You could run something like Facebook but in tiny shards. It would be better. And require 1/1000th of the engineering workforce.

hnaccount_rng · 7 days ago

You can't though. The problem is, that humanity is a web. Not a set of communities (at least on the scale of 1000s of people). And since those webs overlap you will either need to solve the overlap problem at the boundaries (taking engineering effort) or you will end up with essentially one big shard again. On the other hand, you really don't need to change anything on the backend. Simply limit the number of "tier 1" friends to 50, have a "tier 2" category for your 1000 and put everything else in "acquaintances" and split engagement between those.

The problem with that though is: You will generate an enormous amount of social friction "why am I tier 2, but (without loss of generality) Karen is Tier 1?" and reduce monetizability. So truly nobody will feel happy about those restrictions. And since it doesn't solve any engineering problem you run into (see above) there is no one incentivised to build such a thing. (Ironically this may not be completely true, given that this is pretty much how Chinese social media apps work. So maybe states [or at least power structures] are incentivised to build such a system)

So far I haven't met anyone there who was into politics. People there are sometimes slightly anarchic, but definitely not interested in any left and right. But there are a lot of furries - the biggest visible group of visitors - they're just there for sex and party.

As far I can tell only some of the organizers (the people with the money for equipment) seem to have some ties to the fascist left. (Nowadays called Europe Socialism - they absolutely don't like Europe Socialism being called National Socialism - Europe is absolutely not National... But they don't really do anything that looks like CCC - they just spend some money there - and put a little bit of fascist propaganda on display...

Then you have ignored the majority of the event. Don’t get me wrong, I’m also there for the technical talks or at least tech-related talks. But most of the tracks aren’t that.

And I would say at least 50% of the assemblies and Co are political. The Sea Watch people, the ones who are regularly detained by Italian authorities have their home base there.

The CCC, as an organisation, always has been a political organisation first. I wouldn’t call them a particularly successful one. But they are the opposite of agnostic or worse apolitical

You really may want to look up where and how CCC was founded. I’m always amazed at people being shocked that left to extreme left politics are the norm on an event from an organization that was founded in Kommune 1 in hippy Berlin

Though they are also poised to get iron ore refining to work. That alone could be worth a bunch (numbers assuming 20y amortization and 30% average duty cycle (using only summer surplus) suggest around 10ct/kg iron metal capex plus 3 kWh/kg iron metal electricity).

How do these numbers compare with traditional methods?

Weirdly enough I have the opposite experience where it will take several minutes to do something, then I go in and debug for a while because the app has become fubar, then finally realize it did the whole thing incorrectly and throw it all away.

And I reach for Claude quite a bit because if it worked as well for me like everyone here says, that would be amazing.

But at best it’ll get a bunch of boilerplate done after some manual debugging, at worst I spend an hour and some amount of tokens on a total dead end

hnaccount_rng · a month ago

Yeah that is kind of my experience as well. And - according to the friend who highly recommended it - I gave it a task that is "easily within its capabilities". Since I don't think I'm being gaslighted, I suspect it's me using it wrong. But I really can't figure out why. And I'm on my third attempt now..

I calculate it at 52 cents per panel (40 lbs a panel)

Source for the cost:

https://docs.nrel.gov/docs/fy21osti/74124.pdf one study found that disposal tipping fees at non-hazardous landfills ($26/U.S. ton) can cost less than $1 per module and less than $5 per module at hazardous waste landfills ($175/U.S. ton)

hnaccount_rng · a month ago

Wow. I did not expect a single panel to weigh 15+kg. TIL

At the end of the day an LM is just a machine that talks. It might say silly things, bad things, nonsensical things, or even crazy insane things. But end the end of the day it just talks. Words don't kill.

LM safety is just a marketing gimmick.

We absolutely regulate which words you can use in certain areas. Take instructions on medicine for one example

The idea that we'll have huge excesses of clean energy seems like wishful thinking. We may have issues with excess energy at certain times of day for sure. But intermittent excesses like that are difficult to make use of economically because of capital costs and low utilisation. A general excess would be countered by falling energy prices to the point that it's difficult to make a business case for new installations.

I don't see a future where technologies which are massively inefficient reach their break even cost before other energy intensive activities or more efficient grid scale storage soak up the excess.

hnaccount_rng · a month ago

Of course it seems like wishful thinking! Because that’s the historic norm. Energy was (in some way) always the limiting factor. And every time energy access got meaningfully cheaper society massively reorganised around it.

And yes “energy” in general won’t be free. We still need to build the generation and distribution systems. But we reached a point where just dumping solar on all _new_ roofs rounds to essentially free (the costs are the labor and the access to qualified personnel). The exact same is currently happening to batteries. Any transformer project will be able to just integrate 4-12 hours of batteries without getting meaningfully more expensive. The same for every domestic or industry service upgrade

We are not there yet. But give it another 5 years and we will. And then we are only talking about financing what little distribution system we will need (basically you only need average-sized cables not peak-sized ones) and a capacity market for backup power systems (also only for average residual demand). And those we simply cannot (efficiently) finance by a per-kWh-used charge

Most applications could probably get away with not supporting control characters in paths, even git, because most file systems/OSes doesn’t support it anyway, as a user of control characters in a paths you can never trust it to work anyway.

hnaccount_rng · a month ago

_I_ would agree with you. But I’m also not a person writing a version control system for a kernel that still runs wrong-endianess hardware (I forgot which one we are using and can’t be bothered to look it up). And I think a major part of this is, that I assume that something is so insane, that people just shouldn’t do it and the people steering the kernel or git don’t (get to) assume that

The Russian government didn't see it as a Russian dependency on Germany.

As far as the dependency direction goes, Germany didn't start a war with Russia, so the simplistic example isn't enough to disprove anything. If you want to disprove it, do so by explaining how Russia was dependent on Europe.

Then go back to the beginning of WW2 and look up the biggest trading partners for both Germany and France
