CSS rules are inherited by default - hence the "cascading" name. To get what you want you need to use !important:

form div
{
    font-size: 12px;
    font-weight: bold;
}

div.content
{
    // any rule you want here, followed by !important
}

We have been using jqGrid on a project and have had some good luck with it. Lots of options for inline editing, etc. If that stuff isn't necessary, then we've just used a plain foreach loop like @Hrvoje.

You can directly set the content type like below:

res.writeHead(200, {'Content-Type': 'text/plain'});

For reference go through the nodejs Docs link.

But if you really want to add some animation while scrolling, you can try my simple plugin (AnimateScroll) which currently supports more than 30 easing styles

Another way similar to the yglodt's

In application.properties:

spring.jpa.properties.hibernate.current_session_context_class=org.springframework.orm.hibernate4.SpringSessionContext

And in your configuration class:

@Bean
public SessionFactory sessionFactory(HibernateEntityManagerFactory hemf) {
    return hemf.getSessionFactory();
}

Then you can autowire the SessionFactory in your services as usual:

@Autowired
private SessionFactory sessionFactory;

I find the following most elegant:

b = np.insert(a, 3, values=0, axis=1) # Insert values before column 3

An advantage of insert is that it also allows you to insert columns (or rows) at other places inside the array. Also instead of inserting a single value you can easily insert a whole vector, for instance duplicate the last column:

b = np.insert(a, insert_index, values=a[:,2], axis=1)

Which leads to:

array([[1, 2, 3, 3],
       [2, 3, 4, 4]])

For the timing, insert might be slower than JoshAdel's solution:

In [1]: N = 10

In [2]: a = np.random.rand(N,N)

In [3]: %timeit b = np.hstack((a, np.zeros((a.shape[0], 1))))
100000 loops, best of 3: 7.5 µs per loop

In [4]: %timeit b = np.zeros((a.shape[0], a.shape[1]+1)); b[:,:-1] = a
100000 loops, best of 3: 2.17 µs per loop

In [5]: %timeit b = np.insert(a, 3, values=0, axis=1)
100000 loops, best of 3: 10.2 µs per loop

copy() only works with files.

Both the DOS copy and Unix cp commands will copy recursively - so the quickest solution is just to shell out and use these. e.g.

`cp -r $src $dest`;

Otherwise you'll need to use the opendir/readdir or scandir to read the contents of the directory, iterate through the results and if is_dir returns true for each one, recurse into it.

e.g.

function xcopy($src, $dest) {
    foreach (scandir($src) as $file) {
        if (!is_readable($src . '/' . $file)) continue;
        if (is_dir($src .'/' . $file) && ($file != '.') && ($file != '..') ) {
            mkdir($dest . '/' . $file);
            xcopy($src . '/' . $file, $dest . '/' . $file);
        } else {
            copy($src . '/' . $file, $dest . '/' . $file);
        }
    }
}

try this

   <input type="button" style="background-image:url('your_url')"/>

Another way, which is a little bit easier for me is to use named pipes. Named pipes provided a way to synchronize and sending messages between different processes.

A.bash:

#!/bin/bash
msg="The Message"
echo $msg > A.pipe

B.bash:

#!/bin/bash
msg=`cat ./A.pipe`
echo "message from A : $msg"

Usage:

$ mkfifo A.pipe #You have to create it once
$ ./A.bash & ./B.bash # you have to run your scripts at the same time

B.bash will wait for message and as soon as A.bash sends the message, B.bash will continue its work.

With Pathlib from python3 standard library:

Path(mypath).mkdir(parents=True, exist_ok=True)

If parents is true, any missing parents of this path are created as needed; they are created with the default permissions without taking mode into account (mimicking the POSIX mkdir -p command). If exist_ok is false (the default), an FileExistsError is raised if the target directory already exists.

If exist_ok is true, FileExistsError exceptions will be ignored (same behavior as the POSIX mkdir -p command), but only if the last path component is not an existing non-directory file.

Changed in version 3.5: The exist_ok parameter was added.

The answers using subclasses or categories to allow VCs within UINavigationController and UITabBarController classes work well. Launching a portrait-only modal from a landscape tab bar controller failed. If you need to do this, then use the trick of displaying and hiding a non-animated modal view, but do it in the viewDidAppear method. It didn't work for me in viewDidLoad or viewWillAppear.

Apart from that, the solutions above work fine.

I was/am in the same boat as you for different reasons (partly educational, partly constraints). I had to re-write all the containers of the standard library and the containers had to conform to the standard. That means, if I swap out my container with the stl version, the code would work the same. Which also meant that I had to re-write the iterators.

Anyway, I looked at EASTL. Apart from learning a ton about containers that I never learned all this time using the stl containers or through my undergraduate courses. The main reason is that EASTL is more readable than the stl counterpart (I found this is simply because of the lack of all the macros and straight forward coding style). There are some icky things in there (like #ifdefs for exceptions) but nothing to overwhelm you.

As others mentioned, look at cplusplus.com's reference on iterators and containers.

Here is an example how to do it for LENOVA or similar PC:

1. Start the machine.
2. Press F2 to enter BIOS.
3. Security-> System Security
4. Enable Virtualization Technology (VTx) and Virtualization Technology Directed I/O (VTd).
5. Save and restart the machine

If you use androidx.appcompat:appcompat and want a custom drawable (of type selector with android:state_checked) to work on old platform versions in addition to new platform versions, you need to use

    <CheckBox
        app:buttonCompat="@drawable/..."

instead of

    <CheckBox
        android:button="@drawable/..."

The following function finds all the occurrences of a string inside another while informing the position where each occurrence is found.

You can call the function using the test cases in the table below. You can try with words, spaces and numbers all mixed up.

The function works well with overlaping characteres.

|         theString          | aString |
| -------------------------- | ------- |
| "661444444423666455678966" |  "55"   |
| "661444444423666455678966" |  "44"   |
| "6123666455678966"         |  "666"  |
| "66123666455678966"        |  "66"   |

Calling examples:
1. print("Number of occurrences: ", find_all("123666455556785555966", "5555"))
   
   output:
           Found in position:  7
           Found in position:  14
           Number of occurrences:  2
   
2. print("Number of occorrences: ", find_all("Allowed Hello Hollow", "ll "))

   output:
          Found in position:  1
          Found in position:  10
          Found in position:  16
          Number of occurrences:  3

3. print("Number of occorrences: ", find_all("Aaa bbbcd$#@@abWebbrbbbbrr 123", "bbb"))

   output:
         Found in position:  4
         Found in position:  21
         Number of occurrences:  2
         

def find_all(theString, aString):
    count = 0
    i = len(aString)
    x = 0

    while x < len(theString) - (i-1): 
        if theString[x:x+i] == aString:        
            print("Found in position: ", x)
            x=x+i
            count=count+1
        else:
            x=x+1
    return count

By default, Log4j logs to standard output and that means you should be able to see log messages on your Eclipse's console view. To log to a file you need to use a FileAppender explicitly by defining it in a log4j.properties file in your classpath.

Create the following log4j.properties file in your classpath. This allows you to log your message to both a file as well as your console.

log4j.rootLogger=debug, stdout, file

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

# Pattern to output the caller's file name and line number.
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n

log4j.appender.file=org.apache.log4j.FileAppender
log4j.appender.file.File=example.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%p %t %c - %m%n

Note: The above creates an example.log in your current working directory (i.e. Eclipse's project directory) so that the same log4j.properties could work with different projects without overwriting each other's logs.

If you are using Windows, you should set the same environment variables, but Windows style:

set http_proxy=<your_http_proxy:proxy_port>
set https_proxy=<your_https_proxy:proxy_port>

That will work for your current cmd.exe. If you want to do this more permanent, y suggest you to use environment variables on your system.

As @kojiro said, you don't want to "run" this file. Source it as he says. It should get "sourced" at startup. Sourcing just means running every line in the file, including the one you want to get run. If you want to make sure a folder is in a certain path environment variable (as it seems you want from one of your comments on another solution), execute

$ echo $PATH

At the command line. If you want to check that your ~/.bash_profile is being sourced, either at startup as it should be, or when you source it manually, enter the following line into your ~/.bash_profile file:

$ echo "Hello I'm running stuff in the ~/.bash_profile!"

Magically add Table View Header in swift

Recently I tried this.

I needed one and only one header in the whole UITableView.

Like I wanted a UIImageView on the top of the TableView. So I added a UIImageView on top of the UITableViewCell and automatically it was added as a tableViewHeader. Now I connect the ImageView to the ViewController and added the Image.

I was confused because I did something like this for the first time. So to clear my confusion open the xml format of the MainStoryBoard and found the Image View was added as a header.

It worked for me. Thanks xCode and swift.

I have solved this problem You just need to Create file in Android Folder

Go android folder

Create file local.properties

then just add this code in local.properties file:-

If you are using MacBook then sdk.dir=/Users/USERNAME/Library/android/sdk

if you are using Windows then sdk.dir=C:\Users\USERNAME\AppData\Local\Android\sdk

if you are using Linux then sdk.dir = /home/USERNAME/Android/sdk

if you want to know what is your system USERNAME then just use command for Mac whoami

and then just rerun command react-native run-android

Thanks :)

Do the following steps to resolve the problem

1. Ensure that the JDK is already installed.

2. If the installer is on a CD, Copy the EXE file for the Netbeans 6.5.1 installer onto your hard disk.

3. Note the location of the installer.

4. Open a Command Prompt running as administrator: Go to Start button > All Programs > Accessories Right click Command Prompt Select Run as administrator

5. In the Command Prompt use the cd command to change to the directory containing the installer.

6. Execute the following command to extract the contents of the installer: [Note: You might need to change the name of the installer to match the one you have.]

   netbeans-6.5.1-ml-java-windows.exe --extract

7. Execute the following command to manually execute the installer:

   java -jar bundle.jar

You will see rapid scrolling output in the Command Prompt window for a few moments, then the installer window will appear to begin the installation process.

I had this issue on Mac and it was related to the openssl package being an older version of what it was required by pycurl. pycurl can use other ssl libraries rather than openssl as per my understanding of it. Verify which ssl library you're using and update as it is very likely to fix the issue.

I fixed this by:

• running brew upgrade
• downloaded the latest pycurl-x.y.z.tar.gz from http://pycurl.io/
• extracted the package above and change directory into it
• ran python setup.py --with-openssl install as openssl is the library I have installed. If you're ssl library is either gnutls or nss then will have to use --with-gnutls or --with-nss accordingly. You'll be able to find more installation info in their github repository.

You could also put: (load_essentials.js:)

Content_x000D_
<footer id="myFooter"></footer>_x000D_
_x000D_
<script src="load_essentials.js"></script>

it is better that you use the following query to get all column names easily

Show columns from tablename

Public Function _
CreateTextArrayFromSourceTexts(ParamArray SourceTexts() As Variant) As String()

    ReDim TargetTextArray(0 To UBound(SourceTexts)) As String
    
    For SourceTextsCellNumber = 0 To UBound(SourceTexts)
        TargetTextArray(SourceTextsCellNumber) = SourceTexts(SourceTextsCellNumber)
    Next SourceTextsCellNumber

    CreateTextArrayFromSourceTexts = TargetTextArray
End Function

Example:

Dim TT() As String
TT = CreateTextArrayFromSourceTexts("hi", "bye", "hi", "bcd", "bYe")

Result:

TT(0)="hi"
TT(1)="bye"
TT(2)="hi"
TT(3)="bcd"
TT(4)="bYe"

Enjoy!

Edit: I removed the duplicatedtexts deleting feature and made the code smaller and easier to use.

Declaring variables inside or outside of a loop, It's the result of JVM specifications But in the name of best coding practice it is recommended to declare the variable in the smallest possible scope (in this example it is inside the loop, as this is the only place where the variable is used). Declaring objects in the smallest scope improve readability. The scope of local variables should always be the smallest possible. In your example I presume str is not used outside of the while loop, otherwise you would not be asking the question, because declaring it inside the while loop would not be an option, since it would not compile.

Does it make a difference if I declare variables inside or outside a , Does it make a difference if I declare variables inside or outside a loop in Java? Is this for(int i = 0; i < 1000; i++) { int At the level of the individual variable there is no significant difference in effeciency, but if you had a function with 1000 loops and 1000 variables (never mind the bad style implied) there could be systemic differences because all the lives of all the variables would be the same instead of overlapped.

Declaring Loop Control Variables Inside the for Loop, When you declare a variable inside a for loop, there is one important point to remember: the scope of that variable ends when the for statement does. (That is, the scope of the variable is limited to the for loop.) This Java Example shows how to declare multiple variables in Java For loop using declaration block.

For setting value in hidden field do in the following way:

@Html.HiddenFor(model => model.title, 
                new { id= "natureOfVisitField", Value = @Model.title})

It will work

Interfaces are abstract sets of defined available functionality.

Whether or not a method in that interface behaves as static or not is an implementation detail that should be hidden behind the interface. It would be wrong to define an interface method as static because you would be unnecessarily forcing the method to be implemented in a certain way.

If methods were defined as static, the class implementing the interface wouldn't be as encapsulated as it could be. Encapsulation is a good thing to strive for in object oriented design (I won't go into why, you can read that here: http://en.wikipedia.org/wiki/Object-oriented). For this reason, static methods aren't permitted in interfaces.

Lots of good answers here, just out of curiosity after looking into this today, is it not best to use setInterval rather than the setTimeout?

setInterval(function() {
location.reload();
}, 30000);

let me know you thoughts.

You can ssh directly from the Terminal on Mac, but you need to use a .PEM key rather than the putty .PPK key. You can use PuttyGen on Windows to convert from .PEM to .PPK, I'm not sure about the other way around though.

You can also convert the key using putty for Mac via port or brew:

sudo port install putty

or

brew install putty

This will also install puttygen. To get puttygen to output a .PEM file:

puttygen privatekey.ppk -O private-openssh -o privatekey.pem

Once you have the key, open a terminal window and:

ssh -i privatekey.pem [email protected]

The private key must have tight security settings otherwise SSH complains. Make sure only the user can read the key.

chmod go-rw privatekey.pem

If you don't want to deal with the pain of the conversion every time simply create an extension method.

public static class Extensions
{
    public static SolidColorBrush ToBrush(this string HexColorString)
    {
        return (SolidColorBrush)(new BrushConverter().ConvertFrom(HexColorString));
    }    
}

Then use like this: BackColor = "#FFADD8E6".ToBrush()

Alternately if you could provide a method to do the same thing.

public SolidColorBrush BrushFromHex(string hexColorString)
{
    return (SolidColorBrush)(new BrushConverter().ConvertFrom(hexColorString));
}

BackColor = BrushFromHex("#FFADD8E6");

Setup IIS on the network server and change the path to http://server/path/to/file.txt

try this=> numpy.array(yourvariable) followed by the command to compare, whatever you wish to.

If you put all your values in an array, at least you can use string.Join.

string[] myValues = new string[] { ... };
string csvString = string.Join(",", myValues);

You can also use the overload of string.Join that takes params string as the second parameter like this:

string csvString = string.Join(",", value1, value2, value3, ...);

You need to switch your values:

/* No greater than 900px, no less than 400px */
@media (max-width:900px) and (min-width:400px) {
    .foo {
        display:none;
    }
}?

        + identifier("Win32_DiskDrive", "Manufacturer")
        + identifier("Win32_DiskDrive", "Signature")
        + identifier("Win32_DiskDrive", "TotalHeads");
    }
    //Motherboard ID

In tensorflow you create graphs and pass values to that graph. Graph does all the hardwork and generate the output based on the configuration that you have made in the graph. Now When you pass values to the graph then first you need to create a tensorflow session.

tf.Session()

Once session is initialized then you are supposed to use that session because all the variables and settings are now part of the session. So, there are two ways to pass external values to the graph so that graph accepts them. One is to call the .run() while you are using the session being executed.

Other way which is basically a shortcut to this is to use .eval(). I said shortcut because the full form of .eval() is

tf.get_default_session().run(values)

You can check that yourself. At the place of values.eval() run tf.get_default_session().run(values). You must get the same behavior.

what eval is doing is using the default session and then executing run().

Add the class constraint as the first constraint to your generic type.

Difference between greedy method and dynamic programming are given below :

1. Greedy method never reconsiders its choices whereas Dynamic programming may consider the previous state.

2. Greedy algorithm is less efficient whereas Dynamic programming is more efficient.

3. Greedy algorithm have a local choice of the sub-problems whereas Dynamic programming would solve the all sub-problems and then select one that would lead to an optimal solution.

4. Greedy algorithm take decision in one time whereas Dynamic programming take decision at every stage.

1. create a new python file in the directory of the file.
2. type import (the name of the file without the extension)
3. run the file
4. open the directory, then find the pycache folder
5. inside should be your .pyc file

Zambri's answer found here is the best.

File.open("out.txt", '<OPTION>') {|f| f.write("write your stuff here") }

where your options for <OPTION> are:

r - Read only. The file must exist.

w - Create an empty file for writing.

a - Append to a file.The file is created if it does not exist.

r+ - Open a file for update both reading and writing. The file must exist.

w+ - Create an empty file for both reading and writing.

a+ - Open a file for reading and appending. The file is created if it does not exist.

In your case, w is preferable.

It's the default SSH port and SFTP is usually carried over an SSH tunnel.

In my opinion, uniqueidentifier / GUID is neither a varchar nor an nvarchar but a char(36). Therefore I use:

CAST(xyz AS char(36))

You could get the whole collection as an object, rather than array like this:

async getMarker() {
    const snapshot = await firebase.firestore().collection('events').get()
    const collection = {};
    snapshot.forEach(doc => {
        collection[doc.id] = doc.data();
    });
    return collection;
}

That would give you a better representation of what's in firestore. Nothing wrong with an array, just another option.

My initial post is incorrectly declared as "compile time". It's not, it's even impossible in current C++ standard. The constexpr does NOT means the function always do compile-time computation. Thanks Richard Hodges for correction.

window.location.hostname is a good start. But it includes sub-domains, which you probably want to remove. E.g. if the hostname is www.example.com, you probably want just the example.com bit.

There are, as ever, corner cases that make this fiddly, e.g. bbc.co.uk. The following regex works well for me:

let hostname = window.location.hostname;
// remove any subdomains, e.g. www.example.com -> example.com
let domain = hostname.match(/^(?:.*?\.)?(\w{3,}\.(?:\w{2,8}|\w{2,4}\.\w{2,4}))$/)[1];

If by chance your DbContext implementation is in a different project than your startup project and you run ef migrations, you'll see this error because the command will not be able to invoke the application's startup code leaving your database provider without a configuration. To fix it, you have to let ef migrations know where they're at.

dotnet ef migrations add MyMigration [-p <relative path to DbContext project>, -s <relative path to startup project>]

Both -s and -p are optionals that default to the current folder.

Although bash has a return statement, the only thing you can specify with it is the function's own exit status (a value between 0 and 255, 0 meaning "success"). So return is not what you want.

You might want to convert your return statement to an echo statement - that way your function output could be captured using $() braces, which seems to be exactly what you want.

Here is an example:

function fun1(){
  echo 34
}

function fun2(){
  local res=$(fun1)
  echo $res
}

Another way to get the return value (if you just want to return an integer 0-255) is $?.

function fun1(){
  return 34
}

function fun2(){
  fun1
  local res=$?
  echo $res
}

Also, note that you can use the return value to use boolean logic like fun1 || fun2 will only run fun2 if fun1 returns a non-0 value. The default return value is the exit value of the last statement executed within the function.

You have to dot source them:

. .\build_funtions.ps1
. .\build_builddefs.ps1

Edit: (after the code change)
There is no way for us to tell you whether you need or not to call your parent's __init__ (or any other function). Inheritance obviously would work without such call. It all depends on the logic of your code: for example, if all your __init__ is done in parent class, you can just skip child-class __init__ altogether.

consider the following example:

>>> class A:
    def __init__(self, val):
        self.a = val


>>> class B(A):
    pass

>>> class C(A):
    def __init__(self, val):
        A.__init__(self, val)
        self.a += val


>>> A(4).a
4
>>> B(5).a
5
>>> C(6).a
12

In my case div position was fixed , adding left position was not enough it started working only after adding display block

People answering about offline work is active is right. But it was located in different place in my case. To find it in the top bar menu select

1. View/Tool Windows/ Graddle
2. Toogle the offline button if active. It is a small rectangle with two centered slashes

In adittion you can clic the help menu in the top bar menu and write "gradle" and it suggest the locations.

Yes, you should use semicolons after every statement in JavaScript.

Your for loop doesn't need to just add one. You can loop by three.

for(int i = 0; i < theData.Length; i+=3)
{
  string value1 = theData[i];
  string value2 = theData[i+1];
  string value3 = theData[i+2];
}

Basically, you are just using indexes to grab the values in your array. One point to note here, I am not checking to see if you go past the end of your array. Make sure you are doing bounds checking!

At least in Node v8.9.1, you can just do

var json_data = require('/path/to/local/file.json');

and access all the elements of the JSON object.

For those not interested in USB debugging or using adb there is an easier solution. In Android 6 (Not sure about prior version) there is an option under developer tools: Take Bug Report

Clicking this option will prepare a bug report and prompt you to save it to drive or have it sent in email.

I found this to be the easiest way to get logs. I don't like to turn on USB debugging.

With Sharepoint Designer you can edit the CAML of your XSLT List View.

If you set the Scope attribute of the View element to Recursive or RecursiveAll, which returns all Files and Folders, you can filter the documents by FileDirRef:

<Where>
   <Contains>
      <FieldRef Name='FileDirRef' />
      <Value Type='Lookup'>MyFolder</Value>
   </Contains>
</Where>

This returns all documents which contain the string 'MyFolder' in their path.

I found infos about this on http://platinumdogs.wordpress.com/2009/07/21/querying-document-libraries-or-pulling-teeth-with-caml/ and useful information abouts fields at http://blog.thekid.me.uk/archive/2007/03/21/wss-field-display-amp-internal-names-for-lists-amp-document-libraries.aspx

$x is always a scalar. The hint is the sigil $: any variable (or dereferencing of some other type) starting with $ is a scalar. (See perldoc perldata for more about data types.)

A reference is just a particular type of scalar. The built-in function ref will tell you what kind of reference it is. On the other hand, if you have a blessed reference, ref will only tell you the package name the reference was blessed into, not the actual core type of the data (blessed references can be hashrefs, arrayrefs or other things). You can use Scalar::Util 's reftype will tell you what type of reference it is:

use Scalar::Util qw(reftype);

my $x = bless {}, 'My::Foo';
my $y = { };

print "type of x: " . ref($x) . "\n";
print "type of y: " . ref($y) . "\n";
print "base type of x: " . reftype($x) . "\n";
print "base type of y: " . reftype($y) . "\n";

...produces the output:

type of x: My::Foo
type of y: HASH
base type of x: HASH
base type of y: HASH

For more information about the other types of references (e.g. coderef, arrayref etc), see this question: How can I get Perl's ref() function to return REF, IO, and LVALUE? and perldoc perlref.

Note: You should not use ref to implement code branches with a blessed object (e.g. $ref($a) eq "My::Foo" ? say "is a Foo object" : say "foo not defined";) -- if you need to make any decisions based on the type of a variable, use isa (i.e if ($a->isa("My::Foo") { ... or if ($a->can("foo") { ...). Also see polymorphism.

I find object.constructor.toString() return [object objectClass] in IE ,rather than function objectClass () {} returned in chome. So,I think the code in http://blog.magnetiq.com/post/514962277/finding-out-class-names-of-javascript-objects may not work well in IE.And I fixed the code as follows:

code:

var getObjectClass = function (obj) {
        if (obj && obj.constructor && obj.constructor.toString()) {
            
                /*
                 *  for browsers which have name property in the constructor
                 *  of the object,such as chrome 
                 */
                if(obj.constructor.name) {
                    return obj.constructor.name;
                }
                var str = obj.constructor.toString();
                /*
                 * executed if the return of object.constructor.toString() is 
                 * "[object objectClass]"
                 */
                 
                if(str.charAt(0) == '[')
                {
                        var arr = str.match(/\[\w+\s*(\w+)\]/);
                } else {
                        /*
                         * executed if the return of object.constructor.toString() is 
                         * "function objectClass () {}"
                         * for IE Firefox
                         */
                        var arr = str.match(/function\s*(\w+)/);
                }
                if (arr && arr.length == 2) {
                            return arr[1];
                        }
          }
          return undefined; 
    };
    

You probably want to have a list of supported encodings. For each file, try each encoding in turn, maybe starting with UTF-8. Every time you catch the MalformedInputException, try the next encoding.

The next solution helped me. Add to build.gradle

 compileKotlin {
    kotlinOptions.jvmTarget = "1.8"
}

compileTestKotlin {
    kotlinOptions.jvmTarget = "1.8"
}

(Assuming C, C++, Java, JavaScript)

| and & are bitwise operators while || and && are logical operators. Usually you'd want to use || and && for if statements and loops and such (i.e. for your examples above). The bitwise operators are for setting and checking bits within bitmasks.

I believe there is a difference. Let's rename them so that we can talk about them more easily:

const     double PI1 = 3.141592653589793;
constexpr double PI2 = 3.141592653589793;

Both PI1 and PI2 are constant, meaning you can not modify them. However only PI2 is a compile-time constant. It shall be initialized at compile time. PI1 may be initialized at compile time or run time. Furthermore, only PI2 can be used in a context that requires a compile-time constant. For example:

constexpr double PI3 = PI1;  // error

but:

constexpr double PI3 = PI2;  // ok

and:

static_assert(PI1 == 3.141592653589793, "");  // error

but:

static_assert(PI2 == 3.141592653589793, "");  // ok

As to which you should use? Use whichever meets your needs. Do you want to ensure that you have a compile time constant that can be used in contexts where a compile-time constant is required? Do you want to be able to initialize it with a computation done at run time? Etc.

as Frank said Firebase stores sequence of values in the format of "key": "Value" which is a Map structure

to get List from this sequence you have to

1. initialize GenericTypeIndicator with HashMap of String and your Object.
2. get value of DataSnapShot as GenericTypeIndicator into Map.
3. initialize ArrayList with HashMap values.

GenericTypeIndicator<HashMap<String, Object>> objectsGTypeInd = new GenericTypeIndicator<HashMap<String, Object>>() {};
Map<String, Object> objectHashMap = dataSnapShot.getValue(objectsGTypeInd);
ArrayList<Object> objectArrayList = new ArrayList<Object>(objectHashMap.values());

Works fine for me, Hope it helps.

Have a look at the documentation. You made the following mistakes. Firstly, ps.executeQuery() doesn't have any parameters. Instead you passed the SQL query into it.

Secondly, regarding the prepared statement, you have to use the ? symbol if want to pass any parameters. And later bind it using

setXXX(index, value) 

Here xxx stands for the data type.

I dont think anyone has answered the question correctly.So, for anyone else who has the same question, this should help :

Step 1 Go to Build>Generate Signed APK>Next (module selected would be your module , most often called "app")

Step 2 Click on create new

Step 3 Basically, fill in the form with the required details. The confusing bit it is where it asks for a Key Store Path. Click on the icon on the right with the 3 dots ("..."), which will open up a navigator window asking you to navigate and select a .jks file.Navigate to a folder where you want your keystore file saved and then at the File Name box at the bottom of that window, simply enter a name of your liking and the OK button will be clickable now. What is happening is that the window isnt really asking you chose a .jks file but rather it wants you to give it the location and name that you want it to have.

Step 4 Click on Next and then select Release and Voila ! you are done.

Run 'npm install' it will install all necessary pkg .

Suggestion 1

When you add an object to $stateProvider.state that object is then passed with the state. So you can add additional properties which you can read later on when needed.

Example route configuration

$stateProvider
.state('public', {
    abstract: true,
    module: 'public'
})
.state('public.login', {
    url: '/login',
    module: 'public'
})
.state('tool', {
    abstract: true,
    module: 'private'
})
.state('tool.suggestions', {
    url: '/suggestions',
    module: 'private'
});

The $stateChangeStart event gives you acces to the toState and fromState objects. These state objects will contain the configuration properties.

Example check for the custom module property

$rootScope.$on('$stateChangeStart', function(e, toState, toParams, fromState, fromParams) {
    if (toState.module === 'private' && !$cookies.Session) {
        // If logged out and transitioning to a logged in page:
        e.preventDefault();
        $state.go('public.login');
    } else if (toState.module === 'public' && $cookies.Session) {
        // If logged in and transitioning to a logged out page:
        e.preventDefault();
        $state.go('tool.suggestions');
    };
});

I didn't change the logic of the cookies because I think that is out of scope for your question.

Suggestion 2

You can create a Helper to get you this to work more modular.

Value publicStates

myApp.value('publicStates', function(){
    return {
      module: 'public',
      routes: [{
        name: 'login', 
        config: { 
          url: '/login'
        }
      }]
    };
});

Value privateStates

myApp.value('privateStates', function(){
    return {
      module: 'private',
      routes: [{
        name: 'suggestions', 
        config: { 
          url: '/suggestions'
        }
      }]
    };
});

The Helper

myApp.provider('stateshelperConfig', function () {
  this.config = {
    // These are the properties we need to set
    // $stateProvider: undefined
    process: function (stateConfigs){
      var module = stateConfigs.module;
      $stateProvider = this.$stateProvider;
      $stateProvider.state(module, {
        abstract: true,
        module: module
      });
      angular.forEach(stateConfigs, function (route){
        route.config.module = module;
        $stateProvider.state(module + route.name, route.config);
      });
    }
  };

  this.$get = function () {
    return {
      config: this.config
    };
  };
});

Now you can use the helper to add the state configuration to your state configuration.

myApp.config(['$stateProvider', '$urlRouterProvider', 
    'stateshelperConfigProvider', 'publicStates', 'privateStates',
  function ($stateProvider, $urlRouterProvider, helper, publicStates, privateStates) {
    helper.config.$stateProvider = $stateProvider;
    helper.process(publicStates);
    helper.process(privateStates);
}]);

This way you can abstract the repeated code, and come up with a more modular solution.

Note: the code above isn't tested

If you make

overflow: hidden in the outer div and overflow-y: scroll in the inner div it will work.

There's a solution for multi-line text with pure css. It's called line-clamp, but it only works in webkit browsers. There is however a way to mimic this in all modern browsers (everything more recent than IE8.) Also, it will only work on solid backgrounds because you need a background-image to hide the last words of the last line. Here's how it goes:

Given this html:

<p class="example" id="example-1">
    Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.
</p>

Here's the CSS:

p {
    position:relative;
    line-height:1.4em;
    height:4.2em;      /* 3 times the line-height to show 3 lines */
}
p::after {
    content:"...";
    font-weight:bold;
    position:absolute;
    bottom:0;
    right:0;
    padding:0 20px 1px 45px;
    background:url(ellipsis_bg.png) repeat-y;
}

ellipsis_bg.png being an image of the same color of your background, that would be about 100px wide and have the same height as your line-height.

It's not very pretty, as your text may be cut of in the middle of a letter, but it may be useful in some cases.

Reference: http://www.css-101.org/articles/line-clamp/line-clamp_for_non_webkit-based_browsers.php

But this is obviously performing a 'string' comparison

No. The string will be automatically cast into a DATETIME value.

See 11.2. Type Conversion in Expression Evaluation.

When an operator is used with operands of different types, type conversion occurs to make the operands compatible. Some conversions occur implicitly. For example, MySQL automatically converts numbers to strings as necessary, and vice versa.

Decimal is a value type, so if you wish to check whether it has a value other than the value it was initialised with (zero) you can use the condition myDecimal != default(decimal).

Otherwise you should possibly consider the use of a nullable (decimal?) type and the use a condition such as myNullableDecimal.HasValue

In recent versions of jQuery, setting "dataType" to an appropriate value also sets the accepts header. For instance, dataType: "json" sets the accept header to Accept: application/json, text/javascript, */*; q=0.01.

The u means the strings are unicode. Translate all the strings to ascii to get rid of it:

a.encode('ascii', 'ignore')

When having to fetch multiple collections, you need to:

1. JOIN FETCH one collection
2. Use the Hibernate.initialize for the remaining collections.

So, in your case, you need a first JPQL query like this one:

MyEntity entity = session.createQuery("select e from MyEntity e join fetch e.addreses where e.id 
= :id", MyEntity.class)
.setParameter("id", entityId)
.getSingleResult();

Hibernate.initialize(entity.persons);

This way, you can achieve your goal with 2 SQL queries and avoid a Cartesian Product.

Quick one in TSQL

SELECT a.*
FROM emails a
INNER JOIN 
  (SELECT email,
    MIN(id) as id
  FROM emails 
  GROUP BY email 
) AS b
  ON a.email = b.email 
  AND a.id = b.id;

One solution is to implement an OnScrollListener and make changes (like adding items, etc.) to the ListAdapter at a convenient state in its onScroll method.

The following ListActivity shows a list of integers, starting with 40, adding items when the user scrolls to the end of the list.

public class Test extends ListActivity implements OnScrollListener {

    Aleph0 adapter = new Aleph0();

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setListAdapter(adapter); 
        getListView().setOnScrollListener(this);
    }

    public void onScroll(AbsListView view,
        int firstVisible, int visibleCount, int totalCount) {

        boolean loadMore = /* maybe add a padding */
            firstVisible + visibleCount >= totalCount;

        if(loadMore) {
            adapter.count += visibleCount; // or any other amount
            adapter.notifyDataSetChanged();
        }
    }

    public void onScrollStateChanged(AbsListView v, int s) { }    

    class Aleph0 extends BaseAdapter {
        int count = 40; /* starting amount */

        public int getCount() { return count; }
        public Object getItem(int pos) { return pos; }
        public long getItemId(int pos) { return pos; }

        public View getView(int pos, View v, ViewGroup p) {
                TextView view = new TextView(Test.this);
                view.setText("entry " + pos);
                return view;
        }
    }
}

You should obviously use separate threads for long running actions (like loading web-data) and might want to indicate progress in the last list item (like the market or gmail apps do).

Bitcode (iOS, watchOS)

Bitcode is an intermediate representation of a compiled program. Apps you upload to iTunes Connect that contain bitcode will be compiled and linked on the App Store. Including bitcode will allow Apple to re-optimize your app binary in the future without the need to submit a new version of your app to the store.

Basically this concept is somewhat similar to java where byte code is run on different JVM's and in this case the bitcode is placed on iTune store and instead of giving the intermediate code to different platforms(devices) it provides the compiled code which don't need any virtual machine to run.

Thus we need to create the bitcode once and it will be available for existing or coming devices. It's the Apple's headache to compile an make it compatible with each platform they have.

Devs don't have to make changes and submit the app again to support new platforms.

Let's take the example of iPhone 5s when apple introduced x64 chip in it. Although x86 apps were totally compatible with x64 architecture but to fully utilise the x64 platform the developer has to change the architecture or some code. Once s/he's done the app is submitted to the app store for the review.

If this bitcode concept was launched earlier then we the developers doesn't have to make any changes to support the x64 bit architecture.

Following on @Arne Mertz's answer, as of C++11 std::ios_base::failure inherits from system_error (see http://www.cplusplus.com/reference/ios/ios_base/failure/), which contains both the error code and message that strerror(errno) would return.

std::ifstream f;

// Set exceptions to be thrown on failure
f.exceptions(std::ifstream::failbit | std::ifstream::badbit);

try {
    f.open(fileName);
} catch (std::system_error& e) {
    std::cerr << e.code().message() << std::endl;
}

This prints No such file or directory. if fileName doesn't exist.

This error can occur on anything that requires elevated privileges in Windows.

It happens when the "Application Information" service is disabled in Windows services. There are a few viruses that use this as an attack vector to prevent people from removing the virus. It also prevents people from installing software to remove viruses.

The normal way to fix this would be to run services.msc, or to go into Administrative Tools and run "Services". However, you will not be able to do that if the "Application Information" service is disabled.

Instead, reboot your computer into Safe Mode (reboot and press F8 until the Windows boot menu appears, select Safe Mode with Networking). Then run services.msc and look for services that are designated as "Disabled" in the Startup Type column. Change these "Disabled" services to "Automatic".

Make sure the "Application Information" service is set to a Startup Type of "Automatic".

When you are done enabling your services, click Ok at the bottom of the tool and reboot your computer back into normal mode. The problem should be resolved when Windows reboots.

delegates are the best option for sending data from one form to another.

public partial class frmImportContact : Form
{
     public delegate void callback_data(string someData);
    public event callback_data getData_CallBack;

    private void button_Click(object sender, EventArgs e)
    {
      string myData = "Top Secret Data To Share";
      getData_CallBack(myData);
    }

}

public partial class frmHireQuote : Form
{
     private void Button_Click(object sender, EventArgs e)
    {

      frmImportContact obj = new frmImportContact();
      obj.getData_CallBack += getData;
    }

    private void getData(string someData)
    {
         MessageBox.Show("someData");
    }
}

DateTime.Today.ToString("MM/dd/yy")

Look at the docs for custom date and time format strings for more info.

(Oh, and I hope this app isn't destined for other cultures. That format could really confuse a lot of people... I've never understood the whole month/day/year thing, to be honest. It just seems weird to go "middle/low/high" in terms of scale like that.)

Others cultures really are a problem. For example, that code in portugues returns someting like 01-01-01 instead of 01/01/01. I also don't undestand why...

To resolve that problem i do someting like this:

        IFormatProvider yyyymmddFormat = new System.Globalization.CultureInfo(String.Empty, false);
        return date.ToString("MM/dd/yy", yyyymmddFormat);

To do this you want to loop through each row of your query results and use this info for each of your drop down's options. You should be able to adjust the code below fairly easily to meet your needs.

// Assume $db is a PDO object
$query = $db->query("YOUR QUERY HERE"); // Run your query

echo '<select name="DROP DOWN NAME">'; // Open your drop down box

// Loop through the query results, outputing the options one by one
while ($row = $query->fetch(PDO::FETCH_ASSOC)) {
   echo '<option value="'.$row['something'].'">'.$row['something'].'</option>';
}

echo '</select>';// Close your drop down box

SOLUTION:

Run the emulator from the command line:

sdk/tools> ./emulator-x86 -avd <DeviceName> -partition-size 1024 -gpu on

Then I launched the app from the command line as well (using built-in Cordova/PhoneGap tools):

myapp/cordova> ./run

BACKGROUND

I believe this is some sort of hardware compatibility issue. I came across this problem when following the PhoneGap 2.4.0 Getting Started Instructions. I followed their advice to install the Intel Hardware Accelerated Execution Manager, and I think this is the source of my trouble. Eclipse uses the emulator64-x86 program (in the sdk/tools folder) to launch the emulator. I could not find any way inside of Eclipse to change this but I found by following the "Tips & Tricks" section of the Intel HAXM web page that I could get the emulator to run successfully from the command line by using the emulator-x86 program instead. I'm not sure why the emulator64-x86 program doesn't work on my system. I confirmed at the Apple website that I do have a 64-bit processor.

My system:

• OSX 10.6.8
• 2x2.26 GHx Quad-core Intel Xeon
• 6 GB RAM
• ADT v21.1.0-569685
• Eclipse 3.8.0

My AVD:

• Device: Nexus One
• Target: Android 4.2.2 - API Level 17
• CPU: Intel Atom (x86)
• RAM: 512
• Internal Storage: 256
• SD Card: 128

I tried to install AWS via pip in El Capitan but this error appear

OSError: [Errno 1] Operation not permitted: '/var/folders/wm/jhnj0g_s16gb36y8kwvrgm7h0000gp/T/pip-wTnb_D-uninstall/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/six-1.4.1-py2.7.egg-info'

I found the answer here

sudo -H pip install awscli --upgrade --ignore-installed six

It works for me :)

Consider the case in which a service worker acts as an agnostic cache. Your only goal is serve the same resources that you would get from the network, but faster. Of course you can't ensure all the resources will be part of your origin (consider libraries served from CDNs, for instance). As the service worker has the potential of altering network responses, you need to guarantee you are not interested in the contents of the response, nor on its headers, nor even on the result. You're only interested on the response as a black box to possibly cache it and serve it faster.

This is what { mode: 'no-cors' } was made for.

For anyone else that comes across this post and might find it useful... There is actually nothing wrong with my code. I made the mistake of requesting client_credentials type access code instead of password access code (#facepalms). FYI I am using urlencoded post hence the use of querystring.. So for those that may be looking for some example code.. here is my full request

Big thanks to @swapnil for trying to help me debug this.

   const data = {
      grant_type: USER_GRANT_TYPE,
      client_id: CLIENT_ID,
      client_secret: CLIENT_SECRET,
      scope: SCOPE_INT,
      username: DEMO_EMAIL,
      password: DEMO_PASSWORD
    };



  axios.post(TOKEN_URL, Querystring.stringify(data))   
   .then(response => {
      console.log(response.data);
      USER_TOKEN = response.data.access_token;
      console.log('userresponse ' + response.data.access_token); 
    })   
   .catch((error) => {
      console.log('error ' + error);   
   });



const AuthStr = 'Bearer '.concat(USER_TOKEN); 
axios.get(URL, { headers: { Authorization: AuthStr } })
 .then(response => {
     // If request is good...
     console.log(response.data);
  })
 .catch((error) => {
     console.log('error ' + error);
  });

I wrote some test code to check JQueryUI drag/drop. The example shows how to drag an element from a container and drop it to another container.

If you manually call video.play() it should work:

<!DOCTYPE html>
<html>
<head>
  <script>
    function init() {
      enableVideoClicks();
    }

    function enableVideoClicks() {
      var videos = document.getElementsByTagName('video') || [];
      for (var i = 0; i < videos.length; i++) {
        // TODO: use attachEvent in IE
        videos[i].addEventListener('click', function(videoNode) {
          return function() {
            videoNode.play();
          };
        }(videos[i]));
      }
    }

Yes, this is possible. According to the SQLite FAQ:

A column declared INTEGER PRIMARY KEY will autoincrement.

select a.orgName,b.duplicate, a.id
from organizations a
inner join (
    SELECT orgName, COUNT(*) AS duplicate
    FROM organizations
    GROUP BY orgName
    HAVING COUNT(*) > 1
) b on o.orgName = oc.orgName
group by a.orgName,a.id

You should use gnuplot and be sure to issue the command "set term dumb" after starting up. You can also give a row and column count. Here is the output from gnuplot if you issue "set term dumb 64 10" and then "plot sin(x)":

 

    1 ++-----------****-----------+--***-------+------****--++
  0.6 *+          **+  *          +**   *      sin(x)*******++
  0.2 +*         *      *         **     **         *     **++
    0 ++*       **       *       **       *       **       *++
 -0.4 ++**     *         **     **         *      *         *+
 -0.8 ++ **   *     +      *   ** +         *  +**          +*
   -1 ++--****------+-------***---+----------****-----------++
     -10           -5             0            5             10

It looks better at 79x24 (don't use the 80th column on an 80x24 display: some curses implementations don't always behave well around the last column).

I'm using gnuplot v4, but this should work on slightly older or newer versions.

Alternative syntax using the -Not operator and depending on your preference for readability:

if( -Not (Test-Path -Path $TARGETDIR ) )
{
    New-Item -ItemType directory -Path $TARGETDIR
}

After a bit of struggle, I found a better solution.

1. create a directory with name: swagger

   mkdir C:\swagger
   

If you are in Linux, try:

    mkdir /opt/swagger

2. get swagger-editor with below command:

   git clone https://github.com/swagger-api/swagger-editor.git
   

3. go into swagger-editor directory that is created now

   cd swagger-editor
   

4. now get swagger-ui with below command:

   git clone https://github.com/swagger-api/swagger-ui.git
   

5. now, copy your swagger file, I copied to below path:

   ./swagger-editor/api/swagger/swagger.json
   

6. all setup is done, run the swagger-edit with below commands

   npm install
   npm run build
   npm start
   

7. You will be prompted 2 URLs, one of them might look like:

   http://127.0.0.1:3001/
   

   Above is swagger-editor URL

8. Now browse to:

   http://127.0.0.1:3001/swagger-ui/dist/
   

   Above is swagger-ui URL

Thats all.

You can now browse files from either of swagger-ui or swagger-editor

It will take time to install/build, but once done, you will see great results.

It took roughly 2 days of struggle for me, one-time installation took only about 5 minutes.

Now, on top-right, you can browse to your local file.

best of luck.

As lots of others have said, you will need to use multiple ALTER COLUMN statements, one for each column you want to modify.

If you want to modify all or several of the columns in your table to the same datatype (such as expanding a VARCHAR field from 50 to 100 chars), you can generate all the statements automatically using the query below. This technique is also useful if you want to replace the same character in multiple fields (such as removing \t from all columns).

SELECT
     TABLE_CATALOG
    ,TABLE_SCHEMA
    ,TABLE_NAME
    ,COLUMN_NAME
    ,'ALTER TABLE ['+TABLE_SCHEMA+'].['+TABLE_NAME+'] ALTER COLUMN ['+COLUMN_NAME+'] VARCHAR(300)' as 'code'
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'your_table' AND TABLE_SCHEMA = 'your_schema'

This generates an ALTER TABLE statement for each column for you.

This should work in modern browsers:

input[value]:not([value=""])

It selects all inputs with value attribute and then select inputs with non empty value among them.

Dart lang:

import 'dart:math' show cos, sqrt, asin;

double calculateDistance(LatLng l1, LatLng l2) {
  const p = 0.017453292519943295;
  final a = 0.5 -
      cos((l2.latitude - l1.latitude) * p) / 2 +
      cos(l1.latitude * p) *
          cos(l2.latitude * p) *
          (1 - cos((l2.longitude - l1.longitude) * p)) /
          2;
  return 12742 * asin(sqrt(a));
}

This is the code to create dropdown in Angular 7, 8, 9

.html file code

<div>
<label>Summary: </label>
<select (change)="SelectItem($event.target.value)" class="select">
  <option value="0">--All--</option>
  <option *ngFor="let item of items" value="{{item.Id.Value}}">
    {{item.Name}}
  </option>
</select>
</div>

.ts file code

SelectItem(filterVal: any)
{
    var id=filterVal;
    //code
}

items is an array which should be initialized in .ts file.

Update April 2016 - for VS2013+

Microsoft started to address the issue in late 2015 by releasing VisualStudioUninstaller.

They abandoned the solution for a while; however work has begun again again as of April 2016.

There has finally been an official release for this uninstaller in April 2016 which is described as being "designed to cleanup/scorch all Preview/RC/RTM releases of Visual Studio 2013, Visual Studio 2015 and Visual Studio vNext".

Original Answer - for VS2010, VS2012

Note that the following two solutions still leave traces (such as registry files) and can't really be considered a 'clean' uninstall (see the final section of the answer for a completely clean solution).

Solution 1 - for: VS 2010

There's an uninstaller provided by Microsoft called the Visual Studio 2010 Uninstall Utility. It comes with three options:

1. Default (VS2010_Uninstall-RTM.ENU.exe)
2. Full (VS2010_Uninstall-RTM.ENU.exe /full)
3. Complete (VS2010_Uninstall-RTM.ENU.exe /full /netfx)

The above link explains the uninstaller in greater detail - I recommend reading the comments on the article before using it as some have noted problems (and workarounds) when service packs are installed. Afterwards, use something like CCleaner to remove the leftover registry files.

Here is the link to the download page of the VS2010 UU.

Solution 2 - for: VS 2010, VS 2012

Microsoft provide an uninstall /force feature that removes most remnants of either VS2010 or VS2012 from your computer.

MSDN: How to uninstall Visual Studio 2010/2012. From the link:

Warning: Running this command may remove some packages even if they are still in use like those listed in Optional shared packages.

1. Download the setup application you used to originally install Visual Studio 2012. If you installed from media, please insert that media.
2. Open a command prompt. Click Run on the Start menu (Start + R). Type cmd and press OK (Enter).
3. Type in the full path to the setup application and pass the following command line switches: /uninstall /force Example: D:\vs_ultimate.exe /uninstall /force
4. Click the Uninstall button and follow the prompts.

Afterwards, use something like CCleaner to remove the leftover registry files.

A completely clean uninstall?

Sadly, the only (current) way to achieve this is to follow dnLL's advice in their answer and perform a complete operating system reinstall. Then, in future, you could use Visual Studio inside a Virtual Machine instead and not have to worry about these issues again.

You might want to chose based on what is widely available. I had the same question and here are the results of my limited research.

Training set: A set of examples used for learning, that is to fit the parameters [i.e., weights] of the classifier.

Validation set: A set of examples used to tune the parameters [i.e., architecture, not weights] of a classifier, for example to choose the number of hidden units in a neural network.

Test set: A set of examples used only to assess the performance [generalization] of a fully specified classifier.

From ftp://ftp.sas.com/pub/neural/FAQ1.txt section "What are the population, sample, training set, design set, validation"

The error surface will be different for different sets of data from your data set (batch learning). Therefore if you find a very good local minima for your test set data, that may not be a very good point, and may be a very bad point in the surface generated by some other set of data for the same problem. Therefore you need to compute such a model which not only finds a good weight configuration for the training set but also should be able to predict new data (which is not in the training set) with good error. In other words the network should be able to generalize the examples so that it learns the data and does not simply remembers or loads the training set by overfitting the training data.

The validation data set is a set of data for the function you want to learn, which you are not directly using to train the network. You are training the network with a set of data which you call the training data set. If you are using gradient based algorithm to train the network then the error surface and the gradient at some point will completely depend on the training data set thus the training data set is being directly used to adjust the weights. To make sure you don't overfit the network you need to input the validation dataset to the network and check if the error is within some range. Because the validation set is not being using directly to adjust the weights of the netowork, therefore a good error for the validation and also the test set indicates that the network predicts well for the train set examples, also it is expected to perform well when new example are presented to the network which was not used in the training process.

Early stopping is a way to stop training. There are different variations available, the main outline is, both the train and the validation set errors are monitored, the train error decreases at each iteration (backprop and brothers) and at first the validation error decreases. The training is stopped at the moment the validation error starts to rise. The weight configuration at this point indicates a model, which predicts the training data well, as well as the data which is not seen by the network . But because the validation data actually affects the weight configuration indirectly to select the weight configuration. This is where the Test set comes in. This set of data is never used in the training process. Once a model is selected based on the validation set, the test set data is applied on the network model and the error for this set is found. This error is a representative of the error which we can expect from absolutely new data for the same problem.

EDIT:

Also, in the case you do not have enough data for a validation set, you can use crossvalidation to tune the parameters as well as estimate the test error.

There is no way to "discard" the time component.

DateTime.Today is the same as:

DateTime d = DateTime.Now.Date;

If you only want to display only the date portion, simply do that - use ToString with the format string you need.

For example, using the standard format string "D" (long date format specifier):

d.ToString("D");

I got the same error when I just copied the complete line but when I rewrite the code again i.e. instead of copy-paste, writing it completely then the error was no longer present.

Conclusion: There might be some unacceptable words to the language got copied giving rise to this error.

when you use the svn:// URI it uses port 3690 and probably won't use http proxy

Let's say you are writing a test case for a negative flow where the code being tested should raise an exception.

try{
   bizMethod(badData);
   fail(); // FAIL when no exception is thrown
} catch (BizException e) {
   assert(e.errorCode == THE_ERROR_CODE_U_R_LOOKING_FOR)
}

Maybe it is really late answer but if you want to navigate another page with param you can,

[routerLink]="['/user', user.id, 'details']"

also you shouldn't forget about routing config like ,

 [path: 'user/:id/details', component:userComponent, pathMatch: 'full']

Answer Background and Explanation

To understand this question, you must first understand what SHA256 is. SHA256 is a Cryptographic Hash Function. A Cryptographic Hash Function is a one-way function, whose output is cryptographically secure. This means it is easy to compute a hash (equivalent to encrypting data), but hard to get the original input using the hash (equivalent to decrypting the data). Since using a Cryptographic hash function means decrypting is computationally infeasible, so therefore you cannot perform decryption with SHA256.

What you want to use is a two-way function, but more specifically, a Block Cipher. A function that allows for both encryption and decryption of data. The functions mcrypt_encrypt and mcrypt_decrypt by default use the Blowfish algorithm. PHP's use of mcrypt can be found in this manual. A list of cipher definitions to select the cipher mcrypt uses also exists. A wiki on Blowfish can be found at Wikipedia. A block cipher encrypts the input in blocks of known size and position with a known key, so that the data can later be decrypted using the key. This is what SHA256 cannot provide you.

Code

$key = 'ThisIsTheCipherKey';

$ciphertext = mcrypt_encrypt(MCRYPT_BLOWFISH, $key, 'This is plaintext.', MCRYPT_MODE_CFB);

$plaintext = mcrypt_decrypt(MCRYPT_BLOWFISH, $key, $encrypted, MCRYPT_MODE_CFB);

Based on Ankur's answer but for us Swift users:

let urls = NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)
println("Possible sqlite file: \(urls)")

Put it inside ViewDidLoad and it will print out immediately upon execution of the app.

  window.location.href.slice(window.location.href.indexOf('?') + 1);

*nix: you can intercept SIGSEGV (usualy this signal is raised before crashing) and keep the info into a file. (besides the core file which you can use to debug using gdb for example).

win: Check this from msdn.

You can also look at the google's chrome code to see how it handles crashes. It has a nice exception handling mechanism.

<div class="row">
  <div class="col-4 alert alert-primary">
     1
  </div>
  <div class="col-8">
    <div class="row">
      <div class="col-6 alert alert-primary">
        2
      </div>
      <div class="col-6 alert alert-primary">
        3
      </div>
      <div class="col-6 alert alert-primary">
        4
      </div>
      <div class="col-6 alert alert-primary">
        5
      </div>
    </div>
  </div>
</div>
<div class="row">
  <div class="col-4 alert alert-primary">
    6
  </div>
  <div class="col-4 alert alert-primary">
    7
  </div>
  <div class="col-4 alert alert-primary">
    8
  </div>
</div>

If you want to do it in CSS:

#ID { cursor: none !important; }

You can also use CURRENT_TIMESTAMP for this.

According to BOL CURRENT_TIMESTAMP is the ANSI SQL euivalent to GETDATE()

DECLARE @LastChangeDate AS DATE;
SET @LastChangeDate = CURRENT_TIMESTAMP;

GRANTs on different objects are separate. GRANTing on a database doesn't GRANT rights to the schema within. Similiarly, GRANTing on a schema doesn't grant rights on the tables within.

If you have rights to SELECT from a table, but not the right to see it in the schema that contains it then you can't access the table.

The rights tests are done in order:

Do you have `USAGE` on the schema? 
    No:  Reject access. 
    Yes: Do you also have the appropriate rights on the table? 
        No:  Reject access. 
        Yes: Check column privileges.

Your confusion may arise from the fact that the public schema has a default GRANT of all rights to the role public, which every user/group is a member of. So everyone already has usage on that schema.

The phrase:

(assuming that the objects' own privilege requirements are also met)

Is saying that you must have USAGE on a schema to use objects within it, but having USAGE on a schema is not by itself sufficient to use the objects within the schema, you must also have rights on the objects themselves.

It's like a directory tree. If you create a directory somedir with file somefile within it then set it so that only your own user can access the directory or the file (mode rwx------ on the dir, mode rw------- on the file) then nobody else can list the directory to see that the file exists.

If you were to grant world-read rights on the file (mode rw-r--r--) but not change the directory permissions it'd make no difference. Nobody could see the file in order to read it, because they don't have the rights to list the directory.

If you instead set rwx-r-xr-x on the directory, setting it so people can list and traverse the directory but not changing the file permissions, people could list the file but could not read it because they'd have no access to the file.

You need to set both permissions for people to actually be able to view the file.

Same thing in Pg. You need both schema USAGE rights and object rights to perform an action on an object, like SELECT from a table.

(The analogy falls down a bit in that PostgreSQL doesn't have row-level security yet, so the user can still "see" that the table exists in the schema by SELECTing from pg_class directly. They can't interact with it in any way, though, so it's just the "list" part that isn't quite the same.)

A hash is an fixed sized integer that identifies a particular value. Each value needs to have its own hash, so for the same value you will get the same hash even if it's not the same object.

>>> hash("Look at me!")
4343814758193556824
>>> f = "Look at me!"
>>> hash(f)
4343814758193556824

Hash values need to be created in such a way that the resulting values are evenly distributed to reduce the number of hash collisions you get. Hash collisions are when two different values have the same hash. Therefore, relatively small changes often result in very different hashes.

>>> hash("Look at me!!")
6941904779894686356

These numbers are very useful, as they enable quick look-up of values in a large collection of values. Two examples of their use are Python's set and dict. In a list, if you want to check if a value is in the list, with if x in values:, Python needs to go through the whole list and compare x with each value in the list values. This can take a long time for a long list. In a set, Python keeps track of each hash, and when you type if x in values:, Python will get the hash-value for x, look that up in an internal structure and then only compare x with the values that have the same hash as x.

The same methodology is used for dictionary lookup. This makes lookup in set and dict very fast, while lookup in list is slow. It also means you can have non-hashable objects in a list, but not in a set or as keys in a dict. The typical example of non-hashable objects is any object that is mutable, meaning that you can change its value. If you have a mutable object it should not be hashable, as its hash then will change over its life-time, which would cause a lot of confusion, as an object could end up under the wrong hash value in a dictionary.

Note that the hash of a value only needs to be the same for one run of Python. In Python 3.3 they will in fact change for every new run of Python:

$ /opt/python33/bin/python3
Python 3.3.2 (default, Jun 17 2013, 17:49:21) 
[GCC 4.6.3] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> hash("foo")
1849024199686380661
>>> 
$ /opt/python33/bin/python3
Python 3.3.2 (default, Jun 17 2013, 17:49:21) 
[GCC 4.6.3] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> hash("foo")
-7416743951976404299

This is to make is harder to guess what hash value a certain string will have, which is an important security feature for web applications etc.

Hash values should therefore not be stored permanently. If you need to use hash values in a permanent way you can take a look at the more "serious" types of hashes, cryptographic hash functions, that can be used for making verifiable checksums of files etc.

It can be done, but you need to change the phpMyAdmin configuration, read this post: http://www.danielmois.com/article/Manage_remote_databases_from_localhost_with_phpMyAdmin

If for any reason the link dies, you can use the following steps:

• Find phpMyAdmin's configuration file, called config.inc.php
• Find the $cfg['Servers'][$i]['host'] variable, and set it to the IP or hostname of your remote server
• Find the $cfg['Servers'][$i]['port'] variable, and set it to the remote mysql port. Usually this is 3306
• Find the $cfg['Servers'][$i]['user'] and $cfg['Servers'][$i]['password'] variables and set these to your username and password for the remote server

Without proper server configuration, the connection may be slower than a local connection for example, it's would probably be slightly faster to use IP addresses instead of host names to avoid the server having to look up the IP address from the hostname.

In addition, remember that your remote database's username and password is stored in plain text when you connect like this, so you should take steps to ensure that no one can access this config file. Alternatively, you can leave the username and password variables empty to be prompted to enter them each time you log in, which is a lot more secure.

Depends what you want to do.

If what you want is to retrieve the bytes that are remaining (between position and limit), then what you have will work. You could also just do:

ByteBuffer bb =..

byte[] b = new byte[bb.remaining()];
bb.get(b);

which is equivalent as per the ByteBuffer javadocs.

This is more or less a summary of three answers (by Sara Inés Calderón, klaxon and Gothburz), but as they all added something important, I consider it worth joining the solutions and adding some more explanation.

Considering your example, you can do calculations in your template using:

{{ 100 * (count/total) }}

However, this may result in a whole lot of decimal places, so using filters is a good way to go:

{{ 100 * (count/total) | number }}

By default, the number filter will leave up to three fractional digits, this is where the fractionSize argument comes in quite handy ({{ 100 * (count/total) | number:fractionSize }}), which in your case would be:

{{ 100 * (count/total) | number:0 }}

This will also round the result already:

angular.module('numberFilterExample', [])_x000D_
  .controller('ExampleController', ['$scope',_x000D_
    function($scope) {_x000D_
      $scope.val = 1234.56789;_x000D_
    }_x000D_
  ]);

  <body ng-app="numberFilterExample">_x000D_
    <table ng-controller="ExampleController">_x000D_
      <tr>_x000D_
        <td>No formatting:</td>_x000D_
        <td>_x000D_
          <span>{{ val }}</span>_x000D_
        </td>_x000D_
      </tr>_x000D_
      <tr>_x000D_
        <td>3 Decimal places:</td>_x000D_
        <td>_x000D_
          <span>{{ val | number }}</span> (default)_x000D_
        </td>_x000D_
      </tr>_x000D_
      <tr>_x000D_
        <td>2 Decimal places:</td>_x000D_
        <td><span>{{ val | number:2 }}</span></td>_x000D_
      </tr>_x000D_
      <tr>_x000D_
        <td>No fractions: </td>_x000D_
        <td><span>{{ val | number:0 }}</span> (rounded)</td>_x000D_
      </tr>_x000D_
    </table>_x000D_
  </body>_x000D_
</html>

Last thing to mention, if you rely on an external data source, it probably is good practise to provide a proper fallback value (otherwise you may see NaN or nothing on your site):

{{ (100 * (count/total) | number:0) || 0 }}

Sidenote: Depending on your specifications, you may even be able to be more precise with your fallbacks/define fallbacks on lower levels already (e.g. {{(100 * (count || 10)/ (total || 100) | number:2)}}). Though, this may not not always make sense..

Per the Javadoc:

Returns the value of a request parameter as a String, or null if the parameter does not exist.

Do note that it is possible to submit an empty parameter - such that the parameter exists, but has no value. For example, I could include &log=&somethingElse into the URL to enable logging, without needing to specify &log=true. In this case, the value will be an empty String ("").

I had a bit of trouble getting this to work as well. Using brouxhaha's answer got me 90% of the way to what I was looking for. But the padding adjust wouldn't allow me to put the text anywhere I wanted. Using top and left seemed to work better for my purposes.

    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;

    left: 20%;
}

... right now it happens only to the website I'm testing. I can't post it here because it's confidential.

Then I guess it is one of the sites which is incompatible with TLS1.2. The openssl as used in 12.04 does not use TLS1.2 on the client side while with 14.04 it uses TLS1.2 which might explain the difference. To work around try to explicitly use --secure-protocol=TLSv1. If this does not help check if you can access the site with openssl s_client -connect ... (probably not) and with openssl s_client -tls1 -no_tls1_1, -no_tls1_2 ....

Please note that it might be other causes, but this one is the most probable and without getting access to the site everything is just speculation anyway.

The assumed problem in detail: Usually clients use the most compatible handshake to access a server. This is the SSLv23 handshake which is compatible to older SSL versions but announces the best TLS version the client supports, so that the server can pick the best version. In this case wget would announce TLS1.2. But there are some broken servers which never assumed that one day there would be something like TLS1.2 and which refuse the handshake if the client announces support for this hot new version (from 2008!) instead of just responding with the best version the server supports. To access these broken servers the client has to lie and claim that it only supports TLS1.0 as the best version.

Is Ubuntu 14.04 or wget 1.15 not compatible with TLS 1.0 websites? Do I need to install/download any library/software to enable this connection?

The problem is the server, not the client. Most browsers work around these broken servers by retrying with a lower version. Most other applications fail permanently if the first connection attempt fails, i.e. they don't downgrade by itself and one has to enforce another version by some application specific settings.

Wrap the modal into a connected container and perform the async operation in here. This way you can reach both the dispatch to trigger actions and the onClose prop too. To reach dispatch from props, do not pass mapDispatchToProps function to connect.

class ModalContainer extends React.Component {
  handleDelete = () => {
    const { dispatch, onClose } = this.props;
    dispatch({type: 'DELETE_POST'});

    someAsyncOperation().then(() => {
      dispatch({type: 'DELETE_POST_SUCCESS'});
      onClose();
    })
  }

  render() {
    const { onClose } = this.props;
    return <Modal onClose={onClose} onSubmit={this.handleDelete} />
  }
}

export default connect(/* no map dispatch to props here! */)(ModalContainer);

The App where the modal is rendered and its visibility state is set:

class App extends React.Component {
  state = {
    isModalOpen: false
  }

  handleModalClose = () => this.setState({ isModalOpen: false });

  ...

  render(){
    return (
      ...
      <ModalContainer onClose={this.handleModalClose} />  
      ...
    )
  }

}

Can also be thought of as the number of ways of choosing pairs of nodes n choose 2 = n(n-1)/2. True if only any pair can have only one edge. Multiply by 2 otherwise

In my case i have a main.py that have dependencies with other files. After I build that app with py installer using this command:

pyinstaller --onefile --windowed main.py

I got the main.exe inside dist folder. I double clicked on this file, and I raised the error mentioned above. To fix this, I just copy the main.exe from dist directory to previous directory, which is the root directory of my main.py and the dependency files, and I got no error after run the main.exe.

Have you looked under Advanced Security Settings?

something like below image change permissions of folder to IIS_IUSRS

Watch out for the parentheses. As has been pointed out above, in Python 3, assert is still a statement, so by analogy with print(..), one may extrapolate the same to assert(..) or raise(..) but you shouldn't.

This is important because:

assert(2 + 2 == 5, "Houston we've got a problem")

won't work, unlike

assert 2 + 2 == 5, "Houston we've got a problem"

The reason the first one will not work is that bool( (False, "Houston we've got a problem") ) evaluates to True.

In the statement assert(False), these are just redundant parentheses around False, which evaluate to their contents. But with assert(False,) the parentheses are now a tuple, and a non-empty tuple evaluates to True in a boolean context.

There is simple answer in the official guide:

What does it not do?

It does not cause a full page reload when the browser URL is changed. To reload the page after changing the URL, use the lower-level API, $window.location.href.

I generally prefer hyphens with lower case, but one thing not yet mentioned is that sometimes it's nice to have the file name exactly match the name of a single module or instantiable function contained within.

For example, I have a revealing module declared with var knockoutUtilityModule = function() {...} within its own file named knockoutUtilityModule.js, although objectively I prefer knockout-utility-module.js.

Similarly, since I'm using a bundling mechanism to combine scripts, I've taken to defining instantiable functions (templated view models etc) each in their own file, C# style, for maintainability. For example, ProductDescriptorViewModel lives on its own inside ProductDescriptorViewModel.js (I use upper case for instantiable functions).

In npm v6+ npm uninstall <package_name> removes it both in folder node_modules and file package.json.

Be aware that this property isn't as useful as many people think it is. Just because your app is running on a Windows machine, for example, doesn't mean the file it's reading will be using Windows-style line separators. Many web pages contain a mixture of "\n" and "\r\n", having been cobbled together from disparate sources. When you're reading text as a series of logical lines, you should always look for all three of the major line-separator styles: Windows ("\r\n"), Unix/Linux/OSX ("\n") and pre-OSX Mac ("\r").

When you're writing text, you should be more concerned with how the file will be used than what platform you're running on. For example, if you expect people to read the file in Windows Notepad, you should use "\r\n" because it only recognizes the one kind of separator.

$('input[type="submit"]').click(function(){
$(this).css('color','red');
});

Use class, Demo:- http://jsfiddle.net/BX6Df/

   $('input[type="submit"]').click(function(){
          $(this).addClass('red');
});

if you want to toggle the color each click, you can try this:- http://jsfiddle.net/SMNks/

$('input[type="submit"]').click(function(){
  $(this).toggleClass('red');
});


.red
{
    background-color:red;
}

Updated answer for your comment.

http://jsfiddle.net/H2Xhw/

$('input[type="submit"]').click(function(){
    $('input[type="submit"].red').removeClass('red')
        $(this).addClass('red');
});

For me the better approach is that:

s.split('mango', 1)[-1]

...because if happens that occurrence is not in the string you'll get "IndexError: list index out of range".

Therefore -1 will not get any harm cause number of occurrences is already set to one.

The SDK agreement and App store guidelines have been changed (circa Sept 2010).

You can now probably use any compiled language that will compile to the same static ARM object file format as Xcode produces and that will link to (only) the public API's within Apple's frameworks and libraries. However, you can not use a JIT compiled language unless you pre-compile all object code before submission to Apple for review.

You can use any interpreted language, as long as you embed the interpreter, and do not allow the interpreter or the app to download and run any interpretable code other than code built into the app bundle before submission to Apple for review, or source code typed-in by the user.

Objective C and C will likely still be the most optimal programming language for anything requiring high performance and the latest API support (* see update below), as those are the languages for which Apple targets its iOS frameworks and tunes its ARM processor chipsets. Apple also supports the use of Javascript/HTML5 inside a UIWebView. Those are the only languages for which Apple has announced support. Anything else you will have to find support elsewhere.

But, if you really want, there are at least a half dozen BASIC interpreters now available in the iOS App store, so even "Stone Age" programming methodology is now allowed.

Added: (*) As of late 2014, one can also develop apps using Apple's new Swift programming language. As of early 2015, submitted binaries must include 64-bit (arm64) support.

If you've just added the select option to a form and you wish to trigger the change event, I've found a setTimeout is required otherwise jQuery doesn't pick up the newly added select box:

window.setTimeout(function() { jQuery('.languagedisplay').change();}, 1);

Try box-sizing. For the list:

height: 100%;
/* Presuming 10px header height */
padding-top: 10px;
/* Firefox */
-moz-box-sizing: border-box;
/* WebKit */
-webkit-box-sizing: border-box;
/* Standard */
box-sizing: border-box;

For the header:

position: absolute;
left: 0;
top: 0;
height: 10px;

Of course, the parent container should has something like:

position: relative;

I just wanted to add the fix I found for this issue. I'm not sure why this worked. I had the correct version of jstl (1.2) and also the correct version of servlet-api (2.5)

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <version>2.5</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
    <version>1.2</version>
</dependency>

I also had the correct address in my page as suggested in this thread, which is

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

What fixed this issue for me was removing the scope tag from my xml file in the pom for my jstl 1.2 dependency. Again not sure why that fixed it but just in case someone is doing the spring with JPA and Hibernate tutorial on pluralsight and has their pom setup this way, try removing the scope tag and see if that fixes it. Like I said it worked for me.

I think this clause is wrong:

if (!CGRectContainsPoint(aRect, activeField!.frame.origin))

While the activeField's origin may well be above the keyboard, the maxY might not...

I would create a 'max' point for the activeField and check if that is in the keyboard Rect.

Isn't this as simple as adding your git install to your Windows path?

E.g. Win+R rundll32.exe sysdm.cpl,EditEnvironmentVariables Edit...PATH appending your Mysysgit install path e.g. ;C:\Program Files (x86)\Git\bin. Re-run Cygwin and voila. As Cygwin automatically loads in the Windows environment, so too will your native install of Git.

You can use

 public static final String HELLO = "hello";

if you have many string constants, you can use external property file / simple "constant holder" class

In your specific case though it's probably easiest to use the -f flag to seq to get it to format the numbers as it outputs the list. For example:

for i in $(seq -f "%05g" 10 15)
do
  echo $i
done

will produce the following output:

00010
00011
00012
00013
00014
00015

More generally, bash has printf as a built-in so you can pad output with zeroes as follows:

$ i=99
$ printf "%05d\n" $i
00099

You can use the -v flag to store the output in another variable:

$ i=99
$ printf -v j "%05d" $i
$ echo $j
00099

Notice that printf supports a slightly different format to seq so you need to use %05d instead of %05g.

NOTE: The previous answers here aren't particularly useful if the BLOB is an arbitrary sequence of bytes; e.g. BINARY(16) to store 128-bit GUID or md5 checksum.

In that case, there currently is no editor preference -- though I have submitted a feature request now -- see that request for more detailed explanation.

[Until/unless that feature request is implemented], the solution is HEX function in a query: SELECT HEX(mybinarycolumn) FROM mytable.

An alternative is to use phpMyAdmin instead of MySQL Workbench - there hex is shown by default.

I changed css display and width property of print area

#printArea{_x000D_
    display:table;_x000D_
    width:100%;_x000D_
}

Go to Project properties.

Then 'Java Compiler' -> Check the box and "Enable project specific settings"

Uncheck the box to "Use Compliance from execution environment 'OSGi/Minimum-1.2' on the Java"

Then change the compiler compliance level to '1.5' and click Ok.

Rebuild it and your problem will be resolved.

You can use

[5,10].min 

or

[4,7].max

It's a method for Arrays.

Use vbCrLf or vbNewLine. It works with MessageBoxes and many other controls I tested.

Dim str As String
str = "First line" & vbCrLf & "Second line"
MsgBox(str)
str = "First line" & vbNewLine & "Second line"
MsgBox(str)

It will show two identical MessageBoxes with 2 lines.

If you are still getting that error after installing the 64 bit JRE, it means that the JVM running Gurobi package is still using the 32 bit JRE.

Check that you have updated the PATH and JAVA_HOME globally and in the command shell that you are using. (Maybe you just need to exit and restart it.)

Check that your command shell runs the right version of Java by running "java -version" and checking that it says it is a 64bit JRE.

If you are launching the example via a wrapper script / batch file, make sure that the script is using the right JRE. Modify as required ...

Keys must be comparable, but you haven't defined a suitable operator< for your custom class.

I got the same error after updating a referenced dll in a desktop executable project. The issue was as people here mentioned related an old reference and simple to fix but hasn’t been mentioned here, so I thought it might save other people’s time.

Anyway I updated dll A and got the error from another referenced dll let’s call it B here where dll A has a reference to dll B.

Updating dll B fixed the issue.

Manually creating a folder named 'npm' in the displayed path fixed the problem.

I tried the answers above but the generated script file was very large and I was having problems while importing the data. I ended up Detaching the database, then copying .mdf to my new machine, then Attaching it to my new version of SQL Server Management Studio.

I found instructions for how to do this on the Microsoft Website:
https://msdn.microsoft.com/en-us/library/ms187858.aspx

NOTE: After Detaching the database I found the .mdf file within this directory:
C:\Program Files\Microsoft SQL Server\

android:Layout_weight can be used when you don't attach a fix value to your width already like fill_parent etc.

Do something like this :

<Button>

Android:layout_width="0dp"
Android:layout_weight=1

-----other parameters
</Button>

You can do it like this:

#Just an example how the dictionary may look like
myDict = {'age': ['12'], 'address': ['34 Main Street, 212 First Avenue'],
      'firstName': ['Alan', 'Mary-Ann'], 'lastName': ['Stone', 'Lee']}

def search(values, searchFor):
    for k in values:
        for v in values[k]:
            if searchFor in v:
                return k
    return None

#Checking if string 'Mary' exists in dictionary value
print search(myDict, 'Mary') #prints firstName

allow_url_fopen is generally set to On. If it is not On, then you can try two things.

1. Create an .htaccess file and keep it in root folder ( sometimes it may need to place it one step back folder of the root) and paste this code there.

   php_value allow_url_fopen On
   

2. Create a php.ini file (for update server php5.ini) and keep it in root folder (sometimes it may need to place it one step back folder of the root) and paste the following code there:

   allow_url_fopen = On;
   

I have personally tested the above solutions; they worked for me.

Since @Etienne asked how to do this without melting the data (which in general is the preferred method, but I recognize there may be some cases where that is not possible), I present the following alternative.

Start with a subset of the original data:

datos <-
structure(list(fecha = structure(c(1317452400, 1317538800, 1317625200, 
1317711600, 1317798000, 1317884400, 1317970800, 1318057200, 1318143600, 
1318230000, 1318316400, 1318402800, 1318489200, 1318575600, 1318662000, 
1318748400, 1318834800, 1318921200, 1319007600, 1319094000), class = c("POSIXct", 
"POSIXt"), tzone = ""), TempMax = c(26.58, 27.78, 27.9, 27.44, 
30.9, 30.44, 27.57, 25.71, 25.98, 26.84, 33.58, 30.7, 31.3, 27.18, 
26.58, 26.18, 25.19, 24.19, 27.65, 23.92), TempMedia = c(22.88, 
22.87, 22.41, 21.63, 22.43, 22.29, 21.89, 20.52, 19.71, 20.73, 
23.51, 23.13, 22.95, 21.95, 21.91, 20.72, 20.45, 19.42, 19.97, 
19.61), TempMin = c(19.34, 19.14, 18.34, 17.49, 16.75, 16.75, 
16.88, 16.82, 14.82, 16.01, 16.88, 17.55, 16.75, 17.22, 19.01, 
16.95, 17.55, 15.21, 14.22, 16.42)), .Names = c("fecha", "TempMax", 
"TempMedia", "TempMin"), row.names = c(NA, 20L), class = "data.frame")

You can get the desired effect by (and this also cleans up the original plotting code):

ggplot(data = datos, aes(x = fecha)) +
  geom_line(aes(y = TempMax, colour = "TempMax")) +
  geom_line(aes(y = TempMedia, colour = "TempMedia")) +
  geom_line(aes(y = TempMin, colour = "TempMin")) +
  scale_colour_manual("", 
                      breaks = c("TempMax", "TempMedia", "TempMin"),
                      values = c("red", "green", "blue")) +
  xlab(" ") +
  scale_y_continuous("Temperatura (C)", limits = c(-10,40)) + 
  labs(title="TITULO")

The idea is that each line is given a color by mapping the colour aesthetic to a constant string. Choosing the string which is what you want to appear in the legend is the easiest. The fact that in this case it is the same as the name of the y variable being plotted is not significant; it could be any set of strings. It is very important that this is inside the aes call; you are creating a mapping to this "variable".

scale_colour_manual can now map these strings to the appropriate colors. The result is

In some cases, the mapping between the levels and colors needs to be made explicit by naming the values in the manual scale (thanks to @DaveRGP for pointing this out):

ggplot(data = datos, aes(x = fecha)) +
  geom_line(aes(y = TempMax, colour = "TempMax")) +
  geom_line(aes(y = TempMedia, colour = "TempMedia")) +
  geom_line(aes(y = TempMin, colour = "TempMin")) +
  scale_colour_manual("", 
                      values = c("TempMedia"="green", "TempMax"="red", 
                                 "TempMin"="blue")) +
  xlab(" ") +
  scale_y_continuous("Temperatura (C)", limits = c(-10,40)) + 
  labs(title="TITULO")

(giving the same figure as before). With named values, the breaks can be used to set the order in the legend and any order can be used in the values.

ggplot(data = datos, aes(x = fecha)) +
  geom_line(aes(y = TempMax, colour = "TempMax")) +
  geom_line(aes(y = TempMedia, colour = "TempMedia")) +
  geom_line(aes(y = TempMin, colour = "TempMin")) +
  scale_colour_manual("", 
                      breaks = c("TempMedia", "TempMax", "TempMin"),
                      values = c("TempMedia"="green", "TempMax"="red", 
                                 "TempMin"="blue")) +
  xlab(" ") +
  scale_y_continuous("Temperatura (C)", limits = c(-10,40)) + 
  labs(title="TITULO")

From the Javadoc:

Sometimes several tests need to share computationally expensive setup (like logging into a database). While this can compromise the independence of tests, sometimes it is a necessary optimization. Annotating a public static void no-arg method with @BeforeClass causes it to be run once before any of the test methods in the class. The @BeforeClass methods of superclasses will be run before those the current class.

Also, you might want to take a look at NetworkX

To me, the problem looks like you're sending "datetime('now')" as a string, rather than a value.

My thought is to find a way to grab the current date/time and send it to your database as a date/time value, or find a way to use SQLite's built-in (DATETIME('NOW')) parameter

Check out the anwsers at this SO.com question - they might lead you in the right direction.

Hopefully this helps!

I took the Ned Rockson's version and adjusted it to allow upwards scrolls as well.

var smoothScroll = function(elementId) {
  var MIN_PIXELS_PER_STEP = 16;
  var MAX_SCROLL_STEPS = 30;
  var target = document.getElementById(elementId);
  var scrollContainer = target;
  do {
    scrollContainer = scrollContainer.parentNode;
    if (!scrollContainer) return;
    scrollContainer.scrollTop += 1;
  } while (scrollContainer.scrollTop === 0);

  var targetY = 0;
  do {
    if (target === scrollContainer) break;
    targetY += target.offsetTop;
  } while (target = target.offsetParent);

  var pixelsPerStep = Math.max(MIN_PIXELS_PER_STEP,
    Math.abs(targetY - scrollContainer.scrollTop) / MAX_SCROLL_STEPS);

  var isUp = targetY < scrollContainer.scrollTop;

  var stepFunc = function() {
    if (isUp) {
      scrollContainer.scrollTop = Math.max(targetY, scrollContainer.scrollTop - pixelsPerStep);
      if (scrollContainer.scrollTop <= targetY) {
        return;
      }
    } else {
        scrollContainer.scrollTop = Math.min(targetY, scrollContainer.scrollTop + pixelsPerStep);

      if (scrollContainer.scrollTop >= targetY) {
        return;
      }
    }

    window.requestAnimationFrame(stepFunc);
  };

  window.requestAnimationFrame(stepFunc);
};

evict non ISO-8859-1 characters, will be replace by '?' (before send to a ISO-8859-1 DB by example):

utf8String = new String ( utf8String.getBytes(), "ISO-8859-1" );

3 approaches for creating a fullscreen iframe:

• Approach 1 - Viewport-percentage lengths

  In supported browsers, you can use viewport-percentage lengths such as height: 100vh.

  Where 100vh represents the height of the viewport, and likewise 100vw represents the width.

  Example Here

  _x000D_

  _x000D_

  body {_x000D_
      margin: 0;            /* Reset default margin */_x000D_
  }_x000D_
  iframe {_x000D_
      display: block;       /* iframes are inline by default */_x000D_
      background: #000;_x000D_
      border: none;         /* Reset default border */_x000D_
      height: 100vh;        /* Viewport-relative units */_x000D_
      width: 100vw;_x000D_
  }

  _x000D_

  <iframe></iframe>

  _x000D_

  _x000D_
  _x000D_

• Approach 2 - Fixed positioning

  This approach is fairly straight-forward. Just set the positioning of the fixed element and add a height/width of 100%.

  Example Here

  _x000D_

  _x000D_

  iframe {_x000D_
      position: fixed;_x000D_
      background: #000;_x000D_
      border: none;_x000D_
      top: 0; right: 0;_x000D_
      bottom: 0; left: 0;_x000D_
      width: 100%;_x000D_
      height: 100%;_x000D_
  }

  _x000D_

  <iframe></iframe>

  _x000D_

  _x000D_
  _x000D_

• Approach 3

  For this last method, just set the height of the body/html/iframe elements to 100%.

  Example Here

  _x000D_

  _x000D_

  html, body {_x000D_
      height: 100%;_x000D_
      margin: 0;         /* Reset default margin on the body element */_x000D_
  }_x000D_
  iframe {_x000D_
      display: block;       /* iframes are inline by default */_x000D_
      background: #000;_x000D_
      border: none;         /* Reset default border */_x000D_
      width: 100%;_x000D_
      height: 100%;_x000D_
  }

  _x000D_

  <iframe></iframe>

  _x000D_

  _x000D_
  _x000D_

I had let this go for a good while but revisited it later. Since this question is viewed regularly. This is eventually what I ended up using that worked for me.

define("DOC_ROOT","/path/to/html");
//username and password of account
$username = trim($values["email"]);
$password = trim($values["password"]);

//set the directory for the cookie using defined document root var
$path = DOC_ROOT."/ctemp";
//build a unique path with every request to store. the info per user with custom func. I used this function to build unique paths based on member ID, that was for my use case. It can be a regular dir.
//$path = build_unique_path($path); // this was for my use case

//login form action url
$url="https://www.example.com/login/action"; 
$postinfo = "email=".$username."&password=".$password;

$cookie_file_path = $path."/cookie.txt";

$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_NOBODY, false);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);

curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file_path);
//set the cookie the site has for certain features, this is optional
curl_setopt($ch, CURLOPT_COOKIE, "cookiename=0");
curl_setopt($ch, CURLOPT_USERAGENT,
    "Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_REFERER, $_SERVER['REQUEST_URI']);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postinfo);
curl_exec($ch);

//page with the content I want to grab
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/page/");
//do stuff with the info with DomDocument() etc
$html = curl_exec($ch);
curl_close($ch);

Update: This code was never meant to be a copy and paste. It was to show how I used it for my specific use case. You should adapt it to your code as needed. Such as directories, vars etc

Here is solution for dynamic queries.

For example if you have more tables with different suffix:

dbo.SOMETHINGTABLE_ONE, dbo.SOMETHINGTABLE_TWO

Code:

DECLARE @INDEX AS NVARCHAR(20)
DECLARE @CheckVALUE AS NVARCHAR(max) = 'SELECT COUNT(SOMETHING) FROM 
dbo.SOMETHINGTABLE_'+@INDEX+''
DECLARE @tempTable Table (TempVALUE int)
DECLARE @RESULTVAL INT

INSERT INTO @tempTable
    EXEC sp_executesql @CheckVALUE

SET @RESULTVAL = (SELECT * FROM @tempTable)

DELETE @tempTable

SELECT @RESULTVAL 

AdventureWorksDataContext db = new AdventureWorksDataContext();
db.Log = Console.Out;

// Get hte first customer record
Customer c = from cust in db.Customers select cust where id = 5;
Console.WriteLine(c.CustomerType);
c.CustomerType = 'I';
db.SubmitChanges(); // Save the changes away

import java.lang.StringBuilder;

public class Program {
    public static void main(String[] args) {

    // Create a new StringBuilder.
    StringBuilder builder = new StringBuilder();

    // Loop and append values.
    for (int i = 0; i < 5; i++) {
        builder.append("abc ");
    }
    // Convert to string.
    String result = builder.toString();

    // Print result.
    System.out.println(result);
    }
}

Create a .c file containing just the line:

_MSC_VER

or

CompilerVersion=_MSC_VER

then pre-process with

cl /nologo /EP <filename>.c

It is easy to parse the output.

Basically I use Fiddler or Postman for testing API's.

In fiddler, in request header you need to specify instead of xml, html you need to change it to json. Eg: Accept: application/json. That should do the job.

use the limit clausule, with the offset to choose the row number -1 so if u wanna get the number 8 row so use:

limit 1 offset 7

You can also build up a list of lists and convert it to a dataframe -

import pandas as pd

columns = ['i','double','square']
rows = []

for i in range(6):
    row = [i, i*2, i*i]
    rows.append(row)

df = pd.DataFrame(rows, columns=columns)

giving

    i   double  square
0   0   0   0
1   1   2   1
2   2   4   4
3   3   6   9
4   4   8   16
5   5   10  25

So many questions here. I see at least two, maybe three:

• What does pop(a,b) do?/Why are there a second argument?
• What is *args being used for?

The first question is trivially answered in the Python Standard Library reference:

pop(key[, default])

If key is in the dictionary, remove it and return its value, else return default. If default is not given and key is not in the dictionary, a KeyError is raised.

The second question is covered in the Python Language Reference:

If the form “*identifier” is present, it is initialized to a tuple receiving any excess positional parameters, defaulting to the empty tuple. If the form “**identifier” is present, it is initialized to a new dictionary receiving any excess keyword arguments, defaulting to a new empty dictionary.

In other words, the pop function takes at least two arguments. The first two get assigned the names self and key; and the rest are stuffed into a tuple called args.

What's happening on the next line when *args is passed along in the call to self.data.pop is the inverse of this - the tuple *args is expanded to of positional parameters which get passed along. This is explained in the Python Language Reference:

If the syntax *expression appears in the function call, expression must evaluate to a sequence. Elements from this sequence are treated as if they were additional positional arguments

In short, a.pop() wants to be flexible and accept any number of positional parameters, so that it can pass this unknown number of positional parameters on to self.data.pop().

This gives you flexibility; data happens to be a dict right now, and so self.data.pop() takes either one or two parameters; but if you changed data to be a type which took 19 parameters for a call to self.data.pop() you wouldn't have to change class a at all. You'd still have to change any code that called a.pop() to pass the required 19 parameters though.

$date = mktime( 0, 0, 0, 2, 1, 2014 );

echo strftime( '%d %B %Y', strtotime( '+1 month', $date ) );

Given the proliferation of different ways to read an Excel file in R and the plethora of answers here, I thought I'd try to shed some light on which of the options mentioned here perform the best (in a few simple situations).

I myself have been using xlsx since I started using R, for inertia if nothing else, and I recently noticed there doesn't seem to be any objective information about which package works better.

Any benchmarking exercise is fraught with difficulties as some packages are sure to handle certain situations better than others, and a waterfall of other caveats.

That said, I'm using a (reproducible) data set that I think is in a pretty common format (8 string fields, 3 numeric, 1 integer, 3 dates):

set.seed(51423)
data.frame(
  str1 = sample(sprintf("%010d", 1:NN)), #ID field 1
  str2 = sample(sprintf("%09d", 1:NN)),  #ID field 2
  #varying length string field--think names/addresses, etc.
  str3 = 
    replicate(NN, paste0(sample(LETTERS, sample(10:30, 1L), TRUE),
                         collapse = "")),
  #factor-like string field with 50 "levels"
  str4 = sprintf("%05d", sample(sample(1e5, 50L), NN, TRUE)),
  #factor-like string field with 17 levels, varying length
  str5 = 
    sample(replicate(17L, paste0(sample(LETTERS, sample(15:25, 1L), TRUE),
                                 collapse = "")), NN, TRUE),
  #lognormally distributed numeric
  num1 = round(exp(rnorm(NN, mean = 6.5, sd = 1.5)), 2L),
  #3 binary strings
  str6 = sample(c("Y","N"), NN, TRUE),
  str7 = sample(c("M","F"), NN, TRUE),
  str8 = sample(c("B","W"), NN, TRUE),
  #right-skewed integer
  int1 = ceiling(rexp(NN)),
  #dates by month
  dat1 = 
    sample(seq(from = as.Date("2005-12-31"), 
               to = as.Date("2015-12-31"), by = "month"),
           NN, TRUE),
  dat2 = 
    sample(seq(from = as.Date("2005-12-31"), 
               to = as.Date("2015-12-31"), by = "month"),
           NN, TRUE),
  num2 = round(exp(rnorm(NN, mean = 6, sd = 1.5)), 2L),
  #date by day
  dat3 = 
    sample(seq(from = as.Date("2015-06-01"), 
               to = as.Date("2015-07-15"), by = "day"),
           NN, TRUE),
  #lognormal numeric that can be positive or negative
  num3 = 
    (-1) ^ sample(2, NN, TRUE) * round(exp(rnorm(NN, mean = 6, sd = 1.5)), 2L)
)

I then wrote this to csv and opened in LibreOffice and saved it as an .xlsx file, then benchmarked 4 of the packages mentioned in this thread: xlsx, openxlsx, readxl, and gdata, using the default options (I also tried a version of whether or not I specify column types, but this didn't change the rankings).

I'm excluding RODBC because I'm on Linux; XLConnect because it seems its primary purpose is not reading in single Excel sheets but importing entire Excel workbooks, so to put its horse in the race on only its reading capabilities seems unfair; and xlsReadWrite because it is no longer compatible with my version of R (seems to have been phased out).

I then ran benchmarks with NN=1000L and NN=25000L (resetting the seed before each declaration of the data.frame above) to allow for differences with respect to Excel file size. gc is primarily for xlsx, which I've found at times can create memory clogs. Without further ado, here are the results I found:

So readxl is the winner, with openxlsx competitive and gdata a clear loser. Taking each measure relative to the column minimum:

#       expr   min    lq  mean median    uq   max
# 1     xlsx  1.59  1.62  1.62   1.63  1.63  1.65
# 2 openxlsx  1.17  1.16  1.15   1.16  1.14  1.19
# 3   readxl  1.00  1.00  1.00   1.00  1.00  1.00
# 4    gdata 16.43 16.62 15.77  16.67 16.25 11.31

We see my own favorite, xlsx is 60% slower than readxl.

25,000-Row Excel File

Due to the amount of time it takes, I only did 20 repetitions on the larger file, otherwise the commands were identical. Here's the raw data:

# Unit: milliseconds
#      expr        min         lq       mean     median         uq        max neval
#      xlsx  4451.9553  4539.4599  4738.6366  4762.1768  4941.2331  5091.0057    20
#  openxlsx   962.1579   981.0613   988.5006   986.1091   992.6017  1040.4158    20
#    readxl   341.0006   344.8904   347.0779   346.4518   348.9273   360.1808    20
#     gdata 43860.4013 44375.6340 44848.7797 44991.2208 45251.4441 45652.0826    20

Here's the relative data:

#       expr    min     lq   mean median     uq    max
# 1     xlsx  13.06  13.16  13.65  13.75  14.16  14.13
# 2 openxlsx   2.82   2.84   2.85   2.85   2.84   2.89
# 3   readxl   1.00   1.00   1.00   1.00   1.00   1.00
# 4    gdata 128.62 128.67 129.22 129.86 129.69 126.75

So readxl is the clear winner when it comes to speed. gdata better have something else going for it, as it's painfully slow in reading Excel files, and this problem is only exacerbated for larger tables.

Two draws of openxlsx are 1) its extensive other methods (readxl is designed to do only one thing, which is probably part of why it's so fast), especially its write.xlsx function, and 2) (more of a drawback for readxl) the col_types argument in readxl only (as of this writing) accepts some nonstandard R: "text" instead of "character" and "date" instead of "Date".

This happened to me when I was on develop branch and my master branch is not with latest update.

So when I tried to git push from develop branch I had that error.

I fixed it by switching to master branch, git pull, then go back to develop branch and git push.

$ git fetch && git checkout master
$ git pull
$ git fetch && git checkout develop
$ git push

Six years on, this is still at the top for some searches. Things have changed a lot since then. Now the defacto standard is more or less to use Volley and the NetworkImageView which takes care of the heavy lifting for you.

Assuming that you already have your Apaters, Loaders and ListFragments setup properly, this official google tutorial explains how to use NetworkImageView to load the images. Images are automatically loaded in a background thread and the view updated on the UI thread. It even supports caching.

Docker treats lines that begin with # as a comment, unless the line is a valid parser directive. A # marker anywhere else in a line is treated as an argument.

example code:

# this line is a comment

RUN echo 'we are running some # of cool things'

Output:

we are running some # of cool things

The following works for me and tested on Ubuntu 14.04. It is a one liner that does not require any user input.

sudo useradd -p $(openssl passwd -1 $PASS) $USERNAME

Taken from @Tralemonkey

you can use delete operator to delete property by it's name

delete objectExpression.property

or iterate through the object and find the value you need and delete it:

for(prop in Obj){
   if(Obj.hasOwnProperty(prop)){
      if(Obj[prop] === 'myValue'){
        delete Obj[prop];
      }
   }
}

git checkout .

i always use this command to replace my local changes with repository changes. git checkout space dot.

If you are able to run a script, here is what I did for a similar situation:

Using a dictionary/hashMap (associative array) and variables for the sed command, we can loop through the array to replace several strings. Including a wildcard in the name_pattern will allow to replace in-place in files with a pattern (this could be something like name_pattern='File*.txt' ) in a specific directory (source_dir). All the changes are written in the logfile in the destin_dir

#!/bin/bash
source_dir=source_path
destin_dir=destin_path
logfile='sedOutput.txt'
name_pattern='File.txt'

echo "--Begin $(date)--" | tee -a $destin_dir/$logfile
echo "Source_DIR=$source_dir destin_DIR=$destin_dir "

declare -A pairs=( 
    ['WHAT1']='FOR1'
    ['OTHER_string_to replace']='string replaced'
)

for i in "${!pairs[@]}"; do
    j=${pairs[$i]}
    echo "[$i]=$j"
    replace_what=$i
    replace_for=$j
    echo " "
    echo "Replace: $replace_what for: $replace_for"
    find $source_dir -name $name_pattern | xargs sed -i "s/$replace_what/$replace_for/g" 
    find $source_dir -name $name_pattern | xargs -I{} grep -n "$replace_for" {} /dev/null | tee -a $destin_dir/$logfile
done

echo " "
echo "----End $(date)---" | tee -a $destin_dir/$logfile

First, the pairs array is declared, each pair is a replacement string, then WHAT1 will be replaced for FOR1 and OTHER_string_to replace will be replaced for string replaced in the file File.txt. In the loop the array is read, the first member of the pair is retrieved as replace_what=$i and the second as replace_for=$j. The find command searches in the directory the filename (that may contain a wildcard) and the sed -i command replaces in the same file(s) what was previously defined. Finally I added a grep redirected to the logfile to log the changes made in the file(s).

This worked for me in GNU Bash 4.3 sed 4.2.2 and based upon VasyaNovikov's answer for Loop over tuples in bash.

Most of the given examples assume that for the test range [$a..$b], $a <= $b, i.e. the range extremes are in lower - higher order and most assume that all are integer numbers.
But I needed a function to test if $n was between $a and $b, as described here:

Check if $n is between $a and $b even if:
    $a < $b  
    $a > $b
    $a = $b

All numbers can be real, not only integer.

There is an easy way to test.
I base the test it in the fact that ($n-$a) and ($n-$b) have different signs when $n is between $a and $b, and the same sign when $n is outside the $a..$b range.
This function is valid for testing increasing, decreasing, positive and negative numbers, not limited to test only integer numbers.

function between($n, $a, $b)
{
    return (($a==$n)&&($b==$n))? true : ($n-$a)*($n-$b)<0;
}

The following command will save your password in memory for some time (for Git 1.7.10 or newer).

$ git config --global credential.helper cache
# Set git to use the credential memory cache

$ git config --global credential.helper 'cache --timeout=3600'
# Set the cache to timeout after one hour (setting is in seconds)

Here's one way...

>>> s = '2134'
>>> def swap(c, i, j):
...  c = list(c)
...  c[i], c[j] = c[j], c[i]
...  return ''.join(c)
...
>>> swap(s, 0, 1)
'1234'
>>>

Update
While what I write below is true as a general answer about shared libraries, I think the most frequent cause of these sorts of message is because you've installed a package, but not installed the "-dev" version of that package.

Well, it's not lying - there is no libpthread_rt.so.1 in that listing. You probably need to re-configure and re-build it so that it depends on the library you have, or install whatever provides libpthread_rt.so.1.

Generally, the numbers after the .so are version numbers, and you'll often find that they are symlinks to each other, so if you have version 1.1 of libfoo.so, you'll have a real file libfoo.so.1.0, and symlinks foo.so and foo.so.1 pointing to the libfoo.so.1.0. And if you install version 1.1 without removing the other one, you'll have a libfoo.so.1.1, and libfoo.so.1 and libfoo.so will now point to the new one, but any code that requires that exact version can use the libfoo.so.1.0 file. Code that just relies on the version 1 API, but doesn't care if it's 1.0 or 1.1 will specify libfoo.so.1. As orip pointed out in the comments, this is explained well at http://tldp.org/HOWTO/Program-Library-HOWTO/shared-libraries.html.

In your case, you might get away with symlinking libpthread_rt.so.1 to libpthread_rt.so. No guarantees that it won't break your code and eat your TV dinners, though.

i believe you can use

CREATE TABLE test (
  id INTEGER PRIMARY KEY AUTOINCREMENT,
  t TIMESTAMP
  DEFAULT CURRENT_TIMESTAMP
);

as of version 3.1 (source)

The output in your first printline is using your formatter. The output in your second (the date created from your parsed string) is output using Date#toString which formats according to its own rules. That is, you're not using a formatter.

The rules are as per what you're seeing and described here: http://docs.oracle.com/javase/6/docs/api/java/util/Date.html#toString()
