You could use GROUP_CONCAT aggregated function to get all years into a single column, grouped by id and ordered by rate:

SELECT   id, GROUP_CONCAT(year ORDER BY rate DESC) grouped_year
FROM     yourtable
GROUP BY id

Result:

-----------------------------------------------------------
|  ID | GROUPED_YEAR                                      |
-----------------------------------------------------------
| p01 | 2006,2003,2008,2001,2007,2009,2002,2004,2005,2000 |
| p02 | 2001,2004,2002,2003,2000,2006,2007                |
-----------------------------------------------------------

And then you could use FIND_IN_SET, that returns the position of the first argument inside the second one, eg.

SELECT FIND_IN_SET('2006', '2006,2003,2008,2001,2007,2009,2002,2004,2005,2000');
1

SELECT FIND_IN_SET('2009', '2006,2003,2008,2001,2007,2009,2002,2004,2005,2000');
6

Using a combination of GROUP_CONCAT and FIND_IN_SET, and filtering by the position returned by find_in_set, you could then use this query that returns only the first 5 years for every id:

SELECT
  yourtable.*
FROM
  yourtable INNER JOIN (
    SELECT
      id,
      GROUP_CONCAT(year ORDER BY rate DESC) grouped_year
    FROM
      yourtable
    GROUP BY id) group_max
  ON yourtable.id = group_max.id
     AND FIND_IN_SET(year, grouped_year) BETWEEN 1 AND 5
ORDER BY
  yourtable.id, yourtable.year DESC;

Please see fiddle here.

Please note that if more than one row can have the same rate, you should consider using GROUP_CONCAT(DISTINCT rate ORDER BY rate) on the rate column instead of the year column.

The maximum length of the string returned by GROUP_CONCAT is limited, so this works well if you need to select a few records for every group.

Here is the Fluent API syntax.

class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string FullName {

            return this.FirstName + " " + this.LastName;
        }
    }
}

class PersonViewModel : Person

    public bool UpdateProfile { get; set; }
}


protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
    // ignore a type that is not mapped to a database table
    modelBuilder.Ignore<PersonViewModel>();

    // ignore a property that is not mapped to a database column
    modelBuilder.Entity<Person>()
        .Ignore(p => p.FullName);

}

If you don't want to repeat the list twice (as per @J W's answer), then put the updates in a table variable and use a JOIN in the UPDATE:

declare @ToDo table (FromName varchar(10), ToName varchar(10))
insert into @ToDo(FromName,ToName) values
 ('AAA','BBB'),
 ('CCC','DDD'),
 ('EEE','FFF')

update ts set LastName = ToName
from dbo.TestStudents ts
       inner join
     @ToDo t
       on
         ts.LastName = t.FromName

When I read this, it sounded like a tough challenge so I decided to figure out a way. What I came up with was CRAAAAZY but it totally works.

First, I tried defining the class in an immediate function so you'd have access to some of the private properties of that function. This works and allows you to get some private data, however, if you try to set the private data you'll soon find that all the objects will share the same value.

var SharedPrivateClass = (function() { // use immediate function_x000D_
    // our private data_x000D_
    var private = "Default";_x000D_
_x000D_
    // create the constructor_x000D_
    function SharedPrivateClass() {}_x000D_
_x000D_
    // add to the prototype_x000D_
    SharedPrivateClass.prototype.getPrivate = function() {_x000D_
        // It has access to private vars from the immediate function!_x000D_
        return private;_x000D_
    };_x000D_
_x000D_
    SharedPrivateClass.prototype.setPrivate = function(value) {_x000D_
        private = value;_x000D_
    };_x000D_
_x000D_
    return SharedPrivateClass;_x000D_
})();_x000D_
_x000D_
var a = new SharedPrivateClass();_x000D_
console.log("a:", a.getPrivate()); // "a: Default"_x000D_
_x000D_
var b = new SharedPrivateClass();_x000D_
console.log("b:", b.getPrivate()); // "b: Default"_x000D_
_x000D_
a.setPrivate("foo"); // a Sets private to "foo"_x000D_
console.log("a:", a.getPrivate()); // "a: foo"_x000D_
console.log("b:", b.getPrivate()); // oh no, b.getPrivate() is "foo"!_x000D_
_x000D_
console.log(a.hasOwnProperty("getPrivate")); // false. belongs to the prototype_x000D_
console.log(a.private); // undefined_x000D_
_x000D_
// getPrivate() is only created once and instanceof still works_x000D_
console.log(a.getPrivate === b.getPrivate);_x000D_
console.log(a instanceof SharedPrivateClass);_x000D_
console.log(b instanceof SharedPrivateClass);

There are plenty of cases where this would be adequate like if you wanted to have constant values like event names that get shared between instances. But essentially, they act like private static variables.

If you absolutely need access to variables in a private namespace from within your methods defined on the prototype, you can try this pattern.

var PrivateNamespaceClass = (function() { // immediate function_x000D_
    var instance = 0, // counts the number of instances_x000D_
        defaultName = "Default Name",  _x000D_
        p = []; // an array of private objects_x000D_
_x000D_
    // create the constructor_x000D_
    function PrivateNamespaceClass() {_x000D_
        // Increment the instance count and save it to the instance. _x000D_
        // This will become your key to your private space._x000D_
        this.i = instance++; _x000D_
        _x000D_
        // Create a new object in the private space._x000D_
        p[this.i] = {};_x000D_
        // Define properties or methods in the private space._x000D_
        p[this.i].name = defaultName;_x000D_
        _x000D_
        console.log("New instance " + this.i);        _x000D_
    }_x000D_
_x000D_
    PrivateNamespaceClass.prototype.getPrivateName = function() {_x000D_
        // It has access to the private space and it's children!_x000D_
        return p[this.i].name;_x000D_
    };_x000D_
    PrivateNamespaceClass.prototype.setPrivateName = function(value) {_x000D_
        // Because you use the instance number assigned to the object (this.i)_x000D_
        // as a key, the values set will not change in other instances._x000D_
        p[this.i].name = value;_x000D_
        return "Set " + p[this.i].name;_x000D_
    };_x000D_
_x000D_
    return PrivateNamespaceClass;_x000D_
})();_x000D_
_x000D_
var a = new PrivateNamespaceClass();_x000D_
console.log(a.getPrivateName()); // Default Name_x000D_
_x000D_
var b = new PrivateNamespaceClass();_x000D_
console.log(b.getPrivateName()); // Default Name_x000D_
_x000D_
console.log(a.setPrivateName("A"));_x000D_
console.log(b.setPrivateName("B"));_x000D_
console.log(a.getPrivateName()); // A_x000D_
console.log(b.getPrivateName()); // B_x000D_
_x000D_
// private objects are not accessible outside the PrivateNamespaceClass function_x000D_
console.log(a.p);_x000D_
_x000D_
// the prototype functions are not re-created for each instance_x000D_
// and instanceof still works_x000D_
console.log(a.getPrivateName === b.getPrivateName);_x000D_
console.log(a instanceof PrivateNamespaceClass);_x000D_
console.log(b instanceof PrivateNamespaceClass);

I'd love some feedback from anyone who sees an error with this way of doing it.

I have similar problem. Spring 4 and Tomcat 8. I solve the problem with Spring configuration

<bean id="dataSource" class="org.apache.tomcat.jdbc.pool.DataSource" destroy-method="close">
    <property name="initialSize" value="10" />
    <property name="maxActive" value="25" />
    <property name="maxIdle" value="20" />
    <property name="minIdle" value="10" />
     ...
    <property name="testOnBorrow" value="true" />
    <property name="validationQuery" value="SELECT 1" />
 </bean>

I have tested. It works well! This two line does everything in order to reconnect to database:

<property name="testOnBorrow" value="true" />
<property name="validationQuery" value="SELECT 1" />

TL/DR

This solution was tested using Python 3.6

To strip all spaces from a string in Python3 you can use the following function:

def remove_spaces(in_string: str):
    return in_string.translate(str.maketrans({' ': ''})

To remove any whitespace characters (' \t\n\r\x0b\x0c') you can use the following function:

import string
def remove_whitespace(in_string: str):
    return in_string.translate(str.maketrans(dict.fromkeys(string.whitespace)))

Explanation

Python's str.translate method is a built-in class method of str, it takes a table and returns a copy of the string with each character mapped through the passed translation table. Full documentation for str.translate

To create the translation table str.maketrans is used. This method is another built-in class method of str. Here we use it with only one parameter, in this case a dictionary, where the keys are the characters to be replaced mapped to values with the characters replacement value. It returns a translation table for use with str.translate. Full documentation for str.maketrans

The string module in python contains some common string operations and constants. string.whitespace is a constant which returns a string containing all ASCII characters that are considered whitespace. This includes the characters space, tab, linefeed, return, formfeed, and vertical tab.Full documentation for string

In the second function dict.fromkeys is used to create a dictionary where the keys are the characters in the string returned by string.whitespace each with value None. Full documentation for dict.fromkeys

This should do it:

<StackPanel>
    <TextBox x:Name="TheTextBox" />
    <Button Content="Click Me">
        <Button.Style>
            <Style TargetType="Button">
                <Setter Property="IsEnabled" Value="True" />
                <Style.Triggers>
                    <DataTrigger Binding="{Binding Text, ElementName=TheTextBox}" Value="">
                        <Setter Property="IsEnabled" Value="False" />
                    </DataTrigger>
                </Style.Triggers>
            </Style>
        </Button.Style>
    </Button>
</StackPanel>

Finally, solved the problem above. I was receiving errors

Since I have not added WKWebView object on the view as a subview and tried to call -loadHTMLString:baseURL: on the top of it. And only after it was successfully loaded I was adding it to view's subviews - which was totally wrong. The correct solution for my problem is:

1. Add WKWebView object to view's subviews array

2. Call -loadHTMLString:baseURL: for recently added WKWebView

First off, it is perfectly feasible to use R successfully for years and not need to know the answer to this question. R handles the differences between the (usual) numerics and integers for you in the background.

> is.numeric(1)

[1] TRUE

> is.integer(1)

[1] FALSE

> is.numeric(1L)

[1] TRUE

> is.integer(1L)

[1] TRUE

(Putting capital 'L' after an integer forces it to be stored as an integer.)

As you can see "integer" is a subset of "numeric".

> .Machine$integer.max

[1] 2147483647

> .Machine$double.xmax

[1] 1.797693e+308

Integers only go to a little more than 2 billion, while the other numerics can be much bigger. They can be bigger because they are stored as double precision floating point numbers. This means that the number is stored in two pieces: the exponent (like 308 above, except in base 2 rather than base 10), and the "significand" (like 1.797693 above).

Note that 'is.integer' is not a test of whether you have a whole number, but a test of how the data are stored.

One thing to watch out for is that the colon operator, :, will return integers if the start and end points are whole numbers. For example, 1:5 creates an integer vector of numbers from 1 to 5. You don't need to append the letter L.

> class(1:5)
[1] "integer"

Get all the checked checkbox value in an array - one liner

If you are looking out at performance, you could have a look at the java.nio.* packages - those are supposedly faster than java.io.*

You can install Kafkacat tool on your machine

For example on Ubuntu You can install it using

apt-get install kafkacat

once kafkacat is installed then you can use following command to connect it

kafkacat -b <your-ip-address>:<kafka-port> -t test-topic

• Replace <your-ip-address> with your machine ip
• <kafka-port> can be replaced by the port on which kafka is running. Normally it is 9092

once you run the above command and if kafkacat is able to make the connection then it means that kafka is up and running

I want to know the time to brute force for when the password is a dictionary word and also when it is not a dictionary word.

Dictionary password

Ballpark figure: there are about 1,000,000 English words, and if a hacker can compute about 10,000 SHA-512 hashes a second (update: see comment by CodesInChaos, this estimate is very low), 1,000,000 / 10,000 = 100 seconds. So it would take just over a minute to crack a single-word dictionary password for a single user. If the user concatenates two dictionary words, you're in the area of a few days, but still very possible if the attacker is cares enough. More than that and it starts getting tough.

Random password

If the password is a truly random sequence of alpha-numeric characters, upper and lower case, then the number of possible passwords of length N is 60^N (there are 60 possible characters). We'll do the calculation the other direction this time; we'll ask: What length of password could we crack given a specific length of time? Just use this formula:

N = Log60(t * 10,000) where t is the time spent calculating hashes in seconds (again assuming 10,000 hashes a second).

1 minute:    3.2
5 minute:    3.6
30 minutes:  4.1
2 hours:     4.4
3 days:      5.2

So given a 3 days we'd be able to crack the password if it's 5 characters long.

This is all very ball-park, but you get the idea. Update: see comment below, it's actually possible to crack much longer passwords than this.

What's going on here?

Let's clear up some misconceptions:

• The salt doesn't make it slower to calculate hashes, it just means they have to crack each user's password individually, and pre-computed hash tables (buzz-word: rainbow tables) are made completely useless. If you don't have a precomputed hash-table, and you're only cracking one password hash, salting doesn't make any difference.

• SHA-512 isn't designed to be hard to brute-force. Better hashing algorithms like BCrypt, PBKDF2 or SCrypt can be configured to take much longer to compute, and an average computer might only be able to compute 10-20 hashes a second. Read This excellent answer about password hashing if you haven't already.

• update: As written in the comment by CodesInChaos, even high entropy passwords (around 10 characters) could be bruteforced if using the right hardware to calculate SHA-512 hashes.

Notes on accepted answer:

The accepted answer as of September 2014 is incorrect and dangerously wrong:

In your case, breaking the hash algorithm is equivalent to finding a collision in the hash algorithm. That means you don't need to find the password itself (which would be a preimage attack)... Finding a collision using a birthday attack takes O(2^n/2) time, where n is the output length of the hash function in bits.

The birthday attack is completely irrelevant to cracking a given hash. And this is in fact a perfect example of a preimage attack. That formula and the next couple of paragraphs result in dangerously high and completely meaningless values for an attack time. As demonstrated above it's perfectly possible to crack salted dictionary passwords in minutes.

The low entropy of typical passwords makes it possible that there is a relatively high chance of one of your users using a password from a relatively small database of common passwords...

That's why generally hashing and salting alone is not enough, you need to install other safety mechanisms as well. You should use an artificially slowed down entropy-enducing method such as PBKDF2 described in PKCS#5...

Yes, please use an algorithm that is slow to compute, but what is "entropy-enducing"? Putting a low entropy password through a hash doesn't increase entropy. It should preserve entropy, but you can't make a rubbish password better with a hash, it doesn't work like that. A weak password put through PBKDF2 is still a weak password.

You have to do this:

class Bar : public Foo
{
    // ...
}

The default inheritance type of a class in C++ is private, so any public and protected members from the base class are limited to private. struct inheritance on the other hand is public by default.

In the Latest Version of Android Studio, the options for Auto-Import is enabled by default, so kudos no need to worry about that.

On Windows: If for some reasons auto-import is not enable you can go to settings by typing shortcut: Ctrl+Alt+S.

In the Search term just type 'Auto-Import' and then select 'Add unambiguous Imports on the fly' and click Ok.

That's it. You are Done. SnapShot of Auto_import

According to the documentation, the static method UUID.randomUUID() generates a type 4 UUID.

This means that six bits are used for some type information and the remaining 122 bits are assigned randomly.

The six non-random bits are distributed with four in the most significant half of the UUID and two in the least significant half. So the most significant half of your UUID contains 60 bits of randomness, which means you on average need to generate 2^30 UUIDs to get a collision (compared to 2^61 for the full UUID).

So I would say that you are rather safe. Note, however that this is absolutely not true for other types of UUIDs, as Carl Seleborg mentions.

Incidentally, you would be slightly better off by using the least significant half of the UUID (or just generating a random long using SecureRandom).

if(displayit){
  login_div.Style["display"]="inline"; //the default display mode
}else{
  login_div.Style["display"]="none";
}

Adding this code into Page_Load should work. (if doing it at Page_Init you'll have to contend with viewstate changing what you put in it)

Yes. Or, rather, no.

Er, I mean, it doesn't matter. Use the one that makes sense for your particular project. PX and EM or both equally valid but will behave a bit different depending on your overall page's CSS architecture.

UPDATE:

To clarify, I'm stating that usually it likely doesn't matter which you use. At times, you may specifically want to choose one over the other. EMs are nice if you can start from scratch and want to use a base font size and make everything relative to that.

PXs are often needed when you're retrofitting a redesign onto an existing code base and need the specificity of px to prevent bad nesting issues.

The most you can get is:

select#xyz {
   border:0px;
   outline:0px;
}

You cannot style it completely, but you can try something like

select#xyz {
  -webkit-appearance: button;
  -webkit-border-radius: 2px;
  -webkit-box-shadow: 0px 1px 3px rgba(0, 0, 0, 0.1);
  -webkit-padding-end: 20px;
  -webkit-padding-start: 2px;
  -webkit-user-select: none;
  background-image: url(../images/select-arrow.png), 
    -webkit-linear-gradient(#FAFAFA, #F4F4F4 40%, #E5E5E5);
  background-position: center right;
  background-repeat: no-repeat;
  border: 1px solid #AAA;
  color: #555;
  font-size: inherit;
  margin: 0;
  overflow: hidden;
  padding-top: 2px;
  padding-bottom: 2px;
  text-overflow: ellipsis;
  white-space: nowrap;
}

The C compiler can glue adjacent string literals into one, like

printf("foo: %s "
       "bar: %d", foo, bar);

The preprocessor can use a backslash as a last character of the line, not counting CR (or CR/LF, if you are from Windowsland):

printf("foo %s \
bar: %d", foo, bar);

Make sure you have the prerequisite, a JVM (http://wiki.eclipse.org/Eclipse/Installation#Install_a_JVM) installed.

This will be a JRE and JDK package.

There are a number of sources which includes: http://www.oracle.com/technetwork/java/javase/downloads/index.html.

Use atoi() from <stdlib.h>

http://linux.die.net/man/3/atoi

Or, write your own atoi() function which will convert char* to int

int a2i(const char *s)
{
  int sign=1;
  if(*s == '-'){
    sign = -1;
    s++;
  }
  int num=0;
  while(*s){
    num=((*s)-'0')+num*10;
    s++;   
  }
  return num*sign;
}

Objective-C:

[label setFont: [label.font fontWithSize: sizeYouWant]];

Swift:

label.font = label.font.fontWithSize(sizeYouWant)

just changes font size of a UILabel.

It is little tricky when you try to combine optional parameter and default value for that parameter. Like this,

func test(param: Int? = nil)

These two are completely opposite ideas. When you have an optional type parameter but you also provide default value to it, it is no more an optional type now since it has a default value. Even if the default is nil, swift simply removes the optional binding without checking what the default value is.

So it is always better not to use nil as default value.

Set the html tag, too. This way no weird position hacks are required.

pygame is not distributed via pip. See this link which provides windows binaries ready for installation.

1. Install python
2. Make sure you have python on your PATH
3. Download the appropriate wheel from this link
4. Install pip using this tutorial

5. Finally, use these commands to install pygame wheel with pip

   • Python 2 (usually called pip)

     • pip install file.whl

   • Python 3 (usually called pip3)

     • pip3 install file.whl

Another tutorial for installing pygame for windows can be found here. Although the instructions are for 64bit windows, it can still be applied to 32bit

A simple solution:

   <a href="#" onmouseover="this.style.color='orange';" onmouseout="this.style.color='';">My Link</a>

Or

<script>
 /** Change the style **/
 function overStyle(object){
    object.style.color = 'orange';
    // Change some other properties ...
 }

 /** Restores the style **/
 function outStyle(object){
    object.style.color = 'orange';
    // Restore the rest ...
 }
</script>

<a href="#" onmouseover="overStyle(this)" onmouseout="outStyle(this)">My Link</a>

Linq to Sql.

Sql server will cache the query plans, so there's no performance gain for sprocs.

Your linq statements, on the other hand, will be logically part of and tested with your application. Sprocs are always a bit separated and are harder to maintain and test.

If I was working on a new application from scratch right now I would just use Linq, no sprocs.

I am not sure if this was possible in TypeScript when the question was originally asked, but my preferred solution is with generics:

class Zoo<T extends Animal> {
    constructor(public readonly AnimalClass: new () => T) {
    }
}

This way variables penguin and lion infer concrete type Penguin or Lion even in the TypeScript intellisense.

const penguinZoo = new Zoo(Penguin);
const penguin = new penguinZoo.AnimalClass(); // `penguin` is of `Penguin` type.

const lionZoo = new Zoo(Lion);
const lion = new lionZoo.AnimalClass(); // `lion` is `Lion` type.

The functions getElementById and getElementsByClassName are very specific, while querySelector and querySelectorAll are more elaborate. My guess is that they will actually have a worse performance.

Also, you need to check for the support of each function in the browsers you are targetting. The newer it is, the higher probability of lack of support or the function being "buggy".

Use notepad ++ . you can find them easily

Or you can View source from FIREfox - Unclosed divs will be shown in RED

Well this might appear weird but after installing pycrypto or pycryptodome , we need to update the directory name crypto to Crypto in lib/site-packages

Use String.Format with alignment values.

For example:

String.Format("|{0,5}|{1,5}|{2,5}|{3,5}|", arg0, arg1, arg2, arg3);

To create one formatted row.

to make UITableView sections header not sticky or sticky:

1. change the table view's style - make it grouped for not sticky & make it plain for sticky section headers - do not forget: you can do it from storyboard without writing code. (click on your table view and change it is style from the right Side/ component menu)

2. if you have extra components such as custom views or etc. please check the table view's margins to create appropriate design. (such as height of header for sections & height of cell at index path, sections)

Replacing :

SparkConf sparkConf = new SparkConf().setAppName("SOME APP NAME");
WITH
SparkConf sparkConf = new SparkConf().setAppName("SOME APP NAME").setMaster("local[2]").set("spark.executor.memory","1g");

Did the magic.

I encountered the same problem. Strange, but the reason was that the object Scanner interprets fractions depending on localization of system. If the current localization uses a comma to separate parts of the fractions, the fraction with the dot will turn into type String. Hence the error ...

In general you can concatenate a whole sequence of arrays along any axis:

numpy.concatenate( LIST, axis=0 )

but you do have to worry about the shape and dimensionality of each array in the list (for a 2-dimensional 3x5 output, you need to ensure that they are all 2-dimensional n-by-5 arrays already). If you want to concatenate 1-dimensional arrays as the rows of a 2-dimensional output, you need to expand their dimensionality.

As Jorge's answer points out, there is also the function stack, introduced in numpy 1.10:

numpy.stack( LIST, axis=0 )

This takes the complementary approach: it creates a new view of each input array and adds an extra dimension (in this case, on the left, so each n-element 1D array becomes a 1-by-n 2D array) before concatenating. It will only work if all the input arrays have the same shape—even along the axis of concatenation.

vstack (or equivalently row_stack) is often an easier-to-use solution because it will take a sequence of 1- and/or 2-dimensional arrays and expand the dimensionality automatically where necessary and only where necessary, before concatenating the whole list together. Where a new dimension is required, it is added on the left. Again, you can concatenate a whole list at once without needing to iterate:

numpy.vstack( LIST )

This flexible behavior is also exhibited by the syntactic shortcut numpy.r_[ array1, ...., arrayN ] (note the square brackets). This is good for concatenating a few explicitly-named arrays but is no good for your situation because this syntax will not accept a sequence of arrays, like your LIST.

There is also an analogous function column_stack and shortcut c_[...], for horizontal (column-wise) stacking, as well as an almost-analogous function hstack—although for some reason the latter is less flexible (it is stricter about input arrays' dimensionality, and tries to concatenate 1-D arrays end-to-end instead of treating them as columns).

Finally, in the specific case of vertical stacking of 1-D arrays, the following also works:

numpy.array( LIST )

...because arrays can be constructed out of a sequence of other arrays, adding a new dimension to the beginning.

8 letters from the alphabet - All caps:

UPDATE `tablename` SET `tablename`.`randomstring`= concat(CHAR(FLOOR(65 + (RAND() * 25))),CHAR(FLOOR(65 + (RAND() * 25))),CHAR(FLOOR(65 + (RAND() * 25))),CHAR(FLOOR(65 + (RAND() * 25)))CHAR(FLOOR(65 + (RAND() * 25))),CHAR(FLOOR(65 + (RAND() * 25))),CHAR(FLOOR(65 + (RAND() * 25))),CHAR(FLOOR(65 + (RAND() * 25))));

I also had the same error. In my case reason was I have created a update trigger on a table and under that trigger I am again updating the same table. And when I have removed the update statement from the trigger my problem has been resolved.

module.exports and exports both point to the same object before the module is evaluated.

Any property you add to the module.exports object will be available when your module is used in another module using require statement. exports is a shortcut made available for the same thing. For instance:

module.exports.add = (a, b) => a+b

is equivalent to writing:

exports.add = (a, b) => a+b

So it is okay as long as you do not assign a new value to exports variable. When you do something like this:

exports = (a, b) => a+b 

as you are assigning a new value to exports it no longer has reference to the exported object and thus will remain local to your module.

If you are planning to assign a new value to module.exports rather than adding new properties to the initial object made available, you should probably consider doing as given below:

module.exports = exports = (a, b) => a+b

Node.js website has a very good explanation of this.

If you use Kotlin, you can use extension functions as such, for example:

fun <T> LongSparseArray<T>.valuesIterator(): Iterator<T> {
    val nSize = this.size()
    return object : Iterator<T> {
        var i = 0
        override fun hasNext(): Boolean = i < nSize
        override fun next(): T = valueAt(i++)
    }
}

fun <T> LongSparseArray<T>.keysIterator(): Iterator<Long> {
    val nSize = this.size()
    return object : Iterator<Long> {
        var i = 0
        override fun hasNext(): Boolean = i < nSize
        override fun next(): Long = keyAt(i++)
    }
}

fun <T> LongSparseArray<T>.entriesIterator(): Iterator<Pair<Long, T>> {
    val nSize = this.size()
    return object : Iterator<Pair<Long, T>> {
        var i = 0
        override fun hasNext(): Boolean = i < nSize
        override fun next() = Pair(keyAt(i), valueAt(i++))
    }
}

You can also convert to a list, if you wish. Example:

sparseArray.keysIterator().asSequence().toList()

I think it might even be safe to delete items using remove on the LongSparseArray itself (not on the iterator), as it is in ascending order.

EDIT: Seems there is even an easier way, by using collection-ktx (example here) . It's implemented in a very similar way to what I wrote, actally.

Gradle requires this:

implementation 'androidx.core:core-ktx:#'
implementation 'androidx.collection:collection-ktx:#'

Here's the usage for LongSparseArray :

    val sparse= LongSparseArray<String>()
    for (key in sparse.keyIterator()) {
    }
    for (value in sparse.valueIterator()) {
    }
    sparse.forEach { key, value -> 
    }

And for those that use Java, you can use LongSparseArrayKt.keyIterator , LongSparseArrayKt.valueIterator and LongSparseArrayKt.forEach , for example. Same for the other cases.

USe this function for date comparison in javascript:

    function fn_DateCompare(DateA, DateB) {
      var a = new Date(DateA);
      var b = new Date(DateB);

      var msDateA = Date.UTC(a.getFullYear(), a.getMonth()+1, a.getDate());
      var msDateB = Date.UTC(b.getFullYear(), b.getMonth()+1, b.getDate());

      if (parseFloat(msDateA) < parseFloat(msDateB))
        return -1;  // less than
      else if (parseFloat(msDateA) == parseFloat(msDateB))
        return 0;  // equal
      else if (parseFloat(msDateA) > parseFloat(msDateB))
        return 1;  // greater than
      else
        return null;  // error
  }

Hope you understand !have fun !

Generally this is due to the DOM being updated and you trying to access an updated/new element -- but the DOM's refreshed so it's an invalid reference you have..

Get around this by first using an explicit wait on the element to ensure the update is complete, then grab a fresh reference to the element again.

Here's some psuedo code to illustrate (Adapted from some C# code I use for EXACTLY this issue):

WebDriverWait wait = new WebDriverWait(browser, TimeSpan.FromSeconds(10));
IWebElement aRow = browser.FindElement(By.XPath(SOME XPATH HERE);
IWebElement editLink = aRow.FindElement(By.LinkText("Edit"));

//this Click causes an AJAX call
editLink.Click();

//must first wait for the call to complete
wait.Until(ExpectedConditions.ElementExists(By.XPath(SOME XPATH HERE));

//you've lost the reference to the row; you must grab it again.
aRow = browser.FindElement(By.XPath(SOME XPATH HERE);

//now proceed with asserts or other actions.

Hope this helps!

Use str.replace.

>>> papa.replace('papa', '')
' is a good man'
>>> app.replace('papa', '')
'app is important'

Alternatively use re and use regular expressions. This will allow the removal of leading/trailing spaces.

>>> import re
>>> papa = 'papa is a good man'
>>> app = 'app is important'
>>> papa3 = 'papa is a papa, and papa'
>>>
>>> patt = re.compile('(\s*)papa(\s*)')
>>> patt.sub('\\1mama\\2', papa)
'mama is a good man'
>>> patt.sub('\\1mama\\2', papa3)
'mama is a mama, and mama'
>>> patt.sub('', papa3)
'is a, and'

.msi files are windows installer files without the windows installer runtime, setup.exe can be any executable programm (probably one that installs stuff on your computer)

If you are asking about actual command line makefiles then you can export a makefile, or you can call MSBuild on a solution file from the command line. What exactly do you want to do with the makefile?

You can do a search on SO for MSBuild for more details.

Yes, as Earwicker said, it's pretty much the equivalent to LINQ's select and has very little to do with Ruby's and Python's yield. Basically, where in C# you would write

from ... select ??? 

in Scala you have instead

for ... yield ???

It's also important to understand that for-comprehensions don't just work with sequences, but with any type which defines certain methods, just like LINQ:

• If your type defines just map, it allows for-expressions consisting of a single generator.
• If it defines flatMap as well as map, it allows for-expressions consisting of several generators.
• If it defines foreach, it allows for-loops without yield (both with single and multiple generators).
• If it defines filter, it allows for-filter expressions starting with an if in the for expression.

believe there should be a way in accessing file system.

Include node.d.ts using npm i @types/node. And then create a new tsconfig.json file (npx tsc --init) and create a .ts file as followed:

import fs from 'fs';
fs.readFileSync('foo.txt','utf8');

You can use other functions in fs as well : https://nodejs.org/api/fs.html

Good question. These two operators work the same in PHP and C#.

| is a bitwise OR. It will compare two values by their bits. E.g. 1101 | 0010 = 1111. This is extremely useful when using bit options. E.g. Read = 01 (0X01) Write = 10 (0X02) Read-Write = 11 (0X03). One useful example would be opening files. A simple example would be:

File.Open(FileAccess.Read | FileAccess.Write);  //Gives read/write access to the file

|| is a logical OR. This is the way most people think of OR and compares two values based on their truth. E.g. I am going to the store or I will go to the mall. This is the one used most often in code. For example:

if(Name == "Admin" || Name == "Developer") { //allow access } //checks if name equals Admin OR Name equals Developer

Setting command timeout to 2 minutes.

 scGetruntotals.CommandTimeout = 120;

but you can optimize your stored Procedures to decrease that time! like

• removing courser or while and etc
• using paging
• using #tempTable and @variableTable

Excellent!

I share with you, code from a function that compares passwords:

SET pSignal =
(SELECT DECODE(r.usignal,'YOURSTRINGKEY') FROM rsw_uds r WHERE r.uname =
in_usdname AND r.uvige = 1);

SET pSuccess =(SELECT in_usdsignal LIKE BINARY pSignal);

IF pSuccess = 1 THEN
      /*Your code if match*/
ELSE
      /*Your code if don't match*/

END IF;

Another solution is to use stat_count() when dealing with discrete variables (and stat_bin() with continuous ones).

ggplot(data = df, aes(x = x)) +
geom_bar(stat = "count") + 
stat_count(geom = "text", colour = "white", size = 3.5,
aes(label = ..count..),position=position_stack(vjust=0.5))

After changing the context root in project properties you have to remove your web application from Tomcat (using Add and Remove... on the context menu of the server), redeploy, then re-add your application and redeploy. It worked for me.

If you are struck you have another choice: select the Tomcat server in the Servers view. Double clicking on that server (or selecting Open in the context menu) brings a multipage editor where there is a Modules page. Here you can change the root context of your module (called Path on this page).

This is a supplemental answer for those arriving here based on the question title (like I did) and don't need to deal with the security issues related to saving passwords.

How to use Shared Preferences

User settings are generally saved locally in Android using SharedPreferences with a key-value pair. You use the String key to save or look up the associated value.

Write to Shared Preferences

String key = "myInt";
int valueToSave = 10;

SharedPreferences sharedPref = PreferenceManager.getDefaultSharedPreferences(context);
SharedPreferences.Editor editor = sharedPref.edit();
editor.putInt(key, valueToSave).commit();

Use apply() instead of commit() to save in the background rather than immediately.

Read from Shared Preferences

String key = "myInt";
int defaultValue = 0;

SharedPreferences sharedPref = PreferenceManager.getDefaultSharedPreferences(context);
int savedValue = sharedPref.getInt(key, defaultValue);

The default value is used if the key isn't found.

Notes

• Rather than using a local key String in multiple places like I did above, it would be better to use a constant in a single location. You could use something like this at the top of your settings activity:

    final static String PREF_MY_INT_KEY = "myInt";
  

• I used an int in my example, but you can also use putString(), putBoolean(), getString(), getBoolean(), etc.

• See the documentation for more details.

• There are multiple ways to get SharedPreferences. See this answer for what to look out for.

Try

xargs -n2  printf "%-20s%s\n"

or even

xargs printf "%-20s%s\n"

if input is not very large.

GNU parallel and xargs

These two tools that can make scripts simpler, and also control the maximum number of threads (thread pool). E.g.:

seq 10 | xargs -P4 -I'{}' echo '{}'

or:

seq 10 | parallel -j4  echo '{}'

In android studio: reduce minSDKversion. It will work...

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "healthcare.acceliant.trianz.com.myapplication"
        minSdkVersion 11
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:23.1.1'
}

Below code worked fine for me

using System.Diagnostics;

public void ExecuteBatFile()
{
    Process proc = null;

    string _batDir = string.Format(@"C:\");
    proc = new Process();
    proc.StartInfo.WorkingDirectory = _batDir;
    proc.StartInfo.FileName = "myfile.bat";
    proc.StartInfo.CreateNoWindow = false;
    proc.Start();
    proc.WaitForExit();
    ExitCode = proc.ExitCode;
    proc.Close();
    MessageBox.Show("Bat file executed...");
}

In my case, none of the solutions were working because I did not manually go into my ~/.gitconfig and remove the following as I created a new key that was no longer my older X.509 key so I removed the following and then my new key began to work.

[gpg]
    program = gpg
    format = x509
[gpg "x509"]
    program = smimesign

new Date(moment('23:04:33', "HH:mm")).getTime()

Output: 1499755980000 (in millisecond) ( 1499755980000/1000) (in second)

Note : this output calculate diff from 1970-01-01 12:0:0 to now and we need to implement the moment.js

Use value instanceof YourClass

There are different ways to check Oracle Database Version. Easiest way is to run the below SQL query to check Oracle Version.

SQL> SELECT * FROM PRODUCT_COMPONENT_VERSION;

SQL> SELECT * FROM v$version;

I struggled with this for a long time. I am using Angular 6 and I found that

let headers = new HttpHeaders();
headers = headers.append('key', 'value');

did not work. But what did work was

let headers = new HttpHeaders().append('key', 'value');

did, which makes sense when you realize they are immutable. So having created a header you can't add to it. I haven't tried it, but I suspect

let headers = new HttpHeaders();
let headers1 = headers.append('key', 'value');

would work too.

If you are interested in the indexes, the best choice is np.argsort(a)

a = np.random.randint(0, 100, 10)
sorted_idx = np.argsort(a)

Use logging:

import unittest
import logging
import inspect
import os

logging_level = logging.INFO

try:
    log_file = os.environ["LOG_FILE"]
except KeyError:
    log_file = None

def logger(stack=None):
    if not hasattr(logger, "initialized"):
        logging.basicConfig(filename=log_file, level=logging_level)
        logger.initialized = True
    if not stack:
        stack = inspect.stack()
    name = stack[1][3]
    try:
        name = stack[1][0].f_locals["self"].__class__.__name__ + "." + name
    except KeyError:
        pass
    return logging.getLogger(name)

def todo(msg):
    logger(inspect.stack()).warning("TODO: {}".format(msg))

def get_pi():
    logger().info("sorry, I know only three digits")
    return 3.14

class Test(unittest.TestCase):

    def testName(self):
        todo("use a better get_pi")
        pi = get_pi()
        logger().info("pi = {}".format(pi))
        todo("check more digits in pi")
        self.assertAlmostEqual(pi, 3.14)
        logger().debug("end of this test")
        pass

Usage:

# LOG_FILE=/tmp/log python3 -m unittest LoggerDemo
.
----------------------------------------------------------------------
Ran 1 test in 0.047s

OK
# cat /tmp/log
WARNING:Test.testName:TODO: use a better get_pi
INFO:get_pi:sorry, I know only three digits
INFO:Test.testName:pi = 3.14
WARNING:Test.testName:TODO: check more digits in pi

If you do not set LOG_FILE, logging will got to stderr.

Open the php.ini file in your server environment and remove ; from ;extension=sockets. if it's doesn't work, you have to download the socket extension for PHP and put it into ext directory in the php installation path. Restart your http server and everything should work.

You haven't stated where you're looking for the element. If it's within the scope of a controller, it is possible, despite the chorus you'll hear about it not being the 'Angular Way'. The chorus is right, but sometimes, in the real world, it's unavoidable. (If you disagree, get in touch—I have a challenge for you.)

If you pass $element into a controller, like you would $scope, you can use its find() function. Note that, in the jQueryLite included in Angular, find() will only locate tags by name, not attribute. However, if you include the full-blown jQuery in your project, all the functionality of find() can be used, including finding by attribute.

So, for this HTML:

<div ng-controller='MyCtrl'>
    <div>
        <div name='foo' class='myElementClass'>this one</div>
    </div>
</div>

This AngularJS code should work:

angular.module('MyClient').controller('MyCtrl', [
    '$scope',
    '$element',
    '$log',
    function ($scope, $element, $log) {

        // Find the element by its class attribute, within your controller's scope
        var myElements = $element.find('.myElementClass');

        // myElements is now an array of jQuery DOM elements

        if (myElements.length == 0) {
            // Not found. Are you sure you've included the full jQuery?
        } else {
            // There should only be one, and it will be element 0
            $log.debug(myElements[0].name); // "foo"
        }

    }
]);

I tried replacing value with Value and it worked out. It has set the value in input tag now.

Here are three ways to do it:

Long l = 123L;
Integer correctButComplicated = Integer.valueOf(l.intValue());
Integer withBoxing = l.intValue();
Integer terrible = (int) (long) l;

All three versions generate almost identical byte code:

 0  ldc2_w <Long 123> [17]
 3  invokestatic java.lang.Long.valueOf(long) : java.lang.Long [19]
 6  astore_1 [l]
 // first
 7  aload_1 [l]
 8  invokevirtual java.lang.Long.intValue() : int [25]
11  invokestatic java.lang.Integer.valueOf(int) : java.lang.Integer [29]
14  astore_2 [correctButComplicated]
// second
15  aload_1 [l]
16  invokevirtual java.lang.Long.intValue() : int [25]
19  invokestatic java.lang.Integer.valueOf(int) : java.lang.Integer [29]
22  astore_3 [withBoxing]
// third
23  aload_1 [l]
// here's the difference:
24  invokevirtual java.lang.Long.longValue() : long [34]
27  l2i
28  invokestatic java.lang.Integer.valueOf(int) : java.lang.Integer [29]
31  astore 4 [terrible]

The 10013 errors should disappear."

The biggest problem is probably that one can't ensure immutability on A and B (see How to ensure that type parameters are immutable) so hashCode() may give inconsistent results for the same Pair after is inserted in a collection for instance (this would give undefined behavior, see Defining equals in terms of mutable fields). For a particular (non generic) Pair class the programmer may ensure immutability by carefully choosing A and B to be immutable.

Anyway, clearing generic's warnings from @PeterLawrey's answer (java 1.7) :

public class Pair<A extends Comparable<? super A>,
                    B extends Comparable<? super B>>
        implements Comparable<Pair<A, B>> {

    public final A first;
    public final B second;

    private Pair(A first, B second) {
        this.first = first;
        this.second = second;
    }

    public static <A extends Comparable<? super A>,
                    B extends Comparable<? super B>>
            Pair<A, B> of(A first, B second) {
        return new Pair<A, B>(first, second);
    }

    @Override
    public int compareTo(Pair<A, B> o) {
        int cmp = o == null ? 1 : (this.first).compareTo(o.first);
        return cmp == 0 ? (this.second).compareTo(o.second) : cmp;
    }

    @Override
    public int hashCode() {
        return 31 * hashcode(first) + hashcode(second);
    }

    // TODO : move this to a helper class.
    private static int hashcode(Object o) {
        return o == null ? 0 : o.hashCode();
    }

    @Override
    public boolean equals(Object obj) {
        if (!(obj instanceof Pair))
            return false;
        if (this == obj)
            return true;
        return equal(first, ((Pair<?, ?>) obj).first)
                && equal(second, ((Pair<?, ?>) obj).second);
    }

    // TODO : move this to a helper class.
    private boolean equal(Object o1, Object o2) {
        return o1 == o2 || (o1 != null && o1.equals(o2));
    }

    @Override
    public String toString() {
        return "(" + first + ", " + second + ')';
    }
}

Additions/corrections much welcome :) In particular I am not quite sure about my use of Pair<?, ?>.

Note: z-index only works on positioned elements (position:absolute, position:relative, or position:fixed). Use one of those.

Note that ≪Copy all as HAR≫ does not contain response body.

You can get response body via ≪Save as HAR with Content≫, but it breaks if you have any more than a trivial amount of logs (I tried once with only 8k requests and it doesn't work.) To solve this, you can script an output yourself using _request.contentData().

When there's too many logs, even _request.contentData() and ≪Copy response≫ would fail, hopefully they would fix this problem. Until then, inspecting any more than a trivial amount of network logs cannot be properly done with Chrome Network Inspector and its best to use another tool.

I was having an issue recursively loading resources in my Spring app, and found that the issue was I should be using resource.getInputStream. Here's an example showing how to recursively read in all files in config/myfiles that are json files.

Example.java

private String myFilesResourceUrl = "config/myfiles/**/";
private String myFilesResourceExtension = "json";

ResourceLoader rl = new ResourceLoader();

// Recursively get resources that match. 
// Big note: If you decide to iterate over these, 
// use resource.GetResourceAsStream to load the contents
// or use the `readFileResource` of the ResourceLoader class.
Resource[] resources = rl.getResourcesInResourceFolder(myFilesResourceUrl, myFilesResourceExtension);

// Recursively get resource and their contents that match. 
// This loads all the files into memory, so maybe use the same approach 
// as this method, if need be.
Map<Resource,String> contents = rl.getResourceContentsInResourceFolder(myFilesResourceUrl, myFilesResourceExtension);

ResourceLoader.java

import java.io.IOException;
import java.io.InputStream;
import java.nio.charset.Charset;
import java.util.HashMap;
import java.util.Map;
import org.springframework.core.io.Resource;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.core.io.support.ResourcePatternResolver;
import org.springframework.util.StreamUtils;

public class ResourceLoader {
  public Resource[] getResourcesInResourceFolder(String folder, String extension) {
    ResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
    try {
      String resourceUrl = folder + "/*." + extension;
      Resource[] resources = resolver.getResources(resourceUrl);
      return resources;
    } catch (IOException e) {
      throw new RuntimeException(e);
    }
  }

  public String readResource(Resource resource) throws IOException {
    try (InputStream stream = resource.getInputStream()) {
      return StreamUtils.copyToString(stream, Charset.defaultCharset());
    }
  }

  public Map<Resource, String> getResourceContentsInResourceFolder(
      String folder, String extension) {
    Resource[] resources = getResourcesInResourceFolder(folder, extension);

    HashMap<Resource, String> result = new HashMap<>();
    for (var resource : resources) {
      try {
        String contents = readResource(resource);
        result.put(resource, contents);
      } catch (IOException e) {
        throw new RuntimeException("Could not load resource=" + resource + ", e=" + e);
      }
    }
    return result;
  }
}

Use DATALENGTH method, for example:

SELECT length = DATALENGTH(myField)
FROM myTABLE

http://fiji.sc/Uber-JAR provides an excellent explanation of the alternatives:

There are three common methods for constructing an uber-JAR:

1. Unshaded. Unpack all JAR files, then repack them into a single JAR.
   • Pro: Works with Java's default class loader.
   • Con: Files present in multiple JAR files with the same path (e.g., META-INF/services/javax.script.ScriptEngineFactory) will overwrite one another, resulting in faulty behavior.
   • Tools: Maven Assembly Plugin, Classworlds Uberjar
2. Shaded. Same as unshaded, but rename (i.e., "shade") all packages of all dependencies.
   • Pro: Works with Java's default class loader. Avoids some (not all) dependency version clashes.
   • Con: Files present in multiple JAR files with the same path (e.g., META-INF/services/javax.script.ScriptEngineFactory) will overwrite one another, resulting in faulty behavior.
   • Tools: Maven Shade Plugin
3. JAR of JARs. The final JAR file contains the other JAR files embedded within.
   • Pro: Avoids dependency version clashes. All resource files are preserved.
   • Con: Needs to bundle a special "bootstrap" classloader to enable Java to load classes from the wrapped JAR files. Debugging class loader issues becomes more complex.
   • Tools: Eclipse JAR File Exporter, One-JAR.

Here is a variation of ben blank's answer, if you don't like tuples.

This saves you a few characters.

var keys = [];
for (var key in sortme) {
  keys.push(key);
}

keys.sort(function(k0, k1) {
  var a = sortme[k0];
  var b = sortme[k1];
  return a < b ? -1 : (a > b ? 1 : 0);
});

for (var i = 0; i < keys.length; ++i) {
  var key = keys[i];
  var value = sortme[key];
  // Do something with key and value.
}

You'll see people using the Timer class to do this. Unfortunately, it isn't always accurate. Your best bet is to get the system time when the user enters input, calculate a target system time, and check if the system time has exceeded the target system time. If it has, then break out of the loop.

I don't know if it's a stupid answer, but resolved this problem by storing a flag in shared preferences every time I entered onCreate() of any activity, then I used the value from shered preferences to find out what it's the foreground activity.

This borrows from a few other answers here but I thought it might help someone. If you define the following function on your custom object, then you have a factory function that you can pass a generic object into and it will return for you an instance of the class.

CustomObject.create = function (obj) {
    var field = new CustomObject();
    for (var prop in obj) {
        if (field.hasOwnProperty(prop)) {
            field[prop] = obj[prop];
        }
    }

    return field;
}

Use like this

var typedObj = CustomObject.create(genericObj);

 byte[] byteArray = new byte[102400];
 base64String = Base64.encode(byteArray);

That code will encode 102400 bytes, no matter how much data you actually use in the array.

while ((bytesRead = fis.read(byteArray)) != -1)

You need to use the value of bytesRead somewhere.

Also, this may not read the whole file into the array in one go (it only reads as much as is in the I/O buffer), so your loop will probably not work, you may end up with half an image in your array.

I'd use Apache Commons IOUtils here:

 Base64.encode(FileUtils.readFileToByteArray(file));

tl;dr non-capturing groups, as the name suggests are the parts of the regex that you do not want to be included in the match and ?: is a way to define a group as being non-capturing.

Let's say you have an email address [email protected]. The following regex will create two groups, the id part and @example.com part. (\p{Alpha}*[a-z])(@example.com). For simplicity's sake, we are extracting the whole domain name including the @ character.

Now let's say, you only need the id part of the address. What you want to do is to grab the first group of the match result, surrounded by () in the regex and the way to do this is to use the non-capturing group syntax, i.e. ?:. So the regex (\p{Alpha}*[a-z])(?:@example.com) will return just the id part of the email.

use jquery Every time Plugin .using this you can do ajax call for "X" time period

$("#select").everyTime(1000,function(i) {
//ajax call
}

you can also use setInterval

Use cbind e.g.

df <- data.frame(b = runif(6), c = rnorm(6))
cbind(a = 0, df)

giving:

> cbind(a = 0, df)
  a         b          c

to suppress inspection just for single statement but not the whole method.

Ha. Sorry, I mis-read your post. I've used cucumber to test it before. It worked out nicely.

I modified Alan's answer above to restrict the number to the specified min/max. If you enter a number outside the range, it will set the min or max value after 1500ms. If you clear the field completely, it will not set anything.

HTML:

<input type="text" ng-model="employee.age" min="18" max="99" valid-number />

Javascript:

var app = angular.module('myApp', []);

app.controller('MainCtrl', function($scope) {});

app.directive('validNumber', function($timeout) {
    return {
        require: '?ngModel',
        link: function(scope, element, attrs, ngModelCtrl) {
            if (!ngModelCtrl) {
                return;
            }

            var min = +attrs.min;
            var max = +attrs.max;
            var lastValue = null;
            var lastTimeout = null;
            var delay = 1500;

            ngModelCtrl.$parsers.push(function(val) {
                if (angular.isUndefined(val)) {
                    val = '';
                }            

                if (lastTimeout) {
                    $timeout.cancel(lastTimeout);
                }

                if (!lastValue) {
                    lastValue = ngModelCtrl.$modelValue;
                }

                if (val.length) {
                    var value = +val;
                    var cleaned = val.replace( /[^0-9]+/g, ''); 

                    // This has no non-numeric characters
                    if (val.length === cleaned.length) {
                        var clean = +cleaned;

                        if (clean < min) {
                            clean = min;
                        } else if (clean > max) {
                            clean = max;
                        }

                        if (value !== clean || value !== lastValue) {
                            lastTimeout = $timeout(function () {
                                lastValue = clean;
                                ngModelCtrl.$setViewValue(clean);
                                ngModelCtrl.$render();
                            }, delay);
                        }
                    // This has non-numeric characters, filter them out
                    } else {
                        ngModelCtrl.$setViewValue(lastValue);
                        ngModelCtrl.$render();
                    }
                }

                return lastValue;
            });

            element.bind('keypress', function(event) {
                if (event.keyCode === 32) {
                    event.preventDefault();
                }
            });

            element.on('$destroy', function () {
                element.unbind('keypress');
            });
        }
    };
});

I found this while passing and looking for answers on how to compile a set of csvs into a single excel doc with the worksheets (tabs) named after the csv files. It is a nice function. Sadly, I cannot run them on my network :( so i do not know how well it works.

It prevents disclosure of the response through JSON hijacking.

In theory, the content of HTTP responses are protected by the Same Origin Policy: pages from one domain cannot get any pieces of information from pages on the other domain (unless explicitly allowed).

An attacker can request pages on other domains on your behalf, e.g. by using a <script src=...> or <img> tag, but it can't get any information about the result (headers, contents).

Thus, if you visit an attacker's page, it couldn't read your email from gmail.com.

Except that when using a script tag to request JSON content, the JSON is executed as JavaScript in an attacker's controlled environment. If the attacker can replace the Array or Object constructor or some other method used during object construction, anything in the JSON would pass through the attacker's code, and be disclosed.

Note that this happens at the time the JSON is executed as JavaScript, not at the time it's parsed.

There are multiple countermeasures:

Making sure the JSON never executes

By placing a while(1); statement before the JSON data, Google makes sure that the JSON data is never executed as JavaScript.

Only a legitimate page could actually get the whole content, strip the while(1);, and parse the remainder as JSON.

Things like for(;;); have been seen at Facebook for instance, with the same results.

Making sure the JSON is not valid JavaScript

Similarly, adding invalid tokens before the JSON, like &&&START&&&, makes sure that it is never executed.

Always return JSON with an Object on the outside

This is OWASP recommended way to protect from JSON hijacking and is the less intrusive one.

Similarly to the previous counter-measures, it makes sure that the JSON is never executed as JavaScript.

A valid JSON object, when not enclosed by anything, is not valid in JavaScript:

eval('{"foo":"bar"}')
// SyntaxError: Unexpected token :

This is however valid JSON:

JSON.parse('{"foo":"bar"}')
// Object {foo: "bar"}

So, making sure you always return an Object at the top level of the response makes sure that the JSON is not valid JavaScript, while still being valid JSON.

As noted by @hvd in the comments, the empty object {} is valid JavaScript, and knowing the object is empty may itself be valuable information.

Comparison of above methods

The OWASP way is less intrusive, as it needs no client library changes, and transfers valid JSON. It is unsure whether past or future browser bugs could defeat this, however. As noted by @oriadam, it is unclear whether data could be leaked in a parse error through an error handling or not (e.g. window.onerror).

Google's way requires a client library in order for it to support automatic de-serialization and can be considered to be safer with regard to browser bugs.

Both methods require server side changes in order to avoid developers accidentally sending vulnerable JSON.

You can use a simple if statement instead of continue. So instead of the way you have your code, you can try:

try(Stream<String> lines = Files.lines(path, StandardCharsets.ISO_8859_1)){
            filteredLines = lines.filter(...).foreach(line -> {
           ...
           if(!...) {
              // Code you want to run
           }
           // Once the code runs, it will continue anyway
    });
}

The predicate in the if statement will just be the opposite of the predicate in your if(pred) continue; statement, so just use ! (logical not).

You have to define a PersistentVolume providing disc space to be consumed by the PersistentVolumeClaim.

When using storageClass Kubernetes is going to enable "Dynamic Volume Provisioning" which is not working with the local file system.

To solve your issue:

• Provide a PersistentVolume fulfilling the constraints of the claim (a size >= 100Mi)
• Remove the storageClass-line from the PersistentVolumeClaim
• Remove the StorageClass from your cluster

How do these pieces play together?

At creation of the deployment state-description it is usually known which kind (amount, speed, ...) of storage that application will need.
To make a deployment versatile you'd like to avoid a hard dependency on storage. Kubernetes' volume-abstraction allows you to provide and consume storage in a standardized way.

The PersistentVolumeClaim is used to provide a storage-constraint alongside the deployment of an application.

The PersistentVolume offers cluster-wide volume-instances ready to be consumed ("bound"). One PersistentVolume will be bound to one claim. But since multiple instances of that claim may be run on multiple nodes, that volume may be accessed by multiple nodes.

A PersistentVolume without StorageClass is considered to be static.

"Dynamic Volume Provisioning" alongside with a StorageClass allows the cluster to provision PersistentVolumes on demand. In order to make that work, the given storage provider must support provisioning - this allows the cluster to request the provisioning of a "new" PersistentVolume when an unsatisfied PersistentVolumeClaim pops up.

Example PersistentVolume

In order to find how to specify things you're best advised to take a look at the API for your Kubernetes version, so the following example is build from the API-Reference of K8S 1.17:

apiVersion: v1
kind: PersistentVolume
metadata:
  name: ckan-pv-home
  labels:
    type: local
spec:
  capacity:
    storage: 100Mi
  hostPath:
    path: "/mnt/data/ckan"

The PersistentVolumeSpec allows us to define multiple attributes. I chose a hostPath volume which maps a local directory as content for the volume. The capacity allows the resource scheduler to recognize this volume as applicable in terms of resource needs.

If you have problems with numbers (say 1, 2, 10, 12 which will be sorted 1, 10, 12, 2) you can use LINQ:

var arr = arr.OrderBy(x=>x).ToArray();

CSS "classes" are not OOP "classes". The inheritance works the other way around.
A DOM element can have many classes, either directly or inherited or otherwise associated, which will all be applied in order, overriding earlier defined properties:

<div class="foo bar">

.foo {
    color: blue;
    width: 200px;
}

.bar {
    color: red;
}

The div will be 200px wide and have the color red.

You override properties of DOM elements with different classes, not properties of CSS classes. CSS "classes" are rulesets, the same way ids or tags can be used as rulesets.

Note that the order in which the classes are applied depends on the precedence and specificity of the selector, which is a complex enough topic in itself.

So you need to use what we call promise. Read how angular handles it here, https://docs.angularjs.org/api/ng/service/$q. Turns our $http support promises inherently so in your case we'll do something like this,

(function() {
  "use strict";
  var serviceCallJson = function($http) {

      this.getCustomers = function() {
        // http method anyways returns promise so you can catch it in calling function
        return $http({
            method : 'get',
            url : '../viewersData/userPwdPair.json'
          });
      }

  }

  var validateIn = function (serviceCallJson, $q) {

      this.called = function(username, password) {
          var deferred = $q.defer(); 
          serviceCallJson.getCustomers().then( 
            function( returnedData ) {
              console.log(returnedData); // you should get output here this is a success handler
              var i = 0;
              angular.forEach(returnedData, function(value, key){
                while (i < 10) {
                  if(value[i].username == username) {
                    if(value[i].password == password) {
                     alert("Logged In");
                    }
                  }
                  i = i + 1;
                }
              });
            }, 
            function() {

              // this is error handler
            } 
          );
          return deferred.promise;  
      }

  }

  angular.module('assignment1App')
    .service ('serviceCallJson', serviceCallJson)

  angular.module('assignment1App')
  .service ('validateIn', ['serviceCallJson', validateIn])

}())

You should run:

composer dump-autoload

and if does not work you should:

re-install composer

defaultValue instead of value worked for me .

That's probably the C++ runtime library. Since it's a DLL it is not included in your program executable. Your friend can download those libraries from Microsoft.

Convert the image to a byte[] and store that in the database.

Add this column to your model:

public byte[] Content { get; set; }

Then convert your image to a byte array and store that like you would any other data:

public byte[] ImageToByteArray(System.Drawing.Image imageIn)
{
    using(var ms = new MemoryStream())
    {
        imageIn.Save(ms, System.Drawing.Imaging.ImageFormat.Gif);

        return ms.ToArray();
    }
}

public Image ByteArrayToImage(byte[] byteArrayIn)
{
     using(var ms = new MemoryStream(byteArrayIn))
     {
         var returnImage = Image.FromStream(ms);

         return returnImage;
     }
}

Source: Fastest way to convert Image to Byte array

var image = new ImageEntity()
{
   Content = ImageToByteArray(image)
};

_context.Images.Add(image);
_context.SaveChanges();

When you want to get the image back, get the byte array from the database and use the ByteArrayToImage and do what you wish with the Image

This stops working when the byte[] gets to big. It will work for files under 100Mb

I have encountered problems using some example where the cell size of ListView is great. So I have found a solution to my problem which detects the slightest movement of your finger . I've simplified to the minimum possible and is as follows:

private int oldScrolly;


@Override
public void onScrollStateChanged(AbsListView view, int scrollState) {

}

@Override
public void onScroll(AbsListView view, int firstVisibleItem, int    visibleItemCount, int totalItemCount) {

            View view = absListView.getChildAt(0);
            int scrolly = (view == null) ? 0 : -view.getTop() + absListView.getFirstVisiblePosition() * view.getHeight();
            int margin = 10;

            Log.e(TAG, "Scroll y: " + scrolly + " - Item: " + firstVisibleItem);


            if (scrolly > oldScrolly + margin) {
                Log.d(TAG, "SCROLL_UP");
                oldScrolly = scrolly;
            } else if (scrolly < oldScrolly - margin) {
                Log.d(TAG, "SCROLL_DOWN");
                oldScrolly = scrolly;
            }
        }
    });

PD: I use the MARGIN to not detect the scroll until you meet that margin . This avoids problems when I show or hide views and avoid blinking of them.

I like ExportHTML, which exports to html, opens it up in your browser, and optionally opens the system print dialog. Looks good, too. Not a perfect replacement for native printing, but pretty close.

Maybe it's a coincidence that the column order you want happens to have column names in descending alphabetical order. Since that's the case you could just do:

df<-df[,order(colnames(df),decreasing=TRUE)]

That's what I use when I have large files with many columns.

To get all the columns in your result you need to place something as:

SELECT distinct a, Table.* FROM Table

it will place a as the first column and the rest will be ALL of the columns in the same order as your definition. This is, column a will be repeated.

This query should work very well on MySQL:

SELECT concat(left(curdate(),7),'-01') 

A variation on Jorenko's work above allows the elevated process to use the same console (but see my comment below):

def spawn_as_administrator():
    """ Spawn ourself with administrator rights and wait for new process to exit
        Make the new process use the same console as the old one.
          Raise Exception() if we could not get a handle for the new re-run the process
          Raise pywintypes.error() if we could not re-spawn
        Return the exit code of the new process,
          or return None if already running the second admin process. """
    #pylint: disable=no-name-in-module,import-error
    import win32event, win32api, win32process
    import win32com.shell.shell as shell
    if '--admin' in sys.argv:
        return None
    script = os.path.abspath(sys.argv[0])
    params = ' '.join([script] + sys.argv[1:] + ['--admin'])
    SEE_MASK_NO_CONSOLE = 0x00008000
    SEE_MASK_NOCLOSE_PROCESS = 0x00000040
    process = shell.ShellExecuteEx(lpVerb='runas', lpFile=sys.executable, lpParameters=params, fMask=SEE_MASK_NO_CONSOLE|SEE_MASK_NOCLOSE_PROCESS)
    hProcess = process['hProcess']
    if not hProcess:
        raise Exception("Could not identify administrator process to install drivers")
    # It is necessary to wait for the elevated process or else
    #  stdin lines are shared between 2 processes: they get one line each
    INFINITE = -1
    win32event.WaitForSingleObject(hProcess, INFINITE)
    exitcode = win32process.GetExitCodeProcess(hProcess)
    win32api.CloseHandle(hProcess)
    return exitcode

The Replace string function will do that.

Something like this should work unless I'm missing the point:

json.load(urllib2.urlopen("url"))

You will need a PDF renderer. There are a few more or less good ones on the market (ICEPdf, pdfrenderer), but without, you will have to rely on external tools. The free PDF renderers also cannot render embedded fonts, and so will only be good for creating thumbnails (what you eventually want).

My favorite external tool is Ghostscript, which can convert PDFs to images with a single command line invocation.

This converts Postscript (and PDF?) files to bmp for us, just as a guide to modify for your needs (Know you need the env vars for gs to work!):

pushd 
setlocal

Set BIN_DIR=C:\Program Files\IKOffice_ACME\bin
Set GS=C:\Program Files\IKOffice_ACME\gs
Set GS_DLL=%GS%\gs8.54\bin\gsdll32.dll
Set GS_LIB=%GS%\gs8.54\lib;%GS%\gs8.54\Resource;%GS%\fonts
Set Path=%Path%;%GS%\gs8.54\bin
Set Path=%Path%;%GS%\gs8.54\lib

call "%GS%\gs8.54\bin\gswin32c.exe" -q -dSAFER -dNOPAUSE -dBATCH -sDEVICE#bmpmono -r600x600 -sOutputFile#%2 -f %1

endlocal
popd

UPDATE: pdfbox is now able to embed fonts, so no need for Ghostscript anymore.

Using a Service Account might work for you.

If you're only checking if it's a number, is_numeric() is much much better here. It's more readable and a bit quicker than regex.

The issue with your regex here is that it won't allow decimal values, so essentially you've just written is_int() in regex. Regular expressions should only be used when there is a non-standard data format in your input; PHP has plenty of built in validation functions, even an email validator without regex.

JSON_UNESCAPED_UNICODE was added in PHP 5.4 so it looks like you need upgrade your version of PHP to take advantage of it. 5.4 is not released yet though! :(

There is a 5.4 alpha release candidate on QA though if you want to play on your development machine.

Each row in /proc/$PID/maps describes a region of contiguous virtual memory in a process or thread. Each row has the following fields:

address           perms offset  dev   inode   pathname
08048000-08056000 r-xp 00000000 03:0c 64593   /usr/sbin/gpm

• address - This is the starting and ending address of the region in the process's address space
• permissions - This describes how pages in the region can be accessed. There are four different permissions: read, write, execute, and shared. If read/write/execute are disabled, a - will appear instead of the r/w/x. If a region is not shared, it is private, so a p will appear instead of an s. If the process attempts to access memory in a way that is not permitted, a segmentation fault is generated. Permissions can be changed using the mprotect system call.
• offset - If the region was mapped from a file (using mmap), this is the offset in the file where the mapping begins. If the memory was not mapped from a file, it's just 0.
• device - If the region was mapped from a file, this is the major and minor device number (in hex) where the file lives.
• inode - If the region was mapped from a file, this is the file number.
• pathname - If the region was mapped from a file, this is the name of the file. This field is blank for anonymous mapped regions. There are also special regions with names like [heap], [stack], or [vdso]. [vdso] stands for virtual dynamic shared object. It's used by system calls to switch to kernel mode. Here's a good article about it: "What is linux-gate.so.1?"

You might notice a lot of anonymous regions. These are usually created by mmap but are not attached to any file. They are used for a lot of miscellaneous things like shared memory or buffers not allocated on the heap. For instance, I think the pthread library uses anonymous mapped regions as stacks for new threads.

AWK works as a text interpreter that goes linewise for the whole document and that goes fieldwise for each line. Thus $1, $2...$n are references to the fields of each line ($1 is the first field, $2 is the second field, and so on...).

You can define a field separator by using the "-F" switch under the command line or within two brackets with "FS=...".

Now consider the answer of Jürgen:

echo "1: " | awk -F  ":" '/1/ {print $1}'

Above the field, boundaries are set by ":" so we have two fields $1 which is "1" and $2 which is the empty space. After comes the regular expression "/1/" that instructs the filter to output the first field only when the interpreter stumbles upon a line containing such an expression (I mean 1).

The output of the "echo" command is one line that contains "1", so the filter will work...

When dealing with the following example:

echo "1: " | awk '/1/ -F ":" {print $1}'

The syntax is messy and the interpreter chose to ignore the part F ":" and switches to the default field splitter which is the empty space, thus outputting "1:" as the first field and there will be not a second field!

The answer of Jürgen contains the good syntax...

Assuming regular PCRE-style regex flavors:

If you want to check for it as a single, full word, it's \bTest\b, with appropriate flags for case insensitivity if desired and delimiters for your programming language. \b represents a "word boundary", that is, a point between characters where a word can be considered to start or end. For example, since spaces are used to separate words, there will be a word boundary on either side of a space.

If you want to check for it as part of the word, it's just Test, again with appropriate flags for case insensitivity. Note that usually, dedicated "substring" methods tend to be faster in this case, because it removes the overhead of parsing the regex.

>>> import random
>>> x = [1,2,3,4,5]
>>> random.shuffle(x)
>>> x
[5, 2, 4, 3, 1]

If anyone is interested in fetching the absolute reverse url with parameters in a template , the cleanest way is to create your own absolute version of the {% url %} template tag by extending and using existing default code.

Here is my code:

from django import template
from django.template.defaulttags import URLNode, url

register = template.Library()

class AbsURLNode(URLNode):
    def __init__(self, view_name, args, kwargs, asvar):
        super().__init__(view_name, args, kwargs, asvar)

    def render(self, context):
        url     = super().render(context)
        request = context['request']

        return request.build_absolute_uri(url)


@register.tag
def abs_url(parser, token):

    urlNode = url(parser, token)
    return AbsURLNode( urlNode.view_name, urlNode.args, urlNode.kwargs, urlNode.asvar  )

Usage in templates:

{% load wherever_your_stored_this_tag_file %}
{% abs_url 'view_name' parameter %}

will render(example):

http://example.com/view_name/parameter/

instead of

/view_name/parameter/

You can still use <hr> as a horizontal line, and you probably should. In HTML5 it defines a thematic break in content, without making any promises about how it is displayed. The attributes that aren't supported in the HTML5 spec are all related to the tag's appearance. The appearance should be set in CSS, not in the HTML itself.

So use the <hr> tag without attributes, then style it in CSS to appear the way you want.

axios.get accepts a request config as the second parameter (not query string params).

You can use the params config option to set query string params as follows:

axios.get('/api', {
  params: {
    foo: 'bar'
  }
});

May be it will helpful:

<Border BorderBrush="Black" BorderThickness="1" HorizontalAlignment="Left" Height="160" Margin="10,55,0,0" VerticalAlignment="Top" Width="492"/>

You can use this: [None] * 10. But this won't be "fixed size" you can still append, remove ... This is how lists are made.

You could make it a tuple (tuple([None] * 10)) to fix its width, but again, you won't be able to change it (not in all cases, only if the items stored are mutable).

Another option, closer to your requirement, is not a list, but a collections.deque with a maximum length. It's the maximum size, but it could be smaller.

import collections
max_4_items = collections.deque([None] * 4, maxlen=4)

But, just use a list, and get used to the "pythonic" way of doing things.

I fixed the same problem with the below commands... Type python on your terminal. If you see python version 2.x then run these two commands to install pandas:

sudo python -m pip install wheel

and

sudo python -m pip install pandas

Else if you see python version 3.x then run these two commands to install pandas:

sudo python3 -m pip install wheel

and

sudo python3 -m pip install pandas

Good Luck!

System.Reflection.Assembly.GetExecutingAssembly().Location

When you type the FROM table those errors will disappear. Type FROM below what your typing then Intellisense will work and multi-part identifier will work.

memset requires you to import the header string.h file. So just add the following header

#include <string.h>
...

PRINT DATEDIFF(second,'2010-01-22 15:29:55.090','2010-01-22 15:30:09.153')

Converting Simple strings

The easiest way is to use the strconv.Atoi() function.

Note that there are many other ways. For example fmt.Sscan() and strconv.ParseInt() which give greater flexibility as you can specify the base and bitsize for example. Also as noted in the documentation of strconv.Atoi():

Atoi is equivalent to ParseInt(s, 10, 0), converted to type int.

Here's an example using the mentioned functions (try it on the Go Playground):

flag.Parse()
s := flag.Arg(0)

if i, err := strconv.Atoi(s); err == nil {
    fmt.Printf("i=%d, type: %T\n", i, i)
}

if i, err := strconv.ParseInt(s, 10, 64); err == nil {
    fmt.Printf("i=%d, type: %T\n", i, i)
}

var i int
if _, err := fmt.Sscan(s, &i); err == nil {
    fmt.Printf("i=%d, type: %T\n", i, i)
}

Output (if called with argument "123"):

i=123, type: int
i=123, type: int64
i=123, type: int

Parsing Custom strings

There is also a handy fmt.Sscanf() which gives even greater flexibility as with the format string you can specify the number format (like width, base etc.) along with additional extra characters in the input string.

This is great for parsing custom strings holding a number. For example if your input is provided in a form of "id:00123" where you have a prefix "id:" and the number is fixed 5 digits, padded with zeros if shorter, this is very easily parsable like this:

s := "id:00123"

var i int
if _, err := fmt.Sscanf(s, "id:%5d", &i); err == nil {
    fmt.Println(i) // Outputs 123
}

More compact version working with spaces and newlines in the file name:

find . -iname '*.txt' -exec sh -c 'echo "{}" ; ls -l "{}"' \;

rapidjson is a C++ JSON parser/generator designed to be fast and small memory footprint.

There is a performance comparison with YAJL and JsonCPP.

Update:

I created an open source project Native JSON benchmark, which evaluates 29 (and increasing) C/C++ JSON libraries, in terms of conformance and performance. This should be an useful reference.

I tried a bunch of these ideas to get HTTPS working, but the key for me was adding the protocol mapping. Here's what my server config file looks like, this works for both HTTP and HTTPS client connections:

  <system.serviceModel>
    <protocolMapping>
      <add scheme="https" binding="wsHttpBinding" bindingConfiguration="TransportSecurityBinding" />
    </protocolMapping>
    <services>
      <service name="FeatureService" behaviorConfiguration="HttpsBehavior">
        <endpoint address="soap" binding="wsHttpBinding" contract="MyServices.IFeature" bindingConfiguration="TransportSecurityBinding" />
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="HttpsBehavior">
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
        <behavior name="">
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="false" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <bindings>
      <wsHttpBinding>
        <binding name="TransportSecurityBinding" maxReceivedMessageSize="2147483647">
          <security mode="Transport">
            <transport clientCredentialType="None" />
          </security>
        </binding>
      </wsHttpBinding>
    </bindings>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
  </system.serviceModel>

Deleting the DLL (where the error is occurred) and re-building the solution fixed my problem. Thanks

As so many good answers said, an object must implement the Iterable interface if it wants to use a for-each loop.

I'll post a simple example and try to explain in a different way how a for-each loop works.

The for-each loop example:

public class ForEachTest {

    public static void main(String[] args) {

        List<String> list = new ArrayList<String>();
        list.add("111");
        list.add("222");

        for (String str : list) {
            System.out.println(str);
        }
    }
}

Then, if we use javap to decompile this class, we will get this bytecode sample:

public static void main(java.lang.String[]);
    flags: ACC_PUBLIC, ACC_STATIC
    Code:
      stack=2, locals=4, args_size=1
         0: new           #16                 // class java/util/ArrayList
         3: dup
         4: invokespecial #18                 // Method java/util/ArrayList."<init>":()V
         7: astore_1
         8: aload_1
         9: ldc           #19                 // String 111
        11: invokeinterface #21,  2           // InterfaceMethod java/util/List.add:(Ljava/lang/Object;)Z
        16: pop
        17: aload_1
        18: ldc           #27                 // String 222
        20: invokeinterface #21,  2           // InterfaceMethod java/util/List.add:(Ljava/lang/Object;)Z
        25: pop
        26: aload_1
        27: invokeinterface #29,  1           // InterfaceMethod java/util/List.iterator:()Ljava/util/Iterator;

As we can see from the last line of the sample, the compiler will automatically convert the use of for-each keyword to the use of an Iterator at compile time. That may explain why object, which doesn't implement the Iterable interface, will throw an Exception when it tries to use the for-each loop.

Mostly in Hibernate , need to add the Entity class in hibernate.cfg.xml like-

<hibernate-configuration>
  <session-factory>

    ....
    <mapping class="xxx.xxx.yourEntityName"/>
 </session-factory>
</hibernate-configuration>

There is an another way to see XML SOAP - custom MessageEncoder. The main difference from IClientMessageInspector is that it works on lower level, so it captures original byte content including any malformed xml.

In order to implement tracing using this approach you need to wrap a standard textMessageEncoding with custom message encoder as new binding element and apply that custom binding to endpoint in your config.

Also you can see as example how I did it in my project - wrapping textMessageEncoding, logging encoder, custom binding element and config.

DEVELOPER runs autoconf and automake:

1. autoconf -- creates shippable configure script
   (which the installer will later run to make the Makefile)

• ‘autoconf’ is a macro processor.
• It converts configure.ac, which is a shell script using macro instructions, into configure, a full-fledged shell script.

2. automake - creates shippable Makefile.in data file
   (which configure will later read to make the Makefile)

• Automake helps with creating portable and GNU-standard compliant Makefiles.
• ‘automake’ creates complex Makefile.ins from simple Makefile.ams

INSTALLER runs configure, make and sudo make install:

./configure       # Creates  Makefile        (from     Makefile.in).  
make              # Creates  the application (from the Makefile just created).  

sudo make install # Installs the application 
                  #   Often, by default its files are installed into /usr/local

INPUT/OUTPUT MAP

Notation below is roughly: inputs --> programs --> outputs

DEVELOPER runs these:

configure.ac -> autoconf -> configure (script) --- (*.ac = autoconf)
configure.in --> autoconf -> configure (script) --- (configure.in depreciated. Use configure.ac)

Makefile.am -> automake -> Makefile.in ----------- (*.am = automake)

INSTALLER runs these:

Makefile.in -> configure -> Makefile (*.in = input file)

Makefile -> make ----------> (puts new software in your downloads or temporary directory)
Makefile -> make install -> (puts new software in system directories)

"autoconf is an extensible package of M4 macros that produce shell scripts to automatically configure software source code packages. These scripts can adapt the packages to many kinds of UNIX-like systems without manual user intervention. Autoconf creates a configuration script for a package from a template file that lists the operating system features that the package can use, in the form of M4 macro calls."

"automake is a tool for automatically generating Makefile.in files compliant with the GNU Coding Standards. Automake requires the use of Autoconf."

Manuals:

• GNU AutoTools (The definitive manual on this stuff)

• m4 (used by autoconf)

• autoconf

• automake

Free online tutorials:

• Using GNU Autotools

Example:

The main configure.ac used to build LibreOffice is over 12k lines of code, (but there are also 57 other configure.ac files in subfolders.)

From this my generated configure is over 41k lines of code.

And while the Makefile.in and Makefile are both only 493 lines of code. (But, there are also 768 more Makefile.in's in subfolders.)

A simple and very usefull example, is....

Imagine:

you have a uint32_t array[2] and want to access the 3rd and 4th Byte of the Byte chain. you could do *((uint16_t*) &array[1]). But this sadly breaks the strict aliasing rules!

But known compilers allow you to do the following :

union un
{
    uint16_t array16[4];
    uint32_t array32[2];
}

technically this is still a violation of the rules. but all known standards support this usage.

You need to do something like this (If you want to call the method on page load):

new Vue({
    // ...
    methods:{
        getUnits: function() {...}
    },
    created: function(){
        this.getUnits()
    }
});

The problem for me was that the library project and the project using play services were in different directories. So just:

• 1.Add the files to the same workspace then remove the library.
• 2.Restart eclipse
• 3.Add the library project again
• 4.Clear

Nope, you've heard of MonoTouch which is a .NET/mono environment for iPhone development. But you still need a Mac and the official iPhone SDK. And the emulator is the official apple one, this acts as a separate IDE and allows you to not have to code in Objective C, rather you code in c#

It's an interesting project to say the least....

EDIT: apparently, you can distribute on the app store now, early on that was a no go....

Answering your question in this format is quite challenging.

On the other hand you ask about navigation and then about current $state acting all weird.

For the first I'd say it's too broad question and for the second I'd say... well, you are doing something wrong or missing the obvious :)

Take the following controller:

app.controller('MainCtrl', function($scope, $state) {
  $scope.state = $state;
});

Where app is configured as:

app.config(function($stateProvider) {
  $stateProvider
    .state('main', {
        url: '/main',
        templateUrl: 'main.html',
        controller: 'MainCtrl'
    })
    .state('main.thiscontent', {
        url: '/thiscontent',
        templateUrl: 'this.html',
        controller: 'ThisCtrl'
    })
    .state('main.thatcontent', {
        url: '/thatcontent',
        templateUrl: 'that.html'
    });
});

Then simple HTML template having

<div>
  {{ state | json }}
</div>

Would "print out" e.g. the following

{ 
  "params": {}, 
  "current": { 
    "url": "/thatcontent", 
    "templateUrl": "that.html", 
    "name": "main.thatcontent" 
  }, 
  "transition": null
}

I put up a small example showing this, using ui.router and pascalprecht.translate for the menus. I hope you find it useful and figure out what is it you are doing wrong.

Screencap

This might be caused by issue in your code. In my case, for instance,

I had Mongo database pointing to my local(done this for testing and forgot to update it back) instead of the one on EC2 which is the same machine 
        where war file is deployed to. 

How did I figured it out? I had to compare with older version of the code which works fine.

I installed Node.js on bluehost.com (a shared server) using:

wget <path to download file>
tar -xf <gzip file>
mv <gzip_file_dir> node

This will download the tar file, extract to a directory and then rename that directory to the name 'node' to make it easier to use.

then

./node/bin/npm install jt-js-sample

Returns:
npm WARN engine [email protected]: wanted: {"node":"0.10.x"} (current: {"node":"0.12.4","npm":"2.10.1"})
[email protected] node_modules/jt-js-sample
+-- [email protected] ([email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected])

I can now use the commands:

# ~/node/bin/node -v
v0.12.4

# ~/node/bin/npm -v
2.10.1

For security reasons, I have renamed my node directory to something else.

I would agree with @evillinux, It would be best to make your background image semi transparent so it supports < ie8

The other suggestions of using another div are also a great option, and it's the way to go if you want to do this in css. For example if the site had such features as selecting your own background color. I would suggest using a filter for older IE. eg:

filter:Alpha(opacity=50)

Try it

<!- HTML -->
<tr onmouseover="mOvr(this,'#ffa');" onmouseout="mOut(this,'#FFF');">

<script>
function mOvr(src,clrOver) { 
  if (!src.contains(event.fromElement)) { 
  src.bgColor = clrOver; 
  } 
} 
function mOut(src,clrIn) { 
  if (!src.contains(event.toElement)) { 
  src.bgColor = clrIn; 
  } 
} 
</script>

pip3 install selenium

Try this if you have python3.

The easy way: Pick an alternative Color Scheme:

Preferences > Color Scheme > ...pick one

The more complicated way: Edit the current color scheme file:

Preferences > Browse Packages > Color Scheme - Default > ... edit the Color Scheme file you are using:

Looking at the structure of the XML, drill down into dict > settings > settings > dict >

Look for the key (or add it if it's missing): lineHighlight. Add a string with an #RRGGBB or #RRGGBBAA format.

For those who use com.nhaarman.mockitokotlin2.mock {}

This error occurs when, for example, we create a mock inside another mock

mock {
    on { x() } doReturn mock {
        on { y() } doReturn z()
    }
}

The solution to this is to create the child mock in a variable and use the variable in the scope of the parent mock to prevent the mock creation from being explicitly nested.

val liveDataMock = mock {
        on { y() } doReturn z()
}
mock {
    on { x() } doReturn liveDataMock
}

A React Node is one of the following types:

• Boolean (which is ignored)
• null or undefined (which is ignored)
• Number
• String
• A React element (result of JSX)
• An array of any of the above, possibly a nested one

The quick and dirty way to check what string you need it to look at the generated .resources files.

Your .resources are generated in the resources projects obj/Debug directory. (if not right click on .resx file in solution explorer and hit 'Run Custom Tool' to generate the .resources files)

Navigate to this directory and have a look at the filenames. You should see a file ending in XYZ.resources. Copy that filename and remove the trailing .resources and that is the file you should be loading.

For example in my obj/Bin directory I have the file:

MyLocalisation.Properties.Resources.resources

If the resource files are in the same Class library/Application I would use the following C#

ResourceManager RM = new ResourceManager("MyLocalisation.Properties.Resources", Assembly.GetExecutingAssembly());

However, as it sounds like you are using the resources file from a separate Class library/Application you probably want

Assembly localisationAssembly = Assembly.Load("MyLocalisation");
ResourceManager RM =  new ResourceManager("MyLocalisation.Properties.Resources", localisationAssembly);

Once I packed JS code doing that to a tiny library:

https://github.com/AlexLibs/client-side-csv-generator

The Code, Documentation and Demo/Playground are provided on Github.

Enjoy :)

Pull requests are welcome.

There is no such functionality in jQuery. Use JSON.stringify or alternatively any jQuery plugin with similar functionality (e.g jquery-json).

here is the complete example of how you can select and upload multiple files in asp.net using file upload control....

write this code in .aspx file..

<head runat="server">
    <title></title>
</head>
<body>
<form id="form1" runat="server" enctype="multipart/form-data">
<div>
    <input type="file" id="myfile" multiple="multiple" name="myfile" runat="server" size="100" />
    <br />
    <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
    <br />
    <asp:Label ID="Span1" runat="server"></asp:Label>
</div>
</form>
</body>
</html>

after that write this code in .aspx.cs file..

   protected void Button1_Click(object sender,EventArgs e) {
          string filepath = Server.MapPath("\\Upload");
          HttpFileCollection uploadedFiles = Request.Files;
          Span1.Text = string.Empty;

          for(int i = 0;i < uploadedFiles.Count;i++) {
              HttpPostedFile userPostedFile = uploadedFiles[i];

              try {
                  if (userPostedFile.ContentLength > 0) {
                     Span1.Text += "<u>File #" + (i + 1) +  "</u><br>";
                     Span1.Text += "File Content Type: " +  userPostedFile.ContentType      + "<br>";
                     Span1.Text += "File Size: " + userPostedFile.ContentLength           + "kb<br>";
                     Span1.Text += "File Name: " + userPostedFile.FileName + "<br>";

                     userPostedFile.SaveAs(filepath + "\\" +    Path.GetFileName(userPostedFile.FileName));                  
                     Span1.Text += "Location where saved: " +   filepath + "\\" +   Path.GetFileName(userPostedFile.FileName) + "<p>";
                  }
              } catch(Exception Ex) {
                  Span1.Text += "Error: <br>" + Ex.Message;
              }
           }
        }
    }

and here you go...your multiple file upload control is ready..have a happy day.

It does matter, for example - there is a thing called character expansion

var s1 = "Strasse";
var s2 = "Straße";

s1.Equals(s2, StringComparison.Ordinal);           //false
s1.Equals(s2, StringComparison.InvariantCulture);  //true

With InvariantCulture the ß character gets expanded to ss.

What you've done doesn't work because you're binding an event to a function. As such, it's the event which defines the parameters that will be called when the event is raised (i.e. JavaScript doesn't know about your parameter in the function you've bound to onclick so can't pass anything into it).

You could do this however:

<input type="button" value="Click me" id="myButton"/>

<script type="text/javascript">

    var myButton = document.getElementById("myButton");

    var myMessage = "it's working";

    var myDelegate = function(message) {
        alert(message);
    }

    myButton.onclick = function() { 
        myDelegate(myMessage);
    };

</script>

You can also use showdialog

Private Sub Button3_Click(sender As System.Object, e As System.EventArgs) _
                      Handles Button3.Click

     dim mydialogbox as new aboutbox1
     aboutbox1.showdialog()

End Sub

Here is based on the answer from Mark Tolonen. The string included different languages of the word 'test' that's separated by '|', so you can see the difference.

u = u'ABCtestß???másbêta|test|??????|??|??|???|???????|???????|????????|ki?m tra|Ölçek|'
e8 = u.encode('utf-8')        # encode without BOM
e8s = u.encode('utf-8-sig')   # encode with BOM
e16 = u.encode('utf-16')      # encode with BOM
e16le = u.encode('utf-16le')  # encode without BOM
e16be = u.encode('utf-16be')  # encode without BOM
print('utf-8     %r' % e8)
print('utf-8-sig %r' % e8s)
print('utf-16    %r' % e16)
print('utf-16le  %r' % e16le)
print('utf-16be  %r' % e16be)
print()
print('utf-8  w/ BOM decoded with utf-8     %r' % e8s.decode('utf-8'))
print('utf-8  w/ BOM decoded with utf-8-sig %r' % e8s.decode('utf-8-sig'))
print('utf-16 w/ BOM decoded with utf-16    %r' % e16.decode('utf-16'))
print('utf-16 w/ BOM decoded with utf-16le  %r' % e16.decode('utf-16le'))

Here is a test run:

>>> u = u'ABCtestß???másbêta|test|??????|??|??|???|???????|???????|????????|ki?m tra|Ölçek|'

It's worth to know that only both utf-8-sig and utf-16 get back the original string after both encode and decode.

Well after doing some more searching I discovered the error may be related to other issues as invalid keystores, passwords etc.

I then remembered that I had set two VM arguments for when I was testing SSL for my network connectivity.

I removed the following VM arguments to fix the problem:

-Djavax.net.ssl.keyStore=mySrvKeystore -Djavax.net.ssl.keyStorePassword=123456

Note: this keystore no longer exists so that's probably why the Exception.

I'm sure you'll get a ton of "don't do this" answers, and I must say, there is good reason. This isn't an ideal solution....

That being said, I've gone down this road (and similar ones) before, mostly because the job specified it as a hard requirement and I couldn't talk around it.

Here are a few things to consider with this:

How easy is it to link to Access from Excel using ADO / DAO? Is it quite limited in terms of functionality or can I get creative?

It's fairly straitforward. You're more limited than you would be doing things using other tools, since VBA and Excel forms is a bit more limiting than most full programming languages, but there isn't anything that will be a show stopper. It works - sometimes its a bit ugly, but it does work. In my last company, I often had to do this - and occasionally was pulling data from Access and Oracle via VBA in Excel.

Do I pay a performance penalty (vs.using forms in Access as the UI)?

My experience is that there is definitely a perf. penalty in doing this. I never cared (in my use case, things were small enough that it was reasonable), but going Excel<->Access is a lot slower than just working in Access directly. Part of it depends on what you want to do....

In my case, the thing that seemed to be the absolute slowest (and most painful) was trying to fill in Excel spreadsheets based on Access data. This wasn't fun, and was often very slow. If you have to go down this road, make sure to do everything with Excel hidden/invisible, or the redrawing will absolutely kill you.

Assuming that the database will always be updated using ADO / DAO commands from within Excel VBA, does that mean I can have multiple Excel users using that one single Access database and not run into any concurrency issues etc.?

You're pretty much using Excel as a client - the same way you would use a WinForms application or any other tool. The ADO/DAO clients for Access are pretty good, so you probably won't run into any concurrency issues.

That being said, Access does NOT scale well. This works great if you have 2 or 3 (or even 10) users. If you are going to have 100, you'll probably run into problems. Also, I tended to find that Access needed regular maintenance in order to not have corruption issues. Regular backups of the Access DB are a must. Compacting the access database on a regular basis will help prevent database corruption, in my experience.

Any other things I should be aware of?

You're doing this the hard way. Using Excel to hit Access is going to be a lot more work than just using Access directly.

I'd recommend looking into the Access VBA API - most of it is the same as Excel, so you'll have a small learning curve. The parts that are different just make this easier. You'll also have all of the advantages of Access reporting and Forms, which are much more data-oriented than the ones in Excel. The reporting can be great for things like this, and having the Macros and Reports will make life easier in the long run. If the user's going to be using forms to manage everything, doing the forms in Access will be very, very similar to doing them in Excel, and will look nearly identical, but will make everything faster and smoother.

heres a jquery plugin to do that

(function($) {
    $.fn.onEnter = function(func) {
        this.bind('keypress', function(e) {
            if (e.keyCode == 13) func.apply(this, [e]);    
        });               
        return this; 
     };
})(jQuery);

to use it, include the code and set it up like this:

$( function () {
    console.log($("input"));
    $("input").onEnter( function() {
        $(this).val("Enter key pressed");                
    });
});

A comparison between the different Visual Studio Express editions can be found at Visual Studio Express (archive.org link). The difference between Windows and Windows Desktop is that with the Windows edition you can build Windows Store Apps (using .NET, WPF/XAML) while the Windows Desktop edition allows you to write classic Windows Desktop applications. It is possible to install both products on the same machine.

Visual Studio Express 2010 allows you to build Windows Desktop applications. Writing Windows Store applications is not possible with this product.

For learning I would suggest Notepad and the command line. While an IDE provides significant productivity enhancements to professionals, it can be intimidating to a beginner. If you want to use an IDE nevertheless I would recommend Visual Studio Express 2013 for Windows Desktop.

This is called programming to interface. This will be helpful in case if you wish to move to some other implementation of List in the future. If you want some methods in ArrayList then you would need to program to the implementation that is ArrayList a = new ArrayList().

Heads up,

JAVASCRIPT

<script>
   function readMtlAtClient(){

       mtlFileContent = '';

       var mtlFile = document.getElementById('mtlFileInput').files[0];
       var readerMTL = new FileReader();

       // Closure to capture the file information.
       readerMTL.onload = (function(reader) {
           return function() {
               mtlFileContent = reader.result;
               mtlFileContent = mtlFileContent.replace('data:;base64,', '');
               mtlFileContent = window.atob(mtlFileContent);

           };
       })(readerMTL);

       readerMTL.readAsDataURL(mtlFile);
   }
</script>

HTML

    <input class="FullWidth" type="file" name="mtlFileInput" value="" id="mtlFileInput" 
onchange="readMtlAtClient()" accept=".mtl"/>

Then mtlFileContent has your text as a decoded string !

Its possible using pseudo element (after).
I have added to the original code a

  border-color: #567498;
  border-spacing:10px;
  position:relative;
  background:#000;
}
#content:after {
  content: '';
  position: absolute;
  top: -15px;
  left: -15px;
  right: -15px;
  bottom: -15px;
  border: red 2px solid;
}

In case anyone is wondering what input value

<input (keydown.enter)="search($event.target.value)" />

I ran into this problem on Windows, where calling exec and spawn with the exact same command (omitting arguments) worked fine for exec (so I knew my command was on $PATH), but spawn would give ENOENT. Turned out that I just needed to append .exe to the command I was using:

import { exec, spawn } from 'child_process';

// This works fine
exec('p4 changes -s submitted');

// This gives the ENOENT error
spawn('p4');

// But this resolves it
spawn('p4.exe');
// Even works with the arguments now
spawn('p4.exe', ['changes', '-s', 'submitted']);

What about SYSDATE() ?

<?php
  $db = mysql_connect('localhost','user','pass');
  mysql_select_db('test_db');

  $stmt = "INSERT INTO `test` (`first`,`last`,`whenadded`) VALUES ".
          "('{$first}','{$last}','SYSDATE())";
  $rslt = mysql_query($stmt);
?>

Look at Difference between NOW(), SYSDATE() & CURRENT_DATE() in MySQL for more info about NOW() and SYSDATE().

Use calendar.monthrange:

>>> from calendar import monthrange
>>> monthrange(2011, 2)
(1, 28)

Just to be clear, monthrange supports leap years as well:

>>> from calendar import monthrange
>>> monthrange(2012, 2)
(2, 29)

As @mikhail-pyrev mentions in a comment:

First number is weekday of first day of the month, second number is number of days in said month.

Let me just add a warning to all the existing answers:

When using the SELECT ... FROM syntax, you should keep in mind that it is proprietary syntax for T-SQL and is non-deterministic. The worst part is, that you get no warning or error, it just executes smoothly.

Full explanation with example is in the documentation:

Use caution when specifying the FROM clause to provide the criteria for the update operation. The results of an UPDATE statement are undefined if the statement includes a FROM clause that is not specified in such a way that only one value is available for each column occurrence that is updated, that is if the UPDATE statement is not deterministic.

At the beginning of your data frame include stringsAsFactors = FALSE to ignore all misunderstandings.

Another option:

if( ![string]::IsNullOrEmpty($user_sam) -and ![string]::IsNullOrEmpty($user_case) )
{
   ...
}

You could try something like this:

...Binding="{Binding RelativeSource={RelativeSource FindAncestor, 
AncestorType={x:Type Window}}, Path=DataContext.AllowItemCommand}" ...

If you want to encode URI path components, you can also use standard JDK functions, e.g.

public static String encodeURLPathComponent(String path) {
    try {
        return new URI(null, null, path, null).toASCIIString();
    } catch (URISyntaxException e) {
        // do some error handling
    }
    return "";
}

The URI class can also be used to encode different parts of or whole URIs.

I figured out myself.

cmp calls ComputeBetasAndNuHat which returns a list which has objective as minusloglik

So I can change the function cmp to get this value.

Predicate falls under the category of generic delegates in C#. This is called with one argument and always return the boolean type. Basically, the predicate is used to test the condition - true/false. Many classes support predicate as an argument. For example, list.findall expects the parameter predicate. Here is an example of predicate.

Imagine a function pointer with the signature:

<modifier> bool delegate myDelegate<in T>(T match);

Here is the example:

Node.cs:

namespace PredicateExample
{
    class Node
    {
        public string Ip_Address { get; set; }
        public string Node_Name { get; set; }
        public uint Node_Area { get; set; }
    }
}

Main class:

using System;
using System.Threading;
using System.Collections.Generic;

namespace PredicateExample
{
    class Program
    {
        static void Main(string[] args)
        {
            Predicate<Node> backboneArea = Node =>  Node.Node_Area == 0 ;
            List<Node> Nodes = new List<Node>();
            Nodes.Add(new Node { Ip_Address = "1.1.1.1", Node_Area = 0, Node_Name = "Node1" });
            Nodes.Add(new Node { Ip_Address = "2.2.2.2", Node_Area = 1, Node_Name = "Node2" });
            Nodes.Add(new Node { Ip_Address = "3.3.3.3", Node_Area = 2, Node_Name = "Node3" });
            Nodes.Add(new Node { Ip_Address = "4.4.4.4", Node_Area = 0, Node_Name = "Node4" });
            Nodes.Add(new Node { Ip_Address = "5.5.5.5", Node_Area = 1, Node_Name = "Node5" });
            Nodes.Add(new Node { Ip_Address = "6.6.6.6", Node_Area = 0, Node_Name = "Node6" });
            Nodes.Add(new Node { Ip_Address = "7.7.7.7", Node_Area = 2, Node_Name = "Node7" });

            foreach( var item in Nodes.FindAll(backboneArea))
            {
                Console.WriteLine("Node Name " + item.Node_Name + " Node IP Address " + item.Ip_Address);
            }

            Console.ReadLine();
        }
    }
}

Leaving this here for info,

This error can also be caused if PostgreSQL server is on another machine and is not listening on external interfaces.

To debug this specific problem, you can follow theses steps:

• Look at your postgresql.conf, sudo vim /etc/postgresql/9.3/main/postgresql.conf
• Add this line: listen_addresses = '*'
• Restart the service sudo /etc/init.d/postgresql restart

(Note, the commands above are for ubuntu. Other linux distro or OS may have different path to theses files)

Note: using '*' for listening addresses will listen on all interfaces. If you do '0.0.0.0' then it'll listen for all ipv4 and if you do '::' then it'll listen for all ipv6.

If your DBMS doesn't support distinct with multiple columns like this:

select distinct(col1, col2) from table

Multi select in general can be executed safely as follows:

select distinct * from (select col1, col2 from table ) as x

As this can work on most of the DBMS and this is expected to be faster than group by solution as you are avoiding the grouping functionality.

You need to call repaint() and revalidate(). The former tells Swing that an area of the window is dirty (which is necessary to erase the image of the old children removed by removeAll()); the latter tells the layout manager to recalculate the layout (which is necessary when adding components). This should cause children of the panel to repaint, but may not cause the panel itself to do so (see this for the list of repaint triggers).

On a more general note: rather than reusing the original panel, I'd recommend building a new panel and swapping them at the parent.

Here's an example:

class RenameOldTableToNewTable < ActiveRecord::Migration
  def self.up
    rename_table :old_table_name, :new_table_name
  end

  def self.down
    rename_table :new_table_name, :old_table_name
  end
end

I had to go and rename the model declaration file manually.

Edit:

In Rails 3.1 & 4, ActiveRecord::Migration::CommandRecorder knows how to reverse rename_table migrations, so you can do this:

class RenameOldTableToNewTable < ActiveRecord::Migration
  def change
    rename_table :old_table_name, :new_table_name
  end 
end

(You still have to go through and manually rename your files.)

If you can use the jQuery validation plugin you can do it like so:

Html:

JavaScript:

$.validator.addMethod('imagedim', function(value, element, param) {
  var _URL = window.URL;
        var  img;
        if ((element = this.files[0])) {
            img = new Image();
            img.onload = function () {
                console.log("Width:" + this.width + "   Height: " + this.height);//this will give you image width and height and you can easily validate here....

                return this.width >= param
            };
            img.src = _URL.createObjectURL(element);
        }

You can do it this with two replace's

//let stw be "John Smith $100,000.00 M"

sb_trim = Regex.Replace(stw, @"\s+\$|\s+(?=\w+$)", ",");
//sb_trim becomes "John Smith,100,000.00,M"

sb_trim = Regex.Replace(sb_trim, @"(?<=\d),(?=\d)|[.]0+(?=,)", "");
//sb_trim becomes "John Smith,100000,M"

sw.WriteLine(sb_trim);

This is my code .This works for me

componentDidMount(){
        axios.get('http://localhost:5000/supplier').then(
            response => {
                console.log(response)
                this.setState({suppliers:response.data.data})
            }
        )
        .catch(error => {
            console.log(error)
        })
        
    }

componentDidUpdate(){
        this.componentDidMount();
}

window.location.reload(); I think this thing is not good for react js

When you killed the session, the session hangs around for a while in "KILLED" status while Oracle cleans up after it.

If you absolutely must, you can kill the OS process as well (look up v$process.spid), which would release any locks it was holding on to.

See this for more detailed info.
