In case you are indeed using the SSH URL, but still are asked for username and password when git pushing:
git remote set-url origin [email protected]:<Username>/<Project>.git
You should try troubleshooting with:
ssh -vT [email protected]
Below is a piece of sample output:
...
debug1: Trying private key: /c/Users/Yuci/.ssh/id_rsa
debug1: Trying private key: /c/Users/Yuci/.ssh/id_dsa
debug1: Trying private key: /c/Users/Yuci/.ssh/id_ecdsa
debug1: Trying private key: /c/Users/Yuci/.ssh/id_ed25519
debug1: No more authentication methods to try.
Permission denied (publickey).
I actually have already added the public key to GitHub before, and I also have the private key locally. However, my private key is of a different name called /c/Users/Yuci/.ssh/github_rsa
.
According to the sample output, Git is trying /c/Users/Yuci/.ssh/id_rsa
, which I don't have. Therefore, I could simply copy github_rsa
to id_rsa
in the same directory.
cp /c/Users/Yuci/.ssh/github_rsa /c/Users/Yuci/.ssh/id_rsa
Now when I run ssh -vT [email protected]
again, I have:
...
debug1: Trying private key: /c/Users/Yuci/.ssh/id_rsa
debug1: Authentication succeeded (publickey).
...
Hi <my username>! You've successfully authenticated, but GitHub does not provide shell access.
...
And now I can push to GitHub without being asked for username and password :-)
If you just want to filter null values out of a stream, you can simply use a method reference to java.util.Objects.nonNull(Object). From its documentation:
This method exists to be used as a Predicate,
filter(Objects::nonNull)
For example:
List<String> list = Arrays.asList( null, "Foo", null, "Bar", null, null);
list.stream()
.filter( Objects::nonNull ) // <-- Filter out null values
.forEach( System.out::println );
This will print:
Foo
Bar
Thanks Jason Rogers's answer first.
In Android && cpp should be this:
const char *nativeString = env->GetStringUTFChars(javaString, nullptr);
// use your string
env->ReleaseStringUTFChars(javaString, nativeString);
Can fix this errors:
1.error: base operand of '->' has non-pointer type 'JNIEnv {aka _JNIEnv}'
2.error: no matching function for call to '_JNIEnv::GetStringUTFChars(JNIEnv*&, _jstring*&, bool)'
3.error: no matching function for call to '_JNIEnv::ReleaseStringUTFChars(JNIEnv*&, _jstring*&, char const*&)'
4.add "env->DeleteLocalRef(nativeString);" at end.
If you really need to do this, use reverse proxy.
For example, with nginx as reverse proxy
server {
listen api.mydomain.com:80;
server_name api.mydomain.com;
location / {
proxy_pass http://127.0.0.1:8000;
}
}
Cast it as an int and subtract
$integer = (int)$your_number;
$decimal = $your_number - $integer;
Or just to get the decimal for comparison
$decimal = $your_number - (int)$your_number
After going down the rabbit-hole of trying to do this myself by copy-pasting various code-snippets from Stack Overflow, I would highly recommend just using the InteractJS library, which allows you to create a draggable and resizable div (somewhat) easily.
This has been solved by flexbox, once and forever:

If you want to write a loop in Python which prints some integer no etc, then just copy and paste this code, it'll work a lot
# Display Value from 1 TO 3
for i in range(1,4):
print "",i,"value of loop"
# Loop for dictionary data type
mydata = {"Fahim":"Pakistan", "Vedon":"China", "Bill":"USA" }
for user, country in mydata.iteritems():
print user, "belongs to " ,country
With Bootstrap 4+, you can simply add the class custom-select
for your select inputs to drop the browser-specific styling and keep the arrow icons.

Here is a simple illustrative example on how double underscore properties can affect an inherited class. So with the following setup:
class parent(object):
__default = "parent"
def __init__(self, name=None):
self.default = name or self.__default
@property
def default(self):
return self.__default
@default.setter
def default(self, value):
self.__default = value
class child(parent):
__default = "child"
if you then create a child instance in the python REPL, you will see the below
child_a = child()
child_a.default # 'parent'
child_a._child__default # 'child'
child_a._parent__default # 'parent'
child_b = child("orphan")
## this will show
child_b.default # 'orphan'
child_a._child__default # 'child'
child_a._parent__default # 'orphan'
This may be obvious to some, but it caught me off guard in a much more complex environment
You need to use df.shift
here.
df.shift(i)
shifts the entire dataframe by i
units down.
So, for i = 1
:
Input:
x1 x2
0 206 214
1 226 234
2 245 253
3 265 272
4 283 291
Output:
x1 x2
0 Nan Nan
1 206 214
2 226 234
3 245 253
4 265 272
So, run this script to get the expected output:
import pandas as pd
df = pd.DataFrame({'x1': ['206', '226', '245',' 265', '283'],
'x2': ['214', '234', '253', '272', '291']})
print(df)
df['x2'] = df['x2'].shift(1)
print(df)

Pushwatch is a free to use online GCM and APNS push notification tester developed by myself in Django/Python as I have found myself in a similar situation while working on multiple projects. It can send both GCM
and APNS
notifications and also support JSON messages for extra arguments. Following are the links to the testers.
Please let me know if you have any questions or face issues using it.
You may still want to use VARCHAR in cases where you don't always store a hash for the user (i.e. authenticating accounts/forgot login url). Once a user has authenticated/changed their login info they shouldn't be able to use the hash and should have no reason to. You could create a separate table to store temporary hash -> user associations that could be deleted but I don't think most people bother to do this.
Containers use the OS kernel. Windows Container utilize processes in order to run. So theoretically speaking Windows Containers cannot run on Linux.
However there are workarounds utilizing VMstyle solutions.
I Have found this solution which uses Vagrant and Packer on Mac, so it should work for Linux as well: https://github.com/StefanScherer/windows-docker-machine
This Vagrant environment creates a Docker Machine to work on your MacBook with Windows containers. You can easily switch between Docker for Mac Linux containers and the Windows containers.
building the headless Vagrant box
$ git clone https://github.com/StefanScherer/packer-windows $ cd packer-windows $ packer build --only=vmware-iso windows_2019_docker.json $ vagrant box add windows_2019_docker windows_2019_docker_vmware.box
Create the Docker Machine
$ git clone https://github.com/StefanScherer/windows-docker-machine $ cd windows-docker-machine $ vagrant up --provider vmware_fusion 2019
Switch to Windows containers
$ eval $(docker-machine env 2019)
I hope following example shed some light on constructor chaining.
my use case here for example, you are expecting user to pass a directory to your
constructor, user doesn't know what directory to pass and decides to let
you assign default directory. you step up and assign a default directory that you think
will work.
BTW, I used LINQPad for this example in case you are wondering what *.Dump() is.

{
CtorChaining ctorNoparam = new CtorChaining();
ctorNoparam.Dump();

You may also want to set the button size.
QPixmap pixmap("image_path");
QIcon ButtonIcon(pixmap);
button->setIcon(ButtonIcon);
button->setIconSize(pixmap.rect().size());
button->setFixedSize(pixmap.rect().size());
If you want to return a char*
from a function, make sure you malloc()
it. Stack initialized character arrays make no sense in returning, as accessing them after returning from that function is undefined behavior.
change it to
char* createStr() {
char char1= 'm';
char char2= 'y';
char *str = malloc(3 * sizeof(char));
if(str == NULL) return NULL;
str[0] = char1;
str[1] = char2;
str[2] = '\0';
return str;
}
My approach with jQuery to just make all of the embedded anchor links slide instead of jump instantly
It's really similar to the answer by Santi Nunez but it's more reliable.
<a href="#myid">Go to</a>
<div id="myid"></div>
// Slow scroll with anchors
(function($){
$(document).on('click', 'a[href^=#]', function(e){
e.preventDefault();
var id = $(this).attr('href');
$('html,body').animate({scrollTop: $(id).offset().top}, 500);
});
})(jQuery);
This means that a TCP RST was received and the connection is now closed. This occurs when a packet is sent from your end of the connection but the other end does not recognize the connection; it will send back a packet with the RST bit set in order to forcibly close the connection.
This can happen if the other side crashes and then comes back up or if it calls close()
on the socket while there is data from you in transit, and is an indication to you that some of the data that you previously sent may not have been received.
It is up to you whether that is an error; if the information you were sending was only for the benefit of the remote client then it may not matter that any final data may have been lost. However you should close the socket and free up any other resources associated with the connection.
DateTime.Today represents the current system date with the time part set to 00:00:00
and
DateTime.Now represents the current system date and time
My experience:
var text = $('#myInputField');
var myObj = {title: 'Some title', content: text};
$.post(myUrl, myObj, callback);
The problem is that I forgot to add .val() to the end of $('#myInputField'); this action makes me waste time trying to figure out what was wrong, causing Illegal Invocation Error, since $('#myInputField') was in a different file than that system pointed out incorrect code. Hope this answer help fellows in the same mistake to avoid to loose time.
Client Side JS function to automatically click a link when...
Here is an example where you check the value of a hidden form input, which holds an error passed down from the server.. your client side JS then checks the value of it and populates an error in another location that you specify..in this case a pop-up login modal.
var signUperror = document.getElementById('handleError')
if (signUperror) {
if(signUperror.innerHTML != ""){
var clicker = function(){
document.getElementById('signup').click()
}
clicker()
}
}
If you don't like anonymous functions:
try {
DB::connection()->pdo->beginTransaction();
// database queries here
DB::connection()->pdo->commit();
} catch (\PDOException $e) {
// Woopsy
DB::connection()->pdo->rollBack();
}
Update: For laravel 4, the pdo
object isn't public anymore so:
try {
DB::beginTransaction();
// database queries here
DB::commit();
} catch (\PDOException $e) {
// Woopsy
DB::rollBack();
}
for my use case, i wanted to grab the SHA1 hash from the magisk config file. the below worked for me.
adb shell "su -c "cat /sbin/.magisk/config | grep SHA | awk -F= '{ print $2 }'""
Well, Chrome is multiprocess, and I think every process deals with its own Javascript code, but as far as the code knows, it is "single-threaded".
There is no support whatsoever in Javascript for multi-threading, at least not explicitly, so it does not make a difference.
map
: It returns a new RDD
by applying a function to each element of the RDD
. Function in .map can return only one item.
flatMap
: Similar to map, it returns a new RDD
by applying a function to each element of the RDD, but the output is flattened.
Also, function in flatMap
can return a list of elements (0 or more)
For Example:
sc.parallelize([3,4,5]).map(lambda x: range(1,x)).collect()
Output: [[1, 2], [1, 2, 3], [1, 2, 3, 4]]
sc.parallelize([3,4,5]).flatMap(lambda x: range(1,x)).collect()
Output: notice o/p is flattened out in a single list [1, 2, 1, 2, 3, 1, 2, 3, 4]

In my case i was missing trailing /

Try layout()
which I have used for this in the past by simply creating an empty plot below, properly scaled at around 1/4 or so and placing the legend parts manually in it.
There are some older questions here about legend()
which should get you started.
My simple think you missed type="text/css"
.
You could explicitly create a DatetimeIndex
when initializing the dataframe. Assuming your data is in string format
data = [
('2015-09-25 00:46', '71.925000'),
('2015-09-25 00:47', '71.625000'),
('2015-09-25 00:48', '71.333333'),
('2015-09-25 00:49', '64.571429'),
('2015-09-25 00:50', '72.285714'),
]
index, values = zip(*data)
frame = pd.DataFrame({
'values': values
}, index=pd.DatetimeIndex(index))
print(frame.index.minute)
First of all, I'd recommend you to go through NumPy's Quickstart tutorial, which will probably help with these basic questions.
You can directly create an array from a list as:
import numpy as np
a = np.array( [2,3,4] )
Or from a from a nested list in the same way:
import numpy as np
a = np.array( [[2,3,4], [3,4,5]] )
l = Location.find(:id => id, :select => "name, website, city", :limit => 1)
...or...
l = Location.find_by_sql(:conditions => ["SELECT name, website, city FROM locations WHERE id = ? LIMIT 1", id])
This reference doc gives you the entire list of options you can use with .find
, including how to limit by number, id, or any other arbitrary column/constraint.
l = Location.where(["id = ?", id]).select("name, website, city").first
Ref: Active Record Query Interface
You can also swap the order of these chained calls, doing .select(...).where(...).first
- all these calls do is construct the SQL query and then send it off.

Updated to show using Match (with .Index) to find a value in a dimension of a two-dimensional array:
Dim arr(1 To 10, 1 To 2)
Dim x
For x = 1 To 10
arr(x, 1) = x
arr(x, 2) = 11 - x
Next x
Debug.Print Application.Match(3, Application.Index(arr, 0, 1), 0)
Debug.Print Application.Match(3, Application.Index(arr, 0, 2), 0)
EDIT: it's worth illustrating here what @ARich pointed out in the comments - that using Index()
to slice an array has horrible performance if you're doing it in a loop.
In testing (code below) the Index() approach is almost 2000-fold slower than using a nested loop.
Sub PerfTest()
Const VAL_TO_FIND As String = "R1800:C8"
Dim a(1 To 2000, 1 To 10)
Dim r As Long, c As Long, t

For c = 1 To 10
a(r, c) = "R" & r & ":C" & c

Next r
t = Timer
Debug.Print FindLoop(a, VAL_TO_FIND), Timer - t
' >> 0.00781 sec

Dim r As Long, c As Long

End If
Next c

Function FindIndex(arr, val)
Dim r As Long
For r = 1 To UBound(arr, 1)
If Not IsError(Application.Match(val, Application.Index(arr, r, 0), 0)) Then
FindIndex = True
Exit Function
End If
Next r
End Function
This is the code I wound up with, based upon the other answers here. This is for an HttpPost that receives and responds with complex types:
Task<HttpResponseMessage> response = httpClient.PostAsJsonAsync(
strMyHttpPostURL,
new MyComplexObject { Param1 = param1, Param2 = param2}).ContinueWith((postTask) => postTask.Result.EnsureSuccessStatusCode());
//debug:
//String s = response.Result.Content.ReadAsStringAsync().Result;
MyOtherComplexType moct = (MyOtherComplexType)JsonConvert.DeserializeObject(response.Result.Content.ReadAsStringAsync().Result, typeof(MyOtherComplexType));
Another Solution in Case You Don't Have Control Over Dynamic Content
This works if you didn't load your element through a directive (ie. like in the example in the commented jsfiddles).
Wrap up Your Content
Wrap your content in a div so that you can select it if you are using JQuery. You an also opt to use native javascript to get your element.
<div class="selector">
<grid-filter columnname="LastNameFirstName" gridname="HomeGrid"></grid-filter>
</div>
Use Angular Injector
You can use the following code to get a reference to $compile if you don't have one.
$(".selector").each(function () {
var content = $(this);
angular.element(document).injector().invoke(function($compile) {
var scope = angular.element(content).scope();
$compile(content)(scope);
});
});
Summary
The original post seemed to assume you had a $compile reference handy. It is obviously easy when you have the reference, but I didn't so this was the answer for me.
One Caveat of the previous code
If you are using a asp.net/mvc bundle with minify scenario you will get in trouble when you deploy in release mode. The trouble comes in the form of Uncaught Error: [$injector:unpr] which is caused by the minifier messing with the angular javascript code.
Here is the way to remedy it:
Replace the prevous code snippet with the following overload.
...
angular.element(document).injector().invoke(
[
"$compile", function($compile) {
var scope = angular.element(content).scope();
$compile(content)(scope);
}
]);
...
This caused a lot of grief for me before I pieced it together.

Then I paused execution and I changed problematic view's background color with the command (replacing
0x7f88a8cc2050
with the memory address of your object of course)...
Obj-C
expr ((UIView *)0x7f88a8cc2050).backgroundColor = [UIColor redColor]
Swift 3.0
expr -l Swift -- import UIKit
expr -l Swift -- unsafeBitCast(0x7f88a8cc2050, to: UIView.self).backgroundColor = UIColor.red
... and the result It was awesome!
Simply amazing! Hope It helps.
Regarding existing answers, note that signal handling is platform dependent. Win32 for example handles far fewer signals than POSIX operating systems; see here. While SIGINT is declared in signals.h on Win32, see the note in the documentation that explains that it will not do what you might expect.
For regular Windows users who are not skilled with computers, it is practically not possible to install and use extensions from outside the Chrome Web Store.
Users of other operating systems (Linux, Mac, Chrome OS) can easily install unpacked extensions (in developer mode).
Windows users can also load an unpacked extension, but they will always see an information bubble with "Disable developer mode extensions" when they start Chrome or open a new incognito window, which is really annoying. The only way for Windows users to use unpacked extensions without such dialogs is to switch to Chrome on the developer channel, by installing https://www.google.com/chrome/browser/index.html?extra=devchannel#eula.
Extensions can be loaded in unpacked mode by following the following steps:
chrome://extensions
(via omnibox or menu -> Tools -> Extensions).If you have a crx
file, then it needs to be extracted first. CRX files are zip files with a different header. Any capable zip program should be able to open it. If you don't have such a program, I recommend 7-zip.
These steps will work for almost every extension, except extensions that rely on their extension ID. If you use the previous method, you will get an extension with a random extension ID. If it is important to preserve the extension ID, then you need to know the public key of your CRX file and insert this in your manifest.json. I have previously given a detailed explanation on how to get and use this key at https://stackoverflow.com/a/21500707.
You should include <string.h>
(or its C++ equivalent, <cstring>
).
The lmplot
function returns a FacetGrid
instance. This object has a method called set
, to which you can pass key=value
pairs and they will be set on each Axes object in the grid.
Secondly, you can set only one side of an Axes limit in matplotlib by passing None
for the value you want to remain as the default.
Putting these together, we have:
g = sns.lmplot('X', 'Y', df, col='Z', sharex=False, sharey=False)
g.set(ylim=(0, None))
This will print out a hexadecimal representation of a pthread_t
, no matter what that actually is:
void fprintPt(FILE *f, pthread_t pt) {
unsigned char *ptc = (unsigned char*)(void*)(&pt);
fprintf(f, "0x");
for (size_t i=0; i<sizeof(pt); i++) {
fprintf(f, "%02x", (unsigned)(ptc[i]));
}
}
To just print a small id for a each pthread_t
something like this could be used (this time using iostreams):
void printPt(std::ostream &strm, pthread_t pt) {
static int nextindex = 0;
static std::map<pthread_t, int> ids;
if (ids.find(pt) == ids.end()) {
ids[pt] = nextindex++;
}
strm << ids[pt];
}
Depending on the platform and the actual representation of pthread_t
it might here be necessary to define an operator<
for pthread_t
, because std::map
needs an ordering on the elements:
bool operator<(const pthread_t &left, const pthread_t &right) {
...
}
I might be missing something in your question here... but from what I can gather, by using the subtract method this should be what you're looking to do:
var timeStr = "00:03:15";
timeStr = timeStr.split(':');
var h = timeStr[1],
m = timeStr[2];
var newTime = moment("01:20:00 06-26-2014")
.subtract({'hours': h, 'minutes': m})
.format('hh:mm');
var str = h + " hours and " + m + " minutes earlier: " + newTime;
console.log(str); // 3 hours and 15 minutes earlier: 10:05
$(document).ready(function(){ _x000D_
var timeStr = "00:03:15";_x000D_
timeStr = timeStr.split(':');_x000D_
_x000D_

_x000D_
var str = h + " hours and " + m + " minutes earlier: " + newTime;_x000D_

If you are using VB as code behind, you have to use bracket "()" instead of square bracket "[]".
Example for VB:
<script type="text/javascript">
var accesslevel = '<%= Session("accesslevel").ToString().ToLower() %>';
</script>
Try to wrap wsdlLocation in wsdlUrls
<wsdlUrls>
<wsdlLocation>http://url</wsdlLocation>
</wsdlUrls>
For larger data sets where sorting may not be desirable, you can also use the following perl script:
./yourscript.ksh | perl -ne 'if (!defined $x{$_}) { print $_; $x{$_} = 1; }'
This basically just remembers every line output so that it doesn't output it again.
It has the advantage over the "sort | uniq
" solution in that there's no sorting required up front.
yes, supposing your variable is in the global namespace:
<button onclick="myVar += 1;alert('myVar now equals ' + myVar)">Increment!!</button>
hi If you are still not able to make column as AUTO_INCREMENT while creating table. As a work around first create table that is:
create table student( sid integer NOT NULL sname varchar(30), PRIMARY KEY (sid) );
and then explicitly try to alter column bu using the following
alter table student alter column sid set GENERATED BY DEFAULT AS IDENTITY
Or
alter table student alter column sid set GENERATED BY DEFAULT AS IDENTITY (start with 100)
Based on fnord's answer, here is a Unity3D version with added ranges :
Code :
// golden angle in radians
static float Phi = Mathf.PI * ( 3f - Mathf.Sqrt( 5f ) );
static float Pi2 = Mathf.PI * 2;
public static Vector3 Point( float radius , int index , int total , float min = 0f, float max = 1f , float angleStartDeg = 0f, float angleRangeDeg = 360 )
{
// y goes from min (-) to max (+)
var y = ( ( index / ( total - 1f ) ) * ( max - min ) + min ) * 2f - 1f;
// golden angle increment
var theta = Phi * index ;
if( angleStartDeg != 0 || angleRangeDeg != 360 )
{
theta = ( theta % ( Pi2 ) ) ;
theta = theta < 0 ? theta + Pi2 : theta ;
var a1 = angleStartDeg * Mathf.Deg2Rad;
var a2 = angleRangeDeg * Mathf.Deg2Rad;
theta = theta * a2 / Pi2 + a1;
}
// https://stackoverflow.com/a/26127012/2496170
// radius at y
var rY = Mathf.Sqrt( 1 - y * y );
var x = Mathf.Cos( theta ) * rY;
var z = Mathf.Sin( theta ) * rY;
return new Vector3( x, y, z ) * radius;
}

Preview:
An API defines the interfaces by which one piece of software communicates with another at the source level. It provides abstraction by providing a standard set of interfaces - usually functions - that one piece of software (typically a higher-level piece) can invoke from another piece of software (usually a lower-level piece).
For example, an API might abstract the concept of drawing text on the screen through a family of functions that provide everything needed to draw the text. The API merely defines the interface; the piece of software that actually provides the API is known as the implementation of the API.
It is common to call an API a "contract". This is not correct, at least in the legal sense of the term, as an API is not a two-way agreement. The API user (generally, the higher-level software) has zero input into the API and its implementation. It may use the API as-is, or not use it at all: take it or leave it!
A real-world example of an API is the interfaces defined by the C standard and implemented by the standard C library. This API defines a family of basic and essential functions, such as memory management and string manipulation routines.
the easiest way is using command line. Just type in directory of your .xsd file:
xjc myFile.xsd.
So, the java will generate all Pojos.

I understand the original post is for Oracle 10 but this is for reference by anyone else who finds it via Google.
Under Oracle 12c, I found that that my registry$history is empty. This works instead:
select * from registry$sqlpatch;
Try trimming the string to make sure there is no extra white space:
Cursor c = db.rawQuery("SELECT * FROM tbl1 WHERE TRIM(name) = '"+name.trim()+"'", null);
Also use c.moveToFirst()
like @thinksteep mentioned.
This is a complete code for select statements.
SQLiteDatabase db = this.getReadableDatabase();
Cursor c = db.rawQuery("SELECT column1,column2,column3 FROM table ", null);
if (c.moveToFirst()){
do {
// Passing values
String column1 = c.getString(0);
String column2 = c.getString(1);
String column3 = c.getString(2);
// Do something Here with values
} while(c.moveToNext());
}
c.close();
db.close();
The literal answer is:
return (value == 1 ? Periods.VariablePeriods : Periods.FixedPeriods);
Note that the inline if statement, just like an if statement, only checks for true or false. If (value == 1) evaluates to false, it might not necessarily mean that value == 2. Therefore it would be safer like this:
return (value == 1
? Periods.VariablePeriods
: (value == 2
? Periods.FixedPeriods
: Periods.Unknown));
If you add more values an inline if will become unreadable and a switch would be preferred:
switch (value)
{
case 1:
return Periods.VariablePeriods;
case 2:
return Periods.FixedPeriods;
}
The good thing about enums is that they have a value, so you can use the values for the mapping, as user854301 suggested. This way you can prevent unnecessary branches thus making the code more readable and extensible.
For python2 you can also do this
'%(author)s in %(publication)s'%{'author':unicode(self.author),
'publication':unicode(self.publication)}
which is handy if you have a lot of arguments to substitute (particularly if you are doing internationalisation)
Python2.6 onwards supports .format()
'{author} in {publication}'.format(author=self.author,
publication=self.publication)
You can try
$('#id1 p').each(function() {
var text = $(this).text();
$(this).text(text.replace('dog', 'doll'));
});
You could use instead .html()
and/or further sophisticate the .replace()
call according to your needs
We can delete a key from a Python dictionary by the some of the following approaches.
Using the del
keyword; it's almost the same approach like you did though -
myDict = {'one': 100, 'two': 200, 'three': 300 }
print(myDict) # {'one': 100, 'two': 200, 'three': 300}
if myDict.get('one') : del myDict['one']
print(myDict) # {'two': 200, 'three': 300}
Or
We can do like the following:
But one should keep in mind that, in this process actually it won't delete any key from the dictionary rather than making a specific key excluded from that dictionary. In addition, I observed that it returned a dictionary which was not ordered the same as myDict
.
myDict = {'one': 100, 'two': 200, 'three': 300, 'four': 400, 'five': 500}
{key:value for key, value in myDict.items() if key != 'one'}
If we run it in the shell, it'll execute something like {'five': 500, 'four': 400, 'three': 300, 'two': 200}
- notice that it's not the same ordered as myDict
. Again if we try to print myDict
, then we can see all keys including which we excluded from the dictionary by this approach. However, we can make a new dictionary by assigning the following statement into a variable:
var = {key:value for key, value in myDict.items() if key != 'one'}
Now if we try to print it, then it'll follow the parent order:
print(var) # {'two': 200, 'three': 300, 'four': 400, 'five': 500}
Or
Using the pop()
method.
myDict = {'one': 100, 'two': 200, 'three': 300}
print(myDict)
if myDict.get('one') : myDict.pop('one')
print(myDict) # {'two': 200, 'three': 300}
The difference between del
and pop
is that, using pop()
method, we can actually store the key's value if needed, like the following:
myDict = {'one': 100, 'two': 200, 'three': 300}
if myDict.get('one') : var = myDict.pop('one')
print(myDict) # {'two': 200, 'three': 300}
print(var) # 100

I would just go for one of them. It will come with JPA 2.1 anyway and should not be too hard to change in the case that you really want to switch your JPA provider.
Why not iteratively divide by 2?
count = 0 while n > 0 if (n % 2) == 1 count += 1 n /= 2
I agree that this isn't the fastest, but "best" is somewhat ambiguous. I'd argue though that "best" should have an element of clarity
You can set content view (or design) of an activity. For example you can do it like this too :
public void onCreate(Bundle savedinstanceState) {
super.onCreate(savedinstanceState);
Button testButon = new Button(this);
setContentView(testButon);
}

Along the lines of Tim Down's answer but leveraging jQuery
(mentioned by the OP) and loosely coupling the containing page and the iframe, you could do the following:
In the iframe:
<script>
$(function() {
var w = window;
if (w.frameElement != null
&& w.frameElement.nodeName === "IFRAME"
&& w.parent.jQuery) {
w.parent.jQuery(w.parent.document).trigger('iframeready');
}
});
</script>
In the containing page:
<script>
function myHandler() {
alert('iframe (almost) loaded');
}
$(document).on('iframeready', myHandler);
</script>
The iframe fires an event on the (potentially existing) parent window's document - please beware that the parent document needs a jQuery instance of itself for this to work. Then, in the parent window you attach a handler to react to that event.
This solution has the advantage of not breaking when the containing page does not contain the expected load handler. More generally speaking, it shouldn't be the concern of the iframe to know its surrounding environment.
Please note, that we're leveraging the DOM ready event to fire the event - which should be suitable for most use cases. If it's not, simply attach the event trigger line to the window's load event like so:
$(window).on('load', function() { ... });
You can use map
:
List<String> names =
personList.stream()
.map(Person::getName)
.collect(Collectors.toList());
EDIT :
In order to combine the Lists of friend names, you need to use flatMap
:
List<String> friendNames =
personList.stream()
.flatMap(e->e.getFriends().stream())
.collect(Collectors.toList());
This should work:
if (!string.IsNullOrWhiteSpace(dateTimeEnd))
eventCustom.DateTimeEnd = DateTime.Parse(dateTimeEnd);
else
eventCustom.DateTimeEnd = null;
Note that this will throw an exception if the string is not in the correct format.
Use ampersand to specify the parent selector.
SCSS syntax:
p {
margin: 2em auto;
> a {
color: red;
}
&:before {
content: "";
}
&:after {
content: "* * *";
}
}
This will list only modified files:
svn status -u | grep M
You can use relative path to mount the volume to container:
docker run -v `pwd`/certs:/container/path/to/certs ...
Note the back tick on the pwd
which give you the present working directory. It assumes you have the certs
folder in current directory that the docker run
is executed. Kinda great for local development and keep the certs folder visible to your project.
The slightly modified version of COPY
below worked better for me, where I specify the CSV
format. This format treats backslash characters in text without any fuss. The default format is the somewhat quirky TEXT
.
COPY myTable FROM '/path/to/file/on/server' ( FORMAT CSV, DELIMITER('|') );
By default the field delimiter is non-blank to blank transition so tab should work just fine.
However, the columns are indexed base 1 and base 0 so you probably want
sort -k4nr file.txt
to sort file.txt by column 4 numerically in reverse order. (Though the data in the question has even 5 fields so the last field would be index 5.)
you can also use gcc -v
command that works like gcc --version
and if you would like to now where gcc
is you can use whereis gcc
command
I hope it'll be usefull
Use escape characters for example this code:
var message = "I want to learn \"c#\"";
Console.WriteLine(message);
will output:
I want to learn "c#"
It worked for me after I set up a user with internet access in the Windows service.
In my code:
HttpClientHandler handler = new HttpClientHandler();
handler.Proxy = System.Net.WebRequest.DefaultWebProxy;
handler.Proxy.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;
.....
HttpClient httpClient = new HttpClient(handler)
....
Think about what you need to do if you wish to implement:
The order is WHERE, GROUP BY and HAVING.
Depending on the libc release it could be needed to set both SO_REUSEADDR and SO_REUSEPORT socket options as explained in socket(7) documentation :
SO_REUSEPORT (since Linux 3.9) Permits multiple AF_INET or AF_INET6 sockets to be bound to an identical socket address. This option must be set on each socket (including the first socket) prior to calling bind(2) on the socket. To prevent port hijacking, all of the processes binding to the same address must have the same effective UID. This option can be employed with both TCP and UDP sockets.
As this socket option appears with kernel 3.9 and raspberry use 3.12.x, it will be needed to set SO_REUSEPORT.
You can set theses two options before calling bind like this :
int reuse = 1;
if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, (const char*)&reuse, sizeof(reuse)) < 0)
perror("setsockopt(SO_REUSEADDR) failed");
#ifdef SO_REUSEPORT
if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEPORT, (const char*)&reuse, sizeof(reuse)) < 0)
perror("setsockopt(SO_REUSEPORT) failed");
#endif
So how can I question a variable that is a NoneType?
Use is
operator, like this
if variable is None:
Why this works?
Since None
is the sole singleton object of NoneType
in Python, we can use is
operator to check if a variable has None
in it or not.
Quoting from is
docs,
The operators
is
andis not
test for object identity:x is y
is true if and only ifx
andy
are the same object.x is not y
yields the inverse truth value.
Since there can be only one instance of None
, is
would be the preferred way to check None
.
Hear it from the horse's mouth
Quoting Python's Coding Style Guidelines - PEP-008 (jointly defined by Guido himself),
Comparisons to singletons like
None
should always be done withis
oris not
, never the equality operators.
Your problem is with this line:
number4 = list(cow[n])
It tries to take cow[n]
, which returns an integer, and make it a list. This doesn't work, as demonstrated below:
>>> a = 1
>>> list(a)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'int' object is not iterable
>>>
Perhaps you meant to put cow[n]
inside a list:
number4 = [cow[n]]
See a demonstration below:
>>> a = 1
>>> [a]
[1]
>>>
Also, I wanted to address two things:
:
at the end.input
like that, since it evaluates its input as real Python code. It would be better here to use raw_input
and then convert the input to an integer with int
.To split up the digits and then add them like you want, I would first make the number a string. Then, since strings are iterable, you can use sum
:
>>> a = 137
>>> a = str(a)
>>> # This way is more common and preferred
>>> sum(int(x) for x in a)
11
>>> # But this also works
>>> sum(map(int, a))
11
>>>
From the moment.js docs: format('E')
stands for day of week. thus your diff is being computed on which day of the week, which has to be between 1 and 7.
From the moment.js docs again, here is what they suggest:
var a = moment([2007, 0, 29]);
var b = moment([2007, 0, 28]);
a.diff(b, 'days') // 1
Here is a JSFiddle for your particular case:
$('#test').click(function() {_x000D_
var startDate = moment("13.04.2016", "DD.MM.YYYY");_x000D_
var endDate = moment("28.04.2016", "DD.MM.YYYY");_x000D_
_x000D_
var result = 'Diff: ' + endDate.diff(startDate, 'days');_x000D_
_x000D_
$('#result').html(result);_x000D_
});

On unixoid systems (and in php 7+ on Windows as well), you can use getrusage, like:
// Script start
$rustart = getrusage();
// Code ...
// Script end
function rutime($ru, $rus, $index) {
return ($ru["ru_$index.tv_sec"]*1000 + intval($ru["ru_$index.tv_usec"]/1000))
- ($rus["ru_$index.tv_sec"]*1000 + intval($rus["ru_$index.tv_usec"]/1000));
}
$ru = getrusage();
echo "This process used " . rutime($ru, $rustart, "utime") .
" ms for its computations\n";
echo "It spent " . rutime($ru, $rustart, "stime") .
" ms in system calls\n";
Note that you don't need to calculate a difference if you are spawning a php instance for every test.

For i = 1 To col.Count
If col.item(i) = item Then
Contains = True
Exit Function
End If
Next i
Contains = False
End Function

I usually set up my DB's to have one table that contains all the keys and the modified dates and such. Haven't run into a problem of duplicate keys ever.
The only drawback that it has is when you are writing some queries to find some information quickly you are doing a lot of copying and pasting of the keys. You don't have the short easy to remember ids anymore.
Use a linked list. It was designed for this exact situation.
If you still need the dictionary O(1) lookups, use both a dictionary and a linked list.

My understanding is that C++ allows static const members to be defined inside a class so long as it's an integer type.
You are sort of correct. You are allowed to initialize static const integrals in the class declaration but that is not a definition.
Interestingly, if I comment out the call to std::min, the code compiles and links just fine (even though test::N is also referenced on the previous line).
Any idea as to what's going on?
std::min takes its parameters by const reference. If it took them by value you'd not have this problem but since you need a reference you also need a definition.
Here's chapter/verse:
9.4.2/4 - If a static
data member is of const
integral or const
enumeration type, its declaration in the class definition can specify a constant-initializer which shall be an integral constant expression (5.19). In that case, the member can appear in integral constant expressions. The member shall still be defined in a namespace scope if it is used in the program and the namespace scope definition shall not contain an initializer.
See Chu's answer for a possible workaround.

The traditional for loop in Objective-C is inherited from standard C and takes the following form:
for (/* Instantiate local variables*/ ; /* Condition to keep looping. */ ; /* End of loop expressions */)
{
// Do something.
}
For example, to print the numbers from 1 to 10, you could use the for loop:
for (int i = 1; i <= 10; i++)
{
NSLog(@"%d", i);
}
On the other hand, the for in loop was introduced in Objective-C 2.0, and is used to loop through objects in a collection, such as an NSArray instance. For example, to loop through a collection of NSString objects in an NSArray and print them all out, you could use the following format.
for (NSString* currentString in myArrayOfStrings)
{
NSLog(@"%@", currentString);
}
This is logically equivilant to the following traditional for loop:
for (int i = 0; i < [myArrayOfStrings count]; i++)
{
NSLog(@"%@", [myArrayOfStrings objectAtIndex:i]);
}
The advantage of using the for in loop is firstly that it's a lot cleaner code to look at. Secondly, the Objective-C compiler can optimize the for in loop so as the code runs faster than doing the same thing with a traditional for loop.
Hope this helps.
In order to get last N records you can execute below query:
db.yourcollectionname.find({$query: {}, $orderby: {$natural : -1}}).limit(yournumber)
if you want only one last record:
db.yourcollectionname.findOne({$query: {}, $orderby: {$natural : -1}})
Note: In place of $natural
you can use one of the columns from your collection.
Work for arrays and lists only, not for set.

"This is an example function I'd like to check arguments of"

#dostuff
if 0 < b < 10:
#dostuff
if type( C ) == str and c != "":
#dostuff
java code
public void bubbleSort(int[] arr){
boolean isSwapped = true;
for(int i = arr.length - 1; isSwapped; i--){
isSwapped = false;
for(int j = 0; j < i; j++){
if(arr[j] > arr[j+1]}{
int temp = arr[j];
arr[j] = arr[j+1];
arr[j+1] = temp;
isSwapped = true;
}
}
}
}
Right, there is no way to remove this 'no file choosen', even if you have a list of pre-upload files.
Simplest solution I've found (and works on IE, FF, CR) is the following
$('.addfiles').on('click', function() { $('#fileupload').click();return false;});
_x000D_
<button class="addfiles">Add Files</button>_x000D_
<input id="fileupload" type="file" name="files[]" multiple style='display: none;'>
_x000D_
It's done, works perfectly :)

From the documentation:
With one argument, return the natural logarithm of x (to base e).
With two arguments, return the logarithm of x to the given base, calculated as
log(x)/log(base)
.
But the log10 is made available as math.log10()
, which does not resort to log division if possible.
The answer given by Francois results in listing all the cities from a country. But if the requirement is to list all the regions (cities + states + other regions etc) in a country or the establishments in the country, you can filter results accordingly by changing types.
List only cities in the country
var options = {
types: ['(cities)'],
componentRestrictions: {country: "us"}
};
List all cities, states and regions in the country
var options = {
types: ['(regions)'],
componentRestrictions: {country: "us"}
};
List all establishments — such as restaurants, stores, and offices in the country
var options = {
types: ['establishment'],
componentRestrictions: {country: "us"}
};

armhf
stands for "arm hard float", and is the name given to a debian port for arm processors (armv7+) that have hardware floating point support.
On the beaglebone black, for example:
:~$ dpkg --print-architecture
armhf
Although other commands (such as uname -a
or arch
) will just show armv7l
:~$ cat /proc/cpuinfo
processor : 0
model name : ARMv7 Processor rev 2 (v7l)
BogoMIPS : 995.32
Features : half thumb fastmult vfp edsp thumbee neon vfpv3 tls
...
The vfpv3
listed under Features
is what refers to the floating point support.
Incidentally, armhf
, if your processor supports it, basically supersedes Raspbian, which if I understand correctly was mainly a rebuild of armhf
with work arounds to deal with the lack of floating point support on the original raspberry pi's. Nowdays, of course, there's a whole ecosystem build up around Raspbian, so they're probably not going to abandon it. However, this is partly why the beaglebone runs straight debian, and that's ok even if you're used to Raspbian, unless you want some of the special included non-free software such as Mathematica.
1- The first way is define an interface
public interface OnMessage{
void sendMessage(int fragmentId, String message);
}
public interface OnReceive{
void onReceive(String message);
}
2- In you activity implement OnMessage interface
public class MyActivity implements OnMessage {
...
@Override
public void sendMessage(int fragmentId, String message){
Fragment fragment = getSupportFragmentManager().findFragmentById(fragmentId);
((OnReceive) fragment).sendMessage();
}
}
3- In your fragment implement OnReceive interface
public class MyFragment implements OnReceive{
...
@Override
public void onReceive(String message){
myTextView.setText("Received message:" + message);
}
}
This is the boilerplate version of handling message passing between fragments.
Another way of handing data passage between fragments are by using an event bus.
1- Register/unregister to an event bus
@Override
public void onStart() {
super.onStart();
EventBus.getDefault().register(this);
}
@Override
public void onStop() {
EventBus.getDefault().unregister(this);
super.onStop();
}
2- Define an event class
public class Message{
public final String message;
public Message(String message){
this.message = message;
}
}
3- Post this event in anywhere in your application
EventBus.getDefault().post(new Message("hello world"));
4- Subscribe to that event to receive it in your Fragment
@Subscribe(threadMode = ThreadMode.MAIN)
public void onMessage(Message event){
mytextview.setText(event.message);
}
For more details, use cases, and an example project about the event bus pattern.

Use case: i am using a self-signed certificate for my development on localhost.
Error: Caused by: java.security.cert.CertificateException: No name matching localhost found
Solution: When you generate your self-signed certicate, make sure you answer this question like that(See Bruno's answer for the why):
What is your first and last name?
[Unknown]: localhost
As a bonus, here are my steps:
1. Generate self-signed certificate:
keytool -genkeypair -alias netty -storetype PKCS12 -keyalg RSA -keysize 2048 -keystore keystore.p12 -validity 4000
Enter keystore password: ***
Re-enter new password: ***
What is your first and last name?
[Unknown]: localhost
...
2. Copy the certificate in src/main/resources(if necessary)
3. Update the cacerts
keytool -v -importkeystore -srckeystore keystore.p12 -srcstoretype pkcs12 -destkeystore "%JAVA_HOME%\jre\lib\security\cacerts" -deststoretype jks
4. Update your config(in my case application.properties):
server.port=8443
server.ssl.key-store=classpath:keystore.p12
server.ssl.key-store-password=jumping_monkey
server.ssl.key-store-type=pkcs12
server.ssl.key-alias=netty

It's not possible.
And yes, I think MS made a mistake here.
Their decision does not make sense and forces programmers to write (as described above) a pointless wrapper class.
Here is a good example: Trying to extend static MS Unit testing class Assert: I want 1 more Assert method AreEqual(x1,x2)
.
The only way to do this is to point to different classes or write a wrapper around 100s of different Assert methods. Why!?
If the decision was being made to allow extensions of instances, I see no logical reason to not allow static extensions. The arguments about sectioning libraries does not stand up once instances can be extended.
Actaully there's a hacky solution for this problem. Let's say you want to select the biggest tree of each forest in a region.
SELECT (array_agg(tree.id ORDER BY tree_size.size)))[1]
FROM tree JOIN forest ON (tree.forest = forest.id)
GROUP BY forest.id
When you group trees by forests there will be an unsorted list of trees and you need to find the biggest one. First thing you should do is to sort the rows by their sizes and select the first one of your list. It may seems inefficient but if you have millions of rows it will be quite faster than the solutions that includes JOIN
's and WHERE
conditions.
BTW, note that ORDER_BY
for array_agg
is introduced in Postgresql 9.0

Generally speaking:
all
and any
are functions that take some iterable and return True
, if
all()
, no values in the iterable are falsy;any()
, at least one value is truthy.A value x
is falsy iff bool(x) == False
.
A value x
is truthy iff bool(x) == True
.
Any non-booleans in the iterable will be fine — bool(x)
will coerce any x
according to these rules: 0
, 0.0
, None
, []
, ()
, []
, set()
, and other empty collections will yield False
, anything else True
. The docstring for bool
uses the terms 'true'/'false' for 'truthy'/'falsy', and True
/False
for the concrete boolean values.
In your specific code samples:
You misunderstood a little bit how these functions work. Hence, the following does something completely not what you thought:
if any(foobars) == big_foobar:
...because any(foobars)
would first be evaluated to either True
or False
, and then that boolean value would be compared to big_foobar
, which generally always gives you False
(unless big_foobar
coincidentally happened to be the same boolean value).
Note: the iterable can be a list, but it can also be a generator/generator expression (˜ lazily evaluated/generated list) or any other iterator.
What you want instead is:
if any(x == big_foobar for x in foobars):
which basically first constructs an iterable that yields a sequence of booleans—for each item in foobars
, it compares the item to big_foobar
and emits the resulting boolean into the resulting sequence:
tmp = (x == big_foobar for x in foobars)
then any
walks over all items in tmp
and returns True
as soon as it finds the first truthy element. It's as if you did the following:
In [1]: foobars = ['big', 'small', 'medium', 'nice', 'ugly']
In [2]: big_foobar = 'big'
In [3]: any(['big' == big_foobar, 'small' == big_foobar, 'medium' == big_foobar, 'nice' == big_foobar, 'ugly' == big_foobar])
Out[3]: True
Note: As DSM pointed out, any(x == y for x in xs)
is equivalent to y in xs
but the latter is more readable, quicker to write and runs faster.
Some examples:
In [1]: any(x > 5 for x in range(4))
Out[1]: False
In [2]: all(isinstance(x, int) for x in range(10))
Out[2]: True
In [3]: any(x == 'Erik' for x in ['Erik', 'John', 'Jane', 'Jim'])
Out[3]: True
In [4]: all([True, True, True, False, True])
Out[4]: False

Unfortunately there is only the function setColumnWidth(int columnIndex,
int width) from class Sheet
; in which width is a number of characters in the standard font (first font in the workbook) if your fonts are changing you cannot use it.
There is explained how to calculate the width in function of a font size. The formula is:
width = Truncate([{NumOfVisibleChar} * {MaxDigitWidth} + {5PixelPadding}] / {MaxDigitWidth}*256) / 256
You can always use autoSizeColumn(int column, boolean useMergedCells)
after inputting the data in your Sheet
.
The following should do the trick:
div[class^='myclass'], div[class*=' myclass']{

I wonder why no one have mentioned this simple pattern? :

next()
}(function() {

}))
Using timeouts just for blindly waiting is bad practice; and involving promises just adds more complexity to the code. In OP's case:
(function(next) {
for(i=0;i<x;i++){
// do something
if (i==x-1) next()
}
}(function() {
// now wait for firstFunction to finish...
// do something else
}))

There are Registry changes you can make to explicitly select where the crash dump file resides, otherwise %localappdata%\Microsoft\Windows\WER is the default location. I assume that %localappdata% is defined differently for a user or a service running under System. You will need to enable WER I believe.
Assuming you also want to strip whitespace at beginning and end of each line, you can map the string strip function to the list returned by readlines:
map(str.strip, open('filename').readlines())

QUICK DEPENDENCY MANAGEMENT TUTORIAL, FOLKS
Requirements files allow you to create a snapshot of all packages that have been installed through pip. By encapsulating those packages in a virtualenvironment, you can have your codebase work off a very specific set of packages and share that codebase with others.
From Heroku's documentation https://devcenter.heroku.com/articles/python
You create a virtual environment, and set your shell to use it. (bash/*nix instructions)
virtualenv env
source env/bin/activate
Now all python scripts run with this shell will use this environment's packages and configuration. Now you can install a package locally to this environment without needing to install it globally on your machine.
pip install flask
Now you can dump the info about which packages are installed with
pip freeze > requirements.txt
If you checked that file into version control, when someone else gets your code, they can setup their own virtual environment and install all the dependencies with:
pip install -r requirements.txt
Any time you can automate tedium like this is awesome.
I have resolved below steps.
(1) installed Respond.js module for drupal 7.
(2) lessphp module for drupal 7 set in libraries, instead of module folder.

You cannot change the default but there is a codeless workaround.
Select the whole sheet and change the font size on your data to something small, like 10 or 12. When you zoom in to view the data you will find that the drop down box entries are now visible.
To emphasize, the issue is not so much with the size of the font in the drop down, it is the relative size between drop down and data display font sizes.
Not only does std::vector make a copy of whatever you're pushing back, but the definition of the collection states that it will do so, and that you may not use objects without the correct copy semantics within a vector. So, for example, you do not use auto_ptr in a vector.
I know this is late but it might be of some use:
echo "<pre>";
print_r($array);
echo "</pre>";
You can delay your code using setTimeout
to execute after click
function changeLink(){
setTimeout(function() {
var link = document.getElementById("mylink");
link.setAttribute('href', "http://facebook.com");
document.getElementById("mylink").innerHTML = "facebook";
}, 100);
}
echo '<table><tr><th>Title</th><th>Price</th><th>Number</th></tr>';
foreach($shop as $id => $item) {
echo '<tr><td>'.$item[0].'</td><td>'.$item[1].'</td><td>'.$item[2].'</td></tr>';
}
echo '</table>';
window.history.pushState({urlPath:'/page1'},"",'/page1')
Only works after page is loaded, and when you will click on refresh it doesn't mean that there is any real URL.
What you should do here is knowing to which URL you are getting redirected when you reload this page. And on that page you can get the conditions by getting the current URL and making all of your conditions.

The excellent book "Algorithm Design Manual" by Skienna contains a huge repository of Algorithms and Data structure.
For tons of problems, data structures and algorithm are described, compared, and discusses the practical usage. The author also provides references to implementations and the original research papers.
The book is great to have it on your desk if you search the best data structure for your problem to solve. It is also very helpful for interview preparation.
Another great resource is the NIST Dictionary of Data structures and algorithms.
from itertools import chain, repeat
prompts = chain(["Enter a number: "], repeat("Not a number! Try again: "))
replies = map(input, prompts)
valid_response = next(filter(str.isdigit, replies))
print(valid_response)
Enter a number: a
Not a number! Try again: b
Not a number! Try again: 1
1
or if you want to have a "bad input" message separated from an input prompt as in other answers:
prompt_msg = "Enter a number: "
bad_input_msg = "Sorry, I didn't understand that."
prompts = chain([prompt_msg], repeat('\n'.join([bad_input_msg, prompt_msg])))
replies = map(input, prompts)
valid_response = next(filter(str.isdigit, replies))
print(valid_response)
Enter a number: a
Sorry, I didn't understand that.
Enter a number: b
Sorry, I didn't understand that.
Enter a number: 1
1
prompts = chain(["Enter a number: "], repeat("Not a number! Try again: "))
This combination of itertools.chain
and itertools.repeat
will create an iterator
which will yield strings "Enter a number: "
once, and "Not a number! Try again: "
an infinite number of times:
for prompt in prompts:
print(prompt)
Enter a number:
Not a number! Try again:
Not a number! Try again:
Not a number! Try again:
# ... and so on
replies = map(input, prompts)
- here map
will apply all the prompts
strings from the previous step to the input
function. E.g.:
for reply in replies:
print(reply)
Enter a number: a
a
Not a number! Try again: 1
1
Not a number! Try again: it doesn't care now
it doesn't care now
# and so on...
filter
and str.isdigit
to filter out those strings that contain only digits:
only_digits = filter(str.isdigit, replies)
for reply in only_digits:
print(reply)
Enter a number: a
Not a number! Try again: 1
1
Not a number! Try again: 2
2
Not a number! Try again: b
Not a number! Try again: # and so on...
And to get only the first digits-only string we use next
.String methods: Of course you can use other string methods like str.isalpha
to get only alphabetic strings, or str.isupper
to get only uppercase. See docs for the full list.
Membership testing:
There are several different ways to perform it. One of them is by using __contains__
method:
from itertools import chain, repeat
fruits = {'apple', 'orange', 'peach'}
prompts = chain(["Enter a fruit: "], repeat("I don't know this one! Try again: "))
replies = map(input, prompts)
valid_response = next(filter(fruits.__contains__, replies))
print(valid_response)
Enter a fruit: 1
I don't know this one! Try again: foo
I don't know this one! Try again: apple
apple
Numbers comparison:
There are useful comparison methods which we can use here. For example, for __lt__
(<
):
from itertools import chain, repeat
prompts = chain(["Enter a positive number:"], repeat("I need a positive number! Try again:"))
replies = map(input, prompts)
numeric_strings = filter(str.isnumeric, replies)
numbers = map(float, numeric_strings)
is_positive = (0.).__lt__
valid_response = next(filter(is_positive, numbers))
print(valid_response)
Enter a positive number: a
I need a positive number! Try again: -5
I need a positive number! Try again: 0
I need a positive number! Try again: 5
5.0
Or, if you don't like using dunder methods (dunder = double-underscore), you can always define your own function, or use the ones from the operator
module.
Path existance:
Here one can use pathlib
library and its Path.exists
method:
from itertools import chain, repeat
from pathlib import Path
prompts = chain(["Enter a path: "], repeat("This path doesn't exist! Try again: "))
replies = map(input, prompts)
paths = map(Path, replies)
valid_response = next(filter(Path.exists, paths))
print(valid_response)
Enter a path: a b c
This path doesn't exist! Try again: 1
This path doesn't exist! Try again: existing_file.txt
existing_file.txt
If you don't want to torture a user by asking him something an infinite number of times, you can specify a limit in a call of itertools.repeat
. This can be combined with providing a default value to the next
function:
from itertools import chain, repeat
prompts = chain(["Enter a number:"], repeat("Not a number! Try again:", 2))
replies = map(input, prompts)
valid_response = next(filter(str.isdigit, replies), None)
print("You've failed miserably!" if valid_response is None else 'Well done!')
Enter a number: a
Not a number! Try again: b
Not a number! Try again: c
You've failed miserably!
Sometimes we don't want to reject an input if the user accidentally supplied it IN CAPS or with a space in the beginning or an end of the string. To take these simple mistakes into account we can preprocess the input data by applying str.lower
and str.strip
methods. For example, for the case of membership testing the code will look like this:
from itertools import chain, repeat
fruits = {'apple', 'orange', 'peach'}
prompts = chain(["Enter a fruit: "], repeat("I don't know this one! Try again: "))
replies = map(input, prompts)
lowercased_replies = map(str.lower, replies)
stripped_replies = map(str.strip, lowercased_replies)
valid_response = next(filter(fruits.__contains__, stripped_replies))
print(valid_response)
Enter a fruit: duck
I don't know this one! Try again: Orange
orange
In the case when you have many functions to use for preprocessing, it might be easier to use a function performing a function composition. For example, using the one from here:
from itertools import chain, repeat
from lz.functional import compose
fruits = {'apple', 'orange', 'peach'}
prompts = chain(["Enter a fruit: "], repeat("I don't know this one! Try again: "))
replies = map(input, prompts)
process = compose(str.strip, str.lower) # you can add more functions here
processed_replies = map(process, replies)
valid_response = next(filter(fruits.__contains__, processed_replies))
print(valid_response)
Enter a fruit: potato
I don't know this one! Try again: PEACH
peach
For a simple case, for example, when the program asks for age between 1 and 120, one can just add another filter
:
from itertools import chain, repeat
prompt_msg = "Enter your age (1-120): "
bad_input_msg = "Wrong input."
prompts = chain([prompt_msg], repeat('\n'.join([bad_input_msg, prompt_msg])))
replies = map(input, prompts)
numeric_replies = filter(str.isdigit, replies)
ages = map(int, numeric_replies)
positive_ages = filter((0).__lt__, ages)
not_too_big_ages = filter((120).__ge__, positive_ages)
valid_response = next(not_too_big_ages)
print(valid_response)
But in the case when there are many rules, it's better to implement a function performing a logical conjunction. In the following example I will use a ready one from here:
from functools import partial
from itertools import chain, repeat
from lz.logical import conjoin
def is_one_letter(string: str) -> bool:
return len(string) == 1
rules = [str.isalpha, str.isupper, is_one_letter, 'C'.__le__, 'P'.__ge__]
prompt_msg = "Enter a letter (C-P): "
bad_input_msg = "Wrong input."
prompts = chain([prompt_msg], repeat('\n'.join([bad_input_msg, prompt_msg])))
replies = map(input, prompts)
valid_response = next(filter(conjoin(*rules), replies))
print(valid_response)
Enter a letter (C-P): 5
Wrong input.
Enter a letter (C-P): f
Wrong input.
Enter a letter (C-P): CDE
Wrong input.
Enter a letter (C-P): Q
Wrong input.
Enter a letter (C-P): N
N
Unfortunately, if someone needs a custom message for each failed case, then, I'm afraid, there is no pretty functional way. Or, at least, I couldn't find one.
You can do that to enable search in ng-keypress
enter for input text and in ng-click
for the icon:
<input type="text" ng-model="searchText" ng-keypress="keyEnter(this,$event)" />
<button ng-click="check(searchText)">Check!</button>
in the controller
$scope.search = function (searchText) {
console.log(searchText);
}
$scope.keyEnter = function (serachText,$event) {
var keyCode = $event.which || $event.keyCode;
if (keyCode === 13) {//KeyCode for Enter key
console.log(searchText);
}
}
Since column-ordering doesn't work in Bootstrap 4 beta as described in the code provided in the revisited answer above, you would need to use the following (as indicated in the codeply 4 Flexbox order demo - alpha/beta links that were provided in the answer).
<div class="container">
<div class="row">
<div class="col-3 col-md-6">
<div class="card card-block">1</div>
</div>
<div class="col-6 col-md-12 flex-md-last">
<div class="card card-block">3</div>
</div>
<div class="col-3 col-md-6 ">
<div class="card card-block">2</div>
</div>
</div>
Note however that the "Flexbox order demo - beta" goes to an alpha codebase, and changing the codebase to Beta (and running it) results in the divs incorrectly displaying in a single column -- but that looks like a codeply issue since cutting and pasting the code out of codeply works as described.
To Restart service in Android O
or more ie OS >28 Use this code KOTLIN VERSION
1) Add permission in manifest
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
2) Create a Class
and extend it with BroadcastReceiver
import android.content.BroadcastReceiver
import android.content.Context
import android.content.Intent
import android.os.Build
import android.util.Log

Log.d("BootCompletedReceiver", "starting service...")
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
ContextCompat.startForegroundService(context, Intent(context, YourServiceClass::class.java))
} else {
context.startService(Intent(context, YourServiceClass::class.java))
}
}
}
3) Declare in Manifest file like this under application tag

I think you're looking for the ndenumerate.
>>> a =numpy.array([[1,2],[3,4],[5,6]])
>>> for (x,y), value in numpy.ndenumerate(a):
... print x,y
...
0 0
0 1
1 0
1 1
2 0
2 1
Regarding the performance. It is a bit slower than a list comprehension.
X = np.zeros((100, 100, 100))
%timeit list([((i,j,k), X[i,j,k]) for i in range(X.shape[0]) for j in range(X.shape[1]) for k in range(X.shape[2])])
1 loop, best of 3: 376 ms per loop
%timeit list(np.ndenumerate(X))
1 loop, best of 3: 570 ms per loop
If you are worried about the performance you could optimise a bit further by looking at the implementation of ndenumerate
, which does 2 things, converting to an array and looping. If you know you have an array, you can call the .coords
attribute of the flat iterator.
a = X.flat
%timeit list([(a.coords, x) for x in a.flat])
1 loop, best of 3: 305 ms per loop
You can hit the key q (for quit) and it should take you to the prompt.
Please see this link.
In addition to the previous answers, you can also do Ctrl + A, and then enter colon (:), and you will notice a little input box at the bottom left. Type 'quit' and Enter to leave the current screen session. Note that this will remove your screen session.
Ctrl + A and then K will only kill the current window in the current session, not the whole session. A screen session consists of windows, which can be created using subsequent Ctrl + A followed by C. These windows can be viewed in a list using Ctrl + A + ".
Intro: I assume that you have a matrix X
where each row/line is a sample/observation and each column is a variable/feature (this is the expected input for any sklearn
ML function by the way -- X.shape
should be [number_of_samples, number_of_features]
).
Core of method: The main idea is to normalize/standardize i.e. µ = 0
and s = 1
your features/variables/columns of X
, individually, before applying any machine learning model.
StandardScaler()
will normalize the features i.e. each column of X, INDIVIDUALLY, so that each column/feature/variable will have µ = 0
and s = 1
.
P.S: I find the most upvoted answer on this page, wrong. I am quoting "each value in the dataset will have the sample mean value subtracted" -- This is neither true nor correct.
See also: How and why to Standardize your data: A python tutorial
Example:
from sklearn.preprocessing import StandardScaler
import numpy as np
# 4 samples/observations and 2 variables/features
data = np.array([[0, 0], [1, 0], [0, 1], [1, 1]])
scaler = StandardScaler()
scaled_data = scaler.fit_transform(data)
print(data)
[[0, 0],
[1, 0],
[0, 1],
[1, 1]])
print(scaled_data)
[[-1. -1.]
[ 1. -1.]
[-1. 1.]
[ 1. 1.]]
Verify that the mean of each feature (column) is 0:
scaled_data.mean(axis = 0)
array([0., 0.])
Verify that the std of each feature (column) is 1:
scaled_data.std(axis = 0)
array([1., 1.])
The maths:
UPDATE 08/2020: Concerning the input parameters with_mean
and with_std
to False
/True
, I have provided an answer here: StandardScaler difference between “with_std=False or True” and “with_mean=False or True”
import operator
sorted_x = sorted(x, key=operator.attrgetter('score'))

I came across this implementation in Codepen. I hope you find it helpful.
this.on('hidden.bs.modal', function(){
$(this).find('iframe').html("").attr("src", "");
});
I had this problem. I had to make my class extend ListActivity rather than Activity, and rename my list in the XML to android:id="@android:id/list"
\ef <function_name>
in psql. It will give the whole function with editable text.
With Linq

In irb:
>>d = DateTime.now

>> "#{d.hour.to_i - d.zone.to_i}:#{d.min}:#{d.sec}"
=> "11:16:41"
will convert the time to the utc. But as posted if it is just Time you can use:
Time.now.utc
and get it straight away.
Linux operating system
Apache web server
MySQL database
and PHP
Reference: LAMP (software bundle)
The "stack" term means stack! That means if you have experience in working with these technologies/framework or not. Since all these come together in a LAMP package, which you can download and install, they call it a stack.
Just a slight correction on the others in SQL Server (schema prefix is becoming more important!):
SELECT name
FROM sys.columns
WHERE [object_id] = OBJECT_ID('dbo.tablename');
Keep in mind that it's the user that is running the oracle database that must have write permissions to the /defaultdir directory, not the user logged into oracle. Typically you're running the database as the user "Oracle". It's not the same user (necessarily) that you created the external table with.
Check your directory permissions, too.
You could use a Data URI to supply the image data, for example:
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
<image width="20" height="20" xlink:href="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg=="/>
</svg>
The image will go through all normal svg transformations.
But this technique has disadvantages, for example the image will not be cached by the browser
Consider below example
We will consider the integer and fractional part separately.
The integral part is easy, 2 = 10.
For the fractional part:
0.625 × 2 = 1.25 1 Generate 1 and continue with the rest.
0.25 × 2 = 0.5 0 Generate 0 and continue.
0.5 × 2 = 1.0 1 Generate 1 and nothing remains.
So 0.625 = 0.101, and 2.625 = 10.101.
See this link for more information.
I much prefer to use sprintf
which is available in base R.
sprintf("%0.1f%%", .7293827 * 100)
[1] "72.9%"
I especially like sprintf
because you can also insert strings.
sprintf("People who prefer %s over %s: %0.4f%%",
"Coke Classic",
"New Coke",
.999999 * 100)
[1] "People who prefer Coke Classic over New Coke: 99.9999%"
It's especially useful to use sprintf
with things like database configurations; you just read in a yaml file, then use sprintf to populate a template without a bunch of nasty paste0
's.
This pattern is especially useful for rmarkdown reports, when you have a lot of text and a lot of values to aggregate.
Setup / aggregation:
library(data.table) ## for aggregate
approval <- data.table(year = trunc(time(presidents)),
pct = as.numeric(presidents) / 100,
president = c(rep("Truman", 32),
rep("Eisenhower", 32),
rep("Kennedy", 12),
rep("Johnson", 20),
rep("Nixon", 24)))
approval_agg <- approval[i = TRUE,
j = .(ave_approval = mean(pct, na.rm=T)),
by = president]
approval_agg
# president ave_approval
# 1: Truman 0.4700000
# 2: Eisenhower 0.6484375
# 3: Kennedy 0.7075000
# 4: Johnson 0.5550000
# 5: Nixon 0.4859091
Using sprintf
with vectors of text and numbers, outputting to cat
just for newlines.
approval_agg[, sprintf("%s approval rating: %0.1f%%",
president,
ave_approval * 100)] %>%
cat(., sep = "\n")
#
# Truman approval rating: 47.0%
# Eisenhower approval rating: 64.8%
# Kennedy approval rating: 70.8%
# Johnson approval rating: 55.5%
# Nixon approval rating: 48.6%
Finally, for my own selfish reference, since we're talking about formatting, this is how I do commas with base R:
30298.78 %>% round %>% prettyNum(big.mark = ",")
[1] "30,299"
Below shared for specific given property
searchContent:function(s, arr,propertyName){
var matches = [];
var propertyNameString=this.propertyNameToStr(propertyName);
for (var i = arr.length; i--; ){
if((""+Object.getOwnPropertyDescriptor(arr[i], propertyNameString).value).indexOf(s) > -1)
matches.push(arr[i]);
}
return matches;
},
propertyNameToStr: function (propertyFunction) {
return /\.([^\.;]+);?\s*\}$/.exec(propertyFunction.toString())[1];
}
//usage as below
result=$localStorage.searchContent(cabNo,appDataObj.getAll(),function() { dummy.cabDriverName; })
The command looks quite fine. Could you try to run -v (verbose mode) and then we can figure out what it is wrong on the authentication?
Also as mention in the other answer, maybe could be this issue - that you need to convert the keys (answered already here): How to convert SSH keypairs generated using PuttyGen(Windows) into key-pairs used by ssh-agent and KeyChain(Linux) OR http://winscp.net/eng/docs/ui_puttygen (depending what you need)
just use:

..where the '4000' is m.second
Try this,this is working for me in angular JS
let fileToUpload = `${documentLocation}/${documentType}.pdf`;
let absoluteFilePath = path.resolve(__dirname, fileToUpload);
console.log(`Uploading document ${absoluteFilePath}`);
element.all(by.css("input[type='file']")).sendKeys(absoluteFilePath);
I wanted to suppress the prompt that asks if you wish to update links to another workbook when my workbook is manually opened in Excel (as opposed to opening it programmatically via VBA). I tried including: Application.AskToUpdateLinks = False
as the first line in my Auto_Open()
macro but that didn't work. I discovered however that if you put it instead in the Workbook_Open()
function in the ThisWorkbook
module, it works brilliantly - the dialog is suppressed but the update still occurs silently in the background.
Private Sub Workbook_Open()
' Suppress dialog & update automatically without asking
Application.AskToUpdateLinks = False
End Sub
I tend to create a static class containing basic functions for cases like these. They allow me write expressions like
var myValues myItems.Select(x => x.Value).Where(Predicates.IsNotNull);
And the collection of predicate functions:
public static class Predicates
{
public static bool IsNull<T>(T value) where T : class
{
return value == null;
}
public static bool IsNotNull<T>(T value) where T : class
{
return value != null;
}
public static bool IsNull<T>(T? nullableValue) where T : struct
{
return !nullableValue.HasValue;
}
public static bool IsNotNull<T>(T? nullableValue) where T : struct
{
return nullableValue.HasValue;
}
public static bool HasValue<T>(T? nullableValue) where T : struct
{
return nullableValue.HasValue;
}
public static bool HasNoValue<T>(T? nullableValue) where T : struct
{
return !nullableValue.HasValue;
}
}
You only get that message if you try to use Designer or diagrams. If you use t-SQL it works fine:
Select *
into newdb.dbo.newtable
from olddb.dbo.yourtable
where olddb.dbo.yourtable
has been created in 2008 exactly as you want the table to be in 2012
If you want all the CSS
thats on your webpage in your IFrame
, try this:
var headClone, iFrameHead;
// Create a clone of the web-page head
headClone = $('head').clone();
// Find the head of the the iFrame we are looking for
iFrameHead = $('#iframe').contents().find('head');
// Replace 'iFrameHead with your Web page 'head'
iFrameHead.replaceWith(headClone);
// You should now have all the Web page CSS in the Iframe
Good Luck.
Since the name is likely to change in future versions of Android (currently the latest is AppCompatActivity
but it will probably change at some point), I believe a good thing to have is a class Activity
that extends AppCompatActivity
and then all your activities extend from that one. If tomorrow, they change the name to AppCompatActivity2
for instance you will have to change it just in one place.
iOS 13 bit my app in the butt here. If you've noticed behavior change as of iOS 13 just set the following before you push it:
yourVC.modalPresentationStyle = UIModalPresentationFullScreen;
You may also need to set it in your .storyboard in the Attributes inspector (set Presentation to Full Screen).
This will make your app behave as it did in prior versions of iOS.
Sadly @Andrés Montoya answer has a flaw which is related to how he compares the obj. I found a solution here which should solve this:
const now = Date.now().valueOf() / 1000
if (typeof decoded.exp !== 'undefined' && decoded.exp < now) {
throw new Error(`token expired: ${JSON.stringify(decoded)}`)
}
if (typeof decoded.nbf !== 'undefined' && decoded.nbf > now) {
throw new Error(`token expired: ${JSON.stringify(decoded)}`)
}
Thanks to thejohnfreeman!
i think phil is right request option is available till the page load. so if we want to sent value to another page we want to set the in the hidden tag or in side the session if you just need the value only on another page and not more than that then hidden tags are best option if you need that value on more than one page at that time session is the better option than hidden tags.
Like mentioned earlier, I'd recommend boost lexical_cast. Not only does it have a fairly nice syntax:
#include <boost/lexical_cast.hpp>
std::string s = boost::lexical_cast<std::string>(i);
it also provides some safety:
try{
std::string s = boost::lexical_cast<std::string>(i);
}catch(boost::bad_lexical_cast &){
...
}
The precision of double
and float
is fixed by their size and the way the IEEE floating point types are implemented.
The number of decimal digits in the output, on the other hand, is a matter of formatting. You are correct that typing the same constant over and over is a bad idea. You should declare a string constant instead, and use its symbolic representation.
private static final String DBL_FMT = "##.####";
Using a symbolic representation would let you change precision in all places the constant is used without searching through your code.

Getting the data after the hashmark in a query string is simple. Here is an example used for when a client accesses a glossary of terms from a book. It takes the name anchor delivered (#tesla), and delivers the client to that term and highlights the term and its description in blue so its easy to see.
A. setup your strings with a div id, so the name anchor goes where its supposed to and the javascript can change the text colors
<div id="tesla">Tesla</div>
<div id="tesla1">An energy company</div>
B. Use Javascript to do the heavy work, on the server side, inserted in your PHP page, or wherever..
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
C. I am launching the java function automatically when the page is loaded.
<script>
$( document ).ready(function() {
D. get the anchor (#tesla) from the url received by the server
var myhash1 = $(location).attr('hash'); //myhash1 == #tesla
E. trim the hash sign off of it
myhash1 = myhash1.substr(1) //myhash1 == tesla
F. I need to highlight the term and the description so i create a new var
var myhash2 = '1';
myhash2 = myhash1.concat(myhash2); //myhash2 == tesla1
G. Now I can manipulate the text color for the term and description
var elem = document.getElementById(myhash1);
elem.style.color = 'blue';
elem = document.getElementById(myhash2);
elem.style.color = 'blue';
});
</script>
H. This works. client clicks link on client side (xyz.com#tesla) and goes right to the term. the term and the description are highlighted in blue by javascript for quick reading .. all other entries left in black..
May this code helps you.

You can use inbuilt library pickle
This library allows you to save any object in python to a file
This library will maintain the format as well
import pickle
with open('/content/list_1.txt', 'wb') as fp:
pickle.dump(list_1, fp)
you can also read the list back as an object using same library
with open ('/content/list_1.txt', 'rb') as fp:
list_1 = pickle.load(fp)

Visual Leak Detector (VLD) is a free, robust, open-source memory leak detection system for Visual C++.
When you run your program under the Visual Studio debugger, Visual Leak Detector will output a memory leak report at the end of your debugging session. The leak report includes the full call stack showing how any leaked memory blocks were allocated. Double-click on a line in the call stack to jump to that file and line in the editor window.
If you only have crash dumps, you can use the Windbg !heap -l
command, it will detect leaked heap blocks. Better open the gflags option: “Create user mode stack trace database”, then you will see the memory allocation call stack.
I had a similar issue and this is what worked for me.
Add the NodeSource package signing key:
curl -sSL https://deb.nodesource.com/gpgkey/nodesource.gpg.key | sudo apt-key add -
# wget can also be used:
# wget --quiet -O - https://deb.nodesource.com/gpgkey/nodesource.gpg.key | sudo apt-key add -
Add the desired NodeSource repository:
# Replace with the branch of Node.js or io.js you want to install: node_6.x, node_12.x, etc...
VERSION=node_12.x
# The below command will set this correctly, but if lsb_release isn't available, you can set it manually:
# - For Debian distributions: jessie, sid, etc...
# - For Ubuntu distributions: xenial, bionic, etc...
# - For Debian or Ubuntu derived distributions your best option is to use the codename corresponding to the upstream release your distribution is based off. This is an advanced scenario and unsupported if your distribution is not listed as supported per earlier in this README.
DISTRO="$(lsb_release -s -c)"
echo "deb https://deb.nodesource.com/$VERSION $DISTRO main" | sudo tee /etc/apt/sources.list.d/nodesource.list

Just encountered the same issue. The problem is because of django-registration
incompatible with django 1.7 user model.
A simple fix is to change these lines of code, at your installed django-registration
module::
try:
from django.contrib.auth import get_user_model
User = get_user_model()
except ImportError:
from django.contrib.auth.models import User
to::
from django.conf import settings
try:
from django.contrib.auth import get_user_model
User = settings.AUTH_USER_MODEL
except ImportError:
from django.contrib.auth.models import User
Mine is at .venv/local/lib/python2.7/site-packages/registration/models.py

My problem was that I sillily concluded bootstrap documentation is the latest one.
If you are using Bootstrap 4, the necessary working tab markub is: http://v4-alpha.getbootstrap.com/components/navs/#javascript-behavior
<ul>
<li class="nav-item"><a class="active" href="#a" data-toggle="tab">a</a></li>
<li class="nav-item"><a href="#b" data-toggle="tab">b</a></li>
</ul>
<div class="tab-content">
<div class="tab-pane active" id="a">a</div>
<div class="tab-pane" id="b">b</div>
</div>
There are probably embedded tabs (CHAR(9)
) etc. as well. You can find out what other characters you need to replace (we have no idea what your goal is) with something like this:
DECLARE @var NVARCHAR(255), @i INT;
SET @i = 1;
SELECT @var = AccountType FROM dbo.Account
WHERE AccountNumber = 200
AND AccountType LIKE '%Daily%';
CREATE TABLE #x(i INT PRIMARY KEY, c NCHAR(1), a NCHAR(1));
WHILE @i <= LEN(@var)
BEGIN
INSERT #x
SELECT SUBSTRING(@var, @i, 1), ASCII(SUBSTRING(@var, @i, 1));
SET @i = @i + 1;
END
SELECT i,c,a FROM #x ORDER BY i;
You might also consider doing better cleansing of this data before it gets into your database. Cleaning it every time you need to search or display is not the best approach.
>>> dict(zip(keys, values))
{0: 'Hi', 1: 'I', 2: 'am', 3: 'John'}

If you want to hide nav bar for one activity you can use this:
<activity
android:name="Activity Name"
android:theme="@android:style/Theme.Black.NoTitleBar"

Take a look at this thread: Print ZPL codes to ZEBRA printer using PrintDocument class.
Specifically the OP pick this function from the answers to the thread:
[DllImport("kernel32.dll", SetLastError = true)]
static extern SafeFileHandle CreateFile(string lpFileName, FileAccess dwDesiredAccess,
uint dwShareMode, IntPtr lpSecurityAttributes, FileMode dwCreationDisposition,
uint dwFlagsAndAttributes, IntPtr hTemplateFile);
private void Print()
{
// Command to be sent to the printer
string command = "^XA^FO10,10,^AO,30,20^FDFDTesting^FS^FO10,30^BY3^BCN,100,Y,N,N^FDTesting^FS^XZ";
// Create a buffer with the command
Byte[] buffer = new byte[command.Length];
buffer = System.Text.Encoding.ASCII.GetBytes(command);
// Use the CreateFile external func to connect to the LPT1 port
SafeFileHandle printer = CreateFile("LPT1:", FileAccess.ReadWrite, 0, IntPtr.Zero, FileMode.Open, 0, IntPtr.Zero);
// Aqui verifico se a impressora é válida
if (printer.IsInvalid == true)
{
return;
}
// Open the filestream to the lpt1 port and send the command
FileStream lpt1 = new FileStream(printer, FileAccess.ReadWrite);
lpt1.Write(buffer, 0, buffer.Length);
// Close the FileStream connection
lpt1.Close();
}
Just use the beef class:
public <T> T beefmarshal( Class<beef> beefClass, InputBeef inputBeef )
throws JAXBException {
String packageName = docClass.getPackage().getBeef();
JAXBContext beef = JAXBContext.newInstance( packageName );
Unmarshaller u = beef.createBeef();
JAXBElement<T> doc = (JAXBElement<T>)u.beefmarshal( inputBeef );
return doc.getBeef();
}
Did you try rebooting your Mac and your device? Lame answer, but I always try that first.
This one works fine
use try { as above
use Catch as above but comment out the echo lines
} catch (phpmailerException $e) {
//echo $e->errorMessage(); //Pretty error messages from PHPMailer
} catch (Exception $e) {
//echo $e->getMessage(); //Boring error messages from anything else!
}
Then add this
if ($e) {
//enter yor error message or redirect the user
} else {
//do something else
}
ffmpeg -vfilters "rotate=90" -i input.mp4 output.mp4

Although @serge answer is correct but i compared time consumption of his way against xmlpath and i found the xmlpath is so faster. I'll write the compare code and you can check it by yourself. This is @serge way:
DECLARE @startTime datetime2;
DECLARE @endTime datetime2;
DECLARE @counter INT;
SET @counter = 1;
set nocount on;
declare @YourTable table (ID int, Name nvarchar(50))
WHILE @counter < 1000
BEGIN
insert into @YourTable VALUES (ROUND(@counter/10,0), CONVERT(NVARCHAR(50), @counter) + 'CC')
SET @counter = @counter + 1;
END
SET @startTime = GETDATE()
;WITH Partitioned AS
(
SELECT
ID,
Name,
ROW_NUMBER() OVER (PARTITION BY ID ORDER BY Name) AS NameNumber,
COUNT(*) OVER (PARTITION BY ID) AS NameCount
FROM @YourTable
),
Concatenated AS
(
SELECT ID, CAST(Name AS nvarchar) AS FullName, Name, NameNumber, NameCount FROM Partitioned WHERE NameNumber = 1
UNION ALL
SELECT
P.ID, CAST(C.FullName + ', ' + P.Name AS nvarchar), P.Name, P.NameNumber, P.NameCount
FROM Partitioned AS P
INNER JOIN Concatenated AS C ON P.ID = C.ID AND P.NameNumber = C.NameNumber + 1
)
SELECT
ID,
FullName
FROM Concatenated
WHERE NameNumber = NameCount
SET @endTime = GETDATE();
SELECT DATEDIFF(millisecond,@startTime, @endTime)
--Take about 54 milliseconds
And this is xmlpath way:
DECLARE @startTime datetime2;
DECLARE @endTime datetime2;
DECLARE @counter INT;
SET @counter = 1;
set nocount on;
declare @YourTable table (RowID int, HeaderValue int, ChildValue varchar(5))
WHILE @counter < 1000
BEGIN
insert into @YourTable VALUES (@counter, ROUND(@counter/10,0), CONVERT(NVARCHAR(50), @counter) + 'CC')
SET @counter = @counter + 1;
END
SET @startTime = GETDATE();
set nocount off
SELECT
t1.HeaderValue
,STUFF(
(SELECT
', ' + t2.ChildValue
FROM @YourTable t2
WHERE t1.HeaderValue=t2.HeaderValue
ORDER BY t2.ChildValue
FOR XML PATH(''), TYPE
).value('.','varchar(max)')
,1,2, ''
) AS ChildValues
FROM @YourTable t1
GROUP BY t1.HeaderValue
SET @endTime = GETDATE();
SELECT DATEDIFF(millisecond,@startTime, @endTime)
--Take about 4 milliseconds
