I'm learning Algorithm right now, so i wonder how bisect module writes. Here is the code from bisect module about inserting an item into sorted list, which uses dichotomy:
def insort_right(a, x, lo=0, hi=None):
"""Insert item x in list a, and keep it sorted assuming a is sorted.
If x is already in a, insert it to the right of the rightmost x.
Optional args lo (default 0) and hi (default len(a)) bound the
slice of a to be searched.
"""
if lo < 0:
raise ValueError('lo must be non-negative')
if hi is None:
hi = len(a)
while lo < hi:
mid = (lo+hi)//2
if x < a[mid]:
hi = mid
else:
lo = mid+1
a.insert(lo, x)
If you do not want to use numpy,
sorted(range(len(seq)), key=seq.__getitem__)
is fastest, as demonstrated here.
It might be a bit too heavyweight for you, but GlazedLists has a SortedList that is perfect to use as the model of a table or JList
You can do like this:
SELECT convert(datetime, convert(date, '27-09-2013', 103), 103)
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')
One of the reasons of your problem could be the password policy you are using.
And if there is no such policy of yours then check your settings for the password properties in the DEFAULT
profile with the following query:
SELECT resource_name, limit
FROM dba_profiles
WHERE profile = 'DEFAULT'
AND resource_type = 'PASSWORD';
And If required, you just need to change the PASSWORD_LIFE_TIME
to unlimited
with the following query:
ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED;
And this Link might be helpful for your problem.
For people with a similar question and find this post (like I did); you can do this even without lastrow if your dataset is formatted as a table.
Range("tablename[columnname]").Formula = "=G3&"",""&L3"
Making it a true one liner. Hope it helps someone!
In your link function, do this:
// link function
function (scope, element, attrs) {
var myEl = angular.element(element[0].querySelector('.list-scrollable'));
}
Also, in your link function, don't name your scope
variable using a $
. That is an angular convention that is specific to built in angular services, and is not something that you want to use for your own variables.
Another way ( longer ) In VB.net [ Say 2300 Start and 0700 Finish next day ]
If tsStart > tsFinish Then
' Take Hours difference and adjust accordingly
tsDifference = New TimeSpan((24 - tsStart.Hours) + tsFinish.Hours, 0, 0)
' Add Minutes to Difference
tsDifference = tsDifference.Add(New TimeSpan(0, Math.Abs(tsStart.Minutes - tsFinish.Minutes), 0))
' Add Seonds to Difference
tsDifference = tsDifference.Add(New TimeSpan(0, 0, Math.Abs(tsStart.Seconds - tsFinish.Seconds)))
Just do System.out.println(e.getActionCommand());
inside actionPerformed(ActionEvent e)
function. This will tell you which command is just performed.
or
if(e.getActionCommand().equals("Add")){
System.out.println("Add button pressed");
}
Do this:
if (denominator == 0) throw new ArithmeticException("denominator == 0");
ArithmeticException is the exception which is normally thrown when you divide by 0.
To see the detailed log you need to put two lines in the production.rb
file:
config.logger = Logger.new(STDOUT)
config.logger.level = Logger::DEBUG
and then by running
heroku logs -t
you can see the detailed logs.
public int getAge(Date dateOfBirth)
{
Calendar now = Calendar.getInstance();
Calendar dob = Calendar.getInstance();
dob.setTime(dateOfBirth);
if (dob.after(now))
{
throw new IllegalArgumentException("Can't be born in the future");
}
int age = now.get(Calendar.YEAR) - dob.get(Calendar.YEAR);
if (now.get(Calendar.DAY_OF_YEAR) < dob.get(Calendar.DAY_OF_YEAR))
{
age--;
}
return age;
}
You can use date:'yyyy-MM-dd'
pipe
curDate=new Date();
<p>{{curDate | date:'yyyy-MM-dd'}}</p>
use #include "ClasseAusiliaria.c"

This is an example of the greatest-n-per-group
problem that has appeared regularly on StackOverflow.
Here's how I usually recommend solving it:
SELECT c.*, p1.*
FROM customer c
JOIN purchase p1 ON (c.id = p1.customer_id)
LEFT OUTER JOIN purchase p2 ON (c.id = p2.customer_id AND
(p1.date < p2.date OR (p1.date = p2.date AND p1.id < p2.id)))
WHERE p2.id IS NULL;
Explanation: given a row p1
, there should be no row p2
with the same customer and a later date (or in the case of ties, a later id
). When we find that to be true, then p1
is the most recent purchase for that customer.
Regarding indexes, I'd create a compound index in purchase
over the columns (customer_id
, date
, id
). That may allow the outer join to be done using a covering index. Be sure to test on your platform, because optimization is implementation-dependent. Use the features of your RDBMS to analyze the optimization plan. E.g. EXPLAIN
on MySQL.
Some people use subqueries instead of the solution I show above, but I find my solution makes it easier to resolve ties.
If Elasticsearch cluster is not accessible (e.g. behind firewall), but Kibana is:

I tried invalidating cache, it didnt work for me.
However, I tried removing the jdk from Platform Settings and added it back and it worked.
Here's how to do it.
Project Settings -> SDKs -> Select the SDK -> Remove (-) -> Add it back again (+)
package com;
public class _index {
public static void main(String[] args) {
String s1="be proud to be an indian";
char ch=s1.charAt(s1.indexOf('e'));
int count = 0;
for(int i=0;i<s1.length();i++) {
if(s1.charAt(i)=='e'){
System.out.println("number of E:=="+ch);
count++;
}
}
System.out.println("Total count of E:=="+count);
}
}
If you're into C# and VB.Net and don't mind open source then you could use SharpDevelop. It does a pretty good job!
This should work because it uses List as you don't know how many lines will be there in the file and also they may change later.
BufferedReader in = new BufferedReader(new FileReader("path/of/text"));
String str=null;
ArrayList<String> lines = new ArrayList<String>();
while((str = in.readLine()) != null){
lines.add(str);
}
String[] linesArray = lines.toArray(new String[lines.size()]);
Unfortunately to be able to use the extension modules provided by others you'll be forced to use the official compiler to compile Python. These are:
Visual Studio 2008 for Python 2.7. See: https://docs.python.org/2.7/using/windows.html#compiling-python-on-windows
Visual Studio 2010 for Python 3.4. See: https://docs.python.org/3.4/using/windows.html#compiling-python-on-windows
Alternatively, you can use MinGw to compile extensions in a way that won't depend on others.
See: https://docs.python.org/2/install/#gnu-c-cygwin-MinGW or https://docs.python.org/3.4/install/#gnu-c-cygwin-mingw
This allows you to have one compiler to build your extensions for both versions of Python, Python 2.x and Python 3.x.

You could also add an offset if you want to use negative indexes:
uint8_t l_matrix[10][20];
uint8_t (*matrix_ptr)[20] = l_matrix+5;
matrix_ptr[-4][1]=7;
If your compiler gives an error or warning you could use:
uint8_t (*matrix_ptr)[20] = (uint8_t (*)[20]) l_matrix;
Note: this only answers part of the question.
If you just want to know the maximum number of sessions allowed, then you can execute in sqlplus, as sysdba:
SQL> show parameter sessions
This gives you an output like:

java_soft_sessionspace_limit integer 0
license_max_sessions integer 0
license_sessions_warning integer 0
sessions integer 248
shared_server_sessions integer
The sessions parameter is the one what you want.
If you want an recent copy of npgsql, then go here
This can be installed via package manager console as
PM> Install-Package Npgsql
Here you go: ES5
var test = 'Hello World';
if( test.indexOf('World') >= 0){
// Found world
}
With ES6 best way would be to use includes
function to test if the string contains the looking work.
const test = 'Hello World';
if (test.includes('World')) {
// Found world
}
Also look at log4net, which makes logging to 1 or more event stores — whether it's the console, the Windows event log, a text file, a network pipe, a SQL database, etc. — pretty trivial. You can even filter stuff in its configuration, for instance, so that only log records of a particular severity (say ERROR or FATAL) from a single component or assembly are directed to a particular event store.

Bootstrap sets the height of the navbar automatically to 50px. The padding above and below links is set to 15px. I think that bootstrap is adding padding to your logo.
You can either remove some of the padding above and below your logo or you can add more padding above and below links.
Adding more padding should look something like this:
nav.navbar-inverse>li>a {
padding-top: 25px;
padding-bottom: 25px;
}
I vote for the dictionary.
I find that if I make a function that returns anything more than 2-3 variables I'll fold them up in a dictionary. Otherwise I tend to forget the order and content of what I'm returning.
Also, introducing a 'special' structure makes your code more difficult to follow. (Someone else will have to search through the code to find out what it is)
If your concerned about type look up, use descriptive dictionary keys, for example, 'x-values list'.
def g(x):
y0 = x + 1
y1 = x * 3
y2 = y0 ** y3
return {'y0':y0, 'y1':y1 ,'y2':y2 }
Not to be horribly pedantic, but if you are internationalising the code it might be more useful to have the facility to get the short date for a given culture, e.g.:-
using System.Globalization;
using System.Threading;
...
var currentCulture = Thread.CurrentThread.CurrentCulture;
try {
Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture("en-us");
string shortDateString = DateTime.Now.ToShortDateString();
// Do something with shortDateString...
} finally {
Thread.CurrentThread.CurrentCulture = currentCulture;
}
Though clearly the "m/dd/yyyy" approach is considerably neater!!
For multicolumn listbox extract data from any column of selected row by
listboxControl.List(listboxControl.ListIndex,col_num)
where col_num is required column ( 0 for first column)
Just do it simple (tested with v1.3.15):
<article ng-controller="ctrl1 as c1">
<label>Change name here:</label>
<input ng-model="c1.sData.name" />
<h1>Control 1: {{c1.sData.name}}, {{c1.sData.age}}</h1>
</article>
<article ng-controller="ctrl2 as c2">
<label>Change age here:</label>
<input ng-model="c2.sData.age" />
<h1>Control 2: {{c2.sData.name}}, {{c2.sData.age}}</h1>
</article>
<script>
var app = angular.module("MyApp", []);
var dummy = {name: "Joe", age: 25};
app.controller("ctrl1", function () {
this.sData = dummy;
});
app.controller("ctrl2", function () {
this.sData = dummy;
});
</script>
I had this error once and I found out the origin:
I was using a gcc compiler and my file was called CLIENT.C
despite I was doing a C program and not a C++ program.
gcc recognizes the .C
extension as C++ program and .c
extension as C program (be careful to the small c and big C).
So I renamed my file CLIENT.c
program and it worked.
I had this same issue.I updated to buildToolsVersion "23.0.3" It all of a sudden worked. Hope this helps anyone having this issue.
I had this problem. If your app has a black background and you have a lot of RadioButtons that are invisible due to the background, it is complicated to edit the android: buttonTint of each one, the best solution is to change the parent theme in your styles.xml file
I changed
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
to
<style name="AppTheme" parent="Theme.AppCompat.NoActionBar">
So the RadioButtons' circles became a lighter shade of gray and now they are visible even with a black background.
This is my style.xml file:
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.NoActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
You could try this:
$in_str = 'this is a test';
$hex_ary = array();
foreach (str_split($in_str) as $chr) {
$hex_ary[] = sprintf("%02X", ord($chr));
}
echo implode(' ',$hex_ary);
You can use itertools.cycle
:
>>> from itertools import cycle
>>> lis = [[10,13,17],[3,5,1],[13,11,12]]
>>> cyc = cycle((-1, 1))
>>> 50 + sum(x*next(cyc) for x in lis[0]) # lis[0] is [10,13,17]
36
Here the generator expression inside sum
would return something like this:
>>> cyc = cycle((-1, 1))
>>> [x*next(cyc) for x in lis[0]]
[-10, 13, -17]
You can also use zip
here:
>>> cyc = cycle((-1, 1))
>>> [x*y for x, y in zip(lis[0], cyc)]
[-10, 13, -17]
Works only on Windows:
import winreg
import itertools
def serial_ports() -> list:
path = 'HARDWARE\\DEVICEMAP\\SERIALCOMM'
key = winreg.OpenKey(winreg.HKEY_LOCAL_MACHINE, path)
ports = []
for i in itertools.count():
try:
ports.append(winreg.EnumValue(key, i)[1])
except EnvironmentError:
break
return ports
if __name__ == "__main__":
ports = serial_ports()
I usually get it from the toString() return value. It works in differently accessed DOM elements:
var a = document.querySelector('a');
var img = document.createElement('img');
document.body.innerHTML += '<div id="newthing"></div>';
var div = document.getElementById('newthing');
Object.prototype.toString.call(a); // "[object HTMLAnchorElement]"
Object.prototype.toString.call(img); // "[object HTMLImageElement]"
Object.prototype.toString.call(div); // "[object HTMLDivElement]"
Then the relevant piece:
Object.prototype.toString.call(...).split(' ')[1].slice(0, -1);
It works in Chrome, FF, Opera, Edge, IE9+ (in older IE it return "[object Object]").
Your web.xml
ends with <web-app>

Subclass the ArrayAdapter and override the method getView() to return your own view that contains the contents that you want to display.
Dason K. and I have the pacman package that can do this nicely. The function p_load

Using ruby 2.4 you can do the same thing using transform_values
, this feature extracted from rails to ruby.
h = {a: 1, b: 2, c: 3}
h.transform_values { |v| v * 10 }
#=> {a: 10, b: 20, c: 30}
If both the list are too big and when we use lamda expression then it will take a long time to fetch . Better to use linq in this case to fetch parameters list:
var items = (from x in parameters
join y in myStrings on x.Source equals y
select x)
.ToList();
select year(current_timestamp)
In this case a[4]
is the 5th
integer in the array a
, ap
is a pointer to integer, so you are assigning an integer to a pointer and that's the warning.
So ap
now holds 45
and when you try to de-reference it (by doing *ap
) you are trying to access a memory at address 45, which is an invalid address, so your program crashes.
You should do ap = &(a[4]);
or ap = a + 4;
In c
array names decays to pointer, so a
points to the 1st element of the array.
In this way, a
is equivalent to &(a[0])
.
You can change this in your CSS with the property padding
:
.navbar-nav > li{
padding-left:30px;
padding-right:30px;
}
Also you can set margin
.navbar-nav > li{
margin-left:30px;
margin-right:30px;
}
You have to use Enum.Parse to get the object value from Enum, after that you have to change the object value to specific enum value. Casting to enum value can be do by using Convert.ChangeType. Please have a look on following code snippet
public T ConvertStringValueToEnum<T>(string valueToParse){
return Convert.ChangeType(Enum.Parse(typeof(T), valueToParse, true), typeof(T));
}
I found a way that works for me. It is not 100% exact but it eliminates all strings that contain more than just the word I am looking for because I check for the string not containing individual spaces too. By the way you don't need these " ". jQuery knows you are looking for a string. Make sure you only have one space in the :contains( ) part otherwise it won't work.
<p>hello</p>
<p>hello world</p>
$('p:contains(hello):not(:contains( ))').css('font-weight', 'bold');
And yes I know it won't work if you have stuff like <p>helloworld</p>
I had the same problem (don't know why).
This fix requires access to an uncorrupted remote copy of the repository, and will keep your locally working copy intact.
But it has some drawbacks:
Execute these commands from the parent directory above your repo (replace 'foo' with the name of your project folder):
cp -R foo foo-backup
git clone [email protected]:foo foo-newclone
rm -rf foo/.git
mv foo-newclone/.git foo
rm -rf foo-newclone
On Windows you will need to use:
copy
instead of cp -R
rmdir /S
instead of rm -rf
move
instead of mv
Now foo has its original .git
subdirectory back, but all the local changes are still there. git status
, commit
, pull
, push
, etc. work again as they should.
It's impossible to say without seeing your actual code. Likely the reason is a code path through your function that doesn't execute a return
statement. When the code goes down that path, the function ends with no value returned, and so returns None
.
Updated: It sounds like your code looks like this:
def b(self, p, data):
current = p
if current.data == data:
return True
elif current.data == 1:
return False
else:
self.b(current.next, data)
That else clause is your None
path. You need to return the value that the recursive call returns:
else:
return self.b(current.next, data)
BTW: using recursion for iterative programs like this is not a good idea in Python. Use iteration instead. Also, you have no clear termination condition.
find supports wildcard matches, just add a *

xsl:apply-templates
is usually (but not necessarily) used to process all or a subset of children of the current node with all applicable templates. This supports the recursiveness of XSLT application which is matching the (possible) recursiveness of the processed XML.
xsl:call-template
on the other hand is much more like a normal function call. You execute exactly one (named) template, usually with one or more parameters.
So I use xsl:apply-templates
if I want to intercept the processing of an interesting node and (usually) inject something into the output stream. A typical (simplified) example would be
<xsl:template match="foo">
<bar>
<xsl:apply-templates/>
</bar>
</xsl:template>
whereas with xsl:call-template
I typically solve problems like adding the text of some subnodes together, transforming select nodesets into text or other nodesets and the like - anything you would write a specialized, reusable function for.
As an additional remark to your specific question text:
<xsl:call-template name="nodes"/>
This calls a template which is named 'nodes':
<xsl:template name="nodes">...</xsl:template>
This is a different semantic than:
<xsl:apply-templates select="nodes"/>
...which applies all templates to all children of your current XML node whose name is 'nodes'.
Notes:
git status --ignored
.gitignore
files?")git clean -ndX
works on older gits, displaying a preview of what ignored files could be removed (without removing anything)Also interesting (mentioned in qwertymk's answer), you can also use the git check-ignore -v
command, at least on Unix (doesn't work in a CMD Windows session)
git check-ignore *
git check-ignore -v *
The second one displays the actual rule of the .gitignore
which makes a file to be ignored in your git repo.
On Unix, using "What expands to all files in current directory recursively?" and a bash4+:
git check-ignore **/*
(or a find -exec
command)
Note: https://stackoverflow.com/users/351947/Rafi B. suggests in the comments to avoid the (risky) globstar:
git check-ignore -v $(find . -type f -print)
Make sure to exclude the files from the .git/
subfolder though.

fprintf(stderr, "%s: --ignored needs some exclude pattern\n",
argv[0]);
exc_given
?
It turns out it need one more parameter after the -i
to actually list anything:
Try:
git ls-files -i --exclude-from=[Path_To_Your_Global].gitignore
(but that would only list your cached (non-ignored) object, with a filter, so that is not quite what you want)
Example:
$ cat .git/ignore
# ignore objects and archives, anywhere in the tree.
*.[oa]
$ cat Documentation/.gitignore
# ignore generated html files,
*.html
# except foo.html which is maintained by hand
!foo.html
$ git ls-files --ignored \
--exclude='Documentation/*.[0-9]' \
--exclude-from=.git/ignore \
--exclude-per-directory=.gitignore
Actually, in my 'gitignore' file (called 'exclude'), I find a command line that could help you:
F:\prog\git\test\.git\info>type exclude
# git ls-files --others --exclude-from=.git/info/exclude
# Lines that start with '#' are comments.
# For a project mostly in C, the following would be a good set of
# exclude patterns (uncomment them if you want to use them):
# *.[oa]
# *~
So....
git ls-files --ignored --exclude-from=.git/info/exclude
git ls-files -i --exclude-from=.git/info/exclude
git ls-files --others --ignored --exclude-standard
git ls-files -o -i --exclude-standard
should do the trick.
(Thanks to honzajde pointing out in the comments that git ls-files -o -i --exclude-from...
does not include cached files: only git ls-files -i --exclude-from...
(without -o
) does.)
As mentioned in the ls-files man page, --others
is the important part, in order to show you non-cached, non-committed, normally-ignored files.
--exclude_standard
is not just a shortcut, but a way to include all standard "ignored patterns" settings.
exclude-standard
Add the standard git exclusions:.git/info/exclude
,.gitignore
in each directory, and theuser's global exclusion file
.

Try this trick .. use css shadow with (inset) option and make the deep 200px for example
Code:
box-shadow: inset 0px 0px 277px 3px #4c3f37;
.
Also for all browsers:
-moz-box-shadow: inset 0px 0px 47px 3px #4c3f37;
-webkit-box-shadow: inset 0px 0px 47px 3px #4c3f37;
box-shadow: inset 0px 0px 277px 3px #4c3f37;
and increase number to make fill your box :)
Enjoy!

That depends on the nature of the information you want to return.
If it is a single integer value, you can use the return
statement
create proc myproc
as
begin
return 1
end
go
declare @i int
exec @i = myproc
If you have a non integer value, or a number of scalar values, you can use output parameters
create proc myproc
@a int output,
@b varchar(50) output
as
begin
select @a = 1, @b='hello'
end
go
declare @i int, @j varchar(50)
exec myproc @i output, @j output
If you want to return a dataset, you can use insert exec
create proc myproc
as
begin
select name from sysobjects
end
go
declare @t table (name varchar(100))
insert @t (name)
exec myproc
You can even return a cursor but that's just horrid so I shan't give an example :)
If you are doing a lot of functionality based on scroll position, Scroll magic (http://scrollmagic.io/) is built entirely for this purpose.
It makes it easy to trigger JS based on when the user reaches certain elements when scrolling. It also integrates with the GSAP animation engine (https://greensock.com/) which is great for parallax scrolling websites
Refining upon the answers found here I came up with the following:
getCurrentScript.js
var getCurrentScript = function () {
if (document.currentScript) {
return document.currentScript.src;
} else {
var scripts = document.getElementsByTagName('script');
return scripts[scripts.length-1].src;
}
};
module.exports = getCurrentScript;
getCurrentScriptPath.js
var getCurrentScript = require('./getCurrentScript');
var getCurrentScriptPath = function () {
var script = getCurrentScript();
var path = script.substring(0, script.lastIndexOf('/'));
return path;
};
module.exports = getCurrentScriptPath;
BTW: I'm using CommonJS module format and bundling with webpack.
Add this to the scope - https://www.googleapis.com/auth/userinfo.profile
And after authorization is done, get the information from - https://www.googleapis.com/oauth2/v1/userinfo?alt=json
It has loads of stuff - including name, public profile url, gender, photo etc.
Try this instead:
var responseObject = proxy.CallService(new RequestObject
{
Data = "misc. data",
Guid = new Guid.NewGuid()
});
This will generate a 'real' Guid value. When you new a reference type, it will give you the default value (which in this case, is all zeroes for a Guid).
When you create a new Guid, it will initialize it to all zeroes, which is the default value for Guid. It's basically the same as creating a "new" int (which is a value type but you can do this anyways):
Guid g1; // g1 is 00000000-0000-0000-0000-000000000000
Guid g2 = new Guid(); // g2 is 00000000-0000-0000-0000-000000000000
Guid g3 = default(Guid); // g3 is 00000000-0000-0000-0000-000000000000
Guid g4 = Guid.NewGuid(); // g4 is not all zeroes
Compare this to doing the same thing with an int:
int i1; // i1 is 0
int i2 = new int(); // i2 is 0
int i3 = default(int); // i3 is 0
For proper functional programming and chaining purposes an invention of Array.prototype.insert()
is essential. Actually splice could have been perfect if it had returned the mutated array instead of a totally meaningless empty array. So here it goes
Array.prototype.insert = function(i,...rest){_x000D_
this.splice(i,0,...rest)_x000D_
return this_x000D_
}_x000D_
_x000D_
var a = [3,4,8,9];_x000D_
document.write("<pre>" + JSON.stringify(a.insert(2,5,6,7)) + "</pre>");
_x000D_
Well ok the above with the Array.prototype.splice()
one mutates the original array and some might complain like "you shouldn't modify what doesn't belong to you" and that might turn out to be right as well. So for the public welfare i would like to give another Array.prototype.insert()
which doesn't mutate the original array. Here it goes;
Array.prototype.insert = function(i,...rest){_x000D_
return this.slice(0,i).concat(rest,this.slice(i));_x000D_
}_x000D_
_x000D_
var a = [3,4,8,9],_x000D_
b = a.insert(2,5,6,7);_x000D_
console.log(JSON.stringify(a));_x000D_
console.log(JSON.stringify(b));
_x000D_
OK I found it.
=LARGE($E$4:$E$9;A12)
=large(array, k)
Array Required. The array or range of data for which you want to determine the k-th largest value.
K Required. The position (from the largest) in the array or cell range of data to return.
Wouldn't unlinking it and creating the new one do the same thing in the end anyway?
I wanted to be able to easily let users create a default profile for PowerShell to override some settings, and ended up with the following one-liner (multiple statements yes, but can be pasted into PowerShell and executed at once, which was the main goal):
cls; [string]$filePath = $profile; [string]$fileContents = '<our standard settings>'; if(!(Test-Path $filePath)){md -Force ([System.IO.Path]::GetDirectoryName($filePath)) | Out-Null; $fileContents | sc $filePath; Write-Host 'File created!'; } else { Write-Warning 'File already exists!' };
For readability, here's how I would do it in a .ps1 file instead:
cls; # Clear console to better notice the results
[string]$filePath = $profile; # Declared as string, to allow the use of texts without plings and still not fail.
[string]$fileContents = '<our standard settings>'; # Statements can now be written on individual lines, instead of semicolon separated.
if(!(Test-Path $filePath)) {
New-Item -Force ([System.IO.Path]::GetDirectoryName($filePath)) | Out-Null; # Ignore output of creating directory
$fileContents | Set-Content $filePath; # Creates a new file with the input
Write-Host 'File created!';
}
else {
Write-Warning "File already exists! To remove the file, run the command: Remove-Item $filePath";
};
For anyone reading the example in "A Swift Tour" chapter of "The Swift Programming Language" and looking for a way to simplify the simpleDescription() method, converting the enum itself to String by doing String(self)
will do it:
enum Rank: Int
{
case Ace = 1 //required otherwise Ace will be 0
case Two, Three, Four, Five, Six, Seven, Eight, Nine, Ten
case Jack, Queen, King
func simpleDescription() -> String {
switch self {
case .Ace, .Jack, .Queen, .King:
return String(self).lowercaseString
default:
return String(self.rawValue)
}
}
}
The default dbpath for mongodb is /data/db
.
There is no default config file, so you will either need to specify this when starting mongod
with:
mongod --config /etc/mongodb.conf
.. or use a packaged install of MongoDB (such as for Redhat or Debian/Ubuntu) which will include a config file path in the service definition.
Note: to check the dbpath and command-line options for a running mongod
, connect via the mongo
shell and run:
db.serverCmdLineOpts()
In particular, if a custom dbpath
is set it will be the value of:
db.serverCmdLineOpts().parsed.dbpath // MongoDB 2.4 and older
db.serverCmdLineOpts().parsed.storage.dbPath // MongoDB 2.6+
RANK and DENSE_RANK have already been suggested - depending on your requirements, you might also consider ROW_NUMBER():
select * from (
select e.*, row_number() over (order by sal desc) rn from emp e
)
where rn = 2;
The difference between RANK(), DENSE_RANK() and ROW_NUMBER() boils down to:
So, if you only want one employee (even if there are several with the 2nd highest salary), I'd recommend ROW_NUMBER().
Here's a short and simple function for getting a single param:
function getUrlParam(paramName) {
var match = window.location.search.match("[?&]" + paramName + "(?:&|$|=([^&]*))");
return match ? (match[1] ? decodeURIComponent(match[1]) : "") : null;
}
The handling of these special cases are consistent with URLSearchParams:
If the parameter is missing, null
is returned.
If the parameter is present but there is no "=" (e.g. "?param"), ""
is returned.
Note! If there is a chance that the parameter name can contain special URL or regex characters (e.g. if it comes from user input) you need to escape it. This can easily be done like this:
function getUrlParamWithSpecialName(paramName) {
return getUrlParam(encodeURIComponent(paramName).replace(/[.*+?^${}()|[\]\\]/g, "\\$&"));
}
$fname = "database.php";
$fhandle = fopen($fname,"r");

$fhandle = fopen($fname,"w");
fwrite($fhandle,$content);
fclose($fhandle);
To add a foreign key (grade_id) to an existing table (users), follow the following steps:

If you want to read a file line by line and writing this in another:
var fs = require('fs');
var readline = require('readline');
var Stream = require('stream');
function readFileLineByLine(inputFile, outputFile) {
var instream = fs.createReadStream(inputFile);
var outstream = new Stream();
outstream.readable = true;
outstream.writable = true;
var rl = readline.createInterface({
input: instream,
output: outstream,
terminal: false
});
rl.on('line', function (line) {
fs.appendFileSync(outputFile, line + '\n');
});
};
dt = dt.AsEnumerable().GroupBy(r => r.Field<int>("ID")).Select(g => g.First()).CopyToDataTable();
Something like this:
JSONObject songs= json.getJSONObject("songs");
Iterator x = songs.keys();
JSONArray jsonArray = new JSONArray();
while (x.hasNext()){
String key = (String) x.next();
jsonArray.put(songs.get(key));
}
An easier way is to use ExecuteTime plugin in jupyter_contrib_nbextensions package.
pip install jupyter_contrib_nbextensions
jupyter contrib nbextension install --user
jupyter nbextension enable execute_time/ExecuteTime
To resolve by keeping the version in your current branch (ignore the version from the branch you are merging in), just add and commit the file:
git commit -a
To resolve by overwriting the version in your current branch with the version from the branch you are merging in, you need to retrieve that version into your working directory first, and then add/commit it:
git checkout otherbranch theconflictedfile
git commit -a
I faced the similar problem with intellij IDEA. you can use this
VelocityEngine ve = new VelocityEngine();
Properties props = new Properties();
props.put("file.resource.loader.path", "/Users/Projects/Comparator/src/main/resources/");
ve.init(props);
Template t = ve.getTemplate("helloworld.vm");
VelocityContext context = new VelocityContext();
#include <conio.h>
if (kbhit() != 0) {
cout << getch() << endl;
}
This uses kbhit()
to check if the keyboard is being pressed and uses getch()
to get the character that is being pressed.
When you concatenate strings, you need to allocate memory to store the result. The easiest to start with is String
and &str
:
fn main() {
let mut owned_string: String = "hello ".to_owned();
let borrowed_string: &str = "world";
owned_string.push_str(borrowed_string);
println!("{}", owned_string);
}
Here, we have an owned string that we can mutate. This is efficient as it potentially allows us to reuse the memory allocation. There's a similar case for String
and String
, as &String
can be dereferenced as &str
.
fn main() {
let mut owned_string: String = "hello ".to_owned();
let another_owned_string: String = "world".to_owned();
owned_string.push_str(&another_owned_string);
println!("{}", owned_string);
}
After this, another_owned_string
is untouched (note no mut
qualifier). There's another variant that consumes the String
but doesn't require it to be mutable. This is an implementation of the Add
trait that takes a String
as the left-hand side and a &str
as the right-hand side:
fn main() {
let owned_string: String = "hello ".to_owned();
let borrowed_string: &str = "world";
let new_owned_string = owned_string + borrowed_string;
println!("{}", new_owned_string);
}
Note that owned_string
is no longer accessible after the call to +
.
What if we wanted to produce a new string, leaving both untouched? The simplest way is to use format!
:
fn main() {
let borrowed_string: &str = "hello ";
let another_borrowed_string: &str = "world";
let together = format!("{}{}", borrowed_string, another_borrowed_string);
// After https://rust-lang.github.io/rfcs/2795-format-args-implicit-identifiers.html
// let together = format!("{borrowed_string}{another_borrowed_string}");
println!("{}", together);
}
Note that both input variables are immutable, so we know that they aren't touched. If we wanted to do the same thing for any combination of String
, we can use the fact that String
also can be formatted:
fn main() {
let owned_string: String = "hello ".to_owned();
let another_owned_string: String = "world".to_owned();
let together = format!("{}{}", owned_string, another_owned_string);
// After https://rust-lang.github.io/rfcs/2795-format-args-implicit-identifiers.html
// let together = format!("{owned_string}{another_owned_string}");
println!("{}", together);
}
You don't have to use format!
though. You can clone one string and append the other string to the new string:
fn main() {
let owned_string: String = "hello ".to_owned();
let borrowed_string: &str = "world";
let together = owned_string.clone() + borrowed_string;
println!("{}", together);
}
Note - all of the type specification I did is redundant - the compiler can infer all the types in play here. I added them simply to be clear to people new to Rust, as I expect this question to be popular with that group!
This may be a lazy man's solution, but can't you just delete the contents of the index you want removed by reassigning their values to 0 or "" and then ignore/skip these empty array elements instead of recreating and copying arrays on and off?
You can use the following code inside the style tag:
@media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {
/* IE10+ specific styles go here */
}
Below is an example that worked for me:
<style type="text/css">
@media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {
/* IE10+ specific styles go here */
#flashvideo {
width:320px;
height:240;
margin:-240px 0 0 350px;
float:left;
}
#googleMap {
width:320px;
height:240;
margin:-515px 0 0 350px;
float:left;
border-color:#000000;
}
}
#nav li {
list-style:none;
width:240px;
height:25px;
}
#nav a {
display:block;
text-indent:-5000px;
height:25px;
width:240px;
}
</style>
Please note that since (#nav li) and (#nav a) are outside of the @media screen ..., they are general styles.
I know this question is old, but it's got a lot of attention over the years and I think it's missing a concept which may help someone in a similar case. I'm adding it here for completeness sake.
If you cannot modify your original database schema, then a lot of good answers have been provided and solve the problem just fine.
If you can, however, modify your schema, I would advise to add a field in your customer
table that holds the id
of the latest customer_data
record for this customer:
CREATE TABLE customer (
id INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY,
current_data_id INT UNSIGNED NULL DEFAULT NULL
);
CREATE TABLE customer_data (
id INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY,
customer_id INT UNSIGNED NOT NULL,
title VARCHAR(10) NOT NULL,
forename VARCHAR(10) NOT NULL,
surname VARCHAR(10) NOT NULL
);
Querying is as easy and fast as it can be:
SELECT c.*, d.title, d.forename, d.surname
FROM customer c
INNER JOIN customer_data d on d.id = c.current_data_id
WHERE ...;
The drawback is the extra complexity when creating or updating a customer.
Whenever you want to update a customer, you insert a new record in the customer_data
table, and update the customer
record.
INSERT INTO customer_data (customer_id, title, forename, surname) VALUES(2, 'Mr', 'John', 'Smith');
UPDATE customer SET current_data_id = LAST_INSERT_ID() WHERE id = 2;
Creating a customer is just a matter of inserting the customer
entry, then running the same statements:
INSERT INTO customer () VALUES ();
SET @customer_id = LAST_INSERT_ID();
INSERT INTO customer_data (customer_id, title, forename, surname) VALUES(@customer_id, 'Mr', 'John', 'Smith');
UPDATE customer SET current_data_id = LAST_INSERT_ID() WHERE id = @customer_id;
The extra complexity for creating/updating a customer might be fearsome, but it can easily be automated with triggers.
Finally, if you're using an ORM, this can be really easy to manage. The ORM can take care of inserting the values, updating the ids, and joining the two tables automatically for you.
Here is how your mutable Customer
model would look like:
class Customer
{
private int id;
private CustomerData currentData;
public Customer(String title, String forename, String surname)
{
this.update(title, forename, surname);
}
public void update(String title, String forename, String surname)
{
this.currentData = new CustomerData(this, title, forename, surname);
}
public String getTitle()
{
return this.currentData.getTitle();
}
public String getForename()
{
return this.currentData.getForename();
}
public String getSurname()
{
return this.currentData.getSurname();
}
}
And your immutable CustomerData
model, that contains only getters:
class CustomerData
{
private int id;
private Customer customer;
private String title;
private String forename;
private String surname;
public CustomerData(Customer customer, String title, String forename, String surname)
{
this.customer = customer;
this.title = title;
this.forename = forename;
this.surname = surname;
}
public String getTitle()
{
return this.title;
}
public String getForename()
{
return this.forename;
}
public String getSurname()
{
return this.surname;
}
}

I had the same problem and the solution was to encapsulate the json inside this function
jsonp(
.... your json ...
)
You need to join
the two tables and then filter the result in where
clause:
SELECT country.name as country, country.headofstate
from country
inner join city on city.id = country.capital
where city.population > 100000
and country.headofstate like 'A%'
1-liner, takes a XML string text
and YourType
as the expected object type. not very different from other answers, just compressed to 1 line:
var result = (YourType)new XmlSerializer(typeof(YourType)).Deserialize(new StringReader(text));
In this case, if you really want to use ReadToEnd
method in MemoryStream
in an easy way, you can use this Extension Method to achieve this:
public static class SetExtensions
{
public static string ReadToEnd(this MemoryStream BASE)
{
BASE.Position = 0;
StreamReader R = new StreamReader(BASE);
return R.ReadToEnd();
}
}
And you can use this method in this way:
using (MemoryStream m = new MemoryStream())
{
//for example i want to serialize an object into MemoryStream
//I want to use XmlSeralizer
XmlSerializer xs = new XmlSerializer(_yourVariable.GetType());
xs.Serialize(m, _yourVariable);
//the easy way to use ReadToEnd method in MemoryStream
MessageBox.Show(m.ReadToEnd());
}

If you are using Kotlin and Kotlin android extensions, then there is a beautiful way of doing this.
val uri = myUriString.toUri()
To add Kotlin extensions (KTX) to your project add the following to your app module's build.gradle

This can be used to re-center the map to a specific location. Which is what I needed.
var MapBounds = new google.maps.LatLngBounds(
new google.maps.LatLng(35.676263, 13.949096),
new google.maps.LatLng(36.204391, 14.89038));
google.maps.event.addListener(GoogleMap, 'dragend', function ()
{
if (MapBounds.contains(GoogleMap.getCenter()))
{
return;
}
else
{
GoogleMap.setCenter(new google.maps.LatLng(35.920242, 14.428825));
}
});
A simple question should be followed by a short, simple and clear answer.
When we are getting a value of the property it fires its get{}
part.
When we are setting a value to the property it fires its set{}
part.
PS. When setting a value to the property, SWIFT automatically creates a constant named "newValue" = a value we are setting. After a constant "newValue" becomes accessible in the property's set{}
part.
Example:
var A:Int = 0
var B:Int = 0
var C:Int {
get {return 1}
set {print("Recived new value", newValue, " and stored into 'B' ")
B = newValue
}
}
//When we are getting a value of C it fires get{} part of C property
A = C
A //Now A = 1
//When we are setting a value to C it fires set{} part of C property
C = 2
B //Now B = 2
Removal invalidates only the iterators that point to the elements that are removed.
So in this case after removing *i , i is invalidated and you cannot do increment on it.
What you can do is first save the iterator of element that is to be removed , then increment the iterator and then remove the saved one.
The simplest way to do it is:
$(".modal-dialog").css("width", "80%");
where we can specify the width of the modal in terms of percentage of the screen.
Here is a working example to demonstrate the same:

On which point does HTTPURLConnection try to establish a connection to the given URL?
It's worth clarifying, there's the 'UrlConnection' instance and then there's the underlying Tcp/Ip/SSL socket connection, 2 different concepts. The 'UrlConnection' or 'HttpUrlConnection' instance is synonymous with a single HTTP page request, and is created when you call url.openConnection(). But if you do multiple url.openConnection()'s from the one 'url' instance then if you're lucky, they'll reuse the same Tcp/Ip socket and SSL handshaking stuff...which is good if you're doing lots of page requests to the same server, especially good if you're using SSL where the overhead of establishing the socket is very high.
To go the full manual route: This method converts doubles to strings by shifting the number's decimal point around and using floor (to long) and modulus to extract the digits. Also, it uses counting by base division to figure out the place where the decimal point belongs. It can also "delete" higher parts of the number once it reaches the places after the decimal point, to avoid losing precision with ultra-large doubles. See commented code at the end. In my testing, it is never less precise than the Java float representations themselves, when they actually show these imprecise lower decimal places.
/**
* Convert the given double to a full string representation, i.e. no scientific notation
* and always twelve digits after the decimal point.
* @param d The double to be converted
* @return A full string representation
*/
public static String fullDoubleToString(final double d) {
// treat 0 separately, it will cause problems on the below algorithm
if (d == 0) {
return "0.000000000000";
}
// find the number of digits above the decimal point
double testD = Math.abs(d);
int digitsBeforePoint = 0;
while (testD >= 1) {
// doesn't matter that this loses precision on the lower end
testD /= 10d;
++digitsBeforePoint;
}
// create the decimal digits
StringBuilder repr = new StringBuilder();
// 10^ exponent to determine divisor and current decimal place
int digitIndex = digitsBeforePoint;
double dabs = Math.abs(d);
while (digitIndex > 0) {
// Recieves digit at current power of ten (= place in decimal number)
long digit = (long)Math.floor(dabs / Math.pow(10, digitIndex-1)) % 10;
repr.append(digit);
--digitIndex;
}
// insert decimal point
if (digitIndex == 0) {
repr.append(".");
}
// remove any parts above the decimal point, they create accuracy problems
long digit = 0;
dabs -= (long)Math.floor(dabs);
// Because of inaccuracy, move to entirely new system of computing digits after decimal place.
while (digitIndex > -12) {
// Shift decimal point one step to the right
dabs *= 10d;
final var oldDigit = digit;
digit = (long)Math.floor(dabs) % 10;
repr.append(digit);
// This may avoid float inaccuracy at the very last decimal places.
// However, in practice, inaccuracy is still as high as even Java itself reports.
// dabs -= oldDigit * 10l;
--digitIndex;
}
return repr.insert(0, d < 0 ? "-" : "").toString();
}
Note that while StringBuilder is used for speed, this method can easily be rewritten to use arrays and therefore also work in other languages.
I'm not sure exactly what your problem is, because I cannot get your code to work as written. Two things seem evident:
Range
should be assigned to myRange
. Since a Range
type is an object in VBA it needs to be Set
, like this: Set myRange = Range("A:A")
CountA()
should be called with .WorksheetFunction
If you are not doing it already, consider using the Option Explicit option at the top of your module, and typing your variables with Dim
statements, as I have done below.
The following code works for me in 2010. Hopefully it works for you too:
Dim myRange As Range
Dim NumRows As Integer
Set myRange = Range("A:A")
NumRows = Application.WorksheetFunction.CountA(myRange)
Good Luck.
Like this:
people = []
begin
info = gets.chomp
people += [Person.new(info)] if not info.empty?
end while not info.empty?

Hi You can use a simple query,
select emp_cd, val1, val2, val3,
(val1+val2+val3) as total
from emp;
In case you need to insert a new row,
insert into emp select emp_cd, val1, val2, val3,
(val1+val2+val3) as total
from emp;
In order to update,
update emp set total = val1+val2+val3;
This will update for all comumns
Self-executing anonymous function. It's executed as soon as it is created.
One short and dummy example where this is useful is:
function prepareList(el){
var list = (function(){
var l = [];
for(var i = 0; i < 9; i++){
l.push(i);
}
return l;
})();
return function (el){
for(var i = 0, l = list.length; i < l; i++){
if(list[i] == el) return list[i];
}
return null;
};
}
var search = prepareList();
search(2);
search(3);
So instead of creating a list each time, you create it only once (less overhead).
In oracle db there is a trick for casting int to float (I suppose, it should also work in mysql):
select myintfield + 0.0 as myfloatfield from mytable
While @Heximal's answer works, I don't personally recommend it.
This is because it uses implicit casting. Although you didn't type CAST
, either the SUM()
or the 0.0
need to be cast to be the same data-types, before the +
can happen. In this case the order of precedence is in your favour, and you get a float on both sides, and a float as a result of the +
. But SUM(aFloatField) + 0
does not yield an INT, because the 0
is being implicitly cast to a FLOAT.
I find that in most programming cases, it is much preferable to be explicit. Don't leave things to chance, confusion, or interpretation.
If you want to be explicit, I would use the following.
CAST(SUM(sl.parts) AS FLOAT) * cp.price
-- using MySQL CAST FLOAT requires 8.0
You can try the following to see what happens...
CAST(SUM(sl.parts) AS NUMERIC(10,4)) * CAST(cp.price AS NUMERIC(10,4))
Actually I did it by uncommenting extension=php_curl.dll
in the xampp\apache\bin\php.ini file.
$('#fileupload').bind('change', function (e) { //dynamic property binding
alert('hello');// message you want to display
});
You can use this one also
In python 3
k = None
for name_of_the_group, group in dict(df_group):
if(k != name_of_the_group):
print ('\n', name_of_the_group)

print (group)
k = name_of_the_group

That's the XOR operator, not the PLUS operator
XOR works bit by bit, without carrying over like PLUS does
1 XOR 1 = 0
1 XOR 0 = 1
0 XOR 0 = 0
0 XOR 1 = 1
Yes: list1 + list2
. This gives a new list that is the concatenation of list1
and list2
.
If you are looking to execute a background process via PHP, pipe the command's output to /dev/null
and add &
to the end of the command.
exec("bg_process > /dev/null &");
Note that you can not utilize the $output
parameter of exec()
or else PHP will hang (probably until the process completes).
1.First open your terminal
2.Then update your gem file with command
sudo gem install -n /usr/local/bin cocoapods
3.Then give your project path
cd /your project path
4.Touch the podifle
touch podfile
5.Open your podfile
open -e podfile
6.It will open a podfile like a text edit. Then set your target. For example if you want to set up Google maps then your podfile should be like
use_frameworks!
target 'yourProjectName' do
pod 'GoogleMaps'
end
7.Then install the pod
pod install
You should add the httpRuntime

When you iterate through dictionaries using the for .. in ..
-syntax, it always iterates over the keys (the values are accessible using dictionary[key]
).
To iterate over key-value pairs, in Python 2 use for k,v in s.iteritems()
, and in Python 3 for k,v in s.items()
.
It's not possible to configure an IIS managed handler to run in classic mode. You should be running IIS in integrated mode if you want to do that.
You can learn more about modules, handlers and IIS modes in the following blog post:
IIS 7.0, ASP.NET, pipelines, modules, handlers, and preconditions
For handlers, if you set preCondition="integratedMode" in the mapping, the handler will only run in integrated mode. On the other hand, if you set preCondition="classicMode" the handler will only run in classic mode. And if you omit both of these, the handler can run in both modes, although this is not possible for a managed handler.
flex-box
The keys to this technique:
overflow: hidden
.justify-content: space-between
on the ul
(which is a flex-box) to force its flex-items to stretch to the left and right edges.margin-left: -1px
on the ul
to cause its left edge to overflow the container.border-left: 1px
on the li
flex-items.The container acts as a mask hiding the borders of any flex-items touching its left edge.
.flex-list {
position: relative;
margin: 1em;
overflow: hidden;
}
.flex-list ul {
display: flex;
flex-direction: row;
flex-wrap: wrap;
justify-content: space-between;
margin-left: -1px;
}
.flex-list li {
flex-grow: 1;

I think you're asking about a REPL (Read, Evaluate, Print, Loop) interface to perl. There are a few ways to do this:
Just add
<IfModule mod_headers.c>
Header set Access-Control-Allow-Origin "*"
</IfModule>
to the .htaccess
file in the root of the website you are trying to connect with.
Just as another option if you want to print only the key (doesn't write the .env file) you can use:
php artisan key:generate --show
.bashrc
is not sourced when you log in using SSH. You need to source it in your .bash_profile
like this:
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
In View:
<Button
Height="50" Width="50"
Style="{StaticResource MyButtonStyle}"
Command="{Binding SmallDisp}" CommandParameter="{Binding}"
Cursor="Hand" Visibility="{Binding Path=AdvancedFormat}"/>
In view Model:
public _advancedFormat = Visibility.visible (whatever you start with)
public Visibility AdvancedFormat
{
get{return _advancedFormat;}
set{
_advancedFormat = value;
//raise property changed here
}
You will need to have a property changed event
protected virtual void OnPropertyChanged(PropertyChangedEventArgs e)
{
PropertyChanged.Raise(this, e);
}
protected void OnPropertyChanged(string propertyName)
{
OnPropertyChanged(new PropertyChangedEventArgs(propertyName));
}
This is how they use Model-view-viewmodel
But since you want it binded to a boolean, You will need some converter. Another way is to set a boolean outside and when that button is clicked then set the property_advancedFormat to your desired visibility.
It's the first result on Google: http://docs.python.org/library/stdtypes.html#string-formatting
See also the new format() function: http://docs.python.org/library/stdtypes.html#str.format
I need to have a 32 bit JRE available for my browser, but 64 bit JRE for R and rJava. The 32 bit JRE is installed in the default location. After some experimentation, I found that I only needed one of misterbee's suggestions to get rJava (version 0.9-6) working for me. All I did was add the path to my 64 bit java installation:
C:\apps\Java\jre\bin\server\jvm.dll
to the top of my path environment variable (your path will likely be different) and remove my JAVA_HOME as user2161065 suggested. I put this just ahead of the entry
C:\ProgramData\Oracle\Java\javapath
which the Oracle installer inserts at the top of the path and points to some symlinks to the 32 bit JRE. By adding the entry to 64 bit jvm.dll, looks like rJava could find what it needs.
To use "conda activate" via Windows CMD, not the Anaconda Prompt:
(in response to okorng's question, although using the Anaconda Prompt is the preferred option)
First, we need to add the activate.bat script to your path:
Via CMD:
set PATH=%PATH%;<your_path_to_anaconda_installation>\Scripts
Or via Control Panel, open "User Accounts" and choose "Change my environment variables".
Then calling directly from Windows CMD:
activate <environment_name>
without using the prefix "conda".
(Tested on Windows 7 Enterprise with Anaconda3-5.2.0)
Based on the given answers and information in the question, this is the code you should use:
public static boolean doesURLExist(URL url) throws IOException
{
// We want to check the current URL
HttpURLConnection.setFollowRedirects(false);
HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
// We don't need to get data
httpURLConnection.setRequestMethod("HEAD");
// Some websites don't like programmatic access so pretend to be a browser
httpURLConnection.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2 (.NET CLR 3.5.30729)");
int responseCode = httpURLConnection.getResponseCode();
// We only accept response code 200
return responseCode == HttpURLConnection.HTTP_OK;
}
Of course tested and working.

Mozilla Developer Network has a nice description and example of onbeforeunload.
If you want to warn the user before leaving the page if your page is dirty (i.e. if user has entered some data):
window.addEventListener('beforeunload', function(e) {
var myPageIsDirty = ...; //you implement this logic...
if(myPageIsDirty) {
//following two lines will cause the browser to ask the user if they
//want to leave. The text of this dialog is controlled by the browser.
e.preventDefault(); //per the standard
e.returnValue = ''; //required for Chrome
}
//else: user is allowed to leave without a warning dialog
});
The format defined in RFC2617 is credentials = auth-scheme #auth-param
. So, in agreeing with fumanchu, I think the corrected authorization scheme would look like
Authorization: FIRE-TOKEN apikey="0PN5J17HBGZHT7JJ3X82", hash="frJIUN8DYpKDtOLCwo//yllqDzg="
Where FIRE-TOKEN
is the scheme and the two key-value pairs are the auth parameters. Though I believe the quotes are optional (from Apendix B of p7-auth-19)...
auth-param = token BWS "=" BWS ( token / quoted-string )
I believe this fits the latest standards, is already in use (see below), and provides a key-value format for simple extension (if you need additional parameters).
Some examples of this auth-param syntax can be seen here...

There are precious few immutable collections in the current framework. I can think of one relatively pain-free option in .NET 3.5:
Use Enumerable.ToLookup()
- the Lookup<,>
class is immutable (but multi-valued on the rhs); you can do this from a Dictionary<,>
quite easily:
Dictionary<string, int> ids = new Dictionary<string, int> {
{"abc",1}, {"def",2}, {"ghi",3}
};
ILookup<string, int> lookup = ids.ToLookup(x => x.Key, x => x.Value);
int i = lookup["def"].Single();
Actually, you do not need to do a first guess. Simply doing
import matplotlib.pyplot as plt
from scipy.optimize import curve_fit
from scipy import asarray as ar,exp
x = ar(range(10))
y = ar([0,1,2,3,4,5,4,3,2,1])
n = len(x) #the number of data
mean = sum(x*y)/n #note this correction
sigma = sum(y*(x-mean)**2)/n #note this correction
def gaus(x,a,x0,sigma):
return a*exp(-(x-x0)**2/(2*sigma**2))
popt,pcov = curve_fit(gaus,x,y)
#popt,pcov = curve_fit(gaus,x,y,p0=[1,mean,sigma])
plt.plot(x,y,'b+:',label='data')
plt.plot(x,gaus(x,*popt),'ro:',label='fit')
plt.legend()
plt.title('Fig. 3 - Fit for Time Constant')
plt.xlabel('Time (s)')
plt.ylabel('Voltage (V)')
plt.show()
works fine. This is simpler because making a guess is not trivial. I had more complex data and did not manage to do a proper first guess, but simply removing the first guess worked fine :)
P.S.: use numpy.exp() better, says a warning of scipy
It's best to use miske's answer.
If you really want to use natecarlson's repository, the instructions just below can do any of the following:
apt-get update
gives a 404
error after add-apt-repository
apt-get update
gives a NO_PUBKEY
error after manually adding it to /etc/apt/sources.list
Open a terminal and run the following:
sudo -i
Enter your password if necessary, then paste the following into the terminal:
export GOOD_RELEASE='precise'
export BAD_RELEASE="`lsb_release -cs`"
cd /etc/apt
sed -i '/natecarlson\/maven3/d' sources.list
cd sources.list.d
rm -f natecarlson-maven3-*.list*
apt-add-repository -y ppa:natecarlson/maven3
mv natecarlson-maven3-${BAD_RELEASE}.list natecarlson-maven3-${GOOD_RELEASE}.list
sed -i "s/${BAD_RELEASE}/${GOOD_RELEASE}/" natecarlson-maven3-${GOOD_RELEASE}.list
apt-get update
exit
echo Done!
If you installed natecarlson's repository (either using add-apt-repository

If your second font still doesn't work, make sure you're spelling its typeface name and its file name correctly, your browser caches are behaving, your OS isn't messing around with a font of the same name, etc.
localStorage
is something that is kept on the client side. There is no data transmitted to the server side.
You can only get the data with JavaScript and you can send it to the server side with Ajax.
There are two approaches: shmget
and mmap
. I'll talk about mmap
, since it's more modern and flexible, but you can take a look at man shmget
(or this tutorial) if you'd rather use the old-style tools.
The mmap()
function can be used to allocate memory buffers with highly customizable parameters to control access and permissions, and to back them with file-system storage if necessary.
The following function creates an in-memory buffer that a process can share with its children:
#include <stdio.h>
#include <stdlib.h>
#include <sys/mman.h>
void* create_shared_memory(size_t size) {
// Our memory buffer will be readable and writable:
int protection = PROT_READ | PROT_WRITE;
// The buffer will be shared (meaning other processes can access it), but
// anonymous (meaning third-party processes cannot obtain an address for it),
// so only this process and its children will be able to use it:
int visibility = MAP_SHARED | MAP_ANONYMOUS;
// The remaining parameters to `mmap()` are not important for this use case,
// but the manpage for `mmap` explains their purpose.
return mmap(NULL, size, protection, visibility, -1, 0);
}
The following is an example program that uses the function defined above to allocate a buffer. The parent process will write a message, fork, and then wait for its child to modify the buffer. Both processes can read and write the shared memory.
#include <string.h>
#include <unistd.h>
int main() {
char parent_message[] = "hello"; // parent process will write this message
char child_message[] = "goodbye"; // child process will then write this one
void* shmem = create_shared_memory(128);
memcpy(shmem, parent_message, sizeof(parent_message));
int pid = fork();
if (pid == 0) {
printf("Child read: %s\n", shmem);
memcpy(shmem, child_message, sizeof(child_message));
printf("Child wrote: %s\n", shmem);
} else {
printf("Parent read: %s\n", shmem);
sleep(1);
printf("After 1s, parent read: %s\n", shmem);
}
}
Your comparison function is not even wrong.
Its arguments should be the type stored in the range, i.e. std::pair<K,V>
, not const void*
.
It should return bool
not a positive or negative value. Both (bool)1
and (bool)-1
are true
so your function says every object is ordered before every other object, which is clearly impossible.
You need to model the less-than operator, not strcmp
or memcmp
style comparisons.
See StrictWeakOrdering which describes the properties the function must meet.
Your IDE might be pointing to a different installation of Python than where Selenium is installed.
I'm using Eclipse and when I ran 'quick auto-configure' under:
Preferences > PyDev > Interpreters > Python Interpreter
it pointed to a different version of Python than where pip or easy_install actually installed it.
Selenium worked from the Terminal so I determined which version of python my Terminal was using by running this:
python -c "import sys; print(sys.path)"
then had Eclipse point to that same location, which for me on my 10.11 Mac was here:
/Library/Frameworks/Python.framework/Versions/Current/bin/python2.7/
You can run "Advanced Auto-Config" as well to see all of the installed versions of python and select the one you want to use. When I selected that same location using "Advanced Auto-Config" it finally showed me the Selenium folder as it went through the configuration steps.
I had the same issue and while user1732055's answer fixes the border, it removes the dropdown arrows. I solved this by removing the border from the select
element and creating a wrapper span
which has a border.
html:
<span class="select-wrapper">
<select class="form-control no-radius">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
</span>
css:
select.no-radius{
border:none;
}
.select-wrapper{
border: 1px solid black;
border-radius: 0px;
}
Comparing two objects of the same type using LINQ and Reflection. NB! This is basically a rewrite of the solution from Jon Skeet, but with a more compact and modern syntax. It should also generate slightly more effecticve IL.
It goes something like this:
public bool ReflectiveEquals(LocalHdTicket serverTicket, LocalHdTicket localTicket)
{
if (serverTicket == null && localTicket == null) return true;
if (serverTicket == null || localTicket == null) return false;
var firstType = serverTicket.GetType();
// Handle type mismatch anyway you please:
if(localTicket.GetType() != firstType) throw new Exception("Trying to compare two different object types!");
return !(from propertyInfo in firstType.GetProperties()
where propertyInfo.CanRead
let serverValue = propertyInfo.GetValue(serverTicket, null)
let localValue = propertyInfo.GetValue(localTicket, null)
where !Equals(serverValue, localValue)
select serverValue).Any();
}
Aforementioned answers are great, just putting few points I see might be helpful:
Func is built-in delegate type
Func delegate type must return a value. Use Action delegate if no return type needed.
Func delegate type can have zero to 16 input parameters.
Func delegate does not allow ref and out parameters.
Func delegate type can be used with an anonymous method or lambda expression.
Func<int, int, int> Sum = (x, y) => x + y;
JavaScript is a scripting language and therefore stays in human readable form until it is time for it to be interpreted and executed by the JavaScript runtime.
The only way to partially hide it, at least from the less technical minds, is to obfuscate.
Obfuscation makes it harder for humans to read it, but not impossible for the technically savvy.
LinkedHashMap maintains the order of the keys.
java.util.LinkedHashMap appears to work just like a normal HashMap otherwise.
A simple way to get the ids of the checked check boxes by class name:
$(".yourClassName:checkbox:checked").each(function() {
console.log($(this).attr("id"));
});
The current answers are a bit out of date so, for clarity:
The short answer is:
This is documented on GitHub: duplicating-a-repository
I had the same problem, and turns out I had never completely compiled the fresh project. So right-clicking and selecting Compile'' (shift-cmd-F9 on mac) fixed it. It seems the compile on save does not 'see' non-compiled files.
Marking the src folder as source did not help in my case.
Another, less convenient, way to do it is to use Decimal
class:
from decimal import Decimal
pos_inf = Decimal('Infinity')
neg_inf = Decimal('-Infinity')
It really depends on what you want to do with that exception after you catch it. If you need to differentiate your exception then you have to create your custom Exception
. Otherwise you could just throw new Exception("message goes here");
This will inspect the docker image and print the layers:

The characters allowed in a URI are either reserved or unreserved (or a percent character as part of a percent-encoding)
http://en.wikipedia.org/wiki/Percent-encoding#Types_of_URI_characters
says these are RFC 3986 unreserved characters (sec. 2.3) as well as reserved characters (sec 2.2) if they need to retain their special meaning. And also a percent character as part of a percent-encoding.
I do a lot of logging where the timestamps are float64 and use this function to get the timestamps as string:
func dateFormat(layout string, d float64) string{
intTime := int64(d)
t := time.Unix(intTime, 0)
if layout == "" {
layout = "2006-01-02 15:04:05"
}
return t.Format(layout)
}
git log -n 1 [branch_name]
branch_name
(may be remote or local branch) is optional. Without branch_name
, it will show the latest commit on the current branch.
For example:
git log -n 1
git log -n 1 origin/master
git log -n 1 some_local_branch
git log -n 1 --pretty=format:"%H" #To get only hash value of commit
There is no difference between keystore and truststore files. Both are files in the proprietary JKS file format. The distinction is in the use: To the best of my knowledge, Java will only use the store that is referenced by the -Djavax.net.ssl.trustStore
system property to look for certificates to trust when creating SSL connections. Same for keys and -Djavax.net.ssl.keyStore
. But in theory it's fine to use one and the same file for trust- and keystores.
Here is another solution considering all columns (more compact way of J.J's answer);
ar=np.array([[0, 0, 0, 1],
[1, 0, 1, 0],
[0, 1, 0, 0],
[1, 0, 0, 1],
[0, 0, 1, 0],
[1, 1, 0, 0]])
Sort with lexsort,
ar[np.lexsort(([ar[:, i] for i in range(ar.shape[1]-1, -1, -1)]))]
Output:
array([[0, 0, 0, 1],
[0, 0, 1, 0],
[0, 1, 0, 0],
[1, 0, 0, 1],
[1, 0, 1, 0],
[1, 1, 0, 0]])
You can pass all similar type values in the function while calling it. In the function definition put a array so that all the passed values can be collected in that array. e.g. .
static void demo (String ... stringArray) {
your code goes here where read the array stringArray
}
And if you have more than one .css or .js file to call, just include them one after another, or:
<head>
<link href="css/grid.css" rel="stylesheet" />
<link href="css/style.css" rel="stylesheet" />
<script src="js/jquery-1.4.4.min.js"></script>
<script src="js/jquery.animate-colors-min.js"></script>
</head>
This is an alternative to pip. I also had the same error when installing scipy with pip.
Then I downloaded and installed MiniConda. And then I used the below command to install pytables.
conda install -c conda-forge scipy
Please refer the below screenshot.
Unfortunately, the best thing I have seen is the jquery.combobox, but it doesn't really look like something I'd really want to use in my web applications. I think there are some usability issues with this control, but as a user I don't think I'd know to start typing for the dropdownlist to turn into a textbox.
I much prefer the Combo Dropdown Box, but it still has some features that I'd want and it's still in alpha. The only think I don't like about this other than its being alpha... is that once I type in the combobox, the original dropdownlist items disappear. However, maybe there is a setting for this... or maybe it could be added fairly easily.
Those are the only two options that I know of. Good luck in your search. I'd love to hear if you find one or if the second option works out for you.
You may use:
To create array of objects:
var source = ['left', 'top'];
const result = source.map(arrValue => ({[arrValue]: 0}));
Demo:
var source = ['left', 'top'];_x000D_
_x000D_
const result = source.map(value => ({[value]: 0}));_x000D_
_x000D_
console.log(result);
_x000D_
Or if you wants to create a single object from values of arrays:
var source = ['left', 'top'];
const result = source.reduce((obj, arrValue) => (obj[arrValue] = 0, obj), {});
Demo:
var source = ['left', 'top'];_x000D_
_x000D_
const result = source.reduce((obj, arrValue) => (obj[arrValue] = 0, obj), {});_x000D_
_x000D_
console.log(result);
_x000D_
It seems that you have forgotten to add your state server address in the config file.
<sessionstate mode="StateServer" timeout="20" server="127.0.0.1" port="42424" />
Basically you can isolate your root application context and web application context using ContextLoaderListner.
The config file mapped with context param will behave as root application context configuration. And config file mapped with dispatcher servlet will behave like web application context.
In any web application we may have multiple dispatcher servlets, so multiple web application contexts.
But in any web application we may have only one root application context that is shared with all web application contexts.
We should define our common services, entities, aspects etc in root application context. And controllers, interceptors etc are in relevant web application context.
A sample web.xml is
<!-- language: xml -->
<web-app>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextClass</param-name>
<param-value>org.springframework.web.context.support.AnnotationConfigWebApplicationContext</param-value>
</context-param>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>example.config.AppConfig</param-value>
</context-param>
<servlet>
<servlet-name>restEntryPoint</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextClass</param-name>
<param-value>org.springframework.web.context.support.AnnotationConfigWebApplicationContext</param-value>
</init-param>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>example.config.RestConfig</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>restEntryPoint</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
<servlet>
<servlet-name>webEntryPoint</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextClass</param-name>
<param-value>org.springframework.web.context.support.AnnotationConfigWebApplicationContext</param-value>
</init-param>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>example.config.WebConfig</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>webEntryPoint</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
Here config class example.config.AppConfig can be used to configure services, entities, aspects etc in root application context that will be shared with all other web application contexts (for example here we have two web application context config classes RestConfig and WebConfig)
PS: Here ContextLoaderListener is completely optional. If we will not mention ContextLoaderListener in web.xml here, AppConfig will not work. In that case we need to configure all our services and entities in WebConfig and Rest Config.
Oracle Client version 11 cannot connect to 8i databases. You will need a client in version 10 at most.
First of all, since Spring doesn't do persistence itself, it cannot specify what readOnly
should exactly mean. This attribute is only a hint to the provider, the behavior depends on, in this case, Hibernate.
If you specify readOnly
as true
, the flush mode will be set as FlushMode.NEVER
in the current Hibernate Session preventing the session from committing the transaction.
Furthermore, setReadOnly(true) will be called on the JDBC Connection, which is also a hint to the underlying database. If your database supports it (most likely it does), this has basically the same effect as FlushMode.NEVER
, but it's stronger since you cannot even flush manually.
Now let's see how transaction propagation works.
If you don't explicitly set readOnly
to true
, you will have read/write transactions. Depending on the transaction attributes (like REQUIRES_NEW
), sometimes your transaction is suspended at some point, a new one is started and eventually committed, and after that the first transaction is resumed.
OK, we're almost there. Let's see what brings readOnly
into this scenario.
If a method in a read/write transaction calls a method that requires a readOnly transaction, the first one should be suspended, because otherwise a flush/commit would happen at the end of the second method.
Conversely, if you call a method from within a readOnly transaction that requires read/write, again, the first one will be suspended, since it cannot be flushed/committed, and the second method needs that.
In the readOnly-to-readOnly, and the read/write-to-read/write cases the outer transaction doesn't need to be suspended (unless you specify propagation otherwise, obviously).
JPA specification contains a very precise description of semantics of these operations, better than in javadoc:
The semantics of the persist operation, applied to an entity X are as follows:
If X is a new entity, it becomes managed. The entity X will be entered into the database at or before transaction commit or as a result of the flush operation.
If X is a preexisting managed entity, it is ignored by the persist operation. However, the persist operation is cascaded to entities referenced by X, if the relationships from X to these other entities are annotated with the
cascade=PERSIST
orcascade=ALL
annotation element value or specified with the equivalent XML descriptor element.If X is a removed entity, it becomes managed.
If X is a detached object, the
EntityExistsException
may be thrown when the persist operation is invoked, or theEntityExistsException
or anotherPersistenceException
may be thrown at flush or commit time.For all entities Y referenced by a relationship from X, if the relationship to Y has been annotated with the cascade element value
cascade=PERSIST
orcascade=ALL
, the persist operation is applied to Y.
The semantics of the merge operation applied to an entity X are as follows:
If X is a detached entity, the state of X is copied onto a pre-existing managed entity instance X' of the same identity or a new managed copy X' of X is created.
If X is a new entity instance, a new managed entity instance X' is created and the state of X is copied into the new managed entity instance X'.
If X is a removed entity instance, an
IllegalArgumentException
will be thrown by the merge operation (or the transaction commit will fail).If X is a managed entity, it is ignored by the merge operation, however, the merge operation is cascaded to entities referenced by relationships from X if these relationships have been annotated with the cascade element value
cascade=MERGE
orcascade=ALL
annotation.For all entities Y referenced by relationships from X having the cascade element value
cascade=MERGE
orcascade=ALL
, Y is merged recursively as Y'. For all such Y referenced by X, X' is set to reference Y'. (Note that if X is managed then X is the same object as X'.)If X is an entity merged to X', with a reference to another entity Y, where
cascade=MERGE
orcascade=ALL
is not specified, then navigation of the same association from X' yields a reference to a managed object Y' with the same persistent identity as Y.
Try placing the desired java directory in PATH before not needed java directories in your PATH.
if you need to keep only a few rows, consider
DELETE FROM tablename WHERE id NOT IN (5,124,221);
This will keep only some records and discard others.
I had a similar problem. The fontsquirel demo page was working in FF but not my own page even though all files were coming from the same domain!
It turned out that I was linking my stylesheet with an absolute URL (http://example.com/style.css) so FF thought it was coming from a different domain. Changing my stylesheet link href to /style.css instead fixed things for me.
A simple example:
import java.util.Scanner;
public class Example
{
public static void main(String[] args)
{
int number1, number2, sum;
Scanner input = new Scanner(System.in);
System.out.println("Enter First multiple");
number1 = input.nextInt();
System.out.println("Enter second multiple");
number2 = input.nextInt();
sum = number1 * number2;
System.out.printf("The product of both number is %d", sum);
}
}
Also check that your server isn't setting secure cookies on a non http request. Just found out that my ajax request was getting a php session with "secure" set. Because I was not on https it was not sending back the session cookie and my session was getting reset on each ajax request.
In iTerm -> Preferences -> Profiles Tab -> General section set Command to: /bin/zsh --login
I was having the same problem, the fact is that the input of lat and long should be String. Only then did I manage.
for example:
Controller.
ViewBag.Lat = object.Lat.ToString().Replace(",", ".");
ViewBag.Lng = object.Lng.ToString().Replace(",", ".");
View - function javascript
<script>
function initMap() {
var myLatLng = { lat: @ViewBag.Lat, lng: @ViewBag.Lng};
// Create a map object and specify the DOM element for display.
var map = new window.google.maps.Map(document.getElementById('map'),
{
center: myLatLng,
scrollwheel: false,
zoom: 16
});
// Create a marker and set its position.
var marker = new window.google.maps.Marker({
map: map,
position: myLatLng
//title: "Blue"
});
}
</script>
I convert the double value to string and do a Replace in the ',' to '.' And so everything works normally.
You could use this one as well with kramdown:
markdown
![drawing](drawing.jpg)
{:.some-css-class style="width: 200px"}
or
markdown
![drawing](drawing.jpg)
{:.some-css-class width="200"}
This way you can directly add arbitrary attributes to the last html element. To add classes there is a shortcut .class.secondclass.
Instead you will receive callback on onRequestPermissionsResult()
as PERMISSION_DENIED when you request permission again while falling in false condition of shouldShowRequestPermissionRationale()
From Android doc:
When the system asks the user to grant a permission, the user has the option of telling the system not to ask for that permission again. In that case, any time an app uses requestPermissions()
to ask for that permission again, the system immediately denies the request. The system calls your onRequestPermissionsResult()
callback method and passes PERMISSION_DENIED
, the same way it would if the user had explicitly rejected your request again. This means that when you call requestPermissions()
, you cannot assume that any direct interaction with the user has taken place.
Project ---> Clean does the trick in most of the cases. It did in mine.
It is good to write your own functions for conversions between numeral systems to learn something. For "real" code I would recommend to use build in conversion function from Python like bin(x), hex(x), int(x). Some examples can be found here.
The two query mechanism work in different ways, as suggested in the docs at the section Subdocuments:
When the field holds an embedded document (i.e, subdocument), you can either specify the entire subdocument as the value of a field, or “reach into” the subdocument using dot notation, to specify values for individual fields in the subdocument:
Equality matches within subdocuments select documents if the subdocument matches exactly the specified subdocument, including the field order.
In the following example, the query matches all documents where the value of the field producer is a subdocument that contains only the field company
with the value 'ABC123'
and the field address
with the value '123 Street'
, in the exact order:
db.inventory.find( {
producer: {
company: 'ABC123',
address: '123 Street'
}
});
print every line, like use Java BufferedReader read ervery line, and print it:
scala.io.Source.fromFile("test.txt" ).foreach{ print }
equivalent:
scala.io.Source.fromFile("test.txt" ).foreach( x => print(x))
