Hi HN,

I’m the creator of AI Diagram Maker — a tool that helps developers instantly create architecture diagrams, flowcharts, and sequence diagrams just by describing them in plain English.

You type something like:

“User logs in → system validates credentials → show dashboard”

and it automatically generates a clean, editable diagram using the D2 diagram-as-code format under the hood.

No drag-and-drop, no manual layout tweaking. You can edit the generated diagram, export it, or refine it further with natural-language commands like “make this a sequence diagram” or “add a database node between API and UI.”

I created this because we can now leverage the power of LLMs to make diagram creation as productive and intuitive as vibe coding — while avoiding the usual pain points of traditional diagramming tools.

I’d love honest feedback from the community: • Is this something you’d actually use? • What’s missing or frustrating? • How can this be more useful for real-world dev/design workflows?

Appreciate any thoughts, critiques, or suggestions — good or bad.

Writing assembly is tedious. It takes time and a lot of care. Sometimes it is necessary, e.g. writing certain parts of an OS.

Almost always it involves carefully reading documentation, triple checking everything, mentally imagining the state of the processor, especially concerning whether interrupts can occur or what they would cause.

Having done it a couple of times I, for the first time, really appreciated the abstraction of e.g. C. It made writing code and reasoning about it a lot easier. To be honest, I really dislike the mystique it gets in some circles. In the end it is just another programming language, which just consist of many very small details and limited abstractions.

What I have no doubt about, is that abstractions around Assembly will continue to exist. Maybe LLMs will be really good at writing high performance assembly, but still it will not be something humans really interact with.

Your own stats actually seems to suggest otherwise, doesn’t it? About 1 in 5 murders of white people are committed by blacks, while about 1 in 10 murders of black people are committed by whites. And in absolute numbers there are slightly more black murderers.

Arguably race is the wrong metric anyway, isn’t it fairly well established that socioeconomic factors play the larger role by far?

Two things, in the spirit of answering your question and explaining myself.

1. The argument above is sound, but it overstretches my metaphor and sidesteps my point which is: "if there is negligible cost in helping a customer, do it." Stated another way: "if reducing ambiguity helps a customer and has negligible cost, do it." (If a one word change reduces some ambiguity for some people, that's an easy win. Copy-editors do this frequently.)

2. Another angle: broadly speaking, I'm asking the question "What is better?" not just "What is necessary?". The first motivates improvement, no matter where you are. While the latter can sometimes be pragmatic, too often aiming only for 'necessity' justifies the status quo.

This is good advice. The breakdown really depends on how big of a gap there is between the reality of your product and your "live-looking" demo. Also, the stakes matter here as well. You can end up in Magic Leap territory pretty quickly, and it is telling that many people might not even understand this reference. In general, I totally agree with the OP, especially for a talk. However, the Meta demo likely failed because the technology was simply not fully there yet. Add in thoughtless executives and a marketing team, and you can be doing a live looking demo of something that absolutely does not exist. You will then be ripped apart by the press and your users taking a massive reputational hit.

Yeah, these monitors were a bit heavier than most consumer 21" monitors at the time. We also got Viewsonic monitors for PCs, which were lighter. At the time, I had assumed the additional weight was from extra shielding, but I later read that some of the weight difference was a metal frame holding the wires. The trinitron had a bunch of vertical wires instead of a grid of holes on the front - If I remember right, they'd shimmer a little if you smacked the side of the monitor with your hand.

It's possible they also had more glass than typical for a 21" monitor, I don't recall if they were any flatter than the Viewsonics or not.

I ran a SaaS for 10 years. Two products. Profitable from day 1 as customers paid $500/month and it ran on a couple of EC2 instances as well as a small RDS database.

Another thing one has to consider is the market size and timeframe window of your SaaS. No sense in building for scalability if the business opportunity is only 100 customers and only for a few years.

It's the same with the GDPR...

But note that merely being accessible in the UK is not enough here. The service must either target the UK or have a significant number of users in the UK, or it provides harmful content. So the online forum for Oregon gardeners is quite safe even if, indeed, accessible from the UK.

But still it is an awkward legislation and it would be simpler to simply block rather than to threaten and fine services from around the world.

> I couldn't care less if someone wants to spend the time and effort to intercept and change pages from a blog I read.

I do not understand why so many people think having, say, zero-day exploits served to them is not a problem.

The blog is not the target; the unsecured connection is.

Approximately nobody is taking the time to hand craft a specific modification of some random blog. They develop and use tools that manipulate any packet streams which allow tampering, without the slightest concern for how (un-)important the source of those packets is.

For this form factor it will be likely ~2 years for the next one based on Vera CPU and whatever GPU. The 50W CPU will probably improve power efficiency.

If SOCAMM2 is used it will still probably be at most near the range of 512/768 GB/s bandwidth, unless LPDDR6X / LPDDR7X or SOCAMM2 is that much better, SOCAMM on the DGX Station is just 384 GB/s w/ LPDDR5X.

Form factor will be neutered for the near future, but will probably retain the highest compute for the form factor.

The only way there will be a difference is if Intel or AMD pump their foot on the gas, which this makes maybe 2/3 years of it, with another 2 years unless they have something cooking it isn't going to happen.

Ah cool, thanks for that!

Oh man, that was about 3 lifetimes ago. I'm on linkedin (every couple months hah) if you ever want to chat.

It was a fun project, but we released it just in time for the Dot Bomb to wipe us out. Our last month, my partner and I got about $600 each from shareware game sales ($1200 with inflation today), enough to pay rent and my student loans for the first time. After the pop, the next month we got one sale. $12. The fun was over and never came back in the same way.

The powers that be conspired to end the 90s climb towards FU money and UBI, and there was no tech investment for about 6-7 years until 2007 when the iPhone and Facebook came out, which started the mobile bubble. Lots of people made $100k those first years, but mostly not established players, who had too much time, effort and money sunk into the old desktop platforms.

Then Google and Facebook took the lion's share of ad money, which removed the avenues to scale a business. Everyone moved into other models like in-game ads, in-app purchases and going viral through influencers, but none of those worked for the vast majority. To leave us where we are today, where long tail effects ensure a winner-take-all sales distribution.

Now that AI is here, even apps will begin disappearing. I predict that within 3 years, nobody will be using the web or buying software anymore. We'll just ask the AI to do everything, and it will make it so. Thus ends the mobile bubble too.

I basically missed every bubble due to unfortunate life choices. So let this be a cautionary tale to any young people who read this. You need to do the opposite of what people say. Nobody gets rich pulling themselves up by their bootstraps, they get rich by borrowing someone else's money and investing it in sure things like Bitcoin 15 years ago. If you feel yourself clinging to a project or situation because you have a lot invested in it or don't want to let someone down, that's the time to explore other options. You won't make yourself poor - your empathy will. That's why the rich demonize it. But empathy is where the true meaning in life is found. You can choose to skim money off other people's backs through investment, or "earn" it yourself, but there is a karmic cost no matter how you obtain it. So just have fun and do your best and at least pay your taxes so that society can progress forward, or we'll never stop repeating these systems of control and suffering IMHO.

When I was making Retro, I was trying to capture the feeling of the golden age of arcade video games, even if I maybe missed the mark. But I didn't realize that I was in a golden age at the time. I believe that we're in one of those now, maybe the last one. But also the first one, from a certain perspective.

Maybe it's time to dust off the old compiler and make a game..

Yeah, that's totally believable. I remember how everyone raved about cheap EV charging a decade ago, how it would save costs etc. And today a commercial fast DC changing is more expensive (per km of range) than an ICE car of the same class and size. And that's with gas prices doubling since 2009 crash. I've just did a quick calculation with today's prices and modern cars in the comparison.

> However, paying dividends is a taxable event, which means shareholders don't like it.

Shareholders love dividends because it is taxed as capital gains ( long-term capital gains if you own the stock longer than 1 year ). It's why most of the publicly listed stock ( of profitable companies ) pay dividends - because shareholders want dividends. Apple was forced to pay dividends by investors. So was Meta. As was Alphabet. All under shareholder pressure because dividends get tax as capital gains. Any company sitting on a pile of cash will get pressure to pay it out as dividends by shareholders.

I myself post positive comments about AI from time to time.

I never pretend that AI is the be all end all of programming, don't claim that it can do all the magical things, or that it's capable of running hours on end just creating software with not proof like most positive posts do.

See the difference?

I'm all for positive posts. I'm against childish belief in magic: https://dmitriid.com/everything-around-llms-is-still-magical...

most of this research is fake you know.

For example this was going around for a long time:

https://www.brennancenter.org/our-work/analysis-opinion/debu...

Then this happened in 2025 when there was a crack-down on crime:

https://counciloncj.org/crime-trends-in-u-s-cities-mid-year-...

Also, 1% of the population is responsible for most of the crime

https://pmc.ncbi.nlm.nih.gov/articles/PMC3969807/

So if you end up jailing people, the crime just goes down.

Also, then if that's true, then cancel all murder prison sentences!

Yes, CT makes any sort of certificate issuance attack relatively "loud", but as you seem to be aware that doesn't actually stop the attack from happening in the first place unless the attacker cares about keeping it a secret.

This isn't like a missisuance where you can blame the CA and remove them from the root stores; they'd just be following the normal domain validation processes prescribed in the BRs.

Actually, scalability is cheap. Our AWS bill until recently was around $160-$200 a month. To get the level of HA and performance would require at least 20 boxes in two data centers.

Dev/test/prod with an HA db and a backend that never dies. I’ve built those on bare iron and they’re expensive.

If you’re going for saas and customers that don’t care about your infrastructure then a hetzner box is fine.

But really, creating resilient infrastructure is super cheap now.

Agree with “make what your customers want,” but many customers actually want a service that doesn’t barf.

I think a lot of people conflate "built to last" with "ability to be repaired by yourself."

To continue the car analogy, I could replace almost any part easily, with simple tools I have at home, on my 1990 GMC 1500 truck. Parts are plentiful and cheap, plenty of room to work on the engine, nothing is hidden inside black boxes. It's got 280k miles on it and still running great.

To contrast that with my 2020 Subaru Crosstrek hybrid, is much more difficult to work on, can't even fit my hands to access anything that's not on the top of the engine, other repairs requiring full engine removal and specialized tools. There's more electronics and more completely sealed systems.

Same can be said about some household appliances, and even computers. Not only were things, generally more repairable, but repair didn't require specialized tools in most cases, we didn't have to first melt glue, resolder SSDs, etc.

My old compaq Armada may not have been built to last at the time, but it was certainly stupid easy to repair and replace every single component in it.

The thing is, we've already had "working mockup generators" — a.k.a. prototyping tools — for decades now.

If you come at the problem from the direction of "I draw a user interface; you guess what it's supposed to do and wire it up for me", then all you need to solve that problem (to a first-order approximation) is some plain-old 1970s "AI" heuristics.

The buzz around current AI coding prompting seems to be solely generated by the fact that while prototyping tools require you to at least have some training as a designer (i.e. understanding the problem you're solving on the level of inputs and outputs), these tools allow people with no experience in programming or design to get results. (Mainly by doing for UIs what genAI image/video tools do for art: interpolating the average of many ingested examples of how a designer would respond to a client request for X, with no regard for the designer's personal style†.)

† Unless prompted to have such regard... but if you know enough to tell the AI how to design everything, then you may as well just design everything. Just as, if you know art well enough to prompt an AI into developing a unique art style, then you likely know art well enough to just make that same art yourself with less effort than it takes to prompt and re-prompt and patch-erase-infill-prompt the AI into drawing what you want.

Full disclosure: I am part of the Triljon team, but we are so exited to start sharing the news.

This is a major milestone for us. But more than that, starting today, investors who fuel visionaries can expand their opportunities while reclaiming their time. This marks the first of many products we’ll release as part of our ongoing mission to make doing business "easier".

In a Triljon future, anyone bold enough to commit to their idea has a real chance of making it happen. No red tape, outdated ways of working, or bureaucracy getting in the way.

Because every time innovation is slowed down by old systems, we risk losing the next iPhone, lifesaving vaccine, AI breakthrough, or whatever the next big thing may be. We can’t afford that.

It won’t happen overnight. But with the right people, mindset, and problems to solve, we’re building a future where the hardest parts of starting, running, and scaling a business fade away, replaced by the Triljon ecosystem.

We’re building tools that accelerate innovation for every business, entrepreneur, and investor.

Solar is extremely cheap and battery costs are dropping quickly, IMO you may see US neighborhoods, especially rural disconnecting from the grid and rolling their own solutions.

This china rare earth thing may slow down the battery price drop somewhat but not for long because plenty of chemistries don't rely on rare earths, and there will soon be plenty of old EV packs that have some life left in them as part of grid storage.

You're thinking on an individual level. What happens at a societal level. Crime goes down!

Also, an accident is if a party had fireworks and the fire got out of control. Arson is definitely not an accident if someone dies.

Regarding "people change" argument. I'm not advocating for the death penalty. I'm advocating that we separate non-civil and civil society. If that takes the shape of the next Australia? Sure, then if someone changes, they're not in jail.

I'm also not advocating for someone non-violently stealing bread to be separated from society. Those people can change.

Someone that at one moment of their life decides that someone else's is worthless because they want the contents of a cash register? Remove them from civil society.

I appreciate the information! And yes, the fact that most sites are corporate makes me really distrustful of running random scripts from them.

This is sort of an example of what I'm talking about though, this script seems to install a bunch of random stuff but what I really want is an API to incorporate into our own recording process. As far as I can tell from a brief look, this binary (?) is downloaded from somewhere and run: https://github.com/airplanes-live/feed/blob/main/scripts/air... but I just want to incorporate it in the system we're using already when I finally get to improving it from a 10-minute hack job from when I set it up as a side project that ended up being really useful (https://arxiv.org/abs/2506.17522)

which doesn't "interact" with normal ("baryonic") matter

I think you mean it doesn't interact electromagnetically with either matter or radiation. It does interact with normal matter via gravity -- that's pretty much the strongest (only?) argument for its existence.

I'm not aware of any reason this object can't end up being a giant sphere

AIUI, most theories posit that solid spheres of dark matter are very unlikely because matter accretion is governed by electromagnetism in addition to gravity, and dark matter is not supposed to obey the former. Most models assume that dark matter is organized in gaseous clouds (halos); strictly speaking that's still a giant sphere, just not in the same way that Jupiter or the Sun or even the Oort Cloud is.

I was always surprised that when we talk about BHs mass, charge, and spin that we really mean U(1) (electromagnetic) gauge charge and not charges from global symmetries. (If BHs had global charge, you could at least say that this or that black hole was made out of N baryons, or whatever.)

But it's really so---according to GR, black holes don't have global charges. So even if you see a star made out of baryons collapse into a black hole, once the BH settles down into a steady state you can't say it's "really" got baryons inside: the baryon number gets destroyed.

(Of course, a different model of gravity that preserves unitarity might upset this understanding.)

It's that it demonstrates that some sort of noumenon can likely have partial but not 'full' overlap as we understand it with a phenomenon.

To elaborate, the noumenon can have properties that are unknown to us and outside the purview of certain senses (if not all) but still have partial phenomenal effects such as gravitational effects.

Given partial overlap, we could, and likely should, surmise that overlap, if partial, can also be zero. In fact, partial overlap with certain things (such as the gravitational field) but no sensory experience is exactly what we'd predict if this were true.

The mistake is thinking I'm asserting that things are phenomenon or noumenon when that's not quite right. Mostly, the supposition is that things can exist and have either 'full' (unlikely I think), partial, or zero overlap with our sensory experience. Things that demonstrably have partial overlap suggest a wider world of things. I simply find the idea that our evolved sensory experience encompass even a sizable fraction of reality to lack epistemic humility.

This is obviously speculative.

This opinion is always so funny to me. Sometimes HN is afraid to judge someone on-grounds, other times they're afraid to draw conclusions that might make them look bad.

Apple: "Nobody knows exactly how it's ran, but it's preeminently clear that Steve Jobs was a true MBA and had an almost perfect track record."

Tesla: "Nobody knows exactly how it's ran, but we can say for sure it's probably not the social media edgelord/ketamine addict doing a bang-up job."

This website is quite comfortable and unpretentious.

It solves a few practical needs: helping you keep track of your money, providing price alerts, and summarizing important news. Without those intimidating, complex charts, you can easily find what you need at a glance.

It's like a quiet and reliable companion, providing the information you need when you need it without causing any hassle.

It's perfect for those who simply want to track cryptocurrencies without the hassle of fuss.

Oh shit, I wasn't expecting you to be serious about it.

Well, in that case, I need some sources. For example, I'm not convinced that people project on social media to the extent that you're implying they do. It's a statement that needs support (which you didn't provided).

I am confident that you are able to find those sources, then we'll be able to talk about it on a common ground!
