Yes, if you have URL wrappers disabled you should use sockets or, even better, the cURL library.
If it's part of your site then refer to it with the file system path, not the web URL. /var/www/...
, rather than http://domain.tld/...
.
Since you are not allowed to put more than two conditions in one condition group (And | Or) you have to create an extra nested group (MSDN). The expression A AND B AND C
looks like this:
<And>
A
<And>
B
C
</And>
</And>

You can use the jQuery ajax method link if you want to pass data from client to server.
In this case you can use $_SERVER['HTTP_USER_AGENT']
variable to found browser user agent.
I had the same problem as you and I did the following to solve it:
**IMAGEVIEW**.setImageResource(getActivity()
.getResources()
.getIdentifier("**IMG**", "drawable", getActivity()
.getPackageName()));
The really simplified answer is that the kernel runs in kernel space, and normal programs run in user space. User space is basically a form of sand-boxing -- it restricts user programs so they can't mess with memory (and other resources) owned by other programs or by the OS kernel. This limits (but usually doesn't entirely eliminate) their ability to do bad things like crashing the machine.
The kernel is the core of the operating system. It normally has full access to all memory and machine hardware (and everything else on the machine). To keep the machine as stable as possible, you normally want only the most trusted, well-tested code to run in kernel mode/kernel space.
The stack is just another part of memory, so naturally it's segregated right along with the rest of memory.
The solution is in the link that you provided in your question:
datetime.combine(date.today(), time()) + timedelta(hours=1)
Full example:
from datetime import date, datetime, time, timedelta
dt = datetime.combine(date.today(), time(23, 55)) + timedelta(minutes=30)
print dt.time()
Output:
00:25:00
Link to the PEP discussing the new bool type in Python 2.3: http://www.python.org/dev/peps/pep-0285/.
When converting a bool to an int, the integer value is always 0 or 1, but when converting an int to a bool, the boolean value is True for all integers except 0.
>>> int(False)
0
>>> int(True)
1
>>> bool(5)
True
>>> bool(-5)
True
>>> bool(0)
False
There could be a lot of reason when you get this kind of error:
Check whether you have selected a provisioning profile which includes the valid Code Signing Identity and a valid Bundle Identifier in Settings. (Goto Build Settings->Signing->Provisioning Profile).
Open Keychain Access and click on lock icon at top left, so it will lock the login keychain and then again click to unlock.
Reduce() is..
It was ..
let array=[1,2,3];
function sum(acc,val){ return acc+val;} // => can change to (acc,val)=>acc+val
let answer= array.reduce(sum); // answer is 6
Change to
let array=[1,2,3];
let answer=arrays.reduce((acc,val)=>acc+val);
Also you can use in
let array=[5,4,19,2,7];
function findMax(acc,val)
{
if(val>acc){
acc=val;
}
}
let biggest=arrays.reduce(findMax); // 19
arr = [1, 2, 5, 4, 6, 8, 9, 2, 1, 4, 5, 8, 9]
v = 0
for i in range(len(arr)):
v = v ^ arr[i]
print(value) //6
Try like this
ImageButton imagetrans=(ImageButton)findViewById(R.id.ImagevieID);

There is a new property in CSS3 that you can use to change the way the box model calculates width/height, it's called box-sizing.
By setting this property with the value "border-box" it makes whichever element you apply it to not stretch when you add a padding or border. If you define something with 100px width, and 10px padding, it will still be 100px wide.
box-sizing: border-box;
See here for browser support. It does not work for IE7 and lower, however, I believe that Dean Edward's IE7.js adds support for it. Enjoy :)
OK, first of all, you don't have to get a reference to the module into a different name; you already have a reference (from the import
) and you can just use it. If you want a different name just use import swineflu as f
.
Second, you are getting a reference to the class rather than instantiating the class.
So this should be:
import swineflu
fibo = swineflu.fibo() # get an instance of the class
fibo.f() # call the method f of the instance
A bound method is one that is attached to an instance of an object. An unbound method is, of course, one that is not attached to an instance. The error usually means you are calling the method on the class rather than on an instance, which is exactly what was happening in this case because you hadn't instantiated the class.
I've used next function to get scrollbar height/width:
function getBrowserScrollSize(){
var css = {
"border": "none",
"height": "200px",
"margin": "0",
"padding": "0",
"width": "200px"
};
var inner = $("<div>").css($.extend({}, css));
var outer = $("<div>").css($.extend({
"left": "-1000px",
"overflow": "scroll",
"position": "absolute",
"top": "-1000px"
}, css)).append(inner).appendTo("body")
.scrollLeft(1000)
.scrollTop(1000);
var scrollSize = {
"height": (outer.offset().top - inner.offset().top) || 0,
"width": (outer.offset().left - inner.offset().left) || 0
};
outer.remove();
return scrollSize;
}
This jQuery-based solutions works in IE7+ and all other modern browsers (including mobile devices where scrollbar height/width will be 0).
I know this post is super old, but I have an answer that's surprisingly missing from the above and is also much simpler than most.
<Button>
<Button.Resources>
<Style TargetType="Border">
<Setter Property="CornerRadius" Value="5"/>
</Style>
</Button.Resources>
</Button>
Since the default ControlTemplate for the Button control uses a Border element, adding a style for Border to the Button's resources applies that style to that Border. This lets you add rounded corners without having to make your own ControlTemplate and without any code. It also works on all varieties of Button (e.g. ToggleButton and RepeatButton).
There is one way to react to a kill -9: that is to have a separate process that monitors the process being killed and cleans up after it if necessary. This would probably involve IPC and would be quite a bit of work, and you can still override it by killing both processes at the same time. I assume it will not be worth the trouble in most cases.
Whoever kills a process with -9 should theoretically know what he/she is doing and that it may leave things in an inconsistent state.
There's no difference between the file extensions, and they are used interchangeably. I guess the 3-letter version stems from the DOS era...
However, there are different "flavors" of JPEG files. Most notably the JFIF standard and the EXIF standard. Most often these just use .jpg
or .jpeg
as file extensions, JFIF sometimes uses .jif
or .jfif
.
Simple way? Use strip_tags()
:
$str = strip_tags($input);
You can also use filter_var()
for that:
$str = filter_var($input, FILTER_SANITIZE_STRING);
The advantage of filter_var()
is that you can control the behaviour by, for example, stripping or encoding low and high characters.
Here is a list of sanitizing filters.
Well that's pretty easy actually with GCD. A typical workflow would be something like this:
dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0ul);
dispatch_async(queue, ^{
// Perform async operation
// Call your method/function here
// Example:
// NSString *result = [anObject calculateSomething];
dispatch_sync(dispatch_get_main_queue(), ^{
// Update UI
// Example:
// self.myLabel.text = result;
});
});
For more on GCD you can take a look into Apple's documentation here
If you're in a situation like @Keith you could try:
print(a.__dict__)
It goes against what I would consider good style but if you're just trying to debug then it should do what you want.
This page describes an answer with awk
awk '{while(match($0,"[$]{[^}]*}")) {var=substr($0,RSTART+2,RLENGTH -3);gsub("[$]{"var"}",ENVIRON[var])}}1' < input.txt > output.txt
If you intend to use this output in production, then use the Trace class members. This makes the code portable, you can wire up different types of listeners and output to the console window, debug window, log file, or whatever else you like.
If this is just some temporary debugging code that you're using to verify that certain code is being executed or has the correct values, then use the Debug class as Zach suggests.
If you absolutely must use the console, then you can attach a console in the program's Main
method.
Try (in your <head> section, or existing css definitions)...
<style>
body {
margin:0;
padding:0;
}
</style>
(1) SQLite has a built in rowid
pseudo-column so this works:
sqldf("select min(rowid) rowid, id, string
from test
group by id")
giving:
rowid id string
1 1 1 A
2 3 2 B
3 5 3 C
4 7 4 D
5 9 5 E
(2) Also sqldf
itself has a row.names=
argument:
sqldf("select min(cast(row_names as real)) row_names, id, string
from test
group by id", row.names = TRUE)
giving:
id string
1 1 A
3 2 B
5 3 C
7 4 D
9 5 E
(3) A third alternative which mixes the elements of the above two might be even better:
sqldf("select min(rowid) row_names, id, string
from test
group by id", row.names = TRUE)
giving:
id string
1 1 A
3 2 B
5 3 C
7 4 D
9 5 E
Note that all three of these rely on a SQLite extension to SQL where the use of min
or max
is guaranteed to result in the other columns being chosen from the same row. (In other SQL-based databases that may not be guaranteed.)
The big thing to get your head around is that the File
class tries to represent a view of what Sun like to call "hierarchical pathnames" (basically a path like c:/foo.txt
or /usr/muggins
). This is why you create files in terms of paths. The operations you are describing are all operations upon this "pathname".
getPath()
fetches the path that the File was created with (../foo.txt
)getAbsolutePath()
fetches the path that the File was created with, but includes information about the current directory if the path is relative (/usr/bobstuff/../foo.txt
)getCanonicalPath()
attempts to fetch a unique representation of the absolute path to the file. This eliminates indirection from ".." and "." references (/usr/foo.txt
).Note I say attempts - in forming a Canonical Path, the VM can throw an IOException
. This usually occurs because it is performing some filesystem operations, any one of which could fail.
Since nobody so far felt fit to point out why what you're trying doesn't work:
NA == NA
doesn't return TRUE
, it returns NA
(since comparing to undefined values should yield an undefined result). apply
on an atomic vector. You can't use apply
to loop over the elements in a column. a$x
, which is just the column (an atomic vector).I'd fix up 3. to get to a$x[is.na(a$x)] <- 0
declare @starttime datetime = '2012-03-07 22:58:00'
SELECT BookingId, StartTime
FROM Booking
WHERE ABS( DATEDIFF( minute, StartTime, @starttime ) ) <= 60
Try this, works for me: ls -d /a/b/c/*
This might work for you:
printf "{new\nto\nlinux}" | paste -sd' '
{new to linux}
or:
printf "{new\nto\nlinux}" | tr '\n' ' '
{new to linux}
or:
printf "{new\nto\nlinux}" |sed -e ':a' -e '$!{' -e 'N' -e 'ba' -e '}' -e 's/\n/ /g'
{new to linux}
The answer is Yes if the query is run multiple times at once, because each transaction won't need to wait for the others to complete. However, If the query is run once on its own then the answer is No.
Yes. There's a significant probability that careful use of WITH(NOLOCK) will speed up your database overall. It means that other transactions won't have to wait for this SELECT statement to finish, but on the other hand, other transactions will slow down as they're now sharing their processing time with a new transaction.
Be careful to only use WITH (NOLOCK)
in SELECT statements on tables that have a clustered index.
WITH(NOLOCK) is often exploited as a magic way to speed up database read transactions.
The result set can contain rows that have not yet been committed, that are often later rolled back.
If WITH(NOLOCK) is applied to a table that has a non-clustered index then row-indexes can be changed by other transactions as the row data is being streamed into the result-table. This means that the result-set can be missing rows or display the same row multiple times.
READ COMMITTED adds an additional issue where data is corrupted within a single column where multiple users change the same cell simultaneously.
Dump the configuration:
$ nginx -T
...
server {
...
location / {
root /usr/share/nginx/html;
...
}
...
}
What you get might be different since it depends on how your nginx
was configured/installed.
References:
Update: There's some confusion on the issue of if/when the -T
option was added to nginx
. It was documented in the man page by vl-homutov on 2015 June 16, which became part of the v1.9.2 release. It's even mentioned in the release notes. The -T
option has been present in every nginx
release since, including the one available on Ubuntu 16.04.1 LTS:
root@23cc8e58640e:/# nginx -h
nginx version: nginx/1.10.0 (Ubuntu)
Usage: nginx [-?hvVtTq] [-s signal] [-c filename] [-p prefix] [-g directives]
Options:
-?,-h : this help
-v : show version and exit
-V : show version and configure options then exit
-t : test configuration and exit
-T : test configuration, dump it and exit
-q : suppress non-error messages during configuration testing
-s signal : send signal to a master process: stop, quit, reopen, reload
-p prefix : set prefix path (default: /usr/share/nginx/)
-c filename : set configuration file (default: /etc/nginx/nginx.conf)
-g directives : set global directives out of configuration file
I was annoyed that you had to always include the namespace and the folder in the string. I wanted to simplify the access to the embedded resources. This is why I wrote this little class. Feel free to use and improve!
Usage:
using(Stream stream = EmbeddedResources.ExecutingResources.GetStream("filename.txt"))
{
//...
}
Class:
public class EmbeddedResources
{
private static readonly Lazy<EmbeddedResources> _callingResources = new Lazy<EmbeddedResources>(() => new EmbeddedResources(Assembly.GetCallingAssembly()));
private static readonly Lazy<EmbeddedResources> _entryResources = new Lazy<EmbeddedResources>(() => new EmbeddedResources(Assembly.GetEntryAssembly()));
private static readonly Lazy<EmbeddedResources> _executingResources = new Lazy<EmbeddedResources>(() => new EmbeddedResources(Assembly.GetExecutingAssembly()));
private readonly Assembly _assembly;
private readonly string[] _resources;
public EmbeddedResources(Assembly assembly)
{
_assembly = assembly;
_resources = assembly.GetManifestResourceNames();
}
public static EmbeddedResources CallingResources => _callingResources.Value;
public static EmbeddedResources EntryResources => _entryResources.Value;
public static EmbeddedResources ExecutingResources => _executingResources.Value;
public Stream GetStream(string resName) => _assembly.GetManifestResourceStream(_resources.Single(s => s.Contains(resName)));
}
Use Navigator:-
The navigator
is an object that contains all information about the client machine's browser.
navigator.appName
returns the name of the client machine's browser.
navigator.appName === 'Microsoft Internet Explorer' || !!(navigator.userAgent.match(/Trident/) || navigator.userAgent.match(/rv:11/)) || (typeof $.browser !== "undefined" && $.browser.msie === 1) ? alert("Please dont use IE.") : alert("This is not IE")

1. SQL or Structured Query Language was developed by IBM for their product "System R".
Later ANSI made it as a Standard on which all Query Languages are based upon and have extended this to create their own DataBase Query Language suits. The first standard was SQL-86 and latest being SQL:2016
2. T-SQL or Transact-SQL was developed by Sybase and later co-owned by Microsoft SQL Server.
3. PL/SQL or Procedural Language/SQL was Oracle Database, known as "Relation Software" that time.
I've documented this in my blog post.
As you are worried about user upload other file by mistake, I would suggest you to use accept=".csv"
in <input>
tag. It will show only csv files in browser when the user uploads the file. If you have found some better solution then please let me know as I am also trying to do same and in the same condition - 'trusted users but trying to avoid mistake'
Data List is a new HTML tag in HTML5 supported browsers. It renders as a text box with some list of options. For Example for Gender Text box it will give you options as Male Female when you type 'M' or 'F' in Text Box.
<input list="Gender">
<datalist id="Gender">
<option value="Male">
<option value="Female>
</datalist>
I would do :
$('#checkbox').on("change", function (e){
if(this.checked){
// Do one thing
}
else{
// Do some other thing
}
});
See : https://www.w3schools.com/jsref/prop_checkbox_checked.asp
Tests
On the Tests
class we will add an @XmlRootElement
annotation. Doing this will let your JAXB implementation know that when a document starts with this element that it should instantiate this class. JAXB is configuration by exception, this means you only need to add annotations where your mapping differs from the default. Since the testData
property differs from the default mapping we will use the @XmlElement
annotation. You may find the following tutorial helpful: http://wiki.eclipse.org/EclipseLink/Examples/MOXy/GettingStarted
package forum11221136;
import javax.xml.bind.annotation.*;
@XmlRootElement
public class Tests {
TestData testData;
@XmlElement(name="test-data")
public TestData getTestData() {
return testData;
}
public void setTestData(TestData testData) {
this.testData = testData;
}
}
TestData
On this class I used the @XmlType
annotation to specify the order in which the elements should be ordered in. I added a testData
property that appeared to be missing. I also used an @XmlElement
annotation for the same reason as in the Tests
class.
package forum11221136;
import java.util.List;
import javax.xml.bind.annotation.*;
@XmlType(propOrder={"title", "book", "count", "testData"})
public class TestData {
String title;
String book;
String count;
List<TestData> testData;
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getBook() {
return book;
}
public void setBook(String book) {
this.book = book;
}
public String getCount() {
return count;
}
public void setCount(String count) {
this.count = count;
}
@XmlElement(name="test-data")
public List<TestData> getTestData() {
return testData;
}
public void setTestData(List<TestData> testData) {
this.testData = testData;
}
}
Demo
Below is an example of how to use the JAXB APIs to read (unmarshal) the XML and populate your domain model and then write (marshal) the result back to XML.
package forum11221136;
import java.io.File;
import javax.xml.bind.*;
public class Demo {
public static void main(String[] args) throws Exception {
JAXBContext jc = JAXBContext.newInstance(Tests.class);
Unmarshaller unmarshaller = jc.createUnmarshaller();
File xml = new File("src/forum11221136/input.xml");
Tests tests = (Tests) unmarshaller.unmarshal(xml);
Marshaller marshaller = jc.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
marshaller.marshal(tests, System.out);
}
}
There is no block comment in VB.NET.
You need to use a '
in front of every line you want to comment out.
In Visual Studio you can use the keyboard shortcuts that will comment/uncomment the selected lines for you:
Ctrl + K, C to comment
Ctrl + K, U to uncomment
You can use the to_pydatetime method to be more explicit:
In [11]: ts = pd.Timestamp('2014-01-23 00:00:00', tz=None)
In [12]: ts.to_pydatetime()
Out[12]: datetime.datetime(2014, 1, 23, 0, 0)
It's also available on a DatetimeIndex:
In [13]: rng = pd.date_range('1/10/2011', periods=3, freq='D')
In [14]: rng.to_pydatetime()
Out[14]:
array([datetime.datetime(2011, 1, 10, 0, 0),
datetime.datetime(2011, 1, 11, 0, 0),
datetime.datetime(2011, 1, 12, 0, 0)], dtype=object)
Those settings (core.whitespace
and apply.whitespace
) are not there to remove trailing whitespace but to:
core.whitespace
: detect them, and raise errors apply.whitespace
: and strip them, but only during patch, not "always automatically"I believe the git hook pre-commit
would do a better job for that (includes removing trailing whitespace)
Note that at any given time you can choose to not run the pre-commit
hook:
git commit --no-verify .
cd .git/hooks/ ; chmod -x pre-commit
Warning: by default, a pre-commit
script (like this one), has not a "remove trailing" feature", but a "warning" feature like:
if (/\s$/) {
bad_line("trailing whitespace", $_);
}
You could however build a better pre-commit
hook, especially when you consider that:
Committing in Git with only some changes added to the staging area still results in an “atomic” revision that may never have existed as a working copy and may not work.
For instance, oldman proposes in another answer a pre-commit
hook which detects and remove whitespace.
Since that hook get the file name of each file, I would recommend to be careful for certain type of files: you don't want to remove trailing whitespace in .md
(markdown) files!

window.location.href = "URL2"
inside a JS block on the page or in an included file; that's assuming you really want to do it on the client. Usually, the server sends the redirect via a 300-series response.
Use the 'EntireColumn' property, that's what it is there for. C# snippet, but should give you a good indication of how to do this:
string rangeQuery = "A1:A1";
Range range = workSheet.get_Range(rangeQuery, Type.Missing);
range = range.EntireColumn;
You may try creating a new project in netbeans and then copy and and paste the files into it. I usually experience this problem when the project wasn't created in netbeans.
see https://github.com/karma-runner/karma/issues/1731#issuecomment-174227054
The files array can be redefined using the CLI as such:
karma start --files=Array("test/Spec/services/myServiceSpec.js")
or escaped:
karma start --files=Array\(\"test/Spec/services/myServiceSpec.js\"\)

Editor warning: This solution is computationally inefficient and may bring down your connection for a large table.
NB - You need to do this first on a test copy of your table!
When I did it, I found that unless I also included AND n1.id <> n2.id
, it deleted every row in the table.
If you want to keep the row with the lowest id
value:
DELETE n1 FROM names n1, names n2 WHERE n1.id > n2.id AND n1.name = n2.name
If you want to keep the row with the highest id
value:
DELETE n1 FROM names n1, names n2 WHERE n1.id < n2.id AND n1.name = n2.name
I used this method in MySQL 5.1
Not sure about other versions.
Update: Since people Googling for removing duplicates end up here
Although the OP's question is about DELETE
, please be advised that using INSERT
and DISTINCT
is much faster. For a database with 8 million rows, the below query took 13 minutes, while using DELETE
, it took more than 2 hours and yet didn't complete.
INSERT INTO tempTableName(cellId,attributeId,entityRowId,value)
SELECT DISTINCT cellId,attributeId,entityRowId,value
FROM tableName;
JSONP stands for “JSON with Padding” and it is a workaround for loading data from different domains. It loads the script into the head of the DOM and thus you can access the information as if it were loaded on your own domain, thus by-passing the cross domain issue.
jsonCallback(
{
"sites":
[
{
"siteName": "JQUERY4U",
"domainName": "http://www.jquery4u.com",
"description": "#1 jQuery Blog for your Daily News, Plugins, Tuts/Tips & Code Snippets."
},
{
"siteName": "BLOGOOLA",
"domainName": "http://www.blogoola.com",
"description": "Expose your blog to millions and increase your audience."
},

(function($) {
var url = 'http://www.jquery4u.com/scripts/jquery4u-sites.json?callback=?';
$.ajax({
type: 'GET',
url: url,
async: false,
jsonpCallback: 'jsonCallback',
contentType: "application/json",
dataType: 'jsonp',
success: function(json) {
console.dir(json.sites);
},
error: function(e) {
console.log(e.message);
}
});
})(jQuery);
Now we can request the JSON via AJAX using JSONP and the callback function we created around the JSON content. The output should be the JSON as an object which we can then use the data for whatever we want without restrictions.
To get the entire contents of a file:
$content = [IO.File]::ReadAllText(".\test.txt")
Number of lines:
([IO.File]::ReadAllLines(".\test.txt")).length
or
(gc .\test.ps1).length
Sort of hackish to include trailing empty line:
[io.file]::ReadAllText(".\desktop\git-python\test.ps1").split("`n").count
Hi You can use a simple query,
select emp_cd, val1, val2, val3,
(val1+val2+val3) as total
from emp;
In case you need to insert a new row,
insert into emp select emp_cd, val1, val2, val3,
(val1+val2+val3) as total
from emp;
In order to update,
update emp set total = val1+val2+val3;
This will update for all comumns
Use the constructor for appending material to the file:
FileOutputStream(File file, boolean append)
Creates a file output stream to write to the file represented by the specified File object.
So to append to a file say "abc.txt" use
FileOutputStream fos=new FileOutputStream(new File("abc.txt"),true);
You can follow uploaded images
Then select which database you want to delete

1st solution (fastest) :
yourDateTime.Year % 100
2nd solution (more elegant in my opinion) :
yourDateTime.ToString("yy")
static_cast
is used for cases where you basically want to reverse an implicit conversion, with a few restrictions and additions. static_cast
performs no runtime checks. This should be used if you know that you refer to an object of a specific type, and thus a check would be unnecessary. Example:
void func(void *data) {
// Conversion from MyClass* -> void* is implicit
MyClass *c = static_cast<MyClass*>(data);
...
}
int main() {
MyClass c;
start_thread(&func, &c) // func(&c) will be called
.join();
}
In this example, you know that you passed a MyClass
object, and thus there isn't any need for a runtime check to ensure this.
dynamic_cast
is useful when you don't know what the dynamic type of the object is. It returns a null pointer if the object referred to doesn't contain the type casted to as a base class (when you cast to a reference, a bad_cast
exception is thrown in that case).
if (JumpStm *j = dynamic_cast<JumpStm*>(&stm)) {
...
} else if (ExprStm *e = dynamic_cast<ExprStm*>(&stm)) {
...
}
You cannot use dynamic_cast
if you downcast (cast to a derived class) and the argument type is not polymorphic. For example, the following code is not valid, because Base
doesn't contain any virtual function:
struct Base { };
struct Derived : Base { };
int main() {
Derived d; Base *b = &d;
dynamic_cast<Derived*>(b); // Invalid
}
An "up-cast" (cast to the base class) is always valid with both static_cast
and dynamic_cast
, and also without any cast, as an "up-cast" is an implicit conversion.
These casts are also called C-style cast. A C-style cast is basically identical to trying out a range of sequences of C++ casts, and taking the first C++ cast that works, without ever considering dynamic_cast
. Needless to say, this is much more powerful as it combines all of const_cast
, static_cast
and reinterpret_cast
, but it's also unsafe, because it does not use dynamic_cast
.
In addition, C-style casts not only allow you to do this, but they also allow you to safely cast to a private base-class, while the "equivalent" static_cast
sequence would give you a compile-time error for that.
Some people prefer C-style casts because of their brevity. I use them for numeric casts only, and use the appropriate C++ casts when user defined types are involved, as they provide stricter checking.
A ramda one liner:
import {
compose,
sum,
values,
} from 'ramda'
export const sumValues = compose(sum, values);
Use:
const summed = sumValues({ 'a': 1 , 'b': 2 , 'c':3 });
This is because your <h1>
is the width of the centercol. Specify a width on the <h1>
and use margin: 0 auto;
if you want it centered.
Or, alternatively, you could float the <h1>
, which would make it only exactly as wide as the text.
Starting git 1.8.5 (Q4 2013), you will be able to "use a Git command, but without having to change directories".
Just like "
make -C <directory>
", "git -C <directory> ...
" tells Git to go there before doing anything else.
See commit 44e1e4 by Nazri Ramliy:
It takes more keypresses to invoke Git command in a different directory without leaving the current directory:
(cd ~/foo && git status)
git --git-dir=~/foo/.git --work-tree=~/foo status
GIT_DIR=~/foo/.git GIT_WORK_TREE=~/foo git status(cd ../..; git grep foo)
for d in d1 d2 d3; do (cd $d && git svn rebase); done
The methods shown above are acceptable for scripting but are too cumbersome for quick command line invocations.
With this new option, the above can be done with fewer keystrokes:
git -C ~/foo status
git -C ../.. grep foo
for d in d1 d2 d3; do git -C $d svn rebase; done
Since Git 2.3.4 (March 2015), and commit 6a536e2 by Karthik Nayak (KarthikNayak
), git
will treat "git -C '<path>'
" as a no-op when <path>
is empty.
'
git -C ""
' unhelpfully dies with error "Cannot change to ''
", whereas the shell treats cd ""' as a no-op.
Taking the shell's behavior as a precedent, teachgit
to treat -C ""' as a no-op, as well.
4 years later, Git 2.23 (Q3 2019) documents that 'git -C ""
' works and doesn't change directory
It's been behaving so since 6a536e2 (
git
: treat "git -C '<path>'
" as a no-op when<path>
is empty, 2015-03-06, Git v2.3.4).
That means the documentation now (finally) includes:
If '
<path>
' is present but empty, e.g.-C ""
, then the current working directory is left unchanged.
You can see git -C
used with Git 2.26 (Q1 2020), as an example.
See commit b441717, commit 9291e63, commit 5236fce, commit 10812c2, commit 62d58cd, commit b87b02c, commit 9b92070, commit 3595d10, commit f511bc0, commit f6041ab, commit f46c243, commit 99c049b, commit 3738439, commit 7717242, commit b8afb90 (20 Dec 2019) by Denton Liu (Denton-L

: inlinefull_name()
Signed-off-by: Denton Liu
Before, we were running
test_must_fail full_name
. However,test_must_fail
should only be used on git commands.
Inlinefull_name()
so that we can usetest_must_fail
on thegit
command directly.When
full_name()
was introduced in 28fb84382b ("Introduce<branch>@{upstream}
notation", 2009-09-10, Git v1.7.0-rc0 -- merge), thegit -C
option wasn't available yet (since it was introduced in 44e1e4d67d ("git
: run in a directory given with -C option", 2013-09-09, Git v1.8.5-rc0 -- merge listed in batch #5)).
As a result, the helper function removed the need to manuallycd
each time. However, sincegit -C
is available now, we can just use that instead and inlinefull_name()
.

Building upon busylee's answer, this is how you can make a drawable
that only has one unrounded corner (top-left, in this example):
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<solid android:color="@color/white" />
<!-- A numeric value is specified in "radius" for demonstrative purposes only,
it should be @dimen/val_name -->
<corners android:radius="10dp" />
</shape>
</item>
<!-- To keep the TOP-LEFT corner UNROUNDED set both OPPOSITE offsets (bottom+right): -->
<item
android:bottom="10dp"
android:right="10dp">
<shape android:shape="rectangle">
<solid android:color="@color/white" />
</shape>
</item>
</layer-list>
Please note that the above drawable
is not shown correctly in the Android Studio preview (2.0.0p7). To preview it anyway, create another view and use this as android:background="@drawable/..."
.
Had that issue on Ubuntu 14.04, In my case I had also libXtst.so missing:
Could not open library 'libXtst.so': libXtst.so: cannot open shared object
file: No such file or directory
Make sure your symbolic link is pointing to proper file, cd /usr/lib/x86_64-linux-gnu and list libXtst with:
ll |grep libXtst
lrwxrwxrwx 1 root root 16 Oct 7 2016 libXtst.so.6 -> libXtst.so.6.1.0
-rw-r--r-- 1 root root 22880 Aug 16 2013 libXtst.so.6.1.0
Then just create proper symbolic link using:
sudo ln -s libXtst.so.6 libXtst.so
List again:
ll | grep libXtst
lrwxrwxrwx 1 root root 12 Sep 20 10:23 libXtst -> libXtst.so.6
lrwxrwxrwx 1 root root 12 Sep 20 10:23 libXtst.so -> libXtst.so.6
lrwxrwxrwx 1 root root 16 Oct 7 2016 libXtst.so.6 -> libXtst.so.6.1.0
-rw-r--r-- 1 root root 22880 Aug 16 2013 libXtst.so.6.1.0
all set!
You can use the date
function. I'm using strtotime
to get the timestamp to that day ; there are other solutions, like mktime
, for instance.
For instance, with the 'D' modifier, for the textual representation in three letters :
$timestamp = strtotime('2009-10-22');
$day = date('D', $timestamp);
var_dump($day);
You will get :
string 'Thu' (length=3)
And with the 'l' modifier, for the full textual representation :
$day = date('l', $timestamp);
var_dump($day);
You get :
string 'Thursday' (length=8)
Or the 'w' modifier, to get to number of the day (0 to 6, 0 being sunday, and 6 being saturday) :
$day = date('w', $timestamp);
var_dump($day);
You'll obtain :
string '4' (length=1)
I hope following program will solve your problem
String dateStr = "Mon Jun 18 00:00:00 IST 2012";
DateFormat formatter = new SimpleDateFormat("E MMM dd HH:mm:ss Z yyyy");
Date date = (Date)formatter.parse(dateStr);
System.out.println(date);
Calendar cal = Calendar.getInstance();
cal.setTime(date);
String formatedDate = cal.get(Calendar.DATE) + "/" + (cal.get(Calendar.MONTH) + 1) + "/" + cal.get(Calendar.YEAR);
System.out.println("formatedDate : " + formatedDate);
SimpleDateFormat sdf=new SimpleDateFormat("EEE");
EEE stands for day of week for example Thursday is displayed as Thu.
I had the same issue and I resolved it with MySQL workbench, as shown in the attached screenshot:
Hope that helps!
In PowerShell 3, $PsScriptRoot
or for your question of two parents up,
$dir = ls "$PsScriptRoot\..\.."
Use %p
, for "pointer", and don't use anything else*. You aren't guaranteed by the standard that you are allowed to treat a pointer like any particular type of integer, so you'd actually get undefined behaviour with the integral formats. (For instance, %u
expects an unsigned int
, but what if void*
has a different size or alignment requirement than unsigned int
?)
*) [See Jonathan's fine answer!] Alternatively to %p
, you can use pointer-specific macros from <inttypes.h>
, added in C99.
All object pointers are implicitly convertible to void*
in C, but in order to pass the pointer as a variadic argument, you have to cast it explicitly (since arbitrary object pointers are only convertible, but not identical to void pointers):
printf("x lives at %p.\n", (void*)&x);
You need an scp client. Putty is not one. You can use WinSCP or PSCP. Both are free software.
sometimes you need to select some fields by FirstOrDefault()
or singleOrDefault()
you can use the below query:
List<ResultLine> result = Lines
.GroupBy(l => l.ProductCode)
.Select(cl => new Models.ResultLine
{
ProductName = cl.select(x=>x.Name).FirstOrDefault(),
Quantity = cl.Count().ToString(),
Price = cl.Sum(c => c.Price).ToString(),
}).ToList();
Once you have the source trees, e.g.
diff -ENwbur repos1/ repos2/
Even better
diff -ENwbur repos1/ repos2/ | kompare -o -
and have a crack at it in a good gui tool :)
Note Wording changed in response to the commments. Thanks @slekse
That is not an error, it is a warning. It means the branch you are about to delete contains commits that are not reachable from any of: its upstream branch, or HEAD (currently checked out revision). In other words, when you might lose commits¹.
In practice it means that you probably amended, rebased or filtered commits and they don't seem identical.
Therefore you could avoid the warning by checking out a branch that does contain the commits that you're about un-reference by deleting that other branch.²
You will want to verify that you in fact aren't missing any vital commits:
git log --graph --left-right --cherry-pick --oneline master...experiment
This will give you a list of any nonshared between the branches. In case you are curious, there might be a difference without --cherry-pick
and this difference could well be the reason for the warning you get:
--cherry-pick
Omit any commit that introduces the same change as another commit on the "other side" when the set of commits are limited with symmetric difference. For example, if you have two branches, A and B, a usual way to list all commits on only one side of them is with --left-right, like the example above in the description of that option. It however shows the commits that were cherry-picked from the other branch (for example, "3rd on b" may be cherry-picked from branch A). With this option, such pairs of commits are excluded from the output.
¹ they're really only garbage collected after a while, by default. Also, the git-branch
command does not check the revision tree of all branches. The warning is there to avoid obvious mistakes.
² (My preference here is to just force the deletion instead, but you might want to have the extra reassurance).
Well, ["Title", "Ramones"]
is an array of strings. But [{"01":"Title", "02", "Ramones"}]
is an array of object.
If you are willing to push properties or value into one object, you need to access that object and then push data into that.
Example:
nietos[indexNumber].yourProperty=yourValue;
in real application:
nietos[0].02 = "Ramones";
If your array of object is already empty, make sure it has at least one object, or that object in which you are going to push data to.
Let's say, our array is myArray[]
, so this is now empty array, the JS engine does not know what type of data does it have, not string, not object, not number nothing. So, we are going to push an object (maybe empty object) into that array. myArray.push({})
, or myArray.push({""})
.
This will push an empty object into myArray
which will have an index number 0
, so your exact object is now myArray[0]
Then push property
and value
into that like this:
myArray[0].property = value;
//in your case:
myArray[0]["01"] = "value";
index
and find
Next to the find
method there is as well index
. find
and index
both yield the same result: returning the position of the first occurrence, but if nothing is found index
will raise a ValueError
whereas find
returns -1
. Speedwise, both have the same benchmark results.
s.find(t) #returns: -1, or index where t starts in s
s.index(t) #returns: Same as find, but raises ValueError if t is not in s
rfind
and rindex
:In general, find and index return the smallest index where the passed-in string starts, and
rfind
andrindex
return the largest index where it starts Most of the string searching algorithms search from left to right, so functions starting withr
indicate that the search happens from right to left.
So in case that the likelihood of the element you are searching is close to the end than to the start of the list, rfind
or rindex
would be faster.
s.rfind(t) #returns: Same as find, but searched right to left
s.rindex(t) #returns: Same as index, but searches right to left

There is no need to create a Java project and let unnecessary Java dependencies and libraries to cling into the project. The question is regarding importing an existing directory into eclipse
Suppose the directory is present in C:/harley/mydir. What you have to do is the following:
Create a new project (Right click on Project explorer, select New -> Project; from the wizard list, select General -> Project and click next.)
Give to the project the same name of your target directory (in this case mydir)
Uncheck Use default location and give the exact location, for example C:/harley/mydir
Click on Finish
You are done. I do it this way.
I faced the same issue when I had to pass a pom version to a downstream Rundeck job.
What I did, was using parameters injection via a properties file as such:
1) Creating properties in properties file via shell :
Build actions:
E.g : properties definition
2) Passing defined properties to the downstream job : Post Build Actions :
E.g : properties sending
3) It was then possible to use $POM_VERSION as such in the downstream Rundeck job.
/!\ Jenkins Version : 1.636
/!\ For some reason when creating the triggered build, it was necessary to add the option 'Current build parameters' to pass the properties.
The self
keyword in Python is analogous to this
keyword in C++ / Java / C#.
In Python 2 it is done implicitly by the compiler (yes Python does compilation internally). It's just that in Python 3 you need to mention it explicitly in the constructor and member functions. example:
class Pump():
//member variable
account_holder
balance_amount
// constructor
def __init__(self,ah,bal):
| self.account_holder = ah
| self.balance_amount = bal
def getPumps(self):
| print("The details of your account are:"+self.account_number + self.balance_amount)
//object = class(*passing values to constructor*)
p = Pump("Tahir",12000)
p.getPumps()
way too old question but I didn't see this answer anywhere...
Check this link:

Fortunately there is a plugin called "AllowClipboardHelper" which makes things easier with only a few clicks. however you still need to instruct your website's visitors on how to enable the access in firefox.
Using Android default libraries like AppCompat, you can convert all the PDF pages into images. This way is very fast and optimized. The below code is for getting separate images of a PDF page. It is very fast and quick.
ParcelFileDescriptor fileDescriptor = ParcelFileDescriptor.open(new File("pdfFilePath.pdf"), MODE_READ_ONLY);
PdfRenderer renderer = new PdfRenderer(fileDescriptor);
final int pageCount = renderer.getPageCount();
for (int i = 0; i < pageCount; i++) {
PdfRenderer.Page page = renderer.openPage(i);
Bitmap bitmap = Bitmap.createBitmap(page.getWidth(), page.getHeight(),Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
canvas.drawColor(Color.WHITE);
canvas.drawBitmap(bitmap, 0, 0, null);
page.render(bitmap, null, null, PdfRenderer.Page.RENDER_MODE_FOR_DISPLAY);
page.close();
if (bitmap == null)
return null;
if (bitmapIsBlankOrWhite(bitmap))
return null;
String root = Environment.getExternalStorageDirectory().toString();
File file = new File(root + filename + ".png");
if (file.exists()) file.delete();
try {
FileOutputStream out = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
Log.v("Saved Image - ", file.getAbsolutePath());
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
=======================================================
private static boolean bitmapIsBlankOrWhite(Bitmap bitmap) {
if (bitmap == null)
return true;
int w = bitmap.getWidth();
int h = bitmap.getHeight();
for (int i = 0; i < w; i++) {
for (int j = 0; j < h; j++) {
int pixel = bitmap.getPixel(i, j);
if (pixel != Color.WHITE) {
return false;
}
}
}
return true;
}
Optional should mainly be used for results of Services anyway. In the service you know what you have at hand and return Optional.of(someValue) if you have a result and return Optional.empty() if you don't. In this case, someValue should never be null and still, you return an Optional.
This can be changed to 0/1 through using CASE WHEN
like this example:
SELECT
CASE WHEN SchemaName.TableName.BitFieldName = 'true' THEN 1 ELSE 0 END AS 'bit Value'
FROM SchemaName.TableName

Unlike accepted answer, I use usermod
instead.
Assume already logged-in as root in docker, and "fruit" is the new non-root username I want to add, simply run this commands:
apt update && apt install sudo
adduser fruit
usermod -aG sudo fruit
Remember to save image after update. Use docker ps
to get current running docker's <CONTAINER ID> and <IMAGE>, then run docker commit -m "added sudo user" <CONTAINER ID> <IMAGE>
to save docker image.
Then test with:
su fruit
sudo whoami
Or test by direct login(ensure save image first) as that non-root user when launch docker:
docker run -it --user fruit <IMAGE>
sudo whoami
You can use sudo -k
to reset password prompt timestamp:
sudo whoami # No password prompt
sudo -k # Invalidates the user's cached credentials
sudo whoami # This will prompt for password
I implemented a function similar to the momentjs method subtract.
function addDate(dt, amount, dateType) {
switch (dateType) {
case 'days':
return dt.setDate(dt.getDate() + amount) && dt;
case 'weeks':
return dt.setDate(dt.getDate() + (7 * amount)) && dt;
case 'months':
return dt.setMonth(dt.getMonth() + amount) && dt;
case 'years':
return dt.setFullYear( dt.getFullYear() + amount) && dt;
}
}
example:
let dt = new Date();
dt = addDate(dt, -1, 'months');// use -1 to subtract
export enum dateAmountType {
DAYS,
WEEKS,
MONTHS,
YEARS,
}
export function addDate(dt: Date, amount: number, dateType: dateAmountType): Date {
switch (dateType) {
case dateAmountType.DAYS:
return dt.setDate(dt.getDate() + amount) && dt;
case dateAmountType.WEEKS:
return dt.setDate(dt.getDate() + (7 * amount)) && dt;
case dateAmountType.MONTHS:
return dt.setMonth(dt.getMonth() + amount) && dt;
case dateAmountType.YEARS:
return dt.setFullYear( dt.getFullYear() + amount) && dt;
}
}
example:
let dt = new Date();
dt = addDate(dt, -1, 'months'); // use -1 to subtract
I also made some unit-tests for this function using Jasmine:
it('addDate() should works properly', () => {
for (const test of [
{ amount: 1, dateType: dateAmountType.DAYS, expect: '2020-04-13'},
{ amount: -1, dateType: dateAmountType.DAYS, expect: '2020-04-11'},
{ amount: 1, dateType: dateAmountType.WEEKS, expect: '2020-04-19'},
{ amount: -1, dateType: dateAmountType.WEEKS, expect: '2020-04-05'},
{ amount: 1, dateType: dateAmountType.MONTHS, expect: '2020-05-12'},
{ amount: -1, dateType: dateAmountType.MONTHS, expect: '2020-03-12'},
{ amount: 1, dateType: dateAmountType.YEARS, expect: '2021-04-12'},
{ amount: -1, dateType: dateAmountType.YEARS, expect: '2019-04-12'},
]) {
expect(formatDate(addDate(new Date('2020-04-12'), test.amount, test.dateType))).toBe(test.expect);
}
});
To use this test you need this function:
// get format date as 'YYYY-MM-DD'
export function formatDate(date: Date): string {
const d = new Date(date);
let month = '' + (d.getMonth() + 1);
let day = '' + d.getDate();
const year = d.getFullYear();
if (month.length < 2) {
month = '0' + month;
}
if (day.length < 2) {
day = '0' + day;
}
return [year, month, day].join('-');
}
If you want a clean design without codes, use:
<CheckBox
android:id="@+id/checkBox1"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:drawableLeft="@android:color/transparent"
android:drawablePadding="10dp"
android:text="CheckBox"/>
The trick is to set colour to transparent for android:drawableLeft
and assign a value for android:drawablePadding
. Also, transparency allows you to use this technique on any background colour without the side effect - like colour mismatch.
Using Java 8 parallelStream would be faster. Below is my code for finding Nth prime number
public static Integer findNthPrimeNumber(Integer nthNumber) {
List<Integer> primeList = new ArrayList<>();
primeList.addAll(Arrays.asList(2, 3));
Integer initializer = 4;
while (primeList.size() < nthNumber) {
if (isPrime(initializer, primeList)) {
primeList.add(initializer);
}
initializer++;
}
return primeList.get(primeList.size() - 1);
}
public static Boolean isPrime(Integer input, List<Integer> primeList) {
return !(primeList.parallelStream().anyMatch(i -> input % i == 0));
}
@Test
public void findNthPrimeTest() {
Problem7 inputObj = new Problem7();
Integer methodOutput = inputObj.findNthPrimeNumber(100);
Assert.assertEquals((Integer) 541, methodOutput);
Assert.assertEquals((Integer) 104743, inputObj.findNthPrimeNumber(10001));
}
How about:
df['D'] = df['B'].values
I don't have PHP experience, but I have an understanding of the Python standard library.
For your purposes, Python has several methods:
logging module;
Object serialization module which is called pickle. You may write your own wrapper of the pickle module.
If your using var_dump
for testing, Python has its own doctest and unittest modules. It's very simple and fast for design.
Math.floor(1+7/8)
Per the developers, this error is not an actual failure, but rather "misleading error reports". This bug is fixed in version 40, which is available on the canary and dev channels as of 25 Oct.
This worked for me
PHP 7.2
AddHandler application/x-httpd-ea-php72 .php .php7 .phtml
PHP 7.3
AddHandler application/x-httpd-ea-php73 .php
Cloud 9 IDE. Storage is cloud+local, it offers autocompletion, it provides explicit support for node.js development, offers real-time collaboration, and you get bash into the deal with all its most popular tools (gcc included). All without having to open anything other than your browser.
I think that's Pretty Awesome.
EDIT Q3 2013 I would also suggest JetBrains WebStorm. It has autocompletion and solid refactoring features for HTML5, CSS3, JS. And it is very responsive.
it also happens when you call a function from jsx directly rather than in an event. like
it will show the error if you write like
<h1>{this.myFunc}<h2>
it will go if you write:
<h1 onClick={this.myFunc}>Hit Me</h1>
To run https functionality or SSL authentication in flask application you first install "pyOpenSSL" python package using:
pip install pyopenssl
Next step is to create 'cert.pem' and 'key.pem' using following command on terminal :
openssl req -x509 -newkey rsa:4096 -nodes -out cert.pem -keyout key.pem -days 365
Copy generated 'cert.pem' and 'kem.pem' in you flask application project
Add ssl_context=('cert.pem', 'key.pem') in app.run()
For example:
from flask import Flask, jsonify
app = Flask(__name__)
@app.route('/')
def index():
return 'Flask is running!'
@app.route('/data')
def names():
data = {"names": ["John", "Jacob", "Julie", "Jennifer"]}
return jsonify(data)
if __name__ == '__main__':
app.run(ssl_context=('cert.pem', 'key.pem'))
This often occurs when you build software in RHEL 7 and try to run on RHEL 6.
To update GLIBC to any version, simply download the package from
For example glibc-2.14.tar.gz in your case.
1. tar xvfz glibc-2.14.tar.gz
2. cd glibc-2.14
3. mkdir build
4. cd build
5. ../configure --prefix=/opt/glibc-2.14
6. make
7. sudo make install
8. export LD_LIBRARY_PATH=/opt/glibc-2.14/lib:$LD_LIBRARY_PATH
Then try to run your software, glibc-2.14 should be linked.
Your setup.py
file needs setuptools
. Some Python packages used to use distutils
for distribution, but most now use setuptools
, a more complete package. Here is a question about the differences between them.
To install setuptools
on Debian:
sudo apt-get install python3-setuptools
For an older version of Python (Python 2.x):
sudo apt-get install python-setuptools
you can use awk
:
kubectl get pods --all-namespaces | awk '{if ($4=="Terminating") print "oc delete pod " $2 " -n " $1 " --force --grace-period=0 ";}' | sh
yes, by the concept of pointer you can do it like this for an int variable:
int *a;
int b=0;
a=NULL; // or a=&b; for giving the value of b to a
if(a==NULL)
printf("NULL");
else
printf(*a);
it is very simple and straitforward. it worked for me in Arduino IDE.
I'm not exactly sure what it is that you want. Do you want a TimeStamp? Then you can do something simple like:
TimeStamp ts = TimeStamp.FromTicks(value.ToUniversalTime().Ticks);
Since you named a variable epoch, do you want the Unix time equivalent of your date?
DateTime unixStart = DateTime.SpecifyKind(new DateTime(1970, 1, 1), DateTimeKind.Utc);
long epoch = (long)Math.Floor((value.ToUniversalTime() - unixStart).TotalSeconds);
Simply Use This
.table-responsive {
overflow: inherit;
}
It works on Chrome, but not IE10 or Edge because inherit property is not supported
componentWillUnmount
setState
,Answering my own question here... turns out it's a Windows only quirk that happens when reading binary files (in my case a JPEG) that requires an additional flag in the open or File.open function call. I revised it to open("/path/to/file", 'rb') {|io| a = a + io.read}
and all was fine.
This works:
assertThat(list,IsEmptyCollection.empty())
netstat -ano|grep 443|grep LISTEN
will tell you whether a process is listening on port 443 (you might have to replace LISTEN with a string in your language, though, depending on your system settings).
Summary
Note, I'm presuming PyMongo, change to suit your language of choice.
Instructions:
Create the collection with an index with unique=true so you don't get duplicate records.
Iterate over your input records, creating batches of them of 15,000 records or so. For each record in the batch, create a dict consisting of the data you want to insert, presuming each one is going to be a new record. Add the 'created' and 'updated' timestamps to these. Issue this as a batch insert command with the 'ContinueOnError' flag=true, so the insert of everything else happens even if there's a duplicate key in there (which it sounds like there will be). THIS WILL HAPPEN VERY FAST. Bulk inserts rock, I've gotten 15k/second performance levels. Further notes on ContinueOnError, see http://docs.mongodb.org/manual/core/write-operations/
Record inserts happen VERY fast, so you'll be done with those inserts in no time. Now, it's time to update the relevant records. Do this with a batch retrieval, much faster than one at a time.
Iterate over all your input records again, creating batches of 15K or so. Extract out the keys (best if there's one key, but can't be helped if there isn't). Retrieve this bunch of records from Mongo with a db.collectionNameBlah.find({ field : { $in : [ 1, 2,3 ...}) query. For each of these records, determine if there's an update, and if so, issue the update, including updating the 'updated' timestamp.
Unfortunately, we should note, MongoDB 2.4 and below do NOT include a bulk update operation. They're working on that.
Key Optimization Points:
A break will allow you continue processing in the function. Just returning out of the switch is fine if that's all you want to do in the function.
rmdir /s /q folder
powershell -Command "Remove-Item -LiteralPath 'folder' -Force -Recurse"
Note that in more cases del
and rmdir
wil leave you with leftover files, where Powershell manages to delete the files.
If you mean that you have an environment variable named CLASSPATH, I'd say that's your mistake. I don't have such a thing on any machine with which I develop Java. CLASSPATH is so tied to a particular project that it's impossible to have a single, correct CLASSPATH that works for all.
I set CLASSPATH for each project using either an IDE or Ant. I do a lot of web development, so each WAR and EAR uses their own CLASSPATH.
It's ignored by IDEs and app servers. Why do you have it? I'd recommend deleting it.
<button class="styleClass" onclick="document.getElementById('getFile').click()">Your text here</button>
<input type='file' id="getFile" style="display:none">
This is still the best so far
setTimeout( function ( ) { alert( "moo" ); }, 10000 ); //displays msg in 10 seconds
I'm not sure if this will work for your actual use, but it works in your test case - updated at http://jsfiddle.net/sTD8y/27/ .
I just made it so that the built-in revert is only used if the item has not been dropped before. If it has been dropped, the revert is done manually. You could adjust this to animate to some calculated offset by checking the actual CSS properties, but I'll let you play with that because a lot of it depends on the CSS of the draggable and it's surrounding DOM structure.
$(function() {
$("#draggable").draggable({
revert: function(dropped) {
var $draggable = $(this),
hasBeenDroppedBefore = $draggable.data('hasBeenDropped'),
wasJustDropped = dropped && dropped[0].id == "droppable";
if(wasJustDropped) {
// don't revert, it's in the droppable
return false;
} else {
if (hasBeenDroppedBefore) {
// don't rely on the built in revert, do it yourself
$draggable.animate({ top: 0, left: 0 }, 'slow');
return false;
} else {
// just let the built in revert work, although really, you could animate to 0,0 here as well
return true;
}
}
}
});
$("#droppable").droppable({
activeClass: 'ui-state-hover',
hoverClass: 'ui-state-active',
drop: function(event, ui) {
$(this).addClass('ui-state-highlight').find('p').html('Dropped!');
$(ui.draggable).data('hasBeenDropped', true);
}
});
});
Pass the arguments to the run
command from within gdb.

Your terminal happens to be configured to UTF-8.
The fact that printing a
works is a coincidence; you are writing raw UTF-8 bytes to the terminal. a
is a value of length two, containing two bytes, hex values C3 and A1, while ua
is a unicode value of length one, containing a codepoint U+00E1.
This difference in length is one major reason to use Unicode values; you cannot easily measure the number of text characters in a byte string; the len()
of a byte string tells you how many bytes were used, not how many characters were encoded.
You can see the difference when you encode the unicode value to different output encodings:
>>> a = 'á'
>>> ua = u'á'
>>> ua.encode('utf8')
'\xc3\xa1'
>>> ua.encode('latin1')
'\xe1'
>>> a
'\xc3\xa1'
Note that the first 256 codepoints of the Unicode standard match the Latin 1 standard, so the U+00E1 codepoint is encoded to Latin 1 as a byte with hex value E1.
Furthermore, Python uses escape codes in representations of unicode and byte strings alike, and low code points that are not printable ASCII are represented using \x..
escape values as well. This is why a Unicode string with a code point between 128 and 255 looks just like the Latin 1 encoding. If you have a unicode string with codepoints beyond U+00FF a different escape sequence, \u....
is used instead, with a four-digit hex value.
It looks like you don't yet fully understand what the difference is between Unicode and an encoding. Please do read the following articles before you continue:
package - takes the compiled code and package it in its distributable format, such as a JAR or WAR file. install - install the package into the local repository, for use as a dependency in other projects locally
I like this if you want to get just some parts of the query:
new CriteriaQueryTranslator(
factory,
executableCriteria,
executableCriteria.getEntityOrClassName(),
CriteriaQueryTranslator.ROOT_SQL_ALIAS)
.getWhereCondition();
For instance something like this:
String where = new CriteriaQueryTranslator(
factory,
executableCriteria,
executableCriteria.getEntityOrClassName(),
CriteriaQueryTranslator.ROOT_SQL_ALIAS)
.getWhereCondition();
String sql = "update my_table this_ set this_.status = 0 where " + where;
also my solution is the boolean label.adjustsFontSizeToFitWidth = YES; BUT. You must in the interface Builder the Word Wrapping switch to "CLIP". Then autoshrink the Labels. This is very important.
I've encountered similar problem on Ubuntu 16.04 and was able to solve it by creating a folder named "default-java" in /usr/lib/jvm
and copying into it all the contents of the /usr/lib/jvm/java-8-oracle
. I opted for this solution as correcting JAVA_HOME environment variable turned out to be of no use.
If it's too late at night and your table is already innoDB and you still don't see the link, maybe is due to the fact that now it's placed above the structure of the table, like in the picture is shown
The fastest solution would be using the regex prototype function test() and looking for any character that is not a space, tab, or line break \S
:
if (!/\S/.test(str)) {
// Didn't find something other than a space which means it's empty
}
In case you have a super long string, it can make a significant difference as it will stop processing as soon as it finds a non-space character.
##Configuring credential.helper
On OS X (now macOS), run this in Terminal:
git config --global credential.helper osxkeychain
It enables Git to use file Keychain.app to store username and password and to retrieve the passphrase to your private SSH key from the keychain.
For Windows use:
git config --global credential.helper wincred
For Linux use:
git config --global credential.helper cache // If you want to cache the credentials for some time (default 15 minutes)
OR
git config --global credential.helper store // if you want to store the credentials for ever (considered unsafe)
Note : The first method will cache the credentials in memory, whereas the second will store them in ~/.git-credentials
in plain text format.
Check here for more info about Linux method.
Check here for more info about all three.
##Troubleshooting
If the Git credential helper is configured correctly macOS saves the passphrase in the keychain. Sometimes the connection between SSH and the passphrases stored in the keychain can break. Run ssh-add -K
or ssh-add ~/.ssh/id_rsa
to add the key to keychain again.
For macOS v10.12 (Sierra), ssh-add -K
needs to be run after every reboot. To avoid this, create ~/.ssh/config
with this content.
Host *
AddKeysToAgent yes
UseKeychain yes
IdentityFile ~/.ssh/id_rsa
From the ssh_config
man
page on 10.12.2:
UseKeychain
On macOS, specifies whether the system should search for passphrases in the user's keychain when attempting to use a particular key. When the passphrase is provided by the user, this option also specifies whether the passphrase should be stored into the keychain once it has been verified to be correct. The argument must be 'yes' or 'no'. The default is 'no'.
Apple has added Technote 2449 which explains what happened.
Prior to macOS Sierra,
ssh
would present a dialog asking for your passphrase and would offer the option to store it into the keychain. This UI was deprecated some time ago and has been removed.
You could add to a set
until you reach n
:
setOfNumbers = set()
while len(setOfNumbers) < n:
setOfNumbers.add(random.randint(numLow, numHigh))
Be careful of having a smaller range than will fit in n
. It will loop forever, unable to find new numbers to insert up to n
You can’t run arbitrary Python code in jinja; it doesn’t work like JSP in that regard (it just looks similar). All the things in jinja are custom syntax.
For your purpose, it would make most sense to define a custom filter, so you could for example do the following:
The grass is {{ variable1 | splitpart(0, ',') }} and the boat is {{ splitpart(1, ',') }}
Or just:
The grass is {{ variable1 | splitpart(0) }} and the boat is {{ splitpart(1) }}
The filter function could then look like this:
def splitpart (value, index, char = ','):
return value.split(char)[index]
An alternative, which might make even more sense, would be to split it in the controller and pass the splitted list to the view.
Notice you're not dynamically allocating the variable, which pretty much means the data inside str
, in your function, will be lost by the end of the function.
You should have:
char * createStr() {
char char1= 'm';
char char2= 'y';
char *str = malloc(3);
str[0] = char1;
str[1] = char2;
str[2] = '\0';
return str;
}
Then, when you call the function, the type of the variable that will receive the data must match that of the function return. So, you should have:
char *returned_str = createStr();
It worths mentioning that the returned value must be freed to prevent memory leaks.
char *returned_str = createStr();
//doSomething
...
free(returned_str);
Are they in the right subdirectories?
If you put /usr/share/stuff
on the class path, files defined with package org.name
should be in /usr/share/stuff/org/name
.
EDIT: If you don't already know this, you should probably read this: http://download.oracle.com/javase/1.5.0/docs/tooldocs/windows/classpath.html#Understanding
EDIT 2: Sorry, I hadn't realised you were talking of Java source files in /usr/share/stuff
. Not only they need to be in the appropriate sub-directory, but you need to compile them. The .java
files don't need to be on the classpath, but on the source path. (The generated .class
files need to be on the classpath.)
You might get away with compiling them if they're not under the right directory structure, but they should be, or it will generate warnings at least. The generated class files will be in the right subdirectories (wherever you've specified -d
if you have).
You should use something like javac -sourcepath .:/usr/share/stuff test.java
, assuming you've put the .java
files that were under /usr/share/stuff
under /usr/share/stuff/org/name
(or whatever is appropriate according to their package names).
ptomato's code can also be written in a cleaner manner like:
ifeq ($(TARGET_CPU),x86) TARGET_CPU_IS_X86 := 1 else ifeq ($(TARGET_CPU),x86_64) TARGET_CPU_IS_X86 := 1 else TARGET_CPU_IS_X86 := 0 endif
This doesn't answer OP's question but as it's the top result on google, I'm adding it here in case it's useful to anyone else.
A couple of scenarios might help illustrate the purpose of access and refresh tokens and the engineering trade-offs in designing an oauth2 (or any other auth) system:
In the web app scenario you have a couple of options:
Let's imagine that someone manages to hijack your session. The only thing that is possible is to request your pages.
Comparing 1 and 2:
In 1, access_token and refresh_token only travel over the wire on the way between the authorzation server (google in your case) and your app server. This would be done on a secure channel. A hacker could hijack the session but they would only be able to interact with your web app. In 2, the hacker could take the access_token away and form their own requests to the resources that the user has granted access to. Even if the hacker gets a hold of the access_token they will only have a short window in which they can access the resources.
Either way the refresh_token and clientid/secret are only known to the server making it impossible from the web browser to obtain long term access.
Let's imagine you are implementing oauth2 and set a long timeout on the access token:
In 1) There's not much difference here between a short and long access token since it's hidden in the app server. In 2) someone could get the access_token in the browser and then use it to directly access the user's resources for a long time.
On the mobile, there are a couple of scenarios that I know of:
Store clientid/secret on the device and have the device orchestrate obtaining access to the user's resources.
Use a backend app server to hold the clientid/secret and have it do the orchestration. Use the access_token as a kind of session key and pass it between the client and the app server.
Comparing 1 and 2
In 1) Once you have clientid/secret on the device they aren't secret any more. Anyone can decompile and then start acting as though they are you, with the permission of the user of course. The access_token and refresh_token are also in memory and could be accessed on a compromised device which means someone could act as your app without the user giving their credentials. In this scenario the length of the access_token makes no difference to the hackability since refresh_token is in the same place as access_token. In 2) the clientid/secret nor the refresh token are compromised. Here the length of the access_token expiry determines how long a hacker could access the users resources, should they get hold of it.
Here it depends upon what you're securing with your auth system as to how long your access_token expiry should be. If it's something particularly valuable to the user it should be short. Something less valuable, it can be longer.
Some people like google don't expire the refresh_token. Some like stackflow do. The decision on the expiry is a trade-off between user ease and security. The length of the refresh token is related to the user return length, i.e. set the refresh to how often the user returns to your app. If the refresh token doesn't expire the only way they are revoked is with an explicit revoke. Normally, a log on wouldn't revoke.
Hope that rather length post is useful.
I would suggest adding
(?!.*pass|.*word|.*1234|.*qwer|.*asdf) exclude common passwords
There is no log file. Each node.js "app" is a separate entity. By default it will log errors to STDERR and output to STDOUT. You can change that when you run it from your shell to log to a file instead.
node my_app.js > my_app_log.log 2> my_app_err.log
Alternatively (recommended), you can add logging inside your application either manually or with one of the many log libraries:
if all you need is the names, use xpath instead. No need to do the iteration yourself and check for null.
string xml = @"
<root>
<Employee name=""an"" />
<Employee name=""nobyd"" />
<Employee/>
</root>
";
var doc = new XmlDocument();
//doc.Load(path);
doc.LoadXml(xml);
var names = doc.SelectNodes("//Employee/@name");
Two entries in an array can't share a key, you'll need to change the key for the duplicate
as above, but qualitatively:
private - least access, best encapsulation
protected - some access, moderate encapsulation
public - full access, no encapsulation
the less access you provide the fewer implementation details leak out of your objects. less of this sort of leakage means more flexibility (aka "looser coupling") in terms of changing how an object is implemented without breaking clients of the object. this is a truly fundamental thing to understand.
As Paul stated, it's because 'a'
is an int
in C but a char
in C++.
I cover that specific difference between C and C++ in something I wrote a few years ago, at: http://david.tribble.com/text/cdiffs.htm
This is a variable jQuery uses internally, but had no reason to hide, so it's there to use. Just a heads up, it becomes jquery.ajax.active
next release. There's no documentation because it's exposed but not in the official API, lots of things are like this actually, like jQuery.cache
(where all of jQuery.data()
goes).
I'm guessing here by actual usage in the library, it seems to be there exclusively to support $.ajaxStart()
and $.ajaxStop()
(which I'll explain further), but they only care if it's 0 or not when a request starts or stops. But, since there's no reason to hide it, it's exposed to you can see the actual number of simultaneous AJAX requests currently going on.
When jQuery starts an AJAX request, this happens:
if ( s.global && ! jQuery.active++ ) {
jQuery.event.trigger( "ajaxStart" );
}
This is what causes the $.ajaxStart()
event to fire, the number of connections just went from 0 to 1 (jQuery.active++
isn't 0 after this one, and !0 == true
), this means the first of the current simultaneous requests started. The same thing happens at the other end. When an AJAX request stops (because of a beforeSend
abort via return false
or an ajax call complete
function runs):
if ( s.global && ! --jQuery.active ) {
jQuery.event.trigger( "ajaxStop" );
}
This is what causes the $.ajaxStop()
event to fire, the number of requests went down to 0, meaning the last simultaneous AJAX call finished. The other global AJAX handlers fire in there along the way as well.
What worked for me is using sys.path.insert
. Then I specified the directory I needed to go. For example I just needed to go up one directory.
import sys
sys.path.insert(0, '../')
I did this:
var dateToday = new Date();
var yrRange = dateToday.getFullYear() + ":" + (dateToday.getFullYear() + 50);
and then
yearRange : yrRange
where 50
is the range from current year.
Your server tells you exactly what you need : [Hint: SSLProxyEngine]
You need to add that directive to your VirtualHost
before the Proxy
directives :
SSLProxyEngine on
ProxyPass /primary/store https://localhost:9763/store/
ProxyPassReverse /primary/store https://localhost:9763/store/
For those of you who would like to simulate the set_contents_from_string
like boto2 methods, you can try
import boto3
from cStringIO import StringIO
s3c = boto3.client('s3')
contents = 'My string to save to S3 object'
target_bucket = 'hello-world.by.vor'
target_file = 'data/hello.txt'
fake_handle = StringIO(contents)
# notice if you do fake_handle.read() it reads like a file handle
s3c.put_object(Bucket=target_bucket, Key=target_file, Body=fake_handle.read())
For Python3:
In python3 both StringIO and cStringIO are gone. Use the StringIO
import like:
from io import StringIO
To support both version:
try:
from StringIO import StringIO
except ImportError:
from io import StringIO
The other answers are generally correct and all outdated. Do use java.time, the modern Java date and time API, for your date and time work. With java.time your job has also become a lot easier compared to the situation when this question was asked in February 2014.
String dateTimeString = "2014-01-16T10:25:00";
LocalDateTime dateTime = LocalDateTime.parse(dateTimeString);
LocalDateTime now = LocalDateTime.now(ZoneId.systemDefault());
if (dateTime.isBefore(now)) {
System.out.println(dateTimeString + " is in the past");
} else if (dateTime.isAfter(now)) {
System.out.println(dateTimeString + " is in the future");
} else {
System.out.println(dateTimeString + " is now");
}
When running in 2020 output from this snippet is:
2014-01-16T10:25:00 is in the past
Since your string doesn’t inform of us any time zone or UTC offset, we need to know what was understood. The code above uses the device’ time zone setting. For a known time zone use like for example ZoneId.of("Asia/Ulaanbaatar")
. For UTC specify ZoneOffset.UTC

I am exploiting the fact that your string is in ISO 8601 format. The classes of java.time parse the most common ISO 8601 variants without us having to give any formatter.
java.time works nicely on both older and newer Android devices. It just requires at least Java 6.
org.threeten.bp
with subpackages.java.time
was first described.java.time
to Java 6 and 7 (ThreeTen for JSR-310).For using another docker-compose network you just do these(to share networks between docker-compose):
- Run the first docker-compose project by
up -d
- Find the network name of the first docker-compose by:
docker network ls
(It contains the name of the root directory project)- Then use that name by this structure at below in the second docker-compose file.
second docker-compose.yml
version: '3'
services:
service-on-second-compose: # Define any names that you want.
.
.
.
networks:
- <put it here(the network name that comes from "docker network ls")>
networks:
- <put it here(the network name that comes from "docker network ls")>:
external: true
I Faced the same issue while installing a setup using a jar file. Solution thta worked for me is
java -jar <<jar fully qualified path>>
It worked for me :)
In my case, the page needed to close, but may have been opened by a link and thus window.close
would fail.
The solution I chose is to issue the window.close
, followed by a window.setTimeout
that redirects to a different page.
That way, if window.close
succeeds, execution on that page stops, but if it fails, in a second, it will redirect to a different page.
window.close();
window.setTimeout(function(){location.href = '/some-page.php';},1000);
How about writing your own concat method?
public static Stream<T> concat(Stream<? extends T> a,
Stream<? extends T> b,
Stream<? extends T> args)
{
Stream<T> concatenated = Stream.concat(a, b);
for (Stream<T> stream : args)
{
concatenated = Stream.concat(concatenated, stream);
}
return concatenated;
}
This at least makes your first example a lot more readable.
var request = require('request');
function updateClient(postData){
var clientServerOptions = {
uri: 'http://'+clientHost+''+clientContext,
body: JSON.stringify(postData),
method: 'POST',
headers: {
'Content-Type': 'application/json'
}
}
request(clientServerOptions, function (error, response) {
console.log(error,response.body);
return;
});
}
For this to work, your server must be something like:
var express = require('express');
var bodyParser = require('body-parser');
var app = express();
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json())
var port = 9000;
app.post('/sample/put/data', function(req, res) {
console.log('receiving data ...');
console.log('body is ',req.body);
res.send(req.body);
});
// start the server
app.listen(port);
console.log('Server started! At http://localhost:' + port);
The javax.mail-api
artifact is only good for compiling against.
You actually need to run code, so you need a complete implementation of JavaMail API. Use this:
<dependency>
<groupId>com.sun.mail</groupId>
<artifactId>javax.mail</artifactId>
<version>1.6.2</version>
</dependency>
NOTE: The version number will probably differ. Check the latest version here.
First, a clarification, Java is not fully static-compiled and linked in the way C++. It is compiled into bytecode, which is then interpreted by a JVM. The JVM can go and do just-in-time compilation to the native machine language, but doesn't have to do it.
More to the point: I think interactivity is the main practical difference. Since everything is interpreted, you can take a small excerpt of code, parse and run it against the current state of the environment. Thus, if you had already executed code that initialized a variable, you would have access to that variable, etc. It really lends itself way to things like the functional style.
Interpretation, however, costs a lot, especially when you have a large system with a lot of references and context. By definition, it is wasteful because identical code may have to be interpreted and optimized twice (although most runtimes have some caching and optimizations for that). Still, you pay a runtime cost and often need a runtime environment. You are also less likely to see complex interprocedural optimizations because at present their performance is not sufficiently interactive.
Therefore, for large systems that are not going to change much, and for certain languages, it makes more sense to precompile and prelink everything, do all the optimizations that you can do. This ends up with a very lean runtime that is already optimized for the target machine.
As for generating executables, that has little to do with it, IMHO. You can often create an executable from a compiled language. But you can also create an executable from an interpreted language, except that the interpreter and runtime is already packaged in the exectuable and hidden from you. This means that you generally still pay the runtime costs (although I am sure that for some language there are ways to translate everything to a tree executable).
I disagree that all languages could be made interactive. Certain languages, like C, are so tied to the machine and the entire link structure that I'm not sure you can build a meaningful fully-fledged interactive version
Take away the spaces. So do:
matches <- unique(grep("A1|A9|A6", myfile$Letter, value=TRUE, fixed=TRUE))
See Creating a shared and static library with the gnu compiler [gcc]
gcc -c -o out.o out.c
-c
means to create an intermediary object file, rather than an executable.
ar rcs libout.a out.o
This creates the static library. r
means to insert with replacement, c
means to create a new archive, and s
means to write an index. As always, see the man page for more info.
Here's what I use. If you just subtract the dates, it won't work across the Daylight Savings Time Boundary (eg April 1 to April 30 or Oct 1 to Oct 31). This drops all the hours to make sure you get a day and eliminates any DST problem by using UTC.
var nDays = ( Date.UTC(EndDate.getFullYear(), EndDate.getMonth(), EndDate.getDate()) -
Date.UTC(StartDate.getFullYear(), StartDate.getMonth(), StartDate.getDate())) / 86400000;
as a function:
function DaysBetween(StartDate, EndDate) {
// The number of milliseconds in all UTC days (no DST)
const oneDay = 1000 * 60 * 60 * 24;
// A day in UTC always lasts 24 hours (unlike in other time formats)
const start = Date.UTC(EndDate.getFullYear(), EndDate.getMonth(), EndDate.getDate());
const end = Date.UTC(StartDate.getFullYear(), StartDate.getMonth(), StartDate.getDate());
// so it's safe to divide by 24 hours
return (start - end) / oneDay;
}
Sounds like you're trying to execute the PHP code directly in your shell. Your shell doesn't speak PHP, so it interprets your PHP code as though it's in your shell's native language, as though you had literally run <?php
at the command line.
Shell scripts usually start with a "shebang" line that tells the shell what program to use to interpret the file. Begin your file like this:
#!/usr/bin/env php
<?php
//Connection
function connection () {
Besides that, the string you're passing to exec
doesn't make any sense. It starts with a slash all by itself, it uses too many periods in the path, and it has a stray right parenthesis.
Copy the contents of the command string and paste them at your command line. If it doesn't run there, then exec
probably won't be able to run it, either.
Another option is to change the command you execute. Instead of running the script directly, run php
and pass your script as an argument. Then you shouldn't need the shebang line.
exec('php name.php');
The remote
section also specifies fetch rules. You could add something like this into it to fetch all branches from the remote:
fetch = +refs/heads/*:refs/remotes/origin/*
(Or replace origin
with bitbucket
.)
Please read about it here: 10.5 Git Internals - The Refspec
If you're using MySQL:
SELECT
DATE(created) AS saledate,
SUM(amount)
FROM
Sales
GROUP BY
saledate
If you're using MS SQL 2008:
SELECT
CAST(created AS date) AS saledate,
SUM(amount)
FROM
Sales
GROUP BY
CAST(created AS date)
Refresh would probably also make for much more readable code, depending on context.
This is more to help people who end up here rather than answer the OP's question:
Try closing and re-opening visual studio, did the trick for me.
Hope this helps someone.
As per the docs select, the following piece of code worked for me.
<div ng-controller="ExampleController">
<form name="myForm">
<label for="mySelect">Make a choice:</label>
<select name="mySelect" id="mySelect"
ng-options="option.name for option in data.availableOptions track by option.id"
ng-model="data.selectedOption"></select>
</form>
<hr>
<tt>option = {{data.selectedOption}}</tt><br/>
</div>
There's no way to guarantee that two functions will execute in sync with each other which seems to be what you want to do.
The best you can do is to split up the function into several steps, then wait for both to finish at critical synchronization points using Process.join
like @aix's answer mentions.
This is better than time.sleep(10)
because you can't guarantee exact timings. With explicitly waiting, you're saying that the functions must be done executing that step before moving to the next, instead of assuming it will be done within 10ms which isn't guaranteed based on what else is going on on the machine.
You can use two for loops in same line by using zip
function
Code:
list1 = ['Abbas', 'Ali', 'Usman']
list2 = ['Kamran', 'Asgar', 'Hamza', 'Umer']
list3 = []
for i,j in zip(list1,list2):
list3.append(i)
list3.append(j)
print(list3)
Output:
['Abbas', 'Kamran', 'Ali', 'Asgar', 'Usman', 'Hamza']
So, by using zip function, we can use two for loops or we can iterate two lists in same row.
You don't say which database you are using but in MS SQL Server it would be
WHERE DateField = {d '2008-12-20'}
If it is a timestamp field then you'll need a range:
WHERE DateField BETWEEN {ts '2008-12-20 00:00:00'} AND {ts '2008-12-20 23:59:59'}
With a recent nightly, you can do this:
let my_int = from_str::<int>(&*my_string);
What's happening here is that String
can now be dereferenced into a str
. However, the function wants an &str
, so we have to borrow again. For reference, I believe this particular pattern (&*
) is called "cross-borrowing".
The Swift version from String to Data and back to String:
Xcode 10.1 • Swift 4.2.1
extension Data {
var string: String? {
return String(data: self, encoding: .utf8)
}
}
extension StringProtocol {
var data: Data {
return Data(utf8)
}
}
extension String {
var base64Decoded: Data? {
return Data(base64Encoded: self)
}
}
Playground
let string = "Hello World" // "Hello World"
let stringData = string.data // 11 bytes
let base64EncodedString = stringData.base64EncodedString() // "SGVsbG8gV29ybGQ="
let stringFromData = stringData.string // "Hello World"
let base64String = "SGVsbG8gV29ybGQ="
if let data = base64String.base64Decoded {
print(data) // 11 bytes
print(data.base64EncodedString()) // "SGVsbG8gV29ybGQ="
print(data.string ?? "nil") // "Hello World"
}
let stringWithAccent = "Olá Mundo" // "Olá Mundo"
print(stringWithAccent.count) // "9"
let stringWithAccentData = stringWithAccent.data // "10 bytes" note: an extra byte for the acute accent
let stringWithAccentFromData = stringWithAccentData.string // "Olá Mundo\n"
If order is not the matter:
>>> foo='mppmt'
>>> ''.join(set(foo))
'pmt'
To keep the order:
>>> foo='mppmt'
>>> ''.join([j for i,j in enumerate(foo) if j not in foo[:i]])
'mpt'
Add #pragma comment(lib, "Your library name here")
to your source.
Try File.basename
Returns the last component of the filename given in file_name, which must be formed using forward slashes (``/’’) regardless of the separator used on the local file system. If suffix is given and present at the end of file_name, it is removed.
File.basename("/home/gumby/work/ruby.rb") #=> "ruby.rb" File.basename("/home/gumby/work/ruby.rb", ".rb") #=> "ruby"
In your case:
File.basename("C:\\projects\\blah.dll", ".dll") #=> "blah"
You can just use Collections.rotate(List<?> list, int distance)
Use Arrays.asList(array)
to convert to List

If you use dialog fragment you can do it on onResume method. It's code for Xamarin Android, but I think it so easy to understand it
public override void OnResume()
{
base.OnResume();
var metrics = Resources.DisplayMetrics;
double width = metrics.WidthPixels * 0.9;
double height = metrics.HeightPixels * 0.6;
this.Dialog.Window.SetLayout((int)width, (int)height);
this.Dialog.Window.SetGravity(Android.Views.GravityFlags.Center);
}
Add Serializable()
before the type you expose
Serializable()
Public Class YourType
Put Serializable
into <>
Building on @Andrew's solution, you'll get much better performance using a non-procedural table-valued-function and CROSS APPLY:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
/* Usage:
SELECT t.[YourColumn], c.StringCount
FROM YourDatabase.dbo.YourTable t
CROSS APPLY dbo.CountOccurrencesOfString('your search string', t.[YourColumn]) c
*/
CREATE FUNCTION [dbo].[CountOccurrencesOfString]
(
@searchTerm nvarchar(max),
@searchString nvarchar(max)
)
RETURNS TABLE
AS
RETURN
SELECT (DATALENGTH(@searchString)-DATALENGTH(REPLACE(@searchString,@searchTerm,'')))/NULLIF(DATALENGTH(@searchTerm), 0) AS StringCount
To adjust the length of the samples:
set key samplen X
(default is 4)
To adjust the vertical spacing of the samples:
set key spacing X
(default is 1.25)
and (for completeness), to adjust the fontsize:
set key font "<face>,<size>"
(default depends on the terminal)
And of course, all these can be combined into one line:
set key samplen 2 spacing .5 font ",8"
Note that you can also change the position of the key using set key at <position>
or any one of the pre-defined positions (which I'll just defer to help key
at this point)
In case anyone else has the same issue as this on
Centos, try:
yum install python-lxml
Ubuntu
sudo apt-get install -y python-lxml
worked for me.
function Index($index) {
$Count = count($YOUR_ARRAY);
if ($index <= $Count) {
$Keys = array_keys($YOUR_ARRAY);
$Value = array_values($YOUR_ARRAY);
return $Keys[$index] . ' = ' . $Value[$index];
} else {
return "Out of the ring";
}
}
echo 'Index : ' . Index(0);
Replace the ( $YOUR_ARRAY )
This is what I like to do:
window.location.search
.substr(1)
.split('&')
.reduce(
function(accumulator, currentValue) {
var pair = currentValue
.split('=')
.map(function(value) {
return decodeURIComponent(value);
});
accumulator[pair[0]] = pair[1];
return accumulator;
},
{}
);
Of course you can make it more compact using modern syntax or writing everything into one line...
I leave that up to you.
WARNING: Security researches have found several poisoned packages on PyPI, including a package named
urllib
, which will 'phone home' when installed. If you usedpip install urllib
some time after June 2017, remove that package as soon as possible.
You can't, and you don't need to.
urllib2
is the name of the library included in Python 2. You can use the urllib.request
library included with Python 3, instead. The urllib.request
library works the same way urllib2
works in Python 2. Because it is already included you don't need to install it.
If you are following a tutorial that tells you to use urllib2
then you'll find you'll run into more issues. Your tutorial was written for Python 2, not Python 3. Find a different tutorial, or install Python 2.7 and continue your tutorial on that version. You'll find urllib2
comes with that version.
Alternatively, install the requests
library for a higher-level and easier to use API. It'll work on both Python 2 and 3.
First make sure that the input element is visible
As stated by Mark Collin in the discussion here:
Don't click on the browse button, it will trigger an OS level dialogue box and effectively stop your test dead.
Instead you can use:
driver.findElement(By.id("myUploadElement")).sendKeys("<absolutePathToMyFile>");
myUploadElement is the id of that element (button in this case) and in sendKeys you have to specify the absolute path of the content you want to upload (Image,video etc). Selenium will do the rest for you.
Keep in mind that the upload will work only If the element you send a file should be in the form <input type="file">
By using document.getElementById()
function you don't have to pass #
before element's id.
Code:
document.getElementById('_1234').checked = true;
Demo: JSFiddle

System.out.println
("Date minus 1 month : "
+ sdf.format(c1.getTime()));
As pointed in Vlad's answer, you are running out of free color slots. One way to get around that would be to cache the colors: whenever you try a RGB combination, the routine should first check if the combination is in the cache; if it is in the cache, then it should use that one instead of creating a new one from scratch; new colors would then only be created if they're not yet in cache.
Here's the implementation I use; it uses XSSF plus Guava's LoadingCache and is geared towards generationg XSSF colors from CSS rgb(r, g, b)
declarations, but it should be relatively trivial to adapt it to HSSF:
private final LoadingCache<String, XSSFColor> colorsFromCSS = CacheBuilder.newBuilder()
.build(new CacheLoader<String, XSSFColor>() {
private final Pattern RGB = Pattern.compile("rgb\\(\\s*(\\d+)\\s*, \\s*(\\d+)\\s*,\\s*(\\d+)\\s*\\)");
@Override
public XSSFColor load(String style) throws Exception {
Matcher mat = RGB.matcher(style);
if (!mat.find()) {
throw new IllegalStateException("Couldn't read CSS color: " + style);
}
return new XSSFColor(new java.awt.Color(
Integer.parseInt(mat.group(1)),
Integer.parseInt(mat.group(2)),
Integer.parseInt(mat.group(3))));
}
});
Perhaps someone else could post a HSSF equivalent? ;)
In recent Oracle versions the COST represent the amount of time that the optimiser expects the query to take, expressed in units of the amount of time required for a single block read.
So if a single block read takes 2ms and the cost is expressed as "250", the query could be expected to take 500ms to complete.
The optimiser calculates the cost based on the estimated number of single block and multiblock reads, and the CPU consumption of the plan. the latter can be very useful in minimising the cost by performing certain operations before others to try and avoid high CPU cost operations.
This raises the question of how the optimiser knows how long operations take. recent Oracle versions allow the collections of "system statistics", which are definitely not to be confused with statistics on tables or indexes. The system statistics are measurements of the performance of the hardware, mostly importantly:
These numbers can vary greatly according to the operating environment of the system, and different sets of statistics can be stored for "daytime OLTP" operations and "nighttime batch reporting" operations, and for "end of month reporting" if you wish.
Given these sets of statistics, a given query execution plan can be evaluated for cost in different operating environments, which might promote use of full table scans at some times or index scans at others.
The cost is not perfect, but the optimiser gets better at self-monitoring with every release, and can feedback the actual cost in comparison to the estimated cost in order to make better decisions for the future. this also makes it rather more difficult to predict.
Note that the cost is not necessarily wall clock time, as parallel query operations consume a total amount of time across multiple threads.
In older versions of Oracle the cost of CPU operations was ignored, and the relative costs of single and multiblock reads were effectively fixed according to init parameters.
I think this may help you solve your issue.
Imagine you have a dictionary like this:
dic0 = {0:"CL1", 1:"CL2", 2:"CL3"}
And you want to change values by this one:
dic0to1 = {"CL1":"Unknown1", "CL2":"Unknown2", "CL3":"Unknown3"}
You can use code bellow to change values of dic0
properly respected to dic0t01
without worrying yourself about indexes in dictionary:
for x, y in dic0.items():
dic0[x] = dic0to1[y]
Now you have:
>>> dic0
{0: 'Unknown1', 1: 'Unknown2', 2: 'Unknown3'}
I love short hands so:

I added the Context Menu item for Folders to open in Sublime Text. In windows, you can right click on any Folder and open the structure in Sublime. You could also create a service (?) for Mac OS - I'm just not familiar with the process.
The following could be saved to a File (OpenFolderWithSublime.reg) to merge to the registry. Be Sure to modify the directory structure to appropriately point to your Sublime installation. Alternatively, you can use REGEDIT and browse to HKCR\Folder\shell and create the values manually.
Windows Registry Editor Version 5.00

You can just read from stdin unless the user supply a filename ?
If not, treat the special "filename" -
as meaning "read from stdin". The user would have to start the program like cat file | myprogram -
if he wants to pipe data to it, and myprogam file
if he wants it to read from a file.
int main(int argc,char *argv[] ) {
FILE *input;
if(argc != 2) {
usage();
return 1;
}
if(!strcmp(argv[1],"-")) {
input = stdin;
} else {
input = fopen(argv[1],"rb");
//check for errors
}
If you're on *nix, you can check whether stdin is a fifo:
struct stat st_info;
if(fstat(0,&st_info) != 0)
//error
}
if(S_ISFIFO(st_info.st_mode)) {
//stdin is a pipe
}
Though that won't handle the user doing myprogram <file
You can also check if stdin is a terminal/console
if(isatty(0)) {
//stdin is a terminal
}
To iterate over each file a for loop will work:
for %%f in (directory\path\*) do ( something_here )
In my case I also wanted the file content, name, etc.
This lead to a few issues and I thought my use case might help. Here is a loop that reads info from each '.txt' file in a directory and allows you do do something with it (setx for instance).
@ECHO OFF
setlocal enabledelayedexpansion
for %%f in (directory\path\*.txt) do (
set /p val=<%%f
echo "fullname: %%f"
echo "name: %%~nf"
echo "contents: !val!"
)
*Limitation: val<=%%f will only get the first line of the file.
check out this link and then help yourself out.
the basic code is
#create a temp. file
echo "hi " > t.tmp
# set the file time to 2 hours ago
touch -t 200405121120 t.tmp
# then check for files
find /admin//dump -type f -newer t.tmp -print -exec ls -lt {} \; | pg
If I understand your question correctly, it appears you want to know the following:
How do I check if my
String
array containsusercode
, theString
that was just inputted?
See here for a similar question. It quotes solutions that have been pointed out by previous answers. I hope this helps.
AFAIK there is no possibility beside from using keys or expect if you are using the command line version ssh
. But there are library bindings for the most programming languages like C, python, php, ... . You could write a program in such a language. This way it would be possible to pass the password automatically. But note this is of course a security problem as the password will be stored in plain text in that program
You can download the latest mysql driver jar from below path, and copy to your classpath or if you are using web server then copy to tomcat/lib or war/web-inf/lib folder.
I was also facing the same problem and solved through making column as nullable using "?" operator.
Sequnce = db.mstquestionbanks.Where(x => x.IsDeleted == false && x.OrignalFormID == OriginalFormIDint).Select(x=><b>(int?)x.Sequence</b>).Max().ToString();
Sometimes null is returned.
You could also achieve the same result by using a Conditional Expression:
maxnum = run if run > value else value
a bit more flexible than max
but admittedly longer to type.
Old style classes are still marginally faster for attribute lookup. This is not usually important, but it may be useful in performance-sensitive Python 2.x code:
In [3]: class A: ...: def __init__(self): ...: self.a = 'hi there' ...: In [4]: class B(object): ...: def __init__(self): ...: self.a = 'hi there' ...: In [6]: aobj = A() In [7]: bobj = B() In [8]: %timeit aobj.a 10000000 loops, best of 3: 78.7 ns per loop In [10]: %timeit bobj.a 10000000 loops, best of 3: 86.9 ns per loop
You can run ruby commands in one line with the -e
flag:
ruby -e "puts 'hi'"
Check the man page for more information.
If I understand what you are asking, it is a regular expression like this:
^(8768|9875|2353)
This matches the three sets of digit strings at beginning of line only.
