Yes.

However, if you need to use Application.DoEvents, this is mostly an indication of a bad application design. Perhaps you'd like to do some work in a separate thread instead?

Since you have the manual user input loop, after the scanner has read your first input it will pass the carriage/return into the next line which will also be read; of course, that is not what you wanted.

You can try this

try {
    // ...
} catch (InputMismatchException e) {
    reader.next(); 
}

or alternatively, you can consume that carriage return before reading your next double input by calling

reader.next()

Get the system time in milliseconds at the beginning, and again at the end, and subtract.

To get the number of milliseconds since 1970 in POSIX you would write:

struct timeval tv;

gettimeofday(&tv, NULL);
return ((((unsigned long long)tv.tv_sec) * 1000) +
        (((unsigned long long)tv.tv_usec) / 1000));

To get the number of milliseconds since 1601 on Windows you would write:

SYSTEMTIME systime;
FILETIME filetime;

GetSystemTime(&systime);
if (!SystemTimeToFileTime(&systime, &filetime))
    return 0;

unsigned long long ns_since_1601;
ULARGE_INTEGER* ptr = (ULARGE_INTEGER*)&ns_since_1601;

// copy the result into the ULARGE_INTEGER; this is actually
// copying the result into the ns_since_1601 unsigned long long.
ptr->u.LowPart = filetime.dwLowDateTime;
ptr->u.HighPart = filetime.dwHighDateTime;

// Compute the number of milliseconds since 1601; we have to
// divide by 10,000, since the current value is the number of 100ns
// intervals since 1601, not ms.
return (ns_since_1601 / 10000);

If you cared to normalize the Windows answer so that it also returned the number of milliseconds since 1970, then you would have to adjust your answer by 11644473600000 milliseconds. But that isn't necessary if all you care about is the elapsed time.

The three dot (...) notation is actually borrowed from mathematics, and it means "...and so on".

As for its use in Java, it stands for varargs, meaning that any number of arguments can be added to the method call. The only limitations are that the varargs must be at the end of the method signature and there can only be one per method.

You can use addition to concatenate strings.

Strings are added by being joined into a larger string.

jq '.users[] | .first + " " + .last'

The above works when both first and last are string. If you are extracting different datatypes(number and string), then we need to convert to equivalent types. Referring to solution on this question. For example.

jq '.users[] | .first + " " + (.number|tostring)'

Enumerations are used to represent a set of integer values.

The class keyword after the enum specifies that the enumeration is strongly typed and its enumerators are scoped. This way enum classes prevents accidental misuse of constants.

For Example:

enum class Animal{Dog, Cat, Tiger};
enum class Pets{Dog, Parrot};

Here we can not mix Animal and Pets values.

Animal a = Dog;       // Error: which DOG?    
Animal a = Pets::Dog  // Pets::Dog is not an Animal

I like to disable paging from time to time, when I know the output is not very long. For this, I found a neat trick using Git aliases:

git config --global --add alias.n '!git --no-pager'

Or add the following to the [alias] section of ~/.gitconfig:

n = !git --no-pager

This means that you can use the prefix n to turn off paging for any Git command, i.e.:

git n diff # Show the diff without pager
git n log -n 3 # Show the last three commits without pager
git n show v1.1 # Show information about a tag

Just use git reset without the --hard flag:

git reset HEAD~1

PS: On Unix based systems you can use HEAD^ which is equal to HEAD~1. On Windows HEAD^ will not work because ^ signals a line continuation. So your command prompt will just ask you More?.

If you want absolute urls, you have the third parameter.

$product_url = $this->generateUrl('product_detail', 
    array(
        'slug' => 'slug'
    ),
    UrlGeneratorInterface::ABSOLUTE_URL
);

Remember to include UrlGeneratorInterface.

use Symfony\Component\Routing\Generator\UrlGeneratorInterface;

Adding a bit more to above-mentioned answers.

id of a variable changes upon reassignment.

>>> a = 'initial_string'
>>> id(a)
139982120425648
>>> a = 'new_string'
>>> id(a)
139982120425776

Which means that we have mutated the variable a to point to a new string. Now there exist two string(str) objects:

'initial_string' with id = 139982120425648

and

'new_string' with id = 139982120425776

Consider the below code:

>>> b = 'intitial_string'
>>> id(b)
139982120425648

Now, b points to the 'initial_string' and has the same id as a had before reassignment.

Thus, the 'intial_string' has not been mutated.

Not enough rep for a comment.

The getElementById() based method in the selected answer won't work if the anchor has name but not id set (which is not recommended, but does happen in the wild).

Something to bare in mind if you don't have control of the document markup (e.g. webextension).

The location based method in the selected answer can also be simplified with location.replace:

function jump(hash) { location.replace("#" + hash) }

If you know the array index, you can delete() it. The difference between splice() and delete() is that delete() does not renumber the remaining elements of the array.

For Laravel 5.5+

Controller:

return redirect()->back()->with('success', 'your message here');

Blade:

@if (Session::has('success'))
    <div class="alert alert-success">
        <ul>
            <li>{{ Session::get('success') }}</li>
        </ul>
    </div>
@endif

The above answers are partially correct, but with "tel://" there is only one issue. After the call has ended, it will return to the homescreen, not to our app. So better to use "telprompt://", it will return to the app.

var url:NSURL = NSURL(string: "telprompt://1234567891")!
UIApplication.sharedApplication().openURL(url)

There is a difference.

When the ^ character appears outside of [] matches the beginning of the line (or string). When the ^ character appears inside the [], it matches any character not appearing inside the [].

I have checked a variable if it is a boolean or not as below

console.log(isBoolean(this.myVariable));

Similarly we have

isNumber(this.myVariable);
isString(this.myvariable);

and so on.

tests are supposed to improve maintainability. If you change a method and a test breaks that can be a good thing. On the other hand, if you look at your method as a black box then it shouldn't matter what is inside the method. The fact is you need to mock things for some tests, and in those cases you really can't treat the method as a black box. The only thing you can do is to write an integration test -- you load up a fully instantiated instance of the service under test and have it do its thing like it would running in your app. Then you can treat it as a black box.

When I'm writing tests for a method, I have the feeling of rewriting a second time what I          
already wrote in the method itself.
My tests just seems so tightly bound to the method (testing all codepath, expecting some    
inner methods to be called a number of times, with certain arguments), that it seems that
if I ever refactor the method, the tests will fail even if the final behavior of the   
method did not change.

This is because you are writing your tests after you wrote your code. If you did it the other way around (wrote the tests first) it wouldnt feel this way.

In case you actually mean what you seem to ask, I'll provide this alternative answer.

You say you want the dict to return a specified value, you do not say you want to set that value at the same time, like defaultdict does. This will do so:

class DictWithDefault(dict):
    def __init__(self, default, **kwargs):
        self.default = default
        super(DictWithDefault, self).__init__(**kwargs)

    def __getitem__(self, key):
        if key in self:
            return super(DictWithDefault, self).__getitem__(key)
        return self.default

Use like this:

d = DictWIthDefault(99, x=5, y=3)
print d["x"]   # 5
print d[42]    # 99
42 in d        # False
d[42] = 3
42 in d        # True

Alternatively, you can use a standard dict like this:

d = {3: 9, 4: 2}
default = 99
print d.get(3, default)  # 9
print d.get(42, default) # 99

You can fill an array with arrays using a function:

var arr = [];
var rows = 11;
var columns = 12;

fill2DimensionsArray(arr, rows, columns);

function fill2DimensionsArray(arr, rows, columns){
    for (var i = 0; i < rows; i++) {
        arr.push([0])
        for (var j = 0; j < columns; j++) {
            arr[i][j] = 0;
        }
    }
}

The result is:

Array(11)
0:(12) [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
1:(12) [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
2:(12) [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
3:(12) [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
4:(12) [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
5:(12) [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
6:(12) [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
7:(12) [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
8:(12) [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
9:(12) [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
10:(12)[0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]

In my case, this has been resolved by going to control panel > java > security > then add url in the exception site list. Then apply. Test again the site and it should now allow you to run the local java.

One simple solution:

cond1 <- df$sub == 1 & df$day == 2

cond2 <- df$sub == 3 & df$day == 4

df <- df[!(cond1 | cond2),]

Supplementary for option 4 by @fenton, using angularJS it is rather simple to do a deep copy of either an object or array using the following code:

var deepCopy = angular.copy(objectOrArrayToBeCopied)

More documentation can be found here: https://docs.angularjs.org/api/ng/function/angular.copy

// Two different dates
var date1 = new Date(2013, 05, 13); 
var date2 = new Date(2013, 04, 10) ;
// convert both dates in milliseconds and use Math.min function
var minDate = Math.min(date1.valueOf(), date2.valueOf());
// convert minDate to Date
var date = new Date(minDate);

Thanks guys. I solved this problem through your help. So, I hope this screenshot helpful to person who have same problem.

Not knowing quite what the 'answer' command did, I ran it, much to my dismay. It recursively removes every file from your git repo.

Stackoverflow to the rescue... How to revert a "git rm -r ."?

git reset HEAD

Did the trick, since I had uncommitted local files that I didn't want to overwrite.

Look at these lines:

If yes_ans > no_ans and yes_ans > na_ans

and similar. To what do "yes_ans" etc. refer? You're not using these in the context of a query; the "if exists" condition doesn't extend to the column names you're using inside.

Consider assigning those values to variables you can then use for your conditional flow below. Thus,

if exists (some record)
begin
   set @var = column, @var2 = column2, ...

   if (@var1 > @var2)
      -- do something

end

The return type is also mismatched with the declaration. It would help a lot if you indented, used ANSI-standard punctuation (terminate statements with semicolons), and left out superfluous begin/end - you don't need these for single-statement lines executed as the result of a test.

Google used to recommend putting it just before the </body> tag, because the original method they provided for loading ga.js was blocking. The newer async syntax, though, can safely be put in the head with minimal blockage, so the current recommendation is just before the </head> tag.

<head> will add a little latency; in the footer will reduce the number of pageviews recorded at some small margin. It's a tradeoff. ga.js is heavily cached and present on a large percentage of sites across the web, so its often served from the cache, reducing latency to almost nil.

As a matter of personal preference, I like to include it in the <head>, but its really a matter of preference.

Although the answers are received, I would wish to discuss about network errors in MongoDB.

Setting the safe write concerns is not the full proof method to make sure that we're safe. Let's assume that w=1 & j=true are set, what if the write acknowledgement didn't received from the server? Well, the likelyhood is it didn't happened, but it might have happened. The reason why this might have happened is that there are network errors - there are reasons that we may not receive an affirmative response. So, we can send the request from the application through a driver of language of choice. mongod can complete it successfully and then there could be a TCP reset, and the network actually can get reset in a way that we never receive response. So, we could get an error and on the error, we might assume that we got an error. It didn't happened, but it may happen.

For an insert, it's possible to guard against it. It's possible because if we let the driver create the _id and we do an insert - then we could do that insert multiple times and it would be any harm. Because, if we do this 1^st time and we get an error and we're not sure whether or not that insert completed because it's a network error, then we could just do it again. And provided we perform it again, tyr to perform it with the exact _id. The worst case scenario is we'll get a duplicate key error when we try to insert it.

However, an update is where the problem occurs. Especially, the update which is not item potent, that for instance included a $ink command. So, we're telling the database to increment a certain field. Well in that case, if we get a network error and we don't know whether or not the update occurred. Now, maybe we know enough about the values that we can check with them that the update occurred, which is fine. But if we don't know the starting value in the database for that field, then it's not possible for us to know whether or not it occurred or not in case of network error. This kind of issues are extremely rare with a fine network.

And if we really need to avoid it at all costs, what we need to do is turn on all our updates into inserts, by reading the full value of the document out of the database and then potentially deleting it and inserting it again or just inserting a new one.

The reasons why an application may receive an error back even if the write was successful:

• The network TCP connection between the application and the server was reset after the server received a write but before a response could be sent.
• The MongoDB server terminates between receiving the write and responding to it.
• The network fails between the time of the write and the time the client receives a response to the write.

You can use it to transform some aggregate functions into analytic:

SELECT  MAX(date)
FROM    mytable

will return 1 row with a single maximum,

SELECT  MAX(date) OVER (ORDER BY id)
FROM    mytable

will return all rows with a running maximum.

If you know the process name you can use:

killall Dock

If you don't you can open Activity Monitor and find it.

Another reason + solution

I run into this error ("package XXX is not available for R version X.X.X") when trying to install pkgdown in my RStudio on my company's HPC.

Turns out, the CRAN snapshot they have on the HPC is from Jan. 2018 (almost 2 years old) and indeed pkgdown did not exist then. That was meant to control the source of packages for layman users, but as a developer, you can in most cases change that by:

## checking the specific repos you currently have
getOption("repos")

## updating your CRAN snapshot to a newer date
r <- getOption("repos")
r["newCRAN"] <- "https://cran.microsoft.com/snapshot/*2019-11-07*/"
options(repos = r)

## add newCRAN to repos you can use
setRepositories()

If you know what you are doing and may need more than one package that might not be available in your system's CRAN, you can set this up in your project .Rprofile.

If it's just one package, maybe just use install.packages("package name", repos = "a newer CRAN than your company's archaic CRAN snapshot").

queryItems.AllKeys.Contains(key)

Be aware that key may not be unique and that the comparison is usually case sensitive. If you want to just get the value of the first matching key and not bothered about case then use this:

        public string GetQueryValue(string queryKey)
        {
            foreach (string key in QueryItems)
            {
                if(queryKey.Equals(key, StringComparison.OrdinalIgnoreCase))
                    return QueryItems.GetValues(key).First(); // There might be multiple keys of the same name, but just return the first match
            }
            return null;
        }

You can add these style's and it works just as expected.

.btn {
    white-space:normal !important; 
    word-wrap: break-word; 
    word-break: normal;
}

Note: This answer refers/adds to Sotirios Delimanolis's answer and comment.

I tried to get it to work with Map<Class, ParameterizedTypeReference<ResponseWrapper<?>>>, as indicated in Sotirios's comment, but couldn't without an example.

In the end, I dropped the wildcard and parametrisation from ParameterizedTypeReference and used raw types instead, like so

Map<Class<?>, ParameterizedTypeReference> typeReferences = new HashMap<>();
typeReferences.put(MyClass1.class, new ParameterizedTypeReference<ResponseWrapper<MyClass1>>() { });
typeReferences.put(MyClass2.class, new ParameterizedTypeReference<ResponseWrapper<MyClass2>>() { });

...

ParameterizedTypeReference typeRef = typeReferences.get(clazz);

ResponseEntity<ResponseWrapper<T>> response = restTemplate.exchange(
        uri, 
        HttpMethod.GET, 
        null, 
        typeRef);

and this finally worked.

If anyone has an example with parametrisation, I'd be very grateful to see it.

The substring starts at, and includes the character at the location of the first number given and goes to, but does not include the character at the last number given.

You can load HTML page partial, in your case is everything inside div#mytable.

setTimeout(function(){
   $( "#mytable" ).load( "your-current-page.html #mytable" );
}, 2000); //refresh every 2 seconds

more information read this http://api.jquery.com/load/

Update Code (if you don't want it auto-refresh)

<button id="refresh-btn">Refresh Table</button>

<script>
$(document).ready(function() {

   function RefreshTable() {
       $( "#mytable" ).load( "your-current-page.html #mytable" );
   }

   $("#refresh-btn").on("click", RefreshTable);

   // OR CAN THIS WAY
   //
   // $("#refresh-btn").on("click", function() {
   //    $( "#mytable" ).load( "your-current-page.html #mytable" );
   // });


});
</script>

The program, albeit its errors, shows proof that a GUID is not unique. Those that try to prove the contrary are missing the point. This statement just proves the weak implementation of some of the GUID variations.

A GUID is not necessary unique by definition, it is highly unique by definition. You just refined the meaning of highly. Depending on the version, the implementator (MS or others), use of VM's, etc your definition of highly changes. (see link in earlier post)

You can shorten your 128 bit table to prove your point. The best solution is to use a hash formula to shorten your table with duplicates, and then use the full value once the hash collides and based on that re-generate a GUID. If running from different locations, you would be storing your hash/full key pairs in a central location.

Ps: If the goal is just to generate x number of different values, create a hash table of this width and just check on the hash value.

@GavinSimpson: reorder is a powerful and effective solution for this:

ggplot(theTable,
       aes(x=reorder(Position,Position,
                     function(x)-length(x)))) +
       geom_bar()

You could try:

#applyCSS .ui-bar-a {property:value}
#applyCSS .ui-bar-a .ui-link-inherit {property:value}

Etc, etc... Is that what you're looking for?

To understand this let's consider an example where we have a class Mammal which defines readAndGet method which is reading some file, doing some operation on it and returning an instance of class Mammal.

class Mammal {
    public Mammal readAndGet() throws IOException {//read file and return Mammal`s object}
}

Class Human extends class Mammal and overrides readAndGet method to return the instance of Human instead of the instance of Mammal.

class Human extends Mammal {
    @Override
    public Human readAndGet() throws FileNotFoundException {//read file and return Human object}
}

To call readAndGet we will need to handle IOException because its a checked exception and mammal's readAndMethod is throwing it.

Mammal mammal = new Human();
try {
    Mammal obj = mammal.readAndGet();
} catch (IOException ex) {..}

And we know that for compiler mammal.readAndGet() is getting called from the object of class Mammal but at, runtime JVM will resolve mammal.readAndGet() method call to a call from class Human because mammal is holding new Human().

Method readAndMethod from Mammal is throwing IOException and because it is a checked exception compiler will force us to catch it whenever we call readAndGet on mammal

Now suppose readAndGet in Human is throwing any other checked exception e.g. Exception and we know readAndGet will get called from the instance of Human because mammal is holding new Human().

Because for compiler the method is getting called from Mammal, so the compiler will force us to handle only IOException but at runtime we know method will be throwing Exception exception which is not getting handled and our code will break if the method throws the exception.

That's why it is prevented at the compiler level itself and we are not allowed to throw any new or broader checked exception because it will not be handled by JVM at the end.

There are other rules as well which we need to follow while overriding the methods and you can read more on Why We Should Follow Method Overriding Rules to know the reasons.

SOAP, pros and cons

About SOAP 1.2, advantages and drawbacks when comparing with "REST"... Well, since 2007 you can describe REST Web services with WSDL, and using SOAP protocol... That is, if you work a little harder, all W3C standards of the web services protocol stack can be REST!

It is a good starting point, because we can imagine a scenario in which all the philosophical and methodological discussions are temporarily avoided. We can compare technically "SOAP-REST" with "NON-SOAP-REST" in similar services,

• SOAP-REST (="REST-SOAP"): as showed by L.Mandel, WSDL2 can describe a REST webservice, and, if we suppose that exemplified XML can be enveloped in SOAP, all the implementation will be "SOAP-REST".

• NON-SOAP-REST: any REST web service that can not be SOAP... That is, "90%" of the well-knowed REST examples. Some not use XML (ex. typical AJAX RESTs use JSON instead), some use another XML strucutures, without the SOAP headers or rules. PS: to avoid informality, we can suppose REST level 2 in the comparisons.

Of course, to compare more conceptually, compare "NON-REST-SOAP" with "NON-SOAP-REST", as different modeling approaches. So, completing this taxonomy of web services:

• NON-REST-SOAP: any SOAP web service that can not be REST... That is, "90%" of the well-knowed SOAP examples.

• NON-REST-NEITHER-SOAP: yes, the universe of "web services modeling" comprises other things (ex. XML-RPC).

SOAP in the REST condictions

Comparing comparable things: SOAP-REST with NON-SOAP-REST.

PROS

Explaining some terms,

• Contractual stability: for all kinds of contracts (as "written agreements"),

  • By the use of standars: all levels of the W3C stack are mutually compliant. REST, by other hand, is not a W3C or ISO standard, and have no normatized details about service's peripherals. So, as I, @DaveWoldrich(20 votes), @cynicalman(5), @Exitos(0) said before, in a context where are NEED FOR STANDARDS, you need SOAP.

  • By the use of best practices: the "verbose aspect" of the W3C stack implementations, translates relevant human/legal/juridic agreements.

• Robustness: the safety of SOAP structure and headers. With metada communication (with the full expressiveness of XML) and verification you have an "insurance policy" against any changes or noise.
  SOAP have "transactional reliability (...) deal with communication failures. SOAP has more controls around retry logic and thus can provide more end-to-end reliability and service guarantees", E. Terman.

Sorting pros by popularity,

• Better tools (~70 votes): SOAP currently has the advantage of better tools, since 2007 and still 2012, because it is a well-defined and widely accepted standard. See @MarkCidade(27 votes), @DaveWoldrich(20), @JoshM(13), @TravisHeseman(9).

• Standars compliance (25 votes): as I, @DaveWoldrich(20 votes), @cynicalman(5), @Exitos(0) said before, in a context where are NEED FOR STANDARDS, you need SOAP.

• Robustness: insurance of SOAP headers, @JohnSaunders (8 votes).

CONS

• SOAP strucuture is more complex (more than 300 votes): all answers here, and sources about "SOAP vs REST", manifest some degree of dislike with SOAP's redundancy and complexity. This is a natural consequence of the requirements for formal verification (see below), and for robustness (see above). "REST NON-SOAP" (and XML-RPC, the SOAP originator) can be more simple and informal.

• The "only XML" restriction is a performance obstacle when using tiny services (~50 votes): see json.org/xml and this question, or this other one. This point is showed by @toluju(41), and others.
  PS: as JSON is not a IETF standard, but we can consider a de facto standard for web software community.

Modeling services with SOAP

Now, we can add SOAP-NON-REST with NON-SOAP-REST comparisons, and explain when is better to use SOAP:

• Need for standards and stable contracts (see "PROS" section). PS: see a typical "B2B need for standards" described by @saille.

• Need for tools (see "PROS" section). PS: standards, and the existence of formal verifications (see bellow), are important issues for the tools automation.

• Parallel heavy processing (see "Context/Foundations" section below): with bigger and/or slower processes, no matter with a bit more complexity of SOAP, reliability and stability are the best investments.

• Need more security: when more than HTTPS is required, and you really need additional features for protection, SOAP is a better choice (see @Bell, 32 votes). "Sending the message along a path more complicated than request/response or over a transport that does not involve HTTP", S. Seely. XML is a core issue, offering standards for XML Encryption, XML Signature, and XML Canonicalization, and, only with SOAP you can to embed these mechanisms into a message by a well-accepted standard as WS-Security.

• Need more flexibility (less restrictions): SOAP not need exact correspondence with an URI; not nedd restrict to HTTP; not need to restrict to 4 verbs. As @TravisHeseman (9 votes) says, if you wanted something "flexible for an arbitrary number of client technologies and uses", use SOAP.
  PS: remember that XML is more universal/expressive than JSON (et al).

• Need for formal verifications: important to understand that W3C stack uses formal methods, and REST is more informal. Your WSDL (a formal language) service description is a formal specification of your web services interfaces, and SOAP is a robust protocol that accept all possible WSDL prescriptions.

CONTEXT

Historical

To assess trends is necessary historical perspective. For this subject, a 10 or 15 years perspective...

Before the W3C standardization, there are some anarchy. Was difficult to implement interoperable services with different frameworks, and more difficult, costly, and time consuming to implement something interoperable between companys. The W3C stack standards has been a light, a north for interoperation of sets of complex web services.

For day-by-day tasks, like to implement AJAX, SOAP is heavy... So, the need for simple approaches need to elect a new theory-framework... And big "Web software players", as Google, Amazon, Yahoo, et al, elected the best alternative, that is the REST approach. Was in this context that REST concept arrived as a "competing framework", and, today (2012's), this alternative is a de facto standard for programmers.

Foundations

In a context of Parallel Computing the web services provides parallel subtasks; and protocols, like SOAP, ensures good synchronization and communication. Not "any task": web services can be classified as
coarse-grained and embarrassing parallelism.

As the task gets bigger, it becomes less significant "complexity debate", and becomes more relevant the robustness of the communication and the solidity of the contracts.

You need the table name/alias in the SELECT part (maybe (vg.id, name)) :

SELECT (vg.id, name) FROM v_groups vg 
inner join people2v_groups p2vg on vg.id = p2vg.v_group_id
where p2vg.people_id =0;

.btn{
    font-size: 20px;

Use

find \( -path "./tmp" -o -path "./scripts" \) -prune -o  -name "*_peaks.bed" -print

or

find \( -path "./tmp" -o -path "./scripts" \) -prune -false -o  -name "*_peaks.bed"

or

find \( -path "./tmp" -path "./scripts" \) ! -prune -o  -name "*_peaks.bed"

The order is important. It evaluates from left to right. Always begin with the path exclusion.

Explanation

Do not use -not (or !) to exclude whole directory. Use -prune. As explained in the manual:

-prune    The primary shall always evaluate as  true;  it
          shall  cause  find  not  to descend the current
          pathname if it is a directory.  If  the  -depth
          primary  is specified, the -prune primary shall
          have no effect.

and in the GNU find manual:

-path pattern
              [...]
              To ignore  a  whole
              directory  tree,  use  -prune rather than checking
              every file in the tree.

Indeed, if you use -not -path "./pathname", find will evaluate the expression for each node under "./pathname".

find expressions are just condition evaluation.

• \( \) - groups operation (you can use -path "./tmp" -prune -o -path "./scripts" -prune -o, but it is more verbose).
• -path "./script" -prune - if -path returns true and is a directory, return true for that directory and do not descend into it.
• -path "./script" ! -prune - it evaluates as (-path "./script") AND (! -prune). It revert the "always true" of prune to always false. It avoids printing "./script" as a match.
• -path "./script" -prune -false - since -prune always returns true, you can follow it with -false to do the same than !.
• -o - OR operator. If no operator is specified between two expressions, it defaults to AND operator.

Hence, \( -path "./tmp" -o -path "./scripts" \) -prune -o -name "*_peaks.bed" -print is expanded to:

[ (-path "./tmp" OR -path "./script") AND -prune ] OR ( -name "*_peaks.bed" AND print )

The print is important here because without it is expanded to:

{ [ (-path "./tmp" OR -path "./script" )  AND -prune ]  OR (-name "*_peaks.bed" ) } AND print

-print is added by find - that is why most of the time, you do not need to add it in you expression. And since -prune returns true, it will print "./script" and "./tmp".

It is not necessary in the others because we switched -prune to always return false.

Hint: You can use find -D opt expr 2>&1 1>/dev/null to see how it is optimized and expanded,
find -D search expr 2>&1 1>/dev/null to see which path is checked.

It doesn't look like it's possible to not have the certificate error any more. I'm on Windows XP with IE 8. Group Policy had installed a self-signed certificate as a trusted root certificate for access to an internal site. When I look at MMC with the certificate snap-in I can see the certificate there OK.

When I look at:

Internet Options => Content => certificates

It isn't there!

This behaviour in IE started since our admins let loose with the last lot of Patch-Tuesday updates which installed on my machine on 10th Dec 2009. Prior to that it was quite happy to accept the certificate as valid.

SQL is a standard and there are many database vendors like Microsoft,Oracle who implements this standard using their own proprietary language.

Microsoft uses T-SQL to implement SQL standard to interact with data whereas oracle uses PL/SQL.

The easiest way to do so is installing an older SDK to your newest Xcode.

How to install older SDK to the newest Xcode?

1. U can get the iOS 6.1 SDK from http://www.4shared.com/zip/NlPgsxz6/iPhoneOS61sdk.html or downloading an older Xcode and geting the SDK from its contents

2. Unzip and paste this folder to /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs

3. Restart the xcode.

4. U can now select an older SDK on your project's build settings

Hope it helps you. It worked for me =)

You'll need to create an array of the values in the enum, which can be created by calling System.Enum.GetValues(), passing it the Type of the enum that you want the items of.

If you specify this for the ItemsSource property, then it should be populated with all of the enum's values. You probably want to bind SelectedItem to EffectStyle (assuming it is a property of the same enum, and contains the current value).

This error message is always caused by the invalid XML content in the beginning element. For example, extra small dot “.” in the beginning of XML element.

Any characters before the “<?xml….” will cause above “org.xml.sax.SAXParseException: Content is not allowed in prolog” error message.

A small dot “.” before the “<?xml….

To fix it, just delete all those weird characters before the “<?xml“.

if anyone else has problem with the above mentioned solutions, I ended up just going for the event:

$("#jquery_audioPlayer").jPlayer({
    ready:function () {
        $(this).jPlayer("setMedia", {
            mp3:"media/song.mp3"
        })
        ...
    pause: function () {
      $('#yoursoundcontrol').click(function () {
            $("#jquery_audioPlayer").jPlayer('play');
      })
    },
    play: function () {
    $('#yoursoundcontrol').click(function () {
            $("#jquery_audioPlayer").jPlayer('pause');
    })}
});

works for me.

REST means working with the standards of the web, and the standard for "secure" transfer on the web is SSL. Anything else is going to be kind of funky and require extra deployment effort for clients, which will have to have encryption libraries available.

Once you commit to SSL, there's really nothing fancy required for authentication in principle. You can again go with web standards and use HTTP Basic auth (username and secret token sent along with each request) as it's much simpler than an elaborate signing protocol, and still effective in the context of a secure connection. You just need to be sure the password never goes over plain text; so if the password is ever received over a plain text connection, you might even disable the password and mail the developer. You should also ensure the credentials aren't logged anywhere upon receipt, just as you wouldn't log a regular password.

HTTP Digest is a safer approach as it prevents the secret token being passed along; instead, it's a hash the server can verify on the other end. Though it may be overkill for less sensitive applications if you've taken the precautions mentioned above. After all, the user's password is already transmitted in plain-text when they log in (unless you're doing some fancy JavaScript encryption in the browser), and likewise their cookies on each request.

Note that with APIs, it's better for the client to be passing tokens - randomly generated strings - instead of the password the developer logs into the website with. So the developer should be able to log into your site and generate new tokens that can be used for API verification.

The main reason to use a token is that it can be replaced if it's compromised, whereas if the password is compromised, the owner could log into the developer's account and do anything they want with it. A further advantage of tokens is you can issue multiple tokens to the same developers. Perhaps because they have multiple apps or because they want tokens with different access levels.

(Updated to cover implications of making the connection SSL-only.)

Do you want to test for no network connection, or just a slow network connection? If the former, you can go to Settings > Wireless & networks > Airplane mode and turn Airplane mode on. That will let you test network unavailability on an actual device.

The toggle tells Bootstrap what to do and the target tells Bootstrap which element is going to open. So whenever a link like that is clicked, a modal with an id of “basicModal” will appear.

@jonrsharpe has an excellent explanation of what's going on. I thought I'd just show the difference in time when running each of the 3 options 10,000,000 times (enough for a slight difference to show).

Code used:

def a(x):
    if x != 'val':
        pass


def b(x):
    if not x == 'val':
        pass


def c(x):
    if x == 'val':
        pass
    else:
        pass


x = 1
for i in range(10000000):
    a(x)
    b(x)
    c(x)

And the cProfile profiler results:

So we can see that there is a very minute difference of ~0.7% between if not x == 'val': and if x != 'val':. Of these, if x != 'val': is the fastest.

However, most surprisingly, we can see that

if x == 'val':
        pass
    else:

is in fact the fastest, and beats if x != 'val': by ~0.3%. This isn't very readable, but I guess if you wanted a negligible performance improvement, one could go down this route.

int i, x;

i = 2;
x = ++i;
// now i = 3, x = 3

i = 2;
x = i++; 
// now i = 3, x = 2

'Post' means after - that is, the increment is done after the variable is read. 'Pre' means before - so the variable value is incremented first, then used in the expression.

To fix that error on OS X, I restarted and stopped the service: $ brew services restart mongodb $ brew services stop mongodb

Then I ran mongod --config /usr/local/etc/mongod.conf, and the problem was gone.

The error seemed to arise after upgrading the mongodb homebrew package.

Try this instead in the end:

exec (@query)

If you do not have the brackets, SQL Server assumes the value of the variable to be a stored procedure name.

OR

EXECUTE sp_executesql @query

And it should not be because of FULL JOIN.
But I hope you have already created the temp tables: #TrafficFinal, #TrafficFinal2, #TrafficFinal3 before this.

Please note that there are performance considerations between using EXEC and sp_executesql. Because sp_executesql uses forced statement caching like an sp.
More details here.

On another note, is there a reason why you are using dynamic sql for this case, when you can use the query as is, considering you are not doing any query manipulations and executing it the way it is?

Sure, the syntax is exactly the same as C - NewObj* pNew = (NewObj*)oldObj;

In this situation you may wish to consider supplying this list as a parameter to the constructor, something like:

// SelectionListViewController
-(id) initWith:(SomeListClass*)anItemList
{
  self = [super init];

  if ( self ) {
    [self setList: anItemList];
  }

  return self;
}

Then use it like this:

myEditController = [[SelectionListViewController alloc] initWith: listOfItems];

I was using http in angular 5 that was a problem. Using Httpclient resolved the issue.

/\{([^}]+)\}/

/        - delimiter
\{       - opening literal brace escaped because it is a special character used for quantifiers eg {2,3}
(        - start capturing
[^}]     - character class consisting of
    ^    - not
    }    - a closing brace (no escaping necessary because special characters in a character class are different)
+        - one or more of the character class
)        - end capturing
\}       - the closing literal brace
/        - delimiter

Use the code

x = seq(0,100,5) #this means (starting number, ending number, interval)

the output will be

An algorithm is a self-contained step-by-step set of operations to be performed 4, typically interpreted as a finite sequence of (computer or human) instructions to determine a solution to a problem such as: is there a path from A to B, or what is the smallest path between A and B. In the latter case, you could also be satisfied with a 'reasonably close' alternative solution.

There are certain categories of algorithms, of which the heuristic algorithm is one. Depending on the (proven) properties of the algorithm in this case, it falls into one of these three categories (note 1):

• Exact: the solution is proven to be an optimal (or exact solution) to the input problem
• Approximation: the deviation of the solution value is proven to be never further away from the optimal value than some pre-defined bound (for example, never more than 50% larger than the optimal value)
• Heuristic: the algorithm has not been proven to be optimal, nor within a pre-defined bound of the optimal solution

Notice that an approximation algorithm is also a heuristic, but with the stronger property that there is a proven bound to the solution (value) it outputs.

For some problems, noone has ever found an 'efficient' algorithm to compute the optimal solutions (note 2). One of those problems is the well-known Traveling Salesman Problem. Christophides' algorithm for the Traveling Salesman Problem, for example, used to be called a heuristic, as it was not proven that it was within 50% of the optimal solution. Since it has been proven, however, Christophides' algorithm is more accurately referred to as an approximation algorithm.

Due to restrictions on what computers can do, it is not always possible to efficiently find the best solution possible. If there is enough structure in a problem, there may be an efficient way to traverse the solution space, even though the solution space is huge (i.e. in the shortest path problem).

Heuristics are typically applied to improve the running time of algorithms, by adding 'expert information' or 'educated guesses' to guide the search direction. In practice, a heuristic may also be a sub-routine for an optimal algorithm, to determine where to look first.

(note 1): Additionally, algorithms are characterised by whether they include random or non-deterministic elements. An algorithm that always executes the same way and produces the same answer, is called deterministic.

(note 2): This is called the P vs NP problem, and problems that are classified as NP-complete and NP-hard are unlikely to have an 'efficient' algorithm. Note; as @Kriss mentioned in the comments, there are even 'worse' types of problems, which may need exponential time or space to compute.

There are several answers that answer part of the question. I deemed them less complete and not accurate enough, and decided not to edit the accepted answer made by @Kriss

it's late for this answer but i think maybe still can help, i try the both methods above, using two where conditions and the method with the array, none of those work for me i did several test and the condition was never getting executed, so i did a workaround, here is my code:

public function validateLogin($email, $password){
        $password = md5($password);
        $this->db->select("userID,email,password");
        $query = $this->db->get_where("users", array("email" => $email));
        $p = $query->row_array();

        if($query->num_rows() == 1 && $password == $p['password']){  
            return $query->row();
        }

    }

So to start with some kind of answer : ) - You can't

I am not an expert, but as far as I understand DataFrames, they are not equal to rdd and DataFrame has no such thing as Partitioner.

Generally DataFrame's idea is to provide another level of abstraction that handles such problems itself. The queries on DataFrame are translated into logical plan that is further translated to operations on RDDs. The partitioning you suggested will probably be applied automatically or at least should be.

If you don't trust SparkSQL that it will provide some kind of optimal job, you can always transform DataFrame to RDD[Row] as suggested in of the comments.

It looks like request_uri is deprecated in Ruby on Rails 3.

Using #request_uri is deprecated. Use fullpath instead.

You can also calculate correlations for all variables but exclude selected ones, for example:

mtcars <- data.frame(mtcars)
# here we exclude gear and carb variables
cors <- cor(subset(mtcars, select = c(-gear,-carb)))

Also, to calculate correlation between each variable and one column you can use sapply()

# sapply effectively calls the corelation function for each column of mtcars and mtcars$mpg
cors2 <- sapply(mtcars, cor, y=mtcars$mpg)

You can do this using a group by:

select id, addressCode
from t
group by id, addressCode
having min(address) <> max(address)

Another way of writing this may seem clearer, but does not perform as well:

select id, addressCode
from t
group by id, addressCode
having count(distinct address) > 1

First, you should place an UIButton and then either you can add a background image for this button, or you need to place an UIImageView over the button.

Or:

You can add the tap gesture to a UIImageView so that get the click action when tap on the UIImageView.

The actual information represented by a boolean value in Java is one bit: 1 for true, 0 for false. However, the actual size of a boolean variable in memory is not precisely defined by the Java specification. See Primitive Data Types in Java.

The boolean data type has only two possible values: true and false. Use this data type for simple flags that track true/false conditions. This data type represents one bit of information, but its "size" isn't something that's precisely defined.

Non-iteratable solution

Main function:

var keyByValue = function(value) {

    var kArray = Object.keys(greetings);        // Creating array of keys
    var vArray = Object.values(greetings);      // Creating array of values
    var vIndex = vArray.indexOf(value);         // Finding value index 

    return kArray[vIndex];                      // Returning key by value index
}

Object with keys and values:

var greetings = {
    english   : "hello",
    ukranian  : "??????"
};

Test:

keyByValue("??????");
// => "ukranian"

And the more complex query if you need to search in a several groups:

(&(objectCategory=user)(|(memberOf=CN=GroupOne,OU=Security Groups,OU=Groups,DC=example,DC=com)(memberOf=CN=GroupTwo,OU=Security Groups,OU=Groups,DC=example,DC=com)(memberOf=CN=GroupThree,OU=Security Groups,OU=Groups,DC=example,DC=com)))

The same example with recursion:

(&(objectCategory=user)(|(memberOf:1.2.840.113556.1.4.1941:=CN=GroupOne,OU=Security Groups,OU=Groups,DC=example,DC=com)(memberOf:1.2.840.113556.1.4.1941:=CN=GroupTwo,OU=Security Groups,OU=Groups,DC=example,DC=com)(memberOf:1.2.840.113556.1.4.1941:=CN=GroupThree,OU=Security Groups,OU=Groups,DC=example,DC=com)))

I set up finally using microweber/screen as proposed by @boksiora.
Initially when trying the mentioned link here what I got:

Please download this script from here https://github.com/microweber/screen

I'm on Linux. So if you want to run it, you may adjust my step follow to your environment.
Here are the step I did on my shell on DOCUMENT_ROOT folder:

$ sudo wget https://github.com/microweber/screen/archive/master.zip
$ sudo unzip master.zip
$ sudo mv screen-master screen
$ sudo chmod +x screen/bin/phantomjs
$ sudo yum install fontconfig
$ sudo yum install freetype*
$ cd screen
$ sudo curl -sS https://getcomposer.org/installer | php
$ sudo php composer.phar update
$ cd ..
$ sudo chown -R apache screen
$ sudo chgrp -R www screen
$ sudo service httpd restart

Point your browser to screen/demo/shot.php?url=google.com. When you see the screenshot, you are done. Discussion for more advance setting is available here and here.

Use JSON.stringify() to wrap your json

var parameter = JSON.stringify({type:"user", username:user_email, password:user_password});
    $http.post(url, parameter).
    success(function(data, status, headers, config) {
        // this callback will be called asynchronously
        // when the response is available
        console.log(data);
      }).
      error(function(data, status, headers, config) {
        // called asynchronously if an error occurs
        // or server returns response with an error status.
      });

Here is something else I found:

1. After I have the "prefs" URL Scheme defined, "prefs:root=Safari&path=ContentBlockers" is working on Simulator (iOS 9.1 English), but not working on Simulator (Simplified Chinese). It just jump to Safari, but not Content Blockers. If your app is international, be careful.
   Update: Don't know why, now I can't jump into ContentBlockers anymore, the same code, the same version, doesn't work now. :(

2. On real devcies (mine is iPhone 6S & iPad mini 2), "Safari" should be "SAFARI", "Safari" not working on real device, "SAFARI" now working on simulator:

   #if arch(i386) || arch(x86_64)
       // Simulator
       let url = NSURL(string: "prefs:root=Safari")!
   #else
       // Device
       let url = NSURL(string: "prefs:root=SAFARI")!
   #endif
   
   if UIApplication.sharedApplication().canOpenURL(url) {
       UIApplication.sharedApplication().openURL(url)
   }
   

3. So far, did not find any differences between iPhone and iPad.

validator package:

There seems to be a nice package by Yonatan Matalon called UrlUtil. Quoting its API:

isValidWebPageAddress(java.lang.String address, boolean validateSyntax, 
                      boolean validateExistance) 
Checks if the given address is a valid web page address.

Sun's approach - check the network address

Sun's Java site offers connect attempt as a solution for validating URLs.

Other regex code snippets:

There are regex validation attempts at Oracle's site and weberdev.com.

If all of the data in a row (for all the columns) would never reasonably take 8000 or fewer characters then the design at the data layer should enforce this.

The database engine is much more efficient keeping everything out of blob storage. The smaller you can restrict a row the better. The more rows you can cram in a page the better. The database just performs better when it has to access fewer pages.

You could use https://github.com/flew-software/trash-dump you can create file that is any size and with random data

heres a command you can run after installing trash-dump (creates a 1GB file)

$ trash-dump --filename="huge" --seed=1232 --noBytes=1000000000

BTW I created it

Loads of answers here, but haven't seen the one I use:

input[type="text"]:read-only { color: blue; }

Note the dash in the pseudo selector. If the input is readonly="false" it'll catch that too since this selector catches the presence of readonly regardless of the value. Technically false is invalid according to specs, but the internet is not a perfect world. If you need to cover that case, you can do this:

input[type="text"]:read-only:not([read-only="false"]) { color: blue; }

textarea works the same way:

textarea:read-only:not([read-only="false"]) { color: blue; }

Keep in mind that html now supports not only type="text", but a slew of other textual types such a number, tel, email, date, time, url, etc. Each would need to be added to the selector.

you can try this.

    $('#id').off().on('click', function() {
        // function body
    });
    $('.class').off().on('click', function() {
        // function body
    });

The modern approach is to move away from VBA for important code, and write a .NET managed Add-In using c# or vb.net, there are a lot of resources for this on the www, and you could use the Express version of MS Visual Studio

You can add a form onsubmit handler, something like:

<form onsubmit="return validate();">

</form>


<script>function validate() {
 // check if input is bigger than 3
 var value = document.getElementById('titleeee').value;
 if (value.length < 3) {
   return false; // keep form from submitting
 }

 // else form is good let it submit, of course you will 
 // probably want to alert the user WHAT went wrong.

 return true;
}</script>

You have to pass the arguments in the terminal in order to store them in 'argv'. This variable holds the arguments you pass to your Python script when you run it. It later unpacks the arguments and store them in different variables you specify in the program e.g.

script, first, second = argv
print "Your file is:", script
print "Your first entry is:", first
print "Your second entry is:" second

Then in your command line you have to run your code like this,

$python ex14.py Hamburger Pizza

Your output will look like this:

Your file is: ex14.py
Your first entry is: Hamburger
Your second entry is: Pizza

Try setting Javascript value as in document.getElementByName('hdntxtbxTaksit').value = '0';

To sort by second field only (thus where second fields match, those lines with matches remain in the order they are in the original without sorting on other fields) :

sort -k 2,2 -s orig_file > sorted_file

Use auto margins.

div {
   margin-left: auto;
   margin-right: auto;
   width: NNNpx;

   /* NOTE: Only works for non-floated block elements */
   display: block;
   float: none;
}

Whenever I have a class that contains a nested class that is of any significant size/complexity, I mark the class as partial and put the nested class in a separate file. I name the file containing the nested class using the rule: [class name].[nested class name].cs.

The following MSDN blog explains using partial classes with nested classes for maintainability: http://blogs.msdn.com/b/marcelolr/archive/2009/04/13/using-partial-classes-with-nested-classes-for-maintainability.aspx

I thought Activity was deprecated

No.

So for API Level 22 (with a minimum support for API Level 15 or 16), what exactly should I use both to host the components, and for the components themselves? Are there uses for all of these, or should I be using one or two almost exclusively?

Activity is the baseline. Every activity inherits from Activity, directly or indirectly.

FragmentActivity is for use with the backport of fragments found in the support-v4 and support-v13 libraries. The native implementation of fragments was added in API Level 11, which is lower than your proposed minSdkVersion values. The only reason why you would need to consider FragmentActivity specifically is if you want to use nested fragments (a fragment holding another fragment), as that was not supported in native fragments until API Level 17.

AppCompatActivity is from the appcompat-v7 library. Principally, this offers a backport of the action bar. Since the native action bar was added in API Level 11, you do not need AppCompatActivity for that. However, current versions of appcompat-v7 also add a limited backport of the Material Design aesthetic, in terms of the action bar and various widgets. There are pros and cons of using appcompat-v7, well beyond the scope of this specific Stack Overflow answer.

ActionBarActivity is the old name of the base activity from appcompat-v7. For various reasons, they wanted to change the name. Unless some third-party library you are using insists upon an ActionBarActivity, you should prefer AppCompatActivity over ActionBarActivity.

So, given your minSdkVersion in the 15-16 range:

• If you want the backported Material Design look, use AppCompatActivity

• If not, but you want nested fragments, use FragmentActivity

• If not, use Activity

Just adding from comment as note: AppCompatActivity extends FragmentActivity, so anyone who needs to use features of FragmentActivity can use AppCompatActivity.

When neither sudo nor apt-get is available in container, you can also jump into running container as root user using command

docker exec -u root -t -i container_id /bin/bash

var partsOfStr = str.split(',');

split()

It is common practice in C++. This is because in C++ you can't have same name for the member function and member variable, and getter functions are often named without "get" prefix.

class Person
{
   public:
      std::string name() const;

   private:
      std::string name; // This would lead to a compilation error.
      std::string m_name; // OK.
};

main.cpp:9:19: error: duplicate member 'name'
      std::string name;
                  ^
main.cpp:6:19: note: previous declaration is here
      std::string name() const;
                  ^
1 error generated.

"m_" states for the "member". Prefix "_" is also common.

You shouldn't use it in programming languages that solve this problem by using different conventions/grammar.

If you're working with an asp.net application and you want to locate assemblies when using the debugger, they are usually put into some temp directory. I wrote the this method to help with that scenario.

private string[] GetAssembly(string[] assemblyNames)
{
    string [] locations = new string[assemblyNames.Length];


    for (int loop = 0; loop <= assemblyNames.Length - 1; loop++)       
    {
         locations[loop] = AppDomain.CurrentDomain.GetAssemblies().Where(a => !a.IsDynamic && a.ManifestModule.Name == assemblyNames[loop]).Select(a => a.Location).FirstOrDefault();
    }
    return locations;
}

If you can't change the source code, or redeploy, but you can examine the running processes on the computer use Process Explorer. I written a detailed description here.

It will list all executing dlls on the system, you may need to determine the process id of your running application, but that is usually not too difficult.

I've written a full description of how do this for a dll inside IIS - http://nodogmablog.bryanhogan.net/2016/09/locating-and-checking-an-executing-dll-on-a-running-web-server/

If you still get

TCPDF ERROR: Unable to create output file: myfile.pdf

you can avoid TCPDF's file saving logic by putting PDF data to a variable and saving this string to a file:

$pdf_string = $pdf->Output('pseudo.pdf', 'S');
file_put_contents('./mydir/myfile.pdf', $pdf_string);

 X <- data.frame(Variable1=c(11,14,12,15),Variable2=c(2,3,1,4))
> X
  Variable1 Variable2
1        11         2
2        14         3
3        12         1
4        15         4
> X[X$Variable1!=11 & X$Variable1!=12, ]
  Variable1 Variable2
2        14         3
4        15         4
> X[ ! X$Variable1 %in% c(11,12), ]
  Variable1 Variable2
2        14         3
4        15         4

You can functionalize this however you like.

While exec(open("filename").read()) is often given as an alternative to execfile("filename"), it misses important details that execfile supported.

The following function for Python3.x is as close as I could get to having the same behavior as executing a file directly. That matches running python /path/to/somefile.py.

def execfile(filepath, globals=None, locals=None):
    if globals is None:
        globals = {}
    globals.update({
        "__file__": filepath,
        "__name__": "__main__",
    })
    with open(filepath, 'rb') as file:
        exec(compile(file.read(), filepath, 'exec'), globals, locals)

# execute the file
execfile("/path/to/somefile.py")

Notes:

• Uses binary reading to avoid encoding issues
• Guaranteed to close the file (Python3.x warns about this)
• Defines __main__, some scripts depend on this to check if they are loading as a module or not for eg. if __name__ == "__main__"
• Setting __file__ is nicer for exception messages and some scripts use __file__ to get the paths of other files relative to them.

• Takes optional globals & locals arguments, modifying them in-place as execfile does - so you can access any variables defined by reading back the variables after running.

• Unlike Python2's execfile this does not modify the current namespace by default. For that you have to explicitly pass in globals() & locals().

Regardless of your situation, heres a working demo that creates markers on the map based on an array of addresses.

http://jsfiddle.net/P2QhE/

Javascript code embedded aswell:

$(document).ready(function () {
    var map;
    var elevator;
    var myOptions = {
        zoom: 1,
        center: new google.maps.LatLng(0, 0),
        mapTypeId: 'terrain'
    };
    map = new google.maps.Map($('#map_canvas')[0], myOptions);

    var addresses = ['Norway', 'Africa', 'Asia','North America','South America'];

    for (var x = 0; x < addresses.length; x++) {
        $.getJSON('http://maps.googleapis.com/maps/api/geocode/json?address='+addresses[x]+'&sensor=false', null, function (data) {
            var p = data.results[0].geometry.location
            var latlng = new google.maps.LatLng(p.lat, p.lng);
            new google.maps.Marker({
                position: latlng,
                map: map
            });

        });
    }

}); 

Alternatively, you could invert the image using the bitwise_not function of OpenCV:

imagem = cv2.bitwise_not(imagem)

I liked this example.

Try using absolute positioning, rather than relative positioning

this should get you close - you can adjust by tweaking margins or top/left positions

#play_button {
    position:absolute;
    transition: .5s ease;
    top: 50%;
    left: 50%;
}

using Dollar should be quite simple:

List<Integer> list = $(5).toList(); // the list 0, 1, 2, 3, 4  
int[] array = $($(list).toArray()).toIntArray();

I'm planning to improve the DSL in order to remove the intermediate toArray() call

I did this to remove the decimal places from the double value

new DecimalFormat("#").format(100.0);

The output of the above is

100

On Error Resume Next means that On Error, It will resume to the next line to resume.

e.g. if you try the Try block, That will stop the script if a error occurred

Check what RAND_MAX is on your system -- I'm guessing it is only 16 bits, and your range is too big for it.

Beyond that see this discussion on: Generating Random Integers within a Desired Range and the notes on using (or not) the C rand() function.

I was able to quickly fix it by going into Design View of the Form and putting [] around any field names that had spaces. I am now able to use the built in filters without the annoying popup about syntax problems.

unnest can be used as well. It expands array to a set of rows and then simply checking a value exists or not is as simple as using IN or NOT IN.

e.g.

1. id => uuid

2. exception_list_ids => uuid[]

select * from table where id NOT IN (select unnest(exception_list_ids) from table2)

Or you can use one SQL-command instead of create and call stored procedure

INSERT INTO [order_cart](orId,caId)
OUTPUT inserted.*
SELECT
   (SELECT MAX(orId) FROM [order]) as orId,
   (SELECT MAX(caId) FROM [cart]) as caId;

I will put here some real case examples and scenarios when to use one or another, it might be of help for somebody else:

HashMap

When you have to use cache in your application. Redis and membase are some type of extended HashMap. (Doesn't matter the order of the elements, you need quick ( O(1) ) read access (a value), using a key).

LinkedList

When the order is important (they are ordered as they were added to the LinkedList), the number of elements are unknown (don't waste memory allocation) and you require quick insertion time ( O(1) ). A list of to-do items that can be listed sequentially as they are added is a good example.

Disclaimer: I love python. It's multi-line strings are only one reason.

But I also do VB.Net, so here's my short-cut for more readable long strings.

  Dim lines As String() = {
    "Line 1",
    "Line 2",
    "Line 3"
  }
  Dim s As String = Join(lines, vbCrLf)

After not finding anything to get around "Object must implement IConvertible" exception when using Zyphrax's answer (except for implementing the interface).. I tried something a little bit unconventional and worked for my situation.

Using the Newtonsoft.Json nuget package...

var castedObject = JsonConvert.DeserializeObject(JsonConvert.SerializeObject(myObject), myType);

This builds on Jon Willis's answer that relies upon assert, which only gets executed in Debug compilations:

func Log(_ str: String) { 
    assert(DebugLog(str)) 
}
func DebugLog(_ str: String) -> Bool { 
    print(str) 
    return true
}

My use case is for logging print statements. Here is a benchmark for Release version on iPhone X:

let iterations = 100_000_000
let time1 = CFAbsoluteTimeGetCurrent()
for i in 0 ..< iterations {
    Log ("? unarchiveArray:\(fileName) memoryTime:\(memoryTime) count:\(array.count)")
}
var time2 = CFAbsoluteTimeGetCurrent()
print ("Log: \(time2-time1)" )

prints:

Log: 0.0

Looks like Swift 4 completely eliminates the function call.

Another way could be to use json.dumps(X, sort_keys=True) option:

import json
a, b = json.dumps(a, sort_keys=True), json.dumps(b, sort_keys=True)
a == b # a normal string comparison

This works for nested dictionaries and lists.

If you're seeing these in a source be aware that it may be someone attempting to fingerprint text documents to reveal who is leaking information. It also may be an attempt to bypass a spam filter by making the same looking information different on a byte-by-byte level.

See my article on mitigating fingerprinting if you're interested in learning more.

public class DayFlipper extends ViewPager {

private Flipperadapter adapter;
public class FlipperAdapter extends PagerAdapter {

    @Override
    public int getCount() {
        return DayFlipper.DAY_HISTORY;
    }

    @Override
    public void startUpdate(View container) {
    }

    @Override
    public Object instantiateItem(View container, int position) {
        Log.d(TAG, "instantiateItem(): " + position);

        Date d = DateHelper.getBot();
        for (int i = 0; i < position; i++) {
            d = DateHelper.getTomorrow(d);
        }

        d = DateHelper.normalize(d);

        CubbiesView cv = new CubbiesView(mContext);
        cv.setLifeDate(d);
        ((ViewPager) container).addView(cv, 0);
        // add map
        cv.setCubbieMap(mMap);
        cv.initEntries(d);
adpter = FlipperAdapter.this;
        return cv;
    }

    @Override
    public void destroyItem(View container, int position, Object object) {
        ((ViewPager) container).removeView((CubbiesView) object);

    @Override
    public void finishUpdate(View container) {

    }

    @Override
    public boolean isViewFromObject(View view, Object object) {
        return view == ((CubbiesView) object);
    }

    @Override
    public Parcelable saveState() {
        return null;
    }

try this.

Based on few of the comments above, difference is I just used lambda

Executors.newFixedThreadPool(10, r -> new Thread(r, "my-threads-%d"))

jQuery:

$("#y").load("x.html");

Use Linq's Union:

using System.Linq;
var l1 = new List<int>() { 1,2,3,4,5 };
var l2 = new List<int>() { 3,5,6,7,8 };
var l3 = l1.Union(l2).ToList();

In case someone lands here after making the same mistake I did:

1. Switched to plugin="mysql_native_password" temporarily. Performed my tasks.
2. Attempted to switch back to the "auth_socket" plugin, but incorrectly referenced it as plugin="auth_socket" which resulted in mysql "ERROR 1524 (HY000): Plugin 'auth_socket' is not loaded"
3. Lacking a way to login to fix this mistake, I was forced to have to stop mysql and use mysql_safe to bypass authentication in order to switch to the appropriate plugin plugin="unix_socket"

Hopefully this saves someone some time if they receive the original poster's error message, but the true cause was flubbing the plugin name, not actually lacking the existence of the "auth_socket" plugin itself, which according to the MariaDB documentation:

In MariaDB 10.4.3 and later, the unix_socket authentication plugin is installed by default, and it is used by the 'root'@'localhost' user account by default.

First the facts, neither is better. As you already mentioned, Tomcat provides a servlet container that supports the Servlet specification (Tomcat 7 supports Servlet 3.0). JBoss AS, a 'complete' application server supports Java EE 6 (including Servlet 3.0) in its current version.

Tomcat is fairly lightweight and in case you need certain Java EE features beyond the Servlet API, you can easily enhance Tomcat by providing the required libraries as part of your application. For example, if you need JPA features you can include Hibernate or OpenEJB and JPA works nearly out of the box.

How to decide whether to use Tomcat or a full stack Java EE application server:

When starting your project you should have an idea what it requires. If you're in a large enterprise environment JBoss (or any other Java EE server) might be the right choice as it provides built-in support for e.g:

1. JMS messaging for asynchronous integration
2. Web Services engine (JAX-WS and/or JAX-RS)
3. Management capabilities like JMX and a scripted administration interface
4. Advanced security, e.g. out-of-the-box integration with 3rd party directories
5. EAR file instead of "only" WAR file support
6. all the other "great" Java EE features I can't remember :-)

In my opinion Tomcat is a very good fit if it comes to web centric, user facing applications. If backend integration comes into play, a Java EE application server should be (at least) considered. Last but not least, migrating a WAR developed for Tomcat to JBoss should be a 1 day excercise.

Second, you should also take the usage inside your environment into account. In case your organization already runs say 1,000 JBoss instances, you might always go with that regardless of your concrete requirements (consider aspects like cost for operations or upskilling). Of course, this applies vice versa.

my 2 cent

COUNT is part of pig see the manual

LOGS= LOAD 'log';
LOGS_GROUP= GROUP LOGS ALL;
LOG_COUNT = FOREACH LOGS_GROUP GENERATE COUNT(LOGS);

Assuming you want to simply lift the 32bits from one type and dump them as-is into the other type:

uint asUint = unchecked((uint)myInt);
int asInt = unchecked((int)myUint);

The destination type will blindly pick the 32 bits and reinterpret them.

Conversely if you're more interested in keeping the decimal/numerical values within the range of the destination type itself:

uint asUint = checked((uint)myInt);
int asInt = checked((int)myUint);

In this case, you'll get overflow exceptions if:

• casting a negative int (eg: -1) to an uint
• casting a positive uint between 2,147,483,648 and 4,294,967,295 to an int

In our case, we wanted the unchecked solution to preserve the 32bits as-is, so here are some examples:

Examples

int => uint

asInt..: -0000000001 (FF-FF-FF-FF)
------------------------------

Code

int[] testInts = { 0, 1, -1, int.MaxValue, int.MinValue };
uint[] testUints = { uint.MinValue, 1, uint.MaxValue / 2, uint.MaxValue };

foreach (var Int in testInts)
{
    uint asUint = unchecked((uint)Int);
    Console.WriteLine("int....: {0:D10} ({1})", Int, BitConverter.ToString(BitConverter.GetBytes(Int)));
    Console.WriteLine("asUint.: {0:D10} ({1})", asUint, BitConverter.ToString(BitConverter.GetBytes(asUint)));
    Console.WriteLine(new string('-',30));
}
Console.WriteLine(new string('=', 30));
foreach (var Uint in testUints)
{
    int asInt = unchecked((int)Uint);
    Console.WriteLine("uint...: {0:D10} ({1})", Uint, BitConverter.ToString(BitConverter.GetBytes(Uint)));
    Console.WriteLine("asInt..: {0:D10} ({1})", asInt, BitConverter.ToString(BitConverter.GetBytes(asInt)));
    Console.WriteLine(new string('-', 30));
}  

Because I haven't seen it here yet... When you vagrant ssh into the box, I realized it actually tells you the ip addresses of the interfaces. You can get it there. For example.

and as you can see, IP address for enp0s8: 192.168.33.10

<meta charset="utf-8"> was introduced with/for HTML5.

As mentioned in the documentation, both are valid. However, <meta charset="utf-8"> is only for HTML5 (and easier to type/remember).

In due time, the old style is bound to become deprecated in the near future. I'd stick to the new <meta charset="utf-8">.

There's only one way, but up. In tech's case, that's phasing out the old (really, REALLY fast)

It would be easier to make suggestions if you provided example code and data.

Accessing the dictionary is unlikely to be a problem as that operation is O(1) on average, and O(N) amortized worst case. It's possible that the built-in hashing functions are experiencing collisions for your data. If you're having problems with has the built-in hashing function, you can provide your own.

Python's dictionary implementation reduces the average complexity of dictionary lookups to O(1) by requiring that key objects provide a "hash" function. Such a hash function takes the information in a key object and uses it to produce an integer, called a hash value. This hash value is then used to determine which "bucket" this (key, value) pair should be placed into.

You can overwrite the __hash__ method in your class to implement a custom hash function like this:

def __hash__(self):    
    return hash(str(self))

Depending on what your data actually looks like, you might be able to come up with a faster hash function that has fewer collisions than the standard function. However, this is unlikely. See the Python Wiki page on Dictionary Keys for more information.

Any !important can be overridden by another !important, the normal CSS precedence rules still apply.

Example:

#an-element{
    background: #F00 !important;
}
#an-element{
    background: #0F0 !important; //Makes #an-element green
}

Then you could add a style attribute (using JavaScript/jQuery) to override the CSS

$(function () {  
    $("#an-element").attr('style', 'background: #00F !important;');
    //Makes #an-element blue
});

See the result here

Use break.

Unrelated to your question, I see in your code the line:

Violated = !(name.firstname == null) ? false : true;

In this line, you take a boolean value (name.firstname == null). Then, you apply the ! operator to it. Then, if the value is true, you set Violated to false; otherwise to true. So basically, Violated is set to the same value as the original expression (name.firstname == null). Why not use that, as in:

Violated = (name.firstname == null);

You might also want to consider the Android specific TextUtils.split() method.

The difference between TextUtils.split() and String.split() is documented with TextUtils.split():

String.split() returns [''] when the string to be split is empty. This returns []. This does not remove any empty strings from the result.

I find this a more natural behavior. In essence TextUtils.split() is just a thin wrapper for String.split(), dealing specifically with the empty-string case. The code for the method is actually quite simple.

You close the second Scanner which closes the underlying InputStream, therefore the first Scanner can no longer read from the same InputStream and a NoSuchElementException results.

The solution: For console apps, use a single Scanner to read from System.in.

Aside: As stated already, be aware that Scanner#nextInt does not consume newline characters. Ensure that these are consumed before attempting to call nextLine again by using Scanner#newLine().

See: Do not create multiple buffered wrappers on a single InputStream

Check out if you are missing some import.

try this : here select is your select element

let select = document.getElementsByClassName('lstSelected')[0],
    options = select.options,
    len = options.length,
    data='',
    i=0;
while (i<len){
    if (options[i].selected)
        data+= "&" + select.name + '=' + options[i].value;
    i++;
}
return data;

Data is in the form of query string i.e.name=value&name=anotherValue

Something that I tried and work for me is simply you create a new virtual machine and you use the existing virtual hard disk file and everything is like you left it.

"Validation injection without submit looping":

I just want to check reCaptcha and some other stuff before HTML5 validation, so I did something like that (the validation function returns true or false):

$(document).ready(function(){
   var application_form = $('form#application-form');

   application_form.on('submit',function(e){

        if(application_form_extra_validation()===true){
           return true;
        }

        e.preventDefault();

   });
});

This can also occur when using the wrong import (for example when using autoimport). let's take the MatTimePickerModule as an example. This will give an error message that is similar to the one described in the question:

import { NgxMatTimepickerModule } from '@angular-material-components/datetime-picker/lib/timepicker.module';

This should instead be

import { NgxMatTimepickerModule } from '@angular-material-components/datetime-picker';

How about this?

=IF(ISERROR(MATCH(A1,B:B, 0)), "No Match", INDIRECT(ADDRESS(MATCH(A1,B:B, 0), 3)))

The "3" at the end means for column C.

You don't need an initializer, unless you're dynamically loading a different image each time. I think doing as much as possible in fxml is more organized. Here is an fxml file that will do what you need.

                pickOnBounds="true"
                preserveRatio="true"
            >
            <image>
                <Image
                    url="src/Box13.jpg"
                    backgroundLoading="true"
                    />
            </image>
        </ImageView>
    </children>
</AnchorPane>

Specifying the backgroundLoading property in the Image tag is optional, it defaults to false. It's best to set backgroundLoading true when it takes a moment or longer to load the image, that way a placeholder will be used until the image loads, and the program wont freeze while loading.

I had met a similar problem, after i add a scope property of servlet dependency in pom.xml

 <dependency>
  <groupId>javax.servlet</groupId>
  <artifactId>javax.servlet-api</artifactId>
  <version>3.0.1</version>
    <scope>provided</scope>
</dependency>

Then it was ok . maybe that will help you.

If you use Kotlin, you can use extension functions as such, for example:

fun <T> LongSparseArray<T>.valuesIterator(): Iterator<T> {
    val nSize = this.size()
    return object : Iterator<T> {
        var i = 0
        override fun hasNext(): Boolean = i < nSize
        override fun next(): T = valueAt(i++)
    }
}

fun <T> LongSparseArray<T>.keysIterator(): Iterator<Long> {
    val nSize = this.size()
    return object : Iterator<Long> {
        var i = 0
        override fun hasNext(): Boolean = i < nSize
        override fun next(): Long = keyAt(i++)
    }
}

fun <T> LongSparseArray<T>.entriesIterator(): Iterator<Pair<Long, T>> {
    val nSize = this.size()
    return object : Iterator<Pair<Long, T>> {
        var i = 0
        override fun hasNext(): Boolean = i < nSize
        override fun next() = Pair(keyAt(i), valueAt(i++))
    }
}

You can also convert to a list, if you wish. Example:

sparseArray.keysIterator().asSequence().toList()

I think it might even be safe to delete items using remove on the LongSparseArray itself (not on the iterator), as it is in ascending order.

EDIT: Seems there is even an easier way, by using collection-ktx (example here) . It's implemented in a very similar way to what I wrote, actally.

Gradle requires this:

implementation 'androidx.core:core-ktx:#'
implementation 'androidx.collection:collection-ktx:#'

Here's the usage for LongSparseArray :

    val sparse= LongSparseArray<String>()
    for (key in sparse.keyIterator()) {
    }
    for (value in sparse.valueIterator()) {
    }
    sparse.forEach { key, value -> 
    }

And for those that use Java, you can use LongSparseArrayKt.keyIterator , LongSparseArrayKt.valueIterator and LongSparseArrayKt.forEach , for example. Same for the other cases.

Is this what you're after?

I got the same error {AttributeError: 'bytes' object has no attribute 'read'} in python3. This worked for me later without using json:

from urllib.request import urlopen
from bs4 import BeautifulSoup

url = 'https://someurl/'
page = urlopen(url)
html = page.read()
soup = BeautifulSoup(html)
print(soup.prettify('latin-1'))

first you need to add 2 columns to datagrid. you may do it at design time. see Columns property. then add rows as much as you need.

this.dataGridView1.Rows.Add("1", "XX");

First step would be making the function object, then applying it. If you want a matrix object that has the same number of rows, you can predefine it and use the object[] form as illustrated (otherwise the returned value will be simplified to a vector):

bvnormdens <- function(x=c(0,0),mu=c(0,0), sigma=c(1,1), rho=0){
     exp(-1/(2*(1-rho^2))*(x[1]^2/sigma[1]^2+
                           x[2]^2/sigma[2]^2-
                           2*rho*x[1]*x[2]/(sigma[1]*sigma[2]))) * 
     1/(2*pi*sigma[1]*sigma[2]*sqrt(1-rho^2))
     }
 out=rbind(c(1,2),c(3,4),c(5,6));

 bvout<-matrix(NA, ncol=1, nrow=3)
 bvout[] <-apply(out, 1, bvnormdens)
 bvout
             [,1]
[1,] 1.306423e-02
[2,] 5.931153e-07
[3,] 9.033134e-15

If you wanted to use other than your default parameters then the call should include named arguments after the function:

bvout[] <-apply(out, 1, FUN=bvnormdens, mu=c(-1,1), rho=0.6)

apply() can also be used on higher dimensional arrays and the MARGIN argument can be a vector as well as a single integer.

This should work for SQL Server:

SELECT * FROM myTable
WHERE month = DATEPART(m, GETDATE()) AND
year = DATEPART(yyyy, GETDATE())

The out of memory suggestion doesn't seem like a bad lead.

What is your program doing that it gets this error?

Is it creating a great many windows or controls? Does it create them programatically as opposed to at design time? If so, do you do this in a loop? Is that loop infinite? Are you consuming staggering boatloads of memory in some other way?

What happens when you watch the memory used by your application in task manager? Does it skyrocket to the moon? Or better yet, as suggested above use process monitor to dive into the details.

It can be done in your code via WMI. I've found a tool from Microsoft that creates code for it.

The WMI Code Creator tool allows you to generate VBScript, C#, and VB .NET code that uses WMI to complete a management task such as querying for management data, executing a method from a WMI class, or receiving event notifications using WMI.

You can download it here.

This is the Solution for jQuery 3.4

<script src="./js/util.js" data-m="myParam"></script>

$(document).ready(function () {
    var m = $('script[data-m][data-m!=null]').attr('data-m');
})

You need to assign the result back to $content as preg_replace does not modify the original string.

$content = preg_replace("/<img[^>]+\>/i", "(image) ", $content);

Use Integer.toString(tmpInt) instead.

I have came across this issue few times during the development of one complex Excel VBA app. Sometimes Excel started to break VBA object quite randomly. And the only remedy was to reboot machine. After reboot, Excel usually started to act normally.

Soon I have found out that possible solution to this issue is to hit CTRL+Break once when macro is NOT running. Maybe this can help to you too.

Suppose you want to search "column" in "Table" and you want case insenstive search. The best and efficient way is as below;

//create empty JSON Object
mycolumn = {};

//check if column has valid value
if(column) {
    mycolumn.column = {$regex: new RegExp(column), $options: "i"};
}
Table.find(mycolumn);

Above code just adds your search value as RegEx and searches in with insensitve criteria set with "i" as option.

All the best.

After multiple tests, this is the best way I found :)

Set<User> test = httpService.get(url).toResponseSet(User[].class);

All you need there

public <T> Set<T> toResponseSet(Class<T[]> setType) {
    HttpEntity<?> body = new HttpEntity<>(objectBody, headers);
    ResponseEntity<T[]> response = template.exchange(url, method, body, setType);
    return Sets.newHashSet(response.getBody());
}

I just want to add something to Mark's comment. If you want to reuse array without additional allocation, just use it again and override existing values with new ones. It will work if you fill the array sequentially. In this case just remember the last initialized element and use array until this index. It is does not matter that there is some garbage in the end of the array.

There is no such thing as array constant in Go.

Quoting from the Go Language Specification: Constants:

There are boolean constants, rune constants, integer constants, floating-point constants, complex constants, and string constants. Rune, integer, floating-point, and complex constants are collectively called numeric constants.

A Constant expression (which is used to initialize a constant) may contain only constant operands and are evaluated at compile time.

The specification lists the different types of constants. Note that you can create and initialize constants with constant expressions of types having one of the allowed types as the underlying type. For example this is valid:

func main() {
    type Myint int
    const i1 Myint = 1
    const i2 = Myint(2)
    fmt.Printf("%T %v\n", i1, i1)
    fmt.Printf("%T %v\n", i2, i2)
}

Output (try it on the Go Playground):

main.Myint 1
main.Myint 2

If you need an array, it can only be a variable, but not a constant.

I recommend this great blog article about constants: Constants

Try username = root and password is blank.

Try the following:

var output = Regex.Replace(input, @"[\d-]", string.Empty);

The \d identifier simply matches any digit character.

Execute is sql*plus syntax .. try wrapping your call in begin .. end like this:

I was playing around with ways to restart a container. What I found for me was this solution:

Dockerfile:

...
ENTRYPOINT [ "/app/bootstrap.sh" ]

/app/bootstrap.sh:

#!/bin/bash
/app/startWhatEverYouActuallyWantToStart.sh &
tail -f /dev/null

Whenever I want to restart the container, I kill the process with tail -f /dev/null which I find with

kill -TERM `ps --ppid 1 | grep tail | grep -v -e grep | awk '{print $1}'`

Following that command, all the processes except for the one with PID==1 will be killed and the entrypoint, in my case bootstrap.sh will be executed (again).

That's for the part "restart" - which is not really a restart but it does what you wish, in the end. For the part with limiting restarting the container named container-test you could pass on the container name to the container in question (as the container name would otherwise not be available inside the container) and then you can decide whether to do the above kill. That would be something like this in your deployment.yaml:

    env:
    - name: YOUR_CONTAINER_NAME
      value: container-test

/app/startWhatEverYouActuallyWantToStart.sh:

#!/bin/bash
...
CONDITION_TO_RESTART=0
...
if [ "$YOUR_CONTAINER_NAME" == "container-test" -a $CONDITION_TO_RESTART -eq 1 ]; then
    kill -TERM `ps --ppid 1 | grep tail | grep -v -e grep | awk '{print $1}'`
fi

For phpMyAdmin I figured this out:

SELECT GROUP_CONCAT("ALTER TABLE ", TABLE_SCHEMA, '.', TABLE_NAME," CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;" SEPARATOR ' ') AS    OneSQLString
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_SCHEMA="yourtableschemaname"
AND TABLE_TYPE="BASE TABLE"

Just change yourtableschemaname and you're fine.

There's a simple JavaScript tri-state input field implementation at https://github.com/supernifty/tristate-checkbox

As other people have commented above, using TRUNC will prevent the use of indexes (if there was an index on TIME_CREATED). To avoid that problem, the query can be structured as

SELECT EMP_NAME, DEPT
FROM EMPLOYEE
WHERE TIME_CREATED BETWEEN TO_DATE('26/JAN/2011','dd/mon/yyyy') 
            AND TO_DATE('26/JAN/2011','dd/mon/yyyy') + INTERVAL '86399' second;

86399 being 1 second less than the number of seconds in a day.

I came across this question and thought I would clarify that the lists() method of a eloquent builder object was depreciated in Laravel 5.2 and replaced with pluck().

// <= Laravel 5.1
Word_relation::where('word_one', $word_id)->lists('word_one')->toArray();
// >= Laravel 5.2
Word_relation::where('word_one', $word_id)->pluck('word_one')->toArray();

These methods can also be called on a Collection for example

// <= Laravel 5.1
  $collection = Word_relation::where('word_one', $word_id)->get();
  $array = $collection->lists('word_one');

// >= Laravel 5.2
  $collection = Word_relation::where('word_one', $word_id)->get();
  $array = $collection->pluck('word_one');

You did not specify the database engine in question; in Oracle, an option is to use tuples like this:

SELECT * FROM table WHERE (Col, 1) IN ((123,1),(123,1),(222,1),....)

This ugly hack only works in Oracle SQL, see https://asktom.oracle.com/pls/asktom/asktom.search?tag=limit-and-conversion-very-long-in-list-where-x-in#9538075800346844400

However, a much better option is to use stored procedures and pass the values as an array.

Enable CORS on backend server or add chrome extensions https://chrome.google.com/webstore/search/CORS?utm_source=chrome-ntp-icon and make ON

To calculate the mean, loop through the list/array of numbers, keeping track of the partial sums and the length. Then return the sum/length.

double sum = 0.0;
int length = 0;

for( double number : numbers ) {
    sum += number;
    length++;
}

return sum/length;

Variance is calculated similarly. Standard deviation is simply the square root of the variance:

double stddev = Math.sqrt( variance );

For TensorFlow 2.0 and 2.1 (docs):

import tensorflow as tf
tf.config.gpu.set_per_process_memory_growth(True)

For TensorFlow 2.2+ (docs):

import tensorflow as tf
gpus = tf.config.experimental.list_physical_devices('GPU')
for gpu in gpus:
  tf.config.experimental.set_memory_growth(gpu, True)

The docs also list some more methods:

• Set environment variable TF_FORCE_GPU_ALLOW_GROWTH to true.
• Use tf.config.experimental.set_virtual_device_configuration to set a hard limit on a Virtual GPU device.

Set the following two environment variables:

NVIDIA_VISIBLE_DEVICES=$gpu_id
CUDA_VISIBLE_DEVICES=0

where gpu_id is the ID of your selected GPU, as seen in the host system's nvidia-smi (a 0-based integer) that will be made available to the guest system (e.g. to the Docker container environment).

You can verify that a different card is selected for each value of gpu_id by inspecting Bus-Id parameter in nvidia-smi run in a terminal in the guest system).

More info

This method based on NVIDIA_VISIBLE_DEVICES exposes only a single card to the system (with local ID zero), hence we also hard-code the other variable, CUDA_VISIBLE_DEVICES to 0 (mainly to prevent it from defaulting to an empty string that would indicate no GPU).

Note that the environmental variable should be set before the guest system is started (so no chances of doing it in your Jupyter Notebook's terminal), for instance using docker run -e NVIDIA_VISIBLE_DEVICES=0 or env in Kubernetes or Openshift.

If you want GPU load-balancing, make gpu_id random at each guest system start.

If setting this with python, make sure you are using strings for all environment variables, including numerical ones.

You can verify that a different card is selected for each value of gpu_id by inspecting nvidia-smi's Bus-Id parameter (in a terminal run in the guest system).

The accepted solution based on CUDA_VISIBLE_DEVICES alone does not hide other cards (different from the pinned one), and thus causes access errors if you try to use them in your GPU-enabled python packages. With this solution, other cards are not visible to the guest system, but other users still can access them and share their computing power on an equal basis, just like with CPU's (verified).

This is also preferable to solutions using Kubernetes / Openshift controlers (resources.limits.nvidia.com/gpu), that would impose a lock on the allocated card, removing it from the pool of available resources (so the number of containers with GPU access could not exceed the number of physical cards).

This has been tested under CUDA 8.0, 9.0 and 10.1 in docker containers running Ubuntu 18.04 orchestrated by Openshift 3.11.

As @Travis Solution works but in some cases

var millisecondsSince1970:Int WILL CAUSE CRASH APPLICATION ,

with error

Double value cannot be converted to Int because the result would be greater than Int.max if it occurs Please update your answer with Int64

Here is Updated Answer

extension Date {
 var millisecondsSince1970:Int64 {
        return Int64((self.timeIntervalSince1970 * 1000.0).rounded()) 
        //RESOLVED CRASH HERE
    }

    init(milliseconds:Int) {
        self = Date(timeIntervalSince1970: TimeInterval(milliseconds / 1000))
    }
}

About Int definitions.

On 32-bit platforms, Int is the same size as Int32, and on 64-bit platforms, Int is the same size as Int64.

Generally, I encounter this problem in iPhone 5, which runs in 32-bit env. New devices run 64-bit env now. Their Int will be Int64.

Hope it is helpful to someone who also has same problem

#kinda like the one above but better :P

from __future__ import print_function
from time import sleep

for i in range(101):
  str1="Downloading File FooFile.txt [{}%]".format(i)
  back="\b"*len(str1)
  print(str1, end="")
  sleep(0.1)
  print(back, end="")

The existing answers (pass the data in the Intent passed to startActivity()) show the normal way to solve this problem. There is another solution that can be used in the odd case where you're creating an Activity that will be started by another app (for example, one of the edit activities in a Tasker plugin) and therefore do not control the Intent which launches the Activity.

You can create a base-class Activity that has a constructor with a parameter, then a derived class that has a default constructor which calls the base-class constructor with a value, as so:

class BaseActivity extends Activity
{
    public BaseActivity(String param)
    {
        // Do something with param
    }
}

class DerivedActivity extends BaseActivity
{
    public DerivedActivity()
    {
        super("parameter");
    }
}

If you need to generate the parameter to pass to the base-class constructor, simply replace the hard-coded value with a function call that returns the correct value to pass.

def recursive_dir_size(path):
    size = 0

    for x in os.listdir(path):
        if not os.path.isdir(os.path.join(path,x)):
            size += os.stat(os.path.join(path,x)).st_size
        else:
            size += recursive_dir_size(os.path.join(path,x))

    return size

I wrote this function which gives me accurate overall size of a directory, i tried other for loop solutions with os.walk but i don't know why the end result was always less than the actual size (on ubuntu 18 env). I must have done something wrong but who cares wrote this one works perfectly fine.

To avoid having to type additional .catch(function () {}) in your code in multiple places, you could add a decorator to the $exceptionHandler.

This is a more verbose option than the others but you only have to make the change in one place.

angular
    .module('app')
    .config(configDecorators);

configDecorators.$inject = ["$provide"];
function configDecorators($provide) {

    $provide.decorator("$exceptionHandler", exceptionHandler);

    exceptionHandler.$inject = ['$delegate', '$injector'];
    function exceptionHandler($delegate, $injector) {
        return function (exception, cause) {

            if ((exception.toString().toLowerCase()).includes("Possibly unhandled rejection".toLowerCase())) {
                console.log(exception); /* optional to log the "Possibly unhandled rejection" */
                return;
            }
            $delegate(exception, cause);
        };
    }
};

• width: auto; will try as hard as possible to keep an element the same width as its parent container when additional space is added from margins, padding, or borders.

• width: 100%; will make the element as wide as the parent container. Extra spacing will be added to the element's size without regards to the parent. This typically causes problems.

In my case I forgot to add providers: [INPUT_VALUE_ACCESSOR] to my custom component

I had INPUT_VALUE_ACCESSOR created as:

export const INPUT_VALUE_ACCESSOR = {
  provide: NG_VALUE_ACCESSOR,
  useExisting: forwardRef(() => TextEditorComponent),
  multi: true,
};

I have used JTextArea for multiline JLabels.

JTextArea textarea = new JTextArea ("1\n2\n3\n"+"4\n");

If using VueJS, import all the js dependencies for jQuery extensions first, then import $ second...

import "../assets/js/jquery-2.2.3.min.js"
import "../assets/js/jquery-ui-1.12.1.min.js"
import "../assets/js/jquery.validate.min.js"
import $ from "jquery";

You then need to use jquery from a javascript function called from a custom wrapper defined globally in the VueJS prototype method.

This safeguards use of jQuery and jQuery UI from fighting with VueJS.

Vue.prototype.$fValidateTag = function( sTag, rRules ) 
{
    return ValidateTag( sTag, rRules );
};

function ValidateTag( sTag, rRules )
{
    Var rTagT = $( sTag );
    return rParentTag.validate( sTag, rRules );
}

try this ,

$presentyear = '2013-08-16 12:00:00';

$nextyear  = date("M d,Y",mktime(0, 0, 0, date("m",strtotime($presentyear )),   date("d",strtotime($presentyear )),   date("Y",strtotime($presentyear ))+5));

echo $nextyear;

You can remove the time part of a date by using TRUNC.

select field,datetime_field 
  from database
 where datetime_field >= trunc(sysdate-1,'DD');

That query will give you all rows with dates starting from yesterday. Note the second argument to trunc(). You can use this to truncate any part of the date.

If your datetime_fied contains '2011-05-04 08:23:54', the following date will be returned

trunc(datetime_field, 'HH24') => 2011-05-04 08:00:00
trunc(datetime_field, 'DD')   => 2011-05-04 00:00:00
trunc(datetime_field, 'MM')   => 2011-05-01 00:00:00
trunc(datetime_field, 'YYYY') => 2011-00-01 00:00:00

First few lines: man head.

Append lines: use the >> operator (?) in Bash:

echo 'This goes at the end of the file' >> file

All the above method will work. but to use the var as env variable inside your code you need to export the var first.

script{
  sh " 'shell command here' > command"
  command_var = readFile('command').trim()
  sh "export command_var=$command_var"
}

replace the shell command with the command of your choice. Now if you are using python code you can just specify os.getenv("command_var") that will return the output of the shell command executed previously.

In order to use base_url(), you must first have the URL Helper loaded. This can be done either in application/config/autoload.php (on or around line 67):

$autoload['helper'] = array('url');

Or, manually:

$this->load->helper('url');

Once it's loaded, be sure to keep in mind that base_url() doesn't implicitly print or echo out anything, rather it returns the value to be printed:

echo base_url();

Remember also that the value returned is the site's base url as provided in the config file. CodeIgniter will accomodate an empty value in the config file as well:

If this (base_url) is not set then CodeIgniter will guess the protocol, domain and path to your installation.

application/config/config.php, line 13

There is a whole new approach that you may want to consider if what you're after is the power and performance of stored procedures, and the rapid development that tools like Entity Framework provide.

I've taken SQL+ for a test drive on a small project, and it is really something special. You basically add what amounts to comments to your SQL routines, and those comments provide instructions to a code generator, which then builds a really nice object oriented class library based on the actual SQL routine. Kind of like entity framework in reverse.

Input parameters become part of an input object, output parameters and result sets become part of an output object, and a service component provides the method calls.

If you want to use stored procedures, but still want rapid development, you might want to have a look at this stuff.

Another thing you could try is to upload the html to a webpage and then open the webpage in word to test Outlook.

Check Safari developer reference on Touch class.

According to this, pageX/Y should be available - maybe you should check spelling? make sure it's pageX and not PageX

you can use the pow method from the Math class. The following code will output 2 raised to 3 (8)

System.out.println(Math.pow(2, 3));

I have Windows 8 installed on my machine, and the aspnet_regiis.exe tool did not worked for me either.

The solution that worked for me is posted on this link, on the answer by Neha: System.ServiceModel.Activation.HttpModule error

Everywhere the problem to this solution was mentioned as re-registering aspNet by using aspnet_regiis.exe. But this did not work for me.

Though this is a valid solution (as explained beautifully here)

but it did not work with Windows 8.

For Windows 8 you need to Windows features and enable everything under ".Net Framework 3.5" and ".Net Framework 4.5 Advanced Services".

Thanks Neha

As mentioned in Vineet's answer, one possible reason you receive this error is due to incompatible cipher suites being used. By updating my local_policy and US_export_policy jars in my JDK's security folder with the ones provided in the Java Cryptography Extension (JCE), I was able to complete the handshake successfully.

You could call editText.invalidate() after you reset the hint color. That could resolve your issue. Actually the SDK update the color in the same way.

I would first concatenate the arrays, then I would return only the unique value.

You have to create your own function to return unique values. Since it is a useful function, you might as well add it in as a functionality of the Array.

In your case with arrays array1 and array2 it would look like this:

1. array1.concat(array2) - concatenate the two arrays
2. array1.concat(array2).unique() - return only the unique values. Here unique() is a method you added to the prototype for Array.

The whole thing would look like this:

Array.prototype.unique = function () {_x000D_
    var r = new Array();_x000D_
    o: for(var i = 0, n = this.length; i < n; i++)_x000D_
    {_x000D_
        for(var x = 0, y = r.length; x < y; x++)_x000D_
        {_x000D_
            if(r[x]==this[i])_x000D_
            {_x000D_
                continue o;_x000D_
            }_x000D_
        }_x000D_
        r[r.length] = this[i];_x000D_
    }_x000D_
    return r;_x000D_
}_x000D_
var array1 = [34,35,45,48,49];_x000D_
var array2 = [34,35,45,48,49,55];_x000D_
_x000D_
// concatenate the arrays then return only the unique values_x000D_
console.log(array1.concat(array2).unique());

Try using:

.button input, .button a {
    // css stuff
}

Also, read up on CSS.

Edit: If it were me, I'd add the button class to the element, not to the parent tag. Like so:

HTML:

<a href="#" class='button'>BUTTON TEXT</a>
<input type="submit" class='button' value='buttontext' />

CSS:

.button {
    // css stuff
}

For specific css stuff use:

input.button {
    // css stuff
}
a.button {
    // css stuff
}

If you want to browse code changes (see what actually has been changed with the given word in the whole history) go for patch mode - I found a very useful combination of doing:

git log -p
# Hit '/' for search mode.
# Type in the word you are searching.
# If the first search is not relevant, hit 'n' for next (like in Vim ;) )

node -v v9.10.1

If you try to console log query object directly you will get error TypeError: Cannot convert object to primitive value

So I would suggest use JSON.stringify

const http = require('http');
const url = require('url');

const server = http.createServer((req, res) => {
    const parsedUrl = url.parse(req.url, true);

    const path = parsedUrl.pathname, query = parsedUrl.query;
    const method = req.method;

    res.end("hello world\n");

    console.log(`Request received on: ${path} + method: ${method} + query: 
    ${JSON.stringify(query)}`);
    console.log('query: ', query);
  });


  server.listen(3000, () => console.log("Server running at port 3000"));

So doing curl http://localhost:3000/foo\?fizz\=buzz will return Request received on: /foo + method: GET + query: {"fizz":"buzz"}

Problem 1

You mentioned it was your private docker registry, so you probably need to check Registry API instead of Hub registry API doc, which is the link you provided.

Problem 2

docker registry API is a client/server protocol, it is up to the server's implementation on whether to remove the images in the back-end. (I guess)

DELETE /v1/repositories/(namespace)/(repository)/tags/(tag*)

Detailed explanation

Below I demo how it works now from your description as my understanding for your questions.

I run a private docker registry. I use the default one, and listen on port 5000.

docker run -d -p 5000:5000 registry

Then I tag the local image and push into it.

$ docker tag ubuntu localhost:5000/ubuntu
$ docker push localhost:5000/ubuntu
The push refers to a repository [localhost:5000/ubuntu] (len: 1)
Sending image list
Pushing repository localhost:5000/ubuntu (1 tags)
511136ea3c5a: Image successfully pushed
d7ac5e4f1812: Image successfully pushed
2f4b4d6a4a06: Image successfully pushed
83ff768040a0: Image successfully pushed
6c37f792ddac: Image successfully pushed
e54ca5efa2e9: Image successfully pushed
Pushing tag for rev [e54ca5efa2e9] on {http://localhost:5000/v1/repositories/ubuntu/tags/latest}

After that I can use Registry API to check it exists in your private docker registry

$ curl -X GET localhost:5000/v1/repositories/ubuntu/tags
{"latest": "e54ca5efa2e962582a223ca9810f7f1b62ea9b5c3975d14a5da79d3bf6020f37"}

Now I can delete the tag using that API !!

$ curl -X DELETE localhost:5000/v1/repositories/ubuntu/tags/latest
true

Check again, the tag doesn't exist in my private registry server

$ curl -X GET localhost:5000/v1/repositories/ubuntu/tags/latest
{"error": "Tag not found"}

You need to set option CURLOPT_PROXYTYPE to CURLPROXY_SOCKS5_HOSTNAME, which sadly wasn't defined in old PHP versions, circa pre-5.6; if you have earlier in but you can explicitly use its value, which is equal to 7:

curl_setopt($ch, CURLOPT_PROXYTYPE, 7);

scp -r C:/site user@server_ip:path

path is the place, where site will be copied into the remote server

EDIT: As I said in my comment, try pscp, as you want to use scp using PuTTY.

The other option is WinSCP

A simple view like this was giving me the ORA-01861 error when executed from Entity Framework:

create view myview as 
select * from x where x.initialDate >= '01FEB2021'

Just did something like this to fix it:

create view myview as 
select * from x where x.initialDate >= TO_DATE('2021-02-01', 'YYYY-MM-DD')

I think the problem is EF date configuration is not the same as Oracle's.

You could use xpath to accomplish this

var xpath = "//a[text()='SearchingText']";
var matchingElement = document.evaluate(xpath, document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue;

You can also search of an element containing some text using this xpath:

var xpath = "//a[contains(text(),'Searching')]";
