• Weekly report 9, LLVM-libc

  Hi! This week I’ve pretty much finished the work on LLVM/Clang support
  for Crossdev and LLVM-libc ebuild(s). I have sent PRs for Crossdev and
  related ebuild changes here:

  https://github.com/gentoo/crossdev/pull/10
  https://github.com/gentoo/gentoo/pull/32136
  This PR includes changes for compiler-rt which are always needed for
  Clang crossdev, regardless of libc. There are also changes to musl,
  kernel-2.eclass (for linux-headers), and a new eclass, cross.eclass.

• Firefox Developer Experience: Firefox WebDriver Newsletter — 116

  WebDriver is a remote control interface that enables introspection and control of user agents. As such it can help developers to verify that their websites are working and performing well with all major browsers. The protocol is standardized by the W3C and consists of two separate specifications: WebDriver classic (HTTP) and the new WebDriver BiDi (Bi-Directional).

  This newsletter gives an overview of the work we’ve done as part of the Firefox 116 release cycle.

• Hubert Figuière: Niepce July 2023 updates

  This is the July 2023 update for Niepce.

  Where we left, the workspace tree view didn't display the hierarchy.

  First, I discovered bug in the SQL triggers for folder path update. I was missing the AFTER keyword to have it run after the update.

  [...]

  For now I chose 3. The risk is that if the parent doesn't exist then the tree will stay lingering. It's just the view though.

• Pandas Apply() Function to Every Row

  In Python, the “df.apply()” function applies the specified functions, such as user-defined, lambda or Numpy functions along the axis of the input DataFrame.

• ThreadPoolExecutor Python

  The “thread pool executor” in Python is a robust mechanism that efficiently manages threads, allowing developers to effectively parallelize their programs.

• Pandas GroupBy Index

  The “groupby()” method in Python is utilized to split the Pandas DataFrame into groups based on the specified index value.

• Pandas Split Columns by Delimiter

  In Python, the “Series.str.split()” function takes the “delimiter” and “expand=True” as an argument to split the string columns by delimiter.

• How to use Python readline() function
