There's a ton of different methods of multicolor printing each with different pros and cons - simplified

* nozzle that mixes from multiple inputs
* multiple hotends on the carriage
* swappable hotends
* single hotend - retracts and switchs to a different filament, few methods here, this is what the AMS and pallete are **

You can do it with multiple heads, the problem is ooze. You'll need to either be able to retract the non-used printhead so that it doesnt ooze onto your print, or be able to swap it mid print. Either way here you'll still need a method to prime it. Some materials may break down in the heat of the hotend too while they sit there unused just baking.

There's some methods that make the blocks smaller, like using the infill as the priming section.
This is a really great README - clearly explained the benefits of the library and anticipated all of my questions about it.
A few weeks ago their mandatory cloud printing service had a bug and caused printers to spontaneously crash in the middle of the night, in many cases doing significant damage to the printer.

Other than that Bambu had a pretty good reputation.
Agreed. I want my builds reproducible. The CI binaries should be bit-for-bit identical to the locally-built ones.
When you say Gitlab "enterprise" is this the on-prem version or something else? They do have SaaS too right?
I like the message, but I feel like the article doesn't support the headline. Instead, it seems to be saying that you should make something that you are passionate about, and in return other people will want it. I have not found that to be true personally, although I would like for it to be true.
I do not doubt the usefulness of written music, as I do not doubt the usefulness of written speech. But you have to walk before you run. Often people play music by eye before they can really hear. Written music is a useful tool, hearing is the essence of music.
> it is revealing that he does not do better with upright faces than inverted faces for face detection and face identity matching," Duchaine said.

> "The absence of an advantage for the face orientation that he's had more experience with suggests that our great sensitivity to upright faces results from both our greater experience with them and an evolved component that makes our visual system better tuned to upright faces than inverted faces."

This seems contradictory, or otherwise confusing from which perspective the orientation is being measured from.

If there's one thing I never felt I properly learned in comp sci, it's proofs. I sucked at them, and I'm grateful I don't need them as part of my job.

That said, are there any good resources that can teach me how to reason through proofs better? Preferably for someone who has a weak mathmatical background? Aside from the Pidgeon Hole theorem, they never clicked with me.

The probably current best solution are "dueling toolheads" or IDEX where you basically have two gantries [1] or toolchangers [2,3].

Both trade-off less waste for substantially added cost and complexity.

“Big” and “small” shift their meaning in context in ways we are aware of, and not aware of.

Things like “almost always”, “nearly guaranteed”, “effectively never” also adjust their meaning relative to context in ways we are not aware of.

There isn’t a solution to different people having different instincts about these numbers, except being aware of the issue, and not trying to project one person’s intuitions as being the “right” intuitions.
Love the X1C as my first 3D printer. They seem to be doing quite a good job and as far as I can tell, their stuff is the best right now.
We're using the Zalando operator. We have our wals and base backups shipped to Azure Storage Blob. Not sure where this S3 only thing comes from. Can you exllain further?
It’s too bad that ever since COVID prime shipping no longer means 2 day shipping - at least in my area. I question why we’re still paying for it as we don’t use Prime Video much either.
I think that's the crux of the problem: we should do this check, and perhaps the first few times we do - but it's a chore every time and infrequent enough that the process has to be rediscovered, with the associated uncertainty that entails (sure I checked - but did I do it properly?)

If it's so important to validate then it shouldn't be left up to a human to choose, it should be mandatory - but the process needs to be straightforward. Why isn't there a built in tool that we can trust to check for us when these alerts happen? Or at least streamline the process and provide certainty
"How do these products compare if I ignore their unique advantages" is not a useful measure.
I heard the same arguments for the Ender printers when they were popular. Best prints ever, incredible detail, etc, etc. At least Ender wasn't actively trying to trap people into their ecosystem.

It won't work though. The clones are coming. Many companies have tried to get the cloud lock-in but it just doesn't make sense to buy in as a user.

Pianists call real-time reading "sight-reading", and it's not what pianists usually focus on. Even the most skilled pianist is probably not going to sight-read a Bach fugue (or be satisfied with the result).

The more common way to read music (at least in terms of the large and marvelous classical piano literature), is as part of a careful process of studying. You read to learn and understand the music, but the reading doesn't need to be real-time (it normally isn't, when learning a piece).

Real-time sight-reading is its own special skill, which you can practice for its own sake. But it's nowhere near as important as the non-real-time learning process mentioned above. I got pretty good at sight-reading when I worked as an accompanist, but I still hate it: It's not how I like to learn a piece. (And the music I find most interesting [like Bach!] can't even really be learned that way).
Their strategy is to make a good printer and allow you to easily use it. Also, the "cloud" thing is not paid or anything its just a way to send files to the printer over the internet and watch the built-in camera from your telephone. You can also just put files on an SD card or whatever and print them.

There are one zillion other companies making super hackable 3D printers or whatever if you want that.

Lately i have been wondering about the weird projects that people make- the “I built a web application framework in brainfuck” or “I built a text based bitmap image editor” or “I loaded an LLM on a Speak’n’Spell” kind of projects (I made up all of those but see similar on HN every day).

I understand passion projects and the article hints that might be the reason, but I just don’t understand why people would spend such enormous amounts of effort on such weird projects.
Yeah it completely blows my mind the amount of technical people that choose apple as their platform. It really is total lock in trash.
Well that is why I asked. I have heard whitewashing used quite a few times in this way, though usually in the context of film or TV. I very well could have just missed it in the moment.

Again, this is why I asked how it was the race-based version of whitewashing rather than immediately going into a debate. I wanted to clarify my understanding and see if I missed anything before jumping down someone's throat, would have been nice to get the same courtesy here.

It comes down to two ways to measure change: absolute (additive) difference and relative (multiplicative) difference.

Additive:

“The price went up 200%”

New price = 100% + 200% = 300%

(1.00 + 2.00 = 3.00)

Multiplicative:

“The price is 300% of the original”

New price = 100% x 300% = 300%

(1.00 x 3.00 = 3.00)
Even into 1982 most people were still renting their phones from the phone company:

Exactly! You had to. 1982 is a very relevant year, the last year before AT&T was broken up. People did want to own their phones, and they wanted choice, and they wanted fun weird phones, or cheap phones, or whatever. Monopoly quashed that.

From 1960 -> 1980 phones barely changed. Compare that to the changes from

This looks really interesting. It implements pretty much the exact subset of geospatial stuff that I care about, in a single C file (an amalgamation that includes its dependencies).

This could make for a really neat SQLite extension, as a much lighter alternative to SpatiaLite.
It's the latter: An "upright face" is a face that has its chin below the forehead. For our eyes, those look like upright faces, but in Claudio's eyes they look like what inverted faces look to us.

So, because Claudio is not better at detecting upright faces than inverted faces, even though most of the faces in his life have been upright, that suggests an evolutionary component.
This is a very interesting printer:

* the toolhead/nozzle quick-change is pretty fantastic and quite ingenius, you change nozzle and heatsink thereby guaranteeing good heat dissipation but the thermistor and heater stay put,

* the MMU seems to be able to handle many more types of spools due to center-mounting as opposed to edge-rolling and they reduced retraction distance substantially.

The noise cancellation seems a bit gimicky just like the LIDAR on the X1C.

The Makerworld integration goes a step further than most other 3D-printing-hub-websites by slicing the models and being to print immediately without having to fuss with a slicer. Should be a lot more beginner-friendly.

It does look like they're taking a page or two from the DJI playbook (not surprising, CEO and others being ex-employees). DJI went from solid drones just a tad above what hoobyists could build, like the early Phantoms, to improving video+link-reliabilty with later phantoms to crazy integration of everything in the newer Mavic and especially Minis that are way beyond hobbyist's possibilities.

I am somewhat doubtful that the exact strategy of tight integration of hardware components will work for 3D printers. After it probably won't matter if one printer is slightly smaller than another.

But they do seem to do more software/hardware integration which could be very welcome for beginners and those not in it for the tinkering, as well as their focus on reliability. Their AMS MMU systems seem to be a step above all others in terms of reliability and ease-of-use.
It’s also consistent with ordering numbers from highest base to lowest:

1023 (1000, 100, 10, 1)

I have been really wanting to get a Bambu Lab printer, but the last time I checked, they didn't support offline printing very well. Keywords: last time I checked. I haven't circled back in the last half year or so.
Yeah a WASM build of this would be fantastic. It looks like it's a very clean C codebase so I expect getting it working in WASM would be relatively straightforward.
Looks helpful. Definitely better than Truecaller

Thank you!
Perfectionism is just the excuse that people tell themselves when they fail and don't want to do the hard work and try again. Nowadays people use this as the standard excuse (along with "i was considered gifted as a child") to explain away their failures. This pernicious habit can destroy one's future and life.

I was responding to:

> it doesn't make it (MSFT) a not-monopoly that its competitors are not able to compete effectively for various reasons.

My assertion is that AAPL could, but won't. The monopoly of MSFT in the gaming sphere is because of a sort of happy coincidence between a massive company willing to support third party hardware (MSFT) and another massive company that depends on not supporting it, to maintain a stranglehold on their market (AAPL) and all the minor players who can't afford to support hardware at scale for a prolonged period of time, to compete with MSFT...even thought a few have for a short time and fell behind or were acquired.
I like the printer. The website UX needs to have the designer smacked. Scroll up, why is it going sideways.
Don't. Less dependency is better.
Because they find it fun? Interesting? I don’t understand how the opposite can be true. “Everything is a product” is a terrible mindset that too many people exhibit, especially those new to tech.

"pay for less ads" is a product in the sense that ad blockers or piehole style network filtering devices are products.

It's not a product when it's implemented by the same company that injects the ads in the first place.
Reason are not obvious to me. Could you elaborate?
I think my recent project https://consciousness.social fits into the category of making something for the pure pleasure of it. But the medium of self-expression is the web, not the platform itself.

It’s like saying that the painting you are splashing color on is a medium of self-expression. I would rather say that painting itself is the medium.

>> Different expressions, conceived by various minds, undergo a form of natural selection, with the surviving expression being the one that resonates most with users. <<

I mean “survival” is a relative term. A painting may not survive, but the ideas encapsulated within that painting may come to inspire others to paint in a particular way. Does that mean that the initial painting survived? In some black and white definition, no. But look closely, and you may see some form of survival.

That’s why I wouldn’t necessarily see the most successful projects as those who attract the most attention. They may be obviously successful, but if something gives you pleasure to do and you “put your entire being” into it, it may be successful in more subtle ways that may not be obvious to you or anyone, really.

A friend of mine recently said that one of the books that I wrote changed the way he looks at the subjects the book was broaching. He asked me how many people I knew that were influenced by the ideas in the book. I replied that if it changed the view of even one person, then it’s enough for me, more than enough.

The most successful projects are those that change lives for the better…even for just one person, even in a non-obvious way. And you’re right, can’t see such things getting made without at least a bit of feeling.

No. The Separation Kernel Protection Profile (SKPP) defines a model for a operating system kernel at EAL6+. So all I am really saying is that safe operating systems are safer than non-safe operating systems. You could also look backwards to the TCSEC and the comparable certified Level A1 systems for other operating systems designed for actual high security work.

You keep calling it a farce, but you keep pointing at EAL4 and lower systems. Yes, those levels are farces, that was the whole point. Those are the levels for the certification of toys where documentation and paperwork is all that is needed, not proper design.

Complaining about the Common Criteria in the context of EAL4 and lower systems is like complaining about tissue paper manufacturers putting their tissue paper through bulletproof vest testing and certifying that it does not stop bullets. Yes, that is pretty stupid, farcical, and probably a waste of time. But no, the test is not stupid. It can test actual bulletproof vests, you just keep seeing stupid waste of time tests proving a useless fact that everybody already knows, the EAL4 quality system sucks and has no place in a serious security organization.
> Farmers markets allow this, at least in my area.

In the area I grew up in, having to pay fees to sell at a farmers market stall with everyone else was already way more overhead than desired.

> Urban Agg is basically always going to (in the US) be vastly more expensive than (still localish but rural) agg.

People growing in what space they have available at no extra cost to them and selling at the same/lower or even higher prices (at whatever volume) than stores (or thru a farmers market) should still be able to accept EBT. People should be able to sell out of their section 8 housing (1937 gov program) and accept EBT.

> I'm really not sure what you're getting at.

Clearly, I'm getting at that people should be able to sell without having a extra physical overhead any kind of store or incorporating (or paying without fees to those who do) and still be able to accept EBT.

If you ever come to Jakarta, you will quickly see what I'm talking about. Can use the same app to buy from a big/small grocery stores as from someone selling out of their corrugated metal roof "house" and have it delivered. Banks finance transaction volume regardless, no gov sponsored channel available to any actor over others in the apps.

It does feel like the market is tighter than normal, but I still get recruiters and cold calls, so companies must be still hiring. ("Ouster", for instance, has open positions. I do not work there. There's some entity https://www.a.team/ which could be something, tho I decided not to follow up, got an odd vibe.)

that's a large assumption, instead of assuming that the boats were already paying taxes as they already existed in the waters before, and the government saw an opportunity to get more tax money from people who couldn't argue otherwise.
Unfortunately, this can't really be done efficiently with how allocation works in Rust. A String is always allocated with alignment 1, but an Arc's control block requires usize alignment. An allocated pointer can't be deallocated with a different alignment than it was allocated with, nor can its alignment be changed when it is reallocated. Thus, the from_raw_parts() idea would be unusable for any types with less than usize alignment.

(And the control block really does need to be aligned, since otherwise we couldn't perform atomic operations on it.)

Computer users may not realize the amount of effort that goes into a "simple" PCB design such as connecting CPUs with DDR RAM.

This youtube video is a practical advanced PCB tutorial that introduces the concept of Delay Matching. The electricity traveling along a pcb trace travels at a finite speed (based on board manufacturing details). DDR RAM is all parallel: meaning the CPU puts the bits on multiple wires and sends the bits down all the wires to communicate with RAM.

"Delay Matching" exists because these bits need to _arrive_ at the RAM at the same time. So, after laying out all the PCBs, the "faster" lines will get lengthened to "slow down" the fast bits, and make sure all the bits arrive at the same time.

Crazy things happen at 500MHz (2 nanoseconds per clock tick) or 1GHz or faster. As such, the faster-and-faster RAM gets, the closer-and-closer these "bit matches" have to be for anything to work at all.

------------

There's a few other issues like controlled impedance and such. But the delay matching lines are really obvious and immediately visible to the naked eye if you've ever inspected a motherboard.

This is also a reason why modern interfaces are favoring "parallel serial" lines, rather than a "parallel interface". Ex: PCIe x16 is 16 parallel lines, but each line is "serial" (that is, the timing doesn't need to match any other lines. Its 1-bit lines run 16 times, each single-bit line at its own speed). This makes life easier in practice for PCB layout.
Awesome, thanks for confirming my thoughts there. Was hoping to prototype a test soon.
