most AVR, automatic voltage regulators, won’t allow for rapid switching on and off.

Actively cooled UPSes, especially the ones that do more active double conversions, absolutely always have the fan on.

PCU: power conditioner unit?

VRU: voltage regulator unit?

While the UPS does have lots of upside, there are some downsides to consider:

Battery is a consumable, off gas venting, perhaps active cooling fan noise

oh interesting, what reasons make the ups safer?

It doesn’t sound like you need a UPS. It sounds like you needed automatic voltage regulator.

It’ll condition the power so it’s clean, and if it’s not clean it’ll cut the power off.

Many good UPS’s have a voltage regulator built in, but then you have the hassle the battery and everything. Up to you depends on what’s easier to find for you locally

I just finished this, yes it took me a month.

I found his literary style, very compelling, it was a fun read.

I found his predictions while interesting, not very clairvoyant. BeOS is sadly no longer with us.

I did like his tie-in to the Church of the simulation at the end, though this predates the official organization of such an church.

I think it was a thought-provoking essay, I disagreed with some aspects of this predictions, especially around what a monopoly is. It’s thought-provoking. It’s a good read. It is not gospel

He did talk about hacker culture, and anybody being able to fix anything, but was not able to make the connection between BeOS and proprietary license and Linux with an open license. The death of BOS followed one year from the creation of this essay

If you want a hands off linux experience

• ChromeOS
• AndroidOS

Linux with packages, specifically debian with packages. It’s fine and I’m happy it exists,

but… if your a security researcher, political dissident, hacker, etc you should be using Qubes inside of which you can run this debian distro if you want. you could even run Kali, and parrot at the same time!

https://en.m.wikipedia.org/wiki/Parrot_OS

Parrot OS is a Linux distribution based on Debian with a focus on security, privacy, and development

You misspelled Qubes

Then you can game no problem.

Pass through the GPU to one VM.

Qubes is unique

You could 100% play games on qubes if you have two graphics cards, or a integrated graphics on the CPU, and then have the GPU dedicated to a specific VM.

However, at that point, you might as well just use moonlight and sunshine and stream your game over the network.

Sunshine can run inside of a VM it just needs access to a GPU.

3d acceleration in qubes is very experimental. maybe not the best for gaming. You can do it, but your going to be elbows deep in virtio configurations

https://www.qubes-os.org/faq/#users

We do not provide GPU virtualization for Qubes. This is mostly a security decision, as implementing such a feature would most likely introduce a great deal of complexity into the GUI virtualization infrastructure. However, Qubes does allow for the use of accelerated graphics (e.g. OpenGL) in dom0’s Window Manager, so all the fancy desktop effects should still work. App qubes use a software-only (CPU-based) implementation of OpenGL, which may be good enough for basic games and applications.

For further discussion about the potential for GPU passthrough on Xen/Qubes, please see the following threads:

• GPU passing to HVM
• Clarifications on GPU security

Xen, The backbone of qubes, is One of the very few microkernels that is widely deployed. It’s extremely efficient. It only does the minimum amount of work necessary to dispatch resources to different virtual machine guests

So comparing a VM running on a dedicated microkernal hypervisor like qubes, compared to QEMU or KVM which requires a monolithic kernel, it’s going to be much more efficient.

But, when you start talking about the full desktop experience, with a window manager and mice and keyboards, and a guest VM, and a VM to run the desktop, and a VM to run the USB for the mice and keyboard, and a VM for the network stack, and a VM for the firewall… It’s less efficient compared to a system running a single QEMU VM with a monolithic kernel, and everything handled with a traditional monolithic operating system.

It depends on your use case, what you want to optimize for, quite frankly if you don’t care about segmentation and security qubes is probably going to be too much friction for you.

It’s using Xen, it has amazing hardware support

I’m in the same boat, just under 3PiB

This is a big f****** deal. If you get kernel access to a system, which is not uncommon, you can install a persistent back door that subverts the rest of the system forever. That’s huge. It does not require physical access, requires kernel access… different things

Steam games that ask for admin privileges, a USB stick that boots, normal virus infection that can never be uninstalled,. persistent RAT…

Depends on your use case there are multiple factors that guide internet use cases

• Latency - how fast
• Bandwidth - how wide/much
• Loss - how much data is lost, or how much data needs to be sent again

Gaming: latency, loss

YouTube/movies: bandwidth

Video chat/voice chat: latency, bandwidth

Remote desktop/game streaming: latency, bandwidth, loss

Web browsing: bandwidth, latency

DNS latency can be a multiplier for browsing the web, a website can include artifacts from other websites, which then can include other websites, which then can include other websites. Each one of those would require another DNS lookup, and round trip time to the website itself etc. however, DNS was architected for local caching, so only the first lookup should be slow, and then afterwards you should keep that DNS information for future lookups so it’s not going to feel too bad once you’ve warmed up the cache

Rule of thumb: under 100ms feels fine, over starts to feel a little sluggish. Over 300ms and you change your behaviors, and you really feel it.

Forget the iron throne, iconic but a distraction.

White walkers take total control north of the Wall, and the nights watch/king in the north are having SERIOUS issues keeping the wall in good repair, some white walkers are able to get south of the wall and take over northern castles and strong holds… maybe we introduce a mechanic where the ice-zombies are slower and weaker in warm weather, so this initial incursion is a PROBLEM but not the end of the world, but as winter comes, this becomes more urgent.

Snow/Night Commander hears from the meisters that there are dragons in Essos, and that Fire Dragons are a great counter to the white walkers… Things are dire, he sends ravens/and proxies to Essos to BEG for a dragon but this is ignore/rebuffed since the Dragon queen is perfectly busy in Essos Thank you very much.

After HEAVY losses, HEAVY, perhaps a breach of the wall, Snow goes in person to Essos to beg for dragons as the only possible way to save Westeros. Bran/Mr. Whispers know he is a targarian and do some subplots to prevent them from finding out, plot, plot, plot, In Essos the queen meets snow, they have conflict, dragon fire can’t kill Snow, they both discover they are related… Maybe Snow has a better connection/control of the dragons, something to make the Queen to consider him a huge threat. Queen of Dragons gives Snow a single dragon to help with the wall, and sends him away so she can focus on Essos plots with the promise that Snow will help her claim revenge on those who killed her Dad (lannisters).

Dragon is pregnant, but nobody realizes, goes to the wall, fights, gets converted to a Zombie dragon and lays eggs, the last possible dragon eggs, which the Dragon Queen must come and rescue before they are born (Ice / Zombie dragons threaten Essos as well as Westeros)…

Now we finally have a motivated reason for the Dragon queen to abandon her empire on a side quest, which puts her and her other dragons in Westeros so she can be part of the winter battle, melt the iron throne, etc…

(I just finished a rewatch of the show, so I’ve got some ideas in my head still)

Essos is clearly the prize, westeros is a side show… like the UK vs Europe… But if you want to conquer Essos you can’t leave your western flank open, you have to secure westeros before you can move your military eastward.

If her arc is freeing more slaves, and starts to look east, she has to wrap up the West. We could motivate it by showing diminished supply lines going east, and the logistical trouble going east. Have some harassment from the iron Islands, some piracy, continue to assassination attempts from the Lannisters, The iron Bank refusing to bend the knee - and funding competition, motivating a need to secure the West and put in place a hand of the queen so she can focus on the east. I think you could sell it as a good story

Update - I now realize, The Dragon queen is in Slavers bay / Dragon’s bay, in the freaking middle of Essos, so everything I wrote above doesn’t apply. There is no good reason to leave her empire and travel HALF the world away, skipping all these other kingdoms and leaving your rear open, with huge logistics and supply issues. Abandoning a perfectly good, and GROWING, power-base to secure a side-show because its where they killed your dad doesn’t make sense, ESPECIALLY because the targarians only went to westeros “recently” and they are originally from Essos anyway.

She should expand her free slave empire slowly westward, and eventually secure a strong path to Westeros before the Dragon throne plot can happen, other than revenge, there is no urgency in recapturing Westeros

It was the open standard, then Google broke it and introduced Chromecast.

And they’ve polluted the wording so that Chromecast means both the device, and the protocol, etc etc

I look forward to seeing what they rename the streaming protocol to. Maybe it will still be called chromecast
