Apache 2 mod_headers

You could also enable Apache 2 mod_headers. On Fedora it's already enabled by default. If you use Ubuntu/Debian, enable it like this:

# First enable headers module for Apache 2,
# and then restart the Apache2 service
a2enmod headers
apache2 -k graceful

On Ubuntu/Debian you can configure headers in the file /etc/apache2/conf-enabled/security.conf

#
# Setting this header will prevent MSIE from interpreting files as something
# else than declared by the content type in the HTTP headers.
# Requires mod_headers to be enabled.
#
#Header set X-Content-Type-Options: "nosniff"

#
# Setting this header will prevent other sites from embedding pages from this
# site as frames. This defends against clickjacking attacks.
# Requires mod_headers to be enabled.
#
Header always set X-Frame-Options: "sameorigin"
Header always set X-Content-Type-Options nosniff
Header always set X-XSS-Protection "1; mode=block"
Header always set X-Permitted-Cross-Domain-Policies "master-only"
Header always set Cache-Control "no-cache, no-store, must-revalidate"
Header always set Pragma "no-cache"
Header always set Expires "-1"
Header always set Content-Security-Policy: "default-src 'none';"
Header always set Content-Security-Policy: "script-src 'self' www.google-analytics.com adserver.example.com www.example.com;"
Header always set Content-Security-Policy: "style-src 'self' www.example.com;"

Note: This is the bottom part of the file. Only the last three entries are CSP settings.

The first parameter is the directive, the second is the sources to be white-listed. I've added Google analytics and an adserver, which you might have. Furthermore, I found that if you have aliases, e.g, www.example.com and example.com configured in Apache 2 you should add them to the white-list as well.

Inline code is considered harmful, and you should avoid it. Copy all the JavaScript code and CSS to separate files and add them to the white-list.

While you're at it you could take a look at the other header settings and install mod_security

The issue is that the original axiosTest() function isn't returning the promise. Here's an extended explanation for clarity:

function axiosTest() {
    // create a promise for the axios request
    const promise = axios.get(url)

    // using .then, create a new promise which extracts the data
    const dataPromise = promise.then((response) => response.data)

    // return it
    return dataPromise
}

// now we can use that data from the outside!
axiosTest()
    .then(data => {
        response.json({ message: 'Request received!', data })
    })
    .catch(err => console.log(err))

The function can be written more succinctly:

function axiosTest() {
    return axios.get(url).then(response => response.data)
}

Or with async/await:

async function axiosTest() {
    const response = await axios.get(url)
    return response.data
}

For me, i deleted the migration file(in your case "201203170856167_left") from Migrations folder, and then ran the below command in Package Manager console

Add-Migration <Parameter>
Update-Database

Just going to add a simple example to what everyone has explained,

json.load()

json.load can deserialize a file itself i.e. it accepts a file object, for example,

# open a json file for reading and print content using json.load
with open("/xyz/json_data.json", "r") as content:
  print(json.load(content))

will output,

{u'event': {u'id': u'5206c7e2-da67-42da-9341-6ea403c632c7', u'name': u'Sufiyan Ghori'}}

If I use json.loads to open a file instead,

# you cannot use json.loads on file object
with open("json_data.json", "r") as content:
  print(json.loads(content))

I would get this error:

TypeError: expected string or buffer

json.loads()

json.loads() deserialize string.

So in order to use json.loads I will have to pass the content of the file using read() function, for example,

using content.read() with json.loads() return content of the file,

with open("json_data.json", "r") as content:
  print(json.loads(content.read()))

Output,

{u'event': {u'id': u'5206c7e2-da67-42da-9341-6ea403c632c7', u'name': u'Sufiyan Ghori'}}

That's because type of content.read() is string, i.e. <type 'str'>

If I use json.load() with content.read(), I will get error,

with open("json_data.json", "r") as content:
  print(json.load(content.read()))

Gives,

AttributeError: 'str' object has no attribute 'read'

So, now you know json.load deserialze file and json.loads deserialize a string.

Another example,

sys.stdin return file object, so if i do print(json.load(sys.stdin)), I will get actual json data,

cat json_data.json | ./test.py

{u'event': {u'id': u'5206c7e2-da67-42da-9341-6ea403c632c7', u'name': u'Sufiyan Ghori'}}

If I want to use json.loads(), I would do print(json.loads(sys.stdin.read())) instead.

I am tempted to squeeze in my favourite solution. The resulting table will consist of 2 columns: PosIdx for position of the found integer; and Value in integer.

create function FnSplitToTableInt
(
    @param nvarchar(4000)
)
returns table as
return
    with Numbers(Number) as 
    (
        select 1 
        union all 
        select Number + 1 from Numbers where Number < 4000
    ),
    Found as
    (
        select 
            Number as PosIdx,
            convert(int, ltrim(rtrim(convert(nvarchar(4000), 
                substring(@param, Number, 
                charindex(N',' collate Latin1_General_BIN, 
                @param + N',', Number) - Number))))) as Value
        from   
            Numbers 
        where  
            Number <= len(@param)
        and substring(N',' + @param, Number, 1) = N',' collate Latin1_General_BIN
    )
    select 
        PosIdx, 
        case when isnumeric(Value) = 1 
            then convert(int, Value) 
            else convert(int, null) end as Value 
    from 
        Found

It works by using recursive CTE as the list of positions, from 1 to 100 by default. If you need to work with string longer than 100, simply call this function using 'option (maxrecursion 4000)' like the following:

select * from FnSplitToTableInt
(
    '9, 8, 7, 6, 5, 4, 3, 2, 1, 0, ' + 
    '9, 8, 7, 6, 5, 4, 3, 2, 1, 0, ' +
    '9, 8, 7, 6, 5, 4, 3, 2, 1, 0, ' +
    '9, 8, 7, 6, 5, 4, 3, 2, 1, 0, ' +
    '9, 8, 7, 6, 5, 4, 3, 2, 1, 0'
) 
option (maxrecursion 4000)

I cannot replicate the results discussed here.

I don't know if poor benchmark code is to blame, or what, but the two methods are within 10% of each other on my machine using the following code, and one loop is usually just slightly faster than two - as you'd expect.

Array sizes ranged from 2^16 to 2^24, using eight loops. I was careful to initialize the source arrays so the += assignment wasn't asking the FPU to add memory garbage interpreted as a double.

I played around with various schemes, such as putting the assignment of b[j], d[j] to InitToZero[j] inside the loops, and also with using += b[j] = 1 and += d[j] = 1, and I got fairly consistent results.

As you might expect, initializing b and d inside the loop using InitToZero[j] gave the combined approach an advantage, as they were done back-to-back before the assignments to a and c, but still within 10%. Go figure.

Hardware is Dell XPS 8500 with generation 3 Core i7 @ 3.4 GHz and 8 GB memory. For 2^16 to 2^24, using eight loops, the cumulative time was 44.987 and 40.965 respectively. Visual C++ 2010, fully optimized.

PS: I changed the loops to count down to zero, and the combined method was marginally faster. Scratching my head. Note the new array sizing and loop counts.

I'm not sure why it was decided that MFLOPS was a relevant metric. I though the idea was to focus on memory accesses, so I tried to minimize the amount of floating point computation time. I left in the +=, but I am not sure why.

A straight assignment with no computation would be a cleaner test of memory access time and would create a test that is uniform irrespective of the loop count. Maybe I missed something in the conversation, but it is worth thinking twice about. If the plus is left out of the assignment, the cumulative time is almost identical at 31 seconds each.

On Centos 5 I was getting all sorts of errors trying to make changes to some variable values from the MySQL shell, after having logged in with the proper uid and pw (with root access). The error that I was getting was something like this:

mysql> -- Set some variable value, for example
mysql> SET GLOBAL general_log='ON';
ERROR 1227 (42000): Access denied; you need (at least one of) the SUPER privilege(s) for this operation

In a moment of extreme serendipity I did the following:

OS-Shell> sudo mysql                          # no DB uid, no DB pw

Kindly note that I did not provide the DB uid and password

mysql> show variables;
mysql> -- edit the variable of interest to the desired value, for example
mysql> SET GLOBAL general_log='ON';

It worked like a charm

For anyone who might come looking for the solution.

The following is the un-installation for PostgreSQL 9.1 installed using the EnterpriseDB installer. You most probably have to replace folder /9.1/ with your version number. If /Library/Postgresql/ doesn't exist then you probably installed PostgreSQL with a different method like homebrew or Postgres.app.

To remove the EnterpriseDB One-Click install of PostgreSQL 9.1:

1. Open a terminal window. Terminal is found in: Applications->Utilities->Terminal

2. Run the uninstaller:

   sudo /Library/PostgreSQL/9.1/uninstall-postgresql.app/Contents/MacOS/installbuilder.sh
   

   If you installed with the Postgres Installer, you can do:

   open /Library/PostgreSQL/9.2/uninstall-postgresql.app
   

   It will ask for the administrator password and run the uninstaller.

3. Remove the PostgreSQL and data folders. The Wizard will notify you that these were not removed.

   sudo rm -rf /Library/PostgreSQL
   

4. Remove the ini file:

   sudo rm /etc/postgres-reg.ini
   

5. Remove the PostgreSQL user using System Preferences -> Users & Groups.

   1. Unlock the settings panel by clicking on the padlock and entering your password.
   2. Select the PostgreSQL user and click on the minus button.

6. Restore your shared memory settings:

   sudo rm /etc/sysctl.conf
   

That should be all! The uninstall wizard would have removed all icons and start-up applications files so you don't have to worry about those.

There is bug a iOS 9 beta 4: the separator line appears between UITableViewCells even if you set separatorStyle to UITableViewCellSeparatorStyleNone from the storyboard. To get around this, you have to set it from code, because as of now there is a bug from storyboard. Hope they will fix it in future beta.

Here's the code to set it:

[self.tableView setSeparatorStyle:UITableViewCellSeparatorStyleNone];

Questioner here, I have got to say getting a tool that does not take 5 minutes to answer any click makes it a lot easier to find potential memory leaks.

Since people are suggesting several tools ( I only tried visual wm since I got that in the JDK and JProbe trial ) I though I should suggest a free / open source tool built on the Eclipse platform, the Memory Analyzer (sometimes referenced as the SAP memory analyzer) available on http://www.eclipse.org/mat/ .

What is really cool about this tool is that it indexed the heap dump when I first opened it which allowed it to show data like retained heap without waiting 5 minutes for each object (pretty much all operations were tons faster than the other tools I tried).

When you open the dump, the first screen shows you a pie chart with the biggest objects (counting retained heap) and one can quickly navigate down to the objects that are to big for comfort. It also has a Find likely leak suspects which I reccon can come in handy, but since the navigation was enough for me I did not really get into it.

success is the callback that is invoked when the request is successful and is part of the $.ajax call. done is actually part of the jqXHR object returned by $.ajax(), and replaces success in jQuery 1.8.

When iterating over cell arrays of strings, the loop variable (let's call it f) becomes a single-element cell array. Having to write f{1} everywhere gets tedious, and modifying the loop variable provides a clean workaround.

% This example transposes each field of a struct.
s.a = 1:3;
s.b = zeros(2,3);
s % a: [1 2 3]; b: [2x3 double]
for f = fieldnames(s)'
    s.(f{1}) = s.(f{1})';
end
s % a: [3x1 double]; b: [3x2 double]

% Redefining f simplifies the indexing.
for f = fieldnames(s)'
    f = f{1};
    s.(f) = s.(f)';
end
s % back to a: [1 2 3]; b: [2x3 double]

First, create numpy array then convert it into matrix. See the code below:

import numpy

B = numpy.random.random((3, 4)) #its ndArray
C = numpy.matrix(B)# it is matrix
print(type(B))
print(type(C)) 
print(C)

Well after a bit of hacking of Tim Golden's script, I have the following which seems to work quite well:

import os

import win32file
import win32con

path_to_watch = "." # look at the current directory
file_to_watch = "test.txt" # look for changes to a file called test.txt

def ProcessNewData( newData ):
    print "Text added: %s"%newData

# Set up the bits we'll need for output
ACTIONS = {
  1 : "Created",
  2 : "Deleted",
  3 : "Updated",
  4 : "Renamed from something",
  5 : "Renamed to something"
}
FILE_LIST_DIRECTORY = 0x0001
hDir = win32file.CreateFile (
  path_to_watch,
  FILE_LIST_DIRECTORY,
  win32con.FILE_SHARE_READ | win32con.FILE_SHARE_WRITE,
  None,
  win32con.OPEN_EXISTING,
  win32con.FILE_FLAG_BACKUP_SEMANTICS,
  None
)

# Open the file we're interested in
a = open(file_to_watch, "r")

# Throw away any exising log data
a.read()

# Wait for new data and call ProcessNewData for each new chunk that's written
while 1:
  # Wait for a change to occur
  results = win32file.ReadDirectoryChangesW (
    hDir,
    1024,
    False,
    win32con.FILE_NOTIFY_CHANGE_LAST_WRITE,
    None,
    None
  )

  # For each change, check to see if it's updating the file we're interested in
  for action, file in results:
    full_filename = os.path.join (path_to_watch, file)
    #print file, ACTIONS.get (action, "Unknown")
    if file == file_to_watch:
        newText = a.read()
        if newText != "":
            ProcessNewData( newText )

It could probably do with a load more error checking, but for simply watching a log file and doing some processing on it before spitting it out to the screen, this works well.

Thanks everyone for your input - great stuff!

Some cases you might want to kill all the process running in a specific port. For example, if I am running a node app on 3000 port and I want to kill that and start a new one; then I found this command useful.

Find the process IDs running on TCP port 3000 and kill it

kill -9 `lsof -i TCP:3000 | awk '/LISTEN/{print $2}'`

How about traits, in an STL fashion? For instance:

enum Foo
{
    Bar,
    Baz
};

write an

std::numeric_limits<enum Foo>::max()

specialization (possibly constexpr if you use c++11). Then, in your test code provide any static assertions to maintain the constraints that std::numeric_limits::max() = last_item.

#pragma comment(lib,"ntdll.lib")
EXTERN_C NTSTATUS NTAPI NtSuspendProcess(IN HANDLE ProcessHandle);

void SuspendSelf(){
    NtSuspendProcess(GetCurrentProcess());
}

ntdll contains the exported function NtSuspendProcess, pass the handle to a process to do the trick.

Note that you also can use insert in order to put number into the required position within list:

initList = [1,2,3,4,5]
initList.insert(2, 10) # insert(pos, val) => initList = [1,2,10,3,4,5]

And also note that in python you can always get a list length using method len()

I have found Adobe Dreamweaver to be quite good at that. However, it's not free.

Alternatively you could update brew by installing it again. (Think I did this as El Capitan changed something)

Note: this is a heavy handed approach that will remove all applications installed via brew!

Try to install brew a fresh and it will tell how to uninstall.

At original time of writing to uninstall:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"

Edit: As of 2020 to uninstall:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh)"

To select data in numerical range you can use BETWEEN which is inclusive.

SELECT JOB FROM MYTABLE WHERE ID BETWEEN 10 AND 15;

Generally, .c and .h files are for C or C-compatible code, everything else is C++.

Many folks prefer to use a consistent pairing for C++ files: .cpp with .hpp, .cxx with .hxx, .cc with .hh, etc. My personal preference is for .cpp and .hpp.

Building on Oliver's answer - you might not always need to access a directive's inner methods, and in those cases you probably don't want to have to create a blank object and add a control attr to the directive just to prevent it from throwing an error (cannot set property 'takeTablet' of undefined).

You also might want to use the method in other places within the directive.

I would add a check to make sure scope.control exists, and set methods to it in a similar fashion to the revealing module pattern

app.directive('focusin', function factory() {
  return {
    restrict: 'E',
    replace: true,
    template: '<div>A:{{control}}</div>',
    scope: {
      control: '='
    },
    link : function (scope, element, attrs) {
      var takenTablets = 0;
      var takeTablet = function() {
        takenTablets += 1;  
      }

      if (scope.control) {
        scope.control = {
          takeTablet: takeTablet
        };
      }
    }
  };
});

Expanding on Nathans post. The following will do the job lot in one batch file.

@echo off

if %1.==Sub. goto %2

for %%f in (*.in) do call %0 Sub action %%~nf
goto end

:action
echo The file is %3
copy %3.in %3.out
ren %3.out monkeys_are_cool.txt

On OSX (and Solaris, apparently), the mkfile command is available as well:

mkfile 10g big_file

This makes a 10 GB file named "big_file". Found this approach here.

First, you need to understand that you have two documents: The frame and the container (which contains the frame).

The main obstacle with manipulating the frame from the container is that the frame loads asynchronously. You can't simply access it any time, you must know when it has finished loading. So you need a trick. The usual solution is to use window.parent in the frame to get "up" (into the document which contains the iframe tag).

Now you can call any method in the container document. This method can manipulate the frame (for example call some JavaScript in the frame with the parameters you need). To know when to call the method, you have two options:

1. Call it from body.onload of the frame.

2. Put a script element as the last thing into the HTML content of the frame where you call the method of the container (left as an exercise for the reader).

So the frame looks like this:

<script>
function init() { window.parent.setUpFrame(); return true; }
function yourMethod(arg) { ... }
</script>
<body onload="init();">...</body>

And the container like this:

<script>
function setUpFrame() { 
    var frame = window.frames['frame-id'];
    frame.yourMethod('hello');
}
</script>
<body><iframe name="frame-id" src="..."></iframe></body>

You can use this code

using (WebClient client = new WebClient()) {
                    Stream stream = client.OpenRead(imgUrl);
                    if (stream != null) {
                        Bitmap bitmap = new Bitmap(stream);
                        ImageFormat imageFormat = ImageFormat.Jpeg;
                        if (bitmap.RawFormat.Equals(ImageFormat.Png)) {
                            imageFormat = ImageFormat.Png;

Angular - equal width button group

Assuming you have an array of 'things' in your scope...

• Make sure the parent div has a width of 100%.
• Use ng-repeat to create the buttons within the button group.
• Use ng-style to calculate the width for each button.

<div class="btn-group"
     style="width: 100%;">
    <button ng-repeat="thing in things"
            class="btn btn-default"
            ng-style="{width: (100/things.length)+'%'}">
        {{thing}}
    </button>
</div>

Convert each character to its ASCII code, subtract the ASCII code for "a" and add 1. I'm deliberately leaving the code as an exercise.

This sounds like homework. If so, please tag it as such.

Also, this won't deal with upper case letters, since you didn't state any requirement to handle them, but if you need to then just lowercase the string before you start.

Oh, and this will only deal with the latin "a" through "z" characters without any accents, etc.

In order to query a table for the number of rows in that table, you want your query to be as efficient as possible. Reference.

Use something like this:

/**
 * Query the Number of Entries in a Sqlite Table
 * */
public long QueryNumEntries()
{
    SQLiteDatabase db = this.getReadableDatabase();
    return DatabaseUtils.queryNumEntries(db, "table_name");
}

Another approach is using UnboundID. Its api is very readable and shorter

Create a Ldap Connection

public static LDAPConnection getConnection() throws LDAPException {
    // host, port, username and password
    return new LDAPConnection("com.example.local", 389, "[email protected]", "admin");
}

Get filter result

public static List<SearchResultEntry> getResults(LDAPConnection connection, String baseDN, String filter) throws LDAPSearchException {
    SearchResult searchResult;

    if (connection.isConnected()) {
        searchResult = connection.search(baseDN, SearchScope.ONE, filter);

        return searchResult.getSearchEntries();
    }

    return null;
}

Get all Oragnization Units and Containers

String baseDN = "DC=com,DC=example,DC=local";
String filter = "(&(|(objectClass=organizationalUnit)(objectClass=container)))";

LDAPConnection connection = getConnection();        
List<SearchResultEntry> results = getResults(connection, baseDN, filter);

Get a specific Organization Unit

String baseDN = "DC=com,DC=example,DC=local";
String dn = "CN=Users,DC=com,DC=example,DC=local";

String filterFormat = "(&(|(objectClass=organizationalUnit)(objectClass=container))(distinguishedName=%s))";
String filter = String.format(filterFormat, dn);

LDAPConnection connection =  getConnection();

List<SearchResultEntry> results = getResults(connection, baseDN, filter);

Get all users under an Organizational Unit

String baseDN = "CN=Users,DC=com,DC=example,DC=local";
String filter = "(&(objectClass=user)(!(objectCategory=computer)))";

LDAPConnection connection =  getConnection();       
List<SearchResultEntry> results = getResults(connection, baseDN, filter);

Get a specific user under an Organization Unit

String baseDN = "CN=Users,DC=com,DC=example,DC=local";
String userDN = "CN=abc,CN=Users,DC=com,DC=example,DC=local";

String filterFormat = "(&(objectClass=user)(distinguishedName=%s))";
String filter = String.format(filterFormat, userDN);

LDAPConnection connection =  getConnection();
List<SearchResultEntry> results = getResults(connection, baseDN, filter);

Display result

for (SearchResultEntry e : results) {
    System.out.println("name: " + e.getAttributeValue("name"));
}

My problem was solved by changing the build variant as suggested by Stéphane , if anyone was struggling to find the "Build variants" as I did here is a screenshot where you can find it .

The simplest way to create signed/unsigned APKs using Eclipse and ADT is as follows:

1. Right click your project in the "Project Explorer"
2. Hover over "Android Tools"
3. Select either "Export Signed Application Package" or "Export Unsigned Application Package"

4. Select the location for the new APK file and click "Save".

   • NOTE: If you're trying to build a APK for beta distribution, you'll probably need to create a signed package, which requires a keystore. If you follow the "Signed Application" process in Eclipse ADT it will guide you through the process of creating a new keystore.

Hope this helps.

Also you may omit the AS keyword.
SELECT row1 Price, row2 'Other Price' FROM exampleDB.table1;
in this option readability is a bit degraded but you have desired result.

To state the obvious, the cup represents outerScopeVar.

Asynchronous functions be like...

The next version of dplyr will support an improved version of select that also incorporates renaming:

> mtcars2 <- select( mtcars, disp2 = disp )
> head( mtcars2 )
                  disp2
Mazda RX4         160
Mazda RX4 Wag     160
Datsun 710        108
Hornet 4 Drive    258
Hornet Sportabout 360
Valiant           225
> changes( mtcars, mtcars2 )
Changed variables:
      old         new
disp  0x105500400
disp2             0x105500400

Changed attributes:
      old         new
names 0x106d2cf50 0x106d28a98

I struggled with this as well but heres the solution. If you add " before and at the end of the csv string you are trying to display, it will consolidate them into 1 cell while honoring new line.

csvString += "\""+"Date Generated: \n" ; 
csvString += "Doctor: " + "\n"+"\"" + "\n"; 

Try this, it's simple and clear. I have found it from here : https://css-tricks.com/tinted-images-multiple-backgrounds/

.tinted-image {

  width: 300px;
  height: 200px;

  background: 
    /* top, transparent red */ 
    linear-gradient(
      rgba(255, 0, 0, 0.45), 
      rgba(255, 0, 0, 0.45)
    ),
    /* bottom, image */
    url(https://s3-us-west-2.amazonaws.com/s.cdpn.io/3/owl1.jpg);
}

To my knowledge, Ejabberd (http://www.ejabberd.im/) is the parent, this is XMPP server which provide quite good features of open source, Whatsapp uses some modified version of this, facebook messaging also uses a modified version of this. Some more chat applications likes Samsung's ChatOn, Nimbuzz messenger all use ejabberd based ones and Erlang solutions also have modified version of this ejabberd which they claim to be highly scalable and well tested with more performance improvements and renamed as MongooseIM.

Ejabberd is the server which has most of the featured implemented when compared to other. Since it is build in Erlang it is highly scalable horizontally.

I think a DTO can be a POCO. DTO is more about the usage of the object while POCO is more of the style of the object (decoupled from architectural concepts).

One example where a POCO is something different than DTO is when you're talking about POCO's inside your domain model/business logic model, which is a nice OO representation of your problem domain. You could use the POCO's throughout the whole application, but this could have some undesirable side effect such a knowledge leaks. DTO's are for instance used from the Service Layer which the UI communicates with, the DTO's are flat representation of the data, and are only used for providing the UI with data, and communicating changes back to the service layer. The service layer is in charge of mapping the DTO's both ways to the POCO domain objects.

Update Martin Fowler said that this approach is a heavy road to take, and should only be taken if there is a significant mismatch between the domain layer and the user interface.

The error comes up when you are trying to assign a list of numpy array of different length to a data frame, and it can be reproduced as follows:

A data frame of four rows:

df = pd.DataFrame({'A': [1,2,3,4]})

Now trying to assign a list/array of two elements to it:

df['B'] = [3,4]   # or df['B'] = np.array([3,4])

Both errors out:

ValueError: Length of values does not match length of index

Because the data frame has four rows but the list and array has only two elements.

Work around Solution (use with caution): convert the list/array to a pandas Series, and then when you do assignment, missing index in the Series will be filled with NaN:

df['B'] = pd.Series([3,4])

df
#   A     B
#0  1   3.0
#1  2   4.0
#2  3   NaN          # NaN because the value at index 2 and 3 doesn't exist in the Series
#3  4   NaN

For your specific problem, if you don't care about the index or the correspondence of values between columns, you can reset index for each column after dropping the duplicates:

df.apply(lambda col: col.drop_duplicates().reset_index(drop=True))

#   A     B
#0  1   1.0
#1  2   5.0
#2  7   9.0
#3  8   NaN

Looking for the possibility to put a powershell script into a batch file, I found this thread. The idea of walid2mi did not worked 100% for my script. But via a temporary file, containing the script it worked out. Here is the skeleton of the batch file:

You must run git fetch before you can compare your local repository against the files on your remote server.

This command only updates your remote tracking branches and will not affect your worktree until you call git merge or git pull.

To see the difference between your local branch and your remote tracking branch once you've fetched you can use git diff or git cherry as explained here.

The answers above all over complicate the story.

1. If you plan to have a mobile component, or need desktop users to work offline and then sync their work to a server you need CouchDB.
2. If your code will run only on the server then go with MongoDB

That's it. Unless you need CouchDB's (awesome) ability to replicate to mobile and desktop devices, MongoDB has the performance, community and tooling advantage at present.

In Bootstrap 4.3, col-xs-{value} is replaced by col-{value}

There is no change in sm, md, lg, xl remains the same.

Based on Aladin Q's solution, here is a helper function that I wrote, that will change the image in an imageview while running a little fade out / fade in animation:

public static void ImageViewAnimatedChange(Context c, final ImageView v, final Bitmap new_image) {
        final Animation anim_out = AnimationUtils.loadAnimation(c, android.R.anim.fade_out); 
        final Animation anim_in  = AnimationUtils.loadAnimation(c, android.R.anim.fade_in); 
        anim_out.setAnimationListener(new AnimationListener()
        {
            @Override public void onAnimationStart(Animation animation) {}
            @Override public void onAnimationRepeat(Animation animation) {}
            @Override public void onAnimationEnd(Animation animation)
            {
                v.setImageBitmap(new_image); 
                anim_in.setAnimationListener(new AnimationListener() {
                    @Override public void onAnimationStart(Animation animation) {}
                    @Override public void onAnimationRepeat(Animation animation) {}
                    @Override public void onAnimationEnd(Animation animation) {}
                });
                v.startAnimation(anim_in);
            }
        });
        v.startAnimation(anim_out);
    }

Had the same problem today. After some research i found a very useful --abort-on-uncaught-exception node.js option. Not only it provides much more verbose and useful error stack trace, but also saves core file on application crash allowing further debug.

Best solution so far that I have seen is in FastAdapter library for recycler views. It has a EndlessRecyclerOnScrollListener.

Here is an example usage: EndlessScrollListActivity

Once I used it for endless scrolling list I have realised that the setup is a very robust. I'd definitely recommend it.

in your servlet

 request.setAttribute("submitDone","done");
 return mapping.findForward("success");

In your jsp

<c:if test="${not empty submitDone}">
  <script>alert("Form submitted");
</script></c:if>

That is the backbone of CSS, the "cascade" in Cascading Style Sheets.

If you write your CSS rules in a single line it makes it easier to see the structure:

.area1 .item { color:red; }
.area2 .item { color:blue; }
.area2 .item span { font-weight:bold; }

Using multiple classes is also a good intermediate/advanced use of CSS, unfortunately there is a well known IE6 bug which limits this usage when writing cross browser code:

<div class="area1 larger"> .... </div>

.area1 { width:200px; }
.area1.larger { width:300px; }

IE6 IGNORES the first selector in a multi-class rule, so IE6 actually applies the .area1.larger rule as

/*.area1*/.larger { ... }

Meaning it will affect ALL .larger elements.

It's a very nasty and unfortunate bug (one of many) in IE6 that forces you to pretty much never use that feature of CSS if you want one clean cross-browser CSS file.

The solution then is to use CSS classname prefixes to avoid colliding wiht generic classnames:

.area1 { ... }
.area1.area1Larger { ... }

.area2.area2Larger { ... }

May as well use just one class, but that way you can keep the CSS in the logic you intended, while knowing that .area1Larger only affects .area1, etc.

I made a simple tool that will display an image given a filename or image object or url.
It's crude, but it'll do in a hurry.

Installation:

 $ pip install simple-imshow

Usage:

from simshow import simshow
simshow('some_local_file.jpg')  # display from local file
simshow('http://mathandy.com/escher_sphere.png')  # display from url

I somehow stumbled on this clever hack on the internet ... I'm not sure if it's nasty or beautiful, but it lets you create a "magical" operator that allows you to unpack multiple return values into their own variable. The := function is defined here, and included below for posterity:

':=' <- function(lhs, rhs) {
  frame <- parent.frame()
  lhs <- as.list(substitute(lhs))
  if (length(lhs) > 1)
    lhs <- lhs[-1]
  if (length(lhs) == 1) {
    do.call(`=`, list(lhs[[1]], rhs), envir=frame)
    return(invisible(NULL)) 
  }
  if (is.function(rhs) || is(rhs, 'formula'))
    rhs <- list(rhs)
  if (length(lhs) > length(rhs))
    rhs <- c(rhs, rep(list(NULL), length(lhs) - length(rhs)))
  for (i in 1:length(lhs))
    do.call(`=`, list(lhs[[i]], rhs[[i]]), envir=frame)
  return(invisible(NULL)) 
}

With that in hand, you can do what you're after:

functionReturningTwoValues <- function() {
  return(list(1, matrix(0, 2, 2)))
}
c(a, b) := functionReturningTwoValues()
a
#[1] 1
b
#     [,1] [,2]
# [1,]    0    0
# [2,]    0    0

I don't know how I feel about that. Perhaps you might find it helpful in your interactive workspace. Using it to build (re-)usable libraries (for mass consumption) might not be the best idea, but I guess that's up to you.

... you know what they say about responsibility and power ...

What I do when I wonder something like the question asked here is go to the source.

toBe()

expect().toBe() is defined as:

function toBe() {
  return {
    compare: function(actual, expected) {
      return {
        pass: actual === expected
      };
    }
  };
}

It performs its test with === which means that when used as expect(foo).toBe(true), it will pass only if foo actually has the value true. Truthy values won't make the test pass.

toBeTruthy()

expect().toBeTruthy() is defined as:

function toBeTruthy() {
  return {
    compare: function(actual) {
      return {
        pass: !!actual
      };
    }
  };
}

Type coercion

A value is truthy if the coercion of this value to a boolean yields the value true. The operation !! tests for truthiness by coercing the value passed to expect to a boolean. Note that contrarily to what the currently accepted answer implies, == true is not a correct test for truthiness. You'll get funny things like

> "hello" == true
false
> "" == true
false
> [] == true
false
> [1, 2, 3] == true
false

Whereas using !! yields:

> !!"hello"
true
> !!""
false
> !![1, 2, 3]
true
> !![] 
true

(Yes, empty or not, an array is truthy.)

toBeTrue()

expect().toBeTrue() is part of Jasmine-Matchers (which is registered on npm as jasmine-expect after a later project registered jasmine-matchers first).

expect().toBeTrue() is defined as:

function toBeTrue(actual) {
  return actual === true ||
    is(actual, 'Boolean') &&
    actual.valueOf();
}

The difference with expect().toBeTrue() and expect().toBe(true) is that expect().toBeTrue() tests whether it is dealing with a Boolean object. expect(new Boolean(true)).toBe(true) would fail whereas expect(new Boolean(true)).toBeTrue() would pass. This is because of this funny thing:

> new Boolean(true) === true
false
> new Boolean(true) === false
false

At least it is truthy:

> !!new Boolean(true)
true

Which is best suited for use with elem.isDisplayed()?

Ultimately Protractor hands off this request to Selenium. The documentation states that the value produced by .isDisplayed() is a promise that resolves to a boolean. I would take it at face value and use .toBeTrue() or .toBe(true). If I found a case where the implementation returns truthy/falsy values, I would file a bug report.

Add a Button and on click of the Button add this code:

Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND); 
sharingIntent.setType("text/plain");
String shareBody = "Here is the share content body";
sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Subject Here");
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
startActivity(Intent.createChooser(sharingIntent, "Share via"));

For basic sharing

For customization

you can use console.log() to print object

console.log(my_object_array);

in case you have big object and want to print some of its values then you can use this custom function to print array in console

this.print = function (data,bpoint=0) {
    var c = 0;
    for(var k=0; k<data.length; k++){
        c++;
        console.log(c+'  '+data[k]);
        if(k!=0 && bpoint === k)break;  
    }
}

usage

print(array);   // to print entire obj array

or

print(array,50);  // 50 value to print only 

If you need it to work on both Mac and Windows, you can use QueryTables:

With ActiveSheet.QueryTables.Add(Connection:="URL;http://carbon.brighterplanet.com/flights.txt", Destination:=Range("A2"))
    .PostText = "origin_airport=MSN&destination_airport=ORD"
    .RefreshStyle = xlOverwriteCells
    .SaveData = True
    .Refresh
End With

Notes:

• Regarding output... I don't know if it's possible to return the results to the same cell that called the VBA function. In the example above, the result is written into A2.
• Regarding input... If you want the results to refresh when you change certain cells, make sure those cells are the argument to your VBA function.
• This won't work on Excel for Mac 2008, which doesn't have VBA. Excel for Mac 2011 got VBA back.

use xml.data["Data"][0].city instead

An optimized version of the implementation of the reverse function proposed by @michieljoris (according to the comments of @Beterraba and @Mala):

function a2hex(str) {_x000D_
  var hex = '';_x000D_
  for (var i = 0, l = str.length; i < l; i++) {_x000D_
    var hexx = Number(str.charCodeAt(i)).toString(16);_x000D_
    hex += (hexx.length > 1 && hexx || '0' + hexx);_x000D_
  }_x000D_
  return hex;_x000D_
}_x000D_
alert(a2hex('2460')); // display 32343630

I had the same problem, but in c# 2012 I closed the "report data" and I couldn't find it and I finally found a solution to this issue.

This is my method:

VIEW >> TOOLBARS >> CUSTOMIZE >> COMMANDS ... select from the "Menu bar" .. VIEW.

OK now in the "Controls" find the "REPORT DATA", select it and MOVE it UP, close the menu. After that select a file.rdlc and click on the "View" ... OK Finally will be appeared "REPORT DATA"...

I think the easiest way is the following steps, you won't need to install any package or software:

1. First, you find out the GID of the group that you want to know the users, there are a lot of ways for that: cat /etc/group (the last column is the GID) id user (the user is someone who belongs to the group)

2. Now you will list all the user on the file /etc/passwd, but you will apply some filters with the following sequel of commands to get just the members of the previous group.

cut -d: -f1,4 /etc/passwd |grep GID (the GID is the number you got from the step 1)

cut command will select just some "columns" of the file, the parameter d sets the delimiter ":" in this case, the parameter -f selects the "fields" (or columns) to be shown 1 and 4 in out case (on the file /etc/passwd, the 1º column is the name of the user and the 4º is the GID of the group which the user belongs), to finalize the |grep GID will filter just the group (on the 4º column) that you had chosen.

ULs don't have a name attribute, but you can reference the ul by tag name.

Try replacing line 3 in your script with this:

var sub = cat.getElementsByTagName("UL");

Here's an example that makes sure that the body has minimum height of the device screen height and also hides the scroll bar. It uses DOMSubtreeModified event, but makes the check only every 400ms, to avoid performance loss.

var page_size_check = null, q_body;
(q_body = $('#body')).bind('DOMSubtreeModified', function() {
  if (page_size_check === null) {
    return;
  }
  page_size_check = setTimeout(function() {
    q_body.css('height', '');
    if (q_body.height() < window.innerHeight) {
      q_body.css('height', window.innerHeight + 'px');
    }
    if (!(window.pageYOffset > 1)) {
      window.scrollTo(0, 1);
    }
    page_size_check = null;
  }, 400);
});

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

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

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

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

I believe that should do it.

Add to your settings.py:

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'handlers': {
        'file': {
            'level': 'DEBUG',
            'class': 'logging.FileHandler',
            'filename': 'debug.log',
        },
    },
    'loggers': {
        'django': {
            'handlers': ['file'],
            'level': 'DEBUG',
            'propagate': True,
        },
    },
}

And it will create a file called debug.log in the root of your. https://docs.djangoproject.com/en/1.10/topics/logging/

Visual Studio Code:

Delete the files from your Explorer view. You see them crossed-out in your Branch view. Then commit and Sync.

Be aware: If files are on your .gitignore list, then the delete "update" will not be pushed and therefore not be visible. VS Code will warn you if this is the case, though. -> Exclude the files/folder from gitignore temporarily.

Here is couple of ways to calculate length of variable :

echo ${#VAR}
echo -n $VAR | wc -m
echo -n $VAR | wc -c
printf $VAR | wc -m
expr length $VAR
expr $VAR : '.*'

and to set the result in another variable just assign above command with back quote into another variable as following:

otherVar=`echo -n $VAR | wc -m`   
echo $otherVar

I've been searching through all the examples and answers of how to pass any array to sql server without the hassle of creating new Table type,till i found this linK, below is how I applied it to my project:

--The following code is going to get an Array as Parameter and insert the values of that --array into another table

Create Procedure Proc1 


@UserId int, //just an Id param
@s nvarchar(max)  //this is the array your going to pass from C# code to your Sproc

AS

    declare @xml xml

    set @xml = N'<root><r>' + replace(@s,',','</r><r>') + '</r></root>'

    Insert into UserRole (UserID,RoleID)
    select 
       @UserId [UserId], t.value('.','varchar(max)') as [RoleId]


    from @xml.nodes('//root/r') as a(t)
END

The error you are getting is either because you are doing TO_DATE on a column that's already a date, and you're using a format mask that is different to your nls_date_format parameter[1] or because the event_occurrence column contains data that isn't a number.

You need to a) correct your query so that it's not using TO_DATE on the date column, and b) correct your data, if event_occurrence is supposed to be just numbers.

And fix the datatype of that column to make sure you can only store numbers.

[1] What Oracle does when you do: TO_DATE(date_column, non_default_format_mask) is: TO_DATE(TO_CHAR(date_column, nls_date_format), non_default_format_mask)

Generally, the default nls_date_format parameter is set to dd-MON-yy, so in your query, what is likely to be happening is your date column is converted to a string in the format dd-MON-yy, and you're then turning it back to a date using the format MMDD. The string is not in this format, so you get an error.

A working example.

DECLARE @TableName AS VARCHAR(100)
SELECT @TableName = 'YourTableName'

EXECUTE ('SELECT * INTO #TEMP  FROM ' + @TableName +'; SELECT * FROM #TEMP;')

Second solution with accessible temp table

DECLARE @TableName AS VARCHAR(100)
SELECT @TableName = 'YOUR_TABLE_NAME'

EXECUTE ('CREATE VIEW vTemp AS
        SELECT *
        FROM ' + @TableName)
SELECT * INTO #TEMP  FROM vTemp 

--DROP THE VIEW HERE      
DROP VIEW vTemp

/*START USING TEMP TABLE
************************/
--EX:
SELECT * FROM #TEMP


--DROP YOUR TEMP TABLE HERE
DROP TABLE #TEMP

Everyone here is correct, but I think it fails to address the "when". First, from Design Patterns:

Visitor lets you define a new operation without changing the classes of the elements on which it operates.

Now, let's think of a simple class hierarchy. I have classes 1, 2, 3 and 4 and methods A, B, C and D. Lay them out like in a spreadsheet: the classes are lines and the methods are columns.

Now, Object Oriented design presumes you are more likely to grow new classes than new methods, so adding more lines, so to speak, is easier. You just add a new class, specify what's different in that class, and inherits the rest.

Sometimes, though, the classes are relatively static, but you need to add more methods frequently -- adding columns. The standard way in an OO design would be to add such methods to all classes, which can be costly. The Visitor pattern makes this easy.

By the way, this is the problem that Scala's pattern matches intends to solve.

Arrays in PHP are associative arrays (otherwise known as dictionaries or hashes) by default. If you don't explicitly assign a key to a value, the interpreter will silently do that for you. So, the expression you've got up there iterates through $user_list, making the key available as $user and the value available as $pass as local variables in the body of the foreach.

every minute:

* * * * * /path/to/php /var/www/html/a.php

every 24hours (every midnight):

0 0 * * * /path/to/php /var/www/html/reset.php

Use git revert like so:

git revert <insert bad commit hash here>

git revert creates a new commit with the changes that are rolled back. git reset erases your git history instead of making a new commit.

The steps after are the same as any other commit.

Inline Functions

In C++ a macro is nothing but inline function. SO now macros are under control of compiler.

• Important : If we define a function inside class it will become Inline automatically

Code of Inline function is replaced at the place it is called, so it reduce the overhead of calling function.

In some cases Inlining of function can not work, Such as

• If static variable used inside inline function.

• If function is complicated.

• If recursive call of function

• If address of function taken implicitely or explicitely

Function defined outside class as below may become inline

inline int AddTwoVar(int x,int y); //This may not become inline 

inline int AddTwoVar(int x,int y) { return x + y; } // This becomes inline

Function defined inside class also become inline

// Inline SpeedMeter functions
class SpeedMeter
{
    int speed;
    public:
    int getSpeed() const { return speed; }
    void setSpeed(int varSpeed) { speed = varSpeed; }
};
int main()
{
    SpeedMeter objSM;
    objSM.setSpeed(80);
    int speedValue = A.getSpeed();
} 

Here both getSpeed and setSpeed functions will become inline

Here's a possible way to do it:

$string=exec('getmac');
$mac=substr($string, 0, 17); 
echo $mac;

I use this

this.$refs['refFormName'].resetFields();

this work fine for me.

You can maybe do something like this with awk

awk '{outfile=sprintf("file%02d.txt",NR/5000+1);print > outfile}' yourfile

Basically, it calculates the name of the output file by taking the record number (NR) and dividing it by 5000, adding 1, taking the integer of that and zero-padding to 2 places.

By default, awk prints the entire input record when you don't specify anything else. So, print > outfile writes the entire input record to the output file.

As you are running on Windows, you can't use single quotes because it doesn't like that. I think you have to put the script in a file and then tell awkto use the file, something like this:

awk -f script.awk yourfile

and script.awk will contain the script like this:

{outfile=sprintf("file%02d.txt",NR/5000+1);print > outfile}

Or, it may work if you do this:

awk "{outfile=sprintf(\"file%02d.txt\",NR/5000+1);print > outfile}" yourfile

Backup over ssh with password using temporary .pgpass credentials and push to S3:

#!/usr/bin/env bash
cd "$(dirname "$0")"

DB_HOST="*******.*********.us-west-2.rds.amazonaws.com"
DB_USER="*******"
SSH_HOST="[email protected]_domain.com"
BUCKET_PATH="bucket_name/backup"

if [ $# -ne 2 ]; then
    echo "Error: 2 arguments required"
    echo "Usage:"
    echo "  my-backup-script.sh <DB-name> <password>"
    echo "  <DB-name> = The name of the DB to backup"
    echo "  <password> = The DB password, which is also used for GPG encryption of the backup file"
    echo "Example:"
    echo "  my-backup-script.sh my_db my_password"
    exit 1
fi

DATABASE=$1
PASSWORD=$2

echo "set remote PG password .."
echo "$DB_HOST:5432:$DATABASE:$DB_USER:$PASSWORD" | ssh "$SSH_HOST" "cat > ~/.pgpass; chmod 0600 ~/.pgpass"
echo "backup over SSH and gzip the backup .."
ssh "$SSH_HOST" "pg_dump -U $DB_USER -h $DB_HOST -C --column-inserts $DATABASE" | gzip > ./tmp.gz
echo "unset remote PG password .."
echo "*********" | ssh "$SSH_HOST" "cat > ~/.pgpass"
echo "encrypt the backup .."
gpg --batch --passphrase "$PASSWORD" --cipher-algo AES256 --compression-algo BZIP2 -co "$DATABASE.sql.gz.gpg" ./tmp.gz

# Backing up to AWS obviously requires having your credentials to be set locally
# EC2 instances can use instance permissions to push files to S3
DATETIME=`date "+%Y%m%d-%H%M%S"`
aws s3 cp ./"$DATABASE.sql.gz.gpg" s3://"$BUCKET_PATH"/"$DATABASE"/db/"$DATETIME".sql.gz.gpg
# s3 is cheap, so don't worry about a little temporary duplication here
# "latest" is always good to have because it makes it easier for dev-ops to use
aws s3 cp ./"$DATABASE.sql.gz.gpg" s3://"$BUCKET_PATH"/"$DATABASE"/db/latest.sql.gz.gpg

echo "local clean-up .."
rm ./tmp.gz
rm "$DATABASE.sql.gz.gpg"

echo "-----------------------"
echo "To decrypt and extract:"
echo "-----------------------"
echo "gpg -d ./$DATABASE.sql.gz.gpg | gunzip > tmp.sql"
echo

Just substitute the first couple of config lines with whatever you need - obviously. For those not interested in the S3 backup part, take it out - obviously.

This script deletes the credentials in .pgpass afterward because in some environments, the default SSH user can sudo without a password, for example an EC2 instance with the ubuntu user, so using .pgpass with a different host account in order to secure those credential, might be pointless.

We recently had to find the current x,y position to enumerate elements over which the cursor is hovering independent of z-index. We ended up just attaching a mousemove event listener to document e.g.,

function findElements(e) {
  var els = document.elementsFromPoint(e.clientX, e.clientY);

  // do cool stuff with els
  console.log(els);

  return;
}

document.addEventListener("mousemove", findElements);

I like Dan's answer, esp because of the avoidance of exceptions. For embedded systems development and other low level system development, there may not be a proper Exception framework available.

Added a check for white-space after a valid string...these three lines

    while (isspace(*end)) {
        end++;
    }

Added a check for parsing errors too.

    if ((errno != 0) || (s == end)) {
        return INCONVERTIBLE;
    }

Here is the complete function..

#include <cstdlib>
#include <cerrno>
#include <climits>
#include <stdexcept>

enum STR2INT_ERROR { SUCCESS, OVERFLOW, UNDERFLOW, INCONVERTIBLE };

STR2INT_ERROR str2long (long &l, char const *s, int base = 0)
{
    char *end = (char *)s;
    errno = 0;

    l = strtol(s, &end, base);

    if ((errno == ERANGE) && (l == LONG_MAX)) {
        return OVERFLOW;
    }
    if ((errno == ERANGE) && (l == LONG_MIN)) {
        return UNDERFLOW;
    }
    if ((errno != 0) || (s == end)) {
        return INCONVERTIBLE;
    }    
    while (isspace((unsigned char)*end)) {
        end++;
    }

    if (*s == '\0' || *end != '\0') {
        return INCONVERTIBLE;
    }

    return SUCCESS;
}

maybe you could use AsyncStorage setItem and getItem...and store the data as string, then use the json parser for convert it again to json...

To change the end address property edit your wsdl file

<wsdl:definitions.......
  <wsdl:service name="serviceMethodName">
    <wsdl:port binding="tns:serviceMethodNameSoapBinding" name="serviceMethodName">

    </wsdl:port>
  </wsdl:service>

This will print duplicate lines only, with counts:

sort FILE | uniq -cd

or, with GNU long options (on Linux):

sort FILE | uniq --count --repeated

on BSD and OSX you have to use grep to filter out unique lines:

sort FILE | uniq -c | grep -v '^ *1 '

For the given example, the result would be:

  3 123
  2 234

If you want to print counts for all lines including those that appear only once:

sort FILE | uniq -c

or, with GNU long options (on Linux):

sort FILE | uniq --count

For the given input, the output is:

  3 123
  2 234
  1 345

In order to sort the output with the most frequent lines on top, you can do the following (to get all results):

sort FILE | uniq -c | sort -nr

or, to get only duplicate lines, most frequent first:

sort FILE | uniq -cd | sort -nr

on OSX and BSD the final one becomes:

sort FILE | uniq -c | grep -v '^ *1 ' | sort -nr

The following code get the first day of January of current year (but it can be a another date) and add 365 days to that day (but it can be N number of days) using DateTime class and its method modify() and format():

echo (new DateTime((new DateTime())->modify('first day of January this year')->format('Y-m-d')))->modify('+365 days')->format('Y-m-d');

How about just using:

result = [VLOOKUP(DATA!AN2, DATA!AA9:AF20, 5, FALSE)]

Note the [ and ].

The trick is to give padding on the td elements, but make an exception for the first (yes, it's hacky, but sometimes you have to play by the browser's rules):

td {
  padding-top:20px;
  padding-bottom:20px;
  padding-right:20px;   
}

td:first-child {
  padding-left:20px;
  padding-right:0;
}

First-child is relatively well supported: https://developer.mozilla.org/en-US/docs/CSS/:first-child

You can use the same reasoning for the horizontal padding by using tr:first-child td.

Alternatively, exclude the first column by using the not operator. Support for this is not as good right now, though.

td:not(:first-child) {
  padding-top:20px;
  padding-bottom:20px;
  padding-right:20px;       
}

This answer is based on the question and title of this book: http://www.packtpub.com/angularjs-web-application-development/book

In your own answer, you effectively do this:

Dim SrcRange As Range ' you should always declare things explicitly
Set SrcRange = Sheets("Src").Range("A2:A9")
SrcRange.Copy Destination:=Sheets("Dest").Range("A2")

You're not really "extracting" the range to a variable, you're setting a reference to the range.

In many situations, this can be more efficient as well as more flexible:

Dim Src As Variant
Src= Sheets("Src").Range("A2:A9").Value 'Read range to array
'Here you can add code to manipulate your Src array
'...
Sheets("Dest").Range("A2:A9").Value = Src 'Write array back to another range

For me, it came down to the proxy_pass location setting. I needed to change over to using the HTTPS protocol, and have a valid SSL certificate set up on the node server side of things. That way when I introduce an external node server, I only have to change the IP and everything else remains the same config.

I hope this helps someone along the way... I was staring at the problem the whole time... sigh...

In order to use php in .html files, you must associate them with your PHP processor in your HTTP server's config file. In Apache, that looks like this:

AddHandler application/x-httpd-php .html

For several cases, or even just a few cases involving a lot of criteria, consider using a switch.

switch( true ){

    case ( !empty($youtube) && !empty($link) ):{
        // Nothing is empty...
        break;
    }

    case ( !empty($youtube) && empty($link) ):{
        // One is empty...
        break;
    }

    case ( empty($youtube) && !empty($link) ):{
        // The other is empty...
        break;
    }

    case ( empty($youtube) && empty($link) ):{
        // Everything is empty
        break;
    }

    default:{
        // Even if you don't expect ever to use it, it's a good idea to ALWAYS have a default.
        // That way if you change it, or miss a case, you have some default handler.
        break;
    }

}

If you have multiple cases that require the same action, you can stack them and omit the break; to flowthrough. Just maybe put a comment like /*Flowing through*/ so you're explicit about doing it on purpose.

Note that the { } around the cases aren't required, but they are nice for readability and code folding.

More about switch: http://php.net/manual/en/control-structures.switch.php

Values like M_PI, M_PI_2, M_PI_4, etc are not standard C++ so a constexpr seems a better solution. Different const expressions can be formulated that calculate the same pi and it concerns me whether they (all) provide me the full accuracy. The C++ standard does not explicitly mention how to calculate pi. Therefore, I tend to fall back to defining pi manually. I would like to share the solution below which supports all kind of fractions of pi in full accuracy.

#include <ratio>
#include <iostream>

template<typename RATIO>
constexpr double dpipart()
{
    long double const pi = 3.14159265358979323846264338327950288419716939937510582097494459230781640628620899863;
    return static_cast<double>(pi * RATIO::num / RATIO::den);
}

int main()
{
    std::cout << dpipart<std::ratio<-1, 6>>() << std::endl;
}

Allocate maximum memory to your docker machine from (docker preference -> advance )

Screenshot of advance settings:

This will set the maximum limit docker consume while running containers. Now run your image in new container with -m=4g flag for 4 gigs ram or more. e.g.

docker run -m=4g {imageID}

Remember to apply the ram limit increase changes. Restart the docker and double check that ram limit did increased. This can be one of the factor you not see the ram limit increase in docker containers.

You can cast a method group into a delegate.

The delegate signature selects 1 method out of the group.

This example picks the ToString() overload which takes a string parameter:

Func<string,string> fn = 123.ToString;
Console.WriteLine(fn("00000000"));

This example picks the ToString() overload which takes no parameters:

Func<string> fn = 123.ToString;
Console.WriteLine(fn());

I found another working solution: add the following line to your app under the onCreate event.

getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

My sample Cordova project looks like this:

package com.apps.demo;
import android.os.Bundle;
import android.view.WindowManager;
import org.apache.cordova.*;

public class ScanManActivity extends DroidGap {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
        super.loadUrl("http://stackoverflow.com");
    }
}

After that, my app would not go to sleep while it was open. Thanks for the anwer goes to xSus.

To my knowledge, you cannot disable the browser window.

What you can do is create a jQuery (or a similar kind of ) popup and when this popup appears your parent browser will be disabled.

Open your child page in popup.

Your compiler is right. You can't use the growthRate variable you declared in main as a function.

Maybe you should pick different names for your variables so they don't override function names?

This is a little outdated, by Ryan Bigg does a great job explaining this here:

http://ryanbigg.com/2009/04/how-rails-works-2-mime-types-respond_to

In fact, it might be a bit more detail than you were looking for. As it turns out, there's a lot going on behind the scenes, including a need to understand how the MIME types get loaded.

You can also see this information by going into Admin Console -> Realm Settings -> Clicking the hyperlink on the Endpoints field.

2 Extension methods for the solutions mentioned above

    public static bool LiesAfterIgnoringMilliseconds(this DateTime theDate, DateTime compareDate, DateTimeKind kind)
    {
        DateTime thisDate = new DateTime(theDate.Year, theDate.Month, theDate.Day, theDate.Hour, theDate.Minute, theDate.Second, kind);
        compareDate = new DateTime(compareDate.Year, compareDate.Month, compareDate.Day, compareDate.Hour, compareDate.Minute, compareDate.Second, kind);

        return thisDate > compareDate;
    }


    public static bool LiesAfterOrEqualsIgnoringMilliseconds(this DateTime theDate, DateTime compareDate, DateTimeKind kind)
    {
        DateTime thisDate = new DateTime(theDate.Year, theDate.Month, theDate.Day, theDate.Hour, theDate.Minute, theDate.Second, kind);
        compareDate = new DateTime(compareDate.Year, compareDate.Month, compareDate.Day, compareDate.Hour, compareDate.Minute, compareDate.Second, kind);

        return thisDate >= compareDate;
    }

usage:

bool liesAfter = myObject.DateProperty.LiesAfterOrEqualsIgnoringMilliseconds(startDateTime, DateTimeKind.Utc);

For me, I set two times:

(MimeBodyPart)messageBodyPart.setContent(content, text/html)
(Multipart)multipart.addBodyPart(messageBodyPart)
(MimeMessage)msg.setContent(multipart, text/html)

and its been working fine.

Do you mean altering the table after it has been created? If so you need to use alter table, in particular:

ALTER TABLE tablename MODIFY COLUMN new-column-definition

e.g.

ALTER TABLE test MODIFY COLUMN locationExpect VARCHAR(120);

Here's a data.table solution that will list the duplicates along with the number of duplications (will be 1 if there are 2 copies, and so on - you can adjust that to suit your needs):

library(data.table)
dt = data.table(vocabulary)

dt[duplicated(id), cbind(.SD[1], number = .N), by = id]

It is not possible to get the users computer name with Javascript. You can get all details about the browser and network. But not more than that.

Like some one answered in one of the previous question today.

I already did a favor of visiting your website, May be I will return or refer other friends.. I also told you where I am and what OS, Browser and screen resolution I use Why do you want to know the color of my underwear? ;-)

You cannot do it using asp.net as well.

Try this:

RewriteCond %{HTTP_HOST} ^www\. [NC]
RewriteRule ^(.*)$ %{HTTP_HOST}$1 [C]
RewriteRule ^www\.(.*)$ http://$1 [L,R=301]

If the host starts with www, we stick the whole host onto the start of the URL, then take off the "www."

Use this html to get the clicked element:

<div class="row" style="padding-left:21px;">
    <ul class="nav nav-tabs" style="padding-left:40px;">
        <li class="active filter"><a href="#month" onclick="Data('month', this)">This Month</a></li>
        <li class="filter"><a href="#year" onclick="Data('year', this)">Year</a></li>
        <li class="filter"><a href="#last60" onclick="Data('last60', this)">60 Days</a></li>
        <li class="filter"><a href="#last90" onclick="Data('last90', this)">90 Days</a></li>
    </ul> 
</div>

Script:

 function Data(string, el)
 {
     $('.filter').removeClass('active');
     $(el).parent().addClass('active');
 } 

Braintree also has an open source PHP library that makes PHP integration pretty easy.

I resolved by replacing the corrupted jar files.

But to find those corrupted jar files, I have to run my application in three IDE- 1) Intellij Idea 2)NetBeans 3) Eclipse.

Netbeans given me information for maximum number of corrupted jar. In Netbeans along with the run, I use the build option(after right clicking on project) to know more about corrupted jars.

It took me more than 15 hours to find out the root cause for these errors. Hope it help anyone.

You can do something like this:

    public myform()
    {
         InitializeComponent(); // this will be called in ComboBox ComboBox = new System.Windows.Forms.ComboBox();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        // TODO: This line of code loads data into the 'myDataSet.someTable' table. You can move, or remove it, as needed.
        this.myTableAdapter.Fill(this.myDataSet.someTable);
        comboBox1.SelectedItem = null;
        comboBox1.SelectedText = "--select--";           
    }

Some other service may be using port 80: try to stop the other services: HTTPD, SSL, NGINX, PHP, with the command sudo systemctl stop and then use the command sudo systemctl start httpd

You can use it with your local variables, like this:

@animal = "Dog"
@action = "licks"
@second_animal = "Bird"

"The #{@animal} #{@action} the #{@second_animal}"

the output would be: "The Dog licks the Bird"

I was facing with this problem some time ago and I found java.util.LinkedList is best for my case. It has several methods, with different namings, but they're doing what is needed:

push()    -> LinkedList.addLast(); // Or just LinkedList.add();
pop()     -> LinkedList.pollLast();
shift()   -> LinkedList.pollFirst();
unshift() -> LinkedList.addFirst();

The python 2.5 documentation explains it well.

Tuples and lists are compared lexicographically using comparison of corresponding elements. This means that to compare equal, each element must compare equal and the two sequences must be of the same type and have the same length.

If not equal, the sequences are ordered the same as their first differing elements. For example, cmp([1,2,x], [1,2,y]) returns the same as cmp(x,y). If the corresponding element does not exist, the shorter sequence is ordered first (for example, [1,2] < [1,2,3]).

Unfortunately that page seems to have disappeared in the documentation for more recent versions.

For general check if there was a POST action use:

if (!empty($_POST))

EDIT: As stated in the comments, this method won't work for in some cases (e.g. with check boxes and button without a name). You really should use:

if ($_SERVER['REQUEST_METHOD'] == 'POST')

Sets require their items to be hashable. Out of types predefined by Python only the immutable ones, such as strings, numbers, and tuples, are hashable. Mutable types, such as lists and dicts, are not hashable because a change of their contents would change the hash and break the lookup code.

Since you're sorting the list anyway, just place the duplicate removal after the list is already sorted. This is easy to implement, doesn't increase algorithmic complexity of the operation, and doesn't require changing sublists to tuples:

def uniq(lst):
    last = object()
    for item in lst:
        if item == last:
            continue
        yield item
        last = item

def sort_and_deduplicate(l):
    return list(uniq(sorted(l, reverse=True)))

I only have the need to push files during a build, so I just added a Post-build Event Command Line entry like this:

Copy /Y "$(SolutionDir)Third Party\SomeLibrary\*" "$(TargetDir)"

You can set this by right-clicking your Project in the Solution Explorer, then Properties > Build Events

I had a similar problem when trying to operate on a rooted Samsung Galaxy S. Issuing a command from the computer shell

> adb root

fails with a message "cannot run as root in production builds". Here is a simple method that allows to become root.

Instead of the previous, issue the following two commands one after the other

> adb shell
$ su

After the first command, if the prompt has changed from '>' to '$' as shown above, it means that you have entered the adb shell environment. If subsequently the prompt has changed to '#' after issuing the second command, that means that you are now root. Now, as root, you can do anything you want with your device.

To switch back to 'safe' shell, issue

# exit

You will see that the prompt '$' reappears which means you are in the adb shell as a user and not as root.

Not really.

Depending on what you actually need, one possibility may be to set o as the prototype of a new object.

var o = {};
(function(x){
    var obj = Object.create( x );
    obj.foo = 'foo';
    obj.bar = 'bar';
})(o);

alert( o.foo ); // undefined

So any properties you add to obj will be not be added to o. Any properties added to obj with the same property name as a property in o will shadow the o property.

Of course, any properties added to o will be available from obj if they're not shadowed, and all objects that have o in the prototype chain will see the same updates to o.

Also, if obj has a property that references another object, like an Array, you'll need to be sure to shadow that object before adding members to the object, otherwise, those members will be added to obj, and will be shared among all objects that have obj in the prototype chain.

var o = {
    baz: []
};
(function(x){
    var obj = Object.create( x );

    obj.baz.push( 'new value' );

})(o);

alert( o.baz[0] );  // 'new_value'

Here you can see that because you didn't shadow the Array at baz on o with a baz property on obj, the o.baz Array gets modified.

So instead, you'd need to shadow it first:

var o = {
    baz: []
};
(function(x){
    var obj = Object.create( x );

    obj.baz = [];
    obj.baz.push( 'new value' );

})(o);

alert( o.baz[0] );  // undefined

Here is the solution for Rest API

class Program
{
    static void Main(string[] args)
    {
        BaseClient clientbase = new BaseClient("https://website.com/api/v2/", "username", "password");
        BaseResponse response = new BaseResponse();
        BaseResponse response = clientbase.GetCallV2Async("Candidate").Result;
    }


    public async Task<BaseResponse> GetCallAsync(string endpoint)
    {
        try
        {
            HttpResponseMessage response = await client.GetAsync(endpoint + "/").ConfigureAwait(false);
            if (response.IsSuccessStatusCode)
            {
                baseresponse.ResponseMessage = await response.Content.ReadAsStringAsync();
                baseresponse.StatusCode = (int)response.StatusCode;
            }
            else
            {
                baseresponse.ResponseMessage = await response.Content.ReadAsStringAsync();
                baseresponse.StatusCode = (int)response.StatusCode;
            }
            return baseresponse;
        }
        catch (Exception ex)
        {
            baseresponse.StatusCode = 0;
            baseresponse.ResponseMessage = (ex.Message ?? ex.InnerException.ToString());
        }
        return baseresponse;
    }
}


public class BaseResponse
{
    public int StatusCode { get; set; }
    public string ResponseMessage { get; set; }
}

public class BaseClient
{
    readonly HttpClient client;
    readonly BaseResponse baseresponse;

    public BaseClient(string baseAddress, string username, string password)
    {
        HttpClientHandler handler = new HttpClientHandler()
        {
            Proxy = new WebProxy("http://127.0.0.1:8888"),
            UseProxy = false,
        };

        client = new HttpClient(handler);
        client.BaseAddress = new Uri(baseAddress);
        client.DefaultRequestHeaders.Accept.Clear();
        client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
        var byteArray = Encoding.ASCII.GetBytes(username + ":" + password);

        client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", Convert.ToBase64String(byteArray));

        baseresponse = new BaseResponse();

    }
}

This does exist, but it's actually a feature of git log:

git log -p [--follow] [-1] <path>

Note that -p can also be used to show the inline diff from a single commit:

git log -p -1 <commit>

Options used:

• -p (also -u or --patch) is hidden deeeeeeeep in the git-log man page, and is actually a display option for git-diff. When used with log, it shows the patch that would be generated for each commit, along with the commit information—and hides commits that do not touch the specified <path>. (This behavior is described in the paragraph on --full-diff, which causes the full diff of each commit to be shown.)
• -1 shows just the most recent change to the specified file (-n 1 can be used instead of -1); otherwise, all non-zero diffs of that file are shown.
• --follow is required to see changes that occurred prior to a rename.

As far as I can tell, this is the only way to immediately see the last set of changes made to a file without using git log (or similar) to either count the number of intervening revisions or determine the hash of the commit.

To see older revisions changes, just scroll through the log, or specify a commit or tag from which to start the log. (Of course, specifying a commit or tag returns you to the original problem of figuring out what the correct commit or tag is.)

Credit where credit is due:

• I discovered log -p thanks to this answer.
• Credit to FranciscoPuga and this answer for showing me the --follow option.
• Credit to ChrisBetti for mentioning the -n 1 option and atatko for mentioning the -1 variant.
• Credit to sweaver2112 for getting me to actually read the documentation and figure out what -p "means" semantically.

You can simply open the phpmyadmin page from your browser, then open any existing database -> go to Privileges tab, click on your root user and then a popup window will appear, you can set your password there.. Hope this Helps.

Question is old, but it's never too late to answer.

$(document).ready(function() {
  //prevent drag and drop
  const yourInput = document.getElementById('inputid');
  yourInput.ondrop = e => e.preventDefault();

  //prevent paste
  const Input = document.getElementById('inputid');
  Input.onpaste = e => e.preventDefault();
});

I honestly doubt it, for a number of reasons, but the most important one is that there are some instructions that are allowed in 32-bit mode, but not in 64-bit mode. Specifically, the REX prefix that is used to encode some instructions and registers in 64-bit mode is a byte of the form 0x4f:0x40, but in 32 bit mode the same byte is either INC or DEC with a fixed operand.
Because of this, any 64-bit instruction that is prefixed by REX will be interpreted as either INC or DEC, and won't give the VMM the chance to emulate the 64-bit instruction (for instance by signaling an undefined opcode exception).

The only way it might be done is to use a trap exception to return to the VMM after each and every instruction so that it can see if it needs special 64-bit handling. I simply can't see that happening.

Warning This method will not work beyond 5.0, it was a quite dated entry.

Use the class below to change/check the Wifi hotspot setting:

import android.content.*;
import android.net.wifi.*;
import java.lang.reflect.*;

public class ApManager {

//check whether wifi hotspot on or off
public static boolean isApOn(Context context) {
    WifiManager wifimanager = (WifiManager) context.getSystemService(context.WIFI_SERVICE);     
    try {
        Method method = wifimanager.getClass().getDeclaredMethod("isWifiApEnabled");
        method.setAccessible(true);
        return (Boolean) method.invoke(wifimanager);
    }
    catch (Throwable ignored) {}
    return false;
}

// toggle wifi hotspot on or off
public static boolean configApState(Context context) {
    WifiManager wifimanager = (WifiManager) context.getSystemService(context.WIFI_SERVICE);
    WifiConfiguration wificonfiguration = null;
    try {  
        // if WiFi is on, turn it off
        if(isApOn(context)) {               
            wifimanager.setWifiEnabled(false);
        }               
        Method method = wifimanager.getClass().getMethod("setWifiApEnabled", WifiConfiguration.class, boolean.class);

    } 
    catch (Exception e) {
        e.printStackTrace();
    }       
    return false;

You need to add the permissions below to your AndroidMainfest:

<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

Use this standalone ApManager class from anywhere as follows:

ApManager.isApOn(YourActivity.this); // check Ap state :boolean
ApManager.configApState(YourActivity.this); // change Ap state :boolean

Hope this will help someone

Hit enter as there is no password. Enter the following commands:

mysql> SET PASSWORD for 'root'@'localhost' = password('enteryourpassword');
mysql> SET PASSWORD for 'root'@'127.0.0.1' = password('enteryourpassword');
mysql> SET PASSWORD for 'root'@'::1' = password('enteryourpassword');

That’s it, I keep the passwords the same to keep things simple. If you want to check the user’s table to see that the info has been updated just enter the additional commands as shown below. This is a good option to check that you have indeed entered the same password for all hosts.

Just found a post Atomic vs. Non-Atomic Operations to be very helpful to me.

"An operation acting on shared memory is atomic if it completes in a single step relative to other threads.

When an atomic store is performed on a shared memory, no other thread can observe the modification half-complete.

When an atomic load is performed on a shared variable, it reads the entire value as it appeared at a single moment in time."

Not sure why Matthew's solution didn't work for me (could be that I'm using OSX10.8 or perhaps something to do with macports). But I added the following to the end of the file at ~/.profile

export PYTHONPATH=/path/to/dir:$PYTHONPATH

my directory is now on the pythonpath -

my-macbook:~ aidan$ python
Python 2.7.2 (default, Jun 20 2012, 16:23:33) 
[GCC 4.2.1 Compatible Apple Clang 4.0 (tags/Apple/clang-418.0.60)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.path
['', '/path/to/dir', ...  

and I can import modules from that directory.

If this can't be wrapped with generics (@Martijn's answer) it's better to pass it without casting to avoid redundant list iteration (checking the first element's type guarantees nothing). We can cast each element in the piece of code where we iterate the list.

Object attVal = jsonMap.get("attName");
List<Object> ls = new ArrayList<>();
if (attVal instanceof List) {
    ls.addAll((List) attVal);
} else {
    ls.add(attVal);
}

// far, far away ;)
for (Object item : ls) {
    if (item instanceof String) {
        System.out.println(item);
    } else {
        throw new RuntimeException("Wrong class ("+item .getClass()+") of "+item );
    }
}

Assert.Throws returns the exception that's thrown which lets you assert on the exception.

var ex = Assert.Throws<Exception>(() => user.MakeUserActive());
Assert.That(ex.Message, Is.EqualTo("Actual exception message"));

So if no exception is thrown, or an exception of the wrong type is thrown, the first Assert.Throws assertion will fail. However if an exception of the correct type is thrown then you can now assert on the actual exception that you've saved in the variable.

By using this pattern you can assert on other things than the exception message, e.g. in the case of ArgumentException and derivatives, you can assert that the parameter name is correct:

var ex = Assert.Throws<ArgumentNullException>(() => foo.Bar(null));
Assert.That(ex.ParamName, Is.EqualTo("bar"));

You can also use the fluent API for doing these asserts:

Assert.That(() => foo.Bar(null), 
Throws.Exception
  .TypeOf<ArgumentNullException>()
  .With.Property("ParamName")
  .EqualTo("bar"));

or alternatively

Assert.That(
    Assert.Throws<ArgumentNullException>(() =>
        foo.Bar(null)
    .ParamName,
Is.EqualTo("bar"));

A little tip when asserting on exception messages is to decorate the test method with the SetCultureAttribute to make sure that the thrown message is using the expected culture. This comes into play if you store your exception messages as resources to allow for localization.

Collations affect how data is sorted and how strings are compared to each other. That means you should use the collation that most of your users expect.

Example from the documentation for charset unicode:

utf8_general_ci also is satisfactory for both German and French, except that ‘ß’ is equal to ‘s’, and not to ‘ss’. If this is acceptable for your application, then you should use utf8_general_ci because it is faster. Otherwise, use utf8_unicode_ci because it is more accurate.

So - it depends on your expected user base and on how much you need correct sorting. For an English user base, utf8_general_ci should suffice, for other languages, like Swedish, special collations have been created.

you can use this one in onCreateView, you can use transaction or replace

 OnBackPressedCallback callback = new OnBackPressedCallback(true) {
                @Override
                public void handleOnBackPressed() {
                    //what you want to do 
                }
            };
    requireActivity().getOnBackPressedDispatcher().addCallback(this, callback);

To add to wflynny's answer above, you can find the available colormaps here

Example:

import matplotlib.cm as cm
plt.scatter(x, y, c=t, cmap=cm.jet)

or alternatively,

plt.scatter(x, y, c=t, cmap='jet')

Make sure when you create a txt file you don't type in the name "name.txt", just type in "name". If you type "name.txt" Eclipse will see it as "name.txt.txt". This solved it for me. Also save the file in the src folder, not the folder were the .java resides, one folder up.

Use LINQ:

Datagridview1.Columns.Cast<DataGridViewColumn>().ToList().ForEach(f => f.SortMode = DataGridViewColumnSortMode.NotSortable);

Use ModRewrite:

RewriteRule ^403.html$ - [F]

Just make sure you create a blank document called "403.html" in your www root or you'll get a 404 error instead of 403.

I do this is a bunch of my apps and I use a statement like this:

  var inputDirectory = new DirectoryInfo("\\Directory_Path_here");
  var myFile = inputDirectory.GetFiles().OrderByDescending(f => f.LastWriteTime).First();

From here you will have the filename for the most recently saved/added/updated file in the Directory of the "inputDirectory" variable. Now you can access it and do what you want with it.

Hope that helps.

AFNetworking for Android:

Fast Android Networking is here

Fast Android Networking Library supports all types of HTTP/HTTPS request like GET, POST, DELETE, HEAD, PUT, PATCH

Fast Android Networking Library supports downloading any type of file

Fast Android Networking Library supports uploading any type of file (supports multipart upload)

Fast Android Networking Library supports cancelling a request

Fast Android Networking Library supports setting priority to any request (LOW, MEDIUM, HIGH, IMMEDIATE)

Fast Android Networking Library supports RxJava

As it uses OkHttp as a networking layer, it supports:

Fast Android Networking Library supports HTTP/2 support allows all requests to the same host to share a socket

Fast Android Networking Library uses connection pooling which reduces request latency (if HTTP/2 isn’t available)

Transparent GZIP shrinks download sizes

Fast Android Networking Library supports response caching which avoids the network completely for repeat requests

Thanks: The library is created by me

I also had this issue and it arose because I re-made the project and then forgot to re-link it by reference in a dependent project.

Thus it was linking by reference to the old project instead of the new one.

It is important to know that there is a bug in re-adding a previously linked project by reference. You've got to manually delete the reference in the vcxproj and only then can you re-add it. This is a known issue in Visual studio according to msdn.

if you are using sdkman

you can check it with sdk home java <installed_java_version>

$  sdk home java 8.0.252.j9-adpt
/Users/admin/.sdkman/candidates/java/8.0.252.j9-adpt

you can get your installed java version with

$ sdk list java

for my experience, Ellipsis works only if below two attributes are set.

android:ellipsize="end"
android:singleLine="true"

for the width of textview, wrap_content or match_parent should both be good.

You need to change public void klik(PaintEventArgs pea, EventArgs e) to public void klik(object sender, System.EventArgs e) because there is no Click event handler with parameters PaintEventArgs pea, EventArgs e.

You can use Url Parameters from the official documentation.

Example: this.httpClient.get(this.API, { params: new HttpParams().set('noCover', noCover) })

Someone posted this link to the MDN in a comment, and I think it was very helpful. It describes things like ErrorTypes very thoroughly.

EvalError --- Creates an instance representing an error that occurs regarding the global function eval().

InternalError --- Creates an instance representing an error that occurs when an internal error in the JavaScript engine is thrown. E.g. "too much recursion".

RangeError --- Creates an instance representing an error that occurs when a numeric variable or parameter is outside of its valid range.

ReferenceError --- Creates an instance representing an error that occurs when de-referencing an invalid reference.

SyntaxError --- Creates an instance representing a syntax error that occurs while parsing code in eval().

TypeError --- Creates an instance representing an error that occurs when a variable or parameter is not of a valid type.

URIError --- Creates an instance representing an error that occurs when encodeURI() or decodeURI() are passed invalid parameters.

You can do this in many ways before clicking on add items:

WebDriverWait wait = new WebDriverWait(driver, 40);
wait.until(ExpectedConditions.elementToBeClickable(By.id("urelementid")));// instead of id u can use cssSelector or xpath of ur element.


or

wait.until(ExpectedConditions.visibilityOfElementLocated("urelement"));

You can also wait like this. If you want to wait until invisible of previous page element:

wait.until(ExpectedConditions.invisibilityOfElementLocated("urelement"));

Here is the link where you can find all the Selenium WebDriver APIs that can be used for wait and its documentation.

https://selenium.googlecode.com/git/docs/api/java/org/openqa/selenium/support/ui/ExpectedConditions.html

You can use property dangerouslySetInnerHTML, like this

const Component = React.createClass({_x000D_
  iframe: function () {_x000D_
    return {_x000D_
      __html: this.props.iframe_x000D_
    }_x000D_
  },_x000D_
_x000D_
  render: function() {_x000D_
    return (_x000D_
      <div>_x000D_
        <div dangerouslySetInnerHTML={ this.iframe() } />_x000D_
      </div>_x000D_
    );_x000D_
  }_x000D_
});_x000D_
_x000D_
const iframe = '<iframe src="https://www.example.com/show?data..." width="540" height="450"></iframe>'; _x000D_
_x000D_
ReactDOM.render(_x000D_
  <Component iframe={iframe} />,_x000D_
  document.getElementById('container')_x000D_
);

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

also, you can copy all attributes from the string(based on the question, you get iframe as a string from a server) which contains <iframe> tag and pass it to new <iframe> tag, like that

/**_x000D_
 * getAttrs_x000D_
 * returns all attributes from TAG string_x000D_
 * @return Object_x000D_
 */_x000D_
const getAttrs = (iframeTag) => {_x000D_
  var doc = document.createElement('div');_x000D_
  doc.innerHTML = iframeTag;_x000D_
_x000D_
  const iframe = doc.getElementsByTagName('iframe')[0];_x000D_
  return [].slice_x000D_
    .call(iframe.attributes)_x000D_
    .reduce((attrs, element) => {_x000D_
      attrs[element.name] = element.value;_x000D_
      return attrs;_x000D_
    }, {});_x000D_
}_x000D_
_x000D_
const Component = React.createClass({_x000D_
  render: function() {_x000D_
    return (_x000D_
      <div>_x000D_
        <iframe {...getAttrs(this.props.iframe) } />_x000D_
      </div>_x000D_
    );_x000D_
  }_x000D_
});_x000D_
_x000D_
const iframe = '<iframe src="https://www.example.com/show?data..." width="540" height="450"></iframe>'; _x000D_
_x000D_
ReactDOM.render(_x000D_
  <Component iframe={iframe} />,_x000D_
  document.getElementById('container')_x000D_
);

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

I had the same problem. Now its working fine after doing below changes.

https://www.google.com/settings/security/lesssecureapps

You should change the "Access for less secure apps" to Enabled (it was enabled, I changed to disabled and than back to enabled). After a while I could send email.

Best way for Laravel 5.8

100% worked

Add this function inside your Auth\LoginController.php

use Illuminate\Http\Request;

And also add this

public function logout(Request $request)
{
    $this->guard()->logout();

    $request->session()->invalidate();

    return $this->loggedOut($request) ?: redirect('/login');
}

I have today similar problem. But weirder.

Revelation

Eventually I used strace on curl and found that it was connection to nscd deamon.

connect(4, {sa_family=AF_LOCAL, sun_path="/var/run/nscd/socket"}, 110) = 0

Solution

I've restarted the nscd service (Name Service Cache Daemon) and it helped to solve this issue!

systemctl restart nscd.service

Extending bp's answer, I wanted to show you what he meant by immutable types.

First, this is okay:

>>> class TestB():
...     def __init__(self, attr=1):
...         self.attr = attr
...     
>>> a = TestB()
>>> b = TestB()
>>> a.attr = 2
>>> a.attr
2
>>> b.attr
1

However, this only works for immutable (unchangable) types. If the default value was mutable (meaning it can be replaced), this would happen instead:

>>> class Test():
...     def __init__(self, attr=[]):
...         self.attr = attr
...     
>>> a = Test()
>>> b = Test()
>>> a.attr.append(1)
>>> a.attr
[1]
>>> b.attr
[1]
>>> 

Note that both a and b have a shared attribute. This is often unwanted.

This is the Pythonic way of defining default values for instance variables, when the type is mutable:

>>> class TestC():
...     def __init__(self, attr=None):
...         if attr is None:
...             attr = []
...         self.attr = attr
...     
>>> a = TestC()
>>> b = TestC()
>>> a.attr.append(1)
>>> a.attr
[1]
>>> b.attr
[]

The reason my first snippet of code works is because, with immutable types, Python creates a new instance of it whenever you want one. If you needed to add 1 to 1, Python makes a new 2 for you, because the old 1 cannot be changed. The reason is mostly for hashing, I believe.

here's non-paste methods

awk

awk 'BEGIN {OFS=" "}{
  getline line < "file2"
  print $0,line
} ' file1

Bash

exec 6<"file2"
while read -r line
do
    read -r f2line <&6
    echo "${line}${f2line}"
done <"file1"
exec 6<&-

Case 1: Original Question (No Libraries)

Plenty of other answers that work. :)

Case 2: Original Question (Lodash.js or Underscore.js)

var groups = _.groupBy(itemArray, 1);
var result = _.map(sortArray, function (i) { return groups[i].shift(); });

Case 3: Sort Array1 as if it were Array2

I'm guessing that most people came here looking for an equivalent to PHP's array_multisort (I did) so I thought I'd post that answer as well. There are a couple options:

1. There's an existing JS implementation of array_multisort(). Thanks to @Adnan for pointing it out in the comments. It is pretty large, though.

2. Write your own. (JSFiddle demo)

function refSort (targetData, refData) {
  // Create an array of indices [0, 1, 2, ...N].
  var indices = Object.keys(refData);

  // Sort array of indices according to the reference data.
  indices.sort(function(indexA, indexB) {
    if (refData[indexA] < refData[indexB]) {
      return -1;
    } else if (refData[indexA] > refData[indexB]) {
      return 1;
    }
    return 0;
  });

  // Map array of indices to corresponding values of the target array.
  return indices.map(function(index) {
    return targetData[index];
  });
}

3. Lodash.js or Underscore.js (both popular, smaller libraries that focus on performance) offer helper functions that allow you to do this:

    var result = _.chain(sortArray)
      .pairs()
      .sortBy(1)
      .map(function (i) { return itemArray[i[0]]; })
      .value();

...Which will (1) group the sortArray into [index, value] pairs, (2) sort them by the value (you can also provide a callback here), (3) replace each of the pairs with the item from the itemArray at the index the pair originated from.

Close

When you have finished using a socket, you can simply close its file descriptor with close; If there is still data waiting to be transmitted over the connection, normally close tries to complete this transmission. You can control this behavior using the SO_LINGER socket option to specify a timeout period; see Socket Options.

ShutDown

You can also shut down only reception or transmission on a connection by calling shutdown.

The shutdown function shuts down the connection of socket. Its argument how specifies what action to perform: 0 Stop receiving data for this socket. If further data arrives, reject it. 1 Stop trying to transmit data from this socket. Discard any data waiting to be sent. Stop looking for acknowledgement of data already sent; don’t retransmit it if it is lost. 2 Stop both reception and transmission.

The return value is 0 on success and -1 on failure.

you can also use the Readonly attribute: the input is not gonna be grayed but it won't be editable

<input type="text" name="lat" value="22.2222" readonly="readonly" />

A simple answer is to replace this line:

<script type="text/javascript" src="your_directory/bootstrap.min.js"></script>

for this other:

<script type="text/javascript" src="your_directory/bootstrap.bundle.min.js"></script>

java.time

The java.time framework in Java 8 and later supplants the old java.util.Date/.Calendar classes. The old classes have proven to be troublesome, confusing, and flawed. Avoid them.

The java.time framework is inspired by the highly-successful Joda-Time library, defined by JSR 310, extended by the ThreeTen-Extra project, and explained in the Tutorial.

Instant

The Instant class represents a moment on the timeline in UTC.

The java.time framework has a resolution of nanoseconds, or 9 digits of a fractional second. Milliseconds is only 3 digits of a fractional second. Because millisecond resolution is common, java.time includes a handy factory method.

long millisecondsSinceEpoch = 1446959825213L;
Instant instant = Instant.ofEpochMilli ( millisecondsSinceEpoch );

millisecondsSinceEpoch: 1446959825213 is instant: 2015-11-08T05:17:05.213Z

ZonedDateTime

To consider current week and current month, we need to apply a particular time zone.

ZoneId zoneId = ZoneId.of ( "America/Montreal" );
ZonedDateTime zdt = ZonedDateTime.ofInstant ( instant , zoneId );

In zoneId: America/Montreal that is: 2015-11-08T00:17:05.213-05:00[America/Montreal]

Half-Open

In date-time work, we commonly use the Half-Open approach to defining a span of time. The beginning is inclusive while the ending in exclusive. Rather than try to determine the last split-second of the end of the week (or month), we get the first moment of the following week (or month). So a week runs from the first moment of Monday and goes up to but not including the first moment of the following Monday.

Let's the first day of the week, and last. The java.time framework includes a tool for that, the with method and the ChronoField enum.

By default, java.time uses the ISO 8601 standard. So Monday is the first day of the week (1) and Sunday is last (7).

ZonedDateTime firstOfWeek = zdt.with ( ChronoField.DAY_OF_WEEK , 1 ); // ISO 8601, Monday is first day of week.
ZonedDateTime firstOfNextWeek = firstOfWeek.plusWeeks ( 1 );

That week runs from: 2015-11-02T00:17:05.213-05:00[America/Montreal] to 2015-11-09T00:17:05.213-05:00[America/Montreal]

Oops! Look at the time-of-day on those values. We want the first moment of the day. The first moment of the day is not always 00:00:00.000 because of Daylight Saving Time (DST) or other anomalies. So we should let java.time make the adjustment on our behalf. To do that, we must go through the LocalDate class.

ZonedDateTime firstOfWeek = zdt.with ( ChronoField.DAY_OF_WEEK , 1 ); // ISO 8601, Monday is first day of week.
firstOfWeek = firstOfWeek.toLocalDate ().atStartOfDay ( zoneId );
ZonedDateTime firstOfNextWeek = firstOfWeek.plusWeeks ( 1 );

That week runs from: 2015-11-02T00:00-05:00[America/Montreal] to 2015-11-09T00:00-05:00[America/Montreal]

And same for the month.

ZonedDateTime firstOfMonth = zdt.with ( ChronoField.DAY_OF_MONTH , 1 );
firstOfMonth = firstOfMonth.toLocalDate ().atStartOfDay ( zoneId );
ZonedDateTime firstOfNextMonth = firstOfMonth.plusMonths ( 1 );

That month runs from: 2015-11-01T00:00-04:00[America/Montreal] to 2015-12-01T00:00-05:00[America/Montreal]

YearMonth

Another way to see if a pair of moments are in the same month is to check for the same YearMonth value.

For example, assuming thisZdt and thatZdt are both ZonedDateTime objects:

boolean inSameMonth = YearMonth.from( thisZdt ).equals( YearMonth.from( thatZdt ) ) ;

Milliseconds

I strongly recommend against doing your date-time work in milliseconds-from-epoch. That is indeed the way date-time classes tend to work internally, but we have the classes for a reason. Handling a count-from-epoch is clumsy as the values are not intelligible by humans so debugging and logging is difficult and error-prone. And, as we've already seen, different resolutions may be in play; old Java classes and Joda-Time library use milliseconds, while databases like Postgres use microseconds, and now java.time uses nanoseconds.

Would you handle text as bits, or do you let classes such as String, StringBuffer, and StringBuilder handle such details?

But if you insist, from a ZonedDateTime get an Instant, and from that get a milliseconds-count-from-epoch. But keep in mind this call can mean loss of data. Any microseconds or nanoseconds that you might have in your ZonedDateTime/Instant will be truncated (lost).

long millis = firstOfWeek.toInstant().toEpochMilli();  // Possible data loss.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

Here's a way to avoid this vexing problem when you start a new project:

• Create the main directory for your new project.
• Run git init.
• Now create a .gitignore file (even if it's empty).
• Commit your .gitignore file.

Git makes it really hard to do git reset if you don't have any commits. If you create a tiny initial commit just for the sake of having one, after that you can git add -A and git reset as many times as you want in order to get everything right.

Another advantage of this method is that if you run into line-ending troubles later and need to refresh all your files, it's easy:

• Check out that initial commit. This will remove all your files.
• Then check out your most recent commit again. This will retrieve fresh copies of your files, using your current line-ending settings.

You can use this function to query for any element on the page, regardless of if it is nested inside of an iframe (or many iframes):

function querySelectorAllInIframes(selector) {
  let elements = [];

  const recurse = (contentWindow = window) => {

    const iframes = contentWindow.document.body.querySelectorAll('iframe');
    iframes.forEach(iframe => recurse(iframe.contentWindow));
    
    elements = elements.concat(contentWindow.document.body.querySelectorAll(selector));
  }

  recurse();

  return elements;
};

querySelectorAllInIframes('#elementToBeFound');

Note: Keep in mind that each of the iframes on the page will need to be of the same-origin, or this function will throw an error.

In case you are looking for parsing (positive, unsigned) integers instead of floats, you can use the isdigit() function for string objects.

>>> a = "03523"
>>> a.isdigit()
True
>>> b = "963spam"
>>> b.isdigit()
False

String Methods - isdigit(): Python2, Python3

There's also something on Unicode strings, which I'm not too familiar with Unicode - Is decimal/decimal

Continuing this answer, There is another difference that if you want your method to return different values for example when it is first time called, second time called etc then you can pass values so for example...

PowerMockito.doReturn(false, false, true).when(SomeClass.class, "SomeMethod", Matchers.any(SomeClass.class));

So it will return false when the method is called in same test case and then it will return false again and lastly true.

If your object could contain any key/value pairs, you could declare an interface called keyable like :

interface keyable {
    [key: string]: any  
}

then use it as follows :

let countryProviders: keyable[];

or

let countryProviders: Array<keyable>;

decimal d = 3.00 is still 3. I guess you want to show it some where on screen or print it on log file as 3.00. You can do following

string str = d.ToString("F2");

or if you are using database to store the decimal then you can set pricision value in database.

I basically do like this, create new element and attach that to <head>

var x = document.createElement('script');
x.src = 'http://example.com/test.js';
document.getElementsByTagName("head")[0].appendChild(x);

You may also use onload event to each script you attach, but please test it out, I am not so sure it works cross-browser or not.

x.onload=callback_function;

Based on your comments in this answer, I do what you're trying to do like this:

module.exports = function (app, db) {
    var module = {};

    module.auth = function (req, res) {
        // This will be available 'outside'.
        // Authy stuff that can be used outside...
    };

    // Other stuff...
    module.pickle = function(cucumber, herbs, vinegar) {
        // This will be available 'outside'.
        // Pickling stuff...
    };

    function jarThemPickles(pickle, jar) {
        // This will be NOT available 'outside'.
        // Pickling stuff...

        return pickleJar;
    };

    return module;
};

I structure pretty much all my modules like that. Seems to work well for me.

Below steps worked for me:

1) Delete the node_modules/ folder and package-lock.json file.

2) npm install

3) ng serve

1. Download ARM Translation v1.1 and flash it by dragging and dropping over the emulator. Then reboot the emulator.
2. Go to Open GApps, select x86 architecture, Android version of your emulator and variant (nano is enough, other applications can be installed from Play Store) and download zip archive. Drag and drop this archive to the emulator and flash it. Reboot the emulator.

Try this instead in the end:

exec (@query)

If you do not have the brackets, SQL Server assumes the value of the variable to be a stored procedure name.

OR

EXECUTE sp_executesql @query

And it should not be because of FULL JOIN.
But I hope you have already created the temp tables: #TrafficFinal, #TrafficFinal2, #TrafficFinal3 before this.

Please note that there are performance considerations between using EXEC and sp_executesql. Because sp_executesql uses forced statement caching like an sp.
More details here.

On another note, is there a reason why you are using dynamic sql for this case, when you can use the query as is, considering you are not doing any query manipulations and executing it the way it is?

You may have several php.ini files, one for CLI and one for apache. Run php --ini to see where the CLI ini location is.

It's only blank for you because you have not set the sql_mode. If you set it, then that query will show you the details:

If it's in the same class with the equal number of parameters with the same types and order, then it is not possible for example:

int methoda(String a,int b) {
        return b;
}
String methoda(String b,int c) {
        return b;    
}

if the number of parameters and their types is same but order is different then it is possible since it results in method overloading. It means if the method signature is same which includes method name with number of parameters and their types and the order they are defined.

The syntax is:

=GOOGLEFINANCE(ticker, [attribute], [start_date], [num_days|end_date], [interval])

Sample usage:

=GOOGLEFINANCE("GOOG", "price", DATE(2014,1,1), DATE(2014,12,31), "DAILY")
=GOOGLEFINANCE("GOOG","price",TODAY()-30,TODAY())
=GOOGLEFINANCE(A2,A3)
=117.80*Index(GOOGLEFINANCE("CURRENCY:EURGBP", "close", DATE(2014,1,1)), 2, 2)

For instance if you'd like to convert the rate on specific date, here is some more advanced example:

=IF($C2 = "GBP", "", Index(GoogleFinance(CONCATENATE("CURRENCY:", C2, "GBP"), "close", DATE(year($A2), month($A2), day($A2)), DATE(year($A2), month($A2), day($A2)+1), "DAILY"), 2))

where $A2 is your date (e.g. 01/01/2015) and C2 is your currency (e.g. EUR).

See more samples at Docs editors Help at Google.

Use:

• :ls - to list buffers
• :bd#n - to close buffer where #n is the buffer number (use ls to get it)

Examples:

• to delete buffer 2:

  :bd2
  

<merge/> is useful because it can get rid of unneeded ViewGroups, i.e. layouts that are simply used to wrap other views and serve no purpose themselves.

For example, if you were to <include/> a layout from another file without using merge, the two files might look something like this:

layout1.xml:

<FrameLayout>
   <include layout="@layout/layout2"/>
</FrameLayout>

layout2.xml:

<FrameLayout>
   <TextView />
   <TextView />
</FrameLayout>

which is functionally equivalent to this single layout:

<FrameLayout>
   <FrameLayout>
      <TextView />
      <TextView />
   </FrameLayout>
</FrameLayout>

That FrameLayout in layout2.xml may not be useful. <merge/> helps get rid of it. Here's what it looks like using merge (layout1.xml doesn't change):

layout2.xml:

<merge>
   <TextView />
   <TextView />
</merge>

This is functionally equivalent to this layout:

<FrameLayout>
   <TextView />
   <TextView />
</FrameLayout>

but since you are using <include/> you can reuse the layout elsewhere. It doesn't have to be used to replace only FrameLayouts - you can use it to replace any layout that isn't adding something useful to the way your view looks/behaves.

As others have said, it's a direct child, but it's worth noting that this is different to just leaving a space... a space is for any descendant.

<div>
  <span>Some text</span>
</div>

div>span would match this, but it would not match this:

<div>
  <p><span>Some text</span></p>
</div>

To match that, you could do div>p>span or div span.

If you are using TextEditingController then set the text to it, like below

TextEditingController _controller = new TextEditingController();


_controller.text = 'your initial text';

final your_text_name = TextFormField(
      autofocus: false,
      controller: _controller,
      decoration: InputDecoration(
        hintText: 'Hint Value',
      ),
    );

and if you are not using any TextEditingController then you can directly use initialValue like below

final last_name = TextFormField(
      autofocus: false,
      initialValue: 'your initial text',
      decoration: InputDecoration(
        hintText: 'Last Name',
      ),
    );

Update

One more reason why read the documentation for Symfony will never go out of trend. There is a simple solution for my specific case and is to set the field type option empty_data to a default value.

Again, this solution is only for the scenario where an empty input in a form sets the DB field to null.

Background

None of the previous answers helped me with my specific scenario but I found a solution.

I had a form field that needed to behave as follow:

1. Not required, could be left blank. (Used 'required' => false)
2. If left blank, it should default to a given value. For better user experience, I did not set the default value on the input field but rather used the html attribute 'placeholder' since it is less obtrusive.

I then tried all the recommendations given in here. Let me list them:

• Set a default value when for the entity property:

<?php
/**
 * @Entity
 */
class myEntity {
    /**
     * @var string
     *
     * @Column(name="myColumn", type="string", length="50")
     */
    private $myColumn = 'myDefaultValue';
    ...
}

• Use the options annotation:

@ORM\Column(name="foo", options={"default":"foo bar"})

• Set the default value on the constructor:

/**
 * @Entity
 */
class myEntity {
    ...
    public function __construct()
    {
        $this->myColumn = 'myDefaultValue';
    }
    ...
}

IMPORTANT

Symfony form fields override default values set on the Entity class. Meaning, your schema for your DB can have a default value defined but if you leave a non-required field empty when submitting your form, the form->handleRequest() inside your form->isValid() method will override those default values on your Entity class and set them to the input field values. If the input field values are blank, then it will set the Entity property to null.

http://symfony.com/doc/current/book/forms.html#handling-form-submissions

My Workaround

Set the default value on your controller after form->handleRequest() inside your form->isValid() method:

...
if ($myEntity->getMyColumn() === null) {
    $myEntity->setMyColumn('myDefaultValue');
}
...

Not a beautiful solution but it works. I could probably make a validation group but there may be people that see this issue as a data transformation rather than data validation, I leave it to you to decide.

Override Setter (Does Not Work)

I also tried to override the Entity setter this way:

...
/**
 * Set myColumn
 *
 * @param string $myColumn
 *
 * @return myEntity
 */
public function setMyColumn($myColumn)
{
    $this->myColumn = ($myColumn === null || $myColumn === '') ? 'myDefaultValue' : $myColumn;

    return $this;
}
...

This, even though it looks cleaner, it doesn't work. The reason being that the evil form->handleRequest() method does not use the Model's setter methods to update the data (dig into form->setData() for more details).

Sessions are stored on the server and are set from server side code, not client side code such as JavaScript.

What you want is a cookie, someone's given a brilliant explanation in this Stack Overflow question here: How do I set/unset cookie with jQuery?

You could potentially use sessions and set/retrieve them with jQuery and AJAX, but it's complete overkill if Cookies will do the trick.

maybe requests-futures is another choice.

from requests_futures.sessions import FuturesSession

session = FuturesSession()
# first request is started in background
future_one = session.get('http://httpbin.org/get')
# second requests is started immediately
future_two = session.get('http://httpbin.org/get?foo=bar')
# wait for the first request to complete, if it hasn't already
response_one = future_one.result()
print('response one status: {0}'.format(response_one.status_code))
print(response_one.content)
# wait for the second request to complete, if it hasn't already
response_two = future_two.result()
print('response two status: {0}'.format(response_two.status_code))
print(response_two.content)

It is also recommended in the office document. If you don't want involve gevent, it's a good one.

Important Update

Go to project level build.gradle, define global variables

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext.kotlinVersion = '1.2.61'

    ext.global_minSdkVersion = 16
    ext.global_targetSdkVersion = 28
    ext.global_buildToolsVersion = '28.0.1'
    ext.global_supportLibVersion = '27.1.1'
}

Go to app level build.gradle, and use global variables

app build.gradle

android {
    compileSdkVersion global_targetSdkVersion
    buildToolsVersion global_buildToolsVersion
    defaultConfig {
        minSdkVersion global_minSdkVersion
        targetSdkVersion global_targetSdkVersion
}
...

dependencies {
    implementation "com.android.support:appcompat-v7:$global_supportLibVersion"
    implementation "com.android.support:recyclerview-v7:$global_supportLibVersion"
    // and so on...
}

some library build.gradle

android {
    compileSdkVersion global_targetSdkVersion
    buildToolsVersion global_buildToolsVersion
    defaultConfig {
        minSdkVersion global_minSdkVersion
        targetSdkVersion global_targetSdkVersion
}
...

dependencies {
    implementation "com.android.support:appcompat-v7:$global_supportLibVersion"
    implementation "com.android.support:recyclerview-v7:$global_supportLibVersion"
    // and so on...
}

The solution is to make your versions same as in all modules. So that you don't have conflicts.

Important Tips

I felt when I have updated versions of everything- gradle, sdks, libraries etc. then I face less errors. Because developers are working hard to make it easy development on Android Studio.

Always have latest but stable versions Unstable versions are alpha, beta and rc, ignore them in developing.

I have updated all below in my projects, and I don't face these errors anymore.

• Update Android Studio (Track release)
• Project level build.gradle - classpath 'com.android.tools.build:gradle:3.2.0' (Track android.build.gradle release & this)
• Have updated buildToolVersion (Track buildToolVersion release)
• Have latest compileSdkVersion and targetSdkVersion Track platform release
• Have updated library versions, because after above updates, its necessary. (@See How to update)

Happy coding! :)

You can use the CSS property background-size and set it to cover or contain, depending your preference. Cover will cover the window entirely, while contain will make one side fit the window thus not covering the entire page (unless the aspect ratio of the screen is equal to the image).

Please note that this is a CSS3 property. In older browsers, this property is ignored. Alternatively, you can use javascript to change the CSS settings depending on the window size, but this isn't preferred.

body {
    background-image: url(image.jpg); /* image */
    background-position: center;      /* center the image */
    background-size: cover;           /* cover the entire window */
}

For JSF-based Maven web applications, just use ClassLoader and the Resources folder to read in any file you want:

1. Put any file you want to read in the Resources folder.

2. Put the Apache Commons IO dependency into your POM:

   <dependency>
       <groupId>org.apache.commons</groupId>
       <artifactId>commons-io</artifactId>
       <version>1.3.2</version>
   </dependency>
   

3. Use the code below to read it (e.g. below is reading in a .json file):

   String metadata = null;
   FileInputStream inputStream;
   try {
   
       ClassLoader loader = Thread.currentThread().getContextClassLoader();
       inputStream = (FileInputStream) loader
               .getResourceAsStream("/metadata.json");
       metadata = IOUtils.toString(inputStream);
       inputStream.close();
   }
   catch (FileNotFoundException e) {
       // TODO Auto-generated catch block
       e.printStackTrace();
   }
   catch (IOException e) {
       // TODO Auto-generated catch block
       e.printStackTrace();
   }
   return metadata;
   

You can do the same for text files, .properties files, XSD schemas, etc.

A simple &nbsp; between input fields would do the job easily...

jQuery has very limited array functions since JavaScript has most of them itself. But here are the ones they have: Utilities - jQuery API.

Image alpha sets just opacity to ImageView which makes Image blurry, try adding tint attribute in ImageView

 android:tint="#66000000"

It can also be done programatically :

imageView.setColorFilter(R.color.transparent);

where you need to define transparent color in your colors.xml

<color name="transparent">#66000000</color>

This is plain Javascript and has nothing to do with the jQuery library.

You simply escape the apostrophe with a backslash:

theAnchorText = 'I\'m home';

Another alternative is to use quotation marks around the string, then you don't have to escape apostrophes:

theAnchorText = "I'm home";

SELECT d1.Short_Code 
FROM domain1 d1
LEFT JOIN domain2 d2
ON d1.Short_Code = d2.Short_Code
WHERE d2.Short_Code IS NULL

Easiest method: Alt+Enter on

private static final long serialVersionUID = ;

IntelliJ will underline the space after the =. put your cursor on it and hit alt+Enter (Option+Enter on Mac). You'll get a popover that says "Randomly Change serialVersionUID Initializer". Just hit enter, and it'll populate that space with a random long.

I got the same error from having two references to different versions of jQuery.
