There is a far easier solution built into Android Studio, and it usually works for me without needing any brute force solution mentioned in other answers - so you should try this first:

click on the "gradle" symbol on the right side of Android Studio, and then on the "Refresh all Gradle projects" tool.

I like the conversion to an array, to be able to access individual elements:

sentence="this is a story"
stringarray=($sentence)

now you can access individual elements directly (it starts with 0):

echo ${stringarray[0]}

or convert back to string in order to loop:

for i in "${stringarray[@]}"
do
  :
  # do whatever on $i
done

Of course looping through the string directly was answered before, but that answer had the the disadvantage to not keep track of the individual elements for later use:

for i in $sentence
do
  :
  # do whatever on $i
done

See also Bash Array Reference.

If you are using python3.6 or later you can use f-string to do the conversion:

Binary to decimal:

>>> print(f'{0b1011010:#0}')
90

>>> bin_2_decimal = int(f'{0b1011010:#0}')
>>> bin_2_decimal
90

binary to octal hexa and etc.

>>> f'{0b1011010:#o}'
'0o132'  # octal

>>> f'{0b1011010:#x}'
'0x5a'   # hexadecimal

>>> f'{0b1011010:#0}'
'90'     # decimal

Pay attention to 2 piece of information separated by colon.

In this way, you can convert between {binary, octal, hexadecimal, decimal} to {binary, octal, hexadecimal, decimal} by changing right side of colon[:]

:#b -> converts to binary
:#o -> converts to octal
:#x -> converts to hexadecimal 
:#0 -> converts to decimal as above example

Try changing left side of colon to have octal/hexadecimal/decimal.

Try File > New > Project... > Android Project From Existing Code. Don't copy your project from pc into workspace, copy it elsewhere and let the eclipse copy it into workspace by menu commands above and checking copy in existing workspace.

Using tail -f output should work.

I think I found an easier way (for me anyway). Locate your javaw.exe file (either by searching for it or just where you installed it), then drag the javaw.exe file onto the eclipse.exe file and it will use it.

Scripts are usually loaded in the end of the html page, and MVC recommends the using of bundles, just saying. So my best bet is that your jquery.validate files got altered in some way or are not updated to the latest version, since they do validate e-mail inputs.

So you could either update/refresh your nuget package or write your own function, really.

Here's an example which you would add in an extra file after jquery.validate.unobtrusive:

$.validator.addMethod(
    "email",
    function (value, element) {
        return this.optional( element ) || /^[a-zA-Z0-9.!#$%&'*+\/=?^_`{|}~-]+@[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(?:\.[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?)*$/.test( value );
    },
    "This e-mail is not valid"
);

This is just a copy and paste of the current jquery.validate Regex, but this way you could set your custom error message/add extra methods to fields you might want to validate in the near future.

Inside the folder you want to be compressed, in terminal:

zip -r -X Archive.zip *

Where -X means: Exclude those invisible Mac resource files such as “_MACOSX” or “._Filename” and .ds store files

source

Note: Will only work for the folder and subsequent folder tree you are in and has to have the * wildcard.

In my case, I had to exclude an older hamcrest from junit-vintage:

I wasn't completely happy by the --allow-file-access-from-files solution, because I'm using Chrome as my primary browser, and wasn't really happy with this breach I was opening.

Now I'm using Canary ( the chrome beta version ) for my development with the flag on. And the mere Chrome version for my real blogging : the two browser don't share the flag !

There is a certain amount of confusion in the answers to this this question.

The top answer is currently a server-side solution which sets a flag in the http header and some comments are indicating that a solution using a meta tag just doesn't work.

I think this blog entry gives a nice overview of how to use compatibility meta information and in my experience works as described: http://blogs.msdn.com/b/cjacks/archive/2012/02/29/using-x-ua-compatible-to-create-durable-enterprise-web-applications.aspx

The main points:

• setting the information using a meta tag and in the header both works
• The meta tag takes precedence over the header
• The meta tag has to be the first tag, to make sure that the browser does not determine the rendering engine before based on heuristics

One important point (and I think lots of confusion comes from this point) is that IE has two "classes" of modes:

1. The document mode
2. The browser mode

The document mode determines the rendering engine (how is the web page rendered).

The Browser Mode determines what User-Agent (UA) string IE sends to servers, what Document Mode IE defaults to, and how IE evaluates Conditional Comments.

More on the information on document mode vs. browser mode can be found in this article: http://blogs.msdn.com/b/ie/archive/2010/06/16/ie-s-compatibility-features-for-site-developers.aspx?Redirected=true

In my experience the compatibility meta data will only influence the document mode. So if you are relying on browser detection this won't help you. But if you are using feature detection this should be the way to go.

So I would recommend using the meta tag (in the html page) using this syntax:

<meta http-equiv="X-UA-Compatible" content="IE=9,10" ></meta>

Notice: give a list of browser modes you have tested for.

The blog post also advices against the use of EmulateIEX. Here a quote:

That being said, one thing I do find strange is when an application requests EmulateIE7, or EmulateIE8. These emulate modes are themselves decisions. So, instead of being specific about what you want, you’re asking for one of two things and then determining which of those two things by looking elsewhere in the code for a DOCTYPE (and then attempting to understand whether that DOCTYPE will give you standards or quirks depending on its contents – another sometimes confusing task). Rather than do that, I think it makes significantly more sense to directly specify what you want, rather than giving a response that is itself a question. If you want IE7 standards, then use IE=7, rather than IE=EmulateIE7. (Note that this doesn’t mean you shouldn’t use a DOCTYPE – you should.)

Without the need of an external package:

if your date is in the following format:

myDate = as.POSIXct("2013-01-01")

Then to get the month number:

format(myDate,"%m")

And to get the month string:

format(myDate,"%B")

parseInt() with radix is a best solution (as was told by many):

But if you want to implement it without parseInt, here is an implementation:

  function bin2dec(num){
    return num.split('').reverse().reduce(function(x, y, i){
      return (y === '1') ? x + Math.pow(2, i) : x;
    }, 0);
  }

java.lang.Integer is not a super class of BigInteger. Both BigInteger and Integer do inherit from java.lang.Number, so you could cast to a java.lang.Number.

With the new @SpringBootTest annotation, I took this answer and modified it to use profiles with a @SpringBootApplication configuration class. The @Profile annotation is necessary so that this class is only picked up during the specific integration tests that need this, as other test configurations do different component scanning.

Here is the configuration class:

@Profile("specific-profile")
@SpringBootApplication(scanBasePackages={"com.myco.package1", "com.myco.package2"})
public class SpecificTestConfig {

}

Then, the test class references this configuration class:

@RunWith(SpringRunner.class)
@SpringBootTest(classes = { SpecificTestConfig.class })
@ActiveProfiles({"specific-profile"})
public class MyTest {

                acc.Append(c);

            return acc;
        }).ToString();

Add the UTC offset to the local time then convert it to the desired format with the toLocaleDateString() method of the Date object:

// Using the current date/time
let now_local = new Date();
let now_utc = new Date();

// Adding the UTC offset to create the UTC date/time
now_utc.setMinutes(now_utc.getMinutes() + now_utc.getTimezoneOffset())

// Specify the format you want
let date_format = {};
date_format.year = 'numeric';
date_format.month = 'numeric';
date_format.day = '2-digit';
date_format.hour = 'numeric';
date_format.minute = 'numeric';
date_format.second = 'numeric';

// Printing the date/time in UTC then local format
console.log('Date in UTC: ', now_utc.toLocaleDateString('us-EN', date_format));
console.log('Date in LOC: ', now_local.toLocaleDateString('us-EN', date_format));

I'm creating a date object defaulting to the local time. I'm adding the UTC off-set to it. I'm creating a date-formatting object. I'm displaying the UTC date/time in the desired format:

Assuming you want to assign false (if applicable) to matchtime, a simpler way of writing it would be..

matchtime = ((expiryDate - DateTime.Now).TotalDays < 30);

Postgres 9.4 or later

Use WITH ORDINALITY for set-returning functions:

When a function in the FROM clause is suffixed by WITH ORDINALITY, a bigint column is appended to the output which starts from 1 and increments by 1 for each row of the function's output. This is most useful in the case of set returning functions such as unnest().

In combination with the LATERAL feature in pg 9.3+, and according to this thread on pgsql-hackers, the above query can now be written as:

SELECT t.id, a.elem, a.nr
FROM   tbl AS t
LEFT   JOIN LATERAL unnest(string_to_array(t.elements, ','))
                    WITH ORDINALITY AS a(elem, nr) ON TRUE;

LEFT JOIN ... ON TRUE preserves all rows in the left table, even if the table expression to the right returns no rows. If that's of no concern you can use this otherwise equivalent, less verbose form with an implicit CROSS JOIN LATERAL:

SELECT t.id, a.elem, a.nr
FROM   tbl t, unnest(string_to_array(t.elements, ',')) WITH ORDINALITY a(elem, nr);

Or simpler if based off an actual array (arr being an array column):

SELECT t.id, a.elem, a.nr
FROM   tbl t, unnest(t.arr) WITH ORDINALITY a(elem, nr);

Or even, with minimal syntax:

SELECT id, a, ordinality
FROM   tbl, unnest(arr) WITH ORDINALITY a;

a is automatically table and column alias. The default name of the added ordinality column is ordinality. But it's better (safer, cleaner) to add explicit column aliases and table-qualify columns.

Postgres 8.4 - 9.3

With row_number() OVER (PARTITION BY id ORDER BY elem) you get numbers according to the sort order, not the ordinal number of the original ordinal position in the string.

You can simply omit ORDER BY:

SELECT *, row_number() OVER (PARTITION by id) AS nr
FROM  (SELECT id, regexp_split_to_table(elements, ',') AS elem FROM tbl) t;

While this normally works and I have never seen it fail in simple queries, PostgreSQL asserts nothing concerning the order of rows without ORDER BY. It happens to work due to an implementation detail.

To guarantee ordinal numbers of elements in the blank-separated string:

SELECT id, arr[nr] AS elem, nr
FROM  (
   SELECT *, generate_subscripts(arr, 1) AS nr
   FROM  (SELECT id, string_to_array(elements, ' ') AS arr FROM tbl) t
   ) sub;

Or simpler if based off an actual array:

SELECT id, arr[nr] AS elem, nr
FROM  (SELECT *, generate_subscripts(arr, 1) AS nr FROM tbl) t;

Related answer on dba.SE:

• How to preserve the original order of elements in an unnested array?

Postgres 8.1 - 8.4

None of these features are available, yet: RETURNS TABLE, generate_subscripts(), unnest(), array_length(). But this works:

CREATE FUNCTION f_unnest_ord(anyarray, OUT val anyelement, OUT ordinality integer)
  RETURNS SETOF record
  LANGUAGE sql IMMUTABLE AS
'SELECT $1[i], i - array_lower($1,1) + 1
 FROM   generate_series(array_lower($1,1), array_upper($1,1)) i';

Note in particular, that the array index can differ from ordinal positions of elements. Consider this demo with an extended function:

CREATE FUNCTION f_unnest_ord_idx(anyarray, OUT val anyelement, OUT ordinality int, OUT idx int)
  RETURNS SETOF record
  LANGUAGE sql IMMUTABLE AS
'SELECT $1[i], i - array_lower($1,1) + 1, i
 FROM   generate_series(array_lower($1,1), array_upper($1,1)) i';

SELECT id, arr, (rec).*
FROM  (
   SELECT *, f_unnest_ord_idx(arr) AS rec
   FROM  (VALUES (1, '{a,b,c}'::text[])  --  short for: '[1:3]={a,b,c}'
               , (2, '[5:7]={a,b,c}')
               , (3, '[-9:-7]={a,b,c}')
      ) t(id, arr)
   ) sub;

 id |       arr       | val | ordinality | idx
----+-----------------+-----+------------+-----
  1 | {a,b,c}         | a   |          1 |   1
  1 | {a,b,c}         | b   |          2 |   2
  1 | {a,b,c}         | c   |          3 |   3
  2 | [5:7]={a,b,c}   | a   |          1 |   5
  2 | [5:7]={a,b,c}   | b   |          2 |   6
  2 | [5:7]={a,b,c}   | c   |          3 |   7
  3 | [-9:-7]={a,b,c} | a   |          1 |  -9
  3 | [-9:-7]={a,b,c} | b   |          2 |  -8
  3 | [-9:-7]={a,b,c} | c   |          3 |  -7

Good answers, however don't forget about filter() from dplyr:

patterns <- c("A1", "A9", "A6")
>your_df
  FirstName Letter
1      Alex     A1
2      Alex     A6
3      Alex     A7
4       Bob     A1
5     Chris     A9
6     Chris     A6

result <- filter(your_df, grepl(paste(patterns, collapse="|"), Letter))

>result
  FirstName Letter
1      Alex     A1
2      Alex     A6
3       Bob     A1
4     Chris     A9
5     Chris     A6

.offset() will return the offset position of an element as a simple object, eg:

var position = $(element).offset(); // position = { left: 42, top: 567 }

You can use this return value to position other elements at the same spot:

$(anotherElement).css(position)

This one worked for me.

@ is a shortcut option for v-on. Use @ only when you want to execute some Vue methods. As you are not executing Vue methods, instead you are calling javascript function, you need to use onchange attribute to call javascript function

<select name="LeaveType" onchange="onChange(this.value)" class="form-control">
 <option value="1">Annual Leave/ Off-Day</option>
 <option value="2">On Demand Leave</option>
</select>

function onChange(value) {
  console.log(value);
}

If you want to call Vue methods, do it like this-

<select name="LeaveType" @change="onChange($event)" class="form-control">
 <option value="1">Annual Leave/ Off-Day</option>
 <option value="2">On Demand Leave</option>
</select>

new Vue({
  ...
  ...
  methods:{
    onChange:function(event){
       console.log(event.target.value);
    }
  }
})

You can use v-model data attribute on the select element to bind the value.

<select v-model="selectedValue" name="LeaveType" onchange="onChange(this.value)" class="form-control">
 <option value="1">Annual Leave/ Off-Day</option>
 <option value="2">On Demand Leave</option>
</select>

new Vue({
    data:{
        selectedValue : 1, // First option will be selected by default
    },
    ...
    ...
    methods:{
        onChange:function(event){
            console.log(this.selectedValue);
        }
    }
})

Hope this Helps :-)

You could do this in one of three ways:

1. Use single and double quotes together:

    print('"A word that needs quotation marks"')
    "A word that needs quotation marks"

2. Escape the double quotes within the string:

    print("\"A word that needs quotation marks\"")
    "A word that needs quotation marks" 

3. Use triple-quoted strings:

    print(""" "A word that needs quotation marks" """)
    "A word that needs quotation marks" 

For anyone having same error for the same reason in ADOS CI Build:

This question was the first I found when looking for help. I have an ADOS CI build pipeline where first Node.js tool installer task is used to install Node. Then npm task is used to install gulp (npm install -g gulp). Then the following Gulp task runs default-task from gulpfile.js. There's some gulp-sass stuff in it.

When I changed the Node.js tool to install 12.x latest node instead of an older one and the latest gulp version was 4.0.2. The result was the same error as described in the question.

What worked for me in this case was to downgrade node.js to latest 11.x version as was already suggested by Alphonse R. Dsouza and Aymen Yaseen. In this case though there's no need to use any commands they suggested, but rather just set the Node.js tool installer version spec to latest Node version from 11.x.

The exact version of Node.js that got installed and is working was 11.15.0. I didn't have to downgrade the Gulp.

    WebElement element = driver.findElement(locator);

The assertion will pass if the element is not present, otherwise it will fail.

If you are expecting double, decimal, float, integer why not use the one which accomodates all namely decimal (128 bits are enough for most numbers you are looking at).

instead of (double)value use decimal.Parse(value.ToString()) or Convert.ToDecimal(value)

A combination of @Jack's answer and @ranierbit's answer should do the trick.

Set the ng build flag for --output-hashing so:

Then add this class either in a service or in your app.module

@Injectable()
export class NoCacheHeadersInterceptor implements HttpInterceptor {
    intercept(req: HttpRequest<any>, next: HttpHandler) {
        const authReq = req.clone({
            setHeaders: {
                'Cache-Control': 'no-cache',
                 Pragma: 'no-cache'
            }
        });
        return next.handle(authReq);    
    }
}

Then add this to your providers in your app.module:

providers: [
  ... // other providers
  {
    provide: HTTP_INTERCEPTORS,
    useClass: NoCacheHeadersInterceptor,
    multi: true
  },
  ... // other providers
]

This should prevent caching issues on live sites for client machines

The advantage comes into account when the operations can be executed in parallel. (See http://java.dzone.com/articles/devoxx-2012-java-8-lambda-and - the section about internal and external iteration)

• The main advantage from my point of view is that the implementation of what is to be done within the loop can be defined without having to decide if it will be executed in parallel or sequential

• If you want your loop to be executed in parallel you could simply write

   joins.parallelStream().forEach(join -> mIrc.join(mSession, join));
  

  You will have to write some extra code for thread handling etc.

Note: For my answer I assumed joins implementing the java.util.Stream interface. If joins implements only the java.util.Iterable interface this is no longer true.

I was pretty sure that you need to specify the NOLOCK for each JOIN in the query. But my experience was limited to SQL Server 2005.

When I looked up MSDN just to confirm, I couldn't find anything definite. The below statements do seem to make me think, that for 2008, your two statements above are equivalent though for 2005 it is not the case:

[SQL Server 2008 R2]

All lock hints are propagated to all the tables and views that are accessed by the query plan, including tables and views referenced in a view. Also, SQL Server performs the corresponding lock consistency checks.

[SQL Server 2005]

In SQL Server 2005, all lock hints are propagated to all the tables and views that are referenced in a view. Also, SQL Server performs the corresponding lock consistency checks.

Additionally, point to note - and this applies to both 2005 and 2008:

The table hints are ignored if the table is not accessed by the query plan. This may be caused by the optimizer choosing not to access the table at all, or because an indexed view is accessed instead. In the latter case, accessing an indexed view can be prevented by using the OPTION (EXPAND VIEWS) query hint.

You can use the line below which goes into a closure (viewDidLoad, didLayOutSubViews, etc):

self.view.backgroundColor = .redColor()

Some good starting points could be GLFont, OpenGL Font Survey and NeHe Tutorial for Bitmap Fonts (Windows).

Note that bitmaps are not the only way of achieving text in OpenGL as mentioned in the font survey.

That solution will open up a new browser window without the normal features such as address bar and similar.

To implement a modal popup, I suggest you to take a look at jQuery and SimpleModal, which is really slick.

(Here are some simple demos using SimpleModal: http://www.ericmmartin.com/projects/simplemodal-demos/)

I had fix this with adduser *username* dialout. I never had this error again, even though previously the only way to get it to work was to reboot the PC or unplug and replug the usb to serial adapter.

Faced same issue, Try using JPG format !! What worked for me here was using a jpg file instead of PNG as jpg files don't use alpha or transparency features. I did it via online image converter or you can also open the image in preview and then File->Export and uncheck alpha as option to save the image and use this image.

Try CSS:

<h2 style="color:#069">Process Report</h2>

If you have more than one h2 tags which should have the same color add a style tag to the head tag like this:

<style type="text/css">
h2 {
    color:#069;
}
</style>

I tried re-creating this, and .someclass.notip was being generated for me but .someclass:not(.notip) was not, for as long as I did not have the @mixin tip() defined. Once I had that, it all worked.

http://sassmeister.com/gist/9775949

$dropdown-width: 100px;
$comp-tip: true;

@mixin tip($pos:right) {

}

@mixin dropdown-pos($pos:right) {
  &:not(.notip) {
    @if $comp-tip == true{
      @if $pos == right {
        top:$dropdown-width * -0.6;
        background-color: #f00;
        @include tip($pos:$pos);
      }
    }
  }
  &.notip {
    @if $pos == right {
      top: 0;
      left:$dropdown-width * 0.8;
      background-color: #00f;
    }
  }
}

.someclass { @include dropdown-pos(); }

EDIT: http://sassmeister.com/ is a good place to debug your SASS because it gives you error messages. Undefined mixin 'tip'. it what I get when I remove @mixin tip($pos:right) { }

Can't you style the forms themselves? Then, style the divs accordingly.

form
{
    /* styles */
}

You can always overrule inherited styles by making it important:

form
{
    /* styles */ !important
}

this might be a dirty code but i think it can suffice

<div v-for="(counter in counters">
{{ counter }}) {{ userlist[counter-1].name }}
</div>

on your script add this one

data(){return {userlist: [],user_id: '',counters: 0,edit: false,}},

you can simply use This statement for example if your table name is School. Before insertion make sure identity_insert is set to ON and after insert query turn identity_insert OFF

SET IDENTITY_INSERT School ON
/*
  insert query
  enter code here
*/
SET IDENTITY_INSERT School OFF

For Django version 1.7, if above solutions dont work then try the following

in settings.py add

#For email
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'

EMAIL_USE_TLS = True

EMAIL_HOST = 'smtp.gmail.com'

EMAIL_HOST_USER = '[email protected]'

#Must generate specific password for your app in [gmail settings][1]
EMAIL_HOST_PASSWORD = 'app_specific_password'

EMAIL_PORT = 587

#This did the trick
DEFAULT_FROM_EMAIL = EMAIL_HOST_USER

The last line did the trick for django 1.7

It depends what you mean by "it". The iterator knows what index it's reached, yes - in the case of a List<T> or an array. But there's no general index within IEnumerator<T>. Whether it's iterating over an indexed collection or not is up to the implementation. Plenty of collections don't support direct indexing.

(In fact, foreach doesn't always use an iterator at all. If the compile-time type of the collection is an array, the compiler will iterate over it using array[0], array[1] etc. Likewise the collection can have a method called GetEnumerator() which returns a type with the appropriate members, but without any implementation of IEnumerable/IEnumerator in sight.)

Options for maintaining an index:

• Use a for loop
• Use a separate variable

• Use a projection which projects each item to an index/value pair, e.g.

   foreach (var x in list.Select((value, index) => new { value, index }))
   {
       // Use x.value and x.index in here
   }
  

• Use my SmartEnumerable class which is a little bit like the previous option

All but the first of these options will work whether or not the collection is naturally indexed.

Bind the event to a parent which already exists:

$(document).on("click", "selector", function() {
    // Your code here
});

Select the tableview in your storyboard and ensure that the style is set to "Plain", instead of "Grouped". You can find this setting in the attributes Inspector tab.

Go to the Run->Run Configuration-> now

Under C/C++ Application you will see the name of your executable + Debug (if not, click over C/C++ Application a couple of times). Select the name (in this case projectTitle+Debug).

Under this in main Tab -> C/C++ application -> Search your project -> in binaries select your binary titled by your project....

anyItem is a method and the System.out.println call is after your return statement so that won't compile anyway since it is unreachable.

Might want to re-write it like:

import java.util.ArrayList;
import java.util.Random;

public class Catalogue
{
    private Random randomGenerator;
    private ArrayList<Item> catalogue;

    public Catalogue()
    { 
        catalogue = new ArrayList<Item>();
        randomGenerator = new Random();
    }

    public Item anyItem()
    {
        int index = randomGenerator.nextInt(catalogue.size());
        Item item = catalogue.get(index);
        System.out.println("Managers choice this week" + item + "our recommendation to you");
        return item;
    }
}

Use Spring's "PropertyPlaceholderConfigurer" class

A simple example showing property file read dynamically as bean's property

<bean id="placeholderConfig"
        class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

        <list>
            <value>/WEB-INF/classes/config_properties/dev/database.properties</value>
        </list>
    </property> 
</bean>

<bean id="devDataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
    <property name="driverClass" value="${dev.app.jdbc.driver}"/>
    <property name="jdbcUrl" value="${dev.app.jdbc.url}"/>
    <property name="user" value="${dev.app.jdbc.username}"/>

Use Modernizr for detection of feature capabilities. In general jQuery offers to detect browser features: http://api.jquery.com/jQuery.support/. However, hashchange is not on the list.

The wiki of Modernizr offers a list of libraries to add HTML5 capabilities to old browsers. The list for hashchange includes a pointer to the project HTML5 History API, which seems to offer the functionality you would need if you wanted to emulate the behavior in old browsers.

@glglgl already explained why what you were trying to do was not working. Actually, if you are really aiming at defining a variable in a header, you can trick using some preprocessor directives:

file1.c:

#include <stdio.h>

#define DEFINE_I
#include "global.h"

int main()
{
    printf("%d\n",i);
    foo();
    return 0;
}

file2.c:

#include <stdio.h>
#include "global.h"

void foo()
{
    i = 54;
    printf("%d\n",i);
}

global.h:

#ifdef DEFINE_I
int i = 42;
#else
extern int i;
#endif

void foo();

In this situation, i is only defined in the compilation unit where you defined DEFINE_I and is declared everywhere else. The linker does not complain.

I have seen this a couple of times before where an enum was declared in a header, and just below was a definition of a char** containing the corresponding labels. I do understand why the author preferred to have that definition in the header instead of putting it into a specific source file, but I am not sure whether the implementation is so elegant.

If you want to set the column you filter on as a new index, you could also consider to use .filter; if you want to keep it as a separate column then str.contains is the way to go.

Let's say you have

df = pd.DataFrame({'vals': [1, 2, 3, 4, 5], 'ids': [u'aball', u'bball', u'cnut', u'fball', 'ballxyz']})

       ids  vals
0    aball     1
1    bball     2
2     cnut     3
3    fball     4
4  ballxyz     5

and your plan is to filter all rows in which ids contains ball AND set ids as new index, you can do

df.set_index('ids').filter(like='ball', axis=0)

which gives

         vals
ids          
aball       1
bball       2
fball       4
ballxyz     5

But filter also allows you to pass a regex, so you could also filter only those rows where the column entry ends with ball. In this case you use

df.set_index('ids').filter(regex='ball$', axis=0)

       vals
ids        
aball     1
bball     2
fball     4

Note that now the entry with ballxyz is not included as it starts with ball and does not end with it.

If you want to get all entries that start with ball you can simple use

df.set_index('ids').filter(regex='^ball', axis=0)

yielding

         vals
ids          
ballxyz     5

The same works with columns; all you then need to change is the axis=0 part. If you filter based on columns, it would be axis=1.

You've got a couple regexes now which will do what you want, so that's adequately covered.

What hasn't been mentioned is why your attempt won't work: Inside a character class, $ (as well as ^, ., and /) has no special meaning, so [/$] matches either a literal / or a literal $ rather than terminating the regex (/) or matching end-of-line ($).

I've been interested in the original question here and related ones.

For an answer, this week I did some experiments with XCOPY.

To help answer the original question, here I post the results of my experiments.

I did the experiments on Windows 7 64 bit Professional SP1 with the copy of XCOPY that came with the operating system.

For the experiments, I wrote some code in the scripting language Open Object Rexx and the editor macro language Kexx with the text editor KEdit.

XCOPY was called from the Rexx code. The Kexx code edited the screen output of XCOPY to focus on the crucial results.

The experiments all had to do with using XCOPY to copy one directory with several files and subdirectories.

The experiments consisted of 10 cases. Each case adjusted the arguments to XCOPY and called XCOPY once. All 10 cases were attempting to do the same copying operation.

Here are the main results:

(1) Of the 10 cases, only three did copying. The other 7 cases right away, just from processing the arguments to XCOPY, gave error messages, e.g.,

Invalid path

Access denied

with no files copied.

Of the three cases that did copying, they all did the same copying, that is, gave the same results.

(2) If want to copy a directory X and all the files and directories in directory X, in the hierarchical file system tree rooted at directory X, then apparently XCOPY -- and this appears to be much of the original question -- just will NOT do that.

One consequence is that if using XCOPY to copy directory X and its contents, then CAN copy the contents but CANNOT copy the directory X itself; thus, lose the time-date stamp on directory X, its archive bit, data on ownership, attributes, etc.

Of course if directory X is a subdirectory of directory Y, an XCOPY of Y will copy all of the contents of directory Y WITH directory X. So in this way can get a copy of directory X. However, the copy of directory X will have its time-date stamp of the time of the run of XCOPY and NOT the time-date stamp of the original directory X.

This change in time-date stamps can be awkward for a copy of a directory with a lot of downloaded Web pages: The HTML file of the Web page will have its original time-date stamp, but the corresponding subdirectory for files used by the HTML file will have the time-date stamp of the run of XCOPY. So, when sorting the copy on time date stamps, all the subdirectories, the HTML files and the corresponding subdirectories, e.g.,

x.htm

x_files

can appear far apart in the sort on time-date.

Hierarchical file systems go way back, IIRC to Multics at MIT in 1969, and since then lots of people have recognized the two cases, given a directory X, (i) copy directory X and all its contents and (ii) copy all the contents of X but not directory X itself. Well, if only from the experiments, XCOPY does only (ii).

So, the results of the 10 cases are below. For each case, in the results the first three lines have the first three arguments to XCOPY. So, the first line has the tree name of the directory to be copied, the 'source'; the second line has the tree name of the directory to get the copies, the 'destination', and the third line has the options for XCOPY. The remaining 1-2 lines have the results of the run of XCOPY.

One big point about the options is that options /X and /O result in result

Access denied

To see this, compare case 8 with the other cases that were the same, did not have /X and /O, but did copy.

These experiments have me better understand XCOPY and contribute an answer to the original question.

Try this one for current selection:

Sub A_SelectAllMakeTable2()
    Dim tbl As ListObject
    Set tbl = ActiveSheet.ListObjects.Add(xlSrcRange, Selection, , xlYes)
    tbl.TableStyle = "TableStyleMedium15"
End Sub

or equivalent of your macro (for Ctrl+Shift+End range selection):

Sub A_SelectAllMakeTable()
    Dim tbl As ListObject
    Dim rng As Range

    Set rng = Range(Range("A1"), Range("A1").SpecialCells(xlLastCell))
    Set tbl = ActiveSheet.ListObjects.Add(xlSrcRange, rng, , xlYes)
    tbl.TableStyle = "TableStyleMedium15"
End Sub

No, [^\x20-\x7E] is not ASCII.

This is real ASCII:

 [^\x00-\x7F]

Otherwise, it will trim out newlines and other special characters that are part of the ASCII table!

Here another method but it is little worse compare to other.

List<int> i=original.Take(original.count).ToList();

I found this very helpful, check it: http://cdnjs.com/libraries/bootstrap-rtl

For me, problem was Typo in location path.

Maybe first thing to check out for this kind of problem

Is path to project.

If you use ThreadPoolExecutor, and you use submit() method, it will give you a Future back. You can call cancel() on the returned Future to stop your Runnable task.

Try to use the latest com.fasterxml.jackson.core/jackson-databind. I upgraded it to 2.9.4 and it works now.

<!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind -->
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.9.4</version>
</dependency>

The answers above work ($ for empty), but I just tried this and it also works to just leave empty like so:

/\A(INTENSE_EMAIL_REGEX|)\z/i

Same thing in reverse order

/\A(|INTENSE_EMAIL_REGEX)\z/i

Another option is to use an array, e.g. void method(SomeClass[] v) { v[0] = ...; } but 1) the array must be initialized before method invoked, 2) still one cannot implement e.g. swap method in this way... This way is used in JDK, e.g. in java.util.concurrent.atomic.AtomicMarkableReference.get(boolean[]).

I created a extension method that is much simpiler than the answers that are posted. and the aspect ratio is applied without cropping the image.

public static Image Resize(this Image image, int width, int height) {
     var scale = Math.Min(height / (float)image.Height, width / (float)image.Width);
     return image.GetThumbnailImage((int)(image.Width * scale), (int)(image.Height * scale), () => false, IntPtr.Zero);
}

Example usage:

using (var img = Image.FromFile(pathToOriginalImage)) {
    using (var thumbnail = img.Resize(60, 60)){
        // Here you can do whatever you need to do with thumnail
    }
}

For Chrome on Android, you can use the -webkit-tap-highlight-color CSS property:

-webkit-tap-highlight-color is a non-standard CSS property that sets the color of the highlight that appears over a link while it's being tapped. The highlighting indicates to the user that their tap is being successfully recognized, and indicates which element they're tapping on.

To remove the highlighting completely, you can set the value to transparent:

-webkit-tap-highlight-color: transparent;

Be aware that this might have consequences on accessibility: see outlinenone.com

You may set a transparent background color for the selected cells as following:

DataGridView.RowsDefaultCellStyle.SelectionBackColor = System.Drawing.Color.Transparent;

I found adding constraint programmatically much easier than in storyboard.

    var leadingMargin = NSLayoutConstraint(item: self.tableView, attribute: NSLayoutAttribute.LeadingMargin, relatedBy: NSLayoutRelation.Equal, toItem: self.mView, attribute: NSLayoutAttribute.LeadingMargin, multiplier: 1, constant: 0.0)

    var trailingMargin = NSLayoutConstraint(item: self.tableView, attribute: NSLayoutAttribute.TrailingMargin, relatedBy: NSLayoutRelation.Equal, toItem: mView, attribute: NSLayoutAttribute.TrailingMargin, multiplier: 1, constant: 0.0)

    var height = NSLayoutConstraint(item: self.tableView, attribute: NSLayoutAttribute.Height, relatedBy: NSLayoutRelation.Equal, toItem: nil, attribute: NSLayoutAttribute.NotAnAttribute, multiplier: 1, constant: screenSize.height - 55)

    var bottom = NSLayoutConstraint(item: self.tableView, attribute: NSLayoutAttribute.BottomMargin, relatedBy: NSLayoutRelation.Equal, toItem: self.mView, attribute: NSLayoutAttribute.BottomMargin, multiplier: 1, constant: screenSize.height - 200)

    var top = NSLayoutConstraint(item: self.tableView, attribute: NSLayoutAttribute.TopMargin, relatedBy: NSLayoutRelation.Equal, toItem: self.mView, attribute: NSLayoutAttribute.TopMargin, multiplier: 1, constant: 250)

    self.view.addConstraint(leadingMargin)
    self.view.addConstraint(trailingMargin)
    self.view.addConstraint(height)
    self.view.addConstraint(bottom)
    self.view.addConstraint(top)

You can make use of java.net.URL and/or java.net.URLConnection.

URL url = new URL("https://stackoverflow.com");

try (BufferedReader reader = new BufferedReader(new InputStreamReader(url.openStream(), "UTF-8"))) {
    for (String line; (line = reader.readLine()) != null;) {
        System.out.println(line);
    }
}

Also see the Oracle's simple tutorial on the subject. It's however a bit verbose. To end up with less verbose code, you may want to consider Apache HttpClient instead.

By the way: if your next question is "How to process HTML result?", then the answer is "Use a HTML parser. No, don't use regex for this.".

I worked with some self-taught programmers who read stuff like "learn javascript in 0.01 days". Everyday was worth it's share of thedailywtf.com.

Besides, at a job inteview you get asked "how much javascript experience do you have?", your answer "0.01 days".

so good luck but I hope our path won't cross before a few more years

Since version 1.3.0 AngularJS introduced extra filter parameter timezone, like following:

{{ date_expression | date : format : timezone}}

But in versions 1.3.x only supported timezone is UTC, which can be used as following:

{{ someDate | date: 'MMM d, y H:mm:ss' : 'UTC' }}

Since version 1.4.0-rc.0 AngularJS supports other timezones too. I was not testing all possible timezones, but here's for example how you can get date in Japan Standard Time (JSP, GMT +9):

{{ clock | date: 'MMM d, y H:mm:ss' : '+0900' }}

Here you can find documentation of AngularJS date filters.

NOTE: this is working only with Angular 1.x

Here's working example

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

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

Examples:

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

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

A hard-coded constant^[1]:

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

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

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

If you are creating an array whose main feature is it's length, rather than the value of each index, defining an array as var a=Array(length); is appropriate.

eg-

String.prototype.repeat= function(n){
    n= n || 1;
    return Array(n+1).join(this);
}

Found the port esp32 was connected to by -

ls /dev/*

You would get a long list and you can find the port you need

import matplotlib.pyplot as plt # For ploting
import numpy as np # to work with numerical data efficiently

fs = 100 # sample rate 
f = 2 # the frequency of the signal

x = np.arange(fs) # the points on the x axis for plotting
# compute the value (amplitude) of the sin wave at the for each sample
y = np.sin(2*np.pi*f * (x/fs)) 

#this instruction can only be used with IPython Notbook. 
% matplotlib inline
# showing the exact location of the smaples
plt.stem(x,y, 'r', )
plt.plot(x,y)

Using a generator function you could iterate over deep key-values.

function * deepEntries(obj) { _x000D_
    for(let [key, value] of Object.entries(obj)) {_x000D_
        if (typeof value !== 'object') _x000D_
            yield [key, value]_x000D_
        else _x000D_
            for(let entries of deepEntries(value))_x000D_
                yield [key, ...entries]_x000D_
    }_x000D_
}_x000D_
_x000D_
const dictionary = {_x000D_
    "data": [_x000D_
        {"id":"0","name":"ABC"},_x000D_
        {"id":"1","name":"DEF"}_x000D_
    ],_x000D_
    "images": [_x000D_
        {"id":"0","name":"PQR"},_x000D_
        {"id":"1","name":"xyz"}_x000D_
    ]_x000D_
}_x000D_
_x000D_
for(let entries of deepEntries(dictionary)) {_x000D_
    const key = entries.slice(0, -1).join('.')_x000D_
    const value = entries[entries.length-1]_x000D_
    console.log(key, value)_x000D_
}

You can get the coordinate of the target element and set the scroll position to it. But this is so complicated.

Here is a lazier way to do that:

function jump(h){
    var url = location.href;               //Save down the URL without hash.
    location.href = "#"+h;                 //Go to the target element.
    history.replaceState(null,null,url);   //Don't like hashes. Changing it back.
}

This uses replaceState to manipulate the url. If you also want support for IE, then you will have to do it the complicated way:

function jump(h){
    var top = document.getElementById(h).offsetTop; //Getting Y of target element
    window.scrollTo(0, top);                        //Go there directly or some transition
}?

Demo: http://jsfiddle.net/DerekL/rEpPA/
Another one w/ transition: http://jsfiddle.net/DerekL/x3edvp4t/

You can also use .scrollIntoView:

document.getElementById(h).scrollIntoView();   //Even IE6 supports this

_{(Well I lied. It's not complicated at all.)}

I think init_js should use declare instead of local!

function scan3() {
    declare -n outvar=$1    # -n makes it a nameref.
    local nl=$'\x0a'
    outvar="output${nl}${nl}"  # two total. quotes preserve newlines
}

Alternatively:

1. Save current changes to a temp stash:

   $ git stash

2. Create a new branch based on this stash, and switch to the new branch:

   $ git stash branch <new-branch> stash@{0}

Tip: use tab key to reduce typing the stash name.

Inside class definitions you can only declare static members. They have to be defined outside of the class. For compile-time integral constants the standard makes the exception that you can "initialize" members. It's still not a definition, though. Taking the address would not work without definition, for example.

I'd like to mention that I don't see the benefit of using std::string over const char[] for constants. std::string is nice and all but it requires dynamic initialization. So, if you write something like

const std::string foo = "hello";

at namespace scope the constructor of foo will be run right before execution of main starts and this constructor will create a copy of the constant "hello" in the heap memory. Unless you really need RECTANGLE to be a std::string you could just as well write

// class definition with incomplete static member could be in a header file
class A {
    static const char RECTANGLE[];
};

// this needs to be placed in a single translation unit only
const char A::RECTANGLE[] = "rectangle";

There! No heap allocation, no copying, no dynamic initialization.

Cheers, s.

After some trials, knowing that I had all the factors stated in this thread and other threads properly configured, I still got this error in Android Studio.

Even after installing externally, it seems Android Studio could not discover that HAXM is already installed, unless it gets to install it itself.

As a solution that worked for me, under User\AppData\Local\Android\sdk\extras\intel\Hardware_Accelerated_Execution_Manager which android has downloaded when attempting to install HAXM, click the installer and uninstall the software, then re-try from Android Studio to install it, it should work now.

Plain old Java on plain old Java 7 and no other dependencies demonstrates the difference...

I put file.txt in c:\temp\ and I put c:\temp\ on the classpath.

There is only one case where there is a difference between the two call.

class J {

 public static void main(String[] a) {
    // as "absolute"

    // ok   
    System.err.println(J.class.getResourceAsStream("/file.txt") != null); 

    // pop            
    System.err.println(J.class.getClassLoader().getResourceAsStream("/file.txt") != null); 

    // as relative

    // ok
    System.err.println(J.class.getResourceAsStream("./file.txt") != null); 

    // ok
    System.err.println(J.class.getClassLoader().getResourceAsStream("./file.txt") != null); 

    // no path

    // ok
    System.err.println(J.class.getResourceAsStream("file.txt") != null); 

   // ok
   System.err.println(J.class.getClassLoader().getResourceAsStream("file.txt") != null); 
  }
}

If the content is just a very simple html, the simplest way is to remove the iframe with javascript

HTML code:

<div class="iframe">
    <iframe src="./mypage.html" frameborder="0" onload="removeIframe(this);"></iframe>
</div>

Javascript code:

function removeIframe(obj) {
    var iframeDocument = obj.contentDocument || obj.contentWindow.document;
    var mycontent = iframeDocument.getElementsByTagName("body")[0].innerHTML;
    obj.remove();
    document.getElementsByClassName("iframe")[0].innerHTML = mycontent;
}

Functionality is supposed to be broken in jQuery 1.5.

Since jQuery 1.5.1 you should use xhrFields param.

$.ajaxSetup({
    type: "POST",
    data: {},
    dataType: 'json',
    xhrFields: {
       withCredentials: true
    },
    crossDomain: true
});

Docs: http://api.jquery.com/jQuery.ajax/

Reported bug: http://bugs.jquery.com/ticket/8146

The guide you linked now has a Tear Down section:

Talking to the master with the appropriate credentials, run:

kubectl drain <node name> --delete-local-data --force --ignore-daemonsets
kubectl delete node <node name>

Then, on the node being removed, reset all kubeadm installed state:

kubeadm reset

You need to do the following

git fetch -p

This will update the local database of remote branches.

Simple line:

bodyDoc.LoadXml(new MemoryStream(Encoding.Unicode.GetBytes(body)));

You can use

call script.bat

or just

script.bat

Setting project's SDK in IntelliJ (File > Project Structure > Project:Project SDK) worked for me

Using double to store large integers is dubious; the largest integer that can be stored reliably in double is much smaller than DBL_MAX. You should use long long, and if that's not enough, you need your own arbitrary-precision code or an existing library.

The asterisk (*) means "zero or more of the previous item".

If you want to match any single character use

sed -i 's/string-./string-0/g' file.txt

If you want to match any string (i.e. any single character zero or more times) use

sed -i 's/string-.*/string-0/g' file.txt

A bit late to the party, but Krux has created a script for this, called Postscribe. We were able to use this to get past this issue.

As said above -- use Euclidean distance.

from math import hypot

def in_radius(c_x, c_y, r, x, y):
    return math.hypot(c_x-x, c_y-y) <= r

ArrayList<String>[][] list = new ArrayList[10][10];
list[0][0] = new ArrayList<>();
list[0][0].add("test");

Try adding this to your source:

debugger;

It works in most, if not all browsers. Just place it somewhere in your code, and it will act like a breakpoint.

If you have array of custom Objects, you can search by specific property like this:

if let index = doctorsInArea.firstIndex(where: {$0.id == doctor.id}){
    doctorsInArea.remove(at: index)
}

or if you want to search by name for example

if let index = doctorsInArea.firstIndex(where: {$0.name == doctor.name}){
    doctorsInArea.remove(at: index)
}

If your trying to fade the backgound image but leave the foreground text/images you could use css to separate the background image into a new div and position it over the div containing the text/images then fade the background div.

your div looks like this:

<div class="readonly_label" id="field-function_purpose">Other</div>

With jquery you can easily get inner content:

Use .html() : HTML contents of the first element in the set of matched elements or set the HTML contents of every matched element.

var text = $('#field-function_purpose').html(); 

Read more about jquery .html()

or

Use .text() : Get the combined text contents of each element in the set of matched elements, including their descendants, or set the text contents of the matched elements.

var text = $('#field-function_purpose').text();

Read more about jquery .text()

var newTH = document.createElement('th');
newTH.setAttribute("onclick", "removeColumn(#)");
newTH.setAttribute("id", "#");

function removeColumn(#){
// remove column #
}

You missed the * in front of NgIf (like we all have, dozens of times):

<div *ngIf="answer.accepted">&#10004;</div>

Without the *, Angular sees that the ngIf directive is being applied to the div element, but since there is no * or <template> tag, it is unable to locate a template, hence the error.

If you get this error with Angular v5:

Error: StaticInjectorError[TemplateRef]:
  StaticInjectorError[TemplateRef]:
    NullInjectorError: No provider for TemplateRef!

You may have <template>...</template> in one or more of your component templates. Change/update the tag to <ng-template>...</ng-template>.

I found the answer I was looking for. The thing to use here is the construct of

\left \middle \right

For example, in this case, two possible solutions are:

$\left( {\frac{a_1}{a_2}} \middle/ {\frac{b_1}{b_2}} \right) $

Or, in case the brackets are not necessary:

$\left. {\frac{a_1}{a_2}} \middle/ {\frac{b_1}{b_2}} \right. $

Use ` backticks for MYSQL reserved words...

table name "table" is reserved word for MYSQL...

so your query should be as follows...

$sql="INSERT INTO `table` (`username`, `password`)
VALUES
('$_POST[username]','$_POST[password]')";

this states that Account.deposit(Double.MAX_VALUE); it is setting deposit value to MAX value of Double dataType.to procced for running tests.

Just adding the #include <math.h> in c source file and -lm in Makefile at the end will work for me.

    gcc -pthread -o p3 p3.c -lm

The safest way to have a PDF display instead of download seems to be embedding it using an object or iframe element. There are also 3rd party solutions like Google's PDF viewer.

See Best Way to Embed PDF in HTML for an overview.

There's also DoPDF, a Java based In-browser PDF viewer. I can't speak to its quality but it looks interesting.

Public IP Addresses

https://github.com/stephenlb/geo-ip will generate a list of Valid IP Public Addresses including Localities.

'1.0.0.0/8' to '191.0.0.0/8' are the valid public IP Address range exclusive of the reserved Private IP Addresses as follows:

import iptools
## Private IP Addresses
private_ips = iptools.IpRangeList(
    '0.0.0.0/8',      '10.0.0.0/8',     '100.64.0.0/10', '127.0.0.0/8',
    '169.254.0.0/16', '172.16.0.0/12',  '192.0.0.0/24',  '192.0.2.0/24',
    '192.88.99.0/24', '192.168.0.0/16', '198.18.0.0/15', '198.51.100.0/24',
    '203.0.113.0/24', '224.0.0.0/4',    '240.0.0.0/4',   '255.255.255.255/32'
)

IP Generator

Generates a JSON dump of IP Addresses and associated Geo information. Note that the valid public IP Address range is from '1.0.0.0/8' to '191.0.0.0/8' excluding the reserved Private IP Address ranges shown lower down in this readme.

docker build -t geo-ip .
docker run -e IPRANGE='54.0.0.0/30' geo-ip               ## a few IPs
docker run -e IPRANGE='54.0.0.0/26' geo-ip               ## a few more IPs
docker run -e IPRANGE='54.0.0.0/16' geo-ip               ## a lot more IPs
docker run -e IPRANGE='0.0.0.0/0'   geo-ip               ## ALL IPs ( slooooowwwwww )
docker run -e IPRANGE='0.0.0.0/0'   geo-ip > geo-ip.json ## ALL IPs saved to JSON File
docker run geo-ip 

A little faster option for scanning all valid public addresses:

for i in $(seq 1 191); do \
    docker run -e IPRANGE="$i.0.0.0/8" geo-ip; \
    sleep 1; \ 
done

This prints less than 4,228,250,625 JSON lines to STDOUT. Here is an example of one of the lines:

{"city": "Palo Alto", "ip": "0.0.0.0", "longitude": -122.1274,
 "continent": "North America", "continent_code": "NA",
 "state": "California", "country": "United States", "latitude": 37.418,
 "iso_code": "US", "state_code": "CA", "aso": "PubNub",
 "asn": "11404", "zip_code": "94107"}

Private and Reserved IP Range

The dockerfile in the repo above will exclude non-usable IP addresses following the guide from the wikipedia article: https://en.wikipedia.org/wiki/Reserved_IP_addresses

MaxMind Geo IP

The dockerfile imports a free public Database provided by https://www.maxmind.com/en/home

I finally was able to modify butelo's code to open any PDF file in the Android filesystem using pdf.js. The code can be found on my GitHub

What I did was modified the pdffile.js to read HTML argument file like this:

var url = getURLParameter('file');

function getURLParameter(name) {
return decodeURIComponent((new RegExp('[?|&]' + name + '=' + '([^&;]+?)(&|#|;|$)').exec(location.search)||[,""])[1].replace(/\+/g, '%20'))||null}

So what you need to do is just append the file path after the index.html like this:

Uri path = Uri.parse(Environment.getExternalStorageDirectory().toString() + "/data/test.pdf");
webView.loadUrl("file:///android_asset/pdfviewer/index.html?file=" + path);

Update the path variable to point to a valid PDF in the Adroid filesystem.

Here is the solution I found on Hibernate 4.1.9. I had to pass a parameter to my query that can have value NULL sometimes. So I passed the using:

setParameter("orderItemId", orderItemId, new LongType())

After that, I use the following where clause in my query:

where ((:orderItemId is null) OR (orderItem.id != :orderItemId))

As you can see, I am using the Query.setParameter(String, Object, Type) method, where I couldn't use the Hibernate.LONG that I found in the documentation (probably that was on older versions). For a full set of options of type parameter, check the list of implementation class of org.hibernate.type.Type interface.

Hope this helps!

By using typecasting you can resolve your problem. Just add the following lines to your return object:

$arrObj = array(yourReturnedObject);

You can also add a new key and value pair to it by using:

$arrObj['key'] = value;

Spaces are used for separating Arguments. In your case C:\Program becomes argument. If your file path contains spaces then add Double quotation marks. Then cmd will recognize it as single argument.

Using jQuery, and assuming that you have <div id="foo">:

jQuery(function($){
  $('#foo').click(function(e){
    console.log( 'clicked on div' );
    e.stopPropagation(); // Prevent bubbling
  });
  $('body').click(function(e){
    console.log( 'clicked outside of div' );
  });
});

Edit: For a single handler:

jQuery(function($){
  $('body').click(function(e){
    var clickedOn = $(e.target);
    if (clickedOn.parents().andSelf().is('#foo')){
      console.log( "Clicked on", clickedOn[0], "inside the div" );
    }else{
      console.log( "Clicked outside the div" );
  });
});

Manual here says that you have to set server.error.whitelabel.enabled to false to disable the standard error page. Maybe it is what you want?

I am experiencing the same error after adding /error mapping, by the way.

If you have recently updated to ubuntu 14.04 here is the fix to this problem:

$ sudo mv /etc/php5/conf.d/mcrypt.ini /etc/php5/mods-available/
$ sudo php5enmod mcrypt
$ sudo service apache2 restart

If your calling code is referencing the System.Windows.Forms assembly, you may consider a radically different approach. My strategy is to use the functions already provided by the framework to accomplish this in very few lines of code and without having to loop through columns and rows. What the code below does is programmatically create a DataGridView on the fly and set the DataGridView.DataSource to the DataTable. Next, I programmatically select all the cells (including the header) in the DataGridView and call DataGridView.GetClipboardContent(), placing the results into the Windows Clipboard. Then, I 'paste' the contents of the clipboard into a call to File.WriteAllText(), making sure to specify the formatting of the 'paste' as TextDataFormat.CommaSeparatedValue.

Here is the code:

public static void DataTableToCSV(DataTable Table, string Filename)
{
    using(DataGridView dataGrid = new DataGridView())
    {
        // Save the current state of the clipboard so we can restore it after we are done
        IDataObject objectSave = Clipboard.GetDataObject();

        // Set the DataSource
        dataGrid.DataSource = Table;
        // Choose whether to write header. Use EnableWithoutHeaderText instead to omit header.
        dataGrid.ClipboardCopyMode = DataGridViewClipboardCopyMode.EnableAlwaysIncludeHeaderText;
        // Select all the cells
        dataGrid.SelectAll();
        // Copy (set clipboard)
        Clipboard.SetDataObject(dataGrid.GetClipboardContent());
        // Paste (get the clipboard and serialize it to a file)
        File.WriteAllText(Filename,Clipboard.GetText(TextDataFormat.CommaSeparatedValue));              

        // Restore the current state of the clipboard so the effect is seamless
        if(objectSave != null) // If we try to set the Clipboard to an object that is null, it will throw...
        {
            Clipboard.SetDataObject(objectSave);
        }
    }
}

Notice I also make sure to preserve the contents of the clipboard before I begin, and restore it once I'm done, so the user does not get a bunch of unexpected garbage next time the user tries to paste. The main caveats to this approach is 1) Your class has to reference System.Windows.Forms, which may not be the case in a data abstraction layer, 2) Your assembly will have to be targeted for .NET 4.5 framework, as DataGridView does not exist in 4.0, and 3) The method will fail if the clipboard is being used by another process.

Anyways, this approach may not be right for your situation, but it is interesting none the less, and can be another tool in your toolbox.

1. $page='one' should occur before you require_once() not after. After is too late- the code has already been required, and $nav has already been defined.

2. You should use include('header.php'); and include('footer.php'); instead of setting a $nav variable early on. That increases flexibility.

3. Make more functions. Something like this really makes things easier to follow:

   function maybe($x,$y){return $x?$y:'';}
   function aclass($k){return " class=\"$k\" "; }
   

   then you can write your "condition" like this:

   <a href="..." <?= maybe($page=='one',aclass('active')) ?>> ....

Add a comma between the ip and port

Let arrList be the ArrayList and newValue the new String, then just do:

arrList.set(5, newValue);

This can be found in the java api reference here.

Based on above answers I created the following API

/*
 * .addClassSVG(className)
 * Adds the specified class(es) to each of the set of matched SVG elements.
 */
$.fn.addClassSVG = function(className){
    $(this).attr('class', function(index, existingClassNames) {
        return ((existingClassNames !== undefined) ? (existingClassNames + ' ') : '') + className;
    });
    return this;
};

/*
 * .removeClassSVG(className)
 * Removes the specified class to each of the set of matched SVG elements.
 */
$.fn.removeClassSVG = function(className){
    $(this).attr('class', function(index, existingClassNames) {
        var re = new RegExp('\\b' + className + '\\b', 'g');
        return existingClassNames.replace(re, '');
    });
    return this;
};

You propably have to write some JavaScript, because there is no way to estimate the height of all the users of the page.

In the Coursera course, an Introduction to R Programming, this skill was tested. They gave all the students 332 separate csv files and asked them to programmatically combined several of the files to calculate the mean value of the pollutant.

This was my solution:

  # create your empty dataframe so you can append to it.
  combined_df <- data.frame(Date=as.Date(character()),
                    Sulfate=double(),
                    Nitrate=double(),
                    ID=integer())
  # for loop for the range of documents to combine
  for(i in min(id): max(id)) {
    # using sprintf to add on leading zeros as the file names had leading zeros
    read <- read.csv(paste(getwd(),"/",directory, "/",sprintf("%03d", i),".csv", sep=""))
    # in your loop, add the files that you read to the combined_df
    combined_df <- rbind(combined_df, read)
  }

To renew the development profile before it expired, I finally found a way that works for me. I boldfaced the steps I had been missing before.

Go to the Apple provisioning portal, select "Provisioning". You'll get a list "Development Provisioning Profiles" where you'll see your soon to expire profile with the label "Managed by XCode". Click the "New Profile" button on top, select the type of profile you want and create it. Wait half a minute, refresh the home screen and when it shows the new profile as "Active", switch back to XCode, go to the Organizer, select "Provisioning profiles" under "Library" in left top column. Click "Refresh" at the bottom, log in (if it asks) and the new profile appears in the list after a short while.

Now, crucially, connect your device and drag your new profile to the "Provisioning Profiles" row under the connected device in the left column.

Finally, you can clean up the old profiles from your device if you feel like it.

Note: interestingly, it seems that simply marking and deleting your provisioning profile on the iOS Provisioning Portal site causes a new fresh Team Provisioning Profile to be created. So maybe that is all that is needed. I will try that next time to see if that is enough, if so you don't need to create a profile as I described above.

This site might help you out with all of that:

pushing commits, whether empty or not, causes eventual git hooks to be triggered. This can do either nothing or have world shattering consequences.

If you want to enable unblur, you cannot just add the blur CSS to the body, you need to blur each visible child one level directly under the body and then remove the CSS to unblur. The reason is because of the "Cascade" in CSS, you cannot undo the cascading of the CSS blur effect for a child of the body. Also, to blur the body's background image you need to use the pseudo element :before

I recommend you to generate an open format XML Excel file, is much more flexible than CSV.
Read Generating an Excel file in ASP.NET for more info

Also consider that if you click a button, the target of the event listener is not necessaily the button itself, but whatever content inside the button you clicked on. You can reference the element to which you assigned the listener using the currentTarget property. Here is a pretty solution in modern ES using a single statement:

    document.querySelectorAll(".myClassName").forEach(i => i.addEventListener(
        "click",
        e => {
            alert(e.currentTarget.dataset.myDataContent);
        }));

Two corrections:

1. You have to make an ArrayList of People objects:

   ArrayList<People> preps = new ArrayList<People>(); 
   

2. After adding the objects to the preps, use:

   Collections.sort(preps, new CompareId());
   

Also, add a CompareId class as:

class CompareId implements Comparator {  
    public int compare(Object obj1, Object obj2) {  
        People t1 = (People)obj1;  
        People t2 = (People)obj2;  

        if (t1.marks > t2.marks)  
            return 1;   
        else  
            return -1;
    }  
}

I just found a really messed up case.

moment('Decimal128', 'YYYY-MM-DD').isValid() // true

1. Connection pooling is handled as in any other ADO.NET application. Entity connection still uses traditional database connection with traditional connection string. I believe you can turn off connnection pooling in connection string if you don't want to use it. (read more about SQL Server Connection Pooling (ADO.NET))
2. Never ever use global context. ObjectContext internally implements several patterns including Identity Map and Unit of Work. Impact of using global context is different per application type.
3. For web applications use single context per request. For web services use single context per call. In WinForms or WPF application use single context per form or per presenter. There can be some special requirements which will not allow to use this approach but in most situation this is enough.

If you want to know what impact has single object context for WPF / WinForm application check this article. It is about NHibernate Session but the idea is same.

Edit:

When you use EF it by default loads each entity only once per context. The first query creates entity instace and stores it internally. Any subsequent query which requires entity with the same key returns this stored instance. If values in the data store changed you still receive the entity with values from the initial query. This is called Identity map pattern. You can force the object context to reload the entity but it will reload a single shared instance.

Any changes made to the entity are not persisted until you call SaveChanges on the context. You can do changes in multiple entities and store them at once. This is called Unit of Work pattern. You can't selectively say which modified attached entity you want to save.

Combine these two patterns and you will see some interesting effects. You have only one instance of entity for the whole application. Any changes to the entity affect the whole application even if changes are not yet persisted (commited). In the most times this is not what you want. Suppose that you have an edit form in WPF application. You are working with the entity and you decice to cancel complex editation (changing values, adding related entities, removing other related entities, etc.). But the entity is already modified in shared context. What will you do? Hint: I don't know about any CancelChanges or UndoChanges on ObjectContext.

I think we don't have to discuss server scenario. Simply sharing single entity among multiple HTTP requests or Web service calls makes your application useless. Any request can just trigger SaveChanges and save partial data from another request because you are sharing single unit of work among all of them. This will also have another problem - context and any manipulation with entities in the context or a database connection used by the context is not thread safe.

Even for a readonly application a global context is not a good choice because you probably want fresh data each time you query the application.

Gradle 4.9+

gradle run --args='arg1 arg2'

This assumes your build.gradle is configured with the Application plugin. Your build.gradle should look similar to this:

plugins {
  // Implicitly applies Java plugin
  id: 'application'
}

application {
  // URI of your main class/application's entry point (required)
  mainClassName = 'org.gradle.sample.Main'
}

Pre-Gradle 4.9

Include the following in your build.gradle:

run {
    if (project.hasProperty("appArgs")) {
        args Eval.me(appArgs)
    }
}

Then to run: gradle run -PappArgs="['arg1', 'args2']"

SHA-1 produces a 160-bit message (20 bytes), too large to be stored in an int or long value. As Ralph suggests, you could use BigInteger.

To get a (less-secure) int hash, you could return the hash code of the returned byte array.

Alternatively, if you don't really need SHA at all, you could just use the UUID's String hash code.

@PathVariable used to fetch the value from URL

for example: To get some question

www.stackoverflow.com/questions/19803731

Here some question id is passed as a parameter in URL

Now to fetch this value in controller all you have to do is just to pass @PathVariable in the method parameter

@RequestMapping(value = " /questions/{questionId}", method=RequestMethod.GET)
    public String getQuestion(@PathVariable String questionId){
    //return question details
}

I don't see an obvious problem with the above.

It's possible your ldap.conf is being overridden, but the command-line options will take precedence, ldapsearch will ignore BINDDN in the main ldap.conf, so the only parameter that could be wrong is the URI. (The order is ETCDIR/ldap.conf then ~/ldaprc or ~/.ldaprc and then ldaprc in the current directory, though there environment variables which can influence this too, see man ldapconf.)

Try an explicit URI:

ldapsearch -x -W -D 'cn=Manager,dc=example,dc=com' -b "" -s base -H ldap://localhost

or prevent defaults with:

LDAPNOINIT=1 ldapsearch -x -W -D 'cn=Manager,dc=example,dc=com' -b "" -s base

If that doesn't work, then some troubleshooting (you'll probably need the full path to the slapd binary for these):

• make sure your slapd.conf is being used and is correct (as root)

  slapd -T test -f slapd.conf -d 65535

  You may have a left-over or default slapd.d configuration directory which takes preference over your slapd.conf (unless you specify your config explicitly with -f, slapd.conf is officially deprecated in OpenLDAP-2.4). If you don't get several pages of output then your binaries were built without debug support.

• stop OpenLDAP, then manually start slapd in a separate terminal/console with debug enabled (as root, ^C to quit)

  slapd -h ldap://localhost -d 481

  then retry the search and see if you can spot the problem (there will be a lot of schema noise in the start of the output unfortunately). (Note: running slapd without the -u/-g options can change file ownerships which can cause problems, you should usually use those options, probably -u ldap -g ldap )

• if debug is enabled, then try also

  ldapsearch -v -d 63 -W -D 'cn=Manager,dc=example,dc=com' -b "" -s base

this solved it npm cache clean --force

No internal means, AFAIK. Use this: memset(c, 0, length);

Thats because DataGridView looks for properties of containing objects. For string there is just one property - length. So, you need a wrapper for a string like this

public class StringValue
{
    public StringValue(string s)
    {
        _value = s;
    }
    public string Value { get { return _value; } set { _value = value; } }
    string _value;
}

Then bind List<StringValue> object to your grid. It works

Here is a complete solution which incorporates the best answer and the comments below it (which might help someone struggling to piece it all together):

UPDATE FOR ES6 (2019) - using arrow functions and object destructuring

in main component:

class ReactMain extends React.Component {

  constructor(props) {
    super(props);
    this.state = { fruit: props.item.fruit };
  }

  handleChange = (event) => {
    this.setState({ [event.target.name]: event.target.value });
  }

  saveItem = () => {
    const item = {};
    item.fruit = this.state.fruit;
    // do more with item object as required (e.g. save to database)
  }

  render() {
    return (
      <ReactExample name="fruit" value={this.state.fruit} handleChange={this.handleChange} />
    )
  }

}

included component (which is now a stateless functional):

export const ReactExample = ({ name, value, handleChange }) => (
  <select name={name} value={value} onChange={handleChange}>
    <option value="A">Apple</option>
    <option value="B">Banana</option>
    <option value="C">Cranberry</option>
  </select>
)

PREVIOUS ANSWER (using bind):

in main component:

class ReactMain extends React.Component {

  constructor(props) {
    super(props);
    // bind once here, better than multiple times in render
    this.handleChange = this.handleChange.bind(this);
    this.state = { fruit: props.item.fruit };
  }

  handleChange(event) {
    this.setState({ [event.target.name]: event.target.value });
  }

  saveItem() {
    const item = {};
    item.fruit = this.state.fruit;
    // do more with item object as required (e.g. save to database)
  }

  render() {
    return (
      <ReactExample name="fruit" value={this.state.fruit} handleChange={this.handleChange} />
    )
  }

}

included component (which is now a stateless functional):

export const ReactExample = (props) => (
  <select name={props.name} value={props.value} onChange={props.handleChange}>
    <option value="A">Apple</option>
    <option value="B">Banana</option>
    <option value="C">Cranberry</option>
  </select>
)

the main component maintains the selected value for fruit (in state), the included component displays the select element and updates are passed back to the main component to update its state (which then loops back to the included component to change the selected value).

Note the use of a name prop which allows you to declare a single handleChange method for other fields on the same form regardless of their type.

Quoting http://php.net/manual/en/intro.mssql.php:

The MSSQL extension is not available anymore on Windows with PHP 5.3 or later. SQLSRV, an alternative driver for MS SQL is available from Microsoft: » http://msdn.microsoft.com/en-us/sqlserver/ff657782.aspx.

Once you downloaded that, follow the instructions at this page:

• Loading the Microsoft Drivers for PHP for SQL Server

In a nutshell:

Put the driver file in your PHP extension directory.
Modify the php.ini file to include the driver. For example:

extension=php_sqlsrv_53_nts_vc9.dll  

Restart the Web server.

See Also (copied from that page)

• System Requirements (Microsoft Drivers for PHP for SQL Server)
• Getting Started
• Programming Guide
• SQLSRV Driver API Reference (Microsoft Drivers for PHP for SQL Server)

The PHP Manual for the SQLSRV extension is located at http://php.net/manual/en/sqlsrv.installation.php and offers the following for Installation:

The SQLSRV extension is enabled by adding appropriate DLL file to your PHP extension directory and the corresponding entry to the php.ini file. The SQLSRV download comes with several driver files. Which driver file you use will depend on 3 factors: the PHP version you are using, whether you are using thread-safe or non-thread-safe PHP, and whether your PHP installation was compiled with the VC6 or VC9 compiler. For example, if you are running PHP 5.3, you are using non-thread-safe PHP, and your PHP installation was compiled with the VC9 compiler, you should use the php_sqlsrv_53_nts_vc9.dll file. (You should use a non-thread-safe version compiled with the VC9 compiler if you are using IIS as your web server). If you are running PHP 5.2, you are using thread-safe PHP, and your PHP installation was compiled with the VC6 compiler, you should use the php_sqlsrv_52_ts_vc6.dll file.

The drivers can also be used with PDO.

A somewhat unlikely situation.

I have removed the yarn.lock file, which referenced an older version of webpack.

So check to see the differences in your yarn.lock file as a possiblity.

The same notation is used for pointing at a single character or the first character of a null-terminated string:

char c = 'Z';
char a[] = "Hello world";

char *ptr1 = &c;
char *ptr2 = a;      // Points to the 'H' of "Hello world"
char *ptr3 = &a[0];  // Also points to the 'H' of "Hello world"
char *ptr4 = &a[6];  // Points to the 'w' of "world"
char *ptr5 = a + 6;  // Also points to the 'w' of "world"

The values in ptr2 and ptr3 are the same; so are the values in ptr4 and ptr5. If you're going to treat some data as a string, it is important to make sure it is null terminated, and that you know how much space there is for you to use. Many problems are caused by not understanding what space is available and not knowing whether the string was properly null terminated.

Note that all the pointers above can be dereferenced as if they were an array:

 *ptr1    == 'Z'
  ptr1[0] == 'Z'

 *ptr2    == 'H'
  ptr2[0] == 'H'
  ptr2[4] == 'o'

 *ptr4    == 'w'
  ptr4[0] == 'w'
  ptr4[4] == 'd'

  ptr5[0] ==   ptr3[6]
*(ptr5+0) == *(ptr3+6)

Late addition to question

What does char (*ptr)[N]; represent?

This is a more complex beastie altogether. It is a pointer to an array of N characters. The type is quite different; the way it is used is quite different; the size of the object pointed to is quite different.

char (*ptr)[12] = &a;

(*ptr)[0] == 'H'
(*ptr)[6] == 'w'

*(*ptr + 6) == 'w'

Note that ptr + 1 points to undefined territory, but points 'one array of 12 bytes' beyond the start of a. Given a slightly different scenario:

char b[3][12] = { "Hello world", "Farewell", "Au revoir" };

char (*pb)[12] = &b[0];

Now:

(*(pb+0))[0] == 'H'
(*(pb+1))[0] == 'F'
(*(pb+2))[5] == 'v'

You probably won't come across pointers to arrays except by accident for quite some time; I've used them a few times in the last 25 years, but so few that I can count the occasions on the fingers of one hand (and several of those have been answering questions on Stack Overflow). Beyond knowing that they exist, that they are the result of taking the address of an array, and that you probably didn't want it, you don't really need to know more about pointers to arrays.

You could right click on those cells, go to format, select custom, then type mm yyyy.

Do you need the pipe?

echo -ne "$MENU"
read NUMBER

Two solutions 1. use merge if you want to update the object 2. use save if you want to just save new object (make sure identity is null to let hibernate or database generate it) 3. if you are using mapping like
@OneToOne(fetch = FetchType.EAGER,cascade=CascadeType.ALL) @JoinColumn(name = "stock_id")

Then use CascadeType.ALL to CascadeType.MERGE

In the closure you pass to sort, compare the properties you want to sort by. Like this:

movieArr.sorted { $0.name < $1.name }

or the following in the cases that you want to bypass cases:

movieArr.sorted { $0.name.lowercased() < $1.name.lowercased() }

Sidenote: Typically only types start with an uppercase letter; I'd recommend using name and date, not Name and Date.

Example, in a playground:

class Movie {
    let name: String
    var date: Int?

    init(_ name: String) {
        self.name = name
    }
}

var movieA = Movie("A")
var movieB = Movie("B")
var movieC = Movie("C")

let movies = [movieB, movieC, movieA]
let sortedMovies = movies.sorted { $0.name < $1.name }
sortedMovies

sortedMovies will be in the order [movieA, movieB, movieC]

Swift5 Update

channelsArray = channelsArray.sorted { (channel1, channel2) -> Bool in
            let channelName1 = channel1.name
            let channelName2 = channel2.name
            return (channelName1.localizedCaseInsensitiveCompare(channelName2) == .orderedAscending)

There's also an option to Auto Sync built-in in Aptana.

I am using the new EF & Identity Core and I have the same issue, with the addition that I've got this error:

The instance of entity type cannot be tracked because another instance of this type with the same key is already being tracked.

With the new DI model I added the constructor's Controller the context to the DB.

I tried to see what are the conflict with _conext.ChangeTracker.Entries() and adding AsNoTracking() to my calls without success.

I only need to change the state of my object (in this case Identity)

_context.Entry(user).State = EntityState.Modified;
var result = await _userManager.UpdateAsync(user);

And worked without create another store or object and mapping.

I hope someone else is useful my two cents.

You can do like this.

webView = (WebView) findViewById(R.id.webView1);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("Your URL goes here");

Inside catalina.bat set the port on which you wish to start the debugger

if not "%JPDA_ADDRESS%" == "" goto gotJpdaAddress
set JPDA_ADDRESS=9001

Then you can simply start the debugger with

catalina.bat jpda 

Now from Eclipse or IDEA select remote debugging and start start debugging by connecting to port 9001.

I usually use sys.platform (docs) to get the platform. sys.platform will distinguish between linux, other unixes, and OS X, while os.name is "posix" for all of them.

For much more detailed information, use the platform module. This has cross-platform functions that will give you information on the machine architecture, OS and OS version, version of Python, etc. Also it has os-specific functions to get things like the particular linux distribution.

For a CSS-only (and icon-free) solution using Bootstrap 3 I had to do a bit of fiddling based on Martin Wickman's answer above.

I didn't use the accordion-* notation because it's done with panels in BS3.

Also, I had to include in the initial HTML aria-expanded="true" on the item that's open at page load.

Here is the CSS I used.

.accordion-toggle:hover { text-decoration: none; }
.accordion-toggle:hover span, .accordion-toggle:hover strong { text-decoration: underline; }
.accordion-toggle:before { font-size: 25px; }
.accordion-toggle[data-toggle="collapse"]:before { content: "+"; margin-right: 0px; }
.accordion-toggle[aria-expanded="true"]:before { content: "-"; margin-right: 0px; }

Here is my sanitized HTML:

<div id="acc1">    
    <div class="panel panel-default">
        <div class="panel-heading">
            <span class="panel-title">
                <a class="accordion-toggle" data-toggle="collapse" aria-expanded="true" data-parent="#acc1" href="#acc1-1">Title 1
                    </a>
            </span>
        </div>
        <div id=“acc1-1” class="panel-collapse collapse in">
            <div class="panel-body">
                Text 1
            </div>
        </div>
    </div>
    <div class="panel panel-default">
        <div class="panel-heading">
            <span class="panel-title">
                <a class="accordion-toggle" data-toggle="collapse" data-parent="#acc1” href=“#acc1-2”>Title 2
                    </a>
            </span>
        </div>
        <div id=“acc1-2” class="panel-collapse collapse">
            <div class="panel-body">
                Text 2                  
            </div>
        </div>
    </div>
</div>

After fiddling around for a while, I figured things out, and am posting them here hoping it will help others.

Intuitively, np.where is like asking "tell me where in this array, entries satisfy a given condition".

>>> a = np.arange(5,10)
>>> np.where(a < 8)       # tell me where in a, entries are < 8
(array([0, 1, 2]),)       # answer: entries indexed by 0, 1, 2

It can also be used to get entries in array that satisfy the condition:

>>> a[np.where(a < 8)] 
array([5, 6, 7])          # selects from a entries 0, 1, 2

When a is a 2d array, np.where() returns an array of row idx's, and an array of col idx's:

>>> a = np.arange(4,10).reshape(2,3)
array([[4, 5, 6],
       [7, 8, 9]])
>>> np.where(a > 8)
(array(1), array(2))

As in the 1d case, we can use np.where() to get entries in the 2d array that satisfy the condition:

>>> a[np.where(a > 8)] # selects from a entries 0, 1, 2

array([9])

Note, when a is 1d, np.where() still returns an array of row idx's and an array of col idx's, but columns are of length 1, so latter is empty array.

There is a simple hack, use $_SESSION and create an array of the posted values, and once you go to the File_C.php you can use it then do you process after that destroy it.

Can't stand aside,

So we have linear system:

A₁ * x + B₁ * y = C₁
A₂ * x + B₂ * y = C₂

let's do it with Cramer's rule, so solution can be found in determinants:

x = D_x/D
y = D_y/D

where D is main determinant of the system:

A₁ B₁
A₂ B₂

and D_x and D_y can be found from matricies:

C₁ B₁
C₂ B₂

and

A₁ C₁
A₂ C₂

(notice, as C column consequently substitues the coef. columns of x and y)

So now the python, for clarity for us, to not mess things up let's do mapping between math and python. We will use array L for storing our coefs A, B, C of the line equations and intestead of pretty x, y we'll have [0], [1], but anyway. Thus, what I wrote above will have the following form further in the code:

for D

L1[0] L1[1]
L2[0] L2[1]

for D_x

L1[2] L1[1]
L2[2] L2[1]

for D_y

L1[0] L1[2]
L2[0] L2[2]

Now go for coding:

line - produces coefs A, B, C of line equation by two points provided,
intersection - finds intersection point (if any) of two lines provided by coefs.

from __future__ import division 

def line(p1, p2):
    A = (p1[1] - p2[1])
    B = (p2[0] - p1[0])
    C = (p1[0]*p2[1] - p2[0]*p1[1])
    return A, B, -C

def intersection(L1, L2):
    D  = L1[0] * L2[1] - L1[1] * L2[0]
    Dx = L1[2] * L2[1] - L1[1] * L2[2]
    Dy = L1[0] * L2[2] - L1[2] * L2[0]
    if D != 0:
        x = Dx / D
        y = Dy / D
        return x,y
    else:
        return False

Usage example:

L1 = line([0,1], [2,3])
L2 = line([2,3], [0,4])

R = intersection(L1, L2)
if R:
    print "Intersection detected:", R
else:
    print "No single intersection point detected"

Use subquery

SELECT * FROM RES_DATA inner join (SELECT [CUSTOMER ID], sum([TOTAL AMOUNT]) FROM INV_DATA group by [CUSTOMER ID]) T on RES_DATA.[CUSTOMER ID] = t.[CUSTOMER ID]

md5=$(md5sum < $file | tr -d ' -')

Put all the commands on to a script and it can be run like

ssh <remote-user>@<remote-host> "bash -s" <./remote-commands.sh

A property, when it has no definition, is undefined. null is an object. It's type is null. undefined is not an object, its type is undefined.

This is a good article explaining the difference and also giving some examples.

null vs undefined

I know this question is a few years old, but as Java 8 has, in the meantime, brought us Optional, I thought I'd offer up a solution using it (and Stream and Collectors):

public enum PcapLinkType {
  DLT_NULL(0),
  DLT_EN3MB(2),
  DLT_AX25(3),
  /*snip, 200 more enums, not always consecutive.*/
  // DLT_UNKNOWN(-1); // <--- NO LONGER NEEDED

  private final int value;
  private PcapLinkType(int value) { this.value = value; }

  private static final Map<Integer, PcapLinkType> map;
  static {
    map = Arrays.stream(values())
        .collect(Collectors.toMap(e -> e.value, e -> e));
  }

  public static Optional<PcapLinkType> fromInt(int value) {
    return Optional.ofNullable(map.get(value));
  }
}

Optional is like null: it represents a case when there is no (valid) value. But it is a more type-safe alternative to null or a default value such as DLT_UNKNOWN because you could forget to check for the null or DLT_UNKNOWN cases. They are both valid PcapLinkType values! In contrast, you cannot assign an Optional<PcapLinkType> value to a variable of type PcapLinkType. Optional makes you check for a valid value first.

Of course, if you want to retain DLT_UNKNOWN for backward compatibility or whatever other reason, you can still use Optional even in that case, using orElse() to specify it as the default value:

public enum PcapLinkType {
  DLT_NULL(0),
  DLT_EN3MB(2),
  DLT_AX25(3),
  /*snip, 200 more enums, not always consecutive.*/
  DLT_UNKNOWN(-1);

  private final int value;
  private PcapLinkType(int value) { this.value = value; }

  private static final Map<Integer, PcapLinkType> map;
  static {
    map = Arrays.stream(values())
        .collect(Collectors.toMap(e -> e.value, e -> e));
  }

  public static PcapLinkType fromInt(int value) {
    return Optional.ofNullable(map.get(value)).orElse(DLT_UNKNOWN);
  }
}

With Java 9, Java 8u161, Java 7u171 and Java 6u181 the limitation is now disabled by default. See issue in Java Bug Database.

Beginning with Java 8u151 you can disable the limitation programmatically.

In older releases, JCE jurisdiction files had to be downloaded and installed separately to allow unlimited cryptography to be used by the JDK. The download and install steps are no longer necessary.

Instead you can now invoke the following line before first use of JCE classes (i.e. preferably right after application start):

Security.setProperty("crypto.policy", "unlimited");

This is the best solution (simplest) above everything I have tried.

...And this does not keep the native experience of the address bar!

You could set the height with CSS to 100% for example, and then set the height to 0.9 * of the window height in px with javascript, when the document is loaded.

For example with jQuery:

$("#element").css("height", 0.9*$(window).height());

)

Unfortunately there isn't anything that works with pure CSS :P but also be minfull that vh and vw are buggy on iPhones - use percentages.

tolomea's answer worked for me. I hacked it into socketserver.UDPServer too:

class ThreadedMulticastServer(socketserver.ThreadingMixIn, socketserver.UDPServer):
    def __init__(self, *args):
        super().__init__(*args)
        self.socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, socket.IPPROTO_UDP)
        self.socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
        self.socket.bind((MCAST_GRP, MCAST_PORT))
        mreq = struct.pack('4sl', socket.inet_aton(MCAST_GRP), socket.INADDR_ANY)
        self.socket.setsockopt(socket.IPPROTO_IP, socket.IP_ADD_MEMBERSHIP, mreq)

Performance-wise it's the same as a named method. The big problem is when you do the following:

MyButton.Click -= (o, i) => 
{ 
    //snip 
} 

It will probably try to remove a different lambda, leaving the original one there. So the lesson is that it's fine unless you also want to be able to remove the handler.

The main difference is ::

npm install is a npm cli-command which does the predefined thing i.e, as written by Churro, to install dependencies specified inside package.json

npm run command-name or npm run-script command-name ( ex. npm run build ) is also a cli-command predefined to run your custom scripts with the name specified in place of "command-name". So, in this case npm run build is a custom script command with the name "build" and will do anything specified inside it (for instance echo 'hello world' given in below example package.json).

Ponits to note::

1. One more thing, npm build and npm run build are two different things, npm run build will do custom work written inside package.json and npm build is a pre-defined script (not available to use directly)

2. You cannot specify some thing inside custom build script (npm run build) script and expect npm build to do the same. Try following thing to verify in your package.json:

   { "name": "demo", "version": "1.0.0", "description": "", "main": "index.js", "scripts": { "build":"echo 'hello build'" }, "keywords": [], "author": "", "license": "ISC", "devDependencies": {}, "dependencies": {} }

and run npm run build and npm build one by one and you will see the difference. For more about commands kindly follow npm documentation.

Cheers!!

For read a cookie i've made little modifications of the Miquel version that doesn't work for me:

getCookie(name: string) {
        let ca: Array<string> = document.cookie.split(';');
        let cookieName = name + "=";
        let c: string;

        for (let i: number = 0; i < ca.length; i += 1) {
            if (ca[i].indexOf(name, 0) > -1) {
                c = ca[i].substring(cookieName.length +1, ca[i].length);
                console.log("valore cookie: " + c);
                return c;
            }
        }
        return "";

I was also developing a similar application. I was also getting not found error even though the file was there. This solve my problem. I mention my download folder in 'static_folder':

app = Flask(__name__,static_folder='pdf')

My code for the download is as follows:

@app.route('/pdf/<path:filename>', methods=['GET', 'POST'])
def download(filename):    
    return send_from_directory(directory='pdf', filename=filename)

This is how I am calling my file from html.

<a class="label label-primary" href=/pdf/{{  post.hashVal }}.pdf target="_blank"  style="margin-right: 5px;">Download pdf </a>
<a class="label label-primary" href=/pdf/{{  post.hashVal }}.png target="_blank"  style="margin-right: 5px;">Download png </a>

You can also use external configuration file to specify connection strings section, and refer that file in application configuration file like in web.config

Like the in web.config file:

<configuration>  
    <connectionStrings configSource="connections.config"/>  
</configuration>  

The external configuration connections.config file will contains connections section

<connectionStrings>  
  <add name="Name"   
   providerName="System.Data.ProviderName"   
   connectionString="Valid Connection String;" />  

</connectionStrings>  

Modifying contents of external configuration file will not restart the application (as ASP.net does by default with any change in application configuration files)

Easy peasy with re.sub regular expression as of Python 3.5

re.sub('\ |\?|\.|\!|\/|\;|\:', '', line)

Example

>>> import re

>>> line = 'Q: Do I write ;/.??? No!!!'

>>> re.sub('\ |\?|\.|\!|\/|\;|\:', '', line)
'QDoIwriteNo'

Explanation

In regular expressions (regex), | is a logical OR and \ escapes spaces and special characters that might be actual regex commands. Whereas sub stands for substitution, in this case with the empty string ''.

An inline-block covers the whole line (from left to right), so a margin left and/or right won't work here. What you need is a block, a block has borders on the left and the right so can be influenced by margins.

This is how it works for me:

#content {
display: block;
margin: 0 auto;
}

Simple code for underscore.py package fan

from underscore import _
_.flatten([[1, 2, 3], [4, 5, 6], [7], [8, 9]])
# [1, 2, 3, 4, 5, 6, 7, 8, 9]

It solves all flatten problems (none list item or complex nesting)

from underscore import _
# 1 is none list item
# [2, [3]] is complex nesting
_.flatten([1, [2, [3]], [4, 5, 6], [7], [8, 9]])
# [1, 2, 3, 4, 5, 6, 7, 8, 9]

You can install underscore.py with pip

pip install underscore.py

I took @hajamie's solution and wrapped it up into a slightly more convenient script wrapper.

I added an option to start from an offset before the end of the file, so you can use the tail-like functionality of reading a certain amount from the end of the file. Note the offset is in bytes, not lines.

There's also an option to continue waiting for more content.

Examples (assuming you save this as TailFile.ps1):

.\TailFile.ps1 -File .\path\to\myfile.log -InitialOffset 1000000
.\TailFile.ps1 -File .\path\to\myfile.log -InitialOffset 1000000 -Follow:$true
.\TailFile.ps1 -File .\path\to\myfile.log -Follow:$true

And here is the script itself...

param (
    [Parameter(Mandatory=$true,HelpMessage="Enter the path to a file to tail")][string]$File = "",
    [Parameter(Mandatory=$true,HelpMessage="Enter the number of bytes from the end of the file")][int]$InitialOffset = 10248,
    [Parameter(Mandatory=$false,HelpMessage="Continuing monitoring the file for new additions?")][boolean]$Follow = $false
)

Another workaround would be to make use of prettier to format the JSON. The example below is using 'json' parser but it could also use 'json5', see list of valid parsers.

const prettier = require("prettier");
console.log(prettier.format(JSON.stringify(object),{ semi: false, parser: "json" }));

(I just got this working, with my main issue being that I don't have a real internet hostname, so answering this question in case it helps someone)

You need to specify a hostname with HELO. Even so, you should get an error, so Postfix is probably not running.

Also, the => is not a command. The '.' on a single line without any text around it is what tells Postfix that the entry is complete. Here are the entries I used:

telnet localhost 25
(says connected)
EHLO howdy.com
(returns a bunch of 250 codes)
MAIL FROM: [email protected]
RCPT TO: (use a real email address you want to send to)
DATA (type whatever you want on muliple lines)
. (this on a single line tells Postfix that the DATA is complete)

You should get a response like:

250 2.0.0 Ok: queued as 6E414C4643A

The email will probably end up in a junk folder. If it is not showing up, then you probably need to setup the 'Postfix on hosts without a real Internet hostname'. Here is the breakdown on how I completed that step on my Ubuntu box:

sudo vim /etc/postfix/main.cf
smtp_generic_maps = hash:/etc/postfix/generic (add this line somewhere)
(edit or create the file 'generic' if it doesn't exist)
sudo vim /etc/postfix/generic
(add these lines, I don't think it matters what names you use, at least to test)
[email protected]             [email protected]
[email protected]             [email protected]
@localdomain.local                [email protected]
then run:
postmap /etc/postfix/generic (this needs to be run whenever you change the 
generic file)

Happy Trails

After you use WhenAll, you can pull the results out individually with await:

var catTask = FeedCat();
var houseTask = SellHouse();
var carTask = BuyCar();

await Task.WhenAll(catTask, houseTask, carTask);

var cat = await catTask;
var house = await houseTask;
var car = await carTask;

You can also use Task.Result (since you know by this point they have all completed successfully). However, I recommend using await because it's clearly correct, while Result can cause problems in other scenarios.

no double quotes no parentheses.

Submodule repositories stay in a detached HEAD state pointing to a specific commit. Changing that commit simply involves checking out a different tag or commit then adding the change to the parent repository.

$ cd submodule
$ git checkout v2.0
Previous HEAD position was 5c1277e... bumped version to 2.0.5
HEAD is now at f0a0036... version 2.0

git-status on the parent repository will now report a dirty tree:

# On branch dev [...]
#
#   modified:   submodule (new commits)

Add the submodule directory and commit to store the new pointer.

Another option is :

View  >  Quick Switch Scheme  >  Keymap  >  Eclipse

Your problem is that the indices returned by match.start() correspond to the position of the character as it appeared in the original string when you matched it; however, as you rewrite the string c every time, these indices become incorrect.

The best approach to solve this is to use replaceAll, for example:

        System.out.println(c.replaceAll("[^a-zA-Z0-9]", ""));

I encountered this problem when I accidentally tried running my python module through the command prompt while my working directory was C:\Windows\System32 instead of the usual directory from which I run my python module

Do this

...
var el = document.getElementById('targetFrame');

var frame_win = getIframeWindow(el);

console.log(frame_win);
...

getIframeWindow is defined here

function getIframeWindow(iframe_object) {
  var doc;

  if (iframe_object.contentWindow) {
    return iframe_object.contentWindow;
  }

  if (iframe_object.window) {
    return iframe_object.window;
  } 

  if (!doc && iframe_object.contentDocument) {
    doc = iframe_object.contentDocument;
  } 

  if (!doc && iframe_object.document) {
    doc = iframe_object.document;
  }

  if (doc && doc.defaultView) {
   return doc.defaultView;
  }

  if (doc && doc.parentWindow) {
    return doc.parentWindow;
  }

  return undefined;
}

If you have to select the id:

 DELETE FROM table WHERE id IN (SELECT id FROM somewhere_else)

If you already know them (and they are not in the thousands):

 DELETE FROM table WHERE id IN (?,?,?,?,?,?,?,?)
