I also found it super easy. The most difficult part for me was finding a data capable MicroUSB cable to connect the Pi to my printer. Most of mine were only for charging. I used an old RPi 3 and used the OctoPrint SD image. After that, everything just worked. It even worked with my USB webcam instead of the default RPi camera.

This was connected to a Creality Ender 3.

It might be more difficult to install as a package as opposed to using a pre-made RPi image, but it should still be pretty straightforward.

There's always a bit of the opposite effect too. If supply of something is extremely low, then people eventually stop looking for it. People might want the object, but they might not express that desire if the supply is next to non-existent.
I have a lot of "smart" devices and they aren't connected to the internet. Home assistant and Zigbee2mqtt is amazing and it's all local. The only internet "smart" devices I have are a ecobee thermostat and a water monitoring system, both are in their own VLAN with only access to the internet. My thermostat can be controlled manually if internet is out.

I own a LG 4K OLED TV, I put it in the same VLAN add above and block all requests to the internet. Instead I use an nvidia shield for streaming tv and movies.
That's because he lacks empathy. (Only someone lacking empathy would accuse someone who accused someone else of lacking empathy of doing so due to lack of empathy.)

This is a rare instance where I actually think both you and rayiner (both otherwise awesome HN users) are wrong.

Your characterization of Trump vs Biden/Obama is refuted by the AP themselves: https://apnews.com/article/election-2020-democratic-national...

> WASHINGTON (AP) — Michelle Obama assailed President Donald Trump on Monday for ripping migrant children from their parents and throwing them into cages, picking up on a frequent and distorted point made widely by Democrats.

> THE FACTS: The reference to cages is misleading and a matter that Democrats have persistently distorted.

Rayiner's characterization that the AP has never provided "context" for what Trump did is wrong per the above link, which could actually be found in the original link cited.
Pipe It Platforms, Funding, and the Future
Well it goes onto a raspberry pi which acts as a web server, that connects to the printer. You then visit the octoprint website interface to manage connected printers. That's handy because I can do it from my phone or computer so long as I am on the wifi, and you can in theory reach it remotely while out of the house if you set up your network to allow that.
You've obviously never tried GMail in Firefox, though that's probably intentional.
Just don’t connect your tv to the internet. Easy peasy.
I flick lights on and off as I enter a room, which I agree, might use 1/8th of a second each time, say 2 seconds a day. And the light switches are well over two decades old. I have given them 0 thought over those years, and don't expect I will for a few more decades.

A simple $25 programmable thermostat keeps the temperatures moderated. It may use a bit more energy if I'm running a different schedule than usual, but again - decades old, works fine. Car AC, again - works fine, turns on when I turn on the car. My blinds go up and down when I want them to, which has nothing to do with my schedule.

Nothing you've listed (or anyone else who talks about smart homes) is even a positive to me, let alone a time saver.

Sure, gliding helped to avoid many catastrophes (Gimli Glider, Hudson miracle, etc.) but the thing is - does it make sense for a rocketship ? On a point to point flight you are going to land (or impact) somewhere and you need a couple working engines to land safely, the same as you need working control systems to glide to an airport.

Still, Starship does not really need an airport for emergency landing - anything reasonably level will very quickly become a landing pad once the raptors get going for landing.

Also as for wings - those seem very complex to me on a modern airliner - flaps, spoilers, ailerons, wingless, integral fuel tanks, etc. In comparison to that starship is a lightweight water tower with a couple metal barn doors attached - much simpler structure with far less moving parts.

Nuclear is one notch above dead, though I'm sure it won't officially die for another few decades. As a former proponent it's hard to argue against the significant advances made by renewables over the past few years. Sure, nuclear makes for a better baseline load, but the regulatory and safety requires of nuclear make the economics difficult, almost easier to just build overcapacity into the renewable generation.
replication is still happening in the lower cellular/molecular scales, even when the aggregate organismal level isn't reproducing that pattern. People who take these definitions very seriously aren't implying that elderly people aren't still alive :)
You have to know the offset though. And if it is with multiple people you might even have multiple offsets. There's nothing easier about offsets over differing work times
The other guy is right - if you have a network outage your appliances revert to “normal” behavior.

But even after that, it’s not just about the time saved. It’s an increased amount of convenience in day to day life. I mentioned this in another comment, but you definitely feel a sort of reduction in cognitive load when your desired home state can be triggered with a spoken word.
The thinness really prevents decent speakers being part of the tv itself. You're essentially getting mobile device level speakers on a 40"+ screen. Then, they aren't even facing you. As much as I'd prefer a dumb TV, I'd also prefer a mute TV. Don't waste effort/money on putting something that nobody is seriously going to use.
No app is a feature for me. It's a fairly big ask for a free open source project to navigate the Google Play and Apple stores too, I feel app stores have no place in the open source ecosystem. I wouldn't wish that headache on any project trying to provide something for free.
They had to buy some IPv4 addresses, which they use for CGNAT; they put a lot more customers per IP than T-Mobile US does though. Then they push everyone they partner with hard to do IPv6. And it makes sense too, if your customers are on Jio, things will work better if you can do IPv6 to keep them off CGNAT.

I just hope people don't fall into the trap of believing every 10x engineer is just a symptom of dysfunction.

There are some truly remarkable people in this line of work and there exist 10x engineers that are just extremely smart, extremely hardworking, and it doesn't come at the expense of others. You'll recognize it when you see it -- if you're lucky enough. I feel blessed to have run into 10x people, because I really needed to be humbled. You have to work hard.
You will be surprised by how much inefficiency is involved in modern Procurement and Supply Chain by Fortune Global 2000. Apple took the Toyota JIT system and fine grained to a point that exceeded Toyota themselves. But since Apple is a technology / lifestyle / whatever company no one look at them from a manufacturing / operation or Supply Chain perspective. And so they didn't learn. And even if they did, I am coming close to the conclusion they wont understand it anyway.

By way of example: WaPo today, reporting on the peak of children in HHS custody under Biden, comparing unfavorably to Trump, leaves out that those children are confined for an average of 4.5 days before being transferred to family members and sponsors. During Trump's family separation program, that number was 154 days, and in some cases for over a year.

Huh really? Didn't know nuclear waste contains botox!

Sorry for the glib answer, but this is the biggest problem with anti-nuclear sentiments. Phrases like "most toxic substance" or "perpetual risks" doesn't mean much unless you quantify exactly how much of this toxic substance we're talking about. Botox is 320,000 times more toxic than plutonium (according to Wikipedia), and we inject it under our skin.

I’m talking more about general smart appliances than smart TVs. I don’t connect my smart TV to the internet, that’s the job of the Apple TV or Nvidia Shield.
There's been a concerted campaign against nuclear energy since its conception that has been incredibly successful and pervades even tech-literate forums such as this one. I think people like me are just very frustrated that negativity about nuclear energy abounds, when there isn't any basis in fact for it and it's pretty much our only hope to make meaningful progress towards limiting climate change.

Think of it as akin to anti-maskers. Of course you're going to get a lot of push back. Not only is it wrong, it's an ideology that kills people.

Oh, and to answer your question:

"The U.S. generates about 2,000 metric tons of used fuel each year

This number may sound like a lot, but it’s actually quite small. In fact, the U.S. has produced roughly 83,000 metrics tons of used fuel since the 1950s—and all of it could fit on a single football field at a depth of less than 10 yards." [1]

[1] https://www.energy.gov/ne/articles/5-fast-facts-about-spent-...
To answer my own question:

Assuming 2KWh / mile average consumption[1], an EV semi powertrain would be pulling ~120KW continuously from the battery. Even at 90-95% efficiency, there will be 6-12KW of waste heat available in the powertrain, more than enough to heat the cabin in cold weather. Modern EVs actually do scavenge waste heat from the battery and motors for cabin heating[2], unlike the EVs tested in the cited article.

But even without using the available waste heat, a 6KW resistive cabin heater would only use 18KWh over a 3 hour drive. For a cheap passenger EV, this could be 20-40% of the battery, but for a semi with 500 miles of range, 18KWh would only be 1-3% of the battery.

Put more succinctly, the battery in an EV semi would be 5-10x larger than the battery in a passenger EV, but the energy required to heat the cabin will be roughly the same. So the effect of cabin heating on range loss would be 5-10x less on a EV semi than a passenger EV.

I would remove this line from your post: "plus the batteries lose > 40% of their range in cold weather" because I don't think that claim is supported by any source, or by basic logic and math, in the context of a semi truck.

IMO TMR is the best font for any kind of pure technical documentation. To me a document written in TNR feels like pure and useful form of information without trying to sell something or force some opinion on me.
I have connections with the academic GC community. I gave an invited talk at ISMM 2012. I guarantee that they will not agree "Rust is a garbage-collected language".

FWIW Wikipedia describes "garbage collection" as "a form of automatic memory management" and goes on to say "Other similar techniques include stack allocation, region inference, memory ownership ..." so whoever wrote that doesn't agree that all forms of automatic reclamation are garbage collection.

I prefer to avoid arguing about the meaning of words but it's not good to sow confusion.

> Are the several multi-100-kloc ats compilers out there not real-world enough?

Yes, projects written by the creators of the language are not enough.

> If not then, on the topic of proof languages, ada/spark and isabelle/hol had proven themselves long before rust.

Before Rust, Ada/SPARK didn't support dynamic deallocation. See https://www.adacore.com/uploads/techPapers/Safe-Dynamic-Memo..., which cites Rust.

SeL4 required 200K lines of Isabelle/HOL proofs to verify 7.5K lines of C; that approach simply doesn't scale.
I was just looking up some recipes the other day and my goodness, does this website feel like a breath of fresh air.

Today's web just utterly buries even the simplest content underneath a mountain of shit, whether it's ads or fancy banners or a long-winded speech about god-knows-what before getting to the point.

Kudos to whoever made this.
I imagine for many (most?) people, it's not that they want the "internet connected garbage"; it's that they want the big 4k TV and they're wiling to put up with the garbage that comes with it.

'radiation did not damage health of local people' is interesting language here.

"As of the end of December 2015, 51 people were diagnosed with malignant or suspected malignant thyroid cancer in the second examina-tion conducted by Fukushima Prefecture.... As of the end of June 2015, 113 people were diagnosed with malignant or suspected malignant thyroid cancer. Of these, 99 people underwent surgery.... the Fukushima Prefectural Citizens Health Survey Committee has not recognized these thyroid cancer cases as the result of the Fukushima accident; the Committee’s reasoning is... that some of the subjects may have been over-diagnosed."[0]

[0] Katsuta T. (2019).'The Reality after Fukushima in Japan - Actual Damage to Local People'. https://web.archive.org/web/20200326151713/https://link.spri...

Some of the subjects may have been over-diagnosed. Should medicine not err on the side of caution? Given the results near Chernobyl?

At any rate, there were certainly deaths as a result of the plant's failure. About 2000 people died as a consequence of disaster-related evacuation measures. Whether the radiation was directly responsible or not, the damage to the plant and very real dangers of potential exposure undeniably led to those deaths. Is the UN saying that evacuating tens of thousands was an over-reaction? Was the extreme threat posed by the highly unstable condition of Unit 4 "over-diagnosed" by most western experts?

The ongoing spin on this topic is disgusting. March of FUD.
The prefab baths (at least those in Japanese hostels) are superb! Basically no seams where dirt could accumulate and mold grow, robust ergonomic and well thought out furnishings, splashproof doors and lighting.

European accommodations of similar price category have much worse & more dirty bath facilities in comparison.
I wasn't suggesting that journalists wrote their own headlines, although for smaller publications it was more likely to be the case. I worked at a newspaper in a 50k city and journalists gave suggestions with their copy.

My point, rather, was that headlines slip past the journalistic barriers applied to copy. Often the people on the desk are making a headline fit at 11:45 pm or later and have no real oversight.
ansible can be used to build container images in an idempotent way. And ansible is greatat creating deployment logic among other things. Where puppet , chef et al. are primarily for automating a direct machine, Ansible is a general purpose automation framework. Terraform is definitely better at provisioning cloud resources, but Ansible is much better at automating pretty much anything else that you could think of.
It's not a real problem. There really isn't that much high-level nuclear waste and we have a problem with classifying too many things as high-level waste in the US.

For the little actual high-level waste that is produced it's a pretty viable medium-term solution just to leave it onsite at the power plant.

The long-term solution is obvious: you bury it in a deep unmarked hole, duh.

This has been done [1].

Say it with me, there is no nuclear waste problem.

Maybe I'm in a minority, because everyone always hoots and hollers about how they hate modern recipe web sites -- and I get it, 6 pages of memories of trips to grandma or whatever is ridiculous -- but I can't see myself ever using a plain-text recipe with no clue as to who the author is and no reason to suspect that they know what they're talking about. At that point I would probably go to SimplyRecipes, where at least recipes are voted on.

The sites that keep me are the ones that don't blather on about grandmas but do subtly give me some reason for why I should trust them, they explain that this technique makes the most sense, they describe how they've tweaked it from this cookbook or whatever. I also read the comments. In the end, though, my pre-existing trust of the site and author makes the most difference.
It was made by a linux youtuber who occasionally (often) complains about bloat, the the point that 'bloat' became an overused meme by commenters on his channel. Looks like he practices what he preaches!
The advice to eschew iodized salt in favor of kosher salt is dangerous. Iodo-deficiency is a significant number of IQ points, and in the first world, iodized salt costs the same as non-iodized. It helps thyroid function too, please do not go out of your way to avoid free iodine in your diet!
Ask HN: How do you interview and evaluate candidates at a startup?
I'm curious to learn what's your process to interview and evaluate candidates at an early stage startup?

Do you have any methodical process to make sure your decisions are as accurate as possible? is it helpful? Do you use any tools in the process?

Context:
I'm thinking about building a lightweight tool that will help startups introduce some research-driven construct to their process.

The goal of this tool is to help with 20% of the process that account for 80% of the gain in terms of making sound, unbiased hiring decisions. What do you think about that?

I'd personally define it more widely, as I think that's more aligned with reality. It's much more of a gradient than we usually take it for, imho

One thing that's very striking to me is the anti-nuclear folks have managed to strand something like 400,000 TONS of nuclear waste in temporary facilities. These are often surprisingly high risk (on large time scales) with many other negatives. There is obviously a lot less high level waste, but the point generally holds.

Addressing the nuclear waste storage issue has value. Credible science I've seen suggests current approaches are poor relative to almost all other options.

I also like repossessing, and other countries do this (most spent US fuel has actually a huge amount of remaining life). US fuel is generally a solid that is more controllable, repossessing can create some high level by products that require vitrification as I understand it and the US doesn't have that as well established.

There are folks looking at ultra deep burial, below water tables in rock stable for millions of years. That's also interesting.

We are arguably facing a relatively pressing current issue with global warming. Nuclear does not have a lot of GHG emissions relatively. It seems we should be spending reasonable sums at least on research and perhaps very small scale demonstrator plants and waste options to see if anything can be proven out.
One advantage of that kind of control is that your code does not depend of the implementation of any abstraction (except the operating system if any?) since everything is written "in stone".

I also think it makes a great learning tool, mainly to understand:

- how a GC or memory management is/should be implemented
- what pain points they solve (or: why they are important)

When you don't have to think about the abstractions but only your code, it prevents the student from being confused about what happens when.

But I would not use it in production, just like you said, because in production, I want to maintain as little code as possible, and delegate the complexity to other better tools/people.
On the contrary, code quality sucks now because there's not enough talented programmers to go around. So many smart, quick witted kids are getting diverted into other professions. What if the total number of capable programmers doubled with the same amount of work? There's plenty of developers today who would be considered flat out incompetent if you held them to standards for any other industry. At the very least there's not enough qualified individuals on the job market to force those people out yet.
