From the docs (note: MSDN is a handy resource when you want to know what things do!):

ExecuteScalar

Use the ExecuteScalar method to retrieve a single value (for example, an aggregate value) from a database. This requires less code than using the ExecuteReader method, and then performing the operations that you need to generate the single value using the data returned by a SqlDataReader.

ExecuteReader

Sends the CommandText to the Connection and builds a SqlDataReader.

... and from SqlDataReader ...

Provides a way of reading a forward-only stream of rows from a SQL Server database. This class cannot be inherited.

ExecuteNonQuery

You can use the ExecuteNonQuery to perform catalog operations (for example, querying the structure of a database or creating database objects such as tables), or to change the data in a database without using a DataSet by executing UPDATE, INSERT, or DELETE statements.

You can use IPython's Module: display to load the image. You can read more from the Doc.

from IPython.display import Image 
pil_img = Image(filename='data/empire.jpg')
display(pil_img)

updated

As OP's requirement is to use PIL, if you want to show inline image, you can use matplotlib.pyplot.imshow with numpy.asarray like this too:

from matplotlib.pyplot import imshow
import numpy as np
from PIL import Image

%matplotlib inline
pil_im = Image.open('data/empire.jpg', 'r')
imshow(np.asarray(pil_im))

If you only require a preview rather than an inline, you may just use show like this:

pil_im = Image.open('data/empire.jpg', 'r')
pil_im.show()

screen -X -S SCREENID kill

alternatively, you can use the following command

screen -S SCREENNAME -p 0 -X quit

You can view the list of the screen sessions by executing screen -ls

just do it:

$file=Get-Item "C:\temp\file.htm"
$file.Basename 
$file.Extension

Optional.ofNullable(label)
.map(String::trim)
.map(string -> !label.isEmpty)
.orElse(false)

OR

TextUtils.isNotBlank(label);

the last solution will check if not null and trimm the str at the same time

check, if this works for you.

File -> Settings -> (type appe in search box) and select Appearance -> Select Intellij from dropdown option of Theme on the right (under UI Options).

Hope this helps someone.

If I don't want to define a minimal width because I don't know the amount of elements the only thing that worked to me was:

display: inline-block;
white-space: nowrap;

But only in Chrome and Safari :/

CMP subtracts the operands and sets the flags. Namely, it sets the zero flag if the difference is zero (operands are equal).

TEST sets the zero flag, ZF, when the result of the AND operation is zero. If two operands are equal, their bitwise AND is zero when both are zero. TEST also sets the sign flag, SF, when the most significant bit is set in the result, and the parity flag, PF, when the number of set bits is even.

JE [Jump if Equals] tests the zero flag and jumps if the flag is set. JE is an alias of JZ [Jump if Zero] so the disassembler cannot select one based on the opcode. JE is named such because the zero flag is set if the arguments to CMP are equal.

So,

TEST %eax, %eax
JE   400e77 <phase_1+0x23>

jumps if the %eax is zero.

Regarding the question,

” can someone explain why the compare() function exists if a comparison can be made using simple operands?

Relative to < and ==, the compare function is conceptually simpler and in practice it can be more efficient since it avoids two comparisons per item for ordinary ordering of items.

As an example of simplicity, for small integer values you can write a compare function like this:

auto compare( int a, int b ) -> int { return a - b; }

which is highly efficient.

Now for a structure

struct Foo
{
    int a;
    int b;
    int c;
};

auto compare( Foo const& x, Foo const& y )
    -> int
{
    if( int const r = compare( x.a, y.a ) ) { return r; }
    if( int const r = compare( x.b, y.b ) ) { return r; }
    return compare( x.c, y.c );
}

Trying to express this lexicographic compare directly in terms of < you wind up with horrendous complexity and inefficiency, relatively speaking.

With C++11, for the simplicity alone ordinary less-than comparison based lexicographic compare can be very simply implemented in terms of tuple comparison.

If you're using Anaconda to manage Python on your system, you can install it with:

$ conda install pyqt=4

Omit the =4 to install the most current version.

Answer from How to install PyQt4 in anaconda?

All the tricks are almost the same, but I like this one:

find <mydir> -type f -exec sed -i 's/<string1>/<string2>/g' {} +

• find <mydir>: look up in the directory.

• -type f:

  File is of type: regular file

• -exec command {} +:

  This variant of the -exec action runs the specified command on the selected files, but the command line is built by appending each selected file name at the end; the total number of invocations of the command will be much less than the number of matched files. The command line is built in much the same way that xargs builds its command lines. Only one instance of `{}' is allowed within the command. The command is executed in the starting directory.

The best way is to change any setting you want in your code.

Check out the below example:

using(WCFServiceClient client = new WCFServiceClient ())
{ 
    client.Endpoint.Binding.SendTimeout = new TimeSpan(0, 1, 30);
}

you may also place the followinng

<a href='javascript:alert("hello world!");'>Click me</a>

to your html-code, and when you click on 'Click me' hyperlink, javascript will appear in url-bar and Alert dialog will show

I think it is the best answer:

public static double StringToDouble(string toDouble)
{
    toDouble = toDouble.Replace(",", "."); //Replace every comma with dot

    //Count dots in toDouble, and if there is more than one dot, throw an exception.
    //Value such as "123.123.123" can't be converted to double
    int dotCount = 0;
    foreach (char c in toDouble) if (c == '.') dotCount++; //Increments dotCount for each dot in toDouble
    if (dotCount > 1) throw new Exception(); //If in toDouble is more than one dot, it means that toCount is not a double

    string left = toDouble.Split('.')[0]; //Everything before the dot
    string right = toDouble.Split('.')[1]; //Everything after the dot

    int iLeft = int.Parse(left); //Convert strings to ints
    int iRight = int.Parse(right);

    //We must use Math.Pow() instead of ^
    double d = iLeft + (iRight * Math.Pow(10, -(right.Length)));
    return d;
}

It seems that the setBackground() method doesn't work well on some platforms (I'm using Windows 7). I found this answer to this question helpful. However, I didn't entirely use it to solve my problem. Instead, I decided it'd be much easier and almost as aesthetic to color a panel next to the button.

req.params contains route parameters (in the path portion of the URL), and req.query contains the URL query parameters (after the ? in the URL).

You can also use req.param(name) to look up a parameter in both places (as well as req.body), but this method is now deprecated.

apt-get install python-setuptools python-pip

or

apt-get install python3-setuptools python3-pip

you'd also want to install the python packages...

Redirect the output to a file like this:

./a.sh > somefile 2>&1 &

This will redirect both stdout and stderr to the same file. If you want to redirect stdout and stderr to two different files use this:

./a.sh > stdoutfile 2> stderrfile &

You can use /dev/null as one or both of the files if you don't care about the stdout and/or stderr.

See bash manpage for details about redirections.

I am using this approach for a multi table and range sheet as a unique way.

Sub RemoveFilters(Ws As Worksheet)

        LO.ShowAutoFilter = True
        LO.AutoFilter.ShowAllData
    Next
    Ws.ShowAllData

You can reboot the device by sending the following broadcast:

$ adb shell am broadcast -a android.intent.action.BOOT_COMPLETED

Inside CONCATENATE you can use TRANSPOSE if you expand it (F9) then remove the surrounding {}brackets like this recommends

=CONCATENATE(TRANSPOSE(B2:B19))

Becomes

=CONCATENATE("Oh ","combining ", "a " ...)

You may need to add your own separator on the end, say create a column C and transpose that column.

=B1&" "
=B2&" "
=B3&" "

Eric Lippert wrote a detailed blog post about this subject a while back (additionally comparing it to VBScript). More accurately, he wrote about JScript, which is Microsoft's own implementation of ECMAScript, although very similar to JavaScript. I would imagine that you can assume the vast majority of behaviour would be the same for the JavaScript engine of Internet Explorer. Of course, the implementation will vary from browser to browser, though I suspect you could take a number of the common principles and apply them to other browsers.

Quoted from that page:

JScript uses a nongenerational mark-and-sweep garbage collector. It works like this:

• Every variable which is "in scope" is called a "scavenger". A scavenger may refer to a number, an object, a string, whatever. We maintain a list of scavengers -- variables are moved on to the scav list when they come into scope and off the scav list when they go out of scope.

• Every now and then the garbage collector runs. First it puts a "mark" on every object, variable, string, etc – all the memory tracked by the GC. (JScript uses the VARIANT data structure internally and there are plenty of extra unused bits in that structure, so we just set one of them.)

• Second, it clears the mark on the scavengers and the transitive closure of scavenger references. So if a scavenger object references a nonscavenger object then we clear the bits on the nonscavenger, and on everything that it refers to. (I am using the word "closure" in a different sense than in my earlier post.)

• At this point we know that all the memory still marked is allocated memory which cannot be reached by any path from any in-scope variable. All of those objects are instructed to tear themselves down, which destroys any circular references.

The main purpose of garbage collection is to allow the programmer not to worry about memory management of the objects they create and use, though of course there's no avoiding it sometimes - it is always beneficial to have at least a rough idea of how garbage collection works.

Historical note: an earlier revision of the answer had an incorrect reference to the delete operator. In JavaScript the delete operator removes a property from an object, and is wholly different to delete in C/C++.

With bootstrap 3 the best way to go about achieving what you want is ...with offsetting columns. Please see these examples for more detail:
http://getbootstrap.com/css/#grid-offsetting

In short, and without seeing your divs here's an example what might help, without using any custom classes. Just note how the "col-6" is used and how half of that is 3 ...so the "offset-3" is used. Splitting equally will allow the centered spacing you're going for:

<div class="container">
<div class="col-sm-6 col-sm-offset-3">
your centered, floating column
</div></div>

Don't know much VB.NET syntax but here's and idea

    graphics.DrawImage(source, new Size(48, 48)) 
End Using

You're not going to be able to modify the caller's shell because it's in a different process context. When child processes inherit your shell's variables, they're inheriting copies themselves.

One thing you can do is to write a script that emits the correct commands for tcsh or sh based how it's invoked. If you're script is "setit" then do:

ln -s setit setit-sh

and

ln -s setit setit-csh

Now either directly or in an alias, you do this from sh

eval `setit-sh`

or this from csh

eval `setit-csh`

setit uses $0 to determine its output style.

This is reminescent of how people use to get the TERM environment variable set.

The advantage here is that setit is just written in whichever shell you like as in:

#!/bin/bash
arg0=$0
arg0=${arg0##*/}
for nv in \
   NAME1=VALUE1 \
   NAME2=VALUE2
do
   if [ x$arg0 = xsetit-sh ]; then
      echo 'export '$nv' ;'
   elif [ x$arg0 = xsetit-csh ]; then
      echo 'setenv '${nv%%=*}' '${nv##*=}' ;'
   fi
done

with the symbolic links given above, and the eval of the backquoted expression, this has the desired result.

To simplify invocation for csh, tcsh, or similar shells:

alias dosetit 'eval `setit-csh`'

or for sh, bash, and the like:

alias dosetit='eval `setit-sh`'

One nice thing about this is that you only have to maintain the list in one place. In theory you could even stick the list in a file and put cat nvpairfilename between "in" and "do".

This is pretty much how login shell terminal settings used to be done: a script would output statments to be executed in the login shell. An alias would generally be used to make invocation simple, as in "tset vt100". As mentioned in another answer, there is also similar functionality in the INN UseNet news server.

I was in your shoes for a while and finally ended up using node.js, because it can do hybrid solutions like having web and socket server in one. So php backend can submit requests thru http to node web server and then broadcast it with websocket. Very efficiant way to go.

<?php $data = array('a'=>'apple','b'=>'banana','c'=>'orange');?>
<pre><?php print_r($data); ?></pre>

Result:
Array
(
          [a] => apple
          [b] => banana
          [c] => orange
)

As mentioned in the comments to the question, the JDBC-ODBC Bridge is - as the name indicates - only a mechanism for the JDBC layer to "talk to" the ODBC layer. Even if you had a JDBC-ODBC Bridge on your Mac you would also need to have

• an implementation of ODBC itself, and
• an appropriate ODBC driver for the target database (ACE/Jet, a.k.a. "Access")

So, for most people, using JDBC-ODBC Bridge technology to manipulate ACE/Jet ("Access") databases is really a practical option only under Windows. It is also important to note that the JDBC-ODBC Bridge will be has been removed in Java 8 (ref: here).

There are other ways of manipulating ACE/Jet databases from Java, such as UCanAccess and Jackcess. Both of these are pure Java implementations so they work on non-Windows platforms. For details on how to use UCanAccess see

Manipulating an Access database from Java without ODBC

In our case, everything LOOKED ok, but it took most of the day to figure this out:

TLDR: Check your certificate paths to make sure the root certificate is correct. In the case of COMODO certificates, it should say "USERTrust" and be issued by "AddTrust External CA Root". NOT "COMODO" issued by "COMODO RSA Certification Authority".

From the CloudFront docs: http://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/SecureConnections.html

If the origin server returns an invalid certificate or a self-signed certificate, or if the origin server returns the certificate chain in the wrong order, CloudFront drops the TCP connection, returns HTTP error code 502, and sets the X-Cache header to Error from cloudfront.

We had the right ciphers enabled as per: http://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/RequestAndResponseBehaviorCustomOrigin.html#RequestCustomEncryption

Our certificate was valid according to Google, Firefox and ssl-checker: https://www.sslshopper.com/ssl-checker.html

However the last certificate in the ssl checker chain was "COMODO RSA Domain Validation Secure Server CA", issued by "COMODO RSA Certification Authority"

It seems that CloudFront does not hold the certificate for "COMODO RSA Certification Authority" and as such thinks the certificate provided by the origin server is self signed.

This was working for a long time before apparently suddenly stopping. What happened was I had just updated our certificates for the year, but during the import, something was changed in the certificate path for all the previous certificates. They all started referencing "COMODO RSA Certification Authority" whereas before the chain was longer and the root was "AddTrust External CA Root".

Because of this, switching back to the older cert did not fix the cloudfront issue.

I had to delete the extra certificate named "COMODO RSA Certification Authority", the one that did not reference AddTrust. After doing this, all my website certificates' paths updated to point back to AddTrust/USERTrust again. Note can also open up the bad root certificate from the path, click "Details" -> "Edit Properties" and then disable it that way. This updated the path immediately. You may also need to delete multiple copies of the certificate, found under "Personal" and "Trusted Root Certificate Authorities"

Finally I had to re select the certificate in IIS to get it to serve the new certificate chain.

After all this, ssl-checker started displaying a third certificate in the chain, which pointed back to "AddTrust External CA Root"

Finally, CloudFront accepted the origin server's certificate and the provided chain as being trusted. Our CDN started working correctly again!

To prevent this happening in the future, we will need to export our newly generated certificates from a machine with the correct certificate chain, i.e. distrust or delete the certificate "COMODO RSA Certification Authroity" issued by "COMODO RSA Certification Authroity" (expiring in 2038). This only seems to affect windows machines, where this certificate is installed by default.

Once you have cloned the repo, you have everything: you can then hg up branchname or hg up tagname to update your working copy.

UP: hg up is a shortcut of hg update, which also has hg checkout alias for people with git habits.

The percent symbol means: any host, including remote and local connections.

The localhost allows only local connections.

(so to start off, if you don't need remote connections to your database, you can get rid of the appuser@'%' user right away)

So, yes, they are overlapping, but...

...there is a reason for setting both types of accounts, this is explained in the mysql docs: http://dev.mysql.com/doc/refman/5.7/en/adding-users.html.

If you have an have an anonymous user on your localhost, which you can spot with:

select Host from mysql.user where User='' and Host='localhost';

and if you just create the user appuser@'%' (and you not the appuser@'localhost'), then when the appuser mysql user connects from the local host, the anonymous user account is used (it has precedence over your appuser@'%' user).

And the fix for this is (as one can guess) to create the appuser@'localhost' (which is more specific that the local host anonymous user and will be used if your appuser connects from the localhost).

Use the DateTime.SpecifyKind static method.

Creates a new DateTime object that has the same number of ticks as the specified DateTime, but is designated as either local time, Coordinated Universal Time (UTC), or neither, as indicated by the specified DateTimeKind value.

Example:

DateTime dateTime = DateTime.Now;
DateTime other = DateTime.SpecifyKind(dateTime, DateTimeKind.Utc);

Console.WriteLine(dateTime + " " + dateTime.Kind); // 6/1/2011 4:14:54 PM Local
Console.WriteLine(other + " " + other.Kind);       // 6/1/2011 4:14:54 PM Utc

The best way use Java 8 time API:

  LocalDateTime ldt = timeStamp.toLocalDateTime();
  Timestamp ts = Timestamp.valueOf(ldt);

For use with JPA put in with your model (https://weblogs.java.net/blog/montanajava/archive/2014/06/17/using-java-8-datetime-classes-jpa):

@Converter(autoApply = true)
public class LocalDateTimeConverter implements AttributeConverter<LocalDateTime, Timestamp> {
    @Override
    public Timestamp convertToDatabaseColumn(LocalDateTime ldt) {
        return Timestamp.valueOf(ldt);
    }

    @Override
    public LocalDateTime convertToEntityAttribute(Timestamp ts) {
        return ts.toLocalDateTime();
    }
}

So now it is relative timezone independent time. Additionally it is easy do:

  LocalDate ld = ldt.toLocalDate();
  LocalTime lt = ldt.toLocalTime();

Formatting:

 DateTimeFormatter DATE_TME_FORMATTER = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm")
 String str = ldt.format(DATE_TME_FORMATTER);
 ldt = LocalDateTime.parse(str, DATE_TME_FORMATTER);

UPDATE: postgres 9.4.1208, HSQLDB 2.4.0 etc understand Java 8 Time API without any conversations!

For me, all I needed was setlocale(LC_ALL, "en_US.UTF-8");

Then, I could use even raw wchar_t characters.

This may be more work than you're looking to deal with in the short term, but I suspect in the long term it would be very beneficial for you to look into using Ant (or Maven, or even Bazel) instead of building jar's manually. That way you can just click on the ant file (if you use Eclipse) and rebuild the jar.

Alternatively, you may want to actually not have these config files in the jar at all - if you're expecting to need to replace these files regularly, or if it's supposed to be distributed to multiple parties, the config file should not be part of the jar at all.

if you remove the float: left from the a and add white-space: nowrap to the outer div

#myWorkContent{
    width:530px;
    height:210px;
    border: 13px solid #bed5cd;
    overflow-x: scroll;
    overflow-y: hidden;
    white-space: nowrap;
}
#myWorkContent a {
    display: inline;
}

this should work for any size or amount of images..

or even:

#myWorkContent a {
    display: inline-block;
    vertical-align: middle;
}

which would also vertically align images of different heights if required

test code

Going off of tbradley22's answer, but using .map instead:

var a = ["car", "bike", "scooter"];
a.map(function(entry) {
    var singleObj = {};
    singleObj['type'] = 'vehicle';
    singleObj['value'] = entry;
    return singleObj;
});

I'll tackle your second question first. Yes, the indentation can be reset by using a browser reset like Eric Meyers. Or a simple ul { margin: 0; padding: 0;} as indentation is, by default, enforced on the ul element.

As to the why, I suspect its to do with the current level of nesting, as unordered lists allow for nesting or maybe to do with the bullets positioning.

Edit: As Guffa mentioned, the list indentation is to ensure that the markers do not fall off the left edge.

(Update: August 2011)

As geofflane mentions in his answer, Java 7 now support named groups.
tchrist points out in the comment that the support is limited.
He details the limitations in his great answer "Java Regex Helper"

Java 7 regex named group support was presented back in September 2010 in Oracle's blog.

In the official release of Java 7, the constructs to support the named capturing group are:

• (?<name>capturing text) to define a named group "name"
• \k<name> to backreference a named group "name"
• ${name} to reference to captured group in Matcher's replacement string
• Matcher.group(String name) to return the captured input subsequence by the given "named group".

Other alternatives for pre-Java 7 were:

• Google named-regex (see John Hardy's answer)
  Gábor Lipták mentions (November 2012) that this project might not be active (with several outstanding bugs), and its GitHub fork could be considered instead.
• jregex (See Brian Clozel's answer)

(Original answer: Jan 2009, with the next two links now broken)

You can not refer to named group, unless you code your own version of Regex...

That is precisely what Gorbush2 did in this thread.

Regex2

(limited implementation, as pointed out again by tchrist, as it looks only for ASCII identifiers. tchrist details the limitation as:

only being able to have one named group per same name (which you don’t always have control over!) and not being able to use them for in-regex recursion.

Note: You can find true regex recursion examples in Perl and PCRE regexes, as mentioned in Regexp Power, PCRE specs and Matching Strings with Balanced Parentheses slide)

Example:

String:

"TEST 123"

RegExp:

"(?<login>\\w+) (?<id>\\d+)"

Access

matcher.group(1) ==> TEST
matcher.group("login") ==> TEST
matcher.name(1) ==> login

Replace

matcher.replaceAll("aaaaa_$1_sssss_$2____") ==> aaaaa_TEST_sssss_123____
matcher.replaceAll("aaaaa_${login}_sssss_${id}____") ==> aaaaa_TEST_sssss_123____

                    int[] newtemp = new int[2*(len) + 2];
                    //System.arraycopy(temp, start, newtemp, 0, len);
                    StringBuilder name = new StringBuilder();
                    for(int i = start; i< cursor; i++){
                        name.append((char)temp[i-1]);
                    }
                    // create Named group
                    head = createGroup(false);
                    ((GroupTail)root).name = name.toString();

                    capturingGroup = true;
                    tail = root;
                    head.next = expr(tail);
                    break;
                }

This is just a guess, but since port 80 is the conventional port for HTTP, you may have a webserver running on your system. Is IIS active?

If you are running IIS you may have the web farm service running. That was what was killing my xampp.

I tried several solutions from this page, but none worked. I had a series of numbered files which I simply wanted be ordered by alphabetical foldername so when piped to concat() they'd be in the same order. That is, preserve the order of the globbing input. Easy, right?

Here's my specific proof-of-concept code (print is just to see the order printed to the cli):

var order = require('gulp-order');
var gulp = require('gulp');
var print = require('gulp-print').default;

var options = {};

options.rootPath = {
  inputDir: process.env.INIT_CWD + '/Draft',
  inputGlob: '/**/*.md',
};

gulp.task('default', function(){
  gulp.src(options.rootPath.inputDir + options.rootPath.inputGlob, {base: '.'})
    .pipe(order([options.rootPath.inputDir + options.rootPath.inputGlob]))
    .pipe(print());
});

The reason for the madness of gulp.src? I determined that gulp.src was running async when I was able to use a sleep() function (using a .map with sleeptime incremented by index) to order the stream output properly.

The upshot of the async of src mean dirs with more files in it came after dirs with fewer files, because they took longer to process.

AlliterativeAlice's example helped me tremendously. In my case, though, the server I was talking to didn't like having single quotes around utf-8 in the content type. It failed with a generic "Server Error" and it took hours to figure out what it didn't like:

request.ContentType = "text/xml; encoding=utf-8";

A Function will not work, nor is it necessary:

Sub OpenWorkbook()
    Dim r1 As Range, r2 As Range, o As Workbook
    Set r1 = ThisWorkbook.Sheets("Sheet1").Range("A1")
    Set o = Workbooks.Open(Filename:="C:\TestFolder\ABC.xlsx")
    Set r2 = ActiveWorkbook.Sheets("Sheet1").Range("B2")
    [r1] = [r2]
    o.Close
End Sub

Try:

select v.*, row_number() over (partition by id order by elem) rn from
(select
    id,
    unnest(string_to_array(elements, ',')) AS elem
 from myTable) v

You mean staticly define a value, like this:

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

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

If you declare this in a mytest.c file:

static int my_variable;

Then this variable can only be seen from this file. The variable cannot be exported anywhere else.

If you declare inside a function the value of the variable will keep its value each time the function is called.

A static function cannot be exported from outside the file. So in a *.c file, you are hiding the functions and the variables if you declare them static.

Go through following code to convert the DateTime from 12 hrs to 24 hours.

string currentDateString = DateTime.Now.ToString("dd-MMM-yyyy h:mm tt");
DateTime currentDate = Convert.ToDateTime(currentDateString);
Console.WriteLine("String Current Date: " + currentDateString);
Console.WriteLine("Converted Date: " + currentDate.ToString("dd-MMM-yyyy HH:mm"));

Whenever you want the time should be displayed in24 hours use format "HH"

You can refer following link for further details: Custom Date and Time Format Strings

function routeToRoom(userId, passw, cb) {
    var roomId = 0;
    var nStore = require('nstore/lib/nstore').extend(require('nstore/lib/nstore/query')());
    var users = nStore.new('data/users.db', function() {
        users.find({
            user: userId,
            pass: passw
        }, function(err, results) {
            if (err) {
                roomId = -1;
            } else {
                roomId = results.creationix.room;
            }
            cb(roomId);
        });
    });
}
routeToRoom("alex", "123", function(id) {
    console.log(id);    
});

You need to use callbacks. That's how asynchronous IO works. Btw sys.puts is deprecated

When you go to a website, your browser sends a request to the web server including a lot of information. This information might look something like this:

GET /questions/18070154/get-operating-system-info-with-php HTTP/1.1  
Host: stackoverflow.com  
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_4) AppleWebKit/537.36 
            (KHTML, like Gecko) Chrome/28.0.1500.95 Safari/537.36 
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8  
Accept-Language: en-us,en;q=0.5  
Accept-Encoding: gzip,deflate,sdch  
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7  
Keep-Alive: 300  
Connection: keep-alive  
Cookie: <cookie data removed> 
Pragma: no-cache  
Cache-Control: no-cache

These information are all used by the web server to determine how to handle the request; the preferred language and whether compression is allowed.

In PHP, all this information is stored in the $_SERVER array. To see what you're sending to a web server, create a new PHP file and print out everything from the array.

<pre><?php print_r($_SERVER); ?></pre>

This will give you a nice representation of everything that's being sent to the server, from where you can extract the desired information, e.g. $_SERVER['HTTP_USER_AGENT'] to get the operating system and browser.

Change the File Permission using chmod command

Killing child process in shell script:

Many time we need to kill child process which are hanged or block for some reason. eg. FTP connection issue.

There are two approaches,

1) To create separate new parent for each child which will monitor and kill child process once timeout reached.

Create test.sh as follows,

#!/bin/bash

declare -a CMDs=("AAA" "BBB" "CCC" "DDD")
for CMD in ${CMDs[*]}; do
    (sleep 10 & PID=$!; echo "Started $CMD => $PID"; sleep 5; echo "Killing $CMD => $PID"; kill $PID; echo "$CMD Completed.") &
done
exit;

and watch processes which are having name as 'test' in other terminal using following command.

watch -n1 'ps x -o "%p %r %c" | grep "test" '

Above script will create 4 new child processes and their parents. Each child process will run for 10sec. But once timeout of 5sec reach, thier respective parent processes will kill those childs. So child won't be able to complete execution(10sec). Play around those timings(switch 10 and 5) to see another behaviour. In that case child will finish execution in 5sec before it reaches timeout of 10sec.

2) Let the current parent monitor and kill child process once timeout reached. This won't create separate parent to monitor each child. Also you can manage all child processes properly within same parent.

Create test.sh as follows,

#!/bin/bash

declare -A CPIDs;
declare -a CMDs=("AAA" "BBB" "CCC" "DDD")

CMD_TIME=15;
for CMD in ${CMDs[*]}; do
    (echo "Started..$CMD"; sleep $CMD_TIME; echo "$CMD Done";) &
    CPIDs[$!]="$RN";
    sleep 1;
done

GPID=$(ps -o pgid= $$);
CNT_TIME_OUT=10;
CNT=0;
while (true); do
    declare -A TMP_CPIDs;

    for PID in "${!CPIDs[@]}"; do
        echo "Checking "${CPIDs[$PID]}"=>"$PID;

        if ps -p $PID > /dev/null ; then
          echo "-->"${CPIDs[$PID]}"=>"$PID" is running..";
          TMP_CPIDs[$PID]=${CPIDs[$PID]};
        else
          echo "-->"${CPIDs[$PID]}"=>"$PID" is completed.";
        fi
    done

    if [ ${#TMP_CPIDs[@]} == 0 ]; then
        echo "All commands completed.";
        break;
    else
        unset CPIDs;
        declare -A CPIDs;
        for PID in "${!TMP_CPIDs[@]}"; do
            CPIDs[$PID]=${TMP_CPIDs[$PID]};
        done
        unset TMP_CPIDs;

        if [ $CNT -gt $CNT_TIME_OUT ]; then
            echo ${CPIDs[@]}"PIDs not reponding. Timeout reached $CNT sec. killing all childern with GPID $GPID..";
            kill -- -$GPID;
        fi
    fi

    CNT=$((CNT+1));
    echo "waiting since $b secs..";
    sleep 1;
done

exit;

and watch processes which are having name as 'test' in other terminal using following command.

watch -n1 'ps x -o "%p %r %c" | grep "test" '

Above script will create 4 new child processes. We are storing pids of all child process and looping over them to check if they are finished their execution or still running. Child process will execution till CMD_TIME time. But if CNT_TIME_OUT timeout reach , All children will get killed by parent process. You can switch timing and play around with script to see behavior. One drawback of this approach is , it is using group id for killing all child tree. But parent process itself belong to same group so it will also get killed.

You may need to assign other group id to parent process if you don’t want parent to be killed.

I wrote this extension method based off @Lee's response to the OP. Note, a default parameter was used (requiring C# 4.0). However, an overloaded method call in C# 3.0 would suffice.

/// <summary>
/// Method that returns all the duplicates (distinct) in the collection.
/// </summary>
/// <typeparam name="T">The type of the collection.</typeparam>
/// <param name="source">The source collection to detect for duplicates</param>
/// <param name="distinct">Specify <b>true</b> to only return distinct elements.</param>
/// <returns>A distinct list of duplicates found in the source collection.</returns>
/// <remarks>This is an extension method to IEnumerable&lt;T&gt;</remarks>
public static IEnumerable<T> Duplicates<T>
         (this IEnumerable<T> source, bool distinct = true)
{
     if (source == null)
     {
        throw new ArgumentNullException("source");
     }

     // select the elements that are repeated
     IEnumerable<T> result = source.GroupBy(a => a).SelectMany(a => a.Skip(1));

     // distinct?
     if (distinct == true)
     {
        // deferred execution helps us here
        result = result.Distinct();
     }

     return result;
}

grep matches, grep -v does the inverse. If you need to "match A but not B" you usually use pipes:

grep "${PATT}" file | grep -v "${NOTPATT}"

If you use Java and spring MVC you just need to add the following annotation to your method returning your page :

@CrossOrigin(origins = "*")

"*" is to allow your page to be accessible from anywhere. See https://developer.mozilla.org/fr/docs/Web/HTTP/Headers/Access-Control-Allow-Origin for more details about that.

Every number from 1,2,5,6,9,10... is divisible by 4 with remainder 1 or 2.

>>> ','.join(str(i) for i in xrange(100) if i % 4 in (1,2))
'1,2,5,6,9,10,13,14,...'

This worked for me, just put it into any layout you want to.

<FrameLayout
    android:layout_width="32dp"
    android:layout_height="192dp">

    <SeekBar
        android:layout_width="192dp"
        android:layout_height="32dp"
        android:layout_gravity="center"
        android:rotation="270" />

</FrameLayout>

Yes. First, hook into the column added event:

this.dataGridView1.ColumnAdded += new DataGridViewColumnEventHandler(dataGridView1_ColumnAdded);

Then, in your event handler, just append the text you want to:

private void dataGridView1_ColumnAdded(object sender, DataGridViewColumnEventArgs e)
{
    e.Column.HeaderText += additionalHeaderText;
}

You can simply do

node --version

or short form would also do

node -v

If above commands does not work, you have done something wrong in installation, reinstall the node.js and try.

Just use the HtmlHelper ActionLink and set the RouteValues and HtmlAttributes accordingly.

@Html.ActionLink(Reports.RunReport, "RunReport", new { controller = "Performance", reportView = Model.ReportView.ToString() }, new { target = "_blank" })

You should be able to use join, which joins on the index as default. Given your desired result, you must use outer as the join type.

>>> df1.join(df2, how='outer')
            V1  V2
A 1/1/2012  12  15
  2/1/2012  14 NaN
  3/1/2012 NaN  21
B 1/1/2012  15  24
  2/1/2012   8   9
C 1/1/2012  17 NaN
  2/1/2012   9 NaN
D 1/1/2012 NaN   7
  2/1/2012 NaN  16

Signature: _.join(other, on=None, how='left', lsuffix='', rsuffix='', sort=False) Docstring: Join columns with other DataFrame either on index or on a key column. Efficiently Join multiple DataFrame objects by index at once by passing a list.

Adding to @adardesign's answer, if you want to reset all files that have been added to assume-unchanged list to no-assume-unchanged in one go, you can do the following:

git ls-files -v | grep '^h' | sed 's/^..//' | sed 's/\ /\\ /g' | xargs -I FILE git update-index --no-assume-unchanged FILE || true

This will just strip out the two characters output from grep i.e. "h ", then escape any spaces that may be present in file names, and finally || true will prevent the command to terminate prematurely in case some files in the loop has errors.

For information this comes under Item 48 - Avoid float and double when exact values are required, of Effective Java 2nd edition by Joshua Bloch. This book is jam packed with good stuff and definitely worth a look.

I would first suggest that you step back and look at organizing your plays to not require such complexity, but if you really really do, use the following:

   vars:
    myvariable: "{{[param1|default(''), param2|default(''), param3|default('')]|join(',')}}"

CREATE TABLE [dbo].[History](
    [ID] [int] IDENTITY(1,1) NOT NULL,
    [RequestID] [int] NOT NULL,
    [EmployeeID] [varchar](50) NOT NULL,
    [DateStamp] [datetime] NOT NULL,
 CONSTRAINT [PK_History] PRIMARY KEY CLUSTERED 
(
    [ID] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON)
) ON [PRIMARY]

you can use following these component to float right

alignItems aligns children in the cross direction. For example, if children are flowing vertically, alignItems controls how they align horizontally.

alignItems: 'flex-end'

justifyContent aligns children in the main direction. For example, if children are flowing vertically, justifyContent controls how they align vertically.

justifyContent: 'flex-end'

alignSelf controls how a child aligns in the cross direction,

alignSelf : 'flex-end'

This worked for me:

1.Right click pom.xml
2.Run Maven > Goals
3.Edit maven goals

You can try my lib for multiple bluetooth connection :

In my case, I was looping through a series of objects from an XML file, but some of the instances apparently were not objects which was causing the error. Checking if the object was empty before processing it fixed the problem.

In other words, without checking if the object was empty, the script would error out on any empty object with the error as given below.

Trying to get property of non-object

For Example:

if (!empty($this->xml_data->thing1->thing2))
{
   foreach ($this->xml_data->thing1->thing2 as $thing)
   {

   }
}

In .net 4.0 Microsoft removed the ability to add DLLs to the Assembly simply by dragging and dropping.

Instead you need to use gacutil.exe, or create an installer to do it. Microsoft actually doesn’t recommend using gacutil, but I went that route anyway.

To use gacutil on a development machine go to:
Start -> programs -> Microsoft Visual studio 2010 -> Visual Studio Tools -> Visual Studio Command Prompt (2010)

Then use these commands to uninstall and Reinstall respectively. Note I did NOT include .dll in the uninstall command.
gacutil /u myDLL
gacutil /i "C:\Program Files\Custom\myDLL.dll"

To use Gacutil on a non-development machine you will have to copy the executable and config file from your dev machine to the production machine. It looks like there are a few different versions of Gacutil. The one that worked for me, I found here:
C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\NETFX 4.0 Tools\gacutil.exe C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\NETFX 4.0 Tools\gacutil.exe.config

Copy the files here or to the appropriate .net folder;
C:\Windows\Microsoft.NET\Framework\v4.0.30319

Then use these commands to uninstall and reinstall respectively
"C:\Users\BHJeremy\Desktop\Installing to the Gac in .net 4.0\gacutil.exe" /u "myDLL"

"C:\Windows\Microsoft.NET\Framework\v4.0.30319\gacutil.exe" /i "C:\Program Files\Custom\myDLL.dll"

The query should be:

(&(objectCategory=user)(memberOf=CN=Distribution Groups,OU=Mybusiness,DC=mydomain.local,DC=com))

You missed & and ()

Not forgetting

.equalsIgnoreCase(String)

if you're not worried about that sort of thing...

While dragging the TextBox it self Press F4 for Properties and under the Textmode set to Multiline, The representation of multiline to a text box is it can be sizable at 6 sides. And no need to include any newline characters for getting multiline. May be you set it multiline but you dint increased the size of the Textbox at design time.

public class User implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @Column(name = "USER_ID")
    Long userId;

    @OneToMany(fetch = FetchType.LAZY, mappedBy = "sender", cascade = CascadeType.ALL)
    List<Notification> sender;

    @OneToMany(fetch = FetchType.LAZY, mappedBy = "receiver", cascade = CascadeType.ALL)
    List<Notification> receiver;
}

public class Notification implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id

    @Column(name = "NOTIFICATION_ID")
    Long notificationId;

    @Column(name = "TEXT")
    String text;

    @Column(name = "ALERT_STATUS")
    @Enumerated(EnumType.STRING)
    AlertStatus alertStatus = AlertStatus.NEW;

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "SENDER_ID")
    @JsonIgnore
    User sender;

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "RECEIVER_ID")
    @JsonIgnore
    User receiver;
}

What I understood from the answer. mappedy="sender" value should be the same in the notification model. I will give you an example..

User model:

@OneToMany(fetch = FetchType.LAZY, mappedBy = "**sender**", cascade = CascadeType.ALL)
    List<Notification> sender;

    @OneToMany(fetch = FetchType.LAZY, mappedBy = "**receiver**", cascade = CascadeType.ALL)
    List<Notification> receiver;

Notification model:

@OneToMany(fetch = FetchType.LAZY, mappedBy = "sender", cascade = CascadeType.ALL)
    List<Notification> **sender**;

    @OneToMany(fetch = FetchType.LAZY, mappedBy = "receiver", cascade = CascadeType.ALL)
    List<Notification> **receiver**;

I gave bold font to user model and notification field. User model mappedBy="sender " should be equal to notification List sender; and mappedBy="receiver" should be equal to notification List receiver; If not, you will get error.

The other answers are generally correct and all outdated. Do use java.time, the modern Java date and time API, for your date and time work. With java.time your job has also become a lot easier compared to the situation when this question was asked in February 2014.

    String dateTimeString = "2014-01-16T10:25:00";
    LocalDateTime dateTime = LocalDateTime.parse(dateTimeString);
    LocalDateTime now = LocalDateTime.now(ZoneId.systemDefault());

    if (dateTime.isBefore(now)) {
        System.out.println(dateTimeString + " is in the past");
    } else if (dateTime.isAfter(now)) {
        System.out.println(dateTimeString + " is in the future");
    } else {
        System.out.println(dateTimeString + " is now");
    }

When running in 2020 output from this snippet is:

2014-01-16T10:25:00 is in the past

Since your string doesn’t inform of us any time zone or UTC offset, we need to know what was understood. The code above uses the device’ time zone setting. For a known time zone use like for example ZoneId.of("Asia/Ulaanbaatar"). For UTC specify ZoneOffset.UTC.

I am exploiting the fact that your string is in ISO 8601 format. The classes of java.time parse the most common ISO 8601 variants without us having to give any formatter.

Question: For Android development doesn’t java.time require Android API level 26?

java.time works nicely on both older and newer Android devices. It just requires at least Java 6.

• In Java 8 and later and on newer Android devices (from API level 26) the modern API comes built-in.
• In non-Android Java 6 and 7 get the ThreeTen Backport, the backport of the modern classes (ThreeTen for JSR 310; see the links at the bottom).
• On (older) Android use the Android edition of ThreeTen Backport. It’s called ThreeTenABP. And make sure you import the date and time classes from org.threeten.bp with subpackages.

This post pertains to R proxy issues on *nix. You should know that R has many libraries/methods to fetch data over internet.

For 'curl', 'libcurl', 'wget' etc, just do the following:

1. Open a terminal. Type the following command:

   sudo gedit /etc/R/Renviron.site
   

2. Enter the following lines:

   http_proxy='http://username:[email protected]:port/'
   https_proxy='https://username:[email protected]:port/'
   

   Replace username, password, abc.com, xyz.com and port with these settings specific to your network.

3. Quit R and launch again.

This should solve your problem with 'libcurl' and 'curl' method. However, I have not tried it with 'httr'. One way to do that with 'httr' only for that session is as follows:

library(httr)
set_config(use_proxy(url="abc.com",port=8080, username="username", password="password"))

You need to substitute settings specific to your n/w in relevant fields.

Memory allocated on the heap can be subject to high-water marks. This is complicated by Python's internal optimizations for allocating small objects (PyObject_Malloc) in 4 KiB pools, classed for allocation sizes at multiples of 8 bytes -- up to 256 bytes (512 bytes in 3.3). The pools themselves are in 256 KiB arenas, so if just one block in one pool is used, the entire 256 KiB arena will not be released. In Python 3.3 the small object allocator was switched to using anonymous memory maps instead of the heap, so it should perform better at releasing memory.

Additionally, the built-in types maintain freelists of previously allocated objects that may or may not use the small object allocator. The int type maintains a freelist with its own allocated memory, and clearing it requires calling PyInt_ClearFreeList(). This can be called indirectly by doing a full gc.collect.

Try it like this, and tell me what you get. Here's the link for psutil.Process.memory_info.

import os
import gc
import psutil

proc = psutil.Process(os.getpid())
gc.collect()
mem0 = proc.get_memory_info().rss

# create approx. 10**7 int objects and pointers
foo = ['abc' for x in range(10**7)]
mem1 = proc.get_memory_info().rss

# unreference, including x == 9999999
del foo, x
mem2 = proc.get_memory_info().rss

# collect() calls PyInt_ClearFreeList()
# or use ctypes: pythonapi.PyInt_ClearFreeList()
gc.collect()

Edit:

I switched to measuring relative to the process VM size to eliminate the effects of other processes in the system.

The C runtime (e.g. glibc, msvcrt) shrinks the heap when contiguous free space at the top reaches a constant, dynamic, or configurable threshold. With glibc you can tune this with mallopt (M_TRIM_THRESHOLD). Given this, it isn't surprising if the heap shrinks by more -- even a lot more -- than the block that you free.

In 3.x range doesn't create a list, so the test above won't create 10 million int objects. Even if it did, the int type in 3.x is basically a 2.x long, which doesn't implement a freelist.

JFrame.dispose() affects only to this frame (release all of the native screen resources used by this component, its subcomponents, and all children). System.exit() affects to entire JVM.

If you want to close all JFrame or all Window (since Frames extend Windows) to terminate the application in an ordered mode, you can do some like this:

Arrays.asList(Window.getWindows()).forEach(e -> e.dispose()); // or JFrame.getFrames()

Add rows:

And cells.

Here's an old discussion thread where I listed the main differences and the conditions in which you should use each of these methods. I think you may find it useful to go through the discussion.

To explain the differences as relevant to your posted example:

a. When you use RegisterStartupScript, it will render your script after all the elements in the page (right before the form's end tag). This enables the script to call or reference page elements without the possibility of it not finding them in the Page's DOM.

Here is the rendered source of the page when you invoke the RegisterStartupScript method:

<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1"><title></title></head>
<body>
    <form name="form1" method="post" action="StartupScript.aspx" id="form1">
        <div>
            <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="someViewstategibberish" />
        </div>
        <div> <span id="lblDisplayDate">Label</span>
            <br />
            <input type="submit" name="btnPostback" value="Register Startup Script" id="btnPostback" />
            <br />
            <input type="submit" name="btnPostBack2" value="Register" id="btnPostBack2" />
        </div>
        <div>
            <input type="hidden" name="__EVENTVALIDATION" id="__EVENTVALIDATION" value="someViewstategibberish" />
        </div>
        <!-- Note this part -->
        <script language='javascript'>
            var lbl = document.getElementById('lblDisplayDate');
            lbl.style.color = 'red';
        </script>
    </form>
    <!-- Note this part -->
</body>
</html>

b. When you use RegisterClientScriptBlock, the script is rendered right after the Viewstate tag, but before any of the page elements. Since this is a direct script (not a function that can be called, it will immediately be executed by the browser. But the browser does not find the label in the Page's DOM at this stage and hence you should receive an "Object not found" error.

Here is the rendered source of the page when you invoke the RegisterClientScriptBlock method:

<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1"><title></title></head>
<body>
    <form name="form1" method="post" action="StartupScript.aspx" id="form1">
        <div>
            <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="someViewstategibberish" />
        </div>
        <script language='javascript'>
            var lbl = document.getElementById('lblDisplayDate');
            // Error is thrown in the next line because lbl is null.
            lbl.style.color = 'green';

Therefore, to summarize, you should call the latter method if you intend to render a function definition. You can then render the call to that function using the former method (or add a client side attribute).

Edit after comments:

For instance, the following function would work:

protected void btnPostBack2_Click(object sender, EventArgs e) 
{ 
  System.Text.StringBuilder sb = new System.Text.StringBuilder(); 
  sb.Append("<script language='javascript'>function ChangeColor() {"); 
  sb.Append("var lbl = document.getElementById('lblDisplayDate');"); 
  sb.Append("lbl.style.color='green';"); 
  sb.Append("}</script>"); 

  //Render the function definition. 
  if (!ClientScript.IsClientScriptBlockRegistered("JSScriptBlock")) 
  {
    ClientScript.RegisterClientScriptBlock(this.GetType(), "JSScriptBlock", sb.ToString()); 
  }

  //Render the function invocation. 
  string funcCall = "<script language='javascript'>ChangeColor();</script>"; 

  if (!ClientScript.IsStartupScriptRegistered("JSScript"))
  { 
    ClientScript.RegisterStartupScript(this.GetType(), "JSScript", funcCall); 
  } 
} 

In the meantime, a time-window capability was added. See this link.

Why don't you just right click on the main() method and choose "Debug As... Java Application"?

Actually the "Remote" option in Configuration Menu for Plug-In works by me (Win7 64, ie8 with all updates), however:

1. You need administrator rights
2. The plug-in should be disabled before pressing the remove button
3. You need restart internet-explorer to see the changes.

Also the previous comment about browsing-history->view objects was also useful if plug-in was installed right now.

Regards!

I've found a working code:

JSONParser parser = new JSONParser();
Object obj  = parser.parse(content);
JSONArray array = new JSONArray();
array.add(obj);

The easiest way to add and remove ranges in a string is to use the StringBuilder.

var theString = "ABCDEFGHIJ";
var aStringBuilder = new StringBuilder(theString);
aStringBuilder.Remove(3, 2);
aStringBuilder.Insert(3, "ZX");
theString = aStringBuilder.ToString();

An alternative is to use String.Substring, but I think the StringBuilder code gets more readable.

I had exactly the same error. My network is an internal one of a company. The proxy has been disabled from the IT team so for that we do not have to enable any proxy settings. I have commented the proxy setting in settings.xml file from the below mentioned locations C:\Users\vijay.singh.m2\settings.xml This fixed the same issue for me

If you just want to get the minimum of a list, instead of sorting it and then getting the first element (O(N log N)), you can use do it in linear time using min:

<T extends Object & Comparable<? super T>> T min(Collection<? extends T> coll)

That looks gnarly at first, but looking at your previous questions, you have a List<String>. In short: min works on it.

For the long answer: all that super and extends stuff in the generic type constraints is what Josh Bloch calls the PECS principle (usually presented next to a picture of Arnold -- I'M NOT KIDDING!)

Producer Extends, Consumer Super

It essentially makes generics more powerful, since the constraints are more flexible while still preserving type safety (see: what is the difference between ‘super’ and ‘extends’ in Java Generics)

Already mentioned previously by swilliams, but with an example below (Javascript):

// Function wrapping inner for loop
function CriteriaMatch(record, criteria) {
  for (var k in criteria) {
    if (!(k in record))
      return false;

    if (record[k] != criteria[k])
      return false;
  }

  return true;
}

// Outer for loop implementing continue if inner for loop returns false
var result = [];

for (var i = 0; i < _table.length; i++) {
  var r = _table[i];

  if (!CriteriaMatch(r[i], criteria))
    continue;

  result.add(r);
}

You can omit the import statements and refer to them using the entire path. Eg:

java.util.Date javaDate = new java.util.Date()
my.own.Date myDate = new my.own.Date();

But I would say that using two classes with the same name and a similiar function is usually not the best idea unless you can make it really clear which is which.

I would like to show a little example on how is and == are involved in immutable types. Try that:

a = 19998989890
b = 19998989889 +1
>>> a is b
False
>>> a == b
True

is compares two objects in memory, == compares their values. For example, you can see that small integers are cached by Python:

c = 1
b = 1
>>> b is c
True

You should use == when comparing values and is when comparing identities. (Also, from an English point of view, "equals" is different from "is".)

it works for me !!

in mysql table

DATETIME

in entity:

private Date startDate;

in process:

objectEntity.setStartDate(new Date());

in preparedStatement:

pstm.setDate(9, new java.sql.Date(objEntity.getStartDate().getTime()));

If you want to customize the configuration then use the below methodology of creating OKhttpclient first and then add builder on top of it.

private final OkHttpClient client = new OkHttpClient();

// Copy to customize OkHttp for this request.
OkHttpClient client1 = client.newBuilder()
    .readTimeout(500, TimeUnit.MILLISECONDS)
    .build();
try (Response response = client1.newCall(request).execute()) {
    System.out.println("Response 1 succeeded: " + response);
} catch (IOException e) {
    System.out.println("Response 1 failed: " + e);
}

<?php

$string = 'foo';

if (preg_match('/[\'^£$%&*()}{@#~?><>,|=_+¬-]/', $string))
{
    // one or more of the 'special characters' found in $string
}

If you will use the new list later, you can simply set the elem to None, and then judge it in the later loop, like this

for i in li:
    i = None

for elem in li:
    if elem is None:
        continue

In this way, you dont't need copy the list and it's easier to understand.

The typical pattern is to check out the root project folder (=the one containing a file called ".project") from SVN using eclipse's svn integration (SVN repository exploring perspective). The project is then recognized automatically.

1. It is possible to get the command line shell output of a process as described here : http://www.c-sharpcorner.com/UploadFile/edwinlima/SystemDiagnosticProcess12052005035444AM/SystemDiagnosticProcess.aspx

2. This depends on mencoder. If it ouputs this status on the command line then yes :)

But why don't I have to install a certificate locally for the site?

Well the code that you are using is explicitly designed to accept the certificate without doing any checks whatsoever. This is not good practice ... but if that is what you want to do, then (obviously) there is no need to install a certificate that your code is explicitly ignoring.

Shouldn't I have to install a certificate locally and load it for this program or is it downloaded behind the covers?

No, and no. See above.

Is the traffic between the client to the remote site still encrypted in transmission?

Yes it is. However, the problem is that since you have told it to trust the server's certificate without doing any checks, you don't know if you are talking to the real server, or to some other site that is pretending to be the real server. Whether this is a problem depends on the circumstances.

If we used the browser as an example, typically a browser doesn't ask the user to explicitly install a certificate for each ssl site visited.

The browser has a set of trusted root certificates pre-installed. Most times, when you visit an "https" site, the browser can verify that the site's certificate is (ultimately, via the certificate chain) secured by one of those trusted certs. If the browser doesn't recognize the cert at the start of the chain as being a trusted cert (or if the certificates are out of date or otherwise invalid / inappropriate), then it will display a warning.

Java works the same way. The JVM's keystore has a set of trusted certificates, and the same process is used to check the certificate is secured by a trusted certificate.

Does the java https client api support some type of mechanism to download certificate information automatically?

No. Allowing applications to download certificates from random places, and install them (as trusted) in the system keystore would be a security hole.

Use the parentesis syntax of Razor:

@(Model.address + " " + Model.city)

or

@(String.Format("{0} {1}", Model.address, Model.city))

Update: With C# 6 you can also use the $-Notation (officially interpolated strings):

@($"{Model.address} {Model.city}")

You can convert your RDD to a DataFrame then show() it.

// For implicit conversion from RDD to DataFrame
import spark.implicits._

fruits = sc.parallelize([("apple", 1), ("banana", 2), ("orange", 17)])

// convert to DF then show it
fruits.toDF().show()

This will show the top 20 lines of your data, so the size of your data should not be an issue.

+------+---+                                                                    
|    _1| _2|
+------+---+
| apple|  1|
|banana|  2|
|orange| 17|

Your usage of now() is correct. However, you need to use one type of quotes around the entire query and another around the values.

You can modify your query to use double quotes at the beginning and end, and single quotes around $somename:

$update_query = "UPDATE db.tablename SET insert_time=now() WHERE username='$somename'";

Adding the following before the RETURN statement would solve for the cases where a leading space was included in the field:

SET @Value = LTRIM(RTRIM(@Value))

(For completeness)

You could also query the (SQL-standard) information schema:

SELECT
    table_schema || '.' || table_name
FROM
    information_schema.tables
WHERE
    table_type = 'BASE TABLE'
AND
    table_schema NOT IN ('pg_catalog', 'information_schema');

Sometimes it's knowing what to ask. I didn't know as I am a developer who has taken on some DevOps work.

Apparently 'passwordless' or NOPASSWD login is a thing which you need to put in the /etc/sudoers file.

The answer to my question is at Ansible: best practice for maintaining list of sudoers.

The Ansible playbook code fragment looks like this from my problem:

- name: Make sure we have a 'wheel' group
  group:
    name: wheel
    state: present

- name: Allow 'wheel' group to have passwordless sudo
  lineinfile:
    dest: /etc/sudoers
    state: present
    regexp: '^%wheel'
    line: '%wheel ALL=(ALL) NOPASSWD: ALL'
    validate: 'visudo -cf %s'

- name: Add sudoers users to wheel group
  user:
    name=deployer
    groups=wheel
    append=yes
    state=present
    createhome=yes

- name: Set up authorized keys for the deployer user
  authorized_key: user=deployer key="{{item}}"
  with_file:
    - /home/railsdev/.ssh/id_rsa.pub

And the best part is that the solution is idempotent. It doesn't add the line

%wheel ALL=(ALL) NOPASSWD: ALL

to /etc/sudoers when the playbook is run a subsequent time. And yes...I was able to ssh into the server as "deployer" and run sudo commands without having to give a password.

Do you have to use a HashMap? If you only need the Map Interface use a TreeMap

If you want to sort by comparing values in the HashMap. You have to write code to do this, if you want to do it once you can sort the values of your HashMap:

Map<String, Person> people = new HashMap<>();
Person jim = new Person("Jim", 25);
Person scott = new Person("Scott", 28);
Person anna = new Person("Anna", 23);

people.put(jim.getName(), jim);
people.put(scott.getName(), scott);
people.put(anna.getName(), anna);

// not yet sorted
List<Person> peopleByAge = new ArrayList<>(people.values());

Collections.sort(peopleByAge, Comparator.comparing(Person::getAge));

for (Person p : peopleByAge) {
    System.out.println(p.getName() + "\t" + p.getAge());
}

If you want to access this sorted list often, then you could insert your elements into a HashMap<TreeSet<Person>>, though the semantics of sets and lists are a bit different.

You've got a couple regexes now which will do what you want, so that's adequately covered.

What hasn't been mentioned is why your attempt won't work: Inside a character class, $ (as well as ^, ., and /) has no special meaning, so [/$] matches either a literal / or a literal $ rather than terminating the regex (/) or matching end-of-line ($).

It sets result to the (unsigned) value resulting from putting the 8 bits of value in the lowest 8 bits of result.

The reason something like this is necessary is that byte is a signed type in Java. If you just wrote:

int result = value;

then result would end up with the value ff ff ff fe instead of 00 00 00 fe. A further subtlety is that the & is defined to operate only on int values¹, so what happens is:

1. value is promoted to an int (ff ff ff fe).
2. 0xff is an int literal (00 00 00 ff).
3. The & is applied to yield the desired value for result.

(The point is that conversion to int happens before the & operator is applied.)

1_{Well, not quite. The & operator works on long values as well, if either operand is a long. But not on byte. See the Java Language Specification, sections 15.22.1 and 5.6.2.}

You could try the same address with HTTP instead of HTTPS. Be aware that this does use HTTP instead of HTTPS and only some sites might support this method.

Example address: https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-10.3.0-amd64-netinst.iso

wget http://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-10.3.0-amd64-netinst.iso

*notice the http:// instead of https://.

This is probably not recommended though :)

If you can, try use curl.

EDIT:

FYI an example with username (and prompt for password) would be:

curl --user $USERNAME -O http://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-10.3.0-amd64-netinst.iso

Where -O is

 -O, --remote-name
              Write output to a local file named like the remote file we get. (Only the file part of the remote file is used, the path is cut off.)

In your test, you are comparing the two TestParent beans, not the single TestedChild bean.

Also, Spring proxies your @Configuration class so that when you call one of the @Bean annotated methods, it caches the result and always returns the same object on future calls.

See here:

• How does Spring @Configuration cache references to beans

Directly from the docs:

$comma_separated = implode(",", $array);

First of all, you need to check that the IIS is installed in your machine, for that you can go to:

Control Panel --> Add or Remove Programs --> Windows Features --> And Check if Internet Information Services is installed with at least the 'Web Administration Tools' Enabled and The 'World Wide Web Service'

If not, check it, and Press Accept to install it.

Once that is done, you need to go to Administrative Tools in Control Panel and the IIS Will be there. Or simply run inetmgr (after Win+R).

Edit: You should have something like this:

You can't have cells of arbitrarily different widths, this is generally a standard behaviour of tables from any space, e.g. Excel, otherwise it's no longer a table but just a list of text.

You can however have cells span multiple columns, such as:

<table>
    <tr>
        <td>25</td>
        <td>50</td>
        <td>25</td>
    </tr>
    <tr>
        <td colspan="2">75</td>
        <td>20</td>
    </tr>
</table>

As an aside, you should avoid using style attributes like border and bgcolor and prefer CSS for those.

Do a describe on dba_arguments, dba_errors, dba_procedures, dba_objects, dba_source, dba_object_size. Each of these has part of the pictures for looking at the procedures and functions.

Also the object_type in dba_objects for packages is 'PACKAGE' for the definition and 'PACKAGE BODY" for the body.

If you are comparing schemas on the same database then try:

select * from dba_objects 
   where schema_name = 'ASCHEMA' 
     and object_type in ( 'PROCEDURE', 'PACKAGE', 'FUNCTION', 'PACKAGE BODY' )
minus
select * from dba_objects 
where schema_name = 'BSCHEMA' 
  and object_type in ( 'PROCEDURE', 'PACKAGE', 'FUNCTION', 'PACKAGE BODY' )

and switch around the orders of ASCHEMA and BSCHEMA.

If you also need to look at triggers and comparing other stuff between the schemas you should take a look at the Article on Ask Tom about comparing schemas

Strangely, for me it's SubmitChanges as opposed to SaveChanges:

    foreach (var item in w)
    {
        if (Convert.ToInt32(e.CommandArgument) == item.ID)
        {
            item.Sort = 1;
        }
        else
        {
            item.Sort = null;
        }
        db.SubmitChanges();            
    }                   

Both System.Timers.Timer and System.Threading.Timer will work for services.

The timers you want to avoid are System.Web.UI.Timer and System.Windows.Forms.Timer, which are respectively for ASP applications and WinForms. Using those will cause the service to load an additional assembly which is not really needed for the type of application you are building.

Use System.Timers.Timer like the following example (also, make sure that you use a class level variable to prevent garbage collection, as stated in Tim Robinson's answer):

using System;
using System.Timers;

public class Timer1
{
    private static System.Timers.Timer aTimer;

    public static void Main()
    {
        // Normally, the timer is declared at the class level,
        // so that it stays in scope as long as it is needed.
        // If the timer is declared in a long-running method,  
        // KeepAlive must be used to prevent the JIT compiler 
        // from allowing aggressive garbage collection to occur 
        // before the method ends. (See end of method.)
        //System.Timers.Timer aTimer;

        // Create a timer with a ten second interval.
        aTimer = new System.Timers.Timer(10000);

        // Hook up the Elapsed event for the timer.
        aTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent);

        // Set the Interval to 2 seconds (2000 milliseconds).
        aTimer.Interval = 2000;
        aTimer.Enabled = true;

        Console.WriteLine("Press the Enter key to exit the program.");
        Console.ReadLine();

        // If the timer is declared in a long-running method, use
        // KeepAlive to prevent garbage collection from occurring
        // before the method ends.
        //GC.KeepAlive(aTimer);
    }

    // Specify what you want to happen when the Elapsed event is 
    // raised.
    private static void OnTimedEvent(object source, ElapsedEventArgs e)
    {
        Console.WriteLine("The Elapsed event was raised at {0}", e.SignalTime);
    }
}

/* This code example produces output similar to the following:

Press the Enter key to exit the program.
The Elapsed event was raised at 5/20/2007 8:42:27 PM
The Elapsed event was raised at 5/20/2007 8:42:29 PM
The Elapsed event was raised at 5/20/2007 8:42:31 PM
...
 */

If you choose System.Threading.Timer, you can use as follows:

using System;
using System.Threading;

class TimerExample
{
    static void Main()
    {
        AutoResetEvent autoEvent     = new AutoResetEvent(false);
        StatusChecker  statusChecker = new StatusChecker(10);

        // Create the delegate that invokes methods for the timer.
        TimerCallback timerDelegate = 
            new TimerCallback(statusChecker.CheckStatus);

        // Create a timer that signals the delegate to invoke 
        // CheckStatus after one second, and every 1/4 second 
        // thereafter.
        Console.WriteLine("{0} Creating timer.\n", 
            DateTime.Now.ToString("h:mm:ss.fff"));
        Timer stateTimer = 
                new Timer(timerDelegate, autoEvent, 1000, 250);

        // When autoEvent signals, change the period to every 
        // 1/2 second.
        autoEvent.WaitOne(5000, false);
        stateTimer.Change(0, 500);
        Console.WriteLine("\nChanging period.\n");

        // When autoEvent signals the second time, dispose of 
        // the timer.
        autoEvent.WaitOne(5000, false);
        stateTimer.Dispose();
        Console.WriteLine("\nDestroying timer.");
    }
}

class StatusChecker
{
    int invokeCount, maxCount;

    public StatusChecker(int count)
    {
        invokeCount  = 0;
        maxCount = count;
    }

    // This method is called by the timer delegate.
    public void CheckStatus(Object stateInfo)
    {
        AutoResetEvent autoEvent = (AutoResetEvent)stateInfo;
        Console.WriteLine("{0} Checking status {1,2}.", 
            DateTime.Now.ToString("h:mm:ss.fff"), 
            (++invokeCount).ToString());

        if(invokeCount == maxCount)
        {
            // Reset the counter and signal Main.
            invokeCount  = 0;
            autoEvent.Set();
        }
    }
}

I've seen occasional problems with Eclipse forgetting that built-in classes (including Object and String) exist. The way I've resolved them is to:

• On the Project menu, turn off "Build Automatically"
• Quit and restart Eclipse
• On the Project menu, choose "Clean…" and clean all projects
• Turn "Build Automatically" back on and let it rebuild everything.

This seems to make Eclipse forget whatever incorrect cached information it had about the available classes.

If you need to return the table's total row count, you can use an alternative way to the SELECT COUNT(*) statement.

Because SELECT COUNT(*) makes a full table scan to return the row count, it can take very long time for a large table. You can use the sysindexes system table instead in this case. There is a ROWS column that contains the total row count for each table in your database. You can use the following select statement:

SELECT rows FROM sysindexes WHERE id = OBJECT_ID('table_name') AND indid < 2

This will drastically reduce the time your query takes.

Option(getObject) foreach (QueueManager add)

Was working on similar task and came across this query, by following few links and working on few exercises for nltk the below code worked for me like magic.

from nltk.tokenize import sent_tokenize 
  
text = "Hello everyone. Welcome to GeeksforGeeks. You are studying NLP article"
sent_tokenize(text) 

output:

['Hello everyone.',
 'Welcome to GeeksforGeeks.',
 'You are studying NLP article']

The filter function can also provide an interesting solution:

result = list(filter(lambda x: x.count(1) > 0, a))

which searches the tuples in the list a for any occurrences of 1. If the search is limited to the first element, the solution can be modified into:

result = list(filter(lambda x: x[0] == 1, a))

1)In your client side you can send you http.post request in string like below

var IndexInfo = JSON.stringify(this.scope.IndexTree);
this.$http.post('../../../api/EvaluationProcess/InsertEvaluationProcessInputType', "'" + IndexInfo + "'" ).then((response: any) => {}

2)Then in your web api controller you can deserialize it

public ApiResponce InsertEvaluationProcessInputType([FromBody]string IndexInfo)
    {
var des = (ApiReceivedListOfObjects<TempDistributedIndex>)Newtonsoft.Json.JsonConvert.DeserializeObject(DecryptedProcessInfo, typeof(ApiReceivedListOfObjects<TempDistributedIndex>));}

3)Your ApiReceivedListOfObjects class should be like below

public class ApiReceivedListOfObjects<T>
    {
        public List<T> element { get; set; }

    }

4)make sure that your serialized string (IndexInfo here) becomes like below structure before JsonConvert.DeserializeObject command in step 2

var resp = @"
    {
        ""element"": [
        {
            ""A"": ""A Jones"",
            ""B"": ""500015763""
        },
        {
            ""A"": ""B Smith"",
            ""B"": ""504986213""
        },
        {
            ""A"": ""C Brown"",
            ""B"": ""509034361""
        }
        ]
    }";

this worked for me fine!

Short answer

The device pixel ratio is the ratio between physical pixels and logical pixels. For instance, the iPhone 4 and iPhone 4S report a device pixel ratio of 2, because the physical linear resolution is double the logical linear resolution.

• Physical resolution: 960 x 640
• Logical resolution: 480 x 320

The formula is:

Where:

is the physical linear resolution

and:

is the logical linear resolution

Other devices report different device pixel ratios, including non-integer ones. For example, the Nokia Lumia 1020 reports 1.6667, the Samsumg Galaxy S4 reports 3, and the Apple iPhone 6 Plus reports 2.46 (source: dpilove). But this does not change anything in principle, as you should never design for any one specific device.

Discussion

The CSS "pixel" is not even defined as "one picture element on some screen", but rather as a non-linear angular measurement of viewing angle, which is approximately of an inch at arm's length. Source: CSS Absolute Lengths

This has lots of implications when it comes to web design, such as preparing high-definition image resources and carefully applying different images at different device pixel ratios. You wouldn't want to force a low-end device to download a very high resolution image, only to downscale it locally. You also don't want high-end devices to upscale low resolution images for a blurry user experience.

If you are stuck with bitmap images, to accommodate for many different device pixel ratios, you should use CSS Media Queries to provide different sets of resources for different groups of devices. Combine this with nice tricks like background-size: cover or explicitly set the background-size to percentage values.

Example

#element { background-image: url('lores.png'); }

@media only screen and (min-device-pixel-ratio: 2) {
    #element { background-image: url('hires.png'); }
}

@media only screen and (min-device-pixel-ratio: 3) {
    #element { background-image: url('superhires.png'); }
}

This way, each device type only loads the correct image resource. Also keep in mind that the px unit in CSS always operates on logical pixels.

A case for vector graphics

As more and more device types appear, it gets trickier to provide all of them with adequate bitmap resources. In CSS, media queries is currently the only way, and in HTML5, the picture element lets you use different sources for different media queries, but the support is still not 100 % since most web developers still have to support IE11 for a while more (source: caniuse).

If you need crisp images for icons, line-art, design elements that are not photos, you need to start thinking about SVG, which scales beautifully to all resolutions.

Sometimes .gitignore files don't work even though they're correct. The reason Git ignores files is that they are not added to the repository. If you added a file that you want to ignore before, it will be tracked by Git, and any skipping matching rules will be skipped. Git does this because the file is already part of the repository.

If you always want to the same transition animation for the activity

@Override

You could simply use XmlHttp (AJAX) to hit the required URL and the HTML response from the URL will be available in the responseText property. If it's not the same domain, your users will receive a browser alert saying something like "This page is trying to access a different domain. Do you want to allow this?"

The %#08X conversion must precede the value with 0X; that is required by the standard. There's no evidence in the standard that the # should alter the behaviour of the 08 part of the specification except that the 0X prefix is counted as part of the length (so you might want/need to use %#010X. If, like me, you like your hex presented as 0x1234CDEF, then you have to use 0x%08X to achieve the desired result. You could use %#.8X and that should also insert the leading zeroes.

Try variations on the following code:

#include <stdio.h>

int main(void)
{
    int j = 0;
    printf("0x%.8X = %#08X = %#.8X = %#010x\n", j, j, j, j);
    for (int i = 0; i < 8; i++)
    {
        j = (j << 4) | (i + 6);
        printf("0x%.8X = %#08X = %#.8X = %#010x\n", j, j, j, j);
    }
    return(0);
}

On an RHEL 5 machine, and also on Mac OS X (10.7.5), the output was:

0x00000000 = 00000000 = 00000000 = 0000000000
0x00000006 = 0X000006 = 0X00000006 = 0x00000006
0x00000067 = 0X000067 = 0X00000067 = 0x00000067
0x00000678 = 0X000678 = 0X00000678 = 0x00000678
0x00006789 = 0X006789 = 0X00006789 = 0x00006789
0x0006789A = 0X06789A = 0X0006789A = 0x0006789a
0x006789AB = 0X6789AB = 0X006789AB = 0x006789ab
0x06789ABC = 0X6789ABC = 0X06789ABC = 0x06789abc
0x6789ABCD = 0X6789ABCD = 0X6789ABCD = 0x6789abcd

I'm a little surprised at the treatment of 0; I'm not clear why the 0X prefix is omitted, but with two separate systems doing it, it must be standard. It confirms my prejudices against the # option.

The treatment of zero is according to the standard.

ISO/IEC 9899:2011 §7.21.6.1 The fprintf function

¶6 The flag characters and their meanings are:
...
# The result is converted to an "alternative form". ... For x (or X) conversion, a nonzero result has 0x (or 0X) prefixed to it. ...

(Emphasis added.)

Note that using %#X will use upper-case letters for the hex digits and 0X as the prefix; using %#x will use lower-case letters for the hex digits and 0x as the prefix. If you prefer 0x as the prefix and upper-case letters, you have to code the 0x separately: 0x%X. Other format modifiers can be added as needed, of course.

For printing addresses, use the <inttypes.h> header and the uintptr_t type and the PRIXPTR format macro:

#include <inttypes.h>
#include <stdio.h>

int main(void)
{
    void *address = &address;  // &address has type void ** but it converts to void *
    printf("Address 0x%.12" PRIXPTR "\n", (uintptr_t)address);
    return 0;
}

Example output:

Address 0x7FFEE5B29428

Choose your poison on the length — I find that a precision of 12 works well for addresses on a Mac running macOS. Combined with the . to specify the minimum precision (digits), it formats addresses reliably. If you set the precision to 16, the extra 4 digits are always 0 in my experience on the Mac, but there's certainly a case to be made for using 16 instead of 12 in portable 64-bit code (but you'd use 8 for 32-bit code).

jdk-7u80-macosx-x64.dmg fix this problem.

I'd suggest you to execute this SQL into your DB and check everytime when user inputs something.

  int a = srand(time(NULL));

The prototype for srand is void srand(unsigned int) (provided you included <stdlib.h>).
This means it returns nothing ... but you're using the value it returns (???) to assign, by initialization, to a.

Edit: this is what you need to do:

#include <stdlib.h> /* srand(), rand() */
#include <time.h>   /* time() */

#define ARRAY_SIZE 1024

void getdata(int arr[], int n)
{
    for (int i = 0; i < n; i++)
    {
        arr[i] = rand();
    }
}

int main(void)
{
    int arr[ARRAY_SIZE];
    srand(time(0));
    getdata(arr, ARRAY_SIZE);
    /* ... */
}

If you want to import a json file into Elasticsearch and create an index, use this Python script.

import json
from elasticsearch import Elasticsearch

es = Elasticsearch([{'host': 'localhost', 'port': 9200}])
i = 0
with open('el_dharan.json') as raw_data:
    json_docs = json.load(raw_data)
    for json_doc in json_docs:
            i = i + 1
            es.index(index='ind_dharan', doc_type='doc_dharan', id=i, body=json.dumps(json_doc))

With Hibernate you can create your own UserType. So thats what I did for this issue. Something as simple as this:

    public class BytesType implements org.hibernate.usertype.UserType {

         private final int[] SQL_TYPES = new int[] { java.sql.Types.VARBINARY };
     //...
    }

There of course is more to implement from extending your own UserType but I just wanted to throw that out there for anyone looking for other methods.

just a point,

numbers = [int(x) for x in numbers]

the list comprehension is more natural, while

numbers = map(int, numbers)

is faster.

Probably this will not matter in most cases

Apparently you need to use the list from Google at https://support.google.com/googleplay/answer/1727131

The APIs don't return anything I expect or anything in Settings. For my Motorola X this is what I get

   Build.MODEL = "XT1053"
   Build.BRAND = "motorola"
   Build.PRODUCT = "ghost"

Going to the page mentioned above "ghost" maps to Moto X. Seems like this could be a tad simpler...

As appsthatmatter says, in the layout something like:

<ListView android:id="@+id/listView" ... />
<TextView android:id="@+id/emptyElement" ... />

and in the linked Activity:

this.listView = (ListView) findViewById(R.id.listView);
this.listView.setEmptyView(findViewById(R.id.emptyElement));

Does also work with a GridView...

Answering the second part of your question,

Is there any standard or procedure one should follow to ensure there is no memory leak in the program.

Yes, there is. And this is one of the key differences between C and C++.

In C++, you should never call new or delete in your user code. RAII is a very commonly used technique, which pretty much solves the resource management problem. Every resource in your program (a resource is anything that has to be acquired, and then later on, released: file handles, network sockets, database connections, but also plain memory allocations, and in some cases, pairs of API calls (BeginX()/EndX(), LockY(), UnlockY()), should be wrapped in a class, where:

• the constructor acquires the resource (by calling new if the resource is a memroy allocation)
• the destructor releases the resource,
• copying and assignment is either prevented (by making the copy constructor and assignment operators private), or are implemented to work correctly (for example by cloning the underlying resource)

This class is then instantiated locally, on the stack, or as a class member, and not by calling new and storing a pointer.

You often don't need to define these classes yourself. The standard library containers behave in this way as well, so that any object stored into a std::vector gets freed when the vector is destroyed. So again, don't store a pointer into the container (which would require you to call new and delete), but rather the object itself (which gives you memory management for free). Likewise, smart pointer classes can be used to easily wrap objects that just have to be allocated with new, and control their lifetimes.

This means that when the object goes out of scope, it is automatically destroyed, and its resource released and cleaned up.

If you do this consistently throughout your code, you simply won't have any memory leaks. Everything that could get leaked is tied to a destructor which is guaranteed to be called when control leaves the scope in which the object was declared.

For those who don't want to resort to JavaScript, here's an image slicing example:

http://codepen.io/anon/pen/cbzrK

As you scale the window, the clown image will scale accordingly, and when it does, the nose of the clown remains hyperlinked.

I have also this problem when I do with XCode project what is exported from cordova framework. Resolution : You have to create Apple-ID and Provisioining-profile by yourself. Because Xcode seems to be unable to create it for you.

Based on the discussion in the comments (particularly from BalusC), it's probably not worth doing anything more complicated than this:

<script>var ctx = "${pageContext.request.contextPath}"</script>

Please try this.

       <Router>
          <div>
            <Route exact path="/" component={Home} />
            <Route path="/news" component={NewsFeed} />
          </div>
        </Router> 

            

Of you want to do it in a single line you can use

$("input").trigger(jQuery.Event('keydown', { which: '1'.charCodeAt(0) }));

Yes, definietly requests is great package to use in something related to HTTP requests. but we need to be careful with the encoding type of the incoming data as well below is an example which explains the difference

from requests import get

# case when the response is byte array
url = 'some_image_url'

response = get(url)
with open('output', 'wb') as file:
    file.write(response.content)


# case when the response is text
# Here unlikely if the reponse content is of type **iso-8859-1** we will have to override the response encoding
url = 'some_page_url'

response = get(url)
# override encoding by real educated guess as provided by chardet
r.encoding = r.apparent_encoding

with open('output', 'w', encoding='utf-8') as file:
    file.write(response.content)

As explained in this thread on the cxf-user mailing list, rather than having the CXFServlet load its own spring context from user-webservice-servlet.xml, you can just load the whole lot into the root context. Rename your existing user-webservice-servlet.xml to some other name (e.g. user-webservice-beans.xml) then change your contextConfigLocation parameter to something like:

<servlet>
  <servlet-name>myservlet</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
  <servlet-name>myservlet</servlet-name>
  <url-pattern>*.htm</url-pattern>
</servlet-mapping>

<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>
    /WEB-INF/applicationContext.xml
    /WEB-INF/user-webservice-beans.xml
  </param-value>
</context-param>

<servlet>
  <servlet-name>user-webservice</servlet-name>
  <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
  <load-on-startup>2</load-on-startup>
</servlet>

<servlet-mapping>
  <servlet-name>user-webservice</servlet-name>
  <url-pattern>/UserService/*</url-pattern>
</servlet-mapping>

This answer might not be 100% relevant to the question. But it does address the problem. I found this simple way of achieving this requirement. Code goes below:

<a href="@Url.Action("Display", "Customer")?custId={{cust.Id}}"></a>

In the above example {{cust.Id}} is an AngularJS variable. However one can replace it with a JavaScript variable.

I haven't tried passing multiple variables using this method but I'm hopeful that also can be appended to the Url if required.

Some more answers from the interwebs: "fix" the sensor (glue screen back on more, or clean it with alcohol, or blow it off with air sent through the headphone jack, tap on it, clean the screen, etc.).

Adjust (after some finding) setting in the "phone" app to disable proximity sensor use. No such setting in mine, that I could find. Proximity Screen Off Lite also didn't work, nor macrodroid.

Another option: root your phone and remove some files:

From root explorer or similar program delete these folders and file
/data/system/sensors
/data/misc/sensors
/persist/sensors/sns.reg

Or if you're truly desperate I suppose a totally different dialer system like TextNow or google hangouts dialer :|

I use the following code:

package main

import (
    "fmt"
    "time"
)

func main() {
    now := time.Now()
    fmt.Println("\nToday:", now)

    after := now.Add(1 * time.Minute)
    fmt.Println("\nAdd 1 Minute:", after)

    for {
        fmt.Println("test")
        time.Sleep(10 * time.Second)

        now = time.Now()

        if now.After(after) {
            break
        }
    }

    fmt.Println("done")
}

It is more simple and works fine to me.

Null Safe Methods :

Strings shorter than the max length returning the original string

String Right Extension Method

public static string Right(this string input, int count) =>
    String.Join("", (input + "").ToCharArray().Reverse().Take(count).Reverse());

String Left Extension Method

public static string Left(this string input, int count) =>
    String.Join("", (input + "").ToCharArray().Take(count));

Here is a simple solution in C. Assume interrupts are turned off for each function. No polymorphism & stuff, just common sense.

#define BUFSIZE 128
char buf[BUFSIZE];
char *pIn, *pOut, *pEnd;
char full;

// init
void buf_init()
{
    pIn = pOut = buf;       // init to any slot in buffer
    pEnd = &buf[BUFSIZE];   // past last valid slot in buffer
    full = 0;               // buffer is empty
}

// add char 'c' to buffer
int buf_put(char c)
{
    if (pIn == pOut  &&  full)
        return 0;           // buffer overrun

    *pIn++ = c;             // insert c into buffer
    if (pIn >= pEnd)        // end of circular buffer?
        pIn = buf;          // wrap around

    if (pIn == pOut)        // did we run into the output ptr?
        full = 1;           // can't add any more data into buffer
    return 1;               // all OK
}

// get a char from circular buffer
int buf_get(char *pc)
{
    if (pIn == pOut  &&  !full)
        return 0;           // buffer empty  FAIL

    *pc = *pOut++;              // pick up next char to be returned
    if (pOut >= pEnd)       // end of circular buffer?
        pOut = buf;         // wrap around

    full = 0;               // there is at least 1 slot
    return 1;               // *pc has the data to be returned
}

Maybe node.js has changed, but it seems there are some problems with the other solutions (using node v8.1.2):

1. You don't need to call file.close() in the finish event. Per default the fs.createWriteStream is set to autoClose: https://nodejs.org/api/fs.html#fs_fs_createwritestream_path_options
2. file.close() should be called on error. Maybe this is not needed when the file is deleted (unlink()), but normally it is: https://nodejs.org/api/stream.html#stream_readable_pipe_destination_options
3. Temp file is not deleted on statusCode !== 200
4. fs.unlink() without a callback is deprecated (outputs warning)
5. If dest file exists; it is overridden

Below is a modified solution (using ES6 and promises) which handles these problems.

const http = require("http");
const fs = require("fs");

function download(url, dest) {
    return new Promise((resolve, reject) => {
        const file = fs.createWriteStream(dest, { flags: "wx" });

        const request = http.get(url, response => {
            if (response.statusCode === 200) {
                response.pipe(file);
            } else {
                file.close();
                fs.unlink(dest, () => {}); // Delete temp file
                reject(`Server responded with ${response.statusCode}: ${response.statusMessage}`);
            }
        });

        request.on("error", err => {
            file.close();
            fs.unlink(dest, () => {}); // Delete temp file
            reject(err.message);
        });

        file.on("finish", () => {
            resolve();
        });

        file.on("error", err => {
            file.close();

            if (err.code === "EEXIST") {
                reject("File already exists");
            } else {
                fs.unlink(dest, () => {}); // Delete temp file
                reject(err.message);
            }
        });
    });
}

A different base R alternative would be to first order by id and stopSequence, split them based on id and for every id we select only the first and last index and subset the dataframe using those indices.

df[sapply(with(df, split(order(id, stopSequence), id)), function(x) 
                   c(x[1], x[length(x)])), ]


#  id stopId stopSequence
#1  1      a            1
#3  1      c            3
#5  2      b            1
#6  2      c            4
#8  3      b            1
#7  3      a            3

Or similar using by

df[unlist(with(df, by(order(id, stopSequence), id, function(x) 
                   c(x[1], x[length(x)])))), ]

You can't, but you can use BETWEEN

SELECT job FROM mytable WHERE id BETWEEN 10 AND 15

Note that BETWEEN is inclusive, and will include items with both id 10 and 15.

If you do not want inclusion, you'll have to fall back to using the > and < operators.

SELECT job FROM mytable WHERE id > 10 AND id < 15

It is not always so simple and sometimes the alignment must be defined in the container and not in the Button element itself !

For your case, the solution would be

<div style="text-align:right; width:100%; padding:0;">
    <input type="button" value="Click Me"/>
</div>

I have taken care to specify width=100% to be sure that <div> take full width of his container.

I have also added padding:0 to avoid before and after space as with <p> element.

I can say that if <div> is defined in a FSF/Primefaces table's footer, the float:right don't work correctly because the Button height will become higher than the footer height !

In this Primefaces situation, the only acceptable solution is to use text-align:right in container.

With this solution, if you have 6 Buttons to align at right, you must only specify this alignment in container :-)

<div style="text-align:right; width:100%; padding:0;">
    <input type="button" value="Click Me 1"/>
    <input type="button" value="Click Me 2"/>
    <input type="button" value="Click Me 3"/>
    <input type="button" value="Click Me 4"/>
    <input type="button" value="Click Me 5"/>
    <input type="button" value="Click Me 6"/>
</div>

On Debian/Ubuntu:

aptitude install python-numpy

On Windows, download the installer:

On other systems, download the tar.gz and run the following:

$ tar xfz numpy-n.m.tar.gz
$ cd numpy-n.m
$ python setup.py install

Yes you can do that by just creating a BroadcastReceiver that calls your Service when your Application boots. Here is a complete answer given by me.
Android - Start service on boot

If you don't want any icon/launcher for you Application you can do that also, just don't create any Activity with

<intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

Just declare your Service as declared normally.

if you invoke .equals() on null you will get NullPointerException

So it is always advisble to check nullity before invoking method where ever it applies

if(str!=null && str.equals("hi")){
 //str contains hi
}  

Also See

• difference-between-equals-and == in Java

Try to use getActivity(); This will solve your problem.

Here's a good class :

public class Palindrome {

  public static boolean isPalindrome(String stringToTest) {
    String workingCopy = removeJunk(stringToTest);
    String reversedCopy = reverse(workingCopy);

    return reversedCopy.equalsIgnoreCase(workingCopy);
  }

  protected static String removeJunk(String string) {
    int i, len = string.length();
    StringBuffer dest = new StringBuffer(len);
    char c;

    for (i = (len - 1); i >= 0; i--) {
      c = string.charAt(i);
      if (Character.isLetterOrDigit(c)) {
        dest.append(c);
      }
    }

    return dest.toString();
  }

  protected static String reverse(String string) {
    StringBuffer sb = new StringBuffer(string);

    return sb.reverse().toString();
  }

  public static void main(String[] args) {
    String string = "Madam, I'm Adam.";

    System.out.println();
    System.out.println("Testing whether the following "
        + "string is a palindrome:");
    System.out.println("    " + string);
    System.out.println();

    if (isPalindrome(string)) {
      System.out.println("It IS a palindrome!");
    } else {
      System.out.println("It is NOT a palindrome!");
    }
    System.out.println();
  }
}

Enjoy.

I know its long after this question was asked and answered - and I am sure that the accepted solution is right, but the purist in me would rather not add an extra element to the SVG when I can achieve the same or similar with straight CSS.

Whilst it is true that you cannot style the g container element in most ways - you can definitely add an outline to it and style that - even changing it on hover of the g - as shown in the snippet.

It not as good in one regard as the other way - you can put the outline box around the grouped elements - but not a background behind it. Sot its not perfect and won't solve the issue for everyone - but I would rather have the outline done with css than have to add extra elements to the code just to provide styling hooks.

And this method definitely allows you to show grouping of related objects in your SVG's.

Just a thought.

g {_x000D_
    outline: solid 3px blue;_x000D_
    outline-offset: 5px;_x000D_

I think it depends on what you mean by refresh. Do you mean that the GUI display should be refreshed, or do you mean that the child views should be refreshed such that you can programatically call getChildAt(int) and get the view corresponding to what is in the Adapter.

If you want the GUI display refreshed, then call notifyDataSetChanged() on the adapter. The GUI will be refreshed when next redrawn.

If you want to be able to call getChildAt(int) and get a view that reflects what is what is in the adapter, then call to layoutChildren(). This will cause the child view to be reconstructed from the adapter data.

like this

css

textarea {

overflow:scroll;
height:100px;
}

Omitting the html, head, and body tags is certainly allowed by the HTML specs. The underlying reason is that browsers have always sought to be consistent with existing web pages, and the very early versions of HTML didn't define those elements. When HTML 2.0 first did, it was done in a way that the tags would be inferred when missing.

I often find it convenient to omit the tags when prototyping and especially when writing test cases as it helps keep the mark-up focused on the test in question. The inference process should create the elements in exactly the manner that you see in Firebug, and browsers are pretty consistent in doing that.

But...

IE has at least one known bug in this area. Even IE9 exhibits this. Suppose the markup is this:

<!DOCTYPE html>
<title>Test case</title>
<form action='#'>
   <input name="var1">
</form>

You should (and do in other browsers) get a DOM that looks like this:

HTML
    HEAD
        TITLE
    BODY
        FORM action="#"
            INPUT name="var1"

But in IE you get this:

HTML
    HEAD
       TITLE
       FORM action="#"
           BODY
               INPUT name="var1"
    BODY

See it for yourself.

This bug seems limited to the form start tag preceding any text content and any body start tag.

In SQL Server row_numer() is a powerful function that can get result easily as below

select Person,[group],age
from
(
select * ,row_number() over(partition by [group] order by age desc) rn
from mytable
) t
where rn <= 2

Use div.section > div.

Better yet, use an <h1> tag for the heading and div.section h1 in your CSS, so as to support older browsers (that don't know about the >) and keep your markup semantic.

Your database may be corrupt. Try to check if mysql.user exists:

use mysql;
select * from user;

If these are missing you can try recreating the tables by using

mysql_install_db

or you may have to clean (completely remove it) and reinstall MySQL.

$("#id1 p:contains('dog')").html("doll");

that'll do it.

This is not the most robust solution - but if you're just looking to create a partitioned rank on a field with only a few different values, it may not be unwieldily to use some case when logic with as many variables as you require.

Something like this has worked for me in the past:

SELECT t.*, 
   CASE WHEN <partition_field> = @rownum1 := @rownum1 + 1 
     WHEN <partition_field> = @rownum2 := @rownum2 + 1 
     ...
     END AS rank
FROM YOUR_TABLE t, 
   (SELECT @rownum1 := 0) r1, (SELECT @rownum2 := 0) r2
ORDER BY <rank_order_by_field>
;

Hope that makes sense / helps!

I like Microsoft's XML Notepad 2007, but I don't know how it handles very large files, sorry.

I was having the same problem, I had a ComboBox followed by a ListBox in a StackPanel and the scroll bar for the ListBox was not showing up. I solved this by putting the two in a DockPanel instead. I set the ComboBox DockPanel.Dock="Top" and let the ListBox fill the remaining space.

I agree this one isn't immediate when you first look at it, but it's fairly simple when you get down to it.

Base case: your tower is of size 1. So you can do it in one move, from source directly to dest.

Recursive case: your tower is of size n > 1. So you move the top tower of size n-1 to an extra peg (by), move the bottom "tower" of size 1 to the destination peg, and move the top tower from by to dest.

So with a simple case, you have a tower of height 2:

 _|_    |     |
__|__   |     |
===== ===== =====

First step: move the top tower of 2-1 (=1) to the extra peg (the middle one, lets say).

  |     |     |
__|__  _|_    |
===== ===== =====

Next: move the bottom disc to the destination:

  |     |     |
  |    _|_  __|__
===== ===== =====

And finally, move the top tower of (2-1)=1 to the destination.

  |     |    _|_
  |     |   __|__
===== ===== =====

If you think about it, even if the tower were 3 or more, there will always be an empty extra peg, or a peg with all larger discs, for the recursion to use when swapping towers around.

This will translate to a where in clause in Linq to SQL...

var myInClause = new string[] {"One", "Two", "Three"};

var results = from x in MyTable
              where myInClause.Contains(x.SomeColumn)
              select x;
// OR
var results = MyTable.Where(x => myInClause.Contains(x.SomeColumn));

In the case of your query, you could do something like this...

var results = from states in _objectdatasource.StateList()
              where listofcountrycodes.Contains(states.CountryCode)
              select new State
              {
                  StateName = states.StateName
              };
// OR
var results = _objectdatasource.StateList()
                  .Where(s => listofcountrycodes.Contains(s.CountryCode))
                  .Select(s => new State { StateName = s.StateName});

Suppose you have a DataFrame and you want to do some modification on the fields data by converting it to RDD[Row].

val aRdd = aDF.map(x=>Row(x.getAs[Long]("id"),x.getAs[List[String]]("role").head))

To convert back to DataFrame from RDD we need to define the structure type of the RDD.

If the datatype was Long then it will become as LongType in structure.

If String then StringType in structure.

val aStruct = new StructType(Array(StructField("id",LongType,nullable = true),StructField("role",StringType,nullable = true)))

Now you can convert the RDD to DataFrame using the createDataFrame method.

val aNamedDF = sqlContext.createDataFrame(aRdd,aStruct)

If you want a css only solution you can use active

.crossRotate:active {
   transform: rotate(45deg);
   -webkit-transform: rotate(45deg);
   -ms-transform: rotate(45deg);
}

But the transformation will not persist when the activity moves. For that you need javascript (jquery click and css is the cleanest IMO).

$( ".crossRotate" ).click(function() {
    if (  $( this ).css( "transform" ) == 'none' ){
        $(this).css("transform","rotate(45deg)");
    } else {
        $(this).css("transform","" );
    }
});

This is a pretty straight forward way of having HTML5 perform validation for any form, while still having modern JS control over the form. The only caveat is the submit button must be inside the <form>.

html

<form id="newUserForm" name="create">
Email<input type="email" name="username" id="username" size="25" required>
Phone<input type="tel" id="phone" name="phone" pattern="(?:\(\d{3}\)|\d{3})[- ]?\d{3}[- ]?\d{4}" size="12" maxlength="12" required>
<input id="submit" type="submit" value="Create Account" >
</form>

js

// bind in ready() function
jQuery( "#submit" ).click( newAcctSubmit );

function newAcctSubmit()
{
  var myForm = jQuery( "#newUserForm" );

  // html 5 is doing the form validation for us,
  // so no need here (but backend will need to still for security)
  if ( ! myForm[0].checkValidity() )
  {
    // bonk! failed to validate, so return true which lets the
    // browser show native validation messages to the user
    return true;
  }

  // post form with jQuery or whatever you want to do with a valid form!
  var formVars = myForm.serialize();
  etc...
}

There is relevant info on a configuration of CSRF with respect to API controllers on api.rubyonrails.org:

?

It's important to remember that XML or JSON requests are also affected and if you're building an API you should change forgery protection method in ApplicationController (by default: :exception):

class ApplicationController < ActionController::Base
  protect_from_forgery unless: -> { request.format.json? }
end

We may want to disable CSRF protection for APIs since they are typically designed to be state-less. That is, the request API client will handle the session for you instead of Rails.

As always, I recommend reading this article about date and time in Java so that you understand it.

The basic idea is that 'under the hood' everything is done in UTC milliseconds since the epoch. This means it is easiest if you operate without using time zones at all, with the exception of String formatting for the user.

Therefore I would skip most of the steps you have suggested.

1. Set the time on an object (Date, Calendar etc).
2. Set the time zone on a formatter object.
3. Return a String from the formatter.

Alternatively, you can use Joda time. I have heard it is a much more intuitive datetime API.

It seems possible your class may have been using pre-standard C++. An easy way to tell, is to look at your old programs and check, do you see:

#include <iostream.h>

or

#include <iostream>

The former is pre-standard, and you'll be able to just say cout as opposed to std::cout without anything additional. You can get the same behavior in standard C++ by adding

using std::cout;

or

using namespace std;

Just one idea, anyway.

Mavroprovato's answer reports more than only the listening ports. Listening ports are sockets without a peer. The following Perl program reports only the listening ports. It works for me on SunOS 5.10.

#! /usr/bin/env perl
##
## Search the processes which are listening on the given port.
##
## For SunOS 5.10.
##

use strict;
use warnings;

die "Port missing" unless $#ARGV >= 0;
my $port = int($ARGV[0]);
die "Invalid port" unless $port > 0;

my @pids;
map { push @pids, $_ if $_ > 0; } map { int($_) } `ls /proc`;

foreach my $pid (@pids) {
    open (PF, "pfiles $pid 2>/dev/null |") 
        || warn "Can not read pfiles $pid";
    $_ = <PF>;
    my $fd;
    my $type;
    my $sockname;
    my $peername;
    my $report = sub {
        if (defined $fd) {
            if (defined $sockname && ! defined $peername) {
                print "$pid $type $sockname\n"; } } };
    while (<PF>) {
        if (/^\s*(\d+):.*$/) {
            &$report();
            $fd = int ($1);
            undef $type;
            undef $sockname;
            undef $peername; }
        elsif (/(SOCK_DGRAM|SOCK_STREAM)/) { $type = $1; }
        elsif (/sockname: AF_INET[6]? (.*)  port: $port/) {
            $sockname = $1; }
        elsif (/peername: AF_INET/) { $peername = 1; } }
    &$report();
    close (PF); }

Try this

select * from mytable
where p1 not like '%[^0-9]%' and substring(p1,1,1)='5'

Of course, you'll need to adjust the substring value, but the rest should work...

Correct me if I'm mistaken, but the previous example, I believe, is just slightly out of sync with the latest version of James Newton's Json.NET library.

var o = JObject.Parse(stringFullOfJson);
var page = (int)o["page"];
var totalPages = (int)o["total_pages"];

The problem is not with the Event type, but that the EventTarget interface in typescript only has 3 methods:

interface EventTarget {
    addEventListener(type: string, listener: EventListenerOrEventListenerObject, useCapture?: boolean): void;
    dispatchEvent(evt: Event): boolean;
    removeEventListener(type: string, listener: EventListenerOrEventListenerObject, useCapture?: boolean): void;
}

interface SyntheticEvent {
    bubbles: boolean;
    cancelable: boolean;
    currentTarget: EventTarget;
    defaultPrevented: boolean;
    eventPhase: number;
    isTrusted: boolean;
    nativeEvent: Event;
    preventDefault(): void;
    stopPropagation(): void;
    target: EventTarget;
    timeStamp: Date;
    type: string;
}

So it is correct that name and value don't exist on EventTarget. What you need to do is to cast the target to the specific element type with the properties you need. In this case it will be HTMLInputElement.

update = (e: React.SyntheticEvent): void => {
    let target = e.target as HTMLInputElement;
    this.props.login[target.name] = target.value;
}

Also for events instead of React.SyntheticEvent, you can also type them as following: Event, MouseEvent, KeyboardEvent...etc, depends on the use case of the handler.

The best way to see all these type definitions is to checkout the .d.ts files from both typescript & react.
