The syntax you wrote as first is not valid. You can achieve something using the follow:

var map =  {"aaa": "rrr", "bbb": "ppp" /* etc */ };

Build.VERSION.RELEASE;

That will give you the actual numbers of your version; aka 2.3.3 or 2.2. The problem with using Build.VERSION.SDK_INT is if you have a rooted phone or custom rom, you could have a none standard OS (aka my android is running 2.3.5) and that will return a null when using Build.VERSION.SDK_INT so Build.VERSION.RELEASE will work no matter what!

To switch to root so that all subsequent commands are executed with high privileges instead of using sudo before each command use following command and then provide the password when prompted.

sudo -i

User will change and remain root until you close the terminal. Execute exit commmand which will change the user back to original user without closing terminal.

Scrollbar CSS styles are an oddity invented by Microsoft developers. They are not part of the W3C standard for CSS and therefore most browsers just ignore them.

If you just want to clobber all of the instances of a substring out of a string without using regex you can using:

    var replacestring = "A B B C D"
    const oldstring = "B";
    const newstring = "E";
    while (replacestring.indexOf(oldstring) > -1) {
        replacestring = replacestring.replace(oldstring, newstring);
    }        
    //result: "A E E C D"

I had to put the statement under the [mysqld] block to make it work. Otherwise the change was not reflected. I have a REL distribution.

Using Context,We can clear app specific files like preference,database file. I have used below code for UI testing using Espresso.

    @Rule
    public ActivityTestRule<HomeActivity> mActivityRule = new ActivityTestRule<>(
            HomeActivity.class);

    public static void clearAppInfo() {
        Activity mActivity = testRule.getActivity();
        SharedPreferences prefs =
                PreferenceManager.getDefaultSharedPreferences(mActivity);
        prefs.edit().clear().commit();
        mActivity.deleteDatabase("app_db_name.db");
    }

This is really a long thread, and probably because the answers albeit correct are not resolving the fundamental question. I came across this site: Version & Build Numbers that provided a clear overview of what is what in the Microsoft Windows world.

Since my interest is to know which exact windows OS I am dealing with, I left aside the entire version rainbow and instead focused on the BuildNumber. The build number may be attained either by:

([Environment]::OSVersion.Version).Build

or by:

(Get-CimInstance Win32_OperatingSystem).buildNumber

the choice is yours which ever way you prefer it. So from there I could do something along the lines of:

    switch ((Get-CimInstance Win32_OperatingSystem).BuildNumber) 
{
    6001 {$OS = "W2K8"}
    7600 {$OS = "W2K8R2"}
    7601 {$OS = "W2K8R2SP1"}    
    9200 {$OS = "W2K12"}
    9600 {$OS = "W2K12R2"}
    14393 {$OS = "W2K16v1607"}
    16229 {$OS = "W2K16v1709"}
    default { $OS = "Not Listed"}

}
Write-Host "Server system: $OS" -foregroundcolor Green

Note: As you can see I used the above just for server systems, however it could easily be applied to workstations or even cleverly extended to support both... but I'll leave that to you.

Enjoy, & have fun!

Use the PHP function

void set_time_limit ( int $seconds )

The maximum execution time, in seconds. If set to zero, no time limit is imposed.

This function has no effect when PHP is running in safe mode. There is no workaround other than turning off safe mode or changing the time limit in the php.ini.

With Hibernate's NativeQuery, you need to return a ResultList instead of a SingleResult, because Hibernate modifies a native query

INSERT INTO bla (a,b) VALUES (2,3) RETURNING id

like

INSERT INTO bla (a,b) VALUES (2,3) RETURNING id LIMIT 1

if you try to get a single result, which causes most databases (at least PostgreSQL) to throw a syntax error. Afterwards, you may fetch the resulting id from the list (which usually contains exactly one item).

This should work:

SELECT * FROM Accounts WHERE Username LIKE '%$query%'

Yes that is correct. "Boolean variables only have two possible values: true (1) and false (0)." cpp tutorial on boolean values

You can do this pretty easily:

@app.route("/")
def home():
    resp = flask.Response("Foo bar baz")
    resp.headers['Access-Control-Allow-Origin'] = '*'
    return resp

Look at flask.Response and flask.make_response()

But something tells me you have another problem, because the after_request should have handled it correctly too.

EDIT
I just noticed you are already using make_response which is one of the ways to do it. Like I said before, after_request should have worked as well. Try hitting the endpoint via curl and see what the headers are:

curl -i http://127.0.0.1:5000/your/endpoint

You should see

> curl -i 'http://127.0.0.1:5000/'
HTTP/1.0 200 OK
Content-Type: text/html; charset=utf-8
Content-Length: 11
Access-Control-Allow-Origin: *
Server: Werkzeug/0.8.3 Python/2.7.5
Date: Tue, 16 Sep 2014 03:47:13 GMT

Noting the Access-Control-Allow-Origin header.

EDIT 2
As I suspected, you are getting a 500 so you are not setting the header like you thought. Try adding app.debug = True before you start the app and try again. You should get some output showing you the root cause of the problem.

For example:

@app.route("/")
def home():
    resp = flask.Response("Foo bar baz")
    user.weapon = boomerang
    resp.headers['Access-Control-Allow-Origin'] = '*'
    return resp

Gives a nicely formatted html error page, with this at the bottom (helpful for curl command)

Traceback (most recent call last):
...
  File "/private/tmp/min.py", line 8, in home
    user.weapon = boomerang
NameError: global name 'boomerang' is not defined

I encounter this issue when I first run LEMP on centos7 refer to this post.

I restart nginx to test the phpinfo page, but get this

http://xxx.xxx.xxx.xxx/info.php is not unreachable now.

Then I use tail -f /var/log/nginx/error.log to see more info. I find is the php-fpm.sock file not exist. Then I reboot the system, everything is OK.

Here may not need to reboot the system as Fath's post, just reload nginx and php-fpm.

restart php-fpm

reload nginx config

You can do it like that 2>&1:

 command > file 2>&1

I tried switching from simplejson to builtin json for GAE 2.7, and had issues with the decimal. If default returned str(o) there were quotes (because _iterencode calls _iterencode on the results of default), and float(o) would remove trailing 0.

If default returns an object of a class that inherits from float (or anything that calls repr without additional formatting) and has a custom __repr__ method, it seems to work like I want it to.

import json
from decimal import Decimal

class fakefloat(float):
    def __init__(self, value):
        self._value = value
    def __repr__(self):
        return str(self._value)

def defaultencode(o):
    if isinstance(o, Decimal):
        # Subclass float with custom repr?
        return fakefloat(o)
    raise TypeError(repr(o) + " is not JSON serializable")

json.dumps([10.20, "10.20", Decimal('10.20')], default=defaultencode)
'[10.2, "10.20", 10.20]'

I ran into similar problem - Invalid value encountered in ... After spending a lot of time trying to figure out what is causing this error I believe in my case it was due to NaN in my dataframe. Check out working with missing data in pandas.

None == None True

np.nan == np.nan False

When NaN is not equal to NaN then arithmetic operations like division and multiplication causes it throw this error.

Couple of things you can do to avoid this problem:

1. Use pd.set_option to set number of decimal to consider in your analysis so an infinitesmall number does not trigger similar problem - ('display.float_format', lambda x: '%.3f' % x).

2. Use df.round() to round the numbers so Panda drops the remaining digits from analysis. And most importantly,

3. Set NaN to zero df=df.fillna(0). Be careful if Filling NaN with zero does not apply to your data sets because this will treat the record as zero so N in the mean, std etc also changes.

I've got two points to add. One, Hudson/Jenkins is all about the plugins. Plugin developers have moved to Jenkins and so should we, the users. Two, I am not personally a big fan of Oracle's products. In fact, I avoid them like the plague. For the money spent on licensing and hardware for an Oracle solution you can hire twice the engineering staff and still have some left over to buy beer every Friday :)

An even simpler solution to the above:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true">
        <color android:color="@color/semitransparent_white" />
    </item>
    <item>
        <color android:color="@color/transparent" />
    </item>
</selector>

Save that in the drawable folder and you're good to go.

For mobiles, it’s better to use it

canvas.width = document.documentElement.clientWidth;
canvas.height = document.documentElement.clientHeight;

because it will display incorrectly after changing the orientation.The “viewport” will be increased when changing the orientation to portrait.See full example

I have not yet found a link to the team's final code. When I do I will post, if another has not done so.

Actually, scala has old Java-style loops with index:

scala> val xs = Array("first","second","third")
xs: Array[java.lang.String] = Array(first, second, third)

scala> for (i <- 0 until xs.length)
     | println("String # " + i + " is "+ xs(i))

String # 0 is first
String # 1 is second
String # 2 is third

Where 0 until xs.length or 0.until(xs.length) is a RichInt method which returns Range suitable for looping.

Also, you can try loop with to:

scala> for (i <- 0 to xs.length-1)
     | println("String # " + i + " is "+ xs(i))
String # 0 is first
String # 1 is second
String # 2 is third

A String is a type of Object. So any method that accepts Object as parameter will surely accept String also. Please provide more of your code if you still do not find a solution.

In the discipline of speech recognition, users are divided into goats and sheeps.

For instance, here on page 89:

Sheeps are people for whom speech recognition works exceptionally well, and goats are people for whom it works exceptionally poorly. Only the voice recognizer knows what separates them. People can't predict whose voice will be recognized easily and whose won't. The best policy is to design the interface so it can handle all kinds of voices in all kinds of environments

Maybe, it is planned to mark Android users as goats in the future to be able to configure the speech recognition engine for goats' needs. ;-)

This is in response to the above post by Efx:

If the URL already contains the var you want to change, then it is added yet again as a hidden field.

Here is a modification of that code as to prevent duplicating vars in the URL:

foreach ($_GET as $key => $value) {
    if ($key != "my_key") {
        echo("<input type='hidden' name='$key' value='$value'/>");
    }
}

Use dt.days to obtain the days attribute as integers.

For eg:

In [14]: s = pd.Series(pd.timedelta_range(start='1 days', end='12 days', freq='3000T'))

In [15]: s
Out[15]: 
0    1 days 00:00:00
1    3 days 02:00:00
2    5 days 04:00:00
3    7 days 06:00:00
4    9 days 08:00:00
5   11 days 10:00:00
dtype: timedelta64[ns]

In [16]: s.dt.days
Out[16]: 
0     1
1     3
2     5
3     7
4     9
5    11
dtype: int64

More generally - You can use the .components property to access a reduced form of timedelta.

In [17]: s.dt.components
Out[17]: 
   days  hours  minutes  seconds  milliseconds  microseconds  nanoseconds
0     1      0        0        0             0             0            0
1     3      2        0        0             0             0            0

Now, to get the hours attribute:

In [23]: s.dt.components.hours
Out[23]:

1     2
2     4
3     6
4     8
5    10
Name: hours, dtype: int64

Not sure why no one is using semicolons. This is how it works for me:

=CONCATENATE(LEFT(A1;1); B1)

Solutions with comma produce an error in Excel.

Here's what I did in my values/themes.xml

    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">

A simple way without any libraries or sets

def mcount(l):
  n = []                  #To store count of each elements
  for x in l:
      count = 0
      for i in range(len(l)):
          if x == l[i]:
              count+=1
      n.append(count)
  a = max(n)              #largest in counts list
  for i in range(len(n)):
      if n[i] == a:
          return(l[i],a)  #element,frequency
  return                  #if something goes wrong

Do a (recursive) Revert operation from a level above the directory you deleted.

As per answer by @ProVi just change to suit the formatting you require

echo %DATE:~10,4%-%DATE:~7,2%-%DATE:~4,2% %TIME:~0,2%:%TIME:~3,2%:%TIME:~6,2%

will return

yyyy-MM-dd hh:mm:ss
2015-09-15 18:36:11

EDIT As per @Jeb comment, whom is correct the above time format will only work if your DATE /T command returns

ddd dd/mm/yyyy
Thu 17/09/2015

It is easy to edit to suit your locale however, by using the indexing of each character in the string returned by the relevant %DATE% environment variable you can extract the parts of the string you need.

eg. Using %DATE~10,4% would expand the DATE environment variable, and then use only the 4 characters that begin at the 11th (offset 10) character of the expanded result

For example if using US styled dates then the following applies

ddd mm/dd/yyyy
Thu 09/17/2015

echo %DATE:~10,4%-%DATE:~4,2%-%DATE:~7,2% %TIME:~0,2%:%TIME:~3,2%:%TIME:~6,2%
2015-09-17 18:36:11

If you have sed:

sed -e '/REFERENCE/d' -e '/ERROR/d' [FILENAME]

Where FILENAME is the name of the text file with the good & bad lines

You could try the search feature in pip,

$ pip search yaml

which looks for packages in PyPI with yaml in the short description. That reveals various packages, including PyYaml, yamltools, and PySyck, among others (Note that PySyck docs recommend using PyYaml, since syck is out of date). Now you know a specific package name, you can install it:

$ pip install pyyaml

If you want to install python yaml system-wide in linux, you can also use a package manager, like aptitude or yum:

$ sudo apt-get install python-yaml
$ sudo yum install python-yaml

Generally speaking, you can update your index mapping using the put mapping api (reference here) :

curl -XPUT 'http://localhost:9200/advert_index/_mapping/advert_type' -d '
{
    "advert_type" : {
        "properties" : {

          //your new mapping properties

        }
    }
}
'

It's especially useful for adding new fields. However, in your case, you will try to change the location type, which will cause a conflict and prevent the new mapping from being used.

You could use the put mapping api to add another property containing the location as a lat/lon array, but you won't be able to update the previous location field itself.

Finally, you will have to reindex your data for your new mapping to be taken into account.

The best solution would really be to create a new index.

If your problem with creating another index is downtime, you should take a look at aliases to make things go smoothly.

You don't need to change the compliance level here, or rather, you should but that's not the issue.

The code compliance ensures your code is compatible with a given Java version.

For instance, if you have a code compliance targeting Java 6, you can't use Java 7's or 8's new syntax features (e.g. the diamond, the lambdas, etc. etc.).

The actual issue here is that you are trying to compile something in a Java version that seems different from the project dependencies in the classpath.

Instead, you should check the JDK/JRE you're using to build.

In Eclipse, open the project properties and check the selected JRE in the Java build path.

If you're using custom Ant (etc.) scripts, you also want to take a look there, in case the above is not sufficient per se.

Here is a solution that looks good under iOS6/7/8/9.

Update 2016-06-10: this still works with iOS 9.3.3

Thanks for all your support, this is now on CocoaPods/Carthage/SPM at https://github.com/fulldecent/FDTextFieldTableViewCell

Basically we take the stock UITableViewCellStyleValue1 and staple a UITextField where the detailTextLabel is supposed to be. This gives us automatic placement for all scenarios: iOS6/7/8/9, iPhone/iPad, Image/No-image, Accessory/No-accessory, Portrait/Landscape, 1x/2x/3x.

Note: this is using storyboard with a UITableViewCellStyleValue1 type cell named "word".

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    cell = [tableView dequeueReusableCellWithIdentifier:@"word"];
    cell.detailTextLabel.hidden = YES;
    [[cell viewWithTag:3] removeFromSuperview];
    textField = [[UITextField alloc] init];
    textField.tag = 3;
    textField.translatesAutoresizingMaskIntoConstraints = NO;
    [cell.contentView addSubview:textField];
    [cell addConstraint:[NSLayoutConstraint constraintWithItem:textField attribute:NSLayoutAttributeLeading relatedBy:NSLayoutRelationEqual toItem:cell.textLabel attribute:NSLayoutAttributeTrailing multiplier:1 constant:8]];
    [cell addConstraint:[NSLayoutConstraint constraintWithItem:textField attribute:NSLayoutAttributeTop relatedBy:NSLayoutRelationEqual toItem:cell.contentView attribute:NSLayoutAttributeTop multiplier:1 constant:8]];
    [cell addConstraint:[NSLayoutConstraint constraintWithItem:textField attribute:NSLayoutAttributeBottom relatedBy:NSLayoutRelationEqual toItem:cell.contentView attribute:NSLayoutAttributeBottom multiplier:1 constant:-8]];
    [cell addConstraint:[NSLayoutConstraint constraintWithItem:textField attribute:NSLayoutAttributeTrailing relatedBy:NSLayoutRelationEqual toItem:cell.detailTextLabel attribute:NSLayoutAttributeTrailing multiplier:1 constant:0]];
    textField.textAlignment = NSTextAlignmentRight;
    textField.delegate = self;
    return cell;
}

Probably your problem is that for Docker that has been installed from default Ubuntu repository, the package name is docker.io

Or package name may be something like docker-ce. Try running

dpkg -l | grep -i docker

to identify what installed package you have

So you need to change package name in commands from https://stackoverflow.com/a/31313851/2340159 to match package name. For example, for docker.io it would be:

sudo apt-get purge -y docker.io
sudo apt-get autoremove -y --purge docker.io
sudo apt-get autoclean

It adds:

The above commands will not remove images, containers, volumes, or user created configuration files on your host. If you wish to delete all images, containers, and volumes run the following command:

sudo rm -rf /var/lib/docker

Remove docker from apparmor.d:

sudo rm /etc/apparmor.d/docker

Remove docker group:

sudo groupdel docker

I'm trying to sort of get my head around what's going on over there. Is there anything IN your "example" folder? Git doesn't track empty folders.

If you branched and switched to your new branch then made a new folder and left it empty, and then did "git commit -a", you wouldn't get that new folder in the commit.

Which means it's untracked, which means checking out a different branch wouldn't remove it.

Put each line in cmd or all of theme in the batch file:

@echo off

if not "%1"=="am_admin" (powershell start -verb runas '%0' am_admin & exit /b)

"Put your command here"

it works fine for me.

Use the mkdtemp() function from the tempfile module:

import tempfile
import shutil

dirpath = tempfile.mkdtemp()
# ... do stuff with dirpath
shutil.rmtree(dirpath)

Solution Using jQuery

 <script src="http://code.jquery.com/jquery-2.1.0.min.js"></script>

 <style>
    #form label{float:left; width:140px;}
    #error_msg{color:red; font-weight:bold;}
 </style>

 <script>
    $(document).ready(function(){
        var $submitBtn = $("#form input[type='submit']");
        var $passwordBox = $("#password");
        var $confirmBox = $("#confirm_password");
        var $errorMsg =  $('<span id="error_msg">Passwords do not match.</span>');

        // This is incase the user hits refresh - some browsers will maintain the disabled state of the button.
        $submitBtn.removeAttr("disabled");

        function checkMatchingPasswords(){
            if($confirmBox.val() != "" && $passwordBox.val != ""){
                if( $confirmBox.val() != $passwordBox.val() ){
                    $submitBtn.attr("disabled", "disabled");
                    $errorMsg.insertAfter($confirmBox);
                }
            }
        }

        function resetPasswordError(){
            $submitBtn.removeAttr("disabled");
            var $errorCont = $("#error_msg");
            if($errorCont.length > 0){
                $errorCont.remove();
            }  
        }


        $("#confirm_password, #password")
             .on("keydown", function(e){
                /* only check when the tab or enter keys are pressed
                 * to prevent the method from being called needlessly  */
                if(e.keyCode == 13 || e.keyCode == 9) {
                    checkMatchingPasswords();
                }
             })
             .on("blur", function(){                    
                // also check when the element looses focus (clicks somewhere else)
                checkMatchingPasswords();
            })
            .on("focus", function(){
                // reset the error message when they go to make a change
                resetPasswordError();
            })

    });
  </script>

And update your form accordingly:

<form id="form" name="form" method="post" action="registration.php"> 
    <label for="username">Username : </label>
    <input name="username" id="username" type="text" /></label><br/>

    <label for="password">Password :</label> 
    <input name="password" id="password" type="password" /><br/>

    <label for="confirm_password">Confirm Password:</label>
    <input type="password" name="confirm_password" id="confirm_password" /><br/>

    <input type="submit" name="submit"  value="registration"  />
</form>

This will do precisely what you asked for:

• validate that the password and confirm fields are equal without clicking the register button
• If password and confirm password field will not match it will place an error message at the side of confirm password field and disable registration button

It is advisable not to use a keyup event listener for every keypress because really you only need to evaluate it when the user is done entering information. If someone types quickly on a slow machine, they may perceive lag as each keystroke will kick off the function.

Also, in your form you are using labels wrong. The label element has a "for" attribute which should correspond with the id of the form element. This is so that when visually impaired people use a screen reader to call out the form field, it will know text belongs to which field.

You need to import not only your secret key, but also the corresponding public key, or you'll get this error.

Try with,

<uses-permission android:name="android.permission.INTERNET"/>

instead of,

<permission  android:name="android.permission.INTERNET"></permission>

You can use:

db.foo.update({}, {$rename:{"name.additional":"name.last"}}, false, true);

Or to just update the docs which contain the property:

db.foo.update({"name.additional": {$exists: true}}, {$rename:{"name.additional":"name.last"}}, false, true);

The false, true in the method above are: { upsert:false, multi:true }. You need the multi:true to update all your records.

Or you can use the former way:

remap = function (x) {
  if (x.additional){
    db.foo.update({_id:x._id}, {$set:{"name.last":x.name.additional}, $unset:{"name.additional":1}});
  }
}

db.foo.find().forEach(remap);

In MongoDB 3.2 you can also use

db.students.updateMany( {}, { $rename: { "oldname": "newname" } } )

The general syntax of this is

db.collection.updateMany(filter, update, options)

https://docs.mongodb.com/manual/reference/method/db.collection.updateMany/

This is how I do it:

br { 
    display: inline;
    content: ' ';
    clear:none;
}

Is it possible to make a search by querySelectorAll using multiple unrelated conditions?

Yes, because querySelectorAll accepts full CSS selectors, and CSS has the concept of selector groups, which lets you specify more than one unrelated selector. For instance:

var list = document.querySelectorAll("form, p, legend");

...will return a list containing any element that is a form or p or legend.

CSS also has the other concept: Restricting based on more criteria. You just combine multiple aspects of a selector. For instance:

var list = document.querySelectorAll("div.foo");

...will return a list of all div elements that also (and) have the class foo, ignoring other div elements.

You can, of course, combine them:

var list = document.querySelectorAll("div.foo, p.bar, div legend");

...which means "Include any div element that also has the foo class, any p element that also has the bar class, and any legend element that's also inside a div."

export is a built-in command of the bash shell and other Bourne shell variants. It is used to mark a shell variable for export to child processes.

You have to allocate the buffer with mallock, and give the read write the pointer to it.

#include <unistd.h>
#include <stdlib.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
int main(){
    ssize_t nrd;
    int fd; 
    int fd1;

    char* buffer = malloc(100*sizeof(char));
    fd = open("bli.txt", O_RDONLY);
    fd1 = open("bla.txt", O_CREAT | O_WRONLY, S_IRUSR | S_IWUSR);
    while (nrd = read(fd,buffer,sizeof(buffer))) {
        write(fd1,buffer,nrd);
    }   

    close(fd);
    close(fd1);
    free(buffer);
    return 0;
}

Make sure that the rad file exists and contains something. It's not perfect but it works.

You can use loop for.

var items = {1, 2, 3}
for(var i = 0; i < items.length; i++) {
  if(i == items.length - 1) {
    res.ok(i);
  }
}

set intersection and dict comprehension can be used here

# the dictionary
d = {1:2, 3:4, 5:6, 7:8}

# the subset of keys I'm interested in
l = (1,5)

>>>{key:d[key] for key in set(l) & set(d)}
{1: 2, 5: 6}

I've found solution with declaring some variables and using spread operator to infer type:

interface XYZ {
  x: number;
  y: number;
  z: number;
}

declare var { z, ...xy }: XYZ;

type XY = typeof xy; // { x: number; y: number; }

It works, but I would be glad to see a better solution.

With the first example, SetPrivateValue won't exist in the build if DEBUG is not defined, with the second example, calls to SetPrivateValue won't exist in the build if DEBUG is not defined.

With the first example, you'll have to wrap any calls to SetPrivateValue with #if DEBUG as well.

With the second example, the calls to SetPrivateValue will be omitted, but be aware that SetPrivateValue itself will still be compiled. This is useful if you're building a library, so an application referencing your library can still use your function (if the condition is met).

If you want to omit the calls and save the space of the callee, you could use a combination of the two techniques:

[System.Diagnostics.Conditional("DEBUG")]
public void SetPrivateValue(int value){
    #if DEBUG
    // method body here
    #endif
}

I think is that the best is to install the virtual environment in a path inside the repository folder, maybe is better inclusive to use a subdirectory dedicated to the environment (I have deleted accidentally my entire project when force installing a virtual environment in the repository root folder, good that I had the project saved in its latest version in Github).

Either the automated installer, or the documentation should indicate the virtualenv path as a relative path, this way you won't run into problems when sharing the project with other people. About the packages, the packages used should be saved by pip freeze -r requirements.txt.

Current thinking seems to be to "tolerate" nulls, that is, to allow them in general, although some operations are less tolerant and may end up throwing NPE. See the discussion of nulls on the Lambda Libraries expert group mailing list, specifically this message. Consensus around option #3 subsequently emerged (with a notable objection from Doug Lea). So yes, the OP's concern about pipelines blowing up with NPE is valid.

It's not for nothing that Tony Hoare referred to nulls as the "Billion Dollar Mistake." Dealing with nulls is a real pain. Even with classic collections (without considering lambdas or streams) nulls are problematic. As fge mentioned in a comment, some collections allow nulls and others do not. With collections that allow nulls, this introduces ambiguities into the API. For example, with Map.get(), a null return indicates either that the key is present and its value is null, or that the key is absent. One has to do extra work to disambiguate these cases.

The usual use for null is to denote the absence of a value. The approach for dealing with this proposed for Java SE 8 is to introduce a new java.util.Optional type, which encapsulates the presence/absence of a value, along with behaviors of supplying a default value, or throwing an exception, or calling a function, etc. if the value is absent. Optional is used only by new APIs, though, everything else in the system still has to put up with the possibility of nulls.

My advice is to avoid actual null references to the greatest extent possible. It's hard to see from the example given how there could be a "null" Otter. But if one were necessary, the OP's suggestions of filtering out null values, or mapping them to a sentinel object (the Null Object Pattern) are fine approaches.

Don't need to use this method:

 .map((res: Response) => res.json() );

Just use this simple method instead of the previous method. hopefully you'll get your result:

.map(res => res );

The new version of this should read like so:

xcrun g++ hw.cpp
./a.out

I believe you need subexpressions. If I remember right you can use the normal () brackets for subexpressions.

This part is From grep manual:

 Back References and Subexpressions
       The back-reference \n, where n is a single digit, matches the substring
       previously matched  by  the  nth  parenthesized  subexpression  of  the
       regular expression.

Do something like ^[^(abc)] should do the trick.

This appears to be what you want, based on the example you gave:

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

It is not recursive (it will not descend into subdirectories). For a nice solution replacing in selected files throughout a tree I would use find:

find . -name '*.html' -print -exec sed -i.bak 's/foo/bar/g' {} \;

The *.html is the expression that files must match, the .bak after the -i makes a copy of the original file, with a .bak extension (it can be any extension you like) and the g at the end of the sed expression tells sed to replace multiple copies on one line (rather than only the first one). The -print to find is a convenience to show which files were being matched. All this depends on the exact versions of these tools on your system.

If subtracting microtimes gives you negative results, try using the function with the argument true (microtime(true)). With true, the function returns a float instead of a string (as it does if it is called without arguments).

hey all...i had a similar problem with my cms system. i needed a hard path for some security aspects. think the best way is like rob wrote. for quick an dirty coding think this works also..:-)

Ask them how they ensure their pages continue to be usable when the user has JavaScript turned off or JavaScript isn't available.

There's no One True Answer, but you're fishing for an answer talking about some strategies for Progressive Enhancement.

Progressive Enhancement consists of the following core principles:

• basic content should be accessible to all browsers
• basic functionality should be accessible to all browsers
• sparse, semantic markup contains all content
• enhanced layout is provided by externally linked CSS
• enhanced behavior is provided by [[Unobtrusive JavaScript|unobtrusive]], externally linked JavaScript
• end user browser preferences are respected

the problem is in the MatInputModule:

exports: [
    MatInputModule
  ]

HTML:

<select id="box1" onChange="myNewFunction(this);">

JavaScript:

function myNewFunction(element) {
    var text = element.options[element.selectedIndex].text;
    // ...
}

If you use the callback URL, then the API can connect to the callback URL and send or receive some data. That means API can connect to you later (after API call).

Example

1. YOU send data using request to API
2. API sends data using second request to YOU

Exact definition should be in API documentation.

i solved the problem i exlained...for example in the file we render the other component,other component name is same with me method of current component such as:

const Login = () => {

}

render(
  <Login/>
)

..for solve this we must change the method name

Use this code:

@for (int i = 0; i < Model.EmploymentType.Count; i++)
{
    @Html.HiddenFor(m => m.EmploymentType[i].Text)
    @Html.CheckBoxFor(m => m.EmploymentType[i].Checked, new { id = "YourId" })
}

You can use this:

DateTime.Now.ToString("yyyy-dd-M--HH-mm-ss");

That's the non-null assertion operator. It is a way to tell the compiler "this expression cannot be null or undefined here, so don't complain about the possibility of it being null or undefined." Sometimes the type checker is unable to make that determination itself.

It is explained here:

A new ! post-fix expression operator may be used to assert that its operand is non-null and non-undefined in contexts where the type checker is unable to conclude that fact. Specifically, the operation x! produces a value of the type of x with null and undefined excluded. Similar to type assertions of the forms <T>x and x as T, the ! non-null assertion operator is simply removed in the emitted JavaScript code.

I find the use of the term "assert" a bit misleading in that explanation. It is "assert" in the sense that the developer is asserting it, not in the sense that a test is going to be performed. The last line indeed indicates that it results in no JavaScript code being emitted.

You can try one of this two methods.

string startupPath = System.IO.Directory.GetCurrentDirectory();

string startupPath = Environment.CurrentDirectory;

Tell me, which one seems to you better

i would do this:

<li *ngFor="let item of data" (click)='onclick(item)'>{{item.picture.url}}</li>

1. Connect to your SQL server instance using management studio
2. Goto Security -> Logins -> (RIGHT CLICK) New Login
3. fill in user details
4. Under User Mapping, select the databases you want the user to be able to access and configure

UPDATE:

You'll also want to goto Security -> Server Roles, and for public check the permissions for TSQL Default TCP/TSQL Default VIA/TSQL Local Machine/TSQL Named Pipesand remove the connect permission

It's not a cut and paste. The CASE expression must return a value, and you are returning a string containing SQL (which is technically a value but of a wrong type). This is what you wanted to write, I think:

SELECT * FROM [Purchasing].[Vendor] WHERE  
CASE
  WHEN @url IS null OR @url = '' OR @url = 'ALL'
    THEN PurchasingWebServiceURL LIKE '%'
  WHEN @url = 'blank'
    THEN PurchasingWebServiceURL = ''
  WHEN @url = 'fail'
    THEN PurchasingWebServiceURL NOT LIKE '%treyresearch%'
  ELSE PurchasingWebServiceURL = '%' + @url + '%' 
END

I also suspect that this might not work in some dialects, but can't test now (Oracle, I'm looking at you), due to not having booleans.

However, since @url is not dependent on the table values, why not make three different queries, and choose which to evaluate based on your parameter?

Here is my approach to handle some edge cases like having whitespaces and other primitive types as values

const str = " c:234 , d:sdfg ,e: true, f:null, g: undefined, h:name "; 

const strToObj = str
  .trim()
  .split(",")
  .reduce((acc, item) => {
    const [key, val = ""] = item.trim().split(":");
    let newVal = val.trim();

    if (newVal == "null") {
      newVal = null;
    } else if (newVal == "undefined") {
      newVal = void 0;
    } else if (!Number.isNaN(Number(newVal))) {
      newVal = Number(newVal);
    }else if (newVal == "true" || newVal == "false") {
      newVal = Boolean(newVal);
    }
    return { ...acc, [key.trim()]: newVal };
  }, {});

this is how I implement it .

let dictionary = self.convertStringToDictionary(responceString)            
     NotificationCenter.default.post(name: NSNotification.Name(rawValue: "SOCKET_UPDATE"), object: dictionary)

In case you use MVC to accomplish it - you will have to do something like this

 <form action="/ControllerName/ActionName" method="post">
        <a href="javascript:;" onclick="parentNode.submit();"><%=n%></a>
        <input type="hidden" name="mess" value=<%=n%>/>
    </form>

I just went through some examples here and did not see the MVC one figured it won't hurt to post it.

Then on your Action in the Controller I would just put <HTTPPost> On the top of it. I believe if you don't have <HTTPGET> on the top of it it would still work but explicitly putting it there feels a bit safer.

use this package and check the docs:

https://laravelcollective.com/docs/5.2/html#drop-down-lists

form you html , you need use this mark

{!! Form::select('size', array('L' => 'Large', 'S' => 'Small'), 'S'); !!}

Another solution is to set the 'onclick' attribute to a function that returns your writeLED function.

document.getElementById('buttonLED'+id).onclick = function(){ return writeLED(1,1)};

This can also be useful for other cases when you create an element in JavaScript while it has not yet been drawn in the browser.

Add this to your web config and change the catalog name which is your database name:

  <connectionStrings>
    <add name="MyConnectionString" connectionString="Data Source=SERGIO-DESKTOP\SQLEXPRESS;Initial Catalog=YourDatabaseName;Integrated Security=True;"/></connectionStrings>

Reference System.Configuration assembly in your project.

Here is how you retrieve connection string from the config file:

System.Configuration.ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString;

Edit (as suggested in comments and other people), Visual Studio Code has evolved and provides this functionality in-built as the command "Organize imports", with the following default keyboard shortcuts:

option+Shift+O for Mac

Alt + Shift + O for Windows

Original answer:

I hope this visual studio code extension will suffice your need: https://marketplace.visualstudio.com/items?itemName=rbbit.typescript-hero

It provides following features:

• Add imports of your project or libraries to your current file
• Add an import for the current name under the cursor
• Add all missing imports of a file with one command
• Intellisense that suggests symbols and automatically adds the needed imports "Light bulb feature" that fixes code you wrote
• Sort and organize your imports (sort and remove unused)
• Code outline view of your open TS / TSX document
• All the cool stuff for JavaScript as well! (experimental stage though, better description below.)

For Mac: control+option+o

For Win: Ctrl+Alt+o

Python 2

What you're looking for is urllib.quote_plus:

>>> urllib.quote_plus('string_of_characters_like_these:$#@=?%^Q^$')
'string_of_characters_like_these%3A%24%23%40%3D%3F%25%5EQ%5E%24'

Python 3

In Python 3, the urllib package has been broken into smaller components. You'll use urllib.parse.quote_plus (note the parse child module)

import urllib.parse
urllib.parse.quote_plus(...)

I found it very annoying that ggplot2 doesn't offer an 'automatic' solution for this. That's why I created the bar_chart() function in ggcharts.

ggcharts::bar_chart(theTable, Position)

By default bar_chart() sorts the bars and displays a horizontal plot. To change that set horizontal = FALSE. In addition, bar_chart() removes the unsightly 'gap' between the bars and the axis.

If you still have problem then please try this.

Build Settings -> User Defined -> Provisioning profile (Remove this.)

It will solved my issue.

Thanks

@jim's answer is correct -- fuser is what you want.

Additionally (or alternately), you can use lsof to get more information including the username, in case you need permission (without having to run an additional command) to kill the process. (THough of course, if killing the process is what you want, fuser can do that with its -k option. You can have fuser use other signals with the -s option -- check the man page for details.)

For example, with a tail -F /etc/passwd running in one window:

ghoti@pc:~$ lsof | grep passwd
tail      12470    ghoti    3r      REG  251,0     2037 51515911 /etc/passwd

Note that you can also use lsof to find out what processes are using particular sockets. An excellent tool to have in your arsenal.

A char is an integral type. When you write

char ch = 'A';

you're setting the value of ch to whatever number your compiler uses to represent the character 'A'. That's usually the ASCII code for 'A' these days, but that's not required. You're almost certainly using a system that uses ASCII.

Like any numeric type, you can initialize it with an ordinary number:

char ch = 13;

If you want do do arithmetic on a char value, just do it: ch = ch + 1; etc.

However, in order to display the value you have to get around the assumption in the iostreams library that you want to display char values as characters rather than numbers. There are a couple of ways to do that.

std::cout << +ch << '\n';
std::cout << int(ch) << '\n'

Just use:

your_type x;
while (std::cin >> x)
{
    // use x
}

operator>> will skip whitespace by default. You can chain things to read several variables at once:

if (std::cin >> my_string >> my_number)
    // use them both

getline() reads everything on a single line, returning that whether it's empty or contains dozens of space-separated elements. If you provide the optional alternative delimiter ala getline(std::cin, my_string, ' ') it still won't do what you seem to want, e.g. tabs will be read into my_string.

Probably not needed for this, but a fairly common requirement that you may be interested in sometime soon is to read a single newline-delimited line, then split it into components...

std::string line;
while (std::getline(std::cin, line))
{
    std::istringstream iss(line);
    first_type first_on_line;
    second_type second_on_line;
    third_type third_on_line;
    if (iss >> first_on_line >> second_on_line >> third_on_line)
        ...
}

Use MultiDataTrigger type

<Style TargetType="ListBoxItem">
    <Style.Triggers>
      <DataTrigger Binding="{Binding Path=State}" Value="WA">
        <Setter Property="Foreground" Value="Red" />
      </DataTrigger>    
      <MultiDataTrigger>
        <MultiDataTrigger.Conditions>
          <Condition Binding="{Binding Path=Name}" Value="Portland" />
          <Condition Binding="{Binding Path=State}" Value="OR" />
        </MultiDataTrigger.Conditions>
        <Setter Property="Background" Value="Cyan" />
      </MultiDataTrigger>
    </Style.Triggers>
  </Style>

You can simply typecast, and it will do the conversion for you, e.g.

var with = (double?) jToken[key] ?? 100;

It will automatically return null if said key is not present in the object, so there's no need to test for it.

You can do this by setting a style in your paragraph tag. For example if you wanted to change the font size to 28px.

<p style="font-size: 28px;"> Hello, World! </p>

You can also set the color by setting:

<p style="color: blue;"> Hello, World! </p>

However, if you want to preview font sizes and colors (which I recommend doing) before you add them to your website and use them. I recommend testing them out beforehand so you pick a good font size and color that contrasts well with the background. I recommend using this site if you wish to do so, couldn't find anything else: http://fontpreview.herokuapp.com/

CAST(Round(MySum * 20.0 /100, 0) AS INT)

FYI

MySum * 20 /100, I get 11

This is because when all 3 operands are INTs, SQL Server will do perform integer maths, from left to right, truncating all intermediate results.

58 * 20 / 100 => 1160 / 100 => 11 (truncated from 11.6)

Also for the record ROUND(m,n) returns the result to n decimal places, not n significant figures.

var sqlCommand = new SqlCommand("SELECT * FROM mytable WHERE start_time >= @StartTime");
sqlCommand.Parameters.Add("@StartTime", SqlDbType.DateTime);
sqlCommand.Parameters("@StartTime").Value = MyDateObj;

It's a table-valued function, but you're using it as a scalar function.

Try:

where Emp_Id IN (SELECT i.items FROM dbo.Splitfn(@Id,',') AS i)

But... also consider changing your function into an inline TVF, as it'll perform better.

You can simply add these lines of codes here to hide a row,

Either you can write border:0 or border-style:hidden; border: none or it will happen the same thing

running these lines of codes can solve the problem easily

Simple: you can't.

Here is a simple example of adding an image to a JFrame:

frame.add(new JLabel(new ImageIcon("Path/To/Your/Image.png")));

As was in my case if your sql is generated by concatenating or uses converts then sql at execute need to be prefixed with letter N as below

e.g.

Exec N'Select bla..' 

the N defines string literal is unicode.

If BranchA has not been pushed to a remote then you can reorder the commits using rebase and then simply merge. It's preferable to use merge over rebase when possible because it doesn't create duplicate commits.

git checkout BranchA
git rebase -i HEAD~113
... reorder the commits so the 10 you want are first ...
git checkout BranchB
git merge [the 10th commit]

The literal answer is:

return (value == 1 ? Periods.VariablePeriods : Periods.FixedPeriods);

Note that the inline if statement, just like an if statement, only checks for true or false. If (value == 1) evaluates to false, it might not necessarily mean that value == 2. Therefore it would be safer like this:

return (value == 1
    ? Periods.VariablePeriods
    : (value == 2
        ? Periods.FixedPeriods
        : Periods.Unknown));

If you add more values an inline if will become unreadable and a switch would be preferred:

switch (value)
{
case 1:
    return Periods.VariablePeriods;
case 2:
    return Periods.FixedPeriods;
}

The good thing about enums is that they have a value, so you can use the values for the mapping, as user854301 suggested. This way you can prevent unnecessary branches thus making the code more readable and extensible.

If you want to know what properties (and methods) there are:

Get-WmiObject -Class "Win32_computersystem" | Get-Member

The SQL Query select * from openjson ... works only with SQL version 2016 and higher. Need the SQL compatibility mode 130.

Use the "not" selector.

For example, instead of:

$(".thumbs").hover()

try:

$(".thumbs:not(.selected)").hover()

If I understand correctly, you want flex-2-child to fill the height and width of its parent, so that the red area is fully covered by the green?

If so, you just need to set flex-2 to use Flexbox:

.flex-2 {
    display: flex;
}

Then tell flex-2-child to become flexible:

.flex-2-child {
    flex: 1;
}

The reason is that flex-2-child is not a Flexbox item, but its parent is.

a[len(a):] - This gets you the length of a to the end. It selects a range. If you reverse a[:len(a)] it will get you the beginning to whatever is len(a).

The most efficient selector you can use is an attribute selector.

Here's a live demo: http://tinkerbin.com/3G6B93Cb

You can update your provisioning certificates in XCode at:

Organizer -> Devices -> LIBRARY -> Provisioning Profiles

There is a refresh button :) So if you have created the certificate manually in iTunes connect, then you need to press this button or download the certificate manually.

You can parse with module re using named groups. It won't parse the substrings to their actual datatypes (e.g. int) but it's very convenient when parsing strings.

Given this sample line from /proc/net/tcp:

line="   0: 00000000:0203 00000000:0000 0A 00000000:00000000 00:00000000 00000000     0        0 335 1 c1674320 300 0 0 0"

An example mimicking your sscanf example with the variable could be:

import re
hex_digit_pattern = r"[\dA-Fa-f]"
pat = r"\d+: " + \
      r"(?P<local_addr>HEX+):(?P<local_port>HEX+) " + \
      r"(?P<rem_addr>HEX+):(?P<rem_port>HEX+) " + \
      r"HEX+ HEX+:HEX+ HEX+:HEX+ HEX+ +\d+ +\d+ " + \
      r"(?P<inode>\d+)"
pat = pat.replace("HEX", hex_digit_pattern)

values = re.search(pat, line).groupdict()

import pprint; pprint values
# prints:
# {'inode': '335',
#  'local_addr': '00000000',
#  'local_port': '0203',
#  'rem_addr': '00000000',
#  'rem_port': '0000'}

I suggest you try JMapper Framework.

It is a Java bean to Java bean mapper, allows you to perform the passage of data dynamically with annotations and / or XML.

With JMapper you can:

• Create and enrich target objects
• Apply a specific logic to the mapping
• Automatically manage the XML file
• Implement the 1 to N and N to 1 relationships
• Implement explicit conversions
• Apply inherited configurations

While other answers were usable, this really helped me, so I am putting it also here.

From the documentation:

Instead of specifying a context, you can pass a single Dockerfile in the URL or pipe the file in via STDIN. To pipe a Dockerfile from STDIN:

$ docker build - < Dockerfile

With Powershell on Windows, you can run:

Get-Content Dockerfile | docker build -

When the build is done, run command:

docker image ls

You will see something like this:

REPOSITORY                 TAG                 IMAGE ID            CREATED             SIZE
<none>                     <none>              123456789        39 seconds ago      422MB

Copy your actual IMAGE ID and then run

docker run 123456789

Where the number at the end is the actual Image ID from previous step

If you do not want to remember the image id, you can tag your image by

docker tag 123456789 pavel/pavel-build

Which will tag your image as pavel/pavel-build

the react docs explain this nicely in the documentation, you have to use process.env.PUBLIC_URL with images placed in the public folder. See here for more info

return <img src={process.env.PUBLIC_URL + '/img/logo.png'} />;

What's wrong with

%s/style="[^"]*"//g

Use PowerShell:

$Server = "TestServer"
$Database = "TestDatabase"
$Query = "select * from TestTable"
$FilePath = "C:\OutputFile.csv"

# This will overwrite the file if it already exists.
Invoke-Sqlcmd -Query $Query -Database $Database -ServerInstance $Server | Export-Csv $FilePath

In my usual cases, all I really need is a CSV file that can be read by Excel. However, if you need an actual Excel file, then tack on some code to convert the CSV file to an Excel file. This answer gives a solution for this, but I've not tested it.

It seems that your configuration is using the print option for numpy.seterr:

>>> import numpy as np
>>> np.array([1])/0   #'warn' mode
__main__:1: RuntimeWarning: divide by zero encountered in divide
array([0])
>>> np.seterr(all='print')
{'over': 'warn', 'divide': 'warn', 'invalid': 'warn', 'under': 'ignore'}
>>> np.array([1])/0   #'print' mode
Warning: divide by zero encountered in divide
array([0])

This means that the warning you see is not a real warning, but it's just some characters printed to stdout(see the documentation for seterr). If you want to catch it you can:

1. Use numpy.seterr(all='raise') which will directly raise the exception. This however changes the behaviour of all the operations, so it's a pretty big change in behaviour.
2. Use numpy.seterr(all='warn'), which will transform the printed warning in a real warning and you'll be able to use the above solution to localize this change in behaviour.

Once you actually have a warning, you can use the warnings module to control how the warnings should be treated:

>>> import warnings
>>> 
>>> warnings.filterwarnings('error')
>>> 
>>> try:
...     warnings.warn(Warning())
... except Warning:
...     print 'Warning was raised as an exception!'
... 
Warning was raised as an exception!

Read carefully the documentation for filterwarnings since it allows you to filter only the warning you want and has other options. I'd also consider looking at catch_warnings which is a context manager which automatically resets the original filterwarnings function:

>>> import warnings
>>> with warnings.catch_warnings():
...     warnings.filterwarnings('error')
...     try:
...         warnings.warn(Warning())
...     except Warning: print 'Raised!'
... 
Raised!
>>> try:
...     warnings.warn(Warning())
... except Warning: print 'Not raised!'
... 
__main__:2: Warning: 

Another solution in case it helps: in my case, the problem was that I had a @RequestMapping("/xxx") at class level (in my controller), and in the exposed services I had @PostMapping (value = "/yyyy") and @GetMapping (value = "/zzz"); once I commented the @RequestMapping("/xxx") and managed all at method level, worked like a charm.

import urllib2

try:
    fileHandle = urllib2.urlopen('http://www.python.org/fish.html')
    data = fileHandle.read()
    fileHandle.close()
except urllib2.URLError, e:
    print 'you got an error with the code', e

I had the same problem. I solved with move the references and in less than 15 minutes, without change the references.

For me the solution was simple:

1. Move your files where you need.
2. Delete the folder with name .vs. Must be as not visible folder.
3. Open the solution file (.sln) using a simple editor like note or notepad++.
4. Change the reference where your file is, using the following structure: if you put your project in the same folder remove the previous folder or the reference "..\"; if you put in a above folder add the reference "..\" or the name of the folder.
5. Save the file with the changes.
6. Open the project file (.csproj) and do the same, remove or add the reference.
7. Save the changes.
8. Open the solution file.

Examples:

In solution file (.sln)

This error mostly comes when we forcefully kill the weblogic server ("kill -9 process id"), so before restart kindly check all the ports status which weblogic using e.g. http port , DEBUG_PORT etc by using this command to see which whether this port is active or not.

netstat –an | grep (Admin: 7001 or something, Managed server- 7002, 7003 etc) eg: netstat –an | grep 7001

If it returns value then, option 1: wait for some time, so that background process can release the port option 2: execute stopweblogic.sh Option 3: Bounce the server/host or restart the system.

My issue was resolved by option 2.

you can also skip creating dictionary altogether. i used below approach to same problem .

 mappedItems: {};
 items.forEach(item => {     
        if (mappedItems[item.key]) {
           mappedItems[item.key].push({productId : item.productId , price : item.price , discount : item.discount});
        } else {
          mappedItems[item.key] = [];
          mappedItems[item.key].push({productId : item.productId , price : item.price , discount : item.discount}));
        }
    });

Just add quotes around the size in your code. Using this you can use percentage in width, height

input: {
    width: '80%'
}

Somthing like this should workL

SELECT BookingId, StartTime
FROM Booking
WHERE StartTime between dateadd(hour, -1, getdate()) and getdate()

Delete your provisioning profiles, do a 'Clean All', make sure that your provisioning setting are correct, redownload, and try to run again.

UPDATE: starting from Pandas 0.20.1 the .ix indexer is deprecated, in favor of the more strict .iloc and .loc indexers.

I had the same problem, just use console.log(...) (like firebug), and the install a log viewer application, this will allow you to view all the logs for your browser.

insert into sample2 values (1,'2012-01-01','testing');

And here is how to select the data

SELECT Created_Date
FROM sample2
WHERE Created_Date >= DATEADD(day,-11117, GETDATE())

It sounds like the method really should be static (i.e. it doesn't access any data members and it doesn't need an instance to be invoked on). Since you used the term "static class", I understand that the whole class is probably dedicated to utility-like methods that could be static.

However, Java doesn't allow the implementation of an interface-defined method to be static. So when you (naturally) try to make the method static, you get the "cannot-hide-the-instance-method" error. (The Java Language Specification mentions this in section 9.4: "Note that a method declared in an interface must not be declared static, or a compile-time error occurs, because static methods cannot be abstract.")

So as long as the method is present in xInterface, and your class implements xInterface, you won't be able to make the method static.

If you can't change the interface (or don't want to), there are several things you can do:

• Make the class a singleton: make the constructor private, and have a static data member in the class to hold the only existing instance. This way you'll be invoking the method on an instance, but at least you won't be creating new instances each time you need to call the method.
• Implement 2 methods in your class: an instance method (as defined in xInterface), and a static method. The instance method will consist of a single line that delegates to the static method.

The problem is that if you include fun.cpp in two places in your program, you will end up defining it twice, which isn't valid.

You don't want to include cpp files. You want to include header files.

The header file should just have the class definition. The corresponding cpp file, which you will compile separately, will have the function definition.

fun.hpp:

#include <iostream>

class classA {
    friend void funct();
public:
    classA(int a=1,int b=2):propa(a),propb(b){std::cout<<"constructor\n";}
private:
    int propa;
    int propb;
    void outfun(){
        std::cout<<"propa="<<propa<<endl<<"propb="<<propb<< std::endl;
    }
};

fun.cpp:

#include "fun.hpp"

using namespace std;

void funct(){
    cout<<"enter funct"<<endl;
    classA tmp(1,2);
    tmp.outfun();
    cout<<"exit funct"<<endl;
}

mainfile.cpp:

#include <iostream>
#include "fun.hpp"
using namespace std;

int main(int nargin,char* varargin[]) {
    cout<<"call funct"<<endl;
    funct();
    cout<<"exit main"<<endl;
    return 0;
}

Note that it is generally recommended to avoid using namespace std in header files.

Another way to do it would be to inspect the url bar in chrome to find the id of the element, have your WebDriver click that element, and then send the keys you use to copy and paste using the keys common function from selenium, and then printing it out or storing it as a variable, etc.

1. Save and close all Internet Explorer windows and then, run Windows Task Manager to end the running processes in background.
2. Go to Control Panel.
3. Click Programs and choose the View installed updates instead.
4. Locate the following Windows Internet Explorer 11 or you can type "Internet Explorer" for a quick search.
5. Choose the Yes option from the following "Uninstall an update".
6. Please wait while Windows Internet Explorer 10 is being restored and reconfigured automatically.
7. Follow the Microsoft Windows wizard to restart your system.

Note: You can do it for as many earlier versions you want, i.e. IE9, IE8 and so on.

Maybe you want set -e:

www.davidpashley.com/articles/writing-robust-shell-scripts.html#id2382181:

This tells bash that it should exit the script if any statement returns a non-true return value. The benefit of using -e is that it prevents errors snowballing into serious issues when they could have been caught earlier. Again, for readability you may want to use set -o errexit.

Can also invoke oShell.Exec in order to be able to read STDIN/STDOUT/STDERR responses. Perfect for error checking which it seems you're doing with your sanity .BAT.

All algorithms can be defined recursively. That makes it much, much easier to visualize and prove.

Some algorithms (e.g., the Ackermann Function) cannot (easily) be specified iteratively.

A recursive implementation will use more memory than a loop if tail call optimization can't be performed. While iteration may use less memory than a recursive function that can't be optimized, it has some limitations in its expressive power.

I suggest to use a tick symbol not draw it. Or use webfonts which are free for example: fontello[dot]com You can than replace the tick symbol with a web font glyph.

Lists

ul {padding: 0;}
li {list-style: none}
li:before {
  display:inline-block;
  vertical-align: top;
  line-height: 1em;
  width: 1em;
  height:1em;
  margin-right: 0.3em;
  text-align: center;
  content: '?';
  color: #999;
}

See here: http://jsfiddle.net/hpmW7/3/

Checkboxes

You even have web fonts with tick symbol glyphs and CSS 3 animations. For IE8 you would need to apply a polyfill since it does not understand :checked.

input[type="checkbox"] {
  clip: rect(1px, 1px, 1px, 1px);
  left: -9999px;
  position: absolute !important;
}
label:before,
input[type="checkbox"]:checked + label:before {
  content:'';
  display:inline-block;
  vertical-align: top;
  line-height: 1em;
  border: 1px solid #999;
  border-radius: 0.3em;
  width: 1em;
  height:1em;
  margin-right: 0.3em;
  text-align: center;
}
input[type="checkbox"]:checked + label:before {
  content: '?';
  color: green;
}

See the JS fiddle: http://jsfiddle.net/VzvFE/37

If you are using bootstrap.min.css for carousel-

<a class="left carousel-control" href="#carouselExample" data-slide="prev">
  <span class="glyphicon glyphicon-chevron-left"></span>

</a>
<a class="right carousel-control" href="#carouselExample" data-slide="next">
  <span class="glyphicon glyphicon-chevron-right"></span>
  <span class="sr-only">Next</span>
</a>

Open the bootstrap.min.css file and find the property "glyphicon-chevron-right" and add the property "color:red"

The select box arrow is a native ui element, it depends on the desktop theme or the web browser. Use a jQuery plugin (e.g. Select2, Chosen) or CSS.

TextInputLayout til = (TextInputLayout)editText.getParent();
til.setErrorEnabled(true);
til.setError("some error..");

You can use show innodb status (or show engine innodb status for newer versions of mysql) to get a list of all the actions currently pending inside the InnoDB engine. Buried in the wall of output will be the transactions, and what internal process ID they're running under.

You won't be able to force a commit or rollback of those transactions, but you CAN kill the MySQL process running them, which does essentially boil down to a rollback. It kills the processes' connection and causes MySQL to clean up the mess its left.

Here's what you'd want to look for:

------------
TRANSACTIONS
------------
Trx id counter 0 140151
Purge done for trx's n:o < 0 134992 undo n:o < 0 0
History list length 10
LIST OF TRANSACTIONS FOR EACH SESSION:
---TRANSACTION 0 0, not started, process no 17004, OS thread id 140621902116624
MySQL thread id 10594, query id 10269885 localhost marc
show innodb status

In this case, there's just one connection to the InnoDB engine right now (my login, running the show query). If that line were an actual connection/stuck transaction you'd want to terminate, you'd then do a kill 10594.

This is an inevitably long yet easy to follow explanation from ProGit book:

Note: For reference you can read Chapter 7.7 of the book, Reset Demystified

Git as a system manages and manipulates three trees in its normal operation:

• HEAD: Last commit snapshot, next parent
• Index: Proposed next commit snapshot
• Working Directory: Sandbox

The HEAD

HEAD is the pointer to the current branch reference, which is in turn a pointer to the last commit made on that branch. That means HEAD will be the parent of the next commit that is created. It’s generally simplest to think of HEAD as the snapshot of your last commit on that branch.

What does it contain?
To see what that snapshot looks like run the following in root directory of your repository:

                                 git ls-tree -r HEAD

it would result in something like this:

                       $ git ls-tree -r HEAD  
                       100644 blob a906cb2a4a904a152... README  
                       100644 blob 8f94139338f9404f2... Rakefile  
                       040000 tree 99f1a6d12cb4b6f19... lib  

The Index

Git populates this index with a list of all the file contents that were last checked out into your working directory and what they looked like when they were originally checked out. You then replace some of those files with new versions of them, and git commit converts that into the tree for a new commit.

What does it contain?
Use git ls-files -s to see what it looks like. You should see something like this:

                 100644 a906cb2a4a904a152e80877d4088654daad0c859 0 README   
                 100644 8f94139338f9404f26296befa88755fc2598c289 0 Rakefile  
                 100644 47c6340d6459e05787f644c2447d2595f5d3a54b 0 lib/simplegit.rb  

The Working Directory

This is where your files reside and where you can try changes out before committing them to your staging area (index) and then into history.

Visualized Sample

Let's see how do these three trees (As the ProGit book refers to them) work together?
Git’s typical workflow is to record snapshots of your project in successively better states, by manipulating these three trees. Take a look at this picture:

To get a good visualized understanding consider this scenario. Say you go into a new directory with a single file in it. Call this v1 of the file. It is indicated in blue. Running git init will create a Git repository with a HEAD reference which points to the unborn master branch

At this point, only the working directory tree has any content. Now we want to commit this file, so we use git add to take content in the working directory and copy it to the index.

Then we run git commit, which takes the contents of the index and saves it as a permanent snapshot, creates a commit object which points to that snapshot, and updates master to point to that commit.

If we run git status, we’ll see no changes, because all three trees are the same.

The beautiful point

git status shows the difference between these trees in the following manner:

• If the Working Tree is different from index, then git status will show there are some changes not staged for commit
• If the Working Tree is the same as index, but they are different from HEAD, then git status will show some files under changes to be committed section in its result
• If the Working Tree is different from the index, and index is different from HEAD, then git status will show some files under changes not staged for commit section and some other files under changes to be committed section in its result.

For the more curious

Note about git reset command
Hopefully, knowing how reset command works will further brighten the reason behind the existence of these three trees.

reset command is your Time Machine in git which can easily take you back in time and bring some old snapshots for you to work on. In this manner, HEAD is the wormhole through which you can travel in time. Let's see how it works with an example from the book:

Consider the following repository which has a single file and 3 commits which are shown in different colours and different version numbers:

The state of trees is like the next picture:

Step 1: Moving HEAD (--soft):

The first thing reset will do is move what HEAD points to. This isn’t the same as changing HEAD itself (which is what checkout does). reset moves the branch that HEAD is pointing to. This means if HEAD is set to the master branch, running git reset 9e5e6a4 will start by making master point to 9e5e6a4. If you call reset with --soft option it will stop here, without changing index and working directory. Our repo will look like this now:
Notice: HEAD~ is the parent of HEAD

Looking a second time at the image, we can see that the command essentially undid the last commit. As the working tree and the index are the same but different from HEAD, git status will now show changes in green ready to be committed.

Step 2: Updating the index (--mixed):

This is the default option of the command

Running reset with --mixed option updates the index with the contents of whatever snapshot HEAD points to currently, leaving Working Directory intact. Doing so, your repository will look like when you had done some work that is not staged and git status will show that as changes not staged for commit in red. This option will also undo the last commit and also unstage all the changes. It's like you made changes but have not called git add command yet. Our repo would look like this now:

Step 3: Updating the Working Directory (--hard)

If you call reset with --hard option it will copy contents of the snapshot HEAD is pointing to into HEAD, index and Working Directory. After executing reset --hard command, it would mean like you got back to a previous point in time and haven't done anything after that at all. see the picture below:

Conclusion

I hope now you have a better understanding of these trees and have a great idea of the power they bring to you by enabling you to change your files in your repository to undo or redo things you have done mistakenly.

you should use bootstrap v.4

<div class="form-group row">
    <div class="col-md-6">
        <input type="button" class="btn form-control" id="btn1">
    </div>
    <div class="col-md-6">
        <input type="button" class="btn form-control" id="btn2">
    </div>
</div>

Some things to try:

• is the secure_file_priv system variable set? If it is, all files must be written to that directory.
• ensure that the file does not exist - MySQL will only create new files, not overwrite existing ones.

1. With Swift 4, you can use the code below to get your app's home directory. Your app's document directory is in there.

   print(NSHomeDirectory())

2. I think you already know that your app's home directory is changeable, so if you don't want to add additional code to your codebase, SimPholder is a nice tool for you.

3. And further more, you may wonder is there a tool, that can help you save time from closing and reopening same SQLite database every time after your app's home directory be changed. And the answer is yes, a tool I know is SQLiteFlow. From it's document, it says that:

   Handle database file name or directory changes. This makes SQLiteFlow can work friendly with your SQLite database in iOS simulator.

Set<String> stringSet= new HashSet<>();
String[] s = (String[])stringSet.toArray();

It's because you haven't declared outchar before you use it. That means that the compiler will assume it's a function returning an int and taking an undefined number of undefined arguments.

You need to add a prototype pf the function before you use it:

void outchar(char);  /* Prototype (declaration) of a function to be called */  int main(void) {     ... }  void outchar(char ch) {     ... } 

Note the declaration of the main function differs from your code as well. It's actually a part of the official C specification, it must return an int and must take either a void argument or an int and a char** argument.

I have faced the same problem and I solved as give db_owner permission too to the Database user.

From @Ben Bolker:

[T]his has nothing specifically to do with dplyr::filter()

From @Marat Talipov:

[A]ny comparison with NA, including NA==NA, will return NA

From a related answer by @farnsy:

The == operator does not treat NA's as you would expect it to.

Think of NA as meaning "I don't know what's there". The correct answer to 3 > NA is obviously NA because we don't know if the missing value is larger than 3 or not. Well, it's the same for NA == NA. They are both missing values but the true values could be quite different, so the correct answer is "I don't know."

R doesn't know what you are doing in your analysis, so instead of potentially introducing bugs that would later end up being published an embarrassing you, it doesn't allow comparison operators to think NA is a value.

It depends. The System.Timers.Timer has two modes of operation.

If SynchronizingObject is set to an ISynchronizeInvoke instance then the Elapsed event will execute on the thread hosting the synchronizing object. Usually these ISynchronizeInvoke instances are none other than plain old Control and Form instances that we are all familiar with. So in that case the Elapsed event is invoked on the UI thread and it behaves similar to the System.Windows.Forms.Timer. Otherwise, it really depends on the specific ISynchronizeInvoke instance that was used.

If SynchronizingObject is null then the Elapsed event is invoked on a ThreadPool thread and it behaves similar to the System.Threading.Timer. In fact, it actually uses a System.Threading.Timer behind the scenes and does the marshaling operation after it receives the timer callback if needed.

This happened to me because I was using:

app.datasource.url=jdbc:mysql://localhost/test

When I replaced url by jdbc-url then it worked:

app.datasource.jdbc-url=jdbc:mysql://localhost/test

The above problem can also be solved using ConstraintLayout through Guidelines.

Below is the snippet.

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_width="match_parent"
android:layout_height="match_parent">

<android.support.constraint.Guideline
    android:id="@+id/upperGuideLine"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"

    app:layout_constraintGuide_percent="0.68" />

<Gallery

    android:layout_height="wrap_content"

    app:layout_constraintGuide_percent="0.84" />

</android.support.constraint.ConstraintLayout>

I used it recently:

select 
substring(name,1,charindex(' ',name)-1) as Col1,
substring(name,charindex(' ',name)+1,len(name)) as Col2 
from TableName

You could do it if template is a react component.

Template.js

var React = require('react');

var Template = React.createClass({
    render: function(){
        return (<div>Mi HTML</div>);
    }
});

module.exports = Template;

MainComponent.js

var React = require('react');
var ReactDOM = require('react-dom');
var injectTapEventPlugin = require("react-tap-event-plugin");
var Template = require('./Template');

//Needed for React Developer Tools
window.React = React;

//Needed for onTouchTap
//Can go away when react 1.0 release
//Check this repo:
//https://github.com/zilverline/react-tap-event-plugin
injectTapEventPlugin();

var MainComponent = React.createClass({
    render: function() {
        return(
            <Template/>
        );
    }
});

// Render the main app react component into the app div.
// For more details see: https://facebook.github.io/react/docs/top-level-api.html#react.render
ReactDOM.render(
  <MainComponent />,
  document.getElementById('app')
 );

And if you are using Material-UI, for compatibility use Material-UI Components, no normal inputs.

find supports wildcard matches, just add a *:

find / -type d -name "ora10*"

You have multiple columns named the same thing in your inner query, so the error is raised in the outer query. If you get rid of the outer query, it should run, although still be confusing:

SELECT DISTINCT
    coaches.id,
    people.*,
    users.*,
    coaches.*
FROM "COACHES"
    INNER JOIN people ON people.id = coaches.person_id
    INNER JOIN users ON coaches.person_id = users.person_id
    LEFT OUTER JOIN organizations_users ON organizations_users.user_id = users.id
WHERE
    rownum <= 25

It would be much better (for readability and performance both) to specify exactly what fields you need from each of the tables instead of selecting them all anyways. Then if you really need two fields called the same thing from different tables, use column aliases to differentiate between them.

A quick true/false test of whether it will cast to [int]

[bool]($var -as [int] -is [int])

In some cases, static methods can be difficult to test, especially if they need to be mocked, which is why most mocking frameworks don't support them. I found this blog post to be very useful in determining how to mock static methods and classes.

On .Net Core 3.1 just follow Microsoft Doc that it is pretty simple: kestrel-aspnetcore-3.1

To summarize:

1. Add the below ConfigureServices section to CreateDefaultBuilder on Program.cs:

   // using Microsoft.Extensions.DependencyInjection;
   
   public static IHostBuilder CreateHostBuilder(string[] args) =>
       Host.CreateDefaultBuilder(args)
           .ConfigureServices((context, services) =>
           {
               services.Configure<KestrelServerOptions>(
                   context.Configuration.GetSection("Kestrel"));
           })
           .ConfigureWebHostDefaults(webBuilder =>
           {
               webBuilder.UseStartup<Startup>();
           });
   

2. Add the below basic config to appsettings.json file (more config options on Microsoft article):

   "Kestrel": {
       "EndPoints": {
           "Http": {
               "Url": "http://0.0.0.0:5002"
           }
       }
   }
   

3. Open CMD or Console on your project Publish/Debug/Release binaries folder and run:

   dotnet YourProject.dll
   

4. Enjoy exploring your site/api at your http://localhost:5002

Scikit-Learn is just telling you it doesn't recognise the argument "stratify", not that you're using it incorrectly. This is because the parameter was added in version 0.17 as indicated in the documentation you quoted.

So you just need to update Scikit-Learn.

<ui:include>

Most basic way is <ui:include>. The included content must be placed inside <ui:composition>.

Kickoff example of the master page /page.xhtml:

<!DOCTYPE html>
<html lang="en"
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://xmlns.jcp.org/jsf/core"
    xmlns:h="http://xmlns.jcp.org/jsf/html"
    xmlns:ui="http://xmlns.jcp.org/jsf/facelets">
    <h:head>
        <title>Include demo</title>
    </h:head>
    <h:body>
        <h1>Master page</h1>
        <p>Master page blah blah lorem ipsum</p>
        <ui:include src="/WEB-INF/include.xhtml" />
    </h:body>
</html>

The include page /WEB-INF/include.xhtml (yes, this is the file in its entirety, any tags outside <ui:composition> are unnecessary as they are ignored by Facelets anyway):

<ui:composition 
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://xmlns.jcp.org/jsf/core"
    xmlns:h="http://xmlns.jcp.org/jsf/html"
    xmlns:ui="http://xmlns.jcp.org/jsf/facelets">
    <h2>Include page</h2>
    <p>Include page blah blah lorem ipsum</p>
</ui:composition>
  

This needs to be opened by /page.xhtml. Do note that you don't need to repeat <html>, <h:head> and <h:body> inside the include file as that would otherwise result in invalid HTML.

You can use a dynamic EL expression in <ui:include src>. See also How to ajax-refresh dynamic include content by navigation menu? (JSF SPA).

<ui:define>/<ui:insert>

A more advanced way of including is templating. This includes basically the other way round. The master template page should use <ui:insert> to declare places to insert defined template content. The template client page which is using the master template page should use <ui:define> to define the template content which is to be inserted.

Master template page /WEB-INF/template.xhtml (as a design hint: the header, menu and footer can in turn even be <ui:include> files):

<!DOCTYPE html>
<html lang="en"
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://xmlns.jcp.org/jsf/core"
    xmlns:h="http://xmlns.jcp.org/jsf/html"
    xmlns:ui="http://xmlns.jcp.org/jsf/facelets">
    <h:head>
        <title><ui:insert name="title">Default title</ui:insert></title>
    </h:head>
    <h:body>
        <div id="header">Header</div>
        <div id="menu">Menu</div>
        <div id="content"><ui:insert name="content">Default content</ui:insert></div>
        <div id="footer">Footer</div>
    </h:body>
</html>

Template client page /page.xhtml (note the template attribute; also here, this is the file in its entirety):

<ui:composition template="/WEB-INF/template.xhtml"
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://xmlns.jcp.org/jsf/core"
    xmlns:h="http://xmlns.jcp.org/jsf/html"
    xmlns:ui="http://xmlns.jcp.org/jsf/facelets">

    <ui:define name="title">
        New page title here
    </ui:define>

    <ui:define name="content">
        <h1>New content here</h1>
        <p>Blah blah</p>
    </ui:define>
</ui:composition>

This needs to be opened by /page.xhtml. If there is no <ui:define>, then the default content inside <ui:insert> will be displayed instead, if any.

<ui:param>

You can pass parameters to <ui:include> or <ui:composition template> by <ui:param>.

<ui:include ...>
    <ui:param name="foo" value="#{bean.foo}" />
</ui:include>

<ui:composition template="...">
    <ui:param name="foo" value="#{bean.foo}" />
    ...
</ui:composition >

Inside the include/template file, it'll be available as #{foo}. In case you need to pass "many" parameters to <ui:include>, then you'd better consider registering the include file as a tagfile, so that you can ultimately use it like so <my:tagname foo="#{bean.foo}">. See also When to use <ui:include>, tag files, composite components and/or custom components?

You can even pass whole beans, methods and parameters via <ui:param>. See also JSF 2: how to pass an action including an argument to be invoked to a Facelets sub view (using ui:include and ui:param)?

Design hints

The files which aren't supposed to be publicly accessible by just entering/guessing its URL, need to be placed in /WEB-INF folder, like as the include file and the template file in above example. See also Which XHTML files do I need to put in /WEB-INF and which not?

There doesn't need to be any markup (HTML code) outside <ui:composition> and <ui:define>. You can put any, but they will be ignored by Facelets. Putting markup in there is only useful for web designers. See also Is there a way to run a JSF page without building the whole project?

The HTML5 doctype is the recommended doctype these days, "in spite of" that it's a XHTML file. You should see XHTML as a language which allows you to produce HTML output using a XML based tool. See also Is it possible to use JSF+Facelets with HTML 4/5? and JavaServer Faces 2.2 and HTML5 support, why is XHTML still being used.

CSS/JS/image files can be included as dynamically relocatable/localized/versioned resources. See also How to reference CSS / JS / image resource in Facelets template?

You can put Facelets files in a reusable JAR file. See also Structure for multiple JSF projects with shared code.

For real world examples of advanced Facelets templating, check the src/main/webapp folder of Java EE Kickoff App source code and OmniFaces showcase site source code.

You need the following permissions in your manifest file:

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>

Then you can use the following in your activity class:

WifiManager wifiManager = (WifiManager) this.getApplicationContext().getSystemService(Context.WIFI_SERVICE); 
wifiManager.setWifiEnabled(true);
wifiManager.setWifiEnabled(false);

Use the following to check if it's enabled or not

boolean wifiEnabled = wifiManager.isWifiEnabled()

I had the same issue when I was trying to connect to my IIS .NET Webservice from the Android emulator.

1. install npm install -g iisexpress-proxy
2. iisexpress-proxy 53990 to 9000 to proxy IIS express port to 9000 and access port 9000 from emulator like "http://10.0.2.2:9000"

the reason seems to be by default, IIS Express doesn't allow connections from network https://forums.asp.net/t/2125232.aspx?Bad+Request+Invalid+Hostname+when+accessing+localhost+Web+API+or+Web+App+from+across+LAN

When you run a program as a background process (by adding an & after it), e.g.:

python -m SimpleHTTPServer 8888 &

If the terminal window is still open you can do:

jobs

To get a list of all background jobs within the running shell's process.

It could look like this:

$ jobs
[1]+  Running                 python -m SimpleHTTPServer 8888 &

To kill a job, you can either do kill %1 to kill job "[1]", or do fg %1 to put the job in the foreground (fg) and then use ctrl-c to kill it. (Simply entering fg will put the last backgrounded process in the foreground).

With respect to SimpleHTTPServer it seems kill %1 is better than fg + ctrl-c. At least it doesn't protest with the kill command.

The above has been tested in Mac OS, but as far as I can remember it works just the same in Linux.

Update: For this to work, the web server must be started directly from the command line (verbatim the first code snippet). Using a script to start it will put the process out of reach of jobs.

simplexml_load_file() interprets an XML file (either a file on your disk or a URL) into an object. What you have in $feed is a string.

You have two options:

• Use file_get_contents() to get the XML feed as a string, and use e simplexml_load_string():

  $feed = file_get_contents('...');
  $items = simplexml_load_string($feed);
  

• Load the XML feed directly using simplexml_load_file():

  $items = simplexml_load_file('...');
  

Your live apps will not be taken down. Nothing will happen to anything that is live in the app store.

Once they formally expire, the only thing that will be impacted is your ability to sign code (and thus make new builds and provide updates).

Regarding your distribution certificate, once it expires, it simply disappears from the ‘Certificates, Identifier & Profiles’ section of Member Center. If you want to renew it before it expires, revoke the current certificate and you will get a button to request a new one.

Regarding the provisioning profile, don't worry about it before expiration, just keep using it. It's easy enough to just renew it once it expires.

The peace of mind is that nothing will happen to your live app in the store.

This question is asked in a lot of places in a lot of different ways. I originally answered it here but I feel it's relevant in this thread as well (since i ended up here when I was searching for an answer).

There is no one line solution to this problem, but this worked for my use case. The problem is, the 'View(context, attrs, defStyle)' constructor does not refer to an actual style, it wants an attribute. So, we will:

1. Define an attribute
2. Create a style that you want to use
3. Apply a style for that attribute on our theme
4. Create new instances of our view with that attribute

In 'res/values/attrs.xml', define a new attribute:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <attr name="customTextViewStyle" format="reference"/>
    ...
</resources>    

In res/values/styles.xml' I'm going to create the style I want to use on my custom TextView

<style name="CustomTextView">
    <item name="android:textSize">18sp</item>
    <item name="android:textColor">@color/white</item>
    <item name="android:paddingLeft">14dp</item>
</style>

In 'res/values/themes.xml' or 'res/values/styles.xml', modify the theme for your application / activity and add the following style:

<resources>
    <style name="AppBaseTheme" parent="android:Theme.Light">
        <item name="@attr/customTextViewStyle">@style/CustomTextView</item>
    </style>
    ... 
</resources>

Finally, in your custom TextView, you can now use the constructor with the attribute and it will receive your style

public class CustomTextView extends TextView {

    public CustomTextView(Context context) {
       super(context, null, R.attr.customTextView);
    }
}

It's worth noting that I repeatedly used customTextView in different variants and different places, but it is in no way required that the name of the view match the style or the attribute or anything. Also, this technique should work with any custom view, not just TextViews.

Here is my global module I use -

var Cookie = {   

   Create: function (name, value, days) {

       var expires = "";

        if (days) {
           var date = new Date();
           date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
           expires = "; expires=" + date.toGMTString();
       }

       document.cookie = name + "=" + value + expires + "; path=/";
   },

   Read: function (name) {

        var nameEQ = name + "=";
        var ca = document.cookie.split(";");

        for (var i = 0; i < ca.length; i++) {
            var c = ca[i];
            while (c.charAt(0) == " ") c = c.substring(1, c.length);
            if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length, c.length);
        }

        return null;
    },

    Erase: function (name) {

        Cookie.create(name, "", -1);
    }

};

Open the find and replace dialog (press CTRL+H).

Then select Regular expression in the 'Search Mode' section at the bottom.

In the Find what field enter this: [\r\n]+

In the Replace with: , 

There is a space after the comma.

This will also replace lines like

Apples

Apricots
Pear

Avocados
Bananas

Where there are empty lines.

If your lines have trailing blank spaces you should remove those first. The simplest way to achieve this is

EDIT -> Blank Operations -> Trim Trailing Space

OR

TextFX -> TextFX Edit -> Trim trailing spaces

Be sure to set the Search Mode to "Regular expression".

You can use this tool to create appropriate c# classes:

http://jsonclassgenerator.codeplex.com/

and when you will have classes created you can simply convert string to object:

    public static T ParseJsonObject<T>(string json) where T : class, new()
    {
        JObject jobject = JObject.Parse(json);
        return JsonConvert.DeserializeObject<T>(jobject.ToString());
    }

Here that classes: http://ge.tt/2KGtbPT/v/0?c

Just fix namespaces.

This is called Double checked locking mechanism, first, we will check whether the instance is created or not. If not then only we will synchronize the method and create the instance. It will drastically improve the performance of the application. Performing lock is heavy. So to avoid the lock first we need to check the null value. This is also thread safe and it is the best way to achieve the best performance. Please have a look at the following code.

public sealed class Singleton
{
    private static readonly object Instancelock = new object();
    private Singleton()
    {
    }
    private static Singleton instance = null;

    public static Singleton GetInstance
    {
        get
        {
            if (instance == null)
            {
                lock (Instancelock)
                {
                    if (instance == null)
                    {
                        instance = new Singleton();
                    }
                }
            }
            return instance;
        }
    }
}

If you have 32-bit Windows, this method is not working without following settings.

1. Run prompt cmd.exe (important : Run As Administrator)
2. type bcdedit.exe and run
3. Look at the "increaseuserva" params and there is no then write following statement
4. bcdedit /set increaseuserva 3072
5. and again step 2 and check params

We added this settings and this block started.

if exist "$(DevEnvDir)..\tools\vsvars32.bat" (
   call "$(DevEnvDir)..\tools\vsvars32.bat"
   editbin /largeaddressaware "$(TargetPath)"
)

More info - command increaseuserva: https://docs.microsoft.com/en-us/windows-hardware/drivers/devtest/bcdedit--set

The problem is you were calling print x.bye after you set x as a string. When you run x = hi() it runs hi() and sets the value of x to 5 (the value of bye; it does NOT set the value of x as a reference to the bye variable itself). EX: bye = 5; x = bye; bye = 4; print x; prints 5, not 4

Also, you don't have to run hi() twice, just run x = hi(), not hi();x=hi() (the way you had it it was running hi(), not doing anything with the resulting value of 5, and then rerunning the same hi() and saving the value of 5 to the x variable.

So full code should be

def hi():
    something
    something
    bye = 5
    return bye 
x = hi()
print x

If you wanted to return multiple variables, one option would be to use a list, or dictionary, depending on what you need.

ex:

def hi():
    something
    xyz = { 'bye': 7, 'foobar': 8}
    return xyz
x = hi()
print x['bye']

extern template is only needed if the template declaration is complete

This was hinted at in other answers, but I don't think enough emphasis was given to it.

What this means is that in the OPs examples, the extern template has no effect because the template definitions on the headers were incomplete:

• void f();: just declaration, no body
• class foo: declares method f() but has no definition

So I would recommend just removing the extern template definition in that particular case: you only need to add them if the classes are completely defined.

For example:

TemplHeader.h

template<typename T>
void f();

TemplCpp.cpp

template<typename T>
void f(){}

// Explicit instantiation for char.
template void f<char>();

Main.cpp

#include "TemplHeader.h"

// Commented out from OP code, has no effect.
// extern template void f<T>(); //is this correct?

int main() {
    f<char>();
    return 0;
}

compile and view symbols with nm:

g++ -std=c++11 -Wall -Wextra -pedantic -c -o TemplCpp.o TemplCpp.cpp
g++ -std=c++11 -Wall -Wextra -pedantic -c -o Main.o Main.cpp
g++ -std=c++11 -Wall -Wextra -pedantic -o Main.out Main.o TemplCpp.o
echo TemplCpp.o
nm -C TemplCpp.o | grep f
echo Main.o
nm -C Main.o | grep f

output:

TemplCpp.o
0000000000000000 W void f<char>()
Main.o
                 U void f<char>()

and then from man nm we see that U means undefined, so the definition did stay only on TemplCpp as desired.

All this boils down to the tradeoff of complete header declarations:

• upsides:
  • allows external code to use our template with new types
  • we have the option of not adding explicit instantiations if we are fine with object bloat
• downsides:
  • when developing that class, header implementation changes will lead smart build systems to rebuild all includers, which could be many many files
  • if we want to avoid object file bloat, we need not only to do explicit instantiations (same as with incomplete header declarations) but also add extern template on every includer, which programmers will likely forget to do

Further examples of those are shown at: Explicit template instantiation - when is it used?

Since compilation time is so critical in large projects, I would highly recommend incomplete template declarations, unless external parties absolutely need to reuse your code with their own complex custom classes.

And in that case, I would first try to use polymorphism to avoid the build time problem, and only use templates if noticeable performance gains can be made.

Tested in Ubuntu 18.04.

I found this listed as the new technique

This is very detailed

SELECT * FROM INFORMATION_SCHEMA.ROUTINES
WHERE ROUTINE_TYPE = N'PROCEDURE' and ROUTINE_SCHEMA = N'dbo' 
order by  LAST_ALTERED desc

SELECT * FROM INFORMATION_SCHEMA.ROUTINES
WHERE ROUTINE_TYPE = N'PROCEDURE' and ROUTINE_SCHEMA = N'dbo' 
order by  CREATED desc 


SELECT * FROM INFORMATION_SCHEMA.ROUTINES
WHERE ROUTINE_TYPE = N'FUNCTION' and ROUTINE_SCHEMA = N'dbo' 
order by  LAST_ALTERED desc

SELECT * FROM INFORMATION_SCHEMA.ROUTINES
WHERE ROUTINE_TYPE = N'FUNCTION' and ROUTINE_SCHEMA = N'dbo' 
order by  CREATED desc 

Here is an example that I built based on this page.

library(e1071); library(ggplot2)

mysvm      <- svm(Species ~ ., iris)
Predicted  <- predict(mysvm, iris)

mydf = cbind(iris, Predicted)
qplot(Petal.Length, Petal.Width, colour = Species, shape = Predicted, 
   data = iris)

This gives you the output. You can easily spot the misclassified species from this figure.

Set id for the textbox. ie,

<input type="text" name="txtJob" value="software engineer" id="txtJob"> 

In javascript

var jobValue = document.getElementById('txtJob').value

In Jquery

 var jobValue =  $("#txtJob").val();

No, Not at all.

Callbacks are simply Functions In JavaScript which are to be called and then executed after the execution of another function has finished. So how it happens?

Actually, In JavaScript, functions are itself considered as objects and hence as all other objects, even functions can be sent as arguments to other functions. The most common and generic use case one can think of is setTimeout() function in JavaScript.

Promises are nothing but a much more improvised approach of handling and structuring asynchronous code in comparison to doing the same with callbacks.

The Promise receives two Callbacks in constructor function: resolve and reject. These callbacks inside promises provide us with fine-grained control over error handling and success cases. The resolve callback is used when the execution of promise performed successfully and the reject callback is used to handle the error cases.

It has already been mentioned that hashmaps are O(n/m) in average, if n is the number of items and m is the size. It has also been mentioned that in principle the whole thing could collapse into a singly linked list with O(n) query time. (This all assumes that calculating the hash is constant time).

However what isn't often mentioned is, that with probability at least 1-1/n (so for 1000 items that's a 99.9% chance) the largest bucket won't be filled more than O(logn)! Hence matching the average complexity of binary search trees. (And the constant is good, a tighter bound is (log n)*(m/n) + O(1)).

All that's required for this theoretical bound is that you use a reasonably good hash function (see Wikipedia: Universal Hashing. It can be as simple as a*x>>m). And of course that the person giving you the values to hash doesn't know how you have chosen your random constants.

TL;DR: With Very High Probability the worst case get/put complexity of a hashmap is O(logn).

There actually is a way to do this that is allowed by C#. This gets back to C++, and rather violates the nice Object-Oriented structure of C#.

USE THIS METHOD WITH CAUTION!

Here's the way you declare and write your function with an optional parameter:

unsafe public void OptionalOutParameter(int* pOutParam = null)
{
    int lInteger = 5;
    // If the parameter is NULL, the caller doesn't care about this value.
    if (pOutParam != null) 
    { 
        // If it isn't null, the caller has provided the address of an integer.
        *pOutParam = lInteger; // Dereference the pointer and assign the return value.
    }
}

Then call the function like this:

unsafe { OptionalOutParameter(); } // does nothing
int MyInteger = 0;
unsafe { OptionalOutParameter(&MyInteger); } // pass in the address of MyInteger.

In order to get this to compile, you will need to enable unsafe code in the project options. This is a really hacky solution that usually shouldn't be used, but if you for some strange, arcane, mysterious, management-inspired decision, REALLY need an optional out parameter in C#, then this will allow you to do just that.

While dropping the columns from multiple tables, I faced following default constraints error. Similar issue appears if you need to change the datatype of column.

The object 'DF_TableName_ColumnName' is dependent on column 'ColumnName'.

To resolve this, I have to drop all those constraints first, by using following query

DECLARE @sql NVARCHAR(max)=''     
SELECT @SQL += 'Alter table ' + Quotename(tbl.name) + '  DROP constraint ' + Quotename(cons.name) + ';'
 FROM SYS.DEFAULT_CONSTRAINTS cons 
 JOIN   SYS.COLUMNS col ON col.default_object_id = cons.object_id
 JOIN   SYS.TABLES tbl ON tbl.object_id = col.object_id
 WHERE  col.[name] IN ('Column1','Column2')

--PRINT @sql
EXEC Sp_executesql @sql 

After that, I dropped all those columns (my requirement, not mentioned in this question)

DECLARE @sql NVARCHAR(max)='' 
SELECT @SQL += 'Alter table ' + Quotename(table_catalog)+ '.' + Quotename(table_schema) + '.'+ Quotename(TABLE_NAME) 
               + '  DROP column ' + Quotename(column_name) + ';'
FROM   information_schema.columns where COLUMN_NAME IN ('Column1','Column2')  
--PRINT @sql
EXEC Sp_executesql @sql 

I posted here in case someone find the same issue.

Happy Coding!

Main issue is that you first need to set the location of your x and y ticks. Also, it helps to use the more object-oriented interface to matplotlib. Namely, interact with the axes object directly.

import matplotlib.pyplot as plt
import numpy as np
column_labels = list('ABCD')
row_labels = list('WXYZ')
data = np.random.rand(4,4)
fig, ax = plt.subplots()
heatmap = ax.pcolor(data)

# put the major ticks at the middle of each cell, notice "reverse" use of dimension
ax.set_yticks(np.arange(data.shape[0])+0.5, minor=False)
ax.set_xticks(np.arange(data.shape[1])+0.5, minor=False)


ax.set_xticklabels(row_labels, minor=False)
ax.set_yticklabels(column_labels, minor=False)
plt.show()

Hope that helps.

On linux, you can run this command and see the result :

ps aux | grep "java"

This should work

return RedirectToAction("actionName", "controllerName", null);

use Select().Distinct()

for example

DBContext db = new DBContext();
var data= db.User_Food_UserIntakeFood .Select( ).Distinct();

There can be several reasons for this error message:

• Several processes have the database open at the same time (see the FAQ).

• There is a plugin to compress and encrypt the database. It doesn't allow to modify the DB.

• Lastly, another FAQ says: "Make sure that the directory containing the database file is also writable to the user executing the CGI script." I think this is because the engine needs to create more files in the directory.

• The whole filesystem might be read only, for example after a crash.

• On Unix systems, another process can replace the whole file.

It turns out this is actually possible, but not using the genuine Docker CE or EE version.

You can either use Red Hat's fork of docker with the '--add-registry' flag or you can build docker from source yourself with registry/config.go modified to use your own hard-coded default registry namespace/index.

This worked for me well :

 public static void main(String[] args) {
        launch(args);
    }

    @Override
    public void start(Stage primaryStage) throws IOException {

        FXMLLoader loader = new FXMLLoader(getClass().getResource("/fxml/TestDataGenerator.fxml"));
        loader.setClassLoader(getClass().getClassLoader());
        Parent root = loader.load();
        primaryStage.setScene(new Scene(root));
        primaryStage.show();
    }

In order to use word-wrap: break-word, you need to set a width (in px). For example:

div {
    width: 250px;
    word-wrap: break-word;
}

word-wrap is a CSS3 property, but it should work in all browsers, including IE 5.5-9.

MonoDevelop from: http://monodevelop.com/

There is no equivalent to Visual Studio. However, for writing C# on Mac or Linux, you can't get better than MonoDevelop.

The Mac build is pre beta. From the MonoDevelop site on Mac:

The Mac OS X port of MonoDevelop is under active development and has not seen a stable release yet. Recent work described by Michael Hutchinson has focussed on improving the usability and stability of Monodevelop on the Mac. This work will be released in MonoDevelop 2.2. Right now it's not finished, and is very much an alpha.

Most if not all of the suggested methods result in paths that cannot be used directly in some other terminal command if the path contains spaces. Ideally the results will have slashes prepended. This works for me on macOS:

find / -iname "*SEARCH TERM spaces are okay*" -print 2>&1  | grep -v denied |grep -v permitted |sed -E 's/\ /\\ /g'

Seems I found the solution. I hadn't properly noticed the keyAt(index) function.

So I'll go with something like this:

for(int i = 0; i < sparseArray.size(); i++) {
   int key = sparseArray.keyAt(i);
   // get the object by the key.
   Object obj = sparseArray.get(key);
}

Tejas Lagvankar wrote a nice post about this subject. Below are some key differences between Service and IntentService.

When to use?

• The Service can be used in tasks with no UI, but shouldn't be too long. If you need to perform long tasks, you must use threads within Service.

• The IntentService can be used in long tasks usually with no communication to Main Thread. If communication is required, can use Main Thread handler or broadcast intents. Another case of use is when callbacks are needed (Intent triggered tasks).

How to trigger?

• The Service is triggered by calling method startService().

• The IntentService is triggered using an Intent, it spawns a new worker thread and the method onHandleIntent() is called on this thread.

Triggered From

• The Service and IntentService may be triggered from any thread, activity or other application component.

Runs On

• The Service runs in background but it runs on the Main Thread of the application.

• The IntentService runs on a separate worker thread.

Limitations / Drawbacks

• The Service may block the Main Thread of the application.

• The IntentService cannot run tasks in parallel. Hence all the consecutive intents will go into the message queue for the worker thread and will execute sequentially.

When to stop?

• If you implement a Service, it is your responsibility to stop the service when its work is done, by calling stopSelf() or stopService(). (If you only want to provide binding, you don't need to implement this method).

• The IntentService stops the service after all start requests have been handled, so you never have to call stopSelf().
