Aquamacs:

(set-face-attribute 'default nil :font "Monaco-16" )

From the Emacs Wiki Globally Change the Default Font, it says you can use either of these:

(set-face-attribute 'default nil :font FONT )

(set-frame-font FONT nil t)

Where FONT is something like "Monaco-16", e.g.:

(set-face-attribute 'default nil :font "Monaco-16" )

There was an extra closing parenthesis in the first suggestion on the wiki, which caused an error on startup. I finally noticed the extra closing parenthesis, and I subsequently corrected the suggestion on the wiki. Then both of the suggestions worked for me.

Here's a similar system for the situation where you have a variable you want to sort by, initially, but then you want to sort by a secondary variable according to the order that this secondary variable first appears in the initial sort.

In the function below, the initial sort variable is called order_by and the secondary variable is called order_along - as in "order by this variable along its initial order".

library(dplyr, warn.conflicts = FALSE)
df <- structure(
  list(
    msoa11hclnm = c(
      "Bewbush", "Tilgate", "Felpham",
      "Selsey", "Brunswick", "Ratton", "Ore", "Polegate", "Mile Oak",
      "Upperton", "Arundel", "Kemptown"
    ),
    lad20nm = c(
      "Crawley", "Crawley",

    shape_area = c(

this does not give me what I need:

This example contains two files: Assembly1.cs and Assembly2.cs. The first file contains an internal base class, BaseClass. In the second file, an attempt to instantiate BaseClass will produce an error.

// Assembly1.cs
// compile with: /target:library
internal class BaseClass 
{
   public static int intM = 0;
}

// Assembly1_a.cs
// compile with: /reference:Assembly1.dll
class TestAccess 
{
   static void Main()
   {  
      BaseClass myBase = new BaseClass();   // CS0122
   }
}

In this example, use the same files you used in example 1, and change the accessibility level of BaseClass to public. Also change the accessibility level of the member IntM to internal. In this case, you can instantiate the class, but you cannot access the internal member.

// Assembly2.cs
// compile with: /target:library
public class BaseClass 
{
   internal static int intM = 0;
}

// Assembly2_a.cs
// compile with: /reference:Assembly1.dll
public class TestAccess 
{
   static void Main() 
   {      
      BaseClass myBase = new BaseClass();   // Ok.
      BaseClass.intM = 444;    // CS0117
   }
}

Use the zipfile module. To extract a file from a URL, you'll need to wrap the result of a urlopen call in a BytesIO object. This is because the result of a web request returned by urlopen doesn't support seeking:

from urllib.request import urlopen

from io import BytesIO
from zipfile import ZipFile

zip_url = 'http://example.com/my_file.zip'

with urlopen(zip_url) as f:
    with BytesIO(f.read()) as b, ZipFile(b) as myzipfile:
        foofile = myzipfile.open('foo.txt')
        print(foofile.read())

If you already have the file downloaded locally, you don't need BytesIO, just open it in binary mode and pass to ZipFile directly:

from zipfile import ZipFile

zip_filename = 'my_file.zip'

with open(zip_filename, 'rb') as f:
    with ZipFile(f) as myzipfile:
        foofile = myzipfile.open('foo.txt')
        print(foofile.read().decode('utf-8'))

Again, note that you have to open the file in binary ('rb') mode, not as text or you'll get a zipfile.BadZipFile: File is not a zip file error.

It's good practice to use all these things as context managers with the with statement, so that they'll be closed properly.

enum Enum{ Banana, Orange, Apple } ;
static const char * EnumStrings[] = { "bananas & monkeys", "Round and orange", "APPLE" };

const char * getTextForEnum( int enumVal )
{
  return EnumStrings[enumVal];
}

You can do something like

    SELECT *
      FROM (SELECT Fname FROM MyTbl ORDER BY Fname )
 WHERE rownum = 1;

You could also use the analytic functions RANK and/or DENSE_RANK, but ROWNUM is probably the easiest.

I just put together a nice data structure and chain of processing to generate this switching behaviour, no libraries needed. I'm sure it will have been implemented numerous times over, and came across this thread looking for examples - thought I'd chip in.

I didn't even particularly need flags (the only flag here is a debug mode, creating a variable which I check for as a condition of starting a downstream function if (!exists(debug.mode)) {...} else {print(variables)}). The flag checking lapply statements below produce the same as:

if ("--debug" %in% args) debug.mode <- T
if ("-h" %in% args || "--help" %in% args) 

where args is the variable read in from command line arguments (a character vector, equivalent to c('--debug','--help') when you supply these on for instance)

It's reusable for any other flag and you avoid all the repetition, and no libraries so no dependencies:

args <- commandArgs(TRUE)

flag.details <- list(
"debug" = list(
  def = "Print variables rather than executing function XYZ...",
  flag = "--debug",
  output = "debug.mode <- T"),
"help" = list(
  def = "Display flag definitions",
  flag = c("-h","--help"),
  output = "cat(help.prompt)") )

flag.conditions <- lapply(flag.details, function(x) {
  paste0(paste0('"',x$flag,'"'), sep = " %in% args", collapse = " || ")
})
flag.truth.table <- unlist(lapply(flag.conditions, function(x) {
  if (eval(parse(text = x))) {
    return(T)
  } else return(F)
}))

help.prompts <- lapply(names(flag.truth.table), function(x){
# joins 2-space-separatated flags with a tab-space to the flag description
  paste0(c(paste0(flag.details[x][[1]][['flag']], collapse="  "),
  flag.details[x][[1]][['def']]), collapse="\t")
} )

help.prompt <- paste(c(unlist(help.prompts),''),collapse="\n\n")

# The following lines handle the flags, running the corresponding 'output' entry in flag.details for any supplied
flag.output <- unlist(lapply(names(flag.truth.table), function(x){
  if (flag.truth.table[x]) return(flag.details[x][[1]][['output']])
}))
eval(parse(text = flag.output))

Note that in flag.details here the commands are stored as strings, then evaluated with eval(parse(text = '...')). Optparse is obviously desirable for any serious script, but minimal-functionality code is good too sometimes.

Sample output:

$ Rscript check_mail.Rscript --help
--debug Print  variables rather than executing function XYZ...

-h  --help  Display flag definitions

I faced this problem this morning when I just opened an old app with a different certificate and allowed its access to the keychain. My other app that was working pretty well, stopped working with this error. I've been pulling out my hair till now, when I simply did this:

Xcode Menu > Preferences > Accounts > THE_APPLE_ID_THAT_YOU_ARE_USING > View Details

In the new window, at the bottom left of the Signing identities press the + button and select iOS Development. It'll re-add the identity, and after that my problem is fixed now and the app is running on the device again.

public class Sam_Stringnth {

    public static void main(String[] args) {
        String str="abcabcabc";
        int n = nthsearch(str, 'c', 3);
        if(n<=0)
            System.out.println("Character not found");
        else
            System.out.println("Position is:"+n);
    }
    public static int nthsearch(String str, char ch, int n){
        int pos=0;
        if(n!=0){
            for(int i=1; i<=n;i++){
                pos = str.indexOf(ch, pos)+1;
            }
            return pos;
        }
        else{
            return 0;
        }
    }
}

"s" is not a "char*", it's a "char[4]". And so, "&s" is not a "char**", but actually "a pointer to an array of 4 characater". Your compiler may treat "&s" as if you had written "&s[0]", which is roughly the same thing, but is a "char*".

When you write "char** p = &s;" you are trying to say "I want p to be set to the address of the thing which currently points to "asd". But currently there is nothing which points to "asd". There is just an array which holds "asd";

char s[] = "asd";
char *p = &s[0];  // alternately you could use the shorthand char*p = s;
char **pp = &p;

Try This:

Select race_id, race_description
, Case patIndex ('%[ /-]%', LTrim (race_description))
    When 0 Then LTrim (race_description)
    Else substring (LTrim (race_description), 1, patIndex ('%[ /-]%', LTrim (race_description)) - 1)
End race_abbreviation

Another approach in 3.4 (don't know if this is proper Ext): You can have a delete handler like this, assuming every row has a 'delete' button.

handler: function(grid, rowIndex, colIndex) {
    var rec = grid.getStore().getAt(rowIndex);
    var id = rec.get('id');
    // some DELETE/GET ajax callback here...
    // pass in 'id' var or some key
    // inside success
    grid.getStore().removeAt(rowIndex);
}

I had also problems in finding something simple to satisfy my needs so I decided to write my own library (with MIT license). It's mainly based on composite and builder pattern.

A basic declarative example is:

import static com.github.manliogit.javatags.lang.HtmlHelper.*;

html5(attr("lang -> en"),
  head(
    meta(attr("http-equiv -> Content-Type", "content -> text/html; charset=UTF-8")),
    title("title"),
    link(attr("href -> xxx.css", "rel -> stylesheet"))
  )
).render();

A fluent example is:

ul()
  .add(li("item 1"))
  .add(li("item 2"))
  .add(li("item 3"))

I also created an on line converter to transform every html snippet (from complex bootstrap template to simple single snippet) on the fly (i.e. html -> javatags)

The TextInput has a TextFormatter which can be used to format, convert and limit the types of text that can be input.

The TextFormatter has a filter which can be used to reject input. We need to set this to reject anything that's not a valid integer. It also has a converter which we need to set to convert the string value to an integer value which we can bind later on.

Lets create a reusable filter:

public class IntegerFilter implements UnaryOperator<TextFormatter.Change> {
    private final static Pattern DIGIT_PATTERN = Pattern.compile("\\d*");

    @Override
    public Change apply(TextFormatter.Change aT) {
        return DIGIT_PATTERN.matcher(aT.getText()).matches() ? aT : null;
    }
}

The filter can do one of three things, it can return the change unmodified to accept it as it is, it can alter the change in some way it deems fit or it can return null to reject the change all together.

We will use the standard IntegerStringConverter as a converter.

Putting it all together we have:

TextField textField = ...;

TextFormatter<Integer> formatter = new TextFormatter<>(
    new IntegerStringConverter(), // Standard converter form JavaFX
    defaultValue, 
    new IntegerFilter());
formatter.valueProperty().bindBidirectional(myIntegerProperty);

textField.setTextFormatter(formatter);

If you want don't need a reusable filter you can do this fancy one-liner instead:

TextFormatter<Integer> formatter = new TextFormatter<>(
    new IntegerStringConverter(), 
    defaultValue,  
    c -> Pattern.matches("\\d*", c.getText()) ? c : null );

Make sure you are in the root drive. You will see something like this.

A super key is any combination of columns that uniquely identifies a row in a table. A candidate key is a super key which cannot have any columns removed from it without losing the unique identification property. This property is sometimes known as minimality or (better) irreducibility.

A super key ? a primary key in general. The primary key is simply a candidate key chosen to be the main key. However, in dependency theory, candidate keys are important and the primary key is not more important than any of the other candidate keys. Non-primary candidate keys are also known as alternative keys.

Consider this table of Elements:

CREATE TABLE elements
(
    atomic_number   INTEGER NOT NULL PRIMARY KEY
                    CHECK (atomic_number > 0 AND atomic_number < 120),
    symbol          CHAR(3) NOT NULL UNIQUE,
    name            CHAR(20) NOT NULL UNIQUE,
    atomic_weight   DECIMAL(8,4) NOT NULL,
    period          SMALLINT NOT NULL
                    CHECK (period BETWEEN 1 AND 7),
    group           CHAR(2) NOT NULL
                    -- 'L' for Lanthanoids, 'A' for Actinoids
                    CHECK (group IN ('1', '2', 'L', 'A', '3', '4', '5', '6',
                                     '7', '8', '9', '10', '11', '12', '13',
                                     '14', '15', '16', '17', '18')),
    stable          CHAR(1) DEFAULT 'Y' NOT NULL
                    CHECK (stable IN ('Y', 'N'))
);

It has three unique identifiers - atomic number, element name, and symbol. Each of these, therefore, is a candidate key. Further, unless you are dealing with a table that can only ever hold one row of data (in which case the empty set (of columns) is a candidate key), you cannot have a smaller-than-one-column candidate key, so the candidate keys are irreducible.

Consider a key made up of { atomic number, element name, symbol }. If you supply a consistent set of values for these three fields (say { 6, Carbon, C }), then you uniquely identify the entry for an element - Carbon. However, this is very much a super key that is not a candidate key because it is not irreducible; you can eliminate any two of the three fields without losing the unique identification property.

As another example, consider a key made up of { atomic number, period, group }. Again, this is a unique identifier for a row; { 6, 2, 14 } identifies Carbon (again). If it were not for the Lanthanoids and Actinoids, then the combination of { period, group } would be unique, but because of them, it is not. However, as before, atomic number on its own is sufficient to uniquely identify an element, so this is a super key and not a candidate key.

Add the template and give date pipe, you need to use escape characters for the format of the date. You can give any format as you want like 'MM-yyyy-dd' etc.

template: '{{ current_date | date: \'yyyy-MM-dd\' }}',

change does only work on input form elements.

you could just trigger a function after your XML / XSL transformation or make a listener:

var html = $('#laneconfigdisplay').html()
setInterval(function(){ if($('#laneconfigdisplay').html() != html){ alert('woo'); html = $('#laneconfigdisplay').html() } }, 10000) //checks your content box all 10 seconds and triggers alert when content has changed...

It is not certain that any global ECMAScript variables have been exported and html/css does not necessarily indicate React. So look in the .js.

Method 1: Look in ECMAScript:

The version number is exported by both modules react-dom and react but those names are often removed by bundling and the version hidden inside an execution context that cannot be accessed. A clever break point may reveal the value directly, or you can search the ECMAScript:

1. Load the Web page (you can try https://www.instagram.com they’re total Coolaiders)
2. Open Chrome Developer Tools on Sources tab (control+shift+i or command+shift+i)
   1. Dev tools open on the Sources tab
3. In the very right of the top menu bar, click the vertical ellipsis and select search all files
4. In he search box down on left type FIRED in capital letters, clear the checkbox Ignore case, type Enter
   1. One or more matches appear below. The version is an export very close to the search string looking like version: "16.0.0"
5. If the version number is not immediately visible: double click a line that begins with a line number
   1. ECMAScript appears in the middle pane
6. If the version number is not immediately visible: click the two braces at bottom left of the ECMAScript pane {}
   1. ECMAScript is reformatted and easier to read
7. If the version number is not immediately visible: scroll up and down a few lines to find it or try another search key
   1. If the code is not minified, search for ReactVersion There should be 2 hits with the same value
   2. If the code is minified, search for either SECRET_INTERNALS_DO_NOT_USE_OR_YOU_WILL_BE_FIRED or react-dom
   3. Or search for the likely version string itself: "15. or "16. or even "0.15

Method 2: Use a DOM breakpoint:

1. Load the page rendered by React
2. Right click a React element (anything, like an input field or a box) and select Inspect Element
   1. Chrome Developer Tools displays the Elements pane
3. As high up in the tree as possible from the selected element, but no higher than the React root element (often a div directly inside body with id root: <div id="root">), right click an element and select Break On… - subtree modifications
   1. Note: It is possible to compare contents of the Elements tab (DOM current state) with the response for the same resouce on the Networks tab. This may reveal React’s root element
4. Reload the page by clicking Reload left of the address bar
   1. Chrome Developer Tools stops at the breakpoint and displays the Sources pane
5. In the rightmost pane, examine the Call Stack sub-pane
6. As far down the call stack as possible, there should be a render entry, this is ReactDOM.render
7. Click the line below render, ie. the code that invokes render
8. The middle pane now displays ECMAScript with an expression containing .render highlighted
9. Hover the mouse cursor over the object used to invoke render, is. the react-dom module exports object
   1. if the code line goes: Object(u.render)(…, hover over the u
10. A tooltip window is displayed containing version: "15.6.2", ie. all values exported by react-dom

The version is also injected into React dev tools, but as far as I know not displayed anywhere.

you should use the break statement

usually it's use this way

$i = 0;
foreach($data as $key => $row){
    if(++$i > 2) break;
}

on the same fashion the continue statement exists if you need to skip some items.

YUI just recently added a utility specifically for this. See stylesheet.js here.

Usage of pip for installation of packages in Python 3

Step 1: Install Python 3. Yes, by default an application file pip3.exe is already located there in the path (E.g.):

C:/Users/name/AppData/Local/Programs/Python/Python36-32/Scripts

Step 2: Go to

>Control Panel (Local Machine) > System > Advanced system settings >

>Click on `Environment Variables` >
Set a New User Variable, for this click `New` >
Write new 'Variable name' as "PYTHON_SCRIPTS" >
Copy that path of `pip3.exe` and paste within variable value > `OK` >

>Below again find out and click on `Path` under 'system variables' >
Edit this path >
Within 'Variable value' append and paste the same path of `pip3.exe` after putting a ';' >
Click `OK`/`Apply` and come out.

Step 3: Now, open cmd bash/shell by Pressing key Windows+R.

> Write 'pip3' and press 'Enter'. If pip3 is recognized you can go ahead.

Step 4: In this same cmd

> Write path of the `pip3.exe` followed by `/pip install 'package name'`

As Example just write:

C:/Users/name/AppData/Local/Programs/Python/Python36-32/Scripts/pip install matplotlib

Press Enter now. The Package matplotlib will start getting downloaded.

Further, for upgrading any package

Open cmd bash/shell again, then

type that path of pip3.exe followed by /pip install --upgrade 'package name' Press Enter.

As Example just write:

C:/Users/name/AppData/Local/Programs/Python/Python36-32/Scripts/pip install --upgrade matplotlib

Upgrading of the package will start :)

public enum Tax {

NONE(1), SALES(2), IMPORT(3);

private final int value;
    private Tax(int value) {
        this.value = value;
    }

    public String toString() {
        return Integer.toString(value);
    }
}

class Test {
    System.out.println(Tax.NONE);    //Just an example.
}

use the code
cell.setCellType(Cell.CELL_TYPE_STRING);
before reading the string value, Which can help you.
I am using POI version 3.17 Beta1 version, sure the version compatibility also..

Why do you not use the java functionality for that:

If your numbers are small (smaller than yours) you could use: Integer.parseInt(hex, 16) to convert a Hex - String into an integer.

  String hex = "ff"
  int value = Integer.parseInt(hex, 16);  

For big numbers like yours, use public BigInteger(String val, int radix)

  BigInteger value = new BigInteger(hex, 16);

@See JavaDoc:

• Integer.parseInt(String value, int radix)
• BigInteger(String value, int radix)

Main advantage for me is that Sublime Text 2 is almost the same, and has the same features on Windows, Linux and OS X. Can you claim that about Notepad++? It makes me move from one OS to another seamlessly.

Then there is speed. Sublime Text 2, which people claim is buggy and unstable ( 3 is more stable ), is still amazingly fast. If you use it, you will realize how fast it is.

Sublime Text 2 has some neat features like multi cursor input, multiple selections etc that will make you immensely productive.

Good number of plugins and themes, and also support for those of Textmate means you can do anything with Sublime Text 2. I have moved from Notepad++ to Sublime Text 2 on Windows and haven't looked back. The real question for me has been - Sublime Text 2 or vim?

What's good on Notepad++ side - it loads much faster on Windows for me. Maybe it will be good enough for you for quick editing. But, again, Sublime Text 3 is supposed to be faster on this front too. Sublime text 2 is not really good when it comes to handling huge files, and I had found that Notepad++ was pretty good till certain size of files. And, of course, Notepad++ is free. Sublime Text 2 has unlimited trial.

This issue can also raise when you change your system password but not the same updated on your .npmrc file that exist on path C:\Users\user_name, so update your password there too.

please check on it and run npm install first and then npm start.

The accepted answer works for most cases, but it doesn't work well when your div can vary greatly in height — the animation speed is not dependent on the actual height of the content, and it can look choppy.

You can still perform the actual animation with CSS, but you need to use JavaScript to compute the height of the items, instead of trying to use auto. No jQuery is required, although you may have to modify this a bit if you want compatibility (works in the latest version of Chrome :)).

window.toggleExpand = function(element) {_x000D_
    if (!element.style.height || element.style.height == '0px') { _x000D_
        element.style.height = Array.prototype.reduce.call(element.childNodes, function(p, c) {return p + (c.offsetHeight || 0);}, 0) + 'px';_x000D_
    } else {_x000D_
        element.style.height = '0px';_x000D_
    }_x000D_
}

#menu #list {_x000D_
    height: 0px;_x000D_
    transition: height 0.3s ease;_x000D_
    background: #d5d5d5;_x000D_
    overflow: hidden;_x000D_
}

<div id="menu">_x000D_
    <input value="Toggle list" type="button" onclick="toggleExpand(document.getElementById('list'));">_x000D_
    <ul id="list">_x000D_

The '\r' character is the carriage return, and the carriage return-newline pair is both needed for newline in a network virtual terminal session.

From the old telnet specification (RFC 854) (page 11):

The sequence "CR LF", as defined, will cause the NVT to be positioned at the left margin of the next print line (as would, for example, the sequence "LF CR").

However, from the latest specification (RFC5198) (page 13):

1. ...

2. In Net-ASCII, CR MUST NOT appear except when immediately followed by either NUL or LF, with the latter (CR LF) designating the "new line" function. Today and as specified above, CR should generally appear only when followed by LF. Because page layout is better done in other ways, because NUL has a special interpretation in some programming languages, and to avoid other types of confusion, CR NUL should preferably be avoided as specified above.

3. LF CR SHOULD NOT appear except as a side-effect of multiple CR LF sequences (e.g., CR LF CR LF).

So newline in Telnet should always be '\r\n' but most implementations have either not been updated, or keeps the old '\n\r' for backwards compatibility.

Exe Application, first of all, references from a current directory to a subdirectory. And then, system directory. VS6.0 system directory was ..windows/system32. .NET system directory is like the below GAC path.

1. GAC path

   1) C:\Windows\Assembly (for .NET 2.0 ~ 3.5)

   2) C:\Windows\Microsoft.NET\assembly (for .NET 4.0)

2. How to install an assembly into GAC (as Administrator)

   1) Drag and Drop

   2) Use GacUtil.exe with Visual Studio Command Prompt

    gacutil -i [Path][Assembly Name].dll
   

   • Note: To install an assembly into the GAC, the assembly must be strongly named. Otherwise you get an error like this: Failure adding assembly to the cache: Attempt to install an assembly without a strong name.

3. How to uninstall an assembly from GAC (as Administrator)

    gacutil -u [Assembly Name], Version=1.0.0.0, PublickeyToken=7896a3567gh
   

   • Note: has no extention, .dll. Version and PublickeyToken can be omitted and be checked in GAC assembly.

It can be easily done by:

set.seed(101) # Set Seed so that same sample can be reproduced in future also
# Now Selecting 75% of data as sample from total 'n' rows of the data  
sample <- sample.int(n = nrow(data), size = floor(.75*nrow(data)), replace = F)
train <- data[sample, ]
test  <- data[-sample, ]

By using caTools package:

require(caTools)
set.seed(101) 
sample = sample.split(data$anycolumn, SplitRatio = .75)
train = subset(data, sample == TRUE)
test  = subset(data, sample == FALSE)

There's now a much simpler solution than when this question was originally asked, five years ago. A CSS Flexbox makes the two column layout originally asked for easy. This is the bare bones equivalent of the table in the original question:

<div style="display: flex">
    <div>AAA</div>
    <div>BBB</div>
</div>

One of the nice things about a Flexbox is that it lets you easily specify how child elements should shrink and grow to adjust to the container size. I will expand on the above example to make the box the full width of the page, make the left column a minimum of 75px wide, and grow the right column to capture the leftover space. I will also pull the style into its own proper block, assign some background colors so that the columns are apparent, and add legacy Flex support for some older browsers.

<style type="text/css">
.flexbox {
    display: -ms-flex;
    display: -webkit-flex;
    display: flex;
    width: 100%;
}

.left {
    background: #a0ffa0;
    min-width: 75px;
    flex-grow: 0;
}

.right {
    background: #a0a0ff;
    flex-grow: 1;
}
</style>

...

<div class="flexbox">
    <div class="left">AAA</div>
    <div class="right">BBB</div>
</div>

Flex is relatively new, and so if you're stuck having to support IE 8 and IE 9 you can't use it. However, as of this writing, http://caniuse.com/#feat=flexbox indicates at least partial support by browsers used by 94.04% of the market.

The only way UTF-8 affects std::string is that size(), length(), and all the indices are measured in bytes, not characters.

And, as sbi points out, incrementing the iterator provided by std::string will step forward by byte, not by character, so it can actually point into the middle of a multibyte UTF-8 codepoint. There's no UTF-8-aware iterator provided in the standard library, but there are a few available on the 'Net.

If you remember that, you can put UTF-8 into std::string, write it to a file, etc. all in the usual way (by which I mean the way you'd use a std::string without UTF-8 inside).

You may want to start your file with a byte order mark so that other programs will know it is UTF-8.

This mistake i was doing is i was passing the whole url in domain attribute, it should be only domain name.

let cookie = HTTPCookie(properties: [
.domain: "example.com",
.path: "/",
.name: "MyCookieName",
.value: "MyCookieValue",
.secure: "TRUE",
])! 

webView.configuration.websiteDataStore.httpCookieStore.setCookie(cookie)

function GetURLParameter(parameter) {
        var url;
        var search;
        var parsed;
        var count;
        var loop;
        var searchPhrase;
        url = window.location.href;
        search = url.indexOf("?");
        if (search < 0) {
            return "";
        }
        searchPhrase = parameter + "=";
        parsed = url.substr(search+1).split("&");
        count = parsed.length;
        for(loop=0;loop<count;loop++) {
            if (parsed[loop].substr(0,searchPhrase.length)==searchPhrase) {
                return decodeURI(parsed[loop].substr(searchPhrase.length));
            }
        }
        return "";
    }

Oracle's installer puts java inside the /Library/Internet Plug-Ins/JavaAppletPlugin.plugin. And it doesn't overwrite /usr/bin/java. So, if you issue a

whereis java

in the terminal, it'll return /usr/bin/java. (which in turn points to /System/Library/Frameworks/JavaVM.framework/Versions/A/Commands/java, which is Apple's 1.6 version).

So, if you want to use the new java version, replace the /usr/bin/java symlink so that it points to /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java instead:

sudo rm /usr/bin/java
sudo ln -s /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java /usr/bin

Since you mentioned you use a proxy, try setting up the firefox driver with a proxy by following the answer given here proxy selenium python firefox

If you want to redirect from some location to subdomain you can use:

Redirect 301 /Old-Location/ http://subdomain.yourdomain.com

To add the solution I found to this problem when I had it, I was including a class from another file and the file I tried to instantiate it in gave the "not a constructor" error. Ultimately the issue was a couple unused requires in the other file before the class was defined. I'm not sure why they broke it, but removing them fixed it. Always be sure to check if something might be hiding in between the steps you're thinking about.

Check this out. The author provides a simple but elegant solution which doesn't require any 3rd party library. http://www.ksmpartners.com/2013/08/nicely-formatted-tabular-output-in-java/

you can try with

document.getElementById('btn').disabled = !this.checked"

<input type="submit" name="btn"  id="btn" value="submit" disabled/>_x000D_
_x000D_
<input type="checkbox"  onchange="document.getElementById('btn').disabled = !this.checked"/>

1. Connection pooling is handled as in any other ADO.NET application. Entity connection still uses traditional database connection with traditional connection string. I believe you can turn off connnection pooling in connection string if you don't want to use it. (read more about SQL Server Connection Pooling (ADO.NET))
2. Never ever use global context. ObjectContext internally implements several patterns including Identity Map and Unit of Work. Impact of using global context is different per application type.
3. For web applications use single context per request. For web services use single context per call. In WinForms or WPF application use single context per form or per presenter. There can be some special requirements which will not allow to use this approach but in most situation this is enough.

If you want to know what impact has single object context for WPF / WinForm application check this article. It is about NHibernate Session but the idea is same.

Edit:

When you use EF it by default loads each entity only once per context. The first query creates entity instace and stores it internally. Any subsequent query which requires entity with the same key returns this stored instance. If values in the data store changed you still receive the entity with values from the initial query. This is called Identity map pattern. You can force the object context to reload the entity but it will reload a single shared instance.

Any changes made to the entity are not persisted until you call SaveChanges on the context. You can do changes in multiple entities and store them at once. This is called Unit of Work pattern. You can't selectively say which modified attached entity you want to save.

Combine these two patterns and you will see some interesting effects. You have only one instance of entity for the whole application. Any changes to the entity affect the whole application even if changes are not yet persisted (commited). In the most times this is not what you want. Suppose that you have an edit form in WPF application. You are working with the entity and you decice to cancel complex editation (changing values, adding related entities, removing other related entities, etc.). But the entity is already modified in shared context. What will you do? Hint: I don't know about any CancelChanges or UndoChanges on ObjectContext.

I think we don't have to discuss server scenario. Simply sharing single entity among multiple HTTP requests or Web service calls makes your application useless. Any request can just trigger SaveChanges and save partial data from another request because you are sharing single unit of work among all of them. This will also have another problem - context and any manipulation with entities in the context or a database connection used by the context is not thread safe.

Even for a readonly application a global context is not a good choice because you probably want fresh data each time you query the application.

Just to help anyone coming to this page. This is an alternate if you are flexible with using some other icon library.

James is correct that you cannot change the font weight however if you are looking for more modern look for icons then you might consider ionicons

It has both ios and android versions for icons.

UPDATE

While these methods work, newer versions of VS Code uses the Ctrl+] shortcut to indent a block of code once, and Ctrl+[ to remove indentation.

This method detects the indentation in a file and indents accordingly.You can change the size of indentation by clicking on the Select Indentation setting in the bottom right of VS Code (looks something like "Spaces: 2"), selecting "Indent using Spaces" from the drop-down menu and then selecting by how many spaces you would like to indent.

Methods that use isNaN do not work if you're trying to use parseInt, for example:

parseInt("abc"); // NaN
parseInt(""); // NaN
parseInt("14px"); // 14

But in the second case isNaN produces false (i.e. the null string is a number)

n="abc"; isNaN(n) ? 0 : parseInt(n); // 0
n=""; isNaN(n) ? 0: parseInt(n); // NaN
n="14px"; isNaN(n) ? 0 : parseInt(n); // 14

In summary, the null string is considered a valid number by isNaN but not by parseInt. Verified with Safari, Firefox and Chrome on OSX Mojave.

Assuming line of best fit for a set of points is:

y = a + b * x

b = ( sum(xi * yi) - n * xbar * ybar ) / sum((xi - xbar)^2)
a = ybar - b * xbar

Code and plot

# sample points 
X = [0, 5, 10, 15, 20]
Y = [0, 7, 10, 13, 20]

# solve for a and b
def best_fit(X, Y):

    xbar = sum(X)/len(X)
    ybar = sum(Y)/len(Y)
    n = len(X) # or len(Y)

    numer = sum([xi*yi for xi,yi in zip(X, Y)]) - n * xbar * ybar
    denum = sum([xi**2 for xi in X]) - n * xbar**2

    b = numer / denum
    a = ybar - b * xbar

    print('best fit line:\ny = {:.2f} + {:.2f}x'.format(a, b))

    return a, b

# solution
a, b = best_fit(X, Y)
#best fit line:
#y = 0.80 + 0.92x

# plot points and fit line
import matplotlib.pyplot as plt
plt.scatter(X, Y)
yfit = [a + b * xi for xi in X]
plt.plot(X, yfit)

UPDATE:

notebook version

Here's a solt. that checks for no data

var someStr = 'abc'; // add 123 to string to see inverse

var thenum = someStr.match(/\d+/);

if (thenum != null )
{
    console.log(thenum[0]);
}
else
{
 console.log('no number');
}

If you are implicitly declaring the variable without var, the proper way would be to use delete foo.

However after you delete it, if you try to use this in an operation such as addition a ReferenceError will be thrown because you can't add a string to an undeclared, undefined identifier. Example:

x = 5;
delete x
alert('foo' + x )
// ReferenceError: x is not defined

It may be safer in some situations to assign it to false, null, or undefined so it's declared and won't throw this type of error.

foo = false

Note that in ECMAScript null, false, undefined, 0, NaN, or '' would all evaluate to false. Just make sure you dont use the !== operator but instead != when type checking for booleans and you don't want identity checking (so null would == false and false == undefined).

Also note that delete doesn't "delete" references but just properties directly on the object, e.g.:

bah = {}, foo = {}; bah.ref = foo;

delete bah.ref;
alert( [bah.ref, foo ] )
// ,[object Object] (it deleted the property but not the reference to the other object)

If you have declared a variable with var you can't delete it:

(function() {
    var x = 5;
    alert(delete x)
    // false
})();

In Rhino:

js> var x
js> delete x
false

Nor can you delete some predefined properties like Math.PI:

js> delete Math.PI
false

There are some odd exceptions to delete as with any language, if you care enough you should read:

• https://developer.mozilla.org/en/Core_JavaScript_1.5_Reference/Operators/Special_Operators/delete_Operator
• http://www.ecma-international.org/publications/files/ECMA-ST/ECMA-262.pdf

None of these solutions worked for me since I wanted to find peaks in the center of repeating values as well. for example, in

ar = np.array([0,1,2,2,2,1,3,3,3,2,5,0])

the answer should be

array([ 3,  7, 10], dtype=int64)

I did this using a loop. I know it's not super clean, but it gets the job done.

def findLocalMaxima(ar):
# find local maxima of array, including centers of repeating elements    
maxInd = np.zeros_like(ar)
peakVar = -np.inf
i = -1
while i < len(ar)-1:
#for i in range(len(ar)):
    i += 1
    if peakVar < ar[i]:
        peakVar = ar[i]
        for j in range(i,len(ar)):
            if peakVar < ar[j]:
                break
            elif peakVar == ar[j]:
                continue
            elif peakVar > ar[j]:
                peakInd = i + np.floor(abs(i-j)/2)
                maxInd[peakInd.astype(int)] = 1
                i = j
                break
    peakVar = ar[i]
maxInd = np.where(maxInd)[0]
return maxInd 

Set following php parameters to same value in seconds:

session.gc_maxlifetime

in php.ini, .htaccess or for example with

for a day.

You could also write up your own user functions to handle dates in the format you choose. SQLite has a fairly simple method for writing your own user functions. For example, I wrote a few to add time durations together.

It will give the current location.

mMap.setMyLocationEnabled(true);
Location userLocation = mMap.getMyLocation();
        LatLng myLocation = null;
        if (userLocation != null) {
            myLocation = new LatLng(userLocation.getLatitude(),
                    userLocation.getLongitude());
            mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(myLocation,
                    mMap.getMaxZoomLevel()-5));

Try using in like this:

>>> x = 'hello'
>>> y = 'll'
>>> y in x
True

UPDATE `your_table` SET 

`something` = IF(`id`="1","new_value1",`something`), `smth2` = IF(`id`="1", "nv1",`smth2`),
`something` = IF(`id`="2","new_value2",`something`), `smth2` = IF(`id`="2", "nv2",`smth2`),
`something` = IF(`id`="4","new_value3",`something`), `smth2` = IF(`id`="4", "nv3",`smth2`),
`something` = IF(`id`="6","new_value4",`something`), `smth2` = IF(`id`="6", "nv4",`smth2`),
`something` = IF(`id`="3","new_value5",`something`), `smth2` = IF(`id`="3", "nv5",`smth2`),
`something` = IF(`id`="5","new_value6",`something`), `smth2` = IF(`id`="5", "nv6",`smth2`) 

// You just building it in php like

$q = 'UPDATE `your_table` SET ';

foreach($data as $dat){

  $q .= '

       `something` = IF(`id`="'.$dat->id.'","'.$dat->value.'",`something`), 
       `smth2` = IF(`id`="'.$dat->id.'", "'.$dat->value2.'",`smth2`),';

}

$q = substr($q,0,-1);

So you can update hole table with one query

Use rm symlinkname but do not include a forward slash at the end (do not use: rm symlinkname/). You will then be asked if you want to remove the symlink, y to answer yes.

I'm adding this answer not because it's likely to be helpful but just because it's true.

In addition to using the existing answers explaining how to make more than one translation by chaining them, you can also construct the 4x4 matrix yourself

I grabbed the following image from some random site I found while googling which shows rotational matrices:

Rotation around x axis:
Rotation around y axis:
Rotation around z axis:

I couldn't find a good example of translation, so assuming I remember/understand it right, translation:

[1 0 0 0]
[0 1 0 0]
[0 0 1 0]
[x y z 1]

See more at the Wikipedia article on transformation as well as the Pragamatic CSS3 tutorial which explains it rather well. Another guide I found which explains arbitrary rotation matrices is Egon Rath's notes on matrices

Matrix multiplication works between these 4x4 matrices of course, so to perform a rotation followed by a translation, you make the appropriate rotation matrix and multiply it by the translation matrix.

This can give you a bit more freedom to get it just right, and will also make it pretty much completely impossible for anyone to understand what it's doing, including you in five minutes.

But, you know, it works.

Edit: I just realized that I missed mentioning probably the most important and practical use of this, which is to incrementally create complex 3D transformations via JavaScript, where things will make a bit more sense.

You can map() arrays, but there is no such operation for Maps. The solution from Dr. Axel Rauschmayer:

• Convert the map into an array of [key,value] pairs.
• Map or filter the array.
• Convert the result back to a map.

Example:

let map0 = new Map([
  [1, "a"],
  [2, "b"],
  [3, "c"]
]);

const map1 = new Map(
  [...map0]
  .map(([k, v]) => [k * 2, '_' + v])
);

resulted in

{2 => '_a', 4 => '_b', 6 => '_c'}

You can use method reference like this:

user.ifPresent(ClassNameWhereMethodIs::doSomethingWithUser);

Method ifPresent() get Consumer object as a paremeter and (from JavaDoc): "If a value is present, invoke the specified consumer with the value." Value it is your variable user.

Or if this method doSomethingWithUser is in the User class and it is not static, you can use method reference like this:

user.ifPresent(this::doSomethingWithUser);

From the help (if /?):

The ELSE clause must occur on the same line as the command after the IF.  For
example:

    IF EXIST filename. (
        del filename.
    ) ELSE (
        echo filename. missing.
    )

The following would NOT work because the del command needs to be terminated
by a newline:

    IF EXIST filename. del filename. ELSE echo filename. missing

Nor would the following work, since the ELSE command must be on the same line
as the end of the IF command:

    IF EXIST filename. del filename.
    ELSE echo filename. missing

The <ul> element has browser inherent padding & margin by default. In your case, Use

#footer ul {
    margin: 0; /* To remove default bottom margin */ 
    padding: 0; /* To remove default left padding */
}

or a CSS browser reset ( https://cssreset.com/ ) to deal with this.

While I am no Objective-C expert, I personally just define the method in the implementation of my class. Granted, it must be defined before (above) any methods calling it, but it definitely takes the least amount of work to do.

If deploying to Azure and you get this error. Simply delete all files on the site (backup any web.config, appsettings.json or whatver you do not want to loose) and deploy again. There are some left over dll files that should not be on the site, that makes the Azure portal think it needs to use OWIN.

Hope this helps! You can find code here.

from sys import exit
exit()

As a parameter you can pass an exit code, which will be returned to OS. Default is 0.

The existing answers show a possible solution for single files or file types. However, you can define the charset standard in VS Code by following this path:

File > Preferences > Settings > Encoding > Choose your option

This will define a character set as default. Besides that, you can always change the encoding in the lower right corner of the editor (blue symbol line) for the current project.

NULL is a value that is valid for any pointer type. It represents the absence of a value.

A void pointer is a type. Any pointer type is convertible to a void pointer hence it can point to any value. This makes it good for general storage but bad for use. By itself it cannot be used to access a value. The program must have extra context to understand the type of value the void pointer refers to before it can access the value.

If the value of a disabled textbox needs to be retained when a form is cleared (reset), disabled = "disabled" has to be used, as read-only textbox will not retain the value

For Example:

HTML

Textbox

<input type="text" id="disabledText" name="randombox" value="demo" disabled="disabled" />

Reset button

<button type="reset" id="clearButton">Clear</button>

In the above example, when Clear button is pressed, disabled text value will be retained in the form. Value will not be retained in the case of input type = "text" readonly="readonly"

It should be

if (*message == '\0')

In C, simple quotes delimit a single character whereas double quotes are for strings.

If time_created is a unix timestamp (int), you should be able to use something like this:

DELETE FROM locks WHERE time_created < (UNIX_TIMESTAMP() - 600);

(600 seconds = 10 minutes - obviously)

Otherwise (if time_created is mysql timestamp), you could try this:

DELETE FROM locks WHERE time_created < (NOW() - INTERVAL 10 MINUTE)

try using -U (aka --update-snapshots) when you run maven

And make sure the dependency definition is correct

I think I found it. All you have to do is type in "`n" (WITH THE QUOTATION MARKS!)

Thanks!

comboBox1.SelectedItem = MyEnum.Something;

should work just fine ... How can you tell that SelectedItem is null?

This function will return a converted SQL date from java date object.

public java.sql.Date convertJavaDateToSqlDate(java.util.Date date) {

}

In order to keep both versions, I just changed the value of PATH environment variable by putting the new version's git path "/usr/local/git/bin/" at the beginning, it forces to use the newest version:

$ echo $PATH

/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin:/usr/local/git/bin/

$ git --version

git version 2.4.9 (Apple Git-60)

original value: /usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin:/usr/local/git/bin/

new value: /usr/local/git/bin/:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin

$ export PATH=/usr/local/git/bin/:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin

$ git --version

git version 2.13.0

It's an old question, but I found this can be done easily with Spacy. Once the document is read, a simple api similarity can be used to find the cosine similarity between the document vectors.

import spacy
nlp = spacy.load('en')
doc1 = nlp(u'Hello hi there!')
doc2 = nlp(u'Hello hi there!')
doc3 = nlp(u'Hey whatsup?')

print doc1.similarity(doc2) # 0.999999954642
print doc2.similarity(doc3) # 0.699032527716
print doc1.similarity(doc3) # 0.699032527716

Prerequisite

using System.Linq;

then ...

string res = string.Join(Environment.NewLine, 
    results.Rows.OfType<DataRow>().Select(x => string.Join(" ; ", x.ItemArray)));

PHP-FPM is a service that spawns new PHP processes when needed, usually through a fast-cgi module like nginx. You can tell (with a margin of error) by just checking the init.d script e.g. "sudo /etc/init.d/php-fpm status"

What port or unix file socket is being used is up to the configuration, but often is just TCP port 9000. i.e. 127.0.0.1:9000

The best way to tell if it is running correctly is to have nginx running, and setup a virtual host that will fast-cgi pass to PHP-FPM, and just check it with wget or a browser.

You have misunderstood :hover; it says the mouse is over an item, rather than the mouse has just entered the item.

You could add animation to the selector without :hover to achieve the effect you want.

Transitions is a better option: http://jsfiddle.net/Cvx96/

This will do what you want:

select * 
  from orders_products 
       INNER JOIN orders 
          ON orders_products.orders_id = orders.orders_id
 where products_id in (180, 181);

There are several issues:

1. elif option == 2: and the subsequent elif-else should be aligned with the second if option == 1, not with the for.

2. The for x in range(x, 1, 1): is missing a body.

3. Since "option 1 (count)" requires a second input, you need to call input() for the second time. However, for sanity's sake I urge you to store the result in a second variable rather than repurposing option.

4. The comparison in the first line of your code is probably meant to be an assignment.

You'll discover more issues once you're able to run your code (you'll need a couple more input() calls, one of the range() calls will need attention etc).

Lastly, please don't use the same variable as the loop variable and as part of the initial/terminal condition, as in:

            for x in range(1, x, 1):
                print x

It may work, but it is very confusing to read. Give the loop variable a different name:

            for i in range(1, x, 1):
                print i

using DotNetZip (available as nuget package):

public void Zip(string source, string destination)
{
    using (ZipFile zip = new ZipFile
    {
        CompressionLevel = CompressionLevel.BestCompression
    })
    {
        var files = Directory.GetFiles(source, "*",
            SearchOption.AllDirectories).
            Where(f => Path.GetExtension(f).
                ToLowerInvariant() != ".zip").ToArray();

        foreach (var f in files)
        {
            zip.AddFile(f, GetCleanFolderName(source, f));
        }

        var destinationFilename = destination;

        if (Directory.Exists(destination) && !destination.EndsWith(".zip"))
        {
            destinationFilename += $"\\{new DirectoryInfo(source).Name}-{DateTime.Now:yyyy-MM-dd-HH-mm-ss-ffffff}.zip";
        }

        zip.Save(destinationFilename);
    }
}

private string GetCleanFolderName(string source, string filepath)
{
    if (string.IsNullOrWhiteSpace(filepath))
    {
        return string.Empty;
    }

    var result = filepath.Substring(source.Length);

    if (result.StartsWith("\\"))
    {
        result = result.Substring(1);
    }

    result = result.Substring(0, result.Length - new FileInfo(filepath).Name.Length);

    return result;
}

Usage:

Zip(@"c:\somefolder\subfolder\source", @"c:\somefolder2\subfolder2\dest");

Or

Zip(@"c:\somefolder\subfolder\source", @"c:\somefolder2\subfolder2\dest\output.zip");

Based on the above post i tried this and this worked fine I wanted to use the value of Map B as keys for Map A:

<c:if test="${not empty activityCodeMap and not empty activityDescMap}">
<c:forEach var="valueMap" items="${auditMap}">
<tr>
<td class="activity_white"><c:out value="${activityCodeMap[valueMap.value.activityCode]}"/></td>
<td class="activity_white"><c:out value="${activityDescMap[valueMap.value.activityDescCode]}"/></td>
<td class="activity_white">${valueMap.value.dateTime}</td>
</tr>
</c:forEach>
</c:if>

Positional Arguments

They have no keywords before them. The order is important!

func(1,2,3, "foo")

Keyword Arguments

They have keywords in the front. They can be in any order!

func(foo="bar", baz=5, hello=123)

func(baz=5, foo="bar", hello=123)

You should also know that if you use default arguments and neglect to insert the keywords, then the order will then matter!

def func(foo=1, baz=2, hello=3): ...
func("bar", 5, 123)

You can embed HTML in Markdown, so you can do something like this:

<img style="float: right;" src="whatever.jpg">

Continue markdown text...

This way worked for me:

adding the path that you like:

export PYTHONPATH=$PYTHONPATH:/path/you/want/to/add

checking: you can run 'export' cmd and check the output or you can check it using this cmd:

python -c "import sys; print(sys.path)"

package name with 0 may cause problem for sharedPreference.

(OK) con = createPackageContext("com.example.android.sf1", 0);

(Problem but no error)

con = createPackageContext("com.example.android.sf01", 0);

The lean option tells Mongoose to skip hydrating the result documents. This makes queries faster and less memory intensive, but the result documents are plain old JavaScript objects (POJOs), not Mongoose documents.

const leanDoc = await MyModel.findOne().lean();

not necessary to use JSON.parse() method

Another solution is to use stat_count() when dealing with discrete variables (and stat_bin() with continuous ones).

ggplot(data = df, aes(x = x)) +
geom_bar(stat = "count") + 
stat_count(geom = "text", colour = "white", size = 3.5,
aes(label = ..count..),position=position_stack(vjust=0.5))

For the sake of snippet of what the guys have explained above:

import socket
from contextlib import closing

def find_free_port():
    with closing(socket.socket(socket.AF_INET, socket.SOCK_STREAM)) as s:
        s.bind(('', 0))
        s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
        return s.getsockname()[1]

For storing a single row output into a variable from the select into query :

declare v_username varchare(20); SELECT username into v_username FROM users WHERE user_id = '7';

this will store the value of a single record into the variable v_username.

For storing multiple rows output into a variable from the select into query :

you have to use listagg function. listagg concatenate the resultant rows of a coloumn into a single coloumn and also to differentiate them you can use a special symbol. use the query as below SELECT listagg(username || ',' ) within group (order by username) into v_username FROM users;

this will help all of you to find your own correct details use

npm ls dist-tag

this will then show the correct info so you don't guess the version file location etc

enjoy :)

Similar to the above answer, but written differently.

$.extend(
{
    redirectPost: function (location, args) {
        var form = $('<form>', { action: location, method: 'post' });
        $.each(args,
            function (key, value) {
                $(form).append(
                    $('<input>', { type: 'hidden', name: key, value: value })
                );
            });
        $(form).appendTo('body').submit();
    }
});

You should create the response using Request.CreateResponse:

HttpResponseMessage response =  Request.CreateResponse(HttpStatusCode.BadRequest, "Error message");

You can pass objects not just strings to CreateResponse and it will serialize them based on the request's Accept header. This saves you from manually choosing a formatter.

If you want to see output logs from all the services in your terminal.

docker-compose logs -t -f --tail <no of lines> 

Eg.: Say you would like to log output of last 5 lines from all service

docker-compose logs -t -f --tail 5

If you wish to log output from specific services then it can be done as below:

docker-compose logs -t -f --tail <no of lines> <name-of-service1> <name-of-service2> ... <name-of-service N>

Usage:

Eg. say you have API and portal services then you can do something like below :

docker-compose logs -t -f --tail 5 portal api

Where 5 represents last 5 lines from both logs.

Ref: https://docs.docker.com/v17.09/engine/admin/logging/view_container_logs/

I got the solution for onunload in all browsers except Opera by changing the Ajax asynchronous request into synchronous request.

xmlhttp.open("POST","LogoutAction",false);

It works well for all browsers except Opera.

It's better to use the actual (msi) installer from nodejs.org instead of downloading the node executable only. The installer includes npm and makes it easier to manage your node installation. There is an installer for both 32-bit and 64-bit Windows.

Also a couple of other tidbits:

• Installing modules globally doesn't do what you might expect. The only modules you should install globally (the -g flag in npm) are ones that install commands. So to install Express you would just do npm install express and that will install Express to your current working directory. If you were instead looking for the Express project generator (command), you need to do npm install -g express-generator for Express 4.

• You can use node anywhere from your command prompt to execute scripts. For example if you have already written a separate script: node foo.js. Or you can open up the REPL (as you've already found out) by just selecting the node.js (start menu) shortcut or by just typing node in a command prompt.

you have to add the property Tables to the DataGridView Data Source

 dataGridView1.DataSource = table.Tables[0];

According to the documentation of the Item property:

Sets or returns an item for a specified key in a Dictionary object.

In your case, you don't have an item whose key is 1 so doing:

s = d.Item(i)

actually creates a new key / value pair in your dictionary, and the value is empty because you have not used the optional newItem argument.

The Dictionary also has the Items method which allows looping over the indices:

a = d.Items
For i = 0 To d.Count - 1
    s = a(i)
Next i

For method decorator declaration with configuration "noImplicitAny": true, you can specify type of this variable explicitly depends on @tony19's answer

function logParameter(this:any, target: Object, propertyName: string) {
  //...
}

From the documentation:

Named exports are useful to export several values. During the import, one will be able to use the same name to refer to the corresponding value.

Concerning the default export, there is only a single default export per module. A default export can be a function, a class, an object or anything else. This value is to be considered as the "main" exported value since it will be the simplest to import.

In java-8, they introduced the method removeIf which takes a Predicate as parameter.

So it will be easy as:

List<String> list = new ArrayList<>(Arrays.asList("How are you",
                                                  "How you doing",
                                                  "Joe",
                                                  "Mike"));
list.removeIf(s -> !s.contains("How"));

This is probably the easiest way, not the prettiest though:

SELECT *,
    (SELECT Count(*) FROM eventsTable WHERE columnName = 'Business') as RowCount
    FROM eventsTable
    WHERE columnName = 'Business'

This will also work without having to use a group by

SELECT *, COUNT(*) OVER () as RowCount
    FROM eventsTables
    WHERE columnName = 'Business'

"Stack Me 123 Heppa1 oeu".toCharArray() ?

If you know the text in the combo box that you want to select, just use the setCurrentText() method to select that item.

ui->comboBox->setCurrentText("choice 2");

From the Qt 5.7 documentation

The setter setCurrentText() simply calls setEditText() if the combo box is editable. Otherwise, if there is a matching text in the list, currentIndex is set to the corresponding index.

So as long as the combo box is not editable, the text specified in the function call will be selected in the combo box.

Reference: http://doc.qt.io/qt-5/qcombobox.html#currentText-prop

When the jQuery click event calls your event handler, it sets "this" to the object that was clicked on. To turn it into a jQuery object, just pass it to the "$" function: $(this). So, to get, for example, the next sibling element, you would do this inside the click handler:

var nextSibling = $(this).next();

Edit: After reading Kevin's comment, I realized I might be mistaken about what you want. If you want to do what he asked, i.e. select the corresponding link in the other div, you could use $(this).index() to get the clicked link's position. Then you would select the link in the other div by its position, for example with the "eq" method.

var $clicked = $(this);
var linkIndex = $clicked.index();
$clicked.parent().next().children().eq(linkIndex);

If you want to be able to go both ways, you will need some way of determining which div you are in so you know if you need "next()" or "prev()" after "parent()"

I found the easiest way was to create a manifest file which forces Windows to scale the application. It is blurry and non-ideal but better than an almost invisible UI! It seems this technique is applicable to any application too.

Create an eclipse.exe.manifest file in the same folder as eclipse.exe and place the following XML within it:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

I find the following setup the easiest.

Use the default config file loading mechanism of DispatcherServlet:

The framework will, on initialization of a DispatcherServlet, look for a file named [servlet-name]-servlet.xml in the WEB-INF directory of your web application and create the beans defined there (overriding the definitions of any beans defined with the same name in the global scope).

In your case, simply create a file intrafest-servlet.xml in the WEB-INF dir and don't need to specify anything specific information in web.xml.

In intrafest-servlet.xml file you can use import to compose your XML configuration.

<beans>
  <bean id="bean1" class="..."/>
  <bean id="bean2" class="..."/>

  <import resource="foo-services.xml"/>
  <import resource="foo-persistence.xml"/>
</beans>

Note that the Spring team actually prefers to load multiple config files when creating the (Web)ApplicationContext. If you still want to do it this way, I think you don't need to specify both context parameters (context-param) and servlet initialization parameters (init-param). One of the two will do. You can also use commas to specify multiple config locations.

My suggestion:

using System.Linq;

string myStringOutput = String.Join(",", myArray.Select(p => p.ToString()).ToArray());

reference: https://coderwall.com/p/oea7uq/convert-simple-int-array-to-string-c

Reflection, basically, i.e.

myObject.GetType().GetProperty(property).SetValue(myObject, "Bob", null);

or there are libraries to help both in terms of convenience and performance; for example with FastMember:

var wrapped = ObjectAccessor.Create(obj); 
wrapped[property] = "Bob";

(which also has the advantage of not needing to know in advance whether it is a field vs a property)

Since you do not mention that you want to find the intersection point of the line, the problem becomes simpler to solve. If you need the intersection point, then the answer by OMG_peanuts is a faster approach. However, if you just want to find whether the lines intersect or not, you can do so by using the line equation (ax + by + c = 0). The approach is as follows:

1. Let's start with two line segments: segment 1 and segment 2.

   segment1 = [[x1,y1], [x2,y2]]
   segment2 = [[x3,y3], [x4,y4]]
   

2. Check if the two line segments are non zero length line and distinct segments.

3. From hereon, I assume that the two segments are non-zero length and distinct. For each line segment, compute the slope of the line and then obtain the equation of a line in the form of ax + by + c = 0. Now, compute the value of f = ax + by + c for the two points of the other line segment (repeat this for the other line segment as well).

   a2 = (y3-y4)/(x3-x4);
   b1 = -1;
   b2 = -1;
   c1 = y1 - a1*x1;
   c2 = y3 - a2*x3;
   // using the sign function from numpy
   f1_1 = sign(a1*x3 + b1*y3 + c1);
   f1_2 = sign(a1*x4 + b1*y4 + c1);
   f2_1 = sign(a2*x1 + b2*y1 + c2);
   f2_2 = sign(a2*x2 + b2*y2 + c2);
   

4. Now all that is left is the different cases. If f = 0 for any point, then the two lines touch at a point. If f1_1 and f1_2 are equal or f2_1 and f2_2 are equal, then the lines do not intersect. If f1_1 and f1_2 are unequal and f2_1 and f2_2 are unequal, then the line segments intersect. Depending on whether you want to consider the lines which touch as "intersecting" or not, you can adapt your conditions.

The short answer is you can't because Math and Date (off the top of my head, I'm sure there are others) are't normal objects. To see this, create a simple test script:

<html>
  <body>
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js"></script>
    <script type="text/javascript">
      $(function() {
        alert("Math: " + Math);
        alert("Math: " + Math.sqrt);
        alert("Date: " + Date);
        alert("Array: " + Array);
        alert("jQuery: " + jQuery);
        alert("Document: " + document);
        alert("Document: " + document.ready);
      });
    </script>
  </body>
</html>

You see it presents as an object the same ways document does overall, but when you actually try and see in that object, you see that it's native code and something not exposed the same way for enumeration.

You just need to return from the main function at some point. The error message says that the function is defined to return a value but you are not returning anything.

  /* .... */
  if (Date1 == Date2)  
     fprintf (stderr , "Indicating that the first date is equal to second date.\n"); 

  return 0;
}

I found another solution for renaming a package in the entire project:

Open a file in the package. IntelliJ displays the breadcrumbs of the file, above the opened file. On the package you want renamed: Right click > Refactor > Rename. This renames the package/directory throughout the entire project.

Understand contexts

The docker build command

The basic syntax of docker's build command is

docker build -t imagename:imagetag context_dir

The context

The context is a directory and determines what the docker build process is going to see: From the Dockerfile's point of view, any file context_dir/mydir/myfile in your filesystem will become /mydir/myfile in the Dockerfile and hence during the build process.

The dockerfile

If the dockerfile is called Dockerfile and lives in the context, it will be found implicitly by naming convention. That's nice, because it means you can usually find the Dockerfile in any docker container immediately.

If you insist on using different name, say "/tmp/mydockerfile", you can use -f like this:

docker build -t imagename:imagetag -f /tmp/mydockerfile context_dir

but then the dockerfile will not be in the same folder or at least will be harder to find.

I don't know if this counts as parsing the output of git config, but this will determine the URL of the remote that master is tracking:

$ git config remote.$(git config branch.master.remote).url

Globals in Python are global to a module, not across all modules. (Many people are confused by this, because in, say, C, a global is the same across all implementation files unless you explicitly make it static.)

There are different ways to solve this, depending on your actual use case.

Before even going down this path, ask yourself whether this really needs to be global. Maybe you really want a class, with f as an instance method, rather than just a free function? Then you could do something like this:

import module1
thingy1 = module1.Thingy(a=3)
thingy1.f()

If you really do want a global, but it's just there to be used by module1, set it in that module.

import module1
module1.a=3
module1.f()

On the other hand, if a is shared by a whole lot of modules, put it somewhere else, and have everyone import it:

import shared_stuff
import module1
shared_stuff.a = 3
module1.f()

… and, in module1.py:

import shared_stuff
def f():
    print shared_stuff.a

Don't use a from import unless the variable is intended to be a constant. from shared_stuff import a would create a new a variable initialized to whatever shared_stuff.a referred to at the time of the import, and this new a variable would not be affected by assignments to shared_stuff.a.

Or, in the rare case that you really do need it to be truly global everywhere, like a builtin, add it to the builtin module. The exact details differ between Python 2.x and 3.x. In 3.x, it works like this:

import builtins
import module1
builtins.a = 3
module1.f()

Check if below are enabled

bz, mbstring, intl, ioncube_loader and Json extension.

Listview so have inbuild scrolling capabilities. So you can not use listview inside scrollview. Encapsulate it in any other layout like LinearLayout or RelativeLayout.

After version 2.23, Git has introduced the git restore command which you can use to do that. Quoting the official documentation:

Restore specified paths in the working tree with some contents from a restore source. If a path is tracked but does not exist in the restore source, it will be removed to match the source.

The command can also be used to restore the content in the index with --staged, or restore both the working tree and the index with --staged --worktree.

So you can invoke git restore --staged <path> and unstage the file but also keep the changes you made. Remember that if the file was not staged you lose all the changes you made to it.

You have added the CSRF field incorrectly. Instead of @csrf you should use csrf_field() like this:

<form method="POST" action="/foo" >
    {{ csrf_field() }}
    <input type="text" name="name"/><br/>
    <input type="submit" value="Add"/>
</form>

you can try just add

network_mode: "host"

example :

version: '2'
services:
  feedx:
    build: web
    ports:
    - "127.0.0.1:8000:8000"
    network_mode: "host"

list option available

Just to add to roya's answer. In c# 6.0 you can now use string interpolation:

Console.WriteLine($"{customer[DisplayPos],10}" +
                  $"{salesFigures[DisplayPos],10}" +
                  $"{feePayable[DisplayPos],10}" +
                  $"{seventyPercentValue,10}" +
                  $"{thirtyPercentValue,10}");

This can actually be one line without all the extra dollars, I just think it makes it a bit easier to read like this.

And you could also use a static import on System.Console, allowing you to do this:

using static System.Console;

WriteLine(/* write stuff */);

You can use two way:

1: You just keep the necessary columns:

drop_column_list = ["drop_column"]
df = df.select([column for column in df.columns if column not in drop_column_list])  

2: This is the more elegant way.

df = df.drop("col_name")

You should avoid the collect() version, because it will send to the master the complete dataset, it will take a big computing effort!

The correct answer is don't do that, use the HTML Agility Pack.

Edited to add:

To shamelessly steal from the comment below by jesse, and to avoid being accused of inadequately answering the question after all this time, here's a simple, reliable snippet using the HTML Agility Pack that works with even most imperfectly formed, capricious bits of HTML:

HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(Properties.Resources.HtmlContents);
var text = doc.DocumentNode.SelectNodes("//body//text()").Select(node => node.InnerText);
StringBuilder output = new StringBuilder();
foreach (string line in text)
{
   output.AppendLine(line);
}
string textOnly = HttpUtility.HtmlDecode(output.ToString());

There are very few defensible cases for using a regular expression for parsing HTML, as HTML can't be parsed correctly without a context-awareness that's very painful to provide even in a nontraditional regex engine. You can get part way there with a RegEx, but you'll need to do manual verifications.

Html Agility Pack can provide you a robust solution that will reduce the need to manually fix up the aberrations that can result from naively treating HTML as a context-free grammar.

A regular expression may get you mostly what you want most of the time, but it will fail on very common cases. If you can find a better/faster parser than HTML Agility Pack, go for it, but please don't subject the world to more broken HTML hackery.

switch() is a powerful and standard way of implementing state machines in C, but it can decrease maintainability down if you have a large number of states. Another common method is to use function pointers to store the next state. This simple example implements a set/reset flip-flop:

/* Implement each state as a function with the same prototype */
void state_one(int set, int reset);
void state_two(int set, int reset);

/* Store a pointer to the next state */
void (*next_state)(int set, int reset) = state_one;

/* Users should call next_state(set, reset). This could
   also be wrapped by a real function that validated input
   and dealt with output rather than calling the function
   pointer directly. */

/* State one transitions to state one if set is true */
void state_one(int set, int reset) {
    if(set)
        next_state = state_two;
}

/* State two transitions to state one if reset is true */
void state_two(int set, int reset) {
    if(reset)
        next_state = state_one;
}

Use dynamic linq

just add using System.Linq.Dynamic;

And use it like this to order all your columns:

string sortTypeStr = "ASC"; // or DESC
string SortColumnName = "Age"; // Your column name
query = query.OrderBy($"{SortColumnName} {sortTypeStr}");

Found this to be an issue when using Lollipop's Heads Up Display notification. See design guidelines. Here's the complete(ish) code to implement.

Until now, having a 'Dismiss' button was less important, but now it's more in your face.

Building the Notification

int notificationId = new Random().nextInt(); // just use a counter in some util class...
PendingIntent dismissIntent = NotificationActivity.getDismissIntent(notificationId, context);

NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
builder.setPriority(NotificationCompat.PRIORITY_MAX) //HIGH, MAX, FULL_SCREEN and setDefaults(Notification.DEFAULT_ALL) will make it a Heads Up Display Style
        .setDefaults(Notification.DEFAULT_ALL) // also requires VIBRATE permission
        .setSmallIcon(R.drawable.ic_action_refresh) // Required!
        .setContentTitle("Message from test")
        .setContentText("message")
        .setAutoCancel(true)
        .addAction(R.drawable.ic_action_cancel, "Dismiss", dismissIntent)
        .addAction(R.drawable.ic_action_boom, "Action!", someOtherPendingIntent);

// Gets an instance of the NotificationManager service
NotificationManager notifyMgr = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

// Builds the notification and issues it.
notifyMgr.notify(notificationId, builder.build());

NotificationActivity

public class NotificationActivity extends Activity {

    public static final String NOTIFICATION_ID = "NOTIFICATION_ID";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        manager.cancel(getIntent().getIntExtra(NOTIFICATION_ID, -1));
        finish(); // since finish() is called in onCreate(), onDestroy() will be called immediately
    }

    public static PendingIntent getDismissIntent(int notificationId, Context context) {
        Intent intent = new Intent(context, NotificationActivity.class);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
        intent.putExtra(NOTIFICATION_ID, notificationId);
        PendingIntent dismissIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);
        return dismissIntent;
    }

}

AndroidManifest.xml (attributes required to prevent SystemUI from focusing to a back stack)

<activity
    android:name=".NotificationActivity"
    android:taskAffinity=""
    android:excludeFromRecents="true">
</activity>

You need to apply DATE_FORMAT in the SELECT clause, not the WHERE clause:

SELECT  DATE_FORMAT(create_date, '%m/%d/%Y')
FROM    mytable
WHERE   create_date BETWEEN CURDATE() - INTERVAL 30 DAY AND CURDATE()

Also note that CURDATE() returns only the DATE portion of the date, so if you store create_date as a DATETIME with the time portion filled, this query will not select the today's records.

In this case, you'll need to use NOW instead:

SELECT  DATE_FORMAT(create_date, '%m/%d/%Y')
FROM    mytable
WHERE   create_date BETWEEN NOW() - INTERVAL 30 DAY AND NOW()

I tried commands from listed answers here but pods were stuck in terminating state.
I found below command to delete all pods from particular namespace if stuck in terminating state or you are not able to delete it then you can delete pods forcefully.

kubectl delete pods --all --grace-period=0 --force --namespace namespace

Hope it might be useful to someone.

To use the environment virtualenv has created, you first need to source env/bin/activate. After that, just install packages using pip install package-name.

You can use git checkout.

I tried the accepted solution but got an error, warning: refname '<tagname>' is ambiguous'

But as the answer states, tags do behave like a pointer to a commit, so as you would with a commit hash, you can just checkout the tag. The only difference is you preface it with tags/:

git checkout tags/<tagname>

Note: The category parameter needs to be the ID of the category, and not the category name.

To turn off foreign key constraint globally, do the following:

SET GLOBAL FOREIGN_KEY_CHECKS=0;

and remember to set it back when you are done

SET GLOBAL FOREIGN_KEY_CHECKS=1;

WARNING: You should only do this when you are doing single user mode maintenance. As it might resulted in data inconsistency. For example, it will be very helpful when you are uploading large amount of data using a mysqldump output.

Your session status are set once you start a session, and by default, take the current GLOBAL value.

If you disconnected after you did SET @@GLOBAL.wait_timeout=300, then subsequently reconnected, you'd see

SHOW SESSION VARIABLES LIKE "%wait%";

Result: 300

Similarly, at any time, if you did

mysql> SET session wait_timeout=300;

You'd get

mysql> SHOW SESSION VARIABLES LIKE 'wait_timeout';

+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| wait_timeout  | 300   |
+---------------+-------+

The CLR uses it when it is compiling at runtime. Here is a link to MSDN that explains further.

Here is an example for how to extract the href attrbiutes of all a tags:

import requests as rq 
from bs4 import BeautifulSoup as bs

url = "http://www.cde.ca.gov/ds/sp/ai/"
page = rq.get(url)
html = bs(page.text, 'lxml')

hrefs = html.find_all("a")
all_hrefs = []
for href in hrefs:
    # print(href.get("href"))
    links = href.get("href")
    all_hrefs.append(links)

print(all_hrefs)

If you are 100% sure that directories and files are ok, have a look at the project location.

There is a limit on the path length of files in the Operating System. Perhaps this limit is being exceded in your project files.

Move the project to a shorter folder (say C:/MyProject) and try again!

This was the problem for me!

Unless I'm mistaken, I'd say it's to write your own function.

function findIndexOfGreatest(array) {
  var greatest;
  var indexOfGreatest;
  for (var i = 0; i < array.length; i++) {
    if (!greatest || array[i] > greatest) {
      greatest = array[i];
      indexOfGreatest = i;
    }
  }
  return indexOfGreatest;
}

Overview

Why do we need the copy-and-swap idiom?

Any class that manages a resource (a wrapper, like a smart pointer) needs to implement The Big Three. While the goals and implementation of the copy-constructor and destructor are straightforward, the copy-assignment operator is arguably the most nuanced and difficult. How should it be done? What pitfalls need to be avoided?

The copy-and-swap idiom is the solution, and elegantly assists the assignment operator in achieving two things: avoiding code duplication, and providing a strong exception guarantee.

How does it work?

Conceptually, it works by using the copy-constructor's functionality to create a local copy of the data, then takes the copied data with a swap function, swapping the old data with the new data. The temporary copy then destructs, taking the old data with it. We are left with a copy of the new data.

In order to use the copy-and-swap idiom, we need three things: a working copy-constructor, a working destructor (both are the basis of any wrapper, so should be complete anyway), and a swap function.

A swap function is a non-throwing function that swaps two objects of a class, member for member. We might be tempted to use std::swap instead of providing our own, but this would be impossible; std::swap uses the copy-constructor and copy-assignment operator within its implementation, and we'd ultimately be trying to define the assignment operator in terms of itself!

(Not only that, but unqualified calls to swap will use our custom swap operator, skipping over the unnecessary construction and destruction of our class that std::swap would entail.)

An in-depth explanation

The goal

Let's consider a concrete case. We want to manage, in an otherwise useless class, a dynamic array. We start with a working constructor, copy-constructor, and destructor:

#include <algorithm> // std::copy
#include <cstddef> // std::size_t

class dumb_array
{
public:
    // (default) constructor
    dumb_array(std::size_t size = 0)
        : mSize(size),
          mArray(mSize ? new int[mSize]() : nullptr)
    {
    }

    // copy-constructor
    dumb_array(const dumb_array& other)
        : mSize(other.mSize),
          mArray(mSize ? new int[mSize] : nullptr),
    {
        // note that this is non-throwing, because of the data
        // types being used; more attention to detail with regards
        // to exceptions must be given in a more general case, however
        std::copy(other.mArray, other.mArray + mSize, mArray);
    }

    // destructor
    ~dumb_array()
    {
        delete [] mArray;
    }

private:
    std::size_t mSize;
    int* mArray;
};

This class almost manages the array successfully, but it needs operator= to work correctly.

A failed solution

Here's how a naive implementation might look:

// the hard part
dumb_array& operator=(const dumb_array& other)
{
    if (this != &other) // (1)
    {
        // get rid of the old data...
        delete [] mArray; // (2)
        mArray = nullptr; // (2) *(see footnote for rationale)

        // ...and put in the new
        mSize = other.mSize; // (3)
        mArray = mSize ? new int[mSize] : nullptr; // (3)
        std::copy(other.mArray, other.mArray + mSize, mArray); // (3)
    }

    return *this;
}

And we say we're finished; this now manages an array, without leaks. However, it suffers from three problems, marked sequentially in the code as (n).

1. The first is the self-assignment test. This check serves two purposes: it's an easy way to prevent us from running needless code on self-assignment, and it protects us from subtle bugs (such as deleting the array only to try and copy it). But in all other cases it merely serves to slow the program down, and act as noise in the code; self-assignment rarely occurs, so most of the time this check is a waste. It would be better if the operator could work properly without it.

2. The second is that it only provides a basic exception guarantee. If new int[mSize] fails, *this will have been modified. (Namely, the size is wrong and the data is gone!) For a strong exception guarantee, it would need to be something akin to:

   dumb_array& operator=(const dumb_array& other)
   {
       if (this != &other) // (1)
       {
           // get the new data ready before we replace the old
           std::size_t newSize = other.mSize;
           int* newArray = newSize ? new int[newSize]() : nullptr; // (3)
           std::copy(other.mArray, other.mArray + newSize, newArray); // (3)
   
           // replace the old data (all are non-throwing)
           delete [] mArray;
           mSize = newSize;
           mArray = newArray;
       }
   
       return *this;
   }
   

3. The code has expanded! Which leads us to the third problem: code duplication. Our assignment operator effectively duplicates all the code we've already written elsewhere, and that's a terrible thing.

In our case, the core of it is only two lines (the allocation and the copy), but with more complex resources this code bloat can be quite a hassle. We should strive to never repeat ourselves.

(One might wonder: if this much code is needed to manage one resource correctly, what if my class manages more than one? While this may seem to be a valid concern, and indeed it requires non-trivial try/catch clauses, this is a non-issue. That's because a class should manage one resource only!)

A successful solution

As mentioned, the copy-and-swap idiom will fix all these issues. But right now, we have all the requirements except one: a swap function. While The Rule of Three successfully entails the existence of our copy-constructor, assignment operator, and destructor, it should really be called "The Big Three and A Half": any time your class manages a resource it also makes sense to provide a swap function.

We need to add swap functionality to our class, and we do that as follows†:

class dumb_array
{
public:
    // ...

    friend void swap(dumb_array& first, dumb_array& second) // nothrow
    {
        // enable ADL (not necessary in our case, but good practice)
        using std::swap;

        // by swapping the members of two objects,
        // the two objects are effectively swapped
        swap(first.mSize, second.mSize);
        swap(first.mArray, second.mArray);
    }

    // ...
};

(Here is the explanation why public friend swap.) Now not only can we swap our dumb_array's, but swaps in general can be more efficient; it merely swaps pointers and sizes, rather than allocating and copying entire arrays. Aside from this bonus in functionality and efficiency, we are now ready to implement the copy-and-swap idiom.

Without further ado, our assignment operator is:

dumb_array& operator=(dumb_array other) // (1)
{
    swap(*this, other); // (2)

    return *this;
}

And that's it! With one fell swoop, all three problems are elegantly tackled at once.

Why does it work?

We first notice an important choice: the parameter argument is taken by-value. While one could just as easily do the following (and indeed, many naive implementations of the idiom do):

dumb_array& operator=(const dumb_array& other)
{
    dumb_array temp(other);
    swap(*this, temp);

    return *this;
}

We lose an important optimization opportunity. Not only that, but this choice is critical in C++11, which is discussed later. (On a general note, a remarkably useful guideline is as follows: if you're going to make a copy of something in a function, let the compiler do it in the parameter list.‡)

Either way, this method of obtaining our resource is the key to eliminating code duplication: we get to use the code from the copy-constructor to make the copy, and never need to repeat any bit of it. Now that the copy is made, we are ready to swap.

Observe that upon entering the function that all the new data is already allocated, copied, and ready to be used. This is what gives us a strong exception guarantee for free: we won't even enter the function if construction of the copy fails, and it's therefore not possible to alter the state of *this. (What we did manually before for a strong exception guarantee, the compiler is doing for us now; how kind.)

At this point we are home-free, because swap is non-throwing. We swap our current data with the copied data, safely altering our state, and the old data gets put into the temporary. The old data is then released when the function returns. (Where upon the parameter's scope ends and its destructor is called.)

Because the idiom repeats no code, we cannot introduce bugs within the operator. Note that this means we are rid of the need for a self-assignment check, allowing a single uniform implementation of operator=. (Additionally, we no longer have a performance penalty on non-self-assignments.)

And that is the copy-and-swap idiom.

What about C++11?

The next version of C++, C++11, makes one very important change to how we manage resources: the Rule of Three is now The Rule of Four (and a half). Why? Because not only do we need to be able to copy-construct our resource, we need to move-construct it as well.

Luckily for us, this is easy:

class dumb_array
{
public:
    // ...

    // move constructor
    dumb_array(dumb_array&& other) noexcept ††
        : dumb_array() // initialize via default constructor, C++11 only
    {
        swap(*this, other);
    }

    // ...
};

What's going on here? Recall the goal of move-construction: to take the resources from another instance of the class, leaving it in a state guaranteed to be assignable and destructible.

So what we've done is simple: initialize via the default constructor (a C++11 feature), then swap with other; we know a default constructed instance of our class can safely be assigned and destructed, so we know other will be able to do the same, after swapping.

(Note that some compilers do not support constructor delegation; in this case, we have to manually default construct the class. This is an unfortunate but luckily trivial task.)

Why does that work?

That is the only change we need to make to our class, so why does it work? Remember the ever-important decision we made to make the parameter a value and not a reference:

dumb_array& operator=(dumb_array other); // (1)

Now, if other is being initialized with an rvalue, it will be move-constructed. Perfect. In the same way C++03 let us re-use our copy-constructor functionality by taking the argument by-value, C++11 will automatically pick the move-constructor when appropriate as well. (And, of course, as mentioned in previously linked article, the copying/moving of the value may simply be elided altogether.)

And so concludes the copy-and-swap idiom.

Footnotes

*Why do we set mArray to null? Because if any further code in the operator throws, the destructor of dumb_array might be called; and if that happens without setting it to null, we attempt to delete memory that's already been deleted! We avoid this by setting it to null, as deleting null is a no-operation.

†There are other claims that we should specialize std::swap for our type, provide an in-class swap along-side a free-function swap, etc. But this is all unnecessary: any proper use of swap will be through an unqualified call, and our function will be found through ADL. One function will do.

‡The reason is simple: once you have the resource to yourself, you may swap and/or move it (C++11) anywhere it needs to be. And by making the copy in the parameter list, you maximize optimization.

††The move constructor should generally be noexcept, otherwise some code (e.g. std::vector resizing logic) will use the copy constructor even when a move would make sense. Of course, only mark it noexcept if the code inside doesn't throw exceptions.

The problem you're having is that you're passing incompatible formats from a formatted java.util.Date to construct an instance of java.sql.Date, which don't behave in the same way when using valueOf() since they use different formats.

I also can see that you're aiming to persist hours and minutes, and I think that you'd better change the data type to java.sql.Timestamp, which supports hours and minutes, along with changing your database field to DATETIME or similar (depending on your database vendor).

Anyways, if you want to change from java.util.Date to java.sql.Date, I suggest to use

java.util.Date date = Calendar.getInstance().getTime();
java.sql.Date sqlDate = new java.sql.Date(date.getTime()); 
// ... more code here
prs.setDate(sqlDate);

jQuery(".megamenu li.level0 .dropdown-container .sub-column ul .level1").on("mouseover", function () {
    var sum = 0;
    jQuery(this).find('ul li.level2').each(function(){
    sum -= jQuery(this).height();
    jQuery(this).parent('ul').css('margin-top', sum / 1.8);
    console.log(sum);
    });
});

On hover we can calculate the list item height.

It probably is the # sign like tho others have mentioned because this appears to work just fine.

Yes, underscores may be used anywhere in an identifier. I believe the rules are: any of a-z, A-Z, _ in the first character and those +0-9 for the following characters.

Underscore prefixes are common in C code -- a single underscore means "private", and double underscores are usually reserved for use by the compiler.

Minimalistic approach that just meets the original requirements:

function formatMoney(n) {
    return "$ " + (Math.round(n * 100) / 100).toLocaleString();
}

@Daniel Magliola: You're right, the above was a hasty, incomplete implementation. Here's the corrected implementation:

function formatMoney(n) {
    return "$ " + n.toLocaleString().split(".")[0] + "."
        + n.toFixed(2).split(".")[1];
}

Building on what has been said before, this is a pure CSS solution that works.

In most languages i am aware of, the actual regex for validating should be ^[0-9]{1,10}$; otherwise the matcher will also return positive matches if the to be validated number is part of a longer string.

EDIT: As of Go 1.8 (Released February 2017) the recommended way of doing this is with os.Executable:

func Executable() (string, error)

Executable returns the path name for the executable that started the current process. There is no guarantee that the path is still pointing to the correct executable. If a symlink was used to start the process, depending on the operating system, the result might be the symlink or the path it pointed to. If a stable result is needed, path/filepath.EvalSymlinks might help.

To get just the directory of the executable you can use path/filepath.Dir.

Example:

package main

import (
    "fmt"
    "os"
    "path/filepath"
)

func main() {
    ex, err := os.Executable()
    if err != nil {
        panic(err)
    }
    exPath := filepath.Dir(ex)
    fmt.Println(exPath)
}

OLD ANSWER:

You should be able to use os.Getwd

func Getwd() (pwd string, err error)

Getwd returns a rooted path name corresponding to the current directory. If the current directory can be reached via multiple paths (due to symbolic links), Getwd may return any one of them.

For example:

package main

import (
    "fmt"
    "os"
)

func main() {
    pwd, err := os.Getwd()
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }
    fmt.Println(pwd)
}

Use position:fixed, as previously stated, IE6 doesn't recognize position:fixed, but with some css magic you can get IE6 to behave:

html, body {
    height: 100%;
    overflow:auto;
}
body #fixedElement {
    position:fixed !important;
    position: absolute; /*ie6 */
    bottom: 0;
}

The !important flag makes it so you don't have to use a conditional comment for IE. This will have #fixedElement use position:fixed in all browsers but IE, and in IE, position:absolute will take effect with bottom:0. This will simulate position:fixed for IE6

If your drive letter is C, you should be able to use

scp -r \desktop\myfolder\deployments\ user@host:/path/to/whereyouwant/thefile

without drive letter and backslashes instead of forward slashes.

You are using putty, so you can use pscp. It is better adapted to Windows.

If you want to remove the default value constraint, you can do:

ALTER TABLE <table> ALTER COLUMN <column> DROP DEFAULT;

Simply use substr for string

ex.

var str = "Hello world!";
var res = str.substr(1, str.length);

Result = ello world!

You can try use simple command line. bcdedit is what you need, just run cmd as administrator and type bcdedit or bcdedit \v, this doesn't work on XP, but hope it is not an issue.

Anyway for XP you can take a look into boot.ini file.

I access main properties using $root.

Vue.component("example", { 
    template: `<div>$root.message</div>`
});

The min sdk version is the earliest release of the Android SDK that your application can run on. Usually this is because of a problem with the earlier APIs, lacking functionality, or some other behavioural issue.

The target sdk version is the version your application was targeted to run on. Ideally, this is because of some sort of optimal run conditions. If you were to "make your app for version 19", this is where that would be specified. It may run on earlier or later releases, but this is what you were aiming for. This is mostly to indicate how current your application is for use in the marketplace, etc.

The compile sdk version is the version of android your IDE (or other means of compiling I suppose) uses to make your app when you publish a .apk file. This is useful for testing your application as it is a common need to compile your app as you develop it. As this will be the version to compile to an APK, it will naturally be the version of your release. Likewise, it is advisable to have this match your target sdk version.

This will give you an array with 50 random numbers and display the smallest number in the array. I did it for an assignment in my programming class.

public static void main(String args[]) {
    // TODO Auto-generated method stub

    int i;
    int[] array = new int[50];
    for(i = 0; i <  array.length; i++) {
        array[i] = (int)(Math.random() * 100);
        System.out.print(array[i] + "  ");

        int smallest = array[0];

        for (i=1; i<array.length; i++)
        {
        if (array[i]<smallest)
        smallest = array[i];
        }



    }

}

}`

This answer is going to be for the question

How to create a new eclipse project and add a folder or a new package into the project, or how to build a new project for existing java files.

1. Create a new project from the menu File->New-> Java Project
2. If you are going to add a new pakcage, then create the same package name here by File->New-> Package
3. Click the name of the package in project navigator, and right click, and import... Import->General->File system (choose your file or package)

this worked for me I hope it helps others. Thank you.

A save method to determine the width and height unit of any element (no padding, no margin) is the following:

let div   = document.querySelector("div");
let style = getComputedStyle(div);

let width  = parseFloat(style.width.replace("px", ""));
let height = parseFloat(style.height.replace("px", ""));

If the files which you are loading are cached and if the changes you have made does not reflect in the code then there are 2 ways you can deal with this

1. Clear the Cache as everyone told

2. If u want Cache and only the files have to be reloaded , you can go to network tab of the dev tool and clear whatever was loaded. next time it will not load it from cache. you will have your latest changes.

import os

path, dirs, files = next(os.walk("/usr/lib"))
file_count = len(files)

If you have two DateTime that looks the same, but Compare or Equals doesn't return what you expect, this is how to compare them.

Here an example with 1-millisecond precision:

bool areSame = (date1 - date2) > TimeSpan.FromMilliseconds(1d);

You can simply run this command:

npm install grunt --save-dev

You might find the Semantic Versioning Specification useful.

<select [(ngModel)]="selectedcarrera" (change)="mostrardatos()" class="form-control" name="carreras">
    <option *ngFor="let x of carreras" [ngValue]="x"> {{x.nombre}} </option>
</select>

In ts

mostrardatos(){

}

A section is basically a wrapper for h1 (or other h tags) and the content that corresponds to this. An article is essentially a document within your document that is repeated or paginated...like each blog post on your document can be an article, or each comment on your document can be an article.

putting NOW() in quotes won't work as Active Records will put escape the NOW() into a string and tries to push it into the db as a string of "NOW()"... you will need to use

$this->db->set('time', 'NOW()', FALSE); 

to set it correctly.

you can always check your sql afterward with

$this->db->last_query();

Your browser hasn't interpretted the encoding of the page correctly (either because you've forced it to a particular setting, or the page is set incorrectly), and thus cannot display some of the characters.

I'm doing something very similar in a private project I'm working on. Thus far I've generated images up to 1024x1024 without any problems (except memory) and can display them very quickly and without any performance problems.

Overriding the paint method of JPanel subclass is overkill and requires more work than you need to do.

The way I do it is:

Class MapIcon implements Icon {...}

OR

Class MapIcon extends ImageIcon {...}

The code you use to generate the image will be in this class. I use a BufferedImage to draw onto then when the paintIcon() is called, use g.drawImvge(bufferedImage); This reduces the amount of flashing done while you generate your images, and you can thread it.

Next I extend JLabel:

Class MapLabel extends Scrollable, MouseMotionListener {...}

This is because I want to put my image on a scroll pane, I.e. display part of the image and have the user scroll around as needed.

So then I use a JScrollPane to hold the MapLabel, which contains only the MapIcon.

MapIcon map = new MapIcon (); 
MapLabel mapLabel = new MapLabel (map);
JScrollPane scrollPane = new JScrollPane();

scrollPane.getViewport ().add (mapLabel);

But for your scenario (just show the whole image every time). You need to add the MapLabel to the top JPanel, and make sure to size them all to the full size of the image (by overriding the GetPreferredSize()).

I extended Ronnie's answer with a fluent implementation so you can use it like so:

dm.Context.SetCommandTimeout(120).Database.SqlQuery...

public static class EF
{
    public static DbContext SetCommandTimeout(this DbContext db, TimeSpan? timeout)
    {
        ((IObjectContextAdapter)db).ObjectContext.CommandTimeout = timeout.HasValue ? (int?) timeout.Value.TotalSeconds : null;

        return db;
    }

    public static DbContext SetCommandTimeout(this DbContext db, int seconds)
    {
        return db.SetCommandTimeout(TimeSpan.FromSeconds(seconds));
    } 
}

String Declaration:

String str;

String Initialization

String[] str=new String[3];//if we give string[2] will get Exception insted
str[0]="Tej";
str[1]="Good";
str[2]="Girl";

String str="SSN"; 

We can get individual character in String:

char chr=str.charAt(0);`//output will be S`

If I want to to get individual character Ascii value like this:

System.out.println((int)chr); //output:83

Now i want to convert Ascii value into Charecter/Symbol.

int n=(int)chr;
System.out.println((char)n);//output:S

Java doesn't overload operators, so you'll usually need a method for non-basic types. Try the Arrays.equals() method.

You should always try to use a composite object with concrete types (using composite design pattern) rather than a list of object types. Who would remember what the heck each of those objects is? Think about maintenance of your code later on... Instead, try something like this:

Public (Class or Structure) MyPerson
                public string FirstName { get; set; }
                public string LastName { get; set; }
                public string Address { get; set; }
                public int ZipCode { get; set; }
End Class

And then:

Dim person as new MyPerson With { .FirstName = “Joe”,
                                  .LastName = "Smith”,
                                  ...
                                 }
backgroundWorker1.RunWorkerAsync(person)

and then:

private void backgroundWorker1_DoWork (object sender, DoWorkEventArgs e)
{
        MyPerson person = e.Argument as MyPerson
        string firstname = person.FirstName;
        string lastname = person.LastName;
        int zipcode = person.ZipCode;                                 
}

This is the syntax: "python.exe path""python script path"pause

"C:\Users\hp\AppData\Local\Programs\Python\Python37\python.exe" "D:\TS_V1\TS_V2.py"
pause

Basically what will be happening the screen will appear for seconds and then go off take care of these 2 things:

1. While saving the file you give extension as bat file but save it as a txt file and not all files and Encoding ANSI
2. If the program still doesn't run save the batch file and the python script in same folder and specify the path of this folder in Environment Variables.

When neither sudo nor apt-get is available in container, you can also jump into running container as root user using command

docker exec -u root -t -i container_id /bin/bash

For the executable name, the new-alias cmdlet can be employed to avoid dealing with spaces or needing to add the executable to the $PATH environment.

PS> new-alias msdeploy "C:\Program Files\IIS\Microsoft Web Deploy\msdeploy.exe"
PS> msdeploy ...

To list or modify PS aliases also see

PS> get-alias
PS> set-alias

Other answers address the arguments.

This fixes the math to scale to the max size in both width and height rather than just one depending on the width and height of the original.

- (UIImage *) scaleProportionalToSize: (CGSize)size
{
    float widthRatio = size.width/self.size.width;
    float heightRatio = size.height/self.size.height;

    if(widthRatio > heightRatio)
    {
        size=CGSizeMake(self.size.width*heightRatio,self.size.height*heightRatio);
    } else {
        size=CGSizeMake(self.size.width*widthRatio,self.size.height*widthRatio);
    }

    return [self scaleToSize:size];
}

If you are just getting started with a new project then I would suggest that you use PDO instead of the old odbc_exec() approach. Here is a simple example:

<?php
$bits = 8 * PHP_INT_SIZE;
echo "(Info: This script is running as $bits-bit.)\r\n\r\n";

$connStr = 
        'odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};' .
        'Dbq=C:\\Users\\Gord\\Desktop\\foo.accdb;';

$dbh = new PDO($connStr);
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

$sql = 
        "SELECT AgentName FROM Agents " .
        "WHERE ID < ? AND AgentName <> ?";
$sth = $dbh->prepare($sql);

// query parameter value(s)
$params = array(
        5,
        'Homer'
        );

$sth->execute($params);

while ($row = $sth->fetch()) {
    echo $row['AgentName'] . "\r\n";
}

NOTE: The above approach is sufficient if you do not need to support Unicode characters above U+00FF. If you do need to support such characters then neither PDO_ODBC nor the old odbc_ functions will work; you'll need to use the solution described in this answer.

All of these answers are using Linux consoles to access MySQL.

If you are on Windows and are using WAMP, you can start by opening the MySQL console (click WAMP icon->MySQL->MySQL console).

Then it will request you to enter your current password, enter it.

And then type SET PASSWORD = PASSWORD('some_pass');

This happens because your click handler fires before the value of the radio button changes. You need to listen to the change event instead:

<input 
  type="radio" 
  name="optionsRadios" 
  id="optionsRadios2" 
  value=""
  v-model="srStatus" 
  v-on:change="foo"> //here

Also, make sure you really want to call foo() on ready... seems like maybe you don't actually want to do that.

ready:function(){
    foo();
},

Your guess is right: the code is trying to evaluate x**3+2*x-4 immediately. Unfortunately you can't really prevent it from doing so. The good news is that in Python, functions are first-class objects, by which I mean that you can treat them like any other variable. So to fix your function, we could do:

import numpy as np  
import matplotlib.pyplot as plt  

def graph(formula, x_range):  
    x = np.array(x_range)  
    y = formula(x)  # <- note now we're calling the function 'formula' with x
    plt.plot(x, y)  
    plt.show()  

def my_formula(x):
    return x**3+2*x-4

graph(my_formula, range(-10, 11))

If you wanted to do it all in one line, you could use what's called a lambda function, which is just a short function without a name where you don't use def or return:

graph(lambda x: x**3+2*x-4, range(-10, 11))

And instead of range, you can look at np.arange (which allows for non-integer increments), and np.linspace, which allows you to specify the start, stop, and the number of points to use.

Check that ruby interpreter is already installed and try "ruby setup.rb" in command prompt.

$(document).ready(function(){
  $('#shares').val('');
});

The error indicates that the preflight is getting a redirect response. This can happen for a number of reasons. Find out where you are getting redirected to for clues to why it is happening. Check the network tab in Developer Tools.

One reason, as @Peter T mentioned, is that the API likely requires HTTPS connections rather than HTTP and all requests over HTTP get redirected. The Location header returned by the 302 response would say the same url with http changed to https in this case.

Another reason might be that your authentication token is not getting sent, or is not correct. Most servers are set up to redirect all requests that don't include an authentication token to the login page. Again, check your Location header to see if this is where you're getting sent and also take a look to make sure the browser sent your auth token with the request.

Oftentimes, a server will be configured to always redirect requests that don't have auth tokens to the login page - including your preflight/OPTIONS requests. This is a problem. Change the server configuration to permit OPTIONS requests from non-authenticated users.

Or use a cast with split to uniform type of str

unique, counts = numpy.unique(str(a).split(), return_counts=True)

If using PHP7, I would suggest you changing the default value in the public/.htaccess

<IfModule php7_module>
   ...
   php_value max_execution_time 300
   ...
</IfModule>

A lot of people have some very interesting techniques but I like to keep it simple so I go with this :

public static String padRight(String s, int n, char padding){
    StringBuilder builder = new StringBuilder(s.length() + n);
    builder.append(s);
    for(int i = 0; i < n; i++){
        builder.append(padding);
    }
    return builder.toString();
}

public static String padLeft(String s, int n,  char padding) {
    StringBuilder builder = new StringBuilder(s.length() + n);
    for(int i = 0; i < n; i++){
        builder.append(Character.toString(padding));
    }
    return builder.append(s).toString();
}

public static String pad(String s, int n, char padding){
    StringBuilder pad = new StringBuilder(s.length() + n * 2);
    StringBuilder value = new StringBuilder(n);
    for(int i = 0; i < n; i++){
        pad.append(padding);
    }
    return value.append(pad).append(s).append(pad).toString();
}

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

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

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

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

You are just comparing strings.

Put the values in ArrayList A as keys in HashTable A.
Put the values in ArrayList B as keys in HashTable B.

Then, for each key in HashTable A, remove it from HashTable B if it exists.

What you are left with in HashTable B are the strings (keys) that were not values in ArrayList A.

C# (3.0) example added in response to request for code:

List<string> listA = new List<string>{"2009-05-18","2009-05-19","2009-05-21'"};
List<string> listB = new List<string>{"2009-05-18","2009-05-18","2009-05-19","2009-05-19","2009-05-20","2009-05-21","2009-05-21","2009-05-22"};

HashSet<string> hashA = new HashSet<string>();
HashSet<string> hashB = new HashSet<string>();

foreach (string dateStrA in listA) hashA.Add(dateStrA);
foreach (string dateStrB in listB) hashB.Add(dateStrB);

foreach (string dateStrA in hashA)
{
    if (hashB.Contains(dateStrA)) hashB.Remove(dateStrA);
}

List<string> result = hashB.ToList<string>();

Thanks for that info on the ControlToValidate LukeH!

What I was trying to do in my code was to only ensure that some text field A has some text in the field when text field B has a particular value. Otherwise, A can be blank or whatever else. Getting rid of the ControlToValidate="A" in my mark up fixed the issue for me.

Cheers!

The pointer-events could be useful for this problem as you would be able to put a div over the arrow button, but still be able to click the arrow button.

The pointer-events css makes it possible to click through a div.

This approach will not work for IE versions older than IE11, however. You could something working in IE8 and IE9 if the element you put on top of the arrow button is an SVG element, but it will be more complicated to style the button the way you want proceeding like this.

Here a Js fiddle example: http://jsfiddle.net/e7qnqzx6/2/

You can check the socket.connected property:

var socket = io.connect();
console.log('check 1', socket.connected);
socket.on('connect', function() {
  console.log('check 2', socket.connected);
});

It's updated dynamically, if the connection is lost it'll be set to false until the client picks up the connection again. So easy to check for with setInterval or something like that.

Another solution would be to catch disconnect events and track the status yourself.

All of these answers are turned off the logging at creation time.

But what if we need to turn off the logging on runtime ?

By runtime i mean after initializing the sequelize object using new Sequelize(.. function.

I peeked into the github source, found a way to turn off logging in runtime.

// Somewhere your code, turn off the logging
sequelize.options.logging = false

// Somewhere your code, turn on the logging
sequelize.options.logging = true
