As Ian states in this Android Developers thread:

Anyhow, the deal is that layout of the contents of a window happens after all the elements are constructed and added to their parent views. It has to be this way, because until you know what components a View contains, and what they contain, and so on, there's no sensible way you can lay it out.

Bottom line, if you call getWidth() etc. in a constructor, it will return zero. The procedure is to create all your view elements in the constructor, then wait for your View's onSizeChanged() method to be called -- that's when you first find out your real size, so that's when you set up the sizes of your GUI elements.

Be aware too that onSizeChanged() is sometimes called with parameters of zero -- check for this case, and return immediately (so you don't get a divide by zero when calculating your layout, etc.). Some time later it will be called with the real values.

This problem has nothing to do with the linker, so modifying it's setting won't affect the outcome. You're getting this because I assume you're trying to target x86 but for one reason or another wxcode_msw28d_freechart.lib is being built as an x64 file.

Try looking at wxcode_msw28d_freechart.lib and whatever source code it derives from. Your problem is happening there. See if there are some special build steps that are using the wrong set of tools (x64 instead of x86).

Came across the same issue today. I simply reinstalled pip globally with sudo easy_install pip (OSX/ Max), then created my virtualenv again with sudo virtualenv nameOfVEnv. Then after activating the new virtualenv the pip command worked as expected.

I don't think I used sudo on the first virtualenv creation and that may have been the reason for not having access to pip from within the virtualenv, I was able to get access to pip2 before this fix though which was odd.

Do this to get the JSON

String json = EntityUtils.toString(response.getEntity());

More details here : get json from HttpResponse

I'm wondering why nobody just gave the most simple of answers:

val array: Array<Int> = [1, 2, 3]

As per one of the comments to my original answer, I realized this only works when used in annotations arguments (which was really unexpected for me).

Looks like Kotlin doesn't allow to create array literals outside annotations.

For instance, look at this code using @Option from args4j library:

    @Option(
        name = "-h",
        aliases = ["--help", "-?"],
        usage = "Show this help"
    )
    var help: Boolean = false

The option argument "aliases" is of type Array<String>

If you're doing programatic customisation, don't hard code the system font. Use UIFont systemFontOfSize:, UIFont boldSystemFontOfSize: and UIFont italicSystemFontOfSize (Apple documentation).

This has become especially relevant since iOS 7, which changed the system font to Helvetica Neue.

This has become super especially relevant since iOS 9, which changed the system font again to San Francisco.

You can also capitalize the first letter of the match using \I1 and \I2 etc instead of $1 and $2.

I was running in to the same issue, but have just managed a full uninstall by means of trusty old CMD:

D:\vs_ultimate.exe /uninstall /force

Where D: is the location of your installation media (mounted iso, etc).

You could also pass /passive (no user input required - just progress displayed) or /quiet to the above command line.

EDIT: Adding link below to MSDN article mentioning that this forcibly removes ALL installed components.

http://blogs.msdn.com/b/heaths/archive/2015/07/17/removing-visual-studio-components-left-behind-after-an-uninstall.aspx

Also, to ensure link rot doesn't invalidate this, adding brief text below from original article.

Starting with Visual Studio 2013, you can forcibly remove almost all components. A few core components – like the .NET Framework and VC runtimes – are left behind because of their ubiquity, though you can remove those separately from Programs and Features if you really want.

Warning: This will remove all components regardless of whether other products require them. This may cause other products to function incorrectly or not function at all.

Good luck!

EXECUTE IMMEDIATE 'insert into MY_TBL (Col) values(''ER0002'')'; worked for me. closing the varchar/string with two pairs of single quotes did the trick. Other option could be to use using keyword, EXECUTE IMMEDIATE 'insert into MY_TBL (Col) values(:text_string)' using 'ER0002'; Remember using keyword will not work, if you are using EXECUTE IMMEDIATE to execute DDL's with parameters, however, using quotes will work for DDL's.

UIImage *img = [UIImage imageNamed:@"anyImageName"];

imageNamed:
Returns the image object associated with the specified filename.

    + (UIImage *)imageNamed:(NSString *)name

Parameters
name
The name of the file. If this is the first time the image is being loaded, the method looks for an image with the specified name in the application’s main bundle.
Return Value
The image object for the specified file, or nil if the method could not find the specified image.

Discussion
This method looks in the system caches for an image object with the specified name and returns that object if it exists. If a matching image object is not already in the cache, this method loads the image data from the specified file, caches it, and then returns the resulting object.

Also worth noting you can use 'em' as well as 'px' - blogs and text based sites do it because then the browser makes layout decisions more relative to the text content.

On Wordpress twentysixteen I wanted my tagline to display on mobiles as well as desktops, so I put this in my child theme style.css

@media screen and (max-width:59em){
    p.site-description {
        display:    block;
    }
}

You can use Linq to cleverly initialize your list with a default value. (Similar to David B's answer.)

var defaultStrings = (new int[10]).Select(x => "my value").ToList();

Go one step farther and initialize each string with distinct values "string 1", "string 2", "string 3", etc:

int x = 1;
var numberedStrings = (new int[10]).Select(x => "string " + x++).ToList();

If performance is your main concern and you dont mind listening to different events, then this is the way to go for a stable sort:

public static void Sort<T>(this ObservableCollection<T> list) where T : IComparable<T>
{
    int i = 0;
    foreach (var item in list.OrderBy(x => x))
    {
        if (!item.Equals(list[i]))
        {
            list[i] = item;
        }

        i++;
    }
}

I am not sure if there is anything simpler and faster (at least theoretically), as far as stable sorts go. Doing a ToArray on the ordered list might make the enumeration faster but at worse space complexity. You could also do away with the Equals check to go even faster, but I guess reducing change notification is a welcome thing.

Also this doesn't break any bindings.

Mind you this raises a bunch of Replace events rather than Move (which is more expected for a Sort operation), and also the number of events raised will be most likely more when compared to other Move approaches in this thread but it is unlikely it matters for performance, I think.. Most UI elements must have implemented IList and doing a replace on ILists should be faster than Moves. But more changed events means more screen refreshes. You will have to test it out to see the implications.

For a Move answer, see this. Haven't seen a more correct implementation that works even when you have duplicates in the collection.

1) Go to C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A for VS2013

2) Copy the folders Include and Lib (you should check where are your folders in folder windows such as v7.1, v8, v6, etc.)

3) Paste them into C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC

I solved my problems like:

error lnk1104: cannot open file 'kernel32.lib'.
error c1083: Cannot open Windows.h

Thanks.

Jenkins 1.x

The following groovy snippet should pass the version (as you've already supplied), and store it in the job's variables as 'miniVersion'.

import hudson.model.*

def env = System.getenv()
def version = env['currentversion']
def m = version =~/\d{1,2}/
def minVerVal = m[0]+"."+m[1]

def pa = new ParametersAction([
  new StringParameterValue("miniVersion", minVerVal)
])

// add variable to current job
Thread.currentThread().executable.addAction(pa)

The variable will then be accessible from other build steps. e.g.

echo miniVersion=%miniVersion%

Outputs:

miniVersion=12.34

I believe you'll need to use the "System Groovy Script" (on the Master node only) as opposed to the "Groovy Plugin" - https://wiki.jenkins-ci.org/display/JENKINS/Groovy+plugin#Groovyplugin-GroovyScriptvsSystemGroovyScript

Jenkins 2.x

I believe the previous (Jenkins 1.x) behaviour stopped working because of this Security Advisory...

Solution (paraphrased from the Security Advisory)

It's possible to restore the previous behaviour by setting the system property hudson.model.ParametersAction.keepUndefinedParameters to true. This is potentially very unsafe and intended as a short-term workaround only.

java -Dhudson.model.ParametersAction.keepUndefinedParameters=true -jar jenkins.war

To allow specific, known safe parameter names to be passed to builds, set the system property hudson.model.ParametersAction.safeParameters to a comma-separated list of safe parameter names.

e.g.

java -Dhudson.model.ParametersAction.safeParameters=miniVersion,FOO,BAR -jar jenkins.war

you need to download and install jdk from here

This code work in IE7 and Chrome:

var hiddenInput = document.createElement("input");
    hiddenInput.setAttribute("id", "uniqueIdentifier");
    hiddenInput.setAttribute("type", "hidden");                     
    hiddenInput.setAttribute("value", 'ID');
    hiddenInput.setAttribute("class", "ListItem");

$('body').append(hiddenInput);

Maybe problem somewhere else ?

This was the best way for me. You can retrieve all existing files (be it symbolic links or normal):

os.path.lexists(path)

Return True if path refers to an existing path. Returns True for broken symbolic links. Equivalent to exists() on platforms lacking os.lstat().

New in version 2.4.

This problem may also occur when you are opening Android Studio and Eclipse at once. Try to close one of them and it might solve your issue.

add CSS or class to the input element which works in select and text tags like

style="pointer-events: none;background-color:#E9ECEF"

I think the best way is to store them in some yml file and then load that file using this command in intializer file

APP_CONFIG = YAML.load_file("#{Rails.root}/config/CONFIG.yml")[Rails.env].to_hash

you can easily access environment related config variables.

Your Yml file key value structure:

development:
  app_key: 'abc'
  app_secret: 'abc'

production:
  app_key: 'xyz'
  app_secret: 'ghq'

When you define a server in server view, then it will create you a server runtime library with server libs (including servlet api), that can be assigned to your project. However, then everybody that uses your project, need to create the same type of runtime in his/her eclipse workspace even for compiling.

If you directly download the servlet api jar, than it could lead to problems, since it will be included into the artifacts of your projects, but will be also present in servlet container.

In Maven it is much nicer, since you can define the servlet api interfaces as a "provided" dependency, that means it is present in the "to be production" environment.

SELECT CONVERT_TZ() will work for that.but its not working for me.

Why, what error do you get?

SELECT CONVERT_TZ(displaytime,'GMT','MET');

should work if your column type is timestamp, or date

http://dev.mysql.com/doc/refman/5.0/en/date-and-time-functions.html#function_convert-tz

Test how this works:

SELECT CONVERT_TZ(a_ad_display.displaytime,'+00:00','+04:00');

Check your timezone-table

SELECT * FROM mysql.time_zone;
SELECT * FROM mysql.time_zone_name;

http://dev.mysql.com/doc/refman/5.5/en/time-zone-support.html

If those tables are empty, you have not initialized your timezone tables. According to link above you can use mysql_tzinfo_to_sql program to load the Time Zone Tables. Please try this

shell> mysql_tzinfo_to_sql /usr/share/zoneinfo

or if not working read more: http://dev.mysql.com/doc/refman/5.5/en/mysql-tzinfo-to-sql.html

Actually a "Swifter" way to do it in swift is :

var lastIndex = NSIndexPath(forRow: self.messages.count - 1, inSection: 0)
self.messageTableView.scrollToRowAtIndexPath(lastIndex, atScrollPosition: UITableViewScrollPosition.Bottom, animated: true)

work Perfect for me.

you can put the first cell in your array to be empty({"","some","some",...}) and do nothing if the position is 0;

public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
    if(position>0) {
        label.setText(MainActivity.questions[position - 1]);
    }
}

• if you fill the array by xml file you can let the first item empty

This should work. You need to put in two slashes

str = str.replaceAll("(\\r\\n|\\n)", "<br />");

In this Reference, there is an example which shows

private final String REGEX = "\\d"; // a single digit

I have used two slashes in many of my projects and it seems to work fine!

You can do it in one line without nltk (python 3.x).

import string
string_text= string_text.translate(str.maketrans('','',string.punctuation))

I faced this problem where the following query doesn't work as expected:

select 1 where getdate()<>null

we expect it to show 1 because getdate() doesn't return null. I guess it has something to do with SQL failing to cast null as datetime and skipping the row! of course we know we should use IS or IS NOT keywords to compare a variable with null but when comparing two parameters it gets hard to handle the null situation. as a solution you can create your own compare function like the following:

CREATE FUNCTION [dbo].[fnCompareDates]
(
    @DateTime1 datetime,
    @DateTime2 datetime
)
RETURNS bit
AS
BEGIN
    if (@DateTime1 is null and @DateTime2 is null) return 1;
    if (@DateTime1 = @DateTime2) return 1;
    return 0
END

and re writing the query like:

select 1 where dbo.fnCompareDates(getdate(),null)=0

here's another solution for Python3:

import csv
with open(filename, "r") as csvfile:
    datareader = csv.reader(csvfile)
    count = 0
    for row in datareader:
        if row[3] in ("column header", criterion):
            doSomething(row)
            count += 1
        elif count > 2:
            break

here datareader is a generator function.

OpenCV Specific

Opencv supports filesystem, probably through its dependency Boost.

#include <opencv2/core/utils/filesystem.hpp>
cv::utils::fs::createDirectory(outputDir);

This is not a lambda function. It is a list comprehension.

Just change the order:

[ y for y in a if y not in b]

If you don't use a passphrase, then the private key is not encrypted with any symmetric cipher - it is output completely unprotected.

You can generate a keypair, supplying the password on the command-line using an invocation like (in this case, the password is foobar):

openssl genrsa -aes128 -passout pass:foobar 3072

However, note that this passphrase could be grabbed by any other process running on the machine at the time, since command-line arguments are generally visible to all processes.

A better alternative is to write the passphrase into a temporary file that is protected with file permissions, and specify that:

openssl genrsa -aes128 -passout file:passphrase.txt 3072

Or supply the passphrase on standard input:

openssl genrsa -aes128 -passout stdin 3072

You can also used a named pipe with the file: option, or a file descriptor.

To then obtain the matching public key, you need to use openssl rsa, supplying the same passphrase with the -passin parameter as was used to encrypt the private key:

openssl rsa -passin file:passphrase.txt -pubout

(This expects the encrypted private key on standard input - you can instead read it from a file using -in <file>).

Example of creating a 3072-bit private and public key pair in files, with the private key pair encrypted with password foobar:

openssl genrsa -aes128 -passout pass:foobar -out privkey.pem 3072
openssl rsa -in privkey.pem -passin pass:foobar -pubout -out privkey.pub

Simple:

delete myObj.test.key1;

@Someone Somewhere I used this to clear focus:

editText.clearFocus();

and it helps

Generally, EXC_BAD_INSTRUCTION means that there was an assertion failure in your code. A wild guess, your Screen.text is not an integer. Double check its type.

@ Robert: I have tried to adapt your code with a relative path, and created a batch file to run the VBS.

The VBS starts and closes but doesn't launch the macro... Any idea of where the issue could be?

ExcelMacroExample

Sub ExcelMacroExample() 

  Dim xlApp 
  Dim xlBook 

  Set xlApp = CreateObject("Excel.Application")
  Set objFSO = CreateObject("Scripting.FileSystemObject")
  strFilePath = objFSO.GetAbsolutePathName(".") 
  Set xlBook = xlApp.Workbooks.Open(strFilePath, "Excels\CLIENTES.xlsb") , 0, True) 
  xlApp.Run "open_form"


  Set xlBook = Nothing 
  Set xlApp = Nothing 

End Sub

I removed the "Application.Quit" because my macro is calling a userform taking care of it.

Cheers

EDIT

I have actually worked it out, just in case someone wants to run a userform "alike" a stand alone application:

Issues I was facing:

1 - I did not want to use the Workbook_Open Event as the excel is locked in read only. 2 - The batch command is limited that the fact that (to my knowledge) it cannot call the macro.

I first wrote a macro to launch my userform while hiding the application:

Sub open_form()
 Application.Visible = False
 frmAddClient.Show vbModeless
End Sub

I then created a vbs to launch this macro (doing it with a relative path has been tricky):

dim fso
dim curDir
dim WinScriptHost
set fso = CreateObject("Scripting.FileSystemObject")
curDir = fso.GetAbsolutePathName(".")
set fso = nothing

Set xlObj = CreateObject("Excel.application")
xlObj.Workbooks.Open curDir & "\Excels\CLIENTES.xlsb"
xlObj.Run "open_form"

And I finally did a batch file to execute the VBS...

@echo off
pushd %~dp0
cscript Add_Client.vbs

Note that I have also included the "Set back to visible" in my Userform_QueryClose:

Private Sub cmdClose_Click()
Unload Me
End Sub

Private Sub UserForm_QueryClose(Cancel As Integer, CloseMode As Integer)
    ThisWorkbook.Close SaveChanges:=True
    Application.Visible = True
    Application.Quit
End Sub

Anyway, thanks for your help, and I hope this will help if someone needs it

I had a very similar issue. I got the same error because the csv contained spaces in the header. My csv contained a header "Gender " and I had it listed as:

[['Gender']]

If it's easy enough for you to access your csv, you can use the excel formula trim() to clip any spaces of the cells.

or remove it like this

df.columns = df.columns.to_series().apply(lambda x: x.strip())

Something that I think should be commented here that worked for me:

Use :last-child multiple times in the places needed so that it always gets the last of the last.

Take this for example:

.page.one .page-container .comment:last-child {_x000D_
  color: red;_x000D_
}_x000D_
.page.two .page-container:last-child .comment:last-child {_x000D_
  color: blue;_x000D_
}

<p> When you use .comment:last-child </p>_x000D_
<p> you only get the last comment in both parents </p>_x000D_
_x000D_
<div class="page one">_x000D_
  <div class="page-container">_x000D_
    <p class="comment"> Something </p>_x000D_
    <p class="comment"> Something </p>_x000D_
  </div>_x000D_
_x000D_
  <div class="page-container">_x000D_
    <p class="comment"> Something </p>_x000D_
    <p class="comment"> Something </p>_x000D_
  </div>_x000D_
</div>_x000D_
_x000D_
<p> When you use .page-container:last-child .comment:last-child </p>_x000D_
<p> you get the last page-container's, last comment </p>_x000D_
_x000D_
<div class="page two">_x000D_
  <div class="page-container">_x000D_
    <p class="comment"> Something </p>_x000D_
    <p class="comment"> Something </p>_x000D_
  </div>_x000D_
_x000D_
  <div class="page-container">_x000D_
    <p class="comment"> Something </p>_x000D_
    <p class="comment"> Something </p>_x000D_
  </div>_x000D_

It looks like you are calling next even if the scanner no longer has a next element to provide... throwing the exception.

while(!file.next().equals(treasure)){
        file.next();
        }

Should be something like

boolean foundTreasure = false;

while(file.hasNext()){
     if(file.next().equals(treasure)){
          foundTreasure = true;
          break; // found treasure, if you need to use it, assign to variable beforehand
     }
}
    // out here, either we never found treasure at all, or the last element we looked as was treasure... act accordingly

If you just want to check if a string is all digits (without being within a particular number range) you can use:

string test = "123";
bool allDigits = test.All(char.IsDigit);

Config file changes are required to enable connections via localhost.

To connect through remote IPs, Login as a "root" user and run the below queries in mysql.

CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';

GRANT ALL PRIVILEGES ON *.* TO 'username'@'localhost' WITH GRANT OPTION;

CREATE USER 'username'@'%' IDENTIFIED BY 'password';

GRANT ALL PRIVILEGES ON *.* TO 'username'@'%' WITH GRANT OPTION;

FLUSH PRIVILEGES;

This will create a new user that is accessible on localhost as well as from remote IPs.

Also comment the below line from your my.cnf file located in /etc/mysql/my.cnf

bind-address = 127.0.0.1

Restart your mysql using

sudo service mysql restart

Now you should be able to connect remotely to your mysql.

Join on one-to-many relation in JPQL looks as follows:

select b.fname, b.lname from Users b JOIN b.groups c where c.groupName = :groupName 

When several properties are specified in select clause, result is returned as Object[]:

String fname = (String) temp[0];
String lname = (String) temp[1];

By the way, why your entities are named in plural form, it's confusing. If you want to have table names in plural, you may use @Table to specify the table name for the entity explicitly, so it doesn't interfere with reserved words:

@Entity @Table(name = "Users")     
public class User implements Serializable { ... } 

for LocalBroadcastManager

   Intent intent = new Intent("any.action.string");
   LocalBroadcastManager.getInstance(context).
                                sendBroadcast(intent);

and register in onResume

LocalBroadcastManager.getInstance(
                    ActivityName.this).registerReceiver(chatCountBroadcastReceiver, filter);

and Unregister it onStop

LocalBroadcastManager.getInstance(
                ActivityName.this).unregisterReceiver(chatCountBroadcastReceiver);

and recieve it ..

mBroadcastReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            Log.e("mBroadcastReceiver", "onReceive");
        }
    };

where IntentFilter is

 new IntentFilter("any.action.string")

DataType has a second constructor that takes a string. However, internally, this is actually the same as using the UIHint attribute.

Adding a new core DataType is not possible since the DataType enumeration is part of the .NET framework. The closest thing you can do is to create a new class that inherits from the DataTypeAttribute. Then you can add a new constructor with your own DataType enumeration.

public NewDataTypeAttribute(DataType dataType) : base(dataType)
 { }

public NewDataTypeAttribute(NewDataType newDataType) : base (newDataType.ToString();

You can also go through this link. But I will recommend you using Jquery for the same.

Reading these answers, I can see a lot relating to Spring version 4.x, I am using version 3.2.0 for various reasons. So things like json support straight from the content() is not possible.

I found that using MockMvcResultMatchers.jsonPath is really easy and works a treat. Here is an example testing a post method.

The bonus with this solution is that you're still matching on attributes, not relying on full json string comparisons.

(Using org.springframework.test.web.servlet.result.MockMvcResultMatchers)

String expectedData = "some value";
mockMvc.perform(post("/endPoint")
                .contentType(MediaType.APPLICATION_JSON)
                .content(mockRequestBodyAsString.getBytes()))
                .andExpect(status().isOk())
                .andExpect(MockMvcResultMatchers.jsonPath("$.data").value(expectedData));

The request body was just a json string, which you can easily load from a real json mock data file if you wanted, but I didnt include that here as it would have deviated from the question.

The actual json returned would have looked like this:

{
    "data":"some value"
}

Why are you combining GET and POST? Use one or the other.

$.ajax({
    type: 'post',
    data: {
        timestamp: timestamp,
        uid: uid
        ...
    }
});

php:

$uid =$_POST['uid'];

Or, just format your request properly (you're missing the ampersands for the get parameters).

url:"getdata.php?timestamp="+timestamp+"&uid="+id+"&uname="+name,

There can be two reasons for that error:

First

You are loding jQuery.DataTables.js before jquery.js so for that :-

You need to load jQuery.js before you load jQuery.DataTables.js

Second

You are using two versions of jQuery.js on the same page so for that :-

Try to use the higher version and make sure both links have same version of jQuery

make use of isspace function .

The C library function int isspace(int c) checks whether the passed character is white-space.

sample code:

    int main()
    {

       char var= ' ';

       if( isspace(var) )
       {
          printf("var1 = |%c| is a white-space character\n", var );
       }
/*instead you can easily compare character with ' '  
  */     
    }

Standard white-space characters are -

' '   (0x20)    space (SPC)
'\t'    (0x09)  horizontal tab (TAB)
'\n'    (0x0a)  newline (LF)
'\v'    (0x0b)  vertical tab (VT)
'\f'    (0x0c)  feed (FF)
'\r'    (0x0d)  carriage return (CR)

You are running into CORS issues.

There are several ways to fix/workaround this.

1. Turn off CORS. For example: how to turn off cors in chrome
2. Use a plugin for your browser
3. Use a proxy such as nginx. example of how to set up
4. Go through the necessary setup for your server. This is more a factor of the web server you have loaded on your EC2 instance (presuming this is what you mean by "Amazon web service"). For your specific server you can refer to the enable CORS website.

More verbosely, you are trying to access api.serverurl.com from localhost. This is the exact definition of cross domain request.

By either turning it off just to get your work done (OK, but poor security for you if you visit other sites and just kicks the can down the road) you can use a proxy which makes your browser think all requests come from local host when really you have local server that then calls the remote server.

so api.serverurl.com might become localhost:8000/api and your local nginx or other proxy will send to the correct destination.

Now by popular demand, 100% more CORS info....same great taste!

Bypassing CORS is exactly what is shown for those simply learning the front end. https://codecraft.tv/courses/angular/http/http-with-promises/

In Python 3, print is a function, you need to call it like print("hello world").

It is better to use implode for that purpose. Implode is easy and awesome:

    $array = ['name1', 'name2', 'name3'];
    $str = implode(', ', $array);

Output:

    name1, name2, name3

If the gem you are trying to install requires xml libraries, then try this:

sudo gem install -n /usr/local/bin  <gem_name> -- --use-system-libraries --with-xml2-include=/usr/include/libxml2 --with-xml2-lib=/usr/lib/

Specifically, I ran into a problem while installing the nokogiri gem v 1.6.8 on OS X El Capitan

and this finally worked for me:

sudo gem install -n /usr/local/bin  nokogiri -- --use-system-libraries --with-xml2-include=/usr/include/libxml2 --with-xml2-lib=/usr/lib/

To make sure you have libxml2 and libxslt installed, you can do:

brew install libxml2 libxslt
brew install libiconv

and then check to make sure you have xcode command line tools installed:

xcode-select --install 

should return this error:

xcode-select: error: command line tools are already installed, use "Software Update" to install updates

Here's a collection of scripts: http://webtecker.com/2008/03/26/collection-of-password-strength-scripts/

I think both of them rate the password and don't use jQuery... but I don't know if they have native support for disabling the form?

A slight variation on Richards answer but readTree can take a string so you can simplify it to:

ObjectMapper mapper = new ObjectMapper();
JsonNode actualObj = mapper.readTree("{\"k1\":\"v1\"}");

Add Regular to syntax and use gfn:

set gfn= Monospace\ Regular:h13

Dim obj : Set obj = CreateObject("Scripting.FileSystemObject")
Dim outFile : Set outFile = obj.CreateTextFile("in.txt")
Dim inFile: Set inFile = obj.OpenTextFile("out.txt")

' Read file
Dim strRetVal : strRetVal = inFile.ReadAll
inFile.Close

' Write file
outFile.write (strRetVal)
outFile.Close

I know this is an old post. However, I observed another instance where in the project already has Tomcat added but we still get this error. Did this to resolve that:
Alt + Enter
Project Facets
On the right, next to details, is another tab "Runtimes". The installed tomcat server will be listed there. Select it.
Save the configuration and DONE!

Hope this helps someone.

The Functional Java library has an array wrapper class that equips arrays with handy methods like concatenation.

import static fj.data.Array.array;

...and then

Array<String> both = array(first).append(array(second));

To get the unwrapped array back out, call

String[] s = both.array();

Ok, this is a simple class to be used for simple simple timing of your functions. There is an example below it.

public class Stopwatch {
    static long startTime;
    static long splitTime;
    static long endTime;

    public Stopwatch() {
        start();
    }

    public void start() {
        startTime = System.currentTimeMillis();
        splitTime = System.currentTimeMillis();
        endTime = System.currentTimeMillis();
    }

    public void split() {
        split("");
    }

    public void split(String tag) {
        endTime = System.currentTimeMillis();
        System.out.println("Split time for [" + tag + "]: " + (endTime - splitTime) + " ms");
        splitTime = endTime;
    }

    public void end() {
        end("");
    }
    public void end(String tag) {
        endTime = System.currentTimeMillis();
        System.out.println("Final time for [" + tag + "]: " + (endTime - startTime) + " ms");
    }
}

Sample of use:

public static Schedule getSchedule(Activity activity_context) {
        String scheduleJson = null;
        Schedule schedule = null;
/*->*/  Stopwatch stopwatch = new Stopwatch();

        InputStream scheduleJsonInputStream = activity_context.getResources().openRawResource(R.raw.skating_times);
/*->*/  stopwatch.split("open raw resource");

        scheduleJson = FileToString.convertStreamToString(scheduleJsonInputStream);
/*->*/  stopwatch.split("file to string");

        schedule = new Gson().fromJson(scheduleJson, Schedule.class);
/*->*/  stopwatch.split("parse Json");
/*->*/  stopwatch.end("Method getSchedule"); 
    return schedule;
}

Sample of console output:

Split time for [file to string]: 672 ms
Split time for [parse Json]: 893 ms
Final time for [get Schedule]: 1565 ms

I suspect one of your scripts includes a source map URL. (Minified jQuery contains a reference to a source map, for example.)

When you open the Chrome developer tools, Chrome will try to fetch the source map from the URL to aid debugging. However, the source map does not actually exist on your server, but you are instead sent a regular 404 page containing HTML.

What you can do and what you should do are different matters.

If the list is very short, or you are only ever going to call find once then use the linear approach above.

However linear-search is one of the biggest evils I find in slow code, and consider using an ordered collection (set or multiset if you allow duplicates). If you need to keep a list for other reasons eg using an LRU technique or you need to maintain the insertion order or some other order, create an index for it. You can actually do that using a std::set of the list iterators (or multiset) although you need to maintain this any time your list is modified.

CMD:

reg query "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment"
reg query HKEY_CURRENT_USER\Environment

PowerShell:

Get-Item "HKLM:\SYSTEM\CurrentControlSet\Control\Session Manager\Environment"
Get-Item HKCU:\Environment

Powershell/.NET: (see EnvironmentVariableTarget Enum)

[System.Environment]::GetEnvironmentVariables([System.EnvironmentVariableTarget]::Machine)
[System.Environment]::GetEnvironmentVariables([System.EnvironmentVariableTarget]::User)

I had log4j.properties in the correct place in the classpath and still got this warning with anything that used it directly. Code using log4j through commons-logging seemed to be fine for some reason.

If you have:

log4j.rootLogger=WARN

Change it to:

log4j.rootLogger=WARN, console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.conversionPattern=%5p [%t] (%F:%L) - %m%n

According to http://logging.apache.org/log4j/1.2/manual.html:

The root logger is anonymous but can be accessed with the Logger.getRootLogger() method. There is no default appender attached to root.

What this means is that you need to specify some appender, any appender, to the root logger to get logging to happen.

Adding that console appender to the rootLogger gets this complaint to disappear.

Firstly said, I try to force all my users to use Chrome when printing because other browsers create different layouts.

An answer from this question recommends:

@page {
  size: 210mm 297mm; 
  /* Chrome sets own margins, we change these printer settings */
  margin: 27mm 16mm 27mm 16mm; 
}

However, I ended up using this CSS for all my pages to be printed:

@media print 
{
    @page {
      size: A4; /* DIN A4 standard, Europe */
      margin:0;
    }
    html, body {
        width: 210mm;
        /* height: 297mm; */
        height: 282mm;
        font-size: 11px;
        background: #FFF;
        overflow:visible;
    }
    body {
        padding-top:15mm;
    }
}

Special case: Long Tables

When I needed to print a table over several pages, the margin:0 with the @page was leading to bleeding edges:

I could solve this thanks to this answer with:

table { page-break-inside:auto }
tr    { page-break-inside:avoid; page-break-after:auto }
thead { display:table-header-group; }
tfoot { display:table-footer-group; }

Plus setting the top-bottom-margins for @page:

@page { 
    size: auto;
    margin: 20mm 0 10mm 0;
}
body {
    margin:0;
    padding:0;
}

Result:

I would rather prefer a solution that is concise and works with all browser. For now, I hope the information above can help some developers with similar issues.

Hotswap Agent is an extension to DCEVM which supports many Java frameworks (reload Spring bean definition, Hibernate entity mapping, logger level setup, ...).

There is also lot of documentation how to setup DCEVM and compiled binaries for Java 1.7.

In addition to FLAG_ACTIVITY_CLEAR_TOP, you may try adding Intent.FLAG_ACTIVITY_SINGLE_TOP as well:

intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP); intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

Added some more logic to solution provided by @Andrew Burgess. Here is the full solution:

Created a action filter to get errors for ajax request:

public class ValidateAjaxAttribute : ActionFilterAttribute
    {
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            if (!filterContext.HttpContext.Request.IsAjaxRequest())
                return;

            var modelState = filterContext.Controller.ViewData.ModelState;
            if (!modelState.IsValid)
            {
                var errorModel =
                        from x in modelState.Keys
                        where modelState[x].Errors.Count > 0
                        select new
                        {
                            key = x,
                            errors = modelState[x].Errors.
                                                          Select(y => y.ErrorMessage).
                                                          ToArray()
                        };
                filterContext.Result = new JsonResult()
                {
                    Data = errorModel
                };
                filterContext.HttpContext.Response.StatusCode =
                                                      (int)HttpStatusCode.BadRequest;
            }
        }
    }

Added the filter to my controller method as:

[HttpPost]
// this line is important
[ValidateAjax]
public ActionResult AddUpdateData(MyModel model)
{
    return Json(new { status = (result == 1 ? true : false), message = message }, JsonRequestBehavior.AllowGet);
}

Added a common script for jquery validation:

function onAjaxFormError(data) {
    var form = this;
    var errorResponse = data.responseJSON;
    $.each(errorResponse, function (index, value) {
        // Element highlight
        var element = $(form).find('#' + value.key);
        element = element[0];
        highLightError(element, 'input-validation-error');

        // Error message
        var validationMessageElement = $('span[data-valmsg-for="' + value.key + '"]');
        validationMessageElement.removeClass('field-validation-valid');
        validationMessageElement.addClass('field-validation-error');
        validationMessageElement.text(value.errors[0]);
    });
}

$.validator.setDefaults({
            ignore: [],
            highlight: highLightError,
            unhighlight: unhighlightError
        });

var highLightError = function(element, errorClass) {
    element = $(element);
    element.addClass(errorClass);
}

var unhighLightError = function(element, errorClass) {
    element = $(element);
    element.removeClass(errorClass);
}

Finally added the error javascript method to my Ajax Begin form:

@model My.Model.MyModel
@using (Ajax.BeginForm("AddUpdateData", "Home", new AjaxOptions { HttpMethod = "POST", OnFailure="onAjaxFormError" }))
{
}

Ofri's answer gives you everything you asked for. But.. if you don't want to remember the command you can add this to your ~/.bashrc (or equivalent):

csview()
{
local file="$1"
sed "s/,/\t/g" "$file" | less -S
}

This is exactly the same as Ofri's answer except I have wrapped it in a shell function and am using the less -S option to stop the wrapping of lines (makes less behaves more like a office/oocalc).

Open a new shell (or type source ~/.bashrc in your current shell) and run the command using:

csview <filename>

In my case there was a need for:

@Injectable({
    providedIn: 'root'  // <- ADD THIS
})
export class FooService { ...

instead of just:

@Injectable()
export class FooService { ...

First the good news. This code does what you want (please note the "line numbers")

Sub a()
 10:    On Error GoTo ErrorHandler
 20:    DivisionByZero = 1 / 0
 30:    Exit Sub
 ErrorHandler:
 41: If Err.Number <> 0 Then
 42:    Msg = "Error # " & Str(Err.Number) & " was generated by " _
         & Err.Source & Chr(13) & "Error Line: " & Erl & Chr(13) & Err.Description
 43:    MsgBox Msg, , "Error", Err.HelpFile, Err.HelpContext
 44:    End If
 50:    Resume Next
 60: End Sub

When it runs, the expected MsgBox is shown:

And now the bad news:
Line numbers are a residue of old versions of Basic. The programming environment usually took charge of inserting and updating them. In VBA and other "modern" versions, this functionality is lost.

However, Here there are several alternatives for "automatically" add line numbers, saving you the tedious task of typing them ... but all of them seem more or less cumbersome ... or commercial.

HTH!

I have a simple Location class that I use to handle all of my marker-related things. I'll paste my code below for you to take a gander at.

The last line(s) is what actually creates the marker objects. It loops through some JSON of my locations, which look something like this:

{"locationID":"98","name":"Bergqvist Järn","note":null,"type":"retail","address":"Smidesvägen 3","zipcode":"69633","city":"Askersund","country":"Sverige","phone":"0583-120 35","fax":null,"email":null,"url":"www.bergqvist-jb.com","lat":"58.891079","lng":"14.917371","contact":null,"rating":"0","distance":"45.666885421019"}

Here is the code:

If you look at the target() method in my Location class, you'll see that I keep references to the infowindow's and can simply open() and close() them because of a reference.

See a live demo: http://ww1.arbesko.com/en/locator/ (type in a Swedish city, like stockholm, and hit enter)

var Location = function() {
    var self = this,
        args = arguments;

    self.init.apply(self, args);
};

Location.prototype = {

IN xampp just export the required table as a .sql file and then import it to the required

Another option is to use apt-file (i.e. apt-file search makeinfo). It may or may not be installed in your distro by default, but it is a great tool for determining what package a file belongs to.

I just had the same error (with PHP 5.2.6), and all I had to do is enable the MySQL-specific PDO driver:

TL;DR

In your php.ini file, you should have the following line (uncommented):

• extension=php_pdo_mysql.dll on Windows
• extension=php_pdo_mysql.so on Linux/Mac

Longer explanation:

1. open php.ini in a text editor

   • _{e.g. its default path on Windows: C:\Program Files (x86)\PHP\v5.X\php.ini (substitute v5.x with the version you installed) or C:\Windows\php.ini, etc.}
   • _{or on Linux: /etc/php5/apache2/php.ini (e.g. this is the path on Ubuntu) or /etc/php5/cli/php.ini, /etc/php5/cgi/php.ini, etc.}
   • _{or you can get to know where it is like this:}
     • _{php --ini | find /i "Loaded" in Windows command prompt OR}
     • _{php --ini | grep "Loaded" in Linux/Mac terminal}
     • _{using phpinfo(), and looking for the line "Loaded Configuration File"}

2. and remove the semicolon from the beginning of the following line (to uncomment it):

   • ;extension=php_pdo_mysql.dll on Windows
     • OR ;extension=php_pdo_mysql.so on Linux/Mac
   • of course, if this line doesn't exist, you should paste it
   • so as a result the expected line would look like this in php.ini:
     • extension=php_pdo_mysql.dll on Windows
     • OR extension=php_pdo_mysql.so on Linux/Mac

3. You may need to restart your web server.

That solved my problem.

You can do this like that:

x = list(set(x))

Example: if you do something like that:

x = [1,2,3,4,5,6,7,8,9,10,2,1,6,31,20]
x = list(set(x))
x

you will see the following result:

[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 31]

There is only one thing you should think of: the resulting list will not be ordered as the original one (will lose the order in the process).

You need to call the AddAddress method once for every recipient. Like so:

$mail->AddAddress('[email protected]', 'Person One');
$mail->AddAddress('[email protected]', 'Person Two');
// ..

Better yet, add them as Carbon Copy recipients.

$mail->AddCC('[email protected]', 'Person One');
$mail->AddCC('[email protected]', 'Person Two');
// ..

To make things easy, you should loop through an array to do this.

$recipients = array(
   '[email protected]' => 'Person One',
   '[email protected]' => 'Person Two',
   // ..
);
foreach($recipients as $email => $name)
{
   $mail->AddCC($email, $name);
}

Seriously? You folks have never used

If you are looking for something very accurate, you need to use some better tool than tf-idf. Universal sentence encoder is one of the most accurate ones to find the similarity between any two pieces of text. Google provided pretrained models that you can use for your own application without a need to train from scratch anything. First, you have to install tensorflow and tensorflow-hub:

    pip install tensorflow
    pip install tensorflow_hub

The code below lets you convert any text to a fixed length vector representation and then you can use the dot product to find out the similarity between them

import tensorflow_hub as hub
module_url = "https://tfhub.dev/google/universal-sentence-encoder/1?tf-hub-format=compressed"

# Import the Universal Sentence Encoder's TF Hub module
embed = hub.Module(module_url)

# sample text
messages = [
# Smartphones
"My phone is not good.",
"Your cellphone looks great.",

# Weather
"Will it snow tomorrow?",
"Recently a lot of hurricanes have hit the US",

# Food and health
"An apple a day, keeps the doctors away",
"Eating strawberries is healthy",
]

similarity_input_placeholder = tf.placeholder(tf.string, shape=(None))
similarity_message_encodings = embed(similarity_input_placeholder)
with tf.Session() as session:
    session.run(tf.global_variables_initializer())
    session.run(tf.tables_initializer())
    message_embeddings_ = session.run(similarity_message_encodings, feed_dict={similarity_input_placeholder: messages})

    corr = np.inner(message_embeddings_, message_embeddings_)
    print(corr)
    heatmap(messages, messages, corr)

and the code for plotting:

def heatmap(x_labels, y_labels, values):
    fig, ax = plt.subplots()
    im = ax.imshow(values)

    # We want to show all ticks...
    ax.set_xticks(np.arange(len(x_labels)))
    ax.set_yticks(np.arange(len(y_labels)))
    # ... and label them with the respective list entries
    ax.set_xticklabels(x_labels)
    ax.set_yticklabels(y_labels)

    # Rotate the tick labels and set their alignment.
    plt.setp(ax.get_xticklabels(), rotation=45, ha="right", fontsize=10,
         rotation_mode="anchor")

    # Loop over data dimensions and create text annotations.
    for i in range(len(y_labels)):
        for j in range(len(x_labels)):
            text = ax.text(j, i, "%.2f"%values[i, j],
                           ha="center", va="center", color="w", 
fontsize=6)

    fig.tight_layout()
    plt.show()

the result would be:

as you can see the most similarity is between texts with themselves and then with their close texts in meaning.

IMPORTANT: the first time you run the code it will be slow because it needs to download the model. if you want to prevent it from downloading the model again and use the local model you have to create a folder for cache and add it to the environment variable and then after the first time running use that path:

tf_hub_cache_dir = "universal_encoder_cached/"
os.environ["TFHUB_CACHE_DIR"] = tf_hub_cache_dir

# pointing to the folder inside cache dir, it will be unique on your system
module_url = tf_hub_cache_dir+"/d8fbeb5c580e50f975ef73e80bebba9654228449/"
embed = hub.Module(module_url)

In Java getters and setters are completely ordinary functions. The only thing that makes them getters or setters is convention. A getter for foo is called getFoo and the setter is called setFoo. In the case of a boolean, the getter is called isFoo. They also must have a specific declaration as shown in this example of a getter and setter for 'name':

class Dummy
{
    private String name;

    public Dummy() {}

    public Dummy(String name) {
        this.name = name;
    }

    public String getName() {
        return this.name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

The reason for using getters and setters instead of making your members public is that it makes it possible to change the implementation without changing the interface. Also, many tools and toolkits that use reflection to examine objects only accept objects that have getters and setters. JavaBeans for example must have getters and setters as well as some other requirements.

If at all anyone is looking to convert data in 1 variable that lies in 2 or 3 different lines like below

'Data1

Data2'

And you want to display data as 'Data1 Data2' then use below

select TRANSLATE ('Data1

Data2', ''||CHR(10), ' ') from dual;

it took me hrs to get the right output. Thanks to me I just saved you 1 or 2 hrs :)

The error occur because the mysql server is not starting on your computer. You should start it manually. Do following steps:

1. Download and install wamp server according to your bit version(32bit or 64bit) in your computer(http://wampserver-64bit.en.softonic.com/) this link allows you to download wamp server for 64bit.

2. As soon as you install it you can double click and run it..(you can see a icon in the right hand of the taskbar.It may be hidden .so you can click the arrow which show you the hide apps runing).So click the icon and go to Mysql

3. Then go to Service and there you can find Start/Resume Services click on it..

4. And now it is done.Open mysql workbench and see.It will work..

Its actually enough to add -m to startup parameters on Sql Server Configuration Manager, restart service, go to ssms an add checkbox sysadmin on your account, then remove -m restart again and use as usual.

Database Engine Service Startup Options

-m Starts an instance of SQL Server in single-user mode.

A lazy unmount will do the job for you.

umount -l <mount path>

A simple solution is to set an option with a blank value "" I found this eliminates the extra undefined option.

Try authbind:

http://manpages.ubuntu.com/manpages/hardy/man1/authbind.1.html

After installing, you can add a file with the name of the port number you want to use in the following folder: /etc/authbind/byport/

Give it 500 permissions using chmod and change the ownership to the user you want to run the program under.

After that, do "authbind node ..." as that user in your project.

The docs give a pretty good explanation of the difference between apply() and commit():

Unlike commit(), which writes its preferences out to persistent storage synchronously, apply() commits its changes to the in-memory SharedPreferences immediately but starts an asynchronous commit to disk and you won't be notified of any failures. If another editor on this SharedPreferences does a regular commit() while a apply() is still outstanding, the commit() will block until all async commits are completed as well as the commit itself. As SharedPreferences instances are singletons within a process, it's safe to replace any instance of commit() with apply() if you were already ignoring the return value.

Right click the project and give maven build,maven clean,maven generate resource and maven install.The jar file will automatically generate.

LIBS += C:\Program Files\OpenCV\lib

won't work because you're using white-spaces in Program Files. In this case you have to add quotes, so the result will look like this: LIBS += "C:\Program Files\OpenCV\lib". I recommend placing libraries in non white-space locations ;-)

Just for documentation purposes, here's what I've done for the fastest/most responsive click on desktop/tap on mobile solution that I could think of:

I replaced jQuery's on function with a modified one that, whenever the browser supports touch events, replaced all my click events with touchstart.

$.fn.extend({ _on: (function(){ return $.fn.on; })() });
$.fn.extend({
    on: (function(){
        var isTouchSupported = 'ontouchstart' in window || window.DocumentTouch && document instanceof DocumentTouch;
        return function( types, selector, data, fn, one ) {
            if (typeof types == 'string' && isTouchSupported && !(types.match(/touch/gi))) types = types.replace(/click/gi, 'touchstart');
            return this._on( types, selector, data, fn);
        };
    }()),
});

Usage than would be the exact same as before, like:

$('#my-button').on('click', function(){ /* ... */ });

But it would use touchstart when available, click when not. No delays of any kind needed :D

Don’t Repeat Your CSS

 a.abc, a.xyz{
    margin-left:20px;
 }

OR

 a{
    margin-left:20px;
 }

Press Ctrl+shift+L and type your string

If you absolutely must use HTML to give your text color, you have to use the (deprecated) <font>-tag:

<h2><font color="#006699">Process Report</font></h2>

But otherwise, I strongly recommend you to do as rekire said: use CSS.

Welcome to hell.

You can just pass a datetime64 object to pandas.Timestamp:

In [16]: Timestamp(numpy.datetime64('2012-05-01T01:00:00.000000'))
Out[16]: <Timestamp: 2012-05-01 01:00:00>

I noticed that this doesn't work right though in NumPy 1.6.1:

numpy.datetime64('2012-05-01T01:00:00.000000+0100')

Also, pandas.to_datetime can be used (this is off of the dev version, haven't checked v0.9.1):

In [24]: pandas.to_datetime('2012-05-01T01:00:00.000000+0100')
Out[24]: datetime.datetime(2012, 5, 1, 1, 0, tzinfo=tzoffset(None, 3600))

Unfortunately .mov files are not supported with html5 video playback. You can see what filetypes are supported here:

https://developer.mozilla.org/en-US/docs/Web/HTML/Supported_media_formats

If you need to be able to play these formats with your html5 video player, you'll need to first convert your videofile--perhaps with something like this:

https://www.npmjs.com/package/html5-media-converter

If you want to further automate this, because you are checking your module into version control, and don't want to rely upon devs remembering to npm link, you can add this to your package.json "scripts" section:

"scripts": {
    "postinstall": "npm link ../somelocallib",
    "postupdate": "npm link ../somelocallib"
  }

This feels beyond hacky, but it seems to "work". Got the tip from this npm issue: https://github.com/npm/npm/issues/1558#issuecomment-12444454

To enable intl extension follow the instructions below.

You need enable extension by uncommenting the following line extension=php_intl.dll in the C:\xampp\php\php.ini file. Once you uncomment the extension=php_intl.dll, then you must restart apache server using XAMPP control panel.

//about line 998
;extension=php_intl.dll 
change as
extension=php_intl.dll

(Note: php.ini file mostly in the following directory C:\xampp\php)

Restart xampp

It will return an empty enumerable. It wont be null. You can sleep sound :)

Another way would be to open terminal ctrl+` execute node. Now you have a node REPL active. You can now send your file or selected text to terminal. In order to do that open VSCode command pallete (F1 or ctrl+shift+p) and execute >run selected text in active terminal or >run active file in active terminal.

If you need a clean REPL before executing your code you will have to restart the node REPL. This is done when in the Terminal with the node REPL ctrl+c ctrl+c to exit it and typing node to start new.

You could probably key bind the command pallete commands to whatever key you wish.

PS: node should be installed and in your path

Bytecode representation

Java's null has direct JVM support: three instructions are used to implement it:

• aconst_null: e.g. to set a variable to null as in Object o = null;
• ifnull and ifnonnull: e.g. to compare an object to null as in if (o == null)

Chapter 6 "The Java Virtual Machine Instruction Set " then mentions the effects of null on other instructions: it throws a NullPointerException for many of them.

2.4. "Reference Types and Values" also mentions null in generic terms:

A reference value may also be the special null reference, a reference to no object, which will be denoted here by null. The null reference initially has no run-time type, but may be cast to any type. The default value of a reference type is null.

You can get some inspiration by reading an entrypoint.sh script written by the contributors from MySQL that checks whether the specified variables were set.

As the script shows, you can pipe them with -a, e.g.:

if [ -z "$MYSQL_ROOT_PASSWORD" -a -z "$MYSQL_ALLOW_EMPTY_PASSWORD" -a -z "$MYSQL_RANDOM_ROOT_PASSWORD" ]; then
    ...
fi

How do you want things to behave?

If you want arrays with no elements to be treated the same as unassigned arrays, use:

[array]$foo = @() #example where we'd want TRUE to be returned
@($foo).Count -eq 0

If you want a blank array to be seen as having a value (albeit an empty one), use:

[array]$foo = @() #example where we'd want FALSE to be returned
$foo.PSObject -eq $null

If you want an array which is populated with only null values to be treated as null:

[array]$foo = $null,$null
@($foo | ?{$_.PSObject}).Count -eq 0 

NB: In the above I use $_.PSObject over $_ to avoid [bool]$false, [int]0, [string]'', etc from being filtered out; since here we're focussed solely on nulls.

In my programs, by convention, this is what the pre-existing $REPLY variable is for, which read uses for that exact purpose.

function getSomeString {
  REPLY="tadaa"
}

getSomeString
echo $REPLY

This echoes

tadaa

But to avoid conflicts, any other global variable will do.

declare result

function getSomeString {
  result="tadaa"
}

getSomeString
echo $result

If that isn’t enough, I recommend Markarian451’s solution.

You can modify your REST project, so as to produce the needed static documents (html, pdf etc) upon building the project.

If you have a Java Maven project you can use the pom snippet below. It uses a series of plugins to generate a pdf and an html documentation (of the project's REST resources).

1. rest-api -> swagger.json : swagger-maven-plugin
2. swagger.json -> Asciidoc : swagger2markup-maven-plugin
3. Asciidoc -> PDF : asciidoctor-maven-plugin

Please be aware that the order of execution matters, since the output of one plugin, becomes the input to the next:

The asciidoctor plugin assumes the existence of an .adoc file to work on. You can create one that simply collects the ones that were created by the swagger2markup plugin:

include::{generated}/overview.adoc[]
include::{generated}/paths.adoc[]
include::{generated}/definitions.adoc[]

If you want your generated html document to become part of your war file you have to make sure that it is present on the top level - static files in the WEB-INF folder will not be served. You can do this in the maven-war-plugin:

<plugin>
    <artifactId>maven-war-plugin</artifactId>
    <configuration>
        <warSourceDirectory>WebContent</warSourceDirectory>
        <failOnMissingWebXml>false</failOnMissingWebXml>
        <webResources>
            <resource>
                <directory>${generated.html.directory}</directory>
            <!-- Add swagger.pdf to WAR file, so as to make it available as static content. -->
            </resource>
            <resource>
                <directory>${generated.pdf.directory}</directory>
            <!-- Add swagger.html to WAR file, so as to make it available as static content. -->
            </resource>
        </webResources>
    </configuration>
</plugin>

The war plugin works on the generated documentation - as such, you must make sure that those plugins have been executed in an earlier phase.

The built-in timeit module works best from the IPython command line.

To time functions from within a module:

from timeit import default_timer as timer
import sys

def timefunc(func, *args, **kwargs):
    """Time a function. 

    args:
        iterations=3

    Usage example:
        timeit(myfunc, 1, b=2)
    """
    try:
        iterations = kwargs.pop('iterations')
    except KeyError:
        iterations = 3
    elapsed = sys.maxsize
    for _ in range(iterations):
        start = timer()
        result = func(*args, **kwargs)
        elapsed = min(timer() - start, elapsed)
    print(('Best of {} {}(): {:.9f}'.format(iterations, func.__name__, elapsed)))
    return result

re.Match objects have a number of methods to help you with this:

>>> m = re.search("is", String)
>>> m.span()
(2, 4)
>>> m.start()
2
>>> m.end()
4

This is an interesting old question. I'm adding an answer because nobody noticed a couple of things with the original question.

Which is faster: Convert.ToDouble or Double.TryParse? Which is safer: Convert.ToDouble or Double.TryParse?

I'm going to answer both these questions (I'll update the answer later), in detail, but first:

For safety, the thing every programmer missed in this question is the line (emphasis mine):

It adds only data that are numbers with a few digits (1000 1000,2 1000,34 - comma is a delimiter in Russian standards).

Followed by this code example:

Convert.ToDouble(regionData, CultureInfo.CurrentCulture);

What's interesting here is that if the spreadsheets are in Russian number format but Excel has not correctly typed the cell fields, what is the correct interpretation of the values coming in from Excel?

Here is another interesting thing about the two examples, regarding speed:

catch (InvalidCastException)
{
    // is not a number
}

This is likely going to generate MSIL that looks like this:

catch [mscorlib]System.InvalidCastException 
{
  IL_0023:  stloc.0
  IL_0024:  nop
  IL_0025:  ldloc.0
  IL_0026:  nop
  IL_002b:  nop
  IL_002c:  nop
  IL_002d:  leave.s    IL_002f
}  // end handler
IL_002f: nop
IL_0030: return

In this sense, we can probably compare the total number of MSIL instructions carried out by each program - more on that later as I update this post.

I believe code should be Correct, Clear, and Fast... In that order!

Small but a effective solution. In my case i updated to my xcode to 9.2 version and simulators disappeared.

I found this solution and it worked for me and for others also.

**

Just quit your xcode and restart again. You will have simulators.

This code will help a lot

function isObject(data){
    var tb = document.createElement("table");

    if(data !=null) {
        var keyOfobj = Object.keys(data);
        var ValOfObj = Object.values(data);

        for (var i = 0; i < keyOfobj.length; i++) {
            var tr = document.createElement('tr');
            var td = document.createElement('td');
            var key = document.createTextNode(keyOfobj[i]);

            td.appendChild(key);
            tr.appendChild(td);
            tb.appendChild(tr);

            if(typeof(ValOfObj[i]) == "object") {

                if(ValOfObj[i] !=null) {
                    tr.setAttribute("style","font-weight: bold");   
                    isObject(ValOfObj[i]);
                } else {
                    var td = document.createElement('td');
                    var value = document.createTextNode(ValOfObj[i]);

                    td.appendChild(value);
                    tr.appendChild(td);
                    tb.appendChild(tr);
                }
            } else {
                var td = document.createElement('td');
                var value = document.createTextNode(ValOfObj[i]);

                td.appendChild(value);
                tr.appendChild(td);
                tb.appendChild(tr);
            }
        }
    }
}

I personally use interfaces for my models, There hoewver are 3 schools regarding this question, and choosing one is most often based on your requirements:

1- Interfaces:

interface is a virtual structure that only exists within the context of TypeScript. The TypeScript compiler uses interfaces solely for type-checking purposes. Once your code is transpiled to its target language, it will be stripped from its interfaces - JavaScript isn’t typed.

interface User {
 id: number;
 username: string;
}
// inheritance
interface UserDetails extends User {
 birthdate: Date;
 biography?: string;  // use the '?' annotation to mark this property as optionnal
}

Mapping server response to an interface is straight forward if you are using HttpClient from HttpClientModule if you are using Angular 4.3.x and above.

getUsers() :Observable<User[]> {
 return this.http.get<User[]>(url); // no need for '.map((res: Response) => res.json())' 
}

when to use interfaces:

• You only need the definition for the server data without introducing additional overhead for the final output.
• You only need to transmit data without any behaviors or logic (constructor initialization, methods)
• You do not instantiate/create objects from your interface very often
  • Using simple object-literal notationlet instance: FooInterface = { ... };, you risk having semi-instances all over the place.
  • That doesn't enforce the constraints given by a class ( constructor or initialization logic, validation, encapsulation of private fields...Etc)
• You need to define contracts/configurations for your systems (global configurations)

2- Classes:

A class defines the blueprints of an object. They express the logic, methods, and properties these objects will inherit.

class User {
 id: number;
 username: string;
 constructor(id :number, username: string)  {
  this.id = id;
  this.username = username.replace(/^\s+|\s+$/g, ''); // trim whitespaces and new lines
 }
}
// inheritance
class UserDetails extends User {
 birthdate: Date;
 biography?: string;  
 constructor(id :number, username: string, birthdate:Date, biography? :string )  {
   super(id,username);
  this.birthdate = ...;
 }
}

when to use classes:

• You instantiate your class and change the instances state over time.
• Instances of your class will need methods to query or mutate its state
• When you want to associate behaviors with data more closely;
• You enforce constraints on the creation of your instaces.
• If you only write a bunch of properties assignments in your class, you might consider using a type instead.

2- Types:

With the latest versions of typescript, interfaces and types becoming more similar. types do not express logic or state inside your application. It is best to use types when you want to describe some form of information. They can describe varying shapes of data, ranging from simple constructs like strings, arrays, and objects. Like interfaces, types are only virtual structures that don't transpile to any javascript, they just help the compiler making our life easier.

type User = {
 id: number;
 username: string;
}
// inheritance
type UserDetails = User & {
  birthDate :Date;
  biography?:string;
}

when to use types:

• pass it around as concise function parameters
• describe a class constructor parameters
• document small or medium objects coming in or out from an API.
• they don't carry state nor behavior

Please don't try and roll your own with a TreeView/DirectoryInfo class. For one thing there are many nice features you get for free (icons/right-click/networks) by using SHBrowseForFolder. For another there are a edge cases/catches you will likely not be aware of.

Note that this most often occurs when the content has been "double encoded", meaning the encoding algorithm has accidentally been called twice.

The first call would encode the "text2" value:

FROM: Heute startet unsere Rundreise "Example text". Jeden Tag wird ein neues Reiseziel angesteuert bis wir.

TO: Heute startet unsere Rundreise \"Example text\". Jeden Tag wird ein neues Reiseziel angesteuert bis wir.

A second encoding then converts it again, escaping the already escaped characters:

FROM: Heute startet unsere Rundreise \"Example text\". Jeden Tag wird ein neues Reiseziel angesteuert bis wir.

TO: Heute startet unsere Rundreise \\\"Example text\\\". Jeden Tag wird ein neues Reiseziel angesteuert bis wir.

So, if you are responsible for the implementation of the server here, check to make sure there aren't two steps trying to encode the same content.

Using Apache ArrayUtils downloadable at this link you can easy use the method

subarray(boolean[] array, int startIndexInclusive, int endIndexExclusive) 

"boolean" is only an example, there are methods for all primitives java types

You can return json in PHP this way:

header('Content-Type: application/json');
echo json_encode(array('foo' => 'bar'));
exit;

It's because you have turned on USB debugging in Developer Options. You can create a bug report by holding the power + both volume up and down.

Edit: This is what the forums say:

By pressing Volume up + Volume down + power button, you will feel a vibration after a second or so, that's when the bug reporting initiated.

To disable:

/system/bin/bugmailer.sh must be deleted/renamed.

There should be a folder on your SD card called "bug reports".

Try this

test2.removeAll(test1);

Set#removeAll

Removes from this set all of its elements that are contained in the specified collection (optional operation). If the specified collection is also a set, this operation effectively modifies this set so that its value is the asymmetric set difference of the two sets.

Per MSDN it is

By default, the maximum size of an Array is 2 gigabytes (GB).

In a 64-bit environment, you can avoid the size restriction by setting the enabled attribute of the gcAllowVeryLargeObjects configuration element to true in the run-time environment.

However, the array will still be limited to a total of 4 billion elements.

Refer Here http://msdn.microsoft.com/en-us/library/System.Array(v=vs.110).aspx

Note: Here I am focusing on the actual length of array by assuming that we will have enough hardware RAM.

I've got this error working in ASP.net. When I run the application from visual studio it worked all fine, but when I published the project and tested it , I've got that error "Autocomplete is not a function" in chrom Inspect debugger. I found out that the deferences between two environments were caused by a definition in web.config. in compilation tag. if assign debug="false" then all bundel definitions are executed and compilation is done as a release. if debug = true" then compilation is for a debug stage that not include bundeling and minifyning js library. Therefore the deferences between environments.

<system.web>
    <compilation debug="false" targetFramework="4.5.1"/>
    <httpRuntime targetFramework="4.5.1"/>
</system.web>

In addition, examining those two environments I saw that for debug environment everywhere (_Layout.cshtml) @Scripts.Render("~/bundles/jquery") was in the code, where (under APP_Start) BundleConfig.cs
bundles.Add(new ScriptBundle("~/bundles/jquery").Include( "~/Static/js/lib/jquery-{version}.js", "~/Static/js/lib/jquery-ui.js"));

it rended as:

<script src="/Static/js/lib/jquery-1.12.4.js"></script>
<script src="/Static/js/lib/jquery-ui.js"></script>

and the other environment (debug = false)

<script src="/bundles/jquery?v=YOLEkbKJYtNeDq0o56xjzXWKoYzrF5Vkqgyc9Cb0YgI1"></script>

In debug mode it works and the other one got the problem.

Aspecting the js lib I saw two files of jquery-ui:

jquery-ui.js jquery-ui.min.js

it turns out that both of them come as default from the template of new mvc project. When jquery-ui.min.js was deleted from the library the problem resolved.

I belive that even though jquery-ui.js was defined in BundleConfig.cs, actually jquery-ui.min.js was taken.

By the way, jquery-ui.min.js didn't include autocomple function apposed to jquery-ui.js that included it.

cheers.

Add the configuration manager file to connect to the database web.config

simplify the whole thing a bit, fix some issues with commas which will blow up some browsers:

  $(document).ready(function () {
       $("#register").validate({
           debug: true,
           rules: {
               year: {
                   required: function () {
                       return ($("#year option:selected").val() == "0");
                   }
               }
           },
           messages: {
               year: "Year Required"
           }
       });
   });

Jumping to an assumption, should your select not have this attribute validate="required:true"?

Using CSS, it can't be done. But, if you are using JQuery, something like this will do the trick:

$("img.myClass").attr("src", "http://somwhere");

The s.insert(0, x) form is the most common.

Whenever you see it though, it may be time to consider using a collections.deque instead of a list.

I tried:

ps aux | grep -w Z   # returns the zombies pid
ps o ppid {returned pid from previous command}   # returns the parent
kill -1 {the parent id from previous command}

this will work :)

SELECT field1, 
       field2,
       'example' AS newfield
FROM TABLE1

This will add a column called "newfield" to the output, and its value will always be "example".

This works:

function getBreakText($t) {
    return strtr($t, array('\\r\\n' => '<br>', '\\r' => '<br>', '\\n' => '<br>'));
}

For anyone stumbling over here like me - I had success with escaping the semicolon and the newline:

First step: the semicolon. This way, we do not break the ssh command:

ssh <host> echo test\;ls
                    ^ backslash!

Listed the remote hosts /home directory (logged in as root), whereas

ssh <host> echo test;ls
                    ^ NO backslash

listed the current working directory.

Next step: breaking up the line:

                      v another backslash!
ssh <host> echo test\;\
ls

This again listed the remote working directory - improved formatting:

ssh <host>\
  echo test\;\
  ls

If really nicer than here document or quotes around broken lines - well, not me to decide...

Instead of directly saving the private key Go to Conversions and Export SSh Key. Had the same issue and this worked for me

Disclaimer: I have been exposed to a significant amount of F77

The modern equivalent of goto (arguable, only my opinion, etc) is explicit exception handling:

Edited to highlight the code reuse better.

Pretend pseudocode in a fake python-like language with goto:

def myfunc1(x)
    if x == 0:
        goto LABEL1
    return 1/x

def myfunc2(z)
    if z == 0:
        goto LABEL1
    return 1/z

myfunc1(0) 
myfunc2(0)

:LABEL1
print 'Cannot divide by zero'.

Compared to python:

def myfunc1(x):
    return 1/x

def myfunc2(y):
    return 1/y


try:
    myfunc1(0)
    myfunc2(0)
except ZeroDivisionError:
    print 'Cannot divide by zero'

Explicit named exceptions are a significantly better way to deal with non-linear conditional branching.

A little update to Evan Mulawski answer to make it shorter

List<string> allLinesText = File.ReadAllLines(fileName).ToList()

0 if static or global, indeterminate if storage class is auto

C has always been very specific about the initial values of objects. If global or static, they will be zeroed. If auto, the value is indeterminate.

This was the case in pre-C89 compilers and was so specified by K&R and in DMR's original C report.

This was the case in C89, see section 6.5.7 Initialization.

If an object that has automatic storage duration is not initialized explicitely, its value is indeterminate. If an object that has static storage duration is not initialized explicitely, it is initialized implicitely as if every member that has arithmetic type were assigned 0 and every member that has pointer type were assigned a null pointer constant.

This was the case in C99, see section 6.7.8 Initialization.

If an object that has automatic storage duration is not initialized explicitly, its value is indeterminate. If an object that has static storage duration is not initialized explicitly, then:
— if it has pointer type, it is initialized to a null pointer;
— if it has arithmetic type, it is initialized to (positive or unsigned) zero;
— if it is an aggregate, every member is initialized (recursively) according to these rules;
— if it is a union, the first named member is initialized (recursively) according to these rules.

As to what exactly indeterminate means, I'm not sure for C89, C99 says:

3.17.2
indeterminate value
either an unspecified value or a trap representation

But regardless of what standards say, in real life, each stack page actually does start off as zero, but when your program looks at any auto storage class values, it sees whatever was left behind by your own program when it last used those stack addresses. If you allocate a lot of auto arrays you will see them eventually start neatly with zeroes.

You might wonder, why is it this way? A different SO answer deals with that question, see: https://stackoverflow.com/a/2091505/140740

There is no official, universal, convention for naming JavaScript files.

There are some various options:

• scriptName.js
• script-name.js
• script_name.js

are all valid naming conventions, however I prefer the jQuery suggested naming convention (for jQuery plugins, although it works for any JS)

• jquery.pluginname.js

The beauty to this naming convention is that it explicitly describes the global namespace pollution being added.

• foo.js adds window.foo
• foo.bar.js adds window.foo.bar

Because I left out versioning: it should come after the full name, preferably separated by a hyphen, with periods between major and minor versions:

• foo-1.2.1.js
• foo-1.2.2.js
• ...
• foo-2.1.24.js

Try this

You_command 1>output.log  2>&1

Your usage of &>x.file does work in bash4. sorry for that : (

Here comes some additional tips.

0, 1, 2...9 are file descriptors in bash.

0 stands for stdin, 1 stands for stdout, 2 stands for stderror. 3~9 is spare for any other temporary usage.

Any file descriptor can be redirected to other file descriptor or file by using operator > or >>(append).

Usage: <file_descriptor> > <filename | &file_descriptor>

Please reference to http://www.tldp.org/LDP/abs/html/io-redirection.html

Qt has a method for copying files:

#include <QFile>
QFile::copy("originalFile.example","copiedFile.example");

Note that to use this you have to install Qt (instructions here) and include it in your project (if you're using Windows and you're not an administrator, you can download Qt here instead). Also see this answer.

IEnumerable is an interface that defines one method GetEnumerator which returns an IEnumerator interface, this in turn allows readonly access to a collection. A collection that implements IEnumerable can be used with a foreach statement.

Definition

IEnumerable 

public IEnumerator GetEnumerator();

IEnumerator

public object Current;
public void Reset();
public bool MoveNext();

example code from codebetter.com

Below is avalancha TextView with added functionality for custom Font.

Usage:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:foo="http://schemas.android.com/apk/res-auto"
    android:layout_width="wrap_content"
    android:layout_height="match_parent" >

                <de.meinprospekt.androidhd.view.AutoFitText
                android:layout_width="wrap_content"
                android:layout_height="10dp"
                android:text="Small Text"
                android:textColor="#FFFFFF"
                android:textSize="100sp"
                foo:customFont="fonts/Roboto-Light.ttf" />

</FrameLayout>

Don't forget to add: xmlns:foo="http://schemas.android.com/apk/res-auto". Font should be in assets firectory

/**
 * https://stackoverflow.com/a/16174468/2075875 This class builds a new android Widget named AutoFitText which can be used instead of a TextView to
 * have the text font size in it automatically fit to match the screen width. Credits go largely to Dunni, gjpc, gregm and speedplane from
 * Stackoverflow, method has been (style-) optimized and rewritten to match android coding standards and our MBC. This version upgrades the original

I simply type ftp hostdomain.com and the very next prompt asked me to enter a name, if it wasn't the same as my current user.

I guess it depends on how your FTP is configured. That is, whether it assumes the same username (if not provided) or asks. the good news is that even without a solution, next time you face this it might Just Work™ for you :D

The solution is pretty straightforward. Suppose you want to use the "autumn" colormap scheme. The standard version:

cmap = matplotlib.cm.autumn

To reverse the colormap color spectrum, use get_cmap() function and append '_r' to the colormap title like this:

cmap_reversed = matplotlib.cm.get_cmap('autumn_r')

If you are writing xml, just use the classes provided by the framework to create the xml. You won't have to bother with escaping or anything.

Console.Write(new XElement("Data", "< > &"));

Will output

<Data>&lt; &gt; &amp;</Data>

If you need to read an XML file that is malformed, do not use regular expression. Instead, use the Html Agility Pack.

This might be too late but if you add

 worksheet.Columns.AutoFit();

or

 worksheet.Rows.AutoFit();

it also works.

Just do:

public void onClick() {
    if(condition == true) {
        return;
    }
    string.setText("This string should not change if condition = true");
}

It's redundant to write if(condition == true), just write if(condition) (This way, for example, you'll not write = by mistake).

If you're geting [object object] then use JSON.stringify

fs.writeFile('./data.json', JSON.stringify(obj) , 'utf-8');

It worked for me.

Export should be specific about which version of GCC/G++ to use, because if user had multiple compiler version, it would not compile successfully.

 export CC=path_of_gcc/gcc-version
 export CXX=path_of_g++/g++-version
 cmake  path_of_project_contain_CMakeList.txt
 make 

In case project use C++11 this can be handled by using -std=C++-11 flag in CMakeList.txt

To find the distance between 2 points, you need to find the length of the hypotenuse in a right angle triangle with a width and height equal to the vertical and horizontal distance:

Math.hypot(endX - startX, endY - startY)

First of all, shouldn't there be a CustomerId in the Invoices table? As it is, You can't perform this query for Invoices that have no payments on them as yet. If there are no payments on an invoice, that invoice will not even show up in the ouput of the query, even though it's an outer join...

Also, When a customer makes a payment, how do you know what Invoice to attach it to ? If the only way is by the InvoiceId on the stub that arrives with the payment, then you are (perhaps inappropriately) associating Invoices with the customer that paid them, rather than with the customer that ordered them... . (Sometimes an invoice can be paid by someone other than the customer who ordered the services)

Indeed, set in DOS has no option to allow for arithmetic. You could do a giant lookup table, though:

if %COUNTER%==249 set COUNTER=250
...
if %COUNTER%==3 set COUNTER=4
if %COUNTER%==2 set COUNTER=3
if %COUNTER%==1 set COUNTER=2
if %COUNTER%==0 set COUNTER=1

new Date().getTime()? This gives you a timestamp in milliseconds, which is the most accurate that JS will give you.

Update: As stated by vaughan, process.hrtime() is available within Node.js - its resolution are nanoseconds and therefore its much higher, also this doesn't mean it has to be more exact.

PS.: Just to be clearer, process.hrtime() returns you a tuple Array containing the current high-resolution real time in a [seconds, nanoseconds]

See the "Source Test Tools" link on the Software QA Testing and Test Tool Resources page for a list of similar tools.

I've used BoundsChecker,DevPartner Studio and Intel V-Tune in the past for profiling. I liked V-Tune the best; you could emulate various Intel chipsets and it would give you hints on how to optimize for that platform.

SET @NumRows = 1000000;

UPDATE  a
SET     a.IsDeleted = 1
FROM    dbo.AllTablesToDeleteFrom a
WHERE   a.TableName = @Table;
--flag this as deleted so you can move on to the next table to delete from

END; 

If you don't need the DATETIME value in the rest of your code, it'd be more efficient, simple and secure to use an UPDATE query with a sub-select, something like

UPDATE products SET t=(SELECT f FROM products WHERE id=17) WHERE id=42;

or in case it's in the same row in a single table, just

UPDATE products SET t=f WHERE id=42;

I never had time to play with clojure. But for scala vs groovy, this is words from James Strachan - Groovy creator

"Though my tip though for the long term replacement of javac is Scala. I'm very impressed with it! I can honestly say if someone had shown me the Programming in Scala book by Martin Odersky, Lex Spoon & Bill Venners back in 2003 I'd probably have never created Groovy."

Hi Here is my code to find the longest palindrome in the string. Kindly refer to the following link to understand the algorithm http://stevekrenzel.com/articles/longest-palnidrome

Test data used is HYTBCABADEFGHABCDEDCBAGHTFYW12345678987654321ZWETYGDE

 //Function GetPalindromeString

public static string GetPalindromeString(string theInputString)
 { 

        int j = 0;
        int k = 0;
        string aPalindrome = string.Empty;
        string aLongestPalindrome = string.Empty ;          
        for (int i = 1; i < theInputString.Length; i++)
        {
            k = i + 1;
            j = i - 1;
            while (j >= 0 && k < theInputString.Length)
            {
                if (theInputString[j] != theInputString[k])
                {
                    break;
                }
                else
                {
                    j--;
                    k++;
                }
                aPalindrome = theInputString.Substring(j + 1, k - j - 1);
                if (aPalindrome.Length > aLongestPalindrome.Length)
                {
                    aLongestPalindrome = aPalindrome;
                }
            }
        }
        return aLongestPalindrome;     
  }

You have to use absolute path to see if the file exists.

$abs_path = '/var/www/example.com/public_html/images/';
$file_url = 'http://www.example.com/images/' . $filename;

if (file_exists($abs_path . $filename)) {

    echo "The file exists. URL:" . $file_url;

} else {

    echo "The file does not exist";

}

If you are writing for CMS or PHP framework then as far as I know all of them have defined constant for document root path.

e.g WordPress uses ABSPATH which can be used globally for working with files on the server using your code as well as site url.

Wordpress example:

$image_path = ABSPATH . '/images/' . $filename;
$file_url = get_site_url() . '/images/' . $filename;

if (file_exists($image_path)) {

    echo "The file exists. URL:" . $file_url;

} else {

    echo "The file does not exist";

}

I'm going an extra mile here :). Because this code would no need much maintenance and pretty solid, I would write it with as shorthand if statement:

$image_path = ABSPATH . '/images/' . $filename;
$file_url = get_site_url() . '/images/' . $filename;

echo (file_exists($image_path))?'The file exists. URL:' . $file_url:'The file does not exist';

Shorthand IF statement explained:

$stringVariable = ($trueOrFalseComaprison > 0)?'String if true':'String if false';

Try this:

fname = "feed.txt"

num_lines = 0
num_words = 0
num_chars = 0

with open(fname, 'r') as f:
    for line in f:
        words = line.split()

        num_lines += 1
        num_words += len(words)
        num_chars += len(line)

Back to your code:

fname = "feed.txt"
fname = open('feed.txt', 'r')

what's the point of this? fname is a string first and then a file object. You don't really use the string defined in the first line and you should use one variable for one thing only: either a string or a file object.

for line in feed:
    lines = line.split('\n')

line is one line from the file. It does not make sense to split('\n') it.

[id^='someId'] will match all ids starting with someId.

[id$='someId'] will match all ids ending with someId.

[id*='someId'] will match all ids containing someId.

If you're looking for the name attribute just substitute id with name.

If you're talking about the tag name of the element I don't believe there is a way using querySelector

It is used in sequence comprehensions (like Python's list-comprehensions and generators, where you may use yield too).

It is applied in combination with for and writes a new element into the resulting sequence.

Simple example (from scala-lang)

/** Turn command line arguments to uppercase */
object Main {
  def main(args: Array[String]) {
    val res = for (a <- args) yield a.toUpperCase
    println("Arguments: " + res.toString)
  }
}

The corresponding expression in F# would be

[ for a in args -> a.toUpperCase ]

or

from a in args select a.toUpperCase 

in Linq.

Ruby's yield has a different effect.

public String TAG() {
    return this.getClass().getSimpleName();
}

private AtomicInteger lastFldId = null;

public int generateViewId(){

    if(lastFldId == null) {
        int maxFld = 0;
        String fldName = "";
        Field[] flds = R.id.class.getDeclaredFields();
        R.id inst = new R.id();

        for (int i = 0; i < flds.length; i++) {
            Field fld = flds[i];

            try {
                int value = fld.getInt(inst);

                if (value > maxFld) {
                    maxFld = value;
                    fldName = fld.getName();
                }
            } catch (IllegalAccessException e) {
                Log.e(TAG(), "error getting value for \'"+ fld.getName() + "\' " + e.toString());
            }
        }
        Log.d(TAG(), "maxId="+maxFld +"  name="+fldName);
        lastFldId = new AtomicInteger(maxFld);
    }

    return lastFldId.addAndGet(1);
}

If you want to add wsdl reference in .Net Core project, there is no "Add web reference" option.

To add the wsdl reference go to Solution Explorer, right-click on the References project item and then click on the Add Connected Service option.

Then click 'Microsoft WCF Web Service Reference':

Enter the file path into URI text box and import the WSDL:

It will generate a simple, very basic WCF client and you to use it something like this:

YourServiceClient client = new YourServiceClient();
client.DoSomething();

I had this issue as well, since the datepicker uses the input's z-index, I added the following css

#dialogID input,.modal-dialog input, .modal-dialog .input-group .form-control{
  z-index:inherit;
}

Just take the rule that applies to yours, either by parent id, class, or in my case a bootstrap dialog, using their input-group and form-control.

static renders variable local to the file which is generally a good thing, see for example this Wikipedia entry.

First and foremost, for newlines, the simplest thing to do is have separate print statements, like this:

print("Hello")
print("World.")
#the parentheses allow it to work in Python 2, or 3.

To have a line break, and still only one print statement, simply use the "\n" within, as follows:

print("Hello\nWorld.")

Below, I explain spaces, instead of line breaks...

I see allot of people here using the + notation, which personally, I find ugly. Example of what I find ugly:

x=' ';
print("Hello"+10*x+"world"); 

The example above is currently, as I type this the top up-voted answer. The programmer is obviously coming into Python from PHP as the ";" syntax at the end of every line, well simple isn't needed. The only reason it doesn't through an error in Python is because semicolons CAN be used in Python, really should only be used when you are trying to place two lines on one, for aesthetic reasons. You shouldn't place these at the end of every line in Python, as it only increases file-size.

Personally, I prefer to use %s notation. In Python 2.7, which I prefer, you don't need the parentheses, "(" and ")". However, you should include them anyways, so your script won't through errors, in Python 3.x, and will run in either.

Let's say you wanted your space to be 8 spaces, So what I would do would be the following in Python > 3.x

print("Hello", "World.",  sep=' '*8, end="\n")
# you don't need to specify end, if you don't want to, but I wanted you to know it was also an option
#if you wanted to have an 8 space prefix, and did not wish to use tabs for some reason, you could do the following.
print("%sHello World." % (' '*8))

The above method will work in Python 2.x as well, but you cannot add the "sep" and "end" arguments, those have to be done manually in Python < 3.

Therefore, to have an 8 space prefix, with a 4 space separator, the syntax which would work in Python 2, or 3 would be:

print("%sHello%sWorld." % (' '*8, ' '*4))

I hope this helps.

P.S. You also could do the following.

>>> prefix=' '*8
>>> sep=' '*2
>>> print("%sHello%sWorld." % (prefix, sep))
    Hello  World.

an inline solution combines Groot and Ivaylo suggestions in the format below:

onchange="(function(el){el.value=parseFloat(el.value).toFixed(2);})(this)"

When you have an assignment operator in a statement, the LHS of the operator must be something the language calls an lvalue. If the LHS of the operator does not evaluate to an lvalue, the value from the RHS cannot be assigned to the LHS.

You cannot use:

10 = 20;

since 10 does not evaluate to an lvalue.

You can use:

int i;
i = 20;

since i does evaluate to an lvalue.

You cannot use:

int i;
i + 1 = 20;

since i + 1 does not evaluate to an lvalue.

In your case, p + 1 does not evaluate to an lavalue. Hence, you cannot use

p + 1 = p;

One more important thing to realise: if you see iso-8859-1, it probably refers to Windows-1252 rather than ISO/IEC 8859-1. They differ in the range 0x80–0x9F, where ISO 8859-1 has the C1 control codes, and Windows-1252 has useful visible characters instead.

For example, ISO 8859-1 has 0x85 as a control character (in Unicode, U+0085, ``), while Windows-1252 has a horizontal ellipsis (in Unicode, U+2026 HORIZONTAL ELLIPSIS, …).

The WHATWG Encoding spec (as used by HTML) expressly declares iso-8859-1 to be a label for windows-1252, and web browsers do not support ISO 8859-1 in any way: the HTML spec says that all encodings in the Encoding spec must be supported, and no more.

Also of interest, HTML numeric character references essentially use Windows-1252 for 8-bit values rather than Unicode code points; per https://html.spec.whatwg.org/#numeric-character-reference-end-state, … will produce U+2026 rather than U+0085.

For simple input, like two prompts and two corresponding fixed responses, you could also use a "here document", the syntax of which looks like this:

test.sh <<!
y
pasword
!

The << prefixes a pattern, in this case '!'. Everything up to a line beginning with that pattern is interpreted as standard input. This approach is similar to the suggestion to pipe a multi-line echo into ssh, except that it saves the fork/exec of the echo command and I find it a bit more readable. The other advantage is that it uses built-in shell functionality so it doesn't depend on expect.

On OS X, where date does not support the %N flag, I recommend installing coreutils using Homebrew. This will give you access to a command called gdate that will behave as date does on Linux systems.

brew install coreutils

For a more "native" experience, you can always add this to your .bash_aliases:

alias date='gdate'

Then execute

$ date +%s%N

You could try:

.modal.modal-wide .modal-dialog {
  width: 90%;
}

.modal-wide .modal-body {
  overflow-y: auto;
}

Just add .modal-wide to your classes

Static methods in Python?

Is it possible to have static methods in Python so I can call them without initializing a class, like:

ClassName.StaticMethod()

Yes, static methods can be created like this (although it's a bit more Pythonic to use underscores instead of CamelCase for methods):

class ClassName(object):

    @staticmethod
    def static_method(kwarg1=None):
        '''return a value that is a function of kwarg1'''

The above uses the decorator syntax. This syntax is equivalent to

class ClassName(object):

    def static_method(kwarg1=None):
        '''return a value that is a function of kwarg1'''

    static_method = staticmethod(static_method)

This can be used just as you described:

ClassName.static_method()

A builtin example of a static method is str.maketrans() in Python 3, which was a function in the string module in Python 2.

Another option that can be used as you describe is the classmethod, the difference is that the classmethod gets the class as an implicit first argument, and if subclassed, then it gets the subclass as the implicit first argument.

class ClassName(object):

    @classmethod
    def class_method(cls, kwarg1=None):
        '''return a value that is a function of the class and kwarg1'''

Note that cls is not a required name for the first argument, but most experienced Python coders will consider it badly done if you use anything else.

These are typically used as alternative constructors.

new_instance = ClassName.class_method()

A builtin example is dict.fromkeys():

new_dict = dict.fromkeys(['key1', 'key2'])

Is correct?

<script>
$( "#box" ).one( "click", function() {
  $( this ).css( "width", "+=200" );
});
</script>

Simple Description!

The index is nothing but a data structure that stores the values for a specific column in a table. An index is created on a column of a table.

Example: We have a database table called User with three columns – Name, Age and Address. Assume that the User table has thousands of rows.

Now, let’s say that we want to run a query to find all the details of any users who are named 'John'. If we run the following query:

SELECT * FROM User 
WHERE Name = 'John'

The database software would literally have to look at every single row in the User table to see if the Name for that row is ‘John’. This will take a long time.

This is where index helps us: index is used to speed up search queries by essentially cutting down the number of records/rows in a table that needs to be examined.

How to create an index:

CREATE INDEX name_index
ON User (Name)

An index consists of column values(Eg: John) from one table, and those values are stored in a data structure.

So now the database will use the index to find employees named John because the index will presumably be sorted alphabetically by the Users name. And, because it is sorted, it means searching for a name is a lot faster because all names starting with a “J” will be right next to each other in the index!

My apache listens to 2 different ports,

Listen 8080
Listen 80  

I use the 80 when i want a transparent URL and do not put the port after the URL useful for google services that wont allow local url?

But i use the 8080 for internal developing where i use the port as a reference for a "dev environment"

your folder name is scripts..

and you are Referencing it like ../script/login.js

Also make sure that script folder is in your project directory

Thanks

It is very clear from your exception that it is trying to connect to localhost and not to 10.101.3.229

exception snippet : Could not connect to SMTP host: localhost, port: 25;

1.) Please check if there are any null check which is setting localhost as default value

2.) After restarting, if it is working fine, then it means that only at first-run, the proper value is been taken from Properties and from next run the value is set to default. So keep the property-object as a singleton one and use it all-over your project

Try MemLog. It does the job perfectly and quickly.

I'd suggest a RelativeLayout instead of a FrameLayout.

Assuming that you want to have the TextView always below the ImageView I'd use following layout.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">
    <ImageView
        android:id="@+id/imageview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerInParent="true"
        android:src="@drawable/icon"
        android:visibility="visible"/>
    <TextView
        android:id="@+id/textview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:layout_below="@id/imageview"
        android:gravity="center"
        android:text="@string/hello"/>
</RelativeLayout>

Note that if you set the visibility of an element to gone then the space that element would consume is gone whereas when you use invisible instead the space it'd consume will be preserved.

If you want to have the TextView on top of the ImageView then simply leave out the android:layout_alignParentTop or set it to false and on the TextView leave out the android:layout_below="@id/imageview" attribute. Like this.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">
    <ImageView
        android:id="@+id/imageview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="false"
        android:layout_centerInParent="true"
        android:src="@drawable/icon"
        android:visibility="visible"/>
    <TextView
        android:id="@+id/textview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:gravity="center"
        android:text="@string/hello"/>
</RelativeLayout>

I hope this is what you were looking for.

setUserVisibleHint() gets called sometimes before onCreateView() and sometimes after which causes trouble.

To overcome this you need to check isResumed() as well inside setUserVisibleHint() method. But in this case i realized setUserVisibleHint() gets called only if Fragment is resumed and visible, NOT when Created.

So if you want to update something when Fragment is visible, put your update function both in onCreate() and setUserVisibleHint():

@Override
public View onCreateView(...){
    ...
    myUIUpdate();
    ...        
}
  ....
@Override
public void setUserVisibleHint(boolean visible){
    super.setUserVisibleHint(visible);
    if (visible && isResumed()){
        myUIUpdate();
    }
}

UPDATE: Still i realized myUIUpdate() gets called twice sometimes, the reason is, if you have 3 tabs and this code is on 2nd tab, when you first open 1st tab, the 2nd tab is also created even it is not visible and myUIUpdate() is called. Then when you swipe to 2nd tab, myUIUpdate() from if (visible && isResumed()) is called and as a result,myUIUpdate() may get called twice in a second.

The other problem is !visible in setUserVisibleHint gets called both 1) when you go out of fragment screen and 2) before it is created, when you switch to fragment screen first time.

Solution:

private boolean fragmentResume=false;
private boolean fragmentVisible=false;
private boolean fragmentOnCreated=false;
...

@Override
public View onCreateView(...){
    ...
    //Initialize variables
    if (!fragmentResume && fragmentVisible){   //only when first time fragment is created
        myUIUpdate();
    }
    ...        
}

@Override
public void setUserVisibleHint(boolean visible){
    super.setUserVisibleHint(visible);
    if (visible && isResumed()){   // only at fragment screen is resumed
        fragmentResume=true;
        fragmentVisible=false;
        fragmentOnCreated=true;
        myUIUpdate();
    }else  if (visible){        // only at fragment onCreated
        fragmentResume=false;
        fragmentVisible=true;
        fragmentOnCreated=true;
    }
    else if(!visible && fragmentOnCreated){// only when you go out of fragment screen
        fragmentVisible=false;
        fragmentResume=false;
    }

fragmentResume,fragmentVisible: Makes sure myUIUpdate() in onCreateView() is called only when fragment is created and visible, not on resume. It also solves problem when you are at 1st tab, 2nd tab is created even if it is not visible. This solves that and checks if fragment screen is visible when onCreate.

fragmentOnCreated: Makes sure fragment is not visible, and not called when you create fragment first time. So now this if clause only gets called when you swipe out of fragment.

Update You can put all this code in BaseFragment code like this and override method.

I had the same error by in SQL Server Management Studio.

I found that to look at the more specific error, look at the log file created by the SQL Server. When I opened the log file, I found this error

Could not connect because the maximum number of ’2' user connections has already been reached. The system administrator can use sp_configure to increase the maximum value. The connection has been closed

I spend quite some time figuring this out. Finally running the following code fixed my problem.

sp_configure 'show advanced options', 1;
go

reconfigure
go

sp_configure 'user connections', 0
go

reconfigure
go

Edit

To view logs search for "logs" on windows startup button, click "view events logs". From there go to Applications under "Windows Logs". You can also choose "System" logs to see system wise errors. You can use filter on current logs by clicking "Filter Current Logs" on right side and then select "Error checkbox".

To clarify the excellent answer of Ryan Newsom and to adjust it for fragments and for the usual case that we want to navigate from a "master" ListView fragment to a "details" fragment and then back to the "master"

    private View root;
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
        {
           if(root == null){
             root = inflater.inflate(R.layout.myfragmentid,container,false);
             InitializeView(); 
           } 
           return root; 
        }

    public void InitializeView()
    {
        ListView listView = (ListView)root.findViewById(R.id.listviewid);
        BaseAdapter adapter = CreateAdapter();//Create your adapter here
        listView.setAdpater(adapter);
        //other initialization code
    }

The "magic" here is that when we navigate back from the details fragment to the ListView fragment, the view is not recreated, we don't set the ListView's adapter, so everything stays as we left it!

Don't forget to add this piece of code from the delegate or your view will be cut off or appear behind the table in some cases, relative to the height of your view/label.

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
    return 30;
}

You can adjust the pane title by setting the pane border in the tmux.conf for example like this:

###############
# pane border #
###############
set -g pane-border-status bottom
#colors for pane borders
setw -g pane-border-style fg=green,bg=black
setw -g pane-active-border-style fg=colour118,bg=black
setw -g automatic-rename off
setw -g pane-border-format ' #{pane_index} #{pane_title} : #{pane_current_path} '
# active pane normal, other shaded out?
setw -g window-style fg=colour28,bg=colour16
setw -g window-active-style fg=colour46,bg=colour16

Where pane_index, pane_title and pane_current_path are variables provided by tmux itself.

After reloading the config or starting a new tmux session, you can then set the title of the current pane like this:

tmux select-pane -T "fancy pane title";
#or
tmux select-pane -t paneIndexInteger -T "fancy pane title";

If all panes have some processes running, so you can't use the command line, you can also type the commands after pressing the prefix bind (C-b by default) and a colon (:) without having "tmux" in the front of the command:

select-pane -T "fancy pane title"
#or:
select-pane -t paneIndexInteger -T "fancy pane title"

This query here will list the total size that a table takes up - clustered index, heap and all nonclustered indices:

SELECT 
    s.Name AS SchemaName,
    t.NAME AS TableName,
    p.rows AS RowCounts,
    SUM(a.total_pages) * 8 AS TotalSpaceKB, 
    SUM(a.used_pages) * 8 AS UsedSpaceKB, 
    (SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceKB
FROM 
    sys.tables t
INNER JOIN 
    sys.schemas s ON s.schema_id = t.schema_id
INNER JOIN      
    sys.indexes i ON t.OBJECT_ID = i.object_id
INNER JOIN 
    sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id
INNER JOIN 
    sys.allocation_units a ON p.partition_id = a.container_id
WHERE 
    t.NAME NOT LIKE 'dt%'    -- filter out system tables for diagramming
    AND t.is_ms_shipped = 0
    AND i.OBJECT_ID > 255 
GROUP BY 
    t.Name, s.Name, p.Rows
ORDER BY 
    s.Name, t.Name

If you want to separate table space from index space, you need to use AND i.index_id IN (0,1) for the table space (index_id = 0 is the heap space, index_id = 1 is the size of the clustered index = data pages) and AND i.index_id > 1 for the index-only space

I don't know if something similar has been made by now or not, but I made a nice attribute search function using vars(). vars() creates a dictionary of the attributes of a class you pass through it.

class Player():
    def __init__(self):
        self.name = 'Bob'
        self.age = 36
        self.gender = 'Male'

s = vars(Player())
#From this point if you want to print all the attributes, just do print(s)

#If the class has a lot of attributes and you want to be able to pick 1 to see
#run this function
def play():
    ask = input("What Attribute?>: ")
    for key, value in s.items():
        if key == ask:
            print("self.{} = {}".format(key, value))
            break
    else:
        print("Couldn't find an attribute for self.{}".format(ask))

I'm developing a pretty massive Text Adventure in Python, my Player class so far has over 100 attributes. I use this to search for specific attributes I need to see.

It's simple Ctrl + C ; Ctrl + V , check this link. As long as you don't select any text, this will duplicate the line the cursor is over when you press Ctrl+C.

The method len() returns the number of elements in the list.

Syntax:

len(myArray)

Eg:

myArray = [1, 2, 3]
len(myArray)

Output:

3
