Google is certainly planning on it being viable.

They’ve been merging RISC-V support in Android and have documented the minimum extensions over the base ISA that must be implemented for Android certification

ozymandias117 ,

Yeah, that’s bizarre. I’d never have guessed /home was created by tmpfiles

ozymandias117 ,

There are reasonably frequent rebuilds of basically all packages as new versions of the compiler, gcc, come in

ozymandias117 ,

The RK3588 is pretty nifty, and is the first Mali GPU (610) where ARM themselves have contributed the firmware upstream and have helped with Collabora with Panfrost development

Bleeding edge, still, but kernel 6.10 and Mesa 24.1 have GPU support

HDMI TX and DSI/CSI are still in-progress

AMD has preemptively dropped support for Windows 10 on its new Ryzen AI 300 Series chips (www.tomshardware.com)

In another attempt to convince us that "AI PCs" are somehow fundamentally different from the PCs we're already using, AMD has officially dropped support for Windows 10 from its new AMD Ryzen AI 300 Series platform. This can be observed by glancing at the official AMD Ryzen AI 9 HX 370 specs page, which now only lists 64-bit...

If your motherboard supports it, it’s really easy

Ensure IOMMU is enabled and run the little script in section 2.2 to see if you can isolate the graphics card

https://wiki.archlinux.org/title/PCI_passthrough_via_OVMF

After that, you can do everything in the virtual-manager GUI

ozymandias117 ,

I’m working off the assumption you are using one GPU for the host and one for the guest

The guest one is permanently blacklisted on the host, and you can select the passthrough settings in the GUI

If you’re dynamically detaching the GPU, my statement was incorrect

Apple is bringing RCS to the iPhone in iOS 18 | The new standard will replace SMS as the default communication protocol between Android and iOS devices (www.theverge.com)

The long-awaited day is here: Apple has announced that its Messages app will support RCS in iOS 18. The move comes after years of taunting, cajoling, and finally, some regulatory scrutiny from the EU....

If you’re relying on iMessage for privacy, ensure you and everyone you’re messaging have gone to iCloud settings and enabled “Advanced Data Protection”

ozymandias117 ,

I enjoy that they literally did. The article says the OTA update is just to ignore a hardware sensor

Which begs the question, why was that sensor needed originally?

ozymandias117 ,

The design/manufacturing of a chip is separate from the lithography machine itself

This is the first lithography machine Russia has built. They’d be getting the 90nm ones probably from ASML

ozymandias117 ,

Which is why they’re trying to make their own now

ozymandias117 ,

System on a chip. Think like a Qualcomm or Samsung processor, or the new M line from Apple

ozymandias117 , (edited )

The comment over on hackaday pointing to it being bricked possibly being down to font licensing is funny if true

ozymandias117 ,

For most intents and purposes

SoC is from the embedded system development world - as more and more coprocessors were being put into the same chip to consolidate board space and power efficiency, it wasn’t “just” a cpu - it had the CPUs, GPUs, DSPs, and other coprocessors in one

x86 has moved a lot closer to this architecture over the years, but you still generally have a separate chipset controller on the motherboard the CPU interfaces with

ozymandias117 ,

I haven’t looked that closely at laptop CPUs

My guess would be partially because there are fewer possible interfaces, and they’re directly connecting the CPU to a separate Ethernet/WiFi MAC, USB hub controller, and audio DSP rather than having a separate chipset arbitrating who’s talking to the CPU and doing some of those functions?

ozymandias117 ,

I can’t say for all of them, I just knew that e.g. the z790 chipset still ran the ethernet phy, audio dsp, SPI, their version of TrustZone, etc through the chipset

https://www.funkykit.com/wp-content/uploads/2022/10/intel-z790-chipset-diagram.jpg

If you have the block diagrams for the laptop ones, I’d be curious

ozymandias117 ,

I’m so curious to see how a Qualcomm gambit plays out for Microsoft.

With the ethos at Qualcomm being support a chip for 1 year, then move on, I have trouble believing they’ll update the drivers for a major windows release

Google browbeat them for nearly 10 years, and then ended up going with the majority Samsung designed chip called Tensor just to compete against Apple in years of updates

CEO of Google Says It Has No Solution for Its AI Providing Wildly Incorrect Information (futurism.com)

You know how Google's new feature called AI Overviews is prone to spitting out wildly incorrect answers to search queries? In one instance, AI Overviews told a user to use glue on pizza to make sure the cheese won't slide off (pssst...please don't do this.)...

ozymandias117 ,

In this case, it seems pretty likely. We know Google paid Reddit to train on their data, and the result used the exact same measurement from this comment suggesting putting Elmer’s glue in the pizza:

https://old.reddit.com/r/Pizza/comments/1a19s0/my_cheese_slides_off_the_pizza_too_easily/

And their deal with Reddit:
https://www.cbsnews.com/news/google-reddit-60-million-deal-ai-training/

ozymandias117 , (edited )

I literally linked you to the Reddit comment, and pointed out that Google’s response used the same measurements as the comment

Are you an LLM?

ozymandias117 ,

It’s also funny to use “giga” in the marketing when everyone else is dealing with petabytes

ozymandias117 ,

A “fun” one I ran into was all our tests passing on my desk, but failing in the test farm

After a month, we realized that having an HDMI cable plugged into the unit was corrupting the SD card due to a memory overwrite in the graphics stack

ozymandias117 ,

They also use risc-v since 2017

Xen is a type 1 hypervisor, KVM is a type 2 hypervisor

It runs on the bare metal itself as dom0

ozymandias117 ,

LXC is for containers, rather than virtual machines

I was just saying “obsolete” isn’t a good description; All three still have uses depending on your goals

LXC is probably better for most people, and I think Podman is one of the best rootless container options

ozymandias117 ,

pack our plans with value and build out the industry's best 5G network

I’ve generally needed to disable 5G on their network because it was slower than LTE. 5G has only been useful in places they didn’t have coverage before in my experience

ozymandias117 ,

I tested where I happen to be, and T-mobile 5G was 7 Mbps and LTE was 34 Mbps

I’m not saying 5G can’t be better, but it’s rarely been better on T-mobile for me in about 5 different states in the US

ozymandias117 ,

The issue is that “5G” is three different bands in one name

In the places where it’s low-band 5G and LTE is also available, LTE is significantly faster

If you’re in the downtown of a major city, high-band “mmWave” 5G will be faster

ozymandias117 ,

Buy it for life

ozymandias117 ,

Huh?

32-bit ARM and x86 were both from 1985…

It did take ARM a lot longer to make 64-bit work

ozymandias117 ,

What’s up?

ozymandias117 ,

It’s also that “Shutdown” doesn’t shut the computer down. It puts it into a sleep mode so it will “boot” faster next time

The hibernation mode has more wake up sources than if it was actually off

ozymandias117 ,

It depends on the wake up source you’re talking about, but, yes

Your BIOS can configure the hardware, then Windows gets to modify parts of the configuration through ACPI

ozymandias117 ,

Most companies group MENA separately. They must sell so few devices there that they don’t want to show the numbers separately

ozymandias117 ,

I can’t speak for Apple, but every company I’ve worked for has split their region reporting as soon as one of the traditionally smaller regions gets big enough

It creates hype and a boost to their stock price

ozymandias117 ,

If it used to be a valid website, and is now a scam, that’s a mole worth whacking - even if they’ll try again with a previously unknown url

ozymandias117 ,

It’s ubiquitous because it was added for free to Office 365, so companies would use it instead of its competitors

Microsoft changed that for new customers a couple weeks ago and it’s now a separate subscription

The standard make it free until it’s ubiquitous then start charging for it

ozymandias117 ,

The push towards large vehicles was due to the fact that they used a truck chassis, and were exempt from safety and emissions requirements of a “car”

ozymandias117 ,

The one they use at my work is extra silly, as it adds an extra email header saying it’s coming from a phishing campaign

After announcing increased prices, Spotify to Pay Songwriters About $150 Million Less Next Year (www.billboard.com)

When Bloomberg reported that Spotify would be upping the cost of its premium subscription from $9.99 to $10.99, and including 15 hours of audiobooks per month in the U.S., the change sounded like a win for songwriters and publishers. Higher subscription prices typically equate to a bump in U.S. mechanical royalties — but not...

ozymandias117 ,

As bad as Epic is, probably worse…

Even though Bandcamp was profitable the new CEO said this after buying it

the financial state of Bandcamp has not been healthy

So they’re probably looking for any way to cut costs.
They fired half of the staff on day 1, including anyone who tried to unionize

ozymandias117 ,

fast.com is pretty good, too.
No nonsense, and run by a company renowned for server throughput optimization, so it should rarely be on their end if it’s a slow result

ozymandias117 ,

If it increases in pressure every time, I’m now curious how many times you need to close the trunk to cut a finger off

ozymandias117 ,

The quote of “removing RISC-V from generic kernel images” makes a lot of sense

It only kind of works on arm64 right now, trying to add a whole new ISA seems rushed

If they make exceptions for customized kernels for other architectures for now, that seems fine

ozymandias117 ,

They made so much more that they can afford to keep spending their lawyers time on it

All three major carriers vowed to appeal the fines after they were announced today

ozymandias117 ,

It’s been known for a long time that they cheat on benchmarks

https://www.anandtech.com/show/7384/state-of-cheating-in-android-benchmarks

They specifically detect benchmarking tools and run at a frequency they can’t maintain for the length of the benchmark

ozymandias117 ,

It’s also always been strange to me, because the default response to any issue with Windows when I used it was “just reinstall”

Even at work, my laptop got kicked off of Active Directory - they tried to fix it for a couple days and ended up with“we have to reimage it”

ozymandias117 ,

I was curious too, so I tried it in a virtual machine

It half installed sysvinit, systemd failed to get fully removed, and apt gave up due to too many post-install errors

The reboot threw me into an init that asked for me to specify the runlevel (since there wasn’t anything in init.d)

I guess they didn’t understand the difference between that question and a logged in shell

My guess before trying it was that they somehow got stuck in Grub’s shell

ozymandias117 ,

(As the tester above) It is a broken state

It failed to install the initscripts package because apt bailed out

apt —fix-broken install got you a little closer, but the screenshot didn’t say they tried that

My bet is this worked when systemd was first introduced, but since there’s not much use for it now, and sysvinit is deprecated, it just doesn’t accidentally work anymore

ozymandias117 ,

You can’t - it’s just asking what runlevel to launch, and there are no files for any runlevel

You’d need to add init=/bin/sh through grub at that point

ozymandias117 ,

I didn’t after breaking it and rebooting

I restored the snapshot from before breaking the system and tried to see what would happen if I didn’t just reboot after apt bailed out
