Btw the CPU in the Lenovo P330 is an e-2174g. I also got an e-2274g.
- Comment on Small NAS home server woes 5 days ago:
I got a sff P330 Xeon with integrated graphics for ~$500 two years ago that includes case power supply etc. Far faster than an n100 and even lower power than if you added a GPU to an n100.
I just plugged in a kilowatt to check:
My Lenovo sff workstation running Plex idles at 15 watts- which is 90% of the time. Streaming 4k 52Mbs hevc (This Flash Gordon is my torture test that caused me to upgrade 2 years ago) it’s 18 watts! I was so surprised that I went back and unplugged the Ethernet thinking I put the killawatt on the wrong server.

What’s your budget? I’m a big fan of old Xeon servers.
- Comment on Self-hosting your own media considered harmful - I just received my second community guidelines violation for my video demonstrating the use of LibreELEC on a Raspberry Pi 5, for 4K video playback 6 days ago:
Was it YouTube or someone else that reported him? I think YouTube is fully automated so it blocked him and is ignoring appeal because of the previous complaint.
- Comment on Wikimedia Foundation's plans to introduce AI-generated summaries to Wikipedia 1 week ago:
I’m pro AI but absolutely fucking not.
The use case for AI is to summarize Wiki as an external tool. If Wikipedia starts using AI, it becomes AI eating its own tail.
- Comment on When a person follows you and watches your every move, it's called stalking. When companies like Meta do it, it's just called collecting user data. 1 week ago:
In the future, all Fridges will do it. You’ll have 10 brands to choose from but they’ll all collect your personal data and send it out via built in cell service.
- Comment on Whatever happened to cheap eReaders? – Terence Eden’s Blog 1 week ago:
He blames patents (Eink isn’t a patent troll) although Eink patents expired 7 years ago.
The problem is even without patents, the underlying tech of making the eink particles is hard.
- Comment on I'm looking for an article showing that LLMs don't know how they work internally 1 week ago:
I only follow some YouTubers like Digital Spaceport but there has been a lot of progress from years ago when LLM’s where only predictive. They now have an inductive engine attached to the LLM to provide logic guard rails.

- Comment on ICE Taps into Nationwide AI-Enabled Camera Network, Data Shows 2 weeks ago:
It’s your claim that Anonymous would do anything when they won’t and do it by AI poisoning that’s absurd.
If your initial claim was, “It would be a shame if someone hacked their local police.” it wouldn’t have sounded like you just watched Mr. Robot.
- Comment on ICE Taps into Nationwide AI-Enabled Camera Network, Data Shows 2 weeks ago:
This article says it is local cameras installed by local police that are being used for ice by the local police department.
Claiming anonymous could do anything about it by poisoning AI models is absurd. Then you call out the skeptic for watching too much TV?
Anonymous hasn’t ever done anything significant in 10 years They dos’ed Israel last year. Did it do anything? Was one less Palestinian killed?

Just a reminder that Epstein was killed when Trump was president. Trump’s attorney general was William Barr. Barr’s dad was very close friends with Epstein, gave Epstein his first job, and Barr’s dad wrote pedo scifi as a hobby.
- Comment on Dont call this number again, we uphold the laws of physics in this home 2 weeks ago:
I don’t get the, “obey laws of physics.” Variable focus reflective optics are a thing. Both by moving the mirror distance or by using fancy materials to change the curvature of the mirror.

You still don’t understand the links you are providing. Fuck, just read the English words even if you don’t understand the math.
“We aim to present reversible systems which lie on the border of solvability/integrability and chaos.”
The intro says it’s not chaotic but a function that borders on chaotic.
“We adjusted the precision in such a way that the true initial data and the result of this round trip did not differ by more than 10−3.”
Their function isn’t even reversible but only allows for an approximation of reversibility.
Conclusion:
“We have shown that there exist infinite families of rational maps which, at the same time, have positive algebraic entropy, present features of chaos, and are solvable.”
FEATURES OF CHAOS ISN’T CHAOS.
- Comment on [deleted] 2 weeks ago:
It’s implicit in the method. There also isn’t a definition of computability in the papers or Wikipedia because it assumes you have a basic understanding.
Chaotic functions require that you iteratively step through them because they aren’t closed form.
“For chaotic systems the evolution equations always include nonlinear terms,5 which makes “closed-form” solutions of these equations impossible—roughly, a closed-form solution is a single formula that allows one to simply plug in the time of the desired prediction into the equation and determine the state of the system at that time.”

I last wrote a paper on chaos in a mechanical system 35 years but I haven’t forgotten the basics.

'Robert L. Devaney, says that to classify a dynamical system as chaotic, it must have these properties:[22]
it must be sensitive to initial conditions, it must be topologically transitive, it must have dense periodic orbits. " en.m.wikipedia.org/wiki/Chaos_theory
f(x)=x^y doesn’t satisfy those 3 conditions. Nor does the paper you link say that either.
- Comment on [deleted] 2 weeks ago:
No closed form solution is one property. It’s not wrong, only incomplete. But if a system of equations had a closed form solution, it wouldn’t be called chaotic. For example any exponential equation like x^y is extremely sensitive to initial conditions yet it isn’t chaotic.
- Comment on This AI App Is Using an AI-Generated Ad to Show How Easy It Is to Generate AI App Slop 2 weeks ago:
Isn’t that the right thing? If they didn’t use AI, people would be saying “Haha AI app has to use real people.”
It doesn’t mean it isn’t slop though.

- Comment on [deleted] 2 weeks ago:
A double pendulum is bound by definition! It is a fixed point, a line with a 2 axis joint, and another line. That’s the definition.
Just because a system is chaotic doesn’t mean it can move in unlimited ways. A chaotic pendulum cannot move outside it’s predefined limits of its geometry despite being chaotic.
The real world imposes far more constraints. A pendulum starts out in a known state. It gets pushed. It moves chaotically for a minute, then returns to its original rest state.
In the context of Hitler’s parents, you shove the dad, he moves chaotically for a second, then goes back to walking. No long term change has happened.
- Comment on [deleted] 2 weeks ago:
Chaos means that a small change in initial conditions can lead to drastically different places in the long term
Yes, what I was trying to explain is that it could (no closed form) but doesn’t necessarily mean that is must. A chain with 2 segments is a double pendulum, the classic simple chaotic system. If you hold a piece of chain and give it a light tap, it will move chaotically for a few seconds and then come back to rest. The system will not have changed. Even with a hard push, the chain can’t move beyond the limit of the links.
If you gave Hitler’s dad a push, he would stumble for a second (chaotically), then go back to walking (return to initial state). Nothing would change.
- Comment on [deleted] 2 weeks ago:
A tiny change could mean a big change but it doesn’t mean that change is unlimited. For example a double pendulum is a classic chaotic system. There is no solution but that doesn’t mean the pendulum can move greater than the length of its segments. It’s still a bound system.
- Comment on [deleted] 2 weeks ago:
The butterfly effect refers to divergent chaotic systems. Chaos in math isn’t the layman’s chaos. It doesn’t mean wild. It only means there is no closed form mathematical solution. For example stepping on a butterfly can’t affect the weather such that the moon would crash into the Earth.
Bumping into Hitler’s parents wouldn’t necessarily change anything. You have to do something drastic such that he was conceived days to weeks apart such that the sperm was completely different. Even a minor delay wouldn’t affect it because the sperm that fertilizes an egg isn’t random. There are selection hurdles in mobility that the sperm passes such that the most “fit” is likely the one that fertilizes the egg.
- Comment on If you had $1500 to spend 2 weeks ago:
It can generate a huge waste but you don’t have to use it that way. I’m working on making my plates use less color changes by separating more but it’s still nice to be able to select a filament that’s been in a dryer from the slicer instead of having to manually change rolls. I also want to play with using different filaments for supports. It uses minimal extra filament but makes supports work much better.
- Comment on New Cars Don't All Come With Dipsticks Anymore, Here's Why 2 weeks ago:
Knowing the exact oil level is very important for new cars. The piston rings are now made of softer metal to get a few more mpgs. If you overfill oil, you will get blow by, damage the rings, and start burning oil. Toyota now has an involved process of changing oil, running the engine, then topping off the oil while the engine is hot so as to not overfill. But not even my dealer follows that official procedure Toyota put in their manual.
- Comment on When will all the folks complaining about loss of Snap and health insurance realize the GOP wants us to die and has ZERO empathy for fellow Americans? 2 weeks ago:
The only reason Fauci was on TV and setting policy on COVID was because Trump hired him to the Trump task force. Trump could have removed him from the Task force. Instead Trump acted like he had no power over Fauci.
That Fauci had been previously working for the government is irrelevant. Trump hired Fauci to the Trump COVID Task Force. Everything Fauci did was under Trump’s control.

So how do the magnetic build plates work? Some materials need high bed temps. 80C for nylon.
- Comment on Why do so many piece of Hardware come with windows only software requiring admin right for installation 3 weeks ago:
It’s new hardware. It needs to interact with Windows or Linux at a level that gives it hardware access. That requires admin (Windows) or Root (Linux) for software to be installed that has the ability to interact with new hardware that neither Windows nor Linux knows about.
Software talks to the Operating System. The Operating System talks to drivers (small programs that understand the hardware). Drivers talk to hardware. Windows and Linux come bundled with hundreds of drivers. But they don’t come bundled with drivers for everything. That’s why you need to install the driver. If software could access hardware directly as a stand alone program, then anything you click on or run on the internet could also directly access hardware and install viruses, Trojans, spyware, etc.
Software that could run stand alone and directly access hardware is how PC’s running DOS worked.
