Find some interesting defintion:

git log remotename/branchname

Will display the log of a given remote branch in that repository, but only the logs that you have "fetched" from their repository to your personal "copy" of the remote repository.

Remember that your clone of the repository will update its state of any remote branches only by doing git fetch. You can't connect directly to the server to check the log there, what you do is download the state of the server with git fetch and then locally see the log of the remote branches.

Perhaps another useful command could be:

git log HEAD..remote/branch

which will show you the commits that are in the remote branch, but not in your current branch (HEAD).

Reflection and dynamic value access are correct solutions to this question but are quite slow. If your want something faster then you can create dynamic method using expressions:

  object value = GetValue();
  string propertyName = "MyProperty";

  var parameter = Expression.Parameter(typeof(object));
  var cast = Expression.Convert(parameter, value.GetType());
  var propertyGetter = Expression.Property(cast, propertyName);
  var castResult = Expression.Convert(propertyGetter, typeof(object));//for boxing

  var propertyRetriver = Expression.Lambda<Func<object, object>>(castResult, parameter).Compile();

 var retrivedPropertyValue = propertyRetriver(value);

This way is faster if you cache created functions. For instance in dictionary where key would be the actual type of object assuming that property name is not changing or some combination of type and property name.

What SSL private key should be sent along with the client certificate?

None of them :)

One of the appealing things about client certificates is it does not do dumb things, like transmit a secret (like a password), in the plain text to a server (HTTP basic_auth). The password is still used to unlock the key for the client certificate, its just not used directly to during exchange or tp authenticate the client.

Instead, the client chooses a temporary, random key for that session. The client then signs the temporary, random key with his cert and sends it to the server (some hand waiving). If a bad guy intercepts anything, its random so it can't be used in the future. It can't even be used for a second run of the protocol with the server because the server will select a new, random value, too.

Fails with: error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure

Use TLS 1.0 and above; and use Server Name Indication.

You have not provided any code, so its not clear to me how to tell you what to do. Instead, here's the OpenSSL command line to test it:

openssl s_client -connect www.example.com:443 -tls1 -servername www.example.com \
    -cert mycert.pem -key mykey.pem -CAfile <certificate-authority-for-service>.pem

You can also use -CAfile to avoid the “verify error:num=20”. See, for example, “verify error:num=20” when connecting to gateway.sandbox.push.apple.com.

I had the same error, though the problem was that I had a typo in the url

url: 'http://api.example.com/TYPO'

The API had a redirect to another domain for all URL's that is wrong (404 errors).

So fixing the typo to the correct URL fixed it for me.

SQL Server autocreates indices for Primary Keys, but not for Foreign Keys. Create the index for the Foreign Keys. It's probably worth the overhead.

First, you have to lookup the correct ArrayList in the HashMap:

ArrayList<String> myAList = theHashMap.get(courseID)

Then, add the new grade to the ArrayList:

myAList.add(newGrade)

I would use
\b[A-Za-z]*Id\b
The \b matches the beginning and end of a word i.e. space, tab or newline, or the beginning or end of a string.

The [A-Za-z] will match any letter, and the * means that 0+ get matched. Finally there is the Id.

Note that this will match words that have capital letters in the middle such as 'teStId'.

I use http://www.regular-expressions.info/ for regex reference

If you write software, or use software written, which stores program window coordinates or sizes to be resused when starting a program, check there for any occurrence(s) of such sizes and positions which would be causing this. I've seen it time and time again from various vendors lazily producing code which resizes and repositions controls on a "form" (a program window) based on the size of said form. Look in HKLM\Software\Vendor\Program and HKCU\Software\Vendor\Program. Look for specific keys which might be offending. I once had a program store -48000 for the program window position in keys called WindowsPosX and WindowPosY. You could see the program start and running on the taskbar but since the program window itself was smaller than 48000 (the absolute value of -48000), it was positioned completely off the screen. If you're not comfortable with editing regstry information - most people aren't - then uninstall the software, use a registry cleaner to remove any leftover entries then reinstall the software and see if that doesn't fix the problem.

This will be sufficient to declare your enum variable and compare it:

enum Days {Saturday, Sunday, Tuesday, Wednesday, Thursday, Friday};
Days day = Saturday;
if (day == Saturday) {
    std::cout << "Ok its Saturday";
}

In addition to Norman Ramsey's answer, I'd like to add that you can double-quote the entire string (which may make the statement more readable and less error prone).

So if you want to search for 'foo' and replace it with the content of $BAR, you can enclose the sed command in double-quotes.

sed 's/foo/$BAR/g'
sed "s/foo/$BAR/g"

In the first, $BAR will not expand correctly while in the second $BAR will expand correctly.

Object.defineProperties(Element.prototype,{
group : {
    value: function (str, context) {
        // str is valid css selector like :not([attr_name]) or .class_name
        var t = "to_select_siblings___";
        var parent = context ? context : this.parentNode;
        parent.setAttribute(t, '');
        var rez = document.querySelectorAll("[" + t + "] " + (context ? '' : ">") + this.nodeName + (str || "")).toArray();
        parent.removeAttribute(t);            
        return rez;  
    }
},
siblings: {
    value: function (str, context) {
        var rez=this.group(str,context);
        rez.splice(rez.indexOf(this), 1);
        return rez; 
    }
},
nth: {  
    value: function(str,context){
       return this.group(str,context).indexOf(this);
    }
}
}

Ex

/* html */
<ul id="the_ul">   <li></li> ....<li><li>....<li></li>   </ul>

 /*js*/
 the_ul.addEventListener("click",
    function(ev){
       var foo=ev.target;
       foo.setAttribute("active",true);
       foo.siblings().map(function(elm){elm.removeAttribute("active")});
       alert("a click on li" + foo.nth());
     });

Solution for Swift 2:

let singleTapGesture = UITapGestureRecognizer(target: self, action: #selector(handleSingleTap))
singleTapGesture.numberOfTapsRequired = 1 // Optional for single tap
view.addGestureRecognizer(singleTapGesture)

let doubleTapGesture = UITapGestureRecognizer(target: self, action: #selector(handleDoubleTap))
doubleTapGesture.numberOfTapsRequired = 2
view.addGestureRecognizer(doubleTapGesture)

singleTapGesture.requireGestureRecognizerToFail(doubleTapGesture)

Starting with Jackson version 2.4 and above there have been some changes. Here is how you do it now:

import com.fasterxml.jackson.databind.DeserializationFeature;
import com.fasterxml.jackson.databind.ObjectMapper;

..........................................................................

 ObjectMapper mapper = new ObjectMapper();
    // to prevent exception when encountering unknown property:
 mapper.disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES);

Note: The @annotation based solution remains the same so if you like to use that see the other answers.

For more information see the 10 minutes Configuration tutorial at: https://github.com/FasterXML/jackson-databind

Albeit from the useless _T and incorrectly spelled histories. If you are using SQL*Plus, it does not accept create table statements with empty new lines between create table <name> ( and column definitions.

Since version 0.15.0 this can now be easily done using .dt to access just the date component:

df['just_date'] = df['dates'].dt.date

The above returns a datetime.date dtype, if you want to have a datetime64 then you can just normalize the time component to midnight so it sets all the values to 00:00:00:

df['normalised_date'] = df['dates'].dt.normalize()

This keeps the dtype as datetime64, but the display shows just the date value.

• pandas: .dt accessor
• pandas.Series.dt

One simple approach I have used is conditional rendering:

@(Model.ExpireDate == null ? 
  @Html.TextBoxFor(m => m.ExpireDate, new { @disabled = "disabled" }) : 
  @Html.TextBoxFor(m => m.ExpireDate)
)

Consider this implementation of foo():

public void foo(final String a) {
    SwingUtilities.invokeLater(new Runnable() {
        public void run() {
            System.out.print(a);
        }
    }); 
}

Because the Runnable instance would outlive the method, this wouldn't compile without the final keyword -- final tells the compiler that it's safe to take a copy of the reference (to refer to it later). Thus, it's the reference that's considered final, not the value. In other words: As a caller, you can't mess anything up...

1. running code before Compilation : use controller
2. running code after Compilation : use Link

Angular convention : write business logic in controller and DOM manipulation in link.

Apart from this you can call one controller function from link function of another directive.For example you have 3 custom directives

<animal>
<panther>
<leopard></leopard>
</panther> 
</animal>

and you want to access animal from inside of "leopard" directive.

http://egghead.io/lessons/angularjs-directive-communication will be helpful to know about inter-directive communication

When you #include a header, it's exactly as if you put the code into the source file itself. In both cases the varGlobal variable is defined in the source so it will work no matter how it's declared.

Also as pointed out in the comments, C++ variables at file scope are not static in scope even though they will be assigned to static storage. If the variable were a class member for example, it would need to be accessible to other compilation units in the program by default and non-class members are no different.

These are the best practices from Mozilla Developer Network's window.open page :

<script type="text/javascript">
var windowObjectReference = null; // global variable

function openFFPromotionPopup() {
  if(windowObjectReference == null || windowObjectReference.closed)
  /* if the pointer to the window object in memory does not exist
     or if such pointer exists but the window was closed */

  {
    windowObjectReference = window.open("http://www.spreadfirefox.com/",
   "PromoteFirefoxWindowName", "resizable,scrollbars,status");
    /* then create it. The new window will be created and
       will be brought on top of any other window. */
  }
  else
  {
    windowObjectReference.focus();
    /* else the window reference must exist and the window
       is not closed; therefore, we can bring it back on top of any other
       window with the focus() method. There would be no need to re-create
       the window or to reload the referenced resource. */
  };
}
</script>

<p><a

 onclick="openFFPromotionPopup(); return false;"

In Android Studio 0.8.2 , you have the same option (ie Share on GitHub). If you want to find it, you can use ctrl+shift+a and enter github in the input text.

This is an old question, but regarding the second part of the question - how can you check if the user set/didn't set a prop?

Inspecting this within the component, we have this.$options.propsData. If the prop is present here, the user has explicitly set it; default values aren't shown.

This is useful in cases where you can't really compare your value to its default, e.g. if the prop is a function.

I found git here

C:\Users\<User>\AppData\Local\GitHubDesktop\app-0.5.8\resources\app\git\cmd\git.exe

You have to write file name (git.exe) in the end of path otherwise it will give an error=5

Or you can check here also.

C:\Program Files\Git\bin\git.exe

if you want to beautify the appearance of your pagination, I use the class from bootstrap to make it more simple and easy

 @if ($students->lastPage() > 1)
        <ul class="pagination ml-auto">
            <li class="{{ ($students->currentPage() == 1) ? ' disabled' : '' }} page-item">
                <a class=" page-link " href="{{ $students->url(1) }}" aria-label="Previous">
                    <span aria-hidden="true">&laquo;</span>
                    <span class="sr-only">Previous</span>
                </a>
            </li>
            @for ($i = 1; $i <= $students->lastPage(); $i++)
                <li class="{{ ($students->currentPage() == $i) ? ' active' : '' }} page-item">
                    <a class=" page-link " href="{{ $students->url($i) }}">{{ $i }}</a>
                </li>
            @endfor
            <li class="{{ ($students->currentPage() == $students->lastPage()) ? ' disabled' : '' }} page-item">
                <a href="{{ $students->url($students->currentPage()+1) }}" class="page-link" aria-label="Next">
                    <span aria-hidden="true">&raquo;</span>
                    <span class="sr-only">Next</span>
                </a>
            </li>
        </ul>
@endif

The recommended way will be to build this into the thread. So no you can't (or rather shouldn't) kill the thread from outside.

Have the thread check infrequently if it is required to stop. (Instead of blocking on a socket until there is data. Use a timeout and every once in a while check if the user indicated wanting to stop)

Yes, all these are possible when you have the direct access to the servers. But what if you have only access to the server from a web / application server? Well, the situation was this with us a long back and the solution was SQL Server Export to CSV.

Just put your data into an Object like this:

var myObject = new Object();
myObject.name = "John";
myObject.age = 12;
myObject.pets = ["cat", "dog"];

Afterwards stringify it via:

var myString = JSON.stringify(myObject);

You don't need jQuery for this. It's pure JS.

From Android O, you cant use the services for the long running background operations due to this, https://developer.android.com/about/versions/oreo/background . Jobservice will be the better option with Jobscheduler implementation.

Wikipedia has this to say:

Additionally, such icon files can be either 16×16 or 32×32 pixels in size, and either 8-bit or 24-bit in color depth (note that GIF files have a limited, 256 color palette entries).

I think the best way is to use a 32x32 gif and test it with different browsers.

I had similar problem recently in two column grid, I needed a margin on elements in right column only. All elements in both columns were of type TextBlock.

<Grid.Resources>
    <Style TargetType="{x:Type TextBlock}" BasedOn="{StaticResource OurLabelStyle}">
        <Style.Triggers>
            <Trigger Property="Grid.Column" Value="1">
                <Setter Property="Margin" Value="20,0" />
            </Trigger>
        </Style.Triggers>
    </Style>
</Grid.Resources>

Firstly, as Etienne says, float in C# is Single. It is just the C# keyword for that data type.

So you can definitely do this:

float f = 13.5f;
string s = f.ToString("R");

Secondly, you have referred a couple of times to the number's "format"; numbers don't have formats, they only have values. Strings have formats. Which makes me wonder: what is this thing you have that has a format but is not a string? The closest thing I can think of would be decimal, which does maintain its own precision; however, calling simply decimal.ToString should have the effect you want in that case.

How about including some example code so we can see exactly what you're doing, and why it isn't achieving what you want?

I believe what you are looking for is "git restore".

The easiest way is to remove the file locally, and then execute the git restore command for that file:

$ rm file.txt
$ git restore file.txt 

You can check if the Connected property is set to $true and display a friendly message:

    $t = New-Object Net.Sockets.TcpClient "10.45.23.109", 443 

    if($t.Connected)
    {
        "Port 443 is operational"
    }
    else
    {
        "..."
    }

How about adding this to your pom.xml

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-annotations</artifactId>
    <version>${jackson.version}</version>
</dependency>

Mockito [3.4.0] can mock static methods!

1. Replace mockito-core dependency with mockito-inline:3.4.0.

2. Class with static method:

   class Buddy {
     static String name() {
       return "John";
     }
   }
   

3. Use new method Mockito.mockStatic():

   @Test
   void lookMomICanMockStaticMethods() {
     assertThat(Buddy.name()).isEqualTo("John");
   
     try (MockedStatic<Buddy> theMock = Mockito.mockStatic(Buddy.class)) {
       theMock.when(Buddy::name).thenReturn("Rafael");
       assertThat(Buddy.name()).isEqualTo("Rafael");
     }
   
     assertThat(Buddy.name()).isEqualTo("John");
   }
   

   Mockito replaces the static method within the try block only.

You can't with an enum. Maybe an enum isn't the best fit for your situation.

A common convention is to name the last enum value something like MAX and use that to control a loop using an int.

Well you can try this.

  <object data="URL_TO_Default_img.png" type="image/png">
   <img src="your_original_image.png" />
  </object>

this worked for me. let me know about you.

It seems like you are looking for the Character.forDigit method:

final int RADIX = 10;
int i = 4;
char ch = Character.forDigit(i, RADIX);
System.out.println(ch); // Prints '4'

There is also a method that can convert from a char back to an int:

int i2 = Character.digit(ch, RADIX);
System.out.println(i2); // Prints '4'

Note that by changing the RADIX you can also support hexadecimal (radix 16) and any radix up to 36 (or Character.MAX_RADIX as it is also known as).

I'm way late, but check out Quandl. They have an API for stock prices and fundamentals.

Here's an example call, using Quandl-api download in csv

example:

https://www.quandl.com/api/v1/datasets/WIKI/AAPL.csv?column=4&sort_order=asc&collapse=quarterly&trim_start=2012-01-01&trim_end=2013-12-31

They support these languages. Their source data comes from Yahoo Finance, Google Finance, NSE, BSE, FSE, HKEX, LSE, SSE, TSE and more (see here).

For Swift use this...

UIGraphicsBeginImageContext(self.view.frame.size)
UIImage(named: "ImageName.png")?.draw(in: self.view.bounds)

if let image = UIGraphicsGetImageFromCurrentImageContext(){
    UIGraphicsEndImageContext()
    self.view.backgroundColor = UIColor(patternImage: image)
}else{
    UIGraphicsEndImageContext()
    debugPrint("Image not available")
 }

It's unbelievable how much misleading information you can read in articles above...

And even in microsoft msdn documentation IsBadPtr is claimed to be banned. Oh well - I prefer working application rather than crashing. Even if term working might be working incorrectly (as long as end-user can continue with application).

By googling I haven't found any useful example for windows - found a solution for 32-bit apps,

http://www.codeproject.com/script/Content/ViewAssociatedFile.aspx?rzp=%2FKB%2Fsystem%2Fdetect-driver%2F%2FDetectDriverSrc.zip&zep=DetectDriverSrc%2FDetectDriver%2Fsrc%2FdrvCppLib%2Frtti.cpp&obid=58895&obtid=2&ovid=2

but I need also to support 64-bit apps, so this solution did not work for me.

But I've harvested wine's source codes, and managed to cook similar kind of code which would work for 64-bit apps as well - attaching code here:

#include <typeinfo.h>   

typedef void (*v_table_ptr)();   

typedef struct _cpp_object   
{   
    v_table_ptr*    vtable;   
} cpp_object;   



#ifndef _WIN64
typedef struct _rtti_object_locator
{
    unsigned int signature;
    int base_class_offset;
    unsigned int flags;
    const type_info *type_descriptor;
    //const rtti_object_hierarchy *type_hierarchy;
} rtti_object_locator;
#else

typedef struct
{
    unsigned int signature;
    int base_class_offset;
    unsigned int flags;
    unsigned int type_descriptor;
    unsigned int type_hierarchy;
    unsigned int object_locator;
} rtti_object_locator;  

#endif

/* Get type info from an object (internal) */  
static const rtti_object_locator* RTTI_GetObjectLocator(void* inptr)  
{   
    cpp_object* cppobj = (cpp_object*) inptr;  
    const rtti_object_locator* obj_locator = 0;   

    if (!IsBadReadPtr(cppobj, sizeof(void*)) &&   
        !IsBadReadPtr(cppobj->vtable - 1, sizeof(void*)) &&   
        !IsBadReadPtr((void*)cppobj->vtable[-1], sizeof(rtti_object_locator)))  
    {  
        obj_locator = (rtti_object_locator*) cppobj->vtable[-1];  
    }  

    return obj_locator;  
}  

And following code can detect whether pointer is valid or not, you need probably to add some NULL checking:

    CTest* t = new CTest();
    //t = (CTest*) 0;
    //t = (CTest*) 0x12345678;

    const rtti_object_locator* ptr = RTTI_GetObjectLocator(t);  

#ifdef _WIN64
    char *base = ptr->signature == 0 ? (char*)RtlPcToFileHeader((void*)ptr, (void**)&base) : (char*)ptr - ptr->object_locator;
    const type_info *td = (const type_info*)(base + ptr->type_descriptor);
#else
    const type_info *td = ptr->type_descriptor;
#endif
    const char* n =td->name();

This gets class name from pointer - I think it should be enough for your needs.

One thing which I'm still afraid is performance of pointer checking - in code snipet above there is already 3-4 API calls being made - might be overkill for time critical applications.

It would be good if someone could measure overhead of pointer checking compared for example to C#/managed c++ calls.

dplyr now has a function case_when that offers a vectorised if. The syntax is a little strange compared to mosaic:::derivedFactor as you cannot access variables in the standard dplyr way, and need to declare the mode of NA, but it is considerably faster than mosaic:::derivedFactor.

df %>%
mutate(g = case_when(a %in% c(2,5,7) | (a==1 & b==4) ~ 2L, 
                     a %in% c(0,1,3,4) | c == 4 ~ 3L, 
                     TRUE~as.integer(NA)))

EDIT: If you're using dplyr::case_when() from before version 0.7.0 of the package, then you need to precede variable names with '.$' (e.g. write .$a == 1 inside case_when).

Benchmark: For the benchmark (reusing functions from Arun 's post) and reducing sample size:

require(data.table) 
require(mosaic) 
require(dplyr)
require(microbenchmark)

set.seed(42) # To recreate the dataframe
DT <- setDT(lapply(1:6, function(x) sample(7, 10000, TRUE)))
setnames(DT, letters[1:6])
DF <- as.data.frame(DT)

DPLYR_case_when <- function(DF) {
  DF %>%
  mutate(g = case_when(a %in% c(2,5,7) | (a==1 & b==4) ~ 2L, 
                       a %in% c(0,1,3,4) | c==4 ~ 3L, 
                       TRUE~as.integer(NA)))
}

To append key-value pairs to a json string, you can use dict.update: dictA.update(dictB).

For your case, this will look like this:

dictA = json.loads(jsonStringA)
dictB = json.loads('{"error_1395952167":"Error Occured on machine h1 in datacenter dc3 on the step2 of process test"}')

dictA.update(dictB)
jsonStringA = json.dumps(dictA)

Note that key collisions will cause values in dictB overriding dictA.

Android actually has a built-in InputFilter just for this!

edittext.setFilters(new InputFilter[] {new InputFilter.AllCaps()});

Be careful, setFilters will reset all other attributes which were set via XML (i.e. maxLines, inputType,imeOptinos...). To prevent this, add you Filter(s) to the already existing ones.

InputFilter[] editFilters = <EditText>.getFilters();
InputFilter[] newFilters = new InputFilter[editFilters.length + 1];
System.arraycopy(editFilters, 0, newFilters, 0, editFilters.length);
newFilters[editFilters.length] = <YOUR_FILTER>;  
<EditText>.setFilters(newFilters);

select database on the left side. Then on the right-central top you can find Operations. In that go for remove database (DROP). That's all.

Right now i am developing using System.Data.SQlite NuGet package (version 1.0.109.2). Which using SQLite version 3.24.0.

And this works for me.

SELECT * FROM tables WHERE datetime 
BETWEEN '2018-10-01 00:00:00' AND '2018-10-10 23:59:59';

I don't net to use the datetime() function. Perhaps they already updated the SQL query on that SQLite version.

Treat function as variable in your program so you can just pass them to other functions easily:

def test ():
   print "test was invoked"

def invoker(func):
   func()

invoker(test)  # prints test was invoked

I had this problem when installing Heroku Toolbelt

This is how I solved the problem

$ ls -l /bin/sh
lrwxrwxrwx 1 root root 4 ago 15  2012 /bin/sh -> dash

As you can see, /bin/sh is a link to "dash" (not bash), and [[ is bash syntactic sugarness. So I just replaced the link to /bin/bash. Careful using rm like this in your system!

$ sudo rm /bin/sh
$ sudo ln -s /bin/bash /bin/sh

Update numpy.

pip install numpy --upgrade

Work for me!!

Here is a solution that will work with list or dict type arguments without whining:

def memoize(fn):
    """returns a memoized version of any function that can be called
    with the same list of arguments.
    Usage: foo = memoize(foo)"""

    def handle_item(x):
        if isinstance(x, dict):
            return make_tuple(sorted(x.items()))
        elif hasattr(x, '__iter__'):
            return make_tuple(x)
        else:
            return x

    def make_tuple(L):
        return tuple(handle_item(x) for x in L)

    def foo(*args, **kwargs):
        items_cache = make_tuple(sorted(kwargs.items()))
        args_cache = make_tuple(args)
        if (args_cache, items_cache) not in foo.past_calls:
            foo.past_calls[(args_cache, items_cache)] = fn(*args,**kwargs)
        return foo.past_calls[(args_cache, items_cache)]
    foo.past_calls = {}
    foo.__name__ = 'memoized_' + fn.__name__
    return foo

Note that this approach can be naturally extended to any object by implementing your own hash function as a special case in handle_item. For example, to make this approach work for a function that takes a set as an input argument, you could add to handle_item:

if is_instance(x, set):
    return make_tuple(sorted(list(x)))

Minor variation of phillfri's answer which was already a variation of Geoff's answer: I added the ability to handle completely empty tables that contain no data for the Array Code.

Sub AddDataRow(tableName As String, NewData As Variant)
    Dim sheet As Worksheet
    Dim table As ListObject
    Dim col As Integer
    Dim lastRow As Range

    Set sheet = Range(tableName).Parent
    Set table = sheet.ListObjects.Item(tableName)

    'First check if the last row is empty; if not, add a row
    If table.ListRows.Count > 0 Then
        Set lastRow = table.ListRows(table.ListRows.Count).Range
        If Application.CountBlank(lastRow) < lastRow.Columns.Count Then
            table.ListRows.Add
        End If
    End If

    'Iterate through the last row and populate it with the entries from values()
    If table.ListRows.Count = 0 Then 'If table is totally empty, set lastRow as first entry
        table.ListRows.Add Position:=1
        Set lastRow = table.ListRows(1).Range
    Else
        Set lastRow = table.ListRows(table.ListRows.Count).Range
    End If
    For col = 1 To lastRow.Columns.Count
        If col <= UBound(NewData) + 1 Then lastRow.Cells(1, col) = NewData(col - 1)
    Next col
End Sub

Depending on which OS you're using, if you are flexible, then CHOICE can be used to wait on almost any key EXCEPT enter

If you are really referring to what Microsoft insists on calling "Command Prompt" which is simply an MS-DOS emulator, then perhaps TIMEOUT may suit your purpose (timeout /t -1 waits on any key, not just ENTER) and of course CHOICE is available again in recent WIN editions.

And a warning on SET /P - whereas set /p DUMMY=Hit ENTER to continue... will work,

set "dummy="
set /p DUMMY=Hit ENTER to continue...
if defined dummy (echo not just ENTER was pressed) else (echo just ENTER was pressed)

will detect whether just ENTER or something else, ending in ENTER was keyed in.

Not a regexp expert, but I think you could use a negative lookahead from the start, e.g. ^(?!foo).*$ shouldn't match anything starting with foo.

If I move CreateUser.py to the main user_management directory, I can easily use: import Modules.LDAPManager to import LDAPManager.py --- this works.

Please, don't. In this way the LDAPManager module used by CreateUser will not be the same as the one imported via other imports. This can create problems when you have some global state in the module or during pickling/unpickling. Avoid imports that work only because the module happens to be in the same directory.

When you have a package structure you should either:

• Use relative imports, i.e if the CreateUser.py is in Scripts/:

   from ..Modules import LDAPManager
  

  Note that this was (note the past tense) discouraged by PEP 8 only because old versions of python didn't support them very well, but this problem was solved years ago. The current version of PEP 8 does suggest them as an acceptable alternative to absolute imports. I actually like them inside packages.

• Use absolute imports using the whole package name(CreateUser.py in Scripts/):

   from user_management.Modules import LDAPManager
  

In order for the second one to work the package user_management should be installed inside the PYTHONPATH. During development you can configure the IDE so that this happens, without having to manually add calls to sys.path.append anywhere.

Also I find it odd that Scripts/ is a subpackage. Because in a real installation the user_management module would be installed under the site-packages found in the lib/ directory (whichever directory is used to install libraries in your OS), while the scripts should be installed under a bin/ directory (whichever contains executables for your OS).

In fact I believe Script/ shouldn't even be under user_management. It should be at the same level of user_management. In this way you do not have to use -m, but you simply have to make sure the package can be found (this again is a matter of configuring the IDE, installing the package correctly or using PYTHONPATH=. python Scripts/CreateUser.py to launch the scripts with the correct path).

In summary, the hierarchy I would use is:

user_management  (package)
        |
        |------- __init__.py
        |
        |------- Modules/
        |           |
        |           |----- __init__.py
        |           |----- LDAPManager.py
        |           |----- PasswordManager.py
        |

 Scripts/  (*not* a package)
        |  
        |----- CreateUser.py
        |----- FindUser.py

Then the code of CreateUser.py and FindUser.py should use absolute imports to import the modules:

from user_management.Modules import LDAPManager

During installation you make sure that user_management ends up somewhere in the PYTHONPATH, and the scripts inside the directory for executables so that they are able to find the modules. During development you either rely on IDE configuration, or you launch CreateUser.py adding the Scripts/ parent directory to the PYTHONPATH (I mean the directory that contains both user_management and Scripts):

PYTHONPATH=/the/parent/directory python Scripts/CreateUser.py

Or you can modify the PYTHONPATH globally so that you don't have to specify this each time. On unix OSes (linux, Mac OS X etc.) you can modify one of the shell scripts to define the PYTHONPATH external variable, on Windows you have to change the environmental variables settings.

Addendum I believe, if you are using python2, it's better to make sure to avoid implicit relative imports by putting:

from __future__ import absolute_import

at the top of your modules. In this way import X always means to import the toplevel module X and will never try to import the X.py file that's in the same directory (if that directory isn't in the PYTHONPATH). In this way the only way to do a relative import is to use the explicit syntax (the from . import X), which is better (explicit is better than implicit).

This will make sure you never happen to use the "bogus" implicit relative imports, since these would raise an ImportError clearly signalling that something is wrong. Otherwise you could use a module that's not what you think it is.

drop constraint and recreate it

alter table Persion drop CONSTRAINT <constraint_name>

alter table Persion add primary key (persionId,Pname,PMID)

edit:

you can find the constraint name by using the query below:

select OBJECT_NAME(OBJECT_ID) AS NameofConstraint
FROM sys.objects
where OBJECT_NAME(parent_object_id)='Persion'
and type_desc LIKE '%CONSTRAINT'

What if your server goes down at 4:59AM and comes back at 5:01AM? I think it will just skip the run. I would recommend persistent scheduler like Quartz, that would store its schedule data somewhere. Then it will see that this run hasn't been performed yet and will do it at 5:01AM.

Replace the username and password with Integrated Security=SSPI;

So the connection string should be

<connectionStrings> 
<add name="NorthwindContex" 
   connectionString="data source=localhost;
   initial catalog=northwind;persist security info=True; 
   Integrated Security=SSPI;" 
   providerName="System.Data.SqlClient" /> 
</connectionStrings> 

You can also bind to contextmenu and return false:

$('selector').bind('contextmenu', function(e){
    e.preventDefault();
    //code
    return false;
});

Demo: http://jsfiddle.net/maniator/WS9S2/

Or you can make a quick plugin that does the same:

(function( $ ) {
  $.fn.rightClick = function(method) {

    $(this).bind('contextmenu rightclick', function(e){
        e.preventDefault();
        method();
        return false;
    });

  };
})( jQuery );

Demo: http://jsfiddle.net/maniator/WS9S2/2/

Using .on(...) jQuery >= 1.7:

$(document).on("contextmenu", "selector", function(e){
    e.preventDefault();
    //code
    return false;
});  //does not have to use `document`, it could be any container element.

Demo: http://jsfiddle.net/maniator/WS9S2/283/

Strictly speaking, you should put something that makes sense - according to the spec here, the most correct version is:

<input name=name id=id type=checkbox checked=checked>

For HTML, you can also use the empty attribute syntax, checked="", or even simply checked (for stricter XHTML, this is not supported).

Effectively, however, most browsers will support just about any value between the quotes. All of the following will be checked:

<input name=name id=id type=checkbox checked>
<input name=name id=id type=checkbox checked="">
<input name=name id=id type=checkbox checked="yes">
<input name=name id=id type=checkbox checked="blue">
<input name=name id=id type=checkbox checked="false">

And only the following will be unchecked:

<input name=name id=id type=checkbox>

See also this similar question on disabled="disabled".

You can send it as raw xml

Unfortunately, we do not have a "TRUNCATE TABLE" command in SQLite, but you can use SQLite's DELETE command to delete the complete data from an existing table, though it is recommended to use the DROP TABLE command to drop the complete table and re-create it once again.

I am using this on PHP 7.2.x, it's working fine for me:

public function make_hash($userStr){
        try{
            /** 
             * Used and tested on PHP 7.2x, Salt has been removed manually, it is now added by PHP 
             */
             return password_hash($userStr, PASSWORD_BCRYPT);
            }catch(Exception $exc){
                $this->tempVar = $exc->getMessage();
                return false;
            }
        }

and then authenticate the hash with the following function:

public function varify_user($userStr,$hash){
        try{
            if (password_verify($userStr, $hash)) {
                 return true;
                }
            else {
                return false;
                }
            }catch(Exception $exc){
                $this->tempVar = $exc->getMessage();
                return false;
            }
        }

Example:

  //create hash from user string

 $user_password = $obj->make_hash2($user_key);

and to authenticate this hash use the following code:

if($obj->varify_user($key, $user_key)){
      //this is correct, you can proceed with  
    }

That's all.

Checkout this wiki, specifically the section Restrictions on valid host names

Hostnames are composed of series of labels concatenated with dots, as are all domain names. For example, "en.wikipedia.org" is a hostname. Each label must be between 1 and 63 characters long, and the entire hostname (including the delimiting dots but not a trailing dot) has a maximum of 253 ASCII characters.

The Internet standards (Requests for Comments) for protocols mandate that component hostname labels may contain only the ASCII letters 'a' through 'z' (in a case-insensitive manner), the digits '0' through '9', and the hyphen ('-'). The original specification of hostnames in RFC 952, mandated that labels could not start with a digit or with a hyphen, and must not end with a hyphen. However, a subsequent specification (RFC 1123) permitted hostname labels to start with digits. No other symbols, punctuation characters, or white space are permitted.

You can use a MinMaxPriorityQueue from Google Guava, from the javadoc:

A min-max priority queue can be configured with a maximum size. If so, each time the size of the queue exceeds that value, the queue automatically removes its greatest element according to its comparator (which might be the element that was just added). This is different from conventional bounded queues, which either block or reject new elements when full.

I got stuck during Android SDK Setup (API Level 19 and 21) Turning OFF and ON the Internet connection resolved the issue and the installation completed successfully.

The text uses combining characters, also known as combining marks. See section 2.11 of Combining Characters in the Unicode Standard (PDF).

In Unicode, character rendering does not use a simple character cell model where each glyph fits into a box with given height. Combining marks may be rendered above, below, or inside a base character

So you can easily construct a character sequence, consisting of a base character and “combining above” marks, of any length, to reach any desired visual height, assuming that the rendering software conforms to the Unicode rendering model. Such a sequence has no meaning of course, and even a monkey could produce it (e.g., given a keyboard with suitable driver).

And you can mix “combining above” and “combining below” marks.

The sample text in the question starts with:

• LATIN CAPITAL LETTER H - H
• COMBINING LATIN SMALL LETTER T - ͭ
• COMBINING GREEK KORONIS - ̓
• COMBINING COMMA ABOVE - ̓
• COMBINING DOT ABOVE - ̇

Visibility:

While your angularjs is bootstrapping, the user might see your placed brackets in the html. This can be handled with ng-cloak. But for me this is a workaround, that I don't need to use, if I use ng-bind.

Performance:

The {{}} is much slower.

This ng-bind is a directive and will place a watcher on the passed variable. So the ng-bind will only apply, when the passed value does actually change.

The brackets on the other hand will be dirty checked and refreshed in every $digest, even if it's not necessary.

I am currently building a big single page app (~500 bindings per view). Changing from {{}} to strict ng-bind did save us about 20% in every scope.$digest.

Suggestion:

If you use a translation module such as angular-translate, always prefer directives before brackets annotation.

{{'WELCOME'|translate}} => <span ng-translate="WELCOME"></span>

If you need a filter function, better go for a directive, that actually just uses your custom filter. Documentation for $filter service

UPDATE 28.11.2014 (but maybe off the topic):

In Angular 1.3x the bindonce functionality was introduced. Therefore you can bind the value of an expression/attribute once (will be bound when != 'undefined').

This is useful when you don't expect your binding to change.

Usage: Place :: before your binding:

<ul>  
  <li ng-repeat="item in ::items">{{item}}</li>
</ul>  
<a-directive name="::item">
<span data-ng-bind="::value"></span>

Example:

ng-repeat to output some data in the table, with multiple bindings per row. Translation-bindings, filter outputs, which get executed in every scope digest.

In my case it happened for leaving some empty intent-filter inside the Activity tag

    <activity
            android:name=".MainActivity"
            android:label="@string/app_name"
            android:theme="@style/AppTheme.NoActionBar">

            <intent-filter>

            </intent-filter>

    </activity> 

So just removing them solved the problem.

    <activity
            android:name=".MainActivity"
            android:label="@string/app_name"
            android:theme="@style/AppTheme.NoActionBar">
    </activity> 

Updated Version (Version 5.0 & Later):

use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;

class Post extends Model {

    use SoftDeletes;

    protected $table = 'posts';

    // ...
}

When soft deleting a model, it is not actually removed from your database. Instead, a deleted_at timestamp is set on the record. To enable soft deletes for a model, specify the softDelete property on the model (Documentation).

For (Version 4.2):

use Illuminate\Database\Eloquent\SoftDeletingTrait; // <-- This is required

class Post extends Eloquent {

    use SoftDeletingTrait;

    protected $table = 'posts';

    // ...
}

Prior to Version 4.2 (But not 4.2 & Later)

For example (Using a posts table and Post model):

class Post extends Eloquent {

    protected $table = 'posts';
    protected $softDelete = true;
    
    // ...
}

To add a deleted_at column to your table, you may use the softDeletes method from a migration:

For example (Migration class' up method for posts table) :

/**
 * Run the migrations.
 *
 * @return void
 */
public function up()
{
    Schema::create('posts', function(Blueprint $table)
    {
        $table->increments('id');
        // more fields
        $table->softDeletes(); // <-- This will add a deleted_at field
        $table->timeStamps();
    });
}

Now, when you call the delete method on the model, the deleted_at column will be set to the current timestamp. When querying a model that uses soft deletes, the "deleted" models will not be included in query results. To soft delete a model you may use:

$model = Contents::find( $id );
$model->delete();

Deleted (soft) models are identified by the timestamp and if deleted_at field is NULL then it's not deleted and using the restore method actually makes the deleted_at field NULL. To permanently delete a model you may use forceDelete method.

You have to initialise the object (create the object itself) in order to be able to call its methods otherwise you would get a NullPointerException.

Four years later: another way, avoiding replace

I know the accepted answer from four years ago works, but this seems a tad lighter than using replace:

dt = datetime.date.today()
dt = datetime.datetime(dt.year, dt.month, dt.day)

Notes

• When you create a datetime object without passing time properties to the constructor, you get midnight.
• As others have noted, this assumes you want a datetime object for later use with timedeltas.
• You can, of course, substitute this for the first line: dt = datetime.datetime.now()

You can move your function definitions into a separate file and then load them into your script using the . command, like this:

. /path/to/functions.sh

This will interpret functions.sh as if it's content were actually present in your file at this point. This is a common mechanism for implementing shared libraries of shell functions.

I arrived to this question looking for the same but for Chromium (actually I'm using https://ungoogled-software.github.io). So in case anyone else is looking for the same:

1. Go to chrome://flags/
2. Search for Handling of extension MIME type requests
3. Select Always prompt for install
4. Search for an extension and copy its URL (something like https://chrome.google.com/webstore/detail/...)
5. Paste the URL in https://crxextractor.com/ and download the .CRX
6. Voilà, Chromium will prompt for installation

You should initialize yours recordings. You are passing to adapter null

ArrayList<String> recordings = null; //You are passing this null

Use the static methods in the Math class for both - there are no operators for this in the language:

double root = Math.sqrt(value);
double absolute = Math.abs(value);

(Likewise there's no operator for raising a value to a particular power - use Math.pow for that.)

If you use these a lot, you might want to use static imports to make your code more readable:

import static java.lang.Math.sqrt;
import static java.lang.Math.abs;

...

double x = sqrt(abs(x) + abs(y));

instead of

double x = Math.sqrt(Math.abs(x) + Math.abs(y));

I was facing this issue and then later realized that I was missing the @Configuration annotation in the MvcConfig class which basically does the mapping for ViewControllers and setViewNames.

Here is the content of the file :

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
**@Configuration**
public class MvcConfig implements WebMvcConfigurer{
   public void addViewControllers(ViewControllerRegistry registry)
   {
      registry.addViewController("/").setViewName("login");
      registry.addViewController("/login").setViewName("login");
      registry.addViewController("/dashboard").setViewName("dashboard");
   }
}

Hope this helps somebody!!

Use Convert.ToDouble(value) rather than (double)value. It takes an object and supports all of the types you asked for! :)

Also, your method is always returning a string in the code above; I'd recommend having the method indicate so, and give it a more obvious name (public string FormatLargeNumber(object value))

Or by using DBIs sqlRownamesToColumn

library(DBI)
sqlRownamesToColumn(df)

Even though the <head> and <body> tags aren't required, the elements are still there - it's just that the browser can work out where the tags would have been from the rest of the document.

The other elements you're using still have to be inside the <body>

Previous answers were good and correct, but in my opinion, an extra names parameter will make it perfect, and it should be the recommended way, especially when the csv has no headers.

Solution

Use usecols and names parameters

df = pd.read_csv(file_path, usecols=[3,6], names=['colA', 'colB'])

Additional reading

or use header=None to explicitly tells people that the csv has no headers (anyway both lines are identical)

df = pd.read_csv(file_path, usecols=[3,6], names=['colA', 'colB'], header=None)

So that you can retrieve your data by

# with `names` parameter
df['colA']
df['colB'] 

instead of

# without `names` parameter
df[0]
df[1]

Explain

Based on read_csv, when names are passed explicitly, then header will be behaving like None instead of 0, so one can skip header=None when names exist.

You can roughly think of any and all as series of logical or and and operators, respectively.

any

any will return True when at least one of the elements is Truthy. Read about Truth Value Testing.

all

all will return True only when all the elements are Truthy.

Truth table

+-----------------------------------------+---------+---------+
|                                         |   any   |   all   |
+-----------------------------------------+---------+---------+
| All Truthy values                       |  True   |  True   |
+-----------------------------------------+---------+---------+
| All Falsy values                        |  False  |  False  |
+-----------------------------------------+---------+---------+
| One Truthy value (all others are Falsy) |  True   |  False  |
+-----------------------------------------+---------+---------+
| One Falsy value (all others are Truthy) |  True   |  False  |
+-----------------------------------------+---------+---------+
| Empty Iterable                          |  False  |  True   |
+-----------------------------------------+---------+---------+

Note 1: The empty iterable case is explained in the official documentation, like this

any

Return True if any element of the iterable is true. If the iterable is empty, return False

Since none of the elements are true, it returns False in this case.

all

Return True if all elements of the iterable are true (or if the iterable is empty).

Since none of the elements are false, it returns True in this case.

Note 2:

Another important thing to know about any and all is, it will short-circuit the execution, the moment they know the result. The advantage is, entire iterable need not be consumed. For example,

>>> multiples_of_6 = (not (i % 6) for i in range(1, 10))
>>> any(multiples_of_6)
True
>>> list(multiples_of_6)
[False, False, False]

Here, (not (i % 6) for i in range(1, 10)) is a generator expression which returns True if the current number within 1 and 9 is a multiple of 6. any iterates the multiples_of_6 and when it meets 6, it finds a Truthy value, so it immediately returns True, and rest of the multiples_of_6 is not iterated. That is what we see when we print list(multiples_of_6), the result of 7, 8 and 9.

This excellent thing is used very cleverly in this answer.

With this basic understanding, if we look at your code, you do

any(x) and not all(x)

which makes sure that, atleast one of the values is Truthy but not all of them. That is why it is returning [False, False, False]. If you really wanted to check if both the numbers are not the same,

print [x[0] != x[1] for x in zip(*d['Drd2'])]

With Apache Commons Lang3 lib is it very easy.

import org.apache.commons.lang3.StringUtils;
import org.apache.commons.lang3.text.WordUtils;

public String getName(String text) {
  return StringUtils.remove(WordUtils.capitalizeFully(text, '_'), "_");
}

Example:

getName("SOME_CONSTANT");

Gives:

"SomeConstant"

I found my solution here. Basically use an app called Proximity Screen Off Lite and set it as below:

1. Screen On/Off Modes Check "Cover and hold to turn on Screen" Timeout: 1 second Check "Disable Accidentla Lock" Timeout: 4 seconds

2. All settings Check "Disable in Lanscape" Check "Lock phone on screen ON"

3. [Advanced] Configure Sensore Select sensor: Proximity sensor Value when sensor covered: 0 Value when sensor un-covered: 1

Try deleting your ASO files.

ASO files are cached compiled versions of your class files. Although the IDE is a lot better at letting go of old caches when changes are made, sometimes you have to manually delete them. To delete ASO files: Control>Delete ASO Files.

This is also the cause of the "I-am-not-seeing-my-changes-so-let-me-add-a-trace-now-everything-works" bug that was introduced in CS3.

Original answer:

I too tried to change the support library to "23". When I changed the targetSdkVersion to 23, Android Studio reported the following error:

This support library should not use a lower version (22) than the targetSdkVersion (23)

I simply changed:

compile 'com.android.support:appcompat-v7:23.0.0'

to

compile 'com.android.support:appcompat-v7:+'

Although this fixed my issue, you should not use dynamic versions. After a few hours the new support repository was available and it is currently 23.0.1.

Pro tip:

You can use double quotes and create a ${supportLibVersion} variable for simplicity. Example:

ext {
    supportLibVersion = '23.1.1'
}

compile "com.android.support:appcompat-v7:${supportLibVersion}"
compile "com.android.support:design:${supportLibVersion}"
compile "com.android.support:palette-v7:${supportLibVersion}"
compile "com.android.support:customtabs:${supportLibVersion}"
compile "com.android.support:gridlayout-v7:${supportLibVersion}"

length and dbms_lob.getlength return the number of characters when applied to a CLOB (Character LOB). When applied to a BLOB (Binary LOB), dbms_lob.getlength will return the number of bytes, which may differ from the number of characters in a multi-byte character set.

As the documentation doesn't specify what happens when you apply length on a BLOB, I would advise against using it in that case. If you want the number of bytes in a BLOB, use dbms_lob.getlength.

find [SOURCEPATH] -type f -name '[PATTERN]' | 
    while read P; do cp --parents "$P" [DEST]; done

you may remove the --parents but there is a risk of collision if multiple files bear the same name.

For 'Hello' at the start of the string:

SELECT STUFF('Hello World', 1, 6, '')

This will work for 'Hello' anywhere in the string:

SELECT REPLACE('Hello World', 'Hello ', '')

You could do what React warns you when you try to set the "selected" property of the <option>:

Use the defaultValue or value props on <select> instead of setting selected on <option>.

So, you can use options.value on the defaultValue of your select

I was just wondering how the random number generator in C# works.

That's implementation-specific, but the wikipedia entry for pseudo-random number generators should give you some ideas.

I was also curious how I could make a program that generates random WHOLE INTEGER numbers from 1-100.

You can use Random.Next(int, int):

Random rng = new Random();
for (int i = 0; i < 10; i++)
{
    Console.WriteLine(rng.Next(1, 101));
}

Note that the upper bound is exclusive - which is why I've used 101 here.

You should also be aware of some of the "gotchas" associated with Random - in particular, you should not create a new instance every time you want to generate a random number, as otherwise if you generate lots of random numbers in a short space of time, you'll see a lot of repeats. See my article on this topic for more details.

HashSet<String> (or) any Set implementation may does the job for you. Set don't allow duplicates.

Here is javadoc for HashSet.

if you don't want to use any 3rd party library or any random solution then just use google lib for detecting it.

This is the Simple method, Use ParseExact

CultureInfo provider = CultureInfo.InvariantCulture;
DateTime result;
String dateString = "Sun 08 Jun 2013 8:30 AM -06:00";

This should work for you.

It's done by binding to the scroll event of the container (usually window).

Quick example:

// Cache selectors
var topMenu = $("#top-menu"),
    topMenuHeight = topMenu.outerHeight()+15,
    // All list items
    menuItems = topMenu.find("a"),
    // Anchors corresponding to menu items
    scrollItems = menuItems.map(function(){
      var item = $($(this).attr("href"));
      if (item.length) { return item; }
    });

// Bind to scroll
$(window).scroll(function(){
   // Get container scroll position
   var fromTop = $(this).scrollTop()+topMenuHeight;

   // Get id of current scroll item
   var cur = scrollItems.map(function(){
     if ($(this).offset().top < fromTop)
       return this;
   });
   // Get the id of the current element
   cur = cur[cur.length-1];
   var id = cur && cur.length ? cur[0].id : "";
   // Set/remove active class
   menuItems
     .parent().removeClass("active")
     .end().filter("[href='#"+id+"']").parent().addClass("active");
});?

See the above in action at jsFiddle including scroll animation.

As an alternative to the answers you already have, and for others that come accross this post. I recently had a similar task and created a small jquery plug in to do it for me. Its pretty small under 3KB minified, and has sorting, paging and the ability to show and hide columns.

It should be pretty easy to customize using css. More information can be found here http://mrjsontable.azurewebsites.net/ and the project is available for you to do as you wish with on github https://github.com/MatchingRadar/Mr.JsonTable

To get it to work download the files and pop them in your site. Follow the instructions and you should end up with something like the following:

<div id="citytable"></div>

Then in the ajax success method you will want something like this

success: function(data){ 
    $("#citytable").mrjsontable({
        tableClass: "my-table",
        pageSize: 10, //you can change the page size here
        columns: [
            new $.fn.mrjsontablecolumn({
                heading: "City",
                data: "city"
            }),
            new $.fn.mrjsontablecolumn({
                heading: "City Status",
                data: "cStatus"
            })
        ],
        data: data
    });
}

Hope it helps somebody else!

I just solved this myself by:

git checkout -b tmp # "tmp" or pick a better name for your local changes branch
git add -A
git commit -m 'tmp'
git pull
git checkout master # Or whatever branch you were on originally
git pull
git diff tmp

where the last command gives a list of what your local changes were. Keep modifying the "tmp" branch until it is acceptable and then merge back onto master with:

git checkout master && git merge tmp

For next time, you can probably handle this in a cleaner way by looking up "git stash branch" though stash is likely to cause you trouble on the first few tries, so do first experiment on a non-critical project...

seems ok... though I'd think a rudimentary indication of success/failure/time posted/# bytes received/etc. would be preferable.

edit: I was thinking along the lines of data integrity and/or record-keeping; metadata such as an MD5 hash or timestamp for time received may be helpful for large datafiles.

const absolutePath = path.join(__dirname, some, dir);

vs.

const absolutePath = path.resolve(__dirname, some, dir);

path.join will concatenate __dirname which is the directory name of the current file concatenated with values of some and dir with platform-specific separator.

Whereas

path.resolve will process __dirname, some and dir i.e. from right to left prepending it by processing it.

If any of the values of some or dir corresponds to a root path then the previous path will be omitted and process rest by considering it as root

In order to better understand the concept let me explain both a little bit more detail as follows:-

The path.join and path.resolve are two different methods or functions of the path module provided by nodejs.

Where both accept a list of paths but the difference comes in the result i.e. how they process these paths.

path.join concatenates all given path segments together using the platform-specific separator as a delimiter, then normalizes the resulting path. While the path.resolve() process the sequence of paths from right to left, with each subsequent path prepended until an absolute path is constructed.

When no arguments supplied

The following example will help you to clearly understand both concepts:-

My filename is index.js and the current working directory is E:\MyFolder\Pjtz\node

const path = require('path');

console.log("path.join() : ", path.join());
// outputs .
console.log("path.resolve() : ", path.resolve());
// outputs current directory or equivalent to __dirname

Result

? node index.js
path.join() :  .
path.resolve() :  E:\MyFolder\Pjtz\node

path.resolve() method will output the absolute path whereas the path.join() returns . representing the current working directory if nothing is provided

When some root path is passed as arguments

const path=require('path');

console.log("path.join() : " ,path.join('abc','/bcd'));
console.log("path.resolve() : ",path.resolve('abc','/bcd'));

Result i

? node index.js
path.join() :  abc\bcd
path.resolve() :  E:\bcd

path.join() only concatenates the input list with platform-specific separator while the path.resolve() process the sequence of paths from right to left, with each subsequent path prepended until an absolute path is constructed.

Another PHP answer to make lives easier. Updated for Facebook Graph API 2.9 . Just fill 'er up and load.

<?php
$args=[
/*-- Permanent access token generator for Facebook Graph API version 2.9 --*/
//Instructions: Fill Input Area below and then run this php file
/*-- INPUT AREA START --*/
    'usertoken'=>'',
    'appid'=>'',
    'appsecret'=>'',
    'pageid'=>''
/*-- INPUT AREA END --*/
];
echo 'Permanent access token is: <input type="text" value="'.generate_token($args).'"></input>';
function generate_token($args){
    $r=json_decode(file_get_contents("https://graph.facebook.com/v2.9/oauth/access_token?grant_type=fb_exchange_token&client_id={$args['appid']}&client_secret={$args['appsecret']}&fb_exchange_token={$args['usertoken']}")); // get long-lived token
    $longtoken=$r->access_token;
    $r=json_decode(file_get_contents("https://graph.facebook.com/v2.9/me?access_token={$longtoken}")); // get user id
    $userid=$r->id;
    $r=json_decode(file_get_contents("https://graph.facebook.com/v2.9/{$userid}?fields=access_token&access_token={$longtoken}")); // get permanent token
    if($r->id==$args['pageid']) $finaltoken=$r->access_token;
    return $finaltoken;
}
?>

Addendum: (alternative)

Graph 2.9 onwards , you can skip much of the hassle of getting a long access token by simply clicking Extend Access Token at the bottom of the Access Token Debugger tool, after having debugged a short access token. Armed with information about pageid and longlivedtoken, run the php below to get permanent access token.

<?php
$args=[
/*-- Permanent access token generator for Facebook Graph API version 2.9 --*/
//Instructions: Fill Input Area below and then run this php file
/*-- INPUT AREA START --*/
    'longlivedtoken'=>'',
    'pageid'=>''
/*-- INPUT AREA END --*/
];
echo 'Permanent access token is: <input type="text" value="'.generate_token($args).'"></input>';
function generate_token($args){
$r=json_decode(file_get_contents("https://graph.facebook.com/v2.9/{$args['pageid']}?fields=access_token&access_token={$args['longlivedtoken']}"));
return $r->access_token;
}
?>

Although the second code saves you a lot of hassle, I recommend running the first php code unless you are in a lot of hurry because it cross-checks pageid and userid. The second code will not end up working if you choose user token by mistake.

Thanks to dw1 and Rob

you can also use this

if (SQLCON.State == ConnectionState.Closed)
{
     SQLCON.Open();
}

you can still use

String Item = getIntent().getExtras().getString("name");

in the fragment, you just need call getActivity() first:

String Item = getActivity().getIntent().getExtras().getString("name");

This saves you having to write some code.

You can create table variables:

DECLARE @result1 TABLE (a INT, b INT, c INT)

INSERT INTO @result1
SELECT a, b, c
FROM table1

SELECT a AS val FROM @result1
UNION
SELECT b AS val FROM @result1
UNION
SELECT c AS val FROM @result1

This should be fine for what you need.

int variables can't be null

If a null is to be converted to int, then it is the converter which decides whether to set 0, throw exception, or set another value (like Integer.MIN_VALUE). Try to plug your own converter.

Recently I experienced a problem using optimization with g++. The problem was related to a PCI card, where the registers (for command and data) were repreented by a memory address. My driver mapped the physical address to a pointer within the application and gave it to the called process, which worked with it like this:

unsigned int * pciMemory;
askDriverForMapping( & pciMemory );
...
pciMemory[ 0 ] = someCommandIdx;
pciMemory[ 0 ] = someCommandLength;
for ( int i = 0; i < sizeof( someCommand ); i++ )
    pciMemory[ 0 ] = someCommand[ i ];

The card didn't act as expected. When I saw the assembly I understood that the compiler only wrote someCommand[ the last ] into pciMemory, omitting all preceding writes.

In conclusion: be accurate and attentive with optimization.

Late answer, but you can take advantage of the fact that you can deserialize multiple objects from one JSON string, as long as the objects don't share any common property names,

    public async Task<HttpResponseMessage> Post(HttpRequestMessage request)
    {
        var jsonString = await request.Content.ReadAsStringAsync();
        var content  = JsonConvert.DeserializeObject<Content >(jsonString);
        var config  = JsonConvert.DeserializeObject<Config>(jsonString);
    }

You Can Try this

import ftplib

path = 'pub/Health_Statistics/NCHS/nhanes/2001-2002/'
filename = 'L28POC_B.xpt'

ftp = ftplib.FTP("Server IP") 
ftp.login("UserName", "Password") 
ftp.cwd(path)
ftp.retrbinary("RETR " + filename, open(filename, 'wb').write)
ftp.quit()

Suppose originally there were 3 commits, A,B,C:

Then developer Dan created commit D, and developer Ed created commit E:

Obviously, this conflict should be resolved somehow. For this, there are 2 ways:

MERGE:

Both commits D and E are still here, but we create merge commit M that inherits changes from both D and E. However, this creates diamond shape, which many people find very confusing.

REBASE:

We create commit R, which actual file content is identical to that of merge commit M above. But, we get rid of commit E, like it never existed (denoted by dots - vanishing line). Because of this obliteration, E should be local to developer Ed and should have never been pushed to any other repository. Advantage of rebase is that diamond shape is avoided, and history stays nice straight line - most developers love that!

I usually just remove all quotes from my variables with:

set var=%var:"=%

And then apply them again wherever I need them e.g.:

echo "%var%"

Here I present an alias based on Richard Hansen's answer (and Ben C's suggestion), but that I adapted to exclude tags. The alias should be fairly robust.

# For Git 1.22+
git config --global alias.only '!b=${1:-$(git branch --show-current)}; git log --oneline --graph "heads/$b" --not --exclude="$b" --branches --remotes #'
# For older Git:
git config --global alias.only '!b=${1:-$(git symbolic-ref -q --short HEAD)}; b=${b##heads/}; git log --oneline --graph "heads/$b" --not --exclude="$b" --branches --remotes #'

Example of use:

git only mybranch  # Show commits that are in mybranch ONLY
git only           # Show commits that are ONLY in current branch

Note that ONLY means commits that would be LOST (after garbage collection) if the given branch was deleted (excluding the effect of tags). The alias should work even if there is unfortunately a tag named mybranch (thanks to prefix heads/). Note also that no commits are shown if they are part of any remote branch (including upstream if any), in compliance with the definition of ONLY.

The alias shows the one-line history as a graph of the selected commits.

  a --- b --- c --- master
   \           \
    \           d
     \           \
      e --- f --- g --- mybranch (HEAD)
       \
        h --- origin/other

With example above, git only would show:

  * (mybranch,HEAD)
  * g
  |\
  | * d
  * f 

In order to include tags (but still excluding HEAD), the alias becomes (adapt as above for older Git):

git config --global alias.only '!b=${1:-$(git branch --show-current)};  git log --oneline --graph --all --not --exclude="refs/heads/$b" --exclude=HEAD --all #'

Or the variant that includes all the tags including HEAD (and removing current branch as default since it won't output anything):

git config --global alias.only '!git log --oneline --graph --all --not --exclude=\"refs/heads/$1\" --all #'

This last version is the only one that really satisfies the criteria commits-that-are-lost-if-given-branch-is-deleted, since a branch cannot be deleted if it is checked out, and no commit pointed by HEAD or any other tag will be lost. However the first two variants are more useful.

Finally, the alias does not work with remote branches (eg. git only origin/master). The alias must be modified, for instance:

git config --global alias.remote-only '!git log --oneline --graph "$1" --not --exclude="$1" --remotes --branches #'

I tried the below code,

    function executeQuery() {
  $.ajax({
    url: 'url/path/here',
    success: function(data) {
      // do something with the return value here if you like
    }
  });
  setTimeout(executeQuery, 5000); // you could choose not to continue on failure...
}

$(document).ready(function() {
  // run the first time; all subsequent calls will take care of themselves
  setTimeout(executeQuery, 5000);
});

This didn't work as expected for the specified interval,the page didn't load completely and the function was been called continuously. Its better to call setTimeout(executeQuery, 5000); outside executeQuery() in a separate function as below,

function executeQuery() {
  $.ajax({
    url: 'url/path/here',
    success: function(data) {
      // do something with the return value here if you like
    }

function updateCall(){
setTimeout(function(){executeQuery()}, 5000);
}

$(document).ready(function() {
  executeQuery();
});

This worked exactly as intended.

In bootstrap v4, the navigation can be collapsed sooner or later using different css classes

eg:

• navbar-toggleable-sm
• navbar-toggleable-md
• navbar-toggleable-lg

With the button for the navigation:

• hidden-sm-up
• hidden-md-up
• hidden-lg-up

This issue can be solved using MediaQuery.of(context)

To get Screen width: MediaQuery.of(context).size.width

To get Screen height: MediaQuery.of(context).size.height

In a functional language, tail call optimization is as if a function call could return a partially evaluated expression as the result, which would then be evaluated by the caller.

f x = g x

f 6 reduces to g 6. So if the implementation could return g 6 as the result, and then call that expression it would save a stack frame.

Also

f x = if c x then g x else h x.

Reduces to f 6 to either g 6 or h 6. So if the implementation evaluates c 6 and finds it is true then it can reduce,

if true then g x else h x ---> g x

f x ---> h x

A simple non tail call optimization interpreter might look like this,

class simple_expresion
{
    ...
public:
    virtual ximple_value *DoEvaluate() const = 0;
};

class simple_value
{
    ...
};

class simple_function : public simple_expresion
{
    ...
private:
    simple_expresion *m_Function;
    simple_expresion *m_Parameter;

public:
    virtual simple_value *DoEvaluate() const
    {
        vector<simple_expresion *> parameterList;
        parameterList->push_back(m_Parameter);
        return m_Function->Call(parameterList);
    }
};

class simple_if : public simple_function
{
private:
    simple_expresion *m_Condition;
    simple_expresion *m_Positive;
    simple_expresion *m_Negative;

public:
    simple_value *DoEvaluate() const
    {
        if (m_Condition.DoEvaluate()->IsTrue())
        {
            return m_Positive.DoEvaluate();
        }
        else
        {
            return m_Negative.DoEvaluate();
        }
    }
}

A tail call optimization interpreter might look like this,

class tco_expresion
{
    ...
public:
    virtual tco_expresion *DoEvaluate() const = 0;
    virtual bool IsValue()
    {
        return false;
    }
};

    tco_expresion *m_Parameter;

public:

sum.up is not a valid keyword argument name. Keyword arguments must be valid identifiers. You should look in the documentation of the library you are using how this argument really is called – maybe sum_up?

The following will give you an array of the type you want while preserving type safety.

PCB[] getAll(Class<PCB[]> arrayType) {  
    PCB[] res = arrayType.cast(java.lang.reflect.Array.newInstance(arrayType.getComponentType(), list.size()));  
    for (int i = 0; i < res.length; i++)  {  
        res[i] = list.get(i);  
    }  
    list.clear();  
    return res;  
}

How this works is explained in depth in my answer to the question that Kirk Woll linked as a duplicate.

Use \overleftarrow to create a long arrow to the left.

\overleftarrow{blahblahblah}

on sql 2008 this is valid

DECLARE @myVariable nvarchar(Max) = 'John said to Emily "Hey there Emily"'
select @myVariable

on sql server 2005, you need to do this

DECLARE @myVariable nvarchar(Max) 
select @myVariable = 'John said to Emily "Hey there Emily"'
select @myVariable

asp:TextBox ID="txtName" placeholder="any text here"

Try like this.It should work

Response.Redirect(String.Format("yourpage.aspx?strId={0}&strName={1}&strDate{2}", Server.UrlEncode(strId), Server.UrlEncode(strName),Server.UrlEncode(strDate)));

The solution I use is the following:

<input list="answers" id="answer">
<datalist id="answers">
  <option data-value="42" value="The answer">
</datalist>

Then access the value to be sent to the server using JavaScript like this:

var shownVal = document.getElementById("answer").value;
var value2send = document.querySelector("#answers option[value='"+shownVal+"']").dataset.value;

Hope it helps.

There's no good reason for 1 to be true and 0 to be false; that's just the way things have always been notated. So from a logical perspective, the function in your API isn't "wrong", per se.

That said, it's normally not advisable to work against the idioms of whatever language or framework you're using without a damn good reason to do so, so whoever wrote this function was probably pretty bone-headed, assuming it's not simply a bug.

$datetime = date("Y-m-d h:i:s");
$timestamp = strtotime($datetime);
$image = $_POST['image'];
$imgdata = base64_decode($image);
$f = finfo_open();
$mime_type = finfo_buffer($f, $imgdata, FILEINFO_MIME_TYPE);
$temp=explode('/',$mime_type);
$path = "uploads/$timestamp.$temp[1]";
file_put_contents($path,base64_decode($image));
echo "Successfully Uploaded->>> $timestamp.$temp[1]";

This will be enough for image processing. Special thanks to Mr. Dev Karan Sharma

Spending about 4 hours on googling and stackoverflowing, trying all of stuff around there, i've found my error:

My mapping file was called .nbm.xml instead of .hbm.xml. That was insane.

String dt = Date.Now.ToString("yyyy-MM-dd");

Now you got this for dt, 2010-09-09

You cannot add JavaScript variable to HTML code.

For this you need to do in following way.

<html>
<head>
<script type="text/javscript">
var number = 123;

document.addEventListener('DOMContentLoaded', function() {
   document.getElementByTagName("h1").innerHTML("the value for number is: " + number);
});
</script>
</head>
<body>
<h1></h1>
</body>
</html>

Better yet, use union to grab all the rows you want to delete, then delete them all at once. The rows need not be continuous.

dim rng as range
dim rDel as range

for each rng in {the range you're searching}
   if {Conditions to be met} = true then
      if not rDel is nothing then
         set rDel = union(rng,rDel)
      else
         set rDel = rng
      end if
   end if
 next
 
 rDel.entirerow.delete

That way you don't have to worry about sorting or things being at the bottom.

Did you import the packages for the file reading stuff.

import java.io.BufferedReader;
import java.io.FileInputStream;
import java.io.InputStreamReader;

also here

cfiltering(numberOfUsers, numberOfMovies);

Are you trying to create an object or calling a method?

also another thing:

user_movie_matrix[userNo][movieNo]=rating;

you are assigning a value to a member of an instance as if it was a static variable also remove the Th in

private int user_movie_matrix[][];Th

Hope this helps.

Another case of R. breakage is Annotations Processing.

Some processing could refer to classes located in certain folders or folder levels. If you move required classes to other location, you can get R. as an unknown class.

How to escape single quotes (') and double quotes (") with hex and octal chars

If using something like echo, I've had some really complicated and really weird and hard-to-escape (think: very nested) cases where the only thing I could get to work was using octal or hex codes!

Here are some examples:

1. Single quote example, where ' is escaped with hex \x27 or octal \047 (its corresponding ASCII code):

# 1. hex
$ echo -e "Let\x27s get coding!"
Let's get coding!

# 2. octal
$ echo -e "Let\047s get coding!"
Let's get coding!

2. Double quote example, where " is escaped with hex \x22 or octal \042 (its corresponding ASCII code).

Note: bash is nuts! Sometimes even the ! char has special meaning, and must either be removed from within the double quotes and then escaped "like this"\! or put entirely within single quotes 'like this!', rather than within double quotes.

# 1. hex; escape `!` by removing it from within the double quotes 
# and escaping it with `\!`
$ echo -e "She said, \x22Let\x27s get coding"\!"\x22"
She said, "Let's get coding!"

# OR put it all within single quotes:
$ echo -e 'She said, \x22Let\x27s get coding!\x22'
She said, "Let's get coding!"


# 2. octal; escape `!` by removing it from within the double quotes 
$ echo -e "She said, \042Let\047s get coding"\!"\042"
She said, "Let's get coding!"

# OR put it all within single quotes:
$ echo -e 'She said, \042Let\047s get coding!\042'
She said, "Let's get coding!"


# 3. mixed hex and octal, just for fun
# escape `!` by removing it from within the double quotes when it is followed by
# another escape sequence
$ echo -e "She said, \x22Let\047s get coding! It\x27s waaay past time to begin"\!"\042"
She said, "Let's get coding! It's waaay past time to begin!"

# OR put it all within single quotes:
$ echo -e 'She said, \x22Let\047s get coding! It\x27s waaay past time to begin!\042'
She said, "Let's get coding! It's waaay past time to begin!"

Note that if you don't properly escape !, when needed, as I've shown two ways to do above, you'll get some weird errors, like this:

$ echo -e "She said, \x22Let\047s get coding! It\x27s waaay past time to begin!\042"
bash: !\042: event not found

OR:

$ echo -e "She said, \x22Let\x27s get coding!\x22"
bash: !\x22: event not found

You want to restrict to input fields that are of type text so use the selector input[type=text] rather than input (which will apply to all input fields (e.g. those of type submit as well)).

You can define a simple method like:

public enum Alphabet{
    A,B,C,D;

    public static Alphabet get(int index){
        return Alphabet.values()[index];
    }
}

And use it like:

System.out.println(Alphabet.get(2));

You can use this code:

int count;
            try {
                URL url = new URL(f_url[0]);
                URLConnection conection = url.openConnection();
                conection.setConnectTimeout(TIME_OUT);
                conection.connect();
                // Getting file length
                int lenghtOfFile = conection.getContentLength();
                // Create a Input stream to read file - with 8k buffer
                InputStream input = new BufferedInputStream(url.openStream(),
                        8192);
                // Output stream to write file
                OutputStream output = new FileOutputStream(
                        "/sdcard/9androidnet.jpg");

                byte data[] = new byte[1024];
                long total = 0;
                while ((count = input.read(data)) != -1) {
                    total += count;
                    // publishing the progress....
                    // After this onProgressUpdate will be called
                    publishProgress("" + (int) ((total * 100) / lenghtOfFile));
                    // writing data to file
                    output.write(data, 0, count);
                }
                // flushing output
                output.flush();
                // closing streams
                output.close();
                input.close();
            } catch (SocketTimeoutException e) {
                connectionTimeout=true;
            } catch (Exception e) {
                Log.e("Error: ", e.getMessage());
            }

The third parameter of String.prototype.replace() function was never defined as a standard, so most browsers simply do not implement it.

The best way is to use regular expression with g (global) flag.

var myStr = 'this,is,a,test';_x000D_
var newStr = myStr.replace(/,/g, '-');_x000D_
_x000D_
console.log( newStr );  // "this-is-a-test"

Still have issues?

It is important to note, that regular expressions use special characters that need to be escaped. As an example, if you need to escape a dot (.) character, you should use /\./ literal, as in the regex syntax a dot matches any single character (except line terminators).

var myStr = 'this.is.a.test';_x000D_
var newStr = myStr.replace(/\./g, '-');_x000D_
_x000D_
console.log( newStr );  // "this-is-a-test"

If you need to pass a variable as a replacement string, instead of using regex literal you may create RegExp object and pass a string as the first argument of the constructor. The normal string escape rules (preceding special characters with \ when included in a string) will be necessary.

var myStr = 'this.is.a.test';_x000D_
var reStr = '\\.';_x000D_
var newStr = myStr.replace(new RegExp(reStr, 'g'), '-');_x000D_
_x000D_
console.log( newStr );  // "this-is-a-test"

You can do it from adb using this command:

adb shell am start -a android.intent.action.DELETE -d package:<your app package>

You can use python's built-in function sum

• sum will return the sum of all the values
• len to get list's length

code:

>>> list = [1,2,3,4]
>>> sum(list)
>>> 10
>>> len(list)
>>> 4
>>> avg = float(sum(list))/len(list)
>>> 2.5
>>>"""In pyton3 don't want to specify float"""
>>> 10 / 4
>>> 2.5 

Use float because when using python 2.x, because:

• int/int returns int value (i.e. 2)
• float/int returns float value (i.e. 2.5)

While in Python 3.x:

• int/int return float
• int//int return int

This is what I do on debian - I suspect it should work on ubuntu (amend the version as required + adapt the folder where you want to copy the JDK files as you wish, I'm using /opt/jdk):

wget --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u71-b15/jdk-8u71-linux-x64.tar.gz
sudo mkdir /opt/jdk
sudo tar -zxf jdk-8u71-linux-x64.tar.gz -C /opt/jdk/
rm jdk-8u71-linux-x64.tar.gz

Then update-alternatives:

sudo update-alternatives --install /usr/bin/java java /opt/jdk/jdk1.8.0_71/bin/java 1
sudo update-alternatives --install /usr/bin/javac javac /opt/jdk/jdk1.8.0_71/bin/javac 1

Select the number corresponding to the /opt/jdk/jdk1.8.0_71/bin/java when running the following commands:

sudo update-alternatives --config java
sudo update-alternatives --config javac

Finally, verify that the correct version is selected:

java -version
javac -version

There is one another method of temp table

create table #TempTable (
ID int,
name varchar(max)
)

insert into #TempTable (ID,name)
Select ID,Name 
from Table

SELECT * 
FROM #TempTable
WHERE ID  = 1 

Make Sure You are selecting the right database.

Change It like this, It worked for me. Hope It helps. firs I did

$cfg['Servers'][$i]['verbose'] = 'mysql wampserver';
//$cfg['Servers'][$i]['auth_type'] = 'cookie';
$cfg['Servers'][$i]['auth_type'] = 'config';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = 'changed';
/* Server parameters */
$cfg['Servers'][$i]['host'] = '127.0.0.1';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['compress'] = false;
/* Select mysql if your server does not have mysqli */
$cfg['Servers'][$i]['extension'] = 'mysqli';
$cfg['Servers'][$i]['AllowNoPassword'] = false;

Then I Changed Like this...

$cfg['Servers'][$i]['verbose'] = 'mysql wampserver';
//$cfg['Servers'][$i]['auth_type'] = 'cookie';
$cfg['Servers'][$i]['auth_type'] = 'config';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = 'root';
/* Server parameters */
$cfg['Servers'][$i]['host'] = '127.0.0.1';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['compress'] = false;
/* Select mysql if your server does not have mysqli */
$cfg['Servers'][$i]['extension'] = 'mysqli';
$cfg['Servers'][$i]['AllowNoPassword'] = false;

The "super.init()" should be called after you initialize all your instance variables.

In Apple's "Intermediate Swift" video (you can find it in Apple Developer video resource page https://developer.apple.com/videos/wwdc/2014/), at about 28:40, it is explicit said that all initializers in super class must be called AFTER you initialize your instance variables.

In Objective-C, it was the reverse. In Swift, since all properties need to be initialized before it's used, we need to initialize properties first. This is meant to prevent a call to overrided function from super class's "init()" method, without initializing properties first.

So the implementation of "Square" should be:

class Square: Shape {
    var sideLength: Double

    init(sideLength:Double, name:String) {
        self.sideLength = sideLength
        numberOfSides = 4
        super.init(name:name) // Correct position for "super.init()"
    }
    func area () -> Double {
        return sideLength * sideLength
    }
}

Ok, finally found the solution.

Probably due to lack of experience with ReactJS and web development...

    var Task = React.createClass({
    render: function() {
      var percentage = this.props.children + '%';
      ....
        <div className="ui-progressbar-value ui-widget-header ui-corner-left" style={{width : percentage}}/>
      ...

I created the percentage variable outside in the render function.

Provide an XML API to access your data; in a manner that is simple to use. If people want your data, they'll get it, you might as well go all out.

This way you can provide a subset of functionality in an effective manner, ensuring that, at the very least, the scrapers won't guzzle up HTTP requests and massive amounts of bandwidth.

Then all you have to do is convince the people who want your data to use the API. ;)

Usually, I don't care about the order of the calls, only that they happened. In that case, I combine assert_any_call with an assertion about call_count.

>>> import mock
>>> m = mock.Mock()
>>> m(1)
<Mock name='mock()' id='37578160'>
>>> m(2)
<Mock name='mock()' id='37578160'>
>>> m(3)
<Mock name='mock()' id='37578160'>
>>> m.assert_any_call(1)
>>> m.assert_any_call(2)
>>> m.assert_any_call(3)
>>> assert 3 == m.call_count
>>> m.assert_any_call(4)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "[python path]\lib\site-packages\mock.py", line 891, in assert_any_call
    '%s call not found' % expected_string
AssertionError: mock(4) call not found

I find doing it this way to be easier to read and understand than a large list of calls passed into a single method.

If you do care about order or you expect multiple identical calls, assert_has_calls might be more appropriate.

Edit

Since I posted this answer, I've rethought my approach to testing in general. I think it's worth mentioning that if your test is getting this complicated, you may be testing inappropriately or have a design problem. Mocks are designed for testing inter-object communication in an object oriented design. If your design is not objected oriented (as in more procedural or functional), the mock may be totally inappropriate. You may also have too much going on inside the method, or you might be testing internal details that are best left unmocked. I developed the strategy mentioned in this method when my code was not very object oriented, and I believe I was also testing internal details that would have been best left unmocked.

You can also use update ... from syntax and use a mapping table. If you want to update more than one column, it's much more generalizable:

update test as t set
    column_a = c.column_a
from (values
    ('123', 1),
    ('345', 2)  
) as c(column_b, column_a) 
where c.column_b = t.column_b;

You can add as many columns as you like:

update test as t set
    column_a = c.column_a,
    column_c = c.column_c
from (values
    ('123', 1, '---'),
    ('345', 2, '+++')  
) as c(column_b, column_a, column_c) 
where c.column_b = t.column_b;

This answer is not solely related with flask, but should be applicable for all cannot connect service from another host issue.

1. use netstat -ano | grep <port> to see if the address is 0.0.0.0 or ::. If it is 127.0.0.1 then it is only for the local requests.
2. use tcpdump to see if any packet is missing. If it shows obvious imbalance, check routing rules by iptables.

Today I run my flask app as usual, but I noticed it cannot connect from other server. Then I run netstat -ano | grep <port>, and the local address is :: or 0.0.0.0 (I tried both, and I know 127.0.0.1 only allows connection from the local host). Then I used telnet host port, the result is like connect to .... This is very odd. Then I thought I would better check it with tcpdump -i any port <port> -w w.pcap. And I noticed it is all like this:

Then by checking iptables --list OUTPUT section, I could see several rules:

these rules forbid output tcp vital packets in handshaking. By deleting them, the problem is gone.

Out of all the combinations you tried, %ld and %lu are the only ones which are valid printf format specifiers at all. %lu (long unsigned decimal), %lx or %lX (long hex with lowercase or uppercase letters), and %lo (long octal) are the only valid format specifiers for a variable of type unsigned long (of course you can add field width, precision, etc modifiers between the % and the l).

As a follow up to Nick Fortescue's answer, here's a more complete example of how to record from the microphone and process the resulting data:

    return max(snd_data) < THRESHOLD

def normalize(snd_data):
    "Average the volume out"
    MAXIMUM = 16384
    times = float(MAXIMUM)/max(abs(i) for i in snd_data)

    r = array('h')
    for i in snd_data:
        r.append(int(i*times))

I'm quite a beginner in Python and I found the answer of Anand was very good but quite complicated to me, so I try to reformulate :

1) insert and append methods are not specific to sys.path and as in other languages they add an item into a list or array and :
* append(item) add item to the end of the list,
* insert(n, item) inserts the item at the nth position in the list (0 at the beginning, 1 after the first element, etc ...).

2) As Anand said, python search the import files in each directory of the path in the order of the path, so :
* If you have no file name collisions, the order of the path has no impact,
* If you look after a function already defined in the path and you use append to add your path, you will not get your function but the predefined one.

But I think that it is better to use append and not insert to not overload the standard behaviour of Python, and use non-ambiguous names for your files and methods.

current time and date in android with the format

Calendar c = Calendar.getInstance();
System.out.println("Current dateTime => " + c.getTime());
SimpleDateFormat df = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss a");
String formattedDate = df.format(c.getTime());
System.out.println("Format dateTime => " + formattedDate);

output

I/System.out: Current dateTime => Wed Feb 26 02:58:17 GMT+05:30 2020

7 years passed and...
actually there's this new SQL Server 2016 feature that does exactly what you need.
It is called AT TIME ZONE and it converts date to a specified time zone considering DST (daylight saving time) changes.

My error occurred because, somehow, there was an obj folder created inside my controllers folder. Just do a search in your application for a line inside your Assemblyinfo.cs. There may be a duplicate somewhere.

a <div> is a logical division in your content, semantically this would be my first choice if I wanted to group the heading with the list:

<div class="mydiv">
    <h3>The heading</h3>
    <ul>
       <li>item</li>
       <li>item</li>
       <li>item</li>
    </ul>
</div>

then you can use the following css to style everything together as one unit

.mydiv{}
.mydiv h3{}
.mydiv ul{}
.mydiv ul li{}
etc...

It doesn't seem to trigger DocumentCompleted/Navigated events for external Javascript or CSS files, but it will for iframes. As PK says, compare the WebBrowserDocumentCompletedEventArgs.Url property (I don't have the karma to make a comment yet).

controlName.CssClass="CSS Class Name";

working example follows below

txtBank.CssClass = "csError";

def is_prime(x):
    n = 2
    if x < n:
        return False
    else:    
        while n < x:
           print n
            if x % n == 0:
                return False
                break
            n = n + 1
        else:
            return True

I recently switch to set strict-mode -version 2.0 and my null tests failed.

I added a function:

#use in strict mode to validate property exists before using
function exists {
  param($obj,$prop)
  try {
    if ($null -ne $obj[$prop]) {return $true}
    return $false
  } catch {
    return $false
  }
  return $false
}

Now I code

if (exists $run main) { ...

rather than

if ($run.main -ne $null) { ...

and we are on our way. Seems to work on objects and hashtables

As an unintended benefit it is less typing.

This should do when your date is in this format (dd/mm/yyyy).

  sortByDate(arr) {
    arr.sort(function(a,b){
      return Number(new Date(a.readableDate)) - Number(new Date(b.readableDate));
    });

    return arr;
  }

Then call sortByDate(myArr);

1. Iterating over a Python dict means to iterate over its keys exactly the same way as with dict.keys()
2. The order of the keys is determined by the implementation code and you cannot expect some specific order:

   Keys and values are iterated over in an arbitrary order which is non-random, varies across Python implementations, and depends on the dictionary’s history of insertions and deletions. If keys, values and items views are iterated over with no intervening modifications to the dictionary, the order of items will directly correspond.

That's why you see the indices 0 to 7 in the first column. They are produced by enumerate and are always in the correct order. Further you see the dict's keys 0 to 7 in the second column. They are not sorted.

simply use the Out-File cmd but DON'T forget to give an encoding type: -Encoding UTF8

so use it so:

$log | Out-File -Append C:\as\whatever.csv -Encoding UTF8

-Append is required if you want to write in the file more then once.

For the Platform Independent Users or Windows users, what you can do is:

import runtime:

import (
    "runtime"
    "strings"
)

and then trim the string like this:

if runtime.GOOS == "windows" {
  input = strings.TrimRight(input, "\r\n")
} else {
  input = strings.TrimRight(input, "\n")
}

now you can compare it like that:

if strings.Compare(input, "a") == 0 {
  //....yourCode
}

This is a better approach when you're making use of STDIN on multiple platforms.

Explanation

This happens because on windows lines end with "\r\n" which is known as CRLF, but on UNIX lines end with "\n" which is known as LF and that's why we trim "\n" on unix based operating systems while we trim "\r\n" on windows.

I've been able to solve this by using a hack involving import *. It even works for both named and default exports!

For a named export:

// dependency.js
export const doSomething = (y) => console.log(y)

// myModule.js
import { doSomething } from './dependency';

export default (x) => {
  doSomething(x * 2);
}

// myModule-test.js
import myModule from '../myModule';
import * as dependency from '../dependency';

describe('myModule', () => {
  it('calls the dependency with double the input', () => {
    dependency.doSomething = jest.fn(); // Mutate the named export

    myModule(2);

    expect(dependency.doSomething).toBeCalledWith(4);
  });
});

Or for a default export:

// dependency.js
export default (y) => console.log(y)

// myModule.js
import dependency from './dependency'; // Note lack of curlies

export default (x) => {
  dependency(x * 2);
}

// myModule-test.js
import myModule from '../myModule';
import * as dependency from '../dependency';

describe('myModule', () => {
  it('calls the dependency with double the input', () => {
    dependency.default = jest.fn(); // Mutate the default export

    myModule(2);

    expect(dependency.default).toBeCalledWith(4); // Assert against the default
  });
});

As Mihai Damian quite rightly pointed out below, this is mutating the module object of dependency, and so it will 'leak' across to other tests. So if you use this approach you should store the original value and then set it back again after each test.

To do this easily with Jest, use the spyOn() method instead of jest.fn(), because it supports easily restoring its original value, therefore avoiding before mentioned 'leaking'.

public  static byte[][] arrayCopy(byte[][] arr){
    if(arr!=null){
        int[][] arrCopy = new int[arr.length][] ;
        System.arraycopy(arr, 0, arrCopy, 0, arr.length);
        return arrCopy;
    }else { return new int[][]{};}
}

I'm trying to setup rf online game to be played offline using MS SQL server 2019 and ended up with the same problem. The SQL Browser service won't start. Almost all answers in this post have been tried but the outcome is disappointing. I've got a weird idea to try start the SQL browser service manually and then change it to automatic after it runs. Luckily it works. So, just simply right click on SQL Server Browser ==> Properties ==>Service==>Start Mode==>Manual. After apply the changes right click on the SQL Server Browser again and start the service. After the service run change the start mode to automatic. Make sure the information provided on log on as: are correct.

a.button a:hover means "a link that's being hovered over that is a child of a link with the class button".

Go instead for a.button:hover.

If you do not need to have the database directories in root, you can create data/db in your home directory (mkdir -p ~/data/db).

Then you can start the MongoDB server with the --dbpath option:

mongod --dbpath=$(echo ~)/data/db

(This is assuming you're starting it from a terminal. For some strange reason, mongod does not accept ~ as the home directory path, hence the bash echo substitution trickery, you may as well write /home/yourusername/data/db)

In fact, it does not have to be ~/data/db, it can be anywhere you want and this way you can have multiple database paths and organize everything nicely. May not be the best option for production (depending on what you want to do), but for developing works fine.

To add to the chunk of window that seems to cut off at the bottom, especially when you don't have scrolling I used:

function resizeIframe(iframe) {
    var addHeight = 20; //or whatever size is being cut off
    iframe.height = iframe.contentWindow.document.body.scrollHeight + addHeight + "px";
  }

If your goal is to initialize the static variable in your header file (instead of a *.cpp file, which you may want if you are sticking to a "header only" idiom), then you can work around the initialization problem by using a template. Templated static variables can be initialized in a header, without causing multiple symbols to be defined.

See here for an example:

Static member initialization in a class template

I'll slightly expand @assylias answer to take time zone into account. There are at least two ways to get LocalDateTime for specific time zone.

You can use setDefault time zone for whole application. It should be called before any timestamp -> java.time conversion:

public static void main(String... args) {
    TimeZone utcTimeZone = TimeZone.getTimeZone("UTC");
    TimeZone.setDefault(utcTimeZone);
    ...
    timestamp.toLocalDateTime().toLocalDate();
}

Or you can use toInstant.atZone chain:

timestamp.toInstant()
        .atZone(ZoneId.of("UTC"))
        .toLocalDate();

If you want to be sure to not have to deal with quotes for the syntax stash@{x}, use Git 2.11 (Q4 2016)

stash: allow stashes to be referenced by index only

Instead of referencing "stash@{n}" explicitly, make it possible to simply reference as "n".
Most users only reference stashes by their position in the stash stack (what I refer to as the "index" here).

The syntax for the typical stash (stash@{n}) is slightly annoying and easy to forget, and sometimes difficult to escape properly in a script.

Because of this the capability to do things with the stash by simply referencing the index is desirable.

So:

git stash drop 1
git stash pop 1
git stash apply 1
git stash show 1

1st put "yourmp3file".mp3 file in the raw folder(ie inside Res folder)

2nd in your code put..

Notification noti = new Notification.Builder(this)
.setSound(Uri.parse("android.resource://" + v.getContext().getPackageName() + "/" + R.raw.yourmp3file))//*see note

This is what i put inside my onClick(View v) as only "context().getPackageName()" wont work from there as it wont get any context

Vertical alignment only works with inline or inline-block elements, and it's only relative to other inline[-block] elements. Because you float the label, it becomes a block element.

The simplest solution in your case is to set the label to display: inline-block and add vertical-align: middle to the labels and the inputs. (You might find that the height of the text is such that vertical align won't make any difference anyway.)

I noticed that there is another CSS selector that does the same thing . The syntax is as follows :

[id|="name_id"]

This will select all elements ID which begins with the word enclosed in double quotes.

You can get column type of DataTable with DataType attribute of datatable column like below:

var type = dt.Columns[0].DataType

dt : DataTable object.

0 : DataTable column index.

For Jackson 2+ (com.fasterxml.jackson), the methods are little bit different:

Iterator<Entry<String, JsonNode>> nodes = rootNode.get("foo").fields();

while (nodes.hasNext()) {
  Map.Entry<String, JsonNode> entry = (Map.Entry<String, JsonNode>) nodes.next();

  logger.info("key --> " + entry.getKey() + " value-->" + entry.getValue());
}

met% python -c 'import this' | grep 'only one'
There should be one-- and preferably only one --obvious way to do it.

A constant reference to an object is not a constant, it's just a constant reference to an object.

private static final is not what defines something to be a constant or not. It's just the Java way to define a constant, but it doesn't mean that every private static final declaration was put there to define a constant.

When I write private static final Logger I'm not trying to define a constant, I'm just trying to define a reference to an object that is private (that it is not accessible from other classes), static (that it is a class level variable, no instance needed) and final (that can only be assigned once). If it happens to coincide with the way Java expects you to declare a constant, well, bad luck, but it doesn't make it a constant. I don't care what the compiler, sonar, or any Java guru says. A constant value, like MILLISECONDS_IN_A_SECOND = 1000 is one thing, and a constant reference to an object is another.

Gold is known to shine, but not everything that shines is gold.

I think some of the people answering this question don’t actually try to do what they recommend, because there is something wrong with way the Mac OS version handles the windows.

When you choose the new color scheme and click OK, the preferences window looks like it closed, but it is still there behind the main spyder window. You need to switch windows with command ~ or move the main spyder window to expose the preferences window. Then you need to click Apply to get the new color scheme.

You should use something like this pg_dump --schema=your_schema_name db1, for details take a look here

fill_parent :

A component is arranged layout for the fill_parent will be mandatory to expand to fill the layout unit members, as much as possible in the space. This is consistent with the dockstyle property of the Windows control. A top set layout or control to fill_parent will force it to take up the entire screen.

wrap_content

Set up a view of the size of wrap_content will be forced to view is expanded to show all the content. The TextView and ImageView controls, for example, is set to wrap_content will display its entire internal text and image. Layout elements will change the size according to the content. Set up a view of the size of Autosize attribute wrap_content roughly equivalent to set a Windows control for True.
