Programs & Examples On #Nszombieenabled

I find this alternative more convenient:

1. Click the "Run Button Dropdown"
2. From the list choose Profile
3. The program "Instruments" should open where you can also choose Zombies
4. Now you can interact with your app and try to cause the error
5. As soon as the error happens you should get a hint on when your object was released and therefore deallocated.

As soon as a zombie is detected you then get a neat "Zombie Stack" that shows you when the object in question was allocated and where it was retained or released:

Event Type    RefCt     Responsible Caller
Malloc            1     -[MyViewController loadData:]
Retain            2     -[MyDataManager initWithBaseURL:]
Release           1     -[MyDataManager initWithBaseURL:]
Release           0     -[MyViewController loadData:]
Zombie           -1     -[MyService prepareURLReuqest]

Advantages compared to using the diagnostic tab of the Xcode Schemes:

1. If you forget to uncheck the option in the diagnostic tab there no objects will be released from memory.

2. You get a more detailed stack that shows you in what methods your corrupt object was allocated / released or retained.

Here's your one-liner, without using any regular expressions, which can get expensive at times:

>>> ''.join(filter(str.isdigit, "1234GAgade5312djdl0"))

returns:

'123453120'

Right Click on the server tab, go for NEW-> Server. then choose recent version of tomcat server. Click on next, and then give path for your tomcat server.(You can download tomcat server from this link https://tomcat.apache.org/download-80.cgi#8.5.32). Click on finish.

You can start your server now..!!

MVC 4:

    function Cargar_BS(bs) {
        $.getJSON('@Url.Action("GetBienServicio", "MonitoreoAdministracion")',
                        {
                            id: bs
                        },
                        function (d) {
                            $("#txtIdItem").empty().append('<option value="">-Seleccione-</option>');
                            $.each(d, function (idx, item) {
                                jQuery("<option/>").text(item.C_DescBs).attr("value", item.C_CodBs).appendTo("#txtIdItem");
                            })
                            $('#txtIdItem').trigger("chosen:updated");
                        });
    }

If it says the API key is listed as a header, more than likely you need to set it in the headers option of your http request. Normally something like this :

headers: {'Authorization': '[your API key]'}

Here is an example from another Question

$http({method: 'GET', url: '[the-target-url]', headers: {
  'Authorization': '[your-api-key]'}
});

Edit : Just saw you wanted to store the response in a variable. In this case I would probably just use AJAX. Something like this :

$.ajax({ 
   type : "GET", 
   url : "[the-target-url]", 
   beforeSend: function(xhr){xhr.setRequestHeader('Authorization', '[your-api-key]');},
   success : function(result) { 
       //set your variable to the result 
   }, 
   error : function(result) { 
     //handle the error 
   } 
 }); 

I got this from this question and I'm at work so I can't test it at the moment but looks solid

Edit 2: Pretty sure you should be able to use this line :

headers: {'Authorization': '[your API key]'},

instead of the beforeSend line in the first edit. This may be simpler for you

Numpy has a convenience function, np.fft.fftfreq to compute the frequencies associated with FFT components:

from __future__ import division
import numpy as np
import matplotlib.pyplot as plt

data = np.random.rand(301) - 0.5
ps = np.abs(np.fft.fft(data))**2

time_step = 1 / 30
freqs = np.fft.fftfreq(data.size, time_step)
idx = np.argsort(freqs)

plt.plot(freqs[idx], ps[idx])

Note that the largest frequency you see in your case is not 30 Hz, but

In [7]: max(freqs)
Out[7]: 14.950166112956811

You never see the sampling frequency in a power spectrum. If you had had an even number of samples, then you would have reached the Nyquist frequency, 15 Hz in your case (although numpy would have calculated it as -15).

The top answers are great, but as mentioned by @paul-van-leeuwen and @quasimodos-clone, PHP 7.3 will introduce two new functions to solve this problem directly - array_key_first() and array_key_last().

You can start using this syntax today with the following polyfill (or shim) functions.

// Polyfill for array_key_last() available from PHP 7.3
if (!function_exists('array_key_last')) {
  function array_key_last($array) {
    return array_slice(array_keys($array),-1)[0];
  }
}

// Polyfill for array_key_first() available from PHP 7.3
if (!function_exists('array_key_first')) {
  function array_key_first($array) {
    return array_slice(array_keys($array),0)[0];
  }
}

// Usage examples:
$first_element_key   = array_key_first($array);
$first_element_value = $array[array_key_first($array)];

$last_element_key    = array_key_last($array);
$last_element_value  = $array[array_key_last($array)];

Caveat: This requires PHP 5.4 or greater.

As one of the answers above says: " then drag the formula fill handle." This KEY feature is not mentioned in MS's explanation, nor in others here. I spent over an hour trying to follow the various instructions, to no avail. This is because you have to click and hold near the bottom of the cell just right (and at least on my computer that is not at all easy) so that a sort of "handle" appears. Once you're luck enough to get that, then carefully slide ["drag"] your cursor down to the lowermost of the cells you want to be multiplied by the constant. The products should show up in each cell as you move down. Just dragging down will give you only the answer in the first cell and a lot of white space.

You can use

document.querySelector('your-element').scrollIntoView({behavior: 'smooth'});

If you want to scroll top the top of the page, you can just place an empty element in the top, and smooth scroll to that one.

First you store your text file in to raw folder.

private void loadWords() throws IOException {
    Log.d(TAG, "Loading words...");
    final Resources resources = mHelperContext.getResources();
    InputStream inputStream = resources.openRawResource(R.raw.definitions);
    BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));

    try {
        String line;
        while ((line = reader.readLine()) != null) {
            String[] strings = TextUtils.split(line, "-");
            if (strings.length < 2)
                continue;
            long id = addWord(strings[0].trim(), strings[1].trim());
            if (id < 0) {
                Log.e(TAG, "unable to add word: " + strings[0].trim());
            }
        }
    } finally {
        reader.close();
    }
    Log.d(TAG, "DONE loading words.");
}

If the decimal separator is comma (eg : LC_NUMERIC=fr_FR.UTF-8, see here):

$ printf "%.0f" $(echo "scale=2;3/2" | bc) 
bash: printf: 1.50: nombre non valable
0

Substitution is needed for ghostdog74 solution :

$ printf "%.0f" $(echo "scale=2;3/2" | bc | sed 's/[.]/,/')
2

or

$ printf "%.0f" $(echo "scale=2;3/2" | bc | tr '.' ',')
2

You can do that in this way:

export enum GoalProgressMeasurements {
    Percentage = 1,
    Numeric_Target = 2,
    Completed_Tasks = 3,
    Average_Milestone_Progress = 4,
    Not_Measured = 5
}

export class GoalProgressMeasurement {
    constructor(public goalProgressMeasurement: GoalProgressMeasurements, public name: string) {
    }
}

export var goalProgressMeasurements: { [key: number]: GoalProgressMeasurement } = {
    1: new GoalProgressMeasurement(GoalProgressMeasurements.Percentage, "Percentage"),
    2: new GoalProgressMeasurement(GoalProgressMeasurements.Numeric_Target, "Numeric Target"),
    3: new GoalProgressMeasurement(GoalProgressMeasurements.Completed_Tasks, "Completed Tasks"),
    4: new GoalProgressMeasurement(GoalProgressMeasurements.Average_Milestone_Progress, "Average Milestone Progress"),
    5: new GoalProgressMeasurement(GoalProgressMeasurements.Not_Measured, "Not Measured"),
}

And you can use it like this:

var gpm: GoalProgressMeasurement = goalProgressMeasurements[GoalProgressMeasurements.Percentage];
var gpmName: string = gpm.name;

var myProgressId: number = 1; // the value can come out of drop down selected value or from back-end , so you can imagine the way of using
var gpm2: GoalProgressMeasurement = goalProgressMeasurements[myProgressId];
var gpmName: string = gpm.name;

You can extend the GoalProgressMeasurement with additional properties of the object as you need. I'm using this approach for every enumeration that should be an object containing more then a value.

All of the answers to this question are wrong in one way or another.

Wrong answer #1

IFS=', ' read -r -a array <<< "$string"

1: This is a misuse of $IFS. The value of the $IFS variable is not taken as a single variable-length string separator, rather it is taken as a set of single-character string separators, where each field that read splits off from the input line can be terminated by any character in the set (comma or space, in this example).

Actually, for the real sticklers out there, the full meaning of $IFS is slightly more involved. From the bash manual:

The shell treats each character of IFS as a delimiter, and splits the results of the other expansions into words using these characters as field terminators. If IFS is unset, or its value is exactly <space><tab><newline>, the default, then sequences of <space>, <tab>, and <newline> at the beginning and end of the results of the previous expansions are ignored, and any sequence of IFS characters not at the beginning or end serves to delimit words. If IFS has a value other than the default, then sequences of the whitespace characters <space>, <tab>, and <newline> are ignored at the beginning and end of the word, as long as the whitespace character is in the value of IFS (an IFS whitespace character). Any character in IFS that is not IFS whitespace, along with any adjacent IFS whitespace characters, delimits a field. A sequence of IFS whitespace characters is also treated as a delimiter. If the value of IFS is null, no word splitting occurs.

Basically, for non-default non-null values of $IFS, fields can be separated with either (1) a sequence of one or more characters that are all from the set of "IFS whitespace characters" (that is, whichever of <space>, <tab>, and <newline> ("newline" meaning line feed (LF)) are present anywhere in $IFS), or (2) any non-"IFS whitespace character" that's present in $IFS along with whatever "IFS whitespace characters" surround it in the input line.

For the OP, it's possible that the second separation mode I described in the previous paragraph is exactly what he wants for his input string, but we can be pretty confident that the first separation mode I described is not correct at all. For example, what if his input string was 'Los Angeles, United States, North America'?

IFS=', ' read -ra a <<<'Los Angeles, United States, North America'; declare -p a;
## declare -a a=([0]="Los" [1]="Angeles" [2]="United" [3]="States" [4]="North" [5]="America")

2: Even if you were to use this solution with a single-character separator (such as a comma by itself, that is, with no following space or other baggage), if the value of the $string variable happens to contain any LFs, then read will stop processing once it encounters the first LF. The read builtin only processes one line per invocation. This is true even if you are piping or redirecting input only to the read statement, as we are doing in this example with the here-string mechanism, and thus unprocessed input is guaranteed to be lost. The code that powers the read builtin has no knowledge of the data flow within its containing command structure.

You could argue that this is unlikely to cause a problem, but still, it's a subtle hazard that should be avoided if possible. It is caused by the fact that the read builtin actually does two levels of input splitting: first into lines, then into fields. Since the OP only wants one level of splitting, this usage of the read builtin is not appropriate, and we should avoid it.

3: A non-obvious potential issue with this solution is that read always drops the trailing field if it is empty, although it preserves empty fields otherwise. Here's a demo:

string=', , a, , b, c, , , '; IFS=', ' read -ra a <<<"$string"; declare -p a;
## declare -a a=([0]="" [1]="" [2]="a" [3]="" [4]="b" [5]="c" [6]="" [7]="")

Maybe the OP wouldn't care about this, but it's still a limitation worth knowing about. It reduces the robustness and generality of the solution.

This problem can be solved by appending a dummy trailing delimiter to the input string just prior to feeding it to read, as I will demonstrate later.

Wrong answer #2

string="1:2:3:4:5"
set -f                     # avoid globbing (expansion of *).
array=(${string//:/ })

Similar idea:

t="one,two,three"
a=($(echo $t | tr ',' "\n"))

(Note: I added the missing parentheses around the command substitution which the answerer seems to have omitted.)

Similar idea:

string="1,2,3,4"
array=(`echo $string | sed 's/,/\n/g'`)

These solutions leverage word splitting in an array assignment to split the string into fields. Funnily enough, just like read, general word splitting also uses the $IFS special variable, although in this case it is implied that it is set to its default value of <space><tab><newline>, and therefore any sequence of one or more IFS characters (which are all whitespace characters now) is considered to be a field delimiter.

This solves the problem of two levels of splitting committed by read, since word splitting by itself constitutes only one level of splitting. But just as before, the problem here is that the individual fields in the input string can already contain $IFS characters, and thus they would be improperly split during the word splitting operation. This happens to not be the case for any of the sample input strings provided by these answerers (how convenient...), but of course that doesn't change the fact that any code base that used this idiom would then run the risk of blowing up if this assumption were ever violated at some point down the line. Once again, consider my counterexample of 'Los Angeles, United States, North America' (or 'Los Angeles:United States:North America').

Also, word splitting is normally followed by filename expansion (aka pathname expansion aka globbing), which, if done, would potentially corrupt words containing the characters *, ?, or [ followed by ] (and, if extglob is set, parenthesized fragments preceded by ?, *, +, @, or !) by matching them against file system objects and expanding the words ("globs") accordingly. The first of these three answerers has cleverly undercut this problem by running set -f beforehand to disable globbing. Technically this works (although you should probably add set +f afterward to reenable globbing for subsequent code which may depend on it), but it's undesirable to have to mess with global shell settings in order to hack a basic string-to-array parsing operation in local code.

Another issue with this answer is that all empty fields will be lost. This may or may not be a problem, depending on the application.

Note: If you're going to use this solution, it's better to use the ${string//:/ } "pattern substitution" form of parameter expansion, rather than going to the trouble of invoking a command substitution (which forks the shell), starting up a pipeline, and running an external executable (tr or sed), since parameter expansion is purely a shell-internal operation. (Also, for the tr and sed solutions, the input variable should be double-quoted inside the command substitution; otherwise word splitting would take effect in the echo command and potentially mess with the field values. Also, the $(...) form of command substitution is preferable to the old `...` form since it simplifies nesting of command substitutions and allows for better syntax highlighting by text editors.)

Wrong answer #3

str="a, b, c, d"  # assuming there is a space after ',' as in Q
arr=(${str//,/})  # delete all occurrences of ','

This answer is almost the same as #2. The difference is that the answerer has made the assumption that the fields are delimited by two characters, one of which being represented in the default $IFS, and the other not. He has solved this rather specific case by removing the non-IFS-represented character using a pattern substitution expansion and then using word splitting to split the fields on the surviving IFS-represented delimiter character.

This is not a very generic solution. Furthermore, it can be argued that the comma is really the "primary" delimiter character here, and that stripping it and then depending on the space character for field splitting is simply wrong. Once again, consider my counterexample: 'Los Angeles, United States, North America'.

Also, again, filename expansion could corrupt the expanded words, but this can be prevented by temporarily disabling globbing for the assignment with set -f and then set +f.

Also, again, all empty fields will be lost, which may or may not be a problem depending on the application.

Wrong answer #4

string='first line
second line
third line'

oldIFS="$IFS"
IFS='
'
IFS=${IFS:0:1} # this is useful to format your code with tabs
lines=( $string )
IFS="$oldIFS"

This is similar to #2 and #3 in that it uses word splitting to get the job done, only now the code explicitly sets $IFS to contain only the single-character field delimiter present in the input string. It should be repeated that this cannot work for multicharacter field delimiters such as the OP's comma-space delimiter. But for a single-character delimiter like the LF used in this example, it actually comes close to being perfect. The fields cannot be unintentionally split in the middle as we saw with previous wrong answers, and there is only one level of splitting, as required.

One problem is that filename expansion will corrupt affected words as described earlier, although once again this can be solved by wrapping the critical statement in set -f and set +f.

Another potential problem is that, since LF qualifies as an "IFS whitespace character" as defined earlier, all empty fields will be lost, just as in #2 and #3. This would of course not be a problem if the delimiter happens to be a non-"IFS whitespace character", and depending on the application it may not matter anyway, but it does vitiate the generality of the solution.

So, to sum up, assuming you have a one-character delimiter, and it is either a non-"IFS whitespace character" or you don't care about empty fields, and you wrap the critical statement in set -f and set +f, then this solution works, but otherwise not.

(Also, for information's sake, assigning a LF to a variable in bash can be done more easily with the $'...' syntax, e.g. IFS=$'\n';.)

Wrong answer #5

countries='Paris, France, Europe'
OIFS="$IFS"
IFS=', ' array=($countries)
IFS="$OIFS"

Similar idea:

IFS=', ' eval 'array=($string)'

This solution is effectively a cross between #1 (in that it sets $IFS to comma-space) and #2-4 (in that it uses word splitting to split the string into fields). Because of this, it suffers from most of the problems that afflict all of the above wrong answers, sort of like the worst of all worlds.

Also, regarding the second variant, it may seem like the eval call is completely unnecessary, since its argument is a single-quoted string literal, and therefore is statically known. But there's actually a very non-obvious benefit to using eval in this way. Normally, when you run a simple command which consists of a variable assignment only, meaning without an actual command word following it, the assignment takes effect in the shell environment:

IFS=', '; ## changes $IFS in the shell environment

This is true even if the simple command involves multiple variable assignments; again, as long as there's no command word, all variable assignments affect the shell environment:

IFS=', ' array=($countries); ## changes both $IFS and $array in the shell environment

But, if the variable assignment is attached to a command name (I like to call this a "prefix assignment") then it does not affect the shell environment, and instead only affects the environment of the executed command, regardless whether it is a builtin or external:

IFS=', ' :; ## : is a builtin command, the $IFS assignment does not outlive it
IFS=', ' env; ## env is an external command, the $IFS assignment does not outlive it

Relevant quote from the bash manual:

If no command name results, the variable assignments affect the current shell environment. Otherwise, the variables are added to the environment of the executed command and do not affect the current shell environment.

It is possible to exploit this feature of variable assignment to change $IFS only temporarily, which allows us to avoid the whole save-and-restore gambit like that which is being done with the $OIFS variable in the first variant. But the challenge we face here is that the command we need to run is itself a mere variable assignment, and hence it would not involve a command word to make the $IFS assignment temporary. You might think to yourself, well why not just add a no-op command word to the statement like the : builtin to make the $IFS assignment temporary? This does not work because it would then make the $array assignment temporary as well:

IFS=', ' array=($countries) :; ## fails; new $array value never escapes the : command

So, we're effectively at an impasse, a bit of a catch-22. But, when eval runs its code, it runs it in the shell environment, as if it was normal, static source code, and therefore we can run the $array assignment inside the eval argument to have it take effect in the shell environment, while the $IFS prefix assignment that is prefixed to the eval command will not outlive the eval command. This is exactly the trick that is being used in the second variant of this solution:

IFS=', ' eval 'array=($string)'; ## $IFS does not outlive the eval command, but $array does

So, as you can see, it's actually quite a clever trick, and accomplishes exactly what is required (at least with respect to assignment effectation) in a rather non-obvious way. I'm actually not against this trick in general, despite the involvement of eval; just be careful to single-quote the argument string to guard against security threats.

But again, because of the "worst of all worlds" agglomeration of problems, this is still a wrong answer to the OP's requirement.

Wrong answer #6

IFS=', '; array=(Paris, France, Europe)

IFS=' ';declare -a array=(Paris France Europe)

Um... what? The OP has a string variable that needs to be parsed into an array. This "answer" starts with the verbatim contents of the input string pasted into an array literal. I guess that's one way to do it.

It looks like the answerer may have assumed that the $IFS variable affects all bash parsing in all contexts, which is not true. From the bash manual:

IFS    The Internal Field Separator that is used for word splitting after expansion and to split lines into words with the read builtin command. The default value is <space><tab><newline>.

So the $IFS special variable is actually only used in two contexts: (1) word splitting that is performed after expansion (meaning not when parsing bash source code) and (2) for splitting input lines into words by the read builtin.

Let me try to make this clearer. I think it might be good to draw a distinction between parsing and execution. Bash must first parse the source code, which obviously is a parsing event, and then later it executes the code, which is when expansion comes into the picture. Expansion is really an execution event. Furthermore, I take issue with the description of the $IFS variable that I just quoted above; rather than saying that word splitting is performed after expansion, I would say that word splitting is performed during expansion, or, perhaps even more precisely, word splitting is part of the expansion process. The phrase "word splitting" refers only to this step of expansion; it should never be used to refer to the parsing of bash source code, although unfortunately the docs do seem to throw around the words "split" and "words" a lot. Here's a relevant excerpt from the linux.die.net version of the bash manual:

Expansion is performed on the command line after it has been split into words. There are seven kinds of expansion performed: brace expansion, tilde expansion, parameter and variable expansion, command substitution, arithmetic expansion, word splitting, and pathname expansion.

The order of expansions is: brace expansion; tilde expansion, parameter and variable expansion, arithmetic expansion, and command substitution (done in a left-to-right fashion); word splitting; and pathname expansion.

You could argue the GNU version of the manual does slightly better, since it opts for the word "tokens" instead of "words" in the first sentence of the Expansion section:

Expansion is performed on the command line after it has been split into tokens.

The important point is, $IFS does not change the way bash parses source code. Parsing of bash source code is actually a very complex process that involves recognition of the various elements of shell grammar, such as command sequences, command lists, pipelines, parameter expansions, arithmetic substitutions, and command substitutions. For the most part, the bash parsing process cannot be altered by user-level actions like variable assignments (actually, there are some minor exceptions to this rule; for example, see the various compatxx shell settings, which can change certain aspects of parsing behavior on-the-fly). The upstream "words"/"tokens" that result from this complex parsing process are then expanded according to the general process of "expansion" as broken down in the above documentation excerpts, where word splitting of the expanded (expanding?) text into downstream words is simply one step of that process. Word splitting only touches text that has been spit out of a preceding expansion step; it does not affect literal text that was parsed right off the source bytestream.

Wrong answer #7

string='first line
        second line
        third line'

while read -r line; do lines+=("$line"); done <<<"$string"

This is one of the best solutions. Notice that we're back to using read. Didn't I say earlier that read is inappropriate because it performs two levels of splitting, when we only need one? The trick here is that you can call read in such a way that it effectively only does one level of splitting, specifically by splitting off only one field per invocation, which necessitates the cost of having to call it repeatedly in a loop. It's a bit of a sleight of hand, but it works.

But there are problems. First: When you provide at least one NAME argument to read, it automatically ignores leading and trailing whitespace in each field that is split off from the input string. This occurs whether $IFS is set to its default value or not, as described earlier in this post. Now, the OP may not care about this for his specific use-case, and in fact, it may be a desirable feature of the parsing behavior. But not everyone who wants to parse a string into fields will want this. There is a solution, however: A somewhat non-obvious usage of read is to pass zero NAME arguments. In this case, read will store the entire input line that it gets from the input stream in a variable named $REPLY, and, as a bonus, it does not strip leading and trailing whitespace from the value. This is a very robust usage of read which I've exploited frequently in my shell programming career. Here's a demonstration of the difference in behavior:

string=$'  a  b  \n  c  d  \n  e  f  '; ## input string

a=(); while read -r line; do a+=("$line"); done <<<"$string"; declare -p a;
## declare -a a=([0]="a  b" [1]="c  d" [2]="e  f") ## read trimmed surrounding whitespace

a=(); while read -r; do a+=("$REPLY"); done <<<"$string"; declare -p a;
## declare -a a=([0]="  a  b  " [1]="  c  d  " [2]="  e  f  ") ## no trimming

The second issue with this solution is that it does not actually address the case of a custom field separator, such as the OP's comma-space. As before, multicharacter separators are not supported, which is an unfortunate limitation of this solution. We could try to at least split on comma by specifying the separator to the -d option, but look what happens:

string='Paris, France, Europe';
a=(); while read -rd,; do a+=("$REPLY"); done <<<"$string"; declare -p a;
## declare -a a=([0]="Paris" [1]=" France")

Predictably, the unaccounted surrounding whitespace got pulled into the field values, and hence this would have to be corrected subsequently through trimming operations (this could also be done directly in the while-loop). But there's another obvious error: Europe is missing! What happened to it? The answer is that read returns a failing return code if it hits end-of-file (in this case we can call it end-of-string) without encountering a final field terminator on the final field. This causes the while-loop to break prematurely and we lose the final field.

Technically this same error afflicted the previous examples as well; the difference there is that the field separator was taken to be LF, which is the default when you don't specify the -d option, and the <<< ("here-string") mechanism automatically appends a LF to the string just before it feeds it as input to the command. Hence, in those cases, we sort of accidentally solved the problem of a dropped final field by unwittingly appending an additional dummy terminator to the input. Let's call this solution the "dummy-terminator" solution. We can apply the dummy-terminator solution manually for any custom delimiter by concatenating it against the input string ourselves when instantiating it in the here-string:

a=(); while read -rd,; do a+=("$REPLY"); done <<<"$string,"; declare -p a;
declare -a a=([0]="Paris" [1]=" France" [2]=" Europe")

There, problem solved. Another solution is to only break the while-loop if both (1) read returned failure and (2) $REPLY is empty, meaning read was not able to read any characters prior to hitting end-of-file. Demo:

a=(); while read -rd,|| [[ -n "$REPLY" ]]; do a+=("$REPLY"); done <<<"$string"; declare -p a;
## declare -a a=([0]="Paris" [1]=" France" [2]=$' Europe\n')

This approach also reveals the secretive LF that automatically gets appended to the here-string by the <<< redirection operator. It could of course be stripped off separately through an explicit trimming operation as described a moment ago, but obviously the manual dummy-terminator approach solves it directly, so we could just go with that. The manual dummy-terminator solution is actually quite convenient in that it solves both of these two problems (the dropped-final-field problem and the appended-LF problem) in one go.

So, overall, this is quite a powerful solution. It's only remaining weakness is a lack of support for multicharacter delimiters, which I will address later.

Wrong answer #8

string='first line
        second line
        third line'

readarray -t lines <<<"$string"

(This is actually from the same post as #7; the answerer provided two solutions in the same post.)

The readarray builtin, which is a synonym for mapfile, is ideal. It's a builtin command which parses a bytestream into an array variable in one shot; no messing with loops, conditionals, substitutions, or anything else. And it doesn't surreptitiously strip any whitespace from the input string. And (if -O is not given) it conveniently clears the target array before assigning to it. But it's still not perfect, hence my criticism of it as a "wrong answer".

First, just to get this out of the way, note that, just like the behavior of read when doing field-parsing, readarray drops the trailing field if it is empty. Again, this is probably not a concern for the OP, but it could be for some use-cases. I'll come back to this in a moment.

Second, as before, it does not support multicharacter delimiters. I'll give a fix for this in a moment as well.

Third, the solution as written does not parse the OP's input string, and in fact, it cannot be used as-is to parse it. I'll expand on this momentarily as well.

For the above reasons, I still consider this to be a "wrong answer" to the OP's question. Below I'll give what I consider to be the right answer.

Right answer

Here's a naïve attempt to make #8 work by just specifying the -d option:

string='Paris, France, Europe';
readarray -td, a <<<"$string"; declare -p a;
## declare -a a=([0]="Paris" [1]=" France" [2]=$' Europe\n')

We see the result is identical to the result we got from the double-conditional approach of the looping read solution discussed in #7. We can almost solve this with the manual dummy-terminator trick:

readarray -td, a <<<"$string,"; declare -p a;
## declare -a a=([0]="Paris" [1]=" France" [2]=" Europe" [3]=$'\n')

The problem here is that readarray preserved the trailing field, since the <<< redirection operator appended the LF to the input string, and therefore the trailing field was not empty (otherwise it would've been dropped). We can take care of this by explicitly unsetting the final array element after-the-fact:

readarray -td, a <<<"$string,"; unset 'a[-1]'; declare -p a;
## declare -a a=([0]="Paris" [1]=" France" [2]=" Europe")

The only two problems that remain, which are actually related, are (1) the extraneous whitespace that needs to be trimmed, and (2) the lack of support for multicharacter delimiters.

The whitespace could of course be trimmed afterward (for example, see How to trim whitespace from a Bash variable?). But if we can hack a multicharacter delimiter, then that would solve both problems in one shot.

Unfortunately, there's no direct way to get a multicharacter delimiter to work. The best solution I've thought of is to preprocess the input string to replace the multicharacter delimiter with a single-character delimiter that will be guaranteed not to collide with the contents of the input string. The only character that has this guarantee is the NUL byte. This is because, in bash (though not in zsh, incidentally), variables cannot contain the NUL byte. This preprocessing step can be done inline in a process substitution. Here's how to do it using awk:

readarray -td '' a < <(awk '{ gsub(/, /,"\0"); print; }' <<<"$string, "); unset 'a[-1]';
declare -p a;
## declare -a a=([0]="Paris" [1]="France" [2]="Europe")

There, finally! This solution will not erroneously split fields in the middle, will not cut out prematurely, will not drop empty fields, will not corrupt itself on filename expansions, will not automatically strip leading and trailing whitespace, will not leave a stowaway LF on the end, does not require loops, and does not settle for a single-character delimiter.

Trimming solution

Lastly,

$.ajax({
  url: '//.xml',
  dataType: 'xml',
  success: onTrue,
  error: function (err) {
      console.error('Error: ', err);
  }
});

$('a').each(function () {
  $(this).click(function (e) {
      var l = e.target.text;
      //array.sort(sorteerOp(l));
      //functionToAdaptHtml();
  });
});

1. go to your image in windows and copy it
2. go to the res folder and select one of the drawable folders and paste the image in there
3. click on imageview then go to properties and scroll down until you see src
4. insert this into src @drawable/imagename

I am sure this can help. Create fileA anywhere in the directory and export all the functions.

export const func1=()=>{
    // do stuff
}
export const func2=()=>{
    // do stuff 
}
export const func3=()=>{
    // do stuff 
}
export const func4=()=>{
    // do stuff 
}
export const func5=()=>{
    // do stuff 
}

Here, in your React component class, you can simply write one import statement.

import React from 'react';
import {func1,func2,func3} from 'path_to_fileA';

class HtmlComponents extends React.Component {
    constructor(props){
        super(props);
        this.rippleClickFunction=this.rippleClickFunction.bind(this);
    }
    rippleClickFunction(){
        //do stuff. 
        // foo==bar
        func1(data);
        func2(data)
    }
   render() {
      return (
         <article>
             <h1>React Components</h1>
             <RippleButton onClick={this.rippleClickFunction}/>
         </article>
      );
   }
}

export default HtmlComponents;

This is not perfect, but it works.

<asp:LinkButton id="lbnkVidTtile1" runat="Server" 
    CssClass="bodytext" Text='<%# Eval("newvideotitle") %>'
    OnClientClick="return PostToNewWindow();"  />

    originalTarget = document.forms[0].target;
    document.forms[0].target='_blank';
    window.setTimeout("document.forms[0].target=originalTarget;",300);
    return true;

Read the manual, it covers it very well: http://php.net/manual/en/function.mysql-query.php

Usually you do something like this:

while ($row = mysql_fetch_assoc($result)) {
  echo $row['firstname'];
  echo $row['lastname'];
  echo $row['address'];
  echo $row['age'];
}

Try javax.net.ssl.keyStorePassword instead of javax.net.ssl.keyPassword: the latter isn't mentioned in the JSSE ref guide.

The algorithms you mention should be there by default using the default security providers. NoSuchAlgorithmExceptions are often cause by other underlying exceptions (file not found, wrong password, wrong keystore type, ...). It's useful to look at the full stack trace.

You could also use -Djavax.net.debug=ssl, or at least -Djavax.net.debug=ssl,keymanager, to get more debugging information, if the information in the stack trace isn't sufficient.

I think you should call the super.draw() method first before you do anything in surfaceView's draw method.

If you have used Powershell commands to set the Proxy on windows machine doing the below helped me.

To unset the proxy use: 1. Open powershell 2. Enter the following:

[Environment]::SetEnvironmentVariable(“HTTP_PROXY”, $null, [EnvironmentVariableTarget]::Machine)
[Environment]::SetEnvironmentVariable(“HTTPS_PROXY”, $null, [EnvironmentVariableTarget]::Machine)

To set the proxy again use: 1. Open powershell 2. Enter the following:

[Environment]::SetEnvironmentVariable(“HTTP_PROXY”, “http://yourproxy.com:yourportnumber”, [EnvironmentVariableTarget]::Machine)
[Environment]::SetEnvironmentVariable(“HTTPS_PROXY”, “http://yourproxy.com:yourportnumber”, [EnvironmentVariableTarget]::Machine)

val intentAct: Intent = Intent(this@YourCurrentActivity, TagentActivity::class.java)

There are many ways to filter for element ancestors.

if ($elem.closest('.parentClass').length /* > 0*/) {/*...*/}
if ($elem.parents('.parentClass').length /* > 0*/) {/*...*/}
if ($elem.parents().hasClass('parentClass')) {/*...*/}
if ($('.parentClass').has($elem).length /* > 0*/) {/*...*/}
if ($elem.is('.parentClass *')) {/*...*/} 

Beware, closest() method includes element itself while checking for selector.

Alternatively, if you have a unique selector matching the $elem, e.g #myElem, you can use:

if ($('.parentClass:has(#myElem)').length /* > 0*/) {/*...*/}
if(document.querySelector('.parentClass #myElem')) {/*...*/}

If you want to match an element depending any of its ancestor class for styling purpose only, just use a CSS rule:

.parentClass #myElem { /* CSS property set */ }

The below css code always keep the button at the bottom of the page

position:absolute;
bottom:0;

Since you want to do it in relative positioning, you should go for margin-top:100%

position:relative;
margin-top:100%;

EDIT1: JSFiddle1

EDIT2: To place button at center of the screen,

position:relative;
left: 50%;
margin-top:50%;

$value = ( array_key_exists($key, $array) && !empty($array[$key]) ) 
         ? $array[$key] 
         : 'non-existant or empty value key';

use

window.location.replace("login.php");

or simply window.location("login.php");

It is better than using window.location.href =, because replace() does not put the originating page in the session history, meaning the user won't get stuck in a never-ending back-button fiasco. If you want to simulate someone clicking on a link, use location.href. If you want to simulate an HTTP redirect, use location.replace.

The easier way is through the web management console:

1. go to the instance
2. select the instance and click on instance action
3. create image

Once you have an image you can launch another cloned instance, data and all. :)

Maybe it´s too late but I solved this issue in a very simple way, I am using the Multicell option and the text come from a form, if I use an input field to get the text I can´t insert line breaks in any way, but if use a textarea field, the line breaks in the text area are line breaks in the multicell ... and that´s it, it works even if I use utf8_encode($text) option to preserve accents

It doesn't exist at first. You have to create it in your home folder, /Users/usename/.m2/ (or ~/.m2)

For example :

Because this is a frequent viewed question, I want to mention that a PowerShell function should use approved verbs (Verb-Noun as the function name). The verb part of the name identifies the action that the cmdlet performs. The noun part of the name identifies the entity on which the action is performed. This rule simplifies the usage of your cmdlets for advanced PowerShell users.

Also, you can specify things like whether the parameter is mandatory and the position of the parameter:

function Test-Script
{
    [CmdletBinding()]
    Param
    (
        [Parameter(Mandatory=$true, Position=0)]
        [string]$arg1,

        [Parameter(Mandatory=$true, Position=1)]
        [string]$arg2
    )

    Write-Host "`$arg1 value: $arg1"
    Write-Host "`$arg2 value: $arg2"
}

To pass the parameter to the function you can either use the position:

Test-Script "Hello" "World"

Or you specify the parameter name:

Test-Script -arg1 "Hello" -arg2 "World"

You don't use parentheses like you do when you call a function within C#.

I would recommend to always pass the parameter names when using more than one parameter, since this is more readable.

Your problem is not actually specific to ejs.

2 things to note here

1. style.css is an external css file. So you dont need style tags inside that file. It should only contain the css.

2. In your express app, you have to mention the public directory from which you are serving the static files. Like css/js/image

it can be done by

app.use(express.static(__dirname + '/public'));

assuming you put the css files in public folder from in your app root. now you have to refer to the css files in your tamplate files, like

<link href="/css/style.css" rel="stylesheet" type="text/css">

Here i assume you have put the css file in css folder inside your public folder.

So folder structure would be

.
./app.js
./public
    /css
        /style.css

instanceof works for instences of the same class or its subclasses

You can use it to test if an object is an instance of a class, an instance of a subclass, or an instance of a class that implements a particular interface.

ArryaList and RoleList are both instanceof List

While

getClass() == o.getClass() will be true only if both objects ( this and o ) belongs to exactly the same class.

So depending on what you need to compare you could use one or the other.

If your logic is: "One objects is equals to other only if they are both the same class" you should go for the "equals", which I think is most of the cases.

It allows the differentiation of bitwise const and logical const. Logical const is when an object doesn't change in a way that is visible through the public interface, like your locking example. Another example would be a class that computes a value the first time it is requested, and caches the result.

Since c++11 mutable can be used on a lambda to denote that things captured by value are modifiable (they aren't by default):

int x = 0;
auto f1 = [=]() mutable {x = 42;};  // OK
auto f2 = [=]()         {x = 42;};  // Error: a by-value capture cannot be modified in a non-mutable lambda

Type in:

man lsof

Then look for -w, -n, and -i

-i: internet stuff -n: makes it faster -w: toggles warnings

There are WAY more details on the man pages

It's possible in ggplot and you can use scale_date for this task

 library(ggplot2)

    dm <- read.table(textConnection(Lines), header = TRUE)
    dm <- mutate(dm, Date = as.Date(dm$Date, "%m/%d/%Y"))
    ggplot(data = dm, aes(Date, Visits)) + 
    geom_line() + 
    scale_x_date(format = "%b %d", major =  "1 day")

For me , df1.subtract(df2) was inconsistent. Worked correctly on one dataframe but not on the other . That was because of duplicates . df1.exceptAll(df2) returns a new dataframe with the records from df1 that do not exist in df2 , including any duplicates.

While Mockito doesn't provide that capability, you can achieve the same result using Mockito + the JUnit ReflectionUtils class or the Spring ReflectionTestUtils class. Please see an example below taken from here explaining how to invoke a private method:

ReflectionTestUtils.invokeMethod(student, "saveOrUpdate", "From Unit test");

Complete examples with ReflectionTestUtils and Mockito can be found in the book Mockito for Spring

You can do union or simple list comprehension

[A.add(_) for _ in B]

A would have all the elements of B

You can use pandas.cut:

bins = [0, 1, 5, 10, 25, 50, 100]
df['binned'] = pd.cut(df['percentage'], bins)
print (df)
   percentage     binned
0       46.50   (25, 50]
1       44.20   (25, 50]
2      100.00  (50, 100]
3       42.12   (25, 50]

bins = [0, 1, 5, 10, 25, 50, 100]
labels = [1,2,3,4,5,6]
df['binned'] = pd.cut(df['percentage'], bins=bins, labels=labels)
print (df)
   percentage binned
0       46.50      5
1       44.20      5
2      100.00      6
3       42.12      5

Or numpy.searchsorted:

bins = [0, 1, 5, 10, 25, 50, 100]
df['binned'] = np.searchsorted(bins, df['percentage'].values)
print (df)
   percentage  binned
0       46.50       5
1       44.20       5
2      100.00       6
3       42.12       5

...and then value_counts or groupby and aggregate size:

s = pd.cut(df['percentage'], bins=bins).value_counts()
print (s)
(25, 50]     3
(50, 100]    1
(10, 25]     0
(5, 10]      0
(1, 5]       0
(0, 1]       0
Name: percentage, dtype: int64

s = df.groupby(pd.cut(df['percentage'], bins=bins)).size()
print (s)
percentage
(0, 1]       0
(1, 5]       0
(5, 10]      0
(10, 25]     0
(25, 50]     3
(50, 100]    1
dtype: int64

By default cut return categorical.

Series methods like Series.value_counts() will use all categories, even if some categories are not present in the data, operations in categorical.

You should be able to transfer the Application to another Username. You would need all your old user information to transfer it. The application would remove it's self from old account to new account. Also you could put a limit on how many times you where allowed to transfer it. If you transfer it to the application could expire after a year and force to buy update.

Just a heads up... with Python 2.7, and I believe ever since super() was introduced in version 2.2, you can only call super() if one of the parents inherit from a class that eventually inherits object (new-style classes).

Personally, as for python 2.7 code, I'm going to continue using BaseClassName.__init__(self, args) until I actually get the advantage of using super().

I assume you know that i is the key and that you can get the value via data[i] (and just want a shortcut for this).

ECMAScript5 introduced forEach ^[MDN] for arrays (it seems you have an array):

data.forEach(function(value, index) {

});

The MDN documentation provides a shim for browsers not supporting it.

Of course this does not work for objects, but you can create a similar function for them:

function forEach(object, callback) {
    for(var prop in object) {
        if(object.hasOwnProperty(prop)) {
            callback(prop, object[prop]);
        }
    }
}

Since you tagged the question with jquery, jQuery provides $.each ^[docs] which loops over both, array and object structures.

var rootEle = document.querySelector("html");
var ele = angular.element(rootEle); 

scope() We can fetch the $scope from the element (or its parent) by using the scope() method on the element:

var scope = ele.scope();

injector()

var injector = ele.injector();

With this injector, we can then then instantiate any Angular object inside of our app, such as services, other controllers, or any other object

You can use the "-r" option to set the sender address:

I manged to set the MinDate & the MaxDate programmatically like this :

    final Calendar c = Calendar.getInstance();

    int maxYear = c.get(Calendar.YEAR) - 20; // this year ( 2011 ) - 20 = 1991
    int maxMonth = c.get(Calendar.MONTH);
    int maxDay = c.get(Calendar.DAY_OF_MONTH);

    int minYear = 1960;
    int minMonth = 0; // january
    int minDay = 25;

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.create_account);
        BirthDateDP = (DatePicker) findViewById(R.id.create_account_BirthDate_DatePicker);
        BirthDateDP.init(maxYear - 10, maxMonth, maxDay, new OnDateChangedListener()
        {

        @Override
        public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth)
        {
            if (year < minYear)
                view.updateDate(minYear, minMonth, minDay);

                if (monthOfYear < minMonth && year == minYear)
                view.updateDate(minYear, minMonth, minDay);

                if (dayOfMonth < minDay && year == minYear && monthOfYear == minMonth)
                view.updateDate(minYear, minMonth, minDay);


                if (year > maxYear)
                view.updateDate(maxYear, maxMonth, maxDay);

                if (monthOfYear > maxMonth && year == maxYear)
                view.updateDate(maxYear, maxMonth, maxDay);

                if (dayOfMonth > maxDay && year == maxYear && monthOfYear == maxMonth)
                view.updateDate(maxYear, maxMonth, maxDay);
        }}); // BirthDateDP.init()
    } // activity

it works fine for me, enjoy :)

The HTTPS certificate verification security measure isn't something to be discarded light-heartedly. The Man-in-the-middle attack that it prevents safeguards you from a third party e.g. sipping a virus in or tampering with or stealing your data.

• it will use (since requests v2.4.0) the certifi package instead if it's installed
• In a test environment, you can easily slip a test certificate into certifi as per how do I update root certificates of certifi? . E.g. if you replace its bundle with just your test certificate, you will immediately see it if you forget to undo that when moving to production.

Finally, with today's government-backed global hacking operations like Tailored Access Operations and the Great Firewall of China that target network infrastructure, falling under a MITM attack is more probable than you think.

You get into a difficult situation when it is necessary to understand how scopes, ngRepeat and ngModel with NgModelController work. Also try to use 1.0.3 version. Your example will work a little differently.

You can simply use solution provided by jm-

But if you want to deal with the situation more deeply, you have to understand:

• how AngularJS works;
• scopes have a hierarchical structure;
• ngRepeat creates new scope for every element;
• ngRepeat build cache of items with additional information (hashKey); on each watch call for every new item (that is not in the cache) ngRepeat constructs new scope, DOM element, etc. More detailed description.
• from 1.0.3 ngModelController rerenders inputs with actual model values.

How your example "Binding to each element directly" works for AngularJS 1.0.3:

• you enter letter 'f' into input;
• ngModelController changes model for item scope (names array is not changed) => name == 'Samf', names == ['Sam', 'Harry', 'Sally'];
• $digest loop is started;
• ngRepeat replaces model value from item scope ('Samf') by value from unchanged names array ('Sam');
• ngModelController rerenders input with actual model value ('Sam').

How your example "Indexing into the array" works:

• you enter letter 'f' into input;
• ngModelController changes item in names array => `names == ['Samf', 'Harry', 'Sally'];
• $digest loop is started;
• ngRepeat can't find 'Samf' in cache;
• ngRepeat creates new scope, adds new div element with new input (that is why the input field loses focus - old div with old input is replaced by new div with new input);
• new values for new DOM elements are rendered.

Also, you can try to use AngularJS Batarang and see how changes $id of the scope of div with input in which you enter.

try this code

input[type="checkbox"] {
    -moz-appearance: checkbox;
    -webkit-appearance: checkbox;
    margin-left:3px;
    border:0;
    vertical-align: middle;
    top: -1px;
    bottom: 1px;
    *overflow: hidden;
    box-sizing: border-box; /* 1 */
    *height: 13px; /* Removes excess padding in IE 7 */
    *width: 13px;
    background: #fff;
}

This is quite simple.

Assuming the data is stored in a column called A in a table called T, you can use

select A, count(A) from T group by A

I would advise against restricting the SecurityProtocol to TLS 1.1.

The recommended solution is to use

System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls

Another option is add the following Registry key:

Key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319 
Value: SchUseStrongCrypto 

It is worth noting that .NET 4.6 will use the correct protocol by default and does not require either solution.

I also like itertuples()

for row in df.itertuples():
    print(row.A)
    print(row.Index)

since row is a named tuples, if you meant to access values on each row this should be MUCH faster

speed run :

df = pd.DataFrame([x for x in range(1000*1000)], columns=['A'])
st=time.time()
for index, row in df.iterrows():
    row.A
print(time.time()-st)
45.05799984931946

st=time.time()
for row in df.itertuples():
    row.A
print(time.time() - st)
0.48400020599365234

What I suggest for now is to create symlinks in a folder, since VSCode isn't supporting that feature.

First, make a folder called whatever you'd like it to be.

$ mkdir random_project_folder
$ cd random_project_folder
$ ln -s /path/to/folder1/you/want/to/open folder1
$ ln -s /path/to/folder2/you/want/to/open folder2
$ ln -s /path/to/folder3/you/want/to/open folder3
$ code .

And you'll see your folders in the same VSCode window.

Change the Target version to new updates you have. Otherwise, change what SDK version you have in the Android manifest file.

android:minSdkVersion="8"
android:targetSdkVersion="18"

secure - This attribute tells the browser to only send the cookie if the request is being sent over a secure channel such as HTTPS. This will help protect the cookie from being passed over unencrypted requests. If the application can be accessed over both HTTP and HTTPS, then there is the potential that the cookie can be sent in clear text.

Use the flex-grow property to make a flex item consume free space on the main axis.

This property will expand the item as much as possible, adjusting the length to dynamic environments, such as screen re-sizing or the addition / removal of other items.

A common example is flex-grow: 1 or, using the shorthand property, flex: 1.

Hence, instead of width: 96% on your div, use flex: 1.

You wrote:

So at the moment, it's set to 96% which looks OK until you really squash the screen - then the right hand div gets a bit starved of the space it needs.

The squashing of the fixed-width div is related to another flex property: flex-shrink

By default, flex items are set to flex-shrink: 1 which enables them to shrink in order to prevent overflow of the container.

To disable this feature use flex-shrink: 0.

For more details see The flex-shrink factor section in the answer here:

• What are the differences between flex-basis and width?

Learn more about flex alignment along the main axis here:

• In CSS Flexbox, why are there no "justify-items" and "justify-self" properties?

The thing i don't like about iValidate is it seems to only run AFTER all other validation.
Additionally, at least in our site, it would run again during a save attempt. I would suggest you simply create a function and place all your validation code in that. Alternately for websites, you could have your "special" validation in the controller after the model is created. Example:

 public ActionResult Update([DataSourceRequest] DataSourceRequest request, [Bind(Exclude = "Terminal")] Driver driver)
    {

        if (db.Drivers.Where(m => m.IDNumber == driver.IDNumber && m.ID != driver.ID).Any())
        {
            ModelState.AddModelError("Update", string.Format("ID # '{0}' is already in use", driver.IDNumber));
        }
        if (db.Drivers.Where(d => d.CarrierID == driver.CarrierID
                                && d.FirstName.Equals(driver.FirstName, StringComparison.CurrentCultureIgnoreCase)
                                && d.LastName.Equals(driver.LastName, StringComparison.CurrentCultureIgnoreCase)
                                && (driver.ID == 0 || d.ID != driver.ID)).Any())
        {
            ModelState.AddModelError("Update", "Driver already exists for this carrier");
        }

        if (ModelState.IsValid)
        {
            try
            {

If I understand you right, you can do this:

<img src="image.png" style="background-color:red;" />

In fact, you can even apply a whole background-image to the image, resulting in two "layers" without the need for multi-background support in the browser ;)

the time signal is not built into network antennas: you have to use the NTP protocol in order to retrieve the time on a ntp server. there are plenty of ntp clients, available as standalone executables or libraries.

the gps signal does indeed include a precise time signal, which is available with any "fix".

however, if nor the network, nor the gps are available, your only choice is to resort on the time of the phone... your best solution would be to use a system wide setting to synchronize automatically the phone time to the gps or ntp time, then always use the time of the phone.

note that the phone time, if synchronized regularly, should not differ much from the gps or ntp time. also note that forcing a user to synchronize its time may be intrusive, you 'd better ask your user if he accepts synchronizing. at last, are you sure you absolutely need a time that precise ?

 String str="10,692,467,440,017.120".replaceAll(",","");

Default migration generator does not handle default values (column modifiers are supported but do not include default or null), but you could create your own generator.

You can also manually update the migration file prior to running rake db:migrate by adding the options to add_column:

add_column :tweet, :retweets_count, :integer, :null => false, :default => 0

... and read Rails API

Your null pointer exception seems to be on this line:

String url = intent.getExtras().getString("userurl");

because intent.getExtras() returns null when the intent doesn't have any extras.

You have to realize that this piece of code:

Intent Main = new Intent(this, ToClass.class);
Main.putExtra("userurl", url);
startActivity(Main);

doesn't start the activity you wrote in Main.java, it will attempt to start an activity called ToClass and if that doesn't exist, your app crashes.

Also, there is no such thing as "android.intent.action.start" so the manifest should look more like:

<activity android:name=".start" android:label="@string/app_name">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>
<activity android:name= ".Main">
</activity>

I hope this fixes some of the issues you are encountering but I strongly suggest you check out some "getting started" tutorials for android development and build up from there.

Some special characters give this type of error, so use

$query="INSERT INTO `tablename` (`name`, `email`)
VALUES
('$_POST[name]','$_POST[email]')";

Array push and pop method can be used for sequence of promises. You can also push new promises when you need additional data. This is the code, I will use in React Infinite loader to load sequence of pages.

var promises = [Promise.resolve()];_x000D_
_x000D_
function methodThatReturnsAPromise(page) {_x000D_
 return new Promise((resolve, reject) => {_x000D_
  setTimeout(() => {_x000D_
   console.log(`Resolve-${page}! ${new Date()} `);_x000D_
   resolve();_x000D_
  }, 1000);_x000D_
 });_x000D_
}_x000D_
_x000D_
function pushPromise(page) {_x000D_
 promises.push(promises.pop().then(function () {_x000D_
  return methodThatReturnsAPromise(page)_x000D_
 }));_x000D_
}_x000D_
_x000D_
pushPromise(1);_x000D_
pushPromise(2);_x000D_
pushPromise(3);

There is no solution for this within the .net framework.

One need to set NavigateItem checked true whenever item in NavigateView is clicked

//listen for navigation events
NavigationView navigationView = (NavigationView)findViewById(R.id.navigation);
navigationView.setNavigationItemSelectedListener(this);
// select the correct nav menu item
navigationView.getMenu().findItem(mNavItemId).setChecked(true);

Add NavigationItemSelectedListener on NavigationView

  @Override
  public boolean onNavigationItemSelected(final MenuItem menuItem) {
    // update highlighted item in the navigation menu
    menuItem.setChecked(true);
    mNavItemId = menuItem.getItemId();

    // allow some time after closing the drawer before performing real navigation
    // so the user can see what is happening
    mDrawerLayout.closeDrawer(GravityCompat.START);
    mDrawerActionHandler.postDelayed(new Runnable() {
      @Override
      public void run() {
        navigate(menuItem.getItemId());
      }
    }, DRAWER_CLOSE_DELAY_MS);
    return true;
  }

I'm not sure about this, but give it a shot.

In your strings.xml define:

<string-array name="array_name">
<item>Array Item One</item>
<item>Array Item Two</item>
<item>Array Item Three</item>
</string-array>

In your layout:

<Spinner 
        android:id="@+id/spinner"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:drawSelectorOnTop="true"
        android:entries="@array/array_name"
    />

I've heard this doesn't always work on the designer, but it compiles fine.

1:n means 'one-to-many'; you have two tables, and each row of table A may be referenced by any number of rows in table B, but each row in table B can only reference one row in table A (or none at all).

n:m (or n:n) means 'many-to-many'; each row in table A can reference many rows in table B, and each row in table B can reference many rows in table A.

A 1:n relationship is typically modelled using a simple foreign key - one column in table A references a similar column in table B, typically the primary key. Since the primary key uniquely identifies exactly one row, this row can be referenced by many rows in table A, but each row in table A can only reference one row in table B.

A n:m relationship cannot be done this way; a common solution is to use a link table that contains two foreign key columns, one for each table it links. For each reference between table A and table B, one row is inserted into the link table, containing the IDs of the corresponding rows.

This works for me in Kotlin:

when(list.get(0)).thenThrow(new ArrayIndexOutOfBoundsException());

Note : Throw any defined exception other than Exception()

The children property returns an array of elements, like so:

parent = document.querySelector('.parent');
children = parent.children; // [<div class="child1">]

There are alternatives to querySelector, like document.getElementsByClassName('parent')[0] if you so desire.

Edit: Now that I think about it, you could just use querySelectorAll to get decendents of parent having a class name of child1:

children = document.querySelectorAll('.parent .child1');

The difference between qS and qSA is that the latter returns all elements matching the selector, while the former only returns the first such element.

I did like this :

public static class JsonExtension
{
    public static string ToJson(this object value)
    {
        var settings = new JsonSerializerSettings
        {
            ContractResolver = new CamelCasePropertyNamesContractResolver(),
            NullValueHandling = NullValueHandling.Ignore,
            ReferenceLoopHandling = ReferenceLoopHandling.Serialize
        };
        return JsonConvert.SerializeObject(value, settings);
    }
}

this a simple extension method in MVC core , it's going to give the ToJson() ability to every object in your project , In my opinion in a MVC project most of object should have the ability to become json ,off course it depends :)

Depending on the type of your variable, one of abs(int), labs(long), llabs(long long), imaxabs(intmax_t), fabsf(float), fabs(double), or fabsl(long double).

Those functions are all part of the C standard library, and so are present both in Objective-C and plain C (and are generally available in C++ programs too.)

(Alas, there is no habs(short) function. Or scabs(signed char) for that matter...)

Apple's and GNU's Objective-C headers also include an ABS() macro which is type-agnostic. I don't recommend using ABS() however as it is not guaranteed to be side-effect-safe. For instance, ABS(a++) will have an undefined result.

If you're using C++ or Objective-C++, you can bring in the <cmath> header and use std::abs(), which is templated for all the standard integer and floating-point types.

1. Create nuget.config in same directory where your solution file is, with following content:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <config>
    <add key="repositoryPath" value="packages" />
  </config>
</configuration>

'packages' will be the folder where all packages will be restored.

2. Close Visual studio solution and open it again.

CSS transformations create a new stacking context and containing block, as described in the spec. In plain English, this means that fixed position elements with a transformation applied to them will act more like absolutely positioned elements, and z-index values are likely to get screwed with.

If you take a look at this demo, you'll see what I mean. The second div has a transformation applied to it, meaning that it creates a new stacking context, and the pseudo elements are stacked on top rather than below.

So basically, don't do that. Apply a 3D transformation only when you need the optimization. -webkit-font-smoothing: antialiased; is another way to tap into 3D acceleration without creating these problems, but it only works in Safari.

How to implement:

import 'package:intl/intl.dart';

getCustomFormattedDateTime(String givenDateTime, String dateFormat) {
    // dateFormat = 'MM/dd/yy';
    final DateTime docDateTime = DateTime.parse(givenDateTime);
    return DateFormat(dateFormat).format(docDateTime);
}

How to call:

getCustomFormattedDateTime('2021-02-15T18:42:49.608466Z', 'MM/dd/yy');

Result:

02/15/21

Above code solved my problem. I hope, this will also help you. Thanks for asking this question.

You can do something like this in awk:

awk '{ print $NF }'

Edit: To avoid empty line :

awk 'NF{ print $NF }'

@rvighne solution works well, but as identified in the comments ParentElement and ClassList both have compatibility issues. To make it more compatible, I have used:

function findAncestor (el, cls) {
    while ((el = el.parentNode) && el.className.indexOf(cls) < 0);
    return el;
}

• parentNode property instead of the parentElement property
• indexOf method on the className property instead of the contains method on the classList property.

Of course, indexOf is simply looking for the presence of that string, it does not care if it is the whole string or not. So if you had another element with class 'ancestor-type' it would still return as having found 'ancestor', if this is a problem for you, perhaps you can use regexp to find an exact match.

According to Android platform developer Dianne Hackborn in this discussion group post, Dialogs set their Window's top level layout width and height to WRAP_CONTENT. To make the Dialog bigger, you can set those parameters to MATCH_PARENT.

Demo code:

    AlertDialog.Builder adb = new AlertDialog.Builder(this);
    Dialog d = adb.setView(new View(this)).create();
    // (That new View is just there to have something inside the dialog that can grow big enough to cover the whole screen.)

    WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
    lp.copyFrom(d.getWindow().getAttributes());
    lp.width = WindowManager.LayoutParams.MATCH_PARENT;
    lp.height = WindowManager.LayoutParams.MATCH_PARENT;
    d.show();
    d.getWindow().setAttributes(lp);

Note that the attributes are set after the Dialog is shown. The system is finicky about when they are set. (I guess that the layout engine must set them the first time the dialog is shown, or something.)

It would be better to do this by extending Theme.Dialog, then you wouldn't have to play a guessing game about when to call setAttributes. (Although it's a bit more work to have the dialog automatically adopt an appropriate light or dark theme, or the Honeycomb Holo theme. That can be done according to http://developer.android.com/guide/topics/ui/themes.html#SelectATheme )

Since the .length property is special for arrays in javascript you can simply say

obj.length === +obj.length // true if obj is an array

Underscorejs and several other libraries use this short and simple trick.

There's no need to group in that subquery... a where clause would suffice:

SELECT * FROM tblpm n
WHERE date_updated=(SELECT MAX(date_updated)
    FROM tblpm WHERE control_number=n.control_number)

Also, do you have an index on the 'date_updated' column? That would certainly help.

You can use IPython.display.clear_output to clear the output of a cell.

from IPython.display import clear_output

for i in range(10):
    clear_output(wait=True)
    print("Hello World!")

At the end of this loop you will only see one Hello World!.

Without a code example it's not easy to give you working code. Probably buffering the latest n events is a good strategy. Whenever the buffer changes you can clear the cell's output and print the buffer again.

if you use Windows 10, this is the directory:

C:\Users<UserName>\AppData\Local\

+

<ProjectName.exe_Url_somedata>\1.0.0.0<filename.config>

I'm using following code from Application_Start

String baseUrl = Path.GetDirectoryName(HttpContext.Current.Request.Url.OriginalString);

SWIFT 4:

self.view.endEditing(true)

or

Set text field's delegate to current viewcontroller and then:

func textFieldShouldReturn(_ textField: UITextField) -> Bool {

    textField.resignFirstResponder()

    return true

}

Objective-C:

[self.view endEditing:YES];

or

Set text field's delegate to current viewcontroller and then:

- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
    [textField resignFirstResponder];

    return YES;
}

This is a workaround (for me: I don't use awk very often):

Display the first row of the file containing the data, replace all pipes with newlines and then count the lines:

$ head -1 stores.dat | tr '|' '\n' | wc -l

Try this basic example for better understanding of race condition:

When you use : scene.remove(object); The object is removed from the scene, but the collision with it is still enabled !

To remove also the collsion with the object, you can use that (for an array) : objectsArray.splice(i, 1);

Example :

for (var i = 0; i < objectsArray.length; i++) {
//::: each object ::://
var object = objectsArray[i]; 
//::: remove all objects from the scene ::://
scene.remove(object); 
//::: remove all objects from the array ::://
objectsArray.splice(i, 1); 

}

You won't face any terrible consequence, just the history will look kind of confusing.

You could change the commit message by doing

git commit --amend
git push --force-with-lease # (as opposed to --force, it doesn't overwrite others' work)

BUT this will override the remote history with yours, meaning that if anybody pulled that repo in the meanwhile, this person is going to be very mad at you...

Just do it if you are the only person accessing the repo.

EditText dummy = ... 

// android.view.View.OnFocusChangeListener
dummy.setOnFocusChangeListener(new OnFocusChangeListener(){
    public void onFocusChange(View v, boolean hasFocus){
        if (hasFocus) && (isDummyText())
            ((EditText)v).selectAll();
    }
});

Here is a function for checking the exit status of the last command, showing error and terminate the script.

or_exit() {
    local exit_status=$?
    local message=$*

    if [ "$exit_status" -gt 0 ]
    then
        echo "$(date '+%F %T') [$(basename "$0" .sh)] [ERROR] $message" >&2
        exit "$exit_status"
    fi
}

Usage:

gzip "$data_dir"
    or_exit "Cannot gzip $data_dir"

rm -rf "$junk"
    or_exit Cannot remove $junk folder

The function prints out the script name and the date in order to be useful when the script is called from crontab and logs the errors.

Jason Bunting's answer gave me enough of a clue to find what I needed:

<<Object instance>>.constructor.name

So, for example, in the following piece of code:

function MyObject() {}
var myInstance = new MyObject();

myInstance.constructor.name would return "MyObject".

All the workaround mentioned above may work or may not work, in most cases it will not work. I have given the solution here

Currently I am working on Angular and Web API(.net Core) and came across CORS issue explained below

The solution provided above will always work. With 'OPTIONS' request it is really necessary to enable 'Anonymous Authentication'. With the solution mentioned here you don't have to do all the steps mentioned above, like IIS settings.

Anyways someone marked my above post as duplicate with this post, but I can see that this post is only to enable CORS in ASP.net Core, but my post is related to, Enabling and implementing CORS in ASP.net Core and Angular.

length and dbms_lob.getlength return the number of characters when applied to a CLOB (Character LOB). When applied to a BLOB (Binary LOB), dbms_lob.getlength will return the number of bytes, which may differ from the number of characters in a multi-byte character set.

As the documentation doesn't specify what happens when you apply length on a BLOB, I would advise against using it in that case. If you want the number of bytes in a BLOB, use dbms_lob.getlength.

Ahah! Checkout the previous commit, then checkout the master.

git checkout HEAD^
git checkout -f master

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

window.WindowStyle = WindowStyle.None;
window.ResizeMode = ResizeMode.NoResize;
window.Left = 0;
window.Top = 0;
window.Width = SystemParameters.VirtualScreenWidth;
window.Height = SystemParameters.VirtualScreenHeight;
window.Topmost = true;

Works with multiple screens

Set a local value with the observer

...also, don't forget to initialize the value with dummy data to avoid uninitialized errors.

export class ModelService {
    constructor() {
      this.mode = new Model();

      this._http.get('/api/v1/cats')
      .map(res => res.json())
      .subscribe(
        json => {
          this.model = new Model(json);
        },
        error => console.log(error);
      );
    }
}

This assumes Model, is a data model representing the structure of your data.

Model with no parameters should create a new instance with all values initialized (but empty). That way, if the template renders before the data is received it won't throw an error.

Ideally, if you want to persist the data to avoid unnecessary http requests you should put this in an object that has its own observer that you can subscribe to.

ios will always tries to take the best image, but will fall back to other options .. so if you only have normal images in the app and it needs @2x images it will use the normal images.

if you only put @2x in the project and you open the app on a normal device it will scale the images down to display.

if you target ios7 and ios8 devices and want best quality you would need @2x and @3x for phone and normal and @2x for ipad assets, since there is no non retina phone left and no @3x ipad.

maybe it is better to create the assets in the app from vector graphic... check http://mattgemmell.com/using-pdf-images-in-ios-apps/

Populating a list is easier than an array. For arrays, you need to know the exact length of data, but for lists, data size can be any. And, you can convert a list into an array.

List<URLDTO> urls = new List<URLDTO>();

urls.Add(new URLDTO() {
    key = "wiki",
    url = "https://...",
});

urls.Add(new URLDTO()
{
    key = "url",
    url = "http://...",
});

urls.Add(new URLDTO()
{
    key = "dir",
    url = "https://...",
});

// convert a list into an array: URLDTO[]
return urls.ToArray();

Ok, finally found the solution.

Probably due to lack of experience with ReactJS and web development...

    var Task = React.createClass({
    render: function() {
      var percentage = this.props.children + '%';
      ....
        <div className="ui-progressbar-value ui-widget-header ui-corner-left" style={{width : percentage}}/>
      ...

I created the percentage variable outside in the render function.

Here's my answer for those that are Googling:

CSS:

.column {
    float: left;
    width: 50%;
}

/* Clear floats after the columns */
.container:after {
    content: "";
    display: table;
    clear: both;
}

Here's the HTML:

<div class="container">
    <div class="column"></div>
    <div class="column"></div>
</div>

Maximum number of elements of an array is (2^31)-1 or 2 147 483 647

This is a circular dependency issue. Golang programs must be acyclic. In Golang cyclic imports are not allowed (That is its import graph must not contain any loops)

Lets say your project go-circular-dependency have 2 packages "package one" & it has "one.go" & "package two" & it has "two.go" So your project structure is as follows

+--go-circular-dependency    
      +--one    
         +-one.go
      +--two        
         +-two.go

This issue occurs when you try to do something like following.

Step 1 - In one.go you import package two (Following is one.go)

package one

import (
    "go-circular-dependency/two"
)

//AddOne is
func AddOne() int {
    a := two.Multiplier()
    return a + 1
}

Step 2 - In two.go you import package one (Following is two.go)

package two

import (
    "fmt"
    "go-circular-dependency/one"
)

//Multiplier is going to be used in package one
func Multiplier() int {
    return 2
}

//Total is
func Total() {
    //import AddOne from "package one"
    x := one.AddOne()
    fmt.Println(x)
}

In Step 2, you will receive an error "can't load package: import cycle not allowed" (This is called "Circular Dependency" error)

Technically speaking this is bad design decision and you should avoid this as much as possible, but you can "Break Circular Dependencies via implicit interfaces" (I personally don't recommend, and highly discourage this practise, because by design Go programs must be acyclic)

Try to keep your import dependency shallow. When the dependency graph becomes deeper (i.e package x imports y, y imports z, z imports x) then circular dependencies become more likely.

Sometimes code repetition is not bad idea, which is exactly opposite of DRY (don't repeat yourself)

So in Step 2 that is in two.go you should not import package one. Instead in two.go you should actually replicate the functionality of AddOne() written in one.go as follows.

package two

import (
    "fmt"
)

//Multiplier is going to be used in package one
func Multiplier() int {
    return 2
}

//Total is
func Total() {
    // x := one.AddOne()
    x := Multiplier() + 1
    fmt.Println(x)
}

Sure. Just generate a color using random RGB values. Like:

public Color randomColor()
{
  Random random=new Random(); // Probably really put this somewhere where it gets executed only once
  int red=random.nextInt(256);
  int green=random.nextInt(256);
  int blue=random.nextInt(256);
  return new Color(red, green, blue);
}

You might want to vary up the generation of the random numbers if you don't like the colors it comes up with. I'd guess these will tend to be fairly dark.

If you want to update a single gem to a specific version:

1. change the version of the gem in the Gemfile
2. bundle update

> ruby -v
ruby 2.6.5p114 (2019-10-01 revision 67812) [x86_64-darwin19]

If you have used them in C, then they are almost same as were in C.

From the manpage of fopen() function : -

• r+ : - Open for reading and writing. The stream is positioned at the beginning of the file.
  
  
• a+ : - Open for reading and writing. The file is created if it does not exist. The stream is positioned at the end of the file. Subse- quent writes to the file will always end up at the then current end of file, irrespective of any intervening fseek(3) or similar.

For default tooltip this can be used -

System.Windows.Forms.ToolTip ToolTip1 = new System.Windows.Forms.ToolTip();
ToolTip1.SetToolTip(this.textBox1, "Hello world");

A customized tooltip can also be used in case if formatting is required for tooltip message. This can be created by custom formatting the form and use it as tooltip dialog on mouse hover event of the control. Please check following link for more details -

http://newapputil.blogspot.in/2015/08/create-custom-tooltip-dialog-from-form.html

Instead of parsing it manually it's better to use pathinfo function:

$path_parts = pathinfo($value);
$extension = strtolower($path_parts['extension']);
$fileName = $path_parts['filename'];

And using the joiner from http://jinja.pocoo.org/docs/dev/templates/#joiner

{% set comma = joiner(",") %}
{% for user in userlist %}
    {{ comma() }}<a href="/profile/{{ user }}/">{{ user }}</a>
{% endfor %}  

It's made for this exact purpose. Normally a join or a check of forloop.last would suffice for a single list, but for multiple groups of things it's useful.

A more complex example on why you would use it.

{% set pipe = joiner("|") %}
{% if categories %} {{ pipe() }}
    Categories: {{ categories|join(", ") }}
{% endif %}
{% if author %} {{ pipe() }}
    Author: {{ author() }}
{% endif %}
{% if can_edit %} {{ pipe() }}
    <a href="?action=edit">Edit</a>
{% endif %}

I was having the same issue and tried all of the solutions on this page but none of them did the trick.

What finally worked was adding the universe repo to my repo list. To do that run the following command

sudo add-apt-repository universe

After running the above command I was able to run

sudo apt install openjdk-8-jre

without an issue and the package was installed.

Hope this helps someone.

In DB2, using single quotes instead of your double quotes will work. So that could translate the same in Oracle..

SELECT CustomerName AS Customer, '' AS Contact 
FROM Customers;

While the OP may be working on a nix platform this answer could help non-nix platforms. I have not experienced the shebang approach work in Microsoft Windows.

Rephrased: The shebang line answers your question of "within my script" but I believe only for Unix-like platforms. Even though it is the Unix shell, outside the script, that actually interprets the shebang line to determine which version of Python interpreter to call. I am not sure, but I believe that solution does not solve the problem for Microsoft Windows platform users.

In the Microsoft Windows world, the simplify the way to run a specific Python version, without environment variables setup specifically for each specific version of Python installed, is just by prefixing the python.exe with the path you want to run it from, such as C:\Python25\python.exe mymodule.py or D:\Python27\python.exe mymodule.py

However you'd need to consider the PYTHONPATH and other PYTHON... environment variables that would point to the wrong version of Python libraries.

For example, you might run: C:\Python2.5.2\python.exe mymodule

Yet, the environment variables may point to the wrong version as such:

PYTHONPATH = D:\Python27

PYTHONLIB = D:\Python27\lib

Loads of horrible fun!

So a non-virtualenv way, in Windows, would be to use a batch file that sets up the environment and calls a specific Python executable via prefixing the python.exe with the path it resides in. This way has additional details you'll have to manage though; such as using command line arguments for either of the "start" or "cmd.exe" command to "save and replace the "console" environment" if you want the console to stick around after the application exits.

Your question leads me to believe you have several Python modules, each expecting a certain version of Python. This might be solvable "within" the script by having a launching module which uses the subprocess module. Instead of calling mymodule.py you would call a module that calls your module; perhaps launch_mymodule.py

launch_mymodule.py

import sys
import subprocess
if sys.argv[2] == '272':
  env272 = {
    'PYTHONPATH': 'blabla',
    'PYTHONLIB': 'blabla', }
  launch272 = subprocess.Popen('D:\\Python272\\python.exe mymodule.py', env=env272)

if sys.argv[1] == '252'
  env252 = {
    'PYTHONPATH': 'blabla',
    'PYTHONLIB': 'blabla', }
  launch252 = subprocess.Popen('C:\\Python252\\python.exe mymodule.py', env=env252)

I have not tested this.

In short, services set to Automatic will start during the boot process, while services set to start as Delayed will start shortly after boot.

Starting your service Delayed improves the boot performance of your server and has security benefits which are outlined in the article Adriano linked to in the comments.

Update: "shortly after boot" is actually 2 minutes after the last "automatic" service has started, by default. This can be configured by a registry key, according to Windows Internals and other sources (3,4).

The registry keys of interest (At least in some versions of windows) are:

• HKLM\SYSTEM\CurrentControlSet\services\<service name>\DelayedAutostart will have the value 1 if delayed, 0 if not.
• HKLM\SYSTEM\CurrentControlSet\services\AutoStartDelay or HKLM\SYSTEM\CurrentControlSet\Control\AutoStartDelay (on Windows 10): decimal number of seconds to wait, may need to create this one. Applies globally to all Delayed services.

When you are using Vue directives, the expressions are evaluated in the context of Vue, so you don't need to wrap things in {}.

@click is just shorthand for v-on:click directive so the same rules apply.

In your case, simply use @click="addToCount(item.contactID)"

To do this, I had to come up with an intermediate data structure:

class KeyDataPoint {
    String key;
    DateTime timestamp;
    Number data;
    // obvious constructor and getters
}

With this in place, the approach is to "flatten" each MultiDataPoint into a list of (timestamp, key, data) triples and stream together all such triples from the list of MultiDataPoint.

Then, we apply a groupingBy operation on the string key in order to gather the data for each key together. Note that a simple groupingBy would result in a map from each string key to a list of the corresponding KeyDataPoint triples. We don't want the triples; we want DataPoint instances, which are (timestamp, data) pairs. To do this we apply a "downstream" collector of the groupingBy which is a mapping operation that constructs a new DataPoint by getting the right values from the KeyDataPoint triple. The downstream collector of the mapping operation is simply toList which collects the DataPoint objects of the same group into a list.

Now we have a Map<String, List<DataPoint>> and we want to convert it to a collection of DataSet objects. We simply stream out the map entries and construct DataSet objects, collect them into a list, and return it.

The code ends up looking like this:

Collection<DataSet> convertMultiDataPointToDataSet(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .flatMap(mdp -> mdp.getData().entrySet().stream()
                           .map(e -> new KeyDataPoint(e.getKey(), mdp.getTimestamp(), e.getValue())))
        .collect(groupingBy(KeyDataPoint::getKey,
                    mapping(kdp -> new DataPoint(kdp.getTimestamp(), kdp.getData()), toList())))
        .entrySet().stream()
        .map(e -> new DataSet(e.getKey(), e.getValue()))
        .collect(toList());
}

I took some liberties with constructors and getters, but I think they should be obvious.

Backbone.js is basically an uber-light framework that allows you to structure your Javascript code in an MVC (Model, View, Controller) fashion where...

Model is part of your code that retrieves and populates the data,

View is the HTML representation of this model (views change as models change, etc.)

and optional Controller that in this case allows you to save the state of your Javascript application via a hashbang URL, for example: http://twitter.com/#search?q=backbone.js

Some pros that I discovered with Backbone:

• No more Javascript Spaghetti: code is organized and broken down into semantically meaningful .js files which are later combined using JAMMIT

• No more jQuery.data(bla, bla): no need to store data in DOM, store data in models instead

• event binding just works

• extremely useful Underscore utility library

• backbone.js code is well documented and a great read. Opened my eyes to a number of JS code techniques.

Cons:

• Took me a while to wrap my head around it and figure out how to apply it to my code, but I'm a Javascript newbie.

Here is a set of great tutorials on using Backbone with Rails as the back-end:

p.s. There is also this wonderful Collection class that lets you deal with collections of models and mimic nested models, but I don't want to confuse you from the start.

Forget float, margin and html 3/5. The mail is very obsolete. You need do all with table. One line = one table. You need margin or padding ? Do another column.

Codepen

Example : i need one line with 1 One Picture of 40*40 2 One margin of 10 px 3 One text of 400px

I start my line :

<table style=" background-repeat:no-repeat; width:450px;margin:0;" cellpadding="0" cellspacing="0" border="0">
   <tr style="height:40px; width:450px; margin:0;">
     <td style="height:40px; width:40px; margin:0;">
        <img src="" style="width=40px;height40;margin:0;display:block"
     </td>
     <td style="height:40px; width:10px; margin:0;">        
     </td>
     <td style="height:40px; width:400px; margin:0;">
     <p style=" margin:0;"> my text   </p>
     </td>
   </tr>
</table>

you can write events on elements like chain,

$(element).on('click',function(){
   //action on click
}).on('mouseup',function(){
   //action on mouseup (just before click event)
});

i've used it for removing cart items. same object, doing some action, after another action

You can try this code:

public void itemClicked(View v) {
 //code to check if this checkbox is checked!
 if(((Checkbox)v).isChecked()){
   // code inside if
 }
}

My problem was not resolved with this procedure

FirebaseApp.initializeApp(this); 

So I tried something else and now my firebase has been successfully initialized. Try adding following in app module.gradle

BuildScript{
dependencies {..
classpath : "com.google.firebase:firebase-plugins:1.1.5"
    ..}
}

dependencies {...
implementation : "com.google.firebase:firebase-perf:16.1.0"
implementation : "com.google.firebase:firebase-core:16.0.3"
..}

Here is a jQuery handler that can be used to stop enter submits, and also stop backspace key -> back. The (keyCode: selectorString) pairs in the "keyStop" object are used to match nodes that shouldn't fire their default action.

Remember that the web should be an accessible place, and this is breaking keyboard users' expectations. That said, in my case the web application I am working on doesn't like the back button anyway, so disabling its key shortcut is OK. The "should enter -> submit" discussion is important, but not related to the actual question asked.

Here is the code, up to you to think about accessibility and why you would actually want to do this!

$(function(){
 var keyStop = {
   8: ":not(input:text, textarea, input:file, input:password)", // stop backspace = back
   13: "input:text, input:password", // stop enter = submit 

   end: null
 };
 $(document).bind("keydown", function(event){
  var selector = keyStop[event.which];

  if(selector !== undefined && $(event.target).is(selector)) {
      event.preventDefault(); //stop event
  }
  return true;
 });
});

WMI is the way to do this.

Get-WmiObject -Query "Select StartMode From Win32_Service Where Name='winmgmt'"

Or

Get-WmiObject -Class Win32_Service -Property StartMode -Filter "Name='Winmgmt'"

Adding this just as an addition to @jimt's excellent answer:

one common way to define it all at initialization time is using an anonymous struct:

var opts = []struct {
    shortnm      byte
    longnm, help string
    needArg      bool
}{
    {'a', "multiple", "Usage for a", false},
    {
        shortnm: 'b',
        longnm:  "b-option",
        needArg: false,
        help:    "Usage for b",
    },
}

This is commonly used for testing as well to define few test cases and loop through them.

The answer comes from the javadoc of ZoneId (emphasis mine) ...

A ZoneId is used to identify the rules used to convert between an Instant and a LocalDateTime. There are two distinct types of ID:

• Fixed offsets - a fully resolved offset from UTC/Greenwich, that uses the same offset for all local date-times
• Geographical regions - an area where a specific set of rules for finding the offset from UTC/Greenwich apply

Most fixed offsets are represented by ZoneOffset. Calling normalized() on any ZoneId will ensure that a fixed offset ID will be represented as a ZoneOffset.

... and from the javadoc of ZoneId#of (emphasis mine):

This method parses the ID producing a ZoneId or ZoneOffset. A ZoneOffset is returned if the ID is 'Z', or starts with '+' or '-'.

The argument id is specified as "UTC", therefore it will return a ZoneId with an offset, which also presented in the string form:

System.out.println(now.withZoneSameInstant(ZoneOffset.UTC));
System.out.println(now.withZoneSameInstant(ZoneId.of("UTC")));

Outputs:

2017-03-10T08:06:28.045Z
2017-03-10T08:06:28.045Z[UTC]

As you use the equals method for comparison, you check for object equivalence. Because of the described difference, the result of the evaluation is false.

When the normalized() method is used as proposed in the documentation, the comparison using equals will return true, as normalized() will return the corresponding ZoneOffset:

Normalizes the time-zone ID, returning a ZoneOffset where possible.

now.withZoneSameInstant(ZoneOffset.UTC)
    .equals(now.withZoneSameInstant(ZoneId.of("UTC").normalized())); // true

As the documentation states, if you use "Z" or "+0" as input id, of will return the ZoneOffset directly and there is no need to call normalized():

now.withZoneSameInstant(ZoneOffset.UTC).equals(now.withZoneSameInstant(ZoneId.of("Z"))); //true
now.withZoneSameInstant(ZoneOffset.UTC).equals(now.withZoneSameInstant(ZoneId.of("+0"))); //true

To check if they store the same date time, you can use the isEqual method instead:

now.withZoneSameInstant(ZoneOffset.UTC)
    .isEqual(now.withZoneSameInstant(ZoneId.of("UTC"))); // true

Sample

System.out.println("equals - ZoneId.of(\"UTC\"): " + nowZoneOffset
        .equals(now.withZoneSameInstant(ZoneId.of("UTC"))));
System.out.println("equals - ZoneId.of(\"UTC\").normalized(): " + nowZoneOffset
        .equals(now.withZoneSameInstant(ZoneId.of("UTC").normalized())));
System.out.println("equals - ZoneId.of(\"Z\"): " + nowZoneOffset
        .equals(now.withZoneSameInstant(ZoneId.of("Z"))));
System.out.println("equals - ZoneId.of(\"+0\"): " + nowZoneOffset
        .equals(now.withZoneSameInstant(ZoneId.of("+0"))));
System.out.println("isEqual - ZoneId.of(\"UTC\"): "+ nowZoneOffset
        .isEqual(now.withZoneSameInstant(ZoneId.of("UTC"))));

Output:

equals - ZoneId.of("UTC"): false
equals - ZoneId.of("UTC").normalized(): true
equals - ZoneId.of("Z"): true
equals - ZoneId.of("+0"): true
isEqual - ZoneId.of("UTC"): true

This is realy old post but here is one my update what I made using correct answer. My solution also use jQuery.

Point of this is to use proper print view, include all stylesheets for the proper formatting and also to be supported in the most browsers.

function PrintElem(elem, title, offset)
{
    // Title constructor
    title = title || $('title').text();
    // Offset for the print
    offset = offset || 0;

    // Loading start
    var dStart = Math.round(new Date().getTime()/1000),
        $html = $('html');
        i = 0;

    // Start building HTML
    var HTML = '<html';

    if(typeof ($html.attr('lang')) !== 'undefined') {
        HTML+=' lang=' + $html.attr('lang');
    }

    if(typeof ($html.attr('id')) !== 'undefined') {
        HTML+=' id=' + $html.attr('id');
    }

    if(typeof ($html.attr('xmlns')) !== 'undefined') {
        HTML+=' xmlns=' + $html.attr('xmlns');
    }

    // Close HTML and start build HEAD
    HTML+='><head>';

    // Get all meta tags
    $('head > meta').each(function(){
        var $this = $(this),
            $meta = '<meta';

        if(typeof ($this.attr('charset')) !== 'undefined') {
            $meta+=' charset=' + $this.attr('charset');
        }

        if(typeof ($this.attr('name')) !== 'undefined') {
            $meta+=' name=' + $this.attr('name');
        }

        if(typeof ($this.attr('http-equiv')) !== 'undefined') {
            $meta+=' http-equiv=' + $this.attr('http-equiv');
        }

        if(typeof ($this.attr('content')) !== 'undefined') {
            $meta+=' content=' + $this.attr('content');
        }

        $meta+=' />';

        HTML+= $meta;
        i++;

    }).promise().done(function(){

        // Insert title
        HTML+= '<title>' + title  + '</title>';

        // Let's pickup all CSS files for the formatting
        $('head > link[rel="stylesheet"]').each(function(){
            HTML+= '<link rel="stylesheet" href="' + $(this).attr('href') + '" />';
            i++;
        }).promise().done(function(){
            // Print setup
            HTML+= '<style>body{display:none;}@media print{body{display:block;}}</style>';

            // Finish HTML
            HTML+= '</head><body>';
            HTML+= '<h1 class="text-center mb-3">' + title  + '</h1>';
            HTML+= elem.html();
            HTML+= '</body></html>';

            // Open new window
            var printWindow = window.open('', 'PRINT', 'height=' + $(window).height() + ',width=' + $(window).width());
            // Append new window HTML
            printWindow.document.write(HTML);

            printWindow.document.close(); // necessary for IE >= 10
            printWindow.focus(); // necessary for IE >= 10*/
console.log(printWindow.document);
            /* Make sure that page is loaded correctly */
            $(printWindow).on('load', function(){                   
                setTimeout(function(){
                    // Open print
                    printWindow.print();

                    // Close on print
                    setTimeout(function(){
                        printWindow.close();
                        return true;
                    }, 3);

                }, (Math.round(new Date().getTime()/1000) - dStart)+i+offset);
            });
        });
    });
}

Later you simple need something like this:

$(document).on('click', '.some-print', function() {
    PrintElem($(this), 'My Print Title');
    return false;
});

Try it.

They sound about the same, however, the exit() also allows you to set the exit code of your PHP script.

Usually you don't really need this, but when writing console PHP scripts, you might want to check with for example Bash if the script completed everything in the right way.

Then you can use exit() and catch that later on. Die() however doesn't support that.

Die() always exists with code 0. So essentially a die() command does the following:

<?php
echo "I am going to die";
exit(0);
?>

Which is the same as:

<?php
die("I am going to die");
?>

Using Windows 10? Go here: https://docs.microsoft.com/en-us/windows/wsl/wsl2-install

Then run...

    $ wget https://github.com/antirez/redis/archive/5.0.5.tar.gz <- change this to whatever Redis version you want (https://github.com/antirez/redis/releases)
    $ tar xzf redis-5.0.5.tar.gz
    $ cd redis-5.0.5
    $ make

Not elegant, but if you don't use your method overlappingly you can also use global variables, defined by the Public statement at the beginning of your code, before the Subs. You have to be cautious though, once you change a public value, it will be held throughout your code in all Subs and Functions.

Protect/Lock Excel VBA Code:

When we write VBA code it is often desired to have the VBA Macro code not visible to end-users. This is to protect your intellectual property and/or stop users messing about with your code. Just be aware that Excel's protection ability is far from what would be considered secure. There are also many VBA Password Recovery [tools] for sale on the www.

To protect your code, open the Excel Workbook and go to Tools>Macro>Visual Basic Editor (Alt+F11). Now, from within the VBE go to Tools>VBAProject Properties and then click the Protection page tab and then check "Lock project from viewing" and then enter your password and again to confirm it. After doing this you must save, close & reopen the Workbook for the protection to take effect.

(Emphasis mine)

Seems like your best bet. It won't stop people determined to steal your code but it's enough to stop casual pirates.

Remember, even if you were able to distribute a compiled copy of your code there'd be nothing to stop people decompiling it.

You can simply access the element classList which received the click event using event.target then by using toggle method on the classList object to add or remove the intended class

<div onClick={({target}) => target.classList.toggle('active')}>
  ....
  ....
  ....
</div>

Equevelent

<div onClick={e=> e.target.classList.toggle('active')}>
  ....
  ....
  ....
</div>

OR by declaring a function that handle the click and does extra work

function handleClick(el){
    .... Do more stuff
    el.classList.toggle('active');

}
<div onClick={({target})=> handleClick(target)}>
  ....
  ....
  ....
</div>

For my case, it was with Toolbar i resolved it like this:

ic_toolbar_drawble.xml

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
    android:drawable="@drawable/ic_toolbar"
    android:right="-16dp"
    android:left="-16dp"/>
</layer-list>

In my Fragment, i check the api :

if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
      toolbar.setLogo(R.drawable.ic_toolbar);
else
      toolbar.setLogo(R.drawable.ic_toolbar_draweble);

Good luck!

I know, this is not really a solution for your question, because you ask for

display + opacity

My approach solves a more general question, but maybe this was the background problem that should be solved by using display in combination with opacity.

My desire was to get the Element out of the way when it is not visible. This solution does exactly that: It moves the element out of the away, and this can be used for transition:

.child {
  left: -2000px;
  opacity: 0;
  visibility: hidden;
  transition: left 0s 0.8s, visibility 0s 0.8s, opacity 0.8s;
}

.parent:hover .child {
  left: 0;
  opacity: 1;
  visibility: visible;
  transition: left 0s, visibility 0s, opacity 0.8s;
}

This code does not contain any browser prefixes or backward compatibility hacks. It just illustrates the concept how the element is moved away as it is not needed any more.

The interesting part are the two different transition definitions. When the mouse-pointer is hovering the .parent element the .child element needs to be put in place immediately and then the opacity will be changed:

transition: left 0s, visibility 0s, opacity 0.8s;

When there is no hover, or the mouse-pointer was moved off the element, one has to wait until the opacity change has finished before the element can be moved off screen:

transition: left 0s 0.8s, visibility 0s 0.8s, opacity 0.8s;

Moving the object away will be a viable alternative in a case where setting display:none would not break the layout.

I hope I hit the nail on the head for this question although I did not answer it.

If it's errors you want to hide you can do it like this

$ErrorActionPreference = "SilentlyContinue"; #This will hide errors
$someObject.SomeFunction();
$ErrorActionPreference = "Continue"; #Turning errors back on

If you want to convert from char to int, why not think about unicode number?

SELECT UNICODE(';') -- 59

This way you can convert any char to int without any error. Cheers.

int given base 2 and then hex:

>>> int('010110', 2)
22
>>> hex(int('010110', 2))
'0x16'
>>> 

>>> hex(int('0000010010001101', 2))
'0x48d'

The doc of int:

int(x[, base]) -> integer

Convert a string or number to an integer, if possible.  A floating

point argument will be truncated towards zero (this does not include a string representation of a floating point number!) When converting a string, use the optional base. It is an error to supply a base when converting a non-string. If base is zero, the proper base is guessed based on the string content. If the argument is outside the integer range a long object will be returned instead.

The doc of hex:

hex(number) -> string

Return the hexadecimal representation of an integer or long

integer.

<form id="csv_file_form" ng-submit="submit_import_csv()" method="POST" enctype="multipart/form-data">
    <input ng-model='file' type="file"/>
    <input type="submit" value='Submit'/>
</form>

In angularJS controller

$scope.submit_import_csv = function(){

        var formData = new FormData(document.getElementById("csv_file_form"));
        console.log(formData);

        $.ajax({
            url: "import",
            type: 'POST',
            data:  formData,
            mimeType:"multipart/form-data",
            contentType: false,
            cache: false,
            processData:false,
            success: function(result, textStatus, jqXHR)
            {
            console.log(result);
            }
        });

        return false;
    }

In create-react-app relative paths for images don't seem to work. Instead, you can import an image:

import logo from './logo.png' // relative path to image 

class Nav extends Component { 
    render() { 
        return ( 
            <img src={logo} alt={"logo"}/> 
        )  
    }
}

Here in this case, we are having 3 parameter's in the Method namely ModelandView.
According to this question, the first parameter is easily understood. It represents the View which will be displayed to the client.
The other two parameters are just like The Pointer and The Holder
Hence you can sum it up like this

ModelAndView(View, Pointer, Holder);

The Pointer just points the information in the The Holder

When the Controller binds the View with this information, then in the said process, you can use The Pointer in the JSP page to access the information stored in The Holder to display that respected information to the client.
Here is the visual depiction of the respected process.

return new ModelAndView("welcomePage", "WelcomeMessage", message);

For example see https://web.archive.org/web/20080506194329/http://www.arthurkoziel.com/2008/05/02/git-configuration/

The interesting part is

Colorized output:

git config --global color.branch auto
git config --global color.diff auto
git config --global color.interactive auto
git config --global color.status auto

return n from your main entry function will terminate your process and report to the parent process (the one that executed your process) the result of your process. 0 means SUCCESS. Other codes usually indicates a failure and its meaning.

Your issue here is that you've supplied a -webkit-TRANSITION-timing-function when you want a -webkit-ANIMATION-timing-function. Your values of 0 to 360 will work properly.

with pure jquery:

window.jQuery.ajax({

    contentType: 'application/json',
    success: function (data) {

        var odd_even = false;
        var response = JSON.parse(data);

        var head = "<thead class='thead-inverse'><tr>";
        $.each(response[0], function (k, v) {
            head = head + "<th scope='row'>" + k.toString() + "</th>";
        })
        head = head + "</thead></tr>";
        $(table).append(head);//append header
       var body="<tbody><tr>";
        $.each(response, function () {

            }) 
            body=body+"</tr>";

This is the same concept as Siddharth Rout's answer. But I wanted a date picker which could be fully customized so that the look and feel could be tailored to whatever project it's being used in.

You can click this link to download the custom date picker I came up with. Below are some screenshots of the form in action.

To use the date picker, simply import the CalendarForm.frm file into your VBA project. Each of the calendars above can be obtained with one single function call. The result just depends on the arguments you use (all of which are optional), so you can customize it as much or as little as you want.

For example, the most basic calendar on the left can be obtained by the following line of code:

MyDateVariable = CalendarForm.GetDate

That's all there is to it. From there, you just include whichever arguments you want to get the calendar you want. The function call below will generate the green calendar on the right:

MyDateVariable = CalendarForm.GetDate( _
    SelectedDate:=Date, _
    DateFontSize:=11, _
    TodayButton:=True, _
    BackgroundColor:=RGB(242, 248, 238), _
    HeaderColor:=RGB(84, 130, 53), _
    HeaderFontColor:=RGB(255, 255, 255), _
    SubHeaderColor:=RGB(226, 239, 218), _
    SubHeaderFontColor:=RGB(55, 86, 35), _
    DateColor:=RGB(242, 248, 238), _
    DateFontColor:=RGB(55, 86, 35), _
    SaturdayFontColor:=RGB(55, 86, 35), _
    SundayFontColor:=RGB(55, 86, 35), _
    TrailingMonthFontColor:=RGB(106, 163, 67), _
    DateHoverColor:=RGB(198, 224, 180), _
    DateSelectedColor:=RGB(169, 208, 142), _
    TodayFontColor:=RGB(255, 0, 0), _
    DateSpecialEffect:=fmSpecialEffectRaised)

Here is a small taste of some of the features it includes. All options are fully documented in the userform module itself:

• Ease of use. The userform is completely self-contained, and can be imported into any VBA project and used without much, if any additional coding.
• Simple, attractive design.
• Fully customizable functionality, size, and color scheme
• Limit user selection to a specific date range
• Choose any day for the first day of the week
• Include week numbers, and support for ISO standard
• Clicking the month or year label in the header reveals selectable comboboxes
• Dates change color when you mouse over them

I realise this is quite an old thread but it's one of the first results when searching for this problem.

There's a simple solution to this which afaik has always been available... This is also the "recommended" way of doing the same task in VBA.

var lastCell = mySheet.getRange(mySheet.getLastRow(),1).getNextDataCell(
  SpreadsheetApp.Direction.UP
);

This will return the last full cell in the column you specify in getRange(row,column), remember to add 1 to this if you want to use the first empty row.

I think style no. 111 (Japan) should work:

SELECT CONVERT(DATETIME, '2012-08-17', 111)

And if that doesn't work for some reason - you could always just strip out the dashes and then you have the totally reliable ISO-8601 format (YYYYMMDD) which works for any language and date format setting in SQL Server:

SELECT CAST(REPLACE('2012-08-17', '-', '') AS DATETIME)

ObservableCollection has several constructors which have input parameter of List<T> or IEnumerable<T>:
List<T> list = new List<T>();
ObservableCollection<T> collection = new ObservableCollection<T>(list);

variable=" Hello..."  
print (variable)  
print("This is the Test File "+variable)  

for integer type ...

variable="  10"  
print (variable)  
print("This is the Test File "+str(variable))  

You can use many ports together for each project,

  php artisan serve --port=8000

  php artisan serve --port=8001   

  php artisan serve --port=8002

  php artisan serve --port=8003

In HTML:

<div (mouseover)="funcName1() (mouseout)="funcName2()">
   // Do what you want 
</div>

In TypeScript:

funcName1(){
 //Do Something
}
funcName2(){
//Do Something
}

You may use the following functions which I wrote in one of my helper class in a project.

just call

showShareActivity(msg:"message", image: nil, url: nil, sourceRect: nil) 

and it will work for both iPhone and iPad. If you pass any view's CGRect value by sourceRect it will also shows a little arrow in iPad.

func topViewController()-> UIViewController{
    var topViewController:UIViewController = UIApplication.shared.keyWindow!.rootViewController!

    while ((topViewController.presentedViewController) != nil) {
        topViewController = topViewController.presentedViewController!;
    }

    return topViewController
}

func showShareActivity(msg:String?, image:UIImage?, url:String?, sourceRect:CGRect?){
    var objectsToShare = [AnyObject]()

    if let url = url {
        objectsToShare = [url as AnyObject]
    }

    if let image = image {
        objectsToShare = [image as AnyObject]
    }

    if let msg = msg {
        objectsToShare = [msg as AnyObject]
    }

    let activityVC = UIActivityViewController(activityItems: objectsToShare, applicationActivities: nil)
    activityVC.modalPresentationStyle = .popover
    activityVC.popoverPresentationController?.sourceView = topViewController().view
    if let sourceRect = sourceRect {
        activityVC.popoverPresentationController?.sourceRect = sourceRect
    }

    topViewController().present(activityVC, animated: true, completion: nil)
}

I guess the following error is caused because of the varying versions of firebase dependencies. For me changing the version of all the dependencies that i'm implementing on my project to 16.0.1, worked like a charm.

For me the error was created by the line: com.google.firebase:firebase-auth:16.0.2

And I changed it to : com.google.firebase:firebase-auth:16.0.1

And it worked.. Hope this helps.

In PHP, passing by reference (&) is ... controversial. I recommend not using it unless you know why you need it and test the results.

I would recommend doing the following:

foreach ($fields as $key => $field) {
    if ($field['required'] && strlen($_POST[$field['name']]) <= 0) {
        $fields[$key]['value'] = "Some error";
    }
}

So basically use $field when you need the values, and $fields[$key] when you need to change the data.

BufferedReader br = new BufferedReader(new InputStreamReader(System.in));   

System.out.println("Enter the sentence : ");

try
{
    String str = br.readLine();
    char[] str1 = new char[str.length()];

    for(int i=0; i<str.length(); i++)
    {
        str1[i] = Character.toLowerCase(str.charAt(i));
    }

    str1[0] = Character.toUpperCase(str1[0]);
    for(int i=0;i<str.length();i++)
    {
        if(str1[i] == ' ')
        {                   
            str1[i+1] =  Character.toUpperCase(str1[i+1]);
        }
        System.out.print(str1[i]);
    }
}
catch(Exception e)
{
    System.err.println("Error: " + e.getMessage());
}

For those who need to figure out simple way

Try getActivity().onBackPressed();

Opening a file creates it and (unless append ('a') is set) overwrites it with emptyness, such as this:

open(filename, 'w').close()

I found very good explanation about .la files here http://openbooks.sourceforge.net/books/wga/dealing-with-libraries.html

Summary (The way I understood): Because libtool deals with static and dynamic libraries internally (through --diable-shared or --disable-static) it creates a wrapper on the library files it builds. They are treated as binary library files with in libtool supported environment.

From a programmatic perspective the Homebrew folks have a check for the existence of various files to determine if the command line tools are installed. Currently it always checks for /Library/Developer/CommandLineTools/usr/bin/git and will also check for /usr/include/iconv.h if the OS version is 10.13 or below.

Add following css to your .validate method to change the css or functionality

 errorElement: "div",
    wrapper: "div",
    errorPlacement: function(error, element) {
        offset = element.offset();
        error.insertAfter(element)
        error.css('color','red');
    }

When Array List contains object of Primitive DataType.

Use this function:
arrayList.contains(value);

if list contains that value then it will return true else false.

When Array List contains object of UserDefined DataType.

I hope this solution will help you. Thanks

"don't tell me about how I should just do it "the right way" or whatever"

OK. _{^{but you should really do it the right way... or whatever}}

" I need a concrete example of how to make it block ... WITHOUT freezing the UI. If such a thing is possible in JS."

No, it is impossible to block the running JavaScript without blocking the UI.

Given the lack of information, it's tough to offer a solution, but one option may be to have the calling function do some polling to check a global variable, then have the callback set data to the global.

function doSomething() {

      // callback sets the received data to a global var
  function callBack(d) {
      window.data = d;
  }
      // start the async
  myAsynchronousCall(param1, callBack);

}

  // start the function
doSomething();

  // make sure the global is clear
window.data = null

  // start polling at an interval until the data is found at the global
var intvl = setInterval(function() {
    if (window.data) { 
        clearInterval(intvl);
        console.log(data);
    }
}, 100);

All of this assumes that you can modify doSomething(). I don't know if that's in the cards.

If it can be modified, then I don't know why you wouldn't just pass a callback to doSomething() to be called from the other callback, but I better stop before I get into trouble. ;)

Oh, what the heck. You gave an example that suggests it can be done correctly, so I'm going to show that solution...

function doSomething( func ) {

  function callBack(d) {
    func( d );
  }

  myAsynchronousCall(param1, callBack);

}

doSomething(function(data) {
    console.log(data);
});

Because your example includes a callback that is passed to the async call, the right way would be to pass a function to doSomething() to be invoked from the callback.

Of course if that's the only thing the callback is doing, you'd just pass func directly...

myAsynchronousCall(param1, func);

datetime.datetime.fromtimestamp() is correct, except you are probably having timestamp in miliseconds (like in JavaScript), but fromtimestamp() expects Unix timestamp, in seconds.

Do it like that:

>>> import datetime
>>> your_timestamp = 1331856000000
>>> date = datetime.datetime.fromtimestamp(your_timestamp / 1e3)

and the result is:

>>> date
datetime.datetime(2012, 3, 16, 1, 0)

Does it answer your question?

EDIT: J.F. Sebastian correctly suggested to use true division by 1e3 (float 1000). The difference is significant, if you would like to get precise results, thus I changed my answer. The difference results from the default behaviour of Python 2.x, which always returns int when dividing (using / operator) int by int (this is called floor division). By replacing the divisor 1000 (being an int) with the 1e3 divisor (being representation of 1000 as float) or with float(1000) (or 1000. etc.), the division becomes true division. Python 2.x returns float when dividing int by float, float by int, float by float etc. And when there is some fractional part in the timestamp passed to fromtimestamp() method, this method's result also contains information about that fractional part (as the number of microseconds).

Here is the simplest python socket example.

Server side:

import socket

serversocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
serversocket.bind(('localhost', 8089))
serversocket.listen(5) # become a server socket, maximum 5 connections

while True:
    connection, address = serversocket.accept()
    buf = connection.recv(64)
    if len(buf) > 0:
        print buf
        break

Client Side:

import socket

clientsocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
clientsocket.connect(('localhost', 8089))
clientsocket.send('hello')

• First run the SocketServer.py, and make sure the server is ready to listen/receive sth
• Then the client send info to the server;
• After the server received sth, it terminates

More based on the feeling, but this is the error you would get if you missed to declare a bean in the context configuration, so try adding

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
    <property name="maxUploadSize" value="10000000"/>
</bean>

I didn't see this solution. I find it simpler for where I currently am in software development:

public static void PrintFigure(int shapeSize)
{
    string figure = "\\/";
    for (int loopTwo = 1; loopTwo <= shapeSize - 1; loopTwo++)
    {
        Console.Write($"{figure}");
    }
}

For security & other reasons, ruby does not by default include the current directory in the load_path. You may want to check this for more details - Why does Ruby 1.9.2 remove "." from LOAD_PATH, and what's the alternative?

Delete the project named Servers (or Servers1, Servers2 which contains your server.xml), find it in Package Explorer(workspace)

Remove server from Eclipse : Go to Window > Preferences > Server > Runtime Environment, here remove the server your are using from eclipse and add it again(doing this will create a new Server project folder in Eclipse) ,

Remove server from Project : Also remove the server in your project(Build path > configuration path > Java Build path) and add again.

now you got a fresh Server project which will not have Multiple Context on its server.xml, only deleting duplicate path in server.xml solved the existing issue but still server dint start, by doing this Server started(Apache Tomcat v7) and worked normal

And I don't know whether this is good practice or not, I am a starter in programming.

You can open any of the following files:

/etc/profile
~/.bash_profile
~/.bash_login   (if .bash_profile does not exist)
~/.profile      (if .bash_login does not exist)

And add:

export PATH="$PATH:your/new/path/here"

You can use a Junit Rule to create this temporary folder for your test:

@Rule public TemporaryFolder temporaryFolder = new TemporaryFolder(); File file = temporaryFolder.newFile(".src/test/resources/abc.xml");

How to run Rmd in command with knitr and rmarkdown by multiple commands and then Upload an HTML file to RPubs

Here is a example: load two libraries and run a R command

R -e 'library("rmarkdown");library("knitr");rmarkdown::render("NormalDevconJuly.Rmd")'

R -e 'library("markdown");rpubsUpload("normalDev","NormalDevconJuly.html")'

You can manually ask Spring to Autowire it.

Have your factory implement ApplicationContextAware. Then provide the following implementation in your factory:

@Override
public void setApplicationContext(final ApplicationContext applicationContext) {
    this.applicationContext = applicationContext;
}

and then do the following after creating your bean:

YourBean bean = new YourBean();
applicationContext.getAutowireCapableBeanFactory().autowireBean(bean);
bean.init(); //If it has an init() method.

This will autowire your LocationService perfectly fine.

There's a Py library that has a module that facilitates access to Json-like dictionary key-values as attributes: https://github.com/asuiu/pyxtension You can use it as:

j = Json('{"lat":444, "lon":555}')
j.lat + ' ' + j.lon

The answers to this question helped me find my problem, but my source was different, so hopefully this can shed light on someone finding this page searching for answers to the 'random' context crash:

I had specified a SharedPreferences object, and tried to instantiate it at it's class-level declaration, like so:

public class MyFragment extends FragmentActivity {
    private SharedPreferences sharedPref =
        PreferenceManager.getDefaultSharedPreferences(this);

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //...

Referencing this before the onCreate caused the "java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String android.content.Context.getPackageName()' on a null object reference" error for me.

Instantiating the object inside the onCreate() solved my problem, like so:

public class MyFragment extends FragmentActivity {
    private SharedPreferences sharedPref;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //...
        sharedPref = PreferenceManager.getDefaultSharedPreferences(this);

Hope that helps.

In Windows, you can use the following registry script to add "Delete SVN Folders" to your right click context menu. Run it on any directory containing those pesky files.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell\DeleteSVN]
@="Delete SVN Folders"

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell\DeleteSVN\command]
@="cmd.exe /c \"TITLE Removing SVN Folders in %1 && COLOR 9A && FOR /r \"%1\" %%f IN (.svn) DO RD /s /q \"%%f\" \""

As i mentioned here

initially set the field type to text.

on focus change it to type date

Strings can be deep copied with

List<String> b = new ArrayList<String>(a);

because they are immutable. Every other Object not --> you need to iterate and do a copy by yourself.

$("selectorbyclassorbyIDorbyName").click(function () {
  $("selectorbyclassorbyIDorbyName").attr("disabled", true).delay(2000).attr("disabled", false);
});

select the button and by its id or text or class ... it just disables after 1st click and enables after 20 Milli sec

Works very well for post backs n place it in Master page, applies to all buttons without calling implicitly like onclientClick

Generally speaking,

$('#startdate').data('date') 

is best because

$('#startdate').val()

not work if you have a datepicker "inline"

/usr/local/lib/node_modules is the correct directory for globally installed node modules.

/usr/local/share/npm/lib/node_modules makes no sense to me. One issue here is that you're confused because there are two directories called node_modules:

/usr/local/lib/node_modules
/usr/local/lib/node_modules/npm/node_modules

The latter seems to be node modules that came with Node, e.g., lodash, when the former is Node modules that I installed using npm.

As of Numpy 1.9, the easiest and fastest method is to simply use numpy.unique, which now has a return_counts keyword argument:

import numpy as np

x = np.array([1,1,1,2,2,2,5,25,1,1])
unique, counts = np.unique(x, return_counts=True)

print np.asarray((unique, counts)).T

Which gives:

 [[ 1  5]
  [ 2  3]
  [ 5  1]
  [25  1]]

A quick comparison with scipy.stats.itemfreq:

In [4]: x = np.random.random_integers(0,100,1e6)

In [5]: %timeit unique, counts = np.unique(x, return_counts=True)
10 loops, best of 3: 31.5 ms per loop

In [6]: %timeit scipy.stats.itemfreq(x)
10 loops, best of 3: 170 ms per loop

I'm writing slider ui control to provide drag feature, this is my way to prevent content from selecting when user is dragging:

function disableSelect(event) {
    event.preventDefault();
}

function startDrag(event) {
    window.addEventListener('mouseup', onDragEnd);
    window.addEventListener('selectstart', disableSelect);
    // ... my other code
}

function onDragEnd() {
    window.removeEventListener('mouseup', onDragEnd);
    window.removeEventListener('selectstart', disableSelect);
    // ... my other code
}

bind startDrag on your dom:

<button onmousedown="startDrag">...</button>

If you want to statically disable text select on all element, execute the code when elements are loaded:

window.addEventListener('selectstart', function(e){ e.preventDefault(); });

      

N=np.floor(np.divide(l,delta))
...
for j in range(N[i]/2):

N[i]/2 will be a float64 but range() expects an integer. Just cast the call to

for j in range(int(N[i]/2)):

Here is an example of a simple service, that uses localStorage to persist data:

import { Injectable } from '@angular/core';

@Injectable()
export class PersistanceService {
  constructor() {}

  set(key: string, data: any): void {
    try {
      localStorage.setItem(key, JSON.stringify(data));
    } catch (e) {
      console.error('Error saving to localStorage', e);
    }
  }

  get(key: string) {
    try {
      return JSON.parse(localStorage.getItem(key));
    } catch (e) {
      console.error('Error getting data from localStorage', e);
      return null;
    }
  }
}

To use this services, provide it in some module in your app like normal, for example in core module. Then use like this:

import { Injectable } from '@angular/core';

@Injectable()
export class SomeOtherService {

  constructor(private persister: PersistanceService) {}

  someMethod() {
    const myData = {foo: 'bar'};
    persister.set('SOME_KEY', myData);
  }

  someOtherMethod() {
    const myData = persister.get('SOME_KEY');
  }
}
