The CSS :first-child
selector allows you to target an element that is the first child element within its parent.
element:first-child { style_properties }
table:first-child { style_properties }
We show up two functions that prints a SINGLE character to binary.
void printbinchar(char character)
{
char output[9];
itoa(character, output, 2);
printf("%s\n", output);
}
printbinchar(10) will write into the console
1010
itoa is a library function that converts a single integer value to a string with the specified base. For example... itoa(1341, output, 10) will write in output string "1341". And of course itoa(9, output, 2) will write in the output string "1001".
The next function will print into the standard output the full binary representation of a character, that is, it will print all 8 bits, also if the higher bits are zero.
void printbincharpad(char c)
{
for (int i = 7; i >= 0; --i)
{
putchar( (c & (1 << i)) ? '1' : '0' );
}
putchar('\n');
}
printbincharpad(10) will write into the console
00001010
Now i present a function that prints out an entire string (without last null character).
void printstringasbinary(char* s)
{
// A small 9 characters buffer we use to perform the conversion
char output[9];
// Until the first character pointed by s is not a null character
// that indicates end of string...
while (*s)
{
// Convert the first character of the string to binary using itoa.
// Characters in c are just 8 bit integers, at least, in noawdays computers.
itoa(*s, output, 2);
// print out our string and let's write a new line.
puts(output);
// we advance our string by one character,
// If our original string was "ABC" now we are pointing at "BC".
++s;
}
}
Consider however that itoa don't adds padding zeroes, so printstringasbinary("AB1") will print something like:
1000001
1000010
110001
If you just run jmap -histo:live or jmap -histo, it outputs the contents on the console!
If you run into this issue in a fairly complex app it can be cumbersome to refactor all your imports. PyCharm offers a quickfix for this that will automatically change all usage of the imported symbols as well.
Well, in Java, a variable can be final not just as a parameter, but as a class-level field, like
public class Test
{
public final int a = 3;
or as a local variable, like
public static void main(String[] args)
{
final int a = 3;
If you want to access and modify a variable from an anonymous class, you might want to make the variable a class-level variable in the enclosing class.
public class Test
{
public int a;
public void doSomething()
{
Runnable runnable =
new Runnable()
{
public void run()
{
System.out.println(a);
a = a+1;
}
};
}
}
You can't have a variable as final and give it a new value. final
means just that: the value is unchangeable and final.
And since it's final, Java can safely copy it to local anonymous classes. You're not getting some reference to the int (especially since you can't have references to primitives like int in Java, just references to Objects).
It just copies over the value of a into an implicit int called a in your anonymous class.
Another option (just so you've seen it):
$(function () {
$(".inputs").click(function (e) {
alert(e.target.id);
});
});
HTH.
I use this solution for responsive boxes of different rations:

width: 100%; height: 100%;
top: 0;right: 0;bottom: 0;left: 0;
position: absolute;
}
.box {
position: relative;
width: 100%;
}
.box::before {
content: "";
display: block;
padding-top: 100%; /*square for no ratio*/
}
.ratio1_1::before { padding-top: 100%; }
.ratio1_2::before { padding-top: 200%; }
.ratio2_1::before { padding-top: 50%; }
.ratio4_3::before { padding-top: 75%; }
.ratio16_9::before { padding-top: 56.25%; }

I will go with ParentNode.children:
As it provides namedItem
method that allows me directly to get one of the children elements without looping through all children or avoiding to use getElementById
etc.
e.g.
ParentNode.children.namedItem('ChildElement-ID'); // JS
ref.current.children.namedItem('ChildElement-ID'); // React
this.$refs.ref.children.namedItem('ChildElement-ID'); // Vue
I will go with Node.childNodes:
As it provides forEach
method when I work with window.IntersectionObserver
e.g.
nodeList.forEach((node) => { observer.observe(node) })
// IE11 does not support forEach on nodeList, but easy to be polyfilled.
On Chrome 83
Node.childNodes provides
entries
,forEach
,item
,keys
,length
andvalues
ParentNode.children provides

To update this for Python-3 you can do this
"{} {}".format(True, False)
However if you want to actually format the string (e.g. add white space), you encounter Python casting the boolean into the underlying C value (i.e. an int), e.g.
>>> "{:<8} {}".format(True, False)
'1 False'
To get around this you can cast True
as a string, e.g.
>>> "{:<8} {}".format(str(True), False)
'True False'
First off, EC2 and Elastic Compute Cloud are the same thing.
Next, AWS encompasses the range of Web Services that includes EC2 and Elastic Beanstalk. It also includes many others such as S3, RDS, DynamoDB, and all the others.
EC2 is Amazon's service that allows you to create a server (AWS calls these instances) in the AWS cloud. You pay by the hour and only what you use. You can do whatever you want with this instance as well as launch n
number of instances.
Elastic Beanstalk is one layer of abstraction away from the EC2 layer. Elastic Beanstalk will setup an "environment" for you that can contain a number of EC2 instances, an optional database, as well as a few other AWS components such as a Elastic Load Balancer, Auto-Scaling Group, Security Group. Then Elastic Beanstalk will manage these items for you whenever you want to update your software running in AWS. Elastic Beanstalk doesn't add any cost on top of these resources that it creates for you. If you have 10 hours of EC2 usage, then all you pay is 10 compute hours.
For running Wordpress, it is whatever you are most comfortable with. You could run it straight on a single EC2 instance, you could use a solution from the AWS Marketplace, or you could use Elastic Beanstalk.
In the case that you want to reduce system operations and just focus on the website, then Elastic Beanstalk would be the best choice for that. Elastic Beanstalk supports a PHP stack (as well as others). You can keep your site in version control and easily deploy to your environment whenever you make changes. It will also setup an Autoscaling group which can spawn up more EC2 instances if traffic is growing.
Here's the first result off of Google when searching for "elastic beanstalk wordpress": https://www.otreva.com/blog/deploying-wordpress-amazon-web-services-aws-ec2-rds-via-elasticbeanstalk/

I think Semaphore is what you are looking for, it will block the main process after counting down to 0. Sample code:
from multiprocessing import Process
from multiprocessing import Semaphore
import time
def f(name, sema):
print('process {} starting doing business'.format(name))
# simulate a time-consuming task by sleeping
time.sleep(5)
# `release` will add 1 to `sema`, allowing other
# processes blocked on it to continue
sema.release()
if __name__ == '__main__':
concurrency = 20
total_task_num = 1000
sema = Semaphore(concurrency)
all_processes = []
for i in range(total_task_num):
# once 20 processes are running, the following `acquire` call
# will block the main process since `sema` has been reduced
# to 0. This loop will continue only after one or more
# previously created processes complete.
sema.acquire()
p = Process(target=f, args=(i, sema))
all_processes.append(p)
p.start()
# inside main process, wait for all processes to finish
for p in all_processes:
p.join()
The following code is more structured since it acquires and releases sema
in the same function. However, it will consume too much resources if total_task_num
is very large:
from multiprocessing import Process
from multiprocessing import Semaphore
import time
def f(name, sema):
print('process {} starting doing business'.format(name))
# `sema` is acquired and released in the same
# block of code here, making code more readable,
# but may lead to problem.
sema.acquire()
time.sleep(5)
sema.release()
if __name__ == '__main__':
concurrency = 20
total_task_num = 1000
sema = Semaphore(concurrency)
all_processes = []
for i in range(total_task_num):
p = Process(target=f, args=(i, sema))
all_processes.append(p)
# the following line won't block after 20 processes
# have been created and running, instead it will carry
# on until all 1000 processes are created.
p.start()
# inside main process, wait for all processes to finish
for p in all_processes:
p.join()
The above code will create total_task_num
processes but only concurrency
processes will be running while other processes are blocked, consuming precious system resources.
By itself, document.activeElement
can still return an element if the document isn't focused (and thus nothing in the document is focused!)
You may want that behavior, or it may not matter (e.g. within a keydown
event), but if you need to know something is actually focused, you can additionally check document.hasFocus()
.
The following will give you the focused element if there is one, or else null
.
var focused_element = null;
if (
document.hasFocus() &&
document.activeElement !== document.body &&
document.activeElement !== document.documentElement
) {
focused_element = document.activeElement;
}
To check whether a specific element has focus, it's simpler:
var input_focused = document.activeElement === input && document.hasFocus();
To check whether anything is focused, it's more complex again:
var anything_is_focused = (
document.hasFocus() &&
document.activeElement !== null &&
document.activeElement !== document.body &&
document.activeElement !== document.documentElement
);
Robustness Note: In the code where it the checks against document.body
and document.documentElement
, this is because some browsers return one of these or null
when nothing is focused.
It doesn't account for if the <body>
(or maybe <html>
) had a tabIndex
attribute and thus could actually be focused. If you're writing a library or something and want it to be robust, you should probably handle that somehow.
Here's a (heavy airquotes) "one-liner" version of getting the focused element, which is conceptually more complicated because you have to know about short-circuiting, and y'know, it obviously doesn't fit on one line, assuming you want it to be readable.
I'm not gonna recommend this one. But if you're a 1337 hax0r, idk... it's there.
You could also remove the || null
part if you don't mind getting false
in some cases. (You could still get null
if document.activeElement
is null
):
var focused_element = (
document.hasFocus() &&
document.activeElement !== document.body &&
document.activeElement !== document.documentElement &&
document.activeElement
) || null;
For checking if a specific element is focused, alternatively you could use events, but this way requires setup (and potentially teardown), and importantly, assumes an initial state:
var input_focused = false;
input.addEventListener("focus", function() {
input_focused = true;
});
input.addEventListener("blur", function() {
input_focused = false;
});
You could fix the initial state assumption by using the non-evented way, but then you might as well just use that instead.
Yes, that will work as you expect it to. Unfortunately, I seem to be having trouble to find an explicit statement of this in the MySQL manual.
Foreign keys mean the value must exist in the other table. NULL refers to the absence of value, so when you set a column to NULL, it wouldn't make sense to try to enforce constraints on that.

In my case I was using a JDK 8 client and the server was using insecure old ciphers. The server is Apache and I added this line to the Apache config:

I came across this question, and the answers here didn't work for me; i couldn't figure out why i can't login and got the above error.
It turns out that postgresql saves usernames lowercase, but during authentication it uses both upper- and lowercase.
CREATE USER myNewUser WITH PASSWORD 'passWord';
will create a user with the username 'mynewuser' and password 'passWord'.
This means you have to authenticate with 'mynewuser', and not with 'myNewUser'. For a newbie in pgsql like me, this was confusing. I hope it helps others who run into this problem.
Sometimes changing the header is not enough, some sites check the referer as well:
curl -v \
-H 'Host: restapi.some-site.com' \
-H 'Connection: keep-alive' \
-H 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8' \
-H 'Accept-Language: en-GB,en-US;q=0.8,en;q=0.6' \
-e localhost \
-A 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.65 Safari/537.36' \
'http://restapi.some-site.com/getsomething?argument=value&argument2=value'
In this example the referer (-e or --referer in curl) is 'localhost'.

As Nikola pointed out in the comment below, in case the backup URL is invalid as well, some browsers will trigger the "error" event again which will result in an infinite loop. We can guard against this by simply nullifying the "error" handler via this.onerror=null;
.
Here's a sample class:
public class Increment
{
public static void main(String [] args)
{
for (int i = 0; i < args.length; ++i)
{
System.out.println(args[i]);
}
}
}
If I disassemble this class using javap.exe I get this:
Compiled from "Increment.java"
public class Increment extends java.lang.Object{
public Increment();
Code:
0: aload_0
1: invokespecial #1; //Method java/lang/Object."<init>":()V
4: return
public static void main(java.lang.String[]);
Code:
0: iconst_0
1: istore_1
2: iload_1
3: aload_0
4: arraylength
5: if_icmpge 23
8: getstatic #2; //Field java/lang/System.out:Ljava/io/PrintStream;
11: aload_0
12: iload_1
13: aaload
14: invokevirtual #3; //Method java/io/PrintStream.println:(Ljava/lang/String;)V
17: iinc 1, 1
20: goto 2
23: return
}
If I change the loop so it uses i++ and disassemble again I get this:
Compiled from "Increment.java"
public class Increment extends java.lang.Object{
public Increment();
Code:
0: aload_0
1: invokespecial #1; //Method java/lang/Object."<init>":()V
4: return
public static void main(java.lang.String[]);
Code:
0: iconst_0
1: istore_1
2: iload_1
3: aload_0
4: arraylength
5: if_icmpge 23
8: getstatic #2; //Field java/lang/System.out:Ljava/io/PrintStream;
11: aload_0
12: iload_1
13: aaload
14: invokevirtual #3; //Method java/io/PrintStream.println:(Ljava/lang/String;)V
17: iinc 1, 1
20: goto 2
23: return
}
When I compare the two, TextPad tells me that the two are identical.
What this says is that from the point of view of the generated byte code there's no difference in a loop. In other contexts there is a difference between ++i and i++, but not for loops.

return;
}
if ([[segue identifier] isEqualToString:SEGUE_IDENTIFIER_FAVORITE]) {
// ...
return;
}
}
Here is a simplified version of the 2-step approach using build and commit, without shell scripts. It involves:
With relatively minor changes the additional step adds only a few seconds to the build time.
Basically:
docker build -t image-name . # your normal docker build
# Now run a command in a throwaway container that uses volumes and makes changes:
docker run -v /some:/volume --name temp-container image-name /some/post-configure/command
# Replace the original image with the result:
# (reverting CMD to whatever it was, otherwise it will be set to /some/post-configure/command)
docker commit --change="CMD bash" temp-container image-name
# Delete the temporary container:
docker rm temp-container
In my use case I want to pre-generate a maven toolchains.xml file, but my many JDK installations are on a volume that isn't available until runtime. Some of my images are not compatible with all the JDKS, so I need to test compatibility at build time and populate toolchains.xml conditionally. Note that I don't need the image to be portable, I'm not publishing it to Docker Hub.
There are 2 inputs you might have and you can also convert between them.
example: [{"":{"...
The pd.DataFrame() needs a listOfDictionaries as input.
example: '{"":{"...
If you have jsonStr, you need an extra step to listOfDictionaries first. This is obvious as it is generated like:
jsonStr = json.dumps(listOfDictionaries)
Thus, switch back from jsonStr to listOfDictionaries first:
listOfDictionaries = json.loads(jsonStr)
Using jQuery only (no UI library/plugin). Even jQuery can be easily eliminated

for(var i=50; i<=100; i=i+0.1){ //i represents the lightness
d += 10;
(function(ii,dd){
setTimeout(function(){
$('tr').eq(1).css('backgroundColor','hsl(0,100%,'+ii+'%)');
}, dd);
})(i,d);

Make variables are not exported into the environment of processes make invokes... by default. However you can use make's export

to this:
test: export NODE_ENV = test

2) You need to set the size of each div with the text and button so that each of these divs have the same height. Then for your button:
button {
position: absolute;
bottom: 0;
}
Very easy, just wrap the table in a div that has overflow-y:scroll;
and overflow-x:scroll
properties, and make the div have a width and length smaller than the table.
IT WILL WORK!!!
You can use this, pithy. :D
TextBox1.Focus();
TextBox1.Select(0, TextBox1.Text.Length);
That should work:
>>> df = pd.DataFrame()
>>> data = pd.DataFrame({"A": range(3)})
>>> df.append(data)
A

But the append
doesn't happen in-place, so you'll have to store the output if you want it:

Index: []
>>> df = df.append(data)
>>> df

You can get the first of the month, by calculating the last_day of the month before and add one day. It is awkward, but I think it is better than formatting a date as string and use that for calculation.
select

yourtable t
where
/* Greater or equal to the start of last month */
t.date >= DATE_ADD(LAST_DAY(DATE_SUB(NOW(), INTERVAL 2 MONTH)), INTERVAL 1 DAY) and
/* Smaller or equal than one month ago */
t.date <= DATE_SUB(NOW(), INTERVAL 1 MONTH)

You can get the desired effect by (and this also cleans up the original plotting code):
ggplot(data = datos, aes(x = fecha)) +
geom_line(aes(y = TempMax, colour = "TempMax")) +
geom_line(aes(y = TempMedia, colour = "TempMedia")) +
geom_line(aes(y = TempMin, colour = "TempMin")) +
scale_colour_manual("",
breaks = c("TempMax", "TempMedia", "TempMin"),
values = c("red", "green", "blue")) +
xlab(" ") +
scale_y_continuous("Temperatura (C)", limits = c(-10,40)) +
labs(title="TITULO")
The idea is that each line is given a color by mapping the colour
aesthetic to a constant string. Choosing the string which is what you want to appear in the legend is the easiest. The fact that in this case it is the same as the name of the y
variable being plotted is not significant; it could be any set of strings. It is very important that this is inside the aes
call; you are creating a mapping to this "variable".
scale_colour_manual
can now map these strings to the appropriate colors. The result is
In some cases, the mapping between the levels and colors needs to be made explicit by naming the values in the manual scale (thanks to @DaveRGP for pointing this out):
ggplot(data = datos, aes(x = fecha)) +
geom_line(aes(y = TempMax, colour = "TempMax")) +
geom_line(aes(y = TempMedia, colour = "TempMedia")) +
geom_line(aes(y = TempMin, colour = "TempMin")) +
scale_colour_manual("",
values = c("TempMedia"="green", "TempMax"="red",
"TempMin"="blue")) +
xlab(" ") +
scale_y_continuous("Temperatura (C)", limits = c(-10,40)) +
labs(title="TITULO")
(giving the same figure as before). With named values, the breaks can be used to set the order in the legend and any order can be used in the values.
ggplot(data = datos, aes(x = fecha)) +
geom_line(aes(y = TempMax, colour = "TempMax")) +
geom_line(aes(y = TempMedia, colour = "TempMedia")) +
geom_line(aes(y = TempMin, colour = "TempMin")) +
scale_colour_manual("",
breaks = c("TempMedia", "TempMax", "TempMin"),
values = c("TempMedia"="green", "TempMax"="red",
"TempMin"="blue")) +
xlab(" ") +
scale_y_continuous("Temperatura (C)", limits = c(-10,40)) +

You can use dataSrc :
Here is a typical example of datatables.net
var table = $('#example').DataTable( {
"ajax": {
"type" : "GET",
"url" : "ajax.php",
"dataSrc": function ( json ) {
//Make your callback here.
alert("Done!");
return json.data;
}
},
"columns": [
{ "data": "name" },
{ "data": "position" },
{ "data": "office" },
{ "data": "extn" },
{ "data": "start_date" },
{ "data": "salary" }
]
} );
I have searched long and hard for an answer to this question. From what I gather Google did that on purpose once people used the internet connection to add spam comments to the market. However, I did find a guy who had done it and was willing to share the required images. The linked AVD runs(for me) both the market and browser internet.
NOTE: It looks like it's just going to fix the market. But the market won't run without internet, so if the market is fixed, the browser internet will work too. I downloaded the linked files myself and it showed the internet in the browser perfectly.
scrollHeight
is not only buggy, but doesn't work when your container has a hardcoded height (which is probably most cases, since you wanna get contents height without doing container.height()
itself)$('#outer')_x000D_
// Get children in array format, as we'll be reducing them into a single number_x000D_
.contents().toArray()_x000D_
// Filter out text and comment nodes, only allowing tags_x000D_
.filter(el => el.nodeType === 1)_x000D_
// Sum up all the children individual heights_x000D_
.reduce((accumulator, el) => $(el).outerHeight(true) + accumulator, 0);
_x000D_
Of course, this latter alternative only works when #outer
doesn't have immediate text childrens that take up space and you want to measure. Those are my 2 cents.
<div>
of which you can measure easily by doing $('#outer').children().height()
SOLUTION
As stated by others very well, HTTP_REFERER is set by the local machine of the user, specifically the browser, which means it's not reliable for security. However, this still is entirely the way in which Google Analytics monitors where you're getting your visitors from, so, it can actually be useful to check, exclude, include, etc..
If you think you should see an HTTP_REFERER and do not, add this to your PHP code, preferably at the top:
ini_set('session.referer_check', 'TRUE');
A more appropriate long-term solution, of course, is to actually update your php.ini or equivalent file. This is a nice and quick way of verifying, though.
TESTING
Run print($_SERVER['HTTP_REFERER']);
on your site, go to google.com, inspect some text, edit it to be <a href="https://example.com">LINK!</a>
, apply the change, then click the link. If it works, all is well and running precisely!
But maybe $_SERVER is wrong, or the test above says it's broken. Update your page with this, and then test again...
<script type="text/javascript">
console.log("REFER!" + document.referrer + "|" + location.referrer + "|");
</script>
USES
I use HTTP REFERER to block spam sites in GoogleAnalytics. Below is a graph focusing on one particular website's referrals. From 0 to 44 in one day, it wasn't caused by real users. It was caused by a botted site trying to get my attention to buy their services. But it just started because php.ini was updated to ignore the referer, which meant these spam, junk garbage sites were not getting their appropriate ERROR 403, "Access Denied."
Running JMeter in command line mode:

Now enter following command,
jmeter -n –t test.jmx
-n: specifies JMeter is to run in non-gui mode

Here is an example for all six boolean comparison operators (<, ==, >, >=, !=, <=):
BigDecimal big10 = new BigDecimal(10);
BigDecimal big20 = new BigDecimal(20);
System.out.println(big10.compareTo(big20) < -1); // false
System.out.println(big10.compareTo(big20) <= -1); // true
System.out.println(big10.compareTo(big20) == -1); // true
System.out.println(big10.compareTo(big20) >= -1); // true
System.out.println(big10.compareTo(big20) > -1); // false
System.out.println(big10.compareTo(big20) != -1); // false
System.out.println(big10.compareTo(big20) < 0); // true
System.out.println(big10.compareTo(big20) <= 0); // true
System.out.println(big10.compareTo(big20) == 0); // false
System.out.println(big10.compareTo(big20) >= 0); // false
System.out.println(big10.compareTo(big20) > 0); // false
System.out.println(big10.compareTo(big20) != 0); // true
System.out.println(big10.compareTo(big20) < 1); // true
System.out.println(big10.compareTo(big20) <= 1); // true
System.out.println(big10.compareTo(big20) == 1); // false
System.out.println(big10.compareTo(big20) >= 1); // false
System.out.println(big10.compareTo(big20) > 1); // false
System.out.println(big10.compareTo(big20) != 1); // true
I was able to figure it out. In case someone wants to know below the code that worked for me:
ASCIIEncoding ascii = new ASCIIEncoding();
byte[] byteArray = Encoding.UTF8.GetBytes(sOriginal);
byte[] asciiArray = Encoding.Convert(Encoding.UTF8, Encoding.ASCII, byteArray);
string finalString = ascii.GetString(asciiArray);
Let me know if there is a simpler way o doing it.
You can use the jQuery ajax method link if you want to pass data from client to server.
In this case you can use $_SERVER['HTTP_USER_AGENT']
variable to found browser user agent.
In all these scenarios outerScopeVar
is modified or assigned a value asynchronously or happening in a later time(waiting or listening for some event to occur),for which the current execution will not wait.So all these cases current execution flow results in outerScopeVar = undefined
Let's discuss each examples(I marked the portion which is called asynchronously or delayed for some events to occur):
1.
Here we register an eventlistner which will be executed upon that particular event.Here loading of image.Then the current execution continuous with next lines img.src = 'lolcat.png';
and alert(outerScopeVar);
meanwhile the event may not occur. i.e, funtion img.onload
wait for the referred image to load, asynchrously. This will happen all the folowing example- the event may differ.
2.
Here the timeout event plays the role, which will invoke the handler after the specified time. Here it is 0
, but still it registers an asynchronous event it will be added to the last position of the Event Queue
for execution, which makes the guaranteed delay.
3.
4.
Node can be consider as a king of asynchronous coding.Here the marked function is registered as a callback handler which will be executed after reading the specified file.
5.
Obvious promise (something will be done in future) is asynchronous. see What are the differences between Deferred, Promise and Future in JavaScript?
https://www.quora.com/Whats-the-difference-between-a-promise-and-a-callback-in-Javascript
Adding false after function will stop event propagation
<a (click)="foo(); false">click with stop propagation</a>
Just Add this simple css code in your style-sheet and you are ready to go.
.dropdown:hover > .dropdown-menu {
display: block;
}
.dropdown > .dropdown-toggle:active {
/*Without this, clicking will make it sticky*/
pointer-events: none;
}

You can check if you have any jumper wires plugged into pin 0 and 1. Those pins are used for serial communication and plugged wires can prevent the code from being uploaded on the board.
If nothing is plugged, it might be a bug with AVRDUDE, you can try updating it.
There are some good ideas in the existing answers, many work slightly differently and what you choose will also depend on which devices you target and what kind of look you're aiming to achieve. UITabBar
is notoriously unintuitive when it come to customizing its appearance, but here are a few more tricks that may help:
1). If you're looking to get rid of the glossy overlay for a more flat look do:
tabBar.backgroundColor = [UIColor darkGrayColor]; // this will be your background
[tabBar.subviews[0] removeFromSuperview]; // this gets rid of gloss
2). To set custom images to the tabBar buttons do something like:
for (UITabBarItem *item in tabBar.items){
[item setFinishedSelectedImage:selected withFinishedUnselectedImage:unselected];
[item setImageInsets:UIEdgeInsetsMake(6, 0, -6, 0)];
}
Where selected
and unselected
are UIImage
objects of your choice. If you'd like them to be a flat colour, the simplest solution I found is to create a UIView
with the desired backgroundColor
and then just render it into a UIImage
with the help of QuartzCore. I use the following method in a category on UIView
to get a UIImage
with the view's contents:
- (UIImage *)getImage {
UIGraphicsBeginImageContextWithOptions(self.bounds.size, NO, [[UIScreen mainScreen]scale]);
[[self layer] renderInContext:UIGraphicsGetCurrentContext()];
UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return viewImage;
}
3) Finally, you may want to customize the styling of the buttons' titles. Do:
for (UITabBarItem *item in tabBar.items){
[item setTitleTextAttributes: [NSDictionary dictionaryWithObjectsAndKeys:
[UIColor redColor], UITextAttributeTextColor,
[UIColor whiteColor], UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(0, 1)], UITextAttributeTextShadowOffset,
[UIFont boldSystemFontOfSize:18], UITextAttributeFont,
nil] forState:UIControlStateNormal];
}
This lets you do some adjustments, but still quite limited. Particularly, you cannot freely modify where the text is placed within the button, and cannot have different colours for selected/unselected buttons. If you want to do more specific text layout, just set UITextAttributeTextColor
to be clear and add your text into the selected
and unselected
images from part (2).
Or add "sort name" to list alphabetically
Get-ADPrincipalGroupMembership username | select name | sort name
Eventhough it is an old question, this may help someone.
We can choose multiple files while browsing for a file using "multiple"
<input type="file" name="datafile" size="40" multiple>
int myInt = System.Convert.ToInt32(myString);
As several others have mentioned, you can also use int.Parse()
and int.TryParse()
.
If you're certain that the string
will always be an int
:
int myInt = int.Parse(myString);
If you'd like to check whether string
is really an int
first:
int myInt;
bool isValid = int.TryParse(myString, out myInt); // the out keyword allows the method to essentially "return" a second value
if (isValid)
{
int plusOne = myInt + 1;
}
also you should click right button on mouse at your projectname and choose "open module settings" or press F4 button. Then on "dependencies" tab add your lib.jar to declare needed lib
Nope, this cannot be done since opacity
affects the whole element including its content and there's no way to alter this behavior. You can work around this with the two following methods.
Add another div
element to the container to hold the background. This is the most cross-browser friendly method and will work even on IE6.
HTML
<div class="myDiv">
<div class="bg"></div>
Hi there
</div>
CSS
.myDiv {
position: relative;
z-index: 1;
}
.myDiv .bg {
position: absolute;
z-index: -1;
top: 0;
bottom: 0;
left: 0;
right: 0;
background: url(test.jpg) center center;
opacity: .4;
width: 100%;
height: 100%;
}
Another trick is to use the CSS 2.1 :before
or CSS 3 ::before
pseudo-elements. :before
pseudo-element is supported in IE from version 8, while the ::before
pseudo-element is not supported at all. This will hopefully be rectified in version 10.
HTML
<div class="myDiv">
Hi there
</div>
CSS
.myDiv {
position: relative;
z-index: 1;
}
.myDiv:before {
content: "";
position: absolute;
z-index: -1;
top: 0;
bottom: 0;
left: 0;
right: 0;
background: url(test.jpg) center center;
opacity: .4;
}
Due to the behavior of z-index
you will have to set a z-index for the container as well as a negative z-index
for the background image.
See test case on jsFiddle:
Try to add empty View
inside horizontal LinearLayout
before element that you want to see right, e.g.:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<View
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_weight="1" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
I think you are after this:
CONVERT(datetime, date_as_string, 103)
Notice, that datetime
hasn't any format. You think about its presentation. To get the data of datetime
in an appropriate format you can use
CONVERT(varchar, date_as_datetime, 103)
Update:
MongoServer.Create
is obsolete now (thanks to @aknuds1). Instead this use following code:
var _server = new MongoClient(connectionString).GetServer();
It's easy. You should first take database name from connection string and then get database by name. Complete example:
var connectionString = "mongodb://localhost:27020/mydb";
//take database name from connection string
var _databaseName = MongoUrl.Create(connectionString).DatabaseName;
var _server = MongoServer.Create(connectionString);
//and then get database by database name:
_server.GetDatabase(_databaseName);
Important: If your database and auth database are different, you can add a authSource= query parameter to specify a different auth database. (thank you to @chrisdrobison)
NOTE If you are using the database segment as the initial database to use, but the username and password specified are defined in a different database, you can use the authSource option to specify the database in which the credential is defined. For example, mongodb://user:pass@hostname/db1?authSource=userDb would authenticate the credential against the userDb database instead of db1.
An easy way to format your domain objects to JSON is to use the Marshal Serializer.
Then pass the data to json_encode
and send the correct Content-Type header for your needs.
If you are using a framework like Symfony, you don't need to take care of setting the headers manually. There you can use the JsonResponse.
For example the correct Content-Type for dealing with Javascript would be application/javascript
.
Or if you need to support some pretty old browsers the safest would be text/javascript
.
For all other purposes like a mobile app use application/json
as the Content-Type.
Here is a small example:
<?php
...
$userCollection = [$user1, $user2, $user3];
$data = Marshal::serializeCollectionCallable(function (User $user) {
return [
'username' => $user->getUsername(),
'email' => $user->getEmail(),
'birthday' => $user->getBirthday()->format('Y-m-d'),
'followers => count($user->getFollowers()),
];
}, $userCollection);
header('Content-Type: application/json');
echo json_encode($data);
An RPC style web service uses the names of the method and its parameters to generate XML structures representing a method’s call stack. Document style indicates the SOAP body contains an XML document which can be validated against pre-defined XML schema document.

Assume you have one table with name 'table1'. It contain one column 'col1' with varchar type. Query to crate table is give below
CREATE TABLE `table1` (
`col1` VARCHAR(50) NULL DEFAULT NULL
)
Now if you want to insert number from 1 to 50 in that table then use following stored procedure
DELIMITER $$
CREATE PROCEDURE ABC()
BEGIN
DECLARE a INT Default 1 ;
simple_loop: LOOP
insert into table1 values(a);
SET a=a+1;
IF a=51 THEN
LEAVE simple_loop;
END IF;
END LOOP simple_loop;
END $$
To call that stored procedure use
CALL `ABC`()
The best alternative to typedef
that I've found in C# is using
. For example, I can control float precision via compiler flags with this code:
#if REAL_T_IS_DOUBLE
using real_t = System.Double;
#else
using real_t = System.Single;
#endif
Unfortunately, it requires that you place this at the top of every file where you use real_t
. There is currently no way to declare a global namespace type in C#.
Yes it is, there have to be boolean expresion after IF. Here you have a direct link. I hope it helps. GL!
The files/folder in your version control will not just delete themselves just because you added them to the .gitignore
. They are already in the repository and you have to remove them. You can just do that with this:
Remember to commit everything you've changed before you do this!
git rm -rf --cached .
git add .
This removes all files from the repository and adds them back (this time respecting the rules in your .gitignore
).
I would suggest this:
e.pageX - this.getBoundingClientRect().left
test.html
is will be helpful for how to use VLC WebAPI.

You can get vlc object from getVLC()
.
It works on IE 10 and Chrome.
function getVLC(name)
{
if (window.document[name])
{
return window.document[name];
}
if (navigator.appName.indexOf("Microsoft Internet")==-1)
{
if (document.embeds && document.embeds[name])
return document.embeds[name];
}
else // if (navigator.appName.indexOf("Microsoft Internet")!=-1)
{
return document.getElementById(name);

If you want to do this without VBA, you can use a combination of IF
, ISERROR
, and MATCH
.
So if all values are in column A, enter this formula in column B:
=IF(ISERROR(MATCH(12345,A:A,0)),"Not Found","Value found on row " & MATCH(12345,A:A,0))
This will look for the value "12345" (which can also be a cell reference). If the value isn't found, MATCH
returns "#N/A" and ISERROR
tries to catch that.
If you want to use VBA, the quickest way is to use a FOR loop:
Sub FindMatchingValue()
Dim i as Integer, intValueToFind as integer
intValueToFind = 12345
For i = 1 to 500 ' Revise the 500 to include all of your values
If Cells(i,1).Value = intValueToFind then
MsgBox("Found value on row " & i)
Exit Sub
End If
Next i
' This MsgBox will only show if the loop completes with no success
MsgBox("Value not found in the range!")
End Sub
You can use Worksheet Functions in VBA, but they're picky and sometimes throw nonsensical errors. The FOR
loop is pretty foolproof.
To UPLOAD a single file, you will need to create a bash script. Something like the following should work on OS X if you have sshpass
installed.
Usage:
sftpx <password> <user@hostname> <localfile> <remotefile>
Put this script somewhere in your path and call it sftpx
:
#!/bin/bash
export RND=`cat /dev/urandom | env LC_CTYPE=C tr -cd 'a-f0-9' | head -c 32`
export TMPDIR=/tmp/$RND
export FILENAME=$(basename "$4")
export DSTDIR=$(dirname "$4")
mkdir $TMPDIR
cp "$3" $TMPDIR/$FILENAME
export SSHPASS=$1
sshpass -e sftp -oBatchMode=no -b - $2 << !
lcd $TMPDIR
cd $DSTDIR
put $FILENAME
bye
!
rm $TMPDIR/$FILENAME
rmdir $TMPDIR
We are using Centos7, spring boot application with systemd. I was running java as below. and setting StandardOutput to file was not working for me.

Most problems are naturally expressed by recursion such as Fibonacci, Merge sorting and quick sorting. In this respect, the code is written for humans, not machines.
Iterative solutions often rely on varying temporary variables which makes the code hard to read. This can be avoided with recursion.
Recursion is not stack friendly. Stack can overflow when the recursion is not well designed or tail optimization is not supported.
Just in case commands in previous answers doesn't work,
Try this:
dat.dropna(subset=['x'], inplace = True)
DROP that table and again run Spring Project. That might help. Sometime you are overriding foreignKey.
You can run a shell in a running docker container using a command like:
docker exec -it --user root <container id> /bin/bash
Your code is correct. I tested:
r = requests.get("http://www.google.com")
print(r.content)
And it returned plenty of content. Check the url, try "http://www.google.com". Cheers!
Here is an actual working version of the above async foreach variants with sequential processing:
public static async Task ForEachAsync<T>(this List<T> enumerable, Action<T> action)
{
foreach (var item in enumerable)
await Task.Run(() => { action(item); }).ConfigureAwait(false);
}
Here is the implementation:
public async void SequentialAsync()
{
var list = new List<Action>();
Action action1 = () => {
//do stuff 1
};
Action action2 = () => {
//do stuff 2
};
list.Add(action1);
list.Add(action2);
await list.ForEachAsync();
}
What's the key difference? .ConfigureAwait(false);
which keeps the context of main thread while async sequential processing of each task.
You can delete any QuerySet you'd like. For example, to delete all blog posts with some Post model
Post.objects.all().delete()
and to delete any Post with a future publication date
Post.objects.filter(pub_date__gt=datetime.now()).delete()
You do, however, need to come up with a way to narrow down your QuerySet. If you just want a view to delete a particular object, look into the delete generic view.
EDIT:
Sorry for the misunderstanding. I think the answer is somewhere between. To implement your own, combine ModelForm
s and generic views. Otherwise, look into 3rd party apps that provide similar functionality. In a related question, the recommendation was django-filter.
You can use the -v
or --version
flag. For example
gem install bitclock -v '< 0.0.2'
To specify upper AND lower version boundaries you can specify the --version
flag twice
gem install bitclock -v '>= 0.0.1' -v '< 0.0.2'
or use the syntax (for example)
gem install bitclock -v '>= 0.0.1, < 0.0.2'
The other way to do it is
gem install bitclock:'>= 0.0.1'
but with the last option it is not possible to specify upper and lower bounderies simultaneously.
[gem 3.0.3 and ruby 2.6.6]
You can create a Date
object, and call getTime
on it:
new Date(2010, 6, 26).getTime() / 1000
var num = 123456;_x000D_
var digits = num.toString().split('');_x000D_
var realDigits = digits.map(Number)_x000D_
console.log(realDigits);
_x000D_
Use quit()
in this context. break
expects to be inside a loop, and return
expects to be inside a function.
FYI, this is of little or no use to the OP but it may be of use to other readers (please do not downvote, I'm aware of this).
As a somewhat ridiculous but interesting exercise, wanted to see if I could use python functional programming to replace multiple chars. I'm pretty sure this does NOT beat just calling replace() twice. And if performance was an issue, you could easily beat this in rust, C, julia, perl, java, javascript and maybe even awk. It uses an external 'helpers' package called pytoolz, accelerated via cython (cytoolz, it's a pypi package).
from cytoolz.functoolz import compose
from cytoolz.itertoolz import chain,sliding_window
from itertools import starmap,imap,ifilter
from operator import itemgetter,contains
text='&hello#hi&yo&'
char_index_iter=compose(partial(imap, itemgetter(0)), partial(ifilter, compose(partial(contains, '#&'), itemgetter(1))), enumerate)
print '\\'.join(imap(text.__getitem__, starmap(slice, sliding_window(2, chain((0,), char_index_iter(text), (len(text),))))))
I'm not even going to explain this because no one would bother using this to accomplish multiple replace. Nevertheless, I felt somewhat accomplished in doing this and thought it might inspire other readers or win a code obfuscation contest.
All the existing answers only work from the sqlite command line, which isn't ideal if you'd like to build a reusable script. Python makes it easy to build a script that can be executed programatically.
import pandas as pd
import sqlite3
conn = sqlite3.connect('your_cool_database.sqlite')
df = pd.read_sql('SELECT * from orders', conn)
df.to_csv('orders.csv', index = False)
You can customize the query to only export part of the sqlite table to the CSV file.
You can also run a single command to export all sqlite tables to CSV files:
for table in c.execute("SELECT name FROM sqlite_master WHERE type='table';").fetchall():
t = table[0]
df = pd.read_sql('SELECT * from ' + t, conn)
df.to_csv(t + '_one_command.csv', index = False)

You are probably experiencing an issue with a firewall. The 'problem' is that the port you specify is not the only port used, it uses 1 or maybe even 2 more ports for RMI, and those are probably blocked by a firewall.
One of the extra ports will not be know up front if you use the default RMI configuration, so you have to open up a big range of ports - which might not amuse the server administrator.
There is a solution that does not require opening up a lot of ports however, I've gotten it to work using the combined source snippets and tips from
http://forums.sun.com/thread.jspa?threadID=5267091 - link doesn't work anymore

It's even possible to setup an ssh tunnel and still get it to work :-)
If you are willing to use an external library, I can't recommend bstrlib
enough. It takes a little extra setup, but is easier to use in the long run.
For example, split the string below, one first creates a bstring
with the bfromcstr()
call. (A bstring
is a wrapper around a char buffer).
Next, split the string on commas, saving the result in a struct bstrList
, which has fields qty
and an array entry
, which is an array of bstring
s.
bstrlib
has many other functions to operate on bstring
s
Easy as pie...
#include "bstrlib.h"
#include <stdio.h>
int main() {
int i;
char *tmp = "Hello,World,sak";
bstring bstr = bfromcstr(tmp);
struct bstrList *blist = bsplit(bstr, ',');
printf("num %d\n", blist->qty);
for(i=0;i<blist->qty;i++) {
printf("%d: %s\n", i, bstr2cstr(blist->entry[i], '_'));
}
}
Very simple steps:
You will see disable button over the extension, click to it then restart Visual Studio and that's it!
Your code is OK. Note though that if you return a pointer to an array, and that array goes out of scope, you should not use that pointer anymore. Example:
int* test (void)
{
int out[5];
return out;
}
The above will never work, because out
does not exist anymore when test()
returns. The returned pointer must not be used anymore. If you do use it, you will be reading/writing to memory you shouldn't.
In your original code, the arr
array goes out of scope when main()
returns. Obviously that's no problem, since returning from main()
also means that your program is terminating.
If you want something that will stick around and cannot go out of scope, you should allocate it with new
:
int* test (void)
{
int* out = new int[5];
return out;
}
The returned pointer will always be valid. Remember do delete it again when you're done with it though, using delete[]
:
int* array = test();
// ...
// Done with the array.
delete[] array;
Deleting it is the only way to reclaim the memory it uses.
You can use a DecimalFormat, or String.format("%.2f", a);
The greps can be chained. For example:
tail -f admin.log | grep -v "Nopaging the limit is" | grep -v "keyword to remove is"
That is a binary operator in hibernate you should use

Have a look at 14.10. Expressions
Spring has something called a AnnotatedTypeScanner
class.
This class internally uses
ClassPathScanningCandidateComponentProvider
This class has the code for actual scanning of the classpath resources. It does this by using the class metadata available at runtime.
One can simply extend this class or use the same class for scanning. Below is the constructor definition.
/**
* Creates a new {@link AnnotatedTypeScanner} for the given annotation types.
*
* @param considerInterfaces whether to consider interfaces as well.
* @param annotationTypes the annotations to scan for.
*/
public AnnotatedTypeScanner(boolean considerInterfaces, Class<? extends Annotation>... annotationTypes) {
this.annotationTypess = Arrays.asList(annotationTypes);
this.considerInterfaces = considerInterfaces;
}
I think you could do:
$('#google_translate_element').find('*').each(function(){
$(this).unbind('click');
});
but it would cause a lot of overhead
This is typical programming practice for defining variables that are member variables. So when you're using them later, you don't need to see where they're defined to know their scope. This is also great if you already know the scope and you're using something like intelliSense, you can start with m_
and a list of all your member variables are shown. Part of Hungarian notation, see the part about scope in the examples here.
You can use the Enum.TryParse method:
Age age;
if (Enum.TryParse<Age>("New_Born", out age))
{
// You now have the value in age
}
I had similar situation , where i had to wait till all child threads complete its execution then only i could get the status result for each of them .. hence i needed to wait till all child thread completed.
below is my code where i did multi-threading using
public static void main(String[] args) {
List<RunnerPojo> testList = ExcelObject.getTestStepsList();//.parallelStream().collect(Collectors.toList());
int threadCount = ConfigFileReader.getInstance().readConfig().getParallelThreadCount();
System.out.println("Thread count is : ========= " + threadCount); // 5
ExecutorService threadExecutor = new DriverScript().threadExecutor(testList, threadCount);
boolean isProcessCompleted = waitUntilCondition(() -> threadExecutor.isTerminated()); // Here i used waitUntil condition
if (isProcessCompleted) {
testList.forEach(x -> {
System.out.println("Test Name: " + x.getTestCaseId());
System.out.println("Test Status : " + x.getStatus());
System.out.println("======= Test Steps ===== ");
x.getTestStepsList().forEach(y -> {
System.out.println("Step Name: " + y.getDescription());
System.out.println("Test caseId : " + y.getTestCaseId());
System.out.println("Step Status: " + y.getResult());
System.out.println("\n ============ ==========");
});
});
}
Below method is for distribution of list with parallel proccessing
// This method will split my list and run in a parallel process with mutliple threads
private ExecutorService threadExecutor(List<RunnerPojo> testList, int threadSize) {
ExecutorService exec = Executors.newFixedThreadPool(threadSize);
testList.forEach(tests -> {
exec.submit(() -> {
driverScript(tests);
});
});
exec.shutdown();
return exec;
}
This is my wait until method: here you can wait till your condition satisfies within do while loop . in my case i waited for some max timeout .
this will keep checking until your threadExecutor.isTerminated()
is true
with polling period of 5 sec.
static boolean waitUntilCondition(Supplier<Boolean> function) {
Double timer = 0.0;
Double maxTimeOut = 20.0;
boolean isFound;
do {
isFound = function.get();
if (isFound) {
break;
} else {
try {
Thread.sleep(5000); // Sleeping for 5 sec (main thread will sleep for 5 sec)
} catch (InterruptedException e) {
e.printStackTrace();
}
timer++;
System.out.println("Waiting for condition to be true .. waited .." + timer * 5 + " sec.");
}
} while (timer < maxTimeOut + 1.0);
return isFound;
}
Use fabs()
(in math.h) to get absolute-value for double
:
double d1 = fabs(-3.8951);
If you are looking to reduce the size using coding itself, you can follow this code in php.
<?php
function compress($source, $destination, $quality) {
$info = getimagesize($source);
if ($info['mime'] == 'image/jpeg')
$image = imagecreatefromjpeg($source);
elseif ($info['mime'] == 'image/gif')
$image = imagecreatefromgif($source);
elseif ($info['mime'] == 'image/png')
$image = imagecreatefrompng($source);
imagejpeg($image, $destination, $quality);
return $destination;
}
$source_img = 'source.jpg';
$destination_img = 'destination .jpg';
$d = compress($source_img, $destination_img, 90);
?>
$d = compress($source_img, $destination_img, 90);
This is just a php function that passes the source image ( i.e., $source_img
), destination image ( $destination_img
) and quality for the image that will take to compress ( i.e., 90 ).
$info = getimagesize($source);
The getimagesize()
function is used to find the size of any given image file and return the dimensions along with the file type.
I had the same issue with a VM running CentOS7 and Oracle 11GR2 accesible from Windows 7, the solution were weird, at my local machine the tnsnames pointing to the DB had a space before the service name, I just deleted the space and then I was able to connect.
A quick example.
Wrong tnsnames.
[this is a empty space]XE = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = XE) ) )
EXTPROC_CONNECTION_DATA = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE)) ) (CONNECT_DATA = (SID = PLSExtProc) (PRESENTATION = RO) ) )
Right tnsnames.
XE = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = XE) ) )
EXTPROC_CONNECTION_DATA = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE)) ) (CONNECT_DATA = (SID = PLSExtProc) (PRESENTATION = RO) ) )
Add reference to Microsoft.VisualBasic
and use this into your C# code:
string input = Microsoft.VisualBasic.Interaction.InputBox("Prompt",
"Title",
"Default",
0,
0);
To add the refernce: right-click on the References in your Project Explorer window then on Add Reference, and check VisualBasic from that list.
$gcc -o program program.c -l <library_to_resolve_program.c's_unresolved_symbols>
A good description of why the placement of -l dl matters
But there's also a pretty succinct explanation in the docs From $man gcc
-llibrary -l library Search the library named library when linking. (The second alternative with the library as a separate argument is only for POSIX compliance and is not recommended.)
It makes a difference where in the command you write this option; the
linker searches and processes libraries and object files in the order
they are specified. Thus, foo.o -lz bar.o searches library z after
file foo.o but before bar.o. If bar.o refers to functions in z,
those functions may not be loaded.
Just subtract:
var a = new Date();
alert("Wait a few seconds, then click OK");
var b = new Date();
var difference = (b - a) / 1000;
alert("You waited: " + difference + " seconds");
int i = (int)char.GetNumericValue(c);
Yet another option:
int i = c & 0x0f;
This should accomplish this as well.
In Symfony 4, you can use the ParameterBagInterface
:
use Symfony\Component\DependencyInjection\ParameterBag\ParameterBagInterface;
class MessageGenerator
{
private $params;
public function __construct(ParameterBagInterface $params)
{
$this->params = $params;
}
public function someMethod()
{
$parameterValue = $this->params->get('parameter_name');
// ...
}
}
and in app/config/services.yaml
:
parameters:
locale: 'en'
dir: '%kernel.project_dir%'
It works for me in both controller and form classes. More details can be found in the Symfony blog.
Another way to write it shortly
bePlanVar = !!((bePlanVar == false));
// is equivalent to
bePlanVar = (bePlanVar == false) ? true : false;
// and
if (bePlanVar == false) {
bePlanVar = true;
} else {
bePlanVar = false;
}
Here's yet another answer:
public static int AgeInYears(DateTime birthday, DateTime today)
{
return ((today.Year - birthday.Year) * 372 + (today.Month - birthday.Month) * 31 + (today.Day - birthday.Day)) / 372;
}
This has been extensively unit-tested. It does look a bit "magic". The number 372 is the number of days there would be in a year if every month had 31 days.
The explanation of why it works (lifted from here) is:
Let's set
Yn = DateTime.Now.Year, Yb = birthday.Year, Mn = DateTime.Now.Month, Mb = birthday.Month, Dn = DateTime.Now.Day, Db = birthday.Day
age = Yn - Yb + (31*(Mn - Mb) + (Dn - Db)) / 372
We know that what we need is either
Yn-Yb
if the date has already been reached,Yn-Yb-1
if it has not.a) If
Mn<Mb
, we have-341 <= 31*(Mn-Mb) <= -31 and -30 <= Dn-Db <= 30
-371 <= 31*(Mn - Mb) + (Dn - Db) <= -1
With integer division
(31*(Mn - Mb) + (Dn - Db)) / 372 = -1
b) If
Mn=Mb
andDn<Db
, we have31*(Mn - Mb) = 0 and -30 <= Dn-Db <= -1
With integer division, again
(31*(Mn - Mb) + (Dn - Db)) / 372 = -1
c) If
Mn>Mb
, we have31 <= 31*(Mn-Mb) <= 341 and -30 <= Dn-Db <= 30
1 <= 31*(Mn - Mb) + (Dn - Db) <= 371
With integer division
(31*(Mn - Mb) + (Dn - Db)) / 372 = 0
d) If
Mn=Mb
andDn>Db
, we have31*(Mn - Mb) = 0 and 1 <= Dn-Db <= 3
0With integer division, again
(31*(Mn - Mb) + (Dn - Db)) / 372 = 0
e) If
Mn=Mb
andDn=Db
, we have31*(Mn - Mb) + Dn-Db = 0
and therefore
(31*(Mn - Mb) + (Dn - Db)) / 372 = 0
IntelliJ IDEA 2018.1.4 (Ultimate Edition) built on May 16, 2018
in this link i mentioned before on the comment, read this part :
A "fetch" join allows associations or collections of values to be initialized along with their parent objects using a single select. This is particularly useful in the case of a collection. It effectively overrides the outer join and lazy declarations of the mapping file for associations and collections.
this "JOIN FETCH" will have it's effect if you have (fetch = FetchType.LAZY) property for a collection inside entity(example bellow).
And it is only effect the method of "when the query should happen". And you must also know this:
hibernate have two orthogonal notions : when is the association fetched and how is it fetched. It is important that you do not confuse them. We use fetch to tune performance. We can use lazy to define a contract for what data is always available in any detached instance of a particular class.
when is the association fetched --> your "FETCH" type
how is it fetched --> Join/select/Subselect/Batch
In your case, FETCH will only have it's effect if you have department as a set inside Employee, something like this in the entity:
@OneToMany(fetch = FetchType.LAZY)
private Set<Department> department;
when you use
FROM Employee emp
JOIN FETCH emp.department dep
you will get emp
and emp.dep
. when you didnt use fetch you can still get emp.dep
but hibernate will processing another select to the database to get that set of department.
so its just a matter of performance tuning, about you want to get all result(you need it or not) in a single query(eager fetching), or you want to query it latter when you need it(lazy fetching).
Use eager fetching when you need to get small data with one select(one big query). Or use lazy fetching to query what you need latter(many smaller query).
use fetch when :
no large unneeded collection/set inside that entity you about to get
communication from application server to database server too far and need long time
you may need that collection latter when you don't have the access to it(outside of the transactional method/class)
As of the 3.2 SDK you can access the view property of MPMoviePlayerController
, modify its frame and add it to your view hierarchy.
MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:url]];
player.view.frame = CGRectMake(184, 200, 400, 300);
[self.view addSubview:player.view];
[player play];
There's an example here: http://www.devx.com/wireless/Article/44642/1954
use it like this for mroe info read this topic
<a [routerLink]="['/about']">About this</a>
Use Timeout
$timeout(function () { console.log($state.current, 'this is working fine'); }, 100);
This may work for you:
select t1.*
from table t1
join (select t2.Chromosome, t2.Locus
from table2
group by t2.Chromosome, t2.Locus
having count(*) > 1) u on u.Chromosome = t1.Chromosome and u.Locus = t1.Locus

If your float is always expressed in decimal notation something like
>>> import re
>>> re.findall("\d+\.\d+", "Current Level: 13.4 db.")
['13.4']
may suffice.
A more robust version would be:
>>> re.findall(r"[-+]?\d*\.\d+|\d+", "Current Level: -13.2 db or 14.2 or 3")
['-13.2', '14.2', '3']
If you want to validate user input, you could alternatively also check for a float by stepping to it directly:
user_input = "Current Level: 1e100 db"
for token in user_input.split():
try:
# if this succeeds, you have your (first) float
print float(token), "is a float"
except ValueError:
print token, "is something else"
# => Would print ...
#
# Current is something else
# Level: is something else
# 1e+100 is a float
# db is something else
This Error can occur if the physical machine has run out of memory. In my case i was hosting a site on IIS trying to access the AD, but the server had run out of memory.
You can use window.open for this
window.open("page url",null,
"height=200,width=400,status=yes,toolbar=no,menubar=no,location=no");
have a look at this link.. window.open
You can only stringify the array and append it. Sends the array as an actual Array even if it has only one item.
const array = [ 1, 2 ];
let formData = new FormData();
formData.append("numbers", JSON.stringify(array));
Ideally you should use a transparent PNG with the circle in white and the background of the image transparent. Then you can set the background-color
of the .fb-icon
to blue on hover. So you're CSS would be:
fb-icon{
background:none;
}
fb-icon:hover{
background:#0000ff;
}
Additionally, if you don't want to use PNG's you can also use a sprite and alter the background position. A sprite is one large image with a collection of smaller images which can be used as a background image by changing the background position. So for eg, if your original circle image with the white background is 100px X 100px, you can increase the height of the image to 100px X 200px, so that the top half is the original image with the white background, while the lower half is the new image with the blue background. Then you set setup your CSS as:
fb-icon{
background:url('path/to/image/image.png') no-repeat 0 0;
}
fb-icon:hover{
background:url('path/to/image/image.png') no-repeat 0 -100px;
}
"Any CPU" means that when the program is started, the .NET Framework will figure out, based on the OS bitness, whether to run your program in 32 bits or 64 bits.
There is a difference between x86 and Any CPU: on a x64 system, your executable compiled for X86 will run as a 32-bit executable.
As far as your suspicions go, just go to the Visual Studio 2008 command line and run the following.
dumpbin YourProgram.exe /headers
It will tell you the bitness of your program, plus a whole lot more.
Another way of achieving it would be to temporary edit the gitignore file, add the file and then revert back the gitignore. A bit hacky i feel
Complete answer:
1. Is there a function available in SQL?
Yes, the SQL 92 spec, Oct 97, pg. 171, section 6.16 specifies this functions:
CURRENT_TIME Time of day at moment of evaluation
CURRENT_DATE Date at moment of evaluation
CURRENT_TIMESTAMP Date & Time at moment of evaluation
2. It is implementation depended so each database has its own function for this?
Each database has its own implementations, but they have to implement the three function above if they comply with the SQL 92 specification (but depends on the version of the spec)
3. What is the function available in MySQL?
NOW() returns 2009-08-05 15:13:00
CURDATE() returns 2009-08-05
CURTIME() returns 15:13:00
Here is an implementation without using jQuery at all -
http://thezillion.wordpress.com/2012/09/27/javascript-draggable-2-no-jquery
Embed the JS file (http://zillionhost.xtreemhost.com/tzdragg/tzdragg.js) in your HTML code, and put the following code -
<script>
win.onload = function(){
tzdragg.drag('elem1, elem2, ..... elemn');
// ^ IDs of the draggable elements separated by a comma.
}
</script>
And the code is also easy to learn.

Yes, StringBuilder
gives better performance while performing repeated operation over a string. It is because all the changes are made to a single instance so it can save a lot of time instead of creating a new instance like String

I will do something like this:
function findLongestWord(str) {
var array = str.split(" ");
var maxLength=array[0].length;
for(var i=0; i < array.length; i++ ) {
if(array[i].length > maxLength) maxLength = array[i].length}
return maxLength;}
findLongestWord("What if we try a super-long word such as otorhinolaryngology");
A functional way can be achieved using filter
and lambda
operator.
list1 = [1,2,3,4,5,6]
list2 = [2,4,6,9,10]
>>> list(filter(lambda x:x in list1, list2))
[2, 4, 6]
Edit: It filters out x that exists in both list1 and list, set difference can also be achieved using:
>>> list(filter(lambda x:x not in list1, list2))
[9,10]
Edit2: python3 filter
returns a filter object, encapsulating it with list
returns the output list.
I found a solution for this problem. The issue I described in my question occured basically due to the incompatibility of the Microsoft.Jet.OLEDB.4.0 driver in 64 bit OS.
So if we are using Microsoft.Jet.OLEDB.4.0 driver in a 64 bit server, we have to force our application to build in in 32 bit mode (This is the answer I found when I did an extensive search for this known issue) and that causes other part of my code to break.
Fortunately, now Microsoft has released a 64 bit compatible 2010 Office System Driver which can be used as replacement for the traditional Microsoft.Jet.OLEDB.4.0 driver. It works both in 32 bit as well as 64 bit servers. I have used it for Excel file manipulation and it worked fine for me in both the environments. But this driver is in BETA.
You can download this driver from Microsoft Access Database Engine 2010 Redistributable
For me I had a special characters in my password field, and I put it like $mail->Password = " por$ch3" which work for gmail smpt server but not for other; so I just changed double quotes to single quotes and it works for me. $mail->Password = ' por$ch3';

I was over-complicating myself. After taking a long break and coming back, the desired output could be accomplished by this simple query:
SELECT Sandwiches.[Sandwich Type], Sandwich.Bread, Count(Sandwiches.[SandwichID]) AS [Total Sandwiches]
FROM Sandwiches
GROUP BY Sandwiches.[Sandwiches Type], Sandwiches.Bread;
Thanks for answering, it helped my train of thought.

I am using php 7.3.8 on a manjaro and I was working with Persian content. This solved my problem:
$html = 'hi</b><p>????<div>?????9 ?';
$doc = new DOMDocument('1.0', 'UTF-8');
$doc->loadHTML(mb_convert_encoding($html, 'HTML-ENTITIES', 'UTF-8'));
print $doc->saveHTML($doc->documentElement) . PHP_EOL . PHP_EOL;
You can use the Class XmlAttribute.
Eg:
XmlAttribute attr = xmlDoc.CreateAttribute("userName");
attr.Value = "Tushar";
node.Attributes.Append(attr);
This is the command worked for me.
cat your_dump.sql | sudo docker exec -i {docker-postgres-container} psql -U {user} -d {database_name}
for example
cat table_backup.sql | docker exec -i 03b366004090 psql -U postgres -d postgres

Using the code example below will return to you the bitmap :
BitmapFactory.decodeStream(getContentResolver().openInputStream(Uri.parse("content://com.whatsapp.provider.media/item/128752")))
After that you all know what you have to do.
this way worked better for me:
echo y | keytool -storepasswd -storepass 123456 -keystore /tmp/IT-Root-CA.keystore -import -alias IT-Root-CA -file /etc/pki/ca-trust/source/anchors/IT-Root-CA.crt

You can create a camera intent and call it as startActivityForResult(intent).
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
// start the image capture Intent
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
If one want to keep getting updated processes (on the example, 2 seconds) on a shell session without having to manually interact with it use:
watch -n 2 'mysql -h 127.0.0.1 -P 3306 -u some_user -psome_pass some_database -e "show full processlist;"'
The only bad thing about the show [full] processlist
is that you can't filter the output result. On the other hand, issuing the SELECT * FROM INFORMATION_SCHEMA.PROCESSLIST
open possibilities to remove from the output anything you don't want to see:
SELECT * from INFORMATION_SCHEMA.PROCESSLIST
WHERE DB = 'somedatabase'
AND COMMAND <> 'Sleep'
AND HOST NOT LIKE '10.164.25.133%' \G
I just had to uncomment the line in jboss-eap-5.0\jboss-as\server\default\conf\props\jmx-console-users.properties

Thats it. Restart Jboss and I was about to get in to JBOSS JMX. Magically this even fixed the error that I used to get while shutting down Jboss from Eclipse.

I know this is an older question, but I wanted to post an answer for users with the same question:
curl -H 'Cache-Control: no-cache' http://www.example.com
This curl command servers in its header request to return non-cached data from the web server.
In this part of your SP:
IF @DateFirst <> '' and @DateLast <> ''
set @FinalSQL = @FinalSQL
+ ' or convert (Date,DateLog) >= ''' + @DateFirst
+ ' and convert (Date,DateLog) <=''' + @DateLast
you are trying to concatenate strings and datetimes.
As the datetime
type has higher priority than varchar
/nvarchar
, the +
operator, when it happens between a string and a datetime, is interpreted as addition, not as concatenation, and the engine then tries to convert your string parts (' or convert (Date,DateLog) >= '''
and others) to datetime or numeric values. And fails.
That doesn't happen if you omit the last two parameters when invoking the procedure, because the condition evaluates to false and the offending statement isn't executed.
To amend the situation, you need to add explicit casting of your datetime variables to strings:
set @FinalSQL = @FinalSQL
+ ' or convert (Date,DateLog) >= ''' + convert(date, @DateFirst)
+ ' and convert (Date,DateLog) <=''' + convert(date, @DateLast)
You'll also need to add closing single quotes:
set @FinalSQL = @FinalSQL
+ ' or convert (Date,DateLog) >= ''' + convert(date, @DateFirst) + ''''
+ ' and convert (Date,DateLog) <=''' + convert(date, @DateLast) + ''''
I would give a badly written query and ask them how they would go about performance tuning it.
I would ask about set theory. If you don't understand operating in sets, you can't effectively query a relational database.
I would give them some cursor examples and ask how they would rewrite them to make them set-based.
If the job involved imports and exports I would ask questions about SSIS (or other tools involved in doing this used by other datbases). If it involved writing reports, I would want to know that they understand aggregates and grouping (As well as Crystal Reports or SSRS or whatever ereporting tool you use).
I would ask the difference in results between these three queries:
select a.field1
, a.field2
, b.field3
from table1 a
join table2 b
on a.id = b.id
where a.field5 = 'test'
and b.field3 = 1
select a.field1
, a.field2
, b.field3
from table1 a
left join table2 b
on a.id = b.id
where a.field5 = 'test'
and b.field3 = 1
select a.field1
, a.field2
, b.field3
from table1 a
left join table2 b
on a.id = b.id and b.field3 = 1
where a.field5 = 'test'
Another option is to use the getBoundingClientRect function. Please note that getBoundingClientRect will return an empty rect if the element's display is 'none'.
var elem = document.getElementById("myDiv");
if(elem) {
var rect = elem.getBoundingClientRect();
console.log(rect.width);
}
Javascript has a random()
available. Take a look at Math.random().
Simply use this in your adapter, Where MainActivity is your AppCompactActivity. Call it from anywhere.

Assuming a modern release, find -newermt
is powerful:
find -newermt '10 minutes ago' ## other units work too, see `Date input formats`
or, if you want to specify a time_t
(seconds since epoch):
find -newermt @1568670245
For reference, -newermt
is not directly listed in the man page for find. Instead, it is shown as -newerXY
, where XY
are placeholders for mt
. Other replacements are legal, but not applicable for this solution.
From man find -newerXY
:
Time specifications are interpreted as for the argument to the -d option of GNU date.
So the following are equivalent to the initial example:
find -newermt "$(date '+%Y-%m-%d %H:%M:%S' -d '10 minutes ago')" ## long form using 'date'
find -newermt "@$(date +%s -d '10 minutes ago')" ## short form using 'date' -- notice '@'
The date -d
(and find -newermt
) arguments are quite flexible, but the documentation is obscure. Here's one source that seems to be on point: Date input formats
From what I can see there are helper methods inside the ControllerBase
class. Just use the StatusCode
method:
[HttpPost]
public IActionResult Post([FromBody] string something)
{
//...
try
{
DoSomething();
}
catch(Exception e)
{
LogException(e);
return StatusCode(500);
}
}
You may also use the StatusCode(int statusCode, object value)
overload which also negotiates the content.
Depending on distribution, using "cron reload" might do nothing. To paste a snippet out of init.d/cron (debian squeeze):
reload|force-reload) log_daemon_msg "Reloading configuration files for periodic command scheduler" "cron"
# cron reloads automatically
log_end_msg 0
;;
Some developer/maintainer relied on it reloading, but doesn't, and in this case there's not a way to force reload. I'm generating my crontab files as part of a deploy, and unless somehow the length of the file changes, the changes are not reloaded.
Old Question, but for angular 6
, this needs to be done when you are using HttpClient
I am exposing token data publicly here but it would be good if accessed via read-only properties.
import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { Observable, of } from 'rxjs';
import { delay, tap } from 'rxjs/operators';
import { Router } from '@angular/router';
@Injectable()
export class AuthService {
isLoggedIn: boolean = false;
url = "token";
tokenData = {};
username = "";
AccessToken = "";
constructor(private http: HttpClient, private router: Router) { }
login(username: string, password: string): Observable<object> {
let model = "username=" + username + "&password=" + password + "&grant_type=" + "password";
return this.http.post(this.url, model).pipe(
tap(
data => {
console.log('Log In succesful')
//console.log(response);
this.isLoggedIn = true;
this.tokenData = data;
this.username = data["username"];
this.AccessToken = data["access_token"];
console.log(this.tokenData);
return true;
},
error => {
console.log(error);
return false;
}
)
);
}
}
In PHP >= 7.1 this is possible. See this answer.
If you can modify the exceptions, use this answer.
If you can't, you could try catching all with Exception
and then check which exception was thrown with instanceof
.
try
{
/* something */
}
catch( Exception $e )
{
if ($e instanceof AError OR $e instanceof BError) {
// It's either an A or B exception.
} else {
// Keep throwing it.
throw $e;
}
}
But it would probably be better to use multiple catch blocks as described in aforementioned answer.
try
{
/* something */
}
catch( AError $e )
{
handler1( $e );
}
catch ( BError $b )
{
handler2( $e );
}
You use the modulo operator:
while(score)
{
printf("%d\n", score % 10);
score /= 10;
}
Note that this will give you the digits in reverse order (i.e. least significant digit first). If you want the most significant digit first, you'll have to store the digits in an array, then read them out in reverse order.
I had to go look for ojdbc compatible with version on oracle that was installed this fixed my problem, my bad was thinking one ojdbc would work for all
This is not the way to do it. You should use delegates.
I'll assume we have two view controllers, ViewController1 and ViewController2, and this check thing is in the first one and when its state changes, you want to do something in ViewController2. To achieve that in the proper way, you should do the below:
Add a new file to your project (Objective-C Protocol) menu File ? New. Now name it ViewController1Delegate or whatever you want and write these between the @interface and @end directives:
@optional
- (void)checkStateDidChange:(BOOL)checked;
Now go to ViewController2.h and add:
#import "ViewController1Delegate.h"
Then change its definition to:
@interface ViewController2: UIViewController<ViewController1Delegate>
Now go to ViewController2.m and inside the implementation add:
- (void)checkStateDidChange:(BOOL)checked {
if (checked) {
// Do whatever you want here
NSLog(@"Checked");
}
else {
// Also do whatever you want here
NSLog(@"Not checked");
}
}
Now go to ViewController1.h and add the following property:
@property (weak, nonatomic) id<ViewController1Delegate> delegate;
Now if you are creating ViewController1 inside ViewController2 after some event, then you should do it this way using NIB files:
ViewController1* controller = [[NSBundle mainBundle] loadNibNamed:@"ViewController1" owner:self options:nil][0];
controller.delegate = self;
[self presentViewController:controller animated:YES completion:nil];
Now you are all set. Whenever you detect the event of check changed in ViewController1, all you have to do is the below:
[delegate checkStateDidChange:checked]; // You pass here YES or NO based on the check state of your control
Look in the \application\config\config.php
file, there is a variable named index_page
It should look like this
$config['index_page'] = "index.php";
change it to
$config['index_page'] = "";
Then as mentioned you also need to add a rewrite rule to the .htaccess
file like this:
RewriteEngine on
RewriteCond $1 !^(index\\.php|resources|robots\\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]
It work for me, hope you too.
timespec_get
from C11
Returns up to nanoseconds, rounded to the resolution of the implementation.
Looks like an ANSI ripoff from POSIX' clock_gettime
.
Example: a printf
is done every 100ms on Ubuntu 15.10:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
static long get_nanos(void) {
struct timespec ts;
timespec_get(&ts, TIME_UTC);
return (long)ts.tv_sec * 1000000000L + ts.tv_nsec;
}
int main(void) {
long nanos;
long last_nanos;
long start;
nanos = get_nanos();
last_nanos = nanos;
start = nanos;
while (1) {
nanos = get_nanos();
if (nanos - last_nanos > 100000000L) {
printf("current nanos: %ld\n", nanos - start);
last_nanos = nanos;
}
}
return EXIT_SUCCESS;
}
The C11 N1570 standard draft 7.27.2.5 "The timespec_get function says":
If base is TIME_UTC, the tv_sec member is set to the number of seconds since an implementation defined epoch, truncated to a whole value and the tv_nsec member is set to the integral number of nanoseconds, rounded to the resolution of the system clock. (321)
321) Although a struct timespec object describes times with nanosecond resolution, the available resolution is system dependent and may even be greater than 1 second.
C++11 also got std::chrono::high_resolution_clock
: C++ Cross-Platform High-Resolution Timer
glibc 2.21 implementation
Can be found under sysdeps/posix/timespec_get.c
as:
int
timespec_get (struct timespec *ts, int base)
{
switch (base)
{
case TIME_UTC:
if (__clock_gettime (CLOCK_REALTIME, ts) < 0)
return 0;
break;
default:
return 0;
}
return base;
}
so clearly:
only TIME_UTC
is currently supported
it forwards to __clock_gettime (CLOCK_REALTIME, ts)
, which is a POSIX API: http://pubs.opengroup.org/onlinepubs/9699919799/functions/clock_getres.html
Linux x86-64 has a clock_gettime
system call.
Note that this is not a fail-proof micro-benchmarking method because:
man clock_gettime
says that this measure may have discontinuities if you change some system time setting while your program runs. This should be a rare event of course, and you might be able to ignore it.
this measures wall time, so if the scheduler decides to forget about your task, it will appear to run for longer.
For those reasons getrusage()
might be a better better POSIX benchmarking tool, despite it's lower microsecond maximum precision.
More information at: Measure time in Linux - time vs clock vs getrusage vs clock_gettime vs gettimeofday vs timespec_get?
This is an example of how I use this kind of thing:
HTML :
<input type="checkbox" id="ThisIsTheId" value="X" onchange="ThisIsTheFunction(this.id,this.checked)">
JAVASCRIPT :
function ThisIsTheFunction(temp,temp2) {
if(temp2 == true) {
document.getElementById(temp).style.visibility = "visible";
} else {
document.getElementById(temp).style.visibility = "hidden";
}
}
For numerical data you have the solution. But it is categorical data, you said. Then life gets a bit more complicated...
Well, first : The amount of association between two categorical variables is not measured with a Spearman rank correlation, but with a Chi-square test for example. Which is logic actually. Ranking means there is some order in your data. Now tell me which is larger, yellow or red? I know, sometimes R does perform a spearman rank correlation on categorical data. If I code yellow 1 and red 2, R would consider red larger than yellow.
So, forget about Spearman for categorical data. I'll demonstrate the chisq-test and how to choose columns using combn(). But you would benefit from a bit more time with Agresti's book : http://www.amazon.com/Categorical-Analysis-Wiley-Probability-Statistics/dp/0471360937
set.seed(1234)
X <- rep(c("A","B"),20)
Y <- sample(c("C","D"),40,replace=T)
table(X,Y)
chisq.test(table(X,Y),correct=F)
# I don't use Yates continuity correction
#Let's make a matrix with tons of columns
Data <- as.data.frame(
matrix(
sample(letters[1:3],2000,replace=T),
ncol=25
)
)
# You want to select which columns to use
columns <- c(3,7,11,24)
vars <- names(Data)[columns]
# say you need to know which ones are associated with each other.
out <- apply( combn(columns,2),2,function(x){
chisq.test(table(Data[,x[1]],Data[,x[2]]),correct=F)$p.value
})
out <- cbind(as.data.frame(t(combn(vars,2))),out)
Then you should get :
> out
V1 V2 out
1 V3 V7 0.8116733
2 V3 V11 0.1096903
3 V3 V24 0.1653670
4 V7 V11 0.3629871
5 V7 V24 0.4947797
6 V11 V24 0.7259321
Where V1 and V2 indicate between which variables it goes, and "out" gives the p-value for association. Here all variables are independent. Which you would expect, as I created the data at random.

You can create a StreamReader
around the stream, then call StreamReader.ReadToEnd()
.
StreamReader responseReader = new StreamReader(request.GetResponse().GetResponseStream());
var responseData = responseReader.ReadToEnd();
Dates are always a nightmare. Answering your old question, perhaps this is the most elegant way:
eval(("new " + "/Date(1455418800000)/").replace(/\//g,""))
With eval we convert our string to javascript code. Then we remove the "/", into the replace function is a regular expression. As we start with new then our sentences will excecute this:
new Date(1455418800000)
Now, one thing I started using long time ago, is long values that are represented in ticks... why? well, localization and stop thinking in how is date configured in every server or every client. In fact, I use it too in databases.
Perhaps is quite late for this answer, but can help anybody arround here.
You are printing the enum object. Use the .value
attribute if you wanted just to print that:
print(D.x.value)
See the Programmatic access to enumeration members and their attributes section:
If you have an enum member and need its name or value:
>>> >>> member = Color.red >>> member.name 'red' >>> member.value 1
You could add a __str__
method to your enum, if all you wanted was to provide a custom string representation:
class D(Enum):
def __str__(self):
return str(self.value)
x = 1
y = 2
Demo:
>>> from enum import Enum
>>> class D(Enum):
... def __str__(self):
... return str(self.value)
... x = 1
... y = 2
...
>>> D.x
<D.x: 1>
>>> print(D.x)
1
With Bootstrap 4 I use
.tooltip-inner {
margin-left: 50%;
max-width: 50%;

min-width: 300px;
}
You can do it.
BUT you cannot use @color references for colors (..lame), otherwise it will work only for L+

I like to keep is simple when possible. I needed to group by International, filter on all the columns, display the count for each group and hide the group if no items existed.
Plus I did not want to add a custom filter just for something simple like this.

Python is only a language, to get GET and POST data, you need a web framework or toolkit written in Python. Django is one, as Charlie points out, the cgi and urllib standard modules are others. Also available are Turbogears, Pylons, CherryPy, web.py, mod_python, fastcgi, etc, etc.
In Django, your view functions receive a request argument which has request.GET and request.POST. Other frameworks will do it differently.
You can't move the mouse pointer using javascript, and thus for obvious security reasons. The best way to achieve this effect would be to actually place the control under the mouse pointer.
Python string comparison is lexicographic:
From Python Docs: http://docs.python.org/reference/expressions.html
Strings are compared lexicographically using the numeric equivalents (the result of the built-in function ord()) of their characters. Unicode and 8-bit strings are fully interoperable in this behavior.
Hence in your example, 'abc' < 'bac'
, 'a' comes before (less-than) 'b' numerically (in ASCII and Unicode representations), so the comparison ends right there.
local_action
runs the command on the local server, not on the servers you specify in hosts
parameter.
Change your "Execute the script" task to
- name: Execute the script
command: sh /home/test_user/test.sh
and it should do it.
You don't need to repeat sudo in the command line because you have defined it already in the playbook.
According to Ansible Intro to Playbooks user
parameter was renamed to remote_user
in Ansible 1.4 so you should change it, too
remote_user: test_user
So, the playbook will become:
---
- name: Transfer and execute a script.
hosts: server
remote_user: test_user
sudo: yes
tasks:
- name: Transfer the script
copy: src=test.sh dest=/home/test_user mode=0777
- name: Execute the script
command: sh /home/test_user/test.sh
PyParsing does a great job. The PyParsing wiki was killed so here is another location where there are examples of the use of PyParsing (example link). One reason for investing a little time with pyparsing is that he has also written a very brief very well organized O'Reilly Short Cut manual that is also inexpensive.
Having said that, I use BeautifulSoup a lot and it is not that hard to deal with the entities issues, you can convert them before you run BeautifulSoup.
Goodluck
In the Divi Theme Documentation, it says that the theme comes with access to 'ePanel' which also has an 'Integration' section.
You should be able to add this code:
<script>
$( ".et-pb-icon" ).click(function() {
$( this ).toggleClass( "active" );
});
</script>
into the the box that says 'Add code to the head of your blog' under the 'Integration' tab, which should get the jQuery working.
Then, you should be able to style your class to what ever you need.
use ng-intl-tel-input to validate mobile numbers for all countries. you can set default country also. on npm: https://www.npmjs.com/package/ng-intl-tel-input

I found the example RichardTheKiwi quite informative.
Just to offer another approach if you're looking for something like IF EXISTS (SELECT 1 ..) THEN ...
-- what I might write in MSSQL
IF EXISTS (SELECT 1 FROM Table WHERE FieldValue='')
BEGIN
SELECT TableID FROM Table WHERE FieldValue=''
END
ELSE
BEGIN
INSERT INTO TABLE(FieldValue) VALUES('')
SELECT SCOPE_IDENTITY() AS TableID
END
-- rewritten for MySQL
IF (SELECT 1 = 1 FROM Table WHERE FieldValue='') THEN
BEGIN
SELECT TableID FROM Table WHERE FieldValue='';
END;
ELSE
BEGIN
INSERT INTO Table (FieldValue) VALUES('');
SELECT LAST_INSERT_ID() AS TableID;
END;
END IF;
Ok, this is an old thread but.
I had a same issue, my problem was I used json.load
instead of json.loads
This way, json has no problem with loading any kind of dictionary.
json.load - Deserialize fp (a .read()-supporting text file or binary file containing a JSON document) to a Python object using this conversion table.
json.loads - Deserialize s (a str, bytes or bytearray instance containing a JSON document) to a Python object using this conversion table.
Currently there is no direct Instagram API to get user id from user name. You need to call the GET /users/search API and then iterate the results and check if the username
field value is equal to your username or not, then you grab the id
.
A new way to do this has been available for some time now on modern browsers.
background-blend-mode allows you to get some interesting effects, and one of them is grayscale conversion
The value luminosity , set on a white background, allows it. (hover to see it in gray)
.test {_x000D_
width: 300px;_x000D_
height: 200px;_x000D_
background: url("http://placekitten.com/1000/750"), white; _x000D_
background-size: cover;_x000D_
}_x000D_
_x000D_
.test:hover {_x000D_
background-blend-mode: luminosity;_x000D_
}
_x000D_
<div class="test"></div>
_x000D_
The luminosity is taken from the image, the color is taken from the background. Since it is always white, there is no color.
But it allows much more.
You can animate the effect setting 3 layers. The first one will be the image, and the second will be a white-black gradient. If you apply a multiply blend mode on this, you will get a white result as before on the white part, but the original image on the black part (multiply by white gives white, multiplying by black has no effect.)
On the white part of the gradient, you get the same effect as before. On the black part of the gradient, you are blending the image over itself, and the result is the unmodified image.
Now, all that is needed is to move the gradient to get this effect dynamic: (hover to see it in color)
div {_x000D_
width: 600px;_x000D_
height: 400px;_x000D_
}_x000D_
_x000D_
.test {_x000D_
background: url("http://placekitten.com/1000/750"), _x000D_
linear-gradient(0deg, white 33%, black 66%), url("http://placekitten.com/1000/750"); _x000D_
background-position: 0px 0px, 0px 0%, 0px 0px;_x000D_
background-size: cover, 100% 300%, cover;_x000D_
background-blend-mode: luminosity, multiply;_x000D_
transition: all 2s;_x000D_
}_x000D_
_x000D_
.test:hover {_x000D_
background-position: 0px 0px, 0px 66%, 0px 0px;_x000D_
}
_x000D_
<div class="test"></div>
_x000D_
First, select the portion of the text containing the bits you want to change.
On Windows (sorry) it's Ctrl + H or Find > Replace...
This opens up the Find/Replace boxes at the bottom of the file. Enter your details then click Replace All
(or Ctrl + Alt + Enter)
while using Header array
String auth = Base64.getEncoder().encodeToString(("test1:test1").getBytes());
Header[] headers = {
new BasicHeader(HTTP.CONTENT_TYPE, ContentType.APPLICATION_JSON.toString()),
new BasicHeader("Authorization", "Basic " +auth)
};
Its a good to remember that config files can be split across secondary files to make config changes easier on different servers (dev/demo/production etc), without having to recompile code/app etc. For example we use them to allow onsite engineers to make endpoint changes without actually touching the 'real' files.
First step is to move the bindings section out of the WPF App.Config into it's own separate file.
The behaviours section is set to allow both http and https (doesn't seem to have an affect on the app if both are allowed)
<serviceMetadata httpsGetEnabled="true" httpGetEnabled="true" />
And we move the bindings section out to its own file;
<bindings configSource="Bindings.config" />
In the bindings.config file we switch the security based on protocol
<!-- None = http:// -->
<!-- Transport = https:// -->
<security mode="None" >
Now the on site engineers only need to change the Bindings.Config file and the Client.Config where we store the actual URL for each endpoint.
This way we can change the endpoint from http to https and back again to test the app without having to change any code.
Hope this helps.
You can (should) use CROSS JOIN
. Following query will be equivalent to yours:
SELECT
table1.columnA
, table2.columnA
FROM table1
CROSS JOIN table2
WHERE table1.columnA = 'Some value'
or you can even use INNER JOIN with some always true conditon:
FROM table1
INNER JOIN table2 ON 1=1
