Piperazine was a drug so synthesis at volume is understood. But you think a good write up of this compounds applicability would show how a scale system, eg at a fossil fuel power station could use it.

> Performance metrics achieved in this study underscore its practical significance. The tandem amine scrubbing and electrolysis system records an energy efficiency correlating to approximately 48.8 gigajoules per tonne of CO produced. Such a figure aligns favorably against existing technologies, presenting an economically viable and scalable pathway toward carbon-neutral chemical feedstocks. This milestone energy efficiency could catalyze momentum in the commercialization of integrated CO₂ capture and utilization systems.

I may have my scale wrong but that looks like 13Mwh per tonne of CO2.

I've been Linux only for around 15 years personally, but I don't push it on others.

A few weeks ago I told the company our few Windows machines are going to be sunset-ted. No push back (other than a request to have one for the odd thing - but will do that in a VM. Even the devs who have always been on Windows are up for it.

At home my kids use computers for playing and making games. Windows was the path of least resistance. I realized it'll make essentially no difference to them to switch to Linux. And boy do kids adapt quickly.

So thanks MS, sincerely. I've never both worked and lived completely Windows free, but your encouragement to drop Windows has made me realize how painless it is, and I should have done it years ago.

Edit: One guy is on mac. And always will be. No issue there IMHO

Expected array gain: ~39.3 dBi / EIRP: ~63.1 dBW

Tx power: 1 W per antenna

Yeah... so free space path loss at legal frequencies for hams this thing can transmit on is ~283dB. Neat idea but consider me skeptical. Having said that I can see some interesting applications for this kind of gear, EME seems overly optimistic though.

As a corollary, working with RN quite a lot, we just built an app for a client that was end to end finished and fully approved to both apps in a month, including pretty deep feature work and redesigning multiple screens. It includes the latest liquid glass native UI as well.

RN is a mess to get into, but once you've found a good stack you can really fly. We are working on a starter kit based off our experience that I think should represent the best possible starting point once it's released sometime before the EOY.

Retro fit is clearly a preferred path for a new approach given ship life spans and size of existing global transport fleet.

My gut objection to the container approach taken above in the first link was existing container locking mechanisms for ships can struggle in severe weather to keep the boxes on the boat .. additional forces from a sail (in good weather) might well mimic the forces that break stacks in bad weather.

Your point is well taken, I might suggest that container ships could be segregated into fast and slow cargo and that might help somewhat with total fleet fuel consumption. (pure spitball notion).

I'm not sure this is the correct perspective on voting. Voters are often passionate about one or two key issues - crime, Israel v Palestine, cost of living, immigration policy, coal towns, Ukraine, military spending, or whatever is most important to them.

If they voted for Trump it doesn't mean they agree with him on immigration and crime. They just have to think it's less important than the positions they do agree with. An effective argument to win over those voters isn't "you're evil and should have better opinions," it's "immigration policy is important too and this one is really bad, plus Trump is doing a bad job on your pet issues."

As a commercial pilot, your response is a little glib and kind of ignores the meaningful advances that have been made with D-ATIS, ADS-B In, CPDLC, DUATS, XM weather, etc. Voice is absolutely not perfect, analog FM audio often comes through garbled, pilots have to wait their turn on a busy single-user channel for timely information, etc.

This doesn't even begin to touch on the complexities that will come from full integration of drones and eVTOL into the national airspace, which will absolutely swamp a one-speaker-at-a-time analog FM comms system.

> The documentation is super terse. Very few examples.

I agree. OCaml is a complex language with very beginner-unfriendly documentation. In fact, I would even say it's unfriendly to engineers (as developers). The OCaml community prefers to see this language as an academic affair and doesn't see the need to attract the masses. E.g. Rust is an example of the opposite. It's a complex language, but it's pushing hard to become mainstream.

That's true, sure. My response to that is in React you have JavaScript & JSX and there are clear boundaries. It's not mixed. I don't write

<for ...>

In JSX I write JavaScript that returns JSX:

{data.map(node => <Element {...node} />)}

^ ----- JS ----^ ^ ------ JSX -------^

or

const elements = data.map(node => <Element {...node} />) ... <div>{elements}</div>

Really the most obscure syntax there is the splatting but it makes sense to you when you realize that JSX is just syntactic sugar for JS:

data.map(node => React.createElement(Element, { ...node }))

Indeed, leaving Windows behind for the odd application is easy.

With the depreciation of my late 2017 Intel iMac 5k incoming, i however wonder how to ditch macOS for Linux and keep the one odd Mac App I kinda depend on - ideas welcome!

If you’re wondering, the App is MoneyMoney and keeps track of all bank accounts automatically, sorts all spendings into categories etc.

There simply seems to be no equivalent, and running Mac Apps on Linux just doesn’t seem to be a thing yet (at least in a half-viable way I know of, and yes, I at least read about Darling).

Again, if anyone does have a pointer (running macOS virtualized? What’s the status there?) would be much appreciated..

Edit: oh and i fully intend to keep using the iMac, its an i7 with 64GB RAM and the 5k display is still so gorgeous to look at.

I think you really pretty fundamentally missed the point of what he's saying. Perhaps you've never had to confront the full brunt of the bureaucracy of a large-scale medical provider.

If you've got a serious condition, you really do need to have a patient advocate, whether that's yourself or a family member or someone you're paying to fulfill the role or some combination thereof. The medical systems I've encountered for non-trivial care (US HMO, US PPO, Belgium, Norway) just aren't designed for holistic patient care. Each department does their own thing, and it's just luck if there's someone watching over the whole process from the individual patient's standpoint.

Perhaps you took exception to the comment about looking for an expert instead of a newbie (a resident, in the text) working on the author's 9-month-old. One could argue that that's a different issue than the general need for a patient advocate. Fair enough. But if I were watching out for my 9-month-old, I'd definitely want to ask about the track record of each of the doctors in the room. I mean, sure, new trainees need to practice somehow and all, and there's a tragedy of the commons there. But I certainly wouldn't brush someone off as "absolutely entitled" just because he wants the best care he can get for his 9-month-old.

Find it a pity that the decision was to remove them instead of owning how the ranking is made. it’s going to be very very hard to differentiate between bots and humans at the dns query level, if possible at all. DNS magnitude is about the dispersion of source ips/networks and if this is a distributed bot net, it makes sense. and it’s about 1.1.1.1 queries, not overall dns queries, which they couldn’t possibly obtain. See this more as proof of the impact of these botnets, which I found super interesting. Removing them just makes it poorer imho.

I just don't get these comments about syntax...

Just taking the first example I can find of some auto-formatted OCaml code

> uninvited advertising is not normally equated with a better customer experience

As Jobs understood (per TFA), pushing ads degrades the user experience - the prime differentiating factor for Apple products in the first place, and what attracted many people to the platform.

It's bad, and it's probably going to get worse as Apple's services businesses increase their share of revenue and exert expanding influence over product design within the company.

Banning Apple from leveraging its platform for advertising Apple services might help, but the fact that we have arrived at the point where we have to rely on antitrust enforcement to make Apple products less intrusive and user-hostile shows that the company has lost its way.

> Modern iPhones don't come with a music player. They come with a music store

Unfortunately, requirements that Apple provide a choice to install Spotify rather than Apple Music, or Kindle rather than Apple Books, on a new iPhone doesn't fix the problem.

What does "revolt" mean, exactly? I'm a developer myself, so I'd like to know what I would/should be doing?

Keep in mind that a lot of Mac developers have iOS apps too, so they're accustomed to app review.

Nature is cruel. Every living thing wants energy for itself, but there's only so much to go around. The leaves cry out in ultrasonic frequencies as they're harvested, and then we add insult to injury by drowning them in salad dressing before we chomp away blissfully. You want to live, just like they did. So you eat. If only the universe had infinite resources to go around, but instead the march of entropy leaves us fighting over an ever shrinking pie.

There was discrimination for very very long periods of times. For example, Jews weren’t allowed to hold many professions for a very long time in Europe. Black people in America were slaves and continue to feel the effects of discrimination today. It still exists in other cultures today. The idea that capitalism solves discrimination magically does not appear to be borne out in any evidence I can find. Economic efficiency takes advantage of societal changes and removal of discrimination. Not the other way around.

I don't think it is ridiculous to flag topics like this.

The problem is that topics like this are incredibly hard to keep civil, and the "HN factor" ("prominent" people involved chiming in) is not really there, either. It also frequently ends up in the exact same repeated arguments (at best).

Personally, I'm not flagging posts like this and I'm always very happy when the tone stays civil and the discussion interesting, but I can see why people would.

> The Secret Government

True. American Thought Control is waging a secret war upon us all, attempt to reduce the world’s population and insure their cult of Power is dominant (no other culture of Power can find their leadership, and they can destroy anyone who tries.)

I repeat my claim, these are people who have the Power to travel among our minds. Further, these are the deep dark ruthless elite of a culture you don’t even know exists who can travel through and listen to every thought in the mind.

> UFOs and extraterrestrials

True the cover up, false the “working with”, and can’t say about Kennedy.

The working with is false.

In the 40s/early 50s (before my time) they greys intentionally crashed a small craft (like a kite by comparison) simply to tease us, they wanted to say hello in their own due time. In the early 80s the US surprised them by striking them with a sea based missile (some live in the deep ocean.) These are essentially frag bombs which crudely knocked the craft to the ground. They weren’t expecting it. Not something that could happen again. It was recovered with live yet damaged crew. The greys then actually arranged a meeting (through the mind) to bargain for the recovery of the living crew. I know it’s hard to believe these advanced creatures could be naive, yet they were tricked into a trap.

Some accounts claim that a third alien species was helping the humans capture the “greys”, though that is a false account. You will not understand or accept that humans have the ability to travel among and control other human minds. These elite were running the trap (not the physically present men, so their deception was not evident.)

Btw, Ion, the leader of the crew was terminated after some years of abuse, in the end refusing to cooperate, condemning and cursing men (Americans) for their treachery.

> Government-created viruses

I cannot comment so much on “government” rather “those bunch of men run by the voices in their heads.”

These are absolutely waging a biological warfare upon us, thinning us out whenever possible.

Would you believe me that Covid was from Wisconsin? There were seven viable strains, remember when New Zealand was covid free until a new mysterious strain appeared? Yes, thought controlled America is waging a biological warfare upon the world.

> Other conspiracies > … and the manipulation of media and mass consciousness.

Yes. Most obviously.

I haven’t read the book, only the AI summary though his accounts are consistent with my own experience, only mine is more recent. I was indoctrinated in 2008, became hostile soon after and fight with controls to this day. I’m working on a book myself, “The Exogenous of Power”. Maybe you will hear of it some day.

This list of conspiratorial evils doesn’t mention “mass pedophilia” or rape war.

Hospitals are full of 'life and death' situation. If everyone were to behave like that, things would stop working or be severely slowed because you can't work correctly when you got that guy breathing on your neck constantly. You lose time answering to load of demands from people getting angrier and angrier because they feel that they don't get the care they need. That makes you angry. Other people are getting less attention, they get angrier.. Etc etc.

I believe you have the right to say it when things are not right, but there is a fine line between that and the behavior he described.

And he wrote that he went to an expensive hospital, this isn't some low tier hospital filled with under qualified, under staffed personals.

That’s interesting. I’ve always held SvelteKit in high regard for greenfield projects because it balances capability, developer experience, and performance, but I’ll have to give Marko a look. I’d love to see a similar deep dive into Electron style desktop frameworks since that space still feels underexplored compared to mobile. I honestly wouldn’t know where to start for a video game interface, and that bothers me.

Just want to reiterate what the sibling commenter said, it's dead on with my experience.

Static typing would be the main thing teams would've been better off with. I was big on dynamic languages, love Clojure/LISPs and still work with Ruby and JS today, but you just can't trust 100 developers with it. Last company I worked for I ran the dev team and did some bug analysis: conservatively 60% of bugs were things a simple static type system would've caught.

Very few business logic bugs. We had loads of tests but these simple bugs still popped up. Someone in team A would change a method's return type, find and replace in the codebase, but miss some obscure case from team D. Rinse and repeat. Nothing complicated, just discipline but you can't trust discipline on a 500k LoC codebase and a language with no guardrails.

Performance would've been the other main advantage of static typing. While most people think their Rails app will be IO-bound forever that's really downplaying their product. In actuality every company that mildly succeeds will start to acquire CPU-bound workloads and it'll come a point where they are the bottleneck. One might argue that it is at this point you ditch Ruby but in reality no one really wants to run a polyglot company: it's hard to hire, hard to fill in gaps, hard to manage and evaluate talent.

People underestimate the impact of performance on the bottom line these days with phrases like "memory is cheap; devs are not". Like the sibling commenter put it the monthly cloud bill on that last company would've paid about 20 dev salaries. Most of that was for the app servers. That for an app that served about 500 req/sec at peak. You can imagine the unnecessary pressure that puts on the company's finances.

Better choices would've been Go, Rust, even something on the JVM.

> Sure, it is absolutely true that better lifestyle and diet has a huge effect.

not for me. My cholesterol was hovering in the high 200's, then finally hit 300 and I completely freaked out, radically changed my diet, and lost 22 pounds (from 180 to 158).

What did my high cholesterol do ? It did absolutely nothing. ticked down to like, 280.

So I'm on the statins. my total cholesterol went from high 200's to about 150 in a month and was impacting my liver function. so we reduced the statins to a very low dose (5mg three times a week, crazy low). My total cholesterol hovers around 200 now. My cardiologist tells me that the conventional wisdom of "diet and exercise" is almost entirely disproven to have any meaningful effect on lipids these days (though i havent researched deeply).

Disagreement is censorship?

To make this more substantive and on point, I get the argument you are making -- if there were no "illegals" here, then there would be a stronger job market for the lower end of spectrum. That is true to some degree. It is healthy to discuss the issue, but the discussion should be based on all the facts, not some of the facts, and not made-up facts.

Secondly, the article of the thread was talking about how the federal government is spending tens of billions of dollars to put masked goons in unmarked cars, often with no identification of who they are, jumping out of cars and abducting people. If you think this is just about rounding up people who came across the border illegal, you are sadly mistaken. This is about asserting power and terrorizing the regions that didn't vote for Trump.

There are plenty of other undocumented workers in red regions. There are many red states with higher crime rates than the cities ICE is targeting. This isn't about law and order -- it is about intimidation and centralizing power.

It would be hilarious if the consequences weren't so dire, but all the states rights people apparently have no problem with Trump exerting his will in states' business just so long is it is harming "libs".

And there's a 50/50 chance they'll use the right tool for the job. I tried the math question above multiple times on gpt5 and it gets it right about 50% of the time. If i ask to "try again" it usually gets it on the 2nd or 3rd try. Most times that it's wrong, it's not far off but it looks deceptively accurate at first glance.
