This is a really cool idea. I think the limitations are that you can only make filament rolls that are small enough to fit on your bed, and the precision with which the colours match the intended part depends on how much oozes out when you're priming the nozzle.

I noticed that some of the parts shown in the video appear to have a wipe tower next to them. Presumably this is because the G-code was generated with Cura or similar, but given that the filament is one continuous piece with colour changes in exactly the right places, it seems like you could skip the wipe tower? Or maybe it's better to keep the wipe tower because it reduces the precision required in priming the nozzle?
I appreciate the nuanced response and I also believe you're also coming from a place of compassion here too.

I agree to an extent, but I think it is too easy to take a nasty turn in this age of information overload. It's very easy to cherry pick salacious details and run with them, knowing that people will take it at face value.

I'm absolutely not accusing anyone here of doing that, and in part I'm not responding to the parent in as much as I'm also venting my exasperation about how we talk about people on the internet these days.

Even if Connery did publicly retract or apologise, for example, how many people would try to seek that out if all they saw was the original video in isolation? Once a criminal, always a criminal? Or can we imagine that people may change even without making a public song and dance about it?

These are the questions I ask myself.
There are a combination of different things.

Firstly, better capacity factor for onshore wind, offshore wind becoming cost competitive and the emergence of floating offshore wind reduce a bit the intermittence, then the cost of managing it

Secondly renewable is becoming so cheap that installing more than peak demand and setting up curtailment is cost competitive and reduces the intermittence and the cost of managing it. There are also solar project not optimizing for maximum production, but for producing when needed.

Solar-plus-storage is becoming more and more common for new project, with cost falling. Generally all the batteries cost are in free fall while we are just at the beginning of the market expansion: massive economy of scale are on the way, with proven technologies

More electrical storage are coming... Flow batteries, pumped hydro on isolated reservoir (eg Gordon Butte), liquid air, underground compressed air, stacked blocs, hydrogen... And there are many other tech in the lab at the same level development of SMR. Of course all the promising tech wont be a success or be cost competitive, but with SMR you bet on one tech, here you bet on more than a dozen tech.

Virtual Power plant and Demand-response project and market are blooming (and that is a start)...

This last point open a wider market for thermal storage, with existing cheap and mature technologies, and many developing project (relatively low tech) like inter seasonal heat or cold storage

Yes, that was a concern back in March. Back in March, when we had very little understanding of transmission and when hospitals were facing dire mask shortages. What has the surgeon general said since then?

Are people on HN actually too stupid to learn how to properly wear a mask in 8 months time? I don't believe that. I think that each of us is smart enough to do that research and train ourselves.
This is only anecdotal, but I grew up in a permanent daylight savings time north of 60°. I remember being a teenager and having a really hard time waking up 3 or 4 hours before sunrise.

In the past few years health experts from this country have advised a move from the permanent daylight savings to standard time, citing health benefits of good night sleep, particularly for teenagers. The polling shows quite some support for it (over 50% if I remember correctly). However the government decided against the move for arbitrary reasons despite all this.
I really like that distinction, relating imperative/FP tradeoffs to the classic space/time tradeoff. I'd also point out that betting on space getting cheaper over time seems like a better bet than betting on time getting cheaper :)

How long until Tesla (or any manufacturer) remotely disables the ignition on all used cars until the new owner pays them to turn it back on.

Its only fair. After all, the new owner just bought a hunk of metal from the previous owner. They still need to purchase a license for features like starting the car.

Society's job is to weigh this cost with all the others +/- and decide what to do.
> Development boards are typically more expensive

That's not what I've experienced: Arduino's are cheaper, Teensys are cheaper, Adafruit boards are cheaper, many others too.

And that's just regular retail prices at e.g. Mouser, or even the official websites — without even getting into the super-cheap Chinese stuff on AliExpress/etc.

— Why the downvotes? IDK, maybe you meant more powerful boards than those?

Sean Connery Dies
Kids and teens need a lot more sleep, perhaps 2+ hours more than adults. I recall many slow mornings being harassed by my mom to get up already, it's time to go. Without a helpful mother, oof, I would have missed a lot more days of school.
That's exactly why Bitcoin is interesting. It is currently being accepted as having it's own value, just like gold. It's an experiment that seems to be working.

Cash or collectibles don't have the same monetary properties as bitcoin or gold. Most importantly, they can be created from thin air.
Russian here. Unfortunately, our technological success was mostly limited to military production. And even there, quite a lot of technological processes and templates were simply stolen by our spies (starting from our nuclear weapons program). Granted, Americans used to do that too... USSR used to have a lot of independent discoveries and inventions. But nearly all of them were targeted to the military; Soviet cars, television sets, washing machines etc. were all truly awful.
I am reasonably confident a large percentage of Tesla's antics are blatantly illegal, but Tesla owners are still too few for someone to have actually gotten fed up with them enough to start suing them.

Refusing to activate a car you have the legal title to in any scenario is almost certainly illegal, whether you "salvaged" it or not, for instance. Some of the ways they restrict your car they already sold you, the way they use your cars sensors to collect data for their use, even if those sensors are disabled for the owners' use (Autopilot not purchased), etc. are probably one good lawsuit away from being thrown out.
Wait ... but ... why? (in jest)

I understand why, though some of us think of decaf "coffee", much the same way others view white "chocolate". At some point, the thing you modified it to be, isn't representative of the original thing. IMO, it should not be called coffee or chocolate, even with a descriptive adjective up front.

This is a minor nit to pick, but still, for those of us with a strong love of (addition to) coffee (or chocolate), its an important distinction.
Timezones were a Bad Idea™. Swatch tried to push Swatch Internet Time [^1] but it could never take of with the hubris of the Swatch brand and repartitioning the day into 1000 "beats". Base 2, 8, 64 or 256 would have been more useful, but 60 divides evenly into 2, 3, 4, 5, 6, 10, 12, 15, 20, 30.

Perhaps an Internet Time Zone (ITZ), Earth Time Zone (ETZ) or Digital Time Zone (DTZ) could have gotten more traction?

Please can we abolish timezones. I am totally fine describing my working hours as 03:00–11:00. We have computers now, we can update text in contracts, time-based rules and laws.

My post addresses this at the start, which is why I construed the analogy as such to reflect the editor's requests.

Greenwald's article is fine. But I don't think the editorial followups are unprecedented or objectionable from the perspective of your typical run of the mill engineering practices.

If Greenwald is uncomfortable with collaborating with editors, he may return to his life as an independent journalist, as he has done so.

You mean a mask which filters both on inhale and exhale? N95 masks do a decent job of that, although I'd guess there's still some leakage on exhale (not designed for that). N95s are still sold out in my area, so I got some KN95 which I use. The CDC tested some of them for effectiveness, many of them got pretty high marks: https://www.cdc.gov/niosh/npptl/respirators/testing/NonNIOSH...
"Disposable" medical masks cost pennies to make, can be worn for multiple days, and are highly effective. In an environment where some folks refuse or can't mask, they are the most effective way for people to keep themselves safe.

By the way, I don't make or sell masks. I'm just interested in keeping people out of the hospital and my friends/family safe.

Its definitely going to be real world drivers who opt in at their own risk. My understanding is that Tesla views its large number of cars as a test ground to get to level 5 autonomy. It will slowly roll out more and more autonomous functionality and incrementally get there. You simply cannot solve the tail end of issues with test driving alone.
> If you don’t want this business model, don’t buy a Tesla.

I don't want this business model, so I haven't bought an EV, since basically all the EV manufacturers have adopted it.

You need a certain diameter of the pressure hull in order to accommodate the length of the missiles and their launch tubes. Also a factor - the range of the missile. Want a longer range? You'll need more fuel and the missile gets longer. Which means you need a bigger sub.
Just to play a bit of a devil's advocate here, a lot of the same questions have "bedeviled" (and I mean that a little sarcastically) securities lawyers in corporate restructuring cases over the last century. And by "bedeviled" I mean not really. It's a bit of a leaky analogy that you really have to squint at to make work, but the concepts of subordination for bonds and liquidation preference for equities can roughly be analogized how to how forks achieve consensus and resolve disputes. Which is to say, the fork that the network operators (even if that's a distributed, automated consensus) agree to use is almost tautologically is the one that wins. Just like in real life with courts.

That's not to say your comment doesn't have some merit -- I think a lot of blockchain proponents are also of the type to believe that manual edge case dispute resolution (otherwise known as "the law") can be completely removed from blockchain use cases. And of course that is a bit farfetched. But is that a bad goal to strive for? I don't know, I think it would be kind of neat to have some sort of algorithmic countervailing force balancing against an otherwise unstoppable proliferation of bureaucracy, corruption and regulatory capture that I see almost everywhere in the world. Is that such a bad thing?
I'm honestly not sure it is sarcasm at this point... The entire situation is approaching Poe's law for me.
Indeed. They had extensive surveillance and sabotage networks all throughout the world. Simple because it was easier (and cheaper) to just steal it than develop it domestically. With the soviet demise, that apparatus hasn't gone away. Russians and Chinese still work off that approach.
Aside from PHP itself, the headline drew my attention:

> 2020 was a good year to be an entry-level candidate for technology jobs

Not sure what's others' experience here, but from what I hear in various markets (mostly within EU) is that fresh grads generally struggle this year, no matter the technology.

Companies put hiring on hold and if they resume it's primarily for more critical roles (read: senior positions); it's harder to get a job or even internship as a junior developer.

Am I in some kind of negative bubble?

We manage a lot of social ads for brand in Germany, which is obviously the biggest EU market. It‘s mostly very slow adoption rate of new channels, so it‘s mostly lag. Additionally FB Sales internationally has been mostly horrible, so I think they just did a horrible job in their ad sales in Europe. OF course some parts of it like the split between digital and other channels is not only FB responsibility, but still... I think they are just horrible in this. I just had a client who invests Millions with Google every year and nothing with FB, there might be a good argument for let‘s say 60% Google or 90% Google but there is nor argument for 100%. So lag, less availability marketing budget on total and a stupid sales process.

I was curious because arguably behaving differently according to their gender (i.e. not hitting a woman back) is what would be sexist, (albeit a widely accepted form) but as it is it ('my word is final or I hit you'?) just seems bad regardless of whether the other person's a man or a woman...
This reliance on OS updates is a really big problem for devices that rarely receive any, like Android phones. As an Android developer in Russia who worked on a very popular app when our government changed timezones, and then did it once again a year later, I wasn't thrilled. People started doing the silliest thing: instead of picking a timezone with the correct offset, they just set the time to read correctly, thus shifting the unixtime by an hour. They then proceeded to complain that my app doesn't show relative dates correctly (I just posted it but it says hour ago). Had to add an ugly workaround involving getting the known-correct current unixtime from the server and using the offset from that in all my time calculations. Fun times.

And no, you can't update the timezone database yourself. It resides on the system partition which requires root or at least an unlocked bootloader to mount as writable.
Bitcoin does not have value of its own. What can you do with a Bitcoin as printed code or eWallet without functioning Bitcoin economy?

It is fiat tied to used value not means to gain value.

On the other hand, you can manufacture useful things from metals, including precious metals.
Heck, even old school non-precious metal coins have some of that value.

People also used to wake up at 1, stay awake for a couple hours, and then go back to sleep.

https://www.sciencealert.com/humans-used-to-sleep-in-two-shi...
I don't know what they debunked, but I do know that if I follow my natural sleeping rhythm, the wake-up time keeps advancing by an hour a day. If I wake up an hour earlier to compensate for this, it's really hard and unpleasant to do and I feel like shit afterwards.

So what I converged to is sleeping 2 hours less on weekdays and then sleep in on the weekends. This is marginally better, but still Fridays aren't very nice.
This appears to be the Instructables post that the authors briefly mention as "inspiration": https://www.instructables.com/DIY-Rainbow-3D-Printing-Filame...
Neat idea. Still needs a purge block of course, but I wonder if it could be altered to extrude it into another "purge filament" which could be used again as scratch filament.

I guess there might be a limit on the number of times material can be extruded from a hot end before it starts to degrade?
humans self selecting for a lack of genetic diversity (as we do) creates a monocrop of humans with all the susceptibility that entails.

Perhaps a real geneticist will chime in, but I seem to recall we can find more genetic diversity within a family of another species say chimps or dogs than we do across the entire human species. We thought our lack of diversity was due to some "bottleneck" event where the global human population dropped to around 10K. But then we sequenced neanderthal and had to re adjust that to many repeated bottle necks each decreasing the chance of being it being a correct hyposisis as just one bottleneck is unproven.
A different explanation is there were no global bottlenecks just the multitude of day to day local choices we have been making for a long time.

It is similar to the legend that says the Germans supplied the red ink for the bright army pants of French soldiers on the field in 1914 « for a good price » (you bet!), although I think this one is rather a legend, as it is true that French costumes were too fancy for war, I think the traditional red pants were not in widespread application at the time.
