I've gone through several periods of obsession with this problem. One of its addictive qualities is that, even if you're getting no closer to a solution, it's easy to find a bunch of related patterns within patterns within patterns, a beautiful balance of order and chaos, a wonderful endless fractal of emerging patterns to play with and explore.

For instance: arrange all integers with negatives between positives, as such: 1, -1, 2, -2, 3, -3, 4, -4, etc. Now choose any integer, positive or negative, and follow it to the next integer. For example, if you choose 3, go forward 3 spaces on the list, landing on -4. This is negative, so we go back 4 spaces, landing on -2, which leads to -1. Conjecture: All integers eventually lead back to the 1, -1 loop at the beginning. This can be shown to be a variation of the Collatz; that is, if Collatz is true, this must be true and vice versa.

I also attempted to prove Collatz by focusing on the odds only, that's where the real action is... Failed of course as it's not quite rigorous enough to disprove potential looping (it does at least prove that it cannot diverge to infinity), but may be of interest to someone else obsessed with the problem: https://youtu.be/P0F4zbNdbTU
Coffee Inflation Is Coming to Your Cup After Blow to Top Crop
Who do I call (and how do I call them) if the person agrees with the automated false positive and disables my account/phone and reports me to the police? Just being accused of having CSAM is ruinous. What's my recourse if there's an innocent bug in their system that reports me to the police?

I was at Apple for more than a decade and a half. I saw an untold number of Michael Bolton bugs [0]. It's one thing when a bug causes a dropped frame in a video or a menu takes a tenth of a second too long to appear. It's another when it ruins your life and bankrupts you defending yourself.

I think you misunderstood the answer with the problem. Coming with the answer to this problem is clearly difficult. But what makes 3x+1 as a problem so hard to come up with?
There are some longer-term deep tech investors out there, or the strategic investors like corporate venture cap...
3x+1 produces binary, up or down, so perhaps the integers are shortcuts or an index to any binary sequence. The termination of the sequence is 4,2,1
That's mentioned in TFA, Apple relented to the FBI's request that iCloud backups would not encrypted. I can't see that changing since scanning for CP won't help the FBI in the vast majority of their investigations (terrorism, drug trafficking, fraud).
What kind of issues did you encounter converting to yarn 2/3?
I didn't get beyond his argument that ML is compression while NLU is decompression but that doesn't seem to be right. ML is often used to decompress data such as increasing image resolution. Of course it needs more data than just the compressed form, but only for training. For inference, of course you can use ML to add assumed common knowledge information.
Very bad article. Watch the 2 videos instead.
I remember trying to use a C compiler on my Amiga but IIRC it was such a pain to use with only one floppy drive and no hard drive (and 512KB RAM). My mom wouldn't buy me a second floppy drive (let alone a hard drive) because she thought this computer thing was just a toy, so I switched using assembly.

Programming the Amiga with a good macro assembler was actually a surprisingly good experience. The official documentation of the various system libraries was clearly explained in terms of the underlying ABI, almost as if it was expected for people to reach out to assembly to write applications.
Frankly, this seems like a weird argument.

By analogy, should not all British politicians also only eat food provided by government food stamps?
Let's both stop spamming this board. I will leave you with this.

Assume we have a huge sample data.

And assume "Equal amounts of over 35 and under 35 applicants, and consistently YoY you're taking 90% under 35"

Would you bet everything that you have on YC being discriminatory (I assume you would because you said "With a reasonably sized sample, no, it really couldn't.")?

Could it be, maybe, just maybe, that people under 35 are more likely to produce more value on average and that's why investors choose them?

Have a good day.
Anything but reuse feels half-assed to me. I want to turn an operational cost of single use dishware into a capital cost of reusable dishware.

Manufacturing snigle use crap because we are too lazy to improve logistics is just embarrassing on some level.
That's it, kind of.

I would say "Done thinking YC is the right fit for me" could be more accurate.

Of course, now they've flagged the thread, so not sure if any of this discussion matters. Instead of cancelling the discussion, it should be actively promoted.

I am not accusing of YC doing anything explicitly. I think they make the right decisions when it comes to what you need in a young team in order to succeed. An example of this is the multiple founder bias. Right on point. Young people are just not equipped for the brutality entrepreneurship can deliver.

I also think that some of their process results in unintentional age bias. Asking for age is one example. Older founders might not need or want co-founders. And relocation is something might be impossible as well. As an example, in my case, I have full industrial-class manufacturing capabilities where I live. Moving to YC for three months, quite literally, means I would be far less efficient and likely get very little done. Or, I would have to abandon work on hardware and focus solely on software.
> There really shouldn't be two standard package managers for JS.

Amen to this. This type of stuff leads to so much confusion especially for beginners. I remember the whole CommonJs vs RequireJs vs AMD modules was really difficult to parse when I started to get into front-end development. Yes having multiple choices lets us experiment with alternatives, but I think we underestimate the costs of complicating the ecosystem as a result.
It only seems far fetched if you have a preconceived idea of Native peoples being uneducated simpletons, which unfortunately is the prevailing myth. They did indeed have environmental knowledge and planning abilities that allowed them to prosper in a completely different model of land management than what we think of today.

The Wiki article about Native fire management cites a variety of reputable sources. It's a good read: https://en.wikipedia.org/wiki/Native_American_use_of_fire_in...
Probably something like that. Maybe something like learned helplessness too, as I've heard countless times that it's too late, that an individual can't do anything.
Ha. Thanks, AnimalMuppet.
Well, hell. Apparently I got in on a sale. I just purchased it directly from Izotope's store. It's not showing the discounted price for me now.

Sorry about that.

the students living expenses should also be paid for accordingly, I forgot to make clear.
Reading the Wikipedia page for the Collatz conjecture is interesting; the time-space tradeoff item specifically made me consider the benefit of using a couple of terabytes of disk space for it. (I think 2 to the 40th of space, for a factor of 40 speedup.) https://en.wikipedia.org/wiki/Collatz_conjecture#Optimizatio...
The article mentioned that they began to suspect the plant was carnivorous when they noticed it was missing a specific gene. I'd be curious to know what that gene is, and why it's linked to carnivorous plants.
Are you suggesting that people who want to opt out of this should stop taking photos on their iPhones?
They do mention activity to inhibit Cytokines, which is an important inflammation cause in Covid. The paper said nothing about inflammation from CBD itself. Since CBD is a medicine for the treatment of epilepsy many people take it already. The paper mentioned only mild side effects.
I, um, may have made such comments in the past. Not recently, though... furtively checks comment history

It's really easy, when you're trying to build yourself up, to put others down. And in a smack-off between advocates for different languages, I never thought about hurting people around the edges.
Love your username, by the way.
The question I ask is simple: If you always do the opposite of what your enemy says you should do, are you more free or less free than someone who decides on their own merits what they wanna do or not?

That is a valid question in this day and age, with a death toll attached.
Unless you have a public reference, I really doubt this is the case.

Because they’d also need to be announcing that you can no longer reset your iCloud password and recover to a new device. And I’ve not seen anything that suggests this.

So I suspect it is encrypted at rest, with a key known to Apple as before as well as this CSAM approach.
I was referring to wars prior to WWI—those where the loss of manpower was directly relevant to the harvest.

And sure, wars could target civilians, and sometimes did. But what you can be guaranteed of in a war is that soldiers will die.
Out of curiosity, would it be feasible to produce enough helium for commercial use through fusion (either power generating or not)?
Interesting that they started with data. Some of the most interesting discoveries I've made have started with me saying "that's weird" while looking at data. From the article:

"Graham's team was doing an unrelated project on plant genetics and noticed that the western false asphodel had a genetic deletion that's sometimes seen in carnivorous plants. The researchers started to think about the fact that this flower grew in the kind of environment that's home to various other insect-eating plants.

"And then they have these sticky stems," Graham says. "So, you know, it was kind of like, hmm, I wonder if this could be a sign that this might be carnivorous."
I guess even if they're not common, clearly the person who first came up with 3x+1 didn't know it was going to be so hard to solve. So it was a random simple problem to formulate that ended up being very difficult to solve.
The focus of this analysis is if creating tooling and researching better frontend practices could result in a meaningful reduction of emissions. Saying "don't use the web at all or the devices that access it" is not very useful in this context.
Did you follow the link to the project list on Github? The actual tool for doing the signing, cosign, is just a binary you can install on your device and generate signatures and keys yourself. The "service" part of it seems to just be having your public certificate vouched for by a trusted code signing CA. I don't see anything in the tooling that requires your users to only trust that CA. If you want to sign your cert with your own CA and tell your users to trust that instead, they seemingly can do that, just as you can do that today in browsers. That you can't do it with Firefox extensions and mobile app stores is a limitation intentionally built into the distribution channel. It's not a limitation of PKI itself. iOS, Android, and Mozilla could have chosen to let users install arbitrary trusted CAs. You shouldn't dismiss all PKI based on the fact that a few vendors have chosen to implement it in a crappy way to make walled gardens.

It doesn't say this on the announcement, but looking at the actual PKI service (https://github.com/sigstore/fulcio), it seems to be entirely possible to self-host the service and roll your own CA.
I found in Wikipedia that Somebody Else™ checked that there are no counterexamples up until 2^68.

So my attempt to find a counterexample is to start at (2^68)+1, and perform the 3x+1 or halving until I get to a number that's lower than the one I'm testing - then I know it's not a counterexample.

Since even numbers start by halving (ie, getting lower), I only test odd numbers.

Please take a look at my profile and reach out if you are interested in a conversation.
England used to be covered in dense forests of oak and other trees. It got almost completely deforested to build ships, among other things, and many of the areas never grew back. And that is what we know from detailed records. Many of the other changes there are no records. We don’t know full details of how extensive the megafauna was in the America’s before humans showed up, and how extensive and intentional was the hunting to extinction of them was. But it definitely happened and at huge scale for a long time.

We have evidence of wide scale changes made by humans long before written records existed. We also now have better records, so it’s easier to point to this one here done by this person, instead of only picking up what is visible in the fossil record (which is by it’s nature spotty and incomplete). But that doesn’t mean it didn’t happen.
I’m not making excuses. The government can mandate that Apple monitor content uploaded to its services. All the other major hosting providers do this already. The only difference here is that Apple is trying to maintain encryption while also giving an out. They can’t give more information to the government if they don’t have it.
Yep here in CO when I go hiking there are layers and layers of downed trees waiting to be lit up like a tinderbox. It WILL start on fire, this isn't going to be stopped. The trees aren't piling up from climate change, it's from years of stopping fires. Unfortunately, now there's going to be a massive fire at some point instead of small recurring fires like there should be.
Fortran is not designed to be a systems programming language and you can tell because it lacks the concept of memory address (hardware has been designed to operate by flipping bits at memory addresses for longer than I can remember). Fortran is a higher level language for describing computations on data.
That's a fantastic link - thanks for sharing!
I'm tentatively in favor of more nuclear power plants, but I'm not convinced it's the only solution. We definitely need more electricity that comes from non-carbon-emitting sources, but solar and wind seem to be winning on cost.

In order to rely more heavily on wind and solar, we will need either enormous batteries or better power distribution across the grid.

Lithium iron phosphate cells should be pretty cheap in mass quantities, and they don't require nickel or cobalt. They can also last a very long time, so cost is amortized over many years. If the batteries cost $100 per kwh and a typical household needs 30 kwh to get through a 24 hour cycle, then that's $3000 worth of batteries per household. The real cost would be higher when you add in battery management systems, chargers, inverters, and so on, but if it's centrally managed it doesn't seem like the manufacturing, installation, and operation cost would be insurmountable.

In terms of the energy grid, I think it would be a good idea to look into constructing major transcontinental high voltage DC lines so the United States can buy solar power from, say, Algeria when the sun is shining there and sell surplus power to Europe and Asia when it's daytime in the U.S..

To sum up: I think nuclear could be a part of the solution, but it isn't the only option. We do have alternatives.

> These problems are more typo/syntax-based rather than logic-based.

Sure, but you can also see why it could take absolutely ages for a novice to work out what's wrong, right? The bitwise operators will work for evaluating logic like this in some cases, but not all. And the student knows it's something like "&" for "AND" and "|" for "OR". Could be a really tricky bug if you've been introduced to logical operations, but not bitwise ones, and don't therefore realise they could exist & be confused.
Going through this, it has the old "A full understanding of an utterance or a question requires understanding the one and only one thought that a speaker is trying to convey. " claim, which continues to not make any sense, because obviously people don't do that; as much as I would like to be understood in precisely the way I mean, down to the most subtle nuance/shade of meaning and connotation, at least much of the time, this is not something we can actually get across in an at all reasonable amount of time.

Also, claiming that natural language is infinite, if taken literally, would imply a large and contrary to the common consensus claim about physics, contradicting the Bekenstein bound and all that.

But one thing which seemed, at least initially, like a point that could have some merit, was the point about compression vs decompression.

But the alleged syllogism about it, is, pretending to be much more formal/rigorous than it is, and is also kind of nonsense? Or, like, it conflates "NLU is about decompression" with, "NLU \equiv not COMP" which I assume is meant to mean, --
well, actually, I'm not sure what it is supposed to mean. Initially I thought it was supposed to mean "NLU is nonequivalent to compression", but if so, it should be written as like, "NLU \not\equiv COMP" (where \not\equiv is the struckthrough version of the \equiv symbol) , but if it is supposed to mean "NLU is equivalent to the inverse or opposite of compression" (which I suppose better fits the text description on the right better), then I don't think "not" is the appropriate way to express that.
And, if by "not" the author really means "the inverse of", then, well, there's nothing wrong with something being equivalent to its own inverse!
Nor, does something being equivalent to the inverse of something else imply that it is "incompatible" with it.

For something talking about communicating ideas and these ideas being understood precisely by the recipient of the message, the author sure did not work to communicate precisely.

The value in formalization comes not in its trappings, but in actually being careful and precise, etc., not merely pretending to be.

The part on intensional equality vs extensional equality was interesting, but the claim that neural networks cannot represent intension is, afaict, not given any justification (other than just "because they are numeric").

Wow I had no idea, thank you.

I was in a relative's ice boat once. I was pretty wonderfully terrifying -- awesome in all senses.

To do that on water would be quite something!
You would suck as a mathematician (probably good at engineering though)
I want to learn these. How do I start learning good modelling techniques? Are the NFs you’re referring to is same as in DB design? If so, how does that translate to general code/system design. Any pointers you can provide for learning material, concepts, or books will be greatly appreciated. Thanks!
> Let us be clear, this technology is limited to detecting CSAM stored in iCloud and we will not accede to any government's request to expand it.

That seems like such a bizarre line to draw. Why would you spend all of this time and effort building such technology to only fight child sexual abuse? There are adult victims of abuse and trafficking. There are murders and rapes that Apple could help fight with this tech. Stolen items or stolen pets could be identified and returned to their rightful owners (for example, scan all phones within 20 miles of a lost dog).....why is Apple refusing to help fight any of these legitimate crimes?
I agree with you for cars, which is why I think the appropriate approach is to:

1. tax flying, or rather shame airlines who do not compensate aggressively until they all do, and monitor compensation schemes because at the moment, too many are non-sensical blackmail-like counter-factual arguments around cutting forests;

2. ban industrial releases of CO2: all has to be captured and stored; storage is cheap now, so industrials will rather do that than lobby (until storage price go up, but at that points, things will have gotten much uglier);

3. ban new ICE cars, or make those excessively expensive to build: second-hand cars price will explode subsidising current car owners, and opening a wider gap for electric cars. Guarantee loans on electric cars to make them unaffordable cheaper, until the resell value takes over. No need to make gas more expensive: electric cars are cheaper to maintain today. You just have to make it more obvious to buyers.
How does that work; is it something technical built into it? Or do you mean just because after that one knows that it's incorporated upstream, so not needed as a separate entity any more? Because that would also go for a "pull request" by, say, e-mail or whatever.
Last time I looked back in ~2016, Snapchat also persisted chat text contents in the Android app's SQLite database even after the messages "expired".
That's the point, it's _not_ the same files. Instead of extracting 75K individual files on disk, the Plug 'n Play concept keeps every package as its zipped tarball on disk. So, N tarballs, one per package, instead of hundreds of files per package.

Conceptually, it's great. The problem comes when all the other tools in the ecosystem are still expecting a `node_modules` folder to exist and to be able to read those individual files directly, including Node itself.

From what I've seen, the compat story has improved over the last couple years, but there's still rough edges. Last time I tried it I ran into problems with things like import aliases, and of course VS Code and TypeScript and other tooling all had to be tweaked to work correctly with Yarn's filesystem overrides.

But, next time I start a new project from scratch, I'll probably give it another shot.
SHARD | PORTLAND, OR | VANCOUVER, WA | PARTIALLY REMOTE

Shard is a scrappy, boutique web development agency based out of Oregon – we build focused, market-ready prototypes for venture-backed startups and Fortune 100 companies (JPMorgan Chase, MetLife, KPMG) alike. Last year was our best year to date and 2021 has been nothing short of fantastic.

======= Senior Software Engineer ($120-160k) =======

We're looking for an opinionated senior engineer who doesn't like being trapped in a single codebase and enjoys being able to context-switch between projects. You'd be a great fit for our team if you enjoy taking ownership of projects new and old, figuring out what it would take to build "good, bad, and ugly", then picking a favorite and making it happen.

Tech preference isn't important for this role, but the majority of our projects use Python/NodeJS/.NET Core on the backend, React on the frontend, and Docker + AWS + Terraform for infrastructure.

======= Mid-level Python Software Engineer ($100-140k) =======

We're on the hunt for a Python specialist, ideally with lots of experience building applications in Django and DRF. This is a fun role ideal for people who enjoy rotating between projects every now and again – we have exposure to a lot of different industries, ranging from health care (and CRISPR!), to finance and HR, to social media and advertising platforms. You'll work directly with leadership to design well-thought out database models, high performance REST APIs, and lots of integrations with third-party services like Stripe and Mux.

======= UX/UI Designer ($65-100k) =======

We're also on the hunt for a take-charge UX/UI designer who can help us on both internal and client-facing projects alike. We're a pretty small team, so an ideal candidate would be comfortable stepping in to scope out product features, make impactful recommendations on strategy and timing, and manage their own workload.
