I know what you&#x27;re thinking... and I still can&#x27;t believe it, but...This morning, our database flagged a duplicate UUID (v4). I checked, thinking it may have been a double-insert bug or something, but no.The original UUID was from a record added in 2025 (about a year ago), and today the system inserted a new document with a fresh UUIDv4 and it came up with the exact same one:b6133fd6-70fe-4fe3-bed6-8ca8fc9386cdWe&#x27;re using this:
https:&#x2F;&#x2F;www.npmjs.com&#x2F;package&#x2F;uuidI thought this is technically impossible, and it will never happen, and since we&#x27;re not modifying the UUIDs in any way, I really wonder how that.... is possible!? We&#x27;re literally only calling:import { v4 as uuidv4 } from &quot;uuid&quot;;const document_id = uuidv4();... and then insert into the database, that&#x27;s it.Additionally, the database only has about 15.000 records, and now one collision. Statistically... impossible.Has that ever happened to anyone?! What in the...

Ask HN: We just had an actual UUID v4 collision...

AI hallucinations are getting ambitious.A couple people recently emailed, asking whether the Klein bottle business was still operating after my death.“Huh?” I thought. “I ain’t dead yet.”After some digging, I discovered the source: an AI-generated review of The Cuckoo’s Egg circulating on Facebook. Alongside the usual synthetic praise and fabricated details, it confidently announced that I had died in May 2024.Apparently AI has now advanced to the point where it can kill people off before they notice.Mark Twain once wrote, “Reports of my death are greatly exaggerated.” I never expected to field-test the quote personally.source: https:&#x2F;&#x2F;www.facebook.com&#x2F;story.php?story_fbid=989939243570691&amp;id=100076638743004Cheers, -Cliff

Rumors of my death are slightly exaggerated

Not exactly technical, but HN feels like the correct crowd to ask because asking anywhere else I would be considered mentally ill.I have a tinnitus that seems to stay 99,9% of the day, it’s away for some minutes sometimes and it’s very high frequency. Imagine a power supply coil whine.Now the mentally ill part: the tinnitus can change position (left&#x2F;right ear) and change volume. I didn’t hear the tinnitus on the right ear for some days, now it’s back on it (and still audible on the left ear) after sitting on the couch again.The couch, you ask? Two weeks ago, when the tinnitus started, we changed the layout of our living room. The couch was now located next to our WiFi router. The tinnitus started shortly after that. I never had tinnitus before. Guess what, the router makes the same noise (even my partner can hear it). After some days of realizing it might be from the router, I changed the position of it to the other side of the room, but now somehow I can still hear the high frequency from the router from 3 meters apart. And as soon as I start sitting on the couch, the tinnitus gets much worse. Even disabling electricity in the full house I still hear that WiFi router noise in my ear.Am I insane? Is this a thing? Can some frequency cause a tinnitus which can be re-triggered by the same frequency? Can it have a memory effect? Could it be it doesn’t go away even if I don’t sit on the couch for days because all these power supplies have high frequency coil whine in each and every facility these days, which trigger it again?I feel like Neo from The Matrix who got enlightened and now can hear electricity, but without the rest of the super powers :(PS: I visited a doctor and am doing the usual medical procedures to deal with tinnitus (Prednisolone 60mg&#x2F;day), but it doesn’t help in any way.

Ask HN: Can a tinnitus be triggered by high frequency noises?

So to keep a very long story short, I was 28, was exactly a year ago from april i was awarded top 2000 technicaians in the Nation from Stellantis of North America. I was(and still am) dealing with life long knee pain and hip pain from just wear and tear of automotive repair. Due to this i knew automotive was over for me. Then I discovered claude.ai and one question led to another text thing you kmow im building a dual rtx msi b550 tomohawk max wifi 64gb ram, amd am4 5900xt cpu. 3tb ssd nvme ssd. Within 2 months of discovering the potential of CS. That said. I ended up creatinf a ton of projects to teach myself. Mind you im doing all this while the world around me is crashing and burning. I built printmakerai.com. I know ai is amazing at coding, and is very useful, but im the kind of guy who firmly believes &quot;if you want it done right you must do it yourself.&quot; The reason im posting this is im seeking advice on what I should do. I cant land a career in cs without a formal degree. Im coming from one of the most technically advanced trades there are. We aren&#x27;t &quot;mechanics&quot; anymore were technicians and for good reason. I can directly translate canbus, sensor fusion,.redundant systems, trace wiring diagrams,Seperate circuits and modules and accurately Diagnose a module, circuit or more. Heck I was able to translate oil wicking to solder wicking. Like how 2018+ wranglers throw excessive dash lights and can stall? Everyone assumes abs module because the abs is throwing the dtc and there was a year plagued with bad abs modules. But its really a starconnector behind the glove box that has solder wicking down the pcb. And even being this smart is clearly not enough to land me a job in any real cs world. Thanks to claude.ai I found what makes brain light up like a Christmas tree but genuinely need help navigating this confusing field. That said ill be treaching myzelf python today because we&#x27;ll I cant code myself lmao. And I know thats blocker number 1.

Ask HN: Former master-tech building AI systems – how to break into software?

My understanding of the early Internet is that there was fierce competition among commercial, closed-source server and database software, and that the dominance of Linux, Apache, MySQL (and now PostgreSQL) etc were far from obvious or guaranteed. I think we’re in a similar moment with LLMs, and I’d love to read some stories, or see some examples of discourse on mailing lists, forums, or whatever on this subject from that earlier period. I think it would be helpful for grounding present-day discussions. What can you share from this era?

Ask HN: Before Open Source took over the server, what was the discourse like?

With the lowering usage limit in Claude, I am thinking of jumping ship to Chinese AI, since the benchmark is already very near compared to Sonnet or Haiku 4.5 , but for a fraction of the price. I am not worried about where is my data ending up through, I am focused on performance and usage limit. I mostly use it for coding and research.However, I am currently deciding on which to use, and would love any recommendations from anyone that are using any or many of these AI,- GLM Coding Plan (Z AI): $18&#x2F;month Lite Plan
- BytePlus: $10 ModelArk Coding Plan
- Kimi AI: $19&#x2F;month Moderato Coding Plan
- MiniMax: $20 Plus Standard PlanI would like to ask, is the performance good? Is it worth the value? And how is the usage limit? Also, if anyone have any good recommendation on AI plan that is only in Chinese language, I don’t mind too, as I can understand Chinese.

I am an engineer at a small organisation - there is no question of budget being available to buy us accounts with any of the major model providers. How are other folks in my position managing to keep their AI integration skills up to speed? Most free or low-budget courses I see online - e.g. at DeepLearning - seem to assume a paid account. At the moment i cannot justify that outlay.

How are folks affordably self-training in AI?

HiI believe LLM are really cool in generating DSL code. If one provides well structured and clear prompt.I am the author of Sparrow ( https:&#x2F;&#x2F;github.com&#x2F;melezhik&#x2F;Sparrow6&#x2F;blob&#x2F;master&#x2F;documentation&#x2F;taskchecks.md ) DSL for text parsing and automation with SDK for many programming languages , and I am really impressed how well deep seek generates parsers and compliance checkers for different configuration files - sudoers, sshd, redis, forgejo to name a few. Here are just some examples:- forgejo - https:&#x2F;&#x2F;chat.deepseek.com&#x2F;share&#x2F;y3f2om2b6hvzcm752h- redis - https:&#x2F;&#x2F;chat.deepseek.com&#x2F;share&#x2F;9eakpdlaa6b88e38u3- sshd - https:&#x2F;&#x2F;chat.deepseek.com&#x2F;share&#x2F;1roo31ihmuz10xjxem- sudoers - https:&#x2F;&#x2F;chat.deepseek.com&#x2F;share&#x2F;is2ey6vgbhvdbyqtoaHere are two prompts I use :- With Python SDK - https:&#x2F;&#x2F;gist.github.com&#x2F;melezhik&#x2F;d57132c9d3ba0ae9cee30a7c04c98399
- With Raku SDK - https:&#x2F;&#x2F;gist.github.com&#x2F;melezhik&#x2F;6f25775aab9f5ec2e22f1193e7ca824bYou may choose any of them replace words sshd&#x2F;forgejo by any word of your interest and try it out with free deep seek chat bot, expert level with browser, have funPS you’d better try Raku SDK prompt as it handles configuration files with logical groups ( ini style ) as well , but you can easily modify the Python one by stealing the phrasing from Raku prompt

Recently, I am seeing lots of startups with multi-agent platform, where you can create your own agent template, attach tools and run it reliably.Which frameworks, platforms are you using for these kind of multi-agentic platforms?

Ask HN: What is the underlying stack behind multi-agent platforms?

I have been a user of openbsd for years. recently due to hardware failure and poor support of my replacement hardware on openbsd i decided to give NetBSD a try. What a mistake. Nothing just works.Commands fail or hang with no visible error.SSH does not pass the local terminal to remote (never had experienced terminal degradation just from ssh before)Normal keys like backspace and arrow do not work by default.Select to copy from xterm to ssh xterm is broken.Launching certain shell commands having to do with set in xterm brings down the whole xserver.firefox brings down the whole xserver inexplicablyno installurl default to add packages from.su keeps the user&#x27;s environment.just an all around pile of garbage if you are looking for something you can set up and work with without hours of tinkering.in contrast if you set up openbsd it WORKS out of the box and what needs to be configured is logical and documented.I can see no benefit in an OS that is unusable for productive work by default.looking for specific help with a normal terminalssh to remote without buggering the terminalselect to paste between xterm windowsnormal keyboard operationsfirefox not locking or crashing x. this is another thing: firefox on openbsd does not lock x. on my netbsd system while firefox is launching all other windows in x are frozen.

I&#x27;ve used Notion for a long time but I&#x27;m interested to hear what other alternatives exist in 2026?For me the main requirements are:* Backed up to cloud* Has a mobile app that is easy to make small changes (for example if I&#x27;m doing an oil change on my car I need to be able to pull out my phone and log it in the wiki easily)* Simple file format like markdown so that you&#x27;re not locked into something proprietary (no need for crazy formatting options like MSWord)* Option to export data out as a backup* Allow uploading arbitrary files like PDFs, images, receipts etc...* Nice to have: support for inline tables of data with simple calculations&#x2F;sorting

I&#x27;m researching pain points around manual workflows that haven&#x27;t been automated yet.Specifically looking for tasks where:
- You do the same thing 5+ times a week
- You&#x27;ve looked for a tool but nothing good exists
- You&#x27;d pay $10-20&#x2F;month if something just workedWhat&#x27;s yours? Curious to hear both technical and non-technical answers.

Every post that reaches the top of HN will have at least a few comments saying &quot;This is LLM!&quot;It has become a proxy for &quot;I don&#x27;t like this article, so it must be a LLM&quot;To me, it feels like lazy karma farming, as these comments often do get a few upvotes.And of course, accuse a 100 posts if being LLM, you are guaranteed to be right at least once, then like astrologers you can claim success.Is there anything we can do to discourage this type of lazy and low effort posting?

I’m not trying to brag, I am just genuinely confused. I got laid off recently and I had a new job within a week because I constantly get contacted by recruiters both through LinkedIn and directly by email. I’ve never sent an application to anyone and I’ve had dozens of interviews in the past year while I was looking for a new job before getting laid off.I would have had a new one earlier except I was aiming for fully remote and a big raise, and I failed their correspondingly difficult evaluations. Never got ghosted, never had to deal with AI, never had to fill out an application. I took a local, in office offer that I would have ignored if I were still employed.Currently I’m waiting for a final decision from another fully remote company and I’m in midstage with 2 more.I’m not a super genius engineer, and I don’t have any fancy companies on my resume. How unusual is this experience?

Ask HN: Is the Job Market Actually Bad?

As developers, We are using very powerful llms.But pricing are getting higher day by day.Many developers start to get mac mini for local llms.At the end of the day, are we gonna back to not very powerfull llms because of costs? What Do you think?

I have been trying to become an individual developer for a period, and have developed several tools or little projects (mainly open source). Some of them actually are very helpful at least to me, but unfortunately I am the only one to use them.No pull requests, no issues, even no stars except the only one from myself. I found it hard for them to be seen. I feel down because if there are no users, I can&#x27;t get any feedbacks and it&#x27;s hard for me to improve my projects. I feel trapped into a hole and can do nothing but to stay at the origin and get drowned.How can I promote my open-source projects (and maybe products in the future) ? I&#x27;ll really appreciate it if someone with related experiences can offer me some advice.

Ask HN: How to start up as an individual developer?

At my company engineers are producing a high quantity of PRs with the help of AI agents. QA was already the bottleneck since the software involves camera flows across multiple devices, now this is more so the case.
