default PHP version is 7.0, if you want to use different version then you need to install PHP package according to PHP version:

• PHP 7.4: sudo apt-get install php7.4-curl
• PHP 7.3: sudo apt-get install php7.3-curl
• PHP 7.2: sudo apt-get install php7.2-curl
• PHP 7.1: sudo apt-get install php7.1-curl
• PHP 7.0: sudo apt-get install php7.0-curl
• PHP 5.6: sudo apt-get install php5.6-curl
• PHP 5.5: sudo apt-get install php5.5-curl

Based on link you've provided, right answer should be

Math.floor(Math.random()*899999+100000);

Math.random() returns float between 0 and 1, so minimum number will be 100000, max - 999999. Exactly 6 digits, as you wanted :)

For some reason, you're re-instantiating the form after you check is_valid(). Forms only get a cleaned_data attribute when is_valid() has been called, and you haven't called it on this new, second instance.

Just get rid of the second form = SearchForm(request.POST) and all should be well.

Cast the datetime to a date, then GROUP BY using this syntax:

SELECT SUM(foo), DATE(mydate) FROM a_table GROUP BY DATE(a_table.mydate);

Or you can GROUP BY the alias as @orlandu63 suggested:

SELECT SUM(foo), DATE(mydate) DateOnly FROM a_table GROUP BY DateOnly;

Though I don't think it'll make any difference to performance, it is a little clearer.

You could always listen to the window resize event. If, on that event, the window went from being taller than it is wide to wider than it is tall (or vice versa), you can be pretty sure the phone orientation was just changed.

You may have moved on by now, but... as far as I know there's no way to delete a history entry (or state).

One option I've been looking into is to handle the history yourself in JavaScript and use the window.history object as a carrier of sorts.

Basically, when the page first loads you create your custom history object (we'll go with an array here, but use whatever makes sense for your situation), then do your initial pushState. I would pass your custom history object as the state object, as it may come in handy if you also need to handle users navigating away from your app and coming back later.

var myHistory = [];

function pageLoad() {
    window.history.pushState(myHistory, "<name>", "<url>");

    //Load page data.
}

Now when you navigate, you add to your own history object (or don't - the history is now in your hands!) and use replaceState to keep the browser out of the loop.

function nav_to_details() {
    myHistory.push("page_im_on_now");
    window.history.replaceState(myHistory, "<name>", "<url>");

    //Load page data.
}

When the user navigates backwards, they'll be hitting your "base" state (your state object will be null) and you can handle the navigation according to your custom history object. Afterward, you do another pushState.

function on_popState() {
    // Note that some browsers fire popState on initial load,
    // so you should check your state object and handle things accordingly.
    // (I did not do that in these examples!)

    if (myHistory.length > 0) {
        var pg = myHistory.pop();
        window.history.pushState(myHistory, "<name>", "<url>");

        //Load page data for "pg".
    } else {
        //No "history" - let them exit or keep them in the app.
    }
}

The user will never be able to navigate forward using their browser buttons because they are always on the newest page.

From the browser's perspective, every time they go "back", they've immediately pushed forward again.

From the user's perspective, they're able to navigate backwards through the pages but not forward (basically simulating the smartphone "page stack" model).

From the developer's perspective, you now have a high level of control over how the user navigates through your application, while still allowing them to use the familiar navigation buttons on their browser. You can add/remove items from anywhere in the history chain as you please. If you use objects in your history array, you can track extra information about the pages as well (like field contents and whatnot).

If you need to handle user-initiated navigation (like the user changing the URL in a hash-based navigation scheme), then you might use a slightly different approach like...

var myHistory = [];

function pageLoad() {
    // When the user first hits your page...
    // Check the state to see what's going on.

    if (window.history.state === null) {
        // If the state is null, this is a NEW navigation,
        //    the user has navigated to your page directly (not using back/forward).

        // First we establish a "back" page to catch backward navigation.
        window.history.replaceState(
            { isBackPage: true },
            "<back>",
            "<back>"
        );

        // Then push an "app" page on top of that - this is where the user will sit.
        // (As browsers vary, it might be safer to put this in a short setTimeout).
        window.history.pushState(
            { isBackPage: false },
            "<name>",
            "<url>"
        );

        // We also need to start our history tracking.
        myHistory.push("<whatever>");

        return;
    }

    // If the state is NOT null, then the user is returning to our app via history navigation.

    // (Load up the page based on the last entry of myHistory here)

    if (window.history.state.isBackPage) {
        // If the user came into our app via the back page,
        //     you can either push them forward one more step or just use pushState as above.

        window.history.go(1);
        // or window.history.pushState({ isBackPage: false }, "<name>", "<url>");
    }

    setTimeout(function() {
        // Add our popstate event listener - doing it here should remove
        //     the issue of dealing with the browser firing it on initial page load.
        window.addEventListener("popstate", on_popstate);
    }, 100);
}

function on_popstate(e) {
    if (e.state === null) {
        // If there's no state at all, then the user must have navigated to a new hash.

        // <Look at what they've done, maybe by reading the hash from the URL>
        // <Change/load the new page and push it onto the myHistory stack>
        // <Alternatively, ignore their navigation attempt by NOT loading anything new or adding to myHistory>

        // Undo what they've done (as far as navigation) by kicking them backwards to the "app" page
        window.history.go(-1);

        // Optionally, you can throw another replaceState in here, e.g. if you want to change the visible URL.

                // And push them to our "app" page again
                window.history.pushState(
                    { isBackPage: false },
                    "<name>",
                    "<url>"
                );
            } else {
                // No more history - let them exit or keep them in the app.
            }
        }

        // Implied 'else' here - if there is state and it's NOT the 'back' page
        //     then we can ignore it since we're already on the page we want.
        //     (This is the case when we push the user back with window.history.go(-1) above)
    }

object-fit, behaves like background-size, solving the issue of scaling images up and down to fit.

The object-fit CSS property specifies how the contents of a replaced element should be fitted to the box established by its used height and width.

https://developer.mozilla.org/en-US/docs/Web/CSS/object-fit

.cover img {
    width: 100%;
    height: 100%;
    object-fit: cover;
    overflow: hidden;
}

Browser Support

There's no IE support, and support in Edge begins at v16, only for img element: https://caniuse.com/#search=object-fit

The bfred-it/object-fit-images polyfill works very well for me in IE11, tested on Browserstack: demo.

Alternative without polyfill using an image in SVG

For Edge pre v16, and ie9, ie10, ie11:

You can crop and scale any image using CSS object-fit and object-position. However, these properties are only supported in the latest version of MS Edge as well as all other modern browsers.

If you need to crop and scale an image in Internet Explorer and provide support back to IE9, you can do that by wrapping the image in an <svg>, and using the viewBox and preserveAspectRatio attributes to do what object-fit and object-position do.

to_date() returns a date at 00:00:00, so you need to "remove" the minutes from the date you are comparing to:

select * 
from table
where trunc(es_date) = TO_DATE('27-APR-12','dd-MON-yy')

You probably want to create an index on trunc(es_date) if that is something you are doing on a regular basis.

The literal '27-APR-12' can fail very easily if the default date format is changed to anything different. So make sure you you always use to_date() with a proper format mask (or an ANSI literal: date '2012-04-27')

Although you did right in using to_date() and not relying on implict data type conversion, your usage of to_date() still has a subtle pitfall because of the format 'dd-MON-yy'.

With a different language setting this might easily fail e.g. TO_DATE('27-MAY-12','dd-MON-yy') when NLS_LANG is set to german. Avoid anything in the format that might be different in a different language. Using a four digit year and only numbers e.g. 'dd-mm-yyyy' or 'yyyy-mm-dd'

In C++-11 you can do:

std::vector<int> v = {0, 1, 2, 3, 4, 5};
for (auto i : v)
{
   // access by value, the type of i is int
   std::cout << i << ' ';
}
std::cout << '\n';

See here for variations: https://en.cppreference.com/w/cpp/language/range-for

I would use .*. . matches any character, * signifies 0 or more occurrences. You might need a DOTALL switch to the regex to capture new lines with ..

I'm new to node.js (about 2 weeks), but I've just created a module that recursively reports to the console the contents of an object. It will list all or search for a specific item and then drill down by a given depth if need be.

Perhaps you can customize this to fit your needs. Keep It Simple! Why complicate?...

'use strict';

//console.log("START: AFutils");

// Recusive console output report of an Object
// Use this as AFutils.reportObject(req, "", 1, 3); // To list all items in req object by 3 levels
// Use this as AFutils.reportObject(req, "headers", 1, 10); // To find "headers" item and then list by 10 levels
// yes, I'm OLD School!  I like to see the scope start AND end!!!  :-P
exports.reportObject = function(obj, key, level, deep) 
{
    if (!obj)
    { 
        return;
    }

    var nextLevel = level + 1;

    var keys, typer, prop;
    if(key != "")
    {   // requested field
        keys = key.split(']').join('').split('[');
    }
    else
    {   // do for all
        keys = Object.keys(obj);
    }
    var len = keys.length;
    var add = "";
    for(var j = 1; j < level; j++)
    {
        // I would normally do {add = add.substr(0, level)} of a precreated multi-tab [add] string here, but Sublime keeps replacing with spaces, even with the ["translate_tabs_to_spaces": false] setting!!! (angry)
        add += "\t";
    }

    for (var i = 0; i < len; i++) 
    {
        prop = obj[keys[i]];
        if(!prop)
        {
            // Don't show / waste of space in console window...
            //console.log(add + level + ": UNDEFINED [" + keys[i] + "]");
        }
        else
        {
            typer = typeof(prop);
            if(typer == "function")
            {
                // Don't bother showing fundtion code...
                console.log(add + level + ": [" + keys[i] + "] = {" + typer + "}");
            }
            else
            if(typer == "object")
            {
                console.log(add + level + ": [" + keys[i] + "] = {" + typer + "}");
                if(nextLevel <= deep)
                {
                    // drop the key search mechanism if first level item has been found...
                    this.reportObject(prop, "", nextLevel, deep); // Recurse into
                }
            }
            else
            {
                // Basic report
                console.log(add + level + ": [" + keys[i] + "] = {" + typer + "} = " + prop + ".");
            }
        }
    }

I know this post is kind of old but after spending many hours on trying to make the fonts work on my nginx local machine and trying a tons of solutions i finally got the one that worked for me like a charm.

location ~* \.(eot|otf|ttf|woff|woff2)$ {
    add_header Access-Control-Allow-Origin *;
}

Inside the parenthesis you can put the extensions of your fonts or generally the files that you want to load. For example i used it for fonts and for images(png,jpg etc etc) as well so don't get confused that this solution applies only for fonts.

Just put it into your nginx config file, restart and i hope it works also for you!

I have found different results to be true. I am trying to replace all whitespace with a single space and the regex was extremely slow.

return( Regex::Replace( text, L"\s+", L" " ) );

What worked the most optimally for me (in C++ cli) was:

String^ ReduceWhitespace( String^ text )
{
  String^ newText;
  bool    inWhitespace = false;
  Int32   posStart = 0;
  Int32   pos      = 0;
  for( pos = 0; pos < text->Length; ++pos )
  {
    wchar_t cc = text[pos];
    if( Char::IsWhiteSpace( cc ) )
    {
      if( !inWhitespace )
      {
        if( pos > posStart ) newText += text->Substring( posStart, pos - posStart );
        inWhitespace = true;
        newText += L' ';
      }
      posStart = pos + 1;
    }
    else
    {
      if( inWhitespace )
      {
        inWhitespace = false;
        posStart = pos;
      }
    }
  }

  if( pos > posStart ) newText += text->Substring( posStart, pos - posStart );

  return( newText );
}

I tried the above routine first by replacing each character separately, but had to switch to doing substrings for the non-space sections. When applying to a 1,200,000 character string:

• the above routine gets it done in 25 seconds
• the above routine + separate character replacement in 95 seconds
• the regex aborted after 15 minutes.

First the mysqldump command is executed and the output generated is redirected using the pipe. The pipe is sending the standard output into the gzip command as standard input. Following the filename.gz, is the output redirection operator (>) which is going to continue redirecting the data until the last filename, which is where the data will be saved.

For example, this command will dump the database and run it through gzip and the data will finally land in three.gz

mysqldump -u user -pupasswd my-database | gzip > one.gz > two.gz > three.gz

$> ls -l
-rw-r--r--  1 uname  grp     0 Mar  9 00:37 one.gz
-rw-r--r--  1 uname  grp  1246 Mar  9 00:37 three.gz
-rw-r--r--  1 uname  grp     0 Mar  9 00:37 two.gz

My original answer is an example of redirecting the database dump to many compressed files (without double compressing). (Since I scanned the question and seriously missed - sorry about that)

This is an example of recompressing files:

mysqldump -u user -pupasswd my-database | gzip -c > one.gz; gzip -c one.gz > two.gz; gzip -c two.gz > three.gz

$> ls -l
-rw-r--r--  1 uname  grp  1246 Mar  9 00:44 one.gz
-rw-r--r--  1 uname  grp  1306 Mar  9 00:44 three.gz
-rw-r--r--  1 uname  grp  1276 Mar  9 00:44 two.gz

This is a good resource explaining I/O redirection: http://www.codecoffee.com/tipsforlinux/articles2/042.html

I believe they can be up to 2^31-1 characters, as they are held by an internal array, and arrays are indexed by integers in Java.

the value of the input text box, during onKeyPress is always the value before the change

This is on purpose: This allows the event listener to cancel the keypress.

If the event listeners cancels the event, the value is not updated. If the event is not canceled, the value is updated, but after the event listener was called.

To get the value after the field value has been updated, schedule a function to run on the next event loop. The usual way to do this is to call setTimeout with a timeout of 0:

$('#field').keyup(function() {
    var $field = $(this);

    // this is the value before the keypress
    var beforeVal = $field.val();

    setTimeout(function() {

        // this is the value after the keypress
        var afterVal = $field.val();
    }, 0);
});

Try here: http://jsfiddle.net/Q57gY/2/

Edit: Some browsers (e.g. Chrome) do not trigger keypress events for backspace; changed keypress to keyup in code.

Here's another way:

var myspan = document.getElementById('myspan');

if (myspan.innerText) {
    myspan.innerText = "newtext";
}
else
if (myspan.textContent) {
        myspan.textContent = "newtext";   
}

The innerText property will be detected by Safari, Google Chrome and MSIE. For Firefox, the standard way of doing things was to use textContent but since version 45 it too has an innerText property, as someone kindly apprised me recently. This solution tests to see if a browser supports either of these properties and if so, assigns the "newtext".

To copy an exact string (literal in this case):

Clipboard.SetText("Hello, clipboard");

To copy the contents of a textbox either use TextBox.Copy() or get text first and then set clipboard value:

Clipboard.SetText(txtClipboard.Text);

See here for an example. Or... Official MSDN documentation or Here for WPF.

Remarks:

• Clipboard is desktop UI concept, trying to set it in server side code like ASP.Net will only set value on the server and has no impact on what user can see in they browser. While linked answer lets one to run Clipboard access code server side with SetApartmentState it is unlikely what you want to achieve.

• If after following information in this question code still gets an exception see "Current thread must be set to single thread apartment (STA)" error in copy string to clipboard

• This question/answer covers regular .NET, for .NET Core see - .Net Core - copy to clipboard?

I have had lots of issues with hidden and not visible inputs over the past decade sometimes things are way simpler than we think.

I have had a little wish with IE 5,6,7,8 and 9 for not supporting the opacity and thus the file input would cover the upload image however the following css code has resolved the issue.

-ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";
filter: alpha(opacity=0);  

The following snipped is tested on chrome, IE 5,6,7,8,9,10 the only issue in IE 5 is that it does not support auto margin.

Use event.key and modern JS!

No number codes anymore. You can check key directly. For example "Enter", "LeftArrow", "r", or "R".

const input = document.getElementById("searchbox");
input.addEventListener("keypress", function onEvent(event) {
    if (event.key === "Enter") {
        // Submit
    }
    else if (event.key === "Q") {
        // Play quacking duck sound, maybe...
    }
});

STATIC_ROOT = 'static/'

STATIC_URL = '/static/'

STATICFILES_DIRS = (

npm uninstall -g angular-cli

Reinstall (with yarn)

# npm install --global yarn
yarn global add @angular/cli@latest
ng set --global packageManager=yarn  # This will help ng-cli to use yarn

npm install --global @angular/cli@latest

Another way is to not use global install, and add /node_modules/.bin folder in the PATH, or use npm scripts. It will be softer to upgrade.

Raymond Chen gives a nice overview of what __stdcall and __cdecl does.

(1) The caller "knows" to clean up the stack after calling a function because the compiler knows the calling convention of that function and generates the necessary code.

void __stdcall StdcallFunc() {}

void __cdecl CdeclFunc()
{
    // The compiler knows that StdcallFunc() uses the __stdcall
    // convention at this point, so it generates the proper binary
    // for stack cleanup.
    StdcallFunc();
}

It is possible to mismatch the calling convention, like this:

LRESULT MyWndProc(HWND hwnd, UINT msg,
    WPARAM wParam, LPARAM lParam);
// ...
// Compiler usually complains but there's this cast here...
windowClass.lpfnWndProc = reinterpret_cast<WNDPROC>(&MyWndProc);

So many code samples get this wrong it's not even funny. It's supposed to be like this:

// CALLBACK is #define'd as __stdcall
LRESULT CALLBACK MyWndProc(HWND hwnd, UINT msg
    WPARAM wParam, LPARAM lParam);
// ...
windowClass.lpfnWndProc = &MyWndProc;

However, assuming the programmer doesn't ignore compiler errors, the compiler will generate the code needed to clean up the stack properly since it'll know the calling conventions of the functions involved.

(2) Both ways should work. In fact, this happens quite frequently at least in code that interacts with the Windows API, because __cdecl is the default for C and C++ programs according to the Visual C++ compiler and the WinAPI functions use the __stdcall convention.

(3) There should be no real performance difference between the two.

For example: you populated your UIPickerView with array values, then you wanted 

to select a certain array value in the first load of pickerView like "Arizona". Note that the word "Arizona" is at index 2. This how to do it :) Enjoy coding.

NSArray *countryArray =[NSArray arrayWithObjects:@"Alabama",@"Alaska",@"Arizona",@"Arkansas", nil];
UIPickerView *countryPicker=[[UIPickerView alloc]initWithFrame:self.view.bounds];
countryPicker.delegate=self;
countryPicker.dataSource=self;
[countryPicker selectRow:2 inComponent:0 animated:YES];
[self.view addSubview:countryPicker];

I've found something which is working, it can save lives !

private $userList = array();
$userList = User::fetchAll(); // now $userList is an array of User objects
foreach ($userList as $user) {
   $user instanceof User;
   echo $user->getName();
}

I have a search form with an icon that clears the text when clicked. However, the problem (on mobile & tablets) was that the keyboard would collapse/hide, as the click event removed focus was removed from the input.

Goal: after clearing the search form (clicking/tapping on x-icon) keep the keyboard visible!

To accomplish this, apply stopPropagation() on the event like so:

function clear ($event) {
    $event.preventDefault();
    $event.stopPropagation();
    self.query = '';
    $timeout(function () {
        document.getElementById('sidebar-search').focus();
    }, 1);
}

And the HTML form:

<form ng-controller="SearchController as search"
    ng-submit="search.submit($event)">
        <input type="search" id="sidebar-search" 
            ng-model="search.query">
                <span class="glyphicon glyphicon-remove-circle"
                    ng-click="search.clear($event)">
                </span>
</form>

I like this way:

using System.Globalization;
...
TextInfo myTi = new CultureInfo("en-Us",false).TextInfo;
string raw = "THIS IS ALL CAPS";
string firstCapOnly = myTi.ToTitleCase(raw.ToLower());

Lifted from this MSDN article.

Since the OP asked for the list of the tensors instead of the list of operations/nodes, the code should be slightly different:

graph = tf.get_default_graph()    
tensors_per_node = [node.values() for node in graph.get_operations()]
tensor_names = [tensor.name for tensors in tensors_per_node for tensor in tensors]

Very much agreed with @Patrik M, but the thing with Arrays.toString is that it includes "[" and "]" and "," in the output. So I'll simply use a regex to remove them from outout like this

String strOfInts = Arrays.toString(intArray).replaceAll("\\[|\\]|,|\\s", "");

and now you have a String which can be parsed back to java.lang.Number, for example,

long veryLongNumber = Long.parseLong(intStr);

Or you can use the java 8 streams, if you hate regex,

String strOfInts = Arrays
            .stream(intArray)
            .mapToObj(String::valueOf)
            .reduce((a, b) -> a.concat(",").concat(b))
            .get();

Another possibility is too many threads. We just ran into this error message when running a test harness against an app that uses a thread pool. We used

watch -n 5 -d "ps -eL <java_pid> | wc -l"

to watch the ongoing count of Linux native threads running within the given Java process ID. After this hit about 1,000 (for us--YMMV), we started getting the error message you mention.

A trivial

$num = $num <= 0 ? $num : -$num ;

or, the better solution, IMHO:

$num = -1 * abs($num)

As @VegardLarsen has posted,

the explicit multiplication can be avoided for shortness but I prefer readability over shortness

I suggest to avoid if/else (or equivalent ternary operator) especially if you have to manipulate a number of items (in a loop or using a lambda function), as it will affect performance.

"If the float is a negative, make it a positive."

In order to change the sign of a number you can simply do:

$num = 0 - $num;

or, multiply it by -1, of course :)

This is a working example:

jdbc:mysql://localhost:3306/database?useUnicode=yes&characterEncoding=UTF-8&serverTimezone=Europe/Moscow

Try using the SQL_NO_CACHE (MySQL 5.7) option in your query. (MySQL 5.6 users click HERE )

eg.

SELECT SQL_NO_CACHE * FROM TABLE

This will stop MySQL caching the results, however be aware that other OS and disk caches may also impact performance. These are harder to get around.

.....

$("#testID #testID2").removeClass("test2").addClass("test3");

Because you have assigned an id to img too, you can simply do this too:

$("#testID2").removeClass("test2").addClass("test3");

And finally, you can do this too:

$("#testID img").removeClass("test2").addClass("test3");

I see two options here

var link = $('a').attr('href');
var equalPosition = link.indexOf('='); //Get the position of '='
var number = link.substring(equalPosition + 1); //Split the string and get the number.

I dont know if you're gonna use it for paging and have the text in the <a>-tag as you have it, but if you should you can also do

var number = $('a').text();

For this there are two cases

Case 1: File already added to git repo.

Case 2: File newly created and its status still showing as untracked file when using

git status

If you have case 1:

STEP 1: Then run

git rm --cached filename 

to remove it from git repo cache

if it is a directory then use

git rm -r --cached  directory_name

STEP 2: If Case 1 is over then create new file named .gitignore in your git repo

STEP 3: Use following to tell git to ignore / assume file is unchanged

git update-index --assume-unchanged path/to/file.txt

STEP 4: Now, check status using git status open .gitignore in your editor nano, vim, geany etc... any one, add the path of the file / folder to ignore. If it is a folder then user folder_name/* to ignore all file.

If you still do not understand read the article git ignore file link.

If we want to change the content of <div> tag whenever the function image()is called, we have to do like this:

Javascript

function image() {
    var img = document.createElement("IMG");
    img.src = "/images/img1.gif";
    $('#image').html(img); 
}

HTML

<div id="image"></div>
<div><a href="javascript:image();">First Image</a></div>

Use chars:

Dim firstChar As char;
firstChar = s.Chars(0);

http://vb.net-informations.com/string/vb.net_String_Chars.htm

You first need to understand that your application classes themselves are instantiated to java.class.Class objects during runtime. This is when your static blocks are ran. So you can actually do this:

public class Main {

    private static int myInt;

    static {
        myInt = 1;
        System.out.println("myInt is 1");
    }

    //  needed only to run this class
    public static void main(String[] args) {
    }

}

and it would print "myInt is 1" to console. Note that I haven't instantiated any class.

In my case i had to load images on radio button click, I just uses the regular onclick event and it worked for me.

 <input type="radio" name="colors" value="{{color.id}}" id="{{color.id}}-option" class="color_radion"  onclick="return get_images(this, {{color.id}})">

<script>
  function get_images(obj, color){
    console.log($("input[type='radio'][name='colors']:checked").val());

  }
  </script>

Try this:

select CONVERT(datetime, convert(varchar(10), 20120103))

You are producing a filtered list by using a list comprehension. i is still being bound to each and every element of that list, and the last element is still 'three', even if it was subsequently filtered out from the list being produced.

You should not use a list comprehension to pick out one element. Just use a for loop, and break to end it:

for elem in my_list:
    if elem == 'two':
        break

If you must have a one-liner (which would be counter to Python's philosophy, where readability matters), use the next() function and a generator expression:

i = next((elem for elem in my_list if elem == 'two'), None)

which will set i to None if there is no such matching element.

The above is not that useful a filter; your are essentially testing if the value 'two' is in the list. You can use in for that:

elem = 'two' if 'two' in my_list else None

The problem in here is ms excel not recognizing the things which we entered as date, though is appears as date in menu bar. Select cell and type "=istext(cell ad)" then you can see it "TRUE" hence still your date ms excel thinks as a text that is why it aligns to left automatically. So we should change the type of text. There are many types of changing methods. but I think this too easy and lets do it now.

SELECT THE CELLS -> Go DATA in menu bar -> Then select "Text to Columns" object -> Select "Delimited" in first window then click next -> remove all ticks in the second window and hit next button -> last window select the "Date" and select your prefer date format then hit the finish button.(Then dates look like Wednesday, March 14, 2012) Then you can using previously used formula use and check whether our date is recognized in excel. Then you can Sort as you want. Thank you

I wonder why nobody mentioned the Minted package. It has far better syntax highlighting than the LaTeX listing package. It uses Pygments.

$ pip install Pygments

Example in LaTeX:

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}

\usepackage{minted}

\begin{document}
\begin{minted}{python}
import numpy as np

def incmatrix(genl1,genl2):
    m = len(genl1)
    n = len(genl2)
    M = None #to become the incidence matrix
    VT = np.zeros((n*m,1), int)  #dummy variable

    #compute the bitwise xor matrix
    M1 = bitxormatrix(genl1)
    M2 = np.triu(bitxormatrix(genl2),1) 

    for i in range(m-1):
        for j in range(i+1, m):
            [r,c] = np.where(M2 == M1[i,j])
            for k in range(len(r)):
                VT[(i)*n + r[k]] = 1;
                VT[(i)*n + c[k]] = 1;
                VT[(j)*n + r[k]] = 1;
                VT[(j)*n + c[k]] = 1;

                if M is None:
                    M = np.copy(VT)
                else:
                    M = np.concatenate((M, VT), 1)

                VT = np.zeros((n*m,1), int)

    return M

Here's my answer for those that are Googling:

CSS:

.column {
    float: left;
    width: 50%;
}

/* Clear floats after the columns */
.container:after {
    content: "";
    display: table;
    clear: both;
}

Here's the HTML:

<div class="container">
    <div class="column"></div>
    <div class="column"></div>
</div>

Pass the arguments to the run command from within gdb.

$ gdb ./a.out
(gdb) r < t
Starting program: /dir/a.out < t

Simply drag a ContextMenu or ContextMenuStrip component into your form and visually design it, then assign it to the ContextMenu or ContextMenuStrip property of your desired control.

That's a half-open interval.

• A closed interval [a,b] includes the end points.
• An open interval (a,b) excludes them.

In your case the end-point at the start of the interval is included, but the end is excluded. So it means the interval "first1 <= x < last1".

Half-open intervals are useful in programming because they correspond to the common idiom for looping:

for (int i = 0; i < n; ++i) { ... } 

Here i is in the range [0, n).

You need to use the SUBTOTAL function. The SUBTOTAL function ignores rows that have been excluded by a filter.

The formula would look like this:

=SUBTOTAL(9,B1:B20)

The function number 9, tells it to use the SUM function on the data range B1:B20.

If you are 'filtering' by hiding rows, the function number should be updated to 109.

=SUBTOTAL(109,B1:B20)

The function number 109 is for the SUM function as well, but hidden rows are ignored.

For who uses Gradle can also avail the same:

Go to: 1. View --> Tool Windows --> Gradle 2. Click on the + button and add your build.gradle file

You can use time and subshell ():

time (
  for (( i=1; i<10000; i++ )); do
    echo 1 >/dev/null
  done
)

Or in same shell {}:

time {
  for (( i=1; i<10000; i++ )); do
    echo 1 >/dev/null
  done
}

There's a setSeconds method as well:

var t = new Date();
t.setSeconds(t.getSeconds() + 10);

For a list of the other Date functions, you should check out MDN

setSeconds will correctly handle wrap-around cases:

var d;_x000D_
d = new Date('2014-01-01 10:11:55');_x000D_
alert(d.getMinutes() + ':' + d.getSeconds()); //11:55_x000D_
d.setSeconds(d.getSeconds() + 10);_x000D_
alert(d.getMinutes() + ':0' + d.getSeconds()); //12:05

I think this is what you want:

REGEX_DATE='^\d{2}[/-]\d{2}[/-]\d{4}$'

echo "$1" | grep -P -q $REGEX_DATE
echo $?

I've used the -P switch to get perl regex.

If you are inside a .then() block and you want to execute a settimeout()

            .then(() => {
                console.log('wait for 10 seconds . . . . ');
                return new Promise(function(resolve, reject) { 
                    setTimeout(() => {
                        console.log('10 seconds Timer expired!!!');
                        resolve();
                    }, 10000)
                });
            })
            .then(() => {
                console.log('promise resolved!!!');

            })

output will as shown below

wait for 10 seconds . . . .
10 seconds Timer expired!!!
promise resolved!!!

Happy Coding!

Here's a very concise and recursive solution that allows you to input the size of the output permutations similar to the statistical operator nPr. "5 permutation 3". This allows you to get all possible permutations with a specific size.

function generatePermutations(list, size=list.length) {
    if (size > list.length) return [];
    else if (size == 1) return list.map(d=>[d]); 
    return list.flatMap(d => generatePermutations(list.filter(a => a !== d), size - 1).map(item => [d, ...item]));
}

generatePermutations([1,2,3])

[[1, 2, 3],[1, 3, 2], [2, 1, 3], [2, 3, 1], [3, 1, 2], [3, 2, 1]]

generatePermutations([1,2,3],2)

[[1, 2], [1, 3], [2, 1], [2, 3], [3, 1], [3, 2]]

To reference a commit, simply write its SHA-hash, and it'll automatically get turned into a link.

You could also do it with a Func like this

@{
    var getStyle = new Func<int, int, string>((width, margin) => string.Format("width: {0}px; margin: {1}px;", width, margin));
}

<div style="@getStyle(50, 2)"></div>

Try this steps:

1. unplug device
2. adb kill-server
3. adb start-server
4. plug device

You need to allow Allow USB debugging in your device when popup.

If you can't use the delay method as Robert Harvey suggested, you can use setTimeout.

Eg.

setTimeout(function() {$("#test").animate({"top":"-=80px"})} , 1500); // delays 1.5 sec
setTimeout(function() {$("#test").animate({"opacity":"0"})} , 1500 + 1000); // delays 1 sec after the previous one

It's perhaps a bit of a kludge, but the following code does what you seem to want to do:

Set rng = wks.Range(wks.Rows(iStartRow), wks.Rows(iEndRow)).Rows

Use VisualTreeHelper.GetParent or the recursive function below to find the parent window.

public static Window FindParentWindow(DependencyObject child)
{
    DependencyObject parent= VisualTreeHelper.GetParent(child);

    //CHeck if this is the end of the tree
    if (parent == null) return null;

    Window parentWindow = parent as Window;
    if (parentWindow != null)
    {
        return parentWindow;
    }
    else
    {
        //use recursion until it reaches a Window
        return FindParentWindow(parent);
    }
}

This is another option:

export default function Counter() {

}

agenda is a Lightweight job scheduling for node. This will help you.

There is the function in guava libraries:

LongMath.log2()

So I suggest to use it.

Try this (Note: I don't have right now Visual Studio ,so code is copy paste from my archive(I haven't test it) :

Private Sub DataGridView1_CellFormatting(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles DataGridView1.CellFormatting
    Dim drv As DataRowView
    If e.RowIndex >= 0 Then
        If e.RowIndex <= ds.Tables("Products").Rows.Count - 1 Then
            drv = ds.Tables("Products").DefaultView.Item(e.RowIndex)
            Dim c As Color
            If drv.Item("Quantity").Value < 5  Then
                c = Color.LightBlue
            Else
                c = Color.Pink
            End If
            e.CellStyle.BackColor = c
        End If
    End If
End Sub

You need to explicitly define operator == for MyStruct1.

struct MyStruct1 {
  bool operator == (const MyStruct1 &rhs) const
  { /* your logic for comparision between "*this" and "rhs" */ }
};

Now the == comparison is legal for 2 such objects.

TL;DR To fix this issue, invoke packaging plugin before, e.g. for jar packaging use maven-jar-plugin , as following:

mvn jar:jar install:install

Or

mvn jar:jar deploy:deploy 

If you actually needed to deploy.

Gotcha This approach won't work if you have multi-module project with different packagings (ear/war/jar/zip) – even worse, wrong artifacts will be installed/deployed! In such case use reactor options to only build the deployable module (e.g. the war).

Explanation

In some cases you actually want to run directly a install:install or deploy:deploy goal (that is, from the maven-deploy-plugin, the deploy goal, not the Maven deploy phase) and you would end up in the annoying The packaging for this project did not assign a file to the build artifact.

A classic example is a CI job (a Jenkins or Bamboo job, e.g.) where in different steps you want to execute/care about different aspects:

• A first step would be a mvn clean install, performing tests and test coverage
• A second step would be a Sonarqube analysis based on a quality profile, e.g. mvn sonar:sonar plus further options
• Then, and only after successful tests execution and quality gate passed, you want to deploy to your Maven enterprise repository the final project artifacts, yet you don't want to re-run mvn deploy, because it would again execute previous phases (and compile, test, etc.) and you want your build to be effective but yet fast.

Yes, you could speed up this last step at least skipping tests (compilation and execution, via -Dmaven.test.skip=true) or play with a particular profile (to skip as many plugins as possible), but it is much easier and clear to simply run mvn deploy:deploy then.

But it would fail with the error above, because as also specified by the plugin FAQ:

During the packaging-phase all gathered and placed in context. With this mechanism Maven can ensure that the maven-install-plugin and maven-deploy-plugin are copying/uploading the same set of files. So when you only execute deploy:deploy, then there are no files put in the context and there is nothing to deploy.

Indeed, the deploy:deploy needs some runtime information placed in the build context by previous phases (or previous plugins/goals executions).

It has also reported as a potential bug: MDEPLOY-158: deploy:deploy does not work for only Deploying artifact to Maven Remote repo

But then rejected as not a problem.

The deployAtEnd configuration option of the maven-deploy-plugin won't help neither in certain scenarios because we have intermediate job steps to execute:

Whether every project should be deployed during its own deploy-phase or at the end of the multimodule build. If set to true and the build fails, none of the reactor projects is deployed. (experimental)

So, how to fix it?
Simply run the following in such a similar third/last step:

mvn jar:jar deploy:deploy

The maven-jar-plugin will not re-create any jar as part of your build, thanks to its forceCreation option set to false by default:

Require the jar plugin to build a new JAR even if none of the contents appear to have changed. By default, this plugin looks to see if the output jar exists and inputs have not changed. If these conditions are true, the plugin skips creation of the jar.

But it will nicely populate the build context for us and make deploy:deploy happy. No tests to skip, no profiles to add. Just what you need: speed.

Additional note: if you are using the build-helper-maven-plugin, buildnumber-maven-plugin or any other similar plugin to generate meta-data later on used by the maven-jar-plugin (e.g. entries for the Manifest file), you most probably have executions linked to the validate phase and you still want to have them during the jar:jar build step (and yet keep a fast execution). In this case the almost harmless overhead is to invoke the validate phase as following:

mvn validate jar:jar deploy:deploy

Yet another additional note: if you have not jar but, say, war packaging, use war:war before install/deploy instead.

Gotcha as pointed out above, check behavior in multi module projects.

Using WIN + Q worked for me. Just q alone gave me "command not found" and eventually it jumped back into the git diff insanity.

For posterity, I think this is quicker:

a = np.array([np.array(list()) for _ in y])

You might even be able to pass in a generator (i.e. [] -> ()), in which case the inner list is never fully stored in memory.

Responding to comment below:

>>> import numpy as np
>>> y = range(10)
>>> a = np.array([np.array(list) for _ in y])
>>> a
array([array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object)], dtype=object)

Initially, the result set object (rs) points to the BFR (before first record). Once we use rs.next(), the cursor points to the first record and the rs holds "true". Using the while loop you can print all the records of the table. After all the records are retrieved, the cursor moves to ALR (After last record) and it will be set to null. Let us consider that there are 2 records in the table.

if(rs.next()==false){
    // there are no records found
    }    

while (rs.next()==true){
    // print all the records of the table
    }

In short hand, we can also write the condition as while (rs.next()).

The real answer is you need to set the escape character to '\': SET ESCAPE ON

The problem may have occurred either because escaping was disabled, or the escape character was set to something other than '\'. The above statement will enable escaping and set it to '\'.

None of the other answers previously posted actually answer the original question. They all work around the problem but don't resolve it.

This means that you must declare strict mode by writing "use strict" at the beginning of the file or the function to use block-scope declarations.

EX:

function test(){
    "use strict";
    let a = 1;
} 

A very simple way of doing this (using Storyboards, for example) is:

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"SomeStoryboard" bundle:nil];
UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"SomeStoryboardViewController"];
// the key for what you're looking to do:
vc.modalPresentationStyle = UIModalPresentationOverCurrentContext;
vc.view.alpha = 0.50f;

[self presentViewController:vc animated:YES completion:^{
    // great success
}];

This will present a UIViewController in a Storyboard modally, but with a translucent background.

I found this to be exactly what I was looking for related to key binding in WPF:

<Window.InputBindings>
        <KeyBinding Modifiers="Control"
                    Key="N"
                    Command="{Binding CreateCustomerCommand}" />
</Window.InputBindings>

See blog post MVVM CommandReference and KeyBinding

I try to explain the Bayes rule with an example.

What is the chance that a random person selected from the society is a smoker?

You may reply 10%, and let's assume that's right.

Now, what if I say that the random person is a man and is 15 years old?

You may say 15 or 20%, but why?.

In fact, we try to update our initial guess with new pieces of evidence ( P(smoker) vs. P(smoker | evidence) ). The Bayes rule is a way to relate these two probabilities.

P(smoker | evidence) = P(smoker)* p(evidence | smoker)/P(evidence)

Each evidence may increase or decrease this chance. For example, this fact that he is a man may increase the chance provided that this percentage (being a man) among non-smokers is lower.

In the other words, being a man must be an indicator of being a smoker rather than a non-smoker. Therefore, if an evidence is an indicator of something, it increases the chance.

But how do we know that this is an indicator?

For each feature, you can compare the commonness (probability) of that feature under the given conditions with its commonness alone. (P(f | x) vs. P(f)).

P(smoker | evidence) / P(smoker) = P(evidence | smoker)/P(evidence)

For example, if we know that 90% of smokers are men, it's not still enough to say whether being a man is an indicator of being smoker or not. For example if the probability of being a man in the society is also 90%, then knowing that someone is a man doesn't help us ((90% / 90%) = 1. But if men contribute to 40% of the society, but 90% of the smokers, then knowing that someone is a man increases the chance of being a smoker (90% / 40%) = 2.25, so it increases the initial guess (10%) by 2.25 resulting 22.5%.

However, if the probability of being a man was 95% in the society, then regardless of the fact that the percentage of men among smokers is high (90%)! the evidence that someone is a man decreases the chance of him being a smoker! (90% / 95%) = 0.95).

So we have:

P(smoker | f1, f2, f3,... ) = P(smoker) * contribution of f1* contribution of f2 *... 
=
P(smoker)* 
(P(being a man | smoker)/P(being a man))*
(P(under 20 | smoker)/ P(under 20))

Note that in this formula we assumed that being a man and being under 20 are independent features so we multiplied them, it means that knowing that someone is under 20 has no effect on guessing that he is man or woman. But it may not be true, for example maybe most adolescence in a society are men...

To use this formula in a classifier

The classifier is given with some features (being a man and being under 20) and it must decide if he is an smoker or not (these are two classes). It uses the above formula to calculate the probability of each class under the evidence (features), and it assigns the class with the highest probability to the input. To provide the required probabilities (90%, 10%, 80%...) it uses the training set. For example, it counts the people in the training set that are smokers and find they contribute 10% of the sample. Then for smokers checks how many of them are men or women .... how many are above 20 or under 20....In the other words, it tries to build the probability distribution of the features for each class based on the training data.

I have spent the last few days trying to figure this out myself. Using the old json dataType gives you cross origin problems, while setting the dataType to jsonp makes the data "unreadable" as explained above. So there are apparently two ways out, the first hasn't worked for me but seems like a potential solution and that I might be doing something wrong. This is explained here [ https://learn.jquery.com/ajax/working-with-jsonp/ ].

The one that worked for me is as follows: 1- download the ajax cross origin plug in [ http://www.ajax-cross-origin.com/ ]. 2- add a script link to it just below the normal jQuery link. 3- add the line "crossOrigin: true," to your ajax function.

Good to go! here is my working code for this:

  $.ajax({_x000D_
      crossOrigin: true,_x000D_
      url : "https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=-33.86,151.195&radius=5000&type=ATM&keyword=ATM&key=MyKey",_x000D_
      type : "GET",_x000D_
      success:function(data){_x000D_
         console.log(data);_x000D_
      }_x000D_
    })

If AddDbContext is used, then also ensure that your DbContext type accepts a DbContextOptions object in its constructor and passes it to the base constructor for DbContext.

The error message says your DbContext(LogManagerContext ) needs a constructor which accepts a DbContextOptions. But i couldn't find such a constructor in your DbContext. So adding below constructor probably solves your problem.

    public LogManagerContext(DbContextOptions options) : base(options)
    {
    }

Edit for comment

If you don't register IHttpContextAccessor explicitly, use below code:

services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>(); 

In short, no. If someone can view an image or video in their browser then they have, by definition, downloaded it. That's how the web works - it is client server based. Whatever you can view in your browser (client) has been transfered to your computer from the remote website (server).

function test() {
 alert('called!');
}
var id = setInterval('test();', 10000); //call test every 10 seconds.
function stop() { // call this to stop your interval.
   clearInterval(id);
}

In mysql your query should be like

ALTER TABLE table_name change column_1 column_2 Data_Type;

you have written the query in Oracle.

If you are willing to put a container element around your image, a pure CSS solution is simple. You see, 99% height has no meaning when the parent element will extend vertically to contain its children. The parent needs to have a fixed height, say... the height of the viewport.

HTML

<!-- use a tall image to illustrate the problem -->
<div class='fill-screen'>
    <img class='make-it-fit' 
         src='https://upload.wikimedia.org/wikipedia/commons/f/f2/Leaning_Tower_of_Pisa.jpg'>
</div>

CSS

div.fill-screen {
    position: fixed;
    left: 0;
    right: 0;
    top: 0;
    bottom: 0;
    text-align: center;
}

img.make-it-fit {
    max-width: 99%;
    max-height: 99%;
}

Play with the fiddle.

If you run your commands in a shell you can write something like "java -cp" and add any directories you want separated by ":" if java doesnt find something in one directory it will go try and find them in the other directories, that is what I do.

From inside the Service class:

Intent dialogIntent = new Intent(this, MyActivity.class);
dialogIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(dialogIntent);

Not seeing it mentioned here, but also possible to use the vue-property-decorator pattern if you are extending your Vue class.

import { Watch, Vue } from 'vue-property-decorator';

export default class SomeClass extends Vue {
   ...

   @Watch('item.someOtherProp')
   someOtherPropChange(newVal, oldVal) {
      // do something
   }

   ...
}

I faced similar issue "CrashLoopBackOff" when I debugged getting pods and logs of pod. Found out that my command arguments are wrong

What I did was peculiar but somehow it fixed the problem. Pick any project and perform a fake edit of the build.properties file (e.g., add and remove a space and then save the file). Clean and rebuild the projects in your workspace.

Hope this solve some of your problems.

The docs are pretty clear on this: HashSet.add doesn't replace:

Adds the specified element to this set if it is not already present. More formally, adds the specified element e to this set if this set contains no element e2 such that (e==null ? e2==null : e.equals(e2)). If this set already contains the element, the call leaves the set unchanged and returns false.

But HashMap.put will replace:

If the map previously contained a mapping for the key, the old value is replaced.

Unnamed namespaces are a utility to make an identifier translation unit local. They behave as if you would choose a unique name per translation unit for a namespace:

namespace unique { /* empty */ }
using namespace unique;
namespace unique { /* namespace body. stuff in here */ }

The extra step using the empty body is important, so you can already refer within the namespace body to identifiers like ::name that are defined in that namespace, since the using directive already took place.

This means you can have free functions called (for example) help that can exist in multiple translation units, and they won't clash at link time. The effect is almost identical to using the static keyword used in C which you can put in in the declaration of identifiers. Unnamed namespaces are a superior alternative, being able to even make a type translation unit local.

namespace { int a1; }
static int a2;

Both a's are translation unit local and won't clash at link time. But the difference is that the a1 in the anonymous namespace gets a unique name.

Read the excellent article at comeau-computing Why is an unnamed namespace used instead of static? (Archive.org mirror).

Your ApplicationConfig should register the MultiPartFeature.class from the glassfish.jersey.media.. so as to enable file upload

@javax.ws.rs.ApplicationPath(ResourcePath.API_ROOT)
public class ApplicationConfig extends ResourceConfig {  
public ApplicationConfig() {
        //register the necessary headers files needed from client
        register(CORSConfigurationFilter.class);
        //The jackson feature and provider is used for object serialization
        //between client and server objects in to a json
        register(JacksonFeature.class);
        register(JacksonProvider.class);
        //Glassfish multipart file uploader feature
        register(MultiPartFeature.class);
        //inject and registered all resources class using the package
        //not to be tempered with
        packages("com.flexisaf.safhrms.client.resources");
        register(RESTRequestFilter.class);
    }

To pass the parameter you need to use resolve and inject the items in controller

$scope.Edit = function (Id) {
   var modalInstance = $modal.open({
      templateUrl: '/app/views/admin/addeditphone.html',
      controller: 'EditCtrl',
      resolve: {
         editId: function () {
           return Id;
         }
       }
    });
}

Now if you will use like this:

app.controller('EditCtrl', ['$scope', '$location'
       , function ($scope, $location, editId)

in this case editId will be undefined. You need to inject it, like this:

app.controller('EditCtrl', ['$scope', '$location', 'editId'
     , function ($scope, $location, editId)

Now it will work smooth, I face the same problem many time, once injected, everything start working!

Another solution is to use an SVG text node which is supported by most browsers.

<svg width="50" height="300">
    <text x="28" y="150" transform="rotate(-90, 28, 150)" style="text-anchor:middle; font-size:14px">This text is vertical</text>
</svg>

Demo: https://jsfiddle.net/bkymb5kr/

More on SVG text: http://tutorials.jenkov.com/svg/text-element.html

Late but I hope this helps someone.

I have my JAX RS defined like this:

@Path("/examplepath")
@RequestScoped //this make the diference
public class ExampleResource {

Then, in my code finally I can inject:

@Inject
SomeManagedBean bean;

In my case, the SomeManagedBean is an ApplicationScoped bean.

Hope this helps to anyone.

DO not use the below method to send the data using ajax call

data: '{"jewellerId":"' + filter + '","locale":"' + locale + '"}'

If by mistake user enter special character like single quote or double quote the ajax call fails due to wrong string.

Use below method to call the Web service without any issue

var parameter = {
       jewellerId: filter,
       locale : locale 
};


data: JSON.stringify(parameter)

In above parameter is the name of javascript object and stringify it when passing it to the data attribute of the ajax call.

Short Version

• Merge takes all the changes in one branch and merges them into another branch in one commit.
• Rebase says I want the point at which I branched to move to a new starting point

So when do you use either one?

Merge

• Let's say you have created a branch for the purpose of developing a single feature. When you want to bring those changes back to master, you probably want merge (you don't care about maintaining all of the interim commits).

Rebase

• A second scenario would be if you started doing some development and then another developer made an unrelated change. You probably want to pull and then rebase to base your changes from the current version from the repository.

See answer from Gary Makin. And you need change the format or data. Because the data that you have do not fit under the chosen format. For example this code works correct:

let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "MM-dd-yyyy"
let dateObj = dateFormatter.dateFromString("10 10 2001")
print("Dateobj: \(dateObj)")

In the URL you pointed to, the button_text.xml is being used to set the textColor attribute.That it is reason they had the button_text.xml in res/color folder and therefore they used @color/button_text.xml

But you are trying to use it for background attribute. The background attribute looks for something in res/drawable folder.

check this i got this selector custom button from the internet.I dont have the link.but i thank the poster for this.It helped me.have this in the drawable folder

The below code address the question "How do I add n number of empty columns to my existing dataframe". In the interest of keeping solutions to similar problems in one place, I am adding it here.

Approach 1 (to create 64 additional columns with column names from 1-64)

m = list(range(1,65,1)) 
dd=pd.DataFrame(columns=m)
df.join(dd).replace(np.nan,'') #df is the dataframe that already exists

Approach 2 (to create 64 additional columns with column names from 1-64)

We can take a mysql dump of any particular table with any given condition like below

mysqldump -uusername -p -hhost databasename tablename --skip-lock-tables

If we want to add a specific where condition on table then we can use the following command

mysqldump -uusername -p -hhost databasename tablename --where="date=20140501" --skip-lock-tables

You probably didn't fully deactivate the Conda environment - remember, the command you need to use with Conda is conda deactivate (for older versions, use source deactivate). So it may be wise to start a new shell and activate the environment in that before you try. Then deactivate it.

You can use the command

conda env remove -n ENV_NAME

to remove the environment with that name. (--name is equivalent to -n)

Note that you can also place environments anywhere you want using -p /path/to/env instead of -n ENV_NAME when both creating and deleting environments, if you choose. They don't have to live in your conda installation.

UPDATE, 30 Jan 2019: From Conda 4.6 onwards the conda activate command becomes the new official way to activate an environment across all platforms. The changes are described in this Anaconda blog post

After all above step clean and Rebuild is also a factor.

for (int j=0; j<test.length; j++) {
   System.out.format("%02X ", test[j]);
}
System.out.println();

Here's a short one:

const base = new URL('/', location.href).href;

console.log(base);

You could try this:

if(typeof(results) == "undefined") { 
    return 0;
} else {
    return results[1] || 0;
}

find path/to/the/folders -maxdepth 1 -name "my_*" -type d -delete

-split outputs an array, and you can save it to a variable like this:

$a = -split 'Once  upon    a     time'
$a[0]

Once

Another cute thing, you can have arrays on both sides of an assignment statement:

$a,$b,$c = -split 'Once  upon    a'
$c

a

Our development image only has the Tomcat service installation on it, so setting the environment variables, etc., didn't have any effect. If you need to do this through the Tomcat Windows service, there are a few things you'll need to be aware of:

• David Citron's comment was the last bit that I needed to get my connection working. The hosts file on our machines has localhost commented out (it's supposedly resolved through the DNS, but that doesn't work for the debug connection). I uncommented it and was able to connect.
• If user access control is turned on, you'll need to use your admin credentials to access the services control panel or the Tomcat monitor app or whatever you're using to toggle the server state. The monitor app (documented here) is probably the best, because you can both edit the server settings for the debug options and start and stop the server.
• I thought that perhaps you would need to run Eclipse as an administrator to be able to terminate the Tomcat process, but you don't. Once you have that remote attachment, you're able to work with the service up to termination.

i tried using the same ng-click for two elements with same name showDetail2('abc')

it is working for me . can you check rest of the code which may be breaking you to move further.

here is the sample jsfiddle i tried:

If the data comes from an external library you might need to run the data upate statement within zone.run(...). Inject zone: NgZone for this. If you can run the instantiation of the external library within zone.run() already, then you might not need zone.run() later.

Also, a good reason to use a controller vs. link function (since they both have access to the scope, element, and attrs) is because you can pass in any available service or dependency into a controller (and in any order), whereas you cannot do that with the link function. Notice the different signatures:

controller: function($scope, $exceptionHandler, $attr, $element, $parse, $myOtherService, someCrazyDependency) {...

vs.

link: function(scope, element, attrs) {... //no services allowed

A different perspective to the same problem away from Javascript and using php:

<a data-toggle="modal" href="#myModal">LINK</a>

<div class="modal fade" tabindex="-1" aria-labelledby="gridSystemModalLabel" id="myModal" role="dialog" style="max-width: 90%;">
    <div class="modal-dialog" style="text-align: left;">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal">&times;</button>
                <h4 class="modal-title">Title</h4>
            </div>
            <div class="modal-body">
                <?php include( 'remotefile.php'); ?>
            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
            </div>
        </div>
    </div>
</div>

and put in the remote.php file your basic html source.

This is also possible with Notepad++:

• Go to the search menu, Ctrl + F, and open the Mark tab.

• Check Bookmark line (if there is no Mark tab update to the current version).

• Enter your search term and click Mark All

  • All lines containing the search term are bookmarked.

• Now go to the menu Search → Bookmark → Remove Bookmarked lines

• Done.

yes you can by using static class. like this:

static class Global
{
    private static string _globalVar = "";

    public static string GlobalVar
    {
        get { return _globalVar; }
        set { _globalVar = value; }
    }
}

and for using any where you can write:

GlobalClass.GlobalVar = "any string value"

Use the .css() jQuery manipulators, or better yet just call .show()/.hide() on the image once you've obtained a handle to it (e.g. $('#img' + id)).

BTW, you should not write javascript handlers with the "javascript:" prefix.

If you are trying to insert the therefore symbol into a WORD DOCUMENT

Hold down the ALT key and type 8756

Hope the answer ur question Regards Al~Hash.

Set registry item for your server instance. For example:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL.2\MSSQLServer\BackupDirectory

You can use a timedelta object:

from datetime import datetime, timedelta
    
d = datetime.today() - timedelta(days=days_to_subtract)

This will bring back totals per property and type

SELECT  PropertyID,
        TYPE,
        SUM(Amount)
FROM    yourTable
GROUP BY    PropertyID,
            TYPE

This will bring back only active values

SELECT  PropertyID,
        TYPE,
        SUM(Amount)
FROM    yourTable
WHERE   EndDate IS NULL
GROUP BY    PropertyID,
            TYPE

and this will bring back totals for properties

SELECT  PropertyID,
        SUM(Amount)
FROM    yourTable
WHERE   EndDate IS NULL
GROUP BY    PropertyID

......

If you install Web Essentials into Visual studio you can go to Edit => Past special => paste JSON as class.

That is probably the easiest there is.

Web Essentials: http://vswebessentials.com/

file_name=test.log

# set first K lines:
K=1000

# line count (N): 
N=$(wc -l < $file_name)

# length of the bottom file:
L=$(( $N - $K ))

# create the top of file: 
head -n $K $file_name > top_$file_name

# create bottom of file: 
tail -n $L $file_name > bottom_$file_name

Also, on second thought, split will work in your case, since the first split is larger than the second. Split puts the balance of the input into the last split, so

split -l 300000 file_name

will output xaa with 300k lines and xab with 100k lines, for an input with 400k lines.

Edit the tty configuration in /etc/init/tty*.conf with a shellscript as a parameter :

(...)
exec /sbin/getty -n -l  theInputScript.sh -8 38400 tty1
(...)

This is assuming that we're editing tty1 and the script that reads input is theInputScript.sh.

A word of warning this script is run as root, so when you are inputing stuff to it you have root priviliges. Also append a path to the location of the script.

Important: the script when it finishes, has to invoke the /sbin/login otherwise you wont be able to login in the terminal.

You don't.

If you want to extend Person with Student, just do:

public class Student extends Person
{
}

And make sure, when you compile both classes, one can find the other one.

What IDE are you using?

It look like the class Algebra5FirstViewController is compile multiple time.

Can you make sure that the .m and .mm is only included once in your project sources in Xcode? You can also confirm this by checking in the compile log (last icon at the right, next to the breakpoints icon) and see that confirm that it is only compiled once.

Also, if this class is part of a library that you link against and you have a class with the same name, you could have the same error.

Finally, you can try a clean and rebuild, just in case the old object files are still present and there is some junk in the compiled files. Just in case...

EDIT

I also note that the second reference is made in the file for ExercisesViewController. Maybe there is something in this file. Either you #imported the Algebra5FirstViewController file instead of the .h, or the ExercisesViewController has @implementation (Algebra5FirstViewController) instead of @implementation (ExercisesViewController), or there was some junk with this file that will cleaned with a Clean an Rebuild.

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

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

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

XPath selection based on text within element.

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

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

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

Simple way to do this. Try this code. Put code in your htaccess file:

Options +FollowSymLinks

RewriteEngine on

RewriteRule profile/(.*)/ profile.php?u=$1

RewriteRule profile/(.*) profile.php?u=$1   

It will create this type pretty URL:

http://www.domain.com/profile/12345/

For some reason ele.onchange() is throwing a "method not found" expception for me in IE on my page, so I ended up using this function from the link Kolten provided and calling fireEvent(ele, 'change'), which worked:

function fireEvent(element,event){
    if (document.createEventObject){
        // dispatch for IE
        var evt = document.createEventObject();
        return element.fireEvent('on'+event,evt)
    }
    else{
        // dispatch for firefox + others
        var evt = document.createEvent("HTMLEvents");
        evt.initEvent(event, true, true ); // event type,bubbling,cancelable
        return !element.dispatchEvent(evt);
    }
}

I did however, create a test page that confirmed calling should onchange() work:

<input id="test1" name="test1" value="Hello" onchange="alert(this.value);"/>
<input type="button" onclick="document.getElementById('test1').onchange();" value="Say Hello"/>

Edit: The reason ele.onchange() didn't work was because I hadn't actually declared anything for the onchange event. But the fireEvent still works.

For me it worked by closing the Eclipse and using the command line to build the project. Seems like Eclipse had taken a lock on the files.

You must specify the full path of the resource file as the name of 'image within the resources of your application, see example below.

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    PictureBox1.Image = My.Resources.Chrysanthemum
End Sub

In the path assigned to the Image property after MyResources specify the name of the resource.

But before you do whatever you have to import in the resource section of your application from an image file exists or it can create your own.

Bye

You can also use Ticks. I'm coding for Windows Mobile so don't have the full set of methods. TotalSeconds is not available to me.

long epochTicks = new DateTime(1970, 1, 1).Ticks;
long unixTime = ((DateTime.UtcNow.Ticks - epochTicks) / TimeSpan.TicksPerSecond);

or

TimeSpan epochTicks = new TimeSpan(new DateTime(1970, 1, 1).Ticks);
TimeSpan unixTicks = new TimeSpan(DateTime.UtcNow.Ticks) - epochTicks;
double unixTime = unixTicks.TotalSeconds;

In my opinion the best approach to achieve this by using the filter method as it's meaningless to return in a forEach block; for an example on your snippet:

// Fetch all objects in SomeElements collection
var elementsCollection = SomeElements.find();
elementsCollection
.filter(function(element) {
  return element.shouldBeProcessed;
})
.forEach(function(element){
  doSomeLengthyOperation();
});

This will narrow down your elementsCollection and just keep the filtred elements that should be processed.

Your problem is most likely with the video file, not the code. Your video is most likely not "safe for streaming". See where to place videos to stream android for more.

1NF: Only one value per column

2NF: All the non primary key columns in the table should depend on the entire primary key.

3NF: All the non primary key columns in the table should depend DIRECTLY on the entire primary key.

OFFLINE SOLUTION - Haversine Algorithm

I had a similar problem with a less complicated formula:

= If (x > A & x <= B) 

and found that I could Remove the AND and join the two comparisons with +

  = (x > A1) + (x <= B1)        [without all the spaces]

Hope this helps others with less complex comparisons.

Check out http://codepad.org. It probably won't solve the poster's problem; but, I think it will be of use to others who read this article.

The simplest way to this is:

<input type="checkbox" class="special" onclick="event.preventDefault();" checked />

This will prevent the user from being able to deselect this checkbox and it will still submit its value when the form is submitted. Remove checked if you want the user to not be able to select this checkbox.

Also, you can then use javascript to clear the onclick once a certain condition has been met (if that's what you're after). Here's a down-and-dirty fiddle showing what I mean. It's not perfect, but you get the gist.

http://jsfiddle.net/vwUUc/

Have you got access to SSH?

You can use this command in shell to backup an entire database:

mysqldump -u [username] -p[password] [databasename] > [filename.sql]

This is actually one command followed by the > operator, which says, "take the output of the previous command and store it in this file."

Note: The lack of a space between -p and the mysql password is not a typo. However, if you leave the -p flag present, but the actual password blank then you will be prompted for your password. Sometimes this is recommended to keep passwords out of your bash history.

The other answers here clearly explained what does it mean.I like to explain its use.

You can select an element in the elements tab and switch to console tab in chrome. Just type $0 or $1 or whatever number and press enter and the element will be displayed in the console for your use.

fastest way is by signing with the debug keystore:

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore ~/.android/debug.keystore app.apk androiddebugkey -storepass android

or on Windows:

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore %USERPROFILE%/.android/debug.keystore test.apk androiddebugkey -storepass android

Add the following to the avd config.ini

disk.dataPartition.size=1024MB

Let me know if this works for you also.

I added in the line

Look here.

Your URL is quite incorrect. Should look like this:

url="jdbc:oracle:thin:@localhost:1521:orcl"

You don't register a driver class, either. You want to download the thin driver JAR, put it in your CLASSPATH, and make your code look more like this.

UPDATE: The "14" in "ojdbc14.jar" stands for JDK 1.4. You should match your driver version with the JDK you're running. I'm betting that means JDK 5 or 6.

You'll need to store the old value manually. You could store it a lot of different ways. You could use a javascript object to store values for each textbox, or you could use a hidden field (I wouldn't recommend it - too html heavy), or you could use an expando property on the textbox itself, like this:

<input type="text" onfocus="this.oldvalue = this.value;" onchange="onChangeTest(this);this.oldvalue = this.value;" />

Then your javascript function to handle the change looks like this:

    <script type="text/javascript">
    function onChangeTest(textbox) {
        alert("Value is " + textbox.value + "\n" + "Old Value is " + textbox.oldvalue);
    }
    </script>

It is changed to : from PIL.Image import core as image for new versions.

If you want to sort data either in Ascending or Descending order based on particular column, using sequlize js, use the order method of sequlize as follows

// Will order the specified column by descending order
order: sequelize.literal('column_name order')
e.g. order: sequelize.literal('timestamp DESC')

From the command line:

psql -f 1.sql
psql -f 2.sql

From the psql prompt:

\i 1.sql
\i 2.sql

Note that you may need to import the files in a specific order (for example: data definition before data manipulation). If you've got bash shell (GNU/Linux, Mac OS X, Cygwin) and the files may be imported in the alphabetical order, you may use this command:

for f in *.sql ; do psql -f $f ; done

Here's the documentation of the psql application (thanks, Frank): http://www.postgresql.org/docs/current/static/app-psql.html
