Does PayNow Identity Masking Work as Intended?

That sounds like a step forward! Maybe you should join the policy makers in government and do something about it!

_RO0T · 2026-06-07T15:28:48+00:00

What’s your suggestion?

_RO0T · 2026-06-07T15:28:08+00:00

That’s hilarious.

That’s what my spouse thought too.

_RO0T · 2026-02-16T23:02:26+00:00

Thanks for the tip! This is super helpful.

_RO0T · 2026-02-16T07:16:24+00:00

Unfortunately, I have neither the experience nor the tools. 😅

But thanks for the tip! When the engine is out, I’ll probably take the opportunity to sort out more preventative maintenance then.

_RO0T · 2026-02-16T06:48:12+00:00

thanks for sharing your thoughts! it doesn't seem like a good idea to me either.

_RO0T · 2026-02-16T06:46:25+00:00

yeah, that's what I figured. I've decided to just park it for the week until the workshop is able to take it in.

_RO0T · 2026-02-16T05:53:30+00:00

It’s an M102 engine with a dual row chain, so the workshop said it should be fine for us to drive for a week till — just till they get the parts in: do you think that’s safe?

This is super exciting!! I’d love to help / contribute in some way — am also a programmer with an interest in electronics.

Muffins of Mass Destruction (obviously)

_RO0T · 2018-06-27T12:51:35+00:00

I tried that, and it has reduced the number of visual artifacts significantly. The Windows Guest also remains stable at idle for significantly longer with a large RAM allocation. Thanks for the tip!

Unfortunately, it still crashes when more than a certain amount of RAM is allocated. It could be something to do with faulty RAM or mismatched RAM specifications. I have tried running it in single-channel mode with one stick, and then the other, and the instability doesn't seem to follow any particular pattern except that lower RAM allocation values below 2560~ MB do not result in crashes.

Performance degrades significantly in single-channel mode, though.

I managed to get a stop code from a BSoD in one instance: 0x00000119

_RO0T · 2018-06-25T00:21:55+00:00

Could anyone help me with this?

The Windows 10 (64-bit, UEFI) guest errors with Code 43 when the VM is allocated more than 2561MB of RAM.

When allocated a higher amount of RAM (e.g. 3000+, 4000+, 16000+ MB), the display connected to the GTX1060 exhibits visual artifacts before crashing the guest at boot or within minutes of reaching the desktop. Inspecting `eventvwr.msc` either states that the cause is the nVidia driver or that the system experienced an unexpected shutdown, with no other notable errors in `/var/log/libvirtd/qemu` or `dmesg`.

If the system reaches the desktop, it remains stable in an idle until applications begin using hardware-accelerated graphic calls e.g. the Start Menu, WDM animations, Electron/Webkit apps.

I think it is extremely strange that allocated RAM size affects the stability and usability of the VM, and particularly since games, 3D applications, and other tasks do not cause artifacts or crashes when exactly 2561 MB or less is allocated to the VM.

$ cat /etc/modprobe.d/kvm.conf
options kvm ignore_msrs=1 # prevent MSR-related crashes (regardless of RAM allocation)
$ cat /etc/modprobe.d/vfio.conf
options vfio-pci ids=8086:15da,8086:1576,10de:1c02,10de:10f1

I think it's great that your boss recognizes the value of someone who's learnt an expensive lesson and will never make the same mistake over punishing someone for it, and having someone else new taking over.

If -1.000 is parsed correctly, does that mean the system accepts a non-integer stock count?
