Ah, that explains this patchset that was submitted to the Linux kernel today
"KVM: s390: Introduce arm64 KVM"
"By introducing a novel virtualization acceleration for the ARM architecture on s390 architecture, we aim to expand the platform's software ecosystem. This initial patch series lays the groundwork by enabling KVM-accelerated ARM CPU virtualization on s390....."

IIRC Qualcomm smartphone SoCs have always run some kind of hypervisor, I believe it's to allow partitioning of the CPU cores with the modem/DSP.
They used to (mid-late 2000s) use an L4 derivative ("REX"?), with the more recent chips (including the 'X' series for PCs) using their homegrown "Gunyah" hypervisor (https://github.com/quic/gunyah-hypervisor)

I have a similar Windows Arm64 machine (Lenovo "IdeaPad 5 Slim"), RDP into it works OK.
There is one issue I ran into that I haven't on my (self-built) Windows desktops: when Windows Hello (fingerprint lock) is enabled, and neither machine is on a Windows domain, the RDP client will just refuse to authenticate.
I had to use a trick to "cache" the password on the "server" end first, see https://superuser.com/questions/1715525/how-to-login-windows...

Aside from the changing pint glass color and level, the Sky set top box / decoder, will also overlay the subscription ID at random intervals and locations.
I don't know if Sky does it, but Foxtel in Australia, in addition to the pint glass watermark, have a separate set of channels for public venues, which have different ad breaks/content to residential subscriptions. (https://www.foxtelmedia.com.au/foxtel-media-network/fox-venu...)

The Cypress chipset used to be a Broadcom product. Broadcom decided to sell the 'IoT' side of their WiFi/BT product line.

dsl (Dmitry) is the main developer behind the DPAA2 drivers for FreeBSD and he's done a fantastic effort so far. Myself and Bjoern (bz) have also written bits of it.
The performance has improved compared to how it was a year ago (e.g struggling to get 400mbps throughput) but there are some severe issues in -CURRENT :( I believe dsl is trying to get them fixed by 14.0-RELEASE.

No, we haven't bought any ASKs. We have worked with them on a DPDK project and they were quite helpful when it came to debugging difficult bugs with it.
Improving the routing performance in Linux is near the top of my TODO list, however. XDP is one candidate (see https://forum.traverse.com.au/t/vyos-build-my-repo/181/5 for some results) and using the LS1088's AIOP is another possibility.

Hi, I'm the person behind the Ten64.
Ten64's have been shipping for a while now, though you are best to ask in our support forum: https://forum.traverse.com.au/ . We haven't posted much on Crowd Supply as it's a very manual process to get stuff up on there.
I'm not too familiar with TrustZone, but I'm not aware of any limitations in the secure world. I haven't tried OP-TEE or any similar secure world firmware' simply as no one has asked for it.
You can see all our firmware components here: https://gitlab.com/traversetech/ls1088firmware

It's part of what's called the Universal Service Obligation (USO) for which Telstra (the dominant carrier) is responsible for delivering:
https://www.infrastructure.gov.au/media-technology-communica...
The money comes from a levy on telecommunications carriers (Telstra included, but also most of it's competitors). There was a bit of conjecture in the media that the "free" payphones were really being paid for by the other telcos, once the money Telstra contributes is discounted.

In Australia (Afterpay's home market), credit card merchant fees are tightly regulated (<1% for most transactions AFAIK), so 'cash-back' offers like the US don't exist.
Airline/Frequent Flyer point conversions similarly got nerfed, so much so it's better to cycle cards (credit worthiness permitting) every year to get a point bonus up front (e.g 200K points for spending $X000 in the first 3 months) than trying to earn that amount.

Nice writeup.
Reminds me of a famous 'intentional buffer overflow' by AOL in 1999 to determine if the user was using a 'genuine' AIM client, this came after Microsoft had added an AIM client to MSN Messenger.

Intel tried this with the Quark core, which was discontinued in 2019:
Compare the Quark Core Block Diagram: https://www.intel.com/content/dam/support/us/en/documents/pr...
with that of the 486 (Figure 3-2): http://datasheets.chipdb.org/Intel/x86/486/manuals/27302101....

I cleaned out a MBP of similar age while replacing the battery. There was quite a bit of dust trapped in the CPU fan, as well dried out thermal paste. Between new battery + cleaned fan + new paste it runs 'like new'.
(Unfortunately the dGPU on the machine appears to have developed a fault which might put it into retirement for good)

It's not as customizable under the hood as Home Assistant, but it's much easier to setup than HA.
Mozilla was attempting to market it to telcos and home router manufacturers as a IoT addon for a while (in competition with stacks such as Samsung's SmartThings) so they did do quite a bit of working making it usable for the average person.
This can be an unwelcome feature for some people, for example, if you want to have a vacation in the northern hemisphere summer season instead and/or maybe you don't have substantial family in Australia (or at least, those you actually want to see).
The auscorp reddit has a yearly thread on this issue: https://www.reddit.com/r/auscorp/comments/1mw6pqt/end_of_yea...
Those with school aged children might also want to save some of their annual for the mid-term/mid-year breaks as well. (Our academic years are aligned to calendar years)
