This LINQ below will generate the SQL for a left outer join and then take all of the results that don't find a match in your exclusion list.
List<Person> filteredResults =from p in people
join e in exclusions on p.compositeKey equals e.compositeKey into temp
from t in temp.DefaultIfEmpty()
where t.compositeKey == null
select p
let me know if it works!
You can use the npm modules jsdom and htmlparser to create and parse a DOM in Node.JS.
Other options include:
Out of all these options, I prefer using the Node.js option, because it uses the standard W3C DOM accessor methods and I can reuse code on both the client and server. I wish BeautifulSoup's methods were more similar to the W3C dom, and I think converting your HTML to XHTML to write XSLT is just plain sadistic.
A continue
statement without a label will re-execute from the condition the innermost while
or do
loop, and from the update expression of the innermost for
loop. It is often used to early-terminate a loop's processing and thereby avoid deeply-nested if
statements. In the following example continue
will get the next line, without processing the following statement in the loop.
while (getNext(line)) {
if (line.isEmpty() || line.isComment())
continue;
// More code here
}
With a label, continue
will re-execute from the loop with the corresponding label, rather than the innermost loop. This can be used to escape deeply-nested loops, or simply for clarity.
Sometimes continue
is also used as a placeholder in order to make an empty loop body more clear.
for (count = 0; foo.moreData(); count++)
continue;
The same statement without a label also exists in C and C++. The equivalent in Perl is next
.
This type of control flow is not recommended, but if you so choose you can also use continue
to simulate a limited form of goto
. In the following example the continue
will re-execute the empty for (;;)
loop.
aLoopName: for (;;) {
// ...
while (someCondition)
// ...
if (otherCondition)
continue aLoopName;
By the time the query gets to SQL you have to have already expanded the list. The easy way of doing this, if you're using IDs from some internal, trusted data source, where you can be 100% certain they're integers (e.g., if you selected them from your database earlier) is this:
$sql = 'SELECT * WHERE id IN (' . implode(',', $ids) . ')';
If your data are coming from the user, though, you'll need to ensure you're getting only integer values, perhaps most easily like so:
$sql = 'SELECT * WHERE id IN (' . implode(',', array_map('intval', $ids)) . ')';
Why not just use a regular for loop?
for(int i = 0; i < 50 && i < listView.Items.Count; i++)
{
ListViewItem lvi = listView.Items[i];

First the facts, neither is better. As you already mentioned, Tomcat provides a servlet container that supports the Servlet specification (Tomcat 7 supports Servlet 3.0). JBoss AS, a 'complete' application server supports Java EE 6 (including Servlet 3.0) in its current version.
Tomcat is fairly lightweight and in case you need certain Java EE features beyond the Servlet API, you can easily enhance Tomcat by providing the required libraries as part of your application. For example, if you need JPA features you can include Hibernate or OpenEJB and JPA works nearly out of the box.
How to decide whether to use Tomcat or a full stack Java EE
application server:
When starting your project you should have an idea what it requires. If you're in a large enterprise environment JBoss (or any other Java EE server) might be the right choice as it provides built-in support for e.g:
In my opinion Tomcat is a very good fit if it comes to web centric, user facing applications. If backend integration comes into play, a Java EE application server should be (at least) considered. Last but not least, migrating a WAR developed for Tomcat to JBoss should be a 1 day excercise.
Second, you should also take the usage inside your environment into account. In case your organization already runs say 1,000 JBoss instances, you might always go with that regardless of your concrete requirements (consider aspects like cost for operations or upskilling). Of course, this applies vice versa.

Here is how I did it in AngularJS
app = angular.module('MM_Graph')
class Keyboard
constructor: ($injector)->
@.$injector = $injector
@.$window = @.$injector.get('$window') # get reference to $window and $rootScope objects
@.$rootScope = @.$injector.get('$rootScope')
on_Key_Down:($event)=>
@.$rootScope.$broadcast 'keydown', $event # broadcast a global keydown event
if $event.code is 'KeyS' and ($event.ctrlKey or $event.metaKey) # detect S key pressed and either OSX Command or Window's Control keys pressed
@.$rootScope.$broadcast '', $event # broadcast keyup_CtrS event
#$event.preventDefault() # this should be used by the event listeners to prevent default browser behaviour
setup_Hooks: ()=>
angular.element(@.$window).bind "keydown", @.on_Key_Down # hook keydown event in window (only called once per app load)
@
app.service 'keyboard', ($injector)=>
return new Keyboard($injector).setup_Hooks()
Simply check how many CPUs you are allocating. With one CPU you do not need to play with your bios.
sudo du -x -h / | sort -h | tail -40
/tmp
or /home/user_name/.cache
folder if these are taking up a lot of memory. You can do this by running sudo rm -R /path/to/folder
Step 2 outlines fairly common folders to delete from (/tmp
and /home/user_name/.cache
). If you get back other results when running the first command showing you have lots of memory being used elsewhere, I advise being a bit more cautious when deleting from those locations.
well, i just added button
in data.
For Example,
i should code like this:
$(target).DataTable().row.add(message).draw()
And, in message
, i added button like this : [blah, blah ... "<button>Click!</button>"]
and.. it works!
If you intend to use the default VB6 Collection
, then the easiest you can do is:
col1.add array("first key", "first string"), "first key"
col1.add array("second key", "second string"), "second key"
col1.add array("third key", "third string"), "third key"
Then you can list all values:
Dim i As Variant
For Each i In col1
Debug.Print i(1)
Next
Or all keys:
Dim i As Variant
For Each i In col1
Debug.Print i(0)
Next
This will redirect the stderr (which is descriptor 2) to the file descriptor 1 which is the the stdout.
2>&1
Now when perform this you are redirecting the stdout to the file sample.s
myprogram > sample.s
Combining the two commands will result in redirecting both stderr and stdout to sample.s
myprogram > sample.s 2>&1
Redirect to /dev/null
if you want to completely silent your application.
myprogram >/dev/null 2>&1

It should be pretty obvious from your question that you're actually just asking about the difference between git merge
and git rebase
.
So let's suppose you're in the common case - you've done some work on your master branch, and you pull from origin's, which also has done some work. After the fetch, things look like this:
- o - o - o - H - A - B - C (master)
\
P - Q - R (origin/master)
If you merge at this point (the default behavior of git pull), assuming there aren't any conflicts, you end up with this:
- o - o - o - H - A - B - C - X (master)
\ /
P - Q - R --- (origin/master)
If on the other hand you did the appropriate rebase, you'd end up with this:
- o - o - o - H - P - Q - R - A' - B' - C' (master)
|
(origin/master)
The content of your work tree should end up the same in both cases; you've just created a different history leading up to it. The rebase rewrites your history, making it look as if you had committed on top of origin's new master branch (R
), instead of where you originally committed (H
). You should never use the rebase approach if someone else has already pulled from your master branch.
Finally, note that you can actually set up git pull
for a given branch to use rebase instead of merge by setting the config parameter branch.<name>.rebase
to true. You can also do this for a single pull using git pull --rebase
.
In reference to answer 2, when discussing envsubst, you asked:
How can I make it work with the variables that are declared in my .sh script?
The answer is you simply need to export your variables before calling envsubst
.
You can also limit the variable strings you want to replace in the input using the envsubst
SHELL_FORMAT
argument (avoiding the unintended replacement of a string in the input with a common shell variable value - e.g. $HOME
).
For instance:
export VAR1='somevalue' VAR2='someothervalue'
MYVARS='$VAR1:$VAR2'
envsubst "$MYVARS" <source.txt >destination.txt
Will replace all instances of $VAR1
and $VAR2
(and only VAR1
and VAR2
) in source.txt
with 'somevalue'
and 'someothervalue'
respectively.
No, it is not okay to put a link
element in the body tag. See the specification (links to the HTML4.01 specs, but I believe it is true for all versions of HTML):
“This element defines a link. Unlike
A
, it may only appear in theHEAD
section of a document, although it may appear any number of times.”
The easiest command line for this, which includes the PEM output to add it to the keystore, as well as a human readable output and also supports SNI, which is important if you are working with an HTTP server is:
openssl s_client -servername example.com -connect example.com:443 \
</dev/null 2>/dev/null | openssl x509 -text
The -servername option is to enable SNI support and the openssl x509 -text prints the certificate in human readable format.
Morgan :- Morgan is a middleware which will help us to identify the clients who are accessing our application. Basically a logger.
To Use Morgan, We need to follow below steps :-
npm install --save morgan
This will add morgan to json.package file
var morgan = require('morgan');
3> // create a write stream (in append mode)
var accessLogStream = fs.createWriteStream(
path.join(__dirname, 'access.log'), {flags: 'a'}
);
// setup the logger
app.use(morgan('combined', {stream: accessLogStream}));
Note: Make sure you do not plumb above blindly make sure you have every conditions where you need .
Above will automatically create a access.log file to your root once user will access your app.
I started by doing
if ($true) {
"you can write multiple lines here, and the command doesn't run untill you close the bracket"
"like this"
}
Recently found out I could just
&{
get-date
"more stuff"
}
You can use a data-bound control like the Repeater
or ListView
, re-bind it to a list of control properties as needed, and let it generate the controls dynamically.
As an alternative, you can use Response.Redirect(".")
to re-load the same page.
You need to print
to get that output.
You should do
>>> x = "\n".join(['I', 'would', 'expect', 'multiple', 'lines'])
>>> x # this is the value, returned by the join() function
'I\nwould\nexpect\nmultiple\nlines'
>>> print x # this prints your string (the type of output you want)
I
would
expect
multiple
lines
There are plenty of libraries out there. It all depends on how complicated your data structure is (e.g. consider deeply nested keys)
We like object-fields as it also works with deeply nested hierarchies (build for api fields parameter). Here is a simple code example
// const objectFields = require('object-fields');
const array = [ { bad: 'something', good: 'something' }, { bad: 'something', good: 'something' } ];
const retain = objectFields.Retainer(['good']);
retain(array);
console.log(array);
// => [ { good: 'something' }, { good: 'something' } ]

Might as well throw up an actual response with my solution, which was inspired by Peter Liljenberg's:
$ mpstat | awk '$12 ~ /[0-9.]+/ { print 100 - $12"%" }'
0.75%
This will use awk
to print out 100 minus the 12th field (idle), with a percentage sign after it. awk
will only do this for a line where the 12th field has numbers and dots only ($12 ~ /[0-9]+/
).
You can also average five samples, one second apart:
$ mpstat 1 5 | awk 'END{print 100-$NF"%"}'
Test it like this:
$ mpstat 1 5 | tee /dev/tty | awk 'END{print 100-$NF"%"}'
Every iteration you are resetting the sequence of pseudorandom numbers because you are calling srand
with the same seed (since the call to time
is so frequent). Either use a different seed, or call srand
once before you enter the loop.
The Registry locations
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSBuild\ToolsVersions\2.0
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSBuild\ToolsVersions\3.5
give the location for the executable.
But if you need the location where to save the Task extensions, it's on
%ProgramFiles%\MSBuild
enabledBorder: OutlineInputBorder(
borderRadius: BorderRadius.circular(10.0),
borderSide: BorderSide(color: Colors.red)
),
You can try the following solution:
curl -v -X POST -d @payload.xml https://<API Path> -k -H "Content-Type: application/xml;charset=utf-8"
For Java 8 and higher:
String[] test = {"1", "2", "3", "4", "5"};
int[] ints = Arrays.stream(test).mapToInt(Integer::parseInt).toArray();
or you can use the following to compile the all java source files in current directory..
javac *.java
Simple ways to check an empty dict are below:
a= {}
1. if a == {}:
print ('empty dict')
2. if not a:
print ('empty dict')
Although method 1st is more strict as when a = None, method 1 will provide correct result but method 2 will give an incorrect result.
>>> a = "1,2"
>>> a
'1,2'
>>> b = a.split(",")
>>> b
['1', '2']
To parse a CSV file:
f = open(file.csv, "r")
lines = f.read().split("\n") # "\r\n" if needed
for line in lines:
if line != "": # add other needed checks to skip titles
cols = line.split(",")
print cols
As dowski suggested, you could use WMI to get printer properties. The following code displays all properties for a given printer name. Among them you will find: PrinterStatus, Comment, Location, DriverName, PortName, etc.
using System.Management;
...
string printerName = "YourPrinterName";
string query = string.Format("SELECT * from Win32_Printer WHERE Name LIKE '%{0}'", printerName);
using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(query))
using (ManagementObjectCollection coll = searcher.Get())
{
try
{
foreach (ManagementObject printer in coll)
{
foreach (PropertyData property in printer.Properties)
{
Console.WriteLine(string.Format("{0}: {1}", property.Name, property.Value));
}
}
}
catch (ManagementException ex)
{
Console.WriteLine(ex.Message);
}
}
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
.
You need to import the FormsModule
Open app.module.ts
and add line
import { FormsModule } from '@angular/forms';
and
@NgModule({
imports: [
FormsModule
],
})
You can use the filter
function to apply more complicated regex matching.
Here's an example which would just match the first three divs:
$('div')_x000D_
.filter(function() {_x000D_
return this.id.match(/abc+d/);_x000D_
})_x000D_
.html("Matched!");
_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
_x000D_
<div id="abcd">Not matched</div>_x000D_
<div id="abccd">Not matched</div>_x000D_
<div id="abcccd">Not matched</div>_x000D_
<div id="abd">Not matched</div>
_x000D_
You'd be surprised to find out that 80/20 is quite a commonly occurring ratio, often referred to as the Pareto principle. It's usually a safe bet if you use that ratio.
However, depending on the training/validation methodology you employ, the ratio may change. For example: if you use 10-fold cross validation, then you would end up with a validation set of 10% at each fold.
There has been some research into what is the proper ratio between the training set and the validation set:
The fraction of patterns reserved for the validation set should be inversely proportional to the square root of the number of free adjustable parameters.
In their conclusion they specify a formula:
Validation set (v) to training set (t) size ratio, v/t, scales like ln(N/h-max), where N is the number of families of recognizers and h-max is the largest complexity of those families.
What they mean by complexity is:
Each family of recognizer is characterized by its complexity, which may or may not be related to the VC-dimension, the description length, the number of adjustable parameters, or other measures of complexity.
Taking the first rule of thumb (i.e.validation set should be inversely proportional to the square root of the number of free adjustable parameters), you can conclude that if you have 32 adjustable parameters, the square root of 32 is ~5.65, the fraction should be 1/5.65 or 0.177 (v/t). Roughly 17.7% should be reserved for validation and 82.3% for training.
Most databases will accept this:
select * from SomeTable where true
However some databases (eg SQL Server, Oracle) do not have a boolean type. In these cases you may use:
select * from SomeTable where 1=1
BTW, if building up an sql where clause by hand, this is the basis for simplifying your code because you can avoid having to know if the condition you're about to add to a where clause is the first one (which should be preceded by "WHERE"
), or a subsequent one (which should be preceded by "AND"
). By always starting with "WHERE 1=1"
, all conditions (if any) added to the where clause are preceded by "AND"
.

The latest specification allows line feed character, so a simple line break inside the attribute or entity
(note that characters #
and ;
are required) are OK.
You can change from the property of every item.
Here is another method: using SQL Server Management Studio, in Object Explorer, go to your database and select Tables
Then open the Object Explorer Details (either by pressing F7 or going to View->Object Explorer Details). In the object explorer details page, right click on the column header and enable the columns that you would like to see in the page. You can sort the data by any column too.

glob2rx()
converts a pattern including a wildcard into the equivalent regular expression. You then need to pass this regular expression onto one of R's pattern matching tools.
If you want to match "blue*"
where *
has the usual wildcard, not regular expression, meaning we use glob2rx()
to convert the wildcard pattern into a useful regular expression:
> glob2rx("blue*")
[1] "^blue"
The returned object is a regular expression.
Given your data:
x <- c('red','blue1','blue2', 'red2')
we can pattern match using grep()
or similar tools:
> grx <- glob2rx("blue*")
> grep(grx, x)
[1] 2 3
> grep(grx, x, value = TRUE)
[1] "blue1" "blue2"
> grepl(grx, x)
[1] FALSE TRUE TRUE FALSE
As for the selecting rows problem you posted
> a <- data.frame(x = c('red','blue1','blue2', 'red2'))
> with(a, a[grepl(grx, x), ])
[1] blue1 blue2
Levels: blue1 blue2 red red2
> with(a, a[grep(grx, x), ])
[1] blue1 blue2
Levels: blue1 blue2 red red2
or via subset()
:
> with(a, subset(a, subset = grepl(grx, x)))
x
2 blue1
3 blue2
Hope that explains what grob2rx()
does and how to use it?

import numpy
import pylab
xy = numpy.zeros((2, 1000))
xy[0] = range(1000)
xy[1] = range(1000)
colors = [int(i % 23) for i in xy[0]]
pylab.scatter(xy[0], xy[1], c=colors)
pylab.show()
You can also set a cmap
attribute to control which colors will appear through use of a colormap; i.e. replace the pylab.scatter
line with:
pylab.scatter(xy[0], xy[1], c=colors, cmap=pylab.cm.cool)
A list of color maps can be found here
An INNER JOIN
can return data from the columns from both tables, and can duplicate values of records on either side have more than one match. A LEFT SEMI JOIN
can only return columns from the left-hand table, and yields one of each record from the left-hand table where there is one or more matches in the right-hand table (regardless of the number of matches). It's equivalent to (in standard SQL):
SELECT name
FROM table_1 a
WHERE EXISTS(
SELECT * FROM table_2 b WHERE (a.name=b.name))
If there are multiple matching rows in the right-hand column, an INNER JOIN
will return one row for each match on the right table, while a LEFT SEMI JOIN
only returns the rows from the left table, regardless of the number of matching rows on the right side. That's why you're seeing a different number of rows in your result.
I am trying to get the names within table_1 that only appear in table_2.
Then a LEFT SEMI JOIN
is the appropriate query to use.
You can use the following CSS for your input field:

Another clean option that I have found useful is pandas.DataFrame.mask which will "replace values where the condition is true."
Create the DataFrame:
In [2]: import pandas as pd
In [3]: df = pd.DataFrame({'a': [0, -1, 2], 'b': [-3, 2, 1]})
In [4]: df
Out[4]:
a b
0 0 -3
1 -1 2
2 2 1
Replace negative numbers with 0:
In [5]: df.mask(df < 0, 0)
Out[5]:
a b
0 0 0
1 0 2
2 2 1
Or, replace negative numbers with NaN, which I frequently need:
In [7]: df.mask(df < 0)
Out[7]:
a b
0 0.0 NaN
1 NaN 2.0
2 2.0 1.0

Firstly, just to check, you need to change into the directory you've created before running git init --bare
. Also, it's conventional to give bare repositories the extension .git
. So you can do
git init --bare test_repo.git
For Git versions < 1.8 you would do
mkdir test_repo.git
cd test_repo.git
git --bare init
To answer your later questions, bare repositories (by definition) don't have a working tree attached to them, so you can't easily add files to them as you would in a normal non-bare repository (e.g. with git add <file>
and a subsequent git commit
.)
You almost always update a bare repository by pushing to it (using git push
) from another repository.
Note that in this case you'll need to first allow people to push to your repository. When inside test_repo.git
, do
git config receive.denyCurrentBranch ignore
Community edit
git init --bare --shared=group
As commented by prasanthv, this is what you want if you are doing this at work, rather than for a private home project.
I found a tool in Github that could possibly be a solution to this question. https://incarnate.github.io/curl-to-php/ I hope that will be useful
Check that you have database dependency at runtime group at build.gradle
runtime group: 'com.h2database', name: 'h2', version: '1.4.194'
or change scope from test to runtime if you use Maven
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<version>1.4.194</version>
<scope>runtime</scope>
</dependency>
You can do all of it in awk
:
<file awk '$1 ~ /A1/ {m=$NF} END {print m}'
I think you're asking how to compute the mean of a variable in a data frame, given the name of the column. There are two typical approaches to doing this, one indexing with [[
and the other indexing with [
:
data(iris)
mean(iris[["Petal.Length"]])
# [1] 3.758
mean(iris[,"Petal.Length"])
# [1] 3.758
mean(iris[["Sepal.Width"]])
# [1] 3.057333
mean(iris[,"Sepal.Width"])
# [1] 3.057333
If you receive an error stating the library cannot be found, check the Google maven repo for your library and version. I had a version suddenly disappear and make my builds fail.
It's not officially supported yet.
Edit: It's now supported in modern versions of Android Studio, at least on some platforms.
If you're using an old version of Android Studio which doesn't support the Google Play Store, and you refuse to upgrade, here are two possible workarounds:
Ask your favorite app's maintainers to upload a copy of their app into the Amazon Appstore. Next, install the Appstore onto your Android device. Finally, use the Appstore to install your favorite app.
Or: Do a Web search to find a .apk file for the software you want. For example, if you want to install SleepBot in your Android emulator, you can do a Google Web search for [ SleepBot apk
]. Then use adb install
to install the .apk file.
awk 'NF' filename
awk 'NF > 0' filename
sed -i '/^$/d' filename
awk '!/^$/' filename
awk '/./' filename
The NF also removes lines containing only blanks or tabs, the regex /^$/
does not.

As m.edmondson mentioned, "The remote host closed the connection." occurs when a user or browser cancels something, or the network connection drops etc. It doesn't necessarily have to be a file download however, just any request for any resource that results in a response to the client. Basically the error means that the response could not be sent because the server can no longer talk to the client(browser).
There are a number of steps that you can take in order to stop it happening. If you are manually sending something in the response with a Response.Write, Response.Flush, returning data from a web servivce/page method or something similar, then you should consider checking Response.IsClientConnected before sending the response. Also, if the response is likely to take a long time or a lot of server-side processing is required, you should check this periodically until the response.end if called. See the following for details on this property:
http://msdn.microsoft.com/en-us/library/system.web.httpresponse.isclientconnected.aspx
Alternatively, which I believe is most likely in your case, the error is being caused by something inside the framework. The following link may by of use:
The following stack-overflow post might also be of interest:

Because all attempts to print the argument I placed in my variable failed, here my 2 bytes for this question:
std::string dump_name;
(stuff..)
if(argc>2)

Note the use of assign, and also the need for the c_str() function call.
I found another way to solve this one to avoid password of VBA Project,with out loosing excel password.

The C++ standard explicitly talks about this, see section "17.5.2.1.3 Bitmask types":
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2012/n3485.pdf
Given this "template" you get:
enum AnimalFlags : unsigned int
{
HasClaws = 1,
CanFly = 2,
EatsFish = 4,
Endangered = 8
};
constexpr AnimalFlags operator|(AnimalFlags X, AnimalFlags Y) {
return static_cast<AnimalFlags>(
static_cast<unsigned int>(X) | static_cast<unsigned int>(Y));
}
AnimalFlags& operator|=(AnimalFlags& X, AnimalFlags Y) {
X = X | Y; return X;
}
And similar for the other operators. Also note the "constexpr", it is needed if you want the compiler to be able to execute the operators compile time.
If you are using C++/CLI and want to able assign to enum members of ref classes you need to use tracking references instead:
AnimalFlags% operator|=(AnimalFlags% X, AnimalFlags Y) {
X = X | Y; return X;
}
NOTE: This sample is not complete, see section "17.5.2.1.3 Bitmask types" for a complete set of operators.

The easiest way would be to specify
SELECT productid FROM product where purchase_date > sysdate-30;
Remember this sysdate above has the time component, so it will be purchase orders newer than 03-06-2011 8:54 AM based on the time now.
If you want to remove the time conponent when comparing..
SELECT productid FROM product where purchase_date > trunc(sysdate-30);
And (based on your comments), if you want to specify a particular date, make sure you use to_date and not rely on the default session parameters.
SELECT productid FROM product where purchase_date > to_date('03/06/2011','mm/dd/yyyy')
And regardng the between (sysdate-30) - (sysdate) comment, for orders you should be ok with usin just the sysdate condition unless you can have orders with order_dates in the future.
If you follow your link, it tells you that the error results from the $injector not being able to resolve your dependencies. This is a common issue with angular when the javascript gets minified/uglified/whatever you're doing to it for production.
The issue is when you have e.g. a controller;
angular.module("MyApp").controller("MyCtrl", function($scope, $q) {
// your code
})
The minification changes $scope
and $q
into random variables that doesn't tell angular what to inject. The solution is to declare your dependencies like this:
angular.module("MyApp")
.controller("MyCtrl", ["$scope", "$q", function($scope, $q) {
// your code
}])
That should fix your problem.
Just to re-iterate, everything I've said is at the link the error message provides to you.

NodeJS (and newer browsers) have a nice shortcut to get the current time in milliseconds.
var timeInMss = Date.now()
Which has a performance boost compared with
var timeInMss = new Date().getTime()
Because you do not need to create a new object.

Some browsers such as Firefox, Chrome, Safari, Opera and IE10+ can handle Base64 natively. Take a look at this Stackoverflow question. It's using btoa()
and atob()
functions.
For server-side JavaScript (Node), you can use Buffer
s to decode.
If you are going for a cross-browser solution, there are existing libraries like CryptoJS or code like:
http://ntt.cc/2008/01/19/base64-encoder-decoder-with-javascript.html
With the latter, you need to thoroughly test the function for cross browser compatibility. And error has already been reported.
Lot's of great answer. I just want to add a small note about decoupling the stream.
cin.tie(NULL);
I have faced an issue while decoupling the stream with CodeChef platform. When I submitted my code, the platform response was "Wrong Answer" but after tying the stream and testing the submission. It worked.
So, If anyone wants to untie the stream, the output stream must be flushed.
Edit: I am not familiar with all the platform but this is what I have experienced.
Update:
// use it like this
obj?.a?.lot?.of?.properties
Solution for JavaScript before ECMASCript 2020 or TypeScript older than version 3.7:
A quick workaround is using a try/catch helper function with ES6 arrow function:
function getSafe(fn, defaultVal) {
try {
return fn();
} catch (e) {
return defaultVal;
}
}
// use it like this
console.log(getSafe(() => obj.a.lot.of.properties));
// or add an optional default value
console.log(getSafe(() => obj.a.lot.of.properties, 'nothing'));

You can also do cd ......\ as many times as there are folders that takes you to home directory. For example, if you are in cd:\windows\syatem32, then cd ....\ takes you to the home, that is c:\
You can get the current username on Windows by going through the Windows API, although it's a bit cumbersome to invoke via the ctypes FFI (GetCurrentProcess ? OpenProcessToken ? GetTokenInformation ? LookupAccountSid).
I wrote a small module that can do this straight from Python, getuser.py. Usage:
import getuser
print(getuser.lookup_username())
It works on both Windows and *nix (the latter uses the pwd
module as described in the other answers).
Have a look at the documentation. Use the intValue
method:
NSNumber *number = [dict objectForKey:@"integer"];
int intValue = [number intValue];
You will find the application folder at:
/data/data/"your package name"
you can access this folder using the DDMS for your Emulator. you can't access this location on a real device unless you have a rooted device.
Here is one solution to clear all your application's activities when you use the logout button.
Every time you start an Activity, start it like this:
Intent myIntent = new Intent(getBaseContext(), YourNewActivity.class);
startActivityForResult(myIntent, 0);
When you want to close the entire app, do this:
setResult(RESULT_CLOSE_ALL);
finish();
RESULT_CLOSE_ALL is a final global variable with a unique integer to signal you want to close all activities.
Then define every activity's onActivityResult(...)
callback so when an activity returns with the RESULT_CLOSE_ALL value, it also calls finish()
:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch(resultCode)
{
case RESULT_CLOSE_ALL:
setResult(RESULT_CLOSE_ALL);
finish();
}
super.onActivityResult(requestCode, resultCode, data);
}
This will cause a cascade effect that closes all your activities.
This is a hack however and uses startActivityForResult
in a way that it was not designed to be used.
Perhaps a better way to do this would be using broadcast receivers as shown here:

Using Classes in Node -
Here we are requiring the ReadWrite module and calling a makeObject(), which returns the object of the ReadWrite class. Which we are using to call the methods. index.js
const ReadWrite = require('./ReadWrite').makeObject();
const express = require('express');
const app = express();
class Start {
constructor() {
const server = app.listen(8081),
host = server.address().address,
port = server.address().port
console.log("Example app listening at http://%s:%s", host, port);
console.log('Running');
}
async route(req, res, next) {
const result = await ReadWrite.readWrite();
res.send(result);
}
}
const obj1 = new Start();
app.get('/', obj1.route);
module.exports = Start;
ReadWrite.js
Here we making a makeObject method, which makes sure that a object is returned, only if a object is not available.
class ReadWrite {
constructor() {
console.log('Read Write');
this.x;
}
static makeObject() {
if (!this.x) {
this.x = new ReadWrite();
}
return this.x;
}
read(){
return "read"
}
write(){
return "write"
}
async readWrite() {
try {
const obj = ReadWrite.makeObject();
const result = await Promise.all([ obj.read(), obj.write()])
console.log(result);
check();
return result
}
catch(err) {
console.log(err);
}
}
}
module.exports = ReadWrite;

I had the same question and figured it out by using getBoundingClientRect().
This code is completely 'generic' and only has to be written once for it to work (you don't have to write it out for each element that you want to know is in the viewport).
This code only checks to see if it is vertically in the viewport, not horizontally. In this case, the variable (array) 'elements' holds all the elements that you are checking to be vertically in the viewport, so grab any elements you want anywhere and store them there.
The 'for loop', loops through each element and checks to see if it is vertically in the viewport. This code executes every time the user scrolls! If the getBoudingClientRect().top is less than 3/4 the viewport (the element is one quarter in the viewport), it registers as 'in the viewport'.
Since the code is generic, you will want to know 'which' element is in the viewport. To find that out, you can determine it by custom attribute, node name, id, class name, and more.
Here is my code (tell me if it doesn't work; it has been tested in Internet Explorer 11, Firefox 40.0.3, Chrome Version 45.0.2454.85 m, Opera 31.0.1889.174, and Edge with Windows 10, [not Safari yet])...
// Scrolling handlers...
window.onscroll = function(){
var elements = document.getElementById('whatever').getElementsByClassName('whatever');
for(var i = 0; i != elements.length; i++)
{
if(elements[i].getBoundingClientRect().top <= window.innerHeight*0.75 &&
elements[i].getBoundingClientRect().top > 0)
{
console.log(elements[i].nodeName + ' ' +
elements[i].className + ' ' +
elements[i].id +
' is in the viewport; proceed with whatever code you want to do here.');
}
};

When viewing a document: Edit / Advanced / Word Wrap (Ctrl+E, Ctrl+W)

If you're familiar with word wrap in Notepad++, Sublime Text, or Visual Studio Code, be aware of the following issues where Visual Studio behaves differently to other editors:
Unfortunately these bugs have been closed "lower priority". If you'd like these bugs fixed, please vote for the feature request Fix known issues with word wrap.
The issue could be replicated in VS 2019 also. This is caused due to "Enable Javascript debugging from Visual Studio IDE". The VS attaches to Chrome and it is a possibility that due to security or reasons known to Google and Microsoft, it sometimes fails to attach and you have this issue. I am able to run http and https with localhost from ASP net core 3.1 app. So while debugging in VS, go to the run with arrow -> IIS express, just below "Web Browser(Chrome)" select "Script Debugging (Disabled)".

Always fallback to Microsoft docs to get more clarity than googling an issue.
You can also do more succinctly:
df.sort_index(axis=1)
Make sure you assign the result back:
df = df.sort_index(axis=1)
Or, do it in-place:
df.sort_index(axis=1, inplace=True)
You can do this by using JQuery.
For example ,
<a href="your URL" id="navigate"> click here </a>
Your JQuery
will be,
$(document).ready(function(){
$('a').on('mousedown', stopNavigate);
$('a').on('mouseleave', function () {
$(window).on('beforeunload', function(){
return 'Are you sure you want to leave?';
});
});
});
function stopNavigate(){
$(window).off('beforeunload');
}
And to get the Leave message alert will be,
$(window).on('beforeunload', function(){
return 'Are you sure you want to leave?';
});
$(window).on('unload', function(){
logout();
});
This solution works in all browsers and I have tested it.

As mentioned in several answers already that have been already given, you can use ToShorDateString()
:
DateTime.Now.ToShortDateString();
However, you may be a bit blocked if you also want to use the culture as a parameter. In this case you can use the ToString()

I had a similar problem not being able to access phpmyadmin on a testing server after changing the root password. I tried everything mentioned above, including advice from other forums, using all kinds of variations to the config files. THEN I remembered that Google Chrome has some issues working with a testing server. The reason is that Chrome has a security feature to prevent local hard drive access from a remote website - unfortunately this can cause issues in a testing environment because the server is a local hard drive. When I tried to log in to phpmyadmin with Internet Explorer it worked fine. I tried several tests of Chrome v IE9, and Chrome would not work under any configuration with the root password set. I also tested Firefox it also worked fine, the issue is only with Chrome. My advice: if you're on a testing server make sure your config file has the correct settings as described above, but if the problem continues and you're using Chrome try a different browser.
axios signature for post is axios.post(url[, data[, config]])
. So you want to send params object within the third argument:
.post(`/mails/users/sendVerificationMail`, null, { params: {
mail,
firstname
}})
.then(response => response.status)
.catch(err => console.warn(err));
This will POST an empty body with the two query params:
POST http://localhost:8000/api/mails/users/sendVerificationMail?mail=lol%40lol.com&firstname=myFirstName
A very simple and elegant solution to this is provided by W3C. Simply use the margin:0 auto declaration as follows:

Since a ternary operator is usually used when assigning value, it should return a value. This is the way that can work:
$var=@("value if false","value if true")[[byte](condition)]
Stupid, but working. Also this construction can be used to quickly turn an int into another value, just add array elements and specify an expression that returns 0-based non-negative values.

Pandas has the itertuples
method to do exactly this:
list(df[['lat', 'long']].itertuples(index=False, name=None))
I just was in about the same situation a day ago, and here are my 2 cents:
1) I found arguably the shortest and most concise demonstration of multiple model entry in single form here: http://collingrady.wordpress.com/2008/02/18/editing-multiple-objects-in-django-with-newforms/ .
In a nutshell: Make a form for each model, submit them both to template in a single <form>
, using prefix
keyarg and have the view handle validation. If there is dependency, just make sure you save the "parent"
model before dependant, and use parent's ID for foreign key before commiting save of "child" model. The link has the demo.
2) Maybe formsets can be beaten into doing this, but as far as I delved in, formsets are primarily for entering multiples of the same model, which may be optionally tied to another model/models by foreign keys. However, there seem to be no default option for entering more than one model's data and that's not what formset seems to be meant for.
What are the backgrounds for a switch-case to not accept this operator?
Because case
requires constant expression as its value. And since an ||
expression is not a compile time constant, it is not allowed.
From JLS Section 14.11:
Switch label should have following syntax:
SwitchLabel:
case ConstantExpression :
case EnumConstantName :
default :
The reason behind allowing just constant expression with cases can be understood from the JVM Spec Section 3.10 - Compiling Switches:
Compilation of switch statements uses the tableswitch and lookupswitch instructions. The tableswitch instruction is used when the cases of the switch can be efficiently represented as indices into a table of target offsets. The default target of the switch is used if the value of the expression of the switch falls outside the range of valid indices.
So, for the cases label to be used by tableswitch
as a index into the table of target offsets, the value of the case should be known at compile time. That is only possible if the case value is a constant expression. And ||
expression will be evaluated at runtime, and the value will only be available at that time.
From the same JVM section, the following switch-case
:
switch (i) {
case 0: return 0;
case 1: return 1;
case 2: return 2;
default: return -1;
}
is compiled to:
0 iload_1 // Push local variable 1 (argument i)
1 tableswitch 0 to 2: // Valid indices are 0 through 2 (NOTICE This instruction?)
0: 28 // If i is 0, continue at 28
1: 30 // If i is 1, continue at 30
2: 32 // If i is 2, continue at 32
default:34 // Otherwise, continue at 34
28 iconst_0 // i was 0; push int constant 0...
29 ireturn // ...and return it

In the course of developing an in-house address verification service at a German company I used to work for I've come across a number of ways to tackle this issue. I'll do my best to sum up my findings below:
Free, Open Source Software
Clearly, the first approach anyone would take is an open-source one (like openstreetmap.org), which is never a bad idea. But whether or not you can really put this to good and reliable use depends very much on how much you need to rely on the results.
Addresses are an incredibly variable thing. Verifying U.S. addresses is not an easy task, but bearable, but once you're going for Europe, especially the U.K. with their extensive Postal Code system, the open-source approach will simply lack data.
Web Services / APIs
Enterprise-Class Software
Money gets it done, obviously. But not every business or developer can spend ~$0.15 per address lookup (that's $150 for 1,000 API requests) - a very expensive business model the vast majority of address validation APIs have implemented.
What I ended up integrating: streetlayer API
Since I was not willing to take on the programmatic approach of verifying address data manually I finally came to the conclusion that I was in need of an API with a price tag that would not make my boss want to fire me and still deliver solid and reliable international verification results.
Long story short, I ended up integrating an API built by apilayer, called "streetlayer API". I was easily convinced by a simple JSON integration, surprisingly accurate validation results and their developer-friendly pricing. Also, 100 requests/month are entirely free.
Hope this helps!
onblur

type(dict())
says "make a new dict, and then find out what its type is". It's quicker to say just dict
.
But if you want to just check type, a more idiomatic way is isinstance(x, dict)
.
Note, that isinstance
also includes subclasses (thanks Dustin):
class D(dict):
pass
d = D()
print("type(d) is dict", type(d) is dict) # -> False
print("isinstance (d, dict)", isinstance(d, dict)) # -> True
The following should unlock a locked working copy (tested on svn client version 1.6.11 and elipse version: Mars.2 Release (4.5.2))
step 1: (go to working copy directory) $cd working_copy_dir
step 2: (connect to svn sqlite database) $sqlite3 .svn/wc.db
step 3: (delete all records from table WC_LOCK) sqlite> delete from WC_LOCK;
step 4: (disconnect from sqlite 3 database) sqlite>ctrl + d
step 5: (from eclipse) right click on your working copy, then click Team -> Refresh/Cleanup
If you see an empty page, enable JavaScript.
webView.setWebViewClient(new WebViewClient());
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setDomStorageEnabled(true);
webView.loadUrl(url);
Try this
if (ModelState.IsValid)
{
//go on as normal
}
else
{
var errors = ModelState.Select(x => x.Value.Errors)
.Where(y=>y.Count>0)
.ToList();
}
errors will be a list of all the errors.
If you want to display the errors to the user, all you have to do is return the model to the view and if you haven't removed the Razor @Html.ValidationFor()
expressions, it will show up.
if (ModelState.IsValid)
{
//go on as normal
}
else
{
return View(model);
}
The view will show any validation errors next to each field and/or in the ValidationSummary if it's present.
If your sed(1)
has a -i
option, then use it like this:
for i in *; do
sed -i 's/foo/bar/' $i
done
If not, there are several ways variations on the following depending on which language you want to play with:
ruby -i.bak -pe 'sub(%r{foo}, 'bar')' *
perl -pi.bak -e 's/foo/bar/' *

I solved it with a temp table.
CREATE TEMP TABLE temp_session_variables (
"sessionSalt" TEXT
);
INSERT INTO temp_session_variables ("sessionSalt") VALUES (current_timestamp || RANDOM()::TEXT);
This way, I had a "variable" I could use over multiple queries, that is unique for the session. I needed it to generate unique "usernames" while still not having collisions if importing users with the same user name.
Use finish
like this:
Intent i = new Intent(Main_Menu.this, NextActivity.class);
finish(); //Kill the activity from which you will go to next activity
startActivity(i);
FLAG_ACTIVITY_NO_HISTORY
you can use in case for the activity you want to finish. For exampe you are going from A-->B--C. You want to finish activity B when you go from B-->C so when you go from A-->B you can use this flag. When you go to some other activity this activity will be automatically finished.
To learn more on using Intent.FLAG_ACTIVITY_NO_HISTORY
read: http://developer.android.com/reference/android/content/Intent.html#FLAG_ACTIVITY_NO_HISTORY
There's a property that enables/disables in line media playback in the iOS web browser (if you were writing a native app, it would be the allowsInlineMediaPlayback
property of a UIWebView). By default on iPhone this is set to NO
, but on iPad it's set to YES
.
Fortunately for you, you can also adjust this behaviour in HTML as follows:
<video id="myVideo" width="280" height="140" webkit-playsinline>
...that should hopefully sort it out for you. I don't know if it will work on your Android devices. It's a webkit property, so it might. Worth a go, anyway.
Yes. IMHO, overriding GetWebRequest() is the best solution to WebClient's limited functionalty. Before I knew about this option, I wrote lots of really painful code at the HttpWebRequest layer because WebClient almost, but not quite, did what I needed. Derivation is much easier.
Another option is to use the regular WebClient class, but manually populate the Cookie header before making the request and then pull out the Set-Cookies header on the response. There are helper methods on the CookieContainer class which make creating and parsing these headers easier: CookieContainer.SetCookies()
and CookieContainer.GetCookieHeader()
, respectively.
I prefer the former approach since it's easier for the caller and requires less repetitive code than the second option. Also, the derivation approach works the same way for multiple extensibility scenarios (e.g. cookies, proxies, etc.).
If someone is here who is using MySQL and felt that the code was working the previous day and now it doesn't, then I guess you must open MySQL CLI or MySQL Workbench and just make the connection to the database once. Once it gets connected, then the database also gets connected to the Java Application. I used to get the Hibernate Dialect error stating something wrong with com.mysql.jdbc.Driver. I think MySQL in some computers has a startup problem. This solved for me.
Today I face with the same issue, this is also providing another possibility. I did all suggestions above but still seeing the issue. I have no way but restart my mac.... Problem solved....
Only thing that worked for me is this function:
Sub DoTrim()
Dim cell As Range
Dim str As String
For Each cell In Selection.Cells
If cell.HasFormula = False Then
str = Left(cell.Value, 1) 'space
While str = " " Or str = Chr(160)
cell.Value = Right(cell.Value, Len(cell.Value) - 1)
str = Left(cell.Value, 1) 'space
Wend
str = Right(cell.Value, 1) 'space
While str = " " Or str = Chr(160)
cell.Value = Left(cell.Value, Len(cell.Value) - 1)
str = Right(cell.Value, 1) 'space
Wend
End If
Next cell
End Sub
As a best practice, especially if you have multiple date pickers, you should not hardcode the element's scope variable name.
Instead, you should get the clicked input's ng-model
and update its corresponding scope variable inside the onSelect
method.
app.directive('jqdatepicker', function() {
return {
restrict: 'A',
require: 'ngModel',
link: function(scope, element, attrs, ngModelCtrl) {
$(element).datepicker({
dateFormat: 'yy-mm-dd',
onSelect: function(date) {
var ngModelName = this.attributes['ng-model'].value;
// if value for the specified ngModel is a property of
// another object on the scope
if (ngModelName.indexOf(".") != -1) {
var objAttributes = ngModelName.split(".");
var lastAttribute = objAttributes.pop();
var partialObjString = objAttributes.join(".");
var partialObj = eval("scope." + partialObjString);
partialObj[lastAttribute] = date;
}
// if value for the specified ngModel is directly on the scope
else {
scope[ngModelName] = date;
}
scope.$apply();
}
});
}
};
});
EDIT
To address the issue that @Romain raised up (Nested Elements), I have modified my answer
This thread has some considerable debate about whether BN should be applied before non-linearity of current layer or to the activations of the previous layer.
Although there is no correct answer, the authors of Batch Normalization say that It should be applied immediately before the non-linearity of the current layer. The reason ( quoted from original paper) -
"We add the BN transform immediately before the nonlinearity, by normalizing x = Wu+b. We could have also normalized the layer inputs u, but since u is likely the output of another nonlinearity, the shape of its distribution is likely to change during training, and constraining its first and second moments would not eliminate the covariate shift. In contrast, Wu + b is more likely to have a symmetric, non-sparse distribution, that is “more Gaussian” (Hyv¨arinen & Oja, 2000); normalizing it is likely to produce activations with a stable distribution."
For auto resizing, try imagemagick... it is used for many major open source content/photo management systems... and I believe that there are some .net extensions for it.
Sometimes it is just easier to try something simple like this.
validateNumber(control: FormControl): { [s: string]: boolean } {
//revised to reflect null as an acceptable value
if (control.value === null) return null;
// check to see if the control value is no a number
if (isNaN(control.value)) {
return { 'NaN': true };
}
return null;
}
Hope this helps.
updated as per comment, You need to to call the validator like this
number: new FormControl('',[this.validateNumber.bind(this)])
The bind(this) is necessary if you are putting the validator in the component which is how I do it.
I was looking for the answer too and my intention was to clean every non-alpha and there shouldn't have more than one space.
So, I modified Alex's answer to this, and this is working for me
preg_replace('/[^a-z|\s+]+/i', ' ', $name)
The regex above turned sy8ed sirajul7_islam
to sy ed sirajul islam
Explanation: regex will check NOT ANY from a to z in case insensitive way or more than one white spaces, and it will be converted to a single space.
For closing cmd window, especially after ending weblogic or JBOSS app servers console with Ctrl+C, I'm using 'call
' command instead of 'start
' in my batch files. My startWLS.cmd file then looks like:
call [BEA_HOME]\user_projects\domains\test_domain\startWebLogic.cmd
After Ctrl+C(and 'Y' answer) cmd window is automatically closed.
I don't know why the other solutions go through the whole list of stylesheets for the document. Doing so creates a new entry in each stylesheet, which is inefficient. Instead, we can simply append a new stylesheet and simply add our desired CSS rules there.
style=document.createElement('style');
document.head.appendChild(style);
stylesheet=style.sheet;
function css(selector,property,value)
{
try{ stylesheet.insertRule(selector+' {'+property+':'+value+'}',stylesheet.cssRules.length); }
catch(err){}
}
Note that we can override even inline styles set directly on elements by adding " !important" to the value of the property, unless there already exist more specific "!important" style declarations for that property.
mkdirs()
will create the specified directory path in its entirety where mkdir()
will only create the bottom most directory, failing if it can't find the parent directory of the directory it is trying to create.
In other words mkdir()
is like mkdir
and mkdirs()
is like mkdir -p
.
For example, imagine we have an empty /tmp
directory. The following code
new File("/tmp/one/two/three").mkdirs();
would create the following directories:
/tmp/one
/tmp/one/two
/tmp/one/two/three
Where this code:
new File("/tmp/one/two/three").mkdir();
would not create any directories - as it wouldn't find /tmp/one/two
- and would return false
.
Here's what worked for me. My Python and Oracle versions are slightly different from yours, but the same approach should apply. Just make sure the cx_Oracle binary installer version matches your Oracle client and Python versions.
My versions:
Steps:

@echo off

conn_str = u'user/password@host:port/service'
conn = cx_Oracle.connect(conn_str)
c = conn.cursor()
c.execute(u'select your_col_1, your_col_2 from your_table')
for row in c:
print row[0], "-", row[1]
conn.close()

As I answered here, you can remove spines from all your plots through style settings (style sheet or rcParams):
import matplotlib as mpl
mpl.rcParams['axes.spines.left'] = False
mpl.rcParams['axes.spines.right'] = False
mpl.rcParams['axes.spines.top'] = False
mpl.rcParams['axes.spines.bottom'] = False
Probably svn import
would be the best option around. Check out Getting Data into Your Repository (in Version Control with Subversion, For Subversion).
The svn import command is a quick way to copy an unversioned tree of files into a repository, creating intermediate directories as necessary. svn import doesn't require a working copy, and your files are immediately committed to the repository. You typically use this when you have an existing tree of files that you want to begin tracking in your Subversion repository. For example:
$ svn import /path/to/mytree \ http://svn.example.com/svn/repo/some/project \ -m "Initial import" Adding mytree/foo.c Adding mytree/bar.c Adding mytree/subdir Adding mytree/subdir/quux.h Committed revision 1. $
The previous example copied the contents of the local directory mytree into the directory some/project in the repository. Note that you didn't have to create that new directory first—svn import does that for you. Immediately after the commit, you can see your data in the repository:
$ svn list http://svn.example.com/svn/repo/some/project bar.c foo.c subdir/ $
Note that after the import is finished, the original local directory is not converted into a working copy. To begin working on that data in a versioned fashion, you still need to create a fresh working copy of that tree.
Note: if you are on the same machine as the Subversion repository you can use the file://
specifier with a path rather than the https://
with a URL specifier.
Clone is broken, so dont use it.
THE CLONE METHOD of the Object class is a somewhat magical method that does what no pure Java method could ever do: It produces an identical copy of its object. It has been present in the primordial Object superclass since the Beta-release days of the Java compiler*; and it, like all ancient magic, requires the appropriate incantation to prevent the spell from unexpectedly backfiring
Prefer a method that copies the object
Foo copyFoo (Foo foo){
Foo f = new Foo();
//for all properties in FOo
f.set(foo.get());
return f;
}

If you have access to a console in the context you are investigating, you can determine which version you are running by printing the value of the global constant RUBY_VERSION
.
With PHP 7.4 I do it like this:
$ipaddress = '';
if (isset($_SERVER['REMOTE_ADDR']))
$ipaddress = $_SERVER['REMOTE_ADDR'];
else if(isset($_SERVER['HTTP_X_FORWARDED_FOR']))
$ipaddress = $_SERVER['HTTP_X_FORWARDED_FOR'];
else if(isset($_SERVER['HTTP_X_FORWARDED']))
$ipaddress = $_SERVER['HTTP_X_FORWARDED'];
else if(isset($_SERVER['HTTP_FORWARDED_FOR']))
$ipaddress = $_SERVER['HTTP_FORWARDED_FOR'];
else if(isset($_SERVER['HTTP_FORWARDED']))
$ipaddress = $_SERVER['HTTP_FORWARDED'];
else if(isset($_SERVER['HTTP_CLIENT_IP']))
$ipaddress = $_SERVER['HTTP_CLIENT_IP'];
But keep in mind that REMOTE_ADDR
is the only reliable IP address that you can get. All other values can easily be manipulated. This is theoretically also possible for REMOTE_ADDRESS
, but that would require to spoof the IP address.
In main.xml file
You can put the following attrubute to validate only alphabatics character can accept in edittext.
Do this :
android:entries="abcdefghijklmnopqrstuvwxyz"
I needed something to call scripts with named parameters. We have a policy of not using ordinal positioning of parameters and requiring the parameter name.
My approach is similar to the ones above but gets the content of the script file that you want to call and sends a parameter block containing the parameters and values.
One of the advantages of this is that you can optionally choose which parameters to send to the script file allowing for non-mandatory parameters with defaults.
Assuming there is a script called "MyScript.ps1" in the temporary path that has the following parameter block:
[CmdletBinding(PositionalBinding = $False)]
param
(
[Parameter(Mandatory = $True)] [String] $MyNamedParameter1,
[Parameter(Mandatory = $True)] [String] $MyNamedParameter2,
[Parameter(Mandatory = $False)] [String] $MyNamedParameter3 = "some default value"
)
This is how I would call this script from another script:
$params = @{
MyNamedParameter1 = $SomeValue
MyNamedParameter2 = $SomeOtherValue
}
If ($SomeCondition)
{
$params['MyNamedParameter3'] = $YetAnotherValue
}
$pathToScript = Join-Path -Path $env:Temp -ChildPath MyScript.ps1
$sb = [scriptblock]::create(".{$(Get-Content -Path $pathToScript -Raw)} $(&{
$args
} @params)")
Invoke-Command -ScriptBlock $sb
I have used this in lots of scenarios and it works really well. One thing that you occasionally need to do is put quotes around the parameter value assignment block. This is always the case when there are spaces in the value.
e.g. This param block is used to call a script that copies various modules into the standard location used by PowerShell C:\Program Files\WindowsPowerShell\Modules
which contains a space character.
$params = @{
SourcePath = "$WorkingDirectory\Modules"
DestinationPath = "'$(Join-Path -Path $([System.Environment]::GetFolderPath('ProgramFiles')) -ChildPath 'WindowsPowershell\Modules')'"
}

mysqldump will not dump database events, triggers and routines unless explicitly stated when dumping individual databases;
mysqldump -uuser -p db_name --events --triggers --routines > db_name.sql
Try this:
grep -rl 'SearchString' ./ | xargs sed -i 's/REPLACESTRING/WITHTHIS/g'
grep -rl
will recursively search for the SEARCHSTRING
in the directories ./
and will replace the strings using sed
.
Ex:
Replacing a name TOM
with JERRY
using search string as SWATKATS
in directory CARTOONNETWORK
grep -rl 'SWATKATS' CARTOONNETWORK/ | xargs sed -i 's/TOM/JERRY/g'
This will replace TOM
with JERRY
in all the files and subdirectories under CARTOONNETWORK
wherever it finds the string SWATKATS
.
You can try replacing this line:
return new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay);
By those:
DatePickerDialog dpDialog = new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay);
DatePicker datePicker = dpDialog.getDatePicker();
Calendar calendar = Calendar.getInstance();//get the current day
datePicker.setMaxDate(calendar.getTimeInMillis());//set the current day as the max date
return dpDialog;
try this
$ cmd='mysql AMORE -u root --password="password" -h localhost -e "select host from amoreconfig"'
$ eval $cmd
String.split uses Regular Expressions, also you don't need to allocate an extra array for your split.
The split-method will give you a list., the problem is that you try to pre-define how many occurrences you have of a tab, but how would you Really know that? Try using the Scanner or StringTokenizer and just learn how splitting strings work.
Let me explain Why \t does not work and why you need \\\\
to escape \\
.
Okay, so when you use Split, it actually takes a regex ( Regular Expression ) and in regular expression you want to define what Character to split by, and if you write \t that actually doesn't mean \t
and what you WANT to split by is \t
, right? So, by just writing \t
you tell your regex-processor that "Hey split by the character that is escaped t" NOT "Hey split by all characters looking like \t
". Notice the difference? Using \ means to escape something. And \
in regex means something Totally different than what you think.
So this is why you need to use this Solution:
\\t
To tell the regex processor to look for \t. Okay, so why would you need two of em? Well, the first \ escapes the second, which means it will look like this: \t when you are processing the text!
Now let's say that you are looking to split \
Well then you would be left with \\ but see, that doesn't Work! because \ will try to escape the previous char! That is why you want the Output to be \\ and therefore you need to have \\\\.
I really hope the examples above helps you understand why your solution doesn't work and how to conquer other ones!
Now, I've given you this answer before, maybe you should start looking at them now.
OTHER METHODS
StringTokenizer
You should look into the StringTokenizer, it's a very handy tool for this type of work.
Example
StringTokenizer st = new StringTokenizer("this is a test");
while (st.hasMoreTokens()) {
System.out.println(st.nextToken());
}
This will output
this
is
a
test
You use the Second Constructor for StringTokenizer to set the delimiter:
StringTokenizer(String str, String delim)
Scanner
You could also use a Scanner as one of the commentators said this could look somewhat like this
Example
String input = "1 fish 2 fish red fish blue fish";
Scanner s = new Scanner(input).useDelimiter("\\s*fish\\s*");
System.out.println(s.nextInt());
System.out.println(s.nextInt());
System.out.println(s.next());
System.out.println(s.next());
s.close();
The output would be
1
2
red
blue
Meaning that it will cut out the word "fish" and give you the rest, using "fish" as the delimiter.

The generic id points at a row in the table that was updated and the table name is the name of that table as a string. Not a good DB design, but very usable. All our tables have a single surrogate key column so this works well.
Totally agree with @Greg Hewgill
And if you path includes spaces, you might use, try adding with apostrophe '
or `
git diff 'MyProject/My Folder/My Sub Folder/file_2.rb'
JAXB Limitation.
I worked on JAXB, as per my opinion its a nice way of dealing with data between XML and Java objects. The Positive sides are its proven and better in performance and control over the data during runtime. With a good usage of built tools or scripts it will takes away lot of coding efforts.
I found the configuration part is not a straight away task, and spent hours in getting the development environment setup.
However I dropped this solution due to a silly limitation I faced. My XML Schema Definition ( XSD ) has a attribute/element with name "value" and that I have to use XSD as it is. This very little constraint forced the my binding step XJC failed with a Error "Property 'Value' already used."
This is due to the JAXB implementation, the binding process tries to create Java objects out of XSD by adding few attributes to each class and one of them being a value attribute. When it processed my XSD it complained that there is already a property with that name.
You didn't mention the fancy indexing capabilities of dataframes, e.g.:
>>> df = pd.DataFrame({"class":[1,1,1,2,2], "value":[1,2,3,4,5]})
>>> df[df["class"]==1].sum()
class 3
value 6
dtype: int64
>>> df[df["class"]==1].sum()["value"]
6
>>> df[df["class"]==1].count()["value"]
3
You could replace df["class"]==1
by another condition.
Because this captures all exceptions. It's unlikely that your program can recover from any of them.
You should handle only exceptions that you know how to recover from. If you don't anticipate a certain kind of exception, don't handle it, crash loudly (write details to the log), then diagnose logs and fix code.
Swallowing exceptions is bad, don't do this.
Since you have not mentioned what needs to be copied, I have left that section empty in the code below.
Also you don't need to move the email to the folder first and then run the macro in that folder. You can run the macro on the incoming mail and then move it to the folder at the same time.
This will get you started. I have commented the code so that you will not face any problem understanding it.
First paste the below mentioned code in the outlook module.
Then
When the new email arrives not only will the email move to the folder that you specify but data from it will be exported to Excel as well.

To extract the contents from your email body, you can split it using SPLIT() and then parsing out the relevant information from it. See this example
Dim MyAr() As String
MyAr = Split(olMail.body, vbCrLf)
For i = LBound(MyAr) To UBound(MyAr)
'~~> This will give you the contents of your email
'~~> on separate lines
Debug.Print MyAr(i)
Next i
The previous posters made a little mistake. The accept attribute is only a display filter. It will not validate your entry before submitting.
This attribute forces the file dialog to display the required mime type only. But the user can override that filter. He can choose . and see all the files in the current directory. By doing so, he can select any file with any extension, and submit the form.
So, to answer to the original poster, NO. You cannot restrict the input file to one particular extension by using HTML.
But you can use javascript to test the filename that has been chosen, just before submitting. Just insert an onclick attribute on your submit button and call the code that will test the input file value. If the extension is forbidden, you'll have to return false to invalidate the form. You may even use a jQuery custom validator and so on, to validate the form.
Finally, you'll have to test the extension on the server side too. Same problem about the maximum allowed file size.
To add disabled attribute
$('#id').attr("disabled", "true");
To remove Disabled Attribute
$('#id').removeAttr('disabled');
@eljenso : intrafest-servlet.xml webapplication context xml will be used if the application uses SPRING WEB MVC.
Otherwise the @kosoant configuration is fine.
Simple example if you dont use SPRING WEB MVC, but want to utitlize SPRING IOC :
In web.xml:
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:application-context.xml</param-value>
</context-param>
Then, your application-context.xml will contain: <import resource="foo-services.xml"/>
these import statements to load various application context files and put into main application-context.xml.
Thanks and hope this helps.
You can do it by setting the aspect of the image manually (or by letting it auto-scale to fill up the extent of the figure).
By default, imshow
sets the aspect of the plot to 1, as this is often what people want for image data.
In your case, you can do something like:
import matplotlib.pyplot as plt
import numpy as np
grid = np.random.random((10,10))
fig, (ax1, ax2, ax3) = plt.subplots(nrows=3, figsize=(6,10))
ax1.imshow(grid, extent=[0,100,0,1])
ax1.set_title('Default')
ax2.imshow(grid, extent=[0,100,0,1], aspect='auto')
ax2.set_title('Auto-scaled Aspect')
ax3.imshow(grid, extent=[0,100,0,1], aspect=100)
ax3.set_title('Manually Set Aspect')
plt.tight_layout()
plt.show()

Outside of character classes, it is conventional not to escape hyphens. If I saw an escaped hyphen outside of a character class, that would suggest to me that it was written by someone who was not very comfortable with regexes.
Inside character classes, I don't think one way is conventional over the other; in my experience, it usually seems to be to put either first or last, as in [-._:]
or [._:-]
, to avoid the backslash; but I've also often seen it escaped instead, as in [._\-:]
, and I wouldn't call that unconventional.
This Error can occur if the physical machine has run out of memory. In my case i was hosting a site on IIS trying to access the AD, but the server had run out of memory.
Right: it has nothing to do with your code. I've found two valid solutions to this warning (not just disabling it). To better understand what a SourceMap is, I suggest you check out this answer, where it explains how it's something that helps you debug:
The .map files are for js and css (and now ts too) files that have been minified. They are called SourceMaps. When you minify a file, like the angular.js file, it takes thousands of lines of pretty code and turns it into only a few lines of ugly code. Hopefully, when you are shipping your code to production, you are using the minified code instead of the full, unminified version. When your app is in production, and has an error, the sourcemap will help take your ugly file, and will allow you to see the original version of the code. If you didn't have the sourcemap, then any error would seem cryptic at best.
First solution: apparently, Mr Heelis was the closest one: you should add the .map file and there are some tools that help you with this problem (Grunt, Gulp and Google closure for example, quoting the answer). Otherwise you can download the .map file from official sites like Bootstrap, jquery, font-awesome, preload and so on.. (maybe installing things like popper or swiper by the npm command in a random folder and copying just the .map file in your js/css destination folder)
Second solution (the one I used): add the source files using a CDN (here all the advantages of using a CDN). Using the Content delivery network (CDN) you can simply add the cdn link, instead of the path to your folder. You can find cdn on official websites (Bootstrap, jquery, popper, etc..) or you can easily search on some websites like cloudflare, cdnjs, etc..
You need to do something like this:
// instantiate XmlDocument and load XML from file
XmlDocument doc = new XmlDocument();
doc.Load(@"D:\test.xml");
// get a list of nodes - in this case, I'm selecting all <AID> nodes under
// the <GroupAIDs> node - change to suit your needs
XmlNodeList aNodes = doc.SelectNodes("/Equipment/DataCollections/GroupAIDs/AID");
// loop through all AID nodes
foreach (XmlNode aNode in aNodes)
{
// grab the "id" attribute
XmlAttribute idAttribute = aNode.Attributes["id"];
// check if that attribute even exists...
if (idAttribute != null)
{
// if yes - read its current value
string currentValue = idAttribute.Value;
// here, you can now decide what to do - for demo purposes,
// I just set the ID value to a fixed value if it was empty before
if (string.IsNullOrEmpty(currentValue))
{
idAttribute.Value = "515";
}
}
}
// save the XmlDocument back to disk
doc.Save(@"D:\test2.xml");
As mentioned by @Brent in the comment of @maxymoo's answer, you can try
df.limit(10).toPandas()
to get a prettier table in Jupyter. But this can take some time to run if you are not caching the spark dataframe. Also, .limit()
will not keep the order of original spark dataframe.
Add a new class named as "Helper" and change the property of the class to "public static"
public static class Helper
{
public static List<T> DataTableToList<T>(this DataTable table) where T : class, new()

try
{
List<T> list = new List<T>();
foreach (var row in table.AsEnumerable())
{
T obj = new T();
foreach (var prop in obj.GetType().GetProperties())
{
try
{
PropertyInfo propertyInfo = obj.GetType().GetProperty(prop.Name);
propertyInfo.SetValue(obj, Convert.ChangeType(row[prop.Name], propertyInfo.PropertyType), null);
}
catch
{
continue;
}
}
list.Add(obj);
}
return list;
}
catch
{
return null;
}
}
}
and access this class in your code behind as like below
DataTable dtt = dsCallList.Tables[0];
List<CallAssignment> lstCallAssignement = dtt.DataTableToList<CallAssignment>();

There is a simple why that I prefered to the bundle due to the no duplicate data in memory. It consists of a init public method for the fragment
private ArrayList<Music> listMusics = new ArrayList<Music>();
private ListView listMusic;
public static ListMusicFragment createInstance(List<Music> music) {
ListMusicFragment fragment = new ListMusicFragment();
fragment.init(music);
return fragment;
}
public void init(List<Music> music){
this.listMusic = music;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
View view = inflater.inflate(R.layout.musiclistview, container, false);
listMusic = (ListView) view.findViewById(R.id.musicListView);
listMusic.setAdapter(new MusicBaseAdapter(getActivity(), listMusics));
return view;
}
}
In two words, you create an instance of the fragment an by the init method (u can call it as u want) you pass the reference of your list without create a copy by serialization to the instance of the fragment. This is very usefull because if you change something in the list u will get it in the other parts of the app and ofcourse, you use less memory.
When using the saveas function the resolution isn't as good as when manually saving the figure with File-->Save As..., It's more recommended to use hgexport instead, as follows:
hgexport(gcf, 'figure1.jpg', hgexport('factorystyle'), 'Format', 'jpeg');
This will do exactly as manually saving the figure.

Interesting. How are you generating your JSON on the server end? Are you using a library function (such as json_encode
in PHP), or are you building the JSON string by hand?
The only thing that grabs my attention is the escape apostrophe (\'
). Seeing as you're using double quotes, as you indeed should, there is no need to escape single quotes. I can't check if that is indeed the cause for your jQuery error, as I haven't updated to version 1.4.1 myself yet.
I was actually wondering this today, and I achieved it by using the php explode function, like this:
HTML Form (in a file I named 'doublevalue.php':
<form name="car_form" method="post" action="doublevalue_action.php">
<select name="car" id="car">
<option value="">Select Car</option>
<option value="BMW|Red">Red BMW</option>
<option value="Mercedes|Black">Black Mercedes</option>
</select>
<input type="submit" name="submit" id="submit" value="submit">
</form>
PHP action (in a file I named doublevalue_action.php)
<?php
$result = $_POST['car'];
$result_explode = explode('|', $result);
echo "Model: ". $result_explode[0]."<br />";
echo "Colour: ". $result_explode[1]."<br />";
?>
As you can see in the first piece of code, we're creating a standard HTML select box, with 2 options. Each option has 1 value, which has a separator (in this instance, '|') to split the values (in this case, model and colour).
On the action page, I'm exploding the results into an array, then calling each one. As you can see, I've separated and labelled them so you can see the effect this is causing.
I hope this helps someone :)
You use it like this:
SELECT age, name
FROM users
UNION
SELECT 25 AS age, 'Betty' AS name
Use UNION ALL
to allow duplicates: if there is a 25-years old Betty among your users, the second query will not select her again with mere UNION
.
It's also possible that you have accidentally put the IDE into Full Screen Mode
. On occasion, you may be inadertently pressing F11 to set FullScreen mode to On.
If this is the case, the Accepted Answer above will not work. Instead, you must disable Full Screen mode (View > Appearance > Full Screen).
Please see the attached screenshot.
select * from your_table where your_field like '%a%b%'
and be prepared to wait a while...
Edit: note that this pattern looks for an 'a' followed by a 'b' (possibly with other "stuff" in between) -- rereading your question, that may not be what you wanted...

Implement toString() on the class.
I recommend the Apache Commons ToStringBuilder to make this easier. With it, you just have to write this sort of method:
public String toString() {
return new ToStringBuilder(this).
append("name", name).
append("age", age).
toString();
}
In order to get this sort of output:
Person@7f54[name=Stephen,age=29]
There is also a reflective implementation.
If you are trying to do something similar to the Google search page when open in Chrome, (where certain events are triggered when you 'focus' on the page), then the hover() event may help.
$(window).hover(function() {
// code here...

I've used Xavier's answer quite a bit. I want to add that restricting the package version to a specified range is easy and useful in the latest versions of NuGet.
For example, if you never want Newtonsoft.Json
to be updated past version 3.x.x
in your project, change the corresponding package
element in your packages.config
file to look like this:
<package id="Newtonsoft.Json" version="3.5.8" allowedVersions="[3.0, 4.0)" targetFramework="net40" />
Notice the allowedVersions
attribute. This will limit the version of that package to versions between 3.0
(inclusive) and 4.0
(exclusive). Then, when you do an Update-Package
on the whole solution, you don't need to worry about that particular package being updated past version 3.x.x
.
The documentation for this functionality is here.
