That means a topic is appropriate. A queue means a message goes to one and only one possible subscriber. A topic goes to each and every subscriber.

Make sure if all the spring jar file's version in your build path and the version mentioned in the xml file are same.

I'm using zeroMQ. I wanted a simple message passing system and I don't need the complication of a broker. I also don't want a huge Java oriented enterprise system.

If you want a fast, simple system and you need to support multiple languages (I use C and .net) then I'd recommend looking at 0MQ.

In my case I had a pem file which contained two certificates and an encrypted private key to be used in mutual SSL authentication. So my pem file looked like this:

-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----
-----BEGIN RSA PRIVATE KEY-----
Proc-Type: 4,ENCRYPTED
DEK-Info: DES-EDE3-CBC,C8BF220FC76AA5F9
...
-----END RSA PRIVATE KEY-----
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----

Here is what I did:

Split the file into three separate files, so that each one contains just one entry, starting with "---BEGIN.." and ending with "---END.." lines. Lets assume we now have three files: cert1.pem cert2.pem and pkey.pem

Convert pkey.pem into DER format using openssl and the following syntax:

openssl pkcs8 -topk8 -nocrypt -in pkey.pem -inform PEM -out pkey.der -outform DER

Note, that if the private key is encrypted you need to supply a password( obtain it from the supplier of the original pem file ) to convert to DER format, openssl will ask you for the password like this: "enter a pass phraze for pkey.pem: " If conversion is successful, you will get a new file called "pkey.der"

Create a new java key store and import the private key and the certificates:

String keypass = "password";  // this is a new password, you need to come up with to protect your java key store file
String defaultalias = "importkey";
KeyStore ks = KeyStore.getInstance("JKS", "SUN");

// this section does not make much sense to me, 
// but I will leave it intact as this is how it was in the original example I found on internet:   
ks.load( null, keypass.toCharArray());
ks.store( new FileOutputStream ( "mykeystore"  ), keypass.toCharArray());
ks.load( new FileInputStream ( "mykeystore" ),    keypass.toCharArray());
// end of section..


// read the key file from disk and create a PrivateKey

FileInputStream fis = new FileInputStream("pkey.der");
DataInputStream dis = new DataInputStream(fis);
byte[] bytes = new byte[dis.available()];
dis.readFully(bytes);
ByteArrayInputStream bais = new ByteArrayInputStream(bytes);

byte[] key = new byte[bais.available()];
KeyFactory kf = KeyFactory.getInstance("RSA");
bais.read(key, 0, bais.available());
bais.close();

PKCS8EncodedKeySpec keysp = new PKCS8EncodedKeySpec ( key );
PrivateKey ff = kf.generatePrivate (keysp);


// read the certificates from the files and load them into the key store:

Collection  col_crt1 = CertificateFactory.getInstance("X509").generateCertificates(new FileInputStream("cert1.pem"));
Collection  col_crt2 = CertificateFactory.getInstance("X509").generateCertificates(new FileInputStream("cert2.pem"));

Certificate crt1 = (Certificate) col_crt1.iterator().next();
Certificate crt2 = (Certificate) col_crt2.iterator().next();
Certificate[] chain = new Certificate[] { crt1, crt2 };

String alias1 = ((X509Certificate) crt1).getSubjectX500Principal().getName();
String alias2 = ((X509Certificate) crt2).getSubjectX500Principal().getName();

ks.setCertificateEntry(alias1, crt1);
ks.setCertificateEntry(alias2, crt2);

// store the private key
ks.setKeyEntry(defaultalias, ff, keypass.toCharArray(), chain );

// save the key store to a file         
ks.store(new FileOutputStream ( "mykeystore" ),keypass.toCharArray());

(optional) Verify the content of your new key store:

keytool -list -keystore mykeystore -storepass password

Keystore type: JKS Keystore provider: SUN

Your keystore contains 3 entries

cn=...,ou=...,o=.., Sep 2, 2014, trustedCertEntry, Certificate fingerprint (SHA1): 2C:B8: ...

importkey, Sep 2, 2014, PrivateKeyEntry, Certificate fingerprint (SHA1): 9C:B0: ...

cn=...,o=...., Sep 2, 2014, trustedCertEntry, Certificate fingerprint (SHA1): 83:63: ...

(optional) Test your certificates and private key from your new key store against your SSL server: ( You may want to enable debugging as an VM option: -Djavax.net.debug=all )

        char[] passw = "password".toCharArray();
        KeyStore ks = KeyStore.getInstance("JKS", "SUN");
        ks.load(new FileInputStream ( "mykeystore" ), passw );

        KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
        kmf.init(ks, passw);

        TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
        tmf.init(ks);
        TrustManager[] tm = tmf.getTrustManagers();

        SSLContext sclx = SSLContext.getInstance("TLS");
        sclx.init( kmf.getKeyManagers(), tm, null);

        SSLSocketFactory factory = sclx.getSocketFactory();
        SSLSocket socket = (SSLSocket) factory.createSocket( "192.168.1.111", 443 );
        socket.startHandshake();

        //if no exceptions are thrown in the startHandshake method, then everything is fine..

Finally register your certificates with HttpsURLConnection if plan to use it:

        char[] passw = "password".toCharArray();
        KeyStore ks = KeyStore.getInstance("JKS", "SUN");
        ks.load(new FileInputStream ( "mykeystore" ), passw );

        KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
        kmf.init(ks, passw);

        TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
        tmf.init(ks);
        TrustManager[] tm = tmf.getTrustManagers();

        SSLContext sclx = SSLContext.getInstance("TLS");
        sclx.init( kmf.getKeyManagers(), tm, null);

        HostnameVerifier hv = new HostnameVerifier()
        {
            public boolean verify(String urlHostName, SSLSession session)
            {
                if (!urlHostName.equalsIgnoreCase(session.getPeerHost()))
                {
                    System.out.println("Warning: URL host '" + urlHostName + "' is different to SSLSession host '" + session.getPeerHost() + "'.");
                }
                return true;
            }
        };

        HttpsURLConnection.setDefaultSSLSocketFactory( sclx.getSocketFactory() );
        HttpsURLConnection.setDefaultHostnameVerifier(hv);

I encountered a similar problem when I was using the below to obtain connection factory ConnectionFactory factory = new
ActiveMQConnectionFactory("admin","admin","tcp://:61616");

Its resolved when I changed it to the below

ConnectionFactory factory = new ActiveMQConnectionFactory("tcp://:61616");

The below then showed that my Q size was increasing.. http://:8161/admin/queues.jsp

DataFrames are based on RDDs. RDDs are immutable structures and do not allow updating elements on-site. To change values, you will need to create a new DataFrame by transforming the original one either using the SQL-like DSL or RDD operations like map.

The above answers fill not work if you have a lot of nested objects. Instead you can pick the function param from here - https://github.com/knowledgecode/jquery-param/blob/master/jquery-param.js It worked very well for me!

    var param = function (a) {
    var s = [], rbracket = /\[\]$/,
        isArray = function (obj) {
            return Object.prototype.toString.call(obj) === '[object Array]';
        }, add = function (k, v) {
            v = typeof v === 'function' ? v() : v === null ? '' : v === undefined ? '' : v;
            s[s.length] = encodeURIComponent(k) + '=' + encodeURIComponent(v);
        }, buildParams = function (prefix, obj) {
            var i, len, key;

            if (prefix) {
                if (isArray(obj)) {
                    for (i = 0, len = obj.length; i < len; i++) {
                        if (rbracket.test(prefix)) {
                            add(prefix, obj[i]);
                        } else {
                            buildParams(prefix + '[' + (typeof obj[i] === 'object' ? i : '') + ']', obj[i]);
                        }
                    }
                } else if (obj && String(obj) === '[object Object]') {
                    for (key in obj) {
                        buildParams(prefix + '[' + key + ']', obj[key]);
                    }
                } else {
                    add(prefix, obj);
                }
            } else if (isArray(obj)) {
                for (i = 0, len = obj.length; i < len; i++) {
                    add(obj[i].name, obj[i].value);
                }
            } else {
                for (key in obj) {
                    buildParams(key, obj[key]);
                }
            }
            return s;
        };

    return buildParams('', a).join('&').replace(/%20/g, '+');
};

Best option is create new table with same properties

CREATE TABLE <NEW.NAME.TABLE> LIKE <TABLE.CRASHED>;
INSERT INTO <NEW.NAME.TABLE> SELECT * FROM <TABLE.CRASHED>;

Rename NEW.NAME.TABLE and TABLE.CRASH

RENAME TABLE <TABLE.CRASHED> TO <TABLE.CRASHED.BACKUP>;
RENAME TABLE <NEW.NAME.TABLE> TO <TABLE.CRASHED>;

After work well, delete

DROP TABLE <TABLE.CRASHED.BACKUP>;

for this you have to create a custom LayoutManager

public class LinearLayoutManagerWithSmoothScroller extends LinearLayoutManager {

    public LinearLayoutManagerWithSmoothScroller(Context context) {
        super(context, VERTICAL, false);
    }

    public LinearLayoutManagerWithSmoothScroller(Context context, int orientation, boolean reverseLayout) {
        super(context, orientation, reverseLayout);
    }

    @Override
    public void smoothScrollToPosition(RecyclerView recyclerView, RecyclerView.State state,
                                       int position) {
        RecyclerView.SmoothScroller smoothScroller = new TopSnappedSmoothScroller(recyclerView.getContext());
        smoothScroller.setTargetPosition(position);
        startSmoothScroll(smoothScroller);
    }

    private class TopSnappedSmoothScroller extends LinearSmoothScroller {
        public TopSnappedSmoothScroller(Context context) {
            super(context);

        }

        @Override
        public PointF computeScrollVectorForPosition(int targetPosition) {
            return LinearLayoutManagerWithSmoothScroller.this
                    .computeScrollVectorForPosition(targetPosition);
        }

        @Override
        protected int getVerticalSnapPreference() {
            return SNAP_TO_START;
        }
    }
}

use this for your RecyclerView and call smoothScrollToPosition.

example :

 recyclerView.setLayoutManager(new LinearLayoutManagerWithSmoothScroller(context));
 recyclerView.smoothScrollToPosition(position);

this will scroll to top of the RecyclerView item of specified position.

hope this helps.

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

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

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

At original time of writing to uninstall:

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

Edit: As of 2020 to uninstall:

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

For Access, you can use the SQL Select query I present here:

For example you have this table:

CLIENTE|| NOMBRES || MAIL

888 || T800 ARNOLD || [email protected]

123 || JOHN CONNOR || [email protected]

125 || SARAH CONNOR ||[email protected]

And you need to select only distinct mails. You can do it with this:

SQL SELECT:

SELECT MAX(p.CLIENTE) AS ID_CLIENTE
, (SELECT TOP 1 x.NOMBRES 
    FROM Rep_Pre_Ene_MUESTRA AS x 
    WHERE x.MAIL=p.MAIL 
     AND x.CLIENTE=(SELECT MAX(l.CLIENTE) FROM Rep_Pre_Ene_MUESTRA AS l WHERE x.MAIL=l.MAIL)) AS NOMBRE, 
p.MAIL
FROM Rep_Pre_Ene_MUESTRA AS p
GROUP BY p.MAIL;

You can use this to select the maximum ID, the correspondent name to that maximum ID , you can add any other attribute that way. Then at the end you put the distinct column to filter and you only group it with that last distinct column.

This will bring you the maximum ID with the correspondent data, you can use min or any other functions and you replicate that function to the sub-queries.

This select will return:

CLIENTE|| NOMBRES || MAIL

888 || T800 ARNOLD || [email protected]

125 || SARAH CONNOR ||[email protected]

Remember to index the columns you select and the distinct column must have not numeric data all in upper case or in lower case, or else it won't work. This will work with only one registered mail as well. Happy coding!!!

The shortest way i have used

{{ Request::get('a') }}

Here's my version that is able to escape '{', and clean up those unassigned place holders.

function getStringFormatPlaceHolderRegEx(placeHolderIndex) {
    return new RegExp('({)?\\{' + placeHolderIndex + '\\}(?!})', 'gm')
}

function cleanStringFormatResult(txt) {
    if (txt == null) return "";

    return txt.replace(getStringFormatPlaceHolderRegEx("\\d+"), "");
}

String.prototype.format = function () {
    var txt = this.toString();
    for (var i = 0; i < arguments.length; i++) {
        var exp = getStringFormatPlaceHolderRegEx(i);
        txt = txt.replace(exp, (arguments[i] == null ? "" : arguments[i]));
    }
    return cleanStringFormatResult(txt);
}
String.format = function () {
    var s = arguments[0];
    if (s == null) return "";

    for (var i = 0; i < arguments.length - 1; i++) {
        var reg = getStringFormatPlaceHolderRegEx(i);
        s = s.replace(reg, (arguments[i + 1] == null ? "" : arguments[i + 1]));
    }
    return cleanStringFormatResult(s);
}

The above answers offer somewhat clumsy solutions for the following reasons:

1. I don't like having to wrap the input first and then getting the html, it is very involved and dirty.

2. Cross browser JS is handy and it seems that in this case there are too many unknowns to reliably use type switching (which, again, is a bit dirty) and setting value to ''

So I offer you my jQuery based solution:

$('#myinput').replaceWith($('#myinput').clone())

It does what it says, it replaces the input with a clone of itself. The clone won't have the file selected.

Advantages:

1. Simple and understandable code
2. No clumsy wrapping or type switching
3. Cross browser compatibility (correct me if I am wrong here)

Result: Happy programmer

This solution work on my case i am using ubuntu 16.04, VirtualBox 2.7.2 and genymotion 2.7.2 Same error come in my system i have followed simple step and my problem was solve

1. $ LD_LIBRARY_PATH=/usr/local/lib64/:$LD_LIBRARY_PATH
2. $ export LD_LIBRARY_PATH
3. $ sudo apt-add-repository ppa:ubuntu-toolchain-r/test
4. $ sudo apt-get update
5. $ sudo apt-get install gcc-4.9 g++-4.9

I hope this will work for you

Here is my own. Doesn't work for complex cases, but for a simple array of Objects, it's good enough.

  deepClone(oldArray: Object[]) {
    let newArray: any = [];
    oldArray.forEach((item) => {
      newArray.push(Object.assign({}, item));
    });
    return newArray;
  }

CATALINA_HOME vs CATALINA_BASE

If you're running multiple instances, then you need both variables, otherwise only CATALINA_HOME.

In other words: CATALINA_HOME is required and CATALINA_BASE is optional.

CATALINA_HOME represents the root of your Tomcat installation.

Optionally, Tomcat may be configured for multiple instances by defining $CATALINA_BASE for each instance. If multiple instances are not configured, $CATALINA_BASE is the same as $CATALINA_HOME.

See: Apache Tomcat 7 - Introduction

Running with separate CATALINA_HOME and CATALINA_BASE is documented in RUNNING.txt which say:

The CATALINA_HOME and CATALINA_BASE environment variables are used to specify the location of Apache Tomcat and the location of its active configuration, respectively.

You cannot configure CATALINA_HOME and CATALINA_BASE variables in the setenv script, because they are used to find that file.

For example:

(4.1) Tomcat can be started by executing one of the following commands:

  %CATALINA_HOME%\bin\startup.bat         (Windows)

  $CATALINA_HOME/bin/startup.sh           (Unix)

or

  %CATALINA_HOME%\bin\catalina.bat start  (Windows)

  $CATALINA_HOME/bin/catalina.sh start    (Unix)

Multiple Tomcat Instances

In many circumstances, it is desirable to have a single copy of a Tomcat binary distribution shared among multiple users on the same server. To make this possible, you can set the CATALINA_BASE environment variable to the directory that contains the files for your 'personal' Tomcat instance.

When running with a separate CATALINA_HOME and CATALINA_BASE, the files and directories are split as following:

In CATALINA_BASE:

• bin - Only: setenv.sh (*nix) or setenv.bat (Windows), tomcat-juli.jar
• conf - Server configuration files (including server.xml)
• lib - Libraries and classes, as explained below
• logs - Log and output files
• webapps - Automatically loaded web applications
• work - Temporary working directories for web applications
• temp - Directory used by the JVM for temporary files>

In CATALINA_HOME:

• bin - Startup and shutdown scripts
• lib - Libraries and classes, as explained below
• endorsed - Libraries that override standard "Endorsed Standards". By default it's absent.

How to check

The easiest way to check what's your CATALINA_BASE and CATALINA_HOME is by running startup.sh, for example:

$ /usr/share/tomcat7/bin/startup.sh
Using CATALINA_BASE:   /usr/share/tomcat7
Using CATALINA_HOME:   /usr/share/tomcat7

You may also check where the Tomcat files are installed, by dpkg tool as below (Debian/Ubuntu):

dpkg -L tomcat7-common

This is a rather late answer, but you can use

body {
   transform: scale(1.1);
   transform-origin: 0 0;
   // add prefixed versions too.
}

to zoom the page by 110%. Although the zoom style is there, Firefox still does not support it sadly.

Also, this is slightly different than your zoom. The css transform works like an image zoom, so it will enlarge your page but not cause reflow, etc.

Edit updated the transform origin.

You cannot really maintain state in a filter/lambda expression (unless abusing the global namespace). You can however achieve something similar using the accumulated result being passed around in a reduce() expression:

>>> f = lambda a, b: (a.append(b) or a) if (b not in a) else a
>>> input = ["foo", u"", "bar", "", "", "x"]
>>> reduce(f, input, [])
['foo', u'', 'bar', 'x']
>>> 

You can, of course, tweak the condition a bit. In this case it filters out duplicates, but you can also use a.count(""), for example, to only restrict empty strings.

Needless to say, you can do this but you really shouldn't. :)

Lastly, you can do anything in pure Python lambda: http://vanderwijk.info/blog/pure-lambda-calculus-python/

This could be a little tricky thing but the secure way is to set a javascript cookie, then picking it up by php cookie variable.Then Assign this php variable to an php session that will hold the data more securely than cookie.Then delete the cookie using javascript and redirect the page to itself. Given that you have added an php command to catch the variable, you will get it.

Sounds like you are using Microsoft Visual C++. If that is the case, then the most possibility is that you don't compile your two.cpp with one.cpp (one.cpp is the implementation for one.h).

If you are from command line (cmd.exe), then try this first: cl -o two.exe one.cpp two.cpp

If you are from IDE, right click on the project name from Solution Explore. Then choose Add, Existing Item.... Add one.cpp into your project.

The admin and manager apps are two separate things. Here's a snapshot of a tomcat-users.xml file that works, try this:

<?xml version='1.0' encoding='utf-8'?>  
<tomcat-users>  
    <role rolename="tomcat"/>  
    <role rolename="role1"/>  
    <role rolename="manager"/>  
    <user username="tomcat" password="tomcat" roles="tomcat"/>  
    <user username="both" password="tomcat" roles="tomcat,role1"/>  
    <user username="role1" password="tomcat" roles="role1"/>  
    <user username="USERNAME" password="PASSWORD" roles="manager,tomcat,role1"/>  
</tomcat-users>  

It works for me very well

How to Install MongoDB on Ubuntu 16.04

I had the same mistake. Finally, I found out that I needed to set the port number

The default port number for the mongo command is 27017

But the default port number in mongo.conf is 29999

I know that question is a bit old but

In root of project where Pipfile is located you could run

pipenv --venv

which returns

/Users/your_user_name/.local/share/virtualenvs/model-N-S4uBGU

and then remove this env by typing

rm -rf /Users/your_user_name/.local/share/virtualenvs/model-N-S4uBGU

A simple way would be:

print str(count) + '  ' + str(conv)

If you need more spaces, simply add them to the string:

print str(count) + '    ' + str(conv)

A fancier way, using the new syntax for string formatting:

print '{0}  {1}'.format(count, conv)

Or using the old syntax, limiting the number of decimals to two:

print '%d  %.2f' % (count, conv)

Let's say you want to build: u(n+1)=f(u(n)) with u(0)=u0

One solution is to define a simple recursive function:

u0 = ...

def f(x):
  ...

def u(n):
  if n==0: return u0
  return f(u(n-1))

Unfortunately, if you want to calculate high values of u, you will run into a stack overflow error.

Another solution is a simple loop:

def u(n):
  ux = u0
  for i in xrange(n):
    ux=f(ux)
  return ux

But if you want multiple values of u for different values of n, this is suboptimal. You could cache all values in an array, but you may run into an out of memory error. You may want to use generators instead:

def u(n):
  ux = u0
  for i in xrange(n):
    ux=f(ux)
  yield ux

for val in u(1000):
  print val

There are many other options, but I guess these are the main ones.

Note: This assumes that you will declare constants for row and column indexes named COLUMN_HEADING_ROW, FIRST_COL, and LAST_COL, and that _xlSheet is the name of the ExcelSheet (using Microsoft.Interop.Excel)

First, define the range:

var columnHeadingsRange = _xlSheet.Range[
    _xlSheet.Cells[COLUMN_HEADING_ROW, FIRST_COL],
    _xlSheet.Cells[COLUMN_HEADING_ROW, LAST_COL]];

Then, set the background color of that range:

columnHeadingsRange.Interior.Color = XlRgbColor.rgbSkyBlue;

Finally, set the font color:

columnHeadingsRange.Font.Color = XlRgbColor.rgbWhite;

And here's the code combined:

var columnHeadingsRange = _xlSheet.Range[
    _xlSheet.Cells[COLUMN_HEADING_ROW, FIRST_COL],
    _xlSheet.Cells[COLUMN_HEADING_ROW, LAST_COL]];

columnHeadingsRange.Interior.Color = XlRgbColor.rgbSkyBlue;

columnHeadingsRange.Font.Color = XlRgbColor.rgbWhite;

In combination with lists, dicts and sets, there are also another interesting python objects, OrderedDicts.

Ordered dictionaries are just like regular dictionaries but they remember the order that items were inserted. When iterating over an ordered dictionary, the items are returned in the order their keys were first added.

OrderedDicts could be useful when you need to preserve the order of the keys, for example working with documents: It's common to need the vector representation of all terms in a document. So using OrderedDicts you can efficiently verify if a term has been read before, add terms, extract terms, and after all the manipulations you can extract the ordered vector representation of them.

One thing to add, the url is case sensitive. Note that:

apps.facebook.com/HELLO

is different in the linter's eyes then

apps.facebook.com/hello

Be sure to use the exact site url that was entered in the developer settings for the app. The linter will return the properties otherwise but will not refresh the cache.

We can use date -d option

1) Change format to "%Y-%m-%d" format i.e 20121212 to 2012-12-12

date -d '20121212' +'%Y-%m-%d'

2)Get next or last day from a given date=20121212. Like get a date 7 days in past with specific format

date -d '20121212 -7 days' +'%Y-%m-%d'

3) If we are getting date in some variable say dat

dat2=$(date -d "$dat -1 days" +'%Y%m%d')

PYTHONPATH only affects import statements, not the top-level Python interpreter's lookup of python files given as arguments.

Needing PYTHONPATH to be set is not a great idea - as with anything dependent on environment variables, replicating things consistently across different machines gets tricky. Better is to use Python 'packages' which can be installed (using 'pip', or distutils) in system-dependent paths which Python already knows about.

Have a read of https://the-hitchhikers-guide-to-packaging.readthedocs.org/en/latest/ - 'The Hitchhiker's Guide to Packaging', and also http://docs.python.org/3/tutorial/modules.html - which explains PYTHONPATH and packages at a lower level.

A broader solution, adding the possibility to replace the suffix (you can remove by replacing with the empty string) and to set the maximum number of replacements:

def replacesuffix(s,old,new='',limit=1):
    """
    String suffix replace; if the string ends with the suffix given by parameter `old`, such suffix is replaced with the string given by parameter `new`. The number of replacements is limited by parameter `limit`, unless `limit` is negative (meaning no limit).

    :param s: the input string
    :param old: the suffix to be replaced
    :param new: the replacement string. Default value the empty string (suffix is removed without replacement).
    :param limit: the maximum number of replacements allowed. Default value 1.
    :returns: the input string with a certain number (depending on parameter `limit`) of the rightmost occurrences of string given by parameter `old` replaced by string given by parameter `new`
    """
    if s[len(s)-len(old):] == old and limit != 0:
        return replacesuffix(s[:len(s)-len(old)],old,new,limit-1) + new
    else:
        return s

In your case, given the default arguments, the desired result is obtained with:

replacesuffix('abcdc.com','.com')
>>> 'abcdc'

Some more general examples:

replacesuffix('whatever-qweqweqwe','qwe','N',2)
>>> 'whatever-qweNN'

replacesuffix('whatever-qweqweqwe','qwe','N',-1)
>>> 'whatever-NNN'

replacesuffix('12.53000','0',' ',-1)
>>> '12.53   '

This came across while working on a project on linux platform.

exec('wget http://<url to the php script>)

This runs as if you run the script from browser.

Hope this helps!!

Without any libraries, you could do this instead:

def to_frequency_table(data):
    frequencytable = {}
    for key in data:
        if key in frequencytable:
            frequencytable[key] += 1
        else:
            frequencytable[key] = 1
    return frequencytable

Example:

to_frequency_table([1,1,1,1,2,3,4,4])
>>> {1: 4, 2: 1, 3: 1, 4: 2}

post in http
Put http.request.method == "POST" in the display filter of wireshark to only show POST requests. Click on the packet

Looks a lot like Oracle, but that doesn't work on SQL Server.

You can, instead, adopt the following syntax...

SELECT
  *
INTO
  new_table
FROM
  old_source(s)

If I may offer some suggestions (two years later but hopefully helpful to future readers):

• Factor out the common h2 element.
• Factor out the common ooooooooooooo text.
• Be aware of new XPath 2.0 if/then/else construct if using XSLT 2.0.

XSLT 1.0 Solution ^{_{(also works with XSLT 2.0)}}

<h2>
  <xsl:choose>
    <xsl:when test="$CreatedDate > $IDAppendedDate">m</xsl:when>
    <xsl:otherwise>d</xsl:otherwise>
  </xsl:choose>
  ooooooooooooo
</h2>

XSLT 2.0 Solution

<h2>
   <xsl:value-of select="if ($CreatedDate > $IDAppendedDate) then 'm' else 'd'"/>
   ooooooooooooo
</h2>

You can prefix the function declaration with extern “C” keyword, e.g.

extern “C” int Mycppfunction()

{

// Code goes here

return 0;

}

For more examples you can search more on Google about “extern” keyword. You need to do few more things, but it's not difficult you'll get lots of examples from Google.

In Linux or MacOS you can use:

date +%s

where

• +%s, seconds since 1970-01-01 00:00:00 UTC. (GNU Coreutils 8.24 Date manual)

Example output now 1454000043.

As Nayan said the Path has to updated properly in my case the apache-maven was installed in C:\apache-maven and settings.xml was found inside C:\apache-maven\conf\settings.xml

if this doesn't work go to your local repos
in my case C:\Users\<<"name">>.m2\
and search for .lastUpdated and delete them
then build the maven

Give the DIV a specific with in percentage or pixels and center it using CSS margin property.

Slightly different version I wrote that keeps track of the keys along the way to get there

def print_dict(v, prefix=''):
    if isinstance(v, dict):
        for k, v2 in v.items():
            p2 = "{}['{}']".format(prefix, k)
            print_dict(v2, p2)
    elif isinstance(v, list):
        for i, v2 in enumerate(v):
            p2 = "{}[{}]".format(prefix, i)
            print_dict(v2, p2)
    else:
        print('{} = {}'.format(prefix, repr(v)))

On your data, it'll print

data['xml']['config']['portstatus']['status'] = u'good'
data['xml']['config']['target'] = u'1'
data['xml']['port'] = u'11'

It's also easy to modify it to track the prefix as a tuple of keys rather than a string if you need it that way.

If you are on Ubuntu,

1. Login to your postgres user sudo su postgres
2. pg_dump -d <database_name> -t <table_name> > file.sql

Make sure that you are executing the command where the postgres user have write permissions (Example: /tmp)

Edit

If you want to dump the .sql in another computer, you may need to consider skipping the owner information getting saved into the .sql file.

You can use pg_dump --no-owner -d <database_name> -t <table_name> > file.sql

you never set d[a] to any value.

Because of this, d[a] evaluates to undefined, and you can't set properties on undefined.

If you add d[a] = {} right after d = {} things should work as expected.

Alternatively, you could use an object initializer:

d[a] = {
    greetings: b,
    data: c
};

Or you could set all the properties of d in an anonymous function instance:

d = new function () {
    this[a] = {
        greetings: b,
        data: c
    };
};

If you're in an environment that supports ES2015 features, you can use computed property names:

d = {
  [a]: {
    greetings: b,
    data: c
  }
};

Also check that you are not using validation groups as that validation wouldnt fire if the validationgroup property was set and not explicitly called via

 Page.Validate({Insert validation group name here});

You have two possibilities.

Method 1. XSD tool

1. Open Developer Command Prompt
   You can find it in Start Menu > Programs > Microsoft Visual Studio 2012 > Visual Studio Tools Or if you have Windows 8 can just start typing Developer Command Prompt in Start screen
2. Change location to your XML file directory by typing cd /D "C:\path\to\xml"
3. Create XSD file from your xml file by typing xsd file.xml
4. Create C# classes by typing xsd /c file.xsd

And that's it! You have generated C# classes from xml file in C:\path\to\xml\file.cs

Method 2 - Paste special

1. Copy content of your XML file to clipboard
2. Add to your solution new, empty class file (Shift+Alt+C)
3. Open that file and in menu click Edit > Paste special > Paste XML As Classes
   

And that's it!

Usage

Usage is very simple with this helper class:

using System;
using System.IO;
using System.Web.Script.Serialization; // Add reference: System.Web.Extensions
using System.Xml;
using System.Xml.Serialization;

namespace Helpers
{
    internal static class ParseHelpers
    {
        private static JavaScriptSerializer json;
        private static JavaScriptSerializer JSON { get { return json ?? (json = new JavaScriptSerializer()); } }

        public static Stream ToStream(this string @this)
        {
            var stream = new MemoryStream();
            var writer = new StreamWriter(stream);
            writer.Write(@this);
            writer.Flush();
            stream.Position = 0;
            return stream;
        }


        public static T ParseXML<T>(this string @this) where T : class
        {
            var reader = XmlReader.Create(@this.Trim().ToStream(), new XmlReaderSettings() { ConformanceLevel = ConformanceLevel.Document });
            return new XmlSerializer(typeof(T)).Deserialize(reader) as T;
        }

        public static T ParseJSON<T>(this string @this) where T : class
        {
            return JSON.Deserialize<T>(@this.Trim());
        }
    }
}

All you have to do now, is:

    public class JSONRoot
    {
        public catalog catalog { get; set; }
    }
    // ...

    string xml = File.ReadAllText(@"D:\file.xml");
    var catalog1 = xml.ParseXML<catalog>();

    string json = File.ReadAllText(@"D:\file.json");
    var catalog2 = json.ParseJSON<JSONRoot>();

Add this to an htaccess file (and see edit notes added below):

<IfModule mod_php5.c>
   php_value post_max_size 200M
   php_value upload_max_filesize 200M
   php_value memory_limit 300M
   php_value max_execution_time 259200
   php_value max_input_time 259200
   php_value session.gc_maxlifetime 1200
</IfModule>

2021 EDIT:

As PHP and Apache evolve and grow, I think it is important for me to take a moment to mention a few things to consider and possible "gotchas" to consider:

• PHP can be run as a module or as CGI. It is not recommended to run as CGI as it creates a lot of opportunities for attack vectors [Read More]. Running as a module (the safer option) will trigger the settings to be used if the specific module from <IfModule is loaded.
• The answer indicates to write mod_php5.c in the first line. If you are using PHP 7, you would replace that with mod_php7.c.
• Sometimes after you make changes to your .htaccess file, restarting Apache or NGINX will not work. The most common reason for this is you are running PHP-FPM, which runs as a separate process. You need to restart that as well.
• Remember these are settings that are normally defined in your php.ini config file(s). This method is usually only useful in the event your hosting provider does not give you access to change those files. In circumstances where you can edit the PHP configuration, it is recommended that you apply these settings there.
• Finally, it's important to note that not all php.ini settings can be configured via an .htaccess file. A file list of php.ini directives can be found here, and the only ones you can change are the ones in the changeable column with the modes PHP_INI_ALL or PHP_INI_PERDIR.

I was getting this error though there were no (obvious) brackets in my URL, and in my situation the --globoff command will not solve the issue.

For example (doing this on on mac in iTerm2):

for endpoint in $(grep some_string output.txt); do curl "http://1.2.3.4/api/v1/${endpoint}" ; done

I have grep aliased to "grep --color=always". As a result, the above command will result in this error, with some_string highlighted in whatever colour you have grep set to:

curl: (3) bad range in URL position 31:
http://1.2.3.4/api/v1/lalalasome_stringlalala

The terminal was transparently translating the [colour\codes]some_string[colour\codes] into the expected no-special-characters URL when viewed in terminal, but behind the scenes the colour codes were being sent in the URL passed to curl, resulting in brackets in your URL.

Solution is to not use match highlighting.

try to use this

<RadioGroup
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"       
    android:orientation="horizontal"
>    
    <RadioButton
        android:id="@+id/standard_delivery"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/Standard_delivery"

        android:layout_marginTop="4dp"
        android:textSize="12dp"
        android:onClick="onRadioButtonClicked"
        android:id="@+id/midnight_delivery"
    />    
</RadioGroup>

this is java class

public void onRadioButtonClicked(View view) {
        // Is the button now checked?
        boolean checked = ((RadioButton) view).isChecked();

        // Check which radio button was clicked
        switch(view.getId()) {
            case R.id.standard_delivery:
                if (checked)
                    Toast.makeText(DishActivity.this," standard delivery",Toast.LENGTH_LONG).show();
                    break;
            case R.id.midnight_delivery:
                if (checked)
                    Toast.makeText(DishActivity.this," midnight delivery",Toast.LENGTH_LONG).show();
                    break;
        }
    }

This is confusing. When you say "form object", do you mean "<select> element"? If not, your code won't work, so I'll assume your form variable is in fact a reference to a <select> element. Why do you want to rewrite this code? What you have has worked in all scriptable browsers since around 1996, and won't stop working any time soon. Doing it with jQuery will immediately make your code slower, more error-prone and less compatible across browsers.

Here's a function that uses your current code as a starting point and populates a <select> element from an object:

<select id="mySelect"></select>

<script type="text/javascript>

function populateSelect(select, optionsData) {
    var options = select.options, o, selected;
    options.length = 0;
    for (var i = 0, len = optionsData.length; i < len; ++i) {
        o = optionsData[i];
        selected = !!o.selected;
        options[i] = new Option(o.text, o.value, selected, selected);
    }
}

var optionsData = [
    {
        text: "Select a city / town in Sweden",
        value: ""
    },
    {
        text: "Melbourne",
        value: "Melbourne",
        selected: true
    }
];

populateSelect(document.getElementById("mySelect"), optionsData);

</script>

With Python 3.8, it's very easy.

https://docs.python.org/3/library/math.html#math.dist

math.dist(p, q)

Return the Euclidean distance between two points p and q, each given as a sequence (or iterable) of coordinates. The two points must have the same dimension.

Roughly equivalent to:

sqrt(sum((px - qx) ** 2.0 for px, qx in zip(p, q)))

Try to go into Design mode in Visual Studio, locate the button and double click the button that should setup the event. Otherwise once the button is selected in Design more, go to the properties and try setting it from there.

If you have a strong suspicion that the DOUBLE is actually a LONG, and you want to

1) get a handle on its EXACT value as a LONG

2) throw an error when its not a LONG

you can try something like this:

public class NumberUtils {

    /**
    * Convert a {@link Double} to a {@link Long}.
    * Method is for {@link Double}s that are actually {@link Long}s and we just
    * want to get a handle on it as one.
    */
    public static long getDoubleAsLong(double specifiedNumber) {
        Assert.isTrue(NumberUtils.isWhole(specifiedNumber));
        Assert.isTrue(specifiedNumber <= Long.MAX_VALUE && specifiedNumber >= Long.MIN_VALUE);
        // we already know its whole and in the Long range
        return Double.valueOf(specifiedNumber).longValue();
    }

    public static boolean isWhole(double specifiedNumber) {
        // http://stackoverflow.com/questions/15963895/how-to-check-if-a-double-value-has-no-decimal-part
        return (specifiedNumber % 1 == 0);
    }
}

Long is a subset of Double, so you might get some strange results if you unknowingly try to convert a Double that is outside of Long's range:

@Test
public void test() throws Exception {
    // Confirm that LONG is a subset of DOUBLE, so numbers outside of the range can be problematic
    Assert.isTrue(Long.MAX_VALUE < Double.MAX_VALUE);
    Assert.isTrue(Long.MIN_VALUE > -Double.MAX_VALUE); // Not Double.MIN_VALUE => read the Javadocs, Double.MIN_VALUE is the smallest POSITIVE double, not the bottom of the range of values that Double can possible be

    // Double.longValue() failure due to being out of range => results are the same even though I minus ten
    System.out.println("Double.valueOf(Double.MAX_VALUE).longValue(): " + Double.valueOf(Double.MAX_VALUE).longValue());
    System.out.println("Double.valueOf(Double.MAX_VALUE - 10).longValue(): " + Double.valueOf(Double.MAX_VALUE - 10).longValue());

    // casting failure due to being out of range => results are the same even though I minus ten
    System.out.println("(long) Double.valueOf(Double.MAX_VALUE): " + (long) Double.valueOf(Double.MAX_VALUE).doubleValue());
    System.out.println("(long) Double.valueOf(Double.MAX_VALUE - 10).longValue(): " + (long) Double.valueOf(Double.MAX_VALUE - 10).doubleValue());
}

This is a slightly improvised answer to ajsp answer using XML-RPC.

On the server-side when you convert the data, convert the numpy data to a string using the '.tostring()' method. This encodes the numpy ndarray as bytes string. On the client-side when you receive the data decode it using '.fromstring()' method. I wrote two simple functions for this. Hope this is helpful.

1. ndarray2str -- Converts numpy ndarray to bytes string.
2. str2ndarray -- Converts binary str back to numpy ndarray.

    def ndarray2str(a):
        # Convert the numpy array to string 
        a = a.tostring()

        return a

On the receiver side, the data is received as a 'xmlrpc.client.Binary' object. You need to access the data using '.data'.

    def str2ndarray(a):
        # Specify your data type, mine is numpy float64 type, so I am specifying it as np.float64
        a = np.fromstring(a.data, dtype=np.float64)
        a = np.reshape(a, new_shape)

        return a

Note: Only problem with this approach is that XML-RPC is very slow while sending large numpy arrays. It took me around 4 secs to send and receive a (10, 500, 500, 3) size numpy array for me.

I am using python 3.7.4.

2015 update, new MutationObserver is supported by modern browsers:

Chrome 18+, Firefox 14+, IE 11+, Safari 6+

If you need to support older ones, you may try to fall back to other approaches like the ones mentioned in this 5 (!) year old answer below. There be dragons. Enjoy :)

Someone else is changing the document? Because if you have full control over the changes you just need to create your own domChanged API - with a function or custom event - and trigger/call it everywhere you modify things.

The DOM Level-2 has Mutation event types, but older version of IE don't support it. Note that the mutation events are deprecated in the DOM3 Events spec and have a performance penalty.

You can try to emulate mutation event with onpropertychange in IE (and fall back to the brute-force approach if non of them is available).

For a full domChange an interval could be an over-kill. Imagine that you need to store the current state of the whole document, and examine every element's every property to be the same.

Maybe if you're only interested in the elements and their order (as you mentioned in your question), a getElementsByTagName("*") can work. This will fire automatically if you add an element, remove an element, replace elements or change the structure of the document.

I wrote a proof of concept:

(function (window) {
    var last = +new Date();
    var delay = 100; // default delay

    // Manage event queue
    var stack = [];

    function callback() {
        var now = +new Date();
        if (now - last > delay) {
            for (var i = 0; i < stack.length; i++) {
                stack[i]();
            }
            last = now;
        }
    }

    // Public interface
    var onDomChange = function (fn, newdelay) {
        if (newdelay) delay = newdelay;
        stack.push(fn);
    };

    // Naive approach for compatibility
    function naive() {

        var last = document.getElementsByTagName('*');
        var lastlen = last.length;
        var timer = setTimeout(function check() {

            // get current state of the document
            var current = document.getElementsByTagName('*');
            var len = current.length;

            // if the length is different
            // it's fairly obvious
            if (len != lastlen) {
                // just make sure the loop finishes early
                last = [];
            }

            // go check every element in order
            for (var i = 0; i < len; i++) {
                if (current[i] !== last[i]) {
                    callback();
                    last = current;
                    lastlen = len;
                    break;
                }
            }

            // over, and over, and over again
            setTimeout(check, delay);

        }, delay);
    }

    //
    //  Check for mutation events support
    //

    var support = {};

Usage:

onDomChange(function(){

});

This works on IE 5.5+, FF 2+, Chrome, Safari 3+ and Opera 9.6+

Here is a better way for doing it. Hope this helps

The END comes from the pager used to display the log (your are at that moment still inside it). Type q to exit it.

This is coming from JPA. In a very simple way:

• persist(entity) should be used with totally new entities, to add them to DB (if entity already exists in DB there will be EntityExistsException throw).

• merge(entity) should be used, to put entity back to persistence context if the entity was detached and was changed.

Just two steps needed:

1. Apply setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); after setContentView().

2. In the AndroidMainfest.xml, put this statement <activity android:name=".YOURCLASSNAME" android:screenOrientation="landscape" />

Hope it helps and happy coding :)

You can perform this task using window.location.reload();. As there are many ways to do this but I think it is the appropriate way to reload the same document with JavaScript. Here is the explanation

JavaScript window.location object can be used

• to get current page address (URL)
• to redirect the browser to another page
• to reload the same page

window: in JavaScript represents an open window in a browser.

location: in JavaScript holds information about current URL.

The location object is like a fragment of the window object and is called up through the window.location property.

location object has three methods:

1. assign(): used to load a new document
2. reload(): used to reload current document
3. replace(): used to replace current document with a new one

So here we need to use reload(), because it can help us in reloading the same document.

So use it like window.location.reload();.

Online demo on jsfiddle

To ask your browser to retrieve the page directly from the server not from the cache, you can pass a true parameter to location.reload(). This method is compatible with all major browsers, including IE, Chrome, Firefox, Safari, Opera.

You can try to rename the python executable in the python3 folder to python3, that is if it was named python formally... it worked for me

1:- Delete the framework from the Xcode project. Quit the Xcode.

2:- Open your project in XCode and go to file under Menu and select Add files to "YourProjectName".

3:- Select "YourFramwork.framework" in the directory where you keep it.

4:- Click on the Copy items if needed checkbox.

5:- Click Add.

Make sure that you have the framework added in both Embedded Binaries and Linked Frameworks and Libraries under Target settings - General. As shown in the following images:-

Apache FileUtil gives very handy methods to do the conversion

try {
    File file = new File(imagefilePath);
    byte[] byteArray = new byte[file.length()]();
    byteArray = FileUtils.readFileToByteArray(file);  
 }catch(Exception e){
     e.printStackTrace();

 }

After creating the project go to properties --> build path --> configure build path --> order and export tab and check jre and maven dependencies. You will then have the folder.

You can use

t1<- t1[-4:-6,-7:-9]  

or

t1 <- t1[-(4:6), -(7:9)]

or

t1 <- t1[-c(4, 5, 6), -c(7, 8, 9)]

You can pass vectors to select rows/columns to be deleted. First two methods are useful if you are trying to delete contiguous rows/columns. Third method is useful if You are trying to delete discrete rows/columns.

> t1 <- array(1:20, dim=c(10,10));

> t1[-c(1, 4, 6, 7, 9), -c(2, 3, 8, 9)]

     [,1] [,2] [,3] [,4] [,5] [,6]
[1,]    2   12    2   12    2   12
[2,]    3   13    3   13    3   13
[3,]    5   15    5   15    5   15
[4,]    8   18    8   18    8   18
[5,]   10   20   10   20   10   20

In browsers up to and including IE9, this is done through conditional comments.

<!--[if IE]>
<style type="text/css">
  IE specific CSS rules go here
</style>
<![endif]-->

The error occurred when I unknowingly tried plotting the image path instead of the image.

My code :

import cv2 as cv
from matplotlib import pyplot as plt
import pytesseract
from resizeimage import resizeimage

img = cv.imread("D:\TemplateMatch\\fitting.png") ------>"THIS IS THE WRONG USAGE"
#cv.rectangle(img,(29,2496),(604,2992),(255,0,0),5)
plt.imshow(img)

Correction: img = cv.imread("fitting.png") --->THIS IS THE RIGHT USAGE"

It's useful in situations where you have hidden internal state such as a cache. For example:

class HashTable
{
...
public:
    string lookup(string key) const
    {
        if(key == lastKey)
            return lastValue;

        string value = lookupInternal(key);

        lastKey = key;
        lastValue = value;

        return value;
    }

private:
    mutable string lastKey, lastValue;
};

And then you can have a const HashTable object still use its lookup() method, which modifies the internal cache.

Per this other post: Insert all values of a..., you can do the following:

INSERT INTO new_table (Foo, Bar, Fizz, Buzz)
SELECT Foo, Bar, Fizz, Buzz
FROM initial_table

It's important to specify the column names as indicated by the other answers.

another method to find Instance name- Right clck on Database name and select Properties, in this part you can see view connection properties in left down corner, click that then you can see the Instance name.

This should do it:

for (var i = 0; i < bank_holidays.length; i++) {
    if (bank_holidays[i] === '06/04/2012') {
        alert('LOL');
    }
}

jsFiddle

If reading the whole file is acceptable then use a deque.

from collections import deque
deque(f, maxlen=n)

Prior to 2.6, deques didn't have a maxlen option, but it's easy enough to implement.

import itertools
def maxque(items, size):
    items = iter(items)
    q = deque(itertools.islice(items, size))
    for item in items:
        del q[0]
        q.append(item)
    return q

If it's a requirement to read the file from the end, then use a gallop (a.k.a exponential) search.

def tail(f, n):
    assert n >= 0
    pos, lines = n+1, []
    while len(lines) <= n:
        try:
            f.seek(-pos, 2)
        except IOError:
            f.seek(0)
            break
        finally:
            lines = list(f)
        pos *= 2
    return lines[-n:]

If using AngularJS 1.2 you can use 'track by' to tell Angular how to compare objects.

<select 
    ng-model="Choice.SelectedOption"                 
    ng-options="choice.Name for choice in Choice.Options track by choice.ID">
</select>

If you need to manipulate it on the client side, you can't use the Visible property on the server side. Instead, set its CSS display style to "none". For example:

<asp:Label runat="server" id="Label1" style="display: none;" />

Then, you could make it visible on the client side with:

document.getElementById('Label1').style.display = 'inherit';

You could make it hidden again with:

document.getElementById('Label1').style.display = 'none';

Keep in mind that there may be issues with the ClientID being more complex than "Label1" in practice. You'll need to use the ClientID with getElementById, not the server side ID, if they differ.

This issue should be fixed in the newest version of Homebrew. Try reinstalling it, which is described on the Homebrew home page.

It's there to enforce some initialization logic required by all implementations of your abstract class, or any methods you have implemented on your abstract class (not all the methods on your abstract class have to be abstract, some can be implemented).

Any class which inherits from your abstract base class will be obliged to call the base constructor.

It depends on the List implementation. Since you index arrays with ints, an ArrayList can't hold more than Integer.MAX_VALUE elements. A LinkedList isn't limited in the same way, though, and can contain any amount of elements.

Make sure to check dynamic web app in "other section" i.e File>New>Other>Web or type in "dynamic web app" in your wizard filter. If dynamic web app is not there then follow following steps:

1. On Eclipse Menu Select HELP > INSTALL NEW SOFTWARE
2. In work with test box simply type in your eclipse version, which is oxygen in my case
3. Once you type in yur version something like this "Oxygen - http://download.eclipse.org/releases/oxygen"will be recommended to you in drop down
4. If you do not get any recommendation then simply copy " http://download.eclipse.org/releases/your-version" and paste it. Make sure to edit your-version.
5. After you Enter the address and press enter bunch of new softwares will be listed just ubderneath work with text box.
6. Scroll, find and Expand WEB, XML, Java EE .... tab
7. Select only these three options: Eclipse Java EE Developer Tools, Eclipse Java Web Developer Tools,Eclipse Web Developer Tools
8. Next, next and finish!

You can use map :

List<String> names = 
    personList.stream()
              .map(Person::getName)
              .collect(Collectors.toList());

EDIT :

In order to combine the Lists of friend names, you need to use flatMap :

List<String> friendNames = 
    personList.stream()
              .flatMap(e->e.getFriends().stream())
              .collect(Collectors.toList());

    {
        InitializeComponent();

Just Found 3 simple steps to alter already existing column that was null before

update   orders
set BasicHours=0 where BasicHours is null

alter table orders 
add default(0) for BasicHours

alter table orders 
alter  column CleanBasicHours decimal(7,2) not null 

You can also do Object.values(example)[0].

If you're working with an x64 server, keep in mind that there are different ODBC settings for x86 and x64 applications. The "Data Sources (ODBC)" tool in the Administrative Tools list takes you to the x64 version. To view/edit the x86 ODBC settings, you'll need to run that version of the tool manually:

%windir%\SysWOW64\odbcad32.exe (%windir% is usually C:\Windows)

When your app runs as x64, it will use the x64 data sources, and when it runs as x86, it will use those data sources instead.

I was looking for the same funcionality and found this answer. However, I wanted to give you guys a quick update. It's CSS3's vmin unit.

p, li
{
  font-size: 1.2vmin;
}

vmin means 'whichever is smaller between the 1% of the ViewPort's height and the 1% of the ViewPort's width'.

MongoDB needs data directory to store data. Default path is /data/db

When you start MongoDB engine, it searches this directory which is missing in your case. Solution is create this directory and assign rwx permission to user.

If you want to change the path of your data directory then you should specify it while starting mongod server like,

mongod --dbpath /data/<path> --port <port no> 

This should help you start your mongod server with custom path and port.

As for second question - you can use Fiddler filters to set response X-Frame-Options header manually to something like ALLOW-FROM *. But, of course, this trick will work only for you - other users still won't be able to see iframe content(if they not do the same).

To answer to your second question. You can just hit the IP address of the machine that your flask app is running, e.g. 192.168.1.100 in a browser on different machine on the same network and you are there. Though, you will not be able to access it if you are on a different network. Firewalls or VLans can cause you problems with reaching your application. If that computer has a public IP, then you can hit that IP from anywhere on the planet and you will be able to reach the app. Usually this might impose some configuration, since most of the public servers are behind some sort of router or firewall.

How about a solution where you put the actual "data" of the table inside its own div, with overflow: scroll;? Then the browser will automatically create scrollbars for the portion of the "table" you do not want to lock, and you can put the "table header"/first row just above that <div>.

Not sure how that would work with scrolling horizontally though.

Seem this bug is not fixed yet [1]. Some people get worked, some people not. I also get not worked.

In 1.0 you should use:

io.sockets.connected[socketid].emit();

I used to have the same problem. I could not find anything that would help me so I ended up making the class PrintTable--code below. There is also an output. The usage is simple:

ptobj = PrintTable(yourdata, column_captions, column_widths, text_aligns)
ptobj.print()

or in one line:

PrintTable(yourdata, column_captions, column_widths, text_aligns).print()

IMPORTANT: <button> should never be a descendent of <a>.

Try <a href="http://stackoverflow.com"><button>Link Text</button></a> in any html validator like https://validator.w3.org and you'll get an error. There's really no point in using a button if you're not using the button. Just style the <a> with css to look like a button. If you're using a framework like Bootstrap, you could apply the button style(s) btn, btn-primary etc.

This error means that you have not specified your remote URL location upon which your code will push.

You can set remote URL by 2 (mainly) ways:

1. Specify remote URL via executing command on Git Bash.

   • Navigate to your project directory

   • Open Git Bash

   • Execute command:

     • git remote set-url origin <https://abc.xyz/USERNAME/REPOSITORY.git>

2. Mention remote URL direct in config file

   • Navigate to your project directory

   • Move to .git folder

   • Open config file in text editor

   • Copy and paste below lines

     • [remote "origin"] url = https://abc.xyz/USERNAME/REPOSITORY.git fetch = +refs/heads/*:refs/remotes/origin/*

Is there also a way to invoke this feature (which based on answers is called the Task Scheduler) programatically [...]?

I prefer not to use a prefix on interfaces:

• The prefix hurts readability.

• Using interfaces in clients is the standard best way to program, so interfaces names should be as short and pleasant as possible. Implementing classes should be uglier to discourage their use.

• When changing from an abstract class to an interface a coding convention with prefix I implies renaming all the occurrences of the class --- not good!

Primary key attributes are just as updateable as any other attributes of a table. Stability is often a desirable property of a key but definitely not an absolute requirement. If it makes sense from a business perpective to update a key then there's no fundamental reason why you shouldn't.

I think the error because the elements are undefined ,so you need to add window.onload event which this event will defined your elements when the window is loaded.

window.addEventListener('load',Loaded,false);


    function Loaded(){
    var myButton = document.getElementById("myButton");
    var myTextfield = document.getElementById("myTextfield");

    function greetUser(userName) {
    var greeting = "Hello " + userName + "!";
    document.getElementsByTagName ("h2")[0].innerHTML = greeting;
    }

    myButton.onclick = function() {
    var userName = myTextfield.value;
    greetUser(userName);

    return false;
    }
    }

PUT /testIndex
{
    "mappings": {
        "properties": {     <--ADD THIS
            "field1": {
                "type": "integer"
            },
            "field2": {  
                "type": "integer"
            },
            "field3": {

                "index": "not_analyzed"
            },
            "field4": {
                "type": "string",

        }
    },
    "settings": {
        bla
        bla
        bla
    }
}

Here's a similar command I know works:

curl -v -H "Content-Type: application/json" -H "Authorization: Basic cGC3COJ1c2Vy925hZGFJbXBvcnABCnRl" -X PUT -d '{"mappings":{"properties":{"city":{"type": "text"}}}}' https://35.80.2.21/manzanaIndex

The breakdown for the above curl command is:

PUT /manzanaIndex
{
    "mappings":{
        "properties":{
                "city":{
                    "type": "text"
                }
        }
    }
}

If SQL Server edition is 2005/2008, you can use DMVs to calculate the row count in a table:

-- Shows all user tables and row counts for the current database 
-- Remove is_ms_shipped = 0 check to include system objects 
-- i.index_id < 2 indicates clustered index (1) or hash table (0) 
SELECT o.name, 
 ddps.row_count 
FROM sys.indexes AS i 
 INNER JOIN sys.objects AS o ON i.OBJECT_ID = o.OBJECT_ID 
 INNER JOIN sys.dm_db_partition_stats AS ddps ON i.OBJECT_ID = ddps.OBJECT_ID 
 AND i.index_id = ddps.index_id 
WHERE i.index_id < 2 
 AND o.is_ms_shipped = 0 
ORDER BY o.NAME 

For SQL Server 2000 database engine, sysindexes will work, but it is strongly advised to avoid using it in future editions of SQL Server as it may be removed in the near future.

Node v8.5.0+

You don't need JSON loader. Node provides ECMAScript Modules (ES6 Module support) with the --experimental-modules flag, you can use it like this

node --experimental-modules myfile.mjs

Then it's very simple

import myJSON from './myJsonFile.json';
console.log(myJSON);

Then you'll have it bound to the variable myJSON.

Use CURRENT_TIMESTAMP() or now()

Like

INSERT INTO servers (server_name, online_status, exchange, disk_space,
network_shares,date_time) VALUES('m1','ONLINE','ONLINE','100GB','ONLINE',now() )

or

INSERT INTO servers (server_name, online_status, exchange, disk_space,
network_shares,date_time) VALUES('m1', 'ONLINE', 'ONLINE', '100GB', 'ONLINE'
,CURRENT_TIMESTAMP() )

Replace date_time with the column name you want to use to insert the time.

There are many tools that will make this easy. See monjardin's answer for more details about what's involved.

However, doing this isn't necessarily difficult. It sounds like you're using Java, so I would recommend looking into something like GDAL. It provides java wrappers for their routines, and they have all the tools required to convert from Lat/Lon (geographic coordinates) to UTM (projected coordinate system) or some other reasonable map projection.

UTM is nice, because it's meters, so easy to work with. However, you will need to get the appropriate UTM zone for it to do a good job. There are some simple codes available via googling to find an appropriate zone for a lat/long pair.

We were able to solve a similar issue here using Oracle LISTAGG. There was a point where what we were grouping on exceeded the 4K limit but this was easily solved by having the first dataset take the first 15 items to aggregate, each of which have a 256K limit.

More info: We have projects, which have change orders, which in turn have explanations. Why the database is set up to take change text in chunks of 256K limits is not known but its one of the design constraints. So the application that feeds change explanations into the table stops at 254K and inserts, then gets the next set of text and if > 254K generates another row, etc. So we have a project to a change order, a 1:1. Then we have these as 1:n for explanations. LISTAGG concatenates all these. We have RMRKS_SN values, 1 for each remark and/or for each 254K of characters.

The largest RMRKS_SN was found to be 31, so I did the first dataset pulling SN 0 to 15, the 2nd dataset 16 to 30 and the last dataset 31 to 45 -- hey, let's plan on someone adding a LOT of explanation to some change orders!

In the SQL report, the Tablix ties to the first dataset. To get the other data, here's the expression:

=First(Fields!NON_STD_TXT.Value, "DataSet_EXPLAN") & First(Fields!NON_STD_TXT.Value, "ds_EXPLAN_SN_16_TO_30") & First(Fields!NON_STD_TXT.Value, "ds_EXPLAN_SN_31_TO_45")

For us, we have to have DB Group create functions, etc. because of security constraints. So with a bit of creativity, we didn't have to do a User Aggregate or a UDF.

If your application has some sort of SN to aggregate by, this method should work. I don't know what the equivalent TSQL is -- we're fortunate to be dealing with Oracle for this report, for which LISTAGG is a Godsend.

The code is:

SELECT
LT.C_O_NBR AS LT_CO_NUM,
RT.C_O_NBR AS RT_CO_NUM,
LT.STD_LN_ITM_NBR, 
RT.NON_STD_LN_ITM_NBR,
RT.NON_STD_PRJ_NBR, 
LT.STD_PRJ_NBR, 
NVL(LT.PRPSL_LN_NBR, RT.PRPSL_LN_NBR) AS PRPSL_LN_NBR,
LT.STD_CO_EXPL_TXT AS STD_TXT,
LT.STD_CO_EXPLN_T, 
LT.STD_CO_EXPL_SN, 
RT.NON_STD_CO_EXPLN_T,
LISTAGG(RT.RMRKS_TXT_FLD, '') 
    WITHIN GROUP(ORDER BY RT.RMRKS_SN) AS NON_STD_TXT

FROM ...

    WHERE RT.RMRKS_SN BETWEEN 0 AND 15

GROUP BY 
    LT.C_O_NBR,
    RT.C_O_NBR,
    ...

And in the other 2 datasets just select the LISTAGG only for the subqueries in the FROM:

SELECT
LISTAGG(RT.RMRKS_TXT_FLD, '') 
    WITHIN GROUP(ORDER BY RT.RMRKS_SN) AS NON_STD_TXT

FROM ...

WHERE RT.RMRKS_SN BETWEEN 31 AND 45

...

... and so on.

Microsoft gave a good example of doing this:

https://docs.microsoft.com/en-us/aspnet/web-api/overview/advanced/sending-html-form-data-part-1

First validate the request

if (ModelState.IsValid)

and than use the serialized data.

Content = new StringContent(update.Status)

Here 'Status' is a field in the complex type. Serializing is done by .NET, no need to worry about that.

Handy way: Using Browser Printing/Preview

1. Hide editor pane
2. Print Preview (I used firefox, others also fine)
3. Change its page setup and print to pdf

Using a cookie to provide the CSRF token to the client does not allow a successful attack because the attacker cannot read the value of the cookie and therefore cannot put it where the server-side CSRF validation requires it to be.

The attacker will be able to cause a request to the server with both the auth token cookie and the CSRF cookie in the request headers. But the server is not looking for the CSRF token as a cookie in the request headers, it's looking in the payload of the request. And even if the attacker knows where to put the CSRF token in the payload, they would have to read its value to put it there. But the browser's cross-origin policy prevents reading any cookie value from the target website.

The same logic does not apply to the auth token cookie, because the server is expects it in the request headers and the attacker does not have to do anything special to put it there.

Your model is null because the way you're supplying the inputs to your form means the model binder has no way to distinguish between the elements. Right now, this code:

@foreach (var planVM in Model)
{
    @Html.Partial("_partialView", planVM)
}

is not supplying any kind of index to those items. So it would repeatedly generate HTML output like this:

<input type="hidden" name="yourmodelprefix.PlanID" />
<input type="hidden" name="yourmodelprefix.CurrentPlan" />
<input type="checkbox" name="yourmodelprefix.ShouldCompare" />

However, as you're wanting to bind to a collection, you need your form elements to be named with an index, such as:

<input type="hidden" name="yourmodelprefix[0].PlanID" />
<input type="hidden" name="yourmodelprefix[0].CurrentPlan" />
<input type="checkbox" name="yourmodelprefix[0].ShouldCompare" />
<input type="hidden" name="yourmodelprefix[1].PlanID" />
<input type="hidden" name="yourmodelprefix[1].CurrentPlan" />
<input type="checkbox" name="yourmodelprefix[1].ShouldCompare" />

That index is what enables the model binder to associate the separate pieces of data, allowing it to construct the correct model. So here's what I'd suggest you do to fix it. Rather than looping over your collection, using a partial view, leverage the power of templates instead. Here's the steps you'd need to follow:

1. Create an EditorTemplates folder inside your view's current folder (e.g. if your view is Home\Index.cshtml, create the folder Home\EditorTemplates).
2. Create a strongly-typed view in that directory with the name that matches your model. In your case that would be PlanCompareViewModel.cshtml.

Now, everything you have in your partial view wants to go in that template:

@model PlanCompareViewModel
<div>
    @Html.HiddenFor(p => p.PlanID)
    @Html.HiddenFor(p => p.CurrentPlan)
    @Html.CheckBoxFor(p => p.ShouldCompare)
   <input type="submit" value="Compare"/>
</div>

Finally, your parent view is simplified to this:

@model IEnumerable<PlanCompareViewModel>
@using (Html.BeginForm("ComparePlans", "Plans", FormMethod.Post, new { id = "compareForm" }))
{
<div>
    @Html.EditorForModel()
</div>
}

DisplayTemplates and EditorTemplates are smart enough to know when they are handling collections. That means they will automatically generate the correct names, including indices, for your form elements so that you can correctly model bind to a collection.

I am using the following code to write vertical text in a page. Firefox 3.5+, webkit, opera 10.5+ and IE

.rot-neg-90 {
    -moz-transform:rotate(-270deg); 
    -moz-transform-origin: bottom left;
    -webkit-transform: rotate(-270deg);
    -webkit-transform-origin: bottom left;
    -o-transform: rotate(-270deg);
    -o-transform-origin:  bottom left;
    filter: progid:DXImageTransform.Microsoft.BasicImage(rotation=1);
}

You're forgetting to read it as binary too.

In your write part you have:

open(b"Fruits.obj","wb") # Note the wb part (Write Binary)

In the read part you have:

file = open("Fruits.obj",'r') # Note the r part, there should be a b too

So replace it with:

file = open("Fruits.obj",'rb')

And it will work :)

As for your second error, it is most likely cause by not closing/syncing the file properly.

Try this bit of code to write:

>>> import pickle
>>> filehandler = open(b"Fruits.obj","wb")
>>> pickle.dump(banana,filehandler)
>>> filehandler.close()

And this (unchanged) to read:

>>> import pickle
>>> file = open("Fruits.obj",'rb')
>>> object_file = pickle.load(file)

A neater version would be using the with statement.

For writing:

>>> import pickle
>>> with open('Fruits.obj', 'wb') as fp:
>>>     pickle.dump(banana, fp)

For reading:

>>> import pickle
>>> with open('Fruits.obj', 'rb') as fp:
>>>     banana = pickle.load(fp)

Try to keep your state minimal. There is no need to store

   const initialValue = [
    { id: 0,value: " --- Select a State ---" }];

as state. Separate the permanent from the changing

const ALL_STATE_VALS = [
    { id: 0,value: " --- Select a State ---" }
    { id: 1, value: "Alabama" },
    { id: 2, value: "Georgia" },
    { id: 3, value: "Tennessee" }
];

Then you can store just the id as your state:

const StateSelector = () =>{
  const [selectedStateOption, setselectedStateOption] = useState(0);

  return (
    <div>
      <label>Select a State:</label>
      <select>
        {ALL_STATE_VALS.map((option, index) => (
          <option key={option.id} selected={index===selectedStateOption}>{option.value}</option>
        ))}
      </select>
    </div>);
   )
}

I don't use Gradle in anger myself (just a toy project so far) [author means they have used Gradle on only a toy project so far, not that Gradle is a toy project - see comments], but I'd say that the reasons one would consider using it would be because of the frustrations of Ant and Maven.

In my experience Ant is often write-only (yes I know it is possible to write beautifully modular, elegant builds, but the fact is most people don't). For any non-trivial projects it becomes mind-bending, and takes great care to ensure that complex builds are truly portable. Its imperative nature can lead to replication of configuration between builds (though macros can help here).

Maven takes the opposite approach and expects you to completely integrate with the Maven lifecycle. Experienced Ant users find this particularly jarring as Maven removes many of the freedoms you have in Ant. For example there's a Sonatype blog that enumerates many of the Maven criticisms and their responses.

The Maven plugin mechanism allows for very powerful build configurations, and the inheritance model means you can define a small set of parent POMs encapsulating your build configurations for the whole enterprise and individual projects can inherit those configurations, leaving them lightweight. Maven configuration is very verbose (though Maven 3 promises to address this), and if you want to do anything that is "not the Maven way" you have to write a plugin or use the hacky Ant integration. Note I happen to like writing Maven plugins but appreciate that many will object to the effort involved.

Gradle promises to hit the sweet spot between Ant and Maven. It uses Ivy's approach for dependency resolution. It allows for convention over configuration but also includes Ant tasks as first class citizens. It also wisely allows you to use existing Maven/Ivy repositories.

So if you've hit and got stuck with any of the Ant/Maven pain points, it is probably worth trying Gradle out, though in my opinion it remains to be seen if you wouldn't just be trading known problems for unknown ones. The proof of the pudding is in the eating though so I would reserve judgment until the product is a little more mature and others have ironed out any kinks (they call it bleeding edge for a reason). I'll still be using it in my toy projects though, It's always good to be aware of the options.

I have tested this code working file:

var timeout = null;
    var timee = '4000'; // default time for session time out.
    $(document).bind('click keyup mousemove', function(event) {

    if (timeout !== null) {
            clearTimeout(timeout);
        }
        timeout = setTimeout(function() {
              timeout = null;
            console.log('Document Idle since '+timee+' ms');
            alert("idle window");
        }, timee);
    });

I think a nice solution is with the function filter of pandas and regex (match everything except "b"):

df.filter(regex="^(?!b$)")

I would use os.chdir like this:

os.chdir("/path/to/change/to")

By the way, if you need to figure out your current path, use os.getcwd().

If you want a version that raises an error:

If you want a version that returns -1:

"string to search".find("needle") 

This is more efficient than the 'in' syntax

A workaround and a handy tool:

CSS3Pie uses .htc files and the behavior property to implement CSS3 into IE 6 - 8.

Modernizr is a bit of javascript that will put classes on your html element, allowing you to serve different style definitions to different browsers based on their capabilities.

Obviously, these both add more overhead, but with IE9 due to only run on Vista/7 we might be stuck for quite awhile. As of August 2010 Windows XP still accounts for 48% of web client OSes.

I came here with a similar question/problem, but I only needed a single value to be stored from the query, not an array/table of results as in the orig post. I was able to use the table method above for a single value, however I have stumbled upon an easier way to store a single value.

declare @myVal int; set @myVal = isnull((select a from table1), 0);

Make sure to default the value in the isnull statement to a valid type for your variable, in my example the value in table1 that we're storing is an int.

Most languages have path parsing functions that will give you this already. If you have the ability, I'd recommend using what comes to you for free out-of-the-box.

Assuming / is the path delimiter...

^(.*/)([^/]*)$

The first group will be whatever the directory/path info is, the second will be the filename. For example:

• /foo/bar/baz.log: "/foo/bar/" is the path, "baz.log" is the file
• foo/bar.log: "foo/" is the path, "bar.log" is the file
• /foo/bar: "/foo/" is the path, "bar" is the file
• /foo/bar/: "/foo/bar/" is the path and there is no file.

You only need to force cscript instead wscript. I always use this template. The function ForceConsole() will execute your vbs into cscript, also you have nice alias to print and scan text.

 Set oWSH = CreateObject("WScript.Shell")
 vbsInterpreter = "cscript.exe"

 Call ForceConsole()

 Function printf(txt)
    WScript.StdOut.WriteLine txt
 End Function

 Function printl(txt)
    WScript.StdOut.Write txt
 End Function

 Function scanf()
    scanf = LCase(WScript.StdIn.ReadLine)
 End Function

 Function wait(n)
    WScript.Sleep Int(n * 1000)
 End Function

 Function ForceConsole()
    If InStr(LCase(WScript.FullName), vbsInterpreter) = 0 Then
        oWSH.Run vbsInterpreter & " //NoLogo " & Chr(34) & WScript.ScriptFullName & Chr(34)
        WScript.Quit
    End If
 End Function

 Function cls()
    For i = 1 To 50
        printf ""
    Next
 End Function

 printf " _____ _ _           _____         _    _____         _     _   "

var driver = new webdriver.Builder().usingServer('serverAddress').withCapabilities({'browserName': 'firefox'}).build();

driver.get('http://www.google.com');
driver.findElement(webdriver.By.id('gbqfb')).click();

Much easier way: use template literals.

var variable = 'foo'
var expression = `.*${variable}.*`
var re = new RegExp(expression, 'g')
re.test('fdjklsffoodjkslfd') // true
re.test('fdjklsfdjkslfd') // false

Instead of typing each time, you can;

[1] Create a generic print method inside Spark Shell.

def p(rdd: org.apache.spark.rdd.RDD[_]) = rdd.foreach(println)

[2] Or even better, using implicits, you can add the function to RDD class to print its contents.

implicit class Printer(rdd: org.apache.spark.rdd.RDD[_]) {
    def print = rdd.foreach(println)
}

Example usage:

val rdd = sc.parallelize(List(1,2,3,4)).map(_*2)

p(rdd) // 1
rdd.print // 2

Output:

2
6
4
8

This only makes sense if you are working in local mode and with a small amount of data set. Otherwise, you either will not be able to see the results on the client or run out of memory because of the big dataset result.

if your using jellybean just start cmd, type adb devices to make sure your readable, type adb pull sdcard/ sdcard_(the date or extra) <---this file needs to be made in adb directory beforehand. PROFIT!

In other versions type adb pull mnt/sdcard/ sdcard_(the date or extra)

Remember to make file or your either gonna have a mess or it wont work.

Sometime some C# approach makes the life easier in Java world..:

class XLINK {
static final short PAYLOAD = 102, ACK = 103, PAYLOAD_AND_ACK = 104;
}
//Now is trivial to use it like a C# enum:
int rcv = XLINK.ACK;

there's also ndisasm, which has some quirks, but can be more useful if you use nasm. I agree with Michael Mrozek that objdump is probably best.

[later] you might also want to check out Albert van der Horst's ciasdis: http://home.hccnet.nl/a.w.m.van.der.horst/forthassembler.html. it can be hard to understand, but has some interesting features you won't likely find anywhere else.

You can apply dirname repeatedly to climb higher: dirname(dirname(file)). This can only go as far as the root package, however. If this is a problem, use os.path.abspath: dirname(dirname(abspath(file))).

No, it is not possible.

Consider a scenario where an ACBus is a derived class of base class Bus. ACBus has features like TurnOnAC and TurnOffAC which operate on a field named ACState. TurnOnAC sets ACState to on and TurnOffAC sets ACState to off. If you try to use TurnOnAC and TurnOffAC features on Bus, it makes no sense.

You could do something like this:

$("span, p").each(function() {
    var text = $(this).text();
    text = text.replace("lollypops", "marshmellows");
    $(this).text(text);
});

It will be better to mark all tags with text that needs to be examined with a suitable class name.

Also, this may have performance issues. jQuery or javascript in general aren't really suitable for this kind of operations. You are better off doing it server side.

Or you can try ignoreElements() as well

Using dplyr:

library(dplyr)

# exclude ID column then get mean
DF %>%
  transmute(ID,
            Mean = rowMeans(select(., -ID)))

Or

# select the columns to include in mean
DF %>%
  transmute(ID,
            Mean = rowMeans(select(., C1:C3)))

#   ID     Mean
# 1  A 3.666667
# 2  B 4.333333
# 3  C 3.333333
# 4  D 4.666667
# 5  E 4.333333

An abstract class is a class that can't be instantiated. It's only purpose is for other classes to extend.

Abstract methods are methods in the abstract class (have to be declared abstract) which means the extending concrete class must override them as they have no body.

The main purpose of an abstract class is if you have common code to use in sub classes but the abstract class should not have instances of its own.

You can read more about it here: Abstract Methods and Classes

json.dumps() is used to decode JSON data

Array slicing like in Python (From the rebash library):

array_slice() {
    local __doc__='
    Returns a slice of an array (similar to Python).

    From the Python documentation:
    One way to remember how slices work is to think of the indices as pointing
    between elements, with the left edge of the first character numbered 0.
    Then the right edge of the last element of an array of length n has
    index n, for example:
    ```
    +---+---+---+---+---+---+
    | 0 | 1 | 2 | 3 | 4 | 5 |
    +---+---+---+---+---+---+
    0   1   2   3   4   5   6
    -6  -5  -4  -3  -2  -1
    ```

    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice 1:-2 "${a[@]}")
    1 2 3
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice 0:1 "${a[@]}")
    0
    >>> local a=(0 1 2 3 4 5)
    >>> [ -z "$(array.slice 1:1 "${a[@]}")" ] && echo empty
    empty
    >>> local a=(0 1 2 3 4 5)
    >>> [ -z "$(array.slice 2:1 "${a[@]}")" ] && echo empty
    empty
    >>> local a=(0 1 2 3 4 5)
    >>> [ -z "$(array.slice -2:-3 "${a[@]}")" ] && echo empty
    empty
    >>> [ -z "$(array.slice -2:-2 "${a[@]}")" ] && echo empty
    empty

    Slice indices have useful defaults; an omitted first index defaults to
    zero, an omitted second index defaults to the size of the string being
    sliced.
    >>> local a=(0 1 2 3 4 5)
    >>> # from the beginning to position 2 (excluded)
    >>> echo $(array.slice 0:2 "${a[@]}")
    >>> echo $(array.slice :2 "${a[@]}")
    0 1
    0 1

    >>> local a=(0 1 2 3 4 5)
    >>> # from position 3 (included) to the end
    >>> echo $(array.slice 3:"${#a[@]}" "${a[@]}")
    >>> echo $(array.slice 3: "${a[@]}")
    3 4 5
    3 4 5

    >>> local a=(0 1 2 3 4 5)
    >>> # from the second-last (included) to the end
    >>> echo $(array.slice -2:"${#a[@]}" "${a[@]}")
    >>> echo $(array.slice -2: "${a[@]}")
    4 5
    4 5

    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice -4:-2 "${a[@]}")
    2 3

    If no range is given, it works like normal array indices.
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice -1 "${a[@]}")
    5
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice -2 "${a[@]}")
    4
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice 0 "${a[@]}")
    0
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice 1 "${a[@]}")
    1
    >>> local a=(0 1 2 3 4 5)
    >>> array.slice 6 "${a[@]}"; echo $?
    1
    >>> local a=(0 1 2 3 4 5)
    >>> array.slice -7 "${a[@]}"; echo $?

$.widget( "ui.dialog", $.ui.dialog, {_x000D_
 open: function() {_x000D_
  $(this.uiDialogTitlebarClose)_x000D_
   .html("<span class='ui-button-icon-primary ui-icon ui-icon-closethick'></span><span class='ui-button-text'>close</span>");_x000D_
  // Invoke the parent widget's open()._x000D_
  return this._super();_x000D_
 }_x000D_
});

-(void)showAlert{

    UIAlertController* alert = [UIAlertController alertControllerWithTitle:@"Title"
                                                                   message:"Message"

Watch out for certain headers such as HTTP_X_FORWARDED_FOR that appear to contain a single IP address. They may actually contain multiple addresses (a chain of proxies I assume).

They will appear to be comma delimited - and can be a lot longer than 45 characters total - so check before storing in DB.

That’s a typo. You’ve accidently set user.mail with no e. Fix it by setting user.email in the global configuration with

git config --global user.email "[email protected]"

Yes, NSDictionary supports fast enumeration. With Objective-C 2.0, you can do this:

// To print out all key-value pairs in the NSDictionary myDict
for(id key in myDict)
    NSLog(@"key=%@ value=%@", key, [myDict objectForKey:key]);

The alternate method (which you have to use if you're targeting Mac OS X pre-10.5, but you can still use on 10.5 and iPhone) is to use an NSEnumerator:

NSEnumerator *enumerator = [myDict keyEnumerator];
id key;
// extra parens to suppress warning about using = instead of ==
while((key = [enumerator nextObject]))
    NSLog(@"key=%@ value=%@", key, [myDict objectForKey:key]);

I found this to be more cross-browser compatible:

$(document).keypress(function(event) {
    var keycode = event.keyCode || event.which;
    if(keycode == '13') {
        alert('You pressed a "enter" key in somewhere');    
    }
});

I haven't tried it yet, but pyiso8601 promises to support this.

The simplest way is to edit .git/config

Here is an example file

[core]
        repositoryformatversion = 0
        filemode = true
        bare = false
        logallrefupdates = true
        ignorecase = true
[remote "origin"]
        url = [email protected]:repo-name
        fetch = +refs/heads/*:refs/remotes/origin/*
[branch "test1"]
        remote = origin
        merge = refs/heads/test1
[branch "master"]
        remote = origin
        merge = refs/heads/master

Delete the line merge = refs/heads/test1 in the test1 branch section

The difference lies in the fact that ./gradlew indicates you are using a gradle wrapper. The wrapper is generally part of a project and it facilitates installation of gradle. If you were using gradle without the wrapper you would have to manually install it - for example, on a mac brew install gradle and then invoke gradle using the gradle command. In both cases you are using gradle, but the former is more convenient and ensures version consistency across different machines.

Each Wrapper is tied to a specific version of Gradle, so when you first run one of the commands above for a given Gradle version, it will download the corresponding Gradle distribution and use it to execute the build.

Not only does this mean that you don’t have to manually install Gradle yourself, but you are also sure to use the version of Gradle that the build is designed for. This makes your historical builds more reliable

Read more here - https://docs.gradle.org/current/userguide/gradle_wrapper.html

Also, Udacity has a neat, high level video explaining the concept of the gradle wrapper - https://www.youtube.com/watch?v=1aA949H-shk

Here is another way to reproduce this error in Python2.7 with numpy:

import numpy as np
a = np.array([1,2,3])
b = np.array([4,5,6])
c = np.concatenate(a,b)   #note the lack of tuple format for a and b
print(c) 

The np.concatenate method produces an error:

TypeError: only length-1 arrays can be converted to Python scalars

If you read the documentation around numpy.concatenate, then you see it expects a tuple of numpy array objects. So surrounding the variables with parens fixed it:

import numpy as np
a = np.array([1,2,3])
b = np.array([4,5,6])
c = np.concatenate((a,b))  #surround a and b with parens, packaging them as a tuple
print(c) 

Then it prints:

[1 2 3 4 5 6]

What's going on here?

That error is a case of bubble-up implementation - it is caused by duck-typing philosophy of python. This is a cryptic low-level error python guts puke up when it receives some unexpected variable types, tries to run off and do something, gets part way through, the pukes, attempts remedial action, fails, then tells you that "you can't reformulate the subspace responders when the wind blows from the east on Tuesday".

In more sensible languages like C++ or Java, it would have told you: "you can't use a TypeA where TypeB was expected". But Python does it's best to soldier on, does something undefined, fails, and then hands you back an unhelpful error. The fact we have to be discussing this is one of the reasons I don't like Python, or its duck-typing philosophy.

This is easy to do, you can render the report as a PDF, and save the resulting byte array as a PDF file on disk. To do this in the background, that's more a question of how your app is written. You can just spin up a new thread, or use a BackgroundWorker (if this is a WinForms app), etc. There, of course, may be multithreading issues to be aware of.

Warning[] warnings;
string[] streamids;
string mimeType;
string encoding;
string filenameExtension;

byte[] bytes = reportViewer.LocalReport.Render(
    "PDF", null, out mimeType, out encoding, out filenameExtension,
    out streamids, out warnings);

using (FileStream fs = new FileStream("output.pdf", FileMode.Create))
{
    fs.Write(bytes, 0, bytes.Length);
}

Set the class .fill to height: 100%

.fill { 
    min-height: 100%;
    height: 100%;
}

JSFiddle

(I put a red background for #map so you can see it takes up 100% height)

$('#myDiv').children().each( (index, element) => {
    console.log(index);     // children's index
    console.log(element);   // children's element
 });

This iterates through all the children and their element with index value can be accessed separately using element and index respectively.

here is simple code

List <String> list = new ArrayList <String>();
list.add("a");
list.add("b");
JSONArray array = new JSONArray();
for (int i = 0; i < list.size(); i++) {
        array.put(list.get(i));
}
JSONObject obj = new JSONObject();
try {
    obj.put("result", array);
} catch (JSONException e) {
 // TODO Auto-generated catch block
e.printStackTrace();
}
pw.write(obj.toString());

Placing @EdChum's very nice answer into a function count_unique_index. The unique method only works on pandas series, not on data frames. The function below reproduces the behavior of the unique function in R:

unique returns a vector, data frame or array like x but with duplicate elements/rows removed.

And adds a count of the occurrences as requested by the OP.

df1 = pd.DataFrame({'A':['yes','yes','yes','yes','no','no','yes','yes','yes','no'],                                                                                             
                    'B':['yes','no','no','no','yes','yes','no','yes','yes','no']})

Ran into the same problem myself, but my controller definitions looked a little different than above. For controllers defined like this:

function MyController($scope, $http) {
    // ...
}

Just add a line after the declaration indicating which objects to inject when the controller is instantiated:

function MyController($scope, $http) {
    // ...
}
MyController.$inject = ['$scope', '$http'];

This makes it minification-safe.

You essentially do inherit the constuctors in the sense that you can simply call super if and when appropriate, it's just that it would be error prone for reasons others have mentioned if it happened by default. The compiler can't presume when it is appropriate and when it isn't.

The job of the compiler is to provide as much flexibility as possible while reducing complexity and risk of unintended side-effects.

Please look at http://www.tldp.org/LDP/abs/html/parameter-substitution.html for examples

${parameter-default}, ${parameter:-default}

If parameter not set, use default. After the call, parameter is still not set.
Both forms are almost equivalent. The extra : makes a difference only when parameter has been declared, but is null.

unset EGGS
echo 1 ${EGGS-spam}   # 1 spam
echo 2 ${EGGS:-spam}  # 2 spam

EGGS=
echo 3 ${EGGS-spam}   # 3
echo 4 ${EGGS:-spam}  # 4 spam

EGGS=cheese
echo 5 ${EGGS-spam}   # 5 cheese
echo 6 ${EGGS:-spam}  # 6 cheese

${parameter=default}, ${parameter:=default}

If parameter not set, set parameter value to default.
Both forms nearly equivalent. The : makes a difference only when parameter has been declared and is null

# sets variable without needing to reassign
# colons suppress attempting to run the string
unset EGGS
: ${EGGS=spam}
echo 1 $EGGS     # 1 spam
unset EGGS
: ${EGGS:=spam}
echo 2 $EGGS     # 2 spam

EGGS=
: ${EGGS=spam}
echo 3 $EGGS     # 3        (set, but blank -> leaves alone)
EGGS=
: ${EGGS:=spam}
echo 4 $EGGS     # 4 spam

EGGS=cheese
: ${EGGS:=spam}
echo 5 $EGGS     # 5 cheese
EGGS=cheese
: ${EGGS=spam}
echo 6 $EGGS     # 6 cheese

${parameter+alt_value}, ${parameter:+alt_value}

If parameter set, use alt_value, else use null string. After the call, parameter value not changed.
Both forms nearly equivalent. The : makes a difference only when parameter has been declared and is null

unset EGGS
echo 1 ${EGGS+spam}  # 1
echo 2 ${EGGS:+spam} # 2

I think the order has to do with the way the files are indexed on your FileSystem. If you really want to make it adhere to some order you can always sort the list after getting the files.

remove the ios::binary from your modes in your ofstream and use studentPassword.c_str() instead of (char *)&studentPassword in your write.write()

You want to convert html (a byte-like object) into a string using .decode, e.g. html = response.read().decode('utf-8').

Like you say, os.path.join joins paths based on the current os. posixpath is the underlying module that is used on posix systems under the namespace os.path:

>>> os.path.join is posixpath.join
True
>>> posixpath.join('/media/', 'js/foo.js')
'/media/js/foo.js'

So you can just import and use posixpath.join instead for urls, which is available and will work on any platform.

Edit: @Pete's suggestion is a good one, you can alias the import for increased readability

from posixpath import join as urljoin

Edit: I think this is made clearer, or at least helped me understand, if you look into the source of os.py (the code here is from Python 2.7.11, plus I've trimmed some bits). There's conditional imports in os.py that picks which path module to use in the namespace os.path. All the underlying modules (posixpath, ntpath, os2emxpath, riscospath) that may be imported in os.py, aliased as path, are there and exist to be used on all systems. os.py is just picking one of the modules to use in the namespace os.path at run time based on the current OS.

# os.py
import sys, errno

_names = sys.builtin_module_names

if 'posix' in _names:
    # ...
    from posix import *
    # ...
    import posixpath as path
    # ...

elif 'nt' in _names:
    # ...
    from nt import *
    # ...
    import ntpath as path
    # ...

elif 'os2' in _names:
    # ...
    from os2 import *
    # ...
    if sys.version.find('EMX GCC') == -1:
        import ntpath as path
    else:
        import os2emxpath as path
        from _emx_link import link
    # ...

elif 'ce' in _names:
    # ...
    from ce import *
    # ...
    # We can use the standard Windows path.
    import ntpath as path

elif 'riscos' in _names:
    # ...
    from riscos import *
    # ...
    import riscospath as path
    # ...

else:
    raise ImportError, 'no os specific module found'

We actually had these merged together originally, i.e. there was a "filter"-like method that accepted *args and **kwargs, where you could pass a SQL expression or keyword arguments (or both). I actually find that a lot more convenient, but people were always confused by it, since they're usually still getting over the difference between column == expression and keyword = expression. So we split them up.

This is due to sometimes the session query may have invalid characters, try clicking on the highlighted icons in PHPMYADMIN, and it will be resolved, because session values resetted to defaults See Image

A really dumb answer (I'll vote myself down in a minute), but this worked for me:

After adding your pipe, if you're still getting the errors and are running your Angular site using "ng serve", stop it... then start it up again.

For me, none of the other suggestions worked, but simply stopping, then restarting "ng serve" was enough to make the error go away.

Content inside a <div class='html-content'>....</div> can be downloaded as pdf with styles using jspdf & html2canvas.

You need to refer both js libraries,

<script type="text/javascript" src="https://html2canvas.hertzen.com/dist/html2canvas.js"></script>

Then call below function,

//Create PDf from HTML...
function CreatePDFfromHTML() {
    var HTML_Width = $(".html-content").width();
    var HTML_Height = $(".html-content").height();
    var top_left_margin = 15;
    var PDF_Width = HTML_Width + (top_left_margin * 2);
    var PDF_Height = (PDF_Width * 1.5) + (top_left_margin * 2);
    var canvas_image_width = HTML_Width;
    var canvas_image_height = HTML_Height;

    var totalPDFPages = Math.ceil(HTML_Height / PDF_Height) - 1;

    html2canvas($(".html-content")[0]).then(function (canvas) {
        var imgData = canvas.toDataURL("image/jpeg", 1.0);
        var pdf = new jsPDF('p', 'pt', [PDF_Width, PDF_Height]);
        pdf.addImage(imgData, 'JPG', top_left_margin, top_left_margin, canvas_image_width, canvas_image_height);
        for (var i = 1; i <= totalPDFPages; i++) { 
            pdf.addPage(PDF_Width, PDF_Height);
            pdf.addImage(imgData, 'JPG', top_left_margin, -(PDF_Height*i)+(top_left_margin*4),canvas_image_width,canvas_image_height);
        }
        pdf.save("Your_PDF_Name.pdf");
        $(".html-content").hide();
    });
}

I had a case where I had to fetch the first result of a very big Cartesian product. And it would take ages despite I only wanted one item. The problem was that it had to iterate through many unwanted results before finding a correct one because of the order of the results. So if I had 10 lists of 50 elements and the first element of the two first lists were incompatible, it had to iterate through the Cartesian product of the last 8 lists despite that they would all get rejected.

This implementation enables to test a result before it includes one item from each list. So when I check that an element is incompatible with the already included elements from the previous lists, I immediately go to the next element of the current list rather than iterating through all products of the following lists.

No that is wrong. Arrays are special objects in Java. So it is like passing other objects where you pass the value of the reference, but not the reference itself. Meaning, changing the reference of an array in the called routine will not be reflected in the calling routine.

Your linker (ld) obviously doesn't like the order in which make arranges the GCC arguments so you'll have to change your Makefile a bit:

CC=gcc
CFLAGS=-Wall
LDFLAGS=-lm

.PHONY: all
all: client

.PHONY: clean
clean:
    $(RM) *~ *.o client

OBJECTS=client.o
client: $(OBJECTS)
    $(CC) $(CFLAGS) $(OBJECTS) -o client $(LDFLAGS)

In the line defining the client target change the order of $(LDFLAGS) as needed.

You need to use WITH ROLLBACK IMMEDIATE to boot other conections out with no regards to what or who is is already using it.

Most applications I've worked with use decimal to represent money. This is based on the assumption that the application will never be concerned with more than one currency.

This assumption may be based on another assumption, that the application will never be used in other countries with different currencies. I've seen cases where that proved to be false.

Now that assumption is being challenged in a new way: New currencies such as Bitcoin are becoming more common, and they aren't specific to any country. It's not unrealistic that an application used in just one country may still need to support multiple currencies.

Some people will say that creating or even using a type just for money is "gold plating," or adding extra complexity beyond the known requirements. I strongly disagree. The more ubiquitous a concept is within your domain, the more important it is to make a reasonable effort to use the correct abstraction up front. If you want to see complexity, try working in an application that used to use decimal and now there's an additional Currency property next to every decimal property.

If you use the wrong abstraction up front, replacing it later will be a hundred times more work. That means potentially introducing defects into existing code, and the best part is that those defects will likely involve amounts of money, transactions with money, or just anything with money.

And it's not that difficult to use something other than decimal. Google "nuget money type" and you'll see that numerous developers have created such abstractions (including me.) It's easy. It's as easy as using DateTime instead of storing a date in a string.

Probably you just needed this CSS rule:

This is a bit of an old question, but I thought I would contribute my 2 cents anyway since this thread came up in conversation today.

This doesn't exactly answer why is there no const? but how to make your classes immutable. (Unfortunately I have not enough reputation yet to post as a comment to the accepted answer)

The way to guarantee immutability on an object is to design your classes more carefully to be immutable. This requires a bit more care than a mutable class.

This goes back to Josh Bloch's Effective Java Item 15 - Minimize Mutability. If you haven't read the book, pick up a copy and read it over a few times I guarantee it will up your figurative "java game".

In item 15 Bloch suggest that you should limit the mutability of classes to ensure the object's state.

To quote the book directly:

An immutable class is simply a class whose instances cannot be modified. All of the information contained in each instance is provided when it is created and is fixed for the lifetime of the object. The Java platform libraries contain many immutable classes, including String, the boxed primitive classes, and BigInte- ger and BigDecimal. There are many good reasons for this: Immutable classes are easier to design, implement, and use than mutable classes. They are less prone to error and are more secure.

Bloch then describes how to make your classes immutable, by following 5 simple rules:

1. Don’t provide any methods that modify the object’s state (i.e., setters, aka mutators)
2. Ensure that the class can’t be extended (this means declaring the class itself as final).
3. Make all fields final.
4. Make all fields private.
5. Ensure exclusive access to any mutable components. (by making defensive copies of the objects)

For more details I highly recommend picking up a copy of the book.
