QUESTION
I am new to rust and I was reading up on using futures
and async / await
in rust, and built a simple tcp server using it. I then decided to write a quick benchmark, by sending requests to the server at a constant rate, but I am having some strange issues.
The below code should send a request every 0.001 seconds, and it does, except the program reports strange run times. This is the output:
...ANSWER
Answered 2021-Jun-15 at 20:06You are not measuring the elapsed time correctly:
total_send_time
measures the duration of thespawn()
call, but as the actual task is executed asynchronously,start_in.elapsed()
does not give you any information about how much time the task actually takes.The
ran in
time, as measured bystart.elapsed()
is also not useful at all. As you are using blocking sleep operation, you are just measuring how much time your app has spent in thestd::thread::sleep()
Last but not least, your
time_to_sleep
calculation is completely incorrect, because of the issue mentioned in point 1.
QUESTION
I am querying a database for an item using R2DBC and Spring Integration. I want to extend the transaction boundary a bit to include a handler - if the handler fails I want to roll back the database operation. But I'm having difficulty even establishing transactionality explicitly in my integration flow. The flow is defined as
...ANSWER
Answered 2021-Jun-15 at 18:32Well, it's indeed not possible that declarative way since we don't have hook for injecting to the reactive type in the middle on that level.
Try to look into a TransactionalOperator
and its usage from the Java DSL's fluxTransform()

QUESTION
How do I produce an animation that simulates the burning effect of fire consuming an UIView
from top to bottom in Swift?
I found Fireworks, an app that allows users to tweak and try out different settings of CAEmitterLayer
with instant results. The effects are great for applying to a whole screen but how would I use it for my purpose - where the UIView
must disappear as the fire consumes it from one end to the other?
Is there some tutorial on consuming UIView
s with fire using the particle emitter anywhere? I know that I’m supposed to show some code but anything I put here would be irrelevant. I’ve also exhausted my search engine looking for something similar. That’s how I found the Fireworks app actually.
This seems to be a use case that shouldn't be uncommon.
...ANSWER
Answered 2021-Jun-14 at 14:24I was once in your shoe before and came across this Open source library called particle animations.
I would NOT recommend using the library itself since it's deprecated. But I would recommend referring to its source code to get an idea of how to use CAEmitterLayer and CAEmitterCell
to make the looks of a Fire!
As you could see from its readme, it has direct examples of Fire. It also states that even Apple and Facebook uses CAEmitterLayer and CAEmitterCell
to produce the effect of a fire.
Feel free to ask for more questions.
QUESTION
SpringBoot v2.5.1
There is an endpoint requesting a long running process result and it is created somehow
(for simplicity it is Mono.fromCallable( ... long running ... )
.
Client make a request and triggers the publisher to do the work, but after several seconds client aborts the request (i.e. connection is lost). And the process still continues to utilize resources for computation of a result to throw away.
What is a mechanism of notifying Project Reactor's event loop about unnecessary work in progress that should be cancelled?
...ANSWER
Answered 2021-Jun-15 at 09:06fromCallable
doesn't shield you from blocking computation inside the Callable
, which your example demonstrates.
The primary mean of cancellation in Reactive Streams is the cancel()
signal propagated from downstream via the Subscription
.
Even with that, the fundamental requirement of avoiding blocking code inside reactive code still holds, because if the operators are simple enough (ie. synchronous), a blocking step could even prevent the propagation of the cancel()
signal...
A way to adapt non-reactive code while still getting notified about cancellation is Mono.create
: it exposes a MonoSink
(via a Consumer
) which can be used to push elements to downstream, and at the same time it has a onCancel
handler.
You would need to rewrite your code to eg. check an AtomicBoolean
on each iteration of the loop, and have that AtomicBoolean flipped in the sink's onCancel
handler:

QUESTION
On Mac OS X 10.7.5 on which perl-5.12.3
is installed, I needed to use the utf8::all
module so I have manually installed utf8-all-0.024 (Note the minimum perl version of v5.10.0
on its CPAN page) The make test
has failed but I've still installed it to see if it would work. It didn't work so I've decided to uninstall it. I've tried 2 methods given at perl.com the first method didn't work as it required perl-5.14.2
The second method gave this message:
ANSWER
Answered 2021-Jun-14 at 18:28You've made a mess of things by incorrectly installing the module. Specifically, you didn't install the dependencies.
Ideally, you should use the package manager that provided perl
itself. But they don't provide every module. So you'd use the non-package manager approach:

Stackblitz for this problem. That's the closest I could get.
I'm using Material Drag & Drop. The result I'm looking for is to clone an item from a LIST and put into another list, which is visually an AREA, but that's the "catch", keeping the dropped "coordinates" (x,y) on that area.
That's my HTML code:
...ANSWER
Answered 2021-Apr-30 at 21:40I believe this comes close to what you were after.
Two adjustments:
changed widget positioning to
absolute
-- transforming withposition: relative
was repositioning the widgets in an inconsistent manner.had to adjust the
translate
-- I'm no expert with this library but it looks like the nativeElement transform properties are set relative to the position of the drawer option the user selects (the NOTE vs COLUMN options in your example). If you add more options you might have to adjust x,y for each depending on where the option is in the drawer space.
Hope this helps and cheers!
QUESTION
When I'm doing activity from a user in a project, I get the instant location and save it with firebase and firestore. But when I call back the query, I get everything I saved in the list. I just want it to come as an index index. For example 1-"kosum1". How can I do that?
...ANSWER
Answered 2021-Jun-13 at 10:59You can convert the List
to a Map
of its index to the list value using the List.asMap() method.
The map uses the indices of this list as keys and the corresponding objects as values.
Change this part of your code:

I want to cut down the size of my metadata struct for my own heap allocator. One field in my struct holds a pointer to the next instance of the struct:
...ANSWER
Answered 2021-Mar-06 at 20:56If the memory pool was allocated as a single object (like result of a single malloc() or a global array) then pointer arithmetics can be safely used.
QUESTION
my users have a collection in their userData
document called notifications
. I want to listen to these in realtime so you can see notifications instantly (like any social media app, facebook instagram etc).
In my app.js, I currently have this useEffect:
...ANSWER
Answered 2021-Jun-11 at 20:42The main issue is that useEffect
hook callbacks can't be async
functions as these implicitly return a Promise which would, by design, be interpreted as an useEffect
hook cleanup function. This won't work.
After looking at your code for a bit it looks like getting and setting the data
state is independent of the firebase subscription. You can minify just the asynchronous logic into an async
function to get and set the user data and invoke that, and access the firebase collection as per normal.
Use a React ref to hold on to the unsubscribe
callback.
I think the following implementation should get you very close to what you are looking for. (Disclaimer: I've not tested this code but I think it should work)
