Hi, security professional here! A lot of the time, we don't need it.

The central point of this app is to determine proximity of two devices. That's not possible today in a cross-platform way using web apps.

The Quick 861DW has been a hobbyist favorite for a long time, and comes in at ~$300 (USD)

For modern systems, stack buffer overflow bugs haven't been great to exploit for a while. You need at least a stack cookie leak and on Apple Silicon the return addresses are MACed so overwriting them is a fools errand (2^-16 chance of success).

Most exploitable memory corruption bugs are heap buffer overflows.

Yep! 60t/s on the 8 bit MLX on an M4 Pro with 64GB of RAM.

There's MLX versions of the model, so yes. LM Studio hasn't updated their mlx-lm runtime yet though, you'll get an exception.

But if you're OK running it without a UI wrapper, mlx_lm==0.30.0 will serve you fine.

It means more surface (both from extensions themselves and the loader code), relaxation of things like KTRR/CTRR (you now need to add executable EL1 pages at runtime), plus the potential for signing keys to leak (Finding enterprise signing keys even for iOS is fairly easy).

As far as Windows goes, https://www.loldrivers.io is a thing.

I do vulnerability research. Those things would do the exact opposite of what you're aiming for. They'd be received with glee by mercenary spyware companies, _especially_ being able to load things into higher levels of privilege.

You're confusing your opinion of the company with the perception by the general public. Apple's definitely not perceived as 'an office appliance company' by your average person. It's considered a high-end luxury brand by many[1].

It'd run on a 5090 with 32GB of VRAM at fp8 quantization which is generally a very acceptable size/quality trade-off. (I run GLM-4.5-Air at 3b quantization!) The transformer architecture also lends itself quite well to having different layers of the model running in different places, so you can 'shard' the model across different compute nodes.

From what I've been reading the inference workload tends to ebb and flow throughout the day with much lower loads overnight than at for example 10AM PT/1PM ET. I understand companies fill that gap with training (because an idle GPU costs the most).

So for data centers, training is just as important as inference.

I believe they mean the source region's tag, rather than the destination.

I have some inside knowledge here. KPP was released around the time KTRR on A11 was implemented to have some small amount of parity on

Concerta is extended release methylphenidate. It is not an amphetamine.

This isn't a transformer, it's a diffusion model. You can't split diffusion models across compute nodes.

Just from my limited experience:

Barton Springs in Austin is always brimming with people and Shiner Bock makes a frequent appearance.

Dolores Park in SF never has a dull moment and you can buy shrooms or edibles from vendors walking around.

Golden Gate Park in SF is massive and there are tons of clusters of people socializing and drinking throughout the park (especially near the Conservatory of Flowers!)

Central Park in NY in many ways mirrors Golden Gate Park only its way busier. Good luck finding a spot near the south side of the park on a sunny day. You might spot a mimosa or two, three…

Something is lost as well if you do 'research' by just asking an LLM. On the path to finding your answer in the encyclopedia or academic papers, etc. you discover so many things you weren't specifically looking for. Even if you don't fully absorb everything there's a good chance the memory will be triggered later when needed: "Didn't I read about this somewhere?".

Yep. Though if you don't place any of them - depending on how technical you want to get - that's a DE0.
