Comment Re:But why Unstable Rust? Why so broken? (Score 2) 49

the reality is that you can write very safe C/C++ code if you want to.

You could write safe C too if you want to. You could write safe assembly too if you want to. Unfortunately real world code is replete with errors caused directly by C++ language issues. And even if someone might strive to write safe C++ the compiler doesn't give a damn if it is or not. It might compile because it's safe. It might compile despite being unsafe. Forgot to lock that resource properly before accessing it from two threads? Storing a reference to something deleted elsewhere? LOL C++ doesn't care. Perhaps that is why there is an extremely lucrative after market of static analysis tools because the language sucks.

What Rust offers is the idea that you can achieve perfect memory safety without sacrificing performance. In practice, this is much less useful and bit based on exaggeration, but it makes for an excellent sales story.

It doesn't promise "perfect memory safety". What it does offer is a compiler that strictly enforces ownership and borrowing and will fail with a useful error message rather than allow the error to crash your code at runtime. Any programmer worth their salt would appreciate catching issues early on than suffering the consequences later.

But maybe you love it when your code has some random crash and it takes you hours or days to discover what the cause is especially when it was a pissed off customer who first found it. Ah but you write safe code so that never happens to you and if it never happens to you it must never happen at all right?

They probably don't think it's a mistake but it is. Operating a cloud costs a lot of money and they're pushing a lot of traffic through it with no financial reward. Then on top of that people lose their shit when Bambu tried to improve the security and broke some 3rd party apps. The outrage and the operating expense would be way less if it wasn't the default so less people were affected.

They would have been better off defaulting to LAN, but offering cloud for people who really wanted it. Maybe they could even have charged a $ amount for it, or bundled it up in some kind of subscription service that included some tangible benefits like free / discount filaments & parts, print farm analytics and other stuff.

As for the mobile app, cloud shouldn't be necessary but I assume they thought the phone and printer could be apart on different networks so they used MQTT or some other pub sub bridge to send messages between the printer and app.

It also sounds at best a surefire way to see your reputation and sales tank and at worst, be illegal (and also see your reputation and sales tank). It's corporate suicide and while I realise the company was the target of a buyout, presumably the buyer wants to maximize value, not see it crumble to dust.

So a saner course of action would be: "hey we can't continue to support cloud unless you pay us but we're leave LAN functionality alone". Even better: "hey we can't continue to support cloud unless you pay us, but here are the APIs if you want explore your own choices". Even better: "And we'll put the boot loader keys and sources in escrow just in case we have to shut services down entirely".

You can run Bambu printers in LAN only mode and IMO that should be the default. Bambu made the mistake of forcing WAN and then later they security hardened their APIs & service and broke 3rd party compatibility which angered a lot of people. I don't think its unreasonable to protect their cloud service but it was unreasonable not provide 3rd party APIs, or make cloud the default to begin with. The only thing cloud adds is the mobile app and some network flexibility (e.g. printer and computer on separate networks). But if you don't need that you're better off switching the printer to LAN mode.

Exactly. Anker's printer was originally the same price as an A1 so who's going to take the plunge on an Anker when an A1 works exceptionally well and has after market support? That said, Anker's printer is on firesale right now, so maybe it is worth a dip for someone who needs a cheap backup printer.

I expect most people aren't even interested in making money from their printer, they have one as a hobby in its own right or to support another hobby. I use mine for esoteric reasons - designing & printing replacement parts for things that break around the house - containers, hooks, clips etc. Random stuff. I don't see it as an "investment" but something to occupy my time and learn things.

It may not be mainstream but it's not a small niche either. Lots of individuals, schools, universities, businesses have 3d printers, and there are many, many popular brands of SLA/FDM printers for the home market and beyond. And there are a multitude of brands.

The issue for Anker or any other company trying to enter the market is that you'd have to produce an *exceptional* printer to stand out from all those brands. That's the reason Bambulabs is ascendant right now because their printer offered a lot of bang per buck in a reliable package and it generated buzz. Anker's printer offerings were fine but they were just another bed slinger in a crowded market. If the choice is a Bambu A1 for $399 or a Anker M5C for $399 then the Bambu wins. I note that Anker are on a firesale since this announcement so perhaps this is a good time to pick it up a cheap printer, but ordinarily... not so much.

It is just a matter of infrastructure and legislation as you say. If Norway (a country with hard winters, especially up north) can manage to go all electric, anywhere else can too. Besides which the vast majority of people do not live in remote icy wildernesses so it's kind of moot to worry an EV *only* has 250 miles (which is typical for most mid size EVs these days), or it might drop to 180 miles on a cold day because even if it did it's still more than sufficient for what most people need in their lives.

And if people really do need better range then battery tech is only improving - there are cars right now with 400+ mile range and plenty more in the 300+ mile segment. As battery energy density increases and new chemistries appear I expect that EVs will diversify even more to provide what people need from their cars.

The average motorist is doing less than 40 miles for their daily drive and Europe its 30 or less. So most people, the majority of people could comfortably use their car and go days between charges, perhaps all week. And for longer trips, sufficient fast chargers along the route suffice.

Comment Shades of Toyota FUD (Score 1) 180

"According to Markus Schafer, the automaker's head of development, the first Mercedes EVs powered by solid-state batteries could be here by 2030. "

Toyota has been doing this bullshit for years. "Oh solid state is just around the corner and we're testing it so better hold off buying that EV you're after because it'll be obsolete soon *wink* *wink*". solid state battery.

Even if there were a viable, production ready, solid state battery announced today it would take years for that to translate into actual production because an entire supply line, infrastructure and factory would have to be built to manufacture the thing.
