kandi X-RAY | Stream Summary
This is a Swift microframework providing a lazy Stream type with generic implementations of ==/!= where T: Equatable. Streams are lazily-populated as well as lazily-evaluated, making them convenient for procrastinating tasks you don’t want to do yet, like performing an expensive computation in successive stages. You can construct Streams with SequenceTypes, use them as SequenceTypes, and map and fold to your heart’s content.

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_timemeasures 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 intime, 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_sleepcalculation is completely incorrect, because of the issue mentioned in point 1.

QUESTION
I'm trying to understand how the "fetch" phase of the CPU pipeline interacts with memory.
Let's say I have these instructions:
...ANSWER
Answered 2021-Jun-15 at 16:34It varies between implementations, but generally, this is managed by the cache coherency protocol of the multiprocessor. In simplest terms, what happens is that when CPU1 writes to a memory location, that location will be invalidated in every other cache in the system. So that write will invalidate the line in CPU2's instruction cache as well as any (partially) decoded instructions in CPU2's uop cache (if it has such a thing). So when CPU2 goes to fetch/execute the next instruction, all those caches will miss and it will stall while things are refetched. Depending on the cache coherency protocol, that may involve waiting for the write to get to memory, or may fetch the modified data directly from CPU1's dcache, or things might go via some shared cache.

I am using the following code to retrieve the html code from a url. It is working fine for a url as:
- https://trends.google.com/trends/?geo=US However, not working for the following one, returning an error as
"The remote server returned an error: (429) unknown.'"
What could be the error or how to get more info about the error?
...ANSWER
Answered 2021-Apr-13 at 19:44It's no longer possible to get the source code of google services without an API because specifically the trends service makes many calls when you visit only trends.google.es/trends/explore?q=test hence the error 429.
Do not waste your time digging in proxies, browser emulation or bots none will work. The best way is to use Google API for c# .

QUESTION
I am writing a program in C language using gtk3 library. I want it to be able to receive a h264 video stream from a certain IP address (localhost) and UDP/RTP PORT (5000).
In order to do it, I am using gstreamer to both stream and receive the video.
I managed to stream the video using the following pipeline :
send.sh :
gst-launch-1.0 filesrc location=sample-mp4-file.mp4 ! decodebin ! x264enc ! 'video/x-h264, stream-format=(string)byte-stream' ! h264parse ! rtph264p
I managed to display the video in a new window using the following pipeline :
receive.sh :
gst-launch-1.0 udpsrc port=5000 caps="application/x-rtp,encoding-name=H264" ! rtph264depay ! decodebin ! videoconvert ! autovideosink
At this point, everything works fine. But now I want to receive the stream and display it inside my C/GTK program. I am using the following code (found on internet and adapted to make it compile) :

QUESTION
I am trying to lambda Java8 lambda expressions, Wherein I came across this example. I am unable to understand the program flow,
The the below example when the factorialTailRec(1, 5).invoke() statement is called the program flow is as shown below:
The program first goes to the factorialTailRec method and once and checks if the number value is equal to 1. In the first iteration, it's not so it goes to the else part.
In the else block the flow is redirected towards the call method inside the TailCall class which will return the same object.
Now the invoke method is called and then the Stream object tries to iterate through the result. I am not getting how the factorialTailRec is called again? They say its because of the below statement,

QUESTION
I am working on a Instagram face filter/effect with SparkAR. It is successfully uploaded, approved and works just fine when across many devices when I try the effect in the Instagram app. I can select the effect when creating a Story however – I cannot when doing a Live stream. The effect symbol doesn’t show up nor can I select it when searching for the effect, while all the other effects are still there.
One user reported that she was able to select the effect during Live on her Android device. But at least on iOS devices it seems to be impossible to find or select the effect.
Are there any differences between Live and Non-Live effects? Or between iOS and Android effects? Has anyone had the same problem before? How can I make sure that my effect is available for Live streaming?
Thank you for any hints!
...ANSWER
Answered 2021-Jun-15 at 08:37Turns out, that the use of audio inside the filter caused it to not appear in Live mode. I removed all audio files and playback controllers and enabled the microphone. It now works.
