There are a few tools around that are quite good. Here is a summary of some of the Java ones.

Some good static analysis tools include FindBugs (gives some useful hints), JLint, Java Pathfinder (JPF & JPF2), and Bogor.

MultithreadedTC is quite a good dynamic analysis tool (integrated into JUnit) where you have to set up your own test cases.

ConTest from IBM Research is interesting. It instruments your code by inserting all kinds of thread modifying behaviours (e.g. sleep & yield) to try to uncover bugs randomly.

SPIN is a really cool tool for modelling your Java (and other) components, but you need to have some useful framework. It is hard to use as is, but extremely powerful if you know how to use it. Quite a few tools use SPIN underneath the hood.

MultithreadedTC is probably the most mainstream, but some of the static analysis tools listed above are definitely worth looking at.

Agile is a general philosophy regarding software production, Scrum is an implementation of that philosophy pertaining specifically to project management.

When you compile your program the reference variable of the base class gets memory and compiler checks all the methods in that class. So it checks all the base class methods but not the child class methods. Now at runtime when the object is created, only checked methods can run. In case a method is overridden in the child class that function runs. Child class other functions aren't run because the compiler hasn't recognized them at the compile time.

I'm using apache-tomcat-7.0.70 with jdk1.7.0_45 and none of the solutions here and elsewhere on stackoverflow worked for me. Just sharing this solution as it hopefully might help someone as this is very high on Google's search

What worked is doing BOTH of these steps:

1. Starting my tomcat with "export JAVA_OPTS="$JAVA_OPTS -Dhttps.protocols=TLSv1.2" by adding it to tomcat/bin/setenv.sh (Syntax slightly different on Windows)

2. Manually building/forcing HttpClients or anything else you need with the TLS1.2 protocol:

   Context ctx = SSLContexts.custom().useProtocol("TLSv1.2").build();
   HttpClient httpClient = HttpClientBuilder.create().setSslcontext(ctx).build();
   HttpPost httppost = new HttpPost(scsTokenVerificationUrl);
   
   List<NameValuePair> paramsAccessToken = new ArrayList<NameValuePair>(2);
   paramsAccessToken.add(new BasicNameValuePair("token", token));
   paramsAccessToken.add(new BasicNameValuePair("client_id", scsClientId));
   paramsAccessToken.add(new BasicNameValuePair("secret", scsClientSecret));
   httppost.setEntity(new UrlEncodedFormEntity(paramsAccessToken, "utf-8"));
   
   //Execute and get the response.
   HttpResponse httpResponseAccessToken = httpClientAccessToken.execute(httppost);
   
   String responseJsonAccessToken = EntityUtils.toString(httpResponseAccessToken.getEntity());
   

You can use the statement :-

Class c = s.getClass();

To get the class instance.

There are multiple ways of doing that you can use either place or grid or even the packmethod.

Sample code:

from tkinter import *
root = Tk()

l = Label(root, text="hello" )
l.pack(padx=6, pady=4) # where padx and pady represent the x and y axis respectively
# well you can also use side=LEFT inside the pack method of the label widget.

To place a widget to on basis of columns and rows , use the grid method:

but = Button(root, text="hello" )
but.grid(row=0, column=1)

Flex-boxes are the solution - and they're fantastic. I've been wanting something like this out of css for a decade. All you need is to add display: flex to your style for "Main" and flex-grow: 100 (where 100 is arbitrary - its not important that it be exactly 100). Try adding this style (colors added to make the effect visible):

<style>
    #Main {
        background-color: lightgray;
        display: flex;
    }

    #div1 {
        border: 1px solid green;   
        height: 50px; 
        display: inline-flex; 
    }
    #div2 {
        border: 1px solid blue;    
        height: 50px;
        display: inline-flex;
        flex-grow: 100;
    }
    #div3 {
        border: 1px solid orange;        
        height: 50px;
        display: inline-flex;
    }
</style>

If you use the request body in a GET request, you're breaking the REST principle, because your GET request won't be able to be cached, because cache system uses only the URL.

What's worse, your URL can't be bookmarked, because the URL doesn't contain all the information needed to redirect the user to this page.

Use URL or Query parameters instead of request body parameters, e.g.:

/myapp?var1=xxxx&var2=xxxx
/myapp;var1=xxxx/resource;var2=xxxx 

In fact, the HTTP RFC 7231 says that:

A payload within a GET request message has no defined semantics; sending a payload body on a GET request might cause some existing implementations to reject the request.

For more information take a look here.

"no suitable driver" usually means that the syntax for the connection URL is incorrect.

You should try to do this, whenever it is appropriate. Besides serving to warn you when you "accidentally" try to modify a value, it provides information to the compiler that can lead to better optimization of the class file. This is one of the points in the book, "Hardcore Java" by Robert Simmons, Jr. In fact, the book spends all of its second chapter on the use of final to promote optimizations and prevent logic errors. Static analysis tools such as PMD and the built-in SA of Eclipse flag these sorts of cases for this reason.

Greg Hewgill's answer is great but if you need more nodes per level you can use a list|dictionary to create them: And then use method to access them either by name or order (like id)

class node(object):
    def __init__(self):
        self.name=None
        self.node=[]
        self.otherInfo = None
        self.prev=None
    def nex(self,child):
        "Gets a node by number"
        return self.node[child]
    def prev(self):
        return self.prev
    def goto(self,data):
        "Gets the node by name"
        for child in range(0,len(self.node)):
            if(self.node[child].name==data):
                return self.node[child]
    def add(self):
        node1=node()
        self.node.append(node1)
        node1.prev=self
        return node1

Now just create a root and build it up: ex:

tree=node()  #create a node
tree.name="root" #name it root
tree.otherInfo="blue" #or what ever 
tree=tree.add() #add a node to the root
tree.name="node1" #name it

    root
   /
child1

tree=tree.add()
tree.name="grandchild1"

       root
      /
   child1
   /
grandchild1

tree=tree.prev()
tree=tree.add()
tree.name="gchild2"

          root
           /
        child1
        /    \
grandchild1 gchild2

tree=tree.prev()
tree=tree.prev()
tree=tree.add()
tree=tree.name="child2"

              root
             /   \
        child1  child2
       /     \
grandchild1 gchild2


tree=tree.prev()
tree=tree.goto("child1") or tree=tree.nex(0)
tree.name="changed"

              root
              /   \
         changed   child2
        /      \
  grandchild1  gchild2

That should be enough for you to start figuring out how to make this work

To install a specific python package version whether it is the first time, an upgrade or a downgrade use:

pip install --force-reinstall MySQL_python==1.2.4

MySQL_python version 1.2.2 is not available so I used a different version. To view all available package versions from an index exclude the version:

pip install MySQL_python==

Sometimes "Nothing to be done for all" error can be caused by spaces before command in makefile rule instead of tab. Please ensure that you use tabs instead of spaces inside of your rules.

all:
<\t>$(CC) $(CFLAGS) ...

instead of

all:
    $(CC) $(CFLAGS) ...

Please see the GNU make manual for the rule syntax description: https://www.gnu.org/software/make/manual/make.html#Rule-Syntax

If you don't hope to sort the collections and you need the result that ["A" "B" "C"] is not equals to ["B" "B" "A" "C"],

l1.containsAll(l2)&&l2.containsAll(l1)

is not enough, you propably need to check the size too :

    List<String> l1 =Arrays.asList("A","A","B","C");
    List<String> l2 =Arrays.asList("A","B","C");
    List<String> l3 =Arrays.asList("A","B","C");

    System.out.println(l1.containsAll(l2)&&l2.containsAll(l1));//cautions, this will be true
    System.out.println(isListEqualsWithoutOrder(l1,l2));//false as expected

    System.out.println(l3.containsAll(l2)&&l2.containsAll(l3));//true as expected
    System.out.println(isListEqualsWithoutOrder(l2,l3));//true as expected


    public static boolean isListEqualsWithoutOrder(List<String> l1, List<String> l2) {
        return l1.size()==l2.size() && l1.containsAll(l2)&&l2.containsAll(l1);
}

How about using overloaded ArrayList constructor.

 private ArrayList<String> symbolsPresent = new ArrayList<String>(Arrays.asList(new String[] {"One","Two","Three","Four"}));

You can run your file in http-server.

1> Have Node.js installed in your system.

2> In CMD, run the command npm install http-server -g

3> Navigate to the specific path of your file folder in CMD and run the command http-server

4> Go to your browser and type localhost:8080. Your Application should run there.

Thanks:)

you may try the following code:

mainWindow = new BrowserWindow({
        webPreferences: {
            nodeIntegration:false,
        }
});

Solved! The call build job: project, parameters: params fails with an error java.lang.UnsupportedOperationException: must specify $class with an implementation of interface java.util.List when params = [:]. Replacing it with params = null solved the issue. Here the working code below.

def doCopyMibArtefactsHere(projectName) {
    step ([
        $class: 'CopyArtifact',
        projectName: projectName,
        filter: '**/**.mib',
        fingerprintArtifacts: true, 
        flatten: true
    ]);
}

def BuildAndCopyMibsHere(projectName, params = null) {
    build job: project, parameters: params
    doCopyMibArtefactsHere(projectName)
}
node { 
    stage('Prepare Mib'){
        BuildAndCopyMibsHere('project1')
    }
}

for column in df:
    print(df[column])

CROSS JOIN

AThe CROSS JOIN is meant to generate a Cartesian Product.

A Cartesian Product takes two sets A and B and generates all possible permutations of pair records from two given sets of data.

For instance, assuming you have the following ranks and suits database tables:

And the ranks has the following rows:

| name  | symbol | rank_value |
|-------|--------|------------|
| Ace   | A      | 14         |
| King  | K      | 13         |
| Queen | Q      | 12         |
| Jack  | J      | 11         |
| Ten   | 10     | 10         |
| Nine  | 9      |  9         |

While the suits table contains the following records:

| name    | symbol |
|---------|--------|
| Club    | ?      |
| Diamond | ?      |
| Heart   | ?      |
| Spade   | ?      |

As CROSS JOIN query like the following one:

SELECT
   r.symbol AS card_rank,
   s.symbol AS card_suit
FROM
   ranks r
CROSS JOIN
   suits s

will generate all possible permutations of ranks and suites pairs:

| card_rank | card_suit |
|-----------|-----------|
| A         | ?         |
| A         | ?         |
| A         | ?         |
| A         | ?         |
| K         | ?         |
| K         | ?         |
| K         | ?         |
| K         | ?         |
| Q         | ?         |
| Q         | ?         |
| Q         | ?         |
| Q         | ?         |
| J         | ?         |
| J         | ?         |
| J         | ?         |
| J         | ?         |
| 10        | ?         |
| 10        | ?         |
| 10        | ?         |
| 10        | ?         |
| 9         | ?         |
| 9         | ?         |
| 9         | ?         |
| 9         | ?         |

INNER JOIN

On the other hand, INNER JOIN does not return the Cartesian Product of the two joining data sets.

Instead, the INNER JOIN takes all elements from the left-side table and matches them against the records on the right-side table so that:

• if no record is matched on the right-side table, the left-side row is filtered out from the result set
• for any matching record on the right-side table, the left-side row is repeated as if there was a Cartesian Product between that record and all its associated child records on the right-side table.

For instance, assuming we have a one-to-many table relationship between a parent post and a child post_comment tables that look as follows:

Now, if the post table has the following records:

| id | title     |
|----|-----------|
| 1  | Java      |
| 2  | Hibernate |
| 3  | JPA       |

and the post_comments table has these rows:

| id | review    | post_id |
|----|-----------|---------|
| 1  | Good      | 1       |
| 2  | Excellent | 1       |
| 3  | Awesome   | 2       |

An INNER JOIN query like the following one:

SELECT
   p.id AS post_id,
   p.title AS post_title,
   pc.review  AS review
FROM post p
INNER JOIN post_comment pc ON pc.post_id = p.id

is going to include all post records along with all their associated post_comments:

| post_id | post_title | review    |
|---------|------------|-----------|
| 1       | Java       | Good      |
| 1       | Java       | Excellent |
| 2       | Hibernate  | Awesome   |

Basically, you can think of the INNER JOIN as a filtered CROSS JOIN where only the matching records are kept in the final result set.

Python

element.get_attribute("attribute name")

Java

element.getAttribute("attribute name")

Ruby

element.attribute("attribute name")

C#

element.GetAttribute("attribute name");

Use python-textops package :

from textops import *

'oldfile.txt' | cat() | grepv('bad') | tofile('newfile.txt')

xcopy.exe is the solution here. It's built into Windows.

xcopy /s c:\Folder1 d:\Folder2

I got here just by accident and the OP's question got my attention. Unfortunately I do not understand any of the explanations from the top. Seems to me like everybody knows it, gets it, accetps it, just cannot explain.

Luckily, a pure sentence from PHP documentation on foreach makes this completely clear:

Warning: Reference of a $value and the last array element remain even after the foreach loop. It is recommended to destroy it by unset().

Have a look at the Requests exception docs. In short:

In the event of a network problem (e.g. DNS failure, refused connection, etc), Requests will raise a ConnectionError exception.

In the event of the rare invalid HTTP response, Requests will raise an HTTPError exception.

If a request times out, a Timeout exception is raised.

If a request exceeds the configured number of maximum redirections, a TooManyRedirects exception is raised.

All exceptions that Requests explicitly raises inherit from requests.exceptions.RequestException.

To answer your question, what you show will not cover all of your bases. You'll only catch connection-related errors, not ones that time out.

What to do when you catch the exception is really up to the design of your script/program. Is it acceptable to exit? Can you go on and try again? If the error is catastrophic and you can't go on, then yes, you may abort your program by raising SystemExit (a nice way to both print an error and call sys.exit).

You can either catch the base-class exception, which will handle all cases:

try:
    r = requests.get(url, params={'s': thing})
except requests.exceptions.RequestException as e:  # This is the correct syntax
    raise SystemExit(e)

Or you can catch them separately and do different things.

try:
    r = requests.get(url, params={'s': thing})
except requests.exceptions.Timeout:
    # Maybe set up for a retry, or continue in a retry loop
except requests.exceptions.TooManyRedirects:
    # Tell the user their URL was bad and try a different one
except requests.exceptions.RequestException as e:
    # catastrophic error. bail.
    raise SystemExit(e)

As Christian pointed out:

If you want http errors (e.g. 401 Unauthorized) to raise exceptions, you can call Response.raise_for_status. That will raise an HTTPError, if the response was an http error.

An example:

try:
    r = requests.get('http://www.google.com/nothere')
    r.raise_for_status()
except requests.exceptions.HTTPError as err:
    raise SystemExit(err)

Will print:

404 Client Error: Not Found for url: http://www.google.com/nothere

Create a "module" object and declare variables in there. Unlike class-objects that have to be instantiated each time, the module objects are always available. Therefore, a public variable, function, or property in a "module" will be available to all the other objects in the VBA project, macro, Excel formula, or even within a MS Access JET-SQL query def.

We are used to

class ClassTypeA implements InterfaceTypeA {}
class ClassTypeB extends ClassTypeA {}

and any slight deviation from these rules greatly confuses us.

The syntax of a type bound is defined as

TypeBound:
    extends TypeVariable 
    extends ClassOrInterfaceType {AdditionalBound}

^{(JLS 12 > 4.4. Type Variables > TypeBound)}

If we were to change it, we would surely add the implements case

TypeBound:
    extends TypeVariable 
    extends ClassType {AdditionalBound}
    implements InterfaceType {AdditionalBound}

and end up with two identically processed clauses

ClassOrInterfaceType:
    ClassType 
    InterfaceType

^{(JLS 12 > 4.3. Reference Types and Values > ClassOrInterfaceType)}

except we would also need to take care of implements, which would complicate things further.

I believe it's the main reason why extends ClassOrInterfaceType is used instead of extends ClassType and implements InterfaceType - to keep things simple within the complicated concept. The problem is we don't have the right word to cover both extends and implements and we definitely don't want to introduce one.

<T is ClassTypeA>
<T is InterfaceTypeA>

Although extends brings some mess when it goes along with an interface, it's a broader term and it can be used to describe both cases. Try to tune your mind to the concept of extending a type (not extending a class, not implementing an interface). You restrict a type parameter by another type and it doesn't matter what that type actually is. It only matters that it's its upper bound and it's its supertype.

What has happened here is that Xcode has mysteriously added a "Framework Search Paths" entry that points to a particular iPhone device SDK. For example, mine was recently set to:

$(DEVELOPER_DIR)/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.2.1.sdk/System/Library/Frameworks

This leads the compiler to find frameworks of the incorrect architecture. Removing any values under the "Framework Search Paths" key in your target's build settings will resolve the issue.

On SmtpClient there is an EnableSsl property that you would set.

i.e.

SmtpClient client = new SmtpClient(exchangeServer);
client.EnableSsl = true;
client.Send(msg);

Previous answer is not correct in my experience, you can't pass it a simple string, needs to be a datetime object. So:

import datetime 
df.loc[datetime.date(year=2014,month=1,day=1):datetime.date(year=2014,month=2,day=1)]

Why not just use atoi? For example:

char myarray[4] = {'-','1','2','3'};

int i = atoi(myarray);

printf("%d\n", i);

Gives me, as expected:

-123

Update: why not - the character array is not null terminated. Doh!

You could use the nth-child pseudo-selector. For example:

table.align-right-3rd-column td:nth-child(3)
{
  text-align: right;
}

Then in your table do:

<table class="align-right-3rd-column">
  <tr>
    <td></td><td></td><td></td>
    ...
  </tr>
</table>

Edit:

Unfortunately, this only works in Firefox 3.5. However, if your table only has 3 columns, you could use the sibling selector, which has much better browser support. Here's what the style sheet would look like:

table.align-right-3rd-column td + td + td
{
  text-align: right;
}

This will match any column preceded by two other columns.

This generates a consistent hash based on any number of params passed in:

/**
 * Generates a hash from params passed in
 * @returns {string} hash based on params
 */
function fastHashParams() {
    var args = Array.prototype.slice.call(arguments).join('|');
    var hash = 0;
    if (args.length == 0) {
        return hash;
    }
    for (var i = 0; i < args.length; i++) {
        var char = args.charCodeAt(i);
        hash = ((hash << 5) - hash) + char;
        hash = hash & hash; // Convert to 32bit integer
    }
    return String(hash);
}

fastHashParams('hello world') outputs "990433808"

fastHashParams('this',1,'has','lots','of','params',true) outputs "1465480334"

pathlib module, introduced in Python 3.4 (PEP 428 — The pathlib module — object-oriented filesystem paths), makes path-related experience much much better.

$ pwd
/home/skovorodkin/stack
$ tree
.
+-- scripts
    +-- 1.py
    +-- 2.py

In order to get current working directory use Path.cwd():

from pathlib import Path

print(Path.cwd())  # /home/skovorodkin/stack

To get an absolute path to your script file, use Path.resolve() method:

print(Path(__file__).resolve())  # /home/skovorodkin/stack/scripts/1.py

And to get path of a directory where your script is located, access .parent (it is recommended to call .resolve() before .parent):

print(Path(__file__).resolve().parent)  # /home/skovorodkin/stack/scripts

Remember that __file__ is not reliable in some situations: How do I get the path of the current executed file in Python?.

Please note, that Path.cwd(), Path.resolve() and other Path methods return path objects (PosixPath in my case), not strings. In Python 3.4 and 3.5 that caused some pain, because open built-in function could only work with string or bytes objects, and did not support Path objects, so you had to convert Path objects to strings or use Path.open() method, but the latter option required you to change old code:

$ cat scripts/2.py
from pathlib import Path

p = Path(__file__).resolve()

with p.open() as f: pass
with open(str(p)) as f: pass
with open(p) as f: pass

print('OK')

$ python3.5 scripts/2.py
Traceback (most recent call last):
  File "scripts/2.py", line 11, in <module>
    with open(p) as f:
TypeError: invalid file: PosixPath('/home/skovorodkin/stack/scripts/2.py')

As you can see open(p) does not work with Python 3.5.

PEP 519 — Adding a file system path protocol, implemented in Python 3.6, adds support of PathLike objects to open function, so now you can pass Path objects to open function directly:

$ python3.6 scripts/2.py
OK

Thanks to @a_horse_with_no_name's comment, I changed my PGPORT definition to 5432 in pg_env.sh. That fixed the problem for me. I don't know why postgres set it as 5433 initially when it was hosting the service at 5432.

I would use a list:

string = []
for i in range(0, 9):
  string.append("Hello")

This way, you would have 9 "Hello" and you could get them individually like this:

string[x]

Where x would identify which "Hello" you want.

So, print(string[1]) would print Hello.

Here are the steps to use ASP.NET MVC 5 in Visual Studio 2012:

• Start your ASP.NET MVC 4 project.
• Install-Package Microsoft.AspNet.WebApi -pre
• Install-Package Microsoft.AspNet.Mvc -Pre
• Install-Package Microsoft.AspNet.SignalR -Pre

These two will update:

• Microsoft.AspNet.Mvc 5.0.0-rc1
• Microsoft.AspNet.Razor
• Microsoft.AspNet.WebApi 5.0.0-rc1
• Microsoft.AspNet.WebApi.Client 5.0.0-rc1
• Microsoft.AspNet.WebApi.Core 5.0.0-rc1
• Microsoft.AspNet.WebApi.WebHost 5.0.0-rc1
• Microsoft.AspNet.WebPages 3.0.0-rc1
• and some other goodies

If these upgrades did not update your web.config, then check out this useful page: upgrading from MVC4 to MVC5.

The cunningly-named urlencode() and urldecode().

However, you shouldn't need to use urldecode() on variables that appear in $_POST and $_GET.

you could search with aptitude search intl after you can choose the right one, for example sudo aptitude install php-intl and finally sudo service apache2 restart

good Luck!

You can specify formal arguments in rake by adding symbol arguments to the task call. For example:

require 'rake'

task :my_task, [:arg1, :arg2] do |t, args|
  puts "Args were: #{args} of class #{args.class}"
  puts "arg1 was: '#{args[:arg1]}' of class #{args[:arg1].class}"
  puts "arg2 was: '#{args[:arg2]}' of class #{args[:arg2].class}"
end

task :invoke_my_task do
  Rake.application.invoke_task("my_task[1, 2]")
end

# or if you prefer this syntax...
task :invoke_my_task_2 do
  Rake::Task[:my_task].invoke(3, 4)
end

# a task with prerequisites passes its 
# arguments to it prerequisites
task :with_prerequisite, [:arg1, :arg2] => :my_task #<- name of prerequisite task

# to specify default values, 
# we take advantage of args being a Rake::TaskArguments object
task :with_defaults, :arg1, :arg2 do |t, args|
  args.with_defaults(:arg1 => :default_1, :arg2 => :default_2)
  puts "Args with defaults were: #{args}"
end

Then, from the command line:

> rake my_task[1,false]
Args were: {:arg1=>"1", :arg2=>"false"} of class Rake::TaskArguments
arg1 was: '1' of class String
arg2 was: 'false' of class String

> rake "my_task[1, 2]"
Args were: {:arg1=>"1", :arg2=>"2"}

> rake invoke_my_task
Args were: {:arg1=>"1", :arg2=>"2"}

> rake invoke_my_task_2
Args were: {:arg1=>3, :arg2=>4}

> rake with_prerequisite[5,6]
Args were: {:arg1=>"5", :arg2=>"6"}

> rake with_defaults
Args with defaults were: {:arg1=>:default_1, :arg2=>:default_2}

> rake with_defaults['x','y']
Args with defaults were: {:arg1=>"x", :arg2=>"y"}

As demonstrated in the second example, if you want to use spaces, the quotes around the target name are necessary to keep the shell from splitting up the arguments at the space.

Looking at the code in rake.rb, it appears that rake does not parse task strings to extract arguments for prerequisites, so you can't do task :t1 => "dep[1,2]". The only way to specify different arguments for a prerequisite would be to invoke it explicitly within the dependent task action, as in :invoke_my_task and :invoke_my_task_2.

Note that some shells (like zsh) require you to escape the brackets: rake my_task\['arg1'\]

You might want to look at csounds, also. It has several API's, including Python. It might be able to interact with an A-D interface and gather sound samples.

Anyway, thanks, I found this code snippet useful for quick debugging in IE. I have made some quick tweaks to fix a problem that stopped it working for me, also to scroll down automatically and use fixed positioning so it will appear in the viewport. Here's my version in case anyone finds it useful:

myLog = function() {

    var _div = null;

    this.toJson = function(obj) {

        if (typeof window.uneval == 'function') { return uneval(obj); }
        if (typeof obj == 'object') {
            if (!obj) { return 'null'; }
            var list = [];
            if (obj instanceof Array) {
                    for (var i=0;i < obj.length;i++) { list.push(this.toJson(obj[i])); }
                    return '[' + list.join(',') + ']';
            } else {
                    for (var prop in obj) { list.push('"' + prop + '":' + this.toJson(obj[prop])); }
                    return '{' + list.join(',') + '}';
            }
        } else if (typeof obj == 'string') {
            return '"' + obj.replace(/(["'])/g, '\\$1') + '"';
        } else {
            return new String(obj);
        }

    };

    this.createDiv = function() {

        myLog._div = document.body.appendChild(document.createElement('div'));

        var props = {
            position:'fixed', top:'10px', right:'10px', background:'#333', border:'5px solid #333', 
            color: 'white', width: '400px', height: '300px', overflow: 'auto', fontFamily: 'courier new',
            fontSize: '11px', whiteSpace: 'nowrap'
        }

        for (var key in props) { myLog._div.style[key] = props[key]; }

    };


    if (!myLog._div) { this.createDiv(); }

    var logEntry = document.createElement('span');

    for (var i=0; i < arguments.length; i++) {
        logEntry.innerHTML += this.toJson(arguments[i]) + '<br />';
    }

    logEntry.innerHTML += '<br />';

    myLog._div.appendChild(logEntry);

    // Scroll automatically to the bottom
    myLog._div.scrollTop = myLog._div.scrollHeight;

}

I don't have enough reputation to comment on any answer. In one of the comments, someone has asked how to ignore the hidden folders in the list. Below is how you can do this.

dir /b /AD-H

You need to have your DBA modify the init.ora file, adding the directory you want to access to the 'utl_file_dir' parameter. Your database instance will then need to be stopped and restarted because init.ora is only read when the database is brought up.

You can view (but not change) this parameter by running the following query:

SELECT *
  FROM V$PARAMETER
  WHERE NAME = 'utl_file_dir'

Share and enjoy.

Actually you can fix it with following steps -

1. Do cls.__dict__
2. This will give you dictionary format output which will contain {'isFilled':True} or {'isFilled':False} depending upon what you have set.
3. Delete this entry - del cls.__dict__['isFilled']
4. You will be able to call the method now.

In this case, we delete the entry which overrides the method as mentioned by BrenBarn.

That functionality is already built into Notepad++. From the "Edit" menu, select "EOL Conversion" -> "UNIX/OSX Format".

screenshot of the option for even quicker finding (or different language versions)

You can also set the default EOL in notepad++ via "Settings" -> "Preferences" -> "New Document/Default Directory" then select "Unix/OSX" under the Format box.

$domain = parse_url($url, PHP_URL_HOST);
echo implode('.', array_slice(explode('.', $domain), -2, 2))

Old way:

SELECT DATE_COLUMN + 1 is adding a day
SELECT DATE_COLUMN + N /24 to add hour(s) - N being number of hours
SELECT DATE_COLUMN + N /1440 to add minute(s) - N being number of minutes
SELECT DATE_COLUMN + N /86400 to add second(s) - N being number of seconds

Using INTERVAL:

SELECT DATE_COLUMN + INTERVAL 'N' HOUR or MINUTE or SECOND - N being a number of hours or minutes or seconds.

Try this in your batch file:

@echo off
start /d "C:\Program Files\Internet Explorer" IEXPLORE.EXE www.google.com
start /d "C:\Program Files\Internet Explorer" IEXPLORE.EXE www.yahoo.com

The package @angular/router has the Resolve property for routes. So you can easily resolve data before rendering a route view.

See: https://angular.io/docs/ts/latest/api/router/index/Resolve-interface.html

Example from docs as of today, August 28, 2017:

class Backend {
  fetchTeam(id: string) {
    return 'someTeam';
  }
}

@Injectable()
class TeamResolver implements Resolve<Team> {
  constructor(private backend: Backend) {}

  resolve(
    route: ActivatedRouteSnapshot,
    state: RouterStateSnapshot): Observable<any>|Promise<any>|any {
    return this.backend.fetchTeam(route.params.id);
  }
}

@NgModule({
  imports: [
    RouterModule.forRoot([
      {
        path: 'team/:id',
        component: TeamCmp,
        resolve: {
          team: TeamResolver
        }
      }
    ])
  ],
  providers: [TeamResolver]
})
class AppModule {}

Now your route will not be activated until the data has been resolved and returned.

Accessing Resolved Data In Your Component

To access the resolved data from within your component at runtime, there are two methods. So depending on your needs, you can use either:

1. route.snapshot.paramMap which returns a string, or the
2. route.paramMap which returns an Observable you can .subscribe() to.

Example:

  // the no-observable method
  this.dataYouResolved= this.route.snapshot.paramMap.get('id');
  // console.debug(this.licenseNumber);

  // or the observable method
  this.route.paramMap
     .subscribe((params: ParamMap) => {
        // console.log(params);
        this.dataYouResolved= params.get('id');
        return params.get('dataYouResolved');
        // return null
     });
  console.debug(this.dataYouResolved);

I hope that helps.

Static libraries are archives that contain the object code for the library, when linked into an application that code is compiled into the executable. Shared libraries are different in that they aren't compiled into the executable. Instead the dynamic linker searches some directories looking for the library(s) it needs, then loads that into memory. More then one executable can use the same shared library at the same time, thus reducing memory usage and executable size. However, there are then more files to distribute with the executable. You need to make sure that the library is installed onto the uses system somewhere where the linker can find it, static linking eliminates this problem but results in a larger executable file.

Here is another CSS solution. its take less line of code.

Then follow the procedure on GitHub.

All you have to do is open Anaconda Prompt and type

pip install package-name

It will automatically install to the anaconda environment without having to use

conda install package-name

Since some of the conda packages may lack support overtime it is required to install using pip and this is one way to do it

If you have pip installed in anaconda you can run the following in jupyter notebook or in your python shell that is linked to anaconda

pip.main(['install', 'package-name'])

Check your version of pip with pip.__version__. If it is version 10.x.x or above, then install your python package with this line of code

subprocess.check_call([sys.executable, '-m', 'pip', 'install', '--upgrade', 'package-name'])

In your jupyter notebook, you can install python packages through pip in a cell this way;

!pip install package-name

or you could use your python version associated with anaconda

!python3.6 -m pip install package-name

For me, align="center" was enough to center FOO vertically:

<v-row align="center">
  <v-col>FOO</v-col>
</row>

Split it by space and take first part like below. Hope this will help you.

var d = '12/12/1955 12:00:00 AM';
d = d.split(' ')[0];
console.log(d);

• async:false = Code paused. (Other code waiting for this to finish.)
• async:true = Code continued. (Nothing gets paused. Other code is not waiting.)

As simple as this.

It is possible to use patterns in a .gitignore file. See the gitignore man page. The pattern */target/* should ignore any directory named target and anything under it. Or you may try */target/** to ignore everything under target.

Try:

var Wrapper = React.createClass({
  render: function() {
    return (
      <div className="wrapper">
        before
          {this.props.children}
        after
      </div>
    );
  }
});

from jquery api

Added to jQuery in version 1.4, the .delay() method allows us to delay the execution of functions that follow it in the queue. It can be used with the standard effects queue or with a custom queue. Only subsequent events in a queue are delayed; for example this will not delay the no-arguments forms of .show() or .hide() which do not use the effects queue.

You can pass it in as part of the LinearLayout.LayoutParams constructor:

LinearLayout.LayoutParams param = new LinearLayout.LayoutParams(
    LayoutParams.MATCH_PARENT,
    LayoutParams.MATCH_PARENT,
    1.0f
);
YOUR_VIEW.setLayoutParams(param);

The last parameter is the weight.

One issue could be that if either make, model, or [serial number] were null, values would never get returned. Because string concatenations with null values always result in null, and not in () with null will always return nothing. The remedy for this is to use an operator such as IsNull(make, '') + IsNull(Model, ''), etc.

For the simple answer, you can use Link component from react-router, instead of button. There is ways to change the route in JS, but seems you don't need that here.

<span className="input-group-btn">
  <Link to="/login" />Click to login</Link>
</span>

To do it programmatically in 1.0.x, you do like this, inside your clickHandler function:

this.history.pushState(null, 'login');

Taken from upgrade doc here

You should have this.history placed on your route handler component by react-router. If it child component beneath that mentioned in routes definition, you may need pass that down further

"tail" is command to display the last part of a file, using proper available switches helps us to get more specific output. the most used switch for me is -n and -f

SYNOPSIS

tail [-F | -f | -r] [-q] [-b number | -c number | -n number] [file ...]

Here

-n number : The location is number lines.

-f : The -f option causes tail to not stop when end of file is reached, but rather to wait for additional data to be appended to the input. The -f option is ignored if the standard input is a pipe, but not if it is a FIFO.

Retrieve last 100 lines logs

To get last static 100 lines  
     tail -n 100 <file path>

To get real time last 100 lines
     tail -f -n 100 <file path>

There's a huge difference. As has been mentioned, <%@ include is a static include, <jsp:include is a dynamic include. Think of it as a difference between a macro and a function call (if you are familiar with those terms). Another way of putting it, a static include is exactly the same thing as copy-pasting the exact content of the included file (the "code") at the location of the <%@ include statement (which is exactly what the JSP compiler will do.

A dynamic include will make a request (using the request dispatcher) that will execute the indicated page and then include the output from the page in the output of the calling page, in place of the <jsp:include statement.

The big difference here is that with a dynamic include, the included page will execute in it's own pageContext. And since it's a request, you can send parameters to the page the same way you can send parameters along with any other request. A static include, on the other hand, is just a piece of code that will execute inside the context of the calling page. If you statically include the same file more than once, the code in that file will exist in multiple locations on the calling page so something like

<%
int i = 0;
%>

would generate a compiler error (since the same variable can't be declared more than once).

Generally you should also override hashCode() each time you override equals(), even if just for the performance boost. HashCode() decides which 'bucket' your object gets sorted into when doing a comparison, so any two objects which equal() evaluates to true should return the same hashCode value(). I cannot remember the default behavior of hashCode() (if it returns 0 then your code should work but slowly, but if it returns the address then your code will fail). I do remember a bunch of times when my code failed because I forgot to override hashCode() though. :)

From Tomcat documentation, For blocking I/O (BIO), the default value of maxConnections is the value of maxThreads unless Executor (thread pool) is used in which case, the value of 'maxThreads' from Executor will be used instead. For Non-blocking IO, it doesn't seem to be dependent on maxThreads.

Try calling read_csv with encoding='latin1', encoding='iso-8859-1' or encoding='cp1252' (these are some of the various encodings found on Windows).

Transferring files with Putty (pscp/plink.exe)

The default putty installation provides multiple ways to transfer files. Most likely putty is on your default path, so you can directly call putty from the command prompt. If it doesnt, you may have to change your environmental variables. See instructions here: https://it.cornell.edu/managed-servers/transfer-files-using-putt

Steps

1. Open command prompt by typing cmd

2. To transfer folders from your Windows computer to another Windows computer use (notice the -r flag, which indicates that the files will be transferred recursively, no need to zip them up): pscp -r -i C:/Users/username/.ssh/id_rsa.ppk "C:/Program Files (x86)/Terminal PC" [email protected]:/"C:/Program Files (x86)/"

3. To transfer files from your Windows computer to another Windows computer use: pscp -i C:/Users/username/.ssh/id_rsa.ppk "C:/Program Files (x86)/Terminal PC" [email protected]:/"C:/Program Files (x86)/"

4. Sometimes, you may only have plink installed. plink can potentially be used to transfer files, but its best restricted to simple text files. It may have unknown behavior with binary files (https://superuser.com/questions/1289455/create-text-file-on-remote-machine-using-plink-putty-with-contents-of-windows-lo): plink -i C:/Users/username/.ssh/id_rsa.ppk user@host <localfile "cat >hostfile"

5. To transfer files from a linux server to a Windows computer to a Linux computer use pscp -r -i C:/Users/username/.ssh/id_rsa.ppk "C:/Program Files (x86)/Terminal PC" [email protected]:/home/username

For all these to work, you need to have the proper public/private key. To generate that for putty see: https://superuser.com/a/1285789/658319

readline is specifically designed to work with terminal (that is process.stdin.isTTY === true). There are a lot of modules which provide split functionality for generic streams, like split. It makes things super-easy:

process.stdin.pipe(require('split')()).on('data', processLine)

function processLine (line) {
  console.log(line + '!')
}

My experience is that if you want to do like in this article, like stated above.

Your markup file (aspx/ascx) has to include the CodeBehind="MyPage.aspx.cs" attribute or else it won´t work. I blogged about it here.

Use this

if let navVCsCount = navigationController?.viewControllers.count {
    navigationController?.viewControllers.removeSubrange(Range(2..<navVCsCount - 1))
}

It will take care of ViewControllers of navigationController. viewControllers and also a navigationItems stacked in navigationBar.

Note: Be sure to call it at least after viewDidAppear

In String Context:
compareTo: Compares two strings lexicographically.
equals: Compares this string to the specified object.

compareTo compares two strings by their characters (at same index) and returns an integer (positive or negative) accordingly.

String s1 = "ab";
String s2 = "ab";
String s3 = "qb";
s1.compareTo(s2); // is 0
s1.compareTo(s3); // is -16
s3.compareTo(s1); // is 16

Expect is built for this and can handle the input/output plus timeouts etc. Note that if you're not a TCL fan, there are Expect modules for Perl/Python/Java.

EDIT: The above page suggests that the Wikipedia Expect entry is a useful resource :-)

Docker + NGINX

In my situation, the problem was nginx docker container disk space. I had 10GB of logs and when I reduce this amount it works.

Step by step (for rookies/newbies)

1. Enter in your container: docker exec -it <container_id> bash

2. Go to your logs, for example: cd /var/log/nginx.

3. [optional] Show file size: ls -lh for individual file size or du -h for folder size.

4. Empty file(s) with > file_name.

5. It works!.

For advanced developers/sysadmins

Empty your nginx log with > file_name or similar.

Hope it helps

Try:

title = re.search('<title>(.*)</title>', html, re.IGNORECASE).group(1)

With pandas it can be done as:

If lakes is your DataFrame:

area_dict = lakes.to_dict('records')

Try this

SELECT 
    DateAppr,
    TimeAppr,
    TAT,
    LaserLTR,
    Permit,
    LtrPrinter,
    JobName,
    JobNumber,
    JobDesc,
    ActQty,
    (ActQty-LtrPrinted) AS L,
    (ActQty-QtyInserted) AS M,
    ((ActQty-LtrPrinted)-(ActQty-QtyInserted)) AS N
FROM 
    [test].[dbo].[MM]
WHERE 
    DateDropped = 0
    AND (
    (ISNULL(@JobsOnHold, 0) = 1 AND DateAppr >= 0) 
    OR 
    (ISNULL(@JobsOnHold, 0) != 1 AND DateAppr != 0)
    )

You can read more about conditional WHERE here.

You could create a Automator workflow with a single step - "Run Shell Script"

Then File > Save As, and change the File Format to "Application". When you open the application, it will run the Shell Script step, executing the command, exiting after it completes.

The benefit to this is it's really simple to do, and you can very easily get user input (say, selecting a bunch of files), then pass it to the input of the shell script (either to stdin, or as arguments).

(Automator is in your /Applications folder!)

If you came here to find out about how to check WordPress version programmatically, then you can do it with the following code.

// Get the WP Version global.
global $wp_version;

// Now use $wp_version which will return a string value.
echo '<pre>' . var_dump( $wp_version ) . '</pre>';
// Output: string '4.6.1' (length=5)

Cheers!

So that you don't mess up other permissions already on the file, use the flag +, such as via

sudo chmod -R o+rw /var/www

 SELECT * FROM ALL_source WHERE UPPER(text) LIKE '%BLAH%'

EDIT Adding additional info:

 SELECT * FROM DBA_source WHERE UPPER(text) LIKE '%BLAH%'

The difference is dba_source will have the text of all stored objects. All_source will have the text of all stored objects accessible by the user performing the query. Oracle Database Reference 11g Release 2 (11.2)

Another difference is that you may not have access to dba_source.

revalidate() just request to layout the container, when you experienced simply call revalidate() works, it could be caused by the updating of child components bounds triggers the repaint() when their bounds are changed during the re-layout. In the case you mentioned, only component removed and no component bounds are changed, this case no repaint() is "accidentally" triggered.

I'll try and explain it as simple as possible. So there is no guarantee of the accuracy of the actual terms.

Session is where to initiate the connectivity to AWS services. E.g. following is default session that uses the default credential profile(e.g. ~/.aws/credentials, or assume your EC2 using IAM instance profile )

sqs = boto3.client('sqs')
s3 = boto3.resource('s3')

Because default session is limit to the profile or instance profile used, sometimes you need to use the custom session to override the default session configuration (e.g. region_name, endpoint_url, etc. ) e.g.

# custom resource session must use boto3.Session to do the override
my_west_session = boto3.Session(region_name = 'us-west-2')
my_east_session = boto3.Session(region_name = 'us-east-1')
backup_s3 = my_west_session.resource('s3')
video_s3 = my_east_session.resource('s3')

# you have two choices of create custom client session. 
backup_s3c = my_west_session.client('s3')
video_s3c = boto3.client("s3", region_name = 'us-east-1')

Resource : This is the high-level service class recommended to be used. This allows you to tied particular AWS resources and passes it along, so you just use this abstraction than worry which target services are pointed to. As you notice from the session part, if you have a custom session, you just pass this abstract object than worrying about all custom regions,etc to pass along. Following is a complicated example E.g.

import boto3 
my_west_session = boto3.Session(region_name = 'us-west-2')
my_east_session = boto3.Session(region_name = 'us-east-1')
backup_s3 = my_west_session.resource("s3")
video_s3 = my_east_session.resource("s3")
backup_bucket = backup_s3.Bucket('backupbucket') 
video_bucket = video_s3.Bucket('videobucket')

# just pass the instantiated bucket object
def list_bucket_contents(bucket):
   for object in bucket.objects.all():
      print(object.key)

list_bucket_contents(backup_bucket)
list_bucket_contents(video_bucket)

Client is a low level class object. For each client call, you need to explicitly specify the targeting resources, the designated service target name must be pass long. You will lose the abstraction ability.

For example, if you only deal with the default session, this looks similar to boto3.resource.

import boto3 
s3 = boto3.client('s3')

def list_bucket_contents(bucket_name):
   for object in s3.list_objects_v2(Bucket=bucket_name) :
      print(object.key)

list_bucket_contents('Mybucket') 

However, if you want to list objects from a bucket in different regions, you need to specify the explicit bucket parameter required for the client.

import boto3 
backup_s3 = my_west_session.client('s3',region_name = 'us-west-2')
video_s3 = my_east_session.client('s3',region_name = 'us-east-1')

# you must pass boto3.Session.client and the bucket name 
def list_bucket_contents(s3session, bucket_name):
   response = s3session.list_objects_v2(Bucket=bucket_name)
   if 'Contents' in response:
     for obj in response['Contents']:
        print(obj['key'])

list_bucket_contents(backup_s3, 'backupbucket')
list_bucket_contents(video_s3 , 'videobucket') 

I got this error when using Delphi with the LiteDAC components. Turned out it only happened while running my app from the Delphi IDE if the Connected property was set True for the SQLite connection component (in this case TLiteConnection).

You can do like as.....

$originalDate = "1585876500";

echo $newDate = date("Y-m-d h:i:sa", date($originalDate));

This might not be very applicable to others, but my problem was that the changes I made was NOT saved yet! Press CMD + S and save your work before building on top of it.

To apply different classes when different expressions evaluate to true:

<div ng-class="{class1 : expression1, class2 : expression2}">
    Hello World!
</div>

To apply multiple classes when an expression holds true:

<!-- notice expression1 used twice -->
<div ng-class="{class1 : expression1, class2 : expression1}">
    Hello World!
</div>

or quite simply:

<div ng-class="{'class1 class2' : expression1}">
    Hello World!
</div>

Notice the single quotes surrounding css classes.

I dont know if its too late, but i thought it would help someone else.

I wanted the same badly...found it eventually.

Send the email to a real SMTP server. If you don't want to set up your own then you can find companies that will run one for you, such as Google themselves.

Here is code that works:

import java.util.Arrays;
import java.util.Collections;

public class Test
{
    public static void main(String[] args)
    {
        orderedGuests1(new String[] { "c", "a", "b" });
        orderedGuests2(new String[] { "c", "a", "b" });
    }

    public static void orderedGuests1(String[] hotel)
    {
        Arrays.sort(hotel);
        System.out.println(Arrays.toString(hotel));
    }

    public static void orderedGuests2(String[] hotel)
    {
        Collections.sort(Arrays.asList(hotel));
        System.out.println(Arrays.toString(hotel));
    }

}

Select Top 1 can easily resolve it without the need of any sequence/order.

    Select Top 1 @ID = ID, @Num = RangeFrom, @RangeTo = RangeTo  From @RangeTable
    Where ID > @ID
    While @Num <= @RangeTo

Options must bind an array as follows. It can change based on the requirement.

types= [
        {
            "id": "1",
            "value": "Type 1"
        },
        {
             "id": "2",
             "value": "Type 2"
        },
        {
              "id": "3",
              "value": "Type 3"
        }] 

Adding images to the drawable folder is pretty simple. Just follow these steps:

1. Download the required image and save it on desktop.
2. Now, go to Android Studio and right click on drawable inside res.
3. On right clicking you will see 'Show in Explorer' or 'Reveal in Finder'.
4. Click on 'Show in Explorer' or 'Reveal in Finder' and then drag or simply copy your downloaded image into drawable folder.

Your image will be saved inside drawable and you can use it.

In my case my Build Tools version in my build.gradle for the app module was outdated on an old project. Updating it fixed the issue:

android {
    ...
    buildToolsVersion "19.0.1"
    ...

Updated to the latest build tools version (25.0.1) and sync'd the project and all was well again.

I try to write working code example, I test it and everything works.

Hare is code:

HTML:

<input type="file" class="attachment_input" name="file" onchange="checkFileSize(this, @Model.MaxSize.ToString(),@Html.Raw(Json.Encode(Model.FileExtensionsList)))" />

Javascript:

 //function for check attachment size and extention match
function checkFileSize(element, maxSize, extentionsArray) {
    var val = $(element).val(); //get file value

    var ext = val.substring(val.lastIndexOf('.') + 1).toLowerCase(); // get file extention 
    if ($.inArray(ext, extentionsArray) == -1) {
        alert('false extension!');
    }

    var fileSize = ($(element)[0].files[0].size / 1024 / 1024); //size in MB
    if (fileSize > maxSize) {
        alert("Large file");// if Maxsize from Model > real file size alert this
    }
}

I don't think there are any machine code decompilers that produce Pascal code. Most "Delphi decompilers" parse form and RTTI data, but do not actually decompile the machine code. I can only recommend using something like DeDe (or similar software) to extract symbol information in combination with a C decompiler, then translate the decompiled C code to Delphi (there are many source code converters out there).

Initializing the Canvas like below works for TypeScript/Angular solutions.

const canvas = <HTMLCanvasElement> document.getElementById("htmlElemId"); 

const context = canvas.getContext("2d"); 

Using WHERE DATE(datetime) = '2009-10-20' has performance issues. As stated here:

• it will calculate DATE() for all rows, including those that don't match.
• it will make it impossible to use an index for the query.

Use BETWEEN or >, <, = operators which allow to use an index:

SELECT * FROM data 
WHERE datetime BETWEEN '2009-10-20 00:00:00' AND '2009-10-20 23:59:59'

Update: the impact on using LIKE instead of operators in an indexed column is high. These are some test results on a table with 1,176,000 rows:

• using datetime LIKE '2009-10-20%' => 2931ms
• using datetime >= '2009-10-20 00:00:00' AND datetime <= '2009-10-20 23:59:59' => 168ms

When doing a second call over the same query the difference is even higher: 2984ms vs 7ms (yes, just 7 milliseconds!). I found this while rewriting some old code on a project using Hibernate.

A union query can only have one master ORDER BY clause, IIRC. To get this, in each query making up the greater UNION query, add a field that will be the one field you sort by for the UNION's ORDER BY.

For instance, you might have something like

SELECT field1, field2, '1' AS union_sort
UNION SELECT field1, field2, '2' AS union_sort
UNION SELECT field1, field2, '3' AS union_sort
ORDER BY union_sort

That union_sort field can be anything you may want to sort by. In this example, it just happens to put results from the first table first, second table second, etc.

Empty returns true if the var is not set. But isset returns true even if the var is not empty.

I preferred search last blank cell:

Il you want last empty cell of column you can do that

Dim sh as Worksheet, r as range
set sh = ActiveWorksheet 'if you want an other it's possible

'find a value 
'Columns("A:D") 'to check on multiple columns 
Set r = sh.Columns("A").Find(What:="*", SearchOrder:=xlByRows, SearchDirection:=xlPrevious)
'no value return first row
If r Is Nothing Then Set r = sh.Cells(1, "A") Else Set r = sh1.Cells(r.Row + 1, "A")

If this is to insert new row, find on multiple columns is a good choice because first column can contains less rows than next columns

While Loop is an obsolete structure, I would recommend you to replace "While loop" to "Do While..loop", and you will able to use Exit clause.

check = 0 

Do while not rs.EOF 
   if rs("reg_code") = rcode then 
      check = 1 
      Response.Write ("Found") 
      Exit do
   else 
      rs.MoveNext 
    end if 
Loop 

if check = 0 then 
   Response.Write "Not Found" 
end if}

Just in case anybody want to find how in oracle and came here (like me), the syntax is

select length(FIELD) from TABLE

just in case ;)

I've had this problem. See The Python "Connection Reset By Peer" Problem.

You have (most likely) run afoul of small timing issues based on the Python Global Interpreter Lock.

You can (sometimes) correct this with a time.sleep(0.01) placed strategically.

"Where?" you ask. Beats me. The idea is to provide some better thread concurrency in and around the client requests. Try putting it just before you make the request so that the GIL is reset and the Python interpreter can clear out any pending threads.

If __file__ is available:

# -- script1.py --
import os
file_path = os.path.abspath(__file__)
print(os.path.dirname(file_path))

For those we want to be able to run the command from the interpreter or get the path of the place you're running the script from:

# -- script2.py --
import os
print(os.path.abspath(''))

This works from the interpreter. But when run in a script (or imported) it gives the path of the place where you ran the script from, not the path of directory containing the script with the print.

Example:

If your directory structure is

test_dir (in the home dir)
+-- main.py
+-- test_subdir
    +-- script1.py
    +-- script2.py

with

# -- main.py --
import script1.py
import script2.py

The output is:

~/test_dir/test_subdir
~/test_dir

This is the simple example to use both of them:

import {
  Directive, HostListener, HostBinding
}
from '@angular/core';

@Directive({
  selector: '[Highlight]'
})
export class HighlightDirective {
  @HostListener('mouseenter') mouseover() {
    this.backgroundColor = 'green';
  };

  @HostListener('mouseleave') mouseleave() {
    this.backgroundColor = 'white';
  }

  @HostBinding('style.backgroundColor') get setColor() {
     return this.backgroundColor;
  };

  private backgroundColor = 'white';
  constructor() {}

}

Introduction:

1. HostListener can bind an event to the element.

2. HostBinding can bind a style to the element.

3. this is directive, so we can use it for

   Some Text

4. So according to the debug, we can find that this div has been binded style = "background-color:white"

   Some Text

5. we also can find that EventListener of this div has two event: mouseenter and mouseleave. So when we move the mouse into the div, the colour will become green, mouse leave, the colour will become white.

getJSONArray(attrname) will get you an array from the object of that given attribute name in your case what is happening is that for

{"abridged_cast":["name": blah...]}
^ its trying to search for a value "characters"

but you need to get into the array and then do a search for "characters"

try this

String json="{'abridged_cast':[{'name':'JeffBridges','id':'162655890','characters':['JackPrescott']},{'name':'CharlesGrodin','id':'162662571','characters':['FredWilson']},{'name':'JessicaLange','id':'162653068','characters':['Dwan']},{'name':'JohnRandolph','id':'162691889','characters':['Capt.Ross']},{'name':'ReneAuberjonois','id':'162718328','characters':['Bagley']}]}";

    JSONObject jsonResponse;
    try {
        ArrayList<String> temp = new ArrayList<String>();
        jsonResponse = new JSONObject(json);
        JSONArray movies = jsonResponse.getJSONArray("abridged_cast");
        for(int i=0;i<movies.length();i++){
            JSONObject movie = movies.getJSONObject(i);
            JSONArray characters = movie.getJSONArray("characters");
            for(int j=0;j<characters.length();j++){
                temp.add(characters.getString(j));
            }
        }
        Toast.makeText(this, "Json: "+temp, Toast.LENGTH_LONG).show();
    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

checked it :)

I know that this isn't what you asked for but LINQPad is a really great tool to teach yourself LINQ (and it's free :o).

When time isn't critical, I have been using it for the last week or so instead or a query window in SQL Server and my LINQ skills are getting better and better.

It's also a nice little code snippet tool. Its only downside is that the free version doesn't have IntelliSense.

The problem with this is that when the SQL engine goes to evaluate the expression, it checks the FROM portion to pull the proper tables, and then the WHERE portion to provide some base criteria, so it cannot properly evaluate a dynamic condition on which column to check against.

You can use a WHERE clause when you're checking the WHERE criteria in the predicate, such as

WHERE account_location = CASE @locationType
                              WHEN 'business' THEN 45
                              WHEN 'area' THEN 52
                         END

so in your particular case, you're going to need put the query into a stored procedure or create three separate queries.

One gotcha I have found is where two objects contain references to each other (one example being a parent/child relationship with a convenience method on the parent to get all children).
These sorts of things are fairly common when doing Hibernate mappings for example.

If you include both ends of the relationship in your hashCode or equals tests it's possible to get into a recursive loop which ends in a StackOverflowException.
The simplest solution is to not include the getChildren collection in the methods.

To answer a little more conceptually:

SelectedValuePath defines which property (by its name) of the objects bound to the ListBox's ItemsSource will be used as the item's SelectedValue.

For example, if your ListBox is bound to a collection of Person objects, each of which has Name, Age, and Gender properties, SelectedValuePath=Name will cause the value of the selected Person's Name property to be returned in SelectedValue.

Note that if you override the ListBox's ControlTemplate (or apply a Style) that specifies what property should display, SelectedValuePath cannot be used.

SelectedItem, meanwhile, returns the entire Person object currently selected.

(Here's a further example from MSDN, using TreeView)

Update: As @Joe pointed out, the DisplayMemberPath property is unrelated to the Selected* properties. Its proper description follows:

Note that these values are distinct from DisplayMemberPath (which is defined on ItemsControl, not Selector), but that property has similar behavior to SelectedValuePath: in the absence of a style/template, it identifies which property of the object bound to item should be used as its string representation.

I would like to add to some of the other answers here, if you don't need the first item but say the second number for example you can use rownumber in a subquery and base your result set off of that.

SELECT * FROM
(
    SELECT
        ROW_NUM() OVER (PARTITION BY Id ORDER BY record_date, other_cols) as rownum,
        *
    FROM products P
) INNER
WHERE rownum = 2

This also allows you to order off multiple columns in the subquery which may help if two record_dates have identical values. You can also partition off of multiple columns if needed by delimiting them with a comma

From the Python documentation:

This object is commonly used by slicing (see Slicings). It supports no special operations. There is exactly one ellipsis object, named Ellipsis (a built-in name). type(Ellipsis)() produces the Ellipsis singleton.

It is written as Ellipsis or ....

The dropdown width itself cannot be set. It's width depend on the option-values. See also here ( jsfiddle.net/LgS3C/ )

How the select box looks like is also depending on your browser.

You can build your own control or use Select2 https://select2.org

The move instruction copies a value from one register to another. The li instruction loads a specific numeric value into that register.

For the specific case of zero, you can use either the constant zero or the zero register to get that:

move $s0, $zero
li   $s0, 0

There's no register that generates a value other than zero, though, so you'd have to use li if you wanted some other number, like:

li $s0, 12345678

Adding to @marbel's answer (which is a great suggestion!), here's the script that worked for me on Mac OS X El Captain's Terminal, for batch conversion (since that's what the OP asked). I thought it would be trivial to do a for loop but it wasn't! (had to change the extension by string manipulation and it looks like Mac's bash is a bit different also)

for x in $(ls *.xlsx); do x1=${x%".xlsx"}; in2csv $x > $x1.csv; echo "$x1.csv done."; done

Note:

1. ${x%”.xlsx”} is bash string manipulation which clips .xlsx from the end of the string.
2. in2csv creates separate csv files (doesn’t overwrite the xlsx's).
3. The above won't work if the filenames have white spaces in them. Good to convert white spaces to underscores or something, before running the script.

If your compiler supports C++11 standard, there is a constructor inheritance using using (pun intended). For more see Wikipedia C++11 article. You write:

class A
{
    public: 
        explicit A(int x) {}
};

class B: public A
{
     using A::A;
};

This is all or nothing - you cannot inherit only some constructors, if you write this, you inherit all of them. To inherit only selected ones you need to write the individual constructors manually and call the base constructor as needed from them.

Historically constructors could not be inherited in the C++03 standard. You needed to inherit them manually one by one by calling base implementation on your own.

os.rename(old, new)

This is found in the Python docs: http://docs.python.org/library/os.html

For a popup javascript is required. Put this in your header:

<script>
function myFunction()
{
alert("I am an alert box!"); // this is the message in ""
}
</script>

And this in your body:

<input type="button" onclick="myFunction()" value="Show alert box">

When the button is pressed a box pops up with the message set in the header.

This can be put in any html or php file without the php tags.

-----EDIT-----

To display it using php try this:

<?php echo '<script>myfunction()</script>'; ?>

It may not be 100% correct but the principle is the same.

To display different messages you can either create lots of functions or you can pass a variable in to the function when you call it.

The antonym of Hard-Coding is Soft-Coding. For a better understanding of Hard Coding, I will introduce both terms.

• Hard-coding: feature is coded to the system not allowing for configuration;
• Parametric: feature is configurable via table driven, or properties files with limited parametric values ;
• Soft-coding: feature uses “engines” that derive results based on any number of parametric values (e.g. business rules in BRE); rules are coded but exist as parameters in system, written in script form

Examples:

// firstName has a hard-coded value of "hello world"
string firstName = "hello world";

// firstName has a non-hard-coded provided as input
Console.WriteLine("first name :");
string firstName = Console.ReadLine();

A hard-coded constant^[1]:

float areaOfCircle(int radius)
{
    float area = 0;
    area = 3.14*radius*radius;  //  3.14 is a hard-coded value
    return area;
}

Additionally, hard-coding and soft-coding could be considered to be anti-patterns^[2]. Thus, one should strive for balance between hard and soft-coding.

1. Hard Coding “Hard coding” is a well-known antipattern against which most web development books warns us right in the preface. Hard coding is the unfortunate practice in which we store configuration or input data, such as a file path or a remote host name, in the source code rather than obtaining it from a configuration file, a database, a user input, or another external source.
   
   The main problem with hard code is that it only works properly in a certain environment, and at any time the conditions change, we need to modify the source code, usually in multiple separate places.
   
   
2. Soft Coding
   If we try very hard to avoid the pitfall of hard coding, we can easily run into another antipattern called “soft coding”, which is its exact opposite.
   
   In soft coding, we put things that should be in the source code into external sources, for example we store business logic in the database. The most common reason why we do so, is the fear that business rules will change in the future, therefore we will need to rewrite the code.
   
   In extreme cases, a soft coded program can become so abstract and convoluted that it is almost impossible to comprehend it (especially for new team members), and extremely hard to maintain and debug.

Another easy way to handle this is to use the argument allowSetters=truein the annotation. This will allow the password to be deserialized into your dto but it will not serialize it into a response body that uses contains object.

example:

@JsonIgnoreProperties(allowSetters = true, value = {"bar"})
class Pojo{
    String foo;
    String bar;
}

Both foo and bar are populated in the object, but only foo is written into a response body.

Jaanna, the session parameters in Oracle SQL Developer are dependent on your client computer, while the NLS parameters on PL/SQL is from server.

For example the NLS_NUMERIC_CHARACTERS on client computer can be ',.' while it's '.,' on server.

So when you run script from PL/SQL and Oracle SQL Developer the decimal separator can be completely different for the same script, unless you alter session with your expected NLS_NUMERIC_CHARACTERS in the script.

One way to easily test your session parameter is to do:

select to_number(5/2) from dual;

Try adding a pair of class attributes, say 'even' and 'odd', to alternating list elements, e.g.

<ul>
    <li class="even"><a href="link">Link 1</a></li>
    <li class="odd"><a href="link">Link 2</a></li>
    <li class="even"><a href="link">Link 3</a></li>
    <li class="odd"><a href="link">Link 4</a></li>
    <li class="even"><a href="link">Link 5</a></li>
</ul>

In a <style> section of the HTML page, or in a linked stylesheet, you would define those same classes, specifying your desired background colours:

li.even { background-color: red; }
li.odd { background-color: blue; }

You might want to use a template library as your needs evolve to provide you with greater flexibility and to cut down on the typing. Why type all those list elements by hand?

Another way to do it in Java 7 or earlier would be to use Guava:

public static String[] names() {
    return FluentIterable.from(values()).transform(Enum::name).toArray(String.class);
}

You can do it entirely in JavaScript:

IE has (for a long time) standard API for clearing Basic Authentication cache:

document.execCommand("ClearAuthenticationCache")

Should return true when it works. Returns either false, undefined or blows up on other browsers.

New browsers (as of Dec 2012: Chrome, FireFox, Safari) have "magic" behavior. If they see a successful basic auth request with any bogus other username (let's say logout) they clear the credentials cache and possibly set it for that new bogus user name, which you need to make sure is not a valid user name for viewing content.

Basic example of that is:

var p = window.location.protocol + '//'
// current location must return 200 OK for this GET
window.location = window.location.href.replace(p, p + 'logout:password@')

An "asynchronous" way of doing the above is to do an AJAX call utilizing the logout username. Example:

(function(safeLocation){
    var outcome, u, m = "You should be logged out now.";
    // IE has a simple solution for it - API:
    try { outcome = document.execCommand("ClearAuthenticationCache") }catch(e){}
    // Other browsers need a larger solution - AJAX call with special user name - 'logout'.
    if (!outcome) {
        // Let's create an xmlhttp object
        outcome = (function(x){
            if (x) {
                // the reason we use "random" value for password is 
                // that browsers cache requests. changing
                // password effectively behaves like cache-busing.
                x.open("HEAD", safeLocation || location.href, true, "logout", (new Date()).getTime().toString())
                x.send("")
                // x.abort()
                return 1 // this is **speculative** "We are done." 
            } else {
                return
            }
        })(window.XMLHttpRequest ? new window.XMLHttpRequest() : ( window.ActiveXObject ? new ActiveXObject("Microsoft.XMLHTTP") : u ))
    }
    if (!outcome) {
        m = "Your browser is too old or too weird to support log out functionality. Close all windows and restart the browser."
    }
    alert(m)
    // return !!outcome
})(/*if present URI does not return 200 OK for GET, set some other 200 OK location here*/)

You can make it a bookmarklet too:

javascript:(function(c){var a,b="You should be logged out now.";try{a=document.execCommand("ClearAuthenticationCache")}catch(d){}a||((a=window.XMLHttpRequest?new window.XMLHttpRequest:window.ActiveXObject?new ActiveXObject("Microsoft.XMLHTTP"):void 0)?(a.open("HEAD",c||location.href,!0,"logout",(new Date).getTime().toString()),a.send(""),a=1):a=void 0);a||(b="Your browser is too old or too weird to support log out functionality. Close all windows and restart the browser.");alert(b)})(/*pass safeLocation here if you need*/);

I have worked on some servers where sort don't support '-u' option. there we have to use

sort xyz | uniq

My answer is similar to this one on ServerFault.com.

To Be Conservative

If you want to be more conservative than granting "all privileges", you might want to try something more like these.

GRANT SELECT, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA public TO some_user_;
GRANT EXECUTE ON ALL FUNCTIONS IN SCHEMA public TO some_user_;

The use of public there refers to the name of the default schema created for every new database/catalog. Replace with your own name if you created a schema.

Access to the Schema

To access a schema at all, for any action, the user must be granted "usage" rights. Before a user can select, insert, update, or delete, a user must first be granted "usage" to a schema.

You will not notice this requirement when first using Postgres. By default every database has a first schema named public. And every user by default has been automatically been granted "usage" rights to that particular schema. When adding additional schema, then you must explicitly grant usage rights.

GRANT USAGE ON SCHEMA some_schema_ TO some_user_ ;

Excerpt from the Postgres doc:

For schemas, allows access to objects contained in the specified schema (assuming that the objects' own privilege requirements are also met). Essentially this allows the grantee to "look up" objects within the schema. Without this permission, it is still possible to see the object names, e.g. by querying the system tables. Also, after revoking this permission, existing backends might have statements that have previously performed this lookup, so this is not a completely secure way to prevent object access.

For more discussion see the Question, What GRANT USAGE ON SCHEMA exactly do?. Pay special attention to the Answer by Postgres expert Craig Ringer.

Existing Objects Versus Future

These commands only affect existing objects. Tables and such you create in the future get default privileges until you re-execute those lines above. See the other answer by Erwin Brandstetter to change the defaults thereby affecting future objects.

You can also use python module file_read_backwards.

After installing it, via pip install file_read_backwards (v1.2.1), you can read the entire file backwards (line-wise) in a memory efficient manner via:

#!/usr/bin/env python2.7

from file_read_backwards import FileReadBackwards

with FileReadBackwards("/path/to/file", encoding="utf-8") as frb:
    for l in frb:
         print l

It supports "utf-8","latin-1", and "ascii" encodings.

Support is also available for python3. Further documentation can be found at http://file-read-backwards.readthedocs.io/en/latest/readme.html

Take a look at the section about filling in forms using webdriver in the selenium documentation and the javadoc for the Select class.

To select an option based on the label:

Select select = new Select(driver.findElement(By.xpath("//path_to_drop_down")));
select.deselectAll();
select.selectByVisibleText("Value1");

To get the first selected value:

WebElement option = select.getFirstSelectedOption()

The NoSuchMethodError javadoc says this:

Thrown if an application tries to call a specified method of a class (either static or instance), and that class no longer has a definition of that method.

Normally, this error is caught by the compiler; this error can only occur at run time if the definition of a class has incompatibly changed.

In your case, this Error is a strong indication that your webapp is using the wrong version of the JAR defining the org.objectweb.asm.* classes.

HashSet don't maintain the order of insertion item
LinkedHashSet maintain the order of insertion item

Example

Set<String> set = ...;// using new HashSet<>() OR new LinkedHashSet<>()
set.add("2");
set.add("1");
set.add("ab");
for(String value : set){
   System.out.println(value);
}  

HashSet output

1
ab
2

LinkedHashSet output

2
1
ab

Center x = x + 1/2 of width

Center y = y + 1/2 of height 

If you know the width and height already then you only need one set of coordinates.

Maybe it's not pythonic way, but you can do this

import ctypes

def incr(a):
    a += 1

x = ctypes.c_int(1) # create c-var
incr(ctypes.ctypes.byref(x)) # passing by ref

September 2020 - Programmatically Answer

You can do it with programmatically for Switch Widget and Material Design:

Switch yourSwitchButton = findViewById(R.id.switch_id);

yourSwitchButton.setChecked(true); // true is open, false is close.

yourSwitchButton.setOnCheckedChangeListener((compoundButton, b) -> {
        if (b){
          //open job.
        }  
        else  {
          //close job.
        }
    });

@canerkaseler

Why can't we do this.

Give the optional argument a default value. In that way, the caller of the function don't necessarily need to pass the value of the argument. The argument takes the default value. And easily that argument becomes optional for the client.

For e.g.

void foo(int a, int b = 0);

Here b is an optional argument.

This solved the problem for me on Ubuntu 12.04 after every suggestion here had failed.

RMStore is a lightweight iOS library for In-App Purchases. It wraps StoreKit API and provides you with handy blocks for asynchronous requests. Purchasing a product is as easy as calling a single method.

For the advanced users, this library also provides receipt verification, content downloads and transaction persistence.

In terms of bytecode, in saves a LOAD_ATTR and replaces a CALL_FUNCTION with a COMPARE_OP.

>>> dis.dis(indict)
  2           0 LOAD_GLOBAL              0 (name)
              3 LOAD_GLOBAL              1 (d)
              6 COMPARE_OP               6 (in)
              9 POP_TOP             


>>> dis.dis(haskey)
  2           0 LOAD_GLOBAL              0 (d)
              3 LOAD_ATTR                1 (haskey)
              6 LOAD_GLOBAL              2 (name)
              9 CALL_FUNCTION            1
             12 POP_TOP             

My feelings are that in is much more readable and is to be preferred in every case that I can think of.

In terms of performance, the timing reflects the opcode

$ python -mtimeit -s'd = dict((i, i) for i in range(10000))' "'foo' in d"
 10000000 loops, best of 3: 0.11 usec per loop

$ python -mtimeit -s'd = dict((i, i) for i in range(10000))' "d.has_key('foo')"
  1000000 loops, best of 3: 0.205 usec per loop

in is almost twice as fast.

My lightweight implementation of ParallelForEach async.

Features:

1. Throttling (max degree of parallelism).
2. Exception handling (aggregation exception will be thrown at completion).
3. Memory efficient (no need to store the list of tasks).

public static class AsyncEx
{
    public static async Task ParallelForEachAsync<T>(this IEnumerable<T> source, Func<T, Task> asyncAction, int maxDegreeOfParallelism = 10)
    {
        var semaphoreSlim = new SemaphoreSlim(maxDegreeOfParallelism);
        var tcs = new TaskCompletionSource<object>();
        var exceptions = new ConcurrentBag<Exception>();
        bool addingCompleted = false;

        foreach (T item in source)
        {
            await semaphoreSlim.WaitAsync();
            asyncAction(item).ContinueWith(t =>
            {
                semaphoreSlim.Release();

                if (t.Exception != null)
                {
                    exceptions.Add(t.Exception);
                }

                if (Volatile.Read(ref addingCompleted) && semaphoreSlim.CurrentCount == maxDegreeOfParallelism)
                {
                    tcs.TrySetResult(null);
                }
            });
        }

        Volatile.Write(ref addingCompleted, true);
        await tcs.Task;
        if (exceptions.Count > 0)
        {
            throw new AggregateException(exceptions);
        }
    }
}

Usage example:

await Enumerable.Range(1, 10000).ParallelForEachAsync(async (i) =>
{
    var data = await GetData(i);
}, maxDegreeOfParallelism: 100);

For future reference:

 yyyy => 4 digit year
 MM   => 2 digit month (you must type MM in ALL CAPS)
 dd   => 2 digit "day of the month"

 HH   => 2-digit "hour in day" (0 to 23)
 mm   => 2-digit minute (you must type mm in lowercase)
 ss   => 2-digit seconds
 SSS  => milliseconds

So "yyyy-MM-dd HH:mm:ss" returns "2018-01-05 09:49:32"

But "MMM dd, yyyy hh:mm a" returns "Jan 05, 2018 09:49 am"

The so-called examples at https://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html show only output. They do not tell you what formats to use!

You may be overcomplicating things, is there any reason you need the stringr package?

 df <- data.frame(Date = c("10/9/2009 0:00:00", "10/15/2009 0:00:00"))
 as.Date(df$Date, "%m/%d/%Y %H:%M:%S")

[1] "2009-10-09" "2009-10-15"

More generally and if you need the time component as well, use strptime:

strptime(df$Date, "%m/%d/%Y %H:%M:%S")

I'm guessing at what your actual data might look at from the partial results you give.

Already answered above but wanted to share.

Will not work in IE though. thanks for mentioning it @Mahmoud

got some reference Here. they also have Polyfill for above.

To add on nathan gonzalez answer, please note you need to assign the replaced object after calling replace function since it is not a mutator function:

myString = myString.replace('username1','');

The easiest way to do this is to let bash do it:

set -x

Or run it explicitly as bash -x myscript.

Are you also validating server-side? This is very important.

Using regular expressions for e-mail isn't considered best practice since it's almost impossible to properly encapsulate all of the standards surrounding email. If you do have to use regular expressions I'll usually go down the route of something like:

^.+@.+$

which basically checks you have a value that contains an @. You would then back that up with verification by sending an e-mail to that address.

Any other kind of regex means you risk turning down completely valid e-mail addresses, other than that I agree with the answer provided by @Ben.

I've just made a small jQuery plugin for that: https://github.com/ern0/jquery.create

It follows your syntax:

var myDiv = $.create("div");

DOM node ID can be specified as second parameter:

var secondItem = $.create("div","item2");

Is it serious? No. But this syntax is better than $("<div></div>"), and it's a very good value for that money.

I'm a new jQuery user, switching from DOMAssistant, which has a similar function: http://www.domassistant.com/documentation/DOMAssistantContent-module.php

My plugin is simpler, I think attrs and content is better to add by chaining methods:

$("#container").append( $.create("div").addClass("box").html("Hello, world!") );

Also, it's a good example for a simple jQuery-plugin (the 100th one).

Gradle looks for gradle.properties files in these places:

• in project build dir (that is where your build script is)
• in sub-project dir
• in gradle user home (defined by the GRADLE_USER_HOME environment variable, which if not set defaults to USER_HOME/.gradle)

Properties from one file will override the properties from the previous ones (so file in gradle user home has precedence over the others, and file in sub-project has precedence over the one in project root).

Reference: https://gradle.org/docs/current/userguide/build_environment.html

First off, EC2 and Elastic Compute Cloud are the same thing.

Next, AWS encompasses the range of Web Services that includes EC2 and Elastic Beanstalk. It also includes many others such as S3, RDS, DynamoDB, and all the others.

EC2

EC2 is Amazon's service that allows you to create a server (AWS calls these instances) in the AWS cloud. You pay by the hour and only what you use. You can do whatever you want with this instance as well as launch n number of instances.

Elastic Beanstalk

Elastic Beanstalk is one layer of abstraction away from the EC2 layer. Elastic Beanstalk will setup an "environment" for you that can contain a number of EC2 instances, an optional database, as well as a few other AWS components such as a Elastic Load Balancer, Auto-Scaling Group, Security Group. Then Elastic Beanstalk will manage these items for you whenever you want to update your software running in AWS. Elastic Beanstalk doesn't add any cost on top of these resources that it creates for you. If you have 10 hours of EC2 usage, then all you pay is 10 compute hours.

Running Wordpress

For running Wordpress, it is whatever you are most comfortable with. You could run it straight on a single EC2 instance, you could use a solution from the AWS Marketplace, or you could use Elastic Beanstalk.

What to pick?

In the case that you want to reduce system operations and just focus on the website, then Elastic Beanstalk would be the best choice for that. Elastic Beanstalk supports a PHP stack (as well as others). You can keep your site in version control and easily deploy to your environment whenever you make changes. It will also setup an Autoscaling group which can spawn up more EC2 instances if traffic is growing.

Here's the first result off of Google when searching for "elastic beanstalk wordpress": https://www.otreva.com/blog/deploying-wordpress-amazon-web-services-aws-ec2-rds-via-elasticbeanstalk/

In my case, the app main Target's Team was different from Tests' Target Team. Changing the Tests' Team to the same Team as main Target's solves the issue.

MAMP if you are on a MAC MAMP

You can use the following code;

var example: String = "Hello World \r\n This is a new line"

jQuery's attr method returns the value of the attribute:

The .attr() method gets the attribute value for only the first element in the matched set. To get the value for each element individually, use a looping construct such as jQuery's .each() or .map() method.

All you need is:

$('html').attr('lang') == 'fr-FR'

However, you might want to do a case-insensitive match:

$('html').attr('lang').toLowerCase() === 'fr-fr'

jQuery's val method returns the value of a form element.

The .val() method is primarily used to get the values of form elements such as input, select and textarea. In the case of <select multiple="multiple"> elements, the .val() method returns an array containing each selected option; if no option is selected, it returns null.

Requirements files use an expanded pip format, which is only useful if you need to complement your setup.py with stronger constraints, for example specifying the exact urls some of the dependencies must come from, or the output of pip freeze to freeze the entire package set to known-working versions. If you don't need the extra constraints, use only a setup.py. If you feel like you really need to ship a requirements.txt anyway, you can make it a single line:

.

It will be valid and refer exactly to the contents of the setup.py that is in the same directory.

What we do, is to create two tables for each multilingual object.

E.g. the first table contains only language-neutral data (primary key, etc.) and the second table contains one record per language, containing the localized data plus the ISO code of the language.

In some cases we add a DefaultLanguage field, so that we can fall-back to that language if no localized data is available for a specified language.

Example:

Table "Product":
----------------
ID                 : int
<any other language-neutral fields>


Table "ProductTranslations"
---------------------------
ID                 : int      (foreign key referencing the Product)
Language           : varchar  (e.g. "en-US", "de-CH")
IsDefault          : bit
ProductDescription : nvarchar
<any other localized data>

With this approach, you can handle as many languages as needed (without having to add additional fields for each new language).

Update (2014-12-14): please have a look at this answer, for some additional information about the implementation used to load multilingual data into an application.

I think using nested list comprehensions is the most elegant way to solve this, because the intermediate result is the position where the element is. An implementation would be:

list =[ ['a','b'], ['a','c'], ['b','d'] ]
search = 'c'
any([ (list.index(x),x.index(y)) for x in list for y in x if y == search ] )

Adding a small attribute as android:spinnerMode="dialog" would show the spinner contents in a pop-up.

The python manual provides the following:

import termios, fcntl, sys, os
fd = sys.stdin.fileno()

oldterm = termios.tcgetattr(fd)
newattr = termios.tcgetattr(fd)
newattr[3] = newattr[3] & ~termios.ICANON & ~termios.ECHO
termios.tcsetattr(fd, termios.TCSANOW, newattr)

oldflags = fcntl.fcntl(fd, fcntl.F_GETFL)
fcntl.fcntl(fd, fcntl.F_SETFL, oldflags | os.O_NONBLOCK)

try:
    while 1:
        try:
            c = sys.stdin.read(1)
            print "Got character", repr(c)
        except IOError: pass
finally:
    termios.tcsetattr(fd, termios.TCSAFLUSH, oldterm)
    fcntl.fcntl(fd, fcntl.F_SETFL, oldflags)

which can be rolled into your use case.

You can also use python's requests library instead.

import requests

url = 'http://www.quandl.com/api/v1/datasets/FRED/GDP.json'    
response = requests.get(url)    
dict = response.json()

Now you can manipulate the "dict" like a python dictionary.

The exception is telling that a Bundle_en_US.properties, or Bundle_en.properties, or at least Bundle.properties file is expected in the root of the classpath, but there is actually none.

Make sure that at least one of the mentioned files is present in the root of the classpath. Or, make sure that you provide the proper bundle name. For example, if the bundle files are actually been placed in the package com.example.i18n, then you need to pass com.example.i18n.Bundle as bundle name instead of Bundle.

In case you're using Eclipse "Dynamic Web Project", the classpath root is represented by src folder, there where all your Java packages are. In case you're using a Maven project, the classpath root for resource files is represented by src/main/resources folder.

jdk.tools:jdk.tools (or com.sun:tools, or whatever you name it) is a JAR file that is distributed with JDK. Usually you add it to maven projects like this:

<dependency>
    <groupId>jdk.tools</groupId>
    <artifactId>jdk.tools</artifactId>
    <scope>system</scope>
    <systemPath>${java.home}/../lib/tools.jar</systemPath>
</dependency>

See, the Maven FAQ for adding dependencies to tools.jar

Or, you can manually install tools.jar in the local repository using:

mvn install:install-file -DgroupId=jdk.tools -DartifactId=jdk.tools -Dpackaging=jar -Dversion=1.6 -Dfile=tools.jar -DgeneratePom=true

and then reference it like Cloudera did, using:

<dependency>
    <groupId>jdk.tools</groupId>
    <artifactId>jdk.tools</artifactId>
    <version>1.6</version>
</dependency>

I like Spring MVC, using 2.5 features there is very little XML involved.

\d{1,3} will match numbers like 00 or 333 as well which wouldn't be a valid ID.

This is an excellent answer from smink, citing:

ValidIpAddressRegex = "^(([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])$";

try CAST function in MySQL:

mysql_query("INSERT INTO data_table (title, date_of_event)
VALUES('". $_POST['post_title'] ."',
CAST('". $date ."' AS DATE))") or die(mysql_error()); 

I suspect that the SelectedItem property of the ComboBox does not change until the control has been validated (which occurs when the control loses focus), whereas the SelectedValue property changes whenever the user selects an item.

Here is a reference to the focus events that occur on controls:

http://msdn.microsoft.com/en-us/library/system.windows.forms.control.validated.aspx

NULL isn't a keyword; it's a macro substitution for 0, and comes in stddef.h or cstddef, I believe. You haven't #included an appropriate header file, so g++ sees NULL as a regular variable name, and you haven't declared it.

Never put ListView in ScrollView. ListView itself is scrollable.

I had this identical problem, I was using django-rest-knox for authentication tokens. It turns out that nothing was wrong with my fetch method which looked like this:

...
    let headers = {"Content-Type": "application/json"};
    if (token) {
      headers["Authorization"] = `Token ${token}`;
    }
    return fetch("/api/instruments/", {headers,})
      .then(res => {
...

I was running apache.

What solved this problem for me was changing WSGIPassAuthorization to 'On' in wsgi.conf.

I had a Django app deployed on AWS EC2, and I used Elastic Beanstalk to manage my application, so in the django.config, I did this:

container_commands:
  01wsgipass:
    command: 'echo "WSGIPassAuthorization On" >> ../wsgi.conf'

hyperjaxb (versions 2 and 3) actually generates hibernate mapping files and related entity objects and also does a round trip test for a given XSD and sample XML file. You can capture the log output and see the DDL statements for yourself. I had to tweak them a little bit, but it gives you a basic blue print to start with.

You have some special words from CMAKE, take a look:

if(${CMAKE_SYSTEM_NAME} STREQUAL "Linux")
    // do something for Linux
else
    // do something for other OS

Well I always use the same easy way and it works for me. In your HTML keep the type as text (like this):

<input type="text" class="textfield" value="" id="onlyNumbers" name="onlyNumbers" onkeypress="return isNumber(event)" onpaste="return false;"/>

After this you only need to add a method on javascript

<script type="text/javascript">     
function isNumber(evt) {
        evt = (evt) ? evt : window.event;
        var charCode = (evt.which) ? evt.which : evt.keyCode;
        if ( (charCode > 31 && charCode < 48) || charCode > 57) {
            return false;
        }
        return true;
    }
</script>

With this easy validation you will only get positive numbers as you wanted. You can modify the charCodes to add more valid keys to your method.

Here´s the code working: Only numbers validation

Since 12,200 people have looked at this question and not got an answer:

DFSORT and SyncSort are the predominant Mainframe sorting products. Their control cards have many similarities, and some differences.

JOINKEYS FILE=F1,FIELDS=(key1startpos,7,A)              
JOINKEYS FILE=F2,FIELDS=(key2startpos,7,A)              
JOIN UNPAIRED,F1,F2
REFORMAT FIELDS=(F1:1,5200,F2:1,5200)                         
SORT FIELDS=COPY    

A "JOINKEYS" is made of three Tasks. Sub-Task 1 is the first JOINKEYS. Sub-Task 2 is the second JOINKEYS. The Main Task follows and is where the joined data is processed. In the example above it is a simple COPY operation. The joined data will simply be written to SORTOUT.

The JOIN statement defines that as well as matched records, UNPAIRED F1 and F2 records are to be presented to the Main Task.

The REFORMAT statement defines the record which will be presented to the Main Task. A more efficient example, imagining that three fields are required from F2, is:

 REFORMAT FIELDS=(F1:1,5200,F2:1,10,30,1,5100,100)

Each of the fields on F2 is defined with a start position and a length.

The record which is then processed by the Main task is 5311 bytes long, and the fields from F2 can be referenced by 5201,10,5211,1,5212,100 with the F1 record being 1,5200.

A better way achieve the same thing is to reduce the size of F2 with JNF2CNTL.

//JNF2CNTL DD *
  INREC BUILD=(207,1,10,30,1,5100,100)

Some installations of SyncSort do not support JNF2CNTL, and even where supported (from Syncsort MFX for z/OS release 1.4.1.0 onwards), it is not documented by SyncSort. For users of 1.3.2 or 1.4.0 an update is available from SyncSort to provide JNFnCNTL support.

It should be noted that JOINKEYS by default SORTs the data, with option EQUALS. If the data for a JOINKEYS file is already in sequence, SORTED should be specified. For DFSORT NOSEQCHK can also be specified if sequence-checking is not required.

 JOINKEYS FILE=F1,FIELDS=(key1startpos,7,A),SORTED,NOSEQCHK

Although the request is strange, as the source file won't be able to be determined, all unmatched records are to go to a separate output file.

With DFSORT, there is a matching-marker, specified with ? in the REFORMAT:

 REFORMAT FIELDS=(F1:1,5200,F2:1,10,30,1,5100,100,?)

This increases the length of the REFORMAT record by one byte. The ? can be specified anywhere on the REFORMAT record, and need not be specified. The ? is resolved by DFSORT to: B, data sourced from Both files; 1, unmatched record from F1; 2, unmatched record from F2.

SyncSort does not have the match marker. The absence or presence of data on the REFORMAT record has to be determined by values. Pick a byte on both input records which cannot contain a particular value (for instance, within a number, decide on a non-numeric value). Then specify that value as the FILL character on the REFORMAT.

 REFORMAT FIELDS=(F1:1,5200,F2:1,10,30,1,5100,100),FILL=C'$'

If position 1 on F1 cannot naturally have "$" and position 20 on F2 cannot either, then those two positions can be used to establish the result of the match. The entire record can be tested if necessary, but sucks up more CPU time.

The apparent requirement is for all unmatched records, from either F1 or F2, to be written to one file. This will require a REFORMAT statement which includes both records in their entirety:

DFSORT, output unmatched records:

  REFORMAT FIELDS=(F1:1,5200,F2:1,5200,?)

  OUTFIL FNAMES=NOMATCH,INCLUDE=(10401,1,SS,EQ,C'1,2'),
        IFTHEN=(WHEN=(10401,1,CH,EQ,C'1'),
                    BUILD=(1,5200)),
        IFTHEN=(WHEN=NONE,
                    BUILD=(5201,5200))

SyncSort, output unmatched records:

  REFORMAT FIELDS=(F1:1,5200,F2:1,5200),FILL=C'$'

  OUTFIL FNAMES=NOMATCH,INCLUDE=(1,1,CH,EQ,C'$',
                          OR,5220,1,CH,EQ,C'$'),
        IFTHEN=(WHEN=(1,1,CH,EQ,C'$'),
                    BUILD=(1,5200)),
        IFTHEN=(WHEN=NONE,
                    BUILD=(5201,5200))

The coding for SyncSort will also work with DFSORT.

To get the matched records written is easy.

  OUTFIL FNAMES=MATCH,SAVE

SAVE ensures that all records not written by another OUTFIL will be written here.

There is some reformatting required, to mainly output data from F1, but to select some fields from F2. This will work for either DFSORT or SyncSort:

  OUTFIL FNAMES=MATCH,SAVE,
     BUILD=(1,50,10300,100,51,212,5201,10,263,8,5230,1,271,4929)

The whole thing, with arbitrary starts and lengths is:

DFSORT

  JOINKEYS FILE=F1,FIELDS=(1,7,A)              
  JOINKEYS FILE=F2,FIELDS=(20,7,A)    

  JOIN UNPAIRED,F1,F2

  REFORMAT FIELDS=(F1:1,5200,F2:1,5200,?)                         

  SORT FIELDS=COPY    

  OUTFIL FNAMES=NOMATCH,INCLUDE=(10401,1,SS,EQ,C'1,2'),
        IFTHEN=(WHEN=(10401,1,CH,EQ,C'1'),
                    BUILD=(1,5200)),
        IFTHEN=(WHEN=NONE,
                    BUILD=(5201,5200))

  OUTFIL FNAMES=MATCH,SAVE,
     BUILD=(1,50,10300,100,51,212,5201,10,263,8,5230,1,271,4929)

SyncSort

  JOINKEYS FILE=F1,FIELDS=(1,7,A)              
  JOINKEYS FILE=F2,FIELDS=(20,7,A)              

  JOIN UNPAIRED,F1,F2

  REFORMAT FIELDS=(F1:1,5200,F2:1,5200),FILL=C'$'                         

  SORT FIELDS=COPY    

  OUTFIL FNAMES=NOMATCH,INCLUDE=(1,1,CH,EQ,C'$',
                          OR,5220,1,CH,EQ,C'$'),
        IFTHEN=(WHEN=(1,1,CH,EQ,C'$'),
                    BUILD=(1,5200)),
        IFTHEN=(WHEN=NONE,
                    BUILD=(5201,5200))

  OUTFIL FNAMES=MATCH,SAVE,
     BUILD=(1,50,10300,100,51,212,5201,10,263,8,5230,1,271,4929)

The accepted answers animation does not work on Safari, I've updated it using translate instead of padding-left which makes for a smoother, bulletproof animation.

Also, the accepted answers demo fiddle has a lot of unnecessary styles.

So I created a simple version if you just want to cut and paste the useful code and not spend 5 mins clearing through the demo.

So I have ElementTree 1.2.6 on my box now, and ran the following code against the XML chunk you posted:

import elementtree.ElementTree as ET

tree = ET.parse("test.xml")
doc = tree.getroot()
thingy = doc.find('timeSeries')

print thingy.attrib

and got the following back:

{'name': 'NWIS Time Series Instantaneous Values'}

It appears to have found the timeSeries element without needing to use numerical indices.

What would be useful now is knowing what you mean when you say "it doesn't work." Since it works for me given the same input, it is unlikely that ElementTree is broken in some obvious way. Update your question with any error messages, backtraces, or anything you can provide to help us help you.

Navigate via shell inside of your project folder and run following command:

mvn -U clean install

Usually this should already solve your problem.

If you see a message like this:

Could not resolve dependencies for project :war:0.0.1-SNAPSHOT: Failed to collect dependencies at com.sun.jersey:jersey-server:jar:1.9

Then execute:

export MAVEN_OPTS=-Dhttps.protocols=TLSv1,TLSv1.1,TLSv1.2

followed by:

mvn -U clean install

again to finally update your dependencies.

Afterwards perform clean maven build:

maven clean install

It's not impossible without CSS. For example as a list item:

<li style="border-bottom: 1px dashed"><!--content --></li>

Spring for Android do this using RestTemplate easily:

final String url = "http://192.168.1.50:9000/greeting";
RestTemplate restTemplate = new RestTemplate();
restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
Greeting greeting = restTemplate.getForObject(url, Greeting.class);

I have used many codes from the above mentioned sections for removing index.php form the base url. But it was not working from my end. So, you can use this code which I have used and its working properly.

If you really need to remove index.php from the base URL then just put this code in your htaccess.

RewriteCond %{THE_REQUEST} ^GET.*index\.php [NC]

RewriteRule (.*?)index\.php/*(.*) /$1$2 [R=301,NE,L]

After reading your previous comments, it's clear that you misunderstood the Hash::make function. Hash::make uses bcrypt hashing. By design, this means that every time you run Hash::make('password'), the result will be different (due to random salting). That's why you can't verify the password by simply checking the hashed password against the hashed input.

The proper way to validate a hash is by using:

Hash::check($passwordToCheck, $hashedPassword);

So, for example, your login function would be implemented like this:

public static function login($email, $password) {
    $user = User::whereEmail($email)->first();
    if ( !$user ) return null;  //check if user exists
    if ( Hash::check($password, $user->password) ) {
        return $user;
    } else return null;
}

And then you'd call it like this:

$user = User::login('[email protected]', 'password');
if ( !$user ) echo "Invalid credentials.";
else echo "First name: $user->firstName";

I recommend reviewing the Laravel security documentation, as functions already exist in Laravel to perform this type of authorization.

Furthermore, if your custom-made hashing algorithm generates the same hash every time for a given input, it's a security risk. A good one-way hashing algorithm should use random salting.

New solution with ES6

Default object

object = [{'id': 1}, {'id': 2}, {'id': 3}, {'id': 4}];

Another object

object =  {'id': 5};

Object assign ES6

resultObject = {...obj, ...newobj};

Result

[{'id': 1}, {'id': 2}, {'id': 3}, {'id': 4}, {'id': 5}];

origin/xxx branches are always pointer to a remote. You cannot check them out as they're not pointer to your local repository (you only checkout the commit. That's why you won't see the name written in the command line interface branch marker, only the commit hash).

What you need to do to update the remote is to force push your local changes to master:

git checkout master
git reset --hard e3f1e37
git push --force origin master
# Then to prove it (it won't print any diff)
git diff master..origin/master

I was facing same issue with my one of my feature branch. I tried above mentioned solution nothing worked. I resolved this issue by doing following things.

• git pull origin feature-branch-name
• git push

import java.util.Deque;
import java.util.LinkedList;
import java.util.Queue;

public class ImplementationOfStackUsingTwoQueue {

    private static Deque<Integer> inboxQueue = new LinkedList<>();
    private static Queue<Integer> outboxQueue = new LinkedList<>();
    
    public void pushInStack(Integer val){
        inboxQueue.add(val);
    }
    
    public void popFromStack(){
        
        if(outboxQueue.isEmpty()){
            while(!inboxQueue.isEmpty()){
                outboxQueue.add(inboxQueue.pollLast());
            }
        }
    }
    
    public static void main(String[] args) {
        
        ImplementationOfStackUsingTwoQueue obj = new ImplementationOfStackUsingTwoQueue();
        
        obj.pushInStack(1);
        obj.pushInStack(2);
        obj.pushInStack(3);
        obj.pushInStack(4);
        obj.pushInStack(5);
        System.out.println("After pushing the values in Queue" + inboxQueue);
        
        obj.popFromStack();
        System.out.println("After popping the values from Queue" + outboxQueue);    
    }
}

Following are major difference between HashMap and TreeMap

1. HashMap does not maintain any order. In other words , HashMap does not provide any guarantee that the element inserted first will be printed first, where as Just like TreeSet , TreeMap elements are also sorted according to the natural ordering of its elements

2. Internal HashMap implementation use Hashing and TreeMap internally uses Red-Black tree implementation.

3. HashMap can store one null key and many null values.TreeMap can not contain null keys but may contain many null values.

4. HashMap take constant time performance for the basic operations like get and put i.e O(1).According to Oracle docs , TreeMap provides guaranteed log(n) time cost for the get and put method.

5. HashMap is much faster than TreeMap, as performance time of HashMap is constant against the log time TreeMap for most operations.

6. HashMap uses equals() method in comparison while TreeMap uses compareTo() method for maintaining ordering.

7. HashMap implements Map interface while TreeMap implements NavigableMap interface.

If you just need this functionality and want to use it in more than one controller, this is a simple service to track route history:

  (function () {
  'use strict';

  angular
    .module('core')
    .factory('RouterTracker', RouterTracker);

  function RouterTracker($rootScope) {

    var routeHistory = [];
    var service = {
      getRouteHistory: getRouteHistory
    };

    $rootScope.$on('$stateChangeSuccess', function (ev, to, toParams, from, fromParams) {
      routeHistory.push({route: from, routeParams: fromParams});
    });

    function getRouteHistory() {
      return routeHistory;
    }

    return service;
  }
})();

where the 'core' in .module('core') would be the name of your app/module. Require the service as a dependency to your controller, then in your controller you can do: $scope.routeHistory = RouterTracker.getRouteHistory()

I was facing this issue in a web application hosted on a shared hosting server. So obviously did not have direct access to IIS, so could not apply many solution proposed here.

On the hosting provider's control panel I enabled error logging for IIS and ASP.Net. And then got to know that error actually lied in a missing cshtml.

You could let your DataAdapter do the work. DataAdapter.Fill(DataTable) will append your new rows to any existing rows in DataTable.

A form action set to a JavaScript function is not widely supported, I'm surprised it works in FireFox.

The best is to just set form action to your PHP script; if you need to do anything before submission you can just add to onsubmit

Edit turned out you didn't need any extra function, just a small change here:

function validateFormOnSubmit(theForm) {
    var reason = "";
    reason += validateName(theForm.name);
    reason += validatePhone(theForm.phone);
    reason += validateEmail(theForm.emaile);

    if (reason != "") {
        alert("Some fields need correction:\n" + reason);
    } else {
        simpleCart.checkout();
    }
    return false;
}

Then in your form:

<form action="#" onsubmit="return validateFormOnSubmit(this);">

Here's how I got my bash script for my daily mysqldump database backups to work more securely. This is an expansion of Cristian Porta's great answer.

1. First use mysql_config_editor (comes with mysql 5.6+) to set up the encrypted password file. Suppose your username is "db_user". Running from the shell prompt:

   mysql_config_editor set --login-path=local --host=localhost --user=db_user --password
   

   It prompts for the password. Once you enter it, the user/pass are saved encrypted in your home/system_username/.mylogin.cnf

   Of course, change "system_username" to your username on the server.

2. Change your bash script from this:

   mysqldump -u db_user -pInsecurePassword my_database | gzip > db_backup.tar.gz
   

   to this:

   mysqldump --login-path=local my_database | gzip > db_backup.tar.gz
   

No more exposed passwords.

An updated answer reflecting changed times:

GitPython currently is the easiest to use. It supports wrapping of many git plumbing commands and has pluggable object database (dulwich being one of them), and if a command isn't implemented, provides an easy api for shelling out to the command line. For example:

repo = Repo('.')
repo.checkout(b='new_branch')

This calls:

bash$ git checkout -b new_branch

Dulwich is also good but much lower level. It's somewhat of a pain to use because it requires operating on git objects at the plumbing level and doesn't have nice porcelain that you'd normally want to do. However, if you plan on modifying any parts of git, or use git-receive-pack and git-upload-pack, you need to use dulwich.
