ok_computer··on The spotted lanternfly is now in Illinois
In eastern PA:

* <= 2019 : awareness but didn’t see many

* 2020 : population explosion

* 2021 : not as many

* 2022 : bounces back, these might be a problem. I bought green tape in 2021 but never wrapped my trees

* 2023 : rare sightings

There is a penn state study saying the fly may not be as damaging as expected.

Maybe birds are eating them or they kill all the bad trees. Life finds a way.

ok_computer··on MP3 vs. AAC vs. FLAC vs. CD (2008)
Also, I’ll note that I think the amp and speakers are far more contributing than the master file format. And the quality of the master and mix and tracking even moreso.

I’ll run youtube rips of dj sets through some light hardware compressors and preamps and it sounds great. You cannot have specs determine quality.

ok_computer··on MP3 vs. AAC vs. FLAC vs. CD (2008)
24 fixed bit and 32 variable/ floating bit rate masters have more head room that may avoid clipping but doesn’t guarantee that. 48 or 96 kHz is useful for time stretching and maintaining fidelity (maybe other post processing without aliasing).

That is all intermediate formats and doesn’t really say anything about what is best for consumers like the standard mastered cd quality at 16 bit 44.1 khz.

Bandcamp is a cool market because I can download wavs from albums to store on my phone. You can see what people use as masters and its all over the place. There are many 96khz masters around and 24 bit depth is popular.

I have a usb audio IO that supports 192KHz across 8xin+out. Those file’s just clog up hard drives so I figure 96 is good enough for bat music.

ok_computer··on Tire dust makes up the majority of ocean microplastics
Honest question how does shear force proportional to torque not factor in? Coefficient of friction is shear over normal. Mechanical properties are a function of temperature and quick startups assuredly contribute to wear. An extreme example is drag racing. Cars are highway driving in steady state cruising for more miles and time but in the US around town driving has stop lights.
ok_computer··on Most demographers now predict that human population will plateau
That Manhattan remark was extraneous. I wanted to note that decreased population does not always lead to decline in property value. There is a shift from a more widely distributed desirable city middle class to concentrating wealth in coastal cities or new western development.
ok_computer··on Most demographers now predict that human population will plateau
I wonder if in-country population redistribution would counteract any alleviation of realestate prices.

The US has many landlocked, east coast, and great lakes city outflows where you can buy property inexpensively. But people tend to not want to raise families or retire needing medical care in declining areas given the choice to leave.

New York city Manhattan has 600k fewer people than 100 years ago and property price to average salary keeps climbing.

I don’t know what the magic is that to expand property ownership. You see cities with thousands of blighted homes and new build suburbs developing 30-90 min away at prices that are a stretch for even well paid middle class jobs.

I think affordable home building and financing could happen somehow but the trend is not going in that direction.

ok_computer··on DAWproject: Open exchange format for DAWs
This is a hilarious take and juxtaposition with MP3 (lame encoders anyone?) and some far fetched gtp application. It would be a musak equivalent of the bored ape nft’s.

Like midi note transcription or waveform modeling will be cool machine learning tools. An end to end composition and mastering bot may make something passable like other current derivative music out there, being generous by saying passable.

Show me the leaps and bounds in self-driving cars that were only 3-5 years away 8 years ago.

There is still need for better daw, music transcription, and audio file formats in the next century. Lol humans want to make art in their free time not play around with pretend chatbot personalities.

P.s. people still record to TAPE and it sounds awesome even though there are albleton plugins

ok_computer··on Ask HN: Any hardware startups here?
Just a note that the infant ones have a 5-year lifespan from date of manufacture. Not sure if it’s the nylon straps or the foam mechanical characteristics.

We were gifted a hand me down and I had to cut the straps and bag it.

We ended up handing down the two infant sized ones we got that were the same model.

Also any car seat involved in a collision needs to be disposed of.

I dislike waste but you don’t mess with car seats and helmets.

ok_computer··on Plastics are poisoning us
I thought bio / water degradation of PLA was seen as a feature.

PLA and other acid co polymers are used in resorbable stitches and polymer medical devices where the biproducts are organic acids and carbon dioxide.

I second the ‘I don’t know’ for actual health effects of PLA but wanted to provide a counter point to comparing PTFE (indestructible C-F bond) to PLA (readily hydrolized C(=O)O- bonds)

ok_computer··on Ignoring boys' emotional needs fuels public health risks
I’m on board with tailoring upbringing to the kid’s gender and being conscious of how society sometimes treats young men in a negative way.

But I second that is a weird take or point to throw in.

ok_computer··on Swing VPN app is a DDoS botnet
Hi, I was mistaken. I think i confused a separate security compromised server incident and this walking back law enforcement cooperation

https://www.pcmag.com/news/nordvpn-actually-we-do-comply-wit...

They don’t keep traffic logs

ok_computer··on Swing VPN app is a DDoS botnet
Same, I made the poor judgement of subscription to Nord vpn years ago that I ended up not really using because many streaming sites blocked the vpn ips. Then I hear of the behavior of the company claiming they don’t take logs but they definitely take browsing logs. I felt like I was duped into a 2 or 3 year subscription upfront and didn’t really understand the product space or how to evaluate the different companies. Like are there any objective news sources to rank these services and what internet comments to trust at face value? I listened to a youtube ad in the first place, so I’m unsure what I was expecting.

Mozilla gained good will over the years and I like the browser. The vpn is fairly seamless and permissive for number of devices. I understand it is a wrapper on Mullvad and we are paying a healthy overhead. Still, it is worth it because I’d trust that if the vpn service provider behaves in bad faith that Mozilla will be able to quickly respond and adopt another provider. Whereas if it were up to me I may hear of it years later and not necessarily know what service to adopt instead.

My use is merely hoping to reduce tracking based on ip. I wouldn’t trust it to be subpoena proof. I’m not into pirating music anyway.

They listed prozac that is fluorinated

But I’m unsure the line where perfluoralkylated is reached. I’d think if the compound had alkylated chains instead of a fluorine-linked head group.

ok_computer··on Historical code from reddit.com
Old reddit + darkreader +ublock origin extension on Firefox is my preference.

I’d like to know others’ opinions on darkreader: is it a great security threat. I perused the information it discloses it gets access to but have not seen many online criticisms.

ok_computer··on Amazon Backs Out of Climate Pledge, Deletes Shipment Zero Initiative Blogpost
I'm against the hype that every storm is "omg gobal warming", getting a stream of existential dread in news headlines and personal discussions or posts is tiring.

That said, the globe will be easier to live on if the +x degrees C is minimized from pre-industrial temperatures. Like I'm sure humans will make it but it's up to us the quality of that existence and if we'll share it with current species.

I also get that the globe goes through cycles and the suns heating up in solar cycles, etc. Still pushing more ocean water into the atmosphere, sinking thermal energy into the oceans where we are using up the latent energy of ice melt, (after which there is less cooling capacity available in liquid water than surface ice at constant temperature), acid-ification of oceans that provide food for much of the globe, accelerating arid-ification of already progressing geological areas like US southwest or sub-Saharan Africa, all of these could in part be natural progressions. But if its in our control to reduce the greenhouse gas concentration (that has mechanistic explanation for heat capture, it is not blind correlation) in air or do something crazy like atmospheric geoengineering more people and plants and animals would face a better shot.

Global average temperatures are one part of the story. There is high-frequency temporal variance and spatial variance. Its possible to make a rough order-of-magnitude approximation for energy released in a hurricane. Higher incidence of high wind and heavy rain hurricanes is a measured (~100 years) value. We won't get rid of storms or famine & flood magically. But maybe transitioning from burning stuff for all energy and adopting more scalable living models wrt density and transportation could slow down the bad effects. Its not a conspiracy. Plenty of companies want to capitalize on teh movement but that doesn't invalidate the underlying motivation to change from the current state.

ok_computer··on 50 years in filesystems: towards 2004 – LFS
Those are all good points. I will read the rest of the links!

My question is can those uncertainties be fixed with a less performant, ordered, and safe file system for typical application use. Then bleeding-edge with plenty of sharp edge cases for high performance compute work that application programmers can handle at app level? Because it is nuts how fast hardware and inexpensive RAM are and I think if you add +30% time on file write IO that will not greatly impact the user experience vs all the other causes of lag that burden us like network and bloat.

Then in the HPC word if a new byte cloud where all context is in some database with a magic index naturally comes to be we can move to that. I won't rule out needing to change the underlying file system because that's pretty over my head and there are good ideas I don't understand.

My point is to push against the proprietary format vendor lock-in file system abstractions like I get in nested objects in microsoft powerpoint or word or apple garage band where the app is merely wrapping files and hiding your actual data that you can pick up and move to another app. I don't want to need to adopt a way of thinking about pretty simple objects to use every different program.

I like wavs > flac, plain text > binary, constant bit rate > variable bit rate, sqlite > cloud company db (not really fair but just saying sqlite one-file db is amazing). Storage is inexpensive and adding in layers to decode the data runs a risk of breaking it and I like interoperability. Once you lose the file data and just have content clouds there might be compression running on the data changing the quality, e.g. youtube as a video store with successive compression algorithms aging old videos.

It drives me nuts when needing to attach things I'm faced with a huge context list where I'd rather go find a directory. Abstractions are just that, mental models to avoid the low level stuff. I'm still cool thinking of my information as file trees I think that's an OK level. But you're right complex operations with a file system has issues. I've messed up logging and file IO not thinking it through and it made me think about needing to fix my mistaken code.

ok_computer··on Programming with natural language is going to work (2010)
I was going to say the same thing, we’ll all be YELLING OUT SQL to our mic terminals and syntactically backtracking from the expressiveness and imprecision of our dynamic typed languages of choice.
ok_computer··on 50 years in filesystems: towards 2004 – LFS
I think the simplicity and flexibility and lack of overall framework is the benefit. Dead simple bytes that may or may not be arranged in a way that works with the program you’re trying to open them with. Then build the relational model on top of it.

Git’s now out of style and we’re onto ____ but my storage is identical. I used to use flickr but now I dump directly to s3 and my jpgs are indistinguishable.

Especially so some consortium of tech companies don’t come up with the next-gen db/fs with bolt on features that no one’s asking for and telemetry to improve your file recall experience. Or logging into my fs because I need customization. For instance any modern web app is built with overkill tech that adds complexity because in certain scale uses that is necessary.

Give me trees of utf-8 encoded flat files any day. Not nested object relational models of stuff that ages faster than milk.

ok_computer··on JPL Horizons Sending Too Many Emails
Agreed. Once you start post-send changes for remote deletion then there could be further modifications to the spec by less than benevolent marketing tech companies for dynamic email. A/b testing facts. Workshopping layouts or grammar sentiment to see if you’ll click a link. Like some dumb video streaming homepage.

Keep email the same a printing to paper. One improvement would be encryption over wire but what can you do.

ok_computer··on Joint statement by the Department of the Treasury, Federal Reserve, and FDIC
> expecting that Federal regulators were doing their job

Regulators set a framework that an industry should follow. It is incumbent on industry players to act in good faith and not operate on edge case regulatory compliance. It is not on the regulators that an agent lobbying against the very regulations for stress testing their balance sheet then turns around and does something dumb. Analogously the USDA and FDA aren't not doing their job if a food or pharma manufacturer intentionally labels dog food for human consumption and ships it.

This type of accounting is criminal and needs investigation. So what if your cash isn't performing to make target yields. Its on you to responsibly manage it if that is your stated mandate. And fed rates didn't balloon overnight. J Powell forecasts weeks in advance.

This is not on the regulators. The bank should have operated with a better risk profile. And all these disruptive companies need better financial sense than to be storing their >250K assets in a savings and checking account. I don't know what that answer is I haven't had the privilege.

So what if Stripe recommends this bank to all their clients. Seems like their incentives need investigated. What did they have to gain by funneling a clientele to their bank.

This isn't on the Fed or Treasury or SEC. Though their response may create future problems arising from this assurance.

ok_computer··on Joint statement by the Department of the Treasury, Federal Reserve, and FDIC
The bonds are good to yield on the stated timeframe. You need to hold them to maturity. They bought long term bonds and tried to sell them after newer higher yielding bonds came out. Bad decision. Also lobbying to avoid stress testing below 250B instead of 50B.

They could have kept deposits as cash and watched the value erode like a dumb retail consumer has an option to do. But that’d look bad for bank investors.

So now the Fed and Treasury are responsible for negative yield on bad bets if that account crosses 100B. Cool. I only have about 100B to go before the US government cares about my negative position. 401K takes an L because interest rate rises and the SP500 being a stock buyback circus. That’s on me I guess.

Anyone saying well it’s not using taxpayer dollars. Whatever, it is using our feds time. This whole thing is now J Powell and Yellen focusing on a cottage industry serving billionaire interests instead of using their time and agency to work for that dumb aforementioned retail consumer undergoing inflation and a pending recession.

In an agency where any intervention sets a precedent this is now telling regional banks to go ahead and yolo your balance sheet. We got you.

I want the startups to get their money through liquidation of the bank at whatever discount that comes to. 80c on the dollar, whatever it isn’t your money anyway it’s VC money. All savings accounts come with 250k FDIC insured. So play by those rules.

ok_computer··on What does Silicon Valley Bank’s collapse mean for the financial system?
jfc, goldcoin has been a thing for 13 years

[goldcoin 2010](https://goldcoin.com/about-us)

^^^ this is a terrible idea. if you're going to buy gold don't do it thru immutable public ledger contracts. If you cannot front the cost of one purchase unit then don't buy any. Fractioning the $USD/g cost of a commodity metal is not innovative.

ok_computer··on What does Silicon Valley Bank’s collapse mean for the financial system?
A point to emphasize on my other comment:

Valuation is not remotely related to GDP until there is an IPO.

Startup valuation on pre-profit businesses is dominated by the greater credit and bonds performance. Hopefully the impact radius of the inflated valuation coming back down to realistic levels is contained to private capital and not the whole country’s 401Ks.

ok_computer··on What does Silicon Valley Bank’s collapse mean for the financial system?
I’m not trying to disparage or minimize startups. Merely pointing out that this bank’s business model does not represent the greater economy. I’m not putting down the banks customers saying that they are cash intensive risky businesses. That is the nature of a startup.

Also, 1B valuation in an asset bubble doesn’t really mean much with rosy assumptions on price to earnings ratios that is unproven. Unless that 1B company translates to public through an IPO that 1B valuation can be 10000B it really doesn’t yield any concrete value. Pre-market due diligence is a dark art and venture capital is operating on perverse incentives to value things. If you take out a large loan on your holdings in a 1B private asset light intellectual property light cash burning business then that person issuing the loan is irresponsible. Same thing with housing inflation, pointing to comps and estimated growth since that sale leads to inflated valuations. Except there aren’t many comps in a startup space and banks and credit unions are smarter at not giving out more money than they can collect back through a sale in the range of 300k-1M.

Sounds like there was too much deposits and the demand for returns made the bank choose a time risky purchase if interest rates rise. Then they did over a year. Then cash hungry customers made a run after rumors.

What does that mean for JPM and Wells Fargo and Blue Cross and Humana and GMC and Maersk? Not much because (I really hope) they’re not hedging their accounting in shares of a high risk VC regional bank.

Businesses need to adapt to higher interest rates and that alone is going to take the wind out of the sales of some speculative business models. The bank was underperforming on returns from their accounts so they chose an irresponsible bet.

In the US we need to collectively get of the cheap debt sugar rush and check the assumptions in what is viable growth and valuation. But that doesn’t mean the sky is falling because an AI healthcare startup cannot raise their next funding round.

The major banks should be good because they’re stress testing. The cheap money and every new company getting the cash to scale as has been the case for 10-15 years is likely behind us.
