That's odd. Does your program compile and run successfully and only fail on 'Publish' or does it fail on every compile now?

Also, have you perhaps changed the file's properties' Build Action to something other than Compile?

Suppose you want to execute a notification when each node in a graph is visited. The simple recursive implementation is:

void DFSRecursive(Node n, Set<Node> visited) {
  visited.add(n);
  for (Node x : neighbors_of(n)) {  // iterate over all neighbors
    if (!visited.contains(x)) {
      DFSRecursive(x, visited);
    }
  }
  OnVisit(n);  // callback to say node is finally visited, after all its non-visited neighbors
}

Ok, now you want a stack-based implementation because your example doesn't work. Complex graphs might for instance cause this to blow the stack of your program and you need to implement a non-recursive version. The biggest issue is to know when to issue a notification.

The following pseudo-code works (mix of Java and C++ for readability):

void DFS(Node root) {
  Set<Node> visited;
  Set<Node> toNotify;  // nodes we want to notify

  Stack<Node> stack;
  stack.add(root);
  toNotify.add(root);  // we won't pop nodes from this until DFS is done
  while (!stack.empty()) {
    Node current = stack.pop();
    visited.add(current);
    for (Node x : neighbors_of(current)) {
      if (!visited.contains(x)) {
        stack.add(x);
        toNotify.add(x);
      }
    }
  }
  // Now issue notifications. toNotifyStack might contain duplicates (will never
  // happen in a tree but easily happens in a graph)
  Set<Node> notified;
  while (!toNotify.empty()) {
  Node n = toNotify.pop();
  if (!toNotify.contains(n)) {
    OnVisit(n);  // issue callback
    toNotify.add(n);
  }
}

It looks complicated but the extra logic needed for issuing notifications exists because you need to notify in reverse order of visit - DFS starts at root but notifies it last, unlike BFS which is very simple to implement.

For kicks, try following graph: nodes are s, t, v and w. directed edges are: s->t, s->v, t->w, v->w, and v->t. Run your own implementation of DFS and the order in which nodes should be visited must be: w, t, v, s A clumsy implementation of DFS would maybe notify t first and that indicates a bug. A recursive implementation of DFS would always reach w last.

Assuming you're viewing the output in a web browser you have at least two options:

1. Surround your text block with <pre> statements

2. Change your \n to an HTML <br> tag (<br/> will also do)

It should be as simple as using a list of receiving variables:

scanf("%i %i %i", &var1, &var2, &var3);

Instead of trying to learn vim, use a different easier editor (like nano, for example). As much as I like vim, I do not think using it in this case is the solution. It takes dedication and time to master it.

git config core.editor "nano"

I had a similar problem. I wanted to find a string in one column and put that value in another column in the same table. The select statement below finds the text inside the parens.

When I created the query in Access I selected all fields. On the SQL view for that query, I replaced the mytable.myfield for the field I wanted to have the value from inside the parens with

SELECT Left(Right(OtherField,Len(OtherField)-InStr((OtherField),"(")), 
            Len(Right(OtherField,Len(OtherField)-InStr((OtherField),"(")))-1) 

I ran a make table query. The make table query has all the fields with the above substitution and ends with INTO NameofNewTable FROM mytable

If you want the units h, min and sec for a duration you can use this:

public static String convertSeconds(int seconds) {
    int h = seconds/ 3600;
    int m = (seconds % 3600) / 60;
    int s = seconds % 60;
    String sh = (h > 0 ? String.valueOf(h) + " " + "h" : "");
    String sm = (m < 10 && m > 0 && h > 0 ? "0" : "") + (m > 0 ? (h > 0 && s == 0 ? String.valueOf(m) : String.valueOf(m) + " " + "min") : "");
    String ss = (s == 0 && (h > 0 || m > 0) ? "" : (s < 10 && (h > 0 || m > 0) ? "0" : "") + String.valueOf(s) + " " + "sec");
    return sh + (h > 0 ? " " : "") + sm + (m > 0 ? " " : "") + ss;
}

int seconds = 3661;
String duration = convertSeconds(seconds);

That's a lot of conditional operators. The method will return those strings:

0    -> 0 sec
5    -> 5 sec
60   -> 1 min
65   -> 1 min 05 sec
3600 -> 1 h
3601 -> 1 h 01 sec
3660 -> 1 h 01
3661 -> 1 h 01 min 01 sec
108000 -> 30 h

For a one-liner you can use the pingouin.linear_regression function (disclaimer: I am the creator of Pingouin), which works with uni/multi-variate regression using NumPy arrays or Pandas DataFrame, e.g:

import pingouin as pg
# Using a Pandas DataFrame `df`:
lm = pg.linear_regression(df[['x', 'z']], df['y'])
# Using a NumPy array:
lm = pg.linear_regression(X, y)

The output is a dataframe with the beta coefficients, standard errors, T-values, p-values and confidence intervals for each predictor, as well as the R^2 and adjusted R^2 of the fit.

Here's an example where the absence of b would throw a TypeError exception in Python 3.x

>>> f=open("new", "wb")
>>> f.write("Hello Python!")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'str' does not support the buffer interface

Adding a b prefix would fix the problem.

If you're like me and tried a few of these methods and are stuck at the point that you have the control in the toolbox and can draw it on the form but it disappears from the form and puts it down in the components, then simply edit the designer and add the following in the appropriate area of InitializeComponent() to make it visible:

this.Controls.Add(this.reportViewer1);

or

[ContainerControl].Controls.Add(this.reportViewer1);

You'll also need to make adjustments to the location and size manually after you've added the control.

Not a great answer for sure, but if you're stuck and just need to get work done for now until you have more time to figure it out, it should help.

Html Code:

 <select id="multiple" multiple="multiple" name="multiple">
  <option value=""> -- Select -- </option>
  <option value="1">Opt1</option>
  <option value="2">Opt2</option>
  <option value="3">Opt3</option>
  <option value="4">Opt4</option>
  <option value="5">Opt5</option>
 </select>   

JQuery Code:

$('#multiple :selected').each(function(i, sel){ 
    alert( $(sel).val() ); 

});

Hope it works

I am not sure I fully understand the problem, but pulling an existing branch is done like this (at least it works for me :)

git pull origin BRANCH

This is assuming that your local branch is created off of the origin/BRANCH.

To alter the password expiry policy for a certain user profile in Oracle first check which profile the user is using:

select profile from DBA_USERS where username = '<username>';

Then you can change the limit to never expire using:

alter profile <profile_name> limit password_life_time UNLIMITED;

If you want to previously check the limit you may use:

select resource_name,limit from dba_profiles where profile='<profile_name>';

I had a similar issue that was resolved with the following:

1. In Services.MSC click on the Log On tab and add the user with minimum privileges and password (on the service that is throwing the login error)
2. By Starting Sql Server to run as Administrator

If the user is a domain user use Domain username and password

you only need call in this way:

    <script type="text/javascript">     
        $(document).ready(function () {
            $(".mybuttonselector").postconfirm({ locale: {
                        title: 'title',

                        button: ['bt_0', 'bt_1'],
                        closeText: 'X'
                    }
                });
        });
    </script>

• Failed validation: 403 Forbidden ("The server understood the request, but is refusing to fulfill it"). Contrary to popular opinion, RFC2616 doesn't say "403 is only intended for failed authentication", but "403: I know what you want, but I won't do that". That condition may or may not be due to authentication.
• Trying to add a duplicate: 409 Conflict ("The request could not be completed due to a conflict with the current state of the resource.")

You should definitely give a more detailed explanation in the response headers and/or body (e.g. with a custom header - X-Status-Reason: Validation failed).

From wikipedia

In Java, all non-static methods are by default "virtual functions." Only methods marked with the keyword final, which cannot be overridden, along with private methods, which are not inherited, are non-virtual.

Here's yet another way to skin this cat, using a dictionary to map new values onto the keys in the list:

def map_values(row, values_dict):
    return values_dict[row]

values_dict = {'A': 1, 'B': 2, 'C': 3, 'D': 4}

df = pd.DataFrame({'INDICATOR': ['A', 'B', 'C', 'D'], 'VALUE': [10, 9, 8, 7]})

df['NEW_VALUE'] = df['INDICATOR'].apply(map_values, args = (values_dict,))

What's it look like:

df
Out[2]: 
  INDICATOR  VALUE  NEW_VALUE
0         A     10          1
1         B      9          2
2         C      8          3
3         D      7          4

This approach can be very powerful when you have many ifelse-type statements to make (i.e. many unique values to replace).

And of course you could always do this:

df['NEW_VALUE'] = df['INDICATOR'].map(values_dict)

But that approach is more than three times as slow as the apply approach from above, on my machine.

And you could also do this, using dict.get:

df['NEW_VALUE'] = [values_dict.get(v, None) for v in df['INDICATOR']]

The easiest solution is to use margin. This will also be responsive!

<div style="margin-right: auto">left</div>
<div style="margin-left: auto; margin-right:auto">center</div>
<div style="margin-left: auto">right</div>

This is sufficient...

xpath xhtmlfile.xhtml '/html/head/title/text()' > titleOfXHTMLPage.txt

Try moving ValueDate:

select sum(CASE  
             WHEN ValueDate > @startMonthDate THEN cash 
              ELSE 0 
           END) 
 from Table a
where a.branch = p.branch 
  and a.transID = p.transID

(reformatted for clarity)

You might also consider using '0' instead of NULL, as you are doing a sum. It works correctly both ways, but is maybe more indicitive of what your intentions are.

import json
data = json.load(open('/Users/laxmanjeergal/Desktop/json.json'))
jtopy=json.dumps(data) #json.dumps take a dictionary as input and returns a string as output.
dict_json=json.loads(jtopy) # json.loads take a string as input and returns a dictionary as output.
print(dict_json["shipments"])

Check out from dateutil.relativedelta import * for adding a specific amount of time to a date, you can continue to use timedelta for the simple stuff i.e.

use_date = use_date + datetime.timedelta(minutes=+10)
use_date = use_date + datetime.timedelta(hours=+1)
use_date = use_date + datetime.timedelta(days=+1)
use_date = use_date + datetime.timedelta(weeks=+1)

or you can start using relativedelta

use_date = use_date+relativedelta(months=+1)

use_date = use_date+relativedelta(years=+1)

for the last day of next month:

use_date = use_date+relativedelta(months=+1)
use_date = use_date+relativedelta(day=31)

Right now this will provide 29/02/2016

for the penultimate day of next month:

use_date = use_date+relativedelta(months=+1)
use_date = use_date+relativedelta(day=31)
use_date = use_date+relativedelta(days=-1)

last Friday of the next month:

use_date = use_date+relativedelta(months=+1, day=31, weekday=FR(-1))

2nd Tuesday of next month:

new_date = use_date+relativedelta(months=+1, day=1, weekday=TU(2))

As @mrroot5 points out dateutil's rrule functions can be applied, giving you an extra bang for your buck, if you require date occurences.
for example:
Calculating the last day of the month for 9 months from the last day of last month.
Then, calculate the 2nd Tuesday for each of those months.

from dateutil.relativedelta import *
from dateutil.rrule import *
from datetime import datetime
use_date = datetime(2020,11,21)

#Calculate the last day of last month
use_date = use_date+relativedelta(months=-1)
use_date = use_date+relativedelta(day=31)

#Generate a list of the last day for 9 months from the calculated date
x = list(rrule(freq=MONTHLY, count=9, dtstart=use_date, bymonthday=(-1,)))
print("Last day")
for ld in x:
    print(ld)

#Generate a list of the 2nd Tuesday in each of the next 9 months from the calculated date
print("\n2nd Tuesday")
x = list(rrule(freq=MONTHLY, count=9, dtstart=use_date, byweekday=TU(2)))
for tuesday in x:
    print(tuesday)

This is by no means an exhaustive list of what is available. Documentation is available here: https://dateutil.readthedocs.org/en/latest/

Your output is correct. Denote the white characters of " Hello" and " This" at the beginning.

Another issue is with your methodology. Use the Arrays.sort() method:

String[] strings = { " Hello ", " This ", "Is ", "Sorting ", "Example" };
Arrays.sort(strings);

Output:

 Hello
 This
Example
Is
Sorting

Here the third element of the array "is" should be "Is", otherwise it will come in last after sorting. Because the sort method internally uses the ASCII value to sort elements.

CSS

select.inpSelect {
  //Remove original arrows
  -webkit-appearance: none; 
  //Use png at assets/selectArrow.png for the arrow on the right
  //Set the background color to a BadAss Green color 
  background: url(assets/selectArrow.png) no-repeat right #BADA55;
}

If you just want the difference in years, there's:

SELECT EXTRACT(YEAR FROM date1) - EXTRACT(YEAR FROM date2) FROM mytable

Or do you want fractional years as well?

SELECT (date1 - date2) / 365.242199 FROM mytable

365.242199 is 1 year in days, according to Google.

With Modernizr (http://modernizr.com/), it can check for that functionality. Then you can tie it to the boolean it returns:

// does not trigger in Chrome, as the date Modernizr detects the date functionality.
if (!Modernizr.inputtypes.date) { 
    $("#opp-date").datepicker();
}

For Activity,

InputMethodManager imm = (InputMethodManager)getSystemService(INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);

For Fragments, use getActivity()

getActivity().getSystemService();

getActivity().getCurrentFocus();

InputMethodManager imm = (InputMethodManager)getActivity().getSystemService(INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(getActivity().getCurrentFocus().getWindowToken(), 0);

With ES6 you can do it with a simple one-liner

const If = ({children, show}) => show ? children : null

"show" is a boolean and you use this class by

<If show={true}> Will show </If>
<If show={false}> WON'T show </div> </If>

i personally have

alias ..='source ~/.bashrc'

in my bashrc, so that i can just use ".." to reload it.

In matplotlib grey colors can be given as a string of a numerical value between 0-1.
For example c = '0.1'

Then you can convert your third variable in a value inside this range and to use it to color your points.
In the following example I used the y position of the point as the value that determines the color:

from matplotlib import pyplot as plt

x = [1, 2, 3, 4, 5, 6, 7, 8, 9]
y = [125, 32, 54, 253, 67, 87, 233, 56, 67]

color = [str(item/255.) for item in y]

plt.scatter(x, y, s=500, c=color)

plt.show()

CTRL+SHIFT+C in Eclipse + StatET and Rstudio.

I'd like to propose another way that avoid recalling date command. It may be helpful in case if you have already gathered timestamps in %T date format:

ts_get_sec()
{
  read -r h m s <<< $(echo $1 | tr ':' ' ' )
  echo $(((h*60*60)+(m*60)+s))
}

start_ts=10:33:56
stop_ts=10:36:10

START=$(ts_get_sec $start_ts)
STOP=$(ts_get_sec $stop_ts)
DIFF=$((STOP-START))

echo "$((DIFF/60))m $((DIFF%60))s"

we can even handle millisecondes in the same way.

ts_get_msec()
{
  read -r h m s ms <<< $(echo $1 | tr '.:' ' ' )
  echo $(((h*60*60*1000)+(m*60*1000)+(s*1000)+ms))
}

start_ts=10:33:56.104
stop_ts=10:36:10.102

START=$(ts_get_msec $start_ts)
STOP=$(ts_get_msec $stop_ts)
DIFF=$((STOP-START))

min=$((DIFF/(60*1000)))
sec=$(((DIFF%(60*1000))/1000))
ms=$(((DIFF%(60*1000))%1000))

echo "${min}:${sec}.$ms"

Use !(window.ActiveXObject) && "ActiveXObject" in window to detect IE11 explicitly.

To detect any IE (pre-Edge, "Trident") version, use "ActiveXObject" in window instead.

I prefer to use an extension method to get the scripts object:

public static IJavaScriptExecutor Scripts(this IWebDriver driver)
{
    return (IJavaScriptExecutor)driver;
}

Used as this:

driver.Scripts().ExecuteScript("some script");

Whatever goes to softmax is logit, this is what J. Hinton repeats in coursera videos all the time.

I've found the answer (by further examining the Sublime 2 config files structure):

I was to open

~/.config/sublime-text-2/Packages/Scala/Scala.tmLanguage

And edit it to add sbt (the extension of files I want to be opened as Scala code files) to the array after the fileTypes key:

<dict>
  <key>bundleUUID</key>
  <string>452017E8-0065-49EF-AB9D-7849B27D9367</string>
  <key>fileTypes</key>
  <array>
    <string>scala</string>
    <string>sbt</string>
  <array>
  ...

PS: May there be a better way, something like a right place to put my customizations (insted of modifying packages themselves), I'd still like to know.

I have created this Plunker based on your example that updates the object equal to newItem.id

Here's the snippet of my functions:

showUpdatedItem(newItem){
    let updateItem = this.itemArray.items.find(this.findIndexToUpdate, newItem.id);

    let index = this.itemArray.items.indexOf(updateItem);


    this.itemArray.items[index] = newItem;

  }

  findIndexToUpdate(newItem) { 
        return newItem.id === this;
  }

Hope this helps.

With Google Guava's Ints class, your method can be changed to:

public static int safeLongToInt(long l) {
    return Ints.checkedCast(l);
}

From the linked docs:

checkedCast

public static int checkedCast(long value)

Returns the int value that is equal to value, if possible.

Parameters: value - any value in the range of the int type

Returns: the int value that equals value

Throws: IllegalArgumentException - if value is greater than Integer.MAX_VALUE or less than Integer.MIN_VALUE

Incidentally, you don't need the safeLongToInt wrapper, unless you want to leave it in place for changing out the functionality without extensive refactoring of course.

I prefer option two because it clearly shows the list item as the possessor of that nested list. I would always lean towards semantically sound HTML.

The Facebook API watches for the FB._apiKey so you can watch for this before calling your own application of the API with something like:

window.fbAsyncInit = function() {
  FB.init({
    //...your init object
  });
  function myUseOfFB(){
    //...your FB API calls
  };
  function FBreadyState(){
    if(FB._apiKey) return myUseOfFB();
    setTimeout(FBreadyState, 100); // adjust time as-desired
  };
  FBreadyState();
}; 

Not sure this makes a difference but in my case--because I wanted to be sure the UI was ready--I've wrapped the initialization with jQuery's document ready (last bit above):

  $(document).ready(FBreadyState);

Note too that I'm NOT using async = true to load Facebook's all.js, which in my case seems to be helping with signing into the UI and driving features more reliably.

CMake favours passing the full path to link libraries, so assuming libbingitup.a is in ${CMAKE_SOURCE_DIR}, doing the following should succeed:

add_executable(main main.cpp)
target_link_libraries(main ${CMAKE_SOURCE_DIR}/libbingitup.a)

Your project is missing the support library from the SDK.

If you have no installed them, just right click on the project > Android Tools > Install support library.

Then, just import into workspace, as an Android project, android-support-v7-appcompat, located into ${android-sdk-path}/extras/android/support/v7

And finally, right click in the Android project > Properties > Android Tab. Push the Add button and add the support project "android-support-v7-appcompat" as dependency.

Clean your project and the must compile and work properly.

firstly u have to import numpy library (refer code for making a numpy array) shape only gives the output only if the variable is attribute of numpy library .in other words it must be a np.array or any other data structure of numpy. Eg.

`>>> import numpy
>>> a=numpy.array([[1,1],[1,1]])
>>> a.shape
(2, 2)`

Any class which extends Exception class will be a user defined Checked exception class where as any class which extends RuntimeException will be Unchecked exception class. as mentioned in User defined exception are checked or unchecked exceptions So, not throwing the checked exception(be it user-defined or built-in exception) gives compile time error.

Checked exception are the exceptions that are checked at compile time.

Unchecked exception are the exceptions that are not checked at compiled time

As of C++20, yes.

As of C++17, you can use string_view:

constexpr std::string_view sv = "hello, world";

A string_view is a string-like object that acts as an immutable, non-owning reference to any sequence of char objects.

Once had this issue, thought it reasonable to share how I resolved it;

I think the way to do that in php is to use the header function as:

header ("Location: exampleFile.php");

You could just enclose that header file in an if statement so that it redirects only when a certain condition is met, as in:

if (isset($_POST['submit'])){   header("Location: exampleFile.php")   }

Hope that helps.

OR condition in #ifdef

#if defined LINUX || defined ANDROID
// your code here
#endif /* LINUX || ANDROID */

or-

#if defined(LINUX) || defined(ANDROID)
// your code here
#endif /* LINUX || ANDROID */

Both above are the same, which one you use simply depends on your taste.

P.S.: #ifdef is simply the short form of #if defined, however, does not support complex condition.

Further-

• AND: #if defined LINUX && defined ANDROID
• XOR: #if defined LINUX ^ defined ANDROID

The way I do it is to do a Topological Sort, counting the number of vertices visited. If that number is less than the total number of vertices in the DAG, you have a cycle.

Just right click on that column and select properties and write getdate()in Default value or binding.like image:

If you want do it in CodeFirst in EF you should add this attributes befor of your column definition:

[Databasegenerated(Databaseoption.computed)]

this attributes can found in System.ComponentModel.Dataannotion.Schema.

In my opinion first one is better:))

Node.js 8.0.0 includes a new util.promisify() API that allows standard Node.js callback style APIs to be wrapped in a function that returns a Promise. An example use of util.promisify() is shown below.

const fs = require('fs');
const util = require('util');

const readFile = util.promisify(fs.readFile);

readFile('/some/file')
  .then((data) => { /** ... **/ })
  .catch((err) => { /** ... **/ });

If column A contains the amounts to be reimbursed, and column B contains the "yes/no" indicating whether the reimbursement has been made, then either of the following will work, though the first option is recommended:

=SUMIF(B:B,"No",A:A)

or

=SUMIFS(A:A,B:B,"No")

Here is an example that will display the amounts paid and outstanding for a small set of sample data.

 A         B            C                   D
 Amount    Reimbursed?  Total Paid:         =SUMIF(B:B,"Yes",A:A)
 $100      Yes          Total Outstanding:  =SUMIF(B:B,"No",A:A)
 $200      No           
 $300      No
 $400      Yes
 $500      No

Be careful of span!

myspan.styles.width='100px' doesn't want to work.

Change the span to a div.

The main concept of partial view is returning the HTML code rather than going to the partial view it self.

[HttpGet]
public ActionResult Calendar(int year)
{
    var dates = new List<DateTime>() { /* values based on year */ };
    HolidayViewModel model = new HolidayViewModel {
        Dates = dates
    };
    return PartialView("HolidayPartialView", model);
}

this action return the HTML code of the partial view ("HolidayPartialView").

To refresh partial view replace the existing item with the new filtered item using the jQuery below.

$.ajax({
                url: "/Holiday/Calendar",
                type: "GET",
                data: { year: ((val * 1) + 1) }
            })
            .done(function(partialViewResult) {
                $("#refTable").html(partialViewResult);
            });

You don't need a custom control, just put your container in a border element:

<Border BorderBrush="#FF000000" BorderThickness="1" CornerRadius="8">
   <Grid/>
</Border>

You can replace the <Grid/> with any of the layout containers...

// array of primitives:
int[] intArray = new int[] {1, 2, 3, 4, 5};

System.out.println(Arrays.toString(intArray));

output: [1, 2, 3, 4, 5]

// array of object references:
String[] strArray = new String[] {"John", "Mary", "Bob"};

System.out.println(Arrays.toString(strArray));

output: [John, Mary, Bob]

There are three approaches:

1. DECLARE
2. SET -- Microsoft Recommended approach
3. SELECT

Below query details the advantage and disadvantage of each:

-- First way, 
DECLARE @test int = (SELECT 1)
       , @test2 int = (SELECT a from (values (1),(2)) t(a)) -- throws error

-- advantage: declare and set in the same place
-- Disadvantage: can be used only during declaration. cannot be used later

-- Second way
DECLARE @test int  
       , @test2 int 

SET @test = (select 1)
SET @test2 = (SELECT a from (values (1),(2)) t(a)) -- throws error

-- Advantage: ANSI standard. 
-- Disadvantage: cannot set more than one variable at a time

-- Third way
DECLARE @test int, @test2 int 
SELECT @test = (select 1)
      ,@test2 = (SELECT a from (values (1),(2)) t(a)) -- throws error

-- Advantage: Can set more than one variable at a time
-- Disadvantage: Not ANSI standard

I tried experimenting with the answers given. My personal finding came out to be:

git rm -r --cached .

And then

git add .

This seemed to make my working directory nice and clean. You can put your fileName in place of the dot.

Here is a way to solve the problem if your public repo on github.com is working, but your local repo is corrupt. Be aware that you will loose all the commits you've done in the local repo.

Alright, so I have one repo locally that is giving me this object empty error, and the same repo on github.com, but without this error. So what I simply did was to clone the repo that is working from github, and then copied everything from the corrupt repo (except the .git folder), and paste it the cloned repo that is working.

This may not be a practical solution (since you delete the local commits), however, you maintain the code and a repaired version control.

Remember to back-up before applying this approach.

Example using std::vector

#include <iostream>
#include <string>
#include <algorithm>
#include <vector>

int main()
{
    /// Initilaize vector using intitializer list ( requires C++11 )
    std::vector<std::string> names = {"john", "bobby", "dear", "test1", "catherine", "nomi", "shinta", "martin", "abe", "may", "zeno", "zack", "angeal", "gabby"};

    // Sort names using std::sort
    std::sort(names.begin(), names.end() );

    // Print using range-based and const auto& for ( both requires C++11 )
    for(const auto& currentName : names)
    {
        std::cout << currentName << std::endl;
    }

    //... or by using your orignal for loop ( vector support [] the same way as plain arrays )
    for(int y = 0; y < names.size(); y++)
    {
       std:: cout << names[y] << std::endl; // you were outputting name[z], but only increasing y, thereby only outputting element z ( 14 )
    }
    return 0;

}

http://ideone.com/Q9Ew2l

This completely avoids using plain arrays, and lets you use the std::sort function. You might need to update you compiler to use the = {...} You can instead add them by using vector.push_back("name")

They are both data formats for hierarchical data, so while the syntax is quite different, the structure is similar. Example:

JSON:

{
  "persons": [
    {
      "name": "Ford Prefect",
      "gender": "male"
    },
    {
      "name": "Arthur Dent",
      "gender": "male"
    },
    {
      "name": "Tricia McMillan",
      "gender": "female"
    }
  ]
}

XML:

<persons>
  <person>
    <name>Ford Prefect</name>
    <gender>male</gender>
  </person>
  <person>
    <name>Arthur Dent</name>
    <gender>male</gender>
  </person>
  <person>
    <name>Tricia McMillan</name>
    <gender>female</gender>
  </person>
</persons>

The XML format is more advanced than shown by the example, though. You can for example add attributes to each element, and you can use namespaces to partition elements. There are also standards for defining the format of an XML file, the XPATH language to query XML data, and XSLT for transforming XML into presentation data.

The XML format has been around for some time, so there is a lot of software developed for it. The JSON format is quite new, so there is a lot less support for it.

While XML was developed as an independent data format, JSON was developed specifically for use with Javascript and AJAX, so the format is exactly the same as a Javascript literal object (that is, it's a subset of the Javascript code, as it for example can't contain expressions to determine values).

Why not just:

IF object_id('YourFunctionName', 'FN') IS NOT NULL
BEGIN
    DROP FUNCTION [dbo].[YourFunctionName]
END
GO

The second argument of object_id is optional, but can help to identify the correct object. There are numerous possible values for this type argument, particularly:

• FN : Scalar function
• IF : Inline table-valued function
• TF : Table-valued-function
• FS : Assembly (CLR) scalar-function
• FT : Assembly (CLR) table-valued function

It worth mentioning that the build time will be increased for VS 2015 users after:

Install-Package Microsoft.Net.Compilers

Those who are using VS 2015 and have to keep this package in their projects can fix increased build time.

Edit file packages\Microsoft.Net.Compilers.1.2.2\build\Microsoft.Net.Compilers.props and clean it up. The file should look like:

<Project DefaultTargets="Build" 
         xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
</Project>

Doing so forces a project to be built as it was before adding Microsoft.Net.Compilers package

And in Bash

 line1=`tail -3 /opt/Scripts/wowzaDataSync.log | grep "AmazonHttpClient" | head -1`
 vpid=`ps -ef|  grep wowzaDataSync | grep -v grep  | awk '{print $2}'`
 echo "-------->"${line1}
    if [ -z $line1 ] && [ ! -z $vpid ]
    then
            echo `date --date "NOW" +%Y-%m-%d` `date --date "NOW" +%H:%M:%S` :: 
            "Process Is Working Fine"
    else
            echo `date --date "NOW" +%Y-%m-%d` `date --date "NOW" +%H:%M:%S` :: 
            "Prcess Hanging Due To Exception With PID :"${pid}
   fi

OR in Bash

line1=`tail -3 /opt/Scripts/wowzaDataSync.log | grep "AmazonHttpClient" | head -1`
vpid=`ps -ef|  grep wowzaDataSync | grep -v grep  | awk '{print $2}'`
echo "-------->"${line1}
   if [ -z $line1 ] || [ ! -z $vpid ]
    then
            echo `date --date "NOW" +%Y-%m-%d` `date --date "NOW" +%H:%M:%S` :: 
            "Process Is Working Fine"
    else
            echo `date --date "NOW" +%Y-%m-%d` `date --date "NOW" +%H:%M:%S` :: 
            "Prcess Hanging Due To Exception With PID :"${pid}
  fi

Short ways to write lines of text to a file in R could be realised with cat or writeLines as already shown in many answers. Some of the shortest possibilities might be:

cat("Hello\nWorld", file="output.txt")
writeLines("Hello\nWorld", "output.txt")

In case you don't like the "\n" you could also use the following style:

cat("Hello
World", file="output.txt")

writeLines("Hello
World", "output.txt")

While writeLines adds a newline at the end of the file what is not the case for cat. This behaviour could be adjusted by:

writeLines("Hello\nWorld", "output.txt", sep="") #No newline at end of file
cat("Hello\nWorld\n", file="output.txt") #Newline at end of file
cat("Hello\nWorld", file="output.txt", sep="\n") #Newline at end of file

But main difference is that cat uses R objects and writeLines a character vector as argument. So writing out e.g. the numbers 1:10 needs to be casted for writeLines while it can be used as it is in cat:

cat(1:10)
writeLines(as.character(1:10))

and cat can take many objects but writeLines only one vector:

cat("Hello", "World", sep="\n")
writeLines(c("Hello", "World"))

You didn't paste the part where you call startActivity, that's the interesting part.

You might be calling startActivity in a Service context, or in an Application context.

Print "this" to log cat before making the startActivity call, and see what it refers to, it's sometimes a case of using an inner "this" accidentally.

My solution. The JSONServer is a class I wrote for running an HttpListener server in a console window.

class Program
{
    public static JSONServer srv = null;

    static void Main(string[] args)
    {
        Console.WriteLine("NLPS Core Server");

        srv = new JSONServer(100);
        srv.Start();

        InputLoopProcessor();

        while(srv.IsRunning)
        {
            Thread.Sleep(250);
        }

    }

    private static async Task InputLoopProcessor()
    {
        string line = "";

        Console.WriteLine("Core NLPS Server: Started on port 8080. " + DateTime.Now);

        while(line != "quit")
        {
            Console.Write(": ");
            line = Console.ReadLine().ToLower();
            Console.WriteLine(line);

            if(line == "?" || line == "help")
            {
                Console.WriteLine("Core NLPS Server Help");
                Console.WriteLine("    ? or help: Show this help.");
                Console.WriteLine("    quit: Stop the server.");
            }
        }
        srv.Stop();
        Console.WriteLine("Core Processor done at " + DateTime.Now);

    }
}

$cfg['Servers'][$i]['AllowNoPassword'] = false;

Quote: I would like to know how to display the div in the middle of the screen, whether user has scrolled up/down.

Change

position: absolute;

To

position: fixed;

W3C specifications for position: absolute and for position: fixed.

Moment js solution to this is

var d = new Date(new Date().setHours(0,0,0,0));
m.add(m.utcOffset(), 'm')
m.toDate().toISOString()
// output "2019-07-18T00:00:00.000Z"

Call like this

my_function ("", options);

Having used React to build an app now, I'd like to share some thoughts to this question I asked half a year ago.

I recommend you to read

• Thinking in React
• Flux

The first post is extremely helpful to understanding how you should structure your React app.

Flux answers the question why should you structure your React app this way (as opposed to how to structure it). React is only 50% of the system, and with Flux you get to see the whole picture and see how they constitute a coherent system.

Back to the question.

As for my first solution, it is totally OK to let the handler go the reverse direction, as the data is still going single-direction.

However, whether letting a handler trigger a setState in P can be right or wrong depending on your situation.

If the app is a simple Markdown converter, C1 being the raw input and C2 being the HTML output, it's OK to let C1 trigger a setState in P, but some might argue this is not the recommended way to do it.

However, if the app is a todo list, C1 being the input for creating a new todo, C2 the todo list in HTML, you probably want to handler to go two level up than P -- to the dispatcher, which let the store update the data store, which then send the data to P and populate the views. See that Flux article. Here is an example: Flux - TodoMVC

Generally, I prefer the way described in the todo list example. The less state you have in your app the better.

The reference is the unique identifier for the object. I don't know of any way of converting this into anything like a string etc. The value of the reference will change during compaction (as you've seen), but every previous value A will be changed to value B, so as far as safe code is concerned it's still a unique ID.

If the objects involved are under your control, you could create a mapping using weak references (to avoid preventing garbage collection) from a reference to an ID of your choosing (GUID, integer, whatever). That would add a certain amount of overhead and complexity, however.

This suggestion is based on pixel manipulation in canvas 2d context.

From MDN:

You can directly manipulate pixel data in canvases at the byte level

To manipulate pixels we'll use two functions here - getImageData and putImageData.

getImageData usage:

var myImageData = context.getImageData(left, top, width, height);

The putImageData syntax:

context.putImageData(myImageData, x, y); 

Where context is your canvas 2d context, and x and y are the position on the canvas.

So to get red green blue and alpha values, we'll do the following:

var r = imageData.data[((x*(imageData.width*4)) + (y*4))];
var g = imageData.data[((x*(imageData.width*4)) + (y*4)) + 1];
var b = imageData.data[((x*(imageData.width*4)) + (y*4)) + 2];
var a = imageData.data[((x*(imageData.width*4)) + (y*4)) + 3];

Where x is the horizontal offset, y is the vertical offset.

The code making image half-transparent:

var canvas = document.getElementById('myCanvas');
var c = canvas.getContext('2d');
var img = new Image();
img.onload  = function() {
   c.drawImage(img, 0, 0);
   var ImageData = c.getImageData(0,0,img.width,img.height);
   for(var i=0;i<img.height;i++)
      for(var j=0;j<img.width;j++)
         ImageData.data[((i*(img.width*4)) + (j*4) + 3)] = 127;//opacity = 0.5 [0-255]
   c.putImageData(ImageData,0,0);//put image data back

You can make you own "shaders" - see full MDN article here

You can also simply set your pandas column as list of id values with length same as of dataframe.

df['New_ID'] = range(880, 880+len(df))

Generally means that its a file that needs to be included and does not make standalone script in itself.

This is a convention not a programming technique.

Although if your web server is not configured properly it could expose files with extensions like .inc.

If you are accessing a plain HTML form, it has to be submitted to the server via a submit button (or via javascript post). This usually means that your form definition will look like this (I'm going off of memory, make sure you check the html elements are correct):

<form method="POST" action="page.aspx">

<input id="customerName" name="customerName" type="Text" />
<input id="customerPhone" name="customerPhone" type="Text" />
<input value="Save" type="Submit" />

</form>

You should be able to access the customerName and customerPhone data like this:

string n = String.Format("{0}", Request.Form["customerName"]);

If you have method="GET" in the form (not recommended, it messes up your URL space), you will have to access the form data like this:

string n = String.Format("{0}", Request.QueryString["customerName"]);

This of course will only work if the form was 'Posted', 'Submitted', or done via a 'Postback'. (i.e. somebody clicked the 'Save' button, or this was done programatically via javascript.)

Also, keep in mind that accessing these elements in this manner can only be done when you are not using server controls (i.e. runat="server"), with server controls the id and name are different.

I'm experiencing some problems using apply() instead commit(). As stated before in other responses, the apply() is asynchronous. I'm getting the problem that the changes formed to a "string set" preference are never written to the persistent memory.

It happens if you "force detention" of the program or, in the ROM that I have installed on my device with Android 4.1, when the process is killed by the system due to memory necessities.

I recommend to use "commit()" instead "apply()" if you want your preferences alive.

You are almost certainly using a different version of the class at runtime to the one you expect. In particular, the runtime class would be different to the one you've compiled against (else this would have caused a compile-time error) - has that method ever been private? Do you have old versions of the classes/jars on your system anywhere?

As the javadocs for IllegalAccessError state,

Normally, this error is caught by the compiler; this error can only occur at run time if the definition of a class has incompatibly changed.

I'd definitely look at your classpath and check whether it holds any surprises.

typedef struct{
     char name[30];
     char surname[30];
     int age;
} data;

defines that data should be a block of memory that fits 60 chars plus 4 for the int (see note)

[----------------------------,------------------------------,----]
 ^ this is name              ^ this is surname              ^ this is age

This allocates the memory on the stack.

data s1;

Assignments just copies numbers, sometimes pointers.

This fails

s1.name = "Paulo";

because the compiler knows that s1.name is the start of a struct 64 bytes long, and "Paulo" is a char[] 6 bytes long (6 because of the trailing \0 in C strings)
Thus, trying to assign a pointer to a string into a string.

To copy "Paulo" into the struct at the point name and "Rossi" into the struct at point surname.

memcpy(s1.name,    "Paulo", 6);
memcpy(s1.surname, "Rossi", 6);
s1.age = 1;

You end up with

[Paulo0----------------------,Rossi0-------------------------,0001]

strcpy does the same thing but it knows about \0 termination so does not need the length hardcoded.

Alternatively you can define a struct which points to char arrays of any length.

typedef struct {
  char *name;
  char *surname;
  int age;
} data;

This will create

[----,----,----]

This will now work because you are filling the struct with pointers.

s1.name = "Paulo";
s1.surname = "Rossi";
s1.age = 1;

Something like this

[---4,--10,---1]

Where 4 and 10 are pointers.

Note: the ints and pointers can be different sizes, the sizes 4 above are 32bit as an example.

Building off of Ben Blank's answer, the only way that I got this to validate in the w3 validator was like so:

<img src="/./.:0" alt="">`

This is my solution that works nicely for opening "ugly" HTML in a nicely spaced way:

vim fileIn.html -c "set sw=2 | %s/>/>\r/ | execute 'normal gg=G' | set nohlsearch | g/^\\s*\$/d"

• The sw command is because my default is 4, which is too high for HTML.
• The next part adds a newline (Vim thinks it's a carriage return, sigh) after each element (>).
• Then re-indent the entire file with =.
• Then unhighlight > (since I have set hlsearch in my vimrc).
• Then remove all empty/whitespace-only lines (see "Vim delete blank lines" for more, also this is double-escaped because it's in the shell).

You can even add | wq! fileOut.html to the end if you don't want to enter Vim at all, but just clean up the file.

You don't need CSS for this.

     <img src="abc"/>

now with link:

     <a href="#myLink"><img src="abc"/></a>

Or with jquery, later on, you can use the wrap property, see these questions answer:

how to add a link to an image using jquery?

Did you try with strip() :

listOfNum = ['231512-n','1209123100000-n00000','alphanumeric0000', 'alphanumeric']
print [item.strip('0') for item in listOfNum]

>>> ['231512-n', '1209123100000-n', 'alphanumeric', 'alphanumeric']

This command might come in handy. This will not record the command that is executed

history -d $((HISTCMD-1)) && <Your Command Here>

set up a new postgresql server and replace its data folder with the files from your external disk.

You will then be able to start that postgresql server up and retrieve the data using pg_dump (pg_dump -s for the schema-only as mentioned)

This doesn't directly answer the question but can be very useful, especially if you want something like all the numeric columns except for your id column and dependent variable.

numeric_cols <- sapply(dataframe, is.numeric) %>% which %>% 
                   names %>% setdiff(., c("id_variable", "dep_var"))

dataframe %<>% dplyr::mutate_at(numeric_cols, function(x) your_function(x))

Generally Server JDK version will be lower than the deployed application (built with higher jdk version)

I discovered that SequenceEqual is not the most efficient way to compare two lists of strings (initially from http://www.dotnetperls.com/sequenceequal).

I wanted to test this myself so I created two methods:

    /// <summary>
    /// Compares two string lists using LINQ's SequenceEqual.
    /// </summary>
    public bool CompareLists1(List<string> list1, List<string> list2)
    {
        return list1.SequenceEqual(list2);
    }

    /// <summary>
    /// Compares two string lists using a loop.
    /// </summary>
    public bool CompareLists2(List<string> list1, List<string> list2)
    {
        if (list1.Count != list2.Count)
            return false;

        for (int i = 0; i < list1.Count; i++)
        {
            if (list1[i] != list2[i])
                return false;
        }

        return true;
    }

The second method is a bit of code I encountered and wondered if it could be refactored to be "easier to read." (And also wondered if LINQ optimization would be faster.)

As it turns out, with two lists containing 32k strings, over 100 executions:

• Method 1 took an average of 6761.8 ticks
• Method 2 took an average of 3268.4 ticks

I usually prefer LINQ for brevity, performance, and code readability; but in this case I think a loop-based method is preferred.

Edit:

I recompiled using optimized code, and ran the test for 1000 iterations. The results still favor the loop (even more so):

• Method 1 took an average of 4227.2 ticks
• Method 2 took an average of 1831.9 ticks

Tested using Visual Studio 2010, C# .NET 4 Client Profile on a Core i7-920

Well, I think that there are simple solutions than mentioned here on this page! first of all, let's make an example:

You have 1 DIV and want to hide thas DIV on Desktop and show on Mobile (or vice versa). So, let's presume that the DIV position placed in the Head section and named as header_div.

The global code in your CSS file will be: (for the same DIV):

.header_div {
    display: none;
}

@media all and (max-width: 768px){
.header_div {
    display: block;
}
}

So simple and no need to make 2 div's one for desktop and the other for mobile.

Hope this helps.

Thank you.

Use strftime in the standard POSIX module. The arguments to strftime in Perl’s binding were designed to align with the return values from localtime and gmtime. Compare

strftime(fmt, sec, min, hour, mday, mon, year, wday = -1, yday = -1, isdst = -1)

with

my          ($sec,$min,$hour,$mday,$mon,$year,$wday,     $yday,     $isdst) = gmtime(time);

Example command-line use is

$ perl -MPOSIX -le 'print strftime "%F %T", localtime $^T'

or from a source file as in

use POSIX;

print strftime "%F %T", localtime time;

Some systems do not support the %F and %T shorthands, so you will have to be explicit with

print strftime "%Y-%m-%d %H:%M:%S", localtime time;

or

print strftime "%Y-%m-%d %H:%M:%S", gmtime time;

Note that time returns the current time when called whereas $^T is fixed to the time when your program started. With gmtime, the return value is the current time in GMT. Retrieve time in your local timezone with localtime.

I am using angular 5 and you can simply check the status property of your form using FormGroup e.g.

this.form = new FormGroup({
      firstName: new FormControl('', [Validators.required, validateName]),
      lastName: new FormControl('', [Validators.required, validateName]),
      email: new FormControl('', [Validators.required, validateEmail]),
      dob: new FormControl('', [Validators.required, validateDate])
    });

this.form.status would be "INVALID" unless all the fields pass all the validation rules.

The best part is that it detects changes in real-time.

Try the following

Dictionary<int, DateTime> existingItems = 
    (from ObjType ot in TableObj).ToDictionary(x => x.Key);

Or the fully fledged type inferenced version

var existingItems = TableObj.ToDictionary(x => x.Key);

Following solution is working fine.

HTML:

<table>
  <tr>
    <td>
      <input type="button" value="Delete Row" onclick="SomeDeleteRowFunction(this);">
    </td>
  </tr>
  <tr>
    <td>
      <input type="button" value="Delete Row" onclick="SomeDeleteRowFunction(this);">
    </td>
  </tr>
  <tr>
    <td>
      <input type="button" value="Delete Row" onclick="SomeDeleteRowFunction(this);">
    </td>
  </tr>
</table>

JQuery:

function SomeDeleteRowFunction(btndel) {
    if (typeof(btndel) == "object") {
        $(btndel).closest("tr").remove();
    } else {
        return false;
    }
}

Use onKeyDown event, and inside that check the key code of the key pressed by user. Key code of Enter key is 13, check the code and put the logic there.

TL;DR; Are you even on the correct repository?

My story is bit funny but I thought it can happen with someone who might be having a similar scenario so sharing it here.

Actually on my machine, I had two separate git repositories repo1 and repo2 configured in the same root directory named source. These two repositories are essentially the repositories of two products I work off and on in my company. Now the thing is that as a standard guideline, the directory structure of source code of all the products is exactly the same in my company.

So without realizing I modified an exactly same named file in repo2 which I was supposed to change in repo1. So, I just kept running command git status on repo1 and it kept giving the same message

On branch master

nothing to commit, working directory clean

for half an hour. Then colleague of mine observed it as independent pair of eyes and brought this thing to my notice that I was in wrong but very similar looking repository. The moment I switched to repo1 Git started noticing the changed files.

Not so common case. But you never know!

This should do it:

You can use "break" to break the loop, which will not allow the loop to process more conditions

In my case, I restart the computer and enable the virtualization technology in BIOS. Then start up computer, open VM Virtual Box, choose a virtual device, go to Settings-General-Basic-Version, choose ubuntu(64 bit), save the settings then start virtual device from genymotion, everything is ok now.

If you are not wanting to use async you can add .Result to force the code to execute synchronously:

private string GetResponseString(string text)
{
    var httpClient = new HttpClient();

    var parameters = new Dictionary<string, string>();
    parameters["text"] = text;

    var response = httpClient.PostAsync(BaseUri, new FormUrlEncodedContent(parameters)).Result;
    var contents = response.Content.ReadAsStringAsync().Result;

    return contents;

Full steps to get current location, and avoid Last Known Location nullability.

According to official documentation, Last Known Location could be Null in case of:

• Location is turned off in the device settings. As it clears the cache.
• The device never recorded its location. (New device)
• Google Play services on the device has restarted.

In this case, you should requestLocationUpdates and receive the new location on the LocationCallback.

By the following steps your last known Location never null.

Pre-requisite: EasyPermission library

Step 1: In manifest file add this permission

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

Step 2:

    override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    //Create location callback when it's ready.
    createLocationCallback()

    //createing location request, how mant request would be requested.
    createLocationRequest()

    //Build check request location setting request
    buildLocationSettingsRequest()

    //FusedLocationApiClient which includes location 
    mFusedLocationClient = LocationServices.getFusedLocationProviderClient(this)
    //Location setting client
    mSettingsClient = LocationServices.getSettingsClient(this)

    //Check if you have ACCESS_FINE_LOCATION permission
    if (!EasyPermissions.hasPermissions(
            this@MainActivity,
            Manifest.permission.ACCESS_FINE_LOCATION)) {
        requestPermissionsRequired()
    }
    else{
        //If you have the permission we should check location is opened or not
        checkLocationIsTurnedOn()
    }

}

Step 3: Create required functions to be called in onCreate()

private fun requestPermissionsRequired() {
    EasyPermissions.requestPermissions(
        this,
        getString(R.string.location_is_required_msg),
        LOCATION_REQUEST,
        Manifest.permission.ACCESS_FINE_LOCATION
    )
}

private fun createLocationCallback() {
    //Here the location will be updated, when we could access the location we got result on this callback.
    mLocationCallback = object : LocationCallback() {
        override fun onLocationResult(locationResult: LocationResult) {
            super.onLocationResult(locationResult)
            mCurrentLocation = locationResult.lastLocation
        }
    }
}

private fun buildLocationSettingsRequest() {
    val builder = LocationSettingsRequest.Builder()
    builder.addLocationRequest(mLocationRequest!!)
    mLocationSettingsRequest = builder.build()
    builder.setAlwaysShow(true)
}

private fun createLocationRequest() {
    mLocationRequest = LocationRequest.create()
    mLocationRequest!!.interval = 0
    mLocationRequest!!.fastestInterval = 0
    mLocationRequest!!.numUpdates = 1
    mLocationRequest!!.priority = LocationRequest.PRIORITY_HIGH_ACCURACY
}

public fun checkLocationIsTurnedOn() { // Begin by checking if the device has the necessary location settings.
    mSettingsClient!!.checkLocationSettings(mLocationSettingsRequest)
        .addOnSuccessListener(this) {
            Log.i(TAG, "All location settings are satisfied.")
            startLocationUpdates()
        }
        .addOnFailureListener(this) { e ->
            val statusCode = (e as ApiException).statusCode
            when (statusCode) {
                LocationSettingsStatusCodes.RESOLUTION_REQUIRED -> {
                    try {
                        val rae = e as ResolvableApiException
                        rae.startResolutionForResult(this@MainActivity, LOCATION_IS_OPENED_CODE)
                    } catch (sie: IntentSender.SendIntentException) {
                    }
                }
                LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE -> {
                    mRequestingLocationUpdates = false
                }
            }
        }
}

private fun startLocationUpdates() {
    mFusedLocationClient!!.requestLocationUpdates(
        mLocationRequest,
        mLocationCallback, null
    )
}

Step 4:

Handle callbacks in onActivityResult() after ensuring the location is opened or the user accepts to open it in.

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    when (requestCode) {
        LOCATION_IS_OPENED_CODE -> {
            if (resultCode == AppCompatActivity.RESULT_OK) {
                Log.d(TAG, "Location result is OK")
            } else {
                activity?.finish()
            }
        }
}

Step 5: Get last known location from FusedClientApi

override fun onMapReady(map: GoogleMap) {
    mMap = map
    mFusedLocationClient.lastLocation.addOnSuccessListener {
        if(it!=null){
            locateUserInMap(it)
        }
    }

}
   private fun locateUserInMap(location: Location) {
    showLocationSafetyInformation()
    if(mMap!=null){
        val currentLocation = LatLng(location.latitude,location.longitude )
        addMarker(currentLocation)
    }
}


private fun addMarker(currentLocation: LatLng) {
    val cameraUpdate = CameraUpdateFactory.newLatLng(currentLocation)
    mMap?.clear()
    mMap?.addMarker(
        MarkerOptions().position(currentLocation)
            .title("Current Location")
    )
    mMap?.moveCamera(cameraUpdate)
    mMap?.animateCamera(cameraUpdate)
    mMap?.setMinZoomPreference(14.0f);
}

I hope this would help.

Happy Coding

If you are creating a container from an image and like to expose multiple ports (not publish) you can use the following command:

docker create --name `container name` --expose 7000 --expose 7001 `image name`

Now, when you start this container using the docker start command, the configured ports above will be exposed.

I've searched solution to similar problem and maybe my way will help You and anybody who face with it.

I used SelectedValuePath="id" in XAML DataGrid definition, and programaticaly only thing I have to do is set DataGrid.SelectedValue to desired value.

I know this solution has pros and cons, but in specific case is fast and easy.

import argparse
parser = argparse.ArgumentParser()
parser.add_argument('--example', nargs='?', const=1, type=int)
args = parser.parse_args()
print(args)

% test.py 
Namespace(example=None)
% test.py --example
Namespace(example=1)
% test.py --example 2
Namespace(example=2)

• nargs='?' means 0-or-1 arguments
• const=1 sets the default when there are 0 arguments
• type=int converts the argument to int

If you want test.py to set example to 1 even if no --example is specified, then include default=1. That is, with

parser.add_argument('--example', nargs='?', const=1, type=int, default=1)

then

% test.py

The -X options are non-standard and subject to change without notice.

I hope this will help you understand Xms, Xmx as well as many other things that matters the most. :)

The other answers cover how to do std dev in python sufficiently, but no one explains how to do the bizarre traversal you've described.

I'm going to assume A-Z is the entire population. If not see Ome's answer on how to inference from a sample.

So to get the standard deviation/mean of the first digit of every list you would need something like this:

#standard deviation
numpy.std([A_rank[0], B_rank[0], C_rank[0], ..., Z_rank[0]])

#mean
numpy.mean([A_rank[0], B_rank[0], C_rank[0], ..., Z_rank[0]])

To shorten the code and generalize this to any nth digit use the following function I generated for you:

def getAllNthRanks(n):
    return [A_rank[n], B_rank[n], C_rank[n], D_rank[n], E_rank[n], F_rank[n], G_rank[n], H_rank[n], I_rank[n], J_rank[n], K_rank[n], L_rank[n], M_rank[n], N_rank[n], O_rank[n], P_rank[n], Q_rank[n], R_rank[n], S_rank[n], T_rank[n], U_rank[n], V_rank[n], W_rank[n], X_rank[n], Y_rank[n], Z_rank[n]] 

Now you can simply get the stdd and mean of all the nth places from A-Z like this:

#standard deviation
numpy.std(getAllNthRanks(n))

#mean
numpy.mean(getAllNthRanks(n))

To add to the other answers, here are the variable list from Python Documentation.

Have you tried the import text function.

If I understand right, you've made a commit to changed_branch and you want to copy that commit to other_branch? Easy:

git checkout other_branch
git cherry-pick changed_branch

Alternative way (but it's not python style. It's JS style)

{{ files and 'Update' or 'Continue' }}

Maybe it depends, but I thought NULL=NULL evaluates to NULL like most operations with NULL as an operand.

Following will disable all the input but will not able it to btn class and also added class to overwrite disable css.

$('#EditForm :input').not('.btn').attr("disabled", true).addClass('disabledClass');

css class

.disabledClass{
  background-color: rgb(235, 235, 228) !important;
}

These are 2 equivalent solutions:

(in the following code, you should substitute 'UTC' for zone and now() for timestamp)

1. timestamp AT TIME ZONE zone - SQL-standard-conforming
2. timezone(zone, timestamp) - arguably more readable

The function timezone(zone, timestamp) is equivalent to the SQL-conforming construct timestamp AT TIME ZONE zone.

Explanation:

• zone can be specified either as a text string (e.g., 'UTC') or as an interval (e.g., INTERVAL '-08:00') - here is a list of all available time zones
• timestamp can be any value of type timestamp
• now() returns a value of type timestamp (just what we need) with your database's default time zone attached (e.g. 2018-11-11T12:07:22.3+05:00).
• timezone('UTC', now()) turns our current time (of type timestamp with time zone) into the timezonless equivalent in UTC.
  E.g., SELECT timestamp with time zone '2020-03-16 15:00:00-05' AT TIME ZONE 'UTC' will return 2020-03-16T20:00:00Z.

Docs: timezone()

Just use the existing method.. .ToList();

   List<int> listArray = array.ToList();

This worked for me:

command prompt or gitbash into the node_modules folder in your project then execute:

npm uninstall *

Removed all of the local packages for that project.

Use something like this -

SELECT DISTINCT COL_NAME FROM myTable WHERE UPPER(COL_NAME) LIKE UPPER('%PriceOrder%')

or

SELECT DISTINCT COL_NAME FROM myTable WHERE LOWER(COL_NAME) LIKE LOWER('%PriceOrder%')

var newData = [1,2,3,4,5,6,7];
var chart = $('#chartjs').highcharts();
chart.series[0].setData(newData, true);

Explanation:
Variable newData contains value that want to update in chart. Variable chart is an object of a chart. setData is a method provided by highchart to update data.

Method setData contains two parameters, in first parameter we need to pass new value as array and second param is Boolean value. If true then chart updates itself and if false then we have to use redraw() method to update chart (i.e chart.redraw();)

You are right, that test "and"s the two operands. But the result is discarded, the only thing that stays, and thats the important part, are the flags. They are set and thats the reason why the test instruction is used (and exist).

JE jumps not when equal (it has the meaning when the instruction before was a comparison), what it really does, it jumps when the ZF flag is set. And as it is one of the flags that is set by test, this instruction sequence (test x,x; je...) has the meaning that it is jumped when x is 0.

For questions like this (and for more details) I can just recommend a book about x86 instruction, e.g. even when it is really big, the Intel documentation is very good and precise.

Base on @Jonik answer I have created fully functional extension to ArrayAdapter

Remove all files not belonging to a repositiory (e.g. for a clean-build after switching a branch):

 git status | xargs rm -rf

When I encountered this problem most recently I tried everything mentioned here but to no avail. After tearing my hair out I decided to try deleting my entire code base (yes, pretty desperate!) and then re-downloaded everything from my code repository. After doing this everything worked fine once more.

Seems an extreme solution but just thought I'd include it here as it hasn't been mentioned before in this thread.

(Note that the other time I have encountered this issue, is when the Global.asax was inheriting from a component which needed to be registered on the host machine. This was missing hence I got this same issue).

TL;DR; If all answers in this thread don't work for you, try deleting and then re-downloading your entire code base!

I think this is what you want:

>>> def twoDigitHex( number ):
...     return '%02x' % number
... 
>>> twoDigitHex( 2 )
'02'
>>> twoDigitHex( 255 )
'ff'

Yes. Use stat(). See the man page forstat(2).

stat() will fail if the file doesn't exist, otherwise most likely succeed. If it does exist, but you have no read access to the directory where it exists, it will also fail, but in that case any method will fail (how can you inspect the content of a directory you may not see according to access rights? Simply, you can't).

Oh, as someone else mentioned, you can also use access(). However I prefer stat(), as if the file exists it will immediately get me lots of useful information (when was it last updated, how big is it, owner and/or group that owns the file, access permissions, and so on).

I just got done doing this exact thing in a project. The HTML side looked a bit like this:

<a href="[fullsize]" class="gallerypic" title="">
  <img src="[thumbnail pic]" height="90" width="140" alt="[Gallery Photo]" class="pic" />
  <span class="zoom-icon">
      <img src="/images/misc/zoom.gif" width="32" height="32" alt="Zoom">
  </span>
</a>

Then using CSS:

a.gallerypic{
  width:140px;
  text-decoration:none;
  position:relative;
  display:block;
  border:1px solid #666;
  padding:3px;
  margin-right:5px;
  float:left;
}

a.gallerypic span.zoom-icon{
  visibility:hidden;
  position:absolute;
  left:40%;
  top:35%;
  filter:alpha(opacity=50);
  -moz-opacity:0.5;
  -khtml-opacity: 0.5;
  opacity: 0.5;
}

a.gallerypic:hover span.zoom-icon{
  visibility:visible;
}

I left a lot of the sample in there on the CSS so you can see how I decided to do the style. Note I lowered the opacity so you could see through the magnifying glass.

Hope this helps.

EDIT: To clarify for your example - you could ignore the visibility:hidden; and kill the :hover execution if you wanted, this was just the way I did it.

To Answer this in very short, this issue comes when your local has some information about the remote and someone changes something which makes remote and your changes unsync.

I was getting this issue because someone has deleted remote branch and again created with the same name.

For dealing with such issues, do a pull or fetch from remote.

git remote prune origin

or if you are using any GUI, do a fetch from remote.

The answer could be neither or both.

• neither: time.time() returns approximately the number of seconds elapsed since the Epoch. The result doesn't depend on timezone so it is neither UTC nor local time. Here's POSIX defintion for "Seconds Since the Epoch".

• both: time.time() doesn't require your system's clock to be synchronized so it reflects its value (though it has nothing to do with local timezone). Different computers may get different results at the same time. On the other hand if your computer time is synchronized then it is easy to get UTC time from the timestamp (if we ignore leap seconds):

  from datetime import datetime
  
  utc_dt = datetime.utcfromtimestamp(timestamp)
  

On how to get timestamps from UTC time in various Python versions, see How can I get a date converted to seconds since epoch according to UTC?

Well, I figured it out myself, right after posting, which is the most embarassing way. :)

It seems every member of a StackPanel will simply fill its minimum requested size.

In the DockPanel, I had docked things in the wrong order. If the TextBox or ListBox is the only docked item without an alignment, or if they are the last added, they WILL fill the remaining space as wanted.

I would love to see a more elegant method of handling this, but it will do.

List is the interface, not a class so it can't be instantiated. ArrayList is most likely what you're after:

ArrayList<Integer> list = new ArrayList<Integer>();

An interface in Java essentially defines a blueprint for the class - a class implementing an interface has to provide implementations of the methods the list defines. But the actual implementation is completely up to the implementing class, ArrayList in this case.

The JDK also provides LinkedList - an alternative implementation that again conforms to the list interface. It works very differently to the ArrayList underneath and as such it tends to be more efficient at adding / removing items half way through the list, but for the vast majority of use cases it's less efficient. And of course if you wanted to define your own implementation it's perfectly possible!

In short, you can't create a list because it's an interface containing no concrete code - that's the job of the classes that implement that list, of which ArrayList is the most used by far (and with good reason!)

It's also worth noting that in C# a List is a class, not an interface - that's IList. The same principle applies though, just with different names.

Arrow functions => best ES6 feature so far. They are a tremendously powerful addition to ES6, that I use constantly.

Wait, you can't use arrow function everywhere in your code, its not going to work in all cases like this where arrow functions are not usable. Without a doubt, the arrow function is a great addition it brings code simplicity.

But you can’t use an arrow function when a dynamic context is required: defining methods, create objects with constructors, get the target from this when handling events.

Arrow functions should NOT be used because:

1. They do not have this

   It uses “lexical scoping” to figure out what the value of “this” should be. In simple word lexical scoping it uses “this” from the inside the function’s body.

2. They do not have arguments

   Arrow functions don’t have an arguments object. But the same functionality can be achieved using rest parameters.

   let sum = (...args) => args.reduce((x, y) => x + y, 0) sum(3, 3, 1) // output - 7 `

3. They cannot be used with new

   Arrow functions can't be construtors because they do not have a prototype property.

When to use arrow function and when not:

1. Don't use to add function as a property in object literal because we can not access this.
2. Function expressions are best for object methods. Arrow functions are best for callbacks or methods like map, reduce, or forEach.
3. Use function declarations for functions you’d call by name (because they’re hoisted).
4. Use arrow functions for callbacks (because they tend to be terser).

You have already assigned a value to list.
So, you cannot use the list() when it’s a variable.
Restart the shell or IDE, by pressing Ctrl+F6 on your computer.
Hope this works too.

@Adam: I think in your code snippet you should track the start position for m.find() because string replacement may change the offset after the last character matched.

public static void replaceAll(StringBuilder sb, Pattern pattern, String replacement) {
    Matcher m = pattern.matcher(sb);
    int start = 0;
    while (m.find(start)) {
        sb.replace(m.start(), m.end(), replacement);
        start = m.start() + replacement.length();
    }
}

It's worth mentioning, that' exec's brother exist as well called execfile if you want to call a python file. That is sometimes good if you are working in a third party package which have terrible IDE's included and you want to code outside of their package.

Example:

execfile('/path/to/source.py)'

or:

exec(open("/path/to/source.py").read())

Here's something I found:

:pingtheserver
ping %input% | find "Reply" > nul
if not errorlevel 1 (
    echo server is online, up and running.
) else (
    echo host has been taken down wait 3 seconds to refresh
    ping 1.1.1.1 -n 1 -w 3000 >NUL
    goto :pingtheserver
) 

Note that ping 1.1.1.1 -n -w 1000 >NUL will wait 1 second but only works when connected to a network

I use final all the time on parameters.

Does it add that much? Not really.

Would I turn it off? No.

The reason: I found 3 bugs where people had written sloppy code and failed to set a member variable in accessors. All bugs proved difficult to find.

I'd like to see this made the default in a future version of Java. The pass by value/reference thing trips up an awful lot of junior programmers.

One more thing.. my methods tend to have a low number of parameters so the extra text on a method declaration isn't an issue.

UPDATE: Added a more detailed description of the formset errors.

Form.errors combines all field and non_field_errors. Therefore you can simplify the html to this:

template

    {% load form_tags %}

    {% if form.errors %}
    <div class="alert alert-danger alert-dismissible col-12 mx-1" role="alert">
        <div id="form_errors">
            {% for key, value in form.errors.items %}
                <span class="fieldWrapper">
                    {{ key }}:{{ value }}
                </span>
            {% endfor %}
        </div>
        <button type="button" class="close" data-dismiss="alert" aria-label="Close">
            <span aria-hidden="true">&times;</span>
        </button>
    </div>
    {% endif %}


If you want to generalise it you can create a list_errors.html which you include in every form template. It handles form and formset errors:

    {% if form.errors %}
    <div class="alert alert-danger alert-dismissible col-12 mx-1" role="alert">
        <div id="form_errors">

            {% for key, value in form.errors.items %}
                <span class="fieldWrapper">
                    {{ key }}:{{ value }}
                </span>
            {% endfor %}
        </div>
        <button type="button" class="close" data-dismiss="alert" aria-label="Close">
            <span aria-hidden="true">&times;</span>
        </button>
    </div>
    {% elif formset.total_error_count %}
    <div class="alert alert-danger alert-dismissible col-12 mx-1" role="alert">
        <div id="form_errors">
            {% if formset.non_form_errors %}
                {{ formset.non_form_errors }}
            {% endif %}
            {% for form in formset.forms %}
                {% if form.errors %}
                    Form number {{ forloop.counter }}:
                    <ul class="errorlist">
                    {% for key, error in form.errors.items %}

Here's the other one, particularly useful to convert the multiple columns to string instead of just single column:

In [76]: import numpy as np
In [77]: import pandas as pd
In [78]: df = pd.DataFrame({
    ...:     'A': [20, 30.0, np.nan],
    ...:     'B': ["a45a", "a3", "b1"],
    ...:     'C': [10, 5, np.nan]})
    ...: 

In [79]: df.dtypes ## Current datatype
Out[79]: 
A    float64
B     object
C    float64
dtype: object

## Multiple columns string conversion
In [80]: df[["A", "C"]] = df[["A", "C"]].astype(str) 

In [81]: df.dtypes ## Updated datatype after string conversion
Out[81]: 
A    object
B    object
C    object
dtype: object

first i had to click a little arrow button that opens a menu containing "Run Configurations",

then in the following window, i had to click "C/C++ Application", followed by a textless button with a green + on it

then i had to press the "Apply" and "Run" button

and then eclipse could run/debug the program. :)

The assert computer statement is analogous to the statement make sure in English.

As of VisualStudio 2015, if you keep all your code in one solution, you can share code by adding a shared project. Then add a reference to this shared project for each project you want to use the code in, as well as the proper using directives.

A simple question should be followed by a short, simple and clear answer.

• When we are getting a value of the property it fires its get{} part.

• When we are setting a value to the property it fires its set{} part.

PS. When setting a value to the property, SWIFT automatically creates a constant named "newValue" = a value we are setting. After a constant "newValue" becomes accessible in the property's set{} part.

Example:

var A:Int = 0
var B:Int = 0

var C:Int {
get {return 1}
set {print("Recived new value", newValue, " and stored into 'B' ")
     B = newValue
     }
}

//When we are getting a value of C it fires get{} part of C property
A = C 
A            //Now A = 1

//When we are setting a value to C it fires set{} part of C property
C = 2
B            //Now B = 2

I know this question is super old, but I want to offer 2 options that are more efficient:

1st off, the extension method posted by Paul Walls is good but can be made more efficient by using the StringBuilder class, which is like the string data type but made especially for situations where you will be changing string values more than once. Here is a version I made of the extension method using StringBuilder:

public static string ReplaceChars(this string s, char[] separators, char newVal)
{
    StringBuilder sb = new StringBuilder(s);
    foreach (var c in separators) { sb.Replace(c, newVal); }
    return sb.ToString();
}

I ran this operation 100,000 times and using StringBuilder took 73ms compared to 81ms using string. So the difference is typically negligible, unless you're running many operations or using a huge string.

Secondly, here is a 1 liner loop you can use:

foreach (char c in separators) { s = s.Replace(c, '\n'); }

I personally think this is the best option. It is highly efficient and doesn't require writing an extension method. In my testing this ran the 100k iterations in only 63ms, making it the most efficient. Here is an example in context:

string s = "this;is,\ra\t\n\n\ntest";
char[] separators = new char[] { ' ', ';', ',', '\r', '\t', '\n' };
foreach (char c in separators) { s = s.Replace(c, '\n'); }

Credit to Paul Walls for the first 2 lines in this example.

Specifically for boolean is*() getters:

I've spend a lot of time on why neither below

  @JsonAutoDetect(fieldVisibility = Visibility.ANY, getterVisibility = Visibility.NONE, setterVisibility = Visibility.NONE)

nor this

  setVisibility(PropertyAccessor.SETTER, JsonAutoDetect.Visibility.NONE);
  setVisibility(PropertyAccessor.GETTER, JsonAutoDetect.Visibility.NONE);
  setVisibility(PropertyAccessor.FIELD, JsonAutoDetect.Visibility.ANY);

worked for my Boolean Getter/Setter.

Solution is simple:

  @JsonAutoDetect(isGetterVisibility = Visibility.NONE, ...          
  setVisibility(PropertyAccessor.IS_GETTER, JsonAutoDetect.Visibility.NONE);

UPDATE: spring-boot allowed configure it:

jackson:
  visibility.field: any
  visibility.getter: none
  visibility.setter: none
  visibility.is-getter: none

Even though you want to just 1.5 compiler project, you can achieve it by changing compiler settings in Eclipse instead of removing 1.6 JRE and add 1.5 JRE.

GOTO -->JAVA--Compiler---> and change compiler level to `1.5` instead of `1.6`

As davidfmatheson suggested,

Just be careful, especially if you're setting this up for a team of people to work on. If anyone uses anything that is new or changed in 1.6, it will compile, but not run in an environment with JRE 1.5.

What does the if __name__ == "__main__": do?

To outline the basics:

• The global variable, __name__, in the module that is the entry point to your program, is '__main__'. Otherwise, it's the name you import the module by.

• So, code under the if block will only run if the module is the entry point to your program.

• It allows the code in the module to be importable by other modules, without executing the code block beneath on import.

Why do we need this?

Developing and Testing Your Code

Say you're writing a Python script designed to be used as a module:

def do_important():
    """This function does something very important"""

You could test the module by adding this call of the function to the bottom:

do_important()

and running it (on a command prompt) with something like:

~$ python important.py

The Problem

However, if you want to import the module to another script:

import important

On import, the do_important function would be called, so you'd probably comment out your function call, do_important(), at the bottom.

# do_important() # I must remember to uncomment to execute this!

And then you'll have to remember whether or not you've commented out your test function call. And this extra complexity would mean you're likely to forget, making your development process more troublesome.

A Better Way

The __name__ variable points to the namespace wherever the Python interpreter happens to be at the moment.

Inside an imported module, it's the name of that module.

But inside the primary module (or an interactive Python session, i.e. the interpreter's Read, Eval, Print Loop, or REPL) you are running everything from its "__main__".

So if you check before executing:

if __name__ == "__main__":
    do_important()

With the above, your code will only execute when you're running it as the primary module (or intentionally call it from another script).

An Even Better Way

There's a Pythonic way to improve on this, though.

What if we want to run this business process from outside the module?

If we put the code we want to exercise as we develop and test in a function like this and then do our check for '__main__' immediately after:

def main():
    """business logic for when running this module as the primary one!"""
    setup()
    foo = do_important()
    bar = do_even_more_important(foo)
    for baz in bar:
        do_super_important(baz)
    teardown()

# Here's our payoff idiom!
if __name__ == '__main__':
    main()

We now have a final function for the end of our module that will run if we run the module as the primary module.

It will allow the module and its functions and classes to be imported into other scripts without running the main function, and will also allow the module (and its functions and classes) to be called when running from a different '__main__' module, i.e.

import important
important.main()

This idiom can also be found in the Python documentation in an explanation of the __main__ module. That text states:

This module represents the (otherwise anonymous) scope in which the interpreter’s main program executes — commands read either from standard input, from a script file, or from an interactive prompt. It is this environment in which the idiomatic “conditional script” stanza causes a script to run:

if __name__ == '__main__':
    main()

You probably have allProviders typed as object[] as well. And property country does not exist on object. If you don't care about typing, you can declare both allProviders and countryProviders as Array<any>:

let countryProviders: Array<any>;
let allProviders: Array<any>;

If you do want static type checking. You can create an interface for the structure and use it:

interface Provider {
    region: string,
    country: string,
    locale: string,
    company: string
}

let countryProviders: Array<Provider>;
let allProviders: Array<Provider>;

This line will retrieve the whole HTML code of the frame. By using other methods instead of innerHTML you can traverse DOM of the inner document.

document.getElementById('iframe').contentWindow.document.body.innerHTML

Thing to remember is that this will work only if the frame source is on the same domain. If it is from a different domain, cross-site-scripting (XSS) protection will kick in.

This error can also show up if there are parts in your string that json.loads() does not recognize. An in this example string, an error will be raised at character 27 (char 27).

string = """[{"Item1": "One", "Item2": False}, {"Item3": "Three"}]"""

My solution to this would be to use the string.replace() to convert these items to a string:

import json

string = """[{"Item1": "One", "Item2": False}, {"Item3": "Three"}]"""

string = string.replace("False", '"False"')

dict_list = json.loads(string)

There are multiple classes that are grouped together as "numeric" classes, the 2 most common of which are double (for double precision floating point numbers) and integer. R will automatically convert between the numeric classes when needed, so for the most part it does not matter to the casual user whether the number 3 is currently stored as an integer or as a double. Most math is done using double precision, so that is often the default storage.

Sometimes you may want to specifically store a vector as integers if you know that they will never be converted to doubles (used as ID values or indexing) since integers require less storage space. But if they are going to be used in any math that will convert them to double, then it will probably be quickest to just store them as doubles to begin with.

use the following command to know the pid of the node already running.

curl -XGET 'http://localhost:9200/_nodes/process'

It took me an hour to find out the way to kill the node and could finally do it after using this command in the terminal window.

You can use the old <xmp> tag. I don't know about browser support, but it should still work.

<HTML>

your code/tables

<xmp>
    <catalog>
        <cd>
            <title>Empire Burlesque</title>
            <artist>Bob Dylan</artist>
            <country>USA</country>
            <country>Columbia</country>
            <price>10.90</price>
            <year>1985</year>
        </cd>
    </catalog>
</xmp>

Output:

your code/tables
<catalog>
    <cd>
        <title>Empire Burlesque</title>
        <artist>Bob Dylan</artist>
        <country>USA</country>
        <country>Columbia</country>
        <price>10.90</price>
        <year>1985</year>
    </cd>

This function will tell you if your string contains ONLY the characters 0123456789.

private bool IsInt(string sVal)
{
    foreach (char c in sVal)
    {
         int iN = (int)c;
         if ((iN > 57) || (iN < 48))
            return false;
    }
    return true;
}

This is different from int.TryParse() which will tell you if your string COULD BE an integer.
eg. " 123\r\n" will return TRUE from int.TryParse() but FALSE from the above function.

...Just depends on the question you need to answer.

Try this:

String[] trimmedArray = new String[array.length];
for (int i = 0; i < array.length; i++)
    trimmedArray[i] = array[i].trim();

Now trimmedArray contains the same strings as array, but without leading and trailing whitespace. Alternatively, you could write this for modifying the strings in-place in the same array:

for (int i = 0; i < array.length; i++)
    array[i] = array[i].trim();

If you want to avoid blocking, which is only necessary for very large loops, then wrap the contents of your loop in a function called like this: process.nextTick(function(){<contents of loop>}), which will defer execution until the next tick, giving an opportunity for pending calls from other asynchronous functions to be processed.

In the original example, why not use the select() method in your database query?

$name = DB::table('users')->where('name', 'John')->select("id");

This will be faster than using a PHP framework, for it'll utilize the SQL query to do the row selection for you. For ordinary collections, I don't believe this applies, but since you're using a database...

What is the difference between Relative path and absolute path?

One has to be calculated with respect to another URI. The other does not.

Is there any performance issues occures for using these paths?

Nothing significant.

We will get any secure for the sites ?

No

Is there any way to converting absolute path to relative

In really simplified terms: Working from left to right, try to match the scheme, hostname, then path segments with the URI you are trying to be relative to. Stop when you have a match.

size_t is the size of a pointer.

So in 32 bits or the common ILP32 (integer, long, pointer) model size_t is 32 bits. and in 64 bits or the common LP64 (long, pointer) model size_t is 64 bits (integers are still 32 bits).

There are other models but these are the ones that g++ use (at least by default)

I have solve this problem by configuring the build path. Here are the steps that I followed: In eclipse.

1. create a folder and save the logj4 file in it.
2. Write click in the folder created and go to Build path.
3. Click on Add folder
4. Choose the folder created.
5. Click ok and Apply and close.

Now you should be able to run

Circular imports can be confusing because import does two things:

1. it executes imported module code
2. adds imported module to importing module global symbol table

The former is done only once, while the latter at each import statement. Circular import creates situation when importing module uses imported one with partially executed code. In consequence it will not see objects created after import statement. Below code sample demonstrates it.

Circular imports are not the ultimate evil to be avoided at all cost. In some frameworks like Flask they are quite natural and tweaking your code to eliminate them does not make the code better.

main.py

print 'import b'
import b
print 'a in globals() {}'.format('a' in globals())
print 'import a'
import a
print 'a in globals() {}'.format('a' in globals())
if __name__ == '__main__':
    print 'imports done'
    print 'b has y {}, a is b.a {}'.format(hasattr(b, 'y'), a is b.a)

b.by

print "b in, __name__ = {}".format(__name__)
x = 3
print 'b imports a'
import a
y = 5
print "b out"

a.py

print 'a in, __name__ = {}'.format(__name__)
print 'a imports b'
import b
print 'b has x {}'.format(hasattr(b, 'x'))
print 'b has y {}'.format(hasattr(b, 'y'))
print "a out"

python main.py output with comments

import b
b in, __name__ = b    # b code execution started
b imports a
a in, __name__ = a    # a code execution started
a imports b           # b code execution is already in progress

I like Zakaria's answer, but if you're in a project where your team doesn't want to use that approach, and you're stuck trying to construct something with a String, integer, float, or primative type from a property file into the constructor, then you can use Spring's @Value annotation on the parameter in the constructor.

For example, I had an issue where I was trying to pull a string property into my constructor for a class annotated with @Service. My approach works for @Service, but I think this approach should work with any spring java class, if it has an annotation (such as @Service, @Component, etc.) which indicate that Spring will be the one constructing instances of the class.

Let's say in some yaml file (or whatever configuration you're using), you have something like this:

some:
    custom:
        envProperty: "property-for-dev-environment"

and you've got a constructor:

@Service // I think this should work for @Component, or any annotation saying Spring is the one calling the constructor.
class MyClass {
...
    MyClass(String property){
    ...
    }
...
}

This won't run as Spring won't be able to find the string envProperty. So, this is one way you can get that value:

class MyDynamoTable
import org.springframework.beans.factory.annotation.Value;
...
    MyDynamoTable(@Value("${some.custom.envProperty}) String property){
    ...
    }
...

In the above constructor, Spring will call the class and know to use the String "property-for-dev-environment" pulled from my yaml configuration when calling it.

NOTE: this I believe @Value annotation is for strings, intergers, and I believe primative types. If you're trying to pass custom classes (beans), then approaches in answers defined above work.

I work through these two ways without any problem:

<pre>
<code>
 ... java code, even including annotations
</code>
</pre>

and

<pre class="code">
 ... java code, even including annotations
</pre>

Of course the latter is more simplest and observe the class="code" part

Supervised learning:

A supervised learning algorithm analyzes the training data and produces an inferred function, which can be used for mapping new examples.

1. We provide training data and we know correct output for a certain input
2. We know relation between input and output

Categories of problem:

Regression: Predict results within a continuous output => map input variables to some continuous function.

Example:

Given a picture of a person, predict his age

Classification: Predict results in a discrete output => map input variables into discrete categories

Example:

Is this tumer cancerous?

Unsupervised learning:

Unsupervised learning learns from test data that has not been labeled, classified or categorized. Unsupervised learning identifies commonalities in the data and reacts based on the presence or absence of such commonalities in each new piece of data.

1. We can derive this structure by clustering the data based on relationships among the variables in the data.

2. There is no feedback based on the prediction results.

Categories of problem:

Clustering: is the task of grouping a set of objects in such a way that objects in the same group (called a cluster) are more similar (in some sense) to each other than to those in other groups (clusters)

Example:

Take a collection of 1,000,000 different genes, and find a way to automatically group these genes into groups that are somehow similar or related by different variables, such as lifespan, location, roles, and so on.

Popular use cases are listed here.

I can confirm that the answer it to upgrade Xcode to 6.1. If you are using Xcode 6.0.x you will not be able to select a device running 8.1. Your deployment targets and OS version should have nothing to do with this.

If your OS version is greater than 10.9.4 I would recommend this. First, un-attaching all devices. Download Xcode 6.1. After opening the new version of Xcode attach your device. You should be good to go.

Another good thing would be to look at the release notes. It's and easy read and gives you a general idea of what still needs to be fixed.

A reproducible example:

the_plot <- function()
{
  x <- seq(0, 1, length.out = 100)
  y <- pbeta(x, 1, 10)
  plot(
    x,
    y,
    xlab = "False Positive Rate",
    ylab = "Average true positive rate",
    type = "l"
  )
}

James's suggestion of using pointsize, in combination with the various cex parameters, can produce reasonable results.

png(
  "test.png",
  width     = 3.25,
  height    = 3.25,
  units     = "in",
  res       = 1200,
  pointsize = 4
)
par(
  mar      = c(5, 5, 2, 2),
  xaxs     = "i",
  yaxs     = "i",
  cex.axis = 2,
  cex.lab  = 2
)
the_plot()
dev.off()

Of course the better solution is to abandon this fiddling with base graphics and use a system that will handle the resolution scaling for you. For example,

library(ggplot2)

ggplot_alternative <- function()
{
  the_data <- data.frame(
    x <- seq(0, 1, length.out = 100),
    y = pbeta(x, 1, 10)
  )

ggplot(the_data, aes(x, y)) +
    geom_line() +
    xlab("False Positive Rate") +
    ylab("Average true positive rate") +
    coord_cartesian(0:1, 0:1)
}

ggsave(
  "ggtest.png",
  ggplot_alternative(),
  width = 3.25,
  height = 3.25,
  dpi = 1200
)

You want to execute code where the id is not (1 or 2 or 3), but the OR operator does not distribute over id. The only way to say what you want is to say

the id is not 1, and the id is not 2, and the id is not 3.

which translates to

if (id !== 1 && id !== 2 && id !== 3)

or alternatively for something more pythonesque:

if (!(id in [,1,2,3]))

You can do this by using CSS: JSFiddle

HTML:

<select>
    <option>Text 1</option>
    <option>Text 2</option>
    <option>Text 3</option>
</select>

CSS:

select option:first-child { color:red; }

Or if you absolutely need to use JavaScript (not adviced for this): JSFiddle

JavaScript:

$(function() {
    $("select option:first-child").addClass("highlight");
});

CSS:

.highlight { color:red; }

• A closure is a subprogram and the referencing environment where it was defined

– The referencing environment is needed if the subprogram can be called from any arbitrary place in the program

– A static-scoped language that does not permit nested subprograms doesn’t need closures

– Closures are only needed if a subprogram can access variables in nesting scopes and it can be called from anywhere

– To support closures, an implementation may need to provide unlimited extent to some variables (because a subprogram may access a nonlocal variable that is normally no longer alive)

Example

function makeAdder(x) {
return function(y) {return x + y;}
}
var add10 = makeAdder(10);
var add5 = makeAdder(5);
document.write("add 10 to 20: " + add10(20) +
"<br />");
document.write("add 5 to 20: " + add5(20) +
"<br />");

With GNU Parallel you can do:

cat file | parallel 'foo {}; foo2 {}; foo3 {}'

This will run one job on each cpu core. To run 50 do:

cat file | parallel -j 50 'foo {}; foo2 {}; foo3 {}'

git reset --hard origin/master

OR If you are on some other branch:

git reset --hard origin/<branch_name>

In my case I had a terrible mistake. I put @Service up to the service interface.

To fix it, I put @Service on the implementation of service file and it worked for me.

Try setTitle by itself, like this:

setTitle("Hello StackOverflow");

You can use map method from this array library to achieve exactly what you want as easily as:

Arr::map($test_array, function($a, $b) { return "$a loves $b"; });

also it preserves keys and returns new array, not to mention few different modes to fit your needs.

I think new is evil, not because if you forget to use it by mistake it might cause problems but because it screws up the inheritance chain, making the language tougher to understand.

JavaScript is prototype-based object-oriented. Hence every object MUST be created from another object like so var newObj=Object.create(oldObj). Here oldObj is called the prototype of newObj (hence "prototype-based"). This implies that if a property is not found in newObj then it will be searched in oldObj. newObj by default will thus be an empty object but due to its prototype chain it appears to have all the values of oldObj.

On the other hand if you do var newObj=new oldObj(), the prototype of newObj is oldObj.prototype, which is unnecessarily difficult to understand.

The trick is to use

Object.create=function(proto){
  var F = function(){};
  F.prototype = proto;
  var instance = new F();
  return instance;
};

It is inside this function and only here that new should be used. After this simply use the Object.create() method. The method resolves the prototype problem.

Using the fontawesome-all.css file: Changing the "Brands" font-family from "Font Awesome 5 Free" to "Font Awesome 5 Brands" fixed the issues I was having.

I can't take all of the credit - I fixed my own local issue right before looking at the CDN version: https://use.fontawesome.com/releases/v5.0.6/css/all.css

They've got the issue sorted out on the CDN as well.

 @font-face {_x000D_
    font-family: 'Font Awesome 5 Brands';_x000D_
    font-style: normal;_x000D_

    src: url("../webfonts/fa-brands-400.eot");_x000D_
    src: url("../webfonts/fa-brands-400.eot?#iefix") format("embedded-opentype"), url("../webfonts/fa-brands-400.woff2") format("woff2"), url("../webfonts/fa-brands-400.woff") format("woff"), url("../webfonts/fa-brands-400.ttf") format("truetype"), url("../webfonts/fa-brands-400.svg#fontawesome") format("svg"); }_x000D_

For XCUITest to stop the test finishing before the async request completes use this (maybe reduce the 100 timeout):

func test_api() {
    let url = URL(string: "https://jsonplaceholder.typicode.com/posts/42")!
    let exp = expectation(description: "Waiting for data")
    let task = URLSession.shared.dataTask(with: url) {(data, response, error) in
        guard let data = data else { return }
        print(String(data: data, encoding: .utf8)!)
        exp.fulfill()
    }
    task.resume()
    XCTWaiter.wait(for: [exp], timeout: 100)
}

To delete all derived data and the module cache in /var/folders use this little ruby script.

derivedDataFolder = Dir.glob(Dir.home + "/Library/Developer/Xcode/DerivedData/*")
moduleCache = Dir.glob("/var/folders/**/com.apple.DeveloperTools*")
FileUtils.rm_rf derivedDataFolder + moduleCache

This just solved a fatal error: malformed or corrupted AST file: 'Unable to load module "/var/folders/ error for me.

You can use apache's commons-text library (instead of commons-lang):

Example code:

org.apache.commons.text.StringEscapeUtils.escapeJava(escapedString);

Dependency:

compile 'org.apache.commons:commons-text:1.8'

OR

<dependency>
   <groupId>org.apache.commons</groupId>
   <artifactId>commons-text</artifactId>
   <version>1.8</version>
</dependency>

in my case adding <clear /> just after <connectionStrings> worked like charm

My program does exactly what you are after, no prompts or anything, please see the following code.

This code will create all of the necessary directories if they don't already exist:

Directory.CreateDirectory(C:\dir\dira\dirb);  // This code will create all of these directories  

This code will download the given file to the given directory (after it has been created by the previous snippet:

private void install()
    {
        WebClient webClient = new WebClient();                                                          // Creates a webclient
        webClient.DownloadFileCompleted += new AsyncCompletedEventHandler(Completed);                   // Uses the Event Handler to check whether the download is complete
        webClient.DownloadProgressChanged += new DownloadProgressChangedEventHandler(ProgressChanged);  // Uses the Event Handler to check for progress made
        webClient.DownloadFileAsync(new Uri("http://www.com/newfile.zip"), @"C\newfile.zip");           // Defines the URL and destination directory for the downloaded file
    }

So using these two pieces of code you can create all of the directories and then tell the downloader (that doesn't prompt you to download the file to that location.
