certainty | Automated cacert.pem management for PHP projects | TLS library

I understand the certainty argument to mean:

certainty - a measure of the uncertainty that the caller is willing to tolerate: if the call returns true the probability that this BigInteger is prime exceeds (1 - 1/2^certainty)

From my experiments, it seems to exceed it by quite a lot! The code below finds "probable primes" between 2 and 1 million and checks against a set of definite primes to see if it was a false positive.

I'm using a certainty argument of 2. I therefore expect that only 75% of "probable primes" will be actual primes. (1 - 1/2² = 0.75 = 75%.)

Actually, it gets it right 99.9% of the time.

Is my understanding of the meaning of "certainty" correct? I suspect it might not be if the certainty I've seen experimentally exceeds my expectation by so much.

I want to write a code that can be used on different XML files (all with TEI encoding) to see if specific elements and attributes appear, how often they appear and in what context). To do this I have written the following code:

I am parsing large projects with many thousand XML files for specific Elements and Attributes. I have managed to print all the Elements and Attributes I want but I cannot write them into a CSV Table. It would be great if I could get every occurrence of every Element/Attribute under the respective headers. The Problem is that I get "NameError: name 'X' is not defined", I do not know how to restructure, everything seemed to be working fine with my variables until I moved them to a CSV.

I'd like to examine the Psychological Capital (a construct consisting of four dimensions, namely hope, optimism, efficacy and resiliency) of founders using computer-aided text analysis in R. So far I have pulled tweets from various users into R. The data frame contains of 2130 tweets from 5 different users in different periods. The dataframe is called before_failure. Picture of original data frame

I have then used the quanteda package to create a corpus, perfomed tokenization on it and removed redundant punctuatio/numbers/symbols:

How to convert BigDecimal to BigInt in Scala?

I am trying to run the following code:

Is there a way to infer the type of a model's attribute based on some kind of parameter?

I'm trying to type the return type of a method that returns a list of objects like for example:

I have read about Except here. I am still a bit confused. I am using .NET 4.8.

I have 7 different implementations of my custom interface IMyInterface. All these implementations are held in a List or IEnumerable. I am doing the following in many places of my project (pseudocode):

I can see lots of copied lore that functions registered with the .init_array section have the command-line arguments argc and argv, like main(), but I am failing to find any actual published documentation online that confirms that this is the case.

Yes, for clarity, the function itself is not "declared in" the .init_array, but a pointer to the function is declared there, "registering" the function, and it is called by some iterator during start-up. Question remains: show me some documentation for the argument list passed in by that iterator.

My intent is to change these arguments from a dynamic library in a subtle but generally safe way, so I want to find the "real deal" in memory - not from /proc/self/.

Some Stack-overflow lore: Accessing main arguments outside of main on Linux

Even my favoured Oracle ( docs.oracle.com/cd/E23824_01/html/819-0690/chapter3-8.html ) only mentions that the functions get called, but no promise of what arguments there might be. Same with the elf and gcc documentation, as far as I can see.

In the land of C/C++ UB paranoia, Ideally I need some certainty that this is documented behaviour before I go ahead with it? Does it exist? Can it be implied in some way?

Summary of comments/answers so-far:

At least for GNU libc, a relevant change occurred with this patch: BZ #974. https://sourceware.org/pipermail/libc-alpha/2005-July/019240.html (It is mentioned in glibc's ChangeLog.old/ChangeLog.16 entry 2005-04-13 H.J. Lu.) – Ian Abbott

To me, this demonstrates that the glbc maintainers were aware of the requirement to pass argc/argv/env - that it is not accidental - and extended it to main exe registrations. It also tells us that it was working for dynamic libraries prior to that date.

It is an interesting question whether this binds other libc implementers to follow the pattern.

Hey guys so I'm building a websocket using flask and I'm currently creating a new thread for every request so that thread can do some heavy processing and not take too much time to return something from the request. The problem is that at some point i get so many threads open that it starts causing problems and i was wondering if i could setup some queue in flask to limit the app for creating like 8 thread each time only.

My code:
