> do you need to to become a mad-scientist electrician and DIY?

I did my own a couple years ago, and it worked quite well on the first go. I got someone else to build the LiFePo4 battery pack (16 CATL cells for 48v with a JK BMS).

It was fairly easy to build. Mount panels on the roof, and wire everything (PV, battery, grid electricity if you want it, and the output) to the inverter. I added some extra steps to monitor usage and output, and a smart MCB. I also have a small shop that I can feed from solar power if the battery is almost charged and the sunset time hasn't reached yet.

See if you quotation is to export electricity to the grid. Those kinds of setups usually require a certified company to do the installation (to make sure the inverter syncs with the grid), but for off-grid setups, you can definitely DIY.
ah right, it starts that way, been a long time already
This is in the american southwest so winters are very mild and the sun is still strong. Summer is the much more demanding part where AC is 90% of electricity use for the year. There would certainly be challenges in other locations but I think you could do the napkin math on it with panels being as cheap as they are. The solution to pretty much any deficit these days is to just add more panels. The biggest issue there is, is if you do not have sufficient space. My panels are ground mounted.

As an opposite data point, when I was looking for a job I interviewed with multiple companies that I found on HN who is hiring. And one of them ended up hiring me. Two years later I work for them still.
Its funny, because professional transcriber will get the same words. But with better choosen paragraph breaks, and sentence splitting and dropping filler words where it hurts readability.

Hard to get right, it seems.
My guess: to throttle demand. Installers are generally in short supply and huge demand. So why not charge a premium?

In the 8 to 10 years panels will be even cheaper. Probably half of today. The price trajectory is still falling.
In total numbers I got 539 jobs saying that they want Rust experience and 695 want Go experience. I think I should have added another line-chart showing the programming language distribution over time, thanks for the idea.
I agree it would be much more efficient on the whole if the grid manages energy storage in bulk.

Unfortunately over here we have a monopoly awarded state owned power producer which has a history of incompetence and corruption.

Maybe at some point our grid can be trusted to be reliable, but in the meantime everyone is either installing their own batteries or having no electricity for hours at a time. Tragic, but what else can you do.

Umm… I think you are deeply misguided on this.

Earlier in life I created something that has generated a minimal stipend every month. That small security has enabled me to take risks, produce art, create technical processes, construct the water, power, data, and physical infrastructure for a private sustainable community, take a couple of years off to educate my children in technology, and, in short, prosper. It is life changing to know that the worst that can happen if you fail is that you will be mildly uncomfortable for a period of your choosing.

OTOH I see a lot of wasted potential, talented people working banal 9 to 5 jobs because they can’t risk failure, forgoing learning opportunities because they can’t take the time, and in general stuck in employment traps that prevent them from ever refining their natural talents.

Sure, some people will do nothing with their lives despite the opportunities presented to them… but many, many people would do much, much more if they weren’t trapped in a system designed to harvest, under duress of homelessness, the vast majority of their useful time in exchange for the lowest possible compensation.
Not really, you still need some system to distribute the shared key.

The paper's method suppresses original message then generates btand-new one, so if the key is easy to find out, then the spoofed message will have a correct MAC. Which means you need a cryptographically secure method to distribute the key, but you also have multiple consumers and you want to be able to replace broken devices too. This sounds like a non-trivial cryptosystem, and assymetric crypto + certificates is one possible solution.
From experience it seems to be semi-random.

I've never had a single spam call on my main phone number, but friends who have got a new number get maybe 20 spam calls per day, with only having given their number to their closest friends and family.

I think one factor that weighs in heavily is if your contacts download thousands of spam apps onto their phones and click YES to every permission. Then your phone number is harvested from your contact's phone and sold. TikTok, for instance, will beg me multiple times on a frequent basis to see my contacts. I don't think you can even install WhatsApp without giving it your entire phone book, can you?
As an intermediate point in the Require Reproducibility ↔ No Requirement spectrum, strong encouragement to have reproducible artifacts is attractive as well. I just got a paper accepted to ECOOP (European Conference on OO Programming; has lost it's OO-focus and is now a general PL conference) and it's trying something relatively new: artifact evaluations are considered as part of the submission process. Our paper had a reproducible and reusable artifact, and I think that helped our case with the reviewers.

Running through this in my head again and again, and editing 500 times along the way, apologies. I'm done now:

You believe that it is narrowly true gravitational wave researchers did this, like a kid saying they "wrote their essay" in response to whether they "did [completed] their homework"

I believe it is wholly true.

I believe we agree on the narrow truth that they are gravitational wave researchers.

I believe we disagree on the wider truth.

I believe you believe its a wider lie, in that it indicates they used gravitational wave-style techniques in this endeavor.

I believe it is widely true, because they're using the specific techniques that I saw astrophysicists use in grad school.

Is it possible you saw "Bayesian", assumed that was the extent of their expertise applied, then noted that it has no relation to their expertise, since that's entry-level stats, not physics?
US Reopens Historic WWII Airstrip Amid Rising Pacific Tensions
An "AIopticon"
Well, here, France, LFP batteries now cost MUCH MORE than just three years ago (final customer price) and... ~1000€ per kWh, while just 3 years ago they was a bit less than 700€ per kWh, the battery alone (with BMS etc) but we also need an inverter witch as well is not much more expensive and I talk about self-assembled systems, here legal, but not legal in large slice of the EU, because retail price of a complete installed system by some p.v. companies are so high that there is no economical reason to install them.

My system is 5kWp/8kWh @11.500€ three years ago, it would be now a bit different (400V batteries instead of 48V and a hybrid inverter instead of a p.v. string inverter AC coupled with a battery inverter) @~ the same price due to a single inverter and slightly cheaper p.v. modules (@~100€ for a 415Wp). If done by third parties the cheapest proposal back than was ~30.000€. At this prices given current electricity prices and local grid stability it's a nonsense, it's even cheaper a diesel generator.

I know prices in China are FAR lowers, and I've read also on far lower Thailand prices, but compared to local cost of life I can't quantify how much.

This seems like a decent force multiplier, though I have to wonder how efficient the results are compared to just having a small crew of workers with a boom lift and a good toolbox. There are also the attention-splitting issues you can't cover with just one person in a cab, like marking off areas and directing traffic/pedestrians.
Concurrency is not the same as parallelism. I’ve understood TFA to mean concurrency when it mentions parallelism. This would explain the presence of JS libraries which could test for concurrency problems in asynchronous code.
It's been a while since I literally laughed out loud at something I read. Amazing, thank you.
This is very neat! Thanks for using your time and literal dollars to work through this!

As an added detail regarding the "remote" v "in-person", another interesting statistic, to me, is to know how many of those in-person job-seeking companies are repeats! It could absolutely mean they're growing rapidly, OR it could mean they're having trouble finding candidates. Equally, missing remotes could mean either they're getting who they need OR they're going out of business.

All interesting plots on the graph!

This is a cool statistical paper, one of many depressing papers that makes me wish I knew more math. The "gravitational wave" angle is apparently that it uses some statistical methods that originated in gravity wave research. There are no ultra-sensitive new measurements or anything like that. They use the same X-ray measurements as the Clickspring article from a few years ago (https://bhi.co.uk/antikytheramechanism/) and basically support Clickspring's conclusion (that the Antikythera was a lunar calendar) with increased statistical confidence.
While this made me laugh and there is some truth to it, the nice thing when running the process described in the blog post is that you don't need to know what or how you want to count - the LLM has the knowledge to classify it correctly enough to get good estimations. Go and Rust are both good examples of words that have multiple meanings and are pre-/suffix to many other words.
Having a lot of cheap electricity is also a trope in an anarcho-syndicalist utopian paradise for all the people.

UBI and better healthcare would allow me the freedom to innovate. Right now it’s a much more significant barrier to strike out on my own and build something. So it makes more sense to me to just have a 9-5 job, but if there was a bit more wiggle room I’d certainly try it.
While NZ currently doesn't do much of that sort of thing, the European settlers of NZ simply couldn't get enough of telling other countries what to do and were fairly instrumental in drawing up and imposing borders after the fall of the Ottoman empire.

Did that work well? Should the west keep following a similar course of action?

I am also keenly aware that British Empire involvement started with conquering Palestine & The Balfour Declaration, and ended in the Sergeant's Affair. We have spilled more than enough blood for Zionism and (when we were no longer useful) had our blood spilled by Zionism.

Therefore I reiterate - do not make Iran your enemy on behalf of people who have historically used us as tools to get what they want.
I don't think that's right. For example, "veterans" are a protected class, but this is a category of past employment the same as "farmers" or "teachers".
This is very standard stuff in Finland for decades. And before heat pumps became popular large tanks were common and those were heated during the night.
When you say $89/kwh, are you talking about just cells, or assembled packs? I’m just about to buy a 5kw Lifepo4 server rack battery from EG4 for a diy project. It’s closer to $220/kwh

Well, that logic has always been the basis of big pharma's business model. And it makes sense business-wise - investors want to create and retain customers, not lose them.
You're doing extremely simple constant arithmetic here. GHC can optimize this type of thing away to nothing as well. Are we talking about contrived examples or real numerical bottlenecks?

I did not know that fireworks contained plastic (although I should have). However, please be aware that the health impacts of microplastics aren't really well known, which places this article in the "mostly scare-mongering" rather than "actual risk we should care about"; this is typical of the BBC these days. Of all the things that Americans do that are unhealthy, plastic pollution by fireworks is pretty low on the list of enumerable, measureable harms. While, fireworks and firecrackers are quite dangerous on their own for explosive reasons.

A better source would probaly be this observational study (https://www.sciencedirect.com/science/article/pii/S0025326X2...) and I was unable to find any high quality studies that showed any strong evidence of direct harm.

It (BBC) is just a low quality source for information impacting our lives, with an emphasis on dire-sounding, but poorly understood harms.
Many cross-platform applications which store metadata in xattrs on Unix-based systems will use ADS for the same purpose.

E.g. Dropbox, which syncs some extended attributes (and uses some for internal metadata), seems to store them in the ADS on Windows.
Sure, if you are one of the rare engineers who wasn't using Google search, or any sort of discussions or collaborations with other engineers in their day to day engineering workflow, then I can fully understand why a super powered version of the same thing wouldn't be useful to you.
In the UI, yes. But the functionality is already preset. It just needs a button and a progress bar.
>Apple should be stripped off this power. EU's DMA is a first step, but we need such policies applied everywhere.

What do you suppose happens when those same authoritarians make a reverse DMA and require that all phones sold be locked down only to a single centralized market place? If one thinks Apple should be complying (and bear in mind the amount of consternation there has already been around "malicious compliance) with EU laws and policies, I'm not sure how one can be consistent in thinking they should be ignoring Russian law and policies.

Don't get me wrong, in my personal opinion, Apple should not be doing business either in Russia or in China. At the same time, I understand that if they did that, it wouldn't be materially improving things for the citizens of those countries. The only win would be for Apple / Apple employees in not having to comply with laws that violate "American ideals." However, that same ethical stance would be just as applicable to the idea of pulling out of EU markets too if Apple felt that the DMA was against "American ideals." To my mind there are only two possible consistent stances:

1) Comply with all laws and policies of each host country, regardless of personal beliefs / attitudes, and apply why pressure and objections you can to change those same laws and policies.
2) Do not do business in any country where the laws and policies violate your personal beliefs and attitudes, and loudly refuse to do that business until such time as those laws and policies are changed.

The third option of picking and choosing which laws you will or won't be complying is of course an option, but it is not consistent, nor am I sure if you could trust Apple to do that if you already don't feel you can trust them to manage app access on their platform.
I wonder if the inevitable conclusion of this is further consolidation so like openai buys Reuters or something - AI companies end up also becoming the publishing companies because the only way to make money off of novel material is if it’s no there for all the AI companies to scrape up.

That he was killed by manipulating the data bus seems entirely speculative and exceedingly unlikely. If you have that kind of access to the plane you can plant a bomb or if you just want to down the plane Russia has potent anti-air weapons which trivially can take down a sub sonic passenger jet.

Yes. Friction is usually the limiting factor in mechanical systems. It causes a lot of heat, noise, stress, and wear on all interacting parts. It requires all sorts of messy approaches to mitigate, such as lubricants and bearings. Electricity is basically magic by comparison.
"Our democratically controlled communication infrastructure" honestly deserves to be deprecated and replaced with some kind of federated voice system that comes out of the IETF instead of the telcos. What kind of antediluvian nonsense doesn't use end-to-end encryption in 2024?

Have you ever noticed the complete lack of good options for unlicensed two way radios under $300 or so?

Seems like this could be a perfect platform for intercoms, with the right firmware.

2.4Ghz LoRa might be better, but ESP-Now seems like it would be a perfectly good walkie talkie.

If there was an end-user-ready version with a speaker, a mic, and a display, it could probably replace a lot of audio related devices, but even as is it seems perfect for a mesh belt pack intercom.
At $6343 [1] for 13.5kwh [2], seems closer to $500/kwh? The federal rebate does help substantially, but most folks should qualify. This # is closer to $400/kwh if you buy with solar, and $300 if you're buying a few instead of just one.

Re: car batteries, the difference between the rear-wheel drive and long range is about 20kwh (60kwh vs 80kwh), for $8K. That's $400/kwh and doesn't even include all the other trim differences like having dual motors instead of single.

So, it looks like reality is closer to $300-$400/kwh, depending. Not close to your ideal of $50/kwh, but still much better than $1000/kwh.
