QUESTION
I am creating part of one tool, which merges two SAP exports into one.
I know how many account numbers might be in the export (not all of them every month) and I have it almost complete except for the find issue, when account number is not in dataset, but is found and data merged are from the last exported account number

QUESTION
I'm experimenting with Chaum's blind signature, and what I'm trying to do is have the blinding and un-blinding done in JavaScript, and signing and verifying in Java (with bouncy castle). For the Java side, my source is this, and for JavaScript, I found blind-signatures. I've created two small codes to play with, for the Java side:
...ANSWER
Answered 2021-Dec-13 at 14:56The blind-signature library used in the NodeJS code for blind signing implements the process described here:
BlindSignature.blind()
generates the SHA256 hash of the message and determines the blind message m' = m * re mod N.BlindSignature.sign()
calculates the blind signature s' = (m')d mod N.BlindSignature.unblind()
determines the unblind signature s = s' * r-1 mod N.BlindSignature.verify()
decrypts the unblind signature (se) and compares the result with the hashed message. If both are the same, the verification is successful.
No padding takes place in this process.
In the Java code, the implementation of signing the blind message in signConcealedMessage()
is functionally identical to BlindSignature.sign()
.
In contrast, the verification in the Java code is incompatible with the above process because the Java code uses PSS as padding during verification.
A compatible Java code would be for instance:

QUESTION
I posted a similar question to this one a few weeks ago where I had trouble finding the data race in my N-queens program using pthreads in C. Why is my multithreaded C program not working on macOS, but completely fine on Linux?
I got a few suggestions in the comments sections of the post and I really tried my best to make corrections based on them. I sat with the suggestions a few days, changed some parts but the data race persisted and I just cannot understand why. There are counters inside critical sections for the number of productions and consumptions. I feel completely blind when looking through the code and analyzing it, I'm aware that consumptions are too many but the synchronization around that code fragment should with my knowledge be correct, but obviously something's not right. External input would be greatly appreciated.
This is the code I'm using and I'm not sure how to reduce its size to still reproduce the issue. I compile it with gcc (clang-1205.0.22.11) on macOS Monterey (12.1) using a MacBook Pro 2020 x86_64 architecture.
compile: gcc -o 8q 8q.c*
run: ./8q
, NxN chess board, N queens to place
parameters: ./8q 2 4
Enough to highlight the problem (should yield 2 solutions, but every other run yields 3+ solutions, i.e duplicate solutions exist
note: running the program with ./8q 2 4
should give 2 solutions, 1820 productions and 1820 consumptions.

QUESTION
How do I get -e
/ errexit to work in bash functions, so that the first failed command* within a function causes the function to return with an error code (just as -e
works at top-level).
* not part of boolean expression, if/elif/while/etc etc etc
I ran the following test-script, and I expect any function containing f
in its name (i.e. a false
line in its source) to return error-code, but they don't if there's another command after. Even when I put the function body in a subshell with set -e
specified again, it just blindly steamrolls on through the function after a command fails instead of exiting the subshell/function with the nonzero status code.
I get the same result in all of these envs/shells, which is to be expected I guess unless one was buggy.
Arch:
bash test.sh
(bash 5.1)zsh test.sh
(zsh 5.8)sh test.sh
(just a symlink to bash)
Alpine:
docker run -v /test.sh:/test.sh alpine:latest sh /test.sh
(BusyBox 1.34)
Ubuntu:
docker run -v /test.sh:/test.sh ubuntu:21.04 sh /test.sh
docker run -v /test.sh:/test.sh ubuntu:21.04 bash /test.sh

Call the function not inside if
.
I expect any function containing f in its name (i.e. a false line in its source) to return error-code
Weeeeeell, your expectancy does not match reality. It is not how it is implemented. And flag errexit
will exit your script, not return error-code.
Desired output
You can:
Download Bash or other shell sources or write your own and implement the behavior that you want to have.
- consider extending the behavior with like
shopt -s errexit_but_return_nonzero_in_if_contexts
or something shorter
- consider extending the behavior with like
Run it in a separate shell.

I need to make a old code base compatible with Python3. The code needs to support Python2.7 and Python3 for some months.
I would like to add this in very file:
...ANSWER
Answered 2022-Jan-31 at 16:32If all you need is to ensure that the Source Code Encoding Heading and the 4 import statements are present, then the following script will recursively descend through a directory modifying all .py files ensuring that these the required statements are present. The updates will be done in place, so it could be wise to make sure that you have a backup in case of a hardware failure in the middle of rewriting one of the files. Even if the code is rewritten to write to a temporary file and then do a final "move" to replace the old with the new, the same problem remains.
You should try this out on experimentally first in a test directory, and as always, USE AT YOUR OWN RISK.

Answered 2022-Jan-08 at 08:32You are obviously trying to store the result of the division into a float
, but floats also include integers.
You're actually performing an integer division, because, in both cases, both of your terms are integers (don't have a fractional part).
The division is performed rounded (result being without a fractional part), and is assigned to your variable.
How to correct this? Try adding a fractional part to at least one of the two numbers. For example:
QUESTION
I am building a website with NextJS that takes some time to build. It has to create a big dictionary, so when I run next dev
it takes around 2 minutes to build.
The issue is, when I run next export
to get a static version of the website there is a timeout problem, because the build takes (as I said before), 2 minutes, whihc exceeds the 60 seconds limit pre-configured in next.
In the NEXT documentation: https://nextjs.org/docs/messages/static-page-generation-timeout it explains that you can increase the timeout limit, whose default is 60 seconds: "Increase the timeout by changing the staticPageGenerationTimeout configuration option (default 60 in seconds)."
However it does not specify WHERE you can set that configuration option. In next.config.json? in package.json?
I could not find this information anywhere, and my blind tries of putting this parameter in some of the files mentioned before did not work out at all. So, Does anybody know how to set the timeout of next export? Thank you in advance.

Answered 2021-Dec-21 at 10:13They were a bit more clear in the basic-features/data-fetching part of the docs that it should be placed in the next.config.js

QUESTION
A Fortran code I am working on has several lines similar to
...ANSWER
Answered 2021-Oct-28 at 21:59Execution1 of the write
statement of the question has always been explicitly prohibited.
We currently see (F2018 12.6.4.5.1 p7):
During the execution of an output statement that specifies an internal file, no part of that internal file shall be referenced, defined, or become undefined as the result of evaluating any output list item.
filename
is an internal file, and the evaluation of the output list item filename
is a reference to that internal file.
This is not a programming violation that the compiler is required to detect, so you can view this as a case of improved diagnostic capability/pickiness of the compiler as you desire. No Fortran program is harmed by the change in this behaviour of the compiler.
Fortran 66 didn't have internal files (or character types), of course, and Fortrans 77, 90 and 95 used different words for the same effect (see for example, F90 9.4.4):
If an internal file has been specified, an input/output list item must not be in the file or associated with the file.
In case it looks like this is more restrictive, from Fortran 2003 the restrictions for input and output statements are stated separately (only output was quoted above, p8 for input).
1 Note the use of execution: there's nothing wrong with the statement itself as a statement. It is allowed to exist in source code that isn't reached. Checking this statement when compiling is not a simple matter.
