I believe you'll find the MVC assembly is referenced in the web.config file, not in the project itself.

Something like this:

<compilation debug="true" targetFramework="4.0">
  <assemblies>
    <add assembly="System.Web.Abstractions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
    <add assembly="System.Web.Routing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
    <add assembly="System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
  </assemblies>
</compilation>

To respond to your comment;

The best answer I can give is from here:

The add element adds an assembly reference to use during compilation of a dynamic resource. ASP.NET automatically links this assembly to the resource when compiling each code module.

I tried it on XP and it doesn't work if the PC is set to International time yyyy-M-d. Place a breakpoint on the line and before it is processed change the date string to use '-' in place of the '/' and you'll find it works. It makes no difference whether you have the CultureInfo or not. Seems strange to be able specify an expercted format only to have the separator ignored.

When creating your own library, you can can create *.d.ts files by using the tsc (TypeScript Compiler) command like so: (assuming you're building your library to the dist/lib folder)

tsc -d --declarationDir dist/lib --declarationMap --emitDeclarationOnly

• -d (--declaration): generates the *.d.ts files
• --declarationDir dist/lib: Output directory for generated declaration files.
• --declarationMap: Generates a sourcemap for each corresponding ‘.d.ts’ file.
• --emitDeclarationOnly: Only emit ‘.d.ts’ declaration files. (no compiled JS)

(see the docs for all command line compiler options)

Or for instance in your package.json:

"scripts": {
    "build:types": "tsc -d --declarationDir dist/lib --declarationMap --emitDeclarationOnly",
}

and then run: yarn build:types (or npm run build:types)

You simply can find a matrix dimension by using Numpy:

import numpy as np

x = np.arange(24).reshape((6, 4))
x.ndim

output will be:

2

It means this matrix is a 2 dimensional matrix.

x.shape

Will show you the size of each dimension. The shape for x is equal to:

(6, 4)

document.getElementById('iframeID').contentWindow.location.href

You can't access cross-domain iframe location at all.

Origin is the shortname that acts like an alias for the url of the remote repository.

Let me explain with an example.

Suppose you have a remote repository called amazing-project and then you clone that remote repository to your local machine so that you have a local repository. Then you would have something like what you can see in the diagram below:

Because you cloned the repository. The remote repository and the local repository are linked.

If you run the command git remote -v it will list all the remote repositories that are linked to your local repository. There you will see that in order to push or fetch code from your remote repository you will use the shortname 'origin'.

Now, this may be a bit confusing because in GitHub (or the remote server) the project is called 'amazing-project'. So why does it seem like there are two names for the remote repository?

Well one of the names that we have for our repository is the name it has on GitHub or a remote server somewhere. This can be kind of thought like a project name. And in our case that is 'amazing-project'.

The other name that we have for our repository is the shortname that it has in our local repository that is related to the URL of the repository. It is the shortname we are going to use whenever we want to push or fetch code from that remote repository. And this shortname kind of acts like an alias for the url, it's a way for us to avoid having to use that entire long url in order to push or fetch code. And in our example above it is called origin.

So, what is origin?

Basically origin is the default shortname that Git uses for a remote repository when you clone that remote repository. So it's just the default.

In many cases you will have links to multiple remote repositories in your local repository and each of those will have a different shortname.

So final question, why don't we just use the same name?

I will answer that question with another example. Suppose we have a friend who forks our remote repository so they can help us on our project. And let's assume we want to be able to fetch code from their remote repository. We can use the command git remote add <shortname> <url> in order to add a link to their remote repository in our local repository.

In the above image you can see that I used the shortname friend to refer to my friend's remote repository. You can also see that both of the remote repositories have the same project name amazing-project and that gives us one reason why the remote repository names in the remote server and the shortnames in our local repositories should not be the same!

There is a really helpful video that explains all of this that can be found here.

Update: ASP.NET Core does not have a SynchronizationContext. If you are on ASP.NET Core, it does not matter whether you use ConfigureAwait(false) or not.

For ASP.NET "Full" or "Classic" or whatever, the rest of this answer still applies.

Original post (for non-Core ASP.NET):

This video by the ASP.NET team has the best information on using async on ASP.NET.

I had read that it is more performant since it doesn't have to switch thread contexts back to the original thread context.

This is true with UI applications, where there is only one UI thread that you have to "sync" back to.

In ASP.NET, the situation is a bit more complex. When an async method resumes execution, it grabs a thread from the ASP.NET thread pool. If you disable the context capture using ConfigureAwait(false), then the thread just continues executing the method directly. If you do not disable the context capture, then the thread will re-enter the request context and then continue to execute the method.

So ConfigureAwait(false) does not save you a thread jump in ASP.NET; it does save you the re-entering of the request context, but this is normally very fast. ConfigureAwait(false) could be useful if you're trying to do a small amount of parallel processing of a request, but really TPL is a better fit for most of those scenarios.

However, with ASP.NET Web Api, if your request is coming in on one thread, and you await some function and call ConfigureAwait(false) that could potentially put you on a different thread when you are returning the final result of your ApiController function.

Actually, just doing an await can do that. Once your async method hits an await, the method is blocked but the thread returns to the thread pool. When the method is ready to continue, any thread is snatched from the thread pool and used to resume the method.

The only difference ConfigureAwait makes in ASP.NET is whether that thread enters the request context when resuming the method.

I have more background information in my MSDN article on SynchronizationContext and my async intro blog post.

Regarding git fetch -p, its behavior changed in Git 1.9, and only Git 2.9.x/2.10 reflects that.

See commit 9e70233 (13 Jun 2016) by Jeff King (peff).
^{(Merged by Junio C Hamano -- gitster -- in commit 1c22105, 06 Jul 2016)}

fetch: document that pruning happens before fetching

This was changed in 10a6cc8 (fetch --prune: Run prune before fetching, 2014-01-02), but it seems that nobody in that discussion realized we were advertising the "after" explicitly.

So the documentation now states:

Before fetching, remove any remote-tracking references that no longer exist on the remote

That is because:

When we have a remote-tracking branch named "frotz/nitfol" from a previous fetch, and the upstream now has a branch named "frotz", fetch would fail to remove "frotz/nitfol" with a "git fetch --prune" from the upstream. git would inform the user to use "git remote prune" to fix the problem.

Change the way "fetch --prune" works by moving the pruning operation before the fetching operation. This way, instead of warning the user of a conflict, it automatically fixes it.

You can either Drop the columns you do not need OR Select the ones you need

# Using DataFrame.drop
df.drop(df.columns[[1, 2]], axis=1, inplace=True)

# drop by Name
df1 = df1.drop(['B', 'C'], axis=1)

# Select the ones you want
df1 = df[['a','d']]

While using simplified tags with AndroidX consider using HtmlCompat.fromHtml()

String s = "<b>Bolded text</b>, <i>italic text</i>, even <u>underlined</u>!"    
TextView tv = (TextView)findViewById(R.id.THE_TEXTVIEW_ID);
tv.setText(HtmlCompat.fromHtml(s, FROM_HTML_MODE_LEGACY));

Yes, they are very different in theory, and in implementation.

Lexers are used to recognize "words" that make up language elements, because the structure of such words is generally simple. Regular expressions are extremely good at handling this simpler structure, and there are very high-performance regular-expression matching engines used to implement lexers.

Parsers are used to recognize "structure" of a language phrases. Such structure is generally far beyond what "regular expressions" can recognize, so one needs "context sensitive" parsers to extract such structure. Context-sensitive parsers are hard to build, so the engineering compromise is to use "context-free" grammars and add hacks to the parsers ("symbol tables", etc.) to handle the context-sensitive part.

Neither lexing nor parsing technology is likely to go away soon.

They may be unified by deciding to use "parsing" technology to recognize "words", as is currently explored by so-called scannerless GLR parsers. That has a runtime cost, as you are applying more general machinery to what is often a problem that doesn't need it, and usually you pay for that in overhead. Where you have lots of free cycles, that overhead may not matter. If you process a lot of text, then the overhead does matter and classical regular expression parsers will continue to be used.

This answer may help if: 1) your site used to work with Windows authentication before upgrading to Visual Studio 2015 and 2) and your site is attempting to load /login.aspx (even though there is no such file on your site).

Add the following two lines to the appSettingssection of your site's Web.config.

<add key="autoFormsAuthentication" value="false" />
<add key="enableSimpleMembership" value="false"/>

If you are using new version of Kafka e.g. 5.3.3, you can use

kafka-broker-api-versions  --bootstrap-server BROKER | grep 9092

You just need to pass one of the brokers

Same as Sergii Pozharov's answer, but with a PowerShell cmdlet:

New-Service -Name "MyService" -BinaryPathName "C:\Path\to\myservice.exe"

See New-Service for more customization.

This will only work for executables that already implement the Windows Services API.

You need to put the entire ternary expression in parenthesis. Unfortunately that means you can't use "@:", but you could do something like this:

@(deletedView ? "Deleted" : "Created by")

Razor currently supports a subset of C# expressions without using @() and unfortunately, ternary operators are not part of that set.

document.getElementById('drpSelectSourceLibrary').value = 'Seven';

In 2020 I use Blob to make local copy of image, which browser will download as a file. You can test it on this site.

(function(global) {
  const next = () => document.querySelector('.search-pagination__button-text').click();
  const uuid = () => Math.random().toString(36).substring(7);
  const toBlob = (src) => new Promise((res) => {
    const img = document.createElement('img');
    const c = document.createElement("canvas");
    const ctx = c.getContext("2d");
    img.onload = ({target}) => {
      c.width = target.naturalWidth;
      c.height = target.naturalHeight;
      ctx.drawImage(target, 0, 0);
      c.toBlob((b) => res(b), "image/jpeg", 0.75);
    };
    img.crossOrigin = "";
    img.src = src;
  });
  const save = (blob, name = 'image.png') => {
    const a = document.createElement("a");
    a.href = URL.createObjectURL(blob);
    a.target = '_blank';
    a.download = name;
    a.click();
  };
  global.download = () => document.querySelectorAll('.search-content__gallery-results figure > img[src]').forEach(async ({src}) => save(await toBlob(src), `${uuid()}.png`));
  global.next = () => next();
})(window);

-is and -as operators requires a type you can compare against. If you're not sure what the type might be, try to evaluate the content (partial type list):

(Invoke-Expression '1.5').GetType().Name -match 'byte|short|int32|long|sbyte|ushort|uint32|ulong|float|double|decimal'

Good or bad, it can work against hex values as well (Invoke-Expression '0xA' ...)

DELETE FROM TBL1  WHERE ID  IN
(SELECT ID FROM TBL1  a WHERE ID!=
(select MAX(ID) from TBL1  where DUPVAL=a.DUPVAL 
group by DUPVAL
having count(DUPVAL)>1))

I had this same issue. I was working with a team of developers using a Mac and everybody else on the team was running Windows. However we were using the Anroid Studio 2.2-beta with jdk 1.8. If you are on a mac and come across this issue, here is how to solve it. DONT USE Android Studio 2.2-beta. I spent hours trying to debug this error in 2.2-beta. I solved it by simply changing to Android Studio 2.1.3. Our app ran instantly after changing the Android Studio version. Also on Android Studio's website before you download it warns mac users about running jdk 1.8 on 2.2 beta. Guess I should have read the fine print haha

An improvement upon previous answers (working on multi-line or tabbed strings):

String.prototype.firstWord = function(){return this.replace(/\s.*/,'')}

Or using search and substr:

String.prototype.firstWord = function(){let sp=this.search(/\s/);return sp<0?this:this.substr(0,sp)}

Or without regex:

String.prototype.firstWord = function(){
  let sps=[this.indexOf(' '),this.indexOf('\u000A'),this.indexOf('\u0009')].
   filter((e)=>e!==-1);
  return sps.length? this.substr(0,Math.min(...sps)) : this;
}

Examples:

String.prototype.firstWord = function(){return this.replace(/\s.*/,'')}_x000D_
console.log(`linebreak_x000D_
example 1`.firstWord()); // -> linebreak_x000D_
console.log('space example 2'.firstWord()); // -> singleline_x000D_
console.log('tab example 3'.firstWord()); // -> tab

ORA-12154: TNS:could not resolve the connect identifier specified?

In case the TNS is not defined you can also try this one:

If you are using C#.net 2010 or other version of VS and oracle 10g express edition or lower version, and you make a connection string like this:

static string constr = @"Data Source=(DESCRIPTION=
    (ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=yourhostname )(PORT=1521)))
    (CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=XE)));
    User Id=system ;Password=yourpasswrd"; 

After that you get error message ORA-12154: TNS:could not resolve the connect identifier specified then first you have to do restart your system and run your project.

And if Your windows is 64 bit then you need to install oracle 11g 32 bit and if you installed 11g 64 bit then you need to Install Oracle 11g Oracle Data Access Components (ODAC) with Oracle Developer Tools for Visual Studio version 11.2.0.1.2 or later from OTN and check it in Oracle Universal Installer Please be sure that the following are checked:

Oracle Data Provider for .NET 2.0

Oracle Providers for ASP.NET

Oracle Developer Tools for Visual Studio

Oracle Instant Client 

And then restart your Visual Studio and then run your project .... NOTE:- SYSTEM RESTART IS necessary TO SOLVE THIS TYPES OF ERROR.......

PlaceHolder control

Use the PlaceHolder control as a container to store server controls that are dynamically added to the Web page. The PlaceHolder control does not produce any visible output and is used only as a container for other controls on the Web page. You can use the Control.Controls collection to add, insert, or remove a control in the PlaceHolder control.

Panel control

The Panel control is a container for other controls. It is especially useful when you want to generate controls programmatically, hide/show a group of controls, or localize a group of controls.

The Direction property is useful for localizing a Panel control's content to display text for languages that are written from right to left, such as Arabic or Hebrew.

The Panel control provides several properties that allow you to customize the behavior and display of its contents. Use the BackImageUrl property to display a custom image for the Panel control. Use the ScrollBars property to specify scroll bars for the control.

Small differences when rendering HTML: a PlaceHolder control will render nothing, but Panel control will render as a <div>.

Of course that works; when @item1 = N'', it IS NOT NULL.

You can define @item1 as NULL by default at the top of your stored procedure, and then not pass in a parameter.

I faced a similar kind of issue while using a custom object as a key in Treemap. Whenever you are using a custom object as a key in hashmap then you override two function equals and hashcode, However if you are using ContainsKey method of Treemap on this object then you need to override CompareTo method as well otherwise you will be getting this error Someone using a custom object as a key in hashmap in kotlin should do like following

 data class CustomObjectKey(var key1:String = "" , var 
 key2:String = ""):Comparable<CustomObjectKey?>
 {
override fun compareTo(other: CustomObjectKey?): Int {
    if(other == null)
        return -1
   // suppose you want to do comparison based on key 1 
    return this.key1.compareTo((other)key1)
}

override fun equals(other: Any?): Boolean {
    if(other == null)
        return false
    return this.key1 == (other as CustomObjectKey).key1
}

override fun hashCode(): Int {
    return this.key1.hashCode()
} 
}

I use :

int convertToInt(char a[1000]){
    int i = 0;
    int num = 0;
    while (a[i] != 0)
    {
        num =  (a[i] - '0')  + (num * 10);
        i++;
    }
    return num;;
}

Sadly, as of this writing, DESPITE their own documentation readme, there is no src.zip in the JDK 7 or 8 install directories when you download the Windows version.

Note: perhaps this happens because many of us don't actually run the install .exe, but instead extract it. Many of us don't run the Java install (the full blown windows install) for security reasons....we just want the JDK put someplace out of the way where potential viruses cannot find it.

But their policy regarding the windows .exe (whatever it truly is) is indeed nuts, HOWEVER, the src.zip DOES exist in the linux install (a .tar.gz). There are multiple ways of extracting a .tar and a .gz, and I prefer the free "7Zip" utility.

1. download the Linux 64 bit .tar.gz
2. use 7zip to uncompress the .tar.gz to a .tar
3. use 7zip to extract the .tar to the installation directory
4. src.zip will be waiting for you in that installation directory.
5. pull it out and place it where you like.

Oracle, this is really beyond stupid.

Try to log the stack trace like below:

logger.error("Exception :: " , e);

It's a difference between RDBMS's varchar (or similar) — those are usually specified with a maximum length, and might be more efficient in terms of performance or storage — and text (or similar) types — those are usually limited only by hardcoded implementation limits (not a DB schema).

PostgreSQL 9, specifically, states that "There is no performance difference among these three types", but AFAIK there are some differences in e.g. MySQL, so this is something to keep in mind.

A good rule of thumb is that you use CharField when you need to limit the maximum length, TextField otherwise.

This is not really Django-specific, also.

You must use the column names and then set the values to insert (both ? marks):

//insert 1st row            
String inserting = "INSERT INTO employee(emp_name ,emp_address) values(?,?)";
System.out.println("insert " + inserting);//
PreparedStatement ps = con.prepareStatement(inserting); 
ps.setString(1, "hans");
ps.setString(2, "germany");
ps.executeUpdate();

I usually don't like to guess, but I'm going to on this one...

If you remember Microsoft's .NET marketing hype back in the day (2001?), it was hard to tell what .NET even was. Was it a server? a programming platform? a language? something new entirely? Given the ads, it was ambiguously anything you wanted it to be - it just solved any problem you might have.

So, my guess is there was a hidden grand vision that ASP.NET code could run anywhere - server side OR client side, in a copy of Internet Explorer tied to the .NET runtime. runat="server" is just a vestigial remnant, left behind because it's client-side equivalent never made it to production.

Remember those weird ads?

Robin Kanters' answer is right, but it does check for installed apps regardless of their enabled or disabled state.

We all know an app can be installed but disabled by the user, therefore unusable.

This checks for installed AND enabled apps:

public static boolean isPackageInstalled(String packageName, PackageManager packageManager) {
    try {
        return packageManager.getApplicationInfo(packageName, 0).enabled;
    }
    catch (PackageManager.NameNotFoundException e) {
        return false;
    }
}

You can put this method in a class like Utils and call it everywhere using:

boolean isInstalled = Utils.isPackageInstalled("com.package.name", context.getPackageManager())

Zoom In

Ctrl++

or

Ctrl+=

Zoom Out

Ctrl+-

This feature is described here:

In text editors, you can now use Zoom In (Ctrl++ or Ctrl+=) and Zoom Out (Ctrl+-) commands to increase and decrease the font size. Like a change in the General > Appearance > Colors and Fonts preference page, the commands persistently change the font size in all editors of the same type. If the editor type's font is configured to use a default font, then that default font will be zoomed.

So, the font size change is not limited to the current file and the new value of the font size is available here Window > Preferences > General > Appearance > Colors and Fonts.

This works fine for 2 tables. I have 3 tables and on clause has to link 2 conditions from 3 tables. My code:

from p in _dbContext.Products join pv in _dbContext.ProductVariants on p.ProduktId equals pv.ProduktId join jpr in leftJoinQuery on new { VariantId = pv.Vid, ProductId = p.ProduktId } equals new { VariantId = jpr.Prices.VariantID, ProductId = jpr.Prices.ProduktID } into lj

But its showing error at this point: join pv in _dbContext.ProductVariants on p.ProduktId equals pv.ProduktId

Error: The type of one of the expressions in the join clause is incorrect. Type inference failed in the call to 'GroupJoin'.

When you call "https://darkorbit.com/" your server figures that it's missing "www" so it redirects the call to "http://www.darkorbit.com/" and then to "https://www.darkorbit.com/", your WebView call is blocked at the first redirection as it's a "http" call. You can call "https://www.darkorbit.com/" instead and it will solve the issue.

This works fine for me:

var arrayOfFieldNames = [];

var items = db.NAMECOLLECTION.find();

while(items.hasNext()) {
  var item = items.next();
  for(var index in item) {
    arrayOfFieldNames[index] = index;
   }
}

for (var index in arrayOfFieldNames) {
  print(index);
}

Because setting the div's display style property to "" doesn't change anything in the CSS rule itself. That basically just creates an "empty," inline CSS rule, which has no effect beyond clearing the same property on that element.

You need to set it to something that has a value:

document.getElementById('mybox').style.display = "block";

What you're doing would work if you were replacing an inline style on the div, like this:

<div id="myBox" style="display: none;"></div>

document.getElementById('mybox').style.display = "";

    personen = null;

    // Deserialize 
    fs = new FileStream("Personenliste.xml", FileMode.Open); 
    personen = (PersonalList)serializer.Deserialize(fs); 
    serializer.Serialize(Console.Out, personen);
    Console.ReadLine();
}

Important is the definition and includes of the diffrent types.

Here's an alternate solution, without using dblink.

Suppose B represents the source database and A represents the target database: Then,

1. Copy table from source DB to target DB:

   pg_dump -t <source_table> <source_db> | psql <target_db>
   

2. Open psql prompt, connect to target_db, and use a simple insert:

   psql
   # \c <target_db>;
   # INSERT INTO <target_table>(id, x, y) SELECT id, x, y FROM <source_table>;
   

3. At the end, delete the copy of source_table that you created in target_table.

   # DROP TABLE <source_table>;
   

Use npm scripts instead... Edit your package.json and add the command to script section.

If you are constrained to using an <img> tag:

I've found it much easier to set a <div> or any other element of your choice with a background-image, width: 100% and background-size: 100%.

This isn't the end all be all to responsive images, but it's a start. Also, try messing around with background-size: cover and maybe some positioning with background-position: center.

CSS:

.image-container{
  height: 100%; /* It doesn't have to be '%'. It can also use 'px'. */
  width: 100%;
  margin: 0 auto;
  padding: 0;

  background-image: url(../img/exampleImage.jpg);
  background-position: top center;
  background-repeat: no-repeat;
  background-size: 100%;
}

HMTL:

<div class="image-container"></div>

var e = $('<div style="display:block; id="myid" float:left;width:'+width+'px; height:'+height+'px; margin-top:'+positionY+'px;margin-left:'+positionX+'px;border:1px dashed #CCCCCC;"></div>');
$("#box").html(e);

On Xcode Version 8.1 (8B62) it can be done directly in Attributes Inspector. Select the textField and then choose the appropriate option from Clear Button drop down box, which is located in Attributes Inspector.

This is the first of my two answers to the question.

If you want fine control over the namespaces - for example if you want to omit some of them but not others, or if you want to replace one namespace with another, you can do this using XmlAttributeOverrides.

Suppose you have this type definition:

// explicitly specify a namespace for this type,
// to be used during XML serialization.
[XmlRoot(Namespace="urn:Abracadabra")]
public class MyTypeWithNamespaces
{
    // private fields backing the properties
    private int _Epoch;
    private string _Label;

    // explicitly define a distinct namespace for this element
    [XmlElement(Namespace="urn:Whoohoo")]
    public string Label
    {
        set {  _Label= value; } 
        get { return _Label; } 
    }

    // this property will be implicitly serialized to XML using the
    // member name for the element name, and inheriting the namespace from
    // the type.
    public int Epoch
    {
        set {  _Epoch= value; } 
        get { return _Epoch; } 
    }
}

And this serialization pseudo-code:

        var o2= new MyTypeWithNamespaces() { ..initializers...};
        ns.Add( "", "urn:Abracadabra" );
        XmlSerializer s2 = new XmlSerializer(typeof(MyTypeWithNamespaces));
        s2.Serialize(System.Console.Out, o2, ns);

You would get something like this XML:

<MyTypeWithNamespaces xmlns="urn:Abracadabra">
  <Label xmlns="urn:Whoohoo">Cimsswybclaeqjh</Label>
  <Epoch>97</Epoch>
</MyTypeWithNamespaces>

Notice that there is a default namespace on the root element, and there is also a distinct namespace on the "Label" element. These namespaces were dictated by the attributes decorating the type, in the code above.

The Xml Serialization framework in .NET includes the possibility to explicitly override the attributes that decorate the actual code. You do this with the XmlAttributesOverrides class and friends. Suppose I have the same type, and I serialize it this way:

        // instantiate the container for all attribute overrides
        XmlAttributeOverrides xOver = new XmlAttributeOverrides();

        // define a set of XML attributes to apply to the root element
        XmlAttributes xAttrs1 = new XmlAttributes();

        // define an XmlRoot element (as if [XmlRoot] had decorated the type)
        // The namespace in the attribute override is the empty string. 
        XmlRootAttribute xRoot = new XmlRootAttribute() { Namespace = ""};

        // add that XmlRoot element to the container of attributes
        xAttrs1.XmlRoot= xRoot;

        // add that bunch of attributes to the container holding all overrides
        xOver.Add(typeof(MyTypeWithNamespaces), xAttrs1);

        // create another set of XML Attributes
        XmlAttributes xAttrs2 = new XmlAttributes();

        // define an XmlElement attribute, for a type of "String", with no namespace
        var xElt = new XmlElementAttribute(typeof(String)) { Namespace = ""};

        // add that XmlElement attribute to the 2nd bunch of attributes
        xAttrs2.XmlElements.Add(xElt);

        // add that bunch of attributes to the container for the type, and
        // specifically apply that bunch to the "Label" property on the type.
        xOver.Add(typeof(MyTypeWithNamespaces), "Label", xAttrs2);

        // instantiate a serializer with the overrides 
        XmlSerializer s3 = new XmlSerializer(typeof(MyTypeWithNamespaces), xOver);

        // serialize
        s3.Serialize(System.Console.Out, o2, ns2);

The result looks like this;

<MyTypeWithNamespaces>
  <Label>Cimsswybclaeqjh</Label>
  <Epoch>97</Epoch>
</MyTypeWithNamespaces>

You have stripped the namespaces.

A logical question is, can you strip all namespaces from arbitrary types during serialization, without going through the explicit overrides? The answer is YES, and how to do it is in my next response.

Easier way, use notice. e.g notice("foo.pp works") or notice($foo)

First, factor consists of indices and levels. This fact is very very important when you are struggling with factor.

For example,

> z <- factor(letters[c(3, 2, 3, 4)])

# human-friendly display, but internal structure is invisible
> z
[1] c b c d
Levels: b c d

# internal structure of factor
> unclass(z)
[1] 2 1 2 3
attr(,"levels")
[1] "b" "c" "d"

here, z has 4 elements.
The index is 2, 1, 2, 3 in that order.
The level is associated with each index: 1 -> b, 2 -> c, 3 -> d.

Then, as.numeric converts simply the index part of factor into numeric.
as.character handles the index and levels, and generates character vector expressed by its level.

?as.numeric says that Factors are handled by the default method.

I know this is 5 years later, but the replies above don't address what was wrong with your software. (Well, Yuushi's does, but I didn't realise until I had typed this - doh!). They answer the question in the title How can I initialize C++ object member variables in the constructor? This is about the other questions: Am I using the right approach but the wrong syntax? Or should I be coming at this from a different direction?

Programming style is largely a matter of opinion, but an alternative view to doing as much as possible in a constructor is to keep constructors down to a bare minimum, often having a separate initialization function. There is no need to try to cram all initialization into a constructor, never mind trying to force things at times into the constructors initialization list.

So, to the point, what was wrong with your software?

private:
    ThingOne* ThingOne;
    ThingTwo* ThingTwo;

Note that after these lines, ThingOne (and ThingTwo) now have two meanings, depending on context.

Outside of BigMommaClass, ThingOne is the class you created with #include "ThingOne.h"

Inside BigMommaClass, ThingOne is a pointer.

That is assuming the compiler can even make sense of the lines and doesn't get stuck in a loop thinking that ThingOne is a pointer to something which is itself a pointer to something which is a pointer to ...

Later, when you write

this->ThingOne = ThingOne(100);
this->ThingTwo = ThingTwo(numba1, numba2);

bear in mind that inside of BigMommaClass your ThingOne is a pointer.

If you change the declarations of the pointers to include a prefix (p)

private:
    ThingOne* pThingOne;
    ThingTwo* pThingTwo;

Then ThingOne will always refer to the class and pThingOne to the pointer.

It is then possible to rewrite

this->ThingOne = ThingOne(100);
this->ThingTwo = ThingTwo(numba1, numba2);

as

pThingOne = new ThingOne(100);
pThingTwo = new ThingTwo(numba1, numba2);

which corrects two problems: the double meaning problem, and the missing new. (You can leave this-> if you like!)

With that in place, I can add the following lines to a C++ program of mine and it compiles nicely.

class ThingOne{public:ThingOne(int n){};};
class ThingTwo{public:ThingTwo(int x, int y){};};

class BigMommaClass {

    public:
            BigMommaClass(int numba1, int numba2);

    private:
            ThingOne* pThingOne;
            ThingTwo* pThingTwo;
};

BigMommaClass::BigMommaClass(int numba1, int numba2)
{
    pThingOne = new ThingOne(numba1 + numba2);
    pThingTwo = new ThingTwo(numba1, numba2);
};

When you wrote

this->ThingOne = ThingOne(100);
this->ThingTwo = ThingTwo(numba1, numba2);

the use of this-> tells the compiler that the left hand side ThingOne is intended to mean the pointer. However we are inside BigMommaClass at the time and it's not necessary.

The problem is with the right hand side of the equals where ThingOne is intended to mean the class. So another way to rectify your problems would have been to write

this->ThingOne = new ::ThingOne(100);
this->ThingTwo = new ::ThingTwo(numba1, numba2);

or simply

ThingOne = new ::ThingOne(100);
ThingTwo = new ::ThingTwo(numba1, numba2);

using :: to change the compiler's interpretation of the identifier.

Did you recently updated your eclipse android plugin (adt r17)? Then the following link might help:

How to fix the classdefnotfounderror with adt-17

Update: One year has passed since the question arose. I will keep the link, because even in 2013 it seem to help some people to solve the problem. But please take care what you are doing, see Erics comment below. Current ADT-Version is 22, I recommend using the most current version.

<input id="inputFileToLoad" type="file" onchange="encodeImageFileAsURL();" />
<div id="imgTest"></div>
<script type='text/javascript'>
  function encodeImageFileAsURL() {

    var filesSelected = document.getElementById("inputFileToLoad").files;
    if (filesSelected.length > 0) {
      var fileToLoad = filesSelected[0];

      var fileReader = new FileReader();

      fileReader.onload = function(fileLoadedEvent) {
        var srcData = fileLoadedEvent.target.result; // <--- data: base64

        var newImage = document.createElement('img');
        newImage.src = srcData;

        document.getElementById("imgTest").innerHTML = newImage.outerHTML;
        alert("Converted Base64 version is " + document.getElementById("imgTest").innerHTML);
        console.log("Converted Base64 version is " + document.getElementById("imgTest").innerHTML);
      }
      fileReader.readAsDataURL(fileToLoad);
    }
  }

Wow. I know this is an ancient thread but all I can say is do not call TimeZone.setDefault() in any user-level code. This always sets the Timezone for the whole JVM and is nearly always a very bad idea. Learn to use the joda.time library or the new DateTime class in Java 8 which is very similar to the joda.time library.

Maybe try this code:

void wait (double x) {
    DateTime t = DateTime.Now;
    DateTime tf = DateTime.Now.AddSeconds(x);

    while (t < tf) {
        t = DateTime.Now;
    }
}

As long as you are using CREATE TABLE, if you are creating the primary key on a single field, you can use:

CREATE TABLE mytable (
field1 TEXT,
field2 INTEGER PRIMARY KEY,
field3 BLOB,
);

With CREATE TABLE, you can also always use the following approach to create a primary key on one or multiple fields:

CREATE TABLE mytable (
field1 TEXT,
field2 INTEGER,
field3 BLOB,
PRIMARY KEY (field2, field1)
);

Reference: http://www.sqlite.org/lang_createtable.html

This answer does not address table alteration.

This may not be the exact definition but I'll give you an example: If you were to create a random number taking it from the system time, here using the unsigned variable is beneficial as there is large scope for random numbers as signed numbers give both positive and negative numbers. As the system time can't be negative we use unsigned variable(Only positive numbers) and we have more wide range of random numbers.

Try this. Works fine in ICS. If You want to stop service simply click the notification generated in statusbar.

                        | WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE, PixelFormat.TRANSLUCENT);
        params.gravity=Gravity.TOP|Gravity.LEFT;

             });
            // Add layout to window manager
            wm.addView(myView, params); 
    }
}

UPDATE

Sample here

To create an overlay view, when setting up the LayoutParams DON'T set the type to TYPE_SYSTEM_OVERLAY.

Instead set it to TYPE_PHONE.

Use the following flags:

FLAG_NOT_TOUCH_MODAL

FLAG_WATCH_OUTSIDE_TOUCH

If you use Sass,

according to the documentation you can customize your default values.

In your case, you can easily override the variable named $modal-lg in your _custom.scss file.

Also something important to add here, in order to set default values for arrays and objects we must use the default function for props:

propE: {
      type: Object,
      // Object or array defaults must be returned from
      // a factory function
      default: function () {
        return { message: 'hello' }
      }
    },

It means there is a problem with the build path in your project. If it is an android project then it mostly means the target value specified in project.properties file cannot be found. This can also be caused because of other kinds of built problems. But it is shown mostly for built problems only. See here for more details. It is about built error decorater seen in eclipse.

An extract from that page:

Build path problems are sometimes easy to miss among other problems in a project. The Package Explorer and Project Explorer views now show a new decorator on Java projects and working sets that contain build path errors:

The concrete errors can be seen in the Problems view, and if you open the view menu and select Group By > Java Problem Type, they all show up in the Build Path category:

I tried the @Alexander Farber and @Sino Raj answers. Both answers are nice, but I couldn't use the onCreateOptionsMenu inside my fragment, until I discover what was missing:

Add setSupportActionBar(toolbar) in my Activity, like this:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.id.activity_main);

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
}

I hope this answer can be helpful for someone with the same problem.

In Xterm-compatible terminals, you can show the image directly in the terminal. See my answer to "PPM image to ASCII art in Python"

I recently used prettytable for rendering a nice ASCII table. It's similar to the postgres CLI output.

import pandas as pd
from prettytable import PrettyTable

data = [[1,2,3],[4,5,6],[7,8,9]]
df = pd.DataFrame(data, columns=['one', 'two', 'three'])

def generate_ascii_table(df):
    x = PrettyTable()
    x.field_names = df.columns.tolist()
    for row in df.values:
        x.add_row(row)
    print(x)
    return x

generate_ascii_table(df)

Output:

+-----+-----+-------+
| one | two | three |
+-----+-----+-------+
|  1  |  2  |   3   |
|  4  |  5  |   6   |
|  7  |  8  |   9   |
+-----+-----+-------+

None of the answers above show a concrete example using massive arrays populated by non-numeric members. Here is an example using an array generated by explode() on a large .txt file (262MB in my use case):

<?php

ini_set('memory_limit','1000M');

echo "Starting memory usage: " . memory_get_usage() . "<br>";

$path = './file.txt';
$content = file_get_contents($path);

foreach(explode("\n", $content) as $ex) {
    $ex = trim($ex);
}

echo "Final memory usage: " . memory_get_usage();

The output was:

Starting memory usage: 415160
Final memory usage: 270948256

Now compare that to a similar script, using the yield keyword:

<?php

ini_set('memory_limit','1000M');

echo "Starting memory usage: " . memory_get_usage() . "<br>";

function x() {
    $path = './file.txt';
    $content = file_get_contents($path);
    foreach(explode("\n", $content) as $x) {
        yield $x;
    }
}

foreach(x() as $ex) {
    $ex = trim($ex);
}

echo "Final memory usage: " . memory_get_usage();

The output for this script was:

Starting memory usage: 415152
Final memory usage: 415616

Clearly memory usage savings were considerable (?MemoryUsage -----> ~270.5 MB in first example, ~450B in second example).

From the use of 8080 I'm assuming you are using a tomcat servlet container to serve your rest api. If this is the case you can also consider to have your webserver proxy the requests to the servlet container.

With apache you would typically use mod_jk (although there are other alternatives) to serve the api trough the web server behind port 80 instead of 8080 which would solve the cross domain issue.

This is common practice, have the 'static' content in the webserver and dynamic content in the container, but both served from behind the same domain.

The url for the rest api would be http://localhost/restws/json/product/get

Here a description on how to use mod_jk to connect apache to tomcat: http://tomcat.apache.org/connectors-doc/webserver_howto/apache.html

Problems only surface when I am I trying to give the first loaded content an active state

Does this mean that you want to add a class to the first button?

$('.o-links').click(function(e) {   // ... }).first().addClass('O_Nav_Current'); 

instead of using IDs for the slider's items and resetting html contents you can use classes and indexes:

CSS:

.image-area {     width: 100%;     height: auto;     display: none; }  .image-area:first-of-type {     display: block; } 

JavaScript:

var $slides = $('.image-area'),     $btns = $('a.o-links');  $btns.on('click', function (e) {     var i = $btns.removeClass('O_Nav_Current').index(this);     $(this).addClass('O_Nav_Current');      $slides.filter(':visible').fadeOut(1000, function () {         $slides.eq(i).fadeIn(1000);     });      e.preventDefault();  }).first().addClass('O_Nav_Current');

This work for Checkbox too.

public class EnumToBoolConverter:IValueConverter
{
    private int val;
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        int intParam = (int)parameter;
        val = (int)value;

        return ((intParam & val) != 0);
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        val ^= (int)parameter;
        return Enum.Parse(targetType, val.ToString());
    }
}

Binding a single enum to multiple checkboxes.

I'm unsure of the context on why this was needed, so this may not return enough information for you but this is what I was able to do:

if(typeof(ModelName).GetProperty("Name of Property") != null)
{
//whatevver you were wanting to do.
}

In my case I'm running through properties from a form submission and also have default values to use if the entry is left blank - so I needed to know if the there was a value to use - I prefixed all my default values in the model with Default so all I needed to do is check if there was a property that started with that.

Also consider next approach:

CSS:

.parent {
  height: 100%;
}
.parent:after {
  content: '';
  display: block;
}

Also since you are trying to reposition divs consider css grid

I think that Joseph flipped controller and action. First comes the action then the controller. This is somewhat strange, but the way the signature looks.

Just to clarify things, this is the version that works (adaption of Joseph's example):

Html.ActionLink(article.Title, 
    "Login",  // <-- ActionMethod
    "Item",   // <-- Controller Name
    new { id = article.ArticleID }, // <-- Route arguments.
    null  // <-- htmlArguments .. which are none
    )

Brian beat me too it, but since I already have the transcript:

Should work:

/**
 * Returns start of most recent Sunday.
 * 
 * @param null|int $timestamp
 * @return int
 */
public static function StartOfWeek($timestamp = null) {
    if($timestamp === null) $timestamp = time();
    $dow = idate('w', $timestamp); // Sunday = 0, Monday = 1, etc.
    return mktime(0, 0, 0, idate('m', $timestamp), idate('d', $timestamp) - $dow, idate('Y', $timestamp));
}

Input and output are unix timestamps. Use date to format.

Yes, just create a directory in your solution like lib/, and then add your dll to that directory in the filesystem and add it in the project (Add->Existing Item->etc). Then add the reference based on your project.

I have done this several times under svn and under cvs.

Very simple piece of code to do this

$date - extract(day from $date) + 1

two ways to do this:

1. my_date - extract(day from my_date) + 1

2. '2014/01/21' - extract(day from '2014/01/21') + 1

I think, better way is use HttpPostedFileBase in your controller or API. After this you can simple detect size, type etc.

File properties you can find here:

MVC3 How to check if HttpPostedFileBase is an image

For example ImageApi:

[HttpPost]
[Route("api/image")]  
public ActionResult Index(HttpPostedFileBase file)  
{  
    if (file != null && file.ContentLength > 0)  
        try 
        {  
            string path = Path.Combine(Server.MapPath("~/Images"),  
               Path.GetFileName(file.FileName));

            file.SaveAs(path);  
            ViewBag.Message = "Your message for success";  
        }  
        catch (Exception ex)  
        {  
            ViewBag.Message = "ERROR:" + ex.Message.ToString();  
        }  
    else 
    {  
        ViewBag.Message = "Please select file";  
    }  
    return View();  
}

Hope it help.

URL url = new URL(yourUrl, "/api/v1/status.xml");

According to the javadocs this constructor just appends whatever resource to the end of your domain, so you would want to create 2 urls:

URL domain = new URL("http://example.com");
URL url = new URL(domain + "/files/resource.xml");

Sources: http://docs.oracle.com/javase/6/docs/api/java/net/URL.html

There is a standard function in R for that

tabulate(numbers)

Recall that according to official MongoDB documentation, the right command to start the service is (@Ubuntu): sudo service mongod start (06/2018) (no mongodb or mongo).

Reference: https://docs.mongodb.com/manual/tutorial/install-mongodb-on-ubuntu/

Sometimes I need to extract several command line parameters, but not all of them and not from the first one. Let's assume the following call:

Test.bat uno dos tres cuatro cinco seis siete

Of course, the extension ".bat" is not needed at least you have test.exe in same folder. What we want is to get the output "tres cuatro cinco" (no matter if one line or three). The goal is that only I need three parameters and starting in the third one. In order to have a simple example the action for each one is just "echo", but you can think in some other more complex action over the selected parameters.

I've produced some examples, (options) in order you can see which one you consider better for you. Unfortunately, there is not a nice (or I don't know about) way based on a for loop over the range like "for %%i in (%3, 1, %5)".

@echo off 
setlocal EnableDelayedExpansion

echo Option 1: one by one (same line)
echo %3, %4, %5
echo.

echo Option 2: Loop For one by one
for %%a in (%3, %4, %5) do echo %%a
echo.

echo Option 3: Loop For with check of limits
set i=0
for %%a in (%*) do (
    set /A i=i+1
    If !i! GTR 2 if !i! LSS 6 echo %%a
)
echo.

echo Option 4: Loop For with auxiliary list
for /l %%i in (3,1,5) do  (
    set a=%%i
    set b=echo %%
    set b=!b!!a!
    call !b!
)
echo.

echo Option 5: Assigning to an array of elements previously
set e[0]=%0
set i=0 
for %%a in (%*) do (
    set /A i=i+1
    set e[!i!]=%%a
)
for  /l %%i in (3,1,5) do (
    echo !e[%%i]!
)
echo.

echo Option 6: using shift and goto loop. It doesn't work with for loop
set i=2
:loop6
    set /A i=i+1
    echo %3
    shift
    If %i% LSS 5 goto :loop6

Probably you can find more options or combine several ones. Enjoy them.

I made one that you can access with any textarea element you like:

function textControl (element, event)
{
    if(event.keyCode==9 || event.which==9)
    {
        event.preventDefault();
        var s = element.selectionStart;
        element.value = element.value.substring(0,element.selectionStart) + "\t" + element.value.substring(element.selectionEnd);
        element.selectionEnd = s+1; 
    }
}

And the element would look like this:

<textarea onkeydown="textControl(this,event)"></textarea>

A cleaner alternative would be to use a Dictionary to handle parameters. They are key-value pairs after all.

private static readonly HttpClient httpclient;

static MyClassName()
{
    // HttpClient is intended to be instantiated once and re-used throughout the life of an application. 
    // Instantiating an HttpClient class for every request will exhaust the number of sockets available under heavy loads. 
    // This will result in SocketException errors.
    // https://docs.microsoft.com/en-us/dotnet/api/system.net.http.httpclient?view=netframework-4.7.1
    httpclient = new HttpClient();    
} 

var url = "http://myserver/method";
var parameters = new Dictionary<string, string> { { "param1", "1" }, { "param2", "2" } };
var encodedContent = new FormUrlEncodedContent (parameters);

var response = await httpclient.PostAsync (url, encodedContent).ConfigureAwait (false);
if (response.StatusCode == HttpStatusCode.OK) {
    // Do something with response. Example get content:
    // var responseContent = await response.Content.ReadAsStringAsync ().ConfigureAwait (false);
}

Also dont forget to Dispose() httpclient, if you dont use the keyword using

As stated in the Remarks section of the HttpClient class in the Microsoft docs, HttpClient should be instantiated once and re-used.

Edit:

You may want to look into response.EnsureSuccessStatusCode(); instead of if (response.StatusCode == HttpStatusCode.OK).

You may want to keep your httpclient and dont Dispose() it. See: Do HttpClient and HttpClientHandler have to be disposed?

Edit:

Do not worry about using .ConfigureAwait(false) in .NET Core. For more details look at https://blog.stephencleary.com/2017/03/aspnetcore-synchronization-context.html

For Oracle 11g (11.1.0.7.20) I had to add the following dlls along with my Exe to work.

3. oraociicus11.dll (pretty huge close to 30mb)
4. Oracle.DataAccess.dll

I did not see this exact syntax posted yet, and it worked for me in an ES6/Webpack environment:

See on the Wikipedia article on bootstrapping.

There is a section and links explaining what it means in Computing. It has four different uses in the field.

Here are some quotes, but for a more in depth explanation, and alternative meanings, consult the links above.

"...is a technique by which a simple computer program activates a more complicated system of programs."

"A different use of the term bootstrapping is to use a compiler to compile itself, by first writing a small part of a compiler of a new programming language in an existing language to compile more programs of the new compiler written in the new language."

After a lot of trial and error with directory permissions I ended up with an epiphany...there was no space left on the disk's partition. Just wanted to share to make sure nobody else is stupid enough to keep looking for the solution in the wrong direction.

In Linux you can use df -h to check your disk size and free space.

You can use Server.Map path to give relative path and then you can either create image using base64 conversion or you can just add base64 string to image src.

byte[] imageArray = System.IO.File.ReadAllBytes(Server.MapPath("~/Images/Upload_Image.png"));

string base64ImageRepresentation = Convert.ToBase64String(imageArray);

I have had numerous problems with opencv and only succeded after a gruesome 4-6 months. This is the last problem I have had, but all of the above didn't work. What worked for me was just copying and pasting the opencv_core2*.dll (and opencv_highgui2*.dll which it will ask for since you included this as well) into the release (or debug folder - I'm assuming. Haven't tested this) folder of your project, where your application file is.

Hope this helps!

Support for BUILD_PATH just landed into v4.0.2.

Add BUILD_PATH variable to .env file and run build script command:

// .env file
BUILD_PATH=foo 

That should place all build files into foo folder.

It's a little roundabout, but why not use URI? It has a relativize method which does all the necessary checks for you.

String path = "/var/data/stuff/xyz.dat";
String base = "/var/data";
String relative = new File(base).toURI().relativize(new File(path).toURI()).getPath();
// relative == "stuff/xyz.dat"

Please note that for file path there's java.nio.file.Path#relativize since Java 1.7, as pointed out by @Jirka Meluzin in the other answer.

You're on the right track - the keyword you should be googling is Regular Expressions. R does support them in a more direct way than this using grep() and a few other alternatives.

Here's a detailed discussion: http://www.regular-expressions.info/rlanguage.html

Try this

package main

import "fmt"
import "strconv"

func FloatToString(input_num float64) string {
    // to convert a float number to a string
    return strconv.FormatFloat(input_num, 'f', 6, 64)
}

func main() {
    fmt.Println(FloatToString(21312421.213123))
}

If you just want as many digits precision as possible, then the special precision -1 uses the smallest number of digits necessary such that ParseFloat will return f exactly. Eg

strconv.FormatFloat(input_num, 'f', -1, 64)

Personally I find fmt easier to use. (Playground link)

fmt.Printf("x = %.6f\n", 21312421.213123)

Or if you just want to convert the string

fmt.Sprintf("%.6f", 21312421.213123)

The standard streams have a boolalpha flag that determines what gets displayed -- when it's false, they'll display as 0 and 1. When it's true, they'll display as false and true.

There's also an std::boolalpha manipulator to set the flag, so this:

#include <iostream>
#include <iomanip>

int main() {
    std::cout<<false<<"\n";
    std::cout << std::boolalpha;   
    std::cout<<false<<"\n";
    return 0;
}

...produces output like:

0
false

For what it's worth, the actual word produced when boolalpha is set to true is localized--that is, <locale> has a num_put category that handles numeric conversions, so if you imbue a stream with the right locale, it can/will print out true and false as they're represented in that locale. For example,

#include <iostream>
#include <iomanip>
#include <locale>

int main() {
    std::cout.imbue(std::locale("fr"));

    std::cout << false << "\n";
    std::cout << std::boolalpha;
    std::cout << false << "\n";
    return 0;
}

...and at least in theory (assuming your compiler/standard library accept "fr" as an identifier for "French") it might print out faux instead of false. I should add, however, that real support for this is uneven at best--even the Dinkumware/Microsoft library (usually quite good in this respect) prints false for every language I've checked.

The names that get used are defined in a numpunct facet though, so if you really want them to print out correctly for particular language, you can create a numpunct facet to do that. For example, one that (I believe) is at least reasonably accurate for French would look like this:

#include <array>
#include <string>
#include <locale>
#include <ios>
#include <iostream>

class my_fr : public std::numpunct< char > {
protected:
    char do_decimal_point() const { return ','; }
    char do_thousands_sep() const { return '.'; }
    std::string do_grouping() const { return "\3"; }
    std::string do_truename() const { return "vrai";  }
    std::string do_falsename() const { return "faux"; }
};

int main() {
    std::cout.imbue(std::locale(std::locale(), new my_fr));

    std::cout << false << "\n";
    std::cout << std::boolalpha;
    std::cout << false << "\n";
    return 0;
}

And the result is (as you'd probably expect):

0
faux

Let's take a look at what happens when you select a file and submit your form (I've truncated the headers for brevity):

POST /upload?upload_progress_id=12344 HTTP/1.1
Host: localhost:3000
Content-Length: 1325
Origin: http://localhost:3000
... other headers ...
Content-Type: multipart/form-data; boundary=----WebKitFormBoundaryePkpFF7tjBAqx29L

------WebKitFormBoundaryePkpFF7tjBAqx29L
Content-Disposition: form-data; name="MAX_FILE_SIZE"

100000
------WebKitFormBoundaryePkpFF7tjBAqx29L
Content-Disposition: form-data; name="uploadedfile"; filename="hello.o"
Content-Type: application/x-object

... contents of file goes here ...
------WebKitFormBoundaryePkpFF7tjBAqx29L--

NOTE: each boundary string must be prefixed with an extra --, just like in the end of the last boundary string. The example above already includes this, but it can be easy to miss. See comment by @Andreas below.

Instead of URL encoding the form parameters, the form parameters (including the file data) are sent as sections in a multipart document in the body of the request.

In the example above, you can see the input MAX_FILE_SIZE with the value set in the form, as well as a section containing the file data. The file name is part of the Content-Disposition header.

The full details are here.

The var keyword in Javascript is there for a purpose.

If you declare a variable without the var keyword, like this:

myVar = 100;

It becomes a global variable that can be accessed from any part of your script. If you did not do it intentionally or are not aware of it, it can cause you pain if you re-use the variable name at another place in your javascript.

If you declare the variable with the var keyword, like this:

var myVar = 100;

It is local to the scope ({] - braces, function, file, depending on where you placed it).

This a safer way to treat variables. So unless you are doing it on purpose try to declare variable with the var keyword and not without.

What is Stroke:

The BasicStroke class defines a basic set of rendering attributes for the outlines of graphics primitives, which are rendered with a Graphics2D object that has its Stroke attribute set to this BasicStroke.

https://docs.oracle.com/javase/7/docs/api/java/awt/BasicStroke.html

Note that the Stroke setting:

Graphics2D g2 = (Graphics2D) g;
g2.setStroke(new BasicStroke(10));

is setting the line width,since BasicStroke(float width):

Constructs a solid BasicStroke with the specified line width and with default values for the cap and join styles.

And, it also effects other methods like Graphics2D.drawLine(int x1, int y1, int x2, int y2) and Graphics2D.drawRect(int x, int y, int width, int height):

The methods of the Graphics2D interface that use the outline Shape returned by a Stroke object include draw and any other methods that are implemented in terms of that method, such as drawLine, drawRect, drawRoundRect, drawOval, drawArc, drawPolyline, and drawPolygon.

Those are not files (they don't exist on disk) - they are just names under which some HTTP handlers are registered. Take a look at the web.config in .NET Framework's directory (e.g. C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\web.config):

<configuration>
  <system.web>
    <httpHandlers>
      <add path="eurl.axd" verb="*" type="System.Web.HttpNotFoundHandler" validate="True" />
      <add path="trace.axd" verb="*" type="System.Web.Handlers.TraceHandler" validate="True" />
      <add path="WebResource.axd" verb="GET" type="System.Web.Handlers.AssemblyResourceLoader" validate="True" />
      <add verb="*" path="*_AppService.axd" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="False" />
      <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="False"/>
      <add path="*.axd" verb="*" type="System.Web.HttpNotFoundHandler" validate="True" />
    </httpHandlers>
  </system.web>
<configuration>

You can register your own handlers with a whatever.axd name in your application's web.config. While you can bind your handlers to whatever names you like, .axd has the upside of working on IIS6 out of the box by default (IIS6 passes requests for *.axd to the ASP.NET runtime by default). Using an arbitrary path for the handler, like Document.pdf (or really anything except ASP.NET-specific extensions), requires more configuration work. In IIS7 in integrated pipeline mode this is no longer a problem, as all requests are processed by the ASP.NET stack.

In my case I wanted to show a print screen on Github but also on NPM. Even though using the relative path was working within Github, it wasn't working outside of it. Basically, even if I pushed my project to NPM as well (which simply uses the same readme.md, the image was never showing.

I tried a few ways, at the end this is what worked for me:

![Preview](https://raw.githubusercontent.com/username/project/master/image-path/image.png)

I now see my image correctly on NPM or anywhere else that I could publish my package.

One or more of your .cpp files is not being linked in, or some non-inline functions in some class are not defined. In particular, takeaway::textualGame()'s implementation can't be found. Note that you've defined a textualGame() at toplevel, but this is distinct from a takeaway::textualGame() implementation - probably you just forgot the takeaway:: there.

What the error means is that the linker can't find the "vtable" for a class - every class with virtual functions has a "vtable" data structure associated with it. In GCC, this vtable is generated in the same .cpp file as the first listed non-inline member of the class; if there's no non-inline members, it will be generated wherever you instantiate the class, I believe. So you're probably failing to link the .cpp file with that first-listed non-inline member, or never defining that member in the first place.

Just add this to your recycleview in xml

 android:nestedScrollingEnabled="false"

like this

<android.support.v7.widget.RecyclerView
                    android:background="#ffffff"
                    android:id="@+id/myrecycle"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:nestedScrollingEnabled="false">

Snagged from Oracle OTN forums

Use alter table to add column, for example:

alter table tableName add(columnName NUMBER);

Then create a sequence:

CREATE SEQUENCE SEQ_ID
START WITH 1
INCREMENT BY 1
MAXVALUE 99999999
MINVALUE 1
NOCYCLE;

and, the use update to insert values in column like this

UPDATE tableName SET columnName = seq_test_id.NEXTVAL

Doing it in one bulk read:

import re

textfile = open(filename, 'r')
filetext = textfile.read()
textfile.close()
matches = re.findall("(<(\d{4,5})>)?", filetext)

Line by line:

import re

textfile = open(filename, 'r')
matches = []
reg = re.compile("(<(\d{4,5})>)?")
for line in textfile:
    matches += reg.findall(line)
textfile.close()

But again, the matches that returns will not be useful for anything except counting unless you added an offset counter:

import re

textfile = open(filename, 'r')
matches = []
offset = 0
reg = re.compile("(<(\d{4,5})>)?")
for line in textfile:
    matches += [(reg.findall(line),offset)]
    offset += len(line)
textfile.close()

But it still just makes more sense to read the whole file in at once.

See if this helps. I can set variables for Elapsed Days, Hours, Minutes, Seconds. You can format this to your liking or include in a user defined function.

Note: Don't use DateDiff(hh,@Date1,@Date2). It is not reliable! It rounds in unpredictable ways

Given two dates... (Sample Dates: two days, three hours, 10 minutes, 30 seconds difference)

declare @Date1 datetime = '2013-03-08 08:00:00'
declare @Date2 datetime = '2013-03-10 11:10:30'
declare @Days decimal
declare @Hours decimal
declare @Minutes decimal
declare @Seconds decimal

select @Days = DATEDIFF(ss,@Date1,@Date2)/60/60/24 --Days
declare @RemainderDate as datetime = @Date2 - @Days
select @Hours = datediff(ss, @Date1, @RemainderDate)/60/60 --Hours
set @RemainderDate = @RemainderDate - (@Hours/24.0)
select @Minutes = datediff(ss, @Date1, @RemainderDate)/60 --Minutes
set @RemainderDate = @RemainderDate - (@Minutes/24.0/60)
select @Seconds = DATEDIFF(SS, @Date1, @RemainderDate)    
select @Days as ElapsedDays, @Hours as ElapsedHours, @Minutes as ElapsedMinutes, @Seconds as ElapsedSeconds

char(13) is CR. For DOS-/Windows-style CRLF linebreaks, you want char(13)+char(10), like:

'This is line 1.' + CHAR(13)+CHAR(10) + 'This is line 2.'

If brew installed MySQL 5.7, the process is a bit different than for previous versions. In order to reset the root password, proceed as follows:

sudo rm -rf /usr/local/var/mysql
mysqld --initialize

A temporary password will be printed to the console and it can only be used for updating the root password:

mysql.server start
echo "ALTER USER 'root'@'localhost' IDENTIFIED BY 'my-new-password';" | mysql -uroot --password=TEMPORARY_PASSWORD

you can simply cast a string array to int array by:

var converted = arr.Select(int.Parse)

FYI, this is of little or no use to the OP but it may be of use to other readers (please do not downvote, I'm aware of this).

As a somewhat ridiculous but interesting exercise, wanted to see if I could use python functional programming to replace multiple chars. I'm pretty sure this does NOT beat just calling replace() twice. And if performance was an issue, you could easily beat this in rust, C, julia, perl, java, javascript and maybe even awk. It uses an external 'helpers' package called pytoolz, accelerated via cython (cytoolz, it's a pypi package).

from cytoolz.functoolz import compose
from cytoolz.itertoolz import chain,sliding_window
from itertools import starmap,imap,ifilter
from operator import itemgetter,contains
text='&hello#hi&yo&'
char_index_iter=compose(partial(imap, itemgetter(0)), partial(ifilter, compose(partial(contains, '#&'), itemgetter(1))), enumerate)
print '\\'.join(imap(text.__getitem__, starmap(slice, sliding_window(2, chain((0,), char_index_iter(text), (len(text),))))))

I'm not even going to explain this because no one would bother using this to accomplish multiple replace. Nevertheless, I felt somewhat accomplished in doing this and thought it might inspire other readers or win a code obfuscation contest.

As a complement to this answer, I was looking for a way to update all remote branches of my cloned repo (origin) from upstream branches in one go. This is how I did it.

This assumes you have already configured an upstream remote pointing at the source repository (where origin was forked from) and have synced it with git fetch upstream.

Then run:

for branch in $(git ls-remote --heads upstream|sed 's#^.*refs/heads/##'); do git push origin refs/remotes/upstream/$branch:refs/heads/$branch; done

The first part of this command lists all heads in the upstream remote repo and removes the SHA-1 followed by refs/heads/ branch name prefix.

Then for each of these branches, it pushes the local copy of the upstream remote tracking branch (refs/remotes/upstream/<branch> on local side) directly to the remote branch on origin (refs/heads/<branch> on remote side).

Any of these branch sync commands may fail for one of two reasons: either the upstream branch have been rewritten, or you have pushed commits on that branch to your fork. In the first case where you haven't committed anything to the branch on your fork it is safe to push forcefully (Add the -f switch; i.e. git push -f in the command above). In the other case this is normal as your fork branch have diverged and you can't expect the sync command to work until your commits have been merged back into upstream.

Try:

bash -c '[ -d my_mystery_dirname ] && run_this_command'

This will work if you can run bash on the remote machine....

In bash, [ -d something ] checks if there is directory called 'something', returning a success code if it exists and is a directory. Chaining commands with && runs the second command only if the first one succeeded. So [ -d somedir ] && command runs the command only if the directory exists.

The data from the request (content, inputs, files, querystring values) is all on this object HttpContext.Current.Request
To read the posted content

StreamReader reader = new StreamReader(HttpContext.Current.Request.InputStream);
string requestFromPost = reader.ReadToEnd();

To navigate through the all inputs

foreach (string key in HttpContext.Current.Request.Form.AllKeys)
{
   string value = HttpContext.Current.Request.Form[key];
}

Check out the documentation on boundary conditions:

http://java.sun.com/docs/books/tutorial/essential/regex/bounds.html

Check out this sample:

public static void main(final String[] args)
    {
        String x = "I found the value -12 in my string.";
        System.err.println(Arrays.toString(x.split("\\b-?\\d+\\b")));
    }

When you print it out, notice that the output is this:

[I found the value -, in my string.]

This means that the "-" character is not being picked up as being on the boundary of a word because it's not considered a word character. Looks like @brianary kinda beat me to the punch, so he gets an up-vote.

Here is my combined solution for various PHP versions.

In my company we are working with different servers with various PHP versions, so I had to find solution working for all.

$phpVersion = substr(phpversion(), 0, 3)*1;

if($phpVersion >= 5.4) {
  $encodedValue = json_encode($value, JSON_UNESCAPED_UNICODE);
} else {
  $encodedValue = preg_replace('/\\\\u([a-f0-9]{4})/e', "iconv('UCS-4LE','UTF-8',pack('V', hexdec('U$1')))", json_encode($value));
}

Credits should go to Marco Gasi & abu. The solution for PHP >= 5.4 is provided in the json_encode docs.

A trick:

Use MAMPPRO and create: server name: the EXACT adress of you website (eg: helloworld.com) to your site on your disk

On Facebook: So you can keep your original Site URL as well (eg: helloworld.com)

Now you understand that when you type your website on the adress bar you are in local! ..and when you want to be online, just inactive the server on MAMP PRO..

:)

If you want to fix vbs associations type

regsvr32 vbscript.dll
regsvr32 jscript.dll
regsvr32 wshext.dll
regsvr32 wshom.ocx
regsvr32 wshcon.dll
regsvr32 scrrun.dll

Also if you can't use vbs due to management then convert your script to a vb.net program which is designed to be easy, is easy, and takes 5 minutes.

Big difference is functions and subs are both called using brackets rather than just functions.

So the compilers are installed on all computers with .NET installed.

See this article here on how to make a .NET exe. Note the sample is for a scripting host. You can't use this, you have to put your vbs code in as .NET code.

How can I convert a VBScript to an executable (EXE) file?

<style>
.form-error {
        border: 2px solid #e74c3c;
    }
</style>



<div class="form-error">
                                {!! Form::select('color', $colors->prepend('Please Select Color', ''),           ,['class' => 'form-control dropselect form-error'
                                ,'tabindex' => $count++, 'id' => 'color']) !!}
                                </div>

The top voted solution does actually more than requested:

git checkout <sha>
git checkout -b <branch>

or

git checkout -b <branch> <sha>

move you to the new branch together with all recent changes you might have forgot to commit. This may not be your intention, especially when in the "panic mode" after losing the branch.

A cleaner (and simpler) solution seems to be the one-liner (after you found the <sha> with git reflog):

git branch <branch> <sha>

Now neither your current branch nor uncommited changes are affected. Instead only a new branch will be created all the way up to the <sha>.

If it is not the tip, it'll still work and you get a shorter branch, then you can retry with new <sha> and new branch name until you get it right.

Finally you can rename the successfully restored branch into what it was named or anything else:

git branch -m <restored branch> <final branch>

Needless to say, the key to success was to find the right commit <sha>, so name your commits wisely :)

Well, REST by design is stateless. By adding session (or anything else of that kind) you are making it stateful and defeating any purpose of having a RESTful API.

The whole idea of RESTful service is that every resource is uniquely addressable using a universal syntax for use in hypermedia links and each HTTP request should carry enough information by itself for its recipient to process it to be in complete harmony with the stateless nature of HTTP".

So whatever you are trying to do with Web API here, should most likely be re-architectured if you wish to have a RESTful API.

With that said, if you are still willing to go down that route, there is a hacky way of adding session to Web API, and it's been posted by Imran here http://forums.asp.net/t/1780385.aspx/1

Code (though I wouldn't really recommend that):

public class MyHttpControllerHandler
  : HttpControllerHandler, IRequiresSessionState
{
    public MyHttpControllerHandler(RouteData routeData): base(routeData)
    { }
}

public class MyHttpControllerRouteHandler : HttpControllerRouteHandler
{
    protected override IHttpHandler GetHttpHandler(RequestContext requestContext)
    {
        return new MyHttpControllerHandler(requestContext.RouteData);
    }
}

public class ValuesController : ApiController
{
   public string GET(string input)
   {
       var session = HttpContext.Current.Session;
       if (session != null)
       {
           if (session["Time"] == null)
           {
               session["Time"] = DateTime.Now;
           }
           return "Session Time: " + session["Time"] + input;
       }
       return "Session is not availabe" + input;
    }
}

and then add the HttpControllerHandler to your API route:

route.RouteHandler = new MyHttpControllerRouteHandler();

To avoid a panic on a zero length input, wrap the truncate operation in an if

input, _ := src.ReadString('\n')
var inputFmt string
if len(input) > 0 {
    inputFmt = input[:len(input)-1]
}
// Do something with inputFmt

JavaScript has a Number type which is a 64 bit floating point number*.

If you're looking to convert a string to a number, use

1. either parseInt or parseFloat. If using parseInt, I'd recommend always passing the radix too.
2. use the Unary + operator e.g. +"123456"
3. use the Number constructor e.g. var n = Number("12343")

*there are situations where the number will internally be held as an integer.

It's best to do this with numpy in my opinion

import numpy as np
import pandas as pd
d = pd.DataFrame(np.zeros((N_rows, N_cols)))

If you just wanted to change the example and put the table at the top, then loc='top' in the table declaration is what you need,

the_table = ax.table(cellText=cell_text,
                      rowLabels=rows,
                      rowColours=colors,
                      colLabels=columns,
                      loc='top')

Then adjusting the plot with,

plt.subplots_adjust(left=0.2, top=0.8)

A more flexible option is to put the table in its own axis using subplots,

import numpy as np
import matplotlib.pyplot as plt


fig, axs =plt.subplots(2,1)
clust_data = np.random.random((10,3))
collabel=("col 1", "col 2", "col 3")
axs[0].axis('tight')
axs[0].axis('off')
the_table = axs[0].table(cellText=clust_data,colLabels=collabel,loc='center')

axs[1].plot(clust_data[:,0],clust_data[:,1])
plt.show()

which looks like this,

You are then free to adjust the locations of the axis as required.

i wanted to return to the home screen of my android device, so i simply used :

moveTaskToBack(true);

If the page you are visiting is index.php, then your url should look like

http://localhost/test/content/home/ OR http://localhost/test/content/home/index.php

not the way you specified - http://localhost/test/content/home

To send an mms for Android 4.0 api 14 or higher without permission to write apn settings, you can use this library: Retrieve mnc and mcc codes from android, then call

Carrier c = Carrier.getCarrier(mcc, mnc);
if (c != null) {
    APN a = c.getAPN();
    if (a != null) {
        String mmsc = a.mmsc;
        String mmsproxy = a.proxy; //"" if none
        int mmsport = a.port; //0 if none
    }
}

To use this, add Jsoup and droid prism jar to the build path, and import com.droidprism.*;

round($number, -1);

This will round $number to the nearest 10. You can also pass a third variable if necessary to change the rounding mode.

More info here: http://php.net/manual/en/function.round.php

In Angular UI Bootstrap 0.13.X, tooltip-html-unsafe has been deprecated. You should now use tooltip-html and $sce.trustAsHtml() to accomplish a tooltip with html.

https://github.com/angular-ui/bootstrap/commit/e31fcf0fcb06580064d1e6375dbedb69f1c95f25

<a href="#" tooltip-html="htmlTooltip">Check me out!</a>

$scope.htmlTooltip = $sce.trustAsHtml('I\'ve been made <b>bold</b>!');

Use gist.github.com. There is a multi-language support(java, c, c++, c#, vb, haskell, ruby, javascript, lua, HTML, SQL, Tcl, Perl, JSON, groovy...)

It looks to me, like you're working in windows in which case a new line character in not simply \n but rather \r\n

You can always get the correct new line character through System.getProperty("line.separator") for example.

Finally, this is what I did:

private File getFileFromURL() {
    URL url = this.getClass().getClassLoader().getResource("/sql");
    File file = null;
    try {
        file = new File(url.toURI());
    } catch (URISyntaxException e) {
        file = new File(url.getPath());
    } finally {
        return file;
    }
}

...

File folder = getFileFromURL();
File[] listOfFiles = folder.listFiles();

Yes, and basically you can also use inline style:

<span style="font-size: 15px" class="glyphicon glyphicon-cog"></span>

My task was set to Run only when user is logged on and it was failing for me even while I was logged in and starting it manually. The user was set to me already. No password changes, etc.

I solved it by clicking "Change user" and selecting myself again.

I suspect it may have been caused by AD changing the user SID or something to that extent. Perhaps IT was doing some user management in AD, who knows.

You can use one of the following options:

{!! Html::style( asset('css/app.css')) !!}

It's easy to create this yourself

In your layout include the following ProgressBar with a specific drawable (note you should get the width from dimensions instead). The max value is important here:

<ProgressBar
    android:id="@+id/progressBar"
    style="?android:attr/progressBarStyleHorizontal"
    android:layout_width="150dp"
    android:layout_height="150dp"
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true"
    android:max="500"
    android:progress="0"
    android:progressDrawable="@drawable/circular" />

Now create the drawable in your resources with the following shape. Play with the radius (you can use innerRadius instead of innerRadiusRatio) and thickness values.

circular (Pre Lollipop OR API Level < 21)

   <shape
        android:innerRadiusRatio="2.3"
        android:shape="ring"
        android:thickness="3.8sp" >
        <solid android:color="@color/yourColor" />
   </shape>

circular ( >= Lollipop OR API Level >= 21)

    <shape
        android:useLevel="true"
        android:innerRadiusRatio="2.3"
        android:shape="ring"
        android:thickness="3.8sp" >
        <solid android:color="@color/yourColor" />
     </shape>

useLevel is "false" by default in API Level 21 (Lollipop) .

Start Animation

Next in your code use an ObjectAnimator to animate the progress field of the ProgessBar of your layout.

ProgressBar progressBar = (ProgressBar) view.findViewById(R.id.progressBar);
ObjectAnimator animation = ObjectAnimator.ofInt(progressBar, "progress", 0, 500); // see this max value coming back here, we animate towards that value
animation.setDuration(5000); // in milliseconds
animation.setInterpolator(new DecelerateInterpolator());
animation.start();

Stop Animation

progressBar.clearAnimation();

P.S. unlike examples above, it give smooth animation.

I use lists to filter dataframes by whether or not they have a value %in% a list.

I had been manually creating lists by exporting a 1 column dataframe to Excel where I would add " ", around each element, before pasting into R: list <- c("el1", "el2", ...) which was usually followed by FilteredData <- subset(Data, Column %in% list).

After searching stackoverflow and not finding an intuitive way to convert a 1 column dataframe into a list, I am now posting my first ever stackoverflow contribution:

# assuming you have a 1 column dataframe called "df"
list <- c()
for(i in 1:nrow(df)){
  list <- append(list, df[i,1])
}
View(list)
# This list is not a dataframe, it is a list of values
# You can filter a dataframe using "subset([Data], [Column] %in% list")

The library I've used is ini4j. It is lightweight and parses the ini files with ease. Also it uses no esoteric dependencies to 10,000 other jar files, as one of the design goals was to use only the standard Java API

This is an example on how the library is used:

Ini ini = new Ini(new File(filename));
java.util.prefs.Preferences prefs = new IniPreferences(ini);
System.out.println("grumpy/homePage: " + prefs.node("grumpy").get("homePage", null));

Adding a bit more to above-mentioned answers.

id of a variable changes upon reassignment.

>>> a = 'initial_string'
>>> id(a)
139982120425648
>>> a = 'new_string'
>>> id(a)
139982120425776

Which means that we have mutated the variable a to point to a new string. Now there exist two string(str) objects:

'initial_string' with id = 139982120425648

and

'new_string' with id = 139982120425776

Consider the below code:

>>> b = 'intitial_string'
>>> id(b)
139982120425648

Now, b points to the 'initial_string' and has the same id as a had before reassignment.

Thus, the 'intial_string' has not been mutated.

You can use the @helper Razor directive:

@helper WelcomeMessage(string username)
{
    <p>Welcome, @username.</p>
}

Then you invoke it like this:

@WelcomeMessage("John Smith")

I am developing a motion-detection and shake-detection app for my university project.

Besides the original target of the application, I am splitting the library part (responsible for motion and shake detection) from the app. The code is free, available on SourceForge with the project name "BenderCatch". Documentation I am producing will be ready around mid-september. http://sf.net/projects/bendercatch

It uses a more precise way to detect shake: watches BOTH the difference of force between SensorEvents AND the oscillations present in X and Y axis when you perform a shake. It can even make a sound (or vibrate) on each oscillation of the shake.

Feel free to ask me more by e-mail at raffaele [at] terzigno [dot] com

If you already have Java Development Kit on your PC and the bin directory is in your path (in most cases), you can use the command line:

jar xf test.zip

or if not in your path:

C:\Java\jdk1.6.0_03\bin>jar xf test.zip

Complete set of options for the jar tool available here.

Examples:

Extract jar file
    jar x[v]f jarfile [inputfiles] [-Joption] 
    jar x[v] [inputfiles] [-Joption]

try with:

tr:last-child td:last-child{
    border:none;
    /*any other style*/
}

this will only affect the very last td element in the table, assuming is the only one (else, you'll just have to identify your table). Though, is very general, and it will adapt to the last TD if you add more content to your table. So if it is a particular case

td:nth-child(5){
    border:none;
}

should be enough.

Scope in python follows this order:

• Search the local scope

• Search the scope of any enclosing functions

• Search the global scope

• Search the built-ins

(source)

Notice that if and other looping/branching constructs are not listed - only classes, functions, and modules provide scope in Python, so anything declared in an if block has the same scope as anything decleared outside the block. Variables aren't checked at compile time, which is why other languages throw an exception. In python, so long as the variable exists at the time you require it, no exception will be thrown.

T and TRUE are True, F and FALSE are False. T and F can be redefined, however, so you should only rely upon TRUE and FALSE. If you compare 0 to FALSE and 1 to TRUE, you will find that they are equal as well, so you might consider them to be True and False as well.

As an alternative you can also query the information_schema database and retrieve the data from the global_variables (and global_status of course too). This approach provides the same information, but gives you the opportunity to do more with the results, as it is a plain old query.

For example you can convert units to become more readable. The following query provides the current global setting for the innodb_log_buffer_size in bytes and megabytes:

SELECT
  variable_name,
  variable_value AS innodb_log_buffer_size_bytes,
  ROUND(variable_value / (1024*1024)) AS innodb_log_buffer_size_mb
FROM information_schema.global_variables
WHERE variable_name LIKE  'innodb_log_buffer_size';

As a result you get:

+------------------------+------------------------------+---------------------------+

Just in case anyone else ends up here from a web search, and has Grunt already in their dependency list, the answer to this becomes trivial. Here's my solution:

/**
 * Return all the subfolders of this path
 * @param {String} parentFolderPath - valid folder path
 * @param {String} glob ['/*'] - optional glob so you can do recursive if you want
 * @returns {String[]} subfolder paths
 */
getSubfolders = (parentFolderPath, glob = '/*') => {
    return grunt.file.expand({filter: 'isDirectory'}, parentFolderPath + glob);
}

WARNING: This deletes all commits on the email branch. It's like deleting the email branch and creating it anew at the head of the staging branch.

The easiest way to do it:

//the branch you want to overwrite
git checkout email 

//reset to the new branch
git reset --hard origin/staging

// push to remote
git push -f

Now the email branch and the staging are the same.

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

How are you adding your Weblogic classes to the classpath in Eclipse? Are you using WTP, and a server runtime? If so, is your server runtime associated with your project?

If you right click on your project and choose build path->configure build path and then choose the libraries tab. You should see the weblogic libraries associated here. If you do not you can click Add Library->Server Runtime. If the library is not there, then you first need to configure it. Windows->Preferences->Server->Installed runtimes

The answer of Fabio is really good but it take a long execution time (as Trilarion already has written)

I have an other solution with faster execution.

START TRANSACTION;
set @N := (now());
INSERT INTO table2 select * from table1 where ts < date_sub(@N,INTERVAL 32 DAY);
DELETE FROM table1 WHERE ts < date_sub(@N,INTERVAL 32 DAY);
COMMIT;

@N gets the Timestamp at the begin and is used for both commands. All is in a Transaction to be sure nobody is disturbing

I think you've actually got a wider confusion here.

The initial error is that you're trying to call split on the whole list of lines, and you can't split a list of strings, only a string. So, you need to split each line, not the whole thing.

And then you're doing for points in Type, and expecting each such points to give you a new x and y. But that isn't going to happen. Types is just two values, x and y, so first points will be x, and then points will be y, and then you'll be done. So, again, you need to loop over each line and get the x and y values from each line, not loop over a single Types from a single line.

So, everything has to go inside a loop over every line in the file, and do the split into x and y once for each line. Like this:

def getQuakeData():
    filename = input("Please enter the quake file: ")
    readfile = open(filename, "r")

    for line in readfile:
        Type = line.split(",")
        x = Type[1]
        y = Type[2]
        print(x,y)

getQuakeData()

As a side note, you really should close the file, ideally with a with statement, but I'll get to that at the end.

Interestingly, the problem here isn't that you're being too much of a newbie, but that you're trying to solve the problem in the same abstract way an expert would, and just don't know the details yet. This is completely doable; you just have to be explicit about mapping the functionality, rather than just doing it implicitly. Something like this:

def getQuakeData():
    filename = input("Please enter the quake file: ")
    readfile = open(filename, "r")
    readlines = readfile.readlines()
    Types = [line.split(",") for line in readlines]
    xs = [Type[1] for Type in Types]
    ys = [Type[2] for Type in Types]
    for x, y in zip(xs, ys):
        print(x,y)

getQuakeData()

Or, a better way to write that might be:

def getQuakeData():
    filename = input("Please enter the quake file: ")
    # Use with to make sure the file gets closed
    with open(filename, "r") as readfile:
        # no need for readlines; the file is already an iterable of lines
        # also, using generator expressions means no extra copies
        types = (line.split(",") for line in readfile)
        # iterate tuples, instead of two separate iterables, so no need for zip
        xys = ((type[1], type[2]) for type in types)
        for x, y in xys:
            print(x,y)

getQuakeData()

Finally, you may want to take a look at NumPy and Pandas, libraries which do give you a way to implicitly map functionality over a whole array or frame of data almost the same way you were trying to.

I think these kinds of problems are solved if we think about real life.

Bad Practice:

Example 1:

Darling everything is FINE/OK (HTTP CODE 200) - (Success):
{
  ...but I don't want us to be together anymore!!!... (Error)
  // Then everything isn't OK???
}

Example 2:

You are the best employee (HTTP CODE 200) - (Success):
{
  ...But we cannot continue your contract!!!... (Error)
  // Then everything isn't OK???
}

Good Practices:

 Darling I don't feel good (HTTP CODE 400) - (Error):
{
  ...I no longer feel anything for you, I think the best thing is to separate... (Error)
  // In this case, you are alerting me from the beginning that something is wrong ...
}

This is only my personal opinion, each one can implement it as it is most comfortable or needs.

Note: The idea for this explanation was drawn from a great friend @diosney

I'm using a message service that wraps an rxjs Subject (TypeScript)

Plunker example: Message Service

import { Injectable } from '@angular/core';
import { Subject } from 'rxjs/Subject';
import { Subscription } from 'rxjs/Subscription';
import 'rxjs/add/operator/filter'
import 'rxjs/add/operator/map'

interface Message {
  type: string;
  payload: any;
}

type MessageCallback = (payload: any) => void;

@Injectable()
export class MessageService {
  private handler = new Subject<Message>();

  broadcast(type: string, payload: any) {
    this.handler.next({ type, payload });
  }

  subscribe(type: string, callback: MessageCallback): Subscription {
    return this.handler
      .filter(message => message.type === type)
      .map(message => message.payload)
      .subscribe(callback);
  }
}

Components can subscribe and broadcast events (sender):

import { Component, OnDestroy } from '@angular/core'
import { MessageService } from './message.service'
import { Subscription } from 'rxjs/Subscription'

@Component({
  selector: 'sender',
  template: ...
})
export class SenderComponent implements OnDestroy {
  private subscription: Subscription;
  private messages = [];
  private messageNum = 0;
  private name = 'sender'

  constructor(private messageService: MessageService) {
    this.subscription = messageService.subscribe(this.name, (payload) => {
      this.messages.push(payload);
    });
  }

  send() {
    let payload = {
      text: `Message ${++this.messageNum}`,
      respondEvent: this.name
    }
    this.messageService.broadcast('receiver', payload);
  }

  clear() {
    this.messages = [];
  }

  ngOnDestroy() {
    this.subscription.unsubscribe();
  }
}

(receiver)

import { Component, OnDestroy } from '@angular/core'
import { MessageService } from './message.service'
import { Subscription } from 'rxjs/Subscription'

@Component({
  selector: 'receiver',
  template: ...
})
export class ReceiverComponent implements OnDestroy {
  private subscription: Subscription;
  private messages = [];

  constructor(private messageService: MessageService) {
    this.subscription = messageService.subscribe('receiver', (payload) => {
      this.messages.push(payload);
    });
  }

  send(message: {text: string, respondEvent: string}) {
    this.messageService.broadcast(message.respondEvent, message.text);
  }

  clear() {
    this.messages = [];
  }

  ngOnDestroy() {
    this.subscription.unsubscribe();
  }
}

The subscribe method of MessageService returns an rxjs Subscription object, which can be unsubscribed from like so:

import { Subscription } from 'rxjs/Subscription';
...
export class SomeListener {
  subscription: Subscription;

  constructor(private messageService: MessageService) {
    this.subscription = messageService.subscribe('someMessage', (payload) => {
      console.log(payload);
      this.subscription.unsubscribe();
    });
  }
}

Also see this answer: https://stackoverflow.com/a/36782616/1861779

The CloseReason enumeration you found on MSDN is just for the purpose of checking whether the user closed the app, or it was due to a shutdown, or closed by the task manager, etc...

You can do different actions, according to the reason, like:

void Form_FormClosing(object sender, FormClosingEventArgs e)
{
    if(e.CloseReason == CloseReason.UserClosing)
        // Prompt user to save his data

    if(e.CloseReason == CloseReason.WindowsShutDown)
        // Autosave and clear up ressources
}

But like you guessed, there is no difference between clicking the x button, or rightclicking the taskbar and clicking 'close', or pressing Alt F4, etc. It all ends up in a CloseReason.UserClosing reason.

When I tried to select the development provisioning profile in Code Signing Identity is would say "profile doesn't match any valid certificate". So when I followed the two step process below it worked:

1) Under "Code Signing Identity" for Development change to "Don't Code Sign".
2) Then Under "Code Signing Identity" for Development you will be able to select your provisioning profile for Development.

Drove me nuts, but stumbled upon the solution.

Given:

A_1 = [10 200 7 150]';
A_2 = [0.001 0.450 0.007 0.200]';

(As others have already pointed out) There are tools to simply compute correlation, most obviously corr:

corr(A_1, A_2);  %Returns 0.956766573975184  (Requires stats toolbox)

You can also use base Matlab's corrcoef function, like this:

M = corrcoef([A_1 A_2]):  %Returns [1 0.956766573975185; 0.956766573975185 1];
M(2,1);  %Returns 0.956766573975184 

Which is closely related to the cov function:

cov([condition(A_1) condition(A_2)]);

As you almost get to in your original question, you can scale and adjust the vectors yourself if you want, which gives a slightly better understanding of what is going on. First create a condition function which subtracts the mean, and divides by the standard deviation:

condition = @(x) (x-mean(x))./std(x);  %Function to subtract mean AND normalize standard deviation

Then the correlation appears to be (A_1 * A_2)/(A_1^2), like this:

(condition(A_1)' * condition(A_2)) / sum(condition(A_1).^2);  %Returns 0.956766573975185

By symmetry, this should also work

(condition(A_1)' * condition(A_2)) / sum(condition(A_2).^2); %Returns 0.956766573975185

And it does.

I believe, but don't have the energy to confirm right now, that the same math can be used to compute correlation and cross correlation terms when dealing with multi-dimensiotnal inputs, so long as care is taken when handling the dimensions and orientations of the input arrays.

Actually, the problem here is the use of ReadContentAsObject. Unfortunately, this method does not live up to its expectations; while it should detect the most appropirate type for the value, it actually returns a string, no matter what(this can be verified using Reflector).

However, in your specific case, you already know the type you want to cast to, therefore i would say you are using the wrong method.

Try using ReadContentAs instead, it's exactly what you need.

private static T ReadData<T>(XmlReader reader, string value)
{
    reader.MoveToAttribute(value);
    object readData = reader.ReadContentAs(typeof(T), null);
    return (T)readData;
}

no real explanation is given by Java (in either JavaDoc or much coveted code comments), but looking at the code, it seems that this is magic:

calling stack:

String.indexOf(char[], int, int, char[], int, int, int) line: 1591  
String.indexOf(String, int) line: 1564  
String.indexOf(String) line: 1546   
String.contains(CharSequence) line: 1934    

code:

/**
 * Code shared by String and StringBuffer to do searches. The
 * source is the character array being searched, and the target
 * is the string being searched for.
 *
 * @param   source       the characters being searched.
 * @param   sourceOffset offset of the source string.
 * @param   sourceCount  count of the source string.
 * @param   target       the characters being searched for.
 * @param   targetOffset offset of the target string.
 * @param   targetCount  count of the target string.
 * @param   fromIndex    the index to begin searching from.
 */
static int indexOf(char[] source, int sourceOffset, int sourceCount,
                   char[] target, int targetOffset, int targetCount,
                   int fromIndex) {
  if (fromIndex >= sourceCount) {
        return (targetCount == 0 ? sourceCount : -1);
  }
      if (fromIndex < 0) {
        fromIndex = 0;
      }
  if (targetCount == 0) {//my comment: this is where it returns, the size of the 
    return fromIndex;    // incoming string is 0,  which is passed in as targetCount
  }                      // fromIndex is 0 as well, as the search starts from the 
                         // start of the source string
    ...//the rest of the method 

Struggled with this a while and thought I'd post on this question as it's the first search result. Adding the encoding="iso-8859-1" tag to pandas read_csv didn't work, nor did any other encoding, kept giving a UnicodeDecodeError.

If you're passing a file handle to pd.read_csv(), you need to put the encoding attribute on the file open, not in read_csv. Obvious in hindsight, but a subtle error to track down.

You can do this the following two ways:

1) Using loop attribute in video element (mentioned in the first answer):

2) and you can use the ended media event:

window.addEventListener('load', function(){
    var newVideo = document.getElementById('videoElementId');
    newVideo.addEventListener('ended', function() {
        this.currentTime = 0;
        this.play();
    }, false);

    newVideo.play();

});

if you want to "clean" the new lines, flamebaud comment using regex @"[\r\n]+" is the best choice.

using System;
using System.Text.RegularExpressions;

class MainClass {
  public static void Main (string[] args) {
    string str = "AAA\r\nBBB\r\n\r\n\r\nCCC\r\r\rDDD\n\n\nEEE";

    Console.WriteLine (str.Replace(System.Environment.NewLine, "-"));
    /* Result:
    AAA
    -BBB
    -
    -
    -CCC


    DDD---EEE
    */
    Console.WriteLine (Regex.Replace(str, @"\r\n?|\n", "-"));
    // Result:
    // AAA-BBB---CCC---DDD---EEE

    Console.WriteLine (Regex.Replace(str, @"[\r\n]+", "-"));
    // Result:
    // AAA-BBB-CCC-DDD-EEE
  }
}

For MySQL or PostgreSQL 9.3+, a better way is to use the LEAST and GREATEST functions.

SELECT GREATEST(A.date0, B.date0) AS date0, 
       LEAST(A.date1, B.date1, B.date2) AS date1
FROM A, B
WHERE B.x = A.x

With:

• GREATEST(value [, ...]) : Returns the largest (maximum-valued) argument from values provided
• LEAST(value [, ...]) Returns the smallest (minimum-valued) argument from values provided

• MySQL http://dev.mysql.com/doc/refman/5.0/en/comparison-operators.html
• Postgres https://www.postgresql.org/docs/current/functions-conditional.html

Based on Tim Down's answer, but it checks for the last known "good" text row. It places the cursor at the very end.

Furthermore, I could also recursively/iteratively check the last child of each consecutive last child to find the absolute last "good" text node in the DOM.

function onClickHandler() {_x000D_
  setCaret(document.getElementById("editable"));_x000D_
}_x000D_

    }_x000D_

Note that you can use the Polynomial class directly to do the fitting and return a Polynomial instance.

from numpy.polynomial import Polynomial

p = Polynomial.fit(x, y, 4)
plt.plot(*p.linspace())

p uses scaled and shifted x values for numerical stability. If you need the usual form of the coefficients, you will need to follow with

pnormal = p.convert(domain=(-1, 1))

Simply use :

mapA.equals(mapB);

Compares the specified object with this map for equality. Returns true if the given object is also a map and the two maps represent the same mappings

The SQL standard way to implement recursive queries, as implemented e.g. by IBM DB2 and SQL Server, is the WITH clause. See this article for one example of translating a CONNECT BY into a WITH (technically a recursive CTE) -- the example is for DB2 but I believe it will work on SQL Server as well.

Edit: apparently the original querant requires a specific example, here's one from the IBM site whose URL I already gave. Given a table:

CREATE TABLE emp(empid  INTEGER NOT NULL PRIMARY KEY,
                 name   VARCHAR(10),
                 salary DECIMAL(9, 2),
                 mgrid  INTEGER);

where mgrid references an employee's manager's empid, the task is, get the names of everybody who reports directly or indirectly to Joan. In Oracle, that's a simple CONNECT:

SELECT name 
  FROM emp
  START WITH name = 'Joan'
  CONNECT BY PRIOR empid = mgrid

In SQL Server, IBM DB2, or PostgreSQL 8.4 (as well as in the SQL standard, for what that's worth;-), the perfectly equivalent solution is instead a recursive query (more complex syntax, but, actually, even more power and flexibility):

WITH n(empid, name) AS 
   (SELECT empid, name 
    FROM emp
    WHERE name = 'Joan'
        UNION ALL
    SELECT nplus1.empid, nplus1.name 
    FROM emp as nplus1, n
    WHERE n.empid = nplus1.mgrid)
SELECT name FROM n

Oracle's START WITH clause becomes the first nested SELECT, the base case of the recursion, to be UNIONed with the recursive part which is just another SELECT.

SQL Server's specific flavor of WITH is of course documented on MSDN, which also gives guidelines and limitations for using this keyword, as well as several examples.

The main difference is an abstract class can contain default implementation whereas an interface cannot.

An interface is a contract of behaviour without any implementation.

The following adds elements to a list in a loop.

l<-c()
i=1

while(i<100) {

    b<-i
    l<-c(l,b)
    i=i+1
}

Late in here, but in case someone comes here from google---

Go to the location of your .py file. Press SHIFT then right click anywhere and choose open command prompt from here. Once it's up, Just add

"python NameOfTheProg.py" to the cmd line

Visual Basic, C#, and C++ all have syntax for accessing the Item property without using its name. Instead, the variable containing the List is used as if it were an array.

List[index]

See for instance: https://msdn.microsoft.com/en-us/library/0ebtbkkc(v=vs.110).aspx

These answers are much too complicated.

A simpler way to do this without creating two arcs or convert to different coordinate systems..

This assumes your canvas area has width w and height h.

`M${w*0.5 + radius},${h*0.5}
 A${radius} ${radius} 0 1 0 ${w*0.5 + radius} ${h*0.5001}`

Just use the "long arc" flag, so the full flag is filled. Then make the arcs 99.9999% the full circle. Visually it is the same. Avoid the sweep flag by just starting the circle at the rightmost point in the circle (one radius directly horizontal from the center).

If you need exactly m rows, realistically you'll generate your subset of IDs outside of SQL. Most methods require at some point to select the "nth" entry, and SQL tables are really not arrays at all. The assumption that the keys are consecutive in order to just join random ints between 1 and the count is also difficult to satisfy — MySQL for example doesn't support it natively, and the lock conditions are... tricky.

Here's an O(max(n, m lg n))-time, O(n)-space solution assuming just plain BTREE keys:

1. Fetch all values of the key column of the data table in any order into an array in your favorite scripting language in O(n)
2. Perform a Fisher-Yates shuffle, stopping after m swaps, and extract the subarray [0:m-1] in ?(m)
3. "Join" the subarray with the original dataset (e.g. SELECT ... WHERE id IN (<subarray>)) in O(m lg n)

Any method that generates the random subset outside of SQL must have at least this complexity. The join can't be any faster than O(m lg n) with BTREE (so O(m) claims are fantasy for most engines) and the shuffle is bounded below n and m lg n and doesn't affect the asymptotic behavior.

In Pythonic pseudocode:

ids = sql.query('SELECT id FROM t')
for i in range(m):
  r = int(random() * (len(ids) - i))
  ids[i], ids[i + r] = ids[i + r], ids[i]

results = sql.query('SELECT * FROM t WHERE id IN (%s)' % ', '.join(ids[0:m-1])

PLEASE NOTE! If you have gone through all of the above, like "I" did, and still get the Orange icon, and, when you test Port 80 you get "Apache", look at the file: c:/wamp/bin/apache/apache2.4.9/conf/httpd.conf (your apache version number may differ).

In the file, about line # 62, you'll find a note saying to fill in this:

Listen 0.0.0.0:80 Listen [::0]:80

Why?

Change this to Listen on specific IP addresses as shown below to prevent Apache from glomming onto all bound IP addresses.

I changed that to match my localhost IP address and when I restarted Wamp, it quickly went from Red to Green. Success!...3 hours later....

            var date = new DateTime(dateNow.Year, dateNow.Month, dateNow.Day,
                       int.Parse(timeParts[0]), int.Parse(timeParts[1]), int.Parse(timeParts[2]));
            TimeSpan ts;
            if (date > dateNow)
                ts = date - dateNow;
            else
            {
                date = date.AddDays(1);
                ts = date - dateNow;
            }

            //waits certan time and run the code
            Task.Delay(ts).ContinueWith((x) => OnTimer());

public void OnTimer()
    {
        ViewBag.ErrorMessage = "EROOROOROROOROR";
    }

The aim of having the kernel support different ones is that you can try them out without a reboot; you can then run test workloads through the sytsem, measure performance, and then make that the standard one for your app.

On modern server-grade hardware, only the noop one appears to be at all useful. The others seem slower in my tests.

This also works....sometimes you may want to construct the definition of the parameters outside of the actual EXEC call.

DECLARE @Parmdef nvarchar (500)
DECLARE @SQL nvarchar (max)
DECLARE @xTxt1  nvarchar (100) = 'test1'
DECLARE @xTxt2  nvarchar (500) = 'test2' 
SET @parmdef = '@text1 nvarchar (100), @text2 nvarchar (500)'
SET @SQL = 'PRINT @text1 + '' '' + @text2'
EXEC sp_executeSQL @SQL, @Parmdef, @xTxt1, @xTxt2

you should never do so... and I think trying it in latest browsers is useless(from what I know)... all latest browsers on the other hand, will not allow this...

some other links that you can go through, to find a workaround like getting the value serverside, but not in clientside(javascript)

Yes, we can run docker in docker, we'll need to attach the unix sockeet "/var/run/docker.sock" on which the docker daemon listens by default as volume to the parent docker using "-v /var/run/docker.sock:/var/run/docker.sock". Sometimes, permissions issues may arise for docker daemon socket for which you can write "sudo chmod 757 /var/run/docker.sock".

And also it would require to run the docker in privileged mode, so the commands would be:

There is indeed a big difference, which you should keep in mind. setScale really set the scale of your number whereas round does round your number to the specified digits BUT it "starts from the leftmost digit of exact result" as mentioned within the jdk. So regarding your sample the results are the same, but try 0.0034 instead. Here's my note about that on my blog:

http://araklefeistel.blogspot.com/2011/06/javamathbigdecimal-difference-between.html

There are some workarounds to make it possible:

1. Recreating the whole table

2. Create new columns within the current table

3. Create a view

What personally me fount usable for me is:

(mousedown)="callEvent()" (keyup.enter)="$event.preventDefault()

keyup.enter prevents the event from triggering on keyup, but it still occurs for keydown, that works for me.

I faced a similar issue during work with Ubuntu 16.04 by using Docker. In my case that was a problem with Composer, but error message (and thus the problem) was the same.

Because of minimalist Docker-oriented base image I had missing ca-certificates package and simple apt-get install ca-certificates helped me.

NOTE: it does not take subList implementation into account.

import java.util.ArrayList;
import java.util.Collection;
import java.util.HashSet;
import java.util.Set;

public class UniqueList<T> extends ArrayList<T> {

    private static final long serialVersionUID = 1L;

    /** Unique elements SET */
    private final Set<T> set=new HashSet();

    /** Used by addAll methods */
    private Collection<T> addUnique(Collection<? extends T> col) {
        Collection<T> unique=new ArrayList();
        for(T e: col){
            if (set.add(e)) unique.add(e);
        }
        return unique;
    }

    @Override
    public boolean add(T e) {
        return set.add(e) ? super.add(e) : false;
    }

    @Override
    public boolean addAll(Collection<? extends T> col) {
        return super.addAll(addUnique(col));
    }

    @Override
    public void add(int index, T e) {
        if (set.add(e)) super.add(index, e);
    }

    @Override
    public boolean addAll(int index, Collection<? extends T> col) {
        return super.addAll(index, addUnique(col));
    }

}

if you are a exists project, maybe should execute npm install.

guntjs getting started step 2.

Maybe I'll help someone else. None of the above answers worked for Catalina. Finally, this solved the problem

echo 'export PATH="/usr/local/opt/[email protected]/bin:$PATH"' >> /Users/$(whoami)/.bash_profile

Of course, you have to change for the version of mysql you have installed

Pass it a Comparator. Fill in your desired type in place of T

Using lambdas (Java 8+):

int initialCapacity = 10;
PriorityQueue<T> pq = new PriorityQueue<>(initialCapacity, (e1, e2) -> { return e1.compareTo(e2); });

Classic way, using anonymous class:

int initialCapacity = 10;
PriorityQueue<T> pq = new PriorityQueue<>(initialCapacity, new Comparator<T> () {

    @Override
    public int compare(T e1, T e2) {
        return e1.compareTo(e2);
    }

});

To sort in reverse order, simply swap e1, e2.

Here is solution ( ref : https://www.cluemediator.com/object-doesnt-support-property-or-method-includes-in-ie )

if (!Array.prototype.includes) {
  Object.defineProperty(Array.prototype, 'includes', {
    value: function (searchElement, fromIndex) {

      if (this == null) {
        throw new TypeError('"this" is null or not defined');
      }

      // 1. Let O be ? ToObject(this value).
      var o = Object(this);

      // 2. Let len be ? ToLength(? Get(O, "length")).
      var len = o.length >>> 0;

      // 3. If len is 0, return false.
      if (len === 0) {
        return false;
      }

      // 4. Let n be ? ToInteger(fromIndex).
      //    (If fromIndex is undefined, this step produces the value 0.)
      var n = fromIndex | 0;

      // 5. If n = 0, then
      //  a. Let k be n.
      // 6. Else n < 0,
      //  a. Let k be len + n.
      //  b. If k < 0, let k be 0.
      var k = Math.max(n >= 0 ? n : len - Math.abs(n), 0);

      function sameValueZero(x, y) {
        return x === y || (typeof x === 'number' && typeof y === 'number' && isNaN(x) && isNaN(y));
      }

      // 7. Repeat, while k < len
      while (k < len) {
        // a. Let elementK be the result of ? Get(O, ! ToString(k)).
        // b. If SameValueZero(searchElement, elementK) is true, return true.
        if (sameValueZero(o[k], searchElement)) {
          return true;
        }
        // c. Increase k by 1. 
        k++;
      }

      // 8. Return false
      return false;
    }
  });
}

Just use a specific variable for that.

$ cat Makefile 
all:
    echo foo | gcc $(USER_DEFINES) -E -xc - 

$ make USER_DEFINES="-Dfoo=one"
echo foo | gcc -Dfoo=one -E -xc - 
...
one

$ make USER_DEFINES="-Dfoo=bar"
echo foo | gcc -Dfoo=bar -E -xc - 
...
bar

$ make 
echo foo | gcc  -E -xc - 
...
foo

Use Python 2.7, is has more 3rd party libs at the moment. (Edit: see below).

I recommend you using the stdlib module urllib2, it will allow you to comfortably get web resources. Example:

import urllib2

response = urllib2.urlopen("http://google.de")
page_source = response.read()

For parsing the code, have a look at BeautifulSoup.

BTW: what exactly do you want to do:

Just for background, I need to download a page and replace any img with ones I have

Edit: It's 2014 now, most of the important libraries have been ported, and you should definitely use Python 3 if you can. python-requests is a very nice high-level library which is easier to use than urllib2.

On a mac with OSX 10.10.5,Android Studio and SDK installed the path is

/Users/mles/Library/Android/sdk/build-tools/23.0.1/zipalign

 $('image').animate({ 'zoom': 1}, 400);

(And if you have no admin access to the server)

ALTER ROLE <your_login_role> SET search_path TO a,b,c;

Two important things to know about:

1. When a schema name is not simple, it needs to be wrapped in double quotes.
2. The order in which you set default schemas a, b, c matters, as it is also the order in which the schemas will be looked up for tables. So if you have the same table name in more than one schema among the defaults, there will be no ambiguity, the server will always use the table from the first schema you specified for your search_path.

This issue is still present in Mac Office 2011 and Office 2013, I cannot prevent it happening. It seems such a basic thing.

In my case I had values such as "1 - 2" & "7 - 12" within the CSV enclosed correctly within inverted commas, this automatically converts to a date within excel, if you try subsequently convert it to just plain text you would get a number representation of the date such as 43768. Additionally it reformats large numbers found in barcodes and EAN numbers to 123E+ numbers again which cannot be converted back.

I have found that Google Drive's Google Sheets doesnt convert the numbers to dates. The barcodes do have commas in them every 3 characters but these are easily removed. It handles CSVs really well especially when dealing with MAC / Windows CSVs.

Might save someone sometime.
