Oh hi again Kragen, I didn't notice it was you.

This is the specific model (EM-SMart Nova 18W):

https://www.em-smart.com/EM-Smart-Nova.html

I don't have a depth gauge but I would guess 0.1 to 0.2mm. It's with 10 passes, which takes about 8 minutes with a complicated pattern like the crest on the coin (stainless steel, about 20mm in diameter).

It doesn't work on brass or raw (not anodized) aluminum, not because of reflectivity but because they are thermally very conductive and don't heat up locally like steel or titanium would. The dog tags are mirror-polished and very reflective, but they engrave beautifully. On anodized aluminum, the laser just strips the anodizing, revealing the raw almunum underneath.

Repeatability is excellent on the galvo, otherwise it would not yield good results with multiple passes. I can't give a dpi rating because it is intrincally a vector machine, but here is a pic with a calibrated microscope showing a 1mm square grid superimposed:

https://majid.info/images/reddit/laser_engraving.jpg

Their rating is 0.01mm, which is probably optimistic. In any case, you can see the sparks the metal makes as it is ablated by the laser, that process is inherently a bit messy, just like you can't compare a laser printer's dpi with an inkjet's because the ink drops splatter:

https://majid.info/images/print_quality.jpeg

The working area is fairly small, about 20cm x 20cm x 10cm, pretty common for galvo heads. The limiting factor is the optics since the laser head itself is stationary and the lens needs to focus on the engraving plane. You focus by raising or lowering the head on a vertical rail using a knob. Some fancier models have motorized Z axes and autofocus cameras.

I've never tried on razor blades, I would assume it would punch through. It's likely thermal warping would yield unusable results, however.

No idea what the cost to run is, I doubt it's more than a couple hundred watts. The main cost is the laser, I paid $2000 for it on Black Friday special plus about $500 for the enclosure.

The brand of the engraver doesn't really matter, they are all assembled using the same lasers, galvos and lenses, just like most PCs are made from the same few components no matter whose brand sits on the faceplate, but getting support will be important. I had to fix mine because the red preview laser burned out. It's not too hard if you have any experience with computers and electronics (no soldering needed) but still a bit disconcerting.

The EZCAD 1.x software (Windows-only) is abysmal. I would strongly recommend getting the Mac-only Lightburn software instead if your laser is compatible (mine claimed to be but didn't in practice, and I had no interest in debugging this).
prokube.ai | Platform Engineers | Northern Germany (Hamburg or Bremen) | Full-time | ONSITE (or hybrid) | https://prokube.ai/ https://www.justadd.ai/en/

We are building an integrated MLOps platform based on Kubernetes, Kubeflow, GitLab and many more best-of-breed Open Source solutions, running anywhere our customers need it to (on-premises, in the cloud, or in a corporate data center, possibly air-gapped).
We are looking for engineers who are interested in LLMOps, MLOps and DevOps and have some interest in AI; ideally, you have some exposure to the k8s ecosystem already.
If you're not well-versed in some areas but are eager to learn, we'd still love to hear from you. Motivation is much more important than experience to us.

Prokube.ai was founded in January out of Just Add AI. We have offices in Bremen and Hamburg.

We offer flexibility with location & hours and, if you are interested, the opportunity to contribute to open source.

Yes it is in the name, much like Federal Express. Not a distribution in a canonical meaning of the word. The idea of distributions is unique to Linux-based systems.
Does 20-m here stand for 20 meters or something else?

"We also demonstrate successful 20-m transmission at a data rate of over-200 Gbit/s data rate."
The overall structure is the same as in "use statistics to predict the next token."

With a Markov chain, the statistics are as simple as a mapping of n-grams to the number of times it appears in the corpus.

With a LLM, the statistics are the result of 50 years of research in neural network architectures, terabytes of training data, and many millions of dollars worth of hardware, along with the teams to build and manage all the data pipelines.

So yes, much more complicated.
The US dropped the atomic bomb in 1945. The USSR replicated their efforts by 1949, and both had ICBMs by the 1960s. The Chinese were late starters figuring the tech out by the 64s.

It is likely that nano-fabrication is harder than the atomic bomb - but betting on the Chinese not figuring this out just seems overoptomistic. They can bribe people. They can hire people. They can spy. They have some of the brightest scientists and engineers. They have enormous market, military and political incentives. They know what they are targeting and the tolerances they need. There is a good chance they crack this nut.

> How did that go for China and Russia during the last... 20 years of them throwing all their money and brain power at it?

ASML wasn't causing trouble until the Trump sanctions of 2018, up until then SMIC could just buy machines off them. The situation is different now and the research efforts will have kicked up a notch.
That's actually a somewhat useful visual.
I keep this open for usage during CTFs.

Not my experience at all. An individual review isn't much, but when you see the same ideas getting repeated across reviews, it's always accurate in my experience.

There's enough common agreement on what cozy or chill mean. There's plenty of signal in the noise of reviews.
That's unclear. Playing any recorded music typically requires a license fee to be paid even when it's "free" to the listener (for instance, the radio or a public venue)

Spotify pays based on payments from Premium users, as well as ad revenue. I presume others have similar arrangements.

wtf..up 11% in AH to $440.

Which is on top of 300% gains from 2022 lows. Those YouTube Meta obituaries were the worst possible timing ever. (Looking at you Coldfusion https://www.youtube.com/watch?v=g_i1alH5TrA )

It goes to show how just because something appears overbought does not mean it cannot keep going higher

Meta firing on all cylinders: Near-total dominance of social networking, chat, mobile ads, and now AI. Those mobile ads are so expensive, and multinationals and other large companies spending so much $ on clicks and impressions. High inflation pure top line growth. Crazy. It's hard to find a company that that is in a better position than Meta now. Maybe Nvidia.
> This has been covered several times

No, this has been covered exactly once. I asked 4 hours ago in this sub-thread this question, but you didn't answer it. I also asked again 3 hours ago in this sub-thread. I also asked a related question in another sub-thread 3 hours ago. You answered it one time 2 hours ago with "First thing you read. That's where definitions go." in the other sub-thread, then 1 hour ago in this sub-thread to its second query you said This has been covered several times which it absolutely not has been. THIS, dear readers, is what we call "bad faith."

> Given that you don't know how to clarify your original message, perhaps we can still salvage something here? Let's assume that OOP is by another definition. Your choice. Define it however you please. Then explain how relational databases fit into that definition.

Absolutely not. You have acted in bad faith, have been argumentative, have been snide, have been condescending, and have made things personal throughout these debates. I will absolutely not be corresponding with you in HN comments on this topic or on any other any longer. I would do so "in-person" in a Zoom call if you had the stones for it, but I doubt you do.

Surprisingly the CEO of Bayer, one of Germany's biggest companies, does not speak German despite living and working near Cologne. Apparently the board meetings are conducted in German... No idea how he manages to participate.
I believe you meant to link this: https://v8.dev/features/import-attributes

That page actually explains the change:

> V8 shipped the import assertions feature in v9.1. This feature allowed module import statements to include additional information by using the assert keyword. This additional information is currently used to import JSON and CSS modules inside JavaScript modules.

> Since then, import assertions has evolved into import attributes. The point of the feature remains the same: to allow module import statements to include additional information.

> The most important difference is that import assertions had assert-only semantics, while import attributes has more relaxed semantics. Assert-only semantics means that the additional information has no effect on how a module is loaded, only on whether it is loaded.

NB: The above quotes have been edited to just the most relevant notes. See the link above for more information.

This is why old secops/corpsec security hands are so religious about tabletop exercises, and what's so great about BadThingsDaily† on Twitter. Being prepared to do this kind of credential rotation takes discipline and preparation and, to be frank, most teams don't make that investment, including a lot of really smart, well-resourced ones.

If Cloudflare is in a position where their security team can make a call to rotate every secret and reimage every machine, and then that happens in some reasonable amount of time, that's pretty impressive.

As an employee, the Arbeitgeberbrutto is a number you never see. You’re not saying that employing people isn’t worth it, you’re saying that working in Germany isn’t worth it. Then you have to take the employee’s perspective, not the employer’s. Nobody advertises the true cost to the employer in other countries either. How much do all those benefits to US employees cost? Do you include that when you list US salaries, or do those get magically excluded because health insurance isn’t mandatory?

Your premise just seems fundamentally flawed.

> its an “age of imperialism” concept

At least in the late Roman Republic, there was absolutely a concept of race that unified e.g. the various Gallic tribes, or differentiated the peoples of the Roman East. It's always been a sociopolitcal concept. But the Romans were aware of e.g. North Africans versus dark-skinned Africans.
It works by computing that P(queen|"king-man+woman", corpus) > P(<other-words>|"king-man+woman", corpus), i.e. it predicts that the most likely next token after that phrase, based on the entire training corpus and the loss function, is "queen".

Now, how exactly the LLM is computing this prediction remains poorly understood.
There's a text under the star avatar of bard which tells you what model it is using... except only a select few people get it.

What would be nice is a way of having that generic +, but making it as efficient as builtin + on the standard numeric types. CL implementations do not currently have that capability (except perhaps if they make builtin + rather slow).

IMO it does provide a better user experience. It gets to the end goal quickly by giving you a list of places directly in the Maps app. You can see how far each place is and if you really wanna go to that part of the town from a bird's eye view. Sure, I can Google the same query. But that'd require me multiple clicks and scrolling through possibly long-winded blogs to finally get a list of addresses.

OK! That's helpful.

The only unserious code in this post, for what it's worth, is a couple functions that make an authenticated stream cipher out of HMAC, because the Python standard library doesn't have an encryption function that I could find.
yes, glass has a non zero amount of absorption which is why Erbium amplification is required.
I agree it’s not compelling. In fact I think typing all those words is a waste of time. I use Yelp and here’s what the experience is like:

1. Type “lunch”. It auto suggests “lunch restaurants”

2. It already has my location but of course it can auto complete a different one.

3. Press the $ button to filter to upscale, aka higher priced, restaurants with $$$ and $$$$.

Very quick. I guess the advantage for AI is finding “favored by locals”.

> > Women typically have two X chromosomes

> Isn't this actually the definition of female?

‘Women’ and ‘female’ are not interchangeable; one is a gender characteristic, the other is a sex characteristic. The statement as made is valid: Women are statistically likely to be XX, rather than XY or XXY or no doubt many other variations. ‘XX is female’ is a convenient rubric that is easy to remember, but as is usual for such things, human bodies do not respect convenient rubrics regarding genetics and sexes.

Doubtful. TED's last stable release was in 2013, and that's the lightweight one I'm familiar with.

Markdown text might be fine, but I wouldn't expect markdown to PDF via pandoc to be particuarly "lightweight." There's the range of typesetting or desktop publishing stuff like TeXmacs, groff, or LyX, but I don't expect those to be particularly light, either. There's WordGrinder, a terminal based word processor, but I've never used that.
I agree. Government recognized corporations are formed/created "under" the government in cooperation with the "owners". In exchange for agreeing to being "under" the laws of the government and being regulated by the government the owners get limited liability. If humans don't want that privilege, they are more than welcome to operate under full liability and open up all their assets to any claims made against them...

The reason why women go out more IS because there is less crime.
