I'm a little confused about how the object base is looked up in these systems, and if they're sparse or dense and have any size or total object count limitations, and if that ends up having the same limitations on total count as page tables that required the current multi-level approach.

As surely you could consider page table as effectively implementing a fixed-size "object cache"? It is just a lookup for an offset into physical memory, after all, with the "object ID" just being the masked first part of the address? And if the objects are variable sized, is it possible to end up with physical address fragmentation as objects of different sizes are allocated and freed?

The claim of single-cycle lookups today would require an on-chip fixed-size (and small!) fast sram, as there's a pretty hard limit on the amount of memory you can get to read in a single clock cycle, no matter how fancy or simple the logic behind deciding to lookup. If we call this area the "TLB" haven't we got back to pagetables again?

And for the size of sram holding the TLB/object cache entries - increasing the amount of data stored in them means you have less total too. A current x86_64 CPU supports 2^48 of physical address space, reduced to 36 bits if you know it's 4k aligned - and 2^57 of virtual address space as the tag, again reduced to 45 bits if we know it's 4k aligned. That means to store the tag and physical address you need a total of 81 bits of SRRAM. A 64-bit object ID, plus 64-bit physical address plus 64-bit size is 192bits, over 2x that, so you could pack 2x the number of TLB entries into the same sram block. To match the capabilities of the example above, 57 bits of physical address (cannot be reduced as arbitrary sizes means it's not aligned), plus a similarly reduced to 48 bit object ID and size still adds up to 153, only slightly less than 2x, though I'm sure people could argue that reducing the capabilities here have merit, I don't know how many objects or their maximum possible size in such a system. And that's "worst case" 4k pages for the pagetable system too.

I can't see how this idea could be implemented without extreme limitations - look at the TLB size of modern processors and that's the maximum number of objects you could have while meeting the claims of speed and simplicity. There may be some advantage in making them flexible in terms of size, rather than fixed-size, but then you run into the same fragmentation issues, and need to keep that size somewhere in the extremely-tight TLB memory.

Wow.

Congrats, you landed an even bigger egg on your face.

OP, congrats on your progress. This looks interesting, and has the potential to help a lot of people.

Mr. Throwaway, do you have nothing better to do with your life?
Since this addressing scheme is <object, offset>, and as these pairs need to fit in 64 bits, I am curious, is the numjer of bits for each part is fixed and what are those fixed widths. In other words what is the maximum possible offset within one object and the max number of objects?

Probably segment registers in x86 can be thought as object identifiers, thus allowing the same non-linear approach?(Isn't that the purpose of segments even?)

Update: BTW, another term for what the author calls "linear" is "flat".
Hotels get either a deposit or pre-auth on your credit card and have you sign an agreement that you're on the hook for damages. Yes, they are probably not going to pursue you in excess of the pre-auth, but they're largely covered in typical cases, and you won't win a chargeback if you damaged a room or even the linen.

Also, there are already shared DNR lists hotels use for egregious misbehavior. Within hotel chains, there are more extensive lists.

Other android phones are also other companies, wouldn't exactly call that deep connection, but a connection nonetheless. Re pixel, that's a pretty small business relatively speaking.

> Yeah, no thanks. A good manual transmission is a core part of the driving experience.

I learned to drive in manuals (because they're more common in the UK). I currently own two automatics and drive a variety of manuals, automatics and EVs that are kind of inherently "automatic".

I don't see any difference in "driving experience" between manual and automatic. What do *you* think the difference is?
Pro tip for any BMW owners, MHD is a tuning company that makes great hardware for this.

Even if you're scared of tuning your engine, their dongle originally for that purpose is one of the fastest interfaces and supports Wifi.

The difference in speed is large enough I stopped needing a battery charger to flash my ECU and TCU (would still recommend one though since you are technically playing russian roulette doing that...)

Bonus: If you do care about tuning, they have some excellent off the shelf tunes to go with it
What is the point of growth if you can't make a successful business? Legitimate question here. I always had a hard time understanding, especially in regards to companies that are still not profitable or just barely after 10 to 20 years.

Seems incredibly risky and not strong enough to weather any economic downturn.

Are companies just copying the Facebook mantra from 2005ish? Didn't FB become immediately profitable once they started selling ads? That was pre ipo.

There's an old adage: If you think auth is easy to write, you probably don't know auth.

I obviously don't know how much it compares to your specific case, but as general advice it's often good advice when phrased less antagonistically: don't roll it yourself because the rabbit hole is deeper than you expect.

On that front, you may think you are paranoid enough, but keep in mind that the service products sometimes have a multiplier effect in play: N developers of various levels of paranoia, M people in various ops/InfoSec/auditing roles, X committees/layers designed to minimize corporate security risk.

If auth isn't your job and isn't your core competency, many times it is worth asking if following the rabbit down the hole is worth the time you could save outsourcing to a multiplier effect of a team that focuses 100% on those tasks. As with most "buy versus build" discussions, it's not just about "comfort" but leveraging those multiplier effects. Can you pay someone else for the years of experience and "rabbit hole wandering" and multiple layers of security audits? Auth is a "must have" feature for most products but in and of itself is mostly a security liability and mostly pure overhead: no customer is paying you directly for your auth features, auth is the annoying hurdle to features that they do care about and will pay you for. All that time spent on auth and auth security audits rarely appear to provide good returns on investment for your product and your customers. Time spent on auth is time wasted from user-facing features.

The examples of `git reset` and `git checkout` are being fixed by things like separating them out into `git restore` and `git switch` which helps a lot in my experience. Also, `git status` does a good job of reminding you which commands to run.
A few years ago someone in the UK put an electric net over their vegetable patch, probably to stop cats. Long story short a cat was killed by said electric net. He was prosecuted but only got a fine of £60 or something. I suspect he might have felt that was good value to eliminate the cat shit from his veggies.

> Or... they just disagree with the assumption that it's even possible for such "egalitarian structures" to exist at scale.

Of course it's possible. Market structures (including "smart markets", with elaborate and perhaps quasi-arbitrary rulesets driving desired outcomes) are quite egalitarian, and can easily scale up to thousands or perhaps millions of participants. The relevant question is when and why quasi-hierarchical organizations might become desirable compared to a market or agoric structure made up of arms-length, strictly codified interactions.
> The idea of the dog protecting the family is common amongst all large dog owners, it's not really specific to pitbull owners.

Ok then my argument still holds true, and you're just upset that I called out pitbulls specifically. Your argument for negative correlation also doesn't really make sense - if it did, gun owners would just stop at buying one gun because they already have one. People who take their self-defense seriously don't usually just stop at the bare minimum.

The worst part is that many of the names were inherited from earlier tools, but usually mangled, or repurposed because the old version was “not needed” (revert) because they’d merged multiple high-level features in the same command out of low-level commonalities (checkout and add being poster children for this)

It's because if we start critically examining this, even from perspectives of foreign adversaries, we might also look, similarly, inwards.

My gut tells me that if we could, there would be phones catching on fire all over the place.

Although a phone has tons of power, and can probably function as a low-end desktop, the lack of a sizeable cooling solution, or even just a plain heatsink, would cause it to throttle pretty quickly.

I have to believe this is the reason, or otherwise someone would have done it already (successfully that is) for such an obvious use case.

There is no centralized way to drive that change on the needed scale. Most humans don’t even view what we’re doing in civilization as shared project, let alone agree that this is required to protect it. I think they fundamentally lack the abstract thinking required. They won’t change until they feel the pain themselves. A poor fit for an abstract, not quite “here yet” problem. In the United States we can’t even get them to agree it’s a problem at all. But I think once we are collectively feeling the pain, solutions will be swift and surprising.
Not surprised. A ton of political writers who got slurped up into Substack all compete over the same niche audience who definitely aren't paying $10/month or whatever for 15 different writers doing basically the same "heterodox" takes. That swarm effect works on "free" mediums like the blogosphere back in the day or Twitter, but it doesn't really scale to paywalled newsletters.
If there is so much competition, why does it all end up in WeChat, the fucking AOL of apps?
Don't worry about the haters. The throwaway's response is verging on trolling and isn't worthy of your concern.

I was impressed by your project and will consider paying down the road. I think an app like yours plus human feedback is a killer combo to help people learn to write better. This kind of writing isn't even really about writing - it's about self-editing.

Good stuff!
Your "other option" means certain disaster, sooner.

We already know what to do: build out renewables. Tax and otherwise cut burning fossil fuels. Renewables are already radically cheaper than any energy source ever devised, so the faster they are built out, the cheaper it gets.

Anything else is a dangerous distraction. Any big enough distraction is disastrous.

I think you might be responding to something I didn't write. I was trying to draw attention to the distinction between triage and the projects that go into triage versus work that addresses issues systematically. The GP's comment correctly noted that the idea under discussion doesn't necessarily address the systematic problem at hand, which is true, but that doesn't mean that triage is not valuable. I also specifically said that the proposed bubbles in space idea may or may not be viable; it's irrelevant to the point I was making.
Well the considerations of growth were wrong and that's why people are getting laid off.

> China has been as friendly to the west as it can be while still protecting its own cultural and economic interests.

I'm not implying you're doing it, but whenever I hear people defend China, they always use the word "culture" to defend totalitarianism/communism, as if they're part of Chinese culture.
If you're coming from git, this is what you need to do to understand Mercurial: don't worry about Mercurial's branches, ever. Whenever you want to use the term 'branch' from git, translate it to 'bookmark'. Mercurial's branches correspond more directly to svn's branches--they're immutable properties of a revision--but it's not a terribly useful property, and you can forget about them entirely and be perfectly productive.

Although note that unlike git, you don't need to use Mercurial's bookmarks since Mercurial is perfectly happen to let commits sit around without having names pointing to them.
Growth where more growth leads to greater and greater losses, this sounds like 2000 all over again. You know what they say, those who don't learn from history are doomed to repeat it.

This assumes it only takes a single disk read to locate and retreive an object from the cache (which is unlikely to be the case).

Do you mean in general? There are two reasons given in this thread: medical research and pet (snake) food.

I expect I don't need to explain why it's best to kill the mice humanely for medical research which involve dissection of some sort.

For snake food, it's best to feed mice that have been euthanized. Feeding live mice is cruel to the mice, who experience terror right before death, and there is also the possibility that a struggling mice could injure the snake.
the movie pass strategy. Sell people 2 dollars for 1 dollar and experience fantastic growth. Growth is irrelevant if you're not making money, in fact growth in that case means you burn it faster.

Hopefully with the end of the easy money era this ridiculous business model dies out for good.
> "awesome rss feeds site:github.com"

First few of those it found had a lot of links, sure!, but no commentary around them to explain why they are awesome which is the other half of the discovery problem, no? If I have to click 50 links to find out what they are - and they generally link to the RSS, mind, without a link to the website which means that clicking will only give me a "Do you want to open this in ReadKit?" prompt - I've got better things to do with my time, really.
Technically their sales would be the full subscription fees, no? So price to sales would be considerably lower. Your point stands with price to revenue though. That said, Substack has an insane amount of brand recognition for a company that only generates $9M in annual revenue, so it doesn't tell the whole story.
Small changes in the median have big effects when you're looking far enough out along the tail.

That's at least part of why professional basketball is so black--there is a tiny difference in average height between white and black, small enough that on average you won't notice it at all. At the very end of the tail, though, it has a big effect.
Even attempting it is disastrous, either way.

The only winning move is to shut down every attempt at such distraction. We know what we must do. The only thing remaining is to do that.
"A Texas lawsuit led to the discovery that its Department of State Health Services was using newborn blood spots not only for research, but also as bartering chips with for-profit companies in exchange for lab equipment. And a subsequent Texas Tribune investigation revealed that the Texas health department had sent hundreds of newborn blood samples to the U.S. Armed Forces to build a national DNA database to help identify missing persons and solve cold cases, and also eventually build an international DNA registry for international law enforcement and anti-terrorism efforts."

> I remember a few years ago, it was one of the most desirable cars and places to work

I don't remember that. Elon Musk has been employee-hostile for over a decade, and the build quality issues have been an open secret since the Model 3.

I suppose the employees who expected to get rich off RSUs would like it, but given that Tesla was supposed to pay less than many other companies, it seems like people could just buy shares with the money they make elsewhere.
I don't think Americans would have the same complaints about national security for the EU, nor do Americans have the same level of concern with regards to market fairness in the EU. American relations with China is very different from the EU.

Also, I'm not sure the public at large cares much about the competitiveness concerns that big tech companies have with the EU. It's not really a story in the sphere of public conversation.
The point is that both groups are unable to prevent fraud.
Yes, good for the EU. It's good to approach new problems with new solutions. Americans worship a decrepit ~250 year old document that was never meant to last that long, and will be left behind because of it.
Ah, ok, I'm tracking your perspective now, thanks for continuing the conversation. Yes, I wasn't really speaking to the damage to the catalytic converter. But I think you may have it reversed?

Doing something like Geo-Engineering may be an important and vital stop-gap to mitigate the worst effects of climate chnage. But it is also dramatic and potentially causes other side effects from crop failures to god knows what.

So when things get so bad that humanity says "yeah let's block out the sun for a bit" we really really want to have studied it hard and have as many countries in the world to have signed up to pieces of paper that say "we tried this crazy thing with our best scientists and it seemed ok, so we trust that it's not a deliberate way to F%%k us over"

The UN might have better wording.
I wonder what the future of Substack looks like, I have seen that they have been trying to push into the podcast space recently. I wonder if they continue to broaden the content they support and just slowly morph into a Patreon type site where instead of featuring just newsletters it is built for any type of content that allows paid subscriptions.
Isn't the Amazon the exception that proves the rule
