In the past year I designed two UDP protocols (for connection measurements and a game server) and last week wrote a DNS server. In my own protocols, I always made sure that the sender has to put in more bytes until a >2^64-bit secret was echoed. Only with DNS this does not seem to be possible. At best, you can refuse a query in an equal number of bytes, but useful responses necessitate amplifying.

Every nameserver out there, from duckduckgo to hacker news, will send back larger responses because it must echo the query.

Does anyone know why this is not considered an issue? Are we just waiting for open resolvers to be eliminated and attackers to switch over to this lesser amplification factor before we start fixing it?

The only solution given the current protocol, considering reasonable compatibility, is to use rate limiting per source IP, which means that someone can use source IP spoofing to block benign sources. This problem can be mitigated with DNS cookies, but I don't know if those are universally supported enough to simply reject any clients that don't support DNS cookies yet. It also means state keeping per client (hello IPv6). If clients would just send back a slightly larger packet than the response they expect, and servers didn't have to echo the query, amplification protection would be much easier to implement.
Water is not even remotely an unlimited resource: https://www.businessinsider.com/adam-savage-scientific-fact-...

We should not go about destroying it, or losing it to space (especially if not using the hydrogen to burn or react to create water again) without understanding the global ecological implications, especially since 97% of the greenhouse effect is due to water vapor, not CO2! Just sayin...

I mean, fine, but these poor people will have no family and will be abandoned in their old age. So I don't think fatalistically accepting "no more kids" is the way forward either. Eventually, public health efforts will just sort of ignore them, and they'll be left to die. It will not help to have no family and nobody who cares about you.

I would agree about the underlying cause though:

> no social safety nets, tenuous healthcare/housing/work access, varying degrees of uncertainty of their economic future

Maybe it's useful for the rich to realize, in their language of GDP, that this is a problem.
Right, big-splash, chest-thumping investments are about the only thing that might be a problem. Not ordinary purchases. But that's not so much buying something, in the ordinary sense, as shifting investment strategy.
I don't want to make myself too identifiable, but it's a fairly big place and I lucked into it more than anything. Can't give any specific advice how to find a similar job besides looking for remote listings at non tech places.

So good food is having access to quality world cuisine like Japanese, Ethiopian, Indian, Polish, Italian, Thai …made by people that immigrated from those area recently and cook it the authentic way?

That’s how I understand your comment.

In that aspect, yes, absolutely. The US provide access to variety of « world cuisine »

Other levels of gov have funding issues, but not federal. In fact, big appropriation bills often create these mega-procurements that companies like BAH latch on to.

Government's ability to attract people who could execute a project like this requires different compensation and career incentives. Base pay is capped at <$150k for the highest GS level at the highest step. There's also no real potential for bonuses or equity.

Beyond pay, government careers fundamentally optimize for low-risk decision-making. The goal is to not get fired over 20 years so that you can retire with a pension. This is why contractors like BAH gets hired: you, as a government program manager, don't get fired for going with a brand name even if they fail. If you hire some unknown development firm with great tech skills and they fail, you get canned.

There's also a lack of bold leadership and urgency that is customer-experience focused. Healtchare.gov benefitted from some amazing engineers, but the true catalyst for its comeback was that Obama realized it was a do-or-die initiative for his administration. His team moved heaven-and-earth to steamroll entrenched vendors, recruit talent, and hold people accountable.

Leadership and talent are what make the difference.

Water vapor condenses and falls as rain. It does not linger in the atmo like CO2 does.
You can look up velomobiles. They are quite expensive though.
My intuition is that those are 3 of the select few companies that are not in a bubble. I would add Google and Amazon to that list too.

They make insane amounts of money and continue growing at a steady pace. Apart from Facebook, they have all shown the capability to expand into other verticals and successfully end up as major player on a consistent basis. This sets a high ceiling on growth despite being country sized already.

To me, most other big tech companies are inflated by the promise of ending up like these money printers and not because they have the money to show it. Uber, Doordash, Zillow, Airbnb, Netflix all have valuations that are completely disconnected with an 'average case outcome '. Don't even get me started on literal gambles like Lucid or Rivian which have 100b valuations. Stripe and Elon Musk Inc. might be the only recent ones to show successful ability to scale horizontally.

At the end of the day, the real way to make money is to provide real tangible value over the long term. Making money on the margins for someone else's labor is all well and good, but that runs into hard scaling limits fast. Even Google and Facebook know that the content creators are their value, and the customers are advertisers.

Nvidia, Unity, Cloudflare and similar companies with products with tangible value will survive most downturns. Non-ads based companies that extract value on the margin will struggle in this bear market.
I too expect brutal, decimating euphemisms across the industry in Q2.
Very much aware. Have gone through the USDS hiring pipeline and was extended an offer. Your tour of duty is limited (between 6 months-2 years) due to how they hack the GS payscale, and I argue USDS/18F has the leadership and talent to deliver based on all available evidence. Matt Cutts did exceedingly well considering resourcing and his mandate, and I have similar hopes for the new USDS administrator. They produce results, full stop.

The selling point might be to finally have an "automatic" bike. Standard derailleurs are basically like having a stick shift on a car. The rider has to be trained on how to use them and they will make errors like leaving the gear setting too high when going on an uphill and then being unable to downshift because they aren't turning the pedals fast enough due to the high gear ratio.

This is literally just get on and start pedaling and the bike figures out the rest. It even makes e-bike controls super easy, since you can just set a speed and start pedaling and it will supply just enough juice to make up the difference.

The obvious downside is that it's going to be less efficient than a chain drive, because nothing beats a chain drive. But if you basically get the benefits of an e-bike for free then the efficiency loss isn't a big deal for the rider.
writer here. I do mention housing costs specifically as being a probable large factor, as well attempts at financial pro-natalist policies in Europe. I recognize the data you share above, but it's not clear to me that that any solution can come from economic policies alone. After all, the places that have the most children today are very poor with far more uncertain futures.

That said, I'm certainly not an expert and this is a very complex issue. My main goal in writing this was to spark a conversation and get people thinking about this. Would love to hear your further thoughts.

Like others, it didn't at first make sense to me when thinking about efficiency losses and material complexity, but later realized it might have a place in certain battery-electric delivery bike applications where the majority of the power will be coming from a pre-charged battery. Think about how one could, in a worst off case, charge the bike pedaling in standsill position in a shaded area (while reading a book or using your phone) before trying to continue using the bike.
Simple: It is not the responsibility of the Fed to evaluate and empower or degrade certain markets according to what "smart investments" should be. This is ultimately up to the banks that receive the money and the people who come up with investment ideas.

I have no issue with online reservations or contractors,
but do have an issue with the incentive of application fees:
to enter a lottery for a reservation, every applicant pays
a fee, whether they get a reservation or not. After the lottery,
the contractor keeps all the application fees.[0]

The contractor could increase their profit at very little cost
simply by getting more people to
apply for the same limited number of reservations.

"in reality you'll be wet two days out of three."

I walked and cycled to work in Edinburgh for ~20 years and I really didn't get wet that often, although I did certainly get drookit a few times.

Edit: I spend quite a lot of time in the areas of Scotland that are pretty wet (> 3000mm/year) - Edinburgh isn't anything like those.
This was a really interesting thread. I see what you guys are talking about all around me, the mis-used liquidity or whatever you want to call it.

Is there any growing startup that's not bleeding money? Isn't what the seed and Series A and maybe B funding is about? After series A funding I'd expect some revenue stream, but not enough to pay expenses, after B series, they should have a plan to profitability and some proven customers that show that they can actually get that revenue, and after C I'd expect them to be executing to that plan.

If bleeding money scares you, then a startup is probably not the right fit, a huge number of startups fail.

No. You should still be able to buy fresh strawberries from your local farmer at any time they are in season. Which might be almost never, same as it used to be. And sometimes more expensive, also same as it used to be. But you haven't lost that due to cheap strawberries coming in from another place in addition to the locally produced ones. People eating fresh avocado in Chicago haven't lost anything at all.
> non-productive Speculative investments tend to get punished at the end of the cycle by losing all value, thus punishing those invested in it and restoring order.

To be precise, the investors who are left holding at the end of the cycle get punished. The early investors who got out make out like robbers.

I prefer all wired connections. Many things are wireless but I use wired as much as possible. I have a wired internet connection, keyboard, mouse, display, telephone, etc. We can clearly know what it is connected to without needing configuration, there is less wireless interference, spying, etc.

The radio is wireless, but that is public broadcast and is not a connection to a specific device. Sometimes it is unreliable, but that is not much of a problem in this case.

Sounds like it. There seems to be two paths due to the due diligence not being done by Musk.

1. Accept the 1bn backout and accept that Musk will look like a fool.

2. Sell enough Tesla stock to finance the deal, while risking a total meltdown of the Tesla stock price.

The lawyers are most likely trying to devise a third option, but it's very hard to see how that can play out.
My guess was always that a post on a particular topic might make someone interested to learn more about that topic. If that person then finds a related link interesting, they are more likely to share it if the original post did well enough to indicate that other members of the community are interested in the topic. In some ways it feels a bit like the meme culture of other communities, where users are more likely to post items that are related to previous successful posts.

The main interesting thing to me is when the “topic de jour” has very little to do with what I’d normally associate with HN (language genealogy, Neanderthals, and ancient currencies are some examples from recent memory).

I agree some play the game of working for the KPI's as defined.

The main point of the proposal was always clear up front. I was not the one deciding on KPI's it was a joint choice.

For the SAME business applications and SAME business processes:

- At the end of a quarter you either spend less OR more with your infra costs including required teams.

- At the end of a quarter you either have more uptime OR less uptime.

- At the end of a quarter you either spend more on licenses OR less.

Some KPI's are somewhat objective.
The controller on my e-bike indicates ~120 watts of regen from the rear-wheel. I'm pretty sure that's limited to increase life of the battery; there's plenty more available under heavy breaking.
I wouldn’t know this joy. Literally no one I know who hasn’t lived in SF is ever interested in coming to visit. Even people I know who have family here have instead convinced their family to move away so that they don’t have to visit SF anymore. I’ve been here seven years.

Maybe your experience and people who live in LA or SD differs but seems fuckall want to visit SF. None of my friends outside of SF work in tech either. They’re all normies. (Professors, teachers, engineers, sales, etc.) I don’t think people visit SF for fun very much.

It bears repeating that there is no "what the house is worth" in the abstract.

No, but there is a 'what was selling price for similar homes in this area' price in nearly every specific.

Listing prices are intentially set to be much lower than selling prices. Selling prices are the real prices, listing prices are fiction.

People paying 20% over listing usually means that listing was 20% under selling. Boring! And not financially imprudent!

People paying 20% over average selling in the area, for an equivalent home is what raises my eyebrows as financially imprudent.

Yes. And J has & to bind left or right argument to a dyad making it a monad - e.g. -&5 allows (-&5) 11 which evaluates to 6, while (5&-) 11 evaluates to _6 .
I wouldn't even call it an `understanding` more just a `reality`. Markets can stay irrational longer than you can stay solvent and the last 10 years have been an amazing case in point, but they can't stay irrational literally forever.

There's a gravity to it. At some point whatever is inflating the values artificially is going to hit some kind of force against it and people are going to want the underlying cash flow. It would be the equivalent of a sort of financial perpetual motion machine if this never happened. I'd argue that's not an probability but something more like a law of physics and is actually literally constrained by the laws of physics (it requires continual population growth, consumption growth, and growth of energy use to keep some of these valuations rising)

Tesla made more money last quarter than Ford, GM and Toyota. Toyota made 10x the number of cars as Tesla. Tesla is growing vehicle production 50% YoY, while growing profit even faster (having barely hit economies of scale yet). Tesla has a backlog of orders approaching a year in many regions. Everyone else is losing money on their EVs and can't make them in volume production, can't find the batteries for them, because they started 10 years too late. That's the reason for Tesla's valuation, it's pretty simple.

Whether you believe the competition will catch up, or Tesla will fail for some other reason is besides the point. I'm just trying to show that the current valuation is not "insane" given current trends, there's a very real logic to it and not (completely) FOMO.

Correction: Toyota's earnings were higher than Tesla, it was operating income that was higher (remembered it wrong).

I don't think this is true. GS grades are capped by the compensation of Level IV of the Executive Schedule (sometimes with locality pay they would exceed that and so they get capped), which is roughly the same as Congress salary, but definitely SES pay tops out a good 25k above that.
