You’d need to actually support your assertion that higher FPS is objectively better, especially higher FPS via motion interpolation which inherently degrades the image by inserting blurry duplicated frames.

People are “used to” high FPS content: Live TV, scripted TV shot on video (not limited to only soap operas), video games, most YouTube content, etc are all at 30-60FPS. It’d be worth asking yourself why so many people continue to prefer the aesthetic of a lower framerates when the “objectively better” higher FPS has been available and moderately prevalent for quite some time.


PID loops work best when you have active control for both heating and cooling. PIDs are also best when you have a single optimal point you’re aiming at, there’s a kind of fundamental mismatch here in that there isn’t really a “too cold” for your system, you’re just aiming to keep the system below an upper limit while hopefully keeping fan noise to a minimum (otherwise you’d just send it and run at max 24/7).


A simple PID wants to keep it at a setpoint, but it’s easy enough to layer a target change on top of it, some hysteresis so it’s not pulsing on and off, perhaps with control authority depending on the the target, etc. but then that gets complicated and usually manufacturers aren’t going to expose those sorts of tunings to the user.

For most people a fan curve is more obvious to work with and it’s largely good enough without the irritating behaviors insufficiently tuned control loops can exhibit.


Not if total duration was limited to some small number of re-ups (or the fee ramped up at some greater than linear rate)


Or you could just buy a MacBook Air for like $900 (or one of the windows snapdragon machines, but it you care about avoiding Intel I’m assuming you want Linux and doubt the support is as good as asahi on Macs)


I guess that's the issue? I spent nearly $2800 on my current laptop, top of the line specs at the time. I'm just not the kind of person trying to compare down to A $1000 mid-level Mac. I need to use this thing professionally.

In that lens, the config I played with (before ram prices surged) ended up around $2200 and it felt nice knowing I could upgrade the GPU down the line for $400 instead of pondering if I can last another year or 2 before things fall behind. As long as the chassis and screen is solid I can deal with some compromise for that value.


Sub a $2500 MacBook Pro in for air then for your needs. In several years if that new GPU is actually worth an upgrade it will almost certainly need more cooling or have higher power demands than current framework logic boards/chassis can handle.

Even on desktops where constraints are easier, piecemeal hardware upgrades of anything but storage and ram has never been worth it or done much to extend system lifespan.


Macbook air = small keyboard, small screen, limited battery, all parts expensive to service, etc. Try hacking a Mac Mini instead: https://github.com/vk2diy/hackbook-m4-mini


A MacBook Air is just a Mac mini with a keyboard, screen, and battery. You can choose to attach the same peripherals to your MacBook, and have the flexibility of a laptop when you need it. Paying a couple hundred dollar premium for this is a good deal.


The MacBook Air has a standard size keyboard.


battery is good even on m1 air and better on 15' airs which have bigger keyboard/battery


Snapdragon support is decent to great these days, and importantly it's all in the mainline kernel tree.

Edit: though it should be said that what I think is good might be a far cry from you think is good. I did use a Thinkpad X13s as my primary work machine for 6 months, though.


Unfortunately it's pretty device dependent. My SP11 seems pretty tough to get working :(


Literally just picked up a 13" M4 Air for $750 from Best Buy for my wife. It was spend $500 to replace her older MBA screen or a bit extra for a whole new device.


I mean, this could literally be the last laptop shell, screen, keyboard and power adapter you ever buy. That's a fantastic sustainability story. Not to mention that if it dies you are never at risk of having to replace the whole thing unless it melts in a fire.


It could be… but it won’t be. Internals will be outmoded quickly, and I would be shocked if logic boards from ~5 years from now will still be compatible just as needs evolve (especially around cooling and power delivery)… and this is all before physical wear and tear on screen/keyboard/ports.

I would be very surprised if many frameworks are upgraded ship of Theseus style for decades, or if the total cost of ownership (and even ecological impact, most of the nastiness is going to be the electronic internals, not the metal casing) is lower than for someone buying a more integrated laptop ever 5-6 years.


>It could be… but it won’t be.

Hard to say. If people boast about a ThinkPad lasting a decade, I see no reason (post Moores law) that this can't last that long. The only think not obvious on how to replace is the screen and speakers.


But my nearly 10 year old ThinkPad hasn't needed upgrades to last that long, it just has decent build quality. Will the Frameworks last that long?

A good test would be to work out what's the oldest in-use Framework (which should be one of the first, if not there's an build quality issue) and see how many upgrades were needed to keep it functioning compared with similar era machines from other manufacturers.


In the context of the massive amount of throwaway packaging involved in the food supply chain, or every other part of the supply chain for every consumable we use, how big a deal is that? Are electronics uniquely impactful in terms of sustainability versus eg plastic clamshells to transport apples?


Civilian GPS (as in, the DoD’s Navstar) alone isn’t accurate enough to actually place you on a specific road. To compensate, auto navigation systems will snap you to the nearest road parallel to your current heading. Tesla likely didn’t consider the edge case of ferries and other off road situations in their mapping software and you hit some corner case bug.


This used to be true, but the DoD turned off "selective availability" (the intentional degrading of the civilian signal) back in 2000, and the current generation of satellites do not have the capability (https://www.gps.gov/selective-availability). What they do have though is a separate, encrypted, military broadcast that can be used for those purposes (I think the plan in those situations is to turn off civilian GPS entirely - but I think that there's no reason for that, now, due to the other navigation systems like GLONASS).


Even without selective availability gps is only accurate to within about 30’ in normal urban conditions which is more than enough to punt you over to a side street without heuristics on top.


Your device will use a lot more than the Navstar constellation to get a position these days.


These are all riffs on "Powers of 10", a film made in the 70's for IBM by Charles and Ray Eames: https://www.youtube.com/watch?v=0fKBhvDjuy0


Being a bubble does not mean there is no value in the thing, only that investment is outpacing the intrinsic value of the thing which is inherently unsustainable and will cause a collapse at some point. This also does not imply that the collapse will lead to a future value of 0.


I mean, at this point we are arguing semantics and speculating on future events. My opinion is that there's no bubble. Yours is that there is a bubble. That's fine, we will see probably sooner rather than later (I expect the bubble / no bubble scenario to materialise within the next 10 years, probably even the next 3).


In what circumstance could the banking system collapse but leave the electric grid and all other infrastructure which supports the internet intact?


The internet is more resilient than that. I wouldn't want to live in a country where the banking system has collapsed, and one of the reasons is because I expect that this correlates with unreliability of the power grid; but you can run a lot of useful pieces of software on a computer powered by solar panels and batteries in the wilderness with a satellite uplink, including a bitcoin node.


Ah yes. And everyone in a country that suffers a banking collapse lives in a wilderness with solar power and a sattelite uplink.


Yes. And if a country with say 200m people suffered a banking collapse, everyone could do a Bitcoin transaction every 40 days (assuming everyone else stopped using it), and would use only about 1% of the world's electricity. Great stuff.

Venezuela?


Do Venezuelans _actually_ have much documented usage of crypto, or are they simply using foreign fiat like the USD and Euro?


Why would that be the case? Copyright (at least in the US) only restricts distribution, performance and derivation.


no, it restricts copying, making copies


“Copying” here refers to distribution and derivation, at least in the US. It is entirely legal to create copies of media for personal usage for instance (so long as you aren’t circumventing DRM, thanks DMCA).


from the about page:

Standard Ebooks is organized as a “low-profit L.L.C.,” or “L3C,” a kind of legal entity that blends the charitable focus of a traditional not-for-profit with the ease of organization and maintenance of a regular L.L.C.

corporations cannot make "personal copies" of copyrighted works, otherwise they'd buy just one copy of microsoft office


> corporations cannot make "personal copies" of copyrighted works, otherwise they'd buy just one copy of microsoft office

That would surely be a license violation, not a copyright violation?

They absolutely can (and do) make copies of the Microsoft office binary and shuttle it around their network/backups/etc, activating licenses only when they need to assign a copy to a particular user


This isn't correct. It is infringement, for example, to write Harry Potter fan fiction in private on a typewriter, even if another soul never sees it. Copyright includes creation, not just distribution


What you describe would almost certainly be considered fair use until point of distribution - it’s non commercial, transformative and has no meaningful impact on the market value of Harry Potter.

Copies for private use are going to be similar, and while I’m not a lawyer it feels like it’d be a hard case to make that work being conducted in private is going to have a meaningful impact on the market for Nancy Drew novels in the next 30 days.


Market harm is not required for something to count as infringement, but it matters for certain defenses and damages.

Simply writing new adventures for existing copyrighted characters is usually treated as creating an unauthorized derivative work. Writing Harry Potter from the perspective of the Weasley twins, for example, is not fair use.

Distribution is one part of fair use but it isn't the focus of it - fair use is a defense against infringement, but it's still infringement.

You're really missing the crux of fair use:

"Noncommercial, educational, critical, or transformative uses (like commentary, criticism, news reporting, parody, or research)"

How closely does writing Harry Potter fanfiction align with commentary, criticism, news reporting, parody, or research?

Fair use is more about: writing a critique about Harry Potter. Or a Weird Al style song about it. Or presenting parts of it in a paper you're writing for class.

This is all easily searchable stuff. Copyright is extremely draconian when you really look into it.


https://en.wikipedia.org/wiki/Fair_use#4._Effect_upon_work's...

Seems to say that market harm is the single most important factor in fair use, and it's basically impossible to show that a person writing their own fan fiction without any distribution would prevent an author from exploiting their own work.


If you think about it, writing “Harry Potter” on the internet could be infringement because those words might be in the book, and most worrisomely you are inducing people to make “copies” of the books in their minds. There’s no way to calculate what you owe Rowling from this post, it could be infinite.

(Thankfully I’ve never read those books so I can say the name without infringing)


Better let AO3 in on that


Not sure why this is downvoted. It's factually correct and is said in what I believe to be a fairly neutral way?


Because people insist on discussing copyright as if there is any part of it that makes sense, and as if it operates how they think it should.

They derive a history of it from all of these principles that they made up, then propose a future which is always a moderate compromise between the guiding principles that they made up and the history that they made up from the guiding principles that they made up.

Things are as they are because powerful people made them that way, and built on that. The length of copyright is justified by the fact that it got past Congress and judges. What you're allowed to do is vague know it when I see it stuff, and has always been a patch on top of what you're not allowed to do which is always very clear: anything you don't have a written grant of permission to do.

People talk about "fair use" like it is a real abstract principle, rather than being some weird legal wording by a judge from a few court cases where something felt just too minor and silly to be a violation but was obviously, by the letter of the law, a violation.

I'm fairly sure that under the letter of the law you're allowed to read a book you own or listen to a record you own more than once, but I wouldn't bet on it. For all I know it could be an exception called "private repeat performance of licensed material" which is not a law but actually guidance written by the counsel for the Librarian of Congress based on two court cases from the 1930s.

edit: when I was a kid, you wouldn't put the song "Happy Birthday To You" in a movie, and you would edit it out of a documentary. This was never determined not to be a violation, it just got so embarrassing that it was somehow determined that the copyright had lapsed. Archive.org was in a years-long kerfuffle about 78s. It's not about sense, it's about power.


Fair use and the 4 criteria for determining if it applies to usage is literally written into the letter of the law, passed by congress in 1976: https://www.law.cornell.edu/uscode/text/17/107

Its squishy and specific application relies on interpretation guided by precedent, but that's true of just about everything in legal systems guided by common law.


Is it factually correct? Has anyone been able to prove infringement or apply a fine for writing fanfiction in your own journal or something?


I think you’re burying the lede there: this hypothetical war would be fought in Asia because China is completely incapable of projecting force to the North American continent. Without that ability to credibly threaten America China could not possibly win a war against it.

The conflicts which superpowers have withdrawn from have been against occupied nations which were in no position to ever become a future threat, this would not be true in a conflict with China, as China could conceivably develop the ability to project force and would be certainly motivated to do so during or after a real conflict.
