What type of authentication do you use? Send the credentials using the properties Ben said before and setup a cookie handler. You already allow redirection, check your webserver if any redirection occurs (NTLM auth does for sure). If there is a redirection you need to store the session which is mostly stored in a session cookie.
For a 10 minute interval, you would
GROUP BY (DATEPART(MINUTE, [Date]) / 10)
As was already mentioned by tzup and Pieter888... to do an hour interval, just
GROUP BY DATEPART(HOUR, [Date])
You need to leverage the @ViewChild
decorator to reference the child component from the parent one by injection:
import { Component, ViewChild } from 'angular2/core';
(...)
@Component({
selector: 'my-app',
template: `
<h1>My First Angular 2 App</h1>
<child></child>
<button (click)="submit()">Submit</button>
`,
directives:[App]
})
export class AppComponent {
@ViewChild(Child) child:Child;
(...)
someOtherMethod() {
this.searchBar.someMethod();
}
}
Here is the updated plunkr: http://plnkr.co/edit/mrVK2j3hJQ04n8vlXLXt?p=preview.
You can notice that the @Query
parameter decorator could also be used:
export class AppComponent {
constructor(@Query(Child) children:QueryList<Child>) {
this.childcmp = children.first();
}
(...)
}
UPDATE: for your updated question
variable.match(/\[[0-9]+\]/);
Try this:
variable.match(/[0-9]+/); // for unsigned integers
variable.match(/[-0-9]+/); // for signed integers
variable.match(/[-.0-9]+/); // for signed float numbers
Hope this helps!
Method for converting from one timeZone to other(probably it works :) ).
/**
* Adapt calendar to client time zone.
* @param calendar - adapting calendar
* @param timeZone - client time zone
* @return adapt calendar to client time zone
*/
public static Calendar convertCalendar(final Calendar calendar, final TimeZone timeZone) {
Calendar ret = new GregorianCalendar(timeZone);
ret.setTimeInMillis(calendar.getTimeInMillis() +
timeZone.getOffset(calendar.getTimeInMillis()) -
TimeZone.getDefault().getOffset(calendar.getTimeInMillis()));
ret.getTime();
return ret;
}
I was going through some details related to tuple
and list
, and what I understood is:
Heterogeneous
collection data typeSo for appending new item to a tuple, need to cast it to list
, and do append()
operation on it, then again cast it back to tuple.
But personally what I felt about the Question is, if Tuples are supposed to be finite, fixed length items and if we are using those data types in our application logics then there should not be a scenario to appending new items OR updating an item value in it. So instead of list of tuples it should be list of list itself, Am I right on this?
$timeIn30Minutes = mktime(idate("H"), idate("i") + 30);
or
$timeIn30Minutes = time() + 30*60; // 30 minutes * 60 seconds/minute
The result will be a UNIX timestamp of the current time plus 30 minutes.
For Windows users, Ruby doesn't set up .gemrc file. So you have to create .gemrc file in your home directory (echo %USERPROFILE%
) and put following line in it:
gem: --no-document
As already mentioned in previous answers, don't use --no-ri and --no-rdoc cause its deprecated. See it yourself:
gem help install
Maybe this table helps.
Calling the callme()
method of class Parent
or class Child
.
As a principle:
UPCASTING --> Hiding
DOWNCASTING --> Revealing
For this example we take it for granted that varcharcol doesn't contain ''
and have no empty cell against this column
select * from some_table where varcharCol = ''
select * from some_table where varcharCol like ''
The first one results in 0 row output while the second one shows the whole list. = is strictly-match case while like acts like a filter. if filter has no criteria, every data is valid.
like - by the virtue of its purpose works a little slower and is intended for use with varchar and similar data.
You can use some code like this, you can adjust a height and width as per your need
protected void button_Click(object sender, EventArgs e)
{
// open a pop up window at the center of the page.
ScriptManager.RegisterStartupScript(this, typeof(string), "OPEN_WINDOW", "var Mleft = (screen.width/2)-(760/2);var Mtop = (screen.height/2)-(700/2);window.open( 'your_page.aspx', null, 'height=700,width=760,status=yes,toolbar=no,scrollbars=yes,menubar=no,location=no,top=\'+Mtop+\', left=\'+Mleft+\'' );", true);
}
this is just a shot in the dark : when you call connect without a bind first, the system allocates your local port, and if you have multiple threads connecting and disconnecting it could possibly try to allocate a port already in use. the kernel source file inet_connection_sock.c hints at this condition. just as an experiment try doing a bind to a local port first, making sure each bind/connect uses a different local port number.
SELECT * FROM table WHERE arr && '{s}'::text[];
Compare two arrays for containment.
In gcc, this isn't supported. In fact, this isn't supported in any existing compiler/linker i'm aware of.
svn move

Here's a general solution that will handle an arbitrary amount of dictionaries, with cases when keys are in only some of the dictionaries:
from collections import defaultdict
d1 = {1: 2, 3: 4}
d2 = {1: 6, 3: 7}
dd = defaultdict(list)
for d in (d1, d2): # you can list as many input dicts as you want here
for key, value in d.items():
dd[key].append(value)
print(dd)
Shows:
defaultdict(<type 'list'>, {1: [2, 6], 3: [4, 7]})
Also, to get your .attrib
, just change append(value)
to append(value.attrib)
I had this issue... It was the log that was huge. Logs are here :
/var/lib/docker/containers/<container id>/<container id>-json.log
You can manage this in the run command line or in the compose file. See there : Configure logging drivers
I personally added these 3 lines to my docker-compose.yml file :
my_container:
logging:
options:
max-size: 10m
Call the function in this way:
self.parse_file()
You also need to define your parse_file() function like this:
def parse_file(self):
The parse_file
method has to be bound to an object upon calling it (because it's not a static method). This is done by calling the function on an instance of the object, in your case the instance is self
.
wget -O yourfilename.zip remote-storage.url/theirfilename.zip
will do the trick for you.
Note:
a) its a capital O.
b) wget -O filename url
will only work. Putting -O
last will not.
Am using windows 8 n this issue got resolved by changing the environment variables
follow these steps: Open my computer properties->advanced system settings->Environment variables. Under 'system variables', select 'path' and click on 'edit' In 'variable value', add 'C:\php;' OR the path where php installed.
click OK and apply the settings and restart the system. It should work.
I was brought here for a reason not explicitly mentioned in the answers so far, so to save others the trouble:
The error also occurs if the function arguments have changed order - for the same reason as in the accepted answer: the positional arguments clash with the keyword arguments.
In my case it was because the argument order of the Pandas set_axis
function changed between 0.20 and 0.22:
0.20: DataFrame.set_axis(axis, labels)
0.22: DataFrame.set_axis(labels, axis=0, inplace=None)
Using the commonly found examples for set_axis results in this confusing error, since when you call:
df.set_axis(['a', 'b', 'c'], axis=1)
prior to 0.22, ['a', 'b', 'c']
is assigned to axis because it's the first argument, and then the positional argument provides "multiple values".
To round an integer to 1 significant figure the basic idea is to convert it to a floating point with 1 digit before the point and round that, then convert it back to its original integer size.
To do this we need to know the largest power of 10 less than the integer. We can use floor of the log 10 function for this.
from math import log10, floor def round_int(i,places): if i == 0: return 0 isign = i/abs(i) i = abs(i) if i < 1: return 0 max10exp = floor(log10(i)) if max10exp+1 < places: return i sig10pow = 10**(max10exp-places+1) floated = i*1.0/sig10pow defloated = round(floated)*sig10pow return int(defloated*isign)
I use icons next to text 99% of the time so I made the change globally:
.fa-2x {
vertical-align: middle;
}
Add 3x, 4x, etc to the same definition as needed.

I needed a way to do this in an AJAX return, so I wrote this piece:

<div id="results"></div>
<script type="text/javascript">
$(function(){
ajax();
})
//Function that makes Ajax call out to receive search results
var ajax = function() {
//Setup Ajax
$.ajax({
url: '/path/to/url', //URL to load
type: 'GET', //Type of Ajax call
dataType: 'html', //Type of data to be expected on return
success: function(data) { //Function that manipulates the returned AJAX'ed data
$('#results').html(data); //Load the data into a HTML holder
var $el = $('#results'); //jQuery Object that is holding the results
setTimeout(function(){ //Custom callback function to count the number of results
callBack($el);
});
}
});
}
//Custom Callback function to return the number of results
var callBack = function(el) {
var length = $('tr', $(el)).not('tr:first').length; //Count all TR DOM elements, except the first row (which contains the header information)
$('#num_results span').text(length); //Write the counted results to the DOM
}
</script>
Obviously this is a quick example, but it may be helpful.
You mention you are using OS X- I have used cronnix in the past. It's not as geeky as editing it yourself, but it helped me learn what the columns are in a jiffy. Just a thought.
Try this:
@Html.ActionLink("DisplayText", "Action", "Controller", route, attribute)
in your code should be,
@Html.ActionLink("Search", "List", "Search", new{@class="btn btn-info", @id="addressSearch"})
When merging topic branch "B" in "A" using git merge, I get some conflicts. I >know all the conflicts can be solved using the version in "B".
I am aware of git merge -s ours. But what I want is something like git merge >-s their.
I'm assuming that you created a branch off of master and now want to merge back into master, overriding any of the old stuff in master. That's exactly what I wanted to do when I came across this post.
Do exactly what it is you want to do, Except merge the one branch into the other first. I just did this, and it worked great.
git checkout Branch
git merge master -s ours
Then, checkout master and merge your branch in it (it will go smoothly now):
git checkout master
git merge Branch
I personally think that sizeof(a) / sizeof(*a) looks cleaner.
I also prefer to define it as a macro:
#define NUM(a) (sizeof(a) / sizeof(*a))
Then you can use it in for-loops, thusly:
for (i = 0; i < NUM(a); i++)
Replace all require
statements with import
statements. Example:
// Before:
const Web3 = require('web3');
// After:
import Web3 from 'web3';
It worked for me.
I did the following to add a role 'eSumit' on PostgreSQL 9.4.15 database and provide all permission to this role :
CREATE ROLE eSumit;
GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO eSumit;
GRANT ALL PRIVILEGES ON DATABASE "postgres" to eSumit;
ALTER USER eSumit WITH SUPERUSER;
Also checked the pg_table enteries via :
If you want True False
use:
"%s %s" % (True, False)
because str(True)
is 'True'
and str(False)
is 'False'
.
or if you want 1 0
use:
"%i %i" % (True, False)
because int(True)
is 1
and int(False)
is 0
.
And to complement Rich's recursive answer, a non-recursive method.
Public Sub NonRecursiveMethod()
Dim fso, oFolder, oSubfolder, oFile, queue As Collection
Set fso = CreateObject("Scripting.FileSystemObject")
Set queue = New Collection
queue.Add fso.GetFolder("your folder path variable") 'obviously replace
Do While queue.Count > 0
Set oFolder = queue(1)
queue.Remove 1 'dequeue
'...insert any folder processing code here...
For Each oSubfolder In oFolder.SubFolders
queue.Add oSubfolder 'enqueue
Next oSubfolder
For Each oFile In oFolder.Files
'...insert any file processing code here...
Next oFile
Loop
End Sub
You can use a queue for FIFO behaviour (shown above), or you can use a stack for LIFO behaviour which would process in the same order as a recursive approach (replace Set oFolder = queue(1)
with Set oFolder = queue(queue.Count)
and replace queue.Remove(1)
with queue.Remove(queue.Count)
, and probably rename the variable...)
I'm writing an updated answer for Python 3 to this question.
How is
__eq__
handled in Python and in what order?a == b
It is generally understood, but not always the case, that a == b
invokes a.__eq__(b)
, or type(a).__eq__(a, b)
.
Explicitly, the order of evaluation is:
b
's type is a strict subclass (not the same type) of a
's type and has an __eq__
, call it and return the value if the comparison is implemented,a
has __eq__
, call it and return it if the comparison is implemented,__eq__
and it has it, then call and return it if the comparison is implemented,is
.We know if a comparison isn't implemented if the method returns NotImplemented
.
(In Python 2, there was a __cmp__
method that was looked for, but it was deprecated and removed in Python 3.)
Let's test the first check's behavior for ourselves by letting B subclass A, which shows that the accepted answer is wrong on this count:
class A:
value = 3
def __eq__(self, other):
print('A __eq__ called')
return self.value == other.value
class B(A):
value = 4
def __eq__(self, other):
print('B __eq__ called')
return self.value == other.value
a, b = A(), B()
a == b
which only prints B __eq__ called
before returning False
.
The other answers here seem incomplete and out of date, so I'm going to update the information and show you how how you could look this up for yourself.
This is handled at the C level.
We need to look at two different bits of code here - the default __eq__
for objects of class object
, and the code that looks up and calls the __eq__
method regardless of whether it uses the default __eq__
or a custom one.
__eq__
Looking __eq__
up in the relevant C api docs shows us that __eq__
is handled by tp_richcompare
- which in the "object"
type definition in cpython/Objects/typeobject.c
is defined in object_richcompare
for case Py_EQ:
.
case Py_EQ:
/* Return NotImplemented instead of False, so if two
objects are compared, both get a chance at the
comparison. See issue #1393. */
res = (self == other) ? Py_True : Py_NotImplemented;
Py_INCREF(res);
break;
So here, if self == other
we return True
, else we return the NotImplemented
object. This is the default behavior for any subclass of object that does not implement its own __eq__
method.
__eq__
gets calledThen we find the C API docs, the PyObject_RichCompare function, which calls do_richcompare
.
Then we see that the tp_richcompare
function, created for the "object"
C definition is called by do_richcompare
, so let's look at that a little more closely.
The first check in this function is for the conditions the objects being compared:
__eq__
method,then call the other's method with the arguments swapped, returning the value if implemented. If that method isn't implemented, we continue...
if (!Py_IS_TYPE(v, Py_TYPE(w)) &&
PyType_IsSubtype(Py_TYPE(w), Py_TYPE(v)) &&
(f = Py_TYPE(w)->tp_richcompare) != NULL) {
checked_reverse_op = 1;
res = (*f)(w, v, _Py_SwappedOp[op]);
if (res != Py_NotImplemented)
return res;
Py_DECREF(res);
Next we see if we can lookup the __eq__
method from the first type and call it.
As long as the result is not NotImplemented, that is, it is implemented, we return it.
if ((f = Py_TYPE(v)->tp_richcompare) != NULL) {
res = (*f)(v, w, op);
if (res != Py_NotImplemented)
return res;
Py_DECREF(res);
Else if we didn't try the other type's method and it's there, we then try it, and if the comparison is implemented, we return it.
if (!checked_reverse_op && (f = Py_TYPE(w)->tp_richcompare) != NULL) {
res = (*f)(w, v, _Py_SwappedOp[op]);
if (res != Py_NotImplemented)
return res;
Py_DECREF(res);
}
Finally, we get a fallback in case it isn't implemented for either one's type.
The fallback checks for the identity of the object, that is, whether it is the same object at the same place in memory - this is the same check as for self is other
:
/* If neither object implements it, provide a sensible default
for == and !=, but raise an exception for ordering. */
switch (op) {
case Py_EQ:
res = (v == w) ? Py_True : Py_False;
break;
In a comparison, we respect the subclass implementation of comparison first.
Then we attempt the comparison with the first object's implementation, then with the second's if it wasn't called.
Finally we use a test for identity for comparison for equality.
The type of the elements of an std::map
(which is also the type of an expression obtained by dereferencing an iterator of that map) whose key is K
and value is V
is std::pair<const K, V>
- the key is const
to prevent you from interfering with the internal sorting of map values.
std::pair<>
has two members named first
and second
(see here), with quite an intuitive meaning. Thus, given an iterator i
to a certain map, the expression:
i->first
Which is equivalent to:
(*i).first
Refers to the first (const
) element of the pair
object pointed to by the iterator - i.e. it refers to a key in the map. Instead, the expression:
i->second
Which is equivalent to:
(*i).second
Refers to the second element of the pair
- i.e. to the corresponding value in the map.
./
refers to the current working directory, except in the require()
function. When using require()
, it translates ./
to the directory of the current file called. __dirname
is always the directory of the current file.
For example, with the following file structure
/home/user/dir/files/config.json
{
"hello": "world"
}
/home/user/dir/files/somefile.txt
text file
/home/user/dir/dir.js
var fs = require('fs');
console.log(require('./files/config.json'));
console.log(fs.readFileSync('./files/somefile.txt', 'utf8'));
If I cd
into /home/user/dir
and run node dir.js
I will get
{ hello: 'world' }
text file
But when I run the same script from /home/user/
I get
{ hello: 'world' }
Error: ENOENT, no such file or directory './files/somefile.txt'
at Object.openSync (fs.js:228:18)
at Object.readFileSync (fs.js:119:15)
at Object.<anonymous> (/home/user/dir/dir.js:4:16)
at Module._compile (module.js:432:26)
at Object..js (module.js:450:10)
at Module.load (module.js:351:31)
at Function._load (module.js:310:12)
at Array.0 (module.js:470:10)
at EventEmitter._tickCallback (node.js:192:40)
Using ./
worked with require
but not for fs.readFileSync
. That's because for fs.readFileSync
, ./
translates into the cwd (in this case /home/user/
). And /home/user/files/somefile.txt
does not exist.
set statusline=%<%f%m\ \[%{&ff}:%{&fenc}:%Y]\ %{getcwd()}\ \ \[%{strftime('%Y/%b/%d\ %a\ %I:%M\ %p')}\]\ %=\ Line:%l\/%L\ Column:%c%V\ %P
This is mine, give as a suggestion
I do a lot of logging where the timestamps are float64 and use this function to get the timestamps as string:
func dateFormat(layout string, d float64) string{
intTime := int64(d)
t := time.Unix(intTime, 0)
if layout == "" {
layout = "2006-01-02 15:04:05"
}
return t.Format(layout)
}
As others have pointed out, paste()
is the way to go. But it can get annoying to have to type paste(str1, str2, str3, sep='')
everytime you want the non-default separator.
You can very easily create wrapper functions that make life much simpler. For instance, if you find yourself concatenating strings with no separator really often, you can do:
p <- function(..., sep='') {
paste(..., sep=sep, collapse=sep)
}
or if you often want to join strings from a vector (like implode()
from PHP):
implode <- function(..., sep='') {
paste(..., collapse=sep)
}
Allows you do do this:
p('a', 'b', 'c')
#[1] "abc"
vec <- c('a', 'b', 'c')
implode(vec)
#[1] "abc"
implode(vec, sep=', ')
#[1] "a, b, c"
Also, there is the built-in paste0
, which does the same thing as my implode
, but without allowing custom separators. It's slightly more efficient than paste()
.
For a list X = ['a', 'b', 'c', 'd', 'e', 'f']
and a desired shift value of shift
less than list length, we can define the function list_shift()
as below
def list_shift(my_list, shift):
assert shift < len(my_list)
return my_list[shift:] + my_list[:shift]
Examples,
list_shift(X,1)
returns ['b', 'c', 'd', 'e', 'f', 'a']
list_shift(X,3)
returns ['d', 'e', 'f', 'a', 'b', 'c']
Yes! You can use Range.EntireColumn
MSDN
dim column : column = 4
dim column_range : set column_range = Sheets(1).Cells(column).EntireColumn
If you were after a specific column, you could create a hard coded column range with the syntax e.g. Range("D:D")
.
However, I'd use entire column as it provides more flexibility to change that column at a later time.
Worksheet.Columns
provides Range access to a column within a worksheet. MSDN
If you would like access to the first column of the first sheet. You would
call the Columns
function on the worksheet.
dim column_range: set column_range = Sheets(1).Columns(1)
The Columns
property is also available on any Range

EntireRow
can also be useful if you have a range for a single cell but would like to reach other cells on the row, akin to a LOOKUP
dim id : id = 12345
dim found : set found = Range("A:A").Find(id)
if not found is Nothing then
'Get the fourth cell from the match
MsgBox found.EntireRow.Cells(4)
end if
Just to enhance @adivis12 answer, you don't need to do the if
statement. Put it like this:
fig, ax = plt.subplots()
for BAR in dict_of_dfs.keys():
dict_of_dfs[BAR].plot(ax=ax)
From RFC 2616, section 4.3, "Message Body":
A server SHOULD read and forward a message-body on any request; if the request method does not include defined semantics for an entity-body, then the message-body SHOULD be ignored when handling the request.
That is, servers should always read any provided request body from the network (check Content-Length or read a chunked body, etc). Also, proxies should forward any such request body they receive. Then, if the RFC defines semantics for the body for the given method, the server can actually use the request body in generating a response. However, if the RFC does not define semantics for the body, then the server should ignore it.
This is in line with the quote from Fielding above.
Section 9.3, "GET", describes the semantics of the GET method, and doesn't mention request bodies. Therefore, a server should ignore any request body it receives on a GET request.
A variation on the .agg() function; provides the ability to (1) persist type DataFrame, (2) apply averages, counts, summations, etc. and (3) enables groupby on multiple columns while maintaining legibility.
df.groupby(['att1', 'att2']).agg({'att1': "count", 'att3': "sum",'att4': 'mean'})
using your values...
df.groupby(['Name', 'Fruit']).agg({'Number': "sum"})
You could do a Select Into, which would create the table structure on the fly based on the fields you select, but I don't think it will create an identity field for you.
The ApplicationPoolIdentity
is assigned membership of the Users
group as well as the IIS_IUSRS
group. On first glance this may look somewhat worrying, however the Users
group has somewhat limited NTFS rights.
For example, if you try and create a folder in the C:\Windows
folder then you'll find that you can't. The ApplicationPoolIdentity
still needs to be able to read files from the windows system folders (otherwise how else would the worker process be able to dynamically load essential DLL's).
With regard to your observations about being able to write to your c:\dump
folder. If you take a look at the permissions in the Advanced Security Settings, you'll see the following:
See that Special permission being inherited from c:\
:
That's the reason your site's ApplicationPoolIdentity
can read and write to that folder. That right is being inherited from the c:\
drive.
In a shared environment where you possibly have several hundred sites, each with their own application pool and Application Pool Identity, you would store the site folders in a folder or volume that has had the Users
group removed and the permissions set such that only Administrators and the SYSTEM account have access (with inheritance).
You would then individually assign the requisite permissions each IIS AppPool\[name]
requires on it's site root folder.
You should also ensure that any folders you create where you store potentially sensitive files or data have the Users
group removed. You should also make sure that any applications that you install don't store sensitive data in their c:\program files\[app name]
folders and that they use the user profile folders instead.
So yes, on first glance it looks like the ApplicationPoolIdentity
has more rights than it should, but it actually has no more rights than it's group membership dictates.
An ApplicationPoolIdentity
's group membership can be examined using the SysInternals Process Explorer tool. Find the worker process that is running with the Application Pool Identity you're interested in (you will have to add the User Name
column to the list of columns to display:
For example, I have a pool here named 900300
which has an Application Pool Identity of IIS APPPOOL\900300
. Right clicking on properties for the process and selecting the Security tab we see:
As we can see IIS APPPOOL\900300
is a member of the Users
group.
Compare integer and print its value in value ascending or descending order. All you have to do is implements Comparator interface and override its compare method and compare its value as below:
@Override
public int compare(Integer o1, Integer o2) {
if (ascending) {
return o1.intValue() - o2.intValue();
} else {
return o2.intValue() - o1.intValue();
}
}
I had the similar issue, 0.0% coverage & no unit tests count on Sonar dashboard with SonarQube 6.7.2: Maven : 3.5.2, Java : 1.8, Jacoco : Worked with 7.0/7.9/8.0, OS : Windows
After a lot of struggle finding for correct solution on maven multi-module project,not like single module project here we need to say to pick jacoco reports from individual modules & merge to one report,So resolved issue with this configuration as my parent pom looks like:

I've tried few other options like jacoco-aggregate & even creating a sub-module by including that in parent pom but nothing really worked & this is simple. I see in logs <sonar.jacoco.reportPath>
is deprecated,but still works as is and seems like auto replaced on execution or can be manually updated to <sonar.jacoco.reportPaths>
or latest. Once after doing setup in cmd start with mvn clean install then mvn org.jacoco:jacoco-maven-plugin:prepare-agent install (Check on project's target folder whether jacoco.exec is created) & then do mvn sonar:sonar , this is what I've tried please let me know if some other best possible solution available.Hope this helps!! If not please post your question..
The question was: "Is it possible to make a HTML5 slider with two input values, for example to select a price range? If so, how can it be done?"
Ten years ago the answer was probably 'No'. However, times have changed. In 2020 it is finally possible to create a fully accessible, native, non-jquery HTML5 slider with two thumbs for price ranges. If found this posted after I already created this solution and I thought that it would be nice to share my implementation here.
This implementation has been tested on mobile Chrome and Firefox (Android) and Chrome and Firefox (Linux). I am not sure about other platforms, but it should be quite good. I would love to get your feedback and improve this solution.
This solution allows multiple instances on one page and it consists of just two inputs (each) with descriptive labels for screen readers. You can set the thumb size in the amount of grid labels. Also, you can use touch, keyboard and mouse to interact with the slider. The value is updated during adjustment, due to the 'on input' event listener.
My first approach was to overlay the sliders and clip them. However, that resulted in complex code with a lot of browser dependencies. Then I recreated the solution with two sliders that were 'inline'. This is the solution you will find below.
var thumbsize = 14;
function draw(slider,splitvalue) {
/* set function vars */
var min = slider.querySelector('.min');
var max = slider.querySelector('.max');
var lower = slider.querySelector('.lower');
var upper = slider.querySelector('.upper');
var legend = slider.querySelector('.legend');
var thumbsize = parseInt(slider.getAttribute('data-thumbsize'));
var rangewidth = parseInt(slider.getAttribute('data-rangewidth'));
var rangemin = parseInt(slider.getAttribute('data-rangemin'));
var rangemax = parseInt(slider.getAttribute('data-rangemax'));
/* set min and max attributes */
min.setAttribute('max',splitvalue);
max.setAttribute('min',splitvalue);
/* set css */
min.style.width = parseInt(thumbsize + ((splitvalue - rangemin)/(rangemax - rangemin))*(rangewidth - (2*thumbsize)))+'px';
max.style.width = parseInt(thumbsize + ((rangemax - splitvalue)/(rangemax - rangemin))*(rangewidth - (2*thumbsize)))+'px';
min.style.left = '0px';
max.style.left = parseInt(min.style.width)+'px';
min.style.top = lower.offsetHeight+'px';
max.style.top = lower.offsetHeight+'px';
legend.style.marginTop = min.offsetHeight+'px';
slider.style.height = (lower.offsetHeight + min.offsetHeight + legend.offsetHeight)+'px';
/* correct for 1 off at the end */
if(max.value>(rangemax - 1)) max.setAttribute('data-value',rangemax);
/* write value and labels */
max.value = max.getAttribute('data-value');
min.value = min.getAttribute('data-value');
lower.innerHTML = min.getAttribute('data-value');
upper.innerHTML = max.getAttribute('data-value');
}
function init(slider) {
/* set function vars */
var min = slider.querySelector('.min');
var max = slider.querySelector('.max');
var rangemin = parseInt(min.getAttribute('min'));
var rangemax = parseInt(max.getAttribute('max'));
var avgvalue = (rangemin + rangemax)/2;
var legendnum = slider.getAttribute('data-legendnum');
/* set data-values */
min.setAttribute('data-value',rangemin);
max.setAttribute('data-value',rangemax);
/* set data vars */
slider.setAttribute('data-rangemin',rangemin);
slider.setAttribute('data-rangemax',rangemax);
slider.setAttribute('data-thumbsize',thumbsize);
slider.setAttribute('data-rangewidth',slider.offsetWidth);
/* write labels */
var lower = document.createElement('span');
var upper = document.createElement('span');
lower.classList.add('lower','value');
upper.classList.add('upper','value');
lower.appendChild(document.createTextNode(rangemin));
upper.appendChild(document.createTextNode(rangemax));
slider.insertBefore(lower,min.previousElementSibling);
slider.insertBefore(upper,min.previousElementSibling);
/* write legend */
var legend = document.createElement('div');
legend.classList.add('legend');
var legendvalues = [];
for (var i = 0; i < legendnum; i++) {
legendvalues[i] = document.createElement('div');
var val = Math.round(rangemin+(i/(legendnum-1))*(rangemax - rangemin));
legendvalues[i].appendChild(document.createTextNode(val));
legend.appendChild(legendvalues[i]);
}
slider.appendChild(legend);
/* draw */
draw(slider,avgvalue);
/* events */
min.addEventListener("input", function() {update(min);});
max.addEventListener("input", function() {update(max);});
}
function update(el){
/* set function vars */
var slider = el.parentElement;
var min = slider.querySelector('#min');
var max = slider.querySelector('#max');
var minvalue = Math.floor(min.value);
var maxvalue = Math.floor(max.value);
/* set inactive values before draw */
min.setAttribute('data-value',minvalue);
max.setAttribute('data-value',maxvalue);
var avgvalue = (minvalue + maxvalue)/2;
/* draw */
draw(slider,avgvalue);
}
var sliders = document.querySelectorAll('.min-max-slider');
sliders.forEach( function(slider) {
init(slider);
});

cardeal's answer was really helpful. Took it a little further and figured it may help others some where down the line. Here is the fiddle:
https://jsfiddle.net/vtL5x0wh/
And the code:

$scope.checkboxModel = {

Check out if you are missing some import.
You were on the right track with response.getOutputStream()
, but you're not using its output anywhere in your code. Essentially what you need to do is to stream the PDF file's bytes directly to the output stream and flush the response. In Spring you can do it like this:
@RequestMapping(value="/getpdf", method=RequestMethod.POST)
public ResponseEntity<byte[]> getPDF(@RequestBody String json) {
// convert JSON to Employee
Employee emp = convertSomehow(json);
// generate the file
PdfUtil.showHelp(emp);
// retrieve contents of "C:/tmp/report.pdf" that were written in showHelp
byte[] contents = (...);
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_PDF);
// Here you have to set the actual filename of your pdf
String filename = "output.pdf";
headers.setContentDispositionFormData(filename, filename);
headers.setCacheControl("must-revalidate, post-check=0, pre-check=0");
ResponseEntity<byte[]> response = new ResponseEntity<>(contents, headers, HttpStatus.OK);
return response;
}
Notes:
showHelp
is not a good ideabyte[]
: example hereshowHelp()
to avoid overwriting the file if two users send a request at the same timeWhat about LineSentence module, it will ignore such lines:
Bases: object
Simple format: one sentence = one line; words already preprocessed and separated by whitespace.
source can be either a string or a file object. Clip the file to the first limit lines (or not clipped if limit is None, the default).
from gensim.models.word2vec import LineSentence
text = LineSentence('text.txt')
document.getElementById("elementID").scrollIntoView();
Same thing, but wrapping it in a function:
function scrollIntoView(eleID) {
var e = document.getElementById(eleID);
if (!!e && e.scrollIntoView) {
e.scrollIntoView();
}
}
This even works in an IFrame on an iPhone.

First off all I would like to thanks @MaximShoustin.
Thanks of you I have really nice table.
I provide some small modification in $scope.range
and $scope.setPage
.
In this way I have now possibility to go to the last page or come back to the first page.
Also when I'm going to next or prev page the navigation is changing when $scope.gap
is crossing. And the current page is not always on first position. For me it's looking more nicer.
Here is the new fiddle example: http://jsfiddle.net/qLBRZ/3/
I'm not sure if my answer is direct answer to original question, but as I suppose a lot of people come here to just find a way to tell their IDEs to understand types, I'll share what I found.
If you want to tell VSCode to understand your types, do as follows. Please pay attention that js
runtime and NodeJS
does not care about these types at all.
1- Create a file with .d.ts
ending: e.g: index.d.ts
. You can create this file in another folder. for example: types/index.d.ts
2- Suppose we want to have a function called view
. Add these lines to index.d.ts
:
/**
* Use express res.render function to render view file inside layout file.
*
* @param {string} view The path of the view file, relative to view root dir.
* @param {object} options The options to send to view file for ejs to use when rendering.
* @returns {Express.Response.render} .
*/
view(view: string, options?: object): Express.Response.render;
3- Create a jsconfig.json
file in you project's root. (It seems that just creating this file is enough for VSCode to search for your types).
Now suppose we want to add this type to another library types. (As my own situation). We can use some ts
keywords. And as long as VSCode understands ts
we have no problem with it.
For example if you want to add this view
function to response from expressjs, change index.d.ts
file as follows:
export declare global {
namespace Express {
interface Response {
/**
* Use express res.render function to render view file inside layout file.
*
* @param {string} view The path of the view file, relative to view root dir.
* @param {object} options The options to send to view file for ejs to use when rendering.
* @returns {Express.Response.render} .
*/
view(view: string, options?: object): Express.Response.render;
}
}
}
The full URL is available as request.url
, and the query string is available as request.query_string.decode()
.
Here's an example:
from flask import request
@app.route('/adhoc_test/')
def adhoc_test():
return request.query_string
To access an individual known param passed in the query string, you can use request.args.get('param')
. This is the "right" way to do it, as far as I know.
ETA: Before you go further, you should ask yourself why you want the query string. I've never had to pull in the raw string - Flask has mechanisms for accessing it in an abstracted way. You should use those unless you have a compelling reason not to.

Install yarn an then run
yarn global add install-peerdeps
The abs() in the while condition is needed, since, well, it controls the number of iterations (how would you define a negative number of iterations?). You can correct it by inverting the sign of the result if numb
is negative.
So this is the modified version of your code. Note I replaced the while loop with a cleaner for loop.
#get user input of numbers as variables
numa, numb = input("please give 2 numbers to multiply seperated with a comma:")
#standing variables
total = 0
#output the total
for count in range(abs(numb)):
total += numa
if numb < 0:
total = -total
print total
First, try omitting the quotes from 12 and 24. Worth a shot.
Second, it's better to do this in CSS. See also http://www.w3schools.com/css/css_font.asp . Here is an inline style for a table tag:
<table style='font-family:"Courier New", Courier, monospace; font-size:80%' ...>...</table>
Better still, use an external style sheet or a style tag near the top of your HTML document. See also http://www.w3schools.com/css/css_howto.asp .
On windows XP you get this error if postgres is not installed ...
Arrays are effectively passed by reference by default. Actually the value of the pointer to the first element is passed. Therefore the function or method receiving this can modify the values in the array.
void SomeMethod(Coordinate Coordinates[]){Coordinates[0].x++;};
int main(){
Coordinate tenCoordinates[10];
tenCoordinates[0].x=0;
SomeMethod(tenCoordinates[]);
SomeMethod(&tenCoordinates[0]);
if(0==tenCoordinates[0].x - 2;){
exit(0);
}
exit(-1);
}
The two calls are equivalent, and the exit value should be 0;

My problem was to put focus back on an ajax call that was modifying part of the form.
$.ajax({ url : "ajax_invite_load.php",
async : true,
type : 'POST',
data : ...
dataType : 'html',
success : function(html, statut) {
var focus = $(document.activeElement).getSelector();
$td_left.html(html);
$(focus).focus();
}
});
I just needed to encapsulate your function in a jQuery plugin:
!(function ($, undefined) {
$.fn.getSelector = function () {
if (!this || !this.length) {
return ;
}
function _getChildSelector(index) {
if (typeof index === 'undefined') {
return '';
}
index = index + 1;
return ':nth-child(' + index + ')';
}
function _getIdAndClassNames($el) {
var selector = '';
// attach id if exists
var elId = $el.attr('id');
if(elId){
selector += '#' + elId;
}
// attach class names if exists
var classNames = $el.attr('class');
if(classNames){
selector += '.' + classNames.replace(/^\s+|\s+$/g, '').replace(/\s/gi, '.');
}
return selector;
}
// get all parents siblings index and element's tag name,
// except html and body elements
var selector = this.parents(':not(html,body)')
.map(function() {
var parentIndex = $(this).index();
return this.tagName + _getChildSelector(parentIndex);
})
.get()
.reverse()
.join(' ');
if (selector) {
// get node name from the element itself
selector += ' ' + this[0].nodeName +
// get child selector from element ifself
_getChildSelector(this.index());
}
selector += _getIdAndClassNames(this);
return selector;
}
})(window.jQuery);
use JsonReader in order to parse the InputStream. See example inside the API: http://developer.android.com/reference/android/util/JsonReader.html
Use Invoke-RestMethod
to consume REST-APIs. Save the JSON to a string and use that as the body, ex:
$JSON = @'
{"@type":"login",
"username":"[email protected]",
"password":"yyy"
}
'@
$response = Invoke-RestMethod -Uri "http://somesite.com/oneendpoint" -Method Post -Body $JSON -ContentType "application/json"
If you use Powershell 3, I know there have been some issues with Invoke-RestMethod
, but you should be able to use Invoke-WebRequest
as a replacement:
$response = Invoke-WebRequest -Uri "http://somesite.com/oneendpoint" -Method Post -Body $JSON -ContentType "application/json"
If you don't want to write your own JSON every time, you can use a hashtable and use PowerShell to convert it to JSON before posting it. Ex.
$JSON = @{
"@type" = "login"
"username" = "[email protected]"
"password" = "yyy"
} | ConvertTo-Json
The %d
conversion specifier will only convert one decimal integer. It doesn't know that you're passing an array, it can't modify its behavior based on that. The conversion specifier specifies the conversion.
There is no specifier for arrays, you have to do it explicitly. Here's an example with four conversions:
if(scanf("%d %d %d %d", &array[0], &array[1], &array[2], &array[3]) == 4)
printf("got four numbers\n");
Note that this requires whitespace between the input numbers.
If the id is a single 11-digit number, it's best to treat as a string:
char id[12];
if(scanf("%11s", id) == 1)
{
/* inspect the *character* in id[0], compare with '1' or '2' for instance. */
}
For your purposes, if all the items are stored as str
and you just use sorted as you are using and then check for the first element and replace it with '0'
>>> l1 = ['88','NaN','67','89','81']
>>> n = sorted(l1,reverse=True)
['NaN', '89', '88', '81', '67']
>>> import math
>>> if math.isnan(float(n[0])):
... n[0] = '0'
...
>>> n
['0', '89', '88', '81', '67']
This is because Java Generics are implemented with Type Erasure.
Your methods would be translated, at compile time, to something like:
Method resolution occurs at compile time and doesn't consider type parameters. (see erickson's answer)
void add(Set ii);
void add(Set ss);
Both methods have the same signature without the type parameters, hence the error.
From the keytool man - it imports certificate chain, if input is given in PKCS#7 format, otherwise only the single certificate is imported. You should be able to convert certificates to PKCS#7 format with openssl, via openssl crl2pkcs7 command.
Recently I also find the same problem and there some reasons behind this but I am giving you 3
It must work.
I think there is a lot of confusion about which weights are used for what. I am not sure I know precisely what bothers you so I am going to cover different topics, bear with me ;).
The weights from the class_weight
parameter are used to train the classifier.
They are not used in the calculation of any of the metrics you are using: with different class weights, the numbers will be different simply because the classifier is different.
Basically in every scikit-learn classifier, the class weights are used to tell your model how important a class is. That means that during the training, the classifier will make extra efforts to classify properly the classes with high weights.
How they do that is algorithm-specific. If you want details about how it works for SVC and the doc does not make sense to you, feel free to mention it.
Once you have a classifier, you want to know how well it is performing.
Here you can use the metrics you mentioned: accuracy
, recall_score
, f1_score
...
Usually when the class distribution is unbalanced, accuracy is considered a poor choice as it gives high scores to models which just predict the most frequent class.
I will not detail all these metrics but note that, with the exception of accuracy
, they are naturally applied at the class level: as you can see in this print
of a classification report they are defined for each class. They rely on concepts such as true positives
or false negative
that require defining which class is the positive one.
precision recall f1-score support
0 0.65 1.00 0.79 17
1 0.57 0.75 0.65 16
2 0.33 0.06 0.10 17
avg / total 0.52 0.60 0.51 50
F1 score:/usr/local/lib/python2.7/site-packages/sklearn/metrics/classification.py:676: DeprecationWarning: The
default `weighted` averaging is deprecated, and from version 0.18,
use of precision, recall or F-score with multiclass or multilabel data
or pos_label=None will result in an exception. Please set an explicit
value for `average`, one of (None, 'micro', 'macro', 'weighted',
'samples'). In cross validation use, for instance,
scoring="f1_weighted" instead of scoring="f1".
You get this warning because you are using the f1-score, recall and precision without defining how they should be computed! The question could be rephrased: from the above classification report, how do you output one global number for the f1-score? You could:
avg / total
result above. It's also called macro averaging.'weighted'
in scikit-learn will weigh the f1-score by the support of the class: the more elements a class has, the more important the f1-score for this class in the computation.These are 3 of the options in scikit-learn, the warning is there to say you have to pick one. So you have to specify an average
argument for the score method.
Which one you choose is up to how you want to measure the performance of the classifier: for instance macro-averaging does not take class imbalance into account and the f1-score of class 1 will be just as important as the f1-score of class 5. If you use weighted averaging however you'll get more importance for the class 5.
The whole argument specification in these metrics is not super-clear in scikit-learn right now, it will get better in version 0.18 according to the docs. They are removing some non-obvious standard behavior and they are issuing warnings so that developers notice it.
Last thing I want to mention (feel free to skip it if you're aware of it) is that scores are only meaningful if they are computed on data that the classifier has never seen. This is extremely important as any score you get on data that was used in fitting the classifier is completely irrelevant.
Here's a way to do it using StratifiedShuffleSplit
, which gives you a random splits of your data (after shuffling) that preserve the label distribution.
from sklearn.datasets import make_classification
from sklearn.cross_validation import StratifiedShuffleSplit
from sklearn.metrics import accuracy_score, f1_score, precision_score, recall_score, classification_report, confusion_matrix
# We use a utility to generate artificial classification data.
X, y = make_classification(n_samples=100, n_informative=10, n_classes=3)
sss = StratifiedShuffleSplit(y, n_iter=1, test_size=0.5, random_state=0)
for train_idx, test_idx in sss:
X_train, X_test, y_train, y_test = X[train_idx], X[test_idx], y[train_idx], y[test_idx]
svc.fit(X_train, y_train)
y_pred = svc.predict(X_test)
print(f1_score(y_test, y_pred, average="macro"))
print(precision_score(y_test, y_pred, average="macro"))
print(recall_score(y_test, y_pred, average="macro"))
Hope this helps.
If it is SQL Server you must drop the constraint before you can drop the table.
This returns like 11:30 AM
select CONVERT(VARCHAR(5), FromTime, 108) + ' ' + RIGHT(CONVERT(VARCHAR(30), FromTime, 9),2)
from tablename
In my case, and I had bad lag doing the simplest of things, it helped to update my pc drivers. The system drivers are the foundation for everything.
I was fortunate that I have Dell and they have awesome website support to do this. I googled
dell <my model name> update drivers
or go to the drivers home page
I let it update all the drivers it wanted to (Dell driver update is pretty much automatic).
Much of the lag seems to have gone away.
Also, in addition to torek's answer: one thing that stands out is that you're using a lazily-evaluated macro assignment.
If you're on GNU Make, use the :=
assignment instead of =
. This assignment causes the right hand side to be expanded immediately, and stored in the left hand variable.
FILES := $(shell ...) # expand now; FILES is now the result of $(shell ...)
FILES = $(shell ...) # expand later: FILES holds the syntax $(shell ...)
If you use the =
assignment, it means that every single occurrence of $(FILES)
will be expanding the $(shell ...)
syntax and thus invoking the shell command. This will make your make job run slower, or even have some surprising consequences.
This is not an error. This is a warning. The difference is pretty huge. This particular warning basically means that the <Context>
element in Tomcat's server.xml
contains an unknown attribute source
and that Tomcat doesn't know what to do with this attribute and therefore will ignore it.
Eclipse WTP adds a custom attribute source
to the project related <Context>
element in the server.xml
of Tomcat which identifies the source of the context (the actual project in the workspace which is deployed to the particular server). This way Eclipse can correlate the deployed webapplication with an project in the workspace. Since Tomcat version 6.0.16, any unspecified XML tags and attributes in the server.xml
will produce a warning during Tomcat's startup, even though there is no DTD nor XSD for server.xml
.
Just ignore it. Your web project is fine. It should run fine. This issue is completely unrelated to JSF.
I think this question needs an updated answer, because both PostgreSQL and SQLDeveloper have been updated several times since it was originally asked.
I've got a PostgreSQL instance running in Azure, with SSLMODE=Require. While I've been using DBeaverCE to access that instance and generate an ER Diagram, I've gotten really familiar with SQLDeveloper, which is now at v19.4.
The instructions about downloading the latest PostgreSQL JDBC driver and where to place it are correct. What has changed, though, is where to configure your DB access.
You'll find a file $HOME/.sqldeveloper/system19.4.0.354.1759/o.jdeveloper.db.connection.19.3.0.354.1759/connections.json
:
{
"connections": [
{
"name": "connection-name-goes-here",
"type": "jdbc",
"info": {
"customUrl": "jdbc:postgresql://your-postgresql-host:5432/DBNAME?sslmode=require",
"hostname": "your-postgresql-host",
"driver": "org.postgresql.Driver",
"subtype": "SDPostgreSQL",
"port": "5432",
"SavePassword": "false",
"RaptorConnectionType": "SDPostgreSQL",
"user": "your_admin_user",
"sslmode": "require"
}
}
]
}
You can use this connection with both Data Modeller and the admin functionality of SQLDeveloper. Specifying all the port, dbname and sslmode in the customUrl are required because SQLDeveloper isn't including the sslmode in what it sends via JDBC, so you have to construct it by hand.
You cannot animate two things (like zoom in and go to my location) in one google map?
From a coding standpoint, you would do them sequentially:
CameraUpdate center=
CameraUpdateFactory.newLatLng(new LatLng(40.76793169992044,
-73.98180484771729));
CameraUpdate zoom=CameraUpdateFactory.zoomTo(15);
map.moveCamera(center);
map.animateCamera(zoom);
Here, I move the camera first, then animate the camera, though both could be animateCamera()
calls. Whether GoogleMap
consolidates these into a single event, I can't say, as it goes by too fast. :-)
Here is the sample project from which I pulled the above code.
Sorry, this answer is flawed. See Rob's answer for a way to truly do this in one shot, by creating a CameraPosition
and then creating a CameraUpdate
from that CameraPosition
.
var SendInfo= { SendInfo: [... your elements ...]};
$.ajax({
type: 'post',
url: 'Your-URI',
data: JSON.stringify(SendInfo),
contentType: "application/json; charset=utf-8",
traditional: true,
success: function (data) {
...
}
});
and in action
public ActionResult AddDomain(IEnumerable<PersonSheets> SendInfo){
...
you can bind your array like this
var SendInfo = [];
$(this).parents('table').find('input:checked').each(function () {
var domain = {
name: $("#id-manuf-name").val(),
address: $("#id-manuf-address").val(),
phone: $("#id-manuf-phone").val(),
}
SendInfo.push(domain);
});
hope this can help you.
The Java Language Specification, section 15.10, states:
An array creation expression creates an object that is a new array whose elements are of the type specified by the PrimitiveType or ClassOrInterfaceType. It is a compile-time error if the ClassOrInterfaceType does not denote a reifiable type (§4.7).
and
The rules above imply that the element type in an array creation expression cannot be a parameterized type, other than an unbounded wildcard.
The closest you can do is use an unchecked cast, either from the raw type, as you have done, or from an unbounded wildcard:
HashMap<String, String>[] responseArray = (Map<String, String>[]) new HashMap<?,?>[games.size()];
Your version is clearly better :-)
I found this method worked for me:
$thisproduct = "my_product_id";
$array=array("$product1", "$product2", "$product3", "$product4");
if (in_array($thisproduct,$array)) {
echo "Product found";
}
Regarding your final bullet

I know that OP asked for Angular 5 solution, but yet for all of you who stumbles upon this question for newer (6+) Angular versions. Citing the Docs, regarding ActivatedRoute.queryParams (which most of other answers are based on):
Two older properties are still available. They are less capable than their replacements, discouraged, and may be deprecated in a future Angular version.
params — An Observable that contains the required and optional parameters specific to the route. Use paramMap instead.
queryParams — An Observable that contains the query parameters available to all routes. Use queryParamMap instead.
According to the Docs, the simple way to get the query params would look like this:
constructor(private route: ActivatedRoute) { }
ngOnInit() {
this.param1 = this.route.snapshot.paramMap.get('param1');
this.param2 = this.route.snapshot.paramMap.get('param2');
}
For more advanced ways (e.g. advanced component re-usage) see this Docs chapter.
EDIT:
As it correctly stated in comments below, this answer is wrong - at least for the case specified by OP.
OP asks to get global query parameters (/app?param1=hallo¶m2=123); in this case you should use queryParamMap (just like in @dapperdan1985 answer).
paramMap, on the other hand, is used on parameters specific to the route (e.g. /app/:param1/:param2, resulting in /app/hallo/123).
Thanks to @JasonRoyle and @daka for pointing it out.
If you dont need to pass arguments, then initializer code is enough, but if you need to pass arguments from a contrcutor there is a way to solve most of the cases:
Boolean var= new anonymousClass(){
private String myVar; //String for example
@Overriden public Boolean method(int i){
//use myVar and i
}
public String setVar(String var){myVar=var; return this;} //Returns self instane
}.setVar("Hello").method(3);
let's suppose
x=50
y=5
then
z=$((x/y))
this will work properly . But if you want to use / operator in case statements than it can't resolve it. In that case use simple strings like div or devide or something else. See the code
This can also happen if you have this restriction:
Please enter the commit message for your changes. Lines starting with '#' will be ignored, and an empty message aborts the commit.
and you do like me: write a commit message starting with "#" .....
I had the same error, but I already had the commit-msg
and did the rebase
and everything. Very silly mistake though :D
A tip to all people that use flat-red, flat-green plugin, because of this plugin the answers above wont work!
In that case, use onchange="do_your_stuff();" on the label, for example: Your checkbox here
The reason why it doesn't work is that this Jquery creates a lot of objects around the real checkbox, so you can't see if it's changed or not.
But if someone click straight on checkbox, won't work :'(
I got the same trouble since nearly release, seem must use KUBECONFIG explicit

I know this is old but I came upon this post quickly thinking Concat would be my answer. Union worked great for me. Note, it returns only unique values but knowing that I was getting unique values anyway this solution worked for me.
namespace TestProject
{
public partial class Form1 :Form
{
public Form1()
{
InitializeComponent();
List<string> FirstList = new List<string>();
FirstList.Add("1234");
FirstList.Add("4567");
// In my code, I know I would not have this here but I put it in as a demonstration that it will not be in the secondList twice
FirstList.Add("Three");
List<string> secondList = GetList(FirstList);
foreach (string item in secondList)
Console.WriteLine(item);
}
private List<String> GetList(List<string> SortBy)
{
List<string> list = new List<string>();
list.Add("One");
list.Add("Two");
list.Add("Three");
list = list.Union(SortBy).ToList();
return list;
}
}
}
The output is:
One
Two
Three
1234
4567

On a Mac I (finally) successfully installed opencv from source using the following commands:
cmake -D CMAKE_BUILD_TYPE=RELEASE
-D CMAKE_INSTALL_PREFIX=/usr/local
-D PYTHON_EXECUTABLE=/Library/Frameworks/Python.framework/Versions/3.4/bin/python3
-D PYTHON_LIBRARY=/Library/Frameworks/Python.framework//Versions/3.4/lib/libpython3.4m.dylib
-D PYTHON_INCLUDE_DIR=/Library/Frameworks/Python.framework/Versions/3.4/include/python3.4m
-D PYTHON_NUMPY_INCLUDE_DIRS=/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/numpy/core/include/numpy
-D PYTHON_PACKAGES_PATH=/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages
/relative/path/to/source/directory/
Then,
make -j8
change 8 for the number of threads your machine can handle, to speed things up
sudo make install
I added a PYTHONPATH
environment variable to my ~/.bash_profile
file so that Python could find cv2.so
:
PYTHONPATH="${PYTHONPATH}:/usr/local/lib/python3.4/site-packages”
export PYTHONPATH
[For those using PyCharm, I had to go to Preferences > Project Structure > Add Content Root, and added the path to cv2.so
's parent directory: /usr/local/lib/python3.4/site-packages
]
This command got me past errors such as:
Could NOT find PythonLibs
, by explicitly declaring the python library path
ld: can't link with a main executable for architecture x86_64
collect2: error: ld returned 1 exit status
make[2]: *** [lib/cv2.so] Error 1
make[1]: *** [modules/python2/CMakeFiles/opencv_python2.dir/all] Error 2
make: *** [all] Error 2
by explicitly pointing to the libpython3.4m.dylib
In terminal, check that it worked with:
$python3
>>> import cv2
It's all good if you don't get ImportError: No module named 'cv2'
This worked on a Macbook Pro Retina 15" 2013, Mavericks 10.9.4, Python 3.4.1 (previously installed from official download), opencv3 from source. Hope that this helps someone.
I know this is an old post but, I've always used an updater extension method:
public static void Update<TSource>(this IEnumerable<TSource> outer, Action<TSource> updator)
{
foreach (var item in outer)
{
updator(item);
}
}
list.Where(w => w.Name == "height").ToList().Update(u => u.height = 30);
Yes you can add a callback function to any DOM insertion:
$myDiv.append( function(index_myDiv, HTML_myDiv){
//....
return child
})
Check on JQuery documentation: http://api.jquery.com/append/
And here's a practical, similar, example:
http://www.w3schools.com/jquery/tryit.asp?filename=tryjquery_html_prepend_func
According to the create table statement, the default charset of the table is already utf8mb4. It seems that you have a wrong connection charset.
In Java, set the datasource url like this: jdbc:mysql://127.0.0.1:3306/testdb?useUnicode=true&characterEncoding=utf-8.
"?useUnicode=true&characterEncoding=utf-8" is necessary for using utf8mb4.
It works for my application.
Assuming the application you are attempting to run in the background is CLI based, you can try calling the scheduled jobs using Hidden Start

You can use django-model-changes to do this without an additional database lookup:
from django.dispatch import receiver
from django_model_changes import ChangesMixin
class Alias(ChangesMixin, MyBaseModel):
# your model
@receiver(pre_save, sender=Alias)
def do_something_if_changed(sender, instance, **kwargs):
if 'remote_image' in instance.changes():
# do something
You need to use:
await client.PostAsync(uri, content);
Something like that:
var comment = "hello world";
var questionId = 1;
var formContent = new FormUrlEncodedContent(new[]
{
new KeyValuePair<string, string>("comment", comment),
new KeyValuePair<string, string>("questionId", questionId)
});
var myHttpClient = new HttpClient();
var response = await myHttpClient.PostAsync(uri.ToString(), formContent);
And if you need to get the response after post, you should use:
var stringContent = await response.Content.ReadAsStringAsync();
Hope it helps ;)

SQL is a declarative language, not a procedural language. That is, you construct a SQL statement to describe the results that you want. You are not telling the SQL engine how to do the work.
As a general rule, it is a good idea to let the SQL engine and SQL optimizer find the best query plan. There are many person-years of effort that go into developing a SQL engine, so let the engineers do what they know how to do.
Of course, there are situations where the query plan is not optimal. Then you want to use query hints, restructure the query, update statistics, use temporary tables, add indexes, and so on to get better performance.
As for your question. The performance of CTEs and subqueries should, in theory, be the same since both provide the same information to the query optimizer. One difference is that a CTE used more than once could be easily identified and calculated once. The results could then be stored and read multiple times. Unfortunately, SQL Server does not seem to take advantage of this basic optimization method (you might call this common subquery elimination).
Temporary tables are a different matter, because you are providing more guidance on how the query should be run. One major difference is that the optimizer can use statistics from the temporary table to establish its query plan. This can result in performance gains. Also, if you have a complicated CTE (subquery) that is used more than once, then storing it in a temporary table will often give a performance boost. The query is executed only once.
The answer to your question is that you need to play around to get the performance you expect, particularly for complex queries that are run on a regular basis. In an ideal world, the query optimizer would find the perfect execution path. Although it often does, you may be able to find a way to get better performance.
It is possible to start an app's activity by using Intent.setClassName
according to the docs.
An example:
val activityName = "com.google.android.apps.muzei.MuzeiActivity" // target activity name
val packageName = "net.nurik.roman.muzei" // target package's name
val intent = Intent().setClassName(packageName, activityName)
startActivity(intent)
To open it outside the current app, add this flag before starting the intent.
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)

Absolute:
The browser will always interpret /
as the root of the hostname. For example, if my site was http://google.com/
and I specified /css/images.css
then it would search for that at http://google.com/css/images.css
. If your project root was actually at /myproject/
it would not find the css file. Therefore, you need to determine where your project folder root is relative to the hostname, and specify that in your href
notation.
Relative: If you want to reference something you know is in the same path on the url - that is, if it is in the same folder, for example http://mysite.com/myUrlPath/index.html
and http://mysite.com/myUrlPath/css/style.css
, and you know that it will always be this way, you can go against convention and specify a relative path by not putting a leading /
in front of your path, for example, css/style.css
.
Filesystem Notations: Additionally, you can use standard filesystem notations like ..
. If you do http://google.com/images/../images/../images/myImage.png
it would be the same as http://google.com/images/myImage.png
. If you want to reference something that is one directory up from your file, use ../myFile.css
.
In your case, you have two options:
<link rel="stylesheet" type="text/css" href="/ServletApp/css/styles.css"/>
<link rel="stylesheet" type="text/css" href="css/styles.css"/>
The first will be more concrete and compatible if you move things around, however if you are planning to keep the file in the same location, and you are planning to remove the /ServletApp/ part of the URL, then the second solution is better.
Or, in your ~/.bashrc file:
function watch {
while :; do clear; date; echo; $@; sleep 2; done
}
i suggest in Javascript:
var item=1387843200000;
var date1=new Date(item);
and then date1 is a Date.
Real path for Support Repository Libraries:
If the problem still exists:
Go to the real path of your Support Repository Libraries and check that the following folder exists:
"ANDROID_SDK_DIRECTORY\extras\android\m2repository\com\android\support"
In that folder there are support libraries that can't be found. for example:
"ANDROID_SDK_DIRECTORY\extras\android\m2repository\com\android\support\appcompat-v7"
Open folder appcompat-v7
and you see folders with all available version. You should use only one of these versions in the build.gradle file dependencies or use +, for ex. 18.0.+
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:18.0.+'
compile 'com.android.support:gridlayout-v7:23.1.1'
compile 'com.android.support:support-v4:23.1.1'
}
That is the path taken from grade.build dependencies file:
com.android.support:appcompat-v7:18.0.0
Refer to the real path on your HDD -->
ANDROID_SDK_DIRECTORY\extras\android\m2repository\com\android\support\appcompat-v7\18.0.0
If there is no such folder, you will receive the error:
"failed to resolve com.android.support:appcompat-v7:18.0.0"
p.s. If you have Windows x64, when installing sdk and jdk, make sure that the installation path does not have Program Files(86)
. Brackets that add Windows may cause additional problems with resolving paths for your project. Use simple paths for your installation folder.
For example:
c:\androidSDK\
Path is often null. This function is safer.

In response to Mike B, I prefer to use 'class' as, within a template, 'typename' has an overloaded meaning, but 'class' does not. Take this checked integer type example:
template <class IntegerType>
class smart_integer {
public:
typedef integer_traits<Integer> traits;
IntegerType operator+=(IntegerType value){
typedef typename traits::larger_integer_t larger_t;
larger_t interm = larger_t(myValue) + larger_t(value);
if(interm > traits::max() || interm < traits::min())
throw overflow();
myValue = IntegerType(interm);
}
}
larger_integer_t
is a dependent name, so it requires 'typename' to preceed it so that the parser can recognize that larger_integer_t
is a type. class, on the otherhand, has no such overloaded meaning.
That... or I'm just lazy at heart. I type 'class' far more often than 'typename', and thus find it much easier to type. Or it could be a sign that I write too much OO code.
Indeed, there is no defined standard. To support that information, have a look at wikipedia, in the Query String chapter. There is the following comment:
While there is no definitive standard, most web frameworks allow multiple values to be associated with a single field.[3][4]
Furthermore, when you take a look at the RFC 3986, in section 3.4 Query, there is no definition for parameters with multiple values.
Most applications use the first option you have shown: http://server/action?id=a&id=b
. To support that information, take a look at this Stackoverflow link, and this MSDN link regarding ASP.NET applications, which use the same standard for parameters with multiple values.
However, since you are developing the APIs, I suggest you to do what is the easiest for you, since the caller of the API will not have much trouble creating the query string.
If you are using the VSCodeVim
extension, you can use the Vim key shortcuts:
Next tab: gt
Prior tab: gT
Numbered tab: nnngt
Here's how I got rid of mine:
.main .row .thumbnail {
display: inline-block;
border: 0px;
background-color: transparent;
}
Open a windows command line. Switch directories to C:\Windows\Microsoft.Net\Framework\v4.0.xxxx
where the x's are the build number. Type aspnet_regiis -ir
and hit enter. This should register .Net v4.0 and create the application pools by default. If it doesn't, you will need to create them manually by right-clicking the Application Pools
folder in IIS and choosing Add Application Pool
.
Edit: As a reference, please refer to the section of the linked document referring to the -i argument.
This is my way i do comments (I think its secure):
<h1>Comment's:</h1>
<?php
$i = addslashes($_POST['a']);
$ip = addslashes($_POST['b']);
$a = addslashes($_POST['c']);
$b = addslashes($_POST['d']);
if(isset($i) & isset($ip) & isset($a) & isset($b))
{
$r = mysql_query("SELECT COUNT(*) FROM $db.ban WHERE ip=$ip"); //Check if banned
$r = mysql_fetch_array($r);
if(!$r[0]) //Phew, not banned
{
if(mysql_query("INSERT INTO $db.com VALUES ($a, $b, $ip, $i)"))
{
?>
<script type="text/javascript">
window.location="/index.php?id=".<?php echo $i; ?>;
</script>
<?php
}
else echo "Error, in mysql query";
}
else echo "Error, You are banned.";
}
$x = mysql_query("SELECT * FROM $db.com WHERE i=$i");
while($r = mysql_fetch_object($x) echo '<div class="c">'.$r->a.'<p>'.$row->b.'</p> </div>';
?>
<h1>Leave a comment, pl0x:</h1>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
<input type="hidden" name="a" value="<?php $echo $_GET['id']; ?>" />
<input type="hidden" name="b" value="<?php $echo $_SERVER['REMOTE_ADDR']; ?>" />
<input type="text" name="c" value="Name"/></br>
<textarea name="d">

<input type="submit" />
</form>
This does it all in one page (This is only the comments section, some configuration is needed)
Why do you use new Date instead of a static UTC string?
function clearListCookies(){
var cookies = document.cookie.split(";");
for (var i = 0; i < cookies.length; i++){
var spcook = cookies[i].split("=");
document.cookie = spcook[0] + "=;expires=Thu, 21 Sep 1979 00:00:01 UTC;";
}
}
You could use the substring and concatenation for easy formatting too.
telephoneNumber = "("+telephoneNumber.substring(0, 3)+")-"+telephoneNumber.substring(3, 6)+"-"+telephoneNumber.substring(6, 10);
But one thing to note is that you must check for the lenght of the telephone number field just to make sure that your formatting is safe.
Regarding the alternative to super; you'd in most cases use use the base class either in the initialization list of the derived class, or using the Base::someData
syntax when you are doing work elsewhere and the derived class redefines data members.
struct Base
{
Base(char* name) { }
virtual ~Base();
int d;
};
struct Derived : Base
{
Derived() : Base("someString") { }
int d;
void foo() { d = Base::d; }
};
Model
[Required(ErrorMessage = "You must provide a phone number")]
[Display(Name = "Home Phone")]
[DataType(DataType.PhoneNumber)]
[RegularExpression(@"^\(?([0-9]{3})\)?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$", ErrorMessage = "Not a valid phone number")]
public string PhoneNumber { get; set; }
View:
@Html.LabelFor(model => model.PhoneNumber)
@Html.EditorFor(model => model.PhoneNumber)
@Html.ValidationMessageFor(model => model.PhoneNumber)
Sometimes this error also appears when you have a var or a let that hasn't been intialized.
For example
class ViewController: UIViewController {
var x: Double
// or
var y: String
// or
let z: Int
}
Depending on what your variable is supposed to do you might either set that var type as an optional or initialize it with a value like the following
class ViewController: UIViewCOntroller {
// Set an initial value for the variable
var x: Double = 0
// or an optional String
var y: String?
// or
let z: Int = 2
}
The basic answer is: you need to iterate through loop and check any element contains the specified string. So, let's say the code is:
foreach(string item in myList)
{
if(item.Contains(myString))
return item;
}
The equivalent, but terse, code is:
mylist.Where(x => x.Contains(myString)).FirstOrDefault();
Here, x is a parameter that acts like "item" in the above code.
Careful when running
export GOPATH=$HOME
Go assume that your code exists in specific places related to GOPATH
. So, instead, you can use docker to run any go command:
docker run -it -v $(pwd):/go/src/github.com/<organization name>/<repository name> golang
And now you can use any golang command, for example:
go test github.com/<organization name>/<repository name>
Here's a comparison of four different algorithms for accomplishing this: https://jsperf.com/sorted-array-insert-comparison/1
Algorithms
Naive is always horrible. It seems for small array sizes, the other three dont differ too much, but for larger arrays, the last 2 outperform the simple linear approach.
Works fine too:
/* small screen portrait */
@media (max-width: 321px) {
.pull-right {
float: none!important;
}
}
/* small screen lanscape */
@media (max-width: 480px) {
.pull-right {
float: none!important;
}
}
If you want greater control you can use javascript rather than use the meta tag. This would allow you to have a visual of some kind, e.g. a countdown.
Here is a very basic approach using setTimeout()
<html>_x000D_
<body>_x000D_
<p>You will be redirected in 3 seconds</p>_x000D_
<script>_x000D_
var timer = setTimeout(function() {_x000D_
window.location='http://example.com'_x000D_
}, 3000);_x000D_
</script>_x000D_
</body>_x000D_
</html>
_x000D_
You cannot instantiate an interface - you must provide a concrete implementation of IEnumerable.
Or in your SQL query wrap that field with IsNull or Coalesce (SQL Server).
Either way works, I like to put that logic in the query so the report has to do less.
Assuming you're not writing a rubygem, Gemfile.lock should be in your repository. It's used as a snapshot of all your required gems and their dependencies. This way bundler doesn't have to recalculate all the gem dependencies each time you deploy, etc.
From cowboycoded's comment below:
If you are working on a gem, then DO NOT check in your Gemfile.lock. If you are working on a Rails app, then DO check in your Gemfile.lock.
Here's a nice article explaining what the lock file is.
Normally Python throws NameError
if the variable is not defined:
>>> d[0]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'd' is not defined
However, you've managed to stumble upon a name that already exists in Python.
Because dict
is the name of a built-in type in Python you are seeing what appears to be a strange error message, but in reality it is not.
The type of dict
is a type
. All types are objects in Python. Thus you are actually trying to index into the type
object. This is why the error message says that the "'type' object is not subscriptable."
>>> type(dict)
<type 'type'>
>>> dict[0]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'type' object is not subscriptable
Note that you can blindly assign to the dict
name, but you really don't want to do that. It's just going to cause you problems later.
>>> dict = {1:'a'}
>>> type(dict)
<class 'dict'>
>>> dict[1]
'a'
The true source of the problem is that you must assign variables prior to trying to use them. If you simply reorder the statements of your question, it will almost certainly work:
d = {1: "walk1.png", 2: "walk2.png", 3: "walk3.png"}
m1 = pygame.image.load(d[1])
m2 = pygame.image.load(d[2])
m3 = pygame.image.load(d[3])
playerxy = (375,130)
window.blit(m1, (playerxy))
Try looking at the return value of execute
, which is TRUE
on success, and FALSE
on failure.
I wanted the new application start up after the old one shuts down.
Using process.WaitForExit() to wait for your own process to shutdown makes no sense. It will always time out.
So, my approach is to use Application.Exit() then wait, but allow events to be processed, for a period of time. Then start a new application with the same arguments as the old.
static void restartApp() {
string commandLineArgs = getCommandLineArgs();
string exePath = Application.ExecutablePath;
try {
Application.Exit();
wait_allowingEvents( 1000 );
} catch( ArgumentException ex ) {
throw;
}
Process.Start( exePath, commandLineArgs );
}
static string getCommandLineArgs() {
Queue<string> args = new Queue<string>( Environment.GetCommandLineArgs() );
args.Dequeue(); // args[0] is always exe path/filename
return string.Join( " ", args.ToArray() );
}
static void wait_allowingEvents( int durationMS ) {
DateTime start = DateTime.Now;
do {
Application.DoEvents();
} while( start.Subtract( DateTime.Now ).TotalMilliseconds > durationMS );
}
The right thing would be to use a "if defined" statement, which is used to test for the existence of a variable. For example:
IF DEFINED somevariable echo Value exists
In this particular case, the negative form should be used:
IF NOT DEFINED somevariable echo Value missing
PS: the variable name should be used without "%" caracters.
The answer is no. Keep in mind that in both cases, mdDate.Kind = DateTimeKind.Unspecified
.
Therefore it may be better to do the following:
DateTime myDate = new DateTime(1, 1, 1, 0, 0, 0, DateTimeKind.Utc);
The myDate.Kind
property is readonly, so it cannot be changed after the constructor is called.
The following code works for me.
//escape the double quotes in json string
String payload="{\"jsonrpc\":\"2.0\",\"method\":\"changeDetail\",\"params\":[{\"id\":11376}],\"id\":2}";
String requestUrl="https://git.eclipse.org/r/gerrit/rpc/ChangeDetailService";
sendPostRequest(requestUrl, payload);
method implementation:
public static String sendPostRequest(String requestUrl, String payload) {
try {
URL url = new URL(requestUrl);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setRequestMethod("POST");
connection.setRequestProperty("Accept", "application/json");
connection.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
OutputStreamWriter writer = new OutputStreamWriter(connection.getOutputStream(), "UTF-8");
writer.write(payload);
writer.close();
BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream()));
StringBuffer jsonString = new StringBuffer();
String line;
while ((line = br.readLine()) != null) {
jsonString.append(line);
}
br.close();
connection.disconnect();
return jsonString.toString();
} catch (Exception e) {
throw new RuntimeException(e.getMessage());
}
}
After trying the above suggestions, the only thing that worked for me was changing the border attribute to "0" in the following sections of a child theme's style.css (do a "Find" operation to locate each one -- the following are just snippets):
.comment-content table {
border-bottom: 1px solid #ddd;
.comment-content td {
border-top: 1px solid #ddd;
padding: 6px 10px 6px 0;
}
Thus looking like this afterwards:
.comment-content table {
border-bottom: 0;
.comment-content td {
border-top: 0;
padding: 6px 10px 6px 0;
}
There are two primary contenders for python apps on Android
This integrates with the Android build system, it provides a Python API for all android features. To quote the site "The complete Android API and user interface toolkit are directly at your disposal."
This provides a multi target transpiler, supports many targets such as Android and iOS. It uses a generic widget toolkit (toga) that maps to the host interface calls.
Both are active projects and their github accounts shows a fair amount of recent activity.
Beeware Toga like all widget libraries is good for getting the basics out to multiple platforms. If you have basic designs, and a desire to expand to other platforms this should work out well for you.
On the other hand, Chaquopy is a much more precise in its mapping of the python API to Android. It also allows you to mix in Java, useful if you want to use existing code from other resources. If you have strict design targets, and predominantly want to target Android this is a much better resource.
git commit (file name with path which you want to delete) -m "file is deleted"
git push
It will work.Multiple selective file also you can delete in remote repository same way.
You can do this really easily in Twisted. Depending upon your existing code base, this might not be that easy to use, but if you are building a twisted application, then things like this become almost trivial. You create a ProcessProtocol
class, and override the outReceived()
method. Twisted (depending upon the reactor used) is usually just a big select()
loop with callbacks installed to handle data from different file descriptors (often network sockets). So the outReceived()
method is simply installing a callback for handling data coming from STDOUT
. A simple example demonstrating this behavior is as follows:
from twisted.internet import protocol, reactor
class MyProcessProtocol(protocol.ProcessProtocol):
def outReceived(self, data):
print data
proc = MyProcessProtocol()
reactor.spawnProcess(proc, './myprogram', ['./myprogram', 'arg1', 'arg2', 'arg3'])
reactor.run()
The Twisted documentation has some good information on this.
If you build your entire application around Twisted, it makes asynchronous communication with other processes, local or remote, really elegant like this. On the other hand, if your program isn't built on top of Twisted, this isn't really going to be that helpful. Hopefully this can be helpful to other readers, even if it isn't applicable for your particular application.
The answers didn't work for me with postgresql 9.1+
This is what I had to do (you can check more in the manual here)
UPDATE schema.TableA as A
SET "columnA" = "B"."columnB"
FROM schema.TableB as B
WHERE A.id = B.id;
You can omit the schema, if you are using the default schema for both tables.
A recent attempt to port Objective C 2.0 to Windows is the Subjective project.
From the Readme:
Subjective is an attempt to bring Objective C 2.0 with ARC support to Windows.
This project is a fork of objc4-532.2, the Objective C runtime that ships with OS X 10.8.5. The port can be cross-compiled on OS X using llvm-clang combined with the MinGW linker.
There are certain limitations many of which are a matter of extra work, while others, such as exceptions and blocks, depend on more serious work in 3rd party projects. The limitations are:
• 32-bit only - 64-bit is underway
• Static linking only - dynamic linking is underway
• No closures/blocks - until libdispatch supports them on Windows
• No exceptions - until clang supports them on Windows
• No old style GC - until someone cares...
• Internals: no vtables, no gdb support, just plain malloc, no preoptimizations - some of these things will be available under the 64-bit build.
• Currently a patched clang compiler is required; the patch adds -fobjc-runtime=subj flag
The project is available on Github, and there is also a thread on the Cocotron Group outlining some of the progress and issues encountered.
I think it should be
verify(mockBar, times(2)).doSomething(...)
Sample from mockito javadoc:
ArgumentCaptor<Person> peopleCaptor = ArgumentCaptor.forClass(Person.class);
verify(mock, times(2)).doSomething(peopleCaptor.capture());
List<Person> capturedPeople = peopleCaptor.getAllValues();
assertEquals("John", capturedPeople.get(0).getName());
assertEquals("Jane", capturedPeople.get(1).getName());
You can use the listFiles()
method provided by the java.io.File
class.
import java.io.File;
import java.io.FilenameFilter;
public class Filter {
public File[] finder( String dirName){
File dir = new File(dirName);
return dir.listFiles(new FilenameFilter() {
public boolean accept(File dir, String filename)
{ return filename.endsWith(".txt"); }
} );
}
}
To get it into a variable, the easiest way is:
export GIT_REV_COUNT=`git rev-list --all --count`
Use Mockito's doThrow and then catch the desired exception to assert it was thrown later.
@Test
public void fooShouldThrowMyException() {
// given
val myClass = new MyClass();
val arg = mock(MyArgument.class);
doThrow(MyException.class).when(arg).argMethod(any());
Exception exception = null;
// when
try {
myClass.foo(arg);
} catch (MyException t) {
exception = t;
}
// then
assertNotNull(exception);
}

Material desing buttons add to button xml:
style="@style/Widget.MaterialComponents.Button.UnelevatedButton"
Are you committing the cell before pressing the button (pressing Enter)? The contents of the cell must be stored before it can be used to name a sheet.
A better way to do this is to pop up a dialog box and get the name you wish to use.
try this :
if (file_exists(FCPATH . 'uploads/pages/' . $image)) {
unlink(FCPATH . 'uploads/pages/' . $image);
}
This was helpful for me, if you use the
var dir = Directory.GetCurrentDirectory()
the path fill be beyond the current folder, it will incluide this path \bin\debug What I recommend you, is that you can use the
string dir = Directory.GetParent(Directory.GetCurrentDirectory()).Parent.Parent.FullName
then print the dir value and verify the path is giving you
This script provides a Perl-like command line interface:
Pyliner - Script to run arbitrary Python code on the command line (Python recipe)
It's not entirely clear from your question whether you want a logged x-axis or a logged y-axis. A logged y-axis is not a good idea when using bars because they are anchored at zero, which becomes negative infinity when logged. You can work around this problem by using a frequency polygon or density plot.
Necromancing.
Also, the method by bzlm can be used to remove characters that are not in an arbitrary charset, not just ASCII:

For anyone looking for a complete explanation, I recommend you to take a look at Content Security Policy: https://www.html5rocks.com/en/tutorials/security/content-security-policy/.
"Code from https://mybank.com should only have access to https://mybank.com’s data, and https://evil.example.com should certainly never be allowed access. Each origin is kept isolated from the rest of the web"
XSS attacks are based on the browser's inability to distinguish your app's code from code downloaded from another website. So you must whitelist the content origins that you consider safe to download content from, using the Content-Security-Policy
HTTP header.
This policy is described using a series of policy directives, each of which describes the policy for a certain resource type or policy area. Your policy should include a default-src policy directive, which is a fallback for other resource types when they don't have policies of their own.
So, if you modify your tag to:
<meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval'; style-src 'self' 'unsafe-inline'; media-src *;**script-src 'self' http://onlineerp.solution.quebec 'unsafe-inline' 'unsafe-eval';** ">
You are saying that you are authorizing the execution of JavaScript code (script-src
)
from the origins 'self'
, http://onlineerp.solution.quebec
, 'unsafe-inline'
, 'unsafe-eval'
.
I guess that the first two are perfectly valid for your use case, I am a bit unsure about the other ones. 'unsafe-line'
and 'unsafe-eval'
pose a security problem, so you should not be using them unless you have a very specific need for them:
"If eval and its text-to-JavaScript brethren are completely essential to your application, you can enable them by adding 'unsafe-eval' as an allowed source in a script-src directive. But, again, please don’t. Banning the ability to execute strings makes it much more difficult for an attacker to execute unauthorized code on your site." (Mike West, Google)

Do you really need to do that programmatically?
Just considering the title: You could use a ShapeDrawable as android:background…
For example, let's define res/drawable/my_custom_background.xml
as:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners

and define android:background="@drawable/my_custom_background".
I've not tested but it should work.
Update:
I think that's better to leverage the xml shape drawable resource power if that fits your needs. With a "from scratch" project (for android-8), define res/layout/main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/border"
android:padding="10dip" >
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Hello World, SOnich"
/>
[... more TextView ...]
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Hello World, SOnich"
/>
</LinearLayout>
and a res/drawable/border.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<stroke
android:width="5dip"
android:color="@android:color/white" />
</shape>
Reported to work on a gingerbread device. Note that you'll need to relate android:padding
of the LinearLayout to the android:width
shape/stroke's value. Please, do not use @android:color/white
in your final application but rather a project defined color.
You could apply android:background="@drawable/border" android:padding="10dip"
to each of the LinearLayout from your provided sample.
As for your other posts related to display some circles as LinearLayout's background, I'm playing with Inset/Scale/Layer drawable resources (see Drawable Resources for further information) to get something working to display perfect circles in the background of a LinearLayout but failed at the moment…
Your problem resides clearly in the use of getBorder.set{Width,Height}(100);
. Why do you do that in an onClick method?
I need further information to not miss the point: why do you do that programmatically? Do you need a dynamic behavior? Your input drawables are png or ShapeDrawable is acceptable? etc.
To be continued (maybe tomorrow and as soon as you provide more precisions on what you want to achieve)…

I think I remember seeing before that if you are updating to the same value SQL Server will actually recognize this and won't do an unnecessary write.
An int64_t should be 64 bits wide on any platform (hence the name), whereas a long can have different lengths on different platforms. In particular, sizeof(long) is often 4, ie. 32 bits.
You can add days in different formats:
// Normal adding
moment().add(7, 'days');
// Short Hand
moment().add(7, 'd');
// Literal Object
moment().add({days:7, months:1});

The following example show you how to define a function in jQuery. You will see a button “Click here”, when you click on it, we call our function “myFunction()”.
$(document).ready(function(){
$.myFunction = function(){
alert('You have successfully defined the function!');
}
$(".btn").click(function(){
$.myFunction();
});
});
You can see an example here: How to define a function in jQuery?
Your question is a little unclear. If you're generating hostDict
in a loop:
with open('data.txt', 'a') as outfile:
for hostDict in ....:
json.dump(hostDict, outfile)
outfile.write('\n')
If you mean you want each variable within hostDict
to be on a new line:
with open('data.txt', 'a') as outfile:
json.dump(hostDict, outfile, indent=2)
When the indent
keyword argument is set it automatically adds newlines.
There are no multi-dimensional arrays in Java, there are, however, arrays of arrays.
Just make an array of however large you want, then for each element make another array however large you want that one to be.
int array[][];
array = new int[10][];
array[0] = new int[9];
array[1] = new int[8];
array[2] = new int[7];
array[3] = new int[6];
array[4] = new int[5];
array[5] = new int[4];
array[6] = new int[3];
array[7] = new int[2];
array[8] = new int[1];
array[9] = new int[0];
Alternatively:
List<Integer>[] array;
array = new List<Integer>[10];
// of you can do "new ArrayList<Integer>(the desired size);" for all of the following
array[0] = new ArrayList<Integer>();
array[1] = new ArrayList<Integer>();
array[2] = new ArrayList<Integer>();
array[3] = new ArrayList<Integer>();
array[4] = new ArrayList<Integer>();
array[5] = new ArrayList<Integer>();
array[6] = new ArrayList<Integer>();
array[7] = new ArrayList<Integer>();
array[8] = new ArrayList<Integer>();
array[9] = new ArrayList<Integer>();
Why don't you use spring's TransactionTemplate
to programmatically control transactions? You could also restructure your code so that each "transaction block" has it's own @Transactional
method, but given that it's a test I would opt for programmatic control of your transactions.
Also note that the @Transactional
annotation on your runnable won't work (unless you are using aspectj) as the runnables aren't managed by spring!
@RunWith(SpringJUnit4ClassRunner.class)
//other spring-test annotations; as your database context is dirty due to the committed transaction you might want to consider using @DirtiesContext
public class TransactionTemplateTest {
@Autowired
PlatformTransactionManager platformTransactionManager;
TransactionTemplate transactionTemplate;
@Before
public void setUp() throws Exception {
transactionTemplate = new TransactionTemplate(platformTransactionManager);
}
@Test //note that there is no @Transactional configured for the method
public void test() throws InterruptedException {
final Contract c1 = transactionTemplate.execute(new TransactionCallback<Contract>() {
@Override
public Contract doInTransaction(TransactionStatus status) {
Contract c = contractDOD.getNewTransientContract(15);
contractRepository.save(c);
return c;
}
});
ExecutorService executorService = Executors.newFixedThreadPool(5);
for (int i = 0; i < 5; ++i) {
executorService.execute(new Runnable() {
@Override //note that there is no @Transactional configured for the method
public void run() {
transactionTemplate.execute(new TransactionCallback<Object>() {
@Override
public Object doInTransaction(TransactionStatus status) {
// do whatever you want to do with c1
return null;
}
});
}
});
}
executorService.shutdown();
executorService.awaitTermination(10, TimeUnit.SECONDS);
transactionTemplate.execute(new TransactionCallback<Object>() {
@Override
public Object doInTransaction(TransactionStatus status) {
// validate test results in transaction
return null;
}
});
}
}
I use:
body.modal-open .datepicker {
z-index: 1200 !important;
}
This way: if the modal isn't open, and you want the datepicker to be at the normal z-index (in my case I needed it to be under the menu drop-down, which has a z-index of 1000), it works.
If the modal is open, the datepicker needs to be over the modal z-index (1040 or 1050), so use the body.modal-open
selector.

I think this other Stack Overflow answer would solve your problem: How do I run a bat file in the background from another bat file?

Since people will be coming from Google, make sure you're in the right database.
Running SQL in the 'master' database will often return this error.
I want to let everyone know that sometimes this error just is a result of some weird memory error. Restart your pc and go back into visual studio and it will be gone!! Bizarre! Try that before you start playing around with your web config file etc like I did!!!! ;-)
I can think of doing it in two ways:
Storing the file in file system in any directory (say dir1
) and renaming it which ensures that the name is unique for every file (may be a timestamp) (say xyz123.jpg
), and then storing this name in some DataBase. Then while generating the JSON you pull this filename and generate a complete URL (which will be http://example.com/dir1/xyz123.png
)and insert it in the JSON.
Base 64 Encoding, It's basically a way of encoding arbitrary binary data in ASCII text. It takes 4 characters per 3 bytes of data, plus potentially a bit of padding at the end. Essentially each 6 bits of the input is encoded in a 64-character alphabet. The "standard" alphabet uses A-Z, a-z, 0-9 and + and /, with = as a padding character. There are URL-safe variants. So this approach will allow you to put your image directly in the MongoDB, while storing it Encode the image and decode while fetching it, it has some of its own drawbacks:
A.) Canvas
Load the image into an Image-Object, paint it to a canvas and convert the canvas back to a dataURL.
function convertToDataURLviaCanvas(url, callback, outputFormat){
var img = new Image();
img.crossOrigin = 'Anonymous';
img.onload = function(){
var canvas = document.createElement('CANVAS');
var ctx = canvas.getContext('2d');
var dataURL;
canvas.height = this.height;
canvas.width = this.width;
ctx.drawImage(this, 0, 0);
dataURL = canvas.toDataURL(outputFormat);
callback(dataURL);
canvas = null;
};
img.src = url;
}
Usage
convertToDataURLviaCanvas('http://bit.ly/18g0VNp', function(base64Img){
// Base64DataURL
});
Supported input formats
image/png
, image/jpeg
, image/jpg
, image/gif
, image/bmp
, image/tiff
, image/x-icon
, image/svg+xml
, image/webp
, image/xxx
B.) FileReader
Load the image as blob via XMLHttpRequest and use the FileReader API to convert it to a data URL.
function convertFileToBase64viaFileReader(url, callback){
var xhr = new XMLHttpRequest();
xhr.responseType = 'blob';
xhr.onload = function() {
var reader = new FileReader();
reader.onloadend = function () {
callback(reader.result);
}
reader.readAsDataURL(xhr.response);
};
xhr.open('GET', url);
xhr.send();
}
This approach
Usage
convertFileToBase64viaFileReader('http://bit.ly/18g0VNp', function(base64Img){
// Base64DataURL
});
This error is weird as many proposed answers and got mixed solutions. I tried them, add them. It was only when I added pip install --upgrade pip
finally removed the error for me. But I have no time to isolate which is which,so this is just fyi.
models.Post.find({published: true}, {sort: {'date': -1}, limit: 20}, function(err, posts) {

its better to bind a click handler to the entire table and then use event.target to get the clicked TD. Thats all i can add to this as its 1:20am
If you want to use base_url()
, so we need to load url helper.
$autoload['helper'] = array('url');
$this->load->helper('url');
Then you can user base_url()
anywhere in controller or view.
If you have perl installed, then perl -i -n -e"print unless m{(ERROR|REFERENCE)}"
should do the trick.
String.valueOf
(
Character.toChars(int)
)
Assuming the integer is, as you say, between 0 and 255, you'll get an array with a single character back from Character.toChars
, which will become a single-character string when passed to String.valueOf
.
Using Character.toChars
is preferable to methods involving a cast from int
to char
(i.e. (char) i
) for a number of reasons, including that Character.toChars
will throw an IllegalArgumentException
if you fail to properly validate the integer while the cast will swallow the error (per the narrowing primitive conversions specification), potentially giving an output other than what you intended.

Change jQueryUI to version 1.11.4 and make sure jQuery is not added twice.
In arraylist you have a positional order and not a nominal order, so you need to know in advance the element position you need to select or you must loop between elements until you find the element that you need to use. To do this you can use an iterator and an if, for example:
Iterator iter = list.iterator();
while (iter.hasNext())
{
// if here
System.out.println("string " + iter.next());
}
Based on various answers on Stack Overflow and blogs I've come across, this is the method I'm using, and it seems to return real words quite well. The idea is to split the incoming text into an array of words (use whichever method you'd like), and then find the parts of speech (POS) for those words and use that to help stem and lemmatize the words.
You're sample above doesn't work too well, because the POS can't be determined. However, if we use a real sentence, things work much better.
import nltk
from nltk.corpus import wordnet
lmtzr = nltk.WordNetLemmatizer().lemmatize
def get_wordnet_pos(treebank_tag):
if treebank_tag.startswith('J'):
return wordnet.ADJ
elif treebank_tag.startswith('V'):
return wordnet.VERB
elif treebank_tag.startswith('N'):
return wordnet.NOUN
elif treebank_tag.startswith('R'):
return wordnet.ADV
else:
return wordnet.NOUN
def normalize_text(text):
word_pos = nltk.pos_tag(nltk.word_tokenize(text))
lemm_words = [lmtzr(sw[0], get_wordnet_pos(sw[1])) for sw in word_pos]
return [x.lower() for x in lemm_words]
print(normalize_text('cats running ran cactus cactuses cacti community communities'))
# ['cat', 'run', 'ran', 'cactus', 'cactuses', 'cacti', 'community', 'community']
print(normalize_text('The cactus ran to the community to see the cats running around cacti between communities.'))
# ['the', 'cactus', 'run', 'to', 'the', 'community', 'to', 'see', 'the', 'cat', 'run', 'around', 'cactus', 'between', 'community', '.']
I commented out the line with the following setting

Its not really an elegant solution, but it worked for my needs. (Just getting a basic PMA for running queries etc without UI customization).
Please do this only if you do not care about UI Prefs. If not, other people have answered this question very well.
Simply put, this is wrong because it unnecessarily opens up possibilities to MANY bugs. When the @Override
is invoked, the state of the object may be inconsistent and/or incomplete.
A quote from Effective Java 2nd Edition, Item 17: Design and document for inheritance, or else prohibit it:
There are a few more restrictions that a class must obey to allow inheritance. Constructors must not invoke overridable methods, directly or indirectly. If you violate this rule, program failure will result. The superclass constructor runs before the subclass constructor, so the overriding method in the subclass will be invoked before the subclass constructor has run. If the overriding method depends on any initialization performed by the subclass constructor, the method will not behave as expected.
Here's an example to illustrate:
public class ConstructorCallsOverride {
public static void main(String[] args) {
abstract class Base {
Base() {
overrideMe();
}
abstract void overrideMe();
}
class Child extends Base {
final int x;
Child(int x) {
this.x = x;
}
@Override
void overrideMe() {
System.out.println(x);
}
}
new Child(42); // prints "0"
}
}
Here, when Base
constructor calls overrideMe
, Child
has not finished initializing the final int x
, and the method gets the wrong value. This will almost certainly lead to bugs and errors.
Constructors with many parameters can lead to poor readability, and better alternatives exist.
Here's a quote from Effective Java 2nd Edition, Item 2: Consider a builder pattern when faced with many constructor parameters:
Traditionally, programmers have used the telescoping constructor pattern, in which you provide a constructor with only the required parameters, another with a single optional parameters, a third with two optional parameters, and so on...
The telescoping constructor pattern is essentially something like this:
public class Telescope {
final String name;
final int levels;
final boolean isAdjustable;
public Telescope(String name) {
this(name, 5);
}
public Telescope(String name, int levels) {
this(name, levels, false);
}
public Telescope(String name, int levels, boolean isAdjustable) {
this.name = name;
this.levels = levels;
this.isAdjustable = isAdjustable;
}
}
And now you can do any of the following:
new Telescope("X/1999");
new Telescope("X/1999", 13);
new Telescope("X/1999", 13, true);
You can't, however, currently set only the name
and isAdjustable
, and leaving levels
at default. You can provide more constructor overloads, but obviously the number would explode as the number of parameters grow, and you may even have multiple boolean
and int
arguments, which would really make a mess out of things.
As you can see, this isn't a pleasant pattern to write, and even less pleasant to use (What does "true" mean here? What's 13?).
Bloch recommends using a builder pattern, which would allow you to write something like this instead:
Telescope telly = new Telescope.Builder("X/1999").setAdjustable(true).build();
Note that now the parameters are named, and you can set them in any order you want, and you can skip the ones that you want to keep at default values. This is certainly much better than telescoping constructors, especially when there's a huge number of parameters that belong to many of the same types.
On laravel 5.6 it has a very simple solution:
User::where('username', $username)->first()->groupName;
It will return groupName as a string.
Strings are immutable, so actully you can't change the String afterwards (you can only make the variable that held the String object point to a different String object).
However, that is not the reason why you can bind any variable to a final
parameter. All the compiler checks is that the parameter is not reassigned within the method. This is good for documentation purposes, arguably good style, and may even help optimize the byte code for speed (although this seems not to do very much in practice).
But even if you do reassign a parameter within a method, the caller doesn't notice that, because java does all parameter passing by value. After the sequence
a = someObject();
process(a);
the fields of a may have changed, but a is still the same object it was before. In pass-by-reference languages this may not be true.

The onPressed
callback for the buttons in the examples above were empty, but you could add something like this:
Widget launchButton = FlatButton(
child: Text("Launch missile"),
onPressed: () {
Navigator.of(context).pop(); // dismiss dialog
launchMissile();
},
);
If you make the callback null
, then the button will be disabled.

I Had similar issue. Every project has his own gradle folder, check if in your project root there's another gradle folder:
/my_projects_root_folder/project/gradle
/my_projects_root_folder/gradle
If so, in every folder you'll find /gradle/wrapper/gradle-wrapper.properties.
Check if in /my_projects_root_folder/gradle/gradle-wrapper.properties gradle version at least match /my_projects_root_folder/ project/ gradle/ gradle-wrapper.properties gradle version
Or just delete/rename your /my_projects_root_folder/gradle and restart android studio and let Gradle sync work and download required gradle.
