w.strip(',.').lower()

Using spacy:

import spacy

nlp = spacy.load('en_core_web_sm')
text = "How are you today? I hope you have a great day"
tokens = nlp(text)
for sent in tokens.sents:
    print(sent.string.strip())

For Linux, try following:

find . -name "YOUR_JAR_FILE.jar" -exec zipgrep "Implementation-Version:" '{}' \;|awk -F ': ' '{print $2}'

I dont know about XamGrid but that's what i'll do with a standard wpf DataGrid:

<DataGrid>
    <DataGrid.Columns>
        <DataGridTemplateColumn>
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding DataContext.MyProperty, RelativeSource={RelativeSource AncestorType=MyUserControl}}"/>
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
            <DataGridTemplateColumn.CellEditingTemplate>
                <DataTemplate>
                    <TextBox Text="{Binding DataContext.MyProperty, RelativeSource={RelativeSource AncestorType=MyUserControl}}"/>
                </DataTemplate>
            </DataGridTemplateColumn.CellEditingTemplate>
        </DataGridTemplateColumn>
    </DataGrid.Columns>
</DataGrid>

Since the TextBlock and the TextBox specified in the cell templates will be part of the visual tree, you can walk up and find whatever control you need.

You can use upstream headers (named starting with $http_) and additional custom headers. For example:

add_header X-Upstream-01 $http_x_upstream_01;
add_header X-Hdr-01  txt01;

next, go to console and make request with user's header:

curl -H "X-Upstream-01: HEADER1" -I http://localhost:11443/

the response contains X-Hdr-01, seted by server and X-Upstream-01, seted by client:

HTTP/1.1 200 OK
Server: nginx/1.8.0
Date: Mon, 30 Nov 2015 23:54:30 GMT
Content-Type: text/html;charset=UTF-8
Connection: keep-alive
X-Hdr-01: txt01
X-Upstream-01: HEADER1

In case you are appending to the DOM, make sure the content is compatible:

modal.find ('div.modal-body').append (content) // check content

Back with .Net 1.1 obfuscation was essential: decompiling code was easy, and you could go from assembly, to IL, to C# code and have it compiled again with very little effort.

Now with .Net 3.5 I'm not at all sure. Try decompiling a 3.5 assembly; what you get is a long long way from compiling.

Add the optimisations from 3.5 (far better than 1.1) and the way anonymous types, delegates and so on are handled by reflection (they are a nightmare to recompile). Add lambda expressions, compiler 'magic' like Linq-syntax and var, and C#2 functions like yield (which results in new classes with unreadable names). Your decompiled code ends up a long long way from compilable.

A professional team with lots of time could still reverse engineer it back again, but then the same is true of any obfuscated code. What code they got out of that would be unmaintainable and highly likely to be very buggy.

I would recommend key-signing your assemblies (meaning if hackers can recompile one they have to recompile all) but I don't think obfuscation's worth it.

Pragma directives specify operating system or machine specific (x86 or x64 etc) compiler options. There are several options available. Details can be found in https://msdn.microsoft.com/en-us/library/d9x1s805.aspx

#pragma comment( comment-type [,"commentstring"] ) has this format.

Refer https://msdn.microsoft.com/en-us/library/7f0aews7.aspx for details about different comment-type.

#pragma comment(lib, "kernel32") #pragma comment(lib, "user32")

The above lines of code includes the library names (or path) that need to be searched by the linker. These details are included as part of the library-search record in the object file.

So, in this case kernel.lib and user32.lib are searched by the linker and included in the final executable.

Use html_entity_decode() and htmlentities().

$html = html_entity_decode(htmlentities($html, ENT_QUOTES, 'UTF-8'), ENT_QUOTES , 'ISO-8859-1');

htmlentities() formats your input into UTF8 and html_entity_decode() formats it back to ISO-8859-1.

You can use ScrimInsetFrameLayout

https://github.com/google/iosched/blob/master/android/src/main/java/com/google/samples/apps/iosched/ui/widget/ScrimInsetsFrameLayout.java

android:fitsSystemWindows="true" should set on scrim layout!

Use FROM_UNIXTIME():

SELECT
  FROM_UNIXTIME(timestamp) 
FROM 
  your_table;

See also: MySQL documentation on FROM_UNIXTIME().

It seems like You haven't set the Mysql server path, Set Environment Variable For MySql Server. Then restart the command prompt and enter mysql -u root-p then it asks for a password enter it. Thank you. Happy learning!

You can use a bind variable at the SQLPlus level to do this. Of course you have little control over the formatting of the output.

VAR x REFCURSOR;
EXEC GetGrantListByPI(args, :x);
PRINT x;

You could use x ** (1. / 3) to compute the (floating-point) cube root of x.

The slight subtlety here is that this works differently for negative numbers in Python 2 and 3. The following code, however, handles that:

def is_perfect_cube(x):
    x = abs(x)
    return int(round(x ** (1. / 3))) ** 3 == x

print(is_perfect_cube(63))
print(is_perfect_cube(64))
print(is_perfect_cube(65))
print(is_perfect_cube(-63))
print(is_perfect_cube(-64))
print(is_perfect_cube(-65))
print(is_perfect_cube(2146689000)) # no other currently posted solution
                                   # handles this correctly

This takes the cube root of x, rounds it to the nearest integer, raises to the third power, and finally checks whether the result equals x.

The reason to take the absolute value is to make the code work correctly for negative numbers across Python versions (Python 2 and 3 treat raising negative numbers to fractional powers differently).

including above solution if still facing issue try as below, Considerign the case where escape is not supported for TS.

blob = new Blob(["\ufeff", csv_content]); // this will make symbols to appears in excel 

for csv_content you can try like below.

function b64DecodeUnicode(str: any) {        
        return decodeURIComponent(atob(str).split('').map((c: any) => {
            return '%' + ('00' + c.charCodeAt(0).toString(16)).slice(-2);
        }).join(''));
    }

In case, you want to keep old field (For ex: name). The query will be:

INSERT INTO table (id, name, age) VALUES(1, "A", 19) ON DUPLICATE KEY UPDATE    
name=name, age=19;

This was my implementation. Essentially, add this before any other scripts on the page. i.e. in your master for a global solution for Internet Explorer 8. I also added in the trim function which seems to be used in allot of frameworks.

<!--[if lte IE 8]>
<script>
    if (!Array.prototype.indexOf) {
        Array.prototype.indexOf = function(obj, start) {
            for (var i = (start || 0), j = this.length; i < j; i++) {
                if (this[i] === obj) {
                    return i;
                }
            }
            return -1;
        };
    }

    if(typeof String.prototype.trim !== 'function') {
        String.prototype.trim = function() {
            return this.replace(/^\s+|\s+$/g, '');
        };
    };

Most of answers talking about scenario catch-log-rethrow.

Instead of writing it in your code consider to use AOP, in particular Postsharp.Diagnostic.Toolkit with OnExceptionOptions IncludeParameterValue and IncludeThisArgument

Check if your current running application is still accessing your mysql and has consumed all the DB connections.

So if you try to access mysql from workbench , you will get "too many connections" error.

stop your current running web application which is holding all those db connections and then your issue will be solved.

The proper interval to get one second is 1000. The Interval property is the time between ticks in milliseconds:

MSDN: Timer.Interval Property

So, it's not the interval that you set that is wrong. Check the rest of your code for something like changing the interval of the timer, or binding the Tick event multiple times.

I tried all the above answers, none of them worked, in my case even docker container ls doesn't show any container running. It looks like the problem is due to the fact that the docker proxy is still using ports although there are no containers running. In my case I was using ubuntu. Here's what I tried and got the problem solved, just run the following two commands:

sudo service docker stop
sudo rm -f /var/lib/docker/network/files/local-kv.db

Try this:

location / {
    root /path/to/root;
    expires 30d;
    access_log off;
}

location ~* ^.*\.php$ {
    if (!-f $request_filename) {
        return 404;
    }
    proxy_set_header X-Real-IP  $remote_addr;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://127.0.0.1:8080;
}

Hopefully it works. Regular expressions have higher priority than plain strings, so all requests ending in .php should be forwared to Apache if only a corresponding .php file exists. Rest will be handled as static files. The actual algorithm of evaluating location is here.

Use the Figure.savefig() method, like so:

ax = s.hist()  # s is an instance of Series
fig = ax.get_figure()
fig.savefig('/path/to/figure.pdf')

It doesn't have to end in pdf, there are many options. Check out the documentation.

Alternatively, you can use the pyplot interface and just call the savefig as a function to save the most recently created figure:

import matplotlib.pyplot as plt
s.hist()
plt.savefig('path/to/figure.pdf')  # saves the current figure

If you load you table file with dtype=str
or convert column type to string df['a'] = df['a'].astype(str)
then you can use such approach:

df['a']= 'col' + df['a'].str[:]

This approach allows prepend, append, and subset string of df.
Works on Pandas v0.23.4, v0.24.1. Don't know about earlier versions.

SOAP web service always make a POST operation whereas using REST you can choose specific HTTP methods like GET, POST, PUT, and DELETE.

Example: to get an item using SOAP you should create a request XML, but in the case of REST you can just specify the item id in the URL itself.

Yeah, it's typically because it starts out as 'where 1 = 0', to force the statement to fail.

It's a more naive way of wrapping it up in a transaction and not committing it at the end, to test your query. (This is the preferred method).

Well if you are doing this in Asp.Net or have access to HttpContext.Current.Request I'd say these are easier and more general ways of getting them:

var scheme = Request.Url.Scheme; // will get http, https, etc.
var host = Request.Url.Host; // will get www.mywebsite.com
var port = Request.Url.Port; // will get the port
var path = Request.Url.AbsolutePath; // should get the /pages/page1.aspx part, can't remember if it only get pages/page1.aspx

I hope this helps. :)

One-liner to read a fixed amount of numbers into a vector (C++11):

#include <algorithm>
#include <iterator>
#include <iostream>
#include <vector>
#include <cstddef>

int main()
{
    const std::size_t LIMIT{5};
    std::vector<int> collection;

    std::generate_n(std::back_inserter(collection), LIMIT,
        []()
        {
            return *(std::istream_iterator<int>(std::cin));
        }
    );

    return 0;
}

I'd use RestSharp - https://github.com/restsharp/RestSharp

Create class to deserialize to:

public class MyObject {
    public string Id { get; set; }
    public string Text { get; set; }
    ...
}

And the code to get that object:

RestClient client = new RestClient("http://whatever.com");
RestRequest request = new RestRequest("path/to/object");
request.AddParameter("id", "123");

// The above code will make a request URL of 
// "http://whatever.com/path/to/object?id=123"
// You can pick and choose what you need

var response = client.Execute<MyObject>(request);

MyObject obj = response.Data;

Check out http://restsharp.org/ to get started.

This has been already answered but I tried a different way to make it simpler.

The idea is using putting an ImageButton on the right of EditText and having negative margin to it so that the EditText flows into the ImageButton making it look like the Button is in the EditText.

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">
        <EditText
            android:id="@+id/editText"
            android:layout_weight="1"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:hint="Enter Pin"
            android:singleLine="true"
            android:textSize="25sp"
            android:paddingRight="60dp"
            />
        <ImageButton
            android:id="@+id/pastePin"
            android:layout_marginLeft="-60dp"
            style="?android:buttonBarButtonStyle"
            android:paddingBottom="5dp"
            android:src="@drawable/ic_action_paste"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />
    </LinearLayout>

Also, as shown above, you can use a paddingRight of similar width in the EditText if you don't want the text in it to be flown over the ImageButton.

I guessed margin size with the help of android-studio's layout designer and it looks similar across all screen sizes. Or else you can calculate the width of the ImageButton and set the margin programatically.

It’s because you tried to update a table without a WHERE that uses a KEY column.

The quick fix is to add SET SQL_SAFE_UPDATES=0; before your query :

SET SQL_SAFE_UPDATES=0; 

Or

close the safe update mode. Edit -> Preferences -> SQL Editor -> SQL Editor remove Forbid UPDATE and DELETE statements without a WHERE clause (safe updates) .

BTW you can use TRUNCATE TABLE tablename; to delete all the records .

You can comma-separate shadows:

box-shadow: inset 0 2px 0px #dcffa6, 0 2px 5px #000;

If you want to use a multiline EditText with imeOptions, try:

android:inputType="textImeMultiLine"

Yes you can pass the model that you have shown using

return RedirectToAction("GetStudent", "Student", student1 );

assuming student1 is an instance of Student

which will generate the following url (assuming your using the default routes and the value of student1 are ID=4 and Name="Amit")

.../Student/GetStudent/4?Name=Amit

Internally the RedirectToAction() method builds a RouteValueDictionary by using the .ToString() value of each property in the model. However, binding will only work if all the properties in the model are simple properties and it fails if any properties are complex objects or collections because the method does not use recursion. If for example, Student contained a property List<string> Subjects, then that property would result in a query string value of

....&Subjects=System.Collections.Generic.List'1[System.String]

and binding would fail and that property would be null

I use this code and works just fine:

input[type="checkbox"], 
input[type="radio"],
input.radio,
input.checkbox {
    vertical-align:text-top;
    width:13px;
    height:13px;
    padding:0;
    margin:0;
    position:relative;
    overflow:hidden;
    top:2px;
}

You may want to readjust top value (depends on your line-height). If you don't want IE6 compatibility, you just need to put this code into your page. Otherwise, you will must add extra class to your inputs (you can use jQuery - or any other library - for that tho ;) )

You can use the JSON.parse() for that.

See docs at MDN

Example:

var myObj = JSON.parse('{"p": 5}');
console.log(myObj);

TextWatcher didn't work for me as it kept firing for every EditText and messing up each others values.

Here is my solution:

public class ConsultantTSView extends Activity {
    .....

    //Submit is called when I push submit button.
    //I wanted to retrieve all EditText(tsHours) values in my HoursList

    public void submit(View view){

        ListView TSDateListView = (ListView) findViewById(R.id.hoursList);
        String value = ((EditText) TSDateListView.getChildAt(0).findViewById(R.id.tsHours)).getText().toString();
    }
}

Hence by using the getChildAt(xx) method you can retrieve any item in the ListView and get the individual item using findViewById. And it will then give the most recent value.

there are some special quotes characters which are not removed by HtmlEncode and will not be displayed in Edge or IE correctly like ” and “ . you can extent replacing these characters with something like below function.

private string RemoveJunkChars(string input)
{
    return HttpUtility.HtmlEncode(input.Replace("”", "\"").Replace("“", "\""));
}

1. Launch Terminal
2. Type -> nano fileName
3. Paste Batch file content and save it
4. Type -> chmod +x fileName
5. It will create exe file now you can double click and it.

File name should in under double quotes. Since i am using Mac->In my case content of batch file is

cd /Users/yourName/Documents/SeleniumServer

java -jar selenium-server-standalone-3.3.1.jar -role hub

It will work for sure

It's not possible with ES3 as the properties have an internal DontEnum attribute which prevents us from enumerating these properties. ES5, on the other hand, provides property descriptors for controlling the enumeration capabilities of properties so user-defined and native properties can use the same interface and enjoy the same capabilities, which includes being able to see non-enumerable properties programmatically.

The getOwnPropertyNames function can be used to enumerate over all properties of the passed in object, including those that are non-enumerable. Then a simple typeof check can be employed to filter out non-functions. Unfortunately, Chrome is the only browser that it works on currently.

?function getAllMethods(object) {
    return Object.getOwnPropertyNames(object).filter(function(property) {
        return typeof object[property] == 'function';
    });
}

console.log(getAllMethods(Math));

logs ["cos", "pow", "log", "tan", "sqrt", "ceil", "asin", "abs", "max", "exp", "atan2", "random", "round", "floor", "acos", "atan", "min", "sin"] in no particular order.

As Nikolai has said you can use the gdb 'set' command to change the value of a variable.

You can also use the 'set' command to change memory locations. eg. Expanding on Nikolai's example:

(gdb) l
6       {
7           int i;
8           struct file *f, *ftmp;
9
(gdb) set variable i = 10
(gdb) p i
$1 = 10

(gdb) p &i
$2 = (int *) 0xbfbb0000
(gdb) set *((int *) 0xbfbb0000) = 20
(gdb) p i
$3 = 20

This should work for any valid pointer, and can be cast to any appropriate data type.

The object doesn't have 30 properties. It has one, which is an array that has 30 elements. You need the number of elements in that array.

Try using the type attribute selector to find buttons (maybe this'll fix it too):

input[type=button]
{
  background-color: #E3E1B8; 
}

input[type=button]:hover
{
  background-color: #46000D
}

as of august 2020 (works for kali linux as well)

sh -c "$(curl -fsSL https://raw.githubusercontent.com/Linuxbrew/install/master/install.sh)"

export brew=/home/linuxbrew/.linuxbrew/bin

test -d ~/.linuxbrew && eval $(~/.linuxbrew/bin/brew shellenv)

test -d /home/linuxbrew/.linuxbrew && eval $(/home/linuxbrew/.linuxbrew/bin/brew shellenv)

test -r ~/.profile && echo "eval \$($(brew --prefix)/bin/brew shellenv)" >>~/.profile     // for ubuntu and debian

In any web application, there will be a web.xml in the WEB-INF/ folder.

If you dont have one in your web app, as it seems to be the case in your folder structure, the default Tomcat web.xml is under TOMCAT_HOME/conf/web.xml

Either way, the relevant lines of the web.xml are

<welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.htm</welcome-file>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>

so any file matching this pattern when found will be shown as the home page.

In Tomcat, a web.xml setting within your web app will override the default, if present.

How do I override the default home page loaded by Tomcat?

"#if one" means that if "#define one" has been written "#if one" is executed otherwise "#ifndef one" is executed.

This is just the C Pre-Processor (CPP) Directive equivalent of the if, then, else branch statements in the C language.

i.e. if {#define one} then printf("one evaluates to a truth "); else printf("one is not defined "); so if there was no #define one statement then the else branch of the statement would be executed.

If you are using Google Chrome on Linux, following command works.

Im having Netty java application and I want to run it as a service with systemd. Unfortunately application stops no matter of what Type I'm using. At the end I've wrapped java start in screen. Here are the config files:

service

[Unit]
Description=Netty service
After=network.target
[Service]
User=user
Type=forking
WorkingDirectory=/home/user/app
ExecStart=/home/user/app/start.sh

Restart=on-failure
RestartSec=5
[Install]
WantedBy=multi-user.target

start

#!/bin/sh
/usr/bin/screen -L -dmS netty_app java -cp app.jar classPath

from that point you can use systemctl [start|stop|status] service.

Note: "schtasks" (see the other, accepted response) has replaced "at". However, "at" may be of use if the situation calls for compatibility with older versions of Windows that don't have schtasks.

                   local computer if this parameter is omitted.
id                 Is an identification number assigned to a scheduled
                   command.
/delete            Cancels a scheduled command. If id is omitted, all the
                   scheduled commands on the computer are canceled.
/yes               Used with cancel all jobs command when no further
                   confirmation is desired.
time               Specifies the time when command is to run.
/interactive       Allows the job to interact with the desktop of the user
                   who is logged on at the time the job runs.
/every:date[,...]  Runs the command on each specified day(s) of the week or
                   month. If date is omitted, the current day of the month
                   is assumed.
/next:date[,...]   Runs the specified command on the next occurrence of the
                   day (for example, next Thursday).  If date is omitted, the
                   current day of the month is assumed.
"command"          Is the Windows NT command, or batch program to be run.

In Python 2, raw_input() returns a string, and input() tries to run the input as a Python expression.

Since getting a string was almost always what you wanted, Python 3 does that with input(). As Sven says, if you ever want the old behaviour, eval(input()) works.

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://www.google.com");
request.Method = "GET";
HttpWebResponse response = (HttpWebResponse)request.GetResponse();

Stream dataStream = response.GetResponseStream();
StreamReader reader = new StreamReader(dataStream);
string strResponse = reader.ReadToEnd();

Try connecting without any password:

mysql -u root

I believe the initial default is no password for the root account (which should obviously be changed as soon as possible).

Adding this in your Application_Start() method of Global.asax file should solve the problem

protected void Application_Start()
{
    GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings
        .ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;
    GlobalConfiguration.Configuration.Formatters
        .Remove(GlobalConfiguration.Configuration.Formatters.XmlFormatter); 
// ...
}

If you are working with EntityFramework, you can disable proxy in your DbContext class constructor. NOTE: this code wll be removed if you update the model

public class MyDbContext : DbContext
{
  public MyDbContext()
  {
    this.Configuration.ProxyCreationEnabled = false;
  }
}

Here's the modern, safe one liner:

java.nio.file.Files.write(java.nio.file.Paths.get("/tmp/output.txt"), "Hello world".getBytes());

nio is a modern IO library shipped by default with the JDK 9+ so no imports or dependencies required.

Perhaps you need to read about interactive usage of Matplotlib. However, if you are going to build an app, you should be using the API and embedding the figures in the windows of your chosen GUI toolkit (see examples/embedding_in_tk.py, etc).

Sorting in an ORDER BY is done by the first column, and then by each additional column in the specified statement.

For instance, consider the following data:

Column1    Column2
=======    =======
1          Smith
2          Jones
1          Anderson
3          Andrews

The query

SELECT Column1, Column2 FROM thedata ORDER BY Column1, Column2

would first sort by all of the values in Column1

and then sort the columns by Column2 to produce this:

Column1    Column2
=======    =======
1          Anderson
1          Smith
2          Jones
3          Andrews

In other words, the data is first sorted in Column1 order, and then each subset (Column1 rows that have 1 as their value) are sorted in order of the second column.

The difference between the two statements you posted is that the rows in the first one would be sorted first by prod_price (price order, from lowest to highest), and then by order of name (meaning that if two items have the same price, the one with the lower alpha value for name would be listed first), while the second would sort in name order only (meaning that prices would appear in order based on the prod_name without regard for price).

this is you need and all people

   string date  = textBox1.Text;

        DateTime date2 = Convert.ToDateTime(date);
        var date3 = date2.Date;
        var D = date3.Day;
      var M =  date3.Month;         
      var y = date3.Year;
      string monthStr = M.ToString("00");
      string date4 = D.ToString() + "/" + monthStr.ToString() + "/" + y.ToString();


      textBox1.Text = date4;

You could convert the dataframe to be a single column with stack (this changes the shape from 5x3 to 15x1) and then take the standard deviation:

df.stack().std()         # pandas default degrees of freedom is one

Alternatively, you can use values to convert from a pandas dataframe to a numpy array before taking the standard deviation:

df.values.std(ddof=1)    # numpy default degrees of freedom is zero

Unlike pandas, numpy will give the standard deviation of the entire array by default, so there is no need to reshape before taking the standard deviation.

A couple of additional notes:

• The numpy approach here is a bit faster than the pandas one, which is generally true when you have the option to accomplish the same thing with either numpy or pandas. The speed difference will depend on the size of your data, but numpy was roughly 10x faster when I tested a few different sized dataframes on my laptop (numpy version 1.15.4 and pandas version 0.23.4).

• The numpy and pandas approaches here will not give exactly the same answers, but will be extremely close (identical at several digits of precision). The discrepancy is due to slight differences in implementation behind the scenes that affect how the floating point values get rounded.

You can get value of id,name or value in this way. class name my_class

 var id_value = $('.my_class').$(this).attr('id'); //get id value
 var name_value = $('.my_class').$(this).attr('name'); //get name value
 var value = $('.my_class').$(this).attr('value'); //get value any input or tag

Here's what I use:

/* Returns a list of files in a directory (except the ones that begin with a dot) */

void GetFilesInDirectory(std::vector<string> &out, const string &directory)
{
#ifdef WINDOWS
    HANDLE dir;
    WIN32_FIND_DATA file_data;

    if ((dir = FindFirstFile((directory + "/*").c_str(), &file_data)) == INVALID_HANDLE_VALUE)
        return; /* No files found */

    do {
        const string file_name = file_data.cFileName;
        const string full_file_name = directory + "/" + file_name;
        const bool is_directory = (file_data.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY) != 0;

        if (file_name[0] == '.')
            continue;

        if (is_directory)
            continue;

        out.push_back(full_file_name);
    } while (FindNextFile(dir, &file_data));

    FindClose(dir);
#else
    DIR *dir;
    class dirent *ent;
    class stat st;

    dir = opendir(directory);
    while ((ent = readdir(dir)) != NULL) {
        const string file_name = ent->d_name;
        const string full_file_name = directory + "/" + file_name;

        if (file_name[0] == '.')
            continue;

        if (stat(full_file_name.c_str(), &st) == -1)
            continue;

        const bool is_directory = (st.st_mode & S_IFDIR) != 0;

        if (is_directory)
            continue;

        out.push_back(full_file_name);
    }
    closedir(dir);
#endif
} // GetFilesInDirectory

I may also add, that nowadays it is possible to decompile Android application online, no software needed!

Here are 2 options for you:

• http://www.decompileandroid.com/
• http://www.javadecompilers.com/apk

sentence.sub! 'Robert', 'Joe'

Won't cause an exception if the replaced word isn't in the sentence (the []= variant will).

How to replace all instances?

The above replaces only the first instance of "Robert".

To replace all instances use gsub/gsub! (ie. "global substitution"):

sentence.gsub! 'Robert', 'Joe'

The above will replace all instances of Robert with Joe.

Integer is only there for the sql standard ie deprecated by Oracle.

You should use Number instead.

Integers get stored as Number anyway by Oracle behind the scenes.

Most commonly when ints are stored for IDs and such they are defined with no params - so in theory you could look at the scale and precision columns of the metadata views to see of no decimal values can be stored - however 99% of the time this will not help.

As was commented above you could look for number(38,0) columns or similar (ie columns with no decimal points allowed) but this will only tell you which columns cannot take decimals, and not what columns were defined so that INTS can be stored.

Suggestion: do a data profile on the number columns. Something like this:

 select max( case when trunc(column_name,0)=column_name then 0 else 1 end ) as has_dec_vals
 from table_name

Here is an example of accessing the ith index of a std::vector using an std::iterator within a loop which does not require incrementing two iterators.

std::vector<std::string> strs = {"sigma" "alpha", "beta", "rho", "nova"};
int nth = 2;
std::vector<std::string>::iterator it;
for(it = strs.begin(); it != strs.end(); it++) {
    int ith = it - strs.begin();
    if(ith == nth) {
        printf("Iterator within  a for-loop: strs[%d] = %s\n", ith, (*it).c_str());
    }
}

Without a for-loop

it = strs.begin() + nth;
printf("Iterator without a for-loop: strs[%d] = %s\n", nth, (*it).c_str());

and using at method:

printf("Using at position: strs[%d] = %s\n", nth, strs.at(nth).c_str());

If you try in Java Swing Application.

1. Go To Firebase Console > Project Overview > Project Settings

2. Then Go to Service Accounts Tab and Then Click on Generate New Private Key.

3. You will get a .json file, place it in a known path

4. Then Go to My Computer Properties, Advanced System Settings, Environment Variables.

5. Create New Path Variable GOOGLE_APPLICATION_CREDENTIALS Value with your path to json file.

NOTE: Despite (or rather, because of) succinctness and apparent elegance, this algorithm is by no means a high-quality one in terms of randomness. Look for e.g. those listed in this answer for better results.

(Originally adapted from a clever idea presented in a comment to another answer.)

var seed = 1;
function random() {
    var x = Math.sin(seed++) * 10000;
    return x - Math.floor(x);
}

You can set seed to be any number, just avoid zero (or any multiple of Math.PI).

The elegance of this solution, in my opinion, comes from the lack of any "magic" numbers (besides 10000, which represents about the minimum amount of digits you must throw away to avoid odd patterns - see results with values 10, 100, 1000). Brevity is also nice.

It's a bit slower than Math.random() (by a factor of 2 or 3), but I believe it's about as fast as any other solution written in JavaScript.

You can use whereIn which accepts an array as second paramter.

DB:table('table')
   ->whereIn('column', [value, value, value])
   ->get()

You can chain where multiple times.

DB:table('table')->where('column', 'operator', 'value')
    ->where('column', 'operator', 'value')
    ->where('column', 'operator', 'value')
    ->get();

This will use AND operator. if you need OR you can use orWhere method.

For advanced where statements

DB::table('table')
    ->where('column', 'operator', 'value')
    ->orWhere(function($query)
    {
        $query->where('column', 'operator', 'value')
            ->where('column', 'operator', 'value');
    })
    ->get();

An API (Application Programming Interface) is the means by which third parties can write code that interfaces with other code. A Web Service is a type of API, one that almost always operates over HTTP (though some, like SOAP, can use alternate transports, like SMTP). The official W3C definition mentions that Web Services don't necessarily use HTTP, but this is almost always the case and is usually assumed unless mentioned otherwise.

For examples of web services specifically, see SOAP, REST, and XML-RPC. For an example of another type of API, one written in C for use on a local machine, see the Linux Kernel API.

As far as the protocol goes, a Web service API almost always uses HTTP (hence the Web part), and definitely involves communication over a network. APIs in general can use any means of communication they wish. The Linux kernel API, for example, uses Interrupts to invoke the system calls that comprise its API for calls from user space.

You need to make TestGetMethod async too and attach await in front of GetIdList(); will unwrap the task to List<int>, So if your helper function is returning Task make sure you have await as you are calling the function async too.

public Task<List<int>> TestGetMethod()
{
    return GetIdList();
}    

async Task<List<int>> GetIdList()
{
    using (HttpClient proxy = new HttpClient())
    {
        string response = await proxy.GetStringAsync("www.test.com");
        List<int> idList = JsonConvert.DeserializeObject<List<int>>();
        return idList;
    }
}

Another option

public async void TestGetMethod(List<int> results)
{
    results = await GetIdList(); // await will unwrap the List<int>
}

Runnable is just an interface, which provides the method run. Threads are implementations and use Runnable to call the method run().

For completeness, also look into the local storage capabilities & sessionStorage of HTML5. These are supported in the latest versions of all modern browsers, and are much easier to use and less fiddly than cookies.

http://www.w3.org/TR/2009/WD-webstorage-20091222/

https://www.w3.org/TR/webstorage/. (second edition)

Here are some sample code for setting and getting the values using sessionStorage and localStorage :

 // HTML5 session Storage
 sessionStorage.setItem("variableName","test");
 sessionStorage.getItem("variableName");


//HTML5 local storage 
localStorage.setItem("variableName","Text");
// Receiving the data:
localStorage.getItem("variableName");

This one seems to be a better fit:

<#if userName?has_content>
... do something
</#if>

Stephan T. Lavavej (stl) from Microsoft did a talk at Going Native about how to use the new C++11 random functions and why not to use rand(). In it, he included a slide that basically solves your question. I've copied the code from that slide below.

You can see his full talk here: http://channel9.msdn.com/Events/GoingNative/2013/rand-Considered-Harmful

#include <random>
#include <iostream>

int main() {
    std::random_device rd;
    std::mt19937 mt(rd());
    std::uniform_real_distribution<double> dist(1.0, 10.0);

    for (int i=0; i<16; ++i)
        std::cout << dist(mt) << "\n";
}

We use random_device once to seed the random number generator named mt. random_device() is slower than mt19937, but it does not need to be seeded because it requests random data from your operating system (which will source from various locations, like RdRand for example).

Looking at this question / answer, it appears that uniform_real_distribution returns a number in the range [a, b), where you want [a, b]. To do that, our uniform_real_distibution should actually look like:

std::uniform_real_distribution<double> dist(1, std::nextafter(10, DBL_MAX));

Here is my solution:

chrome.runtime.onMessage.addListener(function(request, sender) {
        if (request.action == "getSource") {
            this.pageSource = request.source;
            var title = this.pageSource.match(/<title[^>]*>([^<]+)<\/title>/)[1];
            alert(title)
        }
    });

    chrome.tabs.query({ active: true, currentWindow: true }, tabs => {
        chrome.tabs.executeScript(
            tabs[0].id,
            { code: 'var s = document.documentElement.outerHTML; chrome.runtime.sendMessage({action: "getSource", source: s});' }
        );
    });

The C++ semantics of const are very different from Java final. If the designers had used const it would have been unnecessarily confusing.

The fact that const is a reserved word suggests that the designers had ideas for implementing const, but they have since decided against it; see this closed bug. The stated reasons include that adding support for C++ style const would cause compatibility problems.

Try this:

$categories     =   Category::all()->sortByDesc("created_at");

Javascripts .call() and .apply() methods allow you to set the context for a function.

var myfunc = function(){
    alert(this.name);
};

var obj_a = {
    name:  "FOO"
};

var obj_b = {
    name:  "BAR!!"
};

Now you can call:

myfunc.call(obj_a);

Which would alert FOO. The other way around, passing obj_b would alert BAR!!. The difference between .call() and .apply() is that .call() takes a comma separated list if you're passing arguments to your function and .apply() needs an array.

myfunc.call(obj_a, 1, 2, 3);
myfunc.apply(obj_a, [1, 2, 3]);

Therefore, you can easily write a function hook by using the apply() method. For instance, we want to add a feature to jQuerys .css() method. We can store the original function reference, overwrite the function with custom code and call the stored function.

var _css = $.fn.css;
$.fn.css = function(){
   alert('hooked!');
   _css.apply(this, arguments);
};

Since the magic arguments object is an array like object, we can just pass it to apply(). That way we guarantee, that all parameters are passed through to the original function.

Python 3:

user225312's answer is correct:

A. To count number of characters in str object, you can use len() function:

>>> print(len('please anwser my question'))
25

B. To get memory size in bytes allocated to store str object, you can use sys.getsizeof() function

>>> from sys import getsizeof
>>> print(getsizeof('please anwser my question'))
50

Python 2:

It gets complicated for Python 2.

A. The len() function in Python 2 returns count of bytes allocated to store encoded characters in a str object.

Sometimes it will be equal to character count:

>>> print(len('abc'))
3

But sometimes, it won't:

>>> print(len('???'))  # String contains Cyrillic symbols
6

That's because str can use variable-length encoding internally. So, to count characters in str you should know which encoding your str object is using. Then you can convert it to unicode object and get character count:

>>> print(len('???'.decode('utf8'))) #String contains Cyrillic symbols 
3

B. The sys.getsizeof() function does the same thing as in Python 3 - it returns count of bytes allocated to store the whole string object

>>> print(getsizeof('???'))
27
>>> print(getsizeof('???'.decode('utf8')))
32

My favourite was PCRobots back in the 90's - you could write your bot in pretty much any language that could compile a DOS executable. Still runs quite nicely in DOSBox :)

Use Series.view for convert boolean to integers:

df["somecolumn"] = df["somecolumn"].view('i1')

I like this answer https://stackoverflow.com/a/4512317/1818723 just need to apply float point fix

function fpFix(n) {
  return Math.round(n * 100000000) / 100000000;
}

let decimalPart = 2.3 % 1; //0.2999999999999998
let correct = fpFix(decimalPart); //0.3

Complete function handling negative and positive

function getDecimalPart(decNum) {
  return Math.round((decNum % 1) * 100000000) / 100000000;
}

console.log(getDecimalPart(2.3)); // 0.3
console.log(getDecimalPart(-2.3)); // -0.3
console.log(getDecimalPart(2.17247436)); // 0.17247436

P.S. If you are cryptocurrency trading platform developer or banking system developer or any JS developer ;) please apply fpFix everywhere. Thanks!

If you're newing up an element with initializer syntax, you can do something like this:

var row = new HtmlTableRow
{
  Cells =
  {
    new HtmlTableCell
    {
        InnerText = text,
        Attributes = { ["style"] = "min-width: 35px;" }
    },
  }
};

Or if using the CssStyleCollection specifically:

var row = new HtmlTableRow
{
  Cells =
  {
    new HtmlTableCell
    {
        InnerText = text,
        Style = { ["min-width"] = "35px" }
    },
  }
};

This is an old problem with some good information. But what I just found is that using a FQDN turns off the Compat mode in IE 9 - 11. Example. I have the compat problem with
http://lrmstst01:8080/JavaWeb/login.do
but the problems go away with
http://lrmstst01.mydomain.int:8080/JavaWeb/login.do
NB: The .int is part of our internal domain

[xml]$xmlfile = '<xml> <Section name="BackendStatus"> <BEName BE="crust" Status="1" /> <BEName BE="pizza" Status="1" /> <BEName BE="pie" Status="1" /> <BEName BE="bread" Status="1" /> <BEName BE="Kulcha" Status="1" /> <BEName BE="kulfi" Status="1" /> <BEName BE="cheese" Status="1" /> </Section> </xml>'

foreach ($bename in $xmlfile.xml.Section.BEName) {
    if($bename.Status -eq 1){
        #Do something
    }
}

Yes, here's an example:

CREATE TABLE myTable ( col1 int, createdDate datetime DEFAULT(getdate()), updatedDate datetime DEFAULT(getdate()) )

You can INSERT into the table without indicating the createdDate and updatedDate columns:

INSERT INTO myTable (col1) VALUES (1)

Or use the keyword DEFAULT:

INSERT INTO myTable (col1, createdDate, updatedDate) VALUES (1, DEFAULT, DEFAULT)

Then create a trigger for updating the updatedDate column:

CREATE TRIGGER dbo.updateMyTable 
ON dbo.myTable
FOR UPDATE 
AS 
BEGIN 
    IF NOT UPDATE(updatedDate) 
        UPDATE dbo.myTable SET updatedDate=GETDATE() 
        WHERE col1 IN (SELECT col1 FROM inserted) 
END 
GO

Label1.Text = dt.ToString("dd MMM yyyy | hh:mm | ff | zzz | zz | z");

will output:

07 Mai 2009 | 08:16 | 13 | +02:00 | +02 | +2

I'm in Denmark, my Offset from GMT is +2 hours, witch is correct.

if you need to get the CLIENT Offset, I recommend that you check a little trick that I did. The Page is in a Server in UK where GMT is +00:00 and, as you can see you will get your local GMT Offset.

Regarding you comment, I did:

DateTime dt1 = DateTime.Now;
DateTime dt2 = dt1.ToUniversalTime();

Label1.Text = dt1.ToString("dd MMM yyyy | hh:mm | ff | zzz | zz | z");
Label2.Text = dt2.ToString("dd MMM yyyy | hh:mm | FF | ZZZ | ZZ | Z");

and I get this:

07 Mai 2009 | 08:24 | 14 | +02:00 | +02 | +2
07 Mai 2009 | 06:24 | 14 | ZZZ | ZZ | Z 

I get no Exception, just ... it does nothing with capital Z :(

I'm sorry, but am I missing something?

Reading carefully the MSDN on Custom Date and Time Format Strings

there is no support for uppercase 'Z'.

Pragma mark is a way to improve the readability of your code. The pragma comments would appear like tags on the Xcode jumpbar.

//MARK:  <Your comment goes here>

Example: In the code,

//MARK: Properties

// MARK: View Life cycle

//MARK: Helper methods

This is how it would appear in the Xcode jump bar.

Using the getDateInstance of SimpleDateFormat, we can compare only two date object without time. Execute the below code.

public static void main(String[] args) {        
        Date date1  = new Date();
        Date date2  = new Date();
        DateFormat dfg = SimpleDateFormat.getDateInstance(DateFormat.DATE_FIELD);
        String dateDtr1 = dfg.format(date1);
        String dateDtr2 = dfg.format(date2);
        System.out.println(dateDtr1+" : "+dateDtr2);
        System.out.println(dateDtr1.equals(dateDtr2));  

    }

An alternative solution is to simply add a route to your routes.rb

It basically catches the Apple request and renders a 404 back to the client. This way your log files aren't cluttered.

# routes.rb at the near-end
match '/:png', via: :get, controller: 'application', action: 'apple_touch_not_found', png: /apple-touch-icon.*\.png/

then add a method 'apple_touch_not_found' to your application_controller.rb

# application_controller.rb
def apple_touch_not_found
  render  plain: 'apple-touch icons not found', status: 404
end

Using the solution of Slauma, I created some generic functions to help update child objects and collections of child objects.

All my persistent objects implement this interface

/// <summary>
/// Base interface for all persisted entries
/// </summary>
public interface IBase
{
    /// <summary>
    /// The Id
    /// </summary>
    int Id { get; set; }
}

With this I implemented these two functions in my Repository

    /// <summary>
    /// Check if orgEntry is set update it's values, otherwise add it
    /// </summary>
    /// <param name="set">The collection</param>
    /// <param name="entry">The entry</param>
    /// <param name="orgEntry">The original entry found in the database (can be <code>null</code> is this is a new entry)</param>
    /// <returns>The added or updated entry</returns>
    public T AddOrUpdateEntry<T>(DbSet<T> set, T entry, T orgEntry) where T : class, IBase
    {
        if (entry.Id == 0 || orgEntry == null)
        {
            entry.Id = 0;
            return set.Add(entry);
        }
        else
        {
            Context.Entry(orgEntry).CurrentValues.SetValues(entry);
            return orgEntry;
        }
    }

    /// <summary>
    /// check if each entry of the new list was in the orginal list, if found, update it, if not found add it
    /// all entries found in the orignal list that are not in the new list are removed
    /// </summary>
    /// <typeparam name="T">The type of entry</typeparam>
    /// <param name="set">The database set</param>
    /// <param name="newList">The new list</param>
    /// <param name="orgList">The original list</param>
    public void AddOrUpdateCollection<T>(DbSet<T> set, ICollection<T> newList, ICollection<T> orgList) where T : class, IBase
    {
        // attach or update all entries in the new list
        foreach (T entry in newList)
        {
            // Find out if we had the entry already in the list
            var orgEntry = orgList.SingleOrDefault(e => e.Id != 0 && e.Id == entry.Id);

            AddOrUpdateEntry(set, entry, orgEntry);
        }

        // Remove all entries from the original list that are no longer in the new list
        foreach (T orgEntry in orgList.Where(e => e.Id != 0).ToList())
        {
            if (!newList.Any(e => e.Id == orgEntry.Id))
            {
                set.Remove(orgEntry);
            }
        }
    }

To use it i do the following:

var originalParent = _dbContext.ParentItems
    .Where(p => p.Id == parent.Id)
    .Include(p => p.ChildItems)
    .Include(p => p.ChildItems2)
    .SingleOrDefault();

// Add the parent (including collections) to the context or update it's values (except the collections)
originalParent = AddOrUpdateEntry(_dbContext.ParentItems, parent, originalParent);

// Update each collection
AddOrUpdateCollection(_dbContext.ChildItems, parent.ChildItems, orgiginalParent.ChildItems);
AddOrUpdateCollection(_dbContext.ChildItems2, parent.ChildItems2, orgiginalParent.ChildItems2);

Hope this helps

EXTRA: You could also make a seperate DbContextExtentions (or your own context inferface) class:

public static void DbContextExtentions {
    /// <summary>
    /// Check if orgEntry is set update it's values, otherwise add it
    /// </summary>
    /// <param name="_dbContext">The context object</param>
    /// <param name="set">The collection</param>
    /// <param name="entry">The entry</param>
    /// <param name="orgEntry">The original entry found in the database (can be <code>null</code> is this is a new entry)</param>
    /// <returns>The added or updated entry</returns>
    public static T AddOrUpdateEntry<T>(this DbContext _dbContext, DbSet<T> set, T entry, T orgEntry) where T : class, IBase
    {
        if (entry.IsNew || orgEntry == null) // New or not found in context
        {
            entry.Id = 0;
            return set.Add(entry);
        }
        else
        {
            _dbContext.Entry(orgEntry).CurrentValues.SetValues(entry);
            return orgEntry;
        }
    }

    /// <summary>
    /// check if each entry of the new list was in the orginal list, if found, update it, if not found add it
    /// all entries found in the orignal list that are not in the new list are removed
    /// </summary>
    /// <typeparam name="T">The type of entry</typeparam>
    /// <param name="_dbContext">The context object</param>
    /// <param name="set">The database set</param>
    /// <param name="newList">The new list</param>
    /// <param name="orgList">The original list</param>
    public static void AddOrUpdateCollection<T>(this DbContext _dbContext, DbSet<T> set, ICollection<T> newList, ICollection<T> orgList) where T : class, IBase
    {
        // attach or update all entries in the new list
        foreach (T entry in newList)
        {
            // Find out if we had the entry already in the list
            var orgEntry = orgList.SingleOrDefault(e => e.Id != 0 && e.Id == entry.Id);

            AddOrUpdateEntry(_dbContext, set, entry, orgEntry);
        }

        // Remove all entries from the original list that are no longer in the new list
        foreach (T orgEntry in orgList.Where(e => e.Id != 0).ToList())
        {
            if (!newList.Any(e => e.Id == orgEntry.Id))
            {
                set.Remove(orgEntry);
            }
        }
    }
}

and use it like:

var originalParent = _dbContext.ParentItems
    .Where(p => p.Id == parent.Id)
    .Include(p => p.ChildItems)
    .Include(p => p.ChildItems2)
    .SingleOrDefault();

// Add the parent (including collections) to the context or update it's values (except the collections)
originalParent = _dbContext.AddOrUpdateEntry(_dbContext.ParentItems, parent, originalParent);

// Update each collection
_dbContext.AddOrUpdateCollection(_dbContext.ChildItems, parent.ChildItems, orgiginalParent.ChildItems);
_dbContext.AddOrUpdateCollection(_dbContext.ChildItems2, parent.ChildItems2, orgiginalParent.ChildItems2);

Interfaces can also be daisy chained to create yet another interface. This ability to implement multiple Interfaces give the developer the advantage of adding functionality to their classes without having to change current class functionality (SOLID Principles)

O = "Classes should be open for extension but closed for modification"

You need to qualify the a part of the selector too:

.button input, .button a {
    //css stuff here
}

Basically, when you use the comma to create a group of selectors, each individual selector is completely independent. There is no relationship between them.

Your original selector therefore matched "all elements of type 'input' that are descendants of an element with the class name 'button', and all elements of type 'a'".

My suggestion:

$.fn.attrs = function (fnc) {
    var obj = {};
    $.each(this[0].attributes, function() {
        if(this.name == 'value') return; // Avoid someone (optional)
        if(this.specified) obj[this.name] = this.value;
    });
    return obj;
}

var a = $(el).attrs();

See the NSMutableArray method sortUsingFunction:context:

You will need to set up a compare function which takes two objects (of type Person, since you are comparing two Person objects) and a context parameter.

The two objects are just instances of Person. The third object is a string, e.g. @"birthDate".

This function returns an NSComparisonResult: It returns NSOrderedAscending if PersonA.birthDate < PersonB.birthDate. It will return NSOrderedDescending if PersonA.birthDate > PersonB.birthDate. Finally, it will return NSOrderedSame if PersonA.birthDate == PersonB.birthDate.

This is rough pseudocode; you will need to flesh out what it means for one date to be "less", "more" or "equal" to another date (such as comparing seconds-since-epoch etc.):

NSComparisonResult compare(Person *firstPerson, Person *secondPerson, void *context) {
  if ([firstPerson birthDate] < [secondPerson birthDate])
    return NSOrderedAscending;
  else if ([firstPerson birthDate] > [secondPerson birthDate])
    return NSOrderedDescending;
  else 
    return NSOrderedSame;
}

If you want something more compact, you can use ternary operators:

NSComparisonResult compare(Person *firstPerson, Person *secondPerson, void *context) {
  return ([firstPerson birthDate] < [secondPerson birthDate]) ? NSOrderedAscending : ([firstPerson birthDate] > [secondPerson birthDate]) ? NSOrderedDescending : NSOrderedSame;
}

Inlining could perhaps speed this up a little, if you do this a lot.

Use Reflection:

Type type = obj.GetType();
PropertyInfo[] properties = type.GetProperties();

foreach (PropertyInfo property in properties)
{
    Console.WriteLine("Name: " + property.Name + ", Value: " + property.GetValue(obj, null));
}

for Excel - what tools/reference item must be added to gain access to BindingFlags, as there is no "System.Reflection" entry in the list

Edit: You can also specify a BindingFlags value to type.GetProperties():

BindingFlags flags = BindingFlags.Public | BindingFlags.Instance;
PropertyInfo[] properties = type.GetProperties(flags);

That will restrict the returned properties to public instance properties (excluding static properties, protected properties, etc).

You don't need to specify BindingFlags.GetProperty, you use that when calling type.InvokeMember() to get the value of a property.

For completely transparent color, use:

rbga(255,255,255,0)

A little more visible:

rbga(255,255,255,.3)

Just to give an alternative solution, because it isn't mentioned.

It's perfectly fine to use the HTML attribute defer here. So when loading the DOM, a regular <script> will load when the DOM hits the script. But if we use defer, then the DOM and the script will load in parallel. The cool thing is the script gets evaluated in the end - when the DOM has loaded (source).

<script src="{% static "build/react.js" %}" defer></script>

Turning Marc Gravell's answer into an extension method, I made the following.

internal static IEnumerable<Tuple<TLeft, TRight>> LeftJoin<TLeft, TRight, TKey>(
    this IEnumerable<TLeft> left,
    IEnumerable<TRight> right,
    Func<TLeft, TKey> selectKeyLeft,
    Func<TRight, TKey> selectKeyRight,
    TRight defaultRight = default(TRight),
    IEqualityComparer<TKey> cmp = null)
{
    return left.GroupJoin(
            right,
            selectKeyLeft,
            selectKeyRight,
            (x, y) => new Tuple<TLeft, IEnumerable<TRight>>(x, y),
            cmp ?? EqualityComparer<TKey>.Default)
        .SelectMany(
            x => x.Item2.DefaultIfEmpty(defaultRight),
            (x, y) => new Tuple<TLeft, TRight>(x.Item1, y));
}

This should work:

var hv = $('#h_v').val();
alert(hv);

On the anaconda prompt, do a

• python -V or python --version to get the python version.
• conda list anaconda$ to get the Anaconda version.
• conda list to get the Name, Version, Build & Channel details of all the packages installed (in the current environment).
• conda info to get all the current environment details.
• conda info --envs To see a list of all your environments

I want to supplement a way to copy the line to the clipboard and use it on the function.

here is an example that you open the URL in the browser

let g:chrome_exe = 'C:/.../Google/Chrome/Application/chrome.exe'
function OpenURL()
    " copy the line and put it in the register *
    normal "*yy
    :execute "silent !start ".g:chrome_exe." ".getreg("*")
endfunction

map ,url :call OpenURL()<CR>

To check for an exact match you would use num == line. But line has an end-of-line character \n or \r\n which will not be in num since raw_input strips the trailing newline. So it may be convenient to remove all whitespace at the end of line with

line = line.rstrip()

with open("file.txt") as search:
    for line in search:
        line = line.rstrip()  # remove '\n' at end of line
        if num == line:
            print(line )

For a []string, you can use strings.Join():

s := []string{"foo", "bar", "baz"}
fmt.Println(strings.Join(s, ", "))
// output: foo, bar, baz

This is just a guess, but I think your editor actually matches every single digit — 1 2 3 — but only odd matches are highlighted, to distinguish it from the case when the whole 123 string is matched.

Most regex consoles highlight contiguous matches with different colors, but due to the plugin settings, terminal limitations or for some other reason, only every other group might be highlighted in your case.

Something to keep in mind is that this error isn't only due to self signed certs. The new Entrust CA certs fail with the same error, and the right thing to do is to update the server with the appropriate root certs, not to disable this important security feature.

If you used a raw socket (SOCK_RAW) and re-implemented TCP in userland, I think the answer is limited in this case only by the number of (local address, source port, destination address, destination port) tuples (~2^64 per local address).

It would of course take a lot of memory to keep the state of all those connections, and I think you would have to set up some iptables rules to keep the kernel TCP stack from getting upset &/or responding on your behalf.

Try cleaning your hosts file.

I spent about half a day on this, and none of these answers worked for me. I finally found the solution hinted at on OTN (the last place I look when I run into Oracle issues), and someone mentioned looking at the hosts file. I had recently modified the hosts file because this particular machine didn't have access to DNS.

I had a line for this host:

123.123.123.123     fully.qualified.domain.name.com     hostname

Commenting out the line above allowed me to install the Oracle client.

Just a note that as of Ruby 2.0 there is no need to add # encoding: utf-8. UTF-8 is automatically detected.

Use immutableJS

import { fromJS } from 'immutable';

// An object we want to clone
let objA = { 
   a: { deep: 'value1', moreDeep: {key: 'value2'} } 
};

let immB = fromJS(objA); // Create immutable Map
let objB = immB.toJS(); // Convert to plain JS object

console.log(objA); // Object { a: { deep: 'value1', moreDeep: {key: 'value2'} } }
console.log(objB); // Object { a: { deep: 'value1', moreDeep: {key: 'value2'} } }

// objA and objB are equalent, but now they and their inner objects are undependent
console.log(objA === objB); // false
console.log(objA.a === objB.a); // false
console.log(objA.moreDeep === objB.moreDeep); // false

Or lodash/merge

import merge from 'lodash/merge'

var objA = {
    a: [{ 'b': 2 }, { 'd': 4 }]
};
// New deeply cloned object:
merge({}, objA ); 

// We can also create new object from several objects by deep merge:
var objB = {
    a: [{ 'c': 3 }, { 'e': 5 }]
};
merge({}, objA , objB ); // Object { a: [{ 'b': 2, 'c': 3 }, { 'd': 4, 'e': 5 }] }

urlretrieve and requests.get are simple, however the reality not. I have fetched data for couple sites, including text and images, the above two probably solve most of the tasks. but for a more universal solution I suggest the use of urlopen. As it is included in Python 3 standard library, your code could run on any machine that run Python 3 without pre-installing site-package

import urllib.request
url_request = urllib.request.Request(url, headers=headers)
url_connect = urllib.request.urlopen(url_request)

#remember to open file in bytes mode
with open(filename, 'wb') as f:
    while True:
        buffer = url_connect.read(buffer_size)
        if not buffer: break

        #an integer value of size of written data
        data_wrote = f.write(buffer)

#you could probably use with-open-as manner
url_connect.close()

This answer provides a solution to HTTP 403 Forbidden when downloading file over http using Python. I have tried only requests and urllib modules, the other module may provide something better, but this is the one I used to solve most of the problems.

"-TotalCount" in this instance responds exactly like "-head". You have to use -TotalCount or -head to run the command like that. But -TotalCount is misleading - it does not work in ACTUALLY giving you ANY counts...

gc -TotalCount 25 C:\scripts\logs\robocopy_report.txt

The above script, tested in PS 5.1 is the SAME response as below...

gc -head 25 C:\scripts\logs\robocopy_report.txt

So then just use '-head 25" already!

When you reference Range like that it's called an unqualified reference because you don't specifically say which sheet the range is on. Unqualified references are handled by the "_Global" object that determines which object you're referring to and that depends on where your code is.

If you're in a standard module, unqualified Range will refer to Activesheet. If you're in a sheet's class module, unqualified Range will refer to that sheet.

inputTemplateContent is a variable that contains a reference to a range, probably a named range. If you look at the RefersTo property of that named range, it likely points to a sheet other than the Activesheet at the time the code executes.

The best way to fix this is to avoid unqualified Range references by specifying the sheet. Like

With ThisWorkbook.Worksheets("Template")
    .Range(inputTemplateHeader).Value = NO_ENTRY
    .Range(inputTemplateContent).Value = NO_ENTRY
End With

Adjust the workbook and worksheet references to fit your particular situation.

This works for me:

Open the command palette (Ctrl + Shift + P) and choose "Python: Select Interpreter".

Doing this, you set the Python interpreter in Visual Studio Code.

This will help you to change the name for "no file choose to Select profile picture"

<input type='file'id="files" class="hidden"/>  
<label for="files">Select profile picture</label>

you can do like this:

if("merchant_id" in thisSession){ /** will return true if exist */
 console.log('Exist!');
}

or

if(thisSession["merchant_id"]){ /** will return its value if exist */
 console.log('Exist!');
}

If feed isn't well-formed XML, you're supposed to reject it, no exceptions. You're entitled to call feed creator a bozo.

Otherwise you're paving way to mess that HTML ended up in.

Setting html { height: 100%} can wreak havoc with IE. Here's an example (png). But you know what works great? Just set your background on the <html> tag.

html {
  -moz-linear-gradient(top, #fff, #000);
  /* etc. */
}

Background extends to the bottom and no weird scrolling behavior occurs. You can skip all of the other fixes. And this is broadly supported. I haven't found a browser that doesn't let you apply a background to the html tag. It's perfectly valid CSS and has been for a while. :)

ORA-01422: exact fetch returns more than requested number of rows

if you don't specify the exact record by using where condition, you will get the above exception

DECLARE
     ID NUMBER;
BEGIN
     select eid into id from employee where salary=26500;
     DBMS_OUTPUT.PUT_LINE(ID);
END;

string.split("=", 2);

As String.split(java.lang.String regex, int limit) explains:

The array returned by this method contains each substring of this string that is terminated by another substring that matches the given expression or is terminated by the end of the string. The substrings in the array are in the order in which they occur in this string. If the expression does not match any part of the input then the resulting array has just one element, namely this string.

The limit parameter controls the number of times the pattern is applied and therefore affects the length of the resulting array. If the limit n is greater than zero then the pattern will be applied at most n - 1 times, the array's length will be no greater than n, and the array's last entry will contain all input beyond the last matched delimiter.

The string boo:and:foo, for example, yields the following results with these parameters:

Regex Limit    Result
:     2        { "boo", "and:foo" }
:     5        { "boo", "and", "foo" }
:    -2        { "boo", "and", "foo" }
o     5        { "b", "", ":and:f", "", "" }
o    -2        { "b", "", ":and:f", "", "" }
o     0        { "b", "", ":and:f" }

I have open-sourced a UIButton subclass, STAButton, to fill in this gaping functionality hole. Available under the MIT license. Works for iOS 7+ (I have not tested with older iOS versions).

I faced an another use case where I got the similar error. When At first I got the error, I panicked, and removed /data/data/{package.name} After that I tried, and my problem was still present. Then I tried uninstall, it failed.

I then removed the apk file present in /system/app (required root access), and tried uninstall and it was successfull.

After that I tried re-installing the apk, it worked.

JavaScript Strings are stored in UTF-16. To get UTF-8, you'll have to convert the String yourself.

One way is to mix encodeURIComponent(), which will output UTF-8 bytes URL-encoded, with unescape, as mentioned on ecmanaut.

var utf8 = unescape(encodeURIComponent(str));

var arr = [];
for (var i = 0; i < utf8.length; i++) {
    arr.push(utf8.charCodeAt(i));
}

You are inside vim. To save changes and quit, type:

<esc> :wq <enter>

That means:

• Press Escape. This should make sure you are in command mode
• type in :wq
• Press Return

An alternative that stdcall in the comments mentions is:

• Press Escape
• Press shift+Z shift+Z (capital Z twice).

To the great answers that already included here I want to add something that missing in my perspective - an illustration.

As you already JVM divides the allocated memory to a Java program into two parts. one is stack and another one is heap. Stack is used for execution purpose and heap is used for storage purpose. In that heap memory, JVM allocates some memory specially meant for string literals. This part of the heap memory is called string constants pool.

So for example, if you init the following objects:

String s1 = "abc"; 
String s2 = "123";
String obj1 = new String("abc");
String obj2 = new String("def");
String obj3 = new String("456);

String literals s1 and s2 will go to string constant pool, objects obj1, obj2, obj3 to the heap. All of them, will be referenced from the Stack.

Also, please note that "abc" will appear in heap and in string constant pool. Why is String s1 = "abc" and String obj1 = new String("abc") will be created this way? It's because String obj1 = new String("abc") explicitly creates a new and referentially distinct instance of a String object and String s1 = "abc" may reuse an instance from the string constant pool if one is available.

Text Shadow Generator

There are lots of great answers here. It would appear the text-shadow is probably the most reliable way to do this. I won't go into detail about how to do this with text-shadow since others have already done that, but the basic idea is that you create multiple text shadows around the text element. The larger the text outline, the more text shadows you need.

All of the answers submitted (as of this posting) provide static solutions for the text-shadow. I have taken a different approach and have written this JSFiddle that accepts outline color, blur, and width values as inputs and generates the appropriate text-shadow property for your element. Just fill in the blanks, check the preview, and click to copy the css and paste it into your stylesheet.

Needless Appendix

Apparently, answers that include a link to a JSFiddle cannot be posted unless they also contain code. You can completely ignore this appendix if you want to. This is the JavaScript from my fiddle that generates the text-shadow property. Please note that you do not need to implement this code in your own works:

function computeStyle() {
    var width = document.querySelector('#outline-width').value;
  width = (width === '') ? 0 : Number.parseFloat(width);
  var blur = document.querySelector('#outline-blur').value;
  blur = (blur === '') ? 0 : Number.parseFloat(blur);
  var color = document.querySelector('#outline-color').value;
  if (width < 1 || color === '') {
    document.querySelector('.css-property').innerText = '';
    return;
  }
    var style = 'text-shadow: ';
  var indent = false;
    for (var i = -1 * width; i <= width; ++i) {
    for (var j = -1 * width; j <= width; ++j) {
        if (! (i === 0 && j === 0 && blur === 0)) {
        var indentation = (indent) ? '\u00a0\u00a0\u00a0\u00a0' : '';
            style += indentation + i + "px " + j + "px " + blur + "px " + color + ',\n';
        indent = true;
      }
    }
  }
  style = style.substring(0, style.length - 2) + '\n;';
  document.querySelector('.css-property').innerText = style;

  var exampleBackground = document.querySelector('#example-bg');
  var exampleText = document.querySelector('#example-text');
  exampleBackground.style.backgroundColor = getOppositeColor(color);
  exampleText.style.color = getOppositeColor(color);
  var textShadow = style.replace(/text-shadow: /, '').replace(/\n/g, '').replace(/.$/, '').replace(/\u00a0\u00a0\u00a0\u00a0/g, '');
  exampleText.style.textShadow = textShadow;
}

I would like to add that if you get the MoreLinq extension there is now support for both homogenous and heterogeneous left joins now

http://morelinq.github.io/2.8/ref/api/html/Overload_MoreLinq_MoreEnumerable_LeftJoin.htm

example:

//Pretend a ClientCompany object and an Employee object both have a ClientCompanyID key on them

return DataContext.ClientCompany
    .LeftJoin(DataContext.Employees,                         //Table being joined
        company => company.ClientCompanyID,                  //First key
        employee => employee.ClientCompanyID,                //Second Key
        company => new {company, employee = (Employee)null}, //Result selector when there isn't a match
        (company, employee) => new { company, employee });   //Result selector when there is a match

EDIT:

In retrospect this may work, but it converts the IQueryable to an IEnumerable as morelinq does not convert the query to SQL.

You can instead use a GroupJoin as described here: https://stackoverflow.com/a/24273804/4251433

This will ensure that it stays as an IQueryable in case you need to do further logical operations on it later.

In addition to all the previous answers, I would like to tell about the different behavior of gather() and wait() in case they are cancelled.

Gather cancellation

If gather() is cancelled, all submitted awaitables (that have not completed yet) are also cancelled.

Wait cancellation

If the wait() task is cancelled, it simply throws an CancelledError and the waited tasks remain intact.

Simple example:

import asyncio


async def task(arg):
    await asyncio.sleep(5)
    return arg


async def cancel_waiting_task(work_task, waiting_task):
    await asyncio.sleep(2)
    waiting_task.cancel()
    try:
        await waiting_task
        print("Waiting done")
    except asyncio.CancelledError:
        print("Waiting task cancelled")

    try:
        res = await work_task
        print(f"Work result: {res}")
    except asyncio.CancelledError:
        print("Work task cancelled")


async def main():
    work_task = asyncio.create_task(task("done"))
    waiting = asyncio.create_task(asyncio.wait({work_task}))
    await cancel_waiting_task(work_task, waiting)

    work_task = asyncio.create_task(task("done"))
    waiting = asyncio.gather(work_task)
    await cancel_waiting_task(work_task, waiting)


asyncio.run(main())

Output:

asyncio.wait()
Waiting task cancelled
Work result: done
----------------
asyncio.gather()
Waiting task cancelled
Work task cancelled

Sometimes it becomes necessary to combine wait() and gather() functionality. For example, we want to wait for the completion of at least one task and cancel the rest pending tasks after that, and if the waiting itself was canceled, then also cancel all pending tasks.

As real examples, let's say we have a disconnect event and a work task. And we want to wait for the results of the work task, but if the connection was lost, then cancel it. Or we will make several parallel requests, but upon completion of at least one response, cancel all others.

It could be done this way:

import asyncio
from typing import Optional, Tuple, Set


async def wait_any(
        tasks: Set[asyncio.Future], *, timeout: Optional[int] = None,
) -> Tuple[Set[asyncio.Future], Set[asyncio.Future]]:
    tasks_to_cancel: Set[asyncio.Future] = set()
    try:
        done, tasks_to_cancel = await asyncio.wait(
            tasks, timeout=timeout, return_when=asyncio.FIRST_COMPLETED
        )
        return done, tasks_to_cancel
    except asyncio.CancelledError:
        tasks_to_cancel = tasks
        raise
    finally:
        for task in tasks_to_cancel:
            task.cancel()


async def task():
    await asyncio.sleep(5)


async def cancel_waiting_task(work_task, waiting_task):
    await asyncio.sleep(2)
    waiting_task.cancel()
    try:
        await waiting_task
        print("Waiting done")
    except asyncio.CancelledError:
        print("Waiting task cancelled")

    try:
        res = await work_task
        print(f"Work result: {res}")
    except asyncio.CancelledError:
        print("Work task cancelled")


async def check_tasks(waiting_task, working_task, waiting_conn_lost_task):
    try:
        await waiting_task
        print("waiting is done")
    except asyncio.CancelledError:
        print("waiting is cancelled")

    try:
        await waiting_conn_lost_task
        print("connection is lost")
    except asyncio.CancelledError:
        print("waiting connection lost is cancelled")

    try:
        await working_task
        print("work is done")
    except asyncio.CancelledError:
        print("work is cancelled")


async def work_done_case():
    working_task = asyncio.create_task(task())
    connection_lost_event = asyncio.Event()
    waiting_conn_lost_task = asyncio.create_task(connection_lost_event.wait())
    waiting_task = asyncio.create_task(wait_any({working_task, waiting_conn_lost_task}))
    await check_tasks(waiting_task, working_task, waiting_conn_lost_task)


async def conn_lost_case():
    working_task = asyncio.create_task(task())
    connection_lost_event = asyncio.Event()
    waiting_conn_lost_task = asyncio.create_task(connection_lost_event.wait())
    waiting_task = asyncio.create_task(wait_any({working_task, waiting_conn_lost_task}))
    await asyncio.sleep(2)
    connection_lost_event.set()  # <---
    await check_tasks(waiting_task, working_task, waiting_conn_lost_task)


async def cancel_waiting_case():
    working_task = asyncio.create_task(task())
    connection_lost_event = asyncio.Event()
    waiting_conn_lost_task = asyncio.create_task(connection_lost_event.wait())
    waiting_task = asyncio.create_task(wait_any({working_task, waiting_conn_lost_task}))
    await asyncio.sleep(2)
    waiting_task.cancel()  # <---
    await check_tasks(waiting_task, working_task, waiting_conn_lost_task)


async def main():
    print("Work done")
    print("-------------------")
    await work_done_case()
    print("\nConnection lost")
    print("-------------------")
    await conn_lost_case()
    print("\nCancel waiting")
    print("-------------------")
    await cancel_waiting_case()


asyncio.run(main())

Output:

Work done
-------------------
waiting is done
waiting connection lost is cancelled
work is done

Connection lost
-------------------
waiting is done
connection is lost
work is cancelled

Cancel waiting
-------------------
waiting is cancelled
waiting connection lost is cancelled
work is cancelled

You could also use the render file:

render file: "#{Rails.root}/public/404.html", layout: false, status: 404

Where you can choose to use the layout or not.

Another option is to use the Exceptions to control it:

raise ActiveRecord::RecordNotFound, "Record not found."

I'm not sure it's possible "out of the box". And, unfortunately, I don't know an appropriate plugin either. To solve the problem you suggested you could use regular expressions.

1. Cmd + F (Find)
2. Regexp: [^ ]+ (or \d+, or whatever you prefer)
3. Option + F (Find All)
4. Edit it

Assuming you are a PyCharm User, its pretty easy to install Flask This will help users without shell pip access also.

• Open Settings(Ctrl+Alt+s) >>
• Goto Project Interpreter>>
• Double click pip>> Search for flask
• Select and click Install Package ( Check Install to site users if intending to use Flask for this project alone Done!!!

Cases in which flask is not shown in pip: Open Manage Repository>> Add(+) >> Add this following url

https://www.palletsprojects.com/p/flask/

Now back to pip, it will show related packages of flask,

• select flask>>
• install package>>

You can either use the Erase or ReDim statements to clear the array. Examples of each are shown in the MSDN documentation. For example:

Dim threeDimArray(9, 9, 9), twoDimArray(9, 9) As Integer
Erase threeDimArray, twoDimArray
ReDim threeDimArray(4, 4, 9)

To remove a collection, you iterate over its items and use the Remove method:

For i = 1 to MyCollection.Count
  MyCollection.Remove 1 ' Remove first item
Next i

If you're using a table view to display Settings and other options (like the built-in Settings app does), then you can set your Table View Content to Static Cells under the Attributes Inspector. Also, to do this, you must embedded your Table View in a UITableViewController instance.

My solution on Windows was to either run console window as Administrator or change the environment variable MAVEN_OPTS to use a hardcoded path to trust.jks (e.g. 'C:\Users\oddros') instead of '%USERPROFILE%'. My MAVEN_OPTS now looks like this:

-Djavax.net.ssl.trustStore=C:\Users\oddros\trust.jks -Djavax.net.ssl.trustStorePassword=changeit

I haven't tested this but could you use a set of pairs of iterators instead? Each iterator pair would represent the begin and end iterator of the sequence vector. E.g.:

typedef std::vector<int> Seq;
typedef std::pair<Seq::const_iterator, Seq::const_iterator> SeqRange;

bool operator< (const SeqRange& lhs, const SeqRange& rhs)
{
    Seq::const_iterator lhsNext = lhs.first;
    Seq::const_iterator rhsNext = rhs.first;

    while (lhsNext != lhs.second && rhsNext != rhs.second)
        if (*lhsNext < *rhsNext)
            return true;
        else if (*lhsNext > *rhsNext)
            return false;

    return false;
}

typedef std::set<SeqRange, std::less<SeqRange> > SeqSet;

Seq sequences;

void test (const SeqSet& seqSet, const SeqRange& seq)
{
    bool find = seqSet.find (seq) != seqSet.end ();
    bool find2 = seqSet.find (SeqRange (seq.first + 1, seq.second)) != seqSet.end ();
}

Obviously the vectors have to be held elsewhere as before. Also if a sequence vector is modified then its entry in the set would have to be removed and re-added as the iterators may have changed.

"datetime" expects the date to be formated like this: YYYY-MM-DD HH:MM:SS

so format your date like that when you are inserting.

I think about it in terms of information. Any problem consists of learning a certain number of bits.

Your basic tool is the concept of decision points and their entropy. The entropy of a decision point is the average information it will give you. For example, if a program contains a decision point with two branches, it's entropy is the sum of the probability of each branch times the log₂ of the inverse probability of that branch. That's how much you learn by executing that decision.

For example, an if statement having two branches, both equally likely, has an entropy of 1/2 * log(2/1) + 1/2 * log(2/1) = 1/2 * 1 + 1/2 * 1 = 1. So its entropy is 1 bit.

Suppose you are searching a table of N items, like N=1024. That is a 10-bit problem because log(1024) = 10 bits. So if you can search it with IF statements that have equally likely outcomes, it should take 10 decisions.

That's what you get with binary search.

Suppose you are doing linear search. You look at the first element and ask if it's the one you want. The probabilities are 1/1024 that it is, and 1023/1024 that it isn't. The entropy of that decision is 1/1024*log(1024/1) + 1023/1024 * log(1024/1023) = 1/1024 * 10 + 1023/1024 * about 0 = about .01 bit. You've learned very little! The second decision isn't much better. That is why linear search is so slow. In fact it's exponential in the number of bits you need to learn.

Suppose you are doing indexing. Suppose the table is pre-sorted into a lot of bins, and you use some of all of the bits in the key to index directly to the table entry. If there are 1024 bins, the entropy is 1/1024 * log(1024) + 1/1024 * log(1024) + ... for all 1024 possible outcomes. This is 1/1024 * 10 times 1024 outcomes, or 10 bits of entropy for that one indexing operation. That is why indexing search is fast.

Now think about sorting. You have N items, and you have a list. For each item, you have to search for where the item goes in the list, and then add it to the list. So sorting takes roughly N times the number of steps of the underlying search.

So sorts based on binary decisions having roughly equally likely outcomes all take about O(N log N) steps. An O(N) sort algorithm is possible if it is based on indexing search.

I've found that nearly all algorithmic performance issues can be looked at in this way.

• Optional.map():

Takes every element and if the value exists, it is passed to the function:

Optional<T> optionalValue = ...;
Optional<Boolean> added = optionalValue.map(results::add);

Now added has one of three values: true or false wrapped into an Optional , if optionalValue was present, or an empty Optional otherwise.

If you don't need to process the result you can simply use ifPresent(), it doesn't have return value:

optionalValue.ifPresent(results::add); 

• Optional.flatMap():

Works similar to the same method of streams. Flattens out the stream of streams. With the difference that if the value is presented it is applied to function. Otherwise, an empty optional is returned.

You can use it for composing optional value functions calls.

Suppose we have methods:

public static Optional<Double> inverse(Double x) {
    return x == 0 ? Optional.empty() : Optional.of(1 / x);
}

public static Optional<Double> squareRoot(Double x) {
    return x < 0 ? Optional.empty() : Optional.of(Math.sqrt(x));
}

Then you can compute the square root of the inverse, like:

Optional<Double> result = inverse(-4.0).flatMap(MyMath::squareRoot);

or, if you prefer:

Optional<Double> result = Optional.of(-4.0).flatMap(MyMath::inverse).flatMap(MyMath::squareRoot);

If either the inverse() or the squareRoot() returns Optional.empty(), the result is empty.

An alternative to @Steve's code.

DECLARE
  CURSOR foo_cur IS 
    SELECT NEEDED_FIELD WHERE condition ;
BEGIN
  FOR foo_rec IN foo_cur LOOP
     ...
  END LOOP;
EXCEPTION
  WHEN OTHERS THEN
    RAISE;
END ;

The loop is not executed if there is no data. Cursor FOR loops are the way to go - they help avoid a lot of housekeeping. An even more compact solution:

DECLARE
BEGIN
  FOR foo_rec IN (SELECT NEEDED_FIELD WHERE condition) LOOP
     ...
  END LOOP;
EXCEPTION
  WHEN OTHERS THEN
    RAISE;
END ;

Which works if you know the complete select statement at compile time.

If I'm reading your question correctly, objects in general are agnostic about where they are contained. They don't know who their parents are. To find that information, you have to parse the parent data structure. The DOM has ways of doing this for us when you're talking about element objects in a document, but it looks like you're talking about vanilla objects.

Use @Column annotation and define its length attribute. Check Hibernate's documentation for references (section 2.2.2.3).

You should be able to do this with JavaScript:

<input type="button" value="Click Me!" onclick="submitForms()" />

If your forms have IDs:

submitForms = function(){
    document.getElementById("form1").submit();
    document.getElementById("form2").submit();
}

If your forms don't have IDs but have names:

submitForms = function(){
    document.forms["form1"].submit();
    document.forms["form2"].submit();
}

For anyone who encounters this issue on Windows i couldn't find my answer on google at all. I just tried running composer require ext-curl and this worked. Alternatively add the following in your composer.json file:

I'm a total noob, I came here to figure out VB's 'not equal to' syntax, so I figured I'd throw it in here in case someone else needed it:

<%If Not boolean_variable%>Do this if boolean_variable is false<%End If%>

I Had the same problem, in my case, was because i was returned a digit:

def __str__(self):
    return self.code

str is waiting for a str, not another.

now work good with:

def __str__(self):
    return self.name

where name is a STRING.

If the 2nd company is happy for you to access their content in an IFrame then they need to take the restriction off - they can do this fairly easily in the IIS config.

There's nothing you can do to circumvent it and anything that does work should get patched quickly in a security hotfix. You can't tell the browser to just render the frame if the source content header says not allowed in frames. That would make it easier for session hijacking.

If the content is GET only you don't post data back then you could get the page server side and proxy the content without the header, but then any post back should get invalidated.

Workspaces can only be open in one copy of eclipse at once. Further, you took away your own write access from the looks of it. All the users in question have to have the 'admin' group for what you did to even work a little.

var newString = string.substr(0,string.indexOf(','));

As a rule passing by const reference is better. But if you need to modify you function argument locally you should better use passing by value. For some basic types the performance in general the same both for passing by value and by reference. Actually reference internally represented by pointer, that is why you can expect for instance that for pointer both passing are the same in terms of performance, or even passing by value can be faster because of needless dereference.

Pointer arithmetic is not allowed on void* pointers.

The example you are using is wrong. See the man page for easy_setopt. In the example write_data uses its own FILE, *outfile, and not the fp that was specified in CURLOPT_WRITEDATA. That's why closing fp causes problems - it's not even opened.

This is more or less what it should look like (no libcurl available here to test)

#include <stdio.h>

/* For older cURL versions you will also need 
#include <curl/types.h>
#include <curl/easy.h>

    size_t written = fwrite(ptr, size, nmemb, stream);
    return written;
}

    curl = curl_easy_init();
    if (curl) {
        fp = fopen(outfilename,"wb");
        curl_easy_setopt(curl, CURLOPT_URL, url);

Updated: as suggested by @rsethc types.h and easy.h aren't present in current cURL versions anymore.

This is ridiculous but I just have rebooted my machine (mac) and the problem was gone like it has never happened. I hate to sound like a support guy...

If you've copied this directly, then:

->setCellValue('B2', Ackermann') 

should be

->setCellValue('B2', 'Ackermann') 

In answer to your question:

Get the data that you want from limesurvey, and use setCellValue() to store those data values in the cells where you want to store it.

The Quadratic.php example file in /Tests might help as a starting point: it takes data from an input form and sets it to cells in an Excel workbook.

EDIT

An extremely simplistic example:

// Create your database query
$query = "SELECT * FROM myDataTable";  

// Execute the database query
$result = mysql_query($query) or die(mysql_error());

// Instantiate a new PHPExcel object
$objPHPExcel = new PHPExcel(); 
// Set the active Excel worksheet to sheet 0
$objPHPExcel->setActiveSheetIndex(0); 
// Initialise the Excel row number
$rowCount = 1; 
// Iterate through each result from the SQL query in turn
// We fetch each database result row into $row in turn
while($row = mysql_fetch_array($result)){ 
    // Set cell An to the "name" column from the database (assuming you have a column called name)
    //    where n is the Excel row number (ie cell A1 in the first row)
    $objPHPExcel->getActiveSheet()->SetCellValue('A'.$rowCount, $row['name']); 
    // Set cell Bn to the "age" column from the database (assuming you have a column called age)
    //    where n is the Excel row number (ie cell A1 in the first row)
    $objPHPExcel->getActiveSheet()->SetCellValue('B'.$rowCount, $row['age']); 
    // Increment the Excel row counter
    $rowCount++; 
} 

// Instantiate a Writer to create an OfficeOpenXML Excel .xlsx file
$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel); 
// Write the Excel file to filename some_excel_file.xlsx in the current directory
$objWriter->save('some_excel_file.xlsx'); 

EDIT #2

Using your existing code as the basis

// Instantiate a new PHPExcel object 
$objPHPExcel = new PHPExcel();  
// Set the active Excel worksheet to sheet 0 
$objPHPExcel->setActiveSheetIndex(0);  
// Initialise the Excel row number 
$rowCount = 1;  

//start of printing column names as names of MySQL fields  
$column = 'A';
for ($i = 1; $i < mysql_num_fields($result); $i++)  
{
    $objPHPExcel->getActiveSheet()->setCellValue($column.$rowCount, mysql_field_name($result,$i));
    $column++;
}
//end of adding column names  

//start while loop to get data  
$rowCount = 2;  
while($row = mysql_fetch_row($result))  
{  
    $column = 'A';
    for($j=1; $j<mysql_num_fields($result);$j++)  
    {  
        if(!isset($row[$j]))  
            $value = NULL;  
        elseif ($row[$j] != "")  
            $value = strip_tags($row[$j]);  
        else  
            $value = "";  

        $objPHPExcel->getActiveSheet()->setCellValue($column.$rowCount, $value);
        $column++;
    }  
    $rowCount++;
} 


// Redirect output to a client’s web browser (Excel5) 
header('Content-Type: application/vnd.ms-excel'); 
header('Content-Disposition: attachment;filename="Limesurvey_Results.xls"'); 
header('Cache-Control: max-age=0'); 
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5'); 
$objWriter->save('php://output');

If you have a ADO.Net DataTable you could do

int sum = 0;
foreach(DataRow dr in dataTable.Rows)
{
   sum += Convert.ToInt32(dr["Amount"]);
}

If you want to query the database table, you could use

Select Sum(Amount) From DataTable

If the HTTP Connection doesn't timeout, You can implement the timeout checker in the background thread itself (AsyncTask, Service, etc), the following class is an example for Customize AsyncTask which timeout after certain period

public abstract class AsyncTaskWithTimer<Params, Progress, Result> extends
    AsyncTask<Params, Progress, Result> {

private static final int HTTP_REQUEST_TIMEOUT = 30000;

@Override
protected Result doInBackground(Params... params) {
    createTimeoutListener();
    return doInBackgroundImpl(params);
}

private void createTimeoutListener() {
    Thread timeout = new Thread() {
        public void run() {
            Looper.prepare();

            final Handler handler = new Handler();
            handler.postDelayed(new Runnable() {
                @Override
                public void run() {

                    if (AsyncTaskWithTimer.this != null
                            && AsyncTaskWithTimer.this.getStatus() != Status.FINISHED)
                        AsyncTaskWithTimer.this.cancel(true);
                    handler.removeCallbacks(this);
                    Looper.myLooper().quit();
                }
            }, HTTP_REQUEST_TIMEOUT);

            Looper.loop();
        }
    };
    timeout.start();
}

abstract protected Result doInBackgroundImpl(Params... params);
}

A Sample for this

public class AsyncTaskWithTimerSample extends AsyncTaskWithTimer<Void, Void, Void> {

    @Override
    protected void onCancelled(Void void) {
        Log.d(TAG, "Async Task onCancelled With Result");
        super.onCancelled(result);
    }

    @Override
    protected void onCancelled() {
        Log.d(TAG, "Async Task onCancelled");
        super.onCancelled();
    }

    @Override
    protected Void doInBackgroundImpl(Void... params) {
        // Do background work
        return null;
    };
 }

It does work in Firefox (including 2.0.0.20). See http://jsbin.com/akili (add /edit to the url to edit):

<p id="one">One</p>
<a href="#" onclick="document.getElementById('one').id = 'two'; return false">Link2</a>

The first click changes the id to "two", the second click errors because the element with id="one" now can't be found!

Perhaps you have another element already with id="two" (FYI you can't have more than one element with the same id).

You can check that theHref is defined by checking against undefined.

if (undefined !== theHref && theHref.length) {
    // `theHref` is not undefined and has truthy property _length_
    // do stuff
} else {
    // do other stuff
}

If you want to also protect yourself against falsey values like null then check theHref is truthy, which is a little shorter

if (theHref && theHref.length) {
    // `theHref` is truthy and has truthy property _length_
}

Obscenity Filters: Bad Idea, or Incredibly Intercoursing Bad Idea?

Also, one can't forget The Untold History of Toontown's SpeedChat, where even using a "safe-word whitelist" resulted in a 14 year old quickly circumventing it with: "I want to stick my long-necked Giraffe up your fluffy white bunny."

Bottom line: Ultimately, for any system that you implement, there is absolutely no substitute for human review (whether peer or otherwise). Feel free to implement a rudimentary tool to get rid of the drive-by's, but for the determined troll, you absolutely must have a non-algorithm-based approach.

A system that removes anonymity and introduces accountability (something that Stack Overflow does well) is helpful also, particularly in order to help combat John Gabriel's G.I.F.T.

You also asked where you can get profanity lists to get you started -- one open-source project to check out is Dansguardian -- check out the source code for their default profanity lists. There is also an additional third party Phrase List that you can download for the proxy that may be a helpful gleaning point for you.

Edit in response the question edit: Thanks for the clarification on what you're trying to do. In that case, if you're just trying to do a simple word filter, there are two ways you can do it. One is to create a single long regexp with all of the banned phrases that you want to censor, and merely do a regex find/replace with it. A regex like:

$filterRegex = "(boogers|snot|poop|shucks|argh)"

and run it on your input string using preg_match() to wholesale test for a hit,

or preg_replace() to blank them out.

You can also load those functions up with arrays rather than a single long regex, and for long word lists, it may be more manageable. See the preg_replace() for some good examples as to how arrays can be used flexibly.

For additional PHP programming examples, see this page for a somewhat advanced generic class for word filtering that *'s out the center letters from censored words, and this previous Stack Overflow question that also has a PHP example (the main valuable part in there is the SQL-based filtered word approach -- the leet-speak compensator can be dispensed with if you find it unnecessary).

You also added: "Getting the list of words in the first place is the real question." -- in addition to some of the previous Dansgaurdian links, you may find this handy .zip of 458 words to be helpful.

If you're feeling lazy, here's a terse method of handling conditions using || (or) and && (and) after the operation:

wget -q --tries=10 --timeout=20 --spider http://google.com || \
{ echo "Sorry you are Offline" && exit 1; }

This should be enough:

.nav.navbar-nav li a:hover {
  color: red;
}

I used string.js's latinise() method, which lets you do it like this:

var output = S(input).latinise().toString();

You just need to wrap object in ()

var arr = [{_x000D_
  id: 1,_x000D_
  name: 'bill'_x000D_
}, {_x000D_
  id: 2,_x000D_
  name: 'ted'_x000D_
}]_x000D_
_x000D_
var result = arr.map(person => ({ value: person.id, text: person.name }));_x000D_
console.log(result)

Add the $http, $scope services in the controller fucntion, sometimes if they are missing these errors occur.

This should work:

select * from syscat.tables

Perhaps not the most elegant solution but it works if you are not too picky!

bool IsInteger(double num) {
    return !num.ToString("0.################").Contains(".");
}

Strict aliasing is not allowing different pointer types to the same data.

This article should help you understand the issue in full detail.

Adding @wraps(f) above the wrapper function solved my issue.

def list_ownership(f):
    @wraps(f)
    def decorator(*args,**kwargs):
        return f(args,kwargs)
    return decorator

Decode it with the unicode-escape codec:

>>> a="Hello\u2026"
>>> a.decode('unicode-escape')
u'Hello\u2026'
>>> print _
Hello…

This is because for a non-unicode string the \u2026 is not recognised but is instead treated as a literal series of characters (to put it more clearly, 'Hello\\u2026'). You need to decode the escapes, and the unicode-escape codec can do that for you.

Note that you can get unicode to recognise it in the same way by specifying the codec argument:

>>> unicode(a, 'unicode-escape')
u'Hello\u2026'

But the a.decode() way is nicer.

I have found that using backticks to capture command output into a variable, adversly, yeilds one too many ps aux results, e.g. for a single running instance of abc.sh:

ps aux | grep -w "abc.sh" | grep -v grep | wc -l

returns "1". However,

count=`ps aux | grep -w "abc.sh" | grep -v grep | wc -l`
echo $count

returns "2"

Seems like using the backtick construction somehow temporarily creates another process. Could be the reason why the topicstarter could not make this work. Just need to decrement the $count var.

Your module and your class AthleteList have the same name. The line

import AthleteList

imports the module and creates a name AthleteList in your current scope that points to the module object. If you want to access the actual class, use

AthleteList.AthleteList

In particular, in the line

return(AthleteList(templ.pop(0), templ.pop(0), templ))

you are actually accessing the module object and not the class. Try

return(AthleteList.AthleteList(templ.pop(0), templ.pop(0), templ))

1) Use maven dependency plugin

Create a simple project with pom.xml only. Add your dependency and run:

mvn dependency:tree

Unfortunately dependency mojo must use pom.xml or you get following error:

Cannot execute mojo: tree. It requires a project with an existing pom.xml, but the build is not using one.

2) Find pom.xml of your artifact in maven central repository

Dependencies are described In pom.xml of your artifact. Find it using maven infrastructure.

Go to https://search.maven.org/ and enter your groupId and artifactId.

Or you can go to https://repo1.maven.org/maven2/ and navigate first using plugins groupId, later using artifactId and finally using its version.

For example see org.springframework:spring-core

3) Use maven dependency plugin against your artifact

Part of dependency artifact is a pom.xml. That specifies it's dependency. And you can execute mvn dependency:tree on this pom.

The code you posted gives the critical value for a one-sided test (Hence the answer to you question is simply:

abs(qt(0.25, 40)) # 75% confidence, 1 sided (same as qt(0.75, 40))
abs(qt(0.01, 40)) # 99% confidence, 1 sided (same as qt(0.99, 40))

Note that the t-distribution is symmetric. For a 2-sided test (say with 99% confidence) you can use the critical value

abs(qt(0.01/2, 40)) # 99% confidence, 2 sided

You can simulate it with using varargs, however then you should check it for too many arguments.

public void foo(int param1, int ... param2)
{
   int param2_
   if(param2.length == 0)
      param2_ = 2
   else if(para2.length == 1)
      param2_ = param2[0]
   else
      throw new TooManyArgumentsException(); // user provided too many arguments,

   // rest of the code
}

However this approach is not a good way of doing this, therefore it is better to use overloading.

The following URL always gives a timeout, and combines the best of @Alexander and @Emu's answers above:

http://example.com:81

Using example.com:81 is an improvement on Alexander's answer because example.com is reserved by the DNS standard, so it will always be unreachable, unlike google.com:81, which may change if Google feels like it. Also, because example.com is defined to be unreachable, you won't be flooding Google's servers.

I'd say it's an improvement over @emu's answer because it's a lot easier to remember.

You don't need to pass the parameter, you can get it using .attr() method

$(function(){
    $('elements-to-match').click(function(){
        alert("The id is "+ $(this).attr("id") );
    });
});

1. First of all check latest Chrome version (This is your browser Chrome version) link

2. Download same version of Chrome Web Driver from this link

Do not download latest Chrome Web Driver if it does not match your Chrome Browser version.

Note: When I write this message, latest Chrome Browser version is 84 but latest Chrome Driver version is 85. I am using Chrome Driver version 84 so that Chrome Driver and Chrome Browser versions are the same.

In a completely different and simpler perspective:

• if you are relying on Google for showing your maps, markers, polygons, whatever, then let the calculations be done by Google!
• you save resources on your server and you simply store the latitude and longitude together as a single string (VARCHAR), E.g.: "-0000.0000001,-0000.000000000000001" (35 length and if a number has more than 7 decimal digits then it gets rounded);
• if Google returns more than 7 decimal digits per number, you can get that data stored in your string anyway, just in case you want to detect some flees or microbes in the future;
• you can use their distance matrix or their geometry library for calculating distances or detecting points in certain areas with calls as simple as this: google.maps.geometry.poly.containsLocation(latLng, bermudaTrianglePolygon))
• there are plenty of "server-side" APIs you can use (in Python, Ruby on Rails, PHP, CodeIgniter, Laravel, Yii, Zend Framework, etc.) that use Google Maps API.

This way you don't need to worry about indexing numbers and all the other problems associated with data types that may screw up your coordinates.

use form shown event and set

MyTextBox.Focus();

This happens because you have added your worker directory as a volume to your docker-compose.yml, as the volume is not mounted during the build.

When docker builds the image, the node_modules directory is created within the worker directory, and all the dependencies are installed there. Then on runtime the worker directory from outside docker is mounted into the docker instance (which does not have the installed node_modules), hiding the node_modules you just installed. You can verify this by removing the mounted volume from your docker-compose.yml.

A workaround is to use a data volume to store all the node_modules, as data volumes copy in the data from the built docker image before the worker directory is mounted. This can be done in the docker-compose.yml like this:

redis:
    image: redis
worker:
    build: ./worker
    command: npm start
    ports:
        - "9730:9730"
    volumes:
        - ./worker/:/worker/
        - /worker/node_modules
    links:
        - redis

I'm not entirely certain whether this imposes any issues for the portability of the image, but as it seems you are primarily using docker to provide a runtime environment, this should not be an issue.

If you want to read more about volumes, there is a nice user guide available here: https://docs.docker.com/userguide/dockervolumes/

EDIT: Docker has since changed it's syntax to require a leading ./ for mounting in files relative to the docker-compose.yml file.

+1 for TopCoder UML Tool after I had tried most of other free tools.
My reasons are:

1) The tool can save UML diagrams in the human-readable format XMI, so the file can be fed to the version control system easily.

2) Support of Undo/Redo (this is the reason I've discharged ArgoUML).

3) The diagram is kept in one single file, and not linked tightly with "workspace" or "project".

StarUML is also good, though is old. Unfortunatley it is not developed/maintained any longer.

I found a work around but with this I'll need to annotate each date's setter throughout the project. Is there a way in which I can specify the format while creating the ObjectMapper?

Here's what I did:

public class CustomJsonDateDeserializer extends JsonDeserializer<Date>
{
    @Override
    public Date deserialize(JsonParser jsonParser,
            DeserializationContext deserializationContext) throws IOException, JsonProcessingException {

        SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
        String date = jsonParser.getText();
        try {
            return format.parse(date);
        } catch (ParseException e) {
            throw new RuntimeException(e);
        }

    }

}

And annotated each Date field's setter method with this:

@JsonDeserialize(using = CustomJsonDateDeserializer.class)
