Mmhh I know you've already discarded URLEncoder, but despite of what the docs say, I decided to give it a try.

You said:

For example, given an input:

http://google.com/resource?key=value

I expect the output:

http%3a%2f%2fgoogle.com%2fresource%3fkey%3dvalue

So:

C:\oreyes\samples\java\URL>type URLEncodeSample.java
import java.net.*;

public class URLEncodeSample {
    public static void main( String [] args ) throws Throwable {
        System.out.println( URLEncoder.encode( args[0], "UTF-8" ));
    }
}

C:\oreyes\samples\java\URL>javac URLEncodeSample.java

C:\oreyes\samples\java\URL>java URLEncodeSample "http://google.com/resource?key=value"
http%3A%2F%2Fgoogle.com%2Fresource%3Fkey%3Dvalue

As expected.

What would be the problem with this?

Worked for me,

select lcase((insert( insert( insert( insert(hex(BLOB_FIELD),9,0,'-'), 14,0,'-'), 19,0,'-'), 24,0,'-'))) as FIELD_ID from TABLE_WITH_BLOB where ID = 'row id';

for me anyways, it helps to see it used. just made this using the "re" example:

var analyte_data = 'sample-'+sample_id;
var storage_keys = $.jStorage.index();
var re = new RegExp( analyte_data,'g');  
for(i=0;i<storage_keys.length;i++) { 
    if(storage_keys[i].match(re)) {
        console.log(storage_keys[i]);
        var partnum = storage_keys[i].split('-')[2];
    }
}

Meteor's strength is in it's real-time updates feature which works well for some of the social applications you see nowadays where you see everyone's updates for what you're working on. These updates center around replicating subsets of a MongoDB collection underneath the covers as local mini-mongo (their client side MongoDB subset) database updates on your web browser (which causes multiple render events to be fired on your templates). The latter part about multiple render updates is also the weakness. If you want your UI to control when the UI refreshes (e.g., classic jQuery AJAX pages where you load up the HTML and you control all the AJAX calls and UI updates), you'll be fighting this mechanism.

Meteor uses a nice stack of Node.js plugins (Handlebars.js, Spark.js, Bootstrap css, etc. but using it's own packaging mechanism instead of npm) underneath along w/ MongoDB for the storage layer that you don't have to think about. But sometimes you end up fighting it as well...e.g., if you want to customize the Bootstrap theme, it messes up the loading sequence of Bootstrap's responsive.css file so it no longer is responsive (but this will probably fix itself when Bootstrap 3.0 is released soon).

So like all "full stack frameworks", things work great as long as your app fits what's intended. Once you go beyond that scope and push the edge boundaries, you might end up fighting the framework...

A simple solution, in pure single SQL. You get the idea, you may extend it to more attributes you like to show.

with c as (
SELECT table_name, ordinal_position, 
 column_name|| ' ' || data_type col
, row_number() over (partition by table_name order by ordinal_position asc) rn
, count(*) over (partition by table_name) cnt
FROM information_schema.columns
WHERE table_name   in ('pg_index', 'pg_tables')
order by table_name, ordinal_position
)
select case when rn = 1 then 'create table ' || table_name || '(' else '' end
 || col 
 || case when rn < cnt then ',' else '); ' end
from c 
order by table_name, rn asc;

Output:

create table pg_index(indexrelid oid,
 indrelid oid,
 indnatts smallint,
 indisunique boolean,
 indisprimary boolean,
 indisexclusion boolean,
 indimmediate boolean,
 indisclustered boolean,
 indisvalid boolean,
 indcheckxmin boolean,
 indisready boolean,
 indislive boolean,
 indisreplident boolean,
 indkey ARRAY,
 indcollation ARRAY,
 indclass ARRAY,
 indoption ARRAY,
 indexprs pg_node_tree,
 indpred pg_node_tree);

 create table pg_tables(schemaname name,
 tablename name,
 tableowner name,
 tablespace name,
 hasindexes boolean,
 hasrules boolean,
 hastriggers boolean,
 rowsecurity boolean);

len(myList) should do it.

len works with all the collections, and strings too.

If you know the aspect ratio for example, if your image is square you can set either the height or the width to fill the container and get the other to be set by the aspectRatio property

Here is the style if you want the height be set automatically:

{
    width: '100%',
    height: undefined,
    aspectRatio: 1,
}

Note: height must be undefined

After spending much time searching for a response to this answer: how to download a simple image from my API restful server written in Node.js into an Angular component app, I finally found a beautiful answer in this web Angular HttpClient Blob. Essentially it consist on:

API Node.js restful:

   /* After routing the path you want ..*/
  public getImage( req: Request, res: Response) {

    // Check if file exist...
    if (!req.params.file) {
      return res.status(httpStatus.badRequest).json({
        ok: false,
        msg: 'File param not found.'
      })
    }
    const absfile = path.join(STORE_ROOT_DIR,IMAGES_DIR, req.params.file);

    if (!fs.existsSync(absfile)) {
      return res.status(httpStatus.badRequest).json({
        ok: false,
        msg: 'File name not found on server.'
      })
    }
    res.sendFile(path.resolve(absfile));
  }

Angular 6 tested component service (EmployeeService on my case):

  downloadPhoto( name: string) : Observable<Blob> {
    const url = environment.api_url + '/storer/employee/image/' + name;

    return this.http.get(url, { responseType: 'blob' })
      .pipe(
        takeWhile( () => this.alive),
        filter ( image => !!image));
  }

Template

 <img [src]="" class="custom-photo" #photo>

Component subscriber and use:

@ViewChild('photo') image: ElementRef;

public LoadPhoto( name: string) {
    this._employeeService.downloadPhoto(name)
          .subscribe( image => {
            const url= window.URL.createObjectURL(image);
            this.image.nativeElement.src= url;
          }, error => {
            console.log('error downloading: ', error);
          })    
}

Consider a example where I have two databases namely allmsa.db and atlanta.db. Say the database allmsa.db has tables for all msas in US and database atlanta.db is empty.

Our target is to copy the table atlanta from allmsa.db to atlanta.db.

Steps

1. sqlite3 atlanta.db(to go into atlanta database)
2. Attach allmsa.db. This can be done using the command ATTACH '/mnt/fastaccessDS/core/csv/allmsa.db' AS AM; note that we give the entire path of the database to be attached.
3. check the database list using sqlite> .databases you can see the output as

seq  name             file                                                      
---  ---------------  ----------------------------------------------------------
0    main             /mnt/fastaccessDS/core/csv/atlanta.db                  
2    AM               /mnt/fastaccessDS/core/csv/allmsa.db 

4. now you come to your actual target. Use the command INSERT INTO atlanta SELECT * FROM AM.atlanta;

This should serve your purpose.

Edit: Passing the operator as a reference doesnt work. For simplicity, understand it as a function pointer. You just send the pointer, not a reference. I think you are trying to write something like this.

struct Square
{
    double operator()(double number) { return number * number; }
};

template <class Function>
double integrate(Function f, double a, double b, unsigned int intervals)
{
    double delta = (b - a) / intervals, sum = 0.0;

    while(a < b)
    {
        sum += f(a) * delta;
        a += delta;
    }

    return sum;
}

. .

std::cout << "interval : " << i << tab << tab << "intgeration = "
 << integrate(Square(), 0.0, 1.0, 10) << std::endl;

Initializing a vector having struct, class or Union can be done this way

std::vector<SomeStruct> someStructVect(length);
memset(someStructVect.data(), 0, sizeof(SomeStruct)*length);

I just do it like this:

CvCapture *capture = cvCreateFileCapture("rtsp://camera-address");

Also make sure this dll is available at runtime else cvCreateFileCapture will return NULL

opencv_ffmpeg200d.dll

The camera needs to allow unauthenticated access too, usually set via its web interface. MJPEG format worked via rtsp but MPEG4 didn't.

In case you're using the option stream=True you can do this:

r = requests.get(
    'http://url_to_large_file',
    timeout=1,  # relevant only for underlying socket
    stream=True)

with open('/tmp/out_file.txt'), 'wb') as f:
    start_time = time.time()
    for chunk in r.iter_content(chunk_size=1024):
        if chunk:  # filter out keep-alive new chunks
            f.write(chunk)
        if time.time() - start_time > 8:
            raise Exception('Request took longer than 8s')

The solution does not need signals or multiprocessing.

No, you cannot set them all in a single statement.
At the general case, you need at least three properties:

border-color: red green white blue;
border-style: solid dashed dotted solid;
border-width: 1px 2px 3px 4px;

However, that would be quite messy. It would be more readable and maintainable with four:

border-top:    1px solid  #ff0;
border-right:  2px dashed #f0F;
border-bottom: 3px dotted #f00;
border-left:   5px solid  #09f;

For more complex DataFrames that have a Multi-Index (say "Stock" and "Date") and one wants to remove the last row for each Stock not just the last row of the last Stock, then the solution reads:

# To remove last n rows
df = df.groupby(level='Stock').apply(lambda x: x.head(-1)).reset_index(0, drop=True)

# To remove first n rows
df = df.groupby(level='Stock').apply(lambda x: x.tail(-1)).reset_index(0, drop=True)

As the groupby() is adding an additional level to the Multi-Index we just drop it at the end using reset_index(). The resulting df keeps the same type of Multi-Index as before the operation.

Let us consider a table which stores the shift details

Please check the SQL queries to generate table and finding the schedule based on an input(time)

Declaring the Table variable

declare @MyShiftTable table(MyShift int,StartTime time,EndTime time)

Adding values to Table variable

insert into @MyShiftTable select 1,'01:17:40.3530000','02:17:40.3530000'
insert into @MyShiftTable select 2,'09:17:40.3530000','03:17:40.3530000'
insert into @MyShiftTable select 3,'10:17:40.3530000','18:17:40.3530000'

Creating another table variable with an additional field named "Flag"

declare @Temp table(MyShift int,StartTime time,EndTime time,Flag int)

Adding values to temporary table with swapping the start and end time

insert into @Temp select MyShift,case when (StartTime>EndTime) then EndTime else StartTime end,case when (StartTime>EndTime) then StartTime else EndTime end,case when (StartTime>EndTime) then 1 else 0 end from @MyShiftTable

Creating input variable to find the Shift

declare @time time=convert(time,'10:12:40.3530000')

Query to find the shift corresponding to the time supplied

select myShift from @Temp where
(@time between StartTime and EndTime and Flag=0) or (@time not between StartTime and EndTime and Flag=1)

You can also try using runuser (as root) to run a command as a different user

*/1 * * * * runuser php5 \
            --command="/var/www/web/includes/crontab/queue_process.php \
                       >> /var/www/web/includes/crontab/queue.log 2>&1"

See also: man runuser

So I was looking all over for a way to remove all files in a directory except for some directories, and files, I wanted to keep around. After much searching I devised a way to do it using find.

find -E . -regex './(dir1|dir2|dir3)' -and -type d -prune -o -print -exec rm -rf {} \;

Essentially it uses regex to select the directories to exclude from the results then removes the remaining files. Just wanted to put it out here in case someone else needed it.

Constructing a new dict:

dict_you_want = { your_key: old_dict[your_key] for your_key in your_keys }

Uses dictionary comprehension.

If you use a version which lacks them (ie Python 2.6 and earlier), make it dict((your_key, old_dict[your_key]) for ...). It's the same, though uglier.

Note that this, unlike jnnnnn's version, has stable performance (depends only on number of your_keys) for old_dicts of any size. Both in terms of speed and memory. Since this is a generator expression, it processes one item at a time, and it doesn't looks through all items of old_dict.

Removing everything in-place:

unwanted = set(keys) - set(your_dict)
for unwanted_key in unwanted: del your_dict[unwanted_key]

For lamdas where your long value is somewhere in an object I recommend using:

.sorted((o1, o2) -> Long.compare(o1.getLong(), o2.getLong()))

or even better:

.sorted(Comparator.comparingLong(MyObject::getLong))

Create a new datafile by running the following command:

alter tablespace TABLE_SPACE_NAME add datafile 'D:\oracle\Oradata\TEMP04.dbf'            
   size 2000M autoextend on;

Sure you can use isinstance, but be aware that this is not how Python works. Python is a duck typed language. You should not explicitly check your types. A TypeError will be raised if the incorrect type was passed.

So just assume it is an int. Don't bother checking.

$sUrl = 'http://www.linktopage.com/login/';
$params = array('http' => array(
    'method'  => 'POST',
    'content' => 'username=admin195&password=d123456789'
));

$ctx = stream_context_create($params);
$fp = @fopen($sUrl, 'rb', false, $ctx);
if(!$fp) {
    throw new Exception("Problem with $sUrl, $php_errormsg");
}

$response = @stream_get_contents($fp);
if($response === false) {
    throw new Exception("Problem reading data from $sUrl, $php_errormsg");
}

Try

SELECT li.clientid, group_concat(li.views ORDER BY li.views) AS views,
       group_concat(li.percentage ORDER BY li.percentage) 
FROM table_views li 
GROUP BY client_id

http://dev.mysql.com/doc/refman/5.0/en/group-by-functions.html#function%5Fgroup-concat

Try this instead:

print_r($sth->errorInfo());

Add this before your prepare:

$this->pdo->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING );

This will change the PDO error reporting type and cause it to emit a warning whenever there is a PDO error. It should help you track it down, although your errorInfo should have bet set.

If the file contains only parameter assignments, you can use the following loop in place of sourcing it:

# Instead of source file.txt
while IFS="=" read name value; do
    declare "$name=$value"
done < file.txt

This saves you having to quote anything in the file, and is also more secure, as you don't risk executing arbitrary code from file.txt.

Above answers are great, but as jquery evolves.. so you can also do:

var myId = $("#test").prop("id");

I had a similar problem when I needed to make multiple sql queries. The problem was that some queries did not return the result and I wanted to print that result. And there was a mistake. As already written, there are several solutions.

if cursor.description is None:
    # No recordset for INSERT, UPDATE, CREATE, etc
    pass
else:
    # Recordset for SELECT

As well as:

exist = cursor.fetchone()
if exist is None:
  ... # does not exist
else:
  ... # exists

One of the solutions is:

The try and except block lets you handle the error/exceptions. The finally block lets you execute code, regardless of the result of the try and except blocks. So the presented problem can be solved by using it.

s = """ set current query acceleration = enable;
        set current GET_ACCEL_ARCHIVE = yes;
        SELECT * FROM TABLE_NAME;"""

query_sqls = [i.strip() + ";" for i in filter(None, s.split(';'))]
for sql in query_sqls:
    print(f"Executing SQL statements ====> {sql} <=====")
    cursor.execute(sql)
    print(f"SQL ====> {sql} <===== was executed successfully")
    try:
        print("\n****************** RESULT ***********************")
        for result in cursor.fetchall():
            print(result)
        print("****************** END RESULT ***********************\n")
    except Exception as e:
        print(f"SQL: ====> {sql} <==== doesn't have output!\n")
        # print(str(e))

output:

Executing SQL statements ====> set current query acceleration = enable; <=====
SQL: ====> set current query acceleration = enable; <==== doesn't have output!

Executing SQL statements ====> set current GET_ACCEL_ARCHIVE = yes; <=====
SQL: ====> set current GET_ACCEL_ARCHIVE = yes; <==== doesn't have output!

Executing SQL statements ====> SELECT * FROM TABLE_NAME; <=====

****************** RESULT ***********************

       ----------   DATA   ----------

****************** END RESULT ***********************

The example above only presents a simple use as an idea that could help with your solution. Of course, you should also pay attention to other errors, such as the correctness of the query, etc.

Locations are evaluated in this order:

1. location = /path/file.ext {} Exact match
2. location ^~ /path/ {} Priority prefix match -> longest first
3. location ~ /Paths?/ {} (case-sensitive regexp) and location ~* /paths?/ {} (case-insensitive regexp) -> first match
4. location /path/ {} Prefix match -> longest first

The priority prefix match (number 2) is exactly as the common prefix match (number 4), but has priority over any regexp.

For both prefix matche types the longest match wins.

Case-sensitive and case-insensitive have the same priority. Evaluation stops at the first matching rule.

Documentation says that all prefix rules are evaluated before any regexp, but if one regexp matches then no standard prefix rule is used. That's a little bit confusing and does not change anything for the priority order reported above.

I have been working on Swagger equivalent documentation library called Springfox nowadays and I found that in the Spring 5.0.8 (running at present), interface WebMvcConfigurer has been implemented by class WebMvcConfigurationSupport class which we can directly extend.

import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;

public class WebConfig extends WebMvcConfigurationSupport { }

And this is how I have used it for setting my resource handling mechanism as follows -

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("swagger-ui.html")
            .addResourceLocations("classpath:/META-INF/resources/");

    registry.addResourceHandler("/webjars/**")
            .addResourceLocations("classpath:/META-INF/resources/webjars/");
}

You could create a canvas (via javascript) and draw a dotted line within. Within the canvas you can control how long the dash and the space in between shall be.

This esc behavior is IE only by the way. Instead of using jQuery use good old javascript for creating the element and it works.

var element = document.createElement('input');
element.type = 'text';
element.value = 100;
document.getElementsByTagName('body')[0].appendChild(element);

http://jsfiddle.net/gGrf9/

If you want to extend this functionality to other browsers then I would use jQuery's data object to store the default. Then set it when user presses escape.

//store default value for all elements on page. set new default on blur
$('input').each( function() {
    $(this).data('default', $(this).val());
    $(this).blur( function() { $(this).data('default', $(this).val()); });
});

$('input').keyup( function(e) {
    if (e.keyCode == 27) { $(this).val($(this).data('default')); }
});

The following code works for me.

//escape the double quotes in json string
String payload="{\"jsonrpc\":\"2.0\",\"method\":\"changeDetail\",\"params\":[{\"id\":11376}],\"id\":2}";
String requestUrl="https://git.eclipse.org/r/gerrit/rpc/ChangeDetailService";
sendPostRequest(requestUrl, payload);

method implementation:

public static String sendPostRequest(String requestUrl, String payload) {
    try {
        URL url = new URL(requestUrl);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();

        connection.setDoInput(true);
        connection.setDoOutput(true);
        connection.setRequestMethod("POST");
        connection.setRequestProperty("Accept", "application/json");
        connection.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
        OutputStreamWriter writer = new OutputStreamWriter(connection.getOutputStream(), "UTF-8");
        writer.write(payload);
        writer.close();
        BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream()));
        StringBuffer jsonString = new StringBuffer();
        String line;
        while ((line = br.readLine()) != null) {
                jsonString.append(line);
        }
        br.close();
        connection.disconnect();
        return jsonString.toString();
    } catch (Exception e) {
            throw new RuntimeException(e.getMessage());
    }

}

I have a gradle project and when my build.gradle dependencies section looks like this:

dependencies {
    implementation group: 'org.apache.commons', name: 'commons-lang3', version: '3.8.1'

    testImplementation group: 'org.mockito', name: 'mockito-all', version: '1.10.19'
    testImplementation 'junit:junit:4.12'
//    testCompile group: 'org.mockito', name: 'mockito-core', version: '2.23.4'

    compileOnly 'org.projectlombok:lombok:1.18.4'
    apt 'org.projectlombok:lombok:1.18.4'
}

it leads to this exception:

java.lang.NoSuchMethodError: org.hamcrest.Matcher.describeMismatch(Ljava/lang/Object;Lorg/hamcrest/Description;)V

    at org.hamcrest.MatcherAssert.assertThat(MatcherAssert.java:18)
    at org.hamcrest.MatcherAssert.assertThat(MatcherAssert.java:8)

to fix this issue, I've substituted "mockito-all" with "mockito-core".

dependencies {
    implementation group: 'org.apache.commons', name: 'commons-lang3', version: '3.8.1'

//    testImplementation group: 'org.mockito', name: 'mockito-all', version: '1.10.19'

    compileOnly 'org.projectlombok:lombok:1.18.4'
    apt 'org.projectlombok:lombok:1.18.4'

The explanation between mockito-all and mockito-core can be found here: https://solidsoft.wordpress.com/2012/09/11/beyond-the-mockito-refcard-part-3-mockito-core-vs-mockito-all-in-mavengradle-based-projects/

mockito-all.jar besides Mockito itself contains also (as of 1.9.5) two dependencies: Hamcrest and Objenesis (let’s omit repackaged ASM and CGLIB for a moment). The reason was to have everything what is needed inside an one JAR to just put it on a classpath. It can look strange, but please remember than Mockito development started in times when pure Ant (without dependency management) was the most popular build system for Java projects and the all external JARs required by a project (i.e. our project’s dependencies and their dependencies) had to be downloaded manually and specified in a build script.

On the other hand mockito-core.jar is just Mockito classes (also with repackaged ASM and CGLIB). When using it with Maven or Gradle required dependencies (Hamcrest and Objenesis) are managed by those tools (downloaded automatically and put on a test classpath). It allows to override used versions (for example if our projects uses never, but backward compatible version), but what is more important those dependencies are not hidden inside mockito-all.jar what allows to detected possible version incompatibility with dependency analyze tools. This is much better solution when dependency managed tool is used in a project.

One solution is to put them inside <center>, like this:

Use String#replace().

To replace them with spaces (as per your question title):

System.out.println("I don't like these \"double\" quotes".replace("\"", " "));

The above can also be done with characters:

System.out.println("I don't like these \"double\" quotes".replace('"', ' '));

To remove them (as per your example):

System.out.println("I don't like these \"double\" quotes".replace("\"", ""));

This following code is enough

RecyclerView recyclerView;
LinearLayoutManager layoutManager = new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL,true);

 recyclerView.setLayoutManager(layoutManager);

Add overflow: auto to the container div. http://www.quirksmode.org/css/clearing.html This website shows a few options when having this issue.

List<Integer>[] array;  
array = new List<Integer>[10]; 

this the second case in @TofuBeer's answer is incorrect. because can't create arrays with generics. u can use:

List<List<Integer>> array = new ArrayList<>();

Installing just vcredist_x64.exe from Visual C++ Redistributable for Visual Studio 2012 fixed the issue for me.

I'm using Windows 7 Home Basic 64 bit and installed WampServer 2.5

I am using blueJ for java programming. There is a way to clear the screen of it's terminal window. Try this:-

System.out.print ('\f');

this will clear whatever is printed before this line. But this does not work in command prompt.

Two ways to implement a Caesar Cipher:

Option 1: Change chars to ASCII numbers, then you can increase the value, then revert it back to the new character.

Option 2: Use a Map map each letter to a digit like this.

A - 0
B - 1
C - 2
etc...

With a map you don't have to re-calculate the shift every time. Then you can change to and from plaintext to encrypted by following map.

On macOS, the reason for using the --user flag is to make sure we don't corrupt the libraries the OS relies on. A conservative approach for many macOS users is to avoid installing or updating pip with a command that requires sudo. Thus, this includes installing to /usr/local/bin...

Ref: Installing python for Neovim (https://github.com/zchee/deoplete-jedi/wiki/Setting-up-Python-for-Neovim)

I'm not all clear why installing into /usr/local/bin is a risk on a Mac given the fact that the system only relies on python binaries in /Library/Frameworks/ and /usr/bin. I suspect it's because as noted above, installing into /usr/local/bin requires sudo which opens the door to making a costly mistake with the system libraries. Thus, installing into ~/.local/bin is a sure fire way to avoid this risk.

Ref: Using python on a Mac (https://docs.python.org/2/using/mac.html)

Finally, to the degree there is a benefit of installing packages into the /usr/local/bin, I wonder if it makes sense to change the owner of the directory from root to user? This would avoid having to use sudo while still protecting against making system-dependent changes.* Is this a security default a relic of how Unix systems were more often used in the past (as servers)? Or at minimum, just a good way to go for Mac users not hosting a server?

*Note: Mac's System Integrity Protection (SIP) feature also seems to protect the user from changing the system-dependent libraries.

Assignment expressions from PEP 572 (new in Python 3.8) offer yet another way to solve this:

time_interval = [4, 6, 12]

total_time = 0
cum_time = [total_time := total_time + t for t in time_interval]

From the documentation:

contentType (default: 'application/x-www-form-urlencoded; charset=UTF-8')

Type: String

When sending data to the server, use this content type. Default is "application/x-www-form-urlencoded; charset=UTF-8", which is fine for most cases. If you explicitly pass in a content-type to $.ajax(), then it'll always be sent to the server (even if no data is sent). If no charset is specified, data will be transmitted to the server using the server's default charset; you must decode this appropriately on the server side.

and:

dataType (default: Intelligent Guess (xml, json, script, or html))

Type: String

The type of data that you're expecting back from the server. If none is specified, jQuery will try to infer it based on the MIME type of the response (an XML MIME type will yield XML, in 1.4 JSON will yield a JavaScript object, in 1.4 script will execute the script, and anything else will be returned as a string).

They're essentially the opposite of what you thought they were.

This happened to me when I was experimenting with Maven.

Right click project -> Maven -> disable maven nature corrected the problem for me.

You can just use padding. Like so:

http://jsfiddle.net/davidja/KG8Kv/

HTML

   <table>
        <tr>
            <td>item1</td>
            <td>item2</td>
            <td>item2</td>
        </tr>
    </table>

CSS

 td {padding:10px 25px 10px 25px;}

OR

 tr td:first-child {padding-left:0px;}
 td {padding:10px 0px 10px 50px;}

This promise will not resolve if the argument of JSON.parse() can not be parsed into a JSON object.

Promise.resolve(JSON.parse('{"key":"value"}')).then(json => {
    console.log(json);
}).catch(err => {
    console.log(err);
});

I took the JAXB.marshal implementation and added jaxb.fragment=true to remove the XML prolog. This method can handle objects even without the XmlRootElement annotation. This also throws the unchecked DataBindingException.

public static String toXmlString(Object o) {
    try {
        Class<?> clazz = o.getClass();
        JAXBContext context = JAXBContext.newInstance(clazz);
        Marshaller marshaller = context.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FRAGMENT, true); // remove xml prolog
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true); // formatted output

        final QName name = new QName(Introspector.decapitalize(clazz.getSimpleName()));
        JAXBElement jaxbElement = new JAXBElement(name, clazz, o);

        StringWriter sw = new StringWriter();
        marshaller.marshal(jaxbElement, sw);
        return sw.toString();

    } catch (JAXBException e) {
        throw new DataBindingException(e);
    }
}

If the compiler warning bothers you, here's the templated, two parameter version.

public static <T> String toXmlString(T o, Class<T> clazz) {
    try {
        JAXBContext context = JAXBContext.newInstance(clazz);
        Marshaller marshaller = context.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FRAGMENT, true); // remove xml prolog
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true); // formatted output

        QName name = new QName(Introspector.decapitalize(clazz.getSimpleName()));
        JAXBElement jaxbElement = new JAXBElement<>(name, clazz, o);

        StringWriter sw = new StringWriter();
        marshaller.marshal(jaxbElement, sw);
        return sw.toString();

    } catch (JAXBException e) {
        throw new DataBindingException(e);
    }
}

Since I spent quite some time trying to solve this and always came back to this page when looking for this error, I'll leave my solution here hoping that somebody saves the time I've lost. Although in my case I am using mariadb rather than MySql, you might still be able to adapt this solution to your needs.

My problem

is the same, but my setup is a bit different (mariadb instead of mysql):

Installed mariadb with homebrew

$ brew install mariadb

Started the daemon

$ brew services start mariadb

Tried to connect and got the above mentioned error

$ mysql -uroot
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

My solution

find out which my.cnf files are used by mysql (as suggested in this comment):

$ mysql --verbose --help | grep my.cnf
/usr/local/etc/my.cnf ~/.my.cnf
                        order of preference, my.cnf, $MYSQL_TCP_PORT,

check where the Unix socket file is running (almost as described here):

$ netstat -ln | grep mariadb
.... /usr/local/mariadb/data/mariadb.sock

(you might want to grep mysql instead of mariadb)

Add the socket file you found to ~/.my.cnf (create the file if necessary)(assuming ~/.my.cnf was listed when running the mysql --verbose ...-command from above):

[client]
socket = /usr/local/mariadb/data/mariadb.sock

Restart your mariadb:

$ brew services restart mariadb

After this I could run mysql and got:

$ mysql -uroot
ERROR 1698 (28000): Access denied for user 'root'@'localhost'

So I run the command with superuser privileges instead and after entering my password I got:

$ sudo mysql -uroot
MariaDB [(none)]>

Notes:

1. I'm not quite sure about the groups where you have to add the socket, first I had it [client-server] but then I figured [client] should be enough. So I changed it and it still works.

2. When running mariadb_config | grep socket I get: --socket [/tmp/mysql.sock] which is a bit confusing since it seems that /usr/local/mariadb/data/mariadb.sock is the actual place (at least on my machine)

3. I wonder where I can configure the /usr/local/mariadb/data/mariadb.sock to actually be /tmp/mysql.sockso I can use the default settings instead of having to edit my .my.cnf (but I'm too tired now to figure that out...)

4. At some point I also did things mentioned in other answers before coming up with this.

1. Find the path from error log and open the file in explorer 2)select the file and right-click -> properties
2. Then check the 'unblock' option and click on apply

Replace measureScrapChild to follow code:

private void measureScrapChild(RecyclerView.Recycler recycler, int position, int widthSpec,
        int heightSpec, int[] measuredDimension)
    {
        View view = recycler.GetViewForPosition(position);
        if (view != null)
        {
            MeasureChildWithMargins(view, widthSpec, heightSpec);
            measuredDimension[0] = view.MeasuredWidth;
            measuredDimension[1] = view.MeasuredHeight;
            recycler.RecycleView(view);
        }
    }

I use xamarin, so this is c# code. I think this can be easily "translated" to Java.

{0: 'Hi', 1: 'I', 2: 'am', 3: 'John'}

Android Studio 3

The answers that talk about Maven Central are dated since Android Studio uses JCenter as the default repository center now. Your project's build.gradle file should have something like this:

repositories {
    google()
    jcenter()
}

So as long as the developer has their Maven repository there (which Picasso does), then all you would have to do is add a single line to the dependencies section of your app's build.gradle file.

dependencies {
    // ...
    implementation 'com.squareup.picasso:picasso:2.5.2'
}

I tried to change target sdk to 13 but does not works!! then when I changed compileSdkVersion 13 to compileSdkVersion 14 is compiled successfully :)

NOTE: I Work with Android Studio not Eclipse

Java documentation is helpful to know the root cause of a particular IOException.

Just have a look at the direct known sub-interfaces of IOException from the documentation page:

ChangedCharSetException, CharacterCodingException, CharConversionException, ClosedChannelException, EOFException, FileLockInterruptionException, FileNotFoundException, FilerException, FileSystemException, HttpRetryException, IIOException, InterruptedByTimeoutException, InterruptedIOException, InvalidPropertiesFormatException, JMXProviderException, JMXServerErrorException, MalformedURLException, ObjectStreamException, ProtocolException, RemoteException, SaslException, SocketException, SSLException, SyncFailedException, UnknownHostException, UnknownServiceException, UnsupportedDataTypeException, UnsupportedEncodingException, UserPrincipalNotFoundException, UTFDataFormatException, ZipException

Most of these exceptions are self-explanatory.

A few IOExceptions with root causes:

EOFException: Signals that an end of file or end of stream has been reached unexpectedly during input. This exception is mainly used by data input streams to signal the end of the stream.

SocketException: Thrown to indicate that there is an error creating or accessing a Socket.

RemoteException: A RemoteException is the common superclass for a number of communication-related exceptions that may occur during the execution of a remote method call. Each method of a remote interface, an interface that extends java.rmi.Remote, must list RemoteException in its throws clause.

UnknownHostException: Thrown to indicate that the IP address of a host could not be determined (you may not be connected to Internet).

MalformedURLException: Thrown to indicate that a malformed URL has occurred. Either no legal protocol could be found in a specification string or the string could not be parsed.

There are many ways of doing it, I'm listing a few here:

1. Use SizedBox if you want to set some specific space

   Row(
     children: <Widget>[
       Text("1"),
       SizedBox(width: 50), // give it width
       Text("2"),
     ],
   )
   

   

2. Use Spacer if you want both to be as far apart as possible.

   Row(
     children: <Widget>[
       Text("1"),
       Spacer(), // use Spacer
       Text("2"),
     ],
   )
   

   

3. Use mainAxisAlignment according to your needs:

   Row(
     mainAxisAlignment: MainAxisAlignment.spaceEvenly, // use whichever suits your need
     children: <Widget>[
       Text("1"),
       Text("2"),
     ],
   )
   

   

4. Use Wrap instead of Row and give some spacing

   Wrap(
     spacing: 100, // set spacing here
     children: <Widget>[
       Text("1"),
       Text("2"),
     ],
   )
   

   

5. Use Wrap instead of Row and give it alignment

   Wrap(
     alignment: WrapAlignment.spaceAround, // set your alignment
     children: <Widget>[
       Text("1"),
       Text("2"),
     ],
   )
   

   

Not ISO-8601 week number but if the search engine pointed you here anyways.

As said above but without a class:

let now = new Date();
let onejan = new Date(now.getFullYear(), 0, 1);
let week = Math.ceil( (((now.getTime() - onejan.getTime()) / 86400000) + onejan.getDay() + 1) / 7 );

<button style="position: absolute; left: 20%; right: 20%; bottom: 5%;"> Button </button>

Legibility/cognitive load preference

To me, the main gain is that I only need to remember, and read, one form of the complicated regex API syntax - the <compiled_pattern>.method(xxx) form rather than that and the re.func(<pattern>, xxx) form.

The re.compile(<pattern>) is a bit of extra boilerplate, true.

But where regex are concerned, that extra compile step is unlikely to be a big cause of cognitive load. And in fact, on complicated patterns, you might even gain clarity from separating the declaration from whatever regex method you then invoke on it.

I tend to first tune complicated patterns in a website like Regex101, or even in a separate minimal test script, then bring them into my code, so separating the declaration from its use fits my workflow as well.

For those who searches for an answer without parsing and loosing milliseconds, given dt_obj is a datetime:

python3 only, elegant

int(dt_obj.timestamp() * 1000)

both python2 and python3 compatible:

import time

int(time.mktime(dt_obj.utctimetuple()) * 1000 + dt_obj.microsecond / 1000)

If you would like to write your own, you can start with this six-part document detailing effective usage of C# 2.0 data structures and how to go about analyzing your implementation of data structures in C#. Each article has examples and an installer with samples you can follow along with.

var res = function(str){
    var ob; var oe;
    for(var i = 0; i < str.length; i++){
        if(str.charAt(i) != " " && ob == undefined){ob = i;}
        if(str.charAt(i) != " "){oe = i;}
    }
    return str.substring(ob,oe+1);
}

@Steve Morgan and @Richard Gourlay this is a great solution, thank you for that. One small drawback is that when the number of bytes in a file is 255 or below, the mime type will sometimes yield "application/octet-stream", which is slightly inaccurate for files which would be expected to yield "text/plain". I have updated your original method to account for this situation as follows:

If the number of bytes in the file is less than or equal to 255 and the deduced mime type is "application/octet-stream", then create a new byte array that consists of the original file bytes repeated n-times until the total number of bytes is >= 256. Then re-check the mime-type on that new byte array.

When you open a file, the system points to the beginning of the file. Any read or write you do will happen from the beginning. A seek() operation moves that pointer to some other part of the file so you can read or write at that place.

So, if you want to read the whole file but skip the first 20 bytes, open the file, seek(20) to move to where you want to start reading, then continue with reading the file.

Or say you want to read every 10th byte, you could write a loop that does seek(9, 1) (moves 9 bytes forward relative to the current positions), read(1) (reads one byte), repeat.

The PropTypes documentation has the following

// Anything that can be rendered: numbers, strings, elements or an array
// (or fragment) containing these types.
optionalNode: PropTypes.node,

So, you can use PropTypes.node to check for objects or arrays of objects

static propTypes = {
   children: PropTypes.node.isRequired,
}

It looks like what you want to do is remove your first merge. You could follow the following procedure:

git checkout master      # Let's make sure we are on master branch
git reset --hard master~ # Let's get back to master before the merge
git pull                 # or git merge remote/master
git merge topic

That would give you what you want.

String result = String.format("%4d", i * j);

// Write the result to standard output
System.out.println( result );

I prefer @Ista solution, cause needs no extra package and is simple.
A modification of the data.table solution also solve my problem, and is more general.
My data.frame is

> str(df)
'data.frame':   579 obs. of  11 variables:
 $ trees     : num  2000 5000 1000 2000 1000 1000 2000 5000 5000 1000 ...
 $ interDepth: num  2 3 5 2 3 4 4 2 3 5 ...
 $ minObs    : num  6 4 1 4 10 6 10 10 6 6 ...
 $ shrinkage : num  0.01 0.001 0.01 0.005 0.01 0.01 0.001 0.005 0.005 0.001     ...
 $ G1        : num  0 2 2 2 2 2 8 8 8 8 ...
 $ G2        : logi  FALSE FALSE FALSE FALSE FALSE FALSE ...
 $ qx        : num  0.44 0.43 0.419 0.439 0.43 ...
 $ efet      : num  43.1 40.6 39.9 39.2 38.6 ...
 $ prec      : num  0.606 0.593 0.587 0.582 0.574 0.578 0.576 0.579 0.588 0.585 ...
 $ sens      : num  0.575 0.57 0.573 0.575 0.587 0.574 0.576 0.566 0.542 0.545 ...

The data.table solution needs order on i to do the job:

> require(data.table)
> dt1 <- data.table(df)
> dt2 = dt1[order(-efet, G1, G2), head(.SD, 3), by = .(G1, G2)]
> dt2

By some reason, it does not order the way pointed (probably because ordering by the groups). So, another ordering is done.

A transient variable is a variable that may not be serialized.

One example of when this might be useful that comes to mind is, variables that make only sense in the context of a specific object instance and which become invalid once you have serialized and deserialized the object. In that case it is useful to have those variables become null instead so that you can re-initialize them with useful data when needed.

The find method returns a Cursor instance, which allows you to iterate over all matching documents.

To get the first document that matches the given criteria you need to use find_one. The result of find_one is a dictionary.

You can always use the list constructor to return a list of all the documents in the collection but bear in mind that this will load all the data in memory and may not be what you want.

You should do that if you need to reuse the cursor and have a good reason not to use rewind()

Demo using find:

>>> import pymongo
>>> conn = pymongo.MongoClient()
>>> db = conn.test #test is my database
>>> col = db.spam #Here spam is my collection
>>> cur = col.find()  
>>> cur
<pymongo.cursor.Cursor object at 0xb6d447ec>
>>> for doc in cur:
...     print(doc)  # or do something with the document
... 
{'a': 1, '_id': ObjectId('54ff30faadd8f30feb90268f'), 'b': 2}
{'a': 1, 'c': 3, '_id': ObjectId('54ff32a2add8f30feb902690'), 'b': 2}

Demo using find_one:

>>> col.find_one()
{'a': 1, '_id': ObjectId('54ff30faadd8f30feb90268f'), 'b': 2}

As an example of what del can be used for, I find it useful i situations like this:

def f(a, b, c=3):
    return '{} {} {}'.format(a, b, c)

def g(**kwargs):
    if 'c' in kwargs and kwargs['c'] is None:
        del kwargs['c']

    return f(**kwargs)

# g(a=1, b=2, c=None) === '1 2 3'
# g(a=1, b=2) === '1 2 3'
# g(a=1, b=2, c=4) === '1 2 4'

These two functions can be in different packages/modules and the programmer doesn't need to know what default value argument c in f actually have. So by using kwargs in combination with del you can say "I want the default value on c" by setting it to None (or in this case also leave it).

You could do the same thing with something like:

def g(a, b, c=None):
    kwargs = {'a': a,
              'b': b}
    if c is not None:
        kwargs['c'] = c

    return f(**kwargs)

However I find the previous example more DRY and elegant.

I believe this is an old question, and the Traffic was introduced by Github in 2014. Here is the link to the description of Traffic, that tells you the views on your repositories.

Swift is worry that your case statement is not covering all cases, to fix it you need to create a default case:

do {
    let sandwich = try makeMeSandwich(kitchen)
    print("i eat it \(sandwich)")
} catch SandwichError.NotMe {
    print("Not me error")
} catch SandwichError.DoItYourself {
    print("do it error")
} catch Default {
    print("Another Error")
}

echo '<a href="' . $folder_path . '">Link text</a>';

Please note that you must use the path relative to your domain and, if the folder path is outside the public htdocs directory, it will not work.

EDIT: maybe i misreaded the question; you have a file on your pc and want to insert the path on the html page, and then send it to the server?

The custom format hh:mm only shows the number of hours correctly up to 23:59, after that, you get the remainder, less full days. For example, 48 hours would be displayed as 00:00, even though the underlaying value is correct.

To correctly display duration in hours and seconds (below or beyond a full day), you should use the custom format [h]:mm;@ In this case, 48 hours would be displayed as 48:00.

Cheers.

1. Check that you have execute permission on the script. i.e. chmod +x foo.sh
2. Check that the first line of that script is #!/bin/sh or some such.
3. For sudo you are in the wrong directory. check with sudo pwd

It might be a java interpreter defect, but java on HPUX does not do a kill -9, but only a kill -TERM.

I did a small test testDestroy.java:

ProcessBuilder pb = new ProcessBuilder(args);
Process process = pb.start();
Thread.sleep(1000);
process.destroy();
process.waitFor();

And the invocation:

$ tusc -f -p -s signal,kill -e /opt/java1.5/bin/java testDestroy sh -c 'trap "echo TERM" TERM; sleep 10'

dies after 10s (not killed after 1s as expected) and shows:

...
[19999]   Received signal 15, SIGTERM, in waitpid(), [caught], no siginfo
[19998] kill(19999, SIGTERM) ............................................................................. = 0
...

Doing the same on windows seems to kill the process fine even if signal is handled (but that might be due to windows not using signals to destroy).

Actually i found Java - Process.destroy() source code for Linux related thread and openjava implementation seems to use -TERM as well, which seems very wrong.

I'm using intelliJ 15 community edition and I'm able to right click a file and select 'add to .gitignore'

This will format column A as text, B as General, C as a number.

Sub formatColumns()
 Columns(1).NumberFormat = "@"
 Columns(2).NumberFormat = "General"
 Columns(3).NumberFormat = "0"
End Sub

There are several ways in which you can set the timeout for php-fpm. In /etc/php5/fpm/pool.d/www.conf I added this line:

request_terminate_timeout = 180

Also, in /etc/nginx/sites-available/default I added the following line to the location block of the server in question:

fastcgi_read_timeout 180;

The entire location block looks like this:

location ~ \.php$ {
    fastcgi_pass unix:/var/run/php5-fpm.sock;
    fastcgi_index index.php;
    fastcgi_param   SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_read_timeout 180;
    include fastcgi_params;
} 

Now just restart php-fpm and nginx and there should be no more timeouts for requests taking less than 180 seconds.

There is another approach. In my example you see some business logic in repository class that I use with dependency injection in ASP .NET MVC Core 3.1.

And here I want to get connectiongString for that business logic because probably another repository will have access to another database at all.

This pattern allows you in the same business logic repository have access to different databases.

C#

public interface IStatsRepository
{
            IEnumerable<FederalDistrict> FederalDistricts();
}

class StatsRepository : IStatsRepository
{
   private readonly DbContextOptionsBuilder<EFCoreTestContext>
                optionsBuilder = new DbContextOptionsBuilder<EFCoreTestContext>();
   private readonly IConfigurationRoot configurationRoot;

   public StatsRepository()
   {
       IConfigurationBuilder configurationBuilder = new ConfigurationBuilder().SetBasePath(Environment.CurrentDirectory)
           .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true);
       configurationRoot = configurationBuilder.Build();
   }

   public IEnumerable<FederalDistrict> FederalDistricts()
   {
        var conn = configurationRoot.GetConnectionString("EFCoreTestContext");
        optionsBuilder.UseSqlServer(conn);

        using (var ctx = new EFCoreTestContext(optionsBuilder.Options))
        { 
            return ctx.FederalDistricts.Include(x => x.FederalSubjects).ToList();
        }
    }
}

appsettings.json

You can control the <br> height if you put it inside a height limited div. Try:

<div style="height:2px;"><br></div>

The best way to convert it to HashMap<String, Object> is this:

HashMap<String, Object> result = new ObjectMapper().readValue(jsonString, new TypeReference<Map<String, Object>>(){}));

Try getting hold of a URL for your classpath resource:

URL url = this.getClass().getResource("/com/path/to/file.txt")

Then create a file using the constructor that accepts a URI:

File file = new File(url.toURI());

Worked for me for below version and on iOS

Step to resolve Close the current running Metro Bundler Try Re-run your Metro Bundler and check if this issue persists

Hope this will help !

This worked for me

If build are missing from Itunes 'Activity' tab. Then check your info.plist keys. If all keys are there, then check all keys description. if their length is short then increase your keys description length.

Java

This should work:

// Gets linearlayout
LinearLayout layout = findViewById(R.id.numberPadLayout);
// Gets the layout params that will allow you to resize the layout
LayoutParams params = layout.getLayoutParams();
// Changes the height and width to the specified *pixels*
params.height = 100;
params.width = 100;
layout.setLayoutParams(params);

If you want to convert dip to pixels, use this:

int height = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, <HEIGHT>, getResources().getDisplayMetrics());

Kotlin

std::div returns a structure with both result and remainder.

I created a module to make dealing with trusted hosts slightly easier, psTrustedHosts. You can find the repo here on GitHub. It provides four functions that make working with trusted hosts easy: Add-TrustedHost, Clear-TrustedHost, Get-TrustedHost, and Remove-TrustedHost. You can install the module from PowerShell Gallery with the following command:

Install-Module psTrustedHosts -Force

In your example, if you wanted to append hosts 'machineC' and 'machineD' you would simply use the following command:

Add-TrustedHost 'machineC','machineD'

To be clear, this adds hosts 'machineC' and 'machineD' to any hosts that already exist, it does not overwrite existing hosts.

The Add-TrustedHost command supports pipeline processing as well (so does the Remove-TrustedHost command) so you could also do the following:

'machineC','machineD' | Add-TrustedHost

Actually...

To hide an absolute positioned element, the container position must be anything except for static. It can be relative or fixed in addition to absolute.

You can use Enumeration:

Hashtable<Integer, String> table = ...

Enumeration<Integer> enumKey = table.keys();
while(enumKey.hasMoreElements()) {
    Integer key = enumKey.nextElement();
    String val = table.get(key);
    if(key==0 && val.equals("0"))
        table.remove(key);
}

Can't add a comment to the excellent explanation in the other post but wanted to mention that a great documentation source can be found here.

It is enough to register an event function for accelerometer like so:

if(window.DeviceMotionEvent){
  window.addEventListener("devicemotion", motion, false);
}else{
  console.log("DeviceMotionEvent is not supported");
}

with the handler:

function motion(event){
  console.log("Accelerometer: "
    + event.accelerationIncludingGravity.x + ", "
    + event.accelerationIncludingGravity.y + ", "
    + event.accelerationIncludingGravity.z
  );
}

And for magnetometer a following event handler has to be registered:

if(window.DeviceOrientationEvent){
  window.addEventListener("deviceorientation", orientation, false);
}else{
  console.log("DeviceOrientationEvent is not supported");
}

with a handler:

function orientation(event){
  console.log("Magnetometer: "
    + event.alpha + ", "
    + event.beta + ", "
    + event.gamma
  );
}

There are also fields specified in the motion event for a gyroscope but that does not seem to be universally supported (e.g. it didn't work on a Samsung Galaxy Note).

There is a simple working code on GitHub

try this function:

+It Hides The PlaceHolder On Focus And Returns It Back On Blur

+This function depends on the placeholder selector, first it selects the elements with the placeholder attribute, triggers a function on focusing and another one on blurring.

on focus : it adds an attribute "data-text" to the element which gets its value from the placeholder attribute then it removes the value of the placeholder attribute.

on blur : it returns back the placeholder value and removes it from the data-text attribute

<input type="text" placeholder="Username" />

$('[placeholder]').focus(function() {
    $(this).attr('data-text', $(this).attr('placeholder'));
    $(this).attr('placeholder', '');
  }).blur(function() {
      $(this).attr('placeholder', $(this).attr('data-text'));
      $(this).attr('data-text', '');
  });
});

you can follow me very well if you look what's happening behind the scenes by inspecting the input element

I tried switching from simplejson to builtin json for GAE 2.7, and had issues with the decimal. If default returned str(o) there were quotes (because _iterencode calls _iterencode on the results of default), and float(o) would remove trailing 0.

If default returns an object of a class that inherits from float (or anything that calls repr without additional formatting) and has a custom __repr__ method, it seems to work like I want it to.

import json
from decimal import Decimal

class fakefloat(float):
    def __init__(self, value):
        self._value = value
    def __repr__(self):
        return str(self._value)

def defaultencode(o):
    if isinstance(o, Decimal):
        # Subclass float with custom repr?
        return fakefloat(o)
    raise TypeError(repr(o) + " is not JSON serializable")

json.dumps([10.20, "10.20", Decimal('10.20')], default=defaultencode)
'[10.2, "10.20", 10.20]'

Try:

SELECT convert(datetime, '23/07/2009', 103)

this is British/French standard.

I know its too late but this solution is working perfect for both .net framework and .net core:

@System.Web.HttpUtility.JavaScriptStringEncode()

Do this

<footer style="position: fixed; bottom: 0; width: 100%;"> </footer>

You can also read about flex it is supported by all modern browsers

Update: I read about flex and tried it. It worked for me. Hope it does the same for you. Here is how I implemented.Here main is not the ID it is the div

body {
    margin: 0;
    display: flex;
    min-height: 100vh;
    flex-direction: column;
}

main {
    display: block;
    flex: 1 0 auto;
}

Here you can read more about flex https://css-tricks.com/snippets/css/a-guide-to-flexbox/

Do keep in mind it is not supported by older versions of IE.

In python you would use a dictionary.

It is a very important type in python and often used.

You can create one easily by

name = {}

Dictionaries have many methods:

# add entries:
>>> name['first'] = 'John'
>>> name['second'] = 'Doe'
>>> name
{'first': 'John', 'second': 'Doe'}

# you can store all objects and datatypes as value in a dictionary
# as key you can use all objects and datatypes that are hashable
>>> name['list'] = ['list', 'inside', 'dict']
>>> name[1] = 1
>>> name
{'first': 'John', 'second': 'Doe', 1: 1, 'list': ['list', 'inside', 'dict']}

You can not influence the order of a dict.

one of the easy way to do that is use landa function without any problem like

userControl_Material1.simpleButton4.Click += (s, ee) =>
            {
                Save_mat(mat_global);
            };

My experience of XmlReader is that it's very easy to accidentally read too much. I know you've said you want to read it as quickly as possible, but have you tried using a DOM model instead? I've found that LINQ to XML makes XML work much much easier.

If your document is particularly huge, you can combine XmlReader and LINQ to XML by creating an XElement from an XmlReader for each of your "outer" elements in a streaming manner: this lets you do most of the conversion work in LINQ to XML, but still only need a small portion of the document in memory at any one time. Here's some sample code (adapted slightly from this blog post):

static IEnumerable<XElement> SimpleStreamAxis(string inputUrl,
                                              string elementName)
{
  using (XmlReader reader = XmlReader.Create(inputUrl))
  {
    reader.MoveToContent();
    while (reader.Read())
    {
      if (reader.NodeType == XmlNodeType.Element)
      {
        if (reader.Name == elementName)
        {
          XElement el = XNode.ReadFrom(reader) as XElement;
          if (el != null)
          {
            yield return el;
          }
        }
      }

I've used this to convert the StackOverflow user data (which is enormous) into another format before - it works very well.

EDIT from radarbob, reformatted by Jon - although it's not quite clear which "read too far" problem is being referred to...

This should simplify the nesting and take care of the "a read too far" problem.

using (XmlReader reader = XmlReader.Create(inputUrl))
{
    reader.ReadStartElement("theRootElement");

    while (reader.Name == "TheNodeIWant")
    {
        XElement el = (XElement) XNode.ReadFrom(reader);
    }

    reader.ReadEndElement();
}

This takes care of "a read too far" problem because it implements the classic while loop pattern:

initial read;
(while "we're not at the end") {
    do stuff;
    read;
}

About your command line:

root@debian:/# sudo iptables -A INPUT -p tcp --dport 3306 --jump ACCEPT
root@debian:/# iptables-save

• You are already authenticated as root so sudo is redundant there.

• You are missing the -j or --jump just before the ACCEPT parameter (just tought that was a typo and you are inserting it correctly).

About yout question:

If you are inserting the iptables rule correctly as you pointed it in the question, maybe the issue is related to the hypervisor (virtual machine provider) you are using.

If you provide the hypervisor name (VirtualBox, VMWare?) I can further guide you on this but here are some suggestions you can try first:

check your vmachine network settings and:

• if it is set to NAT, then you won't be able to connect from your base machine to the vmachine.

• if it is set to Hosted, you have to configure first its network settings, it is usually to provide them an IP in the range 192.168.56.0/24, since is the default the hypervisors use for this.

• if it is set to Bridge, same as Hosted but you can configure it whenever IP range makes sense for you configuration.

Hope this helps.

You can use the following command :

$ grep "phpmyadmin" $path_to_access.log | grep -Po "^\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}" | sort | uniq | xargs -I% sudo iptables -A INPUT -s % -j DROP 

Explanation:

Make sure your IP isn't listed before piping through iptables drop!!

This will first find all lines in $path_to_access.log that have phpmyadmin in them,

then grep out the ip address from the start of the line,

then sort and unique them,

then add a rule to drop them in iptables

Again, just edit in echo % at the end instead of the iptables command to make sure your IP isn't in there. Don't inadvertently ban your access to the server!

Limitations

You may need to change the grep part of the command if you're on mac or any system that doesn't have grep -P. I'm not sure if all systems start with xargs, so that might need to be installed too. It's super useful anyway if you do a lot of bash.

here is my solution. I have also extended the PDO class:

class Db extends PDO
{

    /**
     * SELECT ... WHERE fieldName IN (:paramName) workaround
     *
     * @param array  $array
     * @param string $prefix
     *
     * @return string
     */
    public function CreateArrayBindParamNames(array $array, $prefix = 'id_')
    {
        $newparams = [];
        foreach ($array as $n => $val)
        {
            $newparams[] = ":".$prefix.$n;
        }
        return implode(", ", $newparams);
    }

    /**
     * Bind every array element to the proper named parameter
     *
     * @param PDOStatement $stmt
     * @param array        $array
     * @param string       $prefix
     */
    public function BindArrayParam(PDOStatement &$stmt, array $array, $prefix = 'id_')
    {
        foreach($array as $n => $val)
        {
            $val = intval($val);
            $stmt -> bindParam(":".$prefix.$n, $val, PDO::PARAM_INT);
        }
    }
}

Here is a sample usage for the above code:

$idList = [1, 2, 3, 4];
$stmt = $this -> db -> prepare("
  SELECT
    `Name`
  FROM
    `User`
  WHERE
    (`ID` IN (".$this -> db -> CreateArrayBindParamNames($idList)."))");
$this -> db -> BindArrayParam($stmt, $idList);
$stmt -> execute();
foreach($stmt as $row)
{
    echo $row['Name'];
}

Let me know what you think

To add that using Jquery:

$('#commentForm').submit(function(){ //listen for submit event
    $.each(params, function(i,param){
        $('<input />').attr('type', 'hidden')
            .attr('name', param.name)
            .attr('value', param.value)
            .appendTo('#commentForm');
    });

    return true;
}); 

String's search function is useful too. It searches for a character as well as a sub_string in a given string.

'apple'.search('pl') returns 2

'apple'.search('x') return -1

Here is the working code for the same.. its a recursion on each step checking possibility of each combinations on occurrence of same digit in a series....I am not sure if there is any better solution then this from complexity point of view.....

Please let me know for any issues....

Just to expand on @splattne's answer a little:

MapPath(string virtualPath) calls the following:

public string MapPath(string virtualPath)
{
    return this.MapPath(VirtualPath.CreateAllowNull(virtualPath));
}

MapPath(VirtualPath virtualPath) in turn calls MapPath(VirtualPath virtualPath, VirtualPath baseVirtualDir, bool allowCrossAppMapping) which contains the following:

//...
if (virtualPath == null)
{
    virtualPath = VirtualPath.Create(".");
}
//...

So if you call MapPath(null) or MapPath(""), you are effectively calling MapPath(".")

You can create a linked server and reference the table in the other instance using its fully qualified Server.Catalog.Schema.Table name.

If you have not yet garbage collected your repository (e.g. using git repack -d or git gc, but note that garbage collection can also happen automatically), then your commit is still there – it's just no longer reachable through the HEAD.

You can try to find your commit by looking through the output of git fsck --lost-found.

Newer versions of Git have something called the "reflog", which is a log of all changes that are made to the refs (as opposed to changes that are made to the repository contents). So, for example, every time you switch your HEAD (i.e. every time you do a git checkout to switch branches) that will be logged. And, of course, your git reset also manipulated the HEAD, so it was also logged. You can access older states of your refs in a similar way that you can access older states of your repository, by using an @ sign instead of a ~, like git reset HEAD@{1}.

It took me a while to understand what the difference is between HEAD@{1} and HEAD~1, so here is a little explanation:

git init
git commit --allow-empty -mOne
git commit --allow-empty -mTwo
git checkout -b anotherbranch
git commit --allow-empty -mThree
git checkout master # This changes the HEAD, but not the repository contents
git show HEAD~1 # => One
git show HEAD@{1} # => Three
git reflog

So, HEAD~1 means "go to the commit before the commit that HEAD currently points at", while HEAD@{1} means "go to the commit that HEAD pointed at before it pointed at where it currently points at".

That will easily allow you to find your lost commit and recover it.

A "floating point number" is how computers usually represent numbers that are not integers -- basically, a number with a decimal point. In C++ you declare them with float instead of int. A floating point exception is an error that occurs when you try to do something impossible with a floating point number, such as divide by zero.

open the gradlew file with android studio, everything will be downloaded

Not enough points to comment on an existing answer, but similar to some people above, I wound up just adding a macro & keymap to Organize Imports / Format / SaveAll / FastReload(F9) / Synchronize.

The synchronize is added as it seems to be the only way I can also see updates in resources modified by external build tools / watchers (i.e., webpack).

The process is slower than eclipse - and for the external file refresh often have to run the command multiple times - but suppose I can live with it.

I suggest using a directive on a link.

But its not perfect yet. Watch out for the hashbangs ;)

Here is the javascript for directive:

angular.module('link', []).
  directive('activeLink', ['$location', function (location) {
    return {
      restrict: 'A',
      link: function(scope, element, attrs, controller) {
        var clazz = attrs.activeLink;
        var path = attrs.href;
        path = path.substring(1); //hack because path does not return including hashbang
        scope.location = location;
        scope.$watch('location.path()', function (newPath) {
          if (path === newPath) {
            element.addClass(clazz);
          } else {
            element.removeClass(clazz);
          }
        });
      }
    };
  }]);

and here is how it would be used in html:

<div ng-app="link">
  <a href="#/one" active-link="active">One</a>
  <a href="#/two" active-link="active">One</a>
  <a href="#" active-link="active">home</a>
</div>

afterwards styling with css:

.active { color: red; }

In my experience, don't use ffmpeg for splitting/join. MP4Box, is faster and light than ffmpeg. Please tryit. Eg if you want to split a 1400mb MP4 file into two parts a 700mb you can use the following cmdl: MP4Box -splits 716800 input.mp4 eg for concatenating two files you can use:

MP4Box -cat file1.mp4 -cat file2.mp4 output.mp4

Or if you need split by time, use -splitx StartTime:EndTime:

MP4Box -add input.mp4 -splitx 0:15 -new split.mp4

• db:migrate runs (single) migrations that have not run yet.

• db:create creates the database

• db:drop deletes the database

• db:schema:load creates tables and columns within the existing database following schema.rb. This will delete existing data.

• db:setup does db:create, db:schema:load, db:seed

• db:reset does db:drop, db:setup

• db:migrate:reset does db:drop, db:create, db:migrate

Typically, you would use db:migrate after having made changes to the schema via new migration files (this makes sense only if there is already data in the database). db:schema:load is used when you setup a new instance of your app.

I hope that helps.

UPDATE for rails 3.2.12:

I just checked the source and the dependencies are like this now:

• db:create creates the database for the current env

• db:create:all creates the databases for all envs

• db:drop drops the database for the current env

• db:drop:all drops the databases for all envs

• db:migrate runs migrations for the current env that have not run yet

• db:migrate:up runs one specific migration

• db:migrate:down rolls back one specific migration

• db:migrate:status shows current migration status

• db:rollback rolls back the last migration

• db:forward advances the current schema version to the next one

• db:seed (only) runs the db/seed.rb file

• db:schema:load loads the schema into the current env's database

• db:schema:dump dumps the current env's schema (and seems to create the db as well)

• db:setup runs db:schema:load, db:seed

• db:reset runs db:drop db:setup

• db:migrate:redo runs (db:migrate:down db:migrate:up) or (db:rollback db:migrate) depending on the specified migration

• db:migrate:reset runs db:drop db:create db:migrate

I'm not sure that there is any option for simply printing the full effective search path.

But: the search path consists of directories specified by -L options on the command line, followed by directories added to the search path by SEARCH_DIR("...") directives in the linker script(s). So you can work it out if you can see both of those, which you can do as follows:

If you're invoking ld directly:

• The -L options are whatever you've said they are.
• To see the linker script, add the --verbose option. Look for the SEARCH_DIR("...") directives, usually near the top of the output. (Note that these are not necessarily the same for every invocation of ld -- the linker has a number of different built-in default linker scripts, and chooses between them based on various other linker options.)

If you're linking via gcc:

• You can pass the -v option to gcc so that it shows you how it invokes the linker. In fact, it normally does not invoke ld directly, but indirectly via a tool called collect2 (which lives in one of its internal directories), which in turn invokes ld. That will show you what -L options are being used.
• You can add -Wl,--verbose to the gcc options to make it pass --verbose through to the linker, to see the linker script as described above.

If you're accessing this via a View then try sp_recompile or refreshing views.

sp_recompile:

Causes stored procedures, triggers, and user-defined functions to be recompiled the next time that they are run. It does this by dropping the existing plan from the procedure cache forcing a new plan to be created the next time that the procedure or trigger is run. In a SQL Server Profiler collection, the event SP:CacheInsert is logged instead of the event SP:Recompile.

Arguments

[ @objname= ] 'object'

The qualified or unqualified name of a stored procedure, trigger, table, view, or user-defined function in the current database. object is nvarchar(776), with no default. If object is the name of a stored procedure, trigger, or user-defined function, the stored procedure, trigger, or function will be recompiled the next time that it is run. If object is the name of a table or view, all the stored procedures, triggers, or user-defined functions that reference the table or view will be recompiled the next time that they are run.

Return Code Values

0 (success) or a nonzero number (failure)

Remarks

sp_recompile looks for an object in the current database only.

The queries used by stored procedures, or triggers, and user-defined functions are optimized only when they are compiled. As indexes or other changes that affect statistics are made to the database, compiled stored procedures, triggers, and user-defined functions may lose efficiency. By recompiling stored procedures and triggers that act on a table, you can reoptimize the queries.

For .NET DLLs you can use ildasm

The correct answer is following:

#define BitsCount( val ) ( sizeof( val ) * CHAR_BIT )
#define Shift( val, steps ) ( steps % BitsCount( val ) )
#define ROL( val, steps ) ( ( val << Shift( val, steps ) ) | ( val >> ( BitsCount( val ) - Shift( val, steps ) ) ) )
#define ROR( val, steps ) ( ( val >> Shift( val, steps ) ) | ( val << ( BitsCount( val ) - Shift( val, steps ) ) ) )

This problem happened to me because I had the hibernate.default_schema set to a different database than the one in the DataSource.

Being strict on my mysql user permissions, when hibernate tried to query a table it queried the one in the hibernate.default_schema database for which the user had no permissions.

Its unfortunate that mysql does not correctly specify the database in this error message, as that would've cleared things up straight away.

I ran into the same problem and after a couple of hours of logging and investigating, I fixed it.

It turned out that for the first time the value is set in a date picker, $viewValue is a string so the dateFilter displays it as is. All I did is parse it into a Date object.

Search for that block in ui-bootstrap-tpls file

  ngModel.$render = function() {
    var date = ngModel.$viewValue ? dateFilter(ngModel.$viewValue, dateFormat) : '';
    element.val(date);

    updateCalendar();
  };

and replace it by:

  ngModel.$render = function() {
    ngModel.$viewValue = new Date(ngModel.$viewValue);
    var date = ngModel.$viewValue ? dateFilter(ngModel.$viewValue, dateFormat) : '';
    element.val(date);

    updateCalendar();
  };

Hopefully this will help :)

<location path="ControllerName/ActionName">
    <system.web>
        <httpRuntime executionTimeout="1000"/>
    </system.web>
</location>

Probably it is better to set such values in web.config instead of controller. Hardcoding of configurable options is considered harmful.

You can use substring from String.class (handling exceptions) or from Apache lang commons (it handles exceptions for you)

static String   substring(String str, int start, int end) 

Put it inside a loop and you are good to go.

Actually, you only need to use the default argument to add_argument as in this test.py script:

import argparse

if __name__ == '__main__':

    parser = argparse.ArgumentParser()
    parser.add_argument('--example', default=1)
    args = parser.parse_args()
    print(args.example)

test.py --example
% 1
test.py --example 2
% 2

I have always tested the number of open workbooks in Workbook_Open(). If it is 1, then the workbook was opened by the command line (or the user closed all the workbooks, then opened this one).

If Workbooks.Count = 1 Then

    ' execute the macro or call another procedure - I always do the latter  
    PublishReport

    ThisWorkbook.Save

    Application.Quit

End If

Building on the answer by @unutbu, I have compared the iteration performance of two identical lists when using Python 3.6's zip() functions, Python's enumerate() function, using a manual counter (see count() function), using an index-list, and during a special scenario where the elements of one of the two lists (either foo or bar) may be used to index the other list. Their performances for printing and creating a new list, respectively, were investigated using the timeit() function where the number of repetitions used was 1000 times. One of the Python scripts that I had created to perform these investigations is given below. The sizes of the foo and bar lists had ranged from 10 to 1,000,000 elements.

Results:

1. For printing purposes: The performances of all the considered approaches were observed to be approximately similar to the zip() function, after factoring an accuracy tolerance of +/-5%. An exception occurred when the list size was smaller than 100 elements. In such a scenario, the index-list method was slightly slower than the zip() function while the enumerate() function was ~9% faster. The other methods yielded similar performance to the zip() function.

   

2. For creating lists: Two types of list creation approaches were explored: using the (a) list.append() method and (b) list comprehension. After factoring an accuracy tolerance of +/-5%, for both of these approaches, the zip() function was found to perform faster than the enumerate() function, than using a list-index, than using a manual counter. The performance gain by the zip() function in these comparisons can be 5% to 60% faster. Interestingly, using the element of foo to index bar can yield equivalent or faster performances (5% to 20%) than the zip() function.

   

Making sense of these results:

A programmer has to determine the amount of compute-time per operation that is meaningful or that is of significance.

For example, for printing purposes, if this time criterion is 1 second, i.e. 10**0 sec, then looking at the y-axis of the graph that is on the left at 1 sec and projecting it horizontally until it reaches the monomials curves, we see that lists sizes that are more than 144 elements will incur significant compute cost and significance to the programmer. That is, any performance gained by the approaches mentioned in this investigation for smaller list sizes will be insignificant to the programmer. The programmer will conclude that the performance of the zip() function to iterate print statements is similar to the other approaches.

Conclusion

Notable performance can be gained from using the zip() function to iterate through two lists in parallel during list creation. When iterating through two lists in parallel to print out the elements of the two lists, the zip() function will yield similar performance as the enumerate() function, as to using a manual counter variable, as to using an index-list, and as to during the special scenario where the elements of one of the two lists (either foo or bar) may be used to index the other list.

The Python3.6 Script that was used to investigate list creation.

import timeit
import matplotlib.pyplot as plt
import numpy as np

    store = []

I was getting this error with Laravel Sanctum. I fixed it by adding \Illuminate\Session\Middleware\StartSession::class, to the api middleware group in Kernel.php, but I later figured out this "worked" because my authentication routes were added in api.php instead of web.php, so Laravel was using the wrong auth guard.

I moved these routes here into web.php and then they started working properly with the AuthenticatesUsers.php trait:

Route::group(['middleware' => ['guest', 'throttle:10,5']], function () {
    Route::post('register', 'Auth\RegisterController@register')->name('register');
    Route::post('login', 'Auth\LoginController@login')->name('login');

    Route::post('password/email', 'Auth\ForgotPasswordController@sendResetLinkEmail');
    Route::post('password/reset', 'Auth\ResetPasswordController@reset');

    Route::post('email/verify/{user}', 'Auth\VerificationController@verify')->name('verification.verify');
    Route::post('email/resend', 'Auth\VerificationController@resend');

    Route::post('oauth/{driver}', 'Auth\OAuthController@redirectToProvider')->name('oauth.redirect');
    Route::get('oauth/{driver}/callback', 'Auth\OAuthController@handleProviderCallback')->name('oauth.callback');
});

Route::post('logout', 'Auth\LoginController@logout')->name('logout');

I figured out the problem after I got another weird error about RequestGuard::logout() does not exist.

It made me realize that my custom auth routes are calling methods from the AuthenticatesUsers trait, but I wasn't using Auth::routes() to accomplish it. Then I realized Laravel uses the web guard by default and that means routes should be in routes/web.php.

This is what my settings look like now with Sanctum and a decoupled Vue SPA app:

Kernel.php

protected $middlewareGroups = [
    'web' => [
        \App\Http\Middleware\EncryptCookies::class,
        \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
        \Illuminate\Session\Middleware\StartSession::class,
        // \Illuminate\Session\Middleware\AuthenticateSession::class,
        \Illuminate\View\Middleware\ShareErrorsFromSession::class,
        \App\Http\Middleware\VerifyCsrfToken::class,
        \Illuminate\Routing\Middleware\SubstituteBindings::class,
    ],

    'api' => [
        EnsureFrontendRequestsAreStateful::class,
        \Illuminate\Routing\Middleware\SubstituteBindings::class,
        'throttle:60,1',
    ],
];

Note: With Laravel Sanctum and same-domain Vue SPA, you use httpOnly cookies for session cookie, and remember me cookie, and unsecure cookie for CSRF, so you use the web guard for auth, and every other protected, JSON-returning route should use auth:sanctum middleware.

config/auth.php

'defaults' => [
    'guard' => 'web',
    'passwords' => 'users',
],

...

'guards' => [
    'web' => [
        'driver' => 'session',
        'provider' => 'users',
    ],

    'api' => [
        'driver' => 'token',
        'provider' => 'users',
        'hash' => false,
    ],
],

Then you can have unit tests such as this, where critically, Auth::check(), Auth::user(), and Auth::logout() work as expected with minimal config and maximal usage of AuthenticatesUsers and RegistersUsers traits.

Here are a couple of my login unit tests:

TestCase.php

/**
 * Creates and/or returns the designated regular user for unit testing
 *
 * @return \App\User
 */
public function user() : User
{
    $user = User::query()->firstWhere('email', '[email protected]');

    if ($user) {
        return $user;
    }

    // User::generate() is just a wrapper around User::create()
    $user = User::generate('Test User', '[email protected]', self::AUTH_PASSWORD);

    return $user;
}

/**
 * Resets AuthManager state by logging out the user from all auth guards.
 * This is used between unit tests to wipe cached auth state.
 *
 * @param array $guards
 * @return void
 */
protected function resetAuth(array $guards = null) : void
{
    $guards = $guards ?: array_keys(config('auth.guards'));

    foreach ($guards as $guard) {
        $guard = $this->app['auth']->guard($guard);

        if ($guard instanceof SessionGuard) {
            $guard->logout();
        }
    }

    $protectedProperty = new \ReflectionProperty($this->app['auth'], 'guards');
    $protectedProperty->setAccessible(true);
    $protectedProperty->setValue($this->app['auth'], []);
}

LoginTest.php

protected $auth_guard = 'web';

/** @test */
public function it_can_login()
{
    $user = $this->user();

    $this->postJson(route('login'), ['email' => $user->email, 'password' => TestCase::AUTH_PASSWORD])
        ->assertStatus(200)
        ->assertJsonStructure([
            'user' => [
                ...expectedUserFields,
            ],
        ]);

    $this->assertEquals(Auth::check(), true);
    $this->assertEquals(Auth::user()->email, $user->email);
    $this->assertAuthenticated($this->auth_guard);
    $this->assertAuthenticatedAs($user, $this->auth_guard);

    $this->resetAuth();
}

/** @test */
public function it_can_logout()
{
    $this->actingAs($this->user())
        ->postJson(route('logout'))
        ->assertStatus(204);

    $this->assertGuest($this->auth_guard);

    $this->resetAuth();
}

I overrided the registered and authenticated methods in the Laravel auth traits so that they return the user object instead of just the 204 OPTIONS:

public function authenticated(Request $request, User $user)
{
    return response()->json([
        'user' => $user,
    ]);
}

protected function registered(Request $request, User $user)
{
    return response()->json([
        'user' => $user,
    ]);
}

Look at the vendor code for the auth traits. You can use them untouched, plus those two above methods.

• vendor/laravel/ui/auth-backend/RegistersUsers.php
• vendor/laravel/ui/auth-backend/AuthenticatesUsers.php

Here is my Vue SPA's Vuex actions for login:

async login({ commit }, credentials) {
    try {
        const { data } = await axios.post(route('login'), {
            ...credentials,
            remember: credentials.remember || undefined,
        });

        commit(FETCH_USER_SUCCESS, { user: data.user });
        commit(LOGIN);

        return commit(CLEAR_INTENDED_URL);
    } catch (err) {
        commit(LOGOUT);
        throw new Error(`auth/login# Problem logging user in: ${err}.`);
    }
},

async logout({ commit }) {
    try {
        await axios.post(route('logout'));

        return commit(LOGOUT);
    } catch (err) {
        commit(LOGOUT);

        throw new Error(`auth/logout# Problem logging user out: ${err}.`);
    }
},

It took me over a week to get Laravel Sanctum + same-domain Vue SPA + auth unit tests all working up to my standard, so hopefully my answer here can help save others time in the future.

You need to use parentheses: myList.insert([1, 2, 3]). When you leave out the parentheses, python thinks you are trying to access myList.insert at position 1, 2, 3, because that's what brackets are used for when they are right next to a variable.

If we are directly use data from csv it will give combine data based on comma separation value as it is .csv file.

user1 = pd.read_csv('dataset/1.csv')

If you want to add column names using pandas, you have to do something like this. But below code will not show separate header for your columns.

col_names=['TIME', 'X', 'Y', 'Z'] 
user1 = pd.read_csv('dataset/1.csv', names=col_names)

To solve above problem we have to add extra filled which is supported by pandas, It is header=None

user1 = pd.read_csv('dataset/1.csv', names=col_names, header=None)

I know this is a little late answer,

you can use if and else statements in ejs as follows

<% if (something) { %>
   // Then do some operation
<% } else { %>
   // Then do some operation
<% } %>

But there is another thing I want to emphasize is that if you use the code this way,

<% if (something) { %>
   // Then do some operation
<% } %>
<% else { %>
   // Then do some operation
<% } %>

It will produce an error.

Hope this will help to someone

Do like this...

import java.util.ArrayList;
import java.util.Arrays;

public class rohit {

    public static void main(String[] args) {
        ArrayList<Integer> a=new ArrayList<Integer>();
        ArrayList<Integer> b=new ArrayList<Integer>();
        b.add(1);
        b.add(2);
        b.add(3);
        permu(a,b);
    }

    public static void permu(ArrayList<Integer> prefix,ArrayList<Integer> value) {
        if(value.size()==0) {
            System.out.println(prefix);
        } else {
            for(int i=0;i<value.size();i++) {
                ArrayList<Integer> a=new ArrayList<Integer>();
                a.addAll(prefix);
                a.add(value.get(i));

                ArrayList<Integer> b=new ArrayList<Integer>();

                b.addAll(value.subList(0, i));
                b.addAll(value.subList(i+1, value.size()));

                permu(a,b);
            }
        }
    }

}

Just try this:

Bitmap bitmap = BitmapFactory.decodeFile("/path/images/image.jpg");
ByteArrayOutputStream blob = new ByteArrayOutputStream();
bitmap.compress(CompressFormat.PNG, 0 /* Ignored for PNGs */, blob);
byte[] bitmapdata = blob.toByteArray();

If bitmapdata is the byte array then getting Bitmap is done like this:

Bitmap bitmap = BitmapFactory.decodeByteArray(bitmapdata, 0, bitmapdata.length);

Returns the decoded Bitmap, or null if the image could not be decoded.

Just to highlight @Darkonaut answer because I think it should be more visible.

new_list = [] or new_list = list() are both fine (ignoring performance), but append() returns None, as result you can't do new_list = new_list.append(something).

Very simple way to do this---

In your Activity--

 TextView tv = (TextView) findViewById(R.id.site);
 tv.setText(Html.fromHtml("<a href=http://www.stackoverflow.com> STACK OVERFLOW "));
 tv.setMovementMethod(LinkMovementMethod.getInstance());

Then you will get just the Tag, not the whole link..

Hope it will help you...

Perhaps it has no special meaning and only needs to be rendered in italics to separate it presentationally from the text preceding it.

If it has no special meaning, why does it need to be separated presentationally from the text preceding it? This run of text looks a bit weird, because I’ve italicised it for no reason.

I do take your point though. It’s not uncommon for designers to produce designs that vary visually, without varying meaningfully. I’ve seen this most often with boxes: designers will give us designs including boxes with various combinations of colours, corners, gradients and drop-shadows, with no relation between the styles, and the meaning of the content.

Because these are reasonably complex styles (with associated Internet Explorer issues) re-used in different places, we create classes like box-1, box-2, so that we can re-use the styles.

The specific example of making some text italic is too trivial to worry about though. Best leave minutiae like that for the Semantic Nutters to argue about.

The ErrorDocument directive, when supplied a local URL path, expects the path to be fully qualified from the DocumentRoot. In your case, this means that the actual path to the ErrorDocument is

ErrorDocument 404 /hellothere/error/404page.html

Compound checking:

   if (thing.foo && thing.foo.bar) {
      ... thing.foor.bar exists;
   }

I have used wire shark tool for monitoring service calls from silver light app in browser to service. try the link gives clear info

It enables you to monitor the whole request and response contents.

Solution to allow Apache 2 to host websites outside of htdocs:

Underneath the "DocumentRoot" directive in httpd.conf, you should see a directory block. Replace this directory block with:

<Directory />
    Options FollowSymLinks
    AllowOverride All
    Allow from all
</Directory> 

REMEMBER NOT TO USE THIS CONFIGURATION IN A REAL ENVIRONMENT

If you don't want to import calendar and apply .isleap method you can try this:

def isleapyear(year):
    if year % 4 == 0 and (year % 100 != 0 or year % 400 == 0):
        return True
    return False

As of August 2020, Google Play's In-App Review API is available and its straightforward implementation is correct as per this answer.

But if you wish add some display logic on top of it, use the Five-Star-Me library.

Set launch times and install days in the onCreate method of the MainActivity to configure the library.

  FiveStarMe.with(this)
      .setInstallDays(0) // default 10, 0 means install day.
      .setLaunchTimes(3) // default 10
      .setDebug(false) // default false
      .monitor();

Then place the below method call on any activity / fragment's onCreate / onViewCreated method to show the prompt whenever the conditions are met.

FiveStarMe.showRateDialogIfMeetsConditions(this); //Where *this* is the current activity.

Installation instructions:

You can download from jitpack.

Step 1: Add this to project (root) build.gradle.

allprojects {
  repositories {
    ...
    maven { url 'https://jitpack.io' }
  }
}

Step 2: Add the following dependency to your module (app) level build.gradle.

dependencies {
  implementation 'com.github.numerative:Five-Star-Me:2.0.0'
}

Sub TEST()
Dim value1 As String
Dim value2 As String
value1 = ThisWorkbook.Sheets(1).Range("A1").Value 'value from sheet1
value2 = ThisWorkbook.Sheets(2).Range("A1").Value 'value from sheet2
If value1 = value2 Then ThisWorkbook.Sheets(2).Range("L1").Value = value1 'or 2
End Sub

This will compare two sheets cells values and if they match place the value on sheet 2 in column L.

You should be able to use join, which joins on the index as default. Given your desired result, you must use outer as the join type.

>>> df1.join(df2, how='outer')
            V1  V2
A 1/1/2012  12  15
  2/1/2012  14 NaN
  3/1/2012 NaN  21
B 1/1/2012  15  24
  2/1/2012   8   9
C 1/1/2012  17 NaN
  2/1/2012   9 NaN
D 1/1/2012 NaN   7
  2/1/2012 NaN  16

Signature: _.join(other, on=None, how='left', lsuffix='', rsuffix='', sort=False) Docstring: Join columns with other DataFrame either on index or on a key column. Efficiently Join multiple DataFrame objects by index at once by passing a list.

To give Network Service read permission on the EventLog/Security key (as suggested by Firenzi and royrules22) follow instructions from http://geekswithblogs.net/timh/archive/2005/10/05/56029.aspx

1. Open the Registry Editor:
   1. Select Start then Run
   2. Enter regedt32 or regedit

2. Navigate/expand to the following key:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Security

3. Right click on this entry and select Permissions

4. Add the Network Service user

5. Give it Read permission

UPDATE: The steps above are ok on developer machines, where you do not use deployment process to install application.
However if you deploy your application to other machine(s), consider to register event log sources during installation as suggested in SailAvid's and Nicole Calinoiu's answers.

I am using PowerShell function (calling in Octopus Deploy.ps1)

function Create-EventSources() {
    $eventSources = @("MySource1","MySource2" )
    foreach ($source in $eventSources) {
            if ([System.Diagnostics.EventLog]::SourceExists($source) -eq $false) {
                [System.Diagnostics.EventLog]::CreateEventSource($source, "Application")
            }
    }
}

My code is as follows:

new java.util.Timer().schedule(

    new java.util.TimerTask() {
        @Override
        public void run() {
            // your code here, and if you have to refresh UI put this code: 
           runOnUiThread(new   Runnable() {
                  public void run() {
                            //your code

                        }
                   });
        }
    }, 
    5000 
);

You can do this:

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

Notice that another issue that might be causing this is that, the "FollowSymLinks" option of a parent directory might have been mistakenly overwritten by the options of your project's directory. This was the case for me and made me pull my hair until I found out the cause!

Here's an example of such a mistake:

<Directory />
        Options FollowSymLinks
        AllowOverride all
        Require all denied
</Directory>

<Directory /var/www/>
        Options Indexes # <--- NOT OK! It's overwriting the above option of the "/" directory.
        AllowOverride all
        Require all granted
</Directory>

So now if you check the Apache's log message(tail -n 50 -f /var/www/html/{the_error_log_file_of_your_site}) you'll see such an error:

Options FollowSymLinks and SymLinksIfOwnerMatch are both off, so the RewriteRule directive
is also forbidden due to its similar ability to circumvent directory restrictions

That's because Indexes in the above rules for /var/www directory is overwriting the FolowSymLinks of the / directory. So now that you know the cause, in order to fix it, you can do many things depending on your need. For instance:

<Directory />
        Options FollowSymLinks
        AllowOverride all
        Require all denied
</Directory>

<Directory /var/www/>
        Options FollowSymLinks Indexes # <--- OK.
        AllowOverride all
        Require all granted
</Directory>

Or even this:

<Directory />
        Options FollowSymLinks
        AllowOverride all
        Require all denied
</Directory>

<Directory /var/www/>
        Options -Indexes # <--- OK as well! It will NOT cause an overwrite.
        AllowOverride all
        Require all granted
</Directory>

The example above will not cause the overwrite issue, because in Apache, if an option is "+" it will overwrite the "+"s only, and if it's a "-", it will overwrite the "-"s... (Don't ask me for a reference on that though, it's just my interpretation of an Apache's error message(checked through journalctl -xe) which says: Either all Options must start with + or -, or no Option may. when an option has a sign, but another one doesn't(E.g., FollowSymLinks -Indexes). So it's my personal conclusion -thus should be taken with a grain of salt- that if I've used -Indexes as the option, that will be considered as a whole distinct set of options by the Apache from the other option in the "/" which doesn't have any signs on it, and so no annoying rewrites will occur in the end, which I could successfully confirm by the above rules in a project directory of my own).

Hope that this will help you pull much less of your hair! :)

I had this problem on Webdriver 3.8.0 (Chrome 73.0.3683.103 and ChromeDriver 73.0.3683.68). The problem disappeared after I did

pip install -U selenium

to upgrade Webdriver to 3.14.1.

I'd like to add a "pure pathlib" approach:

from pathlib import Path
from typing import Union

def del_dir(target: Union[Path, str], only_if_empty: bool = False):
    """
    Delete a given directory and its subdirectories.

    :param target: The directory to delete
    :param only_if_empty: Raise RuntimeError if any file is found in the tree
    """
    target = Path(target).expanduser()
    assert target.is_dir()
    for p in sorted(target.glob('**/*'), reverse=True):
        if not p.exists():
            continue
        p.chmod(0o666)
        if p.is_dir():
            p.rmdir()
        else:
            if only_if_empty:
                raise RuntimeError(f'{p.parent} is not empty!')
            p.unlink()
    target.rmdir()

This relies on the fact that Path is orderable, and longer paths will always sort after shorter paths, just like str. Therefore, directories will come before files. If we reverse the sort, files will then come before their respective containers, so we can simply unlink/rmdir them one by one with one pass.

Benefits:

• It's NOT relying on external binaries: everything uses Python's batteries-included modules (Python >= 3.6)
  • Which means that it does not need to repeatedly start a new subprocess to do unlinking
• It's quite fast & simple; you don't have to implement your own recursion
• It's cross-platform (at least, that's what pathlib promises in Python 3.6; no operation above stated to not run on Windows)
• If needed, one can do a very granular logging, e.g., log each deletion as it happens.

I'm using the following in VC++ and it works like a charm for me.

CA2CT(charText)

You can use "

Similarly, with dictionaries of arrays one can:

var dict1 = [String:[Int]]()
var dict2 = [String:[Int]]()
dict1["key"] = [1,2,3]
dict2["key"] = [4,5,6]
dict1["key"] = dict1["key"]! + dict2["key"]!
print(dict1["key"]!)

and you can iterate over dict1 and add dict2 if the "key" matches

Using pandas it is very simple to read a csv file directly from a url

import pandas as pd
data = pd.read_csv('https://example.com/passkey=wedsmdjsjmdd')

This will read your data in tabular format, which will be very easy to process

scope - https://www.googleapis.com/auth/userinfo.profile

return youraccess_token = access_token

get https://www.googleapis.com/oauth2/v1/userinfo?alt=json&access_token=youraccess_token

you will get json:

{
 "id": "xx",
 "name": "xx",
 "given_name": "xx",
 "family_name": "xx",
 "link": "xx",
 "picture": "xx",
 "gender": "xx",
 "locale": "xx"
}

To Tahir Yasin:

This is a php example.
You can use json_decode function to get userInfo array.

$q = 'https://www.googleapis.com/oauth2/v1/userinfo?access_token=xxx';
$json = file_get_contents($q);
$userInfoArray = json_decode($json,true);
$googleEmail = $userInfoArray['email'];
$googleFirstName = $userInfoArray['given_name'];
$googleLastName = $userInfoArray['family_name'];

I have similar problem and similar resolution:

1) Size

in the xml you have TabLayout,

        <android.support.design.widget.TabLayout
            ...
            app:tabTextAppearance="@style/CustomTextStyle"
            ...
        />

then in style,

        <style name="CustomTextStyle" parent="@android:style/TextAppearance.Widget.TabWidget">
           <item name="android:textSize">16sp</item>
           <item name="android:textAllCaps">true</item>
        </style>

If you do not want the characters in uppercase put false in "android:textAllCaps"

2) Text color of selected or unselected Tabs,

TabLayout tabLayout = (TabLayout) view.findViewById(R.id.tabs);
    tabLayout.setupWithViewPager(viewPager);

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        tabLayout.setTabTextColors(getResources().getColorStateList(R.color.tab_selector,null));
    } else {
        tabLayout.setTabTextColors(getResources().getColorStateList(R.color.tab_selector));
    }

then in res/color/tab_selector.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="@color/white" android:state_selected="true" />
<item android:color="@color/white" />

If you want to clear the div and remove all child nodes, you could put:

var mydiv = document.getElementById('FirstDiv');
while(mydiv.firstChild) {
  mydiv.removeChild(mydiv.firstChild);
}

<p:commandXxx process> <p:ajax process> <f:ajax execute>

The process attribute is server side and can only affect UIComponents implementing EditableValueHolder (input fields) or ActionSource (command fields). The process attribute tells JSF, using a space-separated list of client IDs, which components exactly must be processed through the entire JSF lifecycle upon (partial) form submit.

JSF will then apply the request values (finding HTTP request parameter based on component's own client ID and then either setting it as submitted value in case of EditableValueHolder components or queueing a new ActionEvent in case of ActionSource components), perform conversion, validation and updating the model values (EditableValueHolder components only) and finally invoke the queued ActionEvent (ActionSource components only). JSF will skip processing of all other components which are not covered by process attribute. Also, components whose rendered attribute evaluates to false during apply request values phase will also be skipped as part of safeguard against tampered requests.

Note that it's in case of ActionSource components (such as <p:commandButton>) very important that you also include the component itself in the process attribute, particularly if you intend to invoke the action associated with the component. So the below example which intends to process only certain input component(s) when a certain command component is invoked ain't gonna work:

<p:inputText id="foo" value="#{bean.foo}" />
<p:commandButton process="foo" action="#{bean.action}" />

It would only process the #{bean.foo} and not the #{bean.action}. You'd need to include the command component itself as well:

<p:inputText id="foo" value="#{bean.foo}" />
<p:commandButton process="@this foo" action="#{bean.action}" />

Or, as you apparently found out, using @parent if they happen to be the only components having a common parent:

<p:panel><!-- Type doesn't matter, as long as it's a common parent. -->
    <p:inputText id="foo" value="#{bean.foo}" />
    <p:commandButton process="@parent" action="#{bean.action}" />
</p:panel>

Or, if they both happen to be the only components of the parent UIForm component, then you can also use @form:

<h:form>
    <p:inputText id="foo" value="#{bean.foo}" />
    <p:commandButton process="@form" action="#{bean.action}" />
</h:form>

This is sometimes undesirable if the form contains more input components which you'd like to skip in processing, more than often in cases when you'd like to update another input component(s) or some UI section based on the current input component in an ajax listener method. You namely don't want that validation errors on other input components are preventing the ajax listener method from being executed.

Then there's the @all. This has no special effect in process attribute, but only in update attribute. A process="@all" behaves exactly the same as process="@form". HTML doesn't support submitting multiple forms at once anyway.

There's by the way also a @none which may be useful in case you absolutely don't need to process anything, but only want to update some specific parts via update, particularly those sections whose content doesn't depend on submitted values or action listeners.

Noted should be that the process attribute has no influence on the HTTP request payload (the amount of request parameters). Meaning, the default HTML behavior of sending "everything" contained within the HTML representation of the <h:form> will be not be affected. In case you have a large form, and want to reduce the HTTP request payload to only these absolutely necessary in processing, i.e. only these covered by process attribute, then you can set the partialSubmit attribute in PrimeFaces Ajax components as in <p:commandXxx ... partialSubmit="true"> or <p:ajax ... partialSubmit="true">. You can also configure this 'globally' by editing web.xml and add

<context-param>
    <param-name>primefaces.SUBMIT</param-name>
    <param-value>partial</param-value>
</context-param>

Alternatively, you can also use <o:form> of OmniFaces 3.0+ which defaults to this behavior.

The standard JSF equivalent to the PrimeFaces specific process is execute from <f:ajax execute>. It behaves exactly the same except that it doesn't support a comma-separated string while the PrimeFaces one does (although I personally recommend to just stick to space-separated convention), nor the @parent keyword. Also, it may be useful to know that <p:commandXxx process> defaults to @form while <p:ajax process> and <f:ajax execute> defaults to @this. Finally, it's also useful to know that process supports the so-called "PrimeFaces Selectors", see also How do PrimeFaces Selectors as in update="@(.myClass)" work?

<p:commandXxx update> <p:ajax update> <f:ajax render>

The update attribute is client side and can affect the HTML representation of all UIComponents. The update attribute tells JavaScript (the one responsible for handling the ajax request/response), using a space-separated list of client IDs, which parts in the HTML DOM tree need to be updated as response to the form submit.

JSF will then prepare the right ajax response for that, containing only the requested parts to update. JSF will skip all other components which are not covered by update attribute in the ajax response, hereby keeping the response payload small. Also, components whose rendered attribute evaluates to false during render response phase will be skipped. Note that even though it would return true, JavaScript cannot update it in the HTML DOM tree if it was initially false. You'd need to wrap it or update its parent instead. See also Ajax update/render does not work on a component which has rendered attribute.

Usually, you'd like to update only the components which really need to be "refreshed" in the client side upon (partial) form submit. The example below updates the entire parent form via @form:

<h:form>
    <p:inputText id="foo" value="#{bean.foo}" required="true" />
    <p:message id="foo_m" for="foo" />
    <p:inputText id="bar" value="#{bean.bar}" required="true" />
    <p:message id="bar_m" for="bar" />
    <p:commandButton action="#{bean.action}" update="@form" />
</h:form>

(note that process attribute is omitted as that defaults to @form already)

Whilst that may work fine, the update of input and command components is in this particular example unnecessary. Unless you change the model values foo and bar inside action method (which would in turn be unintuitive in UX perspective), there's no point of updating them. The message components are the only which really need to be updated:

<h:form>
    <p:inputText id="foo" value="#{bean.foo}" required="true" />
    <p:message id="foo_m" for="foo" />
    <p:inputText id="bar" value="#{bean.bar}" required="true" />
    <p:message id="bar_m" for="bar" />
    <p:commandButton action="#{bean.action}" update="foo_m bar_m" />
</h:form>

However, that gets tedious when you have many of them. That's one of the reasons why PrimeFaces Selectors exist. Those message components have in the generated HTML output a common style class of ui-message, so the following should also do:

<h:form>
    <p:inputText id="foo" value="#{bean.foo}" required="true" />
    <p:message id="foo_m" for="foo" />
    <p:inputText id="bar" value="#{bean.bar}" required="true" />
    <p:message id="bar_m" for="bar" />
    <p:commandButton action="#{bean.action}" update="@(.ui-message)" />
</h:form>

(note that you should keep the IDs on message components, otherwise @(...) won't work! Again, see How do PrimeFaces Selectors as in update="@(.myClass)" work? for detail)

The @parent updates only the parent component, which thus covers the current component and all siblings and their children. This is more useful if you have separated the form in sane groups with each its own responsibility. The @this updates, obviously, only the current component. Normally, this is only necessary when you need to change one of the component's own HTML attributes in the action method. E.g.

<p:commandButton action="#{bean.action}" update="@this" 
    oncomplete="doSomething('#{bean.value}')" />

Imagine that the oncomplete needs to work with the value which is changed in action, then this construct wouldn't have worked if the component isn't updated, for the simple reason that oncomplete is part of generated HTML output (and thus all EL expressions in there are evaluated during render response).

The @all updates the entire document, which should be used with care. Normally, you'd like to use a true GET request for this instead by either a plain link (<a> or <h:link>) or a redirect-after-POST by ?faces-redirect=true or ExternalContext#redirect(). In effects, process="@form" update="@all" has exactly the same effect as a non-ajax (non-partial) submit. In my entire JSF career, the only sensible use case I encountered for @all is to display an error page in its entirety in case an exception occurs during an ajax request. See also What is the correct way to deal with JSF 2.0 exceptions for AJAXified components?

The standard JSF equivalent to the PrimeFaces specific update is render from <f:ajax render>. It behaves exactly the same except that it doesn't support a comma-separated string while the PrimeFaces one does (although I personally recommend to just stick to space-separated convention), nor the @parent keyword. Both update and render defaults to @none (which is, "nothing").

This one worked for me.

Don't agree with post above. I have a Hero with only English available and I want Spanish.

I installed MoreLocale 2, and it has lots of different languages (Dutch among them). I choose Spanish, Sense UI restarted and EVERYTHING in my phone changed to Spanish: menus, settings, etc. The keyboard predictive text defaulted to Spanish and started suggesting words in Spanish. This means, somewhere within the OS there is a Spanish dictionary hidden and MoreLocale made it available.

The problem is that English is still the only option available in keyboard input language so I can switch to English but can't switch back to Spanish unless I restart Sense UI, which takes a couple of minutes so not a very practical solution.

Still looking for an easier way to do it so please help.

HTTP does not place a predefined limit on the length of each header field or on the length of the header section as a whole, as described in Section 2.5. Various ad hoc limitations on individual header field length are found in practice, often depending on the specific field semantics.

HTTP Header values are restricted by server implementations. Http specification doesn't restrict header size.

A server that receives a request header field, or set of fields, larger than it wishes to process MUST respond with an appropriate 4xx (Client Error) status code. Ignoring such header fields would increase the server's vulnerability to request smuggling attacks (Section 9.5).

Most servers will return 413 Entity Too Large or appropriate 4xx error when this happens.

A client MAY discard or truncate received header fields that are larger than the client wishes to process if the field semantics are such that the dropped value(s) can be safely ignored without changing the message framing or response semantics.

Uncapped HTTP header size keeps the server exposed to attacks and can bring down its capacity to serve organic traffic.

I used a combination of the above solutions and some trial and error to come to this solution. Took me an annoying amount of time so I hope this can help someone else in the future. I also noticed that the date picker input is not at all supported by Safari...

I am using styled-components to render a transparent date picker input as shown in the image below:

const StyledInput = styled.input`
  appearance: none;
  box-sizing: border-box;
  border: 1px solid black;
  background: transparent;
  font-size: 1.5rem;
  padding: 8px;
  ::-webkit-datetime-edit-text { padding: 0 2rem; }
  ::-webkit-datetime-edit-month-field { text-transform: uppercase; }
  ::-webkit-datetime-edit-day-field { text-transform: uppercase; }
  ::-webkit-datetime-edit-year-field { text-transform: uppercase; }
  ::-webkit-inner-spin-button { display: none; }
  ::-webkit-calendar-picker-indicator { background: transparent;}

Make sure you import MaterialModule as well since you are using md-input which does not belong to FormsModule

Result is shown in the following code as column number (8,9 etc.):

Dim lastColumn As Long
lastColumn = Sheet1.Cells(1, Columns.Count).End(xlToLeft).Column
MsgBox lastColumn

Result is shown in the following code as letter (H,I etc.):

Dim lastColumn As Long
lastColumn = Sheet1.Cells(1, Columns.Count).End(xlToLeft).Column
MsgBox Split(Sheet1.Cells(1, lastColumn).Address, "$")(1)

Here is a csv file example with 2 columns

myTooth.csv

Date,Tooth
2017-01-25,wisdom
2017-02-19,canine
2017-02-24,canine
2017-02-28,wisdom

To get the first column, use:

cut -d, -f1 myTooth.csv

f stands for Field and d stands for delimiter

Running the above command will produce the following output.

Output

Date
2017-01-25
2017-02-19
2017-02-24
2017-02-28

To get the 2nd column only:

cut -d, -f2 myTooth.csv

And here is the output Output

Tooth
wisdom
canine
canine
wisdom
incisor

Another use case:

Your csv input file contains 10 columns and you want columns 2 through 5 and columns 8, using comma as the separator".

cut uses -f (meaning "fields") to specify columns and -d (meaning "delimiter") to specify the separator. You need to specify the latter because some files may use spaces, tabs, or colons to separate columns.

cut -f 2-5,8 -d , myvalues.csv

cut is a command utility and here is some more examples:

SYNOPSIS
     cut -b list [-n] [file ...]
     cut -c list [file ...]
     cut -f list [-d delim] [-s] [file ...]

Be advised this answer is three years old. I wrote it based mostly on a experience with .Net 4.0, and very little with 4.5 especially with async-await. Generally speaking it's a nice simple solution, but it sometimes breaks things. Please read the discussion in the comments.

.Net 4.5

Just use this:

// For Task<T>: will block until the task is completed...
var result = task.Result; 

// For Task (not Task<T>): will block until the task is completed...
task2.RunSynchronously();

See: TaskAwaiter, Task.Result, Task.RunSynchronously

.Net 4.0

Use this:

var x = (IAsyncResult)task;
task.Start();

x.AsyncWaitHandle.WaitOne();

...or this:

task.Start();
task.Wait();

Kindly ensure, the other columns are not constrained to accept Not null values, hence while creating columns in table just ignore "Not Null" syntax. eg

Create Table Table_Name(
            col1 DataType,
            col2 DataType);

You can then insert multiple row values in any of the columns you want to. For instance:

Insert Into TableName(columnname)
values
      (x),
      (y),
      (z);

and so on…

Hope this helps.

The usual method I have seen is X.Y.Z, which generally corresponds to major.minor.patch:

• Major version numbers change whenever there is some significant change being introduced. For example, a large or potentially backward-incompatible change to a software package.
• Minor version numbers change when a new, minor feature is introduced or when a set of smaller features is rolled out.
• Patch numbers change when a new build of the software is released to customers. This is normally for small bug-fixes or the like.

Other variations use build numbers as an additional identifier. So you may have a large number for X.Y.Z.build if you have many revisions that are tested between releases. I use a couple of packages that are identified by year/month or year/release. Thus, a release in the month of September of 2010 might be 2010.9 or 2010.3 for the 3rd release of this year.

There are many variants to versioning. It all boils down to personal preference.

For the "1.3v1.1", that may be two different internal products, something that would be a shared library / codebase that is rev'd differently from the main product; that may indicate version 1.3 for the main product, and version 1.1 of the internal library / package.

In ORACLE: UNION does not support BLOB (or CLOB) column types, UNION ALL does.

Would it be possible to leave the ability to right click and download just when done a separate watermark is placed on the image. Of course this won't prevent screen shots but thought it may be a good middle ground.

There's an even simpler answer if you want to delete ALL your tables. You just go to your folder containing the database (which may be called mydatabase.db) and right-click the .db file and push "delete." Old fashioned way, sure-fire to work.

Both are supported. To quote the Arduino homepage,

The core libraries are written in C and C++ and compiled using avr-gcc

Note that C++ is a superset of C (well, almost), and thus can often look very similar. I am not an expert, but I guess that most of what you will program for the Arduino in your first year on that platform will not need anything but plain C.

Next, you have to create the .pfx file that you will use to sign your deployments. Open a Command Prompt window, and type the following command:

PVK2PFX –pvk yourprivatekeyfile.pvk –spc yourcertfile.cer –pfx yourpfxfile.pfx –po yourpfxpassword

where:

• pvk - yourprivatekeyfile.pvk is the private key file that you created in step 4.
• spc - yourcertfile.cer is the certificate file you created in step 4.
• pfx - yourpfxfile.pfx is the name of the .pfx file that will be creating.
• po - yourpfxpassword is the password that you want to assign to the .pfx file. You will be prompted for this password when you add the .pfx file to a project in Visual Studio for the first time.

(Optionally (and not for the OP, but for future readers), you can create the .cer and .pvk file from scratch) (you would do this BEFORE the above). Note the mm/dd/yyyy are placeholders for start and end dates. see msdn article for full documentation.

x = (y/150) * 72                (2) for 150dpi system

so:

points = (pixels / 150) * 72    (3) for 150dpi system

For PHP's PHPSESSID variable, this function works:

function getPHPSessId() {
    var phpSessionId = document.cookie.match(/PHPSESSID=[A-Za-z0-9]+\;/i);

    if(phpSessionId == null) 
        return '';

    if(typeof(phpSessionId) == 'undefined')
        return '';

    if(phpSessionId.length <= 0)
        return '';

    phpSessionId = phpSessionId[0];

    var end = phpSessionId.lastIndexOf(';');
    if(end == -1) end = phpSessionId.length;

    return phpSessionId.substring(10, end);
}

For large dataframes of numeric data, you may see a significant performance improvement via numpy.lexsort, which performs an indirect sort using a sequence of keys:

import pandas as pd
import numpy as np

np.random.seed(0)

df1 = pd.DataFrame(np.random.randint(1, 5, (10,2)), columns=['a','b'])
df1 = pd.concat([df1]*100000)

def pdsort(df1):
    return df1.sort_values(['a', 'b'], ascending=[True, False])

def lex(df1):
    arr = df1.values
    return pd.DataFrame(arr[np.lexsort((-arr[:, 1], arr[:, 0]))])

assert (pdsort(df1).values == lex(df1).values).all()

%timeit pdsort(df1)  # 193 ms per loop
%timeit lex(df1)     # 143 ms per loop

One peculiarity is that the defined sorting order with numpy.lexsort is reversed: (-'b', 'a') sorts by series a first. We negate series b to reflect we want this series in descending order.

Be aware that np.lexsort only sorts with numeric values, while pd.DataFrame.sort_values works with either string or numeric values. Using np.lexsort with strings will give: TypeError: bad operand type for unary -: 'str'.

Here is an option using a for loop by groups rather by rows (like OP did)

for (i in unique(df$cat)) df$num[df$cat == i] <- seq_len(sum(df$cat == i))

From PEP 8, in the “Programming Recommendations” section:

For sequences, (strings, lists, tuples), use the fact that empty sequences are false.

So you should use:

if not some_string:

or:

if some_string:

Just to clarify, sequences are evaluated to False or True in a Boolean context if they are empty or not. They are not equal to False or True.

Documentation says it's just a shortcut for creating readonly properties. So

@property
def x(self):
    return self._x

is equivalent to

def getx(self):
    return self._x
x = property(getx)

I have added code for onclick event value pass to the method in two ways . 1 . using bind method 2. using arrow(=>) method . see the methods handlesort1 and handlesort

var HeaderRows  = React.createClass({
    getInitialState : function() {
      return ({
        defaultColumns : ["col1","col2","col2","col3","col4","col5" ],
        externalColumns : ["ecol1","ecol2","ecol2","ecol3","ecol4","ecol5" ],

      })
    },
    handleSort:  function(column,that) {
       console.log(column);
       alert(""+JSON.stringify(column));
    },
    handleSort1:  function(column) {
       console.log(column);
       alert(""+JSON.stringify(column));
    },
    render: function () {
        var that = this;
        return(
        <div>
            <div>Using bind method</div>
            {this.state.defaultColumns.map(function (column) {
                return (
                    <div value={column} style={{height : '40' }}onClick={that.handleSort.bind(that,column)} >{column}</div>
                );
            })}
            <div>Using Arrow method</div>

            {this.state.defaultColumns.map(function (column) {
                return (

                );
            })}
            {this.state.externalColumns.map(function (column) {
                // Multi dimension array - 0 is column name
                var externalColumnName = column;
                return (<div><span>{externalColumnName}</span></div>
                );
            })}

        </div>);
    }
});

function hex2a(hexx) {
    var hex = hexx.toString();//force conversion
    var str = '';
    for (var i = 0; (i < hex.length && hex.substr(i, 2) !== '00'); i += 2)
        str += String.fromCharCode(parseInt(hex.substr(i, 2), 16));
    return str;
}
hex2a('32343630'); // returns '2460'
