It depends on the accuracy you are trying to achieve, and with what technology.
If you mean FDM, it's absolutely true.
If you mean SLA/MSLA these days, i think you could get there.

On the first - i have an entirely ballscrew + linear rails driven FDM printer with closed loop servos and proper absolute encoders - I got bored and do lots of CNC retrofits/etc, so had lots of parts around. Think of it as insane version of the Pantheon HS30, if you didn't care at all about costs or practicality.

It can position, at speed (IE 300mm/s+), and repeat, the nozzle placement to within 0.0005 inches on all axes, easy.

But even with input shaping/etc, you will not get a better surface finish than CNC, and definitely not one good enough for casting.

Filaments are just too finicky, even with really really good hotends, sensors everywhere to monitor response and optimize, etc.

Now, i did this for giggles, and yeah, i never get misplaced layers, my parts are consistent, etc.

But 0.4mm is still a pretty big feature size, and that's the minimum if i don't want prints to take until the heat death of the sun.

So I could still machine the same thing on my metal mill and achieve castable surface finish, etc, in much less time and effort.
100% agree, but think how long it would take you to install node without all your previous experience!!

Personally I have a list of things to learn that could easily take several lifetimes.
I mean, you still can shut it off, but it’s really pretty unnecessary nowadays. Sleep mode has gotten very reliable and efficient. In deeper power states devices don’t draw much current at all, and still wake up transparently instantly.

People don’t shut their phone down very much, it’s similar with laptops and desktops nowadays.

Thanks for all the info! Great to hear about the availability.

I noticed the other comments mentioned GeForceNow over _ethernet_. What connection speeds do you typically need to play these games over GeforceNow or similar.
One of these days, someone's going to genetically engineer a virus that spreads easily to infect as many people as possible, but stay dormant for a few years while in this phase, then suddenly it'll turn lethal. Someone from the future might use a time machine to try to come back and gain information about the virus, and then even try to stop its spread once he finds the rogue researcher releasing it at airports, but then will tragically find out that you can't change the timeline, even if you can travel back in time.
if the types and field names change, our parsing script should be able to detect that so it should be covered. I was talking about handling the subtle changes that are undetectable by checking field types and names
As a parent, this design looks rather beneficial. I don't need the power button to be easily accessible, but little kids love pressing the button that causes the biggest visual change.

They'll still find this one (it glows, right?), but at least it increases the difficulty a bit.
There are multiple values of type integer? I don’t see why we should truncate the types representing propositions so that they have at most one element each.
Podcast bro.
I’m curious about your definition of the word waste. If a $600 Mac lasts 5 years and still worth $150 and another machine loses all its value in six months, how is Mac a waste?
Sounds like a recipe for neck pain.

A long combined incubation period can counteract the effects of high lethality.

Madagaskar staying safe is not good enough IRL.
Also, the fusion reactors will inevitably have poor volumetric power density, due to limits on power/area through the first wall and the square-cube law.

Engineering studies of stellarators found they tend to be larger and have worse economics than tokamaks.
But this headline is getting clicks because of the initial mortality rate number, which is in ferrets and obviously not applicable to humans since the human who got it had only mild symptoms.

It was a series of overreactions in the media to studies like this one that led me to be skeptical of the news reporting about COVID in its early days. I came around, but a lot of others didn't. Overblown health scare headlines cause real harm for science communication.

Guess I didn't read the parent closely enough. Thought it was asking what the best way to figure out the actual coverage without arbitrarily increasing line width as you zoom out.
Go for it. But I don't see the relevance to the comment you replied to?
I would say the less morality you have and hold onto and or care about the more successful you will be at tech start-ups.
This is probably the cheapest way to get 4x NVMe support, but ~9 months ago I got Minisforum UM780 XTX with two NVMe 4.0 slots and two TB 4.0 ports to use with 3xNVMe drives (one with external TB case).

I've added 96GB of RAM to it and want to move my old dual Xeon behemoth to it, with power consumption at the wall being double CM3588 with 3 4TB drives.

Peeformance is, obviously, incomparable.
Not the traffic itself, just metadata (i.e. netflow).
A single short press locks screen by default. Just a convenient shortcut.
I read this when I was 25 and now I have a fanuc Robodrill in my garage. CNC is quite the bug
>A long combined incubation period can counteract the effects of high lethality.

Reduce, not counteract.

Viruses evolve to spread, not to kill. There just _is_ evolutionary pressure against high lethality.
The bleeding here is subconjunctival hemorrhage, which by itself is not all that rare or serious. You can get it from sneezing too hard. It's happened to me a bunch of times.

I take your point, that the suggestion in that case study is that the virus caused it directly (RTPCR from the conjunctiva tested positive for the virus). He did have a full-blown case of conjunctivitis, though.
M4 Mini vs. M2 Mini
Doing the same thing but faster might just mean you are masturbating more furiously. Show me the money, especially from a CEO.
Or 90 degrees. Although it is smaller by about 36% in width and depth than a Mac Studio, I think that the reasons that prompted my to rotate that 90 degrees counter clockwise would still apply to a Mini for many people.

My Studio is to the left of my monitor stand and a little back. My monitor has crappy speakers so I have external desktop speakers. They are also a little behind the left and right sides of the monitor. The speakers get in the way of reaching the ports on front of the Mac.

With the Mac rotated it can be closer in toward the monitor base, and the ports are then easier to each. Also since being rotated reduces the footprint on my desk there is more room for other things, like a hub I have for a USB hub for my non-C peripherals.
Fair point.

I’m guessing that would complicate blacklist maintenance quite a bit, which is why we aren’t seeing it work that way.

Most of these blacklists (at least initially) were emergency type measures - ‘block these spammers’, then move on with life.

Blacklist maintainers would need to maintain date first seen/date last seen info, and purge/re-add correctly.

Technically, seems like an ‘append only’ type thing is what they’ve been doing for the most part.

As this evolves and the idea that these do need some kind of expiration or we end up with more maintenance headaches becomes more widely known, maybe eh?

Or if there is some kind of legal rules around it.
Reddit is profitable ever, with nearly 100M daily users
Some don’t, some do. A colleagues daughter who is 4 had the realization that chicken is… chickens, which are cute and funny and nice to pet. She won’t eat chicken now.

The colleague keeps chickens for eggs so she’s exposed to them on a daily basis, so maybe that’s where the difference lies. A pig isn’t a common animal kept in a household or even most backyard farms so a child might not have much exposure to them.

Just a thought, dunno.
The power button on the button is annoying. And tbh I always put the mini back as front. Hence I wish they have 2 sides next to each other so we can have all the ports and power button facing me, even if it is an angle.
It also doesn’t seem very realistic that the virus can infect everybody and then evolve to start killing them, and somehow the past infections all get the updated orders to kill, haha. Gameplay concessions I guess.
Interesting. Time to buy a new tv or monitor for programming. Wonder which resolution and size to go. Use 4K 27 for programming and a super wide for my fs2020.

Btw I would use two different glass when I use it as tv or playing fs2020/4 vs when I sit close to use it as programming station.
What evidence is there that “insane Republicans” are the ones spreading ballot boxes? The articles I have read don’t mention any suspects.
I think it was capacitive touch button. There was no physical button movement, and a light came on when touched. I never had issues with mine. I actually still have the cube, including the original speakers, keyboard, and mouse that came with it. I haven't powered it on in years.
I'm a native Chinese speaker. I knew Detexify and used it a lot. This is the first time I see this software. I tried with hand written \succeq, and until its anti-crawler mechanism is triggered, it fails to give the answer. You can argue it is a software with a different purpose (e.g. to convert a piece of content rather than a single symbol), but to me it is not "even better" than detexify.
Love my mac minis... used them since 2006 connected to flat screen TVs (screen resolution set to lowest so it zooms in) and have a wireless mouse as a remote; use Firefox. The entire free un-interuppted Internet from your couch or in your bedroom(s).
It makes me wonder if they're intended to be rack mounted on their sides with half a dozen others.
As a developer who routinely experiments with large OLED panels for programming, a new big monitor has to be:

* Curved (flat is eye strain above ~40 inches)

* 8k.

* Flicker free / PWM free.

* Not glossy.

Otherwise, I'm in!

Ready to retire my fleet of 2560p x 1440p vertical mounts.

Note: Combined these effectively form a curved 5760p x 2650p monitor with vertical bars, heh.
So I'm late for work once. Who cares.
This is super cool! One suggestion for the blog: I would put "re-imagines vector embeddings as database indexes. It's not literally an index but it functions like one to update embeddings as source data gets added, deleted or changed." as a tl/dr at the top.

It wasn't clear to me why this was significantly different than using pg_vector until I read that. That makes the rest of the post (e.g. why this you need the custom methods in a `SELECT`) make a lot more sense in context

Has anyone here tried using CNC machines for gunsmithing as a hobbyist? Is that even feasible? What about 3-D printing metals instead of plastic? To be clear, I know little about either firearms or metal working, but it seems like it would be an interesting engineering challenge for a hobbyist.

Show HN: Quick build- Vote Swapping app for more effective democracy
This weekend I got looped in with this team that was working on a vote swapping initiative. This is where people in swing states (where votes matter more for the electoral college) agree to vote for Kamala, in exchange for people in "safe" blue states voting for their protest vote of choice. So a Free Palestine voter in Pennsylvania, agrees to vote for Harris if, say, 2 Californians agree to vote for Jill Stein (or whatever, I hope this can be a thread about technology and the electorate, not about politics).

The net result is that they can cast a vote against fascism in their home (swing) state It's a weird hack, but it works.

After passing through a google sheets prototyping phase, and a phase where we thought we might fork the UK site (which funnily enough has the domain at swapMYvote.org), we decided our quickest path to scale was to throw something together with Fillout and Airtable.

I'm not a stranger to low-code, but I'm often a high-code guy, so it's been an eye-opening process building something like this on such a short time scale. We had literally a dozen days between the first scalable-ish version, and the election. On one hand, it's incredible to be able to schedule a new automated email, based on complex logic, in a couple minutes - the time it often takes me to deploy a single changeset. On the other hand, the testing tools aren't quite what you need, to make sure you don't break anything important. It also makes a big difference to your scaling speed when you have an outreach team that knows what they're doing. We've gone from zero to oh-no-gmail-wont-let-us-send-more-emails in an incredibly short time.
When are we going to start seeing a database of the details of the people who collect this kind of data and build these kinds of databases?

I'd like to know more about the people who do these things and what motivates them.
tokenminer trojans on m4 without a power off button. i can hear the web3 pyramid scam equivalent sound of cha-ching
Haha I love that movie!
It’s kinda easy to check it though. Ask your friends if they use it, preferably non developer. When I find out my accounting friends and marketing friends are using it for basic analytics/promotion write ups I realized this is being used by non developers already on a regular basis. The use by non tech folks is significant for this . Crypto as a counter example of hype hasn’t lived up to its purported use case as non tech ppl I know only “own” it through an exchange.
Incidences of cancers are increasing (partly due to better screening) and I'm sure it will eventually be linked to pervasive plastic pollution in the food and water just like smoking was eventually linked to lung cancer.

I very much doubt the CEO of TSMC spoke to the NYT about a private meeting they had with a potential customer. Give me a break!

Much more likely they talked about 3-6 fabs, some other person laughed about 36 fabs for podcast guy, someone else overheard that and posted on Weibo. That made it to NYT eventually.
Idle state is probably what, a few watts? Maybe leaving it on 24/7/365 costs you like a few dollars at worst annually or something in even most overpriced energy markets.

I remember doing the math on leaving every single LED light bulb on all day in the house until bedtime, and the costs were so low I had to convince family that it's just poverty mentality and that we don't live in the incandescent age anymore.
Capsule hotels seem pretty decent.

Fully enclosed with a chip vac is good. Chips all over the place is no fun. Especially with coolant.

Don't expect people to precision-cut wood for the frame. The Liteplacer people tried that for their pick and place machine, and most people never got a working machine.
If it needs plates with holes in them, make them in bulk and sell them. Waterjets are good for that. The holes will be where they are supposed to be.

(The Liteplacer was a really good idea - a pick and place machine for assembling prototype PC boards. Camera controlled, with the input parts in partitioned trays rather than reels, it was slow but did the job precisely. The PixiePlacer seems to be the next generation of this. But, as with the Liteplacer, you can't just order the metal parts. You have to make them or have them made. There are commercial machines, of course, but they're for production, feed parts from reels, and are more expensive.)
I will not be extorted by a rectangle lol
if you break the skin, you cannot eat that potato

Be careful out there
I think this is a bit short sighted, but I’m not sure how short. I suspect in the future, code will be something in between what it is today, and a build artifact. Do you have to maintain bytecode?
The eye goes further back than that; the top comment on https://www.reddit.com/r/zeldaconspiracies/comments/c5e8h1/a... has a link to the Link to the Past illustration of Agahnim and the similar eye symbol on his robes. The poster makes the case that they’re not connected lore-wise (I mean, it’s on r/zeldaconspiracies so I imagine there’s a healthy dose of reading a little too much into everything), but in my opinion at least the similarity is strong enough to make a case for an inspiration drawn from the same source that far back.
> I think that's a great idea; having the keyboard power it up.

Again. The power button has been on the keyboard for Mac for many older generations
I don't like devices that sip on power when I'm not home, or asleep. It makes no sense at all. It's not like fetching emails involves connecting to a landline, ring up a dialing device, get... The mac boots faster than my ass gets in the chair. Stuff loads instantly. I turn off the whole desk at the wall at bed time, so all the "mood lights" go off as well. Simple, safe.

I get the convenience of always on, it's just not my jam.
Microsoft appears to be deprecating sleep in favor of Modern Standby, in which the machine draws enough juice to download and install updates. You know, because Windows is a service, and your contract with the network when you get the show is you're going to install the updates. Modern Standby is a low-power variant of S0, the normal "awake", "computer is on" state.

Because what a PC is is defined largely by the needs of Windows, many systems shipping today do not support the deeper power states (S1-S3) at all, just Modern Standby.
Yes, I have literally said multiple times that I have personal experience working one of these jobs. From age 14 to 20 I worked on a dairy milking 800 head of cows, feeding them, scraping their barns and bottle feeding the calves. We did it without air conditioning in 110° heat and humidity, and we did it without heating in -25° cold and snow, because no matter how much I didn't want to work, those cows needed to be milked and fed.

It was tough physical work, and believe it or not most of my coworkers were in fact women, including my own sisters when they were old enough to get a job.
> This is shite design . . . [Stuff] sorted so when an old system plugins in it at least limp mode upgrades

It’s an economic- and risk-based calculation based on security.

You’re trying to get a TWELVE-YEAR OLD system online. Let’s see, since 2012, TLS 1.0 and TLS 1.1 have been officially deprecated (in 2021). In 2024, companies serving TLS 1.1 do not pass certain modern compliance standards. Mountain Lion from 2012 doesn’t support TLS 1.2. Are you arguing that they should leave around a TLS 1.1-based endpoint up, with ciphers that are no longer recommended? And how many CAs can still issue a valid cert trusted by a 12-yr old system?

> [there is zero risk attached]

Community-based Linux distros also offer HTTP (insecure) mirrors. There is also zero risk attached to the mirror serving HTTP. All the risk is on the user side. They don’t care that it’s an exploitable vector. They don’t have a commercial risk/downside. They didn’t sell fleets of old devices with their name on it.

> This is one of the wealthiest corporations on earth

Well this is why. It’s because they spend their money wisely. They decided that supporting OSes over 7 year old (with god knows what unpatched critical bulbs) is not money wisely spent and poses too much risk to their user populace, so they would rather not allow it, rather than support it. They don’t want to train their support on it and they don’t want to allow the possibility of punters getting their old hardware to an older release with open CVEs.

> Are robot-grade servos getting so much cheaper these days?

I was in the market for some servos lately, and e.g. Feetech sells what are basically clones of the popular Korean Dynamixel robotics servos for a lot cheaper.
Apologies for the headline, but I've been tracking H5N1's evolution closely (see my submission history for ongoing coverage).

What makes this notable is the speed and scope of adaptation: In January this was just another bird virus. By March it was in cows, then infected a dairy worker, and now we're seeing it maintain airborne transmission in ferrets while being 100% lethal to them. Yet the human case was mild.

This ties directly to what we're seeing now with 8 poultry workers infected in Washington and 15 dairy workers in California. In less than a year, H5N1 has gone from a bird problem to widespread mammalian spread with increasing human spillover.

When one of the leading researchers calls it 'one of the most pathogenic viruses' he's seen in ferrets, while it remains relatively mild in humans, it's a clear sign of ... something
Worth watching where this Bird Flu thing goes if nothing else. I expect not to hear much about it until after the election though.
I think at that point it’s not really conscious any more? It always takes me a little while to realize my monitor somehow went to 30hz, and that’s why I’m feeling something is off.
I was going to look this up to verify, but realized googling "do they still sell actual human..." probably isn't something I want in my search history. So, I'll just say, as a not-noo-fuzzy-recollection, I'm pretty certain that to this day some people who's bodies are donated to science may end up as actual educational props for medical students. In that light, the above thoughts about wanting/needing to track down this person and contact families seems unnecessary as that person did this intentionally.

That said, I absolutely recall seeing a documentary, in modern day, showing people's bodies used in science exhibits to this day. Their point was that while people had voluntarily donated their body to science, they were mostly unaware that this type of display was something that might happen.
I want to like this but at break even temperatures these things just melt. How about making ship stones from nuclear waste? You could make car engine sized batteries that would effectively last for years if properly shielded and which would provide essentially free power to run a dozen homes.
Oh I didn't know that! Found the setting. Now I really don't need to touch the power button.
Why are these Twitter clones always so resource intensive and finicky? Twitter is just "IRC in reverse", if you take literal descriptions transitive relations in IRC(v2) and moved around nouns, lots of it should apply to Twitter/Bluesky/Mastodon well. RDB gurus can probably recreate lots of APIs as tables on bare MySQL too.

It doesn't make sense to me that such a thing take so much dev and ops cost compared to IRCv2 servers, other than for the fact that modern webdev just so happens to be extremely bloated, especially when extremely competent and high spirited developers are giving up like this.

Are we doomed to keep adding more RAM and more disk and more bandwidth to catch up with ever-growing bloat?
Prospective and retrospective analysis are fundamentally different. It’s easy to point to successes and failures of the past, but that’s not how we predict the concrete future potential of one specific thing.
