You should use the ISO-8601 format for string representations of dates - anything else is dependent on the SQL Server language and dateformat settings.
The ISO-8601 format for a DATETIME
when using only the date is: YYYYMMDD
(no dashes or antyhing!)
For a DATETIME
with the time portion, it's YYYY-MM-DDTHH:MM:SS
(with dashes, and a T
in the middle to separate date and time portions).
If you want to convert a string to a DATE
for SQL Server 2008 or newer, you can use YYYY-MM-DD
(with the dashes) to achieve the same result. And don't ask me why this is so inconsistent and confusing - it just is, and you'll have to work with that for now.
So in your case, you should try:
declare @a datetime
declare @b datetime
set @a = '2012-04-06T12:23:45' -- 6th of April, 2012
set @b = '2012-08-06T21:10:12' -- 6th of August, 2012
exec LogProcedure 'AccountLog', N'test', @a, @b
Furthermore - your stored proc has problem, since you're concatenating together datetime
and string into a string, but you're not converting the datetime
to string first, and also, you're forgetting the close quotes in your statement after both dates.
So change this line here to this:
IF @DateFirst <> '' and @DateLast <> ''
SET @FinalSQL = @FinalSQL + ' OR CONVERT(Date, DateLog) >= ''' +
CONVERT(VARCHAR(50), @DateFirst, 126) + -- convert @DateFirst to string for concatenation!
''' AND CONVERT(Date, DateLog) <=''' + -- you need closing quotes after @DateFirst!
CONVERT(VARCHAR(50), @DateLast, 126) + '''' -- convert @DateLast to string and also: closing tags after that missing!
With these settings, and once you've fixed your stored procedure which contains problems right now, it will work.
For the sources on dependency level ( pom.xml) you can add :
<classifier>sources</classifier>
For simulating keyboard events in Chrome:
There is a related bug in webkit that keyboard events when initialized with initKeyboardEvent get an incorrect keyCode and charCode of 0: https://bugs.webkit.org/show_bug.cgi?id=16735
A working solution for it is posted in this SO answer.
If you have only one type of collections (e.g. scatter with no error bars) you can also change the colours after that you have plotted them, this sometimes is easier to perform.
import matplotlib.pyplot as plt
from random import randint
import numpy as np
#Let's generate some random X, Y data X = [ [frst group],[second group] ...]
X = [ [randint(0,50) for i in range(0,5)] for i in range(0,24)]
Y = [ [randint(0,50) for i in range(0,5)] for i in range(0,24)]
labels = range(1,len(X)+1)
fig = plt.figure()
ax = fig.add_subplot(111)
for x,y,lab in zip(X,Y,labels):
ax.scatter(x,y,label=lab)
#Now this is actually the code that you need, an easy fix your colors just cut and paste not you need ax.
colormap = plt.cm.gist_ncar #nipy_spectral, Set1,Paired
colorst = [colormap(i) for i in np.linspace(0, 0.9,len(ax.collections))]
for t,j1 in enumerate(ax.collections):
j1.set_color(colorst[t])
ax.legend(fontsize='small')
The output gives you differnent colors even when you have many different scatter plots in the same subplot.
I got here for the same problem, but for a different reason:
Class.objects.get(id=1)
This code was raising an ImportError exception. What was confusing me was that the code below executed fine and returned a result set as expected:
Class.objects.all()
Tail of the traceback for the get()
method:
File "django/db/models/loading.py", line 197, in get_models
self._populate()
File "django/db/models/loading.py", line 72, in _populate
self.load_app(app_name, True)
File "django/db/models/loading.py", line 94, in load_app
app_module = import_module(app_name)
File "django/utils/importlib.py", line 35, in import_module
__import__(name)
ImportError: No module named myapp
Reading the code inside Django's loading.py
, I came to the conclusion that my settings.py
had a bad path to my app which contains my Class
model definition. All I had to do was correct the path to the app and the get()
method executed fine.
Here is my settings.py
with the corrected path:
INSTALLED_APPS = (
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
# ...
'mywebproject.myapp',
)
All the confusion was caused because I am using Django's ORM as a standalone, so the namespace had to reflect that.
From a blog on running sample variance calculations, where the mean is also calculated using Welford's method:
Too bad we can't upload SVG images.
Use DATE()
function:
select * from follow_queue group by DATE(follow_date)
I know its late but here is my thought you might wanna consider.
for example this is array
{
m,m,m
a,a,a
b,b,b
j,j,j
k,l,m
}
and you want to convert it by column number 2, then
string[] newArr = new string[arr.length]
for(int a=0;a<arr.length;a++)
newArr[a] = arr[a][1] + a;
// create new array that contains index number at the end and also the column values
Array.Sort(newArr);
for(int a=0;a<newArr.length;a++)
{
int index = Convert.ToInt32(newArr[a][newArr[a].Length -1]);
//swap whole row with tow at current index
if(index != a)
{
string[] arr2 = arr[a];
arr[a] = arr[index];
arr[index] = arr2;
}
}
Congratulations you have sorted the array by desired column. You can edit this to make it work with other data types
The following code has worked for me. This code will print date in DD-MM-YYYY format.
DateValue=DateValue.substring(6,8)+"-"+DateValue.substring(4,6)+"-"+DateValue.substring(0,4);
else, you can also use:
DateValue=DateValue.substring(0,4)+"-"+DateValue.substring(4,6)+"-"+DateValue.substring(6,8);
From the docs ...
A string containing "\r\n" for non-Unix platforms, or a string containing "\n" for Unix platforms.
There are many ideas, initially I am pondering on these two:
pip
cons: not always installed
help('modules')
cons: output to console; with broken modules (see ubuntu...) can segfault
I need an easy approach, using basic libraries and compatible with old python 2.x
And I see the light: listmodules.py
Hidden in the documentation source directory in 2.5 is a small script that lists all available modules for a Python installation.
Pros:
uses only imp, sys, os, re, time
designed to run on Python 1.5.2 and newer
the source code is really compact, so you can easy tinkering with it, for example to pass an exception list of buggy modules (don't try to import them)
@JoinColumn
could be used on both sides of the relationship. The question was about using @JoinColumn
on the @OneToMany
side (rare case). And the point here is in physical information duplication (column name) along with not optimized SQL query that will produce some additional UPDATE
statements.
According to documentation:
Since many to one are (almost) always the owner side of a bidirectional relationship in the JPA spec, the one to many association is annotated by @OneToMany(mappedBy=...)
@Entity
public class Troop {
@OneToMany(mappedBy="troop")
public Set<Soldier> getSoldiers() {
...
}
@Entity
public class Soldier {
@ManyToOne
@JoinColumn(name="troop_fk")
public Troop getTroop() {
...
}
Troop
has a bidirectional one to many relationship with Soldier
through the troop property. You don't have to (must not) define any physical mapping in the mappedBy
side.
To map a bidirectional one to many, with the one-to-many side as the owning side, you have to remove the mappedBy
element and set the many to one @JoinColumn
as insertable
and updatable
to false. This solution is not optimized and will produce some additional UPDATE
statements.
@Entity
public class Troop {
@OneToMany
@JoinColumn(name="troop_fk") //we need to duplicate the physical information
public Set<Soldier> getSoldiers() {
...
}
@Entity
public class Soldier {
@ManyToOne
@JoinColumn(name="troop_fk", insertable=false, updatable=false)
public Troop getTroop() {
...
}
See this example :
<?php
echo "<div id='div1'>text</div>"
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title></title>
<script src="js/jquery1.3.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$('#div1').click(function () {
alert('I clicked');
});
});
</script>
</head>
<body>
</body>
</html>
If you don't want to get involved with locales here is a function that formats numbers:
def int_format(value, decimal_points=3, seperator=u'.'):
value = str(value)
if len(value) <= decimal_points:
return value
# say here we have value = '12345' and the default params above
parts = []
while value:
parts.append(value[-decimal_points:])
value = value[:-decimal_points]
# now we should have parts = ['345', '12']
parts.reverse()
# and the return value should be u'12.345'
return seperator.join(parts)
Creating a custom template filter from this function is trivial.
The benefit of not calling via the shell is that you are not invoking a 'mystery program.' On POSIX, the environment variable SHELL
controls which binary is invoked as the "shell." On Windows, there is no bourne shell descendent, only cmd.exe.
So invoking the shell invokes a program of the user's choosing and is platform-dependent. Generally speaking, avoid invocations via the shell.
Invoking via the shell does allow you to expand environment variables and file globs according to the shell's usual mechanism. On POSIX systems, the shell expands file globs to a list of files. On Windows, a file glob (e.g., "*.*") is not expanded by the shell, anyway (but environment variables on a command line are expanded by cmd.exe).
If you think you want environment variable expansions and file globs, research the ILS
attacks of 1992-ish on network services which performed subprogram invocations via the shell. Examples include the various sendmail
backdoors involving ILS
.
In summary, use shell=False
.
@Esteban Küber is absolutely right.
Maybe one additional hint for bloody beginners like me. If you speciify the variables with %s, you have to follow this principle for EVERY input value, which means for the SET-variables as well as for the WHERE-variables.
Otherwise, you will have to face a termination message like 'You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '%s WHERE'
alert()
doesn't support HTML, but you have some alternatives to format your message.
You can use Unicode characters as others stated, or you can make use of the ES6 Template literals. For example:
...
.catch(function (error) {
const alertMessage = `Error retrieving resource. Please make sure:
• the resource server is accessible
• you're logged in
Error: ${error}`;
window.alert(alertMessage);
}
As you can see, it maintains the line breaks and spaces that we included in the variable, with no extra characters.
If column is not NOT NULL
(nullable).
You just put NULL
instead of value in INSERT
statement.
You Can easily Convert columns to VARBINARY(Max Length), The length must be the maximum you expect to avoid defective comparison, It's enough to set length as the column length. Trim column help you to compare the real value except space has a meaning and valued in your table columns, This is a simple sample and as you can see I Trim the columns value and then convert and compare.:
CONVERT(VARBINARY(250),LTRIM(RTRIM(Column1))) = CONVERT(VARBINARY(250),LTRIM(RTRIM(Column2)))
Hope this help.

Your code is almost right! You are right, you are just missing one step. When you read in the file, you are reading it as a string; but you want to turn the string back into a dictionary.
The error message you saw was because self.whip
was a string, not a dictionary.
I first wrote that you could just feed the string into dict()
but that doesn't work! You need to do something else.
Here is the simplest way: feed the string into eval()
. Like so:
def reading(self):
s = open('deed.txt', 'r').read()
self.whip = eval(s)
You can do it in one line, but I think it looks messy this way:
def reading(self):
self.whip = eval(open('deed.txt', 'r').read())
But eval()
is sometimes not recommended. The problem is that eval()
will evaluate any string, and if someone tricked you into running a really tricky string, something bad might happen. In this case, you are just running eval()
on your own file, so it should be okay.
But because eval()
is useful, someone made an alternative to it that is safer. This is called literal_eval
and you get it from a Python module called ast
.
import ast
def reading(self):
s = open('deed.txt', 'r').read()
self.whip = ast.literal_eval(s)
ast.literal_eval()
will only evaluate strings that turn into the basic Python types, so there is no way that a tricky string can do something bad on your computer.
Actually, best practice in Python is to use a with
statement to make sure the file gets properly closed. Rewriting the above to use a with
statement:
import ast
def reading(self):
with open('deed.txt', 'r') as f:
s = f.read()
self.whip = ast.literal_eval(s)
In the most popular Python, known as "CPython", you usually don't need the with
statement as the built-in "garbage collection" features will figure out that you are done with the file and will close it for you. But other Python implementations, like "Jython" (Python for the Java VM) or "PyPy" (a really cool experimental system with just-in-time code optimization) might not figure out to close the file for you. It's good to get in the habit of using with
, and I think it makes the code pretty easy to understand.
You can use both !=
or <>
.
However, note that !=
is preferred where <>
is deprecated.
I ended up using the bootstrap 3 dropdown button, I'm posting my solution here in case it helps someone in future. Adding the bootstrap 3 list-inline to the class for the ul causes it to display in a nicely compact format as well.
<div class="btn-group">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">
Select icon <span class="caret"></span>
</button>
<ul class="dropdown-menu list-inline" role="menu">
<li><span class="glyphicon glyphicon-cutlery"></span></li>
<li><span class="glyphicon glyphicon-fire"></span></li>
<li><span class="glyphicon glyphicon-glass"></span></li>
<li><span class="glyphicon glyphicon-heart"></span></li>
</ul>
</div>
I'm using Angular.js so this is the actual code I used:
<div class="btn-group">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">
Avatar <span class="caret"></span>
</button>
<ul class="dropdown-menu list-inline" role="menu">
<li ng-repeat="avatar in avatars" ng-click="avatarSelected(avatar)">
<span ng-class="getAvatar(avatar)"></span>
</li>
</ul>
</div>
And in my controller:
$scope.avatars=['cutlery','eye-open','flag','flash','glass','fire','hand-right','heart','heart-empty','leaf','music','send','star','star-empty','tint','tower','tree-conifer','tree-deciduous','usd','user','wrench','time','road','cloud'];
$scope.getAvatar=function(avatar){
return 'glyphicon glyphicon-'+avatar;
};
Hello I can suggest you universal method. use recursion.
public static JSONObject function(JSONObject obj, String keyMain,String valueMain, String newValue) throws Exception {
// We need to know keys of Jsonobject
JSONObject json = new JSONObject()
Iterator iterator = obj.keys();
String key = null;
while (iterator.hasNext()) {
key = (String) iterator.next();
// if object is just string we change value in key
if ((obj.optJSONArray(key)==null) && (obj.optJSONObject(key)==null)) {
if ((key.equals(keyMain)) && (obj.get(key).toString().equals(valueMain))) {
// put new value
obj.put(key, newValue);
return obj;
}
}
// if it's jsonobject
if (obj.optJSONObject(key) != null) {
function(obj.getJSONObject(key), keyMain, valueMain, newValue);
}
// if it's jsonarray
if (obj.optJSONArray(key) != null) {
JSONArray jArray = obj.getJSONArray(key);
for (int i=0;i<jArray.length();i++) {
function(jArray.getJSONObject(i), keyMain, valueMain, newValue);
}
}
}
return obj;
}
It should work. If you have questions, go ahead.. I'm ready.
You can use Jquery's on method and listen for the scroll

Not all closures are lambdas and not all lambdas are closures. Both are functions, but not necessarily in the manner we're used to knowing.
A lambda is essentially a function that is defined inline rather than the standard method of declaring functions. Lambdas can frequently be passed around as objects.
A closure is a function that encloses its surrounding state by referencing fields external to its body. The enclosed state remains across invocations of the closure.
In an object-oriented language, closures are normally provided through objects. However, some OO languages (e.g. C#) implement special functionality that is closer to the definition of closures provided by purely functional languages (such as lisp) that do not have objects to enclose state.
What's interesting is that the introduction of Lambdas and Closures in C# brings functional programming closer to mainstream usage.
I tried above answers and they didn't help in my case.
I solved it with this link help: http://vjscrazzy.blogspot.co.il/2016/02/failed-to-sync-gradle-project.html

After that, I did these changes(because it still wrote me some other errors)
Android Studio asked me:

Also, if your working in a team with repositories, it's important to check that the version of the Andorid Studio is the same.
The most direct way to get a list of columns of certain dtype e.g. 'object':
df.select_dtypes(include='object').columns
For example:
>>df = pd.DataFrame([[1, 2.3456, 'c', 'd', 78]], columns=list("ABCDE"))
>>df.dtypes
A int64
B float64
C object
D object
E int64
dtype: object
To get all 'object' dtype columns:
>>df.select_dtypes(include='object').columns
Index(['C', 'D'], dtype='object')
For just the list:
>>list(df.select_dtypes(include='object').columns)
['C', 'D']
curl https://bootstrap.pypa.io/get-pip.py | python3.4
Or if you don't have curl
for some reason:
wget https://bootstrap.pypa.io/get-pip.py
python3.4 get-pip.py
After this you should be able to run
$ pip3
You didn't close your ; after position: absolute. Otherwise your above code would have worked perfectly!
#footer {
position:absolute;
bottom:30px;
width:100%;
}
One thing that i do is df=df.reset_index()
then df=df.drop(['index'],axis=1)
Note however:
If you issue SET TRANSACTION ISOLATION LEVEL in a stored procedure or trigger, when the object returns control the isolation level is reset to the level in effect when the object was invoked. For example, if you set REPEATABLE READ in a batch, and the batch then calls a stored procedure that sets the isolation level to SERIALIZABLE, the isolation level setting reverts to REPEATABLE READ when the stored procedure returns control to the batch.

I came across this thread while working on my understanding of Cython. My extension to the original question might be of use to others working at the C / Cython interface. So this is the extension of the original question: how do I return a string from a C function, making it available to Cython & thus to Python?
For those not familiar with it, Cython allows you to statically type Python code that you need to speed up. So the process is, enjoy writing Python :), find its a bit slow somewhere, profile it, calve off a function or two and cythonize them. Wow. Close to C speed (it compiles to C) Fixed. Yay. The other use is importing C functions or libraries into Python as done here.
This will print a string and return the same or another string to Python. There are 3 files, the c file c_hello.c, the cython file sayhello.pyx, and the cython setup file sayhello.pyx. When they are compiled using python setup.py build_ext --inplace
they generate a shared library file that can be imported into python or ipython and the function sayhello.hello run.
c_hello.c
#include <stdio.h>
char *c_hello() {
char *mystr = "Hello World!\n";
return mystr;
// return "this string"; // alterative
}
sayhello.pyx
cdef extern from "c_hello.c":
cdef char* c_hello()
def hello():
return c_hello()
setup.py
from setuptools import setup
from setuptools.extension import Extension
from Cython.Distutils import build_ext
from Cython.Build import cythonize
ext_modules = cythonize([Extension("sayhello", ["sayhello.pyx"])])
setup(
name = 'Hello world app',
cmdclass = {'build_ext': build_ext},
ext_modules = ext_modules
)

Another use-case where nameof
feature of C# 6.0 becomes handy - Consider a library like Dapper which makes DB retrievals much easier. Albeit this is a great library, you need to hardcode property/field names within query. What this means is that if you decide to rename your property/field, there are high chances that you will forget to update query to use new field names. With string interpolation and nameof
features, code becomes much easier to maintain and typesafe.
From the example given in link
without nameof
var dog = connection.Query<Dog>("select Age = @Age, Id = @Id", new { Age = (int?)null, Id = guid });
with nameof
var dog = connection.Query<Dog>($"select {nameof(Dog.Age)} = @Age, {nameof(Dog.Id)} = @Id", new { Age = (int?)null, Id = guid });
On some apps you need to remove the slashes to make it work.

This bug seems to be somewhat of a separate issue than the standard separate stacking context IE bug. I had a similar issue with multiple stacked inputs (essentially a table with an autocompleter in each row). The only solution I found was to give each cell a decreasing z-index value.

I agree with Thomas and I would choose the DECIMAL(5,4) solution at least for WPF applications.
Have a look to the MSDN Numeric Format String to know why : http://msdn.microsoft.com/en-us/library/dwhawy9k#PFormatString
The percent ("P") format specifier multiplies a number by 100 and converts it to a string that represents a percentage.
Then you would be able to use this in your XAML code:
DataFormatString="{}{0:P}"
We will import the CSV file into the destination table in the simplest form. I placed my sample CSV file on the C: drive and now we will create a table which we will import data from the CSV file.
DROP TABLE IF EXISTS Sales

In the case of CROSS ORIGIN request read this:
I faced this situation and at first I chose to use the Authorization
Header and later removed it after facing the following issue.
Authorization
Header is considered a custom header. So if a cross-domain request is made with the Autorization
Header set, the browser first sends a preflight request. A preflight request is an HTTP request by the OPTIONS method, this request strips all the parameters from the request. Your server needs to respond with Access-Control-Allow-Headers
Header having the value of your custom header (Authorization
header).
So for each request the client (browser) sends, an additional HTTP request(OPTIONS) was being sent by the browser. This deteriorated the performance of my API. You should check if adding this degrades your performance. As a workaround I am sending tokens in http parameters, which I know is not the best way of doing it but I couldn't compromise with the performance.
If key
isn't an int
or float
but a str
ing, you need to convert it to an int
first by doing
key = int(key)
or to a float
by doing
key = float(key)
Otherwise, what you have in your question should work, but
if (key < 1) or (key > 34):
or
if not (1 <= key <= 34):
would be a bit clearer.
I don't know if this is still relevant. But when I had similar issue this is how I resolved it.
Where you need to clear an uncontrolled form you simply do this after submission.
this.<ref-name-goes-here>.setState({value: ''});
Hope this helps.
Use keypress
event on usersSearch
textbox and look for Enter button. If enter button is pressed then trigger the search button click event which will do the rest of work. Try this.
$('document').ready(function(){
$('#searchButton').click(function(){
var search = $('#usersSearch').val();
$.post('../searchusers.php',{search: search},function(response){
$('#userSearchResultsTable').html(response);
});
})
$('#usersSearch').keypress(function(e){
if(e.which == 13){//Enter key pressed
$('#searchButton').click();//Trigger search button click event
}
});
});
You can use Programmatic Navigation.In order to go back, you use this:
router.go(n)
Where n can be positive or negative (to go back). This is the same as history.back().So you can have your element like this:
<a @click="$router.go(-1)">back</a>
\n is the line break used by Unix(-like) systems, \r\n is used by windows. This has nothing to do with C#.
Yeah.... i kinda see what you need. I just came across same problem.
Here is exactly what i did. Now, bear in mind, this some low level knowledge, since i'm just starting. I made my life complicated, so i needed solution. I kinda found it on my own, using different directions from above answers.
I switched from win 10 on HDD to linux on SSD, so i needed my few of .class and .java imported into new workspace.
First i made a mistake, not using export option on windows and i just simply copied all of files from src and bin folders on win 10 to src and bin folders on linux. Of course workspace did not see those files.
Solution was found in IMPORT tool (which i should have used right away).
I put all of files in src folder into zipp file, and moved this file to some arbitrary folder (Home folder in my case).
Go back to src folder and delete all of .java files (you won't be needing them anymore).
Then i opened my empty project and selected import from File menu in Eclipse. In import window, under option General (first one) select Import Archive.
Now simply find your zip file, and Voila! All is where it should be.
You dont need jquery-migrate. Summarizing previous answers, here is a working html:
<html>
<body>
<a id='linkButton'>ClickMe</a>
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<link href="https://cdnjs.cloudflare.com/ajax/libs/toastr.js/2.0.1/css/toastr.css" rel="stylesheet"/>
<script src="https://cdnjs.cloudflare.com/ajax/libs/toastr.js/2.0.1/js/toastr.js"></script>
<script type="text/javascript">
$(document).ready(function() {
toastr.options.timeOut = 1500; // 1.5s
toastr.info('Page Loaded!');
$('#linkButton').click(function() {
toastr.success('Click Button');
});
});
</script>
</body>
</html>
AStyle can be customized in great detail for C++ and Java (and others too)
This is a source code formatting tool.
clang-format is a powerful command line tool bundled with the clang compiler which handles even the most obscure language constructs in a coherent way.
It can be integrated with Visual Studio, Emacs, Vim (and others) and can format just the selected lines (or with git/svn to format some diff).
It can be configured with a variety of options listed here.
When using config files (named .clang-format
) styles can be per directory - the closest such file in parent directories shall be used for a particular file.
Styles can be inherited from a preset (say LLVM or Google) and can later override different options
It is used by Google and others and is production ready.
Also look at the project UniversalIndentGUI. You can experiment with several indenters using it: AStyle, Uncrustify, GreatCode, ... and select the best for you. Any of them can be run later from a command line.
Uncrustify has a lot of configurable options. You'll probably need Universal Indent GUI (in Konstantin's reply) as well to configure it.
PdfToImageServlet using ImageMagick's convert
command.
Usage example:
<img src='/webAppDirectory/PdfToImageServlet?pdfFile=/usr/share/cups/data/default-testpage.pdf'>
EDIT: Old answer erased in response to updated question.
You just store the string in a variable:
separator = "!" * int(raw_input("Enter number: "))
print separator
do_stuff()
print separator
other_stuff()
print separator
If it is just about the color and there is no specific need for JavaScript, you could also convert them to a font. This link gives you an opportunity to create a font based on the SVG. However, it is not possible to use img attributes afterwards - like "alt". This also limits the accessibility of your website for blind people and so on.
Sorry, JS code...
Tested with the two inputs:
a = [55,11,66,77,72];
a = [ 0, 12, 13, 4, 5, 32, 8 ];
var first = Number.MIN_VALUE;
var second = Number.MIN_VALUE;
for (var i = -1, len = a.length; ++i < len;) {
var dist = a[i];
// get the largest 2
if (dist > first) {
second = first;
first = dist;
} else if (dist > second) { // && dist < first) { // this is actually not needed, I believe
second = dist;
}
}
console.log('largest, second largest',first,second);
largest, second largest 32 13
This should have a maximum of a.length*2 comparisons and only goes through the list once.
It is possible to use a handler to do this, even in MVC4. Here's an example from one i made earlier:
public class ImageHandler : IHttpHandler
{
byte[] bytes;
public void ProcessRequest(HttpContext context)
{
int param;
if (int.TryParse(context.Request.QueryString["id"], out param))
{
using (var db = new MusicLibContext())
{
if (param == -1)
{
bytes = File.ReadAllBytes(HttpContext.Current.Server.MapPath("~/Images/add.png"));
context.Response.ContentType = "image/png";
}
else
{
var data = (from x in db.Images
where x.ImageID == (short)param
select x).FirstOrDefault();
bytes = data.ImageData;
context.Response.ContentType = "image/" + data.ImageFileType;
}
context.Response.Cache.SetCacheability(HttpCacheability.NoCache);
context.Response.BinaryWrite(bytes);
context.Response.Flush();
context.Response.End();
}
}
else
{
//image not found
}
}
public bool IsReusable
{
get
{
return false;
}
}
}
In the view, i added the ID of the photo to the query string of the handler.
Edit 2018-02-06: revision based on this comment
Edit: forgot to mention that this works on Python 2.7.x
There's multiprocesing.pool, and the following sample illustrates how to use one of them:
from multiprocessing.pool import ThreadPool as Pool
# from multiprocessing import Pool
pool_size = 5 # your "parallelness"
# define worker function before a Pool is instantiated
def worker(item):
try:
api.my_operation(item)
except:
print('error with item')
pool = Pool(pool_size)
for item in items:
pool.apply_async(worker, (item,))
pool.close()
pool.join()
Now if you indeed identify that your process is CPU bound as @abarnert mentioned, change ThreadPool to the process pool implementation (commented under ThreadPool import). You can find more details here: http://docs.python.org/2/library/multiprocessing.html#using-a-pool-of-workers
Wikipedia points to the term Canonicalization.
A process for converting data that has more than one possible representation into a "standard" canonical representation. This can be done to compare different representations for equivalence, to count the number of distinct data structures, to improve the efficiency of various algorithms by eliminating repeated calculations, or to make it possible to impose a meaningful sorting order.
The Unicode example made the most sense to me:
Variable-length encodings in the Unicode standard, in particular UTF-8, have more than one possible encoding for most common characters. This makes string validation more complicated, since every possible encoding of each string character must be considered. A software implementation which does not consider all character encodings runs the risk of accepting strings considered invalid in the application design, which could cause bugs or allow attacks. The solution is to allow a single encoding for each character. Canonicalization is then the process of translating every string character to its single allowed encoding. An alternative is for software to determine whether a string is canonicalized, and then reject it if it is not. In this case, in a client/server context, the canonicalization would be the responsibility of the client.
In summary, a standard form of representation for data. From this form you can then convert to any representation you may need.
1. Performance:
Assume your where clause is like this:
WHERE NAME='JON'
If the NAME column is of any type other than nvarchar or nchar, then you should not specify the N prefix. However, if the NAME column is of type nvarchar or nchar, then if you do not specify the N prefix, then 'JON' is treated as non-unicode. This means the data type of NAME column and string 'JON' are different and so SQL Server implicitly converts one operand’s type to the other. If the SQL Server converts the literal’s type to the column’s type then there is no issue, but if it does the other way then performance will get hurt because the column's index (if available) wont be used.
2. Character set:
If the column is of type nvarchar or nchar, then always use the prefix N while specifying the character string in the WHERE criteria/UPDATE/INSERT clause. If you do not do this and one of the characters in your string is unicode (like international characters - example - a) then it will fail or suffer data corruption.
You can always refer to resources in your application directly by their JNDI name as configured in the container, but if you do so, essentially you are wiring the container-specific name into your code. This has some disadvantages, for example, if you'll ever want to change the name later for some reason, you'll need to update all the references in all your applications, and then rebuild and redeploy them.
<resource-ref>
introduces another layer of indirection: you specify the name you want to use in the web.xml, and, depending on the container, provide a binding in a container-specific configuration file.
So here's what happens: let's say you want to lookup the java:comp/env/jdbc/primaryDB
name. The container finds that web.xml has a <resource-ref>
element for jdbc/primaryDB
, so it will look into the container-specific configuration, that contains something similar to the following:
<resource-ref>
<res-ref-name>jdbc/primaryDB</res-ref-name>
<jndi-name>jdbc/PrimaryDBInTheContainer</jndi-name>
</resource-ref>
Finally, it returns the object registered under the name of jdbc/PrimaryDBInTheContainer
.
The idea is that specifying resources in the web.xml has the advantage of separating the developer role from the deployer role. In other words, as a developer, you don't have to know what your required resources are actually called in production, and as the guy deploying the application, you will have a nice list of names to map to real resources.
You can always count the collection. For example $mentor->intern->count()
will return how many intern does a mentor have.
https://laravel.com/docs/5.2/collections#method-count
In your code you can do something like this
foreach($mentors as $mentor)
@if($mentor->intern->count() > 0)
@foreach($mentor->intern as $intern)
<tr class="table-row-link" data-href="/werknemer/{!! $intern->employee->EmployeeId !!}">
<td>{{ $intern->employee->FirstName }}</td>
<td>{{ $intern->employee->LastName }}</td>
</tr>
@endforeach
@else
Mentor don't have any intern
@endif
@endforeach
If the file input name
indicates an array and flags multiple
, and you parse the entire form
with FormData
, it is not necessary to iteratively append()
the input files. FormData
will automatically handle multiple files.
$('#submit_1').on('click', function() {_x000D_
let data = new FormData($("#my_form")[0]);_x000D_
_x000D_
$.ajax({_x000D_
url: '/path/to/php_file',_x000D_
type: 'POST',_x000D_
data: data,_x000D_
processData: false,_x000D_
contentType: false,_x000D_
success: function(r) {_x000D_
console.log('success', r);_x000D_
},_x000D_
error: function(r) {_x000D_
console.log('error', r);_x000D_
}_x000D_
});_x000D_
});
_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<form id="my_form">_x000D_
<input type="file" name="multi_img_file[]" id="multi_img_file" accept=".gif,.jpg,.jpeg,.png,.svg" multiple="multiple" />_x000D_
<button type="button" name="submit_1" id="submit_1">Not type='submit'</button>_x000D_
</form>
_x000D_
Note that a regular button type="button"
is used, not type="submit"
. This shows there is no dependency on using submit
to get this functionality.
The resulting $_FILES
entry is like this in Chrome dev tools:
multi_img_file:
error: (2) [0, 0]
name: (2) ["pic1.jpg", "pic2.jpg"]
size: (2) [1978036, 2446180]
tmp_name: (2) ["/tmp/phphnrdPz", "/tmp/phpBrGSZN"]
type: (2) ["image/jpeg", "image/jpeg"]
Note: There are cases where some images will upload just fine when uploaded as a single file, but they will fail when uploaded in a set of multiple files. The symptom is that PHP reports empty $_POST
and $_FILES
without AJAX throwing any errors. Issue occurs with Chrome 75.0.3770.100 and PHP 7.0. Only seems to happen with 1 out of several dozen images in my test set.
In my case
li {
list-style-type : none;
}
It doesn't show the bullet but leaved some space for the bullet.
I use
li {
list-style-type : '';
}
It works perfectly.
Runtime#totalMemory - the memory that the JVM has allocated thus far. This isn't necessarily what is in use or the maximum.
Runtime#maxMemory - the maximum amount of memory that the JVM has been configured to use. Once your process reaches this amount, the JVM will not allocate more and instead GC much more frequently.
Runtime#freeMemory - I'm not sure if this is measured from the max or the portion of the total that is unused. I am guessing it is a measurement of the portion of total which is unused.
Use map.panTo();
does not do anything if the point is in the current view. Use map.setView()
instead.
I had a polyline and I had to center map to a new point in polyline at every second. Check the code : GOOD: https://jsfiddle.net/nstudor/xcmdwfjk/
mymap.setView(point, 11, { animation: true });
BAD: https://jsfiddle.net/nstudor/Lgahv905/
mymap.panTo(point);
mymap.setZoom(11);
Negative numbers mean that you count from the right instead of the left. So, list[-1]
refers to the last element, list[-2]
is the second-last, and so on.
3 years later and not a single person has answered this question completely.
The asker wants to cancel the default form submission and call their own Ajax. This is a simple request with a simple solution. There is no need to intercept every character entered into each input.
Assuming the form has a submit button, whether a <button id="save-form">
or an <input id="save-form" type="submit">
, do:
$("#save-form").on("click", function () {
$.ajax({
...
});
return false;
});
Just wanted to add, you can use System.arraycopy
too:
import static java.lang.System.out;
import static java.lang.System.arraycopy;
import java.lang.reflect.Array;
class Playground {
@SuppressWarnings("unchecked")
public static <T>T[] combineArrays(T[] a1, T[] a2) {
T[] result = (T[]) Array.newInstance(a1.getClass().getComponentType(), a1.length+a2.length);
arraycopy(a1,0,result,0,a1.length);
arraycopy(a2,0,result,a1.length,a2.length);
return result;
}
public static void main(String[ ] args) {
String monthsString = "JANFEBMARAPRMAYJUNJULAUGSEPOCTNOVDEC";
String[] months = monthsString.split("(?<=\\G.{3})");
String daysString = "SUNMONTUEWEDTHUFRISAT";
String[] days = daysString.split("(?<=\\G.{3})");
for (String m : months) {
out.println(m);
}
out.println("===");
for (String d : days) {
out.println(d);
}
out.println("===");
String[] results = combineArrays(months, days);
for (String r : results) {
out.println(r);
}
out.println("===");
}
}
use nssm the best solution for windows, just download nssm, open cmd to nssm directory and type
nssm install <service name> <node path> <app.js path>
eg: nssm install myservice "C:\Program Files\nodejs" "C:\myapp\app.js"
this will install a new windows service which will be listed at services.msc from there you can start or stop the service, this service will auto start and you can configure to restart if it fails.
Google's (bad) approach, from HN thread. Store RLE-style counts.
Your initial data structure is '99999999:0' (all zeros, haven't seen any numbers) and then lets say you see the number 3,866,344 so your data structure becomes '3866343:0,1:1,96133654:0' as you can see the numbers will always alternate between number of zero bits and number of '1' bits so you can just assume the odd numbers represent 0 bits and the even numbers 1 bits. This becomes (3866343,1,96133654)
Their problem doesn't seem to cover duplicates, but let's say they use "0:1" for duplicates.
Big problem #1: insertions for 1M integers would take ages.
Big problem #2: like all plain delta encoding solutions, some distributions can't be covered this way. For example, 1m integers with distances 0:99 (e.g. +99 each one). Now think the same but with random distance in the range of 0:99. (Note: 99999999/1000000 = 99.99)
Google's approach is both unworthy (slow) and incorrect. But to their defense, their problem might have been slightly different.
Without using connect by or regexp:

)
,x as (
select name

,','||error||',' error
from mytable
)
,iter as (SELECT rownum AS pos
FROM all_objects
)
select x.name,x.project
,SUBSTR(x.error
,INSTR(x.error, ',', 1, iter.pos) + 1
,INSTR(x.error, ',', 1, iter.pos + 1)-INSTR(x.error, ',', 1, iter.pos)-1
) error
from x, iter
where iter.pos < = (LENGTH(x.error) - LENGTH(REPLACE(x.error, ','))) - 1;
Edited: The
woocommerce_get_product_terms
is deprecated since Woocommerce version 3
Go with the following as @datafeedr wrote in his answer:
global $product;
$koostis = array_shift( wc_get_product_terms( $product->id, 'pa_koostis', array( 'fields' => 'names' ) ) );
or even more compact:
global $product;
$koostis = $product->get_attribute( 'pa_koostis' );
Original answer:
$result = array_shift(woocommerce_get_product_terms($product->id, 'pa_koostis', 'names'));
What I see in this case is that if I pull the client machine's network cable and make the call, the ajax success handler is called (why, I don't know), and the data parameter is an empty string. So if you factor out the real error handling, you can do something like this:
function handleError(jqXHR, textStatus, errorThrown) {
...
}
jQuery.ajax({
...
success: function(data, textStatus, jqXHR) {
if (data == "") handleError(jqXHR, "clientNetworkError", "");
},
error: handleError
});
You may use the following code to remove non-English letters:
import re
str = "123456790 ABC#%? .(???)"
result = re.sub(r'[^\x00-\x7f]',r'', str)
print(result)
This will return
123456790 ABC#%? .()
In Window in new version you can export like this
Ensure position
is on your element and set the z-index
to a value higher than the elements you want to cover.
element {
position: fixed;
z-index: 999;
}
div {
position: relative;
z-index: 99;
}
It will probably require some more work than that but it's a start since you didn't post any code.
According to datatables.net the proper way to do this is adding the lengthMenu property with an array of values.
$(document).ready(function() {
$('#example').dataTable( {
"lengthMenu": [[10, 25, 50, -1], [10, 25, 50, "All"]]
} );
} );
Main Example
The example below will run myfile.sql on database mydatabase using schema myschema.
psql "dbname=mydatabase options=--search_path=myschema" -a -f myfile.sql
The way this works is the first argument to the psql command is the dbname argument. The docs mention a connection string can be provided.
If this parameter contains an = sign or starts with a valid URI prefix (postgresql:// or postgres://), it is treated as a conninfo string
The dbname keyword specifies the database to connect to and the options keyword lets you specify command-line options to send to the server at connection startup. Those options are detailed in the server configuration chapter. The option we are using to select the schema is search_path.
Another Example
The example below will connect to host myhost on database mydatabase using schema myschema. The =
special character must be url escaped with the escape sequence %3D
.
psql postgres://myuser@myhost?options=--search_path%3Dmyschema
If someone is interested in the similar problem, but is not working with XAML, here's my solution:
var B1 = new Border();
B1.BorderBrush = Brushes.Black;
B1.BorderThickness = new Thickness(0, 1, 0, 0); // You can specify here which borders do you want
YourPanel.Children.Add(B1);
^\d{1,2}[\W_]?po$
\d
defines a number and {1,2}
means 1 or two of the expression before, \W
defines a non word character.
Instead use window.open()
:
The syntax is:
window.open(strUrl, strWindowName[, strWindowFeatures]);
Your code should have:
window.open('Prosjektplan.pdf');
Your code should be:
<p class="downloadBoks"
onclick="window.open('Prosjektplan.pdf')">Prosjektbeskrivelse</p>
You can also use the following code:
<?php
$filename = $_GET["nama"];
$contenttype = "application/force-download";
header("Content-Type: " . $contenttype);
header("Content-Disposition: attachment; filename=\"" . basename($filename) . "\";");
readfile("your file uploaded path".$filename);
exit();
?>
I had a need for an extended version of this: instead of embedding a single number in a string, I needed to generate a series of file names of the form 'file1.pdf', 'file2.pdf' etc. This is how it worked:
['file' + str(i) + '.pdf' for i in range(1,4)]
javascript:document.getElementsByClassName("video-stream html5-main-video")[0].playbackRate = 0.1;
you can put any number here just don't go to far so you don't overun your computer.
Translate composed UInt32 color Value
to CSS in .NET
I know the question applies to 3 input values (red
green
blue
). But there may be the situation where you already have a composed 32bit Value
. It looks like you want to send the data to some HTML CSS renderer (because of the #HEX format). Actually CSS wants you to print 6 or at least 3 zero filled hex digits here. so #{0:X06}
or #{0:X03}
would be required. Due to some strange behaviour, this always prints 8 digits instead of 6.
Solve this by:
String.Format("#{0:X02}{1:X02}{2:X02}", (Value & 0x00FF0000) >> 16, (Value & 0x0000FF00) >> 8, (Value & 0x000000FF) >> 0)
Change this property and try this at design time:
FormBorderStyle = FormBorderStyle.FixedDialog;
Designer view before the change:
If you don't want 'a' in the index
In :
col = ['a','b','c']
data = DataFrame([[1,2,3],[10,11,12],[20,21,22]],columns=col)
data
Out:
a b c
0 1 2 3
1 10 11 12
2 20 21 22
In :
data2 = data.set_index('a')
Out:
b c
a
1 2 3
10 11 12
20 21 22
In :
data2.index.name = None
Out:
b c
1 2 3
10 11 12
20 21 22
Use of Lazy quantifiers ?
with no global flag is the answer.
Eg,
If you had global flag /g
then, it would have matched all the lowest length matches as below.
It is the $sce
service that blocks URLs with external domains, it is a service that provides Strict Contextual Escaping services to AngularJS, to prevent security vulnerabilities such as XSS, clickjacking, etc. it's enabled by default in Angular 1.2.

.NET for Android seems like a real possibility to me. There is news that Microsoft will release proper Silverlight for Android- Never underestimate the advantages to Microsoft for putting the boot into Apple. A smartphone that is faster, more feature rich, faster development lifecycle, impressive hardware, Flash & Silverlight as a standard installable.
Microsoft has a vested interest in improving Android, and at the same time, applications will be devloped for Silverlight on Android will also work on Windows Phone 7 OS with multi-touch, GPS, etc., etc.
You need a different seed at every execution.
You can start to call at the beginning of your program:
srand(time(NULL));
Note that % 10
yields a result from 0
to 9
and not from 1
to 10
: just add 1
to your %
expression to get 1
to 10
.
If you want to transform a variable containing a relative path into an absolute one, this works :
dir=`cd "$dir"`
"cd" echoes without changing the working directory, because executed here in a sub-shell.

Daniel A. White Solution works great for classes.
I've got a situation where I had to find input fields like donee_1_card where 1 is an index.
My solution has been
$("input[name^='donee']" && "input[name*='card']")
Though I am not sure how optimal it is.
You can also do it like this:
BigDecimal A = new BigDecimal("10000000000");
BigDecimal B = new BigDecimal("20000000000");
BigDecimal C = new BigDecimal("30000000000");
BigDecimal resultSum = (A).add(B).add(C);
System.out.println("A+B+C= " + resultSum);
Prints:
A+B+C= 60000000000

I had this problem too and used AMissico's advice too discover the problem (Although had to set verbosity level to Detailed.
The problem was actually quite straight forward though after finding the culprit.
Background: I upgraded my project from VS2008 to VS2010. In VS2008 the target framework was 3.5 and when I brought it into VS2010 I switched it to 4 (Full). I also upgraded some third party components including Crystal reports.
It turned out most of System references where pointing at version 4.0.0.0 but a couple had not been automatically changed (System and System.Web.Services) and were still looking at 2.0.0.0. Crystal reports is referencing 4.0.0.0 and so this was where the conflicts were occuring. Simply putting the cursor at the first System library in the solution explorer, cursor down the list and looking for any references to 2.0.0.0, removing and re-adding newer 4.0.0.0 version did the trick.
The strange this was that most of the references had been correctly updated and if it weren't for Crystal reports, I probably would never had noticed...
At the very core, the file extension you use makes no difference as to how perl
interprets those files.
However, putting modules in .pm
files following a certain directory structure that follows the package name provides a convenience. So, if you have a module Example::Plot::FourD
and you put it in a directory Example/Plot/FourD.pm
in a path in your @INC
, then use
and require
will do the right thing when given the package name as in use Example::Plot::FourD
.
The file must return true as the last statement to indicate successful execution of any initialization code, so it's customary to end such a file with
1;
unless you're sure it'll return true otherwise. But it's better just to put the1;
, in case you add more statements.If
EXPR
is a bareword, therequire
assumes a ".pm" extension and replaces "::" with "/" in the filename for you, to make it easy to load standard modules. This form of loading of modules does not risk altering your namespace.
All use
does is to figure out the filename from the package name provided, require
it in a BEGIN
block and invoke import
on the package. There is nothing preventing you from not using use
but taking those steps manually.
For example, below I put the Example::Plot::FourD
package in a file called t.pl
, loaded it in a script in file s.pl
.
C:\Temp> cat t.pl
package Example::Plot::FourD;
use strict; use warnings;
sub new { bless {} => shift }
sub something { print "something\n" }
"Example::Plot::FourD"
C:\Temp> cat s.pl
#!/usr/bin/perl
use strict; use warnings;
BEGIN {
require 't.pl';
}
my $p = Example::Plot::FourD->new;
$p->something;
C:\Temp> s
something
This example shows that module files do not have to end in 1
, any true value will do.
I used the concept from the answer posted by @marcg and it works great with JPA 2.1. His code wasn't quite right, so I'm posted my working implementation. This will convert Boolean
entity fields to a Y/N character column in the database.
From my entity class:
@Convert(converter=BooleanToYNStringConverter.class)
@Column(name="LOADED", length=1)
private Boolean isLoadedSuccessfully;
My converter class:
/**
* Converts a Boolean entity attribute to a single-character
* Y/N string that will be stored in the database, and vice-versa
*
* @author jtough
*/
public class BooleanToYNStringConverter
implements AttributeConverter<Boolean, String> {
/**
* This implementation will return "Y" if the parameter is Boolean.TRUE,
* otherwise it will return "N" when the parameter is Boolean.FALSE.
* A null input value will yield a null return value.
* @param b Boolean
*/
@Override
public String convertToDatabaseColumn(Boolean b) {
if (b == null) {
return null;
}
if (b.booleanValue()) {
return "Y";
}
return "N";
}
/**
* This implementation will return Boolean.TRUE if the string
* is "Y" or "y", otherwise it will ignore the value and return
* Boolean.FALSE (it does not actually look for "N") for any
* other non-null string. A null input value will yield a null
* return value.
* @param s String
*/
@Override
public Boolean convertToEntityAttribute(String s) {
if (s == null) {
return null;
}
if (s.equals("Y") || s.equals("y")) {
return Boolean.TRUE;
}
return Boolean.FALSE;
}
}
This variant is also fun if you love emoticons and are just sick and tired of Y/N or T/F in your database. In this case, your database column must be two characters instead of one. Probably not a big deal.
/**
* Converts a Boolean entity attribute to a happy face or sad face
* that will be stored in the database, and vice-versa

if (b == null) {

}
if (b) {

@Override
public Boolean convertToEntityAttribute(String s) {
if (s == null) {
return null;
}
if (HAPPY.equals(s)) {
return Boolean.TRUE;
}
return Boolean.FALSE;
}
}
if (iv_new_pwd.isSelected()) {
iv_new_pwd.setSelected(false);

Log.d("mytag", "in case 1");
iv_new_pwd.setSelected(true);
edt_new_pwd.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
}
The EOF pattern needs a prime read to 'bootstrap' the EOF checking process. Consider the empty file will not initially have its EOF set until the first read. The prime read will catch the EOF in this instance and properly skip the loop completely.
What you need to remember here is that you don't get the EOF until the first attempt to read past the available data of the file. Reading the exact amount of data will not flag the EOF.
I should point out if the file was empty your given code would have printed since the EOF will have prevented a value from being set to x on entry into the loop.
So add a prime read and move the loop's read to the end:
int x;
iFile >> x; // prime read here
while (!iFile.eof()) {
cerr << x << endl;
iFile >> x;
}
logical address is address relative to program. It tells how much memory a particular process will take, not tell what will the exact location of the process and this exact location will we generated by using some mapping, and is known as physical address.
Assuming that the OP is invoking a batch file with cmd.exe, to properly break out of a for loop just goto a label;
Change this:
For /L %%f In (1,1,1000000) Do If Not Exist %%f Goto :EOF
To this:
For /L %%f In (1,1,1000000) Do If Not Exist %%f Goto:fileError
.. do something
.. then exit or do somethign else
:fileError
GOTO:EOF
Better still, add some error reporting:
set filename=
For /L %%f In (1,1,1000000) Do(
set filename=%%f
If Not Exist %%f set tempGoto:fileError
)
.. do something
.. then exit or do somethign else
:fileError
echo file does not exist '%filename%'
GOTO:EOF
I find this to be a helpful site about lesser known cmd.exe/DOS batch file functions and tricks: https://www.dostips.com/
If you have Mockito 1.9.5 or higher, there is a new static method that can make the Answer
object for you. You need to write something like
import static org.mockito.Mockito.when;
import static org.mockito.AdditionalAnswers.returnsFirstArg;
when(myMock.myFunction(anyString())).then(returnsFirstArg());
or alternatively
doAnswer(returnsFirstArg()).when(myMock).myFunction(anyString());
Note that the returnsFirstArg()
method is static in the AdditionalAnswers
class, which is new to Mockito 1.9.5; so you'll need the right static import.

On a mac if you install xattr
in python, then your environment may have an issue.
There are two different paths on my mac for
xattr
type -a xattr
# xattr is /usr/local/bin/xattr # PYTHON Installed Version
# xattr is /usr/bin/xattr # Mac OSX Installed Version
So in one of the example's where -c
will not work in xargs is because in bash you default to the non-python version.
-c
/usr/bin/xattr -c
-c
/usr/local/bin/xattr -c
# option -c not recognized
My Shell/Terminal defaults to /usr/local/bin/xattr because my $PATH
/usr/local/bin:
is before /usr/bin:
which I believe is the default.
I can prove this because, if you try to uninstall the python xattr
you will see:
pip3 uninstall xattr
Uninstalling xattr-0.9.6:
Would remove:
/usr/local/bin/xattr
/usr/local/lib/python3.7/site-packages/xattr-0.9.6.dist-info/*
/usr/local/lib/python3.7/site-packages/xattr/*
Proceed (y/n)?
To Fix option -c not recognized
Errors.
xattr
you may have: pip3 uninstall xattr
Terminal
windows & quit Terminal
Terminal
window.xattr
command and it should now work.OR
If you want to keep the Python
xattr
then use
/usr/bin/xattr
for any Shell
commands in Terminal
Python's version of xattr
doesn't handle images at all:

All development is done using your choice of C#, Boo, or a dialect of JavaScript.
Most of the example code in the documentation is in JavaScript; if you poke around the official forums and wiki you'll see a pretty even mix of C# and Javascript. Very few people seem to use Boo, but it's just as good; pick the language you already know or are the happiest learning.
Unity takes your C#/JS/Boo code and compiles it to run on iOS, Android, PC, Mac, XBox, PS3, Wii, or web plugin. Depending on the platform that might end up being Objective C or something else, but that's completely transparent to you. There's really no benefit to knowing Objective C; you can't program in it.
Update 2019/31/01
Starting from Unity 2017.2 "UnityScript" (Unity's version of JavaScript, but not identical to) took its first step towards complete deprecation by removing the option to add a "JavaScript" file from the UI. Though JS files could still be used, support for it will completely be dropped in later versions.
This also means that Boo will become unusable as its compiler is actually built as a layer on top of UnityScript and will thus be removed as well.
This means that in the future only C# will have native support.
unity has released a full article on the deprecation of UnityScript and Boo back in August 2017.
In my case, I already had a period(.)
and also a comma(,)
, so what worked for me was to replace
the comma(,)
with an empty string like below:
parseFloat('3,000.78'.replace(',', ''))
This is assuming that the amount from the existing database is 3,000.78. The results are: 3000.78
without the initial comma(,)
.
Assuming your table of data is called ProjectInfo:
SELECT DISTINCT Contract, Activity
FROM ProjectInfo
WHERE Contract = (SELECT Contract
FROM (SELECT DISTINCT Contract, Activity
FROM ProjectInfo) AS ContractActivities
GROUP BY Contract
HAVING COUNT(*) = 1);
The innermost query identifies the contracts and the activities. The next level of the query (the middle one) identifies the contracts where there is just one activity. The outermost query then pulls the contract and activity from the ProjectInfo table for the contracts that have a single activity.
Tested using IBM Informix Dynamic Server 11.50 - should work elsewhere too.
All these answers do NOT take into account that you asked specifically about a DIV element.
document.querySelector("div#the-div-id")
@see https://developer.mozilla.org/en-US/docs/Web/API/Document/querySelector
Finally, I solved this. (It works till now..)
My solution is like this...
Prepare the layout to show when an error occurred instead of Web Page (a dirty 'page not found message') The layout has one button, "RELOAD" with some guide messages.
If an error occurred, Remember using boolean and show the layout we prepare.

There are a lot excellent answers here, but I want to touch on something I didn't see mentioned: Object oriented design is about empowering objects.
You want to encapsulate all your rules, additional work and internal details inside an appropriate object. In this way other objects interacting with this one don't have to worry about it all. In fact, you want to go a step further and actively prevent other objects from bypassing these internals.
When you inherit from List
, all other objects can see you as a List. They have direct access to the methods for adding and removing players. And you'll have lost your control; for example:
Suppose you want to differentiate when a player leaves by knowing whether they retired, resigned or were fired. You could implement a RemovePlayer
method that takes an appropriate input enum. However, by inheriting from List
, you would be unable to prevent direct access to Remove
, RemoveAll
and even Clear
. As a result, you've actually disempowered your FootballTeam
class.
Additional thoughts on encapsulation... You raised the following concern:
It makes my code needlessly verbose. I must now call my_team.Players.Count instead of just my_team.Count.
You're correct, that would be needlessly verbose for all clients to use you team. However, that problem is very small in comparison to the fact that you've exposed List Players
to all and sundry so they can fiddle with your team without your consent.
You go on to say:
It just plain doesn't make any sense. A football team doesn't "have" a list of players. It is the list of players. You don't say "John McFootballer has joined SomeTeam's players". You say "John has joined SomeTeam".
You're wrong about the first bit: Drop the word 'list', and it's actually obvious that a team does have players.
However, you hit the nail on the head with the second. You don't want clients calling ateam.Players.Add(...)
. You do want them calling ateam.AddPlayer(...)
. And your implemention would (possibly amongst other things) call Players.Add(...)
internally.
Hopefully you can see how important encapsulation is to the objective of empowering your objects. You want to allow each class to do its job well without fear of interference from other objects.
Maybe it is too late, but I am answering for future searches. TO perform spelling mistake correction, you first need to make sure the word is not absurd or from slang like, caaaar, amazzzing etc. with repeated alphabets. So, we first need to get rid of these alphabets. As we know in English language words usually have a maximum of 2 repeated alphabets, e.g., hello., so we remove the extra repetitions from the words first and then check them for spelling. For removing the extra alphabets, you can use Regular Expression module in Python.
Once this is done use Pyspellchecker library from Python for correcting spellings.
For implementation visit this link: https://rustyonrampage.github.io/text-mining/2017/11/28/spelling-correction-with-python-and-nltk.html
You can also get the value by element's name attribute.
var message = $("#formId textarea[name=message]").val();
A char
variable is actually an 8-bit integral value. It will have values from 0
to 255
. These are ASCII codes. 0
stands for the C-null character, and 255
stands for an empty symbol.
So, when you write the following assignment:
char a = 'a';
It is the same thing as:
char a = 97;
So, you can compare two char
variables using the >
, <
, ==
, <=
, >=
operators:
char a = 'a';
char b = 'b';
if( a < b ) printf("%c is smaller than %c", a, b);
if( a > b ) printf("%c is smaller than %c", a, b);
if( a == b ) printf("%c is equal to %c", a, b);
If you put set directory=""
in your exrc file, you will turn off the swap file. However, doing so will disable recovery.

You can add a wrapper around promise functionality to return an Observable to observer.
import { of, Observable, defer } from 'rxjs';
import { map } from 'rxjs/operators';
function getTodos$(): Observable<any> {
return defer(()=>{
return fetch('https://jsonplaceholder.typicode.com/todos/1')
.then(response => response.json())
.then(json => {
return json;
})
});
}
getTodos$().
subscribe(
(next)=>{
console.log('Data is:', next);
}
)
If you are planning to draw a lot of pixel, it's a lot more efficient to use the image data of the canvas to do pixel drawing.
var canvas = document.getElementById("myCanvas");
var canvasWidth = canvas.width;
var canvasHeight = canvas.height;
var ctx = canvas.getContext("2d");
var canvasData = ctx.getImageData(0, 0, canvasWidth, canvasHeight);
// That's how you define the value of a pixel //
function drawPixel (x, y, r, g, b, a) {
var index = (x + y * canvasWidth) * 4;
canvasData.data[index + 0] = r;
canvasData.data[index + 1] = g;
canvasData.data[index + 2] = b;
canvasData.data[index + 3] = a;
}
// That's how you update the canvas, so that your //
// modification are taken in consideration //
function updateCanvas() {
ctx.putImageData(canvasData, 0, 0);
}
Then, you can use it in this way :
drawPixel(1, 1, 255, 0, 0, 255);
drawPixel(1, 2, 255, 0, 0, 255);
drawPixel(1, 3, 255, 0, 0, 255);
updateCanvas();
For more information, you can take a look at this Mozilla blog post : http://hacks.mozilla.org/2009/06/pushing-pixels-with-canvas/

Try using json_encode on the string prior to using json_decode... idk if will work for you but it did for me... I'm using laravel 4 ajaxing through a route param.
$username = "{username: john}";
public function getAjaxSearchName($username)
{
$username = json_encode($username);
die(var_dump(json_decode($username, true)));
}
Just add another way , in normal mode , type ctrl+v
then G

, I don't think it is effective , you should do like @Ed Guiness, head -n 20 > filename in linux.

A "reference" in docker is a pointer to an image. It may be an image name, an image ID, include a registry server in the name, use a sha256 tag to pin the image, and anything else that can be used to point to the image you want to run.
The invalid reference format
error message means docker cannot convert the string you've provided to an image. This may be an invalid name, or it may be from a parsing error earlier in the docker run
command line if that's how you run the image. With a compose file, if you expand a variable in the image name, that variable may not be expanding correctly.
With the docker run
command line, this is often the result in not quoting parameters with spaces, and mistaking the order of the command line. The command line is ordered as:
docker ${args_to_docker} run ${args_to_run} image_ref ${cmd_to_exec}
The most common error in passing args to the run is a volume mapping expanding a path name that includes a space in it, and not quoting the path or escaping the space. E.g.
docker run -v $(pwd):/data image_ref
And the fix is as easy as:
docker run -v "$(pwd):/data" image_ref

Your problem stems from a misunderstanding of the or
operator that is common to people learning programming languages like this. Yes, your immediate problem can be solved by writing x ~= 0 and x ~= 1
, but I'll go into a little more detail about why your attempted solution doesn't work.
When you read x ~=(0 or 1)
or x ~= 0 or 1
it's natural to parse this as you would the sentence "x is not equal to zero or one". In the ordinary understanding of that statement, "x" is the subject, "is not equal to" is the predicate or verb phrase, and "zero or one" is the object, a set of possibilities joined by a conjunction. You apply the subject with the verb to each item in the set.
However, Lua does not parse this based on the rules of English grammar, it parses it in binary comparisons of two elements based on its order of operations. Each operator has a precedence which determines the order in which it will be evaluated. or
has a lower precedence than ~=
, just as addition in mathematics has a lower precedence than multiplication. Everything has a lower precedence than parentheses.
As a result, when evaluating x ~=(0 or 1)
, the interpreter will first compute 0 or 1
(because of the parentheses) and then x ~=
the result of the first computation, and in the second example, it will compute x ~= 0
and then apply the result of that computation to or 1
.
The logical operator or
"returns its first argument if this value is different from nil and false; otherwise, or returns its second argument". The relational operator ~=
is the inverse of the equality operator ==
; it returns true if its arguments are different types (x is a number, right?), and otherwise compares its arguments normally.
Using these rules, x ~=(0 or 1)
will decompose to x ~= 0
(after applying the or
operator) and this will return 'true' if x is anything other than 0, including 1, which is undesirable. The other form, x ~= 0 or 1
will first evaluate x ~= 0
(which may return true or false, depending on the value of x). Then, it will decompose to one of false or 1
or true or 1
. In the first case, the statement will return 1
, and in the second case, the statement will return true
. Because control structures in Lua only consider nil
and false
to be false, and anything else to be true, this will always enter the if
statement, which is not what you want either.
There is no way that you can use binary operators like those provided in programming languages to compare a single variable to a list of values. Instead, you need to compare the variable to each value one by one. There are a few ways to do this. The simplest way is to use De Morgan's laws to express the statement 'not one or zero' (which can't be evaluated with binary operators) as 'not one and not zero', which can trivially be written with binary operators:
if x ~= 1 and x ~= 0 then
print( "X must be equal to 1 or 0" )
return
end
Alternatively, you can use a loop to check these values:
local x_is_ok = false
for i = 0,1 do
if x == i then
x_is_ok = true
end
end
if not x_is_ok then
print( "X must be equal to 1 or 0" )
return
end
Finally, you could use relational operators to check a range and then test that x was an integer in the range (you don't want 0.5, right?)
if not (x >= 0 and x <= 1 and math.floor(x) == x) then
print( "X must be equal to 1 or 0" )
return
end
Note that I wrote x >= 0 and x <= 1
. If you understood the above explanation, you should now be able to explain why I didn't write 0 <= x <= 1
, and what this erroneous expression would return!
Using docker-compose, I found the easiest way to do this is to do a docker ps -a
(after starting my containers with docker-compose up
) and get the ID of the container I want to have an interactive shell in (let's call it xyz123).
Then it's a simple matter to execute
docker exec -ti xyz123 /bin/bash
and voila, an interactive shell.
First, clone the repository using git, e.g. with:
git clone git://github.com/facebook/facebook-ios-sdk.git
That downloads the complete history of the repository, so you can switch to any version. Next, change into the newly cloned repository:
cd facebook-ios-sdk
... and use git checkout <COMMIT>
to change to the right commit:
git checkout 91f25642453
That will give you a warning, since you're no longer on a branch, and have switched directly to a particular version. (This is known as "detached HEAD" state.) Since it sounds as if you only want to use this SDK, rather than actively develop it, this isn't something you need to worry about, unless you're interested in finding out more about how git works.

From Lua.org:
When a function is written enclosed in another function, it has full access to local variables from the enclosing function; this feature is called lexical scoping. Although that may sound obvious, it is not. Lexical scoping, plus first-class functions, is a powerful concept in a programming language, but few languages support that concept.
UPDATE:
If you want to take advantage of Imagick (if it is installed on your server). Note: I didn't use Imagick's nature writeFile
because I was having issues with it on my server. File put contents works just as well.

I have been using this, just execute the function after you store the original image and use that location to create the thumbnail. Edit it to your liking...
function makeThumbnails($updir, $img, $id)
{
$thumbnail_width = 134;
$thumbnail_height = 189;
$thumb_beforeword = "thumb";
$arr_image_details = getimagesize("$updir" . $id . '_' . "$img"); // pass id to thumb name
$original_width = $arr_image_details[0];
$original_height = $arr_image_details[1];
if ($original_width > $original_height) {
$new_width = $thumbnail_width;
$new_height = intval($original_height * $new_width / $original_width);
} else {
$new_height = $thumbnail_height;
$new_width = intval($original_width * $new_height / $original_height);
}
$dest_x = intval(($thumbnail_width - $new_width) / 2);
$dest_y = intval(($thumbnail_height - $new_height) / 2);
if ($arr_image_details[2] == IMAGETYPE_GIF) {
$imgt = "ImageGIF";
$imgcreatefrom = "ImageCreateFromGIF";
}
if ($arr_image_details[2] == IMAGETYPE_JPEG) {
$imgt = "ImageJPEG";
$imgcreatefrom = "ImageCreateFromJPEG";
}
if ($arr_image_details[2] == IMAGETYPE_PNG) {
$imgt = "ImagePNG";
$imgcreatefrom = "ImageCreateFromPNG";
}
if ($imgt) {
$old_image = $imgcreatefrom("$updir" . $id . '_' . "$img");
$new_image = imagecreatetruecolor($thumbnail_width, $thumbnail_height);
imagecopyresized($new_image, $old_image, $dest_x, $dest_y, 0, 0, $new_width, $new_height, $original_width, $original_height);
$imgt($new_image, "$updir" . $id . '_' . "$thumb_beforeword" . "$img");
}
}
The above function creates images with a uniform thumbnail size. If the image doesn't have the same dimensions as the specified thumbnail size (proportionally), it just has blackspace on the top and bottom.
Things to remember:
When custom modules are used (modules other than AppModule) then it is necessary to import the common module in it.
yourmodule.module.ts
import { CommonModule } from '@angular/common';
@NgModule({
imports: [
CommonModule
],
exports:[ ],
declarations: []
})
Use Concat
or Union
extension methods. You have to make sure that you have this direction using System.Linq;
in order to use LINQ extensions methods.
Use the AddRange
method.

My StreamEx library which enhances the Java 8 streams provides a special operation distinct(atLeast)
which can retain only elements appearing at least the specified number of times. So your problem can be solved like this:
List<Integer> repeatingNumbers = StreamEx.of(numbers).distinct(2).toList();
Internally it's similar to @Dave solution, it counts objects, to support other wanted quantities and it's parallel-friendly (it uses ConcurrentHashMap
for parallelized stream, but HashMap
for sequential). For big amounts of data you can get a speed-up using .parallel().distinct(2)
.
In Windows 10, it's still 8191 characters...at least on my machine.
It just cuts off any text after 8191 characters. Well, actually, I got 8196 characters, and after 8196, then it just won't let me type any more.
Here's a script that will test how long of a statement you can use. Well, assuming you have gawk/awk installed.
echo rem this is a test of how long of a line that a .cmd script can generate >testbat.bat
gawk 'BEGIN {printf "echo -----";for (i=10;i^<=100000;i +=10) printf "%%06d----",i;print;print "pause";}' >>testbat.bat
testbat.bat
Pulling with rebase is a good practice in general.
However you cannot do that if your index is not clean, i.e. you have made changes that have not been committed.
You can do this to work around, assuming you want to keep your changes:
git stash
git stash apply stash@{0}
or the simpler git stash pop
I figured I should share my solution, since I wasn't able to find it anywhere, and only figured it out through trial and error.
I indeed was able to transfer ownership of the repository to a team on BitBucket.
Don't add the remote URL that BitBuckets suggests:
git remote add origin https://[email protected]/teamName/repo.git
Instead, add the remote URL without your username:
git remote add origin https://bitbucket.org/teamName/repo.git
This way, when you go to pull from or push to a repo, it prompts you for your username, then for your password: everyone on the team has access to it under their own credentials. This approach only works with teams on BitBucket, even though you can manage user permissions on single-owner repos.

@agstudy's answer didn't work for me with the latest version of ggplot2
, but this did, using maggritr
pipes:
ggplot(data=dat)+
geom_line(aes(Value1, Value2, group=ID, colour=ID),
data = . %>% filter(ID %in% c("P1" , "P3")))
It works because if geom_line
sees that data
is a function, it will call that function with the inherited version of data
and use the output of that function as data
.
just try this code:
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
public class CurrentTimeDateCalendar {
public static void getCurrentTimeUsingDate() {
Date date = new Date();
String strDateFormat = "hh:mm:ss a";
DateFormat dateFormat = new SimpleDateFormat(strDateFormat);
String formattedDate= dateFormat.format(date);
System.out.println("Current time of the day using Date - 12 hour format: " + formattedDate);
}
public static void getCurrentTimeUsingCalendar() {
Calendar cal = Calendar.getInstance();
Date date=cal.getTime();
DateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");
String formattedDate=dateFormat.format(date);
System.out.println("Current time of the day using Calendar - 24 hour format: "+ formattedDate);
}
}
which the sample output is:
Current time of the day using Date - 12 hour format: 11:13:01 PM
Current time of the day using Calendar - 24 hour format: 23:13:01

Since you ask for another way to accomplish your goal, I suggest you use a wrapper class:

Create an anchor:

then link to it:
<a href="http://server/page.html#anchor">Link text</a>
You could try catching the onload event. And stopping the propagation dependent on some flag.
var changeHash = false;
$('ul.questions li a').click(function(event) {
var $this = $(this)
$('.tab').hide(); //you can improve the speed of this selector.
$($this.attr('href')).fadeIn('slow');
StopEvent(event); //notice I've changed this
changeHash = true;
window.location.hash = $this.attr('href');
});
$(window).onload(function(event){
if (changeHash){
changeHash = false;
StopEvent(event);
}
}
function StopEvent(event){
event.preventDefault();
event.stopPropagation();
if ($.browser.msie) {
event.originalEvent.keyCode = 0;
event.originalEvent.cancelBubble = true;
event.originalEvent.returnValue = false;
}
}
Not tested, so can't say if it would work
Take a look at NSXMLParser. It's a SAX-style parser. You should be able to use it to detect tags or other unwanted elements in the XML document and ignore them, capturing only pure text.
try this with jQuery:
$('body').load( url,[data],[callback] );

I second @erickson: The pure data-transfer speed penalty is negligible. Modern CPUs reach a crypto/AES throughput of several hundred MBit/s. So unless you are on resource constrained system (mobile phone) TLS/SSL is fast enough for slinging data around.
But keep in mind that encryption makes caching and load balancing much harder. This might result in a huge performance penalty.
But connection setup is really a show stopper for many application. On low bandwidth, high packet loss, high latency connections (mobile device in the countryside) the additional roundtrips required by TLS might render something slow into something unusable.
For example we had to drop the encryption requirement for access to some of our internal web apps - they where next to unusable if used from china.
The way I handled this was switching the className of a label based on a condition. This way you only need one label and you can have different classes for different states... Hope that helps!
If you wanna hide that column while grid populating, you can do it in aspx page itself like this
<asp:BoundField DataField="test" HeaderText="test" Visible="False" />
slight improvement on @LukeH, there is no need to repeat the "INSERT INTO": and @realPT's answer - no need to have the SELECT:

INSERT INTO @MyList VALUES (1),(2),(3),(4)
SELECT * FROM MyTable
WHERE MyColumn IN (SELECT Value FROM @MyList)

Look into creating Applets if you want to make a website with Java. You most likely wont need to use anything but regular Java, unless you want something more specialized.
If it is a windows system, then it may be because you are using 32 bit winpcap library in a 64 bit pc or vie versa. If it is a 64 bit pc then copy the winpcap library and header packet.lib and wpcap.lib from winpcap/lib/x64 to the winpcap/lib directory and overwrite the existing
To be on the safe side use
os.getenv('FOO') or 'bar'
A corner case with the above answers is when the environment variable is set but is empty
For this special case you get
print(os.getenv('FOO', 'bar'))
# prints new line - though you expected `bar`
or
if "FOO" in os.environ:
print("FOO is here")
# prints FOO is here - however its not
To avoid this just use or
os.getenv('FOO') or 'bar'
Then you get
print(os.getenv('FOO') or 'bar')
# bar
When do we have empty environment variables?
You forgot to set the value in the .env
file
# .env
FOO=
or exported as
$ export FOO=
or forgot to set it in settings.py
# settings.py
os.environ['FOO'] = ''
Update: if in doubt, check out these one-liners
>>> import os; os.environ['FOO'] = ''; print(os.getenv('FOO', 'bar'))
$ FOO= python -c "import os; print(os.getenv('FOO', 'bar'))"
Of course.
That is normal and sane behaviour.
Instead of closing and re-opening, you could rewind
the file.
The following should help
realpath
— Returns canonicalized absolute pathnameis_writable
— Tells whether the filename is writableunlink
— Deletes a fileRun your filepath through realpath, then check if the returned path is writable and if so, unlink it.
Here is a working example in both Javascript and jQuery:
http://jsfiddle.net/GuLYN/312/
//In jQuery
$("#calculate").click(function() {
var num = parseFloat($("#textbox").val());
var new_num = $("#textbox").val(num.toFixed(2));
});
// In javascript
document.getElementById('calculate').onclick = function() {
var num = parseFloat(document.getElementById('textbox').value);
var new_num = num.toFixed(2);
document.getElementById('textbox').value = new_num;
};
?
This works without having to use forms or import any DLLs:
using System.Windows;
using System.Windows.Input;
/// <summary>
/// Gets the current mouse position on screen
/// </summary>
private Point GetMousePosition()
{
// Position of the mouse relative to the window
var position = Mouse.GetPosition(Window);
// Add the window position
return new Point(position.X + Window.Left, position.Y + Window.Top);
}
Use the regular Expression below in to validate a string to make sure it contains numbers, letters, or space only:
[a-zA-Z0-9 ]
http://blogs.mysql.com/peterg/2009/04/
In Mysql 6.1 you will be able to do FORMAT(X,D [,locale_name] )
As in
SELECT format(1234567,2,’de_DE’);
For now this ability does not exist, though you MAY be able to set your locale in your database my.ini check it out.
If the main task is just to use the string in a URL, why not to use slugyfier?
composer require cocur/slugify
then
use Cocur\Slugify\Slugify;
$slugify = new Slugify();
echo $slugify->slugify('Fóø Bår');
It also has many bridges for popular frameworks. E.g. you can use Doctrine Extensions Sluggable behaviour to generate automatically unique slug for each entity in DB and use it in URL.
If you want just to wipe out all accents you can play around with rulesets to satisfy the requirements.
The difference is in the subsystem that each executable targets.
java.exe
targets the CONSOLE
subsystem.javaw.exe
targets the WINDOWS
subsystem.try it like this:
<div id="divContainer">
<div class="divImageHolder">
IMG HERE
</div>
<div class="divImageHolder">
IMG HERE
</div>
<div class="divImageHolder">
IMG HERE
</div>
<br class="clear" />
</div>
<style type="text/css">
#divContainer { margin: 0 auto; width: 800px; }
.divImageHolder { float:left; }
.clear { clear:both; }
</style>
Example 1:
This is how the and operator works.
x and y => if x is false, then x, else y
So in other words, since mylist1
is not False
, the result of the expression is mylist2
. (Only empty lists evaluate to False
.)
Example 2:
The &
operator is for a bitwise and, as you mention. Bitwise operations only work on numbers. The result of a & b is a number composed of 1s in bits that are 1 in both a and b. For example:
>>> 3 & 1
1
It's easier to see what's happening using a binary literal (same numbers as above):
>>> 0b0011 & 0b0001
0b0001
Bitwise operations are similar in concept to boolean (truth) operations, but they work only on bits.
So, given a couple statements about my car
The logical "and" of these two statements is:
(is my car red?) and (does car have wheels?) => logical true of false value
Both of which are true, for my car at least. So the value of the statement as a whole is logically true.
The bitwise "and" of these two statements is a little more nebulous:
(the numeric value of the statement 'my car is red') & (the numeric value of the statement 'my car has wheels') => number
If python knows how to convert the statements to numeric values, then it will do so and compute the bitwise-and of the two values. This may lead you to believe that &
is interchangeable with and
, but as with the above example they are different things. Also, for the objects that can't be converted, you'll just get a TypeError
.
Example 3 and 4:
Numpy implements arithmetic operations for arrays:
Arithmetic and comparison operations on ndarrays are defined as element-wise operations, and generally yield ndarray objects as results.
But does not implement logical operations for arrays, because you can't overload logical operators in python. That's why example three doesn't work, but example four does.
So to answer your and
vs &
question: Use and
.
The bitwise operations are used for examining the structure of a number (which bits are set, which bits aren't set). This kind of information is mostly used in low-level operating system interfaces (unix permission bits, for example). Most python programs won't need to know that.
The logical operations (and
, or
, not
), however, are used all the time.
Even when you asked finally for the opposite, to reform 0s and 1s into Trues and Falses, however, I post an answer about how to transform falses and trues into ones and zeros (1s and 0s), for a whole dataframe, in a single line.
Example given
df <- structure(list(p1_1 = c(TRUE, FALSE, FALSE, NA, TRUE, FALSE,
NA), p1_2 = c(FALSE, TRUE, FALSE, NA, FALSE, NA,
TRUE), p1_3 = c(TRUE,
TRUE, FALSE, NA, NA, FALSE, TRUE), p1_4 = c(FALSE, NA,
FALSE, FALSE, TRUE, FALSE, NA), p1_5 = c(TRUE, NA,
FALSE, TRUE, FALSE, NA, TRUE), p1_6 = c(TRUE, NA,
FALSE, TRUE, FALSE, NA, TRUE), p1_7 = c(TRUE, NA,
FALSE, TRUE, NA, FALSE, TRUE), p1_8 = c(FALSE,
FALSE, NA, FALSE, TRUE, FALSE, NA), p1_9 = c(TRUE,
FALSE, NA, FALSE, FALSE, NA, TRUE), p1_10 = c(TRUE,
FALSE, NA, FALSE, FALSE, NA, TRUE), p1_11 = c(FALSE,
FALSE, NA, FALSE, NA, FALSE, TRUE)), .Names =
c("p1_1", "p1_2", "p1_3", "p1_4", "p1_5", "p1_6",
"p1_7", "p1_8", "p1_9", "p1_10", "p1_11"), row.names =
c(NA, -7L), class = "data.frame")
p1_1 p1_2 p1_3 p1_4 p1_5 p1_6 p1_7 p1_8 p1_9 p1_10 p1_11
1 TRUE FALSE TRUE FALSE TRUE TRUE TRUE FALSE TRUE TRUE FALSE
2 FALSE TRUE TRUE NA NA NA NA FALSE FALSE FALSE FALSE
3 FALSE FALSE FALSE FALSE FALSE FALSE FALSE NA NA NA NA
4 NA NA NA FALSE TRUE TRUE TRUE FALSE FALSE FALSE FALSE
5 TRUE FALSE NA TRUE FALSE FALSE NA TRUE FALSE FALSE NA
6 FALSE NA FALSE FALSE NA NA FALSE FALSE NA NA FALSE
7 NA TRUE TRUE NA TRUE TRUE TRUE NA TRUE TRUE TRUE
Then by running that: df * 1
all Falses and Trues are trasnformed into 1s and 0s. At least, this was happen in the R version that I have (R version 3.4.4 (2018-03-15) ).
> df*1
p1_1 p1_2 p1_3 p1_4 p1_5 p1_6 p1_7 p1_8 p1_9 p1_10 p1_11
1 1 0 1 0 1 1 1 0 1 1 0
2 0 1 1 NA NA NA NA 0 0 0 0
3 0 0 0 0 0 0 0 NA NA NA NA
4 NA NA NA 0 1 1 1 0 0 0 0
5 1 0 NA 1 0 0 NA 1 0 0 NA
6 0 NA 0 0 NA NA 0 0 NA NA 0
7 NA 1 1 NA 1 1 1 NA 1 1 1
I do not know if it a total "safe" command, under all different conditions / dfs.
I'm late to the party, but if you want to do this to an arbitrary element using only CSS, without messing around with positioning, overlay divs etc., you can use an inset box shadow:
box-shadow: inset 0px 0px 0 2000px rgba(0,0,0,0.5);
This will work on any element smaller than 4000 pixels long or wide.

Use the Path
class from System.IO
. It contains useful calls for manipulating file paths, including GetDirectoryName
which does what you want, returning the directory portion of the file path.
Usage is simple.
string directoryPath = Path.GetDirectoryName(filePath);
you can write a function which converts from unsigned long to str, similar to ltostr library function.
char *ultostr(unsigned long value, char *ptr, int base)
{
unsigned long t = 0, res = 0;
unsigned long tmp = value;
int count = 0;
if (NULL == ptr)
{
return NULL;
}
if (tmp == 0)
{
count++;
}
while(tmp > 0)
{
tmp = tmp/base;
count++;
}
ptr += count;
*ptr = '\0';
do
{
res = value - base * (t = value / base);
if (res < 10)
{
* -- ptr = '0' + res;
}
else if ((res >= 10) && (res < 16))
{
* --ptr = 'A' - 10 + res;
}
} while ((value = t) != 0);
return(ptr);
}
you can refer to my blog here which explains implementation and usage with example.
Problem statement – Getting java.awt.HeadlessException while trying to initialize java.awt.Component from the application as the tomcat environment does not have any head(terminal).

To add a new file in SVN
svn add file_name

To add a new file in a directory in SVN
svn add directory_name/file_name
svn commit -m "text about changes"
To add all new files in a directory with some targets (files) are already versioned (added):
svn add directory_name/*
svn commit -m "text about changes"
I wanted the simplest case, finally this is a result:
echo -n 'Tell me the length of this sentence.' | wc -m;

Here is the easiest solution which works for me without writing additional codes.
// To underline text in UILable
NSMutableAttributedString *text = [[NSMutableAttributedString alloc] initWithString:@"Type your text here"];
[text addAttribute:NSUnderlineStyleAttributeName value:@(NSUnderlineStyleSingle) range:NSMakeRange(0, text.length)];

Unknown92 answer helped me (on windows). Note that all versions must fit.
I've downloaded cx_Oracle here, for me the file cx_Oracle-5.2.1-12c.win-amd64-py3.5.exe worked with:
Python and just about every other computer language use the same principles as (I hope) you would use when finding a word in a printed dictionary:
(1) Depending on the human language involved, you have a notion of character ordering: 'a' < 'b' < 'c' etc
(2) First character has more weight than second character: 'az' < 'za' (whether the language is written left-to-right or right-to-left or boustrophedon is quite irrelevant)
(3) If you run out of characters to test, the shorter string is less than the longer string: 'foo' < 'food'
Typically, in a computer language the "notion of character ordering" is rather primitive: each character has a human-language-independent number ord(character)
and characters are compared and sorted using that number. Often that ordering is not appropriate to the human language of the user, and then you need to get into "collating", a fun topic.
Try (short version of Gabi answer idea)
function get_content() {
txt.innerHTML = txt.textContent;
}
function get_content() {_x000D_
txt.innerHTML = txt.textContent ;_x000D_
}
_x000D_
span { background: #fbb}
_x000D_
<input type="button" onclick="get_content()" value="Get Content"/>_x000D_
<p id='txt'>_x000D_
<span class="A">I am</span>_x000D_
<span class="B">working in </span>_x000D_
<span class="C">ABC company.</span>_x000D_
</p>
_x000D_
If a function does not return anything, e.g.:
def test():
pass
it has an implicit return value of None
.
Thus, as your pick*
methods do not return anything, e.g.:
def pickEasy():
word = random.choice(easyWords)
word = str(word)
for i in range(1, len(word) + 1):
wordCount.append("_")
the lines that call them, e.g.:
word = pickEasy()
set word
to None
, so wordInput
in getInput
is None
. This means that:
if guess in wordInput:
is the equivalent of:
if guess in None:
and None
is an instance of NoneType
which does not provide iterator/iteration functionality, so you get that type error.
The fix is to add the return type:
def pickEasy():
word = random.choice(easyWords)
word = str(word)
for i in range(1, len(word) + 1):
wordCount.append("_")
return word
public void capitaliseFirstLetterOfEachWord()
{
String value="this will capitalise first character of each word of this string";
String[] wordSplit=value.split(" ");
StringBuilder sb=new StringBuilder();
for (int i=0;i<wordSplit.length;i++){
sb.append(wordSplit[i].substring(0,1).toUpperCase().
concat(wordSplit[i].substring(1)).concat(" "));
}
System.out.println(sb);
}
Looks like you have a query that is taking longer than it should. From your stack trace and your code you should be able to determine exactly what query that is.
This type of timeout can have three causes;
A deadlock can be difficult to fix, but it's easy to determine whether that is the case. Connect to your database with Sql Server Management Studio. In the left pane right-click on the server node and select Activity Monitor. Take a look at the running processes. Normally most will be idle or running. When the problem occurs you can identify any blocked process by the process state. If you right-click on the process and select details it'll show you the last query executed by the process.
The second issue will cause the database to use a sub-optimal query plan. It can be resolved by clearing the statistics:
exec sp_updatestats
If that doesn't work you could also try
dbcc freeproccache
You should not do this when your server is under heavy load because it will temporarily incur a big performace hit as all stored procs and queries are recompiled when first executed. However, since you state the issue occurs sometimes, and the stack trace indicates your application is starting up, I think you're running a query that is only run on occasionally. You may be better off by forcing SQL Server not to reuse a previous query plan. See this answer for details on how to do that.
I've already touched on the third issue, but you can easily determine whether the query needs tuning by executing the query manually, for example using Sql Server Management Studio. If the query takes too long to complete, even after resetting the statistics you'll probably need to tune it. For help with that, you should post the exact query in a new question.
Just an update.
If the ticked answer is working fine for you but it shows nothing when the search text is empty. Here is the solution:
private class ItemFilter extends Filter {
@Override
protected FilterResults performFiltering(CharSequence constraint) {
String filterString = constraint.toString().toLowerCase();
FilterResults results = new FilterResults();
if(constraint.length() == 0)
{
results.count = originalData.size();
results.values = originalData;
}else {
final List<String> list = originalData;
int count = list.size();
final ArrayList<String> nlist = new ArrayList<String>(count);
String filterableString ;
for (int i = 0; i < count; i++) {
filterableString = list.get(i);
if (filterableString.toLowerCase().contains(filterString)) {
nlist.add(filterableString);
}
}
results.values = nlist;
results.count = nlist.size();
}
return results;
}
@SuppressWarnings("unchecked")
@Override
protected void publishResults(CharSequence constraint, FilterResults results) {
filteredData = (ArrayList<String>) results.values;
notifyDataSetChanged();
}
}

In Nexus version 3.13.0-01, the id
in the POM's distributionManagement/repository
section MUST match the servers/server/id
