It’s my understanding that the plastification of paper to make it waterproof is worse, ecologically speaking, than just using straight up plastic.

How do we wrap all the dairy, meat, and whatnot at the grocery store? How was it done 100 years ago? Heck, how was this done 200 years ago?

A Bitcoin ETF is literally the antithesis of the crypto project. It’s a centralised, highly regulated trad-fi product.

Also, no one is going to end up accidentally investing in crypto, these ETFs are going to be super niche products.
I really like this purifier's big brother, the IKEA STARKVIND, which is available in both regular[0] and table[1] versions.

The table version is nice because, assuming you place it somewhere you want a table, it takes up no room. The regular version is awkwardly large, so placement is a bit more of a challenge.

The killer feature for me is that its air quality measurements and controls are all exposed via Zigbee, and it works very well with Zigbee2MQTT and Home Assistant.

Related to this, IKEA has recently brought out the VINDSTRYKA[2] air quality sensor. Unfortunately the PM2.5 measurement (as reported by Zigbee2MQTT/Home Assistant) doesn't seem to match up with the same measurement reported by the STARKVIND. To be fair this is just a feeling, I have NOT conducted head-to-head testing.

They push very aggressively for whatever new TV series / movie they just released that is "top 1 in your country".

Spotify is the same with whatever crappy playlists and podcasts they want you to listen.

YouTube doesn't even bother showing results that you searched past the 10 or so results, it's "content you might like" which is crap and unrelated to anything I've watched, 100% of the time.
Ask HN: Good tools to block websites/apps to focus?
I've been always fighting against becoming a dopamine-monkey, and how literally every app tries to get you addicted to it.

I'm wondering if there are any good tools where I can do this also whilst using multiple devices.

I've previously used self-control for Mac, but nowadays I have too many devices.

I don't mind to pay money for it. Tips?
Do you have any links to those studies? Because the ones I've seen indicate the exact opposite. You only need 2-3 days of storage or so at most.

Tony Seba has some presentations on this topic. His argument is that renewables is getting so cheap that you can build so much that the minimum production covers all days with few exceptions. I guess that might assume some reasonable grid upgrades as well.

Marc Z Jacobsen has some fairly detailed studies for going 100% renewables. He doesn't generally assume any improvements in technology, so his estimates are conservative. I don't remember seeing anything about seasonal storage.

You may ask about colder regions. Seems like the solution there will be
1. Trash burning (getting common in Scandinavia.. you could even do it with CO2 capture as a power plant in Oslo, Norway is developing), with district heating
2. Geothermal for district heating
3. Nuclear for a bit of extra baseload (UK, Sweden and Finland are all building nuclear)

Also keep in mind that to go zero-carbon, we need to make a hell of a lot of hydrogen, ammonia, e-fuels, biofuel/oil/coal (I just read news about a Danish company starting commercial operation of a giant microwave reactor that can efficiently make bio-oil/coal from sewer sludge).

All these solutions will imply a lot of storage capacity. If you're making enormous quantities of hydrogen you're going to have buffers at both the production and consumption side. Production can probably be throttled if needed.

I'm guessing that the hydrogen power plants we already have will also be kept around to serve as backup. There's some pretty serious talk about switching the natural gas pipelines from Norway to Europe from gas to hydrogen. First making hydrogen with carbon capture and storage, then green hydrogen made with off-shore wind.

And off-shore wind is another thing that's getting more common. If you build really big off-shore wind turbines the production is very reliable.
> Right in the midst of that, the US elected the 45th and we all know how that one went.

If there’s one thing we’ve learned in the past 7 years (through Trump, Brexit and Covid) it’s that propaganda works.

See how you listed concrete issues for most of your complaints, but nothing specific for Trump? Just “we all know”. But if you actually think about his presidency, and ignore the fear mongering and propaganda, nothing bad actually happened! (Covid is, of course, another example, but whereas the virus itself wasn’t that bad, the governments’ reactions to it, was.)
Well given that humans actually exist as opposed to a fairy tale that does not, it’s a pretty easy swing as to who’s at fault here.
The path to migrate to Zig is, or would be, the most straightforward, except that that language is not ready. But in design terms it's definitely got the things the OP is championing C++ for, and a better story for actually addressing longstanding systems programming issues instead of heaping stuff onto the C toolchain and therefore making everyone debug C build-time errors.
Nice.

For years I've been using [direnv](https://direnv.net/) for this, setting environment variables which git picks up. This looks like a more feature complete equivalent, although to be honest I only really need switching of committer email and the SSH key used.

My service isn't very expensive (one of the lower ones in the industry).

The origins of these people are often problematic countries (places I couldn't accept a payment from even if I wanted to).

Some of these individuals (~30%?) seem to be coming from legit domains and verify their email but don't appear to be the target audience. They often try to pay without using the service. I believe these people have compromised mail servers and are trying to test stolen credit cards.

I'm not greedy.
Product Lessons from the Success of the Arc Browser
Is this a serious comment? Netflix does not and should not base its strategy on how you specifically choose to consume media. Surely you understand that most Netflix users don’t use IMDb/RT at all, let alone as a recommendation ‘engine’.

Netflix, especially Netflix back then, is highly reliant upon in-product recommendations because if people sought out specific pieces of media they’d often find that Netflix didn’t have it.
Read the article. They explain exactly how batteries can replace (yes, replace) the coal plant. In short: renewables have a hard time matching real-time demand. Clouds come. Wind dies down. What do you do? So in the past they needed that coal plant to add extra generating capacity, when needed. But now, with the batteries, the battery can store the surplus of renewables not instantly needed. Then when clouds come or wind dies done, the energy flow reverses and batteries deliver this surplus, hence smoothing supply.
This guy is in every single crypto thread here spouting anti crypto nonsense. Don't expect an actual in depth take.
There has never been a 3 week wind drought recorded on the North Sea. Wind droughts on cloudy days are even more rare.
I think there's a lot of institutional skepticism in general. Like the game is rigged, and alternative things are secretly nasty and fueled by ulterior motives. This is not surprising, perhaps it's even warranted.

What's really irks me is the other side of the coin, the things that get a "free pass," like (for instance) fossil fuels and their entire production chain. I see a lot of squabbles about the negatives of various energy tech, and somehow the order of magnitude difference between that and fossil fuels is brushed over, not to speak of oil companies' clear manipulation of public opinion.
Ostensibly it is just warm water from a cooling system. Like a PC watercooling system, except the reservoir is literally the Pacific Ocean.
So greed isn't always good.
I'm dismissive because I get tired of seeing shiny new projects that claim to solve issues when they don't seem to actually see what the problems are.

If the goal is to create opensource plans / design framework then doing that where the industry is (framing in the USA, maybe brick in the UK from other comments, etc.) is the way to benefit people, not trying to push them towards a unique "block" system that no builder has ever used.

If the goal is sustainability then a focus on locally sourced materials, energy efficiency, building longevity, or numerous other parameters would make sense. If I have a main criticism it's that their system seems to be based on the idea that using a block based design is a good starting point and not as a consequence of aiming to find a system that maximizes the aforementioned parameters.

Having worked in the industry I feel your pain and would agree that so much is broken. Here in the USA it is hard to find good contractors and harder to find ones familiar with building highly energy efficient buildings that normally require a very high level of attention to detail. Often the only projects I see that are highly energy efficient and/or green/sustainable are for very high end clients that are paying far more than a normal person could afford.

To offset that wall of negativity, if anyone wants to read about some (imo) good stuff check out the Pretty Good House (PGH) standard and Building Science Corporation (BSC).
On the other hand, other law enforcement agencies explicitly require that kind of data to be deleted, especially when the GDPR is concerned.
Easy, just move the power demand. Make it super cheap where it's naturally occurring, and a wizard, er, the market will solve it!
I will note that the ETFs are using Coinbase, Gemini, and Fidelity for custody. These companies have been providing Bitcoin custody for years without being hacked AFAIK.
I think they suck just like crypto, these are all mechanisms rigging the economy in favor of the already wealthy. If we don't unrig it we will eventually get civil war. Popular immiseration eventually leads to upheaval.

I have real doubts about this tech being viable on the market. For one thing there's a huge psychological barrier for many people, as anyone who has worked in nuclear power can tell you. There's also the issue that this relies on Nickel-63, and while unfortunately info on total demand/production is significantly paywalled, I don't think it's enough to support something like this. Outside of chromatography and explosives detection, there isn't a huge market for it, which implies low production.

It is also true that it isn't as dangerous as many other isotopes, but unless these batteries are sealed to last 100+ years, disposal/recycling is going to be an issue. That will add cost, even if the production of Nickel-63 can be scaled up from (probably) 10's of kg's to 1000's of kg's annually.
The Wirecutter model is to take what Consumer Reports reports used to do and eliminate all the hard parts like actually learning the science behind the product, performing serious long-term evaluations, and building funky stress testing machines. (And the big one, not accepting advertiser dollars.)

What's left? Some underqualified millenials doing a bunch of Googling, buying some products off Amazon, chatting about them on a Slack thread, and then summarizing all the anecdata using no fewer than 10000 referral-generating words.

Suffice it to say I find their recommendations basically useless. And in several cases aggressively wrong, like they recommend a product I know from personal experience to be among the worst in its category.
Children now 'biggest perpetrators of sexual abuse against children'
I feel like I'm the only person who hates Spotify, Youtube Music, Apple Music, etc... None of them give me music I want. I pick some old 60s vocal jazz and within 40 songs all of them try to stick some pop music into my "radio".

Other issues are picking some artist, clicking "radio" and getting the same playlist every single time, maybe shuffled. The same 10-30 songs. No variety.

Other issues are not understanding what I want. Say I listen to an 80s synth band. Pick "radio" and I'll get effectively "hits of the 80s" instead of "synth bands"

Similarly say I want female vocals, no way to filter on that.

This is one think I liked about the original streaming service, rhapsody. Each artist listed influencers and followers. That was a way more accurate way to find similar music than AI which AFAICT at best sorts by "most users that liked X also listen to Y"

It's enough to keep a low power microcontroller and maybe a low power sensor or two alive. You can get chips and sensors that will work with that budget, you just have to be very conservative and sleep aggressively. E.g. there are PIC chips that consume 25 uA/MHz at a couple volts while active (not sleep) and can do useful tasks: https://www.microchip.com/en-us/solutions/low-power
Crypto is one of many. Just like SPACs, crowdfunding and the entire VC landscape are always finding millions of ways to dump on retail after they made their 100x on unprofitable startups (90% of them have failed) founded by their friends racing to the IPO finishing line.

This is why they have to continuously raise money and breathlessly celebrate it on social media and even on this site as if "raising capital" into the Series H is a good thing.

Sorry to disappoint you but it isn't going to stop.

We're pretty worried about trying to monorepoize our existing code bases together.

How do we not break all the merge commits that link a project specific PR? Complex filter-branch I guess. How do we make GitHub able to actually help us navigate the past effectively?

It seems like we need some custom tooling to help us replay the past step by step across multiple repos, doing some rewriting as we go.

And what if it's not just your own repos one is managing? What if you also are trying to manage external deps too?

I see much validity to wanting good git-of-gits. Also if anyone has any suggestions for stitching together monorepos out of existing repos, please please comment!
It's really unsettling that I routinely find out that major services I rely on are down from Hacker News. And the frequency with which these outages happen. Yesterday was Github.
Mentally, I use handpicked spotify playlists as if it were an "indie" radio : They are curated (no Spotify algorithms), simple to "activate" (just play), and many are frequently updated.

One advantage is that I can easily "tag" certain music, to explore in depth, but also to find new playlists so that the cycle continues and the music never stops (like a radio).

Speaking of prog, I'm currently enjoying this 80+ hours playlist :) [1].

The project's also been running for so long that its hardware requirements have slid from "yes, you can install and boot Hurd on your computer" to "well, okay, maybe if you have an older PC" to "we recommend running Hurd in a VM".

(To back this up: Hurd currently only supports the 32-bit x86 architecture, can only use a single CPU core, and is limited to 1 GB or so of RAM. It also lacks support for USB, PCIe, or anything dependent on them.)
They wanted to make a point about the usages on that page, I simply provided more usages from the page that run counter to their argument. I’m not arguing the merits of the usages on the page in general; I think it’s not very relevant.

The strongest point that I think could relate is that you can’t download an app from the Mac app store onto an iPhone to run.

In this light, it’s like a corporation owning separate fruit stand, bakery and butcher shops.
Other signs for me personally:

* Sales schedules dictate product development timelines rather than the other way around

* Leadership thinks about practical operational/logistics issues only when forced to

* The importance of "culture" is brought up without fail when talking about working from the office, and never at other times

* Leadership is fond of setting goals and deathly allergic to providing incentives
Of course they are. Anyone who's seen that documentary about Israel meddling in UK politics know that these people have a lot of power that isn't just military.
Not sure I'd call that an inflation rate as it doesn't factor in any baskets of goods and services.
Correct. I did exactly that for my friend.
It’s also the only way for most to get crypto exposure in an IRA. Avoiding the insanity that is crypto tax filings may be worth the risks and fees.

Would they use GPT-4 to detect if some "personal" GPT is malicious in some way? Like injecting spam URLs to the answers, send private information somewhere else or something like that. Prompt injection is the kind of malware for such market.

I suppose that up/downvoting a bot to give it more "score" somewhat would be based on people voting individual answers inside that GPT.

I agree with this other than the part where you say vegans have to bend over backwards to meet their dietary needs. It’s really not hard to eat a vegan diet in 2024. The hardest part is running into other people who presume you’re judging them when you order your vegan cheese or whatnot, and that’s really not that hard either.

Always have an engaging side project or non-work interest (a family even!). A slow-growth company is torture if you have to give it 100% of your attention. But in some cases you can turn corporate disfunction into a means to fund your own interests.
Can you clarify your usage of "thermal" here? Most everything except photovoltaic is thermal.

In the US, we usually name the heat source -- coal, natural gas, nuclear -- even though these are all thermal in operation. And the word 'thermal' does not show up in any of those when we talk about them.

The only time the word 'thermal' shows up in US usage is with the 'geo' prefix, and I can't imagine compressing the runtime of a geothermal plant, it's the perfect base-load plant. Are we talking about different things?
Thanks! No need to apologise, it's fun to run the numbers.

On top of maintenance costs we probably need to account for finance costs (5% interest rate means repayments of 100mil over 10 years) and the fact batteries don't tend to ever get charged/discharged 100%.

Presumably if you built this you'd want a bit of return on your investment, so you'd have to charge more on top.

TBC: I think these batteries make economic sense (even more so if coal/petrol had externalities baked into their costs), but we don't want to oversell things
Coal, oil, or fossil gas are traditionally considered thermal generators. Burn, make water hot, make water do work.

I wonder how prohibitively expensive (or not) this will be. The other comments talking about lack of applications they're able to think of on the spot are rather besides the point, the only questions are whether this will be produced at scale and at what cost.
