QUESTION
I want to create a toString function for Tuples with a variadic amount of a specific type (arithmetic types for now).
Something like this

QUESTION
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)
...ANSWER
Answered 2021-Jun-15 at 20:48You 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::atomictou/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:
QUESTION
I'm writing a Firebase function (Gist) which
Queries a realtime database ref (events) in the following fashion:
await admin.database().ref('/events_geo').once('value').then(snapshots => {Iterates through all the events
snapshots.forEach(snapshot => {Events are filtered by a criteria for further processing
Several queries are fired off towards realtime DB to get details related to the event
await database().ref("/ratings").orderByChild('fk_event').equalTo(snapshot.key).once('value').then(snapshots => {Data is prepared for SendGrid and the processing is finished
All of the data processing works perfectly fine but I can't get the outer await (point 1 in my list) to wait for the inner awaits (queries towards realtime DB) and thus when SendGrid should be called the data is empty. The data arrives a little while later. Example output from Firebase function logs can be seen below:
10:54:12.642 AM Function execution started
10:54:13.945 AM There are no emails to be sent in afterEventHostMailGoodRating
10:54:14.048 AM There are no emails to be sent in afterEventHostMailBadRating
10:54:14.052 AM Function execution took 1412 ms, finished with status: 'ok'

I'm probably mixing up my async/awaits because of the awaits inside the await. But I don't see how else the code could be written without splitting it out into many atomic pieces but that would still require stitching a bunch of awaits together and make it harder to read.
So, two questions in total. Can this code work and what would be the ideal way to handle this pattern of making further processing on top of data fetched from Realtime DB?
Best regards, Simon

QUESTION
I am a beginner learning from a tutorial on how to change the colour of a selected area of a picture with a range of colour options.
I can figure out how to change one area, but unsure how to implement the other areas.
What I want to achieve is to click on the selected area, it highlights the border (CSS), then change the colour by using the colour options.
What is the best way to implement this? I'm I correct in thinking maybe a switch statement with onclick to select the specific area of the picture?
...ANSWER
Answered 2021-Jun-15 at 11:48You could try having a "select" function run when you click on one of the areas. This function would "highlight" the area (border-color), and save the id of the area in a variable.
Then when you click on the color swatches another function would run that will take the value previously saved id and select the HTML element based on that.

I have this kind of input as below. It is a list of strings, every odd string is a number starting with MR and every even string is some mixed text. I need to convert this list of strings to a pandas data-frame which strictly has two columns, but because some of the MR numbers are present several times paired with different mixed text counter parts I am getting extra columns everywhere where an MR is repeated, as I am demonstrating below:

QUESTION
I'm getting some very weird behavior from mixing tidyverse and data.table syntax.
For context, I often find myself using tidyverse syntax, and then adding a pipe back to data.table when I need speed vs. when I need code readability. I know Hadley's working on a new package that uses tidyverse syntax with data.table speed, but from what I see, it's still in it's nascent phases, so I haven't been using it.
Anyone care to explain what's going on here? This is very scary for me, as I've probably done these thousands of times without thinking.
...ANSWER
Answered 2021-Jun-15 at 06:35I came across the same problem on a few occasions, which led me to avoid mixing dplyr with data.table syntax, as I didn't take the time to find out the reason. So thanks for providing a MRE.
Looks like dplyr::arrange is interfering with data.table auto-indexing :
- index will be used when subsetting dataset with
==or%in%on a single variable- by default if index for a variable is not present on filtering, it is automatically created and used
- indexes are lost if you change the order of data
- you can check if you are using index with
options(datatable.verbose=TRUE)
If we explicitely set auto-indexing :

I wanted to make a circle cursor and I copied the code from codepen
I am working in another IDE called Repl.it and so I copied the exact same code from codepen to repl.it (Note: I did use the correct code from codepen by compiling it first)
The code is not working in repl.it
I am not sure what I am missing, but I am pretty sure it has to do with the tags. Any help would be much appreciated.
