blablabla123··on Ask HN: Anyone else feels the commoditization of real estate is unethical?
There's definitely a need for creative ideas. But also thinking about AirBnb I don't think this can come from the private sector.

That said I don't get why people don't invest in something else. There are some many different assets, using real estate to squeeze out a few percent every year on average seems a very weird thing to do. If landlords feel they get screwed over it's exactly because the margins are so thin.

blablabla123··on Study finds link between 'forever chemicals' in cookware and liver cancer
Most yes, although the far higher intensity was near chemical plants through the water supply I think especially in the past.
blablabla123··on The semantic web is dead – Long live the semantic web
Wikidata is quite usable though with SPARQL through REST. To me the biggest problem seems lack of documentation but for small scale experiments interesting stuff can be done with it (with enough caching, probably with SQL). Running my own triple store seems a lot of work though, already choosing which one to use actually
blablabla123··on Noether's Theorem in a Nutshell (2020)
It might be easier to think about the Hamilton function H which is basically the Energy E=T+V...but as a function of p and q. H can be converted into L=T-V using the Legendre transformation. L is what people use to proof all this stuff
blablabla123··on The problem with Go’s default HTTP handlers
Seems a rather theoretical problem to me because usually an external library is used. Also in the underlying http response first the return code is written before the body. This matters a lot when for instance copying a buffer into the response
blablabla123··on Ask HN: What's the next big thing that few people are talking about?
Actually the current state of the art of H2 is fundamentally safe so to say, e.g. it's wrapped into some sort of oxide. But the most important cars on the market (of which there aren't many types) still use the 1st gen approach which is a bit unsafer.

I think there are solutions to the show stoppers of H2. But the package isn't very appealing, at least not for individual transport.

Also what makes EVs appealing, they've reached a state of convenience that makes them feasible for most use cases. And for the rest it seems some hacky solutions are possible.

Of course the waste of switching from ICEs to non-ICEs will be incredible. But well, hard to see any alternative..

blablabla123··on Ask HN: Longevity for your parents, what to do?
I think you better ask a food expert or at your local pharmacy :) I mean if there is serious concern they are low on certain nutrients, they should make a blood test. Then it's possible to change the diet if needed or add food supplements.
blablabla123··on Ask HN: Who do you talk to about system architecture and design?
When I was co-founding, at points of time as only tech person I usually went to the SE network. In that case softwareengineering.stackexchange.com. It's quite good but of course the question format needs to be kept otherwise nobody will give a full answer... (Also I think the process of writing it up alone sometimes solves some uncertainties) In the comments sometimes actual discussions come up
blablabla123··on Ask HN: Working in tech for climate?
Worked in that space for a while and found it through a Recruiter on LinkedIn. Generally I think the average salary is a bit lower but now there are a lot of Climate techs which to my understanding work like Fintechs. There is everything from solar tech to CO2 budgeting systems. Surely it has an impact although of course the companies are still businesses so not everything they do is for a greater good
blablabla123··on “After Going Solar, I Felt the Bliss of Sudden Abundance”
I'm on a plan that uses only regeneratives, that also definitely helped me stop worrying too much (Although now there's the gas crisis unfortunately)
blablabla123··on Ask HN: As a dev manager, how do you deal with a prima donna?
Rewriting is quite an effort. It's a no-brainer when the existing code is buggy, slow and it's acknowledged by everyone that it needs to be done. On the other hand, not rewriting might mean nobody wants (or is even able) to work on a particular code base. Postponing it too much in the future can mean the project fails and if management doesn't understand in time there's a problematic code base that means devs have no support for what they do. From OP's description it's not possible to see if there are any objective points for the quality of the code (e.g. linting, test to code ratio, uptime)
blablabla123··on Deutsche Bahn’s Meltdown and High-Speed Rail
Yeah, going from Frankfurt with the ICE is almost like taking the taking the bus around the corner. They definitely did something right there
blablabla123··on Ask HN: What is the job market like for niche languages (Nim, Crystal)?
The jobs where niche language are used (not necessarily exclusively) seem to me more interesting but might bring other downsides like very small teams. Also if you used such languages previously, chances are the next place you start turns out to also use a niche language somewhere or be open to it. The most uncommon tech is usually not even listed in the job ad and will only be seen a few months into the job...
blablabla123··on We're going to need a lot of solar panels
> With all due respect these are the kinds of "tiny" details that renewable enthusiasts conveniently forget.

I mean generally it is well known that you cannot just put a lot of PV/Wind and things will work. A smart grid is needed, buffers and ideally great insulation although that is arguably important for every form of energy. Also at-home PV setups are meant to earn money/offset the energy bill. Autonomous energy supply is an after-thought that is interesting enough but has obviously not been possible with any other energy source before actually.

blablabla123··on Blockchain.com cuts 25% workforce amid crypto bear market
IMHO the importance of currencies is getting highly inflated. It's just a tool and if the real economy is not going well - or the part that is actually mapped with the currency anyway - then the numbers don't look good. I'm not sure about the zero sum game part but I highly doubt changing the scale (which is what Bitcoin for instance does by limiting the max. amount of coins) is changing the dynamics
blablabla123··on Sound of Colleagues
Same for me. I mean for really difficult and focussed work I prefer a very quiet place but for rather standard work an open space is perfect, keeps me from falling asleep
blablabla123··on The Uber leak exposes the global war on workers
I'm not a frequent taxi user but to me it's the most reliable mode of transportation which I always have as backup in mind when I need to get somewhere really on time. The additional luxury is cool but probably I'm fine without it, it puzzles me how dissatisfied some people are with taxis
blablabla123··on Uber broke laws, duped police and built lobbying operation, leak reveals
> Basically every US company operating in the EU is breaking GDPR post-Privacy Shield right now

No expert but in New Relic you can select in which data center your data should be. In fact many websites of US newspapers are not accessible from the EU. Just recently I had to order a gadget through reship.com because I couldn't buy it directly...

blablabla123··on Is the smart grid all hot air?
That would be especially interesting for hours with negative energy prices (at least once they become accessible for retail customers). Also various appliances like washing machines or dish washers can be timed
blablabla123··on Nuclear turn green as EU parliament approves new taxonomy
I mean there's a law for coal power in Germany, already since decades but the new add-on codifies that. They might be doing worse than France in terms of CO2 emissions per capita but far better than the US.

Since cost is mentioned:

"The cost of generating solar power ranges from $36 to $44 per megawatt hour (MWh), the WNISR said, while onshore wind power comes in at $29–$56 per MWh. Nuclear energy costs between $112 and $189."

blablabla123··on Nuclear turn green as EU parliament approves new taxonomy
I know, that's why I wrote "renewables". Comparing with one of several widely deployed options seems a bit arbitrary
blablabla123··on Nuclear turn green as EU parliament approves new taxonomy
I'm aware of that and it's summed up together with hydro etc. Why would you want to compare Nuclear with solar? I mean solar alone doesn't make much sense because it depends on daylight - which surely is great since most energy is used during the day and battery storage is getting increasingly deployed. But it's better to diversify and therefore rather consider the sum.

> 25% of the total was from coal, making coal the single largest but source for energy in Germany.

Well yeah but it's getting phased out on the long-term.

Edit: also it's worth considering that gas and bio gas (the renewable version) power plants can be used during peak times because they can be started and shutdown quickly. That's not possible for nuclear which provides base load - in fact they need to be shut down during heat waves

blablabla123··on Nuclear turn green as EU parliament approves new taxonomy
> In 2021 the 6 remaining nuclear power plants produced more power than all installed solar capacity in Germany. 3 were closed at year end.

65 billion kWh from Nuclear and 220 billion kWh from renewables actually

blablabla123··on Nuclear turn green as EU parliament approves new taxonomy
Environmental sciences are still a niche and the storage problem hasn't been solved yet. E.g. the infamous Asse II has empirically proven to be unsafe mostly because of water influx and the 126.000 containers (which are partially captured within slowly floating salt) now have to be retrieved which is going to cost billions

No insurance company in the world is willing to insure a nuclear power plant and both risk and operation have been heavily subsidized since decades.

In fact renewable sources are even cheaper:

"The cost of generating solar power ranges from $36 to $44 per megawatt hour (MWh), the WNISR said, while onshore wind power comes in at $29–$56 per MWh. Nuclear energy costs between $112 and $189."

blablabla123··on How normal am I?
Same, but I think people generally over-estimate how much different from average they are. (It's from the webcam's pov anyway) Usually I also don't like interactions with the webcam but this was interesting enough.
blablabla123··on The crypto crisis has created an advertising vacuum
Yeah being purely positive or negative isn't any good. Although BTC shouldn't be benchmarked with Airbnb but with USD/EUR...

Bitcoin itself isn't a scam, in fact it has (or had) really ambitious goals. But the dynamics in the last years are quite scammy because not many things are bought with BTC. Maybe PoS will bring something new

blablabla123··on Ask HN: Want feedback on LinkedIn alternative
I think so. I mean I can definitely imagine situations where it's preferable to network with a work email especially when working in an early stage startup. But at a regular Software Engineering job I'd probably go with my personal email
blablabla123··on Ask HN: Want feedback on LinkedIn alternative
> Users will need a work email to register to validate their company

This would prevent me from using it, already for the reason to really separate work and non-work. Also I think apart from a few conservative BigCorps, nobody really cares about formally verifying the CV e.g. based on past certificates.

blablabla123··on Ask HN: Europe to East Coast, does it make sense to move at 50?
I think you could say this about many regions in the world at the moment to be fair. Covid has made a lot of simmering issues escalate all around the world.
blablabla123··on Stack Overflow Developer Survey 2022
I kind of want to like Angular since it's so nicely integrated. But working with it is clearly not fun...
