scoopertrooper··on Solar canopies on parking lots
As in the picture accompanying the article, the solar shades don't need to cover the entire area. You can leave open sky over corridors to allow trucks through.
scoopertrooper··on How Did Elevators Lose Their Music?
Quite possibly the reason. Though, I think retail, in general, has become quieter, outside of supermarkets (for some reason).

In some ways, it feels like as visual aesthetics went minimalist, so did the soundscape.

I'd personally like to hear an even quieter soundscape. It's so annoying to be sitting in a bar or hotel with sound blasting at you. It's like they expect people fear being alone with their thoughts or to be unable to make conversation when together, so they feel the need to fill the void.

scoopertrooper··on Amazon to acquire maker of Roomba vacuum for roughly $1.7B
They're getting eaten alive by competition though. Their first mover advantage has largely dissipated.

Amazon might be able to give them exactly the kind of capital injection they need to get back in front. Alternatively, they might end up just becoming a brand sitting on top of an OEM.

Time will tell!

scoopertrooper··on MIT invents $4 solar desalination device
That's where the $4 come from.
scoopertrooper··on US regulators will certify first small nuclear reactor design
In fairness solar efficiency was below 10% in the 1970s, while the world was already producing many gigawatts of nuclear energy at that time.

It's not as though Germany could have 'decided' in the 1970s to have 2022 technology. Sure, increased investment at the time may have sped up the development of renewables, but it still wouldn't be fast. Science doesn't quite work that way.

scoopertrooper··on Build Unix, Not Uber
It's an interesting question. It'd certainly be an odd cooperative.

Most cooperatives have a large number of members with roughly equal economic power. So, ideas like one-member-one-vote and equal income distribution make sense.

However, in the case of companies requiring FOSS services, I imagine the most valuable customers would be large corporations working in highly risk averse industries like telecommunications and banking that feel the 'need' for a support contract to go along with their linux distribution.

But there would likely be a mix of large blue-chip companies, smaller service suppliers to the aforementioned companies, and other companies that want to leverage services beyond consulting like Red Hat's managed OpenShift offerings.

So our FOSS cooperative membership distribution would probably be heavily weighted towards smaller companies, but most of the revenue would come from the long tail.

I don't see how the small cadre contributing the majority of the revenue would be satisfied having effectively zero voting power. So you might have to mix up the model a bit to assign voting power on the basis of revenue contributed or some proxy like the number of contracts signed.

scoopertrooper··on Air Support in a Backpack: The Switchblade
There are of course degrees of failure. Egypt suffered a strategic collapse.

Russia failed to achieve its primary strategic goals. It has even failed its secondary strategic goals like taking the Donbas.

Instead of a swift conquest of Ukraine, they’re stuck in essentially a stalemate in most of the regions they control. They’re also facing an imminent counter offensive in the south with Kherson (their primary prize claimed so far) increasing cut from the lines of communication.

Meanwhile, years of economic growth have been erased from the Russian economy, it’s diplomatically isolated, militarily discredited, and facing a reinvigorated and enlarged NATO.

I’d call that a strategic failure.

Their goal was to take 100% in a few days though. So 20% doesn't sound like winning to me.

They've already failed strategically, so they're desperately trying to gain territory in areas where they have a localised tactical advantage (places near the border).

scoopertrooper··on New embedded programming language with C as a host language
Could this not be said about any stylistic choice though? Why should websites pick their own heading weight? What's wrong with the default text colour? Who are you to tell the browser not to use the default padding?

People have been mucking about with typography since Gutenberg's day and they're not going to stop now.

I'm personally 'font blind', but I don't have a problem with people being creative and making aesthetic choices.

scoopertrooper··on Detroit’s new personalized flight information board is straight out of sci-fi
It'd be great for trains in countries where they only announce the platform shortly before boarding.

It's such a hassle to find the departure on a giant board and monitor it closely among a sea of boarding times.

This is especially bad when you're running late and suddenly you have to stop your frantic race to the gate to methodically peruse the board.

scoopertrooper··on Nobody likes self-checkout. Here’s why it’s everywhere
Am I the only person that likes self-checkout?

I remember the period before self-checkout: interminable queues, being stuck behind an old lady making small talk with the cashier, and receipts with double-counted items.

scoopertrooper··on Ask HN: macOS – is there a multiple “workspace” solution?
I just went out and implemented this for you as a basic feature of the operating system.

scoopertrooper··on Crypto-assets and decentralized finance through a financial stability lens
Quite a few allegations there. It seems like the simplest way to settle this discussion would be to point out a few practical applications of crypto that provide real utility to the finance system.
scoopertrooper··on Crypto-assets and decentralized finance through a financial stability lens
Crypto may, one day, find utility as part of the financial system (outside of drug deals, sanctions evasion, money laundering, tax minimisation, greater-fool scams, and Ponzi schemes), but its recent volatility has been in no way related to that.
scoopertrooper··on System76 Lemur Pro Linux laptop with 14 hours of battery life
Yeah, I think the M1 MacStudio was just establishing the form factor in anticipation of M2. Apparently, that requires a better thermal solution as the M2 MacBook Pro throttles much quicker than the previous generation.

A moderate breeze came along and the Twitter board gave up on it after about an hour.
scoopertrooper··on Bonsai Browser is now open source
Presumably, but it seems most of the work in to improving the productivity of certain web browsing workflows.

It may help improve some tasks, but not exactly core product stuff.

If my capital were on the line, I’d be pretty annoyed seeing it spent that way.

Trying to workout how this relates to the core product of this startup (3D game UX analytics).
scoopertrooper··on Why I’m Cryptophobic
> Is the Mona Lisa not valuable?

That's such a silly argument. There are thousands of paintings around the world with the same level of scarcity as the Mona Lisa, but have far less value.

Scarcity drives up prices on items that already have some perceived value. It doesn't create any value itself.

scoopertrooper··on FTC Sues Walmart for Facilitating Money Transfer Fraud
They should just get rid of gift cards all together.

I couldn't think of a worse gift than a gift card. It has same level of thoughtlessness as gifting someone a bunch of cash, but brings them less utility because they're constrained to spending it at a specific store unless they on-sell the card at a haircut from the face value.

scoopertrooper··on Fresh is a new full stack web framework for Deno
Doesn't really matter if the relationship isn't linear like that. I suspect it's more likely conversions start to drop off after certain thresholds are met e.g. 3 seconds causes conversions to drop by 5%, 20 seconds causes them to drop by 30%.

Just averaging out those numbers could result in engineering time being wasted chasing rapidly diminishing returns, if the site is already below one of those thresholds.

scoopertrooper··on Bitcoin mining becomes unprofitable as BTC price falls to average cost of mining
Doesn't really matter. If the price of Bitcoin is below the cost of electricity and labor required to mine it, then it's irrelevant that the card won't be as productive (lose money at a greater rate) in future. You're still losing money either way.

The only valid reason to continue mining would be that you expected that the price of Bitcoin would exceed the mining costs in the future. Then you would stockpile them and take advantage of the reduced hashrate as other market participants exited.

scoopertrooper··on Bitcoin Falls Below $20k for the First Time Since 2020
Even if you bought your rig on credit, you're still on the hook for making those payments regardless whether you have the machine off or on, so the cost of the machine is still a sunk cost.

Therefore, it'd make more sense to keep it running for so long as the machine hadn't been repossessed and the profits from mining outweigh variable costs such as electricity.

Repossession and liquidation can be a slow and costly process and the initial cost of the machine is also a sunk cost from the perspective of the lender and a mass wave of defaults could put their liquidity at risk. So, they have an incentive to make accommodations to the borrowers in order to ensure at least some payments keep flowing.

scoopertrooper··on Bitcoin Falls Below $20k for the First Time Since 2020
Exactly. I was speculating on why the hash rate doesn't seem correlated with the price of Bitcoin.

The miners already have their rigs, so the initial investment wouldn't be relevant to the decision to keep mining or not. Though, you might expect the hash rate to decay over time as miners stop buying new machines.

scoopertrooper··on Realistic one-shot mesh-based head avatars
I think this could be used as a great basis for next generation video conferencing. Rather than compressing raster images of people speaking, we could send a model as an initial payload and subsequent instructions on how to manipulate it as the conversation progresses.

Most current networks can handle video conferencing (relatively) well. However, if 8k video or something like Light Field displays ever catch on, then we might end up needing orders of magnitude more bandwidth to drive video conferencing, so this might be an enabling technology.
