As you can see in the templates, the text is delivered via the localization framework (note the use of the trans template tag). You can make changes to the translation files to override the text without making your own copy of the templates.

1. mkdir locale

2. ./manage.py makemessages

3. Edit locale/en/LC_MESSAGES/django.po, adding these lines:

   msgid "Django site admin"
   msgstr "MySite site admin"
   
   msgid "Django administration"
   msgstr "MySite administration"
   

4. ./manage.py compilemessages

See https://docs.djangoproject.com/en/1.3/topics/i18n/localization/#message-files

I basically follow this pattern:

• start from 0.1.0

• when it's ready I branch the code in the source repo, tag 0.1.0 and create the 0.1.0 branch, the head/trunk becomes 0.2.0-snapshot or something similar

• I add new features only to the trunk, but backport fixes to the branch and in time I release from it 0.1.1, 0.1.2, ...

• I declare version 1.0.0 when the product is considered feature complete and doesn't have major shortcomings

• from then on - everyone can decide when to increment the major version...

Your second question is easy, GET has a size limitation of 1-2 kilobytes on both the server and browser side, so any kind of larger amounts of data you'd have to send through POST.

In ES6, imports are live read-only views on exported-values. As a result, when you do import a from "somemodule";, you cannot assign to a no matter how you declare a in the module.

However, since imported variables are live views, they do change according to the "raw" exported variable in exports. Consider the following code (borrowed from the reference article below):

//------ lib.js ------
export let counter = 3;
export function incCounter() {
    counter++;
}

//------ main1.js ------
import { counter, incCounter } from './lib';

// The imported value `counter` is live
console.log(counter); // 3
incCounter();
console.log(counter); // 4

// The imported value can’t be changed
counter++; // TypeError

As you can see, the difference really lies in lib.js, not main1.js.

To summarize:

• You cannot assign to import-ed variables, no matter how you declare the corresponding variables in the module.
• The traditional let-vs-const semantics applies to the declared variable in the module.
  • If the variable is declared const, it cannot be reassigned or rebound in anywhere.
  • If the variable is declared let, it can only be reassigned in the module (but not the user). If it is changed, the import-ed variable changes accordingly.

Django 2.2+

Using the constraints features UniqueConstraint is preferred over unique_together.

From the Django documentation for unique_together:

Use UniqueConstraint with the constraints option instead.
UniqueConstraint provides more functionality than unique_together.
unique_together may be deprecated in the future.

For example:

class Volume(models.Model):
    id = models.AutoField(primary_key=True)
    journal_id = models.ForeignKey(Journals, db_column='jid', null=True, verbose_name="Journal")
    volume_number = models.CharField('Volume Number', max_length=100)
    comments = models.TextField('Comments', max_length=4000, blank=True)

    class Meta:
        constraints = [
            models.UniqueConstraint(fields=['journal_id', 'volume_number'], name='name of constraint')
        ]

mputty can do that but it does not seem to work always. (if that wait period is too slow)

mputty uses putty and it extends putty. There is an option to run a script. If it does not work, make sure that wait period before typing is a high value or increase that value. See putty sessions , then name of session, right mouse button,properties/script page.

Create two partial indexes:

CREATE UNIQUE INDEX favo_3col_uni_idx ON favorites (user_id, menu_id, recipe_id)
WHERE menu_id IS NOT NULL;

CREATE UNIQUE INDEX favo_2col_uni_idx ON favorites (user_id, recipe_id)
WHERE menu_id IS NULL;

This way, there can only be one combination of (user_id, recipe_id) where menu_id IS NULL, effectively implementing the desired constraint.

Possible drawbacks: you cannot have a foreign key referencing (user_id, menu_id, recipe_id), you cannot base CLUSTER on a partial index, and queries without a matching WHERE condition cannot use the partial index. (It seems unlikely you'd want a FK reference three columns wide - use the PK column instead).

If you need a complete index, you can alternatively drop the WHERE condition from favo_3col_uni_idx and your requirements are still enforced.
The index, now comprising the whole table, overlaps with the other one and gets bigger. Depending on typical queries and the percentage of NULL values, this may or may not be useful. In extreme situations it might even help to maintain all three indexes (the two partial ones and a total on top).

Aside: I advise not to use mixed case identifiers in PostgreSQL.

Simply compare the width of the documents root element (i.e. html element) against the inner portion of the window:

if ((window.innerWidth - document.documentElement.clientWidth) >0) console.log('V-scrollbar active')

If you also need to know the scrollbar width:

vScrollbarWidth = window.innerWidth - document.documentElement.clientWidth;

I had a somehow similar problem working with AFNetworking from a Swift codebase so I'm just leaving this here in the remote case someone is as unlucky as me having to work in such a setup. If you are, I feel you buddy, stay strong!

The operation was failing due to "unacceptable content-type", despite me actually setting the acceptableContentTypes with a Set containing the content type value in question.

The solution for me was to tweak the Swift code to be more Objective-C friendly, I guess:

serializer.acceptableContentTypes = NSSet(array: ["application/xml", "text/xml", "text/plain"]) as Set<NSObject>

1.Very Simple Code to iterate datatable and get columns in list.

2.code ==>>>

 foreach (DataColumn dataColumn in dataTable.Columns)
 {
    var list = dataTable.Rows.OfType<DataRow>()
     .Select(dataRow => dataRow.Field<string> 
       (dataColumn.ToString())).ToList();
 }

This is the only code that worked for me:

for /f "tokens=4" %%G IN ("aaa bbb ccc ddd eee fff") DO echo %%G 

output:

By default, SQL Plus treats '&' as a special character that begins a substitution string. This can cause problems when running scripts that happen to include '&' for other reasons:

SQL> insert into customers (customer_name) values ('Marks & Spencers Ltd');
Enter value for spencers: 
old   1: insert into customers (customer_name) values ('Marks & Spencers Ltd')
new   1: insert into customers (customer_name) values ('Marks  Ltd')

1 row created.

SQL> select customer_name from customers;

CUSTOMER_NAME
------------------------------
Marks  Ltd

If you know your script includes (or may include) data containing '&' characters, and you do not want the substitution behaviour as above, then use set define off to switch off the behaviour while running the script:

SQL> set define off
SQL> insert into customers (customer_name) values ('Marks & Spencers Ltd');

1 row created.

SQL> select customer_name from customers;

CUSTOMER_NAME
------------------------------
Marks & Spencers Ltd

You might want to add set define on at the end of the script to restore the default behaviour.

Since you are not interested in keeping any data, drop the entire database and create a new one.

Assuming I have node and npm properly installed on the machine, I would

• Download the code
• Navigate to inside the project folder on terminal, where I would hopefully see a package.json file
• Do an npm install for installing all the project dependencies
• Do an npm install -g nodemon for installing all the project dependencies
• Then npm start OR node app.js OR nodemon app.js to get the app running on local host

Hope this helps someone

use nodemon app.js ( nodemon is a utility that will monitor for any changes in your source and automatically restart your server)

it is because of using web address, You can not use http to write data. don't use : http:// or https:// in your location for upload files or save data or somting like that. instead of of using $_SERVER["HTTP_REFERER"] use $_SERVER["DOCUMENT_ROOT"]. for example :

wrong :

move_uploaded_file($_FILES["File"]["tmp_name"],$_SERVER["HTTP_REFERER"].'/uploads/images/1.jpg')

correct:

move_uploaded_file($_FILES["File"]["tmp_name"],$_SERVER["DOCUMENT_ROOT"].'/uploads/images/1.jpg')

You can use <hr> for a vertical line as well.
Set the width to 1 and the size(height) as long as you want.
I used 500 in my example(demo):

With <hr width="1" size="500">

many answers above are close, but they get ~username syntax for deploy tokens incorrect. There are other types of tokens, but the deploy token is what gitlab offers (circa 2020+ at least) per repo to allow customized access, including read-only.

from a repository (or group), find the settings --> repository --> deploy tokens. Create a new one. A username and token field are created. The username is NOT a fixed value by default; it's unique to this token.

git clone https://<your_deploy_token_username>:<the_token>@gitlab.com/your/repo/path.git

The better approach will be:

This is CLEANEST, SIMPLEST ANSWER for CONTIGUOUS NON-PRINTING Ruby Code:

The below also happens to answer the Original Poster's question without, the "ugly" conditional code that some commenters have mentioned.

1. CONTIGUOUS NON-PRINTING Ruby Code

   • This will work in any mixed language Rails View file, e.g, *.html.erb, *.js.erb, *.rhtml, etc.

   • This should also work with STD OUT/printing code, e.g. <%#= f.label :title %>

   • DETAILS:

     Rather than use rails brackets on each line and commenting in front of each starting bracket as we usually do like this:

       <%# if flash[:myErrors] %>
         <%# if flash[:myErrors].any? %>
           <%# if @post.id.nil? %>
             <%# if @myPost!=-1 %>
               <%# @post = @myPost %>
             <%# else %>
               <%# @post = Post.new %>
             <%# end %>
           <%# end %>
         <%# end %>
       <%# end %>
     

     YOU CAN INSTEAD add only one comment (hashmark/poundsign) to the first open Rails bracket if you write your code as one large block... LIKE THIS:

       <%# 
         if flash[:myErrors] then
           if flash[:myErrors].any? then
             if @post.id.nil? then
               if @myPost!=-1 then
                 @post = @myPost 
               else 
                 @post = Post.new 
               end 
             end 
           end 
         end 
       %>
     

I also faced the same problem but I resolved the issue by starting the TNS listener in control panel -> administrative tools -> services ->oracle TNS listener start.I am using windows Xp and Toad to connect to Oracle.

This will print the count first, but other than that it should be exactly what you want.

Probably there's something wrong with the input values for X and/or T. The function from the question works ok:

import numpy as np
from math import e

def sigmoid(X, T):
  return 1.0 / (1.0 + np.exp(-1.0 * np.dot(X, T)))

X = np.array([[1, 2, 3], [5, 0, 0]])
T = np.array([[1, 2], [1, 1], [4, 4]])

print(X.dot(T))
# Just to see if values are ok
print([1. / (1. + e ** el) for el in [-5, -10, -15, -16]])
print()
print(sigmoid(X, T))

Result:

[[15 16]
 [ 5 10]]

[0.9933071490757153, 0.9999546021312976, 0.999999694097773, 0.9999998874648379]

[[ 0.99999969  0.99999989]
 [ 0.99330715  0.9999546 ]]

Probably it's the dtype of your input arrays. Changing X to:

X = np.array([[1, 2, 3], [5, 0, 0]], dtype=object)

Gives:

Traceback (most recent call last):
  File "/[...]/stackoverflow_sigmoid.py", line 24, in <module>
    print sigmoid(X, T)
  File "/[...]/stackoverflow_sigmoid.py", line 14, in sigmoid
    return 1.0 / (1.0 + np.exp(-1.0 * np.dot(X, T)))
AttributeError: exp

It's really a 6 of one, a half-dozen of the other situation.

The only possible argument against your approach is $_SERVER['REQUEST_METHOD'] == 'POST' may not be populated on certain web-servers/configuration, whereas the $_POST array will always exist in PHP4/PHP5 (and if it doesn't exist, you have bigger problems (-:)

Try this instead:

url = 'http://myserver/post_service'
data = urllib.urlencode({'name' : 'joe',
                         'age'  : '10'})
req = urllib2.Request(url=url,data=data)
content = urllib2.urlopen(req).read()
print content

Both certificates should exist prior to the connection. They're usually created by Certification Authorities (not necessarily the same). (There are alternative cases where verification can be done differently, but some verification will need to be made.)

The server certificate should be created by a CA that the client trusts (and following the naming conventions defined in RFC 6125).

The client certificate should be created by a CA that the server trusts.

It's up to each party to choose what it trusts.

There are online CA tools that will allow you to apply for a certificate within your browser and get it installed there once the CA has issued it. They need not be on the server that requests client-certificate authentication.

The certificate distribution and trust management is the role of the Public Key Infrastructure (PKI), implemented via the CAs. The SSL/TLS client and servers and then merely users of that PKI.

When the client connects to a server that requests client-certificate authentication, the server sends a list of CAs it's willing to accept as part of the client-certificate request. The client is then able to send its client certificate, if it wishes to and a suitable one is available.

The main advantages of client-certificate authentication are:

• The private information (the private key) is never sent to the server. The client doesn't let its secret out at all during the authentication.
• A server that doesn't know a user with that certificate can still authenticate that user, provided it trusts the CA that issued the certificate (and that the certificate is valid). This is very similar to the way passports are used: you may have never met a person showing you a passport, but because you trust the issuing authority, you're able to link the identity to the person.

When working with Angular the recent update to Angular 8 introduced that a static property inside @ViewChild() is required as stated here and here. Then your code would require this small change:

@ViewChild('one') d1:ElementRef;

into

// query results available in ngOnInit
@ViewChild('one', {static: true}) foo: ElementRef;

OR

// query results available in ngAfterViewInit
@ViewChild('one', {static: false}) foo: ElementRef;

I know this has already been answered, but still, this is a good way to do it:

if ($("#checkbox").is(":checked")==false) {
    //Do stuff here like: $(".span").html("<span>Lorem</span>");
}

Please change small "mm" month to capital "MM" it will work.for reference below is the sample code.

        Date myDate = new Date();
        SimpleDateFormat sm = new SimpleDateFormat("MM-dd-yyyy");
       
        String strDate = sm.format(myDate);
        
        Date dt = sm.parse(strDate);
        System.out.println(strDate);

Because it's all just about memory, in the end all the numerical values are stored in binary.

A 32 bit unsigned integer can contain values from all binary 0s to all binary 1s.

When it comes to 32 bit signed integer, it means one of its bits (most significant) is a flag, which marks the value to be positive or negative.

Adding overflow:auto before setting overflow-y seems to do the trick in Google Chrome.

{
    width:249px;
    height:299px;
    background-color:Gray;
    overflow: auto;
    overflow-y: scroll;
    max-width:230px;
    max-height:100px;
}

depending on how many columns there are, you could just name the columns, sans the ID, and manually add an ID or, if it's in your table, a secondary ID (sid):

insert into PROG(date, level, Percent, sid) select date, level, Percent, 55 from PROG where sid = 31 Here, if sid 31 has more than one resultant row, all of them will be copied over to sid 55 and your auto iDs will still get auto-generated. for ID only: insert into PROG(date, level, Percent, ID) select date, level, Percent, 55 from PROG where ID = 31 where 55 is the next available ID in the table and ID 31 is the one you want to copy.

uint16_t is guaranteed to be a unsigned integer that is 16 bits large

unsigned short int is guaranteed to be a unsigned short integer, where short integer is defined by the compiler (and potentially compiler flags) you are currently using. For most compilers for x86 hardware a short integer is 16 bits large.

Also note that per the ANSI C standard only the minimum size of 16 bits is defined, the maximum size is up to the developer of the compiler

Minimum Type Limits

Any compiler conforming to the Standard must also respect the following limits with respect to the range of values any particular type may accept. Note that these are lower limits: an implementation is free to exceed any or all of these. Note also that the minimum range for a char is dependent on whether or not a char is considered to be signed or unsigned.

Type Minimum Range

signed char     -127 to +127
unsigned char      0 to 255
short int     -32767 to +32767
unsigned short int 0 to 65535

The registry/configurationSettings/XML argument still seems very active. I've used them all, as the technology has progressed, but my favourite is based on Threed's system combined with Isolated Storage.

The following sample allows storage of an objects named properties to a file in isolated storage. Such as:

AppSettings.Save(myobject, "Prop1,Prop2", "myFile.jsn");

Properties may be recovered using:

AppSettings.Load(myobject, "myFile.jsn");

It is just a sample, not suggestive of best practices.

internal static class AppSettings
{
    internal static void Save(object src, string targ, string fileName)
    {
        Dictionary<string, object> items = new Dictionary<string, object>();
        Type type = src.GetType();

        string[] paramList = targ.Split(new char[] { ',' });
        foreach (string paramName in paramList)
            items.Add(paramName, type.GetProperty(paramName.Trim()).GetValue(src, null));

        try
        {
            // GetUserStoreForApplication doesn't work - can't identify.
            // application unless published by ClickOnce or Silverlight

            {

This function creates a temporary form, then send data using jQuery :

function postToIframe(data,url,target){
    $('body').append('<form action="'+url+'" method="post" target="'+target+'" id="postToIframe"></form>');
    $.each(data,function(n,v){
        $('#postToIframe').append('<input type="hidden" name="'+n+'" value="'+v+'" />');
    });
    $('#postToIframe').submit().remove();
}

target is the 'name' attr of the target iFrame, and data is a JS object :

data={last_name:'Smith',first_name:'John'}

The answer is NO, but...

You may confused because of the behavior of fgets()

From http://www.cplusplus.com/reference/cstdio/fgets/ :

Reads characters from stream and stores them as a C string into str until (num-1) characters have been read or either a newline or the end-of-file is reached, whichever happens first.

Download codeblocks-13.12mingw-setup.exe instead of codeblocks-13.12setup.exe from the official site. Here 13.12 is the latest version so far.

Had similar problem with the SVN 1.6.5 on Mac 10.6.5, upgraded to SVN 1.6.9 and the commit succeeded.

You would have to open a new window(or navigate to a new page) containing just the information you wish the user to be able to print

Javscript:

function printInfo(ele) {
    var openWindow = window.open("", "title", "attributes");
    openWindow.document.write(ele.previousSibling.innerHTML);
    openWindow.document.close();
    openWindow.focus();
    openWindow.print();
    openWindow.close();
}

HTML:

<div id="....">
    <div>
        content to print
    </div><a href="#" onclick="printInfo(this)">Print</a>
</div>

A few notes here: the anchor must NOT have whitespace between it and the div containing the content to print

to check if url is online or offline ---

function get_http_response_code($theURL) {
    $headers = @get_headers($theURL);
    return substr($headers[0], 9, 3);
}

specky.vim

getActivity().getSupportFragmentManager().beginTransaction().replace(GeneralInfo.this.getId(), new GeneralInfo()).commit();

GeneralInfo it's my Fragment class GeneralInfo.java

I put it as a method in the fragment class:

public void Reload(){
    getActivity().getSupportFragmentManager().beginTransaction().replace(LogActivity.this.getId(), new LogActivity()).commit();
}

Just want to reiterate this will work in pandas >= 0.9.1:

In [2]: read_csv('sample.csv', dtype={'ID': object})
Out[2]: 
                           ID
0  00013007854817840016671868
1  00013007854817840016749251
2  00013007854817840016754630
3  00013007854817840016781876
4  00013007854817840017028824
5  00013007854817840017963235
6  00013007854817840018860166

I'm creating an issue about detecting integer overflows also.

EDIT: See resolution here: https://github.com/pydata/pandas/issues/2247

Update as it helps others:

To have all columns as str, one can do this (from the comment):

pd.read_csv('sample.csv', dtype = str)

To have most or selective columns as str, one can do this:

# lst of column names which needs to be string
lst_str_cols = ['prefix', 'serial']
# use dictionary comprehension to make dict of dtypes
dict_dtypes = {x : 'str'  for x in lst_str_cols}
# use dict on dtypes
pd.read_csv('sample.csv', dtype=dict_dtypes)

For Visual Studio, in the package manager console:

 drop-database

If you just want to inspect the variables manually to help debug, just fire up the debugger:

debugger;

Straight into the browser console.

This issue is not because of corrupt database. I found the solution from this video - https://www.youtube.com/watch?v=MqOsp54EA3I

It is suggested to increase the values of two variables in php.ini file. Change following in php.ini

upload_max_filesize=64M
post_max_size=64M

Then restart the server.

This solved my issue. Hope solves yours too.

Yes this is good. Tutorials are not always consize and neat. Not only that, creating local variables is waste of space and inefficient

The same problem happened to me using PostgreSQL I cleared all migrations in migrations folder and in migrations cache folder, and then in my PGADMIN ran:

delete from django_migrations where app='your_app'

Whatever I understood from my learning and what I think it is is here. I am Quoting some part from a book i learnt this things. Nexus Repository Manager and Nexus Repository Manager OSS started as a repository manager supporting the Maven repository format. While it supports many other repository formats now, the Maven repository format is still the most common and well supported format for build and provisioning tools running on the JVM and beyond. This chapter shows example configurations for using the repository manager with Apache Maven and a number of other tools. The setups take advantage of merging many repositories and exposing them via a repository group. Setting this up is documented in the chapter in addition to the configuration used by specific tools.

Details

I was trying a hello world program, and this line:

#include <stdio.h>

was underlined green. I tried:

1. Deleting the line
2. Re-writing the line
3. Clicking the yellow bulb and choosing to update

fixed the error warning. i don't know if it fixed the actual problem. But then i'm compiling via a linux VM on Windows 10

Using writeLines also allows you to dispense with the "\n" newline character, by using c(). As in:

writeLines(c("File not supplied.","Usage: ./program F=filename",[additional text for third line]))

This is helpful if you plan on writing a multiline message with combined fixed and variable input, such as the [additional text for third line] above.

You must set proxy server for gradle at some time, you can try to change the proxy server ip address in gradle.properties which is under .gradle document

Instead of returning StreamContent as the Content, I can make it work with ByteArrayContent.

[HttpGet]
public HttpResponseMessage Generate()
{
    var stream = new MemoryStream();
    // processing the stream.

    var result = new HttpResponseMessage(HttpStatusCode.OK)
    {
        Content = new ByteArrayContent(stream.ToArray())
    };
    result.Content.Headers.ContentDisposition =
        new System.Net.Http.Headers.ContentDispositionHeaderValue("attachment")
    {
        FileName = "CertificationCard.pdf"
    };
    result.Content.Headers.ContentType =
        new MediaTypeHeaderValue("application/octet-stream");

    return result;
}

Here is a little more fun. I've found that very often NumPy does exactly what I wish it would do - sometimes it's faster for me to just try things than it is to read the docs. Actually a mixture of both is best.

I think your answer is fine (and it's OK to accept it if you like). This is just "extra".

import numpy as np

a = np.arange(4,10).reshape(2,3)

wh = np.where(a>7)
gt = a>7
x  = np.where(gt)

print "wh: ", wh
print "gt: ", gt
print "x:  ", x

gives:

wh:  (array([1, 1]), array([1, 2]))
gt:  [[False False False]
      [False  True  True]]
x:   (array([1, 1]), array([1, 2]))

... but:

print "a[wh]: ", a[wh]
print "a[gt]  ", a[gt]
print "a[x]:  ", a[x]

gives:

a[wh]:  [8 9]
a[gt]   [8 9]
a[x]:   [8 9]

You can convert CSV string to Array with this function.

    function csv2array(
        $csv_string,
        $delimiter = ",",
        $skip_empty_lines = true,
        $trim_fields = true,
        $FirstLineTitle = false
    ) {
        $arr = array_map(
            function ( $line ) use ( &$result, &$FirstLine, $delimiter, $trim_fields, $FirstLineTitle ) {
                if ($FirstLineTitle && !$FirstLine) {
                    $FirstLine = explode( $delimiter, $result[0] );
                }
                $lineResult = array_map(
                    function ( $field ) {
                        return str_replace( '!!Q!!', '"', utf8_decode( urldecode( $field ) ) );
                    },
                    $trim_fields ? array_map( 'trim', explode( $delimiter, $line ) ) : explode( $delimiter, $line )
                );
                return $FirstLineTitle ? array_combine( $FirstLine, $lineResult ) : $lineResult;
            },
            ($result = preg_split(
                $skip_empty_lines ? ( $trim_fields ? '/( *\R)+/s' : '/\R+/s' ) : '/\R/s',
                preg_replace_callback(
                    '/"(.*?)"/s',
                    function ( $field ) {
                        return urlencode( utf8_encode( $field[1] ) );
                    },
                    $enc = preg_replace( '/(?<!")""/', '!!Q!!', $csv_string )
                )
            ))
        );
        return $FirstLineTitle ? array_splice($arr, 1) : $arr;
    }

I found very good explanation about .la files here http://openbooks.sourceforge.net/books/wga/dealing-with-libraries.html

Summary (The way I understood): Because libtool deals with static and dynamic libraries internally (through --diable-shared or --disable-static) it creates a wrapper on the library files it builds. They are treated as binary library files with in libtool supported environment.

Here's an expression that works for MariaDB and MySQL >= 5.6:

SELECT (UNIX_TIMESTAMP(NOW()) * 1000000 + MICROSECOND(NOW(6))) AS unix_now_in_microseconds;

This relies on the fact that NOW() always returns the same time throughout a query; it's possible that a plain UNIX_TIMESTAMP() would work as well, I'm not sure based on the documentation. It also requires MySQL >= 5.6 for the new precision argument for NOW() function (MariaDB works too).

The other answers gave me the right clues, but they didn't completely help.

Here's what worked for me:

$ git checkout email
$ git tag old-email-branch # This is optional
$ git reset --hard staging
$
$ # Using a custom commit message for the merge below
$ git merge -m 'Merge -s our where _ours_ is the branch staging' -s ours origin/email
$ git push origin email

Without the fourth step of merging with the ours strategy, the push is considered a non-fast-forward update and will be rejected (by GitHub).

I know this is a way late, but I thought I'd add yet another way of doing this.

You can take advantage of the fact that the Text property can be set using "Runs", so you can set up multiple bindings using a Run for each one. This is useful if you don't have access to MultiBinding (which I didn't find when developing for Windows Phone)

<TextBlock>
  <Run Text="Name = "/>
  <Run Text="{Binding Name}"/>
  <Run Text=", Id ="/>
  <Run Text="{Binding Id}"/>
</TextBlock>

I think you just need;

List<string> list = new List<string>();
list.Add("hai");

There is a difference between

List<string> list; 

and

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

When you didn't use new keyword in this case, your list didn't initialized. And when you try to add it hai, obviously you get an error.

Edit the tty configuration in /etc/init/tty*.conf with a shellscript as a parameter :

(...)
exec /sbin/getty -n -l  theInputScript.sh -8 38400 tty1
(...)

This is assuming that we're editing tty1 and the script that reads input is theInputScript.sh.

A word of warning this script is run as root, so when you are inputing stuff to it you have root priviliges. Also append a path to the location of the script.

Important: the script when it finishes, has to invoke the /sbin/login otherwise you wont be able to login in the terminal.

Yes you can start with the Wikipedia article explaining the Big O notation, which in a nutshell is a way of describing the "efficiency" (upper bound of complexity) of different type of algorithms. Or you can look at an earlier answer where this is explained in simple english

A stable version of this function looks like this:

// not defined for empty array
function max_index(elements) {
    var i = 1;
    var mi = 0;
    while (i < elements.length) {
        if (!(elements[i] < elements[mi]))
            mi = i;
        i += 1;
    }
    return mi;
}

Math.Floor() rounds toward negative infinity

Math.Truncate rounds up or down towards zero.

For example:

Math.Floor(-3.4)     = -4
Math.Truncate(-3.4)  = -3

while

Math.Floor(3.4)     = 3
Math.Truncate(3.4)  = 3

the answer is already exist above, but I would like to add some thing.. you can specify the following in your @font-face

@font-face {
  font-family: 'Name You Font';
  src: url('assets/font/xxyourfontxxx.eot');
  src: local('Cera Pro Medium'), local('CeraPro-Medium'),
  url('assets/font/xxyourfontxxx.eot?#iefix') format('embedded-opentype'),
  url('assets/font/xxyourfontxxx.woff') format('woff'),
  url('assets/font/xxyourfontxxx.ttf') format('truetype');
  font-weight: 500;
  font-style: normal;
}

So you can just indicate your fontfamily name that you already choosed

NOTE: the font-weight and font-style depend on your .woff .ttf ... files

<html>
<head>

$(function() {

    //here you have the control over the body of the iframe document
    var iBody = $("#iView").contents().find("body");

    //here you have the control over any element (#myContent)
    var myContent = iBody.find("#myContent");

});

</script>

<body>
  <iframe src="mifile.html" id="iView" style="width:200px;height:70px;border:dotted 1px red" frameborder="0"></iframe>

you can also create your own interface as well.

    export interface UserEvent {
      target: HTMLInputElement;
    }

       ...

    onUpdatingServerName(event: UserEvent) {
      .....
    }

Here is an simple implementation using javascript which is based on the conversion of latitude degree to kms where 1 degree latitude ~ 111.2 km.

I am calculating bounds of the map from a given latitude, longitude and radius in kilometers.

function getBoundsFromLatLng(lat, lng, radiusInKm){
     var lat_change = radiusInKm/111.2;
     var lon_change = Math.abs(Math.cos(lat*(Math.PI/180)));
     var bounds = { 
         lat_min : lat - lat_change,
         lon_min : lng - lon_change,
         lat_max : lat + lat_change,
         lon_max : lng + lon_change
     };
     return bounds;
}

if you wanna have an DateArray with dates try this:

<script>
        function getDates(startDate, stopDate) {
        var dateArray = new Array();
        var currentDate = moment(startDate);
        dateArray.push( moment(currentDate).format('L'));

        var stopDate = moment(stopDate);
        while (dateArray[dateArray.length -1] != stopDate._i) {
            dateArray.push( moment(currentDate).format('L'));
            currentDate = moment(currentDate).add(1, 'days');
        }
        return dateArray;
      }
</script>

DebugSnippet

Events are pretty easy in C#, but the MSDN docs in my opinion make them pretty confusing. Normally, most documentation you see discusses making a class inherit from the EventArgs base class and there's a reason for that. However, it's not the simplest way to make events, and for someone wanting something quick and easy, and in a time crunch, using the Action type is your ticket.

Creating Events & Subscribing To Them

1. Create your event on your class right after your class declaration.

public event Action<string,string,string,string>MyEvent;

2. Create your event handler class method in your class.

private void MyEventHandler(string s1,string s2,string s3,string s4)
{
  Console.WriteLine("{0} {1} {2} {3}",s1,s2,s3,s4);
}

3. Now when your class is invoked, tell it to connect the event to your new event handler. The reason the += operator is used is because you are appending your particular event handler to the event. You can actually do this with multiple separate event handlers, and when an event is raised, each event handler will operate in the sequence in which you added them.

class Example
{
  public Example() // I'm a C# style class constructor
  {
    MyEvent += new Action<string,string,string,string>(MyEventHandler);
  }
}

4. Now, when you're ready, trigger (aka raise) the event somewhere in your class code like so:

MyEvent("wow","this","is","cool");

The end result when you run this is that the console will emit "wow this is cool". And if you changed "cool" with a date or a sequence, and ran this event trigger multiple times, you'd see the result come out in a FIFO sequence like events should normally operate.

In this example, I passed 4 strings. But you could change those to any kind of acceptable type, or used more or less types, or even remove the <...> out and pass nothing to your event handler.

And, again, if you had multiple custom event handlers, and subscribed them all to your event with the += operator, then your event trigger would have called them all in sequence.

Identifying Event Callers

But what if you want to identify the caller to this event in your event handler? This is useful if you want an event handler that reacts with conditions based on who's raised/triggered the event. There are a few ways to do this. Below are examples that are shown in order by how fast they operate:

Option 1. (Fastest) If you already know it, then pass the name as a literal string to the event handler when you trigger it.

Option 2. (Somewhat Fast) Add this into your class and call it from the calling method, and then pass that string to the event handler when you trigger it:

private static string GetCaller([System.Runtime.CompilerServices.CallerMemberName] string s = null) => s;

Option 3. (Least Fast But Still Fast) In your event handler when you trigger it, get the calling method name string with this:

string callingMethod = new System.Diagnostics.StackTrace().GetFrame(1).GetMethod().ReflectedType.Name.Split('<', '>')[1];

Unsubscribing From Events

You may have a scenario where your custom event has multiple event handlers, but you want to remove one special one out of the list of event handlers. To do so, use the -= operator like so:

MyEvent -= MyEventHandler;

A word of minor caution with this, however. If you do this and that event no longer has any event handlers, and you trigger that event again, it will throw an exception. (Exceptions, of course, you can trap with try/catch blocks.)

Clearing All Events

Okay, let's say you're through with events and you don't want to process any more. Just set it to null like so:

MyEvent = null;

The same caution for Unsubscribing events is here, as well. If your custom event handler no longer has any events, and you trigger it again, your program will throw an exception.

Possible this be helpful for you. This script generate indexes, FK's, PK and common structure for any table.

How to Generate a CREATE TABLE Script For an Existing Table: Part 1

Always use new in C++. If you need a block of untyped memory, you can use operator new directly:

void *p = operator new(size);
   ...
operator delete(p);

var img = new Image();

img.onload = function(){
  var height = img.height;
  var width = img.width;

  // code here to use the dimensions
}

img.src = url;

As the instructions state, using the open() function does work, and opens the default web browser - usually I would say: "why wouldn't I want to use Firefox?!" (my default and favorite browser)

import webbrowser as wb
wb.open_new_tab('http://www.google.com')

The above should work for the computer's default browser. However, what if you want to to open in Google Chrome?

The proper way to do this is:

import webbrowser as wb
wb.get('chrome %s').open_new_tab('http://www.google.com')

To be honest, I'm not really sure that I know the difference between 'chrome' and 'google-chrome', but apparently there is some since they've made the two different type names in the webbrowser documentation.

However, doing this didn't work right off the bat for me. Every time, I would get the error:

Traceback (most recent call last):
File "C:\Python34\programs\a_temp_testing.py", line 3, in <module>
wb.get('google-chrome')
File "C:\Python34\lib\webbrowser.py", line 51, in get
raise Error("could not locate runnable browser")
webbrowser.Error: could not locate runnable browser

To solve this, I had to add the folder for chrome.exe to System PATH. My chrome.exe executable file is found at:

C:\Program Files (x86)\Google\Chrome\Application

You should check whether it is here or not for yourself.

To add this to your Environment Variables System PATH, right click on your Windows icon and go to System. System Control Panel applet (Start - Settings - Control Panel - System). Change advanced settings, or the advanced tab, and select the button there called Environment Varaibles.

Once you click on Environment Variables here, another window will pop up. Scroll through the items, select PATH, and click edit.

Once you're in here, click New to add the folder path to your chrome.exe file. Like I said above, mine was found at:

C:\Program Files (x86)\Google\Chrome\Application

Click save and exit out of there. Then make sure you reboot your computer.

Hope this helps!

Here is a simple php script for login and a page that can only be accessed by logged in users.

login.php

    if(isset($_SESSION['login'])) {
      header('LOCATION:index.php'); die();
    }

        if($username === 'admin' && $password === 'password'){
          $_SESSION['login'] = true; header('LOCATION:admin.php'); die();
        } {

      </div>
      <button type="submit" name="submit" class="btn btn-default">Login</button>
    </form>
  </div>
</body>
</html>

admin.php ( only logged in users can access it )

<?php
    session_start();
    if(!isset($_SESSION['login'])) {
        header('LOCATION:login.php'); die();
    }
?>

    <head>
        <title>Admin Page</title>
    </head>
    <body>
        This is admin page view able only by logged in users.
    </body> 
</html>

If selection is not important, it is better to use an ItemsControl wrapped in a ScrollViewer. This combination is more light-weight than the Listbox (which actually is derived from ItemsControl already) and using it would eliminate the need to use a cheap hack to override behavior that is already absent from the ItemsControl.

In cases where the selection behavior IS actually important, then this obviously will not work. However, if you want to change the color of the Selected Item Background in such a way that it is not visible to the user, then that would only serve to confuse them. In cases where your intention is to change some other characteristic to indicate that the item is selected, then some of the other answers to this question may still be more relevant.

Here is a skeleton of how the markup should look:

    <ScrollViewer>
        <ItemsControl>
            <ItemsControl.ItemTemplate>
                <DataTemplate>
                    ...
                </DataTemplate>
            </ItemsControl.ItemTemplate>
        </ItemsControl>
    </ScrollViewer>

Here's yet another, but I feel more straightforward and intuitive (or at least natural if you're used to Promises), approach. Basically, you create an Observable using Observable.create() to wrap one and two as a single Observable. This is very similar to how Promise.all() may work.

var first = someObservable.take(1);
var second = Observable.create((observer) => {
  return first.subscribe(
    function onNext(value) {
      /* do something with value like: */
      // observer.next(value);
    },
    function onError(error) {
      observer.error(error);
    },
    function onComplete() {
      someOtherObservable.take(1).subscribe(
        function onNext(value) {
          observer.next(value);
        },
        function onError(error) {
          observer.error(error);
        },
        function onComplete() {
          observer.complete();
        }
      );
    }
  );
});

So, what's going on here? First, we create a new Observable. The function passed to Observable.create(), aptly named onSubscription, is passed the observer (built from the parameters you pass to subscribe()), which is similar to resolve and reject combined into a single object when creating a new Promise. This is how we make the magic work.

In onSubscription, we subscribe to the first Observable (in the example above, this was called one). How we handle next and error is up to you, but the default provided in my sample should be appropriate generally speaking. However, when we receive the complete event, which means one is now done, we can subscribe to the next Observable; thereby firing the second Observable after the first one is complete.

The example observer provided for the second Observable is fairly simple. Basically, second now acts like what you would expect two to act like in the OP. More specifically, second will emit the first and only the first value emitted by someOtherObservable (because of take(1)) and then complete, assuming there is no error.

Example

Here is a full, working example you can copy/paste if you want to see my example working in real life:

var someObservable = Observable.from([1, 2, 3, 4, 5]);
var someOtherObservable = Observable.from([6, 7, 8, 9]);

var first = someObservable.take(1);
var second = Observable.create((observer) => {
  return first.subscribe(
    function onNext(value) {
      /* do something with value like: */
      observer.next(value);
    },
    function onError(error) {
      observer.error(error);
    },
    function onComplete() {
      someOtherObservable.take(1).subscribe(
        function onNext(value) {
          observer.next(value);
        },
        function onError(error) {
          observer.error(error);
        },
        function onComplete() {
          observer.complete();
        }
      );
    }
  );
}).subscribe(
  function onNext(value) {
    console.log(value);
  },
  function onError(error) {
    console.error(error);
  },
  function onComplete() {
    console.log("Done!");
  }
);

If you watch the console, the above example will print:

1

6

Done!

Update for Swift 4:

let now = Date() // the current date/time
let oneDayFromNow = Calendar.current.date(byAdding: .day, value: 1, to: now) // Tomorrow with same time of day as now

All you need is two flags, one is "-r" for recursion and "--no-parent" (or -np) in order not to go in the '.' and ".." . Like this:

wget -r --no-parent http://example.com/configs/.vim/

That's it. It will download into the following local tree: ./example.com/configs/.vim . However if you do not want the first two directories, then use the additional flag --cut-dirs=2 as suggested in earlier replies:

wget -r --no-parent --cut-dirs=2 http://example.com/configs/.vim/

And it will download your file tree only into ./.vim/

In fact, I got the first line from this answer precisely from the wget manual, they have a very clean example towards the end of section 4.3.

From Interface Builder:

Programmatically:

SWift 4

Using label extension

extension UILabel {

    func setLineSpacing(lineSpacing: CGFloat = 0.0, lineHeightMultiple: CGFloat = 0.0) {

        guard let labelText = self.text else { return }

        let paragraphStyle = NSMutableParagraphStyle()
        paragraphStyle.lineSpacing = lineSpacing
        paragraphStyle.lineHeightMultiple = lineHeightMultiple

        let attributedString:NSMutableAttributedString
        if let labelattributedText = self.attributedText {
            attributedString = NSMutableAttributedString(attributedString: labelattributedText)
        } else {
            attributedString = NSMutableAttributedString(string: labelText)
        }

        // Line spacing attribute
        attributedString.addAttribute(NSAttributedStringKey.paragraphStyle, value:paragraphStyle, range:NSMakeRange(0, attributedString.length))

        self.attributedText = attributedString
    }
}

Now call extension function

let label = UILabel()
let stringValue = "How to\ncontrol\nthe\nline spacing\nin UILabel"

// Pass value for any one argument - lineSpacing or lineHeightMultiple
label.setLineSpacing(lineSpacing: 2.0) .  // try values 1.0 to 5.0

// or try lineHeightMultiple
//label.setLineSpacing(lineHeightMultiple = 2.0) // try values 0.5 to 2.0

Or using label instance (Just copy & execute this code to see result)

let label = UILabel()
let stringValue = "Set\nUILabel\nline\nspacing"
let attrString = NSMutableAttributedString(string: stringValue)
var style = NSMutableParagraphStyle()
style.lineSpacing = 24 // change line spacing between paragraph like 36 or 48
style.minimumLineHeight = 20 // change line spacing between each line like 30 or 40

// Line spacing attribute
attrString.addAttribute(NSAttributedStringKey.paragraphStyle, value: style, range: NSRange(location: 0, length: stringValue.characters.count))

// Character spacing attribute
attrString.addAttribute(NSAttributedStringKey.kern, value: 2, range: NSMakeRange(0, attrString.length))

label.attributedText = attrString

Swift 3

let label = UILabel()
let stringValue = "Set\nUILabel\nline\nspacing"
let attrString = NSMutableAttributedString(string: stringValue)
var style = NSMutableParagraphStyle()
style.lineSpacing = 24 // change line spacing between paragraph like 36 or 48
style.minimumLineHeight = 20 // change line spacing between each line like 30 or 40
attrString.addAttribute(NSParagraphStyleAttributeName, value: style, range: NSRange(location: 0, length: stringValue.characters.count))
label.attributedText = attrString

These work

SET GLOBAL LOG_SLOW_TIME = 1;
SET GLOBAL LOG_QUERIES_NOT_USING_INDEXES = ON;

Broken on my setup 5.1.42

SET GLOBAL LOG_SLOW_QUERIES = ON;
SET GLOBAL SLOW_QUERY_LOG = ON;
set @@global.log_slow_queries=1;

http://bugs.mysql.com/bug.php?id=32565

Looks like the best way to do this is set log_slow_time very high thus "turning off" the slow query log. Lower log_slow_time to enable it. Use the same trick (set to OFF) for log_queries_not_using_indexes.

There are 3 different things we are using here :

1. JPA : Java persistence api which provide specification for persisting, reading, managing data from your java object to relations in database.
2. Hibernate: There are various provider which implement jpa. Hibernate is one of them. So we have other provider as well. But if using jpa with spring it allows you to switch to different providers in future.
3. Spring Data JPA : This is another layer on top of jpa which spring provide to make your life easy.

So lets understand how spring data jpa and spring + hibernate works-

Spring Data JPA:

Let's say you are using spring + hibernate for your application. Now you need to have dao interface and implementation where you will be writing crud operation using SessionFactory of hibernate. Let say you are writing dao class for Employee class, tomorrow in your application you might need to write similiar crud operation for any other entity. So there is lot of boilerplate code we can see here.

Now Spring data jpa allow us to define dao interfaces by extending its repositories(crudrepository, jparepository) so it provide you dao implementation at runtime. You don't need to write dao implementation anymore.Thats how spring data jpa makes your life easy.

I had a serious issue with pseudo random number generator in my recent application: I repeatidly called my C program via a pyhton script and I was using as seed the following code:

srand(time(NULL))

However, since:

• rand will generate the same pseudo random sequence give the same seed in srand (see man srand);
• As already stated, time function changes only second from second: if your application is run multiple times within the same second, time will return the same value each time.

My program generated the same sequence of numbers. You can do 3 things to solve this problem:

1. mix time output with some other information changing on runs (in my application, the output name):

   srand(time(NULL) | getHashOfString(outputName))
   

   I used djb2 as my hash function.

2. Increase time resolution. On my platform, clock_gettime was available, so I use it:

   #include<time.h>
   struct timespec nanos;
   clock_gettime(CLOCK_MONOTONIC, &nanos)
   srand(nanos.tv_nsec);
   

3. Use both methods together:

   #include<time.h>
   struct timespec nanos;
   clock_gettime(CLOCK_MONOTONIC, &nanos)
   srand(nanos.tv_nsec | getHashOfString(outputName));
   

Option 3 ensures you (as far as i know) the best seed randomity, but it may create a difference only on very fast application. In my opinion option 2 is a safe bet.

    $scope.toggleRightDelayed = function(){
        var myInterval = $interval(function(){
            $scope.toggleRight();
        },1000,1)
        .then(function(){
            $interval.cancel(myInterval);
        });
    };

Yes, I understood your problem. If is difficult to identify cell has Numeric or Data value.

If you want data in format that shows in Excel, you just need to format cell using DataFormatter class.

DataFormatter dataFormatter = new DataFormatter();
String cellStringValue = dataFormatter.formatCellValue(row.getCell(0));
System.out.println ("Is shows data as show in Excel file" + cellStringValue);  // Here it automcatically format data based on that cell format.
// No need for extra efforts 

This may be obvious, but you can inline the array like so:

package main

import (
    "fmt"
)

func main() {
    for _, element := range [3]string{"a", "b", "c"} {
        fmt.Print(element)
    }
}

outputs:

abc

I did it even simpler. Problem: A CSS file had url links to img folder. Gets 404.

I looked at url, http://tomcatfolder:port/img/blablah.png, which does not exist. But, that is really pointing to the ROOT app in Tomcat.

So I just copied the img folder from my webapp into that ROOT app. Works!

Not recommended for production, of course, but this is for an internal tool dev app.

Your variable size is declared as: float size;

You can't use a floating point variable as the size of an array - it needs to be an integer value.

You could cast it to convert to an integer:

float *temp = new float[(int)size];

Your other problem is likely because you're writing outside of the bounds of the array:

   float *temp = new float[size];

    //Getting input from the user
    for (int x = 1; x <= size; x++){
        cout << "Enter temperature " << x << ": ";

        // cin >> temp[x];
        // This should be:
        cin >> temp[x - 1];
    }

Arrays are zero based in C++, so this is going to write beyond the end and never write the first element in your original code.

If you're trying to run a program using a scripting language, you may need to include the full path of the scripting language and the file to execute. For example:

exec('/usr/local/bin/node /usr/local/lib/node_modules/uglifycss/uglifycss in.css > out.css');

If save to a JSON file, the best and easiest way of doing this is:

import json
with open("file.json", "wb") as f:
    f.write(json.dumps(dict).encode("utf-8"))

Even without importing swing, you can get the call in one, all be it long, string. Otherwise just use the swing import and simple call:

JOptionPane.showMessageDialog(null, "Thank you for using Java", "Yay, java", JOptionPane.PLAIN_MESSAGE);

Easy enough.

I was looking for the same thing for a quick operation and found this question. I needed both 32-bit and 64-bit versions.

This is an older version but the links are from the Microsoft servers, it should be safe. The link for 32-bit version is also in a previous answer but the version number i get on the install is different, maybe the same link is updated with a newer version since 2013.

e.which doesn't work in IE try e.keyCode, also you probably want to use keydown() instead of keypress() if you are targeting IE.

If you do not want to use Docker Compose, I can recommend portainer. It has a recreate function that lets you recreate a container while pulling the latest image.

I also designed a "php session value setter" solution by myself (similar to Luke Dennis' solution. No big deal here), but after setting my session value, my needs were "jumping onto another .php file". Ok, I did it, inside my jquery code... But something didn't quite work...

My problem was kind of easy:

-After you "$.post" your values onto the small .php file, you should wait for some "success/failure" return value, and ONLY AFTER READING THIS SUCCESS VALUE, perform the jump. If you just immediately jump onto the next big .php file, your session value might have not become set onto the php sessions runtime engine, and will you probably read "empty" when doing $_SESSION["my_var"]; from the destination .php file.

In my case, to correct that situation, I changed my jQuery $.post code this way:

$.post('set_session_value.php', { key: 'keyname', value: 'myvalue'}, function(ret){
    if(ret==0){
        window.alert("success!");
        location.replace("next_page.php");
    }
    else{
        window.alert("error!");
    }
});

Of course, your "set_session_value.php" file, should return 'echo "0"; ' or 'echo "1"; ' (or whatever success values you might need).

Greetings.

Floated elements do not occupy the space inside of the parent element, As the name suggests they float! Thus if a height is explicitly not provided to an element having its child elements floated, then the parent element will appear to shrink & appear to not accepting dimensions of the child element, also if its given overflow:hidden; its children may not appear on screen. There are multiple ways to deal with this problem:

1. Insert another element below the floated element with clear:both; property, or use clear:both; on :after of the floated element.

2. Use display:inline-block; or flex-box instead of float.

You can use usort function to create own sorting rules

LCM is both associative and commutative.

LCM(a,b,c)=LCM(LCM(a,b),c)=LCM(a,LCM(b,c))

here is sample code in C:

int main()
{
  int a[20],i,n,result=1;  // assumption: count can't exceed 20
  printf("Enter number of numbers to calculate LCM(less than 20):");
  scanf("%d",&n);
  printf("Enter %d  numbers to calculate their LCM :",n);
  for(i=0;i<n;i++)
    scanf("%d",&a[i]);
 for(i=0;i<n;i++)
   result=lcm(result,a[i]);
 printf("LCM of given numbers = %d\n",result);
 return 0;
}

int lcm(int a,int b)
{
  int gcd=gcd_two_numbers(a,b);
  return (a*b)/gcd;
}

int gcd_two_numbers(int a,int b)
{
   int temp;
   if(a>b)
   {
     temp=a;
     a=b;
     b=temp;
   }
  if(b%a==0)
    return a;
  else
    return gcd_two_numbers(b%a,a);
}

Make sure all your own referenced dlls have "Copy Local" set to True in the Properties window, unless they are in the GAC. There is no need to do this with framework dlls.

The best approach in Swift above 1.2 is a one-line singleton, as -

class Shared: NSObject {

    static let sharedInstance = Shared()

    private override init() { }
}

To know more detail about this approach you can visit this link.

You can change the collation of your text field to UTF8_general_ci and the problem will be solved.

Notice, this cannot be done in Django.

It's explained well here.

If the input variables are combined linearly, as in an MLP [multilayer perceptron], then it is rarely strictly necessary to standardize the inputs, at least in theory. The reason is that any rescaling of an input vector can be effectively undone by changing the corresponding weights and biases, leaving you with the exact same outputs as you had before. However, there are a variety of practical reasons why standardizing the inputs can make training faster and reduce the chances of getting stuck in local optima. Also, weight decay and Bayesian estimation can be done more conveniently with standardized inputs.

You can use the following if you want to specify tricky formats:

df['date_col'] =  pd.to_datetime(df['date_col'], format='%d/%m/%Y')

More details on format here:

• Python 2 https://docs.python.org/2/library/datetime.html#strftime-strptime-behavior
• Python 3 https://docs.python.org/3.7/library/datetime.html#strftime-strptime-behavior

It forces the browser to use hardware acceleration to access the device’s graphical processing unit (GPU) to make pixels fly. Web applications, on the other hand, run in the context of the browser, which lets the software do most (if not all) of the rendering, resulting in less horsepower for transitions. But the Web has been catching up, and most browser vendors now provide graphical hardware acceleration by means of particular CSS rules.

Using -webkit-transform: translate3d(0,0,0); will kick the GPU into action for the CSS transitions, making them smoother (higher FPS).

Note: translate3d(0,0,0) does nothing in terms of what you see. It moves the object by 0px in x,y and z axis. It's only a technique to force the hardware acceleration.

Good read here: http://www.smashingmagazine.com/2012/06/21/play-with-hardware-accelerated-css/

Make sure to target x86 on your project in Visual Studio. This should fix your trouble.

For testing purposes I use the following:

//return assoc array when called from outside the class it will only contain public properties and values 
var_dump(get_object_vars($obj)); 

Along the lines of ggovan's answer, I do this as follows:

/**
 * Provides various high-order functions.
 */
public final class F {
    /**
     * When the returned {@code Function} is passed as an argument to
     * {@link Stream#flatMap}, the result is a stream of instances of
     * {@code cls}.
     */
    public static <E> Function<Object, Stream<E>> instancesOf(Class<E> cls) {
        return o -> cls.isInstance(o)
                ? Stream.of(cls.cast(o))
                : Stream.empty();
    }
}

Using this helper function:

Stream.of(objects).flatMap(F.instancesOf(Client.class))
        .map(Client::getId)
        .forEach(System.out::println);

When I have a similar issue when reading text files i use...

f = open('file','rt', errors='ignore')

Same for end of week (in style of @Compile This's answer):

    public static DateTime EndOfWeek(this DateTime dt)
    {
        int diff = 7 - (int)dt.DayOfWeek;

        diff = diff == 7 ? 0 : diff;

        DateTime eow = dt.AddDays(diff).Date;

        return new DateTime(eow.Year, eow.Month, eow.Day, 23, 59, 59, 999) { };
    }

If you know that your dataframe has only one column, you can use: names(trSamp) <- "newname2"

I don't think it guarantees the order of calling logger.log(res);

Actually, it does. That statement is executed before the resolve call.

Any suggestions?

Lots. The most important is your use of the create-promise-manually antipattern - just do only

promiseWhile(…, function() {
    return db.getUser(email)
             .then(function(res) { 
                 logger.log(res); 
                 count++;
             });
})…

Second, that while function could be simplified a lot:

var promiseWhile = Promise.method(function(condition, action) {
    if (!condition()) return;
    return action().then(promiseWhile.bind(null, condition, action));
});

Third, I would not use a while loop (with a closure variable) but a for loop:

var promiseFor = Promise.method(function(condition, action, value) {
    if (!condition(value)) return value;
    return action(value).then(promiseFor.bind(null, condition, action));
});

promiseFor(function(count) {
    return count < 10;
}, function(count) {
    return db.getUser(email)
             .then(function(res) { 
                 logger.log(res); 
                 return ++count;
             });
}, 0).then(console.log.bind(console, 'all done'));

Creating colnames with iterating

df = pd.DataFrame(columns=['colname_' + str(i) for i in range(5)])
print(df)

# Empty DataFrame
# Columns: [colname_0, colname_1, colname_2, colname_3, colname_4]
# Index: []

to_html() operations

print(df.to_html())

# <table border="1" class="dataframe">
#   <thead>
#     <tr style="text-align: right;">
#       <th></th>
#       <th>colname_0</th>
#       <th>colname_1</th>
#       <th>colname_2</th>
#       <th>colname_3</th>
#       <th>colname_4</th>
#     </tr>
#   </thead>
#   <tbody>
#   </tbody>
# </table>

this seems working

print(type(df.to_html()))
# <class 'str'>

The problem is caused by

when you create df like this

df = pd.DataFrame(columns=COLUMN_NAMES)

it has 0 rows × n columns, you need to create at least one row index by

df = pd.DataFrame(columns=COLUMN_NAMES, index=[0])

now it has 1 rows × n columns. You are be able to add data. Otherwise its df that only consist colnames object(like a string list).

This could be due to the current user having an undefined ExecutionPolicy.

You could try the following:

Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted

To get the lines that contain the texts 8768, 9875 or 2353, use:

^.*(8768|9875|2353).*$

What it means:

^                      from the beginning of the line
.*                     get any character except \n (0 or more times)
(8768|9875|2353)       if the line contains the string '8768' OR '9875' OR '2353'
.*                     and get any character except \n (0 or more times)
$                      until the end of the line

If you do want the literal * char, you'd have to escape it:

^.*(\*8768|\*9875|\*2353).*$

1. edit your .bash_profile file

   vim .bash_profile

2. commnet

   export TERM=xterm-basic

   to your .bash_profile

4. finally

   run:

   source .bash_profile

If you are using the tidyverse, you can use

as_data_frame(table(myvector))

to get a tibble (i.e. a data frame with some minor variations from the base class)

Well, this may not be the most elegant solution (semantically), but in some cases it'll work without any drawbacks: Instead of padding, use a transparent border on the parent element. The absolute positioned child elements will honor the border and it'll be rendered exactly the same (except you're using the border of the parent element for styling).

// or considering your array structure:

$array = array(
  'string1' => array('a' => '', 'b' => '', 'c' => ''),
  'string2' => array('a' => '', 'b' => '', 'c' => ''),
  'string3' => array('a' => '', 'b' => '', 'c' => ''),
);

// you could just

function findIndexOfKey($key_to_index,$array){
  return array_search($key_to_index,array_keys($array));
}

// executed

print "\r\n//-- Method 1 --//\r\n";
print '#index of: string1 = '.findIndexofKey('string1',$array)."\r\n";
print '#index of: string2 = '.findIndexofKey('string2',$array)."\r\n";
print '#index of: string3 = '.findIndexofKey('string3',$array)."\r\n";

// alternatively

print "\r\n//-- Method 2 --//\r\n";
print '#index of: string1 = '.array_search('string1',array_keys($array))."\r\n";
print '#index of: string2 = '.array_search('string2',array_keys($array))."\r\n";
print '#index of: string3 = '.array_search('string3',array_keys($array))."\r\n";

// recursersively

print "\r\n//-- Method 3 --//\r\n";
foreach(array_keys($array) as $key => $value){
  print '#index of: '.$value.' = '.$key."\r\n";
}

// outputs

//-- Method 1 --//
#index of: string1 = 0
#index of: string2 = 1
#index of: string3 = 2

//-- Method 2 --//
#index of: string1 = 0
#index of: string2 = 1
#index of: string3 = 2

//-- Method 3 --//
#index of: string1 = 0
#index of: string2 = 1
#index of: string3 = 2

If you want to set the background using a hex color you could do this:

var bc = new BrushConverter();

myTextBox.Background = (Brush)bc.ConvertFrom("#FFXXXXXX");

Or you could set up a SolidColorBrush resource in XAML, and then use findResource in the code-behind:

<SolidColorBrush x:Key="BrushFFXXXXXX">#FF8D8A8A</SolidColorBrush>
myTextBox.Background = (Brush)Application.Current.MainWindow.FindResource("BrushFFXXXXXX");

The code you listed kind of looks like a Lehmer RNG. If this is the case, then 2147483647 is the largest 32-bit signed integer, 2147483647 is the largest 32-bit prime, and 48271 is a full-period multiplier that is used to generate the numbers.

If this is true, you could modify RandomNumberGenerator to take in an extra parameter seed, and then set this.seed to seed; but you'd have to be careful to make sure the seed would result in a good distribution of random numbers (Lehmer can be weird like that) -- but most seeds will be fine.

Here is another way that I came up with: Let's say you want to get a float between 5.5 and 7, with 3 decimals.

float myFloat;
int myInt;
System.Random rnd = new System.Random();

void GenerateFloat()
{
myInt = rnd.Next(1, 2000);
myFloat = (myInt / 1000) + 5.5f;
}

That way you will always get a bigger number than 5.5 and a smaller number than 7.

int is a primitive type that represent an integer. whereas Integer is an Object that wraps int. The Integer object gives you more functionality, such as converting to hex, string, etc.

You can also use OOP concepts with Integer. For example, you can use Integer for generics (i.e. Collection<Integer>).

from sklearn import metrics
import bumpy as np
print(no.sqrt(metrics.mean_squared_error(actual,predicted)))

Your assumptions don't seem to be right. After a clear(), the newly added data start from index 0.

Method1: ADD_MONTHS

ADD_MONTHS(SYSDATE, -6)

Method 2: Interval

SYSDATE - interval '6' month

Note: if you want to do the operations from start of the current month always, TRUNC(SYSDATE,'MONTH') would give that. And it expects a Date datatype as input.

I have found the simplest (cheap and cheerful) solution is simply add an empty span with ng-show = "someFunctionThatAlwaysReturnsZeroOrNothing()" to the end of the last element rendered. This function will be run when to check if the span element should be displayed. Execute any other code in this function.

I realize this is not the most elegant way to do things, however, it works for me...

I had a similar situation, though slightly reversed where I needed to remove a loading indicator when an animation began, on mobile devices angular was initializing much faster than the animation to be displayed, and using an ng-cloak was insufficient as the loading indicator was removed well before any real data was displayed. In this case I just added the my return 0 function to the first rendered element, and in that function flipped the var that hides the loading indicator. (of course I added an ng-hide to the loading indicator triggered by this function.

Assuming that your List is a list of strings make data an ArrayList<String> and use intent.putStringArrayListExtra("data", data)

Here is a skeleton of the code you need:

1. Declare List

   private List<String> test;
   

2. Init List at appropriate place

   test = new ArrayList<String>();
   

   and add data as appropriate to test.

3. Pass to intent as follows:

   Intent intent = getIntent();  
   intent.putStringArrayListExtra("test", (ArrayList<String>) test);
   

4. Retrieve data as follows:

   ArrayList<String> test = getIntent().getStringArrayListExtra("test");
   

Hope that helps.

I got the same error. I uninstalled the app on my virtual device and rerun the command: 'react-native run-android'.

To display a value nicely, you can use the pprint module. The easiest way to dump all variables with it is to do

from pprint import pprint

pprint(globals())
pprint(locals())

If you are running in CGI, a useful debugging feature is the cgitb module, which displays the value of local variables as part of the traceback.

This isn't quite what you're looking for, but I've found it useful in similar circumstances.

I recently added the following to my $HOME/.bashrc (something similar should be possible with shells other than bash):

if [ -f $HOME/.add-screen-to-history ] ; then
    history -s 'screen -dr'
fi

I keep a screen session running on one particular machine, and I've had problems with ssh connections to that machine being dropped, requiring me to re-run screen -dr every time I reconnect.

With that addition, and after creating that (empty) file in my home directory, I automatically have the screen -dr command in my history when my shell starts. After reconnecting, I can just type Control-P Enter and I'm back in my screen session -- or I can ignore it. It's flexible, but not quite automatic, and in your case it's easier than typing tmux list-sessions.

You might want to make the history -s command unconditional.

This does require updating your $HOME/.bashrc on each of the target systems, which might or might not make it unsuitable for your purposes.

A bit more along the same lines

attrs <- {}

attrs.a <- 1

f <- function(d) {
    attrs.a <- d
}

f(20)
print(attrs.a)

will print "1"

attrs <- {}

attrs.a <- 1

f <- function(d) {
   attrs.a <<- d
}

f(20)
print(attrs.a)

Will print "20"

on windows open a cmd.exe window with administrator permissions and use netstat -a -b -o you will get the id of the proccess that holds your port and be able to kill it using task manager.

You can try:

top -bn1 | grep "Cpu(s)" | \
           sed "s/.*, *\([0-9.]*\)%* id.*/\1/" | \
           awk '{print 100 - $1"%"}'

Everything everyone is saying is correct so,

int[] aArray = {1,2,3};
List<int> list = aArray.OfType<int> ().ToList();

would turn aArray into a list, list. However the biggest thing that is missing from a lot of comments is that you need to have these 2 using statements at the top of your class

using System.Collections.Generic;
using System.Linq;

I hope this helps!

update: Xcode 11.5 • Swift 5.2

if let documentsPath = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first?.path {
    print(documentsPath)   // "var/folder/.../documents\n" copy the full path
}

Go to your Finder press command-shift-g (or Go > Go to Folder... under the menu bar) and paste that full path "var/folder/.../documents" there and press go.

This is certainly something that has a lot of traps. I was working with Paolo Bergantino's answer, and realising that even that has some limitations. I found working with string representations of dates a good place to quickly find some of the main problems. Start with an input string like this: '12-2-2019 5:1:48.670'

and set up Paolo's function like this:

function count(re, str) {
    if (typeof re !== "string") {
        return 0;
    }
    re = (re === '.') ? ('\\' + re) : re;
    var cre = new RegExp(re, 'g');
    return ((str || '').match(cre) || []).length;
}

I wanted the regular expression to be passed in, so that the function is more reusable, secondly, I wanted the parameter to be a string, so that the client doesn't have to make the regex, but simply match on the string, like a standard string utility class method.

Now, here you can see that I'm dealing with issues with the input. With the following:

if (typeof re !== "string") {
    return 0;
}

I am ensuring that the input isn't anything like the literal 0, false, undefined, or null, none of which are strings. Since these literals are not in the input string, there should be no matches, but it should match '0', which is a string.

With the following:

re = (re === '.') ? ('\\' + re) : re;

I am dealing with the fact that the RegExp constructor will (I think, wrongly) interpret the string '.' as the all character matcher \.\

Finally, because I am using the RegExp constructor, I need to give it the global 'g' flag so that it counts all matches, not just the first one, similar to the suggestions in other posts.

I realise that this is an extremely late answer, but it might be helpful to someone stumbling along here. BTW here's the TypeScript version:

function count(re: string, str: string): number {
    if (typeof re !== 'string') {
        return 0;
    }
    re = (re === '.') ? ('\\' + re) : re;
    const cre = new RegExp(re, 'g');    
    return ((str || '').match(cre) || []).length;
}

Finally, i solved the problem. I placed the `nitm.sql` file in `bin` file of the `mysql` folder and used the following syntax.

C:\wamp\bin\mysql\mysql5.0.51b\bin>mysql -u root nitm < nitm.sql

And this worked.

Besides authentication flow shown in the other answer, role-based authorization can be supported in the REST endpoints.

Create an enumeration and define the roles according to your needs:

public enum Role {
    ROLE_1,
    ROLE_2,
    ROLE_3
}

Change the @Secured name binding annotation created before to support roles:

@NameBinding
@Retention(RUNTIME)
@Target({TYPE, METHOD})
public @interface Secured {
    Role[] value() default {};
}

And then annotate the resource classes and methods with @Secured to perform the authorization. The method annotations will override the class annotations:

@Path("/example")
@Secured({Role.ROLE_1})
public class ExampleResource {

    @GET
    @Path("{id}")
    @Produces(MediaType.APPLICATION_JSON)
    public Response myMethod(@PathParam("id") Long id) {
        // This method is not annotated with @Secured
        // But it's declared within a class annotated with @Secured({Role.ROLE_1})
        // So it only can be executed by the users who have the ROLE_1 role
        ...
    }

    @DELETE
    @Path("{id}")    
    @Produces(MediaType.APPLICATION_JSON)
    @Secured({Role.ROLE_1, Role.ROLE_2})
    public Response myOtherMethod(@PathParam("id") Long id) {
        // This method is annotated with @Secured({Role.ROLE_1, Role.ROLE_2})
        // The method annotation overrides the class annotation
        // So it only can be executed by the users who have the ROLE_1 or ROLE_2 roles
        ...
    }
}

Create a filter with the AUTHORIZATION priority, which is executed after the AUTHENTICATION priority filter defined previously.

The ResourceInfo can be used to get the resource Method and resource Class that will handle the request and then extract the @Secured annotations from them:

@Secured
@Provider
@Priority(Priorities.AUTHORIZATION)
public class AuthorizationFilter implements ContainerRequestFilter {

    @Context
    private ResourceInfo resourceInfo;

    @Override
    public void filter(ContainerRequestContext requestContext) throws IOException {

        // Get the resource class which matches with the requested URL
        // Extract the roles declared by it
        Class<?> resourceClass = resourceInfo.getResourceClass();
        List<Role> classRoles = extractRoles(resourceClass);

        // Get the resource method which matches with the requested URL
        // Extract the roles declared by it
        Method resourceMethod = resourceInfo.getResourceMethod();
        List<Role> methodRoles = extractRoles(resourceMethod);

        try {

            // Check if the user is allowed to execute the method
            // The method annotations override the class annotations
            if (methodRoles.isEmpty()) {
                checkPermissions(classRoles);
            } else {
                checkPermissions(methodRoles);
            }

        } catch (Exception e) {
            requestContext.abortWith(
                Response.status(Response.Status.FORBIDDEN).build());
        }
    }

    // Extract the roles from the annotated element
    private List<Role> extractRoles(AnnotatedElement annotatedElement) {
        if (annotatedElement == null) {
            return new ArrayList<Role>();
        } else {
            Secured secured = annotatedElement.getAnnotation(Secured.class);
            if (secured == null) {
                return new ArrayList<Role>();
            } else {
                Role[] allowedRoles = secured.value();
                return Arrays.asList(allowedRoles);
            }
        }
    }

    private void checkPermissions(List<Role> allowedRoles) throws Exception {
        // Check if the user contains one of the allowed roles
        // Throw an Exception if the user has not permission to execute the method
    }
}

If the user has no permission to execute the operation, the request is aborted with a 403 (Forbidden).

To know the user who is performing the request, see my previous answer. You can get it from the SecurityContext (which should be already set in the ContainerRequestContext) or inject it using CDI, depending on the approach you go for.

If a @Secured annotation has no roles declared, you can assume all authenticated users can access that endpoint, disregarding the roles the users have.

Supporting role-based authorization with JSR-250 annotations

Alternatively to defining the roles in the @Secured annotation as shown above, you could consider JSR-250 annotations such as @RolesAllowed, @PermitAll and @DenyAll.

JAX-RS doesn't support such annotations out-of-the-box, but it could be achieved with a filter. Here are a few considerations to keep in mind if you want to support all of them:

• @DenyAll on the method takes precedence over @RolesAllowed and @PermitAll on the class.
• @RolesAllowed on the method takes precedence over @PermitAll on the class.
• @PermitAll on the method takes precedence over @RolesAllowed on the class.
• @DenyAll can't be attached to classes.
• @RolesAllowed on the class takes precedence over @PermitAll on the class.

So an authorization filter that checks JSR-250 annotations could be like:

@Provider
@Priority(Priorities.AUTHORIZATION)
public class AuthorizationFilter implements ContainerRequestFilter {

    @Context
    private ResourceInfo resourceInfo;

    @Override
    public void filter(ContainerRequestContext requestContext) throws IOException {

        Method method = resourceInfo.getResourceMethod();

        // @DenyAll on the method takes precedence over @RolesAllowed and @PermitAll
        if (method.isAnnotationPresent(DenyAll.class)) {
            refuseRequest();
        }

        // @RolesAllowed on the method takes precedence over @PermitAll
        RolesAllowed rolesAllowed = method.getAnnotation(RolesAllowed.class);
        if (rolesAllowed != null) {
            performAuthorization(rolesAllowed.value(), requestContext);
            return;
        }

        // @PermitAll on the method takes precedence over @RolesAllowed on the class
        if (method.isAnnotationPresent(PermitAll.class)) {
            // Do nothing
            return;
        }

        // @DenyAll can't be attached to classes

        // @RolesAllowed on the class takes precedence over @PermitAll on the class
        rolesAllowed = 
            resourceInfo.getResourceClass().getAnnotation(RolesAllowed.class);
        if (rolesAllowed != null) {
            performAuthorization(rolesAllowed.value(), requestContext);
        }

        // @PermitAll on the class
        if (resourceInfo.getResourceClass().isAnnotationPresent(PermitAll.class)) {
            // Do nothing
            return;
        }

        // Authentication is required for non-annotated methods
        if (!isAuthenticated(requestContext)) {
            refuseRequest();
        }
    }

    /**
     * Perform authorization based on roles.
     *
     * @param rolesAllowed
     * @param requestContext
     */
    private void performAuthorization(String[] rolesAllowed, 
                                      ContainerRequestContext requestContext) {

        if (rolesAllowed.length > 0 && !isAuthenticated(requestContext)) {
            refuseRequest();
        }

        for (final String role : rolesAllowed) {
            if (requestContext.getSecurityContext().isUserInRole(role)) {
                return;
            }
        }

        refuseRequest();
    }

    /**
     * Check if the user is authenticated.
     *
     * @param requestContext
     * @return
     */
    private boolean isAuthenticated(final ContainerRequestContext requestContext) {
        // Return true if the user is authenticated or false otherwise
        // An implementation could be like:
        // return requestContext.getSecurityContext().getUserPrincipal() != null;
    }

    /**
     * Refuse the request.
     */
    private void refuseRequest() {
        throw new AccessDeniedException(
            "You don't have permissions to perform this action.");
    }
}

^{Note: The above implementation is based on the Jersey RolesAllowedDynamicFeature. If you use Jersey, you don't need to write your own filter, just use the existing implementation.}

If you are on mac, Use rvm to install your specific version of ruby. See https://owanateamachree.medium.com/how-to-install-ruby-using-ruby-version-manager-rvm-on-macos-mojave-ab53f6d8d4ec

Make sure you follow all the steps. This worked for me.

instead of getting Notepad++, You can simply Open the file with Wordpad and then Save As - Plain Text document

redirect_to :controller => "controller_name", :action => "action_name", :id => x.id

If you are using Spring Framework with application.yml and having trouble to make the test find the SQL file on the INIT property, you can use the classpath: notation.

For example, if you have a init.sql SQL file on the src/test/resources, just use:

url=jdbc:h2:~/test;INIT=RUNSCRIPT FROM 'classpath:init.sql';DB_CLOSE_DELAY=-1;

use maven dependency

<dependency> 
  <groupId>org.apache.commons</groupId>
  <artifactId>commons-io</artifactId> 
  <version>1.3.2</version> 
</dependency> 

or download commons-io.1.3.2.jar to your lib folder

It means that you wrote to some variables on the stack in an illegal way, most likely as the result of a Buffer overflow.

It should usually work using the method Dave described in his answer. (I can confirm seeing "TextFX Characters" in the Available tab in Plugin Manager.)

If it does not, you can try downloading the zip file from here and put its contents (it's one file called NppTextFX.dll) inside the plugins folder where Notepad++ is installed. I suggest doing this while Notepad++ itself is not running.

Bit late for reply but this should do the trick

Type myType = Type.GetType("AssemblyQualifiedName");

your assembly qualified name should be like this

"Boom.Bam.Class, Boom.Bam, Version=1.0.0.262, Culture=neutral, PublicKeyToken=e16dba1a3c4385bd"

Try:

To_Date (SESSION_START_DATE_TIME, 'MM/DD/YYYY hh24:mi') > 
To_Date ('12-Jan-2012 16:00', 'DD-MON-YYYY hh24:mi' )

when I use MVC5, and add the claim here.

public async Task<ClaimsIdentity> GenerateUserIdentityAsync(PATAUserManager manager)
    {
        // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
        var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
        // Add custom user claims here
        userIdentity.AddClaim(new Claim(ClaimTypes.Role, this.Role));

        return userIdentity;
    }

when I'm check the claim result in the SignInAsync function,i can't get the role value use anyway. But...

after this request finished, I can access Role in other action(anther request).

 var userWithClaims = (ClaimsPrincipal)User;
        Claim CRole = userWithClaims.Claims.First(c => c.Type == ClaimTypes.Role);

so, i think maybe asynchronous cause the IEnumerable updated behind the process.

I had this problem today and just looking the building configurations in Visual Studio wasn't helping because it showed Any CPU for both the project that wasn't building and the referenced project.

I then looked in the csproj of the referenced project and found this:

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|AnyCPU' ">
<DebugType>pdbonly</DebugType>
<Optimize>true</Optimize>
<OutputPath>bin\Release\</OutputPath>
<DefineConstants>TRACE</DefineConstants>
<ErrorReport>prompt</ErrorReport>
<WarningLevel>4</WarningLevel>
<PlatformTarget>x64</PlatformTarget>

Somehow this PlatformTarget got added in the middle of a config change and the IDE didn't seem to see it.

Removing this line from the referenced project solved my problem.

I found a bug in shermy's vanilla C# 3.5 .NET solution which otherwise works a charm. I have also incorporated Damian Leszczynski - Vash's SecureString idea here but you can use an ordinary string if you prefer.

THE BUG: If you press backspace during the password prompt and the current length of the password is 0 then an asterisk is incorrectly inserted in the password mask. To fix this bug modify the following method.

    public static string ReadPassword(char mask)
    {
        const int ENTER = 13, BACKSP = 8, CTRLBACKSP = 127;
        int[] FILTERED = { 0, 27, 9, 10 /*, 32 space, if you care */ }; // const


        SecureString securePass = new SecureString();

        char chr = (char)0;

        while ((chr = System.Console.ReadKey(true).KeyChar) != ENTER)
        {
            if (((chr == BACKSP) || (chr == CTRLBACKSP)) 
                && (securePass.Length > 0))
            {
                System.Console.Write("\b \b");
                securePass.RemoveAt(securePass.Length - 1);

            }
            // Don't append * when length is 0 and backspace is selected
            else if (((chr == BACKSP) || (chr == CTRLBACKSP)) && (securePass.Length == 0))
            {
            }

            // Don't append when a filtered char is detected
            else if (FILTERED.Count(x => chr == x) > 0)
            {
            }

            // Append and write * mask
            else
            {
                securePass.AppendChar(chr);
                System.Console.Write(mask);
            }
        }

        System.Console.WriteLine();
        IntPtr ptr = new IntPtr();
        ptr = Marshal.SecureStringToBSTR(securePass);
        string plainPass = Marshal.PtrToStringBSTR(ptr);
        Marshal.ZeroFreeBSTR(ptr);
        return plainPass;
    }

Possible repeated question from How to overcome the CORS issue in ReactJS

CORS works by adding new HTTP headers that allow servers to describe the set of origins that are permitted to read that information using a web browser. This must be configured in the server to allow cross domain.

You can temporary solve this issue by a chrome plugin called CORS.

This command works for me:

./mysql -u root -p

(PS: I'm working on mac through terminal)

The following example using the iris dataset works fine:

dat = melt(subset(iris, select = c("Sepal.Length","Sepal.Width", "Species")),
      id.vars = "Species")
ggplot(aes(x = 1:nrow(iris), y = value, color = variable), data = dat) +  
      geom_point() + geom_line()

table {
    border-collapse: collapse;
}

$('.class').find('tag').attr('src');

If you're actually building a real system, then yes, you'd typically just use the stuff in the standard library if what you need is available there. That said, don't think of this as a pointless exercise. It's good to understand how things work, and understanding linked lists is an important step towards understanding more complex data structures, many of which don't exist in the standard libraries.

There are some differences between the way you're creating a linked list and the way the Java collections API does it. The Collections API is trying to adhere to a more complicated interface. The Collections API linked list is also a doubly linked list, while you're building a singly linked list. What you're doing is more appropriate for a class assignment.

With your LinkedList class, an instance will always be a list of at least one element. With this kind of setup you'd use null for when you need an empty list.

Think of next as being "the rest of the list". In fact, many similar implementations use the name "tail" instead of "next".

Here's a diagram of a LinkedList containing 3 elements:

Note that it's a LinkedList object pointing to a word ("Hello") and a list of 2 elements. The list of 2 elements has a word ("Stack") and a list of 1 element. That list of 1 element has a word ("Overflow") and an empty list (null). So you can treat next as just another list that happens to be one element shorter.

You may want to add another constructor that just takes a String, and sets next to null. This would be for creating a 1-element list.

To append, you check if next is null. If it is, create a new one element list and set next to that.

next = new LinkedList(word);

If next isn't null, then append to next instead.

next.append(word);

This is the recursive approach, which is the least amount of code. You can turn that into an iterative solution which would be more efficient in Java^*, and wouldn't risk a stack overflow with very long lists, but I'm guessing that level of complexity isn't needed for your assignment.

^{* Some languages have tail call elimination, which is an optimization that lets the language implementation convert "tail calls" (a call to another function as the very last step before returning) into (effectively) a "goto". This makes such code completely avoid using the stack, which makes it safer (you can't overflow the stack if you don't use the stack) and typically more efficient. Scheme is probably the most well known example of a language with this feature.}

One thing I've not found through the answers is that there are two possible landscape orientations, and I wanted to let both be available! So android:screenOrientation="landscape" will lock your app only to one of the 2 possibilities, but if you want your app to be limited to both landscape orientations (for them whom is not clear, having device on portrait, one is rotating left and the other one rotating right) this is what is needed:

android:screenOrientation="sensorLandscape"

To show both string.Split and Regex usage:

string input = "abc][rfd][5][,][.";
string[] parts1 = input.Split(new string[] { "][" }, StringSplitOptions.None);
string[] parts2 = Regex.Split(input, @"\]\[");

Update: As Roko C.Bulijan pointed out.. you need to use .insertAfter to insert it after the selected div. Also see updated code if you want it appended to the end instead of beginning when cloned multiple times. DEMO

Code:

   var cloneCount = 1;;
   $("button").click(function(){
      $('#id')
          .clone()
          .attr('id', 'id'+ cloneCount++)
          .insertAfter('[id^=id]:last') 
           //            ^-- Use '#id' if you want to insert the cloned 
           //                element in the beginning
          .text('Cloned ' + (cloneCount-1)); //<--For DEMO
   }); 

Try,

$("#id").clone().attr('id', 'id1').after("#id");

If you want a automatic counter, then see below,

   var cloneCount = 1;
   $("button").click(function(){
      $("#id").clone().attr('id', 'id'+ cloneCount++).insertAfter("#id");
   }); 

Generally the technique to avoid stack overflow is for recursive functions is called trampoline technique which is widely adopted by Java devs.

However, for C# there is a little helper method here that turns your recursive function to iterative without requiring to change logic or make the code in-comprehensible. C# is such a nice language that amazing stuff is possible with it.

It works by wrapping parts of the method by a helper method. For example the following recursive function:

int Sum(int index, int[] array)
{
 //This is the termination condition
 if (int >= array.Length)
 //This is the returning value when termination condition is true
 return 0;

//This is the recursive call
 var sumofrest = Sum(index+1, array);

//This is the work to do with the current item and the
 //result of recursive call
 return array[index]+sumofrest;
}

Turns into:

int Sum(int[] ar)
{
 return RecursionHelper<int>.CreateSingular(i => i >= ar.Length, i => 0)
 .RecursiveCall((i, rv) => i + 1)
 .Do((i, rv) => ar[i] + rv)
 .Execute(0);
}

You can do this with jquery just visit http://jquery.com/ to get the link then do something like this

<a id="show_image">Show Image</a>
<img id="my_images" style="display:none" src="http://myimages.com/img.png">

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
   $(document).ready(function(){
      $('#show_image').on("click", function(){
         $('#my_images').show('slow');
      });
   });
</script>

or if you would like the link to turn the image on and off do this

<a id="show_image">Show Image</a>
<img id="my_images" style="display:none;" src="http://myimages.com/img.png">

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
   $(document).ready(function(){
      $('#show_image').on("click", function(){
         $('#my_images').toggle();
      });
   });
</script>

This answer came up when searching for "java invert boolean function". The example below will prevent certain static analysis tools from failing builds due to branching logic. This is useful if you need to invert a boolean and haven't built out comprehensive unit tests ;)

Boolean.valueOf(aBool).equals(false)

or alternatively:

Boolean.FALSE.equals(aBool)

or

Boolean.FALSE::equals

create view as

where 
e2.empno=e1.mgr)

1. Don’t. Use Ajax, put it in data-* attributes in your HTML, or something else meaningful. Using inline scripts makes your pages bigger, and could be insecure or still allow users to ruin layout, unless…

2. … you make a safer function:

   function inline_json_encode($obj) {
       return str_replace('<!--', '<\!--', json_encode($obj));
   }
   

This is a shorthand Ajax function, which is equivalent to:

$.ajax({  type: "POST",
           url: url,  
          data: { username: value_login.val(), firstname: value_firstname.val(), 
                  lastname: value_lastname.val(), email: value_email.val(),
                  password: value_password.val()
                },
          dataType: "json"
       success: success// -> call your func here  
      });

Hope This helps

If you have two facets hospital and room but want to rename just one, you can use:

facet_grid( hospital ~ room, labeller = labeller(hospital = as_labeller(hospital_names)))

For renaming two facets using the vector-based approach (as in naught101's answer), you can do:

facet_grid( hospital ~ room, labeller = labeller(hospital = as_labeller(hospital_names),
                                                 room = as_labeller(room_names)))

Personally I never round anything. Keep it as resolute as possible, since rounding is a bit of a red herring in CS anyway. But you do want to format data for your users, and to that end, I find that string.Format("{0:0.00}", number) is a good approach.

@Rynant 's solution worked for me. I had a couple of additional requirements though:

1. Don't PAUSE if encountered in bat file
2. Optionally, append bat file output to log file

Here's what I got working (finally):

[PS script code]

& runner.bat bat_to_run.bat logfile.txt

[runner.bat]

@echo OFF

REM This script can be executed from within a powershell script so that the bat file
REM passed as %1 will not cause execution to halt if PAUSE is encountered.
REM If {logfile} is included, bat file output will be appended to logfile.
REM
REM Usage:
REM runner.bat [path of bat script to execute] {logfile}

if not [%2] == [] GOTO APPEND_OUTPUT
@echo | call %1
GOTO EXIT

:APPEND_OUTPUT
@echo | call %1  1> %2 2>&1

:EXIT

As mentioned in other people's comments, the top solution given here was not working for me in Ansible 2.2, particularly when also using with_items.

It appears that OP's intended approach does work now with a slight change to the quoting of item.

- set_fact: something="{{ something + [ item ] }}"
  with_items:
    - one
    - two
    - three

And a longer example where I've handled the initial case of the list being undefined and added an optional when because that was also causing me grief:

- set_fact: something="{{ something|default([]) + [ item ] }}"
  with_items:
    - one
    - two
    - three
  when: item.name in allowed_things.item_list

Create an instance of OrientationEventListener class and enable it.

OrientationEventListener mOrientationEventListener = new OrientationEventListener(YourActivity.this) {
    @Override
    public void onOrientationChanged(int orientation) {
        Log.d(TAG,"orientation = " + orientation);
    }
};

if (mOrientationEventListener.canDetectOrientation())
    mOrientationEventListener.enable();

$('tr').click(function(){
 alert( $('tr').index(this) );
});

For first tr, it alerts 0. If you want to alert 1, you can add 1 to index.

Do not access or modify the collection in the Comparator. The comparator should be used only to determine which object is comes before another. The two objects that are to be compared are supplied as arguments.

Date itself is comparable, so, using generics:

class MovieComparator implements Comparator<Movie> {
    public int compare(Movie m1, Movie m2) {
       //possibly check for nulls to avoid NullPointerException
       return m1.getDate().compareTo(m2.getDate());
    }
}

And do not instantiate the comparator on each sort. Use:

private static final MovieComparator comparator = new MovieComparator();

A common practice is to hide joins in a view to present the user a more denormalized data model. Other uses involve security (for example by hiding certain columns and/or rows) or performance (in case of materialized views)

The following is a summary of what you need to do under OS X Mavericks (10.9). This is all summarized in

http://hints.macworld.com/article.php?story=20060825071728278

1. Go to Terminal->Preferences->Settings->Advanced.

   Under International, make sure the character encoding is set to Unicode (UTF-8).

   Also, and this is key: under Emulation, make sure that Escape non-ASCII input with Control-V is unchecked (i.e. is not set).

   These two settings fix things for Terminal.

2. Make sure your locale is set to something that ends in .UTF-8. Type locale and look at the LC_CTYPE line. If it doesn't say something like en_US.UTF-8 (the stuff before the dot might change if you are using a non-US-English locale), then in your Bash .profile or .bashrc in your home directory, add a line like this:

   export LC_CTYPE=en_US.UTF-8
   

   This will fix things for command-line programs in general.

3. Add the following lines to .inputrc in your home directory (create it if necessary):

   set meta-flag on
   set input-meta on
   set output-meta on
   set convert-meta off
   

   This makes Bash be eight-bit clean, so it will pass UTF-8 characters in and out without messing with them.

Keep in mind you will have to restart Bash (e.g. close and reopen the Terminal window) to get it to pay attention to all the settings you make in 2 and 3 above.

I have found a solution in Python that is working well !

from math import atan2,degrees

def GetAngleOfLineBetweenTwoPoints(p1, p2):
    return degrees(atan2(p2 - p1, 1))

print GetAngleOfLineBetweenTwoPoints(1,3)

Using !important is generally not a good idea in the code itself, but it can be useful in various overrides.

I use Firefox and a dotjs plugin which essentially can run your own custom JS or CSS code on specified websites automatically.

Here's the code for it I use on Twitter that makes the tweet input field always stay on my screen no matter how far I scroll, and for the hyperlinks to always remain the same color.

a, a * {
  color: rgb(34, 136, 85) !important;  
}

.count-inner {
 color: white !important;   
}

.timeline-tweet-box {
 z-index: 99 !important;
position: fixed !important;
left: 5% !important;   
}

Since, thankfully, Twitter developers don't use !important properties much, I can use it to guarantee that the specified styles will be definitely overridden, because without !important they were not overridden sometimes. It really came in handy for me there.

What you are trying to do can be simplified down to this.

$('input:text').bind('focus blur', function() {_x000D_
    $(this).toggleClass('red');_x000D_
});

input{_x000D_
    background:#FFFFEE;_x000D_
}_x000D_
.red{_x000D_
    background-color:red;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
_x000D_
<form>_x000D_
    <input class="calc_input" type="text" name="start_date" id="start_date" />_x000D_
    <input class="calc_input" type="text" name="end_date" id="end_date" />_x000D_
    <input class="calc_input" size="8" type="text" name="leap_year" id="leap_year" />_x000D_
</form>

I post the solution that worked for me !

var form = $('#checkboxList input[type="checkbox"]').map(function() {
               return { name: this.name, value: this.checked ? this.value : "false" };
            }).get();

var data = JSON.stringify(form);

data value is : "[{"name":"cb1","value":"false"},{"name":"cb2","value":"true"},{"name":"cb3","value":"false"},{"name":"cb4","value":"true"}]"

If you operate on a large dataset, it is very possible that arrays will be used. For me creating a few arrays from 500 000 rows and 30 columns worksheet caused this error. I solved it simply by using the line below to get rid of array which is no longer necessary to me, before creating another one:

Erase vArray

Also if only 2 columns out of 30 are used, it is a good idea to create two 1-column arrays instead of one with 30 columns. It doesn't affect speed, but there will be a difference in memory usage.

here is the best practiced method to center a div as position absolute

DEMO FIDDLE

code --

#header {
background:black;
height:90px;
width:100%;
position:relative; // you forgot this, this is very important
}

#logo {
background:red;
height:50px;
position:absolute;
width:50px;
margin: auto; // margin auto works just you need to put top left bottom right as 0
top:0;
bottom:0;
left:0;
right:0;
}

I was looking for an example that had default kwargs using type annotation:

def test_var_kwarg(a: str, b: str='B', c: str='', **kwargs) -> str:
     return ' '.join([a, b, c, str(kwargs)])

example:

>>> print(test_var_kwarg('A', c='okay'))
A B okay {}
>>> d = {'f': 'F', 'g': 'G'}
>>> print(test_var_kwarg('a', c='c', b='b', **d))
a b c {'f': 'F', 'g': 'G'}
>>> print(test_var_kwarg('a', 'b', 'c'))
a b c {}

As noted elsewhere the variation around the world is huge. And even if something that matches the pattern does not mean it exists.

Then, of course, there are many places where postcodes are not used (e.g. much or Ireland).

Note in 2018: readAsBinaryString is outdated. For use cases where previously you'd have used it, these days you'd use readAsArrayBuffer (or in some cases, readAsDataURL) instead.

readAsBinaryString says that the data must be represented as a binary string, where:

...every byte is represented by an integer in the range [0..255].

JavaScript originally didn't have a "binary" type (until ECMAScript 5's WebGL support of Typed Array* (details below) -- it has been superseded by ECMAScript 2015's ArrayBuffer) and so they went with a String with the guarantee that no character stored in the String would be outside the range 0..255. (They could have gone with an array of Numbers instead, but they didn't; perhaps large Strings are more memory-efficient than large arrays of Numbers, since Numbers are floating-point.)

If you're reading a file that's mostly text in a western script (mostly English, for instance), then that string is going to look a lot like text. If you read a file with Unicode characters in it, you should notice a difference, since JavaScript strings are UTF-16** (details below) and so some characters will have values above 255, whereas a "binary string" according to the File API spec wouldn't have any values above 255 (you'd have two individual "characters" for the two bytes of the Unicode code point).

If you're reading a file that's not text at all (an image, perhaps), you'll probably still get a very similar result between readAsText and readAsBinaryString, but with readAsBinaryString you know that there won't be any attempt to interpret multi-byte sequences as characters. You don't know that if you use readAsText, because readAsText will use an encoding determination to try to figure out what the file's encoding is and then map it to JavaScript's UTF-16 strings.

You can see the effect if you create a file and store it in something other than ASCII or UTF-8. (In Windows you can do this via Notepad; the "Save As" as an encoding drop-down with "Unicode" on it, by which looking at the data they seem to mean UTF-16; I'm sure Mac OS and *nix editors have a similar feature.) Here's a page that dumps the result of reading a file both ways:

If I use that with a "Testing 1 2 3" file stored in UTF-16, here are the results I get:

Text (13):

54 65 73 74 69 6e 67 20 31 20 32 20 33

Binary (28):

ff fe 54 00 65 00 73 00 74 00 69 00 6e 00 67 00 20 00 31 00 20 00 32 00 20 00 33 00

As you can see, readAsText interpreted the characters and so I got 13 (the length of "Testing 1 2 3"), and readAsBinaryString didn't, and so I got 28 (the two-byte BOM plus two bytes for each character).

* XMLHttpRequest.response with responseType = "arraybuffer" is supported in HTML 5.

** "JavaScript strings are UTF-16" may seem like an odd statement; aren't they just Unicode? No, a JavaScript string is a series of UTF-16 code units; you see surrogate pairs as two individual JavaScript "characters" even though, in fact, the surrogate pair as a whole is just one character. See the link for details.

This is a chained solution from all others, for example, when realpath fails, either because it is not installed or because it exits with error code, then, the next solution is attempted until it get the path right.

#!/bin/bash

function getabsolutepath() {
    local target;
    local changedir;
    local basedir;
    local firstattempt;

    target="${1}";
    if [ "$target" == "." ];
    then
        printf "%s" "$(pwd)";

    elif [ "$target" == ".." ];
    then
        printf "%s" "$(dirname "$(pwd)")";

    else
        changedir="$(dirname "${target}")" && basedir="$(basename "${target}")" && firstattempt="$(cd "${changedir}" && pwd)" && printf "%s/%s" "${firstattempt}" "${basedir}" && return 0;
        firstattempt="$(readlink -f "${target}")" && printf "%s" "${firstattempt}" && return 0;
        firstattempt="$(realpath "${target}")" && printf "%s" "${firstattempt}" && return 0;

        # If everything fails... TRHOW PYTHON ON IT!!!
        local fullpath;
        local pythoninterpreter;
        local pythonexecutables;
        local pythonlocations;

        pythoninterpreter="python";
        declare -a pythonlocations=("/usr/bin" "/bin");
        declare -a pythonexecutables=("python" "python2" "python3");

        for path in "${pythonlocations[@]}";
        do
            for executable in "${pythonexecutables[@]}";
            do
                fullpath="${path}/${executable}";

                if [[ -f "${fullpath}" ]];
                then
                    # printf "Found ${fullpath}\\n";
                    pythoninterpreter="${fullpath}";
                    break;
                fi;
            done;

            if [[ "${pythoninterpreter}" != "python" ]];
            then
                # printf "Breaking... ${pythoninterpreter}\\n"
                break;
            fi;
        done;

        firstattempt="$(${pythoninterpreter} -c "import os, sys; print( os.path.abspath( sys.argv[1] ) );" "${target}")" && printf "%s" "${firstattempt}" && return 0;
        # printf "Error: Could not determine the absolute path!\\n";
        return 1;
    fi
}

printf "\\nResults:\\n%s\\nExit: %s\\n" "$(getabsolutepath "./asdfasdf/ asdfasdf")" "${?}"

At least in the current versions of PHPMailers, there's a function clearReplyTos() to empty the reply-to array.

    $mail->ClearReplyTos();
