We all know how it's possible for a guest VM to access various host functions by accessing a PCI device, right? When KVM traps an access to this fake PCI, QEMU emulates the device, which allows packets sent, console updated, or whatever. This is called "virtio".

NVIDIA took it a step further: they have a real PCI device that emuilates QEMU. No joke ( Read more... )

They pushed the "You're one of a few experts invited to answer" notifications for a long time - maybe a year, I don't remember. When I had enough and started to capture them with the intent of mockery, they stopped. So sad. Here's what I got ( Read more... )

Because FreeCAD was such a disaster for me, I started looking at crazy solutions, like exporting STEP from OpenSCAD. I even stooped to looking at proprietary alternatives. First on the runway was SolidWorks. If it's good for Mark Serbu, surely it's good for me, right?

The first thing I found, you cannot tap your card and download. You have to ( Read more... )

The other day I was watching a video by Rich Jones about Fedora on RISC-V. In it, he mentions off-hand that CentOS Stream 10 inherits from Fedora 40.

I don't know how that happened anymore, but previously someone made me think that 1. there will be no more numbered releases of CentOS, which is why it is called "CentOS Stream" now, and 2. CentOS ( Read more... )

The only way to obtain STEP from OpenSCAD that I know is an external tool that someone made. It's pretty crazy actually: it parses OpenSCAD's native export, CSG, and issues commands to OpenCASCADE's CLI, OCC-CSG. The biggest issue for me here is that his approach cannot handle transformations that the CLI does not support. I use hull all over the ( Read more... )

What do you think this does:

class A(object):
 def aa(self):
 return 'A1'
class A(object):
 def aa(self):
 return 'A2'
a = A()
print("%s" % a.aa())

It prints "A2".

But before you think "what's the big deal, the __dict__ of A is getting updated", how about this:

class A(object):
 def aa(self):
 return 'A1'
class A(object):
 def bb(self ( Read more... )

Problem:
When copying from tmux in gnome-terminal, the text is full of whitespace. How do I delete it in gvim?

Solution:
/ \+$

Obviously.

This is an area where tmux is a big regression from screen. Too bad.

Speaking of S3 becoming strongly consistent, Swift was strongly consistent for objects in practice from the very beginning. All the "in practice" assumes a reasonably healthy cluster. It's very easy, really. When your client puts an object into a cluster and receives a 201, it means that a quorum of back-end nodes stored that object. Therefore, for ( Read more... )
