Since your function "..has many optional parameters" and passengers parameter requires a dictionary as an input, I would suggest you create a Pydantic model, where you define your parameters, and which allows sending your data in JSON form and getting them validated, as well as converting the model to a dictionary using the dict() method.

That's because for does word splitting etc. when its input is a command's output. See Don't Read Lines with For in the bash wiki for details.

One alternative is to use bash's extended globbing features instead of find:

Draw raw array of pixels onto a window (C++ WinAPI)

Asked 2022-Jan-09 at 17:23

I have two buffers, both of the same size and type (uint32_t*). These buffers are supposed to represent the front and back buffers of a rendering/drawing system. They store 32-bit pixel data.

ANSWER

Answered 2022-Jan-09 at 17:23

You can't draw to an arbitrary window by poking bytes into some buffer. Win32 is a higher level API than that.

It is possible to draw into a bitmap by writing into a buffer, however. You create a bitmap such that Windows returns a pointer to its contents when you create it with CreateDIBSection(...). You can then paint that bitmap to a Window via BitBlt and appropriate device contexts, etc.

Below is a minimal example. (I retained your usage of a back buffer and front buffer even though it isn't really necessary here. The window itself is essentially a front buffer so you would only really need "a swap chain" of one back buffer to not have flickering.)

QUESTION

NLM UMLS MRREL is broken / incomplete

Asked 2021-Dec-19 at 05:31

I have been working with the Unified Medical Language System (UMLS) for decades. But I have been aware for some years now (since 2017) that the MRREL table is woefully defective. And I wonder how can that possibly be?

I have tons of examples, but I am just making it very simple. The ATC code is a simple tree. Among many others, there is a top-level category 'G' (CUI: C3653431) and another 'C' (CUI: C3540036).

Answered 2021-Aug-16 at 06:43

I have sent a problem report to NLM and they replied that the file in the UMLS-Full.zip, the ones that end in .nlm, that also contain the UMLS data tables, are somehow incomplete and one needs their MetamorphoSys program to assemble the right files.

It seems like they do some data compression (for whatever reason) in rows by which they can reduce the size of the MRREL file by about 20%.

QUESTION

How to find if a value differs from the previous line and repeat that information in next line (like a loop)?

Asked 2021-Sep-14 at 13:56

Problem

The title is misleading, since it is more complex than that. I need to find the difference of value between 2 lines but from 2 different variables, and I also need to repeat that information to all rows below.

I have a list of patients, who came in and out of the hospital where I work. Sometimes, during the hospitalisation, they are moved from an unit to another unit (emergency to intensive care for example).

I want to know how many time they actually left then returned to the hospital.

To find that, I simply need to search for a time difference between the entry day and the previous exit day. If both are equal, then this is the same stay. If they differ, then it is another stay.

It is kinda hard to explain with my english level, so I present you an example below.

Example

I work with data.table, but you can use dplyr if you wish to. I should be able to convert it easily.*

ANSWER

Answered 2021-Sep-14 at 12:58

First, you have to prepare your dataset - you basically want only to compare NEXT entry with PREVIOUS exit. There will be no previous exit for first entry, so first entry could be deleted, and there will be no entry for last exit.
