There are legitimate reasons for such a thing though, I think. Like I don't want my juice dispenser to do general purpose computation. I don't want it to be capable of web surfing.

Ideally you would do that by building it out of simple mechanical components, but if taking smart components and dumbing them down is cheaper then that sounds fine too.

You need to be doing enterprise sales not marketing. There is a lot of advice here and in general on that but you definitely need to be making calls with that type of business.
Why would anyone think it is official when there is nothing indicating that on the image in question? To know that it is "official", as opposed to something which was just drawn to illustrate the article, you have to remember that it came from a nasa slide deck.

The article clearly makes the point that nobody seems to know how many Starship launches the lunar mission will take. It varies from 4 launches (by Elon) to high teens (by Lakiesha Hawkins) and 15 (by Kathy Lueders).

If you don't recognise the source of the original image then it just illustrates the text of the article. No harm, no foul. If you are so much into inside baseball that you recognise the resemblance to the nasa slide then you get the additional meaning: the plan changed. Not even the diagrammatic "concept of operations" is fixed properly here.
But training just allows it to replicate what it's seen. It can't reason so I'm not surprised it goes down a rabbit hole.

I've thought the better idea would be to tune the laser beam to resonantly scatter off certain ions that are kept trapped in a magnetic field.

Singly ionized alkaline earth elements (magnesium, calcium) should have very strong resonant absorption, just like neutral sodium, due to the single outer shell electron. If the laser is tuned properly it could even cool the ions, preferentially scattering off ions moving toward the laser beam, reducing their kinetic energy in the rest frame of the vehicle.

The idea of laser cooling might also apply to a solid laser sail.

> "Why would it not work?"

As a thought experiment I'll go with "atom by atom replacement would still be you". But I won't easily go with "therefore we modern humans could actually do it in reality, and replace the parts with fakes, and then with simulated fakes, and then extract the simulation to run elsewhere for the uploading part, and even God couldn't tell the difference" just by asserting all those extra bits to be true. When have we ever made perfect replicas with the inside the same, of anything non-trivial at any scale?

Physical impossibility (it would work but we can't do it) argument, see here for long discussion of how hard the engineering problems of just Neuralink are: https://waitbutwhy.com/2017/04/neuralink.html

Physical "doesn't make sense" argument; we model brains as 80 billion neurons but bodies are not neatly separate organs and neatly separate pieces. The brain isn't separate from the body - nerves are basically brain matter spreading down to your spine, guts, arms, legs. Are 80 billion fake neurons surrounded by layers of scar-tissue reconnections going to be the same? What sense does it make to suggest a simulated sperm could mate with a real egg?

Show HN: Built a Telegram Bot to Simplify Digital Journaling in a Weekend
Hi HN,

I recently developed a Telegram bot to simplify digital journaling, and I’d love to get your feedback. The bot supports both text and voice messages and includes features like:

- Voice Transcription (using OpenAI Whisper)
- Automated Reminders
- Word Cloud Generation
- Similarity Detection (using ML)
- Historical Journal Viewing

You can try it out here: https://t.me/JournalCompanionBot

I built this in a weekend and am eager for your thoughts. What features do you think would make it better? Have you encountered any issues? Do you think this could evolve into a subscription model?

Thanks!

>I know advertisements are a thing for YT, but is it enough?

Google uses search revenues to subsidize the cost of YT. It's anti-trust, but the government hasn't had the will to prosecute as of yet.

I think YT is finally self sufficient, but probably still relies on google's existing infrastructure to a large degree to keep costs down.
I WISH it would be prefetching video in background while showing ads.

But no, always goes to spinny wheel buffering after ad ends. Oh, and thats after having some spinny wheel to load the ad in first place ffs.
And it wouldn't be a (small) fraction of the cost of a DT fusion power plant.

The NSS, nuclear steam supply system, is estimated by the following link to be 12% of the cost of a NPP.

https://world-nuclear.org/information-library/economic-aspec...

So, a fusion reactor an order of magnitude more expensive would double the cost of the entire power plant.
With a disclaimer that I have no formal nor practical background in marketing, here are some ideas:

1. It is a bit unclear to me when I would use Haystack. The main advantage seems to be cost cutting. It would be nice to see some realized examples of this.

2. When competing for price, you may look like the cheap, and thereby untrusted alternative. There is a risky business paradox here, for which I am sure a fellow HN poster will supply the name: you charge less, therefore you make less, and you will not be able to sustain the service, making me not want to spend money.

3. Have you tried looking for companies that may actually need this solution? Have you tried contacting them directly?
Also Boeing, North American and Douglas built the Saturn V.
It would be illuminating if you showed an example of what you mean by using modulo arithmetic, or getting the delta; otherwise we can't comment on your idea.

Otherwise we are talking about feelings and hunches.
Yes, and hardware support for encrypted RAM already exists:

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

However, this will never be perfectly secure against backdoored RAM in a multitasking environment, because the memory access patterns alone leak information. Additionally, I don't think any of these systems support authenticated encryption, which means you could do things like corrupt branch targets and hope to land on a big NOP slide you control.
You might even have a few more.

Eg you might have a record for each stage of the meal. When it's ordered, when it's cooked, when it's delivered, etc.

Show HN: Is Your Website Any Good? Instant AI-Customer Feedback for Any Website
Hey HN! I built TestMyWebsite - it analyzes your website's content and tells you - in a nutshell - if your website is "any good".

Startups and bigger companies alike often struggle with getting their point across in a clear and relevant way. The result is corporate gibberish and generic-sounding marketing blah with zero relevance to the target customer.

TestMyWebsite is your sounding board to make sure you don't fall into that trap.

I frequently use website testing tools such as GTMetrix, but they only analyze the speed and technical aspects of my website. This app will analyze the content from your target audience's perspective to understand if it's clear, relevant, and well-written, and come up with improvement tips.

Feedback so far has only been from friends & family, so I'm very curious to see if the app provides value to the HN community. It currently works best for homepages, but I'm considering expanding it to landing pages, ad campaigns, eCommerce pages, etc., if there is a need.
One of the problems is that return types and exception types are not unified so it makes composition harder. `Result` brings exceptions into the regular type system
You have to give up your preconceptions and "think outside the box" as it were. Think of Nihilism as the canvas background against which you paint your chosen philosophy/religion/beliefs. Life "objectively" (i.e. from outside in) is meaningless (applying Occam's razor) but lived "experientially and subjectively" craves meaning. You have to keep both these distinct and separate viewpoints simultaneously in mind while treading your own path. Modern Science has so advanced our objective understanding of the world and ourselves that we can no longer cling to beliefs from the past unconditionally (eg. organized religion) without validating and re-interpreting them in the current context.

Here some of the Hindu schools of philosophy are of great help since many(eg. Carvaka/Samkhya/Yoga/Buddhism/etc.) don't subscribe to the idea of a omniscient "God" but merely construct a experiential worldview based on perception and inference. It is like a mathematical formal system with concepts/symbols/rules/etc.
Sure, sure

For that to work, they don't have to be ancient. Just fit enough long enough to be too much of a net burden to the younger generations. The menopause seems to coincide with the age where people used to become grandparents.

Furthermore, people getting too old might make it harder for collective cultural knowledge to evolve. Which is fine in good times, but disadvantageous in volatile circumstances.
My most replayed game is Traffic Department 2192, as much to re-experience the 70,000 words of script as anything else (it became freeware a while back, and I'd endorse anybody reading this firing up your DOSBOX to try the first mission - if it's your sort of thing, the dialogue will almost certainly hook you by the time you're ready for the second).

It's at least 25 years since I first played it now and I'm always pumped to replay it.

Because of better and easier to prove legal definitions. It's not about the lack of competition, but just the number of users you have.
Why won't anyone in financial services define "AI"?
There's definitely scientific insight and analysis.

E.g. "In-context Learning and Induction Heads" is an excellent paper.

Another paper ("ROME") https://arxiv.org/abs/2202.05262 formulates hypothesis over how these models store information, and provide experimental evidence.

The thing is, a 3-layer MLP is basically an associative memory + a bit of compute. People understand that if you stack enough of them you can compute or memorize pretty much anything.

Attention provides information routing. Again, that is pretty well-understood.

The rest is basically finding an optimal trade-off. These trade-off are based on insights based on experimental data.

So this architecture is not so much accidental as it is general.

Specific representations used by MLPs are poorly understood, but there's definitely a progress on understanding them from first principles by building specialized models.
Don't they simply use ffmpeg for that?
I would agree putting a cartoon character in readme, without any good context is definitely unprofessional. But would not go as far as offputting.
Show HN: My preparation before scaling up my product
Hello HN,
I'm Rully, an Indie maker who loves to build something. I wanna share my little story from one of my products.

a little story, a long time ago before I'm know and using VPS. I'm using Shared Hosting for my hobby and small business. But, the problem was:
1. I can't get hosting with unlimited bandwidth
2. It's not easy to find a hosting provider that supports NodeJS, Ruby, Python, and other services in 1 bundle
3. Usually, when point 2 is achieved. The price is too high and I can't afford it.

So, that's the reason why I'm launching JustAHost. What is next? Scaling up by adding more server locations.

The first serve location was in USA. Then, slowly but surely I can add more server locations to cover up my client's needs, especially for Europe that has GDPR regulation.

Before I do that, I don't wanna take a rush. I wanna make sure I can implement the same features and services for all regions. So, I'm starting by creating a boilerplate/framework/architecture to achieve this.

Then, I can safely add more server locations. And now, I've 7 server locations with the same features, benefits, and services.

Cheers,
- Rully
1. What you're describing seems to be a criminally underfunded universal healthcare. In properly funded ones, you aren't limited to one or two visits to a doctor a year.

2. Public healthcare does not prohibit people from using private doctors. People who can afford to go to the private doctor can still do it. Whereas people who can't (or can, but just choose not to), get their lifes saved by the state.

3. Profit motive is deeply flawed in all businesses, but it's especially problematic in something as critical as healthcare. If the doctors are primarily driven by money and not by doing their job properly, they'll fleece their customers. It's not uncommon among dentists (who are largely privatised even across Europe) to make up expensive, unnecessary procedures so that they can buy their next Porsche or a house on the Spanish coast etc.

Great write up! I worked for a few months at a Google datacenter and a few times got to see the fiber endpoints.

Though the idea of such networks not being sold on the market makes be ponder if starlink will come to provide such a service. They’d need to scale out their laser links and ground stations.

Makes you wonder what went differently that one time. Does the body say produce immune cells with some level of natural variation and that one time it happened to produce ones sensitive to the substance?
Yes, that's the philosophy around the declaration syntax.

The declaration of the pointer ip,

int *ip;

is intended as a mnemonic; it says that the expression *ip is an int. The syntax of the declaration for a variable mimics the syntax of expressions in which the variable might appear. This reasoning applies to function declarations as well.

Is this another outlier when you reach certain scale, it’s more beneficial to roll your own? Pretty amazing what Uber has to deal with.

Also it’s not very clear from the original articles, what is the new total “cost of ownership” of this new refactored service. Like now they need to manage their own databases and the storage backing them. Or did i miss it?

This might be an interesting reason for it to feel special, but I'm not entirely convinced, and I probably don't fully understand what you mean.

It seems that not everyone values the having of a consciousness as something special. Survival works pretty well with a good appetite, some muscle for clobbering enemies, and a good sex drive. How does (thinking about) consciousness add an advantage here?

Yes, on the last flight both the first and second stages had no problems with the engines on ascent. If this were a Saturn V booster, it would have been a complete success. They did suffer failures with booster recovery, and with the RCS in orbit, but controlling large numbers of small powerful cheap engines seems to be a solved problem already.

From the Show HN rules:

> Please make it easy for users to try your thing out, ideally without barriers such as signups or emails

Also, having a demo on your landing page that asks a user to fill out a bunch of stuff and only after that demands an email address in order to see the results is a very annoying dark pattern. Be up front with the data you're requiring to use your tool.
I don't know why this is such a hot take.

Personally, I find it distracting when some devs start to "spice up" their presentation with manga characters, furry characters, memes, or whatever stuff they enjoy.

Shit, I love Zelda - but I wouldn't want Link all over my presentations. It just looks...juvenile and unprofessional. Doesn't mater if you're a beginner or world leading researcher, just keep it simple and undistracting.

EDIT: That said, I'm probably not the intended audience for this piece.
One observation I have regarding your homepage is that the message isn't very clear. The headline doesn't mention any benefits I get from using your software.

I think you should invest some time into improving your landing page and maybe you may see some traction. A good resource for this which I've bookmarked is here(1). Hope that helps.
