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.

New, TLSv1/SSLv3, Cipher is ECDHE-RSA-AES256-GCM-SHA384
You're apparently using OpenSSL 1.0.2, where that's a basically useless relic. Back in the days when OpenSSL supported SSLv2 (mostly until 2010, although almost no one used it much after 2000), the ciphersuite values used for SSLv3 and up (including all TLS, but before 2014 OpenSSL didn't implement higher than TLS1.0) were structured differently than those used for SSLv2, so it was important to qualify the ciphersuite by the 'universe' it existed in. It has almost nothing to do with the protocol version actually used, which appears later in the session-param decode:

QUESTION
I am pretty new to using openCV and this might be a silly question.
I will talk in reference to the picture above. So my problem statement is to draw bounding boxes around all the text elements. Conveniently I can get that information from the json file of the image. So I can get x, y, w and h from json and use cv2.rectangle(img1, (x, y), (x + w, y + h), (255, 255, 255), 2)
The issues is in the json file, for rotated text, it just provides the rotation angle and not the co-ordinates for the rotated rectangle. For example from the image above, for 'yourwebsite.com', x, y, w and h is given and rotation is -90 degrees. I did some basic w, h = h, w to get the bounding box for that. But what should I do when the degrees is like 60 ro 80. Is there any function or method to get the coordinates of rotated bounding boxes?
In this case the flash sale is tilted at an angle of -22 degrees. But the x, y, w and h is provided for the white rectangle on top not covering anything. It needs to be tilted by a particular angle as mentioned in the json file to be over the FLASH SALE area. x and y always represents the top left corner of the bounding box.
Thank you in advance!
...ANSWER
Answered 2021-Jun-09 at 20:19I think your question is "how to draw a rotated bounding box when you have only the upper left corner of the box and its dimension and rotation angle". If this is correct, then you can do this from the geometry and trigonometry of the rotated bounding box via Python/OpenCV or any other tool using the following diagram and mathematics.
Given that we know (X1,Y1), width W, height H and angle theta for the rotation. Here we use the convention that the rotation is counter-clockwise positive as in the diagram. Using the right angle subtended at the top, we can compute (X2,Y2) as
QUESTION
I run my Android app (based on Java), and it works. Next, I add to my app code:
FirebaseFirestore fdb = FirebaseFirestore.getInstance();
This code I got from the official Android site https://firebase.google.com/docs/firestore/quickstart
App runs, but next the running device shows the message "app has stopped".
I use a device simulator available in Android Studio.
It is my first Android app, and I can't understand what is going.

Answered 2021-Jun-09 at 03:39At the end of your log, just before the initial crash. there is a warning:
Default FirebaseApp failed to initialize because no default options were found. This usually means that com.google.gms:google-services was not applied to your gradle project.
simply adding com.google.gms:google-services should fix any issues you have, if you have issues, ensure your Gradle cache is cleared or run without the build cache
