> Most people don't run metal today

We are seeing an increasing trend towards On-prem/Cloud-prem/Co-los[0], mainly due to cost and reduced complexity. Inversely, most smaller companies (1-10 emp) who use hyperscalers do not use their metal offerings, because of cost. They wish to scale with demand which metal cannot provide. Using EKS and other similar services have the benefit of being familiar and elastic, but are in fact slow and soon become quite expensive[1].

> How many people know unikernels?

This has been a goal of Unikraft for a long time, to make using unikernels simple and familiar to use (in fact, transparent). This is why we use OCI images as the root filesystem; why it's possible to start unikernels through Docker; why we have several types of Kubernetes integrations.

> How do you debug a running app?

For one, you can attach a gdb server and step through both application code and kernel code together. Secondly, at Unikraft at least, we are introducing a virtual shell that allows you to introspect the filesystem, main threads, see system stats, etc.

> Stripped down Linux distros reduces attack surface

This is may reduce the attack surface, but one bad-actor application can still take down the host and all the other containers since they are still process (software) isolated. With unikernels you get hardware-level isolation AND, interestingly, the performance thanks to the lack of strong syscall boundaries.

> Unikernels increase complexity

Give us a chance and try out one of our examples :-)

>I often don't bring my bags with me, because I'm going to have to load everything into the car anyway.

Thats an interesting optimization. Don't bag your stuff in the store just walk out with a cart of loose groceries. Especially for someone who simply MUST bring all the groceries inside with one trip, I can just load up a crate.

I've foisted no expectations, I have only posed some questions or requests for clarifying detail regarding your facts.

Please do not misrepresent reality, it is rude, and can be harmful. If you would like others to be concerned about the safety of the collective, you should reciprocate.

Do you believe yourself to know why people don't want to engage with me, or that I wonder about such things? How could you possibly acquire such knowledge?

> then claim it is the science that is wrong.

I made no such claim (though, I did criticize the questionably accurate memetic reputation and marketing of "science", the institution that proclaims in their scriptures and marketing (though not so much in behavior) to welcome all criticism), why are you speaking as if I have? Are you perhaps "trying" (I use quotes, as it may seem like I am implying conscious intent, which I am not) to trick people into believing something that is not true, are you perhaps at least to some degree engaging in rhetoric in order to persuade other people to believe your preferred story?

It's grounded on launch with it's own concrete shoes.

Apple released a VR headset that you can't use to play video games or watch porn with, and priced it at ~2-6x the price of competitive hardware.
Curious, what challenges would git still have to deal with to work with big repos?

500 GB isn't all that much data in 2024, as long as you can resume a broken network connection on fetch (like using HTTP range requests if using http, and when using git LFS), and while 15 million files is a pain in most file systems because of all the overhead, a relatively modern NVMe SSD should be able to cope with it just fine, but I don't know enough about the innermost internals of git on how it manages files. Is there something that's inherently slow/expensive that doesn't scale well with the number of files?

(Basically, I'm trying to find a non-rhetorical answer to the question of "Why not?")
I only use TS on the frontend, so less opinionated about some of this.

I’d love to see some of the codebases where people complain about performance so I could profile them myself. Would put money on being able to improve the situation by orders of magnitude without switching stack.

We use Python on the backend of our web app for realtime image recognition and it’s fine because we’ve been thoughtful about data structures and algorithms.

The computer won, marking the first time that a computer had beaten a human player in a chess-like game

I'm a huge privacy advocate and don't think stores should track what you buy at all, so don't confuse what I say next with the is/ought fallacy.

They already have perfect resolution and data retention of everything you buy at checkout time when it's scanned, plus they can verify your identity rather than have to rely on facial recognition or other things. I don't think this is any creepier than what they already do so from their perspective it is "common sense."

Yes, same in the UK. Most stores have scan as you shop, but most people do self checkout. I get the impression scan as you shop is seen as being a bit prissy.

Good ol' "SIGGRAPH realtime", when a graphics paper describes itself as achieving realtime speeds you always have to double check that they mean actually realtime and not "640x480 at 20fps on the most expensive hardware money can buy". Anything can be realtime if you set the bar low enough.
Can someone convince me that 3D gaussian splatting isn't a dead end? It's an order of magnitude too slow to render and order of magnitude too much data. It's like raster vs raytrace all over again. Raster will always be faster than raytracing. So even if raytracing gets 10x faster so too will raster.

I think generating traditional geometry and materials from gaussian point clouds is maybe interesting. But photogrammetry has already been a thing for quite awhile. Trying to render a giant city in real time via splats doesn't feel like "the right thing".

It's definitely cool and fun and exciting. I'm just not sure that it will ever be useful in practice? Maybe! I'm definitely not an expert so my question is genuine.
Checking for Linux makes sense. Doing the exact same check for Linux five times in a row is mysterious.

Here's what I want to build:

A rotatable, table-top round disc base, with a contraption to keep a mobile phone straight and stable. The stand itself will have 4 small unidirectional mics, to figure out which direction (after filtering for human frequencies, ideally) is the sound coming in. And based on that, it will rotate the phone to face that direction (continuosly).

The use case is family video calls that I do frequently from my dining table (my whole family is sitting around the table, hence there is no one good spot to keep the phone). With this self-rotating stand, the phone will auto-rotate towards whoever is speaking.

I can write audio-processing code, but I have no idea how to get started with the hardware. Feel free to steal my idea, but please share with me how you are building it. I just want this to exist, and I want to know how to build it for myself as a fun project.

Impossible here because the exploit was carefully engineered to be unreplayable and NOBUS (nobody but us) so it couldn’t go viral. Even if you intercepted a complete tcp byte trace of the attack there was nothing you could do with that to attack other systems.

Pyodide uses its own event loop which just subscribes to the JavaScript event loop. My suspicion is that this will be more efficient than using uvloop since v8's event loop is quite well optimized. It also allows us to await JavaScript thenables from Python and Python awaitables from JavaScript, whereas I would be worried about how this behaves with separate event loops. Also, porting uvloop would probably be hard.

My personal theory is people were easily "tagged" somehow like the famous umbrella tap attack, maybe a laced drink, and then the area they were known to be in was radiated with a specially calibrated radio wave. Without an obvious poison these people would be written off, yet they would be too sick to function, perfect sabotage without being credited.
I do the same with my washer. I monitor the power usage, save it in a variable and run a trigger when it drops from a certain amount below another.

Gen 1 iPad was a bit meh. Thick, heavy, didn’t do much. Kinda just a tech demo for a large very-responsive touchscreen device.

Gen 2 was so perfect that they sold it for years and years, and launched a related product line based on its platform (the Mini).
Interesting! Citation?
It does sound like a person was watching the shopper live:

> Though it seemed completely automated, Just Walk Out relied on more than 1,000 people in India watching and labeling videos to ensure accurate checkouts. The cashiers were simply moved off-site, and they watched you as you shopped.

But who knows, tech articles are so inaccurate that it might as well have been some misunderstanding regarding how the labeling/training was done.
I said nothing of the sort.

I find the Gentoo ebuild repository, mirrored at http://github.com/gentoo/gentoo often is a stress test for git clients due to the sheer number of commits.

It's interesting to see the definition of scale stretched in all kinds of different directions.
Speaking of visualization...that last figure in this post is super interesting in part because you can actually see some of the redundancy in the base64 encoding on the left, in the patterns of vertical lines.

In general, better compression means output that looks more like "randomness"—any redundancy implies there was room for more compression—and that figure makes this quite clear visually!
> Looks like private flights are actually much more dangerous than airlines

Most of the accidents involve small one-engine aircraft that owners personally fly. They're technically "private," but what's relevant here is large private planes like Gulfstreams, Bombardier Globals, Dassault Falcons, Boeing BBJs, and the like..they're safer than airlines.

Stop and Shop (in New England) had hand scanners you could do this with 15 years ago. I have been shocked that the technology didn't spread. It was so easy to scan and bag then just plug the scanner in at checkout and pay.
Curious that neither party recognized 80/20 as being unfair. There is just as much non-technical work required to get a business off the ground as there is technical work. And if one or both parties did recognize it as being unfair, thinking they could capitalize on the other's misfortune, that is not good ground to start a relationship on. At least the bullet was dodged.
My understanding is that there was a period of time where computer science was very excited about fuzzy logic, because it was thought it would prove to be more powerful than conventional logic.

https://en.wikipedia.org/wiki/Fuzzy_logic

However, it was demonstrated that it had no additional power over conventional logic, so interest faded as quickly as it rose. Which is not to say it is useless, but that rather than a revolution it became just another tool in the belt. It can be more convenient to formulate certain systems in fuzzy logic rather than binary logic, but it doesn't really create new possibilities. And programmers in the trenches were doing this sort of thing already anyhow, less formally, but generally effectively.

It was weird how loud it was for sure. New forms of logic don't generally get the red carpet treatment like that.

I don't know why a rice cooker would particularly care about "fuzzy logic" other than a bizarre marketing spandrel [1].

When we bought our house we had 3 city trees which were Bradford pear trees. We lots two of them during rainy season. One lost a major branch. The other got uprooted. I've read Bradford tree

I'm in California. Our city doesn't allow Bradford pear trees anymore. When we bought our hour we had three Bradford pear trees. Over time we lost two of them during rainy seasons. One got uprooted and the other broke off a major branch. Both times it was fortunate that nobody was injured or property got damaged. Ended up replacing them all.

Sounds like you're experiencing BAS, Bad Architecture Syndrome.

Application servers should scale out, sure you might need a few more for Node than Rust, but is that really where the issue lies?

You wouldn't implement Postgres, Ceph, QEMU or the kernel in Node... But the CRUD part of most applications will be fine in "any slow language"

Why not? what makes it unpopular?
"Ginger Market" on the SJSU campus has attempted to use a similar "Just Walk Out" approach. It has not worked well. I've been double charged, charged for items I did not take, not charged for items I've taken, etc. The refund process was also a pain. It was so bad that they had to stop using it last spring, although they claim they are going to give it another go.

Why even bother? Self checkout or a cashier work so much better and I have a hard time believing they are less expensive. The store is plastered with cameras. Seriously, there must be 100 cameras in the place. That's a lot of video to process, which has got to be costly, whether it is a machine or people who are reviewing it.
> Though it seemed completely automated, Just Walk Out relied on more than 1,000 people in India watching and labeling videos to ensure accurate checkouts.

Yup.

I got the chance to go shopping at one in 2018 (so it's been a while). You could tell there was some "reconciliation" happening, because your receipt didn't show up until 20-30 minutes after you left. My guess is that this was some person via mechanical turk crawling thru the data and indexing what you -really- bought.

Of course, my colleague and I (who were working on computer vision at the time) did stuff like take our bags off, put them in the middle of the floor, and roll a can of soda into the bag, just to see what would happen.
A consortium is a great way to get money and power into those maintainers. Never said they should take the power from them or provide code. I think people are hearing their own mind here, not mine.
They are invasive (in the US) and grow like weeds completely taking over and crowding out native species. Having many of them screws up the nitrogen level of the soil further crowding out/killing native plants.

This alters the ecosystem.
> Using an ICE base platform for EVs doesn't make sense,

Kind of. Renault's small sized EVs share parts of the platform as some ICE models (e.g. Clio/Renault 5 E-Tech) which allows them to reduce costs of the EV model. Considering their target audience and market segment (small city-focused EV with city-scale range) the tradeoff is perfectly acceptable.

> and there is no EV base platform for sale/license

How do you know this? Renault for instance are in a pretty specific spot, market wise, and they were trying to merge with Fiat-Chrysler before the latter ended up with PSA (Peugeot, Citroen, Opel) in Stellantis. They have some EV tech, especially on the cheap city-focused side (Dacia Spring, Renault Zoe, Renault 5 E-tech), and would probably be open to collaborating / sharing risks. This is purely conjecture of course.

Also, Subaru managed to license Toyota's EV tech.

Except all these trillion dollar valuations in the AI bubble are based on the belief that AI is replacing humans, not just outsourcing to cheaper humans.

Of course outsourcing to cheaper humans can be great. But that's not what tech is shilling to the world as "AI" right now.
I guess I don't get it -- if you've founded a company and it went successfully enough to where you can be an LP (or you are otherwise independently wealthy), why would you join an early stage company full-time as an IC when you could join as a consultant or advisor to smoke out whether the collaboration is a good fit for you?
I love rice cookers!

Rice cookers (usually) make clever use of 1) alloys whose magnetism depends on temperature and 2) the fact that boiling water occurs at a fixed temperature. With a "trigger" temperature just above the boiling point of water, the rice cooker automatically turns off the heating element when all the water is gone (and thus the temperature starts to rise above boiling point).

Presumably, this is can be used as the first stage in a pipeline. Take the models and textures generated from source data using this, cached it, and stream that data to clients for local rendering.

This might actually drag me into the apple ecosystem. It's a nice ecosystem, it's largely POSIX compliant, but to get the most out of it you should be using IOS devices, and that's just too locked down for me.
Notably there haven't been advances in regulations the way there was after the Enron fraud. Of course it is not clear that SOX was overall an improvement because in the end it gave us mega-tech companies like Facebook and Google and SPACs for everyone else.

I think many governments don't want to regulate crypto because they don't want to legitimize it but they are getting dragged into with Bitcoin ETFs and such.
Bradford pears were all the rage in the 1990s to 2000s. At one point HOAs thought these were the best tree. Local gardens and nurseries would sell lots of them to landscapers and homeowners.

To this day, they're all over my home state of Georgia. And they're still selected for new landscaping.

They did have a few pros:

- Look great in the spring

- Huge, lush, thick canopy in the summer

- Fast growing

But there are way too many problems:

- Kills all the grass underneath them from shade and root structure

- Seedlings and root offshoots are pervasive pests

- Produces a lot of fruit, and it's toxic to humans and dogs. It smells bad and can smear if you step on it

- Trees only live 7 - 15 years, and they leave a gnarly root system to deal with.

- Extremely prone to falling over during winds or tornadoes. Can easily damage fences, housing, etc. We had to replace our fence once because of one. Even small storms can bring down the older trees.

- And of course, everyone knows how awful they smell in the spring
To be clear, that's a problem with your attention span, and not with the creator.
