If I understand you correctly: 1) The box I'm thinking of using has a CPU that is an Intel core i5-7500. It has 4 cores running at 3.4GHz, and It has 24GB RAM. The OS is Debian 6.1.55-1 (2023-09-29) -- stable/bookworm. 2) The Virtualbox documentation (but not virtualbox itself?) is available in Debian Sid (but only Sid?) 3) Does the documentation (either from Virtualbox.org, or from Debian Sid) cover installation and use of Virtualbox under Debian? 4) How do I find out if it has virtualization/svm enabled in the firmware? If it does, would I be better off with KVM/QEMU, or Virtualbox? Thanks very much! Rick

NPU - Neural Processing Unit - chip designed for AI use. NPU in this context is not actually the Big G. The leader on small system NPU is actually Nvidia and their Jetson product et al. In my case Rockchip has added a processor they style an NPU to their newer SOC products. What that boils down to is one or more units that can perform very fast vector arithmetic operations at various precisions. These can be used to process data in neural networks as well as conventional signal/image processing. In my case I have a Rockchip RK3588 that can do 6 TOPS (Tera operations per second) using three independent NPU cores. You can use these to do neural network work or anything else that vector arithmetic is helpful with such as image processing or signal processing. These NPU units will become more and more common and their use will be adapted by many current applications to speed operations for signal and image processing. However, at this stage, though they are also be able to do Neural Network processing, the really intense NN applications such as Large Language Models (e.g. GPT) are probably out of useful reach. That stuff is done in the cloud with dedicated NN processors (which may be Nvidia based?)

Re: Documentation for KVM/QEMU?
Maybe the op wqould like to test aqemu, which is a graphical frontend for qemu and it might be easier for him to configure. In the comparision of aqemu (with using kvm) and VirtualkBox and Virt-Manager my feeling was, Virtualbox the slowest and both Aqemu and VirtManager faster. The latter two are were looking both even fast. However, virt-manger IMHO still is not very user friendly, especially for beginners, and also its documentation is not much at the moment. But please be respectfull (or is considerately the correct idiom?): virtmanager is rather new and has not many people involved, so it might become better in the future. Virt-manager has great potential. Best regards Hans

Debian 12 Gnome - No notification for available updates
Hi Debian users, I have a computer running Gnome 43.6 that does not show notification when updates are available. It was working a few months ago, but can not tell when it stops working. Questions: - How can I bring back available update notifications? - Do you think it deserves a bug report on Debian bugtracker or upstream? Some details: - The computer was installed with Debian 11 and manually upgraded to Debian 12, and currently runs Gnome Software 43.5-1~deb12u1. - I confirm that /usr/bin/gnome-software --gapplication-service is started automatically when I open a session, which in turn runs PacakeKit to get update information (as seen with pkmon). - apt list --upgradable lists many available updates. - I do not use a metered connection. - I do not have any fancy settings in dconf (I only disable automatic download): $ dconf dump /org/gnome/software/ [/] check-timestamp=int64 1691236134 => Sat Aug 5 13:48:54 CEST 2023 download-updates=false first-run=false install-timestamp=int64 1661718901 => Sun Aug 28 22:35:01 CEST 2022 online-updates-timestamp=int64 1675285379 => Wed Feb 1 22:02:59 CET 2023 update-notification-timestamp=int64 1698304770 => Thu Oct 26 09:19:30 CEST 2023 - When I start Gnome Software, it displays the number of updates on the top. - Notifications are enabled: $ dconf dump /org/gnome/desktop/notifications/application/org-gnome-software/ [/] application-id='org.gnome.Software.desktop' enable=true - I have just created a new user on the machine, member of the sudo group, but it does not get any notification either (but updates are automatically downloaded) Regards, Yvan OpenPGP_signature.asc Description: OpenPGP digital signature

And the reason it isn't available in testing is that there's no viable way to provide security support for it in stable, and testing is supposed to only contain things that are candidates to become part of the next stable release. Once upon a time it was made available in each new testing and then removed before the stable release (and that's how I was running it, for a fairly long while), but I remember a discussion which led to the decision that that was not an appropriate practice given relevant policy. I don't remember with confidence offhand exactly *why* it was decided that it isn't viable to provide security support for VirtualBox in stable. I remember it had something to do with how upstream provides patches for security fixes, but I don't remember whether it was "upstream doesn't provide split-out patches per fix, but only one massive patch when they make a new VirtualBox release" or something more to the effect of "the license upstream releases its code under does not permit taking changes out separately like that". -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.

As I said, I think you are creating a false dichotomy between 'metaphorical' and 'precise'. Possible antonyms would be 'literal' and 'imprecise', respectively. Regarding usage, I think that the horse has bolted. The people using 'folder' are probably in the majority now, in particular if we think of all those who never end up on the command line. So if someone wants to sell me snake oil, he or she will definitely need some more dazzling jargon than 'folder'. -- This signature is currently under constuction.
