            I started using pdb while writing some stuff in , and it's really nice to interact with!

            I like that:

          • You can define breakpoints just using the breakpoint() function, making conditional breakpoints very natural:
          • if [condition]:
            breakpoint()
          • You don't need any special invocation to start the debugger - just run the script as you normally would and you end up in a pdb shell when a breakpoint is hit.
          • In other languages, I slightly dread starting a debug session because I have to remember the flag to pass extra args, add all the breakpoints on startup etc. This leads to long sessions because I don't want to lose the investment I've put into my breakpoints.

            But in Python, I have much shorter debug sessions and I can get right to a point of invocation really quickly, verify something, and close the debugger straight away.

          • It interacts nicely with the repl:
          • I use the repl much more because I can end up in a repl right with the context and variables that I need.

            Defining more breakpoints within the repl is really nice to unpack nested datastructures in the same way it would be done in the code:

            >>> for key, some_list in some_dict.items():
            ... for value in some_list:
            ... breakpoint()
            I end up writing things in the repl first, but within the context that the code would be written in reality.

            It's really thoughtfully designed - thank you to the people who made it so!

              Y'all, this is the game where we get LOCKED OUT of having ANY real FOSS operating system we control AT ALL

                  A story of date ranges when exporting transactions from 3 financial companies:

                  "Want transactions for the whole of Jan, without any transactions from 1 Feb?"

                  Bank 1: Export 1 Jan to 1 Feb 😎
                  Bank 2: Export 1 Jan to 31 Jan 🙂
                  Bank 3: Export 1 Jan to 30 Jan!! 🤦

                  How does that happen?! It must be inclusive on both ends, plus the 1 Feb transaction happens at midnight? All I know is, if you go to 31 Jan, it will pull 1 Feb into Jan's export!

                      So you probably don't want to reject AI generated content not because "AI generated content Is incompatible with your license if it has no copyright" but because "whether or not AI generated content is subject to copyright is not a settled matter and ESPECIALLY NOT INTERNATIONALLY" (and not everywhere has a public domain). If you accept something, its status may not be the same internationally, and *legal decisions about AI output could change soon*, leading to an integration of something very hard to undo later.

                      And the OTHER reason to not integrate it is that most of AI generated output has subtle bugs and tends to result in an erosion of your community. So yeah, that too.

                                          Two things:
                                          1. We are creating a two-tiered internet that will see people willing to give up their IDs having one experience while those who can’t, won’t, or don’t have them missing out on those experiences or being outright excluded from whole areas of the web

                                          2. Why you would be willing to give up your ID to web services that have such poor security in a time when identity is being weaponized by state actors is beyond me

                                          Loads of FOI requests going into Ofcom about how they are monitoring VPN use. They are refusing to answer most of them. We know they are paying Apptopia and the contract is here contractsfinder.service.gov.uk
