d5286 | train | I faced same problem, finally I solve it using this code to
pass integer value to Bigdecimal
payment.setSubtotal(new BigDecimal("10"));
instead of using:
payment.setSubtotal(new BigDecimal(10));
e.g.:
public void onClick(View v) {
PayPalPayment payment = new PayPalPayment();
payment.setSubtotal(new BigDecim... | unknown | |
d5287 | train | The assign() function has a twin called get(). This is the function that you need.
Refer to this concise and easy-to-understand article here. | unknown | |
d5288 | train | The comment in the question about the requirements inspired me to implement this in terms of k * step instead of some other mechanism controlling the number of iterations over the container.
template <class Container>
void go(const Container& C)
{
const size_t sz = C.size();
if(idx >= sz) return;

d5289 | train | xargs -P 10 | curl
GNU xargs -P can run multiple curl processes in parallel. E.g. to run 10 processes:
xargs -P 10 -n 1 curl -O < urls.txt
This will speed up download 10x if your maximum download speed if not reached and if the server does not throttle IPs, which is the most common scenario.
Just don't set -P too hig... | unknown | |
d5290 | train | I found the solution myself.
I seems I had the limit of 10 Google Cloud projects (the standard limit I think), and since Firebase actually uses Google Cloud as well, then I had to delete some old Google Cloud projects I did not use anymore.
Then my old firebase projects showed up in the new Firebase console and I could... | unknown | |
d5291 | train | Yes, there are lot of ways that this can be handled. A simple google search could have helped you out.
The most simple way is to set OnClickListener() for the Login Button. The listener method will be called when the button is clicked.
Inside the method, you can check if the Edittext field is empty using the TextUtils.... | unknown | |
d5292 | train | Change single quote to double quotes. Note that variables inside the single quotes would not be parsed.
header("Location: $v1");
A: Wrong syntax. Try:
$url = "http://www.google.com/";
header("Location: $url");
// ^ ^
// You should use double quotes to expand variables.
A: This worked for me:

d5293 | train | First of all, buffers are backed by the smalloc module and this module was not added by io.js devs, it was initiated in node 0.11 branch, io.js just imported it. Raw memory allocation means a lower level of memory manipulation and thus - faster operations, better performance, which is what aims both node.js and io.js. ... | unknown | |
d5294 | train | souldn't you just do this?
export class HeaderMainComponent {
logoAlt = 'We Craft beautiful websites'; // Logo alt and title texts

isMenuShown: false;
constructor(private layoutService: LayoutService, private renderer: Renderer) { }

d5295 | train | I believe you are asking how to load and store a shared list of content, that all users using the application can access. This is so that each time a user loads a page you don't have to load the contents from a database.
This can be done easily with Java, as you mentioned, but with PHP you'll have to push shared applic... | unknown | |
d5296 | train | The trick is not to have your ui code and server code in two seperate files but to write a function which contains your ui and server code.
Try this:
shinyapp <- function(mat) {
app <- list(
ui = bootstrapPage(
here comes your ui.R),
server = function(input, output) {

d5297 | train | You need to do a include 'AdminTab.php'; as well, since your class extends that
A: Not completely sure I understand your question, are you saying that you have static class "B" which extends class "A", "A" having your regenerateThumbnailsCron() method which you want to call before anything else?
If so then try this:

d5298 | train | Qt GUIs can be displayed in many themes. native="true" forces the application to use the operating system's theme (on Linux, some QT apps look terrible because they don't look like the rest of the native apps). | unknown | |
d5299 | train | This is how I did it, without collection (doesn't seem to have a shortcut to doing it with collection operators); basically it's just a nested fetch request:
func dailyitems() -> [(date: String, items: [Item])]?
{
let request = NSFetchRequest(entityName: ItemEntity);
request.returnsDistinctResults = true;

d5300 | train | I recommend using Rome:

SyndFeed feed = new SyndFeedImpl();
feed.setFeedType("rss_2.0");
feed.setTitle("Sample Feed");
feed.setLink("http://example.com/");
// Feed entries
List entries = new ArrayList();
feed.setEntries(entries);
SyndEntry entry = new SyndEntryImpl();
entry.setTitle("Entry #1");
