None of the answers above, at least to me, show how to actually handle determining whether you have 1 item or multiple, and how to actually get the values out of your items in a generic way that doesn't depend on there actually only being one item, or multiple, so I'm throwing my hat in the ring.
This is quite easily and generically done by checking your count to see that you have at least one item, then doing a foreach
loop on the .SelectedItems
, casting each item as a DataRowView
:
if (listView1.SelectedItems.Count > 0)
{
foreach (DataRowView drv in listView1.SelectedItems)
{
string firstColumn = drv.Row[0] != null ? drv.Row[0].ToString() : String.Empty;
string secondColumn = drv.Row[1] != null ? drv.Row[1].ToString() : String.Empty;
// ... do something with these values before they are replaced
// by the next run of the loop that will get the next row
}
}
This will work, whether you have 1 item or many. It's funny that MSDN says to use ListView.SelectedListViewItemCollection
to capture listView1.SelectedItems
and iterate through that, but I found that this gave an error in my WPF app: The type name 'SelectedListViewItemCollection' does not exist in type 'ListView'
.
To the top voted answer. I prefer passing by rvalue reference.
I understand what's the problem about passing by rvalue reference may cause. But let's divide this problem to two sides:
I must write code Base newBase(std::move(<lvalue>))
or Base newBase(<rvalue>)
.
Library author should guarantee it will actually move the unique_ptr to initialize member if it want own the ownership.
That's all.
If you pass by rvalue reference, it will only invoke one "move" instruction, but if pass by value, it's two.
Yep, if library author is not expert about this, he may not move unique_ptr to initialize member, but it's the problem of author, not you. Whatever it pass by value or rvalue reference, your code is same!
If you are writing a library, now you know you should guarantee it, so just do it, passing by rvalue reference is a better choice than value. Client who use you library will just write same code.
Now, for your question. How do I pass a unique_ptr argument to a constructor or a function?
You know what's the best choice.

PS here you may find a bit more generic solution
UPDATE: some explanations: IMO the easiest way to understand this code is to try to execute it step-by-step:
in the following line we are repeating values in one column N
times where N
- is the length of the corresponding list:
In [10]: np.repeat(df['trial_num'].values, df[lst_col].str.len())
Out[10]: array([1, 1, 1, 2, 2, 2, 3, 3, 3, 1, 1, 1, 2, 2, 2, 3, 3, 3], dtype=int64)
this can be generalized for all columns, containing scalar values:
In [11]: pd.DataFrame({
...: col:np.repeat(df[col].values, df[lst_col].str.len())
...: for col in df.columns.drop(lst_col)}
...: )
Out[11]:
trial_num subject
0 1 1
1 1 1
2 1 1
3 2 1
4 2 1
5 2 1
6 3 1

11 1 2
12 2 2
13 2 2
14 2 2
15 3 2
16 3 2
17 3 2
[18 rows x 2 columns]
using np.concatenate()
we can flatten all values in the list
column (samples
) and get a 1D vector:
In [12]: np.concatenate(df[lst_col].values)
Out[12]: array([-1.04, -0.58, -1.32, 0.82, -0.59, -0.34, 0.25, 2.09, 0.12, 0.83, -0.88, 0.68, 0.55, -0.56, 0.65, -0.04, 0.36, -0.31])
putting all this together:
In [13]: pd.DataFrame({
...: col:np.repeat(df[col].values, df[lst_col].str.len())
...: for col in df.columns.drop(lst_col)}
...: ).assign(**{lst_col:np.concatenate(df[lst_col].values)})
Out[13]:
trial_num subject samples
0 1 1 -1.04

16 3 2 0.36
17 3 2 -0.31
[18 rows x 3 columns]
using pd.DataFrame()[df.columns]
will guarantee that we are selecting columns in the original order...
Use like this!
interface Iinput {
label: string
placeholder: string
register: any
type?: string
required: boolean
}
// This is how it can be done
const inputs: Array<Iinput> = [
{
label: "Title",
placeholder: "Bought something",
register: register,
required: true,
},
]
There was same problem in my Colleague's code. This sounds as your Radio Group is not properly set with your Radio Buttons. This is the reason you can multi-select the radio buttons. I tried many things, finally i did a trick which is wrong actually, but works fine.
for ( int i = 0 ; i < myCount ; i++ )
{
if ( i != k )
{
System.out.println ( "i = " + i );
radio1[i].setChecked(false);
}
}
Here I set one for loop, which checks for the available radio buttons and de-selects every one except the new clicked one. try it.
This is probably the easiest way:
new Date(<your-date-object>.toDateString());
Example: To get the Current Date without time component:
new Date(new Date().toDateString());
gives: Thu Jul 11 2019 00:00:00 GMT-0400 (Eastern Daylight Time)
Note this works universally, because toDateString()
produces date string with your browser's localization (without the time component), and the new Date()
uses the same localization to parse that date string.
I ran into this problem with a custom web client. I think people may be getting confused because of multiple ways to do this. When using WebRequest.Create()
you can cast to an HttpWebRequest
and use the property to add or modify a header. When using a WebHeaderCollection
you may use the .Add("referer","my_url")
.
Ex 1
WebClient client = new WebClient();
client.Headers.Add("referer", "http://stackoverflow.com");
client.Headers.Add("user-agent", "Mozilla/5.0");
Ex 2
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Referer = "http://stackoverflow.com";
request.UserAgent = "Mozilla/5.0";
response = (HttpWebResponse)request.GetResponse();
This will match one or more alphabetical characters:
/^[a-z]+$/
You can make it case insensitive using:
/^[a-z]+$/i
or:
/^[a-zA-Z]+$/
I just ran into this problem myself.
The fix I come out with was to go to the organizer, click on the "provisioning profiles" tab, and press refresh in the low corner.

Move excel variables which are global declare in your form to local like in my form I have:
Dim xls As New MyExcel.Interop.Application
Dim xlb As MyExcel.Interop.Workbook
above two lines were declare global in my form so i moved these two lines to local function and now tool is working fine.
In Select2 version 4 each option has the same properties of the objects in the list;
if you have the object
Obj = {
name: "Alberas",
description: "developer",
birthDate: "01/01/1990"
}
then you retrieve the selected data
var data = $('#id-selected-input').select2('data');
console.log(data[0].name);
console.log(data[0].description);
console.log(data[0].birthDate);
Considering if you haven't committed your changes in a while, maybe doing this will work for you.
git add files
git commit -m "Your Commit"
git push -u origin master
That worked for me, hopefully it does for you too.
Note: This answer is from 2011. However, it is still valid.
You can use Connect and ServeStatic with Node.js for this:
Install connect and serve-static with NPM
$ npm install connect serve-static
Create server.js file with this content:
var connect = require('connect');
var serveStatic = require('serve-static');
connect()
.use(serveStatic(__dirname))
.listen(8080, () => console.log('Server running on 8080...'));
Run with Node.js
$ node server.js
You can now go to http://localhost:8080/yourfile.html
I tried several of the suggestions above and unfortunately none of them worked. We have a "Log" index in our lower environment where apps write their errors. It is a single node cluster. What solved it for me was checking the YML configuration file for the node and seeing that it still had the default setting "gateway.expected_nodes: 2". This was overriding any other settings we had. Whenever we would create an index on this node it would try to spread 3 out of 5 shards to the phantom 2nd node. These would therefore appear as unassigned and they could never be moved to the 1st and only node.
The solution was editing the config, changing the setting "gateway.expected_nodes" to 1, so it would quit looking for its never-to-be-found brother in the cluster, and restarting the Elastic service instance. Also, I had to delete the index, and create a new one. After creating the index, the shards all showed up on the 1st and only node, and none were unassigned.
# Set how many nodes are expected in this cluster. Once these N nodes
# are up (and recover_after_nodes is met), begin recovery process immediately
# (without waiting for recover_after_time to expire):
#
# gateway.expected_nodes: 2
gateway.expected_nodes: 1
The NULL
part is calculated AFTER the actual join, so that is why it needs to be in the where clause.
You need to use the document.getElementsByClassName('class_name');
and dont forget that the returned value is an array of elements so if you want the first one use:
document.getElementsByClassName('class_name')[0]
UPDATE
Now you can use:
document.querySelector(".class_name")
to get the first element with the class_name
CSS class (null
will be returned if non of the elements on the page has this class name)
or document.querySelectorAll(".class_name")
to get a NodeList of elements with the class_name
css class (empty NodeList will be returned if non of. the elements on the the page has this class name).
More generally, generating a random integer with fixed length can be done using Math.pow
:
var randomFixedInteger = function (length) {
return Math.floor(Math.pow(10, length-1) + Math.random() * (Math.pow(10, length) - Math.pow(10, length-1) - 1));
}
To answer the question: randomFixedInteger(6);
REST is somewhat of a revival of old-school HTTP, where the actual HTTP verbs (commands) have semantic meaning. Til recently, apps that wanted to update stuff on the server would supply a form containing an 'action' variable and a bunch of data. The HTTP command would almost always be GET
or POST
, and would be almost irrelevant. (Though there's almost always been a proscription against using GET for operations that have side effects, in reality a lot of apps don't care about the command used.)
With REST, you might instead PUT /profiles/cHao
and send an XML or JSON representation of the profile info. (Or rather, I would -- you would have to update your own profile. :) That'd involve logging in, usually through HTTP's built-in authentication mechanisms.) In the latter case, what you want to do is specified by the URL, and the request body is just the guts of the resource involved.
http://en.wikipedia.org/wiki/Representational_State_Transfer has some details.

It seemed that a lot of dependencies were incorrect.
A good place to look for the correct dependencies is the Maven Repository website.
$ su - postgres

select the user that do you want be superuser and:
$ ALTER USER "user" with superuser;
In python3, __init__.py
is no longer necessary. If the current directory of the console is the directory where the python script is located, everything works fine with
import user
However, this won't work if called from a different directory, which does not contain user.py
.
In that case, use
from . import user
This works even if you want to import the whole file instead of just a class from there.

int k = 0; // Counter for mergedList
while (true) {
if (i >= listA.length && j >= listB.length) {
break;
}
if (i < listA.length && j < listB.length) { // If both counters are valid.
if (listA[i] <= listB[j]) {
mergedList[k] = listA[i];
k++;
i++;
} else {
mergedList[k] = listB[j];
k++;

mergedList[k] = listA[i];
k++;
i++;
} else if (i <= listA.length && j < listB.length) { // If only B's counter is valid
mergedList[k] = listB[j];
k++;

}
}
return mergedList;

If you want "Use Autolayout" to be enabled at any cost place the following code in viewdidload.

self.extendedLayoutIncludesOpaqueBars = NO;
self.automaticallyAdjustsScrollViewInsets = NO;

Meridian pertains to AM/PM, by setting it to false you're indicating you don't want AM/PM, therefore you want 24-hour clock implicitly.
$('#timepicker1').timepicker({showMeridian:false});
The hint is, the output file is created even if you get this error. The automatic deconstruction of vector starts after your code executed. Elements in the vector are deconstructed as well. This is most probably where the error occurs. The way you access the vector is through vector::operator[]
with an index read from stream. Try vector::at()
instead of vector::operator[]
. This won't solve your problem, but will show which assignment to the vector causes error.

head
works too:
head -c 100 file # returns the first 100 bytes in the file
..will extract the first 100 bytes and return them.
What's nice about using head
for this is that the syntax for tail
matches:
tail -c 100 file # returns the last 100 bytes in the file
You can combine these to get ranges of bytes. For example, to get the second 100 bytes from a file, read the first 200 with head
and use tail to get the last 100:
head -c 200 file | tail -c 100
An alternative to Trikaldarshi's one line solution. (It avoids having to construct FileInfo objects)
long sizeInBytes = Directory.EnumerateFiles("{path}","*", SearchOption.AllDirectories).Sum(fileInfo => new FileInfo(fileInfo).Length);
Instead of breaking it down into individual fields, it's easier to generate a random block of data and change the individual byte positions. You should also use a better random number generator than mt_rand().
According to RFC 4122 - Section 4.4, you need to change these fields:
time_hi_and_version
(bits 4-7 of 7th octet),clock_seq_hi_and_reserved
(bit 6 & 7 of 9th octet)All of the other 122 bits should be sufficiently random.
The following approach generates 128 bits of random data using openssl_random_pseudo_bytes()
, makes the permutations on the octets and then uses bin2hex()
and vsprintf()
to do the final formatting.
function guidv4($data)
{
assert(strlen($data) == 16);
$data[6] = chr(ord($data[6]) & 0x0f | 0x40); // set version to 0100
$data[8] = chr(ord($data[8]) & 0x3f | 0x80); // set bits 6-7 to 10
return vsprintf('%s%s-%s-%s-%s-%s%s%s', str_split(bin2hex($data), 4));
}
echo guidv4(openssl_random_pseudo_bytes(16));
With PHP 7, generating random byte sequences is even simpler using random_bytes()
:
function guidv4($data = null)
{
$data = $data ?? random_bytes(16);
// ...
}
Job Import plugin is the easy way here to import jobs from another Jenkins instance. Just need to provide the URL of the source Jenkins instance. The Remote Jenkins URL can take any of the following types of URLs:
http://$JENKINS
- get all jobs on remote instance
http://$JENKINS/job/$JOBNAME
- get a single job
http://$JENKINS/view/$VIEWNAME
- get all jobs in a particular view

Visibility change itself can be easy animated by overriding setVisibility method. Look at complete code:

}
public void setInAnimation(Animation inAnimation)
{

public void setOutAnimation(Animation outAnimation)
{
this.outAnimation = outAnimation;
}
@Override
public void setVisibility(int visibility)
{
if (getVisibility() != visibility)
{
if (visibility == VISIBLE)
{
if (inAnimation != null) startAnimation(inAnimation);
}
else if ((visibility == INVISIBLE) || (visibility == GONE))
{
if (outAnimation != null) startAnimation(outAnimation);
}
}
super.setVisibility(visibility);

Turns out that the post (or rather the whole table) was locked by the very same connection that I tried to update the post with.
I had a opened record set of the post that was created by:
Set RecSet = Conn.Execute()
This type of recordset is supposed to be read-only and when I was using MS Access as database it did not lock anything. But apparently this type of record set did lock something on MS SQL Server 2012 because when I added these lines of code before executing the UPDATE SQL statement...
RecSet.Close
Set RecSet = Nothing
...everything worked just fine.
So bottom line is to be careful with opened record sets - even if they are read-only they could lock your table from updates.
A somewhat better solution:

int main(int argc, char** argv) {
if (IsDebuggerPresent())
atexit([] {system("PAUSE"); });

I like the "list" example, but "list" only works on the left-hand-side of an assignment. If we don't want to assign a variable, we would be forced to make up a temporary name, which at best pollutes our scope and at worst overwrites an existing value:
list($x) = some_array();
var_dump($x);
The above will overwrite any existing value of $x, and the $x variable will hang around as long as this scope is active (the end of this function/method, or forever if we're in the top-level). This can be worked around using call_user_func and an anonymous function, but it's clunky:
var_dump(call_user_func(function($arr) { list($x) = $arr; return $x; },
some_array()));
If we use anonymous functions like this, we can actually get away with reset and array_shift, even though they use pass-by-reference. This is because calling a function will bind its arguments, and these arguments can be passed by reference:
var_dump(call_user_func(function($arr) { return reset($arr); },
array_values(some_array())));
However, this is actually overkill, since call_user_func will perform this temporary assignment internally. This lets us treat pass-by-reference functions as if they were pass-by-value, without any warnings or errors:
var_dump(call_user_func('reset', array_values(some_array())));
You are missing a parantheses in the denominator of your gaussian() function. As it is right now you divide by 2 and multiply with the variance (sig^2). But that is not true and as you can see of your plots the greater variance the more narrow the gaussian is - which is wrong, it should be opposit.
So just change the gaussian() function to:
def gaussian(x, mu, sig):
return np.exp(-np.power(x - mu, 2.) / (2 * np.power(sig, 2.)))

The reason is, spring boot comes with logback as its default log configuration whereas camel uses log4j. Thats the reason of conflict. You have two options, either remove logback from spring boot as mentioned in above answers or remove log4j from camel.

I'll throw RxJava in the ring, which is also available on Android. RxJava might not always be the best option, but it will give you more flexibility if you wish add more transformations on your collection or handle errors while filtering.
Observable.from(Arrays.asList(1, 2, 3, 4, 5))
.filter(new Func1<Integer, Boolean>() {
public Boolean call(Integer i) {
return i % 2 != 0;
}
})
.subscribe(new Action1<Integer>() {
public void call(Integer i) {
System.out.println(i);
}
});
Output:

High-Level Design (HLD) involves decomposing a system into modules, and representing the interfaces & invocation relationships among modules. An HLD is referred to as software architecture.
LLD, also known as a detailed design, is used to design internals of the individual modules identified during HLD i.e. data structures and algorithms of the modules are designed and documented.
Now, HLD and LLD are actually used in traditional Approach (Function-Oriented Software Design) whereas, in OOAD, the system is seen as a set of objects interacting with each other.
As per the above definitions, a high-level design document will usually include a high-level architecture diagram depicting the components, interfaces, and networks that need to be further specified or developed. The document may also depict or otherwise refer to work flows and/or data flows between component systems.
Class diagrams with all the methods and relations between classes come under LLD. Program specs are covered under LLD. LLD describes each and every module in an elaborate manner so that the programmer can directly code the program based on it. There will be at least 1 document for each module. The LLD will contain - a detailed functional logic of the module in pseudo code - database tables with all elements including their type and size - all interface details with complete API references(both requests and responses) - all dependency issues - error message listings - complete inputs and outputs for a module.
I recommend the following syntax for readability.
<? if ($condition): ?>
<p>Content</p>
<? elseif ($other_condition): ?>
<p>Other Content</p>
<? else: ?>
<p>Default Content</p>
<? endif; ?>
Note, omitting php
on the open tags does require that short_open_tags
is enabled in your configuration, which is the default. The relevant curly-brace-free conditional syntax is always enabled and can be used regardless of this directive.

Been having this error all day. I finally fixed it by going to Tools>Import and Export Settings> Reset all options > Reset General Settings.
Once it's reset go to Tools>Options>Debugging>Symbols> -- Then Check the box next to Microsoft Symbol Servers.
Run your app in debug mode, and it will open up windows saying it's downloading Symbols for a bunch of different .dll files. Let it finish doing this.
Once it completes, it should work again.
XML is not a format for storing images, neither binary data. I think it all depends on how you want to use those images. If you are in a web application and would want to read them from there and display them, I would store the URLs. If you need to send them to another web endpoint, I would serialize them, rather than persisting manually in XML. Please explain what is the scenario.
Instead of using string interpolation you could simply format the DateTime using the ToString("u")
method and concatenate that with the rest of the string:
$startTime = Get-Date
Write-Host "The script was started " + $startTime.ToString("u")
It is very clear from your exception that it is trying to connect to localhost
and not to 10.101.3.229
exception snippet : Could not connect to SMTP host: localhost, port: 25;
1.) Please check if there are any null check which is setting localhost as default value
2.) After restarting, if it is working fine, then it means that only at first-run, the proper value is been taken from Properties and from next run the value is set to default. So keep the property-object as a singleton one and use it all-over your project
If you can't go over your time limit (it's a hard limit) then a thread is your best bet. You can use a loop to terminate the thread once you get to the time threshold. Whatever is going on in that thread at the time can be interrupted, allowing calculations to stop almost instantly. Here is an example:
Thread t = new Thread(myRunnable); // myRunnable does your calculations
long startTime = System.currentTimeMillis();
long endTime = startTime + 60000L;
t.start(); // Kick off calculations
while (System.currentTimeMillis() < endTime) {
// Still within time theshold, wait a little longer
try {
Thread.sleep(500L); // Sleep 1/2 second
} catch (InterruptedException e) {
// Someone woke us up during sleep, that's OK
}
}
t.interrupt(); // Tell the thread to stop
t.join(); // Wait for the thread to cleanup and finish
That will give you resolution to about 1/2 second. By polling more often in the while loop, you can get that down.
Your runnable's run would look something like this:
public void run() {
while (true) {
try {
// Long running work
calculateMassOfUniverse();
} catch (InterruptedException e) {
// We were signaled, clean things up
cleanupStuff();
break; // Leave the loop, thread will exit
}
}
Update based on Dmitri's answer
Dmitri pointed out TimerTask, which would let you avoid the loop. You could just do the join call and the TimerTask you setup would take care of interrupting the thread. This would let you get more exact resolution without having to poll in a loop.
No criticism regarding those great answers I just want to present the simple solution I use for our admin content creators:
^(\+|00)[1-9][0-9 \-\(\)\.]{7,}$
Force start with a plus or two zeros and use at least a little bit of numbers, white space, braces, minus and point is optional and no other characters. You can safely remove all non-numbers and use this in a tel: input. Numbers will have a common form of representation and I do not have to worry about being to restrictive.
Another variant:
private String getCharForNumber(int i) {
if (i > 25 || i < 0) {
return null;
}
return new Character((char) (i + 65)).toString();
}
Highlight the cell, use Dat => Text to Columns and the DELIMITER is space. Result will appear in as many columns as the split find the space.
At each point in these instructions, check to see if the problem is fixed. If so, great! Otherwise, continue.

There are 2 options to find matching text; string.match
or string.find
.
Both of these perform a regex search on the string to find matches.
string.find()
string.find(subject string, pattern string, optional start position, optional plain flag)
Returns the startIndex
& endIndex
of the substring found.
The plain
flag allows for the pattern to be ignored and intead be interpreted as a literal. Rather than (tiger)
being interpreted as a regex capture group matching for tiger
, it instead looks for (tiger)
within a string.
Going the other way, if you want to regex match but still want literal special characters (such as .()[]+-
etc.), you can escape them with a percentage; %(tiger%)
.
You will likely use this in combination with string.sub
str = "This is some text containing the word tiger."
if string.find(str, "tiger") then
print ("The word tiger was found.")
else
print ("The word tiger was not found.")
end
string.match()
string.match(s, pattern, optional index)
Returns the capture groups found.
str = "This is some text containing the word tiger."
if string.match(str, "tiger") then
print ("The word tiger was found.")
else
print ("The word tiger was not found.")
end
Try the below code, you need not specify the schema. When you give inferSchema as true it should take it from your csv file.
val pagecount = sqlContext.read.format("csv")
.option("delimiter"," ").option("quote","")
.option("header", "true")
.option("inferSchema", "true")
.load("dbfs:/databricks-datasets/wikipedia-datasets/data-001/pagecounts/sample/pagecounts-20151124-170000")
If you want to manually specify the schema, you can do it as below:
import org.apache.spark.sql.types._
val customSchema = StructType(Array(
StructField("project", StringType, true),
StructField("article", StringType, true),
StructField("requests", IntegerType, true),
StructField("bytes_served", DoubleType, true))
)
val pagecount = sqlContext.read.format("csv")
.option("delimiter"," ").option("quote","")
.option("header", "true")
.schema(customSchema)
.load("dbfs:/databricks-datasets/wikipedia-datasets/data-001/pagecounts/sample/pagecounts-20151124-170000")
On Raspberry pi II, I had the same problem. After trying the following, I solved the problem. The solution is:
sudo apt-get update
sudo apt-get install libjpeg-dev
In C++, variable length arrays are not legal. G++ allows this as an "extension" (because C allows it), so in G++ (without being -pedantic
about following the C++ standard), you can do:
int n = 10;
double a[n]; // Legal in g++ (with extensions), illegal in proper C++
If you want a "variable length array" (better called a "dynamically sized array" in C++, since proper variable length arrays aren't allowed), you either have to dynamically allocate memory yourself:
int n = 10;
double* a = new double[n]; // Don't forget to delete [] a; when you're done!
Or, better yet, use a standard container:
int n = 10;
std::vector<double> a(n); // Don't forget to #include <vector>
If you still want a proper array, you can use a constant, not a variable, when creating it:
const int n = 10;
double a[n]; // now valid, since n isn't a variable (it's a compile time constant)
Similarly, if you want to get the size from a function in C++11, you can use a constexpr
:
constexpr int n()
{
return 10;
}
double a[n()]; // n() is a compile time constant expression
void foo<TOne, TTwo>()
where TOne : BaseOne
where TTwo : BaseTwo

My Spring boot application has two initializers. One for development and another for production. For development, I use the main method like this:
@SpringBootApplication
public class MyAppInitializer {
public static void main(String[] args) {
SpringApplication.run(MyAppInitializer .class, args);
}
}
My Initializer for production environment extends the SpringBootServletInitializer and looks like this:
@SpringBootApplication
public class MyAppInitializerServlet extends SpringBootServletInitializer{
private static final Logger log = Logger
.getLogger(SpringBootServletInitializer.class);
@Override
protected SpringApplicationBuilder configure(
SpringApplicationBuilder builder) {
log.trace("Initializing the application");
return builder.sources(MyAppInitializerServlet .class);
}
}
I use gradle and my build.gradle file applies 'WAR' plugin. When I run it in the development environment, I use bootrun task. Where as when I want to deploy it to production, I use assemble task to generate the WAR and deploy.
I can run like a normal spring application in production without discounting the advantages provided by the inbuilt tomcat while developing. Hope this helps.
I used the second solution of user147767
However, there is a typo here. It should be
curCssName.toUpperCase().indexOf(cssName.toUpperCase() + ':') < 0
not <= 0
I also changed this condition for:
!curCssName.match(new RegExp(cssName + "(-.+)?:"), "mi")
as sometimes we add a css property over jQuery, and it's added in a different way for different browsers (i.e. the border property will be added as "border" for Firefox, and "border-top", "border-bottom" etc for IE).
Prepending a BOM (\uFEFF) worked for me (Excel 2007), in that Excel recognised the file as UTF-8. Otherwise, saving it and using the import wizard works, but is less ideal.
2017 Update: Henry's answer may be a little off the mark here. If you look for data-channel-external-id
in the source code you may find more than one ID, and only the first occurrence is actually correct. Get the channel_id
used in <link rel="alternate" type="application/rss+xml" title="RSS" href="https://www.youtube.com/feeds/videos.xml?channel_id=<VALUE_HERE">
instead.
I'm using Windows 10. The following updates everything and also installs some new packages, including a Python update (for me it was 3.7.3).
At the shell, try the following (be sure to change where your Anaconda 3 Data is installed). It takes some time to update everything.
conda update --prefix X:\XXXXData\Anaconda3 anaconda
In addition to the other answers, here is another useful approach for hiding text.
This method effectively hides the text, yet allows it to remain visible for screen readers. This is an option to consider if accessibility is a concern.
.sr-only {
position: absolute;
width: 1px;
height: 1px;
padding: 0;
margin: -1px;
overflow: hidden;
clip: rect(0,0,0,0);
border: 0;
}
It's worth pointing out that this class is currently used in Bootstrap 3.
If you're interested in reading about accessibility:
This question showed up when I was searching for a fast way to use git builtin way to locate differences. My solution criteria:
I found this answer to get color in git.
To get side by side diff instead of line diff I tweaked mb14's excellent answer on this question with the following parameters:
$ git diff --word-diff-regex="[A-Za-z0-9. ]|[^[:space:]]"
If you do not like the extra [- or {+ the option --word-diff=color
can be used.
$ git diff --word-diff-regex="[A-Za-z0-9. ]|[^[:space:]]" --word-diff=color
That helped to get proper comparison with both json and xml text and java code.
In summary the --word-diff-regex
options has a helpful visibility together with color settings to get a colorized side by side source code experience compared to the standard line diff, when browsing through big files with small line changes.
I wanted a way to do this without using an extra module. First turn list to string, then append to an array:
dataset_list = ''.join(input_list)
dataset_array = []
for item in dataset_list.split(';'): # comma, or other
dataset_array.append(item)
You haven't put the shared library in a location where the loader can find it. look inside the /usr/local/opencv
and /usr/local/opencv2
folders and see if either of them contains any shared libraries (files beginning in lib
and usually ending in .so
). when you find them, create a file called /etc/ld.so.conf.d/opencv.conf
and write to it the paths to the folders where the libraries are stored, one per line.
for example, if the libraries were stored under /usr/local/opencv/libopencv_core.so.2.4
then I would write this to my opencv.conf
file:
/usr/local/opencv/
Then run
sudo ldconfig -v
If you can't find the libraries, try running
sudo updatedb && locate libopencv_core.so.2.4
in a shell. You don't need to run updatedb
if you've rebooted since compiling OpenCV.

It's hard to say what your question is, but there are some alternatives.
If you mean to literally execute a request using the ICMP ping protocol, you can get an ICMP library and execute the ping request directly. Google "Python ICMP" to find things like this icmplib. You might want to look at scapy, also.
This will be much faster than using os.system("ping " + ip )
.
If you mean to generically "ping" a box to see if it's up, you can use the echo protocol on port 7.
For echo, you use the socket library to open the IP address and port 7. You write something on that port, send a carriage return ("\r\n"
) and then read the reply.
If you mean to "ping" a web site to see if the site is running, you have to use the http protocol on port 80.
For or properly checking a web server, you use urllib2 to open a specific URL. (/index.html
is always popular) and read the response.
There are still more potential meaning of "ping" including "traceroute" and "finger".

Based on @brettdj's answer using a VBScript regex ojbect with two modifications:
Function GetDigitsInVariant(inputVariant As Variant) As Variant
' Returns:

' GetDigitsInVariant(2021-05-18) => 20210518
' Notes:
' If the inputVariant is null, null will be returned.
' If the inputVariant is "", "" will be returned.
' Usage:

I actually used pretty much the same code as you above. My service registration in the manifest is the following
<service android:name=".service.MyService" android:enabled="true">
<intent-filter android:label="@string/menuItemStartService" >
<action android:name="it.unibz.bluedroid.bluetooth.service.MY_SERVICE"/>
</intent-filter>
</service>
In the service class I created an according constant string identifying the service name like:
public class MyService extends ForeGroundService {
public static final String MY_SERVICE = "it.unibz.bluedroid.bluetooth.service.MY_SERVICE";
...
}
and from the according Activity I call it with
startService(new Intent(MyService.MY_SERVICE));
and stop it with
stopService(new Intent(MyService.MY_SERVICE));
It works perfectly. Try to check your configuration and if you don't find anything strange try to debug whether your stopService get's called properly.
[[
is bash's improvement to the [
command. It has several enhancements that make it a better choice if you write scripts that target bash. My favorites are:
It is a syntactical feature of the shell, so it has some special behavior that [
doesn't have. You no longer have to quote variables like mad because [[
handles empty strings and strings with whitespace more intuitively. For example, with [
you have to write
if [ -f "$file" ]
to correctly handle empty strings or file names with spaces in them. With [[
the quotes are unnecessary:
if [[ -f $file ]]
Because it is a syntactical feature, it lets you use &&
and ||
operators for boolean tests and <
and >
for string comparisons. [
cannot do this because it is a regular command and &&
, ||
, <
, and >
are not passed to regular commands as command-line arguments.
It has a wonderful =~
operator for doing regular expression matches. With [
you might write
if [ "$answer" = y -o "$answer" = yes ]
With [[
you can write this as
if [[ $answer =~ ^y(es)?$ ]]
It even lets you access the captured groups which it stores in BASH_REMATCH
. For instance, ${BASH_REMATCH[1]}
would be "es" if you typed a full "yes" above.
You get pattern matching aka globbing for free. Maybe you're less strict about how to type yes. Maybe you're okay if the user types y-anything. Got you covered:
if [[ $ANSWER = y* ]]
Keep in mind that it is a bash extension, so if you are writing sh-compatible scripts then you need to stick with [
. Make sure you have the #!/bin/bash
shebang line for your script if you use double brackets.
I've seen
anEvent.isPopupTrigger()
be used before. I'm fairly new to Java so I'm happy to hear thoughts about this approach :)
In the following example you have an PHP array, then firstly create a JavaScript array by a PHP array:
<script type="javascript">
day = new Array(<?php echo implode(',', $day); ?>);
week = new Array(<?php echo implode(',',$week); ?>);
month = new Array(<?php echo implode(',',$month); ?>);
<!-- Then pass it to the JavaScript function: -->
drawChart(<?php echo count($day); ?>, day, week, month);

What sort of button, neither a Forms Control nor an ActiveX control should affect the used range.
It is a known problem that excel does not keep track of the used range very well. Any reference to the used range via VBA will reset the value to the current used range. So try running this sub procedure:
Sub ResetUsedRng()
Application.ActiveSheet.UsedRange
End Sub
Failing that you may well have some formatting hanging round. Try clearing/deleting all the cells after your last row.
Regarding the above also see:
Another method to find the last used cell:
Dim rLastCell As Range
Set rLastCell = ActiveSheet.Cells.Find(What:="*", After:=.Cells(1, 1), LookIn:=xlFormulas, LookAt:= _
xlPart, SearchOrder:=xlByRows, SearchDirection:=xlPrevious, MatchCase:=False)
Change the search direction to find the first used cell.
savefig
specifies the DPI for the saved figure (The default is 100 if it's not specified in your .matplotlibrc, have a look at the dpi
kwarg to savefig
). It doesn't inheret it from the DPI of the original figure.
The DPI affects the relative size of the text and width of the stroke on lines, etc. If you want things to look identical, then pass fig.dpi
to fig.savefig
.
E.g.
import matplotlib.pyplot as plt
fig = plt.figure()
plt.plot(range(10))
fig.savefig('temp.png', dpi=fig.dpi)
Also from guava libraries... com.google.common.primitives.Ints:
List<Integer> Ints.asList(int...)
You need to include the appropriate header
#include <stdio.h>
If you're not sure which header a standard function is defined in, the function's man page will state this.
There are some great answers above, but this is how I did it:
public static int[] test(int[] arr) {
int[] output = arr.clone();
for (int i = arr.length - 1; i > -1; i--) {
output[i] = arr[arr.length - i - 1];
}
return output;
}
You can just reverse your log and just head it for the first result.
git log --pretty=oneline --reverse | head -1
How about writing your own concat method?
public static Stream<T> concat(Stream<? extends T> a,
Stream<? extends T> b,
Stream<? extends T> args)
{
Stream<T> concatenated = Stream.concat(a, b);
for (Stream<T> stream : args)
{
concatenated = Stream.concat(concatenated, stream);
}
return concatenated;
}
This at least makes your first example a lot more readable.
This link explains where you're going wrong:
Place the definition of your constructors, destructors methods and whatnot in your header file, and that will correct the problem.
This offers another solution:
How can I avoid linker errors with my template functions?
However this requires you to anticipate how your template will be used and, as a general solution, is counter-intuitive. It does solve the corner case though where you develop a template to be used by some internal mechanism, and you want to police the manner in which it is used.
JSON syntax is pretty much the JavaScript syntax for coding your object. Therefore, in terms of conciseness and speed, your own answer is the best bet.
I use this approach when populating dropdown lists in my KnockoutJS model. E.g.
var desktopGrpViewModel = {
availableComputeOfferings: ko.observableArray(@Html.Raw(JsonConvert.SerializeObject(ViewBag.ComputeOfferings))),
desktopGrpComputeOfferingSelected: ko.observable(),
};
ko.applyBindings(desktopGrpViewModel);
...
<select name="ComputeOffering" class="form-control valid" id="ComputeOffering" data-val="true"
data-bind="options: availableComputeOffering,
optionsText: 'Name',
optionsValue: 'Id',
value: desktopGrpComputeOfferingSelect,
optionsCaption: 'Choose...'">
</select>
Note that I'm using Json.NET NuGet package for serialization and the ViewBag to pass data.
I think you can almost do exactly what you thought would be ideal, using the statsmodels package which was one of pandas
' optional dependencies before pandas
' version 0.20.0 (it was used for a few things in pandas.stats
.)
>>> import pandas as pd
>>> import statsmodels.formula.api as sm
>>> df = pd.DataFrame({"A": [10,20,30,40,50], "B": [20, 30, 10, 40, 50], "C": [32, 234, 23, 23, 42523]})
>>> result = sm.ols(formula="A ~ B + C", data=df).fit()
>>> print(result.params)
Intercept 14.952480
B 0.401182
C 0.000352
dtype: float64
>>> print(result.summary())

You're getting None
because list.sort()
it operates in-place, meaning that it doesn't return anything, but modifies the list itself. You only need to call a.sort()
without assigning it to a
again.
There is a built in function sorted()
, which returns a sorted version of the list - a = sorted(a)
will do what you want as well.
form.MySelect.options[form.MySelect.selectedIndex].value
Combining the recommendations from others for specifying a character encoding and buffering the input, here's what I think is a pretty complete answer.
Assuming you have a File
object representing the file you want to read:
BufferedReader reader = new BufferedReader(
new InputStreamReader(
new FileInputStream(file),
Charset.forName("UTF-8")));
int c;
while((c = reader.read()) != -1) {
char character = (char) c;
// Do something with your character
}
For people wanting a quick solution to this problem:
<dependency>
<groupId>LIB_NAME</groupId>
<artifactId>LIB_NAME</artifactId>
<version>1.0.0</version>
<scope>system</scope>
<systemPath>${basedir}/WebContent/WEB-INF/lib/YOUR_LIB.jar</systemPath>
</dependency>
just give your library a unique groupID and artifact name and point to where it is in the file system. You are good to go.
Of course this is a dirty quick fix that will ONLY work on your machine and if you don't change the path to the libs. But some times, that's all you want, to run and do a few tests.
EDIT: just re-red the question and realised the user was already using my solution as a temporary fix. I'll leave my answer as a quick help for others that come to this question. If anyone disagrees with this please leave me a comment. :)
For each error of the form:
npm WARN {something} requires a peer of {other thing} but none is installed. You must install peer dependencies yourself.
You should:
$ npm install --save-dev "{other thing}"
Note: The quotes are needed if the {other thing}
has spaces, like in this example:
npm WARN [email protected] requires a peer of rollup@>=0.66.0 <2 but none was installed.
Resolved with:
$ npm install --save-dev "rollup@>=0.66.0 <2"
I needed to read the results returned from a server in JSON where I couldn't guarantee the fields would be present. I'm using class org.json.simple.JSONObject which is derived from HashMap. Here are some helper functions I employed:
public static String getString( final JSONObject response,
final String key )
{ return getString( response, key, "" ); }
public static String getString( final JSONObject response,
final String key, final String defVal )
{ return response.containsKey( key ) ? (String)response.get( key ) : defVal; }
public static long getLong( final JSONObject response,
final String key )
{ return getLong( response, key, 0 ); }
public static long getLong( final JSONObject response,
final String key, final long defVal )
{ return response.containsKey( key ) ? (long)response.get( key ) : defVal; }
public static float getFloat( final JSONObject response,
final String key )
{ return getFloat( response, key, 0.0f ); }
public static float getFloat( final JSONObject response,
final String key, final float defVal )
{ return response.containsKey( key ) ? (float)response.get( key ) : defVal; }
public static List<JSONObject> getList( final JSONObject response,
final String key )
{ return getList( response, key, new ArrayList<JSONObject>() ); }
public static List<JSONObject> getList( final JSONObject response,
final String key, final List<JSONObject> defVal ) {
try { return response.containsKey( key ) ? (List<JSONObject>) response.get( key ) : defVal; }
catch( ClassCastException e ) { return defVal; }
}
I want to return odd numbers of an array
If i read that correctly, you want something like this?
List<Integer> getOddNumbers(int[] integers) {
List<Integer> oddNumbers = new ArrayList<Integer>();
for (int i : integers)
if (i % 2 != 0)
oddNumbers.add(i);
return oddNumbers;
}
If you have only one checkbox, you can do this easily with just ng-model:
<input type="checkbox" ng-model="checked"/>
<button ng-disabled="!checked"> Next </button>
And initialize $scope.checked in your Controller (default=false). The official doc discourages the use of ng-init in that case.

2018 now. You don't need any extensions for auto-imports in Javascript (as long as you have checkjs: true
in your jsconfig.json
file) and TypeScript.
There are two types of auto imports: the add missing import quick fix which shows up as a lightbulb on errors:
And the auto import suggestions. These show up a suggestion items as you type. Accepting an auto import suggestion automatically adds the import at the top of the file
Both should work out of the box with JavaScript and TypeScript. If auto imports still do not work for you, please open an issue
Check again. Use debugger if must. My guess is that for some item in userResponseDetails this query finds no elements:
.Where(y => y.ResponseId.Equals(item.ResponseId))
so you can't call
.First()
on it. Maybe try
.FirstOrDefault()
if it solves the issue.
Do NOT return NULL value! This is purely so that you can see and diagnose where problem is. Handle these cases properly.

JSON in any HTML tag except <script>
tag would be a mere text. Thus it's like you add a story to your HTML page.
However, about formatting, that's another matter. I guess you should change the title of your question.
No, they are pretty different from each other.
Both are different specializations of @Component annotation (in practice, they're two different implementations of the same interface) so both can be discovered by the classpath scanning (if you declare it in your XML configuration)
@Service annotation is used in your service layer and annotates classes that perform service tasks, often you don't use it but in many case you use this annotation to represent a best practice. For example, you could directly call a DAO class to persist an object to your database but this is horrible. It is pretty good to call a service class that calls a DAO. This is a good thing to perform the separation of concerns pattern.
@Controller annotation is an annotation used in Spring MVC framework (the component of Spring Framework used to implement Web Application). The @Controller annotation indicates that a particular class serves the role of a controller. The @Controller annotation acts as a stereotype for the annotated class, indicating its role. The dispatcher scans such annotated classes for mapped methods and detects @RequestMapping annotations.
So looking at the Spring MVC architecture you have a DispatcherServlet class (that you declare in your XML configuration) that represent a front controller that dispatch all the HTTP Request towards the appropriate controller classes (annotated by @Controller). This class perform the business logic (and can call the services) by its method. These classes (or its methods) are typically annotated also with @RequestMapping annotation that specify what HTTP Request is handled by the controller and by its method.
For example:
@Controller
@RequestMapping("/appointments")
public class AppointmentsController {
private final AppointmentBook appointmentBook;
@Autowired
public AppointmentsController(AppointmentBook appointmentBook) {
this.appointmentBook = appointmentBook;
}
@RequestMapping(method = RequestMethod.GET)
public Map<String, Appointment> get() {
return appointmentBook.getAppointmentsForToday();
}
This class is a controller.
This class handles all the HTTP Request toward "/appointments" "folder" and in particular the get method is the method called to handle all the GET HTTP Request toward the folder "/appointments".
I hope that now it is more clear for you.

With this we can pass a key function to use for the sorting
Array.prototype.sortBy = function(key_func, reverse=false){
return this.sort( (a, b) => {
var keyA = key_func(a),
keyB = key_func(b);
if(keyA < keyB) return reverse? 1: -1;
if(keyA > keyB) return reverse? -1: 1;
return 0;
});
}
Then for example if we have
var arr = [ {date: "01/12/00", balls: {red: "a8", blue: 10}},
{date: "12/13/05", balls: {red: "d6" , blue: 11}},
{date: "03/02/04", balls: {red: "c4" , blue: 15}} ]
We can do
arr.sortBy(el => el.balls.red)
/* would result in
[ {date: "01/12/00", balls: {red: "a8", blue: 10}},
{date: "03/02/04", balls: {red: "c4", blue: 15}},
{date: "12/13/05", balls: {red: "d6", blue: 11}} ]
*/
or
arr.sortBy(el => new Date(el.date), true) // second argument to reverse it
/* would result in
[ {date: "12/13/05", balls: {red: "d6", blue:11}},
{date: "03/02/04", balls: {red: "c4", blue:15}},
{date: "01/12/00", balls: {red: "a8", blue:10}} ]
*/
or
arr.sortBy(el => el.balls.blue + parseInt(el.balls.red[1]))
/* would result in
[ {date: "12/13/05", balls: {red: "d6", blue:11}}, // red + blue= 17
{date: "01/12/00", balls: {red: "a8", blue:10}}, // red + blue= 18
{date: "03/02/04", balls: {red: "c4", blue:15}} ] // red + blue= 19

`List<String> unavailable = list1.stream()
.filter(e -> (list2.stream()
.filter(d -> d.getStr().equals(e))
.count())<1)
.collect(Collectors.toList());`
for this if i change to
`List<String> unavailable = list1.stream()
.filter(e -> (list2.stream()
.filter(d -> d.getStr().equals(e))
.count())>0)
.collect(Collectors.toList());`
will it give me list1 matched with list2 right?
WooCommerce has a number of options for modifying the cart, and checkout pages. Here are the three I'd recomend:
is_cart()
and is_checkout()
functions return true on their page. Example:
if ( is_cart() || is_checkout() ) {
echo "This is the cart, or checkout page!";
}
The main, cart template file is located at wp-content/themes/{current-theme}/woocommerce/cart/cart.php
The main, checkout template file is located at wp-content/themes/{current-theme}/woocommerce/checkout/form-checkout.php
To edit these, first copy them to your child theme.
wp-content/themes/{current-theme}/page-{slug}.php
page-{slug}.php
is the second template that will be used, coming after manually assigned ones through the WP dashboard.
This is safer than my other solutions, because if you remove WooCommerce, but forget to remove this file, the code inside (that may rely on WooCommerce functions) won't break, because it's never called (unless of cause you have a page with slug {slug}
).
For example:
wp-content/themes/{current-theme}/page-cart.php
wp-content/themes/{current-theme}/page-checkout.php
mail can represent quite a couple of programs on a linux system. What you want behind it is either sendmail or postfix. I recommend the latter.
You can install it via your favorite package manager. Then you have to configure it, and once you have done that, you can send email like this:
echo "My message" | mail -s subject [email protected]
See the manual for more information.
As far as configuring postfix goes, there's plenty of articles on the internet on how to do it. Unless you're on a public server with a registered domain, you generally want to forward the email to a SMTP server that you can send email from.
For gmail, for example, follow http://rtcamp.com/tutorials/linux/ubuntu-postfix-gmail-smtp/ or any other similar tutorial.
You need to name the entity that holds the association to User. For example,
... INNER JOIN ug.user u ...
That's the "path" the error message is complaining about -- path from UserGroup to User entity.
Hibernate relies on declarative JOINs, for which the join condition is declared in the mapping metadata. This is why it is impossible to construct the native SQL query without having the path.
On CentOS 7, the pip
version is pip3.4
and is located here:

For the following code you have to enable mssql in the php.ini as described at this link: http://www.php.net/manual/en/mssql.installation.php
$myServer = "10.85.80.229";
$myUser = "root";
$myPass = "pass";
$myDB = "testdb";
$conn = mssql_connect($myServer,$myUser,$myPass);
if (!$conn)
{
die('Not connected : ' . mssql_get_last_message());
}
$db_selected = mssql_select_db($myDB, $conn);
if (!$db_selected)
{
die ('Can\'t use db : ' . mssql_get_last_message());
}
I think this way you can get the file from "anywhere" (including server locations) and you do not need to care about where to put it.
It's usually a bad practice having to care about such things.
Thread.currentThread().getContextClassLoader().getResourceAsStream("abc.properties");
From my HomeController I want to call this Method and convert Json response to List
No you don't. You really don't want to add the overhead of an HTTP call and (de)serialization when the code is within reach. It's even in the same assembly!
Your ApiController goes against (my preferred) convention anyway. Let it return a concrete type:
public IEnumerable<QDocumentRecord> GetAllRecords()
{
listOfFiles = ...
return listOfFiles;
}
If you don't want that and you're absolutely sure you need to return HttpResponseMessage
, then still there's absolutely no need to bother with calling JsonConvert.SerializeObject()
yourself:
return Request.CreateResponse<List<QDocumentRecord>>(HttpStatusCode.OK, listOfFiles);
Then again, you don't want business logic in a controller, so you extract that into a class that does the work for you:
public class FileListGetter
{
public IEnumerable<QDocumentRecord> GetAllRecords()
{
listOfFiles = ...
return listOfFiles;
}
}
Either way, then you can call this class or the ApiController directly from your MVC controller:
public class HomeController : Controller
{
public ActionResult Index()
{
var listOfFiles = new DocumentsController().GetAllRecords();
// OR
var listOfFiles = new FileListGetter().GetAllRecords();
return View(listOfFiles);
}
}
But if you really, really must do an HTTP request, you can use HttpWebRequest
, WebClient
, HttpClient
or RestSharp
, for all of which plenty of tutorials exist.
You can cast this value to a Boolean in a very simple manner: by comparing it with integer value 1, like this:
boolean multipleContacts = new Integer(1).equals(jsonObject.get("MultipleContacts"))
If it is a String, you could do this:
boolean multipleContacts = "1".equals(jsonObject.get("MultipleContacts"))
There is no feature in scp to filter files. For "advanced" stuff like this, I recommend using rsync:
rsync -av --exclude '*.svn' user@server:/my/dir .
(this line copy rsync from distant folder to current one)
Recent versions of rsync tunnel over an ssh connection automatically by default.
You can't create arrays with a generic component type.
Create an array of an explicit type, like Object[]
, instead. You can then cast this to PCB[]
if you want, but I don't recommend it in most cases.
PCB[] res = (PCB[]) new Object[list.size()]; /* Not type-safe. */
If you want type safety, use a collection like java.util.List<PCB>
instead of an array.
By the way, if list
is already a java.util.List
, you should use one of its toArray()
methods, instead of duplicating them in your code. This doesn't get your around the type-safety problem though.
The above are all excellent answers. I just wanted to add that when there are multiple characters to check against, an if-else might turn out better since you could instead write the following.
// switch on vowels, digits, punctuation, or consonants
char c; // assign some character to 'c'
if ("aeiouAEIOU".indexOf(c) != -1) {
// handle vowel case
} else if ("!@#$%,.".indexOf(c) != -1) {
// handle punctuation case
} else if ("0123456789".indexOf(c) != -1) {
// handle digit case
} else {
// handle consonant case, assuming other characters are not possible
}
Of course, if this gets any more complicated, I'd recommend a regex matcher.
You just need to specify a minimum date - setting it to 0 means that the minimum date is 0 days from today i.e. today. You could pass the string '0d'
instead (the default unit is days).
$(function () {
$('#date').datepicker({ minDate: 0 });
});
This worked for me.

If you want that image to be zoomed on mouse hover :
$(document).ready( function() {
$('#div img').hover(
function() {
$(this).animate({ 'zoom': 1.2 }, 400);
},
function() {
$(this).animate({ 'zoom': 1 }, 400);
});
});
?or you may do like this if zoom in and out buttons are used :
$("#ZoomIn").click(ZoomIn());
$("#ZoomOut").click(ZoomOut());

You really shouldn't be doing this, the correct use of timeout is the right tool for the OP's problem and any other occasion where you just want to run something after a period of time. Joseph Silber has demonstrated that well in his answer. However, if in some non-production case you really want to hang the main thread for a period of time, this will do it.
function wait(ms){
var start = new Date().getTime();
var end = start;
while(end < start + ms) {
end = new Date().getTime();
}
}
With execution in the form:
console.log('before');
wait(7000); //7 seconds in milliseconds
console.log('after');
I've arrived here because I was building a simple test case for sequencing a mix of asynchronous operations around long-running blocking operations (i.e. expensive DOM manipulation) and this is my simulated blocking operation. It suits that job fine, so I thought I post it for anyone else who arrives here with a similar use case. Even so, it's creating a Date() object in a while loop, which might very overwhelm the GC if it runs long enough. But I can't emphasize enough, this is only suitable for testing, for building any actual functionality you should refer to Joseph Silber's answer.
It works with just this:
.slideContainer {
white-space: nowrap;
}
.slide {
display: inline-block;
width: 600px;
white-space: normal;
}
I did originally have float : left;
and that prevented it from working correctly.
Thanks for posting this solution.
selecting
with the the help of the mouse
and right-click copy
worked in my case.
I didn't want the line numbers included so I :set nonumber
before copying
.
Sounds like a job for set
with a custom IFS
.
IFS=-
set $STR
var1=$1
var2=$2
(You will want to do this in a function with a local IFS
so you don't mess up other parts of your script where you require IFS
to be what you expect.)

Just a helpful hint, there is a company called Yodlee.com who provides this data. They do charge for the API. Companies like Mint.com use this API to gather bank and financial account data.
Also, checkout https://plaid.com/, they are a similar company Yodlee.com and provide both authentication API for several banks and REST-based transaction fetching endpoints.

i tend to use this calculation a lot in things i make, so i like to add it to the Math object:
Math.dist=function(x1,y1,x2,y2){
if(!x2) x2=0;
if(!y2) y2=0;
return Math.sqrt((x2-x1)*(x2-x1)+(y2-y1)*(y2-y1));
}
Math.dist(0,0, 3,4); //the output will be 5
Math.dist(1,1, 4,5); //the output will be 5
Math.dist(3,4); //the output will be 5
Update:
this approach is especially happy making when you end up in situations something akin to this (i often do):
varName.dist=Math.sqrt( ( (varName.paramX-varX)/2-cx )*( (varName.paramX-varX)/2-cx ) + ( (varName.paramY-varY)/2-cy )*( (varName.paramY-varY)/2-cy ) );
that horrid thing becomes the much more manageable:
varName.dist=Math.dist((varName.paramX-varX)/2, (varName.paramY-varY)/2, cx, cy);
The idiom is to use the bitwise or-equal operator to set bits:
flags |= 0x04;
To clear a bit, the idiom is to use bitwise and with negation:
flags &= ~0x04;
Sometimes you have an offset that identifies your bit, and then the idiom is to use these combined with left-shift:
flags |= 1 << offset;
flags &= ~(1 << offset);
In MySQL you could try:
SELECT * FROM A INNER JOIN B ON B.MYCOL LIKE CONCAT('%', A.MYCOL, '%');
Of course this would be a massively inefficient query because it would do a full table scan.
Update: Here's a proof
create table A (MYCOL varchar(255));
create table B (MYCOL varchar(255));
insert into A (MYCOL) values ('foo'), ('bar'), ('baz');
insert into B (MYCOL) values ('fooblah'), ('somethingfooblah'), ('foo');
insert into B (MYCOL) values ('barblah'), ('somethingbarblah'), ('bar');
SELECT * FROM A INNER JOIN B ON B.MYCOL LIKE CONCAT('%', A.MYCOL, '%');
+-------+------------------+
| MYCOL | MYCOL |
+-------+------------------+
| foo | fooblah |
| foo | somethingfooblah |
| foo | foo |
| bar | barblah |
| bar | somethingbarblah |
| bar | bar |

LoadLibrary
does not do what you think it does. It loads the DLL into the memory of the current process, but it does not magically import functions defined in it! This wouldn't be possible, as function calls are resolved by the linker at compile time while LoadLibrary
is called at runtime (remember that C++ is a statically typed language).
You need a separate WinAPI function to get the address of dynamically loaded functions: GetProcAddress
.
Example
#include <windows.h>
#include <iostream>
/* Define a function pointer for our imported
* function.
* This reads as "introduce the new type f_funci as the type:
* pointer to a function returning an int and
* taking no arguments.
*
* Make sure to use matching calling convention (__cdecl, __stdcall, ...)
* with the exported function. __stdcall is the convention used by the WinAPI
*/
typedef int (__stdcall *f_funci)();
int main()
{
HINSTANCE hGetProcIDDLL = LoadLibrary("C:\\Documents and Settings\\User\\Desktop\\test.dll");
if (!hGetProcIDDLL) {
std::cout << "could not load the dynamic library" << std::endl;
return EXIT_FAILURE;
}
// resolve function address here
f_funci funci = (f_funci)GetProcAddress(hGetProcIDDLL, "funci");
if (!funci) {
std::cout << "could not locate the function" << std::endl;
return EXIT_FAILURE;
}
std::cout << "funci() returned " << funci() << std::endl;
return EXIT_SUCCESS;
}
Also, you should export your function from the DLL correctly. This can be done like this:
int __declspec(dllexport) __stdcall funci() {
// ...
}
As Lundin notes, it's good practice to free the handle to the library if you don't need them it longer. This will cause it to get unloaded if no other process still holds a handle to the same DLL.
Actually this would go faster in most of cases:
SELECT *
FROM table ta1
JOIN table ta2 on ta1.id != ta2.id
WHERE ta1.c2 = ta2.c2 and ta1.c3 = ta2.c3 and ta1.c4 = ta2.c4
You join on different rows which have the same values. I think it should work. Correct me if I'm wrong.

I wonder that nobody has mentioned this, But the easiest way of getting the last used cell is:
Function GetLastCell(sh as Worksheet) As Range
GetLastCell = sh.Cells(1,1).SpecialCells(xlLastCell)
End Function
This essentially returns the same cell that you get by Ctrl + End after selecting Cell A1
.
A word of caution: Excel keeps track of the most bottom-right cell that was ever used in a worksheet. So if for example you enter something in B3 and something else in H8 and then later on delete the contents of H8, pressing Ctrl + End will still take you to H8 cell. The above function will have the same behavior.

Here's how you can test the process:

LocalDate.of( 1985 , 1 , 1 )
…or…
LocalDate.of( 1985 , Month.JANUARY , 1 )
The java.util.Date
, java.util.Calendar
, and java.text.SimpleDateFormat
classes were rushed too quickly when Java first launched and evolved. The classes were not well designed or implemented. Improvements were attempted, thus the deprecations you’ve found. Unfortunately the attempts at improvement largely failed. You should avoid these classes altogether. They are supplanted in Java 8 by new classes.
A java.util.Date has both a date and a time portion. You ignored the time portion in your code. So the Date class will take the beginning of the day as defined by your JVM’s default time zone and apply that time to the Date object. So the results of your code will vary depending on which machine it runs or which time zone is set. Probably not what you want.
If you want just the date, without the time portion, such as for a birth date, you may not want to use a Date
object. You may want to store just a string of the date, in ISO 8601 format of YYYY-MM-DD
. Or use a LocalDate
object from Joda-Time (see below).
First thing to learn in Java: Avoid the notoriously troublesome java.util.Date & java.util.Calendar classes bundled with Java.
As correctly noted in the answer by user3277382, use either Joda-Time or the new java.time.* package in Java 8.
DateTimeZone timeZoneNorway = DateTimeZone.forID( "Europe/Oslo" );
DateTime birthDateTime_InNorway = new DateTime( 1985, 1, 1, 3, 2, 1, timeZoneNorway );
DateTimeZone timeZoneNewYork = DateTimeZone.forID( "America/New_York" );
DateTime birthDateTime_InNewYork = birthDateTime_InNorway.toDateTime( timeZoneNewYork );
DateTime birthDateTime_UtcGmt = birthDateTime_InNorway.toDateTime( DateTimeZone.UTC );
LocalDate birthDate = new LocalDate( 1985, 1, 1 );
Dump to console…
System.out.println( "birthDateTime_InNorway: " + birthDateTime_InNorway );
System.out.println( "birthDateTime_InNewYork: " + birthDateTime_InNewYork );
System.out.println( "birthDateTime_UtcGmt: " + birthDateTime_UtcGmt );
System.out.println( "birthDate: " + birthDate );
When run…
birthDateTime_InNorway: 1985-01-01T03:02:01.000+01:00
birthDateTime_InNewYork: 1984-12-31T21:02:01.000-05:00
birthDateTime_UtcGmt: 1985-01-01T02:02:01.000Z
birthDate: 1985-01-01
In this case the code for java.time is nearly identical to that of Joda-Time.
We get a time zone (ZoneId
), and construct a date-time object assigned to that time zone (ZonedDateTime
). Then using the Immutable Objects pattern, we create new date-times based on the old object’s same instant (count of nanoseconds since epoch) but assigned other time zone. Lastly we get a LocalDate
which has no time-of-day nor time zone though notice the time zone applies when determining that date (a new day dawns earlier in Oslo than in New York for example).
ZoneId zoneId_Norway = ZoneId.of( "Europe/Oslo" );
ZonedDateTime zdt_Norway = ZonedDateTime.of( 1985 , 1 , 1 , 3 , 2 , 1 , 0 , zoneId_Norway );
ZoneId zoneId_NewYork = ZonedId.of( "America/New_York" );
ZonedDateTime zdt_NewYork = zdt_Norway.withZoneSameInstant( zoneId_NewYork );
ZonedDateTime zdt_Utc = zdt_Norway.withZoneSameInstant( ZoneOffset.UTC ); // Or, next line is similar.
Instant instant = zdt_Norway.toInstant(); // Instant is always in UTC.
LocalDate localDate_Norway = zdt_Norway.toLocalDate();
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date
, Calendar
, & SimpleDateFormat
.
The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.
You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.*
classes.
Where to obtain the java.time classes?
The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval
, YearWeek
, YearQuarter
, and more.
If You are using windows version it is quite easy.

Relative paths are fine and quotes aren't necessary. Another thing that can help is to use the "shorthand" background
property to specify a background color in case the image doesn't load or isn't available for some reason.
#elementID {
background: #000 url(images/slides/background.jpg) repeat-x top left;
}
Notice also that you can specify whether the image will repeat and in what direction (if you don't specify, the default is to repeat horizontally and vertically), and also the location of the image relative to its container.
Just break out where you need to.

Every SQL batch has to fit in the Batch Size Limit: 65,536 * Network Packet Size.
Other than that, your query is limited by runtime conditions. It will usually run out of stack size because x IN (a,b,c) is nothing but x=a OR x=b OR x=c which creates an expression tree similar to x=a OR (x=b OR (x=c)), so it gets very deep with a large number of OR. SQL 7 would hit a SO at about 10k values in the IN, but nowdays stacks are much deeper (because of x64), so it can go pretty deep.
Update
You already found Erland's article on the topic of passing lists/arrays to SQL Server. With SQL 2008 you also have Table Valued Parameters which allow you to pass an entire DataTable as a single table type parameter and join on it.
XML and XPath is another viable solution:
SELECT ...
FROM Table
JOIN (
SELECT x.value(N'.',N'uniqueidentifier') as guid
FROM @values.nodes(N'/guids/guid') t(x)) as guids
ON Table.guid = guids.guid;
I Use this query:
select floor(RAND() * (SELECT MAX(key) FROM table)) from table limit 10
query time:0.016s
If double backslash looks weird to you, C# also allows verbatim string literals where the escaping is not required.
Console.WriteLine(@"Mango \ Nightangle");
Don't you just wish Java had something like this ;-)
We can use drush command also to check logs
drush watchdog-show
it will show recent 10 messages.
or if we want to continue showing logs with more information we can user
drush watchdog-show --tail --full.
Using query-js you can do it like this
list.keys().select(function(k){
return {
key: k,
value : list[k]
}
}).orderBy(function(e){ return e.value;});
You can find an introductory article on query-js here

var sendbtn = document.getElementById('sendNewSms');
checker.onchange = function() {
sendbtn.disabled = !!this.checked;

It will be hard to work in C# without knowing how to work with strings and booleans. But anyway:
String str = "ABC";

Logical Processing Order of the SELECT statement
The following steps show the logical processing order, or binding order, for a SELECT statement. This order determines when the objects defined in one step are made available to the clauses in subsequent steps. For example, if the query processor can bind to (access) the tables or views defined in the FROM clause, these objects and their columns are made available to all subsequent steps. Conversely, because the SELECT clause is step 8, any column aliases or derived columns defined in that clause cannot be referenced by preceding clauses. However, they can be referenced by subsequent clauses such as the ORDER BY clause. Note that the actual physical execution of the statement is determined by the query processor and the order may vary from this list.
- FROM
- ON
- JOIN
- WHERE
- GROUP BY
- WITH CUBE or WITH ROLLUP
- HAVING
- SELECT
- DISTINCT
- ORDER BY
- TOP

No, you can not have a generic "eval" in Java (or any compiled language). Unless you're willing to write a Java compiler AND a JVM to be executed inside of your Java program.
Yes, you can have some library to evaluate numeric algebraic expressions like the one above - see this thread for discussion.

I ran into this on my Mac using the MacPorts vim with +python. Problem was that the MacPorts vim will only bind to python 2.5 with +python, while my extensions were installed under python 2.7. Installing the extensions using pip-2.5 solved it.
I had the same error:
"Syntax error, unrecognized expression: // "
It is known bug at JQuery, so i needed to think on workaround solution,
What I did is:
I changed "script" tag to "div"
and added at angular this code
and the error is gone...
app.run(['$templateCache', function($templateCache) {
var url = "survey-input.html";
content = angular.element(document.getElementById(url)).html()
$templateCache.put(url, content);
}]);
An alternative to Apache Commons: Use Spring's HtmlUtils.htmlEscape(String input)
method.
If you want every cell in the grid to have the same background color, you can just do this:
dataGridView1.DefaultCellStyle.BackColor = Color.Green;
Should be
private ArrayList<String[]> action = new ArrayList<String[]>();
action.add(new String[2]);
...
You can't specify the size of the array within the generic parameter, only add arrays of specific size to the list later. This also means that the compiler can't guarantee that all sub-arrays be of the same size, it must be ensured by you.
A better solution might be to encapsulate this within a class, where you can ensure the uniform size of the arrays as a type invariant.
You can setup your own shortcut in the UI (for the latest master version):
This menu can be found in Help > Keyboard Shortcuts
in any open notebook.
For me it was not a good practice to check the connection state in the Activity class, because
ConnectivityManager cm =
(ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
should be called there, or you need to push down your Activity instance (context) to the connection handler class to able to check the connection state there When no available connection (wifi, network) I catch the UnknownHostException exception:
JSONObject jObj = null;
Boolean responded = false;
HttpGet requestForTest = new HttpGet("http://myserver.com");
try {
new DefaultHttpClient().execute(requestForTest);
responded = true;
} catch (UnknownHostException e) {
jObj = new JSONObject();
try {
jObj.put("answer_code", 1);
jObj.put("answer_text", "No available connection");
} catch (Exception e1) {}
return jObj;
} catch (IOException e) {
e.printStackTrace();
}
In this way I can handle this case along with the other cases in the same class (my server always response back with a json string)
As I explain in my answer to another question, PECS is a mnemonic device created by Josh Bloch to help remember Producer extends
, Consumer super
.
This means that when a parameterized type being passed to a method will produce instances of
T
(they will be retrieved from it in some way),? extends T
should be used, since any instance of a subclass ofT
is also aT
.When a parameterized type being passed to a method will consume instances of
T
(they will be passed to it to do something),? super T
should be used because an instance ofT
can legally be passed to any method that accepts some supertype ofT
. AComparator<Number>
could be used on aCollection<Integer>
, for example.? extends T
would not work, because aComparator<Integer>
could not operate on aCollection<Number>
.
Note that generally you should only be using ? extends T
and ? super T
for the parameters of some method. Methods should just use T
as the type parameter on a generic return type.
Do just simple thing:
It could be quotes themselves that are the entire problem. I had a similar problem and it was due to quotes around the column name in the CREATE TABLE statement. Note there were no whitespace issues, just quotes causing problems.
The column looked like it was called anID
but was really called "anID"
. The quotes don't appear in typical queries so it was hard to detect (for this postgres rookie). This is on postgres 9.4.1
Some more detail:
Doing postgres=# SELECT * FROM test;
gave:
anID | value
------+-------
1 | hello
2 | baz
3 | foo (3 rows)
but trying to select just the first column SELECT anID FROM test;
resulted in an error:
ERROR: column "anid" does not exist
LINE 1: SELECT anID FROM test;
^
Just looking at the column names didn't help:
postgres=# \d test;
Table "public.test"
Column | Type | Modifiers
--------+-------------------+-----------
anID | integer | not null
value | character varying |
Indexes:
"PK on ID" PRIMARY KEY, btree ("anID")
but in pgAdmin if you click on the column name and look in the SQL pane it populated with:
ALTER TABLE test ADD COLUMN "anID" integer;
ALTER TABLE test ALTER COLUMN "anID" SET NOT NULL;
and lo and behold there are the quoutes around the column name. So then ultimately postgres=# select "anID" FROM test;
works fine:
anID
------
1
2
3
(3 rows)
Same moral, don't use quotes.
Um...question: Does it need to have at least one character or no? Can it be an empty string?
^[A-Za-z0-9_]+$
Will do at least one upper or lower case alphanumeric or underscore. If it can be zero length, then just substitute the + for *
^[A-Za-z0-9_]*$
Edit:
If diacritics need to be included (such as cedilla - ç) then you would need to use the word character which does the same as the above, but includes the diacritic characters:
^\w+$
Or
^\w*$

Honestly though, whether there is a way for it to evaluate to true or not (and as others have shown, there are multiple ways), the answer I'd be looking for, speaking as someone who has conducted hundreds of interviews, would be something along the lines of:
"Well, maybe yes under some weird set of circumstances that aren't immediately obvious to me... but if I encountered this in real code then I would use common debugging techniques to figure out how and why it was doing what it was doing and then immediately refactor the code to avoid that situation... but more importantly: I would absolutely NEVER write that code in the first place because that is the very definition of convoluted code, and I strive to never write convoluted code".
I guess some interviewers would take offense to having what is obviously meant to be a very tricky question called out, but I don't mind developers who have an opinion, especially when they can back it up with reasoned thought and can dovetail my question into a meaningful statement about themselves.

__getitem__
minimal ...
example in a custom class
When the magic syntax ...
gets passed to []
in a custom class, __getitem__()
receives a Ellipsis
class object.
The class can then do whatever it wants with this Singleton object.
Example:
class C(object):
def __getitem__(self, k):
return k
# Single argument is passed directly.
assert C()[0] == 0
# Multiple indices generate a tuple.
assert C()[0, 1] == (0, 1)
# Slice notation generates a slice object.
assert C()[1:2:3] == slice(1, 2, 3)
# Ellipsis notation generates the Ellipsis class object.
# Ellipsis is a singleton, so we can compare with `is`.
assert C()[...] is Ellipsis
# Everything mixed up.
assert C()[1, 2:3:4, ..., 6] == (1, slice(2,3,4), Ellipsis, 6)
The Python built-in list
class chooses to give it the semantic of a range, and any sane usage of it should too of course.
Personally, I'd just stay away from it in my APIs, and create a separate, more explicit method instead.
Tested in Python 3.5.2 and 2.7.12.

It comes down to whether the feature is used by one person or if others are working off of it.
You can force the push after the rebase if it's just you:
git push origin feature -f
However, if others are working on it, you should merge and not rebase off of master.
git merge master
git push origin feature
This will ensure that you have a common history with the people you are collaborating with.
On a different level, you should not be doing back-merges. What you are doing is polluting your feature branch's history with other commits that don't belong to the feature, making subsequent work with that branch more difficult - rebasing or not.
This is my article on the subject called branch per feature.
Hope this helps.
