Read Ricardo's response first. This worked for me.

However, there exists a scenario where this won't work if the running container was kicked off using docker-compose. This is because docker-compose (I'm running docker 1.17) creates a new network. The way to address this scenario would be

docker network ls

Then append the following docker run -d --name sqlplus --link db:db -p 1521:1521 sqlplus --net network_name

You can use zip:

>>> a = [1, 2, 3]
>>> b = ['a', 'b', 'c']
>>> for x, y in zip(a, b):
...   print x, y
... 
1 a
2 b
3 c

The term Endpoint was initially used for WCF services. Later even though this word is being used synonymous to API resources, REST recommends to call these URI (URI[s] which understand HTTP verbs and follow REST architecture) as "Resource".

In a nutshell, a Resource or Endpoint is kind of an entry point to a remotely hosted application which lets the users to communicate to it via HTTP protocol.

I had this error come up today due to a defect in code that was posting back a tremendous amount of times causing IIS to be flooded with requests. This essentially locked up IIS and so when I tried to debug, it 'timed out' trying to start the debugger. I simply restarted IIS, which took a few minutes, and it solved the issue.

I sure do wish this error was less generic, seems like there are several different ways to produce it.

As addition to other answers, @JsonProperty annotation is really important if you use the @JsonCreator annotation in classes which do not have a no-arg constructor.

public class ClassToSerialize {

    public enum MyEnum {
        FIRST,SECOND,THIRD
    }

    public String stringValue = "ABCD";
    public MyEnum myEnum;


    @JsonCreator
    public ClassToSerialize(MyEnum myEnum) {
        this.myEnum = myEnum;
    }

    public static void main(String[] args) throws IOException {
        ObjectMapper mapper = new ObjectMapper();

        ClassToSerialize classToSerialize = new ClassToSerialize(MyEnum.FIRST);
        String jsonString = mapper.writeValueAsString(classToSerialize);
        System.out.println(jsonString);
        ClassToSerialize deserialized = mapper.readValue(jsonString, ClassToSerialize.class);
        System.out.println("StringValue: " + deserialized.stringValue);
        System.out.println("MyEnum: " + deserialized.myEnum);
    }
}

In this example the only constructor is marked as @JsonCreator, therefore Jackson will use this constructor to create the instance. But the output is like:

Serialized: {"stringValue":"ABCD","myEnum":"FIRST"}

Exception in thread "main" com.fasterxml.jackson.databind.exc.InvalidFormatException: Can not construct instance of ClassToSerialize$MyEnum from String value 'stringValue': value not one of declared Enum instance names: [FIRST, SECOND, THIRD]

But after the addition of the @JsonProperty annotation in the constructor:

@JsonCreator
public ClassToSerialize(@JsonProperty("myEnum") MyEnum myEnum) {
    this.myEnum = myEnum;
}

The deserialization is successful:

Serialized: {"myEnum":"FIRST","stringValue":"ABCD"}

StringValue: ABCD

MyEnum: FIRST

Bundler now has a bundle remove GEM_NAME command (since v1.17.0, 25 October 2018).

If this really is a QA issue and you can't change the code. Setup a new server instance on the machine and setup the language as "British English"

If you want n bits specific then you could first create a bitmask and then AND it with your number to take the desired bits.

Simple function to create mask from bit a to bit b.

unsigned createMask(unsigned a, unsigned b)
{
   unsigned r = 0;
   for (unsigned i=a; i<=b; i++)
       r |= 1 << i;

   return r;
}

You should check that a<=b.

If you want bits 12 to 16 call the function and then simply & (logical AND) r with your number N

r = createMask(12,16);
unsigned result = r & N;

If you want you can shift the result. Hope this helps

A solution is add the corresponding Debian package way to your repository. For this, type the below commands:

echo "deb ftp.us.debian.org/debian wheezy main" >> /etc/apt/sources.list
sudo apt-get update
sudo apt-get install ia32-libs-i386

The first line writes in the end of the sources.list file the package way. This works for me. I wish that helps you.

Best way to do this is

echo "<pre>".print_r($array,true)."</pre>";

Example:

$array=array("foo"=>"999","bar"=>"888","poo"=>array("x"=>"111","y"=>"222","z"=>"333"));
echo "<pre>".print_r($array,true)."</pre>";

Result:

Array
(
    [foo] => 999
    [bar] => 888
    [poo] => Array
        (
            [x] => 111
            [y] => 222
            [z] => 333
        )
)

About the second parameter of print_r "true" from the documentation:

When this parameter is set to TRUE, print_r() will return the information rather than print it.

working in my application

The best way I found so far is to go to the Oauth playground here: https://developers.google.com/oauthplayground/

1. Select the relevant google api category, and then select the scope inside that category in the UI.
2. Get the authorization code by clicking "authorize API" blue button. Exchange authorization code for token by clicking the blue button.
3. Store the OAuth2 token and use it as shown below.

In the HTTP header for the REST API request, add: "Authorization: Bearer ". Here, Authorization is the key, and "Bearer ". For example: "Authorization: Bearer za29.KluqA3vRtZChWfJDabcdefghijklmnopqrstuvwxyz6nAZ0y6ElzDT3yH3MT5"

Since you are explicitly also asking to handle columns that haven't yet been filled out, and I assume also don't want to mess with them if they have a word instead of a number, you might consider this:

=If(IsNumber(K23), If(K23 > 0, ........., 0), 0)

This just says... If K23 is a number; And if that number is greater than zero; Then do something ......... Otherwise, return zero.

In ........., you might put your division equation there, such as A1/K23, and you can rest assured that K23 is a number which is greater than zero.

Update: This answer is outdated as newer versions of libraries mentioned are released since then.

Socket.IO v0.9 is outdated and a bit buggy, and Engine.IO is the interim successor. Socket.IO v1.0 (which will be released soon) will use Engine.IO and be much better than v0.9. I'd recommend you to use Engine.IO until Socket.IO v1.0 is released.

"ws" does not support fallback, so if the client browser does not support websockets, it won't work, unlike Socket.IO and Engine.IO which uses long-polling etc if websockets are not available. However, "ws" seems like the fastest library at the moment.

See my article comparing Socket.IO, Engine.IO and Primus: https://medium.com/p/b63bfca0539

Note: This answer is sort of outdated (from 2008). Please use the solution below with care!!

Here is a page that details the problem and a solution (search the page for the text Wrapping sys.stdout into an instance):

    sys.stdout = codecs.getwriter(locale.getpreferredencoding())(sys.stdout); \
    line = u"\u0411\n"; print type(line), len(line); \

There's some more information on that page, well worth a read.

If you're using a graphical tool. It shows you the schema right next to the table name. In case of DB Browser For Sqlite, click to open the database(top right corner), navigate and open your database, you'll see the information populated in the table as below.

right click on the record/table_name, click on copy create statement and there you have it.

Hope it helped some beginner who failed to work with the commandline.

If .val() is not working, I would suggest you to use the .attr() attribute

In your PagerAdapter override getItemPosition

@Override
public int getItemPosition(Object object) {
// POSITION_NONE makes it possible to reload the PagerAdapter
return POSITION_NONE;
}

After that add viewPager.getAdapter().notifyDataSetChanged(); this code like below

viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
        @Override
        public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

        }

        @Override
        public void onPageSelected(int position) {
            viewPager.getAdapter().notifyDataSetChanged();
        }

        @Override
        public void onPageScrollStateChanged(int state) {

        }
    });

should work.

My way on Windows 8

1. Add a directory with ssh-keygen to the system PATH variable, usually C:\Program Files (x86)\Git\bin

2. Open CMD, go to C:\Users\Me\

3. Generate SSH key ssh-keygen -t rsa

   Enter file in which to save the key (//.ssh/id_rsa): .ssh/id_rsa (change a default incorrect path to .ssh/somegoodname_rsa)

4. Add the key to Heroku heroku keys:add

   Select a created key from a list

5. Go to your app directory, write some beautiful code

6. Init a git repo git init git add . git commit -m 'chore(release): v0.0.1

7. Create Heroku application heroku create

8. Deploy your app git push heroku master

9. Open your app heroku open

Use tokenGroups:

DirectorySearcher ds = new DirectorySearcher();
ds.Filter = String.Format("(&(objectClass=user)(sAMAccountName={0}))", username);
SearchResult sr = ds.FindOne();

DirectoryEntry user = sr.GetDirectoryEntry();
user.RefreshCache(new string[] { "tokenGroups" });

for (int i = 0; i < user.Properties["tokenGroups"].Count; i++) {
    SecurityIdentifier sid = new SecurityIdentifier((byte[]) user.Properties["tokenGroups"][i], 0);
    NTAccount nt = (NTAccount)sid.Translate(typeof(NTAccount));
    //do something with the SID or name (nt.Value)
}

Note: this only gets security groups

It is dirty better use the overflow: hidden; hack:

<div class="container">
  <div style="float: left;">Left Div</div>
  <div style="float: right;">Right Div</div>
</div>

.container { overflow: hidden; }

Or if you are going to do some fancy CSS3 drop-shadow stuff and you get in trouble with the above solution:

http://web.archive.org/web/20120414135722/http://fordinteractive.com/2009/12/goodbye-overflow-clearing-hack

PS

If you want to go for clean I would rather worry about that inline javascript rather than the overflow: hidden; hack :)

The simplest way is to use itertools.product:

a = ["foo", "melon"]
b = [True, False]
c = list(itertools.product(a, b))
>> [("foo", True), ("foo", False), ("melon", True), ("melon", False)]

simply concatenate both , but cast them first as below

select cast(concat(Cast(DateField as varchar), ' ', Cast(TimeField as varchar)) as datetime) as DateWithTime from TableName;

You can also save as a file: rdd.saveAsTextFile("alicia.txt")

DataGrip has the same functionality as pgAdmin. You can right click on a table and you will see option to auto-generate create table statement.

the following code worked fine for me. kindly check other setting in your web config

 <system.webServer>
     <defaultDocument>
            <files>
                <clear />               
                <add value="Login.aspx"/>
            </files>
        </defaultDocument>
    </system.webServer>

I agree with Jim Blizard. The database is not the part of your technology stack that should send emails. For example, what if you send an email but then roll back the change that triggered that email? You can't take the email back.

It's better to send the email in your application code layer, after your app has confirmed that the SQL change was made successfully and committed.

Ternary way

my_string.include?('ahr') ? (puts 'String includes ahr') : (puts 'String does not include ahr')

OR

puts (my_string.include?('ahr') ? 'String includes ahr' : 'String not includes ahr')

Input Dimension Clarified:

Not a direct answer, but I just realized the word Input Dimension could be confusing enough, so be wary:

It (the word dimension alone) can refer to:

a) The dimension of Input Data (or stream) such as # N of sensor axes to beam the time series signal, or RGB color channel (3): suggested word=> "InputStream Dimension"

b) The total number /length of Input Features (or Input layer) (28 x 28 = 784 for the MINST color image) or 3000 in the FFT transformed Spectrum Values, or

"Input Layer / Input Feature Dimension"

c) The dimensionality (# of dimension) of the input (typically 3D as expected in Keras LSTM) or (#RowofSamples, #of Senors, #of Values..) 3 is the answer.

"N Dimensionality of Input"

d) The SPECIFIC Input Shape (eg. (30,50,50,3) in this unwrapped input image data, or (30, 250, 3) if unwrapped Keras:

Keras has its input_dim refers to the Dimension of Input Layer / Number of Input Feature

model = Sequential()
model.add(Dense(32, input_dim=784))  #or 3 in the current posted example above
model.add(Activation('relu'))

In Keras LSTM, it refers to the total Time Steps

The term has been very confusing, is correct and we live in a very confusing world!!

I find one of the challenge in Machine Learning is to deal with different languages or dialects and terminologies (like if you have 5-8 highly different versions of English, then you need to very high proficiency to converse with different speakers). Probably this is the same in programming languages too.

For this specific use-case using try..except..else is the cleanest solution, the else clause will be executed if no exception was raised.

NOTE: The else clause must follow all except clauses

for i in iterator:
    try:
        # Do something.
    except:
        # Handle exception
    else:
        # Continue doing something

You may also combine cut and paste:

paste <(cut -f2 file.txt) <(cut -f1 file.txt)

via comments: It's possible to avoid bashisms and remove one instance of cut by doing:

paste file.txt file.txt | cut -f2,3

I had the same problem using Apache commons-fileupload. I did not find out what causes the problems especially because I have the UTF-8 encoding in the following places: 1. HTML meta tag 2. Form accept-charset attribute 3. Tomcat filter on every request that sets the "UTF-8" encoding

-> My solution was to especially convert Strings from ISO-8859-1 (or whatever is the default encoding of your platform) to UTF-8:

new String (s.getBytes ("iso-8859-1"), "UTF-8");

hope that helps

Edit: starting with Java 7 you can also use the following:

new String (s.getBytes (StandardCharsets.ISO_8859_1), StandardCharsets.UTF_8);

I had to use the "=" binding instead of "&" because that was not working. Strange behavior.

I had a similar error, but it was because I had created a has_one relationship and subsequently deleted the model that it had_one of. I just forgot to delete the has_one relationship from the remaining model.

You can do :

 System.out.println(nir[0].length);

But be aware that there's no real two-dimensional array in Java. Each "first level" array contains another array. Each of these arrays can be of different sizes. nir[0].length isn't necessarily the same size as nir[1].length.

To complete the previous answers, one may need a collection of objects from his CSV File, either parsed by the TextFieldParser or the string.Split method, and then each line converted to an object via Reflection. You obviously first need to define a class that matches the lines of the CSV file.

I used the simple CSV Serializer from Michael Kropat found here: Generic class to CSV (all properties) and reused his methods to get the fields and properties of the wished class.

I deserialize my CSV file with the following method:

public static IEnumerable<T> ReadCsvFileTextFieldParser<T>(string fileFullPath, string delimiter = ";") where T : new()
{
    if (!File.Exists(fileFullPath))
    {
        return null;
    }

    var list = new List<T>();
    var csvFields = GetAllFieldOfClass<T>();
    var fieldDict = new Dictionary<int, MemberInfo>();

    using (TextFieldParser parser = new TextFieldParser(fileFullPath))
    {
        parser.SetDelimiters(delimiter);

        bool headerParsed = false;

        while (!parser.EndOfData)
        {
            //Processing row
            string[] rowFields = parser.ReadFields();
            if (!headerParsed)
            {
                for (int i = 0; i < rowFields.Length; i++)
                {
                    // First row shall be the header!
                    var csvField = csvFields.Where(f => f.Name == rowFields[i]).FirstOrDefault();
                    if (csvField != null)
                    {
                        fieldDict.Add(i, csvField);
                    }
                }
                headerParsed = true;
            }
            else
            {
                T newObj = new T();
                for (int i = 0; i < rowFields.Length; i++)
                {
                    var csvFied = fieldDict[i];
                    var record = rowFields[i];

                    if (csvFied is FieldInfo)
                    {
                        ((FieldInfo)csvFied).SetValue(newObj, record);
                    }
                    else if (csvFied is PropertyInfo)
                    {
                        var pi = (PropertyInfo)csvFied;
                        pi.SetValue(newObj, Convert.ChangeType(record, pi.PropertyType), null);
                    }
                    else
                    {
                        throw new Exception("Unhandled case.");
                    }

                {
                    list.Add(newObj);
                }
            }
        }
    }
    return list;
}

public static IEnumerable<MemberInfo> GetAllFieldOfClass<T>()
{
    return
        from mi in typeof(T).GetMembers(BindingFlags.Public | BindingFlags.Instance | BindingFlags.Static)
        where new[] { MemberTypes.Field, MemberTypes.Property }.Contains(mi.MemberType)
        let orderAttr = (ColumnOrderAttribute)Attribute.GetCustomAttribute(mi, typeof(ColumnOrderAttribute))
        orderby orderAttr == null ? int.MaxValue : orderAttr.Order, mi.Name

If they have error pages enabled, you can go to a non-existent page and look at the bottom of the 404 page.

I don't see php file, but that could be that -
replace in your php file:

$query_age = $_GET['query_age'];

with:

$query_age = (isset($_GET['query_age']) ? $_GET['query_age'] : null);

Most probably, at first time you running your script without ?query_age=[something] and $_GET has no key like query_age.

It is impossible for any program, in any language, to handle a SIGKILL. This is so it is always possible to terminate a program, even if the program is buggy or malicious. But SIGKILL is not the only means for terminating a program. The other is to use a SIGTERM. Programs can handle that signal. The program should handle the signal by doing a controlled, but rapid, shutdown. When a computer shuts down, the final stage of the shutdown process sends every remaining process a SIGTERM, gives those processes a few seconds grace, then sends them a SIGKILL.

The way to handle this for anything other than kill -9 would be to register a shutdown hook. If you can use (SIGTERM) kill -15 the shutdown hook will work. (SIGINT) kill -2 DOES cause the program to gracefully exit and run the shutdown hooks.

Registers a new virtual-machine shutdown hook.

The Java virtual machine shuts down in response to two kinds of events:

• The program exits normally, when the last non-daemon thread exits or when the exit (equivalently, System.exit) method is invoked, or
• The virtual machine is terminated in response to a user interrupt, such as typing ^C, or a system-wide event, such as user logoff or system shutdown.

I tried the following test program on OSX 10.6.3 and on kill -9 it did NOT run the shutdown hook, as expected. On a kill -15 it DOES run the shutdown hook every time.

public class TestShutdownHook
{
    public static void main(String[] args) throws InterruptedException
    {
        Runtime.getRuntime().addShutdownHook(new Thread()
        {
            @Override
            public void run()
            {
                System.out.println("Shutdown hook ran!");
            }
        });

        while (true)
        {
            Thread.sleep(1000);
        }
    }
}

There isn't any way to really gracefully handle a kill -9 in any program.

In rare circumstances the virtual machine may abort, that is, stop running without shutting down cleanly. This occurs when the virtual machine is terminated externally, for example with the SIGKILL signal on Unix or the TerminateProcess call on Microsoft Windows.

The only real option to handle a kill -9 is to have another watcher program watch for your main program to go away or use a wrapper script. You could do with this with a shell script that polled the ps command looking for your program in the list and act accordingly when it disappeared.

#!/usr/bin/env bash

java TestShutdownHook
wait
# notify your other app that you quit
echo "TestShutdownHook quit"

I also have same problem and in my case I injected reducer properly but still I couldn't type in field. It turns out if you are using immutable you have to use redux-form/immutable.

import {reducer as formReducer} from 'redux-form/immutable';
const reducer = combineReducers{

    form: formReducer
}
import {Field, reduxForm} from 'redux-form/immutable';
/* your component */

Notice that your state should be like state->form otherwise you have to explicitly config the library also the name for state should be form. see this issue

According to this thread:

The peer-to-peer Wi-Fi implemented by iOS (and recent versions of OS X) is not compatible with Wi-Fi Direct. Note Just as an aside, you can access peer-to-peer Wi-Fi without using Multipeer Connectivity. The underlying technology is Bonjour + TCP/IP, and you can access that directly from your app. The WiTap sample code shows how.

i'd suggest shorter and faster approach:

printf("%.2f", ((signed long)(fVal * 100) * 0.01f));

this way you won't overflow int, plus multiplication by 100 shouldn't influence the significand/mantissa itself, because the only thing that really is changing is exponent.

As mentioned before there is nothing in the C# language that dictates the layout, I personally use regions, and I do something like this for an average class.

public class myClass
{
#region Private Members

#endregion
#region Public Properties

#endregion

#region Constructors

#endregion
#region Public Methods

#endregion
}

It makes sense to me anyway

The dot(.) signifies a class name while the hash (#) signifies an element with a specific id attribute. The class will apply to any element decorated with that particular class, while the # style will only apply to the element with that particular id.

Class name:

<style>
   .class { ... }
</style>

<div class="class"></div>
<span class="class></span>
<a href="..." class="class">...</a>

Named element:

<style>
   #name { ... }
</style>

<div id="name"></div>

Here is a very simplified explanation:

1. Your web browser downloads the web server's certificate, which contains the public key of the web server. This certificate is signed with the private key of a trusted certificate authority.

2. Your web browser comes installed with the public keys of all of the major certificate authorities. It uses this public key to verify that the web server's certificate was indeed signed by the trusted certificate authority.

3. The certificate contains the domain name and/or ip address of the web server. Your web browser confirms with the certificate authority that the address listed in the certificate is the one to which it has an open connection.

4. Your web browser generates a shared symmetric key which will be used to encrypt the HTTP traffic on this connection; this is much more efficient than using public/private key encryption for everything. Your browser encrypts the symmetric key with the public key of the web server then sends it back, thus ensuring that only the web server can decrypt it, since only the web server has its private key.

Note that the certificate authority (CA) is essential to preventing man-in-the-middle attacks. However, even an unsigned certificate will prevent someone from passively listening in on your encrypted traffic, since they have no way to gain access to your shared symmetric key.

x=3#rows
y=3#columns
a=[]#create an empty list first
for i in range(x):
    a.append([0]*y)#And again append empty lists to original list
    for j in range(y):
         a[i][j]=input("Enter the value")

If your widget is a Button:

<LinearLayout android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:weightSum="2"
    android:orientation="horizontal">
    <Button android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="somebutton"/>

    <TextView android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"/>
</LinearLayout>

I'm assuming you want your widget to take up one half, and another widget to take up the other half. The trick is using a LinearLayout, setting layout_width="fill_parent" on both widgets, and setting layout_weight to the same value on both widgets as well. If there are two widgets, both with the same weight, the LinearLayout will split the width between the two widgets.

The problem is that you mapped your servlet to /register.html and it expects POST method, because you implemented only doPost() method. So when you open register.html page, it will not open html page with the form but servlet that handles the form data.

Alternatively when you submit POST form to non-existing URL, web container will display 405 error (method not allowed) instead of 404 (not found).

To fix:

<servlet-mapping>
    <servlet-name>Register</servlet-name>
    <url-pattern>/Register</url-pattern>
</servlet-mapping>

Coming from emacs I've found that I like ctrl + keys to do stuff, and in vim I've found that both [ctrl + C] and [alt + backspace] will enter Normal mode from insert mode. You might try and see if any of those works out for you.

They say it right there in the documentation for the FPDF constructor:

FPDF([string orientation [, string unit [, mixed size]]])

This is the class constructor. It allows to set up the page size, the orientation and the unit of measure used in all methods (except for font sizes). Parameters ...

size

The size used for pages. It can be either one of the following values (case insensitive):

A3 A4 A5 Letter Legal

or an array containing the width and the height (expressed in the unit given by unit).

They even give an example with custom size:

Example with a custom 100x150 mm page size:

$pdf = new FPDF('P','mm',array(100,150));

There is another difference. An inline table-valued function can be inserted into, updated, and deleted from - just like a view. Similar restrictions apply - can't update functions using aggregates, can't update calculated columns, and so on.

It's actually quite easy to implement as a helper:

Handlebars.registerHelper('eachProperty', function(context, options) {
    var ret = "";
    for(var prop in context)
    {
        ret = ret + options.fn({property:prop,value:context[prop]});
    }
    return ret;
});

Then using it like so:

{{#eachProperty object}}
    {{property}}: {{value}}<br/>
{{/eachProperty }}

Note: the commit 5e1361c from brian m. carlson (bk2204) (for git 1.9/2.0 Q1 2014) deals with a special case in term of log decoration with tags:

log: properly handle decorations with chained tags

git log did not correctly handle decorations when a tag object referenced another tag object that was no longer a ref, such as when the second tag was deleted.
The commit would not be decorated correctly because parse_object had not been called on the second tag and therefore its tagged field had not been filled in, resulting in none of the tags being associated with the relevant commit.

Call parse_object to fill in this field if it is absent so that the chain of tags can be dereferenced and the commit can be properly decorated.
Include tests as well to prevent future regressions.

Example:

git tag -a tag1 -m tag1 &&
git tag -a tag2 -m tag2 tag1 &&
git tag -d tag1 &&
git commit --amend -m shorter &&
git log --no-walk --tags --pretty="%H %d" --decorate=full

You can do this:

df.rename(columns={ df.columns[1]: "whatever" })

The size_t type is the type returned by the sizeof operator. It is an unsigned integer capable of expressing the size in bytes of any memory range supported on the host machine. It is (typically) related to ptrdiff_t in that ptrdiff_t is a signed integer value such that sizeof(ptrdiff_t) and sizeof(size_t) are equal.

When writing C code you should always use size_t whenever dealing with memory ranges.

The int type on the other hand is basically defined as the size of the (signed) integer value that the host machine can use to most efficiently perform integer arithmetic. For example, on many older PC type computers the value sizeof(size_t) would be 4 (bytes) but sizeof(int) would be 2 (byte). 16 bit arithmetic was faster than 32 bit arithmetic, though the CPU could handle a (logical) memory space of up to 4 GiB.

Use the int type only when you care about efficiency as its actual precision depends strongly on both compiler options and machine architecture. In particular the C standard specifies the following invariants: sizeof(char) <= sizeof(short) <= sizeof(int) <= sizeof(long) placing no other limitations on the actual representation of the precision available to the programmer for each of these primitive types.

Note: This is NOT the same as in Java (which actually specifies the bit precision for each of the types 'char', 'byte', 'short', 'int' and 'long').

Remove "SSLv2ClientHello" from the enabled protocols on the client SSLSocket or HttpsURLConnection.

Add the following line to the beginning script1.py

#!/usr/bin/env python

and then make the script executable:

$ chmod +x script1.py

If the script resides in a directory that appears in your PATH variable, you can simply type

$ script1.py

Otherwise, you'll need to provide the full path (either absolute or relative). This includes the current working directory, which should not be in your PATH.

$ ./script1.py

How about defining your own view? I have used the class below, using a LinearLayout around a view whose background color is set. This allows me to pre-define layout parameters for it. If you don't need that just extend View and set the background color instead.

public class HorizontalRulerView extends LinearLayout {

    static final int COLOR = Color.DKGRAY;
    static final int HEIGHT = 2;
    static final int VERTICAL_MARGIN = 10;
    static final int HORIZONTAL_MARGIN = 5;
    static final int TOP_MARGIN = VERTICAL_MARGIN;
    static final int BOTTOM_MARGIN = VERTICAL_MARGIN;
    static final int LEFT_MARGIN = HORIZONTAL_MARGIN;
    static final int RIGHT_MARGIN = HORIZONTAL_MARGIN;

    public HorizontalRulerView(Context context) {
        this(context, null);
    }

    public HorizontalRulerView(Context context, AttributeSet attrs) {
        this(context, attrs, android.R.attr.textViewStyle);
    }

    public HorizontalRulerView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        setOrientation(VERTICAL);
        View v = new View(context);
        v.setBackgroundColor(COLOR);
        LayoutParams lp = new LayoutParams(
            LayoutParams.MATCH_PARENT,
            HEIGHT
        );
        lp.topMargin = TOP_MARGIN;
        lp.bottomMargin = BOTTOM_MARGIN;
        lp.leftMargin = LEFT_MARGIN;
        lp.rightMargin = RIGHT_MARGIN;
        addView(v, lp);
    }

}

Use it programmatically or in Eclipse (Custom & Library Views -- just pull it into your layout).

Use a generic comparator such as :

final class MapValueComparator<K,V extends Comparable<V>> implements Comparator<K> {

    private Map<K,V> map;

    private MapValueComparator() {
        super();
    }

    public MapValueComparator(Map<K,V> map) {
        this();
        this.map = map;
    }

    public int compare(K o1, K o2) {
        return map.get(o1).compareTo(map.get(o2));
    }
}

With the help of the given links I was able to solve the problem myself. The correct way is to get the resource ID with

getResources().getIdentifier("FILENAME_WITHOUT_EXTENSION",
                             "raw", getPackageName());

To get it as a InputStream

InputStream ins = getResources().openRawResource(
            getResources().getIdentifier("FILENAME_WITHOUT_EXTENSION",
            "raw", getPackageName()));

Processing is new but very, very good.

This is how I set it up:

1. Open the command prompt(CMD) as administrator.

2. Export the proxy settings :

   set http_proxy=http://username:password@proxyAddress:port

   set https_proxy=https://username:password@proxyAddress:port

3. Install the package you want to install:

   pip install PackageName

For example:

I fixed the same error by doing a Ruby reinstall via rvm:

rvm reinstall 1.9.3

I use the VFS API from Apache Commons, here is an example of how to monitor a file without much impact in performance:

Aside from the (excellent) suggestion to use TikZ, you could use gastex. I used this before TikZ was available and it did its job too.

NSString objects are immutable (they can't be changed), but there is a mutable subclass, NSMutableString, that gives you several methods for replacing characters within a string. It's probably your best bet.

On Itellij 15 CE, it's enough to just install Lombok Plugin (no additional configuration required).

Be careful when using the isa function. This will be true if your object is of the specified type or one of its subclasses. You have to use strcmp with the class function to test if the object is specifically that type and not a subclass.

Try this: Adding users to MySQL

You need grant privileges to the user if you want external acess to database(ie. web pages).

You will have to create an object out first. More about this here:

    // write to stdout
    out = System.out;
    out.println("Test 1");
    out.close();

I find it surprising that no one mentions data as an object. For me it's the cleanest and easiest way to pass data:

$('form#foo').submit(function () {
    $.ajax({
        url: 'http://foo.bar/some-ajax-script',
        type: 'POST',
        dataType: 'json',
        data: {
            'foo': 'some-foo-value',
            'bar': $('#bar').val()
        }
    }).always(function (response) {
        console.log(response);
    });

    return false;
});

Then, in the backend:

// Example in PHP
$_POST['foo'] // some-foo-value
$_POST['bar'] // value in #bar

Ext needs to inherit the base, so in your definition it should say:

public class Ext : Base { //...

Factory Pattern

class Point
{
public:
  static Point Cartesian(double x, double y);
private:
};

And if you compiler does not support Return Value Optimization, ditch it, it probably does not contain much optimization at all...

In Java 8 you can use the Stream interface:

return dvdList.stream().anyMatch(d -> d.getTitle().equalsIgnoreCase("SomeTitle"));

There is still a lot of confusion in understanding the scope of "protected internal" accessors, though most have the definition defined correctly. This helped me to understand the confusion between "protected" and "protected internal":

public is really public inside and outside the assembly (public internal / public external)

protected is really protected inside and outside the assembly (protected internal / protected external) (not allowed on top level classes)

private is really private inside and outside the assembly (private internal / private external) (not allowed on top level classes)

internal is really public inside the assembly but excluded outside the assembly like private (public internal / excluded external)

protected internal is really public inside the assembly but protected outside the assembly (public internal / protected external) (not allowed on top level classes)

As you can see protected internal is a very strange beast. Not intuitive.

That now begs the question why didn't Microsoft create a (protected internal / excluded external), or I guess some kind of "private protected" or "internal protected"? lol. Seems incomplete?

Added to the confusion is the fact you can nest public or protected internal nested members inside protected, internal, or private types. Why would you access a nested "protected internal" inside an internal class that excludes outside assembly access?

Microsoft says such nested types are limited by their parent type scope, but that's not what the compiler says. You can compiled protected internals inside internal classes which should limit scope to just the assembly.

To me this feels like incomplete design. They should have simplified scope of all types to a system that clearly consider inheritance but also security and hierarchy of nested types. This would have made the sharing of objects extremely intuitive and granular rather than discovering accessibility of types and members based on an incomplete scoping system.

After initializing your UI component and fill it with data. add those line to your on create method

Runnable runnable=new Runnable() {
        @Override
        public void run() {
            scrollView.fullScroll(ScrollView.FOCUS_DOWN);
        }
    };
    scrollView.post(runnable);

Got the same problem, found the following bug report in SQL Server 2012 If still relevant see conditions that cause the issue - there are some workarounds there as well (didn't try though). Failover or Restart Results in Reseed of Identity

We can use setTag() and getTag() to set and get custom objects as per our requirement. The setTag() method takes an argument of type Object, and getTag() returns an Object.

For example,

Person p = new Person();
p.setName("Ramkailash");
p.setId(2000001);
button1.setTag(p);

Fiddle with 3 working solutions in action.

Given an external JSON:

myurl = 'http://wikidata.org/w/api.php?action=wbgetentities&sites=frwiki&titles=France&languages=zh-hans|zh-hant|fr&props=sitelinks|labels|aliases|descriptions&format=json'

Solution 1: $.ajax() + jsonp:

$.ajax({

  // do my stuff
});

Solution 2: $.ajax()+json+&calback=?:

$.ajax({

Solution 3: $.getJSON()+calback=?:

#mybox:hover { display: none; }
#mybox:hover { visibility: hidden; }
#mybox:hover { background: none; }
#mybox:hover { color: green; }

though it should be noted that IE6 and below wont listen to the hover when it's not on an A tag. For that you have to incorporate JavaScript to add a class to the div during the hover.

Unfortunately, you have a malformed url query string, so a regex technique is most appropriate. See what I mean.

There is no need for capture groups. Just match id= then forget those characters with \K, then isolate the following one or more digital characters.

Code (Demo)

$str = 'producturl.php?id=736375493?=tm';
echo preg_match('~id=\K\d+~', $str, $out) ? $out[0] : 'no match';

Output:

736375493

There is no documented LEFT() function in Oracle. Find the full set here.

Probably what you have is a user-defined function. You can check that easily enough by querying the data dictionary:

select * from all_objects
where object_name = 'LEFT'

But there is the question of why the stored procedure works and the query doesn't. One possible solution is that the stored procedure is owned by another schema, which also owns the LEFT() function. They have granted rights on the procedure but not its dependencies. This works because stored procedures run with DEFINER privileges by default, so you run the stored procedure as if you were its owner.

If this is so then the data dictionary query I listed above won't help you: it will only return rows for objects you have rights on. In which case you will need to run the query as the stored procedure's owner or connect as a user with the rights to query DBA_OBJECTS instead.

Here's another way to do it in VBA.

Function ConvertToArray(ByVal value As String)
    value = StrConv(value, vbUnicode)
    ConvertToArray = Split(Left(value, Len(value) - 1), vbNullChar)
End Function
Sub example()
    Dim originalString As String
    originalString = "hi there"
    Dim myArray() As String
    myArray = ConvertToArray(originalString)
End Sub

Clearing a list in place will affect all other references of the same list.

For example, this method doesn't affect other references:

>>> a = [1, 2, 3]
>>> b = a
>>> a = []
>>> print(a)
[]
>>> print(b)
[1, 2, 3]

But this one does:

>>> a = [1, 2, 3]
>>> b = a
>>> del a[:]      # equivalent to   del a[0:len(a)]
>>> print(a)
[]
>>> print(b)
[]
>>> a is b
True

You could also do:

>>> a[:] = []

Can I write something like static class?

No, according to the C++11 N3337 standard draft Annex C 7.1.1:

Change: In C ++, the static or extern specifiers can only be applied to names of objects or functions. Using these specifiers with type declarations is illegal in C ++. In C, these specifiers are ignored when used on type declarations. Example:

static struct S {    // valid C, invalid in C++
  int i;
};

Rationale: Storage class specifiers don’t have any meaning when associated with a type. In C ++, class members can be declared with the static storage class specifier. Allowing storage class specifiers on type declarations could render the code confusing for users.

And like struct, class is also a type declaration.

The same can be deduced by walking the syntax tree in Annex A.

It is interesting to note that static struct was legal in C, but had no effect: Why and when to use static structures in C programming?

If your existing code is already relying on from datetime import datetime, you can also simply also import date

from datetime import datetime, timedelta, date
print isinstance(datetime.today().date(), date)

The best solution is the word-spacing property.

Add the <p> in a container with a specific size (example 300px) and after you have to add that size as the value in the word-spacing.

HTML

<div>
 <p>Sentence Here</p>
</div>

CSS

div {
 width: 300px;
}

p {
 width: auto;
 text-align: center;
 word-spacing: 300px;
}

In this way, your sentence will be always broken and set in a column, but the with of the paragraph will be dynamic.

Here an example Codepen

Try this with the + after [0-9]:

input type="text" pattern="[0-9]+" title="number only"

Never try to set the compiler in the CMakeLists.txt file.

See the CMake FAQ about how to use a different compiler:

https://gitlab.kitware.com/cmake/community/wikis/FAQ#how-do-i-use-a-different-compiler

(Note that you are attempting method #3 and the FAQ says "(avoid)"...)

We recommend avoiding the "in the CMakeLists" technique because there are problems with it when a different compiler was used for a first configure, and then the CMakeLists file changes to try setting a different compiler... And because the intent of a CMakeLists file should be to work with multiple compilers, according to the preference of the developer running CMake.

The best method is to set the environment variables CC and CXX before calling CMake for the very first time in a build tree.

After CMake detects what compilers to use, it saves them in the CMakeCache.txt file so that it can still generate proper build systems even if those variables disappear from the environment...

If you ever need to change compilers, you need to start with a fresh build tree.

Just add a file .gitkeep in every folder you want committed.

On windows do so by right clicking when in the folder and select: Git bash from here. Then type: touch .gitkeep

There is a better guide here for Windows:

https://shellcreeper.com/how-to-create-valid-ssl-in-localhost-for-xampp/

Basic steps:

1. Create an SSL certificate for your local domain using this: See more details in the link above https://gist.github.com/turtlepod/3b8d8d0eef29de019951aa9d9dcba546 https://gist.github.com/turtlepod/e94928cddbfc46cfbaf8c3e5856577d0

2. Install this cert in Windows (Trusted Root Certification Authorities) See more details in the link above

3. Add the site in Windows hosts (C:\Windows\System32\drivers\etc\hosts) E.g.: 127.0.0.1 site.test

4. Add the site in XAMPP conf (C:\xampp\apache\conf\extra\httpd-vhosts.conf) E.g.:

    <VirtualHost *:80>
       DocumentRoot "C:/xampp/htdocs"
       ServerName site.test
       ServerAlias *.site.test
    </VirtualHost>
    <VirtualHost *:443>
       DocumentRoot "C:/xampp/htdocs"
       ServerName site.test
       ServerAlias *.site.test
       SSLEngine on
       SSLCertificateFile "crt/site.test/server.crt"
       SSLCertificateKeyFile "crt/site.test/server.key"
    </VirtualHost>
   

5. Restart Apache and your browser and it's done!

I like the following because it is one line. Not perfect with DST changes but usually good enough for my needs.

var fiveDaysAgo = new Date(new Date() - (1000*60*60*24*5));

This solution preserves the index of the df2 DataFrame, unlike any solution that uses tolist():

df3 = df2.teams.apply(pd.Series)
df3.columns = ['team1', 'team2']

Here's the result:

  team1 team2
0    SF   NYG
1    SF   NYG
2    SF   NYG
3    SF   NYG
4    SF   NYG
5    SF   NYG
6    SF   NYG

The right way to update the page currently displayed in the user's browser (without reloading it) is to have some code executing in the browser update the page's DOM.

That code is typically javascript that is embedded in or linked from the HTML page, hence the AJAX suggestion. (In fact, if we assume that the updated text comes from the server via an HTTP request, this is classic AJAX.)

It is also possible to implement this kind of thing using some browser plugin or add-on, though it may be tricky for a plugin to reach into the browser's data structures to update the DOM. (Native code plugins normally write to some graphics frame that is embedded in the page.)

For the sake of completion:

 apply(people[,-1], 2, function(x) sum(x))
#Height Weight 
#   199    425 

My only doubt would be how applicable this technique would be on multi-byte strings, but if that's not a consideration, then I suspect you're covered. (If in doubt, mb_substr() seems an obviously safe choice.)

However, from a big picture perspective, I have to wonder how often you need to access the 'n'th character in a string for this to be a key consideration.

In my current organization, we don't do this in master but do do it on both develop and release/ branches (we are using Git Flow), in order to generate snapshot builds.

As we are using a multi branch pipeline, we do this in the Jenkinsfile with the when{} syntax...

stage {
    when { 
        expression { 
            branch 'develop'
        }
    }
}

This is detailed in this blog post: https://jenkins.io/blog/2017/01/19/converting-conditional-to-pipeline/#longer-pipeline

You need "src/Hankees.txt"

Your file is in the source folder which is not counted as the working directory.\

Or you can move the file up to the root directory of your project and just use "Hankees.txt"

None of the above answers worked for me, here is my solution which updates a disabled input with the filename:

<script type="text/javascript"> 
  document.getElementById('img_name').onchange = function () {
  var filePath = this.value;
    if (filePath) {
      var fileName = filePath.replace(/^.*?([^\\\/]*)$/, '$1');
      document.getElementById('img_name_input').value = fileName;
    }
  };
</script>

Try this ..

    txtview.setCompoundDrawablesWithIntrinsicBounds(
                    R.drawable.image, 0, 0, 0);

Also see this.. http://developer.android.com/reference/android/widget/TextView.html

Try this in xml file

    <TextView
        android:id="@+id/txtStatus"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:drawableLeft="@drawable/image"
        android:drawablePadding="5dp"
        android:maxLines="1"
        android:text="@string/name"/>

You can certainly format the date yourself..

var mydate = new Date(form.startDate.value);
var month = ["January", "February", "March", "April", "May", "June",
"July", "August", "September", "October", "November", "December"][mydate.getMonth()];
var str = month + ' ' + mydate.getFullYear();

You can also use an external library, such as DateJS.

Here's a DateJS example:

<script src="http://www.datejs.com/build/date.js" type="text/javascript"></script>
<script>
   var mydate = new Date(form.startDate.value);
   var str = mydate.toString("MMMM yyyy");
   window.alert(str);
</script>

StringBuilder sb = new StringBuilder();

You can use sb.AppendLine() or sb.Append(Environment.NewLine);

Integer i = map.get(key);
if(i == null)
   i = (aValue)
map.put(key, i + 1);

or

Integer i = map.get(key);
map.put(key, i == null ? newValue : i + 1);

Integer is Primitive data types http://cs.fit.edu/~ryan/java/language/java-data.html, so you need to take it out, make some process, then put it back. if you have a value which is not Primitive data types, you only need to take it out, process it, no need to put it back into the hashmap.

You can do it like this:

function fillArray(value, len) {
  if (len == 0) return [];
  var a = [value];
  while (a.length * 2 <= len) a = a.concat(a);
  if (a.length < len) a = a.concat(a.slice(0, len - a.length));
  return a;
}

It doubles the array in each iteration, so it can create a really large array with few iterations.

Note: You can also improve your function a lot by using push instead of concat, as concat will create a new array each iteration. Like this (shown just as an example of how you can work with arrays):

function fillArray(value, len) {
  var arr = [];
  for (var i = 0; i < len; i++) {
    arr.push(value);
  }
  return arr;
}

I created this function to convert struct to JSON string by ignoring some fields. Hope it will help.

func GetJSONString(obj interface{}, ignoreFields ...string) (string, error) {
    toJson, err := json.Marshal(obj)
    if err != nil {
        return "", err
    }

    if len(ignoreFields) == 0 {
        return string(toJson), nil
    }

    toMap := map[string]interface{}{}
    json.Unmarshal([]byte(string(toJson)), &toMap)

    for _, field := range ignoreFields {
        delete(toMap, field)
    }

    toJson, err = json.Marshal(toMap)
    if err != nil {
        return "", err
    }
    return string(toJson), nil
}

Example: https://play.golang.org/p/nmq7MFF47Gp

You have some data that is being entered by users somewhere in the application.

1. the component in which the data is being entered should have this data in its state because it needs to manipulate and change it during data entry

2. anywhere else in the application the data should be passed down as props to all the other components

So yes the props are changing but they are changed at the 'source' and will then simply flow down from there. So props are immutable in the context of the component receiving them.

E.g. a reference data screen where users edit a list of suppliers would manage this in state, which would then have an action cause the updated data to be saved in ReferenceDataState which could be one level below AppState and then this supplier list would be passed as props to all the components that needed to use it.

Whilst you certainly can use MySQL's IF() control flow function as demonstrated by dbemerlin's answer, I suspect it might be a little clearer to the reader (i.e. yourself, and any future developers who might pick up your code in the future) to use a CASE expression instead:

UPDATE Table
SET    A = CASE
         WHEN A > 0 AND A < 1 THEN 1
         WHEN A > 1 AND A < 2 THEN 2
         ELSE A
       END
WHERE  A IS NOT NULL

Of course, in this specific example it's a little wasteful to set A to itself in the ELSE clause—better entirely to filter such conditions from the UPDATE, via the WHERE clause:

UPDATE Table
SET    A = CASE
         WHEN A > 0 AND A < 1 THEN 1
         WHEN A > 1 AND A < 2 THEN 2
       END
WHERE  (A > 0 AND A < 1) OR (A > 1 AND A < 2)

(The inequalities entail A IS NOT NULL).

Or, if you want the intervals to be closed rather than open (note that this would set values of 0 to 1—if that is undesirable, one could explicitly filter such cases in the WHERE clause, or else add a higher precedence WHEN condition):

UPDATE Table
SET    A = CASE
         WHEN A BETWEEN 0 AND 1 THEN 1
         WHEN A BETWEEN 1 AND 2 THEN 2
       END
WHERE  A BETWEEN 0 AND 2

Though, as dbmerlin also pointed out, for this specific situation you could consider using CEIL() instead:

UPDATE Table SET A = CEIL(A) WHERE A BETWEEN 0 AND 2

Since I have recently developed an Android application using gyroscope data (steady compass), I tried to collect a list with such devices. This is not an exhaustive list at all, but it is what I have so far:

I believe those who study typography would tell you that 66 characters per a line is supposed to be the most readable width for length. Even so, if you need to debug a machine remotely over an ssh session, most terminals default to 80 characters, 79 just fits, trying to work with anything wider becomes a real pain in such a case. You would also be suprised by the number of developers using vim + screen as a day to day environment.

in order:

FROM & JOINs determine & filter rows
WHERE more filters on the rows
GROUP BY combines those rows into groups
HAVING filters groups
ORDER BY arranges the remaining rows/groups
LIMIT filters on the remaining rows/groups

It's not called a tag; what you're looking for is called an html attribute.

$('div[imageId="imageN"]').each(function(i,el){
  $(el).html('changes');
  //do what ever you wish to this object :) 
});

Well, in Java, a variable can be final not just as a parameter, but as a class-level field, like

public class Test
{
 public final int a = 3;

or as a local variable, like

public static void main(String[] args)
{
 final int a = 3;

If you want to access and modify a variable from an anonymous class, you might want to make the variable a class-level variable in the enclosing class.

public class Test
{
 public int a;
 public void doSomething()
 {
  Runnable runnable =
   new Runnable()
   {
    public void run()
    {
     System.out.println(a);
     a = a+1;
    }
   };
 }
}

You can't have a variable as final and give it a new value. final means just that: the value is unchangeable and final.

And since it's final, Java can safely copy it to local anonymous classes. You're not getting some reference to the int (especially since you can't have references to primitives like int in Java, just references to Objects).

It just copies over the value of a into an implicit int called a in your anonymous class.

ES6

convert object to map:

const objToMap = (o) => new Map(Object.entries(o));

convert map to object:

const mapToObj = (m) => [...m].reduce( (o,v)=>{ o[v[0]] = v[1]; return o; },{} )

Note: the mapToObj function assumes map keys are strings (will fail otherwise)

I would prefer to make a function that doesn't work with strings:

'---------------------------------------------------------------------------------------
' Procedure : RemoveTimeFromDate
' Author    : berend.nieuwhof
' Date      : 15-8-2013
' Purpose   : removes the time part of a String and returns the date as a date
'---------------------------------------------------------------------------------------
'
Public Function RemoveTimeFromDate(DateTime As Date) As Date


    Dim dblNumber As Double

    RemoveTimeFromDate = CDate(Floor(CDbl(DateTime)))

End Function

Private Function Floor(ByVal x As Double, Optional ByVal Factor As Double = 1) As Double
    Floor = Int(x / Factor) * Factor
End Function

I learned from the other answers and decided to use this code throughout my site:

var query = require('url').parse(req.url,true).query;

Then you can just call

var id = query.id;
var option = query.option;

where the URL for get should be

/path/filename?id=123&option=456

JavaScript's object literal syntax, which is typically used to instantiate objects (seriously, no one uses new Object or new Array), is as follows:

var obj = {
    'key': 'value',
    'another key': 'another value',
     anUnquotedKey: 'more value!'
};

For arrays it's:

var arr = [
    'value',
    'another value',
    'even more values'
];

If you need objects within objects, that's fine too:

var obj = {
    'subObject': {
        'key': 'value'
    },
    'another object': {
         'some key': 'some value',
         'another key': 'another value',
         'an array': [ 'this', 'is', 'ok', 'as', 'well' ]
    }
}

This convenient method of being able to instantiate static data is what led to the JSON data format.

JSON is a little more picky, keys must be enclosed in double-quotes, as well as string values:

{"foo":"bar", "keyWithIntegerValue":123}

To avoid issues with trailing \, call it this way:

  string ParentFolder =  Directory.GetParent( folder.Trim('\\')).FullName;

If you're trying to check if someone is 18 years of age, using timedelta will not work correctly on some edge cases because of leap years. For example, someone born on January 1, 2000, will turn 18 exactly 6575 days later on January 1, 2018 (5 leap years included), but someone born on January 1, 2001, will turn 18 exactly 6574 days later on January 1, 2019 (4 leap years included). Thus, you if someone is exactly 6574 days old, you can't determine if they are 17 or 18 without knowing a little more information about their birthdate.

The correct way to do this is to calculate the age directly from the dates, by subtracting the two years, and then subtracting one if the current month/day precedes the birth month/day.

I had a similar issue with Angular and IIS throwing a 404 status code on manual refresh and tried the most voted solution but that did not work for me. Also tried a bunch of other solutions having to deal with WebDAV and changing handlers and none worked.

Luckily I found this solution and it worked (took out parts I didn't need). So if none of the above works for you or even before trying them, try this and see if that fixes your angular deployment on iis issue.

Add the snippet to your webconfig in the root directory of your site. From my understanding, it removes the 404 status code from any inheritance (applicationhost.config, machine.config), then creates a 404 status code at the site level and redirects back to the home page as a custom 404 page.

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <system.webServer>
    <httpErrors errorMode="Custom">
      <remove statusCode="404"/>
      <error statusCode="404" path="/index.html" responseMode="ExecuteURL"/>
    </httpErrors>
  </system.webServer>
</configuration>

Best Answer: Simply add http or https in your browser, the IP address, colon and port number. Example: https://123.23.145.67:80

I know this question is specific to sql server, but I'm using postgresql and came across this question, so for anybody else in a similar situation, there is the split_part(string text, delimiter text, field int) function.

You could make a recursive function do the work

• Let L = size(M)
• Let idx = zeros(L,1)
• Take length(L) as the maximum depth
• Loop for idx(depth) = 1:L(depth)
• If your depth is length(L), do the element operation, else call the function again with depth+1

Not as fast as vectorized methods if you want to check all the points, but if you don't need to evaluate most of them it can be quite a time saver.

I've used a technique similar to McVitie's, and only in stored procedures or scripts that are pretty long. I will break down certain functional portions like this:

BEGIN /** delete queries **/

DELETE FROM blah_blah

END /** delete queries **/

BEGIN /** update queries **/

UPDATE sometable SET something = 1

END /** update queries **/

This method shows up fairly nice in management studio and is really helpful in reviewing code. The collapsed piece looks sort of like:

BEGIN /** delete queries **/ ... /** delete queries **/

I actually prefer it this way because I know that my BEGIN matches with the END this way.

As I mentioned in my comment, I think the reason why this doesn't work is because the compiler can't infer types based on generic constraints.

Below is an alternative implementation that will compile. I've revised the IAccess interface to only have the T generic type parameter.

interface ISignatur<T>
{
    Type Type { get; }
}

interface IAccess<T>
{
    ISignatur<T> Signature { get; }
    T Value { get; set; }
}

class Signatur : ISignatur<bool>
{
    public Type Type
    {
        get { return typeof(bool); }
    }
}

class ServiceGate
{
    public IAccess<T> Get<T>(ISignatur<T> sig)
    {
        throw new NotImplementedException();
    }
}

static class Test
{
    static void Main()
    {
        ServiceGate service = new ServiceGate();
        var access = service.Get(new Signatur());
    }
}

SELECT *
FROM   tbl
WHERE  id = 1
ORDER  BY signin DESC
LIMIT  1;

The obvious index would be on (id), or a multicolumn index on (id, signin DESC).

Conveniently for the case, MySQL sorts NULL values last in descending order. That's what you typically want if there can be NULL values: the row with the latest not-null signin.

To get NULL values first:

ORDER BY signin IS NOT NULL, signin DESC

You may want to append more expressions to ORDER BY to get a deterministic pick from (potentially) multiple rows with NULL.
The same applies without NULL if signin is not defined UNIQUE.

The SQL standard does not explicitly define a default sort order for NULL values. The behavior varies quite a bit across different RDBMS. See:

• https://docs.mendix.com/refguide/null-ordering-behavior

But there are the NULLS FIRST / NULLS LAST clauses defined in the SQL standard and supported by most major RDBMS, but not by MySQL. See:

• SQL how to make null values come last when sorting ascending
• Sort by column ASC, but NULL values first?

Our issue was simply the port number on the endpoint was incorrectly set to 8080. Changed it to 8443 and it worked.

The MySQL documentation has information on mapping MySQL types to Java types. In general, for MySQL datetime and timestamps you should use java.sql.Timestamp. A few resources include:

EDIT:

As others have indicated, the suggestion of using strings may lead to issues.

There won't be much difference. Howver version 2 is easier when you have some calculations, aggregations, etc that should be joined outside of it

--Version 2 
SELECT p.Name, s.OrderQty 
FROM Product p 
INNER JOIN 
(SELECT ProductID, SUM(OrderQty) as OrderQty FROM SalesOrderDetail GROUP BY ProductID
HAVING SUM(OrderQty) >1000) s 
on p.ProductID = s.ProdctId 

try this:

string strTime = "04/30/2013 23:00";
DateTime dtTime;
if(DateTime.TryParseExact(strTime, "MM/dd/yyyy HH:mm",  
   System.Globalization.CultureInfo.InvariantCulture, 
   System.Globalization.DateTimeStyles.None, out dtTime))
 {
    Console.WriteLine(dtTime);
 }

The java compiler tries to interpret 600851475143 as a constant value of type int by default. This causes an error since 600851475143 can not be represented with an int.

To tell the compiler that you want the number interpretet as a long you have to add either l or L after it. Your number should then look like this 600851475143L.

Since some Fonts make it hard to distinguish "1" and lower case "l" from each other you should always use the upper case "L".

For .Net <= 4.0 Use the TimeSpan class.

TimeSpan t = TimeSpan.FromSeconds( secs );

string answer = string.Format("{0:D2}h:{1:D2}m:{2:D2}s:{3:D3}ms", 
                t.Hours, 
                t.Minutes, 
                t.Seconds, 
                t.Milliseconds);

(As noted by Inder Kumar Rathore) For .NET > 4.0 you can use

TimeSpan time = TimeSpan.FromSeconds(seconds);

//here backslash is must to tell that colon is
//not the part of format, it just a character that we want in output
string str = time .ToString(@"hh\:mm\:ss\:fff");

(From Nick Molyneux) Ensure that seconds is less than TimeSpan.MaxValue.TotalSeconds to avoid an exception.

Here the code i used for my app

This code will take a image from url and convert is to a byte array

byte[] logoImage = getLogoImage(IMAGEURL);

private byte[] getLogoImage(String url){
     try {
             URL imageUrl = new URL(url);
             URLConnection ucon = imageUrl.openConnection();

             InputStream is = ucon.getInputStream();
             BufferedInputStream bis = new BufferedInputStream(is);

             ByteArrayBuffer baf = new ByteArrayBuffer(500);
             int current = 0;
             while ((current = bis.read()) != -1) {
                  baf.append((byte) current);
             }

             return baf.toByteArray();
     } catch (Exception e) {
          Log.d("ImageManager", "Error: " + e.toString());
     }
     return null;
}

To save the image to db i used this code.

 public void insertUser(){
        SQLiteDatabase db = dbHelper.getWritableDatabase();
        String delSql = "DELETE FROM ACCOUNTS";
        SQLiteStatement delStmt = db.compileStatement(delSql);
        delStmt.execute();

        String sql = "INSERT INTO ACCOUNTS (account_id,account_name,account_image) VALUES(?,?,?)";
        SQLiteStatement insertStmt = db.compileStatement(sql);
        insertStmt.clearBindings();
        insertStmt.bindString(1, Integer.toString(this.accId));
        insertStmt.bindString(2,this.accName);
        insertStmt.bindBlob(3, this.accImage);
        insertStmt.executeInsert();
        db.close();
}

To retrieve the image back this is code i used.

public Account getCurrentAccount() {
    SQLiteDatabase db = dbHelper.getWritableDatabase();
    String sql = "SELECT * FROM ACCOUNTS";
    Cursor cursor = db.rawQuery(sql, new String[] {});

    if(cursor.moveToFirst()){
        this.accId  = cursor.getInt(0);
        this.accName = cursor.getString(1);
        this.accImage = cursor.getBlob(2);
    }
    if (cursor != null && !cursor.isClosed()) {
        cursor.close();
    }
    db.close();
    if(cursor.getCount() == 0){
        return null;
    } else {
        return this;
    }
}

Finally to load this image to a imageview

logoImage.setImageBitmap(BitmapFactory.decodeByteArray( currentAccount.accImage, 
        0,currentAccount.accImage.length));

If you want to get a object that is instance of Element, you must use document.activeElement, but if you want to get a object that is instance of Text, you must to use document.getSelection().focusNode.

I hope helps.

You can solve this issue be adding max-width:

#element {
   width: 100vw;
   height: 100vw;
   max-width: 100%;
}

When you using CSS to make the wrapper full width using the code width: 100vw; then you will notice a horizontal scroll in the page, and that happened because the padding and margin of html and body tags added to the wrapper size, so the solution is to add max-width: 100%

Use callbacks. Something like this should work based on your sample code.

function someFunc() {

callAjaxfunc(function() {
    console.log('Pass2');
});

}

function callAjaxfunc(callback) {
    //All ajax calls called here
    onAjaxSuccess: function() {
        callback();
    };
    console.log('Pass1');    
}

This will print Pass1 immediately (assuming ajax request takes atleast a few microseconds), then print Pass2 when the onAjaxSuccess is executed.

UPDATE `tbl_user` SET `name`=concat('tbl_user.first_name','tbl_user.last_name') WHERE student_roll>965

That actually depends on what you're looking for.

• If you want to test whether a sequence is actually a ndarray, a isinstance(..., np.ndarray) is probably the easiest. Make sure you don't reload numpy in the background as the module may be different, but otherwise, you should be OK. MaskedArrays, matrix, recarray are all subclasses of ndarray, so you should be set.
• If you want to test whether a scalar is a numpy scalar, things get a bit more complicated. You could check whether it has a shape and a dtype attribute. You can compare its dtype to the basic dtypes, whose list you can find in np.core.numerictypes.genericTypeRank. Note that the elements of this list are strings, so you'd have to do a tested.dtype is np.dtype(an_element_of_the_list)...

$(this).value is attempting to call the 'value' property of a jQuery object, which does not exist. Native JavaScript does have a 'value' property on certain HTML objects, but if you are operating on a jQuery object you must access the value by calling $(this).val().

mvn clean install -U

-U means force update of dependencies.

If you want to update a single dependency without clean or -U you could just remove it from your local repo and then build.

I faced the same issue and It is really strange that the same code works in few case whereas it failed in some random cases.

I got it fixed by just making sure the proper setter/getter (Making sure the case sensitivity)

Git ignores folders if you write:

/js

but it can't add exceptions if you do: !/js/jquery or !/js/jquery/ or !/js/jquery/*

You must write:

/js/* 

and only then you can except subfolders like this

!/js/jquery

player.setDataSource(afd.getFileDescriptor(),afd.getStartOffset(),afd.getLength());

Your version would work if you had only one file in the assets directory. The asset directory contents are not actually 'real files' on disk. All of them are put together one after another. So, if you do not specify where to start and how many bytes to read, the player will read up to the end (that is, will keep playing all the files in assets directory)

M2_HOME (and the like) is not to be used as of Maven 3.5.0. See MNG-5607 and Release Notes for details.

I've only ever used Class.cast(Object) to avoid warnings in "generics land". I often see methods doing things like this:

@SuppressWarnings("unchecked")
<T> T doSomething() {
    Object o;
    // snip
    return (T) o;
}

It's often best to replace it by:

<T> T doSomething(Class<T> cls) {
    Object o;
    // snip
    return cls.cast(o);
}

That's the only use case for Class.cast(Object) I've ever come across.

Regarding compiler warnings: I suspect that Class.cast(Object) isn't special to the compiler. It could be optimized when used statically (i.e. Foo.class.cast(o) rather than cls.cast(o)) but I've never seen anybody using it - which makes the effort of building this optimization into the compiler somewhat worthless.

Import the catch-exception library, and use that. It's much cleaner than the ExpectedException rule or a try-catch.

Example form their docs:

import static com.googlecode.catchexception.CatchException.*;
import static com.googlecode.catchexception.apis.CatchExceptionHamcrestMatchers.*;

// given: an empty list
List myList = new ArrayList();

// when: we try to get the first element of the list
catchException(myList).get(1);

// then: we expect an IndexOutOfBoundsException with message "Index: 1, Size: 0"
assertThat(caughtException(),
  allOf(
    instanceOf(IndexOutOfBoundsException.class),
    hasMessage("Index: 1, Size: 0"),
    hasNoCause()
  )
);

One additional implementation, which uses Newtonsoft.Json binary JSON and does not require marking everything with the [Serializable] attribute. Only one drawback is that an object has to be wrapped in anonymous class, so byte array obtained with binary serialization can be different from this one.

public static byte[] ConvertToBytes(object obj)
{
    using (var ms = new MemoryStream())
    {
        using (var writer = new BsonWriter(ms))
        {
            var serializer = new JsonSerializer();
            serializer.Serialize(writer, new { Value = obj });
            return ms.ToArray();
        }
    }
}

Anonymous class is used because BSON should start with a class or array. I have not tried to deserialize byte[] back to object and not sure if it works, but have tested the speed of conversion to byte[] and it completely satisfies my needs.

I had the same problem;

textStatus = 'error'
errorThrown = (empty)
xhr.status = 0

That fits my problem exactly. It turns out that when I was loading the HTML-page from my own computer this problem existed, but when I loaded the HTML-page from my webserver it went alright. Then I tried to upload it to another domain, and again the same error occoured. Seems to be a cross-domain problem. (in my case at least)

I have tried calling it this way also:

var request = $.ajax({
url: "http://crossdomain.url.net/somefile.php", dataType: "text",
crossDomain: true,
xhrFields: {
withCredentials: true
}
});

but without success.

This post solved it for me: jQuery AJAX cross domain

The most recommended way to do is to use format method. Read more about it here

a, b = 1, 2

print("a={0},b={1}".format(a, b))

It seems that you are using the 64-bit version of the tool to install a 32-bit/x86 architecture application. Look for the 32-bit version of the tool here:

C:\Windows\Microsoft.NET\Framework\v4.0.30319

and it should install your 32-bit application just fine.

Just you need to define an application name like below which will work:

<application
  android:name="ApplicationName" android:icon="@drawable/icon">
</application>

It appears Swift applications don't run on OS X 10.7. I just created a simple GUI application (a view, a lable, a button) which runs fine on Mavericks. The base SDK is set to 10.9 and the deployment target to 10.7. I copied that application from the DerivedData folder over to my 10.7 virtual machine, and it crashs when starting, show this error:

NUL in Windows seems to be actually a virtual path in any folder. Just like .., . in any filesystem.

Use any folder followed with NUL will work.

Example,

echo 1 > nul
echo 1 > c:\nul
echo 1 > c:\users\nul
echo 1 > c:\windows\nul

have the same effect as /dev/null on Linux.

This was tested on Windows 7, 64 bit.

You can access Globals entity from any point of your App via Angular dependency injection. If you want to output Globals.role value in some component's template, you should inject Globals through the component's constructor like any service:

// hello.component.ts
import { Component } from '@angular/core';
import { Globals } from './globals';

@Component({
  selector: 'hello',
  template: 'The global role is {{globals.role}}',
  providers: [ Globals ] // this depends on situation, see below
})

export class HelloComponent {
  constructor(public globals: Globals) {}
}

I provided Globals in the HelloComponent, but instead it could be provided in some HelloComponent's parent component or even in AppModule. It will not matter until your Globals has only static data that could not be changed (say, constants only). But if it's not true and for example different components/services might want to change that data, then the Globals must be a singleton. In that case it should be provided in the topmost level of the hierarchy where it is going to be used. Let's say this is AppModule:

import { Globals } from './globals'

@NgModule({
  // ... imports, declarations etc
  providers: [
    // ... other global providers
    Globals // so do not provide it into another components/services if you want it to be a singleton
  ]
})

Also, it's impossible to use var the way you did, it should be

// globals.ts
import { Injectable } from '@angular/core';

@Injectable()
export class Globals {
  role: string = 'test';
}

Update

At last, I created a simple demo on stackblitz, where single Globals is being shared between 3 components and one of them can change the value of Globals.role.

The urls are different.

• http://localhost/AccountSvc/DataInquiry.asmx

vs.

• /acctinqsvc/portfolioinquiry.asmx

Resolve this issue first, as if the web server cannot resolve the URL you are attempting to POST to, you won't even begin to process the actions described by your request.

You should only need to create the WebRequest to the ASMX root URL, ie: http://localhost/AccountSvc/DataInquiry.asmx, and specify the desired method/operation in the SOAPAction header.

The SOAPAction header values are different.

• http://localhost/AccountSvc/DataInquiry.asmx/ + methodName

vs.

• http://tempuri.org/GetMyName

You should be able to determine the correct SOAPAction by going to the correct ASMX URL and appending ?wsdl

There should be a <soap:operation> tag underneath the <wsdl:operation> tag that matches the operation you are attempting to execute, which appears to be GetMyName.

There is no XML declaration in the request body that includes your SOAP XML.

You specify text/xml in the ContentType of your HttpRequest and no charset. Perhaps these default to us-ascii, but there's no telling if you aren't specifying them!

The SoapUI created XML includes an XML declaration that specifies an encoding of utf-8, which also matches the Content-Type provided to the HTTP request which is: text/xml; charset=utf-8

Hope that helps!

Assertions are disabled by default. To enable them we must run the program with -ea options (granularity can be varied). For example, java -ea AssertionsDemo.

There are two formats for using assertions:

1. Simple: eg. assert 1==2; // This will raise an AssertionError.
2. Better: assert 1==2: "no way.. 1 is not equal to 2"; This will raise an AssertionError with the message given displayed too and is thus better. Although the actual syntax is assert expr1:expr2 where expr2 can be any expression returning a value, I have used it more often just to print a message.

The simplest solution would be to simply use an actual button element, which centers its content vertically without any special CSS in most or all browsers, and can otherwise be styled as usual.

Because break can only be used inside a loop. It is used to break out of a loop (stop the loop).

You shouldn't use both ngRoute and UI-router. Here's a sample code for UI-router:

repoApp.config(function($stateProvider, $urlRouterProvider) {_x000D_
  _x000D_
  $stateProvider_x000D_
    .state('state1', {_x000D_
      url: "/state1",_x000D_
      templateUrl: "partials/state1.html",_x000D_
      controller: 'YourCtrl'_x000D_
    })_x000D_
    _x000D_
    .state('state2', {_x000D_
      url: "/state2",_x000D_
      templateUrl: "partials/state2.html",_x000D_
      controller: 'YourOtherCtrl'_x000D_
    });_x000D_
    $urlRouterProvider.otherwise("/state1");_x000D_
});_x000D_
//etc.

You can find a great answer on the difference between these two in this thread: What is the difference between angular-route and angular-ui-router?

You can also consult UI-Router's docs here: https://github.com/angular-ui/ui-router

Update: AdoptOpenJDK has changed its name to Adoptium, as part of its move to the Eclipse Foundation.

OpenJDK ? source code
Adoptium/AdoptOpenJDK ? builds

Difference between OpenJDK and AdoptOpenJDK

The first provides source-code, the other provides builds of that source-code.

• OpenJDK is an open-source project providing source-code (not builds) of an implementation of the Java platform as defined by:
  • the Java Specifications
  • Java Specification Request (JSR) documents published by Oracle via the Java Community Process
  • JDK Enhancement Proposal (JEP) documents published by Oracle via the OpenJDK project
• AdoptOpenJDK is an organization founded by some prominent members of the Java community aimed at providing binary builds and installers at no cost for users of Java technology.

Several vendors of Java & OpenJDK

Adoptium of the Eclipse Foundation, formerly known as AdoptOpenJDK, is only one of several vendors distributing implementations of the Java platform. These include:

• Eclipse Foundation (Adoptium/AdoptOpenJDK)
• Azul Systems
• Oracle
• Red Hat / IBM
• BellSoft
• SAP
• Amazon AWS
• … and more

See this flowchart of mine to help guide you in picking a vendor for an implementation of the Java platform. Click/tap to zoom.

Another resource: This comparison matrix by Azul Systems is useful, and seems true and fair to my mind.

Here is a list of considerations and motivations to consider in choosing a vendor and implementation.

Some vendors offer you a choice of JIT technologies.

You can open it in a new window with window.open('https://support.wwf.org.uk/earth_hour/index.php?type=individual');. If you want to open it in new tab open the current page in two tabs and then alllow the script to run so that both current page and the new page will be obtained.

I had a similar issue with that. The class name after _OBJC_CLASS_$_ was actually my class. The reason was I didn't tick "Add to Target" when I drag the source code files into navigation list.

My solution was:

1. delete the class from the navigation list and choose "remove reference only"

2. drag the source code files again and make sure the tick box for "add to Target" is ticked. The tick box is just under "Copy if needed" and "Create group".

You can get most of what you want from is_float, but if you really need to know whether it has a decimal in it, your function above isn't terribly far (albeit the wrong language):

function is_decimal( $val )
{
    return is_numeric( $val ) && floor( $val ) != $val;
}

I dont know if the a best solution, but i describe it here:

First of all, you need certificate with you class Application of your app is in your manifest of this:

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

Second, in my class App i did like this:

public class App extends Application {
    public static boolean isOrientationChanged = false;

    @Override
    public void onCreate() {
        super.onCreate();
    }

    @Override
    public void onConfigurationChanged(@NotNull Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE ||
                newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {
            isOrientationChanged = true;
        }
    }

}

Third, you need to set a flag to Orientation Change, in my case, I always set it when the previous activity within the app navigation is called, so only calling once when the later activity is created.

isOrientationChanged = false;

So every time I change the orientation of my screen in that context, I set it every time it changes this setting, it checks if there is a change in orientation, if so, it validates it based on the value of that flag.

Basically, I had to use it whenever I made an asynchronous retrofit request, which he called every moment that changed orientation, constantly crashing the application:

if (!isOrientationChanged) {
    presenter.retrieveAddress(this, idClient, TYPE_ADDRESS);
}

I don't know if it's the most elegant and beautiful solution, but at least here it's functional :)

You need to initialize the list first:

protected List<string> list = new List<string>();

call listView.scheduleLayoutAnimation(); before changing the list

In conf/extra/httpd-vhosts.conf, add the line AllowOverride All for all the websites that you are having problem with

<VirtualHost example.site:80>
    # rest of the stuff
    <Directory "c:\Projects\example.site">
        Require all granted
         AllowOverride All <-----This line is required
    </Directory>
</VirtualHost>

Using target="_blank" will instruct the browser to create a new browser tab or window when the user clicks on the link.

Using target="_new" is technically invalid according to the specifications, but as far as I know every browser will behave the same way:

• it will search for a tab or window with the context name "_new"
• if a "_new" tab/window is found, then the URL is loaded into it
• if it's not found, a new tab/window is created with the context name "_new", and the URL loaded into it

Note target="_new" will behave exactly the same as target="new", and the latter is valid HTML while the former is invalid HTML.

Adding some confusion to this, in HTML4 the target attribute was deprecated. In HTML5 this decision was reversed, and it is an official part of the spec once again. All browsers support target no matter what version of HTML you are using, but some validators will flag the use as deprecated if your doctype is HTML4.

Use table view default property :

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
    return 35.0;
}

Thanks

If you take answer's Shekhar K. Sharma, and it almost work, you need also add to your this height: 1px; or this width: 1px; for must work.

You can use the following code:

startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("sms:"
                        + phoneNumber)));

Make sure you set phoneNumber to the phone number that you want to send the message to

You can add a message to the SMS with (from comments):

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("sms:" + phoneNumber));     
intent.putExtra("sms_body", message); 
startActivity(intent);

This command did the trick from @Aniket Sinha's answer above:

pip install mysqlclient

Use for...in loop:

for (var key in obj) {
   console.log(' name=' + key + ' value=' + obj[key]);

   // do some more stuff with obj[key]
}

The best way to fix this:

Renew the certificate. This can be done for free using Greenlock which issues certificates via Let's Encrypt™ v2

A less insecure way to fix this:

'use strict';

var request = require('request');
var agentOptions;
var agent;

agentOptions = {
  host: 'www.example.com'
, port: '443'
, path: '/'
, rejectUnauthorized: false
};

agent = new https.Agent(agentOptions);

request({
  url: "https://www.example.com/api/endpoint"
, method: 'GET'
, agent: agent
}, function (err, resp, body) {
  // ...
});

By using an agent with rejectUnauthorized you at least limit the security vulnerability to the requests that deal with that one site instead of making your entire node process completely, utterly insecure.

Other Options

If you were using a self-signed cert you would add this option:

agentOptions.ca = [ selfSignedRootCaPemCrtBuffer ];

For trusted-peer connections you would also add these 2 options:

agentOptions.key = clientPemKeyBuffer;
agentOptions.cert = clientPemCrtSignedBySelfSignedRootCaBuffer;

Bad Idea

It's unfortunate that process.env.NODE_TLS_REJECT_UNAUTHORIZED = '0'; is even documented. It should only be used for debugging and should never make it into in sort of code that runs in the wild. Almost every library that runs atop https has a way of passing agent options through. Those that don't should be fixed.

#include <iostrema>

int main(){
    int32_t maxSigned = -1U >> 1;
    cout << maxSigned << '\n';
    return 0;
}

It might be architecture dependent but it does work at least in my setup.

new File(context.getFilesDir(), fileName).delete();

I can delete file in shared preferences with it

In general it's best not to rely on finalize() to do any cleaning up etc.

According to the Javadoc (which it would be worth reading), it is:

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.

As Joachim pointed out, this may never happen in the life of a program if the object is always accessible.

Also, the garbage collector is not guaranteed to run at any specific time. In general, what I'm trying to say is finalize() is probably not the best method to use in general unless there's something specific you need it for.

I just had to revisit this issue today and found Get the source directory of a Bash script from within the script itself:

DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"

There's more variants at the linked answer, e.g. for the case where the script itself is a symlink.

Heres the answer. Gotten from my reddit post... https://www.reddit.com/r/django/comments/6nq0bq/class_question_has_no_objects_member/

That's not an error, it's just a warning from VSC. Django adds that property dynamically to all model classes (it uses a lot of magic under the hood), so the IDE doesn't know about it by looking at the class declaration, so it warns you about a possible error (it's not). objects is in fact a Manager instance that helps with querying the DB. If you really want to get rid of that warning you could go to all your models and add objects = models.Manager() Now, VSC will see the objects declared and will not complain about it again.

I was having a similar problem. (No problems training with GradientDescent optimizer, but error raised when using to Adam Optimizer, or any other optimizer with its own variables)

Changing to an interactive session solved this problem for me.

sess = tf.Session()

into

sess = tf.InteractiveSession()

While you can use the condition && if-true-part || if-false-part-syntax in older versions of angular, the usual ternary operator condition ? true-part : false-part is available in Angular 1.1.5 and later.

You need to load jquery first before bootstrap.

require.config({
    paths: {
        jquery: 'libs/jquery/jquery',
        underscore: 'libs/underscore/underscore',
        backbone: 'libs/backbone/backbone',
        bootstrap: 'libs/bootstrap',
        jquerytablesorter: 'libs/tablesorter/jquery.tablesorter',
        tablesorter: 'libs/tablesorter/tables',
        ajaxupload: 'libs/ajax-upload',
        templates: '../templates'
    },
    shim: {
        'backbone': {
            deps: ['underscore', 'jquery'],
            exports: 'Backbone'
        },
        'jquery': {
            exports: '$'
        },
        'bootstrap': {
            deps: ['jquery'],
            exports: '$'
        },
        'jquerytablesorter': {
            deps: ['jquery'],
            exports: '$'
        },
        'tablesorter': {
            deps: ['jquery'],
            exports: '$'
        },
        'ajaxupload': {
            deps: ['jquery'],
            exports: '$'
        },
        'underscore': {
            exports: '_'
        },
    }
});
require(['app', ], function(App) {
    App.initialize();
});

Works like charm! quick and easy fix.

Answer covering Java >= 9:

For Java 9+, the JVM option needs a slight change by prefixing the address with the IP address of the machine hosting the JVM, or just *:

-agentlib:jdwp=transport=dt_socket,server=y,address=*:8000,suspend=n

This is due to a change noted in https://www.oracle.com/technetwork/java/javase/9-notes-3745703.html#JDK-8041435.

For Java < 9, the port number is enough to connect.

Yes, that is the difference, the Add method throws an exception if the key already exists.

The reason to use the Add method is exactly this. If the dictionary is not supposed to contain the key already, you usually want the exception so that you are made aware of the problem.

Instead of monkey patching or needlessly including large libraries, you can use refinements if you are using Ruby 2:

module HashExtensions
  refine Hash do
    def except!(*candidates)
      candidates.each { |candidate| delete(candidate) }
      self
    end

    def except(*candidates)
      dup.remove!(candidates)
    end
  end
end

You can use this feature without affecting other parts of your program, or having to include large external libraries.

class FabulousCode
  using HashExtensions

  def incredible_stuff
    delightful_hash.except(:not_fabulous_key)
  end
end

I found that JimTheDev's answer only worked when the state definition had cache:false set. With the view cached, you can do $ionicHistory.clearCache() and then $state.go('app.fooDestinationView') if you're navigating from one state to the one that is cached but needs refreshing.

See my answer here as it requires a simple change to Ionic and I created a pull request: https://stackoverflow.com/a/30224972/756177

I came here because I was trying to do the same thing; I knew I had dupes in the source data but only wanted to update the target data and not add the dupes.

I think a MERGE works great here because you can UPDATE or DELETE things that are different and INSERT things that are missing.

I ended up doing this and it worked great. I use SSIS to loop through Excel files and load them into a "RAW" SQL table with dupes and all. Then I run a MERGE to merge the "raw" table with the production table. Then I TRUNCATE the "raw" table and move to the next Excel file.

The most upvoted answers will fail if the file list is too long.

A more portable solution would be using fd

fd -e txt -d 1 -X awk 1 > combined.txt

-d 1 limits the search to the current directory. If you omit this option then it will recursively find all .txt files from the current directory.
-X (otherwise known as --exec-batch) executes a command (awk 1 in this case) for all the search results at once.

To my knowledge the setTimeout function is called asynchronously. What you can do is wrap the entire loop within an async function and await a Promise that contains the setTimeout as shown:

var looper = async function () {
  for (var start = 1; start < 10; start++) {
    await new Promise(function (resolve, reject) {
      setTimeout(function () {
        console.log("iteration: " + start.toString());
        resolve(true);
      }, 1000);
    });
  }
  return true;
}

And then you call run it like so:

looper().then(function(){
  console.log("DONE!")
});

Please take some time to get a good understanding of asynchronous programming.

Tomcat can tell you in several ways. Here's the easiest:

chris            930   0.0  3.1  2987336 258328 s000  S    Wed01PM   2:29.43 /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin/java -Dnop -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.library.path=/usr/local/apache-tomcat-7.0.29/lib -Djava.endorsed.dirs=/usr/local/apache-tomcat-7.0.29/endorsed -classpath /usr/local/apache-tomcat-7.0.29/bin/bootstrap.jar:/usr/local/apache-tomcat-7.0.29/bin/tomcat-juli.jar -Dcatalina.base=/Users/chris/blah/blah -Dcatalina.home=/usr/local/apache-tomcat-7.0.29 -Djava.io.tmpdir=/Users/chris/blah/blah/temp org.apache.catalina.startup.Bootstrap start

From the ps output, you can see both catalina.home and catalina.base. catalina.home is where the Tomcat base files are installed, and catalina.base is where the running configuration of Tomcat exists. These are often set to the same value unless you have configured your Tomcat for multiple (configuration) instances to be launched from a single Tomcat base install.

You can also interrogate the JVM directly if you can't find it in a ps listing:

$ jinfo -sysprops 930 | grep catalina
Attaching to process ID 930, please wait...
Debugger attached successfully.
Server compiler detected.
JVM version is 20.8-b03-424
catalina.base = /Users/chris/blah/blah
[...]
catalina.home = /usr/local/apache-tomcat-7.0.29

If you can't manage that, you can always try to write a JSP that dumps the values of the two system properties catalina.home and catalina.base.

So to recap your question: you want to avoid, as much as possible, trouble with the IE6 GC bug. That bug has two causes:

1. Garbage Collection occurs once every so many allocations; therefore, the more allocations you make, the oftener GC will run;
2. The more objects you've got ‘in the air’, the more time each Garbage Collection run takes (since it'll crawl through the entire list of objects to see which are marked as garbage).

The solution to cause 1 seems to be: keep the number of allocations down; assign new objects and strings as little as possible.

The solution to cause 2 seems to be: keep the number of 'live' objects down; delete your strings and objects as soon as you don't need them anymore, and create them afresh when necessary.

To a certain extent, these solutions are contradictory: to keep the number of objects in memory low will entail more allocations and de-allocations. Conversely, constantly reusing the same objects could mean keeping more objects in memory than strictly necessary.

Now for your question. Whether you'll reset an object by creating a new one, or by deleting all its properties: that will depend on what you want to do with it afterwards.

You’ll probably want to assign new properties to it:

• If you do so immediately, then I suggest assigning the new properties straightaway, and skip deleting or clearing first. (Make sure that all properties are either overwritten or deleted, though!)
• If the object won't be used immediately, but will be repopulated at some later stage, then I suggest deleting it or assigning it null, and create a new one later on.

There's no fast, easy to use way to clear a JScript object for reuse as if it were a new object — without creating a new one. Which means the short answer to your question is ‘No’, like jthompson says.
