It is very inefficient to store all values in memory, so the objects are reused and loaded one at a time. See this other SO question for a good explanation. Summary:

[...] when looping through the Iterable value list, each Object instance is re-used, so it only keeps one instance around at a given time.

Go to the Declaration of the desired object and mark it Shared.

Facebook Developer Wiki (unofficial) contain not only list of FQL error codes but others too it's somehow updated but not contain full list of possible error codes.

There is no any official or updated (I mean really updated) list of error codes returned by Graph API. Every list that can be found online is outdated and not help that much...

There is official list describing some of API Errors and basic recovery tactics. Also there is couple of offcial lists for specific codes:

• Graph API › Errors
• OAuth Errors
• Credits Error codes - Facebook Credits is unsupported from Sep 2013
• Payments Error codes

Elements have to paint to an integer number of pixels, and as the other answers covered, percentages are indeed respected.

An important note is that pixels in this case means css pixels, not screen pixels, so a 200px container with a 50.7499% child will be rounded to 101px css pixels, which then get rendered onto 202px on a retina screen, and not 400 * .507499 ~= 203px.

Screen density is ignored in this calculation, and there is no way to paint* an element to specific retina subpixel sizes. You can't have elements' backgrounds or borders rendered at less than 1 css pixel size, even though the actual element's size could be less than 1 css pixel as Sandy Gifford showed.

[*] You can use some techniques like 0.5 offset box-shadow, etc, but the actual box model properties will paint to a full CSS pixel.

The easiest way is to redirect the output of the echo by >>:

echo 'VNCSERVERS="1:root"' >> /etc/sysconfig/configfile
echo 'VNCSERVERARGS[1]="-geometry 1600x1200"' >> /etc/sysconfig/configfile

Pre-201x answer

The benchmark code of @cd1 and other answers are wrong. b.N is not supposed to be set in benchmark function. It's set by the go test tool dynamically to determine if the execution time of the test is stable.

A benchmark function should run the same test b.N times and the test inside the loop should be the same for each iteration. So I fix it by adding an inner loop. I also add benchmarks for some other solutions:

Conclusion:

1. CopyPreAllocate is the fastest way; AppendPreAllocate is pretty close to No.1, but it's easier to write the code.
2. Concat has really bad performance both for speed and memory usage. Don't use it.
3. Buffer#Write and Buffer#WriteString are basically the same in speed, contrary to what @Dani-Br said in the comment. Considering string is indeed []byte in Go, it makes sense.
4. bytes.Buffer basically use the same solution as Copy with extra book keeping and other stuff.
5. Copy and Append use a bootstrap size of 64, the same as bytes.Buffer
6. Append use more memory and allocs, I think it's related to the grow algorithm it use. It's not growing memory as fast as bytes.Buffer

Suggestion:

1. For simple task such as what OP wants, I would use Append or AppendPreAllocate. It's fast enough and easy to use.
2. If need to read and write the buffer at the same time, use bytes.Buffer of course. That's what it's designed for.

Try this small solution:

$("#some_id").attr("checked") ? 1 : 0;

or

$("#some_id").attr("checked") || 0;

It breaks pages using XML rendering (like XHTML pages).

Best: some browser switch back to HTML rendering and everything works fine.

Probable: some browser disable the document.write() function in XML rendering mode.

Worst: some browser will fire an XML error whenever using the document.write() function.

If you are looking for the solution in Android Studio :

1. Right click on your app
2. Open Module Settings
3. Select Dependencies tab
4. Click on green + symbol which is on the right side
5. Select Library Dependency
6. Choose appcompat-v7 from list

Did you set the CSS:

html, body
{
    height: 100%;
}

You need this to be able to make the div take up all the space. :)

String.prototype.charCodeAt() can convert string characters to ASCII numbers. For example:

"ABC".charCodeAt(0) // returns 65

For opposite use String.fromCharCode(10) that convert numbers to equal ASCII character. This function can accept multiple numbers and join all the characters then return the string. Example:

String.fromCharCode(65,66,67); // returns 'ABC'

Here is a quick ASCII characters reference:

bad:

good:

better:

<a id="myLink" href="#" onclick="MyFunction();return false;">link text</a>

even better 1:

<a id="myLink" title="Click to do something"
 href="#" onclick="MyFunction();return false;">link text</a>

even better 2:

<a id="myLink" title="Click to do something"
 href="PleaseEnableJavascript.html" onclick="MyFunction();return false;">link text</a>

Why better? because return false will prevent browser from following the link

best:

Use jQuery or other similar framework to attach onclick handler by element's ID.

$('#myLink').click(function(){ MyFunction(); return false; });

Q: What is std::move?

A: std::move() is a function from the C++ Standard Library for casting to a rvalue reference.

Simplisticly std::move(t) is equivalent to:

static_cast<T&&>(t);

An rvalue is a temporary that does not persist beyond the expression that defines it, such as an intermediate function result which is never stored in a variable.

int a = 3; // 3 is a rvalue, does not exist after expression is evaluated
int b = a; // a is a lvalue, keeps existing after expression is evaluated

An implementation for std::move() is given in N2027: "A Brief Introduction to Rvalue References" as follows:

template <class T>
typename remove_reference<T>::type&&
std::move(T&& a)
{
    return a;
}

As you can see, std::move returns T&& no matter if called with a value (T), reference type (T&), or rvalue reference (T&&).

Q: What does it do?

A: As a cast, it does not do anything during runtime. It is only relevant at compile time to tell the compiler that you would like to continue considering the reference as an rvalue.

foo(3 * 5); // obviously, you are calling foo with a temporary (rvalue)

int a = 3 * 5;
foo(a);     // how to tell the compiler to treat `a` as an rvalue?
foo(std::move(a)); // will call `foo(int&& a)` rather than `foo(int a)` or `foo(int& a)`

What it does not do:

• Make a copy of the argument
• Call the copy constructor
• Change the argument object

Q: When should it be used?

A: You should use std::move if you want to call functions that support move semantics with an argument which is not an rvalue (temporary expression).

This begs the following follow-up questions for me:

• What is move semantics? Move semantics in contrast to copy semantics is a programming technique in which the members of an object are initialized by 'taking over' instead of copying another object's members. Such 'take over' makes only sense with pointers and resource handles, which can be cheaply transferred by copying the pointer or integer handle rather than the underlying data.

• What kind of classes and objects support move semantics? It is up to you as a developer to implement move semantics in your own classes if these would benefit from transferring their members instead of copying them. Once you implement move semantics, you will directly benefit from work from many library programmers who have added support for handling classes with move semantics efficiently.

• Why can't the compiler figure it out on its own? The compiler cannot just call another overload of a function unless you say so. You must help the compiler choose whether the regular or move version of the function should be called.

• In which situations would I want to tell the compiler that it should treat a variable as an rvalue? This will most likely happen in template or library functions, where you know that an intermediate result could be salvaged.

Copy the global variable to a variable in the scope in your controller.

function MyCtrl($scope) {
   $scope.variable1 = variable1;
}

Then you can just access it like you tried. But note that this variable will not change when you change the global variable. If you need that, you could instead use a global object and "copy" that. As it will be "copied" by reference, it will be the same object and thus changes will be applied (but remember that doing stuff outside of AngularJS will require you to do $scope.$apply anway).

But maybe it would be worthwhile if you would describe what you actually try to achieve. Because using a global variable like this is almost never a good idea and there is probably a better way to get to your intended result.

I think this will help : In Controller get the list items and selected value

public ActionResult Edit(int id)
{
    ItemsStore item = itemStoreRepository.FindById(id);
    ViewBag.CategoryId = new SelectList(categoryRepository.Query().Get(), 
                                        "Id", "Name",item.CategoryId);

    // ViewBag to pass values to View and SelectList
    //(get list of items,valuefield,textfield,selectedValue)

    return View(item);
}

and in View

@Html.DropDownList("CategoryId",String.Empty)

If you do not want to use DecimalFormat (e.g. due to its efficiency) and you want a general solution, you could also try this method that uses scaled rounding:

public static double roundToDigits(double value, int digitCount) {
    if (digitCount < 0)
        throw new IllegalArgumentException("Digit count must be positive for rounding!");

    double factor = Math.pow(10, digitCount);
    return (double)(Math.round(value * factor)) / factor;
}

If you used Mac OS and Brew try this:

mkdir /usr/local/etc/my.cnf.d

Although probably not the best method you could add:

#div1 {
    ...
    font-size:0;
}

I know this thread is old, but I thought I'd put in my two cents. You don't need to make a custom animation, there's a simple (maybe hacky) way of doing it. Instead of using push, create a new navigation controller, make the new view controller the root view controller of that nav controller, and then present the nav controller from the original nav controller. Present is easily customizable with many styles, and no need to make a custom animation.

For example:

UIViewcontroller viewControllerYouWantToPush = UIViewController()
UINavigationController newNavController = UINavigationController(root: viewControllerYouWantToView)
newNavController.navBarHidden = YES;
self.navigationController.present(newNavController)

And you can change the presentation style however you want.

Using the standard mysql.createPool(), connections are lazily created by the pool. If you configure the pool to allow up to 100 connections, but only ever use 5 simultaneously, only 5 connections will be made. However if you configure it for 500 connections and use all 500 they will remain open for the durations of the process, even if they are idle!

This means if your MySQL Server max_connections is 510 your system will only have 10 mySQL connections available until your MySQL Server closes them (depends on what you have set your wait_timeout to) or your application closes! The only way to free them up is to manually close the connections via the pool instance or close the pool.

mysql-connection-pool-manager module was created to fix this issue and automatically scale the number of connections dependant on the load. Inactive connections are closed and idle connection pools are eventually closed if there has not been any activity.

    // Load modules
const PoolManager = require('mysql-connection-pool-manager');

// Options
const options = {
  ...example settings
}

// Initialising the instance
const mySQL = PoolManager(options);

// Accessing mySQL directly
var connection = mySQL.raw.createConnection({
  host     : 'localhost',
  user     : 'me',
  password : 'secret',
  database : 'my_db'
});

// Initialising connection
connection.connect();

// Performing query
connection.query('SELECT 1 + 1 AS solution', function (error, results, fields) {
  if (error) throw error;
  console.log('The solution is: ', results[0].solution);
});

// Ending connection
connection.end();

META-INF in Maven

In Maven the META-INF folder is understood because of the Standard Directory Layout, which by name convention package your project resources within JARs: any directories or files placed within the ${basedir}/src/main/resources directory are packaged into your JAR with the exact same structure starting at the base of the JAR. The Folder ${basedir}/src/main/resources/META-INF usually contains .properties files while in the jar contains a generated MANIFEST.MF, pom.properties, the pom.xml, among other files. Also frameworks like Spring use classpath:/META-INF/resources/ to serve web resources. For more information see How do I add resources to my Maven Project.

All the consumers per topic

(Replace --zookeeper with --bootstrap-server to get groups stored by newer Kafka clients)

Get all consumers-per-topic as a table of topictabconsumer:

for t in `kafka-consumer-groups.sh --zookeeper <HOST>:2181 --list 2>/dev/null`; do
    echo $t | xargs -I {} sh -c "kafka-consumer-groups.sh --zookeeper <HOST>:2181 --describe --group {} 2>/dev/null | grep ^{} | awk '{print \$2\"\t\"\$1}' "
done > topic-consumer.txt

Make this pairs unique:

cat topic-consumer.txt | sort -u > topic-consumer-u.txt

Get the desired one:

less topic-consumer-u.txt | grep -i <TOPIC>

I'd use minlog, personally. It's extremely simple, as the logging class is a few hundred lines of code.

prods.Remove(prods.Single(p=>p.ID == 1));

you can't modify collection in foreach, as Vincent suggests

db.<COLLECTION NAME>.find({ "<FIELD NAME>": { $exists: true, $ne: null } })

In my computer there wasn't a uninstaller in the Start Menu as well. But it worked it the Control Panel > Programs > Uninstall a Program, and selecting Python(Anaconda64bits) in the menu. (Note that I'm using Win10)

You can use document.write or even console.write (this is good for debugging).

But your best bet and it gives you more control is to use DOM to update the page.

Besides the "accented letters are sorted differently than unaccented ones" in some Western European languages, you must take into account the groups of letters, which sometimes are sorted differently, also.

Traditionally, in Spanish, "ch" was considered a letter in its own right, same with "ll" (both of which represent a single phoneme), so a list would get sorted like this:

• caballo
• cinco
• coche
• charco
• chocolate
• chueco
• dado
• (...)
• lámpara
• luego
• llanta
• lluvia
• madera

Notice all the words starting with single c go together, except words starting with ch which go after them, same with ll-starting words which go after all the words starting with a single l. This is the ordering you'll see in old dictionaries and encyclopedias, sometimes even today by very conservative organizations.

The Royal Academy of the Language changed this to make it easier for Spanish to be accomodated in the computing world. Nevertheless, ñ is still considered a different letter than n and goes after it, and before o. So this is a correctly ordered list:

• Namibia
• número
• ñandú
• ñú
• obra
• ojo

By selecting the correct collation, you get all this done for you, automatically :-)

As per my usage above v.4 this gonna work

$('#selectID').on("select2:select", function(e) { 
    //var value = e.params.data;  Using {id,text format}
});

And for less then v.4 this gonna work:

$('#selectID').on("change", function(e) { 
   //var value = e.params.data; Using {id,text} format
});

Pass by pointer is the only way you could pass "by reference" in C, so you still see it used quite a bit.

The NULL pointer is a handy convention for saying a parameter is unused or not valid, so use a pointer in that case.

References can't be updated once they're set, so use a pointer if you ever need to reassign it.

Prefer a reference in every case where there isn't a good reason not to. Make it const if you can.

You can use the root.configure(background='your colour') example:- import tkinter root=tkiner.Tk() root.configure(background='pink')

handler = urllib2.HTTPBasicAuthHandler(manager)

director = urllib2.OpenerDirector()
director.add_handler(handler)

req = urllib2.Request('https://app.streamsend.com/emails', headers = {'Accept' : 'application/xml'})

result = director.open(req)
# result.read() will contain the data
# result.info() will contain the HTTP headers

# To get say the content-length header
length = result.info()['Content-Length']

Your cURL call using urllib2 instead. Completely untested.

You can do it without having to keep track of the previous scroll top, as all the other examples require:

$(window).bind('mousewheel', function(event) {
    if (event.originalEvent.wheelDelta >= 0) {
        console.log('Scroll up');
    }
    else {
        console.log('Scroll down');
    }
});

I am not an expert on this so feel free to research it further, but it appears that when you use $(element).scroll, the event being listened for is a 'scroll' event.

But if you specifically listen for a mousewheel event by using bind, the originalEvent attribute of the event parameter to your callback contains different information. Part of that information is wheelDelta. If it's positive, you moved the mousewheel up. If it's negative, you moved the mousewheel down.

My guess is that mousewheel events will fire when the mouse wheel turns, even if the page does not scroll; a case in which 'scroll' events probably are not fired. If you want, you can call event.preventDefault() at the bottom of your callback to prevent the page from scrolling, and so that you can use the mousewheel event for something other than a page scroll, like some type of zoom functionality.

You are using a wrong overload of the Html.ActionLink helper. What you think is routeValues is actually htmlAttributes! Just look at the generated HTML, you will see that this anchor's href property doesn't look as you expect it to look.

Here's what you are using:

@Html.ActionLink(
    "Reply",                                                  // linkText
    "BlogReplyCommentAdd",                                    // actionName
    "Blog",                                                   // routeValues
    new {                                                     // htmlAttributes
        blogPostId = blogPostId, 
        replyblogPostmodel = Model, 
        captchaValid = Model.AddNewComment.DisplayCaptcha 
    }
)

and here's what you should use:

@Html.ActionLink(
    "Reply",                                                  // linkText
    "BlogReplyCommentAdd",                                    // actionName
    "Blog",                                                   // controllerName
    new {                                                     // routeValues
        blogPostId = blogPostId, 
        replyblogPostmodel = Model, 
        captchaValid = Model.AddNewComment.DisplayCaptcha 
    },
    null                                                      // htmlAttributes
)

Also there's another very serious issue with your code. The following routeValue:

replyblogPostmodel = Model

You cannot possibly pass complex objects like this in an ActionLink. So get rid of it and also remove the BlogPostModel parameter from your controller action. You should use the blogPostId parameter to retrieve the model from wherever this model is persisted, or if you prefer from wherever you retrieved the model in the GET action:

public ActionResult BlogReplyCommentAdd(int blogPostId, bool captchaValid)
{
    BlogPostModel model = repository.Get(blogPostId);
    ...
}

As far as your initial problem is concerned with the wrong overload I would recommend you writing your helpers using named parameters:

@Html.ActionLink(
    linkText: "Reply",
    actionName: "BlogReplyCommentAdd",
    controllerName: "Blog",
    routeValues: new {
        blogPostId = blogPostId, 
        captchaValid = Model.AddNewComment.DisplayCaptcha
    },
    htmlAttributes: null
)

Now not only that your code is more readable but you will never have confusion between the gazillions of overloads that Microsoft made for those helpers.

If you google for sort order windows explorer you will find out that Windows Explorer (since Windows XP) obviously uses the function StrCmpLogicalW in the sort order "by name". I did not find information about the treatment of the underscore character. I was amused by the following note in the documentation:

Behavior of this function, and therefore the results it returns, can change from release to release. ...

You seem to be unnecessarily setting properties on your ComboBox. You can remove the DisplayMemberPath and SelectedValuePath properties which have different uses. It might be an idea for you to take a look at the Difference between SelectedItem, SelectedValue and SelectedValuePath post here for an explanation of these properties. Try this:

<ComboBox Name="cbxSalesPeriods"
    ItemsSource="{Binding SalesPeriods}"
    SelectedItem="{Binding SelectedSalesPeriod}"
    IsSynchronizedWithCurrentItem="True"/>

Furthermore, it is pointless using your displayPeriod property, as the WPF Framework would call the ToString method automatically for objects that it needs to display that don't have a DataTemplate set up for them explicitly.

UPDATE >>>

As I can't see all of your code, I cannot tell you what you are doing wrong. Instead, all I can do is to provide you with a complete working example of how to achieve what you want. I've removed the pointless displayPeriod property and also your SalesPeriodVO property from your class as I know nothing about it... maybe that is the cause of your problem??. Try this:

public class SalesPeriodV
{
    private int month, year;

    public int Year
    {
        get { return year; }
        set
        {
            if (year != value)
            {
                year = value;
                NotifyPropertyChanged("Year");
            }
        }
    }

    public int Month
    {
        get { return month; }
        set
        {
            if (month != value)
            {
                month = value;
                NotifyPropertyChanged("Month");
            }
        }
    }

    public override string ToString()
    {
        return String.Format("{0:D2}.{1}", Month, Year);
    }

    public virtual event PropertyChangedEventHandler PropertyChanged;
    protected virtual void NotifyPropertyChanged(params string[] propertyNames)
    {
        if (PropertyChanged != null)
        {
            foreach (string propertyName in propertyNames) PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
            PropertyChanged(this, new PropertyChangedEventArgs("HasError"));
        }
    }
}

Then I added two properties into the view model:

private ObservableCollection<SalesPeriodV> salesPeriods = new ObservableCollection<SalesPeriodV>();
public ObservableCollection<SalesPeriodV> SalesPeriods
{
    get { return salesPeriods; }
    set { salesPeriods = value; NotifyPropertyChanged("SalesPeriods"); }
}
private SalesPeriodV selectedItem = new SalesPeriodV();
public SalesPeriodV SelectedItem
{
    get { return selectedItem; }
    set { selectedItem = value; NotifyPropertyChanged("SelectedItem"); }
}

Then initialised the collection with your values:

SalesPeriods.Add(new SalesPeriodV() { Month = 3, Year = 2013 } );
SalesPeriods.Add(new SalesPeriodV() { Month = 4, Year = 2013 } );

And then data bound only these two properties to a ComboBox:

<ComboBox ItemsSource="{Binding SalesPeriods}" SelectedItem="{Binding SelectedItem}" />

That's it... that's all you need for a perfectly working example. You should see that the display of the items comes from the ToString method without your displayPeriod property. Hopefully, you can work out your mistakes from this code example.

For my case, I was trying to execute procedure code in MySQL, and due to some issue with server in which Server can't figure out where to end the statement I was getting Error Code 1064. So I wrapped the procedure with custom DELIMITER and it worked fine.

For example, Before it was:

DROP PROCEDURE IF EXISTS getStats;
CREATE PROCEDURE `getStats` (param_id INT, param_offset INT, param_startDate datetime, param_endDate datetime)
BEGIN
    /*Procedure Code Here*/
END;

After putting DELIMITER it was like this:

DROP PROCEDURE IF EXISTS getStats;
DELIMITER $$
CREATE PROCEDURE `getStats` (param_id INT, param_offset INT, param_startDate datetime, param_endDate datetime)
BEGIN
    /*Procedure Code Here*/
END;
$$
DELIMITER ;

When making an Android app in eclipse, just right-click on the res folder, click New -> Other, and select Android Icon Set under Android.

This allows you to make more icons (or replace any existing ones) easily.

According to: Java Revisited

1. Resources included by include directive are loaded during jsp translation time, while resources included by include action are loaded during request time.

2. Any change on included resources will not be visible in case of include directive until jsp file compiles again. While in case of include action, any change in included resource will be visible in the next request.

3. Include directive is static import, while include action is dynamic import.

4. Include directive uses file attribute to specify resources to be included while include action uses page attribute for the same purpose.

Tabulator is a set of unix command line tools to work with csv files that have header lines. Here is an example to extract columns by name from a file test.csv:

name,sex,house_nr,height,shoe_size
arthur,m,42,181,11.5
berta,f,101,163,8.5
chris,m,1333,175,10
don,m,77,185,12.5
elisa,f,204,166,7

Then tblmap -k name,height test.csv produces

name,height
arthur,181
berta,163
chris,175
don,185
elisa,166

chunks = [data[100*i:100*(i+1)] for i in range(len(data)/100 + 1)]

This is equivalent to the accepted answer. For example, shortening to batches of 10 for readability:

data = range(35)
print [data[x:x+10] for x in xrange(0, len(data), 10)]
print [data[10*i:10*(i+1)] for i in range(len(data)/10 + 1)]

Outputs:

[[0, 1, 2, 3, 4, 5, 6, 7, 8, 9], [10, 11, 12, 13, 14, 15, 16, 17, 18, 19], [20, 21, 22, 23, 24, 25, 26, 27, 28, 29], [30, 31, 32, 33, 34]]
[[0, 1, 2, 3, 4, 5, 6, 7, 8, 9], [10, 11, 12, 13, 14, 15, 16, 17, 18, 19], [20, 21, 22, 23, 24, 25, 26, 27, 28, 29], [30, 31, 32, 33, 34]]

All of above regex unfortunately didn't worked for me. A strong password's basic rules are

• Should contain at least a capital letter
• Should contain at least a small letter
• Should contain at least a number
• Should contain at least a special character
• And minimum length

So, Best Regex would be

^(?=.*[a-z])(?=.*[A-Z])(?=.*[0-9])(?=.*[!@#\$%\^&\*]).{8,}$

The above regex have minimum length of 8. You can change it from {8,} to {any_number,}

Modification in rules?

let' say you want minimum x characters small letters, y characters capital letters, z characters numbers, Total minimum length w. Then try below regex

^(?=.*[a-z]{x,})(?=.*[A-Z]{y,})(?=.*[0-9]{z,})(?=.*[!@#\$%\^&\*]).{w,}$

Note: Change x, y, z, w in regex

Edit: Updated regex answer

Edit2: Added modification

If you have the vim package installed on your Cygwin install, you can use vim to fix this without find & replace. Start vim as follows: vim filename.sh (often it is aliased to vi also). Then, type :set fileformat=unix, then :wq (write & quit) to save your changes. (The : puts you in vim's edit mode.)

I recommend this over dos2unix since vim is probably more commonly installed.

However, it is probably a best practice to set your text editor to save files that you plan to use in a Unix/Linux environment to have a Unix text format. The answers given above for Notepad++ are a good example.

Additional note: If you are unsure what type a file is (DOS or Unix), you may use the file filename.sh. This can especially help in debugging more obscure issues (such as encoding issues when importing SQL dumps that come from Windows).

For other options on how to modify text file formatting, see this IU knowledge base article

Just increasing max_connections is bad idea. You need to increase shared_buffers and kernel.shmmax as well.

Considerations

max_connections determines the maximum number of concurrent connections to the database server. The default is typically 100 connections.

Before increasing your connection count you might need to scale up your deployment. But before that, you should consider whether you really need an increased connection limit.

Each PostgreSQL connection consumes RAM for managing the connection or the client using it. The more connections you have, the more RAM you will be using that could instead be used to run the database.

A well-written app typically doesn't need a large number of connections. If you have an app that does need a large number of connections then consider using a tool such as pg_bouncer which can pool connections for you. As each connection consumes RAM, you should be looking to minimize their use.

How to increase max connections

1. Increase max_connection and shared_buffers

in /var/lib/pgsql/{version_number}/data/postgresql.conf

change

max_connections = 100
shared_buffers = 24MB

to

max_connections = 300
shared_buffers = 80MB

The shared_buffers configuration parameter determines how much memory is dedicated to PostgreSQL to use for caching data.

• If you have a system with 1GB or more of RAM, a reasonable starting value for shared_buffers is 1/4 of the memory in your system.
• it's unlikely you'll find using more than 40% of RAM to work better than a smaller amount (like 25%)
• Be aware that if your system or PostgreSQL build is 32-bit, it might not be practical to set shared_buffers above 2 ~ 2.5GB.
• Note that on Windows, large values for shared_buffers aren't as effective, and you may find better results keeping it relatively low and using the OS cache more instead. On Windows the useful range is 64MB to 512MB.

2. Change kernel.shmmax

You would need to increase kernel max segment size to be slightly larger than the shared_buffers.

In file /etc/sysctl.conf set the parameter as shown below. It will take effect when postgresql reboots (The following line makes the kernel max to 96Mb)

kernel.shmmax=100663296

Tuning Your PostgreSQL Server

If returning an array works and returning a single object doesn't, you might also try returning your single object as an array containing that single object:

[ { title: "One", key: "1" } ]

that way you are returning a consistent data structure, an array of objects, no matter the data payload.

i see that you've tried wrapping your single object in "parenthesis", and suggest this with example because of course JavaScript treats [ .. ] differently than ( .. )

You can use Httpful :

Github : https://github.com/nategood/httpful

Run the script every 15 minutes of the hour. For example, you want to receive 15 minute stock price quotes, which are updated every 15 minutes.

while True:
    print("Update data:", datetime.now())
    sleep = 15 - datetime.now().minute % 15
    if sleep == 15:
        run_strategy()
        time.sleep(sleep * 60)
    else:
        time.sleep(sleep * 60)

You can remove bullets by setting the list-style-type to none on the CSS for the parent element (typically a <ul>), for example:

ul {
  list-style-type: none;
}

You might also want to add padding: 0 and margin: 0 to that if you want to remove indentation as well.

See Listutorial for a great walkthrough of list formatting techniques.

Before using chunksize option if you want to be sure about the process function that you want to write inside the chunking for-loop as mentioned by @unutbu you can simply use nrows option.

small_df = pd.read_csv(filename, nrows=100)

Once you are sure that the process block is ready, you can put that in the chunking for loop for the entire dataframe.

Just to share my experience

It was caused by the Sharing > Internet Sharing inside System Preferences

I was testing and created NAT64 Network unchecking it solved my problem.

The right way is to fix the overflow, but....

You can give yourself a bigger stack:-

using System.Threading;
Thread T = new Thread(threadDelegate, stackSizeInBytes);
T.Start();

You can use System.Diagnostics.StackTrace FrameCount property to count the frames you've used and throw your own exception when a frame limit is reached.

Or, you can calculate the size of the stack remaining and throw your own exception when it falls below a threshold:-

class Program
{
    static int n;
    static int topOfStack;
    const int stackSize = 1000000; // Default?

    // The func is 76 bytes, but we need space to unwind the exception.
    const int spaceRequired = 18*1024; 

    unsafe static void Main(string[] args)
    {
        int var;
        topOfStack = (int)&var;

        n=0;
        recurse();
    }

    unsafe static void recurse()
    {
        int remaining;
        remaining = stackSize - (topOfStack - (int)&remaining);
        if (remaining < spaceRequired)
            throw new Exception("Cheese");
        n++;
        recurse();
    }
}

Just catch the Cheese. ;)

let suppose ,

data = {};

if( if(!$.isEmptyObject(data)))
{
     document.write("Object is empty);
}

else{
    document.write("Object is not empty);
}

It worked for me and its an easy way to check if object is empty or not

I don't think this DateTimePicker has been mentioned before:

A WPF DateTimePicker That Works Like the One in Winforms

That one is in VB and has some bugs. I converted it to C# and made a new version with bug fixes.

Note: I used the Calendar control in WPFToolkit so that I could use .NET 3.5 instead of .NET 4. If you are using .NET 4, just remove references to "wpftc" in the XAML.

For SQL Server 2005+, if there is no insert trigger, then change the insert statement (all one line, split for clarity here) to this

INSERT INTO aspnet_GameProfiles(UserId,GameId)
OUTPUT INSERTED.ID
VALUES(@UserId, @GameId)

For SQL Server 2000, or if there is an insert trigger:

INSERT INTO aspnet_GameProfiles(UserId,GameId) 
VALUES(@UserId, @GameId);
SELECT SCOPE_IDENTITY()

And then

 Int32 newId = (Int32) myCommand.ExecuteScalar();

You have 3 choices:

1. atoi

This is probably the fastest if you're using it in performance-critical code, but it does no error reporting. If the string does not begin with an integer, it will return 0. If the string contains junk after the integer, it will convert the initial part and ignore the rest. If the number is too big to fit in int, the behaviour is unspecified.

2. sscanf

Some error reporting, and you have a lot of flexibility for what type to store (signed/unsigned versions of char/short/int/long/long long/size_t/ptrdiff_t/intmax_t).

The return value is the number of conversions that succeed, so scanning for "%d" will return 0 if the string does not begin with an integer. You can use "%d%n" to store the index of the first character after the integer that's read in another variable, and thereby check to see if the entire string was converted or if there's junk afterwards. However, like atoi, behaviour on integer overflow is unspecified.

3. strtol and family

Robust error reporting, provided you set errno to 0 before making the call. Return values are specified on overflow and errno will be set. You can choose any number base from 2 to 36, or specify 0 as the base to auto-interpret leading 0x and 0 as hex and octal, respectively. Choices of type to convert to are signed/unsigned versions of long/long long/intmax_t.

If you need a smaller type you can always store the result in a temporary long or unsigned long variable and check for overflow yourself.

Since these functions take a pointer to pointer argument, you also get a pointer to the first character following the converted integer, for free, so you can tell if the entire string was an integer or parse subsequent data in the string if needed.

Personally, I would recommend the strtol family for most purposes. If you're doing something quick-and-dirty, atoi might meet your needs.

As an aside, sometimes I find I need to parse numbers where leading whitespace, sign, etc. are not supposed to be accepted. In this case it's pretty damn easy to roll your own for loop, eg.,

for (x=0; (unsigned)*s-'0'<10; s++) 
    x=10*x+(*s-'0');

Or you can use (for robustness):

if (isdigit(*s))
    x=strtol(s, &s, 10);
else /* error */ 

Not sure about List<T> but Arrays are certainly do-able. And a little bit of magic makes it really easy to get to a List again.

public class UserHolder {
   [XmlElement("list")]
   public User[] Users { get; set; }

   [XmlIgnore]
   public List<User> UserList { get { return new List<User>(Users); } }
}

? extends HasWord

means "A class/interface that extends HasWord." In other words, HasWord itself or any of its children... basically anything that would work with instanceof HasWord plus null.

In more technical terms, ? extends HasWord is a bounded wildcard, covered in Item 31 of Effective Java 3rd Edition, starting on page 139. The same chapter from the 2nd Edition is available online as a PDF; the part on bounded wildcards is Item 28 starting on page 134.

Update: PDF link was updated since Oracle removed it a while back. It now points to the copy hosted by the Queen Mary University of London's School of Electronic Engineering and Computer Science.

Update 2: Lets go into a bit more detail as to why you'd want to use wildcards.

If you declare a method whose signature expect you to pass in List<HasWord>, then the only thing you can pass in is a List<HasWord>.

However, if said signature was List<? extends HasWord> then you could pass in a List<ChildOfHasWord> instead.

Note that there is a subtle difference between List<? extends HasWord> and List<? super HasWord>. As Joshua Bloch put it: PECS = producer-extends, consumer-super.

What this means is that if you are passing in a collection that your method pulls data out from (i.e. the collection is producing elements for your method to use), you should use extends. If you're passing in a collection that your method adds data to (i.e. the collection is consuming elements your method creates), it should use super.

This may sound confusing. However, you can see it in List's sort command (which is just a shortcut to the two-arg version of Collections.sort). Instead of taking a Comparator<T>, it actually takes a Comparator<? super T>. In this case, the Comparator is consuming the elements of the List in order to reorder the List itself.

Late to the party, but if you don't want to expose environment variables, I guess it's easier to do something like this:

RUN echo 1 > /tmp/__var_1
RUN echo `cat /tmp/__var_1`
RUN rm -f /tmp/__var_1

I ended up doing it because we host private npm packages in aws codeartifact:

RUN aws codeartifact get-authorization-token --output text > /tmp/codeartifact.token
RUN npm config set //company-123456.d.codeartifact.us-east-2.amazonaws.com/npm/internal/:_authToken=`cat /tmp/codeartifact.token`
RUN rm -f /tmp/codeartifact.token

And here ARG cannot work and i don't want to use ENV because i don't want to expose this token to anything else

In .Net 4, you can use the multipleSiteBindingsEnabled option:

<system.serviceModel>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true">
    </serviceHostingEnvironment>
</system.serviceModel>

Then, you won't have to specify each address.

For WINDOWS users: FILE-->SETTingS-->EDITOR-->FONT.

Since you need to handle the date string before it is converted to a date in your model, I'd override the accessor for that field

Let's say your date field is published_date. Add this to your model object:

def published_date=(value)
    # do sanity checking here
    # then hand it back to rails to convert and store
    self.write_attribute(:published_date, value) 
end

git checkout -f

must work, if your previous state is clean.

With Hibernate 5.2, you can now force the UTC time zone using the following configuration property:

<property name="hibernate.jdbc.time_zone" value="UTC"/>

"...by a class and a div."

I assume when you say "div" you mean "id"? Try this:

$('#test2.test1').prop('checked', true);

No need to muck about with your [attributename=value] style selectors because id has its own format as does class, and they're easily combined although given that id is supposed to be unique it should be enough on its own unless your meaning is "select that element only if it currently has the specified class".

Or more generally to select an input where you want to specify a multiple attribute selector:

$('input:radio[class=test1][id=test2]').prop('checked', true);

That is, list each attribute with its own square brackets.

Note that unless you have a pretty old version of jQuery you should use .prop() rather than .attr() for this purpose.

You can do something like this:

    public myform()
    {
         InitializeComponent(); // this will be called in ComboBox ComboBox = new System.Windows.Forms.ComboBox();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        // TODO: This line of code loads data into the 'myDataSet.someTable' table. You can move, or remove it, as needed.
        this.myTableAdapter.Fill(this.myDataSet.someTable);
        comboBox1.SelectedItem = null;
        comboBox1.SelectedText = "--select--";           
    }

This is the solution from Rajesh, without the inconvenient commented by yuji, and updated for React Router 4.

The code would be like this:

<Route path="comments" render={(props) => <Comments myProp="value" {...props}/>}/>

Note that I use render instead of component. The reason is to avoid undesired remounting. I also pass the props to that method, and I use the same props on the Comments component with the object spread operator (ES7 proposal).

In general, this is probably not a great idea, since your html file should only be loading JS files that they actually make use of. Regardless, this would be trivial to do with any server-side scripting language. Just insert the script tags before serving the pages to the client.

If you want to do it without using server-side scripting, you could drop your JS files into a directory that allows listing the directory contents, and then use XMLHttpRequest to read the contents of the directory, and parse out the file names and load them.

Option #3 is to have a "loader" JS file that uses getScript() to load all of the other files. Put that in a script tag in all of your html files, and then you just need to update the loader file whenever you upload a new script.

There is another code that's works for me (jQuery).

Not sure if this is the most efficient answer, but it works for me:

import os
import glob
from PIL import Image
Image.MAX_IMAGE_PIXELS = None # to avoid image size warning

imgdir = "/path/to/image/folder"
# if you want file of a specific extension (.png):
filelist = [f for f in glob.glob(imgdir + "**/*.png", recursive=True)]
savedir = "/path/to/image/folder/output"

start_pos = start_x, start_y = (0, 0)
cropped_image_size = w, h = (500, 500)

for file in filelist:
    img = Image.open(file)
    width, height = img.size

    frame_num = 1
    for col_i in range(0, width, w):
        for row_i in range(0, height, h):
            crop = img.crop((col_i, row_i, col_i + w, row_i + h))
            name = os.path.basename(file)
            name = os.path.splitext(name)[0]
            save_to= os.path.join(savedir, name+"_{:03}.png")
            crop.save(save_to.format(frame_num))
            frame_num += 1

This is mostly based on DataScienceGuy answer here

In fact the "[" square opening bracket is just an internal shell alias for the test command.

So you can say:

test -f "/bin/bash" && echo "This system has a bash shell"

or

[ -f "/bin/bash" ] && echo "This system has a bash shell"

... they are equivalent in either sh or bash. Note the requirement to have a closing "]" bracket on the "[" command but other than that "[" is the same as "test". "man test" is a good thing to read.

Pattern p = Pattern.compile("tom"); //the regular-expression pattern
Matcher m = p.matcher("(bob)(tom)(harry)"); //The data to find matches with

while (m.find()) {
    //do something???
}   

Use regex to find a match maybe?

Or create an array

 String[] a = new String[]{
        "tom",
        "bob",
        "harry"
 };

 if(a.contains(stringtomatch)){
     //do something
 }

Use javax.servlet.http.HttpServletResponse class

Example:

javax.servlet.http.HttpServletResponse.SC_UNAUTHORIZED //401
javax.servlet.http.HttpServletResponse.SC_INTERNAL_SERVER_ERROR //500

Without using itertools:

def combine(inp):
    return combine_helper(inp, [], [])


def combine_helper(inp, temp, ans):
    for i in range(len(inp)):
        current = inp[i]
        remaining = inp[i + 1:]
        temp.append(current)
        ans.append(tuple(temp))
        combine_helper(remaining, temp, ans)
        temp.pop()
    return ans


print(combine(['a', 'b', 'c', 'd']))

THE ANSWER: The problem was all of the posts for such an issue were related to older kerberos and IIS issues where proxy credentials or AllowNTLM properties were helping. My case was different. What I have discovered after hours of picking worms from the ground was that somewhat IIS installation did not include Negotiate provider under IIS Windows authentication providers list. So I had to add it and move up. My WCF service started to authenticate as expected. Here is the screenshot how it should look if you are using Windows authentication with Anonymous auth OFF.

You need to right click on Windows authentication and choose providers menu item.

Hope this helps to save some time.

Add them to the allowed characters, but you'll need to escape some of them, such as -]/\

var pattern = /^[a-zA-Z0-9!@#$%^&*()_+\-=\[\]{};':"\\|,.<>\/?]*$/

That way you can remove any individual character you want to disallow.

Also, you want to include the start and end of string placemarkers ^ and $

Update:

As elclanrs understood (and the rest of us didn't, initially), the only special characters needing to be allowed in the pattern are &-._

/^[\w&.\-]+$/

[\w] is the same as [a-zA-Z0-9_]

Though the dash doesn't need escaping when it's at the start or end of the list, I prefer to do it in case other characters are added. Additionally, the + means you need at least one of the listed characters. If zero is ok (ie an empty value), then replace it with a * instead:

/^[\w&.\-]*$/

If you run "dir c:\", the last line will give you the free disk space.

Edit: Better solution: "fsutil volume diskfree c:"

Suppose your table-size (or the number for modulo) is T = (B*C). Now if hash for your input is like (N*A*B) where N can be any integer, then your output won't be well distributed. Because every time n becomes C, 2C, 3C etc., your output will start repeating. i.e. your output will be distributed only in C positions. Note that C here is (T / HCF(table-size, hash)).

This problem can be eliminated by making HCF 1. Prime numbers are very good for that.

Another interesting thing is when T is 2^N. These will give output exactly same as all the lower N bits of input-hash. As every number can be represented powers of 2, when we will take modulo of any number with T, we will subtract all powers of 2 form number, which are >= N, hence always giving off number of specific pattern, dependent on the input. This is also a bad choice.

Similarly, T as 10^N is bad as well because of similar reasons (pattern in decimal notation of numbers instead of binary).

So, prime numbers tend to give a better distributed results, hence are good choice for table size.

I just simply make changes on config.inc.php file. There is password in error in this link $cfg['Servers'][$i]['password'] = 'your password '; and now its perfectly worked .

In case you want to create your own Test Class. In Eclipse go to File -> New -> J Unit Test Case. You can then choose all your paths and testing class setup within the wizard pop-up.

Note that both pcolor and "surf + view(2)" do not show the last row and the last column of your 2D data.

On the other hand, using imagesc, you have to be careful with the axes. The surf and the imagesc examples in gevang's answer only (almost -- apart from the last row and column) correspond to each other because the 2D sinc function is symmetric.

To illustrate these 2 points, I produced the figure below with the following code:

[x, y] = meshgrid(1:10,1:5);
z      = x.^3 + y.^3;

subplot(3,1,1)
imagesc(flipud(z)), axis equal tight, colorbar
set(gca, 'YTick', 1:5, 'YTickLabel', 5:-1:1);
title('imagesc')

subplot(3,1,2)
surf(x,y,z,'EdgeColor','None'), view(2), axis equal tight, colorbar
title('surf with view(2)')

subplot(3,1,3)
imagesc(flipud(z)), axis equal tight, colorbar
axis([0.5 9.5 1.5 5.5])
set(gca, 'YTick', 1:5, 'YTickLabel', 5:-1:1);
title('imagesc cropped')

colormap jet

As you can see the 10th row and 5th column are missing in the surf plot. (You can also see this in images in the other answers.)

Note how you can use the "set(gca, 'YTick'..." (and Xtick) command to set the x and y tick labels properly if x and y are not 1:1:N.

Also note that imagesc only makes sense if your z data correspond to xs and ys are (each) equally spaced. If not you can use surf (and possibly duplicate the last column and row and one more "(end,end)" value -- although that's a kind of a dirty approach).

It looks like you just want:

eventCustom.DateTimeEnd = string.IsNullOrWhiteSpace(dateTimeEnd)
    ? (DateTime?) null
    : DateTime.Parse(dateTimeEnd);

Note that this will throw an exception if dateTimeEnd isn't a valid date.

An alternative would be:

DateTime validValue;
eventCustom.DateTimeEnd = DateTime.TryParse(dateTimeEnd, out validValue)
    ? validValue
    : (DateTime?) null;

That will now set the result to null if dateTimeEnd isn't valid. Note that TryParse handles null as an input with no problems.

A nice WebKit-only solution that takes advantage of the background-clip: text support: http://jsfiddle.net/sandro_paganotti/wLkVt/

span{
   font-size: 100px;
   background: linear-gradient(to right, black, black 50%, grey 50%, grey);
   -webkit-background-clip: text;
   -webkit-text-fill-color: transparent;
}

If you have some changes on your workspace and you want to stash them into a new branch use this command:

git stash branch branchName

It will make:

1. a new branch
2. move changes to this branch
3. and remove latest stash (Like: git stash pop)

Try these to clarify the issue of right alignment in float point printing

printf(" 4|%4.1lf\n", 8.9);
printf("04|%04.1lf\n", 8.9);

the output is

 4| 8.9
04|08.9

Use this query to get values

SELECT * FROM `buy` group by date order by date DESC

I had quite a bit of trouble as I didn't want to FIX the overlay in place as I wanted the info inside the overlay to be scrollable over the text. I used:

<html style="height=100%">
   <body style="position:relative">
      <div id="my-awesome-overlay" 
           style="position:absolute; 
                  height:100%; 
                  width:100%; 
                  display: block">
           [epic content here]
      </div>
   </body>
</html>

Of course the div in the middle needs some content and probably a transparent grey background but I'm sure you get the gist!

LL(1) grammar is Context free unambiguous grammar which can be parsed by LL(1) parsers.

In LL(1)

• First L stands for scanning input from Left to Right. Second L stands for Left Most Derivation. 1 stands for using one input symbol at each step.

For Checking grammar is LL(1) you can draw predictive parsing table. And if you find any multiple entries in table then you can say grammar is not LL(1).

Their is also short cut to check if the grammar is LL(1) or not . Shortcut Technique

To change the stacking order for series in charts under Excel for Mac 2011:

1. select the chart,
2. select the series (easiest under Ribbon>Chart Layout>Current Selection),
3. click Chart Layout>Format Selection or Menu>Format>Data Series …,
4. on popup menu Format Data Series click Order, then click individual series and click Move Up or Move Down buttons to adjust the stacking order on the Axis for the subject series. This changes the order for the plot and for the legend, but may not change the order number in the Series formula.

I had a three series plot on the secondary axis, and the series I wanted on top was stuck on the bottom in defiance of the Move Up and Move Down buttons. It happened to be formatted as markers only. I inserted a line, and presto(!), I could change its order in the plot. Later I could remove the line and sometimes it could still be ordered, but sometimes not.

You can use any function, with the str.isdigit function, like this

>>> def hasNumbers(inputString):
...     return any(char.isdigit() for char in inputString)
... 
>>> hasNumbers("I own 1 dog")
True
>>> hasNumbers("I own no dog")
False

Alternatively you can use a Regular Expression, like this

>>> import re
>>> def hasNumbers(inputString):
...     return bool(re.search(r'\d', inputString))
... 
>>> hasNumbers("I own 1 dog")
True
>>> hasNumbers("I own no dog")
False

Lists are slightly faster than sets when you just want to iterate over the values.

Sets, however, are significantly faster than lists if you want to check if an item is contained within it. They can only contain unique items though.

It turns out tuples perform in almost exactly the same way as lists, except for their immutability.

Iterating

>>> def iter_test(iterable):
...     for i in iterable:
...         pass
...
>>> from timeit import timeit
>>> timeit(
...     "iter_test(iterable)",
...     setup="from __main__ import iter_test; iterable = set(range(10000))",
...     number=100000)
12.666952133178711
>>> timeit(
...     "iter_test(iterable)",
...     setup="from __main__ import iter_test; iterable = list(range(10000))",
...     number=100000)
9.917098999023438
>>> timeit(

...     number=100000)
9.865639209747314

Determine if an object is present

First of all you missed ScriptService attribute to add in webservice.

[ScriptService]

After then try following method to call webservice via JSON.

        var webAddr = "http://Domain/VBRService.asmx/callJson";
        var httpWebRequest = (HttpWebRequest)WebRequest.Create(webAddr);
        httpWebRequest.ContentType = "application/json; charset=utf-8";
        httpWebRequest.Method = "POST";            

        using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
        {
            string json = "{\"x\":\"true\"}";

            streamWriter.Write(json);
            streamWriter.Flush();
        }

        var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
        using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
        {
            var result = streamReader.ReadToEnd();
            return result;
        }

The best way is to use AJAX ( you can find a simple tutorial on this page Tizag). The reason is that any other technique you may use requires more code, it is not guaranteed to work cross browser without rework and requires you use more client memory by opening hidden pages inside frames passing urls parsing their data and closing them. AJAX is the way to go in this situation. That my two years of javascript heavy development speaking.

I suggest merging develop and master with that command

git checkout master

git merge --commit --no-ff --no-edit develop

For more information, check https://git-scm.com/docs/git-merge

As others suggested, you can serialize and deserialize the whole list at once, which is simpler and seems to comply perfectly with what you intend to do.

In that case the serialization code becomes

ObjectOutputStream oos = null;
FileOutputStream fout = null;
try{
    fout = new FileOutputStream("G:\\address.ser", true);
    oos = new ObjectOutputStream(fout);
    oos.writeObject(myClassList);
} catch (Exception ex) {
    ex.printStackTrace();
} finally {
    if(oos != null){
        oos.close();
    } 
}

And deserialization becomes (assuming that myClassList is a list and hoping you will use generics):

ObjectInputStream objectinputstream = null;
try {
    FileInputStream streamIn = new FileInputStream("G:\\address.ser");
    objectinputstream = new ObjectInputStream(streamIn);
    List<MyClass> readCase = (List<MyClass>) objectinputstream.readObject();
    recordList.add(readCase);
    System.out.println(recordList.get(i));
} catch (Exception e) {
    e.printStackTrace();
} finally {
    if(objectinputstream != null){
        objectinputstream .close();
    } 
}

You can also deserialize several objects from a file, as you intended to:

ObjectInputStream objectinputstream = null;
try {
    streamIn = new FileInputStream("G:\\address.ser");
    objectinputstream = new ObjectInputStream(streamIn);
    MyClass readCase = null;
    do {
        readCase = (MyClass) objectinputstream.readObject();
        if(readCase != null){
            recordList.add(readCase);
        } 
    } while (readCase != null)        
    System.out.println(recordList.get(i));
} catch (Exception e) {
    e.printStackTrace();
} finally {
    if(objectinputstream != null){
        objectinputstream .close();
    } 
}

Please do not forget to close stream objects in a finally clause (note: it can throw exception).

EDIT

As suggested in the comments, it should be preferable to use try with resources and the code should get quite simpler.

Here is the list serialization :

try(
    FileOutputStream fout = new FileOutputStream("G:\\address.ser", true);
    ObjectOutputStream oos = new ObjectOutputStream(fout);
){
    oos.writeObject(myClassList);
} catch (Exception ex) {
    ex.printStackTrace();
}

The detail is on the table DUAL but if your exchange this table for a dummy table this works.

mysql_connect("localhost", "root", "") or die(mysql_error()) ;
mysql_select_db("altabotanikk") or die(mysql_error()) ;

These are deprecated use the following..

 // Connects to your Database
            $link = mysqli_connect("localhost", "root", "", "");

and to insert data use the following

 $sql = "INSERT INTO  Table-Name (Column-Name)
VALUES ('$filename')" ;

I've written a simple jQuery plugin - alterClass, that does wildcard class removal. Will optionally add classes too.

$( '#foo' ).alterClass( 'foo-* bar-*', 'foobar' ) 

ACID and BASE are consistency models for RDBMS and NoSQL respectively. ACID transactions are far more pessimistic i.e. they are more worried about data safety. In the NoSQL database world, ACID transactions are less fashionable as some databases have loosened the requirements for immediate consistency, data freshness and accuracy in order to gain other benefits, like scalability and resiliency.

BASE stands for -

• Basic Availability - The database appears to work most of the time.
• Soft-state - Stores don't have to be write-consistent, nor do different replicas have to be mutually consistent all the time.
• Eventual consistency - Stores exhibit consistency at some later point (e.g., lazily at read time).

Therefore BASE relaxes consistency to allow the system to process request even in an inconsistent state.

Example: No one would mind if their tweet were inconsistent within their social network for a short period of time. It is more important to get an immediate response than to have a consistent state of users' information.

I put together a little type check utility inspired by the above correct answers:

thetypeof = function(name) {
        let obj = {};
        obj.object = 'object Object'
        obj.array = 'object Array'
        obj.string = 'object String'
        obj.boolean = 'object Boolean'
        obj.number = 'object Number'
        obj.type = Object.prototype.toString.call(name).slice(1, -1)
        obj.name = Object.prototype.toString.call(name).slice(8, -1)
        obj.is = (ofType) => {
            ofType = ofType.toLowerCase();
            return (obj.type === obj[ofType])? true: false
        }
        obj.isnt = (ofType) => {
            ofType = ofType.toLowerCase();
            return (obj.type !== obj[ofType])? true: false
        }
        obj.error = (ofType) => {
            throw new TypeError(`The type of ${name} is ${obj.name}: `
            +`it should be of type ${ofType}`)
        }
        return obj;
    };

example:

hope you are doing well. you can use my code to crop image.you just have to make a class and use this class into your XMl and java classes. Crop image. you can crop your selected image into circle and square into many of option. hope fully it will works for you.because this is totally manageable for you and you can change it according to you.

enjoy your work :)

There are known issues with IE and Opera not removing session cookies when setting the expire date to the past (which is what the jQuery cookie plugin does)

This works fine in Safari and Mozilla/FireFox.

SELECT  *
FROM    (
        SELECT  q.*, rownum rn
        FROM    (
                SELECT  *
                FROM    maps006
                ORDER BY
                        id
                ) q
        )
WHERE   rn BETWEEN 50 AND 100

Note the double nested view. ROWNUM is evaluated before ORDER BY, so it is required for correct numbering.

If you omit ORDER BY clause, you won't get consistent order.

I use a VBScript file for doing this on Windows platform, it servers me very well.

set shell = CreateObject("WScript.Shell")
shell.run"rsync -a [email protected]:/Users/Name/Projects/test ."
WScript.Sleep 100
shell.SendKeys"Your_Password"
shell.SendKeys "{ENTER}"

For finding flash memory defects, I had to write this script which shows all 1K blocks which contain differences (not only the first one as cmp -b does)

#!/bin/sh

f1=testinput.dat
f2=testoutput.dat

size=$(stat -c%s $f1)
i=0
while [ $i -lt $size ]; do
  if ! r="`cmp -n 1024 -i $i -b $f1 $f2`"; then
    printf "%8x: %s\n" $i "$r"
  fi
  i=$(expr $i + 1024)
done

Output:

   2d400: testinput.dat testoutput.dat differ: byte 3, line 1 is 200 M-^@ 240 M- 
   2dc00: testinput.dat testoutput.dat differ: byte 8, line 1 is 327 M-W 127 W
   4d000: testinput.dat testoutput.dat differ: byte 37, line 1 is 270 M-8 260 M-0
   4d400: testinput.dat testoutput.dat differ: byte 19, line 1 is  46 &  44 $

Disclaimer: I hacked the script in 5 min. It doesn't support command line arguments nor does it support spaces in file names

Also i have found another useful link. It is a background hack used like this

.selector { background-size: cover; -ms-behavior: url(/backgroundsize.min.htc); }

https://github.com/louisremi/background-size-polyfill

Using awk.

i starts at 0, i++ will increment the value of i, but return the original value that i held before being incremented.

awk '{print i++ "," $0}' file

how about:

return preg_replace("/[^a-zA-Z0-9`_.,;@#%~'\"\+\*\?\[\^\]\$\(\)\{\}\=\!\<\>\|\:\-\s\\\\]+/", "", $data);

gives me complete control of what I want to include

here is a simple javascript for that

call this when you need to scroll the screen to an element which has id="yourSpecificElementId"

window.scroll(0,findPos(document.getElementById("yourSpecificElementId")));

and you need this function for the working:

//Finds y value of given object
function findPos(obj) {
    var curtop = 0;
    if (obj.offsetParent) {
        do {
            curtop += obj.offsetTop;
        } while (obj = obj.offsetParent);
    return [curtop];
    }
}

the screen will be scrolled to your specific element.

Simplest example using the Standard Library.

#include <iostream>
using namespace std;

int main()
{
  char c = 'n';
  cout << "HEX " << hex << (int)c << endl;  // output in hexadecimal
  cout << "ASC" << c << endl; // output in ascii
  return 0;
}

To check the output, codepad returns: 6e

and an online ascii-to-hexadecimal conversion tool yields 6e as well. So it works.

You can also do this:

template<class T> std::string toHexString(const T& value, int width) {
    std::ostringstream oss;
    oss << hex;
    if (width > 0) {
        oss << setw(width) << setfill('0');
    }
    oss << value;
    return oss.str();
}

I thought of writing an updated and in depth answer here.

final keyword can be used in several places.

1. classes

A final class means that no other class can extend that final class. When Java Run Time (JRE) knows an object reference is in type of a final class (say F), it knows that the value of that reference can only be in type of F.

Ex:

F myF;
myF = new F();    //ok
myF = someOther;  //someOther cannot be in type of a child class of F.
                  //because F cannot be extended.

So when it executes any method of that object, that method doesn't need to be resolved at run time using a virtual table. i.e. run-time polymorphism cannot be applied. So the run time doesn't bother about that. Which means it saves processing time, which will improve performance.

2. methods

A final method of any class means that any child class extending that class cannot override that final method(s). So the run time behavior in this scenario is also quite same with the previous behavior I mentioned for classes.

3. fields, local variables, method parameters

If one specified any kind of above as final, it means that the value is already finalized, so the value cannot be changed.

Ex:

For fields, local parameters

final FinalClass fc = someFC; //need to assign straight away. otherwise compile error.
final FinalClass fc; //compile error, need assignment (initialization inside a constructor Ok, constructor can be called only once)
final FinalClass fc = new FinalClass(); //ok
fc = someOtherFC; //compile error
fc.someMethod(); //no problem
someOtherFC.someMethod(); //no problem

For method parameters

void someMethod(final String s){
    s = someOtherString; //compile error
}

This simply means that value of the final reference value cannot be changed. i.e. only one initialization is allowed. In this scenario, in run time, since JRE knows that values cannot be changed, it loads all these finalized values (of final references) into L1 cache. Because it doesn't need to load back again and again from main memory. Otherwise it loads to L2 cache and does time to time loading from main memory. So it is also a performance improvement.

So in all above 3 scenarios, when we have not specified the final keyword in places we can use, we don't need to worry, compiler optimizations will do that for us. There are also lots of other things that compiler optimizations do for us. :)

In 2017, JPA 2.1 still has only @Column(columnDefinition='...') to which you put the literal SQL definition of the column. Which is quite unflexible and forces you to also declare the other aspects like type, short-circuiting the JPA implementation's view on that matter.

Hibernate though, has this:

@Column(length = 4096, nullable = false)
@org.hibernate.annotations.ColumnDefault("")
private String description;

Identifies the DEFAULT value to apply to the associated column via DDL.

• Hibernate 4.3 docs (4.3 to show it's been here for quite some time)
• Hibernate manual on Default value for database column

Two notes to that:

1) Don't be afraid of going non-standard. Working as a JBoss developer, I've seen quite some specification processes. The specification is basically the baseline that the big players in given field are willing to commit to support for the next decade or so. It's true for security, for messaging, ORM is no difference (although JPA covers quite a lot). My experience as a developer is that in a complex application, sooner or later you will need a non-standard API anyway. And @ColumnDefault is an example when it outweigts the negatives of using a non-standard solution.

2) It's nice how everyone waves @PrePersist or constructor member initialization. But that's NOT the same. How about bulk SQL updates? How about statements that don't set the column? DEFAULT has it's role and that's not substitutable by initializing a Java class member.

I assume that since you're using an XML declaration, you're not worrying about IE or older browsers.

So you can use display:table-cell and display:table-row like so:

Swift 3 version

Swift 3 utilizes new DispatchQueue class to manage queues and threads. To run something on the background thread you would use:

let backgroundQueue = DispatchQueue(label: "com.app.queue", qos: .background)
backgroundQueue.async {
    print("Run on background thread")
}

Or if you want something in two lines of code:

DispatchQueue.global(qos: .background).async {
    print("Run on background thread")

    DispatchQueue.main.async {
        print("We finished that.")
        // only back on the main thread, may you access UI:
        label.text = "Done."
    }
}

You can also get some in-depth info about GDC in Swift 3 in this tutorial.

I wrote my own export to Excel writer because nothing else quite met my needs. It is fast and allows for substantial formatting of the cells. You can review it at

I hope it helps.

Requests 2.6 introduced this warning for users of python prior to 2.7.9 with only stock SSL modules available.

Assuming you can't upgrade to a newer version of python, this will install more up-to-date python SSL libraries:

pip install --upgrade ndg-httpsclient 

HOWEVER, this may fail on some systems without the build-dependencies for pyOpenSSL. On debian systems, running this before the pip command above should be enough for pyOpenSSL to build:

apt-get install python-dev libffi-dev libssl-dev

You cannot return value after resolving promise. Instead call another function when promise is resolved:

function justTesting() {
    promise.then(function(output) {
        // instead of return call another function
        afterResolve(output + 1);
    });
}

function afterResolve(result) {
    // do something with result
}

var test = justTesting();

Once focus of edit text is removed, it would not allow you to type even if you set it to focusable again.

Here is a way around it

if (someCondition)
   editTextField.setFocusable(false);
else
   editTextField.setFocusableInTouchMode(true);

Setting it true in setFocusableInTouchMode() seems to do the trick.

A solution I tend to use more and more is this one:

import matplotlib.pyplot as plt

fig, axs = plt.subplots(2, 2)  # 1
for i, ax in enumerate(axs.ravel()): # 2
    ax.set_title("Plot #{}".format(i)) # 3

1. Create your arbitrary number of axes
2. axs.ravel() converts your 2-dim object to a 1-dim vector in row-major style
3. assigns the title to the current axis-object

it should work using - (void)scrollToRowAtIndexPath:(NSIndexPath *)indexPath atScrollPosition:(UITableViewScrollPosition)scrollPosition animated:(BOOL)animated using it this way:

NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
[yourTableView scrollToRowAtIndexPath:indexPath 
                     atScrollPosition:UITableViewScrollPositionTop 
                             animated:YES];

atScrollPosition could take any of these values:

typedef enum {
UITableViewScrollPositionNone,
UITableViewScrollPositionTop,
UITableViewScrollPositionMiddle,
UITableViewScrollPositionBottom
} UITableViewScrollPosition;

I hope this helps you

I just wrote a directive to handle this, so you can simply add the attribute bs-active-link to the parent <ul> element, and any time the route changed, it will find the matching link, and add the active class to the corresponding <li>.

You can see it in action here: http://jsfiddle.net/8mcedv3b/

Example HTML:

<ul class="nav navbar-nav" bs-active-link>
  <li><a href="/home">Home</a></li>
  <li><a href="/contact">Contact</a></li>
</ul>

Javascript:

angular.module('appName')
.directive('bsActiveLink', ['$location', function ($location) {
return {
    restrict: 'A', //use as attribute 
    replace: false,
    link: function (scope, elem) {
        //after the route has changed
        scope.$on("$routeChangeSuccess", function () {
            var hrefs = ['/#' + $location.path(),
                         '#' + $location.path(), //html5: false
                         $location.path()]; //html5: true
            angular.forEach(elem.find('a'), function (a) {
                a = angular.element(a);
                if (-1 !== hrefs.indexOf(a.attr('href'))) {
                    a.parent().addClass('active');
                } else {
                    a.parent().removeClass('active');   
                };
            });     
        });
    }
}
}]);

- Another Update -

Since Twitter Bootstrap version 2.0 - which saw the removal of the .container-fluid class - it has not been possible to implement a two column fixed-fluid layout using just the bootstrap classes - however I have updated my answer to include some small CSS changes that can be made in your own CSS code that will make this possible

It is possible to implement a fixed-fluid structure using the CSS found below and slightly modified HTML code taken from the Twitter Bootstrap Scaffolding : layouts documentation page:

HTML

<div class="container-fluid fill">
    <div class="row-fluid">
        <div class="fixed">  <!-- we want this div to be fixed width -->
            ...
        </div>
        <div class="hero-unit filler">  <!-- we have removed spanX class -->
            ...
        </div>
    </div>
</div>

CSS

/* CSS for fixed-fluid layout */

.fixed {
    width: 150px;  /* the fixed width required */
    float: left;
}

.fixed + div {
     margin-left: 150px;  /* must match the fixed width in the .fixed class */
     overflow: hidden;
}


/* CSS to ensure sidebar and content are same height (optional) */

html, body {
    height: 100%;
}

.fill { 
    min-height: 100%;
    position: relative;
}

.filler:after{
    background-color:inherit;
    bottom: 0;
    content: "";
    height: auto;
    min-height: 100%;
    left: 0;
    margin:inherit;
    right: 0;
    position: absolute;
    top: 0;
    width: inherit;
    z-index: -1;  
}

I have kept the answer below - even though the edit to support 2.0 made it a fluid-fluid solution - as it explains the concepts behind making the sidebar and content the same height (a significant part of the askers question as identified in the comments)

Important

Answer below is fluid-fluid

Update As pointed out by @JasonCapriotti in the comments, the original answer to this question (created for v1.0) did not work in Bootstrap 2.0. For this reason, I have updated the answer to support Bootstrap 2.0

To ensure that the main content fills at least 100% of the screen height, we need to set the height of the html and body to 100% and create a new css class called .fill which has a minimum-height of 100%:

html, body {
    height: 100%;
}

.fill { 
    min-height: 100%;
}

We can then add the .fill class to any element that we need to take up 100% of the sceen height. In this case we add it to the first div:

<div class="container-fluid fill">
    ...
</div>

To ensure that the Sidebar and the Content columns have the same height is very difficult and unnecessary. Instead we can use the ::after pseudo selector to add a filler element that will give the illusion that the two columns have the same height:

.filler::after {
    background-color: inherit;
    bottom: 0;
    content: "";
    right: 0;
    position: absolute;
    top: 0;
    width: inherit;
    z-index: -1;  
}

To make sure that the .filler element is positioned relatively to the .fill element we need to add position: relative to .fill:

.fill { 
    min-height: 100%;
    position: relative;
}

And finally add the .filler style to the HTML:

HTML

<div class="container-fluid fill">
    <div class="row-fluid">
        <div class="span3">
            ...
        </div>
        <div class="span9 hero-unit filler">
            ...
        </div>
    </div>
</div>

Notes

• If you need the element on the left of the page to be the filler then you need to change right: 0 to left: 0.

I'm working with RecyclerView and both the remove and the update work well.

1) REMOVE: There are 4 steps to remove an item from a RecyclerView

list.remove(position);
recycler.removeViewAt(position);
mAdapter.notifyItemRemoved(position);                 
mAdapter.notifyItemRangeChanged(position, list.size());

These line of codes work for me.

2) UPDATE THE DATA: The only things I had to do is

mAdapter.notifyDataSetChanged();

You had to do all of this in the Actvity/Fragment code not in the RecyclerView Adapter code.

Here is an example of an AWK I used a while ago. It is an AWK that prints new AWKS. AWK and SED being similar it may be a good template.

ls | awk '{ print "awk " "'"'"'"  " {print $1,$2,$3} " "'"'"'"  " " $1 ".old_ext > " $1 ".new_ext"  }' > for_the_birds

It looks excessive, but somehow that combination of quotes works to keep the ' printed as literals. Then if I remember correctly the vaiables are just surrounded with quotes like this: "$1". Try it, let me know how it works with SED.

tl;dr

Use either of the Map implementations bundled with Java 6 and later that implement NavigableMap (the successor to SortedMap):

• Use TreeMap if running single-threaded, or if the map is to be read-only across threads after first being populated.
• Use ConcurrentSkipListMap if manipulating the map across threads.

NavigableMap

FYI, the SortedMap interface was succeeded by the NavigableMap interface.

You would only need to use SortedMap if using 3rd-party implementations that have not yet declared their support of NavigableMap. Of the maps bundled with Java, both of the implementations that implement SortedMap also implement NavigableMap.

Interface versus concrete class

s SortedMap the best answer? TreeMap?

As others mentioned, SortedMap is an interface while TreeMap is one of multiple implementations of that interface (and of the more recent NavigableMap.

Having an interface allows you to write code that uses the map without breaking if you later decide to switch between implementations.

NavigableMap< Employee , Project > currentAssignments = new TreeSet<>() ;
currentAssignments.put( alice , writeAdCopyProject ) ; 
currentAssignments.put( bob , setUpNewVendorsProject ) ; 

This code still works if later change implementations. Perhaps you later need a map that supports concurrency for use across threads. Change that declaration to:

NavigableMap< Employee , Project > currentAssignments = new ConcurrentSkipListMap<>() ;

…and the rest of your code using that map continues to work.

Choosing implementation

There are ten implementations of Map bundled with Java 11. And more implementations provided by 3rd parties such as Google Guava.

Here is a graphic table I made highlighting the various features of each. Notice that two of the bundled implementations keep the keys in sorted order by examining the key’s content. Also, EnumMap keeps its keys in the order of the objects defined on that enum. Lastly, the LinkedHashMap remembers original insertion order.

As suggested in this answer to a related question, "edge" mode can be set in the Web.Config file. This will make it apply to all HTML returned from the application without the need to insert it into individual pages:

<configuration>
    <system.webServer>
        <httpProtocol>
            <customHeaders>
                <add name="X-UA-Compatible" value="IE=edge" />
            </customHeaders>
        </httpProtocol>
    </system.webServer>
</configuration>

This same step can also be accomplished by modifying the "HTTP Response Headers" using IIS Manager for the IIS server, entire website, or specific applications.

Open access, go to the database tools tab, select compact and repair database. You can choose the database from there.

First off, this is one of those things that slaps me in the face with surprise: renaming of a column requires creating an entirely new table and copying the data from the old table to the new table...

The GUI I've landed on to do SQLite operations is Base. It's got a nifty Log window that shows all the commands that have been executed. Doing a rename of a column via Base populates the log window with the necessary commands:

These can then be easily copied and pasted where you might need them. For me, that's into an ActiveAndroid migration file. A nice touch, as well, is that the copied data only includes the SQLite commands, not the timestamps, etc.

Hopefully, that saves some people time.

If you’re at the MySQL command line mysql> you have to declare the SQL file as source.

mysql> source \home\user\Desktop\test.sql;

Just try Clean Project & Rebuild Project.

For some reason none of the above fixes worked for me (I had the same problem), but this did:

Try putting all of the floated elements in a div element: <div class="row">...</div>.

Then add this CCS: .row::after {content: ""; clear: both; display: table;}

For manually resetting the password in Wordpress DB, a simple MD5 hash is sufficient. (see reason below)

To prevent breaking backwards compatibility, MD5-hashed passwords stored in the database are still valid. When a user logs in with such a password, WordPress detects MD5 was used, rehashes the password using the more secure method, and stores the new hash in the database.

Update: this was an answer posted in 2014. I don't know if it still works for the latest version of WP since I don't work with WP anymore.

The above error can be as a result of wrongly named input variables from the view form, which resorts to seeking a default value since no variable is supplied hence-- SQLSTATE[HY000]: General error: 1364 Field 'user_id' doesn't have a default value (SQL: insert into posts (updated_at, created_at) values (2017-04-27 10:29:59, 2017-04-27 10:29:59))

The following worked well for me

try {
    asdf
} catch {
    $string_err = $_ | Out-String
}

write-host $string_err

The result of this is the following as a string instead of an ErrorRecord object

asdf : The term 'asdf' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

A "REST service" and a "RESTful service" are one and the same.

A RESTful system is any system that follows the REST conventions as defined in the original document that created the idea of RESTful networked applications.

It's worth noting there are varying levels of RESTfulness. Overall, REST is a style, not a standard, so there is room for interpretation based on needs. one example is hierarchical resource URLs (e.g. /things/ID/relatedthings) vs flat URLs (e.g. /things/ID and /relatedthings?thing=ID)

All you need is width:100% somewhere that applies to the tag as shown by the various answers here.

Using col-xs-12:

<!-- adds float:left, which is usually not a problem -->
<img class='img-responsive col-xs-12' />

Or inline CSS:

<img class='img-responsive' style='width:100%;' />

Or, in your own CSS file, add an additional definition for .img-responsive

.img-responsive { 
    width:100%;
}

THE ROOT OF THE PROBLEM

This is a known FF bug that <fieldset> does not respect overflow rules:

https://bugzilla.mozilla.org/show_bug.cgi?id=261037

A CSS "FIX" to fix the FireFox bug would be to make the <fieldset> display:table-column. However, doing so, according to the following link, will cause the display of the fieldset to fail in Opera:

https://github.com/TryGhost/Ghost/issues/789

So, just set your tag to 100% width as described in one of the solutions above.

To get the number of days the easiest way would be:

SELECT EXTRACT(DAY FROM NOW() - '2014-08-02 08:10:56');

As far as I know it would return the same as:

SELECT (EXTRACT(epoch FROM (SELECT (NOW() - '2014-08-02 08:10:56')))/86400)::int;

function logout() {
  var userAgent = navigator.userAgent.toLowerCase();

I had the same problem with eclipse on windows 10.

I installed it like recommende over the windows command window (cmd) with:

C:\Users\NAMEOFUSER\AppData\Local\Programs\Python\beautifulsoup4-4.8.2\setup.py install 

BeautifulSoup was install like this in my python directory:

C:\Users\NAMEOFUSE\AppData\Local\Programs\Python\Python38\Lib\site-packages\beautifulsoup4-4.8.2-py3.8.egg

After manually coping the bs4 and EGG-INFO folders into the site-packages folder everything started to work, also the example:

from bs4 import BeautifulSoup


html = """
    <html>
        <body>
            <p> Ich bin ein Absatz!</p>
        </body>
    </html>
"""
print(html)


soup = BeautifulSoup(html, 'html.parser')

print(soup.find_all("p"))

You need jQuery see bootstrap's basic template

This way works for me:

declare module 'Injector';

  {
    "compilerOptions": {
        "strictNullChecks": true,
        "moduleResolution": "node",
        "jsx": "react",

        "src/**/*",
        "index.d.ts",   // declaration file path
      ],
      "compileOnSave": false
    }

-- edit: needed quotation marks around module name

This way a token will exist up-to 24 hours. here is the code to generate token which will valid up-to 24 Hours. this code we use but i did not compose it.

public static string GenerateToken()
{
    int month = DateTime.Now.Month;
    int day = DateTime.Now.Day;
    string token = ((day * 100 + month) * 700 + day * 13).ToString();
    return token;
}

npm install installs dependencies into the node_modules/ directory, for the node project you're working on. You can call install on another node.js project (module), to install it as a dependency for your project.

npm run build does nothing unless you specify what "build" does in your package.json file. It lets you perform any necessary building/prep tasks for your project, prior to it being used in another project.

npm build is an internal command and is called by link and install commands, according to the documentation for build:

This is the plumbing command called by npm link and npm install.

You will not be calling npm build normally as it is used internally to build native C/C++ Node addons using node-gyp.

Unless you want to go the VBA route to work out the Tab name, the Excel formula is fairly ugly based upon Mid functions, etc. But both these methods can be found here if you want to go that way.

Rather, the way I would do it is:

1) Make one cell on your sheet named, for example, Reference_Sheet and put in that cell the value "Jan Item" for example.

2) Now, use the Indirect function like:

=INDIRECT(Reference_Sheet&"!J3") 

3) Now, for each month's sheet, you just have to change that one Reference_Sheet cell.

Hope this gives you what you're looking for!

String filePath = Environment.getExternalStorageDirectory()+"/yourfolderNAme/yopurfile.mp3";
mediaPlayer = new  MediaPlayer();
mediaPlayer.setDataSource(filePath);
mediaPlayer.prepare();   
mediaPlayer.start()

and this play from raw folder.

int resID = myContext.getResources().getIdentifier(playSoundName,"raw",myContext.getPackageName());

            MediaPlayer mediaPlayer = MediaPlayer.create(myContext,resID);
            mediaPlayer.prepare();
            mediaPlayer.start();

mycontext=application.this. use.

You can try with this. You have this error because we can not divide by 'zero' (0) value. So we want to validate before when we do calculations.

if ($itemCost != 0 && $itemCost != NULL && $itemQty != 0 && $itemQty != NULL) 
{
    $diffPricePercent = (($actual * 100) / $itemCost) / $itemQty;
}

And also we can validate POST data. Refer following

$itemQty = isset($_POST['num1']) ? $_POST['num1'] : 0;

$itemCost = isset($_POST['num2']) ? $_POST['num2'] : 0;

$itemSale = isset($_POST['num3']) ? $_POST['num3'] : 0;

$shipMat = isset($_POST['num4']) ? $_POST['num4'] : 0;

Yes, and it seems to have (more or less) the same API.

All these answers above are great. And the way to go on a full featured application.

But if you want to prototype fast, want flexibility as the collection still changes as well as to minimize your early code base, there is a much simpler way that is not much discussed.

You can basically forego mongoimport by now. I could have saved 3 hours if it was mentioned here on this question. So let me share for others:

Mongodb has a GUI called Mongo Compass has both csv and json import features out of the box in a matter of clicks. It is an official part of the Mongo ecosytem. At the time of writing it is free and it works very well for my use case. https://www.mongodb.com/products/compass

1. You simply get MongoDB compass running on your machine by following the simple installation. A couple of fields for DB connection and authentication directly in the GUI.
2. Import the csv/json file. It took less than a second on a 30KB file to be parsed before user (me) validates.
3. Validate the "type" of each property. Great feature, I could directly mention the property types such as booleans, integers, etc. In my experience, they seem all default to string. You can update before importing. Dates were more finicky and needed special attention on the coding side.
4. One click further the csv is a collection in your mongo db local or on the cloud. Voila!

In this case you might want to use the functions np.hstack and np.vstack

arr = np.array([])
arr = np.hstack((arr, np.array([1,2,3])))
# arr is now [1,2,3]

arr = np.vstack((arr, np.array([4,5,6])))
# arr is now [[1,2,3],[4,5,6]]

You also can use the np.concatenate function.

If you want to just toggle visibility and still keep the input in DOM:

<input class="txt" type="password" [(ngModel)]="input_pw" 
 [style.visibility]="isHidden? 'hidden': 'visible'">

The other way around is as per answer by rrd, which is to use HTML hidden attribute. In an HTML element if hidden attribute is set to true browsers are supposed to hide the element from display, but the problem is that this behavior is overridden if the element has an explicit display style mentioned.

.hasDisplay {_x000D_
  display: block;_x000D_
}

<input class="hasDisplay" hidden value="shown" />_x000D_
<input hidden value="not shown">

To overcome this you can opt to use an explicit css for [hidden] that overrides the display;

[hidden] {
  display: none !important;
}

Yet another way is to have a is-hidden class and do:

<input [class.is-hidden]="isHidden"/>

.is-hidden {
      display: none;
 }

If you use display: none the element will be skipped from the static flow and no space will be allocated for the element, if you use visibility: hidden it will be included in the flow and a space will be allocated but it will be blank space.

The important thing is to use one way across an application rather than mixing different ways thereby making the code less maintainable.

If you want to remove it from DOM

<input class="txt" type="password" [(ngModel)]="input_pw" *ngIf="!isHidden">

It is unfortunately not supported in older versions of MSTest. Apparently there is an extensibility model and you can implement it yourself. Another option would be to use data-driven tests.

My personal opinion would be to just stick with NUnit though...

As of Visual Studio 2012, update 1, MSTest has a similar feature. See McAden's answer.

For others facing a similar problem to mine, where you know a particular object property cannot be null, you can use the non-null assertion operator (!) after the item in question. This was my code:

  const naciStatus = dataToSend.naci?.statusNACI;
  if (typeof naciStatus != "undefined") {
    switch (naciStatus) {
      case "AP":
        dataToSend.naci.certificateStatus = "FALSE";
        break;
      case "AS":
      case "WR":
        dataToSend.naci.certificateStatus = "TRUE";
        break;
      default:
        dataToSend.naci.certificateStatus = "";
    }
  }

And because dataToSend.naci cannot be undefined in the switch statement, the code can be updated to include exclamation marks as follows:

  const naciStatus = dataToSend.naci?.statusNACI;
  if (typeof naciStatus != "undefined") {
    switch (naciStatus) {
      case "AP":
        dataToSend.naci!.certificateStatus = "FALSE";
        break;
      case "AS":
      case "WR":
        dataToSend.naci!.certificateStatus = "TRUE";
        break;
      default:
        dataToSend.naci!.certificateStatus = "";
    }
  }

If you need a body in your response, you can call

return StatusCode(StatusCodes.Status500InternalServerError, responseObject);

This will return a 500 with the response object...

I had a case with 3 levels a'la _MainLayout.cshtml <--- _Middle.cshtml <--- Page.cshtml. Even though doing like this:

_MainLayout.cshtml

<head>
   @RenderSection("head", false)
</head>

_Middle.cshtml

@section head {
    @RenderSection("head")
}

and in Page.cshtml defining

@section head {
   ***content***
}

I would still get the error

The following sections have been defined but have not been rendered for the layout page “~/Views/Shared/_Middle.cshtml”: "head".

Turned out, the error was for the Middle.cshtml to rely on /Views/_ViewStart.cshtml to resolve it's parent layout. The problem was resolved by defining this in Middle.cshtml explicitly:

@{
Layout = "~/Views/_Shared/_MainLayout.cshtml";
}

Can't decide whether this would be by-design or a bug in MVC 4 - anyhow, problem was solved :)

Column names must be unique in the table. You cannot have two columns named asd in the same table.

UPDATE: 30.07.2014

If you use Android Studio, make sure you have at least 144x144 resource and than use "FILE-NEW-IMAGE ASSET". Android Studio will make proper image files to all folders for you : )

As documentation says, adjust bitmaps as follows:

Almost every application should have alternative drawable resources for different screen densities, because almost every application has a launcher icon and that icon should look good on all screen densities. Likewise, if you include other bitmap drawables in your application (such as for menu icons or other graphics in your application), you should provide alternative versions or each one, for different densities.

Note: You only need to provide density-specific drawables for bitmap files (.png, .jpg, or .gif) and Nine-Path files (.9.png). If you use XML files to define shapes, colors, or other drawable resources, you should put one copy in the default drawable directory (drawable/).

To create alternative bitmap drawables for different densities, you should follow the 3:4:6:8 scaling ratio between the four generalized densities. For example, if you have a bitmap drawable that's 48x48 pixels for medium-density screen (the size for a launcher icon), all the different sizes should be:

36x36 for low-density (LDPI)

48x48 for medium-density (MDPI)

72x72 for high-density (HDPI)

96x96 for extra high-density (XHDPI)

144x144 for extra extra high-density (XXHDPI)

192x192 for extra extra extra high-density (XXXHDPI)

As string[] implements IEnumerable

IEnumerable<string> m_oEnum = new string[] {"1","2","3"}

This is portable - at least between ORACLE and PostgreSQL:

select t.* from table t 
where not exists(select 1 from table ti where ti.attr > t.attr);

If you're using display:table-row etc., then you need proper markup, which includes a containing table. Without it your original question basically provides the equivalent bad markup of:

<tr style="width:100%">
    <td>Type</td>
    <td style="float:right">Name</td>
</tr>

Where's the table in the above? You can't just have a row out of nowhere (tr must be contained in either table, thead, tbody, etc.)

Instead, add an outer element with display:table, put the 100% width on the containing element. The two inside cells will automatically go 50/50 and align the text right on the second cell. Forget floats with table elements. It'll cause so many headaches.

markup:

<div class="view-table">
    <div class="view-row">
        <div class="view-type">Type</div>
        <div class="view-name">Name</div>                
    </div>
</div>

CSS:

.view-table
{
    display:table;
    width:100%;
}
.view-row,
{
    display:table-row;
}
.view-row > div
{
    display: table-cell;
}
.view-name 
{
    text-align:right;
}

You can embed HTML in Markdown, so you can do something like this:

<img style="float: right;" src="whatever.jpg">

Continue markdown text...

I built my solution on top of @aditya Prakash appraoch:

 print(re.search("^([1-9]|0[1-9]|1[0-9]|2[0-9]|3[0-1])(\.|-|/)([1-9]|0[1-9]|1[0-2])(\.|-|/)([0-9][0-9]|19[0-9][0-9]|20[0-9][0-9])$|^([0-9][0-9]|19[0-9][0-9]|20[0-9][0-9])(\.|-|/)([1-9]|0[1-9]|1[0-2])(\.|-|/)([1-9]|0[1-9]|1[0-9]|2[0-9]|3[0-1])$",'01/01/2018'))

The first part (^([1-9]|0[1-9]|1[0-9]|2[0-9]|3[0-1])(\.|-|/)([1-9]|0[1-9]|1[0-2])(\.|-|/)([0-9][0-9]|19[0-9][0-9]|20[0-9][0-9])$) can handle the following formats:

• 01.10.2019
• 1.1.2019
• 1.1.19
• 12/03/2020
• 01.05.1950

The second part (^([0-9][0-9]|19[0-9][0-9]|20[0-9][0-9])(\.|-|/)([1-9]|0[1-9]|1[0-2])(\.|-|/)([1-9]|0[1-9]|1[0-9]|2[0-9]|3[0-1])$) can basically do the same, but in inverse order, where the year comes first, followed by month, and then day.

• 2020/02/12

As delimiters it allows ., /, -. As years it allows everything from 1900-2099, also giving only two numbers is fine.

If you have suggestions for improvement please let me know in the comments, so I can update the answer.

You can simply use:

diff -y fileA.txt fileB.txt | colordiff

It shows the output splitted in two colums and colorized! (colordiff)

When you do return Json(...) you are specifically telling MVC not to use a view, and to serve serialized JSON data. Your browser opens a download dialog because it doesn't know what to do with this data.

If you instead want to return a view, just do return View(...) like you normally would:

var dictionary = listLocation.ToDictionary(x => x.label, x => x.value);
return View(new { Values = listLocation });

Then in your view, simply encode your data as JSON and assign it to a JavaScript variable:

<script>
    var values = @Html.Raw(Json.Encode(Model.Values));
</script>

EDIT

Here is a bit more complete sample. Since I don't have enough context from you, this sample will assume a controller Foo, an action Bar, and a view model FooBarModel. Additionally, the list of locations is hardcoded:

Controllers/FooController.cs

public class FooController : Controller
{
    public ActionResult Bar()
    {
        var locations = new[]
        {
            new SelectListItem { Value = "US", Text = "United States" },
            new SelectListItem { Value = "CA", Text = "Canada" },
            new SelectListItem { Value = "MX", Text = "Mexico" },
        };

        var model = new FooBarModel
        {
            Locations = locations,
        };

        return View(model);
    }
}

Models/FooBarModel.cs

public class FooBarModel
{
    public IEnumerable<SelectListItem> Locations { get; set; }
}

Views/Foo/Bar.cshtml

@model MyApp.Models.FooBarModel

<script>
    var locations = @Html.Raw(Json.Encode(Model.Locations));
</script>

By the looks of your error message, it seems like you are mixing incompatible types (i.e. Ported_LI.Models.Locatio??n and MyApp.Models.Location) so, to recap, make sure the type sent from the controller action side match what is received from the view. For this sample in particular, new FooBarModel in the controller matches @model MyApp.Models.FooBarModel in the view.

System.out.println("\"Hello\""); 

If you are trying to load the image at your form_load, it's a better idea to use the code

pictureBox1.LoadAsync(@"http://google.com/test.png");

not only loading from web but also no lag in your form loading.

This is the first working version of what will be a GPS reader and data presenter. tkinter is a very fragile thing with way too few error messages. It does not put stuff up and does not tell why much of the time. Very difficult coming from a good WYSIWYG form developer. Anyway, this runs a small routine 10 times a second and presents the information on a form. Took a while to make it happen. When I tried a timer value of 0, the form never came up. My head now hurts! 10 or more times per second is good enough for me. I hope it helps someone else. Mike Morrow

I personally do it this way, keeping the embedded CASE expressions confined. I'd also put comments in to explain what is going on. If it is too complex, break it out into function.

SELECT
    col1,
    col2,
    col3,
    CASE WHEN condition THEN
      CASE WHEN condition1 THEN
        CASE WHEN condition2 THEN calculation1
        ELSE calculation2 END
      ELSE
        CASE WHEN condition2 THEN calculation3
        ELSE calculation4 END
      END
    ELSE CASE WHEN condition1 THEN 
      CASE WHEN condition2 THEN calculation5
      ELSE calculation6 END
    ELSE CASE WHEN condition2 THEN calculation7
         ELSE calculation8 END
    END AS 'calculatedcol1',
    col4,
    col5 -- etc

Remember, you are NOT allowed to do this.

class foo():
    def print_hello(self):
        print("Hello")       # This next line will produce an ERROR!
    self.print_hello()       # <---- it calls a class function, inside a class,
                             # but outside a class function. Not allowed.

You must call a class function from either outside the class, or from within a function in that class.

At least for pip 1.3.1, it honors the http_proxy and https_proxy environment variables. Make sure you define both, as it will access the PYPI index using https.

export https_proxy="http://<proxy.server>:<port>"
pip install TwitterApi

Using param to name the parameters allows you to ignore the order of the parameters:

ParamEx.ps1

# Show how to handle command line parameters in Windows PowerShell
param(
  [string]$FileName,
  [string]$Bogus
)
write-output 'This is param FileName:'+$FileName
write-output 'This is param Bogus:'+$Bogus

ParaEx.bat

rem Notice that named params mean the order of params can be ignored
powershell -File .\ParamEx.ps1 -Bogus FooBar -FileName "c:\windows\notepad.exe"

You're right that the SD Card directory is /sdcard but you shouldn't be hard coding it. Instead, make a call to Environment.getExternalStorageDirectory() to get the directory:

File sdDir = Environment.getExternalStorageDirectory();

If you haven't done so already, you will need to give your app the correct permission to write to the SD Card by adding the line below to your Manifest:

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

Take a look at the sqlcmd utility. It allows you to execute SQL from the command line.

http://msdn.microsoft.com/en-us/library/ms162773.aspx

It's all in there in the documentation, but the syntax should look something like this:

sqlcmd -U myLogin -P myPassword -S MyServerName -d MyDatabaseName 
    -Q "DROP TABLE MyTable"

It looks like get-pip.py has been updated to use the environment variables http_proxy and https_proxy.

Windows:

set http_proxy=http://proxy.myproxy.com
set https_proxy=https://proxy.myproxy.com
python get-pip.py

Linux/OS X:

export http_proxy=http://proxy.myproxy.com
export https_proxy=https://proxy.myproxy.com
sudo -E python get-pip.py

However if this still doesn't work for you, you can always install pip through a proxy using setuptools' easy_install by setting the same environment variables.

Windows:

set http_proxy=http://proxy.myproxy.com
set https_proxy=https://proxy.myproxy.com
easy_install pip

Linux/OS X:

export http_proxy=http://proxy.myproxy.com
export https_proxy=https://proxy.myproxy.com
sudo -E easy_install pip

Then once it's installed, use:

pip install --proxy="user:password@server:port" packagename

From the pip man page:

--proxy
Have pip use a proxy server to access sites. This can be specified using "user:[email protected]:port" notation. If the password is left out, pip will ask for it.

The code you provided would print the number of tabs, not the number of spaces. The below function should count the number of whitespace characters in a given string.

int countSpaces(String string) {
    int spaces = 0;
    for(int i = 0; i < string.length(); i++) {
        spaces += (Character.isWhitespace(string.charAt(i))) ? 1 : 0;
    }
    return spaces;
}

If you're working with new versions of Django (>10) and don't want to spend time writing the model definition. you can use the ogrinspect tool.

This will create a code definition for the model .

python manage.py ogrinspect [/path/to/thecsv] Product

The output will be the class (model) definition. In this case the model will be called Product. You need to copy this code into your models.py file.

Afterwards you need to migrate (in the shell) the new Product table with:

python manage.py makemigrations
python manage.py migrate

More information here: https://docs.djangoproject.com/en/1.11/ref/contrib/gis/tutorial/

Do note that the example has been done for ESRI Shapefiles but it works pretty good with standard CSV files as well.

For ingesting your data (in CSV format) you can use pandas.

import pandas as pd
your_dataframe = pd.read_csv(path_to_csv)
# Make a row iterator (this will go row by row)
iter_data = your_dataframe.iterrows()

Now, every row needs to be transformed into a dictionary and use this dict for instantiating your model (in this case, Product())

# python 2.x
map(lambda (i,data) : Product.objects.create(**dict(data)),iter_data

Done, check your database now.

to get all tables: (You may want to restrict schema to your schema)

select * from syscat.tables

to get all columns: (where tabname = your_tabname)

select * from syscat.columns

Best Approach

As @sat answer, good approach for getting color is

ResourcesCompat.getColor(getResources(), R.color.your_color, null);

or use below way when you don't have access to getResources() method.

Context context  = getContext(); // like Dialog class
ResourcesCompat.getColor(context.getResources(), R.color.your_color, null);

What i do is

public void someMethod(){
    ...
    ResourcesCompat.getColor(App.getRes(), R.color.your_color, null);
}

It is most simple to use anywhere in your app! Even in Util class or any class where you don't have Context or getResource()

Problem (When you don't have Context)

When you don't have Context access, like a method in your Util class.

Assume below method without Context.

public void someMethod(){
    ...
    // can't use getResource() without Context.
}

Now you will pass Context as a parameter in this method and use getResources().

public void someMethod(Context context){
    ...
    context.getResources...
}

So here is a Bonus unique solution by which you can access resources from anywhere like Util class . Add Resources to your Application class or Create one if does not exist.

import android.app.Application;
import android.content.res.Resources;

public class App extends Application {
    private static App mInstance;
    private static Resources res;


    @Override
    public void onCreate() {
        super.onCreate();
        mInstance = this;
        res = getResources();
    }

    public static App getInstance() {
        return mInstance;
    }

    public static Resources getResourses() {
        return res;
    }

}

Add name field to your manifest.xml <application tag. (If not added already)

<application
        android:name=".App"
        ...
        >
        ...
    </application>

Now you are good to go. Use ResourcesCompat.getColor(App.getRes(), R.color.your_color, null); anywhere in app.

When you create a database in Microsoft SQL Server you can have multiple file groups, where storage is created in multiple places, directories or disks. Each file group can be named. The PRIMARY file group is the default one, which is always created, and so the SQL you've given creates your table ON the PRIMARY file group.

See MSDN for the full syntax.

You must name your ng-app, giving your app a namespace; simply using ng-app is not enough.

Instead of:

<html ng-app>
...

You will need something like this instead:

<html ng-app="app">
...

Then, like so:

var app = angular.module("app", []).controller("ActionsController", function($scope){});

In Ubuntu you can apply this way,

to save file at some location (temporary) and then open and send it to API

      path = default_storage.save('static/tmp/' + f1.name, ContentFile(f1.read()))
      path12 = os.path.join(os.getcwd(), "static/tmp/" + f1.name)
      data={} #can be anything u want to pass along with File
      file1 = open(path12, 'rb')
      header = {"Content-Disposition": "attachment; filename=" + f1.name, "Authorization": "JWT " + token}
       res= requests.post(url,data,header)

You can also use equals:

 Integer a = 0;

 if (a.equals(0)) {
     // a == 0
 }

which is equivalent to:

 if (a.intValue() == 0) {
     // a == 0
 }

and also:

 if (a == 0) {

 }

(the Java compiler automatically adds intValue())

Note that autoboxing/autounboxing can introduce a significant overhead (especially inside loops).

strtok modifies its input string. It places null characters ('\0') in it so that it will return bits of the original string as tokens. In fact strtok does not allocate memory. You may understand it better if you draw the string as a sequence of boxes.

If you're really, absolutely positively sure that the NSURL is a file url, i.e. [url isFileURL] is guaranteed to return true in your case, then you can simply use:

[UIImage imageWithContentsOfFile:url.path]

You could try something like this:

public static void main (String[] args)
{
    Scanner input = new Scanner(System.in);
    double[] numbers = new double[5];

    for (int i = 0; i < numbers.length; i++)
    {
        System.out.println("Please enter number");
        numbers[i] = input.nextDouble();
    }
}

It seems pretty basic stuff unless I am misunderstanding you

No, according to Apple here:

Note: You cannot install apps from the App Store in simulation environments.

11. R (or another dependency) is out of date and you don't want to update it.

Warning this is not exactly best practice.

• Download the package source.
• Navigate to the DESCRIPTION file.

• Remove the offending line with your text editor e.g.

  Depends: R (>= 3.1.1)
  

• Install from local (i.e. from the parent directory of DESCRIPTION) e.g.

  install.packages("foo", type="source", repos=NULL)
  

The Web API basically return 4 type of object: void, HttpResponseMessage, IHttpActionResult, and other strong types. The first version of the Web API returns HttpResponseMessage which is pretty straight forward HTTP response message.

The IHttpActionResult was introduced by WebAPI 2 which is a kind of wrap of HttpResponseMessage. It contains the ExecuteAsync() method to create an HttpResponseMessage. It simplifies unit testing of your controller.

Other return type are kind of strong typed classes serialized by the Web API using a media formatter into the response body. The drawback was you cannot directly return an error code such as a 404. All you can do is throwing an HttpResponseException error.

Sql Server fire this error when your application don't have enough rights to access the database. there are several reason about this error . To fix this error you should follow the following instruction.

1. Try to connect sql server from your server using management studio . if you use windows authentication to connect sql server then set your application pool identity to server administrator .

2. if you use sql server authentication then check you connection string in web.config of your web application and set user id and password of sql server which allows you to log in .

3. if your database in other server(access remote database) then first of enable remote access of sql server form sql server property from sql server management studio and enable TCP/IP form sql server configuration manager .

4. after doing all these stuff and you still can't access the database then check firewall of server form where you are trying to access the database and add one rule in firewall to enable port of sql server(by default sql server use 1433 , to check port of sql server you need to check sql server configuration manager network protocol TCP/IP port).

5. if your sql server is running on named instance then you need to write port number with sql serer name for example 117.312.21.21/nameofsqlserver,1433.

6. If you are using cloud hosting like amazon aws or microsoft azure then server or instance will running behind cloud firewall so you need to enable 1433 port in cloud firewall if you have default instance or specific port for sql server for named instance.

7. If you are using amazon RDS or SQL azure then you need to enable port from security group of that instance.

8. If you are accessing sql server through sql server authentication mode them make sure you enabled "SQL Server and Windows Authentication Mode" sql server instance property.

   9. Restart your sql server instance after making any changes in property as some changes will require restart.

if you further face any difficulty then you need to provide more information about your web site and sql server .
