I don't really care, as I didn't from the beginning because I've found popular, organized sports unsatisfactory. And Tour de France mostly unimpressive at the times, considering I had a much more heavy bike, and no car with a spare standing by in case of flat tires or other mishaps. I also did most of this in normal traffic, needing to stop at traffic lights, crossings, whatever. And watching out for all the broken glass, all the times.

From https://osm.org/go/0GIDMKQGO--?m= to

https://osm.org/go/0GC~DS4_r?m= in 25 to 30 minutes, depending on weather, traffic, whatever.

Maybe gulping down a can of coke, orange juice, isotonic sports drink, in no more than five minutes. Going back, usually 1 to 2 minutes slower, because of wind coming from the south, which is funneled there from within the Rhine valley out into the open "Kölner Bucht"(Bay of Cologne?).

Did this at least a few dozen times in this times.

Going from https://osm.org/go/0GJGHYJiY?m= to

https://osm.org/go/0GC~DS4_r?m= again.

This time with a classmate on a much better bike, and member of a cycling sports club.

In nineteen minutes! Classmate almost collapsed on arrival. Though the first third to quarter of that track goes slightly downhill. Anyway, don't remember the time back, because I didn't want to give my classmate health problems, so we took it slowly.

Then, in another temporary 'home turf' for about a year, from here https://osm.org/go/0GI2sXyvp-?m= to

https://osm.org/go/0GJpBsflN?m= which is very hilly with many steep inclines, ups and downs, on all available routes.

Twentyone minutes! Up to 25 on my way back. Did this at least several dozen times in that time. "Progressive" car drivers take 25 to 30 minutes on that route. 'Normies' more like 35 to 40.

Also did countless other tours from my first OSM-link to Aachen, Koblenz, Hagen, and up into the Eifel, to the big radio-telescope in Effelsberg, then mostly downhill through curved roads back to the Rhine, and back home along it. Also tours through the https://en.wikipedia.org/wiki/Siebengebirge on the other side of the Rhine to Siegen, or just up the https://en.wikipedia.org/wiki/Drachenfels_(Siebengebirge) instead of taking the cog-wheeled train ;->

All in rather good time, maybe not for the first time, but when I knew the road(s) better, having built up a mental picture of the 'ideal line', hazards, and such.

There are literally two new dictation apps on Show HN every week: https://hn.algolia.com/?dateRange=pastWeek&page=0&prefix=fal...

This one is unique in that it supports iPhone. I haven't seen mobile support very often.

Despite all these apps, there are two things holding me back from using a dictation app on a regular basis:

- streaming transcription: see words in realtime

- multimodal input: mix voice with keyboard

So I started prototyping this type of realtime multimodal dictation UX: https://rift-transcription.vercel.app

This HN comment captures why streaming is important for transcription: https://hw.leftium.com/#/item/47149479

Same can be said of search engines, encyclopedias, or wikis compared to seeking out books, journals, and other source material. If you don't sit there for 8 hours in a library to find the same information on your own, you've missed out on the experience. It's a standard Luddite's argument. Tools of any kind that enhance efficiency have always actualized lazy outcomes. It has always been the human responsibility to, not only rely on their best effort, but to figure out what actually encompasses their best possible effort.

Linux on PS5 seems absolutely amazing.

Anybody running any AI models using the GPU of PS5 or using the ram (16GB).

PS5 is probably sold at a loss/bare minimum profit to turn profit during the gaming product itself, not the hardware as compared to the steam machine

So running Linux on PS5 is so freaking cool. Gonna have to share this article with my brother who owns one.

This reminds me of that time when US govt. bought 200 PS3 or similar and hooked them up all together to make a supercomputer because this way it costed them less than having a computer themselves and Today's ram prices being 5 times higher in such short term is yea.

PS5 hacking community feels really cool!
Show HN: Detect any object in satellite imagery using a text prompt
by eyasu6464 | 2026-03-08 13:51:36+00:00
I built a browser-based tool that uses Vision-Language Models (VLMs) to detect objects in satellite imagery via natural language prompts. Draw a polygon on the map, type what you want to find (e.g., "swimming pools," "oil tanks," "solar panels"), and the system scans tile-by-tile, projecting bounding boxes back onto the globe as GeoJSON.
The pipeline: pick zoom level + prompt → slice map into mercantile tiles → feed each tile + prompt to VLM → create bounding boxes → project to WGS84 coordinates → render on map.
No login required for the demo. Works well for distinct structures zero-shot; struggles with dense/occluded objects where narrow YOLO models still win.

Anyone providing hosted inference for 9B? I'm just trying to save the operational effort of renting a GPU since this is a business use case that doesn't have real GPUs available right now. I don't see the small ones on OpenRouter. Maybe there will be a runpod serverless or normal pod template or something.

Also does 9b or 9b 8 bit or 6bit run with very low latency on a 4090?
by vardalab | 2026-03-08 13:53:07+00:00
Q4 quants on 32G VRAM gives you 131K context for 35BA3B and 27B models who are pretty capable. On 5090 one gets 175 tg and ~7K pp with 35BA3B, 27B isaround 90 tg. So speed is awesome. Even Strix 395 gives 40 tk/s and 256K context. Pretty amazing, there is a reason people are excited about qwen 3.5
Show HN: Country Cockpit – What countries trade, in real objects
by kevinBrk | 2026-03-08 13:53:38+00:00
I built a dashboard that tries to make country-level economic data actually understandable.

Instead of "$X billion in exports," it shows Italy shipped 96M dresses, 11K yachts, and 2.1B liters of wine.

Screenshots: https://imgur.com/a/kuxWr55

Covers 37 countries across trade (UN Comtrade), government spending (OECD/COFOG), revenue, debt, strategic resource dependencies, and 24 World Bank indicators.

Stack: Next.js + React + D3.js, FastAPI + SQLite backend.

Not live yet, sharing screenshots for feedback before launch. Curious if this is useful to anyone, or if I'm building for an audience of one.

Pgvector is definitely the easiest way to get started. I did not really get the problem the article was trying to sell.

Setting up an ingestion pipeline to your existing db, vs ingesting into yet another db seems to not solve a problem I have.

If there was one thing I wish pgvector was better at, it would be to allow composite indexes (ie find vector where category). But it's a minor point.
by remembradev | 2026-03-08 13:54:27+00:00
Great work on Engram. The consolidation and contradiction detection features are smart additions - episodic to semantic is exactly how human memory works.

We've been working on a similar problem with Remembra and hit 100% on LoCoMo with a different approach: entity graphs + temporal decay. The insight was that knowing WHO you're talking about (resolving 'Mr. Kim' to 'David Kim') matters as much as what was said.

Curious about your spreading activation implementation - are you doing this at query time or pre-computing the graph connections?

by kencho | 2026-03-08 13:55:05+00:00
fair point on the framing. we do use vector search internally, so calling it "not a vector database" is a stretch. the argument i was trying to make is more narrow: most teams evaluating pinecone or qdrant don't need to operate the vector layer themselves. they need search results from an api call. whether that api uses vectors, BM25, or hamsters under the hood shouldn't matter to them. i could have been clearer about that

We're using cloth diapers for our daughter (6m). She's still exclusively breastfed so no solid poops but so far I estimate we've saved over $100/mo by this decision.

The story may change when she starts on solids but I recommend everyone to try out cloth diapers, just make sure you have a routine and system in place to make it less overwhelming (we have two diaper pails next to the changing table, one for disposable wipes and one for the diapers, every other day we wash the diapers and liners).
by remembradev | 2026-03-08 13:55:23+00:00
Interesting take on avoiding vectors. We landed somewhere in between with Remembra - hybrid search (vectors + BM25 fusion) but the real win came from entity resolution.

The insight: most 'memory failures' in coding sessions aren't retrieval failures, they're identity failures. The agent knows you mentioned 'David' and 'Mr. Kim' and 'the client' - but doesn't know they're the same person.

We added automatic entity graphs that link these references, so when you search for anything about the project, you get the full context of WHO was involved, not just what was said.

Re: append-only vs rewriting - we do both via temporal decay. Old memories naturally lose salience over time (Ebbinghaus-style) unless they keep getting referenced. Lets you avoid explicit curation without accumulating noise.

I’m 40, and I’ve spent most of my life alone. To be clear, I’m an introvert, so being by myself is something I’m quite used to. Still, I think I have some experience that might be worth sharing:

1. Find something that’s truly yours. Remote work is fine, but having a personal project you genuinely enjoy is a completely different feeling. Try to find something like that.

2. Fill your day with structure. My day starts with reading and studying languages, then I go for a walk, work, read and learn more things, and relax in the evening.

3. Walk more. This habit is hugely underrated. One or two hours of walking a day, especially in the sun, can brighten even the darkest day.

4. Exercise. Almost everyone talks about it — because it works. And it works really well. The key is consistency.

5. Travel if you can. You’ll get a lot of new impressions and meet many interesting people.

6. Don’t just play games — watch them. I’m serious. As silly as it might sound, let’s plays can genuinely help with loneliness. There’s even research suggesting that people in streams can sometimes ease loneliness better than real-life friends. If games aren’t your thing, find streams on topics you enjoy.

7. And finally: as others here have already said — try to find yourself and understand yourself. Often loneliness isn’t about the absence of people, but about not being able to accept who you are.

That does strike me as pretty early but hey, I’m sure it happened and it still happens! But I do agree with the core thesis that people seem to be waiting a very long time. How long is “too long“ is hard to determine though if you ask me. Potty training is not just about when your kid is ready, it’s also about when the parents have capacity to handle it because frankly it is an incredibly intensive, involved, messy process that usually takes several days if not weeks. It also usually has setbacks and even full resets.

One of my kids we started at 18 months and he almost got it but we started to see serious regression and had to pull back. We then tried again a few months later and he was good to go. I think it is very reasonable to have your kid potty trained by 2 for most people, but that is mostly based off my experience and that of my peers, not some sort of data driven observation or something.

Also, and this may seem obvious to folks but it’s worth mentioning, it’s of course easier to potty train your kid the older they are. So some people know that they could do it sooner but decide that it’s worth just waiting a little longer so that the process is easier. That’s valid!

I haven't been in your situation, but if my wife and I separated for whatever reason, I suspect I probably would be. I find being social and trying new things to be incredibly difficult. So it's something I've thought about. Personally I would not try to adapt to being alone, but rather I'd try to find & meet new people.

I would suggest trying to find in-person employment, whether that means changing to a job with a local office, or finding a co-working space to go in to. Then go in to the office every day. You can do less frequently than that, I guess, but it will just increase the time it takes for bonds to form. It turns out if you're a decent person to be around, it's almost impossible to not make social connections if you have lunch with the same people 5 days a week, 50 weeks a year. For both my wife and I, the vast majority of our friends are people we met at work, or through people we know at work. There are other ways to make friends, of course, but work is one of the faster & more reliable sources IME.

My other suggestion would be to get back into the dating pool when you feel more ready for it. It's an environment where everyone is expecting to meet new people and try things out and maybe things don't work and that's OK. I think dating is a lot different in your late 30s than it is in your early 20s, much more casual & experienced and hopefully less stressful. Even if it doesn't work out romantically, it's a way to get some practice meeting people and talking about yourself, and maybe make some new platonic friends and get out of the rut.

People suggest hobby groups, but I dunno, I've tried that and it never really works out for me. I'm very shy and have a hard time inserting myself into an existing group. The infrequency of meetups also means it's hard to give the time for bonds to form, especially for someone fairly aloof like myself. That said I have started going to a weekly Fighting Game tournament and that might be working out.

Just some ideas from my own ruminating on this issue. Hope you can find something that works for you.

pgvector is great if you're already on postgres and only need text search. funny enough, Neon Postgres actually featured us in a case study about this exact topic. we replaced pinecone and rds with neon under the hood:
https://neon.com/blog/vecstore-replacing-pinecone-and-rds-wi...

the gap shows up when you need image search, face search, or content moderation on top of text search. that's where a dedicated api makes more sense than rolling your own on postgres

Thank you for the kind reminder! I have removed the duplicate.

You made a great point. Since the original authors are the same, the fundamentals of the Emacs C core are indeed highly compiler-optimized. I hope I can come up with a way to fully understand and write about that history and relationship. (But to be honest, diving into that level of compiler history is a really hard topic to tackle!)

Thanks for the great inspiration and for taking the time to read!

We are doing both lol. The questions I ask and edges i get are completely different from the questions someone else may ask. And we saw our friends in college and after go into generational debt sports gambling and on prediction markets and 0DTE options plays because they thought they had an edge but didnt have the stats knowledge to know it was fake. And this good for brokerages too so we are trying to sell to them too

No, you did not understand correctly. They are not “literally giving things away for free”, they are providing a very conditional free trial, which is a business decision and not anything new. Then a commenter speculated they might extend that program because they didn’t say they won’t and I pointed out it doesn’t make sense to assume they will. No one on this immediate thread made any complaint, we’re discussing the facts of the offering.
Show HN: Moruk OS – Autonomous AI agent that runs locally on Linux
by FiratBulut | 2026-03-08 13:58:44+00:00
I built an autonomous AI operating system that runs locally on Linux.

It's not a chatbot — it decomposes complex tasks into subtasks, executes them autonomously, writes and runs code, browses the web, and learns from every interaction.

Key features:
- Multi-model support: Claude, GPT-4, Gemini, Groq, DeepSeek (any OpenAI-compatible)
- Project Manager: breaks down projects into subtasks and executes them in parallel
- Persistent memory (vector + SQLite)
- DeepThink: secondary reasoning layer that reviews critical actions before execution
- Plugin system: drop a .py file into plugins/ and it's instantly available
- Real-time Live Activity window showing every tool call as it happens

Built with Python + PyQt6. MIT license.

Looking back my wife and I have said that we could probably have done cloth diapers during the breast-feeding phase but man… Definitely not with solid foods. I don’t know how people did it. Like yes of course if we didn’t have an option we would do it, but with disposable diapers right there… There’s no way I’m ever choosing cloth diapers and solid foods lol

It is objectively bad writing:

Overuse of stylistic methods

Melodrama even when discussing the mundane

Attention grabbing tricks like binary opposites overused

Overuse of adjectives and adverbs in particularly inappropriate places.

Lack of coherence if you’re generating large bits of text

General dull tone and lack of actual content in spite of the tricks above

Your assertion at the end - sure if I didn’t know I’d think it was a particularly stupid melodramatic human who didn’t ever get to the point and avoid their writing at all costs.
Looking for ArXiv Endorser in Cs.ds"
by esuryadi | 2026-03-08 13:59:57+00:00
I'm looking for an arXiv endorser in the cs.DS (Data Structures) or cs.DB category.

I've spent the past week developing a novel hierarchical data structure called the Omni Axis Tree (OAT) — a multi-parent, multi-dimensional tree with O(1) exact retrieval via bidirectional indexing. It achieves 193× faster retrieval than DAG traversal and 64× faster than vector search at 50,000 nodes, with retrieval time staying flat as dataset size grows.

The structure has applications in AI agent memory systems, enterprise knowledge graphs, and cross-dimensional analytics.

I have a research paper ready for submission and a provisional patent filed (U.S. App. No. 63/999,482).

If you've published on arXiv in cs.DS or cs.DB and would be willing to endorse my submission, I'd be very grateful. Happy to share the paper first so you can evaluate it.

Feel free to DM me or drop a comment below.

Thank you

In my opinion if you're searching for a hobby it's best to be a bit more methodical about it. Usually the way to get into hobbies is that a friend or acquaintance pulls you into it (either by talking about the hobby energetically or directly showcasing it) and going at it from the other end isn't really easy per se in my experience.

But yeah, it's more than doable. First things first take a piece of paper (or do it digitally) and divide it into 2 halves, indoor and outdoor, then further divide those 2 halves into solo and group. At this point it doesn't make sense to take financial constraints into account, that's up to it at the end as a determining factor if you want to start a hobby from your "short list".

So after you've done the above take a week to fill the paper with stuff like "Tabletop RPGs" which goes into indoor/group, or "nature photography" which goes into outdoor/solo and I hope you get the jist. I'm sure you know where to file embroidery for example.

You can continue to add hobbies as a hobby too for a little bit, call it hobby watching and searching, it's still a pastime. Now here's another important part, you have to decide your motivation for start a hobby (not a specific hobby but a new hobby). Some people try and do hobbies because they feel they're forced to if they want to appear interesting to their peers, sometimes you just want to fill a hole or fill time so you can't stop and think about that hole. In emotionally adjusted individuals supposedly you can pick a hobby for the fun of it and that's enough. Basically do a bit of soul searching so that you can decide if you gravitate towards a outdoor hobby with a group of people (because the hobby itself doesn't matter that much but you crave connection which is completely fine and that's why some old people go to church).

I could go on but thanks for reading my TED talk and I really hope you find what you are looking for, either a hobby or something else.

Vagrant was a layer over virtualization, with hypervisors like virtualbox, kvm or vmware. The article mention virtualization and virtual machines several times, e.g. "unlike the virtual machine experience (which involved installing an entire operating system)".

For instance, deploying a complex Python application was hell, for lack of proper packaging. Using Vagrant was easy, but the image was huge (full system) and the software slow (full virtualization), among other problems. Containers like LXC and Docker were a bit easier to setup, much smaller, almost as performant as native packaging, and with a larger spectrum of features for sharing things with the host (e.g. overlay mounts).

No it isn't. IT IS A WAY OUT.

The west only accepts Iranian women with degrees (or any other place for that matter, if they accept anyone at all).

In other words, yes, the islamic revolution is making women smarter. Men too, but not to the same degree. But in the worst way possible. By putting a gun to their head and torturing them non-stop, then effectively letting the smartest 5% out.

Yes regime apologists want to call that "making women smarter" because "torturing women", what islam actually does, sounds ... unlikely to gather support for stopping the war and it's not like they care about them.
Show HN: Krust – fast, open-source Kubernetes TUI in Rust (k9s-style UX)
by erfany | 2026-03-08 14:02:01+00:00
Hi HN,

I built krust because I kept hitting the same pain: Kubernetes terminal tools that felt slow on large clusters, or useful features gated behind paid tiers. I love k9s, but for my clusters, it is not as fast as I like it to be.

This is my attempt at an alternative:

- Rust-native TUI focused on low latency

- k9s-compatible navigation and commands (no plugin system though)

- multi-context + large-cluster oriented

- logs/streaming, describe/edit/apply, secret decode, readonly/guarded mutation flows

Repo: https://github.com/ErfanY/krust

It’s still early, and I’m sure there are rough edges. I’d really value community feedback, especially from people running many clusters/resources.

If this helps you, great. If it doesn’t yet, I’d appreciate blunt feedback on what to fix next.

I personally have used Qwen2.5-coder:14B for "live, talking rubber duck" sorts of things.

"I am learning Elixir, can you explain this code to me?" (And then I can also ask follow-up questions.)

"Here is a bunch of logs. Given that the symptom is that the system fails to process a message, what log messages jump out as suspicious for dropping a message?"

"Here is the code I want to test. <code> Here are the existing tests. <test code> What is one additional test you would add?"

"I am learning Elixir. Here is some code that fails to compile, here is the error message, can you walk me through what I did wrong?"

I haven't gotten much value out of "review this code", but maybe I'll have to try prompting for "persona: brief rude senior" as mentioned elsewhere.
