  • You are not comparing like for like.

    Twitter is pretty much 20 years old, so are Facebook, Reddit and YouTube.

    In addition, they were essentially first of a kind in their niche.

    The fediverse is not even a teenager and the growth spurt hasn’t set in and may never. In addition, the fediverse is utilitarian by comparison, not much beyond proof of concept. Apps, platforms and instances are fragile and evolving.

    Basic things mostly work, but it’s not “cool” enough to tempt organisations to join, media companies, etc.

    We barely agree on how things interact with each other, for example, Mastodon uses hashtags, Lemmy doesn’t.

    Lemmy has communities, Mastodon doesn’t.

    It’s not that one is better than the other, it’s still being worked out by the community.

    You also have to remember that there have been many “failures” along the way. Geocities, MySpace, Usenet, AOL, bulletin boards and bang path addressing. The fediverse might succeed, whatever that means, or it might not.

    I’m a user on Mastodon, Lemmy and Bluesky, they’re evolving day by day. I’m not sure if I could tell you what I like or dislike about each, they’re just different.









  • Have a look at your AWS billing console, since data egress is charged and downloading to verify is considered egress.

    AWS S3 supports data checksums where a checksum is calculated at AWS, which you can compare against a checksum that you calculate locally.

    This is an article that goes into how it works, but I’ve not (yet) tested it, but I’ll be following in your footsteps pretty soon.

    As an aside, make sure that versioning is OFF on your backup bucket unless you specifically require and understand it, because even when you delete objects, they persist as a previous, all but invisible, and charged(!), version.

    My former backup software “helpfully” enabled versioning and I was left with a $600 monthly bill for six months while there was no actual backup being done due to a local hardware failure, until I figured out what was happening. I used that software for years and shudder to think just how much extra it actually cost.

    I will note that while I had a catastrophic hardware failure, I didn’t lose any data.

    Finally, if you’re storing data in Glacier, retrieval is charged at different rates, depending on timelines of access, so it might be that your backup software is using the slow tier to “save” you money.

    Edit: OP advises that they’re not using AWS, instead they’re using OVH. The object storage solutions appear to be mostly compatible, but I was unable to discover if the OVH implementation supports checksums.







  • Uhm … no.

    Linux had permissions from day one, neither Windows nor Apple did until much more recently.

    I use Apple, since there’s many versions of its OS and only¹ the one based on BSD has permissions.

    The entire Linux ecosystem is permissions based, it’s baked into the kernel and while bugs continue to be discovered and patched, they’re visible to everyone, where that’s not the case with either Windows nor Apple.

    Permissions aren’t new. Unix has had them from the early days, as have operating systems like VMS, BSD and OS/400 to name a few.

    As for exploits, the level of user social engineering exploits is exploding with the growth of Linux, since most new users come from operating systems with poor security.

    In my opinion Mac OS is hurting itself by making inexplicable security choices, causing pain where none is required, resulting in people actively disabling security to their own detriment.

    As for actual exploits, they’re getting more and more ubiquitous since more and more operating systems are running the same code, think python, nginx, bash, etc.

    Finally, I’d point out that your attempt at dispelling what you call a myth does not appear to be backed up by facts or sources.

    I’ve been in this industry for over 40 years and while it’s far from perfect, I am comfortable stating that Linux is more secure than many operating systems and I suspect that it will continue to be the case for the foreseeable future.

    I also note that it has a significantly larger user base than any other OS. Don’t believe me? Heard of Android, same Linux kernel.

    ¹ There was a brief A/UX hybrid OS that had permissions, based on Unix System V and BSD. It was discontinued in 1995.



  • Fortunately my name is Onno and I speak Dutch from time to time 😁

    Interestingly, in reading that Dutch article it appears this has been in the works since 2020 when Amsterdam banned fossil fuel advertising. It was copied in several other cities, and the ban that came about today was an enhancement of the previous decision, banning among other things, meat products, flights and cruises, and fossil fuel vehicles.

    I think that it’s a very interesting approach to encouraging societal change. Australia banned cigarette, alcohol and gambling ads to drive change in a similar way.

    Unfortunately much of that content is now pushed online instead, so I’d hazard that Amsterdam will need to encourage this across the entire country and then via broadcast media and online before it becomes ubiquitous.
