We know enough from the article to be able to ballpark estimate it. Heat capacity of aluminum is 0.9 kJ/kg °C, and the latent heat of fusion is 390kJ/kg. The temperature they heat the aluminum to is 700°C, from presumably room temperature around 20°C - so 0.9*680 + 390 kJ/kg = 1002 kJ/kg is going to be the basic heating requirement, or as near as dammit 1MJ/kg. Getting that heat into the aluminum and then maintaining that temperature during the print presumably introduces some inefficiencies (induction furnaces can heat aluminum with about 40-50% efficiency), plus they have to move the mass of aluminum around with their print motors... but the heat to melt the aluminum feels likely to be the main energy sink. Inductively heated, with good crucible insulation, 2MJ/kg sounds like a reasonable energy budget?

For a comparison, that's about ten times the amount of energy you use running your microwave to heat up a ready meal, for every kilogram of aluminum you want to form.
It's not asking you to change a physiological (can or can't you walk?) or emotional (are or are you not sad?) reality, it's asking you to change your rational self-perception. That's literally just a matter of changing your mind. Of course, if you still don't feel worthy, you have to ask why that is. Usually the issue is a critical environment, which you may or may not be able to change. I suppose there's value in reminding yourself that you have inherent worth and that the world can't take that away, but then you're still dealing with a world that wants to (and will take related action towards that end), for whatever reason.
I was not referring to the flag, but the downvotes, which indicate that a majority of users feel your comment does not add to the discussion.

You may prefer to say it in a different way than "smash 'em". But yes, if you violate the laws of the region you are operating in, there must be consequences. So, if you prefer: "Fine them. Jail them". Better?

And in regards of the chat control shit: Yes, this has been going on for decades now and pops up again and again. Originally it was pushed into the EU by the US via the UK. The crypto wars in the US appear to be over for now, but some European right-wingers are still dreaming about it.

But just this week the European Court of Human Rights has decided "chat control", aka weakening end-to-end-encryption is a violation of basic human rights.

This doesn't mean that the right wingers in various EU countries won't try again, but it's pretty futile. We, the people, won.
I agree - Technology should serve the individual fully and completely and not itself or its creators. Computing used to be like that. It still is, unless one hands their autonomy to large service providers.

Even if I spend time in front of my screen, I try to avoid slipping into nonsense.
> There is no good reason that this kind of content would need any client-side logic.

One such reason might be that it allows the developer to host their frontend statically, which usually is much simpler to set up and operate.

I would find it fair to appreciate that the author provides their service for free to the world. So while it might be true that their website isn’t fully compatible with certain client-side tools, that kind of support doesn’t come for free, and it also may not align with the goals of the author. (Which in this case apparently are educational ones, and not to maximise accessibility for a broadest-possible audience.)

> We’re certainly very lucky in many ways, but besides the financial aspect,

Your observations are valid, but you can't just sidestep the financial aspect of it, my dude. This is, like, 70% of the hardship of having kids from what I've found. Like this:

> If we need to drive 9 hours, we might break that into three days, and visit places that are about 3 hours apart. If we fly somewhere and it’s long, we try to go to immediately go to a hotel as close as possible to the airport so that we can all conk out if we need to.

Is straight up not possible for a family of 3 or more with a total household income of less than $150k in the US. On-premise airport hotels that aren't complete chaos are usually $200/night and many people in the US get hardly any vacation time (which is a whole other problem in its own right).
> It’s also ironic that the one thing HTML was designed for, namely presenting static content, is now deemed unworkable without having to run custom client-side code.

Because the content here is dynamic. It changes every 30 minutes, even if it's just the scores. HTML was not designed to serve dynamic content.
Ask HN: Home Network Setup Guidance
We were considering a tech refresh for a townhouse with a major vendor as ISP.

The main entry point is in the basement, and the thought is to use two MOCA extenders to get good coverage for the upper floors.

What are some management tools, guidelines, best practices, and vendors for setting up a such generic home network?
Zero rating, like when wireless carriers don’t charge for certain bandwidth but do for others.
There are issues with trusting a pci attached wifi device running a pile of closed firmware anyways.

If you're concerned about this type of thing discard the internal wifi card and use an usb-attached wifi dongle you can unplug to achieve a "wifi physically disconnected" state with certainty.

The other advantage is whatever firmware's running on the wifi dongle isn't going to be potentially accessing host memory over usb, which a pci bus master could theoretically do.
My understanding of FLW is that his houses are beautiful but impractical to live in. It would be great to see a comeback of his style if the problems with livability could be fixed, though in this case it seems like they couldn’t fix them all.
If you have a cabin or some natural spot you care about in the US, I highly recommend purchasing an actual USGS paper topo map. They are beautiful!
I sympathize with your concerns, but I also understand why museums are eliminating paper maps. Museums are trying to be more "green" and those maps always resulted in a lot of solid waste and litter.

> Do you think those stereotypes are really helpful in understanding geopolitics?

In some kind of way, yes. Cultures differ, sometimes drastically so. It is important to evaluate stereotypes based on history and their merits.

You said it yourself. Historically, Russia has faced many cyclic periods of expansion and reduction. They are currently being reigned by a patriotic figure with a record of dwelling on Russia‘s great past. Given enough time or an effective military response, chances are high that their next leader will be more favorable of peace.
That naming is blasphemy.
>It makes more sense to leave them as non-residential space, even if vacant for awhile before finally being reoccupied, and then to separately build brand new purpose-specific high rise residential buildings (which will be nicer than a converted office building ever could).

3. Use the money to finance the Utopia

I don't want to be too cynical, what Norway is doing is great, but I feel like whenever a case study comes up about why something works, ultimately it boils down to "money".

We can go full reductio ad absurdum and write "How Norway Built a free healthcare Utopia While Ethiopia is struggling".

Yes, exactly, I'm driving a compact and I often need to wear sunglasses at night.
Yeah, I think you're getting at the other big reason for zoning inflexibility: property value. High asset prices and a dearth of other reliable ways to grow wealth have caused many to prioritize the sticker prices of their houses over the livability of their neighborhoods.

One thing to point out is that different areas of the US are doing better and worse on a lot of things. This is a good example. It would be better to look at the different metropolises of the US when talking about various things like ev adoption, bike usage, etc. We have many areas of the US that have similar density to that of Norway.
The War over Burying Nuclear Waste in America's Busiest Oil Field
Well Gramscian hegemony requires the participation of the oppressed in their ongoing oppression... so I'd say that Amazon Prime membership qualifies. One obvious parallel with feudal lords would be venerating the super-bosses, the new 'lords of the manor' to keep it feudal, which certainly also seems to be happening. This is of course culturally backward-looking, the appeal of the strongman (in business or politics) should be waning, replaced by efficient tecnhocrats, but when you look around the world... Varoufakis may be on to something.
I think we’re actually in agreement. All I meant by that was that the fossil fuel companies have been happy to support things like an envisioned transition to hydrogen, biofuels, or nuclear power when that means it’s business as usual for decades until [hypothetically] some major change happens and our emissions will drop precipitously. Toyota is similarly happy to talk about how green they’ll be in 2040 while heavily advertising that you need a $60k ICE Tundra to drive to the office in the meantime since those have a much higher profit margin than the few hydrogen vehicles they can sell.

I strongly agree that nuclear is relevant for some last n% stuff but am hoping that the renewable boom will buy enough time to deploy it. As you noted, the capacity there has been on a reassuringly massive growth curve with no barriers to stop it other than politics.
I guess having your whole economy pretty wealthy based on fossil fuels and relying on US innovation in developing EV infrastructure helps.

This kind of reminds me of those “I’m debt free and have $500k savings at 25” type posts where the secret is having rich parents who pay for your college, network you into a good job, live at home and pay all expenses so 100% of salary goes into savings.

I mean, it’s cool for the poster, but I’m not sure how any of that is generalizable to me. Or to countries other than Norway. I don’t see Liberia or Oman (similar populations) drawing too many useful ideas from Norway.
I eat a lot of vegetables and fruits and those rarely show up in my dreams. Is there a hidden meaning behind that, too?

It’s an info theory thing. But nice try. Why don’t you propose something better? Besides what I already proposed anyway.

The ways to optimize/‘solve it’ all require degrees of rigor in information control and tracking that aren’t realistic given the market conditions and supply chains.

At least unless people stop being okay with paying for $40+ games that download 40G patches anyway. Which would require severe changes in trajectory of bandwidth availability, which isn’t likely.
Boston gets a lot of attention for its drastic changes even over the past century. Comparing modern Boston to its 1893 map:

* All of Logan airport, Winthrop, etc simply didn't exist

* MIT was a mud flat

* South Bay was still a bay, not a shopping center

* Obviously pre-interstate, railroads dominate the transportation focus

* Back Bay has already been filled in. The collection of mini-street grids is apparent in Back Bay and South Boston (Southie).

* The isolation of the Boston peninsula is less apparent at this point. E.g. Paul Revere's "one if by land, two if by sea" for the British heading NW to Lexington.

Why is this surprising? Big Pharma is not good at innovation so they buy and partner with companies that have done the hard R&D and they focus on commercialization, distribution and manufacturing. It doesn’t mean that pharma R&D is not being done, it’s just that pharma companies are not paying for R&D they are paying up for commercializable assets.
His vlog-like videos made it appear that way, but it's hard to say what the dude did or didn't do when the cameras weren't rolling. He did come a long way from being a restauranteur.

Ok, then let's assume that the European Court of Human Rights has been corrupted by evil forces from... erm... Mars... that want to ... erm... poison the planet by giving EU citizens control over their hardware and personal data. Or something?

Less naive, I guess.

I'm not playing your "sore losers" game. You are implying that all there is left to fight about is which mega corporations shall be in control of your personal rights.

Fine, if that's what you want.

I want to be in control of my data, and to be in control of the hardware I own.

This doesn't limit your freedom to have Musk, Google, Apple or whoever control your hardware. Give them your private keys. Give them your brain. All your choice and fine for me.

But my hardware stays my hardware, my freedom stays my freedom, and my data stays my data :)

tbh using signed 64 bit microseconds with ISO-8601 0000-01-01 as epoch has certain elegance to it and should cover fairly wide range of use-cases.
I'm kind of confused by this post. It talks about how this is an example of zero-cost abstractions, while actually showing the opposite.

The original implementation was grotesquely inefficient, it's a 172kB file! To fix that, they ended up manually inlining and duplicating 70 lines of code. And the optimized version is still 50x slower than grep --color would be.

Why was the original version so slow? Can't be due to the searching, given they were 4 orders of magnitude off from where they should be. It can't be due to this kind of batch oriented programming having more efficient memory access patterns. The data set is so tiny that it's all going to fit in caches. Something in the editor's internal data structures working better when the stages are not interleaved? That would be my first guess. Maybe making changes to the editor data structures invalidated the search state, forced each search step to restart from the start of the buffer, and you ended up with an accidentally quadratic algorithm?

There's clearly a real performance problem in their system that was papered over by copy-pasting some code, but that they'll inevitably keep hitting over and over as people write the obvious code, it seems to work fine, but then has bad performance in practice. The right thing to do is to either fix that underlying problem, or to make it as easy to write the well-performing version as the bad one. (E.g. have some kind of scoped "batch context" abstraction, which queues up the edits and then applies them in a batch when leaving the scope.)

Anyway, all of this makes the conclusion quite odd. The real moral of the story should be that CPUs are really fast, not that Rust is magical and will change the way one thinks.

Ask HN: How do you get by without an account with any "Big Tech" Company?
If you are not registered with any big tech company (apple, google, amazon, meta, netflix, spotify, etc.), what is your setup/how does your digital life look like? What do you use alternatively, and if you don't use a smartphone, what do you replace it with?

I'm curious as it seems to me that, it is quite unavoidable to have an account with at least one of these companies:

- If you use a smartphone you're pretty much bound to have a Google/Apple account or at least share data with them (if you use LineageOS/GrapheneOS you'll still propably use google services for push notifications etc.)

- media consumption (especially discovery and mobile use) seems very impractical without the subscription based services
Earlier, when restaurants wanted to increase prices, they had to reprint all their menus. So there was at least a small barrier to jacking up prices.

Now, with online menus, they can basically slowly keep increasing prices any time without any cost to them. No wonder they love it!

The worst thing is most of them don't even have actual responsive websites. It's just a literal PDF download that you now have to keep panning left right on a tiny screen.

> Meanwhile, Apple might have only 57%-60% market share instead of ~95%, but unlike Microsoft, it's actively blocking users form installing any other browser that's not Safari based and any app that's not on the AppStore, therefore doing even more damage than Microsoft was doing back in the days.

Okay so like: humor me. What is the damage incurred by the user's inability to install, for example, a true Firefox on iOS that uses their Quantum engine? I'll fully cosign that iOS' Safari has quirks that make it kind of annoying, very occasionally, like once every few months I'll find something that it does in a bizarre way that others don't. But I swear every time the topic of iOS' dominance comes up, there is a detachment of users out there who are simply furious that they can't install a web browser that doesn't use Apple's WebKit on an iOS device and I just... I do not get it. At the absolute worst I have never given even 10% of the shit required to where I would upend all my stored passwords and whatnot for the ability to even use a different WebKit based browser.

Now, granted, if this was the situation on the Mac, oh hell yes, I would absolutely be right there with everyone else and grabbing my own pitchfork. But on my phone? On my tablet? I dunno, am I weird for just not really caring?
Also it seems this is a task for which a model could be strongly fine-tuned. We just need a dataset of typical interactions...

> There needs to be some deception and a stronger consequence than a bad popup. Accidentally signing up for a mailing or buying something unintended, for example.

To the contrary, I think that intent to inconvenience people who don't make the choices the website wants but doesn't need the user to make can be enough to make a UX pattern a dark pattern in most cases. There's no need for a strong consequence, and there's no need for users to actually fall for the deception. There doesn't even need to be a deception to fall for.

Suppose that I shop online. I add an item to the cart. Then I decide that I don't want the item anymore, so under a minute later I go to the cart and click the cancel button. Fully transparently, the website tells me that I need to wait 1 minute after clicking "add to cart" in order to remove the item. The website always does this for items in the cart, but doesn't present the waiting as a feature of the service. It's not as if having multiple items in my cart means that I have to pay for all items vs. none at all; I can select which items in the cart to buy at any given time, so there isn't any strong consequence. But making me wait to permanently remove the item from my shopping cart is a dark pattern by default. (There are ways to make it not a dark pattern, such as transparently making the advertised gimmick of the online store "You need to wait 1 minute to remove items from the cart. Shop slowly and responsibly!". Wordle uses what would normally be a dark pattern - making people wait to play a game which needs no waiting - and turns it into a core advertised feature, a core charm point.)
I’ve worked on some large projects including refactors with Tailwind and my view is opposite. I can see how Tailwind would work on small projects, or ones where the designer never touches the styling inside the code. But on the other hand, avoiding naming because it’s hard isn’t how I approach organising design, and it doesn’t sound like a good approach to coding either. But I can see how there may be a need to bypass it in projects where there is no designer, or a design system.
