d5801 | train | The above error occurs when the Stripe Secret API key is passed incorrectly.
Just for the help,
const Stripe = require('stripe');
const stripe = Stripe(env.STRIPE_TEST_SECRET_KEY);
make sure you change the key as per the production/development environment.
Cheers. | unknown | |
d5802 | train | I think you're looking for this:-
@Temporal(TemporalType.TIMESTAMP)
@Column(name = "curr", length = 10)
public Date getCurrrent() {
return this.currrent;
}
A: What Jelies mentioned is the correct approach. You simply instantiate the date object with
private Date currrent = new Date();
during object creation and then persist it.
To add on to that, its not safe to use @Temporal(TemporalType.TIMESTAMP) for storing the date and time, if there is a chance of you comparing the field current with any java.util.Date objects as the saved field will be loaded as java.sql.Timestamp. The reason is mentioned here.
Note: This type is a composite of a java.util.Date and a separate nanoseconds value. Only integral seconds are stored in the java.util.Date component. The fractional seconds - the nanos - are separate. The Timestamp.equals(Object) method never returns true when passed a value of type java.util.Date because the nanos component of a date is unknown. As a result, the Timestamp.equals(Object) method is not symmetric with respect to the java.util.Date.equals(Object) method. Also, the hashcode method uses the underlying java.util.Date implementation and therefore does not include nanos in its computation.
Due to the differences between the Timestamp class and the java.util.Date class mentioned above, it is recommended that code not view Timestamp values generically as an instance of java.util.Date. The inheritance relationship between Timestamp and java.util.Date really denotes implementation inheritance, and not type inheritance.
The work around is to use TypeDef. This post discusses about the issue and the workaround. The code used there will be good enough for you.
A: I think the easiest way to achieve that is to initialize your field with the new Date():
private Date currrent = new Date();
IMHO, I don't recommend changing the behavior of the setter method, other developers will not expect that.
If you want this field to be filled immediately before the entity is persisted/updated, you can define a method with @PrePersist or @PreUpdate JPA annotations to populate current property then. | unknown | |

d5804 | train | It's a function taking XElement as argument and returning an XElement, so for instance:
public XElement someFunction(XElement argument)
{
XElement someNewElement = new XElement();
... // do something with someNewElement, taking into account argument
return someNewElement;
}
Func<XElement, XElement> variableForFunction = someFunction;
.... .Select(variableForFunction);
I'm not interely sure if you have to assign it to a variable first, you could probably just do this:
... .Select(variableForFunction);
give it a try (and let me know if it works :) )
oh and for more information, here's the msdn article, it also explains how to use delegates:
Func<XElement, XElement> variableForFunction = delegate(XElement argument)
{
....//create a new XElement
return newXElement;
}
and how to use lambdas, for instance:
Func<XElement, XElement> variableForFunction = s => {
....;//create an XElement to return
return newXElement;
}
or, in this instance, use the lambda directly:
.... .Select( s => {
....;//create an XElement to return
return newXElement;

d5809 | train | The reason why you get null is because you are trying to get the id of Test before you add it to the DOM.
Where you have:
if(result.Verified === 'false'){
document.getElementById("Test").html("not verified")
}
$(context).html($('#Accounttmpl').render(result));
Change the order round:
$(context).html($('#Accounttmpl').render(result));
if(result.Verified === 'false'){
document.getElementById("Test").html("not verified")
}
Also, you are mixing JavaScript with jQuery here:
document.getElementById("Test").html("not verified")
Either do:
document.getElementById("Test").textContent = "not verified";
Or
$("#Test").html("not verified") | unknown | |
d5810 | train | The await keyword is only valid on places where asynchronous code is accepted.
The easiest here is to make the onSubmit funcion async.

A: React components cannot be made async like this. What you probably want is to execute an async callback once the button is clicked.
const onSubmit = async (e) => {
e.preventDefault();
let [res1, res2] = await Promise.all([ /* ... */ ]);
setFetchData(res1);

If you don't want your handler function itself to be async, you can also just call a new async function:
const onSubmit = (e) => {

let [res1, res2] = await Promise.all([ /* ... */ ]);
setFetchData(res1);

d5811 | train | Made working plunker for this:
Update:
I have updated the plunker and made it work with addHTML() function:
var pdf = new jsPDF('p','pt','a4');
//var source = document.getElementById('table-container').innerHTML;
console.log(document.getElementById('table-container'));
var margins = {
top: 25,
bottom: 60,
left: 20,
width: 522
};
// all coords and widths are in jsPDF instance's declared units
// 'inches' in this case
pdf.text(20, 20, 'Hello world.');
pdf.addHTML(document.body, margins.top, margins.left, {}, function() {
pdf.save('test.pdf');
});
You can see plunker for more details.
A: Change this in app.js:
pdf.addHTML(document.getElementById('pdfTable'),function() {
});
pdf.save('pdfTable.pdf');
for this one:
pdf.addHTML(document.getElementById('pdfTable'),function() {
pdf.save('pdfTable.pdf');
});
A: I took out everything but these:
<script src="//mrrio.github.io/jsPDF/dist/jspdf.debug.js"></script>
<script src="//html2canvas.hertzen.com/build/html2canvas.js"></script>
then I used this:
$(document).ready(function() {
$("#pdfDiv").click(function() {
var pdf = new jsPDF('p','pt','letter');
var specialElementHandlers = {
'#rentalListCan': function (element, renderer) {
return true;
}
};
pdf.addHTML($('#rentalListCan').first(), function() {
pdf.save("rentals.pdf");
});
});
});
I can print the table... looks great with chrome, safari or firefox, however, I only get the first page if my table is very large.
A: In app.js change:
pdf.addHTML(document.getElementById('pdfTable'),function() {
});
pdf.save('pdfTable.pdf');
to
pdf.addHTML(document.getElementById('pdfTable'),function() {
pdf.save('pdfTable.pdf');
});
If you see a black background, you can add to sytle.css "background-color: white;"
A: Instead of using the getElementById() you should use querySelector()
var pdf = new jsPDF('p','pt','a4');
pdf.addHTML(document.querySelector('#pdfTable'), function () {
console.log('pdf generated');

d5812 | train | I've tried to do the best I can with your code, the following will work for you:
<div class="container" style="overflow:hidden; text-align:center;">
<div style="display:inline-block; margin: 0px 80px;">
<div class="overlay">
<img class="img1" height="225" src="NYC/wtc1.JPG" width="225">
</div>
</div>
<div style="display:inline-block; margin: 0px 80px;">
<div class="overlay">
<img class="img2" height="225" src="NYC/wtcmem.jpg" width="225">
</div>
</div>
<div style="display:inline-block; margin: 0px 80px;">
<div class="overlay">
<img class="img3" height="225" src="NYC/sky.jpg" width="225">
</div>
</div>
</div>
Note that <overlay> is not a valid HTML element. also I've seen on the page you used something like <margin>. It's not a good practice to invent HTML elements.. You can get all the functionality you need using regular <div>s (although I don't think this will break your page.. maybe only in older browsers..).
What I basically did:
*
*Wrapped the three <div>s with a container with text-align:center. This will make the three divs inside it aligned to the center.
*Added display:inline-block; to make all the divs follow the text-align.
*Added margins to the divs to space them
Note that I strongly recommend to replace your <overlay> with something like <div class="overlay">
A: If you have some markup like this:
<div class="wrapper">
<div><img class="img1" height="225" src="http://rwzimage.com/albums/NYC/wtc1.JPG" width="225" /></div>
<div><img class="img2" height="225" src="http://rwzimage.com/albums/NYC/wtcmem.jpg" width="225" /></div>
<div><img class="img3" height="225" src="http://rwzimage.com/albums/NYC/sky.jpg" width="225" /></div>
</div>
Then I think this CSS will have approximately the effect you're after:
.wrapper {
display: table;
width: 960px;
}
.wrapper > div {
display: table-cell;
width: 33%;
text-align: center;
}
.wrapper > div:hover img {
opacity: 0.5;
}
Demo. I set width: 960px; so that it would force things to be wider than the JSFiddle window, but you could set width: 100%; for your page.
A: div tag naturally stack vertically. So you will need to add an id to each div or you could just put all the img in one div.
The block css attribute is effecting the layout. It is pushing the next img to the next line. | unknown | |

bis.close(); | unknown | |
d5814 | train | Dispose calls Flush, which writes the internal bytes stored in a buffer to disk
Without closing or disposing a file, you are leaving unmanaged resources around and will potentially lock the file, not to mention memory leaks. Instead always use a using statement
using (TextWriter writer = File.CreateText(@"...txt"))
{
writer.Write("Hello World");
}
However if you want to continually write to the file, you will have to flush it
FileStream.Flush Method
Clears buffers for this stream and causes any buffered data to be
written to the file.
TextWriter writer = File.CreateText(@"...txt");
...
writer.Write("Hello World");
...
writer.Flush(); // at this point the bytes are flushed to disk
...
...
writer.Dispose();
In short most streams are backed by an internal array (buffer), so you dont thrash writes. The Default size is 4k, when it hits the buffer size then it automatically flushes. If you want to see immediate writes, the you have to flush it every time
Lastly some streams have an auto flush feature, which can do this job for you
AutoFlush
Gets or sets a value indicating whether the StreamWriter will flush
its buffer to the underlying stream after every call to Write(Char)
When you are finished with the stream always dispose it | unknown | |

--, t.RechargeSN
FROM @tbl t
GROUP BY t.Userid, t.RechargeSN
ORDER BY t.Userid
A: Since you haven't posted any attempt to solve this, but have shown an understanding of the data, I assume you just need to be given a broad strategy to begin following, and you can handle the coding from there.
Using LAG() partitioned by UserID, you can join each row to the previous row. You already have stated that you understand that (Balance - SUM(Voice + Data)), so in any CASE where that is not true, then you know that you have found a row where a recharge was done.
You can create an artificial column (eg HasRecharge) in a CTE that uses a CASE expression to test this and return 1 for the rows that have a recharge, and 0 for the rows that don't.
Then you can do a 2nd CTE where you SELECT from the first CTE WHERE HasRecharge=1 and WHERE there EXISTS() a previous row that also HasRecharge=1. And calculate two additional columns:
A SUM of Voice + Data between this recharge and the last recharge (again using LAG() but this time WHERE HasRecharge=1)
A COUNT of rows between this recharge and the last.
Your final SELECT from the 2nd CTE would get the average simply by dividing the SUM column by the COUNT column.
A: This problem becomes simpler when you have a flat table containing the day's charge, and the previous day's charge. Note that this will only work if your data set has a contiguous range of dates.
The following queries will need to be edited of course:
Select
currentday.Date,
currentday.user,
currentday.balance - prevday.balance - (currentday.voice+currentday.data) as charge,
currentDay.voice,
currentDay.data,
--The above column will tell you what the difference
--is between the expected balance, and should
--resolve to the charge for the day
GETDATE() as nextCharge
--leave this empty, use GETDATE() to force it to be a datetime
into ##ChargeTable
from [RechargeTable] currentday
left join [RechargeTable] prevday
on DATEADD(d,1,prevday.Date) = currentday.Date
AND prevday.user = currentday.user
Now, we know when the user has charged. The charge column will be positive.
Select
user,
date
into ##uniquedates
from ##charge
where charge>0
Now that we have the dates, we need to go back to the first temp table and update it with the next dates. (not sure on the syntax on aliasing updates).
update ##ChargeTable up
set
nextCharge = (
select
date
from ##uniquedates
where up.user == user AND date > up.date
)
Now we can do some sub selects back on the table to get the data we need.
select
user,
(select
avg(voice)
from ##ChargeTable
where user = ct.user
and date>=ct.date
and date<=ct.nextCharge) as AvgVoice,
(select
avg(data)
from ##ChargeTable

and date>=ct.date
and date<=ct.nextCharge) as AvgData
from ##ChargeTable ct

d5820 | train | You consider to use a staging environment?
A staging environment (stage) is a nearly exact replica of a production environment for software testing. Staging environments are made to test codes, builds, and updates to ensure quality under a production-like environment before application deployment. The staging environment requires a copy of the same configurations of hardware, servers, databases, and caches. Everything in a staging environment should be as close a copy to the production environment as possible to ensure the software works correctly.
See the Font
To use it, i recommend you a application like Heroku, after configure, you can 'deploy' your app commiting in a branch (its not real time, but works for your case).

d5827 | train | As stated in the Monaca Backend API Reference Guide, Monaca backend requires a phonegap plugin thus the browser does not have these installed and therefore you will not be able to access those systems.
Ultimately, there is nothing you can do other than to test in the app, although if you use the Monaca Cloud IDE, you do gain a web interface to manage the backend. It is very useful.
Hope this helps! | unknown | |
d5828 | train | I will answer as if this is for real work, as you did not indicate explicitly schoolwork.
ThreadLocalRandom
Use ThreadLocalRandom to avoid any possible concurrency issues. There is no downside to using this class over Math.random. And this class has convenient methods for generating various types of numbers rather than just double.
java.time
Never use Calendar or Date. Those terrible date-time classes were supplanted years ago by the modern java.time classes defined in JSR 310.
Get today's date.
ZoneId z = ZoneId.of( "America/Montreal" ) ;
LocalDate today = LocalDate.now( z ) ;
Add random number of days within next 30 days.
int days = ThreadLocalRandom.current().nextInt( 1 , 31 ) ;
LocalDate localDate = today.plusDays( days ) ;
Days vary in length, such as 23, 24, 25, or other number of hours. So for your date in your zone, calculate maximum number of seconds.
ZonedDateTime start = localDate.atStartOfDay( z ) ;
ZonedDateTime stop = localDate.plusDays( 1 ).atStartOfDay( z ) ;
Duration d = Duration.between( start.toInstant() , stop.toInstant() ) ;
long seconds = d.toSeconds() ; // In Java 9 and later. For Java 8, call `Duration::getSeconds`.
That count of seconds becomes the maximum for our length of day. From this we pick a random number of seconds.
long secondsIntoDay = ThreadLocalRandom.current().nextInt( 0 , seconds ) ;
ZonedDateTime zdt = start.plusSeconds( secondsIntoDay ) ;
Determine a random duration from 1 to 60 minutes for the elapsed time of each event.
int minutes = ThreadLocalRandom.current().nextInt( 1 , 61 ) ; // At least one minute, and less than 61 minutes.
Duration duration = Duration.ofMinutes( minutes ) ;
Define your public class InterviewSlot with two member fields: a ZonedDateTime and a Duration.
A: Simple solution with date for your spezific case, including an example:
import java.util.Date;
import java.util.Random;
import org.apache.commons.lang3.time.DateUtils;
public class SimpleDateGenerator {
private static Random random = new Random();
public static Date getRandomDate(Date start, long timerangeSeconds) {
int randomTime = (int) Math.ceil(random.nextDouble() * timerangeSeconds);
return DateUtils.addSeconds((Date) start.clone(), randomTime);
}
public static void main(String[] args) {
Date now = new Date();
System.out.println(now);
for (int i = 0; i < 10; i++) {
System.out.println(getRandomDate(now, 30 * 24 * 60 * 60));
}
}
}
main gives following (example) output:

System.out.println("After sorting: \n");
//Using lamda
interviewSlotArrayList.forEach(element -> {
System.out.println(element);

//or Using method reference
interviewSlotArrayList.forEach(System.out::println);
}
public static InterviewSlot calculateInterviewSlot() {
//Getting time zone id and setting local time according to the time zone
ZoneId z = ZoneId.of("America/Montreal");
LocalDate today = LocalDate.now(z);
//Getting a random day between 1 and 31 and adding it to the current date
int days = ThreadLocalRandom.current().nextInt(1, 31);
LocalDate localDate = today.plusDays(days);
//Getting start and end time of the day as per time zone.End time is taken as next day start time(24 hr)
ZonedDateTime start = localDate.atStartOfDay(z);
ZonedDateTime stop = localDate.plusDays(1).atStartOfDay(z);
//Duration is taken which is the max duration for that time zone.
Duration duration = Duration.between(start.toInstant(), stop.toInstant());
long seconds = TimeUnit.SECONDS.convert(duration.toNanos(), TimeUnit.NANOSECONDS);
//Calculating random no of seconds keeping the computed seconds as max seconds in the day
long secondsIntoDay = ThreadLocalRandom.current().nextInt(0, Math.toIntExact(seconds));
ZonedDateTime zonedDateTime = start.plusSeconds(secondsIntoDay);
//Calculating random no of minutes for duration
int minutes = ThreadLocalRandom.current().nextInt(1, 61);
Duration durationMinutes = Duration.ofMinutes(minutes);
return new InterviewSlot(zonedDateTime, durationMinutes);
}
}
InterviewSlot.java :
public class InterviewSlot implements Comparable<InterviewSlot> {

d5829 | train | i think for now the safest option is to add appendonly yes in your redis config.
if you are using version 1.1 or greater one.
appendfsync always is slowest among them. if you are okay with that then sure you can use it. but if you care about your DB's performance use appendfsync everysec.
The append-only file is a fully-durable strategy for Redis. every time Redis receives a command that changes the dataset (e.g. SET) it will append it to the AOF. When you restart Redis it will re-play the AOF to rebuild the state.

d5831 | train | I can't explain why this fails as I am just inserting the content of the successful case into a container that simply performs the default vertical stacking (flex-direction: column).
The difference is that this new primary container has align-items: flex-start.
By experimentation I have discovered that removing the align-items property from the outer level container (#container) fixes the problem but I can't explain that either.
When you nest the .labelinput flex containers in the larger container (#container), then the .labelinput elements become flex items, in addition to flex containers.
Since the #container flex container is set to flex-direction: column, the main axis is vertical and the cross axis is horizontal1.
The align-items property works only along the cross axis. It's default setting is align-items: stretch2, which causes flex items to expand the full width of the container.
But when you override the default with align-items: flex-start, like in your code, you pack the two labelinput items to the start of the container, as illustrated in your problem image:
Because stretch is the default value for align-items, when you omit this property altogether, you get the behavior you want:
I understand that the outermost container (#container) is asked to layout two other containers (of class labelinput) so whatever property I set for align-items in the outermost container should apply to the inner containers as a whole, not change the layout of their internal items.
The outermost container is not changing the layout of the inner container's children. At least not directly.
The align-items: flex-start rule on the outermost container is applying directly to the inner containers. The internal items of the inner containers are just responding to the sizing adjustment of their parent.
Here's an illustration of align-items: flex-start impacting .labelinput (red borders added).
#container {
display: flex;
flex-direction: column;
justify-content: flex-start;
align-items: flex-start;
margin: 5px;
border: 1px solid grey;
}
.labelinput {
display: flex;
flex-flow: row;
margin: 1px;
border: 2px dashed red;
}
.labelinput > *:first-child {
flex-basis: 7em;
flex-grow: 0;
flex-shrink: 0;
}
.labelinput > *:nth-child(2) {
flex-grow: 1;
flex-shrink: 1;
border: 3px solid purple;
}
<div id='container'>
<div class='labelinput'>
<div>1st input</div>
<div>this is just a div</div>
</div>
<div class='labelinput'>
<div>2nd:</div>
<input type="text" name="foo" value="this is the input box" />
</div>
</div>
Moreover I can't explain why the layout is changed based on the element type when there's nothing in my CSS that differentiates between items of element div versus items of element input.
There may be no difference between div and input in your code, but there are intrinsic differences.
Unlike a div, an input element has a minimum width set by the browser (maybe to always allow for character entry).
You may be able to reduce the input width by applying min-width: 0 or overflow: hidden3.
Footnotes

d5833 | train | As of version 1.1.4, test sessions execute sequentially, within one test session. The reason for that is to be deterministic about what happens when, so testers can make reliable assumptions about the execution flow. This is important because tests can have dependencies between them and must execute in a specific order for them to succeed. To be sure, this is a bad practice, but it's sometimes necessary for practical reasons.
To execute tests in parallel, you must create two (or more) separate test sessions, so you must split your current session template in two. In the future, OpenTest will introduce an option that will allow one single test session to execute against multiple actors, but the default will still be executing the tests sequentially. | unknown | |

A: You could set the class instance as the DataContext of your userControl and use the default bind mechanism with a relative Path.
To support two way binding (class updates UI, UI updates class) the class should implement INotifyPropertyChanged (or have the specified properties defined as DependencyProperty).

d5836 | train | The first instance of the application should create a named pipe, subsequent instances of the application would fail to create the same named pipe and should instead attempt to open the named pipe for use. Once opened, the string (or really any data) can be transferred to the already running instance of the app. The named pipe can then be closed and the app could exit.
Alternatively, you could use .NET Remoting and register a well-known type that other instances of the application could activate, with behavior similar to what is described above.
Ultimately, a quick search on "IPC" or "Inter-Process Communication" may open up other alternatives. But I believe the named pipe approach is the cleanest and would be the easiest to implement/extend.
For "first-run" detection you can also create a named mutex, in case you opt for an IPC mechanism that doesn't exhibit a failure condition on multiple-runs (for example, using a database as a middle-man for data share). No two processed can "Create" a mutex with the same name, this is the same constraint as with Named pipes, as these names are managed by the Kernel (and thus span process, session, desktop and window station boundaries.) | unknown | |

d5838 | train | Changing the place of forall in the main lemma makes it much easier to prove. I wrote it as follow:
Lemma strong_induct_is_correct : forall (nP : nat->Prop),
strong_induct nP -> (forall n k, k <= n -> nP k).
(Also note that in the definition of strong_induct you used <= so it's better to use the same relation in the lemma as I did.)
So I could use the following lemma:
Lemma leq_implies_le_or_eq: forall m n : nat,
m <= S n -> m <= n \/ m = S n.
to prove the main lemma like this:
Proof.
intros nP [Hl Hr] n.
induction n as [|n' IHn].
- intros k Hk. inversion Hk. apply Hl.
- intros k Hk. apply leq_implies_le_or_eq in Hk.
destruct Hk as [Hkle | Hkeq].
+ apply IHn. apply Hkle.
+ rewrite Hkeq. apply Hr in IHn. apply IHn.
Qed.
This is much a simpler proof and also you can prove a prettier lemma using the lemma above.
Lemma strong_induct_is_correct_prettier : forall (nP : nat->Prop),
strong_induct nP -> (forall n, nP n).
Proof.
intros nP H n.
apply (strong_induct_is_correct nP H n n).

Note: Usually after using a destruct or induction tactic once, it is not very helpful to use one of them again. So I think using destruct n' after induction n would not bring you any further. | unknown | |

d5840 | train | i created an example of how to make it simple (in my opinion).
I merged the three states into one. this way i can get each one in more dynamic way. then i created on change handler that handles the changes and doing the all if statements (with less code).
each input is firing the change handler on change. and it sets the state according to the if statements.
this way we can create as many inputs as we want, we just need to pass the right arguments to the change handler and it will take care of the rest for us (and to make sure to include one more key value pair to the state)
this is the dummy data for Data:
const Data = { field1: "abc", field2: "efg" };
the state:
const [generalState, setGeneralState] = useState({
unsavedChanges: [],
customField1: "",
customField2: ""
});
the handler:
const changeTheState = (type, value, field, customField) => {
//setting the values to the state. so we can fetch the values for the inputs and for later use
setGeneralState((prev) => ({ ...prev, [type]: value }));
// i narrowed down the if statements. now its only two.
if (
value === Data[field] &&
generalState.unsavedChanges?.includes(customField)
) {
return setGeneralState((prev) => {
let filtered = prev.unsavedChanges.filter(
(item) => item !== customField
);
return { ...prev, unsavedChanges: filtered };
});
}
if (!generalState.unsavedChanges?.includes(customField)) {
setGeneralState((prev) => ({
...prev,
unsavedChanges: [...prev.unsavedChanges, customField]
}));
}
};
and the jsx:
<div className="App">
<input
value={generalState.customField1}
onChange={(e) => {
changeTheState(
"customField1",
e.target.value,
"field1",
"customField1"
);
}}
/>
<input
value={generalState.customField2}
onChange={(e) => {
changeTheState(
"customField2",
e.target.value,
"field2",
"customField2"
);
}}
/>
<h1>{generalState.unsavedChanges.length} # of unsaved changes.</h1>
<button disabled={generalState.unsavedChanges.length > 0 ? false : true}>
Submit
</button>
</div>
here is the example : codesandbox example

d5845 | train | Most AB testing you hear about is referring to client-side tests powered by injecting JS in the browser. Testing in a Java app requires a different approach.
You can use a free, open-source tool such as Planout. This serves as a basic traffic splitter and uses a deterministic hashing algorithm so that you get consistent variations as long as you keep using the same user ID.
If you need more robust functionality, you may need to go for a commercial package. For in-app testing (mobile, web, backend), these usually take 1 of 2 forms:
*
*API approach: your app can send a request to the vendor-managed server asking for a variation for the current user. The downside here is the performance hit of waiting for a response every time you need the user's variation.
*SDK: vendor-provided SDK you implement in your Java code base that uses a deterministic hash to determine the variation for the user. The SDK will need retrieve some kind of data file with experiment status, traffic allocation, etc from a server prior to running the experiment (and on some update frequency), but then lets you determine variations in memory (no blocking network calls). Tracking calls can be sent async.
A commercial package will give you a few benefits over a free solution, like a user-friendly web portal to manage experiments, a statistical calculator, QA tools, feature flags, user permissions, ongoing updates and support, etc.

d5847 | train | $targetsvr.Roles.Members is a legal expression that results in a collection of all members of all roles (it's equivalent to $targetsvr.Roles | Foreach { $_.Members }). But this collection is synthesized by PowerShell, not an actual member of something, so you can't modify it. You want $targetsvr.Roles["Administrators"].Members instead. And you explicitly need to update the role before the server will see the changes. And you want to give the cmdlet a better name as well. If I may:

d5848 | train | First as stated in the comments, there is no cost to using full columns:
=SUMIF(D:D,"Restaurant",C:C)
Which now it does not matter how large it gets.
excel
But if one wants to limit it using other cells, I would use INDEX, instead of INDIRECT as INDIRECT is volatile(This only works in Excel):
=SUMIF(INDEX(D:D,T1):INDEX(D:D,T2),"Restaurant",INDEX(C:C,T1):INDEX(C:C,T2))
Where Cell T1 holds the start row and T2 holds the end row.
A: you could use simple QUERY like:
=QUERY({C13:D}, "select Col2, sum(Col1)
where Col2 matches 'Restaurant'
group by Col2
label sum(Col1)''", 0)
or for the whole group:
=QUERY({C13:D}, "select Col2, sum(Col1)
where Col2 is not null

d5851 | train | Type inference is a feature of some statically-typed languages. It is done by the compiler to assign types to entities that otherwise lack any type annotations. The compiler effectively just 'fills in' the static type information on behalf of the programmer.
Type inference tends to work more poorly in languages with many implicit coercions and ambiguities, so most type inferenced languages are functional languages with little in the way of coercions, overloading, etc.
Type inference is part of the language specification, for the example the F# spec goes into great detail about the type inference algorithm and rules, as this effectively determines 'what is a legal program'.
Though some (most?) languages support some limited forms of type inference (e.g. 'var' in C#), for the most part people use 'type inference' to refer to languages where the vast majority of types are inferred rather than explicit (e.g. in F#, function and method signatures, in addition to local variables, are typically inferred; contrast to C# where 'var' allows inference of local variables but method declarations require full type information).
A: A type inferencer determines what type a variable is from the context. It relies on strong typing to do so. For example, functional languages are very strongly, statically typed but completely rely on type inference.
C# and VB.Net are other examples of statically typed languages with type inference (they provide it to make generics usable, and it is required for queries in LINQ, specifically to support projections).
Dynamic languages do not infer type, it is discovered at runtime.
A: Type inferencing is a bit of a compromise found in some static languages. You can declare variables without specifying the type, provided that the type can be inferred at compile time. It doesn't offer the flexibility of latent typing, but you do get type safety and you don't have to write as much.
See the Wikipedia article.
A: A type inferencer is anything which deduces types statically, using a type inference algorithm. As such, it is not just a feature of static languages.
You may build a static analysis tool for dynamic languages, or those with unsafe or implicit type conversions, and type inference will be a major part of its job. However, type inference for languages with unsafe or dynamic type systems, or which include implicit conversions, can not be used to prove the type safety of a program in the general case.
As such type inference is used:
*
*to avoid type annotations in static languages,
*in optimizing compilers for dynamic languages (ie for Scheme, Self and Python),
*In bug checking tools, compilers and security analysis for dynamic languages. | unknown | |

d5853 | train | What you'll probably want to consider, is using Paperclip (or another similar gem) to store the data on S3. Within your application, you can then locate/compute the data you'll need to display through your Paperclip-based model, then have Paperclip retrieve and load the data you need.
The nice thing about such a solution is that it's completely transparent for you (as a user AND as a developer): you're just working with your objects, and they get stored/retrieved form S3 as needed.
A: Both Heroku and Engineyard (probably the two largest cloud providers for rails) use S3 as the backend, so using these providers could be great.
Heroku tends to be more 'out-of-the-box' so I think EngineYard with CLI(Command Line) access would be better suited to your needs.
More info on the two at
Heroku vs EngineYard: which one is more worth the money? and
http://mikemainguy.blogspot.com/2011/08/heroku-is-bus-engineyard-is-car.html and
http://www.cuberick.com/2010/04/engine-yard-vs-heroku-getting-started.html has more on setup / cost.
A: This is very possible. Use the fog gem.
I have to not recommend you use carrierwave or paperclip for your specific needs here. They're good when you are uploading the data initially, but in your case you're accessing existing data. Just use fog to connect to s3 directly. | unknown | |
d5854 | train | I try to avoid right join because it's needlessly confusing.
Here's an example left join approach:
select e.employee_id
, m.month
, a.project
, sum(a.worked)
from (
select distinct employee_id
from TableA
) e
, MonthsTable m
left join
TableA a
on a.employee_id = m.employee_id
and month(a.date_wrk) = m.month
group by
e.employee_id
, m.month
, a.project
The cross join creates a matrix of each employee and each month. For each employee-month combination in the matrix, it optionally looks up the project hours.
A: Ok I did it basing on Andomar suggestion - but as Access is not fond of sub-queries and cross join I created additional table based on :
select distinct employee_id,months.month
from TableA,months
which give me a cross join table which then I linked to tableA.

d5856 | train | The Gang of Four's main contribution to Design Patterns is really giving names to some commonly-used patterns to assist communication of design intent. It's so much easier to write
// this is an observer
than a big ol' block of comments that no one will read. And if people shared the jargon, developers can communicate more effectively.
The Observer pattern has been around long before OO programming. Most often it was referred to using the term "callback", often implemented with function pointers in various languages, or perhaps even a flag that was used to indicate which function/procedure/subroutine should be called. This represented one of the earliest forms of abstract communication between modules. I've even seen similar approaches taken in assembler languages - storing a callback address and using it to indirectly notify that "something happened".
A big thing to remember... the implementations that the Gang of Four show in the Design Patterns book are not "absolute" - they're there to demonstrate an approach. You can just as easily implement the Observer pattern with a function pointer as you can with an abstract class, interface, or C# delegate.
(I teach a Design Patterns course at Johns Hopkins, btw ;) )
A: What The Gang of Four did wasn't invent patterns, they observed and researched the software field at the time in order to catalog the solutions to the common problems faced by developers.
As for who initially invented it your guess is as good as mine I suppose. Although I'll be interested if anyone do know who invented it. In my opinion it's like asking who invented fire...
ConcreteSubject refers to the implementation of the Subject interface. And it's not a variation it's simply necessary to have a interface to facilitate the pattern. (or a super class but an interface is much more better). | unknown | |

d5858 | train | Maybe you can use Expectation-maximization algorithm. Your points would be (value, position). In your example, this would be something like:
With the E-M algorithm, the result would be something like (by hand):
This is the desired output, so you can consider using this, and if it really works in all your scenarios. An annotation, you must assign previously the number of clusters you want, but I think it's not a problem for you, as you have set out your question.
Let me know if this worked ;)
Edit:
See this picture, is what you talked about. With k-means you should control the delta value, this is, how the position increment, to have its value to the same scale that value. But with E-M this doesn't matter.
Edit 2:
Ok I was not correct, you need to control the delta value. It is not the same if you increment position by 1 or by 3: (two clusters)
Thus, as you said, this algorithm could decide to cluster points that are not neighbours if their position is far but their value is close. You need to guarantee this not to happen, with a high increment of delta. I think that with a increment of 2 * (max - min) values of your sequence this wouldn't happen.
Now, your points would have the form (value, delta * position). | unknown | |
d5859 | train | Not sure what caused the error, but running Docpad in an elevated command prompt solved the problem for me. I'm working on Windows 10. (I bet this issue is Windows related.)
To open a cmd with admin privileges, hit menu start and type cmd. Then hit ctrl+shift+enter or hit the right mouse button and select 'run as administrator'. The solution works in a Git Bash terminal with extra privileges, as well.
Edit: Today it broke again :/ (to the point that I question whether it did work yesterday...) The quest for an answer has started again...
Edit 2: The error is caused by docpad-plugin-gulp (or its dependencies) for sure; running the Gulp tasks directly works fine.
However, I found a setting in docpad-plugin-gulp called background. Setting this to true will run Gulp in the background. More important is that it removes the experienced errors altogether. This leads me to suspect the issue is caused by rule 64-67 of the plugin (out/gulp.plugin.js) or the functions it calls there:
this.safeps.spawn(command, {
cwd: rootPath,
output: true
}, next);
I hope people more knowledgeable of this topic can confirm my suspicions and/or fix the plugin. For now, updating your docpad.coffee like below should bypass the errors.
docpadConfig = {
# Other docpad settings
plugins:
gulp:
background: true

d5862 | train | I think what you are asking is if you can separate parts of an HTML page into smaller pages, so you can separate concerns.
In PHP this can be accomplished by referencing other files by a require() or include(). But I still don't believe this really answers your question. ASP.NET MVC allows you to render partial views within a webpage through `RenderPartial() but you didn't mention anything about using this.
You can find more at http://www.asp.net/mvc/videos/mvc-2/how-do-i/how-do-i-work-with-data-in-aspnet-mvc-partial-views
A: If you want to divide a single webpage into multiple hmtl files you can do it by inserting frames. This is an old way of programming and you don't really see it these days but its efficient at doing what you are asking.
A: Yes, this is highly recommended. You are trying to apply the DRY principle (see: http://en.wikipedia.org/wiki/Don't_repeat_yourself). It's an excellent idea to apply this to your HTML. You can achieve this using require, require_once, include, and include_once in PHP. If you want to get a bit fancier, take a look at templating systems like Smarty (see: http://www.smarty.net/) | unknown | |

Check http://mywiki.wooledge.org/BashFAQ for various subjects
A: For the examples given, I prefer cut. But for the general problem expressed by the question, the answers above have minor short-comings. For instance, when you don't know how many spaces are between the words (cut), or whether they start with a space or not (cut,sed), or cannot be easily used in a pipeline (shell for-loop). Here's a perl example that is fast, efficient, and not too hard to remember:
| perl -pe 's/^\s*(\S+\s+){2}//'
Perl's -p operates like sed's. That is, it gobbles input one line at a time, like -n, and after dong work, prints the line again. The -e starts the command-line-based script. The script is simply a one-line substitute s/// expression; substitute matching regular expressions on the left hand side with the string on the right-hand side. In this case, the right-hand side is empty, so we're just cutting out the expression found on the left-hand side.
The regular expression, particular to Perl (and all PLRE derivatives, like those in Python and Ruby and Javascript), uses \s to match whitespace, and \S to match non-whitespace. So the combination of \S+\s+ matches a word followed by its whitespace. We group that sub-expression together with (...) and then tell sed to match exactly 2 of those in a row with the {m,n} expression, where n is optional and m is 2. The leading \s* means trim leading whitespace. | unknown | |
d5864 | train | There are essentially two ways to approach this (that I can think of ATM):
Note: I would rename cFunctor and bFunctor to simply Functor in both cases. They are nested inside respective classes and thus such prefix makes little sense.
Type erased
Example of type erasure is std::function.
class A {
public:
int x;
std::vector<std::function<void(void)>> functors;
A() : functors { B::bFunctor(), C::cFunctor() }
{ }
};
If you need the functors to have more advanced behaviour, Boost.TypeErasure any might help.
Polymorphic
*
*Create an abstract functor type.
*Make B::bFunctor and C::cFunctor inherit from it.
*Store vector of that abstract functor type smart pointers.
struct AbstractFunctor {
virtual void operator()() const = 0;
};
class B {
public:
struct Functor : public AbstractFunctor {
void operator()() const {
//some code
}
};
};
class A {
public:
int x;
std::vector<std::unique_ptr<AbstractFunctor>> functors;
A() {
// this could most probably be shortened with make_unique
functors.emplace_back(std::unique_ptr<AbstractFunctor>(new B::Functor()));
functors.emplace_back(std::unique_ptr<AbstractFunctor>(new C::Functor()));
}

d5867 | train | It doesn't print reversed, nl is built reversed:
while not l.IsEmpty:
nl = Node(l.value,nl)
l = l.tail
each new nl is the tail of the next one. So 1 is the tail for 2, and so on.
A: Think about what is happening in the first while loop. It builds a new list in reverse. We start with Empty. Then each iteration:
new_list = Node(l.current_value, Node(l.previous_value))
Where previous_value is the value encountered first while iterating through the original list. So, this could be expanded to:
Node(l.last_value, Node(l.second_to_last, Node(...Node(l.first_value, Empty)...)))
A: It builds a forwards list
l = Node(1,Node(2,Node(3,Node(4,Empty))))
Then builds a backwards list from that forwards list
nl = Empty
while not l.IsEmpty:
nl = Node(l.value,nl)
l = l.tail
Then prints that list out in order, which is the reverse of the first list.
This is a pretty convoluted way of doing things. Better would be something recursive, like:

if curr.isEmpty:

d5873 | train | You can use aggregate
df_short = df.groupby(df.index.floor('D')).agg({'Distance': min, 'Value': max})
If you want the kept Value column is the same with minimum of Distance column:
df_short = df.loc[df.groupby(df.index.floor('D'))['Distance'].idxmin(), :]
A: Make a datetime Index:
df.DATE = pd.to_datetime(df.DATE) # If not already datetime.
df.set_index('DATE', inplace=True)
Resample and find the min Distance's location:
df.loc[df.resample('D')['Distance'].idxmin()]

d5878 | train | Not an answer (yet?) to the real problem, only to "is it normal", but also much too long for comments.
It is possible for one SSL/TLS server to have more than one certificate, and provide different ones on connection requests, although it would be odd to so for the same domainname; this is more common on servers that support multiple domains -- either for different parts or services of one entity, or a CDN or frontend like Cloudflare or Fastly(!) that handles connections for multiple entities. However, in the specific case of www.google.com that is not a single server but hundreds or thousands, all over the world, and it is quite possible that different servers have different certificates, either intentionally (perhaps for testing) or because they are making a change which does not happen instantly everywhere.
According to my notes recently www.google.com as accessed from my location was using certs under GTS CA 1O1 with this intermediate cert under GlobalSign Root CA - R2 as shown in your first image. Note that intermediate cert expires in 6 months, as does the root it is under, which is a good reason to stop using it. (https://crt.sh/?caid=10 does show two 'cross' certs for R2 under GlobalSign Root CA (see below) with longer expiration, but they are both revoked.)
As of today I get a cert under GTS CA 1C3 under GTS Root R1 -- so far like your second figure -- but then crossed under GlobalSign Root CA WITHOUT R1. Specifically I get this intermediate cert for GTS CA 1C3 and this cross cert for GTS Root R1, which are valid until 2027 and 2028 and appear here on the GTS website as GTS CA 1C3 and GTS Root R1 Cross respectively. And this cert for that GlobalSign root -- which in effect is R1, since the other currently known GlobalSign roots are R2-6, but is not named R1 -- has been in at least Java and Mozilla/Firefox truststores for long time; I can't easily check history on others. crt.sh doesn't know of ANY cert named with R1. I'd note that Firefox does have in its truststore a root cert for GTS Root R1 (and also R2-R4) which means it could shorten the chain, but doesn't; AFAICS no Java has any of these GTS roots.
Moreover the leaf certs I get have both CommonName and SubjectAltName www.google.com NOT *.google.com. This pretty much confirms you are getting a different server than I am.
It might help if you can extract the "GlobalSign R1" cert you apparently have in some truststore, and post it to be looked at or searched for, and the rest of the chain which you can get with keytool -printcert -rfc -sslserver www.google.com and/or if you can identify which google address(es?) you are getting this cert chain from so others (like me) can try it -- although even one address might anycast to multiple physical servers.
A: You can refer to Google's PKI Repository which lists 5 CAs.
As per the FAQ, they actually list 36 different CAs in the roots.pem file (as of 28th April, 2022).
Ideally you will need to add all those CAs to your trust store to cover all bases. | unknown | |

d5882 | train | A better title would be "WooCommerce up-sells as checkboxes".
A lot of research and several strategies to tackle this problem lead me to a solution which I thought was not even possible in the beginning.
The solution is now exactly what I wanted. A non-JavaScript, no-template-override, but a simple and pure addition to functions.php. It works for simple and variable products (and probably with grouped and external products too).
It misses some nice features still. It won't work yet if an up-sell is a variable product. Quantity selection and limiting up-sells per item or order would be nice additions too. Based on the code below adding those features should not be a big deal anymore.
// create the checkbox form fields and add them before the cart button
add_action( 'woocommerce_before_add_to_cart_button', 'action_woocommerce_before_add_to_cart_form', 10, 0 );
function action_woocommerce_before_add_to_cart_form(){
global $woocommerce, $product;
// get the product up-sells
$upsells = $product->get_upsells();
// store the number of up-sells and pass it on to the add-to-cart hook
?>
<input type="hidden" name="upsells_size" value="<?php echo(sizeof($upsells)); ?>">
<div id="wb-upsell-div">
<?php
// iterate through all upsells and add an input field for each
$i = 1;
foreach( $upsells as $value ){
$product_id = $value;
?>
<input id="wb-upsell-checkboxes" type="checkbox" name="upsell_<?php echo($i) ?>" value="<?php echo($product_id); ?>"><?php echo( '<a href="' . esc_url( get_permalink( $product_id )) . '" target="_blank">' . get_the_title( $product_id ) . "</a>". " ($" . get_post_meta( $product_id, '_regular_price', true) . ")"); ?><br>
<?php
$i++;
}
?>
</div>
<?php
}
// function to add all up-sells, where the checkbox have been checked, to the cart
add_action('woocommerce_add_to_cart', 'custom_add_to_cart', 10, 3);
function custom_add_to_cart() {
global $woocommerce;
// get the number of up-sells to iterate through
$upsell_size = $_POST['upsells_size'];
// iterate through up-sell fields
for ($i=1; $i<=$upsell_size; $i++){
// get the product id of the up-sell
$product_id = $_POST['upsell_' . $i];
$found = false;
//check if product already in cart
if ( sizeof( WC()->cart->get_cart() ) > 0 ) {
foreach ( WC()->cart->get_cart() as $cart_item_key => $values ) {
$_product = $values['data'];
if ( $_product->id == $product_id )
$found = true;
}
// if product not found, add it
if ( ! $found )
WC()->cart->add_to_cart( $product_id );
} else {
// if no products in cart, add it
WC()->cart->add_to_cart( $product_id );
}
}
}
And here is the CSS for formatting the <div>and the checkboxes. It goes into the style.css file:
#wb-upsell-div {
margin-top: 10px;
margin-bottom: 20px;
}
#wb-upsell-checkboxes{
}
A: So there's an actual answer to this question, you can add whatever you want inside the add to cart <form> using hooks. For example:
add_action( 'woocommerce_before_add_to_cart_button', 'so_34115452_add_input' );
function so_34115452_add_input(){
echo '<input type="checkbox" name="something"/>' . __( 'Some Checkbox', 'text-domain' );

If the element type is an array type and the corresponding ElementValue is not an ElementValueArrayInitializer, then an array value whose sole element is the value represented by the ElementValue is associated with the element. Otherwise, if the corresponding ElementValue is an ElementValueArrayInitializer, then the array value represented by the ElementValueArrayInitializer is associated with the element.
With a comment clarifying the above stating:
In other words, it is permissible to omit the curly braces when a single-element array is to be associated with an array-valued annotation type element.
Because Scala has no equivalent array initializer syntax, you must use Array(elems).

d5895 | train | The real "unexpected" behavior is that setting the flag makes the heap executable as well as the stack. The flag is intended for use with executables that generate stack-based thunks (such as gcc when you take the address of a nested function) and shouldn't really affect the heap. But Linux implements this by globally making ALL readable pages executable.
If you want finer-grained control, you could instead use the mprotect system call to control executable permissions on a per-page basis -- Add code like:
uintptr_t pagesize = sysconf(_SC_PAGE_SIZE);
#define PAGE_START(P) ((uintptr_t)(P) & ~(pagesize-1))
#define PAGE_END(P) (((uintptr_t)(P) + pagesize - 1) & ~(pagesize-1))
mprotect((void *)PAGE_START(shellcode), PAGE_END(shellcode+67) - PAGE_START(shellcode),
PROT_READ|PROT_WRITE|PROT_EXEC);
A:
Is this expected behavior?
Looking at the Linux kernel code, I think that the kernel-internal name for this flag is "read implies exec". So yes, I think that it's expected.
It seems like it is bad idea to require the stack to be executable in order to make the heap executable, since there are many more legitimate use cases of the latter than the former.
Why would you need the complete heap to be executable? If you really need to dynamically generate machine code and run it or so, you can explicitly allocate executable memory using the mmap syscall.
what is the rationale?
I think that the idea is that this flag can be used for legacy programs that expect that everything that's readable is also executable. Those programs might try to run stuff on the stack and they might try to run stuff on the heap, so it's all permitted. | unknown | |

d5897 | train | It means that if n, the argument passed to the function, is falsey, 2000 will be assigned to it.
Here, it's probably to allow callers to have the option of either passing an argument, or to not pass any at all and use 2000 as a default:
function delay(n){
n = n || 2000
console.log(n);
}
delay();

However, as mentioned in the other answers, using ast.literal_eval would be a more concise solution.

# A string, so return str
return str
print(get_type("1")) # <class 'int'>
print(get_type("1.2354")) # <class 'float'>
print(get_type("True")) # <class 'bool'>
print(get_type("abcd")) # <class 'str'>
A: Input will always return a string. You need to evaluate the string to get some Python value:
>>> type(eval(raw_input()))
23423
<type 'int'>
>>> type(eval(raw_input()))
"asdas"
<type 'str'>
>>> type(eval(raw_input()))
1.09
<type 'float'>
>>> type(eval(raw_input()))
True
<type 'bool'>
If you want safety (here user can execute arbitrary code), you should use ast.literal_eval:
>>> import ast
>>> type(ast.literal_eval(raw_input()))
342
<type 'int'>
>>> type(ast.literal_eval(raw_input()))
"asd"
<type 'str'>
A: The problem here is that any input is taken a 'string'. So we need to treat 'string' as a special case, and keep it separate from everything else.
x = input("Enter something: ")
try:
if type(eval(x)) == float:
print(x, " is floating point number")
elif type(eval(x)) == int:
print(x, " is interger number")
elif type(eval(x)) == bool:
print(x, " is a boolean")
except:
print("That is a string")
Here the input is first evaluated. If it's anything other than a string, the eval function shall show the type. If it's a string, it is considered as an "error", and the error message is given as "That is a string". | unknown | |
