The simplest is to just give the 'trans' (formerly 'formatter' argument the name of the log function:

m + geom_boxplot() + scale_y_continuous(trans='log10')

EDIT: Or if you don't like that, then either of these appears to give different but useful results:

m <- ggplot(diamonds, aes(y = price, x = color), log="y")
m + geom_boxplot() 
m <- ggplot(diamonds, aes(y = price, x = color), log10="y")
m + geom_boxplot()

EDIT2 & 3: Further experiments (after discarding the one that attempted successfully to put "$" signs in front of logged values):

fmtExpLg10 <- function(x) paste(round_any(10^x/1000, 0.01) , "K $", sep="")
ggplot(diamonds, aes(color, log10(price))) + 
  geom_boxplot() + 
  scale_y_continuous("Price, log10-scaling", trans = fmtExpLg10)

Note added mid 2017 in comment about package syntax change:

scale_y_continuous(formatter = 'log10') is now scale_y_continuous(trans = 'log10') (ggplot2 v2.2.1)

In case you use Spring Test try org.springframework.test.util.ReflectionTestUtils

 ReflectionTestUtils.setField(testObject, "person", mockedPerson);

Resolved for me by unselecting "Copy only when installed" on Build Phases->Embed Frameworks

If you want to take advantage of recent Python versions' async features, you can use aioftp (from the same family of libraries and developers as the more popular aiohttp library). Here is a code example taken from their client tutorial:

client = aioftp.Client()
await client.connect("ftp.server.com")
await client.login("user", "pass")
await client.download("tmp/test.py", "foo.py", write_into=True)

I'd use the RANK() function in a subselect and then just pull the row where rank = 1.

select person, language
from
( 
    select person, language, rank() over(order by language) as rank
    from table A
    group by person, language
)
where rank = 1

I had the same problem and unfortunately non of above answers worked for me . the solution that worked for me is :

right click on your startup project and select Properties - Debug and change "start external program: " to the correct path

Done!

I resolved it by setting the field blank:

Settings > Compiler > Java Compiler > Project bytecode version

Than IntelliJ uses the JDK default version.

Old question, but none of the answers satisfies me. One of my systems is running Ubuntu 12.04 LTS and for some reason there's no package python3-pip or python-pip for Python 3. So here is what I've done (all commands were executed as root):

• Install setuptools for Python3 in case you haven't.

  apt-get install python3-setuptools
  

  or

  aptitude install python3-setuptools
  

• With Python 2.4+ you can invoke easy_install with specific Python version by using python -m easy_install. So pip for Python 3 could be installed by:

  python3 -m easy_install pip
  

• That's it, you got pip for Python 3. Now just invoke pip with the specific version of Python to install package for Python 3. For example, with Python 3.2 installed on my system, I used:

  pip-3.2 install [package]
  

@str = "<span class=\"classname\">hello</span>" If in my view I do

<%raw @str %> The HTML source code is <span class=\"classname\">hello</span> where what I really want is <span class="classname">hello</span> (without the backslashes that were escaping the double >quotes). What's the best way to "unescape" those double quotes?

Solution: use double quotes inside of single quotes (or single inside of double) to avoid escaping with a backslash.

@str = '<span class="classname">hello</span>'
<%raw @str %>

in fact the Is is really good, since to the developpers, you may want to override the operator ==, to compare with the value. say you have a class A, operator == of A is to compare some of the field of A to the parameter. then you will be in trouble in c# to verify whether the object of A is null with following code,

    A a = new A();
...
    if (a != null)
it will totally wrong, you always need to use if((object)a != null)
but in vb.net you cannot write in this way, you always need to write
    if not a is nothing then
or
    if a isnot nothing then

which just as Christian said, vb.net does not 'expected' anything.

Here is an example of data binding with AngularJS, using an input field. I will explain later

HTML Code

<div ng-app="myApp" ng-controller="myCtrl" class="formInput">
     <input type="text" ng-model="watchInput" Placeholder="type something"/>
     <p>{{watchInput}}</p> 
</div>

AngularJS Code

myApp = angular.module ("myApp", []);
myApp.controller("myCtrl", ["$scope", function($scope){
  //Your Controller code goes here
}]);

As you can see in the example above, AngularJS uses ng-model to listen and watch what happens on HTML elements, especially on input fields. When something happens, do something. In our case, ng-model is bind to our view, using the mustache notation {{}}. Whatever is typed inside the input field is displayed on the screen instantly. And that's the beauty of data binding, using AngularJS in its simplest form.

Hope this helps.

See a working example here on Codepen

I'd explain parsing as the process of turning some kind of data into another kind of data.

In practice, for me this is almost always turning a string, or binary data, into a data structure inside my Program.

For example, turning

":Nick!User@Host PRIVMSG #channel :Hello!"

into (C)

struct irc_line {
    char *nick;
    char *user;
    char *host;
    char *command;
    char **arguments;
    char *message;
} sample = { "Nick", "User", "Host", "PRIVMSG", { "#channel" }, "Hello!" }

I would use .*. . matches any character, * signifies 0 or more occurrences. You might need a DOTALL switch to the regex to capture new lines with ..

Just remove the images using their IDs:

# docker rmi 5e2dfc857e73 d053e988f23d ...

I used @ddanone answear and added Ajax call.

$('#mydiv').on('scroll', function(){
  function infiniScroll(this);
});

function infiniScroll(mydiv){
console.log($(mydiv).scrollTop()+' + '+ $(mydiv).height()+' = '+ ($(mydiv).scrollTop() + $(mydiv).height())   +' _ '+ $(mydiv)[0].scrollHeight  );

if($(mydiv).scrollTop() + $(mydiv).height() == $(mydiv)[0].scrollHeight){
    console.log('bottom found');
    if(!$.active){ //if there is no ajax call active ( last ajax call waiting for results ) do again my ajax call
        myAjaxCall();
    }
}

}

One more way - mark such buttons with a CSS class and filter:

$('#myButton:not(.bound)').addClass('bound').bind('click',  onButtonClicked);

In recent jQuery versions replace bind with on:

$('#myButton:not(.bound)').addClass('bound').on('click',  onButtonClicked);

I get this error message and it mentions options.body

I had this originally

request.post({
    url: apiServerBaseUrl + '/v1/verify',
    body: {
        email: req.user.email
    }
});

I changed it to this:

request.post({
    url: apiServerBaseUrl + '/v1/verify',
    body: JSON.stringify({
        email: req.user.email
    })
});

and it seems to work now without the error message...seems like bug though.

I think this is the more official way to do it:

 request.post({
        url: apiServerBaseUrl + '/v1/verify',
        json: true,
        body: {
            email: req.user.email
        }
    });

Your markup should contain an additional attribute called ng-disabled whose value should be a condition or expression that would evaluate to be either true or false.

    <input data-ng-model="userInf.username"  class="span12 editEmail" 
       type="text"  placeholder="[email protected]"  
       pattern="[^@]+@[^@]+\.[a-zA-Z]{2,6}" 
       required 
       ng-disabled="{condition or expression}"
/>

And in the controller you may have some code that would affect the value of ng-disabled directive.

>>> import math
>>> import numpy as np
>>> import scipy
>>> math.pi == np.pi == scipy.pi
True

So it doesn't matter, they are all the same value.

The only reason all three modules provide a pi value is so if you are using just one of the three modules, you can conveniently have access to pi without having to import another module. They're not providing different values for pi.

If you spawn a Thread like so - myThread = Thread(target = function) - and then do myThread.start(); myThread.join(). When CTRL-C is initiated, the main thread doesn't exit because it is waiting on that blocking myThread.join() call. To fix this, simply put in a timeout on the .join() call. The timeout can be as long as you wish. If you want it to wait indefinitely, just put in a really long timeout, like 99999. It's also good practice to do myThread.daemon = True so all the threads exit when the main thread(non-daemon) exits.

Well, it doesn't get much better than that. Officially, you should use

dataGridView1.DataSource = typeof(List); 
dataGridView1.DataSource = itemStates;

It's still a "clear/reset source" kind of solution, but I have yet to find anything else that would reliably refresh the DGV data source.

window.location.href = "/somewhere/else";

DBContext.TestAddresses.Select(m => m.NAME).Distinct();

if you have multiple column do like this:

DBContext.TestAddresses.Select(m => new {m.NAME, m.ID}).Distinct();

In this example no duplicate CategoryId and no CategoryName i hope this will help you

Suppose there are multiple static synchronized methods (m1, m2, m3, m4) in a class, and suppose one thread is accessing m1, then no other thread at the same time can access any other static synchronized methods.

This did the job for me,

import org.apache.commons.lang.StringEscapeUtils;
...
String decodedXML= StringEscapeUtils.unescapeHtml(encodedXML);

or

import org.apache.commons.lang3.StringEscapeUtils;
...
String decodedXML= StringEscapeUtils.unescapeHtml4(encodedXML);

I guess its always better to use the lang3 for obvious reasons. Hope this helps :)

You need to include angular-route.js in your HTML:

<script src="angular-route.js">

For the sake of completeness a way with sed using regex and capture group:

md5=$(md5sum "${my_iso_file}" | sed -r 's:\\*([^ ]*).*:\1:')

The regulare expression is capturing everything in a group until a space is reached. To get capture group working you need to capture everything in sed. (More about sed and caputer groups here: https://stackoverflow.com/a/2778096/10926293)
As delimiter in sed i use colons because they are not valid in file paths and i don't have to escape the slashed in the filepath.

show all directry and sub directories

def dir():

Using a correlated query:

  SELECT t.id,
         t.count,
         (SELECT SUM(x.count)
            FROM TABLE x
           WHERE x.id <= t.id) AS cumulative_sum
    FROM TABLE t
ORDER BY t.id

Using MySQL variables:

  SELECT t.id,
         t.count,
         @running_total := @running_total + t.count AS cumulative_sum
    FROM TABLE t
    JOIN (SELECT @running_total := 0) r
ORDER BY t.id

Note:

• The JOIN (SELECT @running_total := 0) r is a cross join, and allows for variable declaration without requiring a separate SET command.
• The table alias, r, is required by MySQL for any subquery/derived table/inline view

Caveats:

• MySQL specific; not portable to other databases
• The ORDER BY is important; it ensures the order matches the OP and can have larger implications for more complicated variable usage (IE: psuedo ROW_NUMBER/RANK functionality, which MySQL lacks)

git fetch --all && git reset --hard origin/master

If you compile with optimizations enabled, then many variables will be removed; for example:

SomeType value = GetValue();
DoSomething(value);

here the local variable value would typically get removed, keeping the value on the stack instead - a bit like as if you had written:

DoSomething(GetValue());

Also, if a return value isn't used at all, then it will be dropped via "pop" (rather than stored in a local via "stloc", and again; the local will not exist).

Because of this, in such a build the debugger can't get the current value of value because it doesn't exist - it only exists for the brief instant between GetValue() and DoSomething(...).

So; if you want to debug... don't use a release build! or at least, disable optimizations while you debug.

I have same issue with IIS, i uninstalled IIS. Type in run services.msc, I see "wampapache64" service was not running, when I start it using right click it give me error.

I just used these steps.

1. Click on WAMP icon select Apache -> Service -> Remove Service

2. Click on Wamp icon select Apache -> Service -> Install Service

Got green Wamp icon :(

I've had success with express and editing the res.header. Mine matches yours pretty closely but I have a different Allow-Headers as noted below:

res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");

I'm also using Angular and Node/Express, but I don't have the headers called out in the Angular code only the node/express

You were close. This will work:

.image { position: relative; border: 1px solid black; width: 200px; height: 200px; }
.image img { max-width: 100%; max-height: 100%; }
.overlay { position: absolute; top: 0; left: 0; right:0; bottom:0; display: none; background-color: rgba(0,0,0,0.5); }
.image:hover .overlay { display: block; }

You needed to put the :hover on image, and make the .overlay cover the whole image by adding right:0; and bottom:0.

jsfiddle: http://jsfiddle.net/Zf5am/569/

To go one step further, I assume you want to do something with these dtypes. df.dtypes.to_dict() comes in handy.

my_type = 'float64' #<---

dtypes = dataframe.dtypes.to_dict()

for col_nam, typ in dtypes.items():
    if (typ != my_type): #<---
        raise ValueError(f"Yikes - `dataframe['{col_name}'].dtype == {typ}` not {my_type}")

You'll find that Pandas did a really good job comparing NumPy classes and user-provided strings. For example: even things like 'double' == dataframe['col_name'].dtype will succeed when .dtype==np.float64.

I made curl

I founded the curl project back in 1998, I wrote the initial curl version and I created libcurl. I've written more than half of all the 24,000 commits done in the source code repository up to this point in time. I'm still the lead developer of the project. To a large extent, curl is my baby.

I shipped the first version of curl as open source since I wanted to "give back" to the open source world that had given me so much code already. I had used so much open source and I wanted to be as cool as the other open source authors.

Thanks to it being open source, literally thousands of people have been able to help us out over the years and have improved the products, the documentation. the web site and just about every other detail around the project. curl and libcurl would never have become the products that they are today were they not open source. The list of contributors now surpass 1900 names and currently the list grows with a few hundred names per year.

Thanks to curl and libcurl being open source and liberally licensed, they were immediately adopted in numerous products and soon shipped by operating systems and Linux distributions everywhere thus getting a reach beyond imagination.

Thanks to them being "everywhere", available and liberally licensed they got adopted and used everywhere and by everyone. It created a defacto transfer library standard.

At an estimated six billion installations world wide, we can safely say that curl is the most widely used internet transfer library in the world. It simply would not have gone there had it not been open source. curl runs in billions of mobile phones, a billion Windows 10 installations, in a half a billion games and several hundred million TVs - and more.

Should I have released it with proprietary license instead and charged users for it? It never occured to me, and it wouldn't have worked because I would never had managed to create this kind of stellar project on my own. And projects and companies wouldn't have used it.

Why do I still work on curl?

Now, why do I and my fellow curl developers still continue to develop curl and give it away for free to the world?

1. I can't speak for my fellow project team members. We all participate in this for our own reasons.
2. I think it's still the right thing to do. I'm proud of what we've accomplished and I truly want to make the world a better place and I think curl does its little part in this.
3. There are still bugs to fix and features to add!
4. curl is free but my time is not. I still have a job and someone still has to pay someone for me to get paid every month so that I can put food on the table for my family. I charge customers and companies to help them with curl. You too can get my help for a fee, which then indirectly helps making sure that curl continues to evolve, remain free and the kick-ass product it is.
5. curl was my spare time project for twenty years before I started working with it full time. I've had great jobs and worked on awesome projects. I've been in a position of luxury where I could continue to work on curl on my spare time and keep shipping a quality product for free. My work on curl has given me friends, boosted my career and taken me to places I would not have been at otherwise.
6. I would not do it differently if I could back and do it again.

Am I proud of what we've done?

Yes. So insanely much.

But I'm not satisfied with this and I'm not just leaning back, happy with what we've done. I keep working on curl every single day, to improve, to fix bugs, to add features and to make sure curl keeps being the number one file transfer solution for the world even going forward.

We do mistakes along the way. We make the wrong decisions and sometimes we implement things in crazy ways. But to win in the end and to conquer the world is about patience and endurance and constantly going back and reconsidering previous decisions and correcting previous mistakes. To continuously iterate, polish off rough edges and gradually improve over time.

Never give in. Never stop. Fix bugs. Add features. Iterate. To the end of time.

For real?

Yeah. For real.

Do I ever get tired? Is it ever done?

Sure I get tired at times. Working on something every day for over twenty years isn't a paved downhill road. Sometimes there are obstacles. During times things are rough. Occasionally people are just as ugly and annoying as people can be.

But curl is my life's project and I have patience. I have thick skin and I don't give up easily. The tough times pass and most days are awesome. I get to hang out with awesome people and the reward is knowing that my code helps driving the Internet revolution everywhere is an ego boost above normal.

curl will never be "done" and so far I think work on curl is pretty much the most fun I can imagine. Yes, I still think so even after twenty years in the driver's seat. And as long as I think it's fun I intend to keep at it.

HTTP Is the Protocol handling the transmission of data over the internet.

If that transmission breaks for whatever reason the HTTP error codes tell you why it can't be sent to you.

The data being transmitted is not handled by HTTP Error codes. Only the method of transmission.

HTTP can't say 'Ok, this answer is gobbledigook, but here it is'. it just says 200 OK.

i.e : I've completed my job of getting it to you, the rest is up to you.

I know this has been answered already but I put it in words I can understand. sorry for any repetition.

Thank you Rob W for your answer.

I have been using this within a Cordova application to avoid having to load the API and so that I can easily control iframes which are loaded dynamically.

I always wanted the ability to be able to extract information from the iframe, such as the state (getPlayerState) and the time (getCurrentTime).

Rob W helped highlight how the API works using postMessage, but of course this only sends information in one direction, from our web page into the iframe. Accessing the getters requires us to listen for messages posted back to us from the iframe.

It took me some time to figure out how to tweak Rob W's answer to activate and listen to the messages returned by the iframe. I basically searched through the source code within the YouTube iframe until I found the code responsible for sending and receiving messages.

The key was changing the 'event' to 'listening', this basically gave access to all the methods which were designed to return values.

Below is my solution, please note that I have switched to 'listening' only when getters are requested, you can tweak the condition to include extra methods.

Note further that you can view all messages sent from the iframe by adding a console.log(e) to the window.onmessage. You will notice that once listening is activated you will receive constant updates which include the current time of the video. Calling getters such as getPlayerState will activate these constant updates but will only send a message involving the video state when the state has changed.

function callPlayer(iframe, func, args) {
    iframe=document.getElementById(iframe);
    var event = "command";
    if(func.indexOf('get')>-1){
        event = "listening";
    }

    if ( iframe&&iframe.src.indexOf('youtube.com/embed') !== -1) {
      iframe.contentWindow.postMessage( JSON.stringify({
          'event': event,
          'func': func,
          'args': args || []
      }), '*');
    }
}
window.onmessage = function(e){
    var data = JSON.parse(e.data);
    data = data.info;
    if(data.currentTime){
        console.log("The current time is "+data.currentTime);
    }
    if(data.playerState){
        console.log("The player state is "+data.playerState);
    }
}

you should divide hours by 24 not 11
like this:
select to_char(sysdate - 2/24, 'dd-mon-yyyy HH24') from dual

iWasRobbed's answer is great, except there is an AVCaptureSession running in the background all the time. On my iPhone 4s it takes about 12% CPU power according to Instrument so my app took about 1% battery in a minute. In other words if the device is prepared for AV capture it's not cheap.

Using the code below my app requires 0.187% a minute so the battery life is more than 5x longer.

This code works just fine on any device (tested on both 3GS (no flash) and 4s). Tested on 4.3 in simulator as well.

#import <AVFoundation/AVFoundation.h>

- (void) turnTorchOn:(BOOL)on {

    Class captureDeviceClass = NSClassFromString(@"AVCaptureDevice");
    if (captureDeviceClass != nil) {
        AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];
        if ([device hasTorch] && [device hasFlash]){

            [device lockForConfiguration:nil];
            if (on) {
                [device setTorchMode:AVCaptureTorchModeOn];
                [device setFlashMode:AVCaptureFlashModeOn];
                torchIsOn = YES;
            } else {
                [device setTorchMode:AVCaptureTorchModeOff];
                [device setFlashMode:AVCaptureFlashModeOff];
                torchIsOn = NO;            
            }
            [device unlockForConfiguration];
        }
    }
}

That TypeError only appears when you try to pass int() None (which is the only NoneType value, as far as I know). I would say that your real goal should not be to convert NoneType to int or str, but to figure out where/why you're getting None instead of a number as expected, and either fix it or handle the None properly.

you can use this :

getSupportActionBar().hide(); if it doesn't work try this one :

getActionBar().hide();

if above doesn't work try like this :

in your directory = res/values/style.xml , open style.xml -> there is attribute parent change to parent="Theme.AppCompat.Light.DarkActionBar"

if all of it doesn't work too. i don't know anymore. but for me it works.

An alternative would be instead of passing the parameters to the constructor you might have them as getter and setters and then in a @PostConstruct initialize the values as you want. In this case Spring will create the bean using the default constructor. An example is below

@Component
public class MyConstructorClass{

  String var;

  public void setVar(String var){
     this.var = var;
  }

  public void getVar(){
    return var;
  }

  @PostConstruct
  public void init(){
     setVar("var");
  }
...
}


@Service
public class MyBeanService{
  //field autowiring
  @Autowired
  MyConstructorClass myConstructorClass;

  ....
}

The problem with push command is that you your local and remote repository doesn't match. IF you initialize readme by default when creating new repository from git hub, then, master branch is automatically created. However, when you try to push that has no any branch. you cannot push... So, the best practice is to create repo without default readme initialization.

I tested the performance of FileInputStream vs. FileChannel for decoding base64 encoded files. In my experients I tested rather large file and traditional io was alway a bit faster than nio.

FileChannel might have had an advantage in prior versions of the jvm because of synchonization overhead in several io related classes, but modern jvm are pretty good at removing unneeded locks.

import pandas as pd

df = pd.DataFrame({'a' : [0,0,1], 'b' : [0,0,-1]})

temp = df.abs().sum(axis=1) == 0      
df = df.drop(temp)

Result:

>>> df
   a  b
2  1 -1

You cannot style a variable such as $ip['countryName']

You can only style elements like p,div, etc, or classes and ids.

If you want to style $ip['countryName'] there are several ways.

You can echo it within an element:

echo '<p id="style">'.$ip['countryName'].'</p>';
echo '<span id="style">'.$ip['countryName'].'</span>';
echo '<div id="style">'.$ip['countryName'].'</div>';

If you want to style both the variables the same style, then set a class like:

echo '<p class="style">'.$ip['cityName'].'</p>';
echo '<p class="style">'.$ip['countryName'].'</p>';

You could also embed the variables within your actual html rather than echoing them out within the code.

$city = $ip['cityName'];  
$country = $ip['countryName'];
?>
<div class="style"><?php echo $city ?></div>
<div class="style"><?php echo $country?></div>

If chmod does not work, you can try the following:

sudo nano /etc/php/7.x/fpm/pool.d/www.conf

Change the following paramaters:

user = www-data
group = www-data

To:

user = vagrant
group = vagrant

Remember to restart PHP FPM

sudo service php7.x-fpm restart

Basically you are doing it the right way. However, you should use an instance of the DataContext for querying (it's not obvious that DataContext is an instance or the type name from your query):

var result = (from a in new DataContext().Persons
              where a.Age > 18
              select new Person { Name = a.Name, Age = a.Age }).ToList();

Apparently, the Person class is your LINQ to SQL generated entity class. You should create your own class if you only want some of the columns:

class PersonInformation {
   public string Name {get;set;}
   public int Age {get;set;}
}

var result = (from a in new DataContext().Persons
              where a.Age > 18
              select new PersonInformation { Name = a.Name, Age = a.Age }).ToList();

You can freely swap var with List<PersonInformation> here without affecting anything (as this is what the compiler does).

Otherwise, if you are working locally with the query, I suggest considering an anonymous type:

var result = (from a in new DataContext().Persons
              where a.Age > 18
              select new { a.Name, a.Age }).ToList();

Note that in all of these cases, the result is statically typed (it's type is known at compile time). The latter type is a List of a compiler generated anonymous class similar to the PersonInformation class I wrote above. As of C# 3.0, there's no dynamic typing in the language.

UPDATE:

If you really want to return a List<Person> (which might or might not be the best thing to do), you can do this:

var result = from a in new DataContext().Persons
             where a.Age > 18
             select new { a.Name, a.Age };

List<Person> list = result.AsEnumerable()
                          .Select(o => new Person {
                                           Name = o.Name, 
                                           Age = o.Age
                          }).ToList();

You can merge the above statements too, but I separated them for clarity.

It's for both for Horizontal and for Vertical.

RecyclerView recyclerView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_test_recycler);
    recyclerView = (RecyclerView)findViewById(R.id.recyclerViewId);

    RecyclAdapter adapter = new RecyclAdapter();

    //Vertical RecyclerView
    RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getApplicationContext());
    recyclerView.setLayoutManager(mLayoutManager);

    //Horizontal RecyclerView
    //recyclerView.setLayoutManager(new LinearLayoutManager(getApplicationContext(),LinearLayoutManager.HORIZONTAL,false));

    recyclerView.setAdapter(adapter);

}

Above answers are correct, but if run script in other folder, there will be some problem.

For example, the a.sh and b.sh are in same folder, a include b with . ./b.sh to include.

When run script out of the folder, for example with xx/xx/xx/a.sh, file b.sh will not found: ./b.sh: No such file or directory.

I use

. $(dirname "$0")/b.sh

I have modified the above solutions and replaced Files.walk with Files.list. This also assumes the directory you are zipping only contains file and not any sub directories.

private void zipDirectory(Path dirPath) throws IOException {
        String zipFilePathStr = dirPath.toString() + ".zip";
        Path zipFilePath = Files.createFile(Paths.get(zipFilePathStr));

        try (ZipOutputStream zs = new ZipOutputStream(Files.newOutputStream(zipFilePath))) {
            Files.list(dirPath)
                .filter(filePath-> !Files.isDirectory(filePath))
                .forEach(filePath-> {
                    ZipEntry zipEntry = new ZipEntry(dirPath.relativize(filePath).toString());
                    try {
                        zs.putNextEntry(zipEntry);
                        Files.copy(filePath, zs);
                        zs.closeEntry();
                    }
                    catch (IOException e) {
                        System.err.println(e);
                    }
                });
        }
    }

My approach seems to work, but is probably naive. Tell me why it is wrong.

ARGs set during docker build are exposed by the history subcommand, so no go there. However, when running a container, environment variables given in the run command are available to the container, but are not part of the image.

So, in the Dockerfile, do setup that does not involve secret data. Set a CMD of something like /root/finish.sh. In the run command, use environmental variables to send secret data into the container. finish.sh uses the variables essentially to finish build tasks.

To make managing the secret data easier, put it into a file that is loaded by docker run with the --env-file switch. Of course, keep the file secret. .gitignore and such.

For me, finish.sh runs a Python program. It checks to make sure it hasn't run before, then finishes the setup (e.g., copies the database name into Django's settings.py).

The python shutil.copytree method its a mess. I've done one that works correctly:

def copydirectorykut(src, dst):
    os.chdir(dst)
    list=os.listdir(src)
    nom= src+'.txt'
    fitx= open(nom, 'w')

    for item in list:
        fitx.write("%s\n" % item)
    fitx.close()

    f = open(nom,'r')
    for line in f.readlines():
        if "." in line:
            shutil.copy(src+'/'+line[:-1],dst+'/'+line[:-1])
        else:
            if not os.path.exists(dst+'/'+line[:-1]):
                os.makedirs(dst+'/'+line[:-1])
                copydirectorykut(src+'/'+line[:-1],dst+'/'+line[:-1])
            copydirectorykut(src+'/'+line[:-1],dst+'/'+line[:-1])
    f.close()
    os.remove(nom)
    os.chdir('..')

Since $.browser is deprecated, here is an alternative solution:

/**
 * Returns the version of Internet Explorer or a -1
 * (indicating the use of another browser).
 */
function getInternetExplorerVersion()
{
    var rv = -1; // Return value assumes failure.

    if (navigator.appName == 'Microsoft Internet Explorer')
    {
        var ua = navigator.userAgent;
        var re  = new RegExp("MSIE ([0-9]{1,}[\.0-9]{0,})");
        if (re.exec(ua) != null)
            rv = parseFloat( RegExp.$1 );
    }

    return rv;
}

function checkVersion()
{
    var msg = "You're not using Internet Explorer.";
    var ver = getInternetExplorerVersion();

    if ( ver > -1 )
    {
        if ( ver >= 8.0 ) 
            msg = "You're using a recent copy of Internet Explorer."
        else
            msg = "You should upgrade your copy of Internet Explorer.";
    }

    alert( msg );
}

However, the reason that its deprecated is because jQuery wants you to use feature detection instead.

An example:

$("p").html("This frame uses the W3C box model: <span>" +
        jQuery.support.boxModel + "</span>");

And last but not least, the most reliable way to check IE versions:

// ----------------------------------------------------------
// A short snippet for detecting versions of IE in JavaScript
// without resorting to user-agent sniffing
// ----------------------------------------------------------
// If you're not in IE (or IE version is less than 5) then:
//     ie === undefined
// If you're in IE (>=5) then you can determine which version:
//     ie === 7; // IE7
// Thus, to detect IE:
//     if (ie) {}
// And to detect the version:
//     ie === 6 // IE6
//     ie > 7 // IE8, IE9 ...
//     ie < 9 // Anything less than IE9
// ----------------------------------------------------------

// UPDATE: Now using Live NodeList idea from @jdalton

var ie = (function(){

    var undef,
        v = 3,
        div = document.createElement('div'),
        all = div.getElementsByTagName('i');

    while (
        div.innerHTML = '<!--[if gt IE ' + (++v) + ']><i></i><![endif]-->',
        all[0]
    );

    return v > 4 ? v : undef;

}());

   class FormPage extends React.Component{
      constructor(props){
           super(props);
           this.state = {
             hidediv: false
           }
      }

     handleClick = (){
       this.setState({
          hidediv: true
        });
      }

      render(){
        return(
        <div>
          <div className="date-range" hidden = {this.state.hidediv}>
               <input type="submit" value="Search" onClick={this.handleClick} />
          </div>
          <div id="results" className="search-results" hidden = {!this.state.hidediv}>
                        Some Results
           </div>
        </div>
        );
      }
  }

You are using the FTP in an active mode.

Setting up the FTP in the active mode can be cumbersome nowadays due to firewalls and NATs.

It's likely because of your local firewall or NAT that the server was not able to connect back to your client to establish data transfer connection.

Or your client is not aware of its external IP address and provides an internal address instead to the server (in PORT command), which the server is obviously not able to use. But it should not be the case, as vsftpd by default rejects data transfer address not identical to source address of FTP control connection (the port_promiscuous directive).

See my article Network Configuration for Active Mode.

If possible, you should use a passive mode as it typically requires no additional setup on a client-side. That's also what the server suggested you by "Consider using PASV". The PASV is an FTP command used to enter the passive mode.

Unfortunately Windows FTP command-line client (the ftp.exe) does not support passive mode at all. It makes it pretty useless nowadays.

Use any other 3rd party Windows FTP command-line client instead. Most other support the passive mode.

For example WinSCP FTP client defaults to the passive mode and there's a guide available for converting Windows FTP script to WinSCP script.

(I'm the author of WinSCP)

lvalue means "left value" -- it should be assignable. You cannot change the value of text since it is an array, not a pointer.

Either declare it as char pointer (in this case it's better to declare it as const char*):

const char *text;
if(number == 2) 
    text = "awesome"; 
else 
    text = "you fail";

Or use strcpy:

char text[60];
if(number == 2) 
    strcpy(text, "awesome"); 
else 
    strcpy(text, "you fail");

Just tried it. the answer is -> out-of-range integer as a 2-byte value: 32768

You need to wrap the text in a div element and include the absolutely positioned element inside of it.

<div class="container">
    <div class="inner">
        <div class="full-height"></div>
        [Your text here]
    </div>
</div>

Css:

.inner: { position: relative; height: auto; }
.full-height: { height: 100%; }

Setting the inner div's position to relative makes the absolutely position elements inside of it base their position and height on it rather than on the .container div, which has a fixed height. Without the inner, relatively positioned div, the .full-height div will always calculate its dimensions and position based on .container.

(Linux/WSL at least) From the browser at bitbucket.org, create an empty repo with the same name as your local repo, follow the instructions proposed by bitbucket for importing a local repo (two commands to type).

pip install django-cors-headers

and then add it to your installed apps:

INSTALLED_APPS = (
    ...
    'corsheaders',
    ...
)

You will also need to add a middleware class to listen in on responses:

MIDDLEWARE_CLASSES = (
    ...
    'corsheaders.middleware.CorsMiddleware',  
    'django.middleware.common.CommonMiddleware',  
    ...
)

CORS_ORIGIN_ALLOW_ALL = True # If this is used then `CORS_ORIGIN_WHITELIST` will not have any effect
CORS_ALLOW_CREDENTIALS = True
CORS_ORIGIN_WHITELIST = [
    'http://localhost:3030',
] # If this is used, then not need to use `CORS_ORIGIN_ALLOW_ALL = True`
CORS_ORIGIN_REGEX_WHITELIST = [
    'http://localhost:3030',

In case there are many people using your vagrant file - you might want to set name dynamically. Below is the example how to do it using username from your HOST machine as the name of the box and hostname:

require 'etc'
vagrant_name = "yourProjectName-" + Etc.getlogin
Vagrant.configure("2") do |config|
  config.vm.box = "ubuntu/xenial64"
  config.vm.hostname = vagrant_name
  config.vm.provider "virtualbox" do |v|
    v.name = vagrant_name
  end
end

This is not valid TypeScript code. You can not have method invocations in the body of a class.

// INVALID CODE
export class AppComponent {
  public n: number = 1;
  setTimeout(function() {
    n = n + 10;
  }, 1000);
}

Instead move the setTimeout call to the constructor of the class. Additionally, use the arrow function => to gain access to this.

export class AppComponent {
  public n: number = 1;

  constructor() {
    setTimeout(() => {
      this.n = this.n + 10;
    }, 1000);
  }

}

In TypeScript, you can only refer to class properties or methods via this. That's why the arrow function => is important.

This might be helpful if you want a concise function that you can call from your main method, inside your class. You may still need to call int.Parse(toBinary(someint)) if you require a number instead of a string but I find this method work pretty well. Additionally, this can be adjusted to use a for loop instead of a do-while if you'd prefer.

    public static string toBinary(int base10)
    {
        string binary = "";
        do {
            binary = (base10 % 2) + binary;
            base10 /= 2;
        }
        while (base10 > 0);

        return binary;
    }

toBinary(10) returns the string "1010".

Calling object.paintComponent(g) is an error.

Instead this method is called automatically when the panel is created. The paintComponent() method can also be called explicitly by the repaint() method defined in Component class.

The effect of calling repaint() is that Swing automatically clears the graphic on the panel and executes the paintComponent method to redraw the graphics on this panel.

You can call this method using the resultSet and the column name having Number type. It will either return the Integer value, or null. There will be no zeros returned for empty value in the database

private Integer getIntWithNullCheck(ResultSet rset, String columnName) {
    try {
        Integer value = rset.getInt(columnName);
        return rset.wasNull() ? null : value;
    } catch (Exception e) {
        return null;
    }
}

If you know what are the useless warnings you usually encounter, you can filter them by message.

import warnings

#ignore by message
warnings.filterwarnings("ignore", message="divide by zero encountered in divide")

#part of the message is also okay
warnings.filterwarnings("ignore", message="divide by zero encountered") 
warnings.filterwarnings("ignore", message="invalid value encountered")

char variable = 'x';  // the variable is a char whose value is lowercase x

printf("<%c>", variable); // print it with angle brackets around the character

With that solution the only scrollbar in the page is on your contents section in the middle! In that section build your structure with a sidebar or whatever you want!

You can do that with that code here:

<div class="navTop">
<h1>Title</h1>
    <nav>Dynamic menu</nav>
</div>
<div class="container">
    <section>THE CONTENTS GOES HERE</section>
</div>
<footer class="bottomFooter">
    Footer
</footer>

With that css:

.navTop{
width:100%;
border:1px solid black;
float:left;
}
.container{
width:100%;
float:left;
overflow:scroll;
}
.bottomFooter{
float:left;
border:1px solid black;
width:100%;
}

And a bit of jquery:

$(document).ready(function() {
  function setHeight() {
    var top = $('.navTop').outerHeight();
    var bottom = $('footer').outerHeight();
    var totHeight = $(window).height();
    $('section').css({ 
      'height': totHeight - top - bottom + 'px'
    });
  }

  $(window).on('resize', function() { setHeight(); });
  setHeight();
});

Just (array) is missing in your code before the simplexml object:

...

$xml   = simplexml_load_string($string, 'SimpleXMLElement', LIBXML_NOCDATA);

$array = json_decode(json_encode((array)$xml), TRUE);
                                 ^^^^^^^

You can set TabLayout position using following functions

public void setTab(){
 tabLayout.setScrollPosition(YOUR_SCROLL_INDEX,0,true);
 tabLayout.setSelected(true);
}

From a little search, that I understand the file should be opened in universal newline mode, which you cannot directly do with a response content (I guess).

To finish the task, you can either save the downloaded content to a temporary file, or process it in memory.

Save as file:

import requests
import csv
import os

temp_file_name = 'temp_csv.csv'
url = 'http://url.to/file.csv'
download = requests.get(url)

with open(temp_file_name, 'w') as temp_file:
    temp_file.writelines(download.content)

with open(temp_file_name, 'rU') as temp_file:
    csv_reader = csv.reader(temp_file, dialect=csv.excel_tab)
    for line in csv_reader:
        print line

# delete the temp file after process
os.remove(temp_file_name)

In memory:

If you are using SQL Server 2005 (or greater) you might want to consider switching to NVARCHAR(MAX) in your table definition; TEXT, NTEXT, and IMAGE data types of SQL Server 2000 will be deprecated in future versions of SQL Server. SQL Server 2005 provides backward compatibility to data types, but you should probably be using VARCHAR(MAX), NVARCHAR(MAX), and VARBINARY(MAX) instead.

For the C-runtime go to the project settings, choose C/C++ then 'Code Generation'. Change the 'runtime library' setting to 'multithreaded' instead of 'multithreaded dll'.

If you are using any other libraries you may need to tell the linker to ignore the dynamically linked CRT explicitly.

First you should check how many commits you have:

git log

There are two status:

One is that there are only two commits:

For example:

commit A
commit B

(In this case, you can't use git rebase to do) you need to do following.

$ git reset --soft HEAD^1

$ git commit --amend

Another is that there are more than two commits; you want to merge commit C and D.

For example:

commit A
commit B
commit C
commit D

(under this condition, you can use git rebase)

git rebase -i B

And than use "squash" to do. The rest thins is very easy. If you still don't know, please read http://zerodie.github.io/blog/2012/01/19/git-rebase-i/

int a = fork(); 

Creates a duplicate process "clone?", which shares the execution stack. The difference between the parent and the child is the return value of the function.

The child getting 0 returned, and the parent getting the new pid.

Each time the addresses and the values of the stack variables are copied. The execution continues at the point it already got to in the code.

At each fork, only one value is modified - the return value from fork.

I know that this is an old question, but the ignore-unresolvable property was not working for me and I didn't know why.

The problem was that I needed an external resource (something like location="file:${CATALINA_HOME}/conf/db-override.properties") and the ignore-unresolvable="true" does not do the job in this case.

What one needs to do for ignoring a missing external resource is:

ignore-resource-not-found="true"

Just in case anyone else bumps into this.

Always show errors on a testing server. Never show errors on a production server.

Write a script to determine whether the page is on a local, testing, or live server, and set $state to "local", "testing", or "live". Then:

if( $state == "local" || $state == "testing" )
{
    ini_set( "display_errors", "1" );
    error_reporting( E_ALL & ~E_NOTICE );
}
else
{
    error_reporting( 0 );
}

The OSIV Anti-Pattern

Instead of letting the business layer decide how it’s best to fetch all the associations that are needed by the View layer, OSIV (Open Session in View) forces the Persistence Context to stay open so that the View layer can trigger the Proxy initialization, as illustrated by the following diagram.

• The OpenSessionInViewFilter calls the openSession method of the underlying SessionFactory and obtains a new Session.
• The Session is bound to the TransactionSynchronizationManager.
• The OpenSessionInViewFilter calls the doFilter of the javax.servlet.FilterChain object reference and the request is further processed
• The DispatcherServlet is called, and it routes the HTTP request to the underlying PostController.
• The PostController calls the PostService to get a list of Post entities.
• The PostService opens a new transaction, and the HibernateTransactionManager reuses the same Session that was opened by the OpenSessionInViewFilter.
• The PostDAO fetches the list of Post entities without initializing any lazy association.
• The PostService commits the underlying transaction, but the Session is not closed because it was opened externally.
• The DispatcherServlet starts rendering the UI, which, in turn, navigates the lazy associations and triggers their initialization.
• The OpenSessionInViewFilter can close the Session, and the underlying database connection is released as well.

At first glance, this might not look like a terrible thing to do, but, once you view it from a database perspective, a series of flaws start to become more obvious.

The service layer opens and closes a database transaction, but afterward, there is no explicit transaction going on. For this reason, every additional statement issued from the UI rendering phase is executed in auto-commit mode. Auto-commit puts pressure on the database server because each transaction issues a commit at end, which can trigger a transaction log flush to disk. One optimization would be to mark the Connection as read-only which would allow the database server to avoid writing to the transaction log.

There is no separation of concerns anymore because statements are generated both by the service layer and by the UI rendering process. Writing integration tests that assert the number of statements being generated requires going through all layers (web, service, DAO) while having the application deployed on a web container. Even when using an in-memory database (e.g. HSQLDB) and a lightweight webserver (e.g. Jetty), these integration tests are going to be slower to execute than if layers were separated and the back-end integration tests used the database, while the front-end integration tests were mocking the service layer altogether.

The UI layer is limited to navigating associations which can, in turn, trigger N+1 query problems. Although Hibernate offers @BatchSize for fetching associations in batches, and FetchMode.SUBSELECT to cope with this scenario, the annotations are affecting the default fetch plan, so they get applied to every business use case. For this reason, a data access layer query is much more suitable because it can be tailored to the current use case data fetch requirements.

Last but not least, the database connection is held throughout the UI rendering phase which increases connection lease time and limits the overall transaction throughput due to congestion on the database connection pool. The more the connection is held, the more other concurrent requests are going to wait to get a connection from the pool.

Spring Boot and OSIV

Unfortunately, OSIV (Open Session in View) is enabled by default in Spring Boot, and OSIV is really a bad idea from a performance and scalability perspective.

So, make sure that in the application.properties configuration file, you have the following entry:

spring.jpa.open-in-view=false

This will disable OSIV so that you can handle the LazyInitializationException the right way.

Starting with version 2.0, Spring Boot issues a warning when OSIV is enabled by default, so you can discover this problem long before it affects a production system.

How can I properly handle 404 in ASP.NET MVC?

declare your date column as NOT NULL, but without a default. Then add this trigger:

USE `ddb`;
DELIMITER $$
CREATE TRIGGER `default_date` BEFORE INSERT ON `dtable` FOR EACH ROW
if ( isnull(new.query_date) ) then
 set new.query_date=curdate();
end if;

Short and simple implementation in Kotlin, with nullable support:

Add methods to Parcel

fun Parcel.writeBoolean(flag: Boolean?) {
    when(flag) {
        true -> writeInt(1)
        false -> writeInt(0)
        else -> writeInt(-1)
    }
}

fun Parcel.readBoolean(): Boolean? {
    return when(readInt()) {
        1 -> true
        0 -> false
        else -> null
    }
}

And use it:

parcel.writeBoolean(isUserActive)

parcel.readBoolean()        // For true, false, null
parcel.readBoolean()!!      // For only true and false

how about:

scope.$watch(function() { 
   return { 
      a: thing-one, 
      b: thing-two, 
      c: red-fish, 
      d: blue-fish 
   }; 
}, listener...);

Have you taken a look at ExpandoObject?

see: http://blogs.msdn.com/b/csharpfaq/archive/2009/10/01/dynamic-in-c-4-0-introducing-the-expandoobject.aspx

From MSDN:

The ExpandoObject class enables you to add and delete members of its instances at run time and also to set and get values of these members. This class supports dynamic binding, which enables you to use standard syntax like sampleObject.sampleMember instead of more complex syntax like sampleObject.GetAttribute("sampleMember").

Allowing you to do cool things like:

dynamic dynObject = new ExpandoObject();
dynObject.SomeDynamicProperty = "Hello!";
dynObject.SomeDynamicAction = (msg) =>
    {
        Console.WriteLine(msg);
    };

dynObject.SomeDynamicAction(dynObject.SomeDynamicProperty);

Based on your actual code you may be more interested in:

public static dynamic GetDynamicObject(Dictionary<string, object> properties)
{
    return new MyDynObject(properties);
}

public sealed class MyDynObject : DynamicObject
{
    private readonly Dictionary<string, object> _properties;

    public MyDynObject(Dictionary<string, object> properties)
    {
        _properties = properties;
    }

    public override IEnumerable<string> GetDynamicMemberNames()
    {
        return _properties.Keys;
    }

    public override bool TryGetMember(GetMemberBinder binder, out object result)
    {
        if (_properties.ContainsKey(binder.Name))
        {
            result = _properties[binder.Name];
            return true;
        }
        else
        {
            result = null;
            return false;
        }
    }

    public override bool TrySetMember(SetMemberBinder binder, object value)
    {
        if (_properties.ContainsKey(binder.Name))
        {
            _properties[binder.Name] = value;
            return true;
        }
        else
        {
            return false;
        }
    }
}

That way you just need:

var dyn = GetDynamicObject(new Dictionary<string, object>()
    {
        {"prop1", 12},
    });

Console.WriteLine(dyn.prop1);
dyn.prop1 = 150;

Deriving from DynamicObject allows you to come up with your own strategy for handling these dynamic member requests, beware there be monsters here: the compiler will not be able to verify a lot of your dynamic calls and you won't get intellisense, so just keep that in mind.

The clue is in the name

Services and factories are similar to one another. Both will yield a singleton object that can be injected into other objects, and so are often used interchangeably.

They are intended to be used semantically to implement different design patterns.

Services are for implementing a service pattern

A service pattern is one in which your application is broken into logically consistent units of functionality. An example might be an API accessor, or a set of business logic.

This is especially important in Angular because Angular models are typically just JSON objects pulled from a server, and so we need somewhere to put our business logic.

Here is a Github service for example. It knows how to talk to Github. It knows about urls and methods. We can inject it into a controller, and it will generate and return a promise.

(function() {
  var base = "https://api.github.com";

  angular.module('github', [])
    .service('githubService', function( $http ) {
      this.getEvents: function() {
        var url = [
          base,
          '/events',
          '?callback=JSON_CALLBACK'
        ].join('');
        return $http.jsonp(url);
      }
    });
  )();

Factories implement a factory pattern

Factories, on the other hand are intended to implement a factory pattern. A factory pattern in one in which we use a factory function to generate an object. Typically we might use this for building models. Here is a factory which returns an Author constructor:

angular.module('user', [])
  .factory('User', function($resource) {
    var url = 'http://simple-api.herokuapp.com/api/v1/authors/:id'
    return $resource(url);
  })

We would make use of this like so:

angular.module('app', ['user'])
  .controller('authorController', function($scope, User) {
    $scope.user = new User();
  })

Note that factories also return singletons.

Factories can return a constructor

Because a factory simply returns an object, it can return any type of object you like, including a constructor function, as we see above.

Factories return an object; services are newable

Another technical difference is in the way services and factories are composed. A service function will be newed to generate the object. A factory function will be called and will return the object.

• Services are newable constructors.
• Factories are simply called and return an object.

This means that in a service, we append to "this" which, in the context of a constructor, will point to the object under construction.

To illustrate this, here is the same simple object created using a service and a factory:

angular.module('app', [])
  .service('helloService', function() {
    this.sayHello = function() {
      return "Hello!";
    }
  })
  .factory('helloFactory', function() {
    return {
      sayHello: function() {
        return "Hello!";
      }
    }
  });

while (rs.next())
{
  if (f.exists() && !f.isDirectory())
    continue;

  //proceed
}

Documentation here, and I'll use the Frankfurt region as an example.

There are 2 different URL styles:

• Virtual host style: https://BUCKET.s3.amazonaws.com/FILE
• Path style: https://s3.eu-central-1.amazonaws.com/BUCKET/FILE

But this url does not work:

• https://s3.amazonaws.com/BUCKET/FILE

The message is explicit: The bucket you are attempting to access must be addressed using the specified endpoint. Please send all future requests to this endpoint.

I may be talking about another problem because I'm not getting NoSuchKey error but I suspect the error message has been made clearer over time.

First I recommend you to read following book;

Algorithms (4th Edition)

Here is some functions and their expected complexities. Numbers are indicating statement execution frequencies.

Following Big-O Complexity Chart also taken from bigocheatsheet

Lastly very simple showcase there is shows how it is calculated;

Anatomy of a program’s statement execution frequencies.

Analyzing the running time of a program (example).

Well first of all there's no such thing as "arrays" in Python, Python uses lists and that does make a difference, I suggest you use NumPy which is a pretty good library for Python and it adds a lot of Matlab-like functionality.You can get started here Numpy for Matlab users

Primarily what that means is that there are too many concurrent requests and further that they exceed the default 1000 queued requests. That is there are 1000 or more queued requests to your website.

This could happen (assuming there are no faults in your app) if there are long running tasks and as a result the Request queue is backed up.

Depending on how the application pool has been set up you may see this kind of thing. Typically, the app pool's Process Model has an item called Maximum Worker Processes. By default this is 1. If you set it to more than 1 (typically up to a max of the number of cores on the hardware) you may not see this happen.

Just to note that unless the site is extremely busy you should not see this. If you do, it's really pointing to long running tasks

This is a bad way of doing it, but it worked for me when trying to interpret escaped octals passed in a string argument.

input_string = eval('b"' + sys.argv[1] + '"')

It's worth mentioning that there is a difference between eval and ast.literal_eval (eval being way more unsafe). See Using python's eval() vs. ast.literal_eval()?

You use attach without detach - every time you do it new call to attach masks objects attached before (they contain the same names). Either use detach or do not use attach at all. Nice discussion and tips are here.

I have noticed that when intellisence doesn't work for an object there is usually an error somewhere in the class above line you are working on.

The other option is that you didn't instantiated the FileUpload object as an instance variable. make sure the code:

FileUpload fileUpload = new FileUpload();

is not inside a function in your code behind.

In Java create the pattern with Pattern p = Pattern.compile("^\\w{14}$"); for further information see the javadoc

Set up a virtualenv:

% curl -kLso /tmp/get-pip.py https://bootstrap.pypa.io/get-pip.py 
% sudo python /tmp/get-pip.py

These commands install pip into the global site-packages directory.

% sudo pip install virtualenv

and ditto for virtualenv:

% mkdir -p ~/.virtualenvs

I like my virtualenvs under one tree in my home directory called .virtualenvs

% virtualenv ~/.virtualenvs/lxmltest

Creates a virtualenv.

% . ~/.virtualenvs/lxmltest/bin/activate

Removes the need to specify the full path to pip/python in this virtualenv.

% pip install lxml

Alternatively execute ~/.virtualenvs/lxmltest/bin/pip install lxml if you chose not to follow the previous step. Note, I'm not sure how far along you are, so some of these steps can be safely skipped. Of course, if you mess something up, you can always rm -Rf ~/.virtualenvs/lxmltest and start again from a new virtualenv.

Here is the proper solution. You should use jquery datepicker everywhere

  <script>
  $( function() {
    $( ".simple_date" ).datepicker();
  } );
  </script>

I just figure it out lately on how easy it is to make your bootstrap v3.1.1 being non-responsive. This includes navbars to not to collpase. I don't know if everyone knows this but I'd like to share it.

Two Steps to a Non-responsive Bootsrap v3.1.1

First, create a css file name it as non-responsive.css. Make sure to append it to your themes or link right after the bootstrap css files.

Second, paste this code to your non-responsive.css:

/* Template-specific stuff
 *
 * Customizations just for the template; these are not necessary for anything
 * with disabling the responsiveness.
 */

/* Account for fixed navbar */
body {
  min-width: 970px;
  padding-top: 70px;
  padding-bottom: 30px;
}

/* Finesse the page header spacing */
.page-header {
  margin-bottom: 30px;
}
.page-header .lead {
  margin-bottom: 10px;
}


/* Non-responsive overrides
 *
 * Utilitze the following CSS to disable the responsive-ness of the container,
 * grid system, and navbar.
 */

/* Reset the container */
.container {
  width: 970px;
  max-width: none !important;
}

/* Demonstrate the grids */
.col-xs-4 {
  padding-top: 15px;
  padding-bottom: 15px;
  background-color: #eee;
  background-color: rgba(86,61,124,.15);
  border: 1px solid #ddd;
  border: 1px solid rgba(86,61,124,.2);
}

.container .navbar-header,
.container .navbar-collapse {
  margin-right: 0;
  margin-left: 0;
}

/* Always float the navbar header */
.navbar-header {
  float: left;
}

/* Undo the collapsing navbar */
.navbar-collapse {
  display: block !important;
  height: auto !important;
  padding-bottom: 0;
  overflow: visible !important;
}

.navbar-toggle {
  display: none;
}
.navbar-collapse {
  border-top: 0;
}

.navbar-brand {
  margin-left: -15px;
}

/* Always apply the floated nav */
.navbar-nav {
  float: left;
  margin: 0;
}
.navbar-nav > li {
  float: left;
}
.navbar-nav > li > a {
  padding: 15px;
}

/* Redeclare since we override the float above */
.navbar-nav.navbar-right {
  float: right;
}

/* Undo custom dropdowns */
.navbar .navbar-nav .open .dropdown-menu {
  position: absolute;
  float: left;
  background-color: #fff;
  border: 1px solid #ccc;
  border: 1px solid rgba(0, 0, 0, .15);
  border-width: 0 1px 1px;
  border-radius: 0 0 4px 4px;
  -webkit-box-shadow: 0 6px 12px rgba(0, 0, 0, .175);
          box-shadow: 0 6px 12px rgba(0, 0, 0, .175);
}
.navbar-default .navbar-nav .open .dropdown-menu > li > a {
  color: #333;
}
.navbar .navbar-nav .open .dropdown-menu > li > a:hover,
.navbar .navbar-nav .open .dropdown-menu > li > a:focus,
.navbar .navbar-nav .open .dropdown-menu > .active > a,
.navbar .navbar-nav .open .dropdown-menu > .active > a:hover,
.navbar .navbar-nav .open .dropdown-menu > .active > a:focus {
  color: #fff !important;
  background-color: #428bca !important;
}
.navbar .navbar-nav .open .dropdown-menu > .disabled > a,
.navbar .navbar-nav .open .dropdown-menu > .disabled > a:hover,
.navbar .navbar-nav .open .dropdown-menu > .disabled > a:focus {
  color: #999 !important;
  background-color: transparent !important;
}

That's all and Enjoy..^^

I used git svn, and had this problem for one file. Using ls-tree for each ancestor of the file, I noticed that one had 2 subfolders - Submit and submit. Since I was on Windows, they couldn't both be checked out, causing this issue.

The solution was to delete one of them directly from TortoiseSVN Repo-browser, then to run git svn fetch followed by git reset --hard origin/trunk.

How about this:

When the page first loads, do this:

var myTable = document.getElementById("myTable");
myTable.oldHTML=myTable.innerHTML;

Then when you want to clear the table:

myTable.innerHTML=myTable.oldHTML;

The result will be your header row(s) if that's all you started with, the performance is dramatically faster than looping.

In following code, we don't need to hard code the credentials.

service.Proxy = WebRequest.DefaultWebProxy;
service.Credentials = System.Net.CredentialCache.DefaultCredentials; ;
service.Proxy.Credentials = System.Net.CredentialCache.DefaultCredentials;

• hstore is more of a "wide column" storage type, it is a flat (non-nested) dictionary of key-value pairs, always stored in a reasonably efficient binary format (a hash table, hence the name).
• json stores JSON documents as text, performing validation when the documents are stored, and parsing them on output if needed (i.e. accessing individual fields); it should support the entire JSON spec. Since the entire JSON text is stored, its formatting is preserved.
• jsonb takes shortcuts for performance reasons: JSON data is parsed on input and stored in binary format, key orderings in dictionaries are not maintained, and neither are duplicate keys. Accessing individual elements in the JSONB field is fast as it doesn't require parsing the JSON text all the time. On output, JSON data is reconstructed and initial formatting is lost.

IMO, there is no significant reason for not using jsonb once it is available, if you are working with machine-readable data.

Swift short expression:

var abc = "string"
abc != nil ? doWork(abc) : ()

or:

abc == nil ? () : abc = "string"

or both:

abc != nil ? doWork(abc) : abc = "string"

You are first setting opacity: 1; and then you are ending it on 0, so it starts from 0% and ends on 100%, so instead just set opacity to 0 at 50% and the rest will take care of itself.

Demo

.blink_me {_x000D_
  animation: blinker 1s linear infinite;_x000D_
}_x000D_
_x000D_
@keyframes blinker {_x000D_
  50% {_x000D_
    opacity: 0;_x000D_
  }_x000D_
}

<div class="blink_me">BLINK ME</div>

Here, I am setting the animation duration to be 1 second, and then I am setting the timing to linear. That means it will be constant throughout. Last, I am using infinite. That means it will go on and on.

Note: If this doesn't work for you, use browser prefixes like -webkit, -moz and so on as required for animation and @keyframes. You can refer to my detailed code here

As commented, this won't work on older versions of Internet Explorer, and for that you need to use jQuery or JavaScript...

(function blink() {
  $('.blink_me').fadeOut(500).fadeIn(500, blink);
})();

^{Thanks to Alnitak for suggesting a better approach.}

Demo (Blinker using jQuery)

For Visual Studio 2015 the connection string is:

"Data Source=(localdb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|Database1.mdf;Integrated Security=True"

1.Check your server status.

2.Check the port status.

For example 3306 netstat -nupl|grep 3306.

3.Check your firewalls. For example add 3306

vim /etc/sysconfig/iptables
# add
-A INPUT -p tcp -m state --state NEW -m tcp --dport 3306 -j ACCEPT

The selected answer would work for as long as you know the key itself that you want to delete but if it should be truly dynamic you would need to use the [] notation instead of the dot notation.

For example:

var keyToDelete = "key1";
var myObj = {"test": {"key1": "value", "key2": "value"}}

//that will not work.
delete myObj.test.keyToDelete 

instead you would need to use:

delete myObj.test[keyToDelete];

Substitute the dot notation with [] notation for those values that you want evaluated before being deleted.

Besides CMAKE_GENERATOR_PLATFORM variable, there is also the -A switch

cmake -G "Visual Studio 16 2019" -A Win32
cmake -G "Visual Studio 16 2019" -A x64

https://cmake.org/cmake/help/v3.16/generator/Visual%20Studio%2016%202019.html#platform-selection

  -A <platform-name>           = Specify platform name if supported by
                                 generator.

I also faced the same problem. Make sure you have same versions of JSTL in Eclipse and in the Tomcat work directory, i.e in \webapps\examples\WEB-INF\lib and in lib folder.

in addition to @lonkly solution

1. see reflections and field accessibility
2. unnecessary variables

method:

/**
 * lookup a resource id by field name in static R.class 
 * 
 * @author - ceph3us
 * @param variableName - name of drawable, e.g R.drawable.<b>image</b>
 * @param ?            - class of resource, e.g R.drawable.class or R.raw.class
 * @return integer id of resource
 */
public static int getResId(String variableName, Class<?> ?)
                     throws android.content.res.Resources.NotFoundException {
    try {
        // lookup field in class 
        java.lang.reflect.Field field = ?.getField(variableName);
        // always set access when using reflections  
        // preventing IllegalAccessException   
        field.setAccessible(true);
        // we can use here also Field.get() and do a cast 
        // receiver reference is null as it's static field 
        return field.getInt(null);
    } catch (Exception e) {
        // rethrow as not found ex
        throw new Resources.NotFoundException(e.getMessage());
    }
}

Also if you are looking for current file name along with the query string, you will just need following

basename($_SERVER['REQUEST_URI'])

It would provide you info like following example

file.php?arg1=val&arg2=val

And if you also want full path of file as well starting from root, e.g. /folder/folder2/file.php?arg1=val&arg2=val then just remove basename() function and just use fillowing

$_SERVER['REQUEST_URI']

Add pointer-events: none; to the overlay.

Original answer: My suggestion would be that you could capture the click event with the overlay, hide the overlay, then refire the click event, then display the overlay again. I'm not sure if you'd get a flicker effect though.

[Update] Exactly this problem and exactly my solution just appeared in this post: "Forwarding Mouse Events Through Layers". I know its probably a little late for the OP, but for the sake of somebody having this problem in the future, I though I would include it.

I liked @Brad's answer from this thread, but wanted a way to save the results for further processing (MySql 8):

-- May need to adjust the recursion depth first
SET @@cte_max_recursion_depth = 10000 ; -- permit deeper recursion

-- Some boundaries 
set @startDate = '2015-01-01'
    , @endDate = '2020-12-31' ; 

-- Save it to a table for later use
drop table if exists tmpDates ;
create temporary table tmpDates as      -- this has to go _before_ the "with", Duh-oh! 
    WITH RECURSIVE t as (
        select @startDate as dt
      UNION
        SELECT DATE_ADD(t.dt, INTERVAL 1 DAY) FROM t WHERE DATE_ADD(t.dt, INTERVAL 1 DAY) <= @endDate
    )
    select * FROM t     -- need this to get the "with"'s results as a "result set", into the "create"
;

-- Exists?
select * from tmpDates ;

Which produces:

dt        |
----------|
2015-01-01|
2015-01-02|
2015-01-03|
2015-01-04|

2015-01-06|

That's not how to add an item to a string. This:

newinv=inventory+str(add)

Means you're trying to concatenate a list and a string. To add an item to a list, use the list.append() method.

inventory.append(add) #adds a new item to inventory
print(inventory) #prints the new inventory

Hope this helps!

Just add catch all route at the end of the routes table and display whatever page you want with it.

See: How can i make a catch all route to handle '404 page not found' queries for ASP.NET MVC?

Here is a small JS_Fiddle.

then is a method callback stack which is available after a promise is resolved it is part of library like jQuery but now it is available in native JavaScript and below is the detail explanation how it works

You can do a Promise in native JavaScript : just like there are promises in jQuery, Every promise can be stacked and then can be called with Resolve and Reject callbacks, This is how you can chain asynchronous calls.

I forked and Edited from MSDN Docs on Battery charging status..

What this does is try to find out if user laptop or device is charging battery. then is called and you can do your work post success.

navigator
    .getBattery()
    .then(function(battery) {
       var charging = battery.charging;
       alert(charging);
    })
    .then(function(){alert("YeoMan : SINGH is King !!");});

Another es6 Example

function fetchAsync (url, timeout, onData, onError) {
    …
}
let fetchPromised = (url, timeout) => {
    return new Promise((resolve, reject) => {
        fetchAsync(url, timeout, resolve, reject)
    })
}
Promise.all([
    fetchPromised("http://backend/foo.txt", 500),
    fetchPromised("http://backend/bar.txt", 500),
    fetchPromised("http://backend/baz.txt", 500)
]).then((data) => {
    let [ foo, bar, baz ] = data
    console.log(`success: foo=${foo} bar=${bar} baz=${baz}`)
}, (err) => {
    console.log(`error: ${err}`)
})

Definition :: then is a method used to solve Asynchronous callbacks

this is introduced in ES6

Please find the proper documentation here Es6 Promises

try this:

<?php echo Mage::app()->getLocale()->currency(Mage::app()->getStore()->getCurrentCurrencyCode())->getSymbol(); ?>

Assume that you have

const appRoutes: Routes = [
  {path: 'recipes', component: RecipesComponent }
];

<a routerLink ="recipes">Recipes</a>

It means that clicking Recipes hyperlink will jump to http://localhost:4200/recipes

Assume that the parameter is 1

<a [routerLink] = "['/recipes', parameter]"></a>

It means that passing dynamic parameter, 1 to the link, then you navigate to http://localhost:4200/recipes/1

Following code works great. You need to reach your form elements' input changes via id attribute:

var somethingChanged=false;
            $('#managerForm input').change(function() { 
                somethingChanged = true; 
           }); 
            $(window).bind('beforeunload', function(e){
                if(somethingChanged)
                    return "You made some changes and it's not saved?";
                else 
                    e=null; // i.e; if form state change show warning box, else don't show it.
            });
        });

If you want to call the main method of another class you can do it this way assuming I understand the question.

public class MyClass {

    public static void main(String[] args) {

        System.out.println("main() method of MyClass");
        OtherClass obj = new OtherClass();
    }
}

class OtherClass {

    public OtherClass() {

        // Call the main() method of MyClass
        String[] arguments = new String[] {"123"};
        MyClass.main(arguments);
    }
}

You can export your methods to access from other files like this:

file1.js

var name = "Jhon";
exports.getName = function() {
  return name;
}

file2.js

var instance = require('./file1.js');
var name = instance.getName();

You can use the following in the web module that produces the war:

<build>
  <finalName>bird</finalName>
 . . .
</build>

This leads to a file called bird.war to be created when goal "war:war" is used.

as a general way of working with Fragments, as JafarKhQ noted, you should not pass the params in the constructor but with a Bundle.

the built-in method for that in the Fragment class is setArguments(Bundle) and getArguments().

basically, what you do is set up a bundle with all your Parcelable items and send them on.
in turn, your Fragment will get those items in it's onCreate and do it's magic to them.

the way shown in the DialogFragment link was one way of doing this in a multi appearing fragment with one specific type of data and works fine most of the time, but you can also do this manually.

It's a good approach.

If you just want to get a connection add the following code to your module where the pool is in:

var getConnection = function(callback) {
    pool.getConnection(function(err, connection) {
        callback(err, connection);
    });
};

module.exports = getConnection;

You still have to write getConnection every time. But you could save the connection in the module the first time you get it.

Don't forget to end the connection when you are done using it:

connection.release();

When using row and column groups both, I had an issue where the colors would alternate between the columns even though it was the same row. I resolved this by using a global variable that alternates only when the row changes:

Public Dim BGColor As String = "#ffffff"

Function AlternateColor() As String
  If BGColor = "#cccccc" Then
    BGColor = "#ffffff"
    Return "#cccccc"
  Else
    BGColor = "#cccccc"
    Return "#ffffff"
  End  If
End Function

Now, in the first column of the row you want to alternate, set the color expression to:

=Code.AlternateColor()

-

In the remaining columns, set them all to:

=Code.BGColor

This should make the colors alternate only after the first column is drawn.

This may (unverifiably) improve performance, too, since it does not need to do a math computation for each column.

Debugger for mysql was good but its not free. This is what i use now:

DELIMITER GO$

DROP PROCEDURE IF EXISTS resetLog

GO$

Create Procedure resetLog()

GO$

DROP PROCEDURE IF EXISTS doLog 

GO$

Try this in angular 8.0:

@ViewChild('result',{static: false}) resultElement: ElementRef;

For some - possibly valid - reason the url was encoded twice. %25 is the urlencoded % sign. So the original url looked like:

http://server.com/my path/

Then it got urlencoded once:

http://server.com/my%20path/

and twice:

http://server.com/my%2520path/

So you should do no urlencoding - in your case - as other components seems to to that already for you. Use simply a space

You need use just simple code <img alt="img" src="../assets/index.png" />

Do not forgot atribut alt in balise img

The following works fine on my mac

sed -i.bak 's/foo/bar/g' sample

We are replacing foo with bar in sample file. Backup of original file will be saved in sample.bak

For editing inline without backup, use the following command

sed -i'' 's/foo/bar/g' sample

Found the answer. In the file xampp\apache\conf\extra\httpd-ssl.conf, under the comment SSL Virtual Host Context pages on port 443 meaning https is looked up under different document root.

Simply change the document root to the same one and problem is fixed.

the behaviour of fixed elements (and absolute elements) as defined in CSS Spec:

They behave as they are detached from document, and placed in the nearest fixed/absolute positioned parent. (not a word by word quote)

This makes zindex calculation a bit complicated, I solved my problem (the same situation) by dynamically creating a container in body element and moving all such elements (which are class-ed as "my-fixed-ones" inside that body-level element)

This is a bad practice, often known as global namespace pollution. Problems may occur when more than one namespace has the same function name with signature, then it will be ambiguous for the compiler to decide which one to call and this all can be avoided when you are specifying the namespace with your function call like std::cout . Hope this helps. :)

With the directory parameter:

impdp system/password@$ORACLE_SID schemas=USER_SCHEMA directory=MY_DIR \
  dumpfile=mydumpfile.dmp logfile=impdpmydumpfile.log

The default directory is DATA_PUMP_DIR, which is presumably set to /u01/app/oracle/admin/mydatabase/dpdump on your system.

To use a different directory you (or your DBA) will have to create a new directory object in the database, which points to the Oracle-visible operating system directory you put the file into, and assign privileges to the user doing the import.

You have obviously gotten a lot of different recommendations.
My personal choice for a Free, 3rd Party Utility is: Agent Ransack
Agent Ransack Download
Despite its somewhat confusing name, it works well and can be used in a variety of ways to find files.

Good Luck

All of these answers should suffice. However if you don't have a defined width, auto margins will not work.

I have found this nifty little trick to centre some of the more stubborn elements (Particularly images).

.div {
   position: absolute;
   left: 0;
   right: 0;
   margin-left: 0;
   margin-right: 0;
}

Use CSS nth-child with the prefix class name

div.myclass:nth-child(1) {
  color: #000;
}

div.myclass:nth-child(2) {
  color: #FFF;
}

div.myclass:nth-child(3) {
  color: #006;
}

For Mac OS X, I really like LaunchRocket for this and other background services I used in development.

This site has nice instructions on installation.

This gives you a nice screen in your System Preferences that allows you to launch, reboot, root, and launch at login.

Keeping the solution simple and pythonic, I would suggest you to try this.

In case if you are going to do this frequently the best solution would be to first set the date column as index which will convert the column in DateTimeIndex and use the following condition to slice any range of dates.

import pandas as pd

data_frame = data_frame.set_index('date')

df = data_frame[(data_frame.index > '2017-08-10') & (data_frame.index <= '2017-08-15')]

Using jQuery:

$(document).ready(function(){
    $('div').click(function(){
        $(this).toggleClass('clicked');
    });
});?

Live example

Clustered Index

Clustered indexes sort and store the data rows in the table or view based on their key values. These are the columns included in the index definition. There can be only one clustered index per table, because the data rows themselves can be sorted in only one order.

The only time the data rows in a table are stored in sorted order is when the table contains a clustered index. When a table has a clustered index, the table is called a clustered table. If a table has no clustered index, its data rows are stored in an unordered structure called a heap.

Nonclustered

Nonclustered indexes have a structure separate from the data rows. A nonclustered index contains the nonclustered index key values and each key value entry has a pointer to the data row that contains the key value. The pointer from an index row in a nonclustered index to a data row is called a row locator. The structure of the row locator depends on whether the data pages are stored in a heap or a clustered table. For a heap, a row locator is a pointer to the row. For a clustered table, the row locator is the clustered index key.

You can add nonkey columns to the leaf level of the nonclustered index to by-pass existing index key limits, and execute fully covered, indexed, queries. For more information, see Create Indexes with Included Columns. For details about index key limits see Maximum Capacity Specifications for SQL Server.

If your text contains only one individual:

import re

# creation
with open('pers.txt','wb') as g:
    g.write('Dan \n Warrior \n 500 \r\n 1 \r 0 ')

with open('pers.txt','rb') as h:
    print 'exact content of pers.txt before treatment:\n',repr(h.read())
with open('pers.txt','rU') as h:
    print '\nrU-display of pers.txt before treatment:\n',h.read()


# treatment
def roplo(file_name,what):
    patR = re.compile('^([^\r\n]+[\r\n]+)[^\r\n]+')
    with open(file_name,'rb+') as f:
        ch = f.read()
        f.seek(0)
        f.write(patR.sub('\\1'+what,ch))
roplo('pers.txt','Mage')


# after treatment
with open('pers.txt','rb') as h:
    print '\nexact content of pers.txt after treatment:\n',repr(h.read())
with open('pers.txt','rU') as h:
    print '\nrU-display of pers.txt after treatment:\n',h.read()

If your text contains several individuals:

import re

# creation
with open('pers.txt','wb') as g:
    g.write('Dan \n Warrior \n 500 \r\n 1 \r 0 \n Jim  \n  dragonfly\r300\r2\n10\r\nSomo\ncosmonaut\n490\r\n3\r65')

with open('pers.txt','rb') as h:
    print 'exact content of pers.txt before treatment:\n',repr(h.read())
with open('pers.txt','rU') as h:
    print '\nrU-display of pers.txt before treatment:\n',h.read()


# treatment
def ripli(file_name,who,what):
    with open(file_name,'rb+') as f:
        ch = f.read()
        x,y = re.search('^\s*'+who+'\s*[\r\n]+([^\r\n]+)',ch,re.MULTILINE).span(1)
        f.seek(x)
        f.write(what+ch[y:])
ripli('pers.txt','Jim','Wizard')


# after treatment
with open('pers.txt','rb') as h:
    print 'exact content of pers.txt after treatment:\n',repr(h.read())
with open('pers.txt','rU') as h:
    print '\nrU-display of pers.txt after treatment:\n',h.read()

If the “job“ of an individual was of a constant length in the texte, you could change only the portion of texte corresponding to the “job“ the desired individual: that’s the same idea as senderle’s one.

But according to me, better would be to put the characteristics of individuals in a dictionnary recorded in file with cPickle:

from cPickle import dump, load

with open('cards','wb') as f:
    dump({'Dan':['Warrior',500,1,0],'Jim':['dragonfly',300,2,10],'Somo':['cosmonaut',490,3,65]},f)

with open('cards','rb') as g:
    id_cards = load(g)
print 'id_cards before change==',id_cards

id_cards['Jim'][0] = 'Wizard'

with open('cards','w') as h:
    dump(id_cards,h)

with open('cards') as e:
    id_cards = load(e)
print '\nid_cards after change==',id_cards

If you have a xml like below

<e:Envelope
    xmlns:d = "http://www.w3.org/2001/XMLSchema"
    xmlns:e = "http://schemas.xmlsoap.org/soap/envelope/"
    xmlns:wn0 = "http://systinet.com/xsd/SchemaTypes/"
    xmlns:i = "http://www.w3.org/2001/XMLSchema-instance">

                <Age>12121</Age>
                <Phone>Testpqr</Phone>

            <response i:type = "d:string">12--abc--pqr</response>
        </n0:ForAnsiHeaderOperResponse>
    </e:Body>
</e:Envelope>

and wanted to extract the below xml

<e:Header>
   <Friends>
      <friend>
         <Name>Testabc</Name>
         <Age>12121</Age>
         <Phone>Testpqr</Phone>
      </friend>
   </Friends>
</e:Header>

The below code helps to achieve the same

public static void main(String[] args) {

    File fXmlFile = new File("C://Users//abhijitb//Desktop//Test.xml");
    DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
    Document document;
    Node result = null;
    try {
        document = dbf.newDocumentBuilder().parse(fXmlFile);
        XPath xPath = XPathFactory.newInstance().newXPath();
        String xpathStr = "//Envelope//Header";
        result = (Node) xPath.evaluate(xpathStr, document, XPathConstants.NODE);
        System.out.println(nodeToString(result));
    } catch (SAXException | IOException | ParserConfigurationException | XPathExpressionException
            | TransformerException e) {
        e.printStackTrace();
    }
}

private static String nodeToString(Node node) throws TransformerException {
    StringWriter buf = new StringWriter();
    Transformer xform = TransformerFactory.newInstance().newTransformer();
    xform.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
    xform.transform(new DOMSource(node), new StreamResult(buf));
    return (buf.toString());
}

Now if you want only the xml like below

<Friends>
   <friend>
      <Name>Testabc</Name>
      <Age>12121</Age>
      <Phone>Testpqr</Phone>
   </friend>
</Friends>

You need to change the

String xpathStr = "//Envelope//Header"; to String xpathStr = "//Envelope//Header/*";

For various reasons, Multimedia was and is never easy in terms of achieving the task without compromising on efficiency. ffmpeg is an effort in improving it day by day. It supports different formats of codecs and containers.

Now to answer the question of how to use this library, i would say that it is not so simple to write it here. But i can guide you in following ways.

1) Inside the ffmpeg directory of source code, you have output_example.c or api_example.c. Here, you can see the code where encoding/decoding is done. You will get an idea as to which API's inside ffmpeg you should call. This would be your first step.

2) Dolphin player is a open source project for Android. Currently it is having bugs but developers are working continuously. In that project you have the whole setup ready which you can use to continue your investigation. Here is a link to the project from code.google.com or run the command "git clone https://code.google.com/p/dolphin-player/" in a terminal. You can see two projects named P and P86 . You can use either of them.

Extra tip i would like to offer is that when you are building the ffmpeg code, inside build.sh you need to enable the muxers/demuxers/encoders/decoders of the formats you want to use. Else the corresponding code will not be included in the libraries. It took a lot of time for me to realize this. So thought of sharing it with you.

Few Basics : When we say a video file, ex : avi, it is combination of both audio and video

Video file = Video + Audio

Video = Codec + Muxer + Demuxer

codec = encoder + Decoder

=> Video = encoder + decoder + Muxer + Demuxer(Mpeg4 + Mpeg4 + avi +avi - Example for avi container)

Audio = Codec + Muxer + Demuxer

codec = encoder + Decoder

=> Audio = encoder + decoder + Muxer + Demuxer(mp2 + mp2 + avi + avi - Example for avi container)

Codec(name is deriverd from a combination of en*co*der/*dec*oder) is just a part of format which defines the algorithms used to encode/decode a frame. AVI is not a codec, it is a container which uses Video codec of Mpeg4 and Audio codec of mp2.

Muxer/demuxer is used to combine/separate the frames from a file used while encoding/decoding.

So if you want to use avi format, you need to enable Video components + Audio components.

Ex, for avi, you need to enable the following. mpeg4 Encoder, mpeg4 decoder, mp2 encoder, mp2 decoder, avi muxer, avi demuxer.

phewwwwwww...

Programmatically build.sh should contain the following code:

--enable-muxer=avi --enable-demuxer=avi (Generic for both audio/video. generally Specific to a container)
--enable-encoder=mpeg4 --enable-decoder=mpeg4(For video support)
--enable-encoder=mp2 --enable-decoder=mp2 (For Audio support)

Hope i idid not confuse you more after all this...

Thanks, Any assistance needed, please let me know.

There are a few different ways. If you want to do it yourself on the fly WMI is probably the way to go. RegistryKeyChangeEvent and its relatives are the ones to look at. There might be a way to monitor it through __InstanceCreationEvent, __InstanceDeletionEvent and __InstanceModificationEvent classes too.

If your shell is bash (amongst others), a shortcut for $(cat afile) is $(< afile), so you'd write:

mycommand "$(< file.txt)"

Documented in the bash man page in the 'Command Substitution' section.

Alterately, have your command read from stdin, so: mycommand < file.txt

@ComponentScan uses string array, like this:

@ComponentScan({"com.my.package.first","com.my.package.second"})

When you provide multiple package names in only one string, Spring interprets this as one package name, and thus can't find it.

This seems like an old thread, but I'll add my experience here. I tried to install a cert as well and got that error. I then opened the cer file with a txt editor, and noticed that there is an extra space (character) at the end of each line. Removing those lines allowed me to import the cert.

Hope this is worth something to someone else.

Try adding display: table-cell; width: 1%; to your table cell element.

.table-cell {_x000D_
  display: table-cell;_x000D_
  width: 1%;_x000D_
  padding: 4px;_x000D_
  border: 1px solid #efefef;_x000D_
}

<div class="table">_x000D_
  <div class="table-cell">one</div>_x000D_
  <div class="table-cell">two</div>_x000D_
  <div class="table-cell">three</div>_x000D_
  <div class="table-cell">four</div>_x000D_
</div>_x000D_
<div class="table">_x000D_
  <div class="table-cell">one</div>_x000D_
  <div class="table-cell">two</div>_x000D_
  <div class="table-cell">three</div>_x000D_

select CONVERT(NVARCHAR, SYSDATETIME(), 106) AS [DD-MON-YYYY]

or else

select REPLACE(CONVERT(NVARCHAR,GETDATE(), 106), ' ', '-')

both works fine

Dang this is hard. Here is what I did to reject/delete/replace my ios build before it was released. The app was approved how ever I found found a bug I wanted to fix before releasing

1. I set release to "manual" and saved
2. I tried to create and app release
3. got an error message something like "you can only have one release at a time"
4. where the save button was there was not an option to cancel release
5. the version of the app is not marked "developer rejected" with a red dot

To replace the bad build I did the following

1. if you click on the "+ version or platform" to create a new version you will not be be able to create a new iOS version
2. you need to upload a new build
3. in your rejected app, select the new build
4. save
5. submit for review

In comparisons it makes a difference if a scalar is a number of a string. And it is not always decidable. I can report a case where perl retrieved a float in "scientific" notation and used that same a few lines below in a comparison:

use strict;
....
next unless $line =~ /and your result is:\s*(.*)/;
my $val = $1;
if ($val < 0.001) {
   print "this is small\n";
}

And here $val was not interpreted as numeric for e.g. "2e-77" retrieved from $line. Adding 0 (or 0.0 for good ole C programmers) helped.

$(document).ready(function(){
   $('.somediv').click(function(){
   $(this).addClass('newDiv'); // this means the div which is clicked
   });                         // so instead of using a selector again $('.somediv');
});                           // you use $(this) which much better and neater:=)

This may be achieved by using AppCompatCheckBox. You can use app:buttonCompat="@drawable/selector_drawable" to change the selector.

It's working with PNGs, but I didn't find a way for it to work with Vector Drawables.

#The Best way is to use `fStrings` (very easy and powerful in python3)   
#Format: f'your-string'   
#For Example:

mylist=['laks',444,'M']

cursor.execute(f'INSERT INTO mytable VALUES ("{mylist[0]}","{mylist[1]}","{mylist[2]}")')

#THATS ALL!! EASY!!
#You can use it with for loop!

driver.findElement(By.id("urid")).sendKeys("drive:\\path\\filename.extension");

You can extends for any language with 1 keybinding with augroup command, for example:

augroup rungroup
    autocmd!
    autocmd BufRead,BufNewFile *.go nnoremap <F5> :exec '!go run' shellescape(@%, 1)<cr>
    autocmd BufRead,BufNewFile *.py nnoremap <F5> :exec '!python' shellescape(@%, 1)<cr>
augroup END

Try putting the search condition in a bracket, as shown below. This returns the result of the conditional query inside the bracket. Then test its result to determine if it is negative (i.e. it does not belong to any of the options in the vector), by setting it to FALSE.

SE_CSVLinelist_filtered <- filter(SE_CSVLinelist_clean, 
(where_case_travelled_1 %in% c('Outside Canada','Outside province/territory of residence but within Canada')) == FALSE)

Try this

• Find: ([A-Z])([A-Z]+)\b
• Replace: $1\L$2

Make sure case sensitivity is on (Alt + C)

if you get to use the q library https://github.com/kriskowal/q it has q.allSettled() method that can solve this problem you can handle every promise depending on its state either fullfiled or rejected so

existingPromiseChain = existingPromiseChain.then(function() {
var arrayOfPromises = state.routes.map(function(route){
  return route.handler.promiseHandler();
});
return q.allSettled(arrayOfPromises)
});

existingPromiseChain = existingPromiseChain.then(function(arrayResolved) {
//so here you have all your promises the fulfilled and the rejected ones
// you can check the state of each promise
arrayResolved.forEach(function(item){
   if(item.state === 'fulfilled'){ // 'rejected' for rejected promises
     //do somthing
   } else {
     // do something else
   }
})
// do stuff with my array of resolved promises, eventually ending with a res.send();
});

Pure speculation is that you're using a terminal that attempts to do word-wrapping rather than character-wrapping, and treats B as a word character but # as a non-word character. So when it reaches the end of a line and searches for a place to break the line, it sees a # almost immediately and happily breaks there; whereas with the B, it has to keep searching for longer, and may have more text to wrap (which may be expensive on some terminals, e.g., outputting backspaces, then outputting spaces to overwrite the letters being wrapped).

But that's pure speculation.

The host should be specified in each environment's config file. Eg:

config/environments/development.rb

See this question and this question.

createOrReplaceTempView creates (or replaces if that view name already exists) a lazily evaluated "view" that you can then use like a hive table in Spark SQL. It does not persist to memory unless you cache the dataset that underpins the view.

scala> val s = Seq(1,2,3).toDF("num")
s: org.apache.spark.sql.DataFrame = [num: int]

scala> s.createOrReplaceTempView("nums")

scala> spark.table("nums")
res22: org.apache.spark.sql.DataFrame = [num: int]

scala> spark.table("nums").cache
res23: org.apache.spark.sql.Dataset[org.apache.spark.sql.Row] = [num: int]

scala> spark.table("nums").count
res24: Long = 3

The data is cached fully only after the .count call. Here's proof it's been cached:

Related SO: spark createOrReplaceTempView vs createGlobalTempView

Relevant quote (comparing to persistent table): "Unlike the createOrReplaceTempView command, saveAsTable will materialize the contents of the DataFrame and create a pointer to the data in the Hive metastore." from https://spark.apache.org/docs/latest/sql-programming-guide.html#saving-to-persistent-tables

Note : createOrReplaceTempView was formerly registerTempTable

You have to style the image like this

#container img{width:100%;}

and the container with hidden overflow:

#container{width:250px; height:250px; overflow:hidden; border:1px solid #000;} 

Here's what I ended up using.

I'm very new to AngularJS, so would love to see better / alternative solutions.

angular.module('formComponents', [])
    .directive('formInput', function() {
        return {
            restrict: 'E',
            scope: {},
            link: function(scope, element, attrs)
            {
                var type = attrs.type || 'text';
                var required = attrs.hasOwnProperty('required') ? "required='required'" : "";
                var htmlText = '<div class="control-group">' +
                    '<label class="control-label" for="' + attrs.formId + '">' + attrs.label + '</label>' +
                        '<div class="controls">' +
                        '<input type="' + type + '" class="input-xlarge" id="' + attrs.formId + '" name="' + attrs.formId + '" ' + required + '>' +
                        '</div>' +
                    '</div>';
                element.html(htmlText);
            }
        }
    })

Example usage:

<form-input label="Application Name" form-id="appName" required/></form-input>
<form-input type="email" label="Email address" form-id="emailAddress" required/></form-input>
<form-input type="password" label="Password" form-id="password" /></form-input>

I am now able to successfully build. Not sure exactly which step "fixed" things, but this was the sequence:

• Tried automatic signing again. No go, so reverted to manual.
• After reverting, I had no Eligible Profiles, all were ineligible. Strange.
• I created a new certificate and profile, imported both. This too was "ineligible".
• Removed the iOS platform and re-added it. I had tried this previously without luck.
• After doing this, Xcode on its own defaulted to automatic signing. And this worked! Success!

While I am not sure exactly which parts were necessary, I think the previous certificates were the problem. I hate Xcode :(

Thanks for help.

<form id="uploadForm" class="disp-inline" role="form" action="" method="post" enctype="multipart/form-data">
    <input type="file" name="file" id="file">
</form>
<button onclick="checkSize();"></button>
<script>
    function checkSize(){
        var size = $('#uploadForm')["0"].firstChild.files["0"].size;
        console.log(size);
    }
</script>

I found this to be the easiest if you don't plan on submitted the form through standard ajax / html5 methods, but of course it works with anything.

NOTES:

var size = $('#uploadForm')["0"]["0"].files["0"].size;

This used to work, but it doesn't in chrome anymore, i just tested the code above and it worked in both ff and chrome (lastest). The second ["0"] is now firstChild.

I believe you are looking for -maxdepth 1.

@echo off
for /f "usebackq tokens=*" %%x in (`chdir`) do set var=%%x
echo The currenct directory is: %var%

But, of course, gmaran23's answer is the much easier one.

If you're using ZLib in your project, then you need to find :

#if 1

in zconf.h and replace(uncomment) it with :

#if HAVE_UNISTD_H /* ...the rest of the line

If it isn't ZLib I guess you should find some alternative way to do this. GL.

A similar question's answer worked more correctly for me than this question's selected answer (by Mark Byers). Using Mark's answer, my updated column got the same value in all the rows (perhaps the value from the first row that matched the join). Using ParveenaArora's answer from the other thread updated the column with the correct values.

Transforming Parveena's solution to use this question' table and column names, the query would be as follows (where I assume the tables are related through tblindiantime.contact_id):

UPDATE tblindiantime
SET CountryName = contacts.BusinessCountry
FROM contacts
WHERE tblindiantime.contact_id = contacts.id;

In Linux I navigated to the directory containing the .sql file before starting mysql. The system cursor is now in the same location as the file and you won't need a path. Use source myData.sql where my date is replaced with the name of your file.

cd whatever directory

mysql - p

connect targetDB

source myData.sql

Done

To address this problem, I have used setx command which try to set user level variables.

I used below...

setx JAVA_HOME "C:\Program Files\Java\jdk1.8.0_92"

setx PATH %JAVA_HOME%\bin

NOTE: Windows try to append provided variable value to existing variable value. So no need to give extra %PATH%... something like %JAVA_HOME%\bin;%PATH%

If you are using Sentry check the logged in user with Sentry::getUser()->id. The error you get is that the Auth::user() returns NULL and it tries to get id from NULL hence the error trying to get a property from a non-object.

Here is my POST method with HTTPS which returns a response body for any type of bad responses.

public String postHTTPSRequest(String url,String requestJson)
{
    //SSL Context
    CloseableHttpClient httpClient = HttpClients.custom().setSSLHostnameVerifier(new NoopHostnameVerifier()).build();
    HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
    requestFactory.setHttpClient(httpClient);
    //Initiate REST Template
    RestTemplate restTemplate = new RestTemplate(requestFactory);
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_JSON);
    //Send the Request and get the response.
    HttpEntity<String> entity = new HttpEntity<String>(requestJson,headers);
    ResponseEntity<String> response;
    String stringResponse = "";
    try {
        response = restTemplate.postForEntity(url, entity, String.class);
        stringResponse = response.getBody();
    }
    catch (HttpClientErrorException e)
    {
        stringResponse = e.getResponseBodyAsString();
    }
    return stringResponse;
}

Since my edit to Mike G's answer to modernize the code was rejected 3 to 2 as

This edit was intended to address the author of the post and makes no sense as an edit. It should have been written as a comment or an answer

I'm reposting my edit as a separate answer here. This edit removes the JSONRepresentation dependency with NSJSONSerialization as Rob's comment with 15 upvotes suggests.

    NSArray *objects = [NSArray arrayWithObjects:[[NSUserDefaults standardUserDefaults]valueForKey:@"StoreNickName"],
      [[UIDevice currentDevice] uniqueIdentifier], [dict objectForKey:@"user_question"],     nil];
    NSArray *keys = [NSArray arrayWithObjects:@"nick_name", @"UDID", @"user_question", nil];
    NSDictionary *questionDict = [NSDictionary dictionaryWithObjects:objects forKeys:keys];

    NSDictionary *jsonDict = [NSDictionary dictionaryWithObject:questionDict forKey:@"question"];

    NSLog(@"jsonRequest is %@", jsonRequest);

    NSURL *url = [NSURL URLWithString:@"https://xxxxxxx.com/questions"];

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
                 cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];


    NSData *requestData = [NSJSONSerialization dataWithJSONObject:dict options:0 error:nil]; //TODO handle error

    [request setHTTPMethod:@"POST"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [request setValue:[NSString stringWithFormat:@"%d", [requestData length]] forHTTPHeaderField:@"Content-Length"];
    [request setHTTPBody: requestData];

    NSURLConnection *connection = [[NSURLConnection alloc]initWithRequest:request delegate:self];
    if (connection) {
     receivedData = [[NSMutableData data] retain];
    }

The receivedData is then handled by:

NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
    NSDictionary *question = [jsonDict objectForKey:@"question"];

to get all tables in a database:

select * from INFORMATION_SCHEMA.TABLES

to get all columns in a database:

select * from INFORMATION_SCHEMA.columns

to get all views in a db:

select * from INFORMATION_SCHEMA.TABLES where table_type = 'view'

Update:

There is now a to_sql method, which is the preferred way to do this, rather than write_frame:

df.to_sql(con=con, name='table_name_for_df', if_exists='replace', flavor='mysql')

Also note: the syntax may change in pandas 0.14...

You can set up the connection with MySQLdb:

from pandas.io import sql
import MySQLdb

con = MySQLdb.connect()  # may need to add some other options to connect

Setting the flavor of write_frame to 'mysql' means you can write to mysql:

sql.write_frame(df, con=con, name='table_name_for_df', 
                if_exists='replace', flavor='mysql')

The argument if_exists tells pandas how to deal if the table already exists:

if_exists: {'fail', 'replace', 'append'}, default 'fail'
     fail: If table exists, do nothing.
     replace: If table exists, drop it, recreate it, and insert data.
     append: If table exists, insert data. Create if does not exist.

Although the write_frame docs currently suggest it only works on sqlite, mysql appears to be supported and in fact there is quite a bit of mysql testing in the codebase.

As @Brian Riley already said you should either remove 1 column in your select

select countrylanguage.language ,sum(country.population*countrylanguage.percentage/100)
from countrylanguage
join country on countrylanguage.countrycode = country.code
group by countrylanguage.language
order by sum(country.population*countrylanguage.percentage) desc ;

or add it to your grouping

select countrylanguage.language, country.code, sum(country.population*countrylanguage.percentage/100)
from countrylanguage
join country on countrylanguage.countrycode = country.code
group by countrylanguage.language, country.code
order by sum(country.population*countrylanguage.percentage) desc ;

You can use this approach, it works even if a lot of files inputs.

const fileBlocks = document.querySelectorAll('.file-block')_x000D_
const buttons = document.querySelectorAll('.btn-select-file')_x000D_
_x000D_

Java lacks coalesce operator, so your code with an explicit temporary is your best choice for an assignment with a single call.

You can use the result variable as your temporary, like this:

dinner = ((dinner = cage.getChicken()) != null) ? dinner : getFreeRangeChicken();

This, however, is hard to read.

works

scp localhost:"f/a\ b\ c" .

scp localhost:'f/a\ b\ c' .

does not work

scp localhost:'f/a b c' .

The reason is that the string is interpreted by the shell before the path is passed to the scp command. So when it gets to the remote the remote is looking for a string with unescaped quotes and it fails

To see this in action, start a shell with the -vx options ie bash -vx and it will display the interpolated version of the command as it runs it.

I've written a library that is up-to-date, since all the other answers are outdated:

https://github.com/flagbug/YoutubeExtractor

I think, bwawok's answer is wrong at some point:

if you do

git reset --soft c14809fa

It will make your local files changed to be like they were then, but leave your history etc. the same.

According to manual: git-reset, "git reset --soft"...

does not touch the index file nor the working tree at all (but resets the head to <commit>, just like all modes do). This leaves all your changed files "Changes to be committed", as git status would put it.

So it will "remove" newer commits from the branch. This means, after looking at your old code, you cannot go to the newest commit in this branch again, easily. So it does the opposide as described by bwawok: Local files are not changed (they look exactly as before "git reset --soft"), but the history is modified (branch is truncated after the specified commit).

The command for bwawok's answer might be:

git checkout <commit>

You can use this to peek at old revision: How did my code look yesterday?

(I know, I should put this in comments to this answer, but stackoverflow does not allow me to do so! My reputation is too low.)

I always liked going after it directly:

SELECT 
    DB_NAME( dbid ) AS DatabaseName, 
    CAST( ( SUM( size ) * 8 ) / ( 1024.0 * 1024.0 ) AS decimal( 10, 2 ) ) AS DbSizeGb 
FROM 
    sys.sysaltfiles 
GROUP BY 
    DB_NAME( dbid )

On the client side you can add and remove websites to be displayed in Compatibility View from Compatibility View Settings window of IE:

Tools-> Compatibility View Settings

For example to execute from terminal (Ubuntu Linux) or even (Windows console) a java file called filex.jar use this command:

java -jar filex.jar

The file will execute in terminal.

Support for TLS 1.0 and 1.1 was dropped for PyPI. If your system does not use a more recent version, it could explain your error.

Could you try reinstalling pip system-wide, to update your system dependencies to a newer version of TLS?

This seems to be related to Unable to install Python libraries

See Dominique Barton's answer:

Apparently pip is trying to access PyPI via HTTPS (which is encrypted and fine), but with an old (insecure) SSL version. Your system seems to be out of date. It might help if you update your packages.

On Debian-based systems I'd try:

apt-get update && apt-get upgrade python-pip

On Red Hat Linux-based systems:

yum update python-pip # (or python2-pip, at least on Red Hat Linux 7)

On Mac:

sudo easy_install -U pip

You can also try to update openssl separately.

If you are on t2 instances (t2.micro, t2.medium, t2.small), there is no ephemeral or instance storage available to you. So you need to just create your swap in EBS which depending on your use case may or maynot be a good idea. Otherwise follow @David 's answer, and create your swap on the ephemeral storage to avoid paying EBS costs.

More info: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/InstanceStorage.html there is a table that shows how much ephemeral storage you get for each instance type.

In .NET 3.0 and later you can use the ISOWeek.GetWeekOfDate-Method.

Note that the year in the year + week number format might differ from the year of the DateTime because of weeks that cross the year boundary.
