This was considered a bug in 2013: https://jira.spring.io/browse/SPR-10180

and was fixed with version 3.2.2. Problem shouldn't occur in any versions after that and your code should work just fine.

Use something like the following, taking advantage of the XML output of subversion:

# parse rev from popen "svn info --xml"
dom = xml.dom.minidom.parse(os.popen('svn info --xml'))
entry = dom.getElementsByTagName('entry')[0]
revision = entry.getAttribute('revision')

Note also that, depending on what you need this for, the <commit revision=...> entry may be more what you're looking for. That gives the "Last Changed Rev", which won't change until the code in the current tree actually changes, as opposed to "Revision" (what the above gives) which will change any time anything in the repository changes (even branches) and you do an "svn up", which is not the same thing, nor often as useful.

public void clearData() {
    mylist.removeAll(mylist);
    mAdapter.notifyDataSetChanged();
    recyclerView.setAdapter(mAdapter);
}

You can also open the file in r+ mode and then set the file position to the end of the file.

import os

with open('text.txt', 'r+') as f:
    f.seek(0, os.SEEK_END)
    f.write("text to add")

Opening the file in r+ mode will let you write to other file positions besides the end, while a and a+ force writing to the end.

I am using Angular v11 and was facing this error while trying to lazy load a component (await import('./my-component.component')) and even if import and export were correctly set.

I finally figured out that the solution was deleting the separate dedicated module's file and move the module content inside the component file itself.

rm -r my-component.module.ts

and add module inside my-component.ts (same file)

@Component({
  selector: 'app-my-component',
  templateUrl: './my-component.page.html',
  styleUrls: ['./my-component.page.scss'],
})
export class MyComponent {
}

@NgModule({
  imports: [CommonModule],
  declarations: [MyComponent],
})
export class MyComponentModule {}

if(strcmp(aString, bString) == 0){
    //strings are the same
}

godspeed

(For Python2.7* only; there are simpler solutions for Python3*.)

If you're not averse to importing a standard library module, you can do

from functools import reduce

def merge_dicts(*dicts):
    return reduce(lambda a, d: a.update(d) or a, dicts, {})

(The or a bit in the lambda is necessary because dict.update always returns None on success.)

Using Scipy's zscore function:

df = pd.DataFrame(np.random.randint(100, 200, size=(5, 3)), columns=['A', 'B', 'C'])
df

|    |   A |   B |   C |
|---:|----:|----:|----:|
|  0 | 163 | 163 | 159 |
|  1 | 120 | 153 | 181 |
|  2 | 130 | 199 | 108 |
|  3 | 108 | 188 | 157 |
|  4 | 109 | 171 | 119 |

from scipy.stats import zscore
df.apply(zscore)

|    |         A |         B |         C |
|---:|----------:|----------:|----------:|
|  0 |  1.83447  | -0.708023 |  0.523362 |
|  1 | -0.297482 | -1.30804  |  1.3342   |
|  2 |  0.198321 |  1.45205  | -1.35632  |
|  3 | -0.892446 |  0.792025 |  0.449649 |
|  4 | -0.842866 | -0.228007 | -0.950897 |

If not all the columns of your data frame are numeric, then you can apply the Z-score function only to the numeric columns using the select_dtypes function:

# Note that `select_dtypes` returns a data frame. We are selecting only the columns
numeric_cols = df.select_dtypes(include=[np.number]).columns
df[numeric_cols].apply(zscore)

|    |         A |         B |         C |
|---:|----------:|----------:|----------:|
|  0 |  1.83447  | -0.708023 |  0.523362 |
|  1 | -0.297482 | -1.30804  |  1.3342   |
|  2 |  0.198321 |  1.45205  | -1.35632  |
|  3 | -0.892446 |  0.792025 |  0.449649 |
|  4 | -0.842866 | -0.228007 | -0.950897 |

function cool(d)_x000D_
{_x000D_
    alert(d.value.length);_x000D_
}

<input type="text" value="" onblur="cool(this)">

It will return the length of string

Instead of blur use keydown event.

Based on an answer by Clay Bridges, here is an example of filtering using blocks (change yourArray to your array variable name and testFunc to the name of your testing function):

yourArray = [yourArray objectsAtIndexes:[yourArray indexesOfObjectsPassingTest:^BOOL(id obj, NSUInteger idx, BOOL *stop) {
    return [self testFunc:obj];
}]];

Yet another method - create a filter function that returns True for all desired tags:

def my_filter(tag):
    return (tag.name == 'a' and
        tag.parent.name == 'li' and
        'test' in tag.parent['class'])

Then just call find_all with the argument:

for a in soup(my_filter): # or soup.find_all(my_filter)
    print a

Maybe a little late, but I found an easier way to set the defaults! You have to right-click on the right of your tab and choose "size", then click on your window, and it should keep it as the default size.

int i = (int) (10 +Math.random()*11);

this will give you random number between 10 to 20.

the key here is:

a + Math.random()*b

a starting num (10) and ending num is max number (20) - a (10) + 1 (11)

Enjoy!

Try using an anonymous function instead:

expect( function(){ parser.parse(raw); } ).toThrow(new Error("Parsing is not possible"));

you should be passing a function into the expect(...) call. Your incorrect code:

// incorrect:
expect(parser.parse(raw)).toThrow(new Error("Parsing is not possible"));

is trying to actually call parser.parse(raw) in an attempt to pass the result into expect(...),

You can do it right in your XML file:

android:onClick="@drawable/ic_action_search"

Gradle cache is located at

• On Windows: %USERPROFILE%\.gradle\caches
• On Mac / UNIX: ~/.gradle/caches/

You can browse to these directory and manually delete it or run

rm -rf $HOME/.gradle/caches/

on UNIX system. Run this command will also force to download dependencies.

UPDATE

Clear the Android build cache of current project

NOTE: Android Studio's File > Invalidate Caches / Restart doesn't clear the Android build cache, so you'll have to clean it separately.

On Windows:

gradlew cleanBuildCache

On Mac or UNIX:

./gradlew cleanBuildCache

Suppose your existing reporting query is

Select EmployeeId,EmployeeName

Where EmployeeId>101 order by EmployeeName

and you have to save this data into temparory table then you query goes to

Select EmployeeId,EmployeeName

from Employee 
Where EmployeeId>101 order by EmployeeName  

Yes, we can do this way.

If you are serializing your data object, it will not be a proper json object. Take what you have, and just wrap the data object in a JSON.stringify().

$http({
    url: '/user_to_itsr',
    method: "POST",
    data: JSON.stringify({application:app, from:d1, to:d2}),
    headers: {'Content-Type': 'application/json'}
}).success(function (data, status, headers, config) {
    $scope.users = data.users; // assign  $scope.persons here as promise is resolved here 
}).error(function (data, status, headers, config) {
    $scope.status = status + ' ' + headers;
});

With python 3.6, these two lines return a list (may be empty)

>>[int(x) for x in re.findall('\d+', your_string)]

Similar to

>>list(map(int, re.findall('\d+', your_string))

You can get the total number of rows containing a specific name using:

SELECT COUNT(*) FROM tbl_foo WHERE name = 'sarmen'

Given the count, you can now get the nth row using:

SELECT * FROM tbl_foo WHERE name = 'sarmen' LIMIT (n - 1), 1

Where 1 <= n <= COUNT(*) from the first query.

Example:

getting the 3rd row

SELECT * FROM tbl_foo WHERE name = 'sarmen' LIMIT 2, 1

df = pd.concat([df['a'], df.b.apply(pd.Series)], axis=1)

I used bluga. The api allows you to take 100 snapshots a month without paying, but sometimes it uses more than 1 credit for a single page. I just finished upgrading a drupal module, Bluga WebThumbs to drupal 7 which allows you to print a thumbnail in a template or input filter.

The main advantage to using this api is that it allows you to specify browser dimensions in case you use adaptive css, so I am using it to get renderings for the mobile and tablet layout as well as the regular one.

There are api clients for the following languages:

PHP, Python, Ruby, Java, .Net C#, Perl and Bash (the shell script looks like it requires perl)

Make sure the folder you have created inside htdocs are present there and you browse the right url.

for example

• 301: permanent redirect: the URL is old and should be replaced. Browsers will cache this.
  Example usage: URL moved from /register-form.html to signup-form.html.
  The method will change to GET, as per RFC 7231: "For historical reasons, a user agent MAY change the request method from POST to GET for the subsequent request."
• 302: temporary redirect. Only use for HTTP/1.0 clients. This status code should not change the method, but browsers did it anyway. The RFC says: "Many pre-HTTP/1.1 user agents do not understand [303]. When interoperability with such clients is a concern, the 302 status code may be used instead, since most user agents react to a 302 response as described here for 303." Of course, some clients may implement it according to the spec, so if interoperability with such ancient clients is not a real concern, 303 is better for consistent results.
• 303: temporary redirect, changing the method to GET.
  Example usage: if the browser sent POST to /register.php, then now load (GET) /success.html.
• 307: temporary redirect, repeating the request identically.
  Example usage: if the browser sent a POST to /register.php, then this tells it to redo the POST at /signup.php.
• 308: permanent redirect, repeating the request identically. Where 307 is the "no method change" counterpart of 303, this 308 status is the "no method change" counterpart of 301.

RFC 7231 (from 2014) is very readable and not overly verbose. If you want to know the exact answer, it's a recommended read. Some other answers use RFC 2616 from 1999, but nothing changed.

RFC 7238 specifies the 308 status. It is considered experimental, but it was already supported by all major browsers in 2016.

I'm going to order this guide by the level of skill you have in Haskell, going from an absolute beginner right up to an expert. Note that this process will take many months (years?), so it is rather long.

Absolute Beginner

Firstly, Haskell is capable of anything, with enough skill. It is very fast (behind only C and C++ in my experience), and can be used for anything from simulations to servers, guis and web applications.

However there are some problems that are easier to write for a beginner in Haskell than others. Mathematical problems and list process programs are good candidates for this, as they only require the most basic of Haskell knowledge to be able to write.

Some good guides to learning the very basics of Haskell are the Happy Learn Haskell Tutorial and the first 6 chapters of Learn You a Haskell for Great Good (or its JupyterLab adaptation). While reading these, it is a very good idea to also be solving simple problems with what you know.

Another two good resources are Haskell Programming from first principles, and Programming in Haskell. They both come with exercises for each chapter, so you have small simple problems matching what you learned on the last few pages.

A good list of problems to try is the haskell 99 problems page. These start off very basic, and get more difficult as you go on. It is very good practice doing a lot of those, as they let you practice your skills in recursion and higher order functions. I would recommend skipping any problems that require randomness as that is a bit more difficult in Haskell. Check this SO question in case you want to test your solutions with QuickCheck (see Intermediate below).

Once you have done a few of those, you could move on to doing a few of the Project Euler problems. These are sorted by how many people have completed them, which is a fairly good indication of difficulty. These test your logic and Haskell more than the previous problems, but you should still be able to do the first few. A big advantage Haskell has with these problems is Integers aren't limited in size. To complete some of these problems, it will be useful to have read chapters 7 and 8 of learn you a Haskell as well.

Beginner

After that you should have a fairly good handle on recursion and higher order functions, so it would be a good time to start doing some more real world problems. A very good place to start is Real World Haskell (online book, you can also purchase a hard copy). I found the first few chapters introduced too much too quickly for someone who has never done functional programming/used recursion before. However with the practice you would have had from doing the previous problems you should find it perfectly understandable.

Working through the problems in the book is a great way of learning how to manage abstractions and building reusable components in Haskell. This is vital for people used to object-orientated (oo) programming, as the normal oo abstraction methods (oo classes) don't appear in Haskell (Haskell has type classes, but they are very different to oo classes, more like oo interfaces). I don't think it is a good idea to skip chapters, as each introduces a lot new ideas that are used in later chapters.

After a while you will get to chapter 14, the dreaded monads chapter (dum dum dummmm). Almost everyone who learns Haskell has trouble understanding monads, due to how abstract the concept is. I can't think of any concept in another language that is as abstract as monads are in functional programming. Monads allows many ideas (such as IO operations, computations that might fail, parsing,...) to be unified under one idea. So don't feel discouraged if after reading the monads chapter you don't really understand them. I found it useful to read many different explanations of monads; each one gives a new perspective on the problem. Here is a very good list of monad tutorials. I highly recommend the All About Monads, but the others are also good.

Also, it takes a while for the concepts to truly sink in. This comes through use, but also through time. I find that sometimes sleeping on a problem helps more than anything else! Eventually, the idea will click, and you will wonder why you struggled to understand a concept that in reality is incredibly simple. It is awesome when this happens, and when it does, you might find Haskell to be your favorite imperative programming language :)

To make sure that you are understanding Haskell type system perfectly, you should try to solve 20 intermediate haskell exercises. Those exercises using fun names of functions like "furry" and "banana" and helps you to have a good understanding of some basic functional programming concepts if you don't have them already. Nice way to spend your evening with a bunch of papers covered with arrows, unicorns, sausages and furry bananas.

Intermediate

Once you understand Monads, I think you have made the transition from a beginner Haskell programmer to an intermediate haskeller. So where to go from here? The first thing I would recommend (if you haven't already learnt them from learning monads) is the various types of monads, such as Reader, Writer and State. Again, Real world Haskell and All about monads gives great coverage of this. To complete your monad training learning about monad transformers is a must. These let you combine different types of Monads (such as a Reader and State monad) into one. This may seem useless to begin with, but after using them for a while you will wonder how you lived without them.

Now you can finish the real world Haskell book if you want. Skipping chapters now doesn't really matter, as long as you have monads down pat. Just choose what you are interested in.

With the knowledge you would have now, you should be able to use most of the packages on cabal (well the documented ones at least...), as well as most of the libraries that come with Haskell. A list of interesting libraries to try would be:

• Parsec: for parsing programs and text. Much better than using regexps. Excellent documentation, also has a real world Haskell chapter.

• QuickCheck: A very cool testing program. What you do is write a predicate that should always be true (eg length (reverse lst) == length lst). You then pass the predicate the QuickCheck, and it will generate a lot of random values (in this case lists) and test that the predicate is true for all results. See also the online manual.

• HUnit: Unit testing in Haskell.

• gtk2hs: The most popular gui framework for Haskell, lets you write gtk applications.

• happstack: A web development framework for Haskell. Doesn't use databases, instead a data type store. Pretty good docs (other popular frameworks would be snap and yesod).

Also, there are many concepts (like the Monad concept) that you should eventually learn. This will be easier than learning Monads the first time, as your brain will be used to dealing with the level of abstraction involved. A very good overview for learning about these high level concepts and how they fit together is the Typeclassopedia.

• Applicative: An interface like Monads, but less powerful. Every Monad is Applicative, but not vice versa. This is useful as there are some types that are Applicative but are not Monads. Also, code written using the Applicative functions is often more composable than writing the equivalent code using the Monad functions. See Functors, Applicative Functors and Monoids from the learn you a haskell guide.

• Foldable,Traversable: Typeclasses that abstract many of the operations of lists, so that the same functions can be applied to other container types. See also the haskell wiki explanation.

• Monoid: A Monoid is a type that has a zero (or mempty) value, and an operation, notated <> that joins two Monoids together, such that x <> mempty = mempty <> x = x and x <> (y <> z) = (x <> y) <> z. These are called identity and associativity laws. Many types are Monoids, such as numbers, with mempty = 0 and <> = +. This is useful in many situations.

• Arrows: Arrows are a way of representing computations that take an input and return an output. A function is the most basic type of arrow, but there are many other types. The library also has many very useful functions for manipulating arrows - they are very useful even if only used with plain old Haskell functions.

• Arrays: the various mutable/immutable arrays in Haskell.

• ST Monad: lets you write code with a mutable state that runs very quickly, while still remaining pure outside the monad. See the link for more details.

• FRP: Functional Reactive Programming, a new, experimental way of writing code that handles events, triggers, inputs and outputs (such as a gui). I don't know much about this though. Paul Hudak's talk about yampa is a good start.

There are a lot of new language features you should have a look at. I'll just list them, you can find lots of info about them from google, the haskell wikibook, the haskellwiki.org site and ghc documentation.

• Multiparameter type classes/functional dependencies
• Type families
• Existentially quantified types
• Phantom types
• GADTS
• others...

A lot of Haskell is based around category theory, so you may want to look into that. A good starting point is Category Theory for Computer Scientist. If you don't want to buy the book, the author's related article is also excellent.

Finally you will want to learn more about the various Haskell tools. These include:

• ghc (and all its features)
• cabal: the Haskell package system
• darcs: a distributed version control system written in Haskell, very popular for Haskell programs.
• haddock: a Haskell automatic documentation generator

While learning all these new libraries and concepts, it is very useful to be writing a moderate-sized project in Haskell. It can be anything (e.g. a small game, data analyser, website, compiler). Working on this will allow you to apply many of the things you are now learning. You stay at this level for ages (this is where I'm at).

Expert

It will take you years to get to this stage (hello from 2009!), but from here I'm guessing you start writing phd papers, new ghc extensions, and coming up with new abstractions.

Getting Help

Finally, while at any stage of learning, there are multiple places for getting information. These are:

• the #haskell irc channel
• the mailing lists. These are worth signing up for just to read the discussions that take place - some are very interesting.
• other places listed on the haskell.org home page

Conclusion

Well this turned out longer than I expected... Anyway, I think it is a very good idea to become proficient in Haskell. It takes a long time, but that is mainly because you are learning a completely new way of thinking by doing so. It is not like learning Ruby after learning Java, but like learning Java after learning C. Also, I am finding that my object-orientated programming skills have improved as a result of learning Haskell, as I am seeing many new ways of abstracting ideas.

There's a nice overview over some hash algorithms at Eternally Confuzzled. I'd recommend Bob Jenkins' one-at-a-time hash which quickly reaches avalanche and therefore can be used for efficient hash table lookup.

Just goto conf folder of tomcat

open the server.xml file

Goto one of the connector node which look like the following

<Connector port="8080" protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           redirectPort="8443" />

Simply change the port

save and restart tomcat

This did the job for me including active main dropdowns and the active childrens (thanks to 422):

$(document).ready(function () {
    var url = window.location;
    // Will only work if string in href matches with location
    $('ul.nav a[href="' + url + '"]').parent().addClass('active');

    // Will also work for relative and absolute hrefs
    $('ul.nav a').filter(function () {
        return this.href == url;
    }).parent().addClass('active').parent().parent().addClass('active');
});

You forgot to put z as an bind variable.

The following EXECUTE command runs a PL/SQL statement that references a stored procedure:

Note that the value returned by the stored procedure is being return into :Z

I prefer using pip in case you are using virtualenv:

1. apt install libpython2.7 libpython2.7-dev
2. pip install psycopg2

Enable search highlighting:

:set hlsearch

Then search for the word:

/word<Enter>

This won't fail on Linq2Objects, but it will fail for Linq2SQL, so I am assuming that you are talking about the SQL provider or something similar.

The reason has to do with the way that the SQL provider handles your lambda expression. It doesn't take it as a function Func<P,T>, but an expression Expression<Func<P,T>>. It takes that expression tree and translates it so an actual SQL statement, which it sends off to the server.

The translator knows how to handle basic operators, but it doesn't know how to handle methods on objects. It doesn't know that IsNullOrEmpty(x) translates to return x == null || x == string.empty. That has to be done explicitly for the translation to SQL to take place.

My comments on Renaud Bompuis's answer messed up.

Actually, you can use late binding, and the reference to the 11.0 object library is not required.

The following code will work without any references:

 Dim f    As Object 
 Set f = Application.FileDialog(3)

 f.Show 

 MsgBox "file choosen = " & f.SelectedItems.Count 

Note that the above works well in the runtime also.

I have aggregated with Qty wise data and store to dataframe

almo_grp_data = pd.DataFrame({'Qty_cnt' :
almo_slt_models_data.groupby( ['orderDate','Item','State Abv']
          )['Qty'].sum()}).reset_index()

copy your Dataframe column and simply apply

df=data['x']
newdf=df.str.lower()

Just a quick heads-up to anyone else who is losing their mind right now:

https://github.com/tmux/tmux/blob/310f0a960ca64fa3809545badc629c0c166c6cd2/CHANGES#L12

so that's just

 :setw -g mouse

Try calling setWillNotDraw(false) from surfaceCreated:

public void surfaceCreated(SurfaceHolder holder) {
    try {
        setWillNotDraw(false); 
        mycam.setPreviewDisplay(holder);
        mycam.startPreview();
    } catch (Exception e) {
        e.printStackTrace();
        Log.d(TAG,"Surface not created");
    }
}

@Override
protected void onDraw(Canvas canvas) {

    canvas.drawRect(area, rectanglePaint);
    Log.w(this.getClass().getName(), "On Draw Called");
}

and calling invalidate from onTouchEvent:

public boolean onTouch(View v, MotionEvent event) {

    invalidate();
    return true;
}

I had the same problem and got it resolved by deleting .m2 maven repo (C:\Users\user\ .m2)

There are two easy ways:

1. In your cpanel Go to cpanel/ softaculous/ wordpress, under the current installation, you will see the websites you have installed with the wordpress. Click the "edit detail" of the particular website and you will see your SQL database username and password.

2. In your server Access your FTP and view the wp-config.php

There is a brand new version of Jsch up on github: https://github.com/vngx/vngx-jsch Some of the improvements include: comprehensive javadoc, enhanced performance, improved exception handling, and better RFC spec adherence. If you wish to contribute in any way please open an issue or send a pull request.

Hope this one help

Remove the file: C:/Sites/folder/Pids/Server.pids

Explanation In UNIX land at least we usually track the process id (pid) in a file like server.pid. I think this is doing the same thing here. That file was probably left over from a crash.

Bootswatch is a good alternative, but you can also find multiple types of free templates made for ASP.NET MVC that use MDBootstrap (a front-end framework built on top of Bootstrap) here:

ASP.NET MVC MDB Templates

Please incre max_iter to 10000 as default value is 1000. Possibly, increasing no. of iterations will help algorithm to converge. For me it converged and solver was -'lbfgs'

log_reg = LogisticRegression(solver='lbfgs',class_weight='balanced', max_iter=10000)

From APUE, Section 5.14 :

char    good_template[] = "/tmp/dirXXXXXX"; /* right way */
char    *bad_template = "/tmp/dirXXXXXX";   /* wrong way*/

... For the first template, the name is allocated on the stack, because we use an array variable. For the second name, however, we use a pointer. In this case, only the memory for the pointer itself resides on the stack; the compiler arranges for the string to be stored in the read-only segment of the executable. When the mkstemp function tries to modify the string, a segmentation fault occurs.

The quoted text matches @Ciro Santilli 's explanation.

As @Heinzi mentioned the character set of the response should be used.

var encoding = response.CharacterSet == ""
    ? Encoding.UTF8
    : Encoding.GetEncoding(response.CharacterSet);

using (var stream = response.GetResponseStream())
{
    var reader = new StreamReader(stream, encoding);
    var responseString = reader.ReadToEnd();
}

1. open kotlin file in android studio
2. go to tools -> kotlin ->kotlin bytecode
3. in the new window that open beside your kotlin file , click the decompile button . it will create java equivalent of your kotlin file .

I suspect that the line

DataTO.Id = Convert.ToInt64(dataAccCom.GetParameterValue(IDbCmd, "op_Id"));

is causing the problem. Is it possible that the op_Id value is being set to null by the stored procedure?

To Guard against it use the Convert.IsDBNull method. For example:

if (!Convert.IsDBNull(dataAccCom.GetParameterValue(IDbCmd, "op_Id"))
{
 DataTO.Id = Convert.ToInt64(dataAccCom.GetParameterValue(IDbCmd, "op_Id"));
}
else 
{
 DataTO.Id = ...some default value or perform some error case management
}

ZoneId here = ZoneId.of("Europe/Kiev");
ZonedDateTime hereAndNow = Instant.now().atZone(here);
String.format("%tz", hereAndNow);

will give you a standardized string representation like "+0300"

Error Case:

var userListQuery = {
    userId: {
        $in: result
    },
    "isCameraAdded": true
}

( cameraInfo.findtext != "" ) ? searchQuery : userListQuery;

Output:

TypeError: (intermediate value)(intermediate value) is not a function

Fix: You are missing a semi-colon (;) to separate the expressions

userListQuery = {
    userId: {
        $in: result
    },
    "isCameraAdded": true
}; // Without a semi colon, the error is produced

( cameraInfo.findtext != "" ) ? searchQuery : userListQuery;

If you don't have the option to delete the already existing file in the new location, but still need to move and delete from the original location, this renaming trick might work:

string newFileLocation = @"c:\test\Test\SomeFile.txt";

while (File.Exists(newFileLocation)) {
    newFileLocation = newFileLocation.Split('.')[0] + "_copy." + newFileLocation.Split('.')[1];
}
File.Move(@"c:\test\SomeFile.txt", newFileLocation);

This assumes the only '.' in the file name is before the extension. It splits the file in two before the extension, attaches "_copy." in between. This lets you move the file, but creates a copy if the file already exists or a copy of the copy already exists, or a copy of the copy of the copy exists... ;)

The other (and perhaps simplest) option for acheiving a clearfix is to use overflow:hidden; on the containing element. For example

.parent {_x000D_
  background: red;_x000D_
  overflow: hidden;_x000D_
}_x000D_
.segment-a {_x000D_
  float: left;_x000D_
}_x000D_
.segment-b {_x000D_
  float: right;_x000D_
}

<div class="parent">_x000D_
  <div class="segment-a">_x000D_
    Float left_x000D_
  </div>_x000D_
  <div class="segment-b">_x000D_
    Float right_x000D_
  </div>_x000D_
</div>

Of course this can only be used in instances where you never wish the content to overflow.

If you pasted your object into content.json directly, it is invalid JSON. JSON keys and values must be wrapped in double quotes (" not ') unless the value is numeric, boolean, null, or composite (array or object). JSON cannot contain functions or undefined values. Below is your object as valid JSON.

{
  "id": "whatever",
  "name": "start",
  "children": [
    {
      "id": "0.9685",
      "name": " contents:queue"
    },
    {
      "id": "0.79281",
      "name": " contents:mqq_error"
    }
  ]
}

You also had an extra }.

for /f "tokens=* delims= " %%f in (myfile) do

This reads a file line-by-line, removing leading spaces (thanks, jeb).

set line=%%f

sets then the line variable to the line just read and

call :procesToken

calls a subroutine that does something with the line

:processToken

is the start of the subroutine mentioned above.

for /f "tokens=1* delims=/" %%a in ("%line%") do

will then split the line at /, but stopping tokenization after the first token.

echo Got one token: %%a

will output that first token and

set line=%%b

will set the line variable to the rest of the line.

if not "%line%" == "" goto :processToken

And if line isn't yet empty (i.e. all tokens processed), it returns to the start, continuing with the rest of the line.

You have to specify the projectBaseDir if the module name doesn't match you module directory.

Since both your module are located in ".", you can simply add the following to your sonar-project properties:

module1.sonar.projectBaseDir=.
module2.sonar.projectBaseDir=.

Sonar will handle your modules as components of the project:

EDIT

If both of your modules are located in the same source directory, define the same source folder for both and exclude the unwanted packages with sonar.exclusions:

module1.sonar.sources=src/main/java
module1.sonar.exclusions=app2code/**/*

module2.sonar.sources=src/main/java
module2.sonar.exclusions=app1code/**/*

This is another version which really does not have any restrictions (e.g.: special chars when using xml approach, number of records in CTE approach) and it runs much faster based on a test on 10M+ records with source string average length of 4000. Hope this could help.

Create function [dbo].[udf_split] (
    @ListString nvarchar(max),
    @Delimiter  nvarchar(1000),
    @IncludeEmpty bit) 
Returns @ListTable TABLE (ID int, ListValue nvarchar(1000))
AS
BEGIN
    Declare @CurrentPosition int, @NextPosition int, @Item nvarchar(max), @ID int, @L int
    Select @ID = 1,
   @L = len(replace(@Delimiter,' ','^')),
            @ListString = @ListString + @Delimiter,
            @CurrentPosition = 1 
    Select @NextPosition = Charindex(@Delimiter, @ListString, @CurrentPosition)
   While @NextPosition > 0 Begin
   Set  @Item = LTRIM(RTRIM(SUBSTRING(@ListString, @CurrentPosition, @NextPosition-@CurrentPosition)))
   If      @IncludeEmpty=1 or LEN(@Item)>0 Begin 
     Insert Into @ListTable (ID, ListValue) Values (@ID, @Item)
     Set @ID = @ID+1
   End
   Set  @CurrentPosition = @NextPosition+@L
   Set  @NextPosition = Charindex(@Delimiter, @ListString, @CurrentPosition)
  End

Sometimes we ignore a little bit issue which is not a Python or IDE fault its logical error We assumed a file .csv which is not a .csv file its a Excell Worksheet file have a look

When you try to open that file using Import compiler will through the error have a look

To Resolve the issue

open your Target file into Microsoft Excell and save that file in .csv format it is important to note that Encoding is important because it will help you to open the file when you try to open it with

with open('YourTargetFile.csv','r',encoding='UTF-8') as file:

So you are set to go now Try to open your file as this

import csv
with open('plain.csv','r',encoding='UTF-8') as file:
load = csv.reader(file)
for line in load:
    print(line)

As Inian suggested, you should alias python to point to python 3. It is very easy to do, and very easy to switchback, personally i have an alias setup for p2=python2 and p3=python3 as well to save on keystrokes. Read here for more information: How do I create a Bash alias?

Here is an example of doing so for python:

alias python=python3

Like so:

$ python --version
Python 2.7.6
$ python3 --version
Python 3.4.3
$ alias python=python3
$ python --version
Python 3.4.3

I tried as you mentioned, but only first parameter is going through and rest all are appearing in the server as undefined. I am passing JSONWebToken as part of header.

.ajax({
    url: 'api/outletadd',
    type: 'post',
    data: { outletname:outletname , addressA:addressA , addressB:addressB, city:city , postcode:postcode , state:state , country:country , menuid:menuid },
    headers: {
        authorization: storedJWT
    },
    dataType: 'json',
    success: function (data){
        alert("Outlet Created");
    },
    error: function (data){
        alert("Outlet Creation Failed, please try again.");        
    }

    });

The problem is you're not doing anything with the result of replace. In Python strings are immutable so anything that manipulates a string returns a new string instead of modifying the original string.

line[8] = line[8].replace(letter, "")

Three ways based on the same simple instruction:

a). Results as easy as locate (1):

android:focusableInTouchMode="true"

among the configuration of any precedent element in the layout, example:

if your whole layout is composed of:

<ImageView>

<EditTextView>

<EditTextView>

<EditTextView>

then you can write the (1) among ImageView parameters and this will grab android's attention to the ImageView instead of the EditText.

b). In case you have another precedent element than an ImageView you may need to add (2) to (1) as:

android:focusable="true"

c). you can also simply create an empty element at the top of your view elements:

<LinearLayout
  android:focusable="true"
  android:focusableInTouchMode="true"
  android:layout_width="0px"
  android:layout_height="0px" />

This alternative until this point results as the simplest of all I've seen. Hope it helps...

    getcwd(currentPath, FILENAME_MAX);
    strcat(currentPath, "/");
    strcat(currentPath, dit->d_name);

    for(i = 0; i < depth; i++)
      printf ("    ");
    printf("%s (subdirectory)\n", dit->d_name);
    depth++;
    helper(dip, dit, statbuf, currentPath, depth, argv);
  }

  else{
    for(i =0; i < depth; i++)
      printf("    ");
    printf("%s (subdirectory)\n", dit->d_name);
    chdir(currentPath);
    depth++;
    helper(dip, dit, statbuf, currentPath, depth, argv);
  }
}

For someone that might find useful, you can use layout_constraintDimensionRatio im any child view inside a ConstraintLayout and we can define the Height or Width a ratio of the other dimension( at least one must be 0dp either width or heigh) example

 <ImageView
        android:layout_width="wrap_content"
        android:layout_height="0dp"
        android:src="@drawable/top_image"
        app:layout_constraintDimensionRatio="16:9"        
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"/>

in this case the aspect ratio it's 16:9 app:layout_constraintDimensionRatio="16:9" you can find more info HERE

This is a quite confusing way of using Apache configuration directives.

Technically, the first bit is equivalent to

Allow From All

This is because Order Deny,Allow makes the Deny directive evaluated before the Allow Directives. In this case, Deny and Allow conflict with each other, but Allow, being the last evaluated will match any user, and access will be granted.

Now, just to make things clear, this kind of configuration is BAD and should be avoided at all cost, because it borders undefined behaviour.

The Limit sections define which HTTP methods have access to the directory containing the .htaccess file.

Here, GET and POST methods are allowed access, and PUT and DELETE methods are denied access. Here's a link explaining what the various HTTP methods are: http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html

However, it's more than often useless to use these limitations as long as you don't have custom CGI scripts or Apache modules that directly handle the non-standard methods (PUT and DELETE), since by default, Apache does not handle them at all.

It must also be noted that a few other methods exist that can also be handled by Limit, namely CONNECT, OPTIONS, PATCH, PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.

The last bit is also most certainly useless, since any correctly configured Apache installation contains the following piece of configuration (for Apache 2.2 and earlier):

#
# The following lines prevent .htaccess and .htpasswd files from being 
# viewed by Web clients. 
#
<Files ~ "^\.ht">
    Order allow,deny
    Deny from all
    Satisfy all
</Files>

which forbids access to any file beginning by ".ht".

The equivalent Apache 2.4 configuration should look like:

<Files ~ "^\.ht">
    Require all denied
</Files>

The InvalidCastException you are getting is due to SCOPE_IDENTITY being a Decimal(38,0).

You can return it as an int by casting it as follows:

string sql = @"
INSERT INTO [MyTable] ([Stuff]) VALUES (@Stuff);
SELECT CAST(SCOPE_IDENTITY() AS INT)";

int id = connection.Query<int>(sql, new { Stuff = mystuff}).Single();

A simple way to handle an exception on any particular method is:

using Microsoft.AspNetCore.Http;
...

public ActionResult MyAPIMethod()
{
    try
    {
       var myObject = ... something;

       return Json(myObject);
    }
    catch (Exception ex)
    {
        Log.Error($"Error: {ex.Message}");
        return StatusCode(StatusCodes.Status500InternalServerError);
    }         
}

#define NUM_TYPES 4

Using StringUtils from commons lang

A null source string will return null. An empty ("") source string will return the empty string. A null remove string will return the source string. An empty ("") remove string will return the source string.

String str = StringUtils.remove("Test remove", "remove");
System.out.println(str);
//result will be "Test"

For my Android projects I've used the Base64 library from here:

http://iharder.net/base64

It's a very extensive library and so far I've had no problems with it.

You need to

set identity_insert YourTable ON

Then delete your row and reinsert it with different identity.

Once you have done the insert don't forget to turn identity_insert off

set identity_insert YourTable OFF

column_obj != None will produce a IS NOT NULL constraint:

In a column context, produces the clause a != b. If the target is None, produces a IS NOT NULL.

or use isnot() (new in 0.7.9):

Implement the IS NOT operator.

Normally, IS NOT is generated automatically when comparing to a value of None, which resolves to NULL. However, explicit usage of IS NOT may be desirable if comparing to boolean values on certain platforms.

Demo:

>>> from sqlalchemy.sql import column
>>> column('YourColumn') != None
<sqlalchemy.sql.elements.BinaryExpression object at 0x10c8d8b90>
>>> str(column('YourColumn') != None)
'"YourColumn" IS NOT NULL'
>>> column('YourColumn').isnot(None)
<sqlalchemy.sql.elements.BinaryExpression object at 0x104603850>
>>> str(column('YourColumn').isnot(None))
'"YourColumn" IS NOT NULL'

This is an old question and maybe still relate to someone.
Let's say you have string HashMap hash and JsonObject jsonObject.

1) Define key-list.
Example:

ArrayList<String> keyArrayList = new ArrayList<>();  
keyArrayList.add("key0");   
keyArrayList.add("key1");  

2) Create foreach loop, add hash from jsonObject with:

for(String key : keyArrayList){  
    hash.put(key, jsonObject.getString(key));
}

That's my approach, hope it answer the question.

<button onclick="hello()">Click!</button>

<p id="demo" style="background: black; color: aliceblue;">
  hello!!!
</p>

<script>
  function hello()
  {
    (document.getElementById("demo").style.cssText =
      "font-size: 40px; background: #f00; text-align: center;")
  }
</script>

<?php

// Checks if key exists (doesn't care about it's value).
// @link http://php.net/manual/en/function.array-key-exists.php
if (array_key_exists(20120504, $search_array)) {
  echo $search_array[20120504];
}

// Checks against NULL
// @link http://php.net/manual/en/function.isset.php

Using Array.prototype.splice() and splice it until the array has element.

Array.prototype.chunk = function(size) {
    let result = [];
    
    while(this.length) {
        result.push(this.splice(0, size));
    }
        
    return result;
}

const arr = [1, 2, 3, 4, 5, 6, 7, 8, 9];
console.log(arr.chunk(2));

Update

Array.prototype.splice() populates the original array and after performing the chunk() the original array (arr) becomes [].

So if you want to keep the original array untouched, then copy and keep the arr data into another array and do the same thing.

Array.prototype.chunk = function(size) {
  let data = [...this];  
  let result = [];
    
    while(data.length) {
        result.push(data.splice(0, size));
    }

    return result;
}

const arr = [1, 2, 3, 4, 5, 6, 7, 8, 9];
console.log('chunked:', arr.chunk(2));
console.log('original', arr);

P.S: Thanks to @mts-knn for mentioning the matter.

For me, in Python 3, it's working simply in this way:

keep = keep.union((0,1,2,3,4,5,6,7,8,9,10))

I don't know if it may be correct...

use the click event for best compatibility with MSIE

$(document).ready(function() {
    $("input[type=checkbox]").click(function() {
        alert("state changed");
    });
});

The Following:

.show-grid [class*="span"] {

means that all child elements of '.show-grid' with a class that CONTAINS the word 'span' in it will acquire those CSS properties.

<div class="show-grid">
  <div class="span">.span</div>
  <div class="span6">span6</div>
  <div class="attention-span">attention</div>
  <div class="spanish">spanish</div>
  <div class="mariospan">mariospan</div>
  <div class="espanol">espanol</div>

  <div>
    <div class="span">.span</div>
  </div>

  <p class="span">span</p>
  <span class="span">I do GET HIT</span>

  <span>I DO NOT GET HIT since I need a class of 'span'</span>
</div>

<div class="span">I DO NOT GET HIT since I'm outside of .show-grid</span>

All of the elements get hit except for the <span> by itself.

In Regards to Bootstrap:

• span6 : this was Bootstrap 2's scaffolding technique which divided a section into a horizontal grid, based on parts of 12. Thus span6 would have a width of 50%.
• In the current day implementation of Bootstrap (v.3 and v.4), you now use the .col-* classes (e.g. col-sm-6), which also specifies a media breakpoint to handle responsiveness when the window shrinks below a certain size. Check Bootstrap 4.1 and Bootstrap 3.3.7 for more documentation. I would recommend going with a later Bootstrap nowadays

Your can use Django REST framework and python Requests library to Programmatically saving image to Django ImageField

Here is a Example:

import requests


def upload_image():
    # PATH TO DJANGO REST API
    url = "http://127.0.0.1:8080/api/gallery/"

    # MODEL FIELDS DATA
    data = {'first_name': "Rajiv", 'last_name': "Sharma"}

    #  UPLOAD FILES THROUGH REST API
    photo = open('/path/to/photo'), 'rb')
    resume = open('/path/to/resume'), 'rb')
    files = {'photo': photo, 'resume': resume}

    request = requests.post(url, data=data, files=files)
    print(request.status_code, request.reason) 

After Change your Function or Code Follow these two steps.

First Enable CORS Then Deploy API every time.

You could use TidyNet.Tidy to convert the HTML to XHTML, and then use an XML parser.

Another alternative would be to use the builtin engine mshtml:

using mshtml;
...
object[] oPageText = { html };
HTMLDocument doc = new HTMLDocumentClass();
IHTMLDocument2 doc2 = (IHTMLDocument2)doc;
doc2.write(oPageText);

This allows you to use javascript-like functions like getElementById()

For CentOS I used this and it worked please use the following commands:

sudo pip uninstall requests
sudo pip uninstall urllib3
sudo yum remove python-urllib3
sudo yum remove python-requests

(confirm that all those libraries have been removed)

sudo yum install python-urllib3
sudo yum install python-requests

last = Object.keys(obj)[Object.keys(obj).length-1];

where obj is your object

Joining lines with svgs was worth a shot for me, and it worked perfectly... first of all, Scalable Vector Graphics (SVG) is an XML-based vector image format for two-dimensional graphics with support for interactivity and animation. SVG images and their behaviors are defined in XML text files. you can create an svg in HTML using <svg> tag. Adobe Illustrator is one of the best software used to create an complex svgs using paths.

Procedure to join two divs using a line :

1. create two divs and give them any position as you need

   <div id="div1" style="width: 100px; height: 100px; top:0; left:0; background:#e53935 ; position:absolute;"></div>
   <div id="div2" style="width: 100px; height: 100px; top:0; left:300px; background:#4527a0 ; position:absolute;"></div>
   

   (for the sake of explanation I am doing some inline styling but it is always good to make a separate css file for styling)

2. <svg><line id="line1"/></svg>

   Line tag allows us to draw a line between two specified points(x1,y1) and (x2,y2). (for a reference visit w3schools.) we haven't specified them yet. because we will be using jQuery to edit the attributes (x1,y1,x2,y2) of line tag.

3. in <script> tag write

   line1 = $('#line1');   
   div1 = $('#div1');   
   div2 = $('#div2');
   

   I used selectors to select the two divs and line...

   var pos1 = div1.position();
   var pos2 = div2.position();
   

   jQuery position() method allows us to obtain the current position of an element. For more information, visit https://api.jquery.com/position/ (you can use offset() method too)

Now as we have obtained all the positions we need we can draw line as follows...

line1
  .attr('x1', pos1.left)
  .attr('y1', pos1.top)
  .attr('x2', pos2.left)
  .attr('y2', pos2.top);

jQuery .attr() method is used to change attributes of the selected element.

All we did in above line is we changed attributes of line from

x1 = 0
y1 = 0
x2 = 0
y2 = 0

to

x1 = pos1.left
y1 = pos1.top
x2 = pos2.left
y2 = pos2.top

as position() returns two values, one 'left' and other 'top', we can easily access them using .top and .left using the objects (here pos1 and pos2) ...

Now line tag has two distinct co-ordinates to draw line between two points.

Tip: add event listeners as you need to divs

Tip: make sure you import jQuery library first before writing anything in script tag

After adding co-ordinates through JQuery ... It will look something like this

Following snippet is for demonstration purpose only, please follow steps above to get correct solution

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="div1" style="width: 100px; height: 100px; top:0; left:0; background:#e53935 ; position:absolute;"></div>_x000D_
<div id="div2" style="width: 100px; height: 100px; top:0; left:300px; background:#4527a0 ; position:absolute;"></div>_x000D_
<svg width="500" height="500"><line x1="50" y1="50" x2="350" y2="50" stroke="red"/></svg>

If you have just a few places where you wish to create this effect, you can use the following html code that requires no css. Just insert it.

<a href="TARGET URL GOES HERE"><img src="URL OF FIRST IMAGE GOES HERE" 
onmouseover="this.src='URL OF IMAGE ON HOVER GOES HERE'"
onmouseout="this.src='URL OF FIRST IMAGE GOES HERE AGAIN'" /></A>

Be sure to write the quote marks exactly as they are here, or it will not work.

I had a requirement where multiple instances of a console application needed to get an unique integer ID. It is used to identify the instance and assigned at startup. Because the .exe is started by hands, I settled on a solution using the ticks of the start time.

My reasoning was that it would be nearly impossible for the user to start two .exe in the same millisecond. This behavior is deterministic: if you have a collision, you know that the problem was that two instances were started at the same time. Methods depending on hashcode, GUID or random numbers might fail in unpredictable ways.

I set the date to 0001-01-01, add the current time and divide the ticks by 10000 (because I don't set the microseconds) to get a number that is small enough to fit into an integer.

 var now = DateTime.Now;
 var zeroDate = DateTime.MinValue.AddHours(now.Hour).AddMinutes(now.Minute).AddSeconds(now.Second).AddMilliseconds(now.Millisecond);
 int uniqueId = (int)(zeroDate.Ticks / 10000);

EDIT: There are some caveats. To make collisions unlikely, make sure that:

• The instances are started manually (more than one millisecond apart)
• The ID is generated once per instance, at startup
• The ID must only be unique in regard to other instances that are currently running
• Only a small number of IDs will ever be needed

This is an answer to @craq :

I just compiled the file from C source and set it to be executable with chmod. There were no warning or error messages from gcc.

I'm a bit surprised that you had to 'set it to executable' -- my gcc always sets the executable flag itself. This suggests to me that gcc didn't expect this to be the final executable file, or that it didn't expect it to be executable on this system.

Now I've tried to just create the object file, like so:

$ gcc -c -o hello hello.c
$ chmod +x hello

(hello.c is a typical "Hello World" program.) But my error message is a bit different:

$ ./hello
bash: ./hello: cannot execute binary file: Exec format error`

On the other hand, this way, the output of the file command is identical to yours:

$ file hello
hello: ELF 64-bit LSB  relocatable, x86-64, version 1 (SYSV), not stripped

Whereas if I compile correctly, its output is much longer.

$ gcc -o hello hello.c
$ file hello
hello: ELF 64-bit LSB  executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.24, BuildID[sha1]=131bb123a67dd3089d23d5aaaa65a79c4c6a0ef7, not stripped

What I am saying is: I suspect it has something to do with the way you compile and link your code. Maybe you can shed some light on how you do that?

You can also find dependencies version details in package.json file as following:

@mattis is correct that iOS 10 Safari won't allow you to disable pinch to zoom with the user-scalable attribute. However, I got it to disable using preventDefault on the 'gesturestart' event. I've only verified this on Safari in iOS 10.0.2.

document.addEventListener('gesturestart', function (e) {
    e.preventDefault();
});

Bootstrap 4 Solution

<div class="btn-group w-100">
    <button type="button" class="btn">One</button>
    <button type="button" class="btn">Two</button>
    <button type="button" class="btn">Three</button>
</div>

You basically tell the btn-group container to have width 100% by adding w-100 class to it. The buttons inside will fill in the whole space automatically.

You can use the following SQL to compare both date and time -

Select * From temp where mydate > STR_TO_DATE('2009-06-29 04:00:44', '%Y-%m-%d %H:%i:%s');

Attached mysql output when I used same SQL on same kind of table and field that you mentioned in the problem-

It should work perfect.

Here's my docker-compose based solution:

  cron:
    image: alpine:3.10
    command: crond -f -d 8
    depends_on:
      - servicename
    volumes:
      - './conf/cron:/etc/crontabs/root:z'
    restart: unless-stopped

the lines with cron entries are on the ./conf/cron file.

Note: this won't run commands that aren't on the alpine image.

If you want to use the variable as enum, just add the function:

Enum EVehicle {
    Car = 'car',
    Bike = 'bike',
    Truck = 'truck'
}

const getVehicleAsEnum = (vehicleStr:string) => vehicleStr === 'car' ? EVehicle.Car : vehicleStr === 'bike' ? EVehicle.Bike : vehicleStr === 'truck' ? EVehicle.Truck : undefined

And then test:

const vehicleEnum = getVecicleAsEnum(str)
if(vehicleEnum) {
   // do something
}

int() is the Python standard built-in function to convert a string into an integer value. You call it with a string containing a number as the argument, and it returns the number converted to an integer:

>>> int("1") + 1
2

If you know the structure of your list, T1 (that it simply contains lists, only one level), you could do this in Python 3:

T2 = [list(map(int, x)) for x in T1]

In Python 2:

T2 = [map(int, x) for x in T1]

It depends on the class you are using.

Dictionary<(Of <(TKey, TValue>)>) Class For Example Support This

The Dictionary<(Of <(TKey, TValue>)>) generic class provides a mapping from a set of keys to a set of values.

For purposes of enumeration, each item in the dictionary is treated as a KeyValuePair<(Of <(TKey, TValue>)>) structure representing a value and its key. The order in which the items are returned is undefined.

foreach (KeyValuePair kvp in myDictionary) {...}

There isn't any need for any JavaScript or CSS, just three attributes:

<select>
    <option selected disabled hidden>Default Value</option>
    <option>Value 1</option>
    <option>Value 2</option>
    <option>Value 3</option>
    <option>Value 4</option>
</select>

It doesn't show the option at all; it just sets the option's value as the default.

However, if you just don't like a placeholder that's the same color as the rest, you can fix it inline like this:

<!DOCTYPE html>
<html>
    <head>
        <title>Placeholder for select tag drop-down menu</title>
    </head>

    <body onload="document.getElementById('mySelect').selectedIndex = 0">
        <select id="mySelect" onchange="document.getElementById('mySelect').style.color = 'black'"     style="color: gray;    width: 150px;">
          <option value="" hidden>Select your beverage</option> <!-- placeholder -->
          <option value="water" style="color:black" >Water</option>
          <option value="milk" style="color:black" >Milk</option>
          <option value="soda" style="color:black" >Soda</option>
        </select>
    </body>
</html>

Obviously, you can separated the functions and at least the select's CSS into separate files.

Note: the onload function corrects a refresh bug.

I had the same error show up while creating the project but I wasn't behind a proxy and hence the above solutions did not work for me.

I found this forum. It suggested to:

1. Delete or Rename .m2 directory from your HOME directory

In Windows - C:\Users\<username>\Windows

OR

In Linux - /home/<username>

2. restart the Eclipse / STS spring tool suite (which am using)

It worked!

Here is an iterative solution using object-scan. The advantage is that you can easily do other processing in the filter function and specify the paths in a more readable format. There is a trade-off in introducing a dependency though, so it really depends on your use case.

// const objectScan = require('object-scan');

const search = (haystack, k, v) => objectScan([`list[*].${k}`], {
  rtn: 'parent',
  filterFn: ({ value }) => value === v
})(haystack);

const obj = { list: [ { name: 'my Name', id: 12, type: 'car owner' }, { name: 'my Name2', id: 13, type: 'car owner2' }, { name: 'my Name4', id: 14, type: 'car owner3' }, { name: 'my Name4', id: 15, type: 'car owner5' } ] };

console.log(search(obj, 'name', 'my Name'));
// => [ { name: 'my Name', id: 12, type: 'car owner' } ]

.as-console-wrapper {max-height: 100% !important; top: 0}

<script src="https://bundle.run/[email protected]"></script>

Disclaimer: I'm the author of object-scan

int[] and int* are represented the same way, except int[] allocates (IIRC).

ap is a pointer, therefore giving it the value of an integer is dangerous, as you have no idea what's at address 45.

when you try to access it (x = *ap), you try to access address 45, which causes the crash, as it probably is not a part of the memory you can access.

This is possible using the Info-Zip open-source Zip utilities. If unzip is run with the -X parameter, it will attempt to preserve the original permissions. If the source filesystem was NTFS and the destination is a Unix one, it will attempt to translate from one to the other. I do not have a Windows system available right now to test the translation, so you will have to experiment with which group needs to be awarded execute permissions. It'll be something like "Users" or "Any user"

There are many possibilities to solve this task.

1. RUN the batch file with full path

The easiest solution is running the batch file with full path.

"F:\- Big Packets -\kitterengine\Common\Template.bat"

Once end of batch file Template.bat is reached, there is no return to previous script in case of the command line above is within a *.bat or *.cmd file.

The current directory for the batch file Template.bat is the current directory of the current process. In case of Template.bat requires that the directory of this batch file is the current directory, the batch file Template.bat should contain after @echo off as second line the following command line:

cd /D "%~dp0"

Run in a command prompt window cd /? for getting displayed the help of this command explaining parameter /D ... change to specified directory also on a different drive.

Run in a command prompt window call /? for getting displayed the help of this command used also in 2., 4. and 5. solution and explaining also %~dp0 ... drive and path of argument 0 which is the name of the batch file.

2. CALL the batch file with full path

Another solution is calling the batch file with full path.

call "F:\- Big Packets -\kitterengine\Common\Template.bat"

The difference to first solution is that after end of batch file Template.bat is reached the batch processing continues in batch script containing this command line.

For the current directory read above.

3. Change directory and RUN batch file with one command line

There are 3 operators for running multiple commands on one command line: &, && and ||.
For details see answer on Single line with multiple commands using Windows batch file

I suggest for this task the && operator.

cd /D "F:\- Big Packets -\kitterengine\Common" && Template.bat

As on first solution there is no return to current script if this is a *.bat or *.cmd file and changing the directory and continuation of batch processing on Template.bat is successful.

4. Change directory and CALL batch file with one command line

This command line changes the directory and on success calls the batch file.

cd /D "F:\- Big Packets -\kitterengine\Common" && call Template.bat

The difference to third solution is the return to current batch script on exiting processing of Template.bat.

5. Change directory and CALL batch file with keeping current environment with one command line

The four solutions above change the current directory and it is unknown what Template.bat does regarding

1. current directory
2. environment variables
3. command extensions state
4. delayed expansion state

In case of it is important to keep the environment of current *.bat or *.cmd script unmodified by whatever Template.bat changes on environment for itself, it is advisable to use setlocal and endlocal.

Run in a command prompt window setlocal /? and endlocal /? for getting displayed the help of these two commands. And read answer on change directory command cd ..not working in batch file after npm install explaining more detailed what these two commands do.

setlocal & cd /D "F:\- Big Packets -\kitterengine\Common" & call Template.bat & endlocal

Now there is only & instead of && used as it is important here that after setlocal is executed the command endlocal is finally also executed.

ONE MORE NOTE

If batch file Template.bat contains the command exit without parameter /B and this command is really executed, the command process is always exited independent on calling hierarchy. So make sure Template.bat contains exit /B or goto :EOF instead of just exit if there is exit used at all in this batch file.

This is a verbatim string, and changes the escaping rules - the only character that is now escaped is ", escaped to "". This is especially useful for file paths and regex:

var path = @"c:\some\location";
var tsql = @"SELECT *
            FROM FOO
            WHERE Bar = 1";
var escaped = @"a "" b";

etc

Chrome 11 spits out the following in its debugger:

[Error] GET http://www.mypicx.com/images/logo.jpg undefined (undefined)

It looks like that hosting service is using some funky dynamic system that is preventing these browsers from fetching it correctly. (Instead it tries to fetch the default base image, which is problematically a jpeg.) Could you just upload another copy of the image elsewhere? I would expect it to be the easiest solution by a long mile.

Edit: See what happens in Chrome when you place the image using normal <img> tags ;)

I had the same problem, which went away after I listed my library last: gcc prog.c -lm

typedef struct{
     char name[30];
     char surname[30];
     int age;
} data;

defines that data should be a block of memory that fits 60 chars plus 4 for the int (see note)

[----------------------------,------------------------------,----]
 ^ this is name              ^ this is surname              ^ this is age

This allocates the memory on the stack.

data s1;

Assignments just copies numbers, sometimes pointers.

This fails

s1.name = "Paulo";

because the compiler knows that s1.name is the start of a struct 64 bytes long, and "Paulo" is a char[] 6 bytes long (6 because of the trailing \0 in C strings)
Thus, trying to assign a pointer to a string into a string.

To copy "Paulo" into the struct at the point name and "Rossi" into the struct at point surname.

memcpy(s1.name,    "Paulo", 6);
memcpy(s1.surname, "Rossi", 6);
s1.age = 1;

You end up with

[Paulo0----------------------,Rossi0-------------------------,0001]

strcpy does the same thing but it knows about \0 termination so does not need the length hardcoded.

Alternatively you can define a struct which points to char arrays of any length.

typedef struct {
  char *name;
  char *surname;
  int age;
} data;

This will create

[----,----,----]

This will now work because you are filling the struct with pointers.

s1.name = "Paulo";
s1.surname = "Rossi";
s1.age = 1;

Something like this

[---4,--10,---1]

Where 4 and 10 are pointers.

Note: the ints and pointers can be different sizes, the sizes 4 above are 32bit as an example.

From the documentation for ast.literal_eval():

Safely evaluate an expression node or a string containing a Python expression. The string or node provided may only consist of the following Python literal structures: strings, numbers, tuples, lists, dicts, booleans, and None.

Decimal isn't on the list of things allowed by ast.literal_eval().

for me the only thing that works is:

CREATE FUNCTION IsNumeric (SIN VARCHAR(1024)) RETURNS TINYINT

How about:

Random generator = new Random();
int i = 10 - generator.nextInt(10);

1. This is not done in PHP. It's part of the <head> tags in a HTML page.
2. That icon is called a favicon. According to Wikipedia:

   A favicon (short for favorites icon), also known as a shortcut icon, website icon, URL icon, or bookmark icon is a 16×16 or 32×32 pixel square icon associated with a particular website or webpage.

3. Adding it is easy. Just add an .ico image file that is either 16x16 pixels or 32x32 pixels. Then, in the web pages, add <link rel="shortcut icon" href="favicon.ico" type="image/x-icon"> to the <head> element.
4. You can easily generate favicons here.

The most widely compatible way of doing this is likely going to be creating a second div under your auto-suggest box the same size as the box itself, nudged a few pixels down and to the right. You can use JS to create and position it, which shouldn't be terribly difficult if you're using a fairly modern framework.

I was able to get better performance with a text based protocol as compared to protobuff on python. However, no type checking or other fancy utf8 conversion, etc... which protobuff offers.

So, if serialization/deserialization is all you need, then you can probably use something else.

Fixing pip

For this error:

~/Library/Python/2.7/bin/pip: /usr/local/opt/python/bin/python2.7: bad interpreter: No such file or directory`

The source of this problem is a bad python path hardcoded in pip (which means it won't be fixed by e.g. changing your $PATH). That path is no longer hardcoded in the lastest version of pip, so a solution which should work is:

pip install --upgrade pip

But of course, this command uses pip, so it fails with the same error.

The way to bootstrap yourself out of this mess:

1. Run which pip
2. Open that file in a text editor
3. Change the first line from #!/usr/local/opt/python/bin/python2.7 to e.g. #!/usr/local/opt/python2/bin/python2.7 (note the python2 in the path), or any path to a working python interpreter on your machine.
4. Now, pip install --upgrade pip (this overwrites your hack and gets pip working at the latest version, where the interpreter issue should be fixed)

Fixing virtualenv

For me, I found this issue by first having the identical issue from virtualenv:

~/Library/Python/2.7/bin/virtualenv: /usr/local/opt/python/bin/python2.7: bad interpreter: No such file or directory`

The solution here is to run

pip uninstall virtualenv
pip install virtualenv

If running that command gives the same error from pip, see above.

This will alert the index of the clicked selector (starting with 0 for the first):

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

4. goodluck for you,it is ok with gradle 1.2.3

You have to include sort function which is in algorithm header file which is a standard template library in c++.

Usage: std::sort(str.begin(), str.end());

#include <iostream>
#include <algorithm>  // this header is required for std::sort to work
int main()
{
    std::string s = "dacb";
    std::sort(s.begin(), s.end());
    std::cout << s << std::endl;

    return 0;
}

[Updated to adapt to modern pandas, which has isnull as a method of DataFrames..]

You can use isnull and any to build a boolean Series and use that to index into your frame:

>>> df = pd.DataFrame([range(3), [0, np.NaN, 0], [0, 0, np.NaN], range(3), range(3)])
>>> df.isnull()
       0      1      2
0  False  False  False
1  False   True  False
2  False  False   True
3  False  False  False
4  False  False  False
>>> df.isnull().any(axis=1)
0    False
1     True
2     True
3    False
4    False
dtype: bool
>>> df[df.isnull().any(axis=1)]
   0   1   2
1  0 NaN   0
2  0   0 NaN

[For older pandas:]

You could use the function isnull instead of the method:

In [56]: df = pd.DataFrame([range(3), [0, np.NaN, 0], [0, 0, np.NaN], range(3), range(3)])

In [57]: df
Out[57]: 
   0   1   2
0  0   1   2
1  0 NaN   0
2  0   0 NaN
3  0   1   2
4  0   1   2

In [58]: pd.isnull(df)
Out[58]: 
       0      1      2
0  False  False  False
1  False   True  False
2  False  False   True
3  False  False  False
4  False  False  False

In [59]: pd.isnull(df).any(axis=1)
Out[59]: 
0    False
1     True
2     True
3    False
4    False

leading to the rather compact:

In [60]: df[pd.isnull(df).any(axis=1)]
Out[60]: 
   0   1   2
1  0 NaN   0
2  0   0 NaN

Simply replace it with nothing:

var string = 'F0123456'; // just an example
string.replace(/^F0+/i, ''); '123456'

$('.someclass').length

You could also use:

$('.someclass').size()

which is functionally equivalent, but the former is preferred. In fact, the latter is now deprecated and shouldn't be used in any new development.

If you want to compare files visually you can use:

git difftool

It will start your diff app automatically for each changed file.

PS: If you did not set a diff app, you can do it like in the example below(I use Winmerge):

git config --global merge.tool winmerge
git config --replace --global mergetool.winmerge.cmd "\"C:\Program Files (x86)\WinMerge\WinMergeU.exe\" -e -u -dl \"Base\" -dr \"Mine\" \"$LOCAL\" \"$REMOTE\" \"$MERGED\""
git config --global mergetool.prompt false

I hope this may add some more clarity.

!The syntax is
git add <limiters> <pathspec>
! Aka
git add (nil/-u/-A) (nil/./pathspec)

Limiters may be -u or -A or nil.

Pathspec may be a filepath or dot, '.' to indicate the current directory.

Important background knowledge about how Git 'adds':

• Invisible files, those prefixed with a dot, (dotfiles) are never automatically recognized by Git. They are never even listed as 'untracked'.
• Empty folders are never added by Git. They are never even listed as 'untracked'. (A workaround is to add a blank file, possibly invisible, to the tracked files.)
• Git status will not display subfolder information, that is, untracked files, unless at least one file in that subfolder is tracked. Before such time, Git considers the entire folder out of scope, a la 'empty'. It is empty of tracked items.
• Specifying a filespec = '.' (dot), or the current directory, is not recursive unless -A is also specified. Dot refers strictly to the current directory - it omits paths found above and below.

Now, given that knowledge, we can apply the answers above.

The limiters are as follows.

• -u = --update = subset to tracked files => Add = No; Change = Yes; Delete = Yes. => if the item is tracked.
• -A = --all (no such -a, which gives syntax error) = superset of all untracked/tracked files , unless in Git before 2.0, wherein if the dot filespec is given, then only that particular folder is considered. => if the item is recognized, git add -A will find it and add it.

The pathspec is as follows.

• In Git before 2.0, for the two limiters (update and all), the new default is to operate on the entire working tree, instead of the current path (Git 1.9 or earlier),
• However, in v2.0, the operation can be limited to the current path: just add the explicit dot suffix (which is also valid in Git 1.9 or earlier);

git add -A .

git add -u .

In conclusion, my policy is:

1. Ensure any hunks/files to be added are accounted for in git status.
2. If any items are missing, due to invisible files/folders, add them separately.
3. Have a good .gitignore file so that normally only files of interest are untracked and/or unrecognized.
4. From the top level of the repository, "git add -A" to add all items. This works in all versions of Git.
5. Remove any desired items from the index if desired.
6. If there is a big bug, do 'git reset' to clear the index entirely.

If you are building with Eclipse, make sure your project's build target is set to Honeycomb too.

You have to enable the executable bit for the program.

chmod +x script.sh

Then you can use ./script.sh

You can add the folder to the PATH in your .bashrc file (located in your home directory). Add this line to the end of the file:

export PATH=$PATH:/your/folder/here

You can also connect via port 465, but due to some limitations of the System.Net.Mail namespace you may have to alter your code. This is because the namespace does not offer the ability to make implicit SSL connections. This is discussed at http://blogs.msdn.com/b/webdav_101/archive/2008/06/02/system-net-mail-with-ssl-to-authenticate-against-port-465.aspx.

It is possible to make implicit connections without having to use the now obsolete System.Web.Mail namespace, but you have to access the Microsoft CDO (Collaborative Data Object). I have supplied an example of how to use the CDO in another discussion (GMail SMTP via C# .Net errors on all ports).

Hope this helps!

Replace the username and password with Integrated Security=SSPI;

So the connection string should be

<connectionStrings> 
<add name="NorthwindContex" 
   connectionString="data source=localhost;
   initial catalog=northwind;persist security info=True; 
   Integrated Security=SSPI;" 
   providerName="System.Data.SqlClient" /> 
</connectionStrings> 

I know this is an old question, but I just want to throw this out there that you can still use File.Create("filename")", just add .Dispose() to it.

File.Create("filename").Dispose();

This way it creates and closes the file for the next process to use it.

For the react projects with webpack:

1. Do: npm install @babel/plugin-proposal-class-properties --save-dev
2. Create .babelrc (if not present) file in the root folder where package.json and webpack.config.js are present and add below code to that:

{
  "presets": ["@babel/preset-env", "@babel/preset-react"],
  "plugins": [
    [
      "@babel/plugin-proposal-class-properties",
      {
        "loose": true
      }
    ]
  ]
}

3. Add below code to the webpack.config.js file:

{
            test: /\.jsx?$/,
            exclude: /node_modules/,
            loader: 'babel-loader',
            query: {
                presets: ["@babel/preset-env", "@babel/preset-react"]
            },
            resolve: {
                extensions: ['.js', '.jsx']
            }
}

4. Close the terminal and run npm start again.

Use https://github.com/kristerkari/react-native-svg-transformer

In this package it is mentioned that .svg files are not supported in React Native v0.57 and lower so use .svgx extension for svg files.

For web or react-native-web use https://www.npmjs.com/package/@svgr/webpack

To render svg files using react-native-svg-uri with react-native version 0.57 and lower, you need to add following files to your root project

Note: change extension svg to svgx

step 1: add file transformer.js to project's root

// file: transformer.js

const cleanupSvg = require('./cleanup-svg');

const upstreamTransformer = require("metro/src/transformer");

// const typescriptTransformer = require("react-native-typescript-transformer");
// const typescriptExtensions = ["ts", "tsx"];

const svgExtensions = ["svgx"]

// function cleanUpSvg(text) {
//   text = text.replace(/width="([#0-9]+)px"/gi, "");
//    text = text.replace(/height="([#0-9]+)px"/gi, "");
//    return text;
// }

function fixRenderingBugs(content) {
  // content = cleanUpSvg(content); // cleanupSvg removes width and height attributes from svg
  return "module.exports = `" + content + "`";
}


module.exports.transform = function ({ src, filename, options }) {
  // if (typescriptExtensions.some(ext => filename.endsWith("." + ext))) {
  //  return typescriptTransformer.transform({ src, filename, options })
  // }

  if (svgExtensions.some(ext => filename.endsWith("." + ext))) {
    return upstreamTransformer.transform({
      src: fixRenderingBugs(src),
      filename,
      options
    })
  }

  return upstreamTransformer.transform({ src, filename, options });
}

step 2: add rn-cli.config.js to project's root

module.exports = {
    getTransformModulePath() {
      return require.resolve("./transformer");
    },
    getSourceExts() {
      return [/* "ts", "tsx", */ "svgx"];
    }
  };

The above mentioned solutions will work in production apps too ?

1. Open the file using vi myfile.csv
2. Press Escape
3. Type :%s/replaceme/withthis/
4. Type :wq and press Enter

Now you will have the new pattern in your file.

There are two types of JAR files available in Java:

1. Runnable/Executable jar file which contains manifest file. To run a Runnable jar you can use java -jar fileName.jar or java -jar -classpath abc.jar fileName.jar

2. Simple jar file that does not contain a manifest file so you simply run your main class by giving its path java -cp ./fileName.jar MainClass

Using a static in this case is the best way to write secure code.

Yes, statics are generally bad - generally, but in this case, the static is what you want. Since the security context associates a Principal with the currently running thread, the most secure code would access the static from the thread as directly as possible. Hiding the access behind a wrapper class that is injected provides an attacker with more points to attack. They wouldn't need access to the code (which they would have a hard time changing if the jar was signed), they just need a way to override the configuration, which can be done at runtime or slipping some XML onto the classpath. Even using annotation injection would be overridable with external XML. Such XML could inject the running system with a rogue principal.

If you want to do it with a Windows Store App, following by @Hans Kesting and @Jink answer:

    string colorcode = "#FFEEDDCC";
    int argb = Int32.Parse(colorcode.Replace("#", ""), NumberStyles.HexNumber);
    tData.DefaultData = Color.FromArgb((byte)((argb & -16777216) >> 0x18),
                          (byte)((argb & 0xff0000) >> 0x10),
                          (byte)((argb & 0xff00) >> 8),
                          (byte)(argb & 0xff));

How to find error details

Anylyze -> Inspect Code

Then in Inspection Results you will see an error

In my case build failed due to unresolved javadoc reference in Google IAP

Ref and event bus both has issues when your control render is affected by v-if. So, I decided to go with a simpler method.

The idea is using an array as a queue to send methods that needs to be called to the child component. Once the component got mounted, it will process this queue. It watches the queue to execute new methods.

(Borrowing some code from Desmond Lua's answer)

Parent component code:

import ChildComponent from './components/ChildComponent'

new Vue({
  el: '#app',
  data: {
    item: {},
    childMethodsQueue: [],
  },
  template: `
  <div>
     <ChildComponent :item="item" :methods-queue="childMethodsQueue" />
     <button type="submit" @click.prevent="submit">Post</button>
  </div>
  `,
  methods: {
    submit() {
      this.childMethodsQueue.push({name: ChildComponent.methods.save.name, params: {}})
    }
  },
  components: { ChildComponent },
})

This is code for ChildComponent

<template>
 ...
</template>

<script>
export default {
  name: 'ChildComponent',
  props: {
    methodsQueue: { type: Array },
  },
  watch: {
    methodsQueue: function () {
      this.processMethodsQueue()
    },
  },
  mounted() {
    this.processMethodsQueue()
  },
  methods: {
    save() {
        console.log("Child saved...")
    },
    processMethodsQueue() {
      if (!this.methodsQueue) return
      let len = this.methodsQueue.length
      for (let i = 0; i < len; i++) {
        let method = this.methodsQueue.shift()
        this[method.name](method.params)
      }
    },
  },
}
</script>

And there is a lot of room for improvement like moving processMethodsQueue to a mixin...

All the same.

Just another answer to explain some subtle points in the code of the other answers:

• socket.INADDR_ANY - (Edited) In the context of IP_ADD_MEMBERSHIP, this doesn't really bind the socket to all interfaces but just choose the default interface where multicast is up (according to routing table)
• Joining a multicast group isn't the same as binding a socket to a local interface address

see What does it mean to bind a multicast (UDP) socket? for more on how multicast works

    # programs (like another python program instance of this)

    # assert bind_group in groups + [None], \
    #     'bind group not in groups to join'
    sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, socket.IPPROTO_UDP)

    run(args.join_mcast_groups, args.port, args.iface, args.bind_group)

sample usage: (run the below in two consoles and choose your own --iface (must be same as the interface that receives the multicast data))

python3 multicast_recv.py --iface='192.168.56.102' --join-mcast-groups '224.1.1.1' '224.1.1.2' '224.1.1.3' --bind-group '224.1.1.2'

python3 multicast_recv.py --iface='192.168.56.102' --join-mcast-groups '224.1.1.4'

Multicast sender:

import socket
import argparse


def run(group, port):
    MULTICAST_TTL = 20
    sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, socket.IPPROTO_UDP)
    sock.setsockopt(socket.IPPROTO_IP, socket.IP_MULTICAST_TTL, MULTICAST_TTL)
    sock.sendto(b'from multicast_send.py: ' +
                f'group: {group}, port: {port}'.encode(), (group, port))


if __name__ == '__main__':
    parser = argparse.ArgumentParser()
    parser.add_argument('--mcast-group', default='224.1.1.1')
    parser.add_argument('--port', default=19900)
    args = parser.parse_args()
    run(args.mcast_group, args.port)

sample usage: # assume the receiver binds to the below multicast group address and that some program requests to join that group. And to simplify the case, assume the receiver and the sender are under the same subnet

python3 multicast_send.py --mcast-group '224.1.1.2'

python3 multicast_send.py --mcast-group '224.1.1.4'

The action occurs when you attempt to call an object which is not a function, as with (). For instance, this will produce the error:

>>> a = 5
>>> a()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'int' object is not callable

Class instances can also be called if they define a method __call__

One common mistake that causes this error is trying to look up a list or dictionary element, but using parentheses instead of square brackets, i.e. (0) instead of [0]

def func(*args): 
    pass

When you define a function this way, *args will be array of arguments passed to the function. This allows your function to work without knowing ahead of time how many arguments are going to be passed to it.

You do this with keyword arguments too, using **kwargs:

def func2(**kwargs): 
    pass

See: Arbitrary argument lists

In your case, you've defined a class which is acting like a dictionary. The dict.pop method is defined as pop(key[, default]).

Your method doesn't use the default parameter. But, by defining your method with *args and passing *args to dict.pop(), you are allowing the caller to use the default parameter.

In other words, you should be able to use your class's pop method like dict.pop:

my_a = a()
value1 = my_a.pop('key1')       # throw an exception if key1 isn't in the dict
value2 = my_a.pop('key2', None) # return None if key2 isn't in the dict

or a single select statement...

DECLARE @results VarChar(1000)
SELECT @results = CASE
     WHEN @results IS NULL THEN CONVERT( VarChar(20), [StudentId])
     ELSE ', ' + CONVERT( VarChar(20), [StudentId])
   END
FROM Student WHERE condition = abc;

You can leave the script running in background and you can simply filter the logs from the text file the way you want anytime.

I got into a situation where the data was mixed between NULL and 0000-00-00 for a date field. But I did not know how to update the '0000-00-00' to NULL, because

 update my_table set my_date_field=NULL where my_date_field='0000-00-00'

is not allowed any more. My workaround was quite simple:

update my_table set my_date_field=NULL where my_date_field<'1000-01-01'

because all the incorrect my_date_field values (whether correct dates or not) were from before this date.

You can center a box both vertically and horizontally, using the following technique :

The outher container :

• should have display: table;

The inner container :

• should have display: table-cell;
• should have vertical-align: middle;
• should have text-align: center;

The content box :

• should have display: inline-block;

If you use this technique, just add your table (along with any other content you want to go with it) to the content box.

Quick and dirty - Turn it off:

USE_TZ = False

in your settings.py

To let your shell expand the variable, you need to use double-quotes like

sed -i "s#12345678#$replace#g" file.txt

This will break if $replace contain special sed characters (#, \). But you can preprocess $replace to quote them:

replace_quoted=$(printf '%s' "$replace" | sed 's/[#\]/\\\0/g')
sed -i "s#12345678#$replace_quoted#g" file.txt

The decision to use 1st January 1753 (1753-01-01) as the minimum date value for a datetime in SQL Server goes back to its Sybase origins.

The significance of the date itself though can be attributed to this man.

Philip Stanhope, 4th Earl of Chesterfield. Who steered the Calendar (New Style) Act 1750 through the British Parliament. This legislated for the adoption of the Gregorian calendar for Britain and its then colonies.

There were some missing days _{(internet archive link)} in the British calendar in 1752 when the adjustment was finally made from the Julian calendar. September 3, 1752 to September 13, 1752 were lost.

Kalen Delaney explained the choice this way

So, with 12 days lost, how can you compute dates? For example, how can you compute the number of days between October 12, 1492, and July 4, 1776? Do you include those missing 12 days? To avoid having to solve this problem, the original Sybase SQL Server developers decided not to allow dates before 1753. You can store earlier dates by using character fields, but you can't use any datetime functions with the earlier dates that you store in character fields.

The choice of 1753 does seem somewhat anglocentric however as many catholic countries in Europe had been using the calendar for 170 years before the British implementation (originally delayed due to opposition by the church). Conversely many countries did not reform their calendars until much later, 1918 in Russia. Indeed the October Revolution of 1917 started on 7 November under the Gregorian calendar.

Both datetime and the new datetime2 datatype mentioned in Joe's answer do not attempt to account for these local differences and simply use the Gregorian Calendar.

So with the greater range of datetime2

SELECT CONVERT(VARCHAR, DATEADD(DAY,-5,CAST('1752-09-13' AS DATETIME2)),100)

Returns

Sep  8 1752 12:00AM

One final point with the datetime2 data type is that it uses the proleptic Gregorian calendar projected backwards to well before it was actually invented so is of limited use in dealing with historic dates.

This contrasts with other Software implementations such as the Java Gregorian Calendar class which defaults to following the Julian Calendar for dates until October 4, 1582 then jumping to October 15, 1582 in the new Gregorian calendar. It correctly handles the Julian model of leap year before that date and the Gregorian model after that date. The cutover date may be changed by the caller by calling setGregorianChange().

A fairly entertaining article discussing some more peculiarities with the adoption of the calendar can be found here.

If you want distinct values from only two fields, plus return other fields with them, then the other fields must have some kind of aggregation on them (sum, min, max, etc.), and the two columns you want distinct must appear in the group by clause. Otherwise, it's just as Decker says.

$(window).scroll(function() {    
    var scroll = $(window).scrollTop();

     //>=, not <=
    if (scroll >= 500) {
        //clearHeader, not clearheader - caps H
        $(".clearHeader").addClass("darkHeader");
    }
}); //missing );

Fiddle

Also, by removing the clearHeader class, you're removing the position:fixed; from the element as well as the ability of re-selecting it through the $(".clearHeader") selector. I'd suggest not removing that class and adding a new CSS class on top of it for styling purposes.

And if you want to "reset" the class addition when the users scrolls back up:

$(window).scroll(function() {    
    var scroll = $(window).scrollTop();

    if (scroll >= 500) {
        $(".clearHeader").addClass("darkHeader");
    } else {
        $(".clearHeader").removeClass("darkHeader");
    }
});

Fiddle

edit: Here's version caching the header selector - better performance as it won't query the DOM every time you scroll and you can safely remove/add any class to the header element without losing the reference:

$(function() {
    //caches a jQuery object containing the header element
    var header = $(".clearHeader");
    $(window).scroll(function() {
        var scroll = $(window).scrollTop();

        if (scroll >= 500) {
            header.removeClass('clearHeader').addClass("darkHeader");
        } else {
            header.removeClass("darkHeader").addClass('clearHeader');
        }
    });
});

Nothing Worked for me.

I recommend you start reading the documentation (4.6.18. Formatting cells). When applying a lot of formatting it's better to use applyFromArray() According to the documentation this method is also suppose to be faster when you're setting many style properties. There's an annex where you can find all the possible keys for this function.

This will work for you:

$phpExcel = new PHPExcel();

$styleArray = array(
    'font'  => array(
        'bold'  => true,
        'color' => array('rgb' => 'FF0000'),
        'size'  => 15,
        'name'  => 'Verdana'
    ));

$phpExcel->getActiveSheet()->getCell('A1')->setValue('Some text');
$phpExcel->getActiveSheet()->getStyle('A1')->applyFromArray($styleArray);

To apply font style to complete excel document:

 $styleArray = array(
   'font'  => array(
        'bold'  => true,
        'color' => array('rgb' => 'FF0000'),
        'size'  => 15,
        'name'  => 'Verdana'
    ));      
 $phpExcel->getDefaultStyle()
    ->applyFromArray($styleArray);

one line version: (i is an old dictionary, p is a reversed dictionary)

explanation : i.keys() and i.values() returns two lists with keys and values of the dictionary respectively. The zip function has the ability to tie together lists to produce a dictionary.

p = dict(zip(i.values(),i.keys()))

Warning : This will work only if the values are hashable and unique.

Building further on Nick's answer:

$("#myDiv").css({'position':'absolute','visibility':'hidden', 'display':'block'});
optionHeight = $("#myDiv").height();
$("#myDiv").css({'position':'static','visibility':'visible', 'display':'none'});

I found it's better to do this:

$("#myDiv").css({'position':'absolute','visibility':'hidden', 'display':'block'});
optionHeight = $("#myDiv").height();
$("#myDiv").removeAttr('style');

Setting CSS attributes will insert them inline, which will overwrite any other attributes you have in your CSS file. By removing the style attribute on the HTML element, everything is back to normal and still hidden, since it was hidden in the first place.

You can use DataFrame.select_dtypes to select string columns and then apply function str.strip.

Notice: Values cannot be types like dicts or lists, because their dtypes is object.

df_obj = df.select_dtypes(['object'])
print (df_obj)
0    a  
1    c  

df[df_obj.columns] = df_obj.apply(lambda x: x.str.strip())
print (df)

   0   1
0  a  10
1  c   5

But if there are only a few columns use str.strip:

df[0] = df[0].str.strip()

If you're using .NET 3.5 or .NET 4, it's easy to create the dictionary using LINQ:

Dictionary<string, ArrayList> result = target.GetComponents()
                                      .ToDictionary(x => x.Key, x => x.Value);

There's no such thing as an IEnumerable<T1, T2> but a KeyValuePair<TKey, TValue> is fine.

1 way to handle this you can provide login details with url. e.g. if your url is "http://localhost:4040" and it's asking "Username" and "Password" on alert prompt message then you can pass baseurl as "http://username:password@localhost:4040". Hope it works

You can also misuse File.list(FilenameFilter) (and variants) for file traversal. Short code and works in early java versions, e.g:

// list files in dir
new File(dir).list(new FilenameFilter() {
    public boolean accept(File dir, String name) {
        String file = dir.getAbsolutePath() + File.separator + name;
        System.out.println(file);
        return false;
    }
});

I got it to work by doing this, assuming you are using PDO.

//Place query here, let's say you want all the users that have blue as their favorite color
$sql = "SELECT name FROM user WHERE favorite_color = :color";

//set parameters 
//you may set as many parameters as you have on your query
$params['color'] = blue;


//create the prepared statement, by getting the doctrine connection
$stmt = $this->entityManager->getConnection()->prepare($sql);
$stmt->execute($params);
//I used FETCH_COLUMN because I only needed one Column.
return $stmt->fetchAll(PDO::FETCH_COLUMN);

You can change the FETCH_TYPE to suit your needs.

I was in a predicament where I had a signed byte array (sbyte[]) as input to a Test class and I wanted to replace it with a normal byte array (byte[]) for simplicity. I arrived here from a Google search but Tom's answer wasn't useful to me.

I wrote a helper method to print out the initializer of a given byte[]:

public void PrintByteArray(byte[] bytes)
{
    var sb = new StringBuilder("new byte[] { ");
    foreach (var b in bytes)
    {
        sb.Append(b + ", ");
    }
    sb.Append("}");
    Console.WriteLine(sb.ToString());
}

You can use it like this:

var signedBytes = new sbyte[] { 1, 2, 3, -1, -2, -3, 127, -128, 0, };
var unsignedBytes = UnsignedBytesFromSignedBytes(signedBytes);
PrintByteArray(unsignedBytes);
// output:
// new byte[] { 1, 2, 3, 255, 254, 253, 127, 128, 0, }

The ouput is valid C# which can then just be copied into your code.

And just for completeness, here is the UnsignedBytesFromSignedBytes method:

// http://stackoverflow.com/a/829994/346561
public static byte[] UnsignedBytesFromSignedBytes(sbyte[] signed)
{
    var unsigned = new byte[signed.Length];
    Buffer.BlockCopy(signed, 0, unsigned, 0, signed.Length);
    return unsigned;
}

Make sure to learn from the padding oracle asp.net vulnerability that just happened (you applied the patch, right? ...) and use protected sections to encrypt the machine key and any other sensitive configuration.

An alternative option is to set it in the machine level web.config, so its not even in the web site folder.

To generate it do it just like the linked article in David's answer.

Use the below code. This should work.

$comments = EmailArchive::find()->where(['email_id' => $id])->all();

Try to follow the advice you see on the screen, and first reset your master's HEAD to the commit it expects.

git update-ref refs/heads/master b918ac16a33881ce00799bea63d9c23bf7022d67

Then, abort the rebase again.

I hope you cant wait till apple gives you what ever you need right? So here is my option.

Create a custom cell. Have two uiviews in it

1. upper
2. lower

In lower view, add what ever buttons you need. Deal its actions just like any other IBActions. you can decide the animation time, style and anything.

now add a uiswipegesture to the upper view and reveal your lower view on swipe gesture. I have done this before and its the simplest option as far as I am concerned.

Hope that help.

This is a common question in Material Design as you may want to line your toolbars title with the content in the fragment below. To do this, you can override the default padding of "12dp" by using the attribute contentInsetStart="72dp" in your toolbar.xml layout as shown below

toolbar.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/app_theme_color"
    app:contentInsetStart="72dp"/>

Then in your activity, call

Toolbar toolbar = (Toolbar) activity.findViewById(R.id.toolbar);
toolbar.setTitle("Title Goes Here");

And you end up with this:

The accepted answer gethostname() may infact give you inaccurate value as in my case

gethostname()         = my-macbook-pro     (incorrect)
$_SERVER['host_name'] = mysite.git         (correct)

The value from gethostname() is obvsiously wrong. Be careful with it.

Update as corrected by the comment

Host name gives you computer name, not website name, my bad. My result on local machine is

gethostname()         = my-macbook-pro     (which is my machine name)

This concludes that the length of String is limited by the number of bytes of the modified UTF-8 representation of the string when used with DataInput and DataOutput.

In addition, The specification of CONSTANT_Utf8_info found in the Java virtual machine specification defines the structure as follows.

CONSTANT_Utf8_info {
    u1 tag;
    u2 length;
    u1 bytes[length];
}

You can find that the size of 'length' is two bytes.

That the return type of a certain method (e.g. String.length()) is int does not always mean that its allowed maximum value is Integer.MAX_VALUE. Instead, in most cases, int is chosen just for performance reasons. The Java language specification says that integers whose size is smaller than that of int are converted to int before calculation (if my memory serves me correctly) and it is one reason to choose int when there is no special reason.

The maximum length at compilation time is at most 65536. Note again that the length is the number of bytes of the modified UTF-8 representation, not the number of characters in a String object.

String objects may be able to have much more characters at runtime. However, if you want to use String objects with DataInput and DataOutput interfaces, it is better to avoid using too long String objects. I found this limitation when I implemented Objective-C equivalents of DataInput.readUTF() and DataOutput.writeUTF(String).

I have no idea what linux distribution "ubuntu centOS" is. Ubuntu and CentOS are two different distributions.

To answer the question in the header: To install make in ubuntu you have to install build-essentials

sudo apt-get install build-essential

Change column type to LONGTEXT

Just for someone looking for a solution more similar to R:

df[(df.Product == p_id) & (df.Time> start_time) & (df.Time < end_time)][['Time','Product']]

No need for data.loc or query, but I do think it is a bit long.

This removes html code or php if you supplement it. Allows you to add trailing slash and it come up as well as the url without the trailing slash all bypassing the 404 code. Plus a little added security.

I realize this is a somewhat older question, but I just wanted to point out that you've add the model variable to your test widget class incorrectly. If you need a Model variable, you shouldn't be trying to pass it in through the component constructor. You are only intended to pass services or other types of injectables that way. If you are instantiating your test widget inside of another component and need to pass a model object as, I would recommend using the angular core OnInit and Input/Output design patterns.

As an example, your code should really look something like this:

import { Component, Input, OnInit } from "@angular/core";
import { YourModelLoadingService } from "../yourModuleRootFolderPath/index"

class Model {
    param1: string;
}

@Component({
    selector: "testWidget",
    template: "<div>This is a test and {{model.param1}} is my param.</div>",
    providers: [ YourModelLoadingService ]
})

export class testWidget implements OnInit {
    @Input() model: Model; //Use this if you want the parent component instantiating this
        //one to be able to directly set the model's value
    private _model: Model; //Use this if you only want the model to be private within
        //the component along with a service to load the model's value
    constructor(
        private _yourModelLoadingService: YourModelLoadingService //This service should
        //usually be provided at the module level, not the component level
    ) {}

    ngOnInit() {
        this.load();
    }

    private load() {
        //add some code to make your component read only,
        //possibly add a busy spinner on top of your view
        //This is to avoid bugs as well as communicate to the user what's
        //actually going on

        //If using the Input model so the parent scope can set the contents of model,
        //add code an event call back for when model gets set via the parent
        //On event: now that loading is done, disable read only mode and your spinner
        //if you added one

        //If using the service to set the contents of model, add code that calls your
        //service's functions that return the value of model
        //After setting the value of model, disable read only mode and your spinner
        //if you added one. Depending on if you leverage Observables, or other methods
        //this may also be done in a callback
    }
}

A class which is essentially just a struct/model should not be injected, because it means you can only have a single shared instanced of that class within the scope it was provided. In this case, that means a single instance of Model is created by the dependency injector every time testWidget is instantiated. If it were provided at the module level, you would only have a single instance shared among all components and services within that module.

Instead, you should be following standard Object Oriented practices and creating a private model variable as part of the class, and if you need to pass information into that model when you instantiate the instance, that should be handled by a service (injectable) provided by the parent module. This is how both dependency injection and communication is intended to be performed in angular.

Also, as some of the other mentioned, you should be declaring your model classes in a separate file and importing the class.

I would strongly recommend going back to the angular documentation reference and reviewing the basics pages on the various annotations and class types: https://angular.io/guide/architecture

You should pay particular attention to the sections on Modules, Components and Services/Dependency Injection as these are essential to understanding how to use Angular on an architectural level. Angular is a very architecture heavy language because it is so high level. Separation of concerns, dependency injection factories and javascript versioning for browser comparability are mainly handled for you, but you have to use their application architecture correctly or you'll find things don't work as you expect.

This is another way to specify the range of the bit-vector.

x +: N, The start position of the vector is given by x and you count up from x by N.

There is also

x -: N, in this case the start position is x and you count down from x by N.

N is a constant and x is an expression that can contain iterators.

It has a couple of benefits -

1. It makes the code more readable.

2. You can specify an iterator when referencing bit-slices without getting a "cannot have a non-constant value" error.

I always use multiple statements with "-e"

$ sed -e 's:AND:\n&:g' -e 's:GROUP BY:\n&:g' -e 's:UNION:\n&:g' -e 's:FROM:\n&:g' file > readable.sql

This will append a '\n' before all AND's, GROUP BY's, UNION's and FROM's, whereas '&' means the matched string and '\n&' means you want to replace the matched string with an '\n' before the 'matched'

Although this isn't an answer to the OP, I had the exact same error from a completely different root cause; so in case this helps anybody else...

The problem for me was an incorrectly named method parameter which caused WebAPI to route the request unexpectedly. I have the following methods in my ProgrammesController:

[HttpGet]
public Programme GetProgrammeById(int id)
{
    ...
}

[HttpDelete]
public bool DeleteProgramme(int programmeId)
{
    ...
}

DELETE requests to .../api/programmes/3 were not getting routed to DeleteProgramme as I expected, but to GetProgrammeById, because DeleteProgramme didn't have a parameter name of id. GetProgrammeById was then of course rejecting the DELETE as it is marked as only accepting GETs.

So the fix was simple:

[HttpDelete]
public bool DeleteProgramme(int id)
{
    ...
}

And all is well. Silly mistake really but hard to debug.
