Show HN: Rocket Launch GenAI – A starter kit to build full-stack GenAI apps
Hey HN

I built a full-stack codebase to help developers create their own GenAI products — with control over backend, pipelines, and LLM integrations.

It includes:
- FastAPI backend with document processing, pipelines, and OpenAI support
- Next.js frontend with auth, chat interface, and analytics
- PostgreSQL + pgvector for semantic search
- Self-hostable with Docker or deploy on Railway/Vercel

Ideal for:
- AI consultants
- Indie hackers
- Dev teams building internal tools

Try it out: https://www.rocketlaunchgenai.com/

Would love your feedback!
There are great developers in India, but they get a lot more than 25% of US salaries. Great developers in Germany are cheaper than India - but labor rules in Germany are weird.
How does it compare to https://wisprflow.ai ?

btw, grats!
> And as far as I'm aware, that process was followed following Biden's announcement.

This is exactly the problem. The Democratic Party excuse is always "we're following the process". The results suck and then they wring their hands wondering how they lost the election. The goal should be to get power, and getting power requires nominating someone popular. Anyone who has paid attention to US politics for the last decade could have explained just how unpopular Kamala Harris would be.
This is an issue I face- I have a collection of thermal cameras that use apps to control them- after every install onto a phone, they then reach out t oa server to authenticate.

Here's the issue- though I have a few older phones- these apps are 32 bit ones, so no modern phone after Android 13 will run them. And they are all now not on the app store anymore,as they all came out about around 2016. i did use a APK extractor to pull the APKs to store them - but the native backup functionality wouldn't capture that authorization in the future, I might rob myself of my ability to use some extremely expensive, and long-term invested capable hardware, by backing up and restoring-

I suspect a full image would solve this problem, but I don't think one can do that outside of things like TWRP- but that requires unlocking the bootloader, and if you do that it wipes your device- AND is more vulnerable to Custom's usage of Cellebrite and etc, to my undertanding.

I don't have this issue with laptops ,as I can fully image them and wipe and restore ahavend have a perfect replica/ no issues. But my thermal cameras do not run off of PC and th eform factor wouldn't work if they did
They also tend to have higher fees and a smaller return than managing it yourself with index funds and bonds. But for people that don't want to do that it is a good option none the less.
This feels like very old-school java client/server architectures.

>This means that you can write your entire application in a single language and deploy it as a single binary. No more microservices, no more containers, no more Kubernetes, no more Docker, no more VMs, no more DevOps, no more infrastructure, no more ops, no more servers.

This is an abstraction layer that will end up being applied on top of most or all of those technologies. You can't hide from the fact that the database instances need to run on something.
Sorry to hear this happened to you.

It's yet another reason I don't use Amazon. Sure, I might pay more for what I buy but I don't need to worry about my information being shared or sold by a giant of surveillance capitalism.
The one thing I had to do is ask for a References section at the end of the research. You can then take that and go through it to check things.
Nice idea but the results weren't comprehensive for the book I tested. I find that chatgpt with web search enabled does a better job with the simple prompt "Create a relationship diagram for the characters in <BOOK TITLE> using mermaidjs. Include the relationships between people."
Show HN: I built a platform to change models and prompts with no deploys
Hey HN!

My cofounder and I built a platform for integrating AI, this means you can change prompts, models, settings, on the fly
Some other cool stuff is that it's a single API/bill/spec for any model may you want to run, all in a single API key

I like to think of it as if vercel's ai sdk turned into a service

Now that I mentioned it, whats the itzam's difference from other AI provider wrappers?

Itzam's main goal is to make it easy to have great AI in your product, meaning two things:
- Empower both tech and non-tech people to refine AI models behaviour, so things like ease of use and learning curves are always in our mind. We want to be as batteries included as possible, while still allowing for customizations to experienced users. This mindset defines our initial target users, teams with managers who need to keep improving their AIs but are slowing the dev cycle with their change requests.
- Switching to a better model should be effortless. Right now we are at the brink of google's gemini 2.5 flash release, if it's viably cheap and reasonably fast, a lot of people we'll want to move from models like gpt4o mini and claude 3.5 haiku, but what do you do if you invested time into creating embeddings and adding context into OpenAI or Anthropic's ecosystem? You're going to have to do it all over again, and that's what we want to avoid. Imagine being able to drag and drop files, links, images and having it shared across AI providers.

Would be nice to hear you feedback!

api + lobechat has been stellar for me
No. Honest answer.
Very true. That said, I've been taking 5000IU daily for the last couple years after a blood test showed my levels were a bit low. As of last week, my 25-Hydroxy D level is 76, near the middle of the 30-100 normal range.

Everyone's different: what's right for me isn't right for you. I just mean that to demonstrate that it's possible for some healthy adults to take a pretty significant amount every single day and have perfectly reasonable blood levels.
Bubble sort is not robust either (2024)
> Maybe it was the deficit outlook, maybe the global response to tariffs

Or, maybe, and hear me out on this, maybe it was Donald Trump literally saying he might default on US debt.

Maybe.
What I don't understand is why other countries didn't make the threat to make any tariffs hold for a year or longer. That would scare Trump away from doing these stupid experiments.
I think you’re projecting more advanced thinking here than you can give them credit for. The administration doesn’t have military guys keeping discipline.

You have Trump who has an instinctive affinity for tariffs, and a wack pack of various characters doing whatever. I’d guess they thought the Chinese would roll over rather that start dumping bonds.
Weird how in the massive "buy stuff from ali and resell" industry nobody has gotten the idea to go to 420% markup and undercut all the competition yet, if its all arbitrary markup.
Dollar stores are generally more expensive in the long run than other stores. They make their money on higher per unit margins and/or vastly lower quality of products.
Yesterday your vice president referred to the Chinese as "peasants".
I am in a similar pickle.

Nobody said CF needs to subsidize every customer. The rules need to be clear though, not secret. Same with anthropic's usage limits, since they're not public they can degrade the service you're paying for at any point in time with no notice.
Show HN: LLM Based Spark Profiler
Hey HN,

Spark event logs run into 100s of MBs and offer a wealth of insight into your workloads but making sense of them has always been quite a bit prohibitive. We’ve recently built a lightweight tool that automatically parses Spark event logs and surfaces targeted insights to help you optimize your data jobs.

Whether you’re chasing down a bottleneck or balancing performance vs. cost, the profiler got you covered with real-time configuration recommendations, data skew analysis, and more.

Curious how it works in action? Check out this quick Loom video for a walk-through: https://www.loom.com/share/07348eb54f6b440da93f96753937792a?...

We’d love your feedback — check it out at https://app.datasre.ai and let us know what you think!
What is the story of the 'letter carrier'?
Yeah, but I think with a government-initiated program, it's going to be a lot cheaper because of the scale. It definitely doesn't solve the problem of corruption or other political issues, but hopefully UBI creates better citizens (for a start, now whoever wants to participate in politics have the time to do more research and participate more) so that those issues get called out.
They were, but they've shown that they'll gladly ignore human rights abuses and autocracy so long as the price is right. Trump's used to doing business that way, unfortunately.

Really, if Putin hadn't invaded Ukraine, I don't think Europeans would particularly care about those problems in Russia. It only really became problematic when the order of the continent was threatened, and even then it took some serious arm-twisting to get certain members of NATO and the EU to commit to measures to do something.
This is how science works. Our understanding of a medication's efficacy evolves over time.
These reports only make sense to me if I take a "substitution model" in mind. My idea being that it is not likely that alcohol itself is healthy, but there are some pretty good feedback loops that prevent people from drinking too much alcohol that don't really exist for many of the replacement drinks.

As such, many people that drink "moderately" also drink less of all things. Often times, their "one drink with dinner" is all they drink, period. Contrasted to the bottomless soda drinks that are also on offer.

Granted, I'm still not clear I have internalized my few trips to other countries. I had assumed people would drink more water. I was, evidently, very wrong. It is still puzzling to me how little water I was able to get on the regular when out.
Tyvm for the serious comment, i_am_proteus! :-) The algorithms book By Steve S. (The Algorithm Design Manual)?

I've read that one, not an expert by any means, and I've got a 'decent' handle on data structues, but what about the software engineering basics one needs like OOP vs. Functional, SOLID, interfaces, class invariants, class design, etc.? Should I just pick up any CS 101 textbook? Or any good MIT open courseware classes that cover this type of stuff (preferably with video lectures... intro to algorithms is _amazing_ they have Eric's classes uploaded to YouTube, but finding good resources to level-up as a SWE has proved somewhat challenging)

^ serious comment as well... I find myself "swimming" when I hear certain terms used in the field and I am trying to catch up a bit (esp. as an SRE with self-taught SRE skills that is supposed to know this stuff)
Do the post-hoc rationalizations matter? Kamala wasn’t elected in a primary and so the perception by many is that she was an illegitimate candidate. That perception translates directly to votes, the justifications for Kamala being the candidate do not.
They didn't though?

> first designed specifically for inference. For more than a decade, TPUs have powered Google’s most demanding AI training and serving workloads...

What do they think serving is? I think this marketing copy was written by someone with no idea what they are talking about, and not reviewed by anyone who did.

Also funny enough it kinda looks like they've scrubbed all their references to v4i, where the i stands for inference. https://gwern.net/doc/ai/scaling/hardware/2021-jouppi.pdf
That's not it at all. I'm sure there's lots of sycophants out there, but a lot of people just don't find "he's stupid and it's random" a satisfying explanation for his actions, even if they disagree with them.
And this stuff is why I love either super creative science fiction or travelogues (and the formers are hard to find).

You can try to imagine a brand new world or simply try to re-live our real and past world. To me that is even more amazing, as it often can be the door to understanding some things of today's cultures and/or discover lost little worlds.

Currently I'm going through this book of a guy who cycled across Central Asia and in Japan. The guy is sometimes quite direct in his writing (unlike other writers) but it's so interesting to experience the world of just 100-200 years ago through the lens of one living there. I truly recommend it.
Amazing! Thx for the recoo, arwhatever :-)
You can do real work for a few hundred dollars which is hardly the exclusive domain of "whales"?

The programmer who writes code to run on these likely costs at least 15x this amount an hour.
But in the meantime, the state has $40b of wealth under its control to invest.

And while the $100B winner may have had some insight that contributed to the $100B, there also had to be a $100B winner in an economy structured the way ours is. Consequently, we don't really know whether there's a reason to prefer their investment choices over the ones the state will make.

It currently remains unclear, for example, whether what Musk or Bezos have done with their vast wealth thus far will, in the medium or long term turn out to be a net benefit to society (it certainly has not been so in the short tem).

The belief in the business genius really is overblown. Yes, some folks are better at it than others, but when we run the economy like a casino, there will always be big winners no matter what personal qualities the players bring to the game.
I’m not expecting anything like evaporating, only that things like their share price and compensation are more like a tech company than a taxi company but they don’t have a strong moat. There’s interest around things like self-driving taxis, but they don’t own the technology so it won’t open up extra margins.
The oxymoronic style of marketing bullshit: unlimited with restrictions, free but only if you pay, lifetime membership for three years, etc.
Given my exposure I've loaded up with long puts right after this news.

Puts are a necessary hedge now for your 401ks or stock grants.

Don't be discouraged that it is in Ruby as the concepts are completely general. Great watch even though I never coded a line of Ruby.
> There are a large number of fundamental impedance mismatches between relational data and object based data

My experience tells me that the largest among these impedance mismatches is the inability for OOP languages to express circular dependencies without resorting to messy hackarounds. Developers often fail to realize how far they are into the dragon's den until they need to start serializing their object graphs.

I think expecting the government to figure out your meaning off life is putting a bit of to much responsibility there.

There's actually a really good argument in favour of that -- and in favour of paying income tax not as a direct tax (withheld from wages) but with a delay.

It makes the taxes visible and painful and they will therefore (potentially) not rise as fast or as much.
I buy that it is able to produce a large volume of code, sure

Sometimes it might even be functioning code. Infinite monkeys with infinite typewriters eventually produce something right?
That might be true, I wouldn't know -- but I do know a lot of EU countries have visas for skills shortages and software is listed among those skills. I assumed that meant there's an opportunity to expand and expedite access if the need was more imminent.
==1. People will stop working if they don't need to and won't need to in future. This is obvious to anyone who has met people.==

You are arguing against a proposal nobody is making. In this study, €1,200/month isn't really enough that people wouldn't need to work. The average wage in Germany was €4,479/month in 2023.
But genuine question : Is it necessary and for what goal ?
This isn't true and has been tried in the Nordic countries.

This is an outstanding article on the subject:

> Any project trying to use deterministic symbolic logic to represent the world fundamentally misunderstands cognition.

The counterposition to this is no more convincing: cognition is fuzzy, but it's not really clear at all that it's probabilistic: I don't look at a stump and ascertain its chairness with a confidence of 85%, for example. The actual meta-cognition of "can I sit on this thing" is more like "it looks sittable, and I can try to sit on it, but if it feels unstable then I shouldn't sit on it." In other words, a defeasible inference.

(There's an entire branch of symbolic logic that models fuzziness without probability: non-monotonic logic[1]. I don't think these get us to AGI either.)

I don't doubt that a lot of it is a fad.

But I think we are in the early stages and we really do not know what is going to work or not. People are hyping their own stuff to get funding or customers.

I am taking things slow. Trying out stuff like PydanticAI and simple mcp stuff.
If everyone who stayed home had voted for the same third party, it would have won. That's unlikely.

It's also unlikely that it would have been split between only two additional parties. In my state we had 5 parties on the ballot. Colorado (to pick one at random) had 12.

If there was any real movement to get non-voters to vote for a third party, there would likely be even more of them. As it is, each of those parties took a fair bit of effort to get on the ballot, knowing that at best they would "send a message".

If the message is "we don't like you", then the message has been received, for many years. But the reply is "OK, go get people to agree on somebody else", and that's the sticking point.
Let me give you a simpler, Occam's-razorish explanation: People who voted for Trump aren't stupid, or naive, or anything. They simply were unable or unwilling to accept the world changing around them regarding race, sexuality, welfare, climate, economy, foreign and domestic policies. They elected someone who told them "we'll go back to the old times one way or another, consequences be damned".

This is exactly what they voted for, what they were hoping for. They knew leopards would've eaten the face of a few of them, but it was somewhat expected, a calculated risk. There's a few casualties even when you win the war.

They saw something they could cling to, to avoid changes for the remaining of their lives, even if this meant destroying their country, the rest of the world or the future for the matter. And they replied with "Yes, we're fine with that".

Both you and OP are not looking at this from the right angle. The goal here is to decouple US from China. In the meantime, tariffs are raised on every country to gauge which side they are on. Once US knows who the allies are, they will negotiate to have those allies put up massive tariffs on China as well to prevent transshipping.

US wants nothing to do with China. As the biggest consumer economy in the world, the have that right.

And China has shown that agreement with them has no value. Remember that China promised trump in term 1 to massively import US goods and reduce fentanyl, in part to slow trumps tariff down. They did neither of those things. Trump hasn’t forgotten that.
Would have made a similar comment if I hadn't found yours.
Google starts to inspire the same bloaty feeling as MS. I feel sad
> If I get UBI but feel lost, how do I find a sense of belonging? How do I find meaning in my life?

That's rather a separate problem. The point of UBI is to make individuals and families more economically resilient. This should have a lot of beneficial spillover effects, but it's not a cure-all for every ill.
This is a ~400 word blog about tetris, not a research paper about curing cancer. Maybe some slack can be afforded?
also dietary needs and preferences. it's way do complicated. it adds a burden not only to the administration but also to those who sell the goods and services received.

another problem is that if i earn extra money i can't combine it with the basic income to eg afford a better apartment. everyone would be stuck with the apartment given.

you end up with people who spend it irresponsibly and then need help to survive. So you end up with UBI in addition to all the existing social safety nets.

i don't believe that. if you spend your income irresponsibly you are out of luck. change your habits. wait until the next payment and do better. if you can't do that then a social worker will help you.
I don't understand why you're downvoted. I grew up in a country that did exactly this, until collapsed. Strong social nets, free housing, free medicine for all, free education, no unemployment, sounds like heaven, right?

The only problem is that every person is a government-owned livestock unit. Their thoughts, knowledge, career paths, kids, even their private life, everything is controlled by government, that also obligates you to watch after your neighbours and co-workers. You can't even leave the country without government permission. You can expelled if you don't like the government though. You can't work where you want after getting your degree, government will send you where they think they need you to be. School is never ending propaganda. We literally had "political information" every Monday, since grade 1. Also, since grade 1 you're in one of the tiers of the only allowed political party of the country. There's tier for grade 1 to 3, then for 4 to 8, then from 8 to 10. Every 18yo is drafted for 2 years for armed forces (3 for navy). I can go on and on.

I remember it too well and would never trade messy and chaotic capitalist society to that labour camp with "free" rations.

It's frightening that so many people in 1st world want to live in a cage with 3-times-a-day meal.
Ah you mean like implementing UDP and supporting complex lag masking netcode before we have to?
