In bash version 4 associative arrays were introduced.
declare -A arr
arr["key1"]=val1
arr+=( ["key2"]=val2 ["key3"]=val3 )
The arr array now contains the three key value pairs. Bash is fairly limited what you can do with them though, no sorting or popping etc.
for key in ${!arr[@]}; do
echo ${key} ${arr[${key}]}
done
Will loop over all key values and echo them out.
Note: Bash 4 does not come with Mac OS X because of its GPLv3 license; you have to download and install it. For more on that see here
The essentials of your question are as follows.
Since you have Map
and User
models and you have defined ManyToManyField
in Map model, if you want to get access to members of the Map then you have the option of map_instance.members.all()
since you have defined members field.
However, say you want to access all maps a user is a part of then what option do you have.
By default, Django provided you with user_instance.modelname_set.all()
and this will translate to the user.map_set.all()
in this case.
maps is much better than map_set.
related_name provides you an ability to let Django know how you are going to access Map from User model or in general how you can access reverse models which is the whole point in creating ManyToMany fields and using ORM in that sense.
You can try in your main.xml
file:
android:selectAllOnFocus="true"
Or, in Java, use
editText.setSelectAllOnFocus(true);
assert
will terminate the program (usually with a message quoting the assert statement) if its argument turns out to be false. It's commonly used during debugging to make the program fail more obviously if an unexpected condition occurs.
For example:
assert(length >= 0); // die if length is negative.
You can also add a more informative message to be displayed if it fails like so:
assert(length >= 0 && "Whoops, length can't possibly be negative! (didn't we just check 10 lines ago?) Tell jsmith");
Or else like this:
assert(("Length can't possibly be negative! Tell jsmith", length >= 0));
When you're doing a release (non-debug) build, you can also remove the overhead of evaluating assert
statements by defining the NDEBUG
macro, usually with a compiler switch. The corollary of this is that your program should never rely on the assert macro running.
// BAD
assert(x++);
// GOOD
assert(x);
x++;
// Watch out! Depends on the function:
assert(foo());
// Here's a safer way:
int ret = foo();
assert(ret);
From the combination of the program calling abort() and not being guaranteed to do anything, asserts should only be used to test things that the developer has assumed rather than, for example, the user entering a number rather than a letter (which should be handled by other means).
Turns out, you can hide and show cells in a static UITableView - and with animation. And it is not that hard to accomplish.
The gist:
Use tableView:heightForRowAtIndexPath:
to specify cell heights dynamically based on some state.tableView.beginUpdates();tableView.endUpdates()
tableView.cellForRowAtIndexPath:
inside tableView:heightForRowAtIndexPath:
. Use cached indexPaths to differentiate the cells.Within MySQL work bench perform the following:
Click Server > Data Export
In the Object Selection Tab select the desired schema.
Next, select the desired tables using the list box to the right of the schema.
Select a file location to export the script.
Click Finish.
Navigate to the newly created file and copy the insert statements.
A lambda can only be converted to a function pointer if it does not capture, from the draft C++11 standard section 5.1.2
[expr.prim.lambda] says (emphasis mine):
The closure type for a lambda-expression with no lambda-capture has a public non-virtual non-explicit const conversion function to pointer to function having the same parameter and return types as the closure type’s function call operator. The value returned by this conversion function shall be the address of a function that, when invoked, has the same effect as invoking the closure type’s function call operator.
Note, cppreference also covers this in their section on Lambda functions.
So the following alternatives would work:
typedef bool(*DecisionFn)(int);
Decide greaterThanThree{ []( int x ){ return x > 3; } };
and so would this:
typedef bool(*DecisionFn)();
Decide greaterThanThree{ [](){ return true ; } };
and as 5gon12eder points out, you can also use std::function
, but note that std::function
is heavy weight, so it is not a cost-less trade-off.
Exactly what you need:) You can choose callback version or Promise version. Note that promises will work in IE only with Promise polyfill lib.You can put this code once on a page, and this function will appear in all your files.
The loadend event is fired when progress has stopped on the loading of a resource (e.g. after "error", "abort", or "load" have been dispatched)
Callback version
File.prototype.convertToBase64 = function(callback){
var reader = new FileReader();
reader.onloadend = function (e) {
callback(e.target.result, e.target.error);
};
reader.readAsDataURL(this);
};
$("#asd").on('change',function(){
var selectedFile = this.files[0];
selectedFile.convertToBase64(function(base64){
alert(base64);
})
});
Promise version
File.prototype.convertToBase64 = function(){
return new Promise(function(resolve, reject) {
var reader = new FileReader();
reader.onloadend = function (e) {
resolve({
fileName: this.name,
result: e.target.result,
error: e.target.error
});
};
reader.readAsDataURL(this);
}.bind(this));
};
FileList.prototype.convertAllToBase64 = function(regexp){
// empty regexp if not set
regexp = regexp || /.*/;
//making array from FileList
var filesArray = Array.prototype.slice.call(this);
var base64PromisesArray = filesArray.
filter(function(file){
return (regexp).test(file.name)
}).map(function(file){
return file.convertToBase64();
});
return Promise.all(base64PromisesArray);
};
$("#asd").on('change',function(){
//for one file
var selectedFile = this.files[0];
selectedFile.convertToBase64().
then(function(obj){
alert(obj.result);
});
});
//for all files that have file extention png, jpeg, jpg, gif
this.files.convertAllToBase64(/\.(png|jpeg|jpg|gif)$/i).then(function(objArray){
objArray.forEach(function(obj, i){
console.log("result[" + obj.fileName + "][" + i + "] = " + obj.result);
});
});
})

You can use String.Join
.
String.Join(
",",
Array.ConvertAll(
list.ToArray(),
element => element.ToString()
)
);
I got this error because I did not have the correct line in my build.gradle. I am using the org.apache.http.legacy.jar
library, which requires this:
android{
useLibrary 'org.apache.http.legacy'
...
}
So check that you have everything in your gradle file that is required.
Android Studio behaves weird in the case. Even though you set the JDK version in File -> Project Structure -> SDK Location, Android Studio only uses this for compiling the files. When it runs these files it, for some reason, looks at the PATH variable to find where java is installed.
If you have an older version of java installed on your system, then your PATH variable will be pointing to that older version of java.
So you have to set your PATH to point to the same version of java that have set in your Android studio project settings.
In your ~/.bashrc or corresponding profile file add this:
export PATH="/Applications/studio.app/Contents/jre/jdk/Contents/Home/bin:$PATH"
In my case my project was configured to use java 1.8, but my system wide installation of java was java 1.7. This was causing the issue.
You don't have to copy everything to C:\dotnet35. Usually all the files are already copied to the folder C:\Windows\WinSxS. Then the command becomes (assuming Windows was installed to C:): "Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:C:\Windows\WinSxS /LimitAccess" If not you can also point the command to the DVD directly. Then the command becomes (assuming DVD is mounted to D:): "Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:D:\sources\sxs /LimitAccess".
According to the documentation, timestamp
is a synonym for rowversion
- it's automatically generated and guaranteed1 to be unique. datetime
isn't - it's just a data type which handles dates and times, and can be client-specified on insert etc.
1 Assuming you use it properly, of course. See comments.
I think this example is good to check https://codepen.io/diegoleme/pen/surIK
I can quote code here
<form class="pure-form">
<fieldset>
<legend>Confirm password with HTML5</legend>
<input type="password" placeholder="Password" id="password" required>
<input type="password" placeholder="Confirm Password" id="confirm_password" required>
<button type="submit" class="pure-button pure-button-primary">Confirm</button>
</fieldset>
</form>
and
var password = document.getElementById("password")
, confirm_password = document.getElementById("confirm_password");
function validatePassword(){
if(password.value != confirm_password.value) {
confirm_password.setCustomValidity("Passwords Don't Match");
} else {
confirm_password.setCustomValidity('');
}
}
password.onchange = validatePassword;
confirm_password.onkeyup = validatePassword;
it's a bit late but...
your code will not work, because of list<FileInfo> lastUpdateFile = null;
and later lastUpdatedFile.Add(file);
so NullReference exception will be thrown.
Working version should be:
private List<FileInfo> GetLastUpdatedFileInDirectory(DirectoryInfo directoryInfo)
{
FileInfo[] files = directoryInfo.GetFiles();
List<FileInfo> lastUpdatedFile = new List<FileInfo>();
DateTime lastUpdate = DateTime.MinValue;
foreach (FileInfo file in files)
{
if (file.LastAccessTime > lastUpdate)
{
lastUpdatedFile.Add(file);
lastUpdate = file.LastAccessTime;
}
}
return lastUpdatedFile;
}

IF privileges are given to a user through some roles, then below SQL can be used
select * from ROLE_ROLE_PRIVS where ROLE = 'ROLE_NAME';
select * from ROLE_TAB_PRIVS where ROLE = 'ROLE_NAME';
select * from ROLE_SYS_PRIVS where ROLE = 'ROLE_NAME';
I've faced this today, and my issue was that my Content-Disposition
tag was wrongly set.
It looks like for both pdf
& application/x-zip-compressed
, you're supposed to set it to inline
instead of attachment
.
So to set your header, Java code would look like this:
...
String fileName = "myFileName.zip";
String contentDisposition = "attachment";
if ("application/pdf".equals(contentType)
|| "application/x-zip-compressed".equals(contentType)) {
contentDisposition = "inline";
}
response.addHeader("Content-Disposition", contentDisposition + "; filename=\"" + fileName + "\"");

The clean way to use mbstowcs
is to call it twice to find the length of the result:
const char * cs = <your input char*>
size_t wn = mbsrtowcs(NULL, &cs, 0, NULL);
// error if wn == size_t(-1)
wchar_t * buf = new wchar_t[wn + 1](); // value-initialize to 0 (see below)
wn = mbsrtowcs(buf, &cs, wn + 1, NULL);
// error if wn == size_t(-1)
assert(cs == NULL); // successful conversion
// result now in buf, return e.g. as std::wstring
delete[] buf;
Don't forget to call setlocale(LC_CTYPE, "");
at the beginning of your program!
The advantage over the Windows MultiByteToWideChar
is that this is entirely standard C, although on Windows you might prefer the Windows API function anyway.
I usually wrap this method, along with the opposite one, in two conversion functions string
->wstring
and wstring
->string
. If you also add trivial overloads string
->string
and wstring
->wstring
, you can easily write code that compiles with the Winapi TCHAR
typedef in any setting.
[Edit:] I added zero-initialization to buf
, in case you plan to use the C array directly. I would usually return the result as std::wstring(buf, wn)
, though, but do beware if you plan on using C-style null-terminated arrays.[/]
In a multithreaded environment you should pass a thread-local conversion state to the function as its final (currently invisible) parameter.
Here is a small rant of mine on this topic.
this is just as a side note, but generally what you want to do is keep size on the Session and ViewState small. I generally just store IDs and small amounts of packets in Session and ViewState.
for instance if you want to pass large chunks of data from one page to another, you can store an ID in the querystring and use that ID to either get data from a database or a file.
PS: but like I said, this might be totally unrelated to your query :)
dict((k, v) for (k, v) in points.iteritems() if v[0] < 5 and v[1] < 5)
in EXCEL 2013 i had to use IF function 2 times: 1st to identify error with ISERROR and 2nd to identify the specific type of error by ERROR.TYPE=3 in order to address this type of error. This way you can differentiate between error you want and other types.
user.dir
is the "User working directory" according to the Java Tutorial, System Properties
You can use the following
p{word-break: break-all;}

I think you misunderstood the concept of session, session is a server side per-user-data-store which allows you to save user data on the server side.
thus, you have 2 options, resort to use cookies, which will give the illusion of session(but not quite the same), you can access cookies very simply by document.cookie .
but, if you want your server be aware of the session, you need to use some sort of server request probably the best way is to use AJAX to do this.
I would recommend you to re-read the definition of sessions.
Had the same problem on another server, but realized that locales are messed.
export LC_ALL="en_US.UTF-8"
fixed the problem
For those who even yet have the problem, try enabling "Build project automatically" in the Java compiler settings and see if that makes a difference as it worked for me.
I've just used the following command:
SET LIN[ESIZE] 200
(from http://ss64.com/ora/syntax-sqlplus-set.html).
EDIT: For clarity, valid commands are SET LIN 200
or SET LINESIZE 200
.
This works fine, but you have to ensure your console window is wide enough. If you're using SQL Plus direct from MS Windows Command Prompt, the console window will automatically wrap the line at whatever the "Screen Buffer Size Width" property is set to, regardless of any SQL Plus LINESIZE
specification.
As suggested by @simplyharsh, you can also configure individual columns to display set widths, using COLUMN col_name FORMAT Ax
(where x is the desired length, in characters) - this is useful if you have one or two extra large columns and you just wish to show a summary of their values in the console screen.
I have to work in tcsh, and I know this is not an elegant solution, but for example, if I had to change folders to a path where one word is different, the whole thing can be done in the alias
a alias_name 'set a = `pwd`; set b = `echo $a | replace "Trees" "Tests"` ; cd $b'
If the path is always fixed, the just
a alias_name2 'cd path/you/always/need'
should work In the line above, the new folder path is set
parse_str($queryString, $vars);
unset($vars['return']);
$queryString = http_build_query($vars);
parse_str
parses a query string, http_build_query
creates a query string.
To reset the styles defined for legend
in bootstrap, you can do following in your css file:
legend {
all: unset;
}
Ref: https://css-tricks.com/almanac/properties/a/all/
The all property in CSS resets all of the selected element's properties, except the direction and unicode-bidi properties that control text direction.
Possible values are: initial
, inherit
& unset
.
Side note: clear
property is used in relation with float
(https://css-tricks.com/almanac/properties/c/clear/)
This should handle addition/subtraction, just put a negative value in to subtract and a positive value to add. This also solves the month crossover problem.
function monthAdd(date, month) {
var temp = date;
temp = new Date(date.getFullYear(), date.getMonth(), 1);
temp.setMonth(temp.getMonth() + (month + 1));
temp.setDate(temp.getDate() - 1);
if (date.getDate() < temp.getDate()) {
temp.setDate(date.getDate());
}
return temp;
}

$("#miscCategory").animate({scrollTop: $("#miscCategory").offset().top});
You can't mix tab and spaces for identation. Best practice is to convert all tabs to spaces.
How to fix this? Well just delete all the spaces/tabs before each line and convert them uniformly either to tabs OR spaces, but don't mix. Best solution: enable in your Editor the option to convert automagically any tabs to spaces.
Also be aware that your actual problem may lie in the lines before this block, and python throws the error here, because of a leading invalid indentation which doesn't match the following identations!
Looks like divs will not go outside of their body's width. Even within another div.
I threw this up to test (without a doctype though) and it does not work as thought.
.slideContainer {_x000D_
overflow-x: scroll;_x000D_
}_x000D_
.slide {_x000D_
float: left;_x000D_
}
_x000D_
<div class="slideContainer">_x000D_
<div class="slide" style="background: #f00">Some content Some content Some content Some content Some content Some content</div>_x000D_
<div class="slide" style="background: #ff0">More content More content More content More content More content More content</div>_x000D_
<div class="slide" style="background: #f0f">Even More content! Even More content! Even More content!</div>_x000D_
</div>
_x000D_
What i am thinking is that the inner div's could be loaded through an iFrame, since that is another page and its content could be very wide.
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'
If you use Microsoft.ApplicationBlocks.Data
it'll make calling your sprocs a single line
SqlHelper.ExecuteNonQuery(ConnectionString, "SprocName", DOB)
Oh and I think casperOne is correct...if you want to ensure the correct datetime over multiple timezones then simply convert the value to UTC before you send the value to SQL Server
SqlHelper.ExecuteNonQuery(ConnectionString, "SprocName", DOB.ToUniversalTime())
Or with Jackson:
String json = "...
ObjectMapper m = new ObjectMapper();
Set<Product> products = m.readValue(json, new TypeReference<Set<Product>>() {});
If you are searching for the index of the last occurrence of myvalue
in mylist
:
len(mylist) - mylist[::-1].index(myvalue) - 1
Different types to check the values exists
d = {"key1":"value1", "key2":"value2"}
"value10" in d.values()
>> False
What if list of values
test = {'key1': ['value4', 'value5', 'value6'], 'key2': ['value9'], 'key3': ['value6']}
"value4" in [x for v in test.values() for x in v]
>>True
What if list of values with string values
test = {'key1': ['value4', 'value5', 'value6'], 'key2': ['value9'], 'key3': ['value6'], 'key5':'value10'}
values = test.values()
"value10" in [x for v in test.values() for x in v] or 'value10' in values
>>True
If you by any chance wants to change the type of your collection you are better served with the Count()
extension. This way you don't have to refactor your code (to use Length
for instance).

You can try modifying this technique to suit your needs:
function isFunction() {
var functionName = window.prompt('Function name: ');
var isDefined = eval('(typeof ' + functionName + '==\'function\');');
if (isDefined)
eval(functionName + '();');
else
alert('Function ' + functionName + ' does not exist');
}
function anotherFunction() {
alert('message from another function.');
}
First make your template into a jQuery object:
var template = $("<li><div class='bar'>bla</div></li>");
Then set the attributes and append it to the DOM.
template.find('li').attr('id','1234');
$(document.body).append(template);
Note that it however makes no sense at all to add a li directly to the DOM since li should always be children of ul or ol. Also it is better to not make jQuery parse raw HTML. Instead create a li, set its attributes. Create a div and set it's attributes. Insert the div into the li and then append the li to the DOM.
Three ways you can do this - from the form designer, select the form, and where you normally see the list of properties, just above it there should be a little lightning symbol - this shows you all the events of the form. Find the form load event in the list, and you should be able to pick ProgramViwer_Load
from the dropdown.
A second way to do it is programmatically - somewhere (constructor maybe) you'd need to add it, something like: ProgramViwer.Load += new EventHandler(ProgramViwer_Load);
A third way using the designer (probably the quickest) - when you create a new form, double click on the middle of it on it in design mode. It'll create a Form load event for you, hook it in, and take you to the event handler code. Then you can just add your two lines and you're good to go!

Just Try it out, Looks a bit messy, but It works Even with the new Firefox Update for Yahoo mail. (doesn't center the email because replace the main table by a div)
In my case I have succeed with the following solution for converting field ClockInTime from ClockTime collection from string to Date type:
db.ClockTime.find().forEach(function(doc) {
doc.ClockInTime=new Date(doc.ClockInTime);
db.ClockTime.save(doc);
})
Quite recently they've added the depends_on
feature.
Edit:
As of compose version 2.1+ till version 3 you can use depends_on
in conjunction with healthcheck
to achieve this:
version: '2.1'
services:
web:
build: .
depends_on:
db:
condition: service_healthy
redis:
condition: service_started
redis:
image: redis
db:
image: redis
healthcheck:
test: "exit 0"
Before version 2.1
You can still use depends_on
, but it only effects the order in which services are started - not if they are ready before the dependant service is started.
It seems to require at least version 1.6.0.
Usage would look something like this:
version: '2'
services:
web:
build: .
depends_on:
- db
- redis
redis:
image: redis
db:
image: postgres
From the docs:
Express dependency between services, which has two effects:
- docker-compose up will start services in dependency order. In the following example, db and redis will be started before web.
- docker-compose up SERVICE will automatically include SERVICE’s dependencies. In the following example, docker-compose up web will also create and start db and redis.
Note: As I understand it, although this does set the order in which containers are loaded. It does not guarantee that the service inside the container has actually loaded.
For example, you postgres container might be up. But the postgres service itself might still be initializing within the container.
Another possibility is to select the Install Dependencies checkbox In the R package installer, on the bottom right:
A simple Swift 2.0 approach to making a HTTP GET request
The HTTP request is asynchronous so you need a way to get the returned value from the HTTP Request. This approach uses Notifiers and is spread over two classes.
The example is to check the username and password for an identifier token using the website http://www.example.com/handler.php?do=CheckUserJson&json= That is the file is called handler.php and has a switch statement on the do parameter to get a RESTful approach.
In the viewDidLoad we setup the NotifierObserver, set up the json and make the call to the getHTTPRequest function. It will return to the function checkedUsernameAndPassword with the returned parameter from the http request.
override func viewDidLoad() {
super.viewDidLoad()
// setup the Notification observer to catch the result of check username and password
NSNotificationCenter.defaultCenter().addObserver(self, selector: "checkedUsernameAndPassword:", name: CHECK_USERNAME_AND_PASSWORD, object: nil)
let username = GlobalVariables.USER_NAME
let password = GlobalVariables.PASSWORD
// check username and password
if let jsonString = Utility.checkUsernameAndPasswordJson(username, password:password){
print("json string returned = \(jsonString)")
let url = CHECKUSERJSON+jsonString
// CHECKUSERJSON = http://www.example.com/handler.php?do=CheckUserJson&json=
// jsonString = {\"username\":\"demo\",\"password\":\"demo\"}"
// the php script handles a json request and returns a string identifier
Utility.getHTTPRequest(url,notifierId: CHECK_USERNAME_AND_PASSWORD)
// the returned identifier is sent to the checkedUsernaeAndPassword function when it becomes availabel.
}
}
There are two static functions in Utility.swift first to encode the json and then to do the HTTP call.
static func checkUsernameAndPasswordJson(username: String, password: String) -> String?{
let para:NSMutableDictionary = NSMutableDictionary()
para.setValue("demo", forKey: "username")
para.setValue("demo", forKey: "password")
let jsonData: NSData
do{
jsonData = try NSJSONSerialization.dataWithJSONObject(para, options: NSJSONWritingOptions())
let jsonString = NSString(data: jsonData, encoding: NSUTF8StringEncoding) as! String
return jsonString
} catch _ {
print ("UH OOO")
return nil
}
}
and the Http request
static func getHTTPRequest (url:String , notifierId: String) -> Void{
let urlString = url
let config = NSURLSessionConfiguration.defaultSessionConfiguration()
let session = NSURLSession(configuration: config, delegate: nil, delegateQueue: nil)
let safeURL = urlString.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet())!
if let url = NSURL(string: safeURL){
let request = NSMutableURLRequest(URL: url)
request.HTTPMethod = "GET"
request.timeoutInterval = 60
let taskData = session.dataTaskWithRequest(request, completionHandler: {
(data:NSData?, response:NSURLResponse?, error:NSError?) -> Void in
if (data != nil) {
let result = NSString(data: data! , encoding: NSUTF8StringEncoding)
sendNotification (notifierId, message: String(result), num: 0)
}else{
sendNotification (notifierId, message: String(UTF8String: nil), num: -1) }
})
taskData.resume()
}else{
print("bad urlString = \(urlString)")
}
}
The sendNotification function completes the circle. Notice that in teh Observer there is a ":" at the end of the selector string. This allows the notification to carry a payload in userInfo. I give this a String and an Int.
static func sendNotification (key: String, message:String?, num: Int?){
NSNotificationCenter.defaultCenter().postNotificationName(
key,
object: nil,
userInfo: (["message": message!,
"num": "\(num!)"])
)
}
Note that using HTTP is oldFashioned, prefer HTTPS see How do I load an HTTP URL with App Transport Security enabled in iOS 9?
Check that the version number of your servlet-api.jar
is at least 3.0. There is a version number inside the jar in the META-INF/manifest.mf
file:
Implementation-Version: 3.0.1
If it's less than 3.0 download the 3.0.1 from Maven Central: http://search.maven.org/#artifactdetails|javax.servlet|javax.servlet-api|3.0.1|jar
Former servlet specifications (2.5, 2.4 etc.) do not support annotations.

Pseudo-elements are not part of the DOM, so they can't be manipulated using jQuery or Javascript.
But as pointed out in the accepted answer, you can use the JS to append a style block which ends of styling the pseudo-elements.
As of April 2018, Chrome (along with several other major browsers) now require the muted
attribute too.
Therefore, you should use
<video width="320" height="240" autoplay loop muted>
<source src="movie.mp4" type="video/mp4" />
</video>
eburgos, I've modified your code slightly because when you have multiple datatables in your dataset it was just overwriting them in the spreadsheet so you were only left with one sheet in the workbook. I basically just moved the part where the workbook is created out of the loop. Here is the updated code.
private void ExportDSToExcel(DataSet ds, string destination)
{
using (var workbook = SpreadsheetDocument.Create(destination, DocumentFormat.OpenXml.SpreadsheetDocumentType.Workbook))
{
var workbookPart = workbook.AddWorkbookPart();
workbook.WorkbookPart.Workbook = new DocumentFormat.OpenXml.Spreadsheet.Workbook();
workbook.WorkbookPart.Workbook.Sheets = new DocumentFormat.OpenXml.Spreadsheet.Sheets();
uint sheetId = 1;
foreach (DataTable table in ds.Tables)
{
var sheetPart = workbook.WorkbookPart.AddNewPart<WorksheetPart>();
var sheetData = new DocumentFormat.OpenXml.Spreadsheet.SheetData();
sheetPart.Worksheet = new DocumentFormat.OpenXml.Spreadsheet.Worksheet(sheetData);
DocumentFormat.OpenXml.Spreadsheet.Sheets sheets = workbook.WorkbookPart.Workbook.GetFirstChild<DocumentFormat.OpenXml.Spreadsheet.Sheets>();
string relationshipId = workbook.WorkbookPart.GetIdOfPart(sheetPart);
if (sheets.Elements<DocumentFormat.OpenXml.Spreadsheet.Sheet>().Count() > 0)
{
sheetId =
sheets.Elements<DocumentFormat.OpenXml.Spreadsheet.Sheet>().Select(s => s.SheetId.Value).Max() + 1;
}
DocumentFormat.OpenXml.Spreadsheet.Sheet sheet = new DocumentFormat.OpenXml.Spreadsheet.Sheet() { Id = relationshipId, SheetId = sheetId, Name = table.TableName };
sheets.Append(sheet);
DocumentFormat.OpenXml.Spreadsheet.Row headerRow = new DocumentFormat.OpenXml.Spreadsheet.Row();
List<String> columns = new List<string>();
foreach (DataColumn column in table.Columns)
{
columns.Add(column.ColumnName);
DocumentFormat.OpenXml.Spreadsheet.Cell cell = new DocumentFormat.OpenXml.Spreadsheet.Cell();
cell.DataType = DocumentFormat.OpenXml.Spreadsheet.CellValues.String;
cell.CellValue = new DocumentFormat.OpenXml.Spreadsheet.CellValue(column.ColumnName);
headerRow.AppendChild(cell);
}
sheetData.AppendChild(headerRow);
foreach (DataRow dsrow in table.Rows)
{
DocumentFormat.OpenXml.Spreadsheet.Row newRow = new DocumentFormat.OpenXml.Spreadsheet.Row();
foreach (String col in columns)
{
DocumentFormat.OpenXml.Spreadsheet.Cell cell = new DocumentFormat.OpenXml.Spreadsheet.Cell();
cell.DataType = DocumentFormat.OpenXml.Spreadsheet.CellValues.String;
cell.CellValue = new DocumentFormat.OpenXml.Spreadsheet.CellValue(dsrow[col].ToString()); //
newRow.AppendChild(cell);
}
sheetData.AppendChild(newRow);
}
}
}

For Tomcat 7 to increase memory :
Identify your service name, you will find it in the service properties, under the "Path to executable" at the end of the line
For me it is //RS//Tomcat70 so the name is Tomcat70
Then write as administrator :
tomcat7.exe //US//Tomcat70 --JvmOptions=-Xmx1024M
You need to initialize whatever members you have in your struct, e.g.:
struct MyStruct {
private:
int someInt_;
float someFloat_;
public:
MyStruct(): someInt_(0), someFloat_(1.0) {} // Initializer list will set appropriate values
};
In my case, I used the ssl
module to "workaround" the certification like so:
import ssl
ssl._create_default_https_context = ssl._create_unverified_context
Then to read your link content, you can use:
urllib.request.urlopen(urllink)
You can either cast Height as a decimal:
select cast(@height as decimal(10, 5))/10 as heightdecimal
or you place a decimal point in your value you are dividing by:
declare @height int
set @height = 1023
select @height/10.0 as heightdecimal
see sqlfiddle with an example
Alternatively you can use the lodash toPairs method:
const _ = require('lodash');
const map = new Map(_.toPairs({foo: 'bar'}));
First of all Arrays class is an utility class which contains no. of utility methods to operate on Arrays (thanks to Arrays class otherwise we would have needed to create our own methods to act on Array objects)
asList
method is one of the utility methods of Array
class ,it is static method thats why we can call this method by its class name (like Arrays.asList(T...a)
)ArrayList
object, it just returns a List reference to existing Array
object(so now after using asList
method, two references to existing Array
object gets created)List
object , may NOT work on this Array object using List
reference like
for example, Array
s size is fixed in length, hence you obviously can not add or remove elements from Array
object using this List
reference (like list.add(10)
or list.remove(10);
else it will throw UnsupportedOperationException)Array
s object ( as you are operating on existing Array object by using list reference)In first case you are creating a new Arraylist
object (in 2nd case only reference to existing Array object is created but not a new ArrayList
object) ,so now there are two different objects one is Array
object and another is ArrayList
object and no connection between them ( so changes in one object will not be reflected/affected in another object ( that is in case 2 Array
and Arraylist
are two different objects)
Integer [] ia = {1,2,3,4};
System.out.println("Array : "+Arrays.toString(ia));
List<Integer> list1 = new ArrayList<Integer>(Arrays.asList(ia)); // new ArrayList object is created , no connection between existing Array Object
list1.add(5);
list1.add(6);
list1.remove(0);
list1.remove(0);
System.out.println("list1 : "+list1);
System.out.println("Array : "+Arrays.toString(ia));
Integer [] ia = {1,2,3,4};
System.out.println("Array : "+Arrays.toString(ia));
List<Integer> list2 = Arrays.asList(ia); // creates only a (new ) List reference to existing Array object (and NOT a new ArrayList Object)
// list2.add(5); // it will throw java.lang.UnsupportedOperationException - invalid operation (as Array size is fixed)
list2.set(0,10); // making changes in existing Array object using List reference - valid
list2.set(1,11);
ia[2]=12; // making changes in existing Array object using Array reference - valid
System.out.println("list2 : "+list2);
System.out.println("Array : "+Arrays.toString(ia));
Override the values present in the outer UL with values in inner UL.
You can finish this with only a Single Class, Just add this on your class path.
This one is enough for Spring Boot, Spring Security, nothing else. :
@Component
@Order(Ordered.HIGHEST_PRECEDENCE)
public class MyCorsFilterConfig implements Filter {
@Override
public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
final HttpServletResponse response = (HttpServletResponse) res;
response.setHeader("Access-Control-Allow-Origin", "*");
response.setHeader("Access-Control-Allow-Methods", "POST, PUT, GET, OPTIONS, DELETE");
response.setHeader("Access-Control-Allow-Headers", "Authorization, Content-Type, enctype");
response.setHeader("Access-Control-Max-Age", "3600");
if (HttpMethod.OPTIONS.name().equalsIgnoreCase(((HttpServletRequest) req).getMethod())) {
response.setStatus(HttpServletResponse.SC_OK);
} else {
chain.doFilter(req, res);
}
}
@Override
public void destroy() {
}
@Override
public void init(FilterConfig config) throws ServletException {
}
}
This is 2 step process
If you want to push your branch code to remote repo then do
Alternative solution, where you can have the database in the folder you want inside the solution. That worked for me:
.ConnectionString(@"Data Source=LocalDB)\MSSQLLocalDB;
AttachDbFilename="+AppDomain.CurrentDomain.BaseDirectory+"Folder1\\Folder2\\SampleDatabase.mdf" + ";
Integrated Security=True;")
Try to remove armv7s from project's "Valid architecture" to release from this issue for iOS 5.1 phone
A more reliable alternative to NSNotification
is to add yourself as observer to player's rate
property.
[self.player addObserver:self
forKeyPath:@"rate"
options:NSKeyValueObservingOptionNew
context:NULL];
Then check if the new value for observed rate is zero, which means that playback has stopped for some reason, like reaching the end or stalling because of empty buffer.
- (void)observeValueForKeyPath:(NSString *)keyPath
ofObject:(id)object
change:(NSDictionary<NSString *,id> *)change
context:(void *)context {
if ([keyPath isEqualToString:@"rate"]) {
float rate = [change[NSKeyValueChangeNewKey] floatValue];
if (rate == 0.0) {
// Playback stopped
} else if (rate == 1.0) {
// Normal playback
} else if (rate == -1.0) {
// Reverse playback
}
}
}
For rate == 0.0
case, to know what exactly caused the playback to stop, you can do the following checks:
if (self.player.error != nil) {
// Playback failed
}
if (CMTimeGetSeconds(self.player.currentTime) >=
CMTimeGetSeconds(self.player.currentItem.duration)) {
// Playback reached end
} else if (!self.player.currentItem.playbackLikelyToKeepUp) {
// Not ready to play, wait until enough data is loaded
}
And don't forget to make your player stop when it reaches the end:
self.player.actionAtItemEnd = AVPlayerActionAtItemEndPause;
I did a kind of terminal emulator with Bootstrap
and Javascript
because I needed some dynamic to add easily new items, and I put the prompt from Javascript
.
HTML
:
<div class="panel panel-default">
<div class="panel-heading">Comandos SQL ejecutados</div>
<div class="panel-body panel-terminal-body">
<ul id="ulCommand"></ul>
</div>
</div>
Javascript
:
function addCommand(command){
//Creating the li tag
var li = document.createElement('li');
//Creating the img tag
var prompt = document.createElement('img');
//Setting the image
prompt.setAttribute('src','./lib/custom/img/terminal-prompt-white.png');
//Setting the width (like the font)
prompt.setAttribute('width','15px');
//Setting height as auto
prompt.setAttribute('height','auto');
//Adding the prompt to the list item
li.appendChild(prompt);
//Creating a span tag to add the command
//li.appendChild('el comando'); por que no es un nodo
var span = document.createElement('span');
//Adding the text to the span tag
span.innerHTML = command;
//Adding the span to the list item
li.appendChild(span);
//At the end, adding the list item to the list (ul)
document.getElementById('ulCommand').appendChild(li);
}
CSS
:
.panel-terminal-body {
background-color: #423F3F;
color: #EDEDED;
padding-left: 50px;
padding-right: 50px;
padding-top: 15px;
padding-bottom: 15px;
height: 300px;
}
.panel-terminal-body ul {
list-style: none;
}
I hope this help you.
Easiest thing is input it as a "div" give it a "margin:0 auto " but if you want it to be centered u need to give it a width
Div{
Margin: 0 auto ;
Width: 100px ;
}

As BalausC mentioned in a comment, you are probably looking for CSS (Cascading Style Sheets) not HTML attributes.
To position an element, a <table>
in your case you want to use either padding or margins.
the difference between margins and paddings can be seen as the "box model":
Image from HTML Dog article on margins and padding http://www.htmldog.com/guides/cssbeginner/margins/.
I highly recommend the article above if you need to learn how to use CSS.
To move the table down and right I would use margins like so:
table{
margin:25px 0 0 25px;
}
This is in shorthand so the margins are as follows:
margin: top right bottom left;
If the component is an EJB, then, there shouldn't be a problem injecting an EM.
But....In JBoss 5, the JAX-RS integration isn't great. If you have an EJB, you cannot use scanning and you must manually list in the context-param resteasy.jndi.resource. If you still have scanning on, Resteasy will scan for the resource class and register it as a vanilla JAX-RS service and handle the lifecycle.
This is probably the problem.
Database class that checks if there is any existing database instance it will return previous instance.
class Database {
public static $instance;
public static function getInstance(){
if(!isset(Database::$instance) ) {
Database::$instance = new Database();
}
return Database::$instance;
}
private function __cunstruct() {
/* private and cant create multiple objects */
}
public function getQuery(){
return "Test Query Data";
}
}
$dbObj = Database::getInstance();
$dbObj2 = Database::getInstance();
var_dump($dbObj);
var_dump($dbObj2);
/*
After execution you will get following output:
object(Database)[1]
object(Database)[1]

Kubernetes is an open source project that brings 'Google style' cluster management capabilities to the world of virtual machines, or 'on the metal' scenarios. It works very well with modern operating system environments (like CoreOS or Red Hat Atomic) that offer up lightweight computing 'nodes' that are managed for you. It is written in Golang and is lightweight, modular, portable and extensible. We (the Kubernetes team) are working with a number of different technology companies (including Mesosphere who curate the Mesos open source project) to establish Kubernetes as the standard way to interact with computing clusters. The idea is to reproduce the patterns that we see people needing to build cluster applications based on our experience at Google. Some of these concepts include:
So with Kubernetes alone you will have something that is simple, easy to get up-and-running, portable and extensible that adds 'cluster' as a noun to the things that you manage in the lightest weight manner possible. Run an application on a cluster, and stop worrying about an individual machine. In this case, cluster is a flexible resource just like a VM. It is a logical computing unit. Turn it up, use it, resize it, turn it down quickly and easily.
With Mesos, there is a fair amount of overlap in terms of the basic vision, but the products are at quite different points in their lifecycle and have different sweet spots. Mesos is a distributed systems kernel that stitches together a lot of different machines into a logical computer. It was born for a world where you own a lot of physical resources to create a big static computing cluster. The great thing about it is that lots of modern scalable data processing application run well on Mesos (Hadoop, Kafka, Spark) and it is nice because you can run them all on the same basic resource pool, along with your new age container packaged apps. It is somewhat more heavy weight than the Kubernetes project, but is getting easier and easier to manage thanks to the work of folks like Mesosphere.
Now what gets really interesting is that Mesos is currently being adapted to add a lot of the Kubernetes concepts and to support the Kubernetes API. So it will be a gateway to getting more capabilities for your Kubernetes app (high availability master, more advanced scheduling semantics, ability to scale to a very large number of nodes) if you need them, and is well suited to run production workloads (Kubernetes is still in an alpha state).
When asked, I tend to say:
Kubernetes is a great place to start if you are new to the clustering world; it is the quickest, easiest and lightest way to kick the tires and start experimenting with cluster oriented development. It offers a very high level of portability since it is being supported by a lot of different providers (Microsoft, IBM, Red Hat, CoreOs, MesoSphere, VMWare, etc).
If you have existing workloads (Hadoop, Spark, Kafka, etc), Mesos gives you a framework that let's you interleave those workloads with each other, and mix in a some of the new stuff including Kubernetes apps.
Mesos gives you an escape valve if you need capabilities that are not yet implemented by the community in the Kubernetes framework.
Apache Jackrabbit uses the ISO 8601 format for persisting dates, and there is a helper class to parse them:
org.apache.jackrabbit.util.ISO8601
Comes with jackrabbit-jcr-commons.
For isolated projects, where dependencies must be kept to a minimum, I found myself using this implementation:
var arguments = uri.Query
.Substring(1) // Remove '?'
.Split('&')
.Select(q => q.Split('='))
.ToDictionary(q => q.FirstOrDefault(), q => q.Skip(1).FirstOrDefault());
Do note, however, that I do not handle encoded strings of any kind, as I was using this in a controlled setting, where encoding issues would be a coding error on the server side that should be fixed.
You can use COALESCE
in conjunction with NULLIF
for a short, efficient solution:
COALESCE( NULLIF(yourField,'') , '0' )
The NULLIF
function will return null if yourField
is equal to the second value (''
in the example), making the COALESCE
function fully working on all cases:
QUERY | RESULT
---------------------------------------------------------------------------------
SELECT COALESCE(NULLIF(null ,''),'0') | '0'
SELECT COALESCE(NULLIF('' ,''),'0') | '0'
SELECT COALESCE(NULLIF('foo' ,''),'0') | 'foo'

if not working in 4.0 then add:
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
The first one .clear();
will keep the same list just clear the list.
The second one new ArrayList<Integer>();
creates a new ArrayList
in memory.
Suggestion: First one because that's what is is designed to do.
Here's a slightly different way:

The correct way to hide title/label of ToolBar the following codes:
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setTitle(null);
I just created a simple timer using the MVP pattern (however it may be overkill for that simple project). It has quit, start/pause and a stop button. Time is displayed in HH:MM:SS format. Time counting is implemented using a thread that is running several times a second and the difference between the time the timer has started and the current time.
This is an ultimate solution to set the border color of a TextBox:
public class BorderedTextBox : UserControl
{
TextBox textBox;
public BorderedTextBox()
{
textBox = new TextBox()
{
BorderStyle = BorderStyle.FixedSingle,
Location = new Point(-1, -1),
Anchor = AnchorStyles.Top | AnchorStyles.Bottom |
AnchorStyles.Left | AnchorStyles.Right
};
Control container = new ContainerControl()
{
Dock = DockStyle.Fill,
Padding = new Padding(-1)
};
container.Controls.Add(textBox);
this.Controls.Add(container);
DefaultBorderColor = SystemColors.ControlDark;
FocusedBorderColor = Color.Red;
BackColor = DefaultBorderColor;
Padding = new Padding(1);
Size = textBox.Size;
}
public Color DefaultBorderColor { get; set; }
public Color FocusedBorderColor { get; set; }
public override string Text
{
get { return textBox.Text; }
set { textBox.Text = value; }
}
protected override void OnEnter(EventArgs e)
{
BackColor = FocusedBorderColor;
base.OnEnter(e);
}
protected override void OnLeave(EventArgs e)
{
BackColor = DefaultBorderColor;
base.OnLeave(e);
}
protected override void SetBoundsCore(int x, int y,

This issue happened to me where one of my dependent libraries was compiling a DLL with "Any CPU" when the parent library was expecting a compilation of "x64".
What? The person asked for Linux specific, and the equivalent of getpid(). Not BSD or Apple. The answer is gettid() and returns an integral type. You will have to call it using syscall(), like this:
#include <sys/types.h>
#include <unistd.h>
#include <sys/syscall.h>
....
pid_t x = syscall(__NR_gettid);
While this may not be portable to non-linux systems, the threadid is directly comparable and very fast to acquire. It can be printed (such as for LOGs) like a normal integer.
you can get it from here https://slproweb.com/products/Win32OpenSSL.html

No technical tips here, just simple adjustments of the preferences of VsCode.
I managed to show code folding controls always in VsCode by going to Preferences and searching for 'folding'. Now just select to always show these controls. This works with the Typescript code and HTML of templates in the Angular 8 solution I tested it with.
This was tested with VsCode Insiders 1.37.0 running on a Windows 10 OS.
It is basically a comment. As we know, a number of people working on the same project must have knowledge about the code changes. We are making some notes in the program about the parameters.
If you have IIS Express (with Visual Studio):
To enable the SSL within IIS Express, you have to just set “SSL Enabled = true” in the project properties window.
See the steps and pictures at this code project.
IIS Express will generate a certificate for you (you'll be prompted for it, etc.). Note that depending on configuration the site may still automatically start with the URL rather than the SSL URL. You can see the SSL URL - note the port number and replace it in your browser address bar, you should be able to get in and test.
From there you can right click on your project, click property pages, then start options and assign the start URL - put the new https with the new port (usually 44301 - notice the similarity to port 443) and your project will start correctly from then on.
I wrestled with this for some time. The problem lies not in how to load the data, but how to construct the table to hold it. You must generate a DDL statement to build the table before importing the data.
Particularly difficult if the table has a large number of columns.
Here's a python script that (almost) does the job:
#!/usr/bin/python
import sys
import csv
# get file name (and hence table name) from command line
# exit with usage if no suitable argument
if len(sys.argv) < 2:
sys.exit('Usage: ' + sys.argv[0] + ': input CSV filename')
ifile = sys.argv[1]
# emit the standard invocation
print 'create table ' + ifile + ' ('
with open(ifile + '.csv') as inputfile:
reader = csv.DictReader(inputfile)
for row in reader:
k = row.keys()
for item in k:
print '`' + item + '` TEXT,'
break

The problem it leaves to solve is that the final field name and data type declaration is terminated with a comma, and the mySQL parser won't tolerate that.
Of course it also has the problem that it uses the TEXT data type for every field. If the table has several hundred columns, then VARCHAR(64) will make the table too large.
This also seems to break at the maximum column count for mySQL. That's when it's time to move to Hive or HBase if you are able.
You could simply go to phpmyadmin.conf file and change "deny from all" to "allow from all". Well it worked for me, hope it works for you as well.
sort -nk2 file.txt
Accordingly you can change column number.
A simple step to understand what is java and core java.
Find a book for Java.
Find a book for core java.
Compare the content of both books.
Actual result: both have almost same content.
Result: Java and core java is same.
core java is just slang, to emphasize on deep knowledge of basic java. but if I say I know Java it doesn't mean that I don't have deep knowledge of basic java, or if I know everything in java.

With kotlin and Gson we can do it more easily:
implementation "com.squareup.retrofit2:converter-gson:2.3.0"
kotlin
file, add the following methodsimport com.google.gson.Gson import com.google.gson.reflect.TypeToken fun <T> Gson.convertToJsonString(t: T): String { return toJson(t).toString() } fun <T> Gson.convertToModel(jsonString: String, cls: Class<T>): T? { return try { fromJson(jsonString, cls) } catch (e: Exception) { null } } inline fun <reified T> Gson.fromJson(json: String) = this.fromJson<T>(json, object: TypeToken<T>() {}.type)
Note: Do not add declare class, just add these methods, everything will work fine.
create a reference of gson:
val gson=Gson()
To convert array to json string, call:
val jsonString=gson.convertToJsonString(arrayList)
To get array from json string, call:
val arrayList=gson.fromJson<ArrayList<YourModelClassName>>(jsonString)
To convert a model to json string, call:
val jsonString=gson.convertToJsonString(model)
To convert json string to model, call:

I was not satisfied with @Abhrabm answer because:
It was only preventing negative numbers from being entered from up/down arrows, whereas user can type negative number from keyboard.
Solution is to prevent with key code:
// Select your input element._x000D_
var number = document.getElementById('number');_x000D_
_x000D_
// Listen for input event on numInput._x000D_
number.onkeydown = function(e) {_x000D_
if(!((e.keyCode > 95 && e.keyCode < 106)_x000D_
|| (e.keyCode > 47 && e.keyCode < 58) _x000D_
|| e.keyCode == 8)) {_x000D_
return false;_x000D_
}_x000D_
}
_x000D_
<form action="" method="post">_x000D_
<input type="number" id="number" min="0" />_x000D_
<input type="submit" value="Click me!"/>_x000D_
</form>
_x000D_
Clarification provided by @Hugh Guiney:
What key codes are being checked:
So this script is preventing invalid key from being entered in input.
This gets part way there. There is no ActualFontSize property but there is an ActualHeight and that would relate to the FontSize. Right now this only sizes for the original render. I could not figure out how to register the Converter as resize event. Actually maybe need to register the FontSize as a resize event. Please don't mark me down for an incomplete answer. I could not put code sample in a comment.

Dupx
Dupx is a simple *nix utility to redirect standard output/input/error of an already running process.
Motivation
I've often found myself in a situation where a process I started on a remote system via SSH takes much longer than I had anticipated. I need to break the SSH connection, but if I do so, the process will die if it tries to write something on stdout/error of a broken pipe. I wish I could suspend the process with ^Z and then do a
bg %1 >/tmp/stdout 2>/tmp/stderr
Unfortunately this will not work (in shells I know).
As said in previous answers the 'normal' way is to add it to a JScrollPane, but sometimes you don't want it to scroll (don't ask me when:)). Then you can add the TableHeader yourself. Like this:
JPanel tablePanel = new JPanel(new BorderLayout());
JTable table = new JTable();
tablePanel.add(table, BorderLayout.CENTER);
tablePanel.add(table.getTableHeader(), BorderLayout.NORTH);
printf() doesn't directly support that. Instead you have to make your own function.
Something like:
while (n) {
if (n & 1)
printf("1");
else
printf("0");
n >>= 1;
}
printf("\n");
This answer should be enough to get you set up to follow this tutorial on Building a functional search component with MongoDB, Elasticsearch, and AngularJS.
If you're looking to use faceted search with data from an API then Matthiasn's BirdWatch Repo is something you might want to look at.
So here's how you can setup a single node Elasticsearch "cluster" to index MongoDB for use in a NodeJS, Express app on a fresh EC2 Ubuntu 14.04 instance.
Make sure everything is up to date.
sudo apt-get update
Install NodeJS.
sudo apt-get install nodejs
sudo apt-get install npm
Install MongoDB - These steps are straight from MongoDB docs. Choose whatever version you're comfortable with. I'm sticking with v2.4.9 because it seems to be the most recent version MongoDB-River supports without issues.
Import the MongoDB public GPG Key.
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10
Update your sources list.
echo 'deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen' | sudo tee /etc/apt/sources.list.d/mongodb.list
Get the 10gen package.
sudo apt-get install mongodb-10gen
Then pick your version if you don't want the most recent. If you are setting your environment up on a windows 7 or 8 machine stay away from v2.6 until they work some bugs out with running it as a service.
apt-get install mongodb-10gen=2.4.9
Prevent the version of your MongoDB installation being bumped up when you update.
echo "mongodb-10gen hold" | sudo dpkg --set-selections
Start the MongoDB service.
sudo service mongodb start
Your database files default to /var/lib/mongo and your log files to /var/log/mongo.
Create a database through the mongo shell and push some dummy data into it.
mongo YOUR_DATABASE_NAME
db.createCollection(YOUR_COLLECTION_NAME)
for (var i = 1; i <= 25; i++) db.YOUR_COLLECTION_NAME.insert( { x : i } )
Now to Convert the standalone MongoDB into a Replica Set.
First Shutdown the process.
mongo YOUR_DATABASE_NAME
use admin
db.shutdownServer()
Now we're running MongoDB as a service, so we don't pass in the "--replSet rs0" option in the command line argument when we restart the mongod process. Instead, we put it in the mongod.conf file.
vi /etc/mongod.conf
Add these lines, subbing for your db and log paths.
replSet=rs0
dbpath=YOUR_PATH_TO_DATA/DB
logpath=YOUR_PATH_TO_LOG/MONGO.LOG
Now open up the mongo shell again to initialize the replica set.
mongo DATABASE_NAME
config = { "_id" : "rs0", "members" : [ { "_id" : 0, "host" : "127.0.0.1:27017" } ] }
rs.initiate(config)
rs.slaveOk() // allows read operations to run on secondary members.
Now install Elasticsearch. I'm just following this helpful Gist.
Make sure Java is installed.
sudo apt-get install openjdk-7-jre-headless -y
Stick with v1.1.x for now until the Mongo-River plugin bug gets fixed in v1.2.1.
wget https://download.elasticsearch.org/elasticsearch/elasticsearch/elasticsearch-1.1.1.deb
sudo dpkg -i elasticsearch-1.1.1.deb
curl -L http://github.com/elasticsearch/elasticsearch-servicewrapper/tarball/master | tar -xz
sudo mv *servicewrapper*/service /usr/local/share/elasticsearch/bin/
sudo rm -Rf *servicewrapper*
sudo /usr/local/share/elasticsearch/bin/service/elasticsearch install
sudo ln -s `readlink -f /usr/local/share/elasticsearch/bin/service/elasticsearch` /usr/local/bin/rcelasticsearch
Make sure /etc/elasticsearch/elasticsearch.yml has the following config options enabled if you're only developing on a single node for now:
cluster.name: "MY_CLUSTER_NAME"
node.local: true
Start the Elasticsearch service.
sudo service elasticsearch start
Verify it's working.
curl http://localhost:9200
If you see something like this then you're good.
{
"status" : 200,
"name" : "Chi Demon",
"version" : {
"number" : "1.1.2",
"build_hash" : "e511f7b28b77c4d99175905fac65bffbf4c80cf7",
"build_timestamp" : "2014-05-22T12:27:39Z",
"build_snapshot" : false,
"lucene_version" : "4.7"
},
"tagline" : "You Know, for Search"
}
Now install the Elasticsearch plugins so it can play with MongoDB.
bin/plugin --install com.github.richardwilly98.elasticsearch/elasticsearch-river-mongodb/1.6.0
bin/plugin --install elasticsearch/elasticsearch-mapper-attachments/1.6.0
These two plugins aren't necessary but they're good for testing queries and visualizing changes to your indexes.
bin/plugin --install mobz/elasticsearch-head
bin/plugin --install lukas-vlcek/bigdesk
Restart Elasticsearch.
sudo service elasticsearch restart
Finally index a collection from MongoDB.
curl -XPUT localhost:9200/_river/DATABASE_NAME/_meta -d '{
"type": "mongodb",
"mongodb": {
"servers": [
{ "host": "127.0.0.1", "port": 27017 }
],
"db": "DATABASE_NAME",
"collection": "ACTUAL_COLLECTION_NAME",
"options": { "secondary_read_preference": true },
"gridfs": false
},
"index": {
"name": "ARBITRARY INDEX NAME",
"type": "ARBITRARY TYPE NAME"
}
}'
Check that your index is in Elasticsearch
curl -XGET http://localhost:9200/_aliases
Check your cluster health.
curl -XGET 'http://localhost:9200/_cluster/health?pretty=true'
It's probably yellow with some unassigned shards. We have to tell Elasticsearch what we want to work with.
curl -XPUT 'localhost:9200/_settings' -d '{ "index" : { "number_of_replicas" : 0 } }'
Check cluster health again. It should be green now.
curl -XGET 'http://localhost:9200/_cluster/health?pretty=true'
Go play.
This might not be a suitable solution for the console, but Rails has a method for this problem: Logger#silence
ActiveRecord::Base.logger.silence do
# the stuff you want to be silenced
end
I have found the answer to my question.
client.DefaultRequestHeaders.Add("X-Version","1");
That should add a custom header to your request
Instead of explicitly defining the path to the interpreter as in /usr/bin/bash/
, by using the env command, the interpreter is searched for and launched from wherever it is first found. This has both upsides and downsides
I'm no c++ guy, but you should be able to get the gist from this.
public static string Reverse(string s) {
if (s == null || s.Length < 2) {
return s;
}
int length = s.Length;
int loop = (length >> 1) + 1;
int j;
char[] chars = new char[length];
for (int i = 0; i < loop; i++) {
j = length - i - 1;
chars[i] = s[j];
chars[j] = s[i];
}
return new string(chars);
}
You really want to use at. It is exactly made for this purpose.
echo /usr/bin/the_command options | at now + 1 day
However if you don't have at, or your hosting company doesn't provide access to it, you could make a self-deleting cron entry.
Sadly, this will remove all your cron entries. However, if you only have one, this is fine.
0 0 2 12 * crontab -r ; /home/adm/bin/the_command options
The command crontab -r
removes your crontab entry. Luckily the rest of the command line will still execute.
WARNING: This is dangerous! It removes ALL cron entries. If you have many, this will remove them all, not just the one that has the "crontab -r" line!
public static String reverseIt(String source) {
int i, len = source.length();

}
return dest.toString();

I have found that ASCII 12 make a Form feed, that is a new page. here is a wikipedia definition
"Form feed is a page-breaking ASCII control character. It forces the printer to eject the current page and to continue printing at the top of another"
The code is
Serial.write(12);
Arduino Terminate doesn't support the character but Putty a light open source telnet client can do it
An Example of the code
void setup() {
Serial.begin(9600);//Initializase the serial transmiter speed
}
void loop() {
//Code tested with Putty terminal
Serial.write(12);//ASCII for a Form feed
Serial.println("This is the title of a new page");// your code
delay(500);//delay for visual
}
As you say, local variables and references are stored on the stack. When a method returns, the stack pointer is simply moved back to where it was before the method started, that is, all local data is "removed from the stack". Therefore, there is no garbage collection needed on the stack, that only happens in the heap.
To answer your specific questions:
In 32 bit format system the hexadecimal value 0xff
represents 00000000000000000000000011111111
that is 255(15*16^1+15*16^0)
in decimal. and the bitwise & operator masks the same 8 right most bits as in first operand.
You need the textFX plugin. Then, just follow these instructions:
Paste the text into Notepad++ (CTRL+V). ...
Mark all the text (CTRL+A). ...
Click TextFX ? Click TextFX Tools ? Click Sort lines case insensitive (at column)
Duplicates and blank lines have been removed and the data has been sorted alphabetically.
Personally, I would use sort -i -u source >dest instead of notepad++
Might as well throw up an actual response with my solution, which was inspired by Peter Liljenberg's:
$ mpstat | awk '$12 ~ /[0-9.]+/ { print 100 - $12"%" }'
0.75%
This will use awk
to print out 100 minus the 12th field (idle), with a percentage sign after it. awk
will only do this for a line where the 12th field has numbers and dots only ($12 ~ /[0-9]+/
).
You can also average five samples, one second apart:
$ mpstat 1 5 | awk 'END{print 100-$NF"%"}'
Test it like this:
$ mpstat 1 5 | tee /dev/tty | awk 'END{print 100-$NF"%"}'
Check this code. It gives you the clear solution of JSON parse error. It commonly happen by the newlines and the space between json key start and json key end
data_val = data_val.replace(/[\n\s]{1,}\"/g, "\"")
.replace(/\"[\n\s]{1,}/g, "\"")
.replace(/[\n]/g, "\\n")
$('#checkbox').prop('checked', true);
When you want it unchecked:
$('#checkbox').prop('checked', false);
Using instring function :)
select Value,
substring(String,1,instr(String," ") -1) Fname,
substring(String,instr(String,",") +1) Sname
from tablename;
Used two functions,
1. substring(string, position, length)
==> returns string from positon to length
2. instr(string,pattern)
==> returns position of pattern.
If we don’t provide length argument in substring it returns until end of string

This solution is for windows:
Do you really write exception safe code? [There's no such thing. Exceptions are a paper shield to errors unless you have a managed environment. This applies to first three questions.]
Do you know and/or actually use alternatives that work? [Alternative to what? The problem here is people don't separate actual errors from normal program operation. If it's normal program operation (ie a file not found), it's not really error handling. If it's an actual error, there is no way to 'handle' it or it's not an actual error. Your goal here is to find out what went wrong and either stop the spreadsheet and log an error, restart the driver to your toaster, or just pray that the jetfighter can continue flying even when it's software is buggy and hope for the best.]

This answer is specific to x86. Portable tools that can disassemble AArch64, MIPS, or whatever machine code include objdump
and llvm-objdump
.
Agner Fog's disassembler, objconv
, is quite nice. It will add comments to the disassembly output for performance problems (like the dreaded LCP stall from instructions with 16bit immediate constants, for example).
objconv -fyasm a.out /dev/stdout | less
(It doesn't recognize -
as shorthand for stdout, and defaults to outputting to a file of similar name to the input file, with .asm
tacked on.)
It also adds branch targets to the code. Other disassemblers usually disassemble jump instructions with just a numeric destination, and don't put any marker at a branch target to help you find the top of loops and so on.
It also indicates NOPs more clearly than other disassemblers (making it clear when there's padding, rather than disassembling it as just another instruction.)
It's open source, and easy to compile for Linux. It can disassemble into NASM, YASM, MASM, or GNU (AT&T) syntax.
Sample output:

Note that this output is ready to be assembled back into an object file, so you can tweak the code at the asm source level, rather than with a hex-editor on the machine code. (So you aren't limited to keeping things the same size.) With no changes, the result should be near-identical. It might not be, though, since disassembly of stuff like

doesn't have anything in the source to make sure it assembles to the longer encoding that leaves room for relocations to rewrite it with a 32bit offset.
If you don't want to install it objconv, GNU binutils objdump -Mintel -d
is very usable, and will already be installed if you have a normal Linux gcc setup.
Here's some sample code. This worked for me.
<LinearLayout
android:gravity="center"
>
<TextView
android:layout_gravity="center"
/>
<Button
android:layout_gravity="center"
/>
</LinearLayout>
So you're designing the Linear Layout to place all its contents (TextView and Button) in its center, and then the TextView and Button are placed relative to the center of the Linear Layout.

is a good habit and I suggest you go for that instead.
For your example where your objects are String
s you should be fine without anything else.
I.e. System.out.println(map)
would print exactly what you need without any extra code
0.0.0.0/0
for all IPv4 addresses
::0/0
for all IPv6 addresses
all
to match any IP address
samehost
to match any of the server's own IP addresses
samenet
to match any address in any subnet that the server is directly connected to.
e.g.
host all all 0.0.0.0/0 md5
You have to escape [
and ]
.
Try this:
$('.button').click(function(){
var fieldID = $(this).prev().attr("id");
fieldID = fieldID.replace(/([\[\]]+)/g, "\\$1");
$('#' + fieldID).val("hello world");
});
You can make use of bitwise AND operator &
.
Let's see below:
x = [1, 2, 3, 4, 5, 6, 7]
y = [i for i in x if i&1]
>>>
[1, 3, 5, 7]
Bitwise AND operator is used with 1, and the reason it works because, odd number when written in binary must have its first digit as 1. Let's check
23 = 1 * (2**4) + 0 * (2**3) + 1 * (2**2) + 1 * (2**1) + 1 * (2**0) = 10111
14 = 1 * (2**3) + 1 * (2**2) + 1 * (2**1) + 0 * (2**0) = 1110
AND operation with 1 will only return 1 (1 in binary will also have last digit 1), iff the value is odd.
Check the Python Bitwise Operator page for more.
P.S: You can tactically use this method if you want to select odd and even columns in a dataframe. Let's say x and y coordinates of facial key-points are given as columns x1, y1, x2, etc... To normalize the x and y coordinates with width and height values of each image you can simply perform
for i in range(df.shape[1]):
if i&1:
df.iloc[:, i] /= heights
else:
df.iloc[:, i] /= widths
This is not exactly related to the question but for data scientists and computer vision engineers this method could be useful.
Cheers!
Update: To create a popup menu in android with Kotlin refer my answer here.
To create a popup menu in android with Java:
Create a layout file activity_main.xml
under res/layout
directory which contains only one button.
Filename: activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="62dp"
android:layout_marginTop="50dp"
android:text="Show Popup" />
</RelativeLayout>
Create a file popup_menu.xml
under res/menu
directory
It contains three items as shown below.
Filename: poupup_menu.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="@+id/one"
android:title="One"/>
<item
android:id="@+id/two"
android:title="Two"/>
<item
android:id="@+id/three"
android:title="Three"/>
</menu>
MainActivity class which displays the popup menu on button click.
Filename: MainActivity.java
public class MainActivity extends Activity {
private Button button1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
//Creating the instance of PopupMenu
PopupMenu popup = new PopupMenu(MainActivity.this, button1);
//Inflating the Popup using xml file
popup.getMenuInflater()
.inflate(R.menu.popup_menu, popup.getMenu());
//registering popup with OnMenuItemClickListener
popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
public boolean onMenuItemClick(MenuItem item) {
Toast.makeText(
MainActivity.this,
"You Clicked : " + item.getTitle(),
Toast.LENGTH_SHORT
).show();
return true;
}
});
popup.show(); //showing popup menu
}
}); //closing the setOnClickListener method
}
}
To add programmatically:
PopupMenu menu = new PopupMenu(this, view);
menu.getMenu().add("One");
menu.getMenu().add("Two");
menu.getMenu().add("Three");
menu.show();
Follow this link for creating menu programmatically.
First delete node_modules
folder
then Restart system
Run npm install --save-dev @angular-devkit/build-angular
and
Run npm install
There is also difference in way that return results are processed (its called chaining, done
doesn't chain while then
produces call chains)
promise.then(function (x) { // Suppose promise returns "abc"
console.log(x);
return 123;
}).then(function (x){
console.log(x);
}).then(function (x){
console.log(x)
})
The following results will get logged:
abc
123
undefined
While
promise.done(function (x) { // Suppose promise returns "abc"
console.log(x);
return 123;
}).done(function (x){
console.log(x);
}).done(function (x){
console.log(x)
})
will get the following:
abc
abc
abc
---------- Update:
Btw. I forgot to mention, if you return a Promise instead of atomic type value, the outer promise will wait until inner promise resolves:
promise.then(function (x) { // Suppose promise returns "abc"
console.log(x);
return $http.get('/some/data').then(function (result) {
console.log(result); // suppose result === "xyz"
return result;
});
}).then(function (result){
console.log(result); // result === xyz
}).then(function (und){
console.log(und) // und === undefined, because of absence of return statement in above then
})
in this way it becomes very straightforward to compose parallel or sequential asynchronous operations such as:
// Parallel http requests
promise.then(function (x) { // Suppose promise returns "abc"
console.log(x);
var promise1 = $http.get('/some/data?value=xyz').then(function (result) {
console.log(result); // suppose result === "xyz"
return result;
});
var promise2 = $http.get('/some/data?value=uvm').then(function (result) {
console.log(result); // suppose result === "uvm"
return result;
});
return promise1.then(function (result1) {
return promise2.then(function (result2) {
return { result1: result1, result2: result2; }
});
});
}).then(function (result){
console.log(result); // result === { result1: 'xyz', result2: 'uvm' }
}).then(function (und){
console.log(und) // und === undefined, because of absence of return statement in above then
})
The above code issues two http requests in parallel thus making the requests complete sooner, while below those http requests are being run sequentially thus reducing server load
// Sequential http requests
promise.then(function (x) { // Suppose promise returns "abc"
console.log(x);
return $http.get('/some/data?value=xyz').then(function (result1) {
console.log(result1); // suppose result1 === "xyz"
return $http.get('/some/data?value=uvm').then(function (result2) {
console.log(result2); // suppose result2 === "uvm"
return { result1: result1, result2: result2; };
});
});
}).then(function (result){
console.log(result); // result === { result1: 'xyz', result2: 'uvm' }
}).then(function (und){
console.log(und) // und === undefined, because of absence of return statement in above then
})
Use Iterators...
var myarray = ['hello', ' hello again'];
processArray(myarray[Symbol.iterator](), () => {
console.log('all done')
})
function processArray(iter, cb) {
var curr = iter.next()
if(curr.done)
return cb()
console.log(curr.value)
processArray(iter, cb)
}

Just a shot in the dark(since you did not share the compiler
initialization code with us): the way you retrieve the compiler
causes the issue. Point your JRE to be inside the JDK as unlike jdk, jre does not provide any tools hence, results in NPE
.
As explained here http://www.postgresonline.com/journal/categories/journal/archives/339-OGR-foreign-data-wrapper-on-Windows-first-taste.html
With ogr_fdw module, its possible to open the excel sheet as foreign table in pgsql and query it directly like any other regular tables in pgsql. This is useful for reading data from the same regularly updated table
To do this, the table header in your spreadsheet must be clean, the current ogr_fdw driver can't deal with wide-width character or new lines etc. with these characters, you will probably not be able to reference the column in pgsql due to encoding issue. (Major reason I can't use this wonderful extension.)
The ogr_fdw pre-build binaries for windows are located here http://winnie.postgis.net/download/windows/pg96/buildbot/extras/ change the version number in link to download corresponding builds. extract the file to pgsql folder to overwrite the same name sub-folders. restart pgsql. Before the test drive, the module needs to be installed by executing:
CREATE EXTENSION ogr_fdw;
Usage in brief:
use ogr_fdw_info.exe to prob the excel file for sheet name list
ogr_fdw_info -s "C:/excel.xlsx"
use "ogr_fdw_info.exe -l" to prob a individual sheet and generate a table definition code.
ogr_fdw_info -s "C:/excel.xlsx" -l "sheetname"
Execute the generated definition code in pgsql, a foreign table is created and mapped to your excel file. it can be queried like regular tables.
This is especially useful, if you have many small files with the same table structure. Just change the path and name in definition, and update the definition will be enough.
This plugin supports both XLSX and XLS file. According to the document it also possible to write data back into the spreadsheet file, but all the fancy formatting in your excel will be lost, the file is recreated on write.
If the excel file is huge. This will not work. which is another reason I didn't use this extension. It load data in one time. But this extension also support ODBC interface, it should be possible to use windows' ODBC excel file driver to create a ODBC source for the excel file and use ogr_fdw or any other pgsql's ODBC foreign data wrapper to query this intermediate ODBC source. This should be fairly stable.
The downside is that you can't change file location or name easily within pgsql like in the previous approach.
A friendly reminder. The permission issue applies to this fdw extensions. since its loaded into pgsql service. pgsql must have access privileged to the excel files.
Well, lot of answers, lot of possibilities. What I am missing here is some universal method that converts a string to different C++ integral types (short, int, long, bool, ...). I came up with following solution:
#include<sstream>
#include<exception>
#include<string>
#include<type_traits>
using namespace std;
template<typename T>
T toIntegralType(const string &str) {
static_assert(is_integral<T>::value, "Integral type required.");
T ret;
stringstream ss(str);
ss >> ret;
if ( to_string(ret) != str)
throw invalid_argument("Can't convert " + str);
return ret;
}
Here are examples of usage:
string str = "123";
int x = toIntegralType<int>(str); // x = 123
str = "123a";
x = toIntegralType<int>(str); // throws exception, because "123a" is not int
str = "1";
bool y = toIntegralType<bool>(str); // y is true
str = "0";
y = toIntegralType<bool>(str); // y is false
str = "00";
y = toIntegralType<bool>(str); // throws exception
Why not just use stringstream output operator to convert a string into an integral type? Here is the answer: Let's say a string contains a value that exceeds the limit for intended integral type. For examle, on Wndows 64 max int is 2147483647. Let's assign to a string a value max int + 1: string str = "2147483648". Now, when converting the string to an int:
stringstream ss(str);
int x;
ss >> x;
x becomes 2147483647, what is definitely an error: string "2147483648" was not supposed to be converted to the int 2147483647. The provided function toIntegralType spots such errors and throws exception.
View.GONE makes the view invisible without the view taking up space in the layout. View.INVISIBLE makes the view just invisible still taking up space.
You are first using GONE and then INVISIBLE on the same view.Since, the code is executed sequentially, first the view becomes GONE then it is overridden by the INVISIBLE type still taking up space.
You should add button listener on the button and inside the onClick() method make the views visible. This should be the logic according to me in your onCreate() method.
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_setting);
final DatePicker dp2 = (DatePicker) findViewById(R.id.datePick2);
final Button btn2 = (Button) findViewById(R.id.btnDate2);
final Button btn3 = (Button) findViewById(R.id.btnVisibility);
dp2.setVisibility(View.INVISIBLE);
btn2.setVisibility(View.INVISIBLE);
bt3.setOnClickListener(new View.OnCLickListener(){
@Override
public void onClick(View view)
{
dp2.setVisibility(View.VISIBLE);
bt2.setVisibility(View.VISIBLE);
}
});
}
I think this should work easily. Hope this helps.
Here is what official hibernate docs tell us about this:
You can count the number of query results without returning them:
( (Integer) session.createQuery("select count(*) from ....").iterate().next() ).intValue()
However, it doesn't always return Integer
instance, so it is better to use java.lang.Number
for safety.
It crashed for me because one of fields in my activity id was matching with id in an other activity. I fixed it by giving a unique id.
In my loginActivity.xml password field id was "password". In my registration activity I just fixed it by giving id r_password, then it returned not null object:
password = (EditText)findViewById(R.id.r_password);
Typically we would place one of these at or near the top of the script. Scripts that parse their command lines would do the redirection after parsing.
Send stdout to a file
exec > file
with stderr
exec > file
exec 2>&1
append both stdout and stderr to file
exec >> file
exec 2>&1
As Jonathan Leffler mentioned in his comment:
exec
has two separate jobs. The first one is to replace the currently executing shell (script) with a new program. The other is changing the I/O redirections in the current shell. This is distinguished by having no argument to exec
.
By the way, you can use next code in you event handler:
switch(e.EventType)
{
case SerialData.Chars:
{
// means you receives something
break;
}
case SerialData.Eof:
{
// means receiving ended
break;
}
}
You could do it this way ..
var mystr = 'is my name.';_x000D_
mystr = mystr.replace (/^/,'John ');_x000D_
_x000D_
console.log(mystr);
_x000D_

If you need special memory alignment on the object controlled by shared_ptr, you cannot rely on make_shared, but I think it's the only one good reason about not using it.

kuboon's answer missed deleting branches which have the word master in the branch name. The following improves on his answer:
git branch -r --merged | grep -v "origin/master$" | sed 's/\s*origin\///' | xargs -n 1 git push --delete origin
Of course, it does not delete the "master" branch itself :)
This is because the className
value which you are passing as argument for
forName(String className)
method is not found or doesn't exists, or you a re passing the wrong value as the class name. Here is also a link which could help you.

Update
Module not specified
According to the snapshot you have provided this problem is because you have not determined the app module of your project, so I suggest you to choose the app module from configuration. For example:
If you have settled on a particular set of tools to access / modify your databases, I would go with whatever extension they expect you to use. This will avoid needless friction when doing development tasks.
For instance, SQLiteStudio v3.1.1 defaults to looking for files with the following extensions:
(db|sdb|sqlite|db3|s3db|sqlite3|sl3|db2|s2db|sqlite2|sl2
)
If necessary for deployment your installation mechanism could rename the file if obscuring the file type seems useful to you (as some other answers have suggested). Filename requirements for development and deployment can be different.
C# equivalent of your code is
class Imagedata : PDFStreamEngine
{
// C# uses "base" keyword whenever Java uses "super"
// so instead of super(...) in Java we should call its C# equivalent (base):
public Imagedata()
: base(ResourceLoader.loadProperties("org/apache/pdfbox/resources/PDFTextStripper.properties", true))
{ }
// Java methods are virtual by default, when C# methods aren't.
// So we should be sure that processOperator method in base class
// (that is PDFStreamEngine)
// declared as "virtual"
protected override void processOperator(PDFOperator operations, List arguments)
{
base.processOperator(operations, arguments);
}
}
In windows server 2012, even after installing asp.net you might run into this issue.
Check for "Http activation" feature. This feature is present under Web services as well.
Make sure you add the above and everything should be awesome for you !!!
Ctrl+A , Ctrl+Shift+U
should do the trick!
Edit: Ctrl+U is the shortcut to be used to convert capital letters to lowercase (reverse scenario)
I came upon this as a first-item in a Google search trying to learn to do this, and thought I would share for other folsk finding this recently the solution I found, which uses the npm package immutable.
I think its interesting to share because immutable uses the OP's EXACT situation in their own documentation - the following is not my own code but pulled from the current immutable-js documentation:
const { Seq } = require('immutable')
const myObject = { a: 1, b: 2, c: 3 }
Seq(myObject).map(x => x * x).toObject();
// { a: 1, b: 4, c: 9 }
Not that Seq has other properties ("Seq describes a lazy operation, allowing them to efficiently chain use of all the higher-order collection methods (such as map and filter) by not creating intermediate collections") and that some other immutable-js data structures might also do the job quite efficiently.
Anyone using this method will of course have to npm install immutable
and might want to read the docs:
It's probably worth mentioning that for http/https some people proxy their browser traffic through Burp/ZAP or another intercepting "attack proxy". A thread that covers options for this on Android devices can be found here: https://android.stackexchange.com/questions/32366/which-browser-does-support-proxies
Other have hit this one on the head:
main(int argc, char **argv)
give you direct access to the command line (after it has been mangled and tokenized by the shell)getopt()
and getopt_long()
but as you've seen the code to use them is a bit wordy, and quite idomatic. I generally push it out of view with something like:
typedef
struct options_struct {
int some_flag;
int other_flage;
char *use_file;
} opt_t;
/* Parses the command line and fills the options structure,
* returns non-zero on error */
int parse_options(opt_t *opts, int argc, char **argv);
Then first thing in main:
int main(int argc, char **argv){
opt_t opts;
if (parse_options(&opts,argc,argv)){
...
}
...
}
Or you could use one of the solutions suggested in Argument-parsing helpers for C/UNIX.
There is an alternative solution, use Chrome-Developer-Mode-Extension-Warning-Patcher:

Go to the project repository from the dashboard of bitbucket. Select downloads from the left menu. Choose Download repository.

You could also use numpy. When your data is stored in a numpy.ndarray:
import numpy as np
from random import sample
l = 100 #length of data
f = 50 #number of elements you need
indices = sample(range(l),f)
train_data = data[indices]
test_data = np.delete(data,indices)
You are mixing mysqli and mysql extensions, which will not work.
You need to use
$myConnection= mysqli_connect("$db_host","$db_username","$db_pass") or die ("could not connect to mysql");
mysqli_select_db($myConnection, "mrmagicadam") or die ("no database");
mysqli
has many improvements over the original mysql
extension, so it is recommended that you use mysqli
.
For a realistic approach that emulates the most human behavior, you may want to add a referer in your curl options. You may also want to add a follow_location to your curl options. Trust me, whoever said that cURLING Google results is impossible, is a complete dolt and should throw his/her computer against the wall in hopes of never returning to the internetz again. Everything that you can do "IRL" with your own browser can all be emulated using PHP cURL or libCURL in Python. You just need to do more cURLS to get buff. Then you will see what I mean. :)
$url = "http://www.google.com/search?q=".$strSearch."&hl=en&start=0&sa=N";
$ch = curl_init();
curl_setopt($ch, CURLOPT_REFERER, 'http://www.example.com/1');
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_VERBOSE, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible;)");
curl_setopt($ch, CURLOPT_URL, urlencode($url));
$response = curl_exec($ch);
curl_close($ch);

Everyone should try this jQuery plugin: xautoresize-jquery. It's really good and should solve your problem.
I feel like there is yet another point that hasn't been covered here.
Unlike the pointers, references are syntactically equivalent to the object they refer to, i.e. any operation that can be applied to an object works for a reference, and with the exact same syntax (the exception is of course the initialization).
While this may appear superficial, I believe this property is crucial for a number of C++ features, for example:
Templates. Since template parameters are duck-typed, syntactic properties of a type is all that matters, so often the same template can be used with both T
and T&
.
(or std::reference_wrapper<T>
which still relies on an implicit cast
to T&
)
Templates that cover both T&
and T&&
are even more common.
Lvalues. Consider the statement str[0] = 'X';
Without references it would only work for c-strings (char* str
). Returning the character by reference allows user-defined classes to have the same notation.
Copy constructors. Syntactically it makes sense to pass objects to copy constructors, and not pointers to objects. But there is just no way for a copy constructor to take an object by value - it would result in a recursive call to the same copy constructor. This leaves references as the only option here.
Operator overloads. With references it is possible to introduce indirection to an operator call - say, operator+(const T& a, const T& b)
while retaining the same infix notation. This also works for regular overloaded functions.
These points empower a considerable part of C++ and the standard library so this is quite a major property of references.
You have to use ':' colon instead of ';' semicolon.
As it stands now you try to execute the jar file which has not the execute bit set, hence the Permission denied.
And the variable must be CLASSPATH not classpath.
I recommend using .htaccess
. You only need to add:
DirectoryIndex home.php
or whatever page name you want to have for it.
EDIT: basic htaccess tutorial.
1) Create .htaccess
file in the directory where you want to change the index file.
.
in front, to ensure it is a "hidden" fileEnter the line above in there. There will likely be many, many other things you will add to this (AddTypes for webfonts / media files, caching for headers, gzip declaration for compression, etc.), but that one line declares your new "home" page.
2) Set server to allow reading of .htaccess
files (may only be needed on your localhost, if your hosting servce defaults to allow it as most do)
Assuming you have access, go to your server's enabled site location. I run a Debian server for development, and the default site setup is at /etc/apache2/sites-available/default
for Debian / Ubuntu. Not sure what server you run, but just search for "sites-available" and go into the "default" document. In there you will see an entry for Directory. Modify it to look like this:
<Directory /var/www/>
Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
allow from all
</Directory>
Then restart your apache server. Again, not sure about your server, but the command on Debian / Ubuntu is:
sudo service apache2 restart
Technically you only need to reload, but I restart just because I feel safer with a full refresh like that.
Once that is done, your site should be reading from your .htaccess file, and you should have a new default home page! A side note, if you have a sub-directory that runs a site (like an admin section or something) and you want to have a different "home page" for that directory, you can just plop another .htaccess
file in that sub-site's root and it will overwrite the declaration in the parent.
I have lost hours today to find the reason, fortunately this issue is not because of MapFragment implementation, fnfortunately, this does not work because nested fragments are only supported through support library from rev 11.
My implementation has an activity with actionbar (in tabbed mode) with two tabs (no viewpager), one having the map and the other having a list of entries. Of course I've been quite naive to use MapFragment inside my tab-fragments, et voila the app crashed everytime I switched back to map-tab.
( The same issue I also would have in case my tab-fragment would inflate any layout containing any other fragment ).
One option is to use the MapView (instead of MapFragment), with some overhead though ( see MapView Docs as drop-in replacement in the layout.xml, another option is to use support-library up from rev. 11 but then take programmatic approach since nested fragments are neither supported via layout. Or just working around programmatically by explicitely destroying the fragment (like in the answer from Matt / Vidar), btw: same effect is achieved using the MapView (option 1).
But actually, I did not want to loose the map everytime I tab away, that is, I wanted to keep it in memory and cleanup only upon activity close, so I decided to simply hide/show the map while tabbing, see FragmentTransaction / hide
Yes, you are synchronizing correctly. I will explain this in more detail. You must synchronize two or more method calls on the synchronizedMap object only in a case you have to rely on results of previous method call(s) in the subsequent method call in the sequence of method calls on the synchronizedMap object. Let’s take a look at this code:
synchronized (synchronizedMap) {
if (synchronizedMap.containsKey(key)) {
synchronizedMap.get(key).add(value);
}
else {
List<String> valuesList = new ArrayList<String>();
valuesList.add(value);
synchronizedMap.put(key, valuesList);
}
}
In this code
synchronizedMap.get(key).add(value);
and
synchronizedMap.put(key, valuesList);
method calls are relied on the result of the previous
synchronizedMap.containsKey(key)
method call.
If the sequence of method calls were not synchronized the result might be wrong.
For example thread 1
is executing the method addToMap()
and thread 2
is executing the method doWork()
The sequence of method calls on the synchronizedMap
object might be as follows:
Thread 1
has executed the method
synchronizedMap.containsKey(key)
and the result is "true
".
After that operating system has switched execution control to thread 2
and it has executed
synchronizedMap.remove(key)
After that execution control has been switched back to the thread 1
and it has executed for example
synchronizedMap.get(key).add(value);
believing the synchronizedMap
object contains the key
and NullPointerException
will be thrown because synchronizedMap.get(key)
will return null
.
If the sequence of method calls on the synchronizedMap
object is not dependent on the results of each other then you don't need to synchronize the sequence.
For example you don't need to synchronize this sequence:
synchronizedMap.put(key1, valuesList1);
synchronizedMap.put(key2, valuesList2);
Here
synchronizedMap.put(key2, valuesList2);
method call does not rely on the results of the previous
synchronizedMap.put(key1, valuesList1);
method call (it does not care if some thread has interfered in between the two method calls and for example has removed the key1
).
Try this - You have to import java.util.regex.*;
Pattern pattern = Pattern.compile("\\s+");
Matcher matcher = pattern.matcher(string);
boolean check = matcher.find();
String str = matcher.replaceAll(" ");
Where string
is your string on which you need to remove duplicate white spaces
Interestingly:
_dbContext.Set<T>().AddOrUpdate(entityToBeUpdatedWithId);
Or if you still is not generic:
_dbContext.Set<UserEntity>().AddOrUpdate(entityToBeUpdatedWithId);
seems to solved my problem smoothly.
It's possible to find the element in Dictionary collection by using ContainsKey or TryGetValue as follows:
class Program
{
protected static Dictionary<string, string> _tags = new Dictionary<string,string>();
static void Main(string[] args)
{
string strValue;
_tags.Add("101", "C#");
_tags.Add("102", "ASP.NET");
if (_tags.ContainsKey("101"))
{
strValue = _tags["101"];
Console.WriteLine(strValue);
}
if (_tags.TryGetValue("101", out strValue))
{
Console.WriteLine(strValue);
}
}
}
You can use relative rules:
table td + td + td + td + td {
border: none;
}
This only works if the number of columns isn't determined at runtime.
You can do something like this.
List<Map<String, Object>> mapList = jdbctemplate.queryForList(query));
return mapList.stream().collect(Collectors.toMap(k -> (Long) k.get("userid"), k -> (String) k.get("username")));
Output:
{
1: "abc",
2: "def",
3: "ghi"
}
If you want to move to another URL and clear the query parameters just use:
$location.path('/my/path').search({});

df = df.to_frame()
df = df.reset_index(level=['Name',"TIME"])

INTRO: This answer was written in a time when Numpy was version 1.11 and behaviour of NAT comparison was supposed to change since version 1.12. Clearly that wasn't the case and the second part of answer became wrong. The first part of answer may be not applicable for new versions of numpy. Be sure you've checked MSeifert's answers below.
import numpy as np
nat = np.datetime64('NaT')
def nat_check(nat):
return nat == np.datetime64('NaT')
nat_check(nat)
Out[4]: FutureWarning: In the future, 'NAT == x' and 'x == NAT' will always be False.
True
nat_check(nat)
Out[5]: True
If you want to suppress the warning you can use the catch_warnings context manager:
import numpy as np
import warnings
nat = np.datetime64('NaT')
def nat_check(nat):
with warnings.catch_warnings():
warnings.simplefilter("ignore")
return nat == np.datetime64('NaT')
nat_check(nat)
Out[5]: True
And finally you might check numpy version to handle changed behavior since version 1.12.0:
def nat_check(nat):
if [int(x) for x in np.__version__.split('.')[:-1]] > [1, 11]:
return nat != nat
with warnings.catch_warnings():
warnings.simplefilter("ignore")
return nat == np.datetime64('NaT')

A solution to ensure that images don't get cut when printed in a Web page is to have the following CSS rule:
@media print {

max-width:100% !important;
}
}
import csv
with open("source","rb") as source:
rdr= csv.reader( source )
with open("result","wb") as result:
wtr= csv.writer( result )
for r in rdr:
wtr.writerow( (r[0], r[1], r[3], r[4]) )
BTW, the for
loop can be removed, but not really simplified.
in_iter= ( (r[0], r[1], r[3], r[4]) for r in rdr )
wtr.writerows( in_iter )
Also, you can stick in a hyper-literal way to the requirements to delete a column. I find this to be a bad policy in general because it doesn't apply to removing more than one column. When you try to remove the second, you discover that the positions have all shifted and the resulting row isn't obvious. But for one column only, this works.
del r[2]
wtr.writerow( r )
Well in pure javascript my thinking is that you would first have to collate them inside a collection.
var divs = document.getElementsByTagName("div");
//divs now contain each and every div element on the page
var selectionDiv = document.getElementById("MySecondDiv");
So basically with selectionDiv iterate through the collection to find its index, and then obviously -1 = previous +1 = next within bounds
for(var i = 0; i < divs.length;i++)
{
if(divs[i] == selectionDiv)
{
var previous = divs[i - 1];
var next = divs[i + 1];
}
}
Please be aware though as I say that extra logic would be required to check that you are within the bounds i.e. you are not at the end or start of the collection.
This also will mean that say you have a div which has a child div nested. The next div would not be a sibling but a child, So if you only want siblings on the same level as the target div then definately use nextSibling checking the tagName property.
Just to elaborate a bit on the meta-tag thing. I've heard a talk, where a statement was made, one should always insert the "no-sniff" meta tag in the html to prevent browser sniffing (just like OP did):
<meta content="text/html; charset=UTF-8; X-Content-Type-Options=nosniff" http-equiv="Content-Type" />
However, this is not a valid method for w3c compliant websites, the validator will raise an error:
Bad value text/html; charset=UTF-8; X-Content-Type-Options=nosniff for attribute content on element meta: The legacy encoding contained ;, which is not a valid character in an encoding name.
And there is no fixing this. To rightly turn off no-sniff, one has to go to the server settings and turn it off there. Because the "no-sniff" option is something from the HTTP header, not from the HTML file which is attached at the HTTP response.
To check if the no-sniff option is disabled, one can enable the developer console, networks tab and then inspect the HTTP response header:
From python 3.6 on you can also use Literal String Interpolation, "f-strings". In your particular case the solution would be:
if re.search(rf"\b(?=\w){TEXTO}\b(?!\w)", subject, re.IGNORECASE):
...do something
EDIT:
Since there have been some questions in the comment on how to deal with special characters I'd like to extend my answer:
raw strings ('r'):
One of the main concepts you have to understand when dealing with special characters in regular expressions is to distinguish between string literals and the regular expression itself. It is very well explained here:
In short:
Let's say instead of finding a word boundary \b
after TEXTO
you want to match the string \boundary
. The you have to write:
TEXTO = "Var"
subject = r"Var\boundary"
if re.search(rf"\b(?=\w){TEXTO}\\boundary(?!\w)", subject, re.IGNORECASE):
print("match")
This only works because we are using a raw-string (the regex is preceded by 'r'), otherwise we must write "\\\\boundary" in the regex (four backslashes). Additionally, without '\r', \b' would not converted to a word boundary anymore but to a backspace!
re.escape:
Basically puts a backspace in front of any special character. Hence, if you expect a special character in TEXTO, you need to write:
if re.search(rf"\b(?=\w){re.escape(TEXTO)}\b(?!\w)", subject, re.IGNORECASE):
print("match")
NOTE: For any version >= python 3.7: !
, "
, %
, '
, ,
, /
, :
, ;
, <
, =
, >
, @
, and `
are not escaped. Only special characters with meaning in a regex are still escaped. _
is not escaped since Python 3.3.(s. here)
Curly braces:
If you want to use quantifiers within the regular expression using f-strings, you have to use double curly braces. Let's say you want to match TEXTO followed by exactly 2 digits:
if re.search(rf"\b(?=\w){re.escape(TEXTO)}\d{{2}}\b(?!\w)", subject, re.IGNORECASE):
print("match")
This problem happens because you are calling fun.cpp
instead of fun.hpp
. So c++ compiler finds func.cpp definition twice and throws this error.
Change line 3 of your main.cpp
file, from #include "fun.cpp"
to #include "fun.hpp"
.
I can't speak to what you are trying to do specifically with the function itself, but if you don't like the regex being built every time, here are two solutions and some caveats about each.
Here is one way to do this:
function makeSortString(s) {
if(!makeSortString.translate_re) makeSortString.translate_re = /[öäüÖÄÜ]/g;
var translate = {
"ä": "a", "ö": "o", "ü": "u",
"Ä": "A", "Ö": "O", "Ü": "U" // probably more to come
};
return ( s.replace(makeSortString.translate_re, function(match) {
return translate[match];
}) );
}
This will obviously make the regex a property of the function itself. The only thing you may not like about this (or you may, I guess it depends) is that the regex can now be modified outside of the function's body. So, someone could do this to modify the interally-used regex:
makeSortString.translate_re = /[a-z]/g;
So, there is that option.
One way to get a closure, and thus prevent someone from modifying the regex, would be to define this as an anonymous function assignment like this:
var makeSortString = (function() {
var translate_re = /[öäüÖÄÜ]/g;
return function(s) {
var translate = {
"ä": "a", "ö": "o", "ü": "u",
"Ä": "A", "Ö": "O", "Ü": "U" // probably more to come
};
return ( s.replace(translate_re, function(match) {
return translate[match];
}) );
}
})();
Hopefully this is useful to you.
UPDATE: It's early and I don't know why I didn't see the obvious before, but it might also be useful to put you translate
object in a closure as well:
var makeSortString = (function() {
var translate_re = /[öäüÖÄÜ]/g;
var translate = {
"ä": "a", "ö": "o", "ü": "u",
"Ä": "A", "Ö": "O", "Ü": "U" // probably more to come
};
return function(s) {
return ( s.replace(translate_re, function(match) {
return translate[match];
}) );
}
})();

I found a combination of these answers gave me the best outcome - allowing me to still position the tooltip and attach it to the relevant container:
$('body').on('mouseenter', '[rel=tooltip]', function(){
var el = $(this);
if (el.data('tooltip') === undefined) {
el.tooltip({
placement: el.data("placement") || "top",
container: el.data("container") || false
});
}
el.tooltip('show');
});
$('body').on('mouseleave', '[rel=tooltip]', function(){
$(this).tooltip('hide');
});
Relevant HTML:
<button rel="tooltip" class="btn" data-placement="bottom" data-container=".some-parent" title="Show Tooltip">
<i class="icon-some-icon"></i>
</button>
You can use pandas methods where
and mask
:
df['color'] = 'green'
df['color'] = df['color'].where(df['Set']=='Z', other='red')
# Replace values where the condition is False
or
df['color'] = 'red'
df['color'] = df['color'].mask(df['Set']=='Z', other='green')
# Replace values where the condition is True
Output:
Type Set color
1 A Z green
2 B Z green
3 B X red
4 C Y red
Python integers don't have an inherent length or number of significant digits. If you want them to print a specific way, you need to convert them to a string. There are several ways you can do so that let you specify things like padding characters and minimum lengths.
To pad with zeros to a minimum of three characters, try:
length = 1
print(format(length, '03'))
As far as I can see in the manual, it is not possible to call functions inside HEREDOC strings. A cumbersome way would be to prepare the words beforehand:
<?php
$world = _("World");
$str = <<<EOF
<p>Hello</p>
<p>$world</p>
EOF;
echo $str;
?>
a workaround idea that comes to mind is building a class with a magic getter method.
You would declare a class like this:
class Translator
{
public function __get($name) {
return _($name); // Does the gettext lookup
}
}
Initialize an object of the class at some point:
$translate = new Translator();
You can then use the following syntax to do a gettext lookup inside a HEREDOC block:
$str = <<<EOF
<p>Hello</p>
<p>{$translate->World}</p>
EOF;
echo $str;
?>
$translate->World
will automatically be translated to the gettext lookup thanks to the magic getter method.
To use this method for words with spaces or special characters (e.g. a gettext entry named Hello World!!!!!!
, you will have to use the following notation:
$translate->{"Hello World!!!!!!"}
This is all untested but should work.
Update: As @mario found out, it is possible to call functions from HEREDOC strings after all. I think using getters like this is a sleek solution, but using a direct function call may be easier. See the comments on how to do this.

Look at the open function in Perl - especially the variants using a '|' (pipe) in the arguments. Done correctly, you'll get a file handle that you can use to read the output of the command. The back tick operators also do this.
You might also want to review whether Perl has access to the C functions that the command itself uses. For example, for ls -a
, you could use the opendir function, and then read the file names with the readdir function, and finally close the directory with (surprise) the closedir function. This has a number of benefits - precision probably being more important than speed. Using these functions, you can get the correct data even if the file names contain odd characters like newline.
Since placeholder disappear on input, you can use:
input:placeholder-shown{
//rules for not empty input
}
