Hey guys, so I heard that in order to validate my saas idea, I need to make a waitlist, which is what I did lol.

Is there any other way I should try validating my idea?

Also, any feedback is appreciated, and if you like it, I would really be happy if you could sign up!
A charitable interpretation of what you're saying is that humans produce lots of original data from their experiences of the world, like thinking about their experiences, imagining what they would have done differently, and perhaps even dreaming. I agree with the root comment that something is fundamentally missing, and probably it is the ability to iteratively learn from one's own experiences, test understanding, and recursively improve.

There are definitely teams working on applying reinforcement learning to LLMs. Maybe that will unlock new potential from finite training data.
This is very interesting, I've wanted to play Alyx for a long time but could never justify the cost, assuming it needed a very expensive gaming pc. Maybe now I can afford it

Would be a huge selling point for the steam deck if it could manage it on min specs
There is no consensus yet, there is no repeatable metric

It is perfectly valid to say “hey look over there for further review”
I’m so happy to see Flying Saucer still being used.
ray.io, onprem clister up does't work at all...
Rice's theorem isn't relevant here. The goal is not to create a system that produces no false positives, it's perfectly fine to do a conservative syntactic analysis that allows false positives but disallows false negatives, and it's then possible to produce a formal proof that this analysis is sound. It is this formal proof that I would expect to be included in a specification in lieu of English prose.
For a while I though you could explain Valve best by thinking of them as a gaming technology lab rather than a 'simple' game developer, and most of their hit games have been acquired. The thing that sours me on where they've ended up is outside of steam which has become PC gaming infrastructure their projects have had little influence. The big standout project besides VR has been the deck, which I think is less important as a portable device and more as a baseline for low-spec gaming
It's written for engineers, they already know the math, but they don't know how to design and implement virtual machines, objects, compilers and whatnot that it shows how to do.

What laptop do I get right now to run Linux with decent battery life? My dream would be a Mac-like 14 hour battery life experience running Ubuntu. I don't want to buy a Mac or be tied to their walled garden, it's literally my last resort - but I do need a laptop with better battery life than x86_64's with 3 hour battery life in a good day.

So I have 2 asks for folks here regarding github, or well, git-related:

* You know how there is ActivityPub as the protocol for decentralized social networks (e.g. Mastodon, etc.)? Is there something like that for git? More specifically, is there a decentralized hosting option for git, but which is decentralized? I'd like to host my own but also have the benefits of sharing, collaboration, but you know not centralized.

* Ok, beyond storing code on github, I'll be honest, i use it almost like a "bookmark manager" for cool, fun code repos. I literally use the stars feature of github to "bookmark" cool apps, tools, code repos and such...What are other people using to save such cool code repos? Is it simply your browser's native bookmarks (and maybe i should just use that, abd be done with it)? Please share :-)
I do a lot of biking, and TBH I've had an easier time finding enjoyable bike routes near my house in Austin than I did in Palo Alto. During the summer I go biking at dawn and it's great, and during the winter there are usually 70-degree days regularly enough.

Of course, on that measure, Minneapolis blows both of them out of the water -- at least during the half of the year when biking is enjoyable.
I second that. The TOC is unusable. However, it's probably aligned with the author's intention of it being a course and not a reference book.
I just assume it's people who spend too much time thinking about the stock context.
Using things at that scale to talk? It's not a thing in either case.
Yeah, I think people are incorrectly assuming that everyone had the same experience with the stream. I watched the whole thing and only had a few instances of buffering and quality degradation. Not more than 30 seconds total during the stream.
You seem to be changing your argument there.

It absolutely does matter. If one is cycling the storage system annually, $3/kg for hydrogen becomes a minor part of the cost. The cost of this input is proportional to the number of charge/discharge cycles over the timescale indicated by the discount rate, and for annual storage that's not very many.

It's a common mistake to think that the importance of round trip efficiency for diurnal storage carries over to annual storage.
To be fair, I still think hg is king in this area, and it's why it lose the source control battle - because it was so easy to self host, it doesn't need a central service. Git was really complicated to self host.

From mind–body medicine to AI as interpreter of our body–mind

'Words and drugs have the same mechanism of action' (Fabrizio Benedetti)

The focus of current approaches to biomedicine and bioengineering are largely bottom-up – via implementation of specific functions by control of the lowest-level components (proteins, DNA sequences, etc.). However, biology uses an integrated, multiscale competency architecture in which higher levels of organization make decisions about the types of system-level outcomes we would like to control – large-scale shape and complex physiological states. The ultimate example of this is in the nervous system, where cognitive states (goals, beliefs, hopes, intentions, etc.) must connect to the functionality of the body. Recent and classic work on biofeedback, mind–body medicine (e.g., gene expression changes in the brain following meditative practices or exposure to music), psychoneuroimmunology, and placebo/nocebo effects have clearly shown that physiological and genetic states can be controlled by high-level nodes. It is crucial to note that mind–body control is not some unusual corner case relegated to exceptional circumstances such as hypnotic states. Every time one gets out of bed in the morning to begin a day of tasks, what allows this to happen is a multiscale transduction mechanism that converts executive-level metacognitive intent into depolarization of muscle cell resting potential. Thus, our embodied minds already have the capacity to control complex molecular events and harness them toward adaptive actions without each level knowing the details of the levels below and above it. The work of pioneers such as Fabrizio Benedetti [110–113], who showed that the same mechanisms are activated by drug exposure and by expectation of drug, demonstrate a crucial aspect of our evolved architecture that can be exploited therapeutically. This ability of cognitive states to implement complex downstream changes is not a unique feature of brains – instead, intelligence and distributed control are baked into all somatic cells and tissues, and are potential therapeutic targets. The native bioelectric interface linking complex goals (e.g., grow an organ of the appropriate size and shape) to the molecular implementation machinery opens a transformative possibility that artificial intelligence can serve as a powerful GPS that can guide control of living tissue to navigate transcriptional, physiological, and anatomical landscapes. New advances such as large language models offer the possibility of literally being translators between our minds (and their goals of inducing health) and the primitive intelligence of the body by helping to derive stimuli, training protocols, and experiences as therapeutics that shape the behavior of physiological and anatomical subsystems to increase healthspan.

can you tell me about the battery life? I seriously need a new laptop to run linux and I need decent battery life. Don't want to buy a Mac just to have more than 3 hours of battery life
Housing price issues in the US are fundamentally the result of every major city making it expensive or impossible to actually build enough housing. Changing taxes (in either direction) really wouldn't move the needle at all. What's needed are local zoning changes and significant revamps of permitting and approval processes to remove endless discretionary roadblocks from anyone who doesn't like medium density housing.
I was never bullied and was the popular kid, and honestly, I don’t like the concept that all these ‘nerds’ you see nowadays were bullied back in school and it’s why they became nerds, in fact, I never heard of school bullying outside of the US schools, or generally North Americans ones. Maybe movies contributed to that, or reinforced such a phenomenon?
Honestly, I think there are very little prerequisites. I'm an MD dabbling into stats and found the book very well made as well as understandable.
No, that would mostly defeat the point of social networking.
Can someone explain why? Past 3 years have not seen a huge peak like that.

I agree. If AI gets to the point where it can quickly generate endless amounts of novels, TV shows, movies and whatever, the monetary value of such output quickly approaches zero. I can see people having fun generating their own stories with AI, but not paying for generic stuff done by others. It's not even that different from current situation, where there are way more genuine human content creators than demand. Only few succeed, with AI generated content it's going to be even smaller percentage.

Authenticity will become a selling point itself. People will pay more for TV shows with real actors, just like they pay lots for paintings of famous artists, and very little for printed copies that look just like the original. The interesting question is how something will be certified as "real" so that consumers can verify it.
True. However I find that most junior and even experienced programmers struggle with tactical level coding. I'm really suffering with this right now because the small component I'm tasked with making a small change to is annoyingly stateful and deals with 2 abstractions at once. (It processes files and uses the file system and database to store it's state). I'm shocked how badly it has been thought out. I've spent days trying to avoid doing what has gone before, bits bolted on that make it even more difficult to understand. It really seems that pull request culture has just led to any old crap being approved because no one has the band width to think deeply about the actual code. Bring back in person code reviews !
>We know for a fact that gravity is _not_ Newtonian, that the inverse square law does not hold

[citation needed]

The consensus is that gravity - outside of extreme mass/energy environments - works just as Newton described it to many many decimal places.

Emphasized part added because people in the replies thought that I literally think that General Relativity is somehow wrong. Don't be dense. All I'm saying is that gravity at galactic scales works as Newton described it. General Relativity has extremely tiny effect at those scales.
I find the appeals to composition tough to agree with. For one, most queries begin as ad hoc questions. And can usually be tossed after. If they are needed for speed, it is the index structure that is more vital than the query structure. That and knowing what materialized views have been made with implications on propagation delays.

Curious to hear battle stories from other teams using this.
There is a lot of indirect evidence for dark matter. All the direct tests for dark matter particles we have performed have found nothing so far - but since we have no idea what it might be, there's a lot of possibilities to test.
I'm a non-deterministic black box who teaches complex deterministic machines to do stuff and leverages other deterministic machines as tools to do the job.

I like my job.

My job also involves cooperating with other non-deterministic black boxes (colleagues).

I can totally see how artificial non-deterministic black boxes (artificial colleagues) may be useful to replace/augment the biological ones.

For one, artificial colleagues don't get tired and I don't accidentally hurt their feelings or whatnot.

In any case, I'm not looking forward to replacing my deterministic tools with the fuzzy AI stuff.

Intuitively at least it seems to me that these non-deterministic black boxes could really benefit from using the deterministic tools for pretty much the same reasons we do as well.

Is this the book where he denies the HIV-AIDS link?

> In his book The Real Anthony Fauci: Bill Gates, Big Pharma, and the War on Democracy and Public Health, Kennedy writes that he takes "no position on the relationship between HIV and AIDS,"[292]: 347 but spends over 100 pages quoting HIV denialists such as Peter Duesberg who question the isolation of HIV and the etiology of AIDS.[311] Kennedy refers to the "orthodoxy that HIV alone causes AIDS"[292]: 348 and the "theology that HIV is the sole cause of AIDS,"[292]: 351 and repeats the false HIV/AIDS denialist claim that no one has isolated the HIV particle and "No one has been able to point to a study that demonstrates their hypothesis using accepted scientific proofs.": 348 He also repeats the false claim that the early AIDS drug AZT is "absolutely fatal"[292]: 332 due to its "horrendous toxicity."[292]: 298 Molecular biologist Dan Wilson points out that Kennedy falsely claims that Luc Montagnier, the discoverer of HIV, was a "convert" to Duesberg's fringe hypothesis. Wilson concludes that Kennedy is a "full blown" HIV/AIDS denialist.[311][292] Epidemiologist Tara C. Smith suggests that Kennedy's book "even flirts with outright germ theory denial," quoting a portion where Kennedy contrasts germ theory with terrain theory.[312]

Glad to hear the cochlear implant is working well. It's fortunate that the condition we both carry is remedied through a prosthetic like that. It definitely assuaged some of our fears to have that option. If it comes to it that I can have a third child in the future, I will hope that Regeneron has their GJB-2 gene therapy ready, but if not we may well take our chances with the implant.
Buffering typically just consumes the same live stream until there's enough in the buffer. No difference other than the request rate being potentially higher. At least I can confidently say that for the standard players/video platforms. NetFlix could be doing something different. I'm not sure if they have their own protocols. But I'd be very surprised if the buffering used a completely different mechanism.
And even that isn't really true. Rarely people will have to work with anything but the most basic usually language builtin data structures. Usually people glue together a few libraries and build some CRUD.
I suppose if you want to raise a family AND have a huge dedicated lan party area, then maybe 130 sqm isn't enough.

But I do agree with you. We live in a 4 bedroom detached house approx 120 sqm and this is plenty of space for a family. In fact, it's above average space out of all the families I know...

From the hearing last week my main takeaway was that there is a program that nobody in Congress has oversight of. That alone is alarming but not entirely surprising given the abdication of Congressional authority to Executive agencies. I want to believe that the rumors of advanced craft recovery starting in the 40s are real. But, the reality is that UAPs are likely secret advanced human technology. The one thing that irks me about that conclusion is that historically acquisition/discovery of superior technology has been used for domination by the discoverer. Nobody has done that. None of the reported UAPs have been hostile. That alone seems to go against human nature. So, I'm left with a conclusion that doesn't make sense in human behavior terms.

The hearing just made me feel like "Independence Day" may have had it right. People in government know but don't tell the president for plausible deniability and non-permanence of the position.
And essays for homework assignments that would get a decent grade, art for the headings of blog posts, rewrites of an email to make it sound more professional, summaries of long documents, or just generally to create something that gives the semblance that you did a lot of work while actually having done very little work.

And yes of course hallucinations are a huge problem for most of these use cases, but they aren't stopping people from using them anyway. We have a new misinformation problem and it has no agenda. It's basically just white noise.

So my money is also on this changing the world dramatically, just not in the in uniformly positive way that the hype said it will.
My burns were on the hands, which is not so nice either.

But air exposure was happening most of the time, the way I cooled my burns, so it definitely was the cooling, that did help in my case.

(A wet towel with ice in it)

And I learned to not mess with the wounds at all. I think the last time I had a burn, I opened the the blister to get the fluid pressure out. Bad idea, this time I left it and it healed way faster. It healed so good, that after my first night of pain and cooling, I did not had to do anything with it, except giving it a rest.
> Who is selected for bullying is determined not primarily by the bully, but by the social group as a whole.

I disagree. I think that the person who is bullied is primarily selected by the bully, and the only influence that others have is that the bullied person doesn't have enough (or large enough) others around them in order to defend them. Others may then pile in once the target has been selected, but it's not in any way a collective decision.

You could just as well say that society chooses the people who get mugged, or the people whose houses are burglarized, or the people who are raped or murdered. I'm sure you could come up with some neo-Freudian way to convince somebody that makes sense, but it doesn't make sense. It's generalization to the point of uselessness if not complete absurdity.

I was bullied as a child. I was picked because I was an easy, bookish target without many friends, and definitely without tough friends. The bullying ended when I hurt a bully in a way that everyone found out about, and that state was maintained when I made a group of friends who would have defended me if a bully had approached me. The cause of all of this was obvious, not subtle or mysterious.
I think there are some interesting points in this. But at the same time I think there's a fatal flaw that invalidates the conclusion.

> Twitter is irreplaceable

The main problem is the author overlooked the distinction between Twitter as a concept for "a communication media channel open to everyone" and specifically Twitter itself.

I can generally agree with the idea of wanting some information source other than "centralized media". I think it is a good thing to want. But there's quite a leap from there to thinking Twitter is so unique in this and so irreplaceable. As if there weren't others before, or after, or currently. As if there was something particular to Twitter.
Can you tell me about your Linux on Mac setup?

Here's my situation:

At home, I develop on a very beefy x86_64 desktop machine running Ubuntu.

When travelling overseas for work, I have an x86_64 laptop which provides me decent performance but only lasts 3 hours or so. All my colleagues are rocking Macbooks which last a whole day and I can't even take a piss without thinking about a power outlet.

What is the battery life for a setup where you only use the outside world Mac as a shell for a Linux VM? Can you run X11 applications remotely with `ssh -X`?

I sincerely HATE the whole Mac OS ecosystem but right now, they are the best in terms of battery life for a mobile device, and I need that.

Thank you for any information you can provide!
I think some country has developed some very cool drones with non-traditional propulsion. I'm imagining gyroscopes inside mounted on gimbals, and when pressure is applied to the gyroscopes they cause the spheres to spin and bend through the air like a ping pong ball, but in a controlled fashion. The spheres are supposed to be 3-6m wide, so filled with helium could have enough lift to counterbalance 50 pounds of equipment.
School really is the problem. In its current form, it can not be sustained without radical reform.

If you look at the suicide rate of children under 14 month-to-month, they only stop killing themselves when they're not forced to go to school (Summer and Winter vacation).

> This will get harder I think over time as low hanging fruit domains are picked - the barrier will be people not technology. Especially if the moat for that domain/company is the knowledge you are trying to acquire (NOTE: Some industries that's not their moat and using AI to shed more jobs is a win).

Also consider that there exist quite a lot of subject matter experts who simply are not AI fanboys - not because they are afraid of their job because of AI, but because they consider the whole AI hype to be insanely annoying and infuriating. To get them to work with an AI startup, you will thus have to pay them quite a lot of money.
Yeah, I _do_ think I would have been embarrassed to be buying a pregnancy test a year out of college, because statistically speaking that would be an unexpected pregnancy. I'd say by 26-28 it would be more likely to be a socially acceptable post-college, in wedlock marriage.

I don't see that being anti-child though.
