Windows 11 24H2: “insufficient system resources” trying to login

I’ve talked about running a SAMBA Domain Controller before. It definitely has its ups and downs, but damn Microsoft loves being hostile to SAMBA.

I have deployed multiple computers with Windows 11, including the latest 24H2 update, but we recently had a specific Device, a Microsoft Surface Pro 9 to be precise, which received the 24H2 update “naturally” via Windows Update.

As soon as it rebooted, the user ran into an issue.

Upon trying to login, the user was greeted with the following error:
“insufficient system resources exist to complete the requested service.”

Correct password, incorrect password, no password – it didn’t matter. Domain users immediately showed the error. I was, however, able to login as a local user.

Spy Craft of the 22nd century: Quantum Entanglement

I’m not a I’m not a quantum physicist, nor a computer scientist. But Microsoft released this video a few months ago which sparked a thought.

Microsoft & Photonic demonstrate distributed quantum entanglement

While they were quick to point out the obvious benefits of “teleporting” the quantum state, i.e. the computational results, from one pair of entangled qubits to another.

This quickly begged the question: given the hyper-advanced nature of supply chain attacks (see Israel planting explosives in the pagers of Hezbollah operatives, recently), could a nation-state simply take entangled qubits of an adversary’s quantum computer and see what it is they are working on at any given time? Further, could communications networks be compromised for real time ‘eavesdropping,’ so to speak? Perhaps not even internationally, but perhaps in an intelligence gathering platform akin to the NSA’s own PRISM program? If there is, according to some theories, no limit to the number of particles that share an entangled state, nobody would know if you simply “cloned” a few more, right?

Am I understanding that well enough? Or would it not be the Qubits that become entangled, and only the ‘data’ that flows through them?

I’m not the person to write the research paper on this topic. But I certainly hope someone out there will produce it – because I would love to read through it. Just an interesting thought I had with an eye on the future. Whether that future is 20 years, 50 years, or even further out is another question.

Ubuntu Linux CPU usage / CPU temperature high? Try this…

We have an Ubuntu based mini computer at which serves as little more than a network switch. CPU and other resource utilization should be next to nothing, but frequently this computer would have CPU temperatures around 80 degrees Celsius, and when you would watch the resource monitor the CPU activity was all over the place. Despite the computer only really showing a few percent of CPU usage, if you went toe the Resources Tab of System Monitor, the per-core CPU activity was all over the place.

As I mentioned, the computer in question is a simple network appliance that would never need to print, and upon closer inspection, it was the Linux “CUPS” Service. Once we disabled that, the CPU settled right down.
