Short answer: While it's technically possible to send 100k e-mails each week yourself, the simplest, easiest and cheapest solution is to outsource this to one of the companies that specialize in it (I did say "cheapest": there's no limit to the amount of development time (and therefore money) that you can sink into this when trying to DIY).

Long answer: If you decide that you absolutely want to do this yourself, prepare for a world of hurt (after all, this is e-mail/e-fail we're talking about). You'll need:

• e-mail content that is not spam (otherwise you'll run into additional major roadblocks on every step, even legal repercussions)
• in addition, your content should be easy to distinguish from spam - that may be a bit hard to do in some cases (I heard that a certain pharmaceutical company had to all but abandon e-mail, as their brand names are quite common in spams)
• a configurable SMTP server of your own, one which won't buckle when you dump 100k e-mails onto it (your ISP's upstream server won't be sufficient here and you'll make the ISP violently unhappy; we used two dedicated boxes)
• some mail wrapper (e.g. PhpMailer if PHP's your poison of choice; using PHP's mail() is horrible enough by itself)
• your own sender function to run in a loop, create the mails and pass them to the wrapper (note that you may run into PHP's memory limits if your app has a memory leak; you may need to recycle the sending process periodically, or even better, decouple the "creating e-mails" and "sending e-mails" altogether)

Surprisingly, that was the easy part. The hard part is actually sending it:

• some servers will ban you when you send too many mails close together, so you need to shuffle and watch your queue (e.g. send one mail to [email protected], then three to other domains, only then another to [email protected])
• you need to have correct PTR, SPF, DKIM records
• handling remote server timeouts, misconfigured DNS records and other network pleasantries
• handling invalid e-mails (and no, regex is the wrong tool for that)
• handling unsubscriptions (many legitimate newsletters have been reclassified as spam due to many frustrated users who couldn't unsubscribe in one step and instead chose to "mark as spam" - the spam filters do learn, esp. with large e-mail providers)
• handling bounces and rejects ("no such mailbox [email protected]","mailbox [email protected] full")
• handling blacklisting and removal from blacklists (Sure, you're not sending spam. Some recipients won't be so sure - with such large list, it will happen sometimes, no matter what precautions you take. Some people (e.g. your not-so-scrupulous competitors) might even go as far to falsely report your mailings as spam - it does happen. On average, it takes weeks to get yourself removed from a blacklist.)

And to top it off, you'll have to manage the legal part of it (various federal, state, and local laws; and even different tangles of laws once you send outside the U.S. (note: you have no way of finding if [email protected] lives in Southwest Elbonia, the country with world's most draconian antispam laws)).

I'm pretty sure I missed a few heads of this hydra - are you still sure you want to do this yourself? If so, there'll be another wave, this time merely the annoying problems inherent in sending an e-mail. (You see, SMTP is a store-and-forward protocol, which means that your e-mail will be shuffled across many SMTP servers around the Internet, in the hope that the next one is a bit closer to the final recipient. Basically, the e-mail is sent to an SMTP server, which puts it into its forward queue; when time comes, it will forward it further to a different SMTP server, until it reaches the SMTP server for the given domain. This forward could happen immediately, or in a few minutes, or hours, or days, or never.) Thus, you'll see the following issues - most of which could happen en route as well as at the destination:

• the remote SMTP servers don't want to talk to your SMTP server
• your mails are getting marked as spam (<blink> is not your friend here, nor is <font color=...>)
• your mails are delivered days, even weeks late (contrary to popular opinion, SMTP is designed to make a best effort to deliver the message sometime in the future - not to deliver it now)
• your mails are not delivered at all (already sent from e-mail server on hop #4, not sent yet from server on hop #5, the server that currently holds the message crashes, data is lost)
• your mails are mangled by some braindead server en route (this one is somewhat solvable with base64 encoding, but then the size goes up and the e-mail looks more suspicious)
• your mails are delivered and the recipients seem not to want them ("I'm sure I didn't sign up for this, I remember exactly what I did a year ago" (of course you do, sir))
• users with various versions of Microsoft Outlook and its special handling of Internet mail
• wizard's apprentice mode (a self-reinforcing positive feedback loop - in other words, automated e-mails as replies to automated e-mails as replies to...; you really don't want to be the one to set this off, as you'd anger half the internet at yourself)

and it'll be your job to troubleshoot and solve this (hint: you can't, mostly). The people who run a legit mass-mailing businesses know that in the end you can't solve it, and that they can't solve it either - and they have the reasons well researched, documented and outlined (maybe even as a Powerpoint presentation - complete with sounds and cool transitions - that your bosses can understand), as they've had to explain this a million times before. Plus, for the problems that are actually solvable, they know very well how to solve them.

If, after all this, you are not discouraged and still want to do this, go right ahead: it's even possible that you'll find a better way to do this. Just know that the road ahead won't be easy - sending e-mail is trivial, getting it delivered is hard.

This means that Jupyter is still running the kernel. It is possible that you are running an infinite loop within the kernel and that is why it can't complete the execution.

Try manually stopping the kernel by pressing the stop button at the top. If that doesn't work, interrupt it and restart it by going to the "Kernel" menu. This should disconnect it.

Otherwise, I would recommend closing and reopening the notebook. The problem may also be with your code.

Steve Ebersole & other members,
Would you kindly explain the reason for an id with a larger gap(by default 50)? I am using Hibernate 4.2.15 and found the following code in org.hibernate.id.enhanced.OptimizerFactory cass.

if ( lo > maxLo ) {
   lastSourceValue = callback.getNextValue();
   lo = lastSourceValue.eq( 0 ) ? 1 : 0;
   hi = lastSourceValue.copy().multiplyBy( maxLo+1 ); 
}  
value = hi.copy().add( lo++ );

Whenever it hits the inside of the if statement, hi value is getting much larger. So, my id during the testing with the frequent server restart generates the following sequence ids:
1, 2, 3, 4, 19, 250, 251, 252, 400, 550, 750, 751, 752, 850, 1100, 1150.

I know you already said it didn't conflict with the spec, but I believe this will be very unexpected situation for most developers.

Anyone's input will be much helpful.

Jihwan

UPDATE: ne1410s: Thanks for the edit.
cfrick: OK. I will do that. It was my first post here and wasn't sure how to use it.

Now, I understood better why maxLo was used for two purposes: Since the hibernate calls the DB sequence once, keep increase the id in Java level, and saves it to the DB, the Java level id value should consider how much was changed without calling the DB sequence when it calls the sequence next time.

For example, sequence id was 1 at a point and hibernate entered 5, 6, 7, 8, 9 (with allocationSize = 5). Next time, when we get the next sequence number, DB returns 2, but hibernate needs to use 10, 11, 12... So, that is why "hi = lastSourceValue.copy().multiplyBy( maxLo+1 )" is used to get a next id 10 from the 2 returned from the DB sequence. It seems only bothering thing was during the frequent server restart and this was my issue with the larger gap.

So, when we use the SEQUENCE ID, the inserted id in the table will not match with the SEQUENCE number in DB.

See if this answer can help you. Particularly the fact that CLI ini could be different than when the script is running through a browser.

Easy. Use a bitwise AND to compare your number with the value 2^bitNumber, which can be cheaply calculated by bit-shifting.

//your black magic
var bit = (b & (1 << bitNumber-1)) != 0;

EDIT: To add a little more detail because there are a lot of similar answers with no explanation:

A bitwise AND compares each number, bit-by-bit, using an AND join to produce a number that is the combination of bits where both the first bit and second bit in that place were set. Here's the logic matrix of AND logic in a "nibble" that shows the operation of a bitwise AND:

  0101
& 0011
  ----
  0001 //Only the last bit is set, because only the last bit of both summands were set

In your case, we compare the number you passed with a number that has only the bit you want to look for set. Let's say you're looking for the fourth bit:

  11010010
& 00001000
  --------
  00000000 //== 0, so the bit is not set

  11011010
& 00001000
  --------
  00001000 //!= 0, so the bit is set

Bit-shifting, to produce the number we want to compare against, is exactly what it sounds like: take the number, represented as a set of bits, and shift those bits left or right by a certain number of places. Because these are binary numbers and so each bit is one greater power-of-two than the one to its right, bit-shifting to the left is equivalent to doubling the number once for each place that is shifted, equivalent to multiplying the number by 2^x. In your example, looking for the fourth bit, we perform:

       1 (2^0) << (4-1) ==        8 (2^3)
00000001       << (4-1) == 00001000

Now you know how it's done, what's going on at the low level, and why it works.

The book is a bit dated with respect to subclass-superclass calling. It's also a little dated with respect to subclassing built-in classes.

It looks like this nowadays:

class FileInfo(dict):
    """store file metadata"""
    def __init__(self, filename=None):
        super(FileInfo, self).__init__()
        self["name"] = filename

Note the following:

1. We can directly subclass built-in classes, like dict, list, tuple, etc.

2. The super function handles tracking down this class's superclasses and calling functions in them appropriately.

this is how I do it

JAVASCRIPT:

var module = angular.module('yourModuleName', ['ui.router']);

module.run( ['$rootScope', '$state', '$stateParams',
                      function ($rootScope,   $state,   $stateParams) {
    $rootScope.$state = $state;
    $rootScope.$stateParams = $stateParams; 
}
]);

HTML:

<pre id="uiRouterInfo">
      $state = {{$state.current.name}}
      $stateParams = {{$stateParams}}
      $state full url = {{ $state.$current.url.source }}    
</pre>

The solutions like cmd /c pause cause a new command interpreter to start and run in the background. Although acceptable in some cases, this isn't really ideal.

The solutions using Read-Host force the user to press Enter and are not really "any key".

This solution will give you a true "press any key to continue" interface and will not start a new interpreter, which will essentially mimic the original pause command.

Write-Host "Press any key to continue..."

Good news! Swift 4.2 (Xcode 10) finally provides CommonCrypto!

Just add import CommonCrypto in your swift file.

Why controllers are needed

The difference between link and controller comes into play when you want to nest directives in your DOM and expose API functions from the parent directive to the nested ones.

From the docs:

Best Practice: use controller when you want to expose an API to other directives. Otherwise use link.

Say you want to have two directives my-form and my-text-input and you want my-text-input directive to appear only inside my-form and nowhere else.

In that case, you will say while defining the directive my-text-input that it requires a controller from the parent DOM element using the require argument, like this: require: '^myForm'. Now the controller from the parent element will be injected into the link function as the fourth argument, following $scope, element, attributes. You can call functions on that controller and communicate with the parent directive.

Moreover, if such a controller is not found, an error will be raised.

Why use link at all

There is no real need to use the link function if one is defining the controller since the $scope is available on the controller. Moreover, while defining both link and controller, one does need to be careful about the order of invocation of the two (controller is executed before).

However, in keeping with the Angular way, most DOM manipulation and 2-way binding using $watchers is usually done in the link function while the API for children and $scope manipulation is done in the controller. This is not a hard and fast rule, but doing so will make the code more modular and help in separation of concerns (controller will maintain the directive state and link function will maintain the DOM + outside bindings).

SELECT pid, cid, pname, name1, name2 
FROM customer1 c1, product p 
WHERE p.cid=c1.cid 
UNION SELECT pid, cid, pname, name1, name2 
FROM customer2 c2, product p 
WHERE p.cid=c2.cid;

Apparently, _JAVA_OPTIONS works on Linux, too:

$ export _JAVA_OPTIONS="-Xmx1g"
$ java -jar jconsole.jar &
Picked up _JAVA_OPTIONS: -Xmx1g

to indent a ul dropdown menu, use

/* Main Level */
ul{
  margin-left:10px;
}

/* Second Level */
ul ul{
  margin-left:15px;
}

/* Third Level */
ul ul ul{
  margin-left:20px;
}

/* and so on... */

You can indent the lis and (if applicable) the as (or whatever content elements you have) as well , each with differing effects. You could also use padding-left instead of margin-left, again depending on the effect you want.

Update

By default, many browsers use padding-left to set the initial indentation. If you want to get rid of that, set padding-left: 0px;

Still, both margin-left and padding-left settings impact the indentation of lists in different ways. Specifically: margin-left impacts the indentation on the outside of the element's border, whereas padding-left affects the spacing on the inside of the element's border. (Learn more about the CSS box model here)

Setting padding-left: 0; leaves the li's bullet icons hanging over the edge of the element's border (at least in Chrome), which may or may not be what you want.

Extending on what Martin said, recording the install output and a little bash scripting does the trick quite nicely. Here's what I do...

for i in $(less install.record);
sudo rm $i;
done;

And presto. Uninstalled.

I was having similar problem recently with version 2.6.6.

@JsonInclude(JsonInclude.Include.NON_NULL)

Using above annotation either on filed or class level was not working as expected. The POJO was mutable where I was applying the annotation. When I changed the behaviour of the POJO to be immutable the annotation worked its magic.

I am not sure if its down to new version or previous versions of this lib had similar behaviour but for 2.6.6 certainly you need to have Immutable POJO for the annotation to work.

objectMapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);

Above option mentioned in various answers of setting serialisation inclusion in ObjectMapper directly at global level works as well but, I prefer controlling it at class or filed level.

So if you wanted all the null fields to be ignored while JSON serialisation then use the annotation at class level but if you want only few fields to ignored in a class then use it over those specific fields. This way its more readable & easy for maintenance if you wanted to change behaviour for specific response.

You can't search a text field without converting it from text to varchar.

declare @table table (a text)
insert into @table values ('a')
insert into @table values ('a')
insert into @table values ('b')
insert into @table values ('c')
insert into @table values ('d')


select *
from @table
where a ='a'

This give an error:

The data types text and varchar are incompatible in the equal to operator.

Wheras this does not:

declare @table table (a varchar(max))

Interestingly, LIKE still works, i.e.

where a like '%a%'

You will get the error on REFRESH_FAST, if you do not create materialized view logs for the master table(s) the query is referring to. If anyone is not familiar with materialized views or using it for the first time, the better way is to use oracle sqldeveloper and graphically put in the options, and the errors also provide much better sense.

you should browse to where java installed, then go to bin directory which contains the java.exe file.

example - C:\Program Files\Java\jdk1.6.0_03\bin\java.exe

but you should run your SQL Developer as Administrator

Try:

String text= br.readLine();
while (text != null) 
{
  System.out.println(text);
  text=br.readLine();
}
in.close();

You should enable the unicode strings feature, and this is the default if you use v5.14;

You should not really use unicode identifiers esp. for foreign code via utf8 as they are insecure in perl5, only cperl got that right. See e.g. http://perl11.org/blog/unicode-identifiers.html

Regarding utf8 for your filehandles/streams: You need decide by yourself the encoding of your external data. A library cannot know that, and since not even libc supports utf8, proper utf8 data is rare. There's more wtf8, the windows aberration of utf8 around.

BTW: Moose is not really "Modern Perl", they just hijacked the name. Moose is perfect Larry Wall-style postmodern perl mixed with Bjarne Stroustrup-style everything goes, with an eclectic aberration of proper perl6 syntax, e.g. using strings for variable names, horrible fields syntax, and a very immature naive implementation which is 10x slower than a proper implementation. cperl and perl6 are the true modern perls, where form follows function, and the implementation is reduced and optimized.

Weak entity exists to solve the multi-valued attributes problem.

There are two types of multi-valued attributes. One is the simply many values for an objects such as a "hobby" as an attribute for a student. The student can have many different hobbies. If we leave the hobbies in the student entity set, "hobby" would not be unique any more. We create a separate entity set as hobby. Then we link the hobby and the student as we need. The hobby entity set is now an associative entity set. As to whether it is weak or not, we need to check whether each entity has enough unique identifiers to identify it. In many opinion, a hobby name can be enough to identify it.

The other type of multi-valued attribute problem does need a weak entity to fix it. Let's say an item entity set in a grocery inventory system. Is the item a category item or the actually item? It is an important question, because a customer can buy the same item at one time and at a certain amount, but he can also buy the same item at a different time with a different amount. Can you see it the same item but of different objects. The item now is a multi-valued attribute. We solve it by first separate the category item with the actual item. The two are now different entity sets. Category item has descriptive attributes of the item, just like the item you usually think of. Actual item can not have descriptive attributes any more because we can not have redundant problem. Actual item can only have date time and amount of the item. You can link them as you need. Now, let's talk about whether one is a weak entity of the other. The descriptive attributes are more than enough to identify each entity in the category item entity set. The actual item only has date time and amount. Even if we pull out all the attributes in a record, we still cannot identify the entity. Think about it is just time and amount. The actual item entity set is a weak entity set. We identify each entity in the set with the help of duplicate prime key from the category item entity set.

This question actually is not JSP related, it is HTTP related. you can just do:

window.location = window.location;

First, I want to explain an assumption that I make for this answer. It is not always true, but quite often:

Interfaces are adjectives; classes are nouns.

(Actually, there are interfaces that are nouns as well, but I want to generalize here.)

So, e.g. an interface may be something such as IDisposable, IEnumerable or IPrintable. A class is an actual implementation of one or more of these interfaces: List or Map may both be implementations of IEnumerable.

To get the point: Often your classes depend on each other. E.g. you could have a Database class which accesses your database (hah, surprise! ;-)), but you also want this class to do logging about accessing the database. Suppose you have another class Logger, then Database has a dependency to Logger.

So far, so good.

You can model this dependency inside your Database class with the following line:

var logger = new Logger();

and everything is fine. It is fine up to the day when you realize that you need a bunch of loggers: Sometimes you want to log to the console, sometimes to the file system, sometimes using TCP/IP and a remote logging server, and so on ...

And of course you do NOT want to change all your code (meanwhile you have gazillions of it) and replace all lines

var logger = new Logger();

by:

var logger = new TcpLogger();

First, this is no fun. Second, this is error-prone. Third, this is stupid, repetitive work for a trained monkey. So what do you do?

Obviously it's a quite good idea to introduce an interface ICanLog (or similar) that is implemented by all the various loggers. So step 1 in your code is that you do:

ICanLog logger = new Logger();

Now the type inference doesn't change type any more, you always have one single interface to develop against. The next step is that you do not want to have new Logger() over and over again. So you put the reliability to create new instances to a single, central factory class, and you get code such as:

ICanLog logger = LoggerFactory.Create();

The factory itself decides what kind of logger to create. Your code doesn't care any longer, and if you want to change the type of logger being used, you change it once: Inside the factory.

Now, of course, you can generalize this factory, and make it work for any type:

ICanLog logger = TypeFactory.Create<ICanLog>();

Somewhere this TypeFactory needs configuration data which actual class to instantiate when a specific interface type is requested, so you need a mapping. Of course you can do this mapping inside your code, but then a type change means recompiling. But you could also put this mapping inside an XML file, e.g.. This allows you to change the actually used class even after compile time (!), that means dynamically, without recompiling!

To give you a useful example for this: Think of a software that does not log normally, but when your customer calls and asks for help because he has a problem, all you send to him is an updated XML config file, and now he has logging enabled, and your support can use the log files to help your customer.

And now, when you replace names a little bit, you end up with a simple implementation of a Service Locator, which is one of two patterns for Inversion of Control (since you invert control over who decides what exact class to instantiate).

All in all this reduces dependencies in your code, but now all your code has a dependency to the central, single service locator.

Dependency injection is now the next step in this line: Just get rid of this single dependency to the service locator: Instead of various classes asking the service locator for an implementation for a specific interface, you - once again - revert control over who instantiates what.

With dependency injection, your Database class now has a constructor that requires a parameter of type ICanLog:

public Database(ICanLog logger) { ... }

Now your database always has a logger to use, but it does not know any more where this logger comes from.

And this is where a DI framework comes into play: You configure your mappings once again, and then ask your DI framework to instantiate your application for you. As the Application class requires an ICanPersistData implementation, an instance of Database is injected - but for that it must first create an instance of the kind of logger which is configured for ICanLog. And so on ...

So, to cut a long story short: Dependency injection is one of two ways of how to remove dependencies in your code. It is very useful for configuration changes after compile-time, and it is a great thing for unit testing (as it makes it very easy to inject stubs and / or mocks).

In practice, there are things you can not do without a service locator (e.g., if you do not know in advance how many instances you do need of a specific interface: A DI framework always injects only one instance per parameter, but you can call a service locator inside a loop, of course), hence most often each DI framework also provides a service locator.

But basically, that's it.

P.S.: What I described here is a technique called constructor injection, there is also property injection where not constructor parameters, but properties are being used for defining and resolving dependencies. Think of property injection as an optional dependency, and of constructor injection as mandatory dependencies. But discussion on this is beyond the scope of this question.

The deepcopy option is the only method that works for me:

from copy import deepcopy

a = [   [ list(range(1, 3)) for i in range(3) ]   ]
b = deepcopy(a)
b[0][1]=[3]
print('Deep:')
print(a)
print(b)
print('-----------------------------')
a = [   [ list(range(1, 3)) for i in range(3) ]   ]
b = a*1
b[0][1]=[3]
print('*1:')
print(a)
print(b)
print('-----------------------------')
a = [   [ list(range(1, 3)) for i in range(3) ] ]
b = a[:]
b[0][1]=[3]
print('Vector copy:')
print(a)
print(b)
print('-----------------------------')
a = [   [ list(range(1, 3)) for i in range(3) ]  ]
b = list(a)
b[0][1]=[3]
print('List copy:')
print(a)
print(b)
print('-----------------------------')
a = [   [ list(range(1, 3)) for i in range(3) ]  ]
b = a.copy()
b[0][1]=[3]
print('.copy():')
print(a)
print(b)
print('-----------------------------')
a = [   [ list(range(1, 3)) for i in range(3) ]  ]
b = a
b[0][1]=[3]
print('Shallow:')
print(a)
print(b)
print('-----------------------------')

leads to output of:

Deep:
[[[1, 2], [1, 2], [1, 2]]]
[[[1, 2], [3], [1, 2]]]
-----------------------------
*1:
[[[1, 2], [3], [1, 2]]]
[[[1, 2], [3], [1, 2]]]
-----------------------------
Vector copy:
[[[1, 2], [3], [1, 2]]]
[[[1, 2], [3], [1, 2]]]
-----------------------------
List copy:
[[[1, 2], [3], [1, 2]]]
[[[1, 2], [3], [1, 2]]]
-----------------------------
.copy():
[[[1, 2], [3], [1, 2]]]
[[[1, 2], [3], [1, 2]]]
-----------------------------
Shallow:

[[[1, 2], [3], [1, 2]]]
-----------------------------

You can use VLOOKUP.

Assuming those are in columns A and B in Sheet1 and Sheet2 each, 22350 is in cell A2 of Sheet1, you can use:

=VLOOKUP(A2, Sheet2!A:B, 2, 0)

This will return you #N/A if there are no matches. Drag/Fill/Copy&Paste the formula to the bottom of your table and that should do it.

I had the same Error, because of JUNIT version, I had 3 3.8.1 and I have changed to 4.8.1.

so the solution is

you have to go to POM, and make sure that you dependency looks like this

 <dependency>
  <groupId>junit</groupId>
  <artifactId>junit</artifactId>
  <version>4.8.1</version>
  <scope>test</scope>
</dependency>

You can use.`

        },
        function(err, result) {
            console.log(result);
            console.log(err);
        })  `

I would use the shebang #!/usr/bin/python (first line of code) with the serial number of Python at the end ;)

Then run the Python file as a script, e.g., ./main.py from the command line, rather than python main.py.

It is the same when you want to run Python from a Linux command line.

You can do like this:

rename %CURR_DIR%\ftp\mywish1.txt text.txt
for /f %%a in (%CURR_DIR%\ftp\text.txt) do (
if "%%a" EQU "ex3" ( 
echo ex5 >> %CURR_DIR%\ftp\mywish1.txt
) else (
echo %%a >> %CURR_DIR%\ftp\mywish1.txt
)
)
del %CURR_DIR%\ftp\text.txt

If you want to leave the original array intact,

you need a second array to contain the uniqe elements of the first-

Most browsers have Array.prototype.filter:

var unique= array1.filter(function(itm, i){
    return array1.indexOf(itm)== i; 
    // returns true for only the first instance of itm
});


//if you need a 'shim':
Array.prototype.filter= Array.prototype.filter || function(fun, scope){
    var T= this, A= [], i= 0, itm, L= T.length;
    if(typeof fun== 'function'){
        while(i<L){
            if(i in T){
                itm= T[i];
                if(fun.call(scope, itm, i, T)) A[A.length]= itm;
            }
            ++i;
        }
    }
    return A;
}
 Array.prototype.indexOf= Array.prototype.indexOf || function(what, i){
        if(!i || typeof i!= 'number') i= 0;
        var L= this.length;
        while(i<L){
            if(this[i]=== what) return i;
            ++i;
        }
        return -1;
    }

If you are looking for contains & not equals then i would propose below solution. Only drawback is if your searchItem in below solution is "DE" then also it would match

    List<String> list = new ArrayList<>();
    public static final String[] LIST_OF_ELEMENTS = { "ABC", "DEF","GHI" };
    String searchItem= "def";

     if(String.join(",", LIST_OF_ELEMENTS).contains(searchItem.toUpperCase())) {
            System.out.println("found element");
            break;
    }

I came across this question when I was trying to find multiple filenames that I could not combine into a regular expression as described in @Chris J's answer, here is what worked for me

find . -name one.pdf -o -name two.txt -o -name anotherone.jpg

-o or -or is logical OR. See Finding Files on Gnu.org for more information.

I was running this on CygWin.

Yes, you'll see it everywhere. It's often that = this;.

See how self is used inside functions called by events? Those would have their own context, so self is used to hold the this that came into Note().

The reason self is still available to the functions, even though they can only execute after the Note() function has finished executing, is that inner functions get the context of the outer function due to closure.

An extremely simple way to auto-compile upon save is to type the following into the terminal:

tsc main --watch

where main.ts is your file name.

Note, this will only run as long as this terminal is open, but it's a very simple solution that can be run while you're editing a program.

In my case need to get the last line of a text file that is inserted by other application, as soon as insertion is done. Here is my solution. When the first event is raised, i disable the watcher from raising others, then i call the timer TimeElapsedEvent because when my handle function OnChanged is called i need the size of the text file, but the size at that time is not the actual size, it is the size of the file imediatelly before the insertion. So i wait for a while to proceed with the right file size.

private FileSystemWatcher watcher = new FileSystemWatcher();
...
watcher.Path = "E:\\data";
watcher.NotifyFilter = NotifyFilters.LastWrite ;
watcher.Filter = "data.txt";
watcher.Changed += new FileSystemEventHandler(OnChanged);
watcher.EnableRaisingEvents = true;

...

private void OnChanged(object source, FileSystemEventArgs e)
   {
    System.Timers.Timer t = new System.Timers.Timer();
    try
    {
        watcher.Changed -= new FileSystemEventHandler(OnChanged);
        watcher.EnableRaisingEvents = false;

        t.Interval = 500;
        t.Elapsed += (sender, args) => t_Elapsed(sender, e);
        t.Start();
    }
    catch(Exception ex) {
        ;
    }
}

private void t_Elapsed(object sender, FileSystemEventArgs e) 
   {
    ((System.Timers.Timer)sender).Stop();
       //.. Do you stuff HERE ..
     watcher.Changed += new FileSystemEventHandler(OnChanged);
     watcher.EnableRaisingEvents = true;
}

Use Jenkins.

Jenkins is the recent fork by the core developers of Hudson. To understand why, you need to know the history of the project. It was originally open source and supported by Sun. Like much of what Sun did, it was fairly open, but there was a bit of benign neglect. The source, trackers, website, etc. were hosted by Sun on their relatively closed java.net platform.

Then Oracle bought Sun. For various reasons Oracle has not been shy about leveraging what it perceives as its assets. Those include some control over the logistic platform of Hudson, and particularly control over the Hudson name. Many users and contributors weren't comfortable with that and decided to leave.

So it comes down to what Hudson vs Jenkins offers. Both Oracle's Hudson and Jenkins have the code. Hudson has Oracle and Sonatype's corporate support and the brand. Jenkins has most of the core developers, the community, and (so far) much more actual work.

Read that post I linked up top, then read the rest of these in chronological order. For balance you can read the Hudson/Oracle take on it. It's pretty clear to me who is playing defensive and who has real intentions for the project.

There are already multiple answers and formatting types for SQL server 2008. But this method somewhat ambiguous and it would be difficult for you to remember the number with respect to Specific Date Format. That's why in next versions of SQL server there is better option.

If you are using SQL Server 2012 or above versions, you should use Format() function

FORMAT ( value, format [, culture ] )

With culture option, you can specify date as per your viewers.

DECLARE @d DATETIME = '10/01/2011';
SELECT FORMAT ( @d, 'd', 'en-US' ) AS 'US English Result'
      ,FORMAT ( @d, 'd', 'en-gb' ) AS 'Great Britain English Result'
      ,FORMAT ( @d, 'd', 'de-de' ) AS 'German Result'

SELECT FORMAT ( @d, 'D', 'en-US' ) AS 'US English Result'
      ,FORMAT ( @d, 'D', 'en-gb' ) AS 'Great Britain English Result'
      ,FORMAT ( @d, 'D', 'de-de' ) AS 'German Result'
      ,FORMAT ( @d, 'D', 'zh-cn' ) AS 'Chinese (Simplified PRC) Result';

To interpret a byte sequence as a text, you have to know the corresponding character encoding:

unicode_text = bytestring.decode(character_encoding)

Example:

>>> b'\xc2\xb5'.decode('utf-8')
'µ'

ls command may produce output that can't be interpreted as text. File names on Unix may be any sequence of bytes except slash b'/' and zero b'\0':

>>> open(bytes(range(0x100)).translate(None, b'\0/'), 'w').close()

Trying to decode such byte soup using utf-8 encoding raises UnicodeDecodeError.

It can be worse. The decoding may fail silently and produce mojibake if you use a wrong incompatible encoding:

>>> '—'.encode('utf-8').decode('cp1252')
'—'

The data is corrupted but your program remains unaware that a failure has occurred.

In general, what character encoding to use is not embedded in the byte sequence itself. You have to communicate this info out-of-band. Some outcomes are more likely than others and therefore chardet module exists that can guess the character encoding. A single Python script may use multiple character encodings in different places.

ls output can be converted to a Python string using os.fsdecode() function that succeeds even for undecodable filenames (it uses sys.getfilesystemencoding() and surrogateescape error handler on Unix):

import os
import subprocess

output = os.fsdecode(subprocess.check_output('ls'))

To get the original bytes, you could use os.fsencode().

If you pass universal_newlines=True parameter then subprocess uses locale.getpreferredencoding(False) to decode bytes e.g., it can be cp1252 on Windows.

To decode the byte stream on-the-fly, io.TextIOWrapper() could be used: example.

Different commands may use different character encodings for their output e.g., dir internal command (cmd) may use cp437. To decode its output, you could pass the encoding explicitly (Python 3.6+):

output = subprocess.check_output('dir', shell=True, encoding='cp437')

The filenames may differ from os.listdir() (which uses Windows Unicode API) e.g., '\xb6' can be substituted with '\x14'—Python's cp437 codec maps b'\x14' to control character U+0014 instead of U+00B6 (¶). To support filenames with arbitrary Unicode characters, see Decode PowerShell output possibly containing non-ASCII Unicode characters into a Python string

Overview

Why do we need the copy-and-swap idiom?

Any class that manages a resource (a wrapper, like a smart pointer) needs to implement The Big Three. While the goals and implementation of the copy-constructor and destructor are straightforward, the copy-assignment operator is arguably the most nuanced and difficult. How should it be done? What pitfalls need to be avoided?

The copy-and-swap idiom is the solution, and elegantly assists the assignment operator in achieving two things: avoiding code duplication, and providing a strong exception guarantee.

How does it work?

Conceptually, it works by using the copy-constructor's functionality to create a local copy of the data, then takes the copied data with a swap function, swapping the old data with the new data. The temporary copy then destructs, taking the old data with it. We are left with a copy of the new data.

In order to use the copy-and-swap idiom, we need three things: a working copy-constructor, a working destructor (both are the basis of any wrapper, so should be complete anyway), and a swap function.

A swap function is a non-throwing function that swaps two objects of a class, member for member. We might be tempted to use std::swap instead of providing our own, but this would be impossible; std::swap uses the copy-constructor and copy-assignment operator within its implementation, and we'd ultimately be trying to define the assignment operator in terms of itself!

(Not only that, but unqualified calls to swap will use our custom swap operator, skipping over the unnecessary construction and destruction of our class that std::swap would entail.)

An in-depth explanation

The goal

Let's consider a concrete case. We want to manage, in an otherwise useless class, a dynamic array. We start with a working constructor, copy-constructor, and destructor:

#include <algorithm> // std::copy
#include <cstddef> // std::size_t

class dumb_array
{
public:
    // (default) constructor
    dumb_array(std::size_t size = 0)
        : mSize(size),
          mArray(mSize ? new int[mSize]() : nullptr)
    {
    }

    // copy-constructor
    dumb_array(const dumb_array& other)
        : mSize(other.mSize),
          mArray(mSize ? new int[mSize] : nullptr),
    {
        // note that this is non-throwing, because of the data
        // types being used; more attention to detail with regards
        // to exceptions must be given in a more general case, however
        std::copy(other.mArray, other.mArray + mSize, mArray);
    }

    // destructor
    ~dumb_array()
    {
        delete [] mArray;
    }

private:
    std::size_t mSize;
    int* mArray;
};

This class almost manages the array successfully, but it needs operator= to work correctly.

A failed solution

Here's how a naive implementation might look:

// the hard part
dumb_array& operator=(const dumb_array& other)
{
    if (this != &other) // (1)
    {
        // get rid of the old data...
        delete [] mArray; // (2)
        mArray = nullptr; // (2) *(see footnote for rationale)

        // ...and put in the new
        mSize = other.mSize; // (3)
        mArray = mSize ? new int[mSize] : nullptr; // (3)
        std::copy(other.mArray, other.mArray + mSize, mArray); // (3)
    }

    return *this;
}

And we say we're finished; this now manages an array, without leaks. However, it suffers from three problems, marked sequentially in the code as (n).

1. The first is the self-assignment test. This check serves two purposes: it's an easy way to prevent us from running needless code on self-assignment, and it protects us from subtle bugs (such as deleting the array only to try and copy it). But in all other cases it merely serves to slow the program down, and act as noise in the code; self-assignment rarely occurs, so most of the time this check is a waste. It would be better if the operator could work properly without it.

2. The second is that it only provides a basic exception guarantee. If new int[mSize] fails, *this will have been modified. (Namely, the size is wrong and the data is gone!) For a strong exception guarantee, it would need to be something akin to:

   dumb_array& operator=(const dumb_array& other)
   {
       if (this != &other) // (1)
       {
           // get the new data ready before we replace the old
           std::size_t newSize = other.mSize;
           int* newArray = newSize ? new int[newSize]() : nullptr; // (3)
           std::copy(other.mArray, other.mArray + newSize, newArray); // (3)
   
           // replace the old data (all are non-throwing)
           delete [] mArray;
           mSize = newSize;
           mArray = newArray;
       }
   
       return *this;
   }
   

3. The code has expanded! Which leads us to the third problem: code duplication. Our assignment operator effectively duplicates all the code we've already written elsewhere, and that's a terrible thing.

In our case, the core of it is only two lines (the allocation and the copy), but with more complex resources this code bloat can be quite a hassle. We should strive to never repeat ourselves.

(One might wonder: if this much code is needed to manage one resource correctly, what if my class manages more than one? While this may seem to be a valid concern, and indeed it requires non-trivial try/catch clauses, this is a non-issue. That's because a class should manage one resource only!)

A successful solution

As mentioned, the copy-and-swap idiom will fix all these issues. But right now, we have all the requirements except one: a swap function. While The Rule of Three successfully entails the existence of our copy-constructor, assignment operator, and destructor, it should really be called "The Big Three and A Half": any time your class manages a resource it also makes sense to provide a swap function.

We need to add swap functionality to our class, and we do that as follows†:

class dumb_array
{
public:
    // ...

    friend void swap(dumb_array& first, dumb_array& second) // nothrow
    {
        // enable ADL (not necessary in our case, but good practice)
        using std::swap;

        // by swapping the members of two objects,
        // the two objects are effectively swapped
        swap(first.mSize, second.mSize);
        swap(first.mArray, second.mArray);
    }

    // ...
};

(Here is the explanation why public friend swap.) Now not only can we swap our dumb_array's, but swaps in general can be more efficient; it merely swaps pointers and sizes, rather than allocating and copying entire arrays. Aside from this bonus in functionality and efficiency, we are now ready to implement the copy-and-swap idiom.

Without further ado, our assignment operator is:

dumb_array& operator=(dumb_array other) // (1)
{
    swap(*this, other); // (2)

    return *this;
}

And that's it! With one fell swoop, all three problems are elegantly tackled at once.

Why does it work?

We first notice an important choice: the parameter argument is taken by-value. While one could just as easily do the following (and indeed, many naive implementations of the idiom do):

dumb_array& operator=(const dumb_array& other)
{
    dumb_array temp(other);
    swap(*this, temp);

    return *this;
}

We lose an important optimization opportunity. Not only that, but this choice is critical in C++11, which is discussed later. (On a general note, a remarkably useful guideline is as follows: if you're going to make a copy of something in a function, let the compiler do it in the parameter list.‡)

Either way, this method of obtaining our resource is the key to eliminating code duplication: we get to use the code from the copy-constructor to make the copy, and never need to repeat any bit of it. Now that the copy is made, we are ready to swap.

Observe that upon entering the function that all the new data is already allocated, copied, and ready to be used. This is what gives us a strong exception guarantee for free: we won't even enter the function if construction of the copy fails, and it's therefore not possible to alter the state of *this. (What we did manually before for a strong exception guarantee, the compiler is doing for us now; how kind.)

At this point we are home-free, because swap is non-throwing. We swap our current data with the copied data, safely altering our state, and the old data gets put into the temporary. The old data is then released when the function returns. (Where upon the parameter's scope ends and its destructor is called.)

Because the idiom repeats no code, we cannot introduce bugs within the operator. Note that this means we are rid of the need for a self-assignment check, allowing a single uniform implementation of operator=. (Additionally, we no longer have a performance penalty on non-self-assignments.)

And that is the copy-and-swap idiom.

What about C++11?

The next version of C++, C++11, makes one very important change to how we manage resources: the Rule of Three is now The Rule of Four (and a half). Why? Because not only do we need to be able to copy-construct our resource, we need to move-construct it as well.

Luckily for us, this is easy:

class dumb_array
{
public:
    // ...

    // move constructor
    dumb_array(dumb_array&& other) noexcept ††
        : dumb_array() // initialize via default constructor, C++11 only
    {
        swap(*this, other);
    }

    // ...
};

What's going on here? Recall the goal of move-construction: to take the resources from another instance of the class, leaving it in a state guaranteed to be assignable and destructible.

So what we've done is simple: initialize via the default constructor (a C++11 feature), then swap with other; we know a default constructed instance of our class can safely be assigned and destructed, so we know other will be able to do the same, after swapping.

(Note that some compilers do not support constructor delegation; in this case, we have to manually default construct the class. This is an unfortunate but luckily trivial task.)

Why does that work?

That is the only change we need to make to our class, so why does it work? Remember the ever-important decision we made to make the parameter a value and not a reference:

dumb_array& operator=(dumb_array other); // (1)

Now, if other is being initialized with an rvalue, it will be move-constructed. Perfect. In the same way C++03 let us re-use our copy-constructor functionality by taking the argument by-value, C++11 will automatically pick the move-constructor when appropriate as well. (And, of course, as mentioned in previously linked article, the copying/moving of the value may simply be elided altogether.)

And so concludes the copy-and-swap idiom.

Footnotes

*Why do we set mArray to null? Because if any further code in the operator throws, the destructor of dumb_array might be called; and if that happens without setting it to null, we attempt to delete memory that's already been deleted! We avoid this by setting it to null, as deleting null is a no-operation.

†There are other claims that we should specialize std::swap for our type, provide an in-class swap along-side a free-function swap, etc. But this is all unnecessary: any proper use of swap will be through an unqualified call, and our function will be found through ADL. One function will do.

‡The reason is simple: once you have the resource to yourself, you may swap and/or move it (C++11) anywhere it needs to be. And by making the copy in the parameter list, you maximize optimization.

††The move constructor should generally be noexcept, otherwise some code (e.g. std::vector resizing logic) will use the copy constructor even when a move would make sense. Of course, only mark it noexcept if the code inside doesn't throw exceptions.

ASP.NET Version:4.0.30319.18408 belongs to .Net4.5 and System.Web.Http Version=4.0.0.0 is compatible for .NET4.0. So the versions that you have are not compatible. You should update you System.Web.Http to version 5.0.0.0, which is compatible with .Net4.5

Create a HttpRequestMessage, set the Method to GET, set your headers and then use SendAsync instead of GetAsync.

    Method = HttpMethod.Get,
};
request.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("text/plain"));

The explanation from Scott Meyers in Effective C++ might help understand when to use them:

Public inheritance should model "is-a relationship," whereas private inheritance should be used for "is-implemented-in-terms-of" - so you don't have to adhere to the interface of the superclass, you're just reusing the implementation.

Extract numbers from any string at beginning position.

x <- gregexpr("^[0-9]+", years)  # Numbers with any number of digits
x2 <- as.numeric(unlist(regmatches(years, x)))

Extract numbers from any string INDEPENDENT of position.

x <- gregexpr("[0-9]+", years)  # Numbers with any number of digits
x2 <- as.numeric(unlist(regmatches(years, x)))

If you want to trim specified number of spaces from left and right, you could do this:

def remove_outer_spaces(text, num_of_leading, num_of_trailing):
    text = list(text)
    for i in range(num_of_leading):
        if text[i] == " ":
            text[i] = ""
        else:
            break

    for i in range(1, num_of_trailing+1):
        if text[-i] == " ":
            text[-i] = ""
        else:
            break
    return ''.join(text)

txt1 = "   MY name is     "
print(remove_outer_spaces(txt1, 1, 1))  # result is: "  MY name is    "
print(remove_outer_spaces(txt1, 2, 3))  # result is: " MY name is  "
print(remove_outer_spaces(txt1, 6, 8))  # result is: "MY name is"

The fastest way to do file I/O from C# is to use the Windows ReadFile and WriteFile functions. I have written a C# class that encapsulates this capability as well as a benchmarking program that looks at differnet I/O methods, including BinaryReader and BinaryWriter. See my blog post at:

http://designingefficientsoftware.wordpress.com/2011/03/03/efficient-file-io-from-csharp/

The problem with all these answers is that they do not take virtual directories into account.

Consider:

Site named "tempuri.com/" rooted at c:\domains\site
virtual directory "~/files" at c:\data\files
virtual directory "~/files/vip" at c:\data\VIPcust\files

So:

Server.MapPath("~/files/vip/readme.txt") 
  = "c:\data\VIPcust\files\readme.txt"

But there is no way to do this:

MagicResolve("c:\data\VIPcust\files\readme.txt") 
   = "http://tempuri.com/files/vip/readme.txt"

because there is no way to get a complete list of virtual directories.

You cannot use a select statement that assigns values to variables to also return data to the user The below code will work fine, because i have declared 1 local variable and that variable is used in select statement.

 Begin
    DECLARE @name nvarchar(max)
    select @name=PolicyHolderName from Table
    select @name
    END

The below code will throw error "A SELECT statement that assigns a value to a variable must not be combined with data-retrieval operations" Because we are retriving data(PolicyHolderAddress) from table, but error says data-retrieval operation is not allowed when you use some local variable as part of select statement.

 Begin
    DECLARE @name nvarchar(max)
    select 
       @name = PolicyHolderName,
       PolicyHolderAddress 
    from Table
 END

The the above code can be corrected like below,

Begin
    DECLARE @name nvarchar(max)
    DECLARE @address varchar(100)
    select 
       @name = PolicyHolderName,
       @address = PolicyHolderAddress 
    from Table
END

So either remove the data-retrieval operation or add extra local variable. This will resolve the error.

Compatibility with older browsers can be a drag, so be adviced.

If that is not a problem then go ahead. Run the snippet. Go to full page view and resize. Center will resize itself with no changes to the left or right divs.

Change left and right values to meet your requirement.

Thank you.

Hope this helps.

I found on the sqlite documentation (https://www.sqlite.org/lang_datefunc.html) this text:

Compute the date and time given a unix timestamp 1092941466, and compensate for your local timezone.

SELECT datetime(1092941466, 'unixepoch', 'localtime');

That didn't look like it fit my needs, so I tried changing the "datetime" function around a bit, and wound up with this:

select datetime(timestamp, 'localtime')

That seems to work - is that the correct way to convert for your timezone, or is there a better way to do this?

1. Open Command Prompt
2. then go your project folder thru Command prompt
3. Type gradlew build and run

public DataSet GetDataSet(string ConnectionString, string SQL)
{
    SqlConnection conn = new SqlConnection(ConnectionString);
    SqlDataAdapter da = new SqlDataAdapter();
    SqlCommand cmd = conn.CreateCommand();
    cmd.CommandText = SQL;
    da.SelectCommand = cmd;
    DataSet ds = new DataSet();

    ///conn.Open();
    da.Fill(ds);
    ///conn.Close();

    return ds;
}

These are identical for printf but different for scanf. For printf, both %d and %i designate a signed decimal integer. For scanf, %d and %i also means a signed integer but %i inteprets the input as a hexadecimal number if preceded by 0x and octal if preceded by 0 and otherwise interprets the input as decimal.

Here is what worked for me.

1. Set the app pool identity to an account that can be assigned permissions to a folder.
2. Ensure the source directory and all related files have been granted read rights to the files to the account assigned to the app pool identity property
3. In IIS, at the server root node, set anonymous user to inherit from app pool identity. (This was the part I struggled with)

To set the server anonymous to inherit from the app pool identity do the following..

• Open IIS Manager (inetmgr)
• In the left-hand pane select the root node (server host name)
• In the middle pane open the 'Authentication' applet
• Highlight 'Anonymous Authentication'
• In the right-hand pane select 'Edit...' (a dialog box should open)
• select 'Application pool identity'

Check tis article on Partial Key Verification which covers the following requirements:

• License keys must be easy enough to type in.

• We must be able to blacklist (revoke) a license key in the case of chargebacks or purchases with stolen credit cards.

• No “phoning home” to test keys. Although this practice is becoming more and more prevalent, I still do not appreciate it as a user, so will not ask my users to put up with it.

• It should not be possible for a cracker to disassemble our released application and produce a working “keygen” from it. This means that our application will not fully test a key for verification. Only some of the key is to be tested. Further, each release of the application should test a different portion of the key, so that a phony key based on an earlier release will not work on a later release of our software.

• Important: it should not be possible for a legitimate user to accidentally type in an invalid key that will appear to work but fail on a future version due to a typographical error.

It would be too tedious to alter function usages in all html pages to return false.

So here is a tested solution that patches only the function itself:

function callmymethod(myVal) {
    // doing custom things with myVal

    // cancel default event action
    var event = window.event || callmymethod.caller.arguments[0];
    event.preventDefault ? event.preventDefault() : (event.returnValue = false);

    return false;
}    

This correctly prevents IE6, IE11 and latest Chrome from visiting href="#" after onclick event handler completes.

Credits:

• How do you find out the caller function in JavaScript?
• event.preventDefault() function not working in IE

If I recall correctly, gcc determines the filetype from the suffix. So, make it foo.cc and it should work.

And, to answer your other question, that is the difference between "gcc" and "g++". gcc is a frontend that chooses the correct compiler.

You can build DFA using simple modular arithmetics. We can interpret w which is a string of k-ary numbers using a following rule

V[0] = 0
V[i] = (S[i-1] * k) + to_number(str[i])

V[|w|] is a number that w is representing. If modify this rule to find w mod N, the rule becomes this.

V[0] = 0
V[i] = ((S[i-1] * k) + to_number(str[i])) mod N

and each V[i] is one of a number from 0 to N-1, which corresponds to each state in DFA. We can use this as the state transition.

See an example.

k = 2, N = 5

| V | (V*2 + 0) mod 5     | (V*2 + 1) mod 5     |
+---+---------------------+---------------------+
| 0 | (0*2 + 0) mod 5 = 0 | (0*2 + 1) mod 5 = 1 |
| 1 | (1*2 + 0) mod 5 = 2 | (1*2 + 1) mod 5 = 3 |
| 2 | (2*2 + 0) mod 5 = 4 | (2*2 + 1) mod 5 = 0 |
| 3 | (3*2 + 0) mod 5 = 1 | (3*2 + 1) mod 5 = 2 |
| 4 | (4*2 + 0) mod 5 = 3 | (4*2 + 1) mod 5 = 4 |

k = 3, N = 5

| V | 0 | 1 | 2 |
+---+---+---+---+
| 0 | 0 | 1 | 2 |
| 1 | 3 | 4 | 0 |
| 2 | 1 | 2 | 3 |
| 3 | 4 | 0 | 1 |
| 4 | 2 | 3 | 4 |

Now you can see a very simple pattern. You can actually build a DFA transition just write repeating numbers from left to right, from top to bottom, from 0 to N-1.

You have to realize that server-side sessions are an artificial add-on to HTTP. Since HTTP is stateless, the server needs to somehow recognize that a request belongs to a particular user it knows and has a session for. There are 2 ways to do this:

• Cookies. The cleaner and more popular method, but it means that all browser tabs and windows by one user share the session - IMO this is in fact desirable, and I would be very annoyed at a site that made me login for each new tab, since I use tabs very intensively
• URL rewriting. Any URL on the site has a session ID appended to it. This is more work (you have to do something everywhere you have a site-internal link), but makes it possible to have separate sessions in different tabs, though tabs opened through link will still share the session. It also means the user always has to log in when he comes to your site.

What are you trying to do anyway? Why would you want tabs to have separate sessions? Maybe there's a way to achieve your goal without using sessions at all?

Edit: For testing, other solutions can be found (such as running several browser instances on separate VMs). If one user needs to act in different roles at the same time, then the "role" concept should be handled in the app so that one login can have several roles. You'll have to decide whether this, using URL rewriting, or just living with the current situation is more acceptable, because it's simply not possible to handle browser tabs separately with cookie-based sessions.

Came here looking for an answer to the same problem, but I'm using WCF for NET Core. If you're in the same boat, use:

client.ClientCredentials.ServiceCertificate.SslCertificateAuthentication = 
    new X509ServiceCertificateAuthentication()
    {
        CertificateValidationMode = X509CertificateValidationMode.None,
        RevocationMode = X509RevocationMode.NoCheck
    };

They are two different concepts: "void pointer" is a type (void *). "null pointer" is a pointer that has a value of zero (NULL). Example:

void *pointer = NULL;

That's a NULL void pointer.

There are several answers here but none of them satisfied my below requirements:

1. I don't want to wait for command to finish or pollute my terminal with subprocess outputs.

2. I want to run bash script with redirects.

3. I want to support piping within my bash script (for example find ... | tar ...).

The only combination that satiesfies above requirements is:

subprocess.Popen(['./my_script.sh "arg1" > "redirect/path/to"'],
                 stdout=subprocess.PIPE, 
                 stderr=subprocess.PIPE,
                 shell=True)

The patch is here: https://code.ros.org/trac/opencv/attachment/ticket/862/OpenCV-2.2-nov4l1.patch

By adding #ifdef HAVE_CAMV4L around

#include <linux/videodev.h>

in OpenCV-2.2.0/modules/highgui/src/cap_v4l.cpp and removing || defined (HAVE_CAMV4L2) from line 174 allowed me to compile.

Now we have to use android.hardware.camera2 as android.hardware.Camera is deprecated which will only work on API >23 FlashLight

   public class MainActivity extends AppCompatActivity {

     Button button;

     Boolean light=true;

     CameraDevice cameraDevice;

     private CameraManager cameraManager;

     private CameraCharacteristics cameraCharacteristics;

     String cameraId;

     @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        button=(Button)findViewById(R.id.button);
        cameraManager = (CameraManager) 
        getSystemService(Context.CAMERA_SERVICE);
        try {
          cameraId = cameraManager.getCameraIdList()[0];
        } catch (CameraAccessException e) {
            e.printStackTrace();
        }
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if(light){
                    try {

                        cameraManager.setTorchMode(cameraId,true);
                    } catch (CameraAccessException e) {
                        e.printStackTrace();
                    }

                    light=false;}
                    else {

                    try {

                      cameraManager.setTorchMode(cameraId,false);
                    } catch (CameraAccessException e) {
                        e.printStackTrace();
                    }


                    light=true;
                    }


            }
        });
    }

There is a great implementation of NavigationDrawer that follows the Google Material Design Guidelines (and compatible down to API 10) - The MaterialDrawer library (link to GitHub). As of time of writing, May 2017, it's actively supported.

It's available in Maven Central repo. Gradle dependency setup:

compile 'com.mikepenz:materialdrawer:5.9.1'

Maven dependency setup:

<dependency>
    <groupId>com.mikepenz</groupId>
    <artifactId>materialdrawer</artifactId>
    <version>5.9.1</version>
</dependency>

An Exception is an Object like any other in Java. You need to use the new keyword to create a new Exception before you can throw it.

throw new RuntimeException();

Optionally you could also do the following:

RuntimeException e = new RuntimeException();
throw e;

Both code snippets are equivalent.

Link to the tutorials for completeness.

As has been pointed out in a couple of other answers, the preferred method now is NOT to use smartindent, but instead use the following (in your .vimrc):

filetype plugin indent on
" show existing tab with 4 spaces width
set tabstop=4
" when indenting with '>', use 4 spaces width
set shiftwidth=4
" On pressing tab, insert 4 spaces
set expandtab

set smartindent
set tabstop=4
set shiftwidth=4
set expandtab

:help smartindent

:help auto-setting

:set all

:help C-indenting

In the docker containers(centos based images) it is located at

/etc/mysql/my.cnf

Lists both local and remote branches:

$ git branch -ra

Output:

  feature/feature1
  feature/feature2
  hotfix/hotfix1
* master
  remotes/origin/HEAD -> origin/master
  remotes/origin/develop
  remotes/origin/master

Use tiles. It saved my life.

But if you can't, there's the include tag, making it similar to php.

The body tag might not actually do what you need it to, unless you have super simple content. The body tag is used to define the body of a specified element. Take a look at this example:

<jsp:element name="${content.headerName}"   
   xmlns:jsp="http://java.sun.com/JSP/Page">    
   <jsp:attribute name="lang">${content.lang}</jsp:attribute>   
   <jsp:body>${content.body}</jsp:body> 
</jsp:element>

You specify the element name, any attributes that element might have ("lang" in this case), and then the text that goes in it--the body. So if

• content.headerName = h1,
• content.lang = fr, and
• content.body = Heading in French

Then the output would be

<h1 lang="fr">Heading in French</h1>

Well, longs can't hold anything but integers.

One option is to use a float: float('234.89')

The other option is to truncate or round. Converting from a float to a long will truncate for you: long(float('234.89'))

>>> long(float('1.1'))
1L
>>> long(float('1.9'))
1L
>>> long(round(float('1.1')))
1L
>>> long(round(float('1.9')))
2L

@Juri

If you add IntentFilters for your service, you are saying you want to expose your service to other applications, then it may be stopped unexpectedly by other applications.

This works for me (code called from node js repl):

const axios = require("axios");

axios
    .put(
        "http://localhost:4000/api/token", 
        "mytoken", 
        {headers: {"Content-Type": "text/plain"}}
    )
    .then(r => console.log(r.status))
    .catch(e => console.log(e));

Logs: 200

And this is my request handler (I am using restify):

function handleToken(req, res) {
    if(typeof req.body === "string" && req.body.length > 3) {
        res.send(200);
    } else {
        res.send(400);
    }
}

Content-Type header is important here.

Yes, but be careful when using between for dates.

BETWEEN '20090101' AND '20090131'

is really interpreted as 12am, or

BETWEEN '20090101 00:00:00' AND '20090131 00:00:00'

so will miss anything that occurred during the day of Jan 31st. In this case, you will have to use:

myDate >= '20090101 00:00:00' AND myDate < '20090201 00:00:00'  --CORRECT!

or

BETWEEN '20090101 00:00:00' AND '20090131 23:59:59' --WRONG! (see update!)

UPDATE: It is entirely possible to have records created within that last second of the day, with a datetime as late as 20090101 23:59:59.997!!

For this reason, the BETWEEN (firstday) AND (lastday 23:59:59) approach is not recommended.

Use the myDate >= (firstday) AND myDate < (Lastday+1) approach instead.

Good article on this issue here.

You can also do it as a one-liner directly in your crontab:

* * * * * [ `ps -ef|grep -v grep|grep <command>` -eq 0 ] && <command>

First of all you missed ScriptService attribute to add in webservice.

[ScriptService]

After then try following method to call webservice via JSON.

        var webAddr = "http://Domain/VBRService.asmx/callJson";
        var httpWebRequest = (HttpWebRequest)WebRequest.Create(webAddr);
        httpWebRequest.ContentType = "application/json; charset=utf-8";
        httpWebRequest.Method = "POST";            

        using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
        {
            string json = "{\"x\":\"true\"}";

            streamWriter.Write(json);
            streamWriter.Flush();
        }

        var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
        using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
        {
            var result = streamReader.ReadToEnd();
            return result;
        }

I do this is via the github API:

curl -H "Authorization: token %(access_token)s" -sL -o /tmp/repo.tar.gz "http://api.github.com/repos/%(organisation)s/%(repo)s/tarball/%(tag)s" ;\
tar xfz /tmp/repo.tar.gz -C /tmp/repo --strip-components=1 ; \

Zoom and transform scale are not the same thing. They are applied at different times. Zoom is applied before the rendering happens, transform - after. The result of this is if you take a div with width/height = 100% nested inside of another div, with fixed size, if you apply zoom, everything inside your inner zoom will shrink, or grow, but if you apply transform your entire inner div will shrink (even though width/height is set to 100%, they are not going to be 100% after transformation).

If anyone is looking for a ToMultiKeyDictionary() here is an implementation that should work with most of the answers here (based on Herman's):

public static class Extensions_MultiKeyDictionary {

    public static MultiKeyDictionary<K1, K2, V> ToMultiKeyDictionary<S, K1, K2, V>(this IEnumerable<S> items, Func<S, K1> key1, Func<S, K2> key2, Func<S, V> value) {
        var dict = new MultiKeyDictionary<K1, K2, V>(); 
        foreach (S i in items) { 
            dict.Add(key1(i), key2(i), value(i)); 
        } 
        return dict; 
    }

    public static MultiKeyDictionary<K1, K2, K3, V> ToMultiKeyDictionary<S, K1, K2, K3, V>(this IEnumerable<S> items, Func<S, K1> key1, Func<S, K2> key2, Func<S, K3> key3, Func<S, V> value) {
        var dict = new MultiKeyDictionary<K1, K2, K3, V>(); 
        foreach (S i in items) { 
            dict.Add(key1(i), key2(i), key3(i), value(i)); 
        } 
        return dict; 
    }
}

I had the same issue when I was using Godaddy web hosting and solved this by editing my .env file as,

MAIL_DRIVER=smtp
MAIL_HOST=XXXX.XXXX.in
MAIL_PORT=587
MAIL_USERNAME=dexxxxx
MAIL_PASSWORD=XXXXXXXX
MAIL_ENCRYPTION=tls

Where MAIL_HOST is your domain name from Godaddy, MAIL_USERNAME is your user name from Godaddy and MAIL_PASSWORD is your password from Godaddy.

I hope this may help you.

you can do it by two simple point and change in your code

1.In your xml in anim folder of your project, Set the fade in and fade out duration time not equal

2.In you java class before the start of fade out animation, set second imageView visibility Gone then after fade out animation started set second imageView visibility which you want to fade in visible

fadeout.xml

<alpha
    android:duration="4000"
    android:fromAlpha="1.0"
    android:interpolator="@android:anim/accelerate_interpolator"
    android:toAlpha="0.0" />

fadein.xml

<alpha
    android:duration="6000"
    android:fromAlpha="0.0"
    android:interpolator="@android:anim/accelerate_interpolator"
    android:toAlpha="1.0" />

In you java class

Animation animFadeOut = AnimationUtils.loadAnimation(this, R.anim.fade_out);
    ImageView iv = (ImageView) findViewById(R.id.imageView1);
    ImageView iv2 = (ImageView) findViewById(R.id.imageView2);
    iv.setVisibility(View.VISIBLE);
    iv2.setVisibility(View.GONE);
    animFadeOut.reset();
    iv.clearAnimation();
    iv.startAnimation(animFadeOut);

    Animation animFadeIn = AnimationUtils.loadAnimation(this, R.anim.fade_in);
    iv2.setVisibility(View.VISIBLE);
    animFadeIn.reset();
    iv2.clearAnimation();
    iv2.startAnimation(animFadeIn);

label = new JLabel("A label");
label.setFont(new Font("Serif", Font.PLAIN, 14));

Here is my favorite way, which I think is a little less tedious than the "Select for Compare, then Compare With..." steps.

• Open the left side file (not editable)
• F1 Compare Active File With...
• Select the right side file (editable) - You can either select a recent file from the dropdown list, or click any file in the Explorer panel.

This works with any arbitrary files, even ones that are not in the project dir. You can even just create 2 new Untitled files and copy/paste text in there too.

In addition to the answers above the command below will also work. I post it because it makes more sense to me. In each case it is 'using x-value-column: y-value-column'

plot 'ls.dat' using 1:2, 'ls.dat' using 1:3, 'ls.dat' using 1:4 

note that the command above assumes that you have a file named ls.dat with tab separated columns of data where column 1 is x, column 2 is y1, column 3 is y2 and column 4 is y3.

//You may use this example. Might be help you...

$user = User::select("users.*","items.id as itemId","jobs.id as jobId")
        ->join("items","items.user_id","=","users.id")
        ->join("jobs",function($join){
            $join->on("jobs.user_id","=","users.id")
                ->on("jobs.item_id","=","items.id");
        })
        ->get();
print_r($user);

1. Open SQL Server Management Studio
2. Connect to the database engine for which you need the port number

3. Run the below query against the database

   select distinct local_net_address, local_tcp_port from sys.dm_exec_connections where local_net_address is not null

The above query shows the local IP as well as the listening Port number

Arrays can only be passed by reference, actually:

void foo(double (&bar)[10])
{
}

This prevents you from doing things like:

double arr[20];
foo(arr); // won't compile

To be able to pass an arbitrary size array to foo, make it a template and capture the size of the array at compile time:

template<typename T, size_t N>
void foo(T (&bar)[N])
{
    // use N here
}

You should seriously consider using std::vector, or if you have a compiler that supports c++11, std::array.

For those who want to filter from an array of objects using any key:

function filterItems(items, searchVal) {_x000D_
  return items.filter((item) => Object.values(item).includes(searchVal));_x000D_
}_x000D_
let data = [_x000D_
  { "name": "apple", "type": "fruit", "id": 123234 },_x000D_
  { "name": "cat", "type": "animal", "id": 98989 },_x000D_
  { "name": "something", "type": "other", "id": 656565 }]_x000D_
_x000D_
_x000D_
console.log("Filtered by name: ", filterItems(data, "apple"));_x000D_
console.log("Filtered by type: ", filterItems(data, "animal"));_x000D_
console.log("Filtered by id: ", filterItems(data, 656565));

filter from an array of the JSON objects:**

The scp operation is separate from your ssh login. You will need to issue an ssh command similar to the following one assuming jdoe is account with which you log into the remote system and that the remote system is example.com:

scp [email protected]:/somedir/table /home/me/Desktop/.

The scp command issued from the system where /home/me/Desktop resides is followed by the userid for the account on the remote server. You then add a ":" followed by the directory path and file name on the remote server, e.g., /somedir/table. Then add a space and the location to which you want to copy the file. If you want the file to have the same name on the client system, you can indicate that with a period, i.e. "." at the end of the directory path; if you want a different name you could use /home/me/Desktop/newname, instead. If you were using a nonstandard port for SSH connections, you would need to specify that port with a "-P n" (capital P), where "n" is the port number. The standard port is 22 and if you aren't specifying it for the SSH connection then you won't need that.

I had the same issue, but I was running Ubuntu 12.04 through a VM. I am using a Nexus 10. I had added the usb device as a filter for the VM (using virtual box in the virtual machine's settings).

The device I had added was "samsung Nexus 10".

The problem is that once the device is in fastboot mode, it shows up as a different device: "Google, Inc Android 1.0." So doing "lsusb" in the VM showed no device connected, and obviously "fastboot devices" returned nothing until I added the "second" device as a filter for the VM as well.

Hope this helps someone.

You can do all of this with the File System module.

const
  fs = require('fs'),
  dirPath = `path/to/dir`

// Check if directory exists.
fs.access(dirPath, fs.constants.F_OK, (err)=>{
  if (err){
    // Create directory if directory does not exist.
    fs.mkdir(dirPath, {recursive:true}, (err)=>{
      if (err) console.log(`Error creating directory: ${err}`)
      else console.log('Directory created successfully.')
    })
  }
  // Directory now exists.
})

You really don't even need to check if the directory exists. The following code also guarantees that the directory either already exists or is created.

const
  fs = require('fs'),
  dirPath = `path/to/dir`

// Create directory if directory does not exist.
fs.mkdir(dirPath, {recursive:true}, (err)=>{
  if (err) console.log(`Error creating directory: ${err}`)
  // Directory now exists.
})

Not a direct answer, but here is a function to insert a row with column-value pairs into sqlite table:

def sqlite_insert(conn, table, row):
    cols = ', '.join('"{}"'.format(col) for col in row.keys())
    vals = ', '.join(':{}'.format(col) for col in row.keys())
    sql = 'INSERT INTO "{0}" ({1}) VALUES ({2})'.format(table, cols, vals)
    conn.cursor().execute(sql, row)
    conn.commit()

Example of use:

sqlite_insert(conn, 'stocks', {
        'created_at': '2016-04-17',
        'type': 'BUY',
        'amount': 500,
        'price': 45.00})

Note, that table name and column names should be validated beforehand.

try block should be around open. Not around prompt.

while True:
    prompt = input("\n Hello to Sudoku valitator,"
    "\n \n Please type in the path to your file and press 'Enter': ")
    try:
        sudoku = open(prompt, 'r').readlines()
    except FileNotFoundError:
        print("Wrong file or file path")
    else:
        break

argc is the number of command line arguments and argv is array of strings representing command line arguments.

This gives you the option to react to the arguments passed to the program. If you are expecting none, you might as well use int main.

I needed to generate mongodb ids on client side.

After digging into the mongodb source code i found they generate ObjectIDs using npm bson lib.

If ever you need only to generate an ObjectID without installing the whole mongodb / mongoose package, you can import the lighter bson library :

const bson = require('bson');
new bson.ObjectId(); // 5cabe64dcf0d4447fa60f5e2

Note: There is also an npm project named bson-objectid being even lighter

I had this error in code that looked like this:

int A = 1;
int B = A;

The fix is to change it to this

int A = 1;
#define B A

The compiler assigns a location in memory to a variable. The second is trying a assign a second variable to the same location as the first - which makes no sense. Using the macro preprocessor solves the problem.

The following code works fine:

@using (Html.BeginForm("Upload", "Upload", FormMethod.Post, 
                                      new { enctype = "multipart/form-data" }))
{
    @Html.ValidationSummary(true)
    <fieldset>
        Select a file <input type="file" name="file" />
        <input type="submit" value="Upload" />
    </fieldset>
}

and generates as expected:

<form action="/Upload/Upload" enctype="multipart/form-data" method="post">    
    <fieldset>
        Select a file <input type="file" name="file" />
        <input type="submit" value="Upload" />
    </fieldset>
</form>

On the other hand if you are writing this code inside the context of other server side construct such as an if or foreach you should remove the @ before the using. For example:

@if (SomeCondition)
{
    using (Html.BeginForm("Upload", "Upload", FormMethod.Post, 
                                      new { enctype = "multipart/form-data" }))
    {
        @Html.ValidationSummary(true)
        <fieldset>
            Select a file <input type="file" name="file" />
            <input type="submit" value="Upload" />
        </fieldset>
    }
}

As far as your server side code is concerned, here's how to proceed:

[HttpPost]
public ActionResult Upload(HttpPostedFileBase file) 
{
    if (file != null && file.ContentLength > 0) 
    {
        var fileName = Path.GetFileName(file.FileName);
        var path = Path.Combine(Server.MapPath("~/content/pics"), fileName);
        file.SaveAs(path);
    }
    return RedirectToAction("Upload");
}

If you didn't index too much data into the index yet, you can use term facet query on the field that you would like to debug to see the tokens and their frequencies:

curl -XDELETE 'http://localhost:9200/test-idx'
echo
curl -XPUT 'http://localhost:9200/test-idx' -d '
{
    "settings": {
        "index.number_of_shards" : 1,
        "index.number_of_replicas": 0
    },
    "mappings": {            
        "doc": {
            "properties": {
                "message": {"type": "string", "analyzer": "snowball"}
            }
        }
    }

}'
echo
curl -XPUT 'http://localhost:9200/test-idx/doc/1' -d '
{
  "message": "How is this going to be indexed?"
}
'
echo
curl -XPOST 'http://localhost:9200/test-idx/_refresh'
echo
curl -XGET 'http://localhost:9200/test-idx/doc/_search?pretty=true&search_type=count' -d '{
    "query": {
        "match": {
            "_id": "1"
        }
    },
    "facets": {
        "tokens": {
            "terms": {

We can easily setup a Nodejs app by Nginx acting as a reverse proxy.
The following configuration assumes the NodeJS application is running on 127.0.0.1:8080,

  server{
     server_name domain.com sub.domain.com; # multiple domains

     location /{ 
      proxy_pass http://127.0.0.1:8080;  
      proxy_set_header Host $host;
      proxy_pass_request_headers on;  
     }

     location /static/{
       alias /absolute/path/to/static/files; # nginx will handle js/css
     }
   } 

in above setup your Nodejs app will,

• get HTTP_HOST header where you can apply domain specific logic to serve the response. '

• Your Application must be managed by a process manager like pm2 or supervisor for handling situations/reusing sockets or resources etc.

• Setup an error reporting service for getting production errors like sentry or rollbar

NOTE: you can setup logic for handing domain specific request routes, create a middleware for expressjs application

You can use .is(':visible') to test if something is visible and .is(':hidden') to test for the opposite:

$('#offers').toggle(!$('#column-left form').is(':visible')); // or:
$('#offers').toggle($('#column-left form').is(':hidden'));

The easiest way to do it is to link the CSV-file into the Access database as a table. Then you can work on this table as if it was an ordinary access table, for instance by creating an appropriate query based on this table that returns exactly what you want.

You can link the table either manually or with VBA like this

DoCmd.TransferText TransferType:=acLinkDelim, TableName:="tblImport", _
    FileName:="C:\MyData.csv", HasFieldNames:=true

UPDATE

Dim db As DAO.Database

' Re-link the CSV Table
Set db = CurrentDb
On Error Resume Next:   db.TableDefs.Delete "tblImport":   On Error GoTo 0
db.TableDefs.Refresh
DoCmd.TransferText TransferType:=acLinkDelim, TableName:="tblImport", _
    FileName:="C:\MyData.csv", HasFieldNames:=true
db.TableDefs.Refresh

' Perform the import
db.Execute "INSERT INTO someTable SELECT col1, col2, ... FROM tblImport " _
   & "WHERE NOT F1 IN ('A1', 'A2', 'A3')"
db.Close:   Set db = Nothing

Filter using wildcards:

Get-ChildItem -Filter CopyForBuild* -Include *.bat,*.cmd -Exclude *.old.cmd,*.old.bat -Recurse

Filtering using a regular expression:

Get-ChildItem -Path "V:\Myfolder" -Recurse
| Where-Object { $_.Name -match '\ACopyForBuild\.[(bat)|(cmd)]\Z' }

You need to use the WITH RECOVERY option, with your database RESTORE command, to bring your database online as part of the restore process.

This is of course only if you do not intend to restore any transaction log backups, i.e. you only wish to restore a database backup and then be able to access the database.

Your command should look like this,

RESTORE DATABASE MyDatabase
   FROM DISK = 'MyDatabase.bak'
   WITH REPLACE,RECOVERY

You may have more sucess using the restore database wizard in SQL Server Management Studio. This way you can select the specific file locations, the overwrite option, and the WITH Recovery option.

Simply add //noinspection GradleCompatible:

implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
testImplementation 'junit:junit:4.12'
//noinspection GradleCompatible
implementation 'com.android.support:appcompat-v7:28.0.0'

OR

Add the following implementation statements to the dependencies section. (If it shows some App Compat library mismatch error, then we have to re-implement all the mismatching support libraries. We can find the mismatching libraries by place the cursor over the error.Press the shortcut key ctrl + F1 for reveal full details in android studio.)

implementation 'com.android.support:cardview-v7:28.0.0'
implementation 'com.android.support:customtabs:28.0.0'
implementation 'com.android.support:support-media-compat:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'

no need for JOINS:

DELETE m, um FROM messages m, usersmessages um

WHERE m.messageid = 1 

AND m.messageid = um.messageid 

In my index.php I'm loading maybe foobarfunc() like this:

 foobar::foobarfunc();  // Wrong, it is not static method

but can also be

$foobar = new foobar;  // correct
$foobar->foobarfunc();

You can not invoke method this way because it is not static method.

foobar::foobarfunc();

You should instead use:

foobar->foobarfunc();

If however you have created a static method something like:

static $foo; // your top variable set as static

public static function foo() {
    return self::$foo;
}

then you can use this:

foobar::foobarfunc();

you have to use this css property,

 position:relative;

use it for your #contentframe div tag

This is what we use:

public static String getClassResource(Class<?> klass) {
  return klass.getClassLoader().getResource(
     klass.getName().replace('.', '/') + ".class").toString();
}

This will work depending on the ClassLoader implementation: getClass().getProtectionDomain().getCodeSource().getLocation()

While inserting the data, we have to used character string delimiter (' '). And, you missed it (' ') while inserting values which is the reason of your error message. The correction of code is given below:

INSERT INTO LOCATION VALUES(PQ95VM,'HAPPY_STREET','FRANCE');

1 - Create a new folder inside your app and name settings to it.

2 - Now create a new __init__.py file in it and inside it write

from .base import *

try:
    from .local import *
except:
    pass

try:
    from .production import *
except:
    pass

3 - Create three new files in the settings folder name local.py and production.py and base.py.

4 - Inside base.py, copy all the content of previous settings.py folder and rename it with something different, let's say old_settings.py.

5 - In base.py change your BASE_DIR path to point to your new path of setting

Old path-> BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

New path -> BASE_DIR = os.path.dirname(os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

This way, the project dir can be structured and can be manageable among production and local development.

If that is really all the batch file is doing, remove the cmd /K and add PAUSE.

start /B /LOW /WAIT make package
PAUSE

Then, just point your shortcut to "My Batch File.bat"...no need to run it with CMD /K.

UPDATE

Ah, some new info...you're trying to do it from a pinned shortcut on the taskbar.

I found this, Adding Batch Files to Windows 7 Taskbar like the Vista/XP Quick Launch, with the relevant part below.

1. First, pin a shortcut for CMD.EXE to the taskbar by hitting the start button, then type "cmd" in the search box, right-click the result and chose "Pin to Taskbar".
2. Right-click the shortcut on the taskbar.
3. You will see a list that includes "Command Prompt" and "Unpin this program from the taskbar".
4. Right-click the icon for CMD.EXE and select Properties.
5. In the box for Target, go to the end of "%SystemRoot%\system32\cmd.exe" and type " /C " and the path and name of the batch file.

For your purposes, you can either:

1. Use /C and put a PAUSE at the end of your batch file.

   OR

2. Change the command line to use /K and remove the PAUSE from your batch file.

In PostgreSQL we use this approach:

SELECT round(EXTRACT (EPOCH FROM now())::float*1000)

Just add parameters, split by comma:

UPDATE tablename SET column1 = "value1", column2 = "value2" ....

You can use CvInvoke.Resize for Emgu.CV 3.0

e.g

CvInvoke.Resize(inputImage, outputImage, new System.Drawing.Size(100, 100), 0, 0, Inter.Cubic);

I have the same problem like you and luckily I have read the solution from this link: http://access-excel.tips/value-before-worksheet-change/

Dim oldValue As Variant
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
    oldValue = Target.Value
End Sub
Private Sub Worksheet_Change(ByVal Target As Range)
    'do something with oldValue...
End Sub

Note: you must place oldValue variable as a global variable so all subclasses can use it.

May be the better way is

UIColor *color = [UIColor greenColor];
[self.myLabel setTextColor:color];

Thus we have colored text

If you are here because when you tried to upload your fresh/brand new application using the play console it displayed this error: "You must use another package name because "some.package.name" already exists in Google Play."

You just need to go to your build.gradle file (your application) and change

applicationId "some.package.name"

to

applicationId "some.package.different-unique-name"

Other answers here didn't fix this error.

The Java Language Specification⁽¹⁾ describes how try-catch-finally is executed. Having no catch is equivalent to not having a catch able to catch the given Throwable.

• If execution of the try block completes abruptly because of a throw of a value V, then there is a choice:
  • If the run-time type of V is assignable to the parameter of any catch clause of the try statement, then …
    …
  • If the run-time type of V is not assignable to the parameter of any catch clause of the try statement, then the finally block is executed. Then there is a choice:
    • If the finally block completes normally, then the try statement completes abruptly because of a throw of the value V.
    • If the finally block completes abruptly for reason S, then the try statement completes abruptly for reason S (and the throw of value V is discarded and forgotten).

For Android Phones(Without Root):- you can use this application tPacketCapture this will capture the network trafic for your device when you enable the capture. See this url for more details about network sniffing without rooting your device.

Once you have the file which is in .pcap format you can use this file and analyze the traffic using any traffic analyzer like Wireshark.

Also see this post for further ideas on Capturing mobile phone traffic on wireshark

you can try

"usecols" should help, use range of columns (as per excel worksheet, A,B...etc.) below are the examples

1. Selected Columns

df = pd.read_excel(file_location,sheet_name='Sheet1', usecols="A,C,F")

2. Range of Columns and selected column

df = pd.read_excel(file_location,sheet_name='Sheet1', usecols="A:F,H")

3. Multiple Ranges

df = pd.read_excel(file_location,sheet_name='Sheet1', usecols="A:F,H,J:N")

4. Range of columns

df = pd.read_excel(file_location,sheet_name='Sheet1', usecols="A:N")

You can use unbind method to remove handler that has been attached...

if (current = 1){ 
   $('li:eq(2)').unbind('click');
}

You can check what can unbind do ? Unbind manual

To get a count of the number of unique combinations of id, name and address:

SELECT Count(*)
FROM   (
        SELECT DISTINCT
               id
             , name
             , address
        FROM   your_table
       ) As distinctified

While former answer is absolutely correct, I prefer using the JOIN ON syntax to be sure that I know how do I join and on what fields. It would look something like this:

SELECT bc.firstname, bc.lastname, b.title, TO_CHAR(bo.orderdate, 'MM/DD/YYYY') "Order         Date", p.publishername
FROM books b
JOIN book_customer bc ON bc.costumer_id = b.book_id
LEFT JOIN book_order bo ON bo.book_id = b.book_id
(etc.)
WHERE b.publishername = 'PRINTING IS US';

This syntax seperates completely the WHERE clause from the JOIN clause, making the statement more readable and easier for you to debug.

I found it very useful to build also a json message with repeated code, like this:

@POST
@Consumes("application/json")
@Produces("application/json")
public Response authUser(JsonObject authData) {
    String email = authData.getString("email");
    String password = authData.getString("password");
    JSONObject json = new JSONObject();
    if (email.equalsIgnoreCase(user.getEmail()) && password.equalsIgnoreCase(user.getPassword())) {
        json.put("status", "success");
        json.put("code", Response.Status.OK.getStatusCode());
        json.put("message", "User " + authData.getString("email") + " authenticated.");
        return Response.ok(json.toString()).build();
    } else {
        json.put("status", "error");
        json.put("code", Response.Status.NOT_FOUND.getStatusCode());
        json.put("message", "User " + authData.getString("email") + " not found.");
        return Response.status(Response.Status.NOT_FOUND).entity(json.toString()).build();
    }
}

Strings are immutable, meaning their contents cannot change. When you call replace(this,that) you end up with a totally new String. If you want to keep this new copy, you need to assign it to a variable. You can overwrite the old reference (a la sentence = sentence.replace(this,that) or a new reference as seen below:

public class Test{

    public static void main(String[] args) {

        String sentence = "Define, Measure, Analyze, Design and Verify";

        String replaced = sentence.replace("and", "");
        System.out.println(replaced);

    }
}

As an aside, note that I've removed the contains() check, as it is an unnecessary call here. If it didn't contain it, the replace will just fail to make any replacements. You'd only want that contains method if what you're replacing was different than the actual condition you're checking.

Why not just place your button inside of a reference tag e.g

<a href="https://www.google.com/"><button>Next</button></a>

This seems to work perfectly for me and does not add any %20 tags to the link, just how you want it. I have used a link to google to demonstrate.

You could of course wrap this in a form tag but it is not necessary.

When linking another local file just put it in the same folder and add the file name as the reference. Or specify the location of the file if in is not in the same folder.

<a href="myOtherFile"><button>Next</button></a>

This does not add any character onto the end of the URL either, however it does have the files project path as the url before ending with the name of the file. e.g

If my project structure was...

.. denotes a folder - denotes a file while four | denote a sub directory or file in parent folder

..public
|||| ..html
|||| |||| -main.html
|||| |||| -secondary.html

If I open main.html the URL would be,

http://localhost:0000/public/html/main.html?_ijt=i7ms4v9oa7blahblahblah

However, when I clicked the button inside main.html to change to secondary.html, the URL would be,

http://localhost:0000/public/html/secondary.html 

No special characters included at the end of the URL. I hope this helps. By the way - (%20 denotes a space in a URL its encoded and inserted in the place of them.)

Note: The localhost:0000 will obviously not be 0000 you'll have your own port number there.

Furthermore the ?_ijt=xxxxxxxxxxxxxx at the end off the main.html URL, x is determined by your own connection so obviously will not be equal to mine.

It might seem like I'm stating some really basic points but I just want to explain as best as I can. Thank you for reading and I hope this help someone at the very least. Happy programming.

You can do it by using GeometryReader

GeometryReader

Code:

struct ContentView : View {
    var body: some View {
        GeometryReader { geometry in
            VStack {
               Text("Turtle Rock").frame(width: geometry.size.width, height: geometry.size.height, alignment: .topLeading).background(Color.red)
            }
        }
    }
}

Your output like:

Obviously it has been some years this post has been alive - but the fact is I did find it when looking for a similar issue. In our case, we had to add the username / password info to the Security header. This is different from adding header info outside of the Security headers.

The correct way to do this (for custom bindings / authenticationMode="CertificateOverTransport") (as on the .Net framework version 4.6.1), is to add the Client Credentials as usual :

    client.ClientCredentials.UserName.UserName = "[username]";
    client.ClientCredentials.UserName.Password = "[password]";

and then add a "token" in the security binding element - as the username / pwd credentials would not be included by default when the authentication mode is set to certificate.

You can set this token like so:

    //Get the current binding 
    System.ServiceModel.Channels.Binding binding = client.Endpoint.Binding;
    //Get the binding elements 
    BindingElementCollection elements = binding.CreateBindingElements();
    //Locate the Security binding element
    SecurityBindingElement security = elements.Find<SecurityBindingElement>();

    //This should not be null - as we are using Certificate authentication anyway
    if (security != null)
    {
    UserNameSecurityTokenParameters uTokenParams = new UserNameSecurityTokenParameters();
    uTokenParams.InclusionMode = SecurityTokenInclusionMode.AlwaysToRecipient;
security.EndpointSupportingTokenParameters.SignedEncrypted.Add(uTokenParams);
    }

   client.Endpoint.Binding = new CustomBinding(elements.ToArray());

That should do it. Without the above code (to explicitly add the username token), even setting the username info in the client credentials may not result in those credentials passed to the Service.

Your list:

List<MyCustomObject> myCustomObjectList;

Your JSONArray:

// Don't need to loop through it. JSONArray constructor do it for you.
new JSONArray(myCustomObjectList)

Your response:

return new JSONObject().put("yourCustomKey", new JSONArray(myCustomObjectList));

Your post/put http body request would be like this:

    {
        "yourCustomKey: [
           {
               "myCustomObjectProperty": 1
           },
           {
               "myCustomObjectProperty": 2
           }
        ]
    }

The OA can also be implemented in ES6 as follows

ES6:

 const filtered = [1, 2, 3, 4].filter(e => {
    return this.indexOf(e) < 0;
  },[2, 4]);

Use cd with no arguments if you're using the shell directly, or %cd% if you want to use it in a batch file (it behaves like an environment variable).

The MSDN documentation seems to hint that Clone should perform a deep copy, but it is never explicitly stated:

The ICloneable interface contains one member, Clone, which is intended to support cloning beyond that supplied by MemberWiseClone… The MemberwiseClone method creates a shallow copy…

Regardless of what error Oracle SQL Developer may indicate in the syntax highlighting, actually running your alter statement exactly the way you originally had it works perfectly:

ALTER TABLE TEST_PROJECT2 MODIFY proj_name VARCHAR2(300);

You only need to add parenthesis if you need to alter more than one column at once, such as:

ALTER TABLE TEST_PROJECT2 MODIFY (proj_name VARCHAR2(400), proj_desc VARCHAR2(400));

If the previous answers do not solve your problem, check the source of the data that won't print/convert properly.

In my case, I was using json.load on data incorrectly read from file by not using the encoding="utf-8". Trying to de-/encode the resulting string to latin-1 just does not help...

To add or delete elements entirely which would alter the index, by way of extension of zhujy_8833 suggestion of slice() to iterate over a copy, simply count the number of elements you have already deleted or added and alter the index accordingly. For example, to delete elements:

let values = ["A0", "A1", "A2", "A3", "A4", "A5", "A6", "A7", "A8"];
let count = 0;
values.slice().forEach((value, index) => {
    if (value === "A2" || value === "A5") {
        values.splice(index - count++, 1);
    };
});
console.log(values);

// Expected: [ 'A0', 'A1', 'A3', 'A4', 'A6', 'A7', 'A8' ]

To insert elements before:

if (value === "A0" || value === "A6" || value === "A8") {
    values.splice(index - count--, 0, 'newVal');
};

// Expected: ['newVal', A0, 'A1', 'A2', 'A3', 'A4', 'A5', 'newVal', 'A6', 'A7', 'newVal', 'A8' ]

To insert elements after:

if (value === "A0" || value === "A6" || value === "A8") {
    values.splice(index - --count, 0, 'newVal');
};

// Expected: ['A0', 'newVal', 'A1', 'A2', 'A3', 'A4', 'A5', 'A6', 'newVal', 'A7', 'A8', 'newVal']

To replace an element:

if (value === "A3" || value === "A4" || value === "A7") {
    values.splice(index, 1, 'newVal');
};

// Expected: [ 'A0', 'A1', 'A2', 'newVal', 'newVal', 'A5', 'A6', 'newVal', 'A8' ]

Note: if implementing both 'before' and 'after' inserts, code should handle 'before' inserts first, other way around would not be as expected

I ran into this same issue but found out that there is a JSON encoder that can be used to move these objects between processes.

from pyVmomi.VmomiSupport import VmomiJSONEncoder

Use this to create your list:

jsonSerialized = json.dumps(pfVmomiObj, cls=VmomiJSONEncoder)

Then in the mapped function, use this to recover the object:

pfVmomiObj = json.loads(jsonSerialized)

You should use font-size for controlling the height, it is widely supported amongst browsers. And in order to add spacing, you should use padding. Forexample,

.inputField{
  font-size: 30px;
  padding-top: 10px;
  padding-bottom: 10px;
}

To decode characters in Rails use:

<%= raw '<html>' %>

So,

<%= raw '&lt;br&gt;' %>

would output

<br>

Depending on your needs, you could allow both secure and unsecure connections and still only use one Socket.io instance.

You simply have to instanciate two servers, one for HTTP and one for HTTPS, then attach those servers to the Socket.io instance.

Server side :

// needed to read certificates from disk
const fs          = require( "fs"    );

// Servers with and without SSL
const http        = require( "http"  )
const https       = require( "https" );
const httpPort    = 3333;
const httpsPort   = 3334;
const httpServer  = http.createServer();
const httpsServer = https.createServer({
    "key" : fs.readFileSync( "yourcert.key" ),
    "cert": fs.readFileSync( "yourcert.crt" ),
    "ca"  : fs.readFileSync( "yourca.crt"   )
});
httpServer.listen( httpPort, function() {
    console.log(  `Listening HTTP on ${httpPort}` );
});
httpsServer.listen( httpsPort, function() {
    console.log(  `Listening HTTPS on ${httpsPort}` );
});

// Socket.io
const ioServer = require( "socket.io" );
const io       = new ioServer();
io.attach( httpServer  );
io.attach( httpsServer );

io.on( "connection", function( socket ) {

    console.log( "user connected" );
    // ... your code

});

Client side :

var url    = "//example.com:" + ( window.location.protocol == "https:" ? "3334" : "3333" );
var socket = io( url, {
    // set to false only if you use self-signed certificate !
    "rejectUnauthorized": true
});
socket.on( "connect", function( e ) {
    console.log( "connect", e );
});

If your NodeJS server is different from your Web server, you will maybe need to set some CORS headers. So in the server side, replace:

const httpServer  = http.createServer();
const httpsServer = https.createServer({
    "key" : fs.readFileSync( "yourcert.key" ),
    "cert": fs.readFileSync( "yourcert.crt" ),
    "ca"  : fs.readFileSync( "yourca.crt"   )
});

With:

const CORS_fn = (req, res) => {
    res.setHeader( "Access-Control-Allow-Origin"     , "*"    );
    res.setHeader( "Access-Control-Allow-Credentials", "true" );
    res.setHeader( "Access-Control-Allow-Methods"    , "*"    );
    res.setHeader( "Access-Control-Allow-Headers"    , "*"    );
    if ( req.method === "OPTIONS" ) {
        res.writeHead(200);
        res.end();
        return;
    }
};
const httpServer  = http.createServer( CORS_fn );
const httpsServer = https.createServer({
        "key" : fs.readFileSync( "yourcert.key" ),
        "cert": fs.readFileSync( "yourcert.crt" ),
        "ca"  : fs.readFileSync( "yourca.crt"   )
}, CORS_fn );

And of course add/remove headers and set the values of the headers according to your needs.

One gotcha I have found is where two objects contain references to each other (one example being a parent/child relationship with a convenience method on the parent to get all children).
These sorts of things are fairly common when doing Hibernate mappings for example.

If you include both ends of the relationship in your hashCode or equals tests it's possible to get into a recursive loop which ends in a StackOverflowException.
The simplest solution is to not include the getChildren collection in the methods.

The validate plugin will only validate the current/focused element.Therefore you will need to add a custom rule to the validator to validate all the checkboxes. Similar to the answer above.

$.validator.addMethod("roles", function(value, elem, param) {
   return $(".roles:checkbox:checked").length > 0;
},"You must select at least one!");

And on the element:

<input class='{roles: true}' name='roles' type='checkbox' value='1' />

In addition, you will likely find the error message display, not quite sufficient. Only 1 checkbox is highlighted and only 1 message displayed. If you click another separate checkbox, which then returns a valid for the second checkbox, the original one is still marked as invalid, and the error message is still displayed, despite the form being valid. I have always resorted to just displaying and hiding the errors myself in this case.The validator then only takes care of not submitting the form.

The other option you have is to write a function that will change the value of a hidden input to be "valid" on the click of a checkbox and then attach the validation rule to the hidden element. This will only validate in the onSubmit event though, but will display and hide messages at the appropriate times. Those are about the only options that you can use with the validate plugin.

Hope that helps!

A refined version of Moob's post. Create a hash of the POST, save it as a session cookie, and compare hashes every session.

// Optionally Disable browser caching on "Back"
header( 'Cache-Control: no-store, no-cache, must-revalidate' );
header( 'Expires: Sun, 1 Jan 2000 12:00:00 GMT' );
header( 'Last-Modified: ' . gmdate('D, d M Y H:i:s') . 'GMT' );

$post_hash = md5( json_encode( $_POST ) );

if( session_start() )
{
    $post_resubmitted = isset( $_SESSION[ 'post_hash' ] ) && $_SESSION[ 'post_hash' ] == $post_hash;
    $_SESSION[ 'post_hash' ] = $post_hash;
    session_write_close();
}
else
{
    $post_resubmitted = false;
}

if ( $post_resubmitted ) {
  // POST was resubmitted
}
else
{
  // POST was submitted normally
}

Use CAST(GETDATE() as date) that worked for me, simple.

As mentioned in other answers, tuples are immutable once created, and a list might serve your purposes better.

That said, another option for creating a new tuple with extra items is to use the splat operator:

new_tuple = (*old_tuple, 'new', 'items')

I like this syntax because it looks like a new tuple, so it clearly communicates what you're trying to do.

Using splat, a potential solution is:

list = [(*i, ''.join(i)) for i in list]

This simple method solved the problem for me: Copy the content of your dataset, open an empty Excel sheet, choose "Paste Special" -> "Values", and save. Import the new file instead.

(I tried all the existing solutions, and none worked for me. My old dataset appeared to have no missing values, space, special characters, or embedded formulas.)

In comprehension, the nested lists iteration should follow the same order than the equivalent imbricated for loops.

To understand, we will take a simple example from NLP. You want to create a list of all words from a list of sentences where each sentence is a list of words.

>>> list_of_sentences = [['The','cat','chases', 'the', 'mouse','.'],['The','dog','barks','.']]
>>> all_words = [word for sentence in list_of_sentences for word in sentence]
>>> all_words
['The', 'cat', 'chases', 'the', 'mouse', '.', 'The', 'dog', 'barks', '.']

To remove the repeated words, you can use a set {} instead of a list []

>>> all_unique_words = list({word for sentence in list_of_sentences for word in sentence}]
>>> all_unique_words
['.', 'dog', 'the', 'chase', 'barks', 'mouse', 'The', 'cat']

or apply list(set(all_words))

>>> all_unique_words = list(set(all_words))
['.', 'dog', 'the', 'chases', 'barks', 'mouse', 'The', 'cat']

Yes, you must have to open php.ini and remove the semicolon to:

;extension=php_openssl.dll

remove the ";" like this and it will work.

extension=php_openssl.dll

Happy Coding.

This works for me in Raspbian,

echo -e "hello\\nworld"

Usually not with grep, but rather with sed -i 's/string_to_find/another_string/g' or perl -i.bak -pe 's/string_to_find/another_string/g'.

The sessions are handled by the NAS device. What you are asking is dependant on the NAS device and nothing to do with windows. You would have to have a look into your NAS firmware to see to what it support. The only other way is sniff the packets and work it out yourself.

You can use nonHistorySelectors option from jquery mobile where you do not want to track history. You can find the detailed documentation here http://jquerymobile.com/demos/1.0a4.1/#docs/api/globalconfig.html

Usually I would say it is overkill, but there are occasionally reasons for writing unit tests for enums.

Sometimes the values assigned to enumeration members must never change or the loading of legacy persisted data will fail. Similarly, apparently unused members must not be deleted. Unit tests can be used to guard against a developer making changes without realising the implications.

I am also using this approach for csv files (Python 3.6.9):

import csv
import io
import requests

r = requests.get(url)
buff = io.StringIO(r.text)
dr = csv.DictReader(buff)
for row in dr:
    print(row)

def longestWord(some_list): 
    count = 0    #You set the count to 0
    for i in some_list: # Go through the whole list
        if len(i) > count: #Checking for the longest word(string)
            count = len(i)
            word = i
    return ("the longest string is " + word)

or much easier:

max(some_list , key = len)

You are correct that ** is the power function.

^ is bitwise XOR.

% is indeed the modulus operation, but note that for positive numbers, x % m = x whenever m > x. This follows from the definition of modulus. (Additionally, Python specifies x % m to have the sign of m.)

// is a division operation that returns an integer by discarding the remainder. This is the standard form of division using the / in most programming languages. However, Python 3 changed the behavior of / to perform floating-point division even if the arguments are integers. The // operator was introduced in Python 2.6 and Python 3 to provide an integer-division operator that would behave consistently between Python 2 and Python 3. This means:

| context                                | `/` behavior   | `//` behavior |
---------------------------------------------------------------------------
| floating-point arguments, Python 2 & 3 | float division | int divison   |
---------------------------------------------------------------------------
| integer arguments, python 2            | int division   | int division  |
---------------------------------------------------------------------------
| integer arguments, python 3            | float division | int division  |

For more details, see this question: Division in Python 2.7. and 3.3

I'm actually going to be the one guy advocating for the Serializable. The speed difference is not so drastic any more since the devices are far better than several years ago and also there are other, more subtle differences. See my blog post on the issue for more info.

Not Bootstrap specific really... You can use inline styles or define a custom class to specify the desired "background-color".

On the other hand, Bootstrap does have a few built in background colors that have semantic meaning like "bg-success" (green) and "bg-danger" (red).

Did you dispatch the event correctly?

function simulateKeyEvent(character) {
  var evt = document.createEvent("KeyboardEvent");
  (evt.initKeyEvent || evt.initKeyboardEvent)("keypress", true, true, window,
                    0, 0, 0, 0,
                    0, character.charCodeAt(0)) 
  var canceled = !body.dispatchEvent(evt);
  if(canceled) {
    // A handler called preventDefault
    alert("canceled");
  } else {
    // None of the handlers called preventDefault
    alert("not canceled");
  }
}

If you use jQuery, you could do:

function simulateKeyPress(character) {
  jQuery.event.trigger({ type : 'keypress', which : character.charCodeAt(0) });
}

You can do it with a pivot query, like this:

select * from (
   select LOAN_NUMBER, DOCUMENT_TYPE, DOCUMENT_ID
   from my_table t
)
pivot 
(
   MIN(DOCUMENT_ID)
   for DOCUMENT_TYPE in ('Voters ID','Pan card','Drivers licence')
)

Here is a demo on sqlfiddle.com.

UPDLOCK is used when you want to lock a row or rows during a select statement for a future update statement. The future update might be the very next statement in the transaction.

Other sessions can still see the data. They just cannot obtain locks that are incompatiable with the UPDLOCK and/or HOLDLOCK.

You use UPDLOCK when you wan to keep other sessions from changing the rows you have locked. It restricts their ability to update or delete locked rows.

You use HOLDLOCK when you want to keep other sessions from changing any of the data you are looking at. It restricts their ability to insert, update, or delete the rows you have locked. This allows you to run the query again and see the same results.

My solution. Only integral types are allowed.

Update. You can set optional prefix 0x in second parameter.

definition.h

#include  <iomanip>
#include <sstream>

template <class T, class T2 = typename std::enable_if<std::is_integral<T>::value>::type>

    std::stringstream sstream;
    sstream << std::hex;
    std::string ret;

        ret = sstream.str();
        if (ret.length() > 2)

            ret = ret.substr(ret.length() - 2, 2);

You will need wrapper classes:

public class SomeIntInfo
{
    [XmlAttribute]
    public int Value { get; set; }
}

public class SomeStringInfo
{
    [XmlAttribute]
    public string Value { get; set; }
}

public class SomeModel
{
    [XmlElement("SomeStringElementName")]
    public SomeStringInfo SomeString { get; set; }

    [XmlElement("SomeInfoElementName")]
    public SomeIntInfo SomeInfo { get; set; }
}

or a more generic approach if you prefer:

public class SomeInfo<T>
{
    [XmlAttribute]
    public T Value { get; set; }
}

public class SomeModel
{
    [XmlElement("SomeStringElementName")]
    public SomeInfo<string> SomeString { get; set; }

    [XmlElement("SomeInfoElementName")]
    public SomeInfo<int> SomeInfo { get; set; }
}

And then:

class Program
{
    static void Main()
    {
        var model = new SomeModel
        {
            SomeString = new SomeInfo<string> { Value = "testData" },
            SomeInfo = new SomeInfo<int> { Value = 5 }
        };
        var serializer = new XmlSerializer(model.GetType());
        serializer.Serialize(Console.Out, model);
    }
}

will produce:

<?xml version="1.0" encoding="ibm850"?>
<SomeModel xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <SomeStringElementName Value="testData" />
  <SomeInfoElementName Value="5" />

I did a small test a while back with a list vs a hashmap, funny thing was iterating through the list and finding the object took the same amount of time in milliseconds as using the hashmaps get function... just an fyi. Oh yeah memory is a big issue when working with hashmaps that size.

CSS is not a programming language, so the question of turing-completeness is a meaningless one. If programming extensions are added to CSS such as was the case in IE6 then that new synthesis is a whole different thing.

CSS is merely a description of styles; it does not have any logic, and its structure is flat.

There is no such thing as :touch in the W3C specifications, http://www.w3.org/TR/CSS2/selector.html#pseudo-class-selectors

:active should work, I would think.

Order on the :active/:hover pseudo class is important for it to function correctly.

Here is a quote from that above link

Interactive user agents sometimes change the rendering in response to user actions. CSS provides three pseudo-classes for common cases:

• The :hover pseudo-class applies while the user designates an element (with some pointing device), but does not activate it. For example, a visual user agent could apply this pseudo-class when the cursor (mouse pointer) hovers over a box generated by the element. User agents not supporting interactive media do not have to support this pseudo-class. Some conforming user agents supporting interactive media may not be able to support this pseudo-class (e.g., a pen device).
• The :active pseudo-class applies while an element is being activated by the user. For example, between the times the user presses the mouse button and releases it.
• The :focus pseudo-class applies while an element has the focus (accepts keyboard events or other forms of text input).

You mean you have a string of bytes in my_hex which you want to print out as hex numbers, right? E.g., let's take your example:

>>> my_string = "deadbeef"
>>> my_hex = my_string.decode('hex')  # python 2 only
>>> print my_hex
Þ ­ ¾ ï

This construction only works on Python 2; but you could write the same string as a literal, in either Python 2 or Python 3, like this:

my_hex = "\xde\xad\xbe\xef"

So, to the answer. Here's one way to print the bytes as hex integers:

>>> print " ".join(hex(ord(n)) for n in my_hex)
0xde 0xad 0xbe 0xef

The comprehension breaks the string into bytes, ord() converts each byte to the corresponding integer, and hex() formats each integer in the from 0x##. Then we add spaces in between.

Bonus: If you use this method with unicode strings (or Python 3 strings), the comprehension will give you unicode characters (not bytes), and you'll get the appropriate hex values even if they're larger than two digits.

Addendum: Byte strings

In Python 3 it is more likely you'll want to do this with a byte string; in that case, the comprehension already returns ints, so you have to leave out the ord() part and simply call hex() on them:

>>> my_hex = b'\xde\xad\xbe\xef'
>>> print(" ".join(hex(n) for n in my_hex))
0xde 0xad 0xbe 0xef

To automatically format code on save:

• Press Ctrl , to open user preferences

• Enter the following code in the opened settings file

  {
      "editor.formatOnSave": true
  }
  

• Save file

I had solve the issue by revoking my USB debugging authorizations.

To Revoke,

Go to Device Settings > Enable Developer Options > Revoke USB debugging authorizations

I don't know if some of you also use JustMock, but I had to disable the profiler in VS 2017 for test detection to work.

   const fs = require("fs");
   fs.copyFileSync("filepath1", "filepath2"); //fs.copyFileSync("file1.txt", "file2.txt");

This is what I personally use to copy a file and replace another file using Node.js :)

After some research and testing, I found that I had some misunderstandings about the lifetime of Docker containers. Simply restarting a container doesn't make Docker use a new image, when the image was rebuilt in the meantime. Instead, Docker is fetching the image only before creating the container. So the state after running a container is persistent.

Why removing is required

Therefore, rebuilding and restarting isn't enough. I thought containers works like a service: Stopping the service, do your changes, restart it and they would apply. That was my biggest mistake.

Because containers are permanent, you have to remove them using docker rm <ContainerName> first. After a container is removed, you can't simply start it by docker start. This has to be done using docker run, which itself uses the latest image for creating a new container-instance.

Containers should be as independent as possible

With this knowledge, it's comprehensible why storing data in containers is qualified as bad practice and Docker recommends data volumes/mounting host directorys instead: Since a container has to be destroyed to update applications, the stored data inside would be lost too. This cause extra work to shutdown services, backup data and so on.

So it's a smart solution to exclude those data completely from the container: We don't have to worry about our data, when its stored safely on the host and the container only holds the application itself.

Why -rf may not really help you

The docker run command, has a Clean up switch called -rf. It will stop the behavior of keeping docker containers permanently. Using -rf, Docker will destroy the container after it has been exited. But this switch has two problems:

1. Docker also remove the volumes without a name associated with the container, which may kill your data
2. Using this option, its not possible to run containers in the background using -d switch

While the -rf switch is a good option to save work during development for quick tests, it's less suitable in production. Especially because of the missing option to run a container in the background, which would mostly be required.

How to remove a container

We can bypass those limitations by simply removing the container:

docker rm --force <ContainerName>

The --force (or -f) switch which use SIGKILL on running containers. Instead, you could also stop the container before:

docker stop <ContainerName>
docker rm <ContainerName>

Both are equal. docker stop is also using SIGTERM. But using --force switch will shorten your script, especially when using CI servers: docker stop throws an error if the container is not running. This would cause Jenkins and many other CI servers to consider the build wrongly as failed. To fix this, you have to check first if the container is running as I did in the question (see containerRunning variable).

Full script for rebuilding a Docker container

According to this new knowledge, I fixed my script in the following way:

#!/bin/bash
imageName=xx:my-image
containerName=my-container

docker build -t $imageName -f Dockerfile  .

echo Delete old container...
docker rm -f $containerName

echo Run new container...
docker run -d -p 5000:5000 --name $containerName $imageName

This works perfectly :)

You can use the --append feature of tee:

cat file01.txt | tee --append bothFiles.txt 
cat file02.txt | tee --append bothFiles.txt 

Or shorter,

cat file01.txt file02.txt | tee --append bothFiles.txt 

I assume the request for no redirection (>>) comes from the need to use this in xargs or similar. So if that doesn't count, you can mute the output with >/dev/null.

Putting the subquery in the WHERE clause and restricting it to n.control_number means it runs the subquery many times. This is called a correlated subquery, and it's often a performance killer.

It's better to run the subquery once, in the FROM clause, to get the max date per control number.

SELECT n.* 
FROM tblpm n 
INNER JOIN (
  SELECT control_number, MAX(date_updated) AS date_updated
  FROM tblpm GROUP BY control_number
) AS max USING (control_number, date_updated);

window.onload will work like this:

function codeAddress() {_x000D_
 document.getElementById("test").innerHTML=Date();_x000D_
}_x000D_
window.onload = codeAddress;

<!DOCTYPE html>_x000D_
<html>_x000D_
<head>_x000D_
 <title>learning java script</title>_x000D_
 <script src="custom.js"></script>_x000D_
</head>_x000D_
<body>_x000D_
 <p id="test"></p>_x000D_
 <li>abcd</li>_x000D_
</body>_x000D_
</html>

You can change time() to now() for it to work

from datetime import datetime, timedelta
datetime.now() + timedelta(hours=1)

Check this one. It will work.

For the following code you have to enable mssql in the php.ini as described at this link: http://www.php.net/manual/en/mssql.installation.php

$myServer = "10.85.80.229";
$myUser = "root";
$myPass = "pass";
$myDB = "testdb";

$conn = mssql_connect($myServer,$myUser,$myPass);
if (!$conn)
{ 
  die('Not connected : ' . mssql_get_last_message());
} 
$db_selected = mssql_select_db($myDB, $conn);
if (!$db_selected) 
{
  die ('Can\'t use db : ' . mssql_get_last_message());
} 

org.apache.maven.plugins:maven-source-plugin does not exist in the repository http://repo.maven.apache.org/maven2.

You have to download it from Maven central where it exists => maven-source-plugin

Verify your pom definition or your settings.xml file.

I suggest using moment.js which provides an easy to use method for doing this.

interactive demo

function validate(date){
    var eighteenYearsAgo = moment().subtract(18, "years");
    var birthday = moment(date);

    if (!birthday.isValid()) {
        return "invalid date";    
    }
    else if (eighteenYearsAgo.isAfter(birthday)) {
        return "okay, you're good";    
    }
    else {
        return "sorry, no";    
    }
}

To include moment in your page, you can use CDNJS:

<script src="//cdnjs.cloudflare.com/ajax/libs/moment.js/2.4.0/moment.min.js"></script>

You should be able to add:

restart: always 

to every service you want to restart in the docker-compose.yml file.

See: https://github.com/compose-spec/compose-spec/blob/master/spec.md#restart

In my humble opinion the best way is to just add a full day in milliseconds, depending on how you factor your code it can mess up if your on the last day of the month.

for example Feb 28 or march 31.

Here is an example of how i would do it:

var current = new Date(); //'Mar 11 2015' current.getTime() = 1426060964567
var followingDay = new Date(current.getTime() + 86400000); // + 1 day in ms
followingDay.toLocaleDateString();

imo this insures accuracy

here is another example i Do not like that can work for you but not as clean that dose the above

var today = new Date('12/31/2015');
var tomorrow = new Date(today);
tomorrow.setDate(today.getDate()+1);
tomorrow.toLocaleDateString();

imho this === 'POOP'

So some of you have had gripes about my millisecond approach because of day light savings time. So Im going to bash this out. First, Some countries and states do not have Day light savings time. Second Adding exactly 24 hours is a full day. If the date number dose not change once a year but then gets fixed 6 months later i don't see a problem there. But for the purpose of being definite and having to deal with allot the evil Date() i have thought this through and now thoroughly hate Date. So this is my new Approach

var dd = new Date(); // or any date and time you care about 
var dateArray =  dd.toISOString().split('T')[0].split('-').concat( dd.toISOString().split('T')[1].split(':') );
// ["2016", "07", "04", "00", "17", "58.849Z"] at Z 

Now for the fun part!

var date = { 
    day: dateArray[2],
    month: dateArray[1],
    year: dateArray[0],
    hour: dateArray[3],
    minutes: dateArray[4],
    seconds:dateArray[5].split('.')[0],
    milliseconds: dateArray[5].split('.')[1].replace('Z','')
}

now we have our Official Valid international Date Object clearly written out at Zulu meridian. Now to change the date

  dd.setDate(dd.getDate()+1); // this gives you one full calendar date forward
  tomorrow.setDate(dd.getTime() + 86400000);// this gives your 24 hours into the future. do what you want with it.

For those of you on Windows using TortoiseGit, you can get a somewhat visual comparison through this rather obscure feature:

1. Navigate to the folder you want to compare
2. Hold down shift and right-click it
3. Go to TortoiseGit -> Browse Reference
4. Use ctrl to select two branches to compare
5. Right-click your selection and click "Compare selected refs"
