There will be a FOSS meetup on Saturday 8th August 2026 near Baker Street, called by Polarian!

I hope to be there once I finish with work, probably a couple of hours after it starts.

GLLUG post.

It's not a reserved venue, so look for a table with lots of stickers, and Polarian wearing the EuroBSDCon 2024 (Dublin) tshirt (with artwork like this).

      @tarakiyee interesting thoughts in commons and copyleft in The age oft AI. E.g. ". A model trained on GPL code is not automatically a covered derivative work merely because that code was somewhere in the corpus. It's a defence built against one specific enemy hailing back to the 80s, the proprietary fork."

        I dusted off an old idea to show duration for walking segments of public transit itineraries that I played with a year or so back.

        Now that the list is using flowboxes, which can wrap contents to multiple lines when needed I think it will probably look better:

          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.

            Utopia & Dystopia by Dylan Glynn

            A side-by-side crayon or oil pastel drawing split into two panels labeled "UTOPIA" and "DYSTOPIA." The left panel, titled "UTOPIA" in green text, shows a lush, green tree with a thick canopy standing on a patch of grass against a light, rain-streaked background. The right panel, titled "DYSTOPIA" in red text, shows a fiery red, orange, and yellow mushroom cloud erupting against a dark, black background, resembling a nuclear explosion.

                        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!

                                  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.

                                        The government must change the Terrorism Act so future ones don't make similar proscriptions with worse consequences.

                                        With the ban still in place, we need to hear how Ofcom expects platforms to remove content.

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

                                                  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.
