My situation was a little different. The solution was to strip the .pem from everything outside of the CERTIFICATE and PRIVATE KEY sections and to invert the order which they appeared. After converting from pfx to pem file, the certificate looked like this:
Bag Attributes
localKeyID: ...
issuer=...
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----
Bag Attributes
more garbage...
-----BEGIN PRIVATE KEY-----
...
-----END PRIVATE KEY-----
After correcting the file, it was just:
-----BEGIN PRIVATE KEY-----
...
-----END PRIVATE KEY-----
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----
There is a fairly simple answer with powershell.
Import-PfxCertificate -Password $secure_pw -CertStoreLocation Cert:\LocalMachine\Root -FilePath certs.pfx
The trick is making a "secure" password...
$plaintext_pw = 'PASSWORD';
$secure_pw = ConvertTo-SecureString $plaintext_pw -AsPlainText -Force;
Import-PfxCertificate -Password $secure_pw -CertStoreLocation Cert:\LocalMachine\Root -FilePath certs.pfx;
Use an SqlDataAdapter when wanting to populate an in-memory DataSet/DataTable from the database. You then have the flexibility to close/dispose off the connection, pass the datatable/set around in memory. You could then manipulate the data and persist it back into the DB using the data adapter, in conjunction with InsertCommand/UpdateCommand.
Use an SqlDataReader when wanting fast, low-memory footprint data access without the need for flexibility for e.g. passing the data around your business logic. This is more optimal for quick, low-memory usage retrieval of large data volumes as it doesn't load all the data into memory all in one go - with the SqlDataAdapter approach, the DataSet/DataTable would be filled with all the data so if there's a lot of rows & columns, that will require a lot of memory to hold.
NSLocale* currentLocale = [NSLocale currentLocale];
[[NSDate date] descriptionWithLocale:currentLocale];
or use
NSDateFormatter *dateFormatter=[[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
// or @"yyyy-MM-dd hh:mm:ss a" if you prefer the time with AM/PM
NSLog(@"%@",[dateFormatter stringFromDate:[NSDate date]]);
You should use the following code :
Class2 cls2 = new Class2();
cls2.UpdateEmployee();
In case you don't want to create a new instance to call the method, you can decalre the method as static
and then you can just call Class2.UpdateEmployee()
.
Same origin policy has nothing to do with sending request to another url (different protocol or domain or port).
It is all about restricting access to (reading) response data from another url. So JavaScript code within a page can post to arbitrary domain or submit forms within that page to anywhere (unless the form is in an iframe with different url).
But what makes these POST requests inefficient is that these requests lack antiforgery tokens, so are ignored by the other url. Moreover, if the JavaScript tries to get that security tokens, by sending AJAX request to the victim url, it is prevented to access that data by Same Origin Policy.

How about using the mysql client like this:
mysql -h <hostname> -u username -p <databasename> < file.sql
You need to add query.addEntity(SwitcherServiceSource.class) before calling the .list() on query.
From MSDN:
A
String
object is a sequential collection ofSystem.Char
objects that represent a string.
So you can use this:
var howManyBytes = yourString.Length * sizeof(Char);
To understand why it is necessary to distinguish between int
and long
literals, consider:
long l = -1 >>> 1;
versus
int a = -1;
long l = a >>> 1;
Now as you would rightly expect, both code fragments give the same value to variable l
. Without being able to distinguish int
and long
literals, what is the interpretation of -1 >>> 1
?
-1L >>> 1 // ?
or
(int)-1 >>> 1 // ?
So even if the number is in the common range, we need to specify type. If the default changed with magnitude of the literal, then there would be a weird change in the interpretations of expressions just from changing the digits.
This does not occur for byte
, short
and char
because they are always promoted before performing arithmetic and bitwise operations. Arguably their should be integer type suffixes for use in, say, array initialisation expressions, but there isn't. float
uses suffix f
and double
d
. Other literals have unambiguous types, with there being a special type for null
.
Single quotes delimit a string constant or a date/time constant.
Double quotes delimit identifiers for e.g. table names or column names. This is generally only necessary when your identifier doesn't fit the rules for simple identifiers.

I suggest you create your own list of operator words that you take out of the stopword list. Sets can be conveniently subtracted, so:
operators = set(('and', 'or', 'not'))
stop = set(stopwords...) - operators
Then you can simply test if a word is in
or not in
the set without relying on whether your operators are part of the stopword list. You can then later switch to another stopword list or add an operator.
if word.lower() not in stop:
# use word

Facebook has changed how the sharer.php works, as Ibrahim Faour replies to the bug filed with Facebook.
The sharer will no longer accept custom parameters and facebook will pull the information that is being displayed in the preview the same way that it would appear on facebook as a post, from the url OG meta tags.
Try this (via Javascript in this example):
'http://www.facebook.com/sharer.php?s=100&p[title]='+encodeURIComponent('this is a title') + '&p[summary]=' + encodeURIComponent('description here') + '&p[url]=' + encodeURIComponent('http://www.nufc.com') + '&p[images][0]=' + encodeURIComponent('http://www.somedomain.com/image.jpg')
I tried this quickly without the image part and the sharer.php window appears pre-populated, so it looks like a solution.
I found this via this SO article:
Want custom title / image / description in facebook share link from a flash app
and this link contained in an answer from Lelis718:

If you have something that's O(f(n)) that means there's are k, g(n) such that f(n) ≤ k g(n).
If you have something that's Ω(f(n)) that means there's are k, g(n) such that f(n) ≥ k g(n).
And if you have a something with O(f(n)) and Ω(f(n)), then it's Θ(f(n).

The aliases you give are for the output of the query - they are not available within the query itself.
You can either repeat the expression:
SELECT neededfield, CONCAT(firstname, ' ', lastname) as firstlast
FROM users
WHERE CONCAT(firstname, ' ', lastname) = "Bob Michael Jones"
or wrap the query
SELECT * FROM (
SELECT neededfield, CONCAT(firstname, ' ', lastname) as firstlast
FROM users) base
WHERE firstLast = "Bob Michael Jones"
If you are programming in PHP, it is useful to split lines by \n
and then trim()

foreach($line in explode("\n", $data))

$line = trim($line);

}

It always a good practice to pass radix with parseInt -
parseInt(string, radix)
For decimal -
parseInt(id.substring(id.length - 1), 10)
If the radix parameter is omitted, JavaScript assumes the following:
A simple way of "binarize" an image is to compare to a threshold: For example you can compare all elements in a matrix against a value with opencv in c++
cv::Mat img = cv::imread("image.jpg", CV_LOAD_IMAGE_GRAYSCALE);
cv::Mat bw = img > 128;
In this way, all pixels in the matrix greater than 128 now are white, and these less than 128 or equals will be black
Optionally, and for me gave good results is to apply blur
cv::blur( bw, bw, cv::Size(3,3) );
Later you can save it as said before with:
cv::imwrite("image_bw.jpg", bw);
element = random.choice(myList)
if element:
# element contains text
else:
# element is empty ''

One can access each element of an array separately using the following code:
Object o=...;
if ( o.getClass().isArray() ) {
for(int i=0; i<Array.getLength(o); i++){
System.out.println(Array.get(o, i));
}
}
Notice that it is unnecessary to know what kind of underlying array it is, as this will work for any array.
Here is the way I use to find the external card. Use mount cmd return then parse the vfat part.
String s = "";
try {
Process process = new ProcessBuilder().command("mount")
.redirectErrorStream(true).start();
process.waitFor();
InputStream is = process.getInputStream();
byte[] buffer = new byte[1024];
while (is.read(buffer) != -1) {
s = s + new String(buffer);
}
is.close();
} catch (Exception e) {
e.printStackTrace();
}
//????mount??
String[] lines = s.split("\n");
for(int i=0; i<lines.length; i++) {
//???????????vfat??,???????????sd????
if(-1 != lines[i].indexOf(path[0]) && -1 != lines[i].indexOf("vfat")) {
//??????
String[] blocks = lines[i].split("\\s");
for(int j=0; j<blocks.length; j++) {
//????????vfat??
if(-1 != blocks[j].indexOf(path[0])) {
//Test if it is the external sd card.
}
}
}
}
@wdavo is correct. The same is also true for functions.
If you override a base function, like Update, then in your subclass you need:
new void Update()
{
//do stufff
}
Without the new at the start of the function decleration you will get the warning flag.
Your code (which looks ok) doesn't return a pointer to an array. It returns a pointer to the first element of an array.
In fact that's usually what you want to do. Most manipulation of arrays are done via pointers to individual elements, not via pointers to the array as a whole.
You can define a pointer to an array, for example this:
double (*p)[42];
defines p
as a pointer to a 42-element array of double
s. A big problem with that is that you have to specify the number of elements in the array as part of the type -- and that number has to be a compile-time constant. Most programs that deal with arrays need to deal with arrays of varying sizes; a given array's size won't vary after it's been created, but its initial size isn't necessarily known at compile time, and different array objects can have different sizes.
A pointer to the first element of an array lets you use either pointer arithmetic or the indexing operator []
to traverse the elements of the array. But the pointer doesn't tell you how many elements the array has; you generally have to keep track of that yourself.
If a function needs to create an array and return a pointer to its first element, you have to manage the storage for that array yourself, in one of several ways. You can have the caller pass in a pointer to (the first element of) an array object, probably along with another argument specifying its size -- which means the caller has to know how big the array needs to be. Or the function can return a pointer to (the first element of) a static array defined inside the function -- which means the size of the array is fixed, and the same array will be clobbered by a second call to the function. Or the function can allocate the array on the heap -- which makes the caller responsible for deallocating it later.
Everything I've written so far is common to C and C++, and in fact it's much more in the style of C than C++. Section 6 of the comp.lang.c FAQ discusses the behavior of arrays and pointers in C.
But if you're writing in C++, you're probably better off using C++ idioms. For example, the C++ standard library provides a number of headers defining container classes such as <vector>
and <array>
, which will take care of most of this stuff for you. Unless you have a particular reason to use raw arrays and pointers, you're probably better off just using C++ containers instead.
EDIT : I think you edited your question as I was typing this answer. The new code at the end of your question is, as you observer, no good; it returns a pointer to an object that ceases to exist as soon as the function returns. I think I've covered the alternatives.

Apparently the free NetDrive software from Novell can access SFTP file servers.
The most direct way is sum(numbers == x)
.
numbers == x
creates a logical vector which is TRUE at every location that x occurs, and when sum
ing, the logical vector is coerced to numeric which converts TRUE to 1 and FALSE to 0.
However, note that for floating point numbers it's better to use something like: sum(abs(numbers - x) < 1e-6)
.
var string = "Hello";
var str = string.substring(0, string.length-1);
alert(str);
foreach (var f in Directory.GetFiles(".", "*.dll"))
Assembly.LoadFrom(f);
That loads all the DLLs present in your executable's folder.
In my case I was trying to use Reflection
to find all subclasses of a class, even in other DLLs. This worked, but I'm not sure if it's the best way to do it.
EDIT: I timed it, and it only seems to load them the first time.
Stopwatch stopwatch = new Stopwatch();
for (int i = 0; i < 4; i++)
{
stopwatch.Restart();
foreach (var f in Directory.GetFiles(".", "*.dll"))
Assembly.LoadFrom(f);
stopwatch.Stop();
Console.WriteLine(stopwatch.ElapsedMilliseconds);
}
Output: 34 0 0 0
So one could potentially run that code before any Reflection searches just in case.
Your tables should have as immediate children just tbody
and thead
elements, with the rows within*. So, amend the HTML to be:
<table border="1" width="100%" id="test">
<tbody>
<tr>
<td>
<table border="1" width="100%">
<tbody>
<tr>
<td>table 2</td>
</tr>
</tbody>
</table>
</td>
</tr>
<tr><td>table 1</td></tr>
<tr><td>table 1</td></tr>
<tr><td>table 1</td></tr>
</tbody>
</table>
Then amend your selector slightly to this:
#test > tbody > tr:last-child { background:#ff0000; }
See it in action here. That makes use of the child selector, which:
...separates two selectors and matches only those elements matched by the second selector that are direct children of elements matched by the first.
So, you are targeting only direct children of tbody
elements that are themselves direct children of your #test
table.
The above is the neatest solution, as you don't need to over-ride any styles. The alternative would be to stick with your current set-up, and over-ride the background style for the inner table, like this:
#test tr:last-child { background:#ff0000; }
#test table tr:last-child { background:transparent; }
* It's not mandatory but most (all?) browsers will add these in, so it's best to make it explicit. As @BoltClock states in the comments:
...it's now set in stone in HTML5, so for a browser to be compliant it basically must behave this way.
It is mainly due to unregistered activity in manifest file as "NextActivity" Firstly register NextActivity in Manifest like

where you have to call the NextActivity..
We can use the following simple code to find repeating and missing values:
int size = 8;
int arr[] = {1, 2, 3, 5, 1, 3};
int result[] = new int[size];
for(int i =0; i < arr.length; i++)
{
if(result[arr[i]-1] == 1)
{
System.out.println("repeating: " + (arr[i]));
}
result[arr[i]-1]++;
}
for(int i =0; i < result.length; i++)
{
if(result[i] == 0)
{
System.out.println("missing: " + (i+1));
}
}
Why don't you use plain html?
<form action="login.php" method="post" name="form1" id="form1">
...
</form>
In your login.php you can then use the header() function.
header("Location: welcome.php");
That approach will be good if the date-time in question is in UTC, or represents local time in an area that has never observed daylight saving time. The DateTime difference routines do not take into account Daylight Saving Time, and consequently will regard midnight June 1 as being a multiple of 24 hours after midnight January 1. I'm unaware of anything in Windows that reports historical daylight-saving rules for the current locale, so I don't think there's any good way to correctly handle any time prior to the most recent daylight-saving rule change.
First, post a message in a chat where your bot is included (channel, group mentioning the bot, or one-to-one chat). Then, just run:
curl https://api.telegram.org/bot<TOKEN>/getUpdates | jq
Feel free to remove the | jq
part if your dont have jq installed, it's only useful for pretty printing. You should get something like this:
You can see the chat ID in the returned json object, together with the chat name and associated message.
Adding strings concatenates them:
> "1" + "1"
"11"
You have to parse them into numbers first:
/* parseFloat is used here.
* Because of it's not known that
* whether the number has fractional places.
*/
var a = parseFloat($('#a').val()),
b = parseFloat($('#b').val());
Also, you have to get the values from inside of the click handler:
$("submit").on("click", function() {
var a = parseInt($('#a').val(), 10),
b = parseInt($('#b').val(), 10);
});
Otherwise, you're using the values of the textboxes from when the page loads.
In case if you are using WPF application using PRISM framework then configuration should exist in your start up project (i.e. in the project where your bootstrapper resides.)
In short just remove it from the class library and put into a start up project.

-webkit-transition: opacity .2s ease-out;
-o-transition: opacity .2s ease-out;

Try like below... it will help you...
Some time in Window Form Focus()
doesn't work correctly. So better you can use Select()
to focus the textbox.
txtbox.Select(); // to Set Focus
txtbox.Select(txtbox.Text.Length, 0); //to set cursor at the end of textbox
Its another way to declare the constructor. You can also use the class name, for ex:
class Cat
{
function Cat()
{
echo 'meow';
}
}
and
class Cat
{
function __construct()
{
echo 'meow';
}
}
Are equivalent. They are called whenever a new instance of the class is created, in this case, they will be called with this line:
$cat = new Cat();
There are detailed notes on this that helped me completely, located here.
Jonathon Reinhart has already answered with the key bit, to edit /etc/gitlab/gitlab.rb, alter the external_url and then run sudo gitlab-ctl reconfigure; sudo gitlab-ctl restart
However I needed to go a bit further and docs I linked above explained it. So what I ended up with looks like:
external_url 'https://gitlab.toilethumor.com'
nginx['ssl_certificate'] = "/www/ssl/star_toilethumor.com-chained.crt"
nginx['ssl_certificate_key'] = "/www/ssl/star_toilethumor.com.key"
nginx['proxy_set_headers'] = {
"X-Forwarded-Proto" => "http",
"CUSTOM_HEADER" => "VALUE"
}
Above, I've explicitly declared where my SSL goodies are on this server. And that's of course followed by
sudo gitlab-ctl reconfigure
sudo gitlab-ctl restart
Also, when you switch the omnibus package to https, the bundled nginx will only serve on port 443. Since all my stuff is reached via reverse proxy, this part was potentially significant.
As I went through this, I screwed something up and it helpful to find the actual nginx logs, this lead me there:
sudo gitlab-ctl tail nginx
on windows invoke "cmd /k start http://www.example.com" Infact you can always invoke "default" programs using the start command. For ex start abc.mp3 will invoke the default mp3 player and load the requested mp3 file.
Another point of view (based on more fundamental mathematical topics)
The most general computing platform is a Turing Machine.
There is a problem with the Turing machine. All the input/output data stays inside the turing machine. In the real world there are input sources and output sinks external to our Turing machine, and in general governed by systems outside of our control. That is, those external system will send/receive data at will in any format with any desired data-scheduler.
Question: How do we manage to make independent turing-machines speak to each other in the most-general way so that each turing-machine sees their peers as either a source of input-data or sink of output-data?
Answer: Using something like camel, mule, BizTalk or any other ESB that abstract away the data handling between completing distinct "physical" (or virtual software) turing machines.
Going forward, the new HTML Intersection Observer API is the thing you're looking for. It allows you to configure a callback that is called whenever one element, called the target, intersects either the device viewport or a specified element. It's available in latest versions of Chrome, Firefox and Edge. See https://developer.mozilla.org/en-US/docs/Web/API/Intersection_Observer_API for more info.
Simple code example for observing display:none switching:
// Start observing visbility of element. On change, the
// the callback is called with Boolean visibility as
// argument:
function respondToVisibility(element, callback) {
var options = {
root: document.documentElement,
};
var observer = new IntersectionObserver((entries, observer) => {
entries.forEach(entry => {
callback(entry.intersectionRatio > 0);
});
}, options);
observer.observe(element);
}

You've specifically mentioned a "variable-length array" in your question, so neither of the existing two answers (as I write this) are quite right.
Java doesn't have any concept of a "variable-length array", but it does have Collections, which serve in this capacity. Any collection (technically any "Iterable", a supertype of Collections) can be looped over as simply as this:
Collection<Thing> things = ...;
for (Thing t : things) {
System.out.println(t);
}
EDIT: it's possible I misunderstood what he meant by 'variable-length'. He might have just meant it's a fixed length but not every instance is the same fixed length. In which case the existing answers would be fine. I'm not sure what was meant.

You can use perl to replace various characters, for example:
$ echo "Hello\ world" | perl -pe 's/\\/\\\\/g'
Hello\\ world
Depending on the nature of your escape, you can chain multiple calls to escape the proper characters.
The size_t
type is meant to specify the size of something so it's natural to use it, for example, getting the length of a string and then processing each character:
for (size_t i = 0, max = strlen (str); i < max; i++)
doSomethingWith (str[i]);
You do have to watch out for boundary conditions of course, since it's an unsigned type. The boundary at the top end is not usually that important since the maximum is usually large (though it is possible to get there). Most people just use an int
for that sort of thing because they rarely have structures or arrays that get big enough to exceed the capacity of that int
.
But watch out for things like:
for (size_t i = strlen (str) - 1; i >= 0; i--)
which will cause an infinite loop due to the wrapping behaviour of unsigned values (although I've seen compilers warn against this). This can also be alleviated by the (slightly harder to understand but at least immune to wrapping problems):
for (size_t i = strlen (str); i-- > 0; )
By shifting the decrement into a post-check side-effect of the continuation condition, this does the check for continuation on the value before decrement, but still uses the decremented value inside the loop (which is why the loop runs from len .. 1
rather than len-1 .. 0
).
if ($.inArray('yourElement', yourArray) > -1)
{
//yourElement in yourArray
//code here
}
Reference: Jquery Array
The $.inArray() method is similar to JavaScript's native .indexOf() method in that it returns -1 when it doesn't find a match. If the first element within the array matches value, $.inArray() returns 0.
There isn't one built in, but it's simple to roll your own, as demonstrated here:
import operator
def prod(factors):
return reduce(operator.mul, factors, 1)
See answers to this question:
Which Python module is suitable for data manipulation in a list?
The Natural Language Toolkit (nltk.org) has what you need. This group posting indicates this does it:
import nltk.data
tokenizer = nltk.data.load('tokenizers/punkt/english.pickle')
fp = open("test.txt")
data = fp.read()
print '\n-----\n'.join(tokenizer.tokenize(data))
(I haven't tried it!)
You need to put the files into an array in order to sort and find the last modified file.
$files = array();
if ($handle = opendir('.')) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
$files[filemtime($file)] = $file;
}
}
closedir($handle);
// sort
ksort($files);
// find the last modification
$reallyLastModified = end($files);
foreach($files as $file) {
$lastModified = date('F d Y, H:i:s',filemtime($file));
if(strlen($file)-strpos($file,".swf")== 4){
if ($file == $reallyLastModified) {
// do stuff for the real last modified file
}
echo "<tr><td><input type=\"checkbox\" name=\"box[]\"></td><td><a href=\"$file\" target=\"_blank\">$file</a></td><td>$lastModified</td></tr>";
}
}
}
Not tested, but that's how to do it.
It's incorrect syntax that causes MySQL to think you're trying to do something with a column or parameter that has the incorrect type "DOUBLE".
In my case I updated the varchar column in a table setting NULL
where the value 0
stood. My update query was like this:
UPDATE myTable SET myValue = NULL WHERE myValue = 0;
Now, since the actual type of myValue
is VARCHAR(255)
this gives the warning:
+---------+------+-----------------------------------------------+
| Level | Code | Message |
+---------+------+-----------------------------------------------+
| Warning | 1292 | Truncated incorrect DOUBLE value: 'value xyz' |
+---------+------+-----------------------------------------------+
And now myTable
is practically empty, because myValue
is now NULL
for EVERY ROW in the table! How did this happen?
*internal screaming*
Over 30k rows now have missing data.
*internal screaming intensifies*
Thank goodness for backups. I was able to recover all the data.
*internal screaming intensity lowers*
The corrected query is as follows:
UPDATE myTable SET myValue = NULL WHERE myValue = '0';
^^^
Quotation here!
I wish this was more than just a warning so it's less dangerous to forget those quotes.
*End internal screaming*
You can plot multiple subplots of multiple pandas data frames using matplotlib with a simple trick of making a list of all data frame. Then using the for loop for plotting subplots.
Working code:
import matplotlib.pyplot as plt
import pandas as pd
import numpy as np
# dataframe sample data
df1 = pd.DataFrame(np.random.rand(10,2)*100, columns=['A', 'B'])
df2 = pd.DataFrame(np.random.rand(10,2)*100, columns=['A', 'B'])
df3 = pd.DataFrame(np.random.rand(10,2)*100, columns=['A', 'B'])
df4 = pd.DataFrame(np.random.rand(10,2)*100, columns=['A', 'B'])
df5 = pd.DataFrame(np.random.rand(10,2)*100, columns=['A', 'B'])
df6 = pd.DataFrame(np.random.rand(10,2)*100, columns=['A', 'B'])
#define number of rows and columns for subplots
nrow=3
ncol=2
# make a list of all dataframes
df_list = [df1 ,df2, df3, df4, df5, df6]
fig, axes = plt.subplots(nrow, ncol)
# plot counter
count=0
for r in range(nrow):
for c in range(ncol):
df_list[count].plot(ax=axes[r,c])
count=+1
Using this code you can plot subplots in any configuration. You need to just define number of rows nrow
and number of columns ncol
. Also, you need to make list of data frames df_list
which you wanted to plot.
You CAN ONLY understand Domain driven design by first comprehending what the following are:
What is a domain?
The field for which a system is built. Airport management, insurance sales, coffee shops, orbital flight, you name it.
It's not unusual for an application to span several different domains. For example, an online retail system might be working in the domains of shipping (picking appropriate ways to deliver, depending on items and destination), pricing (including promotions and user-specific pricing by, say, location), and recommendations (calculating related products by purchase history).
What is a model?
"A useful approximation to the problem at hand." -- Gerry Sussman
An Employee class is not a real employee. It models a real employee. We know that the model does not capture everything about real employees, and that's not the point of it. It's only meant to capture what we are interested in for the current context.
Different domains may be interested in different ways to model the same thing. For example, the salary department and the human resources department may model employees in different ways.
What is a domain model?
A model for a domain.
What is Domain-Driven Design (DDD)?
It is a development approach that deeply values the domain model and connects it to the implementation. DDD was coined and initially developed by Eric Evans.

ORDER BY alters the order in which items are returned.
GROUP BY will aggregate records by the specified columns which allows you to perform aggregation functions on non-grouped columns (such as SUM, COUNT, AVG, etc).
You can use \centering

Your question title mentions Blocking Queues. However, ConcurrentLinkedQueue
is not a blocking queue.
The BlockingQueue
s are ArrayBlockingQueue
, DelayQueue
, LinkedBlockingDeque
, LinkedBlockingQueue
, PriorityBlockingQueue
, and SynchronousQueue
.
Some of these are clearly not fit for your purpose (DelayQueue
, PriorityBlockingQueue
, and SynchronousQueue
). LinkedBlockingQueue
and LinkedBlockingDeque
are identical, except that the latter is a double-ended Queue (it implements the Deque interface).
Since ArrayBlockingQueue
is only useful if you want to limit the number of elements, I'd stick to LinkedBlockingQueue
.
Expanding on First Zero's answer, I'm guess you want something where you can also run gradle build
without errors.
Both gradle build
and gradle -PmainClass=foo runApp
work with this:
task runApp(type:JavaExec) {
classpath = sourceSets.main.runtimeClasspath
main = project.hasProperty("mainClass") ? project.getProperty("mainClass") : "package.MyDefaultMain"
}
where you set your default main class.
public class NetworkChangeReceiver extends BroadcastReceiver {
@Override
public void onReceive(final Context context, final Intent intent) {
if (checkInternet(context)) {
Toast.makeText(context, "Network Available Do operations", Toast.LENGTH_LONG).show();
}
}
boolean checkInternet(Context context) {
ServiceManager serviceManager = new ServiceManager(context);
return serviceManager.isNetworkAvailable()
}
}
ServiceManager.java
public class ServiceManager {
Context context;
public ServiceManager(Context base) {
context = base;
}
public boolean isNetworkAvailable() {
ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = cm.getActiveNetworkInfo();
return networkInfo != null && networkInfo.isConnected();
}
}
permissions:
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
It's worth noting that the distinct
keyword in HQL does not map directly to the distinct
keyword in SQL.
If you use the distinct
keyword in HQL, then sometimes Hibernate will use the distinct
SQL keyword, but in some situations it will use a result transformer to produce distinct results. For example when you are using an outer join like this:
select distinct o from Order o left join fetch o.lineItems
It is not possible to filter out duplicates at the SQL level in this case, so Hibernate uses a ResultTransformer
to filter duplicates after the SQL query has been performed.
The addEdge is trusting more than the correction of the addNode method. It's also trusting that the addNode method has been invoked by other method. I'd recommend to include check if m is not null.
Your query should work fine, but you have to use the alias parent
to show the values of the parent table like this:
select
CONCAT(user.user_fname, ' ', user.user_lname) AS 'User Name',
CONCAT(parent.user_fname, ' ', parent.user_lname) AS 'Parent Name'
from users as user
inner join users as parent on parent.user_parent_id = user.user_id
where user.user_id = $_GET[id];
style="overflow: hidden"
and style="resize: none"
were the ones that did the trick.
I needed to get the element as a string.
jQuery("#bob").get(0).outerHTML;
Which will give you something like:
<input type="text" id="bob" value="hello world" />
...as a string rather than a DOM element.
If this thread is to be believed, you need to supply the -ffunction-sections
and -fdata-sections
to gcc, which will put each function and data object in its own section. Then you give and --gc-sections
to GNU ld to remove the unused sections.
Yes, It's possible with DOUBLE STASH
git stash --keep-index
. This command will create a stash with ALL of your changes (staged and unstaged), but will leave the staged changes in your working directory (still in state staged).git stash push -m "good stash"
"good stash"
has ONLY staged files. Now if you need unstaged files before stash, simply apply first stash (the one created with --keep-index
) and now you can remove files you stashed to "good stash"
.

From practical standpoint just one minor digression:
import torch
dev = torch.device("cuda") if torch.cuda.is_available() else torch.device("cpu")
This dev
now knows if cuda or cpu.
And there is a difference how you deal with model and with tensors when moving to cuda. It is a bit strange at first.
import torch
import torch.nn as nn
dev = torch.device("cuda") if torch.cuda.is_available() else torch.device("cpu")
t1 = torch.randn(1,2)
t2 = torch.randn(1,2).to(dev)
print(t1) # tensor([[-0.2678, 1.9252]])
print(t2) # tensor([[ 0.5117, -3.6247]], device='cuda:0')
t1.to(dev)
print(t1) # tensor([[-0.2678, 1.9252]])
print(t1.is_cuda) # False
t1 = t1.to(dev)
print(t1) # tensor([[-0.2678, 1.9252]], device='cuda:0')
print(t1.is_cuda) # True
class M(nn.Module):
def __init__(self):
super().__init__()
self.l1 = nn.Linear(1,2)
def forward(self, x):
x = self.l1(x)
return x
model = M() # not on cuda
model.to(dev) # is on cuda (all parameters)
print(next(model.parameters()).is_cuda) # True
This all is tricky and understanding it once, helps you to deal fast with less debugging.
Maybe because its 2013-01-29 so +1 month would be 2013-02-29 which doesn't exist so it would be 2013-03-01
You could try
date('m/d/y h:i a',(strtotime('next month',strtotime(date('m/01/y')))));

If you like to have the timestamp without the timezone but local timezone do
git log -1 --format=%cd --date=local

While LIKE
is suitable for this case, a more general purpose solution is to use instr
, which doesn't require characters in the search string to be escaped. Note: instr
is available starting from Sqlite 3.7.15.
SELECT *
FROM TABLE
WHERE instr(column, 'cats') > 0;
Also, keep in mind that LIKE
is case-insensitive, whereas instr
is case-sensitive.
SELECT * from table where field in (SELECT distinct field from table)

String is immutable, meaning that when you perform an operation on a String you are really creating a whole new String.
StringBuffer is mutable, and you can append to it as well as reset its length to 0.
In practice, the compiler seems to use StringBuffer during String concatenation for performance reasons.
WordUtils.capitalizeFully(str)
from apache commons-lang has the exact semantics as required.
OpenSSL is quite difficult. It's easy to accidentally throw away all your security by not doing negotiation exactly right. (Heck, I've been personally bitten by a bug where curl wasn't reading the OpenSSL alerts exactly right, and couldn't talk to some sites.)

Is it possible to restart a single container
Not through kubectl
, although depending on the setup of your cluster you can "cheat" and docker kill the-sha-goes-here
, which will cause kubelet to restart the "failed" container (assuming, of course, the restart policy for the Pod says that is what it should do)
how do I restart the pod
That depends on how the Pod was created, but based on the Pod name you provided, it appears to be under the oversight of a ReplicaSet, so you can just kubectl delete pod test-1495806908-xn5jn
and kubernetes will create a new one in its place (the new Pod will have a different name, so do not expect kubectl get pods
to return test-1495806908-xn5jn
ever again)
For me the problem was the port. I first incorrectly used port 465, which works for SSL
but not TLS
. So the key thing was changing the port to 587.

Using your code with some random data, this would work:
fig, axs = plt.subplots(2,5, figsize=(15, 6), facecolor='w', edgecolor='k')
fig.subplots_adjust(hspace = .5, wspace=.001)
axs = axs.ravel()
for i in range(10):
axs[i].contourf(np.random.rand(10,10),5,cmap=plt.cm.Oranges)
axs[i].set_title(str(250+i))
The layout is off course a bit messy, but that's because of your current settings (the figsize, wspace etc).
The problem here is that the rendering of a RadioButtonList wraps the individual radio buttons (ListItems) in span tags and even when you assign a client-side event handler to the list item directly using Attributes it assigns the event to the span. Assigning the event to the RadioButtonList assigns it to the table it renders in.
The trick here is to add the ListItems on the aspx page and not from the code behind. You can then assign the JavaScript function to the onClick property. This blog post; attaching client-side event handler to radio button list by Juri Strumpflohner explains it all.
This only works if you know the ListItems in advance and does not help where the items in the RadioButtonList need to be dynamically added using the code behind.
None of the above worked for me. what worked for me is to go to File -> Invalidate Caches / Restart

Usually if you need a connection pool you are writing an application that runs in some managed environment, that is you are running inside an application server. If this is the case be sure to check what connection pooling facilities your application server providesbefore trying any other options.
The out-of-the box solution will be the best integrated with the rest of the application servers facilities. If however you are not running inside an application server I would recommend the Apache Commons DBCP Component. It is widely used and provides all the basic pooling functionality most applications require.
$keys = array_keys($arr);
$keys = rsort($keys);
print $keys[0];

I usually use numpy sum over the logical condition column:

>>> np.sum(df['Age'] > 20)

This seems to me slightly shorter than the solution presented above

select.html('');
$.each(data, function(id, option) {
select.append($('<option></option>').val(option.value).html(option.name));
});

It works well with jQuery 1.4.1.
For complete article for using dynamic lists with ASP.NET MVC & jQuery visit:
Unlike the C#/.NET class library (and most other sensible languages), when you pass a String
in as the string-to-match argument to the string.replace
method, it doesn't do a string replace. It converts the string to a RegExp
and does a regex substitution. As Gumbo explains, a regex substitution requires the g
?lobal flag, which is not on by default, to replace all matches in one go.
If you want a real string-based replace — for example because the match-string is dynamic and might contain characters that have a special meaning in regexen — the JavaScript idiom for that is:
var id= 'c_'+date.split('/').join('');
I got this error recently by introducing an old plugin to wordpress. It loaded an older version of jquery, which happened to be placed before the jquery mouse file. There was no jquery widget file loaded with the second version, which caused the error.
No error for using the extra jquery library -- that's a problem especially if a silent fail might have happened, causing a not so silent fail later on.
A potential way around it for wordpress might be to be explicit about the dependencies that way the jquery mouse would follow the widget which would follow the correct core leaving the other jquery to be loaded afterwards. Still might cause a production error later if you don't catch that and change the default function for jquery for the second version in all the files associated with it.

To keep the promise chain going, you can't use setTimeout()
the way you did because you aren't returning a promise from the .then()
handler - you're returning it from the setTimeout()
callback which does you no good.
Instead, you can make a simple little delay function like this:
function delay(t, v) {
return new Promise(function(resolve) {
setTimeout(resolve.bind(null, v), t)
});
}
And, then use it like this:
getLinks('links.txt').then(function(links){
let all_links = (JSON.parse(links));
globalObj=all_links;
return getLinks(globalObj["one"]+".txt");
}).then(function(topic){
writeToBody(topic);
// return a promise here that will be chained to prior promise
return delay(1000).then(function() {
return getLinks(globalObj["two"]+".txt");
});
});
Here you're returning a promise from the .then()
handler and thus it is chained appropriately.
You can also add a delay method to the Promise object and then directly use a .delay(x)
method on your promises like this:
function delay(t, v) {_x000D_
return new Promise(function(resolve) { _x000D_
setTimeout(resolve.bind(null, v), t)_x000D_
});_x000D_
}_x000D_
_x000D_
Promise.prototype.delay = function(t) {_x000D_
return this.then(function(v) {_x000D_
return delay(t, v);_x000D_
});_x000D_
}_x000D_
_x000D_
_x000D_
Promise.resolve("hello").delay(500).then(function(v) {_x000D_
console.log(v);_x000D_
});
_x000D_
Or, use the Bluebird promise library which already has the .delay()
method built-in.
In Python 3 and Python 2.7+, dictionary comprehensions look like the below:
d = {k:v for k, v in iterable}
For Python 2.6 or earlier, see fortran's answer.
You can use .match && join() methods. .match() returns an array and .join() makes a string
function digitsBeGone(str){
return str.match(/\D/g).join('')
}
There is also a really simple way to do this with the help of the RecursiveTreeIterator
class, answered here: https://stackoverflow.com/a/37548504/2032235
A filter argument with a trailing * can be evaluated almost instantaneously via an index lookup. A leading * implies a sequential search through the index, so it is O(N). It will take ages.
I suggest you reconsider the requirement.
Use log4j in your java program instead. Then you can output to multiple media, create rolling logs, etc. and include timestamps, class names and line numbers.
Edited: Kindly note that whereBetween('date',$start_date,$end_date)
is inclusive of the first date.
The advantage of lists appears if you need to insert items in the middle and don't want to start resizing the array and shifting things around.
You're correct in that this is typically not the case. I've had a few very specific cases like that, but not too many.
Functional and immutable approach, without .filter
and without creating more objects than needed
Object.keys(obj).reduce((acc, key) => (obj[key] === undefined ? acc : {...acc, [key]: obj[key]}), {})
Let me give an example for Including express module with require & import
-require
var express = require('express');
-import
import * as express from 'express';
So after using any of the above statement we will have a variable called as 'express' with us. Now we can define 'app' variable as,
var app = express();
So we use 'require' with 'CommonJS' and 'import' with 'ES6'.
For more info on 'require' & 'import', read through below links.
require - Requiring modules in Node.js: Everything you need to know
import - An Update on ES6 Modules in Node.js
For ES6/ES2015 you can import directly like:
// example.json
{
"name": "testing"
}
// ES6/ES2015
// app.js
import * as data from './example.json';
const {name} = data;
console.log(name); // output 'testing'
If you use Typescript, you may declare json module like:
// tying.d.ts
declare module "*.json" {
const value: any;
export default value;
}
Since Typescript 2.9+ you can add --resolveJsonModule compilerOptions in tsconfig.json
{
"compilerOptions": {
"target": "es5",
...
"resolveJsonModule": true,
...
},
...
}
The following command will work for you, if you want to change default path. Just type this in bin directory of mongodb.
mongod --dbpath=yourdirectory\data\db
In case you want to move existing data too, then just copy all the folders from existing data\db directory to new directory before you execute the command.
And also stop existing mongodb services which are running.
As abernier pointed out, there is a recommended solution in the GNU make manual, which uses a 'fake' target to force rebuilding of a target:
clean: FORCE
rm $(objects)
FORCE: ;
This will run clean, regardless of any other dependencies.
I added the semicolon to the solution from the manual, otherwise an empty line is required.
If you are lost with errors like module not found there is noway other the than following method if you have used react native CLI.I had faced similar issue as a result of openning xcode project from .xcodeproj file instead of .xcworkspace. Also please note that react-native eject only for Expo project.
The only workaround to regenarate ios and android folders within a react native project is the following.
Now your problem should be solved
Another idea is to use clipToOutline
property of an ImageView
.
Here is an example layout:
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Simple view to draw borders for an image,
borders will be rounded because of the oval-shaped background. -->
<View
android:id="@+id/v_border"
android:layout_width="50dp"
android:layout_height="50dp"
android:background="@drawable/shape_border"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<!-- Image itself: fits the border view,
a margin serves as a border width;
the key point here - is a background shape which will clip the view to its forms. -->
<ImageView
android:id="@+id/iv_image"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_margin="4dp"
android:background="@drawable/shape_oval"
android:src="@mipmap/ic_launcher"
app:layout_constraintBottom_toBottomOf="@+id/v_border"
app:layout_constraintEnd_toEndOf="@+id/v_border"
app:layout_constraintStart_toStartOf="@+id/v_border"
app:layout_constraintTop_toTopOf="@+id/v_border" />
</androidx.constraintlayout.widget.ConstraintLayout>
And here are our shape_border
drawable:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval">
<solid android:color="#FF00FF" />
</shape>
And shape_oval
drawable:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval" />
The only thing you should do in the code - is to enable clipToOutline
property:
binding.ivImage.clipToOutline = true
And of course you can avoid even this line of the code with some BindingAdapter.
If anyone else simply wants to display a black image as a background, here e.g. for 500x500 px:
import cv2
import numpy as np
black_screen = np.zeros([500,500,3])
cv2.imshow("Simple_black", black_screen)
cv2.waitKey(0)
Without explicitly defining the height
I determined I need to apply the flex
value to the parent and grandparent div
elements...
<div style="display: flex;">
<div style="display: flex;">
<img alt="No, he'll be an engineer." src="theknack.png" style="margin: auto;" />
</div>
</div>
If you're using a single element (e.g. dead-centered text in a single flex
element) use the following:
align-items: center;
display: flex;
justify-content: center;
In case of multi monitor and If you prefer to center on correct monitor/screen then you might like to try these lines:
// Save values for future(for example, to center a form on next launch)
int screen_x = Screen.FromControl(Form).WorkingArea.X;
int screen_y = Screen.FromControl(Form).WorkingArea.Y;
// Move it and center using correct screen/monitor
Form.Left = screen_x;
Form.Top = screen_y;
Form.Left += (Screen.FromControl(Form).WorkingArea.Width - Form.Width) / 2;
Form.Top += (Screen.FromControl(Form).WorkingArea.Height - Form.Height) / 2;
Use the Microsoft Anti-XSS library which includes a JavaScript encode.
In applied usage for the Asynchronous IO coroutine, yield from
has a similar behavior as await
in a coroutine function. Both of which is used to suspend the execution of coroutine.
yield from
is used by the generator-based coroutine.
For Asyncio, if there's no need to support an older Python version (i.e. >3.5), async def
/await
is the recommended syntax to define a coroutine. Thus yield from
is no longer needed in a coroutine.
But in general outside of asyncio, yield from <sub-generator>
has still some other usage in iterating the sub-generator as mentioned in the earlier answer.
Giving another answer, because my edits of other answers where rejected.
This is the most concise and simple answer (similar to Garret Hall's)
File("filename").writeAll("hello world")
This is similar to Jus12, but without the verbosity and with correct code style
def using[A <: {def close(): Unit}, B](resource: A)(f: A => B): B =
try f(resource) finally resource.close()
def writeToFile(path: String, data: String): Unit =
using(new FileWriter(path))(_.write(data))
def appendToFile(path: String, data: String): Unit =
using(new PrintWriter(new FileWriter(path, true)))(_.println(data))
Note you do NOT need the curly braces for try finally
, nor lambdas, and note usage of placeholder syntax. Also note better naming.
Keep it simple
dataGridView1.Columns.Add("newColumnName", "Column Name in Text");
To add rows
dataGridView1.Rows.Add("Value for column#1"); // [,"column 2",...]
If you NPM those modules you can serve them using static redirect.
First install the packages:
npm install jquery
npm install bootstrap
Then on the server.js:
var express = require('express');
var app = express();
// prepare server
app.use('/api', api); // redirect API calls
app.use('/', express.static(__dirname + '/www')); // redirect root
app.use('/js', express.static(__dirname + '/node_modules/bootstrap/dist/js')); // redirect bootstrap JS
app.use('/js', express.static(__dirname + '/node_modules/jquery/dist')); // redirect JS jQuery
app.use('/css', express.static(__dirname + '/node_modules/bootstrap/dist/css')); // redirect CSS bootstrap
Then, finally, at the .html:
<link rel="stylesheet" href="/css/bootstrap.min.css">
<script src="/js/jquery.min.js"></script>
<script src="/js/bootstrap.min.js"></script>
I would not serve pages directly from the folder where your server.js file is (which is usually the same as node_modules) as proposed by timetowonder, that way people can access your server.js file.
Of course you can simply download and copy & paste on your folder, but with NPM you can simply update when needed... easier, I think.
Find control into Repeater (Header, Item, Footer)
public static class FindControlInRepeater
{
public static Control FindControl(this Repeater repeater, string controlName)
{
for (int i = 0; i < repeater.Controls.Count; i++)
if (repeater.Controls[i].Controls[0].FindControl(controlName) != null)
return repeater.Controls[i].Controls[0].FindControl(controlName);
return null;
}
}
This may not be exactly on target because I am not completely clear on what you want to do. However, assuming you mean you want to assign a different class to a div in response to an event, the answer is yes, you can certainly do this with jQuery. I am only a jQuery beginner, but I have used the following in my code:
$(document).ready(function() {
$("#someElementID").click(function() { // this is your event
$("#divID").addClass("second"); // here your adding the new class
)};
)};
If you wanted to replace the first class with the second class, I believe you would use removeClass first and then addClass as I did above. toggleClass may also be worth a look. The jQuery documentation is well written for these type of changes, with examples.
Someone else my have a better option, but I hope that helps!
Your model should implement an interface IValidatableObject
. Put your validation code in Validate
method:
public class MyModel : IValidatableObject
{
public string Title { get; set; }
public string Description { get; set; }
public IEnumerable<ValidationResult> Validate(ValidationContext validationContext)
{
if (Title == null)
yield return new ValidationResult("*", new [] { nameof(Title) });
if (Description == null)
yield return new ValidationResult("*", new [] { nameof(Description) });
}
}
Please notice: this is a server-side validation. It doesn't work on client-side. You validation will be performed only after form submission.
In Jersey Rest Services just use the JacksonFeatures annotation ...
@JacksonFeatures(serializationDisable = {SerializationFeature.FAIL_ON_EMPTY_BEANS})
public Response getSomething() {
Object entity = doSomething();
return Response.ok(entity).build();
}
If you want to write the output to a file you can use the stdout-argument of subprocess.call
.
It takes None
, subprocess.PIPE
, a file object or a file descriptor. The first is the default, stdout is inherited from the parent (your script). The second allows you to pipe from one command/process to another. The third and fourth are what you want, to have the output written to a file.
You need to open a file with something like open
and pass the object or file descriptor integer to call
:
f = open("blah.txt", "w")
subprocess.call(["/home/myuser/run.sh", "/tmp/ad_xml", "/tmp/video_xml"], stdout=f)
I'm guessing any valid file-like object would work, like a socket (gasp :)), but I've never tried.
As marcog mentions in the comments you might want to redirect stderr as well, you can redirect this to the same location as stdout with stderr=subprocess.STDOUT
. Any of the above mentioned values works as well, you can redirect to different places.
Martin's solution is very similar to mine, however how would you handle a default descriptions when the desired translation isn't found ?
Would that require an IFNULL() and another SELECT statement for each field ?
The default translation would be stored in the same table, where a flag like "isDefault" indicates wether that description is the default description in case none has been found for the current language.
It's quite an old topic, but since it is returned when searching for "django list field" I'll share the custom django list field code I modified to work with Python 3 and Django 2. It supports the admin interface now and not uses eval (which is a huge security breach in Prashant Gaur's code).
from django.db import models
from typing import Iterable
class ListField(models.TextField):
"""
A custom Django field to represent lists as comma separated strings
"""
def __init__(self, *args, **kwargs):
self.token = kwargs.pop('token', ',')
super().__init__(*args, **kwargs)
def deconstruct(self):
name, path, args, kwargs = super().deconstruct()
kwargs['token'] = self.token
return name, path, args, kwargs
def to_python(self, value):
class SubList(list):
def __init__(self, token, *args):
self.token = token
super().__init__(*args)
def __str__(self):
return self.token.join(self)
if isinstance(value, list):
return value
if value is None:
return SubList(self.token)
return SubList(self.token, value.split(self.token))
def from_db_value(self, value, expression, connection):
return self.to_python(value)
def get_prep_value(self, value):
if not value:
return
assert(isinstance(value, Iterable))
return self.token.join(value)
def value_to_string(self, obj):
value = self.value_from_object(obj)
return self.get_prep_value(value)
Try the format syntax:
print ("{0}. {1} appears {2} times.".format(1, 'b', 3.1415))
Outputs:
1. b appears 3.1415 times.
The print function is called just like any other function, with parenthesis around all its arguments.
When I understand this correctly, you replace the default constructor with a parameterized one and therefore have to describe the JSON keys which are used to call the constructor with.
How to specify the JDK version?
Use any of three ways: (1) Spring Boot feature, or use Maven compiler plugin with either (2) source
& target
or (3) with release
.
<java.version>
is not referenced in the Maven documentation.
It is a Spring Boot specificity.
It allows to set the source and the target java version with the same version such as this one to specify java 1.8 for both :
Feel free to use it if you use Spring Boot.
maven-compiler-plugin
with source
& target
maven-compiler-plugin
or maven.compiler.source
/maven.compiler.target
properties are equivalent.That is indeed :
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
</plugins>
is equivalent to :
<properties>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
</properties>
according to the Maven documentation of the compiler plugin
since the <source>
and the <target>
elements in the compiler configuration use the properties maven.compiler.source
and maven.compiler.target
if they are defined.
The
-source
argument for the Java compiler.
Default value is:1.6
.
User property is:maven.compiler.source
.
The
-target
argument for the Java compiler.
Default value is:1.6
.
User property is:maven.compiler.target
.
About the default values for source
and target
, note that
since the 3.8.0
of the maven compiler, the default values have changed from 1.5
to 1.6
.
maven-compiler-plugin
with release
instead of source
& target
The maven-compiler-plugin 3.6
and later versions provide a new way :
You could also declare just :
<properties>
<maven.compiler.release>9</maven.compiler.release>
</properties>
But at this time it will not work as the maven-compiler-plugin
default version you use doesn't rely on a recent enough version.
The Maven release
argument conveys release
: a new JVM standard option that we could pass from Java 9 :
Compiles against the public, supported and documented API for a specific VM version.
This way provides a standard way to specify the same version for the source
, the target
and the bootstrap
JVM options.
Note that specifying the bootstrap
is a good practice for cross compilations and it will not hurt if you don't make cross compilations either.
Which is the best way to specify the JDK version?
The first way (<java.version>
) is allowed only if you use Spring Boot.
For Java 8 and below :
About the two other ways : valuing the maven.compiler.source
/maven.compiler.target
properties or using the maven-compiler-plugin
, you can use one or the other. It changes nothing in the facts since finally the two solutions rely on the same properties and the same mechanism : the maven core compiler plugin.
Well, if you don't need to specify other properties or behavior than Java versions in the compiler plugin, using this way makes more sense as this is more concise:
<properties>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
</properties>
From Java 9 :
The release
argument (third point) is a way to strongly consider if you want to use the same version for the source and the target.
What happens if the version differs between the JDK in JAVA_HOME and which one specified in the pom.xml?
It is not a problem if the JDK referenced by the JAVA_HOME
is compatible with the version specified in the pom but to ensure a better cross-compilation compatibility think about adding the bootstrap
JVM option with as value the path of the rt.jar
of the target
version.
An important thing to consider is that the source
and the target
version in the Maven configuration should not be superior to the JDK version referenced by the JAVA_HOME
.
A older version of the JDK cannot compile with a more recent version since it doesn't know its specification.
To get information about the source, target and release supported versions according to the used JDK, please refer to java compilation : source, target and release supported versions.
How handle the case of JDK referenced by the JAVA_HOME is not compatible with the java target and/or source versions specified in the pom?
For example, if your JAVA_HOME
refers to a JDK 1.7 and you specify a JDK 1.8 as source and target in the compiler configuration of your pom.xml, it will be a problem because as explained, the JDK 1.7 doesn't know how to compile with.
From its point of view, it is an unknown JDK version since it was released after it.
In this case, you should configure the Maven compiler plugin to specify the JDK in this way :
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.8</source>
<target>1.8</target>
<compilerVersion>1.8</compilerVersion>
<fork>true</fork>
<executable>D:\jdk1.8\bin\javac</executable>
</configuration>
</plugin>
You could have more details in examples with maven compiler plugin.
It is not asked but cases where that may be more complicated is when you specify source but not target. It may use a different version in target according to the source version. Rules are particular : you can read about them in the Cross-Compilation Options part.
Why the compiler plugin is traced in the output at the execution of the Maven package
goal even if you don't specify it in the pom.xml?
To compile your code and more generally to perform all tasks required for a maven goal, Maven needs tools. So, it uses core Maven plugins (you recognize a core Maven plugin by its groupId
: org.apache.maven.plugins
) to do the required tasks : compiler plugin for compiling classes, test plugin for executing tests, and so for... So, even if you don't declare these plugins, they are bound to the execution of the Maven lifecycle.
At the root dir of your Maven project, you can run the command : mvn help:effective-pom
to get the final pom effectively used. You could see among other information, attached plugins by Maven (specified or not in your pom.xml), with the used version, their configuration and the executed goals for each phase of the lifecycle.
In the output of the mvn help:effective-pom
command, you could see the declaration of these core plugins in the <build><plugins>
element, for example :
...
<plugin>
<artifactId>maven-clean-plugin</artifactId>
<version>2.5</version>
<executions>
<execution>
<id>default-clean</id>
<phase>clean</phase>
<goals>
<goal>clean</goal>
</goals>
</execution>
</executions>
</plugin>
<plugin>
<artifactId>maven-resources-plugin</artifactId>
<version>2.6</version>
<executions>
<execution>
<id>default-testResources</id>
<phase>process-test-resources</phase>
<goals>
<goal>testResources</goal>
</goals>
</execution>
<execution>
<id>default-resources</id>
<phase>process-resources</phase>
<goals>
<goal>resources</goal>
</goals>
</execution>
</executions>
</plugin>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<executions>
<execution>
<id>default-compile</id>
<phase>compile</phase>
<goals>
<goal>compile</goal>
</goals>
</execution>
<execution>
<id>default-testCompile</id>
<phase>test-compile</phase>
<goals>
<goal>testCompile</goal>
</goals>
</execution>
</executions>
</plugin>
...
You can have more information about it in the introduction of the Maven lifeycle in the Maven documentation.
Nevertheless, you can declare these plugins when you want to configure them with other values as default values (for example, you did it when you declared the maven-compiler plugin in your pom.xml to adjust the JDK version to use) or when you want to add some plugin executions not used by default in the Maven lifecycle.
Update (1/10/2018):
For Spark 2.2+ the best way to do this is probably using the to_date
or to_timestamp
functions, which both support the format
argument. From the docs:
>>> from pyspark.sql.functions import to_timestamp
>>> df = spark.createDataFrame([('1997-02-28 10:30:00',)], ['t'])
>>> df.select(to_timestamp(df.t, 'yyyy-MM-dd HH:mm:ss').alias('dt')).collect()
[Row(dt=datetime.datetime(1997, 2, 28, 10, 30))]
Original Answer (for Spark < 2.2)
It is possible (preferrable?) to do this without a udf:
from pyspark.sql.functions import unix_timestamp, from_unixtime
df = spark.createDataFrame(
[("11/25/1991",), ("11/24/1991",), ("11/30/1991",)],
['date_str']
)
df2 = df.select(
'date_str',
from_unixtime(unix_timestamp('date_str', 'MM/dd/yyy')).alias('date')
)
print(df2)
#DataFrame[date_str: string, date: timestamp]
df2.show(truncate=False)
#+----------+-------------------+
#|date_str |date |
#+----------+-------------------+
#|11/25/1991|1991-11-25 00:00:00|
#|11/24/1991|1991-11-24 00:00:00|
#|11/30/1991|1991-11-30 00:00:00|

If i remember correctly, you need to use the "Shapes" property of your sheet.
Each Shape object has a TopLeftCell and BottomRightCell attributes that tell you the position of the image.
Here's a piece of code i used a while ago, roughly adapted to your needs. I don't remember the specifics about all those ChartObjects and whatnot, but here it is:
For Each oShape In ActiveSheet.Shapes
strImageName = ActiveSheet.Cells(oShape.TopLeftCell.Row, 1).Value
oShape.Select
'Picture format initialization
Selection.ShapeRange.PictureFormat.Contrast = 0.5: Selection.ShapeRange.PictureFormat.Brightness = 0.5: Selection.ShapeRange.PictureFormat.ColorType = msoPictureAutomatic: Selection.ShapeRange.PictureFormat.TransparentBackground = msoFalse: Selection.ShapeRange.Fill.Visible = msoFalse: Selection.ShapeRange.Line.Visible = msoFalse: Selection.ShapeRange.Rotation = 0#: Selection.ShapeRange.PictureFormat.CropLeft = 0#: Selection.ShapeRange.PictureFormat.CropRight = 0#: Selection.ShapeRange.PictureFormat.CropTop = 0#: Selection.ShapeRange.PictureFormat.CropBottom = 0#: Selection.ShapeRange.ScaleHeight 1#, msoTrue, msoScaleFromTopLeft: Selection.ShapeRange.ScaleWidth 1#, msoTrue, msoScaleFromTopLeft
'/Picture format initialization
Application.Selection.CopyPicture
Set oDia = ActiveSheet.ChartObjects.Add(0, 0, oShape.Width, oShape.Height)
Set oChartArea = oDia.Chart
oDia.Activate

.ChartArea.Select
.Paste
.Export ("H:\Webshop_Zpider\Strukturbildene\" & strImageName & ".jpg")

Postgres hasn't implemented an equivalent to INSERT OR REPLACE
. From the ON CONFLICT
docs (emphasis mine):
It can be either DO NOTHING, or a DO UPDATE clause specifying the exact details of the UPDATE action to be performed in case of a conflict.
Though it doesn't give you shorthand for replacement, ON CONFLICT DO UPDATE
applies more generally, since it lets you set new values based on preexisting data. For example:
INSERT INTO users (id, level)
VALUES (1, 0)
ON CONFLICT (id) DO UPDATE
SET level = users.level + 1;
If you do not want to change the display format permanently, and perhaps apply a new format later on, I personally favour the use of a resource manager (the with
statement in Python). In your case you could do something like this:
with pd.option_context('display.float_format', '${:0.2f}'.format):
print(df)
If you happen to need a different format further down in your code, you can change it by varying just the format in the snippet above.
I know it is old but if you want to get this from an URL you could simply use:
document.location.pathname.substring(document.location.pathname.lastIndexOf('/.') + 1);
document.location.pathname
gets the pathname from the current URL.
lastIndexOf
get the index of the last occurrence of the following Regex, in our case is /.
. The dot means any character, thus, it will not count if the /
is the last character on the URL.
substring
will cut the string between two indexes.
One solution to this is to do what msysGit's rebasing merge script does - after the rebase, merge in the old head of feature
with -s ours
. You end up with the commit graph:
A--B--C------F--G (master)
\ \
\ D'--E' (feature)
\ /
\ --
\ /
D--E (old-feature)
... and your push of feature
will be a fast-forward.
In other words, you can do:
git checkout feature
git branch old-feature
git rebase master
git merge -s ours old-feature
git push origin feature
(Not tested, but I think that's right...)
You can use date
to get time and date of a day:
[pengyu@GLaDOS ~]$date
Tue Aug 27 15:01:27 CST 2013
Also hwclock
would do:
[pengyu@GLaDOS ~]$hwclock
Tue 27 Aug 2013 03:01:29 PM CST -0.516080 seconds
For customized output, you can either redirect the output of date
to something like awk
, or write your own program to do that.
Remember to put your own executable scripts/binary into your PATH
(e.g. /usr/bin) to make it invokable anywhere.
I think that what you want to do is turn the JSON string back into an object when it arrives back in your XMLHttpRequest - correct?
If so, you need to eval the string to turn it into a JavaScript object - note that this can be unsafe as you're trusting that the JSON string isn't malicious and therefore executing it. Preferably you could use jQuery's parseJSON
.parent {
margin:0 auto;
width:700px;
border:2px solid red;
}
.child {
position:absolute;
width:100%;
border:2px solid blue;
left:0;
top:200px;
}
You can use a dictionary comprehension.
d = {k:d[k] for k in d if d[k] != val}
It looks like you have accidentally declared DataType
as an array rather than as a string.
Change line 3 to:
Dim DataType As String = myTableData.Rows(i).Item(1)
That should work.
I recommend installing the custom_error_message gem (or as a plugin) originally written by David Easley
It lets you do stuff like:
validates_presence_of :non_friendly_field_name, :message => "^Friendly field name is blank"
You have to call close()
on the GZIPOutputStream
before you attempt to read it. The final bytes of the file will only be written when the file is actually closed. (This is irrespective of any explicit buffering in the output stack. The stream only knows to compress and write the last bytes when you tell it to close. A flush()
probably won't help ... though calling finish()
instead of close()
should work. Look at the javadocs.)
Here's the correct code (in Java);
package test;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.zip.GZIPInputStream;
import java.util.zip.GZIPOutputStream;
public class GZipTest {
public static void main(String[] args) throws
FileNotFoundException, IOException {
String name = "/tmp/test";
GZIPOutputStream gz = new GZIPOutputStream(new FileOutputStream(name));
gz.write(10);
gz.close(); // Remove this to reproduce the reported bug
System.out.println(new GZIPInputStream(new FileInputStream(name)).read());
}
}
(I've not implemented resource management or exception handling / reporting properly as they are not relevant to the purpose of this code. Don't treat this as an example of "good code".)
A PowerShell script based on @Mithrl's answer
# export_env.ps1
$Date = Get-Date
$DateStr = '{0:dd-MM-yyyy}' -f $Date
mkdir -Force $PWD\env_exports | Out-Null
regedit /e "$PWD\env_exports\user_env_variables[$DateStr].reg" "HKEY_CURRENT_USER\Environment"
regedit /e "$PWD\env_exports\global_env_variables[$DateStr].reg" "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment"
In this step I have Set the variable first:
<c:set var="structureId" value="<%=article.getStructureId()%>" scope="request"></c:set>
In this step I have checked the variable empty or not:
<c:if test="${not empty structureId }">
<a href="javascript:void(0);">Change Design</a>
</c:if>
@Xeon06, nice but just as a fyi for those that read this thread and tried like me...
when returning the array from php => json_encode($theArray)
. converts to a string which to me isn't easy to manipulate esp for soft js users like myself.
Inside js, you are trying to get the array values and/or keys of the array u r better off using JSON.parse as in var jsArray = JSON.parse(data)
where data is return array from php. the json encoded string is converted to js object that can now be manipulated easily.
e.g. foo={one:1, two:2, three:3} - gotten after JSON.parse
for (key in foo){ console.log("foo["+ key +"]="+ foo[key]) }
- prints to ur firebug console. voila!
public static void main(String args[])
{
Scanner s = new Scanner(System.in);
System.out.println("Press enter to continue.....");
s.nextLine();
}
This nextline
is a pretty good option as it will help us run next line whenever the enter key is pressed.
static void Main()
{
for (int i=0; i<GetNames().Length; i++)
{
Console.WriteLine (GetNames()[i]);
}
}
static string[] GetNames()
{
string[] ret = {"Answer", "by", "Anonymous", "Pakistani"};
return ret;
}
Could write a udf and take a value to tell it which day of the week should be 1 would look like this (drawing on answer from John to use MOD instead of CASE):
DROP FUNCTION IF EXISTS `reporting`.`udfDayOfWeek`;
DELIMITER |
CREATE FUNCTION `reporting`.`udfDayOfWeek` (
_date DATETIME,
_firstDay TINYINT
) RETURNS tinyint(4)
FUNCTION_BLOCK: BEGIN
DECLARE _dayOfWeek, _offset TINYINT;
SET _offset = 8 - _firstDay;
SET _dayOfWeek = (DAYOFWEEK(_date) + _offset) MOD 7;
IF _dayOfWeek = 0 THEN
SET _dayOfWeek = 7;
END IF;
RETURN _dayOfWeek;
END FUNCTION_BLOCK
To call this function to give you the current day of week value when your week starts on a Tuesday for instance, you'd call:
SELECT udfDayOfWeek(NOW(), 3);
Nice thing about having it as a udf is you could also call it on a result set field like this:
SELECT
udfDayOfWeek(p.SignupDate, 3) AS SignupDayOfWeek,
p.FirstName,
p.LastName
FROM Profile p;
For strings you can just after process the string. For docstrings you need to after process the function instead. Here is a solution for both that is still readable.

may be used.
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

Invariant's answer is a good resource for how everything was started and what was the state of JavaFX on embedded and mobile in beginning of 2014. But, a lot has changed since then and the users who stumble on this thread do not get the updated information.
Most of my points are related to Invariant's answer, so I would suggest to go through it first.
UPDATE
JavaFXPorts has been deprecated. Gluon Mobile now uses GraalVM underneath. There are multiple advantages of using GraalVM. Please check this blogpost from Gluon. The IDE plugins have been updated to use Gluon Client plugins which leverages GraalVM to AOT compile applications for Android/iOS.
Old answer with JavaFXPorts
Some bad news first:
Now, some good news:
If you are not the DIY kind, I would suggest to install the IDE plugin on your favourite IDE and get started.
Most of the documentation on how to get started can be found here and some of the samples can be found here.
The same situation occurred when I was using VSCode with eslint. If you use VSCode,
1 - Click area that name can be both LF or CRLF where at the bottom right of the VScode.
2 - Select LF from the drop-down menu.
That's worked for me.
I haven't found any way to do that in Android Studio, but I access the db with a remote shell instead of pulling the file each time.
Find all info here: http://developer.android.com/tools/help/sqlite3.html
1- Go to your platform-tools folder in a command prompt
2- Enter the command adb devices
to get the list of your devices
C:\Android\adt-bundle-windows-x86_64\sdk\platform-tools>adb devices
List of devices attached
emulator-xxxx device
3- Connect a shell to your device:
C:\Android\adt-bundle-windows-x86_64\sdk\platform-tools>adb -s emulator-xxxx shell
4a- You can bypass this step on rooted device
run-as <your-package-name>
4b- Navigate to the folder containing your db file:
cd data/data/<your-package-name>/databases/
5- run sqlite3 to connect to your db:
sqlite3 <your-db-name>.db
6- run sqlite3 commands that you like eg:
Select * from table1 where ...;
Note: Find more commands to run below.
There are a few steps to see the tables in an SQLite database:
List the tables in your database:
.tables
List how the table looks:
.schema tablename
Print the entire table:
SELECT * FROM tablename;
List all of the available SQLite prompt commands:
.help
Convert both completed
and total
to double
or at least cast them to double
when doing the devision. I.e. cast the varaibles to double not just the result.
Fair warning, there is a floating point precision problem when working with float
and double
.
I had the same problem, in fact, I juste forgot to run the service after installation ..
Start mysql server :

StringBuilder
is faster than StringBuffer
because it's not synchronized
.
Here's a simple benchmark test:
public class Main {
public static void main(String[] args) {
int N = 77777777;
long t;
{
StringBuffer sb = new StringBuffer();
t = System.currentTimeMillis();
for (int i = N; i --> 0 ;) {
sb.append("");
}
System.out.println(System.currentTimeMillis() - t);
}
{
StringBuilder sb = new StringBuilder();
t = System.currentTimeMillis();
for (int i = N; i > 0 ; i--) {
sb.append("");
}
System.out.println(System.currentTimeMillis() - t);
}
}
}
A test run gives the numbers of 2241 ms
for StringBuffer
vs 753 ms
for StringBuilder
.
Kotlin solution using context extension
fun Context.applyNewLocale(locale: Locale): Context {
val config = this.resources.configuration
val sysLocale = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
config.locales.get(0)
} else {
//Legacy
config.locale
}
if (sysLocale.language != locale.language) {
Locale.setDefault(locale)
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
config.setLocale(locale)
} else {
//Legacy
config.locale = locale
}
resources.updateConfiguration(config, resources.displayMetrics)
}
return this

First make sure you are in markdown edit model in the ipython notebook cell
This is an alternative way to the method proposed by others <img src="myimage.png">
:
![title](img/picture.png)
It also seems to work if the title is missing:
![](img/picture.png)
Note no quotations should be in the path. Not sure if this works for paths with white spaces though!
Alternatively, if you do not wish to push to a repository:
Export the container to a tarball
docker export <CONTAINER ID> > /home/export.tar
Move your tarball to new machine
Import it back
cat /home/export.tar | docker import - some-name:latest
Your question is a little unclear. If you're generating hostDict
in a loop:
with open('data.txt', 'a') as outfile:
for hostDict in ....:
json.dump(hostDict, outfile)
outfile.write('\n')
If you mean you want each variable within hostDict
to be on a new line:
with open('data.txt', 'a') as outfile:
json.dump(hostDict, outfile, indent=2)
When the indent
keyword argument is set it automatically adds newlines.
Same concept as a .jar
file in Java, it is a .zip
file with some metadata files renamed .egg
, for distributing code as bundles.
Specifically: The Internal Structure of Python Eggs
A "Python egg" is a logical structure embodying the release of a specific version of a Python project, comprising its code, resources, and metadata. There are multiple formats that can be used to physically encode a Python egg, and others can be developed. However, a key principle of Python eggs is that they should be discoverable and importable. That is, it should be possible for a Python application to easily and efficiently find out what eggs are present on a system, and to ensure that the desired eggs' contents are importable.
The
.egg
format is well-suited to distribution and the easy uninstallation or upgrades of code, since the project is essentially self-contained within a single directory or file, unmingled with any other projects' code or resources. It also makes it possible to have multiple versions of a project simultaneously installed, such that individual programs can select the versions they wish to use.
When people talk about HTML5 applications they're most likely talking about writing just a simple web page or embedding a web page into their app (which will essentially provide the user interface). For the later there are different frameworks available, e.g. PhoneGap. These are used to provide more than the default browser features (e.g. multi touch) as well as allowing the app to run seamingly "standalone" and without the browser's navigation bars etc.
You can add a JAR which having above specified class exist e.g.ojdbc jar which supported by installed java version, also make sure that you have added it into classpath.
The method returns a list that contains 3 element first is year, second is month and end element is day:
public static List<int> GetDurationInEnglish(DateTime from, DateTime to)
{
try
{
if (from > to)
return null;
var fY = from.Year;
var fM = from.Month;
var fD = DateTime.DaysInMonth(fY, fM);
var tY = to.Year;
var tM = to.Month;
var tD = DateTime.DaysInMonth(tY, tM);
int dY = 0;
int dM = 0;
int dD = 0;
if (fD > tD)
{
tM--;
if (tM <= 0)
{
tY--;
tM = 12;
tD += DateTime.DaysInMonth(tY, tM);
}
else
{
tD += DateTime.DaysInMonth(tY, tM);
}
}
dD = tD - fD;
if (fM > tM)
{
tY--;
tM += 12;
}
dM = tM - fM;
dY = tY - fY;
return new List<int>() { dY, dM, dD };
}
catch (Exception exception)
{
//todo: log exception with parameters in db
return null;
}
}
