modern solution for css

html[data-useragent*='MSIE 10.0'] .any {
  your-style: here;
}

I was looking for a good option for IE10 and below CSS styling (but it would work for IE8 only as well) and I came up with this idea:

<!--[if lt IE 10]><div class="column IE10-fix"><![endif]-->
<!--[if !lt IE 10]><!--><div class="column"><!--<![endif]-->

I declare my div or whatever you want with an extra class, this allows me to have extra CSS in the same stylesheet in a very readable manner.

It's W3C valid and not a weird CSS hack.

I get this code works on my browser:

<!--[if lt IE 9]>
  <script src="https://oss.maxcdn.com/libs/html5shiv/3.7.0/html5shiv.js"></script>
  <script src="https://oss.maxcdn.com/libs/respond.js/1.3.0/respond.min.js"></script>
<![endif]-->

Note for this code: HTML5 Shiv and Respond.js IE8 support of HTML5 elements and media queries

I'm pretty sure C-style casting syntax works in Objective C, so try that, too:

int myInt = (int) myFloat;

It might silence a compiler warning, at least.

There are some optimizations you can use when filling a DataTable, such as calling BeginLoadData(), inserting the data, then calling EndLoadData(). This turns off some internal behavior within the DataTable, such as index maintenance, etc. See this article for further details.

Install Command Line Tools Works for me:

xcode-select --install

To use support libraries starting from version 26.0.0 you need to add Google's Maven repository to your project's build.gradle file as described here: https://developer.android.com/topic/libraries/support-library/setup.html

allprojects {
        repositories {
            jcenter()
            maven {
                url "https://maven.google.com"
            }
        }
    }

For Android Studio 3.0.0 and above:

allprojects {
        repositories {
            jcenter()
            google()
        }
    }

packages:

• library(httr)
• library(jsonlite)

I have had issues converting json to dataframe/csv. For my case I did:

Token <- "245432532532"
source <- "http://......."
header_type <- "applcation/json"
full_token <- paste0("Bearer ", Token)
response <- GET(n_source, add_headers(Authorization = full_token, Accept = h_type), timeout(120), verbose())
text_json <- content(response, type = 'text', encoding = "UTF-8")
jfile <- fromJSON(text_json)
df <- as.data.frame(jfile)

then from df to csv.

In this format it should be easy to convert it to multiple .csvs if needed.

The important part is content function should have type = 'text'.

Your submission will cancel the redirect or vice versa.

I do not see the reason for the redirect in the first place since why do you have an order form that does nothing.

That said, here is how to do it. Firstly NEVER put code on the submit button but do it in the onsubmit, secondly return false to stop the submission

NOTE This code will IGNORE the action and ONLY execute the script due to the return false/preventDefault

function redirect() {
  window.location.replace("login.php");
  return false;
}

using

<form name="form1" id="form1" method="post" onsubmit="return redirect()">  
  <input type="submit" class="button4" name="order" id="order" value="Place Order" >
</form>

Or unobtrusively:

window.onload=function() {
  document.getElementById("form1").onsubmit=function() {
    window.location.replace("login.php");
    return false;
  }
}

using

<form id="form1" method="post">  
  <input type="submit" class="button4" value="Place Order" >
</form>

jQuery:

$("#form1").on("submit",function(e) {
   e.preventDefault(); // cancel submission
   window.location.replace("login.php");
});

-----

Example:

$("#form1").on("submit", function(e) {_x000D_
  e.preventDefault(); // cancel submission_x000D_
  alert("this could redirect to login.php"); _x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>_x000D_
_x000D_
_x000D_
<form id="form1" method="post" action="javascript:alert('Action!!!')">_x000D_
  <input type="submit" class="button4" value="Place Order">_x000D_
</form>

With Matplotlib prior to version 1.0.1, show() should only be called once per program, even if it seems to work within certain environments (some backends, on some platforms, etc.).

The relevant drawing function is actually draw():

import matplotlib.pyplot as plt

plt.plot(range(10))  # Creates the plot.  No need to save the current figure.
plt.draw()  # Draws, but does not block
raw_input()  # This shows the first figure "separately" (by waiting for "enter").

plt.figure()  # New window, if needed.  No need to save it, as pyplot uses the concept of current figure
plt.plot(range(10, 20))
plt.draw()
# raw_input()  # If you need to wait here too...

# (...)

# Only at the end of your program:
plt.show()  # blocks

It is important to recognize that show() is an infinite loop, designed to handle events in the various figures (resize, etc.). Note that in principle, the calls to draw() are optional if you call matplotlib.ion() at the beginning of your script (I have seen this fail on some platforms and backends, though).

I don't think that Matplotlib offers a mechanism for creating a figure and optionally displaying it; this means that all figures created with figure() will be displayed. If you only need to sequentially display separate figures (either in the same window or not), you can do like in the above code.

Now, the above solution might be sufficient in simple cases, and for some Matplotlib backends. Some backends are nice enough to let you interact with the first figure even though you have not called show(). But, as far as I understand, they do not have to be nice. The most robust approach would be to launch each figure drawing in a separate thread, with a final show() in each thread. I believe that this is essentially what IPython does.

The above code should be sufficient most of the time.

PS: now, with Matplotlib version 1.0.1+, show() can be called multiple times (with most backends).

My guess is that you are trying to restore in lower versions which wont work

//Get
var bla = $('#txt_name').val();

//Set
$('#txt_name').val(bla);

I prefer option two because it clearly shows the list item as the possessor of that nested list. I would always lean towards semantically sound HTML.

If you have XDocument it is easier to use LINQ-to-XML:

var document = XDocument.Load(fileName);
var name = document.Descendants(XName.Get("Name", @"http://demo.com/2011/demo-schema")).First().Value;

If you are sure that XPath is the only solution you need:

using System.Xml.XPath;

var document = XDocument.Load(fileName);
var namespaceManager = new XmlNamespaceManager(new NameTable());
namespaceManager.AddNamespace("empty", "http://demo.com/2011/demo-schema");
var name = document.XPathSelectElement("/empty:Report/empty:ReportInfo/empty:Name", namespaceManager).Value;

These come from the class version. If you try to load something compiled for java 6 in a java 5 runtime you'll get the error, incompatible class version, got 50, expected 49. Or something like that.

See here in byte offset 7 for more info.

Additional info can also be found here.

OAuth v2 specs indicates:

Access token attributes and the methods used to access protected resources are beyond the scope of this specification and are defined by companion specifications.

My Authorisation Server has a webservice (SOAP) endpoint that allows the Resource Server to know whether the access_token is valid.

Sounds like you're calling sp_executesql with a VARCHAR statement, when it needs to be NVARCHAR.

e.g. This will give the error because @SQL needs to be NVARCHAR

DECLARE @SQL VARCHAR(100)
SET @SQL = 'SELECT TOP 1 * FROM sys.tables'
EXECUTE sp_executesql @SQL

So:

DECLARE @SQL NVARCHAR(100)
SET @SQL = 'SELECT TOP 1 * FROM sys.tables'
EXECUTE sp_executesql @SQL

this is not your answer but is for those come here searching solution for another problem. I wanted to get sum of a column of related table conditionally. In my database Deals has many Activities I wanted to get the sum of the "amount_total" from Activities table where activities.deal_id = deal.id and activities.status = paid so i did this.

$query->withCount([
'activity AS paid_sum' => function ($query) {
            $query->select(DB::raw("SUM(amount_total) as paidsum"))->where('status', 'paid');
        }
    ]);

it returns

"paid_sum_count" => "320.00"

in Deals attribute.

This it now the sum which i wanted to get not the count.

Let's suppose you want to find all int not preceded by unsigned:

With support for negative look-behind:

(?<!unsigned )int

Without support for negative look-behind:

((?!unsigned ).{9}|^.{0,8})int

Basically idea is to grab n preceding characters and exclude match with negative look-ahead, but also match the cases where there's no preceeding n characters. (where n is length of look-behind).

So the regex in question:

(?<!filename)\.js$

would translate to:

((?!filename).{8}|^.{0,7})\.js$

You might need to play with capturing groups to find exact spot of the string that interests you or you want't to replace specific part with something else.

$rootbeer = (float) $InvoicedUnits;

Should do it for you. Check out Type-Juggling. You should also read String conversion to Numbers.

you could use TextChanged/ Keypress event, use a regex to filter on numbers and take some action.

I wrote this awhile back to do just what you're looking for.

Use union as follows:

val sc = new SparkContext(...)
val r1 = sc.textFile("xxx1")
val r2 = sc.textFile("xxx2")
...
val rdds = Seq(r1, r2, ...)
val bigRdd = sc.union(rdds)

Then the bigRdd is the RDD with all files.

Don't create the tar file in the directory you are packing up:

tar -czf /tmp/workspace.tar.gz .

does the trick, except it will extract the files all over the current directory when you unpack. Better to do:

cd ..
tar -czf workspace.tar.gz workspace

or, if you don't know the name of the directory you were in:

base=$(basename $PWD)
cd ..
tar -czf $base.tar.gz $base

(This assumes that you didn't follow symlinks to get to where you are and that the shell doesn't try to second guess you by jumping backwards through a symlink - bash is not trustworthy in this respect. If you have to worry about that, use cd -P .. to do a physical change directory. Stupid that it is not the default behaviour in my view - confusing, at least, for those for whom cd .. never had any alternative meaning.)

One comment in the discussion says:

I [...] need to exclude the top directory and I [...] need to place the tar in the base directory.

The first part of the comment does not make much sense - if the tar file contains the current directory, it won't be created when you extract file from that archive because, by definition, the current directory already exists (except in very weird circumstances).

The second part of the comment can be dealt with in one of two ways:

1. Either: create the file somewhere else - /tmp is one possible location - and then move it back to the original location after it is complete.
2. Or: if you are using GNU Tar, use the --exclude=workspace.tar.gz option. The string after the = is a pattern - the example is the simplest pattern - an exact match. You might need to specify --exclude=./workspace.tar.gz if you are working in the current directory contrary to recommendations; you might need to specify --exclude=workspace/workspace.tar.gz if you are working up one level as suggested. If you have multiple tar files to exclude, use '*', as in --exclude=./*.gz.

Seven years later searches for vertical alignment still bring up this question, so I'll post another solution we have available to us now: flexbox positioning. Just set display:flex; justify-content: flex-end; flex-direction: column on the parent div (demonstrated in this fiddle as well):

#parentDiv
{
  display: flex;
  justify-content: flex-end;
  flex-direction: column;
  width:300px;
  height:300px;
  background-color:#ccc;
  background-repeat:repeat
}

const object1 = {
  a: 'something',
  b: 'something',
  c: 'something'
};

const key = 's';

// Object.keys(object1) will return array of the object keys ['a', 'b', 'c']

Object.keys(object1).indexOf(key) === -1 ? 'the key is not there' : 'yep the key is exist';

You are trying to run Java code with Python. In Python/Selenium, the org.openqa.selenium.interactions.Actions are reflected in ActionChains class:

from selenium.webdriver.common.action_chains import ActionChains

element = driver.find_element_by_id("my-id")

actions = ActionChains(driver)
actions.move_to_element(element).perform()

Or, you can also "scroll into view" via scrollIntoView():

driver.execute_script("arguments[0].scrollIntoView();", element)

If you are interested in the differences:

• scrollIntoView vs moveToElement

Simple solution to achieve "split in two" background:

background: linear-gradient(to left, #ff0000 50%, #0000ff 50%);

You can also use degrees as direction

background: linear-gradient(80deg, #ff0000 50%, #0000ff 50%);

    val fact_df = df.select($"data"(30) as "TopicTypeId", $"data"(31) as "TopicId",$"data"(21).cast(FloatType).as( "Data_Value_Std_Err")).rdd
    //Schema to be applied to the table
    val fact_schema = (new StructType).add("TopicTypeId", StringType).add("TopicId", StringType).add("Data_Value_Std_Err", FloatType)

    val fact_table = sqlContext.createDataFrame(fact_df, fact_schema).dropDuplicates()

Below is my code to get a picture to load into a PictureBox and Display a Picture name in to a TextBox without Extension.

private void browse_btn_Click(object sender, EventArgs e)
    {
        OpenFileDialog Open = new OpenFileDialog();
        Open.Filter = "image files|*.jpg;*.png;*.gif;*.icon;.*;";
        if (Open.ShowDialog() == DialogResult.OK)
        {
            imageLocation = Open.FileName.ToString();
            string picTureName = null;
            picTureName = Path.ChangeExtension(Path.GetFileName(imageLocation), null);

            pictureBox_Gift.ImageLocation = imageLocation;
            GiftName_txt.Text = picTureName.ToString();
            Savebtn.Enabled = true;
        }
    }

A callable is an object allows you to use round parenthesis ( ) and eventually pass some parameters, just like functions.

Every time you define a function python creates a callable object. In example, you could define the function func in these ways (it's the same):

class a(object):
    def __call__(self, *args):
        print 'Hello'

func = a()

# or ... 
def func(*args):
    print 'Hello'

You could use this method instead of methods like doit or run, I think it's just more clear to see obj() than obj.doit()

This is because you have the following code:

class JSONDeserializer
{
    Value JSONDeserializer::ParseValue(TDR type, const json_string& valueString);
};

This is not valid C++ but Visual Studio seems to accept it. You need to change it to the following code to be able to compile it with a standard compliant compiler (gcc is more compliant to the standard on this point).

class JSONDeserializer
{
    Value ParseValue(TDR type, const json_string& valueString);
};

The error come from the fact that JSONDeserializer::ParseValue is a qualified name (a name with a namespace qualification), and such a name is forbidden as a method name in a class.

If there is no existing method then I guess you can iterate from 0 to input.size()/2, taking each consecutive element and appending it to a new ArrayList.

EDIT: Actually, I think you can take that List and use it to instantiate a new ArrayList using one of the ArrayList constructors.

"Simple XML Serialization" Project

You may want to look at the Simple XML Serialization project. It is the closest thing I've found to the System.Xml.Serialization in .Net.

There's a third (and potentially much easier) option. If you want to spin up multiple instances of a single program, using a Unix-style command processor like Xargs or GNU Parallel can make that a fairly straightforward process.

There's a win32 Xargs clone called PPX2 that makes this fairly straightforward.

For instance, if you wanted to transcode a directory of video files, you could run the command:

dir /b *.mpg |ppx2 -P 4 -I {} -L 1 ffmpeg.exe -i "{}" -quality:v 1 "{}.mp4"

Picking this apart, dir /b *.mpg grabs a list of .mpg files in my current directory, the | operator pipes this list into ppx2, which then builds a series of commands to be executed in parallel; 4 at a time, as specified here by the -P 4 operator. The -L 1 operator tells ppx2 to only send one line of our directory listing to ffmpeg at a time.

After that, you just write your command line (ffmpeg.exe -i "{}" -quality:v 1 "{}.mp4"), and {} gets automatically substituted for each line of your directory listing.

It's not universally applicable to every case, but is a whole lot easier than using the batch file workarounds detailed above. Of course, if you're not dealing with a list of files, you could also pipe the contents of a textfile or any other program into the input of pxx2.

function zfill(num, len) {return (Array(len).join("0") + num).slice(-len);}

Another possibility that I encountered was that one of the packages in the repository ended up with a detached HEAD. If none of the answer here helps and you encounter a git status message like this you might have the same problem:

Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

        modified:   path/to/package (new commits)

Going into the path/to/package folder a git status should yield the following result:

HEAD detached at 7515f05

And the following command should then fix the issue, where master should be replaced by your local branch:

git checkout master

And you'll get a message that your local branch will be some amounts of commits behind the remote branch. git pull and you should be out of the woods!

You can just place your header and your RecyclerView in a NestedScrollView:

<android.support.v4.widget.NestedScrollView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        >

        <include
            layout="@layout/your_header"/>

        <android.support.v7.widget.RecyclerView
            android:id="@+id/list_recylclerview"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            />

    </LinearLayout>

</android.support.v4.widget.NestedScrollView>

In order for scrolling to work correctly, you need to disable nested scrolling on your RecyclerView:

myRecyclerView.setNestedScrollingEnabled(false);

%time% should work, provided enough time has elapsed between calls:

@echo OFF

@echo %time%
ping -n 1 -w 1 127.0.0.1 1>nul
@echo %time%

On my system I get the following output:

If You want to ensure, that your code is running with python2 and python3, use function input () in your script and add this to begin of your script:

from sys import version_info
if version_info.major == 3:
    pass
elif version_info.major == 2:
    try:
        input = raw_input
    except NameError:
        pass
else:
    print ("Unknown python version - input function not safe")

If the variable is declared (either with the var keyword, as a function argument, or as a global variable), I think the best way to do it is:

if (my_variable === undefined)

jQuery does it, so it's good enough for me :-)

Otherwise, you'll have to use typeof to avoid a ReferenceError.

If you expect undefined to be redefined, you could wrap your code like this:

(function(undefined){
    // undefined is now what it's supposed to be
})();

Or obtain it via the void operator:

const undefined = void 0;
// also safe

In Spark 2.4

To compare with one value:

df.filter(lower(trim($"col_name")) === "<value>").show()

To compare with collection of value:

df.filter($"col_name".isInCollection(new HashSet<>(Arrays.asList("value1", "value2")))).show()

I agree with the answer from zacherates.

But what you can do is to call intern() on your non-literal strings.

From zacherates example:

// ... but they are not the same object
new String("test") == "test" ==> false 

If you intern the non-literal String equality is true:

new String("test").intern() == "test" ==> true 

tips

in package.json:

"scripts": {
  "start": "set NODE_ENV=dev && node app.js"
 }

in app.js:

console.log(process.env.NODE_ENV) // dev
console.log(process.env.NODE_ENV === 'dev') // false
console.log(process.env.NODE_ENV.length) // 4 (including a space at the end) 

so, this may better:

"start": "set NODE_ENV=dev&& node app.js"

or

console.log(process.env.NODE_ENV.trim() === 'dev') // true

An excellent source for learning Ruby and Ruby on Rails is at http://www.teachmetocode.com. There are screencasts that cover the basics of Rails, along with a 6-part series on how to create a Twitter clone with Ruby on Rails.

You can also use Jadx - https://github.com/skylot/jadx. I have used all the tools mentioned in this page and found that Jadx works the best. The manifest file and other class files are converted to readable format as much as possible by this tool.

PS - http://www.javadecompilers.com/apk also uses the jadx decompiler to do the same work online. Simpler if you want to unarchive a single apk.

Cheers!

If you response is like {'customer':{'first_name':'John','last_name':'Cena'}}

var d = JSON.parse(response);
alert(d.customer.first_name); // contains "John"

Thanks,

I like Robert McMahan's answer the best here as it seems the easiest to make into sharable include files for any of your scripts to use. But it seems to have a flaw with the line if [[ -n ${variables[$argument_label]} ]] throwing the message, "variables: bad array subscript". I don't have the rep to comment, and I doubt this is the proper 'fix,' but wrapping that if in if [[ -n $argument_label ]] ; then cleans it up.

Here's the code I ended up with, if you know a better way please add a comment to Robert's answer.

Include File "flags-declares.sh"

# declaring a couple of associative arrays
declare -A arguments=();
declare -A variables=();

# declaring an index integer
declare -i index=1;

Include File "flags-arguments.sh"

# $@ here represents all arguments passed in
for i in "$@"
do
  arguments[$index]=$i;
  prev_index="$(expr $index - 1)";

  # this if block does something akin to "where $i contains ="
  # "%=*" here strips out everything from the = to the end of the argument leaving only the label
  if [[ $i == *"="* ]]
    then argument_label=${i%=*}
    else argument_label=${arguments[$prev_index]}
  fi

  if [[ -n $argument_label ]] ; then
    # this if block only evaluates to true if the argument label exists in the variables array
    if [[ -n ${variables[$argument_label]} ]] ; then
      # dynamically creating variables names using declare
      # "#$argument_label=" here strips out the label leaving only the value
      if [[ $i == *"="* ]]
        then declare ${variables[$argument_label]}=${i#$argument_label=} 
        else declare ${variables[$argument_label]}=${arguments[$index]}
      fi
    fi
  fi

  index=index+1;
done;

Your "script.sh"

. bin/includes/flags-declares.sh

# any variables you want to use here
# on the left left side is argument label or key (entered at the command line along with it's value) 
# on the right side is the variable name the value of these arguments should be mapped to.
# (the examples above show how these are being passed into this script)
variables["-gu"]="git_user";
variables["--git-user"]="git_user";
variables["-gb"]="git_branch";
variables["--git-branch"]="git_branch";
variables["-dbr"]="db_fqdn";
variables["--db-redirect"]="db_fqdn";
variables["-e"]="environment";
variables["--environment"]="environment";

. bin/includes/flags-arguments.sh

# then you could simply use the variables like so:
echo "$git_user";
echo "$git_branch";
echo "$db_fqdn";
echo "$environment";

One simple trick we use is to just call git add --all twice in a row.

For example, our Windows 7 commit script calls:

$ git add --all
$ git add --all

The first add treats the link as text and adds the folders for delete.

The second add traverses the link correctly and undoes the delete by restoring the files.

It's less elegant than some of the other proposed solutions but it is a simple fix to some of our legacy environments that got symlinks added.

If you are using ionic v1, the above solution won't work since ionic has enabled template caching as part of $ionicConfigProvider.

Work around for that is a bit hacky - you have to set cache to 0 in ionic.angular.js file:

$ionicConfigProvider.views.maxCache(0);

To jump between words and start/end of lines in iTerm2 pick one of the two solutions below.

1. Simple solution (recommended)

1. Open Preferences
2. Click "Profile" tab
3. Select a profile in the list on the left (eg "Default") and click "Keys" tab
4. Click the "Presets" dropdown and select "Natural Text Editing"

2. Mapping keys manually (Advanced)

If you don't want to use the "Natural Text Editing" preset mentioned above, you can map the keys you need manually:

1. Open Preferences
2. Click “Keys” tab
3. Click the [+] icon

You can now add the following keyboard shortcuts:

Move cursor one word left

• Keyboard shortcut: ? + ?
• Action: Send Hex Code
• Code: 0x1b 0x62

Move cursor one word right

• Keyboard Combination: ? + ?
• Action: Send Hex Code
• Code: 0x1b 0x66

Move cursor to beginning of line

• Keyboard Combination: ? + ?
• Action: Send Hex Code
• Code: 0x01

Move cursor to end of line

• Keyboard Combination: ? + ?
• Action: Send Hex Code
• Code: 0x05

Delete word

• Keyboard Combination: ? + ?Delete
• Action: Send Hex Code
• Code: 0x1b 0x08

Delete line

• Keyboard Combination: ? + ?Delete
• Action: Send Hex Code
• Code: 0x15

Undo

• Keyboard Combination: ? + z
• Action: Send Hex Code
• Code: 0x1f

Don't forget to remove the previous bindings:

• Open the “Profiles” tab
• Click the sub-tab ”Keys”
• Remove the mappings for key combinations ? + ? and ? + ?

Assuming you know the real directory the XML file lives in use Path.Combine, e.g.

var absolute_path = Path.Combine(directoryXmlLivesIn, "..\images\image.jpg");

If you want to get back the full path with any ..'s collapsed then you can use:

Path.GetFullPath((new Uri(absolute_path)).LocalPath);

HERE=$(cd $(dirname $BASH_SOURCE) && pwd)

where you get the full path with new_path=$(dirname ${BASH_SOURCE[0]}). You change current directory with cd new_path and then run pwd to get the full path to the current directory.

Using numpy, you can do:

y = x.astype(int)

If you were using a non-numpy array, you could use a list comprehension:

y = [int(val) for val in x]

Try something like:

WHERE (column LIKE '%this%' OR column LIKE '%that%') AND something = else

var x = $('#h_v').val();
alert(x);

If you want to take just two numbers after comma you can use the Math Class that give you the round function for example :

float value = 92.197354542F;
value = (float)System.Math.Round(value,2);         // value = 92.2;

Hope this Help
Cheers

import itertools

A = list(zip([1,3,5,7,9],[2,4,6,8,10]))
B = [1,3,5,7,9]+[2,4,6,8,10]
C = list(set([1,3,5,7,9] + [2,4,6,8,10]))

D = [1,3,5,7,9]
D.append([2,4,6,8,10])

E = [1,3,5,7,9]
E.extend([2,4,6,8,10])

F = []
for a in itertools.chain([1,3,5,7,9], [2,4,6,8,10]):
    F.append(a)


print ("A: " + str(A))
print ("B: " + str(B))
print ("C: " + str(C))
print ("D: " + str(D))
print ("E: " + str(E))
print ("F: " + str(F))

Output:

A: [(1, 2), (3, 4), (5, 6), (7, 8), (9, 10)]
B: [1, 3, 5, 7, 9, 2, 4, 6, 8, 10]
C: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
D: [1, 3, 5, 7, 9, [2, 4, 6, 8, 10]]
E: [1, 3, 5, 7, 9, 2, 4, 6, 8, 10]
F: [1, 3, 5, 7, 9, 2, 4, 6, 8, 10]

This is a simple method that can handle selection even if the list is long as well:

public View getView(final int position, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub
    Holder holder=new Holder();
    View rowView;
    rowView = inflater.inflate(R.layout.list_item, null);
    //Handle your items.
    //StringHolder.mSelectedItem is a public static variable.
    if(getItemId(position)==StringHolder.mSelectedItem){
        rowView.setBackgroundColor(Color.LTGRAY);

    }else{
        rowView.setBackgroundColor(Color.TRANSPARENT);
    }
    return rowView;
}

And then in your onclicklistener:

list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
            StringHolder.mSelectedItem = catagoryAdapter.getItemId(i-1);
            catagoryAdapter.notifyDataSetChanged();
.....

The Observable Collection constructor will take an IList or an IEnumerable.

If you find that you are going to do this a lot you can make a simple extension method:

    public static ObservableCollection<T> ToObservableCollection<T>(this IEnumerable<T> enumerable)
    {
        return new ObservableCollection<T>(enumerable);
    }

This can help others a lot!

First:

private static final String APP_DIR = Environment.getExternalStorageDirectory().getAbsolutePath() + "/MyAppFolderInStorage/";

private void install() {
    File file = new File(APP_DIR + fileName);

    if (file.exists()) {
        Intent intent = new Intent(Intent.ACTION_VIEW);
        String type = "application/vnd.android.package-archive";

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            Uri downloadedApk = FileProvider.getUriForFile(getContext(), "ir.greencode", file);
            intent.setDataAndType(downloadedApk, type);
            intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
        } else {
            intent.setDataAndType(Uri.fromFile(file), type);
            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        }

        getContext().startActivity(intent);
    } else {
        Toast.makeText(getContext(), "?File not found!", Toast.LENGTH_SHORT).show();
    }
}

Second: For android 7 and above you should define a provider in manifest like below!

    <provider
        android:name="android.support.v4.content.FileProvider"
        android:authorities="ir.greencode"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/paths" />
    </provider>

Third: Define path.xml in res/xml folder like below! I'm using this path for internal storage if you want to change it to something else there is a few way! You can go to this link: FileProvider

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="your_folder_name" path="MyAppFolderInStorage/"/>
</paths>

Forth: You should add this permission in manifest:

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

Allows an application to request installing packages. Apps targeting APIs greater than 25 must hold this permission in order to use Intent.ACTION_INSTALL_PACKAGE.

Please make sure the provider authorities are the same!

Use this command inside you Dockerfile to keep the container running in your K8s cluster:

• CMD tail -f /dev/null

A query's projection can only have one instance of a given name. As your WHERE clause shows, you have several tables with a column called ID. Because you are selecting * your projection will have several columns called ID. Or it would have were it not for the compiler hurling ORA-00918.

The solution is quite simple: you will have to expand the projection to explicitly select named columns. Then you can either leave out the duplicate columns, retaining just (say) COACHES.ID or use column aliases: coaches.id as COACHES_ID.

Perhaps that strikes you as a lot of typing, but it is the only way. If it is any comfort, SELECT * is regarded as bad practice in production code: explicitly named columns are much safer.

You can remove it from the repo and commit the change.

git rm .idea/ -r --cached
git add -u .idea/
git commit -m "Removed the .idea folder"

After that, you can push it to the remote and every checkout/clone after that will be ok.

Why do you need to state both x and y before the :?

Because it's a function definition and it needs to know what parameters the function accepts, and in what order. It can't just look at the expression and use the variables names in that, because some of those names you might want to use existing local or global variable values for, and even if it did that, it wouldn't know what order it should expect to get them.

Your error message means that Tk is calling your lambda with one argument, while your lambda is written to accept no arguments. If you don't need the argument, just accept one and don't use it. (Demosthenex has the code, I would have posted it but was beaten to it.)

I solved that problem on me after a very long try, I created another file named "parent_pom.xml" in child module file directory at local and pasted contents of parent_pom.xml,which is located at remote, to newly created "parent_pom.xml". It worked for me and error message has gone.

Your understanding is correct. However, if we walk through:

• (.*) will swallow the whole string;
• it will need to give back characters so that (\\d+) is satistifed (which is why 0 is captured, and not 3000);
• the last (.*) will then capture the rest.

I am not sure what the original intent of the author was, however.

Your vncserver have a configuration file somewher that set the display number. To do it automaticaly, one solution is to parse this file, extract the number and set it correctly. A simpler (better) is to have this display number set in a config script and use it in both your VNC server config and in your init scripts.

For sentOs, it's works for me At first stop service by sudo service jenkins stop

Than remove by sudo yum remove jenkins

Like Andrew said /exclude parameter of xcopy should be existing file that has list of excludes.

Documentation of xcopy says:

Using /exclude

List each string in a separate line in each file. If any of the listed strings match any part of the absolute path of the file to be copied, that file is then excluded from the copying process. For example, if you specify the string "\Obj\", you exclude all files underneath the Obj directory. If you specify the string ".obj", you exclude all files with the .obj extension.

Example:

xcopy c:\t1 c:\t2 /EXCLUDE:list-of-excluded-files.txt

and list-of-excluded-files.txt should exist in current folder (otherwise pass full path), with listing of files/folders to exclude - one file/folder per line. In your case that would be:

exclusion.txt

With .net 4 you could perhaps look at the ExpandoObject, however, don't use it for this simple case as what would have been compile-time errors become run-time errors.

class Program
{
    static void Main(string[] args)
    {
        dynamic employee, manager;

        employee = new ExpandoObject();
        employee.Name = "John Smith";
        employee.Age = 33;

        manager = new ExpandoObject();
        manager.Name = "Allison Brown";
        manager.Age = 42;
        manager.TeamSize = 10;

        WritePerson(manager);
        WritePerson(employee);
    }
    private static void WritePerson(dynamic person)
    {
        Console.WriteLine("{0} is {1} years old.",
                          person.Name, person.Age);
        // The following statement causes an exception
        // if you pass the employee object.
        // Console.WriteLine("Manages {0} people", person.TeamSize);
    }
}
// This code example produces the following output:
// John Smith is 33 years old.
// Allison Brown is 42 years old.

Something else worth mentioning is an anonymous type for within a method, but you need to create a class if you want to return it.

var MyStuff = new
    {
        PropertyName1 = 10,
        PropertyName2 = "string data",
        PropertyName3 = new ComplexType()
    };

Python resolves your variables with -- generally -- three namespaces available.

At any time during execution, there are at least three nested scopes whose namespaces are directly accessible: the innermost scope, which is searched first, contains the local names; the namespaces of any enclosing functions, which are searched starting with the nearest enclosing scope; the middle scope, searched next, contains the current module's global names; and the outermost scope (searched last) is the namespace containing built-in names.

There are two functions: globals and locals which show you the contents two of these namespaces.

Namespaces are created by packages, modules, classes, object construction and functions. There aren't any other flavors of namespaces.

In this case, the call to a function named x has to be resolved in the local name space or the global namespace.

Local in this case, is the body of the method function Foo.spam.

Global is -- well -- global.

The rule is to search the nested local spaces created by method functions (and nested function definitions), then search global. That's it.

There are no other scopes. The for statement (and other compound statements like if and try) don't create new nested scopes. Only definitions (packages, modules, functions, classes and object instances.)

Inside a class definition, the names are part of the class namespace. code2, for instance, must be qualified by the class name. Generally Foo.code2. However, self.code2 will also work because Python objects look at the containing class as a fall-back.

An object (an instance of a class) has instance variables. These names are in the object's namespace. They must be qualified by the object. (variable.instance.)

From within a class method, you have locals and globals. You say self.variable to pick the instance as the namespace. You'll note that self is an argument to every class member function, making it part of the local namespace.

See Python Scope Rules, Python Scope, Variable Scope.

ALTER session set NLS_LANGUAGE=’AMERICAN’;

More pythonic way:

df = data_set[['data_date', 'data_1', 'data_2']]
map(tuple,df.values)

Here is some code (it's actually not Timsort as I originally thought, but it does work well) that does the trick without any boxing/unboxing. In my tests, it works 3-4 times faster than using Collections.sort with a List wrapper around the array.

Alternatively to SQL, you can do this in Microsoft SQL Server Management Studio. Here are a few quick ways using the GUI:

First Way

Slow double-click on the column. The column name will become an editable text box.

Second Way

Right click on column and choose Rename from the context menu.

For example:

Third Way

This way is preferable for when you need to rename multiple columns in one go.

1. Right-click on the table that contains the column that needs renaming.
2. Click Design.
3. In the table design panel, click and edit the textbox of the column name you want to alter.

For example:

_{NOTE: I know OP specifically asked for SQL solution, thought this might help others :)}

Instead of using a bat file, you can simply create a Scheduled Task. Most of the time you define just one action. In this case, create two actions with the NET command. The first one to stop the service, the second one to start the service. Give them a STOP and START argument, followed by the service name.

In this example we restart the Printer Spooler service.

NET STOP "Print Spooler" 
NET START "Print Spooler"

Note: unfortunately NET RESTART <service name> does not exist.

input[name=username] { disabled: true; /* Does not work */ }

I know this question is quite old but for other users who come across this problem, I suppose the easiest way to disable input is simply by ':disabled'

<input type="text" name="username" value="admin" disabled />
<style type="text/css">
  input[name=username]:disabled {
    opacity: 0.5 !important; /* Fade effect */
    cursor: not-allowed; /* Cursor change to disabled state*/
  }
</style>

In reality, if you have some script to disable the input dynamically/automatically with javascript or jquery that would automatically disable based on the condition you add.

In jQuery for Example:

if (condition) {
// Make this input prop disabled state

Hope the answer in CSS helps.

This is not the exact answer to this question, but those who are not able to find setting popup. Their is two ways to open setting pop up.

The ASCII table contains 128 codes, with a total of 95 printable characters, of which only 52 characters are letters:

• [0-127] ASCII codes
  • [32-126] printable characters
    • [48-57] digits [0-9]
    • [65-90] uppercase letters [A-Z]
    • [97-122] lowercase letters [a-z]

You can use String.codePoints method to get a stream over int values of characters of this string and filter out non-ASCII characters:

String str1 = "A função, Ãugent";

String str2 = str1.codePoints()
        .filter(ch -> ch < 128)
        .mapToObj(Character::toString)
        .collect(Collectors.joining());

System.out.println(str2); // A funo, ugent

Or you can explicitly specify character ranges. For example filter out everything except letters:

String str3 = str1.codePoints()
        .filter(ch -> ch >= 'A' && ch <= 'Z'
                || ch >= 'a' && ch <= 'z')
        .mapToObj(Character::toString)
        .collect(Collectors.joining());

System.out.println(str3); // Afunougent

The whereNotIn method verifies that the given column's value is not contained in the given array:

$users = DB::table('users')
                    ->whereNotIn('id', [1, 2, 3])
                    ->get();

When the WSDL is available, it is just two steps you need to follow to invoke that web service.

Step 1: Generate the client side source from a WSDL2Java tool

Step 2: Invoke the operation using:

YourService service = new YourServiceLocator();
Stub stub = service.getYourStub();
stub.operation();

If you look further, you will notice that the Stub class is used to invoke the service deployed at the remote location as a web service. When invoking that, your client actually generates the SOAP request and communicates. Similarly the web service sends the response as a SOAP. With the help of a tool like Wireshark, you can view the SOAP messages exchanged.

However since you have requested more explanation on the basics, I recommend you to refer here and write a web service with it's client to learn it further.

In short, decoupling success callback function from the ajax function so later you can add your own handlers without modifying the original code (observer pattern).

The actual problem is not IE8, but the hacks that you use for earlier versions of IE.

IE8 is pretty close to be standards compliant, so you shouldn't need any hacks at all for it, perhaps only some tweaks. The problem is if you are using some hacks for IE6 and IE7; you will have to make sure that they only apply to those versions and not IE8.

I made the web site of our company compatible with IE8 a while ago. The only thing that I actually changed was adding the meta tag that tells IE that the pages are IE8 compliant...

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

Just add import CommonCrypto in your swift file.

Summarized

Adding:

android:layout_centerInParent="true"

just works on RelativeLayout, if one of the following attributes is also set for the view:

android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"

which alignes the child view to the parent view. The "center" is based on the axis of the alignement you have chosen:

left/right -> vertical

top/bottom -> horizontal

Setting the gravity of childs/content inside the view:

android:gravity="center"

is centering the child inside the parent view in any case, if there is no alignment set. Optional you can choose:

<!-- Axis to Center -->
android:gravity="center_horizontal"
android:gravity="center_vertical"

<!-- Alignment to set-->
android:gravity="top"
android:gravity="bottom"
android:gravity="left"
android:gravity="right"
android:gravity="fill"
...

Then there is:

android:layout_gravity="center"

which is centering the view itself inside it's parent

And at last you can add the following attribute to the parents view:

android:layout_centerHorizontal="true"
android:layout_centerVertical="true"

Yes, you need $(this) for jQuery functions, but when you want to access basic javascript methods of the element that don't use jQuery, you can just use this.

If you don't mind VBA, here is a function that will do it for you. Your call would be something like:

=CountRows(1:10) 

Function CountRows(ByVal range As range) As Long

Application.ScreenUpdating = False
Dim row As range
Dim count As Long

For Each row In range.Rows
    If (Application.WorksheetFunction.CountBlank(row)) - 256 <> 0 Then
        count = count + 1
    End If
Next

CountRows = count
Application.ScreenUpdating = True

End Function

How it works: I am exploiting the fact that there is a 256 row limit. The worksheet formula CountBlank will tell you how many cells in a row are blank. If the row has no cells with values, then it will be 256. So I just minus 256 and if it's not 0 then I know there is a cell somewhere that has some value.

private static MethodBase GetCallingMethod()
{
  return new StackFrame(2, false).GetMethod();
}

private static Type GetCallingType()
{
  return new StackFrame(2, false).GetMethod().DeclaringType;

The effect of the volatile keyword is approximately that each individual read or write operation on that variable is atomic.

Notably, however, an operation that requires more than one read/write -- such as i++, which is equivalent to i = i + 1, which does one read and one write -- is not atomic, since another thread may write to i between the read and the write.

The Atomic classes, like AtomicInteger and AtomicReference, provide a wider variety of operations atomically, specifically including increment for AtomicInteger.

On HDInsight I tried the hive --version, but it did not recognize the option or mention it in the help.

From this I would say I have Hive version 0.13 deployed, which is consistent with this list of versions https://hive.apache.org/downloads.html

Android Studio 4.1.1 has this bug,

In gradle-wrapper.properties

distributionUrl=https\://services.gradle.org/distributions/gradle-6.5-bin.zip

This won't download and always gives 'gradle cache corrupt' error, but a small change makes it work fine

distributionUrl=https\://services.gradle.org/distributions/gradle-6.5-all.zip

Now sync the gradle again and it's done.

I'm normally the one of the very few Python experts who steadfastly defends regular expressions (they have quite a bad reputation in the Python community), but this is not one of those cases -- accepting (say) '333.444.555.666' as an "IP address" is really bad, and if you need to do more checks after matching the RE, much of the point of using a RE is lost anyway. So, I second @Mark's recommendations heartily: IPy for generality and elegance (including support of IPv6 if you want!), string operations and int checks if you only need IPv4 (but, think twice about that limitation, and then think one more -- IPv6's time has way come!-):

def isgoodipv4(s):
    pieces = s.split('.')
    if len(pieces) != 4: return False
    try: return all(0<=int(p)<256 for p in pieces)
    except ValueError: return False

I'd far rather do that than a convoluted RE to match only numbers between 0 and 255!-)

I think the problem is the realpath of the file. For example your script is working on './', your file is inside the directory './xml'. So better check if the file exists or not, before you get filemtime or unlink it:

  function deleteOldFiles(){
    if ($handle = opendir('./xml')) {
        while (false !== ($file = readdir($handle))) { 

            if(preg_match("/^.*\.(xml|xsl)$/i", $file)){
              $fpath = 'xml/'.$file;
              if (file_exists($fpath)) {
                $filelastmodified = filemtime($fpath);

                if ( (time() - $filelastmodified ) > 24*3600){
                    unlink($fpath);
                }
              }
            }
        }
        closedir($handle); 
    }
  }

That is the function that I used for my project, and it works as expected.

function array_csv_download( $array, $filename = "export.csv", $delimiter=";" )
{
    header( 'Content-Type: application/csv' );
    header( 'Content-Disposition: attachment; filename="' . $filename . '";' );

    // clean output buffer
    ob_end_clean();

    $handle = fopen( 'php://output', 'w' );

    // use keys as column titles
    fputcsv( $handle, array_keys( $array['0'] ) );

    foreach ( $array as $value ) {
        fputcsv( $handle, $value , $delimiter );
    }

    fclose( $handle );

    // flush buffer
    ob_flush();

    // use exit to get rid of unexpected output afterward
    exit();
}

Surround it with an \mbox{}

Try to use

COUNTER=$((COUNTER+1))

instead of

COUNTER=$((COUNTER))

You can use as below:

string selected = cmbbox.Text;
MessageBox.Show(selected);

you can use pixels or percent.

<div id="container">
<img id="image" src="...">
</div>

css

#image
{
width:100%;
height:
}

In your string I see: 15.5859949000000662452.23862099999999 which is not a double (it has two decimal points). Perhaps it's just a legitimate input error?

You may also want to figure out if your last String will be empty, and account for that situation.

To download ISIN code data the only place I see this is on the ISIN organizations website, www.isin.org. try http://isin.org, they should have a function where you can easily download.

Let's say you have:

<a></a>

<(.*)> would match a></a where as <(.*?)> would match a. The latter stops after the first match of >. It checks for one or 0 matches of .* followed by the next expression.

The first expression <(.*)> doesn't stop when matching the first >. It will continue until the last match of >.

If you have 2 versions of Python (eg: 2.7.x and 3.6), you need do:

1. add the path of 2.x to system PATH
2. add the path of 3.x to system PATH
3. pip3 install --upgrade pip setuptools wheel

for example, in my .zshrc file:

export PATH=/usr/local/Cellar/python@2/2.7.15/bin:/usr/local/Cellar/python/3.6.5/bin:$PATH

You can exec command pip --version and pip3 --version check the pip from the special version. Because if don't add Python path to $PATH, and exec pip3 install --upgrade pip setuptools wheel, your pip will be changed to pip from python3, but the pip should from python2.x

theme root directory path code

 <?php $root_path = get_home_path(); ?> 
print "Path: ".$root_path;

Return "Path: /var/www/htdocs/" or "Path: /var/www/htdocs/wordpress/" if it is subfolder

Theme Root Path

 $theme_root = get_theme_root();
 echo $theme_root

Results:- /home/user/public_html/wp-content/themes

The short version is that you cannot use variable-width patterns in lookbehinds using Python's re module. There is no way to change this:

>>> import re
>>> re.sub("(?<=foo)bar(?=baz)", "quux", "foobarbaz")
'fooquuxbaz'
>>> re.sub("(?<=fo+)bar(?=baz)", "quux", "foobarbaz")

Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
    re.sub("(?<=fo+)bar(?=baz)", "quux", string)
  File "C:\Development\Python25\lib\re.py", line 150, in sub
    return _compile(pattern, 0).sub(repl, string, count)
  File "C:\Development\Python25\lib\re.py", line 241, in _compile
    raise error, v # invalid expression
error: look-behind requires fixed-width pattern

This means that you'll need to work around it, the simplest solution being very similar to what you're doing now:

>>> re.sub("(fo+)bar(?=baz)", "\\1quux", "foobarbaz")
'fooquuxbaz'
>>>
>>> # If you need to turn this into a callable function:
>>> def replace(start, replace, end, replacement, search):
        return re.sub("(" + re.escape(start) + ")" + re.escape(replace) + "(?=" + re.escape + ")", "\\1" + re.escape(replacement), search)

This doesn't have the elegance of the lookbehind solution, but it's still a very clear, straightforward one-liner. And if you look at what an expert has to say on the matter (he's talking about JavaScript, which lacks lookbehinds entirely, but many of the principles are the same), you'll see that his simplest solution looks a lot like this one.

You can use the new request method getSchemeAndHttpHost():

{{ app.request.getSchemeAndHttpHost() }}

Instead of having to choose whether to convert the string to int or float, you can simply add a 0 to it, and PHP will automatically convert the result to a numeric type.

// Being sure the string is actually a number
if (is_numeric($string))
    $number = $string + 0;
else // Let the number be 0 if the string is not a number
    $number = 0;

    <ul>
        <li><a href="">Home</a></li>
        <li><a href="">About</a></li>
        <li><a href="">Contact</a></li>
        <li><a href="">Menu</a></li>
        <li><a href="">Others</a></li>
    </ul>

.navigation {
    max-width: 700px;
    margin: 0 auto;

.navigation ul {
    list-style: none;
    display: table;
    width: 100%;
}
.navigation ul li {
    display: table-cell;
    text-align: center;
}
.navigation ul li a {
    padding: 5px 10px;
    width: 100%;
}

Omg so much cleaner.

It depends on your OS, but if you are on Windows XP, you need to go to Systems Properties, then Advanced, then Environment Variables, and include the php binary path to the %PATH% variable.

Locate it by browsing your WAMP directory. It's called php.exe

I think this should work .. :)

<input type="checkbox" name="Days[]" value="Daily">Daily<br>

exec 3>&1 1>>${LOG_FILE} 2>&1

would send stdout and stderr output into the log file, but would also leave you with fd 3 connected to the console, so you can do

echo "Some console message" 1>&3

to write a message just to the console, or

echo "Some console and log file message" | tee /dev/fd/3

to write a message to both the console and the log file - tee sends its output to both its own fd 1 (which here is the LOG_FILE) and the file you told it to write to (which here is fd 3, i.e. the console).

Example:

exec 3>&1 1>>${LOG_FILE} 2>&1

echo "This is stdout"
echo "This is stderr" 1>&2
echo "This is the console (fd 3)" 1>&3
echo "This is both the log and the console" | tee /dev/fd/3

would print

This is the console (fd 3)
This is both the log and the console

on the console and put

This is stdout
This is stderr
This is both the log and the console

into the log file.

personally strsplit / explode / strtok does not support word boundaries, so to get a more accute split use regular expression with the \w

preg_split('/[\s]+/',$string,1);

This would split words with boundaries to a limit of 1.

On newer versions of Android, I was receiving this error because the adapter was still discovering when I attempted to connect to the socket. Even though I called the cancelDiscovery method on the Bluetooth adapter, I had to wait until the callback to the BroadcastReceiver's onReceive() method was called with the action BluetoothAdapter.ACTION_DISCOVERY_FINISHED.

Once I waited for the adapter to stop discovery, then the connect call on the socket succeeded.

This is similar to an 'ls' but it does not take into account the prefix folder convention and will list the objects in the bucket. It's left up to the reader to filter out prefixes which are part of the Key name.

In Python 2:

from boto.s3.connection import S3Connection

conn = S3Connection() # assumes boto.cfg setup
bucket = conn.get_bucket('bucket_name')
for obj in bucket.get_all_keys():
    print(obj.key)

In Python 3:

from boto3 import client

conn = client('s3')  # again assumes boto.cfg setup, assume AWS S3
for key in conn.list_objects(Bucket='bucket_name')['Contents']:
    print(key['Key'])

  {
    "use strict";

Unless you tell the development server that it's running in development mode, it will assume you're using it in production and warn you not to. The development server is not intended for use in production. It is not designed to be particularly efficient, stable, or secure.

Enable development mode by setting the FLASK_ENV environment variable to development.

$ export FLASK_APP=example

If you're running in PyCharm (or probably any other IDE) you can set environment variables in the run configuration.

Development mode enables the debugger and reloader by default. If you don't want these, pass --no-debugger or --no-reloader to the run command.

That warning is just a warning though, it's not an error preventing your app from running. If your app isn't working, there's something else wrong with your code.

You will find the tomcat-users.xml in \Users\<Name>\AppData\Roaming\Netbeans\. It exists at least twice on your machine, depending on the number of Tomcat installations you have.

Simplistically malloc and free work like this:

malloc provides access to a process's heap. The heap is a construct in the C core library (commonly libc) that allows objects to obtain exclusive access to some space on the process's heap.

Each allocation on the heap is called a heap cell. This typically consists of a header that hold information on the size of the cell as well as a pointer to the next heap cell. This makes a heap effectively a linked list.

When one starts a process, the heap contains a single cell that contains all the heap space assigned on startup. This cell exists on the heap's free list.

When one calls malloc, memory is taken from the large heap cell, which is returned by malloc. The rest is formed into a new heap cell that consists of all the rest of the memory.

When one frees memory, the heap cell is added to the end of the heap's free list. Subsequent malloc's walk the free list looking for a cell of suitable size.

As can be expected the heap can get fragmented and the heap manager may from time to time, try to merge adjacent heap cells.

When there is no memory left on the free list for a desired allocation, malloc calls brk or sbrk which are the system calls requesting more memory pages from the operating system.

Now there are a few modification to optimize heap operations.

• For large memory allocations (typically > 512 bytes, the heap manager may go straight to the OS and allocate a full memory page.
• The heap may specify a minimum size of allocation to prevent large amounts of fragmentation.
• The heap may also divide itself into bins one for small allocations and one for larger allocations to make larger allocations quicker.
• There are also clever mechanisms for optimizing multi-threaded heap allocation.

Finally, I've defeated my CiSCO EAP-FAST corporate wifi network, and all our Android devices are now able to connect to it.

The walk-around I've performed in order to gain access to this kind of networks from an Android device are easiest than you can imagine.

There's a Wifi Config Editor in the Google Play Store you can use to "activate" the secondary CISCO Protocols when you are setting up a EAP wifi connection.

Its name is Wifi Config Advanced Editor.

• First, you have to setup your wireless network manually as close as you can to your "official" corporate wifi parameters.

• Save it.

• Go to the WCE and edit the parameters of the network you have created in the previous step.

• There are 3 or 4 series of settings you should activate in order to force the Android device to use them as a way to connect (the main site I think you want to visit is Enterprise Configuration, but don't forget to check all the parameters to change them if needed.
  As a suggestion, even if you have a WPA2 EAP-FAST Cipher, try LEAP in your setup. It worked for me as a charm.

• When you finished to edit the config, go to the main Android wifi controller, and force to connect to this network.

• Do not Edit the network again with the Android wifi interface.

I have tested it on Samsung Galaxy 1 and 2, Note mobile devices, and on a Lenovo Thinkpad Tablet.

In simplest terms,

When you say you are forking a repository, you are basically creating a copy of the original repository under your GitHub ID in your GitHub account.

and

When you say you are cloning a repository, you are creating a local copy of the original repository in your system (PC/laptop) directly without having a copy in your GitHub account.

Very simple. Just cast your char as an int.

char character = 'a';    
int ascii = (int) character;

In your case, you need to get the specific Character from the String first and then cast it.

char character = name.charAt(0); // This gives the character 'a'
int ascii = (int) character; // ascii is now 97.

Though cast is not required explicitly, but its improves readability.

int ascii = character; // Even this will do the trick.

if you have multiple parameters use the syntax as below. I have a bat file with script as below:

start "dummyTitle" [/options] D:\path\ProgramName.exe Param1 Param2 Param3 
start "dummyTitle" [/options] D:\path\ProgramName.exe Param4 Param5 Param6 

This will open multiple consoles.

Bootstrap uses CSS3 transitions so progress bars are automatically animated when you set the width of .bar trough javascript / jQuery.

There is no agreed upon naming convention for HTML and CSS. But you could structure your nomenclature around object design. More specifically what I call Ownership and Relationship.

Ownership

Keywords that describe the object, could be separated by hyphens.

car-new-turned-right

Keywords that describe the object can also fall into four categories (which should be ordered from left to right): Object, Object-Descriptor, Action, and Action-Descriptor.

car - a noun, and an object
new - an adjective, and an object-descriptor that describes the object in more detail
turned - a verb, and an action that belongs to the object
right - an adjective, and an action-descriptor that describes the action in more detail

Note: verbs (actions) should be in past-tense (turned, did, ran, etc).

Relationship

Objects can also have relationships like parent and child. The Action and Action-Descriptor belongs to the parent object, they don't belong to the child object. For relationships between objects you could use an underscore.

car-new-turned-right_wheel-left-turned-left

• car-new-turned-right (follows the ownership rule)
• wheel-left-turned-left (follows the ownership rule)
• car-new-turned-right_wheel-left-turned-left (follows the relationship rule)

Final notes:

• Because CSS is case-insensitive, it's better to write all names in lower-case (or upper-case); avoid camel-case or pascal-case as they can lead to ambiguous names.
• Know when to use a class and when to use an id. It's not just about an id being used once on the web page. Most of the time, you want to use a class and not an id. Web components like (buttons, forms, panels, ...etc) should always use a class. Id's can easily lead to naming conflicts, and should be used sparingly for namespacing your markup. The above concepts of ownership and relationship apply to naming both classes and ids, and will help you avoid naming conflicts.
• If you don't like my CSS naming convention, there are several others as well: Structural naming convention, Presentational naming convention, Semantic naming convention, BEM naming convention, OCSS naming convention, etc.

In my case I was facing the problem because in my tomcat process specific keystore was given using

-Djavax.net.ssl.trustStore=/pathtosomeselfsignedstore/truststore.jks

Wheras I was importing the certificate to the cacert of JRE/lib/security and the changes were not reflecting. Then I did below command where /tmp/cert1.test contains the certificate of the target server

keytool -import -trustcacerts -keystore /pathtosomeselfsignedstore/truststore.jks -storepass password123 -noprompt -alias rapidssl-myserver -file /tmp/cert1.test

We can double check if the certificate import is successful

keytool -list -v -keystore /pathtosomeselfsignedstore/truststore.jks

and see if your taget server is found against alias rapidssl-myserver

To give gradient color to UIView (swift 4.2)

func makeGradientLayer(`for` object : UIView, startPoint : CGPoint, endPoint : CGPoint, gradientColors : [Any]) -> CAGradientLayer {
        let gradient: CAGradientLayer = CAGradientLayer()
        gradient.colors = gradientColors
        gradient.locations = [0.0 , 1.0]
        gradient.startPoint = startPoint
        gradient.endPoint = endPoint
        gradient.frame = CGRect(x: 0, y: 0, w: object.frame.size.width, h: object.frame.size.height)
        return gradient
    }

How to use

let start : CGPoint = CGPoint(x: 0.0, y: 1.0)
let end : CGPoint = CGPoint(x: 1.0, y: 1.0)

let gradient: CAGradientLayer = makeGradientLayer(for: cell, startPoint: start, endPoint: end, gradientColors: [
                    UIColor(red:0.92, green:0.07, blue:0.4, alpha:1).cgColor,
                    UIColor(red:0.93, green:0.11, blue:0.14, alpha:1).cgColor
                    ])

self.vwTemp.layer.insertSublayer(gradient, at: 0)

A point I think should be added to what other answers mention is that while

List<Dog> isn't-a List<Animal> in Java

it is also true that

A list of dogs is-a list of animals in English (under a reasonable interpretation)

The way the OP's intuition works - which is completely valid of course - is the latter sentence. However, if we apply this intuition we get a language that is not Java-esque in its type system: Suppose our language does allow adding a cat to our list of dogs. What would that mean? It would mean that the list ceases to be a list of dogs, and remains merely a list of animals. And a list of mammals, and a list of quadrapeds.

To put it another way: A List<Dog> in Java does not mean "a list of dogs" in English, it means "a list which can have dogs, and nothing else".

More generally, OP's intuition lends itself towards a language in which operations on objects can change their type, or rather, an object's type(s) is a (dynamic) function of its value.

This error comes when you append this line os.path.join(os.path.dirname(__file__)) in python interactive shell.

Python Shell doesn't detect current file path in __file__ and it's related to your filepath in which you added this line

So you should write this line os.path.join(os.path.dirname(__file__)) in file.py. and then run python file.py, It works because it takes your filepath.

An "incomplete class" is one declared but not defined. E.g.

class Wielrenner;

as opposed to

class Wielrenner
{
    /* class members */
};

You need to #include "wielrenner.h" in dokter.ccp

I believe that you can make it scroll by using the trackball, which might be achieved programmatically through selection methods eventually, but it's just an idea. I know that the trackball method typically works, but as for the exact way to do this and make it work from code, I do not sure.

You can use .on() to capture multiple events and then test for touch on the screen, e.g.:

$('#selector')
.on('touchstart mousedown', function(e){
  e.preventDefault();
  var touch = e.touches[0];
  if(touch){
    // Do some stuff
  }
  else {
    // Do some other stuff
  }
});

On Windows , this helped me https://packaging.python.org/tutorials/installing-packages

On Windows you can find the user base binary directory by running python -m site --user-site and replacing site-packages with Scripts. For example, this could return C:\Users\Username\AppData\Roaming\Python36\site-packages so you would need to set your PATH to include C:\Users\Username\AppData\Roaming\Python36\Scripts. You can set your user PATH permanently in the Control Panel. You may need to log out for the PATH changes to take effect.

I have created some simple function you can use to convert time to any timezone :

function convertTimeToLocal($datetime,$timezone='Europe/Dublin') {
        $given = new DateTime($datetime, new DateTimeZone("UTC"));

        $output = $given->format("Y-m-d"); //can change as per your requirement
        return $output;
}

Might be easier to simply make sure that duplicates are not added to the list.

if(items.IndexOf(new_item) < 0) 
    items.add(new_item)

Correct Syntax: select spelling was wrong

INSERT INTO courses (name, location, gid)
SELECT name, location, 'whatever you want' 
FROM courses 
WHERE cid = $ci 

This is how you do it in 2020:

var s = "ABCDEFGH";
var first5 = s.AsSpan(0, 5);

A Span<T> points directly to the memory of the string, avoiding allocating a temporary string. Of course, any subsequent method asking for a string requires a conversion:

Console.WriteLine(first5.ToString());

Though, these days many .NET APIs allow for spans. Stick to them if possible!

Note: If targeting .NET Framework add a reference to the System.Memory package, but don't expect the same superb performance.

To check if a string variable contains a valid email address, the easiest way is to test it against a regular expression. There is a good discussion of various regex's and their trade-offs at regular-expressions.info.

Here is a relatively simple one that leans on the side of allowing some invalid addresses through: ^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,6}$

How you can use regular expressions depends on the version of iOS you are using.

iOS 4.x and Later

You can use NSRegularExpression, which allows you to compile and test against a regular expression directly.

iOS 3.x

Does not include the NSRegularExpression class, but does include NSPredicate, which can match against regular expressions.

NSString *emailRegex = ...;
NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
BOOL isValid = [emailTest evaluateWithObject:checkString];

Read a full article about this approach at cocoawithlove.com.

iOS 2.x

Does not include any regular expression matching in the Cocoa libraries. However, you can easily include RegexKit Lite in your project, which gives you access to the C-level regex APIs included on iOS 2.0.

I discovered that the accepted answer actually doesn't always work, because \\Z may occur in the file. Another problem is that if you don't have the correct charset a whole bunch of unexpected things may happen which may cause the scanner to read only a part of the file.

The solution is to use a delimiter which you are certain will never occur in the file. However, this is theoretically impossible. What we CAN do, is use a delimiter that has such a small chance to occur in the file that it is negligible: such a delimiter is a UUID, which is natively supported in Java.

String content = new Scanner(file, "UTF-8")
    .useDelimiter(UUID.randomUUID().toString()).next();

Use input.nextLine(); instead of input.next();

Update: AdoptOpenJDK has changed its name to Adoptium, as part of its move to the Eclipse Foundation.

OpenJDK ? source code
Adoptium/AdoptOpenJDK ? builds

Difference between OpenJDK and AdoptOpenJDK

The first provides source-code, the other provides builds of that source-code.

• OpenJDK is an open-source project providing source-code (not builds) of an implementation of the Java platform as defined by:
  • the Java Specifications
  • Java Specification Request (JSR) documents published by Oracle via the Java Community Process
  • JDK Enhancement Proposal (JEP) documents published by Oracle via the OpenJDK project
• AdoptOpenJDK is an organization founded by some prominent members of the Java community aimed at providing binary builds and installers at no cost for users of Java technology.

Several vendors of Java & OpenJDK

Adoptium of the Eclipse Foundation, formerly known as AdoptOpenJDK, is only one of several vendors distributing implementations of the Java platform. These include:

• Eclipse Foundation (Adoptium/AdoptOpenJDK)
• Azul Systems
• Oracle
• Red Hat / IBM
• BellSoft
• SAP
• Amazon AWS
• … and more

See this flowchart of mine to help guide you in picking a vendor for an implementation of the Java platform. Click/tap to zoom.

Another resource: This comparison matrix by Azul Systems is useful, and seems true and fair to my mind.

Here is a list of considerations and motivations to consider in choosing a vendor and implementation.

Some vendors offer you a choice of JIT technologies.

        $ul.attr('data-parent', ts);

Faster clearing than Arrays.fill is with this (From Fast Serialization Lib). I just use arrayCopy (is native) to clear the array:

static Object[] EmptyObjArray = new Object[10000];

public static void clear(Object[] arr) {
    final int arrlen = arr.length;
    clear(arr, arrlen);
}

public static void clear(Object[] arr, int arrlen) {
    int count = 0;
    final int length = EmptyObjArray.length;
    while( arrlen - count > length) {
        System.arraycopy(EmptyObjArray,0,arr,count, length);
        count += length;
    }
    System.arraycopy(EmptyObjArray,0,arr,count, arrlen -count);
}

I also found another one for SQL Server:

SELECT COLUMN_NAME
FROM INFORMATION_SCHEMA.KEY_COLUMN_USAGE
WHERE OBJECTPROPERTY(OBJECT_ID(CONSTRAINT_SCHEMA + '.' + QUOTENAME(CONSTRAINT_NAME)), 'IsPrimaryKey') = 1
AND TABLE_NAME = 'TableName' AND TABLE_SCHEMA = 'Schema'

Meanwhile this can be solved through a decorator in combination with Object.freeze or Object.defineProperty, I'm using this, it's a little bit prettier than using tons of getters. You can copy/paste this directly TS Playground to see it in action. - There are two options

Make individual fields "final"

The following decorator converts both, annotated static and non-static fields to "getter-only-properties".

Note: If an instance-variable with no initial value is annotated @final, then the first assigned value (no matter when) will be the final one.

// example
class MyClass {
    @final
    public finalProp: string = "You shall not change me!";

    @final
    public static FINAL_FIELD: number = 75;

    public static NON_FINAL: string = "I am not final."
}

var myInstance: MyClass = new MyClass();
myInstance.finalProp = "Was I changed?";
MyClass.FINAL_FIELD = 123;
MyClass.NON_FINAL = "I was changed.";

console.log(myInstance.finalProp);  // => You shall not change me!
console.log(MyClass.FINAL_FIELD);   // => 75
console.log(MyClass.NON_FINAL);     // => I was changed.

The Decorator: Make sure you include this in your code!

/**
* Turns static and non-static fields into getter-only, and therefor renders them "final".
* To use simply annotate the static or non-static field with: @final
*/
function final(target: any, propertyKey: string) {
    const value: any = target[propertyKey];
    // if it currently has no value, then wait for the first setter-call
    // usually the case with non-static fields
    if (!value) {
        Object.defineProperty(target, propertyKey, {
            set: function (value: any) {
                Object.defineProperty(this, propertyKey, {
                    get: function () {
                        return value;
                    },
                    enumerable: true,
                    configurable: false
                });
            },
            enumerable: true,
            configurable: true
        });
    } else { // else, set it immediatly
        Object.defineProperty(target, propertyKey, {
            get: function () {
                return value;
            },
            enumerable: true
        });
    }
}

As an alternative to the decorator above, there would also be a strict version of this, which would even throw an Error when someone tried to assign some value to the field with "use strict"; being set. (This is only the static part though)

/**
 * Turns static fields into getter-only, and therefor renders them "final".
 * Also throws an error in strict mode if the value is tried to be touched.
 * To use simply annotate the static field with: @strictFinal
 */
function strictFinal(target: any, propertyKey: string) {
    Object.defineProperty(target, propertyKey, {
        value: target[propertyKey],
        writable: false,
        enumerable: true
    });
}

Make every static field "final"

Possible Downside: This will only work for ALL statics of that class or for none, but cannot be applied to specific statics.

/**
* Freezes the annotated class, making every static 'final'.
* Usage:
* @StaticsFinal
* class MyClass {
*      public static SOME_STATIC: string = "SOME_STATIC";
*      //...
* }
*/
function StaticsFinal(target: any) {
    Object.freeze(target);
}

// Usage here
@StaticsFinal
class FreezeMe {
    public static FROZEN_STATIC: string = "I am frozen";
}

class EditMyStuff {
    public static NON_FROZEN_STATIC: string = "I am frozen";
}

// Test here
FreezeMe.FROZEN_STATIC = "I am not frozen.";
EditMyStuff.NON_FROZEN_STATIC = "I am not frozen.";

console.log(FreezeMe.FROZEN_STATIC); // => "I am frozen."
console.log(EditMyStuff.NON_FROZEN_STATIC); // => "I am not frozen."

The solution is so simple:

Replace type "Submit" with button

<input type="button" value="Submit" onclick="this.form.submit()" />

Are they identical?

> identical(A,C)
[1] FALSE

Which elements disagree:

> which(A != C)
[1] 2 4

For Kotlin mb better to use this:

fun String.decode(): String {
    return Base64.decode(this, Base64.DEFAULT).toString(charset("UTF-8"))
}

fun String.encode(): String {
    return Base64.encodeToString(this.toByteArray(charset("UTF-8")), Base64.DEFAULT)
}

Example:

Log.d("LOGIN", "TEST")
Log.d("LOGIN", "TEST".encode())
Log.d("LOGIN", "TEST".encode().decode())

select * from table1 where table1.col1 in (select table2.col1 from table2)

Assuming col1 is the primary key column and this will give all rows in table1 respective to the table2 column 1.

select * from table1 where table1.col1 not in (select table2.col1 from table2)

Hope this helps

You need the oracle client driver installed for those classes to work.

There might be 3rd party connection frameworks out there that can handle Oracle, perhaps someone else might know of some specific ones.

Running this little piece of code allowed me to understand the order function

x <- c(3, 22, 5, 1, 77)

cbind(
  index=1:length(x),
  rank=rank(x),
  x, 
  order=order(x), 
  sort=sort(x)
)

     index rank  x order sort
[1,]     1    2  3     4    1
[2,]     2    4 22     1    3
[3,]     3    3  5     3    5
[4,]     4    1  1     2   22
[5,]     5    5 77     5   77

Reference: http://r.789695.n4.nabble.com/I-don-t-understand-the-order-function-td4664384.html

For strings, you can use string.c_str() which will return you a const char*, which can be treated as an array, example:

const char* strdata = str.c_str();

for (int i = 0; i < str.length(); ++i)
    cout << i << strdata[i];

With pure html (no JS), you can't really substitute a radio-button for an image (at least, I don't think you can). You could, though use the following to make the same connection to the user:

<form action="" method="post">
    <fieldset>
       <input type="radio" name="feeling" id="feelingSad" value="sad" /><label for="feelingSad"><img src="path/to/sad.png" /></label>
       <label for="feelingHappy"><input type="radio" name="feeling" id="feelingHappy" value="happy" /><img src="path/to/happy.png" /></label>
    </fieldset>
</form>

The code below solved it for me:

@Override
public void onDestroyView() {
    if (getView() != null) {
        ViewGroup parent = (ViewGroup) getView().getParent();
        parent.removeAllViews();
    }
    super.onDestroyView();
}

Note: The error was from my fragment class and by overriding the onDestroy method like this, I could solve it.

var promise = $interval(function(){
    if($location.path() == '/landing'){
        $rootScope.$emit('testData',"test");
        $interval.cancel(promise);
    }
},2000);

you should divide hours by 24 not 11
like this:
select to_char(sysdate - 2/24, 'dd-mon-yyyy HH24') from dual

You can use this implementation that ExecutorService provides

invokeAll(Collection<? extends Callable<T>> tasks,long timeout, TimeUnit unit)
as

executor.invokeAll(Arrays.asList(task), 2 , TimeUnit.SECONDS);

However, in my case, I could not as Arrays.asList took extra 20ms.

For me, This error was because i had a prepare segue step that wasn't applicable to the segue that was being done.

long story:

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {

        let gosetup = segue.destination as! Update
        gosetup.wherefrom = updatestring

    }

This was being done to all segue when it was only for one. So i create a boolean and placed the gosetup inside it.

In short:

Type python in a command prompt

Simply open the command prompt (Win + R) and type cmd and in the command prompt then typing python will give you all necessary information regarding versions:

It is used to influence sorting in the CSS cascade when sorting by origin is done. It has nothing to do with specificity like stated here in other answers.

Here is the priority from lowest to highest:

1. browser styles
2. user style sheet declarations (without !important)
3. author style sheet declarations (without !important)
4. !important author style sheets
5. !important user style sheets

After that specificity takes place for the rules still having a finger in the pie.

Below can be 2 reasons for this issue:

1. Backup taken on SQL 2012 and Restore Headeronly was done in SQL 2008 R2

2. Backup media is corrupted.

If we run below command, we can find actual error always:

restore headeronly
from disk = 'C:\Users\Public\Database.bak'

Give complete location of your database file in the quot

Hope it helps

I found this question when I got the same error for a different reason.

My issue was that my Gulp hadn't picked up on the fact that I had declared a new module and I needed to manually re-run Gulp.

In case .empty() doesn't work for you, which is for me

function SetDropDownToEmpty() 
{           
$('#dropdown').find('option').remove().end().append('<option value="0"></option>');
$("#dropdown").trigger("liszt:updated");          
}

$(document).ready(
SetDropDownToEmpty() ;
)

Similar as they are, merge! and store treat existing hashes differently depending on keynames, and will therefore affect your preference. Other than that from a syntax standpoint, merge!'s key: "value" syntax closely matches up against JavaScript and Python. I've always hated comma-separating key-value pairs, personally.

hash = {}
hash.merge!(key: "value")
hash.merge!(:key => "value")
puts hash

{:key=>"value"}

hash = {}
hash.store(:key, "value")
hash.store("key", "value")
puts hash

{:key=>"value", "key"=>"value"}

I don't think this DateTimePicker has been mentioned before:

A WPF DateTimePicker That Works Like the One in Winforms

That one is in VB and has some bugs. I converted it to C# and made a new version with bug fixes.

Note: I used the Calendar control in WPFToolkit so that I could use .NET 3.5 instead of .NET 4. If you are using .NET 4, just remove references to "wpftc" in the XAML.

NOTE: I wrote this answer in Jun 2013, so it's bit dated nowadays. Many things changed in Android platform since version 6 (Marshmallow, released late 2015), making the whole problem more/less obsolete. However I believe this post can still be worth reading as general problem analysis approach example.

Exception you are getting (SecurityException: Permission denied (missing INTERNET permission?)), clearly indicates that you are not allowed to do networking. That's pretty indisputable fact. But how can this happen? Usually it's either due to missing <uses-permission android:name="android.permission.INTERNET" /> entry in your AndroidManifest.xml file or, as internet permission is granted at installation not at run time, by long standing, missed bug in Android framework that causes your app to be successfully installed, but without expected permission grant.

My Manifest is correct, so how can this happen?

Theoretically, presence of uses-permission in Manifest perfectly fulfills the requirement and from developer standpoint is all that's needed to be done to be able to do networking. Moreover, since permissions are shown to the user during installation, the fact your app ended installed on user's device means s/he granted what you asked for (otherwise installation is cancelled), so assumption that if your code is executed then all requested permissions are granted is valid. And once granted, user cannot revoke the permission other way than uninstalling the app completely as standard Android framework (from AOSP) offers no such feature at the moment.

But things are getting more tricky if you also do not mind your app running on rooted devices too. There're tools available in Google Play your users can install to control permission granted to installed apps at run-time - for example: Permissions Denied and others. This can also be done with CyanogenMod, vendor brand (i.e. LG's) or other custom ROM, featuring various type of "privacy managers" or similar tools.

So if app is blocked either way, it's basically blocked intentionally by the user and if so, it is really more user problem in this case (or s/he do not understand what certain options/tools really do and what would be the consequences) than yours, because standard SDK (and most apps are written with that SDK in mind) simply does not behave that way. So I strongly doubt this problem occurs on "standard", non-rooted device with stock (or vendor like Samsung, HTC, Sony etc) ROM.

I do not want to crash...

Properly implemented permission management and/org blocking must deal with the fact that most apps may not be ready for the situation where access to certain features is both granted and not accessible at the same time, as this is kind of contradiction where app uses manifest to request access at install time. Access control done right should must make all things work as before, and still limit usability using techniques in scope of expected behavior of the feature. For example, when certain permission is granted (i.e. GPS, Internet access) such feature can be made available from the app/user perspective (i.e. you can turn GPS on. or try to connect), the altered implementation can provide no real data - i.e. GPS can always return no coordinates, like when you are indoor or have no satellite "fix". Internet access can granted as before, but you can make no successful connection as there's no data coverage or routing. Such scenarios should be expected in normal usage as well, therefore it should be handled by the apps already. As this simply can happen during normal every day usage, any crash in such situation should be most likely be related to application bugs.

We lack too much information about the environment on which this problem occurs to diagnose problem w/o guessing, but as kind of solution, you may consider using setDefaultUncaughtExceptionHandler() to catch such unexpected exceptions in future and i.e. simply show user detailed information what permission your app needs instead of just crashing. Please note that using this will most likely conflict with tools like Crittercism, ACRA and others, so be careful if you use any of these.

Notes

Please be aware that android.permission.INTERNET is not the only networking related permission you may need to declare in manifest in attempt to successfully do networking. Having INTERNET permission granted simply allows applications to open network sockets (which is basically fundamental requirement to do any network data transfer). But in case your network stack/library would like to get information about networks as well, then you will also need android.permission.ACCESS_NETWORK_STATE in your Manifest (which is i.e. required by HttpUrlConnection client (see tutorial).

Addendum (2015-07-16)

Please note that Android 6 (aka Marshmallow) introduced completely new permission management mechanism called Runtime Permissions. It gives user more control on what permission are granted (also allows selective grant) or lets one revoke already granted permissions w/o need to app removal:

This [...] introduces a new permissions model, where users can now directly manage app permissions at runtime. This model gives users improved visibility and control over permissions, while streamlining the installation and auto-update processes for app developers. Users can grant or revoke permissions individually for installed apps.

However, the changes do not affect INTERNET or ACCESS_NETWORK_STATE permissions, which are considered "Normal" permissions. The user does not need to explicitly grant these permission.

See behavior changes description page for details and make sure your app will behave correctly on newer systems too. It's is especially important when your project set targetSdk to at least 23 as then you must support new permissions model (detailed documentation). If you are not ready, ensure you keep targetSdk to at most 22 as this ensures even new Android will use old permission system when your app is installed.

Based on the git documentation the best way is:

1. be sure the actual origin path:

git remote -v

3. Then make the change with:

git remote set-url origin

where url-repository is the same URL that we get from the clone option.

As an addition to user1471935's suggestion:

To instantiate a generic class by using a constructor with one or more parameters, you can now use the Activator class.

T instance = Activator.CreateInstance(typeof(T), new object[] {...}) 

The list of objects are the parameters you want to supply. According to Microsoft:

CreateInstance [...] creates an instance of the specified type using the constructor that best matches the specified parameters.

There's also a generic version of CreateInstance (CreateInstance<T>()) but that one also does not allow you to supply constructor parameters.

The easiest way that I found for adding a column to a DataFrame was to use the "add" function. Here's a snippet of code, also with the output to a CSV file. Note that including the "columns" argument allows you to set the name of the column (which happens to be the same as the name of the np.array that I used as the source of the data).

#  now to create a PANDAS data frame
df = pd.DataFrame(data = FF_maxRSSBasal, columns=['FF_maxRSSBasal'])
# from here on, we use the trick of creating a new dataframe and then "add"ing it
df2 = pd.DataFrame(data = FF_maxRSSPrism, columns=['FF_maxRSSPrism'])
df = df.add( df2, fill_value=0 )
df2 = pd.DataFrame(data = FF_maxRSSPyramidal, columns=['FF_maxRSSPyramidal'])
df = df.add( df2, fill_value=0 )
df2 = pd.DataFrame(data = deltaFF_strainE22, columns=['deltaFF_strainE22'])
df = df.add( df2, fill_value=0 )
df2 = pd.DataFrame(data = scaled, columns=['scaled'])
df = df.add( df2, fill_value=0 )
df2 = pd.DataFrame(data = deltaFF_orientation, columns=['deltaFF_orientation'])
df = df.add( df2, fill_value=0 )
#print(df)
df.to_csv('FF_data_frame.csv')

Firefox contains a dns cache. To disable the DNS cache:

1. Open your browser
2. Type in about:config in the address bar
3. Right click on the list of Properties and select New > Integer in the Context menu
4. Enter 'network.dnsCacheExpiration' as the preference name and 0 as the integer value

When disabled, Firefox will use the DNS cache provided by the OS.

You want to do:

i= items.erase(i);

That will correctly update the iterator to point to the location after the iterator you removed.

Here's a really simple & concise ES6 function to do this:

const titleCase = (str) => {
  return str.replace(/\w\S*/g, (t) => { return t.charAt(0).toUpperCase() + t.substr(1).toLowerCase() });
}

export default titleCase;

Works well included in a utilities folder and used as follows:

import titleCase from './utilities/titleCase.js';

const string = 'my title & string';

console.log(titleCase(string)); //-> 'My Title & String'

Use Java 8's removeIf(),

To remove safely,

letters.removeIf(x -> !x.equals("A"));

It's possible to use:

res.redirect('your/404/path.html');

In the recent Python version, subprocess has a big change. It offers a brand-new class Popen to handle os.popen1|2|3|4.

The new subprocess.Popen()

import subprocess
subprocess.Popen('ls -la', shell=True)

Its arguments:

subprocess.Popen(args, 
                bufsize=0, 
                executable=None, 
                stdin=None, stdout=None, stderr=None, 
                preexec_fn=None, close_fds=False, 
                shell=False, 
                cwd=None, env=None, 
                universal_newlines=False, 
                startupinfo=None, 
                creationflags=0)

Simply put, the new Popen includes all the features which were split into 4 separate old popen.

The old popen:

Method  Arguments
popen   stdout
popen2  stdin, stdout
popen3  stdin, stdout, stderr
popen4  stdin, stdout and stderr

Comparable defines a natural ordering. What this means is that you're defining it when one object should be considered "less than" or "greater than".

Suppose you have a bunch of integers and you want to sort them. That's pretty easy, just put them in a sorted collection, right?

TreeSet<Integer> m = new TreeSet<Integer>(); 
m.add(1);
m.add(3);
m.add(2);
for (Integer i : m)
... // values will be sorted

But now suppose I have some custom object, where sorting makes sense to me, but is undefined. Let's say, I have data representing districts by zipcode with population density, and I want to sort them by density:

public class District {
  String zipcode; 
  Double populationDensity;
}

Now the easiest way to sort them is to define them with a natural ordering by implementing Comparable, which means there's a standard way these objects are defined to be ordered.:

public class District implements Comparable<District>{
  String zipcode; 
  Double populationDensity;
  public int compareTo(District other)
  {
    return populationDensity.compareTo(other.populationDensity);
  }
}

Note that you can do the equivalent thing by defining a comparator. The difference is that the comparator defines the ordering logic outside the object. Maybe in a separate process I need to order the same objects by zipcode - in that case the ordering isn't necessarily a property of the object, or differs from the objects natural ordering. You could use an external comparator to define a custom ordering on integers, for example by sorting them by their alphabetical value.

Basically the ordering logic has to exist somewhere. That can be -

• in the object itself, if it's naturally comparable (extends Comparable -e.g. integers)

• supplied in an external comparator, as in the example above.

I know that this isn't an answer to the initial question ... but you often want to clip the inner content of that rounded corner border you just created.

Chris Cavanagh has come up with an excellent way to do just this.

I have tried a couple different approaches to this ... and I think this one rocks.

Here is the xaml below:

If you do not want to go the previous page i.e. do not let the user go back to the login screen once authorization is done, then you can use;

 App.Current.MainPage = new HomePage();

If you want to enable back functionality, just use

Navigation.PushModalAsync(new HomePage())

main() {
    double a;
    a=3669.0;
    int b;
    b=a;
    printf("b is %d",b);
  
}

output is :b is 3669

when you write b=a; then its automatically converted in int

This is called Implicit Type Conversion Read more here https://www.geeksforgeeks.org/implicit-type-conversion-in-c-with-examples/

Simply casting to an int truncates the float, which if your system internally represent 2.0 as 1.9999999999, you will not get what you expect. The various printf conversions deal with this and properly round the number when converting. So to get a more accurate value, the conversion is even more complicated than you might first expect:

package main

import (
    "fmt"
    "strconv"
)

func main() {
    floats := []float64{1.9999, 2.0001, 2.0}
    for _, f := range floats {
        t := int(f)
        s := fmt.Sprintf("%.0f", f)
        if i, err := strconv.Atoi(s); err == nil {
            fmt.Println(f, t, i)
        } else {
            fmt.Println(f, t, err)
        }
    }
}
