No -P needed; -E is sufficient:

grep -E '(^|\s)abc(\s|$)' 

or even without -E:

grep '\(^\|\s\)abc\(\s\|$\)' 

in my case the problem was the Resource statement in the user access policy.

First we had "Resource": "arn:aws:s3:::BUCKET_NAME", but in order to have access to objects within a bucket you need a /* at the end: "Resource": "arn:aws:s3:::BUCKET_NAME/*"

From the AWS documentation:

Bucket access permissions specify which users are allowed access to the objects in a bucket and which types of access they have. Object access permissions specify which users are allowed access to the object and which types of access they have. For example, one user might have only read permission, while another might have read and write permissions.

I also got the same exception:

I tried the following steps:

1. In Eclipse> Project > Clean. (The Exception remained)

2. I ran another project(The testng.xml ran successfully)

After running another project, I ran the project in which I was getting the Exception, and fortunately it worked for me, with no errors.

Check this out:

One of the reasons for this error is the use of the jaxb implementation from the jdk. I am not sure why such a problem can appear in pretty simple xml parsing situations. You may use the latest version of the jaxb library from a public maven repository:

http://mvnrepository.com

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.2.12</version>
</dependency>

 select * FROM doc_tab
    PIVOT
    (
    Min(document_id)
    FOR document_type IN ('Voters ID','Pan card','Drivers licence')
    ) 

outputs as this

When you have everything #included, an unresolved external symbol is often a missing * or & in the declaration or definition of a function.

This is a simple benchmark:

require 'benchmark'

"test123" =~ /1/
=> 4
Benchmark.measure{ 1000000.times { "test123" =~ /1/ } }
=>   0.610000   0.000000   0.610000 (  0.578133)

"test123"[/1/]
=> "1"
Benchmark.measure{ 1000000.times { "test123"[/1/] } }
=>   0.718000   0.000000   0.718000 (  0.750010)

irb(main):019:0> "test123".match(/1/)
=> #<MatchData "1">
Benchmark.measure{ 1000000.times { "test123".match(/1/) } }
=>   1.703000   0.000000   1.703000 (  1.578146)

So =~ is faster but it depends what you want to have as a returned value. If you just want to check if the text contains a regex or not use =~

2012-04-20 11:14:32.617:WARN:oejx.XmlParser:FATAL@file:/C:/Users/***/workspace/Test/WEB-INF/web.xml line:1 col:7 : org.xml.sax.SAXParseException: The processing instruction target matching "[xX][mM][lL]" is not allowed.

You Log says, that you web.xml is malformed. Line 1, colum 7. It may be a UTF-8 Byte-Order-Marker

Try to verify, that your xml is wellformed and does not have a BOM. Java doesn't use BOMs.

In server applications the stacktrace blows up your stdout/stderr file. It may become larger and larger and is filled with useless data because usually you have no context and no timestamp and so on.

e.g. catalina.out when using tomcat as container

You could also do a for loop as you would for an array but instead of array[i] you would use list.get(i)

for (int i = 0; i < list.size(); i++) {
    System.out.println(list.get(i));
}

I faced the same issue. Our application running on four application servers and due to invalid schema location mentioned on one of the web service WSDL, hung threads are generated on the servers . The appliucations got down frequently. After corrected the schema Location , the issue got resolved.

1st Reason could be the ending tag of your application's web.xml file which could not have been closed properly.

web.xml might be ending with <web-app>, but must end with </web-app>

2nd Reason which worked in my case could be the lib folder of your tomcat must contain the supporting jar file of your database.

    Inside a character class: ^ - [ ]

BRE/ed/grep/sed

    Outside a character class: . ^ $ * [ \
    Inside a character class: ^ - [ ]
    For literals, don't escape: + ? ( ) { } |
    For standard regex behavior, escape: \+ \? \( \) \{ \} \|

Notes

• If unsure about a specific character, it can be escaped like \xFF
• Alphanumeric characters cannot be escaped with a backslash
• Arbitrary symbols can be escaped with a backslash in PCRE, but not BRE/ERE (they must only be escaped when required). For PCRE ] - only need escaping within a character class, but I kept them in a single list for simplicity
• Quoted expression strings must also have the surrounding quote characters escaped, and often with backslashes doubled-up (like "(\")(/)(\\.)" versus /(")(\/)(\.)/ in JavaScript)
• Aside from escapes, different regex implementations may support different modifiers, character classes, anchors, quantifiers, and other features. For more details, check out regular-expressions.info, or use regex101.com to test your expressions live

The easiest to use XML parser for Python is ElementTree (as of 2.5x and above it is in the standard library xml.etree.ElementTree). I don't think there is anything that does exactly what you want out of the box. It would be pretty trivial to write something to do what you want using ElementTree, but why convert to a dictionary, and why not just use ElementTree directly.

I found that just using the connectivity package was not enough to tell if the internet was available or not. In Android it only checks if there is WIFI or if mobile data is turned on, it does not check for an actual internet connection . During my testing, even with no mobile signal ConnectivityResult.mobile would return true.

With IOS my testing found that the connectivity plugin does correctly detect if there is an internet connection when the phone has no signal, the issue was only with Android.

The solution I found was to use the data_connection_checker package along with the connectivity package. This just makes sure there is an internet connection by making requests to a few reliable addresses, the default timeout for the check is around 10 seconds.

My finished isInternet function looked a bit like this:

  Future<bool> isInternet() async {
    var connectivityResult = await (Connectivity().checkConnectivity());
    if (connectivityResult == ConnectivityResult.mobile) {
      // I am connected to a mobile network, make sure there is actually a net connection.
      if (await DataConnectionChecker().hasConnection) {
        // Mobile data detected & internet connection confirmed.
        return true;
      } else {
        // Mobile data detected but no internet connection found.
        return false;
      }
    } else if (connectivityResult == ConnectivityResult.wifi) {
      // I am connected to a WIFI network, make sure there is actually a net connection.
      if (await DataConnectionChecker().hasConnection) {
        // Wifi detected & internet connection confirmed.
        return true;
      } else {
        // Wifi detected but no internet connection found.
        return false;
      }
    } else {
      // Neither mobile data or WIFI detected, not internet connection found.
      return false;
    }
  }

The if (await DataConnectionChecker().hasConnection) part is the same for both mobile and wifi connections and should probably be moved to a separate function. I've not done that here to leave it more readable.

This is my first Stack Overflow answer, hope it helps someone.

if you really wanted to do that you could then do

In Sql Server 2012,

 select getdate()-DATEPART(day, getdate())+1

 select DATEADD(Month,1,getdate())-DATEPART(day, getdate())

Check out angular-ui, specifically, route checking: http://angular-ui.github.io/ui-utils/

SELECT CAST(FLOOR(CAST(GETDATE() AS float)) as datetime)

or

SELECT CONVERT(datetime,FLOOR(CONVERT(float,GETDATE())))

I was also getting this issue also however none of the above worked for me as I was using a custom binding (for BinaryXML) after an long time digging I found the answer here :-

I created a base class for creating string-valued enums in .NET. It is just one C# file that you can copy & paste into your projects, or install via NuGet package named StringEnum.

Usage:

///<completionlist cref="HexColor"/> 
class HexColor : StringEnum<HexColor>
{
    public static readonly HexColor Blue = New("#FF0000");
    public static readonly HexColor Green = New("#00FF00");
    public static readonly HexColor Red = New("#000FF");
}

Features

• Your StringEnum looks somewhat similar to a regular enum:

    // Static Parse Method
    HexColor.Parse("#FF0000") // => HexColor.Red
    HexColor.Parse("#ff0000", caseSensitive: false) // => HexColor.Red
    HexColor.Parse("invalid") // => throws InvalidOperationException

    // Static TryParse method.
    HexColor.TryParse("#FF0000") // => HexColor.Red
    HexColor.TryParse("#ff0000", caseSensitive: false) // => HexColor.Red
    HexColor.TryParse("invalid") // => null

    // Parse and TryParse returns the preexistent instances
    object.ReferenceEquals(HexColor.Parse("#FF0000"), HexColor.Red) // => true

    // Conversion from your `StringEnum` to `string`
    string myString1 = HexColor.Red.ToString(); // => "#FF0000"
    string myString2 = HexColor.Red; // => "#FF0000" (implicit cast)

• Intellisense will suggest the enum name if the class is annotated with the xml comment <completitionlist>. (Works in both C# and VB): i.e.

Instalation

Either:

• Install latest StringEnum NuGet package, which is based on .Net Standard 1.0 so it runs on .Net Core >= 1.0, .Net Framework >= 4.5, Mono >= 4.6, etc.
• Or paste the following StringEnum base class to your project. (latest version)

    public abstract class StringEnum<T> : IEquatable<T> where T : StringEnum<T>, new()
    {
        protected string Value;
        private static IList<T> valueList = new List<T>();
        protected static T New(string value)
        {
            if (value == null)
                return null; // the null-valued instance is null.

            var result = new T() { Value = value };
            valueList.Add(result);
            return result;
        }

        public static implicit operator string(StringEnum<T> enumValue) => enumValue.Value;
        public override string ToString() => Value;

        public static bool operator !=(StringEnum<T> o1, StringEnum<T> o2) => o1?.Value != o2?.Value;
        public static bool operator ==(StringEnum<T> o1, StringEnum<T> o2) => o1?.Value == o2?.Value;

        public override bool Equals(object other) => this.Value.Equals((other as T)?.Value ?? (other as string));
        bool IEquatable<T>.Equals(T other) => this.Value.Equals(other.Value);
        public override int GetHashCode() => Value.GetHashCode();

        /// <summary>
        /// Parse the <paramref name="value"/> specified and returns a valid <typeparamref name="T"/> or else throws InvalidOperationException.
        /// </summary>
        /// <param name="value">The string value representad by an instance of <typeparamref name="T"/>. Matches by string value, not by the member name.</param>
        /// <param name="caseSensitive">If true, the strings must match case sensitivity.</param>
        public static T Parse(string value, bool caseSensitive = false)
        {
            var result = TryParse(value, caseSensitive);
            if (result == null)
                throw new InvalidOperationException((value == null ? "null" : $"'{value}'") + $" is not a valid {typeof(T).Name}");

            return result;
        }

        /// <summary>
        /// Parse the <paramref name="value"/> specified and returns a valid <typeparamref name="T"/> or else returns null.
        /// </summary>
        /// <param name="value">The string value representad by an instance of <typeparamref name="T"/>. Matches by string value, not by the member name.</param>
        /// <param name="caseSensitive">If true, the strings must match case sensitivity.</param>
        public static T TryParse(string value, bool caseSensitive = false)
        {
            if (value == null) return null;
            if (valueList.Count == 0) System.Runtime.CompilerServices.RuntimeHelpers.RunClassConstructor(typeof(T).TypeHandle); // force static fields initialization
            var field = valueList.FirstOrDefault(f => f.Value.Equals(value,
                    caseSensitive ? StringComparison.Ordinal
                                  : StringComparison.OrdinalIgnoreCase));
            // Not using InvariantCulture because it's only supported in NETStandard >= 2.0

            if (field == null)
                return null;

            return field;
        }
    }

• For Newtonsoft.Json serialization support, copy this extended version instead. StringEnum.cs

I realized after the fact that this code is similar to Ben's answer. I sincerely wrote it from scratch. However I think it has a few extras, like the <completitionlist> hack, the resulting class looks more like an Enum, no use of reflection on Parse(), the NuGet package and repo where I will hopefully address incoming issues and feedback.

It is impossible, and unnecessary, to know the motivation for using " in element content, but possible motives include: misunderstanding of HTML rules; use of software that generates such code (probably because its author thought it was “safer”); and misunderstanding of the meaning of ": many people seem to think it produces “smart quotes” (they apparently never looked at the actual results).

Anyway, there is never any need to use " in element content in HTML (XHTML or any other HTML version). There is nothing in any HTML specification that would assign any special meaning to the plain character " there.

As the question says, it has its role in attribute values, but even in them, it is mostly simpler to just use single quotes as delimiters if the value contains a double quote, e.g. alt='Greeting: "Hello, World!"' or, if you are allowed to correct errors in natural language texts, to use proper quotation marks, e.g. alt="Greeting: “Hello, World!”"

But still I am not sure how it works?

Let's say an entity MyEntity has an annotated version property:

@Entity
public class MyEntity implements Serializable {    

    @Id
    @GeneratedValue
    private Long id;

    private String name;

    @Version
    private Long version;

    //...
}

On update, the field annotated with @Version will be incremented and added to the WHERE clause, something like this:

UPDATE MYENTITY SET ..., VERSION = VERSION + 1 WHERE ((ID = ?) AND (VERSION = ?))

If the WHERE clause fails to match a record (because the same entity has already been updated by another thread), then the persistence provider will throw an OptimisticLockException.

Does it mean that we should declare our version field as final

No but you could consider making the setter protected as you're not supposed to call it.

With numpy:

In [128]: list_a = np.array([1, 2, 4, 6])
In [129]: filter = np.array([True, False, True, False])
In [130]: list_a[filter]

Out[130]: array([1, 4])

or see Alex Szatmary's answer if list_a can be a numpy array but not filter

Numpy usually gives you a big speed boost as well

In [133]: list_a = [1, 2, 4, 6]*10000
In [134]: fil = [True, False, True, False]*10000
In [135]: list_a_np = np.array(list_a)
In [136]: fil_np = np.array(fil)

In [139]: %timeit list(itertools.compress(list_a, fil))
1000 loops, best of 3: 625 us per loop

In [140]: %timeit list_a_np[fil_np]
10000 loops, best of 3: 173 us per loop

One of these will work...

First, make sure you understand, if you need to use Secure FTP (=FTPS, as per your text) or SFTP (as per tag you have used).

Neither is supported by Windows command-line ftp.exe. As you have suggested, you can use WinSCP. It supports both FTPS and SFTP.

Using WinSCP, your batch file would look like (for SFTP):

echo open sftp://ftp_user:[email protected] -hostkey="server's hostkey" >> ftpcmd.dat
echo put c:\directory\%1-export-%date%.csv >> ftpcmd.dat
echo exit >> ftpcmd.dat
winscp.com /script=ftpcmd.dat
del ftpcmd.dat

And the batch file:

winscp.com /log=ftpcmd.log /script=ftpcmd.dat /parameter %1 %date%

Though using all capabilities of WinSCP (particularly providing commands directly on command-line and the %TIMESTAMP% syntax), the batch file simplifies to:

winscp.com /log=ftpcmd.log /command ^
    "open sftp://ftp_user:[email protected] -hostkey=""server's hostkey""" ^
    "put c:\directory\%1-export-%%TIMESTAMP#yyyymmdd%%.csv" ^
    "exit"

For the purpose of -hostkey switch, see verifying the host key in script.

Easier than assembling the script/batch file manually is to setup and test the connection settings in WinSCP GUI and then have it generate the script or batch file for you:

All you need to tweak is the source file name (use the %TIMESTAMP% syntax as shown previously) and the path to the log file.

For FTPS, replace the sftp:// in the open command with ftpes:// (explicit TLS/SSL) or ftps:// (implicit TLS/SSL). Remove the -hostkey switch.

winscp.com /log=ftpcmd.log /command ^
    "open ftps://ftp_user:[email protected] -explicit" ^
    "put c:\directory\%1-export-%%TIMESTAMP#yyyymmdd%%.csv" ^
    "exit"

You may need to add the -certificate switch, if your server's certificate is not issued by a trusted authority.

Again, as with the SFTP, easier is to setup and test the connection settings in WinSCP GUI and then have it generate the script or batch file for you.

See a complete conversion guide from ftp.exe to WinSCP.

You should also read the Guide to automating file transfers to FTP server or SFTP server.

Note to using %TIMESTAMP#yyyymmdd% instead of %date%: A format of %date% variable value is locale-specific. So make sure you test the script on the same locale you are actually going to use the script on. For example on my Czech locale the %date% resolves to ct 06. 11. 2014, what might be problematic when used as a part of a file name.

For this reason WinSCP supports (locale-neutral) timestamp formatting natively. For example %TIMESTAMP#yyyymmdd% resolves to 20170515 on any locale.

(I'm the author of WinSCP)

We did it like this:

from p in Products                         
join bp in BaseProducts on p.BaseProductId equals bp.Id                    
where !string.IsNullOrEmpty(p.SomeId) && p.LastPublished >= lastDate                         
group new { p, bp } by new { p.SomeId } into pg    
let firstproductgroup = pg.FirstOrDefault()
let product = firstproductgroup.p
let baseproduct = firstproductgroup.bp
let minprice = pg.Min(m => m.p.Price)
let maxprice = pg.Max(m => m.p.Price)
select new ProductPriceMinMax
{
SomeId = product.SomeId,
BaseProductName = baseproduct.Name,
CountryCode = product.CountryCode,
MinPrice = minprice, 
MaxPrice = maxprice
};

EDIT: we used the version of AakashM, because it has better performance

here is the impressive solution.

funct alphabet_count_mapper:

for each word in the file/list

1.create a dictionary of alphabets/characters with initial count as 0.

2.keep count of all the alphabets in the word and increment the count in the above alphabet dict.

3.create alphabet count dict and return the tuple of the values of alphabet dict.

funct anagram_counter:

1.create a dictionary with alphabet count tuple as key and the count of the number of occurences against it.

2.iterate over the above dict and if the value > 1, add the value to the anagram count.

    import sys
    words_count_map_dict = {}
    fobj = open(sys.argv[1],"r")
    words = fobj.read().split('\n')[:-1]

    def alphabet_count_mapper(word):
        alpha_count_dict = dict(zip('abcdefghijklmnopqrstuvwxyz',[0]*26))
        for alpha in word:
            if alpha in alpha_count_dict.keys():
                alpha_count_dict[alpha] += 1
            else:
                alpha_count_dict.update(dict(alpha=0))
        return tuple(alpha_count_dict.values())

    def anagram_counter(words):
        anagram_count = 0
        for word in words:
            temp_mapper = alphabet_count_mapper(word)
            if temp_mapper in words_count_map_dict.keys():
                words_count_map_dict[temp_mapper] += 1
            else:
                words_count_map_dict.update({temp_mapper:1})
        for val in words_count_map_dict.values():
            if val > 1:
                anagram_count += val
        return anagram_count


    print anagram_counter(words)

run it with file path as command line argument

.prop('disabled') will return a Boolean:

var isDisabled = $('textbox').prop('disabled');

Here's the fiddle: http://jsfiddle.net/unhjM/

It looks to me like the background images aren't actually background images...the site has the background images and the quotes in sibling divs with the children of the div containing the images having been assigned position: fixed; The quotes div is also given a transparent background.

wrapper div{
   image wrapper div{
       div for individual image{ <--- Fixed position
          image <--- relative position
       }
   }
   quote wrapper div{
       div for individual quote{
          quote
       }
   }
 }

Why not use the following: (from Draw custom Back button on iPhone Navigation Bar)

// Add left
UINavigationItem *previousItem = [[UINavigationItem alloc] initWithTitle:@"Back title"];
UINavigationItem *currentItem = [[UINavigationItem alloc] initWithTitle:@"Main Title"];
[self.navigationController.navigationBar setItems:[NSArray arrayWithObjects:previousItem, currentItem, nil] animated:YES];

// set the delegate to self
[self.navigationController.navigationBar setDelegate:self];

1. PDO stands for PHP Data Object.
2. PDO_MYSQL is the driver that will implement the interface between the dataobject(database) and the user input (a layer under the user interface called "code behind") accessing your data object, the MySQL database.

The purpose of using this is to implement an additional layer of security between the user interface and the database. By using this layer, data can be normalized before being inserted into your data structure. (Capitals are Capitals, no leading or trailing spaces, all dates at properly formed.)

But there are a few nuances to this which you might not be aware of.

First of all, up until now, you've probably written all your queries in something similar to the URL, and you pass the parameters using the URL itself. Using the PDO, all of this is done under the user interface level. User interface hands off the ball to the PDO which carries it down field and plants it into the database for a 7-point TOUCHDOWN.. he gets seven points, because he got it there and did so much more securely than passing information through the URL.

You can also harden your site to SQL injection by using a data-layer. By using this intermediary layer that is the ONLY 'player' who talks to the database itself, I'm sure you can see how this could be much more secure. Interface to datalayer to database, datalayer to database to datalayer to interface.

And:

By implementing best practices while writing your code you will be much happier with the outcome.

To post your html, javascript,c# and java you should convert special characters to HTML code. as '<' as < and '>' to > and e.t.c..

Add this link Code Converter to iGoogle. This will help you to convert the special characters.

Then add SyntaxHighlighter 3.0.83 new version to customize your code in blogger. But you should know How to configure the syntaxHighlighter in your blogger template.

Quick note for Xamarin developers.

If you would like to call System.gc() in Xamarin.Android apps you should call Java.Lang.JavaSystem.Gc()

Thought I'd add my own solution because nobody yet mentioned this. Instead of designing a UserControl based on Grid, you can target controls contained in grid with a style declaration. Takes care of adding padding/margin to all elements without having to define for each, which is cumbersome and labor-intensive.For instance, if your Grid contains nothing but TextBlocks, you can do this:

<Style TargetType="{x:Type TextBlock}">
    <Setter Property="Margin" Value="10"/>
</Style>

Which is like the equivalent of "cell padding".

Maybe you want set -e:

www.davidpashley.com/articles/writing-robust-shell-scripts.html#id2382181:

This tells bash that it should exit the script if any statement returns a non-true return value. The benefit of using -e is that it prevents errors snowballing into serious issues when they could have been caught earlier. Again, for readability you may want to use set -o errexit.

IFormatProvider provides culture info to the method in question. DateTimeFormatInfo implements IFormatProvider, and allows you to specify the format you want your date/time to be displayed in. Examples can be found on the relevant MSDN pages.

jQuery code snippet to get the dynamic variables stored in the url as parameters and store them as JavaScript variables ready for use with your scripts:

$.urlParam = function(name){
    var results = new RegExp('[\?&]' + name + '=([^&#]*)').exec(window.location.href);
    if (results==null) {
       return null;
    }
    return decodeURI(results[1]) || 0;
}

example.com?param1=name&param2=&id=6

$.urlParam('param1'); // name
$.urlParam('id');        // 6
$.urlParam('param2');   // null

example params with spaces

http://www.jquery4u.com?city=Gold Coast
console.log($.urlParam('city'));  
//output: Gold%20Coast



console.log(decodeURIComponent($.urlParam('city'))); 
//output: Gold Coast

More one example:

Follow:

 qryAux = (from q in qryAux where
            q.OrdSeq == (from pp in Sessao.Query<NameTable>() where pp.FieldPk
            == q.FieldPk select pp.OrdSeq).Max() select q);

Equals:

 select t.*   from nametable t  where t.OrdSeq =
        (select max(t2.OrdSeq) from nametable t2 where t2.FieldPk= t.FieldPk)

If you remove [DataType(DataType.Date)] from your model, the input field in Chrome is rendered as type="datetime" and won't show the datepicker either.

Try using the :input selector, along with a parent selector:

$("#parent-selector :input").attr("disabled", true);

IMO, you should have a look at the Observer Pattern, and this is how most of the listeners work

On newer distros (as of 2016), it seems that PIE is enabled by default so you will need to disable it explicitly when compiling.

Here's a little summary of commands which can be helpful when playing locally with buffer overflow exercises in general:

Disable canary:

gcc vuln.c -o vuln_disable_canary -fno-stack-protector

Disable DEP:

gcc vuln.c -o vuln_disable_dep -z execstack

Disable PIE:

gcc vuln.c -o vuln_disable_pie -no-pie

Disable all of protection mechanisms listed above (warning: for local testing only):

gcc vuln.c -o vuln_disable_all -fno-stack-protector -z execstack -no-pie

For 32-bit machines, you'll need to add the -m32 parameter as well.

content: "";
background-image: url("yourimage.jpg");
background-size: 30px, 30px;

Those two solution require only two nested elements.
First - Relative and absolute positioning if the content is static (manual center).

.black {
    position:relative;
    min-height:500px;
    background:rgba(0,0,0,.5);

}
.message {
    position:absolute;
    margin: 0 auto;
    width: 180px;
    top: 45%; bottom:45%;  left: 0%; right: 0%;
}

https://jsfiddle.net/GlupiJas/5mv3j171/

or for fluid design - for exact content center use below example instead:

.message {
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
}

https://jsfiddle.net/GlupiJas/w3jnjuv0/

You need 'min-height' set in case the content will exceed 50% of window height. You can also manipulate this height with media query for mobile and tablet devices . But only if You play with responsive design.

I guess You could go further and use simple JavaScript/JQuery script to manipulate the min-height or fixed height if there is a need for some reason.

Second - if content is fluid u can also use table and table-cell css properties with vertical alignment and text-align centered:

/*in a wrapper*/  
display:table;   

and

/*in the element inside the wrapper*/
display:table-cell;
vertical-align: middle;
text-align: center;

Works and scale perfectly, often used as responsive web design solution with grid layouts and media query that manipulate the width of the object.

.black {
    display:table;
    height:500px;
    width:100%;
    background:rgba(0,0,0,.5);

}
.message {
    display:table-cell;
    vertical-align: middle;
    text-align: center;
}

https://jsfiddle.net/GlupiJas/4daf2v36/

I prefer table solution for exact content centering, but in some cases relative absolute positioning will do better job especially if we don't want to keep exact proportion of content alignment.

I know the topic is quite old, but such tools are always handy. I've used the resources above and created a version of NtpClient which allows asynchronously to acquire accurate time, instead of event based.

Update: AdoptOpenJDK has changed its name to Adoptium, as part of its move to the Eclipse Foundation.

OpenJDK ? source code
Adoptium/AdoptOpenJDK ? builds

Difference between OpenJDK and AdoptOpenJDK

The first provides source-code, the other provides builds of that source-code.

• OpenJDK is an open-source project providing source-code (not builds) of an implementation of the Java platform as defined by:
  • the Java Specifications
  • Java Specification Request (JSR) documents published by Oracle via the Java Community Process
  • JDK Enhancement Proposal (JEP) documents published by Oracle via the OpenJDK project
• AdoptOpenJDK is an organization founded by some prominent members of the Java community aimed at providing binary builds and installers at no cost for users of Java technology.

Several vendors of Java & OpenJDK

Adoptium of the Eclipse Foundation, formerly known as AdoptOpenJDK, is only one of several vendors distributing implementations of the Java platform. These include:

• Eclipse Foundation (Adoptium/AdoptOpenJDK)
• Azul Systems
• Oracle
• Red Hat / IBM
• BellSoft
• SAP
• Amazon AWS
• … and more

See this flowchart of mine to help guide you in picking a vendor for an implementation of the Java platform. Click/tap to zoom.

Another resource: This comparison matrix by Azul Systems is useful, and seems true and fair to my mind.

Here is a list of considerations and motivations to consider in choosing a vendor and implementation.

Some vendors offer you a choice of JIT technologies.

You can handle loading the excel file content by writing Java code using Apache POI library (https://poi.apache.org/). The library is developed for working with MS office application data including Excel.

I have recently created the application based on the technology that will help you to load Excel files to the Postgres database. The application is available under http://www.abespalov.com/. The application is tested only for Windows, but should work for Linux as well.

The application automatically creates necessary tables with the same columns as in the Excel files and populate the tables with content. You can export several files in parallel. You can skip the step to convert the files into the CSV format. The application handles the xls and xlsx formats.

Overall application stages are :

1. Load the excel file content. Here is the code depending on file extension:

{

fileExtension = FilenameUtils.getExtension(inputSheetFile.getName());
    if (fileExtension.equalsIgnoreCase("xlsx")) {
        workbook = createWorkbook(openOPCPackage(inputSheetFile));
    } else {
        workbook =     
        createWorkbook(openNPOIFSFileSystemPackage(inputSheetFile));
    }

sheet = workbook.getSheetAt(0);

}

2. Establish Postgres JDBC connection
3. Create a Postgres table
4. Iterate over the sheet and inset rows into the table. Here is a piece of Java code :

{

Iterator<Row> rowIterator = InitInputFilesImpl.sheet.rowIterator();

//skip a header
if (rowIterator.hasNext()) {
    rowIterator.next();
}
while (rowIterator.hasNext()) {
    Row row = (Row) rowIterator.next();
    // inserting rows
}  

}

Here you can find all Java code for the application created for exporting excel to Postgres (https://github.com/palych-piter/Excel2DB).

A cherry-pick is basically a commit, so if you want to undo it, you just undo the commit.

when I have other local changes

Stash your current changes so you can reapply them after resetting the commit.

$ git stash
$ git reset --hard HEAD^
$ git stash pop  # or `git stash apply`, if you want to keep the changeset in the stash

when I have no other local changes

$ git reset --hard HEAD^

There is one fatal flaw in this otherwise great and helpful test: As memset is the first instruction, there seems to be some "memory overhead" or so which makes it extremely slow. Moving the timing of memset to second place and something else to first place or simply timing memset twice makes memset the fastest with all compile switches!!!

We can use ng-src but when ng-src's value became null, '' or undefined, ng-src will not work. So just use ng-if for this case:

http://jsfiddle.net/Hx7B9/299/

<div ng-app>
    <div ng-controller="AppCtrl"> 
        <a href='#'><img ng-src="{{link}}" ng-if="!!link"/></a>
        <button ng-click="changeLink()">Change Image</button>
    </div>
</div>

char* str=NULL;
int len = asprintf(&str, "%g", float_var);
if (len == -1)
  fprintf(stderr, "Error converting float: %m\n");
else
  printf("float is %s\n", str);
free(str);

It's a tricky implicit array equality checking but can handle the job right after coherence arrays to string.

var a1 = [1, 2, 3];
var a2 = [1, 2, 3];
var isEqual = a1 <= a2 && a1 >= a2; // true

I don't know why some of these answers are ridiculously long or complex. Here's one using the DateTime Class. Kind of similar to radzserg's answer. This will only display the units necessary, and negative times will have the 'ago' suffix...

function calctime($seconds = 0) {

    $datetime1 = date_create("@0");
    $datetime2 = date_create("@$seconds");
    $interval = date_diff($datetime1, $datetime2);

    if ( $interval->y >= 1 ) $thetime[] = pluralize( $interval->y, 'year' );
    if ( $interval->m >= 1 ) $thetime[] = pluralize( $interval->m, 'month' );
    if ( $interval->d >= 1 ) $thetime[] = pluralize( $interval->d, 'day' );
    if ( $interval->h >= 1 ) $thetime[] = pluralize( $interval->h, 'hour' );
    if ( $interval->i >= 1 ) $thetime[] = pluralize( $interval->i, 'minute' );
    if ( $interval->s >= 1 ) $thetime[] = pluralize( $interval->s, 'second' );

    return isset($thetime) ? implode(' ', $thetime) . ($interval->invert ? ' ago' : '') : NULL;
}

function pluralize($count, $text) {
    return $count . ($count == 1 ? " $text" : " ${text}s");
}

// Examples:
//    -86400 = 1 day ago
//     12345 = 3 hours 25 minutes 45 seconds
// 987654321 = 31 years 3 months 18 days 4 hours 25 minutes 21 seconds

EDIT: If you want to condense the above example down to use less variables / space (at the expense of legibility), here is an alternate version that does the same thing:

function calctime($seconds = 0) {
    $interval = date_diff(date_create("@0"),date_create("@$seconds"));

    foreach (array('y'=>'year','m'=>'month','d'=>'day','h'=>'hour','i'=>'minute','s'=>'second') as $format=>$desc) {
        if ($interval->$format >= 1) $thetime[] = $interval->$format . ($interval->$format == 1 ? " $desc" : " {$desc}s");
    }

    return isset($thetime) ? implode(' ', $thetime) . ($interval->invert ? ' ago' : '') : NULL;
}

If for some reason it's still not working. First option for Laravel The second option for any application

FIRST OPTION:

1. As in the example above, we create middleware

    php artisan make:middleware Cors
   

2. Add the following code to app/Http/Middleware/Cors.php:

    public function handle($request, Closure $next) 
    {
        return $next($request)
            ->header('Access-Control-Allow-Origin', '*')
            ->header('Access-Control-Allow-Methods', 'GET, POST, PUT, PATCH, DELETE, OPTIONS')
            ->header('Access-Control-Allow-Headers', 'Authorization,Accept,Origin,DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Content-Range,Range'); 
    }
   

Look closely, the amount of data in the header ->header('Access-Control-Allow-Headers',

3. Step three, add middleware to $routeMiddleware array in app/Http/Kernel.php

    protected $routeMiddleware = [
        ....
        'cors' => \App\Http\Middleware\Cors::class,
    ];
   

SECOND OPTION:

1. Open the nginx.conf settings for your domain.

    sudo nano /etc/nginx/sites-enabled/your-domain.conf
   

2. Inside the server settings server { listen 80; .... } please add the following code:

    add_header 'Access-Control-Allow-Origin' '*';
    add_header 'Access-Control-Allow-Credentials' 'true';
    add_header 'Access-Control-Allow-Headers' 'Authorization,Accept,Origin,DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Content-Range,Range';
    add_header 'Access-Control-Allow-Methods' 'GET,POST,OPTIONS,PUT,DELETE,PATCH';
   

If your table t1 and it's backup t2 have many columns, here's a compact way to do it.

In addition, my related problem was that only some of the columns were modified and many rows had no edits to these columns, so I wanted to leave those alone - basically restore a subset of columns from a backup of the entire table. If you want to just restore all rows, skip the where clause.

Of course the simpler way would be to delete and insert as select, but in my case I needed a solution with just updates.

The trick is that when you do select * from a pair of tables with duplicate column names, the 2nd one will get named _1. So here's what I came up with:

  update (
    select * from t1 join t2 on t2.id = t1.id
    where id in (
      select id from (
        select id, col1, col2, ... from t2
        minus select id, col1, col2, ... from t1
      )
    )
  ) set col1=col1_1, col2=col2_1, ...

Everything you write in your own stylesheet is overwriting the user agent styles - that's the point of writing your own stylesheet.

I noticed the issue the moment I updated Chrome on os x to the latest stable release (9.0.597.94) so this is a Chrome bug and hopefully will be fixed.

I'm tempted not to even attempt to work around this and just wait for the fix. It'll just mean more work taking it out.

Found a step-by-step way to achieve this (for 1 font):
(as of Sep-9 2013)

1. Choose your font at http://www.google.com/fonts
2. Add the desired one to your collection using "Add to collection" blue button
3. Click the "See all styles" button near "Remove from collection" button and make sure that you have selected other styles you may also need such as 'bold'...
4. Click the 'Use' tab button on bottom right of the page
5. Click the download button on top with a down arrow image
6. Click on "zip file" on the the popup message that appears
7. Click "Close" button on the popup
8. Slowly scroll the page until you see the 3 tabs "Standrd|@import|Javascript"
9. Click "@import" tab
10. Select and copy the url between 'url(' and ')'
11. Copy it on address bar in a new tab and go there
12. Do "File > Save page as..." and name it "desiredfontname.css" (replace accordingly)
13. Decompress the fonts .zip file you downloaded (.ttf should be extracted)
14. Go to "http://ttf2woff.com/" and convert any .ttf extracted from zip to .woff
15. Edit desiredfontname.css and replace any url within it [between 'url(' and ')'] with the corresponding converted .woff file you got on ttf2woff.com; path you write should be according to your server doc_root
16. Save the file and move it at its final place and write the corresponding <link/> CSS tag to import these in your HTML page
17. From now, refer to this font by its font-family name in your styles

That's it. Cause I had the same problem and the solution on top did not work for me.

In eclipse format xml:

For tab:

<setting id="org.eclipse.jdt.core.formatter.tabulation.char" value="tab"/>

For space:

The "reference" Java implementation by Sean Leary is here on github. Make sure to have the latest version - different libraries pull in versions buggy old versions from 2009.

Java EE 7 has a JSON API in javax.json, see the Javadoc. From what I can tell, it doesn't have a simple method to marshall any object to JSON, you need to construct a JsonObject or a JsonArray.

import javax.json.*;

JsonObject value = Json.createObjectBuilder()
 .add("firstName", "John")
 .add("lastName", "Smith")
 .add("age", 25)
 .add("address", Json.createObjectBuilder()
     .add("streetAddress", "21 2nd Street")
     .add("city", "New York")
     .add("state", "NY")
     .add("postalCode", "10021"))
 .add("phoneNumber", Json.createArrayBuilder()
     .add(Json.createObjectBuilder()
         .add("type", "home")
         .add("number", "212 555-1234"))
     .add(Json.createObjectBuilder()
         .add("type", "fax")
         .add("number", "646 555-4567")))
 .build();

JsonWriter jsonWriter = Json.createWriter(...);
jsonWriter.writeObject(value);
jsonWriter.close();

But I assume the other libraries like GSON will have adapters to create objects implementing those interfaces.

Is it possible that you use docker on OS X via boot2docker or something similar.

I've made the same experience - the command is correct but nothing (sensible) is mounted in the container, anyway.

As it turns out - it's already explained in the docker documentation. When you type docker run -v /var/logs/on/host:/var/logs/in/container ... then /var/logs/on/host is actually mapped from the boot2docker VM-image, not your Mac.

You'll have to pipe the shared folder through your VM to your actual host (the Mac in my case).

I am not sure there is a way to do it automatically without javascript.

What you need is something which runs on the browser side to submit your form back to the server when they user makes a selection - hence, javascript.

Also, ensure you have an alternate means (i.e. a submit button) for those who have javascript turned off.

A good example: Combo-Box Viewer

I had even a more sophisticated combo-box yesterday, with this dhtmlxCombo , using ajax to retrieve pertinent values amongst large quantity of data.

Use ProcessBuilder.inheritIO, it sets the source and destination for subprocess standard I/O to be the same as those of the current Java process.

Process p = new ProcessBuilder().inheritIO().command("command1").start();

If Java 7 is not an option

public static void main(String[] args) throws Exception {
    Process p = Runtime.getRuntime().exec("cmd /c dir");
    inheritIO(p.getInputStream(), System.out);
    inheritIO(p.getErrorStream(), System.err);

}

private static void inheritIO(final InputStream src, final PrintStream dest) {
    new Thread(new Runnable() {
        public void run() {
            Scanner sc = new Scanner(src);
            while (sc.hasNextLine()) {
                dest.println(sc.nextLine());
            }
        }
    }).start();
}

Threads will die automatically when subprocess finishes, because src will EOF.

if you have ID or any specific field in your item, you can use filter(). its act like Where().

<a class="btn" ng-click="remove(item)">Delete</a>

in controller:

$scope.remove = function(item) { 
  $scope.bdays = $scope.bdays.filter(function (element) {
                    return element.ID!=item.ID
                });
}

You need to add a Serializable attribute to the class which you want to serialize.

[Serializable]
public class OrgPermission

Facebook does not allow to share plain text data with Intent.EXTRA_TEXT but You can share text+link with facebook messanger using this, this works fine for me

            Intent sendIntent = new Intent();
            sendIntent.setAction(Intent.ACTION_SEND);
            sendIntent.putExtra(Intent.EXTRA_TEXT, text+url link);
            sendIntent.setType("text/plain");
            sendIntent.setPackage("com.facebook.orca");
            startActivity(sendIntent);

Using modern --inspect with node the console.log is captured and relayed to the browser.

node --inspect myApp.js

or to capture early logging --inspect-brk can be used to stop the program on the first line of the first module...

node --inspect-brk myApp.js

You can try this if it suits you...

Put a textarea inside your td and disable it with background color white and define its number of rows.

<table style="width: 100%;">
  <tr>
    <td>
        <textarea rows="4" style="background-color:white;border: none;" disabled>      Looooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooong word
      </textarea>
    </td>
    <td><span style="display: inline;">Short word</span></td>
  </tr>
</table>

Thanks for enlightening us Cypawer.

I also tried this app https://play.google.com/store/apps/details?id=com.oneguyinabasement.leapwifi

and it worked flawlessly.

Why dont use something like:

$.isNumeric($(input).val())

Is jquery tested, and the most common case are checked

@webdeb's answer didn't work for me, I hit an unexpected token error when compiling ES6 with Babel, doing named default exports.

This worked for me, however:

// Foo.js
export default Foo
...

// bundle.js
export { default as Foo } from './Foo'
export { default as Bar } from './Bar'
...

// and import somewhere..
import { Foo, Bar } from './bundle'

Thank you for everyone's assistance and pushing to get rid of the eval statement. Variables needed to be in brackets, not dot notation. This works and is clean, proper code.

Each of these are variables: appChoice, underI, underObstr.

if(typeof tData.tonicdata[appChoice][underI][underObstr] !== "undefined"){
    //enter code here
}

tl;dr: baz() { this.foo(); this.bar() }

In ES2015 this construct:

var obj = {
    foo() { console.log('foo') }
}

is equal to this ES5 code:

var obj = {
    foo : function foo() { console.log('foo') }
}

exports.default = {} is like creating an object, your default export translates to ES5 code like this:

exports['default'] = {
    foo: function foo() {
        console.log('foo');
    },
    bar: function bar() {
        console.log('bar');
    },
    baz: function baz() {
        foo();bar();
    }
};

now it's kind of obvious (I hope) that baz tries to call foo and bar defined somewhere in the outer scope, which are undefined. But this.foo and this.bar will resolve to the keys defined in exports['default'] object. So the default export referencing its own methods shold look like this:

export default {
    foo() { console.log('foo') }, 
    bar() { console.log('bar') },
    baz() { this.foo(); this.bar() }
}

See babel repl transpiled code.

For those looking for a command-line version, Microsoft released mssql-scripter to do this:

$ pip install mssql-scripter

# Generate DDL scripts for all database objects and DML scripts (INSERT statements)
# for all tables in the Adventureworks database and save the script files in
# the current directory
$ mssql-scripter -S localhost -d AdventureWorks -U sa --schema-and-data \
                 -f './' --file-per-object

dbatools.io is a much more active project based on PowerShell, which provides the Get-DbaDbTable and Export-DbaDbTableData cmdlets to achieve this:

PS C:\> Get-DbaDbTable -SqlInstance sql2016 -Database MyDatabase \
           -Table 'dbo.Table1', 'dbo.Table2' | 
        Export-DbaDbTableData -Path C:\temp\export.sql

You can use a GoTo:

Do

    '... do stuff your loop will be doing

    ' skip to the end of the loop if necessary:
    If <condition-to-go-to-next-iteration> Then GoTo ContinueLoop 

    '... do other stuff if the condition is not met

ContinueLoop:
Loop

You could also type 'conda list' in a command line. This will print out the installed modules with the version numbers. The path within your file structure will be printed at the top of this list.

As per the documentation: FROM (Transact-SQL):

<join_type> ::= 
    [ { INNER | { { LEFT | RIGHT | FULL } [ OUTER ] } } [ <join_hint> ] ]
    JOIN

The keyword OUTER is marked as optional (enclosed in square brackets). In this specific case, whether you specify OUTER or not makes no difference. Note that while the other elements of the join clause is also marked as optional, leaving them out will make a difference.

For instance, the entire type-part of the JOIN clause is optional, in which case the default is INNER if you just specify JOIN. In other words, this is legal:

SELECT *
FROM A JOIN B ON A.X = B.Y

Here's a list of equivalent syntaxes:

A LEFT JOIN B            A LEFT OUTER JOIN B
A RIGHT JOIN B           A RIGHT OUTER JOIN B
A FULL JOIN B            A FULL OUTER JOIN B
A INNER JOIN B           A JOIN B

Also take a look at the answer I left on this other SO question: SQL left join vs multiple tables on FROM line?.

There's a lot of great - complex - answers here. In my particular case i found a clean and simple fix for the logout. I have yet to test in Edge. On my page that I have logged in to, I have placed a logout link similar to this:

<a href="https://MyDomainHere.net/logout.html">logout</a>

And in the head of that logout.html page (which is also protected by the .htaccess) I have a page refresh similar to this:

<meta http-equiv="Refresh" content="0; url=https://logout:[email protected]/" />

Where you would leave the words "logout" in place to clear the username and password cached for the site.

I will admit that if multiple pages needed to be able to be directly logged in to from the beginning, each of those points of entry would need their own corresponding logout.html page. Otherwise you could centralize the logout by introducing an additional gatekeeper step into the process before the actual login prompt, requiring entry of a phrase to reach a destination of login.

Let us see the difference between the two HTTP authentication using Wireshark (Tool to analyse packets sent or received) .

1. Http Basic Authentication

As soon as the client types in the correct username:password,as requested by the Web-server, the Web-Server checks in the Database if the credentials are correct and gives the access to the resource .

Here is how the packets are sent and received :

In the first packet the Client fill the credentials using the POST method at the resource - lab/webapp/basicauth .In return the server replies back with http response code 200 ok ,i.e, the username:password were correct .

Now , In the Authorization header it shows that it is Basic Authorization followed by some random string .This String is the encoded (Base64) version of the credentials admin:aadd (including colon ) .

2 . Http Digest Authentication(rfc 2069)

So far we have seen that the Basic Authentication sends username:password in plaintext over the network .But the Digest Auth sends a HASH of the Password using Hash algorithm.

Here are packets showing the requests made by the client and response from the server .

As soon as the client types the credentials requested by the server , the Password is converted to a response using an algorithm and then is sent to the server , If the server Database has same response as given by the client the server gives the access to the resource , otherwise a 401 error .

In the above Authorization , the response string is calculated using the values of Username,Realm,Password,http-method,URI and Nonce as shown in the image :

(colons are included)

Hence , we can see that the Digest Authentication is more Secure as it involve Hashing (MD5 encryption) , So the packet sniffer tools cannot sniff the Password although in Basic Auth the exact Password was shown on Wireshark.

For Cross-Browser Compatibility :

Example Goes Below :

<html><body class="entire-webpage"></body></html>



.entire-webpage{
        zoom: 2;
        -moz-transform: scale(2);/* Firefox Property */
        -moz-transform-origin: 0 0;
        -o-transform: scale(2);/* Opera Property */
        -o-transform-origin: 0 0;
        -webkit-transform: scale(2);/* Safari Property */
        -webkit-transform-origin: 0 0;
        transform: scale(2); /* Standard Property */
        transform-origin: 0 0;  /* Standard Property */
    }

You can have awk do it all without using cut:

awk '{print substr($7,index($7,"=")+1)}' inputfile

You could use split() instead of substr(index()).

I think you should avoid camel caps. The norm is to use lower case letters. I would also avoid underscores and use dashes instead

So your URL should look like this (ignoring the design issues as you requested :-))

api.service.com/hello-world/user-id/x

The RemoveAll() methods accept a Predicate<T> delegate (until here nothing new). A predicate points to a method that simply returns true or false. Of course, the RemoveAll will remove from the collection all the T instances that return True with the predicate applied.

C# 3.0 lets the developer use several methods to pass a predicate to the RemoveAll method (and not only this one…). You can use:

Lambda expressions

vehicles.RemoveAll(vehicle => vehicle.EnquiryID == 123);

Anonymous methods

vehicles.RemoveAll(delegate(Vehicle v) {
  return v.EnquiryID == 123;
});

Normal methods

vehicles.RemoveAll(VehicleCustomPredicate);
private static bool
VehicleCustomPredicate (Vehicle v) {
    return v.EnquiryID == 123; 
}

First to answer your question, you set a variable to true or false by assigning True or False to it:

myFirstVar = True
myOtherVar = False

If you have a condition that is basically like this though:

if <condition>:
    var = True
else:
    var = False

then it is much easier to simply assign the result of the condition directly:

var = <condition>

In your case:

match_var = a == b

If you are using XAMPP as your server, you'll find a logs directory as a child of the XAMPP directory. If you have not tried XAMPP, which runs on any system (Windows, Mac OS & Linux) find more here: http://www.apachefriends.org/en/xampp.html

DefaultThreadCurrentCulture and DefaultThreadCurrentUICulture are present in Framework 4.0 too, but they are Private. Using Reflection you can easily set them. This will affect all threads where CurrentCulture is not explicitly set (running threads too).

Public Sub SetDefaultThreadCurrentCulture(paCulture As CultureInfo)
    Thread.CurrentThread.CurrentCulture.GetType().GetProperty("DefaultThreadCurrentCulture").SetValue(Thread.CurrentThread.CurrentCulture, paCulture, Nothing)
    Thread.CurrentThread.CurrentCulture.GetType().GetProperty("DefaultThreadCurrentUICulture").SetValue(Thread.CurrentThread.CurrentCulture, paCulture, Nothing)
End Sub

You can try defining a constant in index.php and add something like

if (!defined("YOUR_CONSTANT")) die('No direct access');

to the beginning of the other files.

OR, you can use mod_rewrite and redirect requests to index.php, editing .htaccess like this:

RewriteEngine on
RewriteCond $1 !^(index\.php)
RewriteRule ^(.*)$ /index.php/$1 [L,R=301]

Then you should be able to analyze all incoming requests in the index.php and take according actions.

If you want to leave out all *.jpg, *.gif, *.css and *.png files, for example, then you should edit second line like this:

RewriteCond $1 !^(index\.php|*\.jpg|*\.gif|*\.css|*\.png)

On strings and memory allocation:

A string in C is just a sequence of chars, so you can use char * or a char array wherever you want to use a string data type:

typedef struct     {
  int number;
  char *name;
  char *address;
  char *birthdate;
  char gender;
} patient;

Then you need to allocate memory for the structure itself, and for each of the strings:

patient *createPatient(int number, char *name, 
  char *addr, char *bd, char sex) {

  // Allocate memory for the pointers themselves and other elements
  // in the struct.
  patient *p = malloc(sizeof(struct patient));

  p->number = number; // Scalars (int, char, etc) can simply be copied

  // Must allocate memory for contents of pointers.  Here, strdup()
  // creates a new copy of name.  Another option:
  // p->name = malloc(strlen(name)+1);
  // strcpy(p->name, name);
  p->name = strdup(name);
  p->address = strdup(addr);
  p->birthdate = strdup(bd);
  p->gender = sex;
  return p;
}

If you'll only need a few patients, you can avoid the memory management at the expense of allocating more memory than you really need:

typedef struct     {
  int number;
  char name[50];       // Declaring an array will allocate the specified
  char address[200];   // amount of memory when the struct is created,
  char birthdate[50];  // but pre-determines the max length and may
  char gender;         // allocate more than you need.
} patient;

On linked lists:

In general, the purpose of a linked list is to prove quick access to an ordered collection of elements. If your llist contains an element called num (which presumably contains the patient number), you need an additional data structure to hold the actual patients themselves, and you'll need to look up the patient number every time.

Instead, if you declare

typedef struct llist
{
  patient *p;
  struct llist *next;
} list;

then each element contains a direct pointer to a patient structure, and you can access the data like this:

patient *getPatient(list *patients, int num) {
  list *l = patients;
  while (l != NULL) {
    if (l->p->num == num) {
      return l->p;
    }
    l = l->next;
  }
  return NULL;
}

Elements that are not being rendered (be it through visibility: hidden, display: none, opacity: 0.0, whatever) will not indicate focus. The browser will not draw a focus border around nothing.

If you want the text to be focusable, that's completely doable. You can wrap the whole thing in an element that can receive focus (for example, a hyperlink), or allow another tag to have focus using the tabindex property:

<label tabindex="0" class="checkbox">
  <input type="checkbox" value="valueofcheckbox" style="display:none" checked="checked" />Option Text
</label>

Fiddle

In this case, the <label> tag above is actually receiving focus and everything within it will have a focus border when it's in focus.

I do question what your goal is. If you're using a hidden checkbox to internally track some sort of state, you might be better off using a <input type="hidden" /> tag instead.

please import requestoptions from angular cors

    import {RequestOptions, Request, Headers } from '@angular/http';

and add request options in your code like given below

    let requestOptions = new RequestOptions({ headers:null, withCredentials: 
    true });

send request option in your api request

code snippet below-

     let requestOptions = new RequestOptions({ headers:null, 
     withCredentials: true });
     return this.http.get(this.config.baseUrl + 
     this.config.getDropDownListForProject, requestOptions)
     .map(res => 
     {
      if(res != null)
      { 
        return res.json();
        //return true;
      }
    })
  .catch(this.handleError);
   }  

and add CORS in your backend PHP code where all api request will land first.

try this and let me know if it is working or not i had a same issue i was adding CORS from angular5 that was not working then i added CORS to backend and it worked for me

Actually this will give you repeated indices np.random.random_integers(0, len(df), N) where N is a large number.

Check out this snippet:

Private Sub openDialog()
    Dim fd As Office.FileDialog

    Set fd = Application.FileDialog(msoFileDialogFilePicker)

   With fd

      .AllowMultiSelect = False

      ' Set the title of the dialog box.
      .Title = "Please select the file."

      ' Clear out the current filters, and add our own.
      .Filters.Clear
      .Filters.Add "Excel 2003", "*.xls"
      .Filters.Add "All Files", "*.*"

      ' Show the dialog box. If the .Show method returns True, the
      ' user picked at least one file. If the .Show method returns
      ' False, the user clicked Cancel.
      If .Show = True Then
        txtFileName = .SelectedItems(1) 'replace txtFileName with your textbox

      End If
   End With
End Sub

I think this is what you are asking for.

For numerous reasons, No.

Why is explained in this MSDN post.

First, from a performance perspective the pointers get larger, so data structures get larger, and the processor cache stays the same size. That basically results in a raw speed hit (your mileage may vary). So you start in a hole and you have to dig yourself out of that hole by using the extra memory above 4G to your advantage. In Visual Studio this can happen in some large solutions but I think a preferable thing to do is to just use less memory in the first place. Many of VS’s algorithms are amenable to this. Here’s an old article that discusses the performance issues at some length: https://docs.microsoft.com/archive/blogs/joshwil/should-i-choose-to-take-advantage-of-64-bit

Secondly, from a cost perspective, probably the shortest path to porting Visual Studio to 64 bit is to port most of it to managed code incrementally and then port the rest. The cost of a full port of that much native code is going to be quite high and of course all known extensions would break and we’d basically have to create a 64 bit ecosystem pretty much like you do for drivers. Ouch.

This worked for me:

<button #loginButton ...

and inside the controller:

You can use the following in Firebase (FCM) to get the token:

FirebaseInstanceId.getInstance().getToken();

Try something like:

SELECT       `column`
    FROM     `your_table`
    GROUP BY `column`
    ORDER BY COUNT(*) DESC
    LIMIT    1;

Use iloc to access by position (rather than label):

In [11]: df = pd.DataFrame([[1, 2], [3, 4]], ['a', 'b'], ['A', 'B'])

In [12]: df
Out[12]: 
   A  B
a  1  2
b  3  4

In [13]: df.iloc[0]  # first row in a DataFrame
Out[13]: 
A    1
B    2
Name: a, dtype: int64

In [14]: df['A'].iloc[0]  # first item in a Series (Column)
Out[14]: 1

In my case i created below queries but in the first query if id 1 is already exists and age is already there, after that if you create first query without age than the value of age will be none

REPLACE into table SET `id` = 1, `name` = 'A', `age` = 19

for avoiding above issue create query like below

INSERT INTO table SET `id` = '1', `name` = 'A', `age` = 19 ON DUPLICATE KEY UPDATE `id` = "1", `name` = "A",`age` = 19

may it will help you ...

The first thing you need to study is the java.util.Set API.

Here's a small example of how to use its methods:

    Set<Integer> numbers = new TreeSet<Integer>();

    numbers.add(2);
    numbers.add(5);

    System.out.println(numbers); // "[2, 5]"
    System.out.println(numbers.contains(7)); // "false"

    System.out.println(numbers.add(5)); // "false"
    System.out.println(numbers.size()); // "2"

    int sum = 0;
    for (int n : numbers) {
        sum += n;
    }
    System.out.println("Sum = " + sum); // "Sum = 7"

    numbers.addAll(Arrays.asList(1,2,3,4,5));
    System.out.println(numbers); // "[1, 2, 3, 4, 5]"

    numbers.removeAll(Arrays.asList(4,5,6,7));
    System.out.println(numbers); // "[1, 2, 3]"

    numbers.retainAll(Arrays.asList(2,3,4,5));
    System.out.println(numbers); // "[2, 3]"

Once you're familiar with the API, you can use it to contain more interesting objects. If you haven't familiarized yourself with the equals and hashCode contract, already, now is a good time to start.

In a nutshell:

• @Override both or none; never just one. (very important, because it must satisfied property: a.equals(b) == true --> a.hashCode() == b.hashCode()
  • Be careful with writing boolean equals(Thing other) instead; this is not a proper @Override.
• For non-null references x, y, z, equals must be:
  • reflexive: x.equals(x).
  • symmetric: x.equals(y) if and only if y.equals(x)
  • transitive: if x.equals(y) && y.equals(z), then x.equals(z)
  • consistent: x.equals(y) must not change unless the objects have mutated
  • x.equals(null) == false
• The general contract for hashCode is:
  • consistent: return the same number unless mutation happened
  • consistent with equals: if x.equals(y), then x.hashCode() == y.hashCode()
    • strictly speaking, object inequality does not require hash code inequality
    • but hash code inequality necessarily requires object inequality
• What counts as mutation should be consistent between equals and hashCode.

Next, you may want to impose an ordering of your objects. You can do this by making your type implements Comparable, or by providing a separate Comparator.

Having either makes it easy to sort your objects (Arrays.sort, Collections.sort(List)). It also allows you to use SortedSet, such as TreeSet.

The General Syntax of operator overloading in C++

You cannot change the meaning of operators for built-in types in C++, operators can only be overloaded for user-defined types¹. That is, at least one of the operands has to be of a user-defined type. As with other overloaded functions, operators can be overloaded for a certain set of parameters only once.

Not all operators can be overloaded in C++. Among the operators that cannot be overloaded are: . :: sizeof typeid .* and the only ternary operator in C++, ?:

Among the operators that can be overloaded in C++ are these:

• arithmetic operators: + - * / % and += -= *= /= %= (all binary infix); + - (unary prefix); ++ -- (unary prefix and postfix)
• bit manipulation: & | ^ << >> and &= |= ^= <<= >>= (all binary infix); ~ (unary prefix)
• boolean algebra: == != < > <= >= || && (all binary infix); ! (unary prefix)
• memory management: new new[] delete delete[]
• implicit conversion operators
• miscellany: = [] -> ->* , (all binary infix); * & (all unary prefix) () (function call, n-ary infix)

However, the fact that you can overload all of these does not mean you should do so. See the basic rules of operator overloading.

In C++, operators are overloaded in the form of functions with special names. As with other functions, overloaded operators can generally be implemented either as a member function of their left operand's type or as non-member functions. Whether you are free to choose or bound to use either one depends on several criteria.² A unary operator @³, applied to an object x, is invoked either as operator@(x) or as x.operator@(). A binary infix operator @, applied to the objects x and y, is called either as operator@(x,y) or as x.operator@(y).⁴

Operators that are implemented as non-member functions are sometimes friend of their operand’s type.

¹ _{The term “user-defined” might be slightly misleading. C++ makes the distinction between built-in types and user-defined types. To the former belong for example int, char, and double; to the latter belong all struct, class, union, and enum types, including those from the standard library, even though they are not, as such, defined by users.}

² _{This is covered in a later part of this FAQ.}

³ _{The @ is not a valid operator in C++ which is why I use it as a placeholder.}

⁴ _{The only ternary operator in C++ cannot be overloaded and the only n-ary operator must always be implemented as a member function.}

I would suggest to use jquery for this type of requirement . Give this a try

<div id="commentList"></div>
<div id="addCommentContainer">
    <p>Add a Comment</p> <br/> <br/>
    <form id="addCommentForm" method="post" action="">
        <div>
            Your Name <br/>
            <input type="text" name="name" id="name" />


            <br/> <br/>
            Comment Body <br/>
            <textarea name="body" id="body" cols="20" rows="5"></textarea>

            <input type="submit" id="submit" value="Submit" />
        </div>
    </form>
</div>?

$(document).ready(function(){
    /* The following code is executed once the DOM is loaded */

    /* This flag will prevent multiple comment submits: */
    var working = false;
    $("#submit").click(function(){
    $.ajax({
         type: 'POST',
         url: "mysubmitpage.php",
         data: $('#addCommentForm').serialize(), 
         success: function(response) {
            alert("Submitted comment"); 
             $("#commentList").append("Name:" + $("#name").val() + "<br/>comment:" + $("#body").val());
         },
        error: function() {
             //$("#commentList").append($("#name").val() + "<br/>" + $("#body").val());
            alert("There was an error submitting comment");
        }
     });
});
});?

Something like this?

foreach ($Offer as $key => $value) { 
  $offerArray[$key] = $value[4];
}

Amazon Linux: fixing GCC issue

Since this comes up as the first result on Google, I just wanted to document my experience with Amazon Linux. Installing gcc-c++.noarch fixed the problem:

sudo yum install gcc-c++.noarch

Some people also reported this alternative as a solution:

sudo yum install gcc72-c++

This may be a bit off-topic, since you are asking about static file serving via Node.js specifically (where fs.createReadStream('./image/demo.jpg').pipe(res) is actually a good idea), but in production you may want to have your Node app handle tasks, that cannot be tackled otherwise, and off-load static serving to e.g Nginx.

This means less coding inside your app, and better efficiency since reverse proxies are by design ideal for this.

Also i got this error if i had the comment in tn top level of template among with the actual root element.

Get all file item and filter them by suffix and then use PowerShell Excel VBA object to save the excel files to csv files.

$excelApp = New-Object -ComObject Excel.Application 
$excelApp.DisplayAlerts = $false 

$ExcelFiles | ForEach-Object { 
    $workbook = $excelApp.Workbooks.Open($_.FullName) 
    $csvFilePath = $_.FullName -replace "\.xlsx$", ".csv" 
    $workbook.SaveAs($csvFilePath, [Microsoft.Office.Interop.Excel.XlFileFormat]::xlCSV) 
    $workbook.Close() 
}

The split method will create an array. So you need to access the third element in your case..

(arrays are 0-indexed) You need to access result[2] to get the url

var result = $(row).text().split('|');
alert( result[2] );

You do not give us enough information to know what row is, exactly.. So depending on how you acquire the variable row you might need to do one of the following.

• if row is a string then row.split('|');
• if it is a DOM element then $(row).text().split('|');
• if it is an input element then $(row).val().split('|');

Should be probably changed to

firstName = firstName.trim().replaceAll("\\.", "");

There is a generic solution:

Lets say you have a controller named Admin where you put content for authorized users.

Then, you can override the Initialize or OnAuthorization methods of Admin controller and write redirect to login page logic on session timeout in these methods as described:

protected override void OnAuthorization(System.Web.Mvc.AuthorizationContext filterContext)
    {
        //lets say you set session value to a positive integer
        AdminLoginType = Convert.ToInt32(filterContext.HttpContext.Session["AdminLoginType"]);
        if (AdminLoginType == 0)
        {
            filterContext.HttpContext.Response.Redirect("~/login");
        }

        base.OnAuthorization(filterContext);
    }

You can also left pad with zeros. For example if you want number to have 9 characters length, left padded with zeros use:

print('{:09.3f}'.format(number))

Thus, if number = 4.656, the output is: 00004.656

For your example the output will look like this:

numbers  = [23.2300, 0.1233, 1.0000, 4.2230, 9887.2000]
for x in numbers: 
    print('{:010.4f}'.format(x))

prints:

00023.2300
00000.1233
00001.0000
00004.2230
09887.2000

One example where this may be useful is when you want to properly list filenames in alphabetical order. I noticed in some linux systems, the number is: 1,10,11,..2,20,21,...

Thus if you want to enforce the necessary numeric order in filenames, you need to left pad with the appropriate number of zeros.

get the latest version information from:

https://mvnrepository.com/artifact/org.apache.maven.plugins/maven-compiler-plugin

click on the latest version (or the one you'd like to use) and you'll see the the dependency info (as of 2019-05 it's 3.8.1):

<!-- https://mvnrepository.com/artifact/org.apache.maven.plugins/maven-compiler-plugin -->
<dependency>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <version>3.8.1</version>
</dependency>

you might want to use the version tag and the comment for your plugin tag.

<!-- https://mvnrepository.com/artifact/org.apache.maven.plugins/maven-compiler-plugin -->
<plugin>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.8.1</version>
    <configuration>
        <source />

if you like you can modify your pom to have the version information in the properties tag as outlined in another answer.

The quickest (and most flexible) way is to use np.where, which chooses between two arrays according to a mask(array of true and false values):

import numpy as np
a = np.random.randint(0, 5, size=(5, 4))
b = np.where(a<3,0,1)
print('a:',a)
print()
print('b:',b)

which will produce:

a: [[1 4 0 1]
 [1 3 2 4]
 [1 0 2 1]
 [3 1 0 0]
 [1 4 0 1]]

b: [[0 1 0 0]
 [0 1 0 1]
 [0 0 0 0]
 [1 0 0 0]
 [0 1 0 0]]

Just use standard go flags with iniflags.

Standard go flags have the following benefits:

• Idiomatic.
• Easy to use. Flags can be easily added and scattered across arbitrary packages your project uses.
• Flags have out-of-the-box support for default values and description.
• Flags provide standard 'help' output with default values and description.

The only drawback standard go flags have - is management problems when the number of flags used in your app becomes too large.

Iniflags elegantly solves this problem: just modify two lines in your main package and it magically gains support for reading flag values from ini file. Flags from ini files can be overriden by passing new values in command-line.

I might be very late but encoutered this problem sometime before and saw this link. Thanks . Please check this shall work.

I'm using thread safe static class. Main idea is to queue the message on list and then save to log file each period of time, or each counter limit.

Important: You should force save file ( DirectLog.SaveToFile(); ) when you exit the program. (in case that there are still some items on the list)

The use is very simple: DirectLog.Log("MyLogMessage", 5);

This is my code:

using System;
using System.IO;
using System.Collections.Generic;

namespace Mendi
{

    /// <summary>
    /// class used for logging misc information to log file
    /// written by Mendi Barel
    /// </summary>
    static class DirectLog
    {
        readonly static int SAVE_PERIOD = 10 * 1000;// period=10 seconds
        readonly static int SAVE_COUNTER = 1000;// save after 1000 messages
        readonly static int MIN_IMPORTANCE = 0;// log only messages with importance value >=MIN_IMPORTANCE

        readonly static string DIR_LOG_FILES = @"z:\MyFolder\";

        static string _filename = DIR_LOG_FILES + @"Log." + DateTime.Now.ToString("yyMMdd.HHmm") + @".txt";

        readonly static List<string> _list_log = new List<string>();
        readonly static object _locker = new object();
        static int _counter = 0;
        static DateTime _last_save = DateTime.Now;

        public static void NewFile()
        {//new file is created because filename changed
            SaveToFile();
            lock (_locker)
            {

                _filename = DIR_LOG_FILES + @"Log." + DateTime.Now.ToString("yyMMdd.HHmm") + @".txt";
                _counter = 0;
            }
        }
        public static void Log(string LogMessage, int Importance)
        {
            if (Importance < MIN_IMPORTANCE) return;
            lock (_locker)
            {
                _list_log.Add(String.Format("{0:HH:mm:ss.ffff},{1},{2}", DateTime.Now, LogMessage, Importance));
                _counter++;
            }
            TimeSpan timeDiff = DateTime.Now - _last_save;

            if (_counter > SAVE_COUNTER || timeDiff.TotalMilliseconds > SAVE_PERIOD)
                SaveToFile();
        }

        public static void SaveToFile()
        {
            lock (_locker)
                if (_list_log.Count == 0)
                {
                    _last_save = _last_save = DateTime.Now;
                    return;
                }
            lock (_locker)
            {
                using (StreamWriter logfile = File.AppendText(_filename))
                {

                    foreach (string s in _list_log) logfile.WriteLine(s);
                    logfile.Flush();
                    logfile.Close();
                }

                _list_log.Clear();
                _counter = 0;
                _last_save = DateTime.Now;
            }
        }


        public static void ReadLog(string logfile)
        {
            using (StreamReader r = File.OpenText(logfile))
            {
                string line;
                while ((line = r.ReadLine()) != null)
                {
                    Console.WriteLine(line);
                }
                r.Close();
            }
        }
    }
}

If you just want to show label below the marker, then you can extend google maps Marker to add a setter method for label and you can define the label object by extending google maps overlayView like this..

<script type="text/javascript">
    var point = { lat: 22.5667, lng: 88.3667 };
    var markerSize = { x: 22, y: 40 };


    google.maps.Marker.prototype.setLabel = function(label){
        this.label = new MarkerLabel({
          map: this.map,
          marker: this,
          text: label
        });
        this.label.bindTo('position', this, 'position');
    };

    var MarkerLabel = function(options) {
        this.setValues(options);
        this.span = document.createElement('span');
        this.span.className = 'map-marker-label';
    };

    MarkerLabel.prototype = $.extend(new google.maps.OverlayView(), {
        onAdd: function() {
            this.getPanes().overlayImage.appendChild(this.span);
            var self = this;
            this.listeners = [
            google.maps.event.addListener(this, 'position_changed', function() { self.draw();    })];
        },
        draw: function() {
            var text = String(this.get('text'));
            var position = this.getProjection().fromLatLngToDivPixel(this.get('position'));
            this.span.innerHTML = text;
            this.span.style.left = (position.x - (markerSize.x / 2)) - (text.length * 3) + 10 + 'px';
            this.span.style.top = (position.y - markerSize.y + 40) + 'px';
        }
    });
    function initialize(){
        var myLatLng = new google.maps.LatLng(point.lat, point.lng);
        var gmap = new google.maps.Map(document.getElementById('map_canvas'), {
            zoom: 5,
            center: myLatLng,
            mapTypeId: google.maps.MapTypeId.ROADMAP
        });
        var myMarker = new google.maps.Marker({
            map: gmap,
            position: myLatLng,
            label: 'Hello World!',
            draggable: true
        });
    }
</script>
<style>
    .map-marker-label{
        position: absolute;
    color: blue;
    font-size: 16px;
    font-weight: bold;
    }
</style>

This will work.

Not a lot of the answers here are practical for every day use. Since it is very difficult to do this properly in pure bash, I suggest the following, reliable solution (similar to one suggestion buried in a comment):

function relpath() { 
  python -c "import os,sys;print(os.path.relpath(*(sys.argv[1:])))" "$@";
}

Then, you can get the relative path based upon the current directory:

echo $(relpath somepath)

or you can specify that the path be relative to a given directory:

echo $(relpath somepath /etc)  # relative to /etc

The one disadvantage is this requires python, but:

• It works identically in any python >= 2.6
• It does not require that the files or directories exist.
• Filenames may contain a wider range of special characters. For example, many other solutions do not work if filenames contain spaces or other special characters.
• It is a one-line function that doesn't clutter scripts.

Note that solutions which include basename or dirname may not necessarily be better, as they require that coreutils be installed. If somebody has a pure bash solution that is reliable and simple (rather than a convoluted curiosity), I'd be surprised.

Configure XCode project settings, it can solve your problem.

I looked over everyone's input above, which was very useful, and made a function which was appropriate for my own application. The function is really only evaluating that the user's input is not a "0", but it was good enough for my purpose. Hope this helps!

#include<stdio.h>

int iFunctErrorCheck(int iLowerBound, int iUpperBound){

int iUserInput=0;
while (iUserInput==0){
    scanf("%i", &iUserInput);
    if (iUserInput==0){
        printf("Please enter an integer (%i-%i).\n", iLowerBound, iUpperBound);
        getchar();
    }
    if ((iUserInput!=0) && (iUserInput<iLowerBound || iUserInput>iUpperBound)){
        printf("Please make a valid selection (%i-%i).\n", iLowerBound, iUpperBound);
        iUserInput=0;
    }
}
return iUserInput;
}

From this brilliant blog post... https://blog.josephscott.org/2011/10/14/timing-details-with-curl/

cURL supports formatted output for the details of the request (see the cURL manpage for details, under -w, –write-out <format>). For our purposes we’ll focus just on the timing details that are provided. Times below are in seconds.

1. Create a new file, curl-format.txt, and paste in:

        time_namelookup:  %{time_namelookup}s\n
           time_connect:  %{time_connect}s\n
        time_appconnect:  %{time_appconnect}s\n
       time_pretransfer:  %{time_pretransfer}s\n
          time_redirect:  %{time_redirect}s\n
     time_starttransfer:  %{time_starttransfer}s\n
                        ----------\n
             time_total:  %{time_total}s\n
   

2. Make a request:

    curl -w "@curl-format.txt" -o /dev/null -s "http://wordpress.com/"
   

Or on Windows, it's...

    curl -w "@curl-format.txt" -o NUL -s "http://wordpress.com/"

What this does:

-w "@curl-format.txt" tells cURL to use our format file
-o /dev/null redirects the output of the request to /dev/null
-s tells cURL not to show a progress meter
"http://wordpress.com/" is the URL we are requesting. Use quotes particularly if your URL has "&" query string parameters

And here is what you get back:

   time_namelookup:  0.001s
      time_connect:  0.037s
   time_appconnect:  0.000s
  time_pretransfer:  0.037s
     time_redirect:  0.000s
time_starttransfer:  0.092s
                   ----------
        time_total:  0.164s

Make a Linux/Mac shortcut (alias)

alias curltime="curl -w \"@$HOME/.curl-format.txt\" -o /dev/null -s "

Then you can simply call...

curltime wordpress.org

Thanks to commenter Pete Doyle!

Make a Linux/Mac stand-alone script

This script does not require a separate .txt file to contain the formatting.

Create a new file, curltime, somewhere in your executable path, and paste in:

#!/bin/bash

curl -w @- -o /dev/null -s "$@" <<'EOF'
    time_namelookup:  %{time_namelookup}\n
       time_connect:  %{time_connect}\n
    time_appconnect:  %{time_appconnect}\n
   time_pretransfer:  %{time_pretransfer}\n
      time_redirect:  %{time_redirect}\n
 time_starttransfer:  %{time_starttransfer}\n
                    ----------\n
         time_total:  %{time_total}\n
EOF

Call the same way as the alias:

curltime wordpress.org

Make a Windows shortcut (aka BAT file)

Put this command in CURLTIME.BAT (in the same folder as curl.exe)

curl -w "@%~dp0curl-format.txt" -o NUL -s %*

Then you can simply call...

curltime wordpress.org

If you want to use NodeJS environment variable to set up the value of the port of Angular CLI dev server, following approach is possible:

• create NodeJS script, which will have an access to the environment variable (say, DEV_SERVER_PORT) and could run ng serve with --port parameter value taken from that variable (child_process might be our friend here):

const child_process = require('child_process');
const child = child_process.exec(`ng serve --port=${process.env.DEV_SERVER_PORT}`);
child.stdout.on('data', data => console.log(data.toString()));

• update package.json to provide this script running via npm
• do not forget to set up DEV_SERVER_PORT environment variable (can be done via dotenv)

Here is also the complete description of this approach: How to change Angular CLI Development Server Port via .env.

There is nothing built into Java at the moment of writing this. I would suggest writing your own implementation. My preference is for a simple fluent builder interface instead of creating a map and passing it to function -- you end up with a nice contiguous chunk of code, for example:

String result = new TemplatedStringBuilder("My name is {{name}} and I from {{town}}")
   .replace("name", "John Doe")
   .replace("town", "Sydney")
   .finish();

Here is a simple implementation:

class TemplatedStringBuilder {

    private final static String TEMPLATE_START_TOKEN = "{{";
    private final static String TEMPLATE_CLOSE_TOKEN = "}}";

    private final String template;
    private final Map<String, String> parameters = new HashMap<>();

    public TemplatedStringBuilder(String template) {
        if (template == null) throw new NullPointerException();
        this.template = template;
    }

    public TemplatedStringBuilder replace(String key, String value){
        parameters.put(key, value);
        return this;
    }

    public String finish(){

        StringBuilder result = new StringBuilder();

        int startIndex = 0;

        while (startIndex < template.length()){

            int openIndex  = template.indexOf(TEMPLATE_START_TOKEN, startIndex);

            if (openIndex < 0){
                result.append(template.substring(startIndex));
                break;
            }

            int closeIndex = template.indexOf(TEMPLATE_CLOSE_TOKEN, openIndex);

            if(closeIndex < 0){
                result.append(template.substring(startIndex));
                break;
            }

            String key = template.substring(openIndex + TEMPLATE_START_TOKEN.length(), closeIndex);

            if (!parameters.containsKey(key)) throw new RuntimeException("missing value for key: " + key);

            result.append(template.substring(startIndex, openIndex));
            result.append(parameters.get(key));

            startIndex = closeIndex + TEMPLATE_CLOSE_TOKEN.length();
        }

        return result.toString();
    }
}

I think the simplest solution, rather than making the body element partially transparent, would be to add an extra div to hold the background, and change the opacity there, instead.

So you would add a div like:

<div id="background"></div>

And move your body element's background CSS to it, as well as some additional positioning properties, like this:

#background {
    position: fixed;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    background-image: url('images/background.jpg');
    background-repeat: no-repeat;
    background-attachment: fixed;
    background-size: 100%;
    opacity: 0.8;
    filter:alpha(opacity=80);
}

Here's an example: http://jsfiddle.net/nbVg4/4/

I found that most answers are incomplete here. In case anyone else is still looking for this:

1. Check if you have APP_KEY= in your .env, if not just add it without a value.
2. Run this command: php artisan key:generate. This will fill in the value to the APP_KEY in your .env file.
3. Finally, run php artisan config:cache in order to clear your config cache and recache your config with the new APP_KEY value.

For those who even yet have the problem, try enabling "Build project automatically" in the Java compiler settings and see if that makes a difference as it worked for me.

_{This is now a multiple-year old question, but being very popular, it's worth mentioning a fantastic resource for learning about the C++11 memory model. I see no point in summing up his talk in order to make this yet another full answer, but given this is the guy who actually wrote the standard, I think it's well worth watching the talk.}

Herb Sutter has a three hour long talk about the C++11 memory model titled "atomic<> Weapons", available on the Channel9 site - part 1 and part 2. The talk is pretty technical, and covers the following topics:

1. Optimizations, Races, and the Memory Model
2. Ordering – What: Acquire and Release
3. Ordering – How: Mutexes, Atomics, and/or Fences
4. Other Restrictions on Compilers and Hardware
5. Code Gen & Performance: x86/x64, IA64, POWER, ARM
6. Relaxed Atomics

The talk doesn't elaborate on the API, but rather on the reasoning, background, under the hood and behind the scenes (did you know relaxed semantics were added to the standard only because POWER and ARM do not support synchronized load efficiently?).

For JavaScript arrays, you use Both push() and concat() function.

var array = [1, 2, 3];
array.push(4, 5);         //use push for appending a single array.




var array1 = [1, 2, 3];
var array2 = [4, 5, 6];

var array3 = array1.concat(array2);   //It is better use concat for appending more then one array.

I feel like there should be a no javascript solution, but how is this?

http://jsfiddle.net/NfmX3/2/

$(window).resize(function() {
    $('#content').height($(window).height() - 46);
});

$(window).trigger('resize');

You may use TypeToken to load the json string into a custom object.

logs = gson.fromJson(br, new TypeToken<List<JsonLog>>(){}.getType());

Documentation:

Represents a generic type T.

Java doesn't yet provide a way to represent generic types, so this class does. Forces clients to create a subclass of this class which enables retrieval the type information even at runtime.

For example, to create a type literal for List<String>, you can create an empty anonymous inner class:

TypeToken<List<String>> list = new TypeToken<List<String>>() {};

This syntax cannot be used to create type literals that have wildcard parameters, such as Class<?> or List<? extends CharSequence>.

Kotlin:

If you need to do it in Kotlin you can do it like this:

val myType = object : TypeToken<List<JsonLong>>() {}.type
val logs = gson.fromJson<List<JsonLong>>(br, myType)

Or you can see this answer for various alternatives.

I create the database myself using the command line. Then try to import again, it works.

call function on load:

<video onload="doWhatYouNeedTo()" src="demo.mp4" id="video">

get video duration

var video = document.getElementById("video");
var duration = video.duration;

var the_string = "sometext-20202";
var parts = the_string.split('-', 2);

// After calling split(), 'parts' is an array with two elements:
// parts[0] is 'sometext'
// parts[1] is '20202'

var the_text = parts[0];
var the_num  = parts[1];

On Android >=6.0, We have to request permission runtime.

Step1: add in AndroidManifest.xml file

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

Step2: Request permission.

int permissionCheck = ContextCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE);

if (permissionCheck != PackageManager.PERMISSION_GRANTED) {
    ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_PHONE_STATE}, REQUEST_READ_PHONE_STATE);
} else {
    //TODO
}

Step3: Handle callback when you request permission.

@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case REQUEST_READ_PHONE_STATE:
            if ((grantResults.length > 0) && (grantResults[0] == PackageManager.PERMISSION_GRANTED)) {
                //TODO
            }
            break;

        default:
            break;
    }
}

Edit: Read official guide here Requesting Permissions at Run Time

Use Windows Job Objects. Jobs are like process groups and can limit memory usage and process priority.

I believe you might be missing a "Grant Connect To" statement when you created the database user.

Below is the complete snippet you will need to create both a login against the SQL Server DBMS as well as a user against the database

USE [master]
GO

CREATE LOGIN [SqlServerLogin] WITH PASSWORD=N'Passwordxyz', DEFAULT_DATABASE=[master], CHECK_EXPIRATION=OFF, CHECK_POLICY=ON
GO

USE [myDatabase]
GO

CREATE USER [DatabaseUser] FOR LOGIN [SqlServerLogin] WITH DEFAULT_SCHEMA=[mySchema]
GO

GRANT CONNECT TO [DatabaseUser]
GO

-- the role membership below will allow you to run a test "select" query against the tables in your database
ALTER ROLE [db_datareader] ADD MEMBER [DatabaseUser]
GO

The NEW values (or NEW_BUFFER as you have renamed them) are only available when INSERTING and UPDATING. For DELETING you would need to use OLD (OLD_BUFFER). So your trigger would become:

CREATE or REPLACE TRIGGER test001
  AFTER INSERT OR DELETE OR UPDATE ON tabletest001
  REFERENCING OLD AS old_buffer NEW AS new_buffer 
  FOR EACH ROW WHEN (new_buffer.field1 = 'HBP00' OR old_buffer.field1 = 'HBP00') 

You may need to add logic inside the trigger to cater for code that updates field1 from 'HBP000' to something else.

Solution With Less XAML and More C#

If you define the ListView in XAML:

<ListView x:Name="listView"/>

Then you can add columns and populate it in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Add columns
    var gridView = new GridView();
    this.listView.View = gridView;
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Id", DisplayMemberBinding = new Binding("Id") });
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Name", DisplayMemberBinding = new Binding("Name") });

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

Solution With More XAML and less C#

However, it's easier to define the columns in XAML (inside the ListView definition):

<ListView x:Name="listView">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Id" DisplayMemberBinding="{Binding Id}"/>
            <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}"/>
        </GridView>
    </ListView.View>
</ListView>

And then just populate the list in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

MyItem Definition

MyItem is defined like this:

public class MyItem
{
    public int Id { get; set; }

    public string Name { get; set; }
}

which version are you using?

If the coding standards for the particular codebase I am writing code for specifies which operator should be used, I'll definitely use that. If not, and the code dictates which should be used (not often, can be easily worked around) then I'll use that. Otherwise, probably &&.

Is 'and' more readable than '&&'?

Is it more readable to you. The answer is yes and no depending on many factors including the code around the operator and indeed the person reading it!

|| there is ~ difference?

Yes. See logical operators for || and bitwise operators for ~.

Add &autoplay=1 to your syntax, like this

<iframe title="YouTube video player" width="480" height="390" src="http://www.youtube.com/embed/zGPuazETKkI&amp;autoplay=1" frameborder="0" allowfullscreen></iframe>

Try CSS:

<h2 style="color:#069">Process Report</h2>

If you have more than one h2 tags which should have the same color add a style tag to the head tag like this:

<style type="text/css">
h2 {
    color:#069;
}
</style>

You can try something like process.argv, that is if you are using node.js to run the program.
console.log(process.argv) => Would print an array containing

[                                                                                                                                                                                          
  '/usr/bin/node',                                                                                                                                                                         
  '/home/user/path/filename.js',                                                                                                                                            
  'your_input'                                                                                                                                                                                   
]

You get the user provided input via array index, i.e., console.log(process.argv[3]) This should provide you with the input which you can store.

Example:

var somevariable = process.argv[3]; // input one
var somevariable2 = process.argv[4]; // input two

console.log(somevariable);
console.log(somevariable2);

If you are building a command-line program then the npm package yargs would be really helpful.

ApplicationDeployment.CurrentDeployment.ActivationUri might work

"A zero-length string if the TrustUrlParameters property in the deployment manifest is false, or if the user has supplied a UNC to open the deployment or has opened it locally. Otherwise, the return value is the full URL used to launch the application, including any parameters."

BUT what I think you really want is ApplicationDeployment.CurrentDeployment.DataDirectory which gives you a folder you can write data to. When you update the application anyways you'll lose what was in the original .exe folder, but you can migrate the data directory over to a new version of the app. Your app can write to this folder with whatever log files it has - and I'm pretty sure its guaranteed to be writable.

sudo iptables -I INPUT -s 173.194.0.0/16 -p tcp --tcp-flags RST RST -j DROP
sudo iptables -I INPUT -s 173.194.0.0/16 -p tcp --tcp-flags RST RST -j LOG --log-prefix "drop rst"

sudo iptables -I INPUT -s 64.233.0.0/16 -p tcp --tcp-flags RST RST -j DROP
sudo iptables -I INPUT -s 64.233.0.0/16 -p tcp --tcp-flags RST RST -j LOG --log-prefix "drop rst"

sudo iptables -I INPUT -s 74.125.0.0/16 -p tcp --tcp-flags RST RST -j LOG --log-prefix "drop rst"

Use an associative array:

$code_names = array(
                    'tn' => 'Tunisia',
                    'us' => 'United States',
                    'fr' => 'France');

foreach($code_names as $code => $name) {
   //...
}

I believe that using an associative array is the most sensible approach as opposed to using array_combine() because once you have an associative array, you can simply use array_keys() or array_values() to get exactly the same array you had before.

You need to update the output of json.load with a_dict and then dump the result. And you cannot append to the file but you need to overwrite it.

Starting from Android Studio 2.3.2 now you can create an AVD that has Play Store pre-installed on it. Currently, it is supported on the AVD's running

• A system image since Android 7.0 (API 24)

For other emulators, you can try the solution mentioned in this answer.

Use font property of UILabel:

label.font = UIFont(name:"HelveticaNeue-Bold", size: 16.0)

or use default system font to bold text:

label.font = UIFont.boldSystemFont(ofSize: 16.0)

SYSDATE is an Oracle only function.

The ANSI standard defines current_date or current_timestamp which is supported by Postgres and documented in the manual:
http://www.postgresql.org/docs/current/static/functions-datetime.html#FUNCTIONS-DATETIME-CURRENT

(Btw: Oracle supports CURRENT_TIMESTAMP as well)

You should pay attention to the difference between current_timestamp, statement_timestamp() and clock_timestamp() (which is explained in the manual, see the above link)

This statement:

select up_time from exam where up_time like sysdate

Does not make any sense at all. Neither in Oracle nor in Postgres. If you want to get rows from "today", you need something like:

select up_time 
from exam 
where up_time = current_date

Note that in Oracle you would probably want trunc(up_time) = trunc(sysdate) to get rid of the time part that is always included in Oracle.

Let's say you have to color certain cell (not all cells of the row) by knowing two things:

1. Name or index of the column.
2. Value which is gonna be inside of the cell.

In thas case you have to use event CellFormatting

In my case I use like this

private void DgvTrucksMaster_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
     foreach (DataGridViewRow row in dgvTrucksMaster.Rows)
     {
       if (Convert.ToInt32(row.Cells["Decade1Hours"].Value) > 0)
       {
          row.Cells["Decade1Hours"].Style.BackColor = Color.LightGreen;
       }
       else if (Convert.ToInt32(row.Cells["Decade1Hours"].Value) < 0)
       {
          // row.DefaultCellStyle.BackColor = Color.LightSalmon; // Use it in order to colorize all cells of the row

          row.Cells["Decade1Hours"].Style.BackColor = Color.LightSalmon;
       }
     }
}

And result you can see here

So here you can access certain cell of the row in column by its name row.Cells["Decade1Hours"]

How do you know this name? Well in my case i create column of DataGridView like this.

var Decade1Hours = new DataGridViewTextBoxColumn()
{
   Name = "Decade1Hours",
   Width = 50,
   DataPropertyName = "Decade1Hours",
   ReadOnly = true,
   DefaultCellStyle = new DataGridViewCellStyle()
       {
        Alignment = DataGridViewContentAlignment.MiddleCenter,
        ForeColor = System.Drawing.Color.Black,
        Font = new Font(font, FontStyle.Bold),
        Format = "n2"
      },
   HeaderCell = new DataGridViewColumnHeaderCell()
      {
          Style = new DataGridViewCellStyle()
               {
                 Alignment = DataGridViewContentAlignment.MiddleCenter,
                 BackColor = System.Drawing.Color.Blue
               }
       }
};
Decade1Hours.HeaderText = "???.1";
dgvTrucksMaster.Columns.Add(Decade1Hours);

And well... you you need for instance colorize some of the cells in the row like ##1 4 5 and 8 you have to use cell index (it starts from 0).

And code will lok like

 private void DgvTrucksMaster_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
  foreach (DataGridViewRow row in dgvTrucksMaster.Rows)
  {
    if (Convert.ToInt32(row.Cells[1].Value) > 0 )
    {
      row.Cells[1].Style.BackColor = Color.LightGreen;
    }
  }
}

Specifically: ((depth)). By example, the following prints 1.

declare -i x=0
((x)) && echo $x

x=1
((x)) && echo $x

Follow these steps to run your application on the device connected. 1. Change directories to the root of your Android project and execute: ant debug 2. Make sure the Android SDK platform-tools/ directory is included in your PATH environment variable, then execute: adb install bin/<*your app name*>-debug.apk On your device, locate <*your app name*> and open it.

Create the hash:

hash = {:item1 => 1}

Add a new item to it:

hash[:item2] = 2

Mongo's in-built export is working fine, unless you want to any data manipulation like format date, covert data types etc.

Following command works as charm.

    mongoexport -h localhost -d databse -c collection --type=csv 
    --fields erpNum,orderId,time,status 
    -q '{"time":{"$gt":1438275600000}, "status":{"$ne" :"Cancelled"}}' 
    --out report.csv

The only way to control the size of stack within process is start a new Thread. But you can also control by creating a self-calling sub Java process with the -Xss parameter.

public class TT {
    private static int level = 0;

    public static long fact(int n) {
        level++;
        return n < 2 ? n : n * fact(n - 1);
    }

    public static void main(String[] args) throws InterruptedException {
        Thread t = new Thread(null, null, "TT", 1000000) {
            @Override
            public void run() {
                try {
                    level = 0;
                    System.out.println(fact(1 << 15));
                } catch (StackOverflowError e) {
                    System.err.println("true recursion level was " + level);
                    System.err.println("reported recursion level was "
                            + e.getStackTrace().length);
                }
            }

        };
        t.start();
        t.join();
        try {
            level = 0;
            System.out.println(fact(1 << 15));
        } catch (StackOverflowError e) {
            System.err.println("true recursion level was " + level);
            System.err.println("reported recursion level was "
                    + e.getStackTrace().length);
        }
    }

}

Like Pekka said, it should work this way. I can't reproduce the problem with this self-contained example:

<?php
    $pdo = new PDO('mysql:host=localhost;dbname=test;charset=utf8', 'localonly', 'localonly');
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    $pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);

    $pdo->exec('
        CREATE TEMPORARY TABLE soFoo (
            id int auto_increment,
            first int,
            last int,
            whenadded DATETIME,
            primary key(id)
        )
    ');
    $pdo->exec('INSERT INTO soFoo (first,last,whenadded) VALUES (0,1,Now())');
    $pdo->exec('INSERT INTO soFoo (first,last,whenadded) VALUES (0,2,Now())');
    $pdo->exec('INSERT INTO soFoo (first,last,whenadded) VALUES (0,3,Now())');

    foreach( $pdo->query('SELECT * FROM soFoo', PDO::FETCH_ASSOC) as $row ) {
        echo join(' | ', $row), "\n";
    }

Which (currently) prints

1 | 0 | 1 | 2012-03-23 16:00:18
2 | 0 | 2 | 2012-03-23 16:00:18
3 | 0 | 3 | 2012-03-23 16:00:18

And here's (almost) the same script using a TIMESTAMP field and DEFAULT CURRENT_TIMESTAMP:

<?php
    $pdo = new PDO('mysql:host=localhost;dbname=test;charset=utf8', 'localonly', 'localonly');
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    $pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);

    $pdo->exec('
        CREATE TEMPORARY TABLE soFoo (
            id int auto_increment,
            first int,
            last int,
            whenadded TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
            primary key(id)
        )
    ');
    $pdo->exec('INSERT INTO soFoo (first,last) VALUES (0,1)');
    $pdo->exec('INSERT INTO soFoo (first,last) VALUES (0,2)');
    sleep(1);
    $pdo->exec('INSERT INTO soFoo (first,last) VALUES (0,3)');

    foreach( $pdo->query('SELECT * FROM soFoo', PDO::FETCH_ASSOC) as $row ) {
        echo join(' | ', $row), "\n";
    }

Conveniently, the timestamp is converted to the same datetime string representation as in the first example - at least with my PHP/PDO/mysqlnd version.

As its name is "numbers" it is clear it is a list of number... So an array of number... no need of the attribute type... Although I like the principle of specifying the type of field in a type attribute...

The ascii values of the:

1. Up key - 224 72

2. Down key - 224 80

3. Left key - 224 75

4. Right key - 224 77

Each of these has two integer values for ascii value, because they are special keys, as opposed to the code for $, which is simply 36. These 2 byte special keys usually have the first digit as either 224, or 0. this can be found with the F# in windows, or the delete key.

EDIT : This may actually be unicode looking back, but they do work.

I recommend you exit the Python interpreter with Ctrl-D. This is the old ASCII code for end-of-file or end-of-transmission.

You will have to submit this data to the server somehow. I'm assuming that you don't want to do a full page reload every time a user clicks a link, so you'll have to user XHR (AJAX). If you are not using jQuery (or some other JS library) you can read this tutorial on how to do the XHR request "by hand".

It's not much of an answer, but you might need to go old school and capture an image snapshot of the IIS process and debug it. You might also want to check out Tess Ferrandez's blog - she is a kick a** microsoft escalation engineer and her blog focuses on debugging windows ASP.NET, but the blog is relevant to windows debugging in general. If you select the ASP.NET tag (which is what I've linked to) then you'll see several items that are similar.

Solved this issue in Eclipse 3.5.2. Two completely identical layouts of which one had the warning. Closed down all tabs and when reopening the warning had disappeared.

You are missing setting what field is the Text and Value in the SelectList itself. That is why it does a .ToString() on each object in the list. You could think that given it is a list of SelectListItem it should be smart enough to detect this... but it is not.

u.UserTypeOptions = new SelectList(
    new List<SelectListItem>
    {
        new SelectListItem { Selected = true, Text = string.Empty, Value = "-1"},
        new SelectListItem { Selected = false, Text = "Homeowner", Value = ((int)UserType.Homeowner).ToString()},
        new SelectListItem { Selected = false, Text = "Contractor", Value = ((int)UserType.Contractor).ToString()},
    }, "Value" , "Text", 1);

BTW, you can use a list of array of any type... and then just set the name of the properties that will act as Text and Value.

I think it is better to do it like this:

u.UserTypeOptions = new SelectList(
    new List<SelectListItem>
    {
        new SelectListItem { Text = "Homeowner", Value = ((int)UserType.Homeowner).ToString()},
        new SelectListItem { Text = "Contractor", Value = ((int)UserType.Contractor).ToString()},
    }, "Value" , "Text");

I removed the -1 item, and the setting of each items selected true/false.

Then, in your view:

@Html.DropDownListFor(m => m.UserType, Model.UserTypeOptions, "Select one")

This way, if you set the "Select one" item, and you don't set one item as selected in the SelectList, the UserType will be null (the UserType need to be int? ).

If you need to set one of the SelectList items as selected, you can use:

u.UserTypeOptions = new SelectList(options, "Value" , "Text", userIdToBeSelected);

env VAR=value myScript args ...

Math.round(value) round the value to the nearest whole number.

Use

1) b=(int)(Math.round(a));

2) a=Math.round(a);  
   b=(int)a;

Try wrapping each button in it's own form in your view.

  @using (Html.BeginForm("Action1", "Controller"))
  {
    <input type="submit" value="Button 1" />
  }

  @using (Html.BeginForm("Action2", "Controller"))
  {
    <input type="submit" value="Button 2" />
  }

this method also encounter a deprecate warning:

org.junit.Assert.assertEquals(float expected,float actual) //deprecated

It is because currently junit prefer a third parameter rather than just two float variables input.

The third parameter is delta:

public static void assertEquals(double expected,double actual,double delta) //replacement

this is mostly used to deal with inaccurate Floating point calculations

for more information, please refer this problem: Meaning of epsilon argument of assertEquals for double values

You can run a script, or a more complex parameter to the RUN. Here is an example from a Dockerfile I've downloaded to look at previously:

RUN cd /opt && unzip treeio.zip && mv treeio-master treeio && \
    rm -f treeio.zip && cd treeio && pip install -r requirements.pip

Because of the use of '&&', it will only get to the final 'pip install' command if all the previous commands have succeeded.

In fact, since every RUN creates a new commit & (currently) an AUFS layer, if you have too many commands in the Dockerfile, you will use up the limits, so merging the RUNs (when the file is stable) can be a very useful thing to do.

just seperate the class name with a comma.

Using BalusC's suggestion of implementing Collection i can now hide my primefaces p:dataTable using not empty operator on my dataModel that extends javax.faces.model.ListDataModel

Code sample:

import java.io.Serializable;
import java.util.Collection;
import java.util.List;
import javax.faces.model.ListDataModel;
import org.primefaces.model.SelectableDataModel;

public class EntityDataModel extends ListDataModel<Entity> implements
        Collection<Entity>, SelectableDataModel<Entity>, Serializable {

    public EntityDataModel(List<Entity> data) { super(data); }

    @Override
    public Entity getRowData(String rowKey) {
        // In a real app, a more efficient way like a query by rowKey should be
        // implemented to deal with huge data
        List<Entity> entitys = (List<Entity>) getWrappedData();
        for (Entity entity : entitys) {
            if (Integer.toString(entity.getId()).equals(rowKey)) return entity;
        }
        return null;
    }

    @Override
    public Object getRowKey(Entity entity) {
        return entity.getId();
    }

    @Override
    public boolean isEmpty() {
        List<Entity> entity = (List<Entity>) getWrappedData();
        return (entity == null) || entity.isEmpty();
    }
    // ... other not implemented methods of Collection...
}

Try this:

int dayOfWeek = date.get(Calendar.DAY_OF_WEEK);  
String weekday = new DateFormatSymbols().getShortWeekdays()[dayOfWeek];

If you are working on a Unix system, take advantage of the netrc module in the standard Python library. It reads passwords from a separate text file (.netrc), which has the format decribed here.

Here is a small usage example:

import netrc

# Define which host in the .netrc file to use
HOST = 'mailcluster.loopia.se'

# Read from the .netrc file in your home directory
secrets = netrc.netrc()
username, account, password = secrets.authenticators( HOST )

print username, password

You should replace the old OpenSSL binary file by the new one via a symlink:

sudo ln -sf /usr/local/ssl/bin/openssl `which openssl`

Remember that after this procedure you should reboot the server or restart all the services related to OpenSSL.

I have also one solution. I always use this method. Try this

There's no dedicated "character type" in C language. char is an integer type, same (in that regard) as int, short and other integer types. char just happens to be the smallest integer type. So, just like any other integer type, it can be signed or unsigned.

It is true that (as the name suggests) char is mostly intended to be used to represent characters. But characters in C are represented by their integer "codes", so there's nothing unusual in the fact that an integer type char is used to serve that purpose.

The only general difference between char and other integer types is that plain char is not synonymous with signed char, while with other integer types the signed modifier is optional/implied.

If you have the correct headers defined & are using a non GlibC library (such as Musl C) gcc will also throw error: implicit declaration of function when GNU extensions such as malloc_trim are encountered.

The solution is to wrap the extension & the header:

#if defined (__GLIBC__)
  malloc_trim(0);
#endif

<input type="email" pattern="^[^ ]+@[^ ]+\.[a-z]{2,6}$">

I would consider this more of an old-school C style; it is not really good practice in JavaScript so you should avoid it.

Here is a solution which works (almost perfect) in FF, Opera, Chrome:

    <style>
        html {
            height:100%;
        }

        p {
            page-break-inside: avoid;
            text-align: center;
            width: 128px;display:inline-block; 
            padding: 2px;
            margin: 2px;
            border: 1px solid red; 
            border-radius: 8px;
        }

        a {
            display: block;
            text-decoration: none;
        }

        b {
            display: block;
            color: red;
        }

        body {
            margin: 0px;
            padding: 1%;
            height: 97%; /* less than 98 b/c scroolbar */
            -webkit-column-width: 138px;
            -moz-column-width: 138px;
            column-width: 138px;
       }
    </style>

    <body>
        <p>
            <b>title 1</b>
            <a>link 1</a>
            <a>link 2</a>
            <a>link 3</a>
            <a>link 4</a>
        </p>

        <p>
            <b>title 2</b>
            <a>link 1</a>
            <a>link 2</a>
            <a>link 3</a>
            <a>link 4</a>
            <a>link 5</a>
        </p>
    </body>

The trick is page-break-inside: avoid; on p and column-width on body. It comes with dynamic column count. Text in a may be multi-line and blocks may have different heights.

Maybe someone has something for Edge and IE

When using Set-Content instead of Out-File, you can specify the encoding Byte, which can be used to write a byte array to a file. This in combination with a custom UTF8 encoding which does not emit the BOM gives the desired result:

# This variable can be reused
$utf8 = New-Object System.Text.UTF8Encoding $false

$MyFile = Get-Content $MyPath -Raw
Set-Content -Value $utf8.GetBytes($MyFile) -Encoding Byte -Path $MyPath

The difference to using [IO.File]::WriteAllLines() or similar is that it should work fine with any type of item and path, not only actual file paths.

Task can be made simple javascript without jQuery etc.

<script type="text/javascript">
function showhide() {
document.getElementById("wizard").className = (document.getElementById("wizard").className=="swMain") ? swHide : swMain;
}
</script>

This function is simple if statement that looks if wizard has class swMain and change class to swHide and else if it's not swMain then change to swMain. This code doesn't support multiple class attributes but in this case it is just enough.

Now you have to make css class named swHide that has display: none

Then add on to the button onclick="showhide()"

So easy it is.

Before Java 7:

 BufferedReader br = new BufferedReader(new FileReader("foo.txt"));
 String line;
 while ((line = br.readLine()) != null) {
   System.out.println(line);
 }

• add exception handling
• add closing the stream

Since Java 7, there is no need to close the stream, because it implements autocloseable

try (BufferedReader br = new BufferedReader(new FileReader("foo.txt"))) {
   String line;
   while ((line = br.readLine()) != null) {
       System.out.println(line);
   }
}

Use deepgrep and deepfind. On debian-based systems you can install them by:

sudo apt-get install strigi-utils

Both commands search for nested archives as well. In your case the command would look like:

find . -name "*.jar" | xargs -I {} deepfind {} | grep Hello.class

It's an interesting question, because it shows that there are a lot of different approaches to achieve the same result. Below I show three different implementations.

Default methods in Collection Framework: Java 8 added some methods to the collections classes, that are not directly related to the Stream API. Using these methods, you can significantly simplify the implementation of the non-stream implementation:

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    Map<String, DataSet> result = new HashMap<>();
    multiDataPoints.forEach(pt ->
        pt.keyToData.forEach((key, value) ->
            result.computeIfAbsent(
                key, k -> new DataSet(k, new ArrayList<>()))
            .dataPoints.add(new DataPoint(pt.timestamp, value))));
    return result.values();
}

Stream API with flatten and intermediate data structure: The following implementation is almost identical to the solution provided by Stuart Marks. In contrast to his solution, the following implementation uses an anonymous inner class as intermediate data structure.

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .flatMap(mdp -> mdp.keyToData.entrySet().stream().map(e ->
            new Object() {
                String key = e.getKey();
                DataPoint dataPoint = new DataPoint(mdp.timestamp, e.getValue());
            }))
        .collect(
            collectingAndThen(
                groupingBy(t -> t.key, mapping(t -> t.dataPoint, toList())),
                m -> m.entrySet().stream().map(e -> new DataSet(e.getKey(), e.getValue())).collect(toList())));
}

Stream API with map merging: Instead of flattening the original data structures, you can also create a Map for each MultiDataPoint, and then merge all maps into a single map with a reduce operation. The code is a bit simpler than the above solution:

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .map(mdp -> mdp.keyToData.entrySet().stream()
            .collect(toMap(e -> e.getKey(), e -> asList(new DataPoint(mdp.timestamp, e.getValue())))))
        .reduce(new HashMap<>(), mapMerger())
        .entrySet().stream()
        .map(e -> new DataSet(e.getKey(), e.getValue()))
        .collect(toList());
}

You can find an implementation of the map merger within the Collectors class. Unfortunately, it is a bit tricky to access it from the outside. Following is an alternative implementation of the map merger:

<K, V> BinaryOperator<Map<K, List<V>>> mapMerger() {
    return (lhs, rhs) -> {
        Map<K, List<V>> result = new HashMap<>();
        lhs.forEach((key, value) -> result.computeIfAbsent(key, k -> new ArrayList<>()).addAll(value));
        rhs.forEach((key, value) -> result.computeIfAbsent(key, k -> new ArrayList<>()).addAll(value));
        return result;
    };
}

I know there are a lot of answers to this already but I would like to put in my two cents. When creating a virtual environment in anaconda launcher you still need to install the packages you need. This is deceiving because I assumed since I was using anaconda that packages such as pandas, numpy etc would be include. This is not the case. It gives you a fresh environment with none of those packages installed, at least mine did. All my packages installed into the environment with no problem and work correctly.

Our git repo disk is mounted on AIX box to do BUILD.

It sounds like you mounted the drive on which the git repository is stored on another server, and you are asking how to modify that. If that is the case, this is a bad idea.

The build server should have its own copy of the git repository, and it will be locally managed by git on the build server. The build server's repository will be connected to the "main" git repository with a "remote", and you can issue the command git pull to update the local repository on the build server.

If you don't want to go to the trouble of setting up SSH or a gitolite server or something similar, you can use a file path as the "remote" location. So you could continue to mount the Linux server's file system on the build server, but instead of running the build out of that mounted path, clone the repository into another folder and run it from there.

var p = {"p1": "value1", "p2": "value2", "p3": "value3"};_x000D_
_x000D_
for (var key in p) if (p.hasOwnProperty(key)) {_x000D_
  var value = p[key];_x000D_
  console.log(key, value);_x000D_
}

The logic in the "one-liner" works fine. From personal experience, what has helped me is to assign the statements to variables (in their "True" form) and then use logical operators for the result:

A = year % 4 == 0
B = year % 100 == 0
C = year % 400 == 0

I used '==' in the B statement instead of "!=" and applied 'not' logical operator in the calculation:

leap = A and (not B or C)

This comes in handy with a larger set of conditions, and to simplify the boolean operation where applicable before writing a whole bunch of if statements.

Make sure you didn't by mistake changed the file type of __init__.py files. If, for example, you changed their type to "Text" (instead of "Python"), PyCharm won't analyze the file for Python code. In that case, you may notice that the file icon for __init__.py files is different from other Python files.

To fix, in Settings > Editor > File Types, in the "Recognized File Types" list click on "Text" and in the "File name patterns" list remove __init__.py.

I would use an asynchronous access using a completion block.

This example saves the Google logo to the document directory of the device. (iOS 5+, OSX 10.7+)

NSString *documentDir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject];
NSString *filePath = [documentDir stringByAppendingPathComponent:@"GoogleLogo.png"];

NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"https://www.google.com/images/srpr/logo11w.png"]];
[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue currentQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
    if (error) {
        NSLog(@"Download Error:%@",error.description);
    }
    if (data) {
        [data writeToFile:filePath atomically:YES];
        NSLog(@"File is saved to %@",filePath);
    }
}];

You can start with Instant.ofEpochMilli(long):

LocalDate date =
  Instant.ofEpochMilli(startDateLong)
  .atZone(ZoneId.systemDefault())
  .toLocalDate();

Just for completeness I would like to add my solution. I ended up doing this with the standard ed:

ed -s sometextfile <<< $'-2,$d\nwq'

This deletes the last 2 lines using in-place editing (although it does use a temporary file in /tmp !!)

I'd recommend the Range object's AutoFill method for this:

rngSource.AutoFill Destination:=rngDest

Specify the Source range that contains the values or formulas you want to fill down, and the Destination range as the whole range that you want the cells filled to. The Destination range must include the Source range. You can fill across as well as down.

It works exactly the same way as it would if you manually "dragged" the cells at the corner with the mouse; absolute and relative formulas work as expected.

Here's an example:

'Set some example values'
Range("A1").Value = "1"
Range("B1").Formula = "=NOW()"
Range("C1").Formula = "=B1+A1"

'AutoFill the values / formulas to row 20'
Range("A1:C1").AutoFill Destination:=Range("A1:C20")

Hope this helps.

.htpasswd entries are HASHES. They are not encrypted passwords. Hashes are designed not to be decryptable. Hence there is no way (unless you bruteforce for a loooong time) to get the password from the .htpasswd file.

What you need to do is apply the same hash algorithm to the password provided to you and compare it to the hash in the .htpasswd file. If the user and hash are the same then you're a go.

if the database is InnoDB you dont need to do joins in deletion. only

DELETE FROM spawnlist WHERE spawnlist.type = "monster";

can be used to delete the all the records that linked with foreign keys in other tables, to do that you have to first linked your tables in design time.

CREATE TABLE IF NOT EXIST spawnlist (
  npc_templateid VARCHAR(20) NOT NULL PRIMARY KEY

)ENGINE=InnoDB;

CREATE TABLE IF NOT EXIST npc (
  idTemplate VARCHAR(20) NOT NULL,

  FOREIGN KEY (idTemplate) REFERENCES spawnlist(npc_templateid) ON DELETE CASCADE

)ENGINE=InnoDB;

if you uses MyISAM you can delete records joining like this

DELETE a,b
FROM `spawnlist` a
JOIN `npc` b
ON a.`npc_templateid` = b.`idTemplate`
WHERE a.`type` = 'monster';

in first line i have initialized the two temp tables for delet the record, in second line i have assigned the existance table to both a and b but here i have linked both tables together with join keyword, and i have matched the primary and foreign key for both tables that make link, in last line i have filtered the record by field to delete.

To switch the sign of an integer, you just use the sign operator:

myInt = -myInt;

To make it negative regardless if the original value is negative or not, you first use the Abs method:

myInt = -Math.Abs(myInt);
