I prefer this solution using the csv
module from the standard library and the with
statement to avoid leaving the file open.
The key point is using 'a'
for appending when you open the file.
import csv
fields=['first','second','third']
with open(r'name', 'a') as f:
writer = csv.writer(f)
writer.writerow(fields)
If you are using Python 2.7 you may experience superfluous new lines in Windows. You can try to avoid them using 'ab'
instead of 'a'
this will, however, cause you TypeError: a bytes-like object is required, not 'str' in python and CSV in Python 3.6. Adding the newline=''
, as Natacha suggests, will cause you a backward incompatibility between Python 2 and 3.
I found a very basic example of List comparison at List Compare This example verifies the size first and then checks the availability of the particular element of one list in another.
There's a lot of great - complex - answers here. In my particular case i found a clean and simple fix for the logout. I have yet to test in Edge. On my page that I have logged in to, I have placed a logout link similar to this:
<a href="https://MyDomainHere.net/logout.html">logout</a>
And in the head of that logout.html page (which is also protected by the .htaccess) I have a page refresh similar to this:
<meta http-equiv="Refresh" content="0; url=https://logout:[email protected]/" />
Where you would leave the words "logout" in place to clear the username and password cached for the site.
I will admit that if multiple pages needed to be able to be directly logged in to from the beginning, each of those points of entry would need their own corresponding logout.html page. Otherwise you could centralize the logout by introducing an additional gatekeeper step into the process before the actual login prompt, requiring entry of a phrase to reach a destination of login.
SymmetricDS is the answer. It supports multiple subscribers with one direction or bi-directional asynchronous data replication. It uses web and database technologies to replicate tables between relational databases, in near real time if desired.
Comprehensive and robust Java API to suit your needs.
I think it is good for you.
BigDecimal.valueOf([LONG_VALUE]).doubleValue()
How about this code? :D
Basically it checks if the value before the || evaluates to true, if yes, it takes this value, if not, it takes the value after the ||.
Values for which it will take the value after the || (as far as i remember):
It will fail to work when:
You are redirecting the response to a new request by response.sendRedirect("page.jsp")
. The newly created request object will of course not contain the attributes anymore and they will not be accessible in the redirected JSP. You need to forward rather than redirect. E.g.
request.setAttribute("name", "value");
request.getRequestDispatcher("page.jsp").forward(request, response);
You are accessing it the wrong way or using the wrong name. Assuming that you have set it using the name "name"
, then you should be able to access it in the forwarded JSP page as follows:
${name}
Another candidate solution using a regex. Retains token order, correctly matches multiple tokens of the same type in a row. The downside is that the regex is kind of nasty.
package javaapplication2;
import java.util.ArrayList;
import java.util.List;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class JavaApplication2 {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
String num = "58.5+variable-+98*78/96+a/78.7-3443*12-3";
// Terrifying regex:
// (a)|(b)|(c) match a or b or c
// where
// (a) is one or more digits optionally followed by a decimal point
// followed by one or more digits: (\d+(\.\d+)?)
// (b) is one of the set + * / - occurring once: ([+*/-])
// (c) is a sequence of one or more lowercase latin letter: ([a-z]+)
Pattern tokenPattern = Pattern.compile("(\\d+(\\.\\d+)?)|([+*/-])|([a-z]+)");
Matcher tokenMatcher = tokenPattern.matcher(num);
List<String> tokens = new ArrayList<>();
while (!tokenMatcher.hitEnd()) {
if (tokenMatcher.find()) {
tokens.add(tokenMatcher.group());
} else {
// report error
break;
}
}
System.out.println(tokens);
}
}
Sample output:
[58.5, +, variable, -, +, 98, *, 78, /, 96, +, a, /, 78.7, -, 3443, *, 12, -, 3]
The low-level way would be to access the matrix data directly. In an RGB image (which I believe OpenCV typically stores as BGR), and assuming your cv::Mat variable is called frame
, you could get the blue value at location (x
, y
) (from the top left) this way:
frame.data[frame.channels()*(frame.cols*y + x)];
Likewise, to get B, G, and R:
uchar b = frame.data[frame.channels()*(frame.cols*y + x) + 0];
uchar g = frame.data[frame.channels()*(frame.cols*y + x) + 1];
uchar r = frame.data[frame.channels()*(frame.cols*y + x) + 2];
Note that this code assumes the stride is equal to the width of the image.
Seem like the input
type number
does not support size
attribute or it's not compatible along browsers, you can set it through CSS instead:
input[type=number]{
width: 80px;
}
If you are doing what I believe you are trying to do, you'll need something a little more like this:
table {
border-collapse: collapse;
}
table td, table th {
border: 1px solid black;
}
table tr:first-child th {
border-top: 0;
}
table tr:last-child td {
border-bottom: 0;
}
table tr td:first-child,
table tr th:first-child {
border-left: 0;
}
table tr td:last-child,
table tr th:last-child {
border-right: 0;
}
The problem is that you are setting a 'full border' around all the cells, which make it appear as if you have a border around the entire table.
Cheers.
EDIT: A little more info on those pseudo-classes can be found on quirksmode, and, as to be expected, you are pretty much S.O.L. in terms of IE support.
I know this is a pretty old question but this was my solution that helped with visualizing the table so you can create a class structure. This is also using the HTML Agility Pack
HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(@"<html><body><p><table id=""foo""><tr><th>hello</th></tr><tr><td>world</td></tr></table></body></html>");
var table = doc.DocumentNode.SelectSingleNode("//table");
var tableRows = table.SelectNodes("tr");
var columns = tableRows[0].SelectNodes("th/text()");
for (int i = 1; i < tableRows.Count; i++)
{
for (int e = 0; e < columns.Count; e++)
{
var value = tableRows[i].SelectSingleNode($"td[{e + 1}]");
Console.Write(columns[e].InnerText + ":" + value.InnerText);
}
Console.WriteLine();
}
If you want to set to a new color or prevent the change of the color of a specific link after visiting it, add inside the tag of that link:
<a style="text-decoration:none; color:#ff0000;" href="link.html">test link</a>
Above the color is #ff0000 but you can make it anything you'd like.
use sc.nextLine(); two time so that we can read the last line of string
sc.nextLine() sc.nextLine()
What Asaph said is right. However, not every YouTube video contains all nine thumbnails. Also, the thumbnails' image sizes depends on the video (the numbers below are based on one). There are some thumbnails guaranteed to exist:
Width | Height | URL
------|--------|----
120 | 90 | https://i.ytimg.com/vi/<VIDEO ID>/1.jpg
120 | 90 | https://i.ytimg.com/vi/<VIDEO ID>/2.jpg
120 | 90 | https://i.ytimg.com/vi/<VIDEO ID>/3.jpg
120 | 90 | https://i.ytimg.com/vi/<VIDEO ID>/default.jpg
320 | 180 | https://i.ytimg.com/vi/<VIDEO ID>/mq1.jpg

320 | 180 | https://i.ytimg.com/vi/<VIDEO ID>/mq3.jpg
320 | 180 | https://i.ytimg.com/vi/<VIDEO ID>/mqdefault.jpg
480 | 360 | https://i.ytimg.com/vi/<VIDEO ID>/0.jpg
480 | 360 | https://i.ytimg.com/vi/<VIDEO ID>/hq1.jpg
480 | 360 | https://i.ytimg.com/vi/<VIDEO ID>/hq2.jpg
480 | 360 | https://i.ytimg.com/vi/<VIDEO ID>/hq3.jpg
480 | 360 | https://i.ytimg.com/vi/<VIDEO ID>/hqdefault.jpg
Additionally, the some other thumbnails may or may not exist. Their presence is probably based on whether the video is high-quality.
Width | Height | URL
------|--------|----
640 | 480 | https://i.ytimg.com/vi/<VIDEO ID>/sd1.jpg

You can find JavaScript and PHP scripts to retrieve thumbnails and other YouTube information in:
You can also use the YouTube Video Information Generator tool to get all the information about a YouTube video by submitting a URL or video id.
Here is an example of code, that attempts to featch AJAX data from /Ajax/_AjaxGetItemListHelp/
URL. Upon success, it removes all items from dropdown list with id
= OfferTransModel_ItemID
and then it fills it with new items based on AJAX call's result:
if (productgrpid != 0) {
$.ajax({
type: "POST",
url: "/Ajax/_AjaxGetItemListHelp/",
data:{text:"sam",OfferTransModel_ItemGrpid:productgrpid},
contentType: "application/json",
dataType: "json",
success: function (data) {
$("#OfferTransModel_ItemID").empty();
$.each(data, function () {
$("#OfferTransModel_ItemID").append($("<option>
</option>").val(this['ITEMID']).html(this['ITEMDESC']));
});
}
});
}
Returned AJAX result is expected to return data encoded as AJAX array, where each item contains ITEMID
and ITEMDESC
elements. For example:
{
{
"ITEMID":"13",
"ITEMDESC":"About"
},
{
"ITEMID":"21",
"ITEMDESC":"Contact"
}
}
The OfferTransModel_ItemID
listbox is populated with above data and its code should look like:
<select id="OfferTransModel_ItemID" name="OfferTransModel[ItemID]">
<option value="13">About</option>
<option value="21">Contact</option>
</select>
When user selects About
, form submits 13
as value for this field and 21
when user selects Contact
and so on.
Fell free to modify above code if your server returns URL in a different format.
It makes sure that the returned object (which is an RValue at that point) can't be modified. This makes sure the user can't do thinks like this:
myFunc() = Object(...);
That would work nicely if myFunc
returned by reference, but is almost certainly a bug when returned by value (and probably won't be caught by the compiler). Of course in C++11 with its rvalues this convention doesn't make as much sense as it did earlier, since a const object can't be moved from, so this can have pretty heavy effects on performance.
In ONLINE mode the new index is built while the old index is accessible to reads and writes. any update on the old index will also get applied to the new index. An antimatter column is used to track possible conflicts between the updates and the rebuild (ie. delete of a row which was not yet copied). See Online Index Operations. When the process is completed the table is locked for a brief period and the new index replaces the old index. If the index contains LOB columns, ONLINE operations are not supported in SQL Server 2005/2008/R2.
In OFFLINE mode the table is locked upfront for any read or write, and then the new index gets built from the old index, while holding a lock on the table. No read or write operation is permitted on the table while the index is being rebuilt. Only when the operation is done is the lock on the table released and reads and writes are allowed again.
Note that in SQL Server 2012 the restriction on LOBs was lifted, see Online Index Operations for indexes containing LOB columns.
When creating the colors, you may use rgb
and set its alpha
argument:
plot(1:10, col = rgb(red = 1, green = 0, blue = 0, alpha = 0.5),
pch = 16, cex = 4)
points((1:10) + 0.4, col = rgb(red = 0, green = 0, blue = 1, alpha = 0.5),
pch = 16, cex = 4)
Please see ?rgb
for details.
I had this requirement recently and used other posts from this question to create this script:
$("select[multiple]").each(function() {
$(this).css("height","100%")
.attr("size",this.length);
})
Add the reference again from ./packages/Microsoft.AspNet.Mvc.[version]/lib/net45/System.Web.Mvc.dll
You can do it by using a formula and including the viewport width.
font-size: calc(7px + .5vw);
This sets the minimum font size at 7px and amplifies it by .5vw depending on the viewport width.
Good luck!
Often it is easier to parse without VBA, when you don't want to enable macros. This can be done with the replace function. Enter your start and end nodes into cells B1 and C1.
Cell A1: {your XML here}
Cell B1: <X>
Cell C1: </X>
Cell D1: =REPLACE(A1,1,FIND(A2,A1)+LEN(A2)-1,"")
Cell E1: =REPLACE(A4,FIND(A3,A4),LEN(A4)-FIND(A3,A4)+1,"")
And the result line E1 will have your parsed value:
Cell A1: {your XML here}
Cell B1: <X>
Cell C1: </X>
Cell D1: 24.365<X><Y>78.68</Y></PointN>
Cell E1: 24.365
There is also a descent solution which seems not to have any memory or performance overhead and be quite elegant:
string[] filters = new[]{"*.jpg", "*.png", "*.gif"};
string[] filePaths = filters.SelectMany(f => Directory.GetFiles(basePath, f)).ToArray();
size()
is a method specified in java.util.Collection
, which is then inherited by every data structure in the standard library. length
is a field on any array (arrays are objects, you just don't see the class normally), and length()
is a method on java.lang.String
, which is just a thin wrapper on a char[]
anyway.
Perhaps by design, Strings are immutable, and all of the top-level Collection subclasses are mutable. So where you see "length" you know that's constant, and where you see "size" it isn't.
No, there is not; see §3.2.4 "Compound Commands" in the Bash Reference Manual for information about the control structures that do exist. In particular, note the mention of break
and continue
, which aren't as flexible as goto
, but are more flexible in Bash than in some languages, and may help you achieve what you want. (Whatever it is that you want . . .)
It works if id value and name value are different:
<input type="password" class="form-control"name="password" id="mainpassword">
password: { required: true, } ,
cpassword: {required: true, equalTo: '#mainpassword' },
Neither JPA nor Hibernate annotations support the notion of a default column value. As a workaround to this limitation, set all default values just before you invoke a Hibernate save()
or update()
on the session. This closely as possible (short of Hibernate setting the default values) mimics the behaviour of the database which sets default values when it saves a row in a table.
Unlike setting the default values in the model class as this alternative answer suggests, this approach also ensures that criteria queries that use an Example
object as a prototype for the search will continue to work as before. When you set the default value of a nullable attribute (one that has a non-primitive type) in a model class, a Hibernate query-by-example will no longer ignore the associated column where previously it would ignore it because it was null.
You need to use event.stopPropagation()
$('#childDiv').click(function(event){
event.stopPropagation();
alert(event.target.id);
});?
Description: Prevents the event from bubbling up the DOM tree, preventing any parent handlers from being notified of the event.
You can override symbols in the stock libraries by creating a library with the same symbols and specifying the library in LD_PRELOAD
.
Some people use it to specify libraries in nonstandard locations, but LD_LIBRARY_PATH
is better for that purpose.
comm.Parameters.Add("person", "Myname");

hashFunction - the hash function to use to hash the data
Returns:
the HashCode of all of the bytes in the file
Throws:
IOException - if an I/O error occurs

let rangeOfFullString = NSRange(location: 0, length: fullString.count)//fullString.range(of: fullString)
let attributedString = NSMutableAttributedString(string:fullString)
attributedString.addAttribute(NSAttributedStringKey.foregroundColor, value: fullStringColor, range: rangeOfFullString)
attributedString.addAttribute(NSAttributedStringKey.foregroundColor, value: subStringColor, range: rangeOfSubString)
self.init(attributedString: attributedString)
}
}
You have mixed 2 standard.

I answer my own question reporting what therefore seems to be the most comprehensive overall procedure to Access IP Camera in Python OpenCV.
Given an IP camera:
IP
address port
where the IP address is accessed protocol
(HTTP/RTSP etc.) specified by the camera provider Then, if your camera is protected go ahead and find out:
username
password
Then use your data to run the following script:
"""Access IP Camera in Python OpenCV"""
import cv2
stream = cv2.VideoCapture('protocol://IP:port/1')
# Use the next line if your camera has a username and password
# stream = cv2.VideoCapture('protocol://username:password@IP:port/1')
while True:
r, f = stream.read()
cv2.imshow('IP Camera stream',f)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
cv2.destroyAllWindows()
NOTE: In my original question I specify to being working with Teledyne Dalsa Genie Nano XL Camera. Unfortunately for this kind of cameras this normal way of accessing the IP Camera video stream does not work and the Sapera SDK must be employed in order to grab frames from the device.
// 1. Random shuffle items
items.sort(function() {return 0.5 - Math.random()})
// 2. Get first item
var item = items[0]
Shorter:
var item = items.sort(function() {return 0.5 - Math.random()})[0];
For the impatient:

throw std::runtime_error(
(std::ostringstream()
<< "Could not load config file '"
<< configfile
<< "'"
).str()
);
It creates a temporary ostringstream, calls the << operators as necessary and then you wrap that in round brackets and call the .str() function on the evaluated result (which is an ostringstream) to pass a temporary std::string to the constructor of runtime_error.
Note: the ostringstream and the string are r-value temporaries and so go out of scope after this line ends. Your exception object's constructor MUST take the input string using either copy or (better) move semantics.
Additional: I don't necessarily consider this approach "best practice", but it does work and can be used at a pinch. One of the biggest issues is that this method requires heap allocations and so the operator << can throw. You probably don't want that happening; however, if your get into that state your probably have way more issues to worry about!
Since this question was asked/last answered, support for non string key types for maps for json Marshal/UnMarshal has been added through the use of TextMarshaler and TextUnmarshaler interfaces here. You could just implement these interfaces for your key types and then json.Marshal
would work as expected.
package main
import (
"encoding/json"
"fmt"
"strconv"
)
// Num wraps the int value so that we can implement the TextMarshaler and TextUnmarshaler
type Num int
func (n *Num) UnmarshalText(text []byte) error {
i, err := strconv.Atoi(string(text))
if err != nil {
return err
}
*n = Num(i)
return nil
}
func (n Num) MarshalText() (text []byte, err error) {
return []byte(strconv.Itoa(int(n))), nil
}
type Foo struct {
Number Num `json:"number"`
Title string `json:"title"`
}
func main() {
datas := make(map[Num]Foo)
for i := 0; i < 10; i++ {
datas[Num(i)] = Foo{Number: 1, Title: "test"}
}
jsonString, err := json.Marshal(datas)
if err != nil {
panic(err)
}
fmt.Println(datas)
fmt.Println(jsonString)
m := make(map[Num]Foo)
err = json.Unmarshal(jsonString, &m)
if err != nil {
panic(err)
}
fmt.Println(m)
}

Give boon a try:
https://github.com/RichardHightower/boon
It is wicked fast:
https://github.com/RichardHightower/json-parsers-benchmark
Don't take my word for it... check out the gatling benchmark.
https://github.com/gatling/json-parsers-benchmark
(Up to 4x is some cases, and out of the 100s of test. It also has a index overlay mode that is even faster. It is young but already has some users.)
It can parse JSON to Maps and Lists faster than any other lib can parse to a JSON DOM and that is without Index Overlay mode. With Boon Index Overlay mode, it is even faster.
It also has a very fast JSON lax mode and a PLIST parser mode. :) (and has a super low memory, direct from bytes mode with UTF-8 encoding on the fly).
It also has the fastest JSON to JavaBean mode too.
It is new, but if speed and simple API is what you are looking for, I don't think there is a faster or more minimalist API.

Removing from an array itself is not simple, as you then have to deal with resizing. This is one of the great advantages of using something like a List<int>
instead. It provides Remove
/RemoveAt
in 2.0, and lots of LINQ extensions for 3.0.
If you can, refactor to use a List<>
or similar.
The getRequestURL()
omits the port when it is 80 while the scheme is http
, or when it is 443 while the scheme is https
.
So, just use getRequestURL()
if all you want is obtaining the entire URL. This does however not include the GET query string. You may want to construct it as follows then:
StringBuffer requestURL = request.getRequestURL();
if (request.getQueryString() != null) {
requestURL.append("?").append(request.getQueryString());
}
String completeURL = requestURL.toString();
On client:
axios.get('/api', {
params: {
foo: 'bar'
}
});
On server:
function get(req, res, next) {
let param = req.query.foo
.....
}
Look at this method to see which fields are supported. You will find for LocalDateTime
:
•NANO_OF_SECOND
•NANO_OF_DAY
•MICRO_OF_SECOND
•MICRO_OF_DAY
•MILLI_OF_SECOND
•MILLI_OF_DAY
•SECOND_OF_MINUTE
•SECOND_OF_DAY
•MINUTE_OF_HOUR
•MINUTE_OF_DAY
•HOUR_OF_AMPM
•CLOCK_HOUR_OF_AMPM
•HOUR_OF_DAY
•CLOCK_HOUR_OF_DAY
•AMPM_OF_DAY
•DAY_OF_WEEK
•ALIGNED_DAY_OF_WEEK_IN_MONTH
•ALIGNED_DAY_OF_WEEK_IN_YEAR
•DAY_OF_MONTH
•DAY_OF_YEAR
•EPOCH_DAY
•ALIGNED_WEEK_OF_MONTH
•ALIGNED_WEEK_OF_YEAR
•MONTH_OF_YEAR
•PROLEPTIC_MONTH
•YEAR_OF_ERA
•YEAR
•ERA
The field INSTANT_SECONDS is - of course - not supported because a LocalDateTime
cannot refer to any absolute (global) timestamp. But what is helpful is the field EPOCH_DAY which counts the elapsed days since 1970-01-01. Similar thoughts are valid for the type LocalDate
(with even less supported fields).
If you intend to get the non-existing millis-since-unix-epoch field you also need the timezone for converting from a local to a global type. This conversion can be done much simpler, see other SO-posts.
Coming back to your question and the numbers in your code:
The result 1605 is correct
=> (2014 - 1970) * 365 + 11 (leap days) + 31 (in january 2014) + 3 (in february 2014)
The result 71461 is also correct => 19 * 3600 + 51 * 60 + 1
16105L * 86400 + 71461 = 1391543461 seconds since 1970-01-01T00:00:00 (attention, no timezone) Then you can subtract the timezone offset (watch out for possible multiplication by 1000 if in milliseconds).
UPDATE after given timezone info:
local time = 1391543461 secs
offset = 3600 secs (Europe/Oslo, winter time in february)
utc = 1391543461 - 3600 = 1391539861
As JSR-310-code with two equivalent approaches:
long secondsSinceUnixEpoch1 =
LocalDateTime.of(2014, 2, 4, 19, 51, 1).atZone(ZoneId.of("Europe/Oslo")).toEpochSecond();
long secondsSinceUnixEpoch2 =
LocalDate
.of(2014, 2, 4)
.atTime(19, 51, 1)
.atZone(ZoneId.of("Europe/Oslo"))
.toEpochSecond();
You can load HTML page partial, in your case is everything inside div#mytable.
setTimeout(function(){
$( "#mytable" ).load( "your-current-page.html #mytable" );
}, 2000); //refresh every 2 seconds
more information read this http://api.jquery.com/load/
<button id="refresh-btn">Refresh Table</button>
<script>
$(document).ready(function() {
function RefreshTable() {
$( "#mytable" ).load( "your-current-page.html #mytable" );
}
$("#refresh-btn").on("click", RefreshTable);
// OR CAN THIS WAY
//
// $("#refresh-btn").on("click", function() {
// $( "#mytable" ).load( "your-current-page.html #mytable" );
// });
});
</script>
Based on your comment under @Raul's answer, I can think of two ways to include a callback:
getScript
call the file that loads the css.<style>
. Your callback would be the callback from $.get
or whatever you use to load the css file contents.You can use rownum :
SELECT * FROM table WHERE rownum > 10 and rownum <= 20
This is the kind of stuff sed
was made for (of course, you need sed on your system for that).
sed 's/ex3/ex5/g' input.txt > output.txt
You will either need a Unix system or a Windows Cygwin kind of platform for this.
There is also GnuWin32 for sed. (GnuWin32 installation and usage).
An integer starting with 0 will cause fatal error as of PHP 7, because it might interpret it as an octal character.
Invalid octal literals
Previously, octal literals that contained invalid numbers were silently truncated (0128 was taken as 012). Now, an invalid octal literal will cause a parse error.
So you might want to remove leading zeros from your integer, first:
$var = ltrim($var, 0);
There are several ways to accomplish that in Vim. I don't know which are most similar to Sublime Text's though.
The first one would be via multiline insert mode. Put your cursor to the
second "a" in the first line, press Ctrl-V
, select all lines, then press I
, and
put in a doublequote. Pressing <esc>
will repeat the operation on every line.
The second one is via macros. Put the cursor on the first character, and start
recording a macro with qa
.
Go the your right with llll
, enter insert mode with
a
, put down a doublequote, exit insert mode, and go back to the beginning of
your row with <home>
(or equivalent). Press j
to move down one row.
Stop recording with q
.
And then replay the macro with @a
. Several times.
Does any of the above approaches work for you?

Everything in python is considered as object so functions are also objects. So you can use this method as well.
def fun1():
fun1.var = 100
print(fun1.var)
def fun2():
print(fun1.var)
fun1()
fun2()
print(fun1.var)
LIMIT is usually applied as the last operation, so the result will first be sorted and then limited to 20. In fact, sorting will stop as soon as first 20 sorted results are found.
the default access specifier is package.Classes can access the members of other classes in the same package.but outside the package it appears as private

In my case, I needed to check for the existence of a method with a specific name, so I used an interface for that
var plugin = this.pluginFinder.GetPluginIfInstalled<IPlugin>(pluginName) as dynamic;
if (plugin != null && plugin is ICustomPluginAction)
{
plugin.CustomPluginAction(action);
}
Also, interfaces can contain more than just methods:
Interfaces can contain methods, properties, events, indexers, or any combination of those four member types.

FOR /F "tokens=* USEBACKQ" %%F IN (`command`) DO (
SET var=%%F
)
ECHO %var%
I always use the USEBACKQ so that if you have a string to insert or a long file name, you can use your double quotes without screwing up the command.
Now if your output will contain multiple lines, you can do this
SETLOCAL ENABLEDELAYEDEXPANSION
SET count=1
FOR /F "tokens=* USEBACKQ" %%F IN (`command`) DO (
SET var!count!=%%F
SET /a count=!count!+1
)

Using testflight :
1) create the ipa file by development certificate
2) upload the ipa file on testflight
3) Now, to identify the device to be tested on , add the device id on apple account and refresh your development certificate. Download the updated certificate and upload it on testflight website. Check the device id you are getting.
4) Now email the ipa file to the testers.
5) While downloading the ipa file, if the testers are not getting any warnings, this means the device token + provisioning profile has been verified. So, the testers can now download the ipa file on device and do the testing job...
Probably, you have some problems with your server's configuration. Follow these steps to remove and create a new one, it might help you.
In Eclipse
1. Window -> Show view -> Servers (If you cannot see it, you might need to choose Others -> Server)
2. From Server view -> Delete the server which has problems.
3. Right click -> New -> Server : to create a new one
In my case, after new server was created, I get rid of this "localhost-config is missing"

Although this question has already been answered, I think this approach is better : http://jsfiddle.net/kjy112/3CvaD/ extract from this question on StackOverFlow google maps - open marker infowindow given the coordinates:
Each marker gets an "infowindow" entry :
function createMarker(lat, lon, html) {
var newmarker = new google.maps.Marker({
position: new google.maps.LatLng(lat, lon),
map: map,
title: html
});
newmarker['infowindow'] = new google.maps.InfoWindow({
content: html
});
google.maps.event.addListener(newmarker, 'mouseover', function() {
this['infowindow'].open(map, this);
});
}
I had a similar problem when I needed to make multiple sql queries. The problem was that some queries did not return the result and I wanted to print that result. And there was a mistake. As already written, there are several solutions.
if cursor.description is None:
# No recordset for INSERT, UPDATE, CREATE, etc
pass
else:
# Recordset for SELECT
As well as:
exist = cursor.fetchone()
if exist is None:
... # does not exist
else:
... # exists
One of the solutions is:
The try
and except
block lets you handle the error
/exceptions
. The finally
block lets you execute code, regardless of the result of the try
and except
blocks.
So the presented problem can be solved by using it.
s = """ set current query acceleration = enable;
set current GET_ACCEL_ARCHIVE = yes;
SELECT * FROM TABLE_NAME;"""
query_sqls = [i.strip() + ";" for i in filter(None, s.split(';'))]
for sql in query_sqls:
print(f"Executing SQL statements ====> {sql} <=====")
cursor.execute(sql)
print(f"SQL ====> {sql} <===== was executed successfully")
try:
print("\n****************** RESULT ***********************")
for result in cursor.fetchall():
print(result)
print("****************** END RESULT ***********************\n")
except Exception as e:
print(f"SQL: ====> {sql} <==== doesn't have output!\n")
# print(str(e))
output:
Executing SQL statements ====> set current query acceleration = enable; <=====
SQL: ====> set current query acceleration = enable; <==== doesn't have output!
Executing SQL statements ====> set current GET_ACCEL_ARCHIVE = yes; <=====
SQL: ====> set current GET_ACCEL_ARCHIVE = yes; <==== doesn't have output!
Executing SQL statements ====> SELECT * FROM TABLE_NAME; <=====
****************** RESULT ***********************
---------- DATA ----------
****************** END RESULT ***********************
The example above only presents a simple use as an idea that could help with your solution. Of course, you should also pay attention to other errors, such as the correctness of the query, etc.
Using Log4Net 1.2.13 we use the following configuration settings to allow date time in the file name.
<file type="log4net.Util.PatternString" value="E:/logname-%utcdate{yyyy-MM-dd}.txt" />
Which will provide files in the following convention: logname-2015-04-17.txt
With this it's usually best to have the following to ensure you're holding 1 log per day.
<rollingStyle value="Date" />
<datePattern value="yyyyMMdd" />
If size of file is a concern the following allows 500 files of 5MB in size until a new day spawns. CountDirection allows Ascending or Descending numbering of files which are no longer current.
<maxSizeRollBackups value="500" />
<maximumFileSize value="5MB" />
<rollingStyle value="Composite" />
<datePattern value="yyyyMMdd" />
<CountDirection value="1"/>
<staticLogFileName value="true" />
Lots of answers here, but some don't take into account
-l
)*.log
instead of log*
logs
that matches log*
)Here's a solution that handles all of them:
ls 2>/dev/null -Ubad1 -- log* | wc -l
Explanation:
-U
causes ls
to not sort the entries, meaning it doesn't need to load the entire directory listing in memory-b
prints C-style escapes for nongraphic characters, crucially causing newlines to be printed as \n
.-a
prints out all files, even hidden files (not strictly needed when the glob log*
implies no hidden files)-d
prints out directories without attempting to list the contents of the directory, which is what ls
normally would do-1
makes sure that it's on one column (ls does this automatically when writing to a pipe, so it's not strictly necessary)2>/dev/null
redirects stderr so that if there are 0 log files, ignore the error message. (Note that shopt -s nullglob
would cause ls
to list the entire working directory instead.)wc -l
consumes the directory listing as it's being generated, so the output of ls
is never in memory at any point in time.--
File names are separated from the command using --
so as not to be understood as arguments to ls
(in case log*
is removed)The shell will expand log*
to the full list of files, which may exhaust memory if it's a lot of files, so then running it through grep is be better:
ls -Uba1 | grep ^log | wc -l
This last one handles extremely large directories of files without using a lot of memory (albeit it does use a subshell). The -d
is no longer necessary, because it's only listing the contents of the current directory.
You can set the state of the checkbox based on the value:
$('#your-checkbox').prop('checked', value == 1);
I'm running 2.2 and there is no change, reports from others on 2.3 say the same. Android (bug) does not handle a .vcf nor a link to such a file on a web page via port 80, neither via http headers or direct streaming. It just is NOT SUPPORTED AT ALL.
Most updated way to achieve this is:
Add this to your EditText in XML:
android:imeOptions="actionSearch"
Then in your Activity/Fragment:
EditText.setOnEditorActionListener { _, actionId, _ ->
if (actionId == EditorInfo.IME_ACTION_SEARCH) {
// Do what you want here
return@setOnEditorActionListener true
}
return@setOnEditorActionListener false
}
Tabbing through controls usually happens sequentially as they appear on the HTML code.
Using tabindex, the tabbing will flow from control with the lowest tabindex to the control with the highest tabindex in tabindex sequential order
There's no direct equivalent of "friend" - the closest that's available (and it isn't very close) is InternalsVisibleTo. I've only ever used this attribute for testing - where it's very handy!
Example: To be placed in AssemblyInfo.cs
[assembly: InternalsVisibleTo("OtherAssembly")]
Unfortunately, there is no :click pseudo selector. If you want to change styling on click, you should use Jquery/Javascript. It certainly is better than the "hack" for pure HTML / CSS. But if you insist...

Your query should work for synonyms as well as the tables. However, you seem to expect indexes on views where there are not. Maybe is it materialized views ?
I benchmarked the answers of Anthony Damico, Brian Diggs and data_steve on a small sample tbl_df
and got the following results.
> data <- data.frame('a' = 1:3,
+ 'b' = c('a','b','c'),
+ 'c' = c('d', 'e', 'f'),
+ 'd' = c('g', 'h', 'i'))
> data <- tbl_df(data)
> cols <- c("b", "c", "d")
> microbenchmark(

However, when I evaluated on my own tbl_df
with ~1 million rows and 10 columns the results were quite different.

Do you have anything in machine.config that might be taking effect? Setting the session timeout in web.config should override any settings in IIS or machine.config, however, if you have a web.config file somewhere in a subfolder in your application, that setting will override the one in the root of your application.
Also, if I remember correctly, the timeout in IIS only affects .asp pages, not .aspx. Are you sure your session code in web.config is correct? It should look something like:
<sessionState
mode="InProc"
stateConnectionString="tcpip=127.0.0.1:42424"
stateNetworkTimeout="60"
sqlConnectionString="data source=127.0.0.1;Integrated Security=SSPI"
cookieless="false"
timeout="60"
/>
A better method is using strrpos + substr (faster than explode for that) :
$userfile_name = $_FILES['image']['name'];
$userfile_extn = substr($userfile_name, strrpos($userfile_name, '.')+1);
But, to check the type of a file, using mime_content_type is a better way : http://www.php.net/manual/en/function.mime-content-type.php
Another answer I did not see until now:

As of Java 8, some local variable name information is available through reflection. See the "Update" section below.
Complete information is often stored in class files. One compile-time optimization is to remove it, saving space (and providing some obsfuscation). However, when it is is present, each method has a local variable table attribute that lists the type and name of local variables, and the range of instructions where they are in scope.
Perhaps a byte-code engineering library like ASM would allow you to inspect this information at runtime. The only reasonable place I can think of for needing this information is in a development tool, and so byte-code engineering is likely to be useful for other purposes too.
Update: Limited support for this was added to Java 8. Parameter (a special class of local variable) names are now available via reflection. Among other purposes, this can help to replace @ParameterName
annotations used by dependency injection containers.
var el = document.querySelector("yourElement");
window.scroll({top: el.offsetTop, behavior: 'smooth'});
There should also be a YEAR().
As for comparing, you could compare dates that are the first days of those years and months, or you could convert the year/month pair into a number suitable for comparison (i.e. bigger = later). (Exercise left to the reader. For hints, read about the ISO date format.)
Or you could use multiple comparisons (i.e. years first, then months).
A safer way to approach breaking a foreach
or while
loop in PHP is to nest an incrementing counter variable and if
conditional inside of the original loop. This gives you tighter control than break;
which can cause havoc elsewhere on a complicated page.
Example:
// Setup a counter
$ImageCounter = 0;
// Increment through repeater fields
while ( condition ):
$ImageCounter++;
// Only print the first while instance
if ($ImageCounter == 1) {
echo 'It worked just once';
}
// Close while statement
endwhile;
Simple way to do it:
File fff = new File("/path/to/file");
FileInputStream fileInputStream = new FileInputStream(fff);
// int byteLength = fff.length();
// In android the result of file.length() is long
long byteLength = fff.length(); // byte count of the file-content
byte[] filecontent = new byte[(int) byteLength];
fileInputStream.read(filecontent, 0, (int) byteLength);
On OSX, I had to click the triple vertical dots, and uncheck a box in the settings section. Which can also be opened with f1
Another way to get the EF version you are using is to open the Package Manager Console (PMC) in Visual Studio and type Get-Package at the prompt. The first line with be for EntityFramework and list the version the project has installed.

It displays much more and you may have to scroll back up to find the EF line, but this is the easiest way I know of to find out.
Ok, I want to provide a small answer to one of the sub-questions that the OP asked that don't seem to be addressed in the existing questions. Caveat, I have not done any testing or code generation, or disassembly, just wanted to share a thought for others to possibly expound upon.
static
change the performance?The line in question:
uint64_t size = atol(argv[1])<<20;
I would look at the assembly generated for accessing size
and see if there are extra steps of pointer indirection involved for the non-static version.
Since there is only one copy of the variable whether it was declared static
or not, and the size doesn't change, I theorize that the difference is the location of the memory used to back the variable along with where it is used in the code further down.
Ok, to start with the obvious, remember that all local variables (along with parameters) of a function are provided space on the stack for use as storage. Now, obviously, the stack frame for main() never cleans up and is only generated once. Ok, what about making it static
? Well, in that case the compiler knows to reserve space in the global data space of the process so the location can not be cleared by the removal of a stack frame. But still, we only have one location so what is the difference? I suspect it has to do with how memory locations on the stack are referenced.
When the compiler is generating the symbol table, it just makes an entry for a label along with relevant attributes, like size, etc. It knows that it must reserve the appropriate space in memory but doesn't actually pick that location until somewhat later in process after doing liveness analysis and possibly register allocation. How then does the linker know what address to provide to the machine code for the final assembly code? It either knows the final location or knows how to arrive at the location. With a stack, it is pretty simple to refer to a location based one two elements, the pointer to the stackframe and then an offset into the frame. This is basically because the linker can't know the location of the stackframe before runtime.
try this:
$names = array('Jesse', 'joey', 'jelnny', 'justine');
$names = new ArrayObject($names);
echo '<pre>';
print_r($names);
vs this:
$names = array('Jesse', 'joey', 'jelnny', 'justine');
$names = new ArrayObject($names);
//echo '<pre>';
print_r($names);
and it shows what the PRE does very neatly

With Angular 5 and up, you DON'T have to use HttpParams. You can directly send your json object as shown below.
let data = {limit: "2"};
this.httpClient.get<any>(apiUrl, {params: data});
Please note that data values should be string, ie; { params: {limit: "2"}}
Use HttpParams, HttpClient from @angular/common/http
import { HttpParams, HttpClient } from '@angular/common/http';
...
constructor(private httpClient: HttpClient) { ... }
...
let params = new HttpParams();
params = params.append("page", 1);
....
this.httpClient.get<any>(apiUrl, {params: params});
Also, try stringifying your nested object using JSON.stringify()
.
Whoa there!
There's a potentially serious problem with this code, because it ignores the character encoding specified in the String
(which is UTF-8 by default). When you call String.getBytes()
the platform default encoding is used to encode Unicode characters to bytes. So, the parser may think it's getting UTF-8 data when in fact it's getting EBCDIC or something… not pretty!
Instead, use the parse method that takes an InputSource, which can be constructed with a Reader, like this:
import java.io.StringReader;
import org.xml.sax.InputSource;
…
return builder.parse(new InputSource(new StringReader(xml)));
It may not seem like a big deal, but ignorance of character encoding issues leads to insidious code rot akin to y2k.
Most of the time this compile error comes when unicode(UTF-8 encoded) file compiling
javac -encoding UTF-8 HelloWorld.java
and also You can add this compile option to your IDE
ex: Intellij idea
(File>settings>Java Compiler) add as additional command line parameter
-encoding : encoding Set the source file encoding name, such as EUC-JP and UTF-8.. If -encoding is not specified, the platform default converter is used. (DOC)
I was able to achieve this with the following :
Swift 3
override func didMoveToParentViewController(parent: UIViewController?) {
super.didMoveToParentViewController(parent)
if parent == nil {
println("Back Button pressed.")
delegate?.goingBack()
}
}
Swift 4
override func didMove(toParent parent: UIViewController?) {
super.didMove(toParent: parent)
if parent == nil {
debugPrint("Back Button pressed.")
}
}
No need of custom back button.
try with this after add ANDROID_HOME on your Environment Variable, work well on my mac
flutter config --android-sdk ANDROID_HOME
First one is a syntax error. Maybe you meant the difference between
const char * mychar
and
char * const mychar
In that case, the first one is a pointer to data that can't change, and the second one is a pointer that will always point to the same address.
A slightly shorter version using reduce
:
things.stream()
.map(this::resolve)
.reduce(Optional.empty(), (a, b) -> a.isPresent() ? a : b );
You could also move the reduce function to a static utility method and then it becomes:
.reduce(Optional.empty(), Util::firstPresent );
Define a ViewPager in your layout .xml:
<android.support.v4.view.ViewPager
android:id="@+id/example_pager"
android:layout_width="fill_parent"
android:layout_height="@dimen/abc_action_bar_default_height" />
And then, in your activity / fragment, set a custom pager adapter:
In an activity:
protected void onCreate(Bundle savedInstanceState) {
PagerAdapter adapter = new PagerAdapter(getSupportFragmentManager());
ViewPager pager = (ViewPager) findViewById(R.id.example_pager);
pager.setAdapter(adapter);
// pager.setOnPageChangeListener(this); // You can set a page listener here
pager.setCurrentItem(0);
}
In a fragment:
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_layout, container, false);
if (view != null) {
PagerAdapter adapter = new PagerAdapter(getSupportFragmentManager());
ViewPager pager = (ViewPager) view.findViewById(R.id.example_pager);
pager.setAdapter(adapter);
// pager.setOnPageChangeListener(this); // You can set a page listener here
pager.setCurrentItem(0);
}
return view;
}
Create our custom pager class:
// setup your PagerAdapter which extends FragmentPagerAdapter
class PagerAdapter extends FragmentPagerAdapter {
public static final int NUM_PAGES = 2;
private CustomFragment[] mFragments = new CustomFragment[NUM_PAGES];
public PagerAdapter(FragmentManager fragmentManager) {
super(fragmentManager);
}
@ Override
public int getCount() {
return NUM_PAGES;
}
@ Override
public Fragment getItem(int position) {
if (mFragments[position] == null) {
// this calls the newInstance from when you setup the ListFragment
mFragments[position] = new CustomFragment();
}
return mFragments[position];
}
}
This occurred for me due to changing the names of certain dataset fields within BIDS that were being referenced by parameters. I forgot to go into the parameters and reassign a default value (the default value of the parameter didn't automatically change to the newly renamed dataset field. Instead .
This is a good summary I found:
The Carriage Return (CR) character (0x0D
, \r
) moves the cursor to the beginning of the line without advancing to the next line. This character is used as a new line character in Commodore and Early Macintosh operating systems (OS-9 and earlier).
The Line Feed (LF) character (0x0A
, \n
) moves the cursor down to the next line without returning to the beginning of the line. This character is used as a new line character in UNIX based systems (Linux, Mac OSX, etc)
The End of Line (EOL) sequence (0x0D 0x0A
, \r\n
) is actually two ASCII characters, a combination of the CR and LF characters. It moves the cursor both down to the next line and to the beginning of that line. This character is used as a new line character in most other non-Unix operating systems including Microsoft Windows, Symbian OS and others.
Given that commonly 1 = true
and 0 = false
, all you need to do is count the number of rows, and cast to a boolean
.
Hence, your posted code only needs a COUNT()
function added:
SELECT CAST(COUNT(1) AS BIT) AS Expr1
FROM [User]
WHERE (UserID = 20070022)
if you want to encode or decode an array from or to JSON you can use these functions
$myJSONString = json_encode($myArray);
$myArray = json_decode($myString);
json_encode will result in a JSON string, built from an (multi-dimensional) array. json_decode will result in an Array, built from a well formed JSON string
with json_decode you can take the results from the API and only output what you want, for example:
echo $myArray['payload']['ign'];
As mentioned in the comments, conda support for jupyter notebooks is needed to switch kernels. Seems like this support is now available through conda itself (rather than relying on pip). http://docs.continuum.io/anaconda/user-guide/tasks/use-jupyter-notebook-extensions/
conda install nb_conda
which brings three other handy extensions in addition to Notebook Conda Kernels.
Starting with v0.16.0
, DF.assign()
could be used to assign new columns (single/multiple) to a DF
. These columns get inserted in alphabetical order at the end of the DF
.
This becomes advantageous compared to simple assignment in cases wherein you want to perform a series of chained operations directly on the returned dataframe.
Consider the same DF
sample demonstrated by @DSM:
df = pd.DataFrame({"A": [1,2,3], "B": [2,3,4]})
df
Out[18]:
A B
0 1 2
1 2 3
2 3 4
df.assign(C="",D=np.nan)
Out[21]:
A B C D
0 1 2 NaN
1 2 3 NaN
2 3 4 NaN
Note that this returns a copy with all the previous columns along with the newly created ones. In order for the original DF
to be modified accordingly, use it like : df = df.assign(...)
as it does not support inplace
operation currently.
descending alphabet:
List<String> list;
...
Collections.sort(list);
Collections.reverse(list);
return RedirectToAction("ActionName", "ControllerName");
That is the correct event. Maybe it's not wired up correctly?
<TabControl SelectionChanged="TabControl_SelectionChanged">
<TabItem Header="One"/>
<TabItem Header="2"/>
<TabItem Header="Three"/>
</TabControl>
in the codebehind....
private void TabControl_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
int i = 34;
}
if I set a breakpoint on the i = 34 line, it ONLY breaks when i change tabs, even when the tabs have child elements and one of them is selected.
Apple lifted the restrictions on non-Objective C/C/C++ apps -- you just can't load code that isn't in the app bundle.
MonoTouch lets you use .NET languages -- C# is directly supported, but if you have Windows, you can make assemblies in any .NET language and use it.
There are rumors that Apple is going to support other languages directly -- I keep hearing ruby, but they are just rumors.
I think Lua is being used for game logic on a lot of apps.
EDIT (in 2018): Generally you can use any language that you can get to compile for iOS or even install language interpreters. The main thing you cannot do is load code from the Internet that wasn't in the app bundle.
People do this all of the time anyway (see React Native apps loading JavaScript from servers), but, technically, it's not allowed. The main thing that will get you attention from Apple if you make some kind of App Store that loads whole App-like things.
EDIT (in 2020): from @Pylot in comments: I know this is a long time ago, but now at least technically you can load code that isn’t embedded in the app, as you can write with JavaScript using the webview. Not staying your answer is wrong or anything, I definitely agree with you. but I was looking for something and found this post on the way. Figured if anyone sees this it might help them out.
Use a generic Last<T>
. That will work with ANY IEnumerable
, including string.
public static IEnumerable<T> Last<T>(this IEnumerable<T> enumerable, int nLastElements)
{
int count = Math.Min(enumerable.Count(), nLastElements);
for (int i = enumerable.Count() - count; i < enumerable.Count(); i++)
{
yield return enumerable.ElementAt(i);
}
}
And a specific one for string:
public static string Right(this string str, int nLastElements)
{
return new string(str.Last(nLastElements).ToArray());
}
There is no semicolon at the end of that instruction causing the error.
EDIT
Like RiverC pointed out, there is no semicolon at the end of the previous line!
require ("scripts/connect.php")
EDIT
It seems you have no-semicolons whatsoever.
http://php.net/manual/en/language.basic-syntax.instruction-separation.php
As in C or Perl, PHP requires instructions to be terminated with a semicolon at the end of each statement.
I would just do:
private static Timer timer;
private static void Main()
{
timer = new Timer(_ => OnCallBack(), null, 1000 * 10,Timeout.Infinite); //in 10 seconds
Console.ReadLine();
}
private static void OnCallBack()
{
timer.Dispose();
Thread.Sleep(3000); //doing some long operation
timer = new Timer(_ => OnCallBack(), null, 1000 * 10,Timeout.Infinite); //in 10 seconds
}
And ignore the period parameter, since you're attempting to control the periodicy yourself.
Your original code is running as fast as possible, since you keep specifying 0
for the dueTime
parameter. From Timer.Change
:
If dueTime is zero (0), the callback method is invoked immediately.
A different approach, because in my case I needed to also check whether it contained certain words (like 'test' in this example), not characters alone:
input_string = 'abc test'
input_string_test = input_string
allowed_list = ['a', 'b', 'c', 'test', ' ']
for allowed_list_item in allowed_list:
input_string_test = input_string_test.replace(allowed_list_item, '')
if not input_string_test:
# test passed
So, the allowed strings (char or word) are cut from the input string. If the input string only contained strings that were allowed, it should leave an empty string and therefore should pass if not input_string
.
Use a service api.
URL: https://fcm.googleapis.com/fcm/send
Method Type: POST
Headers:
Content-Type: application/json
Authorization: key=your api key
Body/Payload:
{ "notification": {
"title": "Your Title",
"text": "Your Text",
"click_action": "OPEN_ACTIVITY_1" // should match to your intent filter
},
"data": {
"keyname": "any value " //you can get this data as extras in your activity and this data is optional
},
"to" : "to_id(firebase refreshedToken)"
}
And with this in your app you can add below code in your activity to be called:
<intent-filter>
<action android:name="OPEN_ACTIVITY_1" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>

First off, EC2 and Elastic Compute Cloud are the same thing.
Next, AWS encompasses the range of Web Services that includes EC2 and Elastic Beanstalk. It also includes many others such as S3, RDS, DynamoDB, and all the others.
EC2 is Amazon's service that allows you to create a server (AWS calls these instances) in the AWS cloud. You pay by the hour and only what you use. You can do whatever you want with this instance as well as launch n
number of instances.
Elastic Beanstalk is one layer of abstraction away from the EC2 layer. Elastic Beanstalk will setup an "environment" for you that can contain a number of EC2 instances, an optional database, as well as a few other AWS components such as a Elastic Load Balancer, Auto-Scaling Group, Security Group. Then Elastic Beanstalk will manage these items for you whenever you want to update your software running in AWS. Elastic Beanstalk doesn't add any cost on top of these resources that it creates for you. If you have 10 hours of EC2 usage, then all you pay is 10 compute hours.
For running Wordpress, it is whatever you are most comfortable with. You could run it straight on a single EC2 instance, you could use a solution from the AWS Marketplace, or you could use Elastic Beanstalk.
In the case that you want to reduce system operations and just focus on the website, then Elastic Beanstalk would be the best choice for that. Elastic Beanstalk supports a PHP stack (as well as others). You can keep your site in version control and easily deploy to your environment whenever you make changes. It will also setup an Autoscaling group which can spawn up more EC2 instances if traffic is growing.
Here's the first result off of Google when searching for "elastic beanstalk wordpress": https://www.otreva.com/blog/deploying-wordpress-amazon-web-services-aws-ec2-rds-via-elasticbeanstalk/

There is timeline.sty floating around.
The syntax is simpler than using tikz:
%%% In LaTeX:
%%% \begin{timeline}{length}(start,stop)

%%% .
%%% \end{timeline}
%%%
%%% in plain TeX
%%% \timeline{length}(start,stop)
%%% .
%%% .
%%% .
%%% \endtimeline
%%% in between the two, we may have:
%%% \item{date}{description}
%%% \item[sortkey]{date}{description}
%%% \optrule
%%%
%%% the options to timeline are:
%%% length The amount of vertical space that the timeline should
%%% use.
%%% (start,stop) indicate the range of the timeline. All dates or
%%% sortkeys should lie in the range [start,stop]
%%%
%%% \item without the sort key expects date to be a number (such as a
%%% year).
%%% \item with the sort key expects the sort key to be a number; date
%%% can be anything. This can be used for log scale time lines
%%% or dates that include months or days.
%%% putting \optrule inside of the timeline environment will cause a
%%% vertical rule to be drawn down the center of the timeline.
I've used python's datetime.data.toordinal to convert dates to 'sort keys' in the context of the package.
Error message looks like this
Error message => ORA-00001: unique constraint (schema.unique_constraint_name) violated
ORA-00001 occurs when: "a query tries to insert a "duplicate" row in a table". It makes an unique constraint to fail, consequently query fails and row is NOT added to the table."
Solution:
Find all columns used in unique_constraint, for instance column a, column b, column c, column d collectively creates unique_constraint and then find the record from source data which is duplicate, using following queries:
-- to find <<owner of the table>> and <<name of the table>> for unique_constraint
select *
from DBA_CONSTRAINTS
where CONSTRAINT_NAME = '<unique_constraint_name>';
Then use Justin Cave's query (pasted below) to find all columns used in unique_constraint:
SELECT column_name, position
FROM all_cons_columns
WHERE constraint_name = <<name of constraint from the error message>>
AND owner = <<owner of the table>>
AND table_name = <<name of the table>>
-- to find duplicates
select column a, column b, column c, column d
from table
group by column a, column b, column c, column d
having count (<any one column used in constraint > ) > 1;
you can either delete that duplicate record from your source data (which was a select query in my particular case, as I experienced it with "Insert into select") or modify to make it unique or change the constraint.
In Angular 7, the following simple example would work (assuming dictionary is in a variable called d
):
my.component.ts:
keys: string[] = []; // declaration of class member 'keys'
// component code ...
this.keys = Object.keys(d);
my.component.html: (will display list of key:value pairs)
<ul *ngFor="let key of keys">
{{key}}: {{d[key]}}
</ul>
profile name is not valid [SQLSTATE 42000] (Error 14607)
This happened to me after I copied job script from old SQL server to new SQL server. In SSMS, under Management, the Database Mail profile name was different in the new SQL Server. All I had to do was update the name in job script.

Drag a tooltip control from the toolbox onto your form. You don't really need to give it any properties other than a name. Then, in the properties of the control you wish to have a tooltip on, look for a new property with the name of the tooltip control you just added. It will by default give you a tooltip when the cursor hovers the control.
Heres a another take on this problem, using recursion and without using mutable variables. Also, im not using setInterval
so theres no cleanup that has to be done.
Having this HTML
<section id="testimonials">
<h2>My testimonial spinner</h2>
<div class="testimonial">
<p>First content</p>
</div>
<div class="testimonial">
<p>Second content</p>
</div>
<div class="testimonial">
<p>Third content</p>
</div>
</section>
Using ES2016
Here you call the function recursively and update the arguments.
const testimonials = $('#testimonials')
.children()
.filter('div.testimonial');
const showTestimonial = index => {
testimonials.hide();
$(testimonials[index]).fadeIn();
return index === testimonials.length
? showTestimonial(0)
: setTimeout(() => { showTestimonial(index + 1); }, 10000);
}
showTestimonial(0); // id of the first element you want to show.
This is still the highest SO-question on Google when searching for this error, so let's bump it.
When getting this error and not wanting to deep-dive into the NGINX settings immediately, you might want to check your outputs to the debug console. In my case I was outputting loads of text to the FirePHP / Chromelogger console, and since this is all sent as a header, it was causing the overflow.
It might not be needed to change the webserver settings if this error is caused by just sending insane amounts of log messages.
There is an easier way using Xcode (without using command line tools and looking up addresses one at a time)
Take any .xcarchive file. If you have one from before you can use that. If you don't have one, create one by running the Product > Archive from Xcode.
Right click on the .xcarchive file and select 'Show Package Contents'
Copy the dsym file (of the version of the app that crashed) to the dSYMs folder
Copy the .app file (of the version of the app that crashed) to the Products > Applications folder
Edit the Info.plist and edit the CFBundleShortVersionString and CFBundleVersion under the ApplicationProperties dictionary. This will help you identify the archive later
Double click the .xcarchive to import it to Xcode. It should open Organizer.
Go back to the crash log (in Devices window in Xcode)
Drag your .crash file there (if not already present)
The entire crash log should now be symbolicated. If not, then right click and select 'Re-symbolicate crash log'
In this answer I copy Dennis Williamson's answer and modify it slightly to allow a vast speed increase when piping a column of many timestamps to the script. For example, piping 1000 timestamps to the original script with xargs -n1 on my machine took 6.929s as opposed to 0.027s with this modified version:
#!/bin/bash
LANG=C
if [[ -z "$1" ]]
then
if [[ -p /dev/stdin ]] # input from a pipe
then
cat - | gawk '{ print strftime("%c", $1); }'
else
echo "No timestamp given." >&2
exit
fi
else
date -d @$1 +%c
fi
I got this to work using a .user.ini file in the same directory as my index.php script that loads my app. Here are the contents:
upload_max_filesize = "20M"
post_max_size = "25M"
This is the recommended solution for Heroku.
Note that HTTP doesn't typically keep TCP connections open for any longer than it takes to transmit the page to the client; and it usually takes much more time for the user to read a web page than it takes to download the page... while the user is viewing the page, he adds no load to the server at all.
So the number of people that can be simultaneously viewing your web site is much larger than the number of TCP connections that it can simultaneously serve.
Below image will let you understand the padding and margin-
You did not migrated all changes you made in model. so
1) python manage.py makemigrations
2) python manage.py migrate
3) python manag.py runserver
it works 100%
The bash way - convert the dates into %y%m%d format and then you can do this straight from the command line:
echo $(( ($(date --date="031122" +%s) - $(date --date="021020" +%s) )/(60*60*24) ))
You can simply add @HostBinding('class') class = 'someClass';
inside your @Component class.
Example:
@Component({
selector: 'body',
template: 'app-element'
})
export class App implements OnInit {
@HostBinding('class') class = 'someClass';
constructor() {}
ngOnInit() {}
}

Easiest Solution:> Enviroment Variables handy little critters.
If the other person is to install/uncompress whatever to wherever on their respective system drive (usualy c:).
For demonstration purposes call our app "test.exe" (could be any executable/file doesn't have to be exe) and it is to be installed/uncompressed to folder MYCOMPANY\MYAPP\
Then just make a shortcut that uses %SystemDrive%\MYCOMPANY\MYAPP\test.exe as target and %SystemDrive%\MYCOMPANY\MYAPP\ as start in.
So now you would like to deploy it. Using an app like "WinRAR".
Easy way is using self-extraction zip file, neatly packaged as an ".exe" I would use one for my shortcut and another for the app. There is ways to make one self-extraction zip file that extracts different files to different directories, but i haven't played with it yet.
Another way is to make a selfextract for the shorcut, embed it inside the selfextract for the app and then apply a run once script,being that you know where the file is going to be. etc.
If you want to enable the installer to use custom installation/uncompress directories, then rather have a look at NSIS a scriptable install system.
Play around it's fun, hope my info helped.
remember, SSL/TLS operates at the Transport Layer, so all the crypto goo happens under the application-layer HTTP stuff.

I just needed to remove this effect from my text input fields, and I couldn't get the other techniques to work quite right, but this is what works for me;

}
Tested in Firefox and in Chrome.
A small modification to Ken Williams' answer, adding optional params na.rm
and return_multiple
.
Unlike the answers relying on names()
, this answer maintains the data type of x
in the returned value(s).
stat_mode <- function(x, return_multiple = TRUE, na.rm = FALSE) {
if(na.rm){
x <- na.omit(x)
}
ux <- unique(x)
freq <- tabulate(match(x, ux))
mode_loc <- if(return_multiple) which(freq==max(freq)) else which.max(freq)
return(ux[mode_loc])
}
To show it works with the optional params and maintains data type:
foo <- c(2L, 2L, 3L, 4L, 4L, 5L, NA, NA)
bar <- c('mouse','mouse','dog','cat','cat','bird',NA,NA)
str(stat_mode(foo)) # int [1:3] 2 4 NA
str(stat_mode(bar)) # chr [1:3] "mouse" "cat" NA
str(stat_mode(bar, na.rm=T)) # chr [1:2] "mouse" "cat"
str(stat_mode(bar, return_mult=F, na.rm=T)) # chr "mouse"
Thanks to @Frank for simplification.
The short answer is "yes". A sample ldapsearch
command to query an Active Directory server is:
ldapsearch \
-x -h ldapserver.mydomain.com \
-D "[email protected]" \
-W \
-b "cn=users,dc=mydomain,dc=com" \
-s sub "(cn=*)" cn mail sn
This would connect to an AD server at hostname ldapserver.mydomain.com
as user [email protected]
, prompt for the password on the command line and show name and email details for users in the cn=users,dc=mydomain,dc=com
subtree.
See Managing LDAP from the Command Line on Linux for more samples. See LDAP Query Basics for Microsoft Exchange documentation for samples using LDAP queries with Active Directory.
There is an option “unlimited scrollback buffer” which you can find under Preferences > Profiles > Terminal

In my case in the POST
response I want to have the authorization header
because I was having the JWT Token
in it.
So what I read from this post is the header I we want should be added as an Expose Header
from the back-end.
So what I did was added the Authorization
header to my Exposed Header like this in my filter class
.
response.addHeader("Access-Control-Expose-Headers", "Authorization");
response.addHeader("Access-Control-Allow-Headers", "Authorization, X-PINGOTHER, Origin, X-Requested-With, Content-Type, Accept, X-Custom-header");
response.addHeader(HEADER_STRING, TOKEN_PREFIX + token); // HEADER_STRING == Authorization
And at my Angular Side
In the Component.
this.authenticationService.login(this.f.email.value, this.f.password.value)
.pipe(first())
.subscribe(
(data: HttpResponse<any>) => {
console.log(data.headers.get('authorization'));
},
error => {
this.loading = false;
});
At my Service Side.
return this.http.post<any>(Constants.BASE_URL + 'login', {username: username, password: password},
{observe: 'response' as 'body'})
.pipe(map(user => {
return user;
}));

Css class to have a nice Div with scroll

<c:if test="${companies.size() > 0}">
</c:if>
This syntax works only in EL 2.2 or newer (Servlet 3.0 / JSP 2.2 or newer). If you're facing a XML parsing error because you're using JSPX or Facelets instead of JSP, then use gt
instead of >
.
<c:if test="${companies.size() gt 0}">
</c:if>
If you're actually facing an EL parsing error, then you're probably using a too old EL version. You'll need JSTL fn:length()
function then. From the documentation:
length( java.lang.Object) - Returns the number of items in a collection, or the number of characters in a string.
Put this at the top of JSP page to allow the fn
namespace:
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
Or if you're using JSPX or Facelets:
<... xmlns:fn="http://java.sun.com/jsp/jstl/functions">
And use like this in your page:
<p>The length of the companies collection is: ${fn:length(companies)}</p>
So to test with length of a collection:
<c:if test="${fn:length(companies) gt 0}">
</c:if>
Alternatively, for this specific case you can also simply use the EL empty
operator:
<c:if test="${not empty companies}">
</c:if>
Just use matrix
:
matrix(vec,nrow = 7,ncol = 7)
One advantage of using matrix
rather than simply altering the dimension attribute as Gavin points out, is that you can specify whether the matrix is filled by row or column using the byrow
argument in matrix
.
simple way you can do this by adding this css So, you just added this to CSS:
.modal-body {
position: relative;
padding: 20px;
height: 200px;
overflow-y: scroll;
}
and it's working!
use .filter(':has(:checkbox:checked)'
ie:
$('#mytable tr').filter(':has(:checkbox:checked)').each(function() {
$('#out').append(this.id);
});
typedef
defines a new data type. So you can have:
typedef char* my_string;
typedef struct{
int member1;
int member2;
} my_struct;
So now you can declare variables with these new data types
my_string s;
my_struct x;
s = "welcome";
x.member1 = 10;
For enum
, things are a bit different - consider the following examples:
enum Ranks {FIRST, SECOND};
int main()
{
int data = 20;
if (data == FIRST)
{
//do something
}
}
using typedef enum
creates an alias for a type:
typedef enum Ranks {FIRST, SECOND} Order;
int main()
{
Order data = (Order)20; // Must cast to defined type to prevent error
if (data == FIRST)
{
//do something
}
}
In my case I had a directory with 800+ files ending with .StoredProcedure.sql
(they were scripted with SSMS).
The solutions posted above didn't work. But I came up with this:
(Based on answers to batch programming - get relative path of file)
@echo off
setlocal enabledelayedexpansion
for %%f in (*) do (
set B=%%f
set B=!B:%CD%\=!
ren "!B!" "!B:.StoredProcedure=!"
)
The above script removes the substring .StoredProcedure
from the filename. I'm sure it can be adapted to cover more cases, ask for input and be overall more generic.
Some Improvements in Sudheesh B Nair's answer, i have noticed it will wait for handler even while pressing back twice immediately, so cancel handler as shown below. I have cancled toast also to prevent it to display after app exit.
boolean doubleBackToExitPressedOnce = false;
Handler myHandler;
Runnable myRunnable;
Toast myToast;
@Override
public void onBackPressed() {
if (doubleBackToExitPressedOnce) {
myHandler.removeCallbacks(myRunnable);
myToast.cancel();
super.onBackPressed();
return;
}
this.doubleBackToExitPressedOnce = true;
myToast = Toast.makeText(this, "Please click BACK again to exit", Toast.LENGTH_SHORT);
myToast.show();
myHandler = new Handler();
myRunnable = new Runnable() {
@Override
public void run() {
doubleBackToExitPressedOnce = false;
}
};
myHandler.postDelayed(myRunnable, 2000);
}
use labelpad parameter:
pl.xlabel("...", labelpad=20)
or set it after:
ax.xaxis.labelpad = 20
Also you can setup extJs writer
with encode
: true
and it will send data regularly (and, hence, you will be able to retrieve data via $_POST
and $_GET
).
... the values will be sent as part of the request parameters as opposed to a raw post (via docs for encode config of Ext.data.writer.Json)
UPDATE
Also docs say that:
The encode option should only be set to true when a root is defined
So, probably, writer
's root
config is required.
There is also this:
select m from table where not regexp_like(m, '^[0-9]\d+$')
which selects the rows that contains characters from the column you want (which is m in the example but you can change).
Most of the combinations don't work properly in Oracle platforms but this does. Sharing for future reference.
There's a variable conflict in your run_cmd
function:
var me = this;
child.stdout.on('data', function(me, data) {
// me is overriden by function argument
cb(me, data);
});
Simply change it to this:
var me = this;
child.stdout.on('data', function(data) {
// One argument only!
cb(me, data);
});
In order to see errors always add this:
child.stderr.on('data', function(data) {
console.log( data );
});
EDIT You're code fails because you are trying to run dir
which is not provided as a separate standalone program. It is a command in cmd
process. If you want to play with filesystem use native require( 'fs' )
.
Alternatively ( which I do not recommend ) you can create a batch file which you can then run. Note that OS by default fires batch files via cmd
.
There is no such option available in jar command itself. Look into the documentation:
-C dir Temporarily changes directories (cd dir) during execution of the jar command while processing the following inputfiles argument. Its operation is intended to be similar to the -C option of the UNIX tar utility. For example: jar uf foo.jar -C classes bar.class changes to the classes directory and add the bar.class from that directory to foo.jar. The following command, jar uf foo.jar -C classes . -C bin xyz.class changes to the classes directory and adds to foo.jar all files within the classes directory (without creating a classes directory in the jar file), then changes back to the original directory before changing to the bin directory to add xyz.class to foo.jar. If classes holds files bar1 and bar2, then here's what the jar file contains using jar tf foo.jar: META-INF/
META-INF/MANIFEST.MF
bar1
bar2
xyz.class
It seems like you want the files ignored but they have already been commited. .gitignore has no effect on files that are already in the repo so they need to be removed with git rm --cached
. The --cached
will prevent it from having any effect on your working copy and it will just mark as removed the next time you commit. After the files are removed from the repo then the .gitignore will prevent them from being added again.
But you have another problem with your .gitignore, you are excessively using wildcards and its causing it to match less than you expect it to. Instead lets change the .gitignore and try this.
.bundle
.DS_Store
db/*.sqlite3
log/*.log

// If your expected result is "http://foo.bar/?x=1&y=2&x=42"
url.searchParams.append('x', 42);

After two dozens of comments to understand the situation, it was found that the libhdf5.so.7
was actually a symlink (with several levels of indirection) to a file that was not shared between the queued processes and the interactive processes. This means even though the symlink itself lies on a shared filesystem, the contents of the file do not and as a result the process was seeing different versions of the library.
For future reference: other than checking LD_LIBRARY_PATH
, it's always a good idea to check a library with nm -D
to see if the symbols actually exist. In this case it was found that they do exist in interactive mode but not when run in the queue. A quick md5sum
revealed that the files were actually different.
I had the same problem but none of the answers above worked. The solution for me was to restore the Manager web application that is bundled with Tomcat.
Thanks to Joachim answer, I use the code to clear all back stack entry finally.

for (int i = 0; i < backStackCount; i++) {
// Get the back stack fragment id.
int backStackId = getSupportFragmentManager().getBackStackEntryAt(i).getId();
getSupportFragmentManager().popBackStack(backStackId,
FragmentManager.POP_BACK_STACK_INCLUSIVE);
} /* end of for */

Scan your domain on this sslTesturl, and see if the connection is allowed for your device version.
If lower version devices(like < Android 4.4.2 etc) are not able to connect due to TLS support, then try adding this to your Nginx config file,
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
I was facing same issue. I tried everything possible for a day, but nothing worked. The dependency which was causing problem was using lower compile sdk, target sdk and min sdk. I created library module for the project, copied all the sources and matched the sdk versions with application sdk versions. And finally it worked like a charm.
json_decode will return the same array that was originally encoded. For instanse, if you
$array = json_decode($json, true);
echo $array['countryId'];
OR
$obj= json_decode($json);
echo $obj->countryId;
These both will echo 84. I think json_encode and json_decode function names are self-explanatory...
LINQ Generic Way:
public static Dictionary<int, string> ToList<T>() where T : struct =>
((IEnumerable<T>)Enum.GetValues(typeof(T))).ToDictionary(value => Convert.ToInt32(value), value => value.ToString());
Usage:
var enums = ToList<Enum>();
Here is what I would do:
find /path/to/dir -type f -iname "*filename*" -print0 | xargs -0 sed -i '/searchstring/s/old/new/g'
this will look for all files containing filename
in the file's name under the /path/to/dir
, than for every file found, search for the line with searchstring
and replace old
with new
.
Though if you want to omit looking for a specific file with a filename
string in the file's name, than simply do:
find /path/to/dir -type f -print0 | xargs -0 sed -i '/searchstring/s/old/new/g'
This will do the same thing above, but to all files found under /path/to/dir
.
I find that if you use a lot of spaces, the browser will wrap it properly. Don't worry about using an exact number of spaces, just throw a lot in there, and the browser should properly wrap to the first non space character on the next line.

In such case you will need to parse zip local header entries. Each file, stored in zip file, has preceding Local File Header entry, which (normally) contains enough information for decompression, Generally, you can make simple parsing of such entries in stream, select needed file, copy header + compressed file data to other file, and call unzip on that part (if you don't want to deal with the whole Zip decompression code or library).
In my case I had to add android:name=".activity.SkeletonAppActivity"
instead of android:name=".SkeletonAppActivity"
in the manifest file for the main activity.
SkeletonAppActivity
was in a different package from the application class. Good luck!
I ran into this problem today and none of the solutions posted here worked. However, the code posted here worked for a POST request:
// HTTP POST request
private void sendPost() throws Exception {
String url = "https://selfsolve.apple.com/wcResults.do";
URL obj = new URL(url);
HttpsURLConnection con = (HttpsURLConnection) obj.openConnection();
//add reuqest header
con.setRequestMethod("POST");
con.setRequestProperty("User-Agent", USER_AGENT);
con.setRequestProperty("Accept-Language", "en-US,en;q=0.5");
String urlParameters = "sn=C02G8416DRJM&cn=&locale=&caller=&num=12345";
// Send post request
con.setDoOutput(true);
DataOutputStream wr = new DataOutputStream(con.getOutputStream());
wr.writeBytes(urlParameters);
wr.flush();
wr.close();
int responseCode = con.getResponseCode();
System.out.println("\nSending 'POST' request to URL : " + url);
System.out.println("Post parameters : " + urlParameters);
System.out.println("Response Code : " + responseCode);
BufferedReader in = new BufferedReader(
new InputStreamReader(con.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
//print result
System.out.println(response.toString());
}
It turns out that it's not the authorization that's the problem. In my case, it was an encoding problem. The content-type I needed was application/json but from the Java documentation:
static String encode(String s, String enc)
Translates a string into application/x-www-form-urlencoded format using a specific encoding scheme.
The encode function translates the string into application/x-www-form-urlencoded.
Now if you don't set a Content-Type, you may get a 415 Unsupported Media Type error. If you set it to application/json or anything that's not application/x-www-form-urlencoded, you get an IOException. To solve this, simply avoid the encode method.
For this particular scenario, the following should work:
String data = "product[title]=" + title +
"&product[content]=" + content +
"&product[price]=" + price.toString() +
"&tags=" + tags;
Another small piece of information that might be helpful as to why the code breaks when creating the buffered reader is because the POST request actually only gets executed when conn.getInputStream() is called.
The year()
function just retrieves the year component of the underlying Date
object, so it returns a number.
Calling format('YYYY')
will invoke moment's string formatting functions, which will parse the format string supplied, and build a new string containing the appropriate data. Since you only are passing YYYY
, then the result will be a string containing the year.
If all you need is the year, then use the year()
function. It will be faster, as there is less work to do.
Do note that while years are the same in this regard, months are not! Calling format('M')
will return months in the range 1-12. Calling month()
will return months in the range 0-11. This is due to the same behavior of the underlying Date
object.
The following command prints the total number of commits on the current branch.
git shortlog -s -n | awk '{ sum += $1; } END { print sum; }' "$@"
It is made up of two parts:
Print the total logs number grouped by author (git shortlog -s -n
)
Example output
1445 John C
1398 Tom D
1376 Chrsitopher P
166 Justin T
166 You
Sum up the total commit number of each author, i.e. the first argument of each line, and print the result out (awk '{ sum += $1; } END { print sum; }' "$@"
)
Using the same example as above it will sum up 1445 + 1398 + 1376 + 166 + 166
. Therefore the output will be:
4,551
The strncpy()
function is the safer one: you have to pass the maximum length the destination buffer can accept. Otherwise it could happen that the source string is not correctly 0 terminated, in which case the strcpy()
function could write more characters to destination, corrupting anything which is in the memory after the destination buffer. This is the buffer-overrun problem used in many exploits
Also for POSIX API functions like read()
which does not put the terminating 0 in the buffer, but returns the number of bytes read, you will either manually put the 0, or copy it using strncpy()
.
In your example code, index
is actually not an index, but a count
- it tells how many characters at most to copy from source to destination. If there is no null byte among the first n bytes of source, the string placed in destination will not be null terminated
We can simply write the array data to the filesystem but this will raise one error in which ',' will be appended to the end of the file. To handle this below code can be used:
var fs = require('fs');
var file = fs.createWriteStream('hello.txt');
file.on('error', function(err) { Console.log(err) });
data.forEach(value => file.write(`${value}\r\n`));
file.end();
\r\n
is used for the new Line.
\n

None of these wonderful answers worked for me on a fresh install of Ubuntu. Instead, a clue from this answer did the trick for me.
I had to allow "simple" password store by setting this empty in ~/.subversion/config
:
password-stores =
There was no existing setting, so being empty is significant.
This was in addition to:
store-passwords = yes
in ~/.subversion/servers
.
In one-to-one relation one end must be principal and second end must be dependent. Principal end is the one which will be inserted first and which can exist without the dependent one. Dependent end is the one which must be inserted after the principal because it has foreign key to the principal.
In case of entity framework FK in dependent must also be its PK so in your case you should use:
public class Boo
{
[Key, ForeignKey("Foo")]
public string BooId{get;set;}
public Foo Foo{get;set;}
}
Or fluent mapping
modelBuilder.Entity<Foo>()
.HasOptional(f => f.Boo)
.WithRequired(s => s.Foo);
The easiest way to do this is just:
You will receive a float or double and want it to convert it to the closest round up then just do System.out.println((int)Math.ceil(yourfloat));
it'll work perfectly
