Quantum Fuse is a theoretical and experimental project exploring the feasibility of creating a two-qubit quantum computer using accessible and affordable components. Our unique approach utilizes quantized mechanical vibrations within synthetic quartz crystals to serve as our qubits. The project is built around an ESP32 microcontroller, a green diode laser, and an AD9850 DDS module.

Never trust anything written by lawyers/economics/MBAs on climate change - only analysis by chemical or mechanical engineers is worth reading.

Just so we know if we should keep reading, which one are you?

Methane pyrolysis is an old technology from early days of oil refining for production of hydrogen & Ammonia/fertilizer/Methanol. it yields half as much H2 than SMR/ATR so it can't compete on cost, unless there is carbon tax/CO2 penalty.

It's not appropriate to call it "technology," in the same way it's not appropriate to call "combustion" a "technology." There's a very wide variety of technological solutions to realize this family of chemical processes, and some are going to be better than other, depending on the use case or scenario. The report actually covers those pathways reasonably well.

Also, coke produced by pyrolysis is lower quality than that produced by Delayed Coking of crude oil refining.

Ideally, you would not be producing coke at all, but a higher value material. However, even coke will be of much higher purity than petcoke (before calcining) -- i.e. it would be intrinsically zero-sulfur carbon material, - but I'm not sure what applications it would have that don't involve production of CO2.

But obviously the carbon co-product should have value, which would provide a cost offset to the hydrogen. With a high-quality co-product (> $1/kgC), this offset would be significant enough to provide that hydrogen essentially free of charge.

SMR and ATR generate significant amounts of CO2 (~10 kgCO2/kgH2), which does not provide a cost offset, and in a fair world would instead incur a significant added cost.

Electrolysis requires 4x more energy (also electric, not thermal) and does not have a marketable/valuable co-product. Just on the energy cost alone (50 kWh/kgH2 * 0.12 USD/kWh = 6 USD/kgH2 > 40 USD/MMBTU) electrolyzer hydrogen is not competitive with any of the above.

Commonsense should tell you e- generated by H2 can't compete with CH4, because Ch4 is the feedstock & H2 is the product!

Didn't parse this statement, sorry. Can you rephrase?

I also don't want mood playlists, the majority of the time. I'm saying I use AI generations for exactly the opposite — so that I can explore and listen to things that are more intellectually interesting in the ways I find intellectually interesting, because the human music it's easy to find is common denominator music.

The way you describe AI ('continuous stream of auditory stimuli') is the way I'd describe Spotify. Sure, you could use AI to make a faux Spotify, but, like, why would you? The popular stuff already has saturating supply, and it will sound much better than an AI generation.

> What is the incentive of someone to create an app and just pay for all the hosting involved?

If you're creating a social app, website, or whatever, you still have to host all your users' data regardless. This is just about the protocol you use which enables universal compatibility, meaning users have the choice to store elsewhere.

> Also, does everyone need to have their own domain name in order to have an identity cuz that seems like a non-starter.

Not really. Bluesky is a good example; when you first sign up it does it for you under their own top domain by default iirc, but the great thing is you can actually use your own domain.

Readers might be later surprised to find that there are vectors which are not lists of numbers

I see this sort of thing as being similar to how physics is taught. Year 1: Atoms are indivisible. Year 2: Well, no, actually, we lied, they consist of elementary particles called electrons, protons, and neutrons. Year 3: Well, technically the protons and neutrons aren't indivisible either. ... Year 10: OK, fine, we have no idea. Your turn, help us figure this out.

Nobody starts rambling about quarks and gluons in grade school, and few practitioners will ever need to deal with them at all. Likewise, for most people looking to get their feet wet in ML, vectors are a 1D list of numbers, matrices are a 2D list of numbers, and tensors are lists of numbers with any number of dimensions. Definitions that are incomplete at best, but good enough to get started.

I have AirPods Pro (and like the B&O EX much better, personally), but I wouldn't use them for bass-heavy stuff even compared to over-the-ear ones, let alone a system with big woofers. It's just not the same as filling a room, and not just in an "amusement-park" way.

Your pithy comment and thinly-veiled insult don't withstand scrutiny before a simple mirror. If Capital does not need humans, then humans do not need Capital; viewed against another mirror, if Capital does not need humans, then where does Capital derive its value from if not the lease of its assets back to humans as a form of wealth extraction from the working class to the asset class?

If all humans are asset holders, then where does Capital arise? If all wealth has been extracted from the asset-less into the hands of Capital, then why does Capital need humans?

I can keep cutting your particular barb in any way I choose, but the answer remains the same: Capital, while a useful tool in improving society over the past few centuries by migrating away from Feudalism and Monarchy into Capitalism and Democracy, is no longer useful (or even ethical) now that its incentives are diametrically opposed to human prosperity for all except the asset class.

I have an older Vizio TV, was never connected to the internet but it does have wifi. Last year it started freezing up a lot, and I read that some people had resolved that problem by removing the wifi module. Since I never used it as anything but a dumb screen, I figured why not try it. I opened it up and did that, and it's been stable ever since.

More than a few dozen people stand between where we are and a carbon-neutral future/alt-history.

But there were some important tipping points that have pushed us into our current do-nothing trajectory. The stolen 2000 election was a notable one.

We've already hit 1.5C, by the way. Hold on to your butts.

What about Cara, Vero and MeWe?

This are just the last three Social Media I subscribed in the past and range from Stagnant to Pretty Much Dead.

I suppose that the problem is that if you already have 1000+ followers on, say, Twitter or IG you try posting the same stuff in parallel on both... after 1 month of doubled effort you notice that your followers on the new platform is an order of magnitude smaller... you want to stop double posting because it is too time consuming. Guess which one you will opt out of?

I think you're assuming that dichotomy. There was an observation that Trump supporters derided liberals for loving biden. The observation pointed out a false equivalence, "the other side is doing the same thing", we love Trump, so they must love their leader too.

Or, do you some sort of systematic evidence that evaluates the politics across all of bluesky in comparison to X? I don't think there is such evidence to know that bluesy is the polar opposite of Twitter.

Now do Cuba. The American Mafia was running Cuba by 1959 because, casinos and American tourism. Fidel Castro's revolution was genuine and did reflect the desire of most Cubans when it kicked the US Mafia out. The mafia expressed interest in ousting Castro and getting their casinos back. Bay of Pigs was a failed CIA+private mission whose motive was america:demorcacy:'communism' to which I add :mob. Las Vegas was their backup cope.

Then in 1962 suddenly another motive was added :USSR-missiles. The US blockade of Russian warships probably loaded with ballistic missiles on their way to construction sites in Cuba, was the closest brink of war yet. My Dad (ARMY) was on alert and packed to go.

With that resolved and no USSR missiles in Cuba the working motive for opposition fell back on (because Castro, Communism) and its economy was hobbled for years until neutral worldwide investors besides the USSR established ties. To this day Cuba is still on the edge with the lines shifting back and forth.

As has Iran since the Shah dynasty ended and American hostages were taken. So Cuba and Iran have lines stretching back into the distance. Probably you and I are young and it all seems so ancient. But Iran is a wealthy country now and (like us and the CIA) and it is now 'on our watch' to make sure money is not being funneled into the wrong places.

This nuclear thing annoys me but I'm a 'radical'. Aside from sweetheart deals and that 'other' country the US gave The Bomb by supplying their initial fissile material... since the USSR split anyone with MONEY has been able to acquire 1,2,3,+ bombs if they want them. "So and so is two weeks from having a Bomb" is generic Boomer slop to stoke fear and justify anything. And by all means if you have uranium, centrifuge uranium. And build out nuclear power.

Don't reply with an answer and place yourself in the crosshairs. But think on or find out for yourself, what number between 3% and 99% was Iran aiming for? If the number is on the higher side don't think in terms of [stupid] nuclear war, think in terms of money being wasted and having to deal with the most sordid people in the world to sell it. A bad direction. Things like this are both funny and sad, and hint at a world that might have turned out differently, better ( https://web.archive.org/web/20150518180531/http://en.wikiped... ).

> We can only guestimate the impact:

> 1,500 downloads every single week

> Being conservative, maybe 20% are actively in use

> That's about 300 organizations

> Each one probably sending what, 10-50 emails daily?

> We're talking about 3,000 to 15,000 emails EVERY DAY flowing straight to giftshop.club

Those figures seems crazy to me.

They assert that behind a single download from NPM is a unique organization.

That's insane.

A download from NPM is just someone (most often something) doing _npm i_.

Given how most CIs are (badly) configured in the wild, they'll _npm i_ at least once per run. If not per stage.

So those 1,500 downloads per week can come from just 2 organizations, one with a dev POCing the tool, and one with a poorly configured CI.

And the official repo has 1 watch 0 fork and 2 stars: https://github.com/ActiveCampaign/postmark-mcp

Sure the issue raised around MCP and supply chain is big, but the actual impact of this one is probably close to 0.

Why do we continue to prop up these companies when there are ethical alternatives? We are rapidly replacing all experts with AI trained in their data, and all the money goes to the AI companies. It should be intuitively obvious this isn’t good.

I'm not sure who is the outlier but I'm like the GP says. Was into music and stereo systems as a teen and into my 20s. Now, I just listen to whatever is on the radio in the car. Even streaming is too much hassle most of the time. I will go to YouTube music occasionally when I get the urge to listen to a specific song, but that's pretty rare.

I wonder to what degree it’s actually necessary to explicitly manage memory spilling to disk like this. Want unified interface over non durable memory + disk? There already is one: memory with swap.

Materialize.com switched from explicit disk cache management to “just use swap” and saw substantial performance improvement. https://materialize.com/blog/scaling-beyond-memory/

To get good performance from this strategy your memory layout already needs to be optimized to pages boundaries etc to have good sympathy for underlying swap system, and you can explicitly force pages to stay in memory with a few syscalls.

140k places you in the top 1-2% of the entire planet in earnings.

I can think of 2 US companies I know of off the top of my head that deliberately hire Europeans since they get talent at a steep discount (especially if you pay them remotely). From what I've seen Ukraine and Estonia are considered goldmines of cheap talent. I doubt they are the only ones.

Bald speculation and opinion would be that this massive imbalance between earnings is causally tied to merit to a degree strong enough that we can confidently say European software engineers are as a whole a whopping 50% less competent than US counterparts. This to me is ridiculous, not because it sounds offensive or anything, it's just obviously untrue for Europe. This is just how we've set up our geopolitics with downstream affects being massive imbalance between earnings of countries.

See, that's a good question, but it has an answer: first, they took a priced round, and those investors will need to see a return, and second, when the funding runs out, someone is going to have to put more money in --- substantially more money --- to keep the lights on.

What's probably true is that if they found a stable source of revenue they wouldn't have to answer these kinds of questions. But this is just back to my original point, of "I don't see how this is going to work", because I don't see how they're going to do that.

I'd be happy if someone jumped in and set me straight with a clear and plausible plan. To me, though, from the information I've seen, it looks like the premise here is that they're going to raise again, and to do that they're going to need to demonstrate accelerating growth, which they starkly do not have right now.

Then again, that stretch also has Gary.

Having grown up in that area of the Midwest, I largely agree with the author's categorization, except that "people on their way to somewhere better who got tired and decided this was good enough" describes a LOT of the midwest, not just Indiana. Significant chunks of Michigan, Ohio, and Missouri, most of Iowa/Kansas/Nebraska, etc.

If you read the history of westward expansion, "got tired and decided this was good enough" is literally true for how much of the area got initially settled (by white people)

Yeah, the constitution... let's talk about that for a minute.

The feds own immigration policy and enforcement. For a city to declare itself a "sanctuary city" is, basically, a refusal of federal authority. Yeah, previous presidents didn't make an issue out of it. That doesn't make it anything different, though.

And the federal government does have the right to bring in federal troops to protect federal buildings and federal officials.

But of course it's not that simple. That presumes that Trump's actual reason is the stated one, which is not a reasonable assumption. It presumes that all the troops will do is protect federal property and workers, which is unknowable at present.

And it ignores the ruling that Trump bringing troops into LA was illegal. If that was a federal circuit ruling, well, Portland is in the same federal district, so it's current law there. (Does anyone know what the current situation is with that case? Does that ruling stand?)

Look, don't take any of this as an apology for Trump. But he does have the legitimate authority to enforce immigration law. If the troops wind up doing more than protecting the people who are doing that, then he doesn't have the legitimate authority to do that.

Interesting. Ok just saw this https://github.com/bluesky-social/pds

> Self-hosting a Bluesky PDS means running your own Personal Data Server that is capable of federating with the wider ATProto network.

So pds (personal data server) is like the container where you chose to store the data and it follows a certain standard.

If the container is hosted is bluesky, i still consider it a "bluesky api" but I understand the nuance better now.

You've got three tools, mutes, blocks, and lists. Yeah, there's no centralized algorithm that does it for you, it'll take a couple days of actual effort, but it's extremely easy to prune your main feed into looking how you want it to look.

I really don't think so. Punk had exploded after the Summer of Hate and in its wake we got Talking Heads, The B-52's, and Blondie at CBGB's. In parallel we have early Joy Division in Manchester which is going to inspire U2 to eventually become the biggest band in the world for the next 20 or something years. Martin Hannett is going to be a key figure in the development of EDM with his use of samplers and, "using the studio as an instrument." Check out the beginning of, "Transmission." He'll later go on to produce The Happy Mondays who are, "the" seminal Manchester dance group in the early 90's in lieu of an army of Stone Roses fans throwing lemons at me.

If you look at how Johnny Rotten was listening to Neu! and X-Ray Spex (as well as The Monkees and Herman Hermits) and what Bowie was doing after he moved to Berlin with Iggy Pop it's not outlandish to say that Electronic Music wouldn't have existed without being preempted by Punk, Glam, and the emergent, "not progressive" guitar music of the 1970's especially in how it paralleled the development of Krautrock. Disco didn't evolve into EDM; Disco gave DJ Kool Herc a set of turntables to invent Hip Hop with. Techno literally came out of, "a certain guy who might be called Gerald" listening to Kraftwerk; Afrika Bammbatta's, "Planet Rock" samples Kraftwerk directly.

Then he installed some kind of filter for his kid that broke everything.

It would be nice to have solutions that protect kids from really harmful stuff, but YMMV on what's harmful. Lies, CT's and hate speech are harmful IMO.

If current technologies can't solve the problem for political/societal reasons? We need better technologies.

Improving technology is easy. "Just fix everything that's wrong with the society and the problem will go away" isn't.

It's way, way easier to improve solar panel and battery storage tech until fossil fuels are completely uneconomical than to get the entire world to abandon fossil fuels while fossil fuels are the most economical source of energy by far.

I feel like this should really be SSH over QUIC, without the HTTP authorization mechanisms. Apart from the latter not really being used at all for users (only for API calls, Bearer auth), shell logins have a whole truckload of their own semantics. e.g. you'd be in a rather large amount of pain trying to wire PAM TOTP (or even just password+OTP) into HTTP auth…
