I'm not sure if it fits your usecase but I'm using Jellyfin and it works really well.
Re:A tiny Pacific country rolls out universal basic income on Monday November 02, 2026 @04:05AM (#50334561)
I didn't mean its job is to mitigate employment crises I meant its job is to give people (everyone) income/wealth.

I accept a significant amount of conditionality here - it's cool that people can get rich and live materially better lives by doing stuff that creates more wealth overall. But this is completely subordinate to the goal of making everyone's life better, i.e. I accept it exactly to the extent that "a rising tide lifts all boats". It seems the rising tide of AI may not automatically lift all boats though.

Anyway yeah your point stands, I realise this is not something everyone automatically believes. I'm phrasing it like a statement of fact just because I believe it so strongly.

Re:A tiny Pacific country rolls out universal basic income on Sunday November 01, 2026 @08:10AM (#50325319)
What could possibly by dark and cynical about that? This is the only way we can possibly deal with mass unemployment.

Also, 6 million people forced to spend their waking lives driving trucks is not a good thing. The thing that's good about that is the income they get from it. If we create enough wealth to give them the income without the truck driving... We won? That's the goal here. That's what the economy is _for_. Employment is the way the economy has always achieved that, but it doesn't meant employment is the goal, it's a means to an end.

Re:New iMac with M6 on Wednesday October 28, 2026 @10:41AM (#50274471)
My extremely non-technical mum is using a 2008 MacBook Air on Ubuntu, it works great. Claude says the iMac is essentially the same to get running.

Only hassle was setting up the Broadcom WiFi drivers which aren't upstream, but I did this before I would have trusted AI with this task and even then it was not a big deal. I think these days running Linux on those things is likely trivial.

You can also just run Bitmagmet for a few weeks and then you have your own tracker. (I think "tracker" might be technically incorrect jargon but it solves the same problem).
Re:C for Rust Programmers on Thursday October 15, 2026 @04:23AM (#50100822)
The thing that defeats your point is that there is no consequential C codebase that has dynamic allocation and no UAF. There simply isn't an argument to be had here, it's an empirical question and it's settled. It's time to move on and adopt memory safe languages. There are no valid excuses any more now that Rust is basically tolerable.

If you wanna claim this is a skill issue and you are built different etc, fine. I guess we can just say C is fundamentally unsafe for _everyone except you_.

(This is like when people wanna argue about if self driving cars are safe or not and they're blathering on about technical capabilities and limitations. No. We have the data).

Re:C for Rust Programmers on Sunday October 11, 2026 @05:36AM (#50041343)
Sorry but no, this is totally wrong. There is no set of compiler flags or design practices that can fix the lack of lifetime analysis in C.

I do actually think that with modern C++ it's possible to get to a style of programming where memory unsafety is mostly a theoretical concern but not with C.

Re:C for Rust Programmers on Sunday October 11, 2026 @05:33AM (#50041321)
I do tend to think people under use bitfields.

I suspect this is because they are usually introduced like "here are bitfields, but DO NOT USE THEM for anything that might become ABI because their order is implementation defined". I think that causes people to mentally file it under <sketchy language features to avoid> when actually there are many contexts where the ABI risk is not real.

> Rowhammer says hi

Yeah I was thinking of prefixing my "memory corruption" with "software-bug induced"! I don't see a credible solution to Rowhammer. ("DDR[n+1] fixes it" - lol)

> an unsafe block, an FFI boundary

Honestly these feel solvable to me at this point! I think we'll see:

- unsafe code shrink as languages get more powerful

- amount of analysis we can apply to each unsafe line shoot up exponentially as AI gets cheaper

- amount of FFI we actually need shrink as it gets easier to just click "rewrite it in $lang" on the decision card when your coding agent says "I found a library for that but it's in a different language"

(Having said all of that, people seem to be adopting Zig for some bizarre reason... So maybe I'm naive to expect unsafe lines to shrink)

(But also, maybe AI gets so good and so cheap that we can just type "go fidn all the bugs andfi xthenm" into an LLM, between sips of a Piña Colada)

Re:C for Rust Programmers on Saturday October 10, 2026 @09:13AM (#50032612)
'bool' is still at least 1 byte in C. If you want to store one Boolean per bit you have to manually implement a bitmap.
Re:C for Rust Programmers on Saturday October 10, 2026 @09:11AM (#50032597)
It's beautiful to see this perspective! The fact that we are at "whoa, C is fucked up compared to my expectations" instead of "look at Rust's fancy safety stuff" shows that as a field we've started lifting the baseline.

Nowadays I actually believe I'll likely see a world without memory corruption within my lifetime.

Re:Transit rewards (Waymo pays you to take the train) on Wednesday September 23, 2026 @03:13AM (#49812685)
Does anyone know what the play here is?

(Is it given that there's a play? Waymo is culturally a little distinct from Google so from personal experience I can't actually rule out that they're just doing this coz they think it would be good for the world).

I don't think it makes much sense to expect such a cohesive/specific philosophy from an open source project like this.

The goal is "Linux on Mac". In a commercial product, specific details of what gets built usually stem from a more detailed vision that can be articulated as one. In open source projects those details are determined by what individual contributors are motivated to work on.

That doesn't means a cohesive vision can't emerge, there might be one for Asahi actually. But I think the default position is that it's kinda just a mob of people doing what they each feel like doing.

Re:A Note from LWN on Wednesday September 02, 2026 @11:39AM (#49537945)
I think LWN is not just the best linux news site or the best tech news site, or the best new site. I think it's actually the best website. I just can't think of anything else that comes close in terms of quality of information.

If you have any professional connection at all to Linux then $11/mo is an absolute bargain!

Re:Polishing Cloth Updated on Tuesday September 01, 2026 @10:15AM (#49522319)
The Asahi folks have been making really impressive progress on Polishing Cloth drivers so I'm optimistic that we'll at least have a community solution for the E-waste in future decades.

> Is there any type of sidebar/footnote that you, as a reader, would like to see to denote AI usage during the writing and/or research process?

It's not something I expect, but I definitely don't see an issue with people putting a couple of sentences in an "expand to see AI usage notes" tab at the top or bottom of the page.

> Would you expect none?

As in, would I expect no AI usage? Coz no I absolutely expect people to use AI.

If you had got Claude to do this investigation for you then actually I think that would have been notable enough to include details of your AI workflow. But not because "it's cheating not to disclose it", rather because you'd probably have come up with quite a neat workflow that is interesting in its own right.

Re:I Think the Military Commissary's Freezers Were Hacked on Monday August 31, 2026 @05:18PM (#49514953)
I came to these comments coz I was curious about the AI usage here, and FWIW I also thought it smelled AI written, but I didn't think it was slop. (IMO not all AI output is slop and not all slop comes from AI).

My main question was "did Claude do the investigation by itself or just write up the article from someone's notes?"

Also though, I'm quite willing to believe this is human written and the human just happens to have a Claudey style. The actual prose isn't that Claudey it's just the structure of how it presents ideas. But, Claude had to get that structure from somewhere. It's not that surprising to see people with that style of communication.

Re:Breaking Claude Code Opus 5 Auto Mode on Monday August 31, 2026 @01:04PM (#49512075)
Hmm yeah that's never really been my read on Auto Mode but I guess it's still worth pushing back on any messaging that seems to imply "Auto Mode is all you need".

I would reject "Auto Mode is safe" as a message but FWIW I am totally on board with "on aggregate, making Auto Mode the default improves the safety of Claude Code compared to the prior status quo". Coz I would say in the vast majority of cases the access classifier is doing a better job than the thing it replaced.

Anyway yeah. Like I said, conclusion is the same: we should be decoupling this from the harness. We ought to be sandboxing agents the same way we sandbox applications. I wish Claude Code would make this path smoother :(

Re:Understanding ChatGPT Work on Monday August 31, 2026 @11:18AM (#49510815)
It's funny coz it seemed like they also cloned the confusion.

I don't really understand what Claude Cowork is. Sometimes I use it instead of plain Claude Chat for tasks that "feel big"? And when I've done that I've felt this was the right choice. But until I actually had that session up and running I would not be able to articulate what Cowork is or enumerate any specifics of how I expected it to behave. I just thought "maybe this is a Cowork task?"

(I have only used the cloud one. My understanding is the the local app is essentially Claude Code but for non-coders, which matches the description of the OpenAI equivalent).

Even as someone who's now used it a few times I wouldn't have been able to articulate as many details as Simon W does in this article, it's a weirdly shaped product structure.

Re:Breaking Claude Code Opus 5 Auto Mode on Monday August 31, 2026 @11:00AM (#49510607)
Yeah I jumped on this quite excitedly but it's not prompt injection at all.

To be fair to the authors they don't actually say it is. But then they contrast it with the "0.00% prompt injection attack success rate".

The upshot is kinda the same - this is still evidence that we should be sandboxing our agents. But it doesn't actually challenge Anthropic's "our models are too clever to prompt-inject" vibe.

Re:Debian votes to allow "responsible use of generative AI" on Saturday August 29, 2026 @11:29AM (#49490730)
Before I left Google recently there was a document going around called go/stake-your-reputation, basically saying "I'm happy to receive your AI generated code but the condition is that I will judge your capabilities by it, exactly as if you handwrote it, and I'll lower my opinion of you if it's slop (with the implication that if you don't improve I'll stop accepting your contributions)"

I think the term "stake your reputation" is quite good for this situation. I.e. "hi new contributor, please acknowledge that you Stake Your Reputation before we move ahead with this code review".

(Doesn't help with legal aspects of course)

Re:Disrupting a new covert influence campaign from Russia on Wednesday August 26, 2026 @05:53AM (#49446352)
I am, for some reason, quite active commenting on Reddit. And lately the number of comments I see that are obviously Claude has skyrocketed. These are just engaging in normal innocuous comment threads about the day to day stuff I care about (tech, my local region, stuff like that). But obviously they are building organic-looking profiles that can then be exploited to push manipulative content later.

This scares me because the stuff that screams "THIS COMMENT WAS WRITTEN BY CLAUDE" has gotta be the tip of the iceberg. There must be much more of these comments that are better-prompted and using better-tuned model pipelines to make them less detectable. (Probably even just the lazy garbage is harder for me personally to detect if you just pass the prompt to GPT instead of Claude, it's just that I've read so much Claude output that I'm attuned to it).

So yeah suddenly dead internet theory is seeming a lot more real today than it did just a couple of months ago.

It means you can comment on the problematic commits saying "please squash this". Then (if it works as well as Gerrit) you can compare the commit between the before and after squash state.

Basically it lets you treat the commits as part of the thing you are reviewing instead of just a minor detail that the UI doesn't care about very much.

Correct, it was a typo that I only spotted after I lost the ability to edit.
Yeah I get occasional dropouts in the setup I installed at my mum's place too.

And yeah it's just a bit of a weird black box, and also fundamentally it's exploiting a nontrivial system to do something that had little relationships to its design goals. I don't know anything about electrical systems but I assume there is all kinds of random shit that can disrupt Powerline links while still being fully within the design envelope of the power system.

It's a Unifi Dream Router 7. The 6GHz doesn't reach through the wall IIRC
(Repeating myself coz I saw this after writing my sibling comment..)

It's highly variable in my experience. I've had it work pretty well in some situations and barely at all in others.

I have certainly never got 1000mbps. I think I have got 300 at best. In my office I can only get about 50 even though it works pretty well in other parts of the same small apartment.

... Which is kinda annoying coz they aren't really all that cheap for something you have to just buy and then find out later if it actually works!

Yeah I have tried it! It beats WiFi to some rooms, but to my office it's very slow.

You would never be able to predict this, which is an unfortunate thing about powerline IMO. You just have to buy the modems and see how they perform on your particular wiring.

Yeah I was considering this actually, but then I realised that I really want a working LAN 100.0% of the time, so I'd only go tinker mode if I had a backup. So I was gonna be buying a router regardless.

Now I have a Ubiquiti one, it's antithetical to my DIY instincts but I think I'm OK with my router being one of the proprietary appliances in my life.

Plus now the wired section of my LAN is really fast.
