d701 | train | You can just use a list for the sake of having a sorted - well - list. If you want to associate additional data, you could either use a tuple to store the data, or even create a custom object for it that stores the id in an additional field.
You shouldn’t need to extend the list for that, you can just put any object into a list. For example this would be easily possible:
>>> lst = [ ( 132, 'foobar' ), ( 58, 'other value' ) ]
>>> lst.append( ( 70, 'some data value' ) )
>>> lst
[(132, 'foobar'), (58, 'other value'), (70, 'some data value')]
>>> lst.sort( key=lambda x: x[0] )
>>> lst
[(58, 'other value'), (70, 'some data value'), (132, 'foobar')]
>>> lst.sort( key=lambda x: x[1] )
>>> lst
[(132, 'foobar'), (58, 'other value'), (70, 'some data value')]
edit:
In case you are using Python 3.1+, you could also use the collections.OrderedDict type. It is an extension to the normal dict which maintains the order just like list does.
A: Using lists or arrays is problematic when you need to do insertions or deletions -- these are O(n) operations which can be devastatingly slow with large datasets.
Consider using blist which has a list-like API but affords O(lg N) insertion and deletion.
A: why not using a dictionary, with the key as the item of original array, and value is the id related to the key.
of course you could access it in sorted order, like this:
a = {'key':'id'}
keys = a.keys()
keys.sort()
for k in keys:
print a[key]
A: Similar to poke's answer, you can use a 2d array -- but if the arrays are big, NumPy is generally a good bet for any kind of numerical data in Python. Just make a 2D array that looks like
[ [1 614.124]
[2 621236.139]
[3 1243.612] ]
and then you can sort with .sort(). | unknown | |
d702 | train | I suggest you do use w+b mode, but move writing to zipfile after closing the invoice XML file.
From what you wrote it looks as you are trying to compress a file that is not yet flushed to disk, therefore with w+b it is still empty at time of compression.
So, try remove 1 level of indent for invoices_package.write line (I can't format code properly on mobile, so can't post whole section). | unknown | |
d703 | train | First you should turn on error displaying in your iis, or read the error log for its description, google it if not sure how.
Without error description, it's way too difficult to check what is wrong.
A: Problem solved!
After banging my head against the wall for a day i found out that i stupidly declared the array inside the DO WHILE loop. Moved the declaration out of it and problem solved. | unknown | |
d704 | train | You shouldn't add the templatetags directory to installed apps. You should put the templatetags directory inside an existing app, and add that to installed apps.
A: Try to move templatetags folder to logicalhp
A: Part of the problem was a typo in my settings.py (wrote the 'logicalhp.templatetags' when it was in 'itslogical'). The larger problem was that it was trying to get the attribute "STATIC_URL" from my settings. It included the quotes, so it was effectively settings.__getattr__('"STATIC_URL"').
To fix it, I added a strip.
return settings.__getattr__(str(self.arg)) #before
return settings.__getattr__(str(self.arg).strip('"')) #after
(By the way, it's not like you can omit the quotes in the template; else it think's its a variable. ) | unknown | |

d706 | train | Update:
Please see the following tech note for iOS 8 support: http://www-01.ibm.com/support/docview.wss?uid=swg21684538
The link includes download links for patched versions of Worklight 5.0.6, 6.0, 6.1 and 6.2 as well as a list of fixed issues and other instructions.
*
*The relevant iFix is that from September 18th at the least.
*The fix is Studio-only.
*Users of Worklight 6.1.0.x should use the iFix from September 19th containing an App Store submission bug fix.
*Users of Worklight 6.0.0.x should also delete the wlBuildResources folder from the tmp directory prior to generating the fixed version (close Eclipse > Delete > Open Eclipse).
*Due to the nature of the defect (in native code, before the Worklight framework initializes), there are no alternatives other than the below...
Scenarios:
*
*If a user has already upgraded to iOS8 and the application got stuck on the splash screen, AFAIK the way to handle it is to either:
*
*Uninstall/re-install the application from the App Store.
*Install a newer app version (see below) from the App Store.
*If a user did not yet upgrade to iOS8, it is best to use the fixed Worklight Studio to generate an updated app, increment its version and re-publish it. Then, Remote Disable the existing version and direct users to install the fixed version from the App Store; the fixed version should then continue to work after upgrading to iOS8.
Old:
Worklight in general does support iOS 8, but this is a specific scenario that requires further investigation. Thanks for the report, We're going to look into it. | unknown | |
d707 | train | First of all, the class AlexaViewSet is not a serializer but a ViewSet. You didn't specify the serializer class on that ViewSet so I you need to specify that.
On the other side, if you want to pass a custom query param on the URL then you should override the list method of this ViewSet and parse the query string passed in the request object to retrieve the value of group_by, validate it, and then perfom the aggregation youself.
Another problem that I see is that you also need to define what is to aggregate a JSON field, which is not supported in SQL and it's very relative, so you may want to consider redesigning how you store the information of this JSON field if you want to perfom aggregations on fields inside it. I would suggest extracting the fields you want to aggregate from the JSON (when storing them in the database) and put them in a SQL column separately so you could perform aggregations later.
The client could also pass the agregation operation as a query parameter, for example aggregation=sum or aggregation=avg.
In a simple case, where you just need the average of the ranks this should be useful as an example (you could add TruncQuarter, etc.):
class AlexaViewSet(viewsets.ModelViewSet):
serializer_class = AlexaSerializer
queryset = Alexa.objects.all()
filter_fields = {'created_at': ['iexact', 'lte', 'gte']}
http_method_names = ['get', 'post', 'head']

d708 | train | you should check if your database has data that doesn't fit like an id value that is not present in the foreign table, delete any rows like that and the migration should work, it would help if you let us know what npm run deploy:fresh does, you might be doing something else wrong if the data is not clearing on a clean migration
A: You need to use the same data type in both tables when using foreign keys. As an example, if you are using 'uuid' for id in agegroups table, then you must use uuid for users table foreign key (age_group_id)also. But here you used 'text' data type for foreign key. Please check whether both data types are similar or not. | unknown | |
d709 | train | If you want the Dialog Border to appear in any colour you wish you have to use layout style and a theme. There is an excellent article about it here: http://blog.androgames.net/10/custom-android-dialog/ | unknown | |
d710 | train | .single('parameter') means the input field's name is 'parameter'
In your case:
app.use(multer({dest: './app/controller/store'}).single('photo'));
You passed a 'photo' argument into single func.
Then your form should look like this, change it:
..
..
<input type="file" name="photo">
..
.. | unknown | |
d711 | train | Though it may be more complicated, why not just have an onmousedown event on the <p> element, and thet event will then attach an onmousemove event and onmouseout event, so that if there is a mouse movement, while the button is down, then remove the class on the span elements, and once the user exits, the element then you can put them back.
It may be a bit tricky, and you may want to also look for key presses, or determine other times you want to know when to put back the css classes, but this would be one option, I believe.
A: It sounds like you need to go one step further and on highlight, remove the <span> and save a reference to it. Once the highlight is finished, re-insert the reference to the object.
// copy start detected
var savedTooltip = $('.tooltip').remove();
// later that day when copy finished
$('p').append(savedTooltip);
If position of the <span> in your markup is important, you'd have to create a temporary reference element so you'd know where to re-insert it in the DOM. | unknown | |
d712 | train | you should to do several things but I think you don't
do that.
I create a simple project only for you and added to my GitHub
just click in this link: GitHub first Project templates
if it is helpful please, take a vote.
A: First of all, you wrote scr, not src and this should be corrected.
<!--It doesn't work-->
<img scr="{% static "first_app/yp.jpg" %}" alt="oh oh">
After that you may need to clear "first_app/" part from your code, because you are adressing your directory directly in settings file. | unknown | |
d713 | train | I've had this problem before, and if I recall correctly it had something to do with iOS not knowing the actual size until after the view has been drawn the first time. We were able to get it to update by refreshing after viewDidAppear (like you mentioned it's the appropriate size after refreshing), but that's not exactly the nicest solution.
Something else you could try is adding constraint outlets to the cell that you manipulate wherever you do your cell setup. For example, if you needed a UI element to be a certain width in some cases but not others, you could add a width constraint that you change the value of. This lets your other elements resize themselves based on the other constraints in the view. The limitation here is that you need to know the width of one of your elements beforehand. | unknown | |
d714 | train | Reference for CardView. It is just a RelativeLayout with a rounded corners and a drop shadow. So yes, the image was probably an image of a layout designed with CardViews. At the same time, it could also just be a layout that was custom built and a shadow drawn behind it, if that developer wanted to do the work themselves. You can easily replicate the layout by creating this in xml, I can provide an example if necessary.
The CardView is not JUST designed for RecyclerView's but looks really good in a RecyclerView as the layout that is inflated IF a CardView layout makes sense to use. Again, it's just a RelativeLayout with extra features (rounded edges, and shadow) | unknown | |
d715 | train | You can do this by enabling two-phase rendering: https://www.ibm.com/support/knowledgecenter/en/SSHRKX_8.5.0/mp/dev-portlet/jsr2phase_overview.html.
Enable two-phase rendering in the portlet.xml like this:
<portlet>
...
<container-runtime-option>
<name>javax.portlet.renderHeaders</name>
<value>true</value>
</container-runtime-option>
</portlet>
Then you can set the headers within the doHeaders method by using the setProperty or addProperty response methods:
@Override
protected void doHeaders(RenderRequest request, RenderResponse response) {
response.addProperty("MyHeader", "MyHeaderValue");
} | unknown | |
d716 | train | You sended string to model but you must send collection to model and then show in table
A: Your view is expecting IEnumerable<Website.Models.OrderIndexViewModel> as the model but you are passing it a single instance of Website.Models.OrderIndexViewModel.
This might be another bug in your code, as this will only ever render the last item from the select statement. So you'll want something like this, which will render a row for each result:
var orders = new List<OrderIndexViewModel>();
while (reader.Read())
{
var order = new OrderIndexViewModel();
order.CustomerOrderId = reader.GetInt32(0);
order.FirstName = reader.GetString(1);
order.ProductId = reader.GetInt32(2);
order.Name = reader.GetString(3);
order.Price = reader.GetDecimal(4);
orders.Add(order);
}
cnn.Close();
return View(orders); | unknown | |
d717 | train | When you use AND and OR together in any circumstances in any programming language ALWAYS use brackets. There is an implicit order which gets evaluated first (the AND or the OR condition) but you usually don't know the order and shouldn't be in need to look it up in the manual
Also use Prepared statements for SQL queries which depends on variables.
In your case you either write
... WHERE (host = ? OR challenger = ?) AND id = ?
or
... WHERE host = ? OR (challenger = ? AND id = ?)
depending on what condition you want.
Also, when a SQL query fails for whatever reason check the error message you get from the database. It will tell you whats wrong with the query. However, a valid query which returns no rows (because the WHERE condition don't match for any row) is still a valid query and not an error, the result is just empty. | unknown | |
d718 | train | I recommend trying it out for yourself, but the comment in the code
#TODO/XXX: Remove as_lookup_value() once we have a cleaner solution
# for dot-notation queries
suggests that it does. I've ever only really used lists.
A: You can filter for a Post that has an author named "Ralph" using raw queries:
Post.objects.raw_query({'author.name': "Ralph"}) | unknown | |
d719 | train | I found a way. Just add httpServletRequest.getSession().setMaxInactiveInterval(intervalInSeconds)
@RequestMapping(value = "/login", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE)
public String login(HttpServletRequest request, HttpServletResponse servletresponse){
//Your logic to validate the login
request.getSession().setMaxInactiveInterval(intervalInSeconds);
}
This worked for me.
EDIT 1
Found another way to do this. This would be the correct way of doing this,
@EnableJdbcHttpSession(maxInactiveIntervalInSeconds = intervalInSeconds) | unknown | |
d720 | train | The string is slightly incorrect, but I hope all other requirements are met:
// Create a font
XFont font = new XFont("Verdana", 12, XFontStyle.Bold | XFontStyle.Underline);
// Draw the text
gfx.DrawString("Hello, World!", font, new XSolidBrush(XColor.FromArgb(255, 0, 0)),
100, 100,
XStringFormats.Center); | unknown | |
d721 | train | In your yamls, there is a path "/?..." for handling the query parameters but this path will not receive traffic from "/" path as there is no prefix match. So you have to create a path "/" with type prefix to solve the issue. Then you can ignore current "/?..." path as it will match prefix with "/" path.
Please try this:

d726 | train | There might be a more elegant solution but you can loop through the response_date values in df2 and create a boolean series of values by checking against the all the response_date values in df1 and simply summing them all up.
df1['group'] = 0
for rd in df2.response_date.values:
df1['group'] += df1.response_date > rd
Output:
summary participant_id response_date group
0 2.0 11 2016-04-30 0
1 3.0 11 2016-05-01 1
2 3.0 11 2016-05-02 1
3 3.0 11 2016-05-03 1
4 3.0 11 2016-05-04 1
Building off of @Scott's answer:
You can use pd.cut but you will need to add a date before the earliest date and after the latest date in response_date from df2
dates = [pd.Timestamp('2000-1-1')] +
df2.response_date.sort_values().tolist() +
[pd.Timestamp('2020-1-1')]
df1['group'] = pd.cut(df1['response_date'], dates)
A: You want the .cut method. This lets you bin your dates by some other list of dates.
df1['cuts'] = pd.cut(df1['response_date'], df2['response_date'])
grouped = df1.groupby('cuts')
print grouped.max() #for example | unknown | |

d729 | train | You can add it to some other app, or even create just a file called static in the root of project_name and refer to the class inside this file in your settings.INSTALLED_APPS directly, but the recommended way to provide AppConfigs is inside an apps.py file inside the application package.
If you have no app where this AppConfig could be placed, I think the best practice would be to create a package under project_name.project_name called static, with only an init.py file and an apps.py file.
In this file you can create your AppConfig in the way you described.

A: After some searching, I saw a few examples on the internet where they use
a getSupportLoaderManager().initLoader(1,null,this).forceLoad();. That seems to work. also calling loader.forceLoad() in the onCreateLoader() works too. On further checking, I saw this : https://issuetracker.google.com/issues/36925900
It seems we have to implement forceLoad in onStartLoading() as thus:
protected void onStartLoading() {
if (mCursor != null) {
deliverResult(mCursor);

if (takeContentChanged() || mCursor == null) {
forceLoad();

d740 | train | i have found the issue, posting if will help somebody else.
the problem was that mysqld went into infinite loop trying to create indexing to a specific database, after found to which database was trying to create the indexes and never succeed and was trying again and again.
solution was to remove the database and recreate it, and the mysqld process went back to normal. and the infinite loop to create indexes dissapeared as well.
A: I would say increasing connection may solve your problem temperately.
1st find out why the application is not closing the connection after completion of task.
2nd Any slow queries/calls on the DB and fix them if any.
3rd considering no slow queries/calls on DB and also application is closing the connection/thread after immediately completing the task, then consider playing with "wait_timeout" on mysql side.
A: According to this answer, if you have MySQL 5.7 and 5.8 :
It is worth knowing that if you run out of usable disc space on your
server partition or drive, that this will also cause MySQL to return
this error. If you're sure it's not the actual number of users
connected then the next step is to check that you have free space on
your MySQL server drive/partition.
From the same thread. You can inspect and increase number of MySQL connections. | unknown | |
d741 | train | You can create a text node and append it to the parent of img, and optionally remove img if needed. This code goes inside the error handler for img
$('img').on('error', function(){
$(this).parent().append($('<div>Broken image</div>'));
$(this).remove();
})
A: Ok, I think I have found a solution for you. I tried to use jQuery error function. This one helped me:
To replace all the missing images with another, you can update the src attribute inside the callback passed to .error(). Be sure that the replacement image exists; otherwise the error event will be triggered indefinitely.
In your example this would be the best:
$('img').each(function() {
var img = $(this);
img.error(function() {
img.replaceWith('<div class="error404">Image not found (error 404)</div>');
}).attr('src', img.attr('src'));
});
I also made a jsFiddle example for you, which is working great for me.
A: If you really need to use javascript for this try
$(document).ready(function() {
$('img').attr('alt', 'Alternative text');
});
But the same is achievable by barebone HTML
<img src="path/to/image.jpg" alt="Alternative text">
A: You can change the alt if an error is thrown just like you're doing with the image.
function imgMissing(image) {
image.onerror = "";
image.alt = "Image not Found";
return true;
}
The HTML:
<img src="image.jpg" onerror="imgMissing(this);" >
A: EDIT: OK, I have found this solution working fine:
<script type="text/javascript">
$(document).ready(function() {
$('.post_body img').one('error', function() {
$(this).replaceWith('<div>Image not found (error 404)</div>');
});
});
</script>
Anyway one more think, I need to add CSS class "error404" for this "div", how to do that in JS? Thank you very much!
CSS will be:
.error404 {
display: block;

d743 | train | Your code has undefined behavior.
You cannot validly access the memory pointed at by an uninitialized pointer, like you do.
The memset() function writes to memory, it does not magically allocate new memory (it takes as input the pointer to the memory to be written), you cannot in anyway use it "instead of" malloc().
You can try with an on-stack buffer:
char log[128] = "";
of course you need to take care not to use more than 128 characters; your unbounded strcat() usage is dangerous.
If your fringe compiler supports C99 you can of course do:
const size_t flen = strlen(func);
const size_t mlen = strlen(msg);
char log[flen + 2 + mlen + 1]; // Space for func, msg, colon, space, terminator.

d744 | train | I got the same error message in a new java installation when trying to use an SSL connection that enforces 256-bit encryption. To fix the problem I found I needed to install the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files (e.g. http://www.oracle.com/technetwork/java/javase/downloads/jce-7-download-432124.html)
A: I had this line
SSLContext sc = SSLContext.getInstance("SSL");
Had to change it to
SSLContext sc = SSLContext.getInstance("TLSv1");
And now it works on both, java 7 and java 8
Note: (In java 7 SSL and TLS both worked with the same url, in java 8 just tried TLSv1 but I guess SSLv1 also works)
A: Download the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files according to your JDK/JRE version and put it in lib/security folder
By default,Java Cryptographic Extension is limited in accessing function and algorithm usage.We need to make it unlimited.
A: According to the stack trace, the RecordVersion Unknow-0.0 is produced from here
=> referenced from here => which is invoked in InputRecord.readV3Record
most of the time, these two values should not be 0, the reason for this happening is probably the wrong response from server while handshaking.

d754 | train | Let me just expand a little bit what you've already been told in comments.
That's how by-name parameters are desugared by the compiler:
@tailrec
def factorialTailRec(n: Int, f: => Int): Int = {
if (n == 0) {
val fEvaluated = f
fEvaluated
} else {
val fEvaluated = f // <-- here we are going deeper into stack.
factorialTailRec(n - 1, n * fEvaluated)
}
}
A: Through experimentation I found out that with the call by name formalism, the method becomes... non-tail recursive! I made this example code to compare factorial tail-recursively, and factorial non-tail-recursively:
package example
import scala.annotation.tailrec
object Factorial extends App {
val ITERS = 100000
def factorialTailRec(n: Int) : Int = {
@tailrec
def factorialTailRec(n: Int, f: => Int): Int = {
if (n == 0) f else factorialTailRec(n - 1, n * f)
}
factorialTailRec(n, 1)
}
for(i <-1 to ITERS) println("factorialTailRec(" + i + ") = " + factorialTailRec(i))
def factorial(n:Int) : Int = {
if(n == 0) 1 else n * factorial(n-1)
}
for(i <-1 to ITERS) println("factorial(" + i + ") = " + factorial(i))
}
Observe that the inner tailRec function calls the second argument by name. for which the @tailRec annotation still does NOT throw a compile-time error!
I've been playing around with different values for the ITERS variable, and for a value of 100,000, I receive a... StackOverflowError!
(The result of zero is there because of overflow of Int.)
So I went ahead and changed the signature of factorialTailRec/2, to:
def factorialTailRec(n: Int, f: Int): Int
i.e call by value for the argument f. This time, the portion of main that runs factorialTailRec finishes absolutely fine, whereas, of course, factorial/1 crashes at the exact same integer.
Very, very interesting. It seems as if call by name in this situation maintains the stack frames because of the need of computation of the products themselves all the way back to the call chain. | unknown | |

d761 | train | I am going to explain how it works. But the code you have written is correct. Even I ran the code.
let express = require('express');
let app = express();
app.use(express.static('../html&css'));
let server = app.listen(8080, function () {
app.get(function (req, res) {
res.sendFile();
});
});
let port = server.address().port;
console.log(`Express app listening at ${port}`);
Now, what express.static do? it exposes the particular folder and makes auto routes.
If you want to access main.css it will be hosted on localhost:8080/main/main.css
In the main.html to use that CSS you just add a link.
<link rel="stylesheet" href="main.css"> or <link rel="stylesheet" href="/main/main.css">
But, you cannot HTTP GET let's say localhost:8080/main that will not work.
So, you need to run the server by typing node javascript/server.js and it will run just fine. But as the server.js is a backend code do not put it in the public folder. Maybe make a folder called src and put it there.
A: Let's look a a few things.
First, folder structure:
According to your setup, you have your server.js file embedded within the public folder, albeit one level down.
If you think of an MVC framework, see this sample tutorial, you want to put your server at the root of your application (not inside of the JavaScript folder inside public where you would serve any client-side javascript.
Second, regarding middleware:
When you call the express.static middleware, you will want to use the path module to create an absolute rather than relative path to the public folder, which is especially important for deployment.
app.use(express.static(path.join(__dirname, 'public')));
Now, you will be able to access all the files in your public folder like so:
http://localhost:8080/main/*
http://localhost:8080/javascript/*
Of course * refers to whatever files are there.
Third, regarding app.listen:
The callback to app.listen is expecting to be returned a server object. See the documentation. Rather than setting up a listener on a route here, you should establish that outside of the app.listen call.
For instance, you may want to set up a basic get route to serve your main.html page on /. That's up to you. The express.static middleware is already serving this page as /main/main.html.
app.get('/', function (req, res) {
res.sendFile(path.join(__dirname, 'public', 'main.html'));
});
let server = app.listen(8080); | unknown | |

d765 | train | In JavaScript, variables and functions can't have the same name. (More confusingly: functions are variables!)
So that means that this line:
let hour = hour();
Is not allowed, because you're trying to reassign the hour variable from being a function to being a value. (This is a side effect of using let. If you had used var then this would have silently did the wrong thing.)
To fix the problem, just rename your variable to something that's not already a function.

better you do some checks first if you go for this solution.
if you implement your solution with foreach which is in this case more readable, you can increment or decrement a given variable, like normal:
$i++; //if you want the increment afterwards
++$i; //if you want the increment before you read your variable
the same for decrements:
$i--; //decrement after reading the variable
--$i; //decrement before you read the variable
A: A foreach loop is just a better readable for loop. It accepts an array and stores the current key (which is in this case an index) into $k and the value into $v.
Then $v has the value you are using in the snippet of code.
A for loop does only accept indexed arrays, and no associative arrays.
We can rewrite the code by replacing $v with $orgs[ index ], where index starts from 0.
$r = "";
$j = 0;
for ($i = 0; $i < count($orgs); $i++) {
echo "\n\r" . $orgs[$i]->id . "\n\r";
if (1) {
$a_view_modl = ArticleView::model($orgs[$i]->id, $orgs[$i]->id);
$connection = $a_view_modl->getDbConnection();
A: $r = "";
$j = 0;
for($i = 0 ; $i < count($orgs); $i++)
{
$v = $orgs[$i];
echo "\n\r" . $v->id . "\n\r";
if (1) {
$a_view_modl = ArticleView :: model($v->id, $v->id);
$connection = $a_view_modl->getDbConnection();
}
A: foreach ($orgs as $k => $v) {
// Your stuff
}
for loop
for ($i = 0; $i < count($orgs); $i++) {
// Your stuff ... use $orgs[$i];

d768 | train | I have done several projects involving scraping websites to obtain thousands of stock prices each day. The problem, as dano suggested, is related to your error handling:
except Exception as e:
return None
This does nothing to handle failed requests. You can append the failed urls to a list, and at the end of your script run your "get" function again with those urls. If your information is critical, you can even define a function that tries at least 5-10 times to download the information of a stock before it returns None.
More related to the multithreading question, you need to be careful with the number of requests per second/minute/hour and avoid exceeding the API/website rate limit. You can use multiple proxies for that.
Hope it helps. | unknown | |
d769 | train | Your Program class is defined as implementing the Runnable interface. It therefore must override and implement the run() method:
public void run () {
}
Since your two Thread objects are using anonymous inner Runnable classes, you do not need and your should remove the implements Runnable from your Program class definition.
public class Program {
...
A: try this:
class Program {
public static void main(String[] args) {
Thread thread1 = new Thread() {
@Override
public void run() {
System.out.println("test1");
}
};
Thread thread2 = new Thread() {
@Override
public void run() {
System.out.println("test2");
}
};
thread1.start();
thread2.start();
}
Or you can create a separate class implementing Runnable and ovverriding method run().
Then in main method create an instance of Thread with you class object as argument :
class SomeClass implements Runnable {
@Override
run(){
...
}
}
and in main:
Thread thread = new Thread(new SomeClass());
A: When you implement an interface (such as Runnable) you must implement its methods, in this case run.
Otherwise for your app to compile and run just erase the implements Runnable from your class declaration:
public class Program {
public void main (String[] args) {
Thread thread1 = new Thread () {
public void run () {
System.out.println("test1");
}
};
Thread thread2 = new Thread () {
public void run () {
System.out.println("test2");
}
};
thread1.start();
thread2.start();

d770 | train | Using dynamically created progress bar or referencing it from an id, are both fine.
Using a reference from XML allows you to have more control on the progress bars appearance, as you would have designed it sepcifically for your need (like appearance, where it has to appear, etc..). But if that is not the case, you can use a dynamically created one as in your current code as well.
A: There is a lot of ways. One is to define ProgressDiaolog as a field in your AsyncTask, then add it to your onPreExecuted():
pDialog = new ProgressDialog(this);
pDialog.setMessage("some downloading massage");
pDialog.setIndeterminate(false);
pDialog.setMax(100); //you can adjust this
pDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
pDialog.setCancelable(false);
pDialog.show();

d775 | train | I take no credit for this since I got every bit of it from going through multiple StackOverflow threads, but I got this working with:
@interface MyViewController ()
- (IBAction) toggleSettingsInPopover: (id) sender;
@property (nonatomic, strong) UIStoryboardPopoverSegue *settingsPopoverSegue;
@end
@implementation MyViewController
@synthesize settingsPopoverSegue = _settingsPopoverSegue;
- (IBAction) toggleSettingsInPopover: (id) sender {
if( [self.settingsPopoverSegue.popoverController isPopoverVisible] ) {
[self.settingsPopoverSegue.popoverController dismissPopoverAnimated: YES];
self.settingsPopoverSegue = nil;
} else {
[self performSegueWithIdentifier: @"Settings" sender: sender];

- (void) prepareForSegue: (UIStoryboardSegue *) segue sender: (id) sender {
if( [segue.identifier isEqualToString: @"Settings"] ) {
if( [segue isKindOfClass: [UIStoryboardPopoverSegue class]] )
self.settingsPopoverSegue = (UIStoryboardPopoverSegue *) segue;
MySettingsViewController *msvc = segue.destinationViewController;
msvc.delegate = self;
}
}
@end
In my storyboard I control-dragged from my settings bar button item to MyViewController and connected it to the toggleSettingsInPopover action. Then I control-dragged from MyViewController to the view for the settings to create the segue, set its type to popover, set its identifier to Settings, set its directions to up and left (the toolbar is at the bottom of the screen and the button is at the right end), then dragged from its Anchor to the bar button item I connected to the action.
A: You have to anchor the segue to the UIBarButton by Ctrl-Dragging the Anchor Field from the segue Attribute Inspector to the UIBarButton.
If you do it the opposite way, Ctrl-Dragging from the Button to the Window to be shown you won't have a possibility to control the behaviour from the Popoverwindow.

d776 | train | So I feel your pain in refactoring all of your code. We went through the same thing with one of our apps at work and it was a pain. On the backside of it though, well worth it! The way ionic suggests you to organize your files is not sustainable. I have a couple thoughts and ideas for you based on going through the same thing that might help you out.
First off, putting everything back in the same module is not the best idea, because then you end back where you started with the disorganized code as ionic would have you do it, rather than the organized code as Angular suggests. In general, Angular suggests some great patterns, and I think it's worth the struggle to get your code in line with their suggestions.
Secondly, and this is the main point, are you using deep links in your app? If you are, there is a fantastic, barely documented feature you get with deeplinks to avoid circular dependency within pages. Suppose you have a page with the following deep link config:
{
component: MyCoolPage, // the page component class
name: 'MyCoolPage', // I use the name of the class but can be any sting you want
segment: 'cool-page' // optional, not related to the problem,
// but it's probably best to use this field as well
}
Whenever you want to navigate to MyCoolPage, instead of doing navCtrl.push(MyCoolPage), you can now do navCtrl.push('MyCoolPage') // or whatever string name you gave the page. So now you're navigating to pages via string names, which eliminates the need for importing pages whenever you want to navigate to it. This feature has existed since ionic 2, although I did not realize you could do this until updating to ionic 3.
Thirdly, more of a design consideration than anything else, you might want to reconsider navigating to pages from within components. Generally what we do is emit events up to the parent page components, and then have the page component handle pushing or popping the nav stack. Your BookListItemComponent shouldn't be causing you problems. If that is something in the shared module, used throughout the app, it shouldn't be depending on other modules. Your shared module shouldn't depend on anything else besides the ionic and angular modules you need to import. | unknown | |

d783 | train | You can copy above code snippet as a service configuration to your services.yaml, which probably roughly looks like this:
# app/config/services.yaml
services:
app.memcached_client:
class: Memcached
factory: 'Symfony\Component\Cache\Adapter\MemcachedAdapter::createConnection'
arguments: [['memcached://my.server.com:11211', 'memcached://rmf:abcdef@localhost']]
app.memcached_adapter:
class: Symfony\Component\Cache\Adapter\MemcachedAdapter
arguments:
- '@app.memcached_client'
Then in your configuration you should be able to reference the adapter using the client created by the factory, e.g. something like:
# app/config/config.yaml
framework:
cache:
app: app.memcached_adapter
You might also be able to overwrite the default alias cache.adapter.memcached instead of having your own adapter.
Your approach using Memcached::addServer might work as well, but just like with MemcachedAdapter::createConnection this will return the Client, which needs to be passed to the cache adapter. That's why there is a second service app.memcached_adapter, which is used in the cache configuration.
Please be aware that I have not tested this, so this is rather a rough outline than a fully working solution,
A: For one of my projects running Symfony 3.4 the configuration was simpler:
Create a service that will be used as a client:
app.memcached_client:
class: Memcached
factory: ['AppBundle\Services\Memcached', 'createConnection']
arguments: ['memcached://%memcache_ip%:%memcache_port%']
The AppBundle\Services\Memcached can have all the custom logic I need like so:
class Memcached
{
public static function createConnection($dns)
{
$options = [
'persistent_id' => 'some id'
];
// Some more custom logic. Maybe adding some custom options
// For example for AWS Elasticache
if (defined('Memcached::OPT_CLIENT_MODE') && defined('Memcached::DYNAMIC_CLIENT_MODE')) {
$options['CLIENT_MODE'] = \Memcached::DYNAMIC_CLIENT_MODE;
}
return \Symfony\Component\Cache\Adapter\MemcachedAdapter::createConnection($dns, $options);
}
}
And then I used that service in my config.yml:

d787 | train | As they wrote here, htaccess works in all directories except cgi-bin. But, as you can see from here, there's a way around it.
Basically, you edit the <Directory "C:/path/to/cgi-bin"> section of your httpd.conf file - and put there whatever would have been in the .htaccess file in cgi-bin.
Remember to restart your apache after changes to httpd.conf
One more tidbit: there's probably already a <Directory "/var/www/cgi-bin"> in your httpd.conf. Edit it - having duplicate sections causes gray hairs.
The above worked for me for password protecting the cgi-bin directory, as using .htaccess in cgi-bin didn't work. Inserting it into the <Directory "C:/path/to/cgi-bin"> section of my httpd.conf file did work.
It now says:

d800 | train | Are you running in development or production mode?
SHOW FIELDS FROM foo is done by your model, as you noted, so it knows which accessor methods to generate.
In development mode, this is done every request so you don't need to reload your webserver so often, but in production mode this information should be cached, even if you're running a three year old version of Rails.
A: This is called by ActiveRecord reading the attributes of a model from your database. It won't happen multiple times in production, but in development mode, Rails queries the table each time to pick up on any changes that may have occurred.
A: If you have this kind of problem again and need to track down how a query is being called I would suggest the Query Trace plugin: http://github.com/ntalbott/query_trace/tree/master. It adds a stack trace to the log for every SQL query. Very handy.
A: This line actually comes from calling the model, i had an array in the application controller that looked like [Model1, Model2, Model3] and I changed it to look like ['Model1','Model2', 'Model3'] and that fixed all the extra calls. | unknown |
