kandi X-RAY | bus Summary
Bus provides a lock-free, bounded, single-producer, multi-consumer, broadcast channel. It uses a circular buffer and atomic instructions to implement a lock-free single-producer, multi-consumer channel. The interface is similar to that of the std::sync::mpsc channels, except that multiple consumers (readers of the channel) can be produced, whereas only a single sender can exist. Furthermore, in contrast to most multi-consumer FIFO queues, bus is broadcast; every send goes to every consumer. I haven't seen this particular implementation in literature (some extra bookkeeping is necessary to allow multiple consumers), but a lot of related reading can be found in Ross Bencina's blog post "Some notes on lock-free and wait-free algorithms". See the documentation for usage examples.

QUESTION
I am fairly new to Tensorflow and I am having trouble with Dataset. I work on Windows 10, and the Tensorflow version is 2.6.0 used with CUDA. I have 2 numpy arrays that are X_train and X_test (already split). The train is 5Gb and the test is 1.5Gb. The shapes are:
X_train: (259018, 30, 30, 3),
Y_train: (259018, 1),
I create Datasets using the following code:
...ANSWER
Answered 2021-Sep-03 at 09:23That's working as designed. from_tensor_slices is really only useful for small amounts of data. Dataset is designed for large datasets that need to be streamed from disk.
The hard way but ideal way to do this would be to write your numpy array data to TFRecords then read them in as a dataset via TFRecordDataset. Here's the guide.

The easier way but less performant way to do this would be Dataset.from_generator. Here is a minimal example:

I have a map-stype dataset, which is used for instance segmentation tasks. The dataset is very imbalanced, in the sense that some images have only 10 objects while others have up to 1200.
How can I limit the number of objects per batch?
A minimal reproducible example is:

This problem is because when keras run with gpu, it uses almost all

I am implementing a simple chatbot using keras and WebSockets. I now have a model that can make a prediction about the user input and send the according answer.
When I do it through command line it works fine, however when I try to send the answer through my WebSocket, the WebSocket doesn't even start anymore.
Here is my working WebSocket code:
...ANSWER
Answered 2022-Feb-16 at 19:53There is no problem with your websocket route. Could you please share how you are triggering this route? Websocket is a different protocol and I'm suspecting that you are using a HTTP client to test websocket. For example in Postman:
HTTP requests are different than websocket requests. So, you should use appropriate client to test websocket.

QUESTION
I am making a decentralized exchange in which I am trying to implement a search functionality where users put either token address, name, or symbol. But the challenge I am facing is that when users search for tokens like BUSD the token present in the user wallet will come on top.
for example:-
suppose I have these tokens in my wallet and I am getting this response from web3
...ANSWER
Answered 2022-Jan-11 at 09:42Perhaps this approach would be helpful. First filter the results that are in and out of the wallet, and then combine them into one array.
QUESTION
I have been learning buffer overflows and i am trying to execute the following command through shellcode /bin/nc -e /bin/sh -nvlp 4455. Here is my assembly code:
ANSWER
Answered 2021-Dec-29 at 14:12As you can see in strace, the execve command executes as:
execve("/bin//nc", ["/bin//nc", "/bin//nc-e //bin/bash -nvlp 4455"], NULL) = 0
It seems to be taking the whole /bin//nc-e //bin/bash -nvlp 4455 as a single argument and thus thinks it's a hostname. In order to get around that, the three argv[] needed for execve() is pushed seperately.
argv[]=["/bin/nc", "-e/bin/bash", "-nvlp4455"]
These arguments are each pushed into edx, ecx, and ebx. since ebx needs to be /bin/nc, which was already done in the original code. we just needed to push 2nd and 3rd argv[] into ecx and edx and push it into stack. After that we just copy the whole stack into ecx, and then xor edx,edx to set edx as NULL.
Here is the correct solution:

I'm currently doing an assignment for a SQL class and can't seem to figure out how to go on from this. Going on from what I have I can't seem to average the counts per occupation. With what I have so far I see how many books each person borrowed. If I try to average the column it just averages everything together when I need it specifically by occupation. Also, I Grouped by clientId because each client has multiple books borrowed.
The assignment is The average number of borrowed books by job title.

QUESTION
We are working on a project which allows us to record some sounds from a microphone with a 5k Hz sample rate with some Low-Pass filter & HighPass filter.
What we are using
We are using AvaudioEngine for this purpose.
We are using AVAudioConverter for downgrading the sample rate.
We are using AVAudioUnitEQ for the LowPass & HighPass filter.
Code
...ANSWER
Answered 2021-Dec-17 at 10:50I think the main problem with this code was that the AVAudioConverter was being created before calling engine.prepare() which can and will change the mainMixerNode output format. Aside from that, there was a redundant connection of mainMixerNode to outputNode, along with a probably incorrect format - mainMixerNode is documented to be automatically created and connected to the output node "on demand". The tap also did not need a format.
QUESTION
I'm transferring 16 bit numbers from a STM32 (from an ADC) over SPI to raspberry pi 4. On the pi side, I have a script that runs in a loop, waits for a GPIO pin to go high to act as a "detect" for my system to then enable the raspberry pi to initiate the SPI transfer. Unfortunately the raspberry pi hardware only supports 8 bit SPI and so the numbers I'm getting back are split across 2 x 8 bits. The data I'm transferring:
