Just an update to the answer of @rafa.pereira. Since ggplot2 is part of tidyverse, it makes sense to use the convenient tidyverse functions to get rid of NAs.

library(tidyverse)
airquality %>% 
        drop_na(Ozone) %>%
        ggplot(aes(x = Ozone))+
        geom_bar(stat="bin")

Note that you can also use drop_na() without columns specification; then all the rows with NAs in any column will be removed.

When console.log(this.ev) is executed after this.fetchEvent();, this doesn't mean the fetchEvent() call is done, this only means that it is scheduled. When console.log(this.ev) is executed, the call to the server is not even made and of course has not yet returned a value.

Change fetchEvent() to return a Promise

     fetchEvent(){
        return  this._apiService.get.event(this.eventId).then(event => {
            this.ev = event;
            console.log(event); // Has a value
            console.log(this.ev); // Has a value
        });
     }

change ngOnInit() to wait for the Promise to complete

    ngOnInit() {
        this.fetchEvent().then(() =>
        console.log(this.ev)); // Now has value;
    }

This actually won't buy you much for your use case.

My suggestion: Wrap your entire template in an <div *ngIf="isDataAvailable"> (template content) </div>

and in ngOnInit()

    isDataAvailable:boolean = false;

    ngOnInit() {
        this.fetchEvent().then(() =>
        this.isDataAvailable = true); // Now has value;
    }

I use the code I found @.w3resources

The code takes care of

• month being less than 12,

• days being less than 32

• even works with leap years. While Using in my project for leap year I modify the code like

  if ((lyear==false) && (dd>=29))
  {
  alert('Invalid date format!');
  return false;
  }

  if ((lyear==false) && (dd>=29))
  {
  alert('not a Leap year February cannot have more than 28days');
  return false;
  }

Rather than throwing the generic "Invalid date format" error which does not make much sense to the user. I modify the rest of the code to provide valid error message like month cannot be more than 12, days cannot be more than 31 etc.,

The problem with using Regular expression is it is difficult to identify exactly what went wrong. It either gives a True or a false-Without any reason why it failed. We have to write multiple regular expressions to sort this problem.

Basically, tree conflicts arise if there is some restructure in the folder structure on the branch. You need to delete the conflict folder and use svn clean once. Hope this solves your conflict.

If you are open to vtd-xml, which excels at both performance and memory efficiency, below is the code to do what you are looking for...in both XPath and manual navigation... the overall code is much concise and easier to understand ...

import com.ximpleware.*;
public class queryText {
    public static void main(String[] s) throws VTDException{
        VTDGen vg = new VTDGen();
        if (!vg.parseFile("input.xml", true))
            return;
        VTDNav vn = vg.getNav();
        AutoPilot ap = new AutoPilot(vn);
        // first manually navigate
        if(vn.toElement(VTDNav.FC,"tag")){
            int i= vn.getText();
            if (i!=-1){
                System.out.println("text ===>"+vn.toString(i));
            }
            if (vn.toElement(VTDNav.NS,"tag")){
                i=vn.getText();
                System.out.println("text ===>"+vn.toString(i));
            }
        }

        // second version use XPath
        ap.selectXPath("/add/tag/text()");
        int i=0;
        while((i=ap.evalXPath())!= -1){
            System.out.println("text node ====>"+vn.toString(i));
        }
    }
}

A nice addition is the ability to drop columns only if they exist. This way you can cover more use cases, and it will only drop the existing columns from the labels passed to it:

Simply add errors='ignore', for example.:

df.drop(['col_name_1', 'col_name_2', ..., 'col_name_N'], inplace=True, axis=1, errors='ignore')

• This is new from pandas 0.16.1 onward. Documentation is here.

The closest you can get is typeof, but it only returns "object" for any sort of custom type. For those, see Jason Bunting.

Edit, Jason's deleted his post for some reason, so just use Object's constructor property.

This works for me. Load your properties file from current directory.

Attention: The method Properties#load uses ISO-8859-1 encoding.

Properties properties = new Properties();
properties.load(new FileReader(new File(".").getCanonicalPath() + File.separator + "java.properties"));
properties.forEach((k, v) -> {
            System.out.println(k + " : " + v);
        });

Make sure, that java.properties is at the current directory . You can just write a little startup script that switches into to the right directory in before, like

#! /bin/bash
scriptdir="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )" 
cd $scriptdir
java -jar MyExecutable.jar
cd -

In your project just put the java.properties file in your project root, in order to make this code work from your IDE as well.

The solution I've come up with is:

isinstance(y, (np.ndarray, np.generic) )

However, it's not 100% clear that all numpy types are guaranteed to be either np.ndarray or np.generic, and this probably isn't version robust.

This is simply merging. Treat each list as if it were a stack, and continuously pop the smaller of the two stack heads, adding the item to the result list, until one of the stacks is empty. Then add all remaining items to the resulting list.

I would recommend not using onsubmit and instead attaching an event in the script.

var submit = document.getElementById("submitButtonId");
if (submit.addEventListener) {
  submit.addEventListener("click", returnToPreviousPage);
} else {
  submit.attachEvent("onclick", returnToPreviousPage);
}

Then use preventDefault() (or returnValue = false for older browsers).

function returnToPreviousPage (e) {
  e = e || window.event;
  // validation code

  // if invalid
  if (e.preventDefault) {
    e.preventDefault();
  } else {
    e.returnValue = false;
  }
}

on Android the interface is exposed via Libcore.os as a kind of hidden API.

Libcore.os.setenv("VAR", "value", bOverwrite);
Libcore.os.getenv("VAR"));

The Libcore class as well as the interface OS is public. Just the class declaration is missing and need to be shown to the linker. No need to add the classes to the application, but it also does not hurt if it is included.

package libcore.io;

public final class Libcore {
    private Libcore() { }

    public static Os os;
}

package libcore.io;

public interface Os {
    public String getenv(String name);
    public void setenv(String name, String value, boolean overwrite) throws ErrnoException;
}

While Yi Jiang's solution may work, I don't believe abandoning the Google Web Font API is the right answer here. We serve a local jQuery file when it's not properly loaded from the CDN, right?

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>
<script>window.jQuery || document.write('<script src="/js/jquery-1.9.0.min.js"><\/script>')</script>

So why wouldn't we do the same for fonts, specifically for < IE9?

<link href='http://fonts.googleapis.com/css?family=Cardo:400,400italic,700' rel='stylesheet' type='text/css'>
<!--[if lt IE 9]><link href='/css/fonts.css' rel='stylesheet' type='text/css'><![endif]-->

Here's my process when using custom fonts:

1. Download the font's ZIP folder from Google, and use Font Squirrel's @font-face Generator to create the local web font.

2. Create a fonts.css file that calls the newly created, locally hosted font files (only linking to the file if < IE9, as shown above). NOTE: The @font-face Generator creates this file for you.

   @font-face {
     font-family: 'cardoitalic';
     src: url('cardo-italic-webfont.eot');
     src: url('cardo-italic-webfont.eot?#iefix') format('embedded-opentype'),
       url('cardo-italic-webfont.woff') format('woff'),
       url('cardo-italic-webfont.ttf') format('truetype'),
       url('cardo-italic-webfont.svg#cardoitalic') format('svg');
     font-weight: normal;
     font-style: normal;
   }
   @font-face {
     font-family: 'cardobold';
     src: url('cardo-bold-webfont.eot');
     src: url('cardo-bold-webfont.eot?#iefix') format('embedded-opentype'),
       url('cardo-bold-webfont.woff') format('woff'),
       url('cardo-bold-webfont.ttf') format('truetype'),
       url('cardo-bold-webfont.svg#cardobold') format('svg');
     font-weight: normal;
     font-style: normal;
   }
   @font-face {
     font-family: 'cardoregular';
     src: url('cardo-regular-webfont.eot');
     src: url('cardo-regular-webfont.eot?#iefix') format('embedded-opentype'),
        url('cardo-regular-webfont.woff') format('woff'),
        url('cardo-regular-webfont.ttf') format('truetype'),
        url('cardo-regular-webfont.svg#cardoregular') format('svg');
     font-weight: normal;
     font-style: normal;
   }
   

3. Using IE conditional classes in your main stylesheet to avoide faux weights and styles, your font styles might look like this:

   h1{
     font-size:3.25em;
     font-weight:normal;
     font-style:italic;
     font-family:'Cardo','cardoitalic',serif;
     line-height:1.25em;
   }
   h2{
     font-size:2.75em;
     font-weight:700;
     font-family:'Cardo','cardobold',serif;
     line-height:1.25em;
   }
   strong
   ,b{
     font-family:'Cardo','cardobold',serif;
     font-weight:700,
   }
   .lt-ie9 h1{
     font-style:normal;
   }
   .lt-ie9 h2{
     font-weight:normal;
   }
   .lt-ie9 strong,
   .lt-ie9 b{
     font-weight:normal,
   }
   

Sure, it's a little extra work, but haven't we come to expect this from IE? Besides, it becomes second-nature after awhile.

Another possible solution specially if you want batch delete

deleted_objects = User.__table__.delete().where(User.id.in_([1, 2, 3]))
session.execute(deleted_objects)
session.commit()

In a comment to one of the answers you mention that to_date with a format doesn't help. In another comment you explain that the table is accessed via DBLINK.

So obviously the other system contains an invalid date that Oracle cannot accept. Fix this in the other dbms (or whatever you dblink to) and your query will work.

Having said this, I agree with the others: always use to_date with a format to convert a string literal to a date. Also never use only two digits for a year. For example '23/04/49' means 2049 in your system (format RR), but it confuses the reader (as you see from the answers suggesting a format with YY).

It's for the same reason you don't write every method of every class to return "object". You should be as specific as you can. This is especially valuable if you're planning to write unit tests. No more testing return types and/or casting the result.

yes, but only if main is declared public

When I tried your code, it worked.

The only reason that your event is not working, may be that your DOM was not ready and your button with id "event-btn" was not yet ready. And your javascript got executed and tried to bind the event with that element.

Before using the DOM element for binding, that element should be ready. There are many options to do that.

Option1: You can move your event binding code within document ready event. Like:

document.addEventListener('DOMContentLoaded', (event) => {
  //your code to bind the event
});

Option2: You can use timeout event, so that binding is delayed for few seconds. like:

setTimeout(function(){
  //your code to bind the event
}, 500);

Option3: move your javascript include to the bottom of your page.

I hope this helps you.

I got same error because I was trying to run on

In TortoiseSVN you can configure the proxy server under Settings=> Network

In my experience, first name/last name fields should be at least 48 characters -- there are names from some countries such as Malaysia or India that are very long in their full form.

Phone numbers and postcodes you should always treat as text, not numbers. The normal reason given is that there are postcodes that begin with 0, and in some countries, phone numbers can also begin with 0. But the real reason is that they aren't numbers -- they're identifiers that happen to be made up of numerical digits (and that's ignoring countries like Canada that have letters in their postcodes). So store them in a text field.

In MySQL you can use VARCHAR fields for this type of information. Whilst it sounds lazy, it means you don't have to be too concerned about the right minimum size.

I would exploit the retransmission behaviour of TCP.

1. Make the TCP component create a large receive window.
2. Receive some amount of packets without sending an ACK for them.
   • Process those in passes creating some (prefix) compressed data structure
   • Send duplicate ack for last packet that is not needed anymore/wait for retransmission timeout
   • Goto 2
3. All packets were accepted

This assumes some kind of benefit of buckets or multiple passes.

Probably by sorting the batches/buckets and merging them. -> radix trees

Use this technique to accept and sort the first 80% then read the last 20%, verify that the last 20% do not contain numbers that would land in the first 20% of the lowest numbers. Then send the 20% lowest numbers, remove from memory, accept the remaining 20% of new numbers and merge.**

Checking for the length of the string also works and is compact:

Most of the answers in this thread are using plain vim commands which is of course fine but I thought I would provide an extensive answer using a combination of plugins and functions that I find particularly useful (at least some of these tips came from Gary Bernhardt's file navigation tips):

1. To toggle between the last two file just press <leader> twice. I recommend assigning <leader> to the spacebar:

   nnoremap <leader><leader> <c-^>
   

2. For quickly moving around a project the answer is a fuzzy matching solution such as CtrlP. I bind it to <leader>a for quick access.

3. In the case I want to see a visual representation of the currently open buffers I use the BufExplorer plugin. Simple but effective.

4. If I want to browse around the file system I would use the command line or an external utility (Quicklsilver, Afred etc.) but to look at the current project structure NERD Tree is a classic. Do not use this though in the place of 2 as your main file finding method. It will really slow you down. I use the binding <leader>ff.

These should be enough for finding and opening files. From there of course use horizontal and vertical splits. Concerning splits I find these functions particularly useful:

1. Open new splits in smaller areas when there is not enough room and expand them on navigation. Refer here for comments on what these do exactly:

   set winwidth=84
   set winheight=5
   set winminheight=5
   set winheight=999
   
   nnoremap <C-w>v :111vs<CR>
   nnoremap <C-w>s :rightbelow split<CR>
   set splitright
   

2. Move from split to split easily:

   nnoremap <C-J> <C-W><C-J>
   nnoremap <C-K> <C-W><C-K>
   nnoremap <C-L> <C-W><C-L>
   nnoremap <C-H> <C-W><C-H>
   

Clean and simple JSfiddle

This will be useful when you want The event to triggered indirectly from a div or a button.

<img id="image-preview"  style="height:100px; width:100px;"  src="" >

<input style="display:none" id="input-image-hidden" onchange="document.getElementById('image-preview').src = window.URL.createObjectURL(this.files[0])" type="file" accept="image/jpeg, image/png">

<button  onclick="HandleBrowseClick('input-image-hidden');" >UPLOAD IMAGE</button>


<script type="text/javascript">
function HandleBrowseClick(hidden_input_image)
{
    var fileinputElement = document.getElementById(hidden_input_image);
    fileinputElement.click();
}     
</script>

There are several problems in your code.

First the big ones:

1. You are creating a new figure and a new axes in every iteration of your loop ? put fig = plt.figure and ax = fig.add_subplot(1,1,1) outside of the loop.

2. Don't use the Locators. Call the functions ax.set_xticks() and ax.grid() with the correct keywords.

3. With plt.axes() you are creating a new axes again. Use ax.set_aspect('equal').

The minor things: You should not mix the MATLAB-like syntax like plt.axis() with the objective syntax. Use ax.set_xlim(a,b) and ax.set_ylim(a,b)

This should be a working minimal example:

import numpy as np
import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(1, 1, 1)

# Major ticks every 20, minor ticks every 5
major_ticks = np.arange(0, 101, 20)
minor_ticks = np.arange(0, 101, 5)

ax.set_xticks(major_ticks)
ax.set_xticks(minor_ticks, minor=True)
ax.set_yticks(major_ticks)
ax.set_yticks(minor_ticks, minor=True)

# And a corresponding grid
ax.grid(which='both')

# Or if you want different settings for the grids:
ax.grid(which='minor', alpha=0.2)
ax.grid(which='major', alpha=0.5)

plt.show()

Output is this:

Your makefile should ideally be named makefile, not make. Note that you can call your makefile anything you like, but as you found, you then need the -f option with make to specify the name of the makefile. Using the default name of makefile just makes life easier.

Basing my answer on assumption that user just wanted to literaaly convert an int to char , for example

Input: 
int i = 5; 
Output:
char c = '5'

This has been already answered above, however if the integer value i > 10, then need to use char array.

char[] c = String.valueOf(i).toCharArray();

You need two tables, where the first one is an exact overlay over the second one. The second one contains all the data, where the first one just contains the first column. You have to synchronize it's width and depending on the content also the height of it's rows.

Additional to this two tables, you need a third one. That's the first row, which lays exactly between the other two and has to be synchronized in the same way.

You will need absolute positioning here. Next, you would synchronize the scrolling of the data table with the scrolling positions of the head row and first column table.

That works very well in all major browsers, except for one issue: The synchronized scrolling will flutter. To fix that, you need two outher div containers that hold a clone of the content of the header row and the first column. When scrolling vertically, you display the header row clone to prevent fluttering, while you reposition the original in the background. When scrolling horizontally, you would show the first row clone. Same thing here.

It's really hard to tell, but one of the 9001 ads on the page may be clobbering the $ object.

jQuery provides the global jQuery object (which is present on your page). You can do the following to "get" $ back:

jQuery(document).ready(function ($) {
    // Your code here
});

If you think you're having jQuery problems, please use the debug (non-production) versions of the library.

Also, it's probably not best to be editing a live site like that ...

I got the same error when I check the localhost is set in hosts file it is somehow not set. Setting localhost to 127.0.0.1 solved it.

sudo vi /etc/hosts
>>

127.0.0.1       localhost

As documented in Working with text data:

df.columns = df.columns.str.replace('$', '')

Update: there are two possible scenarios here:

1. You are determining if an object is a collection;

2. You are determining if a class is a collection.

The solutions are slightly different but the principles are the same. You also need to define what exactly constitutes a "collection". Implementing either Collection or Map will cover the Java Collections.

Solution 1:

public static boolean isCollection(Object ob) {
  return ob instanceof Collection || ob instanceof Map;
}

Solution 2:

public static boolean isClassCollection(Class c) {
  return Collection.class.isAssignableFrom(c) || Map.class.isAssignableFrom(c);
}

(1) can also be implemented in terms of (2):

public static boolean isCollection(Object ob) {
  return ob != null && isClassCollection(ob.getClass());
}

I don't think the efficiency of either method will be greatly different from the other.

with laravel pagination

file.component.ts file

    datasource: any = {
        data: []
    }

    loadData() {
        this.service.find(this.params).subscribe((res: any) => {
            this.datasource = res;
        });
    }

html file

   <tr *ngFor="let item of datasource.data; let i = index">
       <th>{{ datasource.from + i }}</th>
   </tr>

Remember that each Add will check the capacity of the collection and resize it whenever necessary (slower). With AddRange, the collection will be set the capacity and then added the items (faster). This extension method will be extremely slow, but will work.

If you really want to split every word (bash meaning) into a different array index completely changing the array in every while loop iteration, @ruakh's answer is the correct approach. But you can use the read property to split every read word into different variables column1, column2, column3 like in this code snippet

while IFS=$'\t' read -r column1 column2 column3 ; do
  printf "%b\n" "column1<${column1}>"
  printf "%b\n" "column2<${column2}>"
  printf "%b\n" "column3<${column3}>"
done < "myfile"

to reach a similar result avoiding array index access and improving your code readability by using meaningful variable names (of course using columnN is not a good idea to do so).

I used the property

display: table;

and

display: table-cell;

to achieve the same.Link to fiddle below shows 3 tables wrapped in divs and these divs are further wrapped in a parent div

<div id='content'>
   <div id='div-1'><!-- COntains table --></div>
   <div id='div-2'><!-- contains two more divs that require to be arranged one below other --></div>
</div>

One more related question, since it took me forever to find the answer:

How to make the legend background blank (i.e. transparent, not white):

legend = plt.legend()
legend.get_frame().set_facecolor('none')

Warning, you want 'none' (the string). None means the default color instead.

Just want to add this for the future programmer.

This code limits the date min and max. The year is fully controlled by getting the current year as max year.

Hope this could help to anyone.

Here's the code.

var dateToday = new Date();
var yrRange = '2014' + ":" + (dateToday.getFullYear());

$(function () {
    $("[id$=txtDate]").datepicker({
        showOn: 'button',
        changeMonth: true,
        changeYear: true,
        showButtonPanel: true,
        buttonImageOnly: true,
        yearRange: yrRange,
        buttonImage: 'calendar3.png',
        buttonImageOnly: true,
        minDate: new Date(2014,1-1,1),
        maxDate: '+50Y',

1) JTable knows JCheckbox with built-in Boolean TableCellRenderers and TableCellEditor by default, then there is contraproductive declare something about that,

2) AbstractTableModel should be useful, where is in the JTable required to reduce/restrict/change nested and inherits methods by default implemented in the DefaultTableModel,

3) consider using DefaultTableModel, (if you are not sure about how to works) instead of AbstractTableModel,

could be generated from simple code:

import javax.swing.table.*;

    private static final long serialVersionUID = 1L;

Apache HttpComponents. The examples for the two modules - HttpCore and HttpClient will get you started right away.

Not that HttpUrlConnection is a bad choice, HttpComponents will abstract a lot of the tedious coding away. I would recommend this, if you really want to support a lot of HTTP servers/clients with minimum code. By the way, HttpCore could be used for applications (clients or servers) with minimum functionality, whereas HttpClient is to be used for clients that require support for multiple authentication schemes, cookie support etc.

If I understand you correctly, you want to compose a multipart request manually from an HTTP/REST console. The multipart format is simple; a brief introduction can be found in the HTML 4.01 spec. You need to come up with a boundary, which is a string not found in the content, let’s say HereGoes. You set request header Content-Type: multipart/form-data; boundary=HereGoes. Then this should be a valid request body:

--HereGoes
Content-Disposition: form-data; name="myJsonString"
Content-Type: application/json

{"foo": "bar"}
--HereGoes
Content-Disposition: form-data; name="photo"
Content-Type: image/jpeg
Content-Transfer-Encoding: base64

<...JPEG content in base64...>
--HereGoes--

In command line it's better to use REG tool rather than REGEDIT:

REG IMPORT yourfile.reg

REG is designed for console mode, while REGEDIT is for graphical mode. This is why running regedit.exe /S yourfile.reg is a bad idea, since you will not be notified if the there's an error, whereas REG Tool will prompt:

>  REG IMPORT missing_file.reg

ERROR: Error opening the file. There may be a disk or file system error.

>  %windir%\System32\reg.exe /?

There are two widely-used memory allocation techniques: automatic allocation and dynamic allocation. Commonly, there is a corresponding region of memory for each: the stack and the heap.

Stack

The stack always allocates memory in a sequential fashion. It can do so because it requires you to release the memory in the reverse order (First-In, Last-Out: FILO). This is the memory allocation technique for local variables in many programming languages. It is very, very fast because it requires minimal bookkeeping and the next address to allocate is implicit.

In C++, this is called automatic storage because the storage is claimed automatically at the end of scope. As soon as execution of current code block (delimited using {}) is completed, memory for all variables in that block is automatically collected. This is also the moment where destructors are invoked to clean up resources.

Heap

The heap allows for a more flexible memory allocation mode. Bookkeeping is more complex and allocation is slower. Because there is no implicit release point, you must release the memory manually, using delete or delete[] (free in C). However, the absence of an implicit release point is the key to the heap's flexibility.

Reasons to use dynamic allocation

Even if using the heap is slower and potentially leads to memory leaks or memory fragmentation, there are perfectly good use cases for dynamic allocation, as it's less limited.

Two key reasons to use dynamic allocation:

• You don't know how much memory you need at compile time. For instance, when reading a text file into a string, you usually don't know what size the file has, so you can't decide how much memory to allocate until you run the program.

• You want to allocate memory which will persist after leaving the current block. For instance, you may want to write a function string readfile(string path) that returns the contents of a file. In this case, even if the stack could hold the entire file contents, you could not return from a function and keep the allocated memory block.

Why dynamic allocation is often unnecessary

In C++ there's a neat construct called a destructor. This mechanism allows you to manage resources by aligning the lifetime of the resource with the lifetime of a variable. This technique is called RAII and is the distinguishing point of C++. It "wraps" resources into objects. std::string is a perfect example. This snippet:

int main ( int argc, char* argv[] )
{
    std::string program(argv[0]);
}

actually allocates a variable amount of memory. The std::string object allocates memory using the heap and releases it in its destructor. In this case, you did not need to manually manage any resources and still got the benefits of dynamic memory allocation.

In particular, it implies that in this snippet:

int main ( int argc, char* argv[] )
{
    std::string * program = new std::string(argv[0]);  // Bad!
    delete program;
}

there is unneeded dynamic memory allocation. The program requires more typing (!) and introduces the risk of forgetting to deallocate the memory. It does this with no apparent benefit.

Why you should use automatic storage as often as possible

Basically, the last paragraph sums it up. Using automatic storage as often as possible makes your programs:

• faster to type;
• faster when run;
• less prone to memory/resource leaks.

Bonus points

In the referenced question, there are additional concerns. In particular, the following class:

class Line {
public:
    Line();
    ~Line();
    std::string* mString;
};

Line::Line() {
    mString = new std::string("foo_bar");
}

Line::~Line() {
    delete mString;
}

Is actually a lot more risky to use than the following one:

class Line {
public:
    Line();
    std::string mString;
};

Line::Line() {
    mString = "foo_bar";
    // note: there is a cleaner way to write this.
}

The reason is that std::string properly defines a copy constructor. Consider the following program:

int main ()
{
    Line l1;
    Line l2 = l1;
}

Using the original version, this program will likely crash, as it uses delete on the same string twice. Using the modified version, each Line instance will own its own string instance, each with its own memory and both will be released at the end of the program.

Other notes

Extensive use of RAII is considered a best practice in C++ because of all the reasons above. However, there is an additional benefit which is not immediately obvious. Basically, it's better than the sum of its parts. The whole mechanism composes. It scales.

If you use the Line class as a building block:

 class Table
 {
      Line borders[4];
 };

Then

 int main ()
 {
     Table table;
 }

allocates four std::string instances, four Line instances, one Table instance and all the string's contents and everything is freed automagically.

Another and simple way

ORDER BY ABS(column_name)

A basic implementation which you'll need to adapt would look something like this:

function insertParam(key, value) {
    key = encodeURIComponent(key);
    value = encodeURIComponent(value);

    // kvp looks like ['key1=value1', 'key2=value2', ...]
    var kvp = document.location.search.substr(1).split('&');
    let i=0;

    for(; i<kvp.length; i++){
        if (kvp[i].startsWith(key + '=')) {
            let pair = kvp[i].split('=');
            pair[1] = value;
            kvp[i] = pair.join('=');
            break;
        }
    }

    if(i >= kvp.length){
        kvp[kvp.length] = [key,value].join('=');
    }

    // can return this or...
    let params = kvp.join('&');

    // reload page with new params
    document.location.search = params;
}

This is approximately twice as fast as a regex or search based solution, but that depends completely on the length of the querystring and the index of any match

the slow regex method I benchmarked against for completions sake (approx +150% slower)

function insertParam2(key,value)
{
    key = encodeURIComponent(key); value = encodeURIComponent(value);

    var s = document.location.search;
    var kvp = key+"="+value;

    var r = new RegExp("(&|\\?)"+key+"=[^\&]*");

    s = s.replace(r,"$1"+kvp);

    if(!RegExp.$1) {s += (s.length>0 ? '&' : '?') + kvp;};

    //again, do what you will here
    document.location.search = s;
}

Then if you want to go into more fully-fledged stuff, thankfully the need for automated web-testing as given us very practical tools for this. Look at:

• HtmlUnit (powerful and simple)
• Selenium, Selenium-RC
• WebDriver/Selenium2 (still in the works)
• JBehave with JBehave Web

Some other libs are purposefully written with web-scraping in mind:

• JSoup
• Jaunt

Some Workarounds

Java is a language, but also a platform, with many other languages running on it. Some of which integrate great syntactic sugar or libraries to easily build scrapers.

Check out:

• Groovy (and its XmlSlurper)
• or Scala (with great XML support as presented here and here)

If you know of a great library for Ruby (JRuby, with an article on scraping with JRuby and HtmlUnit) or Python (Jython) or you prefer these languages, then give their JVM ports a chance.

I had this message too because today i decided to relocate my different jdk in the same directory. I have decided to uninstall all through program manager of window. After that, of course i had the message below.

"Cannot locate java installation in specified jdkhome C:\Program Files (x86)\Java\jdk1.7.0_60 Do you want to try to use default version ?"

A new install of the jdk does not resolve the problem. Ok you can configure that in menu Tool > java platforms but in my case i had to fix my netbeans.conf

i had the line below

netbeans_jdkhome="C:\Program Files\Java\jdk1.7.0_60"

and i replace it by

netbeans_jdkhome="C:\devtools\Java\jdk1.8.0_25"

Uploading files is actually possible with AJAX these days. Yes, AJAX, not some crappy AJAX wannabes like swf or java.

This example might help you out: https://webblocks.nl/tests/ajax/file-drag-drop.html

(It also includes the drag/drop interface but that's easily ignored.)

Basically what it comes down to is this:

<input id="files" type="file" />

<script>
document.getElementById('files').addEventListener('change', function(e) {
    var file = this.files[0];
    var xhr = new XMLHttpRequest();
    (xhr.upload || xhr).addEventListener('progress', function(e) {
        var done = e.position || e.loaded
        var total = e.totalSize || e.total;
        console.log('xhr progress: ' + Math.round(done/total*100) + '%');
    });
    xhr.addEventListener('load', function(e) {
        console.log('xhr upload complete', e, this.responseText);
    });
    xhr.open('post', '/URL-HERE', true);
    xhr.send(file);
});
</script>

(demo: http://jsfiddle.net/rudiedirkx/jzxmro8r/)

So basically what it comes down to is this =)

xhr.send(file);

Where file is typeof Blob: http://www.w3.org/TR/FileAPI/

Another (better IMO) way is to use FormData. This allows you to 1) name a file, like in a form and 2) send other stuff (files too), like in a form.

var fd = new FormData;
fd.append('photo1', file);
fd.append('photo2', file2);
fd.append('other_data', 'foo bar');
xhr.send(fd);

FormData makes the server code cleaner and more backward compatible (since the request now has the exact same format as normal forms).

All of it is not experimental, but very modern. Chrome 8+ and Firefox 4+ know what to do, but I don't know about any others.

This is how I handled the request (1 image per request) in PHP:

if ( isset($_FILES['file']) ) {
    $filename = basename($_FILES['file']['name']);
    $error = true;

    // Only upload if on my home win dev machine
    if ( isset($_SERVER['WINDIR']) ) {
        $path = 'uploads/'.$filename;
        $error = !move_uploaded_file($_FILES['file']['tmp_name'], $path);
    }

    $rsp = array(
        'error' => $error, // Used in JS
        'filename' => $filename,
        'filepath' => '/tests/uploads/' . $filename, // Web accessible
    );
    echo json_encode($rsp);
    exit;
}

Using Guava library:

int size = Iterators.size(iterator);

Internally it just iterates over all elements so its just for convenience.

if it is a new repo you've cloned, it may still be empty, in which case:

git push -u origin master

should likely sort it out.

(did in my case. not sure this is the same issue, thought i should post this just incase. might help others.)

I'd prefer to normalize your table structure more, something like;

COMMENTS
-------
id (pk)
title
comment
userId


USERS
-----
id (pk)
name
email


COMMENT_VOTE
------------
commentId (pk)
userId (pk)
rating (float)

Now it's easier to maintain! And MySQL only accept one vote per user and comment.

For Netbeans 11 users, this works for me:

apply plugin: 'java'
apply plugin: 'application'

// This comes out to package + '.' + mainClassName
mainClassName = 'com.hello.JavaApplication1'

Here generally is my tree:

C:\...\NETBEANSPROJECTS\JAVAAPPLICATION1
¦   build.gradle
+---src
¦   +---main
¦   ¦   +---java
¦   ¦       +---com
¦   ¦           +---hello
¦   ¦                   JavaApplication1.java
¦   ¦
¦   +---test
¦       +---java
+---test

The && function is not vectorized. You need the & function:

EUR <- PCs[which(PCs$V13 < 9 & PCs$V13 > 3), ]

In Ubuntu 18.04, this error has a different cause (JEP 229, switch from the jks keystore default format to the pkcs12 format, and the Debian cacerts file generation using the default for new files) and workaround:

# Ubuntu 18.04 and various Docker images such as openjdk:9-jdk throw exceptions when
# Java applications use SSL and HTTPS, because Java 9 changed a file format, if you
# create that file from scratch, like Debian / Ubuntu do.
#
# Before applying, run your application with the Java command line parameter
#  java -Djavax.net.ssl.trustStorePassword=changeit ...
# to verify that this workaround is relevant to your particular issue.
#
# The parameter by itself can be used as a workaround, as well.

# 0. First make yourself root with 'sudo bash'.

# 1. Save an empty JKS file with the default 'changeit' password for Java cacerts.
#    Use 'printf' instead of 'echo' for Dockerfile RUN compatibility.

Status (2018-08-07), the bug has been fixed in Ubuntu Bionic LTS 18.04.1 and Ubuntu Cosmic 18.10.

If the issue continues after this workaround, you might want to make sure that you're actually running the Java distribution you just fixed.

$ which java
/usr/bin/java

You can set the Java alternatives to 'auto' with:

$ sudo update-java-alternatives -a
update-alternatives: error: no alternatives for mozilla-javaplugin.so

You can double-check the Java version you're executing:

$ java --version
openjdk 10.0.1 2018-04-17
OpenJDK Runtime Environment (build 10.0.1+10-Ubuntu-3ubuntu1)
OpenJDK 64-Bit Server VM (build 10.0.1+10-Ubuntu-3ubuntu1, mixed mode)

There are alternative workarounds as well, but those have their own side effects which will require extra future maintenance, for no payoff whatsoever.

The next-best workaround is to add the row

javax.net.ssl.trustStorePassword=changeit

to the files

/etc/java-9-openjdk/management/management.properties
/etc/java-11-openjdk/management/management.properties

whichever exists.

The third least problematic workaround is to change the value of

keystore.type=pkcs12

to

keystore.type=jks

in the files

/etc/java-9-openjdk/security/java.security
/etc/java-11-openjdk/security/java.security

whichever exists, and then remove the cacerts file and regenerate it in the manner described on the last row of the workaround script at the top of the post.

All the answers here didn't work (completely) for me. Just to recap what we wanna do for a complete answer: We have a ScrollView, supposedly filling the device's viewport, thus we set fillViewport to "true" in the layout xml. Then, inside the ScrollView, we have a LinearLayout containing everything else, and that LinearLayout should be at least as high as its parent ScrollView, so stuff that's supposed to be on the bottom (of the LinearLayout) is actually, as we want it, at the bottom of the screen (or at the bottom of the ScrollView, in case the LinearLayout's content has more hight than the screen.

Example activity_main.xml layout:

<ScrollView
    android:id="@+id/layout_scrollwrapper"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:fillViewport="true"
    android:layout_alignParentTop="true"
    android:layout_above="@+id/layout_footer"
    >
<LinearLayout
    android:id="@+id/layout_scrollwrapper_inner"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    >
...content which might or might not be higher than screen height...
</LinearLayout>
</ScrollView>

Then, in the activity's onCreate, we "wait" for the LinearLayout's layouting to be done (implying it's parent's layouting is also already done) and then set it's minimum height to the ScrollView's height. Thus it also works in case the ScrollView does not occupy the whole screen height. Whether you call .post(...) on the ScrollView or the inner LinearLayout should not make that much of a difference, if one doesn't work for you, try the other.

public class MainActivity extends AppCompatActivity {

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

    LinearLayout linearLayoutWrapper = findViewById(R.id.layout_scrollwrapper_inner);

    ...

    linearLayoutWrapper.post(() -> {
        linearLayoutWrapper.setMinimumHeight(((ScrollView)linearLayoutWrapper.getParent()).getHeight());
    });
}
...
}

Sadly, it's not an xml-only solution, but it works well enough for me, hope it also helps some other tortured android dev scouring the interwebs in search for a solution to this problem ;D

If you have an Error object already, and you want to print the whole thing, you need to make this slightly awkward call:

import traceback
traceback.print_exception(type(err), err, err.__traceback__)

That's right, print_exception takes three positional arguments: The type of the exception, the actual exception object, and the exception's own internal traceback property.

In python 3.5 or later, the type(err) is optional... but it's a positional argument, so you still have to explicitly pass None in its place.

traceback.print_exception(None, err, err.__traceback__)

I have no idea why all of this isn't just traceback.print_exception(err). Why you would ever want to print out an error, along with a traceback other than the one that belongs to that error, is beyond me.

The new versions of jQuery require this file http://code.jquery.com/jquery-1.10.2.min.map

The usability of this file is described here http://www.html5rocks.com/en/tutorials/developertools/sourcemaps/

Update:

jQuery 1.11.0/2.1.0

// sourceMappingURL comment is not included in the compressed file.

The query either returned no rows or is erroneus, thus FALSE is returned. Change it to

if (!$dbc || mysqli_num_rows($dbc) == 0)

mysqli_num_rows:

Return Values

Returns TRUE on success or FALSE on failure. For SELECT, SHOW, DESCRIBE or EXPLAIN mysqli_query() will return a result object.

There is still another way to do it, which is using a particular NamingStrategy, which can be applied to a class or a property by decorating them with [JSonObject] or [JsonProperty].

There are predefined naming strategies like CamelCaseNamingStrategy, but you can implement your own ones.

The implementation of different naming strategies can be found here: https://github.com/JamesNK/Newtonsoft.Json/tree/master/Src/Newtonsoft.Json/Serialization

You can specify '-m32' or '-m64' to select the compilation mode.

When dealing with autoconf (configure) scripts, I usually set CC="gcc -m64" (or CC="gcc -m32") in the environment so that everything is compiled with the correct bittiness. At least, usually...people find endless ways to make that not quite work, but my batting average is very high (way over 95%) with it.

It is indeed

language: {
 url: '//URL_TO_CDN'
}

The problem is not all of the DataTables (As of this writing) are valid JSON. The Traditional Chinese file for instance is one of them.

To get around this I wrote the following code in JavaScript:

  var dataTableLanguages = {
    'es': '//cdn.datatables.net/plug-ins/1.10.21/i18n/Spanish.json',
    'fr': '//cdn.datatables.net/plug-ins/1.10.21/i18n/French.json',
    'ar': '//cdn.datatables.net/plug-ins/1.10.21/i18n/Arabic.json',
    'zh-TW': {
      "processing": "???...",
      "loadingRecords": "???...",
      "lengthMenu": "?? _MENU_ ???",
      "zeroRecords": "???????",
      "info": "??? _START_ ? _END_ ???,? _TOTAL_ ?",
      "infoEmpty": "??? 0 ? 0 ???,? 0 ?",
      "infoFiltered": "(? _MAX_ ??????)",
      "infoPostFix": "",
      "search": "??:",
      "paginate": {
        "first": "???",
        "previous": "???",
        "next": "???",
        "last": "????"
      },
      "aria": {
        "sortAscending": ": ????",
        "sortDescending": ": ????"
      }
    }
  };
  var language = dataTableLanguages[$('html').attr('lang')];

  var opts = {...};
  
  if (language) {
    if (typeof language === 'string') {
       opts.language = {
         url: language
       };
    } else {
       opts.language = language;
    }
  }

Now use the opts as option object for data table like

$('#list-table').DataTable(opts)

You can also get the page count using

$im->getNumberImages();

Then you can can create thumbs of all the pages using a loop, eg.

'file.pdf['.$x.']'

setInterval(function()
{ 
    $.ajax({
      type:"post",
      url:"myurl.html",
      datatype:"html",
      success:function(data)
      {
          //do something with response data
      }
    });
}, 10000);//time in milliseconds 

I believe the approach:

1. First request, client sends id/passcode
2. Exchange id/pass for unique token
3. Validate token on each subsequent request until it expires

is pretty standard, regardless of how you implement and other specific technical details.

If you really want to push the envelope, perhaps you could regard the client's https key in a temporarily invalid state until the credentials are validated, limit information if they never are, and grant access when they are validated, based again on expiration.

Hope this helps

You can see formControlName in label , removing this solved my problem

Yes, that's possible for instance in this answer I sort by the property v of the class IndexValue

    // Sorting by property v using a custom comparator.
    Arrays.sort( array, new Comparator<IndexValue>(){
        public int compare( IndexValue a, IndexValue b ){
            return a.v - b.v;
        }
    });

If you notice here I'm creating a anonymous inner class ( which is the Java for closures ) and passing it directly to the sort method of the class Arrays

Your object may also implement Comparable ( that's what String and most of the core libraries in Java does ) but that would define the "natural sort order" of the class it self, and doesn't let you plug new ones.

I'm using Eclipse with Cygwin and this worked for me:

Go to Project > Properties > C/C++ General > Preprocessor Includes... > Providers and select "CDT GCC Built-in Compiler Settings Cygwin [Shared]".

So the way I got around this was in the command where i would normally run npm install or npm ci, i added NODE_ENV=build, and then NODE_ENV=production after the command, so my entire command came out to:

RUN NODE_ENV=build && npm ci && NODE_ENV=production

So far I haven't had any bad reactions, and my development dependencies which are used for building the application all worked / loaded correctly.

I find this to be a better solution than adding an additional command like npm install --only=dev because it takes less time, and enables me to use the npm ci command, which is faster and specifically designed to be run inside CI tools / build scripts. (See npi-ci documentation for more information on it)

For windows authentication

select your project.

Press F4

Disable "Anonymous Authentication" and enable "Windows Authentication"

Do configure --help and see what other options are available.

It is very common to provide different options to override different locations. By standard, --prefix overrides all of them, so you need to override config location after specifying the prefix. This course of actions usually works for every automake-based project.

The worse case scenario is when you need to modify the configure script, or even worse, generated makefiles and config.h headers. But yeah, for Xfce you can try something like this:

./configure --prefix=/home/me/somefolder/mybuild/output/target --sysconfdir=/etc 

I believe that should do it.

Any other places you use TimerEventProcessor or Counter?

Anyway, you can not rely on the Event being exactly delivered one per second. The time may vary, and the system will not make sure the average time is correct.

So instead of _Counter, you should use:

 // when starting the timer:
 DateTime _started = DateTime.UtcNow;

 // in TimerEventProcessor:
 seconds = (DateTime.UtcNow-started).TotalSeconds;
 Label.Text = seconds.ToString();

Note: this does not solve the Problem of TimerEventProcessor being called to often, or _Counter incremented to often. it merely masks it, but it is also the right way to do it.

If you have Login in a seperate folder within your project make sure that where you are using it you do:

using FootballLeagueSystem.[Whatever folder you are using]

In the CMakeLists.txt file, create a cache variable, as documented here:

SET(FAB "po" CACHE STRING "Some user-specified option")

Source: http://cmake.org/cmake/help/v2.8.8/cmake.html#command:set

Then, either use the GUI (ccmake or cmake-gui) to set the cache variable, or specify the value of the variable on the cmake command line:

cmake -DFAB:STRING=po

Source: http://cmake.org/cmake/help/v2.8.8/cmake.html#opt:-Dvar:typevalue

Modify your cache variable to a boolean if, in fact, your option is boolean.

The following is works best in my opinion:

Get-Item Env:PATH

1. It's shorter and therefore a little bit easier to remember than Get-ChildItem. There's no hierarchy with environment variables.
2. The command is symmetrical to one of the ways that's used for setting environment variables with Powershell. (EX: Set-Item -Path env:SomeVariable -Value "Some Value")
3. If you get in the habit of doing it this way you'll remember how to list all Environment variables; simply omit the entry portion. (EX: Get-Item Env:)

I found the syntax odd at first, but things started making more sense after I understood the notion of Providers. Essentially PowerShell let's you navigate disparate components of the system in a way that's analogous to a file system.

What's the point of the trailing colon in Env:? Try listing all of the "drives" available through Providers like this:

PS> Get-PSDrive

I only see a few results... (Alias, C, Cert, D, Env, Function, HKCU, HKLM, Variable, WSMan). It becomes obvious that Env is simply another "drive" and the colon is a familiar syntax to anyone who's worked in Windows.

You can navigate the drives and pick out specific values:

Get-ChildItem C:\Windows
Get-Item C:
Get-Item Env:
Get-Item HKLM:
Get-ChildItem HKLM:SYSTEM

ipconfig.exe is implemented using various DLLs including iphlpapi.dll ... Googling for iphlpapi reveals a corresponding Win32 API documented in MSDN.

Finally I found A good css that works!!! Without position: absolute;.

body {

}

I have been looking for this for a long time! Hope this helps.

1. Express.js is a modular web framework for Node.js
2. It is used for easier creation of web applications and services
3. Express.js simplifies development and makes it easier to write secure, modular and fast applications. You can do all that in plain old Node.js, but some bugs can (and will) surface, including security concerns (eg. not escaping a string properly)
4. Redis is an in-memory database system known for its fast performance. No, but you can use it with Express.js using a redis client

I couldn't be more concise than this. For all your other needs and information, Google is your friend.

I have faced the same problem and I have fixed. Please make sure some things as written bellow :

   Mail::send('emails.auth.activate', array('link'=> URL::route('account-activate', $code),'username'=>$user->username),function($message) use ($user) {
                        $message->to($user->email , $user->username)->subject('Active your account !');

                    });

This should be your emails.activation

    Hello {{ $username }} , <br> <br> <br>

    We have created your account ! Awesome ! Please activate by clicking the   following link <br> <br> <br>
   ----- <br>
      {{ $link }} <br> <br> <br>
       ---- 

The answer to your why you can't call $email variable into your mail sending function. You need to call $user variable then you can write your desired variable as $user->variable

Thank You :)

you can directly run this command

sudo rabbitmqctl purge_queue queue_name

Small edit to @seengee answer: In order to work, you need curly braces around the variable, otherwise you'll get an error.

header("Content-type: {$imginfo['mime']}");

You want to do something like this:

# with is like your try .. finally block in this case
with open('stats.txt', 'r') as file:
    # read a list of lines into data
    data = file.readlines()

print data
print "Your name: " + data[0]

# now change the 2nd line, note that you have to add a newline
data[1] = 'Mage\n'

# and write everything back
with open('stats.txt', 'w') as file:
    file.writelines( data )

The reason for this is that you can't do something like "change line 2" directly in a file. You can only overwrite (not delete) parts of a file - that means that the new content just covers the old content. So, if you wrote 'Mage' over line 2, the resulting line would be 'Mageior'.

One approach would be to take a defaults object and merge it with the target object. The target object would override values in the defaults object.

jQuery has the .extend() method that does this. jQuery is not needed however as there are vanilla JS implementations such as can be found here:

To compile php from source with MySQL native driver (mysqlnd),

cd /php/source/path
./configure <other-options> --with-mysql --with-mysqli --with-pdo-mysql
make clean    # required if there was a previous make, which could cause various errors during make
make
make install

From /php/source/path/configure --help.

--with-mysql=DIR        Include MySQL support.  DIR is the MySQL base
                      directory, if no DIR is passed or the value is
                      mysqlnd the MySQL native driver will be used
--with-mysqli=FILE      Include MySQLi support.  FILE is the path
                      to mysql_config.  If no value or mysqlnd is passed
                      as FILE, the MySQL native driver will be used
--with-pdo-mysql=DIR    PDO: MySQL support. DIR is the MySQL base directory
                      If no value or mysqlnd is passed as DIR, the
                      MySQL native driver will be used

One or more PHP MySQL extensions can be included by using these options.
If a value is not passed to these options, or if the value is mysqlnd, MySQL native driver will be used.

You can use tool dpkg for managing packages in Debian operating system.

Example

dpkg --get-selections | grep mysql if it's listed as installed, you got it. Else you need to get it.

Instead of having to account for window.location.protocol and window.location.origin, and possibly missing a specified port number, etc., just grab everything up to the 3rd "/":

// get nth occurrence of a character c in the calling string
String.prototype.nthIndex = function (n, c) {
    var index = -1;
    while (n-- > 0) {
        index++;
        if (this.substring(index) == "") return -1; // don't run off the end
        index += this.substring(index).indexOf(c);
    }
    return index;
}

// get the base URL of the current page by taking everything up to the third "/" in the URL
function getBaseURL() {
    return document.URL.substring(0, document.URL.nthIndex(3,"/") + 1);
}

''.join('%02x'%i for i in input)

static before a global variable means that this variable is not accessible from outside the compilation module where it is defined.

E.g. imagine that you want to access a variable in another module:

foo.c

int var; // a global variable that can be accessed from another module
// static int var; means that var is local to the module only.
...

bar.c

extern int var; // use the variable in foo.c
...

Now if you declare var to be static you can't access it from anywhere but the module where foo.c is compiled into.

Note, that a module is the current source file, plus all included files. i.e. you have to compile those files separately, then link them together.

I had the same problem. I had to follow these steps to resolve the issue:

1. Make sure you have the following dependencies:

    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-core</artifactId>
        <version>${jackson-version}</version> // 2.4.3
    </dependency>

2. Create the following filter:

    public class CORSFilter extends OncePerRequestFilter {

        @Override
        protected void doFilterInternal(HttpServletRequest request,
                                        HttpServletResponse response, FilterChain filterChain)
                throws ServletException, IOException {

            String origin = request.getHeader("origin");
            origin = (origin == null || origin.equals("")) ? "null" : origin;
            response.addHeader("Access-Control-Allow-Origin", origin);
            response.addHeader("Access-Control-Allow-Methods", "POST, GET, PUT, UPDATE, DELETE, OPTIONS");
            response.addHeader("Access-Control-Allow-Credentials", "true");
            response.addHeader("Access-Control-Allow-Headers",
                    "Authorization, origin, content-type, accept, x-requested-with");

            filterChain.doFilter(request, response);
        }
    }

3. Apply the above filter for the requests in web.xml

    <filter>
        <filter-name>corsFilter</filter-name>
        <filter-class>com.your.package.CORSFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>corsFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

I hope this is useful to somebody.

If you use bootstrap 4, you can hide element that way

className={this.state.hideElement ? "invisible" : "visible"}

For query: SELECT * FROM (SELECT id, product FROM product) as product you can use:

$sub_query_from = '(SELECT id, product FROM product ) as product';
$this->db->select();
$this->db->from($sub_query_from);
$query = $this->db->get()

Please notice, that in sub_query_from string you must use spaces between ... product ) as...

Everybody that using: var myVar = 'token', is probably the worst idea. I can print it dirrectly in the console. You need to encrypt on the client side, then decrypt on server side.

You can use show innodb status (or show engine innodb status for newer versions of mysql) to get a list of all the actions currently pending inside the InnoDB engine. Buried in the wall of output will be the transactions, and what internal process ID they're running under.

You won't be able to force a commit or rollback of those transactions, but you CAN kill the MySQL process running them, which does essentially boil down to a rollback. It kills the processes' connection and causes MySQL to clean up the mess its left.

Here's what you'd want to look for:

------------
TRANSACTIONS
------------
Trx id counter 0 140151
Purge done for trx's n:o < 0 134992 undo n:o < 0 0
History list length 10
LIST OF TRANSACTIONS FOR EACH SESSION:
---TRANSACTION 0 0, not started, process no 17004, OS thread id 140621902116624
MySQL thread id 10594, query id 10269885 localhost marc
show innodb status

In this case, there's just one connection to the InnoDB engine right now (my login, running the show query). If that line were an actual connection/stuck transaction you'd want to terminate, you'd then do a kill 10594.

dict.allKeys is not a String. It is a [String], exactly as the error message tells you (assuming, of course, that the keys are all strings; this is exactly what you are asserting when you say that).

So, either start by typing componentArray as [AnyObject], because that is how it is typed in the Cocoa API, or else, if you cast dict.allKeys, cast it to [String], because that is how you have typed componentArray.

The process of assembling tree nodes is similar to the process of assembling lists. We have a constructor for tree nodes that initializes the instance variables.

public Tree (Object cargo, Tree left, Tree right) { 
    this.cargo = cargo; 
    this.left = left; 
    this.right = right; 
} 

We allocate the child nodes first:

Tree left = new Tree (new Integer(2), null, null); 
Tree right = new Tree (new Integer(3), null, null); 

We can create the parent node and link it to the children at the same time:

Tree tree = new Tree (new Integer(1), left, right); 

Before adding a class you should check if it already had class with .hasClass() method

For your specific question. You should be putting your stuff in Cascading Stylesheet. It's best practice to separate design and functionality.

so the proposed solution of adding and removing class names is best practice.

however when you are manipulating elements you don't control of how they are rendered. removeAttr('style') is BEST way to remove all inline styles.

Check out this solution VBA Compact Current Database.

Basically it says this should work

Public Sub CompactDB() 
    CommandBars("Menu Bar").Controls("Tools").Controls ("Database utilities"). _
    Controls("Compact and repair database...").accDoDefaultAction 
End Sub 

System.IO.File.Create(@"C:\Temp.txt");

As others have pointed out, you should dispose of this object or wrap it in an empty using statement.

using (System.IO.File.Create(@"C:\Temp.txt"));

If you don't use a passphrase, then the private key is not encrypted with any symmetric cipher - it is output completely unprotected.

You can generate a keypair, supplying the password on the command-line using an invocation like (in this case, the password is foobar):

openssl genrsa -aes128 -passout pass:foobar 3072

However, note that this passphrase could be grabbed by any other process running on the machine at the time, since command-line arguments are generally visible to all processes.

A better alternative is to write the passphrase into a temporary file that is protected with file permissions, and specify that:

openssl genrsa -aes128 -passout file:passphrase.txt 3072

Or supply the passphrase on standard input:

openssl genrsa -aes128 -passout stdin 3072

You can also used a named pipe with the file: option, or a file descriptor.

To then obtain the matching public key, you need to use openssl rsa, supplying the same passphrase with the -passin parameter as was used to encrypt the private key:

openssl rsa -passin file:passphrase.txt -pubout

(This expects the encrypted private key on standard input - you can instead read it from a file using -in <file>).

Example of creating a 3072-bit private and public key pair in files, with the private key pair encrypted with password foobar:

openssl genrsa -aes128 -passout pass:foobar -out privkey.pem 3072
openssl rsa -in privkey.pem -passin pass:foobar -pubout -out privkey.pub

put the following in ~/.gdbinit

define print_vector
    if $argc == 2
        set $elem = $arg0.size()
        if $arg1 >= $arg0.size()
            printf "Error, %s.size() = %d, printing last element:\n", "$arg0", $arg0.size()
            set $elem = $arg1 -1
        end
        print *($arg0._M_impl._M_start + $elem)@1
    else
        print *($arg0._M_impl._M_start)@$arg0.size()
    end
end

document print_vector
Display vector contents
Usage: print_vector VECTOR_NAME INDEX
VECTOR_NAME is the name of the vector
INDEX is an optional argument specifying the element to display
end

After restarting gdb (or sourcing ~/.gdbinit), show the associated help like this

gdb) help print_vector
Display vector contents
Usage: print_vector VECTOR_NAME INDEX
VECTOR_NAME is the name of the vector
INDEX is an optional argument specifying the element to display

Example usage:

(gdb) print_vector videoconfig_.entries 0
$32 = {{subChannelId = 177 '\261', sourceId = 0 '\000', hasH264PayloadInfo = false, bitrate = 0,     payloadType = 68 'D', maxFs = 0, maxMbps = 0, maxFps = 134, encoder = 0 '\000', temporalLayers = 0 '\000'}}

According to Opera the CSS3 standard does not define the use of border-radius on TDs. My experience is that Firefox and Chrome support it but Opera does not (don't know about IE). The workaround is to wrap the td content in a div and then apply the border-radius to the div.

In my case the problem is actually with OpenFeint API project. I have added OpenFeint as library project:

.

It is also added into build path, ADT tools 16 gives error with this sceneario.

Right click on your project and click build path, configure the build path and then see the image and remove your project OpenFeint from here and all is done :)

The outfile should be in binary mode.

outFile = open('output.xml', 'wb')

The use operator is for giving aliases to names of classes, interfaces or other namespaces. Most use statements refer to a namespace or class that you'd like to shorten:

use My\Full\Namespace;

is equivalent to:

use My\Full\Namespace as Namespace;
// Namespace\Foo is now shorthand for My\Full\Namespace\Foo

If the use operator is used with a class or interface name, it has the following uses:

// after this, "new DifferentName();" would instantiate a My\Full\Classname
use My\Full\Classname as DifferentName;

// global class - making "new ArrayObject()" and "new \ArrayObject()" equivalent
use ArrayObject;

The use operator is not to be confused with autoloading. A class is autoloaded (negating the need for include) by registering an autoloader (e.g. with spl_autoload_register). You might want to read PSR-4 to see a suitable autoloader implementation.

You're looking for dir to return the directory contents.

To loop over the results, you can simply do the following:

dirlist = dir('.');
for i = 1:length(dirlist)
    dirlist(i)
end

This should give you output in the following format, e.g.:

name: 'my_file'
date: '01-Jan-2010 12:00:00'
bytes: 56
isdir: 0
datenum: []

Chances are slim that any of the above answers wouldn't has solved your problem. Nonetheless, I'm sharing my method which always works for me for different format of datetimes.

//Definition   
     public static DateTime ConvertPlainStringToDatetime(string Date, string inputFormat, string  outputFormat)
            {
                DateTime date;
                CultureInfo enUS = new CultureInfo("en-US");
                DateTime.TryParseExact(Date, inputFormat, enUS,
                                    DateTimeStyles.AdjustToUniversal, out date);

                string formatedDateTime = date.ToString(outputFormat);
                return Convert.ToDateTime(formatedDateTime);   
            }
//Calling

    string oFormat = "yyyy-MM-dd HH:mm:ss";
    DateTime requiredDT = ConvertPlainStringToDatetime("20190205","yyyyMMddHHmmss", oFormat  );
    DateTime requiredDT = ConvertPlainStringToDatetime("20190508-12:46:42","yyyyMMdd-HH:mm:ss", oFormat);

There is a contemporary way to do that for primitives. Use BYTES of types.

System.out.println("byte " + Byte.BYTES);
System.out.println("char " + Character.BYTES);
System.out.println("int " + Integer.BYTES);
System.out.println("long " + Long.BYTES);
System.out.println("short " + Short.BYTES);
System.out.println("double " + Double.BYTES);
System.out.println("float " + Float.BYTES);

It results in,

byte 1
char 2
int 4
long 8
short 2
double 8
float 4

To create both of the created_at and updated_at columns:

$t->timestamp('created_at')->default(DB::raw('CURRENT_TIMESTAMP'));
$t->timestamp('updated_at')->default(DB::raw('CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP'));

You will need MySQL version >= 5.6.5 to have multiple columns with CURRENT_TIMESTAMP

If you are converting it to string, you can easily do it like this.

I'm taking date as your DateTime object.

date.ToString("d");

This will give you only the date.

Here is simple CSS rules that put any div in the center

.centered {
  position: fixed;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
}

I had the same problem but Dirk's solution didn't seem to work. I was getting this warning messege every time

"prob" is not a graphical parameter

I read through ?hist and found about freq: a logical vector set TRUE by default.

the code that worked for me is

hist(x,freq=FALSE)
lines(density(x),na.rm=TRUE)

From the header of '/etc/mysql/my.cnf':

MariaDB programs look for option files in a set of
locations which depend on the deployment platform.
[...] For information about these locations, do:
'my_print_defaults --help' and see what is printed under
"Default options are read from the following files in the given order:"
More information at: http://dev.mysql.com/doc/mysql/en/option-files.html

This is in slight response to Joel's comment about making a slighly more optimized version. Instead of returning a random date directly, why not return a generator function which can be called repeatedly to create a random date.

Func<DateTime> RandomDayFunc()
{
    DateTime start = new DateTime(1995, 1, 1); 
    Random gen = new Random(); 
    int range = ((TimeSpan)(DateTime.Today - start)).Days; 
    return () => start.AddDays(gen.Next(range));
}

I like these two because they seem the most logical, the latter being shorter and probably fastest (shown here using set literal syntax which has been backported to Python 2.7):

all(x in {'a', 'b', 'c'} for x in ['a', 'b'])
#   or
{'a', 'b'}.issubset({'a', 'b', 'c'})

In pre-commit/post-checkout an option would be to use "mtree" (FreeBSD), or "fmtree" (Ubuntu) utility which "compares a file hierarchy against a specification, creates a specification for a file hierarchy, or modifies a specification."

The default set are flags, gid, link, mode, nlink, size, time, type, and uid. This can be fitted to the specific purpose with -k switch.

The problem is that you have a circular import: in app.py

from mod_login import mod_login

in mod_login.py

from app import app

This is not permitted in Python. See Circular import dependency in Python for more info. In short, the solution are

• either gather everything in one big file
• delay one of the import using local import

Follow bellow steps:

shell> mysqldump -hlocalhost -uroot -p  database1  > dump.sql

mysql> CREATE DATABASE database2;

shell> mysql -hlocalhost -uroot -p database2 < dump.sql

If you want to drop database1 otherwise leave it.

mysql> DROP DATABASE database1;

Note : shell> denote command prompt and mysql> denote mysql prompt.

The IF statement has these forms in PL/SQL:

IF THEN
IF THEN ELSE
IF THEN ELSIF

You have used elseif which in terms of PL/SQL is wrong. That need to be replaced with ELSIF.

So your code should appear like this.

    declare
        var_number number;
    begin
        var_number := 10;
        if var_number > 100 then
           dbms_output.put_line(var_number ||' is greater than 100');
--elseif should be replaced with elsif
        elsif var_number < 100 then
           dbms_output.put_line(var_number ||' is less than 100');
        else
           dbms_output.put_line(var_number ||' is equal to 100');
        end if;
    end; 

If it instead returned Option[QueueObject] you could use a construct like getObject.foreach { QueueManager.add }. You can wrap it right inline with Option(getObject).foreach ... because Option[QueueObject](null) is None.

The accepted answer crashes on filenames with space. I'm at this point not sure how to update the alias command, so I'll put the improved version here:

git ls-files -z -o --exclude-standard | xargs -0 git add

Instead of ng-options="product as product.label for product in products"> in the select element, you can even use this:

<option ng-repeat="product in products" value="{{product.label}}">{{product.label}}

which works just fine as well.

Yes. You can have a span within a span. Your problem stems from something else.

Tumblr has a public API that provides JSON. You can get a dump of posts using a simple url like http://puppygifs.tumblr.com/api/read/json.

Instead of QString::number() i would use QLocale::toString(), so i can get locale aware group seperatores like german "1.234.567,89".

There's no need to require a big library like jQuery to accomplish this, if you don't want to. To achieve this with built-in DOM manipulation, get a collection of the li siblings in an array, and on click, check the indexOf the clicked element in that array.

const lis = [...document.querySelectorAll('#wizard > li')];_x000D_
lis.forEach((li) => {_x000D_
  li.addEventListener('click', () => {_x000D_
    const index = lis.indexOf(li);_x000D_
    console.log(index);_x000D_
  });_x000D_
});

<ul id="wizard">_x000D_
    <li>Step 1</li>_x000D_
    <li>Step 2</li>_x000D_
</ul>

Or, with event delegation:

const lis = [...document.querySelectorAll('#wizard li')];_x000D_
document.querySelector('#wizard').addEventListener('click', ({ target }) => {_x000D_
  // Make sure the clicked element is a <li> which is a child of wizard:_x000D_
  if (!target.matches('#wizard > li')) return;_x000D_
  _x000D_
  const index = lis.indexOf(target);_x000D_
  console.log(index);_x000D_
});

<ul id="wizard">_x000D_
    <li>Step 1</li>_x000D_
    <li>Step 2</li>_x000D_
</ul>

Or, if the child elements may change dynamically (like with a todo list), then you'll have to construct the array of lis on every click, rather than beforehand:

const wizard = document.querySelector('#wizard');_x000D_
wizard.addEventListener('click', ({ target }) => {_x000D_
  // Make sure the clicked element is a <li>_x000D_
  if (!target.matches('li')) return;_x000D_
  _x000D_
  const lis = [...wizard.children];_x000D_
  const index = lis.indexOf(target);_x000D_
  console.log(index);_x000D_
});

<ul id="wizard">_x000D_
    <li>Step 1</li>_x000D_
    <li>Step 2</li>_x000D_
</ul>

I would use isset and empty:

session_start();
if(isset($_SESSION['blah']) && !empty($_SESSION['blah'])) {
   echo 'Set and not empty, and no undefined index error!';
}

array_key_exists is a nice alternative to using isset to check for keys:

session_start();
if(array_key_exists('blah',$_SESSION) && !empty($_SESSION['blah'])) {
    echo 'Set and not empty, and no undefined index error!';
}

Make sure you're calling session_start before reading from or writing to the session array.

I've been working with JetBrains dotTrace for WinForms and Console Apps (not tested on ASP.net yet), and it works quite well:

They recently also added a "Personal License" that is significantly cheaper than the corporate one. Still, if anyone else knows some cheaper or even free ones, I'd like to hear as well :-)

It might be helpful to address this question from a package deployment perspective.

There are many tutorials out there that explain how to publish a package to PyPi. Below are a couple I have used;

medium
real python

My experience is that most of these tutorials only have you use the .tar of the source, not a wheel. Thus, when installing packages created using these tutorials, I've received the "Failed to build wheel" error.

I later found the link on PyPi to the Python Software Foundation's docs PSF Docs. I discovered that their setup and build process is slightly different, and does indeed included building a wheel file.

After using the officially documented method, I no longer received the error when installing my packages.

So, the error might simply be a matter of how the developer packaged and deployed the project. None of us were born knowing how to use PyPi, and if they happened upon the wrong tutorial -- well, you can fill in the blanks.

I'm sure that is not the only reason for the error, but I'm willing to bet that is a major reason for it.

As of March 2020, simply:

• Invite @RawDataBot to your group.

Upon joining it will output a JSON file where your chat id will be located at message.chat.id.

"message": {
    "chat": {
        "id": -210987654,
        "title": ...,
        "type": "group",
        ...
    }
    ...
}

Be sure to kick @RawDataBot from your group afterwards.

Another option could be:

var initial = function() {
    console.log( 'initial function!' );
}

var iWantToExecuteThisOneToo = function () {
    console.log( 'the other function that i wanted to execute!' );
}

function extendFunction( oldOne, newOne ) {
    return (function() {
        oldOne();
        newOne();
    })();
}

var extendedFunction = extendFunction( initial, iWantToExecuteThisOneToo );

Everybody seems to refer to date being a column in the table.
I dont think this is good practice. The word date might just be a keyword in some coding language (maybe Oracle) so please change the columnname date to maybe JDate.
So will the following work better:

SELECT * FROM jokes WHERE JDate >= CURRENT_DATE() ORDER BY JScore DESC;

So we have a table called Jokes with columns JScore and JDate.

The Node.js project recently pushed out a new stable version with the 0.10.0 release Use the following command on Ubuntu 13x sudo apt-get install nodejs=0.10.18-1chl1~raring1

Use $_SESSION directly to set variables. Like this:

$_SESSION['name'] = 'stack';

Instead of:

$name = 'stack';
session_register("name");

This is 2018 and still there is no native method to completely clear canvas for redrawing. clearRect() does not clear the canvas completely. Non-fill type drawings are not cleared out (eg. rect())

1.To completely clear canvas irrespective of how you draw:

context.clearRect(0, 0, context.canvas.width, context.canvas.height);
context.beginPath();

Pros: Preserves strokeStyle, fillStyle etc.; No lag;

Cons: Unnecessary if you are already using beginPath before drawing anything

2.Using the width/height hack:

context.canvas.width = context.canvas.width;

OR

context.canvas.height = context.canvas.height;

Pros: Works with IE Cons: Resets strokeStyle, fillStyle to black; Laggy;

I was wondering why a native solution does not exist. Actually, clearRect() is considered as the single line solution because most users do beginPath() before drawing any new path. Though beginPath is only to be used while drawing lines and not closed path like rect().

This is the reason why the accepted answer did not solve my problem and I ended up wasting hours trying different hacks. Curse you mozilla

@nickf's correct. However, to be a little more precise:

// if you try to print it, it will return something like:
// Sat Mar 21 2009 20:13:07 GMT-0400 (Eastern Daylight Time)
// This time comes from the user's machine.
var myDate = new Date();

So if you want to display it as mm/dd/yyyy, you would do this:

var displayDate = (myDate.getMonth()+1) + '/' + (myDate.getDate()) + '/' + myDate.getFullYear();

Check out the full reference of the Date object. Unfortunately it is not nearly as nice to print out various formats as it is with other server-side languages. For this reason there-are-many-functions available in the wild.

This is method I created to handle async scenarios with ForEach.

• If one of tasks fails then other tasks will continue their execution.
• You have ability to add function that will be executed on every exception.
• Exceptions are being collected as aggregateException at the end and are available for you.
• Can handle CancellationToken

I don't know how stubhub's api works, but generally it should look like this:

s = requests.Session()
data = {"login":"my_login", "password":"my_password"}
url = "http://example.net/login"
r = s.post(url, data=data)

Now your session contains cookies provided by login form. To access cookies of this session simply use

s.cookies

Any further actions like another requests will have this cookie

To make multiple checking statements more readable (and avoid nested ifs):

var tmp = 'Test[[email protected]]';

var posStartEmail = undefined;
var posEndEmail = undefined;
var email = undefined;

do {
    if (tmp.toLowerCase().substring(0,4) !== 'test') { break; }

    posStartEmail = tmp.toLowerCase().substring(4).indexOf('[');
    posEndEmail = tmp.toLowerCase().substring(4).indexOf(']');

    if (posStartEmail === -1 || posEndEmail === -1) { break; }

    email = tmp.substring(posStartEmail+1+4,posEndEmail);

    if (email.indexOf('@') === -1) { break; }

// all checks are done - do what you intend to do

    alert ('All checks are ok')

    break; // the most important break of them all

} while(true);

TL;DR

Here's a version where you don't need a human to read a value and type it out themselves.

CREATE SEQUENCE foo_a_seq OWNED BY foo.a;
SELECT setval('foo_a_seq', coalesce(max(a), 0) + 1, false) FROM foo;
ALTER TABLE foo ALTER COLUMN a SET DEFAULT nextval('foo_a_seq'); 

Another option would be to employ the reusable Function shared at the end of this answer.

A non-interactive solution

Just adding to the other two answers, for those of us who need to have these Sequences created by a non-interactive script, while patching a live-ish DB for instance.

That is, when you don't wanna SELECT the value manually and type it yourself into a subsequent CREATE statement.

In short, you can not do:

CREATE SEQUENCE foo_a_seq
    START WITH ( SELECT max(a) + 1 FROM foo );

... since the START [WITH] clause in CREATE SEQUENCE expects a value, not a subquery.

Note: As a rule of thumb, that applies to all non-CRUD (i.e.: anything other than INSERT, SELECT, UPDATE, DELETE) statements in pgSQL AFAIK.

However, setval() does! Thus, the following is absolutely fine:

SELECT setval('foo_a_seq', max(a)) FROM foo;

If there's no data and you don't (want to) know about it, use coalesce() to set the default value:

SELECT setval('foo_a_seq', coalesce(max(a), 0)) FROM foo;
--                         ^      ^         ^
--                       defaults to:       0

However, having the current sequence value set to 0 is clumsy, if not illegal.
Using the three-parameter form of setval would be more appropriate:

--                                             vvv
SELECT setval('foo_a_seq', coalesce(max(a), 0) + 1, false) FROM foo;
--                                                  ^   ^
--                                                is_called

Setting the optional third parameter of setval to false will prevent the next nextval from advancing the sequence before returning a value, and thus:

the next nextval will return exactly the specified value, and sequence advancement commences with the following nextval.

— from this entry in the documentation

On an unrelated note, you also can specify the column owning the Sequence directly with CREATE, you don't have to alter it later:

CREATE SEQUENCE foo_a_seq OWNED BY foo.a;

In summary:

CREATE SEQUENCE foo_a_seq OWNED BY foo.a;
SELECT setval('foo_a_seq', coalesce(max(a), 0) + 1, false) FROM foo;
ALTER TABLE foo ALTER COLUMN a SET DEFAULT nextval('foo_a_seq'); 

Using a Function

Alternatively, if you're planning on doing this for multiple columns, you could opt for using an actual Function.

CREATE OR REPLACE FUNCTION make_into_serial(table_name TEXT, column_name TEXT) RETURNS INTEGER AS $$
DECLARE
    start_with INTEGER;
    sequence_name TEXT;
BEGIN
    sequence_name := table_name || '_' || column_name || '_seq';
    EXECUTE 'SELECT coalesce(max(' || column_name || '), 0) + 1 FROM ' || table_name
            INTO start_with;
    EXECUTE 'CREATE SEQUENCE ' || sequence_name ||
            ' START WITH ' || start_with ||
            ' OWNED BY ' || table_name || '.' || column_name;
    EXECUTE 'ALTER TABLE ' || table_name || ' ALTER COLUMN ' || column_name ||
            ' SET DEFAULT nextVal(''' || sequence_name || ''')';
    RETURN start_with;
END;
$$ LANGUAGE plpgsql VOLATILE;

Use it like so:

INSERT INTO foo (data) VALUES ('asdf');
-- ERROR: null value in column "a" violates not-null constraint

SELECT make_into_serial('foo', 'a');
INSERT INTO foo (data) VALUES ('asdf');
-- OK: 1 row(s) affected

I noticed a very anoying gotcha in moving to scss files!!! One MUST move from a simple: styleUrls: ['app.component.scss'] to styleUrls: ['./app.component.scss'] (add ./) in app.component.ts

Which ng does when you generate a new project, but seemingly not when the default project is created. If you see resolve errors during ng build, check for this issue. It only took me ~ 1 hour.

Just super(); alone will call the default constructor, if it exists of a class's superclass. But you must explicitly write the default constructor yourself. If you don't a Java will generate one for you with no implementations, save super(); , referring to the universal Superclass Object, and you can't call it in a subclass.

public class Alien{
   public Alien(){ //Default constructor is written out by user
   /** Implementation not shown…**/
   }
}

public class WeirdAlien extends Alien{
   public WeirdAlien(){
   super(); //calls the default constructor in Alien.
   }

}

Delete application IDs is allowed. Make sure you deleted all certificates, APNS certs and provisioning profiles associated with your application. Then go to Identitifies --> App IDs, select the application ID, Edit and Delete button should be enabled.

You convert type np.dot(X, T) to float32 like this:

z=np.array(np.dot(X, T),dtype=np.float32)

def sigmoid(X, T):
    return (1.0 / (1.0 + np.exp(-z)))

Hopefully it will finally work!

Just Change the Connection mysql string to 127.0.0.1 and it will work

One thing you need to realize is in Ruby everything is an object. Given that, if you don't define your methods within Module or Class, Ruby will put it within the Object class. So, your code will be local to the Object scope.

A typical approach on Object Oriented Programming is encapsulate all logic within a class:

class Point
  attr_accessor :x, :y

  # If we don't specify coordinates, we start at 0.
  def initialize(x = 0, y = 0)
    # Notice that `@` indicates instance variables.
    @x = x
    @y = y
  end

  # Here we override the `+' operator.
  def +(point)
    Point.new(self.x + point.x, self.y + point.y)
  end

  # Here we draw the point.
  def draw(offset = nil)
    if offset.nil?
      new_point = self
    else
      new_point = self + offset 
    end
    new_point.draw_absolute
  end

  def draw_absolute
    puts "x: #{self.x}, y: #{self.y}"
  end
end

first_point = Point.new(100, 200)
second_point = Point.new(3, 4)

second_point.draw(first_point)

Hope this clarifies a bit.

I have just encountered a similar need. In my case, slf4j is configured with the java logging adapter (the jdk14 one). Using the following code snippet I have managed to change the debug level at runtime:

Logger logger = LoggerFactory.getLogger("testing");
java.util.logging.Logger julLogger = java.util.logging.Logger.getLogger("testing");
julLogger.setLevel(java.util.logging.Level.FINE);
logger.debug("hello world");

document.getElementsByClassName returns a NodeList, not a single element, I'd recommend either using jQuery, since you'd only have to use something like $('.new').toggle()

or if you want plain JS try :

function toggle_by_class(cls, on) {
    var lst = document.getElementsByClassName(cls);
    for(var i = 0; i < lst.length; ++i) {
        lst[i].style.display = on ? '' : 'none';
    }
}

According to this post, it's much better now:

// pick out one album
JObject jalbum = albums[0] as JObject;

// Copy to a static Album instance
Album album = jalbum.ToObject<Album>();

Alternatively you could read you csv with header=None and then add it with df.columns:

Cov = pd.read_csv("path/to/file.txt", sep='\t', header=None)
Cov.columns = ["Sequence", "Start", "End", "Coverage"]

Install ejs template

npm install ejs --save

Refer ejs in app.js

app.set('views', path.join(__dirname, 'views'));`
app.set('view engine', 'ejs');

Create a ejs template in views like views/indes.ejs & use ejs tempalte in router

router.get('/', function(req, res, next) {
    res.render('index', { title: 'Express' });
});

I shall refer to the same sample of data as posted in the question:

import numpy as np
import pandas as pd
df = pd.DataFrame(np.random.randn(8, 4), columns=['A','B','C','D'])
print('The original data frame is: \n{}'.format(df))

Running this code will give you

The original data frame is:

          A         B         C         D
0  0.494824 -0.328480  0.818117  0.100290
1  0.239037  0.954912 -0.186825 -0.651935
2 -1.818285 -0.158856  0.359811 -0.345560
3 -0.070814 -0.394711  0.081697 -1.178845
4 -1.638063  1.498027 -0.609325  0.882594
5 -0.510217  0.500475  1.039466  0.187076
6  1.116529  0.912380  0.869323  0.119459
7 -1.046507  0.507299 -0.373432 -1.024795

Now you wish to append a new row to this data frame, which doesn't need to be copy of any other row in the data frame. @Alon suggested an interesting approach to use df.loc to append a new row with different index. The issue, however, with this approach is if there is already a row present at that index, it will be overwritten by new values. This is typically the case for datasets when row index is not unique, like store ID in transaction datasets. So a more general solution to your question is to create the row, transform the new row data into a pandas series, name it to the index you want to have and then append it to the data frame. Don't forget to overwrite the original data frame with the one with appended row. The reason is df.append returns a view of the dataframe and does not modify its contents. Following is the code:

row = pd.Series({'A':10,'B':20,'C':30,'D':40},name=3)
df = df.append(row)
print('The new data frame is: \n{}'.format(df))

Following would be the new output:

The new data frame is:

           A          B          C          D
0   0.494824  -0.328480   0.818117   0.100290
1   0.239037   0.954912  -0.186825  -0.651935
2  -1.818285  -0.158856   0.359811  -0.345560
3  -0.070814  -0.394711   0.081697  -1.178845
4  -1.638063   1.498027  -0.609325   0.882594
5  -0.510217   0.500475   1.039466   0.187076
6   1.116529   0.912380   0.869323   0.119459
7  -1.046507   0.507299  -0.373432  -1.024795
3  10.000000  20.000000  30.000000  40.000000

If you want it based on the screen height, and not the window height:

const height = 0.7 * screen.height

// jQuery
$('.header').height(height)

// Vanilla JS
document.querySelector('.header').style.height = height + 'px'

// If you have multiple <div class="header"> elements
document.querySelectorAll('.header').forEach(function(node) {
  node.style.height = height + 'px'
})

Try this:

import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import java.net.URL;
import javax.imageio.ImageIO;

public class WriteImage 
{   
    public static void main( String[] args )
    {
        BufferedImage image = null;
        try {

            URL url = new URL("URL_IMAGE");
            image = ImageIO.read(url);

            ImageIO.write(image, "jpg",new File("C:\\out.jpg"));
            ImageIO.write(image, "gif",new File("C:\\out.gif"));
            ImageIO.write(image, "png",new File("C:\\out.png"));

        } catch (IOException e) {
            e.printStackTrace();
        }
        System.out.println("Done");
    }
}

You can get current href value by this code:

$(this).attr("href");

To get href value by ID

$("#mylink").attr("href");

No need to hack your editor, or switch editors.

Instead we can come up with a script to watch your development directories and chmod files as they're created. This is what I've done in the attached bash script. You probably want to read through the comments and edit the 'config' section as fits your needs, then I would suggest putting it in your $HOME/bin/ directory and adding its execution to your $HOME/.login or similar file. Or you can just run it from the terminal.

This script does require inotifywait, which comes in the inotify-tools package on Ubuntu,

sudo apt-get install inotify-tools

Suggestions/edits/improvements are welcome.

# I recommend adding this script to your $HOME/.login or similar to have it

You don't have to use atan2 to calculate the angle between two vectors. If you just want the quickest way, you can use dot(v1, v2)=|v1|*|v2|*cos A to get

A = Math.acos( dot(v1, v2)/(v1.length()*v2.length()) );

Grab the radio group and look at the children to see if any are unchecked.

RadioGroup rg = (RadioGroup) view;
int checked = savedInstanceState.getInt(wrap.getAttributeName());

if(checked != -1) {
    RadioButton btn = (RadioButton) rg.getChildAt(checked);
    btn.toggle();
}

Check out https://github.com/hrakaroo/glob-library-java.

It's a zero dependency library in Java for doing glob (and sql like) type of comparisons. Over a large data set it is faster than translating to a regular expression.

Basic syntax

MatchingEngine m = GlobPattern.compile("dog%cat\%goat_", '%', '_', GlobPattern.HANDLE_ESCAPES);
if (m.matches(str)) { ... }

Your regex does not work because [] defines a character class, but what you want is a lookahead:

(?=) - Positive look ahead assertion foo(?=bar) matches foo when followed by bar
(?!) - Negative look ahead assertion foo(?!bar) matches foo when not followed by bar
(?<=) - Positive look behind assertion (?<=foo)bar matches bar when preceded by foo
(?<!) - Negative look behind assertion (?<!foo)bar matches bar when NOT preceded by foo
(?>) - Once-only subpatterns (?>\d+)bar Performance enhancing when bar not present
(?(x)) - Conditional subpatterns
(?(3)foo|fu)bar - Matches foo if 3rd subpattern has matched, fu if not
(?#) - Comment (?# Pattern does x y or z)

So try: (?!bush)

I think the most efficient way to do this is this is using RemoveAt:

rows.RemoveAt(rows.Count - 1)

Wildcards can only be used in the ServerAlias rather than the ServerName. Something which had me stumped.

For your use case, the following should suffice

<VirtualHost *:80>
    ServerAlias *.example.com
    VirtualDocumentRoot /var/www/%1/
</VirtualHost>

Another option:

UPDATE `table` SET the_col = current_timestamp

Looks odd, but works as expected. If I had to guess, I'd wager this is slightly faster than calling now().

You can use standard JS toFixed method

var num = 5.56789;
var n=num.toFixed(2);

//5.57

In order to add commas (to separate 1000's) you can add regexp as follows (where num is a number):

num.toString().replace(/(\d)(?=(\d\d\d)+(?!\d))/g, "$1,")

//100000 => 100,000
//8000 => 8,000
//1000000 => 1,000,000

Complete example:

var value = 1250.223;
var num = '$' + value.toFixed(2).replace(/(\d)(?=(\d\d\d)+(?!\d))/g, "$1,");

//document.write(num) would write value as follows: $1,250.22

Separation character depends on country and locale. For some countries it may need to be .

We call it the "ant" menu. Guess it was a good time to change since everyone had just gotten used to the hamburger.

1. First of all you need to install Git software on your local development machine, e.g. Git Extensions.
2. Then do git init in the solution folder. That is the proper way to create a repository folder.
3. Set up a reasonable .gitignore file, so you don't commit unnecessary stuff.
4. git add
5. git commit
6. Add the proper remote, as described in your Team Foundation Server account git remote add origin <proper URL>
7. git push your code

Alternatively, there are detailed guides here using the Visual Studio integration.

In my case it was Avast Antivirus interfering with the connection. Actions to disable this feature: Avast -> Settings-> Components -> Mail Shield (Customize) -> SSL scanning -> uncheck "Scan SSL connections".

ES2020 Answer

The new Nullish Coalescing Operator, is finally available on JavaScript, though browser support is limited. According to the data from caniuse, only 48.34% of browsers are supported (as of April 2020).

According to the documentation,

The nullish coalescing operator (??) is a logical operator that returns its right-hand side operand when its left-hand side operand is null or undefined, and otherwise returns its left-hand side operand.

const options={
  filters:{
    firstName:'abc'
  } 
};
const filter = options.filters[0] ?? '';
const filter2 = options.filters[1] ?? '';

This will ensure that both of your variables will have a fallback value of '' if filters[0] or filters[1] are null, or undefined.

Do take note that the nullish coalescing operator does not return the default value for other types of falsy value such as 0 and ''. If you wish to account for all falsy values, you should be using the OR operator ||.

There's no way to initiate a file transfer back to/from local Windows from a SSH session opened in PuTTY window.

Though PuTTY supports connection-sharing.

While you still need to run a compatible file transfer client (pscp or psftp), no new login is required, it automatically (if enabled) makes use of an existing PuTTY session.

To enable the sharing see:
Sharing an SSH connection between PuTTY tools.

Even without connection-sharing, you can still use the psftp or pscp from Windows command line.

See How to use PSCP to copy file from Unix machine to Windows machine ...?

Note that the scp is OpenSSH program. It's primarily *nix program, but you can run it via Windows Subsystem for Linux or get a Windows build from Win32-OpenSSH (it is already built-in in the latest versions of Windows 10).

If you really want to download the files to a local desktop, you have to specify a target path as %USERPROFILE%\Desktop (what typically resolves to a path like C:\Users\username\Desktop).

Alternative way is to use WinSCP, a GUI SFTP/SCP client. While you browse the remote site, you can anytime open SSH terminal to the same site using Open in PuTTY command.
See Opening Session in PuTTY.

With an additional setup, you can even make PuTTY automatically navigate to the same directory you are browsing with WinSCP.
See Opening PuTTY in the same directory.

(I'm the author of WinSCP)

There isn’t a pure JavaScript generic solution, I’m afraid. JavaScript isn’t able to turn off the CSS :hover state itself.

You could try the following alternative workaround though. If you don’t mind mucking about in your HTML and CSS a little bit, it saves you having to reset every CSS property manually via JavaScript.

HTML

<body class="nojQuery">

CSS

/* Limit the hover styles in your CSS so that they only apply when the nojQuery 
class is present */

body.nojQuery ul#mainFilter a:hover {
    /* CSS-only hover styles go here */
}

JavaScript

// When jQuery kicks in, remove the nojQuery class from the <body> element, thus
// making the CSS hover styles disappear.

$(function(){}
    $('body').removeClass('nojQuery');
)

this could be a solution?

declare @step2cmd nvarchar(200)
DECLARE @rcount NUMERIC(18,0)   
set @step2cmd = 'select count(*) from uat.ap.ztscm_protocollo' --+ @nometab
EXECUTE @rcount=sp_executesql @step2cmd
select @rcount

If your image is stored in a ResourceDictionary, you can do it with only one line of code:

MyImage.Source = MyImage.FindResource("MyImageKeyDictionary") as ImageSource;

You can use the below for passing the raw text.

axios.post(
        baseUrl + 'applications/' + appName + '/dataexport/plantypes' + plan, 
        body, 
        {
            headers: { 
                'Authorization': 'Basic xxxxxxxxxxxxxxxxxxx',
                'Content-Type' : 'text/plain' 
            }
        }
).then(response => {
    this.setState({data:response.data});
    console.log(this.state.data);
});

Just have your raw text within body or pass it directly within quotes as 'raw text to be sent' in place of body.

The signature of the axios post is axios.post(url[, data[, config]]), so the data is where you pass your request body.

You can loop through the DataColumn and DataRow collections in your DataTable:

// Sum rows.
foreach (DataRow row in dt.Rows) {
    int rowTotal = 0;
    foreach (DataColumn col in row.Table.Columns) {
        Console.WriteLine(row[col]);
        rowTotal += Int32.Parse(row[col].ToString());
    }
    Console.WriteLine("row total: {0}", rowTotal);
}
// Sum columns.
foreach (DataColumn col in dt.Columns) {
    int colTotal = 0;
    foreach (DataRow row in col.Table.Rows) {
        Console.WriteLine(row[col]);
        colTotal += Int32.Parse(row[col].ToString());
    }
    Console.WriteLine("column total: {0}", colTotal);
}

Beware: The code above does not do any sort of checking before casting an object to an int.

EDIT: add a DataRow displaying the column sums

Try this to create a new row to display your column sums:

DataRow totalsRow = dt.NewRow();
foreach (DataColumn col in dt.Columns) {
    int colTotal = 0;
    foreach (DataRow row in col.Table.Rows) {
        colTotal += Int32.Parse(row[col].ToString());
    }
    totalsRow[col.ColumnName] = colTotal;
}
dt.Rows.Add(totalsRow);

This approach is fine if the data type of any of your DataTable's DataRows are non-numeric or if you want to inspect the value of each cell as you sum. Otherwise I believe @Tim's response using DataTable.Compute is a better.

string.join connects elements inside list of strings, not ints.

Use this generator expression instead :

values = ','.join(str(v) for v in value_list)

long numberOfPages = new BigDecimal(resultsSize).divide(new BigDecimal(pageSize), RoundingMode.UP).longValue();

I don't have much experience working with php but from a logic standpoint this is what I would do.

1. Loop through your result set from MySQL
2. In Excel you should already know what A,B,C should be because those are the columns and you know how many columns you are returning.
3. The row number can just be incremented with each time through the loop.

Below is some pseudocode illustrating this technique:

    for (int i = 0; i < MySQLResults.count; i++){
         $objPHPExcel->getActiveSheet()->setCellValue('A' . (string)(i + 1), MySQLResults[i].name); 
        // Add 1 to i because Excel Rows start at 1, not 0, so row will always be one off
         $objPHPExcel->getActiveSheet()->setCellValue('B' . (string)(i + 1), MySQLResults[i].number);
         $objPHPExcel->getActiveSheet()->setCellValue('C' . (string)(i + 1), MySQLResults[i].email);
    }

This probably isn't the most elegant way to do it, but it gets the job done.

Just replace '/Users/spencerlyon2/Desktop/test.csv' with the path to your file

Actually GitHub does not create an empty folder.

For example, to create a folder in C:\Users\Username\Documents\GitHub\Repository:

• Create a folder named docs

• Create a file name index.html under docs

• Open the GitHub for desktop application

  It will automatically sync, and it will be there.

Use the

Request.Form[]

for POST variables,

Request.QueryString[]

for GET.

You can recursively revert like this:

svn revert --recursive .

There is no way (without writing a creative script) to remove things that aren't under source control. I think the closest you could do is to iterate over all of the files, use then grep the result of svn list, and if the grep fails, then delete it.

EDIT: The solution for the creative script is here: Automatically remove Subversion unversioned files

So you could create a script that combines a revert with whichever answer in the linked question suits you best.

Yes web application is much better than web sites, because Web applications give us freedom:

1. To have multiple projects under one umbrella and establish project dependencies between. E.g. for PCS we can have following within web application-

   • Web portals
   • Notification Controller (for sending Email)
   • Business layer
   • Data Access layer
   • Exception Manager
   • Server utility
   • WCF Services (Common for all platforms)
   • List item

2. To run unit tests on code that is in the class files that are associated with ASP.NET pages

3. To refer to the classes those are associated with pages and user controls from standalone classes
4. To create a single assembly for the entire site
5. Control over the assembly name and version number that is generated for the site
6. To avoid putting source code on a production server. (You can avoid deploying source code to the IIS server. In some scenarios, such as shared hosting environments, you might be concerned about unauthorized access to source code on the IIS server. (For a web site project, you can avoid this risk by pre-compiling on a development computer and deploying the generated assemblies instead of the source code. However, in that case you lose some of the benefits of easy site updates.)
7. Performance Issue with Website(The first request to the web site might require the site to be compiled, which can result in a delay. And if the web site is running on an IIS server that is short on memory, including the entire site in a single assembly might use more memory than would be required for multiple assemblies.)

You can use angularjs form state form.$submitted. Initially form.$submitted value will be false and will became true after successful form submit.

The reason why you're getting that error is because you've declared your struct as:

struct {
 char name[32];
 int  size;
 int  start;
 int  popularity;
} stasher_file;

This is not declaring a stasher_file type. This is declaring an anonymous struct type and is creating a global instance named stasher_file.

What you intended was:

struct stasher_file {
 char name[32];
 int  size;
 int  start;
 int  popularity;
};

But note that while Brian R. Bondy's response wasn't correct about your error message, he's right that you're trying to write into the struct without having allocated space for it. If you want an array of pointers to struct stasher_file structures, you'll need to call malloc to allocate space for each one:

struct stasher_file *newFile = malloc(sizeof *newFile);
if (newFile == NULL) {
   /* Failure handling goes here. */
}
strncpy(newFile->name, name, 32);
newFile->size = size;
...

(BTW, be careful when using strncpy; it's not guaranteed to NUL-terminate.)

No, not exactly. But it can inherit from a class and implement one or more interfaces.

Clear terminology is important when discussing concepts like this. One of the things that you'll see mark out Jon Skeet's writing, for example, both here and in print, is that he is always precise in the way he decribes things.

For those who use com.nhaarman.mockitokotlin2.mock {}

This error occurs when, for example, we create a mock inside another mock

mock {
    on { x() } doReturn mock {
        on { y() } doReturn z()
    }
}

The solution to this is to create the child mock in a variable and use the variable in the scope of the parent mock to prevent the mock creation from being explicitly nested.

val liveDataMock = mock {
        on { y() } doReturn z()
}
mock {
    on { x() } doReturn liveDataMock
}
