    NEW: 20 civil society organisations have called for an investigation into the UK Information Commissioner's Office for failing to uphold data protection law in relation to eVisas.

    This scheme has been plagued with breaches and accessibility issues.

    And the ICO has done nothing to hold the UK Home Office to account.

      A drug is a chemical substance and object.

      A social media platform is a complicated system of speech and communication.

      Using anaology that conflate the two is at best lazy thinking, at worst prohibitionist propaganda from people with authoritarian personality types.

      Almost 25 years ago, I wrote a blog post with the title ‘jumping ship slowly’ about leaving Windows (XP was awful, it was mind boggling to me that Vista managed to make people nostalgic for XP). My advice remains the same:

      Don’t try switching OS first. The OS is the most easily replaceable bit in the stack. Switch applications first. Most ‘Linux’ apps are cross platform. They’ll run on Windows, and the few that don’t will run in WSL2. You can switch out apps one at a time, and take the time to get comfortable with the alternatives.

      Once you’re comfortable not using any Windows-only apps, changing the OS but using all of the same applications is very easy to do. Changing OS and application stack at the same time is an enormous obstacle.

      I believe this is also why a lot of corporate and government Linux migrations fail: they try to change everything at the same time and that’s too steep a learning curve.

                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!

                      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.

                            As a person who is running Matrix from 2018 until now, it seems I made my choice to switch to xmpp.
                            Currently in a process of migrating people to the new platform.

                            As someone here stated about Matrix:
                            "wait another 2 years and see if it's gotten any better. Well, this hasn't expired yet".

                            I'm tired of waiting too.

                            Also, xmpp is far from being perfect, but

                            - it works stable
                            - lite weight (both clients and server),
                            - works pretty well on poor network conditions.
                            - better for 1:1 chats
                            - AV calls are flawless.

                                        Yeah! Feeling cuddly great!
                                        Can you see I've new stuffing???
                                        But now finally NOMPF!

                                        A Blåhaj cuddly shark sitting on a table with a plate with two Dutch cheese sandwiches in front of them. A Smolhaj cuddly shark and a small black crotched octopus with colourful bead tentacles are watching.

Glad everything went well! And the scar is neat. And it seems you are already recovered! Amazing!

                                            Wanted to see me speak at but couldn't make it? Here's the two talks I gave!

                                            How to Level Up the Fediverse

                                            Can't get enough? Need more talks? We gave a bunch... 🧵

                                              Another FOSDEM and hackathon are in the rear-view mirror, and it is hard to find words to describe how amazingly productive and fun the experience was! We met so many people at the postmarketOS stand, in the FOSS on Mobile devroom and at dinners in the evening. As always it is fun to put faces to nicknames and to talk about the Linux Mobile ecosystem, and figure out how to improve it in person.
