If you want lots of networks then you can control how much IP space docker hands out to each network via the default-address-pools
deamon setting, so you could add this to your /etc/docker/daemon.json
:
{
"bip": "10.254.1.1/24",
"default-address-pools":[{"base":"10.254.0.0/16","size":28}],
}
Here I've reserved 10.254.1.1/24
(254 IP addresses) for the bridge network.
For any other network I create, docker will partition up the 10.254.0.0
space (65k hosts), giving out 16 hosts at a time ("size":28
refers to the CIDR mask, for 16 hosts).
If I create a few networks and then run docker network inspect <name>
on them, it might display something like this:
...
"Subnet": "10.254.0.32/28",
"Gateway": "10.254.0.33"
...
The 10.254.0.32/28
means this network can use 16 ip addresses from 10.254.0.32
- 10.254.0.47
.
C++ programs are translated to assembly programs during the generation of machine code from the source code. It would be virtually wrong to say assembly is slower than C++. Moreover, the binary code generated differs from compiler to compiler. So a smart C++ compiler may produce binary code more optimal and efficient than a dumb assembler's code.
However I believe your profiling methodology has certain flaws. The following are general guidelines for profiling:
click on button and open Image gallery and set image in imageview swift 3.0
add three delegate UIImagePickerControllerDelegate,UIPopoverControllerDelegate,UINavigationControllerDelegate
var picker:UIImagePickerController?=UIImagePickerController()
@IBOutlet var imgPhoto: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
picker?.delegate=self
}
@IBAction func btnAddPhotoClicked(_ sender: UIButton) {
openGallary()
}
func openGallary()
{
picker!.allowsEditing = false
picker!.sourceType = UIImagePickerControllerSourceType.photoLibrary
present(picker!, animated: true, completion: nil)
}
//MARK:- ImagePicker Controller Delegate
//MARK:-
func imagePickerControllerDidCancel(_ picker:
UIImagePickerController) {
dismiss(animated: true, completion: nil)
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
if let chosenImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
imgPhoto.contentMode = .scaleToFill
imgPhoto.image = chosenImage
} else{
print("Something went wrong")
}
self.dismiss(animated: true, completion: nil)
}

It's as the error message says "The value violated the integrity constraints for the column" for column "Copy of F2"
Make it so it doesn't violate the value in the target table. What the allowable values are, data types, etc are not provided in your question so we cannot be more specific in answering.
To address the downvote, No, really it's as it says: you are putting something into a column that is not allowed. It could be Faizan points out, that you're putting a NULL into a NOT NULLable column, but it could be a whole host of other things and as the original poster never provided any update, we're left to guess. Was there a foreign key constraint that the insert violated? Maybe there's a check constraint that got blown? Maybe the source column in Excel has a valid date value for Excel that is not valid for the target column's date/time data type.
Thus, baring concrete information, the best possible answer is "don't do the thing that breaks it" In this case, something about "Copy of F2" is bad for the target column. Give us table definitions, supplied values, etc, then you can specific answers.
Telling people to make a NOT NULLable column into a NULLable one might be the right answer. It might also be the most horrific answer known to mankind. If an existing process expects there to always be a value in column "Copy of F2" changing the constraint to NULL can wreak havoc on existing queries. For example
SELECT * FROM ArbitraryTable AS T WHERE T.[Copy of F2] = '';
Currently, that query retrieves everything that was freshly imported because Copy of F2
is a poorly named status indicator. That data needs to get fed into the next system so... bills can get paid. As soon as you make it such that unprocessed rows can have a NULL value, the above query no longer satisfies that. Bills don't get paid, collections repos your building and now you're out of a job, all because you didn't do impact analysis, etc, etc.

I think you should make a subquery to do grouping. In this case inner subquery returns few rows and you don't need a CASE statement. So I think this is going to be faster:
select Detail.ReceiptDate AS 'DATE',
SUM(TotalMailed),
SUM(TotalReturnMail),
SUM(TraceReturnedMail)
from
(
select SentDate AS 'ReceiptDate',
count('TotalMailed') AS TotalMailed,
0 as TotalReturnMail,
0 as TraceReturnedMail
from MailDataExtract
where sentdate is not null
GROUP BY SentDate
UNION ALL
select MDE.ReturnMailDate AS 'ReceiptDate',
0 AS TotalMailed,
count(TotalReturnMail) as TotalReturnMail,
0 as TraceReturnedMail
from MailDataExtract MDE
where MDE.ReturnMailDate is not null
GROUP BY MDE.ReturnMailDate
UNION ALL
select MDE.ReturnMailDate AS 'ReceiptDate',
0 AS TotalMailed,
0 as TotalReturnMail,
count(TraceReturnedMail) as TraceReturnedMail
from MailDataExtract MDE
inner join DTSharedData.dbo.ScanData SD
ON SD.ScanDataID = MDE.ReturnScanDataID
where MDE.ReturnMailDate is not null AND SD.ReturnMailTypeID = 1
GROUP BY MDE.ReturnMailDate
) as Detail
GROUP BY Detail.ReceiptDate

In my case it was because I didn't connect to databases yet when first opened solution. click connection manager tab, establish connection to every datasource in that tab, run project
When you first set up this package, I am guessing that either a one or two digit number was the first value in the ShipTo column. Your package reading from the Excel picked a numeric type for that input field and the word "ALL" fails the package since the input spec for that field is numeric. There are several ways to fix this beforehand, but to fix it after the fact, the easiest way is to right click the Excel Source and choose Show Advanced Editor... From there, choose the tab that says Input and Output Properties. In the topmost part of the inputs and outputs section of that dialog box, find the column ShipTo. You will have to drill down to find it. Set the DataType to "string [DT_STR]" and the length to 20.
Click OK then attempt to run your package again.
Strongly typed var don't seem to be available, I have to do the following in order to get access to them:

I have changed all jars of spring version in lib folder of WEB INF, it works for me if u are using maven project just update dependency with different version it might work
Add
"aaSorting": []
And check if default value is not null
only set sortable column then
if ($('#table').DataTable().order().length == 1) {
d.SortColumn = $('#table').DataTable().order()[0][0];
d.SortOrder = $('#table').DataTable().order()[0][1];
}
Read here
$('#example').dataTable({
"aoColumns": [
null,
null,
{ "bSortable": false }, // <-- disable sorting for column 3
null
]
});
http://datatables.net/usage/columns under bSortable
You can specify which columns to disable using aoColumnDefs
and aTargets
$('#example').dataTable({
"aoColumnDefs": [
{
"bSortable": false,
"aTargets": [ -1 ] // <-- gets last column and turns off sorting
}
]
});
This seems to also happen when you use the new SSIS 2012 "Shared Connection Manager" concept where the connection managers are not defined within your package but the Visual Studio project and just get referenced in the package. Executing it via SQL Agent or DTEXEC yields the same error message.
I haven't found a solution for that yet but would love to get some feedback if anybody experienced it before.
Make sure you have installed 'make' tool through Cygwin's installer.

SELECT DATEDIFF(s, '1970-01-01 00:00:00', GETUTCDATE())
My bad, SELECT unix_timestamp(time) Time format: YYYY-MM-DD HH:MM:SS or YYMMDD or YYYYMMDD. More on using timestamps with MySQL:

You can use the format
method of the DateTime
class:
$date = new DateTime('2000-01-01');
$result = $date->format('Y-m-d H:i:s');
If format
fails for some reason, it will return FALSE
. In some applications, it might make sense to handle the failing case:
if ($result) {
echo $result;
} else { // format failed
echo "Unknown Time";
}
This error is caused because your charset is wrong.
Set charset after open tag:
header('Content-Type: text/html; charset=utf-8');
And set charset utf8 in your database :
mysql_query("SET NAMES 'utf8'");
Modern answer: use java.time, the modern Java date and time API, for your date and time work. Back in 2011 it was right to use the Timestamp
class, but since JDBC 4.2 it is no longer advised.
For your work we need a time zone and a couple of formatters. We may as well declare them static:
static ZoneId zone = ZoneId.of("America/Marigot");
static DateTimeFormatter dateFormatter = DateTimeFormatter.ofPattern("MM/dd/uuuu");
static DateTimeFormatter timeFormatter = DateTimeFormatter.ofPattern("HH:mm xx");
Now the code could be for example:
while(resultSet.next()) {
ZonedDateTime dtStart = resultSet.getObject("dtStart", OffsetDateTime.class)
.atZoneSameInstant(zone);
// I would like to then have the date and time
// converted into the formats mentioned...
String dateFormatted = dtStart.format(dateFormatter);
String timeFormatted = dtStart.format(timeFormatter);
System.out.format("Date: %s; time: %s%n", dateFormatted, timeFormatted);
}
Example output (using the time your question was asked):
Date: 09/20/2011; time: 18:13 -0400
In your database timestamp with time zone
is recommended for timestamps. If this is what you’ve got, retrieve an OffsetDateTime
as I am doing in the code. I am also converting the retrieved value to the user’s time zone before formatting date and time separately. As time zone I supplied America/Marigot as an example, please supply your own. You may also leave out the time zone conversion if you don’t want any, of course.
If the datatype in SQL is a mere timestamp
without time zone, retrieve a LocalDateTime
instead. For example:
ZonedDateTime dtStart = resultSet.getObject("dtStart", LocalDateTime.class)
.atZone(zone);
No matter the details I trust you to do similarly for dtEnd
.
I wasn’t sure what you meant by the xx
in HH:MM xx
. I just left it in the format pattern string, which yields the UTC offset in hours and minutes without colon.
Link: Oracle tutorial: Date Time explaining how to use java.time.
I was ultimately able to resolve the solution by setting the column type in the flat file connection to be of type "database date [DT_DBDATE]"
Apparently the differences between these date formats are as follow:
DT_DATE A date structure that consists of year, month, day, and hour.
DT_DBDATE A date structure that consists of year, month, and day.
DT_DBTIMESTAMP A timestamp structure that consists of year, month, hour, minute, second, and fraction
By changing the column type to DT_DBDATE the issue was resolved - I attached a Data Viewer and the CYCLE_DATE value was now simply "12/20/2010" without a time component, which apparently resolved the issue.
I finally found the problem. The error was not the good one.
Apparently, Ole DB source have a bug that might make it crash and throw that error. I replaced the OLE DB destination with a OLE DB Command with the insert statement in it and it fixed it.

$('#id').attr('onclick', 'function()');
Right now (11 Jul 2015) this solution is still working (jquery 2.1.4); in my opinion, it is the best one to pick up.
I have build such kind of application using approximatively the same approach except :
UIImage
but instead draw the image in the layer when zooming is 1. Those tiles will be released automatically when memory warnings are issued.Whenever the user start zooming, I acquire the CGPDFPage
and render it using the appropriate CTM. The code in - (void)drawLayer: (CALayer*)layer inContext: (CGContextRef) context
is like :
CGAffineTransform currentCTM = CGContextGetCTM(context);
if (currentCTM.a == 1.0 && baseImage) {
//Calculate ideal scale
CGFloat scaleForWidth = baseImage.size.width/self.bounds.size.width;
CGFloat scaleForHeight = baseImage.size.height/self.bounds.size.height;
CGFloat imageScaleFactor = MAX(scaleForWidth, scaleForHeight);
CGSize imageSize = CGSizeMake(baseImage.size.width/imageScaleFactor, baseImage.size.height/imageScaleFactor);
CGRect imageRect = CGRectMake((self.bounds.size.width-imageSize.width)/2, (self.bounds.size.height-imageSize.height)/2, imageSize.width, imageSize.height);
CGContextDrawImage(context, imageRect, [baseImage CGImage]);
} else {
@synchronized(issue) {
CGPDFPageRef pdfPage = CGPDFDocumentGetPage(issue.pdfDoc, pageIndex+1);
pdfToPageTransform = CGPDFPageGetDrawingTransform(pdfPage, kCGPDFMediaBox, layer.bounds, 0, true);
CGContextConcatCTM(context, pdfToPageTransform);
CGContextDrawPDFPage(context, pdfPage);
}
}
issue is the object containg the CGPDFDocumentRef
. I synchronize the part where I access the pdfDoc
property because I release it and recreate it when receiving memoryWarnings. It seems that the CGPDFDocumentRef
object do some internal caching that I did not find how to get rid of.
It is important to highlight that the Property (MaximumErrorCount) that needs to be changed must be set as more than 0 (which is the default) in the Package level and not in the specific control that is showing the error (I tried this and it does not work!)
Be sure that in the Properties Window, the Pull down menu is set to "Package", then look for the property MaximumErrorCount to change it.
1.84E-07 is the exact value, represented using scientific notation, also known as exponential notation.
1.845E-07 is the same as 0.0000001845. Excel will display a number very close to 0 as 0, unless you modify the formatting of the cell to display more decimals.
C# however will get the actual value from the cell. The ToString method use the e-notation when converting small numbers to a string.
You can specify a format string if you don't want to use the e-notation.
you can do this work with Regular Expressions.
string input = "dtststx";
char searching_char = 't';
int output = Regex.Matches(input, "["+ searching_char +"]")[2].Index;
best regard.
why do these two different operators, [ ]
, and [[ ]]
, return the same result?
x = list(1, 2, 3, 4)
[ ]
provides sub setting operation. In general sub set of any object
will have the same type as the original object. Therefore, x[1]
provides a list. Similarly x[1:2]
is a subset of original list,
therefore it is a list. Ex.
x[1:2]
[[1]] [1] 1
[[2]] [1] 2
[[ ]]
is for extracting an element from the list. x[[1]]
is valid
and extract the first element from the list. x[[1:2]]
is not valid as [[ ]]
does not provide sub setting like [ ]
.
x[[2]] [1] 2
> x[[2:3]] Error in x[[2:3]] : subscript out of bounds
Additional answer for Visual Studio 2012:
You can open .dtsx along with their corresponding .dtproj project files with the SQL Server Data Tools Business Intelligence (SSDT-BI) add-in:
http://www.microsoft.com/download/details.aspx?id=36843
If the projects were created with an earlier version they will require an upgrade.
I did have some hang ups installing this - the install would spin on "Install_VSTA2012_CPU32_Action" and similar steps. It wasn't until I did a repair inside of the same installer did it install completely.
The problem of converting from any non-unicode source to a unicode SQL Server table can be solved by:
Here is a simpler option that works when I encounter this.
After you create the connection, select the connection and open the Properties. In the Expressions category find Password. Re-enter the password and hit Enter. It will now be saved to the connection.
I found this question in looking for my own solution to a very complex join. This is an alternative solution, to a more complex version of the problem, which I thought might be useful.
I needed to populate the product_id field in the activities table, where activities are numbered in a unit, and units are numbered in a level (identified using a string ??N), such that one can identify activities using an SKU ie L1U1A1. Those SKUs are then stored in a different table.
I identified the following to get a list of activity_id vs product_id:-
SELECT a.activity_id, w.product_id
FROM activities a
JOIN units USING(unit_id)
JOIN product_types USING(product_type_id)
JOIN web_products w
ON sku=CONCAT('L',SUBSTR(product_type_code,3), 'U',unit_index, 'A',activity_index)
I found that that was too complex to incorporate into a SELECT within mysql, so I created a temporary table, and joined that with the update statement:-
CREATE TEMPORARY TABLE activity_product_ids AS (<the above select statement>);
UPDATE activities a
JOIN activity_product_ids b
ON a.activity_id=b.activity_id
SET a.product_id=b.product_id;
I hope someone finds this useful
I had similar issue just that excel was the destination in my case instead of source as in the case of the original question/issue. I have spent hours to resolve this issue but looks like finally Soniya Parmar saved the day for me. I have set job and let it run for few iterations already and all is good now. As per her suggestion I set up the delay validation of the Excel connection manager to 'True. Thanks Soniya

I've used the following recipe:
and it worked for me...
You're obviously not disposing of things.
Consider the "using" command when temporarily using objects that implement IDisposable.
This uses a regular expression, and it works as well:
var date = new Date(parseInt(/^\/Date\((.*?)\)\/$/.exec(jsonDate)[1], 10));
In my case, the problem was setting the variable of the Execute SQL Task, in parameters mapping the parameter name, (in OLEDB must be the position of the parameter that you call in the stored procedure), I had 1, but the first parameter starts in 0, so I changed it and voilá!

I encountered this problem because the dataset was filtered wrongly and the resultant data frame was empty. Even the following caused the error to show:

Regex is not on the list of search features, and it was on (more or less, as Better message search functionality (i.e. Wildcard and partial word search)) the list of pre-canned feature requests, so the answer is "you cannot do this via the Gmail web UI" :-(
There are no current Labs features which offer this. SIEVE filters would be another way to do this, that too was not supported, there seems to no longer be any definitive statement on SIEVE support in the Gmail help.
Updated for link rot The pre-canned list of feature requests was, er canned, the original is on archive.org dated 2012, now you just get redirected to a dumbed down page telling you how to give feedback. Lack of SIEVE support was covered in answer 78761 Does Gmail support all IMAP features?, since some time in 2015 that answer silently redirects to the answer about IMAP client configuration, archive.org has a copy dated 2014.
With the current search facility brackets of any form () {} []
are used for grouping, they have no observable effect if there's just one term within. Using (aaa|bbb)
and [aaa|bbb]
are equivalent and will both find words aaa
or bbb
. Most other punctuation characters, including \
, are treated as a space or a word-separator, +
-
:
and "
do have special meaning though, see the help.
As of 2016, only the form "{term1 term2}
" is documented for this, and is equivalent to the search "term1 OR term2
".
You can do regex searches on your mailbox (within limits) programmatically via Google docs: http://www.labnol.org/internet/advanced-gmail-search/21623/ has source showing how it can be done (copy the document, then Tools > Script Editor
to get the complete source).
You could also do this via IMAP as described here: Python IMAP search for partial subject and script something to move messages to different folder. The IMAP SEARCH verb only supports substrings, not regex (Gmail search is further limited to complete words, not substrings), further processing of the matches to apply a regex would be needed.
For completeness, one last workaround is: Gmail supports plus addressing, if you can change the destination address to [email protected]
it will still be sent to your mailbox where you can filter by recipient address. Make sure to filter using the full email address to:[email protected]
. This is of course more or less the same thing as setting up a dedicated Gmail address for this purpose :-)

There are lot of different Timers in the .NET BCL:
When to use which?
System.Timers.Timer
, which fires an event and executes the code in one or more event sinks at regular intervals. The class is intended for use as a server-based or service component in a multithreaded environment; it has no user interface and is not visible at runtime.System.Threading.Timer
, which executes a single callback method on a thread pool thread at regular intervals. The callback method is defined when the timer is instantiated and cannot be changed. Like the System.Timers.Timer class, this class is intended for use as a server-based or service component in a multithreaded environment; it has no user interface and is not visible at runtime.System.Windows.Forms.Timer
(.NET Framework only), a Windows Forms component that fires an event and executes the code in one or more event sinks at regular intervals. The component has no user interface and is designed for use in a single-threaded environment; it executes on the UI thread.System.Web.UI.Timer
(.NET Framework only), an ASP.NET component that performs asynchronous or synchronous web page postbacks at a regular interval.System.Windows.Threading.DispatcherTimer
, a timer that's integrated into the Dispatcher queue. This timer is processed with a specified priority at a specified time interval.Some of them needs explicit Start
call to begin ticking (for example System.Timers
, System.Windows.Forms
). And an explicit Stop
to finish ticking.
using TimersTimer = System.Timers.Timer;
static void Main(string[] args)
{
var timer = new TimersTimer(1000);
timer.Elapsed += (s, e) => Console.WriteLine("Beep");
Thread.Sleep(1000); //1 second delay
timer.Start();
Console.ReadLine();
timer.Stop();
}
While on the other hand there are some Timers (like: System.Threading
) where you don't need explicit Start
and Stop
calls. (The provided delegate will run a background thread.) Your timer will tick until you or the runtime dispose it.
So, the following two versions will work in the same way:
using ThreadingTimer = System.Threading.Timer;
static void Main(string[] args)
{
var timer = new ThreadingTimer(_ => Console.WriteLine("Beep"), null, TimeSpan.FromSeconds(1), TimeSpan.FromSeconds(1));
Console.ReadLine();
}
using ThreadingTimer = System.Threading.Timer;
static void Main(string[] args)
{
StartTimer();
Console.ReadLine();
}
static void StartTimer()
{
var timer = new ThreadingTimer(_ => Console.WriteLine("Beep"), null, TimeSpan.FromSeconds(1), TimeSpan.FromSeconds(1));
}
But if your timer
disposed then it will stop ticking obviously.
using ThreadingTimer = System.Threading.Timer;
static void Main(string[] args)
{
StartTimer();
GC.Collect(0);
Console.ReadLine();
}
static void StartTimer()
{
var timer = new ThreadingTimer(_ => Console.WriteLine("Beep"), null, TimeSpan.FromSeconds(1), TimeSpan.FromSeconds(1));
}
LENGTH()
returns the length of the string measured in bytes.
CHAR_LENGTH()
returns the length of the string measured in characters.
This is especially relevant for Unicode, in which most characters are encoded in two bytes. Or UTF-8, where the number of bytes varies. For example:
select length(_utf8 '€'), char_length(_utf8 '€')
--> 3, 1
As you can see the Euro sign occupies 3 bytes (it's encoded as 0xE282AC
in UTF-8) even though it's only one character.
easy:
location.href.replace(/^http/, 'ws') + '/to/ws'
// or if you hate regexp:
location.href.replace('http://', 'ws://').replace('https://', 'wss://') + '/to/ws'
Use subset within ggplot
ggplot(data = subset(df, ID == "P1" | ID == "P2") +
aes(Value1, Value2, group=ID, colour=ID) +
geom_line()
Building on @miklov-kriven's very helpful answer, I hope these two additional points of consideration prove helpful to someone:
(1) I find it a nice idea to include serializer and de-serializer as static inner classes in the same class. NB, using ThreadLocal for thread safety of SimpleDateFormat.
public class DateConverter {
private static final ThreadLocal<SimpleDateFormat> sdf =
ThreadLocal.<SimpleDateFormat>withInitial(
() -> {return new SimpleDateFormat("yyyy-MM-dd HH:mm a z");});
public static class Serialize extends JsonSerializer<Date> {
@Override
public void serialize(Date value, JsonGenerator jgen SerializerProvider provider) throws Exception {
if (value == null) {
jgen.writeNull();
}
else {
jgen.writeString(sdf.get().format(value));
}
}
}
public static class Deserialize extends JsonDeserializer<Date> {
@Overrride
public Date deserialize(JsonParser jp, DeserializationContext ctxt) throws Exception {
String dateAsString = jp.getText();
try {
if (Strings.isNullOrEmpty(dateAsString)) {
return null;
}
else {
return new Date(sdf.get().parse(dateAsString).getTime());
}
}
catch (ParseException pe) {
throw new RuntimeException(pe);
}
}
}
}
(2) As an alternative to using @JsonSerialize and @JsonDeserialize annotations on each individual class member you could also consider overriding Jackson's default serialization by applying the custom serialization at an application level, that is all class members of type Date will be serialized by Jackson using this custom serialization without explicit annotation on each field. If you are using Spring Boot for example one way to do this would as follows:
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
@Bean
public Module customModule() {
SimpleModule module = new SimpleModule();
module.addSerializer(Date.class, new DateConverter.Serialize());
module.addDeserializer(Date.class, new Dateconverter.Deserialize());
return module;
}
}
I was able archive it using this.
<input type="text" onkeydown="javascript: return event.keyCode === 8 || event.keyCode === 46 ? true : !isNaN(Number(event.key))" maxlength="4">
One way is to use the version of parse that takes an InputSource rather than a file
A SAX InputSource can be constructed from a Reader object. One Reader object is the StringReader
So something like
parse(new InputSource(new StringReader(myString))) may work.
I am a little late but for Python 3.9.1 this worked for me and removed the -b prefix:
print(outputCode.decode())
Unfortunately, re.escape()
is not suited for the replacement string:
>>> re.sub('a', re.escape('_'), 'aa')
'\\_\\_'
A solution is to put the replacement in a lambda:
>>> re.sub('a', lambda _: '_', 'aa')
'__'
because the return value of the lambda is treated by re.sub()
as a literal string.
If you want to retrieve the item selected from listbox, here is the code...
String SelectedItem = listBox1.SelectedItem.Value;
You could use the event window.oncontextmenu
, for example:
window.oncontextmenu = function () {_x000D_
alert('Right Click')_x000D_
}
_x000D_
<h1>Please Right Click here!</h1>
_x000D_
For Windows Users :
If this issue occurs on your self hosted server (eg: your custom CDN) and the browser (Chrome) says something like ... ('text/plain') is not executable ...
when trying to load your javascript file ...
Here is what you need to do :
Win + R > regedit
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.js
application/javascript
or not application/javascript
and try again I found two ways to handle this. Choose the best for your case. Solutions tested on Firefox 53 and Safari 10.1
1. Detect if user is using the back/foreward button, then reload whole page
if (!!window.performance && window.performance.navigation.type === 2) {
// value 2 means "The page was accessed by navigating into the history"
console.log('Reloading');
window.location.reload(); // reload whole page
}
2. reload whole page if page is cached
window.onpageshow = function (event) {
if (event.persisted) {
window.location.reload();
}
};
Sometimes you need to use full URL with ssh://
scheme:
ssh://git@yourhost:port/path/repo.git
or with specified port:
ssh://git@yourhost:port/path/repo.git
For me it solved the problem.
Not a for each exactly, but you can do nested SQL
SELECT
distinct a.ID,
a.col2,
(SELECT
SUM(b.size)
FROM
tableb b
WHERE
b.id = a.col3)
FROM
tablea a
Pretty subjective but my take:
Architecture The overall design of the system including interactions with other systems, hardware requirement, overall component design, and data flow.
Design The organization and flow of a component in the overall system. This would also include the component's API for interaction with other components.
I have tried to give the 777
access to storage folder and it have work for me
1) go to your laravel root directory , (/var/www/html
for me) and run the following command
chmod 777 -R storage
I think you hit the same issue as discussed in this post. You forgot to escape your \
character.
You can also use
android:layout_gravity="bottom"
for your textview
A good seed initialisation can be done like this
Random rnd = new Random((int)DateTime.Now.Ticks);
The ticks will be unique and the cast into a int with probably a loose of value will be OK.
Cleaned up @Wazime solution a little. Works great as a general solution.
$(document).on('shown.bs.dropdown', '.table-responsive', function (e) {
// The .dropdown container
var $container = $(e.target);
// Find the actual .dropdown-menu
var $dropdown = $container.find('.dropdown-menu');
if ($dropdown.length) {
// Save a reference to it, so we can find it after we've attached it to the body
$container.data('dropdown-menu', $dropdown);
} else {
$dropdown = $container.data('dropdown-menu');
}
$dropdown.css('top', ($container.offset().top + $container.outerHeight()) + 'px');
$dropdown.css('left', $container.offset().left + 'px');
$dropdown.css('position', 'absolute');
$dropdown.css('display', 'block');
$dropdown.appendTo('body');
});
$(document).on('hide.bs.dropdown', '.table-responsive', function (e) {
// Hide the dropdown menu bound to this button
$(e.target).data('dropdown-menu').css('display', 'none');
});
You can check with this command systemctl status docker
it will show the status of the docker. If you want to start you can use systemctl start docker
instead of systemctl
you can try also with service
, service docker status
and service docker start
respectively.
In case, it is a django backend application, you can do something like this.
docker exec -it container_id python manage.py dbshell
Let's assume you want to overwrite the same file:
import json
with open('data.json', 'r') as data_file:
data = json.load(data_file)
for element in data:
element.pop('hours', None)
with open('data.json', 'w') as data_file:
data = json.dump(data, data_file)
dict.pop(<key>, not_found=None)
is probably what you where looking for, if I understood your requirements. Because it will remove the hours
key if present and will not fail if not present.
However I am not sure I understand why it makes a difference to you whether the hours key contains some days or not, because you just want to get rid of the whole key / value pair, right?
Now, if you really want to use del
instead of pop
, here is how you could make your code work:
import json
with open('data.json') as data_file:
data = json.load(data_file)
for element in data:
if 'hours' in element:
del element['hours']
with open('data.json', 'w') as data_file:
data = json.dump(data, data_file)
EDIT So, as you can see, I added the code to write the data back to the file. If you want to write it to another file, just change the filename in the second open statement.
I had to change the indentation, as you might have noticed, so that the file has been closed during the data cleanup phase and can be overwritten at the end.
with
is what is called a context manager, whatever it provides (here the data_file file descriptor) is available ONLY within that context. It means that as soon as the indentation of the with
block ends, the file gets closed and the context ends, along with the file descriptor which becomes invalid / obsolete.
Without doing this, you wouldn't be able to open the file in write mode and get a new file descriptor to write into.
I hope it's clear enough...
SECOND EDIT
This time, it seems clear that you need to do this:
with open('dest_file.json', 'w') as dest_file:
with open('source_file.json', 'r') as source_file:
for line in source_file:
element = json.loads(line.strip())
if 'hours' in element:
del element['hours']
dest_file.write(json.dumps(element))
If ad hoc updates to system catalog is "not supported", or if you get a "Msg 5808" then you will need to configure with override like this:
EXEC sp_configure 'show advanced options', 1
RECONFIGURE with override
GO
EXEC sp_configure 'ad hoc distributed queries', 1
RECONFIGURE with override
GO

Reason why FB automatically stopped my app was that I had not provided a valid PRIVACY policy & terms URL. So, make sure you enter these URLs on your app basic settings page and then make your app PUBLIC from app review page as described in above posts.
called_from
must be null
. Add a test against that condition like
if (called_from != null && called_from.equalsIgnoreCase("add")) {
or you could use Yoda conditions (per the Advantages in the linked Wikipedia article it can also solve some types of unsafe null
behavior they can be described as placing the constant portion of the expression on the left side of the conditional statement)
if ("add".equalsIgnoreCase(called_from)) { // <-- safe if called_from is null
// Save search term state to React Hooks with spread operator and wrapper function
// Using .concat(), no wrapper function (not recommended)
setSearches(searches.concat(query))
// Using .concat(), wrapper function (recommended)
setSearches(searches => searches.concat(query))
// Spread operator, no wrapper function (not recommended)
setSearches([...searches, query])
// Spread operator, wrapper function (recommended)
setSearches(searches => [...searches, query])

Use document.location.reload(true)
it will not load page from cache.
%d
prints an integer: it will print the ascii representation of your character. What you need is %c
:
printf("%c", ch);
printf("%d", '\0');
prints the ascii representation of '\0'
, which is 0 (by escaping 0 you tell the compiler to use the ascii value 0.
printf("%d", sizeof('\n'));
prints 4 because a character literal is an int
, in C, and not a char
.
To improve Alexander's solution from the Python 2.6 (and in Python 3.x) you can use helper module curses.ascii and use curses.ascii.isascii() function or various other: https://docs.python.org/2.6/library/curses.ascii.html
from curses import ascii
def isascii(s):
return all(ascii.isascii(c) for c in s)
I could not really work with the above. So this might help someone.

.then(

)

parameter.
In simple, Normalisation is Reduction of Redundancies.
Examples of Redundancies:
a) white spaces outside of the root/document tags(...<document></document>...)
b) white spaces within start tag (<...>) and end tag (</...>)
c) white spaces between attributes and their values (ie. spaces between key name and =")
d) superfluous namespace declarations
e) line breaks/white spaces in texts of attributes and tags
f) comments etc...
It may be that your condas channels need a wakeup call... with
conda update --all
For me it worked. More information: https://www.anaconda.com/keeping-anaconda-date/
What you actually created with:
MyType[] list = []
Was fixed size array (not list) with size of 0. You can create fixed size array of size for example 4 with:
MyType[] array = new MyType[4]
But there's no add method of course.
If you create list with def
it's something like creating this instance with Object
(You can read more about def
here). And []
creates empty ArrayList
in this case.
So using def list = []
you can then append new items with add()
method of ArrayList
list.add(new MyType())
Or more groovy way with overloaded left shift operator:
list << new MyType()
You probably just want
git branch --contains branch-to-delete
This will list all branches which contain the commits from "branch-to-delete". If it reports more than just "branch-to-delete", the branch has been merged.
Your alternatives are really just rev-list syntax things. e.g. git log one-branch..another-branch
shows everything that one-branch
needs to have everything another-branch
has.
You may also be interested in git show-branch
as a way to see what's where.
Here (this) is a object which contains all features/properties of the dom element. you can see by
console.log(this);
This will display all attributes properties of the dom element with hierarchy. You can manipulate the dom element by this.
Also describe on the below link:-
One way
SELECT t1.*
FROM db.table t1
WHERE exists
(SELECT *
FROM db.table t2
where t1.pk != t2.pk
and t1.someField = t2.someField)
I seconded Matthieu answer
I commented #Listen 443 in httpd-ssl file and apache can be started
Because the file already has VirtualHost default:443
For me it was a wrong maven dependency deceleration, so here is the correct way:
for sqljdbc4 use: sqljdbc4 dependency
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>sqljdbc4</artifactId>
<version>4.0</version>
</dependency>
for sqljdbc42 use: sqljdbc42 dependency
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>sqljdbc42</artifactId>
<version>6.0.8112</version>
</dependency>
Your problem is basically that you never specified the right path to the file.
Try instead, from your main script:
from folder.file import Klasa
Or, with from folder import file
:
from folder import file
k = file.Klasa()
Or again:
import folder.file as myModule
k = myModule.Klasa()
window.location
will affect to your browser target.
document.location will only affect to your browser and frame/iframe.
Since it's an async operation the onreadystatechange
may happen before the value has loaded in the responseText, try using a window.setTimeout(function () { JSON.parse(xhr.responseText); }, 1000);
to see if the error persists? BOL
Try like this
Pass Camera Intent like below
Intent intent = new Intent(this);
startActivityForResult(intent, REQ_CAMERA_IMAGE);
And after capturing image Write an OnActivityResult
as below
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo);
knop.setVisibility(Button.VISIBLE);
// CALL THIS METHOD TO GET THE URI FROM THE BITMAP
Uri tempUri = getImageUri(getApplicationContext(), photo);
// CALL THIS METHOD TO GET THE ACTUAL PATH
File finalFile = new File(getRealPathFromURI(tempUri));
System.out.println(mImageCaptureUri);
}
}
public Uri getImageUri(Context inContext, Bitmap inImage) {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
String path = Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
return Uri.parse(path);
}
public String getRealPathFromURI(Uri uri) {
String path = "";
if (getContentResolver() != null) {
Cursor cursor = getContentResolver().query(uri, null, null, null, null);
if (cursor != null) {
cursor.moveToFirst();
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
path = cursor.getString(idx);
cursor.close();
}
}
return path;
}
And check log
Edit:
Lots of people are asking how to not get a thumbnail. You need to add this code instead for the getImageUri
method:
public Uri getImageUri(Context inContext, Bitmap inImage) {
Bitmap OutImage = Bitmap.createScaledBitmap(inImage, 1000, 1000,true);
String path = MediaStore.Images.Media.insertImage(inContext.getContentResolver(), OutImage, "Title", null);
return Uri.parse(path);
}
The other method Compresses the file. You can adjust the size by changing the number 1000,1000
I found out it was:
$ git fetch upstream
$ git merge upstream/master
adjust video start and end time when using the video tag in html5;
http://www.yoursite.com/yourfolder/yourfile.mp4#t=5,15
where left of comma is start time in seconds, right of comma is end time in seconds. drop the comma and end time to effect the start time only.
I've did a "Update-Package –reinstall Microsoft.AspNet.Mvc" to fix it in Visual Studio 2015.
Since the above only works for python 2.x for python 3.x (specifically 3.5) is similar but with a slight modification:
import readline
for i in range(readline.get_current_history_length()):
print (readline.get_history_item(i + 1))
note the extra ()
(using shell scripts to parse .python_history or using python to modify the above code is a matter of personal taste and situation imho)
I think you should do it something like this.
class myURL {
protected $baseURL, $requestParameters;
public function __construct ($newURL) {
$this->baseurl = $newURL;
$this->requestParameters = array();
}
public function addParameter ($parameter) {
$this->requestParameters[] = $parameter;
}
public function __toString () {
return $this->baseurl.
( count($this->requestParameters) ?
'?'.implode('&', $this->requestParameters) :
''
);
}
}
$url1 = new myURL ('http://www.acme.com');
$url2 = new myURL ('http://www.acme.com');
$url2->addParameter('sort=popular');
$url2->addParameter('category=action');
$url1->addParameter('category=action');
echo $url1."\n".$url2;
string.Join(" ,", myArrayList.ToArray());
This will work with .net framework 4.5
If you don't want to add a new dependency just to do this (like HTMLEntities
) and you're already using Hpricot
, it can both escape and unescape for you. It handles much more than CGI
:
Hpricot.uxs "foo bär"
=> "foo bär"
Update: March 2020
According to Android developer official documentation, AsyncTask is now deprecated.
It's recommended to use kotlin corourines instead. Simply, it allows you to write asynchronous tasks in a sequential style.
I recommend you try to suppress specific warnings by using @SuppressWarnings("squid:S2078")
.
For suppressing multiple warnings you can do it like this @SuppressWarnings({"squid:S2078", "squid:S2076"})
There is also the //NOSONAR
comment that tells SonarQube to ignore all errors for a specific line.
Finally if you have the proper rights for the user interface you can issue a flag as a false positive directly from the interface.
The reason why I recommend suppression of specific warnings is that it's a better practice to block a specific issue instead of using //NOSONAR
and risk a Sonar issue creeping in your code by accident.
You can read more about this in the FAQ
Edit: 6/30/16 SonarQube is now called SonarLint
In case you are wondering how to find the squid number. Just click on the Sonar message (ex. Remove this method to simply inherit it.
) and the Sonar issue will expand.
On the bottom left it will have the squid number (ex. squid:S1185
Maintainability > Understandability)
So then you can suppress it by @SuppressWarnings("squid:S1185")
If you are using Moment.js then you can use there built in Duration
object
const duration = moment.duration(4825, 'seconds');
const h = duration.hours(); // 1
const m = duration.minutes(); // 20
const s = duration.seconds(); // 25
The native DOM method does the right thing:
$('.cssbuttongo')[0].click();
^
Important!
This works regardless of whether the href
is a URL, a fragment (e.g. #blah
) or even a javascript:
.
Note that this calls the DOM click
method instead of the jQuery click
method (which is very incomplete and completely ignores href
).

<div mce_keep="true"><section name="handlers" overrideModeDefault="Deny" /> change this value from "Deny" to "Allow"</div>
<div mce_keep="true"><section name="modules" allowDefinition="MachineToApplication" overrideModeDefault="Deny" /> change this value from "Deny" to "Allow"</div>
A few years ago I inherited a python (2.7.1) project running under Django-1.2.3 and now was asked to enhance it with QR possibilities. Got the same problem and did not find pip or apt-get either. So I solved it in a totally different but easy way. I /bin/vi-ed the setup.py and changed the line "from setuptools import setup" into: "from distutils.core import setup" That did it for me, so I thought I should post this for other users running old pythons.

Modern browsers support native querySelectorAll
so you can do:
document.querySelectorAll('[data-foo="value"]');

You can use jQuery to support obsolete browsers (IE9 and older):

I accidentally created two times create_users_table. It overrided some classes and turned rollback into ErrorException.
What you need to do is find autoload_classmap.php in vendor/composer folder and look for the specific line of code such as
'CreateUsersTable' => $baseDir . '/app/database/migrations/2013_07_04_014051_create_users_table.php',
and edit path. Then your rollback should be fine.
mayby one little change from the top answer, because DB_NAME()
returns always content db of execution. so, for me better like below:
sp_MSforeachdb 'select DB_name(db_id(''?'')) as DB, * From ?..sysobjects where xtype in (''U'', ''P'') And name like ''[_]x[_]%'''
In my case I was looking for tables their names started with _x_
Cheers, Ondrej
There are at least two ways to do that:
defining context param in web.xml – that breaks "one package for all environments" statement. I don't recommend that
defining system property -Dspring.profiles.active=your-active-profile
I believe that defining system property is a much better approach. So how to define system property for Tomcat? On the internet I could find a lot of advice like "modify catalina.sh" because you will not find any configuration file for doing stuff like that. Modifying catalina.sh is a dirty unmaintainable solution. There is a better way to do that.
Just create file setenv.sh in Tomcat's bin directory with content:
JAVA_OPTS="$JAVA_OPTS -Dspring.profiles.active=dev"
and it will be loaded automatically during running catalina.sh start or run.
Here is a blog describing the above solution.
Here is what I'd use for all links on a page...
document.body.addEventListener(function(event) {
if (event.target.href && event.target.target != "_blank") {
event.preventDefault();
window.location = this.href;
}
});
If you're using jQuery or Zepto...
$("body").on("click", "a", function(event) {
event.target.target != "_blank" && (window.location = event.target.href);
});
||
)?The double pipe operator (||
) is the logical OR
operator . In most languages it works the following way:
false
, it checks the second value. If that's true
, it returns true
and if the second value is false
, it returns false
.true
, it always returns true
, no matter what the second value is.So basically it works like this function:
function or(x, y) {
if (x) {
return true;
} else if (y) {
return true;
} else {
return false;
}
}
If you still don't understand, look at this table:
| true false
------+---------------
true | true true
false | true false
In other words, it's only false when both values are false.
JavaScript is a bit different, because it's a loosely typed language. In this case it means that you can use ||
operator with values that are not booleans. Though it makes no sense, you can use this operator with for example a function and an object:
(function(){}) || {}
If values are not boolean, JavaScript makes implicit conversion to boolean. It means that if the value is falsey (e.g. 0
, ""
, null
, undefined
(see also All falsey values in JavaScript)), it will be treated as false
; otherwise it's treated as true
.
So the above example should give true
, because empty function is truthy. Well, it doesn't. It returns the empty function. That's because JavaScript's ||
operator doesn't work as I wrote at the beginning. It works the following way:
Surprised? Actually, it's "compatible" with the traditional ||
operator. It could be written as following function:
function or(x, y) {
if (x) {
return x;
} else {
return y;
}
}
If you pass a truthy value as x
, it returns x
, that is, a truthy value. So if you use it later in if
clause:
(function(x, y) {
var eitherXorY = x || y;
if (eitherXorY) {
console.log("Either x or y is truthy.");
} else {
console.log("Neither x nor y is truthy");
}
}(true/*, undefined*/));
you get "Either x or y is truthy."
.
If x
was falsey, eitherXorY
would be y
. In this case you would get the "Either x or y is truthy."
if y
was truthy; otherwise you'd get "Neither x nor y is truthy"
.
Now, when you know how ||
operator works, you can probably make out by yourself what does x = x || y
mean. If x
is truthy, x
is assigned to x
, so actually nothing happens; otherwise y
is assigned to x
. It is commonly used to define default parameters in functions. However, it is often considered a bad programming practice, because it prevents you from passing a falsey value (which is not necessarily undefined
or null
) as a parameter. Consider following example:
function badFunction(/* boolean */flagA) {
flagA = flagA || true;
console.log("flagA is set to " + (flagA ? "true" : "false"));
}
It looks valid at the first sight. However, what would happen if you passed false
as flagA
parameter (since it's boolean, i.e. can be true
or false
)? It would become true
. In this example, there is no way to set flagA
to false
.
It would be a better idea to explicitly check whether flagA
is undefined
, like that:
function goodFunction(/* boolean */flagA) {
flagA = typeof flagA !== "undefined" ? flagA : true;
console.log("flagA is set to " + (flagA ? "true" : "false"));
}
Though it's longer, it always works and it's easier to understand.
You can also use the ES6 syntax for default function parameters, but note that it doesn't work in older browsers (like IE). If you want to support these browsers, you should transpile your code with Babel.
See also Logical Operators on MDN.

Put everything in a script and run it via cron (scheduler). Exporting objects can be tricky when advanced features are used. Don't be surprised if you need to add some more exceptions to the above code.
You need to reverse the nesting inside the generate block:
genvar c;
generate
for (c = 0; c < ROWBITS; c = c + 1) begin: test
always @(posedge sysclk) begin
temp[c] <= 1'b0;
end
end
endgenerate
Technically, this generates four always blocks:
always @(posedge sysclk) temp[0] <= 1'b0;
always @(posedge sysclk) temp[1] <= 1'b0;
always @(posedge sysclk) temp[2] <= 1'b0;
always @(posedge sysclk) temp[3] <= 1'b0;
In this simple example, there's no difference in behavior between the four always blocks and a single always block containing four assignments, but in other cases there could be.
The genvar-dependent operation needs to be resolved when constructing the in-memory representation of the design (in the case of a simulator) or when mapping to logic gates (in the case of a synthesis tool). The always @posedge
doesn't have meaning until the design is operating.
Subject to certain restrictions, you can put a for loop inside the always block, even for synthesizable code. For synthesis, the loop will be unrolled. However, in that case, the for loop needs to work with a reg
, integer
, or similar. It can't use a genvar
, because having the for loop inside the always block describes an operation that occurs at each edge of the clock, not an operation that can be expanded statically during elaboration of the design.
If you need only one upper case and special character then this should work:

.str.get
This is the simplest to specify string methods
# Setup
df = pd.DataFrame({'A': ['xyz', 'abc', 'foobar'], 'B': [123, 456, 789]})
df
A B
0 xyz 123
1 abc 456
2 foobar 789
df.dtypes
A object
B int64
dtype: object
For string (read:object
) type columns, use
df['C'] = df['A'].str[0]
# Similar to,
df['C'] = df['A'].str.get(0)
.str
handles NaNs by returning NaN as the output.
For non-numeric columns, an .astype
conversion is required beforehand, as shown in @Ed Chum's answer.
# Note that this won't work well if the data has NaNs.
# It'll return lowercase "n"
df['D'] = df['B'].astype(str).str[0]
df
A B C D
0 xyz 123 x 1
1 abc 456 a 4
2 foobar 789 f 7
There is enough evidence to suggest a simple list comprehension will work well here and probably be faster.
# For string columns
df['C'] = [x[0] for x in df['A']]
# For numeric columns
df['D'] = [str(x)[0] for x in df['B']]
df
A B C D
0 xyz 123 x 1
1 abc 456 a 4
2 foobar 789 f 7
If your data has NaNs, then you will need to handle this appropriately with an if
/else
in the list comprehension,
df2 = pd.DataFrame({'A': ['xyz', np.nan, 'foobar'], 'B': [123, 456, np.nan]})
df2
A B
0 xyz 123.0
1 NaN 456.0
2 foobar NaN
# For string columns
df2['C'] = [x[0] if isinstance(x, str) else np.nan for x in df2['A']]
# For numeric columns
df2['D'] = [str(x)[0] if pd.notna(x) else np.nan for x in df2['B']]
A B C D
0 xyz 123.0 x 1
1 NaN 456.0 NaN 4
2 foobar NaN f NaN
Let's do some timeit tests on some larger data.

%timeit df.assign(D=df['B'].astype(str).str[0])
%timeit df.assign(C=[x[0] for x in df['A']])
%timeit df.assign(D=[str(x)[0] for x in df['B']])

List comprehensions are 4x faster.
If you take Erics answer a little further you can actually create a pretty decent implementation of abstract classes, with full support for polymorphism and the ability to call implemented methods from the base class. Let's start with the code:
/**
* The interface defines all abstract methods and extends the concrete base class
*/
interface IAnimal extends Animal {
speak() : void;
}
/**
* The abstract base class only defines concrete methods & properties.
*/
class Animal {
private _impl : IAnimal;
public name : string;
/**
* Here comes the clever part: by letting the constructor take an
* implementation of IAnimal as argument Animal cannot be instantiated
* without a valid implementation of the abstract methods.
*/
constructor(impl : IAnimal, name : string) {
this.name = name;
this._impl = impl;
// The `impl` object can be used to delegate functionality to the
// implementation class.
console.log(this.name + " is born!");
this._impl.speak();
}
}
class Dog extends Animal implements IAnimal {
constructor(name : string) {
// The child class simply passes itself to Animal
super(this, name);
}
public speak() {
console.log("bark");
}
}
var dog = new Dog("Bob");
dog.speak(); //logs "bark"
console.log(dog instanceof Dog); //true
console.log(dog instanceof Animal); //true
console.log(dog.name); //"Bob"
Since the Animal
class requires an implementation of IAnimal
it's impossible to construct an object of type Animal
without having a valid implementation of the abstract methods. Note that for polymorphism to work you need to pass around instances of IAnimal
, not Animal
. E.g.:
//This works
function letTheIAnimalSpeak(animal: IAnimal) {
console.log(animal.name + " says:");
animal.speak();
}
//This doesn't ("The property 'speak' does not exist on value of type 'Animal')
function letTheAnimalSpeak(animal: Animal) {
console.log(animal.name + " says:");
animal.speak();
}
The main difference here with Erics answer is that the "abstract" base class requires an implementation of the interface, and thus cannot be instantiated on it's own.
Thankfully, with C++11 there is also the more pleasing approach of using raw string literals.
printf("She said \"time flies like an arrow, but fruit flies like a banana\".");
Becomes:
printf(R"(She said "time flies like an arrow, but fruit flies like a banana".)");
With respect to the addition of brackets after the opening quote, and before the closing quote, note that they can be almost any combination of up to 16 characters, helping avoid the situation where the combination is present in the string itself. Specifically:
any member of the basic source character set except: space, the left parenthesis (, the right parenthesis ), the backslash , and the control characters representing horizontal tab, vertical tab, form feed, and newline" (N3936 §2.14.5 [lex.string] grammar) and "at most 16 characters" (§2.14.5/2)
How much clearer it makes this short strings might be debatable, but when used on longer formatted strings like HTML or JSON, it's unquestionably far clearer.
Here are a couple of reasons for having different naming of C vs C++ headers:
Remember, C is not C++ and it can be very dangerous to mix and match unless you know what you are doing. Naming your sources appropriately helps you tell the languages apart.
You still have to wrap it in an ISERROR, but you could use MATCH()
instead of VLOOKUP()
:
Returns the relative position of an item in an array that matches a specified value in a specified order. Use MATCH instead of one of the LOOKUP functions when you need the position of an item in a range instead of the item itself.
Here's a complete example, assuming you're looking for the word "key" in a range of cells:
=IF(ISERROR(MATCH("key",A5:A16,FALSE)),"missing","found")
The FALSE
is necessary to force an exact match, otherwise it will look for the closest value.
Angular.js has a built-in date filter.
// in your controller:
$scope.date = '20140313T00:00:00';
// in your view, date property, filtered with date filter and format 'MM/dd/yyyy'
<p ng-bind="date | date:'MM/dd/yyyy'"></p>
// produces
03/13/2014
You can see the supported date formats in the source for the date filter.
edit:
If you're trying to get the correct format in the datepicker (not clear if you're using datepicker or just trying to use it's formatter), those supported format strings are here: https://api.jqueryui.com/datepicker/
use ack its simple.
just type ack <string to be searched>
try this
<?xml version="1.0" encoding="utf-8"?>

android:topRightRadius="0dp"
android:bottomRightRadius="0dp" />
</shape>
I think @Evert has the right answer:
plt.scatter(dates,values)
plt.plot(dates, values)
plt.show()
Which is pretty much the same as
plt.plot(dates, values, '-o')
plt.show()
or whatever linestyle you prefer.
In my case, I had a nested list as the series that I wanted to use as an input.
First check: If
df['nestedList'][0]
outputs a list like [1,2,3]
, you have a nested list.
Then check if you still get the error when changing to input df['nestedList'][0]
.
Then your next step is probably to concatenate all nested lists into one unnested list, using
[item for sublist in df['nestedList'] for item in sublist]
This flattening of the nested list is borrowed from How to make a flat list out of list of lists?.
I Know this is a old question, and Pawel has given the correct answer, I just wanted to show a code example of how to do some string processing, and avoid an extra class for the list of a primitive type.

A couple of wires are crossed here. The various autoplay
settings that you're working with only affect whether the SWF's root timeline starts out paused or not. So if your SWF had a timeline animation, or if it had an embedded video on the root timeline, then these settings would do what you're after.
However, the SWF you're working with almost certainly has only one frame on its timeline, so these settings won't affect playback at all. That one frame contains some flavor of video playback component, which contains ActionScript that controls how the video behaves. To get that player component to start of paused, you'll have to change the settings of the component itself.
Without knowing more about where the content came from it's hard to say more, but when one publishes from Flash, video player components normally include a parameter for whether to autoplay. If your SWF is being published by an application other than Flash (Captivate, I suppose, but I'm not up on that) then your best bet would be to check the settings for that app. Anyway it's not something you can control from the level of the HTML page. (Unless you were talking to the SWF from JavaScript, and for that to work the video component would have to be designed to allow it.)
To check the data types after, for example, an import from a file
def printColumnInfo(df):
template="%-8s %-30s %s"
print(template % ("Type", "Column Name", "Example Value"))
print("-"*53)
for c in df.columns:
print(template % (df[c].dtype, c, df[c].iloc[1]) )
Illustrative output:

MySQL recommends using indexes for a variety of reasons including elimination of rows between conditions: http://dev.mysql.com/doc/refman/5.0/en/mysql-indexes.html
This makes your datetime column an excellent candidate for an index if you are going to be using it in conditions frequently in queries. If your only condition is BETWEEN NOW() AND DATE_ADD(NOW(), INTERVAL 30 DAY)
and you have no other index in the condition, MySQL will have to do a full table scan on every query. I'm not sure how many rows are generated in 30 days, but as long as it's less than about 1/3 of the total rows it will be more efficient to use an index on the column.
Your question about creating an efficient database is very broad. I'd say to just make sure that it's normalized and all appropriate columns are indexed (i.e. ones used in joins and where clauses).
Instance methods => invoked on specific instance of a specific class. Method wants to know upon which class it was invoked. The way it happens there is a invisible parameter called 'this'. Inside of 'this' we have members of instance class already set with values. 'This' is not a variable. It's a value, you cannot change it and the value is reference to the receiver of the call. Ex: You call repairmen(instance method) to fix your TV(actual program). He comes with tools('this' parameter). He comes with specific tools needed for fixing TV and he can fix other things also.
In static methods => there is no such thing as 'this'. Ex: The same repairman (static method). When you call him you have to specify which repairman to call(like electrician). And he will come and fix your TV only. But, he doesn't have tools to fix other things (there is no 'this' parameter).
Static methods are usually useful for operations that don't require any data from an instance of the class (from 'this') and can perform their intended purpose solely using their arguments.
Try this.
public class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
// Web API configuration and services
var json = config.Formatters.JsonFormatter;
json.SupportedMediaTypes.Add(new System.Net.Http.Headers.MediaTypeHeaderValue("application/json"));
config.Formatters.Remove(config.Formatters.XmlFormatter);
// Web API routes
config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional , Action =RouteParameter.Optional }
);
}
}

The method show()
must be called from the User-Interface (UI) thread, while doInBackground()
runs on different thread which is the main reason why AsyncTask
was designed.
You have to call show()
either in onProgressUpdate()
or in onPostExecute()
.
For example:
class ExampleTask extends AsyncTask<String, String, String> {
// Your onPreExecute method.
@Override
protected String doInBackground(String... params) {
// Your code.
if (condition_is_true) {
this.publishProgress("Show the dialog");
}
return "Result";
}
@Override
protected void onProgressUpdate(String... values) {
super.onProgressUpdate(values);
connectionProgressDialog.dismiss();
downloadSpinnerProgressDialog.show();
}
}

It really really does make the flow of a sequence with several lookups and optionals much more concise and clear and reduces lots of if nesting. See Erica Sadun post on replacing Ifs. .... Could get carried away, an example below:

guard let foundLink = filteredLinks.first else {return ("<Person> cannot go in that direction.", nil, nil)}
guard filteredLinks.count == 1 else {return ("<Person> cannot decide which route to take.", nil, nil)}
guard let nextLocation = foundLink.toLocation else {return ("<Person> cannot go in that direction.", nil, nil)}
See if that sticks.
Not the best way but If you are using mac or linux even in windows you can set alias for different registries.
##############NPM ALIASES######################
alias npm-default='npm config set registry https://registry.npmjs.org'
alias npm-sinopia='npm config set registry http://localhost:4873/'
For anyone trying to set this for Rails projects, add
set directory=tmp,/tmp
into your
~/.vimrc
So the .swp files will be in their natural location - the tmp directory (per project).
the following code , install and uninstall the Service,
Open the command prompt and run the program as an administrator and fire the below command and press enter.

Yes, a GUID should always be unique. It is based on both hardware and time, plus a few extra bits to make sure it's unique. I'm sure it's theoretically possible to end up with two identical ones, but extremely unlikely in a real-world scenario.
Here's a great article by Raymond Chen on Guids:

Extract characters from a string:
var str = "Hello world!";
var res = str.substring(1,4);
The result of res
will be:

$('.dep_buttons').mouseover(function(){
$(this).text().substring(0,25);
if($(this).text().length > 30) {
$(this).stop().animate({height:"150px"},150);
}
$(".dep_buttons").mouseout(function(){
$(this).stop().animate({height:"40px"},150);

Invoke mysql with the -N
(the alias for -N
is --skip-column-names
) option:
mysql -N ...
use testdb;
select * from names;
+------+-------+
| 1 | pete |
| 2 | john |
| 3 | mike |
+------+-------+
3 rows in set (0.00 sec)
Credit to ErichBSchulz for pointing out the -N alias.
To remove the grid (the vertical and horizontal lines) around the results use -s
(--silent
). Columns are separated with a TAB
character.
mysql -s ...
use testdb;
select * from names;
id name
1 pete
2 john
3 mike
To output the data with no headers and no grid just use both -s
and -N
.
mysql -sN ...
you should try:
request.url
It suppose to work always, even on localhost (just did it).
Hope this layout works, take it to the binary representation with an XOR:
66h = 102 decimal = 01100110 binary
FAh = 250 decimal = 11111010 binary
------------------------------------
10011100 binary <------ that's 9Ch/156 decimal
but the wiki I linked earlier will give you more details if needed...thats what it looks like they are doing in the screenshot you provided
I have the same error and it fixed it including in the file the following

Blockquote
Using concatenation in Oracle SQL is very easy and interesting. But don't know much about MS-SQL.
Blockquote
Here we go for Oracle :
Syntax:
SQL> select First_name||Last_Name as Employee
from employees;
EllenAbel SundarAnde MozheAtkinson
Here AS: keyword used as alias. We can concatenate with NULL values. e.g. : columnm1||Null
Suppose any of your columns contains a NULL value then the result will show only the value of that column which has value.
You can also use literal character string in concatenation.
e.g.
select column1||' is a '||column2
from tableName;
Result: column1 is a column2.
in between literal should be encolsed in single quotation. you cna exclude numbers.
NOTE: This is only for oracle server//SQL.

First you have to check login existence using syslogins view:
IF NOT EXISTS
(SELECT name
FROM master.sys.server_principals
WHERE name = 'YourLoginName')
BEGIN
CREATE LOGIN [YourLoginName] WITH PASSWORD = N'password'
END
Then you have to check your database existence:
USE your_dbname
IF NOT EXISTS
(SELECT name
FROM sys.database_principals
WHERE name = 'your_dbname')
BEGIN
CREATE USER [your_dbname] FOR LOGIN [YourLoginName]
END
Shallow copy:
Some members of the copy may reference the same objects as the original:
class X
{
private:
int i;
int *pi;
public:
X()
: pi(new int)
{ }
X(const X& copy) // <-- copy ctor
: i(copy.i), pi(copy.pi)
{ }
};
Here, the pi
member of the original and copied X
object will both point to the same int
.
Deep copy:
All members of the original are cloned (recursively, if necessary). There are no shared objects:
class X
{
private:
int i;
int *pi;
public:
X()
: pi(new int)
{ }
X(const X& copy) // <-- copy ctor
: i(copy.i), pi(new int(*copy.pi)) // <-- note this line in particular!
{ }
};
Here, the pi
member of the original and copied X
object will point to different int
objects, but both of these have the same value.
The default copy constructor (which is automatically provided if you don't provide one yourself) creates only shallow copies.
Correction: Several comments below have correctly pointed out that it is wrong to say that the default copy constructor always performs a shallow copy (or a deep copy, for that matter). Whether a type's copy constructor creates a shallow copy, or deep copy, or something in-between the two, depends on the combination of each member's copy behaviour; a member's type's copy constructor can be made to do whatever it wants, after all.
Here's what section 12.8, paragraph 8 of the 1998 C++ standard says about the above code examples:
The implicitly defined copy constructor for class
X
performs a memberwise copy of its subobjects. [...] Each subobject is copied in the manner appropriate to its type: [...] [I]f the subobject is of scalar type, the builtin assignment operator is used.
I think it is confusing to think of it in terms of negative numbers. Since it is a logarithm think of the negative values the same way you think of powers of ten. 10^3 = 1000 while 10^-3 = 0.001.
With this in mind and using the formulas from S Lists's answer (and assuming our base power is 1mW in all these cases) we can build a little table:
|--------|-------------------|
| P(dBm) | P(mW) |
|--------|-------------------|
| 50 | 100000 |
| 40 | 10000 | strong transmitter
| 30 | 1000 | ^
| 20 | 100 | |
| 10 | 10 | |
| 0 | 1 |
| -10 | 0.1 |
| -20 | 0.01 |
| -30 | 0.001 |
| -40 | 0.0001 |
| -50 | 0.00001 | |
| -60 | 0.000001 | |
| -70 | 0.0000001 | v
| -80 | 0.00000001 | sensitive receiver
| -90 | 0.000000001 |
|--------|-------------------|
When I think of it like this I find that it's easier to see that the more negative the dBm value then the farther to the right of the decimal the actual power value is.
When it comes to mobile networks, it not so much that they aren't powerful enough, rather it is that they are more sensitive. When you see receivers specs with dBm far into the negative values, then what you are seeing is more sensitive equipment.
Normally you would want your transmitter to be powerful (further in to the positives) and your receiver to be sensitive (further in to the negatives).

Use the built-in time
keyword:
$ help time time: time [-p] PIPELINE Execute PIPELINE and print a summary of the real time, user CPU time, and system CPU time spent executing PIPELINE when it terminates. The return status is the return status of PIPELINE. The `-p' option prints the timing summary in a slightly different format. This uses the value of the TIMEFORMAT variable as the output format.
Example:
$ time sleep 2

Check out the BeamIt open source project. It will connect via bluetooth and WIFI (although it claims it does not do WIFI) and I have verified that it works well in my projects. It will allow peer to peer contact easily.
As for multiple connections, it is possible, but you will have to edit the BeamIt source code to make it possible. I suggest reading the GameKit programming guide
Tim Bray presented a concise step-by-step, stating that openConnection() does not establish an actual connection. Rather, an actual HTTP connection is not established until you call methods such as getInputStream() or getOutputStream().

If your API code is running on a node.js server then you need to focus your attention there, not in Apache or NGINX. Mikel is right, changing the API URL to HTTPS is the answer but if your API is calling a node.js server, it better be set up for HTTPS! And of course, the node.js server can be on any unused port, it doesn't have to be port 443.
Shorter way is do it as follows:
private char[][] table = {{'1', '2', '3'}, {'4', '5', '6'}, {'7', '8', '9'}};
There might be a cleverer way to go about this, but
intersect(intersect(a,b),c)
will do the job.
EDIT: More cleverly, and more conveniently if you have a lot of arguments:
Reduce(intersect, list(a,b,c))
DIVs inherently lack any useful meaning, other than to divide, of course.
Best course of action would be to add a meaningful class name to them, and style their individual margins in CSS.
<h1>Important Title</h1>
<div class="testimonials">...</div>
<div class="footer">...</div>
h1 {margin-bottom: 0.1em;}
div.testimonials {margin-bottom: 0.2em;}
div.footer {margin-bottom: 0;}
You should write the pickled data with a lower protocol number in Python 3. Python 3 introduced a new protocol with the number 3
(and uses it as default), so switch back to a value of 2
which can be read by Python 2.
Check the protocol
parameter in pickle.dump
. Your resulting code will look like this.
pickle.dump(your_object, your_file, protocol=2)
There is no protocol
parameter in pickle.load
because pickle
can determine the protocol from the file.
Please use below code
package com.myjava.string;
import java.util.StringTokenizer;
public class MyStrRemoveMultSpaces {
public static void main(String a[]){
String str = "String With Multiple Spaces";
StringTokenizer st = new StringTokenizer(str, " ");
StringBuffer sb = new StringBuffer();
while(st.hasMoreElements()){
sb.append(st.nextElement()).append(" ");
}
System.out.println(sb.toString().trim());
}
}

Something that is frustrating is that when you are developing in Eclipse MyClass.class.getProtectionDomain().getCodeSource().getLocation()
returns the /bin
directory which is great, but when you compile it to a jar, the path includes the /myjarname.jar
part which gives you illegal file names.
To have the code work both in the ide and once it is compiled to a jar, I use the following piece of code:
URL applicationRootPathURL = getClass().getProtectionDomain().getCodeSource().getLocation();
File applicationRootPath = new File(applicationRootPathURL.getPath());
File myFile;
if(applicationRootPath.isDirectory()){
myFile = new File(applicationRootPath, "filename");
}
else{
myFile = new File(applicationRootPath.getParentFile(), "filename");
}
Change display:inline to display:inline-block
.test {
width:200px;
display:inline-block;
overflow: auto;
white-space: nowrap;
margin:0px auto;
border:1px red solid;
}
Expanding on Felix Turner s response, here is how I would use this approach with the fetch
API.
async function createFile(){
let response = await fetch('http://127.0.0.1:8080/test.jpg');
let data = await response.blob();
let metadata = {
type: 'image/jpeg'
};
let file = new File([data], "test.jpg", metadata);
// ... do something with the file or return it
}
createFile();
For emulating Ruby syntax (and convey the semantics) of opening and reading a file, consider this implicit class (Scala 2.10 and upper),
import java.io.File
def open(filename: String) = new File(filename)
implicit class RichFile(val file: File) extends AnyVal {
def read = io.Source.fromFile(file).getLines.mkString("\n")
}
In this way,
open("file.txt").read
IDs must be unique in your document, meaning that you shouldn't do this:
<input type="checkbox" name="chk[]" id="chk[]" value="Apples" />
<input type="checkbox" name="chk[]" id="chk[]" value="Bananas" />
Instead, drop the ID, and then select them by name, or by a containing element:
<fieldset id="checkArray">
<input type="checkbox" name="chk[]" value="Apples" />
<input type="checkbox" name="chk[]" value="Bananas" />
</fieldset>
And now the jQuery:
var atLeastOneIsChecked = $('#checkArray:checkbox:checked').length > 0;
//there should be no space between identifier and selector
// or, without the container:
var atLeastOneIsChecked = $('input[name="chk[]"]:checked').length > 0;
Angular CLI now uses environment files to do this.
First, add an environments
section to the angular-cli.json
Something like :
{
"apps": [{
"environments": {
"prod": "environments/environment.prod.ts"
}
}]
}
And then inside the environment file (environments/environment.prod.ts
in this case), add something like :
export const environment = {
production: true,
"output-path": "./whatever/dist/"
};
now when you run :
ng build --prod
it will output to the ./whatever/dist/
folder.
Use the following command to do a clear screen instead of merely adding new lines ...
printf "\033c"
yes that's a 'printf' on the bash prompt.
You will probably want to define an alias though...
alias cls='printf "\033c"'
\033 == \x1B == 27 == ESC
So this becomes <ESC>c
which is the VT100 escape code for resetting the terminal. Here is some more information on terminal escape codes.
Here are a few other ways of doing it...
printf "\ec" #\e is ESC in bash
echo -en "\ec" #thanks @Jonathon Reinhart.
# -e Enable interpretation of of backslash escapes
# -n Do not output a new line
The above does not work on the KDE console (called Konsole) but there is hope! Use the following sequence of commands to clear the screen and the scroll-back buffer...
clear && echo -en "\e[3J"
Or perhaps use the following alias on KDE...
alias cls='clear && echo -en "\e[3J"'
I got the scroll-back clearing command from here.
mysql_connect("localhost", "root", "") or die(mysql_error()) ;
mysql_select_db("altabotanikk") or die(mysql_error()) ;
These are deprecated use the following..
// Connects to your Database
$link = mysqli_connect("localhost", "root", "", "");
and to insert data use the following
$sql = "INSERT INTO Table-Name (Column-Name)
VALUES ('$filename')" ;
Once I had written a program that handle the short (-h), long (--help) and non-option arguments in batch file. This techniques includes:
non-option arguments followed by a option arguments.
shift operator for those options that have no argument like '--help'.
two time shift operator for those options that require an argument.
loop through a label for processing all command line arguments.
Exit script and stop processing for those options that no need to require further action like '--help'.
Wrote help functions for user guidiness

Check your .git/config
file, particularly what tracking is present on fetch for that remote.
[remote "randomRemote"]
url = [email protected]:someUser/someRepo.git
fetch = +refs/heads/*:refs/remotes/randomRemote/*
If it has heads/*
pointing to randomRemote/*
, when you run git fetch randomRemote
, it will fetch all branches.
Then you can just checkout that branch.
Otherwise,
You need to add remote branches to the tracking using this. Check your .git/config
after running this. You will understand.
git remote set-branches --add randomRemote randomBranch
Run git fetch randomRemote
. This will fetch the remote branch.
Now you can run git checkout randomBranch
.

Now that's the thing about software development, there's no consistent knowledge about anything, everybody seems to have it their own way, but that's because it is a relatively young discipline anyway.
Here's my plain simple way,
trunk - The trunk directory contains the most current, approved, and merged body of work. Contrary to what many have confessed, my trunk is only for clean, neat, approved work, and not a development area, but rather a release area.
At some given point in time when the trunk seems all ready to release, then it is tagged and released.
branches - The branches directory contains experiments and ongoing work. Work under a branch stays there until is approved to be merged into the trunk. For me, this is the area where all the work is done.
For example: I can have an iteration-5 branch for a fifth round of development on the product, maybe a prototype-9 branch for a ninth round of experimenting, and so on.
tags - The tags directory contains snapshots of approved branches and trunk releases. Whenever a branch is approved to merge into the trunk, or a release is made of the trunk, a snapshot of the approved branch or trunk release is made under tags.
I suppose with tags I can jump back and forth through time to points interest quite easily.
From the macOS Terminal, use open

I've used this simple code in my codebase:
static public string ToReadableByteArray(byte[] bytes)
{
return string.Join(", ", bytes);
}
To use:
Console.WriteLine(ToReadableByteArray(bytes));
The thing is that decimal numbers defaults to double. And since double doesn't fit into float you have to tell explicitely you intentionally define a float. So go with:
float b = 3.6f;
You need to use the SUBTOTAL function. The SUBTOTAL function ignores rows that have been excluded by a filter.
The formula would look like this:
=SUBTOTAL(9,B1:B20)
The function number 9, tells it to use the SUM function on the data range B1:B20.
If you are 'filtering' by hiding rows, the function number should be updated to 109.
=SUBTOTAL(109,B1:B20)
The function number 109 is for the SUM function as well, but hidden rows are ignored.
I had this same problem for days. Keeping srand() out of the loop is a +. Also, dont assign rand() % 100 to any variable. Simply cout rand() % 100 in the loop. Try this:
srand (time(NULL));
(int t=0;t<10;t++)
{
cout << rand() % 100 << endl;
}
If you can afford working via the file data, you can do
find -mmin +14400 -delete
okay, here is my favorite xml way of doing it. I do this for the eclipse version so I can

As the above people stated, select PostGIS_full_version(); will answer your question. On my machine, where I'm running PostGIS 2.0 from trunk, I get the following output:
postgres=# select PostGIS_full_version();
postgis_full_version
-------------------------------------------------------------------------------------------------------------------------------------------------------
POSTGIS="2.0.0alpha4SVN" GEOS="3.3.2-CAPI-1.7.2" PROJ="Rel. 4.7.1, 23 September 2009" GDAL="GDAL 1.8.1, released 2011/07/09" LIBXML="2.7.3" USE_STATS
(1 row)
You do need to care about the versions of PROJ and GEOS that are included if you didn't install an all-inclusive package - in particular, there's some brokenness in GEOS prior to 3.3.2 (as noted in the postgis 2.0 manual) in dealing with geometry validity.
I have added an extra update method onto my repository base class that's similar to the update method generated by Scaffolding. Instead of setting the entire object to "modified", it sets a set of individual properties. (T is a class generic parameter.)
public void Update(T obj, params Expression<Func<T, object>>[] propertiesToUpdate)
{
Context.Set<T>().Attach(obj);
foreach (var p in propertiesToUpdate)
{
Context.Entry(obj).Property(p).IsModified = true;
}
}
And then to call, for example:
public void UpdatePasswordAndEmail(long userId, string password, string email)
{
var user = new User {UserId = userId, Password = password, Email = email};
Update(user, u => u.Password, u => u.Email);
Save();
}
I like one trip to the database. Its probably better to do this with view models, though, in order to avoid repeating sets of properties. I haven't done that yet because I don't know how to avoid bringing the validation messages on my view model validators into my domain project.
I had referenced this article and many others and did not find a clear cut concise response to help. I am offering my discovery, arrived at with some references from this thread, in the following:
Spring-Boot version: 1.3.5.RELEASE
Spring-Core version: 4.2.6.RELEASE
Dependency Management: Brixton.SR1
The following is the pertinent yaml excerpt:
tools:
toolList:
-
name: jira
matchUrl: http://someJiraUrl
-
name: bamboo
matchUrl: http://someBambooUrl
I created a Tools.class:
@Component
@ConfigurationProperties(prefix = "tools")
public class Tools{
private List<Tool> toolList = new ArrayList<>();
public Tools(){
//empty ctor
}
public List<Tool> getToolList(){
return toolList;
}
public void setToolList(List<Tool> tools){
this.toolList = tools;
}
}
I created a Tool.class:
@Component
public class Tool{
private String name;
private String matchUrl;
public Tool(){
//empty ctor
}
public String getName(){
return name;
}
public void setName(String name){
this.name= name;
}
public String getMatchUrl(){
return matchUrl;
}
public void setMatchUrl(String matchUrl){
this.matchUrl= matchUrl;
}
@Override
public String toString(){
StringBuffer sb = new StringBuffer();
String ls = System.lineSeparator();
sb.append(ls);
sb.append("name: " + name);
sb.append(ls);
sb.append("matchUrl: " + matchUrl);
sb.append(ls);
}
}
I used this combination in another class through @Autowired
@Component
public class SomeOtherClass{
private Logger logger = LoggerFactory.getLogger(SomeOtherClass.class);
@Autowired
private Tools tools;
/* excluded non-related code */
@PostConstruct
private void init(){
List<Tool> toolList = tools.getToolList();
if(toolList.size() > 0){
for(Tool t: toolList){
logger.info(t.toString());
}
}else{
logger.info("*****----- tool size is zero -----*****");
}
}
/* excluded non-related code */
}
And in my logs the name and matching url's were logged. This was developed on another machine and thus I had to retype all of the above so please forgive me in advance if I inadvertently mistyped.
I hope this consolidation comment is helpful to many and I thank the previous contributors to this thread!
My cause was different I referenced a web service then I got this message.
Then I changed my target .Net Framework 4.0 to .Net Framework 2.0 and re-refer my webservice. After a few changes problem solved. There is no error worked fine.
hope this helps!
The default port 1433 is used when there is only one SQL Server named instance running on the computer.
When multiple SQL Server named instances are running, they run by default under a dynamic port (49152–65535). In this scenario, an application will connect to the SQL Server Browser service port (UDP 1434) to get the dynamic port and then connect to the dynamic port directly.
It's simple and understandable. Just copy paste this code and your issue will get resolved.For more conditions just change the value in pattern.and your work will done.
<input type="text" pattern="[0-9]{0,}" oninvalid="this.setCustomValidity('Please enter only numeric value. Special character are not allowed.')" oninput="setCustomValidity('')">
With Java 8+, you can use the new Java time API:
to parse the time:
LocalTime time = LocalTime.parse("11:22")
to do date comparisons, you have LocalTime::isBefore
and LocalTime::isAfter
- note that these methods are strict
So you problem would be as simple as:
public static void main(String[] args) {
LocalTime time = LocalTime.parse("11:22");
System.out.println(isBetween(time, LocalTime.of(10, 0), LocalTime.of(18, 0)));
}
public static boolean isBetween(LocalTime candidate, LocalTime start, LocalTime end) {
return !candidate.isBefore(start) && !candidate.isAfter(end); // Inclusive.
}
For inclusive beginning but exclusive ending (half-open), use this line.
return !candidate.isBefore(start) && candidate.isBefore(end); // Exclusive of end.
Those look much like Bonjour / mDNS requests to me. Those packets use multicast IP address 224.0.0.251 and port 5353.
The most likely source for this is Apple iTunes, which comes pre-installed on Mac computers (and is a popular install on Windows machines as well). Apple iTunes uses it to discover other iTunes-compatible devices in the same WiFi network.
mDNS is also used (primarily by Apple's Mac and iOS devices) to discover mDNS-compatible devices such as printers on the same network.
If this is a Linux box instead, it's probably the Avahi daemon then. Avahi is ZeroConf/Bonjour compatible and installed by default, but if you don't use DNS-SD or mDNS, it can be disabled.
There are two variants of CASE
, and you're not using the one that you think you are.
CASE case_value
WHEN when_value THEN statement_list
[WHEN when_value THEN statement_list] ...
[ELSE statement_list]
END CASE
Each condition is loosely equivalent to a if (case_value == when_value)
(pseudo-code).
However, you've put an entire condition as when_value
, leading to something like:
if (case_value == (case_value > 100))
Now, (case_value > 100)
evaluates to FALSE
, and is the only one of your conditions to do so. So, now you have:
if (case_value == FALSE)
FALSE
converts to 0
and, through the resulting full expression if (case_value == 0)
you can now see why the third condition fires.
Drop the first course_enrollment_settings
so that there's no case_value
, causing MySQL to know that you intend to use the second variant of CASE
:
CASE
WHEN search_condition THEN statement_list
[WHEN search_condition THEN statement_list] ...
[ELSE statement_list]
END CASE
Now you can provide your full conditionals as search_condition
.
Also, please read the documentation for features that you use.

Copy your source folder to somedir
:
cp -r srcdir
somedir
Remove all unneeded files:
find somedir -name '.svn' -exec rm -rf {} \+
launch scp from somedir
In case you have only one controller and you want to access every action on root you can skip controller name like this
routes.MapRoute(
"Default",
"{action}/{id}",
new { controller = "Home", action = "Index",
id = UrlParameter.Optional }
);
The most obvious solutions are already listed. Depending on where the query is sat (i.e. in application code) you can't always use IF statements and the inline CASE statements can get painful where lots of columns become conditional. Assuming Col1 + Col3 + Col7 are the same type, and likewise Col2, Col4 + Col8 you can do this:
SELECT Col1, Col2 FROM tbl WHERE @Var LIKE 'xyz'
UNION ALL
SELECT Col3, Col4 FROM tbl WHERE @Var LIKE 'zyx'
UNION ALL
SELECT Col7, Col8 FROM tbl WHERE @Var NOT LIKE 'xyz' AND @Var NOT LIKE 'zyx'
As this is a single command there are several performance benefits with regard to plan caching. Also the Query Optimiser will quickly eliminate those statements where @Var doesn't match the appropriate value without touching the storage engine.
Kingfisher is one of the best library for load image into URL.
Github URL - https://github.com/onevcat/Kingfisher
// If you want to use Activity Indicator.
imageview_pic.kf.indicatorType = .activity
imageview_pic.kf.setImage(with: URL(string: "Give your url string"))
// If you want to use custom placeholder image.
imageview_pic.kf.setImage(with: URL(string: "Give your url string"), placeholder: UIImage(named: "placeholder image name"), options: nil, progressBlock: nil, completionHandler: nil)
With API 29+ on Kotlin, I had to do
activity?.applicationContext!!
An example would be
ContextCompat.getColor(activity?.applicationContext!!, R.color.colorAccent),
If it's conciseness you're after, you might like:
prop.table(table(tips$smoker))
and then scale by 100 and round if you like. Or more like your exact output:
tbl <- table(tips$smoker)
cbind(tbl,prop.table(tbl))
If you wanted to do this for multiple columns, there are lots of different directions you could go depending on what your tastes tell you is clean looking output, but here's one option:
tblFun <- function(x){
tbl <- table(x)
res <- cbind(tbl,round(prop.table(tbl)*100,2))
colnames(res) <- c('Count','Percentage')
res
}
do.call(rbind,lapply(tips[3:6],tblFun))
Count Percentage
Female 87 35.66
Male 157 64.34
No 151 61.89
Yes 93 38.11
Fri 19 7.79

Sun 76 31.15
Thur 62 25.41
Dinner 176 72.13
Lunch 68 27.87
If you don't like stack the different tables on top of each other, you can ditch the do.call

Try to open it with pandas:

Or try any other html python parser.
That's not a proper excel file, but an html readable with excel.
One of the fundamental principles behind the original C language is that memory is composed of a sequence of bytes, and code need only care about what those bytes mean at the exact moment that they are being used. Modern C allows compilers to impose additional restrictions, but C includes--and C++ retains--the ability to decompose a pointer into a sequence of bytes, assemble any sequence of bytes containing the same values into a pointer, and then use that pointer to access the earlier object.
While that ability can be useful--or even indispensable--in some kinds of applications, a language that includes that ability will be very limited in its ability to support any kind of useful and reliable garbage collection. If a compiler doesn't know everything that has been done with the bits that made up a pointer, it will have no way of knowing whether information sufficient to reconstruct the pointer might exist somewhere in the universe. Since it would be possible for that information to be stored in ways that the computer wouldn't be able to access even if it knew about them (e.g. the bytes making up the pointer might have been shown on the screen long enough for someone to write them down on a piece of paper), it may be literally impossible for a computer to know whether a pointer could possibly be used in the future.
An interesting quirk of many garbage-collected frameworks is that an object reference not defined by the bit patterns contained therein, but by the relationship between the bits held in the object reference and other information held elsewhere. In C and C++, if the bit pattern stored in a pointer identifies an object, that bit pattern will identify that object until the object is explicitly destroyed. In a typical GC system, an object may be represented by a bit pattern 0x1234ABCD at one moment in time, but the next GC cycle might replace all references to 0x1234ABCD with references to 0x4321BABE, whereupon the object would be represented by the latter pattern. Even if one were to display the bit pattern associated with an object reference and then later read it back from the keyboard, there would be no expectation that the same bit pattern would be usable to identify the same object (or any object).
If you run the GWT compiler with the -localWorkers flag, the compiler will compile multiple permutations in parallel. This lets you use all the cores of a multi-core machine, for example -localWorkers 2 will tell the compiler to do compile two permutations in parallel. You won't get order of magnitudes differences (not everything in the compiler is parallelizable) but it is still a noticable speedup if you are compiling multiple permutations.
If you're willing to use the trunk version of GWT, you'll be able to use hosted mode for any browser (out of process hosted mode), which alleviates most of the current issues with hosted mode. That seems to be where the GWT is going - always develop with hosted mode, since compiles aren't likely to get magnitudes faster.
Using ES6 syntax, if you need a "pipeline" like process where you pass the same object through a series of functions (in my case, a HTML abstract syntax tree), you can use for...of
to call each pipe function in a given array:
const setMainElement = require("./set-main-element.js")
const cacheImages = require("./cache-images.js")
const removeElements = require("./remove-elements.js")
let htmlAst = {}
const pipeline = [
setMainElement,
cacheImages,
removeElements,
(htmlAst) => {
// Using a dynamic closure.
},
]
for (const pipe of pipeline) {
pipe(htmlAst)
}
Try this:
Write mongodb
instead of mongod
sudo service mongodb status
If it only happens on mapped drives it might be bug https://bitbucket.org/tortoisehg/thg/issue/889/cant-commit-file-over-network-share. Using UNC path instead of drive letter seems to sidestep the issue.
I want to point out that all of these solutions appear to sample without replacement. Selecting the top K rows from a random sort or joining to a table that contains unique keys in random order will yield a random sample generated without replacement.
If you want your sample to be independent, you'll need to sample with replacement. See Question 25451034 for one example of how to do this using a JOIN in a manner similar to user12861's solution. The solution is written for T-SQL, but the concept works in any SQL db.
This approach will not limit element's width when using margins in flexbox
top: 0; left: 0;
transform: translate(calc(50vw - 50%));
Also for centering it vertically
top: 0; left: 0;
transform: translate(calc(50vw - 50%), calc(50vh - 50%));
Consider this snippet of code. Modify as you see fit, or to fit your requirements. You'll need to have Imports
statements for System.IO
and System.Data.OleDb
.
Dim fi As New FileInfo("c:\foo.csv")
Dim connectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Extended Properties=Text;Data Source=" & fi.DirectoryName
Dim conn As New OleDbConnection(connectionString)
conn.Open()
'the SELECT statement is important here,
'and requires some formatting to pull dates and deal with headers with spaces.
Dim cmdSelect As New OleDbCommand("SELECT Foo, Bar, FORMAT(""SomeDate"",'YYYY/MM/DD') AS SomeDate, ""SOME MULTI WORD COL"", FROM " & fi.Name, conn)
Dim adapter1 As New OleDbDataAdapter
adapter1.SelectCommand = cmdSelect
Dim ds As New DataSet
adapter1.Fill(ds, "DATA")
myDataGridView.DataSource = ds.Tables(0).DefaultView
myDataGridView.DataBind
conn.Close()
As Marc says, you run it exactly like you would from the command line. See Creating SQL Server Agent Jobs on MSDN.
Building off of ngoozeff
's answer, if you want to make a command run completely in the background (i.e., if you want to hide its output and prevent it from being killed when you close its Terminal window), you can do this instead:
cmd="google-chrome";
"${cmd}" &>/dev/null & disown;
&>/dev/null
sets the command’s stdout
and stderr
to /dev/null
instead of inheriting them from the parent process. &
makes the shell run the command in the background. disown
removes the “current” job, last one stopped or put in the background, from under the shell’s job control.In some shells you can also use &!
instead of & disown
; they both have the same effect. Bash doesn’t support &!
, though.
Also, when putting a command inside of a variable, it's more proper to use eval "${cmd}"
rather than "${cmd}"
:
cmd="google-chrome";
eval "${cmd}" &>/dev/null & disown;
If you run this command directly in Terminal, it will show the PID of the process which the command starts. But inside of a shell script, no output will be shown.
Here's a function for it:
#!/bin/bash
# Run a command in the background.
_evalBg() {
eval "$@" &>/dev/null & disown;
}
cmd="google-chrome";
_evalBg "${cmd}";
Using deferreds like Futures
.
var sequence = Futures.sequence();
sequence
.then(function(next) {
http.get({}, next);
})
.then(function(next, res) {
res.on("data", next);
})
.then(function(next, d) {
http.get({}, next);
})
.then(function(next, res) {
...
})
If you need to pass scope along then just do something like this
.then(function(next, d) {
http.get({}, function(res) {
next(res, d);
});
})
.then(function(next, res, d) { })
...
})
Besides the box-shadow, transform and border options mentioned in other answers, WebKit browsers currently also obey -webkit-text-fill-color to set the colour of the "time elapsed" numbers, but since there is no way to set their background (which might vary with platform, e.g. inverted high-contrast modes on some operating systems), you would be advised to set -webkit-text-fill-color to the value "initial" if you've used it elsewhere and the audio element is inheriting this, otherwise some users might find those numbers unreadable.
For Excel 2010 it should be UTF-8. Instruction by MS :

"The basic document structure of a SpreadsheetML document consists of the Sheets and Sheet elements, which reference the worksheets in the Workbook. A separate XML file is created for each Worksheet. For example, the SpreadsheetML for a workbook that has two worksheets name MySheet1 and MySheet2 is located in the Workbook.xml file and is shown in the following code example.
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<workbook xmlns=http://schemas.openxmlformats.org/spreadsheetml/2006/main xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships">
<sheets>
<sheet name="MySheet1" sheetId="1" r:id="rId1" />
<sheet name="MySheet2" sheetId="2" r:id="rId2" />
</sheets>
</workbook>
The worksheet XML files contain one or more block level elements such as SheetData. sheetData represents the cell table and contains one or more Row elements. A row contains one or more Cell elements. Each cell contains a CellValue element that represents the value of the cell. For example, the SpreadsheetML for the first worksheet in a workbook, that only has the value 100 in cell A1, is located in the Sheet1.xml file and is shown in the following code example.
<?xml version="1.0" encoding="UTF-8" ?>
<worksheet xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main">

When you run

you got message that your binaries are downloaded into temporary location (e.g. The downloaded binary packages are in C:\Users\User_name\AppData\Local\Temp\RtmpC6Y8Yv\downloaded_packages ). Go there. Take binaries (zip file). Copy paste into location which you get from running the code:
.libPaths()
If libPaths shows 2 locations, then paste into second one. Load library:

String path = "C:\\Documents and Settings\\Manoj\\Desktop";
String javaPath = path.replace("\\", "/"); // Create a new variable

path = path.replace("\\", "/"); // Just use the existing variable
String
s are immutable. Once they are created, you can't change them. This means replace
returns a new String where the target("\\"

The difference between replaceAll
and replace
is that replaceAll will search for a regex, replace doesn't.
