If updating cURL doesn't fix it, updating NSS should do the trick.

Tried a lot of things, it did not help.

It get access in a simple way:

eval $(ssh-agent) > /dev/null
killall ssh-agent
eval `ssh-agent`
ssh-add ~/.ssh/id_rsa

Note that at the end of the ssh-add -L output must be not a path to the key, but your email.

After struggling for long I was finally able to resolve this issue on Windows, For me the User env variable GIT_SSH was set to point to

"C:\Program Files(x86)\WinScp\PuTTY\plink.exe"

which was installed along with WinScp. I changed the pointing to use default ssh.exe which comes with git-scm "C:\Program Files\Git\usr\bin\ssh.exe"

It usually happens when the certificate does not match with the host name.

The solution would be to contact the host and ask it to fix its certificate.
Otherwise you can turn off cURL's verification of the certificate, use the -k (or --insecure) option.
Please note that as the option said, it is insecure. You shouldn't use this option because it allows man-in-the-middle attacks and defeats the purpose of HTTPS.

More can be found in here: http://curl.haxx.se/docs/sslcerts.html

Check that you have the correct rights set on CA certificates bundle. Usually, that means read access for everyone to CA files in the /etc/ssl/certs directory, for instance /etc/ssl/certs/ca-certificates.crt.

You can see what files have been configured for you curl version with the

curl-config --configure

$ curl-config --configure
 '--prefix=/usr' 
 '--mandir=/usr/share/man' 
 '--disable-dependency-tracking' 
 '--disable-ldap' 
 '--disable-ldaps' 
 '--enable-ipv6' 
 '--enable-manual' 
 '--enable-versioned-symbols' 
 '--enable-threaded-resolver' 
 '--without-libidn' 
 '--with-random=/dev/urandom' 
 '--with-ca-bundle=/etc/ssl/certs/ca-certificates.crt' 
 'CFLAGS=-march=x86-64 -mtune=generic -O2 -pipe -fstack-protector --param=ssp-buffer-size=4' 'LDFLAGS=-Wl,-O1,--sort-common,--as-needed,-z,relro' 
 'CPPFLAGS=-D_FORTIFY_SOURCE=2'

Here you need read access to /etc/ssl/certs/ca-certificates.crt

$ curl-config --configure
 '--build' 'i486-linux-gnu' 
 '--prefix=/usr' 
 '--mandir=/usr/share/man' 
 '--disable-dependency-tracking' 
 '--enable-ipv6' 
 '--with-lber-lib=lber' 
 '--enable-manual' 
 '--enable-versioned-symbols' 
 '--with-gssapi=/usr' 
 '--with-ca-path=/etc/ssl/certs' 
 'build_alias=i486-linux-gnu' 
 'CFLAGS=-g -O2' 
 'LDFLAGS=' 
 'CPPFLAGS='

And the same here.

override is a C++11 keyword which means that a method is an "override" from a method from a base class. Consider this example:

   class Foo
   {
   public:
        virtual void func1();
   }

   class Bar : public Foo
   {
   public:
        void func1() override;
   }

If B::func1() signature doesn't equal A::func1() signature a compilation error will be generated because B::func1() does not override A::func1(), it will define a new method called func1() instead.

Use:

[self.view addSubview:obj.view];

As mentioned in this post, just use generator expressions like so:

numpy.fromiter((<some_func>(x) for x in <something>),<dtype>,<size of something>)

One of the first things you need to learn about SQL (and relational databases) is that you shouldn't store multiple values in a single field.

You should create another table and store one value per row.

This will make your querying easier, and your database structure better.

select 
    case when exists (select countryname from itemcountries where yourtable.id=itemcountries.id and countryname = @country) then 'national' else 'regional' end
from yourtable

function(e){ e.preventDefault();

and its opposite

function(e){ return true; }

cheers!

I did the trick. When set timeout, it works perfectly and sending all values.

    $(document).ready(function () {
        document.getElementById('btnSendMail').onclick = function () {
            setTimeout(function () {
                document.getElementById('btnSendMail').value = 'Sending…';
                document.getElementById('btnSendMail').disabled = true;
            }, 850);
        }
    });

@Mark Even though the compiler is allowed to optimize away the (stack based) temporary copy of the variable and gcc (in recent versions) is doing so, doesn't mean all compilers will always do so.

I just tested it with the compilers we use in our current project and 3 out of 4 do not optimize it.

Never assume the compiler gets it right, especially if the possibly faster, but never slower code is as easy to read.

If you don't have a really stupid implementation of one of the operators in your code:

Alwas prefer ++i over i++.

Please keep in mind that my answer has aged a lot.

There are other more technically sophisticated answers below, e.g.:

• neverpanic/google-font-download
• google-webfont-helper
• localfont

so don't let the fact that this is the currently accepted answer give you the impression that this is still the best one.

You can also now also download google's entire font set via on github at their google/font repository. They also provide a ~420MB zip snapshot of their fonts.

You first download your font selection as a zipped package, providing you with a bunch of true type fonts. Copy them somewhere public, somewhere you can link to from your css.

On the google webfont download page, you'll find a include link like so:

http://fonts.googleapis.com/css?family=Cantarell:400,700,400italic,700italic|Candal

It links to a CSS defining the fonts via a bunch of @font-face defintions.

Open it in a browser to copy and paste them into your own CSS and modify the urls to include the right font file and format types.

So this:

    @font-face {
      font-family: 'Cantarell';
      font-style: normal;
      font-weight: 700;
      src: local('Cantarell Bold'), local('Cantarell-Bold'), url(http://themes.googleusercontent.com/static/fonts/cantarell/v3/Yir4ZDsCn4g1kWopdg-ehHhCUOGz7vYGh680lGh-uXM.woff) format('woff');
    }

becomes this:

    /* Your local CSS File */
    @font-face {
        font-family: 'Cantarell';
        font-style: normal;
        font-weight: 700;
        src: local('Cantarell Bold'), local('Cantarell-Bold'), url(../font/Cantarell-Bold.ttf) format('truetype');
    }

As you can see, a downside of hosting the fonts on your own system this way is, that you restrict yourself to the true type format, whilst the google webfont service determines by the accessing device which formats will be transmitted.

Furthermore, I had to add a .htaccess file to my the directory holding the fonts containing mime types to avoid errors from popping up in Chrome Dev Tools.

For this solution, only true type is needed, but defining more does not hurt when you want to include different fonts as well, like font-awesome.

#.htaccess
AddType application/vnd.ms-fontobject .eot
AddType font/ttf .ttf
AddType font/otf .otf
AddType application/x-font-woff .woff

What could be the possible cause of this exception?

You may not have appropriate Jar in your class path.

How it could be removed?

By putting HTTPClient jar in your class path. If it's a webapp, copy Jar into WEB-INF/lib if it's standalone, make sure you have this jar in class path or explicitly set using -cp option

as the doc says,

Thrown if the Java Virtual Machine or a ClassLoader instance tries to load in the definition of a class (as part of a normal method call or as part of creating a new instance using the new expression) and no definition of the class could be found.

The searched-for class definition existed when the currently executing class was compiled, but the definition can no longer be found.

Edit:
If you are using a dependency management like Maven/Gradle (see the answer below) or SBT please use it to bring the httpclient jar for you.

Here's a short code that might help.

    <yourJFrameName> main = new <yourJFrameName>();    

    main.setVisible(true);
    this.dispose();

where...

main.setVisible(true);

will run the JFrame again.

this.dispose();

will terminate the running window.

Using pure java-script, here is a working code example

<input type="checkbox" name="fruit1" checked/>
<input type="checkbox" name="fruit2" checked />
<input type="checkbox" name="fruit3" checked />
<input type="checkbox" name="other1" checked />
<input type="checkbox" name="other2" checked />
<br>
<input type="button" name="check" value="count checked checkboxes name starts with fruit*" onClick="checkboxes();" />


<script>
function checkboxes()
{
var inputElems = document.getElementsByTagName("input"),
count = 0;
for (var i=0; i<inputElems.length; i++) {       
if (inputElems[i].type == "checkbox" && inputElems[i].checked == true && 
inputElems[i].name.indexOf('fruit') == 0) 
{
count++;

}

}
alert(count);
}
</script>

try to use heading, no need extra css

<h1 class="glyphicon glyphicon-plus"></h1>

Behind the curtain, enums are POJOs with a private constructor and a bunch of public static final values of the enum's type (see here for an example). In fact, up until Java5, it was considered best-practice to build your own enumeration this way, and Java5 introduced the enum keyword as a shorthand. See the source for Enum<T> to learn more.

So it should be no problem to write your own 'TypeSafeEnum' with a public static final array of constants, that are read by the constructor or passed to it.

Also, do yourself a favor and override equals, hashCode and toString, and if possible create a values method

The question is how to use such a dynamic enumeration... you can't read the value "PI=3.14" from a file to create enum MathConstants and then go ahead and use MathConstants.PI wherever you want...

In the System.Windows.Forms class, you can find more on the MSDN page for this here. Among other things you can control the message box text, title, default button, and icons. Since you didn't specify, if you are trying to do this in a webpage you should look at triggering the javascript alert("my message"); or confirm("my question"); functions.

If you want the list of all database sizes sorted, you can use :

SELECT * 
FROM   (SELECT table_schema AS `DB Name`, 
           ROUND(SUM(data_length + index_length) / 1024 / 1024, 1) AS `DB Size in MB`
        FROM   information_schema.tables 
        GROUP  BY `DB Name`) AS tmp_table 
ORDER  BY `DB Size in MB` DESC; 

Check out in here, worked well for me, with no limits in the output size, no omitted elements, even beyond 1000

Exporting large lists in R as .txt or .csv

you can use angular's filter https://docs.angularjs.org/api/ng/filter/filter

in your controller:

$filter('filter')(myArray, {'id':73}) 

or in your HTML

{{ myArray | filter : {'id':73} }}

git clone --filter from git 2.19 now works on GitHub (tested 2020-09-18, git 2.25.1)

This option was added together with an update to the remote protocol, and it truly prevents objects from being downloaded from the server.

To clone only objects required for d1 of this repository: https://github.com/cirosantilli/test-git-partial-clone I can do:

git clone \
  --depth 1 \
  --filter=blob:none \
  --no-checkout \
  https://github.com/cirosantilli/test-git-partial-clone \
;
cd test-git-partial-clone
git checkout master -- d1

I have covered this in more detail at: Git: How do I clone a subdirectory only of a Git repository?

I wanted a solution to have the output from stdout plus stderr written into a log file and stderr still on console. So I needed to duplicate the stderr output via tee.

This is the solution I found:

command 3>&1 1>&2 2>&3 1>>logfile | tee -a logfile

• First swap stderr and stdout
• then append the stdout to the log file
• pipe stderr to tee and append it also to the log file

Declare a global var:

var td

Then select your guiena pig <td> getting it by its id, if you want to change all of them then

window.onload = function () {
  td = document.getElementsByTagName("td"); 
}

Make a function to be triggered and a loop to change all of your desired td's

function trigger() {
    for(var x = 0; x < td.length; x++) { 
      td[x].className = "yournewclass"; 
    }
}

Go to your CSS Sheet:

.yournewclass:hover { background-color: #00ff00; }

And that is it, with this you are able to to make all your <td> tags get a background-color: #00ff00; when hovered by changing its css propriety directly (switching between css classes).

If a string must not contain @, every character must be another character than @:

/^[^@]*$/

This will match any string of any length that does not contain @.

Another possible solution would be to invert the boolean result of /@/.

Static indexes and small list?

Don't forget that if the list is small and the indexes don't change, as in your example, sometimes the best thing is to use sequence unpacking:

_,a1,a2,_,_,a3,_ = a

The performance is much better and you can also save one line of code:

 %timeit _,a1,b1,_,_,c1,_ = a
10000000 loops, best of 3: 154 ns per loop 
%timeit itemgetter(*b)(a)
1000000 loops, best of 3: 753 ns per loop
 %timeit [ a[i] for i in b]
1000000 loops, best of 3: 777 ns per loop
 %timeit map(a.__getitem__, b)
1000000 loops, best of 3: 1.42 µs per loop

You forgot to do source bin/activate where source is a executable name. Struck me first few times as well, easy to think that manual is telling "execute this from root of the environment folder".

No need to make activate executable via chmod.

If you want to run some custom filter logic you can create a function which takes the array element as an argument and returns true or false based on whether it should be in the search results. Then pass it to the filter instruction just like you do with the search object, for example:

JS:

$scope.filterFn = function(car)
{
    // Do some tests

    if(car.carDetails.doors > 2)
    {
        return true; // this will be listed in the results
    }

    return false; // otherwise it won't be within the results
};

HTML:

...
<article data-ng-repeat="result in results | filter:search | filter:filterFn" class="result">
...

As you can see you can chain many filters together, so adding your custom filter function doesn't force you to remove the previous filter using the search object (they will work together seamlessly).

I don't think that you really want an iframe, do you?

Unless you're doing something weird, you should be getting your results back as JSON or (in the worst case) XML, right?

For your white box / extra space issue, try

style="display: none;"

instead of

style="visibility: hidden;"

In SQL Plus:

VAR rc REFCURSOR
EXEC gokul_proc(1,'GOKUL', :rc);
print rc

Sometimes the columns will have commas within themselves, such as:

"Some item", "Another Item", "Also, One more item"

In these cases, splitting on "," will break some columns. Maybe an easier way, but I just made my own method (as a bonus, handles spaces after commas and returns an IList):

private IList<string> GetColumns(string columns)
{
    IList<string> list = new List<string>();

    if (!string.IsNullOrWhiteSpace(columns))
    {
        if (columns[0] != '\"')
        {
            // treat as just one item
            list.Add(columns);
        }
        else
        {
            bool gettingItemName = true;
            bool justChanged = false;
            string itemName = string.Empty;

            for (int index = 1; index < columns.Length; index++)
            {
                justChanged = false;
                if (subIndustries[index] == '\"')
                {
                    gettingItemName = !gettingItemName;
                    justChanged = true;
                }

                if ((gettingItemName == false) &&
                (justChanged == true))
                {
                    list.Add(itemName);
                    itemName = string.Empty;
                    justChanged = false;
                }

                if ((gettingItemName == true) && (justChanged == false))
                {
                    itemName += columns[index];
                }
            }
        }
    }

    return list;
}

It's been a little while since I coded with selenium, but your code looks ok to me. One thing to note is that if the element is not found, but the timeout is passed, I think the code will continue to execute. So you can do something like this:

boolean exists = driver.findElements(By.xpath("//*[@id='someID']")).size() != 0

What does the above boolean return? And are you sure selenium actually navigates to the expected page? (That may sound like a silly question but are you actually watching the pages change... selenium can be run remotely you know...)

In my case, its Password was longer than 100 characters. Setting it to a smaller character password worked.

Actually I am wondering is there a reference somewhere to that.

You can use the built-in filter function to filter dictionaries, lists, etc. based on specific conditions.

filtered_dict = dict(filter(lambda item: filter_str in item[0], d.items()))

The advantage is that you can use it for different data structures.

Now that you have provided your HTML sample, we're able to see that your XPath is slightly wrong. While it's valid XPath, it's logically wrong.

You've got:

//*[contains(@id, 'ctl00_btnAircraftMapCell')]//*[contains(@title, 'Select Seat')]

Which translates into:

Get me all the elements that have an ID that contains ctl00_btnAircraftMapCell. Out of these elements, get any child elements that have a title that contains Select Seat.

What you actually want is:

//a[contains(@id, 'ctl00_btnAircraftMapCell') and contains(@title, 'Select Seat')]

Which translates into:

Get me all the anchor elements that have both: an id that contains ctl00_btnAircraftMapCell and a title that contains Select Seat.

The selected answer makes it sound slightly more complex than it is, the following is what you need (install npm first on your system).

npm install -g elasticdump
elasticdump --input=http://mysrc.com:9200/my_index --output=http://mydest.com:9200/my_index --type=mapping
elasticdump --input=http://mysrc.com:9200/my_index --output=http://mydest.com:9200/my_index --type=data

You can skip the first elasticdump command for subsequent copies if the mappings remain constant.

I have just done a migration from AWS to Qbox.io with the above without any problems.

                    The mode can be index, delete or update.
                    'index': Add or replace documents on the destination index.
                    'delete': Delete documents on destination index.
                    'update': Use 'doc_as_upsert' option with bulk update API to do partial update.

                    Force use of destination index name (the actual output URL)
                    as destination while bulk writing to ES. Allows
                    leveraging Bulk API copying data inside the same
                    elasticsearch instance.
                    (default: false)
--timeout
                    Integer containing the number of milliseconds to wait for
                    a request to respond before aborting the request. Passed
                    directly to the request library. If used in bulk writing,
                    it will result in the entire batch not being written.
                    Mostly used when you don't care too much if you lose some
                    data when importing but rather have speed.
--skip
                    Integer containing the number of rows you wish to skip
                    ahead from the input transport.  When importing a large
                    index, things can go wrong, be it connectivity, crashes,
                    someone forgetting to `screen`, etc.  This allows you
                    to start the dump again from the last known line written
                    (as logged by the `offset` in the output).  Please be
                    advised that since no sorting is specified when the
                    dump is initially created, there's no real way to
                    guarantee that the skipped rows have already been
                    written/parsed.  This is more of an option for when
                    you want to get most data as possible in the index
                    without concern for losing some rows in the process,
                    similar to the `timeout` option.
--inputTransport
                    Provide a custom js file to us as the input transport
--outputTransport
                    Provide a custom js file to us as the output transport
--toLog
                    When using a custom outputTransport, should log lines
                    be appended to the output stream?
                    (default: true, except for `$`)

You probably need to do a git stash before you git pull, this is because it is reading your old config file. So do:

git stash
git pull
git commit -am <"say first commit">
git push

Also see git-stash(1) Manual Page.

First get Latitude and Longitude using Location and LocationManager class. Now try the code below for Get the city,address info

double latitude = location.getLatitude();
double longitude = location.getLongitude();
Geocoder gc = new Geocoder(this, Locale.getDefault());
try {
    List<Address> addresses = gc.getFromLocation(lat, lng, 1);
    StringBuilder sb = new StringBuilder();
    if (addresses.size() > 0) {
        Address address = addresses.get(0);
        for (int i = 0; i < address.getMaxAddressLineIndex(); i++)
            sb.append(address.getAddressLine(i)).append("\n");
            sb.append(address.getLocality()).append("\n");
            sb.append(address.getPostalCode()).append("\n");
            sb.append(address.getCountryName());
    }

City info is now in sb. Now convert the sb to String (using sb.toString() ).

Support for TLS 1.0 and 1.1 was dropped for PyPI. If your system does not use a more recent version, it could explain your error.

Could you try reinstalling pip system-wide, to update your system dependencies to a newer version of TLS?

This seems to be related to Unable to install Python libraries

See Dominique Barton's answer:

Apparently pip is trying to access PyPI via HTTPS (which is encrypted and fine), but with an old (insecure) SSL version. Your system seems to be out of date. It might help if you update your packages.

On Debian-based systems I'd try:

apt-get update && apt-get upgrade python-pip

On Red Hat Linux-based systems:

yum update python-pip # (or python2-pip, at least on Red Hat Linux 7)

On Mac:

sudo easy_install -U pip

You can also try to update openssl separately.

showInLegend is a series-specific option that can hide the series from the legend. If the requirement is to hide the legends completely then it is better to use enabled: false property as shown below:

legend: { enabled: false }

Two of the most widely used parsers are Expat and libxml.

If you are okay with using C++, there's Xerces-C++ too.

I am sure we have a lot of good answers here. But, I just thought of adding the way I have used enumerated types

package main

import "fmt"

type Enum interface {
    name() string
    ordinal() int
    values() *[]string
}

type GenderType uint

const (
    MALE = iota
    FEMALE
)

var genderTypeStrings = []string{
    "MALE",
    "FEMALE",
}

func (gt GenderType) name() string {
    return genderTypeStrings[gt]
}

func (gt GenderType) ordinal() int {
    return int(gt)
}

func (gt GenderType) values() *[]string {
    return &genderTypeStrings
}

func main() {
    var ds GenderType = MALE
    fmt.Printf("The Gender is %s\n", ds.name())
}

This is by far one of the idiomatic ways we could create Enumerated types and use in Go.

Edit:

Adding another way of using constants to enumerate

package main

import (
    "fmt"
)

const (
    // UNSPECIFIED logs nothing
    UNSPECIFIED Level = iota // 0 :
    // TRACE logs everything
    TRACE // 1
    // INFO logs Info, Warnings and Errors
    INFO // 2
    // WARNING logs Warning and Errors
    WARNING // 3
    // ERROR just logs Errors
    ERROR // 4
)

// Level holds the log level.
type Level int

func SetLogLevel(level Level) {
    switch level {
    case TRACE:
        fmt.Println("trace")
        return

    case INFO:
        fmt.Println("info")
        return

    case WARNING:
        fmt.Println("warning")
        return
    case ERROR:
        fmt.Println("error")
        return

    default:
        fmt.Println("default")
        return

    }
}

func main() {

    SetLogLevel(INFO)

}

When you create an implicit intent, the Android system finds the appropriate component to start by comparing the contents of the intent to the intent filters declared in the manifest file of other apps on the device. If the intent matches an intent filter, the system starts that component and delivers it the Intent object. If multiple intent filters are compatible, the system displays a dialog so the user can pick which app to use.

An intent filter is an expression in an app's manifest file that specifies the type of intents that the component would like to receive. For instance, by declaring an intent filter for an activity, you make it possible for other apps to directly start your activity with a certain kind of intent. Likewise, if you do not declare any intent filters for an activity, then it can be started only with an explicit intent.

According: Intents and Intent Filters

Modify the package you're using:

import org.apache.commons.codec.binary.Base64;

And then use it like this:

byte[] decoded = Base64.decodeBase64("YWJjZGVmZw==");
System.out.println(new String(decoded, "UTF-8") + "\n");

Expanding on mhawke's answer this is what I've implemented. It removes all the content of a folder but not the folder itself. Tested on Linux with files, folders and symbolic links, should work on Windows as well.

import os
import shutil

for root, dirs, files in os.walk('/path/to/folder'):
    for f in files:
        os.unlink(os.path.join(root, f))
    for d in dirs:
        shutil.rmtree(os.path.join(root, d))

Sys.sleep() will not work if the CPU usage is very high; as in other critical high priority processes are running (in parallel).

This code worked for me. Here I am printing 1 to 1000 at a 2.5 second interval.

for (i in 1:1000)
{
  print(i)
  date_time<-Sys.time()
  while((as.numeric(Sys.time()) - as.numeric(date_time))<2.5){} #dummy while loop
}

I've created a small plugin (available on NuGet) that allows you to add any (if supported by your terminal) color to your console output, without the limitations of the classic solutions.

It works by extending the String object and the syntax is very simple:

"colorize me".Pastel("#1E90FF");

Both foreground and background colors are supported.

There are a few other choices in case the Adobe ActiveX isn't what you're looking for (since Acrobat must be present on the user machine and you can't ship it yourself).

For creating the PDF preview, first have a look at some other discussions on the subject on StackOverflow:

• How can I take preview of documents?
• Get a preview jpeg of a pdf on windows?
• .NET open PDF in winform without external dependencies
• PDF Previewing and viewing

In the last two I talk about a few things you can try:

• You can get a commercial renderer (PDFViewForNet, PDFRasterizer.NET, ABCPDF, ActivePDF, XpdfRasterizer and others in the other answers...).
  Most are fairly expensive though, especially if all you care about is making a simple preview/thumbnails.

• In addition to Omar Shahine's code snippet, there is a CodeProject article that shows how to use the Adobe ActiveX, but it may be out of date, easily broken by new releases and its legality is murky (basically it's ok for internal use but you can't ship it and you can't use it on a server to produce images of PDF).

• You could have a look at the source code for SumatraPDF, an OpenSource PDF viewer for windows.

• There is also Poppler, a rendering engine that uses Xpdf as a rendering engine. All of these are great but they will require a fair amount of commitment to make make them work and interface with .Net and they tend to be be distributed under the GPL.

• You may want to consider using GhostScript as an interpreter because rendering pages is a fairly simple process.
  The drawback is that you will need to either re-package it to install it with your app, or make it a pre-requisite (or at least a part of your install process).
  It's not a big challenge, and it's certainly easier than having to massage the other rendering engines into cooperating with .Net.
  I did a small project that you will find on the Developer Express forums as an attachment.
  Be careful of the license requirements for GhostScript through.
  If you can't leave with that then commercial software is probably your only choice.

I had this problem, the solution was to look at the commit graph (using gitk) and see that I had the following:

*   commit I want to cherry-pick (x)
|\  
| * branch I want to cherry-pick to (y)
* | 
|/  
* common parent (x)

I understand now that I want to do

git cherry-pick -m 2 mycommitsha

This is because -m 1 would merge based on the common parent where as -m 2 merges based on branch y, that is the one I want to cherry-pick to.

Maybe you want more simple and short approach. This will clear all TextBoxes too. (Except TextBoxes inside Panel or GroupBox).

 foreach (TextBox textBox in Controls.OfType<TextBox>())
    textBox.Text = "";

Doesn't answer the "why" (has to be something w/ collapsing margin), but seems like the easiest/most logical way to do what you're trying to do would be to just add padding-top to the outer div:

http://jsfiddle.net/hpU5d/1/

Minor note - it shouldn't be necessary to set a div to display:block; unless there's something else in your code telling it not to be block.

no, but it runs fine on win64, and can create win64 .EXEs

The most easy way to do is copy innerHTML of that element to tmp variable and make it empty, then append new element, and after that copy back tmp variable to it. Here is an example I used to add jquery script to top of head.

var imported = document.createElement('script');
imported.src = 'http://code.jquery.com/jquery-1.7.1.js';
var tmpHead = document.head.innerHTML;
document.head.innerHTML = "";
document.head.append(imported);
document.head.innerHTML += tmpHead;

That simple :)

Chrome print is usually an extension page so there is no dom attachment happening in your existing page. You can trigger the print command using command line apis(window.print()) but then they have not provided apis for closing it becoz of vary reason like choosing print options, print machine,count etc.

Just because I haven't seen it here, if you are on MacOS or Linux, I suggest you add this to your PATH (in your bashrc etc):

node_modules/.bin

With this relative path entry, if you are sitting in the root folder of any node project, you can run any command line tool (eslint, gulp, etc. etc.) without worrying about "global installs" or npm run etc.

Once I did this, I've never installed a module globally.

Make sure you use the right doctype.

eg.

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">

or just

<!doctype html>

and also read and understand how compatibility modes and developer toolbar for IE work and set modes for IE:

`My vbs file path :

D:\QTP Practice\Driver\Testany.vbs'

objShell = CreateObject("Shell.Application")

objShell.ShellExecute "cmd.exe","/k echo test", "", "runas", 1

set x=createobject("wscript.shell")

wscript.sleep(2000)

x.sendkeys "CD\"&"{ENTER}"&"cd D:"&"{ENTER}"&"cd "&"QTP Practice\Driver"&"{ENTER}"&"Testany.vbs"&"{ENTER}"

--from google search and some tuning, working for me

Using styles.xml (value)

Very Easy solution , change colorPrimary as your choice and it will change color of button text of alert box.

<style name="MyAlertDialogStyle" parent="android:Theme.Material.Dialog.Alert">


        <!-- Used for the buttons -->
        <item name="colorAccent">@android:color/white</item>
        <!-- Used for the title and text -->
        <item name="android:textColorPrimary">@color/black</item>

        <!-- Used for the background -->

 @SuppressLint("ResourceAsColor")
            public boolean onJsAlert(WebView view, String url, String message, final JsResult result) {

                AlertDialog dialog = new AlertDialog.Builder(view.getContext(), R.style.MyAlertDialogStyle)

                        .setTitle("Royal Frolics")
                        .setIcon(R.mipmap.ic_launcher)
                        .setMessage(message)
                        .setPositiveButton("OK", (dialog1, which) -> {
                            //do nothing
                            result.confirm();
                        }).create();

                Objects.requireNonNull(dialog.getWindow()).getAttributes().windowAnimations = R.style.MyAlertDialogStyle;
                dialog.show();
                
                dialog.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(R.color.white);
                return true;

            }

This did the trick for me; full example:

HTML:

<a href="/my-popup.php" class="import">Click for my popup on same domain</a>

Javascript:

(function(){
    var doc = document;

    jQuery('.import').click(function(e){
        e.preventDefault();
        window.popup = window.open(jQuery(this).attr('href'), 'importwindow', 'width=500, height=200, top=100, left=200, toolbar=1');

        window.popup.onload = function() {
            window.popup.onbeforeunload = function(){
                doc.location.reload(true); //will refresh page after popup close
            }
        }
    });
})();

if you need to include the key of the document in the response, another alternative is:

async getMarker() {
    const snapshot = await firebase.firestore().collection('events').get()
    const documents = [];
    snapshot.forEach(doc => {
       documents[doc.id] = doc.data();
    });
    return documents;
}

First of all, don't use char* or char[N]. Use std::string, then everything else becomes so easy!

Examples,

std::string s = "Hello";
std::string greet = s + " World"; //concatenation easy!

Easy, isn't it?

Now if you need char const * for some reason, such as when you want to pass to some function, then you can do this:

some_c_api(s.c_str(), s.size()); 

assuming this function is declared as:

some_c_api(char const *input, size_t length);

Explore std::string yourself starting from here:

• Documentation of std::string

Hope that helps.

Excerpt from PostgreSQL documentation:

Restricting and cascading deletes are the two most common options. [...] CASCADE specifies that when a referenced row is deleted, row(s) referencing it should be automatically deleted as well.

This means that if you delete a category – referenced by books – the referencing book will also be deleted by ON DELETE CASCADE.

Example:

CREATE SCHEMA shire;

CREATE TABLE shire.clans (
    id serial PRIMARY KEY,
    clan varchar
);

CREATE TABLE shire.hobbits (
    id serial PRIMARY KEY,
    hobbit varchar,
    clan_id integer REFERENCES shire.clans (id) ON DELETE CASCADE
);

DELETE FROM clans will CASCADE to hobbits by REFERENCES.

sauron@mordor> psql
sauron=# SELECT * FROM shire.clans;
 id |    clan    
----+------------
  1 | Baggins
  2 | Gamgi
(2 rows)

sauron=# SELECT * FROM shire.hobbits;
 id |  hobbit  | clan_id 
----+----------+---------
  1 | Bilbo    |       1
  2 | Frodo    |       1
  3 | Samwise  |       2
(3 rows)

sauron=# DELETE FROM shire.clans WHERE id = 1 RETURNING *;
 id |  clan   
----+---------
  1 | Baggins
(1 row)

DELETE 1
sauron=# SELECT * FROM shire.hobbits;
 id |  hobbit  | clan_id 
----+----------+---------
  3 | Samwise  |       2
(1 row)

If you really need the opposite (checked by the database), you will have to write a trigger!

Here's an implementation in Javascript. My approach is to first convert the line segment into an infinite line then find the intersection point(s). From there I check if the point(s) found are on the line segment. The code is well documented, you should be able to follow along.

You can try out the code here on this live demo. The code was taken from my algorithms repo.

// Small epsilon value
var EPS = 0.0000001;

// point (x, y)
function Point(x, y) {
  this.x = x;
  this.y = y;
}

// Circle with center at (x,y) and radius r
function Circle(x, y, r) {
  this.x = x;
  this.y = y;
  this.r = r;
}

// A line segment (x1, y1), (x2, y2)
function LineSegment(x1, y1, x2, y2) {
  var d = Math.sqrt( (x1-x2)*(x1-x2) + (y1-y2)*(y1-y2) );
  if (d < EPS) throw 'A point is not a line segment';
  this.x1 = x1; this.y1 = y1;
  this.x2 = x2; this.y2 = y2;
}

// An infinite line defined as: ax + by = c
function Line(a, b, c) {
  this.a = a; this.b = b; this.c = c;
  // Normalize line for good measure
  if (Math.abs(b) < EPS) {
    c /= a; a = 1; b = 0;
  } else { 
    a = (Math.abs(a) < EPS) ? 0 : a / b;
    c /= b; b = 1; 
  }
}

// Given a line in standard form: ax + by = c and a circle with 
// a center at (x,y) with radius r this method finds the intersection
// of the line and the circle (if any). 
function circleLineIntersection(circle, line) {

  var a = line.a, b = line.b, c = line.c;
  var x = circle.x, y = circle.y, r = circle.r;

  // Solve for the variable x with the formulas: ax + by = c (equation of line)
  // and (x-X)^2 + (y-Y)^2 = r^2 (equation of circle where X,Y are known) and expand to obtain quadratic:
  // (a^2 + b^2)x^2 + (2abY - 2ac + - 2b^2X)x + (b^2X^2 + b^2Y^2 - 2bcY + c^2 - b^2r^2) = 0
  // Then use quadratic formula X = (-b +- sqrt(a^2 - 4ac))/2a to find the 
  // roots of the equation (if they exist) and this will tell us the intersection points

  // In general a quadratic is written as: Ax^2 + Bx + C = 0
  // (a^2 + b^2)x^2 + (2abY - 2ac + - 2b^2X)x + (b^2X^2 + b^2Y^2 - 2bcY + c^2 - b^2r^2) = 0
  var A = a*a + b*b;
  var B = 2*a*b*y - 2*a*c - 2*b*b*x;
  var C = b*b*x*x + b*b*y*y - 2*b*c*y + c*c - b*b*r*r;

  // Use quadratic formula x = (-b +- sqrt(a^2 - 4ac))/2a to find the 
  // roots of the equation (if they exist).

  var D = B*B - 4*A*C;
  var x1,y1,x2,y2;

  // Handle vertical line case with b = 0
  if (Math.abs(b) < EPS) {

    // Line equation is ax + by = c, but b = 0, so x = c/a
    x1 = c/a;

    // No intersection
    if (Math.abs(x-x1) > r) return [];

    // Vertical line is tangent to circle
    if (Math.abs((x1-r)-x) < EPS || Math.abs((x1+r)-x) < EPS)
      return [new Point(x1, y)];

    var dx = Math.abs(x1 - x);
    var dy = Math.sqrt(r*r-dx*dx);

    // Vertical line cuts through circle
    return [
      new Point(x1,y+dy),
      new Point(x1,y-dy)
    ];

  // Line is tangent to circle
  } else if (Math.abs(D) < EPS) {

    x1 = -B/(2*A);
    y1 = (c - a*x1)/b;

    return [new Point(x1,y1)];

  // No intersection
  } else if (D < 0) {

    return [];

  } else {

    D = Math.sqrt(D);

    x1 = (-B+D)/(2*A);
    y1 = (c - a*x1)/b;

    x2 = (-B-D)/(2*A);
    y2 = (c - a*x2)/b;

    return [
      new Point(x1, y1),
      new Point(x2, y2)
    ];

  }

}

// Converts a line segment to a line in general form
function segmentToGeneralForm(x1,y1,x2,y2) {
  var a = y1 - y2;
  var b = x2 - x1;
  var c = x2*y1 - x1*y2;
  return new Line(a,b,c);
}

// Checks if a point 'pt' is inside the rect defined by (x1,y1), (x2,y2)
function pointInRectangle(pt,x1,y1,x2,y2) {
  var x = Math.min(x1,x2), X = Math.max(x1,x2);
  var y = Math.min(y1,y2), Y = Math.max(y1,y2);
  return x - EPS <= pt.x && pt.x <= X + EPS &&
         y - EPS <= pt.y && pt.y <= Y + EPS;
}

// Finds the intersection(s) of a line segment and a circle
function lineSegmentCircleIntersection(segment, circle) {

  var x1 = segment.x1, y1 = segment.y1, x2 = segment.x2, y2 = segment.y2;
  var line = segmentToGeneralForm(x1,y1,x2,y2);
  var pts = circleLineIntersection(circle, line);

  // No intersection
  if (pts.length === 0) return [];

  var pt1 = pts[0];
  var includePt1 = pointInRectangle(pt1,x1,y1,x2,y2);

  // Check for unique intersection
  if (pts.length === 1) {
    if (includePt1) return [pt1];
    return [];
  }

  var pt2 = pts[1];
  var includePt2 = pointInRectangle(pt2,x1,y1,x2,y2);

  // Check for remaining intersections
  if (includePt1 && includePt2) return [pt1, pt2];
  if (includePt1) return [pt1];
  if (includePt2) return [pt2];
  return [];

}

works great as seen below:

<select class="form-control" id="selectTipoDocumento" formControlName="tipoDocumento" [compareWith]="equals"
          [class.is-valid]="this.docForm.controls['tipoDocumento'].valid &&
           (this.docForm.controls['tipoDocumento'].touched ||  this.docForm.controls['tipoDocumento'].dirty)"
          [class.is-invalid]="!this.docForm.controls['tipoDocumento'].valid &&
           (this.docForm.controls['tipoDocumento'].touched ||  this.docForm.controls['tipoDocumento'].dirty)">
            <option value="">Selecione um tipo</option>
            <option *ngFor="let tipo of tiposDocumento" [ngValue]="tipo">{{tipo?.nome}}</option>
          </select>

The python-shell module by extrabacon is a simple way to run Python scripts from Node.js with basic, but efficient inter-process communication and better error handling.

Installation: npm install python-shell.

Running a simple Python script:

var PythonShell = require('python-shell');

PythonShell.run('my_script.py', function (err) {
  if (err) throw err;
  console.log('finished');
});

Running a Python script with arguments and options:

var PythonShell = require('python-shell');

var options = {
  mode: 'text',
  pythonPath: 'path/to/python',
  pythonOptions: ['-u'],
  scriptPath: 'path/to/my/scripts',
  args: ['value1', 'value2', 'value3']
};

PythonShell.run('my_script.py', options, function (err, results) {
  if (err) 
    throw err;
  // Results is an array consisting of messages collected during execution
  console.log('results: %j', results);
});

Yes there are ways to load classes and to "unload" them later on. The trick is to implement your own classloader which resides between high level class loader (the System class loader) and the class loaders of the app server(s), and to hope that the app server's class loaders do delegate the classloading to the upper loaders.

A class is defined by its package, its name, and the class loader it originally loaded. Program a "proxy" classloader which is the first that is loaded when starting the JVM. Workflow:

• The program starts and the real "main"-class is loaded by this proxy classloader.
• Every class that then is normally loaded (i.e. not through another classloader implementation which could break the hierarchy) will be delegated to this class loader.
• The proxy classloader delegates java.x and sun.x to the system classloader (these must not be loaded through any other classloader than the system classloader).
• For every class that is replaceable, instantiate a classloader (which really loads the class and does not delegate it to the parent classloader) and load it through this.
• Store the package/name of the classes as keys and the classloader as values in a data structure (i.e. Hashmap).
• Every time the proxy classloader gets a request for a class that was loaded before, it returns the class from the class loader stored before.
• It should be enough to locate the byte array of a class by your class loader (or to "delete" the key/value pair from your data structure) and reload the class in case you want to change it.

Done right there should not come a ClassCastException or LinkageError etc.

For more informations about class loader hierarchies (yes, that's exactly what you are implementing here ;- ) look at "Server-Based Java Programming" by Ted Neward - that book helped me implementing something very similar to what you want.

Try like below with Gson Library.

Earlier Conversion List format were:

[Product [Id=1, City=Bengalore, Category=TV, Brand=Samsung, Name=Samsung LED, Type=LED, Size=32 inches, Price=33500.5, Stock=17.0], Product [Id=2, City=Bengalore, Category=TV, Brand=Samsung, Name=Samsung LED, Type=LED, Size=42 inches, Price=41850.0, Stock=9.0]]

and here the conversion source begins.

//** Note I have created the method toString() in Product class.

//Creating and initializing a java.util.List of Product objects
List<Product> productList = (List<Product>)productRepository.findAll();

//Creating a blank List of Gson library JsonObject
List<JsonObject> entities = new ArrayList<JsonObject>();

//Simply printing productList size
System.out.println("Size of productList is : " + productList.size());

//Creating a Iterator for productList
Iterator<Product> iterator = productList.iterator();

//Run while loop till Product Object exists.
while(iterator.hasNext()){

    //Creating a fresh Gson Object
    Gson gs = new Gson();

    //Converting our Product Object to JsonElement 
    //Object by passing the Product Object String value (iterator.next())
    JsonElement element = gs.fromJson (gs.toJson(iterator.next()), JsonElement.class);

    //Creating JsonObject from JsonElement
    JsonObject jsonObject = element.getAsJsonObject();

    //Collecting the JsonObject to List
    entities.add(jsonObject);

}

//Do what you want to do with Array of JsonObject
System.out.println(entities);

Converted Json Result is :

[{"Id":1,"City":"Bengalore","Category":"TV","Brand":"Samsung","Name":"Samsung LED","Type":"LED","Size":"32 inches","Price":33500.5,"Stock":17.0}, {"Id":2,"City":"Bengalore","Category":"TV","Brand":"Samsung","Name":"Samsung LED","Type":"LED","Size":"42 inches","Price":41850.0,"Stock":9.0}]

Hope this would help many guys!

My Scenario

def example():
    cl = [0, 1]
    def inner():
        #cl = [1, 2] # access this way will throw `reference before assignment`
        cl[0] = 1 
        cl[1] = 2   # these won't

    inner()

I have a project which uses LINQ-to-SQL for the data back-end. I have two main namespaces: Biz and Data. The LINQ data model lives in Data and is marked "internal"; the Biz namespace has public classes which wrap around the LINQ data classes.

So there's Data.Client, and Biz.Client; the latter exposes all relevant properties of the data object, e.g.:

private Data.Client _client;
public int Id { get { return _client.Id; } set { _client.Id = value; } }

The Biz objects have a private constructor (to force the use of factory methods), and an internal constructor which looks like this:

internal Client(Data.Client client) {
    this._client = client;
}

That can be used by any of the business classes in the library, but the front-end (UI) has no way of directly accessing the data model, ensuring that the business layer always acts as an intermediary.

This is the first time I've really used internal much, and it's proving quite useful.

The most likely explanations for that error are:

1. The file you are attempting to load is not an executable file. CreateProcess requires you to provide an executable file. If you wish to be able to open any file with its associated application then you need ShellExecute rather than CreateProcess.
2. There is a problem loading one of the dependencies of the executable, i.e. the DLLs that are linked to the executable. The most common reason for that is a mismatch between a 32 bit executable and a 64 bit DLL, or vice versa. To investigate, use Dependency Walker's profile mode to check exactly what is going wrong.

Reading down to the bottom of the code, I can see that the problem is number 1.

I strongly recommend using Java generics to specify what type of object is in that List, ie. List<Car>. If you have Cars and Trucks you can use a common superclass/interface like this List<Vehicle>.

However, you can use Spring's ReflectionUtils to make fields accessible, even if they are private like the below runnable example:

List<Object> list = new ArrayList<Object>();

list.add("some value");
list.add(3);

for(Object obj : list)
{
    Class<?> clazz = obj.getClass();

    Field field = org.springframework.util.ReflectionUtils.findField(clazz, "value");
    org.springframework.util.ReflectionUtils.makeAccessible(field);

    System.out.println("value=" + field.get(obj));
}

Running this has an output of:

value=[C@1b67f74
value=3

let is functional as its essentially a Proc. Also its cached.

One gotcha I found right away with let... In a Spec block that is evaluating a change.

let(:object) {FactoryGirl.create :object}

expect {
  post :destroy, id: review.id
}.to change(Object, :count).by(-1)

You'll need to be sure to call let outside of your expect block. i.e. you're calling FactoryGirl.create in your let block. I usually do this by verifying the object is persisted.

object.persisted?.should eq true

Otherwise when the let block is called the first time a change in the database will actually happen due to the lazy instantiation.

Update

Just adding a note. Be careful playing code golf or in this case rspec golf with this answer.

In this case, I just have to call some method to which the object responds. So I invoke the _.persisted?_ method on the object as its truthy. All I'm trying to do is instantiate the object. You could call empty? or nil? too. The point isn't the test but bringing the object ot life by calling it.

So you can't refactor

object.persisted?.should eq true

to be

object.should be_persisted 

as the object hasn't been instantiated... its lazy. :)

Update 2

leverage the let! syntax for instant object creation, which should avoid this issue altogether. Note though it will defeat a lot of the purpose of the laziness of the non banged let.

Also in some instances you might actually want to leverage the subject syntax instead of let as it may give you additional options.

subject(:object) {FactoryGirl.create :object}

I was having a problem getting my ASP.NET 5.0/MVC 6 app to serve static binary file types or browse virtual directories. It looks like this is now done in Configure() at startup. See http://docs.asp.net/en/latest/fundamentals/static-files.html for a quick primer.

Any Image is a collection of signals of various frequencies. The higher frequencies control the edges and the lower frequencies control the image content. Edges are formed when there is a sharp transition from one pixel value to the other pixel value like 0 and 255 in adjacent cell. Obviously there is a sharp change and hence the edge and high frequency. For sharpening an image these transitions can be enhanced further.

One way is to convolve a self made filter kernel with the image.

    import cv2
    import numpy as np

    image = cv2.imread('images/input.jpg')
    kernel = np.array([[-1,-1,-1], 
                       [-1, 9,-1],
                       [-1,-1,-1]])
    sharpened = cv2.filter2D(image, -1, kernel) # applying the sharpening kernel to the input image & displaying it.
    cv2.imshow('Image Sharpening', sharpened)
    cv2.waitKey(0)
    cv2.destroyAllWindows()

There is another method of subtracting a blurred version of image from bright version of it. This helps sharpening the image. But should be done with caution as we are just increasing the pixel values. Imagine a grayscale pixel value 190, which if multiplied by a weight of 2 makes if 380, but is trimmed of at 255 due to the maximum allowable pixel range. This is information loss and leads to washed out image.

    addWeighted(frame, 1.5, image, -0.5, 0, image);

Assume file is already created in the predefined directory with name "table.txt"

• 1) change the ownership for file :

  sudo chown username:username table.txt
  

• 2) change the mode of the file

  sudo chmod 777 table.txt
  

Now, try it should work!

this states that Account.deposit(Double.MAX_VALUE); it is setting deposit value to MAX value of Double dataType.to procced for running tests.

How about this method:

Set a field in the first object to a new value. If the same field in the second object has the same value, it's probably the same instance. Otherwise, exit as different.

Now set the field in the first object to a different new value. If the same field in the second object has changed to the different value, it's definitely the same instance.

Don't forget to set field in the first object back to it's original value on exit.

Problems?

There's another, simpler way to do this:

1. npm install Node@8 (saves Node 8 as dependency in package.json)
2. Your app will run using Node 8 for anyone - even Yarn users!

This works because node is just a package that ships node as its package binary. It just includes as node_module/.bin which means it only makes node available to package scripts. Not main shell.

See discussion on Twitter here: https://twitter.com/housecor/status/962347301456015360

Normally, pip will clean up after itself and remove the contents of the build directory. The only time it doesn't do this is if:

1. You used the --no-install option
2. You are using editable packages
3. The installation was cancelled or was otherwise interrupted.

In all other cases, you shouldn't have build directory that's clogging your environment.

Marc's answer is the approach I use for this, but for simplicity (and a friendlier API?) you can define a property in the collection base class if you have one such as:

public abstract class CollectionBase<T> : IList<T>
{
   ...

   public Type ElementType
   {
      get
      {
         return typeof(T);
      }
   }
}

I have found this approach useful, and is easy to understand for any newcomers to generics.

The onTokenRefresh() method is going to be called whenever a new token is generated. Upon app install, it will be generated immediately (as you have found to be the case). It will also be called when the token has changed.

According to the FirebaseCloudMessaging guide:

You can target notifications to a single, specific device. On initial startup of your app, the FCM SDK generates a registration token for the client app instance.

Source Link: https://firebase.google.com/docs/notifications/android/console-device#access_the_registration_token

This means that the token registration is per app. It sounds like you would like to utilize the token after a user is logged in. What I would suggest is that you save the token in the onTokenRefresh() method to internal storage or shared preferences. Then, retrieve the token from storage after a user logs in and register the token with your server as needed.

If you would like to manually force the onTokenRefresh(), you can create an IntentService and delete the token instance. Then, when you call getToken, the onTokenRefresh() method will be called again.

Example Code:

public class DeleteTokenService extends IntentService
{
    public static final String TAG = DeleteTokenService.class.getSimpleName();

    public DeleteTokenService()
    {
        super(TAG);
    }

    @Override
    protected void onHandleIntent(Intent intent)
    {
        try
        {
            // Check for current token
            String originalToken = getTokenFromPrefs();
            Log.d(TAG, "Token before deletion: " + originalToken);

            // Resets Instance ID and revokes all tokens.
            FirebaseInstanceId.getInstance().deleteInstanceId();

            // Clear current saved token
            saveTokenToPrefs("");

            // Check for success of empty token
            String tokenCheck = getTokenFromPrefs();
            Log.d(TAG, "Token deleted. Proof: " + tokenCheck);

            // Now manually call onTokenRefresh()
            Log.d(TAG, "Getting new token");
            FirebaseInstanceId.getInstance().getToken();
        }
        catch (IOException e)
        {
            e.printStackTrace();
        }
    }

    private void saveTokenToPrefs(String _token)
    {
        // Access Shared Preferences
        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
        SharedPreferences.Editor editor = preferences.edit();

        // Save to SharedPreferences
        editor.putString("registration_id", _token);
        editor.apply();
    }

    private String getTokenFromPrefs()
    {
        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
        return preferences.getString("registration_id", null);
    }
}

EDIT

FirebaseInstanceIdService

public class FirebaseInstanceIdService extends Service

This class is deprecated. In favour of overriding onNewToken in FirebaseMessagingService. Once that has been implemented, this service can be safely removed.

onTokenRefresh() is deprecated. Use onNewToken() in MyFirebaseMessagingService

public class MyFirebaseMessagingService extends FirebaseMessagingService {

@Override
public void onNewToken(String s) {
    super.onNewToken(s);
    Log.e("NEW_TOKEN",s);
    }

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);
    }
} 

I have used a trick to handle the apostrophe special character. When replacing ' for \' you need to place four backslashes before the apostrophe.

str.replaceAll("'","\\\\'");

I had the same problem, After lots of googling, I couldn't find out how to fix it.

Suddenly I noticed my stupid mistake :)

As mentioned in the docs, the last part of docker run is the command you want to run and its arguments after loading up the container.

NOT THE CONTAINER NAME !!!

That was my embarrassing mistake.

Below I provided you with the picture of my command line to see what I have done wrong.

And this is the fix as mentioned in the docs.

Here is a simple extension method:

    public static class StringBuilderExtensions
    {
        public static StringBuilder Replace(this StringBuilder sb, int position, string newString)
            => sb.Replace(position, newString.Length, newString);

        public static StringBuilder Replace(this StringBuilder sb, int position, int length, string newString)
            => (newString.Length <= length)
                ? sb.Remove(position, newString.Length).Insert(position, newString)
                : sb.Remove(position, length).Insert(position, newString.Substring(0, length));
    }

Use it like this:

var theString = new string(' ', 10);
var sb = new StringBuilder(theString);
sb.Replace(5, "foo");
return sb.ToString();

This is because you define your "doc" variable outside of your click event. The first time you click the button the doc variable contains a new jsPDF object. But when you click for a second time, this variable can't be used in the same way anymore. As it is already defined and used the previous time.

change it to:

$(function () {

    var specialElementHandlers = {
        '#editor': function (element,renderer) {
            return true;
        }
    };
 $('#cmd').click(function () {
        var doc = new jsPDF();
        doc.fromHTML(
            $('#target').html(), 15, 15, 
            { 'width': 170, 'elementHandlers': specialElementHandlers }, 
            function(){ doc.save('sample-file.pdf'); }
        );

    });  
});

and it will work.

You can use

.floatybox {
     display: inline-block;
     width: 123px;
}

If you only need to support browsers that have support for inline blocks. Inline blocks can have width, but are inline, like button elements.

Oh, and you might wnat to add vertical-align: top on the elements to make sure things line up

While I respect the answer from qkrijger explaining how you can work around this issue I think there is a lot more we can learn about what's going on here ...

To actually answer your question of "why" ... I think it would for helpful for you to understand how the docker stop command works and that all processes should be shutdown cleanly to prevent problems when you try to restart them (file corruption etc).

Problem: What if docker did start SSH from it's command and started RabbitMQ from your Docker file? "The docker stop command attempts to stop a running container first by sending a SIGTERM signal to the root process (PID 1) in the container." Which process is docker tracking as PID 1 that will get the SIGTERM? Will it be SSH or Rabbit?? "According to the Unix process model, the init process -- PID 1 -- inherits all orphaned child processes and must reap them. Most Docker containers do not have an init process that does this correctly, and as a result their containers become filled with zombie processes over time."

Answer: Docker simply takes that last CMD as the one that will get launched as the root process with PID 1 and get the SIGTERM from docker stop.

Suggested solution: You should use (or create) a base image specifically made for running more than one service, such as phusion/baseimage

It should be important to note that tini exists exactly for this reason, and as of Docker 1.13 and up, tini is officially part of Docker, which tells us that running more than one process in Docker IS VALID .. so even if someone claims to be more skilled regarding Docker, and insists that you absurd for thinking of doing this, know that you are not. There are perfectly valid situations for doing so.

The answer by Bryan Oakley above has a glitch as it has already been pointed out and the solution offered by Andrew Marshall though it does not carry the glitch, nevertheless it does not make it obvious for too much customization on the colors used.

As macOS Catalina asks for zsh to be the default shell from now on, I think several more people may want to customize their prompt and might be coming here for an answer. So, I thought I would try to give a broader summary and touch upon other very closely-related notions that allow more customization.

3-Digit Codes for Various Colors. First of all, here we can find 3-digit codes for various colors: https://unix.stackexchange.com/a/124409/194343. For example, 214 is some kind of orange color.

Foreground and Background. The other key information is that for Foreground and bacKground colors one can define what they want with F and K respectively. Source is zsh manual on visual effects: http://zsh.sourceforge.net/Doc/Release/Prompt-Expansion.html#Visual-effects

So, for example, the following two commands

autoload -U colors && colors
export PS1="%F{214}%K{000}%m%F{015}%K{000}:%F{039}%K{000}%~%F{015}%K{000}\$ "

present the hostname in orange with black background, followed by a colon in white with black background, followed by the current working directory in bright blue with black background, followed by the dollar sign in white with black background.

More related information is found below.

Prompt information on the right-hand side. For example, adding a timestamp. See https://superuser.com/a/1251045/290299. Of course, this can be color-coded, for example with some light blue/purple-ish color, like this:

RPROMPT="%F{111}%K{000}[%D{%f/%m/%y}|%@]"

Colors for ls. After reading the manual for ls, one for example can activate the colors for ls using the following two commands:

export CLICOLOR=1
export LSCOLORS=gafacadabaegedabagacad

Finally, as a last remark that I have not tested as I am happy with my configuration, another avenue might be for someone to install the port coreutils from MacPorts and then use gdircolors (source: https://unix.stackexchange.com/a/174596/194343). (I may edit this last part in the future as all the above are related pieces that make every-day life much more fun and easier to cope with.)

This usually occurs because either of the following are true:

• The certificate is self-signed and not added as a trusted certificate.
• The certificate is expired.
• The certificate is signed by a root certificate that's not installed on your machine.
• The certificate is signed using the fully qualified domain address of the server. Meaning: cannot use "xyzServerName" but instead must use "xyzServerName.ad.state.fl.us" because that's basically the server name as far as the SSL cert is concerned.
• A revocation list is probed, but cannot be found/used.
• The certificate is signed via intermediate CA certificate and server does not serve that intermediate certificate along with host certificate.

Try getting some information about the certificate of the server and see if you need to install any specific certs on your client to get it to work.

JSON content is basically represented as an associative array in JavaScript. You just need to loop over them to either read the key or the value:

    var JSON_Obj = { "one":1, "two":2, "three":3, "four":4, "five":5 };

    // Read key
    for (var key in JSON_Obj) {
       console.log(key);
       console.log(JSON_Obj[key]);
   }

Here's a concise version that works with class method callbacks and with regular function callbacks. In this example, to show how parameters are handled, the callback function takes two parameters: bool and int.

class Caller {
  template<class T> void addCallback(T* const object, void(T::* const mf)(bool,int))
  {
    using namespace std::placeholders; 
    callbacks_.emplace_back(std::bind(mf, object, _1, _2));
  }
  void addCallback(void(* const fun)(bool,int)) 
  {
    callbacks_.emplace_back(fun);
  }
  void callCallbacks(bool firstval, int secondval) 
  {
    for (const auto& cb : callbacks_)
      cb(firstval, secondval);
  }
private:
  std::vector<std::function<void(bool,int)>> callbacks_;
}

class Callee {
  void MyFunction(bool,int);
}

//then, somewhere in Callee, to add the callback, given a pointer to Caller `ptr`

ptr->addCallback(this, &Callee::MyFunction);

//or to add a call back to a regular function
ptr->addCallback(&MyRegularFunction);

This restricts the C++11-specific code to the addCallback method and private data in class Caller. To me, at least, this minimizes the chance of making mistakes when implementing it.

You can put @JsonSerialize(using = CustomDateSerializer.class) over any date field of object to be serialized.

public class CustomDateSerializer extends SerializerBase<Date> {

    public CustomDateSerializer() {
        super(Date.class, true);
    }

    @Override
    public void serialize(Date value, JsonGenerator jgen, SerializerProvider provider)
        throws IOException, JsonProcessingException {
        SimpleDateFormat formatter = new SimpleDateFormat("EEE MMM dd yyyy HH:mm:ss 'GMT'ZZZ (z)");
        String format = formatter.format(value);
        jgen.writeString(format);
    }

}

Because that gtab82 table isn't in your FROM or JOIN clause. You refer gtab82 table in these cases: gtab82.memno and gtab82.memacid

I prefer this one, it is shorter:

find . -type f -print0|xargs -0 ls -drt|tail -n 1

RealVNC 5.0.x now offers a VNCViewer that will do dual displays on Windows without having to buy a license. (Licensing now covers the SERVER portion of their tools).

The canvas DOM element has .height and .width properties that correspond to the height="…" and width="…" attributes. Set them to numeric values in JavaScript code to resize your canvas. For example:

var canvas = document.getElementsByTagName('canvas')[0];
canvas.width  = 800;
canvas.height = 600;

Note that this clears the canvas, though you should follow with ctx.clearRect( 0, 0, ctx.canvas.width, ctx.canvas.height); to handle those browsers that don't fully clear the canvas. You'll need to redraw of any content you wanted displayed after the size change.

Note further that the height and width are the logical canvas dimensions used for drawing and are different from the style.height and style.width CSS attributes. If you don't set the CSS attributes, the intrinsic size of the canvas will be used as its display size; if you do set the CSS attributes, and they differ from the canvas dimensions, your content will be scaled in the browser. For example:

// Make a canvas that has a blurry pixelated zoom-in
// with each canvas pixel drawn showing as roughly 2x2 on screen
canvas.width  = 400;
canvas.height = 300; 
canvas.style.width  = '800px';
canvas.style.height = '600px';

See this live example of a canvas that is zoomed in by 4x.

var c = document.getElementsByTagName('canvas')[0];_x000D_
var ctx = c.getContext('2d');_x000D_
ctx.lineWidth   = 1;_x000D_
ctx.strokeStyle = '#f00';_x000D_
ctx.fillStyle   = '#eff';_x000D_

ctx.strokeRect( 10.5, 10.5, 20, 20 );_x000D_
ctx.fillRect(   40, 10.5, 20, 20 );_x000D_
ctx.strokeRect( 40, 10.5, 20, 20 );_x000D_
ctx.fillRect(   70, 10, 20, 20 );_x000D_
ctx.strokeRect( 70, 10, 20, 20 );_x000D_

ctx.strokeStyle = '#fff';_x000D_
ctx.strokeRect( 10.5, 10.5, 20, 20 );_x000D_
ctx.strokeRect( 40, 10.5, 20, 20 );_x000D_
ctx.strokeRect( 70, 10, 20, 20 );

I am assuming that you have enough permissions to create this directory.

To fix your problem, you can either ssh to some other location:

ssh [email protected]

and accept new key - it will create directory ~/.ssh and known_hosts underneath, or simply create it manually using

mkdir ~/.ssh
chmod 700 ~/.ssh

Note that chmod 700 is an important step!

After that, ssh-keygen should work without complaints.

Because JSON directly supports the \uxxxx syntax the first thing that comes into my mind is:

$unicodeChar = '\u1000';
echo json_decode('"'.$unicodeChar.'"');

Another option would be to use mb_convert_encoding()

echo mb_convert_encoding('က', 'UTF-8', 'HTML-ENTITIES');

or make use of the direct mapping between UTF-16BE (big endian) and the Unicode codepoint:

echo mb_convert_encoding("\x10\x00", 'UTF-8', 'UTF-16BE');

Change Minute to be 0. That's it :)

Note: you can check your "crons" in http://cronchecker.net/

Example

for mysqli connect;

<?php

$host       = "host";
$user       = "user";
$pass       = "pss";
$database   = "db_name";


$connect = new mysqli($host, $user, $pass, $database);  

// Actual code starts here Dont forget to change db_name !!
$sql = "SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES
    WHERE TABLE_SCHEMA = 'db_name' 
    AND ENGINE = 'MyISAM'";

$rs = $connect->query($sql);

while($row = $rs->fetch_array())
{
    $tbl = $row[0];
    $sql = "ALTER TABLE `$tbl` ENGINE=INNODB";
    $connect->query($sql);
} ?>

after cloning a fork you have to explicitly add a remote upstream, with git add remote "the original repo you forked from". This becomes your upstream, you mostly fetch and merge from your upstream. Any other business such as pushing from your local to upstream should be done using pull request.

table td{
  color:#0000ff;
}

<table>
  <tbody>
    <tr>
    <td>
      <select name="test">
        <option value="Basic">Basic : $30.00 USD - yearly</option>
        <option value="Sustaining">Sustaining : $60.00 USD - yearly</option>
        <option value="Supporting">Supporting : $120.00 USD - yearly</option>
      </select>
    </td>
    </tr>
  </tbody>
</table>

String.Concat transforms DBNull and null values to an empty string.

public string GetCustomerNumber(Guid id)
{
   object accountNumber =  
          (object)DBSqlHelperFactory.ExecuteScalar(connectionStringSplendidCRM, 
                                CommandType.StoredProcedure, 
                                "spx_GetCustomerNumber", 
                                new SqlParameter("@id", id));

    return String.Concat(accountNumber);

 }

However, I think you lose something on code understandability

Loop through your list and do a contains or startswith.

ArrayList<String> resList = new ArrayList<String>();
String searchString = "bea";

for (String curVal : list){
  if (curVal.contains(searchString)){
    resList.add(curVal);
  }
}

You can wrap that in a method. The contains checks if its in the list. You could also go for startswith.

How things change in a year. In addition to the header attribute in place of xhr.setRequestHeader, current jQuery (1.7.2+) includes a username and password attribute with the $.ajax call.

$.ajax
({
  type: "GET",
  url: "index1.php",
  dataType: 'json',
  username: username,
  password: password,
  data: '{ "comment" }',
  success: function (){
    alert('Thanks for your comment!'); 
  }
});

EDIT from comments and other answers: To be clear - in order to preemptively send authentication without a 401 Unauthorized response, instead of setRequestHeader (pre -1.7) use 'headers':

$.ajax
({
  type: "GET",
  url: "index1.php",
  dataType: 'json',
  headers: {
    "Authorization": "Basic " + btoa(USERNAME + ":" + PASSWORD)
  },
  data: '{ "comment" }',
  success: function (){
    alert('Thanks for your comment!'); 
  }
});

You should have a look on the -regextype argument of find, see manpage:

      -regextype type
          Changes the regular expression syntax understood by -regex and -iregex 
          tests which occur later on the command line.  Currently-implemented  
          types  are  emacs (this is the default), posix-awk, posix-basic, 
          posix-egrep and posix-extended. 

I guess the emacs type doesn't support the [[:digit:]] construct. I tried it with posix-extended and it worked as expected:

find -regextype posix-extended -regex '.*[1234567890]'
find -regextype posix-extended -regex '.*[[:digit:]]'

Simply use Path.GetFileName

Here - Extract folder name from the full path of a folder:

string folderName = Path.GetFileName(@"c:\projects\root\wsdlproj\devlop\beta2\text");//Return "text"

Here is some extra - Extract folder name from the full path of a file:

string folderName = Path.GetFileName(Path.GetDirectoryName(@"c:\projects\root\wsdlproj\devlop\beta2\text\GTA.exe"));//Return "text"

If you are unaware of the position to replace, use list iterator to find and replace element ListIterator.set(E e)

ListIterator<String> iterator = list.listIterator();
while (iterator.hasNext()) {
     String next = iterator.next();
     if (next.equals("Two")) {
         //Replace element
         iterator.set("New");
     }
 }

If your issue is with linked servers, you need to look at a few things.

First, your users need to have delegation enabled and if the only thing that's changed, it'l likely they do. Otherwise you can uncheck the "Account is sensitive and cannot be delegated" checkbox is the user properties in AD.

Second, your service account(s) must be trusted for delegation. Since you recently changed your service account I suspect this is the culprit. (http://technet.microsoft.com/en-us/library/cc739474(v=ws.10).aspx)

You mentioned that you might have some SPN issues, so be sure to set the SPN for both endpoints, otherwise you will not be able to see the delegation tab in AD. Also make sure you're in advanced view in "Active Directory Users and Computers."

If you still do not see the delegation tab, even after correcting your SPN, make sure your domain not in 2000 mode. If it is, you can "raise domain function level."

At this point, you can now mark the account as trusted for delegation:

In the details pane, right-click the user you want to be trusted for delegation, and click Properties.

Click the Delegation tab, select the Account is trusted for delegation check box, and then click OK.

Finally you will also need to set all the machines as trusted for delegation.

Once you've done this, reconnect to your sql server and test your liked servers. They should work.

You can use like this one. Place it inside AppDelegate.swift.

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        // Override point for customization after application launch.

        UINavigationBar.appearance().translucent = false
        UINavigationBar.appearance().barTintColor = UIColor(rgba: "#2c8eb5")
        UINavigationBar.appearance().tintColor = UIColor.whiteColor()
        UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName:UIColor.whiteColor()]

        return true
    }

That won't work if the string contains more than one match... try this:

echo "/x/y/z/x" | awk '{ gsub("/", "_") ; system( "echo "  $0) }'

or better (if the echo isn't a placeholder for something else):

echo "/x/y/z/x" | awk '{ gsub("/", "_") ; print $0 }'

In your case you want to make a copy of the value before changing it:

echo "/x/y/z/x" | awk '{ c=$0; gsub("/", "_", c) ; system( "echo " $0 " " c )}'

Had a similar problem. My solution was to give the inner table a fixed height of 1px and set the height of the td in the inner table to 100%. Against all odds, it works fine, tested in IE, Chrome and FF!

There's a few gems in the 'C' spec that Java dropped for pragmatic reasons but which are slowly creeping back with developer demand (closures, etc).

I mention a first one because it's related to this discussion; the adherence of pointer values to unsigned integer arithmetic. And, in relation to this thread topic, the difficulty of maintaining Unsigned semantics in the Signed world of Java.

I would guess if one were to get a Dennis Ritchie alter ego to advise Gosling's design team it would have suggested giving Signed's a "zero at infinity", so that all address offset requests would first add their ALGEBRAIC RING SIZE to obviate negative values.

That way, any offset thrown at the array can never generate a SEGFAULT. For example in an encapsulated class which I call RingArray of doubles that needs unsigned behaviour - in "self rotating loop" context:

// ...
// Housekeeping state variable
long entrycount;     // A sequence number
int cycle;           // Number of loops cycled
int size;            // Active size of the array because size<modulus during cycle 0
int modulus;         // Maximal size of the array

// Ring state variables
private int head;   // The 'head' of the Ring
private int tail;   // The ring iterator 'cursor'
// tail may get the current cursor position
// and head gets the old tail value
// there are other semantic variations possible

// The Array state variable
double [] darray;    // The array of doubles

// somewhere in constructor
public RingArray(int modulus) {
    super();
    this.modulus = modulus;
    tail =  head =  cycle = 0;
    darray = new double[modulus];
// ...
}
// ...
double getElementAt(int offset){
    return darray[(tail+modulus+offset%modulus)%modulus];
}
//  remember, the above is treating steady-state where size==modulus
// ...

The above RingArray would never ever 'get' from a negative index, even if a malicious requestor tried to. Remember, there are also many legitimate requests for asking for prior (negative) index values.

NB: The outer %modulus de-references legitimate requests whereas the inner %modulus masks out blatant malice from negatives more negative than -modulus. If this were to ever appear in a Java +..+9 || 8+..+ spec, then the problem would genuinely become a 'programmer who cannot "self rotate" FAULT'.

I'm sure the so-called Java unsigned int 'deficiency' can be made up for with the above one-liner.

PS: Just to give context to above RingArray housekeeping, here's a candidate 'set' operation to match the above 'get' element operation:

void addElement(long entrycount,double value){ // to be called only by the keeper of entrycount
    this.entrycount= entrycount;
    cycle = (int)entrycount/modulus;
    if(cycle==0){                       // start-up is when the ring is being populated the first time around
        size = (int)entrycount;         // during start-up, size is less than modulus so use modulo size arithmetic
        tail = (int)entrycount%size;    //  during start-up
    }
    else {
        size = modulus;
        head = tail;
        tail = (int)entrycount%modulus; //  after start-up
    }
    darray[head] = value;               //  always overwrite old tail
}

function getDetailedObject(inputObject) {
    var detailedObject = {}, properties;

    do {
        properties = Object.getOwnPropertyNames( inputObject );
        for (var o in properties) {
            detailedObject[properties[o]] = inputObject[properties[o]];
        }
    } while ( inputObject = Object.getPrototypeOf( inputObject ) );

    return detailedObject;
}

This will get all properties and their values (inherited or own, enumerable or not) in a new object. original object is untouched. Now new object can be traversed using

var obj = { 'b': '4' }; //example object
var detailedObject = getDetailedObject(obj);
for(var o in detailedObject) {
    console.log('key: ' + o + '   value: ' + detailedObject[o]);
}

I think You are trying to use the normal URL of video Like this :

Copying Direct URL from YouTube

That doesn't let you display the content on other domains.To Tackle this up , You should use the Copy Embed Code feature provided by the YouTube itself .Like this :

That would free you up from any issues .

For the above Scenario :

• Go to Youtube Video

• Copy Embed Code

• Paste that into your Code ( Make sure you Escape all the " ( Inverted Commas) by \" .

I ran into a similar problem on a Linux server, where two versions of Boost have been installed. One is the precompiled 1.53.0 version which counts as old in 2018; it's in /usr/include and /usr/lib64. The version I want to use is 1.67.0, as a minimum version of 1.65.1 is required for another C++ library I'm installing; it's in /opt/boost, which has include and lib subdirectories. As suggested in previous answers, I set variables in CMakeLists.txt to specify where to look for Boost 1.67.0 as follows

include_directories(/opt/boost/include/)
include_directories(/opt/boost/lib/)
set(BOOST_ROOT /opt/boost/)
set(BOOST_INCLUDEDIR /opt/boost/include/)
set(BOOST_LIBRARYDIR /opt/boost/lib)
set(Boost_NO_SYSTEM_PATHS TRUE)
set(Boost_NO_BOOST_CMAKE TRUE)

But CMake doesn't honor those changes. Then I found an article online: CMake can use a local Boost, and realized that I need to change the variables in CMakeCache.txt. There I found that the Boost-related variables are still pointing to the default Boost 1.53.0, so no wonder CMake doesn't honor my changes in CMakeLists.txt. Then I set the Boost-related variables in CMakeCache.txt

Boost_DIR:PATH=Boost_DIR-NOTFOUND
Boost_INCLUDE_DIR:PATH=/opt/boost/include/
Boost_LIBRARY_DIR_DEBUG:PATH=/opt/boost/lib
Boost_LIBRARY_DIR_RELEASE:PATH=/opt/boost/lib

I also changed the variables pointing to the non-header, compiled parts of the Boost library to point to the version I want. Then CMake successfully built the library that depends on a recent version of Boost.

For the upgrade scenario specifically an alternative approach might be to have a web service that delivers the current version number and check that instead of downloading the entire apk just to check its version. It would save some bandwidth, be a little more performant (much faster to download than an apk if the whole apk isn't needed most of the time) and much simpler to implement.

In the simplest form you could have a simple text file on your server... http://some-place.com/current-app-version.txt

Inside of that text file have something like

3.1.4

and then download that file and check against the currently installed version.

Building a more advanced solution to that would be to implement a proper web service and have an api call at launch which could return some json, i.e. http://api.some-place.com/versionCheck:

{
    "current_version": "3.1.4"
}

Top voted answer is awesome, but helping out the rookies like me, here is how to create the .gitignore file, edit it, save it, remove the files you might have already added to git, then push up the file to Github.

Create the .gitignore file

To create a .gitignore file, you can just touch the file which creates a blank file with the specified name. We want to create the file named .gitignore so we can use the command:

touch .gitignore

Ignore the files

Now you have to add the line which tells git to ignore the DS Store files to your .gitignore. You can use the nano editor to do this.

nano .gitignore

Nano is nice because it includes instructions on how to get out of it. (Ctrl-O to save, Ctrl-X to exit)

Copy and paste some of the ideas from this Github gist which lists some common files to ignore. The most important ones, to answer this question, would be:

# OS generated files #
######################
.DS_Store
.DS_Store?

The # are comments, and will help you organize your file as it grows.

This Github article also has some general ideas and guidelines.

Remove the files already added to git

Finally, you need to actually remove those DS Store files from your directory.

Use this great command from the top voted answer. This will go through all the folders in your directory, and remove those files from git.

find . -name .DS_Store -print0 | xargs -0 git rm -f --ignore-unmatch

Push .gitignore up to Github

Last step, you need to actually commit your .gitignore file.

git status

git add .gitignore

git commit -m '.DS_Store banished!'

Add this to the top of your script:

args<-commandArgs(TRUE)

Then you can refer to the arguments passed as args[1], args[2] etc.

Then run

Rscript myscript.R arg1 arg2 arg3

If your args are strings with spaces in them, enclose within double quotes.

make sure that you have set the image to Image property, but not to the Background

The author of this post (now deleted post) suggests checking your C:\Windows\System32 folder to make sure that the oci.dll exists there. Copying in the file from the Oracle home directory solved this problem for me.

I have just tested this and works fine.

string test = "Testing 1-2-3";

// convert string to stream
byte[] byteArray = Encoding.ASCII.GetBytes(test);
MemoryStream stream = new MemoryStream(byteArray);

// convert stream to string
StreamReader reader = new StreamReader(stream);
string text = reader.ReadToEnd();

If stream has already been written to, you might want to seek to the beginning before first before reading out the text: stream.Seek(0, SeekOrigin.Begin);

Use the value child element instead of the value attribute and specify the Enum class name:

<property name="residence">
    <value type="SocialSecurity$Residence">ALIEN</value>
</property>

The advantage of this approach over just writing value="ALIEN" is that it also works if Spring can't infer the actual type of the enum from the property (e.g. the property's declared type is an interface)._{Adapted from araqnid's comment.}

You can use the CSS Toggle Switch library. Just include the CSS and program the JS yourself: http://ghinda.net/css-toggle-switch/bootstrap.html

Because of this, I'm creating a new object of CaseInsensitiveString for every event. So, it might hit performance.

Creating wrappers or converting key to lower case before lookup both create new objects. Writing your own java.util.Map implementation is the only way to avoid this. It's not too hard, and IMO is worth it. I found the following hash function to work pretty well, up to few hundred keys.

static int ciHashCode(String string)
{
    // length and the low 5 bits of hashCode() are case insensitive
    return (string.hashCode() & 0x1f)*33 + string.length();
}

based on rogerdpack's and Ed999's responses, I've created my .sh version

#!/bin/bash

[ -e list.txt ] && rm list.txt
for f in *.mp4
do
   echo "file $f" >> list.txt
done

ffmpeg -f concat -i list.txt -c copy joined-out.mp4 && rm list.txt

it joins all the *.mp4 files in current folder into joined-out.mp4

tested on mac.

resulting filesize is exact sum of my 60 tested files. Should not be any loss. Just what I needed

Thanks for the input guys, I was able to find the fix, I added and defined the json on top of the app.component.ts file:

var json = require('./[yourFileNameHere].json');

This ultimately produced the markers and is a simple line of code.

As other folks have mentioned, Java, ActiveX, Silverlight, Browser Helper Objects (BHOs) and other plugins are not supported in Microsoft Edge. Most modern browsers are moving away from plugins and toward standard HTML5 controls and technologies.

If you must continue to use the Java plugin in a corporate web app, consider adding the site to an Enterprise Mode site list. This will automatically prompt the user to open in IE.

Sometimes the file is kept in tracking history, try the following steps:

1. git commit, If you are seeing create mode with the big file listed, then do:

2. git filter-branch --index-filter 'git rm -r --cached --ignore-unmatch filename' HEAD. You should see a bunch of Rewrites shown in your console which ends with:

   rm 'filename' and

   the last line Ref was rewritten.

It's done.

Return false from the anonymous function:

$(xml).find("strengths").each(function() {
  // Code
  // To escape from this block based on a condition:
  if (something) return false;
});

From the documentation of the each method:

Returning 'false' from within the each function completely stops the loop through all of the elements (this is like using a 'break' with a normal loop). Returning 'true' from within the loop skips to the next iteration (this is like using a 'continue' with a normal loop).

Dictionaries are specifically designed to do super fast key lookups. They are implemented as hashtables and the more entries the faster they are relative to other methods. Using the exception engine is only supposed to be done when your method has failed to do what you designed it to do because it is a large set of object that give you a lot of functionality for handling errors. I built an entire library class once with everything surrounded by try catch blocks once and was appalled to see the debug output which contained a seperate line for every single one of over 600 exceptions!

I recommend GPick:

sudo apt-get install gpick

Applications -> Graphics -> GPick

It has many more features than gcolor2 but is still extremely simple to use: click on one of the hex swatches, move your mouse around the screen over the colours you want to pick, then press the Space bar to add to your swatch list.

If that doesn't work, another way is to click-and-drag from the centre of the hexagon and release your mouse over the pixel that you want to sample. Then immediately hit Space to copy that color into the next swatch in rotation.

It also has a traditional colour picker (like gcolor2) in the bottom right-hand corner of the window to allow you to pick individual colours with magnification.

tolist() works fine even if encountered a nested array, say a pandas DataFrame;

my_list = [0,1,2,3,4,5,4,3,2,1,0]
my_dt = pd.DataFrame(my_list)
new_list = [i[0] for i in my_dt.values.tolist()]

print(type(my_list),type(my_dt),type(new_list))

I use withRouter to get the location prop. When the component is updated because of a new route, I check if the value changed:

@withRouter
class App extends React.Component {

  static propTypes = {
    location: React.PropTypes.object.isRequired
  }

  // ...

  componentDidUpdate(prevProps) {
    if (this.props.location !== prevProps.location) {
      this.onRouteChanged();
    }
  }

  onRouteChanged() {
    console.log("ROUTE CHANGED");
  }

  // ...
  render(){
    return <Switch>
        <Route path="/" exact component={HomePage} />
        <Route path="/checkout" component={CheckoutPage} />
        <Route path="/success" component={SuccessPage} />
        // ...
        <Route component={NotFound} />
      </Switch>
  }
}

Hope it helps

An easier way is to use the heredoc syntax of PHP. An example:

<?php

echo <<<EOF
<script type="text/javascript">
    document.write("Hello World!");
</script>
EOF;

?>

At its simplest, the difference is one of plurality:

• Backout backs out of a single changelist (whether the most recent or not). i.e. it undoes a single changelist.
• Rollback rolls back changes as much as it needs to in order to get to a previous changelist. i.e. it undoes multiple changelists.

I used to forget which one is which and end up having to look it up many times. To fix this problem, imagine rolling back as several rotations then hopefully the fact that rollback is plural will help you (and me!) remember which one is which. Backout sounds 'less plural' than rollback to me. Imagine backing out of a single parking space.

So, the mnemonic is:

• Rollback → multiple rotations
• Backout → back out of a single car parking space

I hope this helps!

This is a classic example of composition vs inheritance.

In this specific case:

Is the team a list of players with added behavior

or

Is the team an object of its own that happens to contain a list of players.

By extending List you are limiting yourself in a number of ways:

1. You cannot restrict access (for example, stopping people changing the roster). You get all the List methods whether you need/want them all or not.

2. What happens if you want to have lists of other things as well. For example, teams have coaches, managers, fans, equipment, etc. Some of those might well be lists in their own right.

3. You limit your options for inheritance. For example you might want to create a generic Team object, and then have BaseballTeam, FootballTeam, etc. that inherit from that. To inherit from List you need to do the inheritance from Team, but that then means that all the various types of team are forced to have the same implementation of that roster.

Composition - including an object giving the behavior you want inside your object.

Inheritance - your object becomes an instance of the object that has the behavior you want.

Both have their uses, but this is a clear case where composition is preferable.

With a small change, it worked fine for me

I recently installed the latest Django 3.1 and Django Rest Framework 3.11.1 libraries only to eventually realize Django 3.1 is not supported by DRF as of 11 April 2020. I did not realize that the exact releases mentioned need to be used.

If you're pulling your hair out because you can't understand why DRF is not importing check these requirements and make sure your app is compatible.

This is quite easily achievable.

1. We need to allow any unlisted programs to start from RDP.
   1.1 Save the script below on your desktop, the extension must end with .reg.
   

Windows Registry Editor Version 5.00

    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Terminal Server\TSAppAllowList]
    "fDisabledAllowList"=dword:00000001

       1.2 Right click on the file and click Merge, Yes, Ok.

2. Modifying our .rdp file.
   2.1 At the end of our file, add the following code:
   

remoteapplicationmode:i:1
remoteapplicationname:s:This will be the optional description of the app
remoteapplicationprogram:s:Relative or absolute path to the app
                           (Example: taskmgr or C:\Windows\system32\taskmgr.exe)
remoteapplicationcmdline:s:Here you'd put any optional application parameters

remoteapplicationmode:i:1
remoteapplicationname:s:
remoteapplicationprogram:s:mspaint
remoteapplicationcmdline:s:

        2.2 Enter your username and password and connect.

    3. Now you can use your RemoteApp without any issues as if it was running on your local machine

2018 and later solution:

Using viewport-relative units should make your life way easier, given we have the image of a cat:

Now we want this cat inside our code, while respecting aspect ratios:

img {_x000D_
  width: 100%;_x000D_
  height: auto;_x000D_
}

<img src="https://www.petmd.com/sites/default/files/petmd-cat-happy-10.jpg" alt="cat">

So far not really interesting, but what if we would like to change the cats width to be the maximum of 50% of the viewport?

img {_x000D_
  width: 100%;_x000D_
  height: auto;_x000D_
  /* Magic! */_x000D_
  max-width: 50vw;_x000D_
}

<img src="https://www.petmd.com/sites/default/files/petmd-cat-happy-10.jpg" alt="cat">

The same image, but now restricted to a maximum width of 50vw vw (=viewport width) means the image will be X width of the viewport, depending on the digit provided. This also works for height:

img {_x000D_
  width: auto;_x000D_
  height: 100%;_x000D_
  max-height: 20vh;_x000D_
}

<img src="https://www.petmd.com/sites/default/files/petmd-cat-happy-10.jpg" alt="cat">

This restricts the height of the image to a maximum of 20% of the viewport.

All markers in Google Android Maps Api v2 are clickable. You don't need to set any additional properties to your marker. What you need to do - is to register marker click callback to your googleMap and handle click within callback:

public class MarkerDemoActivity extends android.support.v4.app.FragmentActivity
    implements OnMarkerClickListener
{
    private Marker myMarker;    

    private void setUpMap()
    {
        .......
        googleMap.setOnMarkerClickListener(this);

        myMarker = googleMap.addMarker(new MarkerOptions()
                    .position(latLng)
                    .title("My Spot")
                    .snippet("This is my spot!")
                    .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));
        ......
    }

    @Override
    public boolean onMarkerClick(final Marker marker) {

        if (marker.equals(myMarker)) 
        {
            //handle click here
        }
    }
}

here is a good guide on google about marker customization

This command shows the configured heap sizes in bytes.

java -XX:+PrintFlagsFinal -version | grep HeapSize

It works on Amazon AMI on EC2 as well.

What you show looks like a mesh warp. That would be straightforward using OpenGL, but "straightforward OpenGL" is like straightforward rocket science.

I wrote an iOS app for my company called Face Dancerthat's able to do 60 fps mesh warp animations of video from the built-in camera using OpenGL, but it was a lot of work. (It does funhouse mirror type changes to faces - think "fat booth" live, plus lots of other effects.)

Had several modules complain about patch does not apply. One thing I was missing out was that the branches had become stale. After the git merge master generated the patch files using git diff master BRANCH > file.patch. Going to the vanilla branch was able to apply the patch with git apply file.patch

I have not seen many linq solutions here.

I am not sure of the performance implications, however I generally stick to linq as rule of thumb and then optimize later if necessary.

public bool CompareTwoArrays(byte[] array1, byte[] array2)
 {
   return !array1.Where((t, i) => t != array2[i]).Any();
 }

Please do note this only works if they are the same size arrays. an extension could look like so

public bool CompareTwoArrays(byte[] array1, byte[] array2)
 {
   if (array1.Length != array2.Length) return false;
   return !array1.Where((t, i) => t != array2[i]).Any();
 }

It's easier to change the port in VMware Workstation:

1. Edit > Preferences;
2. Shared VMs tab;
3. Disable;
4. Change port;
5. Enable.

Done.

Using MoveToElement you will be able to find or click in whatever point you want, you have just to define the first parameter, it can be the session(winappdriver) or driver(in other ways) which is created when you instance WindowsDriver. Otherwise you can set as first parameter a grid (my case), a list, a panel or whatever you want.

Note: The top-left of your first parameter element will be the position X = 0 and Y = 0

   Actions actions = new Actions(this.session);
    int xPosition = this.session.FindElementsByAccessibilityId("GraphicView")[0].Size.Width - 530;
    int yPosition = this.session.FindElementsByAccessibilityId("GraphicView")[0].Size.Height- 150;
    actions.MoveToElement(this.xecuteClientSession.FindElementsByAccessibilityId("GraphicView")[0], xPosition, yPosition).ContextClick().Build().Perform();

This is happens because Jenkins is not aware about the shell path. In Manage Jenkins -> Configure System -> Shell, set the shell path as

One of the problems of doing automated testing for APIs is that many of the tools require you to have the API server up and running before you run your test suite. It can be a real advantage to have a unit testing framework that is capable of running and querying the APIs in a fully automated test environment.

An option that's good for APIs implemented with Node.JS / Express is to use mocha for automated testing. In addition to unit tests, its easy to write functional tests against the APIs, separated into different test suites. You can start up the API server automatically in the local test environment and set up a local test database. Using make, npm, and a build server, you can create a "make test" target and an incremental build that will run the entire test suite every time a piece of code is submitted to your repository. For the truly fastidious developer, it will even generate a nice HTML code-coverage report showing you which parts of your code base are covered by tests or not. If this sounds interesting, here's a blog post that provides all the technical details.

If you're not using node, then whatever the defacto unit testing framework for the language is (jUnit, cucumber/capybara, etc) - look at its support for spinning up servers in the local test environment and running the HTTP queries. If it's a large project, the effort to get automated API testing and continual integration working will pay off pretty quickly.

Hope that helps.

Got a similar response with https WSDL URL using php soapClient

SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL: Couldn't load from ...

After server has been updated from PHP 5.5.9-1ubuntu4.21 >> PHP 5.5.9-1ubuntu4.23 something went wrong for my client machine osx 10.12.6 / PHP 5.6.30, but MS Web Services Clients connections could be made without issues.

Apache2's server_access.log showed no entry when i tried to load WSDL so i added 'cache_wsdl' => WSDL_CACHE_NONE to prevent client-side wsdl caching, but still got no entries. Finally i tried to load wsdl per CURL -i checked HEADERS but all seemed to be ok..

Only libxml_get_last_error() provided some insight > SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

So I added some ssl options to my call:

$contextOptions = array(
    'ssl' => array(
    'verify_peer' => false,
    'verify_peer_name' => false,
    'allow_self_signed' => true
    ));

$sslContext = stream_context_create($contextOptions);

$params =  array(
    'trace' => 1,
    'exceptions' => true,
    'cache_wsdl' => WSDL_CACHE_NONE,
    'stream_context' => $sslContext
    );

try {
    $proxy = new SoapClient( $wsdl_url, $params );
} catch (SoapFault $proxy) {
    var_dump(libxml_get_last_error());
    var_dump($proxy);
}

In my case 'allow_self_signed' => true did the trick!

Travis Pessetto's answer along with mozey's trunc2 function were the only correct answers, considering how JavaScript represents very small or very large floating point numbers in scientific notation.

For example, parseInt(-2.2043642353916286e-15) will not correctly parse that input. Instead of returning 0 it will return -2.

This is the correct (and imho the least insane) way to do it:

function truncate(number)
{
    return number > 0
         ? Math.floor(number)
         : Math.ceil(number);
}

If your text is in a Bash variable, then Parameter Substitution ${var//\\//} can replace substrings:

$ p='C:\foo\bar.xml'
$ printf '%s\n' "$p"
C:\foo\bar.xml
$ printf '%s\n' "${p//\\//}"
C:/foo/bar.xml

This may be leaner and clearer that filtering through a command such as tr or sed.

I know this question is too old to be about Java 8, but for those using Java 8 you can easily use removeIf():

Collection<Integer> l = new ArrayList<Integer>();

for (int i=0; i < 10; ++i) {
    l.add(new Integer(4));
    l.add(new Integer(5));
    l.add(new Integer(6));
}

l.removeIf(i -> i.intValue() == 5);

You need to float all the buttons to left and make sure its width to fit within outer container.

CSS:

.btn{

   float:left;
}

HTML:

    <button type="submit" class="btn" onClick="return false;" >Save</button>
    <button type="submit" class="btn" onClick="return false;">Publish</button>
    <button class="btn">Back</button>

I've run into this issue often enough that I finally created my own barebones GUI for testing websockets. It's called Socket Wrench, it supports

• multiple concurrent connections to servers (with all responses and connections displayed in the same view),
• comprehensive message history to enable easy re-use of messages, and
• custom headers for the initial connection request.

It's available for Mac OS X, Windows and Linux and you can get it from here.

Yes, it’s frustrating—sometimes type and other programs print gibberish, and sometimes they do not.

First of all, Unicode characters will only display if the current console font contains the characters. So use a TrueType font like Lucida Console instead of the default Raster Font.

But if the console font doesn’t contain the character you’re trying to display, you’ll see question marks instead of gibberish. When you get gibberish, there’s more going on than just font settings.

When programs use standard C-library I/O functions like printf, the program’s output encoding must match the console’s output encoding, or you will get gibberish. chcp shows and sets the current codepage. All output using standard C-library I/O functions is treated as if it is in the codepage displayed by chcp.

Matching the program’s output encoding with the console’s output encoding can be accomplished in two different ways:

• A program can get the console’s current codepage using chcp or GetConsoleOutputCP, and configure itself to output in that encoding, or

• You or a program can set the console’s current codepage using chcp or SetConsoleOutputCP to match the default output encoding of the program.

However, programs that use Win32 APIs can write UTF-16LE strings directly to the console with WriteConsoleW. This is the only way to get correct output without setting codepages. And even when using that function, if a string is not in the UTF-16LE encoding to begin with, a Win32 program must pass the correct codepage to MultiByteToWideChar. Also, WriteConsoleW will not work if the program’s output is redirected; more fiddling is needed in that case.

type works some of the time because it checks the start of each file for a UTF-16LE Byte Order Mark (BOM), i.e. the bytes 0xFF 0xFE. If it finds such a mark, it displays the Unicode characters in the file using WriteConsoleW regardless of the current codepage. But when typeing any file without a UTF-16LE BOM, or for using non-ASCII characters with any command that doesn’t call WriteConsoleW—you will need to set the console codepage and program output encoding to match each other.

How can we find this out?

Here’s a test file containing Unicode characters:

ASCII     abcde xyz
German    äöü ÄÖÜ ß
Polish    aezznl
Russian   ??????? ???
CJK       ??

Here’s a Java program to print out the test file in a bunch of different Unicode encodings. It could be in any programming language; it only prints ASCII characters or encoded bytes to stdout.

import java.io.*;

public class Foo {

    private static final String BOM = "\ufeff";
    private static final String TEST_STRING
        = "ASCII     abcde xyz\n"
        + "German    äöü ÄÖÜ ß\n"
        + "Polish    aezznl\n"
        + "Russian   ??????? ???\n"
        + "CJK       ??\n";

    public static void main(String[] args)
        throws Exception
    {
        String[] encodings = new String[] {
            "UTF-8", "UTF-16LE", "UTF-16BE", "UTF-32LE", "UTF-32BE" };

        for (String encoding: encodings) {
            System.out.println("== " + encoding);

            for (boolean writeBom: new Boolean[] {false, true}) {
                System.out.println(writeBom ? "= bom" : "= no bom");

                String output = (writeBom ? BOM : "") + TEST_STRING;
                byte[] bytes = output.getBytes(encoding);
                System.out.write(bytes);
                FileOutputStream out = new FileOutputStream("uc-test-"
                    + encoding + (writeBom ? "-bom.txt" : "-nobom.txt"));
                out.write(bytes);
                out.close();
            }
        }
    }
}

The output in the default codepage? Total garbage!

The only thing that works is UTF-16LE file, with a BOM, printed to the console via type.

If we use anything other than type to print the file, we get garbage:

Z:\andrew\projects\sx\1259084>copy uc-test-UTF-16LE-bom.txt CON
 ¦A S C I I           a b c d e   x y z
 G e r m a n         õ ÷ ³   - Í _   ¯
 P o l i s h         ????z?|?D?B?

 C J K               `O}Y
         1 file(s) copied.

From the fact that copy CON does not display Unicode correctly, we can conclude that the type command has logic to detect a UTF-16LE BOM at the start of the file, and use special Windows APIs to print it.

We can see this by opening cmd.exe in a debugger when it goes to type out a file:

After type opens a file, it checks for a BOM of 0xFEFF—i.e., the bytes 0xFF 0xFE in little-endian—and if there is such a BOM, type sets an internal fOutputUnicode flag. This flag is checked later to decide whether to call WriteConsoleW.

But that’s the only way to get type to output Unicode, and only for files that have BOMs and are in UTF-16LE. For all other files, and for programs that don’t have special code to handle console output, your files will be interpreted according to the current codepage, and will likely show up as gibberish.

You can emulate how type outputs Unicode to the console in your own programs like so:

#include <stdio.h>
#define UNICODE
#include <windows.h>

static LPCSTR lpcsTest =
    "ASCII     abcde xyz\n"
    "German    äöü ÄÖÜ ß\n"
    "Polish    aezznl\n"
    "Russian   ??????? ???\n"
    "CJK       ??\n";

int main() {
    int n;
    wchar_t buf[1024];

    HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);

    n = MultiByteToWideChar(CP_UTF8, 0,
            lpcsTest, strlen(lpcsTest),
            buf, sizeof(buf));

    WriteConsole(hConsole, buf, n, &n, NULL);

    return 0;
}

This program works for printing Unicode on the Windows console using the default codepage.

For the sample Java program, we can get a little bit of correct output by setting the codepage manually, though the output gets messed up in weird ways:

Z:\andrew\projects\sx\1259084>chcp 65001
Active code page: 65001

Z:\andrew\projects\sx\1259084>java Foo

A S C I I           a b c d e   x y z
…

However, a C program that sets a Unicode UTF-8 codepage:

#include <stdio.h>
#include <windows.h>

int main() {
    int c, n;
    UINT oldCodePage;
    char buf[1024];

    oldCodePage = GetConsoleOutputCP();
    if (!SetConsoleOutputCP(65001)) {
        printf("error\n");
    }

    freopen("uc-test-UTF-8-nobom.txt", "rb", stdin);
    n = fread(buf, sizeof(buf[0]), sizeof(buf), stdin);
    fwrite(buf, sizeof(buf[0]), n, stdout);

    SetConsoleOutputCP(oldCodePage);

    return 0;
}

does have correct output:

Z:\andrew\projects\sx\1259084>.\test
ASCII     abcde xyz
German    äöü ÄÖÜ ß
Polish    aezznl
Russian   ??????? ???
CJK       ??

The moral of the story?

• type can print UTF-16LE files with a BOM regardless of your current codepage
• Win32 programs can be programmed to output Unicode to the console, using WriteConsoleW.
• Other programs which set the codepage and adjust their output encoding accordingly can print Unicode on the console regardless of what the codepage was when the program started
• For everything else you will have to mess around with chcp, and will probably still get weird output.

There is also the possibility of using blocks:

NSOperationQueue *mainQueue = [NSOperationQueue mainQueue];
[[NSNotificationCenter defaultCenter] 
     addObserverForName:@"notificationName" 
     object:nil
     queue:mainQueue
     usingBlock:^(NSNotification *notification)
     {
          NSLog(@"Notification received!");
          NSDictionary *userInfo = notification.userInfo;

          // ...
     }];

Look at your message

So first thing it relate to permission

you have to check file permission change mode this /var/lib/php/session/

Second thing it relate to session.save_path

Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/var/lib/php/session) in Unknown on line 0

in php.ini

[Session]
; Handler used to store/retrieve data.
session.save_handler = files

; Argument passed to save_handler. In the case of files, this is the path
; where data files are stored. Note: Windows users have to change this
; variable in order to use PHP's session functions.
; 
; As of PHP 4.0.1, you can define the path as:
; 
;     session.save_path = "N;/path"
; 
; where N is an integer. Instead of storing all the session files in
; /path, what this will do is use subdirectories N-levels deep, and
; store the session data in those directories. This is useful if you
; or your OS have problems with lots of files in one directory, and is
; a more efficient layout for servers that handle lots of sessions.
; 
; NOTE 1: PHP will not create this directory structure automatically.
;         You can use the script in the ext/session dir for that purpose.

You are not allowed to have a CNAME record for the domain, as the CNAME is an aliasing feature that covers all data types (regardless of whether the client looks for MX, NS or SOA records). CNAMEs also always refer to a new name, not an ip-address, so there are actually two errors in the single line

@                        IN CNAME   88.198.38.XXX

Changing that CNAME to an A record should make it work, provided the ip-address you use is the correct one for your Heroku app.

The only correct way in DNS to make a simple domain.com name work in the browser, is to point the domain to an IP-adress with an A record.

'SET' is forgotten

ALTER TABLE ONLY users ALTER COLUMN lang SET DEFAULT 'en_GB';

Go with STL. There's no performance penalty. The algorithms are very efficient and they do a good job of handling the kinds of details that most of us would not think about.

For a simple way, use system():

#include <stdlib.h>
...
int status = system("./foo 1 2 3");

system() will wait for foo to complete execution, then return a status variable which you can use to check e.g. exitcode (the command's exitcode gets multiplied by 256, so divide system()'s return value by that to get the actual exitcode: int exitcode = status / 256).

The manpage for wait() (in section 2, man 2 wait on your Linux system) lists the various macros you can use to examine the status, the most interesting ones would be WIFEXITED and WEXITSTATUS.

Alternatively, if you need to read foo's standard output, use popen(3), which returns a file pointer (FILE *); interacting with the command's standard input/output is then the same as reading from or writing to a file.

What is this? :)

background-color: #D8F0DA;

Try

 background: none

And override works only if property is exactly the same.

background doesn't override background-color.

If you want alpha transparency, then use something like this

background: rgba(100, 100, 100, 0.5);

You could try the Mersenne Twister algorithm.

It has a good blend of speed and randomness, and a GPL implementation.

If you want a one-liner from numpy and aren't too concerned about performance, try:

np.sum(np.diag(the_array,1),0)[:-1]

Explanation: np.diag(the_array,1) creates a matrix with your array one-off the diagonal, np.sum(...,0) sums the matrix column-wise, and ...[:-1] takes the elements that would correspond to the size of the original array. Playing around with the 1 and :-1 as parameters can give you shifts in different directions.

If you want to just undo the previous commit's changes to that one file, you can try this:

git checkout branchname^ filename

This will checkout the file as it was before the last commit. If you want to go a few more commits back, use the branchname~n notation.

As brb tea says, depends on the database implementation and the algorithm they use: MVCC or Two Phase Locking.

CUBRID (open source RDBMS) explains the idea of this two algorithms:

• Two-phase locking (2PL)

The first one is when the T2 transaction tries to change the A record, it knows that the T1 transaction has already changed the A record and waits until the T1 transaction is completed because the T2 transaction cannot know whether the T1 transaction will be committed or rolled back. This method is called Two-phase locking (2PL).

• Multi-version concurrency control (MVCC)

The other one is to allow each of them, T1 and T2 transactions, to have their own changed versions. Even when the T1 transaction has changed the A record from 1 to 2, the T1 transaction leaves the original value 1 as it is and writes that the T1 transaction version of the A record is 2. Then, the following T2 transaction changes the A record from 1 to 3, not from 2 to 4, and writes that the T2 transaction version of the A record is 3.

When the T1 transaction is rolled back, it does not matter if the 2, the T1 transaction version, is not applied to the A record. After that, if the T2 transaction is committed, the 3, the T2 transaction version, will be applied to the A record. If the T1 transaction is committed prior to the T2 transaction, the A record is changed to 2, and then to 3 at the time of committing the T2 transaction. The final database status is identical to the status of executing each transaction independently, without any impact on other transactions. Therefore, it satisfies the ACID property. This method is called Multi-version concurrency control (MVCC).

The MVCC allows concurrent modifications at the cost of increased overhead in memory (because it has to maintain different versions of the same data) and computation (in REPETEABLE_READ level you can't loose updates so it must check the versions of the data, like Hiberate does with Optimistick Locking).

In 2PL Transaction isolation levels control the following:

• Whether locks are taken when data is read, and what type of locks are requested.

• How long the read locks are held.

• Whether a read operation referencing rows modified by another transaction:

  • Block until the exclusive lock on the row is freed.

  • Retrieve the committed version of the row that existed at the time the statement or transaction started.

  • Read the uncommitted data modification.

Choosing a transaction isolation level does not affect the locks that are acquired to protect data modifications. A transaction always gets an exclusive lock on any data it modifies and holds that lock until the transaction completes, regardless of the isolation level set for that transaction. For read operations, transaction isolation levels primarily define the level of protection from the effects of modifications made by other transactions.

A lower isolation level increases the ability of many users to access data at the same time, but increases the number of concurrency effects, such as dirty reads or lost updates, that users might encounter.

Concrete examples of the relation between locks and isolation levels in SQL Server (use 2PL except on READ_COMMITED with READ_COMMITTED_SNAPSHOT=ON)

• READ_UNCOMMITED: do not issue shared locks to prevent other transactions from modifying data read by the current transaction. READ UNCOMMITTED transactions are also not blocked by exclusive locks that would prevent the current transaction from reading rows that have been modified but not committed by other transactions. [...]

• READ_COMMITED:

  • If READ_COMMITTED_SNAPSHOT is set to OFF (the default): uses shared locks to prevent other transactions from modifying rows while the current transaction is running a read operation. The shared locks also block the statement from reading rows modified by other transactions until the other transaction is completed. [...] Row locks are released before the next row is processed. [...]
  • If READ_COMMITTED_SNAPSHOT is set to ON, the Database Engine uses row versioning to present each statement with a transactionally consistent snapshot of the data as it existed at the start of the statement. Locks are not used to protect the data from updates by other transactions.

• REPETEABLE_READ: Shared locks are placed on all data read by each statement in the transaction and are held until the transaction completes.

• SERIALIZABLE: Range locks are placed in the range of key values that match the search conditions of each statement executed in a transaction. [...] The range locks are held until the transaction completes.

To exit you application you can use the following:

getActivity().finish();
Process.killProcess(Process.myPid());
System.exit(1);

Also to stop the services too call the following method:

private void stopServices() {        
    final ActivityManager activityManager = SystemServices.getActivityManager(context);
    final List<ActivityManager.RunningServiceInfo> runningServices = activityManager.getRunningServices(Integer.MAX_VALUE);
    final int pid = Process.myPid();
    for (ActivityManager.RunningServiceInfo serviceInfo : runningServices) {
        if (serviceInfo.pid == pid && !SenderService.class.getName().equals(serviceInfo.service.getClassName())) {
            try {
                final Intent intent = new Intent();
                intent.setComponent(serviceInfo.service);

PEAR: Mail worked for me sending email messages from Gmail. Also, the instructions: How to Send Email from a PHP Script Using SMTP Authentication (Using PEAR::Mail) helped greatly. Thanks, CMS!

I found slightly different problem running R on through mac terminal, but connecting remotely to an Ubuntu server, which prevented me from successfully installing a library.

The solution I have was finding out what "LANG" variable is used in Ubuntu terminal

Ubuntu > echo $LANG
en_US.TUF-8

I got "en_US.TUF-8" reply from Ubuntu.

In R session, however, I got "UTF-8" as the default value and it complained that LC_TYPEC Setting LC_CTYPE failed, using "C"

R> Sys.getenv("LANG")
"UTF-8"

So, I tried to change this variable in R. It worked.

R> Sys.setenv(LANG="en_US.UTF-8")

Yes -- parseFloat.

parseFloat(document.getElementById(amtid4).innerHTML);

For formatting numbers, use toFixed:

var num = parseFloat(document.getElementById(amtid4).innerHTML).toFixed(2);

num is now a string with the number formatted with two decimal places.

You can get the current path:

string AssemblyPath = Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location).ToString();

Good luck!

Use JSON classes for parsing e.g

JSONObject mainObject = new JSONObject(Your_Sring_data);
JSONObject uniObject = mainObject.getJSONObject("university");
String  uniName = uniObject.getString("name");
String uniURL = uniObject.getString("url");

JSONObject oneObject = mainObject.getJSONObject("1");
String id = oneObject.getString("id");
....

Since React eventually boils down to plain old JavaScript, you can really place it anywhere! For instance, you could place it on a componentDidMount() in a React class.

For you edit, you may want to try something like this:

class Component extends React.Component {
  constructor(props) {
    super(props);
    this.onAddBucket = this.onAddBucket.bind(this);
  }
  componentWillMount() {
    this.setState({
      buckets: {},
    })
  }
  componentDidMount() {
    this.onAddBucket();
  }
  onAddBucket() {
    let self = this;
    let getToken = localStorage.getItem('myToken');
    var apiBaseUrl = "...";
    let input = {
      "name" :  this.state.fields["bucket_name"]
    }
    axios.defaults.headers.common['Authorization'] = getToken;
    axios.post(apiBaseUrl+'...',input)
    .then(function (response) {
      if (response.data.status == 200) {
        this.setState({
          buckets: this.state.buckets.concat(response.data.buckets),
        });
      } else {
        alert(response.data.message);
      }
    })
    .catch(function (error) {
      console.log(error);
    });
  }
  render() {
    return (
      {this.state.bucket}
    );
  }
}

I'm not sure about g++, but if you're using GNU Make then "make -j N" (where N is the number of threads make can create) will allow make to run multple g++ jobs at the same time (so long as the files do not depend on each other).

In you app config file change the url to localhost/example/public

Then when you want to link to something

<a href="{{ url('page') }}">Some Text</a>

without blade

<a href="<?php echo url('page') ?>">Some Text</a>

I faced the same problem and solved this like i described below: As You have downloaded and installed dnspython successfully so

1. Enter into folder dnspython
2. You will find dns directory, now copy it
3. Then paste it to inside site-packages directory

That's all. Now your problem will go

If dnspython isn't installed you can install it this way :

1. go to your python installation folder site-packages directory
2. open cmd here and enter the command : pip install dnspython

Now, dnspython will be installed successfully.

Easier way is also to do this.

let elementReference = document.querySelector('<your css, #id selector>');
    if (elementReference instanceof HTMLElement) {
        elementReference.focus();
    }

Check this code based on the article Geo-Distance-Search-with-MySQL:

Example: find the 10 nearest hotels to my current location in a 10 miles radius:

#Please notice that (lat,lng) values mustn't be negatives to perform all calculations

set @my_lat=34.6087674878572; 
set @my_lng=58.3783670308302;
set @dist=10; #10 miles radius

SELECT dest.id, dest.lat, dest.lng,  3956 * 2 * ASIN(SQRT(POWER(SIN((@my_lat -abs(dest.lat)) * pi()/180 / 2),2) + COS(@my_lat * pi()/180 ) * COS(abs(dest.lat) *  pi()/180) * POWER(SIN((@my_lng - abs(dest.lng)) *  pi()/180 / 2), 2))
) as distance
FROM hotel as dest
having distance < @dist
ORDER BY distance limit 10;

#Also notice that distance are expressed in terms of radius.

You can also use dplyr's distinct() function! It tends to be more efficient than alternative options, especially if you have loads of observations.

distinct_data <- dplyr::distinct(yourdata)

From Sql Server 2008 you have "date" format.

So you can use

SELECT * FROM LOGS WHERE CONVERT(date,[CHECK_IN]) BETWEEN '2013-10-18' AND '2013-10-18'

https://docs.microsoft.com/en-us/sql/t-sql/data-types/date-transact-sql

It cant find the entry point for your program, in this case main(). Your linker settings are likely incorrect.

See this post here

If all you want is some very basic error checking, you could just check the length of the string.

              string guidStr = "";
              if( guidStr.Length == Guid.Empty.ToString().Length )
                 Guid g = new Guid( guidStr );

I fixed my error. just removed "Value" from this line:

If drv.Item("Quantity").Value < 5  Then

So it will look like

If drv.Item("Quantity") < 5 Then

exit is a helper for the interactive shell - sys.exit is intended for use in programs.

The site module (which is imported automatically during startup, except if the -S command-line option is given) adds several constants to the built-in namespace (e.g. exit). They are useful for the interactive interpreter shell and should not be used in programs.

Technically, they do mostly the same: raising SystemExit. sys.exit does so in sysmodule.c:

static PyObject *
sys_exit(PyObject *self, PyObject *args)
{
    PyObject *exit_code = 0;
    if (!PyArg_UnpackTuple(args, "exit", 0, 1, &exit_code))
        return NULL;
    /* Raise SystemExit so callers may catch it or clean up. */
    PyErr_SetObject(PyExc_SystemExit, exit_code);
   return NULL;
}

While exit is defined in site.py and _sitebuiltins.py, respectively.

class Quitter(object):
    def __init__(self, name):
        self.name = name
    def __repr__(self):
        return 'Use %s() or %s to exit' % (self.name, eof)
    def __call__(self, code=None):
        # Shells like IDLE catch the SystemExit, but listen when their
        # stdin wrapper is closed.
        try:
            sys.stdin.close()
        except:
            pass
        raise SystemExit(code)
__builtin__.quit = Quitter('quit')
__builtin__.exit = Quitter('exit')

Note that there is a third exit option, namely os._exit, which exits without calling cleanup handlers, flushing stdio buffers, etc. (and which should normally only be used in the child process after a fork()).

I found the GeoCoder javascript a little buggy when I included it in my jsp files.

You can also try this:

    var lat = "43.7667855" ;
    var long = "-79.2157321" ;
    var url = "https://maps.googleapis.com/maps/api/geocode/json?latlng="
       +lat+","+long+"&sensor=false";
    $.get(url).success(function(data) {
       var loc1 = data.results[0];
       var county, city;
         $.each(loc1, function(k1,v1) {
            if (k1 == "address_components") {
               for (var i = 0; i < v1.length; i++) {
                  for (k2 in v1[i]) {
                     if (k2 == "types") {
                        var types = v1[i][k2];
                        if (types[0] =="sublocality_level_1") {
                            county = v1[i].long_name;
                            //alert ("county: " + county);
                        } 
                        if (types[0] =="locality") {
                           city = v1[i].long_name;
                           //alert ("city: " + city);
                       } 
                     }

                  }          

               }

            }

         });
         $('#city').html(city); 
    }); 

When your browser redirects the user to Google's oAuth page, are you passing as a parameter the redirect URI you want Google's server to return to with the token response? Setting a redirect URI in the console is not a way of telling Google where to go when a login attempt comes in, but rather it's a way of telling Google what the allowed redirect URIs are (so if someone else writes a web app with your client ID but a different redirect URI it will be disallowed); your web app should, when someone clicks the "login" button, send the browser to:

https://accounts.google.com/o/oauth2/auth?client_id=XXXXX&redirect_uri=http://localhost:8080/WEBAPP/youtube-callback.html&response_type=code&scope=https://www.googleapis.com/auth/youtube.upload

(the callback URI passed as a parameter must be url-encoded, btw).

When Google's server gets authorization from the user, then, it'll redirect the browser to whatever you sent in as the redirect_uri. It'll include in that request the token as a parameter, so your callback page can then validate the token, get an access token, and move on to the other parts of your app.

If you visit:

http://code.google.com/p/google-api-java-client/wiki/OAuth2#Authorization_Code_Flow

You can see better samples of the java client there, demonstrating that you have to override the getRedirectUri method to specify your callback path so the default isn't used.

The redirect URIs are in the client_secrets.json file for multiple reasons ... one big one is so that the oAuth flow can verify that the redirect your app specifies matches what your app allows.

If you visit https://developers.google.com/api-client-library/java/apis/youtube/v3 You can generate a sample application for yourself that's based directly off your app in the console, in which (again) the getRedirectUri method is overwritten to use your specific callbacks.

I'm posting my solution for the other sleep-deprived souls out there:

If you're using RVM, double-check that you're in the correct folder, using the correct ruby version and gemset. I had an array of terminal tabs open, and one of them was in a different directory. typing "rails console" produced the error because my default rails distro is 2.3.x.

I noticed the error on my part, cd'd to the correct directory, and my .rvmrc file did the rest.

RVM is not like Git. In git, changing branches in one shell changes it everywhere. It's literally rewriting the files in question. RVM, on the other hand, is just setting shell variables, and must be set for each new shell you open.

In case you're not familiar with .rvmrc, you can put a file with that name in any directory, and rvm will pick it up and use the version/gemset specified therein, whenever you change to that directory. Here's a sample .rvmrc file:

rvm use 1.9.2@turtles

This will switch to the latest version of ruby 1.9.2 in your RVM collection, using the gemset "turtles". Now you can open up a hundred tabs in Terminal (as I end up doing) and never worry about the ruby version it's pointing to.

You can use

document.getElementById("parentID").appendChild(/*..your content created using DOM methods..*/)

or

document.getElementById("parentID").innerHTML+= "new content"

One way would be with sed. For example:

echo $name | sed -e 's?http://www\.??'

Normally the sed regular expressions are delimited by `/', but you can use '?' since you're searching for '/'. Here's another bash trick. @DigitalTrauma's answer reminded me that I ought to suggest it. It's similar:

echo ${name#http://www.}

(DigitalTrauma also gets credit for reminding me that the "http://" needs to be handled.)

The maven dependency plugin saved me a lot of time fondling with ant tasks:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-dependency-plugin</artifactId>
    <executions>
        <execution>
            <id>install-jar</id>
            <phase>install</phase>
            <goals>
                <goal>copy</goal>
            </goals>
            <configuration>
                <artifactItems>
                    <artifactItem>
                        <groupId>...</groupId>
                        <artifactId>...</artifactId>
                        <version>...</version>
                    </artifactItem>
                </artifactItems>
                <outputDirectory>...</outputDirectory>
                <stripVersion>true</stripVersion>
            </configuration>
        </execution>
    </executions>
</plugin>

The dependency:copy is documentend, and has more useful goals like unpack.

In express 4.0 they got it right :)

res.sendStatus(statusCode)
// Sets the response HTTP status code to statusCode and send its string representation as the response body.

res.sendStatus(200); // equivalent to res.status(200).send('OK')
res.sendStatus(403); // equivalent to res.status(403).send('Forbidden')
res.sendStatus(404); // equivalent to res.status(404).send('Not Found')
res.sendStatus(500); // equivalent to res.status(500).send('Internal Server Error')

//If an unsupported status code is specified, the HTTP status is still set to statusCode and the string version of the code is sent as the response body.

res.sendStatus(2000); // equivalent to res.status(2000).send('2000')

There is probably a better way to do this, but it gets the job done:

var ms = 298999;
var min = ms / 1000 / 60;
var r = min % 1;
var sec = Math.floor(r * 60);
if (sec < 10) {
    sec = '0'+sec;
}
min = Math.floor(min);
console.log(min+':'+sec);

Not sure why you have the << operator in your minutes line, I don't think it's needed just floor the minutes before you display.

Getting the remainder of the minutes with % gives you the percentage of seconds elapsed in that minute, so multiplying it by 60 gives you the amount of seconds and flooring it makes it more fit for display although you could also get sub-second precision if you want.

If seconds are less than 10 you want to display them with a leading zero.

You'll first need to separate your numpy array into two separate arrays containing x and y values.

x = [1, 2, 3, 9]
y = [1, 4, 1, 3]

curve_fit also requires a function that provides the type of fit you would like. For instance, a linear fit would use a function like

def func(x, a, b):
    return a*x + b

scipy.optimize.curve_fit(func, x, y) will return a numpy array containing two arrays: the first will contain values for a and b that best fit your data, and the second will be the covariance of the optimal fit parameters.

Here's an example for a linear fit with the data you provided.

import numpy as np
from scipy.optimize import curve_fit

x = np.array([1, 2, 3, 9])
y = np.array([1, 4, 1, 3])

def fit_func(x, a, b):
    return a*x + b

params = curve_fit(fit_func, x, y)

[a, b] = params[0]

This code will return a = 0.135483870968 and b = 1.74193548387

Here's a plot with your points and the linear fit... which is clearly a bad one, but you can change the fitting function to obtain whatever type of fit you would like.

You need formulas to convert latitude and longitude to rectangular coordinates. There are a great number to choose from and each will distort the map in a different way. Wolfram MathWorld has a good collection:
