You almost never want to use Read Uncommited
since it's not really ACID
compliant. Read Commmited
is a good default starting place. Repeatable Read
is probably only needed in reporting, rollup or aggregation scenarios. Note that many DBs, postgres included don't actually support Repeatable Read, you have to use Serializable
instead. Serializable
is useful for things that you know have to happen completely independently of anything else; think of it like synchronized
in Java. Serializable goes hand in hand with REQUIRES_NEW
propagation.
I use REQUIRES
for all functions that run UPDATE or DELETE queries as well as "service" level functions. For DAO level functions that only run SELECTs, I use SUPPORTS
which will participate in a TX if one is already started (i.e. being called from a service function).
All existing answers are correct, but I feel cannot give just this complex topic.
For a comprehensive, practical explanation you might want to have a look at this Spring @Transactional In-Depth guide, which tries its best to cover transaction management in ~4000 simple words, with a lot of code examples.
You can make a simple program to ask for the user's name and print whatever the reply use inputs.
Or ask the user to enter two numbers and you can add, multiply, subtract, or divide those numbers and print the answers for user inputs just like the behavior of a calculator.
So there you need the Scanner class. You have to import java.util.Scanner;
, and in the code you need to use:
Scanner input = new Scanner(System.in);
input
is a variable name.
Scanner input = new Scanner(System.in);
System.out.println("Please enter your name: ");
s = input.next(); // Getting a String value
System.out.println("Please enter your age: ");
i = input.nextInt(); // Getting an integer
System.out.println("Please enter your salary: ");
d = input.nextDouble(); // Getting a double
See how this differs: input.next();
, i = input.nextInt();
, d = input.nextDouble();
According to a String, int and a double varies the same way for the rest. Don't forget the import statement at the top of your code.
Your hack of decrementing the count at the end is exactly that -- a hack.
Far better to write your loop correctly in the first place, so it doesn't count the last line twice.
int main() {
int number_of_lines = 0;
std::string line;
std::ifstream myfile("textexample.txt");
while (std::getline(myfile, line))
++number_of_lines;
std::cout << "Number of lines in text file: " << number_of_lines;
return 0;
}
Personally, I think in this case, C-style code is perfectly acceptable:
int main() {
unsigned int number_of_lines = 0;
FILE *infile = fopen("textexample.txt", "r");
int ch;
while (EOF != (ch=getc(infile)))
if ('\n' == ch)
++number_of_lines;
printf("%u\n", number_of_lines);
return 0;
}
Edit: Of course, C++ will also let you do something a bit similar:
int main() {
std::ifstream myfile("textexample.txt");
// new lines will be skipped unless we stop it from happening:
myfile.unsetf(std::ios_base::skipws);
// count the newlines with an algorithm specialized for counting:
unsigned line_count = std::count(
std::istream_iterator<char>(myfile),
std::istream_iterator<char>(),
'\n');
std::cout << "Lines: " << line_count << "\n";
return 0;
}
There is also another solution which will be to override systemFont.
Just create a category
UIFont+SystemFontOverride.h
#import <UIKit/UIKit.h>
@interface UIFont (SystemFontOverride)
@end
UIFont+SystemFontOverride.m
@implementation UIFont (SystemFontOverride)
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wobjc-protocol-method-implementation"
+ (UIFont *)boldSystemFontOfSize:(CGFloat)fontSize {
return [UIFont fontWithName:@"fontName" size:fontSize];
}
+ (UIFont *)systemFontOfSize:(CGFloat)fontSize {
return [UIFont fontWithName:@"fontName" size:fontSize];
}
#pragma clang diagnostic pop
@end
This will replace the default implementation and most UIControls use systemFont.
The System.DateTime
class has a property called Now
, which:
Gets a
DateTime
object that is set to the current date and time on this computer, expressed as the local time.
You can set the Text
property of your label to the current time like this (where myLabel
is the name of your label):
myLabel.Text = DateTime.Now.ToString();
One more variant using extension
and argument name range
This extension uses Range
and ClosedRange
extension Array {
subscript (range r: Range<Int>) -> Array {
return Array(self[r])
}
subscript (range r: ClosedRange<Int>) -> Array {
return Array(self[r])
}
}
Tests:
func testArraySubscriptRange() {
//given
let arr = ["1", "2", "3"]
//when
let result = arr[range: 1..<arr.count] as Array
//then
XCTAssertEqual(["2", "3"], result)
}
func testArraySubscriptClosedRange() {
//given
let arr = ["1", "2", "3"]
//when
let result = arr[range: 1...arr.count - 1] as Array
//then
XCTAssertEqual(["2", "3"], result)
}
This is what I did on the controller
var collectionDate = '2002-04-26T09:00:00';
var date = new Date(collectionDate);
//then pushed all my data into an array $scope.rows which I then used in the directive
I ended up formatting the date to my desired pattern on the directive as follows.
var data = new google.visualization.DataTable();
data.addColumn('date', 'Dates');
data.addColumn('number', 'Upper Normal');
data.addColumn('number', 'Result');
data.addColumn('number', 'Lower Normal');
data.addRows(scope.rows);
var formatDate = new google.visualization.DateFormat({pattern: "dd/MM/yyyy"});
formatDate.format(data, 0);
//set options for the line chart
var options = {'hAxis': format: 'dd/MM/yyyy'}
//Instantiate and draw the chart passing in options
var chart = new google.visualization.LineChart($elm[0]);
chart.draw(data, options);
This gave me dates ain the format of dd/MM/yyyy (26/04/2002) on the x axis of the chart.
I know this is old, but for anyone else, make sure that the class that's missing is in the same package as the class where you get the error/where your calling it from.
It sounds like your error comes from an attempt to run something like this (which works in Linux)
NODE_ENV=development node foo.js
the equivalent in Windows would be
SET NODE_ENV=development
node foo.js
running in the same command shell. You mentioned set NODE_ENV did not work, but wasn't clear how/when you executed it.
While : your condition is at the begin of the loop block, and makes possible to never enter the loop.
Do While : your condition is at the end of the loop block, and makes obligatory to enter the loop at least one time.
You are right, the documentation lacks of those methods. However when I dug into rxjs repository, I found nice comments about tap (too long to paste here) and pipe operators:
/**
* Used to stitch together functional operators into a chain.
* @method pipe
* @return {Observable} the Observable result of all of the operators having
* been called in the order they were passed in.
*
* @example
*
* import { map, filter, scan } from 'rxjs/operators';
*
* Rx.Observable.interval(1000)
* .pipe(
* filter(x => x % 2 === 0),
* map(x => x + x),
* scan((acc, x) => acc + x)
* )
* .subscribe(x => console.log(x))
*/
Pipe: Used to stitch together functional operators into a chain. Before we could just do observable.filter().map().scan()
, but since every RxJS operator is a standalone function rather than an Observable's method, we need pipe()
to make a chain of those operators (see example above).
Tap: Can perform side effects with observed data but does not modify the stream in any way. Formerly called do()
. You can think of it as if observable was an array over time, then tap()
would be an equivalent to Array.forEach()
.
To expand on previous answers, the following one-liner exports a single table as a tab-separated file. It's suitable for automation, exporting the database every day or so.
mysql -B -D mydatabase -e 'select * from mytable'
Conveniently, we can use the same technique to list out MySQL's tables, and to describe the fields on a single table:
mysql -B -D mydatabase -e 'show tables'
mysql -B -D mydatabase -e 'desc users'
Field Type Null Key Default Extra
id int(11) NO PRI NULL auto_increment
email varchar(128) NO UNI NULL
lastName varchar(100) YES NULL
title varchar(128) YES UNI NULL
userName varchar(128) YES UNI NULL
firstName varchar(100) YES NULL
This is in slight response to Joel's comment about making a slighly more optimized version. Instead of returning a random date directly, why not return a generator function which can be called repeatedly to create a random date.
Func<DateTime> RandomDayFunc()
{
DateTime start = new DateTime(1995, 1, 1);
Random gen = new Random();
int range = ((TimeSpan)(DateTime.Today - start)).Days;
return () => start.AddDays(gen.Next(range));
}
Will take you to the master branch.
git checkout master
To switch to other branches do (ignore the square brackets, it's just for emphasis purposes)
git checkout [the name of the branch you want to switch to]
To create a new branch use the -b like this (ignore the square brackets, it's just for emphasis purposes)
git checkout -b [the name of the branch you want to create]
In Python 3 you can do it this way:
for item in range(1,10):
print(item, end =" ")
Outputs:
1 2 3 4 5 6 7 8 9
Tuple: You can do the same thing with a tuple:
tup = (1,2,3,4,5)
for n in tup:
print(n, end = " - ")
Outputs:
1 - 2 - 3 - 4 - 5 -
Another example:
list_of_tuples = [(1,2),('A','B'), (3,4), ('Cat', 'Dog')]
for item in list_of_tuples:
print(item)
Outputs:
(1, 2)
('A', 'B')
(3, 4)
('Cat', 'Dog')
You can even unpack your tuple like this:
list_of_tuples = [(1,2),('A','B'), (3,4), ('Cat', 'Dog')]
# Tuple unpacking so that you can deal with elements inside of the tuple individually
for (item1, item2) in list_of_tuples:
print(item1, item2)
Outputs:
1 2
A B
3 4
Cat Dog
another variation:
list_of_tuples = [(1,2),('A','B'), (3,4), ('Cat', 'Dog')]
for (item1, item2) in list_of_tuples:
print(item1)
print(item2)
print('\n')
Outputs:
1
2
A
B
3
4
Cat
Dog
Some libraries (e.g. a Java interop library that I use) require values to be passed in a row at a time, for example, if streaming data. To replicate the streaming nature, I 'stream' my dataframe values one by one, I wrote the below, which comes in handy from time to time.
class DataFrameReader:
def __init__(self, df):
self._df = df
self._row = None
self._columns = df.columns.tolist()
self.reset()
self.row_index = 0
def __getattr__(self, key):
return self.__getitem__(key)
def read(self) -> bool:
self._row = next(self._iterator, None)
self.row_index += 1
return self._row is not None
def columns(self):
return self._columns
def reset(self) -> None:
self._iterator = self._df.itertuples()
def get_index(self):
return self._row[0]
def index(self):
return self._row[0]
def to_dict(self, columns: List[str] = None):
return self.row(columns=columns)
def tolist(self, cols) -> List[object]:
return [self.__getitem__(c) for c in cols]
def row(self, columns: List[str] = None) -> Dict[str, object]:
cols = set(self._columns if columns is None else columns)
return {c : self.__getitem__(c) for c in self._columns if c in cols}
def __getitem__(self, key) -> object:
# the df index of the row is at index 0
try:
if type(key) is list:
ix = [self._columns.index(key) + 1 for k in key]
else:
ix = self._columns.index(key) + 1
return self._row[ix]
except BaseException as e:
return None
def __next__(self) -> 'DataFrameReader':
if self.read():
return self
else:
raise StopIteration
def __iter__(self) -> 'DataFrameReader':
return self
Which can be used:
for row in DataFrameReader(df):
print(row.my_column_name)
print(row.to_dict())
print(row['my_column_name'])
print(row.tolist())
And preserves the values/ name mapping for the rows being iterated. Obviously, is a lot slower than using apply and Cython as indicated above, but is necessary in some circumstances.
If your system clock is set properly and hasn't wrapped around, and if your NIC has its own MAC (i.e. you haven't set a custom MAC) and your NIC vendor has not been recycling MACs (which they are not supposed to do but which has been known to occur), and if your system's GUID generation function is properly implemented, then your system will never generate duplicate GUIDs.
If everyone on earth who is generating GUIDs follows those rules then your GUIDs will be globally unique.
In practice, the number of people who break the rules is low, and their GUIDs are unlikely to "escape". Conflicts are statistically improbable.
Here's my Swift solution. In your subclass of UIViewController, override the navigationShouldPopOnBackButton method.
extension UIViewController {
func navigationShouldPopOnBackButton() -> Bool {
return true
}
}
extension UINavigationController {
func navigationBar(navigationBar: UINavigationBar, shouldPopItem item: UINavigationItem) -> Bool {
if let vc = self.topViewController {
if vc.navigationShouldPopOnBackButton() {
self.popViewControllerAnimated(true)
} else {
for it in navigationBar.subviews {
let view = it as! UIView
if view.alpha < 1.0 {
[UIView .animateWithDuration(0.25, animations: { () -> Void in
view.alpha = 1.0
})]
}
}
return false
}
}
return true
}
}
You can use the "export" solution just like what other guys have suggested. I'd like to provide you with another solution for permanent convenience: you can use any path as GOPATH when running Go commands.
Firstly, you need to download a small tool named gost
: https://github.com/byte16/gost/releases . If you use ubuntu, you can download the linux version(https://github.com/byte16/gost/releases/download/v0.1.0/gost_linux_amd64.tar.gz).
Then you need to run the commands below to unpack it :
$ cd /path/to/your/download/directory
$ tar -xvf gost_linux_amd64.tar.gz
You would get an executable gost
. You can move it to /usr/local/bin
for convenient use:
$ sudo mv gost /usr/local/bin
Run the command below to add the path you want to use as GOPATH into the pathspace gost
maintains. It is required to give the path a name which you would use later.
$ gost add foo /home/foobar/bar # 'foo' is the name and '/home/foobar/bar' is the path
Run any Go command you want in the format:
gost goCommand [-p {pathName}] -- [goFlags...] [goArgs...]
For example, you want to run go get github.com/go-sql-driver/mysql
with /home/foobar/bar
as the GOPATH, just do it as below:
$ gost get -p foo -- github.com/go-sql-driver/mysql # 'foo' is the name you give to the path above.
It would help you to set the GOPATH and run the command. But remember that you have added the path into gost
's pathspace. If you are under any level of subdirectories of /home/foobar/bar
, you can even just run the command below which would do the same thing for short :
$ gost get -- github.com/go-sql-driver/mysql
gost
is a Simple Tool of Go which can help you to manage GOPATHs and run Go commands. For more details about how to use it to run other Go commands, you can just run gost help goCmdName
. For example you want to know more about install
, just type words below in:
$ gost help install
You can also find more details in the README of the project: https://github.com/byte16/gost/blob/master/README.md
You can parse the list as a string and use of the eval
builtin function to read it as a list. In this case, you will have to put single quotes into double quote (or the way around) in order to ensure successful string parse.
# declare the list arg as a string
parser.add_argument('-l', '--list', type=str)
# parse
args = parser.parse()
# turn the 'list' string argument into a list object
args.list = eval(args.list)
print(list)
print(type(list))
Testing:
python list_arg.py --list "[1, 2, 3]"
[1, 2, 3]
<class 'list'>
This is one way I found. You can add a hidden button:
<button id="openModalButton" [hidden]="true" data-toggle="modal" data-target="#myModal">Open Modal</button>
Then use the code to "click" the button to open the modal:
document.getElementById("openModalButton").click();
This way can keep the bootstrap style of the modal and the fade in animation.
There are several ways that you can transform data from multiple rows into columns.
PIVOT
In SQL Server you can use the PIVOT
function to transform the data from rows to columns:
select Firstname, Amount, PostalCode, LastName, AccountNumber
from
(
select value, columnname
from yourtable
) d
pivot
(
max(value)
for columnname in (Firstname, Amount, PostalCode, LastName, AccountNumber)
) piv;
See Demo.
columnnames
If you have an unknown number of columnnames
that you want to transpose, then you can use dynamic SQL:
DECLARE @cols AS NVARCHAR(MAX),
@query AS NVARCHAR(MAX)
select @cols = STUFF((SELECT ',' + QUOTENAME(ColumnName)
from yourtable
group by ColumnName, id
order by id
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set @query = N'SELECT ' + @cols + N' from
(
select value, ColumnName
from yourtable
) x
pivot
(
max(value)
for ColumnName in (' + @cols + N')
) p '
exec sp_executesql @query;
See Demo.
If you do not want to use the PIVOT
function, then you can use an aggregate function with a CASE
expression:
select
max(case when columnname = 'FirstName' then value end) Firstname,
max(case when columnname = 'Amount' then value end) Amount,
max(case when columnname = 'PostalCode' then value end) PostalCode,
max(case when columnname = 'LastName' then value end) LastName,
max(case when columnname = 'AccountNumber' then value end) AccountNumber
from yourtable
See Demo.
This could also be completed using multiple joins, but you will need some column to associate each of the rows which you do not have in your sample data. But the basic syntax would be:
select fn.value as FirstName,
a.value as Amount,
pc.value as PostalCode,
ln.value as LastName,
an.value as AccountNumber
from yourtable fn
left join yourtable a
on fn.somecol = a.somecol
and a.columnname = 'Amount'
left join yourtable pc
on fn.somecol = pc.somecol
and pc.columnname = 'PostalCode'
left join yourtable ln
on fn.somecol = ln.somecol
and ln.columnname = 'LastName'
left join yourtable an
on fn.somecol = an.somecol
and an.columnname = 'AccountNumber'
where fn.columnname = 'Firstname'
dynamic MyDynamic = new ExpandoObject();
I am working on C# 9 and .NET 5, example
foo
is nullable int, I need get int value of foo
var foo = (context as AccountTransfer).TransferSide;
int value2 = 0;
if (foo != null)
{
value2 = foo.Value;
}
$(".list li").sort(asc_sort).appendTo('.list');
//$("#debug").text("Output:");
// accending sort
function asc_sort(a, b){
return ($(b).text()) < ($(a).text()) ? 1 : -1;
}
// decending sort
function dec_sort(a, b){
return ($(b).text()) > ($(a).text()) ? 1 : -1;
}
live demo : http://jsbin.com/eculis/876/edit
Try this code. You don't require the parse function because your data type is JSON so it is return JSON object.
$.ajax({
url : base_url+"Login/submit",
type: "POST",
dataType: "json",
data : {
'username': username,
'password': password
},
success: function(data)
{
alert(data.status);
}
});
I think this will do:
$('#'+div_id+' .widget-head > span').text("new dialog title");
You can't do this using forms the normal way. Instead, you want to use AJAX.
A sample function that will submit the data and alert the page response.
function submitForm() {
var http = new XMLHttpRequest();
http.open("POST", "<<whereverTheFormIsGoing>>", true);
http.setRequestHeader("Content-type","application/x-www-form-urlencoded");
var params = "search=" + <<get search value>>; // probably use document.getElementById(...).value
http.send(params);
http.onload = function() {
alert(http.responseText);
}
}
If you want the onload method to take parameters, you can do something similar to this:
window.onload = function() {
yourFunction(param1, param2);
};
This binds onload to an anonymous function, that when invoked, will run your desired function, with whatever parameters you give it. And, of course, you can run more than one function from inside the anonymous function.
OFFICE 2013 INSTRUCTIONS:
(For Windows 7 (x64) | MS Office 32-Bit)
Option 1 | Check if ability already exists | 2 minutes
Option 2 | The "Monthview" Control doesn't currently exist | 5 minutes
Okay, either of these two steps should work for you if you have Office 2013 (32-Bit) on Windows 7 (x64). Some of the steps may be different if you have a different combo of Windows 7 & Office 2013.
The "Monthview" control will be your fully fleshed out 'DatePicker'. It comes equipped with its own properties and image. It works very well. Good luck.

Actually you have a code compiled targeting a higher JDK (JDK 1.8 in your case) but at runtime you are supplying a lower JRE(JRE 7 or below).
you can fix this problem by adding target parameter while compilation
e.g. if your runtime target is 1.7, you should use 1.7 or below
javac -target 1.7 *.java
if you are using eclipse, you can sent this parameter at Window -> Preferences -> Java -> Compiler -> set "Compiler compliance level" = choose your runtime jre version or lower.
I'd like to share my steps which is a bit different to what offered by rynop and superluminary.
A
Record is exactly the same but CNAME
for www
I would prefer to redirect it to my blank domain (non-www
)This configuration is referring to guidance of preferred domain. The domain setting of www
to non www
or vise versa can be different on each of the domain providers. Since my domain is under GoDaddy, so under the Domain Setting I set it using the Subdomain Forwarding (301).
As the result of pointing the domain to Github repository, it will then give all the URLs for both of master
and gh-pages
branch similar like the ones I listed below goes to the preferred domain:
master
By creating CNAME
file on master
branch (check it on my user repository).
http://hyipworld.github.io/
http://www.hyip.world/

gh-pages
By creating the same CNAME
file on gh-pages
branch (check it on my project repository).

http://www.hyip.world/maps/

As addition to the CNAME
file above, you may need to completely bypass Jekyll processing on GitHub Pages by creating a file named .nojekyll
in the root of your pages repo.

Like it has been said few times, you need to change your selector to

But I want to add, you have to use single or double quotes when using [] in selector.
Just addressing the edit.
@nzcoops, you do not need the column names in a comma delimited character vector. You are thinking about this the wrong way round. When you do
vec <- c("col1", "col2", "col3")
you are creating a character vector. The ,
just separates arguments taken by the c()
function when you define that vector. names()
and similar functions return a character vector of names.
> dat <- data.frame(col1 = 1:3, col2 = 1:3, col3 = 1:3)
> dat
col1 col2 col3
1 1 1 1
2 2 2 2
3 3 3 3
> names(dat)
[1] "col1" "col2" "col3"
It is far easier and less error prone to select from the elements of names(dat)
than to process its output to a comma separated string you can cut and paste from.
Say we want columns col1
and col2
, subset names(dat)
, retaining only the ones we want:
> names(dat)[c(1,3)]
[1] "col1" "col3"
> dat[, names(dat)[c(1,3)]]
col1 col3
1 1 1
2 2 2
3 3 3
You can kind of do what you want, but R will always print the vector the screen in quotes "
:
> paste('"', names(dat), '"', sep = "", collapse = ", ")
[1] "\"col1\", \"col2\", \"col3\""
> paste("'", names(dat), "'", sep = "", collapse = ", ")
[1] "'col1', 'col2', 'col3'"
so the latter may be more useful. However, now you have to cut and past from that string. Far better to work with objects that return what you want and use standard subsetting routines to keep what you need.
The Address property of a cell can get this for you:
MsgBox Cells(1, 1).Address(RowAbsolute:=False, ColumnAbsolute:=False)
returns A1
.
The other way around can be done with the Row
and Column
property of Range
:
MsgBox Range("A1").Row & ", " & Range("A1").Column
returns 1,1
.

add one folder any name e.g public and add .htaccess file and write allow from all it means, in this folder your all files and all folder will not give error Access forbidden! use it like this

<script type="text/javascript" src="<?php echo base_url(); ?>application/public/js/javascript.js"></script>
There are two ways this could be achieved.

To achieve this you can use a Regular Expression to remove all the whitespace in the string. If the length of the resulting string is 0
, then you can be sure the original only contained whitespace. Try this:

The advantage is that Object.create
is typically slower than new
on most browsers
In this jsperf example, in a Chromium, browser new
is 30 times as fast as Object.create(obj)
although both are pretty fast. This is all pretty strange because new does more things (like invoking a constructor) where Object.create should be just creating a new Object with the passed in object as a prototype (secret link in Crockford-speak)
Perhaps the browsers have not caught up in making Object.create
more efficient (perhaps they are basing it on new
under the covers ... even in native code)

I asked the same question some time ago and had to answer it myself. Here's what I came up with:
It seems, my first thought [that it comes from its JavaScript roots] was correct.
'\/' === '/'
in JavaScript, and JSON is valid JavaScript. However, why are the other ignored escapes (like\z
) not allowed in JSON?The key for this was reading http://www.cs.tut.fi/~jkorpela/www/revsol.html, followed by http://www.w3.org/TR/html4/appendix/notes.html#h-B.3.2. The feature of the slash escape allows JSON to be embedded in HTML (as SGML) and XML.
Comment in the normal feed are blocked. Let me write why this happens, just like when you executed your app.
If you ran scripts, python or ipython in another environment than the one you installed it, you will get these issues.
Don't confuse reinstalling it. Matplotlib is normally installed in your user environment, not in sudo. You are changing the environment.
So don't reinstall pip, just make sure you are running it as sudo if you installed it in the sudo environment.
When I've done this, rather than fiddling the original migration, I create a new one with just the add column in the up section and a drop column in the down section.
You can change the original and rerun it if you migrate down between, but in this case I think that's made a migration that won't work properly.
As currently posted, you're adding the column and then creating the table.
If you change the order it might work. Or, as you're modifying an existing migration, just add it to the create table instead of doing a separate add column.
You should have to use DateTime.TryParseExact
.
var newDate = DateTime.ParseExact("20111120",
"yyyyMMdd",
CultureInfo.InvariantCulture);
OR
string str = "20111021";
string[] format = {"yyyyMMdd"};
DateTime date;
if (DateTime.TryParseExact(str,
format,
System.Globalization.CultureInfo.InvariantCulture,
System.Globalization.DateTimeStyles.None,
out date))
{
//valid
}
function zeroFill(number, width) {
width -= (number.toString().length - /\./.test(number));
if (width > 0) {
return new Array(width + 1).join('0') + number;
}
return number + ""; // always return a string
}
Slight changes made to Peter's code. With his code if the input is (1.2, 3) the value returned should be 01.2 but it is returning 1.2. The changes here should correct that.
My own humble (case sensitive) solution:
uint8_t strContains(char* string, char* toFind)
{
uint8_t slen = strlen(string);
uint8_t tFlen = strlen(toFind);
uint8_t found = 0;
if( slen >= tFlen )
{
for(uint8_t s=0, t=0; s<slen; s++)
{
do{
if( string[s] == toFind[t] )
{
if( ++found == tFlen ) return 1;
s++;
t++;
}
else { s -= found; found=0; t=0; }
}while(found);
}
return 0;
}
else return -1;
}
Results
strContains("this is my sample example", "th") // 1
strContains("this is my sample example", "sample") // 1
strContains("this is my sample example", "xam") // 1
strContains("this is my sample example", "ple") // 1
strContains("this is my sample example", "ssample") // 0
strContains("this is my sample example", "samplee") // 0
strContains("this is my sample example", "") // 0
strContains("str", "longer sentence") // -1

use this
$("a").each(function () {

You can use the begin
and end
functions from the Boost range library to easily find the ends of a primitive array, and unlike the macro solution, this will give a compile error instead of broken behaviour if you accidentally apply it to a pointer.
const char* array[] = { "cat", "dog", "horse" };
vector<string> vec(begin(array), end(array));
This is more advice than a specific answer, but my suggestion is to convert dates to date variables immediately, rather than keeping them as strings. This way you can use date (and time) functions on them, rather than trying to use very troublesome workarounds.
As pointed out, the lubridate package has nice extraction functions.
For some projects, I have found that piecing dates out from the start is helpful: create year, month, day (of month) and day (of week) variables to start with. This can simplify summaries, tables and graphs, because the extraction code is separate from the summary/table/graph code, and because if you need to change it, you don't have to roll out those changes in multiple spots.
You need to install newest version of xCode from appStore. It contains the compiler for C(gcc) and C++(g++) for mac. Then you can install pandas without any problem. Use the following commands in terminal:
xcode-select --install
pip3 install pandas
It might take some time as it installs other packages too. Please be patient.
Make sure you select the function that needs to be executed. See screenshot:
A very old but simple enough technique is to use "Server-Side Includes", to include HTML pages into a top-level page that has the .shtml
extension. For instance this would be your index.shtml
file:
<html>
<head>...</head>
<body>
<!-- repeated header: note that the #include is in a HTML comment -->
<!--#include file="header.html" -->
<!-- unique content here... -->
</body>
</html>
Yes, it is lame, but it works. Remember to enable SSI support in your HTTP server configuration (this is how to do it for Apache).
VB6 Installs just fine on Windows 7 (and Windows 8 / Windows 10) with a few caveats.
Here is how to install it:
C:\Windows
called MSJAVA.DLL
. The setup process will look for this file, and if it doesn't find it, will force an installation of old, old Java, and require a reboot. By creating the zero-byte file, the installation of moldy Java is bypassed, and no reboot will be required.SETUP.EXE
, select Run As Administrator
.C:\Program Files\Microsoft Visual Studio\VB98\
After changing these settings, fire up the IDE, and things should be back to normal, and the IDE is no longer sluggish.

I have got a answer for Hibernate Query Language to use Distinct fields. You can use *SELECT DISTINCT(TO_CITY) FROM FLIGHT_ROUTE*. If you use SQL query, it return String List. You can't use it return value by Entity Class. So the Answer to solve that type of Problem is use HQL with SQL.
FROM FLIGHT_ROUTE F WHERE F.ROUTE_ID IN (SELECT SF.ROUTE_ID FROM FLIGHT_ROUTE SF GROUP BY SF.TO_CITY);
From SQL query statement it got DISTINCT ROUTE_ID and input as a List. And IN query filter the distinct TO_CITY from IN (List).
Return type is Entity Bean type. So you can it in AJAX such as AutoComplement.
May all be OK
Oftentimes you see the suggestion use use keyword arguments, with default values, instead. Look into that.
dropdowns always show up on top, only solution for this problem is to hide dropdowns when image is displayed (display:block or visibility:visibile) and show them when image hidden (display:none or visibility:hidden)
// The below C++ function checks for a palindrome and
// returns true if it is a palindrome and returns false otherwise
bool checkPalindrome ( string s )
{
// This calculates the length of the string
int n = s.length();
// the for loop iterates until the first half of the string
// and checks first element with the last element,
// second element with second last element and so on.
// if those two characters are not same, hence we return false because
// this string is not a palindrome
for ( int i = 0; i <= n/2; i++ )
{
if ( s[i] != s[n-1-i] )
return false;
}
// if the above for loop executes completely ,
// this implies that the string is palindrome,
// hence we return true and exit
return true;
}
Here is another solution: generate a bash script with all the variables and the contents of the template file, that script would look like this:
word=dog
i=1
cat << EOF
the number is ${i}
the word is ${word}
EOF
If we feed this script into bash it would produce the desired output:
the number is 1
the word is dog
Here is how to generate that script and feed that script into bash:
(
# Variables
echo word=dog
echo i=1
# add the template
echo "cat << EOF"
cat template.txt
echo EOF
) | bash
cat
command with HEREDOCIf you want to redirect this output into a file, replace the last line with:
) | bash > output.txt
Or you can do the same using sql query:
Click on SQL present along side Structure
TRUNCATE tablename; //offers better performance, but used only when all entries need to be cleared
or
DELETE FROM tablename; //returns the number of rows deleted
Use Comparator
and then put objects into Collection
, then Collections.sort();
class Person {
String fname;
String lname;
int age;
public Person() {
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getFname() {
return fname;
}
public void setFname(String fname) {
this.fname = fname;
}
public String getLname() {
return lname;
}
public void setLname(String lname) {
this.lname = lname;
}
public Person(String fname, String lname, int age) {
this.fname = fname;
this.lname = lname;
this.age = age;
}
@Override
public String toString() {
return fname + "," + lname + "," + age;
}
}
public class Main{
public static void main(String[] args) {
List<Person> persons = new java.util.ArrayList<Person>();
persons.add(new Person("abc3", "def3", 10));
persons.add(new Person("abc2", "def2", 32));
persons.add(new Person("abc1", "def1", 65));
persons.add(new Person("abc4", "def4", 10));
System.out.println(persons);
Collections.sort(persons, new Comparator<Person>() {
@Override
public int compare(Person t, Person t1) {
return t.getAge() - t1.getAge();
}
});
System.out.println(persons);
}
}
All kernels will use some assembly code as well.
This answer came up when searching for "java invert boolean function". The example below will prevent certain static analysis tools from failing builds due to branching logic. This is useful if you need to invert a boolean and haven't built out comprehensive unit tests ;)
Boolean.valueOf(aBool).equals(false)
or alternatively:
Boolean.FALSE.equals(aBool)
or
Boolean.FALSE::equals
TLDR if you don't want to read all these great answers :-)

Using DateTimeOffset
because the timezone is forced to UTC+0.

You just need to open it in popup using JavaScript or load it to iframe
. Simple and works - that's what I was looking for!
I checked that you can't really embed any video to LinkedIn post, the only option is to add the link to the page with video itself.
You can achieve it by putting YT link into url
param:
https://www.linkedin.com/shareArticle?mini=true&url=https://www.youtube.com/watch?v=SBi92AOSW2E
If you specify summary
and title
then LinkedIn will stop pulling it from the video, e.g.:
It does work exactly the same with Vimeo, and probably will work for any website. Hope it will help.
When you open above links you will see that LinkedIn loads some images along with the passed URL (and optionally title and summary).
LinkedIn does it automatically, and you can read about it here: https://developer.linkedin.com/docs/share-on-linkedin#opengraph
It's interesting though as it says:
If Open Graph tags are present, LinkedIn's crawler will not have to rely on it's own analysis to determine what content will be shared, which improves the likelihood that the information that is shared is exactly what you intended.
It tells me that even if Open Graph information is not attached, LinkedIn can pull this data based on its own analysis. And in case of YouTube it seems to be the case, as I couldn't find any Open Graph tags added to YouTube pages.
Get the time in milliseconds, minus your minutes in milliseconds and convert it to Date. Here you need to objectify one!!!
int minutes = 60;
long currentDateTime = System.currentTimeMillis();
Date currentDate = new Date(currentDateTime - minutes*60*1000);
System.out.println(currentDate);
You can use jQuery like this:
$(function() {
$("#form").submit(function(event) {
// do some validation, for example:
username = $("#username").val();
if (username.length >= 8)
return; // valid
event.preventDefault(); // invalidates the form
});
});
In your HTML:
<form id="form" method="post">
<input type="text" name="username" required id="username">
<button type="submit">Submit</button>
</form>

There're 3 ways to achieve this after conda
4.6. (The last method has the highest priority.)
Use sub-command conda config
to change the setting.
conda config --set auto_activate_base false
In fact, the former conda config
sub-command is changing configuration file .condarc
. We can modify .condarc
directly. Add following content into .condarc
under your home directory,
# auto_activate_base (bool)
# Automatically activate the base environment during shell
# initialization. for `conda init`
auto_activate_base: false
Set environment variable CONDA_AUTO_ACTIVATE_BASE
in the shell's init file. (.bashrc
for bash, .zshrc
for zsh)
CONDA_AUTO_ACTIVATE_BASE=false
To convert from the
condarc
file-based configuration parameter name to the environment variable parameter name, make the name all uppercase and prependCONDA_
. For example, conda’salways_yes
configuration parameter can be specified using aCONDA_ALWAYS_YES
environment variable.
The environment settings take precedence over corresponding settings in .condarc
file.
Like the other answers you can do theTypeIs = Object.keys(myVar)[0];
to get the first key. If you are expecting more keys, you can use
Object.keys(myVar).forEach(function(k) {
if(k === "typeA") {
// do stuff
}
else if (k === "typeB") {
// do more stuff
}
else {
// do something
}
});
Change the active scheme Device from Simulator to Generic iOS Device
To use the callback style (https://facebook.github.io/react/docs/refs-and-the-dom.html) as recommended on React's documentation you can add a definition for a property on the class:
export class Foo extends React.Component<{}, {}> {
// You don't need to use 'references' as the name
references: {
// If you are using other components be more specific than HTMLInputElement
myRef: HTMLInputElement;
} = {
myRef: null
}
...
myFunction() {
// Use like this
this.references.myRef.focus();
}
...
render() {
return(<input ref={(i: any) => { this.references.myRef = i; }}/>)
}
From the output of java -X
:
-Xloggc:<file> log GC status to a file with time stamps
Documented here:
-Xloggc:filename
Sets the file to which verbose GC events information should be redirected for logging. The information written to this file is similar to the output of
-verbose:gc
with the time elapsed since the first GC event preceding each logged event. The-Xloggc
option overrides-verbose:gc
if both are given with the samejava
command.Example:
-Xloggc:garbage-collection.log
So the output looks something like this:
0.590: [GC 896K->278K(5056K), 0.0096650 secs] 0.906: [GC 1174K->774K(5056K), 0.0106856 secs] 1.320: [GC 1670K->1009K(5056K), 0.0101132 secs] 1.459: [GC 1902K->1055K(5056K), 0.0030196 secs] 1.600: [GC 1951K->1161K(5056K), 0.0032375 secs] 1.686: [GC 1805K->1238K(5056K), 0.0034732 secs] 1.690: [Full GC 1238K->1238K(5056K), 0.0631661 secs] 1.874: [GC 62133K->61257K(65060K), 0.0014464 secs]
An alternative to the answer from sergey_mo is to create multiple ssh keys on the jenkins server.
(Though as the first commenter to sergey_mo's answer said, this may end up being more painful than managing a single key-pair.)
Considering this still shows up when we search for EF in .NET Core, I'll post my answer here (Since it has haunted me a lot). Note that there are some subtleties with the EF 6 .NET version (No initial command, and you will need to delete "Snapshot" files)
(Tested in .NET Core 2.1)
Here are the steps:
_efmigrationhistory
table.ApplicationDbContextSnapshot.cs
, and delete them.Add-Migration InitialMigration
Please note: You must delete ALL the Snapshot files. I spent countless hours just deleting the database... This will generate an empty migration if you don't do it.
Also, in #3 you can just name your migration however you want.
Here are some additional resources: asp.net CORE Migrations generated empty
When applying CSS, apply it to a class and try to avoid as much as you can to an id. The ID should only be used in JavaScript to fetch the element or for any event binding.
Classes should be used to apply CSS.
Sometimes you do have to use classes for event binding. In such cases, try to avoid classes which are being used for applying CSS and rather add new classes which doesn't have corresponding CSS. This will come to help when you need to change the CSS for any class or change the CSS class name all together for any element.
You must group both columns, group and sub-group, then use the aggregate function COUNT()
.
SELECT
group, subgroup, COUNT(*)

let oldHideView2 = view2.isHidden
view1.layer.removeAllAnimations()
view2.layer.removeAllAnimations()

Basic method to break the loop, using Breaks class. By declaring the loop as breakable.
The long boring solution, which is not involved with CLI, you can manually navigate to:
your local repo folder ? .git folder (hidden) ? config file
then choose your text editor to open it and look for url located under the [remote "origin"] section.
Why don't You just use:
label {
display: block;
width: 50px;
height: 24px;
float: left;
}
If you need more fine-grade control, you can also go the fork
pipe
exec
route. This will allow your application to retrieve the data outputted from the shell script.
First you need an object
public class MyObject {
public string Id {get;set;}
public string Text {get;set;}
...
}
Then in here
using (var twitpicResponse = (HttpWebResponse)request.GetResponse()) {
using (var reader = new StreamReader(twitpicResponse.GetResponseStream())) {
JavaScriptSerializer js = new JavaScriptSerializer();
var objText = reader.ReadToEnd();
MyObject myojb = (MyObject)js.Deserialize(objText,typeof(MyObject));
}
}
I haven't tested with the hierarchical object you have, but this should give you access to the properties you want.

<div *ngSwitchCase="2">Second Number</div>
<div *ngSwitchCase="3">Third Number</div>

<!-- foo = 3 -->
<ng-template [ngIf]="foo === 1">First Number</ng-template>
<ng-template [ngIf]="foo === 2">Second Number</ng-template>

<!-- If Statement -->
<ng-template #t13>
Template for foo between 1 and 3
</ng-template>
<!-- If Else Statement -->
<ng-template #t46>
Template for foo between 4 and 6
</ng-template>
<!-- Else Statement -->
<ng-template #t7>
Template for foo greater than 7
</ng-template>
Note: You can choose any format, but notice every code has own problems
In order to include the number of row index "columns" in your total shape I would personally add together the number of columns df.columns.size
with the attribute pd.Index.nlevels
/pd.MultiIndex.nlevels
:
Set up dummy data
import pandas as pd
flat_index = pd.Index([0, 1, 2])
multi_index = pd.MultiIndex.from_tuples([("a", 1), ("a", 2), ("b", 1), names=["letter", "id"])
columns = ["cat", "dog", "fish"]
data = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
flat_df = pd.DataFrame(data, index=flat_index, columns=columns)
multi_df = pd.DataFrame(data, index=multi_index, columns=columns)
# Show data
# -----------------
# 3 columns, 4 including the index
print(flat_df)
cat dog fish
id
0 1 2 3
1 4 5 6
2 7 8 9
# -----------------
# 3 columns, 5 including the index
print(multi_df)
cat dog fish
letter id
a 1 1 2 3
2 4 5 6
b 1 7 8 9
Writing our process as a function:
def total_ncols(df, include_index=False):
ncols = df.columns.size
if include_index is True:
ncols += df.index.nlevels
return ncols
print("Ignore the index:")
print(total_ncols(flat_df), total_ncols(multi_df))
print("Include the index:")
print(total_ncols(flat_df, include_index=True), total_ncols(multi_df, include_index=True))
This prints:
Ignore the index:
3 3
Include the index:
4 5
If you want to only include the number of indices if the index is a pd.MultiIndex
, then you can throw in an isinstance
check in the defined function.
As an alternative, you could use df.reset_index().columns.size
to achieve the same result, but this won't be as performant since we're temporarily inserting new columns into the index and making a new index before getting the number of columns.
using LINQ query expression
IEnumerable<SelectListItem> stores =
from store in database.Stores
where store.CompanyID == curCompany.ID
select new SelectListItem { Value = store.Name, Text = store.ID };
ViewBag.storeSelector = stores;
or using LINQ extension methods with lambda expressions
IEnumerable<SelectListItem> stores = database.Stores
.Where(store => store.CompanyID == curCompany.ID)
.Select(store => new SelectListItem { Value = store.Name, Text = store.ID });
ViewBag.storeSelector = stores;
One of the Related posts gave me the (simple) answer.
Apparently the auto
value on the grid-template-rows
property does exactly what I was looking for.
.grid {
display:grid;
grid-template-columns: 1fr 1.5fr 1fr;
grid-template-rows: auto auto 1fr 1fr 1fr auto auto;
grid-gap:10px;
height: calc(100vh - 10px);
}
I think your code is a bit too complicated and it needs more structure, because otherwise you'll be lost in all equations and operations. In the end this regression boils down to four operations:
In your case, I guess you have confused m
with n
. Here m
denotes the number of examples in your training set, not the number of features.
Let's have a look at my variation of your code:
import numpy as np
import random
# m denotes the number of examples here, not the number of features
def gradientDescent(x, y, theta, alpha, m, numIterations):
xTrans = x.transpose()
for i in range(0, numIterations):
hypothesis = np.dot(x, theta)
loss = hypothesis - y
# avg cost per example (the 2 in 2*m doesn't really matter here.
# But to be consistent with the gradient, I include it)
cost = np.sum(loss ** 2) / (2 * m)
print("Iteration %d | Cost: %f" % (i, cost))
# avg gradient per example
gradient = np.dot(xTrans, loss) / m
# update
theta = theta - alpha * gradient
return theta
def genData(numPoints, bias, variance):
x = np.zeros(shape=(numPoints, 2))
y = np.zeros(shape=numPoints)
# basically a straight line
for i in range(0, numPoints):
# bias feature
x[i][0] = 1
x[i][1] = i
# our target variable
y[i] = (i + bias) + random.uniform(0, 1) * variance
return x, y
# gen 100 points with a bias of 25 and 10 variance as a bit of noise
x, y = genData(100, 25, 10)
m, n = np.shape(x)
numIterations= 100000
alpha = 0.0005
theta = np.ones(n)
theta = gradientDescent(x, y, theta, alpha, m, numIterations)
print(theta)
At first I create a small random dataset which should look like this:
As you can see I also added the generated regression line and formula that was calculated by excel.
You need to take care about the intuition of the regression using gradient descent. As you do a complete batch pass over your data X, you need to reduce the m-losses of every example to a single weight update. In this case, this is the average of the sum over the gradients, thus the division by m
.
The next thing you need to take care about is to track the convergence and adjust the learning rate. For that matter you should always track your cost every iteration, maybe even plot it.
If you run my example, the theta returned will look like this:
Iteration 99997 | Cost: 47883.706462
Iteration 99998 | Cost: 47883.706462
Iteration 99999 | Cost: 47883.706462
[ 29.25567368 1.01108458]
Which is actually quite close to the equation that was calculated by excel (y = x + 30). Note that as we passed the bias into the first column, the first theta value denotes the bias weight.
There's now add_row()
from the tibble
or tidyverse
packages.
library(tidyverse)
df %>% add_row(hello = "hola", goodbye = "ciao")
Unspecified columns get an NA
.
There are two solutions to this:
a) Set your PATH variable to include "/usr/local/bin"
export PATH="$PATH:/usr/local/bin"
b) Create a symlink to "/usr/bin" which is already in your PATH
ln -s /usr/bin/nodejs /usr/bin/node
I hope it helps.

In my case the issue was not resolved because i did not restart my system. Please make sure you do restart your system.
I came across exactly the same issue quite recently. After reading many different advices which none of them worked for me, I finally went under the hood and found the root cause of the issue.
Mobile provisioning file actually DOESN'T match with the Entitlements file generated by Xcode.
Although all files are anaged automatically by Apple tool, they are not correct.
If you download provisioning file from Apple portal and open it (you can open it because it's just plist file signed by your certificate, so it's readable by text editor) and compare it with your Entitlements file (automatically generated by Xcode and residing in project files (so it's again plist XML file readable by text editor). Then you can see the difference.
In my case it was Game Center entitlement. It was displayed on the portal as checked (checked by default) but actually this entitlement was not included in mobile provisioning file. So it was matter of deleting it from Entitlements file.
So the result is - content of mobile provisioning profile sometimes doesn't match with what is displayed on the APP ID configuration page.

While searching for the best method to sum an array, I wrote a performance test.
In Chrome, "reduce" seems to be vastly superior
I hope this helps
// Performance test, sum of an array
var array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
var result = 0;
// Eval
console.time("eval");
for(var i = 0; i < 10000; i++) eval("result = (" + array.join("+") + ")");
console.timeEnd("eval");
// Loop
console.time("loop");
for(var i = 0; i < 10000; i++){
result = 0;
for(var j = 0; j < array.length; j++){
result += parseInt(array[j]);
}
}
console.timeEnd("loop");
// Reduce
console.time("reduce");
for(var i = 0; i < 10000; i++) result = array.reduce(function(pv, cv) { return pv + parseInt(cv); }, 0);
console.timeEnd("reduce");
// While
console.time("while");
for(var i = 0; i < 10000; i++){
j = array.length;
result = 0;
while(j--) result += array[i];
}
console.timeEnd("while");

You've answered the question with this statement:
Cron calls this
.sh
every 2 minutes
Cron does not run in a terminal, so why would you expect one to be set?
The most common reason for getting this error message is because the script attempts to source the user's .profile
which does not check that it's running in a terminal before doing something tty related. Workarounds include using a shebang line like:
#!/bin/bash -p
Which causes the sourcing of system-level profile scripts which (one hopes) does not attempt to do anything too silly and will have guards around code that depends on being run from a terminal.
If this is the entirety of the script, then the TERM
error is coming from something other than the plain content of the script.
It sounds like you're using an incorrect address:
To access the Service I enter http://localhost/project/myService.svc/FileUpload
Assuming you mean this is the address you give your client code then I suspect it should actually be:
http://localhost/project/myService.svc
To remove the optional you only should do this
println("\(text2!)")
cause if you dont use "!" it takes the optional value of text2
And to remove "" from 5 you have to convert it to NSInteger or NSNumber easy peasy. It has "" cause its an string.
For those wanting to do a JOIN that updates ONLY the rows your join returns use:
UPDATE a
SET price = b_alias.unit_price
FROM a AS a_alias
LEFT JOIN b AS b_alias ON a_alias.b_fk = b_alias.id
WHERE a_alias.unit_name LIKE 'some_value'
AND a.id = a_alias.id
--the below line is critical for updating ONLY joined rows
AND a.pk_id = a_alias.pk_id;
This was mentioned above but only through a comment..Since it's critical to getting the correct result posting NEW answer that Works
I'm going to assume you are using Web Site Projects. These automatically crawl their project directory and throw everything into source control. There's no way to stop them.
However, don't despair. Web Application Projects don't exhibit this strange and rather unexpected (imho: moronic) behavior. WAP is an addon on for VS2005 and comes direct with VS2008.
As an alternative to changing your projects to WAP, you might consider moving the Assets folder out of Source control and into a TFS Document Library. Only do this IF the project itself doesn't directly use the assets files.
In my case it was a table with an ENUM that accepts the days of the week as integers (0 to 6). When inserting the value 0 as an integer I got the error message "Data truncated for column ..." so to fix it I had to cast the integer to a string. So instead of:
$item->day = 0;
I had to do;
$item->day = (string) 0;
It looks silly to cast the zero like that but in my case it was in a Laravel factory, and I had to write it like this:
$factory->define(App\Schedule::class, function (Faker $faker) {
return [
'day' => (string) $faker->numberBetween(0, 6),
//
];
});
Simple Steps:
-Open Eclipse.
To be able to inspect any element do the following. This should work even if it's hard to duplicate the hover state:
Run the following javascript in the console. This will break into the debugger in 5 seconds.
setTimeout(function(){debugger;}, 5000)
Go show your element (by hovering or however) and wait until Chrome breaks into the Debugger.
Elements
tab in the Chrome Inspector, and you can look for your element there. Find Element
icon (looks like a magnifying glass) and Chrome will let you go and inspect and find your element on the page by right clicking on it, then choosing Inspect Element
Note that this approach is a slight variation to this other great answer on this page.
Java 6 has a default embedded http server.
By the way, if you plan to have a rest web service, here is a simple example using jersey.
Set proper constraint and update delegate methods as:
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return UITableViewAutomaticDimension
}
func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
return UITableViewAutomaticDimension
}
This will resolve dynamic cell height issue. IF not you need to check constraints.
Try this
$servers = Get-Content test.txt
$reg=""
foreach ($server in $servers)
{
$reg=$reg+$server+"`t"+([System.Net.Dns]::GetHostAddresses($server) | foreach {echo $_.IPAddressToString})+"`n"
}
$reg >reg.csv
In swift you can subclass NSView and do this
class MyView:NSView {
required init?(coder: NSCoder) {
super.init(coder: coder);
self.wantsLayer = true;
self.layer?.backgroundColor = NSColor.redColor().CGColor;
}
}
// Get the focused element:
var $focused = $(':focus');
// No jQuery:
var focused = document.activeElement;
// Does the element have focus:
var hasFocus = $('foo').is(':focus');
// No jQuery:
elem === elem.ownerDocument.activeElement;
Which one should you use? quoting the jQuery docs:
As with other pseudo-class selectors (those that begin with a ":"), it is recommended to precede :focus with a tag name or some other selector; otherwise, the universal selector ("*") is implied. In other words, the bare
$(':focus')
is equivalent to$('*:focus')
. If you are looking for the currently focused element, $( document.activeElement ) will retrieve it without having to search the whole DOM tree.
The answer is:
document.activeElement
And if you want a jQuery object wrapping the element:
$(document.activeElement)
Example
//In Model
public class MyModel
{
[Required]
public string Name{ get; set; }
}
//In PartailView //PartailView.cshtml
@model MyModel
<div>
<div>
@Html.LabelFor(model=>model.Name)
</div>
<div>
@Html.EditorFor(model=>model.Name)
@Html.ValidationMessageFor(model => model.Name)
</div>
</div>
In Index.cshtml view
@model MyModel
<div id="targetId">
@{Html.RenderPartial("PartialView",Model)}
</div>
@using(Ajax.BeginForm("AddName", new AjaxOptions { UpdateTargetId = "targetId", HttpMethod = "Post" }))
{
<div>
<input type="submit" value="Add Unit" />
</div>
}
In Controller
public ActionResult Index()
{
return View(new MyModel());
}
public string AddName(MyModel model)
{
string HtmlString = RenderPartialViewToString("PartailView",model);
return HtmlString;
}
protected string RenderPartialViewToString(string viewName, object model)
{
if (string.IsNullOrEmpty(viewName))
viewName = ControllerContext.RouteData.GetRequiredString("action");
ViewData.Model = model;
using (StringWriter sw = new StringWriter())
{
ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(ControllerContext, viewName);
ViewContext viewContext = new ViewContext(ControllerContext, viewResult.View, ViewData, TempData, sw);
viewResult.View.Render(viewContext, sw);
return sw.GetStringBuilder().ToString();
}
}
you must be pass ViewName and Model to RenderPartialViewToString method. it will return you view with validation which are you applied in model and append the content in "targetId" div in Index.cshtml. I this way by catching RenderHtml of partial view you can apply validation.
There is nothing you can do on your end (client side). You can not enable crossDomain calls yourself, the source (dailymotion.com) needs to have CORS enabled for this to work.
The only thing you can really do is to create a server side proxy script which does this for you. Are you using any server side scripts in your project? PHP, Python, ASP.NET etc? If so, you could create a server side "proxy" script which makes the HTTP call to dailymotion and returns the response. Then you call that script from your Javascript code, since that server side script is on the same domain as your script code, CORS will not be a problem.
The reason why it's probably a bad idea to start building your own highlighting function from scratch is because you will certainly run into issues that others have already solved. Challenges:
innerHTML
)Sounds complicated? If you want some features like ignoring some elements from highlighting, diacritics mapping, synonyms mapping, search inside iframes, separated word search, etc. this becomes more and more complicated.
When using an existing, well implemented plugin, you don't have to worry about above named things. The article 10 jQuery text highlighter plugins on Sitepoint compares popular highlighter plugins.
mark.js is such a plugin that is written in pure JavaScript, but is also available as jQuery plugin. It was developed to offer more opportunities than the other plugins with options to:
Alternatively you can see this fiddle.
Usage example:
// Highlight "keyword" in the specified context
$(".context").mark("keyword");
// Highlight the custom regular expression in the specified context
$(".context").markRegExp(/Lorem/gmi);
It's free and developed open-source on GitHub (project reference).

There's a great deal of research on this. Here's a quick summary.
Response Times: The 3 Important Limits
by Jakob Nielsen on January 1, 1993
Summary: There are 3 main time limits (which are determined by human perceptual abilities) to keep in mind when optimizing web and application performance.
Excerpt from Chapter 5 in my book Usability Engineering, from 1993:
The basic advice regarding response times has been about the same for thirty years [Miller 1968; Card et al. 1991]:
- 0.1 second is about the limit for having the user feel that the system is reacting instantaneously, meaning that no special feedback is necessary except to display the result.
- 1.0 second is about the limit for the user's flow of thought to stay uninterrupted, even though the user will notice the delay. Normally, no special feedback is necessary during delays of more than 0.1 but less than 1.0 second, but the user does lose the feeling of operating directly on the data.
- 10 seconds is about the limit for keeping the user's attention focused on the dialogue. For longer delays, users will want to perform other tasks while waiting for the computer to finish, so they should be given feedback indicating when the computer expects to be done. Feedback during the delay is especially important if the response time is likely to be highly variable, since users will then not know what to expect.
This is how I handle it.
window.open(doc.output('bloburl'), '_blank');
Since you did not mention which version of Turbo C this method below will cover both v2 and v3.
An alternative to already mentioned tools is Telerik JustDecompile (free tool) which will display the information next to the assembly name:
little complete sample:
using System.ComponentModel;
private bool bShowGroup ;
[Description("Show the group table"), Category("Sea"),DefaultValue(true)]
public bool ShowGroup
{
get { return bShowGroup; }
set { bShowGroup = value; }
}
When to use a heap and when to use a BST
Heap is better at findMin/findMax (O(1)
), while BST is good at all finds (O(logN)
). Insert is O(logN)
for both structures. If you only care about findMin/findMax (e.g. priority-related), go with heap. If you want everything sorted, go with BST.
First few slides from here explain things very clearly.
In this case you could use basename assuming you have the same suffix on the files you want to remove.
Example:
basename -s .rtf "some string.rtf"
This will return "some string"
If you don't know the suffix, and want it to remove everything after and including the last dot:
f=file.whateverthisis
basename "${f%.*}"
outputs "file"
% means chop, . is what you are chopping, * is wildcard
If you want to filter rows by a certain number of columns with null values, you may use this:
df.iloc[df[(df.isnull().sum(axis=1) >= qty_of_nuls)].index]
So, here is the example:
Your dataframe:
>>> df = pd.DataFrame([range(4), [0, np.NaN, 0, np.NaN], [0, 0, np.NaN, 0], range(4), [np.NaN, 0, np.NaN, np.NaN]])
>>> df
0 1 2 3
0 0.0 1.0 2.0 3.0
1 0.0 NaN 0.0 NaN
2 0.0 0.0 NaN 0.0
3 0.0 1.0 2.0 3.0
4 NaN 0.0 NaN NaN
If you want to select the rows that have two or more columns with null value, you run the following:
>>> qty_of_nuls = 2
>>> df.iloc[df[(df.isnull().sum(axis=1) >=qty_of_nuls)].index]
0 1 2 3
1 0.0 NaN 0.0 NaN
4 NaN 0.0 NaN NaN
If you're in local machine then use this command
/usr/local/mysql/bin/mysqldump -h127.0.0.1 --port = 3306 -u [username] -p [password] --databases [db_name] --tables [tablename] > /to/path/tablename.sql;
For remote machine, use below one
/usr/local/mysql/bin/mysqldump -h [remoteip] --port = 3306 -u [username] -p [password] --databases [db_name] --tables [tablename] > /to/path/tablename.sql;
Yes, you can install an interrupt handler using the module signal, and wait forever using a threading.Event:
import signal
import sys
import time
import threading
def signal_handler(signal, frame):
print('You pressed Ctrl+C!')
sys.exit(0)
signal.signal(signal.SIGINT, signal_handler)
print('Press Ctrl+C')
forever = threading.Event()
forever.wait()
Just add an OR in the conditions
Model.find(:all, :conditions => ["column = ? OR other_column = ?",value, other_value])
Spring Docs explain that
In proxy mode (which is the default), only external method calls coming in through the proxy are intercepted. This means that self-invocation, in effect, a method within the target object calling another method of the target object, will not lead to an actual transaction at runtime even if the invoked method is marked with @Transactional.
Consider the use of AspectJ mode (see mode attribute in table below) if you expect self-invocations to be wrapped with transactions as well. In this case, there will not be a proxy in the first place; instead, the target class will be weaved (that is, its byte code will be modified) in order to turn @Transactional into runtime behavior on any kind of method.
Another way is user BeanSelfAware
In the scenario you would NOT like to use the onChange handler on the input DOM, you can use the onClick
property as an alternative. The defaultChecked
, the condition may leave a fixed state for v16 IINM.
class CrossOutCheckbox extends Component {
constructor(init){
super(init);
this.handleChange = this.handleChange.bind(this);
}
handleChange({target}){
if (target.checked){
target.removeAttribute('checked');
target.parentNode.style.textDecoration = "";
} else {
target.setAttribute('checked', true);
target.parentNode.style.textDecoration = "line-through";
}
}
render(){
return (
<span>
<label style={{textDecoration: this.props.complete?"line-through":""}}>
<input type="checkbox"
onClick={this.handleChange}
defaultChecked={this.props.complete}
/>
</label>
{this.props.text}
</span>
)
}
}
I hope this helps someone in the future.
You can implement two tic()
and tac()
functions, where tic()
captures the time which it is called, and tac()
prints the time difference since tic()
was called. Here is a short implementation:
import time
_start_time = time.time()
def tic():
global _start_time
_start_time = time.time()
def tac():
t_sec = round(time.time() - _start_time)
(t_min, t_sec) = divmod(t_sec,60)
(t_hour,t_min) = divmod(t_min,60)
print('Time passed: {}hour:{}min:{}sec'.format(t_hour,t_min,t_sec))
Now in your code you can use it as:
tic()
do_some_stuff()
tac()
and it will, for example, output:
Time passed: 0hour:7min:26sec
I would to it like this:
//Dictionary object with Key as string and Value as List of Component type object
Dictionary<String, List<Component>> dic = new Dictionary<String, List<Component>>();
//from each element of the dictionary select first component if any
IEnumerable<Component> components = dic.Where(kvp => kvp.Value.Any()).Select(kvp => (kvp.Value.First() as Component).ComponentValue("Dep"));
but only if it is sure that list contains only objects of Component class or children
If this error appears whenever you click on the <a>

CORRECT :
<a href="javascript:void(0)">
This malfunction occurs because your href is set to # inside of your <a>

WRONG :

ADO Recordset has .State
property, you can check if its value is adStateClosed
or adStateOpen
If Not (rs Is Nothing) Then
If (rs.State And adStateOpen) = adStateOpen Then rs.Close
Set rs = Nothing
End If
Edit;
The reason not to check .State
against 1 or 0 is because even if it works 99.99% of the time, it is still possible to have other flags set which will cause the If statement fail the adStateOpen
check.
Edit2:
For Late binding without the ActiveX Data Objects referenced, you have few options. Use the value of adStateOpen constant from ObjectStateEnum
If Not (rs Is Nothing) Then
If (rs.State And 1) = 1 Then rs.Close
Set rs = Nothing
End If
Or you can define the constant yourself to make your code more readable (defining them all for a good example.)
Const adStateClosed As Long = 0 'Indicates that the object is closed.
Const adStateOpen As Long = 1 'Indicates that the object is open.
Const adStateConnecting As Long = 2 'Indicates that the object is connecting.
Const adStateExecuting As Long = 4 'Indicates that the object is executing a command.
Const adStateFetching As Long = 8 'Indicates that the rows of the object are being retrieved.
[...]
If Not (rs Is Nothing) Then
' ex. If (0001 And 0001) = 0001 (only open flag) -> true
' ex. If (1001 And 0001) = 0001 (open and retrieve) -> true
' This second example means it is open, but its value is not 1
' and If rs.State = 1 -> false, even though it is open
If (rs.State And adStateOpen) = adStateOpen Then
rs.Close
End If
Set rs = Nothing
End If
Try starting the project using the python_boilerplate template. It largely follows the best practices (e.g. those here), but is better suited in case you find yourself willing to split your project into more than one egg at some point (and believe me, with anything but the simplest projects, you will. One common situation is where you have to use a locally-modified version of someone else's library).
Where do you put the source?
PROJECT_ROOT/src/<egg_name>
.Where do you put application startup scripts?
entry_point
in one of the eggs.Where do you put the IDE project cruft?
PROJECT_ROOT/.<something>
in the root of the project, and this is fine.Where do you put the unit/acceptance tests?
PROJECT_ROOT/src/<egg_name>/tests
directory. I personally prefer to use py.test
to run them.Where do you put non-Python data such as config files?
pkg_resources
package from setuptools
, or since Python 3.7 via the importlib.resources
module from the standard library.PROJECT_ROOT/config
. For deployment there can be various options. On Windows one can use %APP_DATA%/<app-name>/config
, on Linux, /etc/<app-name>
or /opt/<app-name>/config
.PROJECT_ROOT/var
during development, and under /var
during Linux deployment.PROJECT_ROOT/src/<egg_name>/native
Documentation would typically go into PROJECT_ROOT/doc
or PROJECT_ROOT/src/<egg_name>/doc
(this depends on whether you regard some of the eggs to be a separate large projects). Some additional configuration will be in files like PROJECT_ROOT/buildout.cfg
and PROJECT_ROOT/setup.cfg
.

If the usage of something is part of the process of you making money, then it's generally considered a commercial use. If the purpose of the site is to, through some means or another, directly or indirectly, make you money, then it's probably commercial use.
If, on the other hand, something is merely incidental (not part of the process of production/working, but instead simply tacked on to the side), there are potential grounds for it not to be considered commercial use.

You can iterate over "a file", which produces lines, including the trailing newline character. To make a "virtual file" out of a string, you can use StringIO
:
import io # for Py2.7 that would be import cStringIO as io
for line in io.StringIO(foo):
print(repr(line))
Utilize String.format
's padding with spaces and replace them with the desired char.
String toPad = "Apple";
String padded = String.format("%8s", toPad).replace(' ', '0');
System.out.println(padded);
Prints 000Apple
.
Update more performant version (since it does not rely on String.format
), that has no problem with spaces (thx to Rafael Borja for the hint).
int width = 10;
char fill = '0';
String toPad = "New York";
String padded = new String(new char[width - toPad.length()]).replace('\0', fill) + toPad;
System.out.println(padded);
Prints 00New York
.
But a check needs to be added to prevent the attempt of creating a char array with negative length.

Most of the time I use the following command to achieve a complete reinstall of all the node modules (be sure you are in the project folder).
rm -rf node_modules && npm install
You can also run npm cache clean
after removing the node_modules
folder to be sure there aren't any cached dependencies.
I have found a blog article by Deborah Kurata with a nice trick how to show variable number of columns in a DataGrid:
Populating a DataGrid with Dynamic Columns in a Silverlight Application using MVVM
Basically, she creates a DataGridTemplateColumn
and puts ItemsControl
inside that displays multiple columns.
@victor hugo and @unwind are correct, and victor's solution is by far the simplest. However BEWARE of externals in your SVN project. If you reference external libraries, the external's revision reference (whether a tag, or HEAD, or number) will remain unchanged when you tag directories that have external references.
It is possible to create a script to handle this aspect of tagging, for a discussion on that topic, see this SO article: Tagging an SVN checkout with externals
I would avoid now using /// <reference path='moo.ts'/>
but for external libraries where the definition file is not included into the package.
The reference path
solves errors in the editor, but it does not really means the file needs to be imported. Therefore if you are using a gulp workflow or JSPM, those might try to compile separately each file instead of tsc -out
to one file.
From Typescript 1.5
Just prefix what you want to export at the file level (root scope)
aLib.ts
{
export class AClass(){} // exported i.e. will be available for import
export valueZero = 0; // will be available for import
}
You can also add later in the end of the file what you want to export
{
class AClass(){} // not exported yet
valueZero = 0; // not exported yet
valueOne = 1; // not exported (and will not in this example)
export {AClass, valueZero} // pick the one you want to export
}
Or even mix both together
{
class AClass(){} // not exported yet
export valueZero = 0; // will be available for import
export {AClass} // add AClass to the export list
}
For the import you have 2 options, first you pick again what you want (one by one)
anotherFile.ts
{
import {AClass} from "./aLib.ts"; // you import only AClass
var test = new AClass();
}
Or the whole exports
{
import * as lib from "./aLib.ts"; // you import all the exported values within a "lib" object
var test = new lib.AClass();
}
Note regarding the exports: exporting twice the same value will raise an error { export valueZero = 0; export {valueZero}; // valueZero is already exported… }
You have not specified the version, I'm assuming you are using Powershell v3.
Try this:
$path = "C:\Users\abc\Desktop\File\abc.txt"
(Get-Content $path -Raw).Replace("`r`n","`n") | Set-Content $path -Force
Editor's note: As mike z points out in the comments, Set-Content
appends a trailing CRLF, which is undesired. Verify with: 'hi' > t.txt; (Get-Content -Raw t.txt).Replace("`r`n","`n") | Set-Content t.txt; (Get-Content -Raw t.txt).EndsWith("`r`n")
, which yields $True
.
Note this loads the whole file in memory, so you might want a different solution if you want to process huge files.
UPDATE
This might work for v2 (sorry nowhere to test):
$in = "C:\Users\abc\Desktop\File\abc.txt"
$out = "C:\Users\abc\Desktop\File\abc-out.txt"
(Get-Content $in) -join "`n" > $out
Editor's note: Note that this solution (now) writes to a different file and is therefore not equivalent to the (still flawed) v3 solution. (A different file is targeted to avoid the pitfall Ansgar Wiechers points out in the comments: using >
truncates the target file before execution begins). More importantly, though: this solution too appends a trailing CRLF, which may be undesired. Verify with 'hi' > t.txt; (Get-Content t.txt) -join "`n" > t.NEW.txt; [io.file]::ReadAllText((Convert-Path t.NEW.txt)).endswith("`r`n")
, which yields $True
.
Same reservation about being loaded to memory though.
An easy solution, but not the proper way is to use raw SQL:
results = Members.objects.raw('SELECT * FROM myapp_members GROUP BY designation')
Another solution is to use the group_by
property:
query = Members.objects.all().query
query.group_by = ['designation']
results = QuerySet(query=query, model=Members)
You can now iterate over the results variable to retrieve your results. Note that group_by
is not documented and may be changed in future version of Django.
And... why do you want to use group_by
? If you don't use aggregation, you can use order_by
to achieve an alike result.
A similar approach to @Peter Coppins answer. This, I think, is a bit easier and doesn't require the use of the Orca utility:
Check the "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\14.0\Common\FilesPaths" registry key and make sure the value "mso.dll" is NOT present. If it is present, then Office 64-bit seems to be installed and you should not need this workaround.
Download the Microsoft Access Database Engine 2010 Redistributable.
From the command line, run: AccessDatabaseEngine_x64.exe /passive
(Note: this installer silently crashed or failed for me, so I unzipped the components and ran: AceRedist.msi /passive and that installed fine. Maybe a Windows 10 thing.)

CURRENT_TIMESTAMP
is only acceptable on TIMESTAMP
fields. DATETIME
fields must be left either with a null default value, or no default value at all - default values must be a constant value, not the result of an expression.

You can work around this by setting a post-insert trigger on the table to fill in a "now" value on any new records.
Yes, there is a problem with pointers. Very likely you're using one that's not initialized properly, but it's also possible that you're messing up your memory management with double frees or some such.
To avoid uninitialized pointers as local variables, try declaring them as late as possible, preferably (and this isn't always possible) when they can be initialized with a meaningful value. Convince yourself that they will have a value before they're being used, by examining the code. If you have difficulty with that, initialize them to a null pointer constant (usually written as NULL
or 0
) and check them.
To avoid uninitialized pointers as member values, make sure they're initialized properly in the constructor, and handled properly in copy constructors and assignment operators. Don't rely on an init
function for memory management, although you can for other initialization.
If your class doesn't need copy constructors or assignment operators, you can declare them as private member functions and never define them. That will cause a compiler error if they're explicitly or implicitly used.
Use smart pointers when applicable. The big advantage here is that, if you stick to them and use them consistently, you can completely avoid writing delete
and nothing will be double-deleted.
Use C++ strings and container classes whenever possible, instead of C-style strings and arrays. Consider using .at(i)
rather than [i]
, because that will force bounds checking. See if your compiler or library can be set to check bounds on [i]
, at least in debug mode. Segmentation faults can be caused by buffer overruns that write garbage over perfectly good pointers.
Doing those things will considerably reduce the likelihood of segmentation faults and other memory problems. They will doubtless fail to fix everything, and that's why you should use valgrind now and then when you don't have problems, and valgrind and gdb when you do.
You should run:
composer dump-autoload
and if does not work you should:
re-install composer
You didn't say which database server you are using, but if temp tables are available they may be the best approach.
// table is a temp table
select ... into #table ....
SELECT COUNT(column1),column1 FROM #table GROUP BY column1
SELECT COUNT(column2),column2 FROM #table GROUP BY column2
SELECT COUNT(column3),column3 FROM #table GROUP BY column3
// drop may not be required
drop table #table
None is used to indicate "not set", whereas any other value is used to indicate a "default" value.
Hence, if your class copes with empty strings and you like it as a default value, use "". If your class needs to check if the variable was set at all, use None.
Notice that it doesn't matter if your variable is a string initially. You can change it to any other type/value at any other moment.
Sprint == Iteration.
The lengths can vary, but it's a bad planning precedent to let them vary too much.
Keep them consistent in duration and you will get better at planning and delivering. Everything will be measured by how many 10-day sprints it takes to finish a series of use cases.
Keep them consistent in length and you can plan your deliveries, end-user testing, etc., with more accuracy.
The point is to release on time at a consistent pace. A regular schedule makes management slightly simpler and more predictable.
Ran into the same thing trying to install brew's python3 under Mac OS! The issue here is that in Mac OS, homebrew puts the "real" python a whole layer deeper than you think. You would think from the homebrew output that
$ echo $PYTHONHOME
/usr/local/Cellar/python3/3.6.2/
$ echo $PYTHONPATH
/usr/local/Cellar/python3/3.6.2/bin
would be correct, but invoking $PYTHONPATH/python3 immediately crashes with the abort 6 "can't find encodings." This is because although that $PYTHONHOME looks like a complete installation, having a bin, lib etc, it is NOT the actual Python, which is in a Mac OS "Framework". Do this:
PYTHONHOME=/usr/local/Cellar/python3/3.x.y/Frameworks/Python.framework/Versions/3.x
PYTHONPATH=$PYTHONHOME/bin
(substituting version numbers as appropriate) and it will work fine.
pdfName.split("[.-]+");

Links with href="#" should almost always be replaced with a button element:
<button class="someclass">Text</button>
Using links with href="#" is also an accessibility concern as these links will be visible to screen readers, which will read out "Link - Text" but if the user clicks it won't go anywhere.

As already mentioned, tern.js is a new and promising project with plugins for Sublime Text, Vim and Emacs. I´ve been using TernJS for Sublime for a while and the suggestions I get are way better than the standard ones:
Tern scans all .js files in your project. You can get support for DOM, nodejs, jQuery, and more by adding "libs" in your .sublime-project file:
"ternjs": {
"exclude": ["wordpress/**", "node_modules/**"],
"libs": ["browser", "jquery"],
"plugins": {
"requirejs": {
"baseURL": "./js"
}
}
}
You could create Util class:
public final class CollectionHelpers {
public static <T> boolean addNullSafe(List<T> list, T element) {
if (list == null || element == null) {
return false;
}
return list.add(element);
}
}
And then use it:
Element element = getElementFromSomeWhere(someParameter);
List<Element> arrayList = new ArrayList<>();
CollectionHelpers.addNullSafe(list, element);
Here's a list of keycodes that includes a way to look them up interactively.
Java doesn't want you to make an array of HashMaps, but it will let you make an array of Objects. So, just write up a class declaration as a shell around your HashMap, and make an array of that class. This lets you store some extra data about the HashMaps if you so choose--which can be a benefit, given that you already have a somewhat complex data structure.
What this looks like:
private static someClass[] arr = new someClass[someNum];
and
public class someClass {
private static int dataFoo;
private static int dataBar;
private static HashMap<String, String> yourArray;
...
}
Another option is to run the two inserts separately, leaving the FK column null, then running an update to poulate it correctly.
If there is nothing natural stored within the two tables that match from one record to another (likely) then create a temporary GUID column and populate this in your data and insert to both fields. Then you can update with the proper FK and null out the GUIDs.
E.g.:
CREATE TABLE [dbo].[table1] (
[id] [int] IDENTITY(1,1) NOT NULL,
[data] [varchar](255) NOT NULL,
CONSTRAINT [PK_table1] PRIMARY KEY CLUSTERED ([id] ASC),
JoinGuid UniqueIdentifier NULL
)
CREATE TABLE [dbo].[table2] (
[id] [int] IDENTITY(1,1) NOT NULL,
[table1_id] [int] NULL,
[data] [varchar](255) NOT NULL,
CONSTRAINT [PK_table2] PRIMARY KEY CLUSTERED ([id] ASC),
JoinGuid UniqueIdentifier NULL
)
INSERT INTO Table1....
INSERT INTO Table2....
UPDATE b
SET table1_id = a.id
FROM Table1 a
JOIN Table2 b on a.JoinGuid = b.JoinGuid
WHERE b.table1_id IS NULL
UPDATE Table1 SET JoinGuid = NULL
UPDATE Table2 SET JoinGuid = NULL
Thanks @Mark, I keep forgetting this again and again. After installing MongoDB with Homebrew:
Use ng-show
and toggle the value of a show
scope variable in the ng-click
handler.
Here is a working example: http://jsfiddle.net/pvtpenguin/wD7gR/1/
<ul class="procedures">
<li ng-repeat="procedure in procedures">
<h4><a href="#" ng-click="show = !show">{{procedure.definition}}</a></h4>
<div class="procedure-details" ng-show="show">
<p>Number of patient discharges: {{procedure.discharges}}</p>
<p>Average amount covered by Medicare: {{procedure.covered}}</p>
<p>Average total payments: {{procedure.payments}}</p>
</div>
</li>
</ul>
At first you should create constructor like this
constructor(props) {
super(props);
this.state = {
close: true,
};
}
yourFunction = () => {
this.setState({
close: !this.state.close,
});
};
then use this like
render() {
const {close} = this.state;
return (
<Fragment>
<div onClick={() => this.yourFunction()}></div>
<div className={close ? "isYourDefaultClass" : "isYourOnChangeClass"}></div>
</Fragment>
)
}
}

AndroidX is the open-source project that the Android team uses to develop, test, package, version and release libraries within Jetpack.
After hours of struggling, I solved it by including the following within app/build.gradle:
android {
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
Put these flags in your gradle.properties
android.enableJetifier=true
android.useAndroidX=true

implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation 'androidx.legacy:legacy-support-v4:1.0.0'
implementation 'com.google.android.material:material:1.1.0-alpha04'

Another one is to use wrapper objects. You don't need to write them yourself as google already provides them:
At the top of your .proto file add this import:
import "google/protobuf/wrappers.proto";
Now you can use special wrappers for every simple type:
DoubleValue
FloatValue
Int64Value
UInt64Value
Int32Value
UInt32Value
BoolValue
StringValue
BytesValue
So to answer the original question a usage of such a wrapper could be like this:
message Foo {
int32 bar = 1;
google.protobuf.Int32Value baz = 2;
}
Now for example in Java I can do stuff like:
if(foo.hasBaz()) { ... }
FYI: If you have bootstrap.js, you should not add bootstrap-dropdown.js.
I'm unsure of the result with bootstrap.min.js.
They are equivalent, from the standard (emphasis mine) (7.1.3.2):
A typedef-name can also be introduced by an alias-declaration. The identifier following the using keyword becomes a typedef-name and the optional attribute-specifier-seq following the identifier appertains to that typedef-name. It has the same semantics as if it were introduced by the typedef specifier. In particular, it does not define a new type and it shall not appear in the type-id.
You want to use slicing.
for item in listOfStuff[1:3]:
print item
Don't want to be repetitive, but just to summarize in other way (features added in new HttpClient):
I wrote an article, where I covered the difference between old "http" and new "HttpClient". The goal was to explain it in the easiest way possible.
Using HttpClient (Http's replacement) in Angular 4.3+, the entire mapping/casting process is made simpler/eliminated.
Using your CountryData class, you would define a service method like this:
getCountries() {
return this.httpClient.get<CountryData[]>('http://theUrl.com/all');
}
Then when you need it, define an array like this:
countries:CountryData[] = [];
and subscribe to it like this:
this.countryService.getCountries().subscribe(countries => this.countries = countries);
A complete setup answer is posted here also.

SOAP
Simple Object Access Protocol (SOAP) is a standard, an XML language, defining a message architecture and message formats. It is used by Web services. It contains a description of the operations.
WSDL is an XML-based language for describing Web services and how to access them. It will run on SMTP, HTTP, FTP, etc. It requires middleware support and well-defined mechanism to define services like WSDL+XSD and WS-Policy. SOAP will return XML based data
REST
Representational State Transfer (RESTful) web services. They are second-generation Web services.
RESTful web services communicate via HTTP rather than SOAP-based services and do not require XML messages or WSDL service-API definitions. For REST middleware is not required, only HTTP support is needed. It is a WADL standard, REST can return XML, plain text, JSON, HTML, etc.

constructor(props) {
super(props);
this.onMove = this.onMove.bind(this);
this.test = "this is a test";
}
onMove() {
console.log(this.test);
}
}
Also, test !== testVariable
.
in this code data
is a two dimensional array of table data
let oTable = document.getElementById('datatable-id');
let data = [...oTable.rows].map(t => [...t.children].map(u => u.innerText))
I don't believe the expression is sensical as it is.
Elvis means "if truthy, use the value, else use this other thing."
Your "other thing" is a closure, and the value is status != null
, neither of which would seem to be what you want. If status
is null, Elvis says true
. If it's not, you get an extra layer of closure.
Why can't you just use:
(it.description == desc) && ((status == null) || (it.status == status))
Even if that didn't work, all you need is the closure to return the appropriate value, right? There's no need to create two separate find
calls, just use an intermediate variable.
Put the things like /src/main/resources/foo/bar.properties
and then reference them as classpath:/foo/bar.properties
.
CREATE TABLE newTable LIKE oldTable;
Then, to copy the data over
INSERT INTO newTable SELECT * FROM oldTable;
Simply :
$(".leaderMultiSelctdropdown").val()
setTimeout(function () { location.reload(1); }, 5000);
But as development tools go, you are probably better off with https://addons.mozilla.org/en-US/firefox/addon/115
As explained in the previous answer it provides a simple interface to the consuming client. For example: "watch ESPN" is the intended function. But it involves several steps like:
But the facade will simplify this and just provide "watch ESPN" function to the client.
"Day of Week" is actually something you can get directly from the php date() function with the format "l" or "N" respectively. Have a look at the manual
edit: Sorry I didn't read the posts of Kalium properly, he already explained that. My bad.
Code

(default Ctrl + Alt + L) for the whole file or Code
? Auto-Indent Lines
(default Ctrl + Alt + I) for the current line or selection.
You can customise the settings for how code is auto-formatted under File

? Code Style
.
To ensure comments are also indented to the same level as the code, you can simply do as follows:
This should help you get rid of body margins and default top margin of <h1>
tag
body{
margin: 0px;
padding: 0px;
}
h1 {
margin-top: 0px;
