I'm on the verge of contributing to the Kickstarter, trying to get a sense of what I'm seeing:

1) http://www.litiholo.com/images/buzz-on-the-printer-crop-809x... Wondering what the artifacting is on the left side of the hologram itself? Is this a problem with this specific hologram, or will all holograms have this artifacting?

2) Same image, but I'm not quite sure Buzz is centered in the middle of the ... work plate? Glass? Others are a bit more aligned to the edges, but are instead offset in various directions. For aesthetics, what would prevent a hologram from being perfectly centered and rotated to the plate?

3) They all have a little stray hologram pixel in the top right corner of each hologram, intentional? Fixable? Shortcoming of the technique?

4) A lot of the plates look a little smudged/finger-printy. Is it possible to clean the hologram plates/film after "printing" to have a clean shiny surface?

5) I don't see an example of an image that has been printed corner-to-corner? How much of this hologram film has been applied? Is it possible to make a full plate hologram? And/or trim the edges afterwards? (It looks like glass plates, so... probably hard for a layperson to cut?)

6) Open source firmware? Gcode? Toolchain? Hacker friendly? (Ctrl-f Firm, Open, or Code resulted in 0 results.)

Just to end in a compliment sandwich, it's totally cool and would definitely have a place in budding maker's labs, and new niche stores! I could see the output being relatively popular on like... Etsy. Super affordable at $1,600 when stacked next to a 3D Printer, or Laser Cutter, etc. I love the idea and DO want one of my own... But trying to identify the shortcomings.
Expensive. I've got all these machines sitting here at home, why not use those?

A side note, how do you use Kubernetes to set up HTTPS on wildcard DNS? Is there a service for autoconfiguring the DNS and getting the certificate without a forward proxy?
Maybe this is the wrong definition but I read “true hologram” to mean a 3D image made of light, this looks more like one of those images that used to be on the cover of Guinness World Records.

Edit: I see OP is the founder and this is a smaller project. Looks really cool and sorry if that sounded negative! Just not what I expected from the title.
Nothing is that simple. We are complicate biological machines. This case clearly shows that.

The problem is if you don't use the vaccine, you won't find out what problems there are. We are talking about single digits of cases for more than 1 million vaccinated persons.

Whereas in the UK, they vaccinated even more people and have apparently no deaths.
On my world those decisions come with project budget, if no department puts the money to hire the consultants that would do the job, there is no transition.
> Have you never met someone who opened a restaurant?

Yes, two actually. Restaurants are incredibly difficult businesses to succeed in. But, to answer your question: my brother-in-law ran a pizza/sub restaurant in a small town, and a friend of mine ran a fancy restaurant in a resort town.

Both of them are tricky situations. My brother-in-law sold his business after being moderately successful (he did it full time and made a living for himself, but it was a lot of work for what he took home). He sold to form a new business with his wife, which is very successful. My brother-in-law, though, had no loans and started the business while living with mom/dad so had it failed, he'd have been out his "life savings (at 22) with no paycheck coming in". He ended up with a business that could sustain itself and him, and did so for a few years, but just barely.

My friend's fancy restaurant completely failed. His restaurant was one of the best places I've ever eaten[0], located in a lake-house town where my family has a vacation house. He lived upstairs with his family, and the place was packed during the summer, but he couldn't charge what he needed to charge to re-coupe the cost of the quality of food he served. His business failed, he moved out of town and went back to teaching but I believe he's opened up a new place out of state, recently.

Did they both expect to be successful? Yes. And since I didn't know Andy (fancy place) prior to his restaurant, I can't say for sure what his thinking was going into it, but the first year he was open he admitted that he knew he was taking a huge risk -- there is literally no business between October and May, and previous fancy places like this have failed regularly in that city. It's a bummer -- this place was amazing.

[0] It was a place you could go on the weekend and were bound to run into a local celebrity/basketball/football/baseball player; it busy/reservation only but small. He was only open Thu-Sun, everything locally sourced and the menu that day based on the best of what he could find (usually bought that morning).

The amusing thing to me is that, googling what a good time on the Nurburgring is, it looks like the fastest (street-legal) cars are high 6 minutes, and 7 minutes will still get you into the top 10.

So a passenger van is only 50% slower than the best-in-class. It's probably only 20-30% slower than your typical "fast car".
The reverse is true as well though. If you learn Kubernetes and set up a cluster to host a blog, you'll find that it is now trivial to deploy a hundred other things to it.
On the topic of "takes too long to learn" can someone recommend a good tutorial on basic Kubernetes concepts?
I think the "rust" comes not from the fact that the technology is aging, but that we're dealing with metal oxides. Tapes, then, are spooled rust.

I find your extreme negative reaction to his success kind of amusing.
This canard is still being trailed out?

Excess death counts are available, and they are even higher than the COVID death counts, suggesting that the official count may actually be an underestimate of total fatalities. However, the claim that that it is "way over stated" is not borne out by the actual statistics.
Last March, a family friend was in ICU due to Covid. They were given heparin shots in hospital and sent home later and told to take baby aspirin. So it seems Covid itself may causes blood clotting. Is it surprising that the vaccines may as well?

I use Jobs for helm hooks like integration testing and DB migrations associated with deployments. They work great for one off workloads like that.
My understanding is that early draws were generally condoned in this specific case bc this tournament format was especially long-winded (15 games before playoffs started). And, this was the final round of games.
The big difference is that kubernetes YAML is in a change control system, and specifies what you want rather than how you get it.
I just want to know what the `-> *` is all about. I assume `->` is a pipe like sugar, but what about the asterisk?
> It's a trust issue. I don't trust my passwords on someone else's server.

They don't have your decryption key, therefore they save encrypted blobs and have no means to obtain your password. This takes care of trust issue - it simply is not an issue and never will be.

Even if malicious employee does something out of the ordinary or "hacker" gets the database, they still have the impossible task of breaking the encryption (which for all intents and purposes is impossible as of right now).

This returns us back to my starting point - there's *no objective* reason to use bitwarden_rs, apart from curiosity and/or convenience. I'm not saying it SHOULD not be used. We are all free to make choices as we see fit and don't need to justify them, however the reasons you listed are not reasons at all because the concerns you have don't exist.
When another country or organization turns their drones on us because of our antiquated human rights ideas, inability to form consensus, and extreme ideologies - from their perspective - opinions will get much clearer.

Best way to stop the drone wars at this point are for us to stop now.
It actually looks pretty good!. I like the aesthetics. Any chance You are able to open-source the templates?

Interesting point. Maybe the user could toggle the animations on and off. But back then, I hadn't designed this tool with the idea of creating a standard-ish colorpicker in mind.
Why don't you just disable the updater then?

Show HN: is for things Hacker News readers can 'try out'...

I wish Adobe would use a different name for this that made it more obvious what was happening, something like "detail fill" or "detail interpolation".

I worry this is going to be a case where the marketing is at direct odds with public education efforts.
happy to have you onboard. Feel free to reach out if you need any help :)
I would look at it from a habit forming perspective. I would suggest reading the book "The Power of Habit: Why We Do What We Do In Life" by Charles Duhigg. How we form habits and how we can change them is fascinating reading on it's own. This book takes a more scientific approach to understanding habit formation than other books of this sort tend to do.

Read the book or just read up on the cue, routine, reward loop and how it can be hacked to change habits or form new ones. The author also goes into detail about how to build up your willpower, which will also help immensely.

You've probably formed habits that have been reinforced over time that are detrimental to your goal of working on hobbies. This book can help change that.
That's not a fixup commit, it's a rebase. It's missing the point of fixup commits which is to commit now and defer the rebase until later.

It's also completely missing the point of the feature under discussion here which is to automatically decide which commit to squash the fix into.
Just create a format where every win is rewarded if you dont like (quick) draws. Why would a spectator care about a game that has nothing on the line?
Also what market is there for big hard drives outside of FAANG and a few other places?

Retailers in my area (e.g. Best Buy) don't stock hard drives larger than 4 TB; I was going to tell somebody who lived in the Valley that he's lucky to be able to go to Fry's and then Fry's closed down.

Those same retailers stock both budget and quality SSD's up to 2TB in size. Most upgraders and the system builders are happy.

For the rest of us there is Amazon where the Seagate Exos "enterprise" drive costs half of what similar "consumer" drives cost, has a great reputation and does not seem hard to live with at home.

I would not take it for granted at all that a backup, RAID rebuild, restore, metadata scan or any full scan would work on such a disk if I hadn't tested it -- it is just that kind of technology. Synology is not crazy at all when they make you buy branded large drives to go in the enclosure.
Unrelated, as an aside ...

I really am enjoying the developer Q&A interviews that console.dev is putting out.

They're very much like the "usesthis"[1] profiles but more in-depth and with more interesting details ...

The site is literally about CSS color names for 256-bit colors, it’s not a palette site with beautiful colors. This is a ridiculous feature request, but I can’t say I’m not used to this.
Wow, nifty work!

Reading that source brings a rush of emotional memory of that incredible instruction set. So simple, so rational, so orthogonal. Ah bliss(-11 ;-).
Jobs can get useful in more complex workflows. The most common use I’ve had for them us running a smoke test suite or a database migration as part of the larger workflow for a big Rails app.
Some of these colour names make little sense. For example, 'chocolate' is surprisingly light. 'brown' is red.
The Nintendo 3DS seems like it's in this vein too— a lenticular display coupled to gyros and eye-tracking.

Does these holograms work for more than one viewer at once?
What's different is that the applications and the infrastructure are all managed and stored in the same location. There's a lot less you have to keep track of. Sure, you can get it all done and have it stable the traditional way, but k8s makes it fun!
This is definitely a cool way of exploring CSS colors.

But, serious question: does anyone actually use CSS colors except for a handful of the basics ("red", "blue") for prototyping/debugging?

I mean, the idea of typing "background-color: lightsalmon;" just feels so bizarre to me.

Whenever I've needed to come up with colors from scratch, I'll just start with an intuitive best guess -- e.g. "hsl(30, 80%, 50%)" -- and then iterate a couple times till I get what I'm looking for.

It seems like even more effort to try to select colors from the CSS palette when it might turn out that there isn't even a satisfactory one. The CSS colors are still extremely limited. E.g. the distance between neighbors like "dark cyan" and "darkslategray" is huge.
Interesting. Here is Peru on the CSSWG draft document[1]. Other then rebeccapurple[2][3] is there any rationale given for the names of the CSS colors?

Each hogel is actually a real laser-encoded holograms. So trying to make the distinction between lenticulars, Pepper's Ghost, etc. that use the name "hologram", but are not.

This hogel approach to recording the hologram in segments allows of capturing people, computer graphics, and much more than analog holograms that can only capture inanimate object. However our LitiHolo film can do analog holograms as well, if interested.

"Although the long-term goal is to model all 959 cells of the C. elegans, the first stage is to model the worm's locomotion by simulating the 302 neurons and 95 muscle cells."
You've listed a dozen or so other technologies you've had to learn in the past, which in aggregate required much more effort and experience to master. Much of which provides a good foundation for understanding the concepts that kubernetes builds upon.

I feel like this was more of a hyperbolic rant.
I see the same thing in the Netherlands; the way some people talk you would almost get the impression that Floyd was killed in Amsterdam or something.

Not that we don't have problems with racism – we absolutely do – but the context and reasons are just completely different to the point where the American conversation on the topic for the most part just doesn't apply at all, but unfortunately not everyone seems to have realized this.
Some countries' populations are already decreasing, like Japan, and more are following close on the same path.

Why? It is cheaper to run redundant disks and power supplies with single mainboard than to run two mainboards.
Yes. The combination of erasure coding plus regular scrubbing is already the standard in the largest proprietary storage systems. As it happens, I worked on exactly the scrubbing piece ("anti entropy") for such a system at Facebook. There was a lot of analysis of data-loss probabilities based on encodings, placement across power/network domains, scrub rates, repair rates, etc. Since there are also performance and resource-use implications behind many of these, it's actually a very complex balancing act. That's why the knowledge of these second- or third-order problems and their solutions is slowly filtering down to storage systems you can deploy yourself.
My reaction:

Why? Oh that makes sense. Wait! Abysmal Security Nightmare! Nooooooo Don't do that, Pleeeeeeease.

One of the main reason is that:

1. It increases the attack surface.

2. At least currently PR_SET_NO_NEW_PRIVS must not be relied on to be perfect for security. Must use cases use it as an additional security layer, but the chroot patch uses it as a fundamental required to be perfect building block.

3. As far as I can tell the benefit it gives is not worth the increased attack surface even if PR_SET_NO_NEW_PRIVS would work perfectly. But I might be wrong.

Honestly the additional constraints it puts on chroot are good and I believe should be fulfilled for must use cases of chroot. So I think best would be either a "CAP_RESTRICTED_CHROOT" capability which allows chroot but only under given circumstances or a prctrl which "degrades" CAP_SYS_CHROOT to only work under given circumstances.

In both cases programs which drop all CAP's they don't need would not be affected by this feature made for programs which use chroot.

But in the current design the sandbox of ALL!!!! sandboxed programs which drop the CAP_SYS_CHROOT capability is weakened. Which IMHO is unreasonable.
Nit: With some companies paying below average, too, by the very definition of the term 'average', and also because the sizeable handful of FAANG companies skews the average even higher.

Some of these concerns are valid (in particular the microbiome and the possibility and probability of unforeseen variables) but others are not.

Even assuming that we can't use mirror arrays to use natural lighting within habitats like O'Neil envisioned, there is nothing about sunlight that we cannot replicate with artificial lighting. In fact, we could make a safer substitute that forgoes the ultraviolet radiation.

It also doesn't take that much radiation shielding to do a better job of protecting us against cosmic radiation than the Earth does. While there is 100 KM of atmosphere between us and the vacuum, that is air and of a density that drops sharply with altitude. We could easily match and exceed that protection with plating of about 20 metres.

The reason why radiation is such a concern in space travel at the moment is because current launch costs prevents any but the most spartan kinds of shielding from being economically viable. Once we can construct launch assist devices like rotavators and orbital rings, that is not going to be a major limitation anymore.

>>Vaccinating with AZ is much more useful than it is dangerous. By several orders of magnitude.

You are right! But the human factor is important to consider here. People aren't machines that will bend over for the collective good of the society. It's important that people's trust in vaccines and the approval process is maintained even at the cost of a slight delay. There are half a dozen vaccine makers who can step up to make up the shortfall.
Let's assume I have backups for both my kube configs and my standalone machine... and spare parts for the cluster(s). I'm trying to understand better the maintenance story, because my impression is that kube itself has spec changes, and I have to stay on top of all the dockerfiles I'm using to keep up with patches there?
Check out "I Am a Strange Loop" if you haven't. It's like GEB, but he had a few more decades to refine the ideas. Both great books though!
I run Bitwarden official on a Hetzner dedicated box, the machine costs ~40€ a month, Bitwarden usage does not even register as statistical error, therefore resource consumption is really not such a concern.

There's really no objective reason to use bitwarden_rs. Subjectively - we can do whatever we like, I'm not trying to challenge anyone into providing their reasons or into justifying their decisions, there's no right or wrong here.
Why yes ofcourse. Let's worry about the stuff that doesn't take years to master. Silly me.
Sure, there are going to be smaller players, but they won't matter in the grand scheme of things. The FBI, or DOD isn't going to go scouring the crevices of the web and look through various sources, they want one big database that's easy to query, and likewise, a company like Clearwater wants to get big so it can be in a position of power, and of course, $$$.
Where the 3DS is lenticular, these are real laser-formed holograms, and can be seen by multiple viewers without any headset or other gear. Right now view zone is 45 degrees.
Making a website is a distraction from the hard work of finding a job.

If you want a job, you have to knock on a lot of doors and face a lot of rejection.

Nobody is going to find your website and hire you that way...yes it sucks.

Good luck.

I am unironically using Kubernetes for my personal home server. Thanks to https://k3s.io/ this is really easy to do, great fun and extremely useful.

I have a git repo containing all my helm charts & docker files, testing & deploying changes is absolutely trivial now. And it's great to have everything version controlled.

Previously I used to use Ansible, but you quickly run into issues which make you want containerization: Conflicting library/tool versions, packages that pollute too much of the system, port conflicts, hassle of keeping the playbook idempotent, etc.

So while docker-compose would also do fine, having kubernetes to manage the ingress' routing system is rather practical. And the same goes for the other bits and bobs of infrastructure offers you if you're already using it. It's just very convenient.

I've been doing this for a few years now, and am now up to 14 different apps running on my single home machine in Kubernetes, ranging from Home Assistant to PostgreSQL to Plex.

Also it's just good experience. I also use Kubernetes for work, and this has made me noticeably more proficient.

Living in London (specifically Haringey, which is mentioned in the article), I was amazed - positively - when my residential street switched to directed, white, LED light.

It lit the street and not everything else.

I could see a few stars in the night sky, for the first time since moving to London.

I no longer had to deal so carefully with light leaking into my bedroom.
As silly as this is from a chess point of view, I really genuinely enjoyed watching Hikaru Nakamura's face as he sees the opening. Needed a good laugh!
As someone who grew up in a family of pet owners, the joke is anytime there is a story with "study" and "dog", that any dog owner could have told them that. This study is what we refer to as the "invisible leash" that dogs have with with their masters. The article also touches on mirroring behavior, which is also well known and even has a whole class of dog training based around it called "Do as I Do"[1] I trained my dog this way as a pup. AMA.

Dogs spend their lives trying to figure out what we want and the meaning of our words. Science has year to catch up to learn just how much they understand and how in-tune they are with their adopted pack.
