QUESTION
I was trying to create a thread safe queue, but something went wrong. I can't understand why does my thread freeze. Expected: 1 2 3, but i get nothing (everything just freezes)
I guess the problem is misuse of condition variable in front (pop) and get (peek) methods, but I can't find my mistake. Could you please point out my mistake and explain what the mistake is?

QUESTION
I'm looking for a method to send data from userspace to bpf program in Linux.
I use libbpf in userspace and bpf_helpers in bpf program in kernel.
I now can send data from kernel to user by ringbuf and other.
but I want to use stack and queue for this. I can't find function that handles queue or stack in userspace and I still confused.
My question is: how can I send data from userspace to bpf program using stack or queue and get it in my bpf program, as what we do in bcc with bpf['queue'].push
in userspace for example and queue.peek(&val);
in bpf program.
thank you for any help!
...ANSWER
Answered 2021-Jun-15 at 07:42You should use the usual bpf_map_update_elem
and bpf_map_lookup_elem
functions for BPF_MAP_TYPE_QUEUE
and BPF_MAP_TYPE_STACK
maps.
You can find several examples in the kernel source code:

I have a List

This is a part of my code, before data augmentation, model.fit
was working, however after augmentation of data i'm getting this error;
AttributeError: module 'scipy.ndimage' has no attribute 'interpolation'
This is the list of all imported libraries;
...ANSWER
Answered 2021-Jun-13 at 10:55I found the problem. Problem was that scipy
was missing in my anaconda virtual environment. I thought scipy
was installed when I saw;
AttributeError: module 'scipy.ndimage' has no attribute 'interpolation'
Thanks for the tip @simpleApp. And I'm sorry to bother you with the mistake of absent-mindedness... Solution is the installing scipy

QUESTION
UPDATE IN ANSWER BELOW
Is anyone else experiencing the newest couple versions of chrome causing issues with legacy Java applications? Just yesterday I needed to get the company's policy manager to allow downloading files from an internal unsecured server by adding our URLs to a whitelist - you can see the details of the process on the chromium blog here. That issue was present in v90 as well.
What I'm currently experiencing due to the v91 update is as follows: My boss was trying to use a page in one of our Java 6 legacy applications and he noticed that the page wouldn't return the data in any format - we checked and he was already v91. I was on v90 and the page worked fine. After updating Chrome to v91, I'm getting the same broken page as my boss.
I was thinking it might be something related to the CSS but I don't have time to poke at it and redeploy the legacy app every time to test the changes. Though, I have taken a peek at this chromium blog post for version 91. Though I don't see much relating to what may have caused the removal of all non-label fields and the formatting of the label fields are all wonky and out of place.
I'm going to look into investigating the struts tile that holds the code JSP code; if I find something I'll post it here for reference.
The first image below is what one row should look like with the header above it. As you see in the second picture, all there is the header with improper formatting and the grid is gone.
...ANSWER
Answered 2021-Jun-10 at 21:45I have determined the problem to be the
tag. In the newest version (v91) of Chrome, the table rendering engine has been rewritten. the notes are here and if you want the in-depth documentation, is the link to the Google Doc that the developers wrote. Basically, the old way of rendering tables has become obsolete and the Workaround: Disable the chrome flag named Enable TableNG
and restart your browser.
Addition: I found chromestatus, a website that shows new features being added, deprecations, etc.
tag is now defunct.QUESTION

QUESTION
I have a service that runs as a console app and outputs to stdout and stderr streams to the console. The developers don't want to add any logging capabilities since it was mainly designed for linux world and they have tools like logroate and other means already but don't care about the windows port. I want to redirect those streams into a log and I'm able to do it like this: service.exe 2>&1 >> service.log
But if I leave this running this log will grow out of control. So I tried using something called logrotateWin but it needs to rename the log file and I get access denied since its in use. So I'm trying to write another app that can write to logfile and rotate it based once a day and only keep last n logs.
I want to be able to run it like: service.exe 2>&1 | logrotater.exe
So I'm trying to write logrotater with the following code but it seems to fail to read the stream from the pipeline. It can read the stream if it stops like from a simple echo "test" command source, but not from service.exe that continuously keeps streaming data out. Any suggestions?
So this works: echo "test" | logrotater.exe
But this doesn't work: service.exe 2>&1 | logrotater.exe
...ANSWER
Answered 2021-Jun-08 at 19:15Add a Log()
method that opens and closes the file as needed. Moving to a separate method will make it easier to isolate these changes from the rest of the program. One easy way to open/close as needed is with File.AppendAllText()
.

This question is based on the answers to this question What is the difference between Stream.of and IntStream.range?
Since the IntStream.range
produces an already sorted stream, the output to the below code would only generate the output as 0

ANSWER
Answered 2021-May-25 at 05:50How exactly this is done is very much an implementation detail. You will have to dig deep inside the source code to really see why. Basically, parallel and sequential pipelines are just handled differently. Look at the AbstractPipeline.evaluate
, which checks isParallel()
, then does different things depending whether the pipeline is parallel.
QUESTION
I would like to remove messages that are scheduled to be delivered to a specific queue but i'm finding the process to be unnecessarily burdensome.
Here I am sending a blank message to a queue with a delay:
...ANSWER
Answered 2021-Jun-08 at 04:00In order to remove specific messages you need to know the ID which you can get via a browse of the scheduled messages. The only other option available is to use the start and stop time options in the remove operations to remove all messages inside a range.
