stream | Prototype Hadoop streaming-like SciDB API

Im trying to reproduce pretty simple snippet from https://laravel.com/docs/8.x/eloquent#streaming-results-lazily

I'm trying to understand how the "fetch" phase of the CPU pipeline interacts with memory.

Let's say I have these instructions:

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?

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) :

I have an AWS ubuntu instance with the following network interfaces:

ens5, ip: 172.XX.XX.XX

A5TAP, ip:192.168.233.1 (VPN)

How do I udp port forward port 10000-10200 to 192.168.233.52:10000-10200? I tried a the obvious commands below for a single port 10009, but it is not working:

I am trying to run a test case which basically copies a file from my machine to a mock server running in docker. The same test works fine on Mac and Ubuntu. But on Windows it's getting failed with the following error:-

I have a Set of objects that consists of name and value. My requirement is to create a new Set by grouping the Set based on objects that have the same value and concate the property name into a single string separated by ",".

Example:

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:

1. 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.

2. In the else block the flow is redirected towards the call method inside the TailCall class which will return the same object.

3. 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,

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!
