To answer your question regarding commonality/ready availability -

Carbon, Nitrogen, and Iron are cheap and easy (you’re likely within body length of a large quantity right now). 32% of the earths mass is estimated to be Iron. $1/lb or less in massive quantities.

Nickel and Molybdenum are slightly harder to find, but not by much - nickel makes up 1.8% of the earth by mass and is a reasonably common metal in everyday manufacturing. It’s currently at $3.97/lb spot price at tonne quantities. Moly is in everything from greases to steels, and while typically not used in large bulk quantities alone, is available for such [https://tradingeconomics.com/commodity/molybden] at looks like $23/lb give or take.

So all commonly available elements, albeit (nanotubes) not necessarily in the form desired just yet.

What makes NFTs better at either of those applications than just a database? Ticketmaster is garbage, but I can't say I've ever had any uncertainty about whether I owned a concert ticket. And titles/deeds are perfect examples of why NFTs are worse than the current solution. I don't want my house getting repossessed because I got hacked.

Easiest is to make marketing to works for you.
This will take time (from 6 months to year), but once you finish this then growing can become like 10%/month.

How to do this - long story but can be outsourced initially. This can be content marketing, SEO, PPC, social networks ads, etc.

THIS IS EXTREMELY IMPORTANT step! I've seen many SaaS that they're "too good and do sales w/o marketing" and fail spectacular once marketing oriented competitor(s) enter on same niche.

Step #2 - it's finding good sales oriented person. Because good salesmen can sell anything to anyone.

Connecting that two dots can make a growth like 20-20% per month or even more.

Disclosure - i'm technical SEO oriented dev. One of best example i've involved is growing Ecommerce site from $50k per month to $250k per months just for 6 months. Today they make some like $500k-$1M per month or even more.
I think GP is suggesting it in other places, like replacing:

#+STARTUP: indent
#+OPTIONS: ^:nil

With something more like:

{ "STARTUP" : ["indent"], "OPTIONS" : { "^":null} }

That is, not using it to markup the document proper, but to encode all the various metadata bits in a more uniform notation.

I disagree that it's less clunky than the present situation, but it may be more consistent. I mean, you'd still need something to mark that some JSON follows and is separate from the other text in the document.

#+CONFIG: <JSON String>

S-expressions would make more sense, if we're sticking with emacs lisp anyways. But would still be clunkier than the current system at least for writers. Maybe better for people trying to implement org-mode (fully) in other systems.

What context are you accusing him of leaving out?
> Wait, you're now using "cancelled" for "people know what you said and don't want anything to do with you", and suggesting that this is a problem?

Yes, it's a problem when it's to the point of completely disassociating from you given the opportunity to do so, and the comment was made outside of work, in a completely different forum, and not to them or about them. They're not willing to engage with you and try to change your mind, or even just to continue working with you (without being forced). They're jumping straight to outright ostracism, or as close to it as they can manage. And anyone who doesn't do the same is next in line—guilt by association is a big part of cancel culture. Often it's not about what you did but rather about your failure to publicly condemn and "cancel" someone else for what they did (or perhaps only have been accused of doing).

I'm not saying they should just ignore whatever specific thing it was that gave offense, though sometimes that is the right approach in a professional context. Choosing to working together while ignoring irreconcilable differences is sub-optimal but better than not associating at all. That, however, is something that people should choose for themselves, not something they should be forced into.

> Implicit in this is the claim that people don't already do this.

I'm sure some people do, and if they don't feel that they can continue to associate with someone based on what they've personally done then I support their choice. In the vast majority of cases, however, a more measured response is warranted which doesn't involve burning all bridges and driving the offending party into the outer fringes of society where they are likely to encounter others who were similarly exiled and become ever more entrenched in their positions.
I'll note that the "Semantic Web" was the first contender for being "Web 3": https://en.wikipedia.org/wiki/Semantic_Web

I also don't get this term "full frame". When I started photography, "full frame" was 120 format. 35mm was "compact camera". And I think you need to go to 120 (at least) to do noticeably better than Olympus micro four-thirds.

holy shit - i'm in the shit right now. deep deep shit.

my method is something like spray and pray, ping friends to see if their companies are hiring, target certain companies if they doing something interesting, put myself out there on HN and Linkedin, etc.

fuck. me.

6+ weeks now of going hard core, and nothing yet.

i bail on quite a few possibilties, but i've also been bailed on quite a bit. like, 2 of 3 people on a video call are cool with me, but one hates my life. what? i'm def hate-able, but if you're so sure you hate me before we even get on the phone, why waste my time?

some companies have pretty big processes. i talked to stripe recently. i was like what's your process like?

they're like...

1. one hour live coding session
2. homework
3. 4 or 5 one-on-ones
4. something? might be nothing here.
5. offer
6. ref check

only 'weird' thing about this interview was it was kind of surprising to me in that, how it started - this was just a screening call - felt good/sane - pleasant recruiter, good questions, etc. - but hearing about that process, i had to nope out.

the live coding interview is a bit over the top, i think, but at least they have to waste their time too for that hour. but an hour? it takes you an hour to know if someone can code? you have to live code to know if somebody can code?

this is for an advanced tech support role, so while it's not 'sustaining', presumably it'd be heavy w/ api and whatever tools/languages/environments, thus...the need to spend 60 minutes typing in front of someone. i think that's awkward and overkill, but if one of the purposes of interviewing is establishing fealty/submissiveness/desperation, then it makes good sense.

then the homework. i just added this note to the top of my resume the other day, to help me weed out homework companies -- prob after stripe got my resume, unfortunately:

No homework, please – happy to spend time on the phone with your tech screener. My AWS Cert is here. My side projects are here. My public github repositories are here; access to private repos and university transcript available upon request. Thank you.

eh.

my resume is trash, as i suspect a lot of wantrepreneur resumes are, but this job hunt thing is not so fun when you actually need a job.

i still think there is some better hiring model out there that we haven't gotten to yet. unfortunatley, it's probably called "a real social safety net" -- so we don't have to worry about that happening in America anytime soon.

Did you have three votes, or more than three? If you had the same number of votes as there were positions to be filled, that's a plurality block vote. Winning slate takes all.

> RCV, once someone has gotten their candidate in, their vote is exhausted.

Hi, Australian here. What happens with multi-winner single transferable vote is that there's a _quota_ and then ballots for candidates who have reached quota get _reweighted_ (not quite the same thing).

This quota-and-reweighting system can (and must!) be applied to multi-winner Approval too - jpfed linked the wiki article.
>>One Mafia family has functionally unlimited power, and verifiably censors the two other groups worldwide.

>There's a media blitz about Facebook precisely because Facebook doesn't have unlimited power,

B-b-but I thought Facebook wasn't one of the Mafia families? I think you're just saying words for funsies.

>The media, the government, and the mob can fight Facebook on terms that give them a meaningful chance of winning.

Talk about willful blindless. The global right-wing induces Facebook to censor LGBTQ+ stuff in much of the world. They are not a Mafia family, competing on an even footing with others. They accomplish their deplatforming in ways that black people and LGBTQ+ people simply cannot. Read the article. Facebook can, and does, do whatever it wants -- it just so happens that that coincides with what one of the Mafia families wants. But not the others.

Your fantasy about mob justice being a credible threat to a poor shivering multibillion dollar corporation doesn't actually accord with the facts. Why not stop wasting time moving your goalposts around and answer some of the quite reasonable questions elsewhere in this subthread? What about the New Zealand shooter? Freedom of expression, right?
It is one of the most limiting factors for solar, when everything is accounted for.

You either put it really far away (increasing transmission losses and right of way issues for the much longer lines), or you put it closer and then have to deal with expensive land or difficult environmental reviews.

It is not AS BIG of an issue as it could be - for instance 30% efficient cells vs 23% efficient cells, the lower efficiency’s cost vs space usually favors the lower efficiency, but it’s still very strong overall.
It doesn't take that much. If you're good enough at DNA build from oligos, could probably synthesize it with less than a PhD. It is expensive though, and very unlikely that anyone would actually do it in a way that evades the surveillance systems.
You are right about Perlubie and Python being scripting languages but unfortunately people use them for full applications that use 10 to 100 times the memory and CPU of what is necessary. Now C and C++ are the other side of this coin where they could be 10 to 100 times more efficient than scripting languages but it is often difficult to get that right without a lot of work. But there are a number of languages in between where doing the correct thing is easy and CPU and memory efficiency is close to or on par with best C and C++. So we can have nice things after all!
That’s weird, was this article edited after being on the HN front page a few days ago? I distinctly remember the article mentioning social networks being built in SF in South Park, but now that section says “ I have vivid memories of the ferment of the late 2000s, a new social network flaring up every week! I lived in San Francisco; they were building them in offices around a narrow, scraggly park” which strikes me as odd phrasing.
His luck was that his set of dna and experiences made him land a rich tech job and made him smart enough to live in a Low Cost of Living location.

> it has really poor energy/l

Compared to fuel yes. Compared to batteries, even at relatively low pressures, I think hydrogen still wins even by volume, and at higher pressures it's an order of magnitude difference.

> In Europe, battery powered trucks can carry a heavier load than diesel trucks.

You mean legally? If we're discussing which option is technologically superior long term, then it doesn't really make sense to argue based on arbitrary laws today. Is there a particular retionale behind the law that would make sense for electric trucks but not hydrogen ones?

> Green hydrogen is always going to cost about 10x as much as electricity.

Possibly, but as more renewable energy sources come online, the problem is going to change from "can we produce enough energy?" to "is the energy available at the right time and place?". Electrical energy is very difficult to store and transport in any significant quantity. We already have to turn off renewables sometimes because they're simply producing too much power when we don't need it. That power may as well go to creating hydrogen than doing nothing.

I don't know that hydrogen specficially will be the long term solution either (after all, something better could always materialize) but current battery technology is definitely not a panacea.

> ... is necessarily a lot less efficient than using than skipping 4 of those steps to charge a battery directly.

High battery/payload weight ratio means you need more energy to get where you're going, which is not typically considered when comparing the efficiency of batteries to hydrogen. Batteries also take a lot of energy to manufacture in the first place, and have a limited lifespan, which is also rarely considered. I think that with some minor efficiency improvements to a couple of steps, and a lowering cost of electricity at "off-peak" times, that the overall equation will shift.

> And truckers don't care about fuel density, they care about costs.

Costs come from a lot of places. Trucks sitting around charging instead of delivering goods are a cost. Reduced range means increased costs. Expensive batteries that have to be replaced every X years are a cost.
If you want a programmer/documentation approach then GitHub and developer forums are where you will get the best shill free discussion, read the eips/ercs on github and the eth cat herders forum.

> Li-Ion will never be light enough for a serious airplane

Not everybody agrees with that. https://en.wikipedia.org/wiki/Electric_aircraft#Commercial_p... says over a hundred electric designs are in development.

Very cool, there are definitely use cases where batteries are necessary (like moving vehicles) and it’s great to see advancement in battery tech.

EDIT: These batteries seem to be even less energy dense than Li-ion which is one of the weaknesses of batteries in comparison to hydrogen.
This idea, "Armor you buy in Call of Duty is useable in Battlefield", to me illustrates so much that is frothy and unrealistic about this space.

Think about what it would actually take to implement such a thing:

- Call of Duty and Battlefield - rival games from rival companies - would need to agree to an integration at a VERY deep level

- They would have to share the same asset formats, such that an asset designed for one game could be used in another

- Issues of balance would have to be resolved: just sharing 3D models wouldn't be enough, they would need to agree on a system for modelling damage, armour piercing capabilities, visual effects...

- Then they would have to add blockchain integration deep enough that weapons a player obtains in the game are represented in a way that the other games can see.

- ... not to mention figure out some kind of exchange rate / add some kind of additional economy to their games, which would need to be shared across different games such that e.g. a pistol in Battlefield wasn't worth the same as a machine gun in Call of Duty

That's just off the top of my head.

And... they're supposed to be games! Game design is about balance - creating a set of rules that players enjoy.

Allowing some cryptocurrency-billionaire to jump into any game they like with the best possible guns and armour doesn't sound any fun at all.

Pretty much every idea I see coming out of this space has the same problem: it sounds plausible in a high-level hand-wavy, but collapses the moment you start to dig into the details of how it would work.

(My absolute favourite bad idea is still real estate on the blockchain, where presumably if I forget my password I can no longer sell my house)
Wait, a colony on Mars by 2050 that doesn't need to be resupplied from Earth? ...lol no.

Strong, strong disagree that there will be any kind of "colony" on Mars by 2050, and my prediction is that we won't even have our first manned mission to Mars this century.

We haven't been back to the Moon in 50 years. We haven't left LEO in 50 years. Surely we would need to build a colony on the Moon first, as a trial for building a colony somewhere that's three orders of magnitude farther away. We are nowhere close to doing this.
What DeBoer describes is unambiguously a lie.

Whether some individual is actually doing what he describes has a lot more room for ambiguity.
> if we have a kind of nucleus that undergoes beta decay, and we built the exact same nucleus except out of antimatter, it would not undergo beta decay. Is that correct?

No. Until 1964 you would have been told that applying CP, i.e. the combination of C transformation (charge conjugation, i.e. change the signs of all charges) and P transformation (parity, i.e. swap left and right) would result in exactly the same decay rate. You would get anti-neutrinos (which are right-handed) instead of neutrinos, but that would be the only difference.

Then it turned out that CP symmetry is also violated by weak interactions, though far from as neatly as just P:

Apparently there are also some major patents that have expired or are expiring soon, which I hope means that costs will drop and we'll start seeing more LiFePO4 battery manufacturers outside of China where the vast majority are made now.

Somewhat ironically, the person I spoke to actually calmed me down enough to allow me to go and call on a friend. By the time the authorities arrived I was in a much better state. All they did was waste resources and reintroduce my negative thoughts.

I called them to be anonymous and not disturb my family, so I could get into a calmer state where I could get help from my loved ones. They utterly failed.

Fair enough, I should have just called it cache.

The point remains though. The ZIL is not meant to be a cache. The SLOG (which is a "ZIL on a separate device") could be viewed as a cache, but it's a cache for the ZIL. Thus being a cache for writes is incidental, not the primary purpose.

Certainly, if your workload aligns with those conditions, then you will experience a performance boost. For other workloads it it won't help and for certain workloads it can even be detrimental[1].
