AzN1337c0d3r··on TSA lines are so out of control that travelers are hiring line-sitters
Were you born after 2001? Did you remember those planes that flew into the buildings?

Private planes can do the same thing.

What's new about this with the H2 chip?

My H1-chipped USB-C Airpods Max (OG) seem to switch seamlessly between my iphone, ipad, and macbook pro already.

AzN1337c0d3r··on Can I run AI locally?
Maybe things have changed but the last time I looked at this, it was only max 96GB to the GPU. And it isn't dynamic in the sense you still have to tweak the kernel parameters, which require a reboot.

Apple has none of this.

AzN1337c0d3r··on Can I run AI locally?
Most workstation class laptops (i.e. Lenovo P-series, Dell Precision) have 4 DIMM slots and you can get them with 256 GB (at least, before the current RAM shortages).

There's also the Ryzen AI Max+ 395 that has 128GB unified in laptop form factor.

Only Apple has the unique dynamic allocation though.

Insurance is likely using that same data to adjust rates.

Bought by Broadcom, now implementing classic strategy of leveraging vendor lock-in to milk customers.
AzN1337c0d3r··on The great software quality collapse or, how we normalized catastrophe
There's almost never a death where there is a single factor, regardless of aviation or not. You can always decompose systems into various layers of abstractions and relationships. But software bugs are definitely a contributing cause.
AzN1337c0d3r··on The great software quality collapse or, how we normalized catastrophe
> If all the examples you can conjure are decades old

They're not ALL the examples I can conjure up. MCAS would probably be an example of a modern software bug that killed a bunch of people.

How about the 1991 failure of the Patriot missile to defend against a SCUD missile due to a software bug not accounting for clock drift, causing 28 lives lost?

Or the 2009 loss of Air France 447 where the software displayed all sorts of confusing information in what was an unreliable airspeed situation?

Old incidents are the most likely to be widely disseminated, which is why they're most likely to be discussed, but that doesn't mean that the discussion resolving around old events mean the situation isn't happening now.

AzN1337c0d3r··on The great software quality collapse or, how we normalized catastrophe
Not to be pedantic, but people have died from software programming bugs being a primary contributing factor. One example: Therac-25 (https://en.wikipedia.org/wiki/Therac-25)
AzN1337c0d3r··on Microsoft CTO says he wants to swap most AMD and Nvidia GPUs for homemade chips
I would submit Google's TPUs are not GPUs.

Similarly, Tenstorrent seems to be building something that you could consider "better", at least insofar that the goal is to be open.

AzN1337c0d3r··on Doom crash after 2.5 years of real-world runtime confirmed on real hardware
> Back in the real world, no race team would agree that their cars should disintegrate after one race.

Wasn't F1 teams basically doing this by replacing their engines and transmissions until the rules introduced penalties for component swaps in 2014?

AzN1337c0d3r··on Nvidia is full of shit
They don't just specify 12 smaller cables for nothing if 2 larger ones will do. There are concerns here with mechanical compatibility (12 wires have smaller allowable bend radius than 2 larger ones with the same ampacity).
AzN1337c0d3r··on Nvidia won, we all lost
They are not the exact same thing.

AzN1337c0d3r··on Apple has announced its final version of macOS for Intel
Actually, the keyboard mechanism that the M1 MacBook Pros got was from the 2019 16-inch Intel MacBook Pro (which was the first 16-inch MacBook Pro).

So the 2019 16-inch MacBook Pro and the 2020 13-inch MacBook Pros got non-butterfly keyboards.

AzN1337c0d3r··on Building an AI server on a budget
Depends on the server. Probably not going to be cost effective. I get barely ~0.5 tokens/sec.

I have Dual E5-2699A v4 w/1.5 TB DDR4-2933 spread across 2 sockets.

The full Deepseek-R1 671B (~1.4 TB) with llama.cpp seems to have a in that local engines that run the LLMs don't do NUMA aware allocation, so cores will often have to pull the weights in from another socket's memory controllers through the inter-socket links (QPI/UPI/Hypertransport) and bottleneck there.

For my platform that's 2x QPI links @ ~39.2GB/s/link that get saturated.

I give it a prompt, go to work and check back on it at lunch and sometimes it's still going.

If you're going to want to achieve interactively I'd aim for 7-10 tokens/s, so realistically it means you'll run one of the 8b models on a GPU (~30 tokens/s) or maybe a 70b model on an M4 Max (~8 tokens/s).

AzN1337c0d3r··on Microsoft researchers developed a hyper-efficient AI model that can run on CPUs
The original BitNet paper (https://arxiv.org/pdf/2310.11453)

  BitNet: Scaling 1-bit Transformers for Large Language Models
was actually binary (weights of -1 or 1),

but then in the follow-up paper they started using 1.58bit weights (https://arxiv.org/pdf/2402.17764)

  The Era of 1-bit LLMs: All Large Language Models are in 1.58 Bits
This seems to be first source of the confounding of "1-bit LLM" and ternary weights that I could find.

  In this work, we introduce a 1-bit LLM variant, namely BitNet b1.58, in which every single parameter (or weight) of the LLM is ternary {-1, 0, 1}.

That’s how it works. Legally they are the ones who authorized the tow through their contract.
AzN1337c0d3r··on Shadow credit score could decide whether you get an apartment
I've sued a landlord because their contracted towing company illegally took my car.

I won that case and got my towing fees back but I guess there's a stain on my record now even though this is really the landlord's fault for picking a shitty towing company who can't even follow state non-consent towing laws.

AzN1337c0d3r··on Whoever invented USB-C deserves a Nobel Prize
> Re-asserting: no, you do not need special cables for USB-PD. If a USB-C cable can't do 20V 3A, it's broken & out of spec & not USB. You're wrong & USB-C & the Type-C connector in general does not deserve this baseless & incorrect slander.

USB-C spec doesn't require cables to support PD. You're wrong.

https://www.reclaimerlabs.com/blog/2017/1/12/usb-c-for-engin...

"Even without supporting USB Power Delivery, it is possible to get as much as 15W through the USB connector. VBUS is still limited to 5 Volts, but the current can be as high as 3 Amps."

AzN1337c0d3r··on Whoever invented USB-C deserves a Nobel Prize
> All USB-C cables do PD. They all do 20V 3A. ALL OF THEM. This is wrong. What FUD.

No you are the one who is wrong. Nothwithstanding optical TB3 cables which can't even carry power, there are a large number of USB-C cables that only do 5V 3A on Amazon such as this one:

https://www.amazon.com/AmazonBasics-USB-C-Cable-USB-IF-Certi...

> There's no mode other than 40Gbps that is official, from what research I've done. But I do see some cables that list as 20Gbps. To me, this seems like a spec violation, but I could be wrong.

https://en.wikipedia.org/wiki/Thunderbolt_(interface)#Thunde...

Intel shipped at least 2 controllers that uses PCIe 3.0 x2, which only allows 20 Gbps.

Here is a CERTIFIED TB3 cable only capable of 20 Gbps:

https://www.amazon.com/Certified-Cable-Matters-Thunderbolt-U...

> In practice, nearly all TB3 cables are 40Gbps capable. They will almost completely certainly run USB 3.2 Gen 2x2 more than fine and will run DisplayPort Alt Mode more than fine. They'll do great.

No they won't. Some don't even support USB 3.0 (5 Gbps), especially if they are longer than 0.5m.

https://tidbits.com/2017/08/23/how-some-thunderbolt-3-cables...

"Instead of carrying up to 5 Gbps of USB 3.1 Gen 1 data, these active Thunderbolt cables throttle down to USB 2.0 speeds, offering about one-tenth as much throughput."

AzN1337c0d3r··on Whoever invented USB-C deserves a Nobel Prize
> #3 - the only way to buy the most capable USB-C cable is to give up altogether with looking for a USB-C Cable and to just buy a Thunderbolt 3 or 4 Cable, which isn't even USB!

The most capable USB-C cable isn't just a TB3 cable.

TB3 cables doesn't guarantee USB 3.2 Gen 2x2 support. Nor does it imply USB PD support. Also, does not guarantee Displayport Alt Mode support.

AzN1337c0d3r··on Apple’s Newest OLED Supplier
Yup I was able to reproduce it by displaying a high contrast checkerboard pattern for 2 minutes.

After I returned the 2nd laptop, I started opening the laptop in store to check for the issue and went through 4 more additional laptops before I got the Samsung display.

A couple of months later, in their repair catalog, Apple apparently created a new part number consisting only of Samsung displays and started replacing with a Samsung screen for all repairs.
