Even without looking at assembly, the most obvious reason is that /= 2 is probably optimized as >>=1 and many processors have a very quick shift operation. But even if a processor doesn't have a shift operation, the integer division is faster than floating point division.

Edit: your milage may vary on the "integer division is faster than floating point division" statement above. The comments below reveal that the modern processors have prioritized optimizing fp division over integer division. So if someone were looking for the most likely reason for the speedup which this thread's question asks about, then compiler optimizing /=2 as >>=1 would be the best 1st place to look.

On an unrelated note, if n is odd, the expression n*3+1 will always be even. So there is no need to check. You can change that branch to

{
   n = (n*3+1) >> 1;
   count += 2;
}

So the whole statement would then be

if (n & 1)
{
    n = (n*3 + 1) >> 1;
    count += 2;
}
else
{
    n >>= 1;
    ++count;
}

You can just use a Hook

add_filter( 'nav_menu_submenu_css_class', 'some_function', 10, 3 );
function some_function( $classes, $args, $depth ){
    foreach ( $classes as $key => $class ) {
    if ( $class == 'sub-menu' ) {
        $classes[ $key ] = 'my-sub-menu';
    }
}

return $classes;
}

where

$classes(array) - The CSS classes that are applied to the menu <ul> element.
$args(stdClass) - An object of wp_nav_menu() arguments.
$depth(int) - Depth of menu item. Used for padding.

This worked for me,

echo > file.extension

Here's another way I found today, got ideas from other answers but it worked

sometext > filename.extension

Eg.

xyz > emptyfile.txt  //this would create an empty zero byte text file
abc > filename.mp4   //this would create an zero byte MP4 video media file

This would show an error message in the command prompt that ,

xyz is not as an internal or external command, operable program or batch file.

But the weird thing I found was the file is being created in the directory even if the command is not a standard windows command.

If you're goal is to write this information to the database, then why do you need to have a primary value and 'related' values in the value attribute? Why not just send the primary value to the database and let the relational nature of the database take care of the rest.

If you need to have multiple values in your OPTIONs, try a delimiter that isn't very common:

<OPTION VALUE="1|2010">One</OPTION>

...

or add an object literal (JSON format):

<OPTION VALUE="{'primary':'1','secondary':'2010'}">One</OPTION>

...

It really depends on what you're trying to do.

In stall PuTTY in our system and set the environment variable PATH Pointing to putty path. open the command prompt and move to putty folder. Using PSCP command

Please check this

You can try to use the following code instead:

 $pro= model_name::where('col_name', '=', 'value')->get();

Using following single line code you can get status bar height in any orientation and also if it is visible or not

#define STATUS_BAR_HIGHT (
    [UIApplicationsharedApplication].statusBarHidden ? 0 : (
        [UIApplicationsharedApplication].statusBarFrame.size.height > 100 ?
            [UIApplicationsharedApplication].statusBarFrame.size.width :
            [UIApplicationsharedApplication].statusBarFrame.size.height
    )
)

It just a simple but very useful macro just try this you don't need to write any extra code

You can use str.isalpha().

For example:

s = 'a123b'

for char in s:
    print(char, char.isalpha())

Output:

a True
1 False
2 False
3 False
b True

choices = {'key1':'val1', 'key2':'val2'}

Here's the template:

<ul>
{% for key, value in choices.items %} 
  <li>{{key}} - {{value}}</li>
{% endfor %}
</ul>

Basically, .items is a Django keyword that splits a dictionary into a list of (key, value) pairs, much like the Python method .items(). This enables iteration over a dictionary in a Django template.

You have to export it from your NgModule:

@NgModule({
  declarations: [TaskCardComponent],
  exports: [TaskCardComponent],
  imports: [MdCardModule],
  providers: []
})
export class TaskModule{}

Trying to compress a PDF I made with 400ppi tiffs, mostly 8-bit, a few 24-bit, with PackBits compression, using tiff2pdf compressed with Zip/Deflate. One problem I had with every one of these methods: none of the above methods preserved the bookmarks TOC that I painstakingly manually created in Acrobat Pro X. Not even the recommended ebook setting for gs. Sure, I could just open a copy of the original with the TOC intact and do a Replace pages but unfortunately, none of these methods did a satisfactory job to begin with. Either they reduced the size so much that the quality was unacceptably pixellated, or they didn't reduce the size at all and in one case actually increased it despite quality loss.

You might try removing the BufferedWriter and just using the FileWriter directly. On a modern system there's a good chance you're just writing to the drive's cache memory anyway.

It takes me in the range of 4-5 seconds to write 175MB (4 million strings) -- this is on a dual-core 2.4GHz Dell running Windows XP with an 80GB, 7200-RPM Hitachi disk.

Can you isolate how much of the time is record retrieval and how much is file writing?

You can just put a pause command in the last line of your batch file:

@echo off
echo Hey, I'm just doing some work for you.
pause

Will give you something like this as output:

Hey, I'm just doing some work for you.

Press any key to continue ...

Note: Using the @echo prevents to output the command before the output is printed.

The best way is to run this batch file. open notepad and type:-

@echo off
echo Set oWS = WScript.CreateObject("WScript.Shell") > CreateShortcut.vbs
echo sLinkFile = "GIVETHEPATHOFLINK.lnk" >> CreateShortcut.vbs
echo Set oLink = oWS.CreateShortcut(sLinkFile) >> CreateShortcut.vbs
echo oLink.TargetPath = "GIVETHEPATHOFTARGETFILEYOUWANTTHESHORTCUT" >> CreateShortcut.vbs
echo oLink.Save >> CreateShortcut.vbs
cscript CreateShortcut.vbs
del CreateShortcut.vbs

(RU) ?? ??????? ???? ?????? ????? ???????? ??? - $_POST['data__value']; ???????? ??? ????????? ???????? first_name ?? ???????, ????? ????????:

(EN) On the server, you can get your data as - $_POST ['data__value']; For example, to get the first_name value on the server, write:

$test = json_decode( $_POST['data__value'] );
echo $test->first_name;

In Visual Studio 2015 (this still holds in 2019 for the same value), check the setting:

Tools > Options > Environment > Documents > Check for consistent line endings on load

VS2015 will now prompt you to convert line endings when you open a file where they are inconsistent, so all you need to do is open the files, select the desired option from the prompt and save them again.

I am promoting my comment to an answer:

The easy way is:

You could draw in the original 'frame' itself instead of using gray image.

The hard way (method you were trying to implement):

backtorgb = cv2.cvtColor(gray,cv2.COLOR_GRAY2RGB) is the correct syntax.

To send a message to a user you first need a User instance representing the user you want to send the message to.

Obtaining a User instance

• You can obtain a User instance from a message the user sent by doing message.autor
• You can obtain a User instance from a user id with client.fetchUser

Once you got a user instance you can send the message with .send

Examples

client.on('message', (msg) => {
 if (!msg.author.bot) msg.author.send('ok ' + msg.author.id);
});

You can do one of two things:

• match against ^\s*$; a match means the string is "empty"
  • ^, $ are the beginning and end of string anchors respectively
  • \s is a whitespace character
  • * is zero-or-more repetition of
• find a \S; an occurrence means the string is NOT "empty"
  • \S is the negated version of \s (note the case difference)
  • \S therefore matches any non-whitespace character

References

• regular-expressions.info, Anchors, Repetition
• MSDN - Character classes - Whitespace character \s
  • Note that unless you're using RegexOptions.ECMAScript, \s matches things like ellipsis …

graphics.h appears to something once bundled with Borland and/or Turbo C++, in the 90's.

http://www.daniweb.com/software-development/cpp/threads/17709/88149#post88149

It's unlikely that you will find any support for that file with modern compiler. For other graphics libraries check the list of "related" questions (questions related to this one). E.g., "A Simple, 2d cross-platform graphics library for c or c++?".

How are you setting up the SqlParameter? You should set the SqlDbType property to SqlDbType.DateTime and then pass the DateTime directly to the parameter (do NOT convert to a string, you are asking for a bunch of problems then).

You should be able to get the value into the DB. If not, here is a very simple example of how to do it:

static void Main(string[] args)
{
    // Create the connection.
    using (SqlConnection connection = new SqlConnection(@"Data Source=..."))
    {
        // Open the connection.
        connection.Open();

        // Create the command.
        using (SqlCommand command = new SqlCommand("xsp_Test", connection))
        {
            // Set the command type.
            command.CommandType = System.Data.CommandType.StoredProcedure;

            // Add the parameter.
            SqlParameter parameter = command.Parameters.Add("@dt",
                System.Data.SqlDbType.DateTime);

            // Set the value.
            parameter.Value = DateTime.Now;

            // Make the call.
            command.ExecuteNonQuery();
        }
    }
}

I think part of the issue here is that you are worried that the fact that the time is in UTC is not being conveyed to SQL Server. To that end, you shouldn't, because SQL Server doesn't know that a particular time is in a particular locale/time zone.

If you want to store the UTC value, then convert it to UTC before passing it to SQL Server (unless your server has the same time zone as the client code generating the DateTime, and even then, that's a risk, IMO). SQL Server will store this value and when you get it back, if you want to display it in local time, you have to do it yourself (which the DateTime struct will easily do).

All that being said, if you perform the conversion and then pass the converted UTC date (the date that is obtained by calling the ToUniversalTime method, not by converting to a string) to the stored procedure.

And when you get the value back, call the ToLocalTime method to get the time in the local time zone.

There might two issues

1) $blogs may be a stdObject

or

2) The properties of the array might be the stdObject

Try using var_dump($blogs) and see the actual problem if the properties of array have stdObject try like this

$blog->id;
$blog->content;
$blog->title;

This might not be relevant to the actual question, but in my instance, I tried to implement Kotlin and left out apply plugin: 'kotlin-android'. The error happened because it could not recognize the MainActivity in as a .kt file.

Hope it helps someone.

Delete Without Rebooting

The OP's question indeed has been answered extensively, including how to avoid rebooting through powershell, vbscript, or you name it.

However, if you need to stick to cmd commands only and don't have the luxury of being able to call powershell or vbscript, you could use the following approach:

rem remove from current cmd instance
  SET FOOBAR=
rem remove from the registry if it's a user variable
  REG delete HKCU\Environment /F /V FOOBAR
rem remove from the registry if it's a system variable
  REG delete "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /F /V FOOBAR
rem tell Explorer.exe to reload the environment from the registry
  SETX DUMMY ""
rem remove the dummy
  REG delete HKCU\Environment /F /V DUMMY

So the magic here is that by using "setx" to assign something to a variable you don't need (in my example DUMMY), you force Explorer.exe to reread the variables from the registry, without needing powershell. You then clean up that dummy, and even though that one will stay in Explorer's environment for a little while longer, it will probably not harm anyone.

Or if after deleting variables you need to set new ones, then you don't even need any dummy. Just using SETX to set the new variables will automatically clear the ones you just removed from any new cmd tasks that might get started.

Background information: I just used this approach successfully to replace a set of user variables by system variables of the same name on all of the computers at my job, by modifying an existing cmd script. There are too many computers to do it manually, nor was it practical to copy extra powershell or vbscripts to all of them. The reason I urgently needed to replace user with system variables was that user variables get synchronized in roaming profiles (didn't think about that), so multiple machines using the same windows login but needing different values, got mixed up.

try this

$.getJSON(url, function(data){
    $.each(data.response.venue.tips.groups.items, function (index, value) {
        console.log(this.text);
    });
});

In case of HTML5 this will do the trick

window.onpopstate = function() {
   alert("clicked back button");
}; history.pushState({}, '');

You are setting the label text before the button is clicked to "txt". Instead when the button is clicked call setText() on the label and pass it the text from the text field.

Example:

label1.setText(nameField.getText()); 

The default port for SQL Server Database Engine is 1433.

And as a best practice it should always be changed after the installation. 1433 is widely known which makes it vulnerable to attacks.

In python you can do this very eaisly

start=0
end=10
arr=list(range(start,end+1))
output: arr=[0,1,2,3,4,5,6,7,8,9,10]

or you can create a recursive function that returns an array upto a given number:

ar=[]
def diff(start,end):
    if start==end:
        d.append(end)
        return ar
    else:
        ar.append(end)
        return diff(start-1,end) 

output: ar=[10,9,8,7,6,5,4,3,2,1,0]

private String generateAttachName(String fileName, String searchOn, String char1) {
    return fileName.replaceAll(searchOn, char1);
}


String fileName= generateAttachName("Hello My Mom","\\s","");

"pop"ing the first element of an Array is called "shift" ("unshift" being the operation of adding one element in front of the array).

If you want to initialize the list with N elements of some fixed value:

public List<T> InitList<T>(int count, T initValue)
{
  return Enumerable.Repeat(initValue, count).ToList();
}

it worked for me..

countries.results= $.grep(countries.results, function (e) { 
      if(e.id!= currentID) {
       return true; 
      }
     });

This is my powershell newbie way of doing this

if ((Test-Path ".\Desktop\checkfile.txt") -ne "True") {
    Write-Host "Damn it"
} else {
    Write-Host "Yay"
}

Adding my answer, because it elaborates the idea that you can SELECT multiple columns from the table from which you subquery.

Here I needed the the most recently cast cote and it's associated information.

I first tried simply to SELECT the max(votedate) along with vote, itemid, userid etc., but while the query would return the max votedate, it would also return the a random row for the other information. Hard to see among a bunch of 1s and 0s.

This worked well:

$query = "  
    SELECT t1.itemid, t1.itemtext, t2.vote, t2.votedate, t2.userid 
    FROM
        (
        SELECT itemid, itemtext FROM oc_item ) t1
    LEFT JOIN 
        (
        SELECT vote, votedate, itemid,userid FROM oc_votes
        WHERE votedate IN 
        (select max(votedate) FROM oc_votes group by itemid)
        AND userid=:userid) t2
    ON (t1.itemid = t2.itemid)
    order by itemid ASC
";

The subquery in the WHERE clause WHERE votedate IN (select max(votedate) FROM oc_votes group by itemid) returns one record - the record with the max vote date.

i had same problem, i have deleted E:\Mongo Data Files\db\mongod.lock file, so it started working. the problem is due to improper shutdown of server. so lock file is not clean.

This worked for me as well:

Get-ADUser -Filter * -SearchBase "ou=OU,dc=Domain,dc=com" -Properties Enabled, CanonicalName, Displayname, Givenname, Surname, EmployeeNumber, EmailAddress, Department, StreetAddress, Title | select Enabled, CanonicalName, Displayname, GivenName, Surname, EmployeeNumber, EmailAddress, Department, Title | Export-CSV "C:\output.csv"

Just to spell out something explicitly:

The main thread is basically the UI thread.

So saying that you cannot do networking operations in the main thread means you cannot do networking operations in the UI thread, which means you cannot do networking operations in a *runOnUiThread(new Runnable() { ... }* block inside some other thread, either.

(I just had a long head-scratching moment trying to figure out why I was getting that error somewhere other than my main thread. This was why; this thread helped; and hopefully this comment will help someone else.)

If you run the GWT compiler with the -localWorkers flag, the compiler will compile multiple permutations in parallel. This lets you use all the cores of a multi-core machine, for example -localWorkers 2 will tell the compiler to do compile two permutations in parallel. You won't get order of magnitudes differences (not everything in the compiler is parallelizable) but it is still a noticable speedup if you are compiling multiple permutations.

If you're willing to use the trunk version of GWT, you'll be able to use hosted mode for any browser (out of process hosted mode), which alleviates most of the current issues with hosted mode. That seems to be where the GWT is going - always develop with hosted mode, since compiles aren't likely to get magnitudes faster.

In my case, my server was configured to work only in https mode, and error occured when I try to access http mode. So changing http://my-service to https://my-service helped.

Sometimes doing this (the top-voted answer) is not always enough:

$('body').on('click', 'a.myclass', function() {
    // do something
});

This can be an issue because of the order event handlers are fired. If you find yourself doing this, but it is causing issues because of the order in which it is handled.. You can always wrap that into a function, that when called "refreshes" the listener.

For example:

function RefreshSomeEventListener() {
    // Remove handler from existing elements
    $("#wrapper .specific-selector").off(); 

    // Re-add event handler for all matching elements
    $("#wrapper .specific-selector").on("click", function() {
        // Handle event.
    }
}

Because it is a function, whenever I set up my listener this way, I typically call it on document ready:

$(document).ready(function() {
    // Other ready commands / code

    // Call our function to setup initial listening
    RefreshSomeEventListener();
});

Then, whenever you add some dynamically added element, call that method again:

function SomeMethodThatAddsElement() {
    // Some code / AJAX / whatever.. Adding element dynamically

    // Refresh our listener, so the new element is taken into account
    RefreshSomeEventListener();
}

Hopefully this helps!

Regards,

The Log class:

API for sending log output.

Generally, use the Log.v() Log.d() Log.i() Log.w() and Log.e() methods.

The order in terms of verbosity, from least to most is ERROR, WARN, INFO, DEBUG, VERBOSE. Verbose should never be compiled into an application except during development. Debug logs are compiled in but stripped at runtime. Error, warning and info logs are always kept.

Outside of Android, System.out.println(String msg) is used.

Using a single Awk:

... | awk -F '[/:]' '{print $5}'

That is, using as field separator either / or :, the username is always in field 5.

To store it in a variable:

username=$(... | awk -F '[/:]' '{print $5}')

A more flexible implementation with sed that doesn't require username to be field 5:

... | sed -e s/:.*// -e s?.*/??

That is, delete everything from : and beyond, and then delete everything up until the last /. sed is probably faster too than awk, so this alternative is definitely better.

The only way to know is to read your implementation's documentation.

In the C standard, section 6.10.2, paragraphs 2 to 4 state:

• A preprocessing directive of the form

  #include <h-char-sequence> new-line
  

  searches a sequence of implementation-defined places for a header identified uniquely by the specified sequence between the < and > delimiters, and causes the replacement of that directive by the entire contents of the header. How the places are specified or the header identified is implementation-defined.

• A preprocessing directive of the form

  #include "q-char-sequence" new-line
  

  causes the replacement of that directive by the entire contents of the source file identified by the specified sequence between the " delimiters. The named source file is searched for in an implementation-defined manner. If this search is not supported, or if the search fails, the directive is reprocessed as if it read

  #include <h-char-sequence> new-line
  

  with the identical contained sequence (including > characters, if any) from the original directive.

• A preprocessing directive of the form

  #include pp-tokens new-line
  

  (that does not match one of the two previous forms) is permitted. The preprocessing tokens after include in the directive are processed just as in normal text. (Each identifier currently defined as a macro name is replaced by its replacement list of preprocessing tokens.) The directive resulting after all replacements shall match one of the two previous forms. The method by which a sequence of preprocessing tokens between a < and a > preprocessing token pair or a pair of " characters is combined into a single header name preprocessing token is implementation-defined.

Definitions:

• h-char: any member of the source character set except the new-line character and >

• q-char: any member of the source character set except the new-line character and "

What about Regex.Replace solution?

myStr = Regex.Replace(myStr, "\s", "")

Well, the best way is to use the following constructor:

template<class InputIterator> string (InputIterator begin, InputIterator end);

which would lead to something like:

std::vector<char> v;
std::string str(v.begin(), v.end());

My Swift 4 version of shouldChangeCharactersIn

func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange,
               replacementString string: String) -> Bool {

        guard let preText = textField.text as NSString?,
            preText.replacingCharacters(in: range, with: string).count <= MAX_TEXT_LENGTH else {
            return false
        }

        return true
    }

The problem is that you are trying to set the value of SecondTextField after checking every single character in the original string. You should do the conversion "on the side", one character at a time, and only then set the result into the SecondTextField.

As you go through the original string, start composing the output from an empty string. Keep appending the character in the opposite case until you run out of characters. Once the output is ready, set it into SecondTextField.

You can make an output a String, set it to an empty string "", and append characters to it as you go. This will work, but that is an inefficient approach. A better approach would be using a StringBuilder class, which lets you change the string without throwing away the whole thing.

First of all, install the prerequisite libraries:

sudo apt-get update
sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties libffi-dev

Then install rbenv, which is used to install Ruby:

cd
git clone https://github.com/rbenv/rbenv.git ~/.rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exec $SHELL

git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
exec $SHELL

rbenv install 2.3.1
rbenv global 2.3.1
ruby -v

Then (optional) tell Rubygems to not install local documentation:

echo "gem: --no-ri --no-rdoc" > ~/.gemrc

JQuery is looking for a json type result, but because the redirect is processed automatically, it will receive the generated html source of your login.htm page.

One idea is to let the the browser know that it should redirect by adding a redirect variable to to the resulting object and checking for it in JQuery:

$(document).ready(function(){ 
    jQuery.ajax({ 
        type: "GET", 
        url: "populateData.htm", 
        dataType:"json", 
        data:"userId=SampleUser", 
        success:function(response){ 
            if (response.redirect) {
                window.location.href = response.redirect;
            }
            else {
                // Process the expected results...
            }
        }, 
     error: function(xhr, textStatus, errorThrown) { 
            alert('Error!  Status = ' + xhr.status); 
         } 

    }); 
}); 

You could also add a Header Variable to your response and let your browser decide where to redirect. In Java, instead of redirecting, do response.setHeader("REQUIRES_AUTH", "1") and in JQuery you do on success(!):

//....
        success:function(response){ 
            if (response.getResponseHeader('REQUIRES_AUTH') === '1'){ 
                window.location.href = 'login.htm'; 
            }
            else {
                // Process the expected results...
            }
        }
//....

Hope that helps.

My answer is heavily inspired by this thread which shouldn't left any questions in case you still have some problems.

OK, after 2 years it's finally time to correct the syntax:

SELECT  t1.value, t2.value
FROM    MyTable t1
JOIN    MyTable t2
ON      t1.id = t2.id
WHERE   t1.id = @id
        AND t1.status = @status1
        AND t2.status = @status2

If you cannot utilize the ActiveDirectory Module or the Get-ADGroupMember cmdlet, you can do it with the LDAP "in chain"-matching rule:

$GroupDN = "CN=MyGroup,OU=Groups,DC=mydomain,DC=tld"
$LDAPFilter = "(&(objectClass=user)(objectCategory=Person)(memberOf:1.2.840.113556.1.4.1941:=$GroupDN))"

# Ideally using an instance of adsisearcher here:
Get-ADObject -LDAPFilter $LDAPFilter

See MSDN for additional LDAP matching rules implemented in Active Directory

You could use memset, if you sure about the length.

memset(ptr, 0x00, length)

Each jar version has a unique checksum. You can calculate the checksum for you jar (that had no version info) and compare it with the different versions of the jar. We can also search a jar using checksum.

Refer this Question to calculate checksum: What is the best way to calculate a checksum for a file that is on my machine?

As a one-liner into vim:

:set tabstop=4 shiftwidth=4

For permanent setup, add these lines to ~/.vimrc:

set tabstop=4
set shiftwidth=4

NOTE: Add set expandtab if you prefer 4-spaces indentation, instead of a tab indentation.

Try this SELECT DISTINCT 10 * ...

If (as I understand) you're trying to completely block inheritance in the web config of your child application, I suggest you to avoid using the tag in web.config. Instead create a new apppool and edit the applicationHost.config file (located in %WINDIR%\System32\inetsrv\Config and %WINDIR%\SysWOW64\inetsrv\config). You just have to find the entry for your apppool and add the attribute enableConfigurationOverride="false" like in the following example:

<add name="MyAppPool" autoStart="true" managedRuntimeVersion="v4.0" managedPipelineMode="Integrated" enableConfigurationOverride="false">
    <processModel identityType="NetworkService" />
</add>

This will avoid configuration inheritance in the applications served by MyAppPool.

I would recommend to use Calendar object and Locale since month names are different for different languages:

// index can be 0 - 11
private String getMonthName(final int index, final Locale locale, final boolean shortName)
{
    String format = "%tB";

    if (shortName)
        format = "%tb";

    Calendar calendar = Calendar.getInstance(locale);
    calendar.set(Calendar.MONTH, index);
    calendar.set(Calendar.DAY_OF_MONTH, 1);

    return String.format(locale, format, calendar);
}

Example for full month name:

System.out.println(getMonthName(0, Locale.US, false));

Result: January

Example for short month name:

System.out.println(getMonthName(0, Locale.US, true));

Result: Jan

paint.setStrokeWidth(3);

paint.setColor(BLACK);

and either one of your drawRect should work.

Use the literal escape character \

print("Here is, \"a quote\"")

The character basically means ignore the semantic context of my next charcter, and deal with it in its literal sense.

My approach seems to work, but is probably naive. Tell me why it is wrong.

ARGs set during docker build are exposed by the history subcommand, so no go there. However, when running a container, environment variables given in the run command are available to the container, but are not part of the image.

So, in the Dockerfile, do setup that does not involve secret data. Set a CMD of something like /root/finish.sh. In the run command, use environmental variables to send secret data into the container. finish.sh uses the variables essentially to finish build tasks.

To make managing the secret data easier, put it into a file that is loaded by docker run with the --env-file switch. Of course, keep the file secret. .gitignore and such.

For me, finish.sh runs a Python program. It checks to make sure it hasn't run before, then finishes the setup (e.g., copies the database name into Django's settings.py).

@John Woo's accepted answer has some caveats which you should be aware of:

1. Default language setting of a session is controlled from default language setting of the user login instead which you have used to create the session. SQL Server instance level setting doesn't affect the default language of the session.
2. Changing default language setting at SQL Server instance level doesn't affects the default language setting of the existing SQL Server logins. It is meant to be inherited only by the new user logins that you create after changing the instance level setting.

So, there is an intermediate level between your SQL Server instance and the session which you can use to control the default language setting for session - login level.

SQL Server Instance level setting -> User login level setting -> Query Session level setting

This can help you in case you want to set default language of all new sessions belonging to some specific user only.

Simply change the default language setting of the target user login as per this link and you are all set. You can also do it from SQL Server Management Studio (SSMS) UI. Below you can see the default language setting in properties window of sa user in SQL Server:

Note: Also, it is important to know that changing the setting doesn't affect the default language of already active sessions from that user login. It will affect only the new sessions created after changing the setting.

There's a solution:

import pyautogui
for i in range(1000):
    pyautogui.typewrite("a")

Here's a macro based on the one in the link posted by Wael, but improved in the following areas:

Installing libpq-dev did not work for me. I also needed to install build-essential

sudo apt-get install libpq-dev build-essential

try this:

ren "File 1-1" "File 1 - %date:/=-% %time::=-%"

Can the problem be with the "a.mProperty > b.mProperty" line? I've gotten the following code to work:

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

struct Foo
{
    Foo() : _i(0) {};

    int _i;

    friend std::ostream& operator<<(std::ostream& os, const Foo& f)
    {
        os << f._i;
        return os;
    };
};

typedef std::vector<Foo> VectorT;

std::string toString(const VectorT& v)
{
    std::stringstream ss;
    std::copy(v.begin(), v.end(), std::ostream_iterator<Foo>(ss, ", "));
    return ss.str();
};

int main()
{

    VectorT v(10);
    std::for_each(v.begin(), v.end(),
            [](Foo& f)
            {
                f._i = rand() % 100;
            });

    std::cout << "before sort: " << toString(v) << "\n";

    sort(v.begin(), v.end(),
            [](const Foo& a, const Foo& b)
            {
                return a._i > b._i;
            });

    std::cout << "after sort:  " << toString(v) << "\n";
    return 1;
};

The output is:

before sort: 83, 86, 77, 15, 93, 35, 86, 92, 49, 21,
after sort:  93, 92, 86, 86, 83, 77, 49, 35, 21, 15,

Put your domain name here: https://www.ssllabs.com/ssltest/analyze.html You should be able to see if there are any issues with your ssl certificate chain. I am guessing that you have SSL chain issues. A short description of the problem is that there's actually a list of certificates on your server (and not only one) and these need to be in the correct order. If they are there but not in the correct order, the website will be fine on desktop browsers (an iOs as well I think), but android is more strict about the order of certificates, and will give an error if the order is incorrect. To fix this you just need to re-order the certificates.

Using React on my IPad, type="number" does not work perfectly for me. For my floating point numbers in the range between 99.99999 - .00000 I use the regular expression (^[0-9]{0,2}$)|(^[0-9]{0,2}\.[0-9]{0,5}$). The first group (...) is true for all positive two digit numbers without the floating point (e.g. 23), | or e.g. .12345 for the second group (...). You can adopt it for any positive floating point number by simply changing the range {0,2} or {0,5} respectively.

<input
  className="center-align"
  type="text"
  pattern="(^[0-9]{0,2}$)|(^[0-9]{0,2}\.[0-9]{0,5}$)"
  step="any"
  maxlength="7"
  validate="true"
/>

You're getting into looping most likely due to these rules:

RewriteRule ^(.*\.php)$ $1 [L]
RewriteRule ^(wp-(content|admin|includes).*) $1 [L]

Just comment it out and try again in a new browser.

Swift 4 with saving array types

extension Array {
    func take(_ elementsCount: Int) -> [Element] {
        let min = Swift.min(elementsCount, count)
        return Array(self[0..<min])
    }
}

When you call startActivity on the last activity you could always use

Intent.FLAG_ACTIVITY_CLEAR_TOP

as a flag on that intent.

Read more about the flag here.

I use a slightly modified version of the "if DEBUG" style of settings that Harper Shelby posted. Obviously depending on the environment (win/linux/etc.) the code might need to be tweaked a bit.

I was in the past using the "if DEBUG" but I found that occasionally I needed to do testing with DEUBG set to False. What I really wanted to distinguish if the environment was production or development, which gave me the freedom to choose the DEBUG level.

PRODUCTION_SERVERS = ['WEBSERVER1','WEBSERVER2',]
if os.environ['COMPUTERNAME'] in PRODUCTION_SERVERS:
    PRODUCTION = True
else:
    PRODUCTION = False

DEBUG = not PRODUCTION
TEMPLATE_DEBUG = DEBUG

# ...

if PRODUCTION:
    DATABASE_HOST = '192.168.1.1'
else:
    DATABASE_HOST = 'localhost'

I'd still consider this way of settings a work in progress. I haven't seen any one way to handling Django settings that covered all the bases and at the same time wasn't a total hassle to setup (I'm not down with the 5x settings files methods).

You have to pass instance of MainActivity into another class, then you can call everything public (in MainActivity) from everywhere.

MainActivity.java

public class MainActivity extends AppCompatActivity {

    // Instance of AnotherClass for future use
    private AnotherClass anotherClass;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // Create new instance of AnotherClass and
        // pass instance of MainActivity by "this"
        anotherClass = new AnotherClass(this);
    }

    // Method you want to call from another class
    public void startChronometer(){
        ...
    }
}

AnotherClass.java

public class AnotherClass {

    // Main class instance
    private MainActivity mainActivity;  

    // Constructor
    public AnotherClass(MainActivity activity) {

        // Save instance of main class for future use
        mainActivity = activity;  

        // Call method in MainActivity
        mainActivity.startChronometer();
    }
}

Slight variation on the above instructions, worked for me. (MacOS Sierra 10.12.6)

npm install -g [email protected]
rm /usr/local/bin/npm
ln -s ~/.npm-packages/bin/npm /usr/local/bin/npm
npm --version

I don't have enough reputation to add in comments, so I just write some of my findings of this annoying TypeError here:

Basically, I think it's a bug in the json.dump() function in Python 2 only - It can't dump a Python (dictionary / list) data containing non-ASCII characters, even you open the file with the encoding = 'utf-8' parameter. (i.e. No matter what you do). But, json.dumps() works on both Python 2 and 3.

To illustrate this, following up phihag's answer: the code in his answer breaks in Python 2 with exception TypeError: must be unicode, not str, if data contains non-ASCII characters. (Python 2.7.6, Debian):

import json
data = {u'\u0430\u0431\u0432\u0433\u0434': 1} #{u'?????': 1}
with open('data.txt', 'w') as outfile:
    json.dump(data, outfile)

It however works fine in Python 3.

var myVar = null;

if(myVar)
   clearTimeout(myVar);

myVar = setTimeout(function(){ alert("Hello"); }, 3000);

if you're using a MacBook or UNIX based system, use this:

function wait(time)
if tonumber(time) ~= nil then
os.execute("Sleep "..tonumber(time))
else
os.execute("Sleep "..tonumber("0.1"))
end
wait()

In my case it was because I switched to master using

 git checkout -B master

Just to pull the new version of it instead of

 git checkout master

The first command resets the head of master to my latest commits

I used

git reset --hard origin/master

To fix that

I tried using it and didn't work, guess it's just the modal versioin.

Although, it worked as this:

$("#myModal").on("hide.bs.modal", function () {
    // put your default event here
});

Just to update the answer =)

Get jQuery up and running in a minute or less:

Insert this into your HTML (most commonly in the head, but you can throw it before the end body tag too):

<script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script>

Then place a script element after your jQuery one. This would alert 'hello' after the DOM is ready.

<script>$(function() { alert('hello') });</script>

Read the documentation.

Using jQuery locally:

After you get a feel, try downloading jQuery locally to your computer, and link it from your script file. The structure is like so:

C:/web/index.html
C:/web/js/jquery.js

index.html:

    <head>
        <script src="js/jquery.js"></script>
        <script>$(function() { alert('hi') })</script>
    </head>

You have the advantage of relying on your saved version offline if you don't have the Internet/Wi-Fi. You can also make custom edits to the jQuery source and modify it at will.

Study the jQuery source [advanced]

Download the uncompressed version from:

http://code.jquery.com/jquery-latest.js

After you've gained a bit of JavaScript/DOM knowledge try to take it apart step by step.

You can't use {{}} when using angular directives for binding with ng-model but for binding non-angular attributes you would have to use {{}}..

Eg:

ng-show="my-model"
title = "{{my-model}}"

For Integrattion with ECLIPSE LUNA in Windows 7 please foollow the below steps:

• Download the jar -> lombok-1.14.6.jar.

• Using command prompt go to java installed directory and type

  java -jar ${your_jar_path}\lombok-1.14.6.jar.
  

  Here ${your_jar_path} is your lombok-1.14.6.jar jar store directory.

• After this it will prompt for Eclipse already installed in your system and you need to select where you want to integrate.

• After this you need to open eclipse.ini file and make entry below

  -vmargs
  

  as

  -Xbootclasspath/a:lombok.jar
  -javaagent:lombok.jar
  

• Start your eclipse now and create a Maven project and make entry in pom.xml as mentioned below:

  <dependency>
      <groupId>org.projectlombok</groupId>
      <artifactId>lombok</artifactId>
      <version>1.14.6</version>
      <scope>provided</scope>
  </dependency>
  

After this your are ready to write your code and check it. Without @DATA annotation it looks like: With @DATA annotation it looks like:

An example i ran the command

C:\Program Files\Java\jdk1.7.0_75>java -jar C:\Users\Shareef-VM.m2\repository\o rg\projectlombok\lombok\1.14.8\lombok-1.14.8.jar

The proper way to install an MSI silently is via the msiexec.exe command line as follows:

msiexec.exe /i c:\setup.msi /QN /L*V "C:\Temp\msilog.log"

Quick explanation:

 /L*V "C:\Temp\msilog.log"= verbose logging
 /QN = run completely silently
 /i = run install sequence 

There is a much more comprehensive answer here: Batch script to install MSI. This answer provides details on the msiexec.exe command line options and a description of how to find the "public properties" that you can set on the command line at install time. These properties are generally different for each MSI.

It seems to me, this is a cross-domain issue since you're not allowed to make a request to a different domain.

You have to find solutions to this problem: - Use a proxy script, running on your server that will forward your request and will handle the response sending it to the browser Or - The service you're making the request should have JSONP support. This is a cross-domain technique. You might want to read this http://en.wikipedia.org/wiki/JSONP

UPDATE [TableName]
SET [ColumnName] = Replace([ColumnName], '[StringToRemove]', '[Replacement]')

In your instance it would be

UPDATE [TableName]
SET [ColumnName] = Replace([ColumnName], '[StringToRemove]', '')

Because there is no replacement (you want to get rid of it).

This will run on every row of the specified table. No need for a WHERE clause unless you want to specify only certain rows.

I know this is old and whatnot (and not exactly sure if it's a question), but after searching, I had success with this command for --onefile:

pyinstaller.exe --onefile --windowed --icon=app.ico app.py

Google led me to this page while I was searching for an answer on how to set an icon for my .exe, so maybe it will help someone else.

According to Oracle integration of OpenJDK & javaFX will be on Q1-2014 ( see roadmap : http://www.oracle.com/technetwork/java/javafx/overview/roadmap-1446331.html ). So, for the 1st question the answer is that you have to wait until then. For the 2nd question there is no other way. So, for now go with java swing or start javaFX and wait

The request object is not the session.

You want to use the session object to store. The session is added to the request and is were you want to persist data across requests. The session can be obtained from

HttpSession session = request.getSession(true);

Then you can use setAttribute or getAttribute on the session.

A more up to date tutorial on jsp sessions is: http://courses.coreservlets.com/Course-Materials/pdf/csajsp2/08-Session-Tracking.pdf

Let's imagine that u don't know how many strings there.

NSMutableArray *arrForStrings = [[NSMutableArray alloc] init];
for (int i=0; i<[allMyStrings count]; i++) {
    NSString *str = [allMyStrings objectAtIndex:i];
    [arrForStrings addObject:str];
}
NSString *readyString = [[arrForStrings mutableCopy] componentsJoinedByString:@", "];

Unmanaged object:

• Marshal.SizeOf(object yourObj);

Value Types:

• sizeof(object val)

Managed object:

• Looks like there is no direct way to get for managed objects, Ref: https://devblogs.microsoft.com/cbrumme/size-of-a-managed-object/

In build.gradle(Module:app) add this code

dependencies {
    ……..
    compile 'com.google.android.gms:play-services:10.0.1’
    ……  
}

If you still have a problem after that, then add this code in build.gradle(Module:app)

defaultConfig {
    ….
    …...
    multiDexEnabled true
}


dependencies {
    …..
    compile 'com.google.android.gms:play-services:10.0.1'
    compile 'com.android.support:multidex:1.0.1'
}

short answer: Array.from(string) will give you what you probably want and then you can iterate on it or whatever since it's just an array.

ok let's try it with this string: abc|??\n??|???.

codepoints are:

97
98
99
124
9899, 65039
10
9898, 65039
124
128104, 8205, 128105, 8205, 128103, 8205, 128103

so some characters have one codepoint (byte) and some have two or more, and a newline added for extra testing.

so after testing there are two ways:

• byte per byte (codepoint per codepoint)
• character groups (but not the whole family emoji)

string = "abc|??\n??|???"_x000D_
_x000D_
console.log({ 'string': string }) // abc|??\n??|???_x000D_
console.log({ 'string.length': string.length }) // 21_x000D_
_x000D_
for (let i = 0; i < string.length; i += 1) {_x000D_
  console.log({ 'string[i]': string[i] }) // byte per byte_x000D_
  console.log({ 'string.charAt(i)': string.charAt(i) }) // byte per byte_x000D_

_x000D_
for (let char of string) {_x000D_
  console.log({ 'for char of string': char }) // character groups_x000D_

string.replace(/./g, (char) => {_x000D_
  console.log({ 'string.replace(/./g, ...)': char }) // byte per byte_x000D_

_x000D_
string.replace(/[\S\s]/g, (char) => {_x000D_
  console.log({ 'string.replace(/[\S\s]/g, ...)': char }) // byte per byte_x000D_

Array.from(string).forEach((char) => {_x000D_
  console.log({ "Array.from(string).forEach": char }) // character groups_x000D_

var regexp = /(?:[\0-\uD7FF\uE000-\uFFFF]|[\uD800-\uDBFF][\uDC00-\uDFFF]|[\uD800-\uDBFF](?![\uDC00-\uDFFF])|(?:[^\uD800-\uDBFF]|^)[\uDC00-\uDFFF])/g_x000D_

If you removed the make all line from your "fresh" target:

fresh :
    rm -f *.o $(EXEC)
    clear

You could simply run the command make fresh all, which will execute as make fresh; make all.

Some might consider this as a second instance of make, but it's certainly not a sub-instance of make (a make inside of a make), which is what your attempt seemed to result in.

It's not a bug in ARel, it's a bug in your logic.

What you want here is:

Foo.includes(:bar).where(Bar.arel_table[:id].not_eq(nil))

This worked for me in Android Studio 3.6.3

Settings -> Build, Execution, Deployment -> Debugger -> Android Debug Bridge -> Enable 'Use libs backend'

One stupid mistake I did awhile ago that might help some people.

Keep in mind that if you are using ":" in an event like this, the value will not change

var ondrag = (function(event, ui) {
            ...

            nub0x: event.target.offsetLeft + event.target.clientWidth/2;
            nub0y = event.target.offsetTop + event.target.clientHeight/2;

            ...
        });

So "nub0x" will initialize with the first event that happens and will never change its value. But "nub0y" will change during the next events.

Variables in single-quotes are not evaluated. Use double quotes:

ssh [email protected] "~/tools/run_pvt.pl $BUILD_NUMBER"

The shell will expand variables in double-quotes, but not in single-quotes. This will change into your desired string before being passed to the ssh command.

#! /bin/bash
filetypes="*.py *.xml"
for type in $filetypes
do
find Documents -name "$type"
done

simple but works :)

I was also facing same error when I was inserting the data into HIVE external table which was pointing to Elastic search cluster.

I replaced the older JAR elasticsearch-hadoop-2.0.0.RC1.jar to elasticsearch-hadoop-5.6.0.jar, and everything worked fine.

My Suggestion is please use the specific JAR as per the elastic search version. Don't use older JARs if you are using newer version of elastic search.

Thanks to this post Hive- Elasticsearch Write Operation #409

I had an issue with my Apache configuration after installing a GoDaddy certificate on a subdomain. I originally thought it might be an issue with Node not sending a Server Name Indicator (SNI), but that wasn't the case. Analyzing the subdomain's SSL certificate with https://www.ssllabs.com/ssltest/ returned the error Chain issues: Incomplete.

After adding the GoDaddy provided gd_bundle-g2-g1.crt file via the SSLCertificateChainFile Apache directive, Node was able to connect over HTTPS and the error went away.

try

window.frameElement.ownerDocument.domain

The command build in pipeline is there to trigger other jobs in jenkins.

Example on github

The job must exist in Jenkins and can be parametrized. As for the branch, I guess you can read it from git

You use a shebang line at the start of your script:

#!/usr/bin/env python

make the file executable:

chmod +x arbitraryname

and put it in a directory on your PATH (can be a symlink):

cd ~/bin/
ln -s ~/some/path/to/myscript/arbitraryname

As per this the default is 2 MB for your <Connector>.

maxPostSize = The maximum size in bytes of the POST which will be handled by the container FORM URL parameter parsing. The limit can be disabled by setting this attribute to a value less than or equal to 0. If not specified, this attribute is set to 2097152 (2 megabytes).

Edit Tomcat's server.xml. In the <Connector> element, add an attribute maxPostSize and set a larger value (in bytes) to increase the limit.

Having said that, if this is the issue, you should have got an exception on the lines of Post data too big in tomcat

For Further Info

You should be able to find your command with a ps variant like:

ps -ef
ps -fubob # if your job's user ID is bob.

Then, once located, it should be a simple matter to use kill to kill the process (permissions permitting).

If you're talking about getting rid of jobs in the at queue (that aren't running yet), you can use atq to list them and atrm to get rid of them.

Currently I'm using this solution:

$firstDay = new \DateTime('first day of this month');
$lastDay = new \DateTime('last day of this month');

The only issue I came upon is that strange time is being set. I needed correct range for our search interface and I ended up with this:

$firstDay = new \DateTime('first day of this month 00:00:00');
$lastDay = new \DateTime('first day of next month 00:00:00');

As session.query(SomeModel.col1) returns an array of tuples like this [('value_1',),('value_2',)] if you want t cast the result to a plain array you can do it by using one of the following statements:

values = [value[0] for value in session.query(SomeModel.col1)]
values = [model.col1 for model in session.query(SomeModel).options(load_only('col1'))]

Result:

 ['value_1', 'value_2']

You can easily get child itself and all of its decedents (children) with Jquery's Clone() method, just

var child = $('#div div:nth-child(1)').clone();  

var child2 = $('#div div:nth-child(2)').clone();

You will get this for first query as asked in question

<div id="div1">
     <p>Some Content</p>
</div>

If you get this error under Linux when running conda using sudo, you might be suffering from bug #7267:

When logging in as non-root user via sudo, e.g. by:

sudo -u myuser -i

conda seems to assume that it is run as root and raises an error.

The only known workaround seems to be: Add the following line to your ~/.bashrc:

unset SUDO_UID SUDO_GID SUDO_USER

...or unset the ENV variables by running the line in a different way before running conda.

If you mistakenly installed anaconda/miniconda as root/via sudo this can also lead to the same error, then you might want to do the following:

sudo chown -R username /path/to/anaconda3

Tested with conda 4.6.14.

By using display: inline-block; And more generally when you have a parent (always there is a parent except for html) use display: inline-block; for the inner elements. and to force them to stay in the same line even when the window get shrunk (contracted). Add for the parent the two property:

    white-space: nowrap;
    overflow-x: auto;

here a more formatted example to make it clear:

.parent {
    white-space: nowrap;
    overflow-x: auto;
}

.children {
   display: inline-block;
   margin-left: 20px; 
}

For this example particularly, you can apply the above as fellow (i'm supposing the parent is body. if not you put the right parent), you can also like change the html and add a parent for them if it's possible.

body { /*body may pose problem depend on you context, there is no better then have a specific parent*/
        white-space: nowrap;
        overflow-x: auto;
 }

#element1, #element2{ /*you can like put each one separately, if the margin for the first element is not wanted*/
   display: inline-block;
   margin-left: 10px; 
}

keep in mind that white-space: nowrap; and overlow-x: auto; is what you need to force them to be in one line. white-space: nowrap; disable wrapping. And overlow-x:auto; to activate scrolling, when the element get over the frame limit.

Per the source:

After connecting:

Db.authenticate(user, password, function(err, res) {
  // callback
});

Just wanted to add -- apparently this can also be caused by installing Instant Client for 10, then realizing you want the full install and installing it again in a parallel directory. I don't know why this broke it.

Just use a set. Its semantics are exactly what you want: a collection of unique items.

Technically you'll be iterating through the list twice: once to create the set, once for your actual loop. But you'd be doing just as much work or more with any other approach.

Basically single precision floating point arithmetic deals with 32 bit floating point numbers whereas double precision deals with 64 bit.

The number of bits in double precision increases the maximum value that can be stored as well as increasing the precision (ie the number of significant digits).

One easy way to select random items is to shuffle then slice.

import random
a = [1,2,3,4,5,6,7,8,9]
random.shuffle(a)
print a[:4] # prints 4 random variables

This might be what you're looking for: Xcode Organizer

you have to check your pip package to be updated to the latest version in your pycharm and then install numpy package. in settings -> project:progLangComp -> Project Interpreter there is a table of packages and their current version (just labelled as Version) and their latest version (labelled as Latest). Pip current version number should be the same as latest version. If you see a blue arrow in front of pip, you have to update it to the latest then trying to install numpy or any other packages that you couldn't install, for me it was pandas which I wanted to install.

You can convert the QString type to python string by just using the str function. Assuming you are not using any Unicode characters you can get a python string as below:

text = str(combobox1.currentText())

If you are using any unicode characters, you can do:

text = unicode(combobox1.currentText())

get() returns a single object. If there is no existing object to return, you will receive <class>.DoesNotExist. If your query returns more than one object, then you will get MultipleObjectsReturned. You can check here for more details about get() queries.

Similarly, Django will complain if more than one item matches the get() query. In this case, it will raise MultipleObjectsReturned, which again is an attribute of the model class itself.

M2M will return any number of query that it is related to. In this case you can receive zero, one or more items with your query.

In your models you can us following:

for _topic in topic.objects.all():
    _topic.learningobjective_set.all()

you can use _set to execute a select query on M2M. In above case, you will filter all learningObjectives related to each topic

If you needed to add a lot of integers it'd proabbly be easiest to use a for loop. For example, adding 28 days to a daysInFebruary array.

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

for(int i = 1; i <= 28; i++) {
    daysInFebruary.add(i);
}

A file cannot be uploaded using AJAX because you cannot access the contents of a file stored on the client computer and send it in the request using javascript. One of the techniques to achieve this is to use hidden iframes. There's a nice jquery form plugin which allows you to AJAXify your forms and it supports file uploads as well. So using this plugin your code will simply look like this:

$(function() {
    $('#ifoftheform').ajaxForm(function(result) {
        alert('the form was successfully processed');
    });
});

The plugin automatically takes care of subscribing to the submit event of the form, canceling the default submission, serializing the values, using the proper method and handle file upload fields, ...

Though you certainly can build such a device out of existing sequence operators, I would in this case be inclined to write this one up as a custom sequence operator. Something like:

// Returns "other" if the list is empty.
// Returns "other" if the list is non-empty and there are two different elements.
// Returns the element of the list if it is non-empty and all elements are the same.
public static int Unanimous(this IEnumerable<int> sequence, int other)
{
    int? first = null;
    foreach(var item in sequence)
    {
        if (first == null)
            first = item;
        else if (first.Value != item)
            return other;
    }
    return first ?? other;
}

That's pretty clear, short, covers all the cases, and does not unnecessarily create extra iterations of the sequence.

Making this into a generic method that works on IEnumerable<T> is left as an exercise. :-)

Yes, it is possible!

» JavaScript

if?=()=>!0;_x000D_
var a = 9;_x000D_

if?(a==1 && a== 2 && a==3)_x000D_
{_x000D_
    document.write("<h1>Yes, it is possible!</h1>")_x000D_
}

The above code is a short version (thanks to @Forivin for its note in comments) and the following code is original:

var a = 9;_x000D_
_x000D_
if?(a==1 && a== 2 && a==3)_x000D_
{_x000D_
    //console.log("Yes, it is possible!")_x000D_

If you just see top side of my code and run it you say WOW, how?

So I think it is enough to say Yes, it is possible to someone that said to you: Nothing is impossible

Trick: I used a hidden character after if to make a function that its name is similar to if. In JavaScript we can not override keywords so I forced to use this way. It is a fake if, but it works for you in this case!

» C#

Also I wrote a C# version (with increase property value technic):

static int _a;
public static int a => ++_a;

public static void Main()
{
    if(a==1 && a==2 && a==3)
    {
        Console.WriteLine("Yes, it is possible!");
    }
}

I already wrote a function for one of my projects that will comparing an object as a user options with its internal clone. It also can validate and even replace by default values if the user entered bad type of data or removed, in pure javascript.

Typical error on Windows because the default user directory is C:\user\<your_user>, so when you want to use this path as an string parameter into a Python function, you get a Unicode error, just because the \u is a Unicode escape. Any character not numeric after this produces an error.

To solve it, just double the backslashes: C:\\user\\<\your_user>...

Take a look at the ATI Stream Computing SDK. It is based on BrookGPU developed at Stanford.

In the future all GPU work will be standardized using OpenCL. It's an Apple-sponsored initiative that will be graphics card vendor neutral.

Particularly when using something like Twitter's Bootstrap, white-space: nowrap; doesn't always work in CSS when applying padding or margin to a child div. Instead however, adding an equivalent border: 20px solid transparent; style in place of padding/margin works more consistently.

In case you don't need javax.el (for example in a JavaSE application), use ParameterMessageInterpolator from Hibernate validator. Hibernate validator is a standalone component, which can be used without Hibernate itself.

Depend on hibernate-validator

<dependency>
   <groupId>org.hibernate</groupId>
   <artifactId>hibernate-validator</artifactId>
   <version>6.0.16.Final</version>
</dependency>

Use ParameterMessageInterpolator

import javax.validation.Validation;
import javax.validation.Validator;
import org.hibernate.validator.messageinterpolation.ParameterMessageInterpolator;

private static final Validator VALIDATOR =
  Validation.byDefaultProvider()
    .configure()
    .messageInterpolator(new ParameterMessageInterpolator())
    .buildValidatorFactory()
    .getValidator();

The execmgr.log will show the commandline and ccmcache folder used for installation. Typically, required apps don't show on appenforce.log and some clients will have outdated appenforce or no ppenforce.log files. execmgr.log also shows required hidden uninstall actions as well.

You may want to save the blog link. I still reference it from time to time.

Or you can use:

Start /d "the directory of the executable" /b "the name of the executable" "parameters of the executable" %1

If %1 is a file then it is passed to your executable. For example in notepad.exe foo.txt %1 is "foo.txt".

The /b parameter of the start command does this:

Starts an application without opening a new Command Prompt window. CTRL+C handling is ignored unless the application enables CTRL+C processing. Use CTRL+BREAK to interrupt the application.

Which is exactly what we want.

In getting started with require.js I ran into the issue and as a beginner the docs may as well been written in greek.

The issue I ran into was that most of the beginner examples use "anonymous defines" when you should be using a "string id".

anonymous defines

define(function() {
        return { helloWorld: function() { console.log('hello world!') } };
 })
    
  
define(function() {
        return { helloWorld2: function() { console.log('hello world again!') } };
 })

define with string id

define('moduleOne',function() {
    return { helloWorld: function() { console.log('hello world!') } };
})

 define('moduleTwo', function() {
      return { helloWorld2: function() { console.log('hello world again!') } };
})

When you use define with a string id then you will avoid this error when you try to use the modules like so:

require([ "moduleOne", "moduleTwo" ], function(moduleOne, moduleTwo) {
    moduleOne.helloWorld();
    moduleTwo.helloWorld2();
});

Using Kotlin:

You can create an extension function or just use setCompoundDrawablesWithIntrinsicBounds directly.

fun TextView.leftDrawable(@DrawableRes id: Int = 0) {
   this.setCompoundDrawablesWithIntrinsicBounds(id, 0, 0, 0)
}

If you need to resize the drawable, you can use this extension function.

textView.leftDrawable(R.drawable.my_icon, R.dimen.icon_size)

fun TextView.leftDrawable(@DrawableRes id: Int = 0, @DimenRes sizeRes: Int) {
    val drawable = ContextCompat.getDrawable(context, id)
    val size = resources.getDimensionPixelSize(sizeRes)
    drawable?.setBounds(0, 0, size, size)
    this.setCompoundDrawables(drawable, null, null, null)
}

To get really fancy, create a wrapper that allows size and/or color modification.

textView.leftDrawable(R.drawable.my_icon, colorRes = R.color.white)

fun TextView.leftDrawable(@DrawableRes id: Int = 0, @DimenRes sizeRes: Int = 0, @ColorInt color: Int = 0, @ColorRes colorRes: Int = 0) {
    val drawable = drawable(id)
    if (sizeRes != 0) {
        val size = resources.getDimensionPixelSize(sizeRes)
        drawable?.setBounds(0, 0, size, size)
    }
    if (color != 0) {
        drawable?.setColorFilter(color, PorterDuff.Mode.SRC_ATOP)
    } else if (colorRes != 0) {
        val colorInt = ContextCompat.getColor(context, colorRes)
        drawable?.setColorFilter(colorInt, PorterDuff.Mode.SRC_ATOP)
    }
    this.setCompoundDrawables(drawable, null, null, null)
}

I would think that now you have the range for each of the row, you can easily manipulate that range with the offset(row, column) action? What is the point of counting the records filtered (unless you need that count in a variable)? So instead of (or as well as in the same block) write your code action to move each row to an empty hidden sheet and once all done, you can do any work you like from the transferred range data?

You can use PHP strtr() function to get rid of accented characters :

$string = "Éric Cantona";
$accented_array = array('Š'=>'S', 'š'=>'s', 'Ž'=>'Z', 'ž'=>'z', 'À'=>'A', 'Á'=>'A', 'Â'=>'A', 'Ã'=>'A', 'Ä'=>'A', 'Å'=>'A', 'Æ'=>'A', 'Ç'=>'C', 'È'=>'E', 'É'=>'E','Ê'=>'E', 'Ë'=>'E', 'Ì'=>'I', 'Í'=>'I', 'Î'=>'I', 'Ï'=>'I', 'Ñ'=>'N', 'Ò'=>'O', 'Ó'=>'O', 'Ô'=>'O', 'Õ'=>'O', 'Ö'=>'O', 'Ø'=>'O', 'Ù'=>'U','Ú'=>'U', 'Û'=>'U', 'Ü'=>'U', 'Ý'=>'Y', 'Þ'=>'B', 'ß'=>'Ss', 'à'=>'a', 'á'=>'a', 'â'=>'a', 'ã'=>'a', 'ä'=>'a', 'å'=>'a', 'æ'=>'a', 'ç'=>'c','è'=>'e', 'é'=>'e', 'ê'=>'e', 'ë'=>'e', 'ì'=>'i', 'í'=>'i', 'î'=>'i', 'ï'=>'i', 'ð'=>'o', 'ñ'=>'n', 'ò'=>'o', 'ó'=>'o', 'ô'=>'o', 'õ'=>'o','ö'=>'o', 'ø'=>'o', 'ù'=>'u', 'ú'=>'u', 'û'=>'u', 'ý'=>'y', 'þ'=>'b', 'ÿ'=>'y' );

$required_str = strtr( $string, $accented_array );

select   UserId,max(Date) over (partition by UserId) value from users;

Use the BinaryFormatter:

byte[] ObjectToByteArray(object obj)
{
    if(obj == null)
        return null;
    BinaryFormatter bf = new BinaryFormatter();
    using (MemoryStream ms = new MemoryStream())
    {
        bf.Serialize(ms, obj);
        return ms.ToArray();
    }
}

Note that obj and any properties/fields within obj (and so-on for all of their properties/fields) will all need to be tagged with the Serializable attribute to successfully be serialized with this.

You mean the ASCII ordinal value? Try type casting like this one:

int x = 'a';

you need /q at the end

MsiExec.exe /x {2F808931-D235-4FC7-90CD-F8A890C97B2F} /q

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:

;setlocal ENABLEEXTENSIONS
;rem make from X.bat a X.ps1 by removing all lines starting with ';' 
;Findstr -rbv "^[;]" %0 > %~dpn0.ps1 
;powershell -ExecutionPolicy Unrestricted -File %~dpn0.ps1 %*
;del %~dpn0.ps1
;endlocal
;goto :EOF
;rem Here start your power shell script.
param(
    ,[switch]$help
)

If you want to consider null values equality too, try the following

select column1, column2, 
   case
      when column1 is NULL and column2 is NULL then 'true'  
      when column1=column2 then 'true' 
      else 'false' 
   end 
from table;

In Intellinj IDEA 14, we can change the Git password by the following steps:

From the menu bar :

1. Select File -> Settings -> Appearance & Behavior -> System Settings .

2. Choose Passwords.

3. Click the 'Master Password' under 'Disk storage protection'.

4. In the Password field, enter your old password. Enter your new password in the subsequent fields.

5. Now the master password will be changed.

A plugin is probably your best option. Look in the wordpress plugins directory or google to see if you can find one. I found the one below and that seemed to work perfect.

With Aspose.Cells library for .NET, you can easily export data of specific rows and columns from one Excel document to another. The following code sample shows how to do this in C# language.

// Open the source excel file.
Workbook srcWorkbook = new Workbook("Source_Workbook.xlsx");

// Create the destination excel file.
Workbook destWorkbook = new Workbook();
   
// Get the first worksheet of the source workbook.
Worksheet srcWorksheet = srcWorkbook.Worksheets[0];

// Get the first worksheet of the destination workbook.
Worksheet desWorksheet = destWorkbook.Worksheets[0];

// Copy the second row of the source Workbook to the first row of destination Workbook.
desWorksheet.Cells.CopyRow(srcWorksheet.Cells, 1, 0);

// Copy the fourth row of the source Workbook to the second row of destination Workbook.
desWorksheet.Cells.CopyRow(srcWorksheet.Cells, 3, 1);

// Save the destination excel file.
destWorkbook.Save("Destination_Workbook.xlsx");

The following blog post explains in detail how to export data from different sources to an Excel document.

My requirement was slightly different than the question, still this is also a useful way of stopping the thread to be executing its tasks. All I wanted to do is to stop the thread on exiting the screen and resumes while returning to the screen.

As per the Android docs, this would be the proposed replacement for stop method which has been deprecated from API 15

Many uses of stop should be replaced by code that simply modifies some variable to indicate that the target thread should stop running. The target thread should check this variable regularly, and return from its run method in an orderly fashion if the variable indicates that it is to stop running.

My Thread class

   class ThreadClass implements Runnable {
            ...
                  @Override
                        public void run() {
                            while (count < name.length()) {

                                if (!exited) // checks boolean  
                                  {
                                   // perform your task
                                                     }
            ...

OnStop and OnResume would look like this

  @Override
    protected void onStop() {
        super.onStop();
        exited = true;
    }

    @Override
    protected void onResume() {
        super.onResume();
        exited = false;
    }

This accomplishes the same thing but is much simpler:

$(document).ready(function() {  
   $("#board").delay(1000).append(".");
});

You can chain a delay before almost any jQuery method.

In my case I selected application pool with .NET Framework 2.0 and enabled 32-bit application. I had .NET Framework 2.0 application.

The accepted answer being said, It is missing some explanations. For example, what is the difference between a uni-directional and a bi-directional association? In the provided example, both do exist. ( Both '5's in the arrows)

If looking for a more complete answer and have more time, here is a thorough explanation.

You could use CodeSmith to generate something like this:

http://www.csharping.com/PermaLink,guid,cef1b637-7d37-4691-8e49-138cbf1d51e9.aspx

You need to put it in the join clause, not the where:

SELECT *
FROM categories
LEFT JOIN user_category_subscriptions ON 
    user_category_subscriptions.category_id = categories.category_id
    and user_category_subscriptions.user_id =1

See, with an inner join, putting a clause in the join or the where is equivalent. However, with an outer join, they are vastly different.

As a join condition, you specify the rowset that you will be joining to the table. This means that it evaluates user_id = 1 first, and takes the subset of user_category_subscriptions with a user_id of 1 to join to all of the rows in categories. This will give you all of the rows in categories, while only the categories that this particular user has subscribed to will have any information in the user_category_subscriptions columns. Of course, all other categories will be populated with null in the user_category_subscriptions columns.

Conversely, a where clause does the join, and then reduces the rowset. So, this does all of the joins and then eliminates all rows where user_id doesn't equal 1. You're left with an inefficient way to get an inner join.

Hopefully this helps!

A quick answer:

mvn -fn test

Works with nested project builds.

I faced this issue on GCP while deploying wordpress in the App Engine Standard environment. This solved it :

sudo apt-get install php7.2-zip

Let df be the data frame with 2 fields A and B

Case 1: if your field A and B are numeric

df[order(df[,1],df[,2]),] - sorts fields A and B in ascending order
df[order(df[,1],-df[,2]),] - sorts fields A in ascending and B in descending order
priority is given to A.

Case 2: if field A or B is non numeric say factor or character

In our case if B is character and we want to sort in reverse order
df[order(df[,1],-as.numeric(as.factor(df[,2]))),] -> this sorts field A(numerical) in ascending and field B(character) in descending.
priority is given to A.

The idea is that you can apply -sign in order function ony on numericals. So for sorting character strings in descending order you have to coerce them to numericals.

If the server sends some status code different than 200, the error callback is executed:

$.ajax({
    url: '/foo',
    success: function(result) {
        alert('yeap');
    },
    error: function(XMLHttpRequest, textStatus, errorThrown) {
        alert('oops, something bad happened');
    }
});

and to register a global error handler you could use the $.ajaxSetup() method:

$.ajaxSetup({
    error: function(XMLHttpRequest, textStatus, errorThrown) {
        alert('oops, something bad happened');
    }
});

Another way is to use JSON. So you could write a custom action filter on the server which catches exception and transforms them into JSON response:

public class MyErrorHandlerAttribute : FilterAttribute, IExceptionFilter
{
    public void OnException(ExceptionContext filterContext)
    {
        filterContext.ExceptionHandled = true;
        filterContext.Result = new JsonResult
        {
            Data = new { success = false, error = filterContext.Exception.ToString() },
            JsonRequestBehavior = JsonRequestBehavior.AllowGet
        };
    }
}

and then decorate your controller action with this attribute:

[MyErrorHandler]
public ActionResult Foo(string id)
{
    if (string.IsNullOrEmpty(id))
    {
        throw new Exception("oh no");
    }
    return Json(new { success = true });
}

and finally invoke it:

$.getJSON('/home/foo', { id: null }, function (result) {
    if (!result.success) {
        alert(result.error);
    } else {
        // handle the success
    }
});

The UDF approach is my preference compared to brittle substr values.

#!/usr/bin/env python3

from dateutil import parser
from pprint import pprint


def date_parse(s):
    ''' Converts a string to a date '''
    try:

        return t.strftime('%Y-%m-%d')

        d[col[0]] = row[idx]
    return d


def main():
    ''' Demonstrate UDF '''

        conn.row_factory = dict_factory
        setup(conn)

    cur.execute(sql)

    # Fill the table
    dates = [
        '2/1/03', '03/2/04', '4/03/05', '05/04/06',
        '6/5/2007', '07/6/2008', '8/07/2009', '09/08/2010',

This will give you these results:

 {'date': '2-1-03', 'parsed': '2003-01-02'},

 {'date': '31-12-2020', 'parsed': '2020-12-31'}]

The SQLite equivalent of anything this robust is a tangled weave of substr and instr calls that you should avoid.

It's hard to escape a single quote within single quotes. Try this:

sed "s@['\"]http://www.\([^.]\+).com['\"]@URL_\U\1@g" 

Example:

$ sed "s@['\"]http://www.\([^.]\+\).com['\"]@URL_\U\1@g" <<END
this is "http://www.fubar.com" and 'http://www.example.com' here
END

produces

this is URL_FUBAR and URL_EXAMPLE here

As other have said, TRUNCATE TABLE is far quicker, but it does have some restrictions (taken from here):

You cannot use TRUNCATE TABLE on tables that:

- Are referenced by a FOREIGN KEY constraint. (You can truncate a table that has a foreign key that references itself.)
- Participate in an indexed view.
- Are published by using transactional replication or merge replication.

For tables with one or more of these characteristics, use the DELETE statement instead.

The biggest drawback is that if the table you are trying to empty has foreign keys pointing to it, then the truncate call will fail.

I am not going to give you the whole answer (I don't think you're looking for the parsing and writing to file part anyway), but a pivotal hint should suffice: use python's set() function, and then sorted() or .sort() coupled with .reverse():

>>> a=sorted(set([10,60,30,10,50,20,60,50,60,10,30]))
>>> a
[10, 20, 30, 50, 60]
>>> a.reverse()
>>> a
[60, 50, 30, 20, 10]

For debugging purposes one could open the console, change the execution context to the frame that he wants refreshed, and do document.location.reload()

Without code and mappings for your transactions, it'll be next to impossible to investigate the problem.

However, to get a better handle as to what causes the problem, try the following:

• In your hibernate configuration, set hibernate.show_sql to true. This should show you the SQL that is executed and causes the problem.
• Set the log levels for Spring and Hibernate to DEBUG, again this will give you a better idea as to which line causes the problem.
• Create a unit test which replicates the problem without configuring a transaction manager in Spring. This should give you a better idea of the offending line of code.

Hope that helps.

The same document says

Unlike simple requests (discussed above), "preflighted" requests first send an HTTP OPTIONS request header to the resource on the other domain, in order to determine whether the actual request is safe to send. Cross-site requests are preflighted like this since they may have implications to user data. In particular, a request is preflighted if:

It uses methods other than GET or POST. Also, if POST is used to send request data with a Content-Type other than application/x-www-form-urlencoded, multipart/form-data, or text/plain, e.g. if the POST request sends an XML payload to the server using application/xml or text/xml, then the request is preflighted.

It sets custom headers in the request (e.g. the request uses a header such as X-PINGOTHER)

When the original request is Get with no custom headers, the browser should not make Options request which it does now. The problem is it generates a header X-Requested-With which forces the Options request. See https://github.com/angular/angular.js/pull/1454 on how to remove this header

Try this:

String text = mySpinner.getSelectedItem().toString();

Like this you can get value for different Spinners.

EDIT: For a better description, see x86 Disassembly/Functions and Stack Frames in a WikiBook about x86 assembly. I try to add some info you might be interested in using Visual Studio.

Storing the caller EBP as the first local variable is called a standard stack frame, and this may be used for nearly all calling conventions on Windows. Differences exist whether the caller or callee deallocates the passed parameters, and which parameters are passed in registers, but these are orthogonal to the standard stack frame problem.

Speaking about Windows programs, you might probably use Visual Studio to compile your C++ code. Be aware that Microsoft uses an optimization called Frame Pointer Omission, that makes it nearly impossible to do walk the stack without using the dbghlp library and the PDB file for the executable.

This Frame Pointer Omission means that the compiler does not store the old EBP on a standard place and uses the EBP register for something else, therefore you have hard time finding the caller EIP without knowing how much space the local variables need for a given function. Of course Microsoft provides an API that allows you to do stack-walks even in this case, but looking up the symbol table database in PDB files takes too long for some use cases.

To avoid FPO in your compilation units, you need to avoid using /O2 or need to explicitly add /Oy- to the C++ compilation flags in your projects. You probably link against the C or C++ runtime, which uses FPO in the Release configuration, so you will have hard time to do stack walks without the dbghlp.dll.

step 1: delete virtualenv virtualenvwrapper by copy and paste the following command below:

$ sudo pip uninstall virtualenv virtualenvwrapper

step 2: go to .bashrc and delete all virtualenv and virtualenvwrapper

open terminal:

$ sudo nano .bashrc

scroll down and you will see the code bellow then delete it.

# virtualenv and virtualenvwrapper
export WORKON_HOME=$HOME/.virtualenvs
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
source /usr/local/bin/virtualenvwrapper.sh

next, source the .bashrc:

$ source ~/.bashrc

FINAL steps: without terminal/shell go to /home and find .virtualenv (I forgot the name so if your find similar to .virtualenv or .venv just delete it. That will work.

Based on Yannuth's answer but simplified.

Here, length of dest[] is implied to be twice of len, and its allocation is managed by the caller.

void create_hex_string_implied(const unsigned char *src, size_t len, unsigned char *dest)
{
    static const unsigned char table[] = "0123456789abcdef";

    for (; len > 0; --len)
    {
        unsigned char c = *src++;
        *dest++ = table[c >> 4];
        *dest++ = table[c & 0x0f];
    }
}

A way to get this can be print multiple end of lines ("\n") and simulate the clear screen. At the end clear, at most in the unix shell, not removes the previous content, only moves it up and if you make scroll down can see the previous content.

Here is a sample code:

for (int i = 0; i < 50; ++i) System.out.println();

Try using double quotes and keeping the L in location lowercase...

header("location: http://linkhere.com/HERE_I_WANT_THE_VARIABLE");

or for example

header("location: http://linkhere.com/$variable");

No need to concatenate here to insert variables.

In the codebase I'm working with (1 million + lines of code) we had a problem with long startup times, around 60 seconds. We were getting 12000+ FactoryBeanNotInitializedException.

What I did was set a conditional breakpoint in AbstractBeanFactory#doGetBean

catch (BeansException ex) {
   // Explicitly remove instance from singleton cache: It might have been put there
   // eagerly by the creation process, to allow for circular reference resolution.
   // Also remove any beans that received a temporary reference to the bean.
   destroySingleton(beanName);
   throw ex;
}

where it does destroySingleton(beanName) I printed the exception with conditional breakpoint code:

   System.out.println(ex);
   return false;

Apparently this happens when FactoryBeans are involved in a cyclic dependency graph. We solved it by implementing ApplicationContextAware and InitializingBean and manually injecting the beans.

import org.springframework.beans.BeansException;
import org.springframework.beans.factory.InitializingBean;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;

public class A implements ApplicationContextAware, InitializingBean{

    private B cyclicDepenency;
    private ApplicationContext ctx;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext)
            throws BeansException {
        ctx = applicationContext;
    }
    @Override
    public void afterPropertiesSet() throws Exception {
        cyclicDepenency = ctx.getBean(B.class);
    }

    public void useCyclicDependency()
    {
        cyclicDepenency.doSomething();
    }
}

This cut down the startup time to around 15 secs.

So don't always assume that spring can be good at solving these references for you.

For this reason I'd recommend disabling cyclic dependency resolution with AbstractRefreshableApplicationContext#setAllowCircularReferences(false) to prevent many future problems.

I think that Alex Martelli's answer is definitely the most elegant way to do this, but just wanted to add a way to satisfy your want for a super awesome dictionary.filter(f) method in a Pythonic sort of way:

class FilterDict(dict):
    def __init__(self, input_dict):
        for key, value in input_dict.iteritems():
            self[key] = value
    def filter(self, criteria):
        for key, value in self.items():
            if (criteria(value)):
                self.pop(key)

my_dict = FilterDict( {'a':(3,4), 'b':(1,2), 'c':(5,5), 'd':(3,3)} )
my_dict.filter(lambda x: x[0] < 5 and x[1] < 5)

Basically we create a class that inherits from dict, but adds the filter method. We do need to use .items() for the the filtering, since using .iteritems() while destructively iterating will raise exception.

Using Pillow (which works with Python 3.X as well as Python 2.7+), you can do the following:

from PIL import Image
im = Image.open('image.jpg', 'r')
width, height = im.size
pixel_values = list(im.getdata())

Now you have all pixel values. If it is RGB or another mode can be read by im.mode. Then you can get pixel (x, y) by:

pixel_values[width*y+x]

Alternatively, you can use Numpy and reshape the array:

>>> pixel_values = numpy.array(pixel_values).reshape((width, height, 3))
>>> x, y = 0, 1
>>> pixel_values[x][y]
[ 18  18  12]

A complete, simple to use solution is

# Third party modules
import numpy
from PIL import Image


def get_image(image_path):
    """Get a numpy array of an image so that one can access values[x][y]."""
    image = Image.open(image_path, "r")
    width, height = image.size
    pixel_values = list(image.getdata())
    if image.mode == "RGB":
        channels = 3
    elif image.mode == "L":
        channels = 1
    else:
        print("Unknown mode: %s" % image.mode)
        return None
    pixel_values = numpy.array(pixel_values).reshape((width, height, channels))
    return pixel_values


image = get_image("gradient.png")

print(image[0])
print(image.shape)

Smoke testing the code

You might be uncertain about the order of width / height / channel. For this reason I've created this gradient:

The image has a width of 100px and a height of 26px. It has a color gradient going from #ffaa00 (yellow) to #ffffff (white). The output is:

[[255 172   5]
 [255 172   5]
 [255 172   5]
 [255 171   5]
 [255 172   5]
 [255 172   5]
 [255 171   5]
 [255 171   5]
 [255 171   5]
 [255 172   5]
 [255 172   5]
 [255 171   5]
 [255 171   5]
 [255 172   5]
 [255 172   5]
 [255 172   5]
 [255 171   5]
 [255 172   5]
 [255 172   5]
 [255 171   5]
 [255 171   5]
 [255 172   4]
 [255 172   5]
 [255 171   5]
 [255 171   5]
 [255 172   5]]
(100, 26, 3)

Things to note:

• The shape is (width, height, channels)
• The image[0], hence the first row, has 26 triples of the same color

Note: I am running SQL 2016 Developer 64bit, Office 2016 64bit.

I had the same issue and solved it by downloading the following:

1. Download and install this: https://www.microsoft.com/en-us/download/details.aspx?id=54920

2. Whatever file you are trying to access/import, make sure you select it as a Office 2010 file (even though it might be a Office 2016 file).

It works.

Source

You can append the text to $0 in awk if it matches the condition:

awk '/^all:/ {$0=$0" anotherthing"} 1' file

Explanation

• /patt/ {...} if the line matches the pattern given by patt, then perform the actions described within {}.
• In this case: /^all:/ {$0=$0" anotherthing"} if the line starts (represented by ^) with all:, then append anotherthing to the line.
• 1 as a true condition, triggers the default action of awk: print the current line (print $0). This will happen always, so it will either print the original line or the modified one.

Test

For your given input it returns:

somestuff...
all: thing otherthing anotherthing
some other stuff

Note you could also provide the text to append in a variable:

$ awk -v mytext=" EXTRA TEXT" '/^all:/ {$0=$0mytext} 1' file
somestuff...
all: thing otherthing EXTRA TEXT
some other stuff

Is it a console program, running in Windows? If so, run it from a console you've already opened. i.e. run "cmd", then change to your directory that has the .exe in it (using the cd command), then type in the exe name. Your console window will stay open.

I'd argue that most of the solutions shown here suffer from being over-engineerd. Probably the most simple way to check if a value is of type [object Object] is to check against the .constructor property of it:

function isObject (a) { return a != null && a.constructor === Object; }

or even shorter with arrow-functions:

const isObject = a => a != null && a.constructor === Object;

The a != null part is necessary because one might pass in null or undefined and you cannot extract a constructor property from either of these.

It works with any object created via:

• the Object constructor
• literals {}

Another neat feature of it, is it's ability to give correct reports for custom classes which make use of Symbol.toStringTag. For example:

class MimicObject {
  get [Symbol.toStringTag]() {
    return 'Object';
  }
}

The problem here is that when calling Object.prototype.toString on an instance of it, the false report [object Object] will be returned:

let fakeObj = new MimicObject();
Object.prototype.toString.call(fakeObj); // -> [object Object]

But checking against the constructor gives a correct result:

let fakeObj = new MimicObject();
fakeObj.constructor === Object; // -> false

If app is in the background mode or inactive(killed), and you click on Notification, you should check for the payload in LaunchScreen(in my case launch screen is MainActivity.java).

So in MainActivity.java on onCreate check for Extras:

    if (getIntent().getExtras() != null) {
        for (String key : getIntent().getExtras().keySet()) {
            Object value = getIntent().getExtras().get(key);
            Log.d("MainActivity: ", "Key: " + key + " Value: " + value);
        }
    }

Google recommend that you don't use any of them, source.

There is no need to use entity references like &mdash, &rdquo, or &#x263a, assuming the same encoding (UTF-8) is used for files and editors as well as among teams.

Is there a reason you can't simply use "?

I worked on this same issue and I am sure I have found out the exact reason for it.

Neither BindingResult nor plain target object for bean name 'command' available as request attribute

UPDATE

"Run as Aministrator" is just a command, enabling the program to continue some operations that require the Administrator privileges, without displaying the UAC alerts.

Even if your user is a member of administrators group, some applications like yours need the Administrator privileges to continue running, because the application is considered not safe, if it is doing some special operation, like editing a system file or something else. This is the reason why Windows needs the Administrator privilege to execute the application and it notifies you with a UAC alert. Not all applications need an Amnistrator account to run, and some applications, like yours, need the Administrator privileges.

If you execute the application with 'run as administrator' command, you are notifying the system that your application is safe and doing something that requires the administrator privileges, with your confirm.

If you want to avoid this, just disable the UAC on Control Panel.

If you want to go further, read the question Difference between "Run as Administrator" and Windows 7 Administrators Group on Microsoft forum or this SuperUser question.

This one worked for me:

In Activity:

User user;
public User getUser(){ return this.user;}

In Fragment's onCreateView method:

User user = ((MainActivity)getActivity()).getUser(); 

Replace the MainActivity with your Activity Name.

Arrays in Ruby don't have exists? method, but they have an include? method as described in the docs. Something like

unless @suggested_horses.include?(horse)
   @suggested_horses << horse
end

should work out of box.

You already have what you need, with a minor syntax change:

<a href="www.mysite.com" onclick="return theFunction();">Item</a>

<script type="text/javascript">
    function theFunction () {
        // return true or false, depending on whether you want to allow the `href` property to follow through or not
    }
</script>

The default behavior of the <a> tag's onclick and href properties is to execute the onclick, then follow the href as long as the onclick doesn't return false, canceling the event (or the event hasn't been prevented)

Ok, I deleted my previous answer because finally it was not what willlangford was looking for, but I made my point that maybe we were all misunderstanding the question.

I also thought of the SELECT DISTINCT... thing at first, but it seemed too weird to me that someone needed to know how many people had a different number of pets than the rest... thats why I thought that maybe the question was not clear enough.

So, now that the real question meaning is clarified, making a subquery for this its quite an overhead, I would preferably use a GROUP BY clause.

Imagine you have the table customer_pets like this:

+-----------------------+
|  customer  |   pets   |
+------------+----------+
| customer1  |    2     |
| customer2  |    3     |
| customer3  |    2     |
| customer4  |    2     |
| customer5  |    3     |
| customer6  |    4     |
+------------+----------+

then

SELECT count(customer) AS num_customers, pets FROM customer_pets GROUP BY pets

would return:

+----------------------------+
|  num_customers  |   pets   |
+-----------------+----------+
|        3        |    2     |
|        2        |    3     |

as you need.

You can't.

Well, of course you could, however an int (System.Int32) is not big enough to hold every possible decimal value.

That means if you cast a decimal that's larger than int.MaxValue you will overflow, and if the decimal is smaller than int.MinValue, it will underflow.

What happens when you under/overflow? One of two things. If your build is unchecked (i.e., the CLR doesn't care if you do), your application will continue after the value over/underflows, but the value in the int will not be what you expected. This can lead to intermittent bugs and may be hard to fix. You'll end up your application in an unknown state which may result in your application corrupting whatever important data its working on. Not good.

If your assembly is checked (properties->build->advanced->check for arithmetic overflow/underflow or the /checked compiler option), your code will throw an exception when an under/overflow occurs. This is probably better than not; however the default for assemblies is not to check for over/underflow.

The real question is "what are you trying to do?" Without knowing your requirements, nobody can tell you what you should do in this case, other than the obvious: DON'T DO IT.

If you specifically do NOT care, the answers here are valid. However, you should communicate your understanding that an overflow may occur and that it doesn't matter by wrapping your cast code in an unchecked block

unchecked
{
  // do your conversions that may underflow/overflow here
}

That way people coming behind you understand you don't care, and if in the future someone changes your builds to /checked, your code won't break unexpectedly.

If all you want to do is drop the fractional portion of the number, leaving the integral part, you can use Math.Truncate.

decimal actual = 10.5M;
decimal expected = 10M;
Assert.AreEqual(expected, Math.Truncate(actual));

Another option is to set the control param ClientID="Static" in .net and then you can access the object in JQuery by the ID you set.

Neither.

Django is a framework, not a language. Python is the language in which Django is written.

Django is a collection of Python libs allowing you to quickly and efficiently create a quality Web application, and is suitable for both frontend and backend.

However, Django is pretty famous for its "Django admin", an auto generated backend that allows you to manage your website in a blink for a lot of simple use cases without having to code much.

More precisely, for the front end, Django helps you with data selection, formatting, and display. It features URL management, a templating language, authentication mechanisms, cache hooks, and various navigation tools such as paginators.

For the backend, Django comes with an ORM that lets you manipulate your data source with ease, forms (an HTML independent implementation) to process user input and validate data and signals, and an implementation of the observer pattern. Plus a tons of use-case specific nifty little tools.

For the rest of the backend work Django doesn't help with, you just use regular Python. Business logic is a pretty broad term.

You probably want to know as well that Django comes with the concept of apps, a self contained pluggable Django library that solves a problem. The Django community is huge, and so there are numerous apps that do specific business logic that vanilla Django doesn't.

Remove the \s from your new regex and it should work - whitespace is already included in "anything but alphanumerics".

Note that you may want to add a + after the ] so you don't get sequences of more than one underscore. You can also chain onto .replace(/^_+|_+$/g,'') to trim off underscores at the start or end of the string.

You can use the Ildasm.exe (IL Disassembler) to examine the assembly's metadata, which contains the fully qualified name.

Do not use passwords. Use peer authentication instead:

postgres://myuser@%2Fvar%2Frun%2Fpostgresql/mydb

I am using the following test to see if strings have been urlencoded:

if(urlencode($str) != str_replace(['%','+'], ['%25','%2B'], $str))

If a string has already been urlencoded, the only characters that will changed by double encoding are % (which starts all encoded character strings) and + (which replaces spaces.) Change them back and you should have the original string.

Let me know if this works for you.
