According to the grammar in the CSP spec, you need to specify schemes as scheme:
, not just scheme
. So, you need to change the image source directive to:
img-src 'self' data:;
raw_input is your helper here. From documentation -
If the prompt argument is present, it is written to standard output without a trailing newline. The function then reads a line from input, converts it to a string (stripping a trailing newline), and returns that. When EOF is read, EOFError is raised.
So your code will basically look like this.
num_array = list()
num = raw_input("Enter how many elements you want:")
print 'Enter numbers in array: '
for i in range(int(num)):
n = raw_input("num :")
num_array.append(int(n))
print 'ARRAY: ',num_array
P.S: I have typed all this free hand. Syntax might be wrong but the methodology is correct. Also one thing to note is that, raw_input
does not do any type checking, so you need to be careful...
Please also see this Microsoft Connect report on essentially, how blummin' difficult it is to use PowerShell to run shell commands (oh, the irony).
http://connect.microsoft.com/PowerShell/feedback/details/376207/
They suggest using --%
as a way to force PowerShell to stop trying to interpret the text to the right.
For example:
MSBuild /t:Publish --% /p:TargetDatabaseName="MyDatabase";TargetConnectionString="Data Source=.\;Integrated Security=True" /p:SqlPublishProfilePath="Deploy.publish.xml" Database.sqlproj
the error i received was:
cockpit.socket: Failed to listen on sockets: Address already in use
the fix I discovered is:
in /usr/lib/systemd/system/cockpit service i changed the line :
#ExecStartPre=/usr/sbin/remotectl certificate --ensure --user=root --group=cockpit-ws --selinux-type=etc_t
to:
#ExecStartPre=/usr/sbin/remotectl certificate --ensure --user=root --group=cockpit-ws
so as you can see i took out the argument about selinux then i ran:
systemctl daemon-reload
systemctl start cockpit.service
then I browsed to:
I accepted the self-signed certificate and was able to login successfully to cockpit and use it normally.
this is all on a fedora25 machine. the 9090 port had already
been added using firewall-cmd
zlists = [[0] * i for i in range(10)]
zlists[0]
is a list of 0 zeroes, zlists[1]
is a list of 1 zero, zlists[2]
is a list of 2 zeroes, etc.
I know that is a old question, but...
You can also use this in your class:
@Autowired
private HttpServletRequest context;
And this will provide the current instance of HttpServletRequest
for you use on your method.
The Merge
method takes the values from the second table and merges them in with the first table, so the first will now hold the values from both.
If you want to preserve both of the original tables, you could copy the original first, then merge:
dtAll = dtOne.Copy();
dtAll.Merge(dtTwo);
The final
keyword has several usages in Java. It corresponds to both the sealed
and readonly
keywords in C#, depending on the context in which it is used.
To prevent subclassing (inheritance from the defined class):
Java
public final class MyFinalClass {...}
C#
public sealed class MyFinalClass {...}
Prevent overriding of a virtual
method.
Java
public class MyClass
{
public final void myFinalMethod() {...}
}
C#
public class MyClass : MyBaseClass
{
public sealed override void MyFinalMethod() {...}
}
As Joachim Sauer points out, a notable difference between the two languages here is that Java by default marks all non-static methods as virtual
, whereas C# marks them as sealed
. Hence, you only need to use the sealed
keyword in C# if you want to stop further overriding of a method that has been explicitly marked virtual
in the base class.
To only allow a variable to be assigned once:
Java
public final double pi = 3.14; // essentially a constant
C#
public readonly double pi = 3.14; // essentially a constant
As a side note, the effect of the readonly
keyword differs from that of the const
keyword in that the readonly
expression is evaluated at runtime rather than compile-time, hence allowing arbitrary expressions.
For max value, we can write sql query as
select age from table_name order by age desc limit 1
same way we can write in mongodb too.
db.getCollection('collection_name').find().sort({"age" : -1}).limit(1); //max age
db.getCollection('collection_name').find().sort({"age" : 1}).limit(1); //min age
Figuratively speaking JPA is just interface, Hibernate/TopLink - class (i.e. interface implementation).
You must have interface implementation to use interface. But you can use class through interface, i.e. Use Hibernate through JPA API or you can use implementation directly, i.e. use Hibernate directly, not through pure JPA API.
Good book about JPA is "High-Performance Java Persistence" of Vlad Mihalcea.
UPDATE some_table
SET this_column=x, that_column=y
WHERE something LIKE 'them'
To avoid update names that contain .com
like [email protected]
to [email protected]
, you can do this:
UPDATE Yourtable
SET Email = LEFT(@Email, LEN(@Email) - 4) + REPLACE(RIGHT(@Email, 4), '.com', '.org')
If you are dealing with a table and one of the dates happens to be null, you can code it like this:
@{
if (Model.SomeCollection[i].date_due == null)
{
<td><input type='date' id="@("dd" + i)" name="dd" /></td>
}
else
{
<td><input type='date' value="@Model.SomeCollection[i].date_due.Value.ToString("yyyy-MM-dd")" id="@("dd" + i)" name="dd" /></td>
}
}
You can try to turn support on in spring's converter
@EnableWebMvc
@Configuration
public class WebConfig implements WebMvcConfigurer {
@Override
public void extendMessageConverters(List<HttpMessageConverter<?>> converters) {
// add converter suport Content-Type: 'application/x-www-form-urlencoded'
converters.stream()
.filter(AllEncompassingFormHttpMessageConverter.class::isInstance)
.map(AllEncompassingFormHttpMessageConverter.class::cast)
.findFirst()
.ifPresent(converter -> converter.addSupportedMediaTypes(MediaType.APPLICATION_FORM_URLENCODED_VALUE));
}
}
equation of line is y-y1 = m(x-x1)
here m is y2-y1 / x2-x1
now put m in equation and put condition on y < m(x-x1) + y1 then it is left side point
eg.
for i in rows:
for j in cols:
if j>m(i-a)+b:
image[i][j]=0
use below inside your app.js
app.use(express.static('folderName'));
(folderName is folder which has files) - remember these assets are accessed direct through server path (i.e. http://localhost:3000/abc.png (where as abc.png is inside folderName folder)
This is an old post, but I thought I should provide an illustrated answer anyway.
Use javascript's object notation. Like so:
states_dictionary={
"CT":["alex","harry"],
"AK":["liza","alex"],
"TX":["fred", "harry"]
};
And to access the values:
states_dictionary.AK[0] //which is liza
or you can use javascript literal object notation, whereby the keys not require to be in quotes:
states_dictionary={
CT:["alex","harry"],
AK:["liza","alex"],
TX:["fred", "harry"]
};
for i in *.xls ; do
[[ -f "$i" ]] || continue
xls2csv "$i" "${i%.xls}.csv"
done
The first line in the do
checks if the "matching" file really exists, because in case nothing matches in your for
, the do
will be executed with "*.xls" as $i
. This could be horrible for your xls2csv
.
str1.toLowerCase().contains(str2.toLowerCase())
something.data()
will return a pointer to the data space of the vector.
Here is my solution
Use androidx.appcompat.app.AppCompatActivity
for the activity that contains the NavHostFragment
fragment.
Define the following interface and implement it in all navigation destination fragments
interface InterceptionInterface {
fun onNavigationUp(): Boolean
fun onBackPressed(): Boolean
}
In your activity override onSupportNavigateUp
and onBackPressed
:
override fun onSupportNavigateUp(): Boolean {
return getCurrentNavDest().onNavigationUp() || navigation_host_fragment.findNavController().navigateUp()
}
override fun onBackPressed() {
if (!getCurrentNavDest().onBackPressed()){
super.onBackPressed()
}
}
private fun getCurrentNavDest(): InterceptionInterface {
val currentFragment = navigation_host_fragment.childFragmentManager.primaryNavigationFragment as InterceptionInterface
return currentFragment
}
This solution has the advantage, that the navigation destination fragments don't need to worry about the unregistering of their listeners as soon as they are detached.
Keep it simple.
footer {
bottom: 0;
position: absolute;
}
You may need to also offset the height of the footer by adding a margin-bottom
equivalent to the footer height to the body
.
much easier use it
<input type="button" id="loadFileXml" value="Custom Button Name"onclick="document.getElementById('file').click();" />
<input type="file" style="display:none;" id="file" name="file"/>
decimal vIn = 0.0M;
int vOut = Convert.ToInt32(vIn);
Here is a very handy convert data type webpage for those of others. http://www.convertdatatypes.com/Convert-decimal-to-int-in-CSharp.html
using System.Linq;
var yourList = SomeDAO.GetRandomThings();
yourList.ToList().Sort( (thing, randomThing) => thing.CompareThisProperty.CompareTo( randomThing.CompareThisProperty ) );
That's pretty !ghetto.
Depending on what you're actually going to do with the data after it's collected, collections.defaultdict(int) might be useful.
You can use iReport editor to define the layout, and publish the report in jasper reports server. After publish you can invoke the rest api to get the results.
Here is the test of the functionality:

I wanted to add something to the answer already provided. maven-compiler-plugin by default will compile your project using Java 1.5 which is where m2e get's its information.
That's why you have to explicitly declare the maven-compiler-plugin in your project with something other then 1.5. Your effective pom.xml
will implicitly use the default set in the maven-compiler-plugin pom.xml
.
Swift 4+ approach:
1) Set UIScrollView top, bottom, left and right margins to 0
2) Inside the UIScrollView add a UIView and set top, bottom, leading, trailing margins to 0 ( equal to UIScrollView margins ).
3) The most important part is to set width and height, where height constraint should have a low priority.
private func setupConstraints() {
// Constraints for scrollView
scrollView.topAnchor.constraint(equalTo: view.topAnchor).isActive = true
scrollView.leadingAnchor.constraint(equalTo: view.leadingAnchor).isActive = true
scrollView.trailingAnchor.constraint(equalTo: view.trailingAnchor).isActive = true
scrollView.bottomAnchor.constraint(equalTo: view.bottomAnchor).isActive = true
// Constraints for containerView
containerView.topAnchor.constraint(equalTo: scrollView.topAnchor).isActive = true
containerView.bottomAnchor.constraint(equalTo: scrollView.bottomAnchor).isActive = true
containerView.leadingAnchor.constraint(equalTo: scrollView.leadingAnchor).isActive = true
containerView.trailingAnchor.constraint(equalTo: scrollView.trailingAnchor).isActive = true
containerView.widthAnchor.constraint(equalTo: scrollView.widthAnchor).isActive = true
let heightConstraint = containerView.heightAnchor.constraint(equalTo: scrollView.heightAnchor)
heightConstraint.priority = UILayoutPriority(rawValue: 250)
heightConstraint.isActive = true
}
I've changed my code like this and it works:

IF UPDATING THEN

@RequestParam
annotation tells Spring that it should map a request parameter from the GET/POST request to your method argument. For example:
request:
GET: http://someserver.org/path?name=John&surname=Smith
endpoint code:
public User getUser(@RequestParam(value = "name") String name,
@RequestParam(value = "surname") String surname){
...
}
So basically, while @RequestBody
maps entire user request (even for POST) to a String variable, @RequestParam
does so with one (or more - but it is more complicated) request param to your method argument.
Make a list(your_string).
>>> s = "mep"
>>> list(s)
['m', 'e', 'p']
If you need to take two integers say a,b in python you can use map function.
Suppose input is,
1 5 3 1 2 3 4 5
where 1 represent test case, 5 represent number of values and 3 represents a task value and in next line given 5 values, we can take such input using this method in PYTH 2.x Version.
testCases=int(raw_input())
number, taskValue = map(int, raw_input().split())
array = map(int, raw_input().split())
You can replace 'int' in map() with another datatype needed.
You can also use matches with regular expression like this:
boolean bool = List.matches("(?i).*SOME STRING HERE.*")
ImageIcon image = new ImageIcon("image/pic1.jpg");
JLabel label = new JLabel("", image, JLabel.CENTER);
JPanel panel = new JPanel(new BorderLayout());
panel.add( label, BorderLayout.CENTER );
@Martin Konecny's answer provides the correct answer, but - as he mentions - it only works if the actual script is not invoked through a symlink residing in a different directory.
This answer covers that case: a solution that also works when the script is invoked through a symlink or even a chain of symlinks:
Linux / GNU readlink
solution:
If your script needs to run on Linux only or you know that GNU readlink
is in the $PATH
, use readlink -f
, which conveniently resolves a symlink to its ultimate target:
scriptDir=$(dirname -- "$(readlink -f -- "$BASH_SOURCE")")
Note that GNU readlink
has 3 related options for resolving a symlink to its ultimate target's full path: -f
(--canonicalize
), -e
(--canonicalize-existing
), and -m
(--canonicalize-missing
) - see man readlink
.
Since the target by definition exists in this scenario, any of the 3 options can be used; I've chosen -f
here, because it is the most well-known one.
Multi-(Unix-like-)platform solution (including platforms with a POSIX-only set of utilities):
If your script must run on any platform that:
has a readlink
utility, but lacks the -f
option (in the GNU sense of resolving a symlink to its ultimate target) - e.g., macOS.
readlink
; note that recent versions of FreeBSD/PC-BSD do support -f
.does not even have readlink
, but has POSIX-compatible utilities - e.g., HP-UX (thanks, @Charles Duffy).
The following solution, inspired by https://stackoverflow.com/a/1116890/45375,
defines helper shell function, rreadlink()
, which resolves a given symlink to its ultimate target in a loop - this function is in effect a POSIX-compliant implementation of GNU readlink
's -e
option, which is similar to the -f
option, except that the ultimate target must exist.
Note: The function is a bash
function, and is POSIX-compliant only in the sense that only POSIX utilities with POSIX-compliant options are used. For a version of this function that is itself written in POSIX-compliant shell code (for /bin/sh
), see here.
If readlink
is available, it is used (without options) - true on most modern platforms.
Otherwise, the output from ls -l
is parsed, which is the only POSIX-compliant way to determine a symlink's target.
Caveat: this will break if a filename or path contains the literal substring ->
- which is unlikely, however.
(Note that platforms that lack readlink
may still provide other, non-POSIX methods for resolving a symlink; e.g., @Charles Duffy mentions HP-UX's find
utility supporting the %l
format char. with its -printf
primary; in the interest of brevity the function does NOT try to detect such cases.)
An installable utility (script) form of the function below (with additional functionality) can be found as rreadlink
in the npm registry; on Linux and macOS, install it with [sudo] npm install -g rreadlink
; on other platforms (assuming they have bash
), follow the manual installation instructions.
If the argument is a symlink, the ultimate target's canonical path is returned; otherwise, the argument's own canonical path is returned.

JSON, like xml and various other formats, is a tree-based serialization format. It won't love you if you have circular references in your objects, as the "tree" would be:
root B => child A => parent B => child A => parent B => ...
There are often ways of disabling navigation along a certain path; for example, with XmlSerializer
you might mark the parent property as XmlIgnore
. I don't know if this is possible with the json serializer in question, nor whether DatabaseColumn
has suitable markers (very unlikely, as it would need to reference every serialization API)
Have you tried not setting the responseType and just type casting the response?
This is what worked for me:
/**
* Client for consuming recordings HTTP API endpoint.
*/
@Injectable({
providedIn: 'root'
})
export class DownloadUrlClientService {
private _log = Log.create('DownloadUrlClientService');
constructor(
private _http: HttpClient,
) {}
private async _getUrl(url: string): Promise<string> {
const httpOptions = {headers: new HttpHeaders({'auth': 'false'})};
// const httpOptions = {headers: new HttpHeaders({'auth': 'false'}), responseType: 'text'};
const res = await (this._http.get(url, httpOptions) as Observable<string>).toPromise();
// const res = await (this._http.get(url, httpOptions)).toPromise();
return res;
}
}
XAMPP should have come with a "fake" sendmail program. In that case, you can use sendmail as well:

;sendmail_from = [email protected]
; For Unix only. You may supply arguments as well (default: "sendmail -t -i").
; http://php.net/sendmail-path
sendmail_path = "C:/xampp/sendmail/sendmail.exe -t -i"
Sendmail should have a sendmail.ini
with it; it should be configured as so:
# Example for a user configuration file
# Set default values for all following accounts.
defaults
logfile "C:\xampp\sendmail\sendmail.log"
# Mercury
#account Mercury
#host localhost
#from postmaster@localhost
#auth off
# A freemail service example
account ACCOUNTNAME_HERE
tls on
tls_certcheck off
host smtp.gmail.com
from EMAIL_HERE
auth on
user EMAIL_HERE
password PASSWORD_HERE
# Set a default account
account default : ACCOUNTNAME_HERE
Of course, replace ACCOUNTNAME_HERE with an arbitrary account name, replace EMAIL_HERE with a valid email (such as a Gmail or Hotmail), and replace PASSWORD_HERE with the password to your email. Now, you should be able to send mail. Remember to restart Apache (from the control panel or the batch files) to allow the changes to PHP to work.
I've personally always found the csv module kind of annoying. I expect someone else will show you how to do this slickly with it, but my quick and dirty solution is:
with open('dict.csv', 'w') as f: # This creates the file object for the context
# below it and closes the file automatically
l = []
for k, v in mydict.iteritems(): # Iterate over items returning key, value tuples
l.append('%s: %s' % (str(k), str(v))) # Build a nice list of strings
f.write(', '.join(l)) # Join that list of strings and write out
However, if you want to read it back in, you'll need to do some irritating parsing, especially if it's all on one line. Here's an example using your proposed file format.
with open('dict.csv', 'r') as f: # Again temporary file for reading
d = {}
l = f.read().split(',') # Split using commas
for i in l:
values = i.split(': ') # Split using ': '
d[values[0]] = values[1] # Any type conversion will need to happen here
you can use:
adb shell su -c "your command here"
only rooted devices with su works.
Use itertools.product!
from itertools import product
for x, y in product(range(10), range(10)):
#do whatever you want
break
Here's a link to itertools.product in the python documentation: http://docs.python.org/library/itertools.html#itertools.product
You can also loop over an array comprehension with 2 fors in it, and break whenever you want to.
>>> [(x, y) for y in ['y1', 'y2'] for x in ['x1', 'x2']]
[
('x1', 'y1'), ('x2', 'y1'),
('x1', 'y2'), ('x2', 'y2')
]
If you want to parse using InputStreams
public Object xmlToObject(String xmlDataString) {
Object converted = null;
try {
JAXBContext jc = JAXBContext.newInstance(Response.class);
Unmarshaller unmarshaller = jc.createUnmarshaller();
InputStream stream = new ByteArrayInputStream(xmlDataString.getBytes(StandardCharsets.UTF_8));
converted = unmarshaller.unmarshal(stream);
} catch (JAXBException e) {
e.printStackTrace();
}
return converted;
}
In Notepad++ go to Plugins > Plugin manager > Show Plugin Manager
then find Xml Tools
plugin. Tick the box and click Install
Open XML document you want to validate and click Ctrl+Shift+Alt+M (Or use Menu if this is your preference Plugins > XML Tools > Validate Now
).
Following dialog will open:
Click on ...
. Point to XSD file and I am pretty sure you'll be able to handle things from here.
Hope this saves you some time.
EDIT:
Plugin manager was not included in some versions of Notepad++ because many users didn't like commercials that it used to show. If you want to keep an older version, however still want plugin manager, you can get it on github, and install it by extracting the archive and copying contents to plugins and updates folder.
In version 7.7.1
plugin manager is back under a different guise... Plugin Admin
so now you can simply update notepad++ and have it back.

This is my Windows Batch version for update all plugins in one command
How to use:
From command line, in the same folder of project, run
c:\> batchNameFile
or
c:\> batchNameFile autoupdate
Where "batchNameFile" is the name of .BAT file, with the script below.
For only test ( first exmple ) or to force every update avaiable ( 2nd example )
@echo off
cls
set pluginListFile=update.plugin.list
if exist %pluginListFile% del %pluginListFile%
Echo "Reading installed Plugins"
Call cordova plugins > %pluginListFile%
echo.
for /F "tokens=1,2 delims= " %%a in ( %pluginListFile% ) do (
Echo "Checking online version for %%a"
for /F "delims=" %%I in ( 'npm info %%a version' ) do (
Echo "Local : %%b"
Echo "Online: %%I"
if %%b LSS %%I Call :toUpdate %%a %~1
:cont
echo.
)
)
if exist %pluginListFile% del %pluginListFile%
Exit /B
:toUpdate
Echo "Need Update !"
if '%~2' == 'autoupdate' Call :DoUpdate %~1
goto cont
:DoUpdate
Echo "Removing Plugin"
Call cordova plugin rm %~1
Echo "Adding Plugin"
Call cordova plugin add %~1
goto cont

As @Devart says, the total length of your index is too long.
The short answer is that you shouldn't be indexing such long VARCHAR columns anyway, because the index will be very bulky and inefficient.
The best practice is to use prefix indexes so you're only indexing a left substring of the data. Most of your data will be a lot shorter than 255 characters anyway.
You can declare a prefix length per column as you define the index. For example:
...
KEY `index` (`parent_menu_id`,`menu_link`(50),`plugin`(50),`alias`(50))
...
But what's the best prefix length for a given column? Here's a method to find out:
SELECT
ROUND(SUM(LENGTH(`menu_link`)<10)*100/COUNT(`menu_link`),2) AS pct_length_10,
ROUND(SUM(LENGTH(`menu_link`)<20)*100/COUNT(`menu_link`),2) AS pct_length_20,
ROUND(SUM(LENGTH(`menu_link`)<50)*100/COUNT(`menu_link`),2) AS pct_length_50,
ROUND(SUM(LENGTH(`menu_link`)<100)*100/COUNT(`menu_link`),2) AS pct_length_100
FROM `pds_core_menu_items`;
It tells you the proportion of rows that have no more than a given string length in the menu_link
column. You might see output like this:
+---------------+---------------+---------------+----------------+
| pct_length_10 | pct_length_20 | pct_length_50 | pct_length_100 |
+---------------+---------------+---------------+----------------+
| 21.78 | 80.20 | 100.00 | 100.00 |
+---------------+---------------+---------------+----------------+
This tells you that 80% of your strings are less than 20 characters, and all of your strings are less than 50 characters. So there's no need to index more than a prefix length of 50, and certainly no need to index the full length of 255 characters.
PS: The INT(1)
and INT(32)
data types indicates another misunderstanding about MySQL. The numeric argument has no effect related to storage or the range of values allowed for the column. INT
is always 4 bytes, and it always allows values from -2147483648 to 2147483647. The numeric argument is about padding values during display, which has no effect unless you use the ZEROFILL
option.
You could also do something as follow
public enum DAY {MON, TUES, WED, THU, FRI, SAT, SUN};
EnumSet.allOf(DAY.class).stream().map(e -> e.name()).collect(Collectors.toList())
or
EnumSet.allOf(DAY.class).stream().map(DAY::name).collect(Collectors.toList())
The main reason why I stumbled across this question is that I wanted to write a generic validator that validates whether a given string enum name is valid for a given enum type (Sharing in case anyone finds useful).
For the validation, I had to use Apache's EnumUtils
library since the type of enum is not known at compile time.
@SuppressWarnings({ "unchecked", "rawtypes" })
public static void isValidEnumsValid(Class clazz, Set<String> enumNames) {
Set<String> notAllowedNames = enumNames.stream()
.filter(enumName -> !EnumUtils.isValidEnum(clazz, enumName))
.collect(Collectors.toSet());
if (notAllowedNames.size() > 0) {
String validEnumNames = (String) EnumUtils.getEnumMap(clazz).keySet().stream()
.collect(Collectors.joining(", "));
throw new IllegalArgumentException("The requested values '" + notAllowedNames.stream()
.collect(Collectors.joining(",")) + "' are not valid. Please select one more (case-sensitive) "
+ "of the following : " + validEnumNames);
}
}
I was too lazy to write an enum annotation validator as shown in here https://stackoverflow.com/a/51109419/1225551
According to this posting by the lead Jenkins developer, Kohsuke Kawaguchi, in 2009, there is no group support for the built-in Jenkins user database. Group support is only usable when integrating Jenkins with LDAP or Active Directory. This appears to be the same in 2012.
However, as Vadim wrote in his answer, you don't need group support for the built-in Jenkins user database, thanks to the Role strategy plug-in.
For local access, large numbers of directories/files doesn't seem to be an issue. However, if you're accessing it across a network, there's a noticeable performance hit after a few hundred (especially when accessed from Vista machines (XP to Windows Server w/NTFS seemed to run much faster in that regard)).
String[] is an array of Strings. Such an array is internally a class. Like all classes that don't explicitly extend some other class, it extends Object implicitly. The method toString()
of class Object, by default, gives you the representation you see: the class name, followed by @, followed by the hash code in hex. Since the String[] class doesn't override the toString() method, you get that as a result.
Create some method that outputs the array elements for you. Iterate over the array and use System.out.print()
(not print*ln*) on the elements.
So, @Vivek has got the solution to the problem through a dialogue in the Comments rather than through an actual answer.

I use another dirty trick that is aufs/devicemapper agnostic.
I look at the command that the container is running e.g. docker ps
and if it's an apache or java
i just do the following:
sudo -s
cd /proc/$(pgrep java)/root/
and voilá you're inside the container.
Basically you can as root cd into /proc/<PID>/root/
folder as long as that process is run by the container. Beware symlinks will not make sense wile using that mode.
In order to perform chmod, you need to be owner of the file you are trying to modify, or the root user.
Yes, this is a kind of inconsistency in the language.
The "=" in myarray = "abc";
is assignment (which won't work as the array is basically a kind of constant pointer), whereas in char myarray[4] = "abc";
it's an initialization of the array. There's no way for "late initialization".
You should just remember this rule.
You can use strftime
to convert datetimes to any character format:
> t <- strftime(times, format="%H:%M:%S")
> t
[1] "02:06:49" "03:37:07" "00:22:45" "00:24:35" "03:09:57" "03:10:41"
[7] "05:05:57" "07:39:39" "06:47:56" "07:56:36"
But that doesn't help very much, since you want to plot your data. One workaround is to strip the date element from your times, and then to add an identical date to all of your times:
> xx <- as.POSIXct(t, format="%H:%M:%S")
> xx
[1] "2012-03-23 02:06:49 GMT" "2012-03-23 03:37:07 GMT"
[3] "2012-03-23 00:22:45 GMT" "2012-03-23 00:24:35 GMT"
[5] "2012-03-23 03:09:57 GMT" "2012-03-23 03:10:41 GMT"
[7] "2012-03-23 05:05:57 GMT" "2012-03-23 07:39:39 GMT"
[9] "2012-03-23 06:47:56 GMT" "2012-03-23 07:56:36 GMT"
Now you can use these datetime
objects in your plot:
plot(xx, rnorm(length(xx)), xlab="Time", ylab="Random value")

The modern way is AuthenticationHandlers
in startup.cs add
services.AddAuthentication("BasicAuthentication").AddScheme<AuthenticationSchemeOptions, BasicAuthenticationHandler>("BasicAuthentication", null);
public class BasicAuthenticationHandler : AuthenticationHandler<AuthenticationSchemeOptions>
{
private readonly IUserService _userService;
public BasicAuthenticationHandler(
IOptionsMonitor<AuthenticationSchemeOptions> options,
ILoggerFactory logger,
UrlEncoder encoder,
ISystemClock clock,
IUserService userService)
: base(options, logger, encoder, clock)
{
_userService = userService;
}
protected override async Task<AuthenticateResult> HandleAuthenticateAsync()
{
if (!Request.Headers.ContainsKey("Authorization"))
return AuthenticateResult.Fail("Missing Authorization Header");
User user = null;
try
{
var authHeader = AuthenticationHeaderValue.Parse(Request.Headers["Authorization"]);
var credentialBytes = Convert.FromBase64String(authHeader.Parameter);
var credentials = Encoding.UTF8.GetString(credentialBytes).Split(new[] { ':' }, 2);
var username = credentials[0];
var password = credentials[1];
user = await _userService.Authenticate(username, password);
}
catch
{
return AuthenticateResult.Fail("Invalid Authorization Header");
}
if (user == null)
return AuthenticateResult.Fail("Invalid User-name or Password");
var claims = new[] {
new Claim(ClaimTypes.NameIdentifier, user.Id.ToString()),
new Claim(ClaimTypes.Name, user.Username),
};
var identity = new ClaimsIdentity(claims, Scheme.Name);
var principal = new ClaimsPrincipal(identity);
var ticket = new AuthenticationTicket(principal, Scheme.Name);
return AuthenticateResult.Success(ticket);
}
}
IUserService is a service that you make where you have user name and password. basically it returns a user class that you use to map your claims on.
var claims = new[] {
new Claim(ClaimTypes.NameIdentifier, user.Id.ToString()),
new Claim(ClaimTypes.Name, user.Username),
};
Then you can query these claims and her any data you mapped, ther are quite a few, have a look at ClaimTypes class
you can use this in an extension method an get any of the mappings
public int? GetUserId()
{
if (context.User.Identity.IsAuthenticated)
{
var id=context.User.FindFirst(ClaimTypes.NameIdentifier);
if (!(id is null) && int.TryParse(id.Value, out var userId))
return userId;
}
return new Nullable<int>();
}
This new way, i think is better than the old way as shown here, both work
public class BasicAuthenticationAttribute : AuthorizationFilterAttribute
{
public override void OnAuthorization(HttpActionContext actionContext)
{
if (actionContext.Request.Headers.Authorization != null)
{
var authToken = actionContext.Request.Headers.Authorization.Parameter;
// decoding authToken we get decode value in 'Username:Password' format
var decodeauthToken = System.Text.Encoding.UTF8.GetString(Convert.FromBase64String(authToken));
// spliting decodeauthToken using ':'
var arrUserNameandPassword = decodeauthToken.Split(':');
// at 0th postion of array we get username and at 1st we get password
if (IsAuthorizedUser(arrUserNameandPassword[0], arrUserNameandPassword[1]))
{
// setting current principle
Thread.CurrentPrincipal = new GenericPrincipal(new GenericIdentity(arrUserNameandPassword[0]), null);
}
else
{
actionContext.Response = actionContext.Request.CreateResponse(HttpStatusCode.Unauthorized);
}
}
else
{
actionContext.Response = actionContext.Request.CreateResponse(HttpStatusCode.Unauthorized);
}
}
public static bool IsAuthorizedUser(string Username, string Password)
{
// In this method we can handle our database logic here...
return Username.Equals("test") && Password == "test";
}
}
1) You can use the !important
rule, like this:
.selected
{
background-color:red !important;
}
See http://www.w3.org/TR/CSS2/cascade.html#important-rules for more info.
2) In your example you can also get the red background by using ul.nav li.selected
instead of just .selected
. This makes the selector more specific.
See http://www.w3.org/TR/CSS2/cascade.html#specificity for more info.
int &z = 12;
On the right hand side, a temporary object of type int
is created from the integral literal 12
, but the temporary cannot be bound to non-const reference. Hence the error. It is same as:
int &z = int(12); //still same error
Why a temporary gets created? Because a reference has to refer to an object in the memory, and for an object to exist, it has to be created first. Since the object is unnamed, it is a temporary object. It has no name. From this explanation, it became pretty much clear why the second case is fine.
A temporary object can be bound to const reference, which means, you can do this:
const int &z = 12; //ok
For the sake of the completeness, I would like to add that C++11 has introduced rvalue-reference, which can bind to temporary object. So in C++11, you can write this:
int && z = 12; //C+11 only
Note that there is &&
intead of &
. Also note that const
is not needed anymore, even though the object which z
binds to is a temporary object created out of integral-literal 12
.
Since C++11 has introduced rvalue-reference, int&
is now henceforth called lvalue-reference.
Move all of your state and your handleClick
function from Header
to your MainWrapper
component.
Then pass values as props to all components that need to share this functionality.
class MainWrapper extends React.Component {
constructor() {
super();
this.state = {
sidbarPushCollapsed: false,
profileCollapsed: false
};
this.handleClick = this.handleClick.bind(this);
}
handleClick() {
this.setState({
sidbarPushCollapsed: !this.state.sidbarPushCollapsed,
profileCollapsed: !this.state.profileCollapsed
});
}
render() {
return (
//...
<Header
handleClick={this.handleClick}
sidbarPushCollapsed={this.state.sidbarPushCollapsed}
profileCollapsed={this.state.profileCollapsed} />
);
Then in your Header's render() method, you'd use this.props
:
<button type="button" id="sidbarPush" onClick={this.props.handleClick} profile={this.props.profileCollapsed}>
I noticed that whilst the other answers explained what require is and that it is used to load modules in Node they did not give a full reply on how to load node modules when working in the Browser.
It is quite simple to do. Install your module using npm as you describe, and the module itself will be located in a folder usually called node_modules.
Now the simplest way to load it into your app is to reference it from your html with a script tag which points at this directory. i.e if your node_modules directory is in the root of the project at the same level as your index.html you would write this in your index.html:
<script src="node_modules/ng"></script>
That whole script will now be loaded into the page - so you can access its variables and methods directly.
There are other approaches which are more widely used in larger projects, such as a module loader like require.js. Of the two, I have not used Require myself, but I think it is considered by many people the way to go.

Use getattr
to get an attribute from a name in a string. In other words, get the instance as
instance = getattr(modul, class_name)()
Do not use the ToList()
method as in the accepted answer !
Running SQL profiler, I verified and found that ToList()
function gets all the records from the database. It is really bad performance !!
I would have run this query by pure sql command as follows:
string query = "Update YourTable Set ... Where ...";
context.Database.ExecuteSqlCommandAsync(query, new SqlParameter("@ColumnY", value1), new SqlParameter("@ColumnZ", value2));
This would operate the update in one-shot without selecting even one row.
As @Jared Ng and @Issun pointed out, the key to solve this kind of RegEx like "matching everything up to a certain word or substring" or "matching everything after a certain word or substring" is called "lookaround" zero-length assertions. Read more about them here.
In your particular case, it can be solved by a positive look ahead: .+?(?=abc)
A picture is worth a thousand words. See the detail explanation in the screenshot.
I changed the hide/show event trigger from Catalint based on Glenns idea. My problem was that I have a modular application. I change between modules showing and hiding divs parents. Then when I hide a module and show another one, with his method I have a visible delay when I change between modules. I only need sometimes to liten this event, and in some special childs. So I decided to notify only the childs with the class "displayObserver"
$.each(["show", "hide", "toggleClass", "addClass", "removeClass"], function () {
var _oldFn = $.fn[this];
$.fn[this] = function () {
var hidden = this.find(".displayObserver:hidden").add(this.filter(":hidden"));
var visible = this.find(".displayObserver:visible").add(this.filter(":visible"));
var result = _oldFn.apply(this, arguments);
hidden.filter(":visible").each(function () {
$(this).triggerHandler("show");
});
visible.filter(":hidden").each(function () {
$(this).triggerHandler("hide");
});
return result;
}
});
Then when a child wants to listen for "show" or "hide" event I have to add him the class "displayObserver", and when It does not want to continue listen it, I remove him the class
bindDisplayEvent: function () {
$("#child1").addClass("displayObserver");
$("#child1").off("show", this.onParentShow);
$("#child1").on("show", this.onParentShow);
},
bindDisplayEvent: function () {
$("#child1").removeClass("displayObserver");
$("#child1").off("show", this.onParentShow);
},

You can do it using javascript. Grab the value of the form field in your submit function, parse out the extension.
You can start with something like this:
<form name="someform"enctype="multipart/form-data" action="uploader.php" method="POST">
<input type=file name="file1" />
<input type=button onclick="val()" value="xxxx" />
</form>
<script>
function val() {
alert(document.someform.file1.value)
}
</script>
I agree with alexmac - do it server-side as well.
Iterators are first choice over operator[]
. C++11 provides std::begin()
, std::end()
functions.
As your code uses just std::vector
, I can't say there is much difference in both codes, however, operator []
may not operate as you intend to. For example if you use map, operator[]
will insert an element if not found.
Also, by using iterator
your code becomes more portable between containers. You can switch containers from std::vector
to std::list
or other container freely without changing much if you use iterator such rule doesn't apply to operator[]

We can use elasticdump to take the backup and restore it, We can move data from one server/cluster to another server/cluster.
1. Commands to move one index data from one server/cluster to another using elasticdump
.
# Copy an index from production to staging with analyzer and mapping:
elasticdump \
--input=http://production.es.com:9200/my_index \
--output=http://staging.es.com:9200/my_index \
--type=analyzer
elasticdump \
--input=http://production.es.com:9200/my_index \
--output=http://staging.es.com:9200/my_index \
--type=mapping
elasticdump \
--input=http://production.es.com:9200/my_index \
--output=http://staging.es.com:9200/my_index \
--type=data
2. Commands to move all indices data from one server/cluster to another using multielasticdump
.
Backup
multielasticdump \
--direction=dump \
--match='^.*$' \
--limit=10000 \
--input=http://production.es.com:9200 \
--output=/tmp
Restore
multielasticdump \
--direction=load \
--match='^.*$' \
--limit=10000 \
--input=/tmp \
--output=http://staging.es.com:9200
Note:
If the --direction is dump, which is the default, --input MUST be a URL for the base location of an ElasticSearch server (i.e. http://localhost:9200) and --output MUST be a directory. Each index that does match will have a data, mapping, and analyzer file created.
For loading files that you have dumped from multi-elasticsearch, --direction should be set to load, --input MUST be a directory of a multielasticsearch dump and --output MUST be a Elasticsearch server URL.
The 2nd command will take a backup of settings
, mappings
, template
and data
itself as JSON files.
The --limit
should not be more than 10000
otherwise, it will give an exception.
Try the following code:
public static byte[] decode(String hex){
String[] list=hex.split("(?<=\\G.{2})");
ByteBuffer buffer= ByteBuffer.allocate(list.length);
System.out.println(list.length);
for(String str: list)
buffer.put(Byte.parseByte(str,16));
return buffer.array();
}
To convert to String just create a new String with the byte[] returned by the decode method.
use if var is null
We can use pattern to validate it.
android.util.Patterns.PHONE
public class GeneralUtils {
private static boolean isValidPhoneNumber(String phoneNumber) {
return !TextUtils.isEmpty(phoneNumber) && android.util.Patterns.PHONE.matcher(phoneNumber).matches();
}
}
I consider this simpler than any prior correct answer. I'll also throw in javadoc. :-)
/**
* Converts the given string to title case, where the first
* letter is capitalized and the rest of the string is in
* lower case.
*
* @param s a string with unknown capitalization
* @return a title-case version of the string
*/
public static String toTitleCase(String s)
{
if (s.isEmpty())
{
return s;
}
return s.substring(0, 1).toUpperCase() + s.substring(1).toLowerCase();
}
Strings of length 1 do not needed to be treated as a special case because s.substring(1)
returns the empty string when s
has length 1.
No, there is not.
First of all, SQL injection is an input filtering problem, and XSS is an output escaping one - so you wouldn't even execute these two operations at the same time in the code lifecycle.
Basic rules of thumb
mysql_real_escape_string()
)strip_tags()
to filter out unwanted HTMLhtmlspecialchars()
and be mindful of the 2nd and 3rd parameters here.Perhaps the easiest is to use position: absolute
to fix to the bottom, then a suitable margin/padding to make sure that the other text doesn't spill over the top of it.
css:
<style>
body {
margin: 0 0 20px;
}
.footer {
position: absolute;
bottom: 0;
height: 20px;
background: #f0f0f0;
width: 100%;
}
</style>
Here is the html main content.
<div class="footer"> Here is the footer. </div>
Upgrading to tomcat 7.0.70 resolved the issue for me
Short story: The 0
tells the parser it's dealing with a constant (and not an identifier/reserved word). Something is still needed to specify the number base: the x
is an arbitrary choice.
Long story: In the 60's, the prevalent programming number systems were decimal and octal — mainframes had 12, 24 or 36 bits per byte, which is nicely divisible by 3 = log2(8).
The BCPL language used the syntax 8 1234
for octal numbers. When Ken Thompson created B from BCPL, he used the 0
prefix instead. This is great because
0
is the same in both bases),00005 == 05
), and#123
).When C was created from B, the need for hexadecimal numbers arose (the PDP-11 had 16-bit words) and all of the points above were still valid. Since octals were still needed for other machines, 0x
was arbitrarily chosen (00
was probably ruled out as awkward).
C# is a descendant of C, so it inherits the syntax.
If we directly take the binary distribution of Apache Hadoop 2.2.0 release and try to run it on Microsoft Windows, then we'll encounter ERROR util.Shell: Failed to locate the winutils binary in the hadoop binary path.
The binary distribution of Apache Hadoop 2.2.0 release does not contain some windows native components (like winutils.exe, hadoop.dll etc). These are required (not optional) to run Hadoop on Windows.
So you need to build windows native binary distribution of hadoop from source codes following "BUILD.txt" file located inside the source distribution of hadoop. You can follow the following posts as well for step by step guide with screen shot
Build, Install, Configure and Run Apache Hadoop 2.2.0 in Microsoft Windows OS

If you are using Any CPU
you may need to put it in single quotes.
Certainly when running in a Dockerfile, I had to use single quotes:
# Fails. Gives: MSBUILD : error MSB1008: Only one project can be specified.
RUN msbuild ConsoleAppFw451.sln /p:Configuration=Debug /p:Platform="Any CPU"
# Passes. Gives: Successfully built 40163c3e0121
RUN msbuild ConsoleAppFw451.sln /p:Configuration=Debug /p:Platform='Any CPU'
test -z
returns true if the parameter is empty (see man sh
or man test
).
You are just adding a header which server does not allow.
eg - your server is set up CORS to allow these headers only (accept,cache-control,pragma,content-type,origin)
and in your http request you are adding like this
headers: {
'Authorization': 'Basic d2VudHdvcnRobWFuOkNoYW5nZV9tZQ==',
'Accept': 'application/json',
'x-testing': 'testingValue'
}
then the Server will reject this request since (Authorization and x-testing) are not allowed.
This is server side configuration.
And there is nothing to do with HTTP Options, it is just a preflight to server which is from different domain to check if server will allow actual call or not.
The default value can be followed with a :
after the property key, e.g.
<property name="port" value="${my.server.port:8080}" />
Or in java code:
@Value("${my.server.port:8080}")
private String myServerPort;

The cause of your problem is simple. So many people will run into the same problem, Because I did too and it took me hour to figure out. Just in case, someone else stumbles, The problem is in your query, your select statement is calling $dbname
instead of table name. So its not found whereby returning false
which is boolean
. Good luck.
Determining of root cause is not an issue since Go 1.8; field name now is shown in the error message:
json: cannot unmarshal object into Go struct field Comment.author of type string
You can use this to copy directory overwriting existing files:
import shutil
shutil.copytree("src", "dst", dirs_exist_ok=True)
dirs_exist_ok
argument was added in Python 3.8.
See docs: https://docs.python.org/3/library/shutil.html#shutil.copytree
You could also add the external jar file to the project. Go to your project-->properties-->java build path-->libraries, add external JARS. Then add your downloaded jar file.
int count = -1;
String[] content = new String[200];
while(inFile1.hasNext()){
content[++count] = inFile1.nextLine();
}
EDIT
Looks like you want to create a float array, for that create a float array
int count = -1;
Float[] content = new Float[200];
while(inFile1.hasNext()){
content[++count] = Float.parseFloat(inFile1.nextLine());
}
then your float array would look like
content[0] = 70.3
content[1] = 70.8
content[2] = 73.8
content[3] = 77.0 and so on
// replaced text will be in buffer.
void Replace(char* buffer, const char* source, const char* oldStr, const char* newStr)

if(buffer==NULL || source == NULL || oldStr == NULL || newStr == NULL) return;
int slen = strlen(source);
int olen = strlen(oldStr);
int nlen = strlen(newStr);
if(olen>slen) return;
int ix=0;
for(int i=0;i<slen;i++)
{
if(oldStr[0] == source[i])
{
bool found = true;
for(int j=1;j<olen;j++)
{
if(source[i+j]!=oldStr[j])
{
found = false;
break;
}
}
if(found)
{
for(int j=0;j<nlen;j++)
buffer[ix++] = newStr[j];
i+=(olen-1);
}
else
{
buffer[ix++] = source[i];
}
}
else
{
buffer[ix++] = source[i];
}
}
}

Your class Delivery
has no access modifier, which means it defaults to internal
. If you then try to expose a property of that type as public
, it won't work. Your type (class) needs to have the same, or higher access as your property.

What's happening when a members inside a class
is declared as static
..? That members can be accessed without instantiating the class
. Therefore making outer class(top level class) static
has no meaning. Therefore it is not allowed.
But you can set inner classes as static (As it is a member of the top level class). Then that class can be accessed without instantiating the top level class. Consider the following example.
public class A {
public static class B {
}
}
Now, inside a different class C
, class B
can be accessed without making an instance of class A
.
public class C {
A.B ab = new A.B();
}
static
classes can have non-static
members too. Only the class gets static.
But if the static
keyword is removed from class B
, it cannot be accessed directly without making an instance of A
.
public class C {
A a = new A();
A.B ab = a. new B();
}
But we cannot have static
members inside a non-static
inner class.
You need to use an Angular form directive on the select
. You can do that with ngModel
. For example
@Component({
selector: 'my-app',
template: `
<h2>Select demo</h2>
<select [(ngModel)]="selectedCity" (ngModelChange)="onChange($event)" >
<option *ngFor="let c of cities" [ngValue]="c"> {{c.name}} </option>
</select>
`
})
class App {
cities = [{'name': 'SF'}, {'name': 'NYC'}, {'name': 'Buffalo'}];
selectedCity = this.cities[1];
onChange(city) {
alert(city.name);
}
}
The (ngModelChange)
event listener emits events when the selected value changes. This is where you can hookup your callback.
Note you will need to make sure you have imported the FormsModule
into the application.
Here is a Plunker
I don't think any of these answers meet my need, unless I am fundamentally misunderstanding something.
I have an app (originally an iPad app) that I want to run both on an iPad and on the Mac, under Catalyst. I'm using the plist option to scale the Mac interface to match the iPad, but would like to migrate to AppKit if that is reasonable. When running on a Mac, I believe that all of the aforementioned approaches tell me that I'm on an iPad. The Catalyst fake-out is pretty thorough.
For most concerns I indeed understand that the code should pretend it's on an iPad when thus running on a Mac. One exception is that the rolling picker is not available on the Mac under Catalyst, but is on the iPad. I want to figure out whether to create a UIPickerView or to do something different, at run time. Run-time selection is crucial because I want to use a single binary to run both on the iPad and Mac in the long term, while making the best use of the supported UI standards on each.
The APIs give potentially misleading results to the casual pre-Catalyst reader. For example, [UIDevice currentDevice].model
returns @"iPad"
when running under Catalyst on a Mac. The user interface idiom APIs sustain the same illusion.
I found that you really need to look deeper. I start with this information:
NSString *const deviceModel = [UIDevice currentDevice].model;
NSProcessInfo *const processInfo = [[NSProcessInfo alloc] init];
const bool isIosAppOnMac = processInfo.iOSAppOnMac; // Note: this will be "no" under Catalyst
const bool isCatalystApp = processInfo.macCatalystApp;
Then you can combine these queries with expressions like [deviceModel hasPrefix: @"iPad"]
to sort out the kinds of subtleties I'm facing. For my case, I explicitly want to avoid making a UIPickerView if the indicated isCatalystApp
is true
, independent of "misleading" information about the interface idiom, or the illusions sustained by isIosAppOnMac
and deviceModel
.
Now I'm curious what happens if I move the Mac app to run over on my iPad sidecar...
The array decays to a pointer when passed.
Section 6.4 of the C FAQ covers this very well and provides the K&R references etc.
That aside, imagine it were possible for the function to know the size of the memory allocated in a pointer. You could call the function two or more times, each time with different input arrays that were potentially different lengths; the length would therefore have to be passed in as a secret hidden variable somehow. And then consider if you passed in an offset into another array, or an array allocated on the heap (malloc
and all being library functions - something the compiler links to, rather than sees and reasons about the body of).
Its getting difficult to imagine how this might work without some behind-the-scenes slice objects and such right?
Symbian did have a AllocSize()
function that returned the size of an allocation with malloc()
; this only worked for the literal pointer returned by the malloc, and you'd get gobbledygook or a crash if you asked it to know the size of an invalid pointer or a pointer offset from one.
You don't want to believe its not possible, but it genuinely isn't. The only way to know the length of something passed into a function is to track the length yourself and pass it in yourself as a separate explicit parameter.
The second quote is correct, the size of a word varies from computer to computer. The ARM NEON architecture is an example of an architecture with 32-bit words, where 64-bit quantities are referred to as "doublewords" and 128-bit quantities are referred to as "quadwords":
A NEON operand can be a vector or a scalar. A NEON vector can be a 64-bit doubleword vector or a 128-bit quadword vector.
Normally speaking, 16-bit words are only found on 16-bit systems, like the Amiga 500.
Every SQL reference I can find says the "any single character" wildcard is the underscore (_
), not the question mark (?
). That simplifies things a bit, since the underscore is not a regex metacharacter. However, you still can't use Pattern.quote()
for the reason given by mmyers. I've got another method here for escaping regexes when I might want to edit them afterward. With that out of the way, the like()
method becomes pretty simple:
public static boolean like(final String str, final String expr)
{
String regex = quotemeta(expr);
regex = regex.replace("_", ".").replace("%", ".*?");
Pattern p = Pattern.compile(regex,
Pattern.CASE_INSENSITIVE | Pattern.DOTALL);
return p.matcher(str).matches();
}
public static String quotemeta(String s)
{
if (s == null)
{
throw new IllegalArgumentException("String cannot be null");
}
int len = s.length();
if (len == 0)
{
return "";
}
StringBuilder sb = new StringBuilder(len * 2);
for (int i = 0; i < len; i++)
{
char c = s.charAt(i);
if ("[](){}.*+?$^|#\\".indexOf(c) != -1)
{
sb.append("\\");
}
sb.append(c);
}
return sb.toString();
}
If you really want to use ?
for the wildcard, your best bet would be to remove it from the list of metacharacters in the quotemeta()
method. Replacing its escaped form -- replace("\\?", ".")
-- wouldn't be safe because there might be backslashes in the original expression.
And that brings us to the real problems: most SQL flavors seem to support character classes in the forms [a-z]
and [^j-m]
or [!j-m]
, and they all provide a way to escape wildcard characters. The latter is usually done by means of an ESCAPE
keyword, which lets you define a different escape character every time. As you can imagine, this complicates things quite a bit. Converting to a regex is probably still the best option, but parsing the original expression will be much harder--in fact, the first thing you would have to do is formalize the syntax of the LIKE
-like expressions themselves.
As an alternative to explicitly catching and handling the exception you could tell Oracle to catch and automatically ignore the exception by including a /*+ hint */
in the insert statement. This is a little faster than explicitly catching the exception and then articulating how it should be handled. It is also easier to setup. The downside is that you do not get any feedback from Oracle that an exception was caught.
Here is an example where we would be selecting from another table, or perhaps an inner query, and inserting the results into a table called TABLE_NAME
which has a unique constraint on a column called IDX_COL_NAME
.
INSERT /*+ ignore_row_on_dupkey_index(TABLE_NAME(IDX_COL_NAME)) */
INTO TABLE_NAME(
INDEX_COL_NAME
, col_1
, col_2
, col_3
, ...
, col_n)
SELECT
INDEX_COL_NAME
, col_1
, col_2
, col_3
, ...
, col_n);
This is not a great solution if your goal it to catch and handle (i.e. print out or update the row that is violating the constraint). But if you just wanted to catch it and ignore the violating row then then this should do the job.
SQL Server recognizes 'TRUE'
and 'FALSE'
as bit
values. So, use a bit
data type!
declare @var bit
set @var = 'true'
print @var
That returns 1
.
You can do it from Visual Studio during debugging without writing any code, not even a catch block.
Just add a watch with the name:
((System.Data.Entity.Validation.DbEntityValidationException)$exception).EntityValidationErrors
The watch expression $exception
displays any exception thrown in the current context, even if it has not been caught and assigned to a variable.
Based on http://mattrandle.me/viewing-entityvalidationerrors-in-visual-studio/

To whom needs list files first than folders (with alphabetical older).
Can use following function. This is not self calling function. So you will have directory list, directory view, files list and folders list as seperated array also.
I spend two days for this and do not want someone will wast his time for this also, hope helps someone.
function dirlist($dir){
if(!file_exists($dir)){ return $dir.' does not exists'; }
$list = array('path' => $dir, 'dirview' => array(), 'dirlist' => array(), 'files' => array(), 'folders' => array());
$dirs = array($dir);
while(null !== ($dir = array_pop($dirs))){
if($dh = opendir($dir)){
while(false !== ($file = readdir($dh))){
if($file == '.' || $file == '..') continue;
$path = $dir.DIRECTORY_SEPARATOR.$file;
$list['dirlist_natural'][] = $path;
if(is_dir($path)){
$list['dirview'][$dir]['folders'][] = $path;
// Bos klasorler while icerisine tekrar girmeyecektir. Klasorun oldugundan emin olalim.
if(!isset($list['dirview'][$path])){ $list['dirview'][$path] = array(); }
$dirs[] = $path;
//if($path == 'D:\Xampp\htdocs\exclusiveyachtcharter.localhost\wp-content\upgrade'){ press($path); press($list['dirview']); die; }
}
else{
$list['dirview'][$dir]['files'][] = $path;
}
}
closedir($dh);
}
}
// if(!empty($dirlist['dirlist_natural'])) sort($dirlist['dirlist_natural'], SORT_LOCALE_STRING); // delete safe ama gerek kalmadi.
if(!empty($list['dirview'])) ksort($list['dirview']);
// Dosyalari dogru siralama yaptiriyoruz. Deniz P. - info[at]netinial.com
foreach($list['dirview'] as $path => $file){
if(isset($file['files'])){
$list['dirlist'][] = $path;
$list['files'] = array_merge($list['files'], $file['files']);
$list['dirlist'] = array_merge($list['dirlist'], $file['files']);
}
// Add empty folders to the list
if(is_dir($path) && array_search($path, $list['dirlist']) === false){
$list['dirlist'][] = $path;
}
if(isset($file['folders'])){
$list['folders'] = array_merge($list['folders'], $file['folders']);
}
}
//press(array_diff($list['dirlist_natural'], $list['dirlist'])); press($list['dirview']); die;
return $list;
}
will output something like this.

I had this issue when trying to push after a rebase through Visual Studio Code, my issue was solved by just copying the command from the git output window and executing it from the terminal window in Visual Studio Code.
In my case the command was something like:
git push origin NameOfMyBranch:NameOfMyBranch
The other option in this particular case would be to type the degree symbol: °
R seems to handle it fine. Type Option-k on a Mac to get it. Not sure about other platforms.
.service-small option {
font-size: 14px;
padding: 5px;
background: #5c5c5c;
}
I think it because you used .styled-select in start of the class code.
There is now official Device Metrics on the Material Design site, those metrics are a hand picked devices list, not an actual statistics, but it too can be really helpful: https://material.io/devices/
you can use more than one useEffect
for example if my variable is data1 i can use all of this in my component
useEffect( () => console.log("mount"), [] );
useEffect( () => console.log("will update data1"), [ data1 ] );
useEffect( () => console.log("will update any") );
useEffect( () => () => console.log("will update data1 or unmount"), [ data1 ] );
useEffect( () => () => console.log("unmount"), [] );
So far, the accepted answer has worked best for me. However, my concern has always been that there is a likely scenario where I might refactor the notebooks
directory into subdirectories, requiring to change the module_path
in every notebook. I decided to add a python file within each notebook directory to import the required modules.
Thus, having the following project structure:
project
|__notebooks
|__explore
|__ notebook1.ipynb
|__ notebook2.ipynb
|__ project_path.py
|__ explain
|__notebook1.ipynb
|__project_path.py
|__lib
|__ __init__.py
|__ module.py
I added the file project_path.py
in each notebook subdirectory (notebooks/explore
and notebooks/explain
). This file contains the code for relative imports (from @metakermit):
import sys
import os
module_path = os.path.abspath(os.path.join(os.pardir, os.pardir))
if module_path not in sys.path:
sys.path.append(module_path)
This way, I just need to do relative imports within the project_path.py
file, and not in the notebooks. The notebooks files would then just need to import project_path
before importing lib
. For example in 0.0-notebook.ipynb
:
import project_path
import lib
The caveat here is that reversing the imports would not work. THIS DOES NOT WORK:
import lib
import project_path
Thus care must be taken during imports.
You see the two empty -D
entries in the g++
command line? They're causing the problem. You must have values in the -D
items e.g. -DWIN32
if you're insistent on using something like -D$(SYSTEM) -D$(ENVIRONMENT) then you can use something like:
SYSTEM ?= generic
ENVIRONMENT ?= generic
in the makefile which gives them default values.
Your output looks to be missing the all important output:
<command-line>:0:1: error: macro names must be identifiers
<command-line>:0:1: error: macro names must be identifiers
just to clarify, what actually got sent to g++
was -D -DWindows_NT
, i.e. define a preprocessor macro called -DWindows_NT
; which is of course not a valid identifier (similarly for -D -I.
)
Dynamic programming problems can be solved using either bottom-up or top-down approaches.
Generally, the bottom-up approach uses the tabulation technique, while the top-down approach uses the recursion (with memorization) technique.
But you can also have bottom-up and top-down approaches using recursion as shown below.
Bottom-Up: Start with the base condition and pass the value calculated until now recursively. Generally, these are tail recursions.
int n = 5;
fibBottomUp(1, 1, 2, n);
private int fibBottomUp(int i, int j, int count, int n) {
if (count > n) return 1;
if (count == n) return i + j;
return fibBottomUp(j, i + j, count + 1, n);
}
Top-Down: Start with the final condition and recursively get the result of its sub-problems.
int n = 5;
fibTopDown(n);
private int fibTopDown(int n) {
if (n <= 1) return 1;
return fibTopDown(n - 1) + fibTopDown(n - 2);
}
Doesn't nth-child return siblings rather than children?
var $selFirst = $(".second:nth-child(1)");
will return the first element with the class '.second'.
var $selFirst = $(".selector:nth-child(1)");
should give you the first sibling of class '.selector'
Sometimes I don't want to add items to a list when I instantiate it.
Instantiate a blank list
Dim blankList As List(Of String) = New List(Of String)
Add to the list
blankList.Add("Dis be part of me list") 'blankList is no longer blank, but you get the drift
Loop through the list
For Each item in blankList
' write code here, for example:
Console.WriteLine(item)
Next
For deleting use http://www.php.net/manual/en/function.unlink.php Hope you'll can to write logic?
Use os.chdir
to change directory .
Use glob.glob
to generate a list of file names which end it '.bak'. The elements of the list are just strings.
Then you could use os.unlink
to remove the files. (PS. os.unlink
and os.remove
are synonyms for the same function.)
#!/usr/bin/env python
import glob
import os
directory='/path/to/dir'
os.chdir(directory)
files=glob.glob('*.bak')
for filename in files:
os.unlink(filename)
There are two ways you could do this. Either create your own custom exception class to represent a divide by zero error or throw the same type of exception the java runtime would throw in this situation.
public class DivideByZeroException() extends ArithmeticException {
}
Then in your code you would check for a divide by zero and throw this exception:
if (divisor == 0) throw new DivideByZeroException();
Add to your code the check for a divide by zero and throw an arithmetic exception:
if (divisor == 0) throw new java.lang.ArithmeticException("/ by zero");
Additionally, you could consider throwing an illegal argument exception since a divisor of zero is an incorrect argument to pass to your setKp() method:
if (divisor == 0) throw new java.lang.IllegalArgumentException("divisor == 0");

If you created imageview using xml file then follow the steps.
Solution 1:
Step 1: Create an XML file
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#cc8181"
>
<ImageView
android:id="@+id/image"
android:layout_width="50dip"
android:layout_height="fill_parent"
android:src="@drawable/icon"
android:layout_marginLeft="3dip"
android:scaleType="center"/>
</LinearLayout>
Step 2: create an Activity
ImageView img= (ImageView) findViewById(R.id.image);
img.setImageResource(R.drawable.my_image);
Solution 2:
If you created imageview from Java Class
ImageView img = new ImageView(this);
img.setImageResource(R.drawable.my_image);

In Debian Linux wget can be configured to use a proxy both via environment variables and via wgetrc. In both cases the variable names to be used for HTTP and HTTPS connections are
http_proxy=hostname_or_IP:portNumber
https_proxy=hostname_or_IP:portNumber
Note that the file /etc/wgetrc takes precedence over the environment variables, hence if your system has a proxy configured there and you try to use the environment variables, they would seem to have no effect!

For anyone trying to run this in nodejs: It won't work out of the box, since jquery needs a browser (or similar)! I was just trying to get the import to run and was logging console.log($)
which wrote [Function]
and then also console.log($.ajax)
which returned undefined
. I had no tsc
errors and had autocomplete from intellij, so I was wondering what's going on.
Then at some point I realised that node
might be the problem and not typescript. I tried the same code in the browser and it worked. To make it work you need to run:
require("jsdom").env("", function(err, window) {
if (err) {
console.error(err);
return;
}
var $ = require("jquery")(window);
});

I extended what Markus Olsson suggested, and came up with this class that adds multiple search strings and a couple of event:
public static class TextLineRemover
{
public static void RemoveTextLines(IList<string> linesToRemove, string filename, string tempFilename)
{
// Initial values
int lineNumber = 0;
int linesRemoved = 0;
DateTime startTime = DateTime.Now;
// Read file
using (var sr = new StreamReader(filename))
{
// Write new file
using (var sw = new StreamWriter(tempFilename))
{
// Read lines
string line;
while ((line = sr.ReadLine()) != null)
{
lineNumber++;
// Look for text to remove
if (!ContainsString(line, linesToRemove))
{
// Keep lines that does not match
sw.WriteLine(line);
}
else
{
// Ignore lines that DO match
linesRemoved++;
InvokeOnRemovedLine(new RemovedLineArgs { RemovedLine = line, RemovedLineNumber = lineNumber});
}
}
}
}
// Delete original file
File.Delete(filename);
// ... and put the temp file in its place.
File.Move(tempFilename, filename);
// Final calculations
DateTime endTime = DateTime.Now;
InvokeOnFinished(new FinishedArgs {LinesRemoved = linesRemoved, TotalLines = lineNumber, TotalTime = endTime.Subtract(startTime)});
}
private static bool ContainsString(string line, IEnumerable<string> linesToRemove)
{
foreach (var lineToRemove in linesToRemove)
{
if(line.Contains(lineToRemove))
return true;
}
return false;
}
public static event RemovedLine OnRemovedLine;
public static event Finished OnFinished;
public static void InvokeOnFinished(FinishedArgs args)
{
Finished handler = OnFinished;
if (handler != null) handler(null, args);
}
public static void InvokeOnRemovedLine(RemovedLineArgs args)
{
RemovedLine handler = OnRemovedLine;
if (handler != null) handler(null, args);
}
}
public delegate void Finished(object sender, FinishedArgs args);
public class FinishedArgs
{
public int TotalLines { get; set; }
public int LinesRemoved { get; set; }
public TimeSpan TotalTime { get; set; }
}
public delegate void RemovedLine(object sender, RemovedLineArgs args);
public class RemovedLineArgs
{
public string RemovedLine { get; set; }
public int RemovedLineNumber { get; set; }
}
Usage:
TextLineRemover.OnRemovedLine += (o, removedLineArgs) => Console.WriteLine(string.Format("Removed \"{0}\" at line {1}", removedLineArgs.RemovedLine, removedLineArgs.RemovedLineNumber));
TextLineRemover.OnFinished += (o, finishedArgs) => Console.WriteLine(string.Format("{0} of {1} lines removed. Time used: {2}", finishedArgs.LinesRemoved, finishedArgs.TotalLines, finishedArgs.TotalTime.ToString()));
TextLineRemover.RemoveTextLines(new List<string> { "aaa", "bbb" }, fileName, fileName + ".tmp");
You can add a row to a table in the most easiest way like this :-
I found this as an easiest way to add row . The awesome thing about this is that it doesn't change the already present table contents even if it contains input elements .
row = `<tr><td><input type="text"></td></tr>`
$("#table_body tr:last").after(row) ;
Here #table_body
is the id of the table body tag .
I ended up doing this in 2 steps. Selected the records I want into a new table in the database then generated a SQL data only script in SSMS. I did find and replace on the generated script and removed the table.
The answer is very similar to existing ones, but slightly optimized.
So you can find any files or folders by pattern:
def iter_all(pattern, path):
return (
os.path.join(root, entry)
for root, dirs, files in os.walk(path)
for entry in dirs + files
if pattern.match(entry)
)
either by substring:
def iter_all(substring, path):
return (
os.path.join(root, entry)
for root, dirs, files in os.walk(path)
for entry in dirs + files
if substring in entry
)
or using a predicate:
def iter_all(predicate, path):
return (
os.path.join(root, entry)
for root, dirs, files in os.walk(path)
for entry in dirs + files
if predicate(entry)
)
to search only files or only folders - replace “dirs + files”, for example, with only “dirs” or only “files”, depending on what you need.
Regards.

Remark: Spark is intended to work on Big Data - distributed computing. The size of the example DataFrame is very small, so the order of real-life examples can be altered with respect to the small ~ example.
Slowest: Method_1, because .describe("A") calculates min, max, mean, stddev, and count (5 calculations over the whole column)
Medium: Method_4, because, .rdd (DF to RDD transformation) slows down the process.
Faster: Method_3 ~ Method_2 ~ method_5, because the logic is very similar, so Spark's catalyst optimizer follows very similar logic with minimal number of operations (get max of a particular column, collect a single-value dataframe); (.asDict() adds a little extra-time comparing 3,2 to 5)

Using alias:
UPDATE t
SET t.col1 = o.col1
FROM table1 AS t
INNER JOIN
table2 AS o
ON t.id = o.id
There are two formats of case expression. You can do CASE
with many WHEN
as;
CASE WHEN Col1 = 1 OR Col3 = 1 THEN 1
WHEN Col1 = 2 THEN 2
...
ELSE 0 END as Qty
Or a Simple CASE
expression
CASE Col1 WHEN 1 THEN 11 WHEN 2 THEN 21 ELSE 13 END
Or CASE
within CASE
as;
CASE WHEN Col1 < 2 THEN
CASE Col2 WHEN 'X' THEN 10 ELSE 11 END
WHEN Col1 = 2 THEN 2
...
ELSE 0 END as Qty
I had this issue. Mine wasn't working because I was putting my files in the .git folder inside my project.

talonmies' answer above is a fine way to abort an application in an assert
-style manner.
Occasionally we may wish to report and recover from an error condition in a C++ context as part of a larger application.
Here's a reasonably terse way to do that by throwing a C++ exception derived from std::runtime_error
using thrust::system_error
:
#include <thrust/system_error.h>
#include <thrust/system/cuda/error.h>
#include <sstream>
void throw_on_cuda_error(cudaError_t code, const char *file, int line)
{
if(code != cudaSuccess)
{
std::stringstream ss;
ss << file << "(" << line << ")";
std::string file_and_line;
ss >> file_and_line;
throw thrust::system_error(code, thrust::cuda_category(), file_and_line);
}
}
This will incorporate the filename, line number, and an English language description of the cudaError_t
into the thrown exception's .what()
member:
#include <iostream>
int main()
{
try
{
// do something crazy
throw_on_cuda_error(cudaSetDevice(-1), __FILE__, __LINE__);
}
catch(thrust::system_error &e)
{
std::cerr << "CUDA error after cudaSetDevice: " << e.what() << std::endl;
// oops, recover
cudaSetDevice(0);
}
return 0;
}
The output:
$ nvcc exception.cu -run
CUDA error after cudaSetDevice: exception.cu(23): invalid device ordinal
A client of some_function
can distinguish CUDA errors from other kinds of errors if desired:
try
{
// call some_function which may throw something
some_function();
}
catch(thrust::system_error &e)
{
std::cerr << "CUDA error during some_function: " << e.what() << std::endl;
}
catch(std::bad_alloc &e)
{
std::cerr << "Bad memory allocation during some_function: " << e.what() << std::endl;
}
catch(std::runtime_error &e)
{
std::cerr << "Runtime error during some_function: " << e.what() << std::endl;
}
catch(...)
{
std::cerr << "Some other kind of error during some_function" << std::endl;
// no idea what to do, so just rethrow the exception
throw;
}
Because thrust::system_error
is a std::runtime_error
, we can alternatively handle it in the same manner of a broad class of errors if we don't require the precision of the previous example:
try
{
// call some_function which may throw something
some_function();
}
catch(std::runtime_error &e)
{
std::cerr << "Runtime error during some_function: " << e.what() << std::endl;
}
I think what you need might be simply:
\d( \w)?
Note that your regex would have worked too if it was written as \d \w|\d
instead of \d|\d \w
.
This is because in your case, once the regex matches the first option, \d
, it ceases to search for a new match, so to speak.
Here are the examples of Filter, map and reduce functions.
numbers = [10,11,12,22,34,43,54,34,67,87,88,98,99,87,44,66]
//Filter
oddNumbers = list(filter(lambda x: x%2 != 0, numbers))
print(oddNumbers)
//Map
multiplyOf2 = list(map(lambda x: x*2, numbers))
print(multiplyOf2)
//Reduce
The reduce function, since it is not commonly used, was removed from the built-in functions in Python 3. It is still available in the functools module, so you can do:
from functools import reduce
sumOfNumbers = reduce(lambda x,y: x+y, numbers)
print(sumOfNumbers)
$("body").on({
click: function(){alert("left click");},
contextmenu: function(){alert("right click");}
});
There is indeed such a tool, Comeau's C++ compiler. . It will generate C code which you can't manually maintain, but that's no problem. You'll maintain the C++ code, and just convert to C on the fly.
If you are having any one or more row(s) with less or more number of columns than 2 in the dataset then this error may arise.
I am also new to Pyspark and trying to read CSV file. Following code worked for me:
In this code I am using dataset from kaggle the link is: https://www.kaggle.com/carrie1/ecommerce-data
1. Without mentioning the schema:
from pyspark.sql import SparkSession
scSpark = SparkSession \
.builder \
.appName("Python Spark SQL basic example: Reading CSV file without mentioning schema") \
.config("spark.some.config.option", "some-value") \
.getOrCreate()
sdfData = scSpark.read.csv("data.csv", header=True, sep=",")
sdfData.show()
Now check the columns: sdfData.columns
Output will be:
['InvoiceNo', 'StockCode','Description','Quantity', 'InvoiceDate', 'CustomerID', 'Country']
Check the datatype for each column:
sdfData.schema
StructType(List(StructField(InvoiceNo,StringType,true),StructField(StockCode,StringType,true),StructField(Description,StringType,true),StructField(Quantity,StringType,true),StructField(InvoiceDate,StringType,true),StructField(UnitPrice,StringType,true),StructField(CustomerID,StringType,true),StructField(Country,StringType,true)))
This will give the data frame with all the columns with datatype as StringType
2. With schema: If you know the schema or want to change the datatype of any column in the above table then use this (let's say I am having following columns and want them in a particular data type for each of them)
from pyspark.sql import SparkSession
from pyspark.sql.types import StructType, StructField
from pyspark.sql.types import DoubleType, IntegerType, StringType
schema = StructType([\
StructField("InvoiceNo", IntegerType()),\
StructField("StockCode", StringType()), \
StructField("Description", StringType()),\
StructField("Quantity", IntegerType()),\
StructField("InvoiceDate", StringType()),\
StructField("CustomerID", DoubleType()),\
StructField("Country", StringType())\
])
scSpark = SparkSession \
.builder \
.appName("Python Spark SQL example: Reading CSV file with schema") \
.config("spark.some.config.option", "some-value") \
.getOrCreate()
sdfData = scSpark.read.csv("data.csv", header=True, sep=",", schema=schema)
Now check the schema for datatype of each column:
sdfData.schema
StructType(List(StructField(InvoiceNo,IntegerType,true),StructField(StockCode,StringType,true),StructField(Description,StringType,true),StructField(Quantity,IntegerType,true),StructField(InvoiceDate,StringType,true),StructField(CustomerID,DoubleType,true),StructField(Country,StringType,true)))
Edited: We can use the following line of code as well without mentioning schema explicitly:
sdfData = scSpark.read.csv("data.csv", header=True, inferSchema = True)
sdfData.schema
The output is:
StructType(List(StructField(InvoiceNo,StringType,true),StructField(StockCode,StringType,true),StructField(Description,StringType,true),StructField(Quantity,IntegerType,true),StructField(InvoiceDate,StringType,true),StructField(UnitPrice,DoubleType,true),StructField(CustomerID,IntegerType,true),StructField(Country,StringType,true)))
The output will look like this:
sdfData.show()
+---------+---------+--------------------+--------+--------------+----------+-------+

add the library under COM object for window media player then type your code where you want
Source:
WMPLib.WindowsMediaPlayer wplayer = new WMPLib.WindowsMediaPlayer();
wplayer.URL = @"C:\Users\Adil M\Documents\Visual Studio 2012\adil.mp3";
wplayer.controls.play();
In Angular $http case, the success() and error() function will have response object been unwrapped, so the callback signature would be like $http(...).success(function(data, status, headers, config))
for then(), you probably will deal with the raw response object. such as posted in AngularJS $http API document
$http({
url: $scope.url,
method: $scope.method,
cache: $templateCache
})
.success(function(data, status) {
$scope.status = status;
$scope.data = data;
})
.error(function(data, status) {
$scope.data = data || 'Request failed';
$scope.status = status;
});
The last .catch(...) will not need unless there is new error throw out in previous promise chain.
You've already got it: A if test else B
is a valid Python expression. The only problem with your dict comprehension as shown is that the place for an expression in a dict comprehension must have two expressions, separated by a colon:
{ (some_key if condition else default_key):(something_if_true if condition
else something_if_false) for key, value in dict_.items() }
The final if
clause acts as a filter, which is different from having the conditional expression.
If it is MySql you can try
SELECT @n := @n + 1 n,
first_name,
last_name
FROM table1, (SELECT @n := 0) m
ORDER BY first_name, last_name
And for SQLServer
SELECT row_number() OVER (ORDER BY first_name, last_name) n,
first_name,
last_name
FROM table1
You can do
<CheckBox
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="right|center"//or "center_vertical" for center text
android:layoutDirection="rtl"
android:text="hello" />
Following line is enough
android:layoutDirection="rtl"
//query is your json
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost postRequest = new HttpPost("http://my.site/test/v1/product/search?qy=");
StringEntity input = new StringEntity(query, "UTF-8");
input.setContentType("application/json");
postRequest.setEntity(input);
HttpResponse response=response = httpClient.execute(postRequest);
I'm using an MVC / MVA design pattern, with multiple types of "views". One type is a "GuiView", which is a Tk window. I pass a view reference to my window object which does things like link buttons back to view functions (which the adapter / controller class also calls).
In order to do that, the view object constructor needed to be completed prior to creating the window object. After creating and displaying the window, I wanted to do some initial tasks with the view automatically. At first I tried doing them post mainloop(), but that didn't work because mainloop() blocked!
As such, I created the window object and used tk.update() to draw it. Then, I kicked off my initial tasks, and finally started the mainloop.
import Tkinter as tk
class Window(tk.Frame):
def __init__(self, master=None, view=None ):
tk.Frame.__init__( self, master )
self.view_ = view
""" Setup window linking it to the view... """
class GuiView( MyViewSuperClass ):
def open( self ):
self.tkRoot_ = tk.Tk()
self.window_ = Window( master=None, view=self )
self.window_.pack()
self.refresh()
self.onOpen()
self.tkRoot_.mainloop()
def onOpen( self ):
""" Do some initial tasks... """
def refresh( self ):
self.tkRoot_.update()
If you just want to execute the shell command in your c program, you could use,
#include <stdlib.h>
int system(const char *command);
In your case,
system("pwd");
The issue is that there isn't an executable file called "pwd" and I'm unable to execute "echo $PWD", since echo is also a built-in command with no executable to be found.
What do you mean by this? You should be able to find the mentioned packages in /bin/
sudo find / -executable -name pwd
sudo find / -executable -name echo
I was having this issue with a linked server in SSMS while trying to create a stored procedure.
On the linked server, I changed the server option "Enable Promotion on Distributed Transaction" to False.
I did it using below steps:
git reset --hard <commit key of the pull request>
git add
git commit --amend
git push -f origin <name of the remote branch of pull request>
Avoid this as well <? } ?>
make sure you put <?php } ?>
And, just to throw it in the mix, is the oft-forgotten str.translate
which will work a lot faster than looping/regular expressions:
For Python 2:
from string import digits
s = 'abc123def456ghi789zero0'
res = s.translate(None, digits)
# 'abcdefghizero'
For Python 3:
from string import digits
s = 'abc123def456ghi789zero0'
remove_digits = str.maketrans('', '', digits)
res = s.translate(remove_digits)
# 'abcdefghizero'
You need an additional library for code coverage, and you are going to be blown away by how powerful and easy istanbul is. Try the following, after you get your mocha tests to pass:
npm install nyc
Now, simply place the command nyc in front of your existing test command, for example:
{
"scripts": {
"test": "nyc mocha"
}
}
Think I figured out how to do it:
- (void)drawRect:(NSRect)dirtyRect {
// Fill in background Color
CGContextRef context = (CGContextRef) [[NSGraphicsContext currentContext] graphicsPort];
CGContextSetRGBFillColor(context, 0.227,0.251,0.337,0.8);
CGContextFillRect(context, NSRectToCGRect(dirtyRect));
}
The statement
if A:
will call A.__nonzero__()
(see Special method names documentation) and use the return value of that function. Here's the summary:
object.__nonzero__(self)
Called to implement truth value testing and the built-in operation
bool()
; should returnFalse
orTrue
, or their integer equivalents0
or1
. When this method is not defined,__len__()
is called, if it is defined, and the object is considered true if its result is nonzero. If a class defines neither__len__()
nor__nonzero__()
, all its instances are considered true.
On the other hand,
if A is not None:
compares only the reference A
with None
to see whether it is the same or not.
public static void main(String[] args) {
String s = "name=john age=13 year=2001";
String t = s.replaceAll(" ", "");
System.out.println("s: " + s + ", t: " + t);
}
Output:
s: name=john age=13 year=2001, t: name=johnage=13year=2001
In Servlet technology if you want to pass any input to a particular servlet then you need to pass in init param like below code.
<servlet>
<servlet-name>DBController</servlet-name>
<servlet-class>com.test.controller.DBController</servlet-class>
<init-param>
<param-name>username</param-name>
<param-value>John</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>DBController</servlet-name>
<url-pattern>/DBController</url-pattern>
</servlet-mapping>
If you want to pass some in put that is common for all servlets then that time you need to configure context param. Example
<context-param>
<param-name>email</param-name>
<param-value>[email protected]</param-value>
</context-param>
SO exactly like this when ever we are working with Spring MVC we need to provide some information to Predefined servlet provided by Spring that is DispatcherServlet through init param. So the configuration is as fallows, here we are providing the spring-servlet.xml as init parameter to DispatcherServlet.
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
id="WebApp_ID" version="3.0">
<display-name>Spring MVC App</display-name>
<servlet>
<servlet-name>SpringController</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>SpringController</servlet-name>
<url-pattern>*.htm</url-pattern>
</servlet-mapping>
</web-app>
Again we need some context param. That is applicable for whole application. So we can provide the root context that is applicationcontext.xml The configuration is like this:
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationcontext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>SpringController</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>SpringController</servlet-name>
<url-pattern>*.htm</url-pattern>
</servlet-mapping>
There is also deltree if you're on an older version of windows.
You can learn more about it from here: SS64: DELTREE - Delete all subfolders and files.
In JavaScript Arrays and Objects are actually very similar, although on the outside they can look a bit different.
For an array:
var array = [];
array[0] = "hello";
array[1] = 5498;
array[536] = new Date();
As you can see arrays in JavaScript can be sparse (valid indicies don't have to be consecutive) and they can contain any type of variable! That's pretty convenient.
But as we all know JavaScript is strange, so here are some weird bits:
array["0"] === "hello"; // This is true
array["hi"]; // undefined
array["hi"] = "weird"; // works but does not save any data to array
array["hi"]; // still undefined!
This is because everything in JavaScript is an Object (which is why you can also create an array using new Array()
). As a result every index in an array is turned into a string and then stored in an object, so an array is just an object that doesn't allow anyone to store anything with a key that isn't a positive integer.
So what are Objects?
Objects in JavaScript are just like arrays but the "index" can be any string.
var object = {};
object[0] = "hello"; // OK
object["hi"] = "not weird"; // OK
You can even opt to not use the square brackets when working with objects!
console.log(object.hi); // Prints 'not weird'
object.hi = "overwriting 'not weird'";
You can go even further and define objects like so:
var newObject = {
a: 2,
};
newObject.a === 2; // true
I had the same issue after I tried to restart mysql.
I use the following two aliases in my .profile for convenience
alias mysql-stop='launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist'
alias mysql-start='launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist'
After stoping mysql and then trying to restart I experienced the issue you were having. I looked into the launchctl load and it was reporting a “nothing found to load” error.
After a quick search I found this..
http://www.daveoncode.com/2013/02/01/solve-mac-osx-launchctl-nothing-found-to-load-error/
So I updated me mysql-start
alias as follows
alias mysql-start='launchctl load -w -F ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist'
This solved my issue which may be useful for you.
First include the header corresponding to the .cpp... in other words, source1.cpp
should include source1.h
before including anything else. The only exception I can think of is when using MSVC with pre-compiled headers in which case, you are forced to include stdafx.h
before anything else.
Reasoning: Including the source1.h
before any other files ensures that it can stand alone without it's dependencies. If source1.h
takes on a dependency on a later date, the compiler will immediately alert you to add the required forward declarations to source1.h
. This in turn ensures that headers can be included in any order by their dependants.
Example:
source1.h
class Class1 {
Class2 c2; // a dependency which has not been forward declared
};
source1.cpp
#include "source1.h" // now compiler will alert you saying that Class2 is undefined
// so you can forward declare Class2 within source1.h
...
MSVC users: I strongly recommend using pre-compiled headers. So, move all #include
directives for standard headers (and other headers which are never going to change) to stdafx.h
.
SELECT id, GROUP_CONCAT( string SEPARATOR ' ') FROM table GROUP BY id
More details here.
From the link above, GROUP_CONCAT
: This function returns a string result with the concatenated non-NULL values from a group. It returns NULL if there are no non-NULL values.
Change your Tomcat
port address to 8084
and Shut Down Port
to 8025
. This will resolve your problem.
In other cases antivirus programs may cause problems. I had this problem with K7 total security. In my case K7 Firewall was blocking the 8084 port. The simple solution is to add an exception to Netbeans in K7 Firewall list.
In order to do that, open K7 and goto Settings -> Firewall Settings -> select Applications tab and find Netbeans.
Select Netbeans and click on edit link. On next screen select Grant Full Network access radio button.
Now goto Netbeans and start the server.
Integers, as was mentioned, are whole numbers. They can't store the point something, like .7, .42, and .007. If you need to store numbers that are not whole numbers, you need a different type of variable. You can use the double type or the float type. You set these types of variables up in exactly the same way: instead of using the word int
, you type double
or float
. Like this:
float myFloat;
double myDouble;
(float
is short for "floating point", and just means a number with a point something on the end.)
The difference between the two is in the size of the numbers that they can hold. For float
, you can have up to 7 digits in your number. For double
s, you can have up to 16 digits. To be more precise, here's the official size:
float: 1.5 × 10^-45 to 3.4 × 10^38
double: 5.0 × 10^-324 to 1.7 × 10^308
float
is a 32-bit number, and double
is a 64-bit number.
Double click your new button to get at the code. Add the following three lines to your button code:
double myDouble;
myDouble = 0.007;
MessageBox.Show(myDouble.ToString());
Halt your program and return to the coding window. Change this line:
myDouble = 0.007;
myDouble = 12345678.1234567;
Run your programme and click your double button. The message box correctly displays the number. Add another number on the end, though, and C# will again round up or down. The moral is if you want accuracy, be careful of rounding!
You can try this:
//custom date for example
$d1 = new DateTime("2012-07-08");
$d2 = new DateTime("2012-07-11");
$d3 = new DateTime("2012-07-08");
$d4 = new DateTime("2012-07-15");
//create a date period object
$interval = new DateInterval('P1D');
$daterange = iterator_to_array(new DatePeriod($d1, $interval, $d2));
$daterange1 = iterator_to_array(new DatePeriod($d3, $interval, $d4));
array_map(function($v) use ($daterange1) { if(in_array($v, $daterange1)) print "Bingo!";}, $daterange);
Convert Integer to Binary:
import java.util.Scanner;
public class IntegerToBinary {
public static void main(String[] args) {
Scanner input = new Scanner( System.in );
System.out.println("Enter Integer: ");
String integerString =input.nextLine();
System.out.println("Binary Number: "+Integer.toBinaryString(Integer.parseInt(integerString)));
}
}
Output:
Enter Integer:
10
Binary Number: 1010

why not? ^_^
See the example here
If there is an interface anywhere in the ThreadProvider hierarchy try putting the name of the Interface as the type of your service provider, eg. if you have say this structure:
public class ThreadProvider implements CustomInterface{
...
}
Then in your controller try this:
@Controller
public class ChiusuraController {
@Autowired
private CustomInterface chiusuraProvider;
}
The reason why this is happening is, in your first case when you DID NOT have ChiusuraProvider
extend ThreadProvider
Spring probably was underlying creating a CGLIB based proxy for you(to handle the @Transaction).
When you DID extend from ThreadProvider
assuming that ThreadProvider extends some interface, Spring in that case creates a Java Dynamic Proxy based Proxy, which would appear to be an implementation of that interface instead of being of ChisuraProvider
type.
If you absolutely need to use ChisuraProvider
you can try AspectJ as an alternative or force CGLIB based proxy in the case with ThreadProvider also this way:
<aop:aspectj-autoproxy proxy-target-class="true"/>
Here is some more reference on this from the Spring Reference site: http://static.springsource.org/spring/docs/3.1.x/spring-framework-reference/html/classic-aop-spring.html#classic-aop-pfb
#include<stdio.h>
#include<string.h>
#define filename "somefile.txt"
int main()
{
FILE *fp;
int count[26] = {0}, i, c;
char ch;
char alpha[27] = "abcdefghijklmnopqrstuwxyz";
fp = fopen(filename,"r");
if(fp == NULL)
printf("file not found\n");
while( (ch = fgetc(fp)) != EOF) {
c = 0;
while(alpha[c] != '\0') {
if(alpha[c] == ch) {
count[c]++;
}
c++;
}
}
for(i = 0; i<26;i++) {
printf("character %c occured %d number of times\n",alpha[i], count[i]);
}
return 0;
}
There are apparently different levels of authentication. Most articles I read tell you to set the MaxAllowedZone to '1' which means that local machine zone and intranet zone are allowed but '4' allows access for 'all' zones.
For more info, read this article: https://support.microsoft.com/en-us/kb/892675
This is how my registry looks (I wasn't sure it would work with the wild cards but it seems to work for me):
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions]
"MaxAllowedZone"=dword:00000004
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions]
"UrlAllowList"="\\\\<network_path_root>;\\\\<network_path_root>\*;\\ies-inc.local;http://www.*;http://*;https://www.*;https://*;"
As an additional note, weirdly the "UrlAllowList" key was required to make this work on another PC but not my test one. It's probably not required at all but when I added it, it fixed the problem. The user may have not closed the original file or something like that. So just a consideration. I suggest try the least and test it, then add if needed. Once you confirm, you can deploy if needed. Good Luck!
Edit: P.S. Another method that worked was mapping the path to the network locally by using mklink /d (symbolic linking in Windows 7 or newer) but mapping a network drive letter (Z: for testing) did not work. Just food for thought and I did not have to 'Unblock' any files. Also the accepted 'Solution' did not resolve the issue for me.
I might have a solution for the video as background, stretched to the browser-width or height, (but the video will still preserve the aspect ratio, couldnt find a solution for that yet.):
Put the video right after the body-tag with style="width:100%;"
.
Right afterwords, put a "bodydummy"-tag:
<body>
<video id="bgVideo" autoplay poster="videos/poster.png">
<source src="videos/test-h264-640x368-highqual-winff.mp4" type="video/mp4"/>
<source src="videos/test-640x368-webmvp8-miro.webm" type="video/webm"/>
<source src="videos/test-640x368-theora-miro.ogv" type="video/ogg"/>
</video>
<img id="bgImg" src="videos/poster.png" />
<!-- This image stretches exactly to the browser width/height and lies behind the video-->
<div id="bodyDummy">
Put all your content inside the bodydummy
-div and put the z-indexes correctly in CSS like this:
#bgImg{
position: absolute;
top: 0;
left: 0;
border: 0;
z-index: 1;
width: 100%;
height: 100%;
}
#bgVideo{
position: absolute;
top: 0;
left: 0;
border: 0;
z-index: 2;
width: 100%;
height: 100%;
}
#bodyDummy{
position: absolute;
top: 0;
left: 0;
z-index: 3;
overflow: auto;
width: 100%;
height: 100%;
}
Hope I could help. Let me know when you could find a solution that the video does not maintain the aspect ratio, so it could fill the whole browser window so we do not have to put a bgimage.
Try jcabi-xml, with a one liner:
Node node = new XMLDocument("<node>value</node>").node();
I've read through all the answers and I'd like to add one more that I think wins out because of its simplicity. Unlike the accepted answer this does not require recursion. It also does not require referencing a FileSystemObject.
Function FileNameFromPath(strFullPath As String) As String
FileNameFromPath = Right(strFullPath, Len(strFullPath) - InStrRev(strFullPath, "\"))
End Function
http://vba-tutorial.com/parsing-a-file-string-into-path-filename-and-extension/ has this code plus other functions for parsing out the file path, extension and even the filename without the extension.
If you do want to use null
values with '='
or '<>'
operators you may find the
very useful.
Short example for '='
: The expression
WHERE t.field = :param
you refactor like this
WHERE ((:param is null and t.field is null) or t.field = :param)
Now you can set the parameter param
either to some non-null value or to null
:
query.setParameter("param", "Hello World"); // Works
query.setParameter("param", null); // Works also
Adding on top of @VonC superb answer, here is a ZSH function that you can add into your .zshrc file:
dockstop() {
docker rm $(docker stop $(docker ps -a -q --filter ancestor="$1" --format="{{.ID}}"))
}
Then in your command line, simply do dockstop myImageName
and it will stop and remove all containers that were started from an image called myImageName.
Also use NVL2
as below if you want to return other value from the field_to_check
:
NVL2( field_to_check, value_if_NOT_null, value_if_null )
Usage: ORACLE/PLSQL: NVL2 FUNCTION
There isn't a great way to do it out of the box. If you want to be using your cleaner syntax on a regular basis, then you can create a utility class to help out:
public class OptionalEx {
private boolean isPresent;
private OptionalEx(boolean isPresent) {
this.isPresent = isPresent;
}
public void orElse(Runnable runner) {
if (!isPresent) {
runner.run();
}
}
public static <T> OptionalEx ifPresent(Optional<T> opt, Consumer<? super T> consumer) {
if (opt.isPresent()) {
consumer.accept(opt.get());
return new OptionalEx(true);
}
return new OptionalEx(false);
}

Then you can use a static import elsewhere to get syntax that is close to what you're after:
import static com.example.OptionalEx.ifPresent;
ifPresent(opt, x -> System.out.println("found " + x))
.orElse(() -> System.out.println("NOT FOUND"));
The c++ inline
keyword is misleading, it doesn't mean "inline this function". If a function is defined as inline, it simply means that it can be defined multiple times as long as all definitions are equal. It's perfectly legal for a function marked inline
to be a real function that is called instead of getting code inlined at the point where it's called.
Defining a function in a header file is needed for templates, since e.g. a templated class isn't really a class, it's a template for a class which you can make multiple variations of. In order for the compiler to be able to e.g. make a Foo<int>::bar()
function when you use the Foo template to create a Foo class, the actual definition of Foo<T>::bar()
must be visible.
To expand on BalusC's answer, any scenario where the sender continues to write after the peer has stopped reading and closed its socket will produce this exception, as will the peer closing while it still had unread data in its own socket receive buffer. In other words, an application protocol error. For example, if you write something to the peer that the peer doesn't understand, and then it closes its socket in protest, and you then continue to write, the peer's TCP stack will issue an RST, which results in this exception and message at the sender.
In my case easiest way to get browser headers was to use php. It appends headers to file and prints them to test page.
<?php
$fp = fopen('m:/temp/requests.txt', 'a');
$time = $_SERVER['REQUEST_TIME'];
fwrite($fp, $time "\n");
echo "$time.<br>";
foreach (getallheaders() as $name => $value) {
$cur_hd = "$name: $value\n";
fwrite($fp, $cur_hd);
echo "$cur_hd.<br>";
}
fwrite($fp, "***\n");
fclose($fp);
?>
Use pd.set_option('display.max_colwidth', None)
for automatic linebreaks and multi-line cells.
This is a great resource on how to use jupyters display with pandas to the fullest.
Edited:
Used to be pd.set_option('display.max_colwidth', -1)
.
What about something like this?
>>> bin(int('ff', base=16))
'0b11111111'
This will convert the hexadecimal string you have to an integer and that integer to a string in which each byte is set to 0/1 depending on the bit-value of the integer.
As pointed out by a comment, if you need to get rid of the 0b
prefix, you can do it this way:
>>> bin(int('ff', base=16)).lstrip('0b')
'11111111'
or this way:
>>> bin(int('ff', base=16))[2:]
'11111111'
I tried everything suggested on here and many other sites, I eventually figured out that the problem was with Bitdefender blocking aapt....
If you have Bitdefender installed then you need to turn aapt & aapt2 "Application Access" on individually.
Hope this is of use.
You could use
options(warn=-1)
But note that turning off warning messages globally might not be a good idea.
To turn warnings back on, use
options(warn=0)
(or whatever your default is for warn
, see this answer)
It is an error about react-scripts file missing in your node_modules/
directory at the time of installation.
Check your react-script dependency is avaliable or not in package.json
.
If not available then add it manually via:
npm install react-scripts --save
unset($a->new_property);
This works for array elements, variables, and object attributes.
Example:
$a = new stdClass();
$a->new_property = 'foo';
var_export($a); // -> stdClass::__set_state(array('new_property' => 'foo'))
unset($a->new_property);
var_export($a); // -> stdClass::__set_state(array())
There is no explicitly defined limit. The amount of available address space forms a practical limit.
(Taken from this site). See the docs on Numeric Types where you'll see that Long integers have unlimited precision
. In Python 2, Integers will automatically switch to longs when they grow beyond their limit:
>>> import sys
>>> type(sys.maxsize)
<type 'int'>
>>> type(sys.maxsize+1)
<type 'long'>
for integers we have
The maximum value of an int can be found in Python 2.x with sys.maxint
. It was removed in Python 3, but sys.maxsize
can often be used instead. From the changelog:
The sys.maxint constant was removed, since there is no longer a limit to the value of integers. However, sys.maxsize can be used as an integer larger than any practical list or string index. It conforms to the implementation’s “natural” integer size and is typically the same as sys.maxint in previous releases on the same platform (assuming the same build options).
and, for anyone interested in the difference (Python 2.x):
sys.maxint The largest positive integer supported by Python’s regular integer type. This is at least 2**31-1. The largest negative integer is -maxint-1 — the asymmetry results from the use of 2’s complement binary arithmetic.
sys.maxsize The largest positive integer supported by the platform’s Py_ssize_t type, and thus the maximum size lists, strings, dicts, and many other containers can have.
and for completeness, here's the Python 3 version:
sys.maxsize An integer giving the maximum value a variable of type Py_ssize_t can take. It’s usually 2^31 - 1 on a 32-bit platform and 2^63 - 1 on a 64-bit platform.
There's float("inf")
and float("-inf")
. These can be compared to other numeric types:
>>> import sys
>>> float("inf") > sys.maxsize
True
I believe those who study typography would tell you that 66 characters per a line is supposed to be the most readable width for length. Even so, if you need to debug a machine remotely over an ssh session, most terminals default to 80 characters, 79 just fits, trying to work with anything wider becomes a real pain in such a case. You would also be suprised by the number of developers using vim + screen as a day to day environment.
you can use unlink
to remove the symlink.
For Example:
cd ~/projects/node-redis
npm link
cd ~/projects/node-bloggy
npm link redis # links to your local redis
To reinstall from your package.json:
npm unlink redis
npm install

To elaborate on @Bakuriu's answer above, I've found that this enables me to catch a runtime warning in a similar fashion to how I would catch an error warning, printing out the warning nicely:
import warnings
with warnings.catch_warnings():
warnings.filterwarnings('error')
try:
answer = 1 / 0
except Warning as e:
print('error found:', e)
You will probably be able to play around with placing of the warnings.catch_warnings() placement depending on how big of an umbrella you want to cast with catching errors this way.
I believe that echo
outputs a trailing newline. Try using -n
as a parameter to echo to skip the newline.
You have to set the associatedEmployee on the Vehicle before persisting the Employee.
Employee newEmployee = new Employee("matt");
vehicle1.setAssociatedEmployee(newEmployee);
vehicles.add(vehicle1);
newEmployee.setVehicles(vehicles);
Employee savedEmployee = employeeDao.persistOrMerge(newEmployee);
