dx034··on How Canva saves Amazon S3 costs
If you don't mind it running in a data center in Europe, you could rent servers from Hetzner for ca. $400 per month for 220TB. I'm sure they can provide a few PB on the spot. Spread them across their locations and you have geo redundancy too. Next to no egress fee also allows to have a copy with another provider.

dx034··on Reddit is removing moderators that protest by taking their communities private
Can you really make that much money with behavior data? If that was the case, wouldn't we see more sites with few ads?

I believe ads bring in the vast majority of money, behavior data helps ad targeting and can maybe sometimes bring in insignificant amounts as well.

dx034··on Private equity is buying everything from vet offices to tech conglomerates
It's important though if you don't want to stay at the current company forever. With the right title it's much easier to get a well paying job. Otherwise you'll have to convince future employers why you didn't have that title despite your qualifications and work.
dx034··on Why do railway tracks have crushed stones alongside them?
That was filmed in Germany, I would think safety rules are similarly to the US. Maybe it's not as dangerous as it looks at first glance.
dx034··on Notes on training BERT from scratch on an 8GB consumer GPU
I'm interested in the topic but have no understanding in depth. I like upvoting stories like these to revisit them after a day when there are hopefully some interesting comments and/or clarifications.

I really like the high signal to noise ratio in HN comments.

dx034··on Fidelity has cut Reddit valuation by 41% since 2021 investment
I guess with that definition, Europe has a lot of very valuable start ups.
dx034··on Fidelity has cut Reddit valuation by 41% since 2021 investment
No but usually these things can align quite well. Build a user friendly website and usage will go up. It seemed like reddit worked more on getting usage down by restricting a lot of usage to their app. I don't think that's in the interest of shareholders.
dx034··on Launch HN: Onu (YC W23) – Turn scripts into internal tools in minutes
Can you name some examples? I haven't come across that yet.
dx034··on Ask HN: Is it just me or GPT-4's quality has significantly deteriorated lately?
But I don't get why they would degrade quality? Maybe compression to save resources? Otherwise I wouldn't know what they have to gain from it. If anything, they might lose paid subscribers. I loved the results for the $20 I spent, now I'm not so sure anymore.
dx034··on Ask HN: Is it just me or GPT-4's quality has significantly deteriorated lately?
Maybe it had to do with jailbreaks? A lot of the jailbreaks were related to coding, so maybe they put more restrictions in there. Only speculating, but I cannot imagine why it got worse otherwise.
dx034··on Since when did SSDs need water cooling?
It should be clear that this was only shot for marketing purposes. I don't think they actually run cables like that, but it probably looked better to have cables visible in the picture.
dx034··on Popover API
If any click outside of the ad dismisses it, it'd be much more user friendly than many current implementations. I guess advertisers will stay with current solutions where you have to find a tiny x to close the ad.
dx034··on Millions snap up new Germany-wide public transit ticket
That can be much more expensive as it won't automatically find the cheapest option for day passes or multi-day passes. And it's not very convenient to look up and pay separately for every ride if you visit a city and travel a lot.
dx034··on Ways to shoot yourself in the foot with Postgres
Maybe they'll change it at some point. I believe if SQL Server was free, it would dominate the business. I last used it 7+ years ago and back then it was (from my subjective experience) better than Postgres is now. And I love Postgres. But SQL Server was a dream to work with. Feature rich with amazing tooling. You can get most features in Postgres with plugins and manual work, but SQL Server does it all for you.
dx034··on The Disappointment of 5G
but which really remote area gives you 5G with 1ms latency? If it's worth to have that infrastructure you might as well have fiber at home.
dx034··on Google Cloud region currently down due to water intrusion
Wasn't there also this technique of lowering oxygen levels so much that humans can still survive but fire won't spread as fast? Or did this turn out to be too expensive?
dx034··on The Disappointment of 5G
In remote areas, Starlink is probably a better bet than 5G to allow for low latency, high bandwidth use cases.
dx034··on Ways to shoot yourself in the foot with Postgres
I second that. I found it by far the most pleasant database to work with, including its tooling. Postgres is probably second. Too bad SQL Server is so expensive.
dx034··on Meta is about to start its next round of layoffs
While you cannot fire everyone in the same second, you can have batches over a few days. There's no need for waves that span over months. If anything, the risk of IP theft is much bigger if people have weeks of uncertainty if they'll be affected by the next layoff.
dx034··on Meta is about to start its next round of layoffs
And attrition reduces the number of underpaid people, while you'd want to reduce the number of overpaid people.
dx034··on Shutting down my legal torrent site after 17 years
For businesses it is not. I don't think there are any countries where banks don't use blacklists that go beyond legal requirements.
dx034··on America’s $800B climate splurge is feeding a new lobbying ecosystem
Honestly I think lobbyists are fine as long as their influence on politicians is tightly controlled. A politician needs to know the interests of companies and people in their constituency. Lobby groups are an effective way to provide that view point. They just shouldn't be allowed to write laws or bribe politicians.
dx034··on CATL has announced a new “condensed” battery with 500 Wh/kg
I believe car manufacturers are already big in battery production, for them it's as crucial as ICE production was before. It takes time to ramp up but I'd expect battery tech to be a key component that large manufacturers will want to have in house. But it could be one of the first key technologies where Chinese companies are a few years ahead of European and American companies.
dx034··on CATL has announced a new “condensed” battery with 500 Wh/kg
But do we really need to focus on general aviation? I don't have numbers but believe it to be a pretty small part overall. In transportation, it's also fine if we keep some gasoline speciality vehicles for a long time, as long as we're able to convert the vast majority of cars and trucks.
dx034··on CATL has announced a new “condensed” battery with 500 Wh/kg
Recharging would take a lot of energy but it's not unthinkable to have 1-3 GW supplied to an airport (which is what a reactor would likely supply), large metropolitan areas and large industrial factories already get to similar amounts. It's a couple of transmission lines and most large airports are close to population centers anyway.

The challenge would be getting the right amount at the right time, like now with quick charging. Like there, you'd probably have buffer storage at the airport so that it consumes electricity when available (e.g. during the day from solar) and dispenses it to aircrafts when needed. Luckily, most airports in the world have nearly all take offs and landings during the day, so there's a big overlap. Dubai would be an example where likely all would come from solar but a lot is needed over night (if we ever get electric long-haul flights).

So overall I don't think that this would be the limiting factor. But I guess larger airliners are more likely to run on synthetic fuels than electricity for a long time. And I guess that's fine, we have a lot of areas where cheap and/or dense batteries can help us much more in the short term (grid storage, cars, trucks).

225 Wh/km is even high for most routes and cars. Unless you drive fast on motorways or in cold climate, it's often easy to get to 150 Wh/km (15 kwh/100km as often displayed).
dx034··on Starlink now available on lakes, seas, and oceans all around the world
If you look at maritime traffic [1], the size of the market becomes clear.

I guess pretty much any boat will instantly buy it. There's just nothing comparable and even with smaller crews, it's well worth it. It makes communication with vessels much easier, in addition to the advantages for the crew.

I wonder if cruise ships will install several of those to provide internet to all passengers?

dx034··on Google reverses 5M file limit in Google Drive
Because they probably hired a third party supplier that gets money every month to make sure stationary cupboards are filled.
dx034··on Ask HN: WWYD? Built a company valued at $1B and may walk away with nothing
The safest way would probably to find a way saving ~10% in cost through all means necessary while keeping revenues stable. If that's somehow possible, you stop burning cash and are not reliant on external investors anymore.

Maybe ask your employees? I'm sure they also don't want someone to come in and take control. And quite often, employees can think of creative ways to save money that the CEO doesn't know of.

As you describe your situation, your COO would be the perfect candidate to find that money.

dx034··on Tailscale Funnel now available in beta
Are there really Microsoft accounts that were terminated out of the blue? I always had the feeling they acted a bit more responsibly around that than Google.
