I can't tell if any of this gives you more access than the normal http admin interface.

On the other hand, my local qwen model (3.8-flash-next) was trying to convince me that the eMudhra CA thing is no big deal since you need to be "positioned correctly" (eg: any wifi network) to be able to MITM, and most of the IOT devices would have patched stuff by now.

Just to close the loop, AXI bus[1] refers to a very common implementation, in the gateware/verilog, of a MIMO.

Op probably missed https://github.com/FrameworkComputer/FrameworkDebugger#jspi. Though, the connector is not populated for cost reasons.

Otherwise, I agree with the author, this is a pain.

Are you sure the models did not have your exact solved proof already in their dataset?
Re:The Serial TTL connector we deserve on Saturday May 09, 2026 @10:30PM (#48080442)
One thing that i see often: just because both your debug cable and your target runs at the same voltage (eg: 3.3V), doesn't mean it's safe to plug them together. You could easily have a situation where your target or your debugger is off, so at that point you're powering the off thing through the uart pins (the esd diode on the pin).

The safest thing is to have a 4th vref/vccio pin, then the debugger should power its tx signal from that pin, at whatever voltage it's at. Same for the RX pin, it's not nice to have a pullup to a certain voltage when the target is off.

you should try vulkan instead of rocm. it goes like 20% faster.
I think you're overstating this. The "handshake" is purely 2 simple resistors correctly installed. The problem is a lot of folks do it wrong for various reasons, most likely never testing with anything more than type a to type c cables.

Ah yes, because "How now the smart flies take the new time beyond new time where new times come." is so much easier to remember than "2001:db8::1".

I want my time back :D . Here I was picking things that i liked the most, and it gave me Ubuntu Mono, a font I already have selected in my editor.
Yeah, it's worse, half of the devices on that list are peripherals that cannot be flashed with any firmware.

I'd be curious to know more about the switch reverse engineering. What was the ultimate goal for this password.

I keep hearing podman is better, especially for local setups. Does anyone know any podman cheatsheets similar to this or is it pretty much s/docker/podman?

I have been doing a couple of tests with pytorch allocations, it let me go as high as 120GB [1] (assuming the allocations were small enough) without crashing. The main limitation was mostly remaining system memory:

    htpc@htpc:~% free -h
                   total        used        free      shared  buff/cache   available
    Mem:           125Gi       123Gi       920Mi        66Mi       1.6Gi       1.4Gi
    Swap:           19Gi       4.0Ki        19Gi

You're missing any AMD stuff, I can run a quantized deepseek r1 671B on 4 framework desktops, yet it's "insufficient" for 10 Nvidia gpus.
Re:Show HN: I made a 3D printed VTOL drone on Tuesday June 10, 2025 @10:59PM (#44243780)
Shameless plug: https://aliptera.com/

Tilt-rotor on all 4 motors with an extra twist: the wing shape adds to the lift in vertical mode, so you can use smaller motors, so they're more efficient even in horizontal mode.

> Traditionally, programs will place their code into non-writeable memory, and store variable data in memory that is writeable but not executable. And that's definitely the safer way to do things, but we can't be bothered with all that.

Woah, I have a feeling this does something even more. If the program modifies its own instructions, the kernel will probably save those modifications in the file too.

> sudo mkdir /rescue/boot

> sudo mount /dev/nvme0n1p3 /rescue/boot

This is a little extra. What you can generally do is immediatelly after chroot just run 'mount -a' to mount everything from the chroot's fstab. The empty `/boot` probably already exists.

There is!

arch-chroot [1], despite its name pretty much does all the `mount -t proc` stuff the post says. It's also available on other distros like debian [2]. I have used it in the past to chroot into fedora as well.

It can go higher actually, just that when I setup my test devices I had a "ought to be enough for everyone" moment when typing `options amdgpu gttsize=110000`. I guess this number spread too far, heh.

I did find the community around those projects (MisterFPGA) to be rather weird, so I understand a little where he's coming from.
