@AsahiLinux mad props to Faith and Lina and all the Asahi contributors working together on this.

@AsahiLinux again again I am in awe what you all at asahi to get these M1/M2 thingies somewhere where they can be used with linux. chapeau!

The "Recall can't record DRMed video content" thing is because DRMed video content is entirely invisible to the OS. The OS passes the encrypted content to your GPU and tells it where to draw it, and the GPU decrypts it and displays it there. It's not a policy decision on the Recall side, it's just how computers work.

@mjg59 Thank you for explaining that. Now it makes more sense.

Pusher of Pixels

@mjg59 Interesting. So 'recall' still does the screen capture but the parts that are DRM'd just aren't visible?

Aaron Sawdey, Ph.D.

@mjg59 It is a hardware design decision that tells you where their priorities lie and who they are willing to protect.

After 2000, *lots* of people sneered that the Y2K bug had been a big nothing, massively overhyped.

They were idiots. If the vast amount of Y2K remediation that took place hadn't, planes might well have fallen from the sky, nuclear power plants might well have melted down. I worked on two projects myself to fix bad 2 digit dates.

We get to the other side of the current Nazi infestation, the same idiots are going to say, "See, you were just hysterical."

@fatsam The Y2K mitigations were done quietly behind the scenes, that's why people thought nothing happened. Do you figure that beating fascism will happen quietly
Jacqueline Jannotta

@fatsam same with pandemic measures and vaccines. Imagine where we’d be if none of that happened.

@fatsam Recently I found this Y2.1K bug in the datetime encoding code of a smart home product/ecosystem. I wonder how many instances of this are present out there in the wild.

Joshua Barretto

My brother-in-law
sent me an opinion piece
(from the paper of record)
offering five points
purportedly showing
how the pandemic
started in a laboratory,
so I asked him
what steps he was taking
to protect himself
from this lab escapee,
and I could tell
he did not like my question

@mattblaze "the man who sank the Clipper ship" 😃 - I remember reading about that kerfuffle over in the UK back then. Thanks so much for sharing both that and the paper!

*swoosh hand* Oh, that rascal… I wonder if he ever stopped that “hacking” nonsense and made anything of himself.

I'm really really really not interested in computers getting more powerful.
I am super interested in them being more repairable and modifiable, drawing less power, lasting and being supported for way longer etc. That stuff still gets me excited

@Shrigglepuss agreed. same

I'm writing (slooooowly) a book about sw/hw performance

@Tamasg @Shrigglepuss In a long term, we must remake all of the hardware and software architectures in order for them to become simpler. the simpler, the more repairable.

@Shrigglepuss@godforsaken.website I wanna see everything get cheaper, the only thing that needs increases is storage.

I want a 50 euro machine in 10 years to do what 500 euro does today

As a general rule, the state should over-supply services. There should be slack in the system almost all the time. Relaxed GPs with lots of time to talk to their patients. So many teachers that the main trouble is finding rooms for them all.

Not only does this see a better quality of service mostly, but it also cushions the system in the event of an unexpected shock.

If you have just enough professionals to deliver at 100%, you don’t have enough professionals.

@Tupp_ed But that's not financially efficient so we won't be able to deliver value for our shareholders!

Alice Dubiel 🔬💉🦠😷🌬

@Tupp_ed Not having adequate slack in a services or social system means running on crisis management which feeds on the myth of individual consciousness. One result is no adequate evaluation. Without evaluation and analysis of statistics, patterns, trends, planning strategies depend increasingly on biases, whimsy and desperation instead of best practices or even common sense. Capitalism and militarism exploit crisis management.

@Tupp_ed this is currently most evident in the UKs national health service. We have, for many years, tried to run this at near 100% capacity, both in terms of staff time and beds and equipment. This when demand is clearly seasonal. Basic queuing theory shows that when you push anywhere near 100% you end up with a permanent queue, which is what we see. Add in unexpected crises, like COVID, and the queues explode and staff end up totally exhausted and many quit, which makes it worse.

Joshua Barretto

This is a remarkable graph.

You might have heard that "EV sales are slumping", "people are starting to avoid EVs", etc.

That's not what's happening.

What's happening is "Tesla is cratering so hard that it's skewing the aggregate market data."

Or, put differently, "Tesla is failing harder than the entire rest of the market is succeeding, combined."

@mhoye but that still means less people are buying EVs overall..

Local Dad, Ben Hamill

@mhoye @spencer I know that for our family, who bought a used model S a buncha years ago, we'd never buy from Tesla again even if Musk wasn't giving us political reasons for that decision. They treat their cars like they're cell phones: You're meant to regularly upgrade or they slowly get shittier and shittier. And because they act like a tech company, rather than a car company, a lot of parts of the car (windows, screen, dashboard, door handles, speedometer console, etc) is just super badly made.

We're almost certainly looking at a VW EV for our next vehicle.

This is a bit of a stretch, but does anybody have experience implementing frustum polygon clipping, in software, in a very resource-constrained environment? I've some questions I'd love to ask.

My current approach seems to be unviable, it's taking up more of my frame time than rasterisation!

#gamedev #demoscene

Räucherkäse

@jsbarretto Do you need to truly clip the triangles (i.e. generate new vertices at the frustum boundary), or would simple culling be enough?

Just woke up. Turns out, I didn't dream the election up. So now I'm grumpy.

@joelanman Just applied for a postal vote from my phone while watching TV. Always a pleasure using gov.uk.

Simon Hobeck

@joelanman I was in a planning session today looking at how we improve comms across the services around deadlines (such as registering in time or applying for postal).
Announcement of the GE will force us to push ahead fast to get something in time.

Robin Whittleton

@joelanman did both register to vote and apply for a postal vote within 10 minutes of the Guardian notification, thanks!

@faassen One thing about traits is that it makes thinking about Rust code closer to how I think about relational databases.

I am reminded of

"Show me your flowchart and conceal your tables, and I shall continue to be mystified. Show me your tables, and I won't usually need your flowchart; it'll be obvious." -- Fred Brooks, The Mythical Man Month (1975)

which significantly shaped how I think about problems. Traits + ADTs put you in the same frame of mind.

As always, domestic abuse is _the_ flagship infosec threat model, the one where the victim has the least resources, the least recourse, where they're closest to immediate physical harm.

That this industry has failed at and mostly abandoned the idea of even pretending to try dealing with a threat model that's difficult and unprofitable and mostly hurts women is not news, but this new Windows Recall feature is next-level professional negligence.

Dennis Schubert

@mhoye I got called an "AI hater" for pointing out exactly that (and the potential abuse by law enforcement) in mastodon.schub.social/@denschu and ... in a chat-thingie.

I love working in tech. :this_is_fine:

(but, to be fair to them, "AI hater" *is* correct.)

@mhoye change the xkcd cartoon from govt agents beating someone with a wrench to an abusive husband beating someone with a wrench, and maybe these sheltered nerds will believe it.

Joshua Barretto

A lot of people who are not experts in domestic abuse think they're making a clever point by informing me that if an abuser has physical access & login credentials, the game's already over.

I am very tired and do not have the energy to explain why making spying easier for abusers is bad, actually.

coldclimate

@evacide thank you for all you do. I am sorry that reply guys even dare.

Asta [AMP]

@evacide@hachyderm.io For people that work in an industry that prides itself on how they're all experts at scaling shit and "delivering exponential value", it's "funny" how they can never be made to understand how scaling harmful things also exponentially magnifies the harms.

Mathaetaes

@evacide I assume I missed a post about how Microsoft’s new Recall feature is a potential nightmare for people who are being abused or are otherwise associated with abusive or controlling people, and this is in response to the “well actually” crowd?
