> I'd rather pay for contact lenses forever, put them in, and take them out every day than risk anything to my vision

Same same same. Soft contacts are pretty freaking great in the grand scheme of things -- go read contemporary accounts of what it was like to suffer from severe myopia even just 50 years ago. The hype surrounding LASIK when there is a cheaper, non-invasive, lower risk, minimally inconvenient and widely available alternative never made an ounce of sense to me.

I am seeking a hands-on, team-oriented role at a stable, technologically innovative company where we will be able to facilitate evolutionary and revolutionary adoption of various technologies, intended to produce consistently growing operational return on investment.

I am passionate about improving operational processes and flows via the collaborative approach of design and architecture. Fundamentally, I am a programmer with decades of hands-on operational experience, ranging from all kinds of Linux system administration to databases to strong networking skills. Collaboratively designing and shipping high availability is my forte. Through many and diverse focus areas, LiveOps achieved 99.99% availability in Q4 2011. Above all, I seek to understand, assimilate and process all of the issues, big and small, that stand in the way of efficient and smooth operations, using that analysis to design elegant integration solutions. Shipping that automation so my co-workers can get their work done is job one.

Payment systems turn out to be particularly thorny because they hit an intersection of technical issues with conflicting goals:

* You want them to be as fast as possible (ideally: instantaneous)

* You want them to be validated (long-poll to a third party validation service)

* You need them to be sequentially auditable (this is a "... or you could go to jail" requirement)

* If a failure occurs, you don't want to be out your own money

While these are solvable, it's the reason that so many cloud services suddenly hit scaling issues at the payments layer: things are going great and then that layer gets involved and "oops, hold on, we're waiting on Visa's servers. Still waiting. Stillllll waiiiiiting..........." Or the team was certain they'd simultaneously solved speed and sequential auditability this time but, oops, there's yet another sequencing point that's actually a bottleneck.

Risks for both contact lenses and LASIK are incredibly low, but with that said strictly from a quantitative perspective, contact lenses carry a higher risk of permanent vision loss than LASIK. The issue is that the risk of LASIK is almost entirely front-loaded whereas the risk from contact lenses causing an infection that results in significant to total loss of vision accumulates little by little.

Everything about crypto finance coin world is irony IMO.

The magical freedom / ideology implied by the bitcoin whitepaper is contrasted with the fact that now we're "free" to get scammed by those in power again, potentially far more, and with even more impunity than ever before.

It's all a speed run to slowly realize that the terrible system we had, in fact had some good ideas / rules of the road that even empowered the little guy to some extent.

If you can't do anything with your self awareness it's equivalent to not having it.

What's the distinction between knowing I exist, but all my actions are pre-programmed vs not knowing I exist? You're essentially describing a detached observer, who watches their own body do stuff without influencing it.

The whole point of being conscious is being aware of yourself, and then using that awareness to direct your actions.

I had no idea people even had another definition, I can't figure out how else you could even define it.

You’re hung up on semantics. In practice, ISOs/TSOs report batteries in the generation mix because when they discharge, they inject MW just like any other generator. Interconnectors are treated the same way — not because they “generate,” but because they’re modeled as supply.

If you don’t like the terminology, take it up with the grid operators. That’s how the industry classifies it, whether you agree with the wording or not.

Again, I have no idea what you are trying to argue. We all understand how batteries work, yes they are not magic. From a fuel mix perspective or “generation” perspective they are lumped together. Most folks who are looking at this data recognize batteries are not magic, not sure why you are hung up on this.

These larger power-generation systems tend to be more efficient than smaller power-generation systems, not less, which should result in a cost decrease, not an increase.

Tennessee (for example) has fairly cheap electricity because the TVA uses a lot of hydroelectric, and since we have a ridiculous amount of rain and violent thunderstorms each year, every decade or two they build another hydroelectric dam and create a new lake, which generates more hydroelectric power (and a moderate increase in tourism/recreation). We don't have buried power lines (excepting in a very few places) but we've got a ton of redundant power substations and multiple transmission paths (because storms). The TVA and Corps of Engineers are kinda hardcore here otherwise the valley would flood about a quarter of the year and be sitting around in the dark for another quarter of the year.

Maintenance of the power transmission lines is paid for by the electrical customer as a part of paying for the electricity itself. This actually scales just fine. If your local electrical utility is not doing it this way, someone needs to explain to them how proper accounting works.

Calling a "hidden cost" is just a convenient way to say "We're making this up because we feel like it's right and we don't intend to show any proof."

If this intrigues you, and you are in the Bay Area, I would recommend checking out Audium.

https://www.audium.org/

Similarly, it places you in a room, turns off the lights, and you listen to an audio performance. Though it is more soundscapes interlaced musically than the Pitch Black Playback's focus on albums.

Given that the heart is generator which drives electrovolt oscillations through the nervous system and the fat of the brain, and that the extracerebral field created by the electrovolt potentials in the tissues of the brain is nonlinearly related to the electrical activations through the axons and dendrites in the tissues of the brain,

Are there electrical cycles in the brain (and thus feedback and probably spiking) or does the charge distribute through the brain in a DAG directed acyclic graph?

Are there stable neural correlates to ear worm or rumination or flow states, for example?

Is sustained charge necessary for data persistence in the brain, as it is for RAM?

Bitcoin is _not_ magically produced by the sun striking the ground.

There are mild returns to scale in running large-scale mining operations and as a result mining power seems to actually be somewhat centralized under the control of a small number of players: https://digiconomist.net/cryptocurrency-decentralization/

Not to mention that "decentralization" is a technical property and not necessarily desirable in itself. Users might care about fairness, avoiding sanctions, purchasing illegal goods, etc, but these are only weakly connected to technical decentralization.

I would think of it that way:

- no company generates revenue in its first second. Even if you start a lemonade stand tomorrow, you'll have to buy some lemons first. The time-to-revenue might be very short, but it's never zero. Therefore, making no revenue for 1 day or for 10 years is not a step change, but simply a point on a curve.

- Capitalism is basically a long history of creating vehicles with increasing sophistication to bridge that gap: provide funding for ventures that have returns in the future. This is intrinsically difficult, and it's easy to waste money, but it can work immensely. This started with the Dutch inventing limited liability corporations to fund ship expeditions, and today's VC is essentially an extension of that.

- It has worked well in the past to bet on companies that don't optimize for time-to-revenue, but something else – famous examples being e.g. Amazon, Google, Meta, who all lost lots of money initially.

Hence there can be companies that make no money for quite a while. And it can even turn out that the vast majority of the companies that make no money for a while never make any money. Accepting this risk is a feature, not a bug.

Part of the reason why it was on 24 hours a day for 20 years is that something got fucked up with the copyright and TV channels were using it as free filler.

When I was very young it merely competed with Miracle on 34th Street. And then it was just fucking everywhere. I’m not sure I’m entirely over hating it for never being off the air. Even though it’s been 15-20 years since they stopped playing it every hour of the day.

To me the simplest place to start is Fourier Optics. A carefully set up collection of lenses, illuminators, samples, and cameras can compute (well, physically evaluate) the fourier transorm of a 2D image. https://en.wikipedia.org/wiki/Fourier_optics (so you can for example do convolutions)

From what I can see in this area, the physical set up mainly computes forward passes by passing light through the SLM, while the computer computes the backward pass (using a mathematical equation that approximates the forward optics and computes its derivative). The nice thing is that SLMs are simply programmed to have a specific intensity pattern, it doesn't need a whole manufacturing pass to update the SLM.

That development time window, and the fanbase salivating for a sequel, makes me smile.

Nintendo famously spends something like 6-8 years on its flagship titles (both Tears of the Kingdom and Mario Kart World are in that timeframe). Sometimes, depending on the team you're working with and the material you have, it turns out the secret to making a good game is... Time.

802.11bf is working on sensing applications:

> With recent advancements, the wireless local area network (WLAN) or wireless fidelity (Wi-Fi) technology has been successfully utilized to realize sensing functionalities such as detection, localization, and recognition. However, the WLANs standards are developed mainly for the purpose of communication, and thus may not be able to meet the stringent requirements for emerging sensing applications. To resolve this issue, a new Task Group (TG), namely IEEE 802.11bf, has been established by the IEEE 802.11 working group, with the objective of creating a new amendment to the WLAN standard to meet advanced sensing requirements while minimizing the effect on communications. […]

* https://ieeexplore.ieee.org/document/10547188

> In recent years, Wi-Fi has been shown to be a viable technology to enable a wide range of sensing applications, and Wi-Fi sensing has become an active area of research and development. Due to the significant and growing interest in Wi-Fi sensing, Task Group IEEE 802.11bf was formed to develop an amendment to the IEEE 802.11 standard that will enhance its ability to support Wi-Fi sensing and applications such as user presence detection, environment monitoring in smart buildings, and remote wellness monitoring. In this paper, we identify and describe the main definitions and features of the IEEE 802.11bf amendment as defined in its first draft. Our focus is on the Wireless Local Area Network (WLAN) sensing procedure, which supports bistatic and multistatic Wi-Fi sensing in license-exempt frequency bands below 7 GHz (specifically, 2.4, 5, and 6 GHz). We also present an overview of basic sensing principles, and provide a detailed discussion of features defined in the IEEE 802.11bf amendment that enhance client-based Wi-Fi sensing.

"actual 2D animation" being limited to pen/paper on animation cels is a narrow definition. Shows such as Primal are digitally animated using modern techniques, but it's still hand drawn rather than being fully puppeted like many other shows

1. That's Valve's prerogative, not the developer's. If they're not partnered with Valve they may not have had the option to enact pre-purchases. [1]

2. The game has no DRM and Steam preorders (in my experience) download the game files so people can play instantly on launch day. (They call it 'preloading'). For a game as highly anticipated as this, it'd likely just be cracked, leaked and pirated the moment preorders came live.

For me, the original Hollow Knight wasn't exceptionally innovative or original, but did set an extremely high bar for polish and refinement over similar indie games. I've played a lot of metroid-style games and Hollow Knight has super tight movement, and expansive and thoughtfully interconnected map, simple but addictive combat, great art and design, memorable music, etc. Plenty of other games have some or most of those things, Hollow Knight just executes them at such a consistent level of craftsmanship that it stands out.

Did I, or did I not, have the option to fast, or not to fast?

Did I then pick one? How is that not proof of a choice? Who or what else made that choice if not me?

If you poke me with a needle, I move, that is not a choice because it's a forced choice, that's essentially what animals do, all their choices are forced.

That's also what free will is, free will is not a choice between a good and bad options - that's not a choice. Free will is picking between two options that are equal, and yet different (i.e. not something where before options are more or less the same, like go left or right more or less randomly).

Free will is only rarely exercised in life, most choices are forced or random.

> They said animals show choices

Given what I wrote, do they actually show choices? Or do they just pick between good/bad or two equal options?

>step one is fix the corruption.

Easier said than done and you know it. Meanwhile the government is making your car illegal in 10 years, but your job will still need you to be at work by them somehow, that's your problem.

> That can only happen when voters care about their side more than other things.

That's why corruption isn't going anywhere because society is more fragmented and partisan than evet due to the ever increasing number of fires that need putting out. You can't get your county to pull non existent money out of thin air for a 20 year rail project when there's a war next door and million of pensioners and refugees that need money right fucking NOW. So taxman and money printer go brrrrrr.

>rails are expansive but they are timy compared to most of the budget and an investment that saves you (roads which I bet your government pays for)

Yeah but the roads are already there and so are the cars, and people's homes and workplaces were built around that existing road infrastructure. You can't tell them to fuck off somewhere else because in 20 years a rail will be there. Once a you build a dense, car-first society over decades with no space for rail, ripping that off and replacing it with rail is impossible in the west. The nimbys alone will kill it even if you had money to build it.

We have new rail projects built but they're cross country in wilderness, not inside the city where its needed daily.

If your only dataset is 2008 to 2010, yeah your conclusions are almost certainly garbage. Likewise if your dataset is 1999 to 2002, or just the year 1987.

There will always be something going on, but there won't always be this specific thing going on, and if 100% of your data comes from during one specific crisis (nonetheless multiple concurrent crises), then it is 100% useless. Even with longer periods of data, reconcilliation with longer trends is technically challenging. We've had enough recessions to correct for them in our data, but until we've had a half dozen global pandemics you can't use pandemic data in your analysis.

Author here. No the article is not generated, it's dictated. This was more of a shower-thought (car thought I guess, since i was driving) that I dictated and fed to deepseek to punctuate and structure for myself. When it's a quick, short, unrefined article, I post it on the byte size section of my blog. So no, these are my words, and you can find it on some of my old comments where I mention how I've been testing AI editing and it's a hit or miss.

It solves a problem for Stripe : potentially evading some incoming regulations in payments in the UK/EU (and U.S probably).

Regulations in payments tend to be very technical, and inserting some crypto/distributed plausible deniability in the mix could get them 5 more years of delay (until the next generation of regulations). It will depend on how those regulations take shape in the coming months.

I encourage everybody to work with service workers to encounter the horror that can be service workers gone wrong.

Pro-tip: Use Serwist (https://serwist.pages.dev/), don't learn Workbox. Serwist has beautiful Vite integration for preloading app chunks from a build manifest. Learn all the different caching strategies. Consider dynamic caching strategies, eg. switching between two strategies for a specific cache via messaging throughout the lifetime of the app. Deep breaths. Have a service worker kill-switch in case things go wrong.

> there are already more cheese varieties around than anyone could eat in a lifetime.

If that's what you think then why don't we just close down all the studios and instrument shops. We've got enough, no need to keep producing it?

You can copy and distributed the cheese freely but the farmer still has to spend money taking care of and housing the cows, milking the cows, going through the whole processes of churning and pasteurising and everything else, then packaging it and disturbing it to where you can initially find it.

Now after all that you come along and make your perfect atomic copy and walk away saying "Well screw you, you should have no say in any of this..."

Then what? What's the incentive to produce and distribute new cheese? You really think it doesn't matter because you already have cheese from the past? Because there's a lot to be said about cheese that captures the spirit of the zeitgeist...(Ok that last bit didn't work in the metaphor)

The original problem is the one you're thinking of as modified, since the original problem was about a real-world game show, and the rules of the real-world show in question included Monty Hall (the host) opening a door that the player hadn't picked and which did not contain the car. The problem assumed familiarity with the game show, the clarification is for people who didn't watch the show.

I'm not saying current political conservatives are the cause, Bork was hugely influential beyond traditional conservative circles, particularly in antitrust law.

If you read Bork's work, especially The Antitrust Paradox, and if you study the caselaw prior to and post 1970's, you'll see a stark difference.

It was really a conservative idea at that point but I'd say it's more neoliberal, which has a strong backing in the democratic party and has for decades, beginning with Carter.

The per se analysis and application, particularly, is just massively different from the pre-Bork era. He's the single largest reason that the three main elements of cost, quality, and quantity as a standard for antitrust analysis has eventually boiled down almost entirely to cost, partially because it's so much easier to measure but also because he advocated for it as a mechanism to measure business efficiency.

One of the big problems of this is the change in fundamentals since Bork was writing in the 70's, particularly with union membership declining so heavily. He was countering a very strong and powerful union system and factored that into his analysis, and we just don't have that in the private sector any longer.

I've been working on a paper for a while about theoretically adding in wage and labor market analysis into the mix, particularly with monopoly and monopsony situations, but it's kinda stalled since I've been clerking.

Honestly, read the guy's book and read some cases if you're interested. You'll see it fairly quickly.
