It sounds like you are using Visual Studio's Web Compiler extension. There is an open issue for this found here: https://github.com/madskristensen/WebCompiler/issues/413

There is a workaround posted in that issue:

1. Close Visual Studio
2. Head to C:\Users\USERNAME\AppData\Local\Temp\WebCompilerX.X.X (X is the version of WebCompiler)
3. Delete following folders from node_modules folder: caniuse-lite and browserslist Open up CMD (inside C:\Users\USERNAME\AppData\Local\Temp\WebCompilerX.X.X) and run: npm i caniuse-lite browserslist

I had this problem suddenly happening after trying to pull a dependency depending on sdk 28 (firebase crashlytics), but then decided to revert back the changes.

I tried automatic refactor Migrate to Androidx (which do half the job), added android.useAndroidX=true in gradle.properties at some points, and make the project work again.

But it was a lot of changes before a delivery. There was no way to have the project compile again with SDK 27. I git clean -fd, removed $HOME/.gradle, and kept seeing androidx in ./gradlew :app:dependencies

I ended up removing ~/.AndroidStudio3.5/ too (I'm on 3.5.3). This makes the project compile again, and I discovered the dark mode...

So I came to this question hoping for an answer but to no avail. I have used

const { history } = this.props;
history.push("/thePath")

In the same project and it worked as expected. Upon further experimentation and some comparing and contrasting, I realized that this code will not run if it is called within the nested component. Therefore only the rendered page component can call this function for it to work properly.

Just for others getting this error and looking for info on it, it is also thrown if you happen to pass a binding parameter and then never use it. I couldn't really find that stated clearly anywhere but had to prove it through trial and error.

My code was out of void setup() or void loop() in Arduino.

I would like to emphasize @icza answer and simplify it a bit since it is a crucial concept. I assume that reader is familiar with slices.

c := append(a, b...)

This is a valid answer to the question. BUT if you need to use slices 'a' and 'c' later in code in different context, this is not the safe way to concatenate slices.

To explain, lets read the expression not in terms of slices, but in terms of underlying arrays:

"Take (underlying) array of 'a' and append elements from array 'b' to it. If array 'a' has enough capacity to include all elements from 'b' - underlying array of 'c' will not be a new array, it will actually be array 'a'. Basically, slice 'a' will show len(a) elements of underlying array 'a', and slice 'c' will show len(c) of array 'a'."

append() does not necessarily create a new array! This can lead to unexpected results. See Go Playground example.

Always use make() function if you want to make sure that new array is allocated for the slice. For example here are few ugly but efficient enough options for the task.

la := len(a)
c := make([]int, la, la + len(b))
_ = copy(c, a)
c = append(c, b...)

la := len(a)
c := make([]int, la + len(b))
_ = copy(c, a)
_ = copy(c[la:], b)

My Solution

User.find()
        .exec()
        .then(users => {
            const response = {
                count: users.length,
                users: users.map(user => {

                    return {
                        _id: user._id,
                        // other property
                    }

                })

            };
            res.status(200).json(response);
        }).catch(err => {
        console.log(err);
        res.status(500).json({
            success: false
        })
    })

textarea.addEventListener("keypress", textareaLengthCheck(textarea), false);

You are calling textareaLengthCheck and then assigning its return value to the event listener. This is why it doesn't update or do anything after loading. Try this:

textarea.addEventListener("keypress",textareaLengthCheck,false);

Aside from that:

var length = textarea.length;

textarea is the actual textarea, not the value. Try this instead:

var length = textarea.value.length;

Combined with the previous suggestion, your function should be:

function textareaLengthCheck() {
    var length = this.value.length;
    // rest of code
};

SELECT a.C_ID,a.QRY_ID,a.RES_ID,b.SCORE,ROW_NUMBER() OVER (ORDER BY SCORE DESC) AS [RANK]
FROM CONTACTS a JOIN RSLTS b ON a.QRY_ID=b.QRY_ID AND a.RES_ID=b.RES_ID
ORDER BY a.C_ID

This jQuery function worked best for me. I'm using bootstrap 4 within a WordPress theme and I've used the full jQuery instead of jQuery slim.

// Set all carousel items to the same height
function carouselNormalization() {

    window.heights = [], //create empty array to store height values
    window.tallest; //create variable to make note of the tallest slide

    function normalizeHeights() {
        jQuery('#latest-blog-posts .carousel-item').each(function() { //add heights to array
            window.heights.push(jQuery(this).outerHeight());
        });
        window.tallest = Math.max.apply(null, window.heights); //cache largest value
        jQuery('#latest-blog-posts .carousel-item').each(function() {
            jQuery(this).css('min-height',tallest + 'px');
        });
    }
    normalizeHeights();

    jQuery(window).on('resize orientationchange', function () {

        window.tallest = 0, window.heights.length = 0; //reset vars
        jQuery('.sc_slides .item').each(function() {
            jQuery(this).css('min-height','0'); //reset min-height
        }); 

        normalizeHeights(); //run it again 

    });

}

jQuery( document ).ready(function() {
    carouselNormalization();
});

I faced this issue, and resolved this issue using getchar() to catch the ('\n') new char

If I understand well, you want to Join ScheduleRequest with User and apply the in clause to the userName property of the entity User.

I'd need to work a bit on this schema. But you can try with this trick, that is much more readable than the code you posted, and avoids the Join part (because it handles the Join logic outside the Criteria Query).

List<String> myList = new ArrayList<String> ();
for (User u : usersList) {
    myList.add(u.getUsername());
}
Expression<String> exp = scheduleRequest.get("createdBy");
Predicate predicate = exp.in(myList);
criteria.where(predicate);

In order to write more type-safe code you could also use Metamodel by replacing this line:

Expression<String> exp = scheduleRequest.get("createdBy");

with this:

Expression<String> exp = scheduleRequest.get(ScheduleRequest_.createdBy);

If it works, then you may try to add the Join logic into the Criteria Query. But right now I can't test it, so I prefer to see if somebody else wants to try.

Not a perfect answer though may be code snippets might help.

public <T> List<T> findListWhereInCondition(Class<T> clazz,
            String conditionColumnName, Serializable... conditionColumnValues) {
        QueryBuilder<T> queryBuilder = new QueryBuilder<T>(clazz);
        addWhereInClause(queryBuilder, conditionColumnName,
                conditionColumnValues);
        queryBuilder.select();
        return queryBuilder.getResultList();

    }


private <T> void addWhereInClause(QueryBuilder<T> queryBuilder,
            String conditionColumnName, Serializable... conditionColumnValues) {

        Path<Object> path = queryBuilder.root.get(conditionColumnName);
        In<Object> in = queryBuilder.criteriaBuilder.in(path);
        for (Serializable conditionColumnValue : conditionColumnValues) {
            in.value(conditionColumnValue);
        }
        queryBuilder.criteriaQuery.where(in);

    }

Your data is poorly formed. The value fields in particular have numerous spaces and new lines. Automated formatters won't work on this, as they will not modify the actual data. As you generate the data for output, filter it as needed to avoid the spaces.

Ctrl+C is what you need. If it didn't work, hit it harder. :-) Of course, you can also just close the shell window.

Edit: You didn't mention the circumstances. As a last resort, you could write a batch file that contains taskkill /im python.exe, and put it on your desktop, Start menu, etc. and run it when you need to kill a runaway script. Of course, it will kill all Python processes, so be careful.

Mac OSX 10.7.5: I tried setting my proxy in the settings.xml file (as mentioned by posters above) in the /conf directory and also in the ~/.m2 directory, but still I got this error. I downloaded the latest version of Maven (3.1.1), and set my PATH variable to reflect the latest install, and it worked for me right off the shelf without any error.

You have two options:

1. Use a Mark of the Web. This will enable a single html page to load. It See here for details. To do this, add the following to your web page below the doctype and above the html tag:

   <!-- saved from url=(0014)about:internet -->

2. Disable this feature. To do so go to Internet Options->Advanced->Security->Allow Active Content... Then close IE. When you restart IE, it will not give you this error.

Form the Inheritance concept, If some perticular method is not available in the current class it will search for that method in super classes. If available it executes.

It executes AbstractList<E> class add() method which throws UnsupportedOperationException.

When you are converting from an Array to a Collection Obejct. i.e., array-based to collection-based API then it is going to provide you fixed-size collection object, because Array's behaviour is of Fixed size.

java.util.Arrays.asList( T... a )

Souce samples for conformation.

public class Arrays {
    public static <T> List<T> asList(T... a) {
        return new java.util.Arrays.ArrayList.ArrayList<>(a); // Arrays Inner Class ArrayList
    }
    //...
    private static class ArrayList<E> extends AbstractList<E> implements RandomAccess, java.io.Serializable {
        //...
    }
}
public abstract class AbstractList<E> extends AbstractCollection<E> implements List<E> {
    public void add(int index, E element) {
        throw new UnsupportedOperationException();
    }
    public E set(int index, E element) {
        throw new UnsupportedOperationException();
    }
    public E remove(int index) {
        throw new UnsupportedOperationException();
    }

    public Iterator<E> iterator() {
        return new Itr();
    }
    private class Itr implements Iterator<E> {
        //...
    }

    public ListIterator<E> listIterator() {
        return listIterator(0);
    }
    private class ListItr extends Itr implements ListIterator<E> {
        //...
    }
}

Form the above Source you may observe that java.util.Arrays.ArrayList class doesn't @Override add(index, element), set(index, element), remove(index). So, From inheritance it executes super AbstractList<E> class add() function which throws UnsupportedOperationException.

As AbstractList<E> is an abstract class it provides the implementation to iterator() and listIterator(). So, that we can iterate over the list object.

List<String> list_of_Arrays = Arrays.asList(new String[] { "a", "b" ,"c"});

try {
    list_of_Arrays.add("Yashwanth.M");
} catch(java.lang.UnsupportedOperationException e) {
    System.out.println("List Interface executes AbstractList add() fucntion which throws UnsupportedOperationException.");
}
System.out.println("Arrays ? List : " + list_of_Arrays);

Iterator<String> iterator = list_of_Arrays.iterator();
while (iterator.hasNext()) System.out.println("Iteration : " + iterator.next() );

ListIterator<String> listIterator = list_of_Arrays.listIterator();
while (listIterator.hasNext())    System.out.println("Forward  iteration : " + listIterator.next() );
while(listIterator.hasPrevious()) System.out.println("Backward iteration : " + listIterator.previous());

You can even create Fixed-Size array form Collections class Collections.unmodifiableList(list);

Sample Source:

public class Collections {
    public static <T> List<T> unmodifiableList(List<? extends T> list) {
        return (list instanceof RandomAccess ?
                new UnmodifiableRandomAccessList<>(list) :
                new UnmodifiableList<>(list));
    }
}

A Collection — sometimes called a container — is simply an object that groups multiple elements into a single unit. Collections are used to store, retrieve, manipulate, and communicate aggregate data.

• Object Serialization uses the Serializable and Externalizable interfaces

You can use

try {
   user.OtherFriend = row["US_OTHERFRIEND"].ToString();
}
catch (Exception ex)
{
   // do something if you want 
}

    public class Main {

    public static List<String> list = new ArrayList();

    public static void main(String[] args) {

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

        l.add(222);
        l.add(100);
        l.add(45);
        l.add(415);
        l.add(311);

        l.sort(null);
        System.out.println(l.get(0));
    }
}

without l.sort(null) returned 222

with l.sort(null) returned 45

For a dynamic approach, if your labels are always in front of your text areas:

$(object).prev("label").text(charsleft);

JavaScript itself has terrible Date/Time API's. Nonetheless, you can do this in pure JavaScript:

Date.prototype.addHours = function(h) {
  this.setTime(this.getTime() + (h*60*60*1000));
  return this;
}

Sometimes, it may help switching off AllowAutoRedirect and setting both login POST and page GET requests the same user agent.

request.UserAgent = userAgent;
request.AllowAutoRedirect = false;

Well, it would be easier to exclude them in the first place:

authorsList = authorsList.Where(x => x.FirstName != "Bob").ToList();

However, that would just change the value of authorsList instead of removing the authors from the previous collection. Alternatively, you can use RemoveAll:

authorsList.RemoveAll(x => x.FirstName == "Bob");

If you really need to do it based on another collection, I'd use a HashSet, RemoveAll and Contains:

var setToRemove = new HashSet<Author>(authors);
authorsList.RemoveAll(x => setToRemove.Contains(x));

What a great bunch of answers - Now I've got a number of podcasts to add to my listening list!

My current list is StackOverflow, TWiT and Mac OS Ken. I tried to get into SERadio a few months ago but couldn't really engage myself with the podcast - Great introductory material, but I felt a lot of the shows were a bit 'beginner-y'.

For powershell in Windows, you can add relative path + filename to --output flag:

curl -L  http://github.com/GorvGoyl/Notion-Boost-browser-extension/archive/master.zip --output build_firefox/master-repo.zip

here build_firefox is relative folder.

sort method has been deprecated and replaced with sort_values. After converting to datetime object using df['Date']=pd.to_datetime(df['Date'])

df.sort_values(by=['Date'])

Note: to sort in-place and/or in a descending order (the most recent first):

df.sort_values(by=['Date'], inplace=True, ascending=False)

You can simply request https://graph.facebook.com/me?access_token=xxxxxxxxxxxxxxxxx if you get an error, the token is invalid. If you get a JSON object with an id property then it is valid.

Unfortunately this will only tell you if your token is valid, not if it came from your app.

ping (ICMP protocol) and ssh are two different protocols.

1. It could be that ssh service is not running or not installed

2. firewall restriction (local to server like iptables or even sshd config lock down ) or (external firewall that protects incomming traffic to network hosting 111.111.111.111)

First check is to see if ssh port is up

nc -v -w 1 111.111.111.111 -z 22

if it succeeds then ssh should communicate if not then it will never work until restriction is lifted or ssh is started

using just the shell,

while read -r col1 col2
do
  echo $col2 $col1
done <"file"

Unfortunately, C++ does not allow you to directly get a callable object referring to an object and one of its member functions. &Foo::doSomething gives you a "pointer to member function" which refers to the member function but not the associated object.

There are two ways around this, one is to use std::bind to bind the "pointer to member function" to the this pointer. The other is to use a lambda that captures the this pointer and calls the member function.

std::function<void(void)> f = std::bind(&Foo::doSomething, this);
std::function<void(void)> g = [this](){doSomething();};

I would prefer the latter.

With g++ at least binding a member function to this will result in an object three-pointers in size, assigning this to an std::function will result in dynamic memory allocation.

On the other hand, a lambda that captures this is only one pointer in size, assigning it to an std::function will not result in dynamic memory allocation with g++.

While I have not verified this with other compilers, I suspect similar results will be found there.

Just dropping a .js file into the entry point init folder works for this

e.g. entrypoint.js

var db = connect("mongodb://localhost/admin");

db.createUser(
    {
        user: "yourAdminUserName",
        pwd: "yourAdminPassword",
        roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
    }
)

docker-compose.yml:

db:
  image: mongo:3.2
  volumes:
   - /my/own/datadir:/data/db
   - ../mongo-entrypoint:/docker-entrypoint-initdb.d

Doing the rest by hand or more of the same works.

If you want to you can also drop a .sh file into the init folder to clean up the files so they are not laying around: zz-cleanup.sh.

There is some overhead with reflection, but it's a lot smaller on modern VMs than it used to be.

If you're using reflection to create every simple object in your program then something is wrong. Using it occasionally, when you have good reason, shouldn't be a problem at all.

It's not a direct answer to the question but you could just use the OR-operator

( grep "#SystemMaxUse=" journald.conf > /dev/null && sed -i 's/\#SystemMaxUse=/SystemMaxUse=50M/g' journald.conf ) || echo "This file has been edited. You'll need to do it manually."

Adding executable permissions, recursively, to all files (not folders) within the current folder with sh extension:

find . -name '*.sh' -type f | xargs chmod +x

* Notice the pipe (|)

Try enabling openssl extension in your php.ini if it is disabled. This way I could access the web service without need of any extra arguments, i.e.,

$client = new SoapClient(url);

I'd like to add that for accessibility, I think you should add focus trigger :

i.e. $("#popover").popover({ trigger: "hover focus" });

Use the TextBox's Exit event handler:

Private Sub TextBox1_Exit(ByVal Cancel As MSForms.ReturnBoolean)
    Logincode_Click  
End Sub

You may have to use urlencode on the string 'http://google.com/?var=234&key=234'

Well, like (almost) every console program for unix-like systems, git does not tell you anything if a command succeeds. It prints out something only if there's something wrong.

However if you want to be sure of what just happened, just type

git status

and see which changes are going to be committed and which not. I suggest you to use this before every commit, just to be sure that you are not forgetting anything.

Since you seem new to git, here is a link to a free online book that introduces you to git. It's very useful, it writes about basics as well as well known different workflows: http://git-scm.com/book

I had this issue(app doesn't want to open on notification click if app is in background or closed), and the problem was an invalid click_action in notification body, try removing or changing it to something valid.

Just cast each character to an int:

for (int i = 0; i < str.length; i++)  
  Console.Write(((int)str[i]).ToString());

You should set responseType: ResponseContentType.Blob in your GET-Request settings, because so you can get your image as blob and convert it later da base64-encoded source. You code above is not good. If you would like to do this correctly, then create separate service to get images from API. Beacuse it ism't good to call HTTP-Request in components.

Here is an working example:

Create image.service.ts and put following code:

Angular 4:

getImage(imageUrl: string): Observable<File> {
    return this.http
        .get(imageUrl, { responseType: ResponseContentType.Blob })
        .map((res: Response) => res.blob());
}

Angular 5+:

getImage(imageUrl: string): Observable<Blob> {
  return this.httpClient.get(imageUrl, { responseType: 'blob' });
}

Important: Since Angular 5+ you should use the new HttpClient.

The new HttpClient returns JSON by default. If you need other response type, so you can specify that by setting responseType: 'blob'. Read more about that here.

Now you need to create some function in your image.component.ts to get image and show it in html.

For creating an image from Blob you need to use JavaScript's FileReader. Here is function which creates new FileReader and listen to FileReader's load-Event. As result this function returns base64-encoded image, which you can use in img src-attribute:

imageToShow: any;

createImageFromBlob(image: Blob) {
   let reader = new FileReader();
   reader.addEventListener("load", () => {
      this.imageToShow = reader.result;
   }, false);

   if (image) {
      reader.readAsDataURL(image);
   }
}

Now you should use your created ImageService to get image from api. You should to subscribe to data and give this data to createImageFromBlob-function. Here is an example function:

getImageFromService() {
      this.isImageLoading = true;
      this.imageService.getImage(yourImageUrl).subscribe(data => {
        this.createImageFromBlob(data);
        this.isImageLoading = false;
      }, error => {
        this.isImageLoading = false;
        console.log(error);
      });
}

Now you can use your imageToShow-variable in HTML template like this:

<img [src]="imageToShow"
     alt="Place image title"

I hope this description is clear to understand and you can use it in your project.

See the working example for Angular 5+ here.

Well previously, I used the approach that you can find inside the WebElement:

WebElement baseTable = driver.findElement(By.tagName("table"));
WebElement tableRow = baseTable.findElement(By.xpath("//tr[2]")); //should be the third row
webElement cellIneed = tableRow.findElement(By.xpath("//td[2]"));
String valueIneed = cellIneed.getText();

Please note that I find inside the found WebElement instance.

The above is Java code, assuming that driver variable is healthy instance of WebDriver

simple java code  for change file permission in java  

   String path="D:\\file\\read.txt";
        File file=new File(path);
        if (file.exists()) {
            System.out.println("read="+file.canRead());
            System.out.println("write="+file.canWrite());
            System.out.println("Execute="+file.canExecute());
            file.setReadOnly();
        }

Combining phyzome's answer (which didn't work right away for me) with andreb's comment (which explains why it didn't) I ended up with this seemingly working code that temporarily disables NO_AUTO_CREATE_USER mode if it is active:

set @mode = @@SESSION.sql_mode;
set session sql_mode = replace(replace(@mode, 'NO_AUTO_CREATE_USER', ''), ',,', ',');
grant usage on *.* to 'myuser'@'%';
set session sql_mode = @mode;
drop user 'myuser'@'%';

can you try if.else

> col2=ifelse(df1$col=="true",1,0)
> df1
$col
[1] "true"  "false"

> cbind(df1$col)
     [,1]   
[1,] "true" 
[2,] "false"
> cbind(df1$col,col2)
             col2
[1,] "true"  "1" 
[2,] "false" "0" 

My guess is that RAND_MAX is equal to INT_MAX and so you're overflowing it to a negative.

Just do this:

r = ((double) rand() / (RAND_MAX)) + 1;

Or even better, use C++11's random number generators.

The best way to fix this:

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

A less insecure way to fix this:

'use strict';

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

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

agent = new https.Agent(agentOptions);

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

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

Other Options

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

agentOptions.ca = [ selfSignedRootCaPemCrtBuffer ];

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

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

Bad Idea

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

If you know the count of your columns (f.e. it's equal to a collection list). You can simply use this one liner to adjust all columns of one sheet (if you use at least java 8):

IntStream.range(0, columnCount).forEach((columnIndex) -> sheet.autoSizeColumn(columnIndex));

Personally, I think a language shouldn't make rules about coding style. It is a matter of preferences, usage, convenience, concept about readability.
Now, a project must set coding rules, for consistency across listings. You might not agree with these rules, but you should stick to them if you want to contribute (or work in a team).

At least, IDEs like Eclispe are agnostic, allowing to set rules like variable prefixes or suffixes, various styles of brace placement and space management, etc. So you can use it to reformat code along your guidelines.

Note: I am among those keeping their old habits from C/C++, coding Java with m_ prefixes for member variables (and s_ for static ones), prefixing booleans with an initial b, using an initial uppercase letter for function names and aligning braces... The horror for Java fundamentalists! ;-)
Funnily, that's the conventions used where I work... probably because the main initial developer comes from MFC world! :-D

Depends on your needs, but there is also a quick way to temporarily check your (dummy) JSON by saving your JSON on http://myjson.com. Copy the api link and paste that into your javascript code. Viola! When you want to deploy the codes, you must not forget to change that url in your codes!

This isn't C, but it's certainly does work. All the other methods I see here work by casing everything into parts of a hexagon, and approximating "angles" from that. By instead starting with a different equation using cosines, and solving for h s and v, you get a lot nicer relationship between hsv and rgb, and tweening becomes smoother (at the cost of it being way slower).

Assume everything is floating point. If r g and b go from 0 to 1, h goes from 0 to 2pi, v goes from 0 to 4/3, and s goes from 0 to 2/3.

The following code is written in Lua. It's easily translatable into anything else.

local hsv do
    hsv         ={}
    local atan2 =math.atan2
    local cos   =math.cos
    local sin   =math.sin

    function hsv.fromrgb(r,b,g)
        local c=r+g+b
        if c<1e-4 then
            return 0,2/3,0
        else
            local p=2*(b*b+g*g+r*r-g*r-b*g-b*r)^0.5
            local h=atan2(b-g,(2*r-b-g)/3^0.5)
            local s=p/(c+p)
            local v=(c+p)/3
            return h,s,v
        end
    end

    function hsv.torgb(h,s,v)
        local r=v*(1+s*(cos(h)-1))
        local g=v*(1+s*(cos(h-2.09439)-1))
        local b=v*(1+s*(cos(h+2.09439)-1))
        return r,g,b
    end

    function hsv.tween(h0,s0,v0,h1,s1,v1,t)
        local dh=(h1-h0+3.14159)%6.28318-3.14159
        local h=h0+t*dh
        local s=s0+t*(s1-s0)
        local v=v0+t*(v1-v0)
        return h,s,v
    end
end

Herman's solution worked for me, but the ... had me mixed up for a bit. I'm including the demo I worked up based on his answer. The additional features in my answer include foreign key support, auto incrementing keys, and use of the last_insert_rowid() function to get the last auto generated key in a transaction.

My need for this information came up when I hit a transaction that required three foreign keys but I could only get the last one with last_insert_rowid().

PRAGMA foreign_keys = ON;   -- sqlite foreign key support is off by default
PRAGMA temp_store = 2;      -- store temp table in memory, not on disk

CREATE TABLE Foo(
    Thing1 INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL
);

CREATE TABLE Bar(
    Thing2 INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL,
    FOREIGN KEY(Thing2) REFERENCES Foo(Thing1)
);

BEGIN TRANSACTION;

CREATE TEMP TABLE _Variables(Key TEXT, Value INTEGER);

INSERT INTO Foo(Thing1)
VALUES(2);

INSERT INTO _Variables(Key, Value)
VALUES('FooThing', last_insert_rowid());

INSERT INTO Bar(Thing2)
VALUES((SELECT Value FROM _Variables WHERE Key = 'FooThing'));

DROP TABLE _Variables;

END TRANSACTION;

I would start with upgrade of CMAKE version.

You can use INCLUDE_DIRECTORIES for header location and LINK_DIRECTORIES + TARGET_LINK_LIBRARIES for libraries

INCLUDE_DIRECTORIES(your/header/dir)
LINK_DIRECTORIES(your/library/dir)
rosbuild_add_executable(kinectueye src/kinect_ueye.cpp)
TARGET_LINK_LIBRARIES(kinectueye lib1 lib2 lib2 ...)

note that lib1 is expanded to liblib1.so (on Linux), so use ln to create appropriate links in case you do not have them

Build lists of matched lines - several flavors:

def lines_that_equal(line_to_match, fp):
    return [line for line in fp if line == line_to_match]

def lines_that_contain(string, fp):
    return [line for line in fp if string in line]

def lines_that_start_with(string, fp):
    return [line for line in fp if line.startswith(string)]

def lines_that_end_with(string, fp):
    return [line for line in fp if line.endswith(string)]

Build generator of matched lines (memory efficient):

def generate_lines_that_equal(string, fp):
    for line in fp:
        if line == string:
            yield line

Print all matching lines (find all matches first, then print them):

with open("file.txt", "r") as fp:
    for line in lines_that_equal("my_string", fp):
        print line

Print all matching lines (print them lazily, as we find them)

with open("file.txt", "r") as fp:
    for line in generate_lines_that_equal("my_string", fp):
        print line

Generators (produced by yield) are your friends, especially with large files that don't fit into memory.

Since at this point this question is almost a support group for people who suffer with various reasons on why WhatsApp wouldn't load the image preview, here's what was the root cause for my case, hoping it may help someone eventually:

Make sure the meta tag og:image content link is using HTTPS

When I made my website available through https, I forgot to specifically change the meta tags from http to https. Every other social media preview handled the image regardless, except for WhatsApp.

Simply making it https fixed it for me.

for (i>0; i--;)

is probably wrong and should be

for (; i>0; i--)

instead. Note where I put the semicolons. The condition goes in the middle, not at the start.

Since this question is quite old, but still comes up in google searches, I thought it would be good to point out the newer (and recommended) way to save Keras models. Instead of saving them using the older h5 format like has been shown before, it is now advised to use the SavedModel format, which is actually a dictionary that contains both the model configuration and the weights.

More information can be found here: https://www.tensorflow.org/guide/keras/save_and_serialize

The snippets to save & load can be found below:

model.fit(test_input, test_target)
# Calling save('my_model') creates a SavedModel folder 'my_model'.
model.save('my_model')

# It can be used to reconstruct the model identically.
reconstructed_model = keras.models.load_model('my_model')

A sample output of this :

String text = "Example";
EditText edtText = (EditText) findViewById(R.id.edtText);
edtText.setText(text);

Check it out EditText accept only String values if necessary convert it to string.

If int, double, long value, do:

String.value(value);

For those still struggling with the error, make sure that you also import ReactiveFormsModule in your component 's module.ts file

meaning that you will import your ReactiveFormsModule in your app.module.ts and also in your mycomponent.module.ts file

This problem looked familiar so I thought I'd see if I could replicate from the limited amount of information.

A quick search turned up an entry in James Bennett's blog here which mentions that when working with the UserProfile to extend the User model a common mistake in settings.py can cause Django to throw this error.

To quote the blog entry:

The value of the setting is not "appname.models.modelname", it's just "appname.modelname". The reason is that Django is not using this to do a direct import; instead, it's using an internal model-loading function which only wants the name of the app and the name of the model. Trying to do things like "appname.models.modelname" or "projectname.appname.models.modelname" in the AUTH_PROFILE_MODULE setting will cause Django to blow up with the dreaded "too many values to unpack" error, so make sure you've put "appname.modelname", and nothing else, in the value of AUTH_PROFILE_MODULE.

If the OP had copied more of the traceback I would expect to see something like the one below which I was able to duplicate by adding "models" to my AUTH_PROFILE_MODULE setting.

TemplateSyntaxError at /

Caught an exception while rendering: too many values to unpack

Original Traceback (most recent call last):
  File "/home/brandon/Development/DJANGO_VERSIONS/Django-1.0/django/template/debug.py", line 71, in render_node
    result = node.render(context)

    app_label, model_name = settings.AUTH_PROFILE_MODULE.split('.')
ValueError: too many values to unpack

This I think is one of the few cases where Django still has a bit of import magic that tends to cause confusion when a small error doesn't throw the expected exception.

You can see at the end of the traceback that I posted how using anything other than the form "appname.modelname" for the AUTH_PROFILE_MODULE would cause the line "app_label, model_name = settings.AUTH_PROFILE_MODULE.split('.')" to throw the "too many values to unpack" error.

I'm 99% sure that this was the original problem encountered here.

Here is my solution:

public long GetTime()
{
    DateTime dtCurTime = DateTime.Now.ToUniversalTime();

    DateTime dtEpochStartTime = Convert.ToDateTime("1/1/1970 0:00:00 AM");

    TimeSpan ts = dtCurTime.Subtract(dtEpochStartTime);

    double epochtime;

    epochtime = ((((((ts.Days * 24) + ts.Hours) * 60) + ts.Minutes) * 60) + ts.Seconds);   

    return Convert.ToInt64(epochtime);
}

Just an observation I just made while building naive code on OSX with cmake:

cmake ... -DBUILD_SHARED_LIBS=OFF ...

creates .so files

while

cmake ... -DBUILD_SHARED_LIBS=ON ...

creates .dynlib files.

Perhaps this helps anyone.

It works, when you use both lines:

Application.ActiveWorkbook.Worksheets("data").Range("C1", "C20000") = Format(Date, "yyyy-mm-dd")
Application.ActiveWorkbook.Worksheets("data").Range("C1", "C20000").NumberFormat = "yyyy-mm-dd"

If you want to remove only line terminators that are valid on the current OS, you could do this:

text = text.replaceAll(System.getProperty("line.separator"), "");

If you want to make sure you remove any line separators, you can do it like this:

text = text.replaceAll("\\r|\\n", "");

Or, slightly more verbose, but less regexy:

text = text.replaceAll("\\r", "").replaceAll("\\n", "");

You can also drag and drop "Execution Time" item from Built-in Fields list.

Try this below code for binding html through attr

.directive('dynamic', function ($compile) {
    return {
      restrict: 'A',
      replace: true,
      scope: { dynamic: '=dynamic'},
      link: function postLink(scope, element, attrs) {
        scope.$watch( 'attrs.dynamic' , function(html){
          element.html(scope.dynamic);
          $compile(element.contents())(scope);
        });
      }
    };
  });

Try this element.html(scope.dynamic); than element.html(attr.dynamic);

This worked for me

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

For unsigned data type there is no sign bit and all bits are for data ; whereas for signed data type MSB is indicated sign bit and remaining bits are for data.

To find the range do following things :

Step:1 -> Find out no of bytes for the give data type.

Step:2 -> Apply following calculations.

      Let n = no of bits in data type  

      For signed data type ::
            Lower Range = -(2^(n-1)) 
            Upper Range = (2^(n-1)) - 1)  

      For unsigned data type ::
            Lower Range = 0 
            Upper Range = (2^(n)) - 1 

For e.g.

For unsigned int size = 4 bytes (32 bits) --> Range [0 , (2^(32)) - 1]

For signed int size = 4 bytes (32 bits) --> Range [-(2^(32-1)) , (2^(32-1)) - 1]

If you can't use Joda time and you still live in the dark world :) ( Java 5 or lower ) you can enjoy this :

Note: Make sure your date is allready made by the format : dd/MM/YYYY

/**
Make an int Month from a date
*/
public static int getMonthInt(Date date) {

    SimpleDateFormat dateFormat = new SimpleDateFormat("MM");
    return Integer.parseInt(dateFormat.format(date));
}

/**
Make an int Year from a date
*/
public static int getYearInt(Date date) {

    SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy");
    return Integer.parseInt(dateFormat.format(date));
}

Make a script like this:

#!/bin/bash

echo $((0x$1)).$((0x$2)).$((0x$3)).$((0x$4))

Example:

sh converthextoip.sh c0 a8 00 0b

Result:

192.168.0.11

To undo: C-_

To redo after a undo: C-g C-_

Type multiple times on C-_ to redo what have been undone by C-_ To redo an emacs command multiple times, execute your command then type C-xz and then type many times on z key to repeat the command (interesting when you want to execute multiple times a macro)

Here is simple practical explanation:Simply explained here

In call.service.ts

import { Observable } from 'rxjs';
import { Subject } from 'rxjs/Subject';

@Injectable()
export class CallService {
 private subject = new Subject<any>();

 sendClickCall(message: string) {
    this.subject.next({ text: message });
 }

 getClickCall(): Observable<any> {
    return this.subject.asObservable();
 }
}

Component from where you want to call observable to inform another component that button is clicked

import { CallService } from "../../../services/call.service";

export class MarketplaceComponent implements OnInit, OnDestroy {
  constructor(public Util: CallService) {

  }

  buttonClickedToCallObservable() {
   this.Util.sendClickCall('Sending message to another comp that button is clicked');
  }
}

Component where you want to perform action on button clicked on another component

import { Subscription } from 'rxjs/Subscription';
import { CallService } from "../../../services/call.service";


ngOnInit() {

 this.subscription = this.Util.getClickCall().subscribe(message => {

 this.message = message;

 console.log('---button clicked at another component---');

 //call you action which need to execute in this component on button clicked

 });

}

import { Subscription } from 'rxjs/Subscription';
import { CallService } from "../../../services/call.service";


ngOnInit() {

 this.subscription = this.Util.getClickCall().subscribe(message => {

 this.message = message;

 console.log('---button clicked at another component---');

 //call you action which need to execute in this component on button clicked

});

}

My understanding clear on components communication by reading this: http://musttoknow.com/angular-4-angular-5-communicate-two-components-using-observable-subject/

• Hit F12 to open Dev Tools
• Click the Sources tab
• On right-hand side, scroll down to "Event Listener Breakpoints", and expand tree
• Click on the events you want to listen for.
• Interact with the target element, if they fire you will get a break point in the debugger

Similarly, you can right click on the target element -> select "inspect element" Scroll down on the right side of the dev frame, at the bottom is 'event listeners'. Expand the tree to see what events are attached to the element. Not sure if this works for events that are handled through bubbling (I'm guessing not)

The key is to use $(window).load(function(){} so we know the image is loaded. Hide the image via the css function then fade it in using fadeIn:

$(function() {

  $(window).load(function(){
    $('#logo').css({visibility: 'visible', opacity: 0}).fadeIn(1000);
  });

});

Sharing my generalized solution for handling TextView compound drawable click and touch events.

First we need a touch event handler:

     * @param drawableBounds {@link Rect} with compound drawable bounds relative to wrapping view.

     * If using fuzz, may return negative coordinates.
     */
    protected abstract boolean onDrawableTouch(View v, int drawableIndex, Rect drawableBounds, MotionEvent event);
}

Now you can process any touch events on any compound drawable of any TextView you like this way:

textView1.setOnTouchListener(new CompoundDrawableTouchListener() {
            @Override
            protected void onDrawableTouch(View v, int drawableIndex, Rect drawableBounds, MotionEvent event) {
                switch(v.getId()) {
                    case R.id.textView1:
                        switch(drawableIndex) {
                            case CompoundDrawableTouchListener.RIGHT:
                                doStuff();
                                break;
                        }
                        break;
                }
            }
        });

Only interested in clicks? Just filter out by MotionEvent action:

/**
 * Handles compound drawable click events.
 * @see TextView#getCompoundDrawables()
 * @see TextView#setCompoundDrawablesRelativeWithIntrinsicBounds(int, int, int, int)
 * @see CompoundDrawableTouchListener
 */
public abstract class CompoundDrawableClickListener extends CompoundDrawableTouchListener {

    /**
     * Default constructor
     */
    public CompoundDrawableClickListener() {
        super();
    }

     /**
     * Constructor with fuzz
     * @param fuzz desired fuzz in px
     */
    public CompoundDrawableClickListener(int fuzz) {
        super(fuzz);
    }

    @Override
    protected void onDrawableTouch(View v, int drawableIndex, Rect drawableBounds, MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_UP) onDrawableClick(v, drawableIndex);
        return true;
    }

    /**
     * Compound drawable touch-event handler
     * @param v wrapping view
     * @param drawableIndex index of compound drawable which recicved the event
     */
    protected abstract void onDrawableClick(View v, int drawableIndex);
}

Again we can easily handle clicks on any compound drawable of any TextView:

textView1.setOnTouchListener(new CompoundDrawableClickListener() {
            @Override
            protected void onDrawableClick(View v, int drawableIndex) {
                switch(v.getId()) {
                    case R.id.textView1:
                        switch(drawableIndex) {
                            case CompoundDrawableTouchListener.RIGHT:
                                doStuff();
                                break;
                        }
                        break;
                }
            }
        });

Hope you liked it as I did. I will try to keep it updated here and in related gist if anything changes.

Start Activity2 with startActivityForResult and use setResult method for sending data back from Activity2 to Activity1. In Activity1 you will need to override onActivityResult for updating TextView with EditText data from Activity2.

For example:

In Activity1, start Activity2 as:

Intent i = new Intent(this, Activity2.class);
startActivityForResult(i, 1);

In Activity2, use setResult for sending data back:

Intent intent = new Intent();
intent.putExtra("editTextValue", "value_here")
setResult(RESULT_OK, intent);        
finish();

And in Activity1, receive data with onActivityResult:

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == 1) {
         if(resultCode == RESULT_OK) {
             String strEditText = data.getStringExtra("editTextValue");
         }     
    }
} 

If you can, also use SharedPreferences for sharing data between Activities.

This is just a version thing. Since Python 3.x the print is actually a function, so it now takes arguments like any normal function.

The end=' ' is just to say that you want a space after the end of the statement instead of a new line character. In Python 2.x you would have to do this by placing a comma at the end of the print statement.

For example, when in a Python 3.x environment:

while i<5:
    print(i)
    i=i+1

Will give the following output:

0
1
2
3
4

Where as:

while i<5:
    print(i, end = ' ')
    i=i+1

Will give as output:

0 1 2 3 4

Checkboxes are a control type designed for one purpose: to ensure valid entry of Boolean values.

In Access, there are two types:

1. 2-state -- can be checked or unchecked, but not Null. Values are True (checked) or False (unchecked). In Access and VBA, the value of True is -1 and the value of False is 0. For portability with environments that use 1 for True, you can always test for False or Not False, since False is the value 0 for all environments I know of.

2. 3-state -- like the 2-state, but can be Null. Clicking it cycles through True/False/Null. This is for binding to an integer field that allows Nulls. It is of no use with a Boolean field, since it can never be Null.

Minor quibble with the answers:

There is almost never a need to use the .Value property of an Access control, as it's the default property. These two are equivalent:

  ?Me!MyCheckBox.Value
  ?Me!MyCheckBox

The only gotcha here is that it's important to be careful that you don't create implicit references when testing the value of a checkbox. Instead of this:

  If Me!MyCheckBox Then

...write one of these options:

  If (Me!MyCheckBox) Then  ' forces evaluation of the control

  If Me!MyCheckBox = True Then

  If (Me!MyCheckBox = True) Then

  If (Me!MyCheckBox = Not False) Then

Likewise, when writing subroutines or functions that get values from a Boolean control, always declare your Boolean parameters as ByVal unless you actually want to manipulate the control. In that case, your parameter's data type should be an Access control and not a Boolean value. Anything else runs the risk of implicit references.

Last of all, if you set the value of a checkbox in code, you can actually set it to any number, not just 0 and -1, but any number other than 0 is treated as True (because it's Not False). While you might use that kind of thing in an HTML form, it's not proper UI design for an Access app, as there's no way for the user to be able to see what value is actually be stored in the control, which defeats the purpose of choosing it for editing your data.

sometimes you need to set Padding, not Margin to make space between items smaller than default

Here is the code that works for me. The key is that you need a wrapper class.

public class Person {

    private String name;
    private Integer age;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    @Override
    public String toString() {
        return "Person [name=" + name + ", age=" + age + "]";
    }

A PersonWrapper class

public class PersonWrapper {

    private List<Person> persons;

    /**
     * @return the persons
     */
    public List<Person> getPersons() {
        return persons;
    }

    /**
     * @param persons the persons to set
     */
    public void setPersons(List<Person> persons) {
        this.persons = persons;
    }
}

My Controller methods

@RequestMapping(value="person", method=RequestMethod.POST,consumes="application/json",produces="application/json")
    @ResponseBody
    public List<String> savePerson(@RequestBody PersonWrapper wrapper) {
        List<String> response = new ArrayList<String>();
        for (Person person: wrapper.getPersons()){
        personService.save(person);
         response.add("Saved person: " + person.toString());
    }
        return response;
    }

The request sent is json in POST

{"persons":[{"name":"shail1","age":"2"},{"name":"shail2","age":"3"}]}

And the response is

["Saved person: Person [name=shail1, age=2]","Saved person: Person [name=shail2, age=3]"]

On IPython 2.2.0, just typing l (lowercase L) on command mode (activated by typing Esc) works. See [Help] - [Keyboard Shortcuts] for other shortcuts.

Also, you can set default behavior to display line numbers by editing custom.js.

To answer your extra question:

You can set which rows should be repeated on every page using:

$objPHPExcel->getActiveSheet()->getPageSetup()->setRowsToRepeatAtTopByStartAndEnd(1, 5);

Now, row 1, 2, 3, 4 and 5 will be repeated.

You can copy a string in python via string formatting :

>>> a = 'foo'  
>>> b = '%s' % a  
>>> id(a), id(b)  
(140595444686784, 140595444726400)  

Well, I assume you are not on Interactive Mode and you used this code to decode your string:

import base64

base64.b64decode(your_string)

Well first of all you need to assign the finished product to a variable to be able to be printed out:

code_string = base64.b64decode(your_string)

Then like any beginner programmer would know, you would print the results out: Python 2.7x:

print code_string

Python 3.x:

print(code_string)

After the successful decoding, you will get a string about the size of the not yet decoded string. I hope this helps you!

I just had this problem

1. Having multiple user using the same repo caused the problem
2. Logout evey other user using the repo

Hope this helps

What is a patch?

A patch is little more (see below) than a series of instructions: "add this here", "remove that there", "change this third thing to a fourth". That's why git tells you:

The copy of the patch that failed is found in:
c:/.../project2/.git/rebase-apply/patch

You can open that patch in your favorite viewer or editor, open the files-to-be-changed in your favorite editor, and "hand apply" the patch, using what you know (and git does not) to figure out how "add this here" is to be done when the files-to-be-changed now look little or nothing like what they did when they were changed earlier, with those changes delivered to you as a patch.

A little more

A three-way merge introduces that "little more" information than the plain "series of instructions": it tells you what the original version of the file was as well. If your repository has the original version, your git can compare what you did to a file, to what the patch says to do to the file.

As you saw above, if you request the three-way merge, git can't find the "original version" in the other repository, so it can't even attempt the three-way merge. As a result you get no conflict markers, and you must do the patch-application by hand.

Using --reject

When you have to apply the patch by hand, it's still possible that git can apply most of the patch for you automatically and leave only a few pieces to the entity with the ability to reason about the code (or whatever it is that needs patching). Adding --reject tells git to do that, and leave the "inapplicable" parts of the patch in rejection files. If you use this option, you must still hand-apply each failing patch, and figure out what to do with the rejected portions.

Once you have made the required changes, you can git add the modified files and use git am --continue to tell git to commit the changes and move on to the next patch.

What if there's nothing to do?

Since we don't have your code, I can't tell if this is the case, but sometimes, you wind up with one of the patches saying things that amount to, e.g., "fix the spelling of a word on line 42" when the spelling there was already fixed.

In this particular case, you, having looked at the patch and the current code, should say to yourself: "aha, this patch should just be skipped entirely!" That's when you use the other advice git already printed:

If you prefer to skip this patch, run "git am --skip" instead.

If you run git am --skip, git will skip over that patch, so that if there were five patches in the mailbox, it will end up adding just four commits, instead of five (or three instead of five if you skip twice, and so on).

The website you linked doesn't changes the image's width but it actually cuts it off. For that it needs to be set as a background-image.

For more info about background-image look it at http://www.w3schools.com/cssref/pr_background-image.asp

Usage:

#divID {
    background-image:url(image_url);
    -webkit-background-size: cover;
    -moz-background-size: cover;
    -o-background-size: cover;
    background-size: cover;
}

For anyone who is looking to enable this on the Mac version, it is not available. Developers of Visual Studio stated they will include in their roadmap.

Thanks for your feed back got it to work I used the sshpass tool.

sshpass -p 'password' scp [email protected]:sys_config /var/www/dev/

The stringfy method is not for parsing JSON, it's for turning an object into a JSON string.

The JSON is parsed by jQuery when you load it, you don't need to parse the data to use it. Just use the string in the data:

$('div#ListingData').text(data.data.items[0].links[1].caption);

I had this problem too, and in my case I found that the color of the font was the same color of the background, so it looked like nothing happened.

I am trying to check if a key exist in an array in angular way and landed here on this question. In my Angularjs 1.4 ternary operator worked like below

{{ CONDITION ? TRUE : FALSE }}

hence for the array key exist i did a simple JS check

Solution 1 : {{ array['key'] !== undefined ? array['key'] : 'n/a' }}

Solution 2 : {{ "key" in array ? array['key'] : 'n/a' }}

In my case other solutions did not work than this way:

$('.bootstrap-filestyle :input').val('');

However, if you will have more than 1 file input on page, it will reset the text on all of them.

Make your life easy when working with dates, timestamps and durations. Use HalDateTime from

http://sourceforge.net/projects/haldatetime/?source=directory

For example you can just use it to parse your input like this:

HalDateTime mydate = HalDateTime.valueOf( "25.12.1988" );
System.out.println( mydate );   // will print in ISO format: 1988-12-25

You can also specify patterns for parsing and printing.

In c++11 you can use:

for ( auto iter : table ) {
     key=iter->first;
     value=iter->second;
}

You could set up a cron job to run on every day of the month, and have it run a shell script like the following. This script works out whether tomorrow's day number is less than today's (i.e. if tomorrow is a new month), and then does whatever you want.

TODAY=`date +%d`
TOMORROW=`date +%d -d "1 day"`

# See if tomorrow's day is less than today's
if [ $TOMORROW -lt $TODAY ]; then
echo "This is the last day of the month"
# Do stuff...

If you don't need 100% support for IE6 with javascript disabled you could use something like ie7-js with IE conditional comments. Then you just use css rules to apply hover effects. I don't know exactly how it works but it uses javascript to make a lot of css rules work that don't normally in IE7 and 8.

You can use TimerTask for Cronjobs.

Main.java

public class Main{
   public static void main(String[] args){

     Timer t = new Timer();
     MyTask mTask = new MyTask();
     // This task is scheduled to run every 10 seconds

     t.scheduleAtFixedRate(mTask, 0, 10000);
   }

}

MyTask.java

class MyTask extends TimerTask{

   public MyTask(){
     //Some stuffs
   }

   @Override
   public void run() {
     System.out.println("Hi see you after 10 seconds");
   }

}

Alternative You can also use ScheduledExecutorService.

If your class extends Serializable, you can write and read objects through a ByteArrayOutputStream, that's what I usually do.

I just had to remove the table from the model and update the model again bringing the table back. I guess the primary key was created after the table was pulled into the model.

This example made everything clear for me:
As you can see setSoTimeout prevent the program to hang! It wait for SO_TIMEOUT time! if it does not get any signal it throw exception! It means that time expired!

import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;
import java.net.SocketTimeoutException;

public class SocketTest extends Thread {
  private ServerSocket serverSocket;

  public SocketTest() throws IOException {
    serverSocket = new ServerSocket(8008);
    serverSocket.setSoTimeout(10000);
  }

  public void run() {
    while (true) {
      try {
        System.out.println("Waiting for client on port " + serverSocket.getLocalPort() + "...");
        Socket client = serverSocket.accept();

        System.out.println("Just connected to " + client.getRemoteSocketAddress());
        client.close();
      } catch (SocketTimeoutException s) {
        System.out.println("Socket timed out!");
        break;
      } catch (IOException e) {
        e.printStackTrace();
        break;
      }
    }
  }

  public static void main(String[] args) {
    try {
      Thread t = new SocketTest();
      t.start();
    } catch (IOException e) {
      e.printStackTrace();
    }
  }
}

I just found a simple solution. You can drag an opened file and move towards the four sides of the Editor, it will show a highlighted area that you can drop to. It will split the view automatically, either horizontally, vertically, or even into three rows.

VSCode v1.30.2

Update: you can also drag a file from the Explorer to split the Editor in the same way above.

Two ways, using system default install path, usually /usr/lib/x86_64-linux-gnu/:

find_package(Boost REQUIRED regex date_time system filesystem thread graph)
include_directories(${BOOST_INCLUDE_DIRS})
message("boost lib: ${Boost_LIBRARIES}")
message("boost inc:${Boost_INCLUDE_DIR}")

add_executable(use_boost use_boost.cpp)
target_link_libraries(use_boost
        ${Boost_LIBRARIES}
        )

If you install Boost in a local directory or choose local install instead of system install, you can do it by this:

set( BOOST_ROOT "/home/xy/boost_install/lib/" CACHE PATH "Boost library path" )
set( Boost_NO_SYSTEM_PATHS on CACHE BOOL "Do not search system for Boost" )

find_package(Boost REQUIRED regex date_time system filesystem thread graph)
include_directories(${BOOST_INCLUDE_DIRS})
message("boost lib: ${Boost_LIBRARIES}, inc:${Boost_INCLUDE_DIR}")

add_executable(use_boost use_boost.cpp)
target_link_libraries(use_boost
        ${Boost_LIBRARIES}
        )

Note the above dir /home/xy/boost_install/lib/ is where I install Boost:

xy@xy:~/boost_install/lib$ ll -th
total 16K
drwxrwxr-x 2 xy xy 4.0K May 28 19:23 lib/
drwxrwxr-x 3 xy xy 4.0K May 28 19:22 include/

.......

adjust the background-position to move background images in different positions of the div

div { 
       background-image: url('image url')
       background-position: 0 -250px; 
    }

Another way to refresh the current page using selenium in Java.

//first: get the current URL in a String variable
String currentURL = driver.getCurrentUrl(); 
//second: call the current URL
driver.get(currentURL); 

Using this will refresh the current page like clicking the address bar of the browser and pressing enter.

<?php  
header('Location: http://www.google.com'); //Send browser to http://www.google.com
?>  

I think the easiest (and maybe most elegant) solution here is to leverage the fact that you can set default to a callable. So, to get around admin's special handling of auto_now, you can just declare the field like so:

from django.utils import timezone
date_field = models.DateField(default=timezone.now)

It's important that you don't use timezone.now() as the default value wouldn't update (i.e., default gets set only when the code is loaded). If you find yourself doing this a lot, you could create a custom field. However, this is pretty DRY already I think.

I have done this in the past.

SELECT column_name
FROM information_schema.columns
WHERE table_name='insert table name here'; 

This is my customized factory providing a customized names for thread dump analyzers. Usually I just give tf=null to reuse JVM default thread factory. This website has more advanced thread factory.

public class SimpleThreadFactory implements ThreadFactory {
    private ThreadFactory tf;
    private String nameSuffix;

    public SimpleThreadFactory (ThreadFactory tf, String nameSuffix) {
        this.tf = tf!=null ? tf : Executors.defaultThreadFactory();
        this.nameSuffix = nameSuffix; 
    }

    @Override public Thread newThread(Runnable task) {
        // default "pool-1-thread-1" to "pool-1-thread-1-myapp-MagicTask"
        Thread thread=tf.newThread(task);
        thread.setName(thread.getName()+"-"+nameSuffix);
        return thread;
    }
}

- - - - - 

ExecutorService es = Executors.newFixedThreadPool(4, new SimpleThreadFactory(null, "myapp-MagicTask") );

For your convenience this is a thread dump loop for debug purpose.

    ThreadMXBean mxBean=ManagementFactory.getThreadMXBean();
    long[] tids = mxBean.getAllThreadIds();
    System.out.println("------------");
    System.out.println("ThreadCount="+tids.length);
    for(long tid : tids) {
        ThreadInfo mxInfo=mxBean.getThreadInfo(tid);
        if (mxInfo==null) {
            System.out.printf("%d %s\n", tid, "Thread not found");
        } else {
            System.out.printf("%d %s, state=%s, suspended=%d, lockowner=%d %s\n"
                    , mxInfo.getThreadId(), mxInfo.getThreadName()
                    , mxInfo.getThreadState().toString()
                    , mxInfo.isSuspended()?1:0
                    , mxInfo.getLockOwnerId(), mxInfo.getLockOwnerName()
            );
        }
    }

From a performance point of view, I guess that a direct SQL query using the EXISTS command would be appropriate. See here for how to execute SQL directly in Entity Framework: http://blogs.microsoft.co.il/blogs/gilf/archive/2009/11/25/execute-t-sql-statements-in-entity-framework-4.aspx

Concerning n00b's comment: "I get the following warning: A value is trying to be set on a copy of a slice from a DataFrame. Try using .loc[row_indexer,col_indexer] = value instead"

I was getting the same error. In my case it was because I was trying to perform the column addition on a dataframe that was created like this:

df_b = df[['colA', 'colB', 'colC']]

instead of:

df_c = pd.DataFrame(df, columns=['colA', 'colB', 'colC'])

df_b is a copy of a slice from df
df_c is an new dataframe. So

df_c['colD'] = df['colA'] + df['colB']+ df['colC']

will add the columns and won't raise any warning. Same if .sum(axis=1) is used.

When having large ("wide") arrays, instead of moving each element of a long row of data around, use a one-dimensional array with indexes of the array.

initialize ptr_arr with 0,1,2,3,..uBound(arr) then access data with

arr(field_index,ptr_arr(row_index))

instead of

arr(field_index,row_index)

and just swap the elements of ptr_arr instead of swapping the rows.

If you are processing the array row by row, eg displaying it as a , you can take the lookout out of the inner loop:

max_col=uBound(arr,1)
response.write "<table>"
for n = 0 to uBound(arr,2)
  response.write "<tr>"
  row=ptr_arr(n)
  for i=0 to max_col
    response.write "<td>"&arr(i,row)&"</td>"
  next
  response.write "</tr>
next
response.write "</table>" 

This is documented in the 'R Installation and Administration' manual that came with your installation.

On my Linux box:

R> .libPaths()
[1] "/usr/local/lib/R/site-library" "/usr/lib/R/site-library"      
[3] "/usr/lib/R/library"           
R> 

meaning that the default path is the first of these. You can override that via an argument to both install.packages() (from inside R) or R CMD INSTALL (outside R).

You can also override by setting the R_LIBS_USER variable.

\ => \\ and " => \"

so Replace("\\\"","")

You can use string.punctuation with built-in NLTK stopwords list:

from nltk.tokenize import word_tokenize, sent_tokenize
from nltk.corpus import stopwords
from string import punctuation

words = tokenize(text)
wordsWOStopwords = removeStopWords(words)

def tokenize(text):
        sents = sent_tokenize(text)
        return [word_tokenize(sent) for sent in sents]

def removeStopWords(words):
        customStopWords = set(stopwords.words('english')+list(punctuation))
        return [word for word in words if word not in customStopWords]

NLTK stopwords complete list

I'm not sure how stuck you are:

You must have a web server (Windows comes with one called IIS, but it may not be installed)

1. Make sure you actually have IIS installed! Try typing http://localhost/ in your browser and see what happens. If nothing happens it means that you may not have IIS installed. See Installing IIS
2. Set up IIS How to set up your first IIS Web site
3. You may even need to Install the .NET Framework (or your server will only serve static html pages, and not asp.net pages)

Installing your application

Once you have done that, you can more or less just copy your application to c:\wwwroot\inetpub\. Read Installing ASP.NET Applications (IIS 6.0) for more information

Accessing the web site from another machine

In theory, once you have a web server running, and the application installed, you only need the IP address of your web server to access the application.

To find your IP address try: Start -> Run -> type cmd (hit ENTER) -> type ipconfig (hit ENTER)

Once

• you have the IP address AND
• IIS running AND
• the application is installed

you can access your website from another machine in your LAN by just typing in the IP Address of you web server and the correct path to your application.

If you put your application in a directory called NewApp, you will need to type something like http://your_ip_address/NewApp/default.aspx

Turn off your firewall

If you do have a firewall turn it off while you try connecting for the first time, you can sort that out later.

I seem to be having success doing

org.jboss.logmanager.Logger logger = org.jboss.logmanager.Logger.getLogger("");
logger.setLevel(java.util.logging.Level.ALL);

Then to get detailed logging from netty, the following has done it

org.slf4j.impl.SimpleLogger.setLevel(org.slf4j.impl.SimpleLogger.TRACE);

put the logic in

afterTextChanged(Editable s) {
    string str = s.toString()
    // use the string str
}

I had the same issue with a valid signed wildcard certificate from symantec.

First try running your java application with -Djavax.net.debug=SSL to see what is really going on.

I ended up importing the intermediate certificate which was causing the cert chain to break.

I downloaded the missing intermediate cert from symantec (you can see the download link to the missing cert in the ssl handshake log: http://svrintl-g3-aia.verisign.com/SVRIntlG3.cer in my case).

And I imported the cert in the java keystore. After importing the intermediate certificate my wildcard ssl cert finally started working:

keytool -import -keystore ../jre/lib/security/cacerts -trustcacerts -alias "VeriSign Class 3 International Server CA - G3" -file /pathto/SVRIntlG3.cer

Download it from here:

http://www.iis.net/downloads/microsoft/url-rewrite

or if you already have Web Platform Installer on your machine you can install it from there.

In a multi-project solution, you usually want to have one configuration that generates no PDB or XML files at all. Instead of changing the Debug Info property of every project to none, I thought it would be more expedient to add a post-build event that only works in a specific configuration.

Unfortunately, Visual Studio doesn't allow you to specify different post-build events for different configurations. So I decided to do this manually, by editing the csproj file of the startup project and adding the following (instead of any existing PostBuildEvent tag):

  <PropertyGroup Condition="'$(Configuration)' == 'Publish'">
    <PostBuildEvent>
        del *.pdb
        del *.xml
    </PostBuildEvent>
  </PropertyGroup>

Unfortunately, this will make the post build event textbox blank and putting anything in it can have unpredictable results.

If you have MySQL installed through Homebrew these commands will help you:

# For starting
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

# For stoping
launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

I'd like to add one more difference which makes sense. For example, you have a framework with thousands of lines of code. Now if you want to add a new feature throughout the code using a method enhanceUI(), then it's better to add that method in abstract class rather in interface. Because, if you add this method in an interface then you should implement it in all the implemented class but it's not the case if you add the method in abstract class.

when your add permission in manifest then in eclipse go to project and clic

$http methods return a promise, which can't be iterated, so you have to attach the results to the scope variable through the callbacks:

$scope.documents = [];
$http.get('/Documents/DocumentsList/' + caseId)
  .then(function(result) {
    $scope.documents = result.data;
});

Now, since this defines the documents variable only after the results are fetched, you need to initialise the documents variable on scope beforehand: $scope.documents = []. Otherwise, your ng-repeat will choke.

This way, ng-repeat will first return an empty list, because documents array is empty at first, but as soon as results are received, ng-repeat will run again because the `documents``have changed in the success callback.

Also, you might want to alter you ng-repeat expression to:

<li ng-repeat="document in documents" ng-class="IsFiltered(document.Filtered)">

because if your DisplayDocuments() function is making a call to the server, than this call will be executed many times over, due to the $digest cycles.

For VS2019 I was able to signup with my github account:

Then it will send password to your email and you will be able to sign.

A newer version with es6 spread operator:

[...Array(30)].map(() => Math.random().toString(36)[2]).join('')

• The 30 is an arbitrary number, you can pick any token length you want
• The 36 is the maximum radix number you can pass to numeric.toString(), which means all numbers and a-z lowercase letters
• The 2 is used to pick the 3rd index from the random string which looks like this: "0.mfbiohx64i", we could take any index after 0.

For anyone completely new to Qt Creator like me, you can modify your project's .pro file from within Qt Creator:

Just double-click on "your project name".pro in the Projects window and add the include path at the bottom of the .pro file like I've done.

Or add "sort name" to list alphabetically

QUICK SOLUTION EVERY STEP:

Fixed error in VMware Workstation on Windows 10 host Transport (VMDB) error -14: Pipe connection has been broken.

Today we will be fixing VMWare error on a windows 10 computer.

1. In RUN box type "gpedit" then Goto [ERROR SEE POINT 3]

1- Computer Configuration

2- Administrative Templates

3- System - Device Guard : IF NO DEVICE GUARD : (DOWNLOAD https://www.microsoft.com/en-us/download/100591 install this "c:\Program Files (x86)\Microsoft Group Policy\Windows 10 November 2019 Update (1909)\PolicyDefinitions" COPY to c:\windows\PolicyDefinitions )

4- Turn on Virtualization Based Security. Now Double click that and "Disable"

2. Open Command Prompt as Administrator and type the following gpupdate /force [DONT DO IF YOU DONT HAVE DEVICE GUARD ELSE IT WILL GO AGAIN]

3. Open Registry Editor, now Go to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\DeviceGuard. Add a new DWORD value named EnableVirtualizationBasedSecurity and set it to 0 to disable it. Next Go to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\LSA. Add a new DWORD value named LsaCfgFlags and set it to 0 to disable it.

4. In RUN box, type Turn Windows features on or off, now uncheck Hyper-V and restart system.

5. Open command prompt as a administrator and type the following commands

    bcdedit /create {0cb3b571-2f2e-4343-a879-d86a476d7215} /d "DebugTool" /application osloader

    bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} path "\EFI\Microsoft\Boot\SecConfig.efi"

    bcdedit /set {bootmgr} bootsequence {0cb3b571-2f2e-4343-a879-d86a476d7215}

    bcdedit /set hypervisorlaunchtype off

Now, Restart your system

A regex can also be used to split words.

\w can be used to match word characters ([A-Za-z0-9_]), so that punctuation is removed from the results:

String s = "I want to walk my dog, and why not?";
Pattern pattern = Pattern.compile("\\w+");
Matcher matcher = pattern.matcher(s);
while (matcher.find()) {
    System.out.println(matcher.group());
}

Outputs:

I
want
to
walk
my
dog
and
why
not

See Java API documentation for Pattern

I believe this is caused by HSTS - see http://en.wikipedia.org/wiki/HTTP_Strict_Transport_Security

If you have (developed) any other localhost sites which send a HSTS header...

eg. Strict-Transport-Security: max-age=31536000; includeSubDomains; preload

...then depending on the value of max-age, future requests to localhost will be required to be served over HTTPS.

To get around this, I did the following.

• In the Chrome address bar type "chrome://net-internals/#hsts"
• At the very bottom of a page is QUERY domain textbox - verify that localhost is known to the browser. If it says "Not found" then this is not the answer you are looking for.
• If it is, DELETE the localhost domain using the textbox above
• Your site should now work using plain old HTTP

This is not a permanent solution, but will at least get it working between projects. If anyone knows how to permanently exclude localhost from the HSTS list please let me know :)

UPDATE - November 2017

Chrome has recently moved this setting to sit under Delete domain security policies

UPDATE - December 2017 If you are using .dev domain see other answers below as Chrome (and others) force HTTPS via preloaded HSTS.

url ='http://www.test.com/page/TEST2'.split('/')[4]
print url

Output: TEST2.

If you want one row for each filename, reflecting a specific states and listing the most recent date then this is your friend:

select filename ,
       status   ,
       max_date = max( dates )
from some_table t
group by filename , status
having status = '<your-desired-status-here>'

Easy!

What I found works in the form is str_replace('&lt;br&gt;', PHP_EOL, $textarea);

In my case no shell was supported in container except sh. So, this worked like a charm

docker exec -it <container-name> sh

This error message can be very confusing and the solution can be surprisingly primitive.

In my case: Oracle stored procedure sends recordset to MS Excel via "Provider=OraOLEDB.Oracle;Data Source= ...etc" .

The problem was a number of decimal numbers in the Oracle data column sent to Excel 2010. When I used Oracle SQL query ROUND(grosssales_eur,2) AS grosssales_eur, it worked fine.

Use a list/dictionary or define your own class to encapsulate the stuff you're defining, but if you need all those variables you can do:

a = b = c = d = e = g = h = i = j = True
f = False

If anyone is interested, there is a jquery plugin called: jquery.matchHeight.js

https://github.com/liabru/jquery-match-height

matchHeight makes the height of all selected elements exactly equal. It handles many edge cases that cause similar plugins to fail.

For a row of cards, I use:

<div class="row match-height">

Then enable site-wide:

$('.row.match-height').each(function() {
   $(this).find('.card').not('.card .card').matchHeight(); // Not .card .card prevents collapsible cards from taking height
});

near the end of the parser function you missed a '}'

Try this. It's works for me well.

you can use

style="display:none"

Ex:

<asp:TextBox ID="txbProv" runat="server" style="display:none"></asp:TextBox>

I would focus on the differences between #table and @table. ##table is a global temporary table and for the record in over 10 years of using SQL Server I have yet to come across a valid use case. I'm sure that some exist but the nature of the object makes it highly unusable IMHO.

The response to @whiner by @marc_s is absolutely true: it is a prevalent myth that table variables always live in memory. It is actually quite common for a table variable to go to disk and operate just like a temp table.

Anyway I suggest reading up on the set of differences by following the links pointed out by @Astander. Most of the difference involve limitations on what you can't do with @table variables.

As for your regexp I guess it should be

^\+{0,2}([\-\. ])?(\(?\d{0,3}\))?([\-\. ])?\(?\d{0,3}\)?([\-\. ])?\d{3}([\-\. ])?\d{4}

But in general the presumption is not correct because one might enter something like ++44 20 1234 56789 or +44 (0) 1234 567890 it is better to do something like this

var phone = document.forms["myForm"]["phone"].value;
var phoneNum = phone.replace(/[^\d]/g, '');
if(phoneNum.length > 6 && phoneNum.length < 11) {  return true;  }

this will assure that entered value has 7 to 10 figures nevertheless what the formatting is. But you have to think about max length for number might be more than 10 as in the sample above.

Take care to strip out newlines from any string you pass to setData(). Otherwise an exception gets thrown.

Also note that even if you do that, then subsequently get that data again using getData(), CKEditor puts the line breaks back in.

Create a migration file

rails generate migration add_references_to_uploads user:references

Default foreign key name

This would create a user_id column in uploads table as a foreign key

class AddReferencesToUploads < ActiveRecord::Migration[5.2]
  def change
    add_reference :uploads, :user, foreign_key: true
  end
end

user model:

class User < ApplicationRecord
  has_many :uploads
end

upload model:

class Upload < ApplicationRecord
  belongs_to :user
end

Customize foreign key name:

add_reference :uploads, :author, references: :user, foreign_key: true

This would create an author_id column in the uploads tables as the foreign key.

user model:

class User < ApplicationRecord
  has_many :uploads, foreign_key: 'author_id'
end

upload model:

class Upload < ApplicationRecord
  belongs_to :user
end

This solution works for me right now. Maybe it is usefull to someone. Please excuse all the redundancy.

This is how I solved the problem The menu closes a few seconds after mouse out (that if hover didn't fire),

//Set timer switch
$setM_swith=0;

$(function(){
    $(".navbar-nav li a").click(function(event) {
        if (!$(this).parent().hasClass('dropdown'))
            $(".navbar-collapse").collapse('hide');
    });
    $(".navbar-collapse").mouseleave(function(){
        $setM_swith=1;
        setTimeout(function(){ 
           if($setM_swith==1) {
             $(".navbar-collapse").collapse('hide');
             $setM_swith=0;} 
        }, 3000);
    });
    $(".navbar-collapse").mouseover(function() {
        $setM_swith=0;
    });
 });

It semi-depends though... mine is:

C:\Windows\Microsoft.NET\Framework\v2.0.50727\CONFIG

and

C:\Windows\Microsoft.NET\Framework64\v2.0.50727\CONFIG

If you're array structure will always be multi-dimensional in that exact fashion, then we can iterate through the elements like such:

$fh = fopen('somefile.csv', 'w') or die('Cannot open the file');

for( $i=0; $i<count($arr); $i++ ){
    $str = implode( ',', $arr[$i] );
    fwrite( $fh, $str );
    fwrite( $fh, "\n" );
}
fclose($fh);

That's one way to do it ... you could do it manually but this way is quicker and easier to understand and read.

Then you would manage your headers something what complex857 is doing to spit out the file. You could then delete the file using unlink() if you no longer needed it, or you could leave it on the server if you wished.

skip = OFFSET
$products = $art->products->skip(0)->take(10)->get(); //get first 10 rows
$products = $art->products->skip(10)->take(10)->get(); //get next 10 rows

From laravel doc 5.2 https://laravel.com/docs/5.2/queries#ordering-grouping-limit-and-offset

skip / take

To limit the number of results returned from the query, or to skip a given number of results in the query (OFFSET), you may use the skip and take methods:

$users = DB::table('users')->skip(10)->take(5)->get();

In laravel 5.3 you can write (https://laravel.com/docs/5.3/queries#ordering-grouping-limit-and-offset)

$products = $art->products->offset(0)->limit(10)->get(); 

The best way is:

    public interface IDeepClonable<T> where T : class
    {
        T DeepClone();
    }

    public class MyObj : IDeepClonable<MyObj>
    {
        public MyObj Clone()
        {
            var myObj = new MyObj();
            myObj._field1 = _field1;//value type
            myObj._field2 = _field2;//value type
            myObj._field3 = _field3;//value type

            if (_child != null)
            {
                myObj._child = _child.DeepClone(); //reference type .DeepClone() that does the same
            }

            int len = _array.Length;
            myObj._array = new MyObj[len]; // array / collection
            for (int i = 0; i < len; i++)
            {
                myObj._array[i] = _array[i];
            }

            return myObj;
        }

        private bool _field1;
        public bool Field1
        {
            get { return _field1; }
            set { _field1 = value; }
        }

        private int _field2;
        public int Property2
        {
            get { return _field2; }
            set { _field2 = value; }
        }

        private string _field3;
        public string Property3
        {
            get { return _field3; }
            set { _field3 = value; }
        }

        private MyObj _child;
        private MyObj Child
        {
            get { return _child; }
            set { _child = value; }
        }

        private MyObj[] _array = new MyObj[4];
    }

In regards to the question in your comment:

Assuming that you've previously bound your function to the click event of the radio button, add this to your $(document).ready function:

$('#[radioButtonOptionID]').click()

Without a parameter, that simulates the click event.

Starting with version 3.5.0 of Mockito and using the InlineMockMaker, you can now mock object constructions:

 try (MockedConstruction mocked = mockConstruction(A.class)) {
   A a = new A();
   when(a.check()).thenReturn("bar");
 }

Inside the try-with-resources construct all object constructions are returning a mock.

Use insert() to insert an element before a given position.

For instance, with

arr = ['A','B','C']
arr.insert(0,'D')

arr becomes ['D','A','B','C'] because D is inserted before the element at index 0.

Now, for

arr = ['A','B','C']
arr.insert(4,'D')

arr becomes ['A','B','C','D'] because D is inserted before the element at index 4 (which is 1 beyond the end of the array).

However, if you are looking to generate all permutations of an array, there are ways to do this already built into Python. The itertools package has a permutation generator.

Here's some example code:

import itertools
arr = ['A','B','C']
perms = itertools.permutations(arr)
for perm in perms:
    print perm

will print out

('A', 'B', 'C')
('A', 'C', 'B')
('B', 'A', 'C')
('B', 'C', 'A')
('C', 'A', 'B')
('C', 'B', 'A')

use enumerate:

>>> l = ['a', 'b', 'c', 'd']
>>> for index, val in enumerate(l):
...    print "%d: %s" % (index, val)
... 
0: a
1: b
2: c
3: d

One more way to select between dates in SQLite is to use the powerful strftime function:

SELECT * FROM test WHERE strftime('%Y-%m-%d', date) BETWEEN "11-01-2011" AND "11-08-2011"

These are equivalent according to https://sqlite.org/lang_datefunc.html:

date(...)

strftime('%Y-%m-%d', ...)

but if you want more choice, you have it.

When I've stumbled upon this problem I usually start looking at the places where I FreeAndNil() or just xxx := NIL; variables and the code after that.

When nothing else has helped I've added a Log() function to output messages from various suspect places during execution, and then later looked at that log to trace where in the code the access violation comes.

There are ofcourse many more elegant solutions available for tracing these violations, but if you do not have them at your disposal the old-fashioned trial & error method works fine.

For me only thing worked is removing the element containing my application name, path and binding info under </system.applicationHost> element in applicationhost file. To be found under C:\Users\yourUsername\Documents\IISExpress\config

Closed the the solution , deleted the bad site element , save the applicationhost file and close. Reopen the application/Website from Visual studio using Admin rights - Rebuilt and Run. Voila... A new port is auto assigned to your application which solves the purpose.

Can also be verified without running-- check the Properties window for the solution and URL will have new port number.

Here's another way to think about it. Suppose there were a name() function that returned the name of its argument. Given the following code:

def f(a):
    return a

b = "x"
c = b
d = f(c)

e = [f(b), f(c), f(d)]

What should name(e[2]) return, and why?

The limit of the length of an HTTP Get request is dependent on both the server and the client (browser) used, from 2kB - 8kB. The server should return 414 (Request-URI Too Long) status if an URI is longer than the server can handle.

Note Someone said that I could use state names instead of state values; in other words I could use xhr.readyState === xhr.DONE instead of xhr.readyState === 4 The problem is that Internet Explorer uses different state names so it's better to use state values.

it sometimes occurs when we use a custom adapter in any activity of fragment . and we return null object i.e null view so the activity gets confused which view to load , so that is why this exception occurs

shows the position where to change the view

try use CMAKE_GENERATOR_PLATFORM

e.g.

// x86
cmake -DCMAKE_GENERATOR_PLATFORM=x86 . 

// x64
cmake -DCMAKE_GENERATOR_PLATFORM=x64 . 

function pageLoad() {
    console.log('pageLoad');
    $(document).ready(function () {
        alert("hi");
    });
};

its the ScriptManager ajax making the problem use pageLoad() instead

I had just upgraded to VS 2013 from VS 2012 and the current user identity (HttpContext.User.Identity) was coming through as anonymous.

I tried changing the IIS express applicationhost.config, no difference.

The solution was to look at the properties of the web project, hit F4 to get the project properties when you have the top level of the project selected. Do not right click on the project and select properties, this is something entirely different.

There are no gotchas. The default construction of std::string is "". But you cannot compare a string to NULL. The closest you can get is to check whether the string is empty or not, using the std::string::empty method..

This is my amended attempt (with a string passed in to function instead of a date object):

function calculateAge(dobString) {
    var dob = new Date(dobString);
    var currentDate = new Date();
    var currentYear = currentDate.getFullYear();
    var birthdayThisYear = new Date(currentYear, dob.getMonth(), dob.getDate());
    var age = currentYear - dob.getFullYear();

    if(birthdayThisYear > currentDate) {
        age--;
    }

    return age;
}

And usage:

console.log(calculateAge('1980-01-01'));

Let me show you a little trick.

As Arkanciscan said, you can use CSS3 transitions. But his solution looks different from the original tag.

What you really need to do is this:

  }_x000D_

When choosing the "best" approach, a more important consideration than speed might be the maintainability and correctness of your code. If so, SQL_CALC_FOUND_ROWS is preferable because you only need to maintain a single query. Using a single query completely precludes the possibility of a subtle difference between the main and count queries, which may lead to an inaccurate COUNT.

import string 

sentence = "I     am having  a   very  nice  23!@$      day. "
# Remove all punctuations
sentence = sentence.translate(str.maketrans('', '', string.punctuation))
# Remove all numbers"
sentence = ''.join([word for word in sentence if not word.isdigit()])
count = 0;
for index in range(len(sentence)-1) :
    if sentence[index+1].isspace() and not sentence[index].isspace():
        count += 1 
print(count)

delay does not work on none queue functions, so we should use setTimeout().

And you don't need to separate things. All you need to do is including everything in a setTimeOut method:

setTimeout(function () {
    $("#div").addClass("error").delay(1000).removeClass("error");
}, 1000);

Email address validation is not as easy as it might seem. It's actually theoretically impossible to fully validate an email address using just a regular expression.

You need "VT-x supported processor" at least to run Android emulator with Hardware acceleration.

If you have enabled or installed "Hyper-V" in your windows 8 then please remove it and disable the "Hyper threading" and enable "Virtualization".

ConfigurationSettings.AppSettings is obsolete, you should use ConfigurationManager.AppSettings instead (you will need to add a reference to System.Configuration)

int value = Int32.Parse(ConfigurationManager.AppSettings["StartingMonthColumn"]);

If you still have problems reading in your app settings then check that your app.config file is named correctly. Specifically, it should be named according to the executing assembly i.e. MyApp.exe.config, and should reside in the same directory as MyApp.exe.

To remove a project, you have to be the owner of this project, or the administrator of gitlab. Otherwise you can only see "rename project" but no "remove project".

NOTE THAT: the creator project is NOT always the owner of the project. If the project is in a project-group, and the project-group is created by another one, then the owner is the creator of the project-group by default.

You can find the owner's name of the project in the page Settings -> Members.

I don't think anyone has mentioned the fact that much more effort has been put into C compilers than any other compiler, with perhaps the exception of Java.

C is extremely optimize-able for many of the reasons already stated - more than almost any other language. So if the same amount of effort is put into other language compilers, C will probably still come out on top.

I think there is at least one candidate language that with effort could be optimized better than C and thus we could see implementations that produce faster binaries. I'm thinking of digital mars D because the creator took care to build a language that could potentially be better optimized than C. There may be other languages that have this possibility. However I cannot imagine that any language will have compilers more than just a few percent faster than the best C compilers. I would love to be wrong.

I think the real "low hanging fruit" will be in languages that are designed to be EASY for humans to optimize. A skilled programmer can make any language go faster - but sometimes you have to do ridiculous things or use unnatural constructs to make this happen. Although it will always take effort, a good language should produce relatively fast code without having to obsess over exactly how the program is written.

It's also important (at least to me) that the worst case code tends to be fast. There are numerous "proofs" on the web that Java is as fast or faster than C, but that is based on cherry picking examples. I'm not big fan of C, but I know that ANYTHING I write in C is going to run well. With Java it will "probably" run within 15% of the speed, usually within 25% but in some cases it can be far worse. Any cases where it's just as fast or within a couple of percent are usually due to most of the time being spent in the library code which is heavily optimized C anyway.

create a filter.js and you can make this as reusable

angular.module('yourmodule').filter('date', function($filter)
{
    return function(input)
    {
        if(input == null){ return ""; }
        var _date = $filter('date')(new Date(input), 'dd/MM/yyyy');
        return _date.toUpperCase();
    };
});

view

<span>{{ d.time | date }}</span>

or in controller

var filterdatetime = $filter('date')( yourdate );

Date filtering and formatting in Angular js.

Use strftime in the standard POSIX module. The arguments to strftime in Perl’s binding were designed to align with the return values from localtime and gmtime. Compare

strftime(fmt, sec, min, hour, mday, mon, year, wday = -1, yday = -1, isdst = -1)

with

my          ($sec,$min,$hour,$mday,$mon,$year,$wday,     $yday,     $isdst) = gmtime(time);

Example command-line use is

$ perl -MPOSIX -le 'print strftime "%F %T", localtime $^T'

or from a source file as in

use POSIX;

print strftime "%F %T", localtime time;

Some systems do not support the %F and %T shorthands, so you will have to be explicit with

print strftime "%Y-%m-%d %H:%M:%S", localtime time;

or

print strftime "%Y-%m-%d %H:%M:%S", gmtime time;

Note that time returns the current time when called whereas $^T is fixed to the time when your program started. With gmtime, the return value is the current time in GMT. Retrieve time in your local timezone with localtime.

Similar to Chris Marasti-Georg's example, instead using inline javascript. Essentially add onkeypress to the fields you want the enter key to work with. This example acts on the password field.

<html>
<head><title>title</title></head>
<body>
  <form action="" method="get">
  Name: <input type="text" name="name"/><br/>
  Pwd: <input type="password" name="password" onkeypress="if(event.keyCode==13) {javascript:form.submit();}" /><br/>
  <input type="submit" onClick="javascript:form.submit();"/>
</form>
</body>
</html>

When you concatenate strings, you need to allocate memory to store the result. The easiest to start with is String and &str:

fn main() {
    let mut owned_string: String = "hello ".to_owned();
    let borrowed_string: &str = "world";
    
    owned_string.push_str(borrowed_string);
    println!("{}", owned_string);
}

Here, we have an owned string that we can mutate. This is efficient as it potentially allows us to reuse the memory allocation. There's a similar case for String and String, as &String can be dereferenced as &str.

fn main() {
    let mut owned_string: String = "hello ".to_owned();
    let another_owned_string: String = "world".to_owned();
    
    owned_string.push_str(&another_owned_string);
    println!("{}", owned_string);
}

After this, another_owned_string is untouched (note no mut qualifier). There's another variant that consumes the String but doesn't require it to be mutable. This is an implementation of the Add trait that takes a String as the left-hand side and a &str as the right-hand side:

fn main() {
    let owned_string: String = "hello ".to_owned();
    let borrowed_string: &str = "world";
    
    let new_owned_string = owned_string + borrowed_string;
    println!("{}", new_owned_string);
}

Note that owned_string is no longer accessible after the call to +.

What if we wanted to produce a new string, leaving both untouched? The simplest way is to use format!:

fn main() {
    let borrowed_string: &str = "hello ";
    let another_borrowed_string: &str = "world";
    
    let together = format!("{}{}", borrowed_string, another_borrowed_string);

    // After https://rust-lang.github.io/rfcs/2795-format-args-implicit-identifiers.html
    // let together = format!("{borrowed_string}{another_borrowed_string}");

    println!("{}", together);
}

Note that both input variables are immutable, so we know that they aren't touched. If we wanted to do the same thing for any combination of String, we can use the fact that String also can be formatted:

fn main() {
    let owned_string: String = "hello ".to_owned();
    let another_owned_string: String = "world".to_owned();
    
    let together = format!("{}{}", owned_string, another_owned_string);

    // After https://rust-lang.github.io/rfcs/2795-format-args-implicit-identifiers.html
    // let together = format!("{owned_string}{another_owned_string}");
    println!("{}", together);
}

You don't have to use format! though. You can clone one string and append the other string to the new string:

fn main() {
    let owned_string: String = "hello ".to_owned();
    let borrowed_string: &str = "world";
    
    let together = owned_string.clone() + borrowed_string;
    println!("{}", together);
}

Note - all of the type specification I did is redundant - the compiler can infer all the types in play here. I added them simply to be clear to people new to Rust, as I expect this question to be popular with that group!

java [ options ] -jar file.jar [ argument ... ]

Python integers don't have an inherent length or number of significant digits. If you want them to print a specific way, you need to convert them to a string. There are several ways you can do so that let you specify things like padding characters and minimum lengths.

To pad with zeros to a minimum of three characters, try:

length = 1
print(format(length, '03'))

Xcode 12 and iOS 14 update. I have try the previous options to opt-out dark mode and this sentence in the info.plist file is not working for me:

<key>UIUserInterfaceStyle</key>
<string>Light</string>

Now it is renamed to:

<key>Appearance</key>
<string>Light</string>

This setting will block all dark mode in the full app.

EDITED:

Fixed typo thank you to @sarah

I'm surprised how many answers here are just wrong. Echoing nothing into a file will fill the file with something like ECHO is ON, and trying to echo $nul into a file will literally place $nul into the file. Additionally for PowerShell, echoing $null into a file won't actually make a 0kb file, but something encoded as UCS-2 LE BOM, which can get messy if you need to make sure your files don't have a byte-order mark.

After testing all the answers here and referencing some similar ones, I can guarantee these will work per console shell. Just change FileName.FileExtension to the full or relative-path of the file you want to touch; thanks to Keith Russell for the COPY NUL FILE.EXT update:

CMD w/Timestamp Updates

copy NUL FileName.FileExtension

This will create a new file named whatever you placed instead of FileName.FileExtension with a size of 0 bytes. If the file already exists it will basically copy itself in-place to update the timestamp. I'd say this is more of a workaround than 1:1 functionality with touch but I don't know of any built-in tools for CMD that can accomplish updating a file's timestamp without changing any of its other content.

CMD w/out Timestamp Updates

if not exist FileName.FileExtension copy NUL FileName.FileExtension

Powershell w/Timestamp Updates

if (!(Test-Path FileName.FileExtension -PathType Leaf)) {New-Item FileName.FileExtension -Type file} else {(ls FileName.FileExtension ).LastWriteTime = Get-Date}

Yes, it will work in-console as a one-liner; no requirement to place it in a PowerShell script file.

PowerShell w/out Timestamp Updates

if (!(Test-Path FileName.FileExtension -PathType Leaf)) {New-Item FileName.FileExtension -Type file}

In my app, I had similar problem: 2 line of string and, eventually, add "..." if the string was too long. I used this code in xml file into textview tag:

android:maxLines="2"
android:ellipsize="end"
android:singleLine="false"

Well, you can just put multiple "where" clauses in directly, but I don't think you want to. Multiple "where" clauses ends up with a more restrictive filter - I think you want a less restrictive one. I think you really want:

DataTable tempData = (DataTable)grdUsageRecords.DataSource;
var query = from r in tempData.AsEnumerable()
            where r.Field<string>("UserName") != "XXXX" &&
                  r.Field<string>("UserName") != "YYYY"
            select r;

DataTable newDT = query.CopyToDataTable();

Note the && instead of ||. You want to select the row if the username isn't XXXX and the username isn't YYYY.

EDIT: If you have a whole collection, it's even easier. Suppose the collection is called ignoredUserNames:

DataTable tempData = (DataTable)grdUsageRecords.DataSource;
var query = from r in tempData.AsEnumerable()
            where !ignoredUserNames.Contains(r.Field<string>("UserName"))
            select r;

DataTable newDT = query.CopyToDataTable();

Ideally you'd want to make this a HashSet<string> to avoid the Contains call taking a long time, but if the collection is small enough it won't make much odds.

function submitForm()
{
    if (testSubmit())
    {
        document.forms["myForm"].submit(); //first submit
        document.forms["myForm"].reset(); //and then reset the form values
    }
} </script> <body>
<form method="get" name="myForm">

    First Name: <input type="text" name="input1"/>
    <br/>
    Last Name: <input type="text" name="input2"/>
    <br/>
    <input type="button" value="Submit" onclick="submitForm()"/>
</form>

You can try HashSet<T>

silly way:

onclick="javascript:CapacityChart();"

You should read about discrete javascript, and use a frameworks bind method to bind callbacks to dom events.

switch is definitely preferred. It's easier to look at a switch's list of cases & know for sure what it is doing than to read the long if condition.

The duplication in the if condition is hard on the eyes. Suppose one of the == was written !=; would you notice? Or if one instance of 'numError' was written 'nmuError', which just happened to compile?

I'd generally prefer to use polymorphism instead of the switch, but without more details of the context, it's hard to say.

As for performance, your best bet is to use a profiler to measure the performance of your application in conditions that are similar to what you expect in the wild. Otherwise, you're probably optimizing in the wrong place and in the wrong way.

IF both POS_History_bim_data_*.zip and POS_History_bim_data_*.zip.trg exists in  Y:\ExternalData\RSIDest\ Folder then Delete File Y:\ExternalData\RSIDest\Target_slpos_unzip_done.dat

The <p> paragraph tag is meant for specifying paragraphs of text. If you don't want the text to start on a new line, I would suggest you're using the <p> tag incorrectly. Perhaps the <span> tag more closely fits what you want to achieve...?

you need to add a handler to the form submit event. In the handler you need to check for each text field, select element and password fields if there values are non empty.

$('form').submit(function() {
     var res = true;
     // here I am checking for textFields, password fields, and any 
     // drop down you may have in the form
     $("input[type='text'],select,input[type='password']",this).each(function() {
         if($(this).val().trim() == "") {
             res = false; 
         }
     })
     return res; // returning false will prevent the form from submitting.
});

The first four functions you list will work on vectors as well, with the exception that lower_wick needs to be adapted. Something like this,

def lower_wick_vec(o, l, c):
    min_oc = numpy.where(o > c, c, o)
    return min_oc - l

where o, l and c are vectors. You could do it this way instead which just takes the df as input and avoid using numpy, although it will be much slower:

def lower_wick_df(df):
    min_oc = df[['Open', 'Close']].min(axis=1)
    return min_oc - l

The other three will work on columns or vectors just as they are. Then you can finish off with

def is_hammer(df):
    lw = lower_wick_at_least_twice_real_body(df["Open"], df["Low"], df["Close"]) 
    cl = closed_in_top_half_of_range(df["High"], df["Low"], df["Close"])
    return cl & lw

Bit operators can perform set logic on boolean vectors, & for and, | for or etc. This is enough to completely vectorize the sample calculations you gave and should be relatively fast. You could probably speed up even more by temporarily working with the numpy arrays underlying the data while performing these calculations.

For the second part, I would recommend introducing a column indicating the pattern for each row and writing a family of functions which deal with each pattern. Then groupby the pattern and apply the appropriate function to each group.

Forgot to put the variable in the sql statement without quotations.

 $update_query = 
      "UPDATE db.tablename SET insert_time=NOW() WHERE username='" .$somename."'";

You can use a predefined "qualitative colormap" like this:

from matplotlib.cm import get_cmap

name = "Accent"
cmap = get_cmap(name)  # type: matplotlib.colors.ListedColormap
colors = cmap.colors  # type: list
axes.set_prop_cycle(color=colors)

Tested on matplotlib 3.0.3. See https://github.com/matplotlib/matplotlib/issues/10840 for discussion on why you can't call axes.set_prop_cycle(color=cmap).

A list of predefined qualititative colormaps is available at https://matplotlib.org/gallery/color/colormap_reference.html :

Use

.remove() of Interator or

Use

CopyOnWriteArrayList

Adding this to your code android:focusableInTouchMode="true" will make sure that your keypad doesn't appear on startup for your edittext box. You want to add this line to your linear layout that contains the EditTextBox. You should be able to play with this to solve both your problems. I have tested this. Simple solution.

ie: In your app_list_view.xml file

<LinearLayout 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:orientation="vertical" 
    android:focusableInTouchMode="true">
    <EditText 
        android:id="@+id/filter_edittext"       
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:hint="Search" 
        android:inputType="text" 
        android:maxLines="1"/>
    <ListView 
        android:id="@id/android:list" 
        android:layout_height="fill_parent"
        android:layout_weight="1.0" 
        android:layout_width="fill_parent" 
        android:focusable="true" 
        android:descendantFocusability="beforeDescendants"/>
</LinearLayout> 

------------------ EDIT: To Make keyboard appear on startup -----------------------

This is to make they Keyboard appear on the username edittextbox on startup. All I've done is added an empty Scrollview to the bottom of the .xml file, this puts the first edittext into focus and pops up the keyboard. I admit this is a hack, but I am assuming you just want this to work. I've tested it, and it works fine.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:paddingLeft="20dip"  
    android:paddingRight="20dip">
    <EditText 
        android:id="@+id/userName" 
        android:singleLine="true" 
        android:layout_width="fill_parent"  
        android:layout_height="wrap_content" 
        android:hint="Username"  
        android:imeOptions="actionDone" 
        android:inputType="text"
        android:maxLines="1"
       />
    <EditText 
        android:id="@+id/password" 
        android:password="true" 
        android:singleLine="true"  
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:hint="Password" />
    <ScrollView
        android:id="@+id/ScrollView01"  
        android:layout_height="fill_parent"   
        android:layout_width="fill_parent"> 
    </ScrollView>
</LinearLayout>

If you are looking for a more eloquent solution, I've found this question which might help you out, it is not as simple as the solution above but probably a better solution. I haven't tested it but it apparently works. I think it is similar to the solution you've tried which didn't work for you though.

Hope this is what you are looking for.

Cheers!

Actually, there are some situations which the throw statment will not preserve the StackTrace information. For example, in the code below:

try
{
  int i = 0;
  int j = 12 / i; // Line 47
  int k = j + 1;
}
catch
{
  // do something
  // ...
  throw; // Line 54
}

The StackTrace will indicate that line 54 raised the exception, although it was raised at line 47.

Unhandled Exception: System.DivideByZeroException: Attempted to divide by zero.
   at Program.WithThrowIncomplete() in Program.cs:line 54
   at Program.Main(String[] args) in Program.cs:line 106

In situations like the one described above, there are two options to preseve the original StackTrace:

Calling the Exception.InternalPreserveStackTrace

As it is a private method, it has to be invoked by using reflection:

private static void PreserveStackTrace(Exception exception)
{
  MethodInfo preserveStackTrace = typeof(Exception).GetMethod("InternalPreserveStackTrace",
    BindingFlags.Instance | BindingFlags.NonPublic);
  preserveStackTrace.Invoke(exception, null);
}

I has a disadvantage of relying on a private method to preserve the StackTrace information. It can be changed in future versions of .NET Framework. The code example above and proposed solution below was extracted from Fabrice MARGUERIE weblog.

Calling Exception.SetObjectData

The technique below was suggested by Anton Tykhyy as answer to In C#, how can I rethrow InnerException without losing stack trace question.

static void PreserveStackTrace (Exception e) 
{ 
  var ctx = new StreamingContext  (StreamingContextStates.CrossAppDomain) ; 
  var mgr = new ObjectManager     (null, ctx) ; 
  var si  = new SerializationInfo (e.GetType (), new FormatterConverter ()) ; 

  e.GetObjectData    (si, ctx)  ; 
  mgr.RegisterObject (e, 1, si) ; // prepare for SetObjectData 
  mgr.DoFixups       ()         ; // ObjectManager calls SetObjectData 

  // voila, e is unmodified save for _remoteStackTraceString 
} 

Although, it has the advantage of relying in public methods only it also depends on the following exception constructor (which some exceptions developed by 3rd parties do not implement):

protected Exception(
    SerializationInfo info,
    StreamingContext context
)

In my situation, I had to choose the first approach, because the exceptions raised by a 3rd-party library I was using didn't implement this constructor.

Cut can take several ranges in -f:

Columns up to 4 and from 7 onwards:

cut -f -4,7-

or for fields 1,2,5,6 and from 10 onwards:

cut -f 1,2,5,6,10-

etc

You can use "<pre>(.*?)</pre>", (replacing pre with whatever text you want) and extract the first group (for more specific instructions specify a language) but this assumes the simplistic notion that you have very simple and valid HTML.

As other commenters have suggested, if you're doing something complex, use a HTML parser.

You can use an infinite loop to achieve this:

while true
do
  read -p "Enter password" passwd
  case "$passwd" in
    <some good condition> ) break;;
  esac
done

You can chnage font size by ctrl + mousewheel.

OR

tools --> options --> environment --> font and color.

TL;DR:

{ withCredentials: true } or axios.defaults.withCredentials = true

From the axios documentation

withCredentials: false, // default

withCredentials indicates whether or not cross-site Access-Control requests should be made using credentials

If you pass { withCredentials: true } with your request it should work.

A better way would be setting withCredentials as true in axios.defaults

axios.defaults.withCredentials = true

I have had this issue also, and while -UseBasicParsing will work for some, if you actually need to interact with the dom it wont work. Try using a a group policy to stop the initial configuration window from ever appearing and powershell won't stop you anymore. See here https://wahlnetwork.com/2015/11/17/solving-the-first-launch-configuration-error-with-powershells-invoke-webrequest-cmdlet/

Took me just a few minutes once I found this page, once the GP is set, powershell will allow you through.
