No ISP can guarantee speeds outside of their network. Once it leaves their network it's considered best effort. Comcast has about 30 million subscribers. If they were to guarantee bandwidth out of their network, and if every subscriber had a laughably slow 10Mbps connection, Comcast would need 300Tbps of connectivity to every single company and network. For this reason, every ISP in the world "throttles" in one way or another.
If you look at just the pci-e lanes and ignore everything else, the NICs are x16 (gen4) and there's two of them. The NVMes are x4 (gen3) and there are 18 of them. Since gen4 is about twice the bandwidth of gen3, it's 32 lanes of gen4 NIC vs about 36 lanes of gen4 equivalent NVMe.

If we're only worried about throughput, and everything works out with queueing, there's no need for gen4 NVMes because the storage has more bandwidth than the network. That doesn't mean gen4 is only hype; if my math is right, you need gen4x16 to have enough bandwidth to run a dual 100G ethernet at line rate, and you could use fewer gen4 storage devices if reducing device count were useful. I think for Netflix, they'd like more storage, so given the storage that fits in their systems, there's no need for gen4 storage; gen4 would probably make sense for their 800Gbps prototype though.

In terms of disk I/O, either in the thread or the slides, drewg123 mentioned only about 10% of requests were served from page cache, leaving 90% served from disk, so that would make worst case look something like 45GB/sec (switching to bytes cause that's how storage throughput is usually measured). From previous discussions and presentations, Netflix doesn't do bulk cache updates during peak times, so they won't have a lot of reads at the same time as a lot of writes.

Yes, this is exactly right. If you owe money on a device, even if you unlock it, you still owe money. Same as if you're under contract with the carrier...you still have to fulfill it, or pay termination, regardless of phone status.
This reminds me of cat foods' recommended portions.

With my previous 2 cats, one pigged out and gained weight but the other cat didn't. Since both were about the same body size (length & height), I decided to measure how much the non-overeater was eating and feed that to both cats every day.

It worked great. What was amazing was how little food they really needed (both were indoor-only). I was feeding them about half of what the bag said to feed them based on their weight.

If the bag says to feed 1 cup per 15 lbs for example, it's a good bet they will gain weight. And the solution according to the bag's guidelines? Feed them 1.25 cups of course, because bigger animals need more food! Sheesh, what a racket...
Very interesting project! My first thought was, now here someone has taken function coloring and made it a central language feature. But I will be really interested to see what comes out of programming with these kinds of constraints.
> If people want to live in their own version of reality I don’t care. But when their version of reality is ruining it for the rest of us, it is a problem

Are you sure that is a true statement? What exact ruination are you referring to? Are you saying that we would not have had a delta wave in the U.S. if more people had vaccinated? Or that lockdowns would have gone differently? Or schools?

Australia still has a covid problem, despite their lockdowns. Israel is still having covid breakouts, despite their high vaccination rates. It's putting a strain on many health care systems.

What do you think will change if we had closer to 100% vaccine compliance?

> and there isn’t a lot of room for discussion with someone who isn’t willing to engage with reality.

Quite the contrary, there's plenty of room for discussion. You obviously don't understand their point of view.
Not everyone thinks the way you do. This ending to your comment struck me as quite dismissive. That's a lot of people you just wrote off.

Where does it leave us if we can't talk about these things, and respect our different values?
I have a basic question: if git forwards its first argument to git-$arg, then how would you produce a list of all possible git commands?

Is there something like ls, but for possible programs on your PATH? Or is there a way to just get a dump of all executables on the current PATH?

Even still, it seems like you’d have to decide which of those programs to show first in the documentation. And to get a short description of each of them, you’d have to invoke them.

I guess the solution is “use manpages,” but it’s kind of unsatisfying — I’d like to build something like git, but using CLI --help.

EDIT: Seems ... strange.

Ahhyeah I see now it only has a few upvotes - there must've been an algorithm glitch because it was the #5 story on the front page when I clicked on it.

The topic is relevant, but the format of long Q&As with a lot of info on the people and the company, which to me as a random HN reader feels irrelevant, plus the click-baity title, made it look out of place on the front page.

Hope this is constructive.
the dead giveaway is any url and mention of bitcoin

I can see how ppl fall for these. look very realistic.
Adapt.

Restructure child care to account for pandemic. Smaller group sizes, no intra-mingling, contact tracing, nordic style outdoor classes, etc.

Ya, it costs more. Whatever. Investing in childcare is LONG overdue.
> This was a recent article about a couple buying a $7k camera and getting an empty box.

There's apparently a whole genre of "ordered iPhone, received iPhone box with Play-Doh inside instead of the iPhone" complaints.

The theory I've seen is that this is a scam by the purchaser against Amazon's return policy, not a scam by vendors on Amazon against customers. That second option doesn't work, because the customer just gets refunded.

The failure modes of the combination of democracy and America-style capitalism are fascinating, as is the reluctance of those with authority to act, to do so.

The American media is both too docile to ask difficult questions (so as to maintain access), while simultaneously riling up viewers' emotions with opinion-shows. Independent media in other western countries do a better job at holding authorities to account - even with something as basic as asking follow-up questions at press-conferences, or pushing back at incorrect characterizations.
I don't think that applies to just the military. If you actively disobey your boss' direction and do something completely opposite, I'm sure you'd be dismissed or punished for that too.

Fwiw, when I was there four years ago the meal prices were in the $13-15 range, so quite a bit more than I was used to. But if that makes for a more equitable society, good.

> And how I can improve my model.

With no offense intended, I think the "dating affiliate" model you've come up with should be totally scrapped.

First, having your friends send your "profile" to women they know as email "bait" is cringe. Imagine you're a woman who receives this email. What would you think? My guess is that a lot of women will find it creepy or desperate, even if you really are a nice guy and great catch. Even consider how your "experiment" is being portrayed in this news article: you're "tired" of online dating, not enjoying it and have been looking for years without luck. All negative.

Second, you're asking women (who you call "candidates") to take time to submit a profile so that a committee of your friends can decide whether they're worthy of your attention. There's a fundamental disconnect here: the supply of dates you consider to be of sufficient quality is apparently low but you're treating the women as if the opposite is true. Not a good look.

Third, you want to meet a woman and get married right? If a woman applies for the job, why not be respectful and make a decision about whether you want to go out on a date or not? Once again, I think any woman who encounters this "experiment" is going to see this as a huge negative. As a general rule, women are more attracted to men who are decisive and take responsibility for their lives. It doesn't mean you have to act like a NAVY Seal but I believe asking your friends to decide who you date is going to be unattractive to the vast majority of women.

Fourth, I think you should consider the possibility that how you're presenting yourself will have a bigger impact on your results than the model you use to distribute your "profile".

You describe yourself as a "fun guy serious about love" but again, put yourself in a woman's shoes. Does the very next sentence ("steady income, with a good credit rating") scream "fun!"? Do your requirements/preferences for a woman ("You’re kind and have a curious mind. Live within 10km of Vancouver. Or have good wifi") make it seem like you really know what you're looking for, or provide enough meaningful detail so that you might connect with someone you share a unique common interest, hobby, etc. with?

The quality of your presentation makes all the difference and again with no offense intended, I don't think you've got your profile down. Great profiles gets interest, lackluster ones don't. In any channel. Having your friends deliver your profile to women through email won't change that.

Finally, introductions from friends to potential dates can be a really good way to meet women. You shouldn't have to pay your friends to introduce you. If you've let your friends know that you're single and hoping to meet someone and they never introduce you to anyone, it's worth figuring out why.
I've received a lot of handwritten-but-printed-letters (ie. it looks like handwriting at first glance, but if you look closely it looks printed because there's zero artifacts typically associated with handwriting), but I've never received junk mail that's actually hand-written (ie. this post, presumably I won't be able to tell).
I think a lot of people are disillusioned in the military. There wasn't a lot of support for the last wars we've been in among young people, and most people are aware of the hardships veterans can face.

There are benefits, but I think many people feel they aren't worth the risk of death or PTSD. I don't blame them, I wouldn't want to get shot at for $20k/year either.
>I’m still not into the prospect of purchasing books on the e-reader – it’s something I’ll probably avoid

Agree with most of what the author (including a preference for physical books) says but this. I must have spent close to USD 2k on various e-books (I use Amazon because of legacy reasons .. availability of e-readers in India around 2013 etc ) and the joy these purchases have given me can't compare with what I might have gotten with Overdrive etc. YMMV but I like to be able to go back and refer a passage I read 5 years ago.
Then you can only get $1M for one box or $1000 for two boxes. The decision becomes even more obvious then.

The accuracy of the predictor does not impact the two-boxer's argument from causal independence, which I think is a serious problem for the two-boxer.

Tangent Vectors and Particle Swarms
BBS’s are the internet.

Anyway, what I was trying to say was, pre-internet it kinda required post-puberty hormones to be motivated enough to clear the hurdles to accessing porn.

Also, to another commenter’s point, the porn I was able to access was amazingly innocent by comparison to what is probably commonly available now.
It’s not really different than other companies outside of astronauts and some people working in, say, educational outreach. For the vast number of employees, there’s no sort of restrictions or even discussions about what’s said outside of the legal concerns (e.g., using NASA titles to convey a position of agency, Hatch act, etc.)

The real mistake here is was made by a potential intern who was not yet hired. It’s like making a mistake on probation, you likely have very little recourse. It’s completely different for regular civilian employees
Is there a law or rule that (indirectly?) requires the letter grading system?

I considered going to a college that used a non-linear grading system: you’d receive an in depth essay explaining your strengths and weaknesses.

They would still create a standard lettered grade, but they would not give it to you unless you asked, and they advised you not to ask.

It was implied they needed to create the lettered grade to comply with some regulation - possible to show there was no racial bias? Not sure.
> It's so strange the way that American liberals hand-wave low vax rates in minority communities.

As you've commented (but then hand waved), the motive behind the distrust. "An orange man told me" vs. "The US government has spent hundreds of years oppressing our people, and the US medical system fails minorities consistently time and time again".
This post has big problems.

All of the author's reasoning implies keeping backups in tape robot. I am going to bet that most small and medium businesses do not own tape robots, instead they own a few drives for which they change the tapes manually. And most of the standard backup rotation schedules (like GFS, Tower of Hanoi or even FIFO) keep most of the tapes offline, far out of reach of any sort of remote access.

And the whole "cost" section is just absolutely wrong. Author has confused tape drive ($3500) with tape cartridge ($75), and made completely wrong conclusions about cost. The tapes are actually much cheaper than the hard drives when you have enough of them.

As far as disk system, the author seems has this weird idea about keeping the disk connecting but disabling access by turning off switch ports, powering off, etc... Not only this will likely need to be custom designed (I have not heard of ready-made systems like this), but somehow, according to author, the hackers will figure out how to attack the libraries, but won't be able to figure out how to re-enable the NAS access?

And of course one could make argument against the tape -- use your good old GFS backup strategy, but with removable drives instead of tape. One could discuss the cost/speed/operator time vs amount of data stored. Or maybe discuss special write-only NAS with separate security credentials? Sadly, this post contains none of that, just some mostly wrong arguments.
No difference ICANN or blockchain TLD for making an SSL certificate.

Where can this MITM stick his foot in? The blockchain domain record is encrypted and contains the publicly visible target IP-address. Even if accessed via http, it can be instantaneously checked. And upon visiting that IP address, the site forces https encryption. Nobody can know from mere traffic analysis what exactly you are doing within the site, since it's encrypted by SSL.

IPFS encryption isn't necessary either, since content is addressed by its hash which automatically guarantees its authenticity. It doesn't matter if you use https or http.

It's only imperfect in the transition during DNS resolution. A 3rd party can know what site you go to, but not more than that. Suspecting a public generic blockchain-domain resolving node set up for freedom in defacing would be a bit too much. Usually those are OpenNIC servers or huge DNS providers, unless you specify a custom DNS resolver in your settings.

For a book site it's a pretty decently protected transition, actually maximal available for a non-expiring (unmanned) service which it is. Legit certificates expire or cost money. The system behind libgen.crypto is fully unmanned, i.e. eternal, except the files themselves which need hosting.
There is so much misinformation in these comments about so many topics. It’s weird. Like bots or a hired damage control media agency that are meant to diffuse certain topics anytime they come up.
Mostly because Apple Support Site delete any threads that mention these problems, from GPU failure, Keyboard, Display Cable, etc.
The "research into the impact social media has on people is still relatively nascent and evolving" bit reminded me of Exxon knowing in 1979 that fossil fuels caused climate change and for the next 40 years pushing the narrative that the science wasn't settled.

it's not that much harder to write software than it is to clean a toilet -- and it's WAY harder being a roofer than writing software. There is little to no coupling between skill, difficulty, and pay.

Due to our Colonial history, the hankering for "International Recognition" is very strong in Indians. NASA has been turned into a "Brand Name" and bright (not necessarily qualified) kids want the stamp. Hence lacking accessibility/resources/education they can only invent an imaginary persona for themselves and advertise it with the Internet. To them it is more akin to status posturing/posing within a group. With the rise of Social Media it has gotten much much worse since there is no longer any difference between "Fame" and "Notoriety"; everybody wants to be "Noticed" and become an "Influenzer".

PS: One of my classmates(an average student) from college had a interest in Astrophysics and would often checkout the books of Arthur Eddington/John Wheeler etc. It was evident that he was fascinated by it but simply wasn't suited/qualified to read much less understand it.
It's a feature which actually makes fast decentralized search real-time. If no partial function is involved, it won't work before downloading the entire database. It's a feature and beauty, not something to dislike. It's just given.
I wouldn't go so far as to say that's the main reason. The main reason is that doing it that way has proven to yield good results.

We have work to do on how we manage the negative externalities of the approach, but the approach itself has proven solid.
Is it a major problem?

The scams seem super obvious, and if you subscribe to more content you’re interested in I guess they’d go away. Are they really causing you a problem?
This strategy is also doomed to failure. We’re talking about kids whose brains are in full-time adapt-and-learn mode. They will create other language to talk about these things that will completely fly over the heads of the adults and the software. I remember being in eighth grade where kids would make fun of a teacher to their face without their knowledge.
Zyppy – SEO traffic, up and to the right
Yup. And some foods are unbelievably automated. There are GPS-guided, self-driving combine harvesters that will harvest an entire field of grain with essentially zero input of labor. Higher labor costs might somewhat increase the cost of some of the more labor-intensive crops, but your basic staples will still be cheap. If anything it's the cost of truck drivers that might have the biggest effect.
> Does anyone else find it paralyzing just trying to decide what to invest time in each day/ week/ year when you see stuff like this? Which lottery do you buy tickets in? (metaphorically speaking)

I only think it's paralyzing if you're trying to play the lottery, believing that there's a secret you haven't yet discovered that will allow you to win.

But you don't have to play the lottery, and in fact, you might come to discover that your happiness in life doesn't depend on winning the lottery, in which case all of the startup, influencer, [insert get rich quick scheme], etc. nonsense is just a sad and also funny sideshow on the road of life.

Logically speaking, this doesn't make any sense.
I wonder if one creative (and probably stupid) way to leverage GPUs might be just as an additional RAM buffer to get more RAM bandwidth.

Rather than DMA from storage to system RAM, and then from system RAM to the NIC, you could conceivably DMA to GPU RAM and then to the NIC for a subset of sends. Not all of the sends, cause of PCIe bandwidth limits. OTOH, DDR5 is coming soon and is supposed to bring double the bandwidth and double the fun.
No difference between them and the tribes that can destroy you with guns. And no difference between the ones who can destroy you with guns and the ones that can destroy you with baseball bats. In the end, it's all the same, their tribe employs deadly force against you. One tribe gets fancy lawyers to speak eloquently in defense of the deadly force employed against you, another may just kill you and go home to have a beer. Either way, you're still dead.
People's expectations are already very low. But there dozens of these videos playing at any time . It's not like this is a one-time occurrence or under the radar. It's everywhere when you search for certain keywords or just browse certain topics like crypto or elon musk or any major event. You would think these highly paid engineers and such a hugely profitable company could do more to fix it.
And if you have fighter jets buzzing by, the least of your problems is noise.

> That's because their “landing pages” [...] aren't instances

That is a technically correct answer, but it misses the point: they're asking users to sign up before they even see the product. They're expecting that the premise of the site alone is enough to entice users to join, which is very optimistic. It would be better to immediately direct the user to content, and then provide reasons for why they should get an account. At a high level, that's what YouTube does.
I wonder if restricting video games correlates with a rise in crime. China is most likely different culturally in that regard but I’m curious to see the effects of it.
