Programs & Examples On #Union all

Both UNION and UNION ALL concatenate the result of two different SQLs. They differ in the way they handle duplicates.

• UNION performs a DISTINCT on the result set, eliminating any duplicate rows.

• UNION ALL does not remove duplicates, and it therefore faster than UNION.

Note: While using this commands all selected columns need to be of the same data type.

Example: If we have two tables, 1) Employee and 2) Customer

1. Employee table data:

2. Customer table data:

3. UNION Example (It removes all duplicate records):

4. UNION ALL Example (It just concatenate records, not eliminate duplicates, so it is faster than UNION):

Consider these tables (Standard SQL code, runs on SQL Server 2008):

WITH A 
     AS 
     (
      SELECT * 
        FROM (
              VALUES (1), 
                     (2), 
                     (3), 
                     (4), 
                     (5), 
                     (6) 
             ) AS T (col)
     ),
     B 
     AS 
     (
      SELECT * 
        FROM (
              VALUES (9), 
                     (8), 
                     (7), 
                     (6), 
                     (5), 
                     (4) 
             ) AS T (col)
     ), ...

The desired effect is this to sort table A by col ascending, sort table B by col descending then unioning the two, removing duplicates, retaining order before the union and leaving table A results on the "top" with table B on the "bottom" e.g. (pesudo code)

(
 SELECT *
   FROM A
  ORDER 
     BY col
)
UNION
(
 SELECT *
   FROM B
  ORDER 
     BY col DESC
);

Of course, this won't work in SQL because there can only be one ORDER BY clause and it can only be applied to the top level table expression (or whatever the output of a SELECT query is known as; I call it the "resultset").

The first thing to address is the intersection between the two tables, in this case the values 4, 5 and 6. How the intersection should be sorted needs to be specified in SQL code, therefore it is desirable that the designer specifies this too! (i.e. the person asking the question, in this case).

The implication in this case would seem to be that the intersection ("duplicates") should be sorted within the results for table A. Therefore, the sorted resultset should look like this:

      VALUES (1), -- A including intersection, ascending
             (2), -- A including intersection, ascending
             (3), -- A including intersection, ascending
             (4), -- A including intersection, ascending
             (5), -- A including intersection, ascending
             (6), -- A including intersection, ascending
             (9), -- B only, descending 
             (8), -- B only, descending  
             (7), -- B only, descending 

Note in SQL "top" and "bottom" has no inferent meaning and a table (other than a resultset) has no inherent ordering. Also (to cut a long story short) consider that UNION removes duplicate rows by implication and must be applied before ORDER BY. The conclusion has to be that each table's sort order must be explicitly defined by exposing a sort order column(s) before being unioned. For this we can use the ROW_NUMBER() windowed function e.g.

     ...
     A_ranked
     AS
     (
      SELECT col, 
             ROW_NUMBER() OVER (ORDER BY col) AS sort_order_1
        FROM A                      -- include the intersection
     ),
     B_ranked
     AS
     (
      SELECT *, 
             ROW_NUMBER() OVER (ORDER BY col DESC) AS sort_order_1
        FROM B
       WHERE NOT EXISTS (           -- exclude the intersection
                         SELECT * 
                           FROM A
                          WHERE A.col = B.col 
                        )
     )
SELECT *, 1 AS sort_order_0 
  FROM A_ranked
UNION
SELECT *, 2 AS sort_order_0 
  FROM B_ranked
ORDER BY sort_order_0, sort_order_1;

You can code the handler setup like this:

<area id="nose" shape="rect" coords="280,240,330,275" onmouseover="zoom.call(this)"/>

Then this in your handler will refer to the element. Now, I'll offer the caveat that I'm not 100% sure what happens when you've got a handler in an <area> tag, largely because I haven't seen an <area> tag in like a decade or so. I think it should give you the image tag, but that could be wrong.

edit — yes, it's wrong - you get the <area> tag, not the <img>. So you'll have to get that element's parent (the map), and then find the image that's using it (that is, the <img> whose "usemap" attribute refers to the map's name).

edit again — except it doesn't matter because you want the area's "id" durr. Sorry for not reading correctly.

You can use a trick, by creating a <a>-element, then setting the string to the href of that <a>-element and then you have a Location object you can get the hostname from.

You could either add a method to the String prototype:

String.prototype.toLocation = function() {
    var a = document.createElement('a');
    a.href = this;
    return a;
};

and use it like this:
"http://www.abc.com/search".toLocation().hostname

or make it a function:

function toLocation(url) {
    var a = document.createElement('a');
    a.href = url;
    return a;
};

and use it like this:
toLocation("http://www.abc.com/search").hostname

both of these will output: "www.abc.com"

If you also need the protocol, you can do something like this:

var url = "http://www.abc.com/search".toLocation();
url.protocol + "//" + url.hostname

which will output: "http://www.abc.com"

Okay, I was blind:

e.which

will contain the ASCII code of the key.

See https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/which

This worked for me:

Check the current role you are logged into by using: SELECT CURRENT_USER, SESSION_USER;

Note: It must match with Owner of the schema.

Schema | Name | Type | Owner
--------+--------+-------+----------

If the owner is different, then give all the grants to the current user role from the admin role by :

GRANT 'ROLE_OWNER' to 'CURRENT ROLENAME';

Then try to execute the query, it will give the output as it has access to all the relations now.

Another way:

x=$'Some\nstring'
readarray -t y <<<"$x"

Or, if you don't have bash 4, the bash 3.2 equivalent:

IFS=$'\n' read -rd '' -a y <<<"$x"

You can also do it the way you were initially trying to use:

y=(${x//$'\n'/ })

This, however, will not function correctly if your string already contains spaces, such as 'line 1\nline 2'. To make it work, you need to restrict the word separator before parsing it:

IFS=$'\n' y=(${x//$'\n'/ })

...and then, since you are changing the separator, you don't need to convert the \n to space anymore, so you can simplify it to:

IFS=$'\n' y=($x)

This approach will function unless $x contains a matching globbing pattern (such as "*") - in which case it will be replaced by the matched file name(s). The read/readarray methods require newer bash versions, but work in all cases.

You can use also system table_types view

IF EXISTS (SELECT *
           FROM   [sys].[table_types]
           WHERE  user_type_id = Type_id(N'[dbo].[UdTableType]'))
  BEGIN
      PRINT 'EXISTS'
  END 

As hadley mentioned there are more effective ways of communicating your message than labels in stacked bar charts. In fact, stacked charts aren't very effective as the bars (each Category) doesn't share an axis so comparison is hard.

It's almost always better to use two graphs in these instances, sharing a common axis. In your example I'm assuming that you want to show overall total and then the proportions each Category contributed in a given year.

library(grid)
library(gridExtra)
library(plyr)

# create a new column with proportions
prop <- function(x) x/sum(x)
Data <- ddply(Data,"Year",transform,Share=prop(Frequency))

# create the component graphics
totals <- ggplot(Data,aes(Year,Frequency)) + geom_bar(fill="darkseagreen",stat="identity") + 
  xlab("") + labs(title = "Frequency totals in given Year")
proportion <- ggplot(Data, aes(x=Year,y=Share, group=Category, colour=Category)) 
+ geom_line() + scale_y_continuous(label=percent_format())+ theme(legend.position = "bottom") + 
  labs(title = "Proportion of total Frequency accounted by each Category in given Year")

# bring them together
grid.arrange(totals,proportion)

This will give you a 2 panel display like this:

If you want to add Frequency values a table is the best format.

You can check out libvideo. It's much more up-to-date than YoutubeExtractor, and is fast and clean to use.

If you have a bunch of chars and want to concat them into a string, why not do

System.out.println("" + char1 + char2 + char3); 

?

$app = Get-WmiObject -Class Win32_Product | Where-Object { 
    $_.Name -match "Software Name" 
}

$app.Uninstall()

Edit: Rob found another way to do it with the Filter parameter:

$app = Get-WmiObject -Class Win32_Product `
                     -Filter "Name = 'Software Name'"

Just add these lines in your build.gradle file

resolutionStrategy.force "com.android.support:support-media-compat:26.0.0-beta2"

resolutionStrategy.force "com.android.support:support-v4:26.0.0-beta2"

Use the collapse argument to paste:

paste(a,collapse=" ")
[1] "aa bb cc"

As jkl pointed out, checking the element's visibility or display is not enough. You do have to check its ancestors. Selenium does this when it verifies visibility on an element.

Check out the method Selenium.prototype.isVisible in the selenium-api.js file.

We use Quack to pull a specific module from another Git repository. We need to pull code without the whole code base of the provided repository - we need a very specific module / file from that huge repository and should be updated every time we run update.

So we achieved it in this way:

Create configuration

name: Project Name

modules:
  local/path:
    repository: https://github.com/<username>/<repo>.git
    path: repo/path
    branch: dev
  other/local/path/filename.txt:
    repository: https://github.com/<username>/<repo>.git
    hexsha: 9e3e9642cfea36f4ae216d27df100134920143b9
    path: repo/path/filename.txt

profiles:
  init:
    tasks: ['modules']

With the above configuration, it creates one directory from the provided GitHub repository as specified in first module configuration, and the other one is to pull and create a file from the given repository.

Other developers just need to run

$ quack

And it pulls the code from the above configurations.

A simple way to do it would be to just annotate the Quartz Jobs with @Component annotation, and then Spring will do all the DI magic for you, as it is now recognized as a Spring bean. I had to do something similar for an AspectJ aspect - it was not a Spring bean until I annotated it with the Spring @Component stereotype.

I would strongly suggest using NDesk.Options (Documentation) and/or Mono.Options (same API, different namespace). An example from the documentation:

bool show_help = false;
List<string> names = new List<string> ();
int repeat = 1;

var p = new OptionSet () {
    { "n|name=", "the {NAME} of someone to greet.",
       v => names.Add (v) },
    { "r|repeat=", 
       "the number of {TIMES} to repeat the greeting.\n" + 
          "this must be an integer.",
        (int v) => repeat = v },
    { "v", "increase debug message verbosity",
       v => { if (v != null) ++verbosity; } },
    { "h|help",  "show this message and exit", 
       v => show_help = v != null },
};

List<string> extra;
try {
    extra = p.Parse (args);
}
catch (OptionException e) {
    Console.Write ("greet: ");
    Console.WriteLine (e.Message);
    Console.WriteLine ("Try `greet --help' for more information.");
    return;
}

After installing OpenSSL I was required to create a new environment variable:

• Name: OPENSSL_CONF
• Value: C:\Program Files\OpenSSL\openssl.cnf

In powershell:

$env:OPENSSL_CONF = "${env:ProgramFiles}\OpenSSL\openssl.cnf"

This value differs from previous installation versions (as seen in a previous edit of this post). Also, don't forget to add the openssl binary folder ${env:ProgramFiles}\OpenSSL to your Path.

Would suggest NOT using INSERT IGNORE as it ignores ALL errors (ie its a sloppy global ignore). Instead, since in your example tag is the unique key, use:

INSERT INTO table_tags (tag) VALUES ('tag_a'),('tab_b'),('tag_c') ON DUPLICATE KEY UPDATE tag=tag;

on duplicate key produces:

Query OK, 0 rows affected (0.07 sec)

Try running you asyntask from the UI thread. I faced this issue when I wasn't doing the same!

If your date column is a string of the format '2017-01-01' you can use pandas astype to convert it to datetime.

df['date'] = df['date'].astype('datetime64[ns]')

or use datetime64[D] if you want Day precision and not nanoseconds

print(type(df_launath['date'].iloc[0]))

yields

<class 'pandas._libs.tslib.Timestamp'> the same as when you use pandas.to_datetime

You can try it with other formats then '%Y-%m-%d' but at least this works.

This does what you want, and will work in nearly all cases:

>>> all(x in ['b', 'a', 'foo', 'bar'] for x in ['a', 'b'])
True

The expression 'a','b' in ['b', 'a', 'foo', 'bar'] doesn't work as expected because Python interprets it as a tuple:

>>> 'a', 'b'
('a', 'b')
>>> 'a', 5 + 2
('a', 7)
>>> 'a', 'x' in 'xerxes'
('a', True)

Other Options

There are other ways to execute this test, but they won't work for as many different kinds of inputs. As Kabie points out, you can solve this problem using sets...

>>> set(['a', 'b']).issubset(set(['a', 'b', 'foo', 'bar']))
True
>>> {'a', 'b'} <= {'a', 'b', 'foo', 'bar'}
True

...sometimes:

>>> {'a', ['b']} <= {'a', ['b'], 'foo', 'bar'}
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'list'

Sets can only be created with hashable elements. But the generator expression all(x in container for x in items) can handle almost any container type. The only requirement is that container be re-iterable (i.e. not a generator). items can be any iterable at all.

>>> container = [['b'], 'a', 'foo', 'bar']
>>> items = (i for i in ('a', ['b']))
>>> all(x in [['b'], 'a', 'foo', 'bar'] for x in items)
True

Speed Tests

In many cases, the subset test will be faster than all, but the difference isn't shocking -- except when the question is irrelevant because sets aren't an option. Converting lists to sets just for the purpose of a test like this won't always be worth the trouble. And converting generators to sets can sometimes be incredibly wasteful, slowing programs down by many orders of magnitude.

Here are a few benchmarks for illustration. The biggest difference comes when both container and items are relatively small. In that case, the subset approach is about an order of magnitude faster:

>>> smallset = set(range(10))
>>> smallsubset = set(range(5))
>>> %timeit smallset >= smallsubset
110 ns ± 0.702 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)
>>> %timeit all(x in smallset for x in smallsubset)
951 ns ± 11.5 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

This looks like a big difference. But as long as container is a set, all is still perfectly usable at vastly larger scales:

>>> bigset = set(range(100000))
>>> bigsubset = set(range(50000))
>>> %timeit bigset >= bigsubset
1.14 ms ± 13.9 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
>>> %timeit all(x in bigset for x in bigsubset)
5.96 ms ± 37 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

Using subset testing is still faster, but only by about 5x at this scale. The speed boost is due to Python's fast c-backed implementation of set, but the fundamental algorithm is the same in both cases.

If your items are already stored in a list for other reasons, then you'll have to convert them to a set before using the subset test approach. Then the speedup drops to about 2.5x:

>>> %timeit bigset >= set(bigsubseq)
2.1 ms ± 49.2 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

And if your container is a sequence, and needs to be converted first, then the speedup is even smaller:

>>> %timeit set(bigseq) >= set(bigsubseq)
4.36 ms ± 31.4 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

The only time we get disastrously slow results is when we leave container as a sequence:

>>> %timeit all(x in bigseq for x in bigsubseq)
184 ms ± 994 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)

And of course, we'll only do that if we must. If all the items in bigseq are hashable, then we'll do this instead:

>>> %timeit bigset = set(bigseq); all(x in bigset for x in bigsubseq)
7.24 ms ± 78 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

That's just 1.66x faster than the alternative (set(bigseq) >= set(bigsubseq), timed above at 4.36).

So subset testing is generally faster, but not by an incredible margin. On the other hand, let's look at when all is faster. What if items is ten-million values long, and is likely to have values that aren't in container?

>>> %timeit hugeiter = (x * 10 for bss in [bigsubseq] * 2000 for x in bss); set(bigset) >= set(hugeiter)
13.1 s ± 167 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
>>> %timeit hugeiter = (x * 10 for bss in [bigsubseq] * 2000 for x in bss); all(x in bigset for x in hugeiter)
2.33 ms ± 65.2 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

Converting the generator into a set turns out to be incredibly wasteful in this case. The set constructor has to consume the entire generator. But the short-circuiting behavior of all ensures that only a small portion of the generator needs to be consumed, so it's faster than a subset test by four orders of magnitude.

This is an extreme example, admittedly. But as it shows, you can't assume that one approach or the other will be faster in all cases.

The Upshot

Most of the time, converting container to a set is worth it, at least if all its elements are hashable. That's because in for sets is O(1), while in for sequences is O(n).

On the other hand, using subset testing is probably only worth it sometimes. Definitely do it if your test items are already stored in a set. Otherwise, all is only a little slower, and doesn't require any additional storage. It can also be used with large generators of items, and sometimes provides a massive speedup in that case.

As others have mentioned, Dart's is operator is the equivalent of Javascript's instanceof operator. However, I haven't found a direct analogue of the typeof operator in Dart.

Thankfully the dart:mirrors reflection API has recently been added to the SDK, and is now available for download in the latest Editor+SDK package. Here's a short demo:

import 'dart:mirrors'; 

getTypeName(dynamic obj) {
  return reflect(obj).type.reflectedType.toString();
}

void main() {
  var val = "\"Dart is dynamically typed (with optional type annotations.)\"";
  if (val is String) {
    print("The value is a String, but I needed "
        "to check with an explicit condition.");
  }
  var typeName = getTypeName(val);
  print("\nThe mirrored type of the value is $typeName.");
}

Please install http://asepsis.binaryage.com/ and then reboot your mac.

ASEPSIS redirect all .DS_Store on your mac to /usr/local/.dscage

After that, You could delete recursively all .DS_Store from your mac.

find ~ -name ".DS_Store" -delete
or
find <your path> -name ".DS_Store" -delete

You should repeat procedure after each Mac major update.

This is a lightweight solution I've come across -

function E() { // Check collision
    S = X - x;
    D = Y - y;
    F = w + W;
    return (S * S + D * D <= F * F)
}

The big and small variables are of two objects, (x coordinate, y coordinate, and w width)

From here.

I will suggest something totally different, we used it at work for many years ago on real computers and it worked perfect.

Boot both old and new machine on linux rescue Cd.

read the disk from one, and write it down to the other one, block by block, effectively copying the dist over the network.

You have to play around a little bit with the command line, but it worked so well that both machine complained about IP-conflict when they both booted :-) :-)

cat /dev/sda | ssh user@othermachine cat - > /dev/sda

Could not figure out what you want, but you need something like this ? :

?def a = { b -> b = 1 }
?bValue = a()
println b // prints 1

Now bValue contains the value of b which is a variable in the closure a. Now you can do anything with bValue Let me know if i have misunderstood your question

This should work.

int i = 1;
foreach (ListViewItem lvi in listView.Items) {
    ...
    if(++i == 50) break;
}

One way to do that is to set the cascade option on you "One" side of relationship:

class Employee {
   // 

   @OneToMany(cascade = {CascadeType.PERSIST})
   private Set<Vehicles> vehicles = new HashSet<Vehicles>();

   //
}

by this, when you call

Employee savedEmployee = employeeDao.persistOrMerge(newEmployee);

it will save the vehicles too.

This will be a simple command for this

nodemon --exec npm start

If you're using .NET 3.5 SP1+ the better way to do this is to take a look at the

System.DirectoryServices.AccountManagement namespace.

It has methods to find people and you can pretty much pass in any username format you want and then returns back most of the basic information you would need. If you need help on loading the more complex objects and properties check out the source code for http://umanage.codeplex.com its got it all.

use this filter:

what this query does is it only gives dns queries originated from your ip

UITableView has a property separatorInset. You can use that to set the insets of the table view separators to zero to let them span the full width of the screen.

[tableView setSeparatorInset:UIEdgeInsetsZero];

Note: If your app is also targeting other iOS versions, you should check for the availability of this property before calling it by doing something like this:

if ([tableView respondsToSelector:@selector(setSeparatorInset:)]) {
    [tableView setSeparatorInset:UIEdgeInsetsZero];
}

Using solve with a single parameter is a request to invert a matrix. The error message is telling you that your matrix is singular and cannot be inverted.

it is safe to delete the inetpub it is only a cache.

You should try using some jQuery plugin like ikSelect.

I tried to make it very customizable but easy to use.

Problem Cause

In mac os image rendering back end of matplotlib (what-is-a-backend to render using the API of Cocoa by default). There are Qt4Agg and GTKAgg and as a back-end is not the default. Set the back end of macosx that is differ compare with other windows or linux os.

Solution

• I assume you have installed the pip matplotlib, there is a directory in your root called ~/.matplotlib.
• Create a file ~/.matplotlib/matplotlibrc there and add the following code: backend: TkAgg

From this link you can try different diagrams.

You use the lpMultiByteStr [out] parameter by creating a new char array. You then pass this char array in to get it filled. You only need to initialize the length of the string + 1 so that you can have a null terminated string after the conversion.

Here are a couple of useful helper functions for you, they show the usage of all parameters.

#include <string>

std::string wstrtostr(const std::wstring &wstr)
{
    // Convert a Unicode string to an ASCII string
    std::string strTo;
    char *szTo = new char[wstr.length() + 1];
    szTo[wstr.size()] = '\0';
    WideCharToMultiByte(CP_ACP, 0, wstr.c_str(), -1, szTo, (int)wstr.length(), NULL, NULL);
    strTo = szTo;
    delete[] szTo;
    return strTo;
}

std::wstring strtowstr(const std::string &str)
{
    // Convert an ASCII string to a Unicode String
    std::wstring wstrTo;
    wchar_t *wszTo = new wchar_t[str.length() + 1];
    wszTo[str.size()] = L'\0';
    MultiByteToWideChar(CP_ACP, 0, str.c_str(), -1, wszTo, (int)str.length());
    wstrTo = wszTo;
    delete[] wszTo;
    return wstrTo;
}

--

Anytime in documentation when you see that it has a parameter which is a pointer to a type, and they tell you it is an out variable, you will want to create that type, and then pass in a pointer to it. The function will use that pointer to fill your variable.

So you can understand this better:

//pX is an out parameter, it fills your variable with 10.
void fillXWith10(int *pX)
{
  *pX = 10;
}

int main(int argc, char ** argv)
{
  int X;
  fillXWith10(&X);
  return 0;
}

2. If you are using Latest Ajax Control Toolkit (I am not sure about version 4.0 or 4.5) you need to use that Particular ToolkitScriptManager and not ScriptManager from default Ajax Extensions.

3. You can use only one ScriptManager or ToolKitScriptManager on page, If you have added it on Master Page you no need to add it again on Web Page.

4. The problem mentioned here may because of ContentPlaceHolder Please Check how many content place holders you have on your master page. Lets take an example if you have 2 content Placeholders "Head" and "ContentPlaceHolder1" on Master Page and ContentPlaceHolder1 is your Content Page.please check below code I added here my ScriptManager on Second Placeholder just below there is update panel.

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <asp:ContentPlaceHolder id="head" runat="server">
    </asp:ContentPlaceHolder>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:ContentPlaceHolder id="MainContent" runat="server">
        <asp:ScriptManager ID="ScriptManger1" runat="Server" />
          <asp:UpdatePanel ID="UpdatePanel1" runat="server">
    <ContentTemplate>
    </ContentTemplate>
</asp:UpdatePanel>
        </asp:ContentPlaceHolder>
    </div>
    </form>
</body>
</html> 

Most of us make mistake while designing web form when we choose masterpage by default on web page there are equal number of placeholders as of MasterPage.

<%@ Page Title="" Language="C#" MasterPageFile="~/Master Pages/Home.master" AutoEventWireup="true" CodeFile="frmCompanyLogin.aspx.cs" Inherits="Authentication_frmCompanyLogin" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" Runat="Server">
</asp:Content>

We no need to remove any PlaceHolder it is guiding structure but you must have to add the web form Contents in Same PlaceHolder where you added your ScriptManager(on Master Page) or add Script Manager in appropriate Placeholder or any place Holder which appears before the content in which Ajax Control is used.

Change this:

$(document).click( function () {

To this

$(document).on('click touchstart', function () {

Maybe this solution don't fit on your work and like described on the replies this is not the best solution to apply. Please, check another fixes from another users.

Here's a sed version:

sed -e '\|include "/configs/projectname.conf"|h; ${x;s/incl//;{g;t};a\' -e 'include "/configs/projectname.conf"' -e '}' file

If your string is in a variable:

string='include "/configs/projectname.conf"'
sed -e "\|$string|h; \${x;s|$string||;{g;t};a\\" -e "$string" -e "}" file

If you are starting out a react-native app and seeing this issue, then you have to follow all the instructions listed in firebase (when you setup iOS/android app) or the instructions @ React-native google auth android DEVELOPER_ERROR Code 10 question

Maybe not so perfect as above ones, but I guess this is what you were looking for.

data[1:1,3:3]    #works with positive integers
data[1:1, -3:-3] #does not work, gives the entire 1st row without the 3rd element
data[i:i,j:j]    #given that i and j are positive integers

Here indexing will work from 1, i.e,

data[1:1,1:1]    #means the top-leftmost element

This script searches in a folder and sub folders and rename files by removing their extension

    Get-ChildItem -Path "C:/" -Recurse -Filter *.wctc |

    Foreach-Object {

      rename-item $_.fullname -newname $_.basename

    }

I would like to mention a new method which uses the user defined literal s. This isn't new, but it will be more common because it was added in the C++14 Standard Library.

Largely superfluous in the general case:

string mystring = "your string here"s;

But it allows you to use auto, also with wide strings:

auto mystring = U"your UTF-32 string here"s;

And here is where it really shines:

string suffix;
cin >> suffix;
string mystring = "mystring"s + suffix;

I know this one is already too late. But we can fetch root URL by two methods

1st method

var path = require('path');
path.dirname(require.main.filename);

2nd method

var path = require('path');
path.dirname(process.mainModule.filename);

Reference Link:- https://gist.github.com/geekiam/e2e3e0325abd9023d3a3

For a DATE column you can use:

NULLS last:

ORDER BY IFNULL(`myDate`, '9999-12-31') ASC

Blanks last:

ORDER BY IF(`myDate` = '', '9999-12-31', `myDate`) ASC

To access field or method of an object use dot .:

user = User()
print user.fullName

If a name of the field will be defined at run time, use buildin getattr function:

field_name = "fullName"
print getattr(user, field_name) # prints content of user.fullName

As a newbie, I faced the same 'problem'.

In newbie terms : when you call plot(), the graph window gets the focus and you cannot enter further commands into R. That is when you conclude that you must close the graph window to return to R. However, some commands, like identify(), act on open/active graph windows. When identify() cannot find an open/active graph window, it gives this error message.

However, you can simply click on the R window without closing the graph window. Then you can type more commands at the R prompt, like identify() etc.

Solve it by placing the following include files and definition first:

#define WIN32_LEAN_AND_MEAN      // Exclude rarely-used stuff from Windows headers

#include <windows.h>

The best solution to this in my opinion is this:

1. Create a custom filter which can be in a common.module.js file for example - used through out your app:

   var app = angular.module('common.module', []);
   
   // html filter (render text as html)
   app.filter('html', ['$sce', function ($sce) { 
       return function (text) {
           return $sce.trustAsHtml(text);
       };    
   }])
   

2. Usage:

   <span ng-bind-html="yourDataValue | html"></span>
   

Now - I don't see why the directive ng-bind-html does not trustAsHtml as part of its function - seems a bit daft to me that it doesn't

Anyway - that's the way I do it - 67% of the time, it works ever time.

For those who are newbie like me, Open IIS, expand your server name, choose sites, click on your website. On new install, it is Default web site. Click it. On the right side you have Default document option. Double click it. You will see default.htm, default.asp, index.htm etc.. to the extreme right click add. Enter the full name of your file(including extension) that you want to set it as default. click ok. Open cmd prompt as admin and reset iis. Remove all files from c:\inetpub\wwwroot folder like iisstart.html, index.html etc.

Note: This will automatically create web.config file in your c:\inetpub\wwwroot folder. I didnt have any web.config files in my inetpub or wwwroot folders. This automatically created one for me.

Next time when you enter http(s)://servername, it opens the default page you set.

just use php composer.phar require

For example :

php composer.phar require doctrine/mongodb-odm-bundle 3.0

Also available with install.

https://getcomposer.org/doc/03-cli.md#require https://getcomposer.org/doc/03-cli.md#install

The correct value for the content attribute should include initial-scale instead:

<meta name="viewport" content="width=device-width, initial-scale=1">_x000D_
                                                   ^^^^^^^^^^^^^^^

In my case, I was inflating a PopupMenu at the very beginning of the activity i.e on onCreate()... I fixed it by putting it in a Handler

  new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                PopupMenu popuMenu=new PopupMenu(SplashScreen.this,binding.progressBar);
                popuMenu.inflate(R.menu.bottom_nav_menu);
                popuMenu.show();
            }
        },100);

Use the :checked selector to determine the checkbox's state:

$('input[type=checkbox]').click(function() {
    if($(this).is(':checked')) {
        ...
    } else {
        ...
    }
});

Just for clarification: setRequestProperty("User-Agent", "Mozilla ...") now works just fine and doesn't append java/xx at the end! At least with Java 1.6.30 and newer.

I listened on my machine with netcat(a port listener):

$ nc -l -p 8080

It simply listens on the port, so you see anything which gets requested, like raw http-headers.

And got the following http-headers without setRequestProperty:

GET /foobar HTTP/1.1
User-Agent: Java/1.6.0_30
Host: localhost:8080
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Connection: keep-alive

And WITH setRequestProperty:

GET /foobar HTTP/1.1
User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9.2.2) Gecko/20100316 Firefox/3.6.2
Host: localhost:8080
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Connection: keep-alive

As you can see the user agent was properly set.

Full example:

import java.io.IOException;
import java.net.URL;
import java.net.URLConnection;


public class TestUrlOpener {

    public static void main(String[] args) throws IOException {
        URL url = new URL("http://localhost:8080/foobar");
        URLConnection hc = url.openConnection();
        hc.setRequestProperty("User-Agent", "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9.2.2) Gecko/20100316 Firefox/3.6.2");

        System.out.println(hc.getContentType());
    }

}

Not Equal To

Before C came along and popularized !=, languages tended to use <> for not equal to.

At least, the various dialects of Basic did, and they predate C.

An even older and more unusual case is Fortran, which uses .NE., as in X .NE. Y.

Here are my working example

@RequestMapping(value = "/api/v1/files/upload", method =RequestMethod.POST)
public ResponseEntity<?> upload(@RequestParam("files") MultipartFile[] files) {
    LinkedMultiValueMap<String, Object> map = new LinkedMultiValueMap<>();
    List<String> tempFileNames = new ArrayList<>();
    String tempFileName;
    FileOutputStream fo;

    try {
        for (MultipartFile file : files) {
            tempFileName = "/tmp/" + file.getOriginalFilename();
            tempFileNames.add(tempFileName);
            fo = new FileOutputStream(tempFileName);
            fo.write(file.getBytes());
            fo.close();
            map.add("files", new FileSystemResource(tempFileName));
        }

        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.MULTIPART_FORM_DATA);

        HttpEntity<LinkedMultiValueMap<String, Object>> requestEntity = new HttpEntity<>(map, headers);
        String response = restTemplate.postForObject(uploadFilesUrl, requestEntity, String.class);

    } catch (IOException e) {
        e.printStackTrace();
    }

    for (String fileName : tempFileNames) {
        File f = new File(fileName);
        f.delete();
    }
    return new ResponseEntity<Object>(HttpStatus.OK);
}

Here is tutorial how to do that (CATALINA_HOME is path to your Tomcat, so I suppose something like C:/Program Files/Tomcat/. And for starting server, you need to execute script startup.bat from command line, this will make it:)

For php 7.1

sudo apt-get install php7.1-mbstring

Cheers!

Depends on what your target browsers are. In newer ones it's as simple as:

   -moz-box-shadow: 0 0 5px #fff;
-webkit-box-shadow: 0 0 5px #fff;
        box-shadow: 0 0 5px #fff;

For older browsers you have to implement workarounds, e.g., based on this example, but you will most probably need extra mark-up.

You can use compileall in the terminal. The following command will go recursively into sub directories and make pyc files for all the python files it finds. The compileall module is part of the python standard library, so you don't need to install anything extra to use it. This works exactly the same way for python2 and python3.

python -m compileall .

You can use template facility in C++ to do this. I did something like this :

template<typename T, size_t col>
T process(T a[][col], size_t row) {
...
}

the problem with this approach is that for every value of col which you provide, the a new function definition is instantiated using the template. so,

int some_mat[3][3], another_mat[4,5];
process(some_mat, 3);
process(another_mat, 4);

instantiates the template twice to produce 2 function definitions (one where col = 3 and one where col = 5).

The next link will bring you to a great tutorial, that helped me a lot!

How to SQLITE in C#

I nearly used everything in that article to create the SQLite database for my own C# Application.

Don't forget to download the SQLite.dll, and add it as a reference to your project. This can be done using NuGet and by adding the dll manually.

After you added the reference, refer to the dll from your code using the following line on top of your class:

using System.Data.SQLite;

You can find the dll's here:

SQLite DLL's

You can find the NuGet way here:

NuGet

Up next is the create script. Creating a database file:

SQLiteConnection.CreateFile("MyDatabase.sqlite");

SQLiteConnection m_dbConnection = new SQLiteConnection("Data Source=MyDatabase.sqlite;Version=3;");
m_dbConnection.Open();

string sql = "create table highscores (name varchar(20), score int)";

SQLiteCommand command = new SQLiteCommand(sql, m_dbConnection);
command.ExecuteNonQuery();

sql = "insert into highscores (name, score) values ('Me', 9001)";

command = new SQLiteCommand(sql, m_dbConnection);
command.ExecuteNonQuery();

m_dbConnection.Close();

After you created a create script in C#, I think you might want to add rollback transactions, it is safer and it will keep your database from failing, because the data will be committed at the end in one big piece as an atomic operation to the database and not in little pieces, where it could fail at 5th of 10 queries for example.

Example on how to use transactions:

 using (TransactionScope tran = new TransactionScope())
 {
     //Insert create script here.

     //Indicates that creating the SQLiteDatabase went succesfully, so the database can be committed.
     tran.Complete();
 }

Like Unix shells, PowerShell supports > redirects with most of the variations known from Unix, including 2>&1 (though weirdly, order doesn't matter - 2>&1 > file works just like the normal > file 2>&1).

Like most modern Unix shells, PowerShell also has a shortcut for redirecting both standard error and standard output to the same device, though unlike other redirection shortcuts that follow pretty much the Unix convention, the capture all shortcut uses a new sigil and is written like so: *>.

So your implementation might be:

& myjob.bat *>> $logfile

final class PagingFlowLayout: UICollectionViewFlowLayout {
    private var currentIndex = 0

    override func targetContentOffset(forProposedContentOffset proposedContentOffset: CGPoint, withScrollingVelocity velocity: CGPoint) -> CGPoint {
        let count = collectionView!.numberOfItems(inSection: 0)
        let currentAttribute = layoutAttributesForItem(
            at: IndexPath(item: currentIndex, section: 0)
            ) ?? UICollectionViewLayoutAttributes()

        let direction = proposedContentOffset.x > currentAttribute.frame.minX
        if collectionView!.contentOffset.x + collectionView!.bounds.width < collectionView!.contentSize.width || currentIndex < count - 1 {
            currentIndex += direction ? 1 : -1
            currentIndex = max(min(currentIndex, count - 1), 0)
        }

        let indexPath = IndexPath(item: currentIndex, section: 0)
        let closestAttribute = layoutAttributesForItem(at: indexPath) ?? UICollectionViewLayoutAttributes()

        let centerOffset = collectionView!.bounds.size.width / 2
        return CGPoint(x: closestAttribute.center.x - centerOffset, y: 0)
    }
}

Turning PAE/NX on/off didn't work for me. I just needed to turn on virtualization on my computer. I was working on a HP Compaq 8200 and followed the steps below to turn on virtualization. If you are working on a different computer, you probably just need to look up how to turn on virtualization on your pc. The steps below for HP Compaq 8200 (or similar) is copied verbatim from the comment posted by the user qqdmax5 on Hp discussion board here.

To run Oracle VM Virtual Box / VMware machines on 64-bit host there is a need to enable Virtualization Technology (VTx) and Virtualization Technology Directed I/O (VTd).

Usually these setting are disabled on the level of BIOS.

To enable VTx and VTd you have to change corresponding settings in the BIOS.

Here is an example how to do it for HP Compaq 8200 or similar PC:

1. Start the machine.
2. Press F10 to enter BIOS.
3. Security-> System Security
4. Enable Virtualization Technology (VTx) and Virtualization Technology Directed I/O (VTd).
5. Save and restart the machine.

There is also some discussion on this on askubuntu.

Use cl scr on the Sql* command line tool to clear all the matter on the screen.

Less efficient, but simpler-looking:

m0 = re.match("I love (\w+)", statement)
m1 = re.match("Ich liebe (\w+)", statement)
m2 = re.match("Je t'aime (\w+)", statement)
if m0:
  print "He loves",m0.group(1)
elif m1:
  print "Er liebt",m1.group(1)
elif m2:
  print "Il aime",m2.group(1)

The problem with the Perl stuff is the implicit updating of some hidden variable. That's simply hard to achieve in Python because you need to have an assignment statement to actually update any variables.

The version with less repetition (and better efficiency) is this:

pats = [
    ("I love (\w+)", "He Loves {0}" ),
    ("Ich liebe (\w+)", "Er Liebe {0}" ),
    ("Je t'aime (\w+)", "Il aime {0}")
 ]
for p1, p3 in pats:
    m= re.match( p1, statement )
    if m:
        print p3.format( m.group(1) )
        break

A minor variation that some Perl folk prefer:

pats = {
    "I love (\w+)" : "He Loves {0}",
    "Ich liebe (\w+)" : "Er Liebe {0}",
    "Je t'aime (\w+)" : "Il aime {0}",
}
for p1 in pats:
    m= re.match( p1, statement )
    if m:
        print pats[p1].format( m.group(1) )
        break

This is hardly worth mentioning except it does come up sometimes from Perl programmers.

Here's an example of two applications in one html page and two conrollers in one application :

    <div ng-app = "myapp">
      <div  ng-controller = "C1" id="D1">
         <h2>controller 1 in app 1 <span id="titre">{{s1.title}}</span> !</h2>
      </div>

      <div  ng-controller = "C2" id="D2">
         <h2>controller 2 in app 1 <span id="titre">{{s2.valeur}}</span> !</h2>
      </div>
    </div>
    <script>
        var A1 = angular.module("myapp", [])

        A1.controller("C1", function($scope) {
            $scope.s1 = {};
            $scope.s1.title = "Titre 1";
         });

        A1.controller("C2", function($scope) {
            $scope.s2 = {};
            $scope.s2.valeur = "Valeur 2";
         });
    </script>

    <div ng-app="toapp" ng-controller="C1" id="App2">
        <br>controller 1 in app 2
        <br>First Name: <input type = "text" ng-model = "student.firstName">
        <br>Last Name : <input type="text" ng-model="student.lastName">
        <br>Hello : {{student.fullName()}}
        <br>
    </div>

    <script>
        var A2 = angular.module("toapp", []);
        A2.controller("C1", function($scope) {
            $scope.student={
                firstName:"M",
                lastName:"E",
                fullName:function(){
                    var so=$scope.student;
                    return so.firstName+" "+so.lastName;
                }
            };
        });
        angular.bootstrap(document.getElementById("App2"), ['toapp']);
    </script>
<style>
    #titre{color:red;}
    #D1{ background-color:gray; width:50%; height:20%;}
    #D2{ background-color:yellow; width:50%; height:20%;}
    input{ font-weight: bold; }
</style>

I will answer your question using a math analogy:

In this instance, the number 0 will represent no value. If you pick a random number, say 15, how many times can 0 be subtracted from 15? Infinite times because 0 has no value, thus you are taking nothing out of 15. Do you have difficulty accepting that 15 - 0 = 15 instead of ERROR? So if we switch this analogy back to Java coding, the String "" represents no value. Pick a random string, say "hello world", how many times can "" be subtracted from "hello world"?

You absolutely need to know where the files to be read can be located. However, this information can be relative of course so it may be well adapted to other systems.

So it could relate to the current directory (get it from Directory.GetCurrentDirectory()) or to the application executable path (eg. Application.ExecutablePath comes to mind if using Windows Forms or via Assembly.GetEntryAssembly().Location) or to some special Windows directory like "Documents and Settings" (you should use Environment.GetFolderPath() with one element of the Environment.SpecialFolder enumeration).

Note that the "current directory" and the path of the executable are not necessarily identical. You need to know where to look!

In either case, if you need to manipulate a path use the Path class to split or combine parts of the path.

In WAMP 3.1.4 x64 I solved updating the file C:\wamp64\alias\phpmyadmin.conf from this:

Alias /phpmyadmin "c:/wamp64/apps/phpmyadmin4.8.3/"

<Directory "c:/wamp64/apps/phpmyadmin4.8.3/">
    Options +Indexes +FollowSymLinks +MultiViews
  AllowOverride all
  <ifDefine APACHE24>
        Require local
    </ifDefine>
    <ifDefine !APACHE24>
        Order Deny,Allow
    Deny from all
    Allow from localhost ::1 127.0.0.1
    </ifDefine>

# To import big file you can increase values
  php_admin_value upload_max_filesize 128M
  php_admin_value post_max_size 128M
  php_admin_value max_execution_time 360
  php_admin_value max_input_time 360
</Directory>

to this:

Alias /phpmyadmin "c:/wamp64/apps/phpmyadmin4.8.3/"

<Directory "c:/wamp64/apps/phpmyadmin4.8.3/">
    Options +Indexes +FollowSymLinks +MultiViews

  php_admin_value post_max_size 128M
  php_admin_value max_execution_time 360
  php_admin_value max_input_time 360
</Directory>

And finally restarting all WAMP services.

Do you really need to do that programmatically?

Just considering the title: You could use a ShapeDrawable as android:background…

For example, let's define res/drawable/my_custom_background.xml as:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="rectangle">
  <corners
      android:radius="2dp"
      android:topRightRadius="0dp"
      android:bottomRightRadius="0dp"
      android:bottomLeftRadius="0dp" />
  <stroke
      android:width="1dp"
      android:color="@android:color/white" />
</shape>

and define android:background="@drawable/my_custom_background".

I've not tested but it should work.

Update:

I think that's better to leverage the xml shape drawable resource power if that fits your needs. With a "from scratch" project (for android-8), define res/layout/main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/border"
    android:padding="10dip" >
    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Hello World, SOnich"
        />
    [... more TextView ...]
    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Hello World, SOnich"
        />
</LinearLayout>

and a res/drawable/border.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="rectangle">
   <stroke
        android:width="5dip"

Reported to work on a gingerbread device. Note that you'll need to relate android:padding of the LinearLayout to the android:width shape/stroke's value. Please, do not use @android:color/white in your final application but rather a project defined color.

You could apply android:background="@drawable/border" android:padding="10dip" to each of the LinearLayout from your provided sample.

As for your other posts related to display some circles as LinearLayout's background, I'm playing with Inset/Scale/Layer drawable resources (see Drawable Resources for further information) to get something working to display perfect circles in the background of a LinearLayout but failed at the moment…

Your problem resides clearly in the use of getBorder.set{Width,Height}(100);. Why do you do that in an onClick method?

I need further information to not miss the point: why do you do that programmatically? Do you need a dynamic behavior? Your input drawables are png or ShapeDrawable is acceptable? etc.

To be continued (maybe tomorrow and as soon as you provide more precisions on what you want to achieve)…

It’s a chicken-and-egg problem. You won’t be able to do it because you need to load the assets to display the progress bar widget, by which time your page will be either fully or partially downloaded. Also, you need to know the total size of the page prior to the user requesting in order to calculate a percentage.

It’s more hassle than it’s worth.

<form name="myForm" id="myForm" method="post" onsubmit="return validateForm();">
    First Name: <input type="text" id="name" /> <br />
    <span id="nameErrMsg" class="error"></span> <br />
    <!-- ... all your other stuff ... -->
</form>
  <p>
    1.word should be atleast 5 letter<br>
    2.No space should be encountered<br>
    3.No numbers and special characters allowed<br>
    4.letters can be repeated upto 3(eg: aa is allowed aaa is not allowed)
  </p>

    var input = x.name.value;
    var errMsgHolder = document.getElementById('nameErrMsg');
    if (input.length < 5) {
        errMsgHolder.innerHTML =
            'Please enter a name with at least 5 letters';
        return false;
    } else if (!(/^\S{3,}$/.test(input))) {

In Selenium IDE you can do:

Command   |   clickAndWait
Target    |   //input[@value='Next' and @title='next']

It should work fine.

Seems there's an easier way, at least in Kendo UI v2015.2.624:

$('#myDropDownSelector').data('kendoDropDownList').search('Text value to find');

If there's not a match in the dropdown, Kendo appears to set the dropdown to an unselected value, which makes sense.

I couldn't get @Gang's answer to work, but if you swap his value with search, as above, we're golden.

I think what you looking for is "joinSub". It's supported from laravel ^5.6. If you using laravel version below 5.6 you can also register it as macro in your app service provider file. like this https://github.com/teamtnt/laravel-scout-tntsearch-driver/issues/171#issuecomment-413062522

$subquery = DB::table('catch-text')
            ->select(DB::raw("user_id,MAX(created_at) as MaxDate"))
            ->groupBy('user_id');

$query = User::joinSub($subquery,'MaxDates',function($join){
          $join->on('users.id','=','MaxDates.user_id');
})->select(['users.*','MaxDates.*']);

Use stringObject.substring

if (pathname.substring(0, 6) == "/sub/1") {
    // ...
}

Call

Calls one batch program from another without stopping the parent batch program. The call command accepts labels as the target of the call. Call has no effect at the command-line when used outside of a script or batch file. https://technet.microsoft.com/en-us/library/bb490873.aspx

Start

Starts a separate Command Prompt window to run a specified program or command. Used without parameters, start opens a second command prompt window. https://technet.microsoft.com/en-us/library/bb491005.aspx

In fact, depends what you want to get: - Just the min value:

SELECT MIN(price) FROM pieces

• A table (multiples rows) whith the min value: Is as John Woo said above.

• But, if can be different rows with same min value, the best is ORDER them from another column, because after or later you will need to do it (starting from John Woo answere):

  SELECT * FROM pieces WHERE price = ( SELECT MIN(price) FROM pieces) ORDER BY stock ASC

Use the css "rotate()" method:

div {
  width: 100px;
  height: 100px;
  background-color: yellow;
  border: 1px solid black;
}

div#rotate{
  transform: rotate(90deg);
}

<div>
normal div
</div>
<br>

<div id="rotate">
This div is rotated 90 degrees
</div>

To download file on flask call. File name is Examples.pdf When I am hitting 127.0.0.1:5000/download it should get download.

Example:

from flask import Flask
from flask import send_file
app = Flask(__name__)

@app.route('/download')
def downloadFile ():
    #For windows you need to use drive name [ex: F:/Example.pdf]
    path = "/Examples.pdf"
    return send_file(path, as_attachment=True)

if __name__ == '__main__':
    app.run(port=5000,debug=True) 

It might seem logical to create a string with the desired variables, and pass it to os.system:

touch = 'touch ' + dir + '/' + fileName
os.system(touch)

This is inadequate in a number of ways (e.g.,it doesn't handle whitespace), so don't do it.

A more robust method is to use subprocess :

subprocess.call(['touch', os.path.join(dirname, fileName)])

While this is much better than using a subshell (with os.system), it is still only suitable for quick-and-dirty scripts; use the accepted answer for cross-platform programs.

In my case, I was using Laravel 5 and I had forgotten to change the mail globals in the .env file that is located in your directory root folder (these variables override your mail configuration)

   MAIL_DRIVER=smtp
   MAIL_HOST=smtp.gmail.com
   MAIL_PORT=465
   [email protected]
   MAIL_PASSWORD=yourpassword

by default, the mailhost is:

   MAIL_HOST=mailtraper.io

I was getting the same error but that worked for me.

I just wrote this one-liner to select the first empty cell found in a column based on a selected cell. Only works on first column of selected cells. Modify as necessary

Selection.End(xlDown).Range("A2").Select

For better output format check this command:

ps -fC java

I would rather put my answer in How to flush output of print function? or in Python's print function that flushes the buffer when it's called?, but since they were marked as duplicates of this one (what I do not agree), I'll answer it here.

Since Python 3.3, print() supports the keyword argument "flush" (see documentation):

print('Hello World!', flush=True)

Here is one more sample how to format duration. Note that this sample shows both positive and negative duration as positive duration.

import static java.time.temporal.ChronoUnit.DAYS;
import static java.time.temporal.ChronoUnit.HOURS;
import static java.time.temporal.ChronoUnit.MINUTES;
import static java.time.temporal.ChronoUnit.SECONDS;

import java.time.Duration;

public class DurationSample {
    public static void main(String[] args) {
        //Let's say duration of 2days 3hours 12minutes and 46seconds
        Duration d = Duration.ZERO.plus(2, DAYS).plus(3, HOURS).plus(12, MINUTES).plus(46, SECONDS);

        //in case of negative duration
        if(d.isNegative()) d = d.negated();

        //format DAYS HOURS MINUTES SECONDS 
        System.out.printf("Total duration is %sdays %shrs %smin %ssec.\n", d.toDays(), d.toHours() % 24, d.toMinutes() % 60, d.getSeconds() % 60);

        //or format HOURS MINUTES SECONDS 
        System.out.printf("Or total duration is %shrs %smin %sec.\n", d.toHours(), d.toMinutes() % 60, d.getSeconds() % 60);

        //or format MINUTES SECONDS 
        System.out.printf("Or total duration is %smin %ssec.\n", d.toMinutes(), d.getSeconds() % 60);

        //or format SECONDS only 
        System.out.printf("Or total duration is %ssec.\n", d.getSeconds());
    }
}

In my case, locking and unlocking login-keychain from Keychain Access did the trick

This might be seen as a little complex but does exactly what you want

SELECT 
  DISTINCT(p.`ProductID`) AS ProductID,
  SUM(pl.CashAmount) AS Cash,
  SUM(pr.CashAmount) AS `Check`,
  SUM(px.CashAmount) AS `Credit Card`,
  SUM(pl.CashAmount) + SUM(pr.CashAmount) +SUM(px.CashAmount) AS Amount
FROM
  `payments` AS p 
  LEFT JOIN (SELECT ProductID,PaymentMethod , IFNULL(Amount,0) AS CashAmount FROM payments WHERE PaymentMethod = 'Cash' GROUP BY ProductID , PaymentMethod ) AS pl 
    ON pl.`PaymentMethod` = p.`PaymentMethod` AND pl.ProductID = p.`ProductID`
  LEFT JOIN (SELECT ProductID,PaymentMethod , IFNULL(Amount,0) AS CashAmount FROM payments WHERE PaymentMethod = 'Check' GROUP BY ProductID , PaymentMethod) AS pr 
    ON pr.`PaymentMethod` = p.`PaymentMethod` AND pr.ProductID = p.`ProductID`
  LEFT JOIN (SELECT ProductID, PaymentMethod , IFNULL(Amount,0) AS CashAmount FROM payments WHERE PaymentMethod = 'Credit Card' GROUP BY ProductID , PaymentMethod) AS px 
    ON px.`PaymentMethod` = p.`PaymentMethod` AND px.ProductID = p.`ProductID`
GROUP BY p.`ProductID` ;

Output

ProductID | Cash | Check | Credit Card | Amount
-----------------------------------------------
    3     | 20   |  15   |   25        |  60
    4     | 5    |  6    |   7         |  18

SQL Fiddle Demo

Yeah Got it...

Date dob=null;
DateFormat df=new SimpleDateFormat("dd/MM/yyyy");
dob=df.parse( "13/06/1983" );
GregorianCalendar cal = new GregorianCalendar();
cal.setTime(dob);
XMLGregorianCalendar xmlDate = DatatypeFactory.newInstance().newXMLGregorianCalendarDate(cal.get(Calendar.YEAR), cal.get(Calendar.MONTH)+1, cal.get(Calendar.DAY_OF_MONTH), DatatypeConstants.FIELD_UNDEFINED);

This will give it in correct format.

for any1 using ie8 and dont want to use a plugin i've made something inspired by Rohit Azad and Bacotasan's blog, i just added a span using JS to show the selected value.

the html:

<div class="styled-select">
   <select>
      <option>Here is the first option</option>
      <option>The second option</option>
   </select>
   <span>Here is the first option</span>
</div>

the css (i used only an arrow for BG but you could put a full image and drop the positioning):

.styled-select div
{
    display:inline-block;
    border: 1px solid darkgray;
    width:100px;
    background:url("/Style Library/Nifgashim/Images/drop_arrrow.png") no-repeat 10px 10px;
    position:relative;
}

.styled-select div select
{
    height: 30px;
    width: 100px;
    font-size:14px;
    font-family:ariel;

    -moz-opacity: 0.00;
    opacity: .00;
    filter: alpha(opacity=00);
}

.styled-select div span
{
    position: absolute;
    right: 10px;
    top: 6px;
    z-index: -5;
}

the js:

$(".styled-select select").change(function(e){
     $(".styled-select span").html($(".styled-select select").val());
});

I thought it was Shift + Tab.

It's always enlightening to do a benchmark on the various suggested answers. Here's what I found out:

#!/usr/bin/ruby

require 'benchmark'

ary = []
1000.times { 
  ary << {:bar => rand(1000)} 
}

n = 500
Benchmark.bm(20) do |x|
  x.report("sort")               { n.times { ary.sort{ |a,b| b[:bar] <=> a[:bar] } } }
  x.report("sort reverse")       { n.times { ary.sort{ |a,b| a[:bar] <=> b[:bar] }.reverse } }
  x.report("sort_by -a[:bar]")   { n.times { ary.sort_by{ |a| -a[:bar] } } }
  x.report("sort_by a[:bar]*-1") { n.times { ary.sort_by{ |a| a[:bar]*-1 } } }
  x.report("sort_by.reverse!")   { n.times { ary.sort_by{ |a| a[:bar] }.reverse } }
end

                          user     system      total        real
sort                  3.960000   0.010000   3.970000 (  3.990886)
sort reverse          4.040000   0.000000   4.040000 (  4.038849)
sort_by -a[:bar]      0.690000   0.000000   0.690000 (  0.692080)
sort_by a[:bar]*-1    0.700000   0.000000   0.700000 (  0.699735)
sort_by.reverse!      0.650000   0.000000   0.650000 (  0.654447)

I think it's interesting that @Pablo's sort_by{...}.reverse! is fastest. Before running the test I thought it would be slower than "-a[:bar]" but negating the value turns out to take longer than it does to reverse the entire array in one pass. It's not much of a difference, but every little speed-up helps.

Please note that these results are different in Ruby 1.9

Here are results for Ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin10.8.0]:

                           user     system      total        real
sort                   1.340000   0.010000   1.350000 (  1.346331)
sort reverse           1.300000   0.000000   1.300000 (  1.310446)
sort_by -a[:bar]       0.430000   0.000000   0.430000 (  0.429606)
sort_by a[:bar]*-1     0.420000   0.000000   0.420000 (  0.414383)
sort_by.reverse!       0.400000   0.000000   0.400000 (  0.401275)

These are on an old MacBook Pro. Newer, or faster machines, will have lower values, but the relative differences will remain.

Here's a bit updated version on newer hardware and the 2.1.1 version of Ruby:

#!/usr/bin/ruby

require 'benchmark'

puts "Running Ruby #{RUBY_VERSION}"

ary = []
1000.times {
  ary << {:bar => rand(1000)}
}

n = 500

puts "n=#{n}"
Benchmark.bm(20) do |x|
  x.report("sort")               { n.times { ary.dup.sort{ |a,b| b[:bar] <=> a[:bar] } } }
  x.report("sort reverse")       { n.times { ary.dup.sort{ |a,b| a[:bar] <=> b[:bar] }.reverse } }
  x.report("sort_by -a[:bar]")   { n.times { ary.dup.sort_by{ |a| -a[:bar] } } }
  x.report("sort_by a[:bar]*-1") { n.times { ary.dup.sort_by{ |a| a[:bar]*-1 } } }
  x.report("sort_by.reverse")    { n.times { ary.dup.sort_by{ |a| a[:bar] }.reverse } }
  x.report("sort_by.reverse!")   { n.times { ary.dup.sort_by{ |a| a[:bar] }.reverse! } }
end

New results running the above code using Ruby 2.2.1 on a more recent Macbook Pro. Again, the exact numbers aren't important, it's their relationships:

...the reverse method doesn't actually return a reversed array - it returns an enumerator that just starts at the end and works backwards.

The source for Array#reverse is:

               static VALUE
rb_ary_reverse_m(VALUE ary)
{
    long len = RARRAY_LEN(ary);
    VALUE dup = rb_ary_new2(len);

    if (len > 0) {
        const VALUE *p1 = RARRAY_CONST_PTR_TRANSIENT(ary);
        VALUE *p2 = (VALUE *)RARRAY_CONST_PTR_TRANSIENT(dup) + len - 1;
        do *p2-- = *p1++; while (--len > 0);
    }
    ARY_SET_LEN(dup, RARRAY_LEN(ary));
    return dup;
}

do *p2-- = *p1++; while (--len > 0); is copying the pointers to the elements in reverse order if I remember my C correctly, so the array is reversed.

Local variables are automatically freed when the function ends, you don't need to free them by yourself. You only free dynamically allocated memory (e.g using malloc) as it's allocated on the heap:

char *arr = malloc(3 * sizeof(char));
strcpy(arr, "bo");
// ...
free(arr);

More about dynamic memory allocation: http://en.wikipedia.org/wiki/C_dynamic_memory_allocation

You can change the passwd file directly for the particular user or use the below command

chsh -s /usr/local/bin/bash username

Then log out and log in

Thanks for the answer. I just got this working on Windows XP, with a few modifications. Here are my steps.

1. Download and install latest xampp to G:\xampp. As of 2010/03/12, this is 1.7.3.
2. Download the zip of xampp-win32-1.7.0.zip, which is the latest xampp distro without php 5.3. Extract somewhere, e.g. G:\xampp-win32-1.7.0\
3. Remove directory G:\xampp\php
4. Remove G:\xampp\apache\modules\php5apache2_2.dll and php5apache2_2_filter.dll
5. Copy G:\xampp-win32-1.7.0\xampp\php to G:\xampp\php.
6. Copy G:\xampp-win32-1.7.0\xampp\apache\bin\php* to G:\xampp\apache\bin
7. Edit G:\xampp\apache\conf\extra\httpd-xampp.conf.
   • Immediately after the line, <IfModule alias_module> add the lines

(snip)

<IfModule mime_module>
  LoadModule php5_module "/xampp/apache/bin/php5apache2_2.dll"
  AddType application/x-httpd-php-source .phps
  AddType application/x-httpd-php .php .php5 .php4 .php3 .phtml .phpt
    <Directory "/xampp/htdocs/xampp">
      <IfModule php5_module>
        <Files "status.php">
            php_admin_flag safe_mode off
        </Files>
      </IfModule>
    </Directory>
</IfModule>

(Note that this is taken from the same file in the 1.7.0 xampp distribution. If you run into trouble, check that conf file and make the new one match it.)

You should then be able to start the apache server with PHP 5.2.8. You can tail the G:\xampp\apache\logs\error.log file to see whether there are any errors on startup. If not, you should be able to see the XAMPP splash screen when you navigate to localhost.

Hope this helps the next guy.

cheers,

Jake

In my case port 8080 are already use by my local xampp server during oracle installation software check un used port like pop window appear for me

so for me url is http://127.0.0.1:8081/apex/f?p=4950:1:4076881202565564

try this new DecimalFormat("#.00");

update:

    double angle = 20.3034;

    DecimalFormat df = new DecimalFormat("#.00");
    String angleFormated = df.format(angle);
    System.out.println(angleFormated); //output 20.30

Your code wasn't using the decimalformat correctly

The 0 in the pattern means an obligatory digit, the # means optional digit.

update 2: check bellow answer

If you want 0.2677 formatted as 0.27 you should use new DecimalFormat("0.00"); otherwise it will be .27

This is precisely what the member function std::vector::insert is for

std::vector<int> AB = A;
AB.insert(AB.end(), B.begin(), B.end());

I ran into a very obscure and annoying cause of error 6. After goofing around with some NFS mounted volumes, uploads started failing. Problem resolved by restarting services

Actually it seems like Genymotion has an issue with the newer versions of Virtual box, I had the same issue on my Mac but when I downgraded to 4.3.30 it worked like a charm.

If your XML goes quite deep, you might want to consider using XPath, which comes with your JRE, so you can access the contents far more easily using:

String text = xp.evaluate("//add[@job='351']/tag[position()=1]/text()", 
    document.getDocumentElement());

Full example:

import static org.junit.Assert.assertEquals;
import java.io.StringReader;    
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.xpath.XPath;
import javax.xml.xpath.XPathFactory;    
import org.junit.Before;
import org.junit.Test;
import org.w3c.dom.Document;
import org.xml.sax.InputSource;

public class XPathTest {

    private Document document;

    @Before
    public void setup() throws Exception {
        String xml = "<add job=\"351\"><tag>foobar</tag><tag>foobar2</tag></add>";
        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        DocumentBuilder db = dbf.newDocumentBuilder();
        document = db.parse(new InputSource(new StringReader(xml)));
    }

    @Test
    public void testXPath() throws Exception {
        XPathFactory xpf = XPathFactory.newInstance();
        XPath xp = xpf.newXPath();
        String text = xp.evaluate("//add[@job='351']/tag[position()=1]/text()",
                document.getDocumentElement());
        assertEquals("foobar", text);
    }
}

The problem lays here:

--This result set has 3 columns
select LOC_id,LOC_locatie,LOC_deelVan_LOC_id from tblLocatie t
where t.LOC_id = 1 -- 1 represents an example

union all

--This result set has 1 columns   
select t.LOC_locatie + '>' from tblLocatie t
inner join q parent on parent.LOC_id = t.LOC_deelVan_LOC_id

In order to use union or union all number of columns and their types should be identical cross all result sets.

I guess you should just add the column LOC_deelVan_LOC_id to your second result set

If the answer from falsetru didn't work you could also try:

>>> b'a string'.decode('utf-8')
'a string'

you can simply do:

const objectDiff = (a, b)  => _.fromPairs(_.differenceWith(_.toPairs(a), _.toPairs(b), _.isEqual))

from Crypto import Random
from Crypto.Cipher import AES
import base64

BLOCK_SIZE=16
def trans(key):
     return md5.new(key).digest()

def encrypt(message, passphrase):
    passphrase = trans(passphrase)
    IV = Random.new().read(BLOCK_SIZE)
    aes = AES.new(passphrase, AES.MODE_CFB, IV)
    return base64.b64encode(IV + aes.encrypt(message))

def decrypt(encrypted, passphrase):
    passphrase = trans(passphrase)
    encrypted = base64.b64decode(encrypted)
    IV = encrypted[:BLOCK_SIZE]
    aes = AES.new(passphrase, AES.MODE_CFB, IV)
    return aes.decrypt(encrypted[BLOCK_SIZE:])

Heroku is like subset of AWS. It is just platform as a service, while AWS can be implemented as anything and at any level.

The implementation depends on what the business requirement. If it fits in either, use accordingly.

Quick'n'dirty you could create an hidden duplicate of the submit-button, which should be used, when pressing enter.

Example CSS

input.hidden {
    width: 0px;
    height: 0px;
    margin: 0px;
    padding: 0px;
    outline: none;
    border: 0px;
}

Example HTML

<input type="submit" name="next" value="Next" class="hidden" />
<input type="submit" name="prev" value="Previous" />
<input type="submit" name="next" value="Next" />

If someone now hits enter in your form, the (hidden) next-button will be used as submitter.

Tested on IE9, Firefox, Chrome and Opera

Use this regular expression to match square brackets or single quotes:

/[\[\]']+/g

Replace with the empty string.

console.log("['abc','xyz']".replace(/[\[\]']+/g,''));

Newer versions of MongoDB support bulk operations:

var col = db.collection('people');
var batch = col.initializeUnorderedBulkOp();

batch.insert({name: "John"});
batch.insert({name: "Jane"});
batch.insert({name: "Jason"});
batch.insert({name: "Joanne"});

batch.execute(function(err, result) {
    if (err) console.error(err);
    console.log('Inserted ' + result.nInserted + ' row(s).');
}

It seems like you don't have react-scripts in your global environment. Two possibility are available here :

npm install -g react-scripts

or in your package.json change your script part like this :

  "scripts": {
    "start": "./node_modules/react-scripts/bin/react-scripts.js start",
    "start:prod": "pushstate-server build",
    "build": "./node_modules/react-scripts/bin/react-scripts.js build",
    "test": "./node_modules/react-scripts/bin/react-scripts.js test --env=jsdom",
    "eject": "./node_modules/react-scripts/bin/react-scripts.js eject",
    "server": "cd client/api && pm2 start server.js --watch",
    "proxy": "http://128.199.139.144:3000"
  },

Perhaps with dataframes one of the most easy and practical solution is:

data = dplyr::mutate(data, rownum=row_number())

Use the files filelist of the element instead of val()

$("input[type=file]").on('change',function(){
    alert(this.files[0].name);
});

By default, a grid item cannot be smaller than the size of its content.

Grid items have an initial size of min-width: auto and min-height: auto.

You can override this behavior by setting grid items to min-width: 0, min-height: 0 or overflow with any value other than visible.

From the spec:

6.6. Automatic Minimum Size of Grid Items

To provide a more reasonable default minimum size for grid items, this specification defines that the auto value of min-width / min-height also applies an automatic minimum size in the specified axis to grid items whose overflow is visible. (The effect is analogous to the automatic minimum size imposed on flex items.)

Here's a more detailed explanation covering flex items, but it applies to grid items, as well:

• Why don't flex items shrink past content size?

This post also covers potential problems with nested containers and known rendering differences among major browsers.

To fix your layout, make these adjustments to your code:

.month-grid {
  display: grid;
  grid-template: repeat(6, 1fr) / repeat(7, 1fr);
  background: #fff;
  grid-gap: 2px;
  min-height: 0;  /* NEW */
  min-width: 0;   /* NEW; needed for Firefox */
}

.day-item {
  padding: 10px;
  background: #DFE7E7;
  overflow: hidden;  /* NEW */
  min-width: 0;      /* NEW; needed for Firefox */
}

jsFiddle demo

1fr vs minmax(0, 1fr)

The solution above operates at the grid item level. For a container level solution, see this post:

• Who does minmax(0, 1fr) work for long elements while 1fr doesn't?

According to What we talk about when we talk about monads the question "What is a monad" is wrong:

The short answer to the question "What is a monad?" is that it is a monoid in the category of endofunctors or that it is a generic data type equipped with two operations that satisfy certain laws. This is correct, but it does not reveal an important bigger picture. This is because the question is wrong. In this paper, we aim to answer the right question, which is "What do authors really say when they talk about monads?"

While that paper does not directly answer what a monad is it helps understanding what people with different backgrounds mean when they talk about monads and why.

Make (or rather a Makefile) is a buildsystem - it drives the compiler and other build tools to build your code.

CMake is a generator of buildsystems. It can produce Makefiles, it can produce Ninja build files, it can produce KDEvelop or Xcode projects, it can produce Visual Studio solutions. From the same starting point, the same CMakeLists.txt file. So if you have a platform-independent project, CMake is a way to make it buildsystem-independent as well.

If you have Windows developers used to Visual Studio and Unix developers who swear by GNU Make, CMake is (one of) the way(s) to go.

I would always recommend using CMake (or another buildsystem generator, but CMake is my personal preference) if you intend your project to be multi-platform or widely usable. CMake itself also provides some nice features like dependency detection, library interface management, or integration with CTest, CDash and CPack.

Using a buildsystem generator makes your project more future-proof. Even if you're GNU-Make-only now, what if you later decide to expand to other platforms (be it Windows or something embedded), or just want to use an IDE?

If you have a fixed navbar, you'll need something like this.

Taking from the best of the above answers and comments...

$(".bs-js-navbar-scrollspy li a[href^='#']").on('click', function(event) {
  var target = this.hash;

  event.preventDefault();

  var navOffset = $('#navbar').height();

  return $('html, body').animate({
    scrollTop: $(this.hash).offset().top - navOffset
  }, 300, function() {
    return window.history.pushState(null, null, target);
  });
});

First, in order to prevent the "undefined" error, store the hash to a variable, target, before calling preventDefault(), and later reference that stored value instead, as mentioned by pupadupa.

Next. You cannot use window.location.hash = target because it sets the url and the location simultaneously rather than separately. You will end up having the location at the beginning of the element whose id matches the href... but covered by your fixed top navbar.

In order to get around this, you set your scrollTop value to the vertical scroll location value of the target minus the height of your fixed navbar. Directly targeting that value maintains smooth scrolling, instead of adding an adjustment afterwards, and getting unprofessional-looking jitters.

You will notice the url doesn't change. To set this, use return window.history.pushState(null, null, target); instead, to manually add the url to the history stack.

Done!

Other notes:

1) using the .on method is the latest (as of Jan 2015) jquery method that is better than .bind or .live, or even .click for reasons I'll leave to you to find out.

2) the navOffset value can be within the function or outside, but you will probably want it outside, as you may very well reference that vertical space for other functions / DOM manipulations. But I left it inside to make it neatly into one function.

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

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

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

You can proceed as follows to check whether a JToken Value is null

JToken token = jObject["key"];

if(token.Type == JTokenType.Null)
{
    // Do your logic
}

For XAMPP on MACOS or Linux, remove the semicolon in php.ini file after extension=curl.so

If you want to search on both FROM and TO airports, you'll want to join on the Airports table twice - then you can use both from and to tables in your results set:

SELECT
   Flights.*,fromAirports.*,toAirports.*
FROM
   Flights
INNER JOIN 
   Airports fromAirports on Flights.fairport = fromAirports.code
INNER JOIN 
   Airports toAirports on Flights.tairport = toAirports.code
WHERE
 ...

Select a series and look in the formula bar. The last argument is the plot order of the series. You can edit this formula just like any other, right in the formula bar.

For example, select series 4, then change the 4 to a 3.

If you're using more recent Android APIs the Handler empty constructor has been deprecated and you should include a Looper. You can easily get one through Looper.getMainLooper().

    Handler(Looper.getMainLooper()).postDelayed({
        //Your code
    }, 2000) //millis

Try this (via a shell):

update db
locate index.html

Or:

find /var -iname "index.html"

Replace /var with your best guess as to the directory it is in but avoid starting from /

First checkout to the branch which you want to rename:

git branch -m old_branch new_branch
git push -u origin new_branch

To remove an old branch from remote:

git push origin :old_branch

In my case, with the same error exception, i put the "onBackPressed()" in a runnable (you can use any of your view):

myView.post(new Runnable() {
                    @Override
                    public void run() {
                        onBackPressed()
                    }
                });

I do not understand why, but it works!

Finally after comparing all solution, I think starting from build.gradle file can be convenient.

Gradle distribution has samples folder with a lot of examples, and there is gradle init --type basic comand see Chapter 47. Build Init Plugin. But they all needs some editing.

You can use template below as well, then run gradle initSourceFolders eclipse

/*
* Nodeclipse/Enide build.gradle template for basic Java project
*   https://github.com/Nodeclipse/nodeclipse-1/blob/master/org.nodeclipse.enide.editors.gradle/docs/java/basic/build.gradle
* Initially asked on
*   http://stackoverflow.com/questions/14017364/how-to-create-java-gradle-project
* Usage
*   1. create folder (or general Eclipse project) and put this file inside
*   2. run `gradle initSourceFolders eclipse` or `gradle initSourceFolders idea`
* @author Paul Verest; 
* based on `gradle init --type basic`, that does not create source folders 
*/

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'

task initSourceFolders { // add << before { to prevent executing during configuration phase
   sourceSets*.java.srcDirs*.each { it.mkdirs() }
   sourceSets*.resources.srcDirs*.each { it.mkdirs() }
}

task wrapper(type: Wrapper) {
    gradleVersion = '1.11'
}

// In this section you declare where to find the dependencies of your project
repositories {
    // Use Maven Central for resolving your dependencies.
    // You can declare any Maven/Ivy/file repository here.
    mavenCentral()
}

// In this section you declare the dependencies for your production and test code
dependencies {
    //compile fileTree(dir: 'libs', include: '*.jar')
    // The production code uses the SLF4J logging API at compile time
    //compile 'org.slf4j:slf4j-api:1.7.5'

    // Declare the dependency for your favourite test framework you want to use in your tests.
    // TestNG is also supported by the Gradle Test task. Just change the
    // testCompile dependency to testCompile 'org.testng:testng:6.8.1' and add
    // 'test.useTestNG()' to your build script.
    testCompile "junit:junit:4.11"
}

The result is like below.

That can be used without any Gradle plugin for Eclipse,
or with (Enide) Gradle for Eclipse, Jetty, Android alternative to Gradle Integration for Eclipse

1. First, launch your Safari browser from the Home screen and go to the webpage that you want to view full screen.

2. After locating the webpage, tap on the arrow icon at the top of your screen.

3. In the drop-down menu, tap on the Add to Home Screen option.

4. The Add to Home window should be displayed. You can customize the description that will appear as a title on the home screen of your iPad. When you are done, tap on the Add button.

5. A new icon should now appear on your home screen. Tapping on the icon will open the webpage in the fullscreen mode.

Note: The icon on your iPad home screen only opens the bookmarked page in the fullscreen mode. The next page you visit will be contain the Safari address and title bars. This way of playing your webpage or HTML5 presentation in the fullscreen mode works if the source code of the webpage contains the following tag:

<meta name="apple-mobile-web-app-capable" content="yes">

You can add this tag to your webpage using a third-party tool, for example iWeb SEO Tool or any other you like. Please note that you need to add the tag first, refresh the page and then add a bookmark to your home screen.

a <div> can be focused if it has a tabindex attribute. (the value can be set to -1)

For example:

$("#focus_point").attr("tabindex",-1).focus();

In addition, consider setting outline: none !important; so it displayed without a focus rectangle.

var element = $("#focus_point");
element.css('outline', 'none !important')
       .attr("tabindex", -1)
       .focus();

I made a class to manage this issue. This class set different margins for the items inside the recyclerView: only the first row will have a top margin and only the first column will have left margin.

public class RecyclerViewMargin extends RecyclerView.ItemDecoration {
private final int columns;
private int margin;

/**
 * constructor
 * @param margin desirable margin size in px between the views in the recyclerView
 * @param columns number of columns of the RecyclerView
 */
public RecyclerViewMargin(@IntRange(from=0)int margin ,@IntRange(from=0) int columns ) {
    this.margin = margin;
    this.columns=columns;

}

/**
 * Set different margins for the items inside the recyclerView: no top margin for the first row
 * and no left margin for the first column.
 */
@Override
public void getItemOffsets(Rect outRect, View view,
                           RecyclerView parent, RecyclerView.State state) {

    int position = parent.getChildLayoutPosition(view);
    //set right margin to all
    outRect.right = margin;
    //set bottom margin to all
    outRect.bottom = margin;
    //we only add top margin to the first row
    if (position <columns) {
        outRect.top = margin;
    }
    //add left margin only to the first column
    if(position%columns==0){
        outRect.left = margin;
        }
    }
}

you can set it in your recyclerview this way

 RecyclerViewMargin decoration = new RecyclerViewMargin(itemMargin, numColumns);
 recyclerView.addItemDecoration(decoration);

For anyone checking this question recently, Rails 5.2+ now has ActiveStorage by default & I highly recommend checking it out.

Since it is part of the core Rails 5.2+ now, it is very well integrated & has excellent capabilities out of the box (still all other well-known gems like Carrierwave, Shrine, paperclip,... are great but this one offers very good features that we can consider for any new Rails project)

Paperclip team deprecated the gem in favor of the Rails ActiveStorage.

Here is the github page for the ActiveStorage & plenty of resources are available everywhere

Also I found this video to be very helpful to understand the features of Activestorage

Have you tried https://www.virtualbox.org/manual/ch04.html which has step-by-step instructions to help you?

1. Make your VM bi-directional for Clipboard and Drag & Drop
2. Share folders from your host to the guest VM too.

In bootstrap 4, they have designed a bigger input file.

A simple solution to increase the size input file is to use font-size:

Add you style, for example:

input[type="file"] {
  font-size:35px
}

Otherwise, you can make one custom class and add to input control.

For Windows, I was able to get it working by enabling TLS for secure communication on the SMTP Virtual server. TLS will not be available on the SMTP virtual server without a certificate. This link will give the steps needed.

I found a more straight forward solution from @DK comment in this question, the solution is written by Alex and described here with source, To make customized window:

1. download the sample project here
2. edit the generic.xaml file to customize the layout.
3. enjoy :).

https://facebook.github.io/react/docs/jsx-in-depth.html#javascript-expressions

You can pass any JavaScript expression as children, by enclosing it within {}. For example, these expressions are equivalent:

<MyComponent>foo</MyComponent>

<MyComponent>{'foo'}</MyComponent>

This is often useful for rendering a list of JSX expressions of arbitrary length. For example, this renders an HTML list:

function Item(props) {
  return <li>{props.message}</li>;
}

function TodoList() {
  const todos = ['finish doc', 'submit pr', 'nag dan to review'];
  return (
    <ul>
      {todos.map((message) => <Item key={message} message={message} />)}
    </ul>
  );
}

class First extends React.Component {_x000D_
  constructor(props) {_x000D_
    super(props);_x000D_
    this.state = {_x000D_
      data: [{name: 'bob'}, {name: 'chris'}],_x000D_
    };_x000D_
  }_x000D_
  _x000D_
  render() {_x000D_
    return (_x000D_
      <ul>_x000D_
        {this.state.data.map(d => <li key={d.name}>{d.name}</li>)}_x000D_
      </ul>_x000D_
    );_x000D_
  }_x000D_
}_x000D_
_x000D_
ReactDOM.render(_x000D_
  <First />,_x000D_
  document.getElementById('root')_x000D_
);_x000D_
  

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.min.js"></script>_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react-dom.min.js"></script>_x000D_
<div id="root"></div>

This script will find files having a modification date of two minutes before and after the given date (and you can change the values in the conditions as per your requirement)

PATH_SRC="/home/celvas/Documents/Imp_Task/"
PATH_DST="/home/celvas/Downloads/zeeshan/"

cd $PATH_SRC
TODAY=$(date  -d "$(date +%F)" +%s)
TODAY_TIME=$(date -d "$(date +%T)" +%s)


for f in `ls`;
do
#       echo "File -> $f"
        MOD_DATE=$(stat -c %y "$f")
        MOD_DATE=${MOD_DATE% *}
#       echo MOD_DATE: $MOD_DATE
        MOD_DATE1=$(date -d "$MOD_DATE" +%s)
#       echo MOD_DATE: $MOD_DATE

DIFF_IN_DATE=$[ $MOD_DATE1 - $TODAY ]
DIFF_IN_DATE1=$[ $MOD_DATE1 - $TODAY_TIME ]
#echo DIFF: $DIFF_IN_DATE
#echo DIFF1: $DIFF_IN_DATE1
if [[ ($DIFF_IN_DATE -ge -120) && ($DIFF_IN_DATE1 -le 120) && (DIFF_IN_DATE1 -ge -120) ]]
then
echo File lies in Next Hour = $f
echo MOD_DATE: $MOD_DATE

#mv $PATH_SRC/$f  $PATH_DST/$f
fi
done

For example you want files having modification date before the given date only, you may change 120 to 0 in $DIFF_IN_DATE parameter discarding the conditions of $DIFF_IN_DATE1 parameter.

Similarly if you want files having modification date 1 hour before and after given date, just replace 120 by 3600 in if CONDITION.

My approach, i think coming more from an development than an operations point of view, is:

• Error means that the execution of some task could not be completed; an email couldn't be sent, a page couldn't be rendered, some data couldn't be stored to a database, something like that. Something has definitively gone wrong.
• Warning means that something unexpected happened, but that execution can continue, perhaps in a degraded mode; a configuration file was missing but defaults were used, a price was calculated as negative, so it was clamped to zero, etc. Something is not right, but it hasn't gone properly wrong yet - warnings are often a sign that there will be an error very soon.
• Info means that something normal but significant happened; the system started, the system stopped, the daily inventory update job ran, etc. There shouldn't be a continual torrent of these, otherwise there's just too much to read.
• Debug means that something normal and insignificant happened; a new user came to the site, a page was rendered, an order was taken, a price was updated. This is the stuff excluded from info because there would be too much of it.
• Trace is something i have never actually used.

The regex is [^\w\s\-]*:

\s is better to use instead of space (), because there might be a tab in the text.

In your code you are assigning a native method to a property of custom object. When you call support.animationFrame(function () {}) , it is executed in the context of current object (ie support). For the native requestAnimationFrame function to work properly, it must be executed in the context of window.

So the correct usage here is support.animationFrame.call(window, function() {});.

The same happens with alert too:

var myObj = {
  myAlert : alert //copying native alert to an object
};

myObj.myAlert('this is an alert'); //is illegal
myObj.myAlert.call(window, 'this is an alert'); // executing in context of window 

Another option is to use Function.prototype.bind() which is part of ES5 standard and available in all modern browsers.

var _raf = window.requestAnimationFrame ||
        window.mozRequestAnimationFrame ||
        window.webkitRequestAnimationFrame ||
        window.msRequestAnimationFrame ||
        window.oRequestAnimationFrame;

var support = {
   animationFrame: _raf ? _raf.bind(window) : null
};

After reading so many articles Stackoverflow posts and demo applications to check variable property attributes, I decided to put all the attributes information together:

1. atomic //default
2. nonatomic
3. strong=retain //default
4. weak
5. retain
6. assign //default
7. unsafe_unretained
8. copy
9. readonly
10. readwrite //default

Below is the detailed article link where you can find above mentioned all attributes, that will definitely help you. Many thanks to all the people who give best answers here!!

Variable property attributes or Modifiers in iOS

1.strong (iOS4 = retain )

• it says "keep this in the heap until I don't point to it anymore"
• in other words " I'am the owner, you cannot dealloc this before aim fine with that same as retain"
• You use strong only if you need to retain the object.
• By default all instance variables and local variables are strong pointers.
• We generally use strong for UIViewControllers (UI item's parents)
• strong is used with ARC and it basically helps you , by not having to worry about the retain count of an object. ARC automatically releases it for you when you are done with it.Using the keyword strong means that you own the object.

Example:

@property (strong, nonatomic) ViewController *viewController;

@synthesize viewController;

2.weak -

• it says "keep this as long as someone else points to it strongly"
• the same thing as assign, no retain or release
• A "weak" reference is a reference that you do not retain.
• We generally use weak for IBOutlets (UIViewController's Childs).This works because the child object only needs to exist as long as the parent object does.
• a weak reference is a reference that does not protect the referenced object from collection by a garbage collector.
• Weak is essentially assign, a unretained property. Except the when the object is deallocated the weak pointer is automatically set to nil

Example :

@property (weak, nonatomic) IBOutlet UIButton *myButton;

@synthesize myButton;

Strong & Weak Explanation, Thanks to BJ Homer:

Imagine our object is a dog, and that the dog wants to run away (be deallocated).

Strong pointers are like a leash on the dog. As long as you have the leash attached to the dog, the dog will not run away. If five people attach their leash to one dog, (five strong pointers to one object), then the dog will not run away until all five leashes are detached.

Weak pointers, on the other hand, are like little kids pointing at the dog and saying "Look! A dog!" As long as the dog is still on the leash, the little kids can still see the dog, and they'll still point to it. As soon as all the leashes are detached, though, the dog runs away no matter how many little kids are pointing to it.

As soon as the last strong pointer (leash) no longer points to an object, the object will be deallocated, and all weak pointers will be zeroed out.

When we use weak?

The only time you would want to use weak, is if you wanted to avoid retain cycles (e.g. the parent retains the child and the child retains the parent so neither is ever released).

3.retain = strong

• it is retained, old value is released and it is assigned retain specifies the new value should be sent
• retain on assignment and the old value sent -release
• retain is the same as strong.
• apple says if you write retain it will auto converted/work like strong only.
• methods like "alloc" include an implicit "retain"

Example:

@property (nonatomic, retain) NSString *name;

@synthesize name;

4.assign

• assign is the default and simply performs a variable assignment
• assign is a property attribute that tells the compiler how to synthesize the property's setter implementation
• I would use assign for C primitive properties and weak for weak references to Objective-C objects.

Example:

@property (nonatomic, assign) NSString *address;

@synthesize address;

$x is always a scalar. The hint is the sigil $: any variable (or dereferencing of some other type) starting with $ is a scalar. (See perldoc perldata for more about data types.)

A reference is just a particular type of scalar. The built-in function ref will tell you what kind of reference it is. On the other hand, if you have a blessed reference, ref will only tell you the package name the reference was blessed into, not the actual core type of the data (blessed references can be hashrefs, arrayrefs or other things). You can use Scalar::Util 's reftype will tell you what type of reference it is:

use Scalar::Util qw(reftype);

my $x = bless {}, 'My::Foo';
my $y = { };

print "type of x: " . ref($x) . "\n";
print "type of y: " . ref($y) . "\n";
print "base type of x: " . reftype($x) . "\n";
print "base type of y: " . reftype($y) . "\n";

...produces the output:

type of x: My::Foo
type of y: HASH
base type of x: HASH
base type of y: HASH

For more information about the other types of references (e.g. coderef, arrayref etc), see this question: How can I get Perl's ref() function to return REF, IO, and LVALUE? and perldoc perlref.

Note: You should not use ref to implement code branches with a blessed object (e.g. $ref($a) eq "My::Foo" ? say "is a Foo object" : say "foo not defined";) -- if you need to make any decisions based on the type of a variable, use isa (i.e if ($a->isa("My::Foo") { ... or if ($a->can("foo") { ...). Also see polymorphism.

Both the org.hibernate.Session API and javax.persistence.EntityManager API represent a context for dealing with persistent data.

This concept is called a persistence context. Persistent data has a state in relation to both a persistence context and the underlying database.

Minimal runnable POSIX read + write example

Usage:

1. get two computers on a LAN.

   For example, this will work if both computers are connected to your home router in most cases, which is how I tested it.

2. On the server computer:

   1. Find the server local IP with ifconfig, e.g. 192.168.0.10

   2. Run:

      ./server output.tmp 12345
      

3. On the client computer:

   printf 'ab\ncd\n' > input.tmp
   ./client input.tmp 192.168.0.10 12345
   

4. Outcome: a file output.tmp is created on the sever computer containing 'ab\ncd\n'!

Further comments

Possible improvements:

• Currently output.tmp gets overwritten each time a send is done.

  This begs for the creation of a simple protocol that allows to pass a filename so that multiple files can be uploaded, e.g.: filename up to the first newline character, max filename 256 chars, and the rest until socket closure are the contents. Of course, that would require sanitation to avoid a path transversal vulnerability.

  Alternatively, we could make a server that hashes the files to find filenames, and keeps a map from original paths to hashes on disk (on a database).

• Only one client can connect at a time.

  This is specially harmful if there are slow clients whose connections last for a long time: the slow connection halts everyone down.

  One way to work around that is to fork a process / thread for each accept, start listening again immediately, and use file lock synchronization on the files.

• Add timeouts, and close clients if they take too long. Or else it would be easy to do a DoS.

  poll or select are some options: How to implement a timeout in read function call?

A simple HTTP wget implementation is shown at: How to make an HTTP get request in C without libcurl?

Tested on Ubuntu 15.10.

An important difference is that some UARTs (16550 notably) will stop receiving characters immediately if their host instructs them to set DSR to be inactive. In contrast, characters will still be received if CTS is inactive. I believe that the intention here is that DSR indicates that the device is no longer listening and so sending any further characters is pointless, while CTS indicates that a buffer is getting full; the latter allows for a certain amount of 'skid' where the flow control line changed state between the DTE sampling it and the next character being transmitted. In (relatively) later devices that support a hardware FIFO it's possible that a number of characters could be transmitted after the DCE has set CTS to be inactive.

Can't tell you how many times this has caught. me.

Guid myGuid = Guid.NewGuid(); 

If you want to always display some value after decimal for example "12.00" or "12.23" Then use just like below , it worked for me

FormatNumber("145.231000",2) Which will display 145.23

FormatNumber("145",2) Which will display 145.00

What you can try is writing your code as normal for python using the normal input command. However the trick is to add at the beginning of you program the command input=raw_input.

Now all you have to do is disable (or enable) depending on if you're running in Python/IDLE or Terminal. You do this by simply adding '#' when needed.

Switched off for use in Python/IDLE

    #input=raw_input 

And of course switched on for use in terminal.

    input=raw_input 

I'm not sure if it will always work, but its a possible solution for simple programs or scripts.

There's an article on Code Project about using GDI+ for .NET to do photo resizing using, say, Bicubic interpolation.

There was also another article about this topic on another blog (MS employee, I think), but I can't find the link anywhere. :( Perhaps someone else can find it?

There's no need, just use fadeToggle() on the element:

$('#testElement').fadeToggle('fast');

Here's a demo.

As for the inverse, the function is inv(A), but I won't recommend using it, since for huge matrices it is very computationally costly and unstable. Instead, you should use an approximation to the inverse, or if you want to solve Ax = b you don't really need A^-1.

The legend titles can be labeled by specific aesthetic.

This can be achieved using the guides() or labs() functions from ggplot2 (more here and here). It allows you to add guide/legend properties using the aesthetic mapping.

Here's an example using the mtcars data set and labs():

ggplot(mtcars, aes(x=mpg, y=disp, size=hp, col=as.factor(cyl), shape=as.factor(gear))) +
  geom_point() +
  labs(x="miles per gallon", y="displacement", size="horsepower", 
       col="# of cylinders", shape="# of gears")

Answering the OP's question using guides():

# transforming the data from wide to long
require(reshape2)
dfm <- melt(df, id="TY")

# creating a scatterplot
ggplot(data = dfm, aes(x=TY, y=value, color=variable)) + 
  geom_point(size=5) +
  labs(title="Temperatures\n", x="TY [°C]", y="Txxx") +
  scale_color_manual(labels = c("T999", "T888"), values = c("blue", "red")) +
  theme_bw() +
  guides(color=guide_legend("my title"))  # add guide properties by aesthetic

EDIT: I just realised after reading your question again, that i did not answer your question. You want to enter multiple lines in the same plot. However, I'll leave it be, because this served me very well multiple times. I hope you find usefull someday

I found this a while back when learning python

import matplotlib.pyplot as plt
import matplotlib.gridspec as gridspec

fig = plt.figure() 
# create figure window

gs = gridspec.GridSpec(a, b)
# Creates grid 'gs' of a rows and b columns 


ax = plt.subplot(gs[x, y])
# Adds subplot 'ax' in grid 'gs' at position [x,y]


ax.set_ylabel('Foo') #Add y-axis label 'Foo' to graph 'ax' (xlabel for x-axis)


fig.add_subplot(ax) #add 'ax' to figure

you can make different sizes in one figure as well, use slices in that case:

 gs = gridspec.GridSpec(3, 3)
 ax1 = plt.subplot(gs[0,:]) # row 0 (top) spans all(3) columns

consult the docs for more help and examples. This little bit i typed up for myself once, and is very much based/copied from the docs as well. Hope it helps... I remember it being a pain in the #$% to get acquainted with the slice notation for the different sized plots in one figure. After that i think it's very simple :)

Next is a piece of code which uses csv module but extracts file.csv contents to a list of dicts using the first line which is a header of csv table

import csv
def csv2dicts(filename):
  with open(filename, 'rb') as f:
    reader = csv.reader(f)
    lines = list(reader)
    if len(lines) < 2: return None
    names = lines[0]
    if len(names) < 1: return None
    dicts = []
    for values in lines[1:]:
      if len(values) != len(names): return None
      d = {}
      for i,_ in enumerate(names):
        d[names[i]] = values[i]
      dicts.append(d)
    return dicts
  return None

if __name__ == '__main__':
  your_list = csv2dicts('file.csv')
  print your_list

Working from what you've given I'll assume you want to check that someone has NOT entered any letters other than the ones you've listed. For that to work you want to search for any characters other than those listed:

[^A-Za-z0-9_.]

And use that in a match in your code, something like:

if ( /[^A-Za-z0-9_.]/.match( your_input_string ) ) {
   alert( "you have entered invalid data" );
}

Hows that?

var list = new List<string>();
var queryable = list.AsQueryable();

Add a reference to: System.Linq

Besides the fact that the branch prediction may slow you down, a sorted array has another advantage:

You can have a stop condition instead of just checking the value, this way you only loop over the relevant data, and ignore the rest.
The branch prediction will miss only once.

 // sort backwards (higher values first), may be in some other part of the code
 std::sort(data, data + arraySize, std::greater<int>());

 for (unsigned c = 0; c < arraySize; ++c) {
       if (data[c] < 128) {
              break;
       }
       sum += data[c];               
 }

In addition to the answers above, you may also get that error when you have Windows Authenticaton set and :

• IIS is pointing to an empty folder.
• You do not have a default document set.

Here's how you can do that.

Writing the persistent cookie.

//create a cookie
HttpCookie myCookie = new HttpCookie("myCookie");

//Add key-values in the cookie
myCookie.Values.Add("userid", objUser.id.ToString());

//set cookie expiry date-time. Made it to last for next 12 hours.
myCookie.Expires = DateTime.Now.AddHours(12);

//Most important, write the cookie to client.
Response.Cookies.Add(myCookie);

Reading the persistent cookie.

//Assuming user comes back after several hours. several < 12.
//Read the cookie from Request.
HttpCookie myCookie = Request.Cookies["myCookie"];
if (myCookie == null)
{
    //No cookie found or cookie expired.
    //Handle the situation here, Redirect the user or simply return;
}

//ok - cookie is found.
//Gracefully check if the cookie has the key-value as expected.
if (!string.IsNullOrEmpty(myCookie.Values["userid"]))
{
    string userId = myCookie.Values["userid"].ToString();
    //Yes userId is found. Mission accomplished.
}

use RelativeLayout inside LinearLayout

example:

<LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent">
            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_centerVertical="true"
                android:text="Status"/>
        </RelativeLayout>
</LinearLayout>

try this.. instead of using re i think using split with strip is much better

def my_handle(self):
    sentence = ' hello  apple  '
    ' '.join(x.strip() for x in sentence.split())
#hello apple
    ''.join(x.strip() for x in sentence.split())
#helloapple

Unless you specify a severity of 20 or higher, raiserror will not stop execution. See the MSDN documentation.

The normal workaround is to include a return after every raiserror:

if @whoops = 1
    begin
    raiserror('Whoops!', 18, 1)
    return -1
    end

If you are using the Eclipse IDE, check your Debug/Run configuration. At Classpath tab, select the runner project and click Edit button. Only include exported entries must be checked.

PLOTYY allows two different y-axes. Or you might look into LayerPlot from the File Exchange. I guess I should ask if you've considered using HOLD or just rescaling the data and using regular old plot?

OLD, not what the OP was looking for: SUBPLOT allows you to break a figure window into multiple axes. Then if you want to have only one x-axis showing, or some other customization, you can manipulate each axis independently.

If you run your code from an installed package, make sure template files are present in directory <python root>/lib/site-packages/your-package/templates.

Some details:

In my case I was trying to run examples of project flask_simple_ui and jinja would always say

jinja2.exceptions.TemplateNotFound: form.html

The trick was that sample program would import installed package flask_simple_ui. And ninja being used from inside that package is using as root directory for lookup the package path, in my case ...python/lib/site-packages/flask_simple_ui, instead of os.getcwd() as one would expect.

To my bad luck, setup.py has a bug and doesn't copy any html files, including the missing form.html. Once I fixed setup.py, the problem with TemplateNotFound vanished.

I hope it helps someone.

Instead of using a submit button, try using a <button type="button">Submit</button>

You can then call a javascript function in the button, and after the alert popup is confirmed, you can manually submit the form with document.getElementById("form").submit(); ... so you'll need to name and id your form for that to work.

The correct recursive command is:

sudo chmod -R 755 /opt/lampp/htdocs

-R: change every sub folder including the current folder

$myVar = str_replace('/', '', $_SERVER[REQUEST_URI]);

With Firefox, Safari (and other Gecko based browsers) you can easily use textarea.selectionStart, but for IE that doesn't work, so you will have to do something like this:

function getCaret(node) {
  if (node.selectionStart) {
    return node.selectionStart;
  } else if (!document.selection) {
    return 0;
  }

  var c = "\001",
      sel = document.selection.createRange(),
      dul = sel.duplicate(),
      len = 0;

  dul.moveToElementText(node);
  sel.text = c;
  len = dul.text.indexOf(c);
  sel.moveStart('character',-1);
  sel.text = "";
  return len;
}

(complete code here)

I also recommend you to check the jQuery FieldSelection Plugin, it allows you to do that and much more...

Edit: I actually re-implemented the above code:

function getCaret(el) { 
  if (el.selectionStart) { 
    return el.selectionStart; 
  } else if (document.selection) { 
    el.focus(); 

    var r = document.selection.createRange(); 
    if (r == null) { 
      return 0; 
    } 

    var re = el.createTextRange(), 
        rc = re.duplicate(); 
    re.moveToBookmark(r.getBookmark()); 
    rc.setEndPoint('EndToStart', re); 

    return rc.text.length; 
  }  
  return 0; 
}

Check an example here.

A bit different opinion instead of storing the Fragments yourself just leave it to the FragmentManager and when you need to do something with the fragments look for them in the FragmentManager:

//make sure you have the right FragmentManager 
//getSupportFragmentManager or getChildFragmentManager depending on what you are using to manage this stack of fragments
List<Fragment> fragments = fragmentManager.getFragments();
if(fragments != null) {
   int count = fragments.size();
   for (int x = 0; x < count; x++) {
       Fragment fragment = fragments.get(x);
       //check if this is the fragment we want, 
       //it may be some other inspection, tag etc.
       if (fragment instanceof MyFragment) {
           //do whatever we need to do with it
       }

If you have a lot of Fragments and the cost of instanceof check may be not what you want, but it is good thing to have in mind that the FragmentManager already keeps account of Fragments.

As pointed out in a few other answers, you can iterate over all elements in a matrix A (of any dimension) using a linear index from 1 to numel(A) in a single for loop. There are also a couple of functions you can use: arrayfun and cellfun.

Let's first assume you have a function that you want to apply to each element of A (called my_func). You first create a function handle to this function:

fcn = @my_func;

If A is a matrix (of type double, single, etc.) of arbitrary dimension, you can use arrayfun to apply my_func to each element:

outArgs = arrayfun(fcn, A);

If A is a cell array of arbitrary dimension, you can use cellfun to apply my_func to each cell:

outArgs = cellfun(fcn, A);

The function my_func has to accept A as an input. If there are any outputs from my_func, these are placed in outArgs, which will be the same size/dimension as A.

One caveat on outputs... if my_func returns outputs of different sizes and types when it operates on different elements of A, then outArgs will have to be made into a cell array. This is done by calling either arrayfun or cellfun with an additional parameter/value pair:

outArgs = arrayfun(fcn, A, 'UniformOutput', false);
outArgs = cellfun(fcn, A, 'UniformOutput', false);

Sorting stability means that records with the same key retain their relative order before and after the sort.

So stability matters if, and only if, the problem you're solving requires retention of that relative order.

If you don't need stability, you can use a fast, memory-sipping algorithm from a library, like heapsort or quicksort, and forget about it.

If you need stability, it's more complicated. Stable algorithms have higher big-O CPU and/or memory usage than unstable algorithms. So when you have a large data set, you have to pick between beating up the CPU or the memory. If you're constrained on both CPU and memory, you have a problem. A good compromise stable algorithm is a binary tree sort; the Wikipedia article has a pathetically easy C++ implementation based on the STL.

You can make an unstable algorithm into a stable one by adding the original record number as the last-place key for each record.

I realize I am a little late here, (5 years or so), but I think there is a better answer than the accepted one as follows:

$("#addComment").click(function() {
    if(typeof TinyMCE === "undefined") {
        $.ajax({
            url: "tinymce.js",
            dataType: "script",
            cache: true,
            success: function() {
                TinyMCE.init();
            }
        });
    }
});

The getScript() function actually prevents browser caching. If you run a trace you will see the script is loaded with a URL that includes a timestamp parameter:

http://www.yoursite.com/js/tinymce.js?_=1399055841840

If a user clicks the #addComment link multiple times, tinymce.js will be re-loaded from a differently timestampped URL. This defeats the purpose of browser caching.

===

Alternatively, in the getScript() documentation there is a some sample code that demonstrates how to enable caching by creating a custom cachedScript() function as follows:

jQuery.cachedScript = function( url, options ) {

    // Allow user to set any option except for dataType, cache, and url
    options = $.extend( options || {}, {
        dataType: "script",
        cache: true,
        url: url
    });

    // Use $.ajax() since it is more flexible than $.getScript
    // Return the jqXHR object so we can chain callbacks
    return jQuery.ajax( options );
};

// Usage
$.cachedScript( "ajax/test.js" ).done(function( script, textStatus ) {
    console.log( textStatus );
});

===

Or, if you want to disable caching globally, you can do so using ajaxSetup() as follows:

$.ajaxSetup({
    cache: true
});

const getFirstWord = string => {
    const firstWord = [];
    for (let i = 0; i < string.length; i += 1) {
        if (string[i] === ' ') break;
        firstWord.push(string[i]);
    }
    return firstWord.join('');
};
console.log(getFirstWord('Hello World'));

or simplify it:

const getFirstWord = string => {
    const words = string.split(' ');
    return words[0];
};
console.log(getFirstWord('Hello World'));

To set a values above or below the range of the colormap, you'll want to use the set_over and set_under methods of the colormap. If you want to flag a particular value, mask it (i.e. create a masked array), and use the set_bad method. (Have a look at the documentation for the base colormap class: http://matplotlib.org/api/colors_api.html#matplotlib.colors.Colormap )

It sounds like you want something like this:

import matplotlib.pyplot as plt
import numpy as np

# Generate some data
x, y, z = np.random.random((3, 30))
z = z * 20 + 0.1

# Set some values in z to 0...
z[:5] = 0

cmap = plt.get_cmap('jet', 20)
cmap.set_under('gray')

fig, ax = plt.subplots()
cax = ax.scatter(x, y, c=z, s=100, cmap=cmap, vmin=0.1, vmax=z.max())
fig.colorbar(cax, extend='min')

plt.show()

To create elements with equal width using Flex, you should set to your's child (flex elements):

flex-basis: 25%;
flex-grow: 0;

It will give to all elements in row 25% width. They will not grow and go one by one.

The file name should have .properties extension and the base directory should be in classpath. Otherwise it can also be in a jar which is in classpath Relative to the directory in classpath the resource bundle can be specified with / or . separator. "." is preferred.

Once I faced with the issue when I did not know which the element currently stored in my variable (svg or html) but I needed to get it width and height. I created this function and want to share it:

function computeDimensions(selection) {
  var dimensions = null;
  var node = selection.node();

  if (node instanceof SVGGraphicsElement) { // check if node is svg element
    dimensions = node.getBBox();
  } else { // else is html element
    dimensions = node.getBoundingClientRect();
  }
  console.log(dimensions);
  return dimensions;
}

Little demo in the hidden snippet below. We handle click on the blue div and on the red svg circle with the same function.

var svg = d3.select('svg')
  .attr('width', 50)
  .attr('height', 50);

function computeDimensions(selection) {
    var dimensions = null;
  var node = selection.node();

  if (node instanceof SVGElement) {
    dimensions = node.getBBox();
  } else {
    dimensions = node.getBoundingClientRect();
  }
  console.clear();
  console.log(dimensions);
  return dimensions;
}

var circle = svg
    .append("circle")
    .attr("r", 20)
    .attr("cx", 30)
    .attr("cy", 30)
    .attr("fill", "red")
    .on("click", function() { computeDimensions(circle); });
    
var div = d3.selectAll("div").on("click", function() { computeDimensions(div) });

* {
  margin: 0;
  padding: 0;
  border: 0;
}

body {
  background: #ffd;
}

.div {
  display: inline-block;
  background-color: blue;
  margin-right: 30px;
  width: 30px;
  height: 30px;
}

<h3>
  Click on blue div block or svg circle
</h3>
<svg></svg>
<div class="div"></div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/d3/4.11.0/d3.min.js"></script>

You are using growthRate both as a variable name and a function name. The variable hides the function, and then you are trying to use the variable as if it was the function - that is not valid.

Rename the local variable.

Expanding on some other answers, this is what I do:

Setup the repo: git clone --mirror user@server:/url-to-repo.git

Then when you want to refresh the backup: git remote update from the clone location.

This backs up all branches and tags, including new ones that get added later, although it's worth noting that branches that get deleted do not get deleted from the clone (which for a backup may be a good thing).

This is atomic so doesn't have the problems that a simple copy would.

See http://www.garron.me/en/bits/backup-git-bare-repo.html

What I have is a script file that actually runs things. This scrip file might be relatively complicated. Let's call it "run_container". This script takes arguments from the command line:

run_container p1 p2 p3

A simple run_container might be:

#!/bin/bash
echo "argc = ${#*}"
echo "argv = ${*}"

What I want to do is, after "dockering" this I would like to be able to startup this container with the parameters on the docker command line like this:

docker run image_name p1 p2 p3

and have the run_container script be run with p1 p2 p3 as the parameters.

This is my solution:

Dockerfile:

FROM docker.io/ubuntu
ADD run_container /
ENTRYPOINT ["/bin/bash", "-c", "/run_container \"$@\"", "--"]

You are getting this error because the value cannot be found in the range. String or integer doesn't matter. Best thing to do in my experience is to do a check first to see if the value exists.

I used CountIf below, but there is lots of different ways to check existence of a value in a range.

Public Sub test()

Dim rng As Range
Dim aNumber As Long

aNumber = 666

Set rng = Sheet5.Range("B16:B615")

    If Application.WorksheetFunction.CountIf(rng, aNumber) > 0 Then

        rowNum = Application.WorksheetFunction.Match(aNumber, rng, 0)

    Else
        MsgBox aNumber & " does not exist in range " & rng.Address
    End If

End Sub

ALTERNATIVE WAY

Public Sub test()
    Dim rng As Range
    Dim aNumber As Variant
    Dim rowNum As Long

    aNumber = "2gg"

    Set rng = Sheet5.Range("B1:B20")

    If Not IsError(Application.Match(aNumber, rng, 0)) Then
        rowNum = Application.Match(aNumber, rng, 0)
        MsgBox rowNum
    Else
        MsgBox "error"
    End If
End Sub

OR

Public Sub test()
    Dim rng As Range
    Dim aNumber As Variant
    Dim rowNum As Variant

    aNumber = "2gg"

    Set rng = Sheet5.Range("B1:B20")

    rowNum = Application.Match(aNumber, rng, 0)

    If Not IsError(rowNum) Then
        MsgBox rowNum
    Else
        MsgBox "error"
    End If
End Sub

I think it is more pythonic:

aList.remove(123)
aList.insert(0, 2014)

more useful:

def shuffle(list, to_delete, to_shuffle, index):
    list.remove(to_delete)
    list.insert(index, to_shuffle)
    return

list = ['a', 'b']
shuffle(list, 'a', 'c', 0)
print list
>> ['c', 'b']

Setting up log4j logging for Tomcat is pretty simple. The following is quoted from http://tomcat.apache.org/tomcat-5.5-doc/logging.html :

1. Create a file called log4j.properties with the following content and save it into common/classes.

             log4j.rootLogger=DEBUG, R 
             log4j.appender.R=org.apache.log4j.RollingFileAppender 
             log4j.appender.R.File=${catalina.home}/logs/tomcat.log 
             log4j.appender.R.MaxFileSize=10MB 
             log4j.appender.R.MaxBackupIndex=10 
             log4j.appender.R.layout=org.apache.log4j.PatternLayout 
             log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n
   

2. Download Log4J (v1.2 or later) and place the log4j jar in $CATALINA_HOME/common/lib.

3. Download Commons Logging and place the commons-logging-x.y.z.jar (not commons-logging-api-x.y.z.jar) in $CATALINA_HOME/common/lib with the log4j jar.
4. Start Tomcat

There are many ways to achieve this but the easiest way in Python 3.6+, in my opinion, is this:

print(f"{1:03}")

You can use Arrow:

This is example from the docs, iterating over hours:

from arrow import Arrow

>>> start = datetime(2013, 5, 5, 12, 30)
>>> end = datetime(2013, 5, 5, 17, 15)
>>> for r in Arrow.range('hour', start, end):
...     print repr(r)
...
<Arrow [2013-05-05T12:30:00+00:00]>
<Arrow [2013-05-05T13:30:00+00:00]>
<Arrow [2013-05-05T14:30:00+00:00]>
<Arrow [2013-05-05T15:30:00+00:00]>
<Arrow [2013-05-05T16:30:00+00:00]>

To iterate over days, you can use like this:

>>> start = Arrow(2013, 5, 5)
>>> end = Arrow(2013, 5, 5)
>>> for r in Arrow.range('day', start, end):
...     print repr(r)

(Didn't check if you can pass datetime.date objects, but anyways Arrow objects are easier in general)

The guidance on not using a thread abort is controversial. I think there is still a place for it but in exceptional circumstance. However you should always attempt to design around it and see it as a last resort.

Example;

You have a simple windows form application that connects to a blocking synchronous web service. Within which it executes a function on the web service within a Parallel loop.

CancellationTokenSource cts = new CancellationTokenSource();
ParallelOptions po = new ParallelOptions();
po.CancellationToken = cts.Token;
po.MaxDegreeOfParallelism = System.Environment.ProcessorCount;

Parallel.ForEach(iListOfItems, po, (item, loopState) =>
{

    Thread.Sleep(120000); // pretend web service call

});

Say in this example, the blocking call takes 2 mins to complete. Now I set my MaxDegreeOfParallelism to say ProcessorCount. iListOfItems has 1000 items within it to process.

The user clicks the process button and the loop commences, we have 'up-to' 20 threads executing against 1000 items in the iListOfItems collection. Each iteration executes on its own thread. Each thread will utilise a foreground thread when created by Parallel.ForEach. This means regardless of the main application shutdown, the app domain will be kept alive until all threads have finished.

However the user needs to close the application for some reason, say they close the form. These 20 threads will continue to execute until all 1000 items are processed. This is not ideal in this scenario, as the application will not exit as the user expects and will continue to run behind the scenes, as can be seen by taking a look in task manger.

Say the user tries to rebuild the app again (VS 2010), it reports the exe is locked, then they would have to go into task manager to kill it or just wait until all 1000 items are processed.

I would not blame you for saying, but of course! I should be cancelling these threads using the CancellationTokenSource object and calling Cancel ... but there are some problems with this as of .net 4.0. Firstly this is still never going to result in a thread abort which would offer up an abort exception followed by thread termination, so the app domain will instead need to wait for the threads to finish normally, and this means waiting for the last blocking call, which would be the very last running iteration (thread) that ultimately gets to call po.CancellationToken.ThrowIfCancellationRequested. In the example this would mean the app domain could still stay alive for up to 2 mins, even though the form has been closed and cancel called.

Note that Calling Cancel on CancellationTokenSource does not throw an exception on the processing thread(s), which would indeed act to interrupt the blocking call similar to a thread abort and stop the execution. An exception is cached ready for when all the other threads (concurrent iterations) eventually finish and return, the exception is thrown in the initiating thread (where the loop is declared).

I chose not to use the Cancel option on a CancellationTokenSource object. This is wasteful and arguably violates the well known anti-patten of controlling the flow of the code by Exceptions.

Instead, it is arguably 'better' to implement a simple thread safe property i.e. Bool stopExecuting. Then within the loop, check the value of stopExecuting and if the value is set to true by the external influence, we can take an alternate path to close down gracefully. Since we should not call cancel, this precludes checking CancellationTokenSource.IsCancellationRequested which would otherwise be another option.

Something like the following if condition would be appropriate within the loop;

if (loopState.ShouldExitCurrentIteration || loopState.IsExceptional || stopExecuting) {loopState.Stop(); return;}

The iteration will now exit in a 'controlled' manner as well as terminating further iterations, but as I said, this does little for our issue of having to wait on the long running and blocking call(s) that are made within each iteration (parallel loop thread), since these have to complete before each thread can get to the option of checking if it should stop.

In summary, as the user closes the form, the 20 threads will be signaled to stop via stopExecuting, but they will only stop when they have finished executing their long running function call.

We can't do anything about the fact that the application domain will always stay alive and only be released when all foreground threads have completed. And this means there will be a delay associated with waiting for any blocking calls made within the loop to complete.

Only a true thread abort can interrupt the blocking call, and you must mitigate leaving the system in a unstable/undefined state the best you can in the aborted thread's exception handler which goes without question. Whether that's appropriate is a matter for the programmer to decide, based on what resource handles they chose to maintain and how easy it is to close them in a thread's finally block. You could register with a token to terminate on cancel as a semi workaround i.e.

CancellationTokenSource cts = new CancellationTokenSource();
ParallelOptions po = new ParallelOptions();
po.CancellationToken = cts.Token;
po.MaxDegreeOfParallelism = System.Environment.ProcessorCount;

Parallel.ForEach(iListOfItems, po, (item, loopState) =>
{

    using (cts.Token.Register(Thread.CurrentThread.Abort))
    {
        Try
        {
           Thread.Sleep(120000); // pretend web service call          
        }
        Catch(ThreadAbortException ex)
        {
           // log etc.
        }
        Finally
        {
          // clean up here
        }
    }

});

but this will still result in an exception in the declaring thread.

All things considered, interrupt blocking calls using the parallel.loop constructs could have been a method on the options, avoiding the use of more obscure parts of the library. But why there is no option to cancel and avoid throwing an exception in the declaring method strikes me as a possible oversight.

Yes, require is a Node.JS function and doesn't work in client side scripting without certain requirements. If you're getting this error while writing electronJS code, try the following:

In your BrowserWindow declaration, add the following webPreferences field: i.e, instead of plain mainWindow = new BrowserWindow(), write

mainWindow = new BrowserWindow({
        webPreferences: {
            nodeIntegration: true
        }
    });

You are specifying the -i option:

-i, --include

(HTTP) Include the HTTP-header in the output. The HTTP-header includes things like server-name, date of the document, HTTP-version and more...

Simply remove that option from your command line:

response=$(curl -sb -H "Accept: application/json" "http://host:8080/some/resource")

I think this is the cleanest solution:

class MyTableViewCell: UITableViewCell {
    override func awakeFromNib() {
        super.awakeFromNib()
        layoutMargins = UIEdgeInsetsMake(8, 0, 8, 0)
    }
}

I have discovered that you cannot have conditionals outside of the stored procedure in mysql. This is why the syntax error. As soon as I put the code that I needed between

   BEGIN
   SELECT MONTH(CURDATE()) INTO @curmonth;
   SELECT MONTHNAME(CURDATE()) INTO @curmonthname;
   SELECT DAY(LAST_DAY(CURDATE())) INTO @totaldays;
   SELECT FIRST_DAY(CURDATE()) INTO @checkweekday;
   SELECT DAY(@checkweekday) INTO @checkday;
   SET @daycount = 0;
   SET @workdays = 0;

     WHILE(@daycount < @totaldays) DO
       IF (WEEKDAY(@checkweekday) < 5) THEN
         SET @workdays = @workdays+1;
       END IF;
       SET @daycount = @daycount+1;
       SELECT ADDDATE(@checkweekday, INTERVAL 1 DAY) INTO @checkweekday;
     END WHILE;
   END

Just for others:

If you are not sure how to create a routine in phpmyadmin you can put this in the SQL query

    delimiter ;;
    drop procedure if exists test2;;
    create procedure test2()
    begin
    select ‘Hello World’;
    end
    ;;

Run the query. This will create a stored procedure or stored routine named test2. Now go to the routines tab and edit the stored procedure to be what you want. I also suggest reading http://net.tutsplus.com/tutorials/an-introduction-to-stored-procedures/ if you are beginning with stored procedures.

The first_day function you need is: How to get first day of every corresponding month in mysql?

Showing the Procedure is working Simply add the following line below END WHILE and above END

    SELECT @curmonth,@curmonthname,@totaldays,@daycount,@workdays,@checkweekday,@checkday;

Then use the following code in the SQL Query Window.

    call test2 /* or whatever you changed the name of the stored procedure to */

NOTE: If you use this please keep in mind that this code does not take in to account nationally observed holidays (or any holidays for that matter).

externalIp = os.popen("ipconfig").read().split(":")[15][1:14]

I did it like this in my Jtable its autorefreshing after 300 ms;

DefaultTableModel tableModel = new DefaultTableModel(){
public boolean isCellEditable(int nRow, int nCol) {
                return false;
            }
};
JTable table = new JTable();

Timer t = new Timer(300, new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent e) {
                addColumns();
                remakeData(set);
                table.setModel(model);
            }
        });
        t.start();

private void addColumns() {
        model.setColumnCount(0);
        model.addColumn("NAME");
            model.addColumn("EMAIL");} 

 private void remakeData(CollectionType< Objects > name) {
    model.setRowCount(0);
    for (CollectionType Objects : name){
    String n = Object.getName();
    String e = Object.getEmail();
    model.insertRow(model.getRowCount(),new Object[] { n,e });
    }}

I doubt it will do good with large number of objects like over 500, only other way is to implement TableModelListener in your class, but i did not understand how to use it well. look at http://download.oracle.com/javase/tutorial/uiswing/components/table.html#modelchange

Resurrecting another topic, but this may come in handy for some.

With a little bit of inspiration from https://pyformat.info you can build a method to get a Table of Content [TOC] style printout.

# This is just one way to arrange the data
