kandi X-RAY | four Summary

four is a Ruby library typically used in Tutorial, Learning, Example Codes applications. four has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

We've all done this:. What the fuck? Ruby is conspicuously missing support for four-letter words. Luckily, the four gem immunizes Ruby against it's own childish impudence. Install it and be yourself again.

QUESTION

repeat values of a column based on a condition

Asked 2021-Jun-16 at 00:54

I have a data frame including three columns named 'Altitude', 'Distance', 'Slope'. The column of 'Slope' is calculated using the two first columns 'Altitude', 'Distance'. @ the first step the purpose was to calculate 'Slope' using a condition explained below: A condition function was deployed to start from the top column of the "Distance" variable and add up (sum) values until the summation of them is greater or equal to 10 (>=10). If this condition corrects then calculate the "Slope" using the given formula: Slope=Average(Altitude)/(sum(Distance)). The summation of the 'Distance' was counting from the first value of that to the index that the 'Distance' has stopped there). The following code is for the above explanation (By Tim Roberts):

How do I check user input against multiple lists python?

Asked 2021-Jun-16 at 00:51

How do I check user input against multiple lists python?

Ex. I want to check if an input is in one of four lists. One list for up down left and right. Each list has the different acceptable ways to make the program continue. Once the input is verified to be in one of the lists i will need to figure out how to make it check against the individual lists so that the input correlates correctly to the desired direction.

Custom characters are used in two spots but they print properly.

QUESTION

Using std::atomic with futex system call

Asked 2021-Jun-15 at 20:48

In C++20, we got the capability to sleep on atomic variables, waiting for their value to change. We do so by using the std::atomic::wait method.

Unfortunately, while wait has been standardized, wait_for and wait_until are not. Meaning that we cannot sleep on an atomic variable with a timeout.

Sleeping on an atomic variable is anyway implemented behind the scenes with WaitOnAddress on Windows and the futex system call on Linux.

Working around the above problem (no way to sleep on an atomic variable with a timeout), I could pass the memory address of an std::atomic to WaitOnAddress on Windows and it will (kinda) work with no UB, as the function gets void* as a parameter, and it's valid to cast std::atomic to void*

On Linux, it is unclear whether it's ok to mix std::atomic with futex. futex gets either a uint32_t* or a int32_t* (depending which manual you read), and casting std::atomic to u/int* is UB. On the other hand, the manual says

The uaddr argument points to the futex word. On all platforms, futexes are four-byte integers that must be aligned on a four- byte boundary. The operation to perform on the futex is specified in the futex_op argument; val is a value whose meaning and purpose depends on futex_op.

Hinting that alignas(4) std::atomic should work, and it doesn't matter which integer type is it is as long as the type has the size of 4 bytes and the alignment of 4.

Also, I have seen many places where this trick of combining atomics and futexes is implemented, including boost and TBB.

So what is the best way to sleep on an atomic variable with a timeout in a non UB way? Do we have to implement our own atomic class with OS primitives to achieve it correctly?

(Solutions like mixing atomics and condition variables exist, but sub-optimal)

You shouldn't necessarily have to implement a full custom atomic API, it should actually be safe to simply pull out a pointer to the underlying data from the atomic and pass it to the system.

Since std::atomic does not offer some equivalent of native_handle like other synchronization primitives offer, you're going to be stuck doing some implementation-specific hacks to try to get it to interface with the native API.

For the most part, it's reasonably safe to assume that first member of these types in implementations will be the same as the T type -- at least for integral values ^[1]. This is an assurance that will make it possible to extract out this value.

... and casting std::atomic to u/int* is UB

This isn't actually the case.

std::atomic is guaranteed by the standard to be Standard-Layout Type. One helpful but often esoteric properties of standard layout types is that it is safe to reinterpret_cast a T to a value or reference of the first sub-object (e.g. the first member of the std::atomic).

As long as we can guarantee that the std::atomic contains only the u/int as a member (or at least, as its first member), then it's completely safe to extract out the type in this manner:

You could loop through the bars and test whether it is completely to the right of the separation, completely to the left or crosses it. You change the bar's color correspondingly.

When a bar crosses the separator, the bar gets the color for the left area and its size is narrowed to touch the separator. A copy of the bar can be added, with the right-area color and its x-position moved.

What is happening in your code:

You have an object coord. You are pushing its reference to the array, in each iteration. All your array elements point to coord. You are changing the properties of the object coord again in turn changing your array elements.

Calculate percentage of HIV cases in different US States using R

Asked 2021-Jun-15 at 14:40

I am having a dataset which contains the absolute HIV cases of four US State over 2 years.

There are three columns date (Jan 2018, Feb 2018 ...) , state (CA, NY, FL, MA) , and abs_cases in the data frame. I am ignoring the population changes in those 2 years in the respective states.

I now want to calculate the relative cases for each state using the population for each state which I googled. (I will just use fantasy numbers here) pop<- "CA"= 11111, "NY"= 22222, "FL"= 33333,"MA"= 444444.

ANSWER

Answered 2021-Jun-15 at 14:40

Without an example dataset, here is my guess at what you are trying to do. You can convert pop into a dataframe using enframe and join it to df by state. Then, you can compute the cases per population by each State in each month.
