Image.fromarray -> returns an image object
from PIL import Image
import numpy as np
PIL_image = Image.fromarray(np.uint8(numpy_image)).convert('RGB')
PIL_image = Image.fromarray(numpy_image.astype('uint8'), 'RGB')
This is generally what the indexOf() method is for. You would say:
return arrValues.indexOf('Sam') > -1
You can use like this.
when: condition1 == "condition1" or condition2 == "condition2"

Try using Web API HttpClient
static async Task RunAsync()
{
using (var client = new HttpClient())
{
client.BaseAddress = new Uri("http://domain.com/");
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
// HTTP POST
var obj = new MyObject() { Str = "MyString"};
response = await client.PostAsJsonAsync("POST URL GOES HERE?", obj );
if (response.IsSuccessStatusCode)
{
response.//.. Contains the returned content.
}
}
}

You can also load the context while defining the servlet itself (WebApplicationContext)
<servlet>
<servlet-name>admin</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/spring/*.xml
</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>admin</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
rather than (ApplicationContext)
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext*.xml</param-value>
</context-param>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
or can do both together.
Drawback of just using WebApplicationContext is that it will load context only for this particular Spring entry point (DispatcherServlet
) where as with above mentioned methods context will be loaded for multiple entry points (Eg. Webservice Servlet, REST servlet
etc)
Context loaded by ContextLoaderListener
will infact be a parent context to that loaded specifically for DisplacherServlet . So basically you can load all your business service, data access or repository beans in application context and separate out your controller, view resolver beans to WebApplicationContext.
MySQL recommends using indexes for a variety of reasons including elimination of rows between conditions: http://dev.mysql.com/doc/refman/5.0/en/mysql-indexes.html
This makes your datetime column an excellent candidate for an index if you are going to be using it in conditions frequently in queries. If your only condition is BETWEEN NOW() AND DATE_ADD(NOW(), INTERVAL 30 DAY)
and you have no other index in the condition, MySQL will have to do a full table scan on every query. I'm not sure how many rows are generated in 30 days, but as long as it's less than about 1/3 of the total rows it will be more efficient to use an index on the column.
Your question about creating an efficient database is very broad. I'd say to just make sure that it's normalized and all appropriate columns are indexed (i.e. ones used in joins and where clauses).
For anyone who is looking for a solution to this problem in GitBook. This is how I made it work (in GitBook). You need to tag your header explicitly, like this:
# My Anchored Heading {#my-anchor}
Then link to this anchor like this
[link to my anchored heading](#my-anchor)
Solution, and additional examples, may be found here: https://seadude.gitbooks.io/learn-gitbook/
This will serve the purpose. There is no need for any divs or paragraph. If you want the spaces between them to be specified, use margin-left or margin-right in the css classes.

As often, numbers says more than feeling, here are some data: Pipe vs Unix Socket Performance (opendmx.net).
This benchmark shows a difference of about 12 to 15% faster speed for pipes.
Well here is a simple function which will return the left justified string version of an integer:
character(len=20) function str(k)
! "Convert an integer to string."
integer, intent(in) :: k
write (str, *) k
str = adjustl(str)
end function str
And here is a test code:
program x
integer :: i
do i=1, 100
open(11, file='Output'//trim(str(i))//'.txt')
write (11, *) i
close (11)
end do
end program x
The capitalization is wrong, and you have an extra argument.
Do this instead:
$('img#thumb').removeAttr('id');
For future reference, there aren't any jQuery methods that begin with a capital letter. They all take the same form as this one, starting with a lower case, and the first letter of each joined "word" is upper case.

We are already in 21st century!! Don't try to implement the already existing data structures. Try to use the existing data structures.
Use STL or Boost library
Every method needs to accept one argument: The instance itself (or the class if it is a static method).
Documentation can be found e.g. at MDN. Note that .split()
is not a jQuery method, but a native string method.
If you use .split()
on a string, then you get an array back with the substrings:
var str = 'something -- something_else';
var substr = str.split(' -- ');
// substr[0] contains "something"
// substr[1] contains "something_else"
If this value is in some field you could also do:
tRow.append($('<td>').text($('[id$=txtEntry2]').val().split(' -- ')[0])));
the following will do:
date -d "$(date +%Y-%m-1) -1 month" +%-m
date -d "$(date +%Y-%m-1) 0 month" +%-m
date -d "$(date +%Y-%m-1) 1 month" +%-m
or as you need:
LAST_MONTH=`date -d "$(date +%Y-%m-1) -1 month" +%-m`
NEXT_MONTH=`date -d "$(date +%Y-%m-1) 1 month" +%-m`
THIS_MONTH=`date -d "$(date +%Y-%m-1) 0 month" +%-m`
you asked for output like 9,10,11, so I used the %-m
%m
(without -) will produce output like 09,... (leading zero)
this also works for more/less than 12 months:
date -d "$(date +%Y-%m-1) -13 month" +%-m
just try
date -d "$(date +%Y-%m-1) -13 month"
to see full result

Here's what I used in Oracle SQL to see if someone was passing a correctly formatted phone number:
WHERE REPLACE(TRANSLATE('555-555-1212','0123456789-','00000000000'),'0','') IS NULL AND
LENGTH(REPLACE(TRANSLATE('555-555-1212','0123456789','0000000000'),'0','')) = 2
The first part checks to see if the phone number has only numbers and the hyphen and the second part checks to see that the phone number has only two hyphens.

Like Robert Nishihara mentioned, Apache Arrow makes this easy, specifically with the Plasma in-memory object store, which is what Ray is built on.
I made brain-plasma specifically for this reason - fast loading and reloading of big objects in a Flask app. It's a shared-memory object namespace for Apache Arrow-serializable objects, including pickle
'd bytestrings generated by pickle.dumps(...)
.
The key difference with Apache Ray and Plasma is that it keeps track of object IDs for you. Any processes or threads or programs that are running on locally can share the variables' values by calling the name from any Brain
object.
$ pip install brain-plasma
$ plasma_store -m 10000000 -s /tmp/plasma
from brain_plasma import Brain
brain = Brain(path='/tmp/plasma/)
brain['a'] = [1]*10000
brain['a']

MVC's anti-forgery support writes a unique value to an HTTP-only cookie and then the same value is written to the form. When the page is submitted, an error is raised if the cookie value doesn't match the form value.
It's important to note that the feature prevents cross site request forgeries. That is, a form from another site that posts to your site in an attempt to submit hidden content using an authenticated user's credentials. The attack involves tricking the logged in user into submitting a form, or by simply programmatically triggering a form when the page loads.
The feature doesn't prevent any other type of data forgery or tampering based attacks.
To use it, decorate the action method or controller with the ValidateAntiForgeryToken
attribute and place a call to @Html.AntiForgeryToken()
in the forms posting to the method.

Alternatively, if you want to specify expected parameters in action signature, but pass them as arbitrary GET
arguments. Use filters, for example:
Create a route without parameters:
$Route::get('/history', ['uses'=>'ExampleController@history']);
Specify action with two parameters and attach the filter:
class ExampleController extends BaseController
{
public function __construct($browser)
{
$this->beforeFilter('filterDates', array(
'only' => array('history')
));
}
public function history($fromDate, $toDate)
{
/* ... */
}
}
Filter that translates GET
into action's arguments :
Route::filter('filterDates', function($route, Request $request) {
$notSpecified = '_';
$fromDate = $request->get('fromDate', $notSpecified);
$toDate = $request->get('toDate', $notSpecified);
$route->setParameter('fromDate', $fromDate);
$route->setParameter('toDate', $toDate);
});

A man search like...
man git | grep pull | grep request
gives
git request-pull <start> <url> [<end>]
But, despite the name, it's not what you want. According to the docs:
Generate a request asking your upstream project to pull changes into their tree. The request, printed to the standard output, begins with the branch description, summarizes the changes and indicates from where they can be pulled.
@HolgerJust mentioned the github gem that does what you want:
sudo gem install gh
gh pull-request [user] [branch]
Others have mentioned the official hub
package by github:
sudo apt-get install hub
or
brew install hub
then
hub pull-request [-focp] [-b <BASE>] [-h <HEAD>]

Generator is a function that produces an iterator. Therefore, once you have iterator instance, use next() to fetch the next item from the iterator.
As an example, use next() function to fetch the first item, and later use for in
to process remaining items:
# create new instance of iterator by calling a generator function
items = generator_function()
# fetch and print first item
first = next(items)
print('first item:', first)
# process remaining items:
for item in items:
print('next item:', item)
The problem with this is that when the SQL engine goes to evaluate the expression, it checks the FROM portion to pull the proper tables, and then the WHERE portion to provide some base criteria, so it cannot properly evaluate a dynamic condition on which column to check against.
You can use a WHERE clause when you're checking the WHERE criteria in the predicate, such as
WHERE account_location = CASE @locationType
WHEN 'business' THEN 45
WHEN 'area' THEN 52
END
so in your particular case, you're going to need put the query into a stored procedure or create three separate queries.
I used custom DTO (interface) to map a native query to - the most flexible approach and refactoring-safe.
The problem I had with this - that surprisingly, the order of fields in the interface and the columns in the query matters. I got it working by ordering interface getters alphabetically and then ordering the columns in the query the same way.
I actually used pretty much the same code as you above. My service registration in the manifest is the following
<service android:name=".service.MyService" android:enabled="true">
<intent-filter android:label="@string/menuItemStartService" >
<action android:name="it.unibz.bluedroid.bluetooth.service.MY_SERVICE"/>
</intent-filter>
</service>
In the service class I created an according constant string identifying the service name like:
public class MyService extends ForeGroundService {
public static final String MY_SERVICE = "it.unibz.bluedroid.bluetooth.service.MY_SERVICE";
...
}
and from the according Activity I call it with
startService(new Intent(MyService.MY_SERVICE));
and stop it with
stopService(new Intent(MyService.MY_SERVICE));
It works perfectly. Try to check your configuration and if you don't find anything strange try to debug whether your stopService get's called properly.
I was wondering if it is possible to execute something like this using JDBC.
"SELECT FROM * TABLE;INSERT INTO TABLE;"
Yes it is possible. There are two ways, as far as I know. They are
Following examples demonstrate the above two possibilities.
Example 1: ( To allow multiple queries ):
While sending a connection request, you need to append a connection property allowMultiQueries=true
to the database url. This is additional connection property to those if already exists some, like autoReConnect=true
, etc.. Acceptable values for allowMultiQueries
property are true
, false
, yes
, and no
. Any other value is rejected at runtime with an SQLException
.
String dbUrl = "jdbc:mysql:///test?allowMultiQueries=true";
Unless such instruction is passed, an SQLException
is thrown.
You have to use execute( String sql )
or its other variants to fetch results of the query execution.
boolean hasMoreResultSets = stmt.execute( multiQuerySqlString );
To iterate through and process results you require following steps:
READING_QUERY_RESULTS: // label
while ( hasMoreResultSets || stmt.getUpdateCount() != -1 ) {
if ( hasMoreResultSets ) {
Resultset rs = stmt.getResultSet();
// handle your rs here
} // if has rs
else { // if ddl/dml/...
int queryResult = stmt.getUpdateCount();
if ( queryResult == -1 ) { // no more queries processed
break READING_QUERY_RESULTS;
} // no more queries processed
// handle success, failure, generated keys, etc here
} // if ddl/dml/...
// check to continue in the loop
hasMoreResultSets = stmt.getMoreResults();
} // while results
Example 2: Steps to follow:
select
, and DML
queries.CallableStatement
.ResultSet
s executed in procedure.select
Sample table and procedure:
mysql> create table tbl_mq( i int not null auto_increment, name varchar(10), primary key (i) );
Query OK, 0 rows affected (0.16 sec)
mysql> delimiter //
mysql> create procedure multi_query()
-> begin
-> select count(*) as name_count from tbl_mq;
-> insert into tbl_mq( names ) values ( 'ravi' );
-> select last_insert_id();
-> select * from tbl_mq;
-> end;
-> //
Query OK, 0 rows affected (0.02 sec)
mysql> delimiter ;
mysql> call multi_query();
+------------+
| name_count |
+------------+
| 0 |
+------------+
1 row in set (0.00 sec)
+------------------+
| last_insert_id() |
+------------------+
| 3 |
+------------------+
1 row in set (0.00 sec)
+---+------+
| i | name |
+---+------+
| 1 | ravi |
+---+------+
1 row in set (0.00 sec)
Query OK, 0 rows affected (0.00 sec)
Call Procedure from Java:
CallableStatement cstmt = con.prepareCall( "call multi_query()" );
boolean hasMoreResultSets = cstmt.execute();
READING_QUERY_RESULTS:
while ( hasMoreResultSets ) {
Resultset rs = stmt.getResultSet();
// handle your rs here
} // while has more rs
You shouldn't use ForEach
in that way. Read Lippert's “foreach” vs “ForEach”
If you want to be cruel with yourself (and the world), at least don't create useless List
employees.All(p => {
collection.AddRange(p.Departments);
p.Departments.All(u => { u.SomeProperty = null; return true; } );
return true;
});
Note that the result of the All
expression is a bool
value that we are discarding (we are using it only because it "cycles" all the elements)
I'll repeat. You shouldn't use ForEach
to change objects. LINQ should be used in a "functional" way (you can create new objects but you can't change old objects nor you can create side-effects). And what you are writing is creating so many useless List
only to gain two lines of code...
If the this
value you want is the just the object that you bound the event handler to, then addEventListener()
already does that for you. When you do this:
productLineSelect.addEventListener('change', getSelection, false);
the getSelection
function will already be called with this
set to the object that the event handler was bound to. It will also be passed an argument that represents the event object which has all sorts of object information about the event.
function getSelection(event) {
// this will be set to the object that the event handler was bound to
// event is all the detailed information about the event
}
If the desired this
value is some other value than the object you bound the event handler to, you can just do this:
var self = this;
productLineSelect.addEventListener('change',function() {
getSelection(self)
},false);
By way of explanation:
this
into a local variable in your other event handler.this

MyInt(int val) : value(val) {}
auto operator<=>(const MyInt& other) const = default;

MyInt Six(6);
std::vector V{Five, Two, Six};
std::sort(V.begin(), V.end());

2018 - Revisiting this question with the latest Bootstrap 4.
The responsive ordering classes are now order-first
, order-last
and order-0
- order-12
The Bootstrap 4 push pull classes are now (This only works pre 4.0 beta)push-{viewport}-{units}
and pull-{viewport}-{units}
and the xs-
infix has been removed. To get the desired 1-3-2 layout on mobile/xs would be: Bootstrap 4 push pull demo
Bootstrap 4.1+
Since Bootstrap 4 is flexbox, it's easy to change the order of columns. The cols can be ordered from order-1
to order-12
, responsively such as order-md-12 order-2
(last on md
, 2nd on xs
) relative to the parent .row
.
<div class="container">
<div class="row">
<div class="col-3 col-md-6">
<div class="card card-body">1</div>

For easy copying of the code created repository
These are what's known as Shadow Copy Folders.
Simplistically....and I really mean it:
When ASP.NET runs your app for the first time, it copies any assemblies found in the /bin folder, copies any source code files (found for example in the App_Code folder) and parses your aspx, ascx files to c# source files. ASP.NET then builds/compiles all this code into a runnable application.
One advantage of doing this is that it prevents the possibility of .NET assembly DLL's #(in the /bin folder) becoming locked by the ASP.NET worker process and thus not updatable.
ASP.NET watches for file changes in your website and will if necessary begin the whole process all over again.
Theoretically the folder shouldn't need any maintenance, but from time to time, and only very rarely you may need to delete contents. That said, I work for a hosting company, we run up to 1200 sites per shared server and I haven't had to touch this folder on any of the 250 or so machines for years.

Did you try
$(this).val('test');
instead of
$(this).attr('value', 'test');
val()
is generally easier, since the attribute you need to change may be different on different DOM elements.
You can get the value from collection using for-each loop or using iterator interface. For a Collection c

System.out.println(elem);
or Using Iterator Interface
Iterator it = c.iterator();

object and an active (or inactive) ErrorHandler
. Both need to be handled and reset for new errors.

Just call fig.tight_layout()
as you normally would. (pyplot
is just a convenience wrapper. In most cases, you only use it to quickly generate figure and axes objects and then call their methods directly.)
There shouldn't be a difference between the QtAgg
backend and the default backend (or if there is, it's a bug).
E.g.
import matplotlib.pyplot as plt
#-- In your case, you'd do something more like:
# from matplotlib.figure import Figure
# fig = Figure()
#-- ...but we want to use it interactive for a quick example, so
#-- we'll do it this way
fig, axes = plt.subplots(nrows=4, ncols=4)
for i, ax in enumerate(axes.flat, start=1):
ax.set_title('Test Axes {}'.format(i))
ax.set_xlabel('X axis')
ax.set_ylabel('Y axis')
plt.show()
import matplotlib.pyplot as plt
fig, axes = plt.subplots(nrows=4, ncols=4)
for i, ax in enumerate(axes.flat, start=1):
ax.set_title('Test Axes {}'.format(i))
ax.set_xlabel('X axis')
ax.set_ylabel('Y axis')
fig.tight_layout()
plt.show()
Also note the CultureInformation of your system. Here my solution without rounding.
In this example you just have to define the variable MyValue as double. As result you get your formatted value in the string variable NewValue.
Note - Also set the C# using statement:
using System.Globalization;
string MyFormat = "0";
if (MyValue.ToString (CultureInfo.InvariantCulture).Contains (CultureInfo.InvariantCulture.NumberFormat.NumberDecimalSeparator))
{
MyFormat += ".00";
}
string NewValue = MyValue.ToString(MyFormat);
Use request.args
to get parsed contents of query string:
from flask import request
@app.route(...)
def login():
username = request.args.get('username')
password = request.args.get('password')
In this case, as snarly suggested, typing q is the intended way to quit git log
(as with most other pagers or applications that use pagers).
However normally, if you just want to abort a command that is currently executing, you can try ctrl+c (doesn't seem to work for git log
, however) or ctrl+z (although in bash, ctrl-z will freeze the currently running foreground process, which can then be thawed as a background process with the bg
command).
To use alternate credentials for a single operation, use the --username
and --password
switches for svn
.
To clear previously-saved credentials, delete ~/.subversion/auth
. You'll be prompted for credentials the next time they're needed.
These settings are saved in the user's home directory, so if you're using a shared account on "this laptop", be careful - if you allow the client to save your credentials, someone can impersonate you. The first option I provided is the better way to go in this case. At least until you stop using shared accounts on computers, which you shouldn't be doing.
To change credentials you need to do:
rm -rf ~/.subversion/auth
svn up
( it'll ask you for new username & password )Just try the code below:
As I see you have inserted 'r+' or this command open the file in read mode so you are not able to write into it, so you have to open file in write mode 'w' if you want to overwrite the file contents and write new data, otherwise you can append data to file by using 'a'
I hope this will help ;)
f = open('testfile.txt', 'w')# just put 'w' if you want to write to the file
x = f.readlines() #this command will read file lines
y = int(x)+1
print y
z = str(y) #making data as string to avoid buffer error
f.write(z)
f.close()
Depends how much you like the linq query syntax, you can use the extension methods directly like:
var item = Items.First(i => i.Id == 123);
And if you don't want to throw an error if the list is empty, use FirstOrDefault
which returns the default value for the element type (null
for reference types):
var item = Items.FirstOrDefault(i => i.Id == 123);
if (item != null)
{
// found it
}
Single()
and SingleOrDefault()
can also be used, but if you are reading from a database or something that already guarantees uniqueness I wouldn't bother as it has to scan the list to see if there's any duplicates and throws. First()
and FirstOrDefault()
stop on the first match, so they are more efficient.
Of the First()
and Single()
family, here's where they throw:
First()
- throws if empty/not found, does not throw if duplicateFirstOrDefault()
- returns default if empty/not found, does not throw if duplicateSingle()
- throws if empty/not found, throws if duplicate existsSingleOrDefault()
- returns default if empty/not found, throws if duplicate existsQuick one in TSQL

Enable "Show All Files" for the specific project (you might need to hit "Refresh" to see them)**.
The folders/files that are not part of your project appear slightly "lighter" in the project tree.
Right click the folders/files you want to add and click "Include In Project". It will recursively add folders/files to the project.
** These buttons are located on the mini Solution Explorer toolbar.
** Make sure you are NOT in debug mode.

stderr is usually unbuffered and stdout usually is. This can lead to odd looking output like this, which suggests code is executing in the wrong order. It isn't, it's just that the stdout buffer has yet to be flushed. Redirected or piped streams would of course not see this interleave as they would normally only see the output of stdout only or stderr only.
Although initially both stdout and stderr come to the console, both are separate and can be individually redirected.
Main problem with "This application is modifying the autolayout engine from a background thread" is that it seem to be logged a long time after the actual problem occurs, this can make it very hard to troubleshoot.
I managed to solve the issue by creating three symbolic breakpoints.
Debug > Breakpoints > Create Symbolic Breakpoint...
Breakpoint 1:
Symbol: -[UIView setNeedsLayout]
Condition: !(BOOL)[NSThread isMainThread]
Breakpoint 2:
Symbol: -[UIView layoutIfNeeded]
Condition: !(BOOL)[NSThread isMainThread]
Breakpoint 3:
Symbol: -[UIView updateConstraintsIfNeeded]
Condition: !(BOOL)[NSThread isMainThread]
With these breakpoints, you can easily get a break on the actual line where you incorrectly call UI methods on non-main thread.
In 1.0, the functionality was bound to (
and tab
and shift-tab
, in 2.0 tab
was deprecated but still functional in some unambiguous cases completing or inspecting were competing in many cases. Recommendation was to always use shift-Tab
. (
was also added as deprecated as confusing in Haskell-like syntax to also push people toward Shift-Tab as it works in more cases. in 3.0 the deprecated bindings have been remove in favor of the official, present for 18+ month now Shift-Tab
.
So press Shift-Tab
.

Strings in Python are immutable meaning you cannot replace parts of them.
You can however create a new string that is modified. Mind that this is not semantically equivalent since other references to the old string will not be updated.
You could for instance write a function:
def replace_str_index(text,index=0,replacement=''):
return '%s%s%s'%(text[:index],replacement,text[index+1:])
And then for instance call it with:
new_string = replace_str_index(old_string,middle)
If you do not feed a replacement, the new string will not contain the character you want to remove, you can feed it a string of arbitrary length.
For instance:
replace_str_index('hello?bye',5)
will return 'hellobye'
; and:
replace_str_index('hello?bye',5,'good')
will return 'hellogoodbye'
.
var countries = ['United States', 'Canada', 'Argentina', 'Armenia'];
var cList = $('ul.mylist')
$.each(countries, function(i) {
var li = $('<li/>')

.appendTo(cList);
var a = $('<a/>')
.addClass('ui-all')
.text( this )
.appendTo(li);
});
In python, this concatenates with blank lines between files (the ,
suppresses adding an extra trailing blank line):
print '\n'.join(open(f).read() for f in filenames),
Here is the ugly python one-liner that can be called from the shell and prints the output to a file:
python -c "from sys import argv; print '\n'.join(open(f).read() for f in argv[1:])," File*.txt > finalfile.txt
Just return the following:

In the event the method you're calling is private, or called from one location, try
return new Object[]{value1, value2};
The caller looks like:
Object[] temp=myMethod(parameters);
Type1 value1=(Type1)temp[0]; //For code clarity: temp[0] is not descriptive
Type2 value2=(Type2)temp[1];
The Pair example by David Hanak has no syntactic benefit, and is limited to two values.
return new Pair<Type1,Type2>(value1, value2);
And the caller looks like:
Pair<Type1, Type2> temp=myMethod(parameters);
Type1 value1=temp.a; //For code clarity: temp.a is not descriptive
Type2 value2=temp.b;
Type punning via pointer casts (as opposed to using a union) is a major example of breaking strict aliasing.
I solved my problem by adding just ${pageContext.request.contextPath} to my jsp path . in stead of :
<script src="static/js/jquery-3.2.1.min.js"></script>
I set :
<script src="${pageContext.request.contextPath}/static/js/jquery-3.2.1.min.js"></script>
Use sys.getsizeof
to get the size of an object, in bytes.
>>> from sys import getsizeof
>>> a = 42
>>> getsizeof(a)
12
>>> a = 2**1000
>>> getsizeof(a)
146
>>>
Note that the size and layout of an object is purely implementation-specific. CPython, for example, may use totally different internal data structures than IronPython. So the size of an object may vary from implementation to implementation.
There are three options:
>>> 4 / float(100)
0.04
>>> 4 / 100.0
0.04
which is the same behavior as the C, C++, Java etc, or
>>> from __future__ import division
>>> 4 / 100
0.04
You can also activate this behavior by passing the argument -Qnew
to the Python interpreter:
$ python -Qnew
>>> 4 / 100
0.04
The second option will be the default in Python 3.0. If you want to have the old integer division, you have to use the //
operator.
Edit: added section about -Qnew
, thanks to ??O?????!
This may also occur if your using slots in class and have not added this new attribute in slots yet.
class xyz(object):
"""
class description
"""
__slots__ = ['abc', 'ijk']
def __init__(self):
self.abc = 1
self.ijk = 2
self.pqr = 6 # This will throw error 'AttributeError: <name_of_class_object> object has no attribute 'pqr'
Linux does not have any system variables that give the current CPU utilization. Instead, you have to read /proc/stat
several times: each column in the cpu(n)
lines gives the total CPU time, and you have to take subsequent readings of it to get percentages. See this document to find out what the various columns mean.
The extensions methods also provide a ToDictionary extension. It is fairly simple to use, the general usage is passing a lambda selector for the key and getting the object as the value, but you can pass a lambda selector for both key and value.
class SomeObject
{
public int ID { get; set; }
public string Name { get; set; }
}
SomeObject[] objects = new SomeObject[]
{
new SomeObject { ID = 1, Name = "Hello" },
new SomeObject { ID = 2, Name = "World" }
};
Dictionary<int, string> objectDictionary = objects.ToDictionary(o => o.ID, o => o.Name);
Then objectDictionary[1]
Would contain the value "Hello"
If you have fixed the conflicts you need to add the files to the stage with git add [filename]
, then commit as normal.
I converted the VB code in the blog post linked by xsl to C# and modified it a bit:
public static bool TryGetRegisteredApplication(
string extension, out string registeredApp)
{
string extensionId = GetClassesRootKeyDefaultValue(extension);
if (extensionId == null)
{
registeredApp = null;
return false;
}
string openCommand = GetClassesRootKeyDefaultValue(
Path.Combine(new[] {extensionId, "shell", "open", "command"}));
if (openCommand == null)
{
registeredApp = null;
return false;
}
registeredApp = openCommand
.Replace("%1", string.Empty)
.Replace("\"", string.Empty)
.Trim();
return true;
}
private static string GetClassesRootKeyDefaultValue(string keyPath)
{
using (var key = Registry.ClassesRoot.OpenSubKey(keyPath))
{
if (key == null)
{
return null;
}
var defaultValue = key.GetValue(null);
if (defaultValue == null)
{
return null;
}
return defaultValue.ToString();
}
}

In 2019 with CSS3 you can do this without Javascript at all. I frequently make sticky headers like this:

}_x000D_
_x000D_
header {_x000D_

top: 0; /* specifies the start position for the sticky behavior - 0 is pretty common */_x000D_

Check my sample solution
<h5 style="float: left; width: 50%;">Employee: Employee Name</h5>
<h5 style="float: right; width: 50%; text-align: right;">Employee: Employee Name</h5>
This will divide your page into two and insert the two header elements to the right and left part equally.
It is possible with EditorConfig.
EditorConfig helps developers define and maintain consistent coding styles between different editors and IDEs.
This also includes file encoding.
EditorConfig is built-in Visual Studio 2017 by default, and I there were plugins available for versions as old as VS2012. Read more from EditorConfig Visual Studio Plugin page.
You can set up a EditorConfig configuration file high enough in your folder structure to span all your intended repos (up to your drive root should your files be really scattered everywhere) and configure the setting charset
:
charset: set to latin1, utf-8, utf-8-bom, utf-16be or utf-16le to control the character set.
You can add filters and exceptions etc on every folder level or by file name/type should you wish for finer control.
Once configured then compatible IDEs should automatically do it's thing to make matching files comform to set rules. Note that Visual Studio does not automatically convert all your files but do its bit when you work with files in IDE (open and save).
While you could have a Visual-studio-wide setup, I strongly suggest to still include an EditorConfig root to your solution version control, so that explicit settings are automatically synced to all team members as well. Your drive root editorconfig file can be the fallback should some project not have their own editorconfig files set up yet.
I've been using something like this. Just set up a simple HTML page with an textinput. Make sure that the textinput always has focus. When you scan a barcode with your barcode scanner you will receive the code and after that a 'enter'. Realy simple then; just capture the incoming keystrokes and when the 'enter' comes in you can use AJAX to handle your code.
Example here.
Pasted below:
This is about how to launch android application from the adb shell.
Command: am
Look for invoking path in AndroidManifest.xml
Browser app::
# am start -a android.intent.action.MAIN -n com.android.browser/.BrowserActivity
Starting: Intent { action=android.intent.action.MAIN comp={com.android.browser/com.android.browser.BrowserActivity} }
Warning: Activity not started, its current task has been brought to the front
Settings app::
# am start -a android.intent.action.MAIN -n com.android.settings/.Settings
Starting: Intent { action=android.intent.action.MAIN comp={com.android.settings/com.android.settings.Settings} }
Using forEach we can store data in case we have already data we want to do some business login on data.
var sample = new Array();
var x = 10;
var sample = [1,2,3,4,5,6,7,8,9];
var data = [];
sample.forEach(function(item){
data.push(item);
})
document.write(data);
Example by using simple for loop
var data = [];
for(var i = 0 ; i < 10 ; i++){
data.push(i);
}
document.write(data);
I just wrote a blog post on saving an object's data to Binary, XML, or Json. It sounds like you probably want to use Binary serialization, but perhaps you want the files to be edited outside of your app, in which case XML or Json might be better. Here are the functions to do it in the various formats. See my blog post for more details.

The "play" button is specifically for build and run (or test or profile, etc). The Archive action is intended to build for release and to generate an archive that is suitable for submission to the app store. If you want to skip that, you can choose Product > Build For > Archive to force the release build without actually archiving. To find the built product, expand the Products group in the Project navigator, right-click the product and choose to show in Finder.
That said, you can click and hold the play button for a menu of other build actions (including Build and Archive).
Here's a one liner (yes, it is similar to user333700's, but a little more straightforward):
>>> import numpy as np
>>> arr = np.array([[ 0.96488889, 0.73641667, 0.67521429, 0.592875, 0.53172222],
[ 0.78008333, 0.5938125, 0.481, 0.39883333, 0.]])
>>> print arr[arr.all(1)]
array([[ 0.96488889, 0.73641667, 0.67521429, 0.592875 , 0.53172222]])
By the way, this method is much, much faster than the masked array method for large matrices. For a 2048 x 5 matrix, this method is about 1000x faster.
By the way, user333700's method (from his comment) was slightly faster in my tests, though it boggles my mind why.
For others, if you want to find another process of the same executable, you can use:
public bool tryFindAnotherInstance(out Process process) {
Process thisProcess = Process.GetCurrentProcess();
string thisFilename = thisProcess.MainModule.FileName;
int thisPId = thisProcess.Id;
foreach (Process p in Process.GetProcesses())
{
try
{
if (p.MainModule.FileName == thisFilename && thisPId != p.Id)
{
process = p;
return true;
}
}
catch (Exception)
{
}
}
process = default;
return false;
}
What I did in the end is make a batch file to extract the CLASSPATH from the ant file, then run java directly using this:
In my build.xml:
<target name="printclasspath">
<pathconvert property="classpathProp" refid="project.class.path"/>
<echo>${classpathProp}</echo>
</target>
In another script called 'run.sh':
export CLASSPATH=$(ant -q printclasspath | grep echo | cut -d \ -f 7):build
java "$@"
It's no longer cross-platform, but at least it's relatively easy to use, and one could provide a .bat file that does the same as the run.sh. It's a very short batch script. It's not like migrating the entire build to platform-specific batch files.
I think it's a shame there's not some option in ant whereby you could do something like:
ant -- arg1 arg2 arg3
mpirun uses this type of syntax; ssh also can use this syntax I think.
[^\(]*(\(.*\))[^\)]*
[^\(]*
matches everything that isn't an opening bracket at the beginning of the string, (\(.*\))
captures the required substring enclosed in brackets, and [^\)]*
matches everything that isn't a closing bracket at the end of the string. Note that this expression does not attempt to match brackets; a simple parser (see dehmann's answer) would be more suitable for that.
You can make the following sql query
IF ((SELECT COUNT(*) FROM table1 WHERE project = 1) > 0)
SELECT product, price FROM table1 WHERE project = 1
ELSE IF ((SELECT COUNT(*) FROM table1 WHERE project = 2) > 0)
SELECT product, price FROM table1 WHERE project = 2
ELSE IF ((SELECT COUNT(*) FROM table1 WHERE project = 3) > 0)
SELECT product, price FROM table1 WHERE project = 3
After a long time suffering from it in PHPunit...
For those using namespace, which is very common with Frameworks or CMS, a good check in addition to seeing if php-xml is installed and active, is to remember to declare the DOMDocument after the namespace:
namespace YourNameSpace\YourNameSpace;
use DOMDocument; //<--- here, check this!
I would use a hashtable with in key takes the element of the array (here string) and in value an Integer.
then go through the list doing something like this :
for(String s:array){
if(hash.containsKey(s)){
Integer i = hash.get(s);
i++;
}else{
hash.put(s, new Interger(1));
}

You need to use a regular expression, so that you can specify the global (g) flag:
var s = 'some+multi+word+string'.replace(/\+/g, ' ');
(I removed the $()
around the string, as replace
is not a jQuery method, so that won't work at all.)
The appref-ms file does not point to the exe. When you hit that shortcut, it invokes the deployment manifest at the deployment provider url and checks for updates. It checks the application manifest (yourapp.exe.manifest) to see what files to download, and this file contains the definition of the entry point (i.e. the exe).
Yes, cmake and make are different programs. cmake

In theory everything is possible but reality you find the numbers much lower than you might expect. I have been trying to address huge spaces on servers often and found that even though a server can have huge amounts of memory it surprised me that most software actually never can address it in real scenario's simply because the cpu's are not fast enough to really address them. Why would you say right ?! . Timings thats the endless downfall of every enormous machine which i have worked on. So i would advise to not go overboard by addressing huge amounts just because you can, but use what you think could be used. Actual values are often much lower than what you expected. Ofcourse non of us really uses hp 9000 systems at home and most of you actually ever will go near the capacity of your home system ever. For instance most users do not have more than 16 Gb of memory in their system. Ofcourse some of the casual gamers use work stations for a game once a month but i bet that is a very small percentage. So coming down to earth means i would address on a 8 Gb 64 bit system not much more than 512 mb for heapspace or if you go overboard try 1 Gb. I am pretty sure its even with these numbers pure overkill. I have constant monitored the memory usage during gaming to see if the addressing would make any difference but did not notice any difference at all when i addressed much lower values or larger ones. Even on the server/workstations there was no visible change in performance no matter how large i set the values. That does not say some jave users might be able to make use of more space addressed, but this far i have not seen any of the applications needing so much ever. Ofcourse i assume that their would be a small difference in performance if java instances would run out of enough heapspace to work with. This far i have not found any of it at all, however lack of real installed memory showed instant drops of performance if you set too much heapspace. When you have a 4 Gb system you run quickly out of heapspace and then you will see some errors and slowdowns because people address too much space which actually is not free in the system so the os starts to address drive space to make up for the shortage hence it starts to swap.

In Python, what is the purpose of
__slots__
and what are the cases one should avoid this?
The special attribute __slots__
allows you to explicitly state which instance attributes you expect your object instances to have, with the expected results:
The space savings is from
__dict__
.__dict__
and __weakref__
creation if parent classes deny them and you declare __slots__
.Small caveat, you should only declare a particular slot one time in an inheritance tree. For example:
class Base:
__slots__ = 'foo', 'bar'
class Right(Base):
__slots__ = 'baz',
class Wrong(Base):
__slots__ = 'foo', 'bar', 'baz' # redundant foo and bar
Python doesn't object when you get this wrong (it probably should), problems might not otherwise manifest, but your objects will take up more space than they otherwise should. Python 3.8:
>>> from sys import getsizeof
>>> getsizeof(Right()), getsizeof(Wrong())
(56, 72)
This is because the Base's slot descriptor has a slot separate from the Wrong's. This shouldn't usually come up, but it could:
>>> w = Wrong()
>>> w.foo = 'foo'
>>> Base.foo.__get__(w)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: foo
>>> Wrong.foo.__get__(w)
'foo'
The biggest caveat is for multiple inheritance - multiple "parent classes with nonempty slots" cannot be combined.
To accommodate this restriction, follow best practices: Factor out all but one or all parents' abstraction which their concrete class respectively and your new concrete class collectively will inherit from - giving the abstraction(s) empty slots (just like abstract base classes in the standard library).
See section on multiple inheritance below for an example.
To have attributes named in __slots__
to actually be stored in slots instead of a __dict__
, a class must inherit from object
.
To prevent the creation of a __dict__
, you must inherit from object
and all classes in the inheritance must declare __slots__
and none of them can have a '__dict__'
entry.
There are a lot of details if you wish to keep reading.
__slots__
: Faster attribute access.The creator of Python, Guido van Rossum, states that he actually created __slots__
for faster attribute access.
It is trivial to demonstrate measurably significant faster access:
import timeit
class Foo(object): __slots__ = 'foo',
class Bar(object): pass
slotted = Foo()
not_slotted = Bar()
def get_set_delete_fn(obj):
def get_set_delete():
obj.foo = 'foo'
obj.foo
del obj.foo
return get_set_delete
and
>>> min(timeit.repeat(get_set_delete_fn(slotted)))
0.2846834529991611
>>> min(timeit.repeat(get_set_delete_fn(not_slotted)))
0.3664822799983085
The slotted access is almost 30% faster in Python 3.5 on Ubuntu.
>>> 0.3664822799983085 / 0.2846834529991611
1.2873325658284342
In Python 2 on Windows I have measured it about 15% faster.
__slots__
: Memory SavingsAnother purpose of __slots__
is to reduce the space in memory that each object instance takes up.
My own contribution to the documentation clearly states the reasons behind this:
The space saved over using
__dict__
can be significant.
SQLAlchemy attributes a lot of memory savings to __slots__
.
To verify this, using the Anaconda distribution of Python 2.7 on Ubuntu Linux, with guppy.hpy
(aka heapy) and sys.getsizeof
, the size of a class instance without __slots__
declared, and nothing else, is 64 bytes. That does not include the __dict__
. Thank you Python for lazy evaluation again, the __dict__
is apparently not called into existence until it is referenced, but classes without data are usually useless. When called into existence, the __dict__
attribute is a minimum of 280 bytes additionally.
In contrast, a class instance with __slots__
declared to be ()
(no data) is only 16 bytes, and 56 total bytes with one item in slots, 64 with two.
For 64 bit Python, I illustrate the memory consumption in bytes in Python 2.7 and 3.6, for __slots__
and __dict__
(no slots defined) for each point where the dict grows in 3.6 (except for 0, 1, and 2 attributes):
Python 2.7 Python 3.6
attrs __slots__ __dict__* __slots__ __dict__* | *(no slots defined)
none 16 56 + 272† 16 56 + 112† | †if __dict__ referenced
one 48 56 + 272 48 56 + 112
two 56 56 + 272 56 56 + 112
six 88 56 + 1040 88 56 + 152
11 128 56 + 1040 128 56 + 240
22 216 56 + 3344 216 56 + 408
43 384 56 + 3344 384 56 + 752
So, in spite of smaller dicts in Python 3, we see how nicely __slots__
scale for instances to save us memory, and that is a major reason you would want to use __slots__
.
Just for completeness of my notes, note that there is a one-time cost per slot in the class's namespace of 64 bytes in Python 2, and 72 bytes in Python 3, because slots use data descriptors like properties, called "members".
>>> Foo.foo
<member 'foo' of 'Foo' objects>
>>> type(Foo.foo)
<class 'member_descriptor'>
>>> getsizeof(Foo.foo)
72
__slots__
:To deny the creation of a __dict__
, you must subclass object
:
class Base(object):
__slots__ = ()
now:
>>> b = Base()
>>> b.a = 'a'
Traceback (most recent call last):
File "<pyshell#38>", line 1, in <module>
b.a = 'a'
AttributeError: 'Base' object has no attribute 'a'
Or subclass another class that defines __slots__
class Child(Base):
__slots__ = ('a',)
and now:
c = Child()
c.a = 'a'
but:
>>> c.b = 'b'
Traceback (most recent call last):
File "<pyshell#42>", line 1, in <module>
c.b = 'b'
AttributeError: 'Child' object has no attribute 'b'
To allow __dict__
creation while subclassing slotted objects, just add '__dict__'
to the __slots__
(note that slots are ordered, and you shouldn't repeat slots that are already in parent classes):
class SlottedWithDict(Child):
__slots__ = ('__dict__', 'b')
swd = SlottedWithDict()
swd.a = 'a'
swd.b = 'b'
swd.c = 'c'
and
>>> swd.__dict__
{'c': 'c'}
Or you don't even need to declare __slots__
in your subclass, and you will still use slots from the parents, but not restrict the creation of a __dict__
:
class NoSlots(Child): pass
ns = NoSlots()
ns.a = 'a'
ns.b = 'b'
And:
>>> ns.__dict__
{'b': 'b'}
However, __slots__
may cause problems for multiple inheritance:
class BaseA(object):
__slots__ = ('a',)
class BaseB(object):
__slots__ = ('b',)
Because creating a child class from parents with both non-empty slots fails:
>>> class Child(BaseA, BaseB): __slots__ = ()
Traceback (most recent call last):
File "<pyshell#68>", line 1, in <module>
class Child(BaseA, BaseB): __slots__ = ()
TypeError: Error when calling the metaclass bases
multiple bases have instance lay-out conflict
If you run into this problem, You could just remove __slots__
from the parents, or if you have control of the parents, give them empty slots, or refactor to abstractions:
from abc import ABC
class AbstractA(ABC):
__slots__ = ()
class BaseA(AbstractA):
__slots__ = ('a',)
class AbstractB(ABC):
__slots__ = ()
class BaseB(AbstractB):
__slots__ = ('b',)
class Child(AbstractA, AbstractB):
__slots__ = ('a', 'b')
c = Child() # no problem!
'__dict__'
to __slots__
to get dynamic assignment:class Foo(object):
__slots__ = 'bar', 'baz', '__dict__'
and now:
>>> foo = Foo()
>>> foo.boink = 'boink'
So with '__dict__'
in slots we lose some of the size benefits with the upside of having dynamic assignment and still having slots for the names we do expect.
When you inherit from an object that isn't slotted, you get the same sort of semantics when you use __slots__
- names that are in __slots__
point to slotted values, while any other values are put in the instance's __dict__
.
Avoiding __slots__
because you want to be able to add attributes on the fly is actually not a good reason - just add "__dict__"
to your __slots__
if this is required.
You can similarly add __weakref__
to __slots__
explicitly if you need that feature.
The namedtuple builtin make immutable instances that are very lightweight (essentially, the size of tuples) but to get the benefits, you need to do it yourself if you subclass them:
from collections import namedtuple
class MyNT(namedtuple('MyNT', 'bar baz')):
"""MyNT is an immutable and lightweight object"""
__slots__ = ()
usage:
>>> nt = MyNT('bar', 'baz')
>>> nt.bar
'bar'
>>> nt.baz
'baz'
And trying to assign an unexpected attribute raises an AttributeError
because we have prevented the creation of __dict__
:
>>> nt.quux = 'quux'
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'MyNT' object has no attribute 'quux'
You can allow __dict__
creation by leaving off __slots__ = ()
, but you can't use non-empty __slots__
with subtypes of tuple.
Even when non-empty slots are the same for multiple parents, they cannot be used together:
class Foo(object):
__slots__ = 'foo', 'bar'
class Bar(object):
__slots__ = 'foo', 'bar' # alas, would work if empty, i.e. ()
>>> class Baz(Foo, Bar): pass
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: Error when calling the metaclass bases
multiple bases have instance lay-out conflict
Using an empty __slots__
in the parent seems to provide the most flexibility, allowing the child to choose to prevent or allow (by adding '__dict__'
to get dynamic assignment, see section above) the creation of a __dict__
:
class Foo(object): __slots__ = ()
class Bar(object): __slots__ = ()
class Baz(Foo, Bar): __slots__ = ('foo', 'bar')
b = Baz()
b.foo, b.bar = 'foo', 'bar'
You don't have to have slots - so if you add them, and remove them later, it shouldn't cause any problems.
Going out on a limb here: If you're composing mixins or using abstract base classes, which aren't intended to be instantiated, an empty __slots__
in those parents seems to be the best way to go in terms of flexibility for subclassers.
To demonstrate, first, let's create a class with code we'd like to use under multiple inheritance
class AbstractBase:
__slots__ = ()
def __init__(self, a, b):
self.a = a
self.b = b
def __repr__(self):
return f'{type(self).__name__}({repr(self.a)}, {repr(self.b)})'
We could use the above directly by inheriting and declaring the expected slots:
class Foo(AbstractBase):
__slots__ = 'a', 'b'
But we don't care about that, that's trivial single inheritance, we need another class we might also inherit from, maybe with a noisy attribute:
class AbstractBaseC:
__slots__ = ()
@property
def c(self):
print('getting c!')
return self._c
@c.setter
def c(self, arg):
print('setting c!')
self._c = arg
Now if both bases had nonempty slots, we couldn't do the below. (In fact, if we wanted, we could have given AbstractBase
nonempty slots a and b, and left them out of the below declaration - leaving them in would be wrong):
class Concretion(AbstractBase, AbstractBaseC):
__slots__ = 'a b _c'.split()
And now we have functionality from both via multiple inheritance, and can still deny __dict__
and __weakref__
instantiation:
>>> c = Concretion('a', 'b')
>>> c.c = c
setting c!
>>> c.c
getting c!
Concretion('a', 'b')
>>> c.d = 'd'
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'Concretion' object has no attribute 'd'
__class__
assignment with another class that doesn't have them (and you can't add them) unless the slot layouts are identical. (I am very interested in learning who is doing this and why.)You may be able to tease out further caveats from the rest of the __slots__
documentation (the 3.7 dev docs are the most current), which I have made significant recent contributions to.
The current top answers cite outdated information and are quite hand-wavy and miss the mark in some important ways.
__slots__
when instantiating lots of objects"I quote:
"You would want to use
__slots__
if you are going to instantiate a lot (hundreds, thousands) of objects of the same class."
Abstract Base Classes, for example, from the collections
module, are not instantiated, yet __slots__
are declared for them.
Why?
If a user wishes to deny __dict__
or __weakref__
creation, those things must not be available in the parent classes.
__slots__
contributes to reusability when creating interfaces or mixins.
It is true that many Python users aren't writing for reusability, but when you are, having the option to deny unnecessary space usage is valuable.
__slots__
doesn't break picklingWhen pickling a slotted object, you may find it complains with a misleading TypeError
:
>>> pickle.loads(pickle.dumps(f))
TypeError: a class that defines __slots__ without defining __getstate__ cannot be pickled
This is actually incorrect. This message comes from the oldest protocol, which is the default. You can select the latest protocol with the -1
argument. In Python 2.7 this would be 2
(which was introduced in 2.3), and in 3.6 it is 4
.
>>> pickle.loads(pickle.dumps(f, -1))
<__main__.Foo object at 0x1129C770>
in Python 2.7:
>>> pickle.loads(pickle.dumps(f, 2))
<__main__.Foo object at 0x1129C770>
in Python 3.6
>>> pickle.loads(pickle.dumps(f, 4))
<__main__.Foo object at 0x1129C770>
So I would keep this in mind, as it is a solved problem.
The first paragraph is half short explanation, half predictive. Here's the only part that actually answers the question
The proper use of
__slots__
is to save space in objects. Instead of having a dynamic dict that allows adding attributes to objects at anytime, there is a static structure which does not allow additions after creation. This saves the overhead of one dict for every object that uses slots
The second half is wishful thinking, and off the mark:
While this is sometimes a useful optimization, it would be completely unnecessary if the Python interpreter was dynamic enough so that it would only require the dict when there actually were additions to the object.
Python actually does something similar to this, only creating the __dict__
when it is accessed, but creating lots of objects with no data is fairly ridiculous.
The second paragraph oversimplifies and misses actual reasons to avoid __slots__
. The below is not a real reason to avoid slots (for actual reasons, see the rest of my answer above.):
They change the behavior of the objects that have slots in a way that can be abused by control freaks and static typing weenies.
It then goes on to discuss other ways of accomplishing that perverse goal with Python, not discussing anything to do with __slots__
.
The third paragraph is more wishful thinking. Together it is mostly off-the-mark content that the answerer didn't even author and contributes to ammunition for critics of the site.
Create some normal objects and slotted objects:
>>> class Foo(object): pass
>>> class Bar(object): __slots__ = ()
Instantiate a million of them:
>>> foos = [Foo() for f in xrange(1000000)]
>>> bars = [Bar() for b in xrange(1000000)]
Inspect with guppy.hpy().heap()
:
>>> guppy.hpy().heap()

Access the regular objects and their __dict__
and inspect again:
>>> for f in foos:
... f.__dict__

This is consistent with the history of Python, from Unifying types and classes in Python 2.2
If you subclass a built-in type, extra space is automatically added to the instances to accomodate
__dict__
and__weakrefs__
. (The__dict__
is not initialized until you use it though, so you shouldn't worry about the space occupied by an empty dictionary for each instance you create.) If you don't need this extra space, you can add the phrase "__slots__ = []
" to your class.
cat "input files" > "output files"
This works in PowerShell, which is the Windows preferred shell in current Windows versions, therefore it works. It is also the only version of the answers above to work with large files, where 'type' or 'copy' fails.
For Kotlin devs this is the version with comparing formatted strings approach:
val sdf = SimpleDateFormat("yyMMdd")
if (sdf.format(date1) == sdf.format(date2)) {
// same day
}
It's not the best way, but it's short and working.
From the docs of the flush
method:
Flushes the output stream and forces any buffered output bytes to be written out. The general contract of flush is that calling it is an indication that, if any bytes previously written have been buffered by the implementation of the output stream, such bytes should immediately be written to their intended destination.
The buffering is mainly done to improve the I/O performance. More on this can be read from this article: Tuning Java I/O Performance.
You can specify it as text, but add pettern, that match numbers only:
<input type="text" pattern="\d*" maxlength="2">
It works perfect and also on mobile ( tested on iOS 8 and Android ) pops out the number keyboard.
Here is a simple Javascript Tuple implementation:
var Tuple = (function () {
function Tuple(Item1, Item2) {
var item1 = Item1;
var item2 = Item2;
Object.defineProperty(this, "Item1", {
get: function() { return item1 }
});
Object.defineProperty(this, "Item2", {
get: function() { return item2 }
});
}
return Tuple;
})();
var tuple = new Tuple("Bob", 25); // Instantiation of a new Tuple
var name = tuple.Item1; // Assignment. name will be "Bob"
tuple.Item1 = "Kirk"; // Will not set it. It's immutable.
This is a 2-tuple, however, you could modify my example to support 3,4,5,6 etc. tuples.
You can use it to transform some aggregate functions into analytic:
SELECT MAX(date)
FROM mytable
will return 1
row with a single maximum,
SELECT MAX(date) OVER (ORDER BY id)
FROM mytable
will return all rows with a running maximum.
I think the problem you're having is that in some earlier commit, you've accidentally added .DS_Store
files to the repository. Of course, once a file is tracked in your repository, it will continue to be tracked even if it matches an entry in an applicable .gitignore file.
You have to manually remove the .DS_Store
files that were added to your repository. You can use
git rm --cached .DS_Store
Once removed, git should ignore it. You should only need the following line in your root .gitignore
file: .DS_Store
. Don't forget the period!
git rm --cached .DS_Store
removes only .DS_Store
from the current directory. You can use
find . -name .DS_Store -print0 | xargs -0 git rm --ignore-unmatch
to remove all .DS_Stores
from the repository.
Felt tip: Since you probably never want to include .DS_Store
files, make a global rule. First, make a global .gitignore
file somewhere, e.g.
echo .DS_Store >> ~/.gitignore_global
Now tell git to use it for all repositories:
git config --global core.excludesfile ~/.gitignore_global

You don't have to set either of them. PYTHONPATH can be set to point to additional directories with private libraries in them. If PYTHONHOME is not set, Python defaults to using the directory where python.exe was found, so that dir should be in PATH.

The ready
event occurs after the HTML document has been loaded, while the onload
event occurs later, when all content (e.g. images) also has been loaded.
The onload
event is a standard event in the DOM, while the ready
event is specific to jQuery. The purpose of the ready
event is that it should occur as early as possible after the document has loaded, so that code that adds functionality to the elements in the page doesn't have to wait for all content to load.

Beside the recommended
DESCRIBE TABLE <itab-Name> LINES <variable>
there is also the system variable SY-TFILL
.
From documentation:
After the statements DESCRIBE TABLE, LOOP AT and READ TABLE, the number of rows of the accessed internal table.
Example script:
REPORT ytest.
DATA pf_exclude TYPE TABLE OF sy-ucomm WITH HEADER LINE.
START-OF-SELECTION.
APPEND '1' TO pf_exclude.
APPEND '2' TO pf_exclude.
APPEND '3' TO pf_exclude.
APPEND '4' TO pf_exclude.
WRITE: / 'sy-tfill = ', sy-tfill.
DESCRIBE TABLE pf_exclude.
WRITE: / 'sy-tfill = ', sy-tfill, 'after describe table'.
sy-tfill = 0. "Reset
READ TABLE pf_exclude INDEX 1 TRANSPORTING NO FIELDS.
WRITE: / 'sy-tfill = ', sy-tfill, 'after read table'.
sy-tfill = 0. "Reset
LOOP AT pf_exclude.
WRITE: / 'sy-tfill = ', sy-tfill, 'in loop with', pf_exclude.
sy-tfill = 0. "Reset
ENDLOOP.
The result:
sy-tfill = 0
sy-tfill = 4 after describe tabl
sy-tfill = 4 after read table
sy-tfill = 4 in loop with 1
sy-tfill = 0 in loop with 2
sy-tfill = 0 in loop with 3
sy-tfill = 0 in loop with 4
Please get attention of the value 0 for the 2nd entry: SY-TFILL
is not updated with each step, only after the first loop.
I recommend the usage SY-TFILL only, if you need it direct after the READ
(1)... If there are other commands between the READ
and the usage of SY-TFILL, there is always the danger of a change of the system variable.
(1) or describe table.
In advance of my questions being answered, this is how I'd go about it:
Minimize the number of statements and the work they do issued in relative terms.
All scenarios assume you have a table of IDs (PURGE_IDS
) to delete from TABLE_1
, TABLE_2
, etc.
Consider Using CREATE TABLE AS SELECT for really large deletes
If there's no concurrent activity, and you're deleting 30+ % of the rows in one or more of the tables, don't delete; perform a create table as select
with the rows you wish to keep, and swap the new table out for the old table. INSERT /*+ APPEND */ ... NOLOGGING
is surprisingly cheap if you can afford it. Even if you do have some concurrent activity, you may be able to use Online Table Redefinition to rebuild the table in-place.
Don't run DELETE statements you know won't delete any rows
If an ID value exists in at most one of the six tables, then keep track of which IDs you've deleted - and don't try to delete those IDs from any of the other tables.
CREATE TABLE TABLE1_PURGE NOLOGGING
AS
SELECT ID FROM PURGE_IDS INNER JOIN TABLE_1 ON PURGE_IDS.ID = TABLE_1.ID;
DELETE FROM TABLE1 WHERE ID IN (SELECT ID FROM TABLE1_PURGE);
DELETE FROM PURGE_IDS WHERE ID IN (SELECT ID FROM TABLE1_PURGE);
DROP TABLE TABLE1_PURGE;
and repeat.
Manage Concurrency if you have to
Another way is to use PL/SQL looping over the tables, issuing a rowcount-limited delete statement. This is most likely appropriate if there's significant insert/update/delete concurrent load against the tables you're running the deletes against.
declare
l_sql varchar2(4000);
begin
for i in (select table_name from all_tables
where table_name in ('TABLE_1', 'TABLE_2', ...)
order by table_name);
loop
l_sql := 'delete from ' || i.table_name ||
' where id in (select id from purge_ids) ' ||
' and rownum <= 1000000';
loop
commit;
execute immediate l_sql;
exit when sql%rowcount <> 1000000; -- if we delete less than 1,000,000
end loop; -- no more rows need to be deleted!
end loop;
commit;
end;
People arguing about the corner radius being slightly increased but actually that's not the case.
From this blog:
A ‘secret’ of Apple’s physical products is that they avoid tangency (where a radius meets a line at a single point) and craft their surfaces with what’s called curvature continuity.
You don't need to apply corner radius to icons for iOS. Just provide square icons. But if you still want to know how, the actual shape is called Squircle and below is the formula:
Simplest answer:
the return code from a function can be only a value in the range from 0 to 255 . To store this value in a variable you have to do like in this example:
#!/bin/bash
function returnfunction {
# example value between 0-255 to be returned
return 23
}
# note that the value has to be stored immediately after the function call :
returnfunction
myreturnvalue=$?
echo "myreturnvalue is "$myreturnvalue
The m2e plugin uses it's own distribution of Maven, packaged with the plugin.
In order to use Maven from command line, you need to have it installed as a standalone application. Here is an instruction explaining how to do it in Windows
Once Maven is properly installed (i.e. be sure that MAVEN_HOME
, JAVA_HOME
and PATH
variables are set correctly): you must run mvn eclipse:eclipse
from the directory containing the pom.xml
.
User Auth::user()->id
instead.
Here is the correct way :
//PostController
Post::create(request([
'body' => request('body'),
'title' => request('title'),
'user_id' => Auth::user()->id
]));
If your user is authenticated, Then Auth::user()->id
will do the trick.
According to Mozilla MDN: "The X-Forwarded-For (XFF) header is a de-facto standard header for identifying the originating IP address of a client."
They publish clear information in their X-Forwarded-For article.
a very common try_files line which can be applied on your condition is
location / {
try_files $uri $uri/ /test/index.html;
}
you probably understand the first part, location /
matches all locations, unless it's matched by a more specific location, like location /test
for example
The second part ( the try_files
) means when you receive a URI that's matched by this block try $uri
first, for example http://example.com/images/image.jpg
nginx will try to check if there's a file inside /images
called image.jpg
if found it will serve it first.
Second condition is $uri/
which means if you didn't find the first condition $uri
try the URI as a directory, for example http://example.com/images/
, ngixn will first check if a file called images
exists then it wont find it, then goes to second check $uri/
and see if there's a directory called images
exists then it will try serving it.
Side note: if you don't have autoindex on
you'll probably get a 403 forbidden error, because directory listing is forbidden by default.
EDIT: I forgot to mention that if you have
index
defined, nginx will try to check if the index exists inside this folder before trying directory listing.
Third condition /test/index.html
is considered a fall back option, (you need to use at least 2 options, one and a fall back), you can use as much as you can (never read of a constriction before), nginx will look for the file index.html
inside the folder test
and serve it if it exists.
If the third condition fails too, then nginx will serve the 404 error page.
Also there's something called named locations, like this
location @error {
}
You can call it with try_files
like this
try_files $uri $uri/ @error;
TIP: If you only have 1 condition you want to serve, like for example inside folder images
you only want to either serve the image or go to 404 error, you can write a line like this
location /images {
try_files $uri =404;
}
which means either serve the file or serve a 404 error, you can't use only $uri
by it self without =404
because you need to have a fallback option.
You can also choose which ever error code you want, like for example:
location /images {
try_files $uri =403;
}
This will show a forbidden error if the image doesn't exist, or if you use 500 it will show server error, etc ..
If you work on Linux you can try this:
setwd(system("pwd", intern = T) )
It works for me.
Serialization provides default functionality to store and later recreate the object. It uses verbose format to define the whole graph of objects to be stored e.g. suppose you have a linkedList and you code like below, then the default serialization will discover all the objects which are linked and will serialize. In default serialization the object is constructed entirely from its stored bits, with no constructor calls.
ObjectOutputStream oos = new ObjectOutputStream(
new FileOutputStream("/Users/Desktop/files/temp.txt"));
oos.writeObject(linkedListHead); //writing head of linked list
oos.close();
But if you want restricted serialization or don't want some portion of your object to be serialized then use Externalizable. The Externalizable interface extends the Serializable interface and adds two methods, writeExternal() and readExternal(). These are automatically called while serialization or deserialization. While working with Externalizable we should remember that the default constructer should be public else the code will throw exception. Please follow the below code:
public class MyExternalizable implements Externalizable
{
private String userName;
private String passWord;
private Integer roll;
public MyExternalizable()
{
}
public MyExternalizable(String userName, String passWord, Integer roll)
{
this.userName = userName;
this.passWord = passWord;
this.roll = roll;
}
@Override
public void writeExternal(ObjectOutput oo) throws IOException
{
oo.writeObject(userName);
oo.writeObject(roll);
}
@Override
public void readExternal(ObjectInput oi) throws IOException, ClassNotFoundException
{
userName = (String)oi.readObject();
roll = (Integer)oi.readObject();
}
public String toString()
{
StringBuilder b = new StringBuilder();
b.append("userName: ");
b.append(userName);
b.append(" passWord: ");
b.append(passWord);
b.append(" roll: ");
b.append(roll);
return b.toString();
}
public static void main(String[] args)
{
try
{
MyExternalizable m = new MyExternalizable("nikki", "student001", 20);
System.out.println(m.toString());
ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream("/Users/Desktop/files/temp1.txt"));
oos.writeObject(m);
oos.close();
System.out.println("***********************************************************************");
ObjectInputStream ois = new ObjectInputStream(new FileInputStream("/Users/Desktop/files/temp1.txt"));
MyExternalizable mm = (MyExternalizable)ois.readObject();
mm.toString();
System.out.println(mm.toString());
}
catch (ClassNotFoundException ex)
{
Logger.getLogger(MyExternalizable.class.getName()).log(Level.SEVERE, null, ex);
}
catch(IOException ex)
{
Logger.getLogger(MyExternalizable.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
Here if you comment the default constructer then the code will throw below exception:
java.io.InvalidClassException: javaserialization.MyExternalizable;
javaserialization.MyExternalizable; no valid constructor.
We can observe that as password is sensitive information, so i am not serializing it in writeExternal(ObjectOutput oo) method and not setting the value of same in readExternal(ObjectInput oi). That's the flexibility that is provided by Externalizable.
The output of the above code is as per below:
userName: nikki passWord: student001 roll: 20
***********************************************************************
userName: nikki passWord: null roll: 20
We can observe as we are not setting the value of passWord so it's null.
The same can also be achieved by declaring the password field as transient.
private transient String passWord;
Hope it helps. I apologize if i made any mistakes. Thanks.
When the workbook first opens, execute this code:
alertTime = Now + TimeValue("00:02:00")
Application.OnTime alertTime, "EventMacro"
Then just have a macro in the workbook called "EventMacro" that will repeat it.
Public Sub EventMacro()
'... Execute your actions here'
alertTime = Now + TimeValue("00:02:00")
Application.OnTime alertTime, "EventMacro"
End Sub
Just a minor word of warning... a lot of environments use, or need, "\r\n" and not just "\n". I ran into an issue with Visual Studio not matching my regex string at the end of the line because I left off the "\r" of "\r\n", so my string couldn't match with a missing invisible character.
So, if you are doing a find, or a replace, consider the "\r".
For a little more detail on "\r" and "\n", see: https://stackoverflow.com/a/3451192/4427457
A more advanced way would be to use butterknife bindview. This eliminates redundant code.
In your gradle under dependencies; add this 2 lines.
compile('com.jakewharton:butterknife:8.5.1') {
exclude module: 'support-compat'
}
apt 'com.jakewharton:butterknife-compiler:8.5.1'
Then sync up. Example binding edittext in MainActivity
import butterknife.BindView;
import butterknife.ButterKnife;
public class MainActivity {
@BindView(R.id.name) EditTextView mName;
...
public void onCreate(Bundle savedInstanceState){
ButterKnife.bind(this);
...
}
}
But this is an alternative once you feel more comfortable or starting to work with lots of data.
I searched for hours, and I tried almost everything suggested.
This worked for almost every entity :
$input = "ažškunrukiš ? àéò ??? ©€ ?? ? ?? ? R?";
echo htmlentities($input, ENT_HTML5 , 'UTF-8');
result :
āžšķūņrūķīš ○ àéò ∀∂∋ ©€ ♣♦ ↠ ↔↛ ↙ ℜ℞rx;
Declare @MyInt int
Set @MyInt = ( Select Count(*) From MyTable )
If @MyInt > 0
Begin
Print 'There''s something in the table'
End
I'm not sure if this is your issue, but you have to esacpe the single quote in the print statement with a second single quote. While you can use SELECT to populate the variable, using SET as you have done here is just fine and clearer IMO. In addition, you can be guaranteed that Count(*) will never return a negative value so you need only check whether it is greater than zero.
I had this same problem installing SQL Server 2014. Turns out it was due to a Windows Phone toolkit that I had installed back in 2010. If you run into this, make sure you uninstall any Windows phone stuff that isn't current.
I figured it out by looking at the log, which can be found by clicking "Detailed Report," which opens an HTML file. The file path is conveniently displayed within the HTML page. Open the directory that the file is in and look for "Detail.txt." Then search for the word "fail."
In my case there was a line showing WP_[something] as "Installed." I searched for the WP_ item and came across some blog posts about trouble uninstalling Windows Phone toolkits.
When I attempted to uninstall the windows phone I ran into more trouble. The uninstaller wanted to install three packages instead of uninstalling the toolkit. Eventually found this blog post: http://blogs.msdn.com/b/astebner/archive/2010/07/12/10037442.aspx linking to this XNA cleanup tool: http://blogs.msdn.com/b/astebner/archive/2009/04/10/9544320.aspx.
I ran the cleanup tool and finally SQL Server installer passed the check and allowed me to install. Hope this helps someone.
By dragging and dropping the dll onto 'regasm' you can register it. You can open two 'Window Explorer' windows. One will contain the dll you wish to register. The 2nd window will be the location of the 'regasm' application. Scroll down in both windows so that you have a view of both the dll and 'regasm'. It helps to reduce the size of the two windows so they are side-by-side. Be sure to drag the dll over the 'regasm' that is labeled 'application'. There are several 'regasm' files but you only want the application.
On Linux I would suggest,
# FILE_TO_BE_ATTACHED=abc.gz
uuencode abc.gz abc.gz > abc.gz.enc # This is optional, but good to have
# to prevent binary file corruption.
# also it make sure to get original
# file on other system, w/o worry of endianness
# Sending Mail, multiple attachments, and multiple receivers.
echo "Body Part of Mail" | mailx -s "Subject Line" -a attachment1 -a abc.gz.enc "[email protected] [email protected]"
Upon receiving mail attachment, if you have used uuencode, you would need uudecode
uudecode abc.gz.enc
# This will generate file as original with name as same as the 2nd argument for uuencode.
I tried to copy an xml file from one location to another. Here is my code:
public void SaveStockInfoToAnotherFile()
{
string sourcePath = @"C:\inetpub\wwwroot";
string destinationPath = @"G:\ProjectBO\ForFutureAnalysis";
string sourceFileName = "startingStock.xml";
string destinationFileName = DateTime.Now.ToString("yyyyMMddhhmmss") + ".xml"; // Don't mind this. I did this because I needed to name the copied files with respect to time.
string sourceFile = System.IO.Path.Combine(sourcePath, sourceFileName);
string destinationFile = System.IO.Path.Combine(destinationPath, destinationFileName);
if (!System.IO.Directory.Exists(destinationPath))
{
System.IO.Directory.CreateDirectory(destinationPath);
}
System.IO.File.Copy(sourceFile, destinationFile, true);
}
Then I called this function inside a timer_elapsed function of certain interval which I think you don't need to see. It worked. Hope this helps.
BrixenDK is right.

mappedby
speaks for itself, it tells hibernate not to map this field. it's already mapped by this field [name="field"].
field is in the other entity (name of the variable in the class not the table in the database)
..
If you don't do that, hibernate will map this two relation as it's not the same relation
so we need to tell hibernate to do the mapping in one side only and co-ordinate between them.
It is because there is no default ROOT web application. When you create some web app and deploy it to Tomcat using Eclipse, then you will be able to access it with the URL in the form of
http://localhost:8080/YourWebAppName
where YourWebAppName is some name you give to your web app (the so called application context path).
Quote from Jetty Documentation Wiki (emphasis mine):
The context path is the prefix of a URL path that is used to select the web application to which an incoming request is routed. Typically a URL in a Java servlet server is of the format
http://hostname.com/contextPath/servletPath/pathInfo
, where each of the path elements may be zero or more / separated elements. If there is no context path, the context is referred to as the root context.
If you still want the default app which is accessed with the URL of the form
http://localhost:8080
or if you change the default 8080 port to 80, then just
http://localhost
i.e. without application context path read the following (quote from Tutorial: Installing Tomcat 7 and Using it with Eclipse, emphasis mine):
Copy the ROOT (default) Web app into Eclipse. Eclipse forgets to copy the default apps (ROOT, examples, docs, etc.) when it creates a Tomcat folder inside the Eclipse workspace. Go to C:\apache-tomcat-7.0.34\webapps and copy the ROOT folder. Then go to your Eclipse workspace, go to the .metadata folder, and search for "wtpwebapps". You should find something like
C:\your-eclipse-workspace-location\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps
(or.../tmp1/wtpwebapps
if you already had another server registered in Eclipse). Go to thewtpwebapps
folder and paste ROOT (say "yes" if asked if you want to merge/replace folders/files). Then reloadhttp://localhost/
to see the Tomcat welcome page.
Expanding on Chris' answer. I managed to reverse engineer the token generation process.
The token for the request is based on the text and a global TKK variable set in the page script. These are hashed in JavaScript thus resulting in the tk param.
Somewhere in the page script you will find something like this:
TKK='403413';

I managed to successfully port this to python in my fork of gTTS, so I know this works.
Edit: By now the token generation code used by gTTS has been moved into gTTS-token.
Edit 2: Google has changed the API (somewhere around 2016-05-10), this method requires some modification. I'm currently working on this. In the meantime changing the client to tw-ob seems to work.
Edit 3:
The changes are minor, yet annoying to say the least. The TKK now has two parts. Looking something like 406986.2817744745
. As you can see the first part has remained the same. The second part is the sum of two seemingly random numbers. TKK=eval('((function(){var a\x3d2680116022;var b\x3d137628723;return 406986+\x27.\x27+(a+b)})())');
Here \x3d
means =
and \x27
is '
. Both a and b change every UTC minute. At one of the final steps in the algorithm the token is XORed by the second part.
The new token generation code is:

It looks like Google actively frowns on using IP-to-location mapping:
https://developers.google.com/maps/articles/geolocation?hl=en
That article encourages using the W3C geolocation API. I was a little skeptical, but it looks like almost every major browser already supports the geolocation API:
Here's an example of a reverse proxy (as a load balancer).
A client surfs to website.com and the server it hits has a reverse proxy running on it. The reverse proxy happens to be Pound. Pound takes the request and sends it to one of the three application servers sitting behind it. In this example, Pound is a load balancer. That is, it is balancing the load between three application servers.
The application servers serve up the website content back to the client.

Building upon the fiddle from @tim, this version tightens the scope and formatting, and converts bind()

as the handle instead of the entire row. In my use case, I have input
fields so the "drag anywhere on the row" approach felt confusing.

For those who are still looking for an answer. Here is a recursive approach to get the paths in a dictionary.
import os
def list_files(startpath):
for root, dirs, files in os.walk(startpath):
dir_content = []
for dir in dirs:
go_inside = os.path.join(startpath, dir)
dir_content.append(list_files(go_inside))
files_lst = []
for f in files:
files_lst.append(f)
return {'name': root, 'files': files_lst, 'dirs': dir_content}
You probably want to add one day rather than 24 hours. Not all days have 24 hours due to (among other circumstances) daylight saving time:

Pickle save:
try:
import cPickle as pickle
except ImportError: # Python 3.x
import pickle
with open('data.p', 'wb') as fp:
pickle.dump(data, fp, protocol=pickle.HIGHEST_PROTOCOL)
See the pickle module documentation for additional information regarding the protocol
argument.
Pickle load:
with open('data.p', 'rb') as fp:
data = pickle.load(fp)
JSON save:
import json
with open('data.json', 'w') as fp:
json.dump(data, fp)
Supply extra arguments, like sort_keys
or indent
, to get a pretty result. The argument sort_keys will sort the keys alphabetically and indent will indent your data structure with indent=N
spaces.
json.dump(data, fp, sort_keys=True, indent=4)
JSON load:
with open('data.json', 'r') as fp:
data = json.load(fp)
There are a few issues here. Firstly, the async load method you specified:
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load('jquery', '1.3.1');
google.setOnLoadCallback(function() {
// do stuff
});
</script>
has a couple of issues. Script tags pause the page load while they are retrieved (if necessary). Now if they're slow to load this is bad but jQuery is small. The real problem with the above method is that because the jquery.js load happens independently for many pages, they will finish loading and render before jquery has loaded so any jquery styling you do will be a visible change for the user.
The other way is:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.1/jquery.min.js"></script>
Try some simple examples like, have a simple table and change the background of the cells to yellow with the setOnLoadCallback() method vs $(document).ready() with a static jquery.min.js load. The second method will have no noticeable flicker. The first will. Personally I think that's not a good user experience.
As an example run this:
<html>
<head>
<title>Layout</title>
<style type="text/css">
.odd { background-color: yellow; }
</style>
</head>
<body>
<table>
<tr><th>One</th><th>Two</th></tr>
<tr><td>Three</td><td>Four</td></tr>
<tr><td>Five</td><td>Six</td></tr>
<tr><td>Seven</td><td>Nine</td></tr>
<tr><td>Nine</td><td>Ten</td></tr>
</table>
<script src="http://www.google.com/jsapi"></script>
<script>
google.load("jquery", "1.3.1");
google.setOnLoadCallback(function() {
$(function() {
$("tr:odd").addClass("odd");
});
});
</script>
</body>
</html>
You (should) see the table appear and then the rows go yellow.
The second problem with the google.load() method is that it only hosts a limited range of files. This is a problem for jquery since it is extremely plug-in dependent. If you try and include a jquery plugin with a <script src="...">
tag and google.load()
the plug-in will probably fail with messages of "jQuery is not defined" because it hasn't loaded yet. I don't really see a way around this.
The third problem (with either method) is that they are one external load. Assuming you have some plugins and your own Javascript code you're up to a minimum of two external requests to load your Javascript. You're probably better off getting jquery, all relevant plug-ins and your own code and putting it into one minified file.
From Should You Use Google's Ajax Libraries API for Hosting?:
As to load times, you're actually loading two scripts - the jsapi script and the mootools script (the compressed version from above). So that is two connections, rather than one. In my experience, I found that the load time was actually 2-3 times slower than loading from my own personal shared server, even though it was coming from Google, and my version of the compressed file was a couple of K larger than Google's. This, even after the file had loaded and (presumably) cached. So for me, since the bandwidth doesn't matter much, isn't going to matter.
Lastly you have the potential problem of a paranoid browser flagging the request as some sort of XSS attempt. It's not typically a problem with default settings but on corporate networks where the user may not have control over which browser they use let alone the security settings you may have a problem.
So in the end I can't really see me using the Google AJAX API for jQuery at least (the more "complete" APIs are a different story in some ways) much except to post examples here.
I would like to answer this question from a coding-politics perspective, which may or may not be helpful to anyone. But particularly when you're dealing with tools that are intended for 9-5 corporate programmers, people who write documentation tend to use words like "should not" and "never" to mean "don't do this unless you really know what you're doing and why".
A couple of my other favorites in the C# world are that they tell you to "never call lock(this)" or "never call GC.Collect()". These two are forcefully declared in many blogs and official documentation, and IMO are complete misinformation. On some level this misinformation serves its purpose, in that it keeps the beginners away from doing things they don't understand before fully researching the alternatives, but at the same time, it makes it difficult to find REAL information via search-engines that all seem to point to articles telling you not to do something while offering no answer to the question "why not?"
Politically, it boils down to what people consider "good design" or "bad design". Official documentation should not be dictating the design of my application. If there's truly a technical reason that you shouldn't call sleep(), then IMO the documentation should state that it is totally okay to call it under specific scenarios, but maybe offer some alternative solutions that are scenario independent or more appropriate for the other scenarios.
Clearly calling "sleep()" is useful in many situations when deadlines are clearly defined in real-world-time terms, however, there are more sophisticated systems for waiting on and signalling threads that should be considered and understood before you start throwing sleep() into your code, and throwing unnecessary sleep() statements in your code is generally considered a beginners' tactic.
I usually get "Attempted to read or write protected memory" when calling the "Show" method on some WinForms. I checked and there doesn't appear anything special about those forms. I don't know why this works (maybe someone can tell me) but usually moving the code that gets executed in the "Load" event of the form to the "Shown" event fixes it for me and I never see it again.
I had this and am mystified as to what has caused it, even after reading the above responses. My solution was to do
git reset --hard origin/master
Then that just resets my (local) copy of master (which I assume is screwed up) to the correct point, as represented by (remote) origin/master.
WARNING: You will lose all changes not yet pushed to

}

Though they are (mostly) identical (see below for the one [bug] difference), you definitely should care and you should use Int32.
The name for a 16-bit integer is Int16. For a 64 bit integer it's Int64, and for a 32-bit integer the intuitive choice is: int or Int32?
The question of the size of a variable of type Int16, Int32, or Int64 is self-referencing, but the question of the size of a variable of type int is a perfectly valid question and questions, no matter how trivial, are distracting, lead to confusion, waste time, hinder discussion, etc. (the fact this question exists proves the point).
Using Int32 promotes that the developer is conscious of their choice of type. How big is an int again? Oh yeah, 32. The likelihood that the size of the type will actually be considered is greater when the size is included in the name. Using Int32 also promotes knowledge of the other choices. When people aren't forced to at least recognize there are alternatives it become far too easy for int to become "THE integer type".
The class within the framework intended to interact with 32-bit integers is named Int32. Once again, which is: more intuitive, less confusing, lacks an (unnecessary) translation (not a translation in the system, but in the mind of the developer), etc. int lMax = Int32.MaxValue
or Int32 lMax = Int32.MaxValue
?
int isn't a keyword in all .NET languages.
Although there are arguments why it's not likely to ever change, int may not always be an Int32.
The drawbacks are two extra characters to type and [bug].
This won't compile
public enum MyEnum : Int32
{
AEnum = 0
}
But this will:
public enum MyEnum : int
{
AEnum = 0
}

I went through all these wonderful answers and realized most of them do not work with iOS 8, or do work but the separator changes size during animation causing unwanted flashing. This is what I ended up doing in my app delegate before creating the window:
[[UITableView appearance] setSeparatorInset:UIEdgeInsetsZero];
[[UITableViewCell appearance] setSeparatorInset:UIEdgeInsetsZero];
if ([UITableView instancesRespondToSelector:@selector(setLayoutMargins:)]) {
[[UITableView appearance] setLayoutMargins:UIEdgeInsetsZero];
[[UITableViewCell appearance] setLayoutMargins:UIEdgeInsetsZero];
[[UITableViewCell appearance] setPreservesSuperviewLayoutMargins:NO];
}
And this is what I added to my UITableViewController:
-(void)viewDidLayoutSubviews
{
[super viewDidLayoutSubviews];
if ([self.tableView respondsToSelector:@selector(setSeparatorInset:)]) {
[self.tableView setSeparatorInset:UIEdgeInsetsZero];
}
if ([self.tableView respondsToSelector:@selector(setLayoutMargins:)]) {
[self.tableView setLayoutMargins:UIEdgeInsetsZero];
}
}
I didn't need to add anything else. Thanks to everyone who provided the crucial bits.
As of NuGet 2.8, there is a feature to downgrade a package.
Example:
The following command entered into the Package Manager Console will downgrade the Couchbase client to version 1.3.1.0.
Update-Package CouchbaseNetClient -Version 1.3.1.0
Result:
Updating 'CouchbaseNetClient' from version '1.3.3' to '1.3.1.0' in project [project name].
Removing 'CouchbaseNetClient 1.3.3' from [project name].
Successfully removed 'CouchbaseNetClient 1.3.3' from [project name].
Something to note as per crimbo below:
This approach doesn't work for downgrading from one prerelease version to other prerelease version - it only works for downgrading to a release version
Regex.Unescape(string) method converts any escaped characters in the input string.
The Unescape method performs one of the following two transformations:
It reverses the transformation performed by the Escape method by removing the escape character ("\") from each character escaped by the method. These include the \, *, +, ?, |, {, [, (,), ^, $, ., #, and white space characters. In addition, the Unescape method unescapes the closing bracket (]) and closing brace (}) characters.
It replaces the hexadecimal values in verbatim string literals with the actual printable characters. For example, it replaces @"\x07" with "\a", or @"\x0A" with "\n". It converts to supported escape characters such as \a, \b, \e, \n, \r, \f, \t, \v, and alphanumeric characters.
string str = @"a\\b\\c";
var output = System.Text.RegularExpressions.Regex.Unescape(str);

Be sure to have a stylesheet assigned for printing.
It could be a separate stylesheet:
<link rel="stylesheet" type="text/css" media="print" href="print.css">
or one you share for all devices:

Then, you can write your styles for printers in the separate stylesheets or in the shared one using media queries:
@media print {
/* Your styles here */
}

By some reason sql server save some identity columns in different tables, the code that work for me, is the following:
select TABLE_NAME tabla,COLUMN_NAME columna
from INFORMATION_SCHEMA.COLUMNS
where COLUMNPROPERTY(object_id(TABLE_SCHEMA+'.'+TABLE_NAME), COLUMN_NAME, 'IsIdentity') = 1
union all
select o.name tabla, c.name columna
from sys.objects o
inner join sys.columns c on o.object_id = c.object_id
where c.is_identity = 1
I do it this way:
SELECT a.* FROM articles AS a
LEFT JOIN articles AS a2
ON a.section = a2.section AND a.article_date <= a2.article_date
GROUP BY a.article_id
HAVING COUNT(*) <= 10;
update: This example of GROUP BY works in MySQL and SQLite only, because those databases are more permissive than standard SQL regarding GROUP BY. Most SQL implementations require that all columns in the select-list that aren't part of an aggregate expression are also in the GROUP BY.
<iframe>
The iframe element represents a nested browsing context. HTML 5 standard - "The
<iframe>
element"
Primarily used to include resources from other domains or subdomains but can be used to include content from the same domain as well. The <iframe>
's strength is that the embedded code is 'live' and can communicate with the parent document.
<embed>
Standardised in HTML 5, before that it was a non standard tag, which admittedly was implemented by all major browsers. Behaviour prior to HTML 5 can vary ...
The embed element provides an integration point for an external (typically non-HTML) application or interactive content. (HTML 5 standard - "The
<embed>
element")
Used to embed content for browser plugins. Exceptions to this is SVG and HTML that are handled differently according to the standard.
The details of what can and can not be done with the embedded content is up to the browser plugin in question. But for SVG you can access the embedded SVG document from the parent with something like:
svg = document.getElementById("parent_id").getSVGDocument();
From inside an embedded SVG or HTML document you can reach the parent with:
parent = window.parent.document;
For embedded HTML there is no way to get at the embedded document from the parent (that I have found).
<object>
The
<object>
element can represent an external resource, which, depending on the type of the resource, will either be treated as an image, as a nested browsing context, or as an external resource to be processed by a plugin. (HTML 5 standard - "The<object>
element")
Unless you are embedding SVG or something static you are probably best of using <iframe>
. To include SVG use <embed>
(if I remember correctly <object>
won't let you script†). Honestly I don't know why you would use <object>
unless for older browsers or flash (that I don't work with).
† As pointed out in the comments below; scripts in <object>
will run but the parent and child contexts can't communicate directly. With <embed>
you can get the context of the child from the parent and vice versa. This means they you can use scripts in the parent to manipulate the child etc. That part is not possible with <object>
or <iframe>
where you would have to set up some other mechanism instead, such as the JavaScript postMessage API.
If you want to access event object as well as data passed, you have to pass event
and ticket.id
both as parameters, like following:
HTML
<input type="number" v-on:input="addToCart($event, ticket.id)" min="0" placeholder="0">
Javascript
methods: {
addToCart: function (event, id) {
// use event here as well as id
console.log('In addToCart')
console.log(id)
}
}
See working fiddle: https://jsfiddle.net/nee5nszL/
In case you are using vue-router, you may have to use $event in your v-on:input
method like following:
<input type="number" v-on:input="addToCart($event, num)" min="0" placeholder="0">
Here is working fiddle.
As of 18/04/2017, no simple black or white list of characters and filenames is evident among the answers to this topic - and there are many replies.
The best suggestion I could come up with was to let the user name the file however he likes. Using an error handler when the application tries to save the file, catch any exceptions, assume the filename is to blame (obviously after making sure the save path was ok as well), and prompt the user for a new file name. For best results, place this checking procedure within a loop that continues until either the user gets it right or gives up. Worked best for me (at least in VBA).
first_line = next(open(filename))

The easiest way to set an environment variable in CentOS is to use export as in
$> export JAVA_HOME=/usr/java/jdk.1.5.0_12
$> export PATH=$PATH:$JAVA_HOME
However, variables set in such a manner are transient i.e. they will disappear the moment you exit the shell. Obviously this is not helpful when setting environment variables that need to persist even when the system reboots.
In such cases, you need to set the variables within the system wide profile. In CentOS (I’m using v5.2), the folder /etc/profile.d/ is the recommended place to add customizations to the system profile.
For example, when installing the Sun JDK, you might need to set the JAVA_HOME and JRE_HOME environment variables. In this case:
Create a new file called java.sh
vim /etc/profile.d/java.sh
Within this file, initialize the necessary environment variables
export JRE_HOME=/usr/java/jdk1.5.0_12/jre
export PATH=$PATH:$JRE_HOME/bin
export JAVA_HOME=/usr/java/jdk1.5.0_12
export JAVA_PATH=$JAVA_HOME
export PATH=$PATH:$JAVA_HOME/bin
Now when you restart your machine, the environment variables within java.sh will be automatically initialized (checkout /etc/profile if you are curious how the files in /etc/profile.d/ are loaded).
PS: If you want to load the environment variables within java.sh
without having to restart the machine, you can use the source command as in:
$> source java.sh
SELECT 'INSERT SomeOtherDB.dbo.table(column1,column2,etc.)
SELECT ' + CONVERT(VARCHAR(12), Pk_Id) + ','
+ '''' + REPLACE(ProductName, '''', '''''') + ''','
+ CONVERT(VARCHAR(12), Fk_CompanyId) + ','
+ CONVERT(VARCHAR(12), Price) + ';'
FROM dbo.unspecified_table_name
WHERE Fk_CompanyId = 1;
For rows you can simply use wc -l file
-l
stands for total line
for columns uou can simply use head -1 file | tr ";" "\n" | wc -l
Explanation
head -1 file
Grabbing the first line of your file, which should be the headers,
and sending to it to the next cmd through the pipe
| tr ";" "\n"
tr
stands for translate.
It will translate all ;
characters into a newline character.
In this example ;
is your delimiter.
Then it sends data to next command.
wc -l
Counts the total number of lines.
In ubuntu to install php_soap
on PHP7 use below commands. Reference
sudo apt-get install php7.0-soap
sudo systemctl restart apache2.service
For older version of php use below command and restart apache.
apt-get install php-soap
Destructors provide an implicit way of freeing unmanaged resources encapsulated in your class, they get called when the GC gets around to it and they implicitly call the Finalize method of the base class. If you're using a lot of unmanaged resources it is better to provide an explicit way of freeing those resources via the IDisposable interface. See the C# programming guide: http://msdn.microsoft.com/en-us/library/66x5fx1b.aspx
this works for me, sudo apt-get install libx11-dev
At CMD
prompt:
>ver
Microsoft Windows [Version 10.0.18362.476]

Although there are clearly numerous reasons for this behavior, several answers point to issues with scaling and screen resolutions. One workaround is to use the following functions to resize and anchor the controls to a specific cell:
Sub ResizeCombo(ByRef cbo As Shape, ByVal rw As Long, ByVal cl As Long, ByVal wid As Long)
cbo.Height = Intake.Cells(rw, cl).Height - 1
cbo.Top = Intake.Cells(rw, cl).Top + 1
cbo.Left = Intake.Cells(rw, cl).Left + 1
cbo.Width = wid
End Sub
Sub ResizeCheckbox(ByRef cbo As Shape, ByVal rw As Long, ByVal cl As Long)
cbo.Height = Intake.Cells(rw, cl).Height - 1
cbo.Top = Intake.Cells(rw, cl).Top + 1
cbo.Left = Intake.Cells(rw, cl).Left + 6
cbo.Width = Intake.Cells(rw, cl).MergeArea.Width - 7
End Sub
Sub ResizeCombos()
ResizeCombo Intake.Shapes("School"), 11, 1, 144
ResizeCheckbox Intake.Shapes("cbReading"), 70, 1
''ResizeCombo also works for option buttons
ResizeCombo Intake.Shapes("obGenderMale"), 20, 8, 45
ResizeCombo Intake.Shapes("obGenderFemale"), 20, 9,50
HOWEVER, recently this workaround stopped working. I've been banging against it for days until I discovered that the zoom level of the sheet had been adjusted to 105%! Resetting it to 100% resolved the problem. However what if the user needs a higher zoom level? I figured out that I can change the zoom after resizing and things stay where they were meant to. My calling function now looks like this:
Sub refresh()
OldZoom = ActiveWindow.Zoom
ActiveWindow.Zoom = 100
Call ResizeCombos
ActiveWindow.Zoom = OldZoom
End Sub
So far it is working!

Given this example url:
http://www.example.com/some-dir/yourpage.php?q=bogus&n=10
$_SERVER['REQUEST_URI']
will give you:
/some-dir/yourpage.php?q=bogus&n=10
Whereas $_GET['q']
will give you:
bogus
In other words, $_SERVER['REQUEST_URI']
will hold the full request path including the querystring. And $_GET['q']
will give you the value of parameter q
in the querystring.
