> cbor doesn't prescribe sending schema, in fact there is no schema, like json.

You are right, I must have confused CBOR with BSON where you send field names as strings.

>on top of it, i am saving approx. 20% in message size compared to protobuf bc i am using mostly arrays with fixed position parameters

Arrays with fixed position is always going to be the most compact format, but that means that you essentially give up on serialization. Also, when you have a large structure (e. g. full set of device state and settings)where most of the fields only change infrequently, it makes sense to only send what's changed, and then TLV is significantly better.

My unhelpful answer is that I usually begin an unproductive procrastination loop wherein I overanalyze different alternative programming languages, frameworks, libraries, and possible ways to build software. I read a ton of books and tutorials and then never build the thing. Oh and I spend way too much time here and on other websites.

My helpful answer is that occasionally I break out of this procrastination loop and just start making something I think would be cool. It doesn't have to be anything new or exciting, just something that will keep my interest or even better scratch my own itch.

One of the biggest lies we tell ourselves is that you shouldn't reinvent the wheel. This couldn't be further from the truth. Just imagine if people actually followed this advice in the technology space. Almost all of the software that you use on a daily basis is a reinvented wheel.

“It's not a good metric but it's easy to calculate so let's use that to make a completely nonsensical point”.

Did you know what happened like this week, with the military parade stuff and financial institutions being told to behave around that because the government didn't want any market turbulence around their glorious parade?

The reality is that Chinese government has total control over the entirety of the Chinese economy. They don't exert their entire control all the time and let things go around as long as it doesn't interfere with their agenda, but it will interfere in absolutely anything whenever they decide for whatever preposterous reason like a military parade or anything.

From 2022, a contemporaneous account of the Biden antipathy: https://www.detroitnews.com/story/business/autos/2022/02/03/...

While I didn't look long for a more neutral source, Teslarati has a good list of the prompts of the shift from Musk being anti-Trump and pro-Biden, to giving up on Biden, to supporting Trump: https://www.teslarati.com/former-tesla-exec-confirms-wsj-rep...

There were apparently also other considerations not associated with Tesla for his turn (transgender child, etc), but my read on all this is that Musk saw staying out of politics didn't mean politics would stay away from him. Given that Trump II is also now somewhat anti-Musk, it's not clear to me that he succeeded in avoiding a longer-term axe for Tesla (Neuralink/Solarcity/SpaceX/Boring...) from politicians. We'll see.

> "Only cladistically" is a bit like saying "only in reality" imo.

In the sense that "imo" means "in my opinion, not necessarily in reality".

Clades are just a view on biology. It's not the only one. Otherwise, very few things in biology would exist.

> Well.. eel-like probably more I'd guess.

Still a fish.

The only people who want to see fish cladistically are the ones who don't want fish to be a thing. Fish are obviously a thing, and they are obviously not a clade. It describes function: water, gills, spine.

> eels are not fish

Many disagree.

You don't need to get sun burns to get skin cancer, but there is of course a strong correlation.

Australia does have the highest records of skin cancer diagnosis per capita though, and it has for some time. [1] The reason for it is for a few reasons.

A prevalance of outdoors focused lifestyles, exasperated by a higher amount of UV penetration to the ground due to proximity to the equator, and a much smaller/thinner O-zone layer than anywhere else in the world. This applies to both Australia and New Zealand btw.

Both due to the location, and man made causes (e.g., CFC's) [2]. Though fortunately, the O-zone layer is getting much better and quite quickly. The article I linked states the ozone layer will be at pre-1980 levels by 2050. Taking this at face value without much scrutiny though.

Australian's statistically have fairer skin. I'm half Cypriot by mother's, Norweigan. I did not get my fathers complexion ;-).

Throw in the sheer number of people who travel here from places where the ozone is much stronger/better, means people enjoying our lifestyle without the same level of protection warranted. I thiink this risk is overstated though, I made the mistake of not using enough sunscrean or clothing once, and got the most hellish skin burn. You only ever make that mistake once.

It depends on how you define the math involved.

Locally it's all just linear algebra with an occasional nonlinear function. That is all straightforward. And by straightforward I mean you'd cover it in an undergrad engineering class -- you don't need to be a math major or anything.

Similarly CPUs are composed of simple logic operations that are each easy to understand. I'm willing to believe that designing a CPU requires more math than understanding the operations. Similarly I'd believe that designing an LLM could require more math. Although in practice I haven't seen any difficult math in LLM research papers yet. It's mostly trial and error and the above linear algebra.

I will charitably interpret “heavy research” as a joke.

It is hard to interpret the smugness above in a positive light. It is unhelpful to you and to everyone here.

If you want to compare an electric car against combustion-engine vehicle, go ahead, but that isn’t a key decision point for what we’re talking about.

The TrueCar web page table does not account for a $7,500 federal tax credit for EVs. I recognize it ends soon — September 30 — if only to head off a potential zinger comment (which would be irrelevant to the overall point).

All in all, it is notable that ~2 minutes asking a modern large language model for various comparisons is more helpful than this conversation with another human (presumably). If we’re going to advocate for the importance of humanity, seems to me like we should start demonstrating that we can at least act like why we deserve it. I view HN primarily as a place to learn and help others, not a place for snarky comments.

A better modern comparison showing less expensive EVs would mention the Nissan Leaf or Chevy Equinox or others. The history is interesting and worth digging into. To mention one aspect: the Leaf had a ~7 year head start but the Tesla caught up in sales by ~2018 and became the best-selling EV — even at a higher price point. So this undermines any claim that Tesla wasn’t doing something right from the POV of customer perception.

I don’t need to “be right” in this particular comment — I welcome corrections — I’m more interested in error correction and learning.

The 12th chapter designates the Genetaldirektörs, Ambassadors, Rikspolischefen, and other government leaders of the executive branch (ie Swedens equivalent of the Commission) as political roles, whose hiring is done by the Regering and the Prime Minister. Regeringsformen also allows the executive branch and their leader to interpret and execute laws. It also allows the executive branches to issue guidance on their interpretation of the law.

You seem to be under the impression that the executive branch in Sweden has no political rulemaking powers when it in fact has been given such according to constitution law.

The “whatever reason” can be to build a portfolio to apply for jobs. Or worse, to more quickly build trust to exploit vulnerable projects.

Baader-Meinhof phenomenon at work; I commented about the ultrasound/handedness the other day.

I wonder whether the political actors in question don't understand correlation != causation, or whether they hope that enough of the populace does not understand it in order to further some goal. But what goal? Buying cheap drug shares? Seems ... silly.

Do they?

Or is it, perhaps, possible that, if there is indeed a real increase in the rate of autism, it's because of something that has nothing to do with our modern pharmaceuticals?

Could it perhaps be related to the increases in various kinds of air pollution? Water pollution? Pesticides or herbicides in our foods? Or even the dramatic increase in EM signals being broadcast everywhere?

Until there are reputable studies that can actually show something resembling a causal link, getting angry at the medical community, pharmaceutical manufacturers, or vaccine makes for saying they are not responsible is pointless and counterproductive. So far as everyone knows, it really wasn't them.

And while there may be some small subset of people "accusing suffering parents of being crazy", by and large that's also not something that's happening.

I have measured it myself within my organization, and I know many peers across companies who have done the same. No, I cannot share the data (I wish I could, truly), but I expect that we will begin to see many of these types of studies emerge before long.

The tools are absolutely useful, but they need to be applied in the right places and they are decided not a silver bullet or general-purpose software engineering tool in the manner that they're being billed at present. We still use them despite our finding, but we use them judiciously and where they actually help.

the city decides things like street parking, minimum parking space requirements, or if you can put up a parking lot, thus deciding the total amount of available space. actual operation of the parking spaces can be offloaded to private entities.

if less space is allocated, it becomes more expensive (scarcity), driving down car use. this is an easy case of pricing in environment and external impacts.

I recently contemplated about a thing: on a galaxy scale, the speed of gravity (or gravity change) should have a somewhat noticeable effect. There's a slight pull towards a star on the other side which is not there anymore for 50000 years! Of course there's some other star in that place, but I wonder how minuscule that effect is. Would it speed up or slow down rotation of outer regions of galaxy?

I still do of course, he should have the self-awareness to have never accepted and it is his massive ego that keeps him doing crazy, dangerous things. But whenever this mentally ill person does things that make the news, I never hear anybody blame the people who put him in that position, and leave him there despite the clearly harmful things he does every day. So shame and blame on everybody involved.

I don’t need self driving cars that can navigate alleys in Florence, Italy and also parkways in New England. Here is what we really need: put transponders into the roadway on freeways and use those for navigation and lane positioning. Then you would be responsible for getting onto the freeway and getting off the exit but can take a nap between. This would be something that would be do e by the DOT, supported by all car makers, and benefit everyone. LIDAR could be used for obstacle detection but not for navigation. And whoever figures out how to do the transponders and land a government contract and get at least one major car manufacturer on board would make bank.

Honest question: did Tesla in the past promise that FSD would be unsupervised? My based-on-nothing memory is that they weren't promising that you wouldn't have to sit in the driver's seat, or that your steering wheel would collect dust. Arguing against myself: they did talk about Teslas going off to park themselves and returning, but that's a fairly limited use case. Maybe in the robotaxi descriptions?

My memory was more that you'd be able to get into (the driver's seat of) your Tesla in downtown Los Angeles, tell it you want to go to the Paris hotel in Vegas, and expect generally not to have to do anything to get there. But not guaranteed nothing.

Yes, bokeh blur is way more pleasing. In my article the gaussian likes are the focus for their use as a basic building block for other effects, like frosted glass, heat distortions, bloom and the like.

Specifically the 2015 Dual Kawase was created in the context of mobile graphics, with weak memory throughput. But even on my RTX 4090, near the fastest consumer hardware available, those unoptimized unseparable, naive gaussian implementations bring it to a crawl and `samplePosMultiplier` has a non insignificant performance hit, so texture caches still play a role.

At today's high resolutions and especially on mobile, we still need smart and optimized algorithms like the dual kawase.

There is room for improvement in inference, hence the presence of various startups in this space and the increased innovation in software. Large nvidia clusters are still cost optimal for scaling inference (as they move most of the memory transfer of smaller setups out of the critical path), and their energy cost is trivial compared to the cost of the hardware, but these conditions may change.

Training is nearly fully compute bound and NVidia/CUDA provide decent abstractions for it. At least for now. We still need new ideas if training is to scale another 10 orders of magnitude in compute, but these ideas may not be practical for another decade.

I don't understand why it's so popular to run the docker daemon as root.

Rootless mode seems to support all the same features, but is obviously more secure than the "run everything as root" mode. In fact, most of the CVE's mentioned would allow an attacker to escalate to the privilege of the user running docker, instead of escalating to he root user.

Comparing the security of rootless-podman to rootful-docker is an absurd (and obviously unfair) comparison.

I think he should try more stuff that aligns more closely with the original purpose of the device, I.e. programmable mixing and "routing" of fluids.

From all the examples with the glass pane, I found those the most interesting.

Maybe connect multiple of those devices together with hoses into some kind of "fluidics network", or build a hyper-exact cocktail mixing machine or something similar.

I just woke up when I saw the submission, and when I scrolled through the comments I saw the one to which I replied because it did provoke me enough (you can even say it triggered me :D) to make such a reply.

I am glad it was a useful read to some at least! Of course if there are mistakes, I expect them to be called out and corrected, it has been a while since I last studied this. :)

I hope I did it right, I was still just waking up, and English is not my first language to begin with, but to see you write this does make me glad I made the comment.

My handwriting was terrible -- until I took a technical drafting course in school. The two things I got out of it that lasted were readable handwriting and better arrowheads on lines, when I remember to do them properly.

Good news: you don't actually have to take a technical drafting course. You just need to find an architectural lettering guide that you like, and practice for about fifteen minutes a day until it feels normal. (Architectural, not ASME. ASME is too rigorous to become anyone's daily handwriting.)

Even though you are right, that misses the point terribly.

It's like using Instagram or Facebook. It's not at all a matter of individual choice when all your friends are on one single platform.

Sure you can host your code anywhere, but by not using GitHub you are potentially missing out on a very vibrant community.

It's all Microsoft to blame. It bought the medium and took an entire community hostage in the process just for the sake of profit.
Show HN: QuickDeploy – Deploy your web app to a VPS with one command
by programonaut | 2025-09-06 12:39:24+00:00
Hi HN, I am Max and I am building QuickDeploy! It lets you deploy web applications of all sorts to your VPS with one command! Here is a little showcase of the tool itself: https://youtu.be/Feauj4OaePg

Under the hood quickdeploy detects the language and framework you use, so e.g. Next.js and then creates a Docker image. After that it starts the container and waits until it is in a healthy state before using a reverse proxy to redirect traffic to the app. Added benefit is the use of your own domain with instant https!

I am super happy with the result and the ease of use. After it is configured once it just works with one command, that's so cool! Hopefully it will enable more developers to host their own apps and get them interested in that kind of stuf..

Would love your feedback on the tool!

Oh it won't take long if some company with deep pockets wants out of this. An 'exemption category' will be quietly put in and those who paid the right people will qualify. This is Trumpinomics now at the state level; put out harsh new rules and then let people pay you off to get exempted from them.

So humans lost the fur to outcompete other animals through superior evaporative cooling. No big deal because we're all in Africa.

Then we moved north and did not get enough sunlight anymore for metabolic processes. Easy solution, we just turn white.

Now we are both freezing and getting sunburnt at the same time. Evolution sucks, we should have kept the fur.

Paracetamol/acetaminophen (the active ingredient in tylenol) is super toxic to the liver. Lots of people overdose on it, some by accident and some deliberately. As little as FOUR GRAMS can cause jaundice and fuck up your liver. If you have a fever, taking 1 gram every couple of hours might seem entirely reasonable, but it can kill you.

Regardless of any autism links, it's good to be careful with this stuff.

These are technical details of computations that are performed as part of LLMs.

Completely pointless to anyone who is not writing the lowest level ML libraries (so basically everyone). This does now help anyone understand how LLMs actually work.

I assume HLL=Higher Level Language? Mojo definitely avails lower-level facilities than Python. Chris has even described Mojo as "syntactic sugar over MLIR". (For example, the native integer type is defined in library code as a struct).

> Whether it's 1, 2, or N kernels is irrelevant.

Not sure what you mean here. But new kernels are written all the time (flash-attn is a great example). One can't do that in plain Python. E.g., flash-attn was originally written in C++ CUDA, and now in Triton.

That's blaming the victim. The vast majority of the opensource projects were hosted on GH since before Microsoft's acquisition.

Hyundai is investigating 12.6 billion dollars in Georgia, and the response is to raid the facility and arrest ~500 people working there. How does that benefit Americans? Korea is pumping money into our economy, and we throw the people working there in jail. For what? Working?

If Hyundai's operations keep getting disrupted, they can't justify spending billions here. Other international companies also won't waste their time investing and building infrastructure here. They'll spend it somewhere else. What is pro-American about this? Is the Republican party now anti-money? Anti-capitalism? How is this a win for Americans or Republicans or conservatives or anyone?
