kandi X-RAY | fp Summary
This is a C++14 header-only fixed-point arithmetic library. It’s purpose is to wrap another type and provide fixed point arithmetic support on top of it. It’s designed to be able to wrap on top of all the built-in arithmetic types (integers and floating point types) as well as user defined arithmetic types. Examples of other arithmetic types which are tested and preliminary adapters are provided: * boost rational * boost multiprecision cpp_int and cpp_bin_float * David Stone’s bounded_integer.

QUESTION
I am working on a project where I get emails with a specific 'subject'. There are forwarded to me by users. The body consists of text but in the original email and no new text is entered above the forwarded line. There are also attachments to either of the part of the email.
I wrote the following code using python and IMAP and am able to store attachments and body only if the email is NEW and not a forwarded email.
...ANSWER
Answered 2021-Jun-15 at 22:07Seems like you already have the part where you are extracting the attachments. Try this code to retrieve the body of a multipart email.
You may have to figure out how to merge your part with this one.
QUESTION
In my iOS app "Progression" there is rarely a crash (1 crash in ~1000+ Sessions) I am currently not able to fix. The message is
Progression: protocol witness for TrainingSetSessionManager.update(object:weight:reps:) in conformance TrainingSetSessionDataManager + 40
This crash points me to the following method:
...ANSWER
Answered 2021-Jun-15 at 13:26While editing my initial question to add more context as Jay proposed I think it found the issue.
What probably happens? The view where the crash is, contains a table view. Each cell will be configured before being presented. I use a flag which holds the information, if the amount of weight for this cell (it is a strength workout app) has been initially set or is a change. When prepareForReuse is being called, this flag has not been reset. And that now means scrolling through the table view triggers a DB write for each reused cell, that leads to unnecessary writes to the db. Unnecessary, because the exact same number is already saved in the db.
My speculation: Scrolling fast could maybe lead to a race condition (I have read something about that issue with realm) and that maybe causes this weird crash, because there are multiple single writes initiated in a short time.
Solution: I now reset the flag on prepareForReuse to its initial value to prevent this misbehaviour.
The crash only happens when the cell is set up and the described behaviour happens. Therefor I'm quite confident I fixed the issue finally. Let's see. -- I was not able to reproduce the issue, but it also only happens pretty rare.

I have problem with my bpf program. I getting error while loading this program. my bpf program is:
...ANSWER
Answered 2021-Jun-15 at 07:28TL;DR. You should check that the pointer returned by bpf_map_lookup_elem is not NULL.
With the following logs, the BPF verifier is telling you that, when it reaches the dereference of my_pid, the pointer may still have a NULL value. It thus contains a map value or a NULL value, i.e., map_value_or_null.

Is a simple way to convert pdf to html using pdfminer? I have seen many questions like this but they won't give me a right answer...
I have entered this in my ConEmu prompt:
...ANSWER
Answered 2020-Dec-31 at 10:17In regards to your second code snippet with the ImportError: cannot import name 'process_pdf' from 'pdfminer.pdfinterp' I suggest checking this GitHub issue.
Apparently process_pdf() has been replaced by PDFPage.get_pages(). The functionality is nearly the same (with the parameters you used (rsrcmgr, device, in_file, pagenos=[1,3,5], maxpages=9) it works!) hence check the implementation on-site.

QUESTION
I'm trying to create a QFileDialog with filtering on the file extension and file name. The file extension can be filtered via setNameFilter(), but name filtering (as far as I know) can only be filtered by creating a custom dialog and proxy model and then overriding the filterAcceptsRow() function.
I should be returning True when I want a file to show up in the dialog and False when I don't. The trouble is that when I return based on the custom checking I get no results. But when I return True always (even when I execute the check and print out based on it), I see all of the expected files. If it weren't for the printout I'd think I'm creating the pattern improperly, but that's not the case. And each button that opens this dialog sends a different value for file_part so I can't hard-code the pattern.
I have replaced my first attempt at example code with a toy example that hopefully showcases the problem. In my test environment, C:\temp\ contains the following files:
0bbb_record2_part1.txt0bbb_record2_part2.txt0jjj_record1_part1.txt0jjj_record1_part2.txt0jjj_record2_part1.txt0jjj_record2_part2.txt0jjj_record3_part1.txt0jjj_record2_part2.txt
ANSWER
Answered 2021-Jun-10 at 01:31The problem is that you're filtering everything, including the directory that is going to be shown. If the current selected path doesn't match the regex, then the index for that path won't be accepted, and the result would be an empty file dialog (since that path "doesn't exist").
A possible solution is to check that if the index is a directory:

QUESTION
Yesterday me and a few colleagues were trying to get a toy example for applicative validation in fp-ts to work. We finally got it working with manually storing each interim step in a variable and calling the next step. But it would be way more elegant using the pipe function from fp-ts. Doing it with Either directly works, but does not combine multiple Left values into one (e.g. concatenating arrays with string errors). But with pipe() the ap()-calls want two arguments, but only get one. How do we use pipe correctly here:
...ANSWER
Answered 2021-Jun-11 at 15:52Either.getApplicativeValidation returns an instance of Applicative2C which has non-pipeable versions of the class methods. Currently, the way you get pipeable versions of instances computed with combinators (like getApplicativeValidation) is to pass the instance to the pipeable combinator from the pipeable.ts module.
So change your code to this:
